Device for adjusting the distance between the crushing roller and the stripping roller

Abstract

A device for adjusting the distance between a crushing roller and a cotton stripping roller, which mainly includes a cotton stripping roller, an eccentric sleeve and an upper crushing roller for transferring the cotton web on the cotton stripping roller, wherein the upper crushing roller is installed in the upper crushing roller bearing seat, the eccentric sleeve is installed in the bearing seats at both ends of the upper crushing roller, and the upper crushing roller bearing seat is installed on the frame in a swinging manner around a pin shaft, characterized in that the crushing roller bearing seat is installed on the frame in a swinging manner around a pin shaft through a pin shaft and an eccentric sleeve sleeved on the pin shaft for adjusting the distance between the upper crushing roller and the cotton stripping roller, and the eccentric sleeve forms a tight fit with the pin shaft through a nut and a locking nut. The structural feature is that the distance between the crushing roller and the cotton stripping roller can be adjusted by adjusting the eccentric sleeve, so that when the carding machine is spinning different raw materials and different raw sliver quantities, the crushing roller and the cotton stripping roller can be adjusted to a suitable distance, thereby improving the transfer rate of the crushing roller and avoiding the cotton stripping roller from returning and damaging the card clothing.

Description

Technical Field

[0001] The invention relates to the field of textile machinery, in particular to a device for adjusting the distance between a crushing roller and a cotton stripping roller in a cotton carding process or a non-woven fabric production process. Background Art

[0002] The stripping roller is the main mechanism for stripping and transferring the cotton web from the surface of the doffer wire in the cotton carding process or non-woven fabric production process. The upper crushing roller transfers the cotton web from the stripping roller and transfers the cotton web together with the lower crushing roller. The working principle of the crushing roller and the stripping roller is as follows: Figure 1 As shown, the upper crushing roller 2 strips the cotton web from the stripping roller 1 and transfers it to the next mechanism together with the lower crushing roller 4.

[0003] The schematic diagram of the working structure of the crushing roller and the stripping roller used in the existing equipment is shown in the attached figure. Figure 2 , Figure 3 As shown, the position of the stripping roller 1 is fixed, the upper crushing roller bearing seat 3 drives the upper crushing roller 2 to rotate around the small shaft 5, and the minimum distance L between the stripping roller 1 and the upper crushing roller 2 is a fixed value, that is, the distance between the stripping roller 1 and the upper crushing roller 2 is fixed and cannot be adjusted. According to the diversification of textile raw materials and the variety of yarn counts in textile factories, some fibers are fluffy, some are not fluffy, sometimes the raw sliver is large in quantity, and sometimes the raw sliver is small in quantity. These phenomena will cause the cotton net on the stripping roller to be thick or thin. When the cotton web on the cotton stripping roller 1 is thicker, the upper crushing roller 2 can effectively and smoothly transfer the cotton web on the cotton stripping roller 1, but when the cotton web on the cotton stripping roller 1 is thinner and not too fluffy, the upper crushing roller 2 cannot effectively transfer the cotton web on the cotton stripping roller 1, which will cause the cotton stripping roller to return to the cotton web. In this case, the cotton web not only has holes, affecting the quality indicators of the raw strips, but also causes accumulation and hanging of cotton webs after the cotton stripping roller returns to the cotton web, which can easily cause damage to the needle clothing. Summary of the invention

[0004] The purpose of the present invention is to provide a device for adjusting the distance between the crushing roller and the stripping roller in view of the shortcomings of the above-mentioned prior art. The structure of the present invention can adjust the process distance between the upper crushing roller and the stripping roller according to the type of spinning and the quantitative size of the raw sliver.

[0005] The objective of the present invention is achieved through the following technical solutions:

[0006] The device for adjusting the distance between the crushing roller and the cotton stripping roller of the present invention comprises a cotton stripping roller and an upper crushing roller for transferring the cotton web on the cotton stripping roller, wherein the upper crushing roller is installed in bearing seats at both ends of the upper crushing roller, and the upper crushing roller bearing seats are installed on the frame in a manner of swinging around the axis; the crushing roller bearing seats are installed on the frame in a manner of swinging around the axis through a pin shaft and an eccentric sleeve mounted on the pin shaft for adjusting the distance between the upper crushing roller and the cotton stripping roller, and the eccentric sleeve forms a tight fit with the pin shaft through a nut and a locking nut.

[0007] The eccentric distance E of the eccentric sleeve in the present invention is 0.5 mm.

[0008] The beneficial effects of the present invention are as follows:

[0009] When the process distance between the upper crushing roller and the stripping roller needs to be adjusted, first loosen the nut and lock nut, then adjust the distance between the upper crushing roller and the stripping roller by adjusting (screwing) the eccentric sleeve, and tighten the nut and lock nut after the distance is adjusted appropriately. The present invention can adjust the crushing roller and the stripping roller to an appropriate distance when spinning different raw materials, improve the transfer rate of the crushing roller, and avoid the stripping roller from returning the flower and damaging the card clothing.

[0019] The present invention is further described below in conjunction with embodiments (attached drawings):

[0020] like Figure 4 , 5 As shown in Figures 6 and 7, the device for adjusting the distance between the crushing roller and the cotton stripping roller of the present invention comprises a cotton stripping roller 1, an upper crushing roller 2 for transferring the cotton net on the cotton stripping roller 1, the upper crushing roller 2 is installed in bearing seats 3 at both ends of the upper crushing roller, and the upper crushing roller bearing seats 3 are installed on the frame in a swinging manner around the axis; the crushing roller bearing seats 3 are installed on the frame in a swinging manner around the axis through a pin shaft 5 and an eccentric sleeve 6 mounted on the pin shaft for adjusting the distance between the upper crushing roller 2 and the cotton stripping roller 1, and the eccentric sleeve 6 forms a tight fit with the pin shaft 5 through a nut 7 and a locking nut 8.

[0021] The eccentric distance E of the eccentric sleeve 6 in the present invention is 0.5 mm.

[0022] The structural feature of the present invention is that the process distance between the upper crushing roller 2 and the stripping roller 1 is adjusted according to the type of spinning and the quantitative size of the raw sliver. When the process distance between the upper crushing roller 2 and the stripping roller 1 needs to be adjusted, the nut 7 and the locking nut 8 are first loosened, and then the distance between the upper crushing roller and the stripping roller is adjusted by adjusting (screwing) the eccentric sleeve 6. After the distance is adjusted appropriately, the nut and the locking nut are tightened. When the carding machine spins different raw materials, the crushing roller and the stripping roller can be adjusted to a suitable distance, the transfer rate of the crushing roller is improved, and the stripping roller is prevented from returning and damaging the card clothing.
