Description

Technical Field

[0001] This utility model relates to the technical field of equipment for changing material coils, specifically an intelligent EVA head finding device. Background Technology

[0002] The head of a new roll needs to be welded to the tail of the next process for easy connection and feeding. In the previous material changeover process, the head of the material was manually located and then manually spliced, requiring the production line to stop and wait for the process to complete. Furthermore, due to varying operator skill levels, defects could easily occur, reducing production line efficiency. Therefore, this organization aims to improve these shortcomings.

[0003] Document CN201920857232 discloses a coating machine unwinding mechanism for easy material roll replacement, including a horizontal plate. A support leg is fixedly connected to the left side of the bottom of the horizontal plate, and a moving mechanism is fixedly connected to the right side of the bottom of the horizontal plate. A sliding groove is formed on the right side of the top of the horizontal plate, and a slider is slidably connected inside the sliding groove. This utility model utilizes the cooperative use of a horizontal plate, support leg, moving mechanism, housing, first bearing, screw, turntable, screw sleeve, moving rod, sliding groove, slider, active mechanism, moving plate, support base, motor, first frustum, material roll, driven mechanism, support plate, second bearing, rotating shaft, and second frustum. This structure still requires manual material replacement, which is cumbersome, time-consuming, labor-intensive, and has low work efficiency.

[0004] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the aforementioned issues, this utility model discloses an intelligent EVA feed head finding device, which optimizes the feeding and changing process, shortens the process time, increases overall production capacity, and facilitates personnel arrangement and allocation.

[0006] The technical solution of this utility model is as follows: an intelligent EVA feed head finding device, including a displacement device, a clamping device and a detection structure. The clamping device is located below the feed roll, and the displacement device is located above the feed roll. The clamping device includes a fixed plate, a moving plate, a receiving plate and a guide plate. The receiving plate is located inside the fixed plate, and the moving plate is located on one side of the fixed plate. The displacement device includes a guide rail and a base plate connected to the clamping device. A driving structure is provided on the base plate, and the detection structure is located inside the feed roll.

[0007] By adopting the above technical solution, when the material roll is unloaded, the displacement device adjusts the clamping device, and then the moving plate leaves the fixed plate, and the material head is located inside the guide plate. Then the material is unloaded until it enters between the moving plate and the fixed plate. After the detection structure detects it, the moving plate closes towards the fixed plate to press the material head, and then the rotary cylinder rotates 90° away from the material roll, so that the material head enters the next process.

[0008] Preferably, the clamping device is located between the clamping plates and below the drive unit connecting the material roll and the clamping plate. The material roll is fed upward toward the clamping device. The fixed plate has inverted L-shaped support plates at both ends. The inner side of the support plate is connected to the rotating rod through a rotary cylinder. The rotating rod is fixed with a fixed plate. The fixed plate is equipped with cylinder a. The output end of cylinder a passes through the fixed plate and is connected to the moving plate.

[0009] By adopting the above technical solution, the fixed plate can be rotated as a whole to adapt to the next process by means of a rotating cylinder and a rotating rod. The moving plate 4 extends by the drive of cylinder a5. When the material head passes through, cylinder a retracts and the moving plate clamps the material head.

[0010] Preferably, the bottom of the fixed plate is provided with an upward groove that does not penetrate the top of the fixed plate. The receiving plate is shaped like an upward convex character and fits perfectly into the groove. The two sides of the receiving plate are located inside the fixed plate. The receiving plate and the fixed plate are on the same plane. The moving plate is in close contact with the fixed plate and is driven by cylinder a on the fixed plate to extend outward.

[0011] By adopting the above technical solution, when the device rotates as a whole, the receiving plate can make the material head spread flat on the receiving plate, so that it can be welded to the next step and the material position, and the material head will not be facing downward.

[0012] Preferably, the inner surface of the moving plate is provided with an inward rectangular groove, the guide plate is located in the rectangular groove, the rectangular groove does not penetrate the bottom and outer side of the moving plate, the guide plate is located in the rectangular groove and is in the same plane as the moving plate, the part of the guide plate located outside the moving plate is inclined outward, and when the material roll is unloaded, the material roll is located exactly inside the guide plate.

[0013] By adopting the above technical solution, when the material head is feeding, the guide plate can guide the material head, so that the material head is fed between the moving plate and the fixed plate under the action of the guide plate. The guide plate can prevent the material head from being fed outward and accurately enter the position between the moving plate and the fixed plate.

[0014] Preferably, cylinders b are provided on both sides of the fixed plate facing the material roll. The output end of the cylinder b is vertically connected to the receiving plate through the connecting plate, and the side of the connecting plate is perpendicular to the upper side wall of the receiving plate.

[0015] By adopting the above technical solution, after the rotary cylinder rotates 90°, cylinder b drives the connecting plate, and the connecting plate moves the receiving plate away from the fixed plate, so that the end of the receiving plate is closer to the end of the material head. In this way, when the material head and the material tail are welded in the next step, the material head has rigidity and will not sag, which facilitates welding.

[0016] Preferably, the detection structure is located on the fixed plate between the cylinders b. The detection structure includes a cylinder c. The output end of the cylinder c is rotatably connected to one end of a T-shaped plate. The other end of the T-shaped plate is connected to a detection bracket. A photoelectric sensor is installed inside the detection bracket. The bottom of the T-shaped plate is connected to the side wall of the fixed plate through a rotating shaft. The photoelectric sensor rotates counterclockwise around the rotating shaft. The photoelectric sensor is located at the lower edge of the receiving plate.

[0017] By adopting the above technical solution, when the signal of the photoelectric sensor is blocked by the material head, the material roll stops feeding and the cylinder a is controlled to retract the moving plate, so that the moving plate and the fixed plate clamp the material head.

[0018] Preferably, the top of the support plate is provided with a vertically upward guide rail a, and a base is provided on one side of the guide rail a via a slider a. The output end of the cylinder d is connected to the base, the cylinder d is connected to the frame, and the base is fixed by a connecting plate and a connecting block.

[0019] By adopting the above technical solution, the base can be driven by the cylinder d, which can make the clamping device move up and down as a whole to adapt to the clamping work of the moving plate and the fixed plate on the material head, and the subsequent welding work of the material head and the material tail.

[0020] Preferably, the connecting block is connected to the guide rail b via the slider b, the guide rail b is located on the substrate, the substrate is connected to the frame, and the substrate is perpendicular to the guide rail a in space.

[0021] Preferably, a motor is provided at one end of the substrate, and the output end of the motor is connected to the bearing at the end of the substrate through a lead screw passing through the connecting block. The connecting block and the lead screw are adapted to each other, and the bottom of the connecting block is fixedly connected to the slider b.

[0022] By adopting the above technical solution, the motor drives the lead screw to drive the connecting block, and the connecting block drives the slider b to move laterally on the guide rail b. This can be adapted to the clamping work of the moving plate and the fixed plate on the material head, and the subsequent welding work of the material head and the material tail.

[0023] The advantages of this utility model are as follows: 1. By setting a guide plate below the material head, the position of the guide plate is moved when the material head is drooping, so that the guide plate is always located on the outside of the material head, which helps the material head to continue to descend between the moving plate and the fixed plate, making it easier for the moving plate and the fixed plate to clamp it.

[0024] 2. By using a receiving plate, this utility model can make the part of the material head exposed on the receiving plate have rigidity when welding the material head and the material position of the next process, so as to avoid the material head sagging and there is no overlap between the material head and the material tail, thereby increasing the welding efficiency.

[0025] 3. This utility model uses a displacement device to facilitate the pressing of the material head by the moving plate and the fixed plate, as well as the welding work of the material head and the material tail in the subsequent process after the rotation is completed, thereby improving the overall adaptability of the device.

[0026] 4. This utility model optimizes the material loading and changing process, shortens the process time, improves the overall production capacity, and facilitates the arrangement and allocation of personnel. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0034] like Figure 1-5As shown, the intelligent EVA feed head finding device includes a displacement device, a clamping device, and a detection structure. The clamping device is located below the feed roll 1, and the displacement device is located above the feed roll 1. The clamping device includes a fixed plate 3, a moving plate 4, a receiving plate 6, and a guide plate 402. The receiving plate 6 is located inside the fixed plate 3, and the moving plate 4 is located on one side of the fixed plate 3. The displacement device includes a guide rail and a base plate 24 connected to the clamping device. A driving structure is provided on the base plate. The detection structure is located inside the feed roll 1. When the feed roll 1 is unloaded, the displacement device adjusts the clamping device, and then the moving plate 4 moves away from the fixed plate 3. The feed head is located inside the guide plate 402. The feed continues until it enters between the moving plate 4 and the fixed plate 3. After being detected by the detection structure, the moving plate 4 closes towards the fixed plate 3 to press the feed head. Then, the rotary cylinder 14 rotates 90° away from the feed roll 1, allowing the feed head to enter the next process.

[0035] The clamping device is located between the clamping plates 2 and below the drive unit connecting the material roll 1 and the clamping plate 2. The material head of the material roll 1 is fed upward toward the clamping device. The fixed plate 3 has inverted L-shaped support plates 16 at both ends. The inner side of the support plate 16 is connected to the rotating rod 15 through the rotary cylinder 14. The fixed plate 3 is fixed on the rotating rod 15. The fixed plate is equipped with a cylinder a5. The output end of the cylinder a5 passes through the fixed plate 3 and is connected to the moving plate 4. The fixed plate 3 can be rotated as a whole through the rotary cylinder 14 and the rotating rod 15 to adapt to the next process. The moving plate 4 extends through the drive of the cylinder a5. When the material head passes through, the cylinder a5 retracts and the moving plate 4 clamps the material head.

[0036] The bottom of the fixed plate 3 is provided with an upward-facing groove 301. The groove 301 does not penetrate the top of the fixed plate 3. The receiving plate 6 is convex upward in shape. The receiving plate 6 fits perfectly into the groove 301. The two sides of the receiving plate 6 are located inside the fixed plate 3. The receiving plate 6 and the fixed plate 3 are on the same plane. The moving plate 4 is close to the fixed plate 3. The moving plate 4 is driven by the cylinder a5 on the fixed plate 3 and extends outward. When the whole device rotates, the receiving plate 6 can make the material head spread flat on the receiving plate 6 for the next step and the material position to be welded, so that the material head does not face downward.

[0037] The inner surface of the moving plate 4 is provided with an inward rectangular groove 401. The guide plate 402 is located in the rectangular groove 401. The rectangular groove 401 does not penetrate the bottom and outer side of the moving plate 4. The guide plate 402 is located in the rectangular groove 401 and is in the same plane as the moving plate 4. The part of the guide plate 402 located on the outer side of the moving plate 4 is inclined outward. When the material roll 1 is unloaded, the material roll 1 is located on the inner side of the guide plate 402. When the material head is unloaded, the guide plate 402 can guide the material head, so that the material head is unloaded between the moving plate 4 and the fixed plate 3 under the action of the guide plate 402. The guide plate 402 can prevent the material head from being unloaded outward and accurately enter the position between the moving plate 4 and the fixed plate 3.

[0038] On one side of the fixed plate 3 facing the material roll 1, there are cylinders b7 on both sides. The output end of the cylinder b7 is vertically connected to the receiving plate 6 through the connecting plate 8. The side of the connecting plate 8 is perpendicular to the upper side wall of the receiving plate 6. When the rotating cylinder 14 rotates 90°, the cylinder b7 drives the connecting plate, and the connecting plate 8 drives the receiving plate 6 away from the fixed plate 3, so that the end of the receiving plate 6 is closer to the end of the material head. In this way, when the material head and the material tail are welded in the next step, the material head has rigidity and will not sag, which facilitates the welding.

[0039] The detection structure is located on the fixed plate 3 between cylinders b7. The detection structure includes cylinder c9. The output end of cylinder c9 is rotatably connected to one end of T-shaped plate 10, and the other end of T-shaped plate 10 is connected to detection bracket 11. Photoelectric sensor 13 is installed inside detection bracket 11. The bottom of T-shaped plate 10 is connected to the side wall of fixed plate 3 through rotating shaft 12. Photoelectric sensor 13 rotates counterclockwise around rotating shaft 12. Photoelectric sensor 13 is located at the lower edge of receiving plate 6. The transmitting end of photoelectric sensor 13 has a corresponding receiving end located outside the material head. When the signal of photoelectric sensor 13 is blocked by the material head, it indicates that the material head has been blocked. The length of the material head exceeds the receiving plate 6. The photoelectric sensor 13 can be placed at a position corresponding to the distance from the receiving plate 6 according to actual needs. The photoelectric sensor 13 and all cylinders and motors in the device are connected to an external controller, which is a conventional method in the art. When the receiving end does not receive the signal from the photoelectric sensor 13, the controller controls the clamping plate 2 to stop feeding. The method of the clamping plate 2 feeding the material roll 1 is a conventional method in the art. The material roll 1 stops feeding, and the cylinder a5 is controlled to retract the moving plate 4, so that the moving plate 4 and the fixed plate 3 clamp the material head.

[0040] The top of the support plate 6 is provided with a vertically upward guide rail a17. A base 20 is provided on one side of the guide rail a17 via a slider a19. The output end of the cylinder d18 is connected to the base 20. The cylinder d18 is connected to the frame. The base 20 is fixed by the connecting plate 22 and the connecting block 23. The base 20 is driven by the cylinder d21, which can make the clamping device move up and down as a whole to adapt to the clamping work of the moving plate 4 and the fixed plate 3 on the material head, and the subsequent welding work of the material head and the material tail.

[0041] The connecting block 23 is connected to the guide rail b28 via the slider b25. The guide rail b28 is located on the base plate 24, which is connected to the frame. The base plate 24 is perpendicular to the guide rail a17 in space. A motor 26 is provided at one end of the base plate 24. The output end of the motor 26 is connected to the bearing at the end of the connecting block 23 and the base plate 24 via the lead screw 27. The connecting block 23 and the lead screw 27 are adapted to each other. The bottom of the connecting block 23 is fixedly connected to the slider b25. The motor 26 drives the lead screw 27 to move the connecting block 23. The connecting block 23 drives the slider b25 to move laterally on the guide rail b28. This can be adapted to the clamping work of the moving plate 4 and the fixed plate 3 on the material head, and the subsequent welding work of the material head and the material tail.

[0042] When material roll 1 is unloaded, the head of material roll 1 faces downwards. Drive motor 26 and cylinder d21 so that the head of material falls exactly inside the guide plate 402. The guide plate 402 and the moving plate 4 are fixed together by bolts. Cylinder a5 drives the moving plate 4 away from the fixed plate 3. When the head of material falls between the two and continues to descend, when the signal of photoelectric sensor 13 is blocked, the moving plate 4 moves closer to the fixed plate 3, so that the head of material is clamped. Rotary cylinder 14 rotates the whole in a direction away from material roll 1 by 90°. Then cylinder b7 drives the receiving plate 6 so that the end of the receiving plate 6 is close to the head of material. At the same time, drive motor 2 and cylinder d21 adjust the position of the receiving plate 6 so that the part of the head of material exposed on the receiving plate 6 is in a rigid state, which facilitates the welding work of the tail and head of material in the next process.
