Description

Technical Field

[0001] This application relates to the field of coating machines, and more particularly to a sheet material transport device for a coating machine. Background Technology

[0002] A coating machine is an industrial device that uses automated or semi-automated methods to uniformly, quantitatively, and accurately apply specific types of liquid, colloidal, or thin film materials to the surface of a workpiece.

[0003] Metal sheets are typically coated using a coating machine. The general workflow involves pre-treating the sheet (cleaning and degreasing, surface conversion), washing and drying it, then applying the coating, followed by leveling, curing, and cooling before proceeding to the next step.

[0004] Metal sheets are typically transported using multiple rollers driving multiple conveyor belts. During transport, lateral displacement and swaying can occur, which can easily lead to scratches and other problems, thus affecting the coating quality of the metal sheets. Utility Model Content

[0005] To address the problem of scratches caused by shaking during the transportation of thin metal sheets, which affects the coating quality, this application provides a sheet transportation device for a coating machine.

[0006] The sheet material transport device for a coating machine provided in this application adopts the following technical solution: A sheet metal transport device for a coating machine includes a frame, on which a transport assembly is mounted. The transport assembly includes pulleys and a transport belt. Multiple pulleys are rotatably mounted on the frame and arranged in parallel. The transport belt is sleeved on two adjacent pulleys. A limiting assembly is mounted on the frame, including a limiting frame and a clamping member. The limiting frame is located on the frame at opposite sides in the sheet metal transport direction. The clamping member is located on the limiting frame and above the transport belt. The clamping member is used to clamp one side of the sheet metal. The limiting frame is provided with an edge-stopping mechanism for limiting the side edge of the sheet metal.

[0007] By adopting the above technical solution, the metal sheet is conveyed on the conveyor belt, the limiting frame is set on the opposite sides of the conveying direction, the clamping component presses the sheet on one side from the top of the conveyor belt to limit the vertical jump of the sheet, and at the same time, the edge blocking mechanism limits the side of the sheet to prevent the sheet from lateral displacement during the transportation process, reducing the probability of the sheet scratching other parts of the equipment and improving the coating quality.

[0008] Optionally, the clamping component includes a clamping plate and a guide rod. The guide rod is slidably mounted on the limiting frame in a vertical direction. The clamping plate is disposed at one end of the limiting frame. The clamping plate and the conveyor belt are distributed parallel to each other and along the conveying direction of the plate. The limiting frame is provided with an adjusting component for adjusting the position of the clamping plate.

[0009] By adopting the above technical solution, during transportation, the adjusting component adjusts the position of the pressing plate, the guide rod provides guidance for the vertical movement of the pressing plate, and the height of the pressing plate is adjusted according to the metal sheet of different thicknesses, so that the pressing plate can be adapted to various specifications of sheet metal.

[0010] Optionally, the adjusting component includes an adjusting screw and an adjusting plate. The adjusting screw is threaded onto the limiting frame, and the adjusting plate is disposed at one end of the adjusting screw and slidably connected to the limiting frame. The adjusting plate is connected to the pressing plate.

[0011] By adopting the above technical solution, rotating the adjusting screw drives the adjusting plate to slide along the limiting frame, controlling the moving distance of the adjusting plate, and thus adjusting the distance between the pressing plate and the conveyor belt, making the adjustment operation convenient.

[0012] Optionally, the adjusting plate is provided with an elastic element, and the adjusting plate is connected to the pressing plate through the elastic element.

[0013] By adopting the above technical solution, the setting of the elastic element enables an elastic connection between the pressure plate and the adjustment plate. When there are small protrusions on the surface of the plate or slight vibrations occur during transportation, the elastic element absorbs the impact force through its own deformation, reducing the rigid compression of the plate by the pressure plate, thereby reducing the damage to the surface of the plate caused by compression.

[0014] Optionally, the elastic element includes a first spring and an adjusting rod. The adjusting rod is slidably mounted on the adjusting plate. The adjusting rod and the adjusting screw are distributed parallel to each other. One end of the adjusting rod is connected to the pressure plate. The first spring is sleeved on the adjusting rod. One end of the first spring is connected to the pressure plate. The end of the first spring away from the pressure plate is connected to the adjusting plate.

[0015] By adopting the above technical solution, when the pressing plate is pushed, the adjusting rod slides along the adjusting plate. At this time, the first spring is deformed and compressed. The adjusting rod provides guidance for the deformation of the first spring, ensuring the stability of the pressing force. The elastic pressing reduces the probability of damaging the plate and improves the stability and reliability of the pressing plate pressing the plate.

[0016] Optionally, the edge-blocking mechanism includes an edge-blocking plate and a pushing member. The edge-blocking plate is vertically arranged on the limiting frame and distributed along the transport direction of the plate. The pushing member is arranged on the limiting frame and is used to push the edge-blocking plate against the side of the plate.

[0017] By adopting the above technical solution, the side guard plate is set vertically and distributed along the transport direction of the plate, forming a long-term and large-area contact limit with the side of the plate. The pushing component continuously applies a pushing force to the side guard plate, so that the side guard plate is always pressed against the side of the plate, blocking the lateral displacement of the plate and reducing the scratching problem caused by the lateral displacement of the plate.

[0018] Optionally, the pushing component includes a second spring and a pushing block. The limiting frame is provided with a pushing groove, and the limiting frame is provided with a pushing rod located at the pushing groove. The pushing block is slidably connected to the pushing rod, and the second spring is sleeved on the pushing rod and connected to one side of the pushing block.

[0019] By adopting the above technical solution, the push block and the push rod are slidably connected, and the second spring elastically presses against the side plate to ensure the pressing effect on the side of the plate. When there is a slight collision between the side of the plate and the side plate or a slight fluctuation in the width of the plate, the second spring absorbs the impact force through its own deformation, reducing the rigid impact of the side plate on the side of the plate and reducing the damage to the side of the plate.

[0020] Optionally, the limiting frame is slidably mounted on the frame in a direction toward or away from the conveyor belt, and a limiting screw is rotatably mounted on the frame. The limiting screw is distributed perpendicular to the conveying direction of the sheet metal, and the limiting frame is threadedly connected to the limiting screw.

[0021] By adopting the above technical solution, the limiting screw is rotated to drive the limiting frame to slide laterally along the frame, thereby adjusting the distance between the two limiting frames. The limiting range is adjusted according to the actual width of the plate to be transported, ensuring that the edge blocking mechanism and the clamping parts can effectively limit and clamp plates of different widths, thus improving the device's limiting adaptability.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The limiting frame and clamping parts restrict the vertical movement of the sheet material, and the edge blocking mechanism limits the side of the sheet material, preventing lateral displacement of the sheet material during transportation, reducing the probability of the sheet material scratching other parts of the equipment, and improving the coating quality. 2. The adjusting component can adjust the height of the clamping plate according to the different thicknesses of metal sheets, so that the clamping plate can be adapted to various specifications of sheet metal; 3. Rotating the limit screw can adjust the distance between the limit frames on both sides, and adjust the limit range according to the actual width of the plate to be transported, so as to ensure that the edge guard mechanism and the clamping parts can effectively limit and clamp the plates of different widths, and improve the limit adaptability of the device.

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] This application discloses a sheet metal transport device for a coating machine, referring to... Figure 1 and Figure 2The system includes a frame 1, a transport assembly 2, and a limiting assembly. The transport assembly 2 is mounted on the frame 1 and includes pulleys 21 and a transport belt 22. Multiple pulleys 21 are rotatably mounted on the frame 1 and arranged in parallel. The transport belt 22 is fitted onto adjacent pulleys 21. The multiple transport belts 22 are distributed in parallel to form a transport plane. When the pulleys 21 rotate, the transport belt 22 moves accordingly, thereby transporting the sheet material. The limiting assembly is also mounted on the frame 1 and includes a limiting frame 3 and a clamping component 4. The limiting frame 3 is mounted on the frame 1 and located on opposite sides in the sheet material transport direction. The clamping component 4 is mounted on the limiting frame 3 and located above the transport belt 22, used to clamp one side of the sheet material, limiting its vertical movement. The limiting frame 3 also has an edge-blocking mechanism 5, which limits the side of the sheet material, preventing lateral displacement during transport. This limiting and clamping mechanism reduces scratches and improves coating quality.

[0030] Reference Figure 1 and Figure 2 The frame 1 is equipped with a support and a guide rod 42. The limiting frame 3 is slidably installed on the support and slidably connected to the guide rod 42. A limiting screw 11 is rotatably installed on the frame 1 in a direction perpendicular to the material transport direction. The limiting frame 3 is threadedly connected to the limiting screw 11. By rotating the limiting screw 11, the limiting frame 3 is driven to slide laterally along the frame 1, thereby adjusting the distance between the two limiting frames 3. The limiting range is adjusted according to the actual width of the material to be transported, ensuring that the edge retaining mechanism 5 and the clamping component 4 can effectively limit and clamp materials of different widths, improving the device's limiting adaptability.

[0031] Reference Figure 1 and Figure 2 The clamping component 4 includes a clamping plate 41 and a guide rod 42. The guide rod 42 is slidably mounted on the limiting frame 3 in a vertical direction. The clamping plate 41 is horizontally positioned at one end of the guide rod 42 and distributed along the conveying direction of the sheet metal. The limiting frame 3 is equipped with an adjusting component 6, which includes an adjusting screw 61 and an adjusting plate 62. The adjusting screw 61 is vertically threaded onto the limiting frame 3. The adjusting plate 62 is horizontally positioned at the downward-facing end of the adjusting screw 61 and is slidably connected to the limiting frame 3 in a vertical direction via a connecting rod. The adjusting plate 62 is connected to the clamping plate 41. When the adjusting screw 61 is rotated, it causes the adjusting plate 62 to slide along the limiting frame 3, thereby controlling the movement distance of the adjusting plate 62 and adjusting the distance between the clamping plate 41 and the conveyor belt 22 to accommodate sheet metal of different thicknesses.

[0032] Reference Figure 1 and Figure 2An elastic element 7 is provided on the adjusting plate 62. The elastic element 7 includes a first spring 71 and an adjusting rod 72. The adjusting rod 72 is vertically slidably mounted on the adjusting plate 62. One downward end of the adjusting rod 72 is connected to the pressure plate 41. The first spring 71 is sleeved on the adjusting rod 72. One downward end of the first spring 71 is connected to the pressure plate 41, and the other end is connected to the adjusting plate 62. When the pressure plate 41 is pushed, the adjusting rod 72 will slide along the adjusting plate 62. At this time, the first spring 71 will deform and compress. The adjusting rod 72 provides guidance for the deformation of the first spring 71, ensuring the stability of the clamping force. At the same time, the elastic clamping can reduce the probability of damaging the plate and improve the stability and reliability of the pressure plate 41 in clamping the plate.

[0033] Reference Figure 2 and Figure 3 The edge-blocking mechanism 5 includes an edge-blocking plate 51 and a pushing component 52. The edge-blocking plate 51 is distributed along the transport direction of the sheet material, forming a long-term, large-area contact limit with the side of the sheet material. The pushing component 52 includes a second spring 521 and a pushing block 522. A pushing groove 31 is provided on the limiting frame 3, and a pushing rod 32 is provided at the pushing groove 31 on the limiting frame 3. The pushing block 522 is slidably connected to the pushing rod 32. The second spring 521 is sleeved on the pushing rod 32 and connected to one side of the pushing block 522. The sliding connection between the pushing block 522 and the pushing rod 32 ensures that the edge-blocking plate 51 can move flexibly, and the second spring 521 elastically presses against the edge-blocking plate 51 to ensure a pressing effect on the side of the sheet material. When there is a slight collision between the side of the sheet material and the edge-blocking plate 51 or a slight fluctuation in the width of the sheet material, the second spring 521 absorbs the impact force through its own deformation, reducing the rigid impact of the edge-blocking plate 51 on the side of the sheet material and reducing damage to the side of the sheet material.

[0034] The implementation principle of the sheet material transportation device of the coating machine in this application embodiment is as follows: the sheet material is placed on the conveyor belt 22, the pulley 21 rotates, driving the conveyor belt 22 to move, thereby realizing the transportation of the sheet material.

[0035] Based on the actual width of the sheet material to be transported, the limiting screw 11 on the rotating frame 1 is rotated, causing the limiting frame 3 to slide laterally along the frame 1, thereby adjusting the distance between the two limiting frames 3 so that the edge-blocking mechanism 5 and the clamping member 4 can be in the appropriate position; based on the thickness of the sheet material, the position of the clamping plate 41 is adjusted. The adjusting screw 61 on the limiting frame 3 is rotated, causing the adjusting plate 62 to slide along the limiting frame 3, controlling the moving distance of the clamping plate 41, thereby adjusting the distance between the clamping plate 41 and the conveyor belt 22 so that the clamping plate 41 can adapt to sheets of different thicknesses.

[0036] During the transportation of the sheet material, the clamping plate 41 presses down on one side of the sheet material. When there are small protrusions on the surface of the sheet material or slight vibrations occur during transportation, the clamping plate 41 is pushed, the adjusting rod 72 slides along the adjusting plate 62, and the first spring 71 is deformed and compressed to ensure the stability of the clamping force.

[0037] The second spring 521 elastically presses against the push block 522, thereby ensuring that the edge plate 51 is always pressed against the side of the plate. When there is a slight collision between the side of the plate and the edge plate 51 or a slight fluctuation in the width of the plate, the second spring 521 absorbs the impact force through its own deformation, reducing the rigid impact of the edge plate 51 on the side of the plate.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
