Description

Technical Field

[0001] The utility model relates to the technical field of equipment cleaning, in particular to a cleaning device for a rubber roller of a rubber rolling machine. Background Art

[0002] As people's living standards improve, the requirements for car interiors are also increasing, among which the proportion of soft material interiors is gradually increasing. The representative product of soft material interiors is the upper trim, which is generally composed of three parts of leather, flexible material and injection molded frame, and each layer of material needs to be bonded with hot melt adhesive.

[0003] Hot melt adhesive is generally attached to the surface of the material through spraying or rolling. Among them, the hot melt adhesive rolling process has the advantages of high production efficiency, high glue utilization rate and low pollution, and its application range is becoming more and more extensive. At the same time, the hot melt adhesive rolling process has very high requirements on the cleanliness of the rubber roller surface, and the glue on the rubber roller surface needs to be cleaned regularly.

[0004] The current method for cleaning the rubber roller is as follows: Step 1, first use a silicone plate to remove excess glue; Step 2, then adjust the gap between the rubber coating roller and the rubber scraping roller to 0-0.1mm, add liquid glue remover between the rubber coating roller and the rubber scraping roller, and heat the rubber coating roller and the rubber scraping roller for 5 minutes; Step 3, increase the gap between the rubber coating roller and the rubber scraping roller, and the liquid glue remover flows to the lower pad and the rag under the action of gravity; Step 4, wipe the two rubber rollers with a rag.

[0005] The existing cleaning method has the following problems when adjusting the gap between the glue coating roller and the glue scraping roller in step 2: when the gap is small, the glue roller is subjected to excessive force, which damages the surface layer or transmission parts of the glue coating roller and the glue scraping roller; when the gap between the glue coating roller and the glue scraping roller is too large, the liquid glue remover leaks, causing waste of the glue remover and affecting the glue removal effect; the problem in step 3 is that a large amount of rags are used, resulting in a large amount of garbage mixed with the glue remover, and the processing cost is high.

[0006] Therefore, it is necessary to provide a cleaning device for the rubber roller of a rubber rolling machine to avoid adjusting the gap between the rubber rollers to an excessively small value, while reducing the amount of the degumming agent used and improving the use efficiency of the degumming agent. Utility Model Content

[0007] In view of the technical problems existing in the background technology, this utility model patent provides a cleaning device for the rubber roller of a rubber rolling machine. The use of the cleaning device makes the cleaning efficiency higher and the cleaning operation simpler, while avoiding damage to the rubber coating roller, rubber scraping roller and transmission parts.

[0008] To achieve the above-mentioned purpose, the utility model provides a cleaning device for the rubber roller of a rubber rolling machine, comprising: a rubber coating roller cleaning sub-device and a rubber scraping roller cleaning sub-device, the midlines of which are parallel and connected to each other at the sides, corresponding to the axially parallel rubber coating roller and the rubber scraping roller;

[0009] The glue coating roller cleaning sub-device comprises a first frame and a first glue remover containing tank, and the glue scraping roller cleaning sub-device comprises a second frame and a second glue remover containing tank;

[0010] The first frame and the second frame are both rectangular parallelepiped structures with open upper sides, and the first adhesive remover containing groove and the second adhesive remover containing groove are respectively arranged in the first frame and the second frame;

[0011] Concave arc grooves are arranged in the middle of the first adhesive remover containing groove and the second adhesive remover containing groove, respectively corresponding to the axial outer circumferential arc surfaces of the adhesive coating roller and the adhesive scraping roller.

[0012] As a further improvement of the present invention, the edge of the first degumming agent containing groove is fully connected to the inner wall of the first frame by welding, and the edge of the second degumming agent containing groove is fully connected to the inner wall of the second frame by welding.

[0013] As a further improvement of the present invention, inclined plates are provided on both sides of the arc groove of the first debonding agent containing groove, and the inclined plates are inclined from bottom to top from the edge of the arc groove to the inner wall of the first frame.

[0014] As a further improvement of the present invention, inclined plates are provided on both sides of the arc groove of the second debonding agent containing groove, and the inclined plates are inclined from bottom to top from the edge of the arc groove to the inner wall of the second frame.

[0015] As a further improvement of the present invention, the length of the first frame along the centerline direction is greater than the axial length of the glue coating roller, and the width of the first frame is greater than the cross-sectional diameter of the glue coating roller.

[0016] As a further improvement of the present invention, the length of the second frame along the central direction is greater than the axial length of the scraping roller, and the width of the second frame is greater than the cross-sectional diameter of the scraping roller.

[0017] As a further improvement of the present invention, corresponding to the height difference in the structures of the glue coating roller and the glue scraping roller, a height difference is set between the first glue remover containing groove and the second glue remover containing groove.

[0018] As a further improvement of the utility model, the outer side wall of the glue coating roller cleaning sub-device and / or the glue scraping roller cleaning sub-device is provided with a positioning block, and a limiting block or a limiting groove is provided at the placement position of the cleaning device corresponding to the positioning block. The positioning block cooperates with the limiting block or the limiting groove to make the glue coating roller cleaning sub-device and the glue scraping roller cleaning sub-device parallel to the axial direction of the glue coating roller and the glue scraping roller.

Furthermore, compared with the existing technology, the glue remover flowing down from the glue coating roller and the glue scraping roller is caught by a rag, which also greatly reduces the amount of rag used, thereby reducing the amount of garbage generated, and is safer and more environmentally friendly.

[0022] In the utility model, the glue coating roller and the glue scraping roller contact the glue remover in the first glue remover containing groove and the second glue remover containing groove when they rotate, so that the outer periphery of the glue coating roller and the glue scraping roller can be evenly dipped with the glue remover. Compared with the situation where people manually sprinkle the glue remover on the surface of the glue coating roller and the glue scraping roller, the utility model also greatly improves the cleaning efficiency of the glue removing roller and the glue scraping roller.

[0023] The arc groove of the first degumming agent containing groove and the arc groove of the second degumming agent containing groove in the utility model control the amount of degumming agent used, and also take into account the collection function of the degumming agent after cleaning, so that the degumming agent can be repeatedly used, which greatly reduces the use cost.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0031] The utility model is further described in detail below in conjunction with the accompanying drawings:

[0032] like Figure 1 As shown, the utility model provides a cleaning device for the rubber roller of a rubber rolling machine, comprising: a rubber coating roller 3 cleaning sub-device 1 and a rubber scraping roller 4 cleaning sub-device 2, the midlines of which are parallel and connected to each other and which are arranged corresponding to the axially parallel rubber coating roller 3 and the rubber scraping roller 4;

[0033] The cleaning sub-device 1 of the glue coating roller 3 includes a first frame 11 and a first glue removing agent containing tank 12, and the cleaning sub-device 2 of the glue scraping roller 4 includes a second frame 21 and a second glue removing agent containing tank 22;

[0034] The first frame 11 and the second frame 21 are both rectangular structures with open upper sides, and can be welded from 2 mm thick stainless steel plates. The first degumming agent holding tank 12 and the second degumming agent holding tank 22 can be bent from 1 mm thick stainless steel plates, and are respectively arranged in the first frame 11 and the second frame 21. The first frame 11 and the second frame 21 are respectively used to support the first degumming agent holding tank 12 and the second degumming agent holding tank 22, and the first degumming agent holding tank 12 and the second degumming agent holding tank 22 are both used to hold degumming agents;

[0035] Concave arc grooves A are set in the middle of the first glue remover containing groove 12 and the second glue remover containing groove 22 corresponding to the axial outer arc surfaces of the glue coating roller 3 and the glue scraping roller 4, respectively, which can better adapt to the glue coating and glue scraping rollers 4 in a rotating state, so that the glue coating roller 3 and the glue scraping roller 4 can rotate to dip the glue remover, and the glue remover reacts with the glue on the surface of the glue coating roller 3 and the glue scraping roller 4 to achieve a cleaning effect on the glue.

[0036] in,

[0037] The edge of the first degumming agent containing groove 12 is fully welded to the inner wall of the first frame 11, and the edge of the second degumming agent containing groove 22 is fully welded to the inner wall of the second frame 21 to prevent the degumming agent from leaking.

[0038] Inclined plates B are provided on both sides of the circular arc groove A of the first degumming agent containing groove 12, and the inclined plates B are inclined from bottom to top from the edge of the circular arc groove A to the inner wall of the first frame 11. When the degumming agent flows down from the surface of the glue coating roller 3 and falls on the inclined plates B of the first degumming agent containing groove 12, the degumming agent can slide down along the inclined plates B into the circular arc groove A, which is convenient for collecting and reusing the degumming agent.

[0039] Inclined plates B are provided on both sides of the circular arc groove A of the second degumming agent containing groove 22, and the inclined plates B are inclined from bottom to top from the edge of the circular arc groove A to the inner wall of the second frame 21. When the degumming agent flows down from the surface of the scraper roller 4 and falls on the inclined plates B of the second degumming agent containing groove 22, the degumming agent can slide down along the inclined plates B into the circular arc groove A, which is convenient for collecting and reusing the degumming agent.

[0040] The length of the first frame 11 along the centerline direction is greater than the axial length of the glue coating roller 3, and the width of the first frame 11 is greater than the cross-sectional diameter of the glue coating roller 3, so that the glue coating roller 3 can be completely located above and inside the first frame 11, preventing the glue remover flowing down from the glue coating roller 3 from falling outside the first frame 11, causing additional cleaning work.

[0041] The length of the second frame 21 along the center direction is greater than the axial length of the scraper roller 4, and the width of the second frame 21 is greater than the cross-sectional diameter of the scraper roller 4, so that the scraper roller 4 can be completely located above and inside the second frame 21, preventing the glue remover flowing down from the scraper roller 4 from falling outside the second frame 21, causing additional cleaning work.

[0042] Since the glue coating roller 3 and the glue scraping roller 4 have a height difference in design structure when adapting to the use scenario, in order to adapt to the height difference in design structure of the glue coating roller 3 and the glue scraping roller 4, the height difference between the first glue removing agent holding groove 12 and the second glue removing agent holding groove 22 corresponding to the height difference in structure of the glue coating roller 3 and the glue scraping roller 4 is also provided, such as Figure 1 shown.

[0043] Further, such as Figure 1 , 2As shown, a positioning block 5 is provided on the outer side wall of the cleaning sub-device 1 of the glue coating roller 3 and / or the cleaning sub-device 2 of the glue scraping roller 4, and a limiting block or a limiting groove is provided at the placement position of the cleaning device corresponding to the positioning block 5. The positioning block 5 cooperates with the limiting block or the limiting groove to make the cleaning sub-device 1 of the glue coating roller 3 and the cleaning sub-device 2 of the glue scraping roller 4 axially parallel to the glue coating roller 3 and the glue scraping roller 4, and further, make the axis of the glue coating roller 3 and the glue scraping roller 4 parallel to the center line of the first degumming agent containing groove 12 and the second degumming agent containing groove 22.

[0044] The axis of the glue coating roller 3 corresponds to the line connecting the lowest points of the arc groove A of the first glue removing agent containing groove 12, and the axis of the glue scraping roller 4 corresponds to the line connecting the lowest points of the arc groove A of the second glue removing agent containing groove 22, so that the glue coating roller 3 can rotate at equal intervals in the arc groove A of the first glue removing agent containing groove 12 and evenly dip the glue removing agent, and the glue scraping roller 4 can rotate at equal intervals in the arc groove A of the second glue removing agent containing groove 22 and evenly dip the glue removing agent.

[0049] Step 3, place a cleaning device under the lifted glue removal roller and the glue scraping roller 4, so that the cleaning sub-device 1 of the glue coating roller 3 is located under the glue coating roller 3, and the cleaning sub-device 2 of the glue scraping roller 4 is located under the glue scraping roller 4, and at the same time, the positioning block 5 is matched and fixed with the limit block at the placement position of the cleaning device;

[0050] Step 4, lower the glue removal roller and the glue scraping roller 4 to a height of 12 mm at the same time, so that the lowest points of the glue removal roller and the glue scraping roller 4 are respectively immersed in the glue removal agent in the first glue removal agent holding tank 12 and the second glue removal agent holding tank 22 for more than 5 mm, and do not contact the first glue removal agent holding tank 12 and the second glue removal agent holding tank 22;

[0051] Step 5: Heat and rotate the glue coating roller 3 and the glue scraping roller 4, so that the glue coating roller 3 and the glue scraping roller 4 rotate relative to each other in a normal working state (such as Figure 1 As shown), continue for 5 minutes to clean the glue remaining on the glue coating roller 3 and the glue scraping roller 4;

[0052] Step 6: Raise the adhesive removal roller and the adhesive scraping roller 4 to a height of 50 mm again;

[0053] Step 7, remove the cleaning device from under the glue coating roller 3 and the glue scraping roller 4;

[0054] Step 8: Use a rag to wipe off the residual glue remover on the surface of the glue coating roller 3 and the glue scraping roller 4 to complete the cleaning of the glue coating roller 3 and the glue scraping roller 4.

[0056] Compared with the existing method in which the gap between the glue coating roller and the glue scraping roller is adjusted, which easily causes the gap to be too small and thus damages the nominal value of the glue roller or transmission parts, the utility model does not need to adjust the gap between the glue coating roller and the glue scraping roller, thereby avoiding damage to the surface of the glue coating roller and the glue scraping roller and the transmission parts; at the same time, the utility model collects the glue remover flowing down from the glue coating roller and the glue scraping roller by arranging the first glue remover containing groove and the second glue remover containing groove, thereby greatly reducing the amount of glue remover used, and the collected glue remover can be reused, thereby improving the use efficiency of the glue remover. Furthermore, compared with the existing technology, the glue remover flowing down from the glue coating roller and the glue scraping roller is caught by a rag, which also greatly reduces the amount of rag used, thereby reducing the amount of garbage generated, and is safer and more environmentally friendly.

[0057] In the utility model, the glue coating roller and the glue scraping roller contact the glue remover in the first glue remover containing groove and the second glue remover containing groove when they rotate, so that the outer periphery of the glue coating roller and the glue scraping roller can be evenly dipped with the glue remover. Compared with the situation where people manually sprinkle the glue remover on the surface of the glue coating roller and the glue scraping roller, the utility model also greatly improves the cleaning efficiency of the glue removing roller and the glue scraping roller.
