Description

Technical Field

[0001] This utility model relates to the technical field of material roll supply systems, and in particular to an automatic material changing auxiliary device for a material roll supply system. Background Technology

[0002] Battery separator paper is a key material in battery manufacturing. Its core function is to physically isolate the positive and negative electrodes of the battery, preventing direct contact between the two electrodes and thus preventing short circuits, thereby ensuring the battery's safety and electrochemical performance. In the production process of alkaline batteries, battery separator paper is usually stored in reels and automatically fed through a paper roll supply system. Specifically, the separator paper reel is mounted on a rotating shaft of the supply system and is drawn to the separator paper station by guide rollers. As the station continuously consumes separator paper, the reel is continuously unwound, achieving continuous supply.

[0003] When the release liner on the spindle is depleted, the machine must be stopped to replace it with a new one. Currently, mainstream paper roll supply systems still rely on manual operation: workers observe the remaining amount on the liner, manually remove the depleted liner, and install a new one. This manual intervention method has significant drawbacks: 1. Low efficiency: Manual monitoring and replacement require frequent downtime, affecting production continuity. Especially in high-speed production lines, downtime directly impacts capacity. 2. High labor costs: Requires dedicated personnel, increasing labor input; 3. Risk of misjudgment: Manual observation may be delayed or misjudged, leading to paper supply interruption or material waste.

[0004] To improve automation levels, there is an urgent need to develop an intelligent supply system that can be automated for roll changing and splicing with robot assistance. The ends of brand-new paper rolls are usually secured with adhesive tape. After the new paper roll is installed on the rotating shaft of the supply system, the adhesive tape at the roll end must be peeled off before the roll can be released for threading and splicing. One of the key technical challenges in using a robot-assisted roll changing intelligent supply system is how to prevent the paper roll from loosening when the robot peels off the adhesive tape from the rotating shaft, thus ensuring operational reliability.

[0006] The technical solution to achieve the purpose of this utility model is: an automatic material changing auxiliary device for a material roll supply system, including a machine plate, on which a rotating shaft for installing material rolls is mounted, and a material roll stabilizing mechanism is provided on one side of the rotating shaft. The material roll stabilizing mechanism includes a side limiting plate and an end limiting plate. The side limiting plate is hinged to the machine plate and is located radially on the material roll on the rotating shaft.

[0007] Furthermore, the push rod is a screw rod, which passes through a threaded hole on the bracket and is threadedly assembled with the bracket; in the first rotational position, the push rod faces the side limiting plate. The push rod can be a top block on the bracket or a screw rod threadedly assembled with the bracket. When the push rod is a screw rod threadedly assembled with the bracket, the top pressure between the push rod and the side limiting plate, and between the side limiting plate and the rotating shaft on the feed coil, can be easily adjusted by rotating the screw rod.

[0008] Furthermore, the bracket includes an L-shaped main body and a support extending from one end of the L-shaped main body towards the side of the machine plate.

[0011] Furthermore, the rotation center of the side limiting plate is located between the rotation center of the end limiting plate and the rotating shaft.

[0012] Furthermore, the rotation axis of the end limiting plate, the hinge axis of the side limiting plate, and the rotation axis are all parallel.

The material roll stabilizing mechanism 2 includes a side limiting plate 21 and an end limiting plate 22. The side limiting plate 21 is hinged to the machine plate 10 and is located radially on the material roll 100 on the rotating shaft 1. The end limiting plate 22 is mounted on a rotating mechanism 20 and is rotatable by the rotating mechanism 20. The end limiting plate 22 and the material roll 100 on the rotating shaft 1 are parallel to each other. The end limiting plate 22 is located on the axially offset distribution of the rotating shaft 1, outside the end of the material roll 100 on the rotating shaft 1 away from the machine plate 10 and close to the material roll 100. The distance from the top of the end limiting plate 22 to the rotation center P1 of the end limiting plate 22 is D1, and the distance from the rotation center P1 of the end limiting plate 22 to the peripheral wall of the material roll 100 on the rotating shaft 1 is D2. The relationship between D1 and D2 satisfies D1>D2. A bracket 23 is also installed on the end limiting plate 22. The bracket 23 is provided with a top rod 24 and a pulling block 25. The side limiting plate 21 is located between the top rod 24 and the pulling block 25. The rotating mechanism 20 has a first rotating position and a second rotating position; In the first rotational position, the side limiting plate 21 is located between the top rod 24 and the material roll 100 on the rotating shaft 1.

[0020] This utility model relates to an automatic material changing auxiliary device for a material roll supply system. The rotating shaft 1 is rotatably mounted on the machine plate 10 and is used to mount material rolls 100. The material rolls 100 mounted on the rotating shaft 1 supply the material to the workstation. The material roll stabilizing mechanism 2 is used to limit and stabilize the new material rolls 100 mounted on the rotating shaft 1, so that when the robot peels off the adhesive on the new material rolls 100, the material rolls 100 will not axially sway, and after the adhesive is peeled off, the ends of the material rolls 100 will hang naturally without loosening.

[0021] In this utility model, an automatic material changing auxiliary device for a material roll supply system includes a material roll stabilizing mechanism 2. A side limiting plate 21 is hinged to the machine plate 10 via a pin 211 and is rotatable around the pin 211. The side limiting plate 21 is located radially on the material roll 100 on the rotating shaft 1, and along the axial direction of the rotating shaft 1, the side limiting plate 21 and the material roll 100 on the rotating shaft 1 are directly opposite each other without misalignment. An end limiting plate 22 and the material roll 100 on the rotating shaft 1 are offset along an axial direction parallel to the rotating shaft 1. The end limiting plate 22 and the material roll 100 on the rotating shaft 1 have a small gap along this axial direction, and the end limiting plate 22 is close to the material roll 100. The bracket 23 is installed on the end limiting plate 22. The top rod 24 and the pull block 25 are provided on the bracket 23. The end limiting plate 22 is installed on a rotating mechanism 20. When the rotating mechanism 20 drives the plate to rotate, the bracket 23 and the top rod 24 and the pull block 25 on it rotate together. During the rotation, the top rod 24 and the pull block 25 will also push the side limiting plate 21, causing the side limiting plate 21 to rotate.

[0022] The automatic material changing auxiliary device of the material roll supply system of this utility model has the following features: the rotation path of the top of the side limiting plate 21 is an arc L1, the first end of the arc L1 is located on the outer circle of the material roll 100 on the rotating shaft 1, and the second end of the arc L1 is located outside the outer circle of the material roll 100 on the rotating shaft 1; the projection of the rotation path of the top of the end limiting plate 22 onto the plane where the material roll 100 is located on the rotating shaft 1 is an arc L2, the first end of the arc L2 is located inside the outer circle of the material roll 100 on the rotating shaft 1, and the second end of the arc L2 is located outside the outer circle of the material roll 100 on the rotating shaft 1. The rotating mechanism 20 has a first rotating position and a second rotating position.

[0023] This utility model's automatic material changing auxiliary device for a material roll supply system utilizes a robot to peel off the adhesive on a brand-new material roll 100. The rotating mechanism 20 drives the end limiting plate 22 and its support 23 to rotate. During rotation, the top rod 24 drives the side limiting plate 21, causing it to rotate. The peripheral wall of the material roll 100 on the rotating shaft 1 contacts the side limiting plate 21 until it reaches the first rotation position. Figures 6 to 8 As shown, the top rod 24 sequentially presses the side limiting plate 21 and the material roll 100 on the rotating shaft 1 together, and the material roll 100 with its circumferential wall pressed together can be circumferentially limited to prevent the material roll 100 from loosening after the adhesive is torn off; the end limiting plate 22 rotates to be opposite to the end face of the material roll 100, and limits the axial direction of the material roll 100 on the rotating shaft 1 to prevent the material roll 100 from axially swinging outward during the process of tearing off the adhesive.

[0024] This utility model's automatic material changing auxiliary device for a material roll supply system, after adhesive application, when the material roll 100 is threaded onto the roller, is driven by the rotating mechanism 20, which causes the end limiting plate 22 and its support 23 to rotate in the opposite direction. During rotation, the pulling block 25 drives the side limiting plate 21, causing the side limiting plate 21 to rotate and move away from the material roll 100 on the rotating shaft 1, until it rotates to the second rotation position, such as... Figures 2 to 5 As shown, the pull block 25 contacts the side limiting plate 21. The side limiting plate 21 and the end limiting plate 22 are both located on the circumferential outer side of the loading roll 100 of the rotating shaft 1, thus achieving reset. At the same time, the limiting of the loading roll 100 of the rotating shaft 1 is released.

[0025] The automatic material changing auxiliary device of this utility model material roll supply system limits the circumferential and axial directions of the material roll 100 on the rotating shaft 1 by setting the side limiting plate 21 and the end limiting plate 22. This assists the operation of the robot when the robot peels off the adhesive on the new material roll 100, preventing the material roll 100 from becoming loose and axially swaying after the adhesive is peeled off. This ensures the reliability of the robot's automatic roll changing and adhesive peeling operation, and lays the foundation for intelligent supply with automatic roll changing and splicing.

[0026] The automatic material changing auxiliary device of the material roll supply system of this utility model has the side limiting plate 21 and the end limiting plate 22 driven by the same rotating mechanism 20, which can realize the limiting operation at different positions. Its design is simple, easy to manufacture and install, and reduces the complexity and cost of the equipment.
