Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, and in particular to a winding mechanism for a coating machine. Background Technology

[0002] Coating machines are mainly used for surface coating processes of films, paper, etc. This machine coats a roll of substrate with a layer of adhesive, paint or ink with a specific function, and after drying, cuts it into sheets or rolls it up. When rolling up the substrate, the take-up drum is placed on a rotating shaft, and the rotating shaft drives the take-up drum to rotate to achieve the winding of the substrate. Before winding, the operator needs to press one end of the substrate onto the take-up drum and wrap the substrate around the take-up drum several times before winding. This results in a large amount of manual labor and affects the winding efficiency of the substrate. After winding is completed, the next take-up drum needs to be replaced. Therefore, there is a problem of inconvenience in disassembling and assembling the take-up drum. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a winding mechanism for a coating machine to solve the problem of needing to press one end of the substrate onto the winding drum and wrap the substrate around the winding drum multiple times before winding.

[0004] To achieve the above objectives, this utility model provides a winding mechanism for a coating machine, including a base plate, with two mounting seats symmetrically distributed above the base plate, and further comprising: The take-up roller includes a take-up drum located between two mounting seats for taking up a substrate and baffles disposed at both ends of the take-up drum to limit the edge of the substrate. The winding unit includes a mounting shaft rotatably mounted on the mounting base and inserted inside the winding drum, a driver connected to one of the mounting shafts, and stop plates respectively fixedly mounted on the mounting shafts and inserted into the baffles for driving the winding drum to rotate. The clamping unit includes a pressure groove formed on the two stop plates and extending to both ends of the take-up drum, a pressure plate that slides on one side of the stop plates to clamp one end of the substrate inside the pressure groove, and an adjusting member for adjusting the height of the pressure plate.

[0005] Preferably, one end of one of the mounting shafts is provided with a plug, and one end of the other mounting shaft is provided with a slot adapted to the plug, wherein both the slot and the plug are rectangular structures.

[0006] Preferably, the driver includes a motor disposed on one side of the mounting base and connected to one end of one of the mounting shafts, and a base is mounted on the bottom end of the motor.

[0007] Preferably, the two stop plates are symmetrically provided with docking blocks on the side close to each other, and the two stop plates are provided with docking grooves adapted to the docking blocks on the side far apart from each other. Both the docking blocks and the docking grooves are rectangular structures.

[0008] Preferably, the base plate is provided with an adjustment unit for adjusting the distance between the two mounting seats. The adjustment unit includes a moving rod installed at the bottom end of the mounting seat and sliding on the top end of the base plate. The top end of the base plate is provided with a dual-axis motor. The output shaft of the dual-axis motor is connected to a lead screw threadedly connected to the moving rod.

[0017] This specification provides one or more embodiments of a coating machine's winding mechanism, such as... Figure 1 , Figure 2 and Figure 3 As shown, it includes a base plate 1, with two mounting bases 2 symmetrically distributed above the base plate 1, and also includes: The take-up roller includes a take-up drum 4 located between two mounting seats 2 for taking up the substrate and baffles 5 disposed at both ends of the take-up drum 4 to limit the edge of the substrate. The winding unit includes a mounting shaft 3 rotatably mounted on the mounting base 2 and inserted inside the winding drum 4, a driver connected to one of the mounting shafts 3, and stop plates 6 fixedly mounted on the mounting shafts 3 and inserted into the baffle 5 for driving the winding drum 4 to rotate. The clamping unit includes a pressure groove 8 formed on the two stop plates 6 and extending to both ends of the take-up drum 4, a pressure plate 11 that slides on one side of the stop plates 6 to clamp one end of the substrate inside the pressure groove 8, and an adjusting member for adjusting the height of the pressure plate 11.

[0018] In use, the operator holds one end of the substrate and places it on the take-up drum 4 between the pressure groove 8 and the pressure plate 11. Then, the height of the pressure plate 11 is adjusted by the adjusting device so that the pressure plate 11 can press one end of the substrate into the pressure groove 8. This achieves clamping of one end of the substrate by the pressure plate 11 and the side wall of the pressure groove 8 on the take-up drum 4, thereby fixing the substrate and providing stability for the take-up drum 4 to wind the substrate. This avoids the need for the operator to hold the substrate and fix it on the take-up drum 4 and then need to wind it multiple times before releasing the substrate. Then, the driver drives the mounting shaft 3 to rotate, which in turn drives the stop plate 6 to rotate the take-up drum 4, thereby achieving the winding of the substrate by the take-up drum 4.

[0019] In embodiments of this utility model, such as Figure 3 and Figure 4 As shown, one end of one of the mounting shafts 3 is provided with a plug 17, and one end of the other mounting shaft 3 is provided with a slot 16 adapted to the plug 17. Both the slot 16 and the plug 17 are rectangular structures. This design facilitates the docking of the two mounting shafts 3 through the insertion of the slot 16 and the plug 17. Furthermore, the rectangular structure of the slot 16 and the plug 17 makes it possible for one mounting shaft 3 to synchronously drive the other mounting shaft 3 to rotate.

[0020] In embodiments of this utility model, such as Figure 1 , Figure 3 and Figure 4 As shown, the driver includes a motor 7 disposed on one side of the mounting base 2 and connected to one end of one of the mounting shafts 3. A base is mounted on the bottom end of the motor 7. This design allows the motor 7 to rotate when it is started, causing one of the mounting shafts 3 to rotate. The slot 16 and the insert rod 17 then cause the other mounting shaft 3 to rotate synchronously, facilitating the rotation of the two stop plates 6. Through the insertion of the docking block 14 and the docking groove 15, the synchronous rotation of the winding drum 4 can be achieved, enabling the winding drum 4 to wind the substrate.

[0021] In embodiments of this utility model, such as Figure 3 and Figure 4 As shown, each of the two stop plates 6 has a symmetrically arranged docking block 14 on its adjacent side, and each of the two baffles 5 has a docking groove 15 adapted to the docking block 14 on its opposite side. Both the docking block 14 and the docking groove 15 are rectangular structures. This design allows the baffles 5 and the stop plates 6 to be connected by inserting the docking block 14 and the docking groove 15, facilitating the winding of the substrate by the winding drum 4.

[0022] In embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the base plate 1 is provided with an adjustment unit for adjusting the distance between the two mounting seats 2. The adjustment unit includes a moving rod 18 installed at the bottom end of the mounting seat 2 and sliding on the top end of the base plate 1. The top end of the base plate 1 is provided with a dual-axis motor 19. The output shaft of the dual-axis motor 19 is connected to a lead screw 20 that is threadedly connected to the moving rod 18. The base plate 1 is provided with a base 21 that is rotatably connected to one end of the lead screw 20. It should be noted that the threads of the two lead screws 20 are turned in opposite directions. With this design, when the take-up drum 4 has finished winding the substrate and it is necessary to replace it with the next take-up drum 4, the dual-axis motor 19 is started. The dual-axis motor 19 drives the lead screw 20 to rotate. Through the threaded connection between the lead screw 20 and the moving rod 18 and the sliding action between the moving rod 18 and the base plate 1, the moving rod 18 will drive the mounting seat 2 to move, so that the two mounting seats 2 are far apart. The mounting seat 2 will drive the mounting shaft 3 to move, so that the two mounting shafts 3 are disconnected. This makes it easy to pull the mounting shaft 3 out of the take-up drum 4, disconnect the support for the take-up drum 4, and effectively facilitate the replacement of the take-up drum 4.

[0023] In embodiments of this utility model, such as Figure 2 , Figure 3 and Figure 4 As shown, the adjusting component includes a fixing plate 9 fixed to the side wall of the stop plate 6. A threaded rod 10 is rotatably mounted on the fixing plate 9, passing through the pressure plate 11. The threaded rod 10 is threadedly connected to the pressure plate 11. With this design, when the mounting shaft 3 is inserted into the take-up drum 4 and the mating groove 15 on the baffle 5 is aligned with the mating block 14 on the stop plate 6, the movement of the mounting shaft 3 will cause the stop plate 6 to move closer to the baffle 5, so that the mating block 14 is inserted into the mating groove 15. Simultaneously, the pressure plate 11 will be positioned in the pressure groove 8. Then, the operator pulls one end of the substrate onto the take-up drum 4, placing it between the pressure groove 8 and the pressure plate 11. Then, the threaded rod 10 is rotated, and the threaded connection between the threaded rod 10 and the pressure plate 11 is closed. The sliding action of the pressure plate 11 and the side wall of the stop plate 6 causes the threaded rod 10 to rotate, causing the pressure plate 11 to move downward. The pressure plate 11 presses down on one end of the substrate, pressing the substrate into the pressure groove 8. This effectively clamps the substrate at one end of the substrate using the pressure plate 11 and the side wall of the pressure groove 8. This design avoids the need for manual handling of the substrate on the winding drum 4 and the need to wrap it several times before releasing it. It effectively facilitates the winding of the substrate by the winding drum 4 and speeds up the winding efficiency of the substrate.

[0024] In embodiments of this utility model, such as Figure 3As shown, a slider 13 is provided on one side of the pressure plate 11, and a sliding opening 12 is provided on the stop plate 6 for the slider 13 to slide in contact with the stop plate 6. This design, by allowing the slider 13 to slide within the sliding opening 12, effectively facilitates the stable movement of the pressure plate 11.
