How the knitting machine adjusts the spindle belt and spindle transmission

The spindle is driven by the spindle belt. Spindles used on spinning frames have cotton webbing and rubber belts. Cotton spindle belt has large elongation, short service life and cheap price; rubber spindle belt has stable transmission, low vibration, low noise, energy saving, long service life, but the price is more expensive. In the long run, it is a development trend that rubber ingot belts replace cotton ingot belts, and it is worth promoting.
When sewing (or gluing) the spindle belt joints, installing the spindle belt reel, and adjusting the transmission parts, you should:
① The ingot belt joint should be straight, soft and reliable; the ingot belt length should be consistent. The width of the ingot belt is recommended to be 9-10mm. Tapes joints should be straight, flexible, reliable, linker length of 40mm, the linker should be directed to the same direction of the spindle rotation, twisting twisted flowers allowed, to avoid cracking and joints are not straight to reduce shock and vibration of the spindle joint. Before bonding with rubber spindles subject to a grinding length of the inclined surface (or both surfaces of the adhesive), the positioning (in the vertical rear face of the grinding overlap consistent positive fixed) on the embossing tool and the grinding surface Apply a thin layer of special adhesive, wait a while to overlap ping followed by heat caulking repair ping sides.
② Tapes of tension should be suitable for
After the same process requirements adjusted weight spindle reel spindle and the reel angle scale, suitable spindle belt tension should be about 8N, available spring scale is hooked with spindles (the middle of the two spindle) straight pulling test. Tension is too large, it will increase the bearing radial loads and increased wear on the spindle, affect the service life of the spindle; tension is too small, easy to stall, causing large differences in spindle speed, yarn uneven rate.
③ spindle to properly position with working
Whether the spindle belt is in the normal working position is important for spindle transmission. To do Tapes chassis height, front and back, left and right positioning location. The height position: reel holder spindle in vertical position, the starter plate with a top surface of the disk should be the center line of the arcuate groove of the spindle shaft on the same level. Tapes levels are too high or too low position, can cause spindle belt is not centered. Sink, lower friction bar disc spindle, spindle vibration induced shock spindle tapes, also with the lower spindle prematurely worn; floating, causing channeling spindle runout, lozenges nap edge band from being damaged, affecting both the quality of yarn breakage increases, also caused lower spindle taper some non-normal wear and tear, resulting in damage to the spindle, is lethal. Front and rear positions: with spindle chassis front touch any parts should be pushed down, and a gap of not less than 13mm, the natural swing back and forth is not tight flexible rolling, consistent swing angle, by adjusting the reel spindle carrier shaft neck the corrected angle ring. Left and right positions: The spindle belt should not rub against the spindle tray bracket or the side of the spindle tray during transmission. The surface of the spindle belt should not adhere to flying flowers or oil. In order to make the surrounding circle of the four spindles as close as possible to reduce uneven twist, the position of the spindle belt tray should be as far as possible to the left (maintain 6- -8mm clearance), the principle is not to touch the spindle belt when driving. There should be no "dead ingot belt" in the entire trolley.
In short, when adjusting the spindle belt and the spindle transmission part, we must attach great importance to it. We must be careful and careful in operating it. We must not just focus on the spindle belt driving the spindle on the spindle.

Talking about the product development of computerized flat knitting machine

Image
There are usually three ways to form knitted products: changing the fabric structure, changing the fabric density and changing the number of knitting needles. The most controllable and effective method is to change the number of knitting needles of the fabric. In this regard, the flat knitting machine is the most Flexible is also the most convenient. Especially with the development of computerized flat knitting machines, flat knitting products have developed from flat forming to three-dimensional forming, and from traditional sweaters to shoes and other decorative and industrial products.    From plane forming to three-dimensional forming The most traditional flat knitting machine forming processing method is plane forming, that is, the front piece, back piece, sleeve piece and other accessories of the clothes are knitted separately on the machine by retracting needles, and then stitched together to form the garment. Example 1: Three-dimensional fully formed garmen...

Sweater technology trends: craftsmanship and platemaking "combined into one"

Sweater technology trends: craftsmanship and platemaking "combined into one" The woolen industry is a traditional industry. In the early period of reform and opening up, the woolen industry as a labor-intensive industry solved the problem of surplus labor employment in many places, created wealth for the localities, and promoted the rapid development of the economy. Development, the impact of the international financial environment, and the increase in inflationary personal consumption, the sweater industry has gradually become burdened because it has carried too much pressure, and it is difficult to achieve the glory of the past. Known as the sunset industry. With the rapid development of domestic technology in recent years, many enterprises have introduced new computerized automatic flat knitting machines, which has solved the labor shortage problem that more and more enterprises cannot handle. The effect is obvious to all, and this sunset industry is renewed....

Factors affecting the speed of the knitting machine and points to be paid attention to during maintenance

Image
Weaving equipment has been successfully used in many places, usually used for weaving clothes, but it is worth mentioning that its long-term use will inevitably cause wear or failure, so daily major and minor repairs are done It is necessary and requires us to keep in mind some important aspects. During major repairs, all mechanical parts should be disassembled, thoroughly cleaned, worn-out parts should be repaired, and parts beyond the service life should be removed, and then be installed and adjusted in accordance with the requirements of major repairs. Major repairs are normally performed on large round machines. In about a month. At the same time, the main objectives of the key maintenance are to remove dust and flying flowers on various parts of the machine, clean the flat knitting machine parts and replace the damaged knitting needles. The large circular knitting machine mainly made of cotton yarn is in normal operation for about 6 months. We will carry out key maint...
