Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning rollers for sound insulation cotton production, and in particular relates to a roller shaft cotton material cleaning roller pick-and-place support mechanism. Background Technology

[0002] The production of automotive sound insulation cotton mainly involves: opening and mixing the fiber raw materials, then carding them into a web using carding machine rollers, and then cross-laying them to the required thickness. Next, the fiber web is thermally bonded and formed under temperature and pressure using hot press rollers. Finally, the cotton felt is cooled, cut, and wound onto rollers or stacked to complete the process.

[0003] In the aforementioned production process, cotton cleaning rollers play a crucial maintenance role. These are rotating rollers, typically covered with special bristles, scrapers, or adhesive materials, designed to automatically and efficiently remove residual cotton fibers adhering to or entangled on the surfaces of various processing rollers. Their core function is continuous online cleaning, preventing cotton buildup from affecting equipment operation, product quality, or causing downtime. These cleaning rollers are widely used in several key stages of sound insulation cotton production lines, including but not limited to: the input / output rollers of opening and mixing equipment, the cylinder and doffer rollers of the carding machine, the conveyor rollers for precision fiber web laying in the web-laying machine, and the winding rollers that ultimately wind the formed cotton felt into rolls. Deploying cotton cleaning rollers on these rollers significantly improves the efficiency of continuous equipment operation and ensures the cleanliness and consistency of the surface and structure of the sound insulation cotton product.

[0004] However, existing cleaning rollers, after installation, directly contact the roller shaft to be cleaned by gravity. But the cotton fibers require a certain amount of tension during cleaning, and the free state of the cleaning roller will cause radial displacement, which makes it impossible to clean the cotton fibers from the roller shaft, or requires more rolling cycles to clean them completely, affecting the cleaning effect. Secondly, traditional cleaning rollers lack axial limiting, and in actual use, the uneven thickness of the cotton fibers on both sides of the cleaning roller will cause tilting and displacement.

[0005] To address the aforementioned issues, this application proposes a roller-type cotton material cleaning roller pick-and-place support mechanism. Utility Model Content

[0006] The purpose of this invention is to provide a roller support mechanism for picking up and placing cotton cleaning rollers, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a roller support mechanism for picking up and placing cotton cleaning rollers, comprising two support plates forming support at both ends of the cleaning roller. Each support plate includes a rotating groove for supporting the shaft of the cleaning roller and a picking and placing port. A sliding locking plate is provided on the side of one of the support plates, and a limiting strip is formed at the front end of the locking plate. A shaft is fixed on the cleaning roller, and an annular groove is formed in the shaft to radially engage with the limiting strip. The engagement of the limiting strip with the annular groove simultaneously restricts the radial and axial degrees of freedom of the cleaning roller between the two support plates.

[0009] Furthermore, guide plates and locking plates are fixed to the inner and outer sides of the connecting support plate in a horizontal sliding fit, and locking seats and limiting strips are also fixed to the inner and outer sides of the support plate in an insert fit.

[0010] Furthermore, a bracket is fixed to one side of the locking plate, and both the bracket and the locking plate are provided with locking holes. A sliding locking pin is provided in the locking hole, and a through hole is provided on the support plate to engage with the locking pin.

[0011] Furthermore, a support plate is fixed in the area between the locking pin and the support plate, and a spring is provided between the support plate and the support to abut against it, so that the locking pin is inserted into the through hole by means of the spring.

[0012] Furthermore, a handle is fixed to one end of the locking pin.

[0013] Furthermore, the guide plate and the lock seat are all fixed to the support plate by bolts, and the support plate is provided with connecting holes that cooperate with the guide plate and the lock seat.

[0014] This utility model has the following beneficial effects:

[0015] This utility model can radially limit the shaft in the rotating groove by setting a limiting strip at the front end of the locking plate, thereby preventing the cleaning roller from jumping and thus cleaning the cotton fibers on the surface of the roller in time. At the same time, the end of the cleaning roller away from the limiting strip is set as a free end. Due to the restriction of the other end by the limiting strip, the free end will also be unable to jump due to the presence of the limiting strip. In other words, the limiting strip can overcome the jumping of the cleaning roller.

[0016] This invention, by setting a limiting strip that engages with the annular groove, can limit the axial displacement of the cleaning roller after installation, thereby avoiding axial displacement caused by the thickness difference of the cotton fibers collected on the cleaning roller and ensuring the cleaning effect of the cotton fibers on the roller shaft.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Please see Figures 1-5 As shown, this utility model is a roller cotton cleaning roller pick-and-place support mechanism, including two support plates 1 forming support at both ends of the cleaning roller 6. The support plates 1 are fixed to the fixing frame of the sound insulation cotton production equipment by bolts, so that the surface of the cleaning roller 6 is in contact with the roller shaft to be cleaned. In actual use, the surface of the cleaning roller 6 is provided with lint-sticking paper, barbed structure, etc., which can remove the cotton fibers on the surface of the roller shaft and retain them on the surface of the cleaning roller 6 after contacting the roller shaft. The support plate 1 includes a rotating groove 11 for supporting the shaft 61 on the cleaning roller 6 and a pick-and-place port 12. More specifically, in order to prevent the shaft 61 from falling off, the pick-and-place port 12 is located in the middle of the rotating groove 11.

[0029] Furthermore, a sliding locking plate 2 is provided on the side of one support plate 1. A limiting strip 21 is formed at the front end of the locking plate 2. A shaft 61 is fixed on the cleaning roller 6. An annular groove 62 is opened in the shaft 61 to radially engage with the limiting strip 21. In order to facilitate the insertion of the limiting strip 21, the width of the annular groove 62 is greater than the thickness of the limiting strip 21. The radial and axial degrees of freedom of the cleaning roller 6 between the two support plates 1 are restricted by the engagement of the limiting strip 21 and the annular groove 62. The other support plate 1 does not have a locking plate 2. The operation end of the cleaning roller 6 is located on one side of the locking plate 2. The other end does not have a locking plate 2 to engage with the support plate 1. During operation, the operator does not need to walk between the two ends, which simplifies the installation and disassembly steps and also increases the installation reliability of the cleaning roller 6 on the support plate 1.

[0030] Specifically, guide plates 3 and locking plates 2 are fixed to the inner and outer sides of the connecting support plate 1 and slide horizontally. Locking seats 4 and limiting strips 21 are also fixed to the inner and outer sides of the support plate 1. More specifically, after the guide plates 3 and the support plate 1 are connected, a horizontal sliding space for the locking plate 2 is formed between them. After the locking seats 4 and the support plate 1 are connected, a slot for the insertion of the limiting strips 21 is formed. All of these are used to ensure the structural stability after the limiting strips 21 are inserted into the annular groove 62 and to restrict the axial and radial degrees of freedom.

[0031] Furthermore, the guide plate 3 and the lock seat 4 are both fixed to the support plate 1 by bolts. The support plate 1 is provided with connecting holes that cooperate with the guide plate 3 and the lock seat 4. With the support plate 1 as the two symmetrical guide plates 3 or lock seats 4, after the bolts pass through the two guide plates 3 or lock seats 4 and the support plate 1, they are locked with nuts. One bolt structure can press and fix the two symmetrical guide plates 3 or lock seats 4, which is convenient for disassembly and assembly.

[0032] Specifically, a bracket 22 is fixed on one side of the locking plate 2. Both the bracket 22 and the locking plate 2 are provided with locking holes 24. A sliding locking pin 23 is provided in the locking hole 24. A through hole 13 is provided on the support plate 1 to be inserted and engaged with the locking pin 23.

[0033] Furthermore, a support plate 231 is fixed in the area between the bracket 22 and the support plate 1. A spring 5 is provided between the support plate 231 and the bracket 22 to abut against it. The spring 5 causes the locking pin 23 to be inserted into the through hole 13. In this embodiment, when the spring 5 is compressed to its minimum state, the front end of the locking pin 23 is completely disengaged from the through hole 13, but it will not completely disengage from the locking hole 24 on the side close to the bracket 22, ensuring reliable use of the structure.

[0034] Furthermore, to facilitate the axial pulling of the locking pin 23, a handle 232 is fixed to one end of the locking pin 23. In this embodiment, when installing the locking pin 23, the support plate 231 is first welded to the locking pin 23, and then the locking pin 23 is passed through the locking hole 24. The spring 5 is sleeved on the outside of the locking pin 23 and abuts against the support plate 231. The bracket 22 is sleeved on the other end of the locking pin 23 and contacts the outside of the support plate 1. Welding is performed at the connection between the bracket 22 and the support plate 1 to complete the assembly work.

[0035] It is understood that by setting a limiting strip at the front end of the locking plate, this utility model can both insert into the annular groove to limit the axial displacement of the cleaning roller and prevent movement caused by uneven accumulation of cotton fibers; and also limit the radial position of the shaft in the rotating groove, effectively suppressing the overall jumping of the cleaning roller, thereby ensuring a stable cleaning effect of cotton fibers on the roller surface.

[0036] One specific application of this embodiment is as follows: Figure 1-2 The image shows the cleaning roller 6 mounted between two support plates 1. The limiting strip 21 is located in the locking seat 4, and the locking pin 23 passes through the locking hole 24. At this time, the surface of the cleaning roller 6 is in contact with the roller shaft to be cleaned. After the roller shaft rotates, the cotton fibers are collected on the cleaning roller 6.

[0037] Cleaning the cleaning roller 6: Hold the handle 232 and pull the locking pin 23 outward until it is disengaged from the through hole 13. The spring 5 is compressed. Then move the locking plate 2 to the side. The limiting strip 21 is disengaged from the locking seat 4 and the shaft 61 and moves to the side of the rotating groove 11. After lifting the cleaning roller 6 upward, take the shaft 61 outward along the pick-up and drop-off port 12 and clean the cotton fibers collected on the surface of the cleaning roller 6.

[0038] Installation of cleaning roller 6: The shaft 61 is placed in the rotating groove 11 through the pick-and-place port 12. The locking plate 2 is slid in the opposite direction so that the limiting strip 21 passes through the shaft 61 and is inserted into the locking seat 4. After the locking pin 23 is released, it is inserted into the through hole 13 under the action of the spring 5 and locked. The cleaning roller 6 restricts axial and radial movement on the support plate 1, but does not affect the circumferential freedom of the cleaning roller 6.
