Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of carding processing, specifically a self-cleaning cotton stripping roller structure. Background Technology
[0002] In cotton spinning equipment, the roller is a crucial component, primarily used to peel the fiber layer from the doffer surface and transfer it to the rollers to form a fiber web. The stripping roller structure mainly consists of the stripping roller and the rollers. The stripping process relies on the cross-configuration of the needles and the synergistic effect of airflow. The doffer and the stripping roller needles form a gripping-release cycle; when the difference in linear velocity between the needles reaches a set threshold, the fiber layer is peeled and transferred. During the stripping process, the roller directly contacts and pulls the fiber web. As stripping proceeds, fibers and other impurities accumulate on the roller surface. These accumulated impurities are transported along with the fibers, leading to defects such as fiber breakage and clumping in subsequent processes, affecting the quality of the finished product. Therefore, self-cleaning is an indispensable part of the fiber web stripping process, ensuring product quality and the smooth operation of the production line.
[0003] The self-cleaning structure on existing roller devices generally uses a cleaning brush. The brush can contact the roller and remove residual fibers on the teeth through mechanical friction. However, the cleaning brush cannot identify the thickness of the fiber accumulation on the roller. The fixed distance between the cleaning brush and the roller means that if the distance is too large, the cleaning brush will not clean the roller completely. If the distance is too small, the needle cloth on the roller will be worn, which will affect the peeling efficiency of the peeling roller. Summary of the Invention
[0004] The purpose of this invention is to provide a self-cleaning cotton-removing roller structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A self-cleaning cotton stripping roller structure includes a mounting frame on which a doffer and a roller are rotatably mounted, and the doffer is controlled by a drive assembly mounted on the mounting frame. It also includes a cleaning mechanism mounted on the mounting frame, and both ends of the cleaning mechanism are connected to elastic members disposed on the mounting frame. When the cleaning mechanism cleans the roller, the elastic members can change the distance between the cleaning mechanism and the roller. An adjustable transmission component connects the roller and the cleaning mechanism respectively.
[0006] The self-cleaning stripping roller structure as described above: the drive assembly includes a motor mounted on the mounting bracket, the output shaft of the motor being connected to the doffer via a first toothed belt.
[0007] The self-cleaning cotton stripping roller structure described above: a drive shaft is rotatably mounted on the mounting bracket, the drive shaft is connected to the doffer via a second toothed belt, and the drive shaft is connected to the roller via a gear set.
[0008] The self-cleaning cotton stripping roller structure described above: a support plate is installed on the mounting frame, a groove is formed on the support plate, and a limiting sleeve with an annular structure is slidably disposed in the groove.
[0009] The self-cleaning cotton-removing roller structure described above: the elastic element includes an insert cylinder mounted on the support plate, an insert rod slidably disposed inside one end of the insert cylinder, and a connecting hoop that can be sleeved on the limiting sleeve is fixedly connected to the end of the insert rod away from the insert cylinder. It also includes a spring, which is disposed inside the plug-in cylinder, with one end of the spring abutting against the plug-in cylinder and the other end abutting against the plug-in rod.
[0010] The self-cleaning cotton stripping roller structure described above: the cleaning mechanism includes a cleaning roller, the axis of which coincides with the axis of the limiting sleeve, and the rotating shafts at both ends of the cleaning roller are rotatably connected to the limiting sleeve, and a plurality of brushes are formed on the cleaning roller.
[0011] The self-cleaning cotton stripping roller structure described above: the adjustable transmission component includes a central shaft, which is connected to the cleaning roller shaft and the roller shaft respectively via a first connecting rod and a second connecting rod, and the central shaft is connected to the roller shaft via a third toothed belt, and the central shaft is connected to the cleaning roller shaft via a fourth toothed belt.
[0012] The self-cleaning cotton stripping roller structure described above: a drive shaft is rotatably mounted on the mounting bracket, and the drive shaft is connected to the doffer and the roller via a first gear set and a second gear set.
[0013] Compared with the prior art, the beneficial effects of this utility model are: When the roller peels the fiber web from the doffer, the adjustable transmission component ensures that the cleaning mechanism always performs cleaning work on the roller. Under the action of the elastic component, the cleaning mechanism can automatically adjust the distance between itself and the roller, which can accurately match the degree of fiber accumulation. This avoids incomplete cleaning due to an excessively large fixed distance or wear of the needle cloth due to an excessively small fixed distance. This design can stably maintain the cleaning effect on the roller while reducing damage to the needle teeth on the roller surface. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Please see Figures 1-6 As an embodiment of the present utility model, the self-cleaning cotton stripping roller structure includes a mounting frame 1, on which a doffer 2 and a roller 3 are rotatably mounted respectively, and the doffer 2 is controlled by a drive assembly mounted on the mounting frame 1. It also includes a cleaning mechanism installed on the mounting frame 1, and both ends of the cleaning mechanism are connected to elastic members provided on the mounting frame 1. When the cleaning mechanism cleans the roller 3, the elastic members can change the distance between the cleaning mechanism and the roller 3. An adjustable transmission component connects the roller 3 and the cleaning mechanism respectively.
[0023] In this embodiment, the roller 3 and doffer 2 rotate synchronously by driving the drive assembly, and there is a difference in rotation speed between the roller 3 and the doffer 2. When the needle teeth on the roller 3 peel off the fiber web on the doffer 2, some fibers may remain on the surface of the roller 3 due to adhesion or insufficient tension. The cleaning mechanism cleans the roller 3 synchronously with the cotton peeling operation, removing the residual fibers on the needle teeth through mechanical friction, avoiding accumulation that affects the subsequent peeling efficiency. Under the action of the elastic element, the cleaning mechanism can autonomously adjust the distance between itself and the roller 3, which can accurately match the degree of fiber accumulation and avoid incomplete cleaning due to too large a fixed distance or wear of the needle cloth due to too small a fixed distance. This design can stably maintain the cleaning effect on the roller 3 while reducing damage to the needle teeth on the surface of the roller 3.
[0024] As a further embodiment of this utility model, please refer to... Figure 1 The drive assembly includes a motor 4 mounted on the mounting bracket 1, and the output shaft of the motor 4 is connected to the doffer 2 via a first toothed belt 5.
[0025] A drive shaft 9 is rotatably mounted on the mounting bracket 1. The drive shaft 9 is connected to the doffer 2 via a second toothed belt 7, and the drive shaft 9 is connected to the roller 3 via a gear set 8.
[0026] In this embodiment, when the motor 4 is driven to work, it drives the output shaft to rotate. Under the transmission action of the first toothed belt 5, it drives the doffer 2 to rotate. At the same time, with the cooperation of the second toothed belt 7 and the gear set 8, the roller 3 and the doffer 2 can rotate synchronously, with opposite rotation directions and different speeds, so that the needle teeth on the roller 3 can peel off the fiber web on the doffer 2 and avoid the fiber web on the doffer 2 from being too thick and accumulating.
[0027] As a further embodiment of this utility model, please refer to... Figure 5 The mounting bracket 1 is equipped with a support plate 22, and a sliding groove 2201 is formed on the support plate 22. A limiting sleeve 10 with an annular structure is slidably disposed in the sliding groove 2201.
[0028] The elastic element includes a plug-in cylinder 13 mounted on the support plate 22. A plug-in rod 12 is slidably disposed inside one end of the plug-in cylinder 13, and a connecting hoop 11 that can be sleeved on the limiting sleeve 10 is fixedly connected to the end of the plug-in rod 12 away from the plug-in cylinder 13. It also includes a spring 14, which is disposed inside the plug tube 13. One end of the spring 14 abuts against the plug tube 13, and the other end abuts against the plug rod 12.
[0029] In this embodiment, the spring 14 is always in a compressed state. When the fiber accumulation between two adjacent needle teeth on the roller 3 is too thick, the accumulated fiber will squeeze the cleaning mechanism when rotating, so that the limiting sleeve 10 slides relative to the slide groove 2201. The cleaning mechanism can make way for the roller 3, so as to avoid the distance between the cleaning mechanism and the roller 3 being too small. When the cleaning mechanism and the roller 3 rub against each other, the needle cloth on the roller 3 will be damaged.
[0030] As a further embodiment of this utility model, please refer to... Figure 3 The cleaning mechanism includes a cleaning roller 6, the axis of which coincides with the axis of the limiting sleeve 10, and the rotating shafts at both ends of the cleaning roller 6 are rotatably connected to the limiting sleeve 10. A plurality of brushes 601 are formed on the cleaning roller 6.
[0031] In this embodiment, the gear set 8 is configured such that the cleaning roller 6 and the roller 3 rotate in opposite directions and have different speeds. When the cleaning roller 6 and the roller 3 rotate simultaneously, the brush 601 generates mechanical friction against the needle teeth on the roller 3. Under the action of the spring 14, the contact pressure of the brush 601 on the needle cloth always maintains a stable contact force, avoiding incomplete cleaning due to excessive fixed spacing or wear of the needle cloth due to insufficient fixed spacing.
[0032] It should be noted that: the mounting frame 1 is provided with a collection trough 20, which is located at the lower end of the cleaning roller 6, so that the brush 601 can throw the cleaned fibers into the collection trough 20. The mounting frame 1 is also provided with a negative pressure pump, which is connected to the collection trough 20 through the delivery pipe 21, so that the cleaned fibers can be transferred in time.
[0033] As a further embodiment of this utility model, please refer to... Figure 5 The adjustable transmission component includes a central shaft 15, which is connected to the rotating shaft of the cleaning roller 6 and the transmission shaft 9 via a first connecting rod 16 and a second connecting rod 17, respectively. The central shaft 15 is connected to the transmission shaft 9 via a third toothed belt 18 and to the rotating shaft of the cleaning roller 6 via a fourth toothed belt 19.
[0034] In this embodiment, when the cleaning roller 6 cleans the roller 3, if the position of the cleaning roller 6 changes, the position of the central shaft 15 can be adjusted under the adjustment of the first connecting rod 16 and the second connecting rod 17, so that the cleaning roller 6 and the transmission shaft 9 always maintain a stable transmission state. When the distance between the cleaning roller 6 and the roller 3 is automatically adjusted, it does not affect the cleaning work of the cleaning roller 6 on the roller 3.
[0035] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
