Description

Technical Field

[0001] This utility model relates to the field of leather production technology, specifically to a uniform spraying device for sheepskin production. Background Technology

[0002] Leather is animal hide that has undergone physical and chemical processing, such as hair removal and tanning, to become deformed and less prone to decay. Animal leather, such as sheepskin, is often used to make shoes, clothing, and other leather goods.

[0003] During the production process, sheepskin needs to be coated with a coating agent using a spraying device to protect the leather, increase its luster, and improve its wear resistance. Similarly, before spraying, the dust on the surface of the sheepskin needs to be cleaned to ensure stronger adhesion of the coating.

[0004] Although some existing spraying devices have a mechanism for cleaning sheepskin, during the sheepskin transport process, the moving sheepskin comes into contact with the stationary brush, and the static electricity generated by friction is used to attract and clean the dust on the surface of the sheepskin. However, after a long period of use, dust and other impurities gradually stick to and even accumulate on the brush, so the brush needs to be disassembled and cleaned regularly.

[0005] However, existing brush disassembly and assembly technologies often require shutting down the entire spraying and conveying equipment before disassembling and replacing the brushes, resulting in long downtime and reduced processing efficiency of the sheepskin. Utility Model Content

[0006] In view of this, the present invention provides a uniform spraying device for sheepskin production. By providing a quick-change cleaning mechanism, the overall downtime of the equipment can be reduced when changing brushes, thereby effectively ensuring the processing efficiency of sheepskin and solving the problem of long downtime and reduced production efficiency caused by brush replacement.

[0007] To solve the above-mentioned technical problems, this utility model provides a uniform spraying device for sheepskin production, including a workbench and a conveying mechanism inside the workbench. A frame is provided on one side of the upper part of the workbench, and a shell is provided on one side wall of the frame. A rotating rod is rotatably mounted on the inner side wall of the shell, and a rotating block is rotatably mounted on the outer side wall of the shell. The end of the rotating block is connected to one end of the rotating rod. A cleaning mechanism is provided on the surface of the rotating rod. The cleaning mechanism includes three brushes evenly distributed along the circumferential surface of the rotating rod. When the sheepskin is transported by the conveying mechanism, the bottom brush can contact the surface of the sheepskin for cleaning. When the bottom brush needs to be replaced due to dust accumulation, simply rotate the rotating block to switch to the spare brush to continue cleaning, reducing the overall downtime of the equipment and thus effectively ensuring the processing efficiency of the sheepskin.

[0008] The cleaning mechanism also includes three fixed columns evenly distributed on the circumferential surface of the rotating rod. The ends of the fixed columns are equipped with mounting frames, and the brush plate is set inside the mounting frames. The U-shaped mounting frames provide stable support for the brush plate. The rigid connection between the fixed columns and the mounting frames ensures the stability of the brush plate.

[0009] A positioning component is provided on the outer wall of the housing. The positioning component is used to position and fix the position of the rotating rod. It adopts the mechanical locking principle and locks the rotating rod through the positioning component to prevent the rotating rod from rotating accidentally during the operation of the equipment.

[0010] The positioning assembly includes a fixing block fixed to the outer wall of the housing, positioned directly above the rotating block. A through hole is formed in the center of the fixing block, through which a matching positioning rod passes. Three positioning holes are evenly distributed circumferentially on the surface of the rotating block. The positioning rod passes through the through hole of the fixing block and is inserted into one of the positioning holes. When the positioning rod is inserted into one of the positioning holes, one of the brush plates can be positioned directly below the rotating rod. Pressing the positioning rod allows it to be inserted into the positioning hole. The fixing block limits and fixes the rotating block, thereby locking the rotating rod and the brush plate, ensuring that the rotating rod cannot rotate freely, thus guaranteeing that the brush plate is accurately positioned in the lower working position.

[0011] A connecting block is provided at the upper end of the positioning rod, and a tension spring is sleeved on the surface of the positioning rod. The upper end of the tension spring is fixed to the lower surface of the connecting block, and the lower end of the tension spring is fixed to the upper surface of the fixing block. When the brush plate needs to be replaced, the positioning rod is manually pulled to disengage it from the positioning hole. After rotating the rotating block to the next brush plate position, the positioning rod is released to insert it into the new positioning hole, thus locking the rotating rod.

[0012] The brush plate is detachably mounted on the mounting frame, which facilitates quick replacement of the old brush plate. When the new brush plate is used for cleaning, the old brush plate can be disassembled and cleaned by the staff, so that the cleaning of sheepskin will not be hindered when replacing the brush plate.

[0013] The brush plate has insertion holes, into which a matching rod is inserted. The rod has a limiting groove on its surface, and the inner wall of the insertion hole has a limiting strip. When the rod is inserted into the insertion hole, the limiting strip engages with the limiting groove of the rod. When the rod is inserted into the brush plate insertion hole, the limiting strip engages with the limiting groove to prevent the rod from rotating. Screws are provided at both ends of the rod. Through holes are provided on both sides of the mounting bracket. The screws pass through the through holes in the side walls of the mounting bracket and are locked in place by nuts. When installing the brush plate, align the insertion hole of the brush plate with the through hole in the side wall of the mounting bracket. Then, first pass the rod through the through hole on one side of the mounting bracket and insert it into the insertion hole. Finally, pass it through the through hole on the other side of the mounting bracket and tighten the nut to install it on the screw, thus fixing the brush plate in place. When the brush plate needs to be removed, loosen the nut to remove it, and then pull the rod out of the insertion hole.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. When using this utility model, if the brush plate below needs to be replaced due to dust accumulation, simply rotate the rotating block to switch to the spare brush plate to continue cleaning, reducing the overall downtime of the equipment and thus effectively ensuring the processing efficiency of sheepskin.

[0015] 2. When using this utility model, pressing the positioning rod will insert it into the positioning hole. The positioning rod will limit and fix the rotating block through the limiting of the fixing block, thereby locking the rotating rod and the brush plate, ensuring that the rotating rod cannot rotate freely, and thus ensuring that the brush plate is accurately located in the lower working position.

[0016] 3. When using this utility model, the old brush plate can be disassembled and cleaned by the staff when the new brush plate is used for cleaning, so that the cleaning work of sheepskin will not be hindered when replacing the brush plate.

[0017] 4. When using this utility model, when installing the brush plate, align the insertion hole of the brush plate with the through hole on the side wall of the mounting bracket. Then, first pass the insertion rod through the through hole on one side of the mounting bracket and insert it into the insertion hole. Finally, pass it through the through hole on the other side of the mounting bracket and install it on the screw by tightening the nut, thereby fixing the brush plate in place. When it is necessary to disassemble the brush plate, loosen the nut to remove it, and then pull the insertion rod out of the insertion hole. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0021] A uniform spraying device for sheepskin production, such as Figure 1-4 The workbench 100 includes a worktable 100 and a conveying mechanism within it. A frame 200 is mounted on one side of the upper part of the worktable 100, and a spraying machine is installed inside the frame 200. The conveying mechanism and the spraying machine are common devices in the prior art for conveying and spraying sheepskins. The conveying mechanism transports the sheepskins to the frame 200, and the spraying machine sprays liquid onto the sheepskins being conveyed. A housing 300 is mounted on one side wall of the frame 200. A rotating rod 400 is rotatably mounted on the inner wall of the housing 300 via bearings. Two coaxial bearings are installed on the inner wall of the housing 300, fixing both ends of the rotating rod 400 to the inner wall of the bearings, thereby allowing the rotating rod to rotate. The rotating rod 400 is rotatable. A rotating block 604 is rotatably mounted on the outer side wall of the housing 300. The end of the rotating block 604 passes through the side wall of the housing 300 and is connected to one end of the rotating rod 400. A cleaning mechanism is provided on the surface of the rotating rod 400. The cleaning mechanism includes three brush plates 500 that are detachably mounted on the rotating rod 400. The three brush plates 500 are evenly distributed in a ring along the circumferential surface of the rotating rod 400, and the spacing between each pair of brush plates 500 is the same. When the workers place the sheepskin on the conveyor mechanism for transportation, the sheepskin will first pass through the bottom brush plate 500. The brush at the bottom of the brush plate 500 will contact the sheepskin to clean the debris on the surface of the sheepskin. When brush plate 500 needs to be replaced, rotate the rotating block 604, causing the rotating block 604 to drive the rotating rod 400 to rotate. The rotating rod 400 drives the fixed column 401 and the mounting frame 402 to rotate synchronously. The mounting frame 402 drives the brush plates 500 to move synchronously, so that the three brush plates 500 rotate synchronously along the axial direction of the rotating rod 400. This allows the brush plate 500 that needs to be replaced to rotate to the top, while the other adjacent brush plate 500 moves to the bottom of the rotating rod 400, allowing the other brush plate 500 to continue cleaning the sheepskin. When changing brushes, rotating the rotating block 604 can switch to the spare brush plate 500 to continue cleaning, thereby reducing a lot of downtime and effectively ensuring the processing efficiency of sheepskin. This solves the problem of long downtime and reduced production efficiency caused by brush replacement.

[0022] Specifically, the cleaning mechanism also includes three fixed posts 401, which are evenly distributed circumferentially on the surface of the rotating rod 400. Each fixed post 401 has a mounting bracket 402 at its end. The mounting bracket 402 has a U-shaped structure, and the brush plate 500 is set on both sides of the U-shaped structure of the mounting bracket 402. The fixed posts 401 fix the brush plate 500 to the rotating rod 400. When the rotating rod 400 rotates, the fixed posts 401 synchronously drive the brush plate 500 to rotate. The U-shaped mounting bracket 402 provides stable support for the brush plate 500. The rigid connection between the fixed posts 401 and the mounting bracket 402 ensures that the brush plate 500 remains stable during high-speed rotation, avoiding the impact of shaking on cleaning accuracy.

[0023] according to Figure 4 As shown, a positioning component is provided on the outer wall of the housing 300. The positioning component is used to position and fix the position of the rotating rod 400. It adopts the mechanical locking principle and locks the rotating rod 400 through the positioning component to prevent the rotating rod 400 from rotating accidentally during the operation of the equipment.

[0024] Specifically, the positioning component includes a fixing block 600 fixed to the outer wall of the housing 300, and the fixing block 600 is located directly above the rotating block 604. The fixing block 600 has a through hole in its center, and a matching positioning rod 601 passes through the through hole. The rotating block 604 has three positioning holes evenly distributed around its surface. The positioning rod 601 passes through the through hole of the fixing block 600 and is inserted into the positioning hole. When one of the brush plates 500 can rotate to the position directly below the rotating rod 400, and when one of the positioning holes on the surface of the rotating block 604 can accurately correspond to the position directly below the positioning rod 601, the operator can press the positioning rod 601 to insert it into the positioning hole. Through the limiting of the fixing block 600, the positioning rod 601 limits and fixes the rotating block 604, thereby locking the rotating rod 400 and the brush plate 500, ensuring that the rotating rod 400 cannot rotate freely, thus ensuring that the brush plate 500 is accurately located in the lower working position.

[0025] Furthermore, a connecting block 603 is provided at the upper end of the positioning rod 601, and a tension spring 602 is sleeved on the surface of the positioning rod 601. The upper end of the tension spring 602 is fixed to the lower surface of the connecting block 603, and the lower end of the tension spring 602 is fixed to the upper surface of the fixing block 600. When the brush plate 500 needs to be replaced, the positioning rod 601 is manually pulled to disengage it from the positioning hole. After rotating the rotating block 604 to the position of the next brush plate 500, the positioning rod 601 is released to insert into the new positioning hole, thus completing the locking of the rotating rod 400.

[0026] according to Figure 4 and Figure 5As shown, the brush plate 500 is detachably mounted on the mounting bracket 402, which facilitates quick replacement of the old brush plate 500. When the new brush plate 500 is used for cleaning, the staff can disassemble and clean the old brush plate 500, so that the cleaning work of the sheepskin will not be hindered when replacing the brush plate 500.

[0027] Specifically, the brush plate 500 has an insertion hole 501, into which a matching insertion rod 700 is inserted. A limiting groove 701 is formed on the surface of the insertion rod 700, and a limiting strip 502 is provided on the inner wall of the insertion hole 501. When the insertion rod 700 is inserted into the insertion hole 501, the limiting strip 502 can engage with the limiting groove 701 of the insertion rod 700. When the insertion rod 700 is inserted into the insertion hole 501 of the brush plate 500, the limiting strip 502 engages with the limiting groove 701, preventing the insertion rod 700 from rotating. Screws 702 are provided at both ends of the insertion rod 700. Through holes are formed on both side walls of the mounting bracket 402. After the rod 702 passes through the through hole in the side wall of the mounting bracket 402, it is locked and fixed by the nut 703. When installing the brush plate 500, align the insertion hole 501 of the brush plate 500 with the through hole in the side wall of the mounting bracket 402. Then, first pass the rod 700 through the through hole on one side of the mounting bracket 402 and insert it into the insertion hole 501. Finally, pass it through the through hole on the other side of the mounting bracket 402. Finally, install it on the screw rod 702 by tightening the nut 703, thereby fixing the brush plate 500. When it is necessary to remove the brush plate 500, loosen the nut 703 to take it out, and then pull the rod 700 out of the insertion hole 501.

[0028] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
