A raising roller transmission mechanism with periodically changing transmission torque and a raising machine thereof

Abstract

The present invention discloses a raising roller transmission mechanism with periodic changes in transmission torque and a raising machine thereof. The raising roller transmission mechanism includes a driving pulley, an angle pressure pulley, a raising roller pulley, and a transmission belt. A plurality of idle pulleys are provided around the outer periphery of the raising roller pulley. The transmission belt includes a transmission belt I and a transmission belt II. The transmission belt I is wound around the driving pulley, the angle pressure pulley, the raising roller pulley, and an odd number of idle pulleys. The transmission belt II is wound around the driving pulley, the angle pressure pulley, the raising roller pulley, and an even number of idle pulleys. The raising torque is generated by the transmission belts I and II. The present invention sets the belt transmission as an intermittent transmission, so that the belt transmission generates a periodic change in the raising torque, reduces the belt transmission torque, and allows the needle cloth to hold the cloth for a long time during raising, resulting in a long hair feeling and a gentle raising force. This improves the raising tension, helps reduce the curling of elastic fabrics during raising, and reduces the edge center difference of low-weight loop pile fabrics.

Description

Technical Field

[0001] The invention relates to the field of textile finishing equipment, and in particular to a raising roller transmission mechanism with periodically changing transmission torque and a raising machine thereof. Background Art

[0002] At present, when the raising rollers (evenly distributed on the cylinder) of the raising machine work normally, they need sufficient raising torque. This torque is transmitted by the driving wheel located on the lower side of the cylinder through the raising roller transmission belt. The raising roller transmission belt needs a certain tension to ensure the transmission of torque. The torque that can be raised by the belt-type raising machine is generated by the transmission of the raising roller belt; the belt transmission form of the raising rollers of the belt-type raising machines on the market is all full-belt type (such as Figure 8 As shown); Figure 9 and Figure 10 As shown, the raised fabric is in the raising process in section AB, and the raising roller drive belt drives the raising roller pulley in section CD to provide raising torque for the raising roller. The characteristic of this type of belt drive is constant transmission torque, which is more suitable for fabrics that require a larger raising torque. However, when processing elastic fabrics with large tension, the curling edge is also larger, and the raising torque of low-weight fabrics is too large, resulting in edge-center difference (the raising quality in the middle is inconsistent with that on both sides). Summary of the Invention

[0003] The technical problem to be solved by this invention is to provide a raising roller transmission mechanism and raising machine with a periodically varying transmission torque, thereby resolving the problems of curling on elastic fabrics and edge-to-center deviation on low-weight fabrics. The transmission belt utilizes a partially suspended transmission method, suitable for raising low-weight loop pile fabrics. The periodic variation in transmission torque ensures a longer grip on the needle during raising, resulting in a longer-lasting pile feel. Furthermore, the suspended transmission method reduces slippage, resulting in a gentle raising force, low tension, and minimal edge-to-center deviation.

[0004] The technical solution adopted by the present invention to solve the problem is: a raising roller transmission mechanism with periodic changes in transmission torque, including a driving pulley, an angle pressure pulley, a raising roller pulley and a transmission belt, the driving pulley is installed on the lower side of the raising roller; the angle pressure pulley and the pulley are installed on the frame, and a number of lifting pulleys are arranged around the outer periphery of the raising roller pulley, the transmission belt includes two groups, namely transmission belt I and transmission belt II, the transmission belt I is wound around the driving pulley, the angle pressure pulley, the raising roller pulley and the odd-numbered lifting pulleys, the transmission belt II is wound around the driving pulley, the angle pressure pulley, the raising roller pulley and the even-numbered lifting pulleys, the raising torque is generated by the transmission belt I and the transmission belt II; the sum of the number of belts of the transmission belt I and the transmission belt II does not exceed the number of pulley grooves of the driving pulley.

[0005] As a preference, the number of the pick-up pulleys is 6 to 10.

[0006] As a further improvement, a pressure wheel is provided on the side of the hollow pulley.

[0007] As a preference, when the number of pulley grooves of the driving pulley is 6, the number of transmission belts I and II is 1 and 5 or 2 and 4 or 3 and 3 or 1 and 4 or 1 and 3 or 1 and 2 or 2 and 3 or 2 and 2.

[0008] As a preferred embodiment, the number of raising rollers matched with the transmission mechanism is an even number, which is 18-60.

[0009] A raising machine is provided with a raising roller transmission mechanism with a periodic change in transmission torque, comprising a frame, a raising cylinder, a cylinder roller, a raising roller, a cloth inlet traction device, a cloth outlet traction device and a cloth outlet and cloth dropping device arranged above the frame, wherein the raising roller transmission mechanism with a periodic change in transmission torque is fixed on the frame.

[0010] As a further improvement, the mounting locations of the lifting pulley and the pressure wheel of the raising roller transmission mechanism are provided with adjusting long holes for adjusting the tightness of the compression transmission belt, and for adjusting the entry and exit points of the belt and the pulley.

[0011] As a further improvement, the cloth inlet traction device includes a cloth inlet roller, a cloth tightening component, a brake roller, a cloth inlet guide roller and an expanding roller; the cloth outlet traction device includes a cloth outlet roller and a cloth outlet guide roller.

[0012] As a further improvement, the front and rear guide roller system includes a front guide roller and two rear guide rollers.

[0013] As a further improvement, it also includes a needle roller cleaning device and a dust suction device.

[0014] The mounting locations of the lifting pulley and the pressure wheel of the present invention are respectively provided with adjustment long holes for adjusting the tightness of the compression transmission belt. Both can be adjusted individually, or a group of overall adjustments can be adopted, that is, a connecting rod is set to connect the lifting pulley and the pressure wheels on both sides as a whole, and an adjustment bolt device is set.

[0015] The drive belt for the nap rollers of the present invention features multiple sections with hollow sections, and the transmission torque varies periodically. The number of drive belts in the two sets of nap rollers can be freely adjusted. Assuming the number of nap roller pulley grooves N, the number of drive belts in the two sets of nap rollers is N1 and N2, respectively, satisfying N1 + N2 ≤ N.

[0016] The present invention has the following beneficial effects: The intermittent transmission of the belt drive produces periodic variations in the raising torque, reducing the belt transmission torque, softening the raising force, and improving the raising tension, which helps reduce the curling of elastic fabrics during raising and helps reduce the edge center difference of low-weight loop pile fabrics. Pressure rollers are provided on both sides of the overhead pulley to ensure that the drive belt maintains a certain wrap angle on the raising roller pulley, thereby increasing the coverage of the cylinder surface.
