Description

Technical Field

[0001] This utility model belongs to the technical field of feeding equipment, specifically a feeding device for hot pressing foam tape. Background Technology

[0002] Foam tape is made by coating one or both sides of EVA or PE foam with solvent-based (or hot-melt) pressure-sensitive adhesive and then covering it with release paper. It has the functions of sealing and shock absorption. However, in the thermoforming production process of foam tape, a feeding device is required to feed the wound substrate into rolls. The wound substrate is usually wound on a roller for feeding. Traditional foam tape feeding devices require manual handling and lifting when placing the rolled substrate on the device. Manual installation is prone to injury to workers due to slippage, and the installation is time-consuming and labor-intensive. In addition, the foam tape is easily pulled and broken during the feeding process, resulting in losses. Therefore, improvements are needed to address the above problems. Utility Model Content

[0003] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for hot pressing foam tape, comprising a U-shaped base, a pair of rotating lifting arms rotatably mounted on the top of each end of the U-shaped base, a U-shaped support block rotatably mounted between the tops of each pair of rotating lifting arms, two rollers rotatably mounted on opposite sides of each pair of U-shaped support blocks, a roller mounted between the interior of the two U-shaped support blocks, the roller being located between the four rollers and capable of rotational adjustment, an adjusting arm rotatably mounted on the lower part of one of the rotating lifting arms in each pair, a connecting block rotatably connected to the bottom of each of the two adjusting arms, a horizontally adjustable movable seat mounted inside the U-shaped base, and two connecting blocks fixedly mounted on the top ends of the movable seat.

The U-shaped base is rotatably connected to a threaded shaft, which is threaded to the middle of the movable seat. The U-shaped base is also equipped with a lifting motor, and the output end of the motor is fixedly connected to one end of the threaded shaft. This allows for effective adjustment of the two U-shaped support blocks to lift the roll and the substrate wound on its surface.

[0005] Preferably, one end of one of the rollers on the two U-shaped support blocks is fixedly mounted with a gear A, and the top of both ends of the U-shaped base is fixedly mounted with a vertical plate.

A chain is installed between adjacent sprockets A and sprockets B, so as to effectively adjust the rotation of the roll and the roll material on it, so that the roll drives the roll material to rotate and feed.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: This feeding device has a lifting and feeding structure and a transmission feeding structure.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Depend on Figures 1 to 4 The present invention includes a U-shaped base 1, with a pair of rotating lifting arms 2 rotatably mounted on the top of each end of the U-shaped base 1. A U-shaped support block 3 is rotatably mounted between the tops of each pair of rotating lifting arms 2. Two rollers 4 are rotatably mounted on opposite sides of the two U-shaped support blocks 3. A roller 5 is installed between the interiors of the two U-shaped support blocks 3. The surface of the roller 5 is wound with a substrate, and the roller 5 is located between the four rollers 4 and can be rotated and adjusted. An adjusting arm 6 is rotatably mounted on the lower part of one of the rotating lifting arms 2 in each pair. A connecting block 7 is rotatably connected to the bottom of each of the two adjusting arms 6. A horizontally adjustable movable seat 8 is installed inside the U-shaped base 1, and the two connecting blocks 7 are fixedly mounted on the top ends of the movable seat 8.

[0017] The U-shaped base 1 has horizontal grooves 9 on both sides inside. The movable seat 8 is installed between the two horizontal grooves 9, and the ends of the movable seat 8 inside the two horizontal grooves 9 are equipped with movable wheels 10. The U-shaped base 1 is rotatably connected to a threaded shaft 11, which is threaded to the middle of the movable seat 8. The U-shaped base 1 is also equipped with a lifting motor 12, and the output end of the motor 12 is fixedly connected to one end of the threaded shaft 11. This allows for effective adjustment of the two U-shaped support blocks 3 to lift the roll 5 and the substrate wound on its surface.

[0018] In use, the threaded shaft 11 is rotated by starting the motor 12. The rotation of the threaded shaft 11 will cause the moving seat 8 to move horizontally, which will drive the two connecting blocks 7 to move away from the motor 12. The movement of the two connecting blocks 7 will drive the two adjusting arms 6 to move. The movement of the two adjusting arms 6 will pull the two pairs of rotating lifting arms 2 to rotate synchronously. The rotation of the two pairs of rotating lifting arms 2 will synchronously drive the two U-shaped support blocks 3 to move downward in an arc trajectory.

[0019] Then, the spool 5 with the roll material is moved between the two U-shaped support blocks 3, and the two U-shaped support blocks 3 are positioned below both ends of the spool 5; then the motor 12 is started in reverse, so that the two U-shaped support blocks 3 support the spool 5 and the roll material and move upward in an arc-shaped trajectory.

[0020] One end of each roller 4 on the two U-shaped support blocks 3 is fixedly mounted with a gear A13. Vertical plates 14 are fixedly mounted on the top of both ends of the U-shaped base 1. Gears B15 are rotatably mounted on the upper part of the opposite side of the two vertical plates 14. The two gears B15 are respectively meshed with the two gears A13. Sprockets A16 are fixedly mounted at the shaft center of the two gears B15. A dual-output shaft motor 17 is installed inside the U-shaped base 1. Both ends of the dual-output shaft motor 17 extend to the outside of both ends of the U-shaped base 1 and are fixedly mounted with sprockets B18. Chains 19 are installed between adjacent sprockets A16 and sprockets B18, so as to effectively adjust the rotation of the roll 5 and the roll material on it, so that the roll 5 drives the roll material to rotate and feed.

[0021] When the two U-shaped support blocks 3 lift and move the roll 5 and the roll material along an arc-shaped trajectory, the two U-shaped support blocks 3 will also drive the two gears A13 and B15 to mesh and connect. Then, the dual-output shaft motor 17 is started to make the two sprockets B18 rotate. The rotation of the two sprockets B18 will drive the two sprockets A16 to rotate through the two chains 19. The rotation of the two sprockets A16 will drive the two gears B15 to rotate. The rotation of the two gears B15 will drive the two gears A13 to rotate, thereby causing the two gears A13 to drive the two rollers 4 connected to them to rotate. At the same time, the other two rotatable rollers 4 will rotate the roll 5, so that the roll 5 will drive the roll material to perform unwinding and conveying operations, avoiding the roll material from being pulled and broken, thus preventing loss.

[0022] This feeding device has a lifting and feeding structure and a transmission feeding structure. The lifting and feeding structure can lift and install larger and heavier roll substrates, effectively ensuring the convenience and safety of roll substrate installation. The transmission feeding structure can drive the roll substrate to rotate synchronously and unwind during the feeding process, thereby effectively improving the stability of feeding.

[0023] Furthermore, this feeding device has a simple structural design, is easy to use, and has stable and reliable adjustment. Its practicality can meet the feeding requirements of foam tape hot pressing molding.
