Description

Technical Field

[0001] The utility model relates to the technical field of leather production, in particular to a leather processing device. Background Art

[0002] Polyvinyl chloride (PVC) leather, also known as PVC leather, is a common synthetic leather. It typically consists of a base fabric as a support structure and a PVC layer that simulates natural leather. PVC leather is widely used in various industries due to its excellent wear and corrosion resistance, ease of cleaning, and ease of processing.

[0003] However, due to the poor air permeability of the PVC layer, and in order to improve its comfort in furniture such as seats and sofas, it will be punched during the production process of PVC leather.

[0004] For example, cardboard is first placed underneath the PVC leather as punching support and cushioning, and then the PVC leather is punched. During this process, the PVC layer and the base fabric will each produce and retain particles, and the cardboard will also produce a certain amount of paper scraps. At the same time, the edges of the small holes in the base fabric are more prone to burrs. Typically, the operator uses an air gun to manually blow away particles, paper scraps, and other residues from the surface of the PVC leather, finally forming the finished perforated leather, which is then collected into large rolls.

[0005] However, firstly, manual blowing with an air gun cannot remove the burrs on the base fabric, resulting in a poor appearance of the base fabric and affecting the product experience; secondly, manual blowing with an air gun is also difficult to completely remove the PVC layer, particles on the base fabric and paper scraps on the cardboard, resulting in a poor appearance and affecting the processing quality. Utility Model Content

[0006] The purpose of the utility model is to solve the problem that the traditional cleaning method after leather punching is not effective. The utility model provides a leather processing device that can remove various types of waste that may be generated after leather punching to a large extent, with good cleaning effect and high efficiency.

[0007] To solve the above technical problems, an embodiment of the present invention discloses a leather processing device for cleaning leather after punching, the leather processing device comprising: a frame; at least one scraper roller, provided on the frame and extending along a first direction, each of the scraper rollers comprising a plurality of cutter heads, the plurality of cutter heads being used to rotate relative to the surface of the leather; at least one brush roller, provided on the frame and extending along the first direction, the outer surface of each brush roller being provided with a plurality of bristles, the plurality of bristles being used to rotate relative to the surface of the leather; a blowing mechanism, provided on the frame; wherein, along the processing direction of the leather processing device, the at least one scraper roller, the at least one brush roller and the blowing mechanism are arranged in sequence at intervals; further comprising: a first waste receiving portion, provided on the frame, along the second direction, the first waste receiving portion being located at the bottom of the at least one scraper roller and the at least one brush roller, and being arranged toward the at least one scraper roller and the at least one brush roller; a second waste receiving portion, provided on the frame, along the second direction, the second waste receiving portion being located at the bottom of the blowing mechanism, and being arranged toward the blowing mechanism; the second direction intersects with the first direction.

[0008] Leather (such as PVC leather) usually includes a PVC layer and a base cloth. For example, after the leather is punched, particles are more likely to remain on the surface of the PVC layer and the base cloth. Moreover, when punching the leather, a cardboard for support needs to be added underneath it, which may also produce a certain amount of paper scraps. For this, the operator is usually required to use an air gun to manually blow it away. On the one hand, it is difficult to completely remove the particles, which affects the appearance of the product. On the other hand, the labor cost is high and the blowing operation efficiency is low. Secondly, the base cloth is more likely to produce burrs or burr adhesions after punching, which not only affects the appearance of the product, but also the burrs are prone to accumulate dust, making the product difficult to clean and maintain, and may even scratch the user. In addition, after the burrs are removed, a certain amount of dander will be produced, which is difficult to be blown away by an air gun.

[0009] Based on this, the above technical solution is adopted to sequentially arrange a scraper roller, a brush roller and a blowing mechanism in the processing direction of the leather processing device, which can remove burrs, particles, hair scraps, paper scraps and other waste materials remaining after leather punching to a large extent.

[0010] Specifically, at least one scraper roller is first used to scrape the leather surface. For example, the scraper roller is in close contact with the surface of the base fabric to scrape off burrs on the base fabric; for another example, during this process, some residual particles and paper scraps are also scraped off.

[0011] At least one brush roller is then used to brush the leather surface. For example, the brush roller can be placed in close contact with the surface of the base fabric to remove lint from the burrs removed by the scraper roller. Alternatively, the brush roller can further remove some residual particles and paper scraps. Finally, a strong airflow from a purge mechanism is used to completely remove lint, particles, and paper scraps from the leather.

[0012] Furthermore, the first waste receiving part in the leather processing device can accommodate waste removed by the scraper roller and the brush roller, and the second waste receiving part can accommodate waste blown away by the blowing mechanism, thereby improving the efficiency of waste collection and processing and reducing environmental pollution.

[0013] Therefore, in the leather processing device of the embodiment of the present application, the scraper roller, brush roller and blowing mechanism cooperate with each other to thoroughly remove the waste left on the surface of the leather after punching, avoiding the situation where manual air gun blowing is incomplete and the air gun cannot remove burrs. The cleaning effect is better, and the problems of poor leather appearance and high scrap rate are completely solved. The degree of automation is high, the leather processing efficiency is improved, and it is green and environmentally friendly.

[0014] According to another specific embodiment of the present invention, each scraper roller also includes a roller core extending along the first direction, the roller core is a polyhedron, and each of the blade heads is respectively arranged to fit the roller core in a direction parallel to each plane in the roller core.

[0015] According to another specific embodiment of the present invention, the blowing mechanism includes an air knife extending along the first direction, the air knife including an air outlet and multiple air inlets, the air outlet facing the leather, and the multiple air inlets spaced apart along the first direction. According to another specific embodiment of the present invention, the leather processing device further includes a fan connected to the multiple air inlets of the blowing mechanism.

[0016] Using the above technical solution, the blowing mechanism includes an air knife, which is provided with wind energy by a fan (for example, a high-pressure fan). Compared with a traditional air gun using compressed air, the cost of the air knife in the embodiment of the present application is lower.

[0017] According to another specific embodiment of the present invention, the leather processing device further includes: a purge chamber, the purge chamber is provided in the frame, and the purge mechanism is provided inside the purge chamber.

[0018] According to another specific embodiment of the present invention, along the second direction, a first inspection window is provided on one side of the purge chamber, and the first inspection window faces the purge mechanism. A first opening is provided on the other side of the purge chamber, and the first opening faces and corresponds to the second waste receiving part.

[0019] According to another specific embodiment of the present invention, the first waste receiving part includes, in sequence along the second direction and away from the scraper roller and the brush roller: a chip plate group, which is arranged on the frame, and the chip plate group defines a first receiving cavity, and along the first direction and the third direction, the first receiving cavity corresponds to the at least one scraper roller and the at least one brush roller; the third direction intersects with the second direction; a chip collecting bucket, one end of the chip collecting bucket is connected to the first receiving cavity, and the other end of the chip collecting bucket has a second opening; a first chip collecting box, which is defined with a second receiving cavity, and the second opening of the chip collecting bucket corresponds to the second receiving cavity; a tray, the two ends of the tray along the first direction are respectively fixed to the frame, and the first chip collecting box is arranged on the tray.

[0020] According to another specific embodiment of the present invention, the second waste receiving part includes: a second waste collecting box, which is arranged on the frame body, and the second waste collecting box defines a third receiving cavity, and the third receiving cavity corresponds to the first opening of the purge chamber.

[0021] According to another specific embodiment of the present invention, the leather processing device also includes: a plurality of first pressure rollers, which are used to make the leather pass through: the at least one scraper roller, the at least one brush roller, the blowing mechanism in sequence, and be transported to an external device by the blowing mechanism.

[0037] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0038] For the convenience of subsequent description, before describing the specific structure of the leather processing device, the embodiment of the present application first exemplarily defines the X direction, Y direction and Z direction. Figures 1 to 3 As shown, the Y direction is the length of the leather processing device when it is normally placed; the X direction is the width of the leather processing device when it is normally placed, which can also be understood as the cleaning processing direction of the leather processing device; and the Z direction is the height of the leather processing device when it is normally placed. The X, Y, and Z directions intersect with each other. The following explanation uses the example of the X, Y, and Z directions being perpendicular to each other.

[0039] refer to Figures 1 to 3 An embodiment of the present application provides a leather processing device for cleaning leather after punching, comprising a frame 100, two scraper rollers 200, a brush roller 300, a blowing mechanism 400, a first waste receiving part 500 and a second waste receiving part 600.

[0040] The frame 100 is the supporting frame of the leather processing device of the embodiment of the present application, and is used to support the aforementioned scraper roller 200, brush roller 300, purge mechanism 400, first waste receiving portion 500, and second waste receiving portion 600. The embodiment of the present application does not impose any specific restrictions on the shape, structure, or material of the frame 100; any material capable of supporting the aforementioned components falls within the scope of protection of the embodiment of the present application.

[0041] at the same time, Figures 1 to 3 Two scraper rollers 200, one brush roller 300 and one purge mechanism 400 are shown by way of example, but the embodiment of the present application does not impose any specific restrictions on the number of the three. For example, one, three, five or the like scraper rollers 200, two, three, four or the like brush rollers 300, and two, four, five or the like purge mechanisms 400 may be provided.

[0042] Furthermore, the leather processing device according to the embodiment of the present application includes a cleaning area A1 and a material receiving area A2 provided in the frame 100 .

[0043] The cleaning area A1 is used to clean the surface of the leather after the punching operation. The cleaning area A1 includes the two scraper rollers 200, the brush roller 300 and the blowing mechanism 400 mentioned above. That is, the leather (such as PVC leather) can be scraped, brushed and blown in the cleaning area A1.

[0044] For example, the scraper roller 200 can scrape off burrs generated during the previous punching of the leather base cloth, or can scrape off particles remaining on the PVC layer and / or base cloth of the leather after punching, or can scrape off paper scraps remaining on the cardboard required for punching, or the scraper roller 200 can scrape off burrs, particles, and paper scraps.

[0045] For example, the brush roller 300 can further brush away the hair scraps produced after the burrs on the leather base cloth are scraped away by the scraper roller 200, or can brush away the residual particles of the PVC layer of the leather and / or the base cloth that have not been scraped away by the scraper roller 200, or can also brush away the paper scraps remaining on the cardboard required for punching, or the brush roller 300 can brush away both hair scraps and particles and paper scraps.

[0046] For example, the blowing mechanism 400 can further blow the leather surface cleaned by the scraper roller 200 and the brush roller 300, thereby achieving the cleaning and discharge of leather burrs, particles, hair scraps, paper scraps and other waste materials to a greater extent.

[0047] The material receiving area A2 includes the aforementioned first waste receiving portion 500 and second waste receiving portion 600. The first waste receiving portion 500 is used to receive waste materials (such as burrs, particles, hair scraps, paper scraps, etc.) generated after the leather is cleaned by the scraper roller 200 and the brush roller 300. The second waste receiving portion 600 is used to receive waste materials (such as particles, hair scraps, paper scraps, etc.) generated after the leather is cleaned by the blowing mechanism 400.

[0048] In addition, continue to refer to Figures 1 to 3 , illustratively, the leather processing device of the embodiment of the present application further includes a plurality of pressure rollers 700 that serve as a conveying device.

[0049] Exemplarily, the pressing roller 700 includes a first pressing roller 701. It can be seen that the top of the leather processing device (eg Figure 2 The end indicated by the Z1 direction is provided with a plurality of first pressing rollers 701, which are used to make the leather pass through: two scraper rollers 200, a brush roller 300, and a blowing mechanism 400 in sequence, and be transported to an external device by the blowing mechanism 400.

[0050] That is to say, a part of the first pressing roller 701 can transport the leather that has been punched but not cleaned to the scraper roller 200, the brush roller 300, and the blowing mechanism 400 in sequence. Finally, the leather that has passed the blowing mechanism 400 can be transported by another part of the first pressing roller 701 to the next process (such as a winding device, not shown in the figure).

[0051] The embodiment of the present application does not elaborate on or specifically limit the number and position of the first pressing rollers 701 , and anything that can achieve the above functions falls within the protection scope of the embodiment of the present application.

[0052] When punching holes in leather, a cardboard is added under the leather as a support and buffer for the punching. After punching, the cardboard and the leather need to be separated. For example, the bottom end of the leather processing device (such as Figure 2 A plurality of second pressing rollers 702 are provided along the second direction (as indicated by the Z2 direction). Figure 2 In the Z direction shown in FIG), at least one third pressing roller 703 is provided in the middle of the leather processing device.

[0053] That is to say, when the leather enters the leather processing device of the embodiment of the present application, the PVC layer and base cloth of the leather are transported to the clean area A1 through the first pressing roller 701, while the cardboard is transported to the second pressing roller 702 through the third pressing roller 703, and then transported to the next process (such as the paper collection device, not shown in the figure) by the second pressing roller 702.

[0054] The embodiment of the present application does not elaborate on or specifically limit the number and position of the second pressing roller 702 and the third pressing roller 703. As long as the above functions can be achieved, they are within the protection scope of the embodiment of the present application.

[0055] Meanwhile, continue to refer to Figures 1 to 3 For example, the leather processing device of the embodiment of the present application further includes a motor 800, which is arranged on one side of the frame 100 (eg Figure 3 The motor 800 can drive the scraper roller 200, the brush roller 300, the first pressing roller 701, the second pressing roller 702, and the third pressing roller 703 to rotate.

[0056] The scraper roller 200 , the brush roller 300 and the purging mechanism 400 in the cleaning area A1 are described in detail below.

[0057] refer to Figure 3 and Figure 4 Each of the scraper rollers 200 moves in a first direction (eg Figure 3 The scraper roller 200 extends in the Y direction shown in the figure, and both ends of each scraper roller 200 are connected to the frame 100. For example, the two ends of the scraper roller 200 can be fixed to the frame 100 by key connection or the like, but the embodiment of the present application does not limit this connection method.

[0058] refer to Figure 5 Each scraper roller 200 includes a plurality of cutter heads 201. When the scraper roller 200 rotates, the plurality of cutter heads 201 can rotate relative to the surface of the leather and scrape to remove burrs on the leather base cloth, residual particles in the PVC layer, residual particles in the base cloth, etc.

[0059] refer to Figure 5 and Figure 6 Combined with Figure 3 In one possible embodiment, each scraper roller 200 further includes a scraper roller along the first direction (such as Figure 3 The roller core 202 extending in the Y direction shown in FIG. Figure 6 As shown, the roller core 202 is a hexahedron, and each of the six planes is provided with a cutter head 201 , that is, each cutter head 201 is respectively arranged to fit the roller core 202 in a direction parallel to each plane of the roller core 202 .

[0060] For example, the present embodiment does not limit the structure of the roller core 202; the roller core 202 may also be in a conical, tetrahedral, or pentahedral shape. Accordingly, the present embodiment does not limit the number of cutter heads 201; for example, the cutter heads 201 may be provided on only one plane of the roller core 202 or on any number of planes.

[0061] For example, Figure 6 As shown, the scraper roller 200 further includes a first bearing 203, which is disposed inside the roller core 202. The motor 800 (eg Figure 3 As shown) can drive the first bearing 203 to rotate.

[0062] For example, Figure 6 As shown, each cutter head 201 can be fixed to the corresponding plane of the roller core 202 by a bolt 204. The embodiment of the present application does not limit the connection method between the cutter head 201 and the roller core 202.

[0063] refer to Figure 3 and Figure 4 Each of the above brush rollers 300 moves along a first direction (eg Figure 3 The two ends of each brush roller 300 are connected to the frame 100. For example, the two ends of the brush roller 300 can be fixed to the frame 100 by key connection or the like, but the embodiment of the present application does not limit this connection method.

[0064] refer to Figure 7 and Figure 8 Combined with Figure 3Each brush roller 300 includes a plurality of brush filaments 301. When the brush roller 300 rotates, the plurality of brush filaments 301 can rotate relative to the surface of the leather and brush away burrs on the leather base fabric, residual particles on the PVC layer, residual particles on the base fabric, etc.

[0065] Illustratively, each brush roller 300 further includes a brush roller body 302 , the brush roller body 302 extends along a first direction, and a plurality of bristles 301 are disposed on an outer surface of the brush roller body 302 .

[0066] For example, each brush roller 300 further includes a second bearing 303, which is disposed inside the brush roller body 302. The motor 800 (eg Figure 3 As shown) can drive the second bearing 303 to rotate.

[0067] refer to Figure 3 and Figure 4 The purge mechanism 400 is provided on the frame 100 . The purge mechanism 400 is a device capable of generating airflow, which can blow away or remove the object to be cleaned on the surface of the object (eg, leather).

[0068] For example, the purge mechanism 400 is blown along a first direction (eg Figure 3 The purge mechanism 400 extends in the Y direction (shown in FIG), and both ends of the purge mechanism 400 are connected to the frame 100. For example, both ends of the purge mechanism 400 can also be fixed to the frame 100 by means of key connection or the like, but the embodiment of the present application does not limit this connection method.

[0069] refer to Figure 9 and combined Figure 3 The blowing mechanism 400 includes two air outlets 401, which can blow the surface of the leather. The embodiment of the present application does not specifically limit the number of air outlets 401. For example, one, three, seven, or other numbers of air outlets 401 can be provided.

[0070] In a possible embodiment, the blowing mechanism 400 includes an air knife 410, and the air outlet 401 is provided on the air knife 410. Figure 9 As shown, it can be seen that each air outlet 401 is along the length direction of the wind knife 410 (such as Figure 9 For example, the length direction of the wind knife 401 is parallel to the first direction (as shown in FIG. Figure 3 parallel to the Y direction shown in ).

[0071] In a possible embodiment, the wind knife 410 is further provided with four Figure 9 The air inlets 402 are arranged at intervals (direction B shown in FIG).

[0072] In another possible implementation, the purge mechanism 400 may further include an air gun (eg, an air blow gun, or another example, a pneumatic air blow gun), which is not limited in this embodiment of the present application.

[0073] refer to Figure 3 and Figure 4 Combined with Figure 9 In a possible embodiment, the leather processing device of the embodiment of the present application further includes: a fan 420 (such as a blower), and the fan 420 is connected to the four air inlets 402 of the wind knife 410 to supply a stronger airflow to the wind knife 410.

[0074] By adopting the above technical solution, a scraper roller 200, a brush roller 300 and a blowing mechanism 400 are sequentially arranged in the processing direction of the leather processing device, which can largely remove burrs, particles, hair scraps, paper scraps and other waste materials remaining after leather punching.

[0075] Specifically, the leather surface is first scraped using at least one scraper roller 200. For example, the scraper roller 200 is in close contact with the surface of the base fabric to scrape off burrs on the base fabric; for another example, during this process, some residual particles and paper scraps are also scraped off.

[0076] At least one brush roller 300 is then used to brush the leather surface. For example, the brush roller 300 is placed in close contact with the surface of the base fabric to remove lint from the burrs removed by the scraper roller 200. Alternatively, the brush roller 300 can further remove some residual particles and paper scraps. Finally, a strong airflow from the purge mechanism 400 is used to sweep the leather surface, completely removing any lint, particles, and paper scraps.

[0077] Therefore, in the leather processing device of the embodiment of the present application, the scraper roller 200, the brush roller 300 and the blowing mechanism 400 cooperate with each other to thoroughly remove the waste left on the surface of the leather after punching, avoiding the situation where the manual air gun blowing is incomplete and the air gun cannot remove burrs. The cleaning effect is better, and the problems of poor leather appearance and high scrap rate are completely solved. The degree of automation is high, and the leather processing efficiency is improved.

[0078] The first scrap receiving portion 500 and the second scrap receiving portion 600 in the material receiving area A2 are described in detail below.

[0079] refer to Figure 4 Combined with Figure 2 and Figure 3 The first waste receiving portion 500 is also correspondingly provided on the frame 100, along the second direction (such as Figure 4 The first waste receiving portion 500 is located at the bottom of the two scraper rollers 200 and the brush roller 300 (ie, located at the bottom of the scraper roller 200 and the brush roller 300). Figure 4The first scrap receiving portion 500 is disposed toward the two scraper rollers 200 and the brush roller 300. In other words, the first scrap receiving portion 500 can cover the two scraper rollers 200 and the brush roller 300 so as to receive scraps (e.g., burrs, particles, hair scraps, paper scraps, etc.) generated after the leather is cleaned by the scraper rollers 200 and the brush rollers 300.

[0080] In a possible embodiment, the first waste receiving portion 500 is arranged in a direction along the second direction and away from the scraper roller 200 and the brush roller 300 (eg Figure 5 The chip collecting device 500 includes a chip dumping plate assembly 510, a chip collecting bucket 520, a first chip collecting box 530 and a tray 540 in sequence.

[0081] Specifically, the chip removal plate assembly 510 includes a first plate body 511 and a second plate body 512. The first plate body 511 and the second plate body 512 are connected along the third direction (eg Figure 5 The first plate 511 and the second plate 512 are spaced apart relative to the second direction (as shown in the X direction). Figure 5 The Z direction shown in FIG is set at a certain inclination angle.

[0082] At the same time, a first receiving cavity 5100 is defined between the first plate 511 and the second plate 512. Figure 3 Y direction shown in FIG) and the third direction (as shown in FIG) Figure 5 The first receiving cavity 5100 covers the two scraper rollers 200 and the brush roller 300 .

[0083] Thus, the first plate 511 and the second plate 512 cooperate with each other to accommodate the waste materials generated by the scraper roller 200 and the brush roller 300 .

[0084] For example, the embodiment of the present application does not limit the inclination angle between the first plate 511 and the second plate 512. As long as it can accommodate the waste generated by the two scraper rollers 200 and the brush roller 300 during the cleaning process, it is within the protection scope of the embodiment of the present application.

[0085] Furthermore, one end of the scrap collecting bucket 520 (i.e. Figure 4 The end indicated by the Z1 direction in the middle) is connected to the first receiving cavity 5100 of the chip dumping plate assembly 510, and the other end of the chip collecting hopper 520 (ie Figure 4 The end (in the Z2 direction) has a second opening 521.

[0086] The first dust collecting box 530 defines a second receiving cavity 5300 , which is used to ultimately accommodate waste materials generated by the scraper roller 200 and the brush roller 300 . It can be seen that the second opening 521 of the dust collecting bucket 520 corresponds to the second receiving cavity 5300 .

[0087] The tray 540 is used to support the first dust collecting box 530. The tray 540 is arranged along the first direction (eg Figure 3 Both ends of the Y direction (shown in the figure) are fixed to the frame 100 respectively.
