Description

Technical Field

[0001] This utility model relates to the technical field of paper roll supply systems, and in particular to an automatic paper receiving device for a paper 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. Battery separator paper is a microporous and porous film, primarily made of PP and PE. 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 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, then install a new liner and re-feed the paper. 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 capable of automatically changing and reconnecting reels. One of the technical challenges in implementing this system lies in how to connect the new release paper to the original cut point after the depleted release paper has been cut, removed, and replaced with a new roll of material, thus completing the reconnection. Utility Model Content

[0005] The purpose of this invention is to provide an automatic paper receiving device for a paper roll supply system.

[0006] The technical solution to achieve the purpose of this utility model is: an automatic paper receiving device for a paper roll supply system, comprising a heating block, a pressure block, a top block, and a clamping mechanism. The heating block is mounted on a first lifting mechanism and is movable up and down by the first lifting mechanism. The pressure block is mounted on a second lifting mechanism and is movable up and down by the second lifting mechanism. The heating block and the pressure block are both located directly above the top block. The top block is located on the lifting path of the heating block and the pressure block. The clamping mechanism is mounted on a first linear moving mechanism and is movable linearly by the first linear moving mechanism. The moving path of the clamping mechanism is horizontally set. The clamping mechanism and the top block are arranged horizontally along a direction parallel to the moving path of the clamping mechanism. The heating block and the pressure block are also arranged horizontally along a direction parallel to the moving path of the clamping mechanism. The heating block is located between the pressure block and the clamping mechanism.

[0007] Furthermore, a first hole is formed on the heating block, and a thermocouple is installed in the first hole. During operation, the thermocouple is energized to generate heat, which is then transferred to the heating block.

[0008] Furthermore, a second hole is provided on the heating block, and a temperature sensor is installed in the second hole. The temperature sensor detects the temperature of the heating block in real time, facilitating intelligent temperature control of the heating block.

[0009] Furthermore, a protruding ridge extends downwards from one side of the bottom of the heating block. This ridge is elongated, and its length direction is parallel to the width direction of the release liner. When the exhausted roll is cut, replaced, or reconnected, the joint of the release liner is elongated along its width direction. The protruding ridge presses against the joint to heat-fuse and bond it, completing the connection. The protruding ridge serves two purposes: firstly, it reduces the heat-fusion surface area, adapting to the size of the release liner joint; secondly, under the same force, the smaller area of ​​the protruding ridge results in greater pressure, leading to better heat-fusion efficiency and a stronger connection.

[0010] Furthermore, the heating block is mounted on the first lifting mechanism via a mounting bracket. The mounting bracket is fixedly connected to the first lifting mechanism. A vertical through hole is provided on the mounting bracket, and a screw that is movably assembled with the mounting bracket passes through the vertical through hole. The upper end of the screw has a nut. The heating block is fixedly mounted on the lower end of the screw. A compression spring is sleeved on the screw. The upper end of the compression spring contacts the mounting bracket, and the lower end contacts the heating block. This design has two advantages. First, when the heating block moves towards the top block and abuts against it to heat-fuse the release liner joint between the heating block and the top block, the heating block and the top block are subjected to force. After being subjected to force, the compression spring can compress and deform, absorbing the force through deformation and buffering the force to reduce the impact between the heating block and the top block. Second, when the heating block abuts against the top block, the compression spring also ensures that the heating block always exerts a force on the top block. This force makes the abutment between the heating block and the top block more compact, and the heat-fusing efficiency of the release liner joint is better.

[0011] Furthermore, the mounting bracket has two vertical through holes, each corresponding to a screw, and the heating block is mounted on all of the screws. With the two screws, the two screws limit the circumferential movement of the heating block, preventing it from rotating.

[0012] Furthermore, a silicone plate is installed at the bottom of the pressure block. When the pressure block presses the paper down, the silicone plate comes into contact with the release paper. The silicone plate increases the friction between the silicone plate and the paper, making the paper pressing more reliable.

[0013] Furthermore, the top block is provided with a negative pressure chamber, and air holes are formed on the upper surface of the top block, communicating with the negative pressure chamber. An air extraction port is also installed on the top block, communicating with the negative pressure chamber. During paper splicing, the air extraction port is connected to a negative pressure machine, which draws air from the chamber, using the negative pressure within the negative pressure chamber to adsorb the release paper joints stacked on the top block onto its surface. This design allows for greater flatness of the release paper joints, and during heat fusion, the stacked release paper structure is more stable and reliable.

[0014] Furthermore, the number of pores is several, and the several pores are evenly distributed.

[0015] Furthermore, the clamping mechanism is an electric gripper or a pneumatic finger.

[0016] Furthermore, it also includes a water spray head, which is mounted on a second linear moving mechanism and can move linearly driven by the second linear moving mechanism. The moving path of the water spray head is horizontally set and perpendicular to the moving path of the clamping mechanism. The water spray head is located above the moving path of the clamping mechanism, between the clamping mechanism and the heating block. During the process of the clamping mechanism moving one end of the release paper towards the pressure block and overlapping with the other end of the release paper on the pressure block, the clamping mechanism moves the one end of the release paper held by the release paper to the water spray head. The second linear moving mechanism then drives the water spray head to move along the width direction of the release paper. During the movement, the water spray head sprays water mist, wetting the release paper end held by the clamping mechanism. After the release paper end is wetted, when the two ends are heat-fused together, the humidity of the heat-fusion process is increased, effectively preventing the release paper end from drying and charring at high temperatures. This also improves the heat-fusion bonding effect of the release paper end, resulting in a stronger bond after connection.

[0017] Furthermore, the first lifting mechanism, the second lifting mechanism, the first linear motion mechanism, and the second linear motion mechanism are all cylinders. These mechanisms can be linear mechanisms with motor-driven lead screws, or they can be cylinders, such as rod-type cylinders or rodless linear cylinders. Compared to the former, cylinders have a simpler structure and higher operational stability.

[0018] This utility model relates to an automatic paper feeding device for a paper roll supply system. The device uses a pressure block to fix one of the paper separators to be connected to a top block. The clamping mechanism clamps another paper separator to be connected and sends it to the top block, so that the two paper separators to be connected are stacked together. Then, the heating block heats the two stacked paper separators, causing them to melt and bond together, thereby achieving automatic connection and laying the foundation for continuous feeding of the intelligent supply system.

Detailed Implementation

[0020] The preferred embodiment of the automatic paper receiving device of the paper roll supply system of this utility model will be described in detail below with reference to the accompanying drawings: like Figures 1 to 7 As shown, an automatic paper receiving device for a paper roll supply system includes a heating block 1, a pressure block 2, a top block 3, and a clamping mechanism 4. The heating block 1 is mounted on a first lifting mechanism 10 and can be raised and lowered by the first lifting mechanism 10. The pressure block 2 is mounted on a second lifting mechanism 20 and can be raised and lowered by the second lifting mechanism 20. The heating block 1 and the pressure block 2 are both located directly above the top block 3. The top block 3 is located on the lifting path of the heating block 1 and the pressure block 2. The clamping mechanism 4 is mounted on a first linear moving mechanism 40 and can move linearly by the first linear moving mechanism 40. The moving path of the clamping mechanism 4 is horizontally set. The clamping mechanism 4 and the top block 3 are arranged horizontally along a direction parallel to the moving path of the clamping mechanism 4. The heating block 1 and the pressure block 2 are also arranged horizontally along a direction parallel to the moving path of the clamping mechanism 4. The heating block 1 is located between the pressure block 2 and the clamping mechanism 4.

[0021] This utility model relates to an automatic paper receiving device for a paper roll supply system. The pressure block 2 is located above and opposite the top block 3. When the pressure block 2 is pressed down by the second lifting mechanism 20, it can press and secure the release paper connector placed on the top block 3. The clamping mechanism 4 is used to clamp another release paper connector to be connected. The clamping mechanism 4 and the top block 3 are horizontally arranged along a direction parallel to the moving path of the clamping mechanism 4. Under the drive of the first linear moving mechanism 40, the clamping mechanism 4 can reciprocate towards or away from the top block 3. For example, when moving towards the top block 3, it stacks the other release paper connector 100' clamped on the clamping mechanism 4 with the release paper connector 100 on the top block 3. The heating block 1 is located above and opposite the top block 3. When the heating block 1 is pressed down by the first lifting mechanism 10, it heat-fuses and bonds the two release paper connectors stacked on the top block 3.

[0022] This utility model relates to an automatic paper receiving device for a paper roll supply system. When connecting the two ends of the release liner, one release liner end is placed on the top block 3. The pressure block 2, driven by the second lifting mechanism 20, presses down to secure the release liner end on the top block 3. The other release liner end is clamped on the clamping mechanism 4, which, driven by the first linear movement mechanism 40, moves towards the side closer to the top block 3, stacking the release liner end clamped on the clamping mechanism 4 with the release liner end on the top block 3. Then, the heating block 1, driven by the first lifting mechanism 10, presses down to heat-melt the two stacked release liner ends on the top block 3, achieving adhesion and connection. After connection, the clamping mechanism 4 opens, and the heating block 1, the pressure block 2, and the clamping mechanism 4, driven by the first linear movement mechanism 40, respectively reset.

[0023] The automatic paper-connecting device of this utility model paper roll supply system has a pressing block 2 that fixes one of the isolation paper joints to be connected to the top block 3. The clamping mechanism 4 clamps the other isolation paper joint to be connected and sends it to the top block 3, so that the two isolation paper joints to be connected are stacked together. Then, the heating block 1 heats the two stacked isolation paper joints, so that the two isolation paper joints are heated and melted and bonded, thereby realizing automatic connection and laying the foundation for continuous material supply of the intelligent supply system.

[0024] In this utility model, the automatic paper receiving device of the paper roll supply system preferably has a first hole 11 on the heating block 1, and a thermocouple 111 is installed in the first hole 11. During operation, the thermocouple 111 is energized to generate heat, which is transferred to the heating block 1.

[0025] In this invention, the automatic paper receiving device of the paper roll supply system preferably includes a second hole 12 on the heating block 1, and a temperature sensor 121 installed in the second hole 12. The temperature sensor 121 detects the temperature of the heating block 1 in real time, facilitating intelligent temperature control of the heating block 1.

[0026] In this utility model, the automatic paper feeding device of the paper roll supply system preferably has a protruding ridge 13 extending downward from one side of the bottom of the heating block 1. The protruding ridge 13 is elongated, and its length direction is parallel to the width direction of the release paper. When the exhausted roll is cut and replaced or continued, the joint of the release paper is elongated along its width direction. The protruding ridge 13 presses against the joint to heat-fuse and bond it, thus completing the connection. The protruding ridge 13 has two advantages: firstly, it reduces the heat-fusion surface area, adapting to the size of the release paper joint; secondly, under the same force, the smaller area of ​​the protruding ridge 13 results in greater pressure, better heat-fusion efficiency of the release paper joint, and a more secure connection.

[0027] In a preferred embodiment of the automatic paper receiving device of the paper roll supply system of this utility model, the heating block 1 is mounted on the first lifting mechanism 10 via a mounting bracket 14. The mounting bracket 14 is fixedly connected to the first lifting mechanism 10. A vertical through hole 141 is provided on the mounting bracket 14, and a screw 15 is movably assembled with the mounting bracket 14 through the vertical through hole 141. The upper end of the screw 15 has a nut 151. The heating block 1 is fixedly mounted on the lower end of the screw 15. A compression spring 16 is sleeved on the screw 15. The upper end of the compression spring 16 contacts the mounting bracket 14, and the lower end contacts the heating block 1. This configuration has two advantages. First, when the heating block 1 moves towards the top block 3 and abuts against the top block 3 to heat-fuse the insulating paper joint between the heating block 1 and the top block 3, the heating block 1 and the top block 3 are subjected to force. After being subjected to force, the compression spring 16 can be compressed and deformed to absorb the force and buffer the impact between the heating block 1 and the top block 3. Second, when the heating block 1 and the top block 3 are abutting, the compression spring 16 also ensures that the heating block 1 always has a force acting on the top block 3. This force makes the abutment between the heating block 1 and the top block 3 more compact, and the heat-fusing efficiency of the insulating paper joint by the heating block 1 is better.

[0028] In this utility model, the automatic paper receiving device for a paper roll supply system preferably has two vertical through holes 141 on the mounting frame 14, each of which is respectively provided with a screw 15. The heating block 1 is mounted on all of the screws 15. With the two screws 15, the two screws 15 limit the circumferential movement of the heating block 1, preventing the heating block 1 from rotating.

[0029] In this utility model's automatic paper receiving device for a paper roll supply system, preferably, a silicone plate 21 is installed at the bottom of the pressure block 2. When the pressure block 2 presses the paper downwards, the silicone plate 21 comes into contact with the release paper. The silicone plate 21 increases the friction between the silicone plate and the paper, making the paper pressing more reliable.

[0030] In this utility model, an automatic paper receiving device for a paper roll supply system preferably includes a negative pressure chamber 31 within the top block 3. An air hole 32 is formed on the upper surface of the top block 3, communicating with the negative pressure chamber 31. An air extraction port 33 is also installed on the top block 3, communicating with the negative pressure chamber 31. During paper receiving, the air extraction port 33 is connected to a negative pressure machine, which draws air from the chamber, creating negative pressure within the negative pressure chamber 31. This causes the release liner stacked on the top block 3 to be adsorbed onto the surface of the top block 3. This design allows for a higher flatness of the release liner stack, and during heat fusion, the stacked structure of the release liner is more stable and reliable.

[0031] In the automatic paper receiving device of the paper roll supply system of this utility model, preferably, the number of air holes 32 is several, and the several air holes 32 are evenly distributed.

[0032] In this utility model's automatic paper receiving device for a paper roll supply system, preferably, the clamping mechanism 4 is an electric gripper or a pneumatic finger. Alternatively, the clamping part of the clamping mechanism 4 may also be equipped with a silicone plate to increase friction.

[0033] The automatic paper receiving device of this utility model paper roll supply system preferably includes a water spray head 5. The water spray head 5 is mounted on a second linear moving mechanism 50 and can move linearly driven by the second linear moving mechanism 50. The moving path of the water spray head 5 is horizontally set and perpendicular to the moving path of the clamping mechanism 4. The water spray head 5 is located above the moving path of the clamping mechanism 4 and between the clamping mechanism 4 and the heating block 1. When the clamping mechanism 4 moves one end of the release paper towards the pressure block 2 and overlaps with the other end of the release paper on the pressure block 2, the one end of the release paper held by the clamping mechanism 4 moves to the water spray head 5. The second linear moving mechanism 50 drives the water spray head 5 to move along the width direction of the release paper. During the movement, the water spray head 5 sprays water mist to wet the release paper end held by the clamping mechanism 4. When the insulating paper joint is moistened, the humidity can be increased during the heat fusion connection of the two joints. This effectively prevents the insulating paper joint from drying and charring at high temperatures, while also improving the heat fusion bonding effect and resulting in a stronger connection.

[0034] In this utility model's automatic paper receiving device for a paper roll supply system, preferably, the first lifting mechanism 10, the second lifting mechanism 20, the first linear movement mechanism 40, and the second linear movement mechanism 50 are all cylinders. The structures of the first lifting mechanism 10, the second lifting mechanism 20, the first linear movement mechanism 40, and the second linear movement mechanism 50 can be linear mechanisms driven by motor-driven lead screws, or they can be cylinders, such as rod-type cylinders or rodless linear cylinders. Compared to the former, cylinders have a simpler structure and higher operational stability.

[0035] This utility model relates to an automatic paper receiving device for a paper roll supply system. The first lifting mechanism 10, the second lifting mechanism 20, the first linear movement mechanism 40, the second linear movement mechanism 50, the thermocouple 111, the temperature sensor 121, and the water spray head 5 are all electrically connected to a control unit, forming an automatic control system with the control unit to achieve automatic control. The water spray head, cylinder, thermocouple, temperature sensor, negative pressure unit, and the aforementioned control system are all existing technologies, and will not be elaborated upon further in this utility model.

[0036] For those skilled in the art to which this utility model pertains, several simple deductions or substitutions can be made without departing from the concept of this utility model, and all such deductions or substitutions should be considered to fall within the protection scope of this utility model.
