Brush tufting machine
Tufting is a type of textile manufacturing in which a thread is inserted on a primary base. It is an ancient technique for making warm garments, especially mittens. After the knitting is done, short U-shaped loops of extra yarn are introduced through the fabric from the outside so that their ends point inwards (e.g., towards the hand inside the mitten). Usually, the tuft yarns form a regular array of "dots" on the outside, sometimes in a contrasting color (e.g., white on red). On the inside, the tuft yarns may be tied for security, although they need not be. The ends of the tuft yarns are then frayed, so that they will subsequently felt, creating a dense, insulating layer within the knitted garment. Tufting was first developed by carpet manufacturers in Dalton, Georgia. A tufted piece is completed in three steps: tufting, gluing, then backing and finishing. When tufting, the work is completed from the backside of the finished piece. A loop-pile machine sends yarn through the primary backing and leaves the loops uncut. A cut-pile machine produces plush or shaggy carpet by cutting the yarn as it comes through to the front of the piece. Tufted rugs can be made with coloured yarn to create a design, or plain yarn can be tufted and then dyed in a separate process.
Brush tufting machine can make a lot of tufted things like toothbrushes, cleaning brushes, etc. A toothbrush is an oral hygiene tool used to clean the teeth, gums, and tongue. It consists of a head of tightly clustered bristles, atop of which toothpaste can be applied, mounted on a handle which facilitates the cleaning of hard-to-reach areas of the mouth. They should be used in conjunction with something to clean between the teeth where the bristles of the toothbrush cannot reach - for example floss, tape or interdental brushes. They are available with different bristle textures, sizes, and forms. Most dentists recommend using a soft toothbrush since hard-bristled toothbrushes can damage tooth enamel and irritate the gums. Because many common and effective ingredients in toothpaste are harmful if swallowed in large doses and instead should be spat out, the act of brushing teeth is most often done at a sink within the kitchen or bathroom, where the brush may be rinsed off afterwards to remove any debris remaining and then dried to reduce conditions ideal for germ growth (and, if it is a wooden toothbrush, mold as well). Some toothbrushes have plant based handles, often bamboo. However, numerous others are made of cheap plastic; such brushes constitute a significant source of pollution. Over 1 billion toothbrushes are disposed of into landfills annually in the United States alone. Bristles are commonly made of nylon (which, while not biodegradable, as plastic is, may still be recycled) or bamboo viscose.

Cleaning brush is a tool for cleaning a toilet bowl, which belongs to a kind of household brush tufting machine. Generally the toilet brush is used with toilet cleaner or bleach. The cleaning brush can be used to clean the upper area of the toilet, around the bowl. However, it cannot be used to clean very far into the toilet's U-bend and should not be used to clean the toilet seat. In many cultures it is considered impolite to clean away biological debris without the use of chemical toilet cleaning products, as this can leave residue on the bristles. By contrast, others consider it impolite not to clean away biological debris immediately using the toilet brush. A typical cleaning brush consists of a hard bristled end, usually with a rounded shape and a long handle. Today cleaning brushes are commonly made of plastic, but were originally made of wood with pig bristles or from the hair of horses, oxen, squirrels and badgers. The brush is typically stored in a holder, but in some cases completely hidden in a tube. An electric toilet brush is a little different from a normal toilet brush. The bristles are fastened on the rotor of a motor which works similar to an electric tooth brush. The power supply is attached without any metal contact via electromagnetic induction. In recent years, there has been a general shift in design with a new emphasis on ergonomically designed brushes. Further design enhancements have included innovative holders that snap shut around the bristled end, thereby preventing the release of smells, germs and other unpleasantries. Further development of the traditional toilet brush focus on the risk of germ incubation within the brush holder. A cleaning brush has been patented which introduces a reservoir of anti-bacterial fluid, allowing the brush to be dipped and sanitized after each use.

Sanitation brushes belong to the manufacturing range of industrial brush tufting machines. They are disc brushes or wire disc brushes installed in municipal sanitation vehicles for street cleaning, and are the most representative type of sanitation brushes. The products include sweeper roller brush, sheet-type roller combination sweeper brush, roller sweeper brush, sweeper brush, square sweeper brush, round branch sweeper brush, sewage treatment brush, scrubber brush, computer car washing machine brushes, etc. The sanitation truck disc sweeping brush is made of high-strength plastic brush wire, which is used to clean the dirt on the ground; the roller brush is used for the washing machine. Materials available are PP brush wire, PA wire or steel wire.

Welded steel pipe, also known as welded pipe, is a steel pipe made of steel plate or strip steel after crimping and welding, and the length is generally 6 meters. Welded steel pipes have simple production process, high production efficiency, many varieties and specifications, and less equipment investment, but the general strength is lower than that of seamless steel pipes. Since the 1930s, with the rapid development of continuous rolling production of high-quality strip steel and the advancement of welding and inspection technology, the quality of welds has been continuously improved, the varieties and specifications of welded steel pipes have been increasing, and more and more fields have replaced non-ferrous steel. Seam steel pipe. Welded steel pipes are divided into straight seam welded pipes and spiral welded pipes according to the form of the weld. It is classified by production method: process classification - arc welded pipe, electric resistance welded pipe, (high frequency, low frequency) gas welded pipe, furnace welded pipe. Smaller diameter welded pipes use straight seam welding, and large diameter welded pipes are mostly spiral welded; according to the shape of the end of the steel pipe, they are divided into circular welded pipes and special-shaped (square, rectangular, etc.) welded pipes; according to different materials and uses, they are divided into mining fluids Conveying welded steel pipe, galvanized welded steel pipe for low-pressure fluid transportation, electric-welded steel pipe for belt conveyor rollers, etc. According to the specification and size table in the current national standard, sort by outer diameter * wall thickness from small to large.
The lap welding machine is mainly used for the production of stainless steel decoration, products, stainless steel pipes and carbon steel pipes for household appliances and can also produce various special-shaped tubes such as elliptical tubes, semi-circular tubes and plum blossom tubes. Shearing butt welding machine is an important equipment on the welded pipe production line. It is used for shearing and butt welding of the irregular parts of the head and tail of the strip to ensure the continuous production of the welded pipe machine unit. The forming and sizing machine is the main equipment in the welded pipe production line. It can continuously roll a certain specification of long steel strip into a tube and weld it into a tube. It can produce both round tubes and special-shaped tubes. This unit adopts the principle of roll forming, and the high-frequency welded pipe can continuously produce steel pipes of a certain specification. The heating method adopts induction welding, that is, a steel strip of a certain specification is fed into the machine, and the steel strip is coiled into a tube blank through the forming roller, and then used The skin effect and proximity effect of the high-frequency current make the current highly concentrated on the welding surface of the pipe edge, so that the pipe edge is quickly heated to the welding temperature and the welding is completed under the extrusion roller, and becomes the steel pipe of the required specification after cooling, sizing and rough straightening.
