Description

Technical Field

[0001] This utility model relates to the field of biodegradable bag production technology, specifically to a biodegradable bag edge-locking device. Background Technology

[0002] Biodegradable bags are bags made of biodegradable materials that can be decomposed by microorganisms in the natural environment and eventually transformed into harmless substances, thereby reducing environmental pollution. In the production process of biodegradable bags, the biodegradable material needs to overflow from the blown film head and be cooled upwards to form a cylindrical structure. After passing through the extrusion rollers and herringbone clamps, it is conveyed. Then, the biodegradable bag needs to be divided into smaller biodegradable bags according to size. After the edge sealing process and the perforation process, the biodegradable bag is rolled up. When sealing the edge of the biodegradable bag, the movement of the biodegradable bag needs to be stopped.

[0003] According to Chinese Patent Publication No. CN219276837U, "A Sewing Device for Biodegradable Bags," the device mainly combines a frame, a pressing roller group, a forward and reverse motor, a fixed sewing strip, a sealing sensor, a lower heating mold, a movable sewing strip, an upper heating mold, an electric lifting arm, heat-conducting fins, and a cooling fan. After experimental optimization, the sewing device can press, position, and transport biodegradable bags, effectively preventing misalignment at the bag opening. It can also cool the sewn biodegradable bags through contact, resulting in high cooling efficiency and improving the sewing quality. However, during this process, the transport needs to be stopped when sewing the biodegradable bags and opening the dotted lines, which would affect the subsequent winding of the biodegradable bags.

[0004] Therefore, a biodegradable bag edge-locking device is proposed to solve the problem that the conveying needs to be stopped when locking the biodegradable bag edge and opening the dotted line hole, which will affect the subsequent winding of the biodegradable bag. Utility Model Content

[0005] The technical problem to be solved by this utility model is that during the process of locking the edge of the biodegradable bag and opening the dotted hole, the conveying needs to be stopped, which will affect the subsequent winding of the biodegradable bag. Therefore, a biodegradable bag locking device is proposed.

[0006] The technical solution adopted by this utility model to solve the technical problem is as follows: a biodegradable bag edge-locking device, including a support plate, on which conveying rollers are rotatably connected to both sides of the support plate that are far apart from each other, a connecting plate is rotatably connected to the upper side of the support plate through a rotating shaft, an electric push rod is fixedly connected to the bottom end of the connecting plate, a moving frame is fixedly connected to the output end of the electric push rod, two drive motors are fixedly connected to one side of the moving frame, a bidirectional screw is fixedly connected to the output end of the drive motor, a moving plate is threadedly connected to both sides of the bidirectional screw that are far apart from each other, a heat pipe is uniformly fixedly connected to the bottom end of the moving plate, a heat-conducting plate is fixedly connected to the bottom end of the heat pipe, a sealing plate is fixedly connected to the bottom end of one of the heat-conducting plates, and a dotted line plate is fixedly connected to the bottom end of the other heat-conducting plate, the heat pipe is connected to an external power supply through a wire, the external power supply is fixedly connected to the upper end of the moving frame, a pad is fixedly connected to the bottom side of the support plate, the pad is connected to the external power supply through a wire, a slot is opened on the pad, and a contact block is fixedly connected in the slot.

[0007] As a preferred technical solution of this utility model, both ends of the heat-conducting sheet are fixedly connected to vertical plates, and a positioning rod is inserted into the vertical plate and the positioning rod is threadedly connected to a moving plate. By setting the positioning rod and the moving plate, the disassembly and replacement effect can be provided to adapt to biodegradable bags of different widths.

[0008] As a preferred technical solution of this utility model, the upper sides of the movable plate are rotatably embedded with support balls, and the support balls are in contact with the inner side of the movable frame. By setting the support balls, the friction of the movable plate movement is reduced.

[0009] As a preferred technical solution of this utility model, a limiting strip is fixedly connected to the support plate. The limiting strip is in contact with the connecting plate. By setting the limiting strip, the connecting plate can be easily rotated to replace the biodegradable bag.

[0010] As a preferred technical solution of this utility model, a handle is fixedly connected to one side of the upper end of the connecting plate. The handle is close to the limiting strip, and the handle makes it easy to pull.

[0011] This utility model has the following advantages: By setting a rotatable connecting plate on the fixed plate and replacing the size of the sealing plate and the dotted line plate by disassembling the positioning rod, it can meet the needs of sealing and opening biodegradable bags of different widths and improve the efficiency of installation and disassembly. Then, by controlling the rotation of the bidirectional screw through the drive motor, the two moving plates can move relative to each other, which can control the distance between the dotted line plate and the sealing plate. Thus, two processes can be solved with one stop, which can reduce the downtime required in the production of biodegradable bags and improve process efficiency. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3 The biodegradable bag sealing device shown includes a support plate 1. Conveying rollers 2 are rotatably connected to both sides of the support plate 1, which are far apart from each other. A connecting plate 3 is rotatably connected to the upper side of the support plate 1 via a rotating shaft. An electric push rod 4 is fixedly connected to the bottom end of the connecting plate 3. A shift frame 5 is fixedly connected to the output end of the electric push rod 4. The electric push rod 4 can drive the shift frame 5 to move up and down, so that the biodegradable bag is in contact with the bottom side of the shift frame 5 and the upper side of the pad 12. Two drive motors are fixedly connected to one side of the shift frame 5. A bidirectional screw 6 is fixedly connected to the output end of the drive motor. Moving plates 7 are threadedly connected to both sides of the bidirectional screw 6, which are far apart from each other. The drive motors drive the bidirectional screw 6 to rotate, which allows the two moving plates 7 to move relative to each other or move away from each other, thereby controlling the distance between the dotted holes on the biodegradable bag and the sealing edge. The bottom end of the moving plates 7 is uniformly... A heat pipe 8 is fixedly connected, and a heat-conducting plate 9 is fixedly connected to the bottom end of the heat pipe 8. One heat-conducting plate 9 is fixedly connected to the bottom end of the edge sealing plate 10, and the other heat-conducting plate 9 is fixedly connected to the bottom end of the dotted line plate 15. The bottom side of the dotted line plate 15 has protrusions evenly fixedly connected. The heat pipe 8 is connected to an external power supply 11 through a wire. The external power supply 11 is fixedly connected to the upper end of the moving frame 5. A pad 12 is fixedly connected to the bottom side of the support plate 1. The pad 12 is connected to the external power supply 11 through a wire. A slot 13 is opened on the pad 12. A contact block 14 is fixedly connected in the slot 13. The external power supply 11 supplies power to the heat pipe 8 through a wire and conducts it to the heat-conducting plate 9, thereby sealing the edge with the edge sealing plate 10. At the same time, the edge sealing plate 10 presses one side of the biodegradable bag into the slot 13, so that the biodegradable bag contacts the contact block 14, providing a double-sided sealing effect.

[0018] The movable plate 7 is threaded with a positioning rod 16, which is inserted into a vertical plate 17. The vertical plate 17 is fixedly connected to both ends of the heat-conducting sheet 9. By disassembling the positioning rod 16, the appropriate size of the sealing plate 10 and the dotted line plate 15 can be selected and installed according to the width of the biodegradable bag.

[0019] The inner side of the moving frame 5 contacts the support ball 18, and the support ball 18 is rotatably embedded on both sides of the upper end of the moving plate 7. By setting the support ball 18, the friction experienced by the moving plate 7 during movement is reduced, while providing a support effect.

[0020] The connecting plate 3 is in contact with the limiting strip 19, which is fixedly connected to the support plate 1. The limiting strip 19 provides support for the connecting plate 3.

[0021] The limiting strip 19 is located near the handle, which is fixedly connected to one side of the upper end of the connecting plate 3. The handle facilitates the pulling of the connecting plate 3.

[0022] Working principle: Based on the width of the biodegradable bag, the connecting plate 3 is flipped and the positioning rod 16 is removed, thereby detaching the vertical plate 17. At this time, a sealing plate 10 and a dotted line plate 15 of appropriate length are selected, and then fixedly connected to the bottom side of the heat pipe 8 using the positioning rod 16. Then, the drive motor is controlled to rotate the bidirectional screw 6, and the two moving plates 7 are brought closer to a suitable distance. Then, the sealing plate 10 and the dotted line plate 15 correspond to the pad 12. At this time, the biodegradable bag moves from one side of the conveying roller 2 to the upper side of the pad 12. When it reaches a certain distance, the electric push rod 4 drives the moving frame 5 to move down and contact the biodegradable bag on the pad 12. The external power supply 11 supplies power to the heat pipe 8 through the wire, so that the heat pipe 8 and the contact block 14 generate heat. Then, the electric push rod 4 drives the sealing plate 10 and the dotted line plate 15 to contact the biodegradable bag, thereby forming the sealing edge and the dotted line hole, thus solving the time of the two processes.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
