Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic bag processing technology, and specifically to a forming device for plastic bag processing. Background Technology
[0002] Plastic bags are bags made primarily of plastic and are widely used in daily life, often for storing other items. The main components of plastic bags include polyethylene, polypropylene, polyester, and nylon, which give plastic bags advantages such as low cost, light weight, large capacity, and ease of storage.
[0003] However, when using existing plastic bag forming equipment, the rollers usually wind up the formed plastic bags. However, when too many plastic bags are wound up outside the rollers, the equipment needs to be stopped, and then the workers need to manually disassemble the rollers and install new rollers to wind up the plastic bags. The operation is cumbersome and has a certain impact on the processing efficiency of plastic bags. Therefore, a new forming device for plastic bag processing is proposed. Utility Model Content
[0004] The main objective of this invention is to provide a forming device for plastic bag processing. This invention solves the problem of low processing efficiency of existing plastic bag forming devices by setting up a servo motor A, drive plate A, drive plate B, servo motor B, roller A, roller B, connecting frame, and cutter.
[0005] The technical solution adopted by this utility model to solve its technical problem is a forming device for processing plastic bags, including a machine body. A conveying roller for conveying plastic bags is rotatably connected to the inside of the machine body. A servo motor B, providing power, is bolted to the outside of the machine body, and a drive plate B is keyed to the power output end of the servo motor B. A winding roller A and a winding roller B for winding plastic bags are symmetrically rotatably connected to the inside of the drive plate B. A drive plate A connected to the winding roller A and the winding roller B is connected inside the machine body. The inner sides of both drive plates A and B are symmetrical. A fixing assembly is provided to fix rollers A and B. The fixing assembly includes a fixing sleeve, an arc plate, and a threaded sleeve. A servo motor A, which provides power, is bolted inside the drive plate A. The power output end of the servo motor A is keyed to the fixing sleeve that drives the roller A to rotate. A connecting frame is symmetrically fixed to one side of the machine body with screws. A cutter for cutting plastic bags is fixed to the inside of the connecting frame with screws. A fan that generates suction inside the roller A is fixed to the inside of the roller A with screws. A through hole is opened on the surface of the roller A to suck up the plastic bag.
[0006] By adopting the above technical solution, when the conveying roller in the machine head conveys the formed plastic bag, the fan in the roller A is controlled by an external controller, causing suction to be generated inside the roller A. Then, the roller A adsorbs the plastic bag through several through holes on its surface. Then, the servo motor A in the drive plate A is controlled by an external controller to drive the roller A in the fixed sleeve to rotate, so that the plastic bag is rolled up outside the roller A. After the roller A is finished rolling up outside, the servo motor B on the machine head is controlled by an external controller to convert the received electrical energy into mechanical energy. Then, the rollers A and B in the drive plate A and drive plate B rotate. Then, the plastic bag on the roller A contacts the cutter in the connecting frame, and the cutter cuts the plastic bag. At the same time, the internal structure of the roller B is the same as that of the roller A. The roller B adsorbs the plastic bag. Then, another set of servo motors A in the drive plate A drives the roller B to rotate, so that the roller B continues to roll up the plastic bag, thereby improving the processing efficiency of the plastic bag.
[0007] Bearings are provided at the connection between the drive plate A and the machine body, and at the connection between the fixing sleeves at the ends of rollers A and B and the drive plate A.
[0008] Specifically, a bracket is bolted to the top of the machine body, and an electric telescopic rod that provides power is fixed to the inside of the bracket with screws. A drive frame is fixed to the power output end of the electric telescopic rod with screws, and a pressure roller that flattens the plastic bags on the conveyor roller is rotatably connected to the inside of the drive frame.
[0009] By adopting the above technical solution, when the conveying roller inside the machine conveys the plastic bag, the electric telescopic rod inside the bracket is driven by the external controller to move the drive frame, so that the pressure roller inside the drive frame comes into contact with the plastic bag outside the conveying roller, thereby making it easier to flatten the conveyed plastic bag and avoid wrinkles in the formed plastic bag.
[0010] Specifically, the fixed sleeve has an integrally formed arc plate that contacts the roller A.
[0011] By adopting the above technical solution, when the roller A is placed inside the fixed sleeve, the arc plate outside the fixed sleeve contacts the surface of the roller A, thereby facilitating the fixing of the roller A.
[0012] Specifically, the fixed sleeve has an external threaded connection that tightly connects the arc plate and the roller A.
[0013] By adopting the above technical solution, the fixed sleeve is externally threaded with a threaded sleeve. As the threaded sleeve moves, the arc plate contacts and separates from the roller A, thereby facilitating the fixing and disassembly of the roller A.
[0014] Specifically, the input terminals of the electric telescopic rod, servo motor A, and servo motor B are all electrically connected to the power supply terminal of an external power source.
[0015] By adopting the above technical solution and connecting to an external power source, the electrical equipment can operate normally.
[0016] The beneficial effects of this utility model are:
[0017] (1) The forming device for processing plastic bags described in this utility model, when the conveying roller in the machine head conveys the formed plastic bag, the fan in the roller A is controlled by an external controller, so that the roller A generates suction inside. Then the roller A adsorbs the plastic bag through several through holes on its surface. Then the servo motor A in the drive plate A is controlled by an external controller to drive the roller A in the fixed sleeve to rotate, so that the plastic bag is rolled up outside the roller A. After the roller A is rolled up, the servo motor B on the machine head is controlled by an external controller to convert the received electrical energy into mechanical energy. Then the roller A and roller B in the drive plate A and drive plate B rotate. Then the plastic bag on the roller A contacts the cutter in the connecting frame. The cutter cuts the plastic bag. At the same time, the internal structure of the roller B is the same as the internal structure of the roller A. The roller B adsorbs the plastic bag. Then another set of servo motors A in the drive plate A drives the roller B to rotate, so that the roller B continues to roll up the plastic bag, thereby improving the processing efficiency of the plastic bag.
[0018] (2) In the plastic bag forming device described in this utility model, when the conveying roller in the machine body conveys the plastic bag, the electric telescopic rod in the bracket is driven by the external controller to move the drive frame, so that the pressure roller in the drive frame contacts the plastic bag outside the conveying roller, thereby making it easier to flatten the conveyed plastic bag and avoid wrinkles in the formed plastic bag.

Detailed Implementation
[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] To improve the processing efficiency of plastic bags, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the forming device for processing plastic bags according to this utility model includes a machine body 1. A conveying roller 6 for conveying plastic bags is rotatably connected to the inner side of the machine body 1. A servo motor B17 for providing power is bolted to the outer side of the machine body 1, and a drive plate B20 is keyed to the power output end of the servo motor B17. A winding roller A13 and a winding roller B15 for winding plastic bags are symmetrically rotatably connected to the inner side of the drive plate B20. A drive plate A12 connected to the winding roller A13 and the winding roller B15 is connected inside the machine body 1. The inner sides of both the drive plate A12 and the drive plate B20 are symmetrically arranged with rollers A13 and B15 for winding plastic bags. The fixing assembly 11 for fixing the roller B15 includes a fixing sleeve 10, an arc plate 19 and a threaded sleeve 9. The drive plate A12 is bolted to a servo motor A8 that provides power, and the power output end of the servo motor A8 is keyed to the fixing sleeve 10 that drives the roller A13 to rotate. A connecting frame 18 is symmetrically screwed to one side of the machine body 1, and a cutter 16 for cutting plastic bags is screwed to the inside of the connecting frame 18. A fan 7 that generates suction inside the roller A13 is screwed to the inside of the roller A13. The surface of the roller A13 has through holes 14 for sucking up plastic bags.
[0027] During operation, when the conveyor roller 6 inside the machine head conveys the formed plastic bag, the fan 7 inside the roller A13, under the action of an external controller, generates suction inside the roller A13. The roller A13 then attracts the plastic bag through several through holes 14 on its surface. Next, the servo motor A8 inside the drive plate A12, under the action of an external controller, drives the roller A13 inside the fixed sleeve 10 to rotate, causing the plastic bag to be wound up outside the roller A13. After the roller A13 has finished winding up, the servo motor B17 on the machine head, under the action of an external controller, will... The electrical energy is converted into mechanical energy, and then the rollers A13 and B15 in the drive plates A12 and B20 rotate. The plastic bag on the roller A13 then comes into contact with the cutter 16 in the connecting frame 18, and the cutter 16 cuts the plastic bag. At the same time, the internal structure of the roller B15 is the same as that of the roller A13, and the roller B15 adsorbs the plastic bag. Then, another set of servo motors A8 in the drive plate A12 drives the roller B15 to rotate, so that the roller B15 continues to wind up the plastic bag, thereby improving the processing efficiency of the plastic bag.
[0028] To avoid wrinkles in the formed plastic bags, for example, such as Figure 1 As shown, the present invention also includes a bracket 2 bolted to the top of the machine body 1, and an electric telescopic rod 3 for providing power is fixed to the inner side of the bracket 2 by screws. A drive frame 4 is fixed to the power output end of the electric telescopic rod 3 by screws, and a pressure roller 5 for flattening the plastic bags on the conveying roller 6 is rotatably connected to the inner side of the drive frame 4.
[0029] When in use, when the conveying roller 6 inside the machine body 1 conveys the plastic bag, the electric telescopic rod 3 inside the bracket 2 is driven by the external controller to move the drive frame 4, so that the pressure roller 5 inside the drive frame 4 comes into contact with the plastic bag outside the conveying roller 6, thereby making it easier to flatten the conveyed plastic bag and avoid wrinkles in the formed plastic bag.
[0030] To secure the roller A13, for example, such as Figure 4 As shown, the present invention also includes an arc plate 19 integrally formed on the outside of the fixed sleeve 10, which contacts the roller A13.
[0031] When in use, when the roller A13 is placed inside the fixing sleeve 10, the arc plate 19 outside the fixing sleeve 10 contacts the surface of the roller A13, thereby facilitating the fixing of the roller A13.
[0032] To facilitate the fixing and disassembly of the roller A13, for example, such as Figure 4 As shown, the present invention also includes a threaded sleeve 9 on the outside of the fixed sleeve 10, which tightly connects the arc plate 19 and the roller A13.
[0033] In use, the fixed sleeve 10 is externally threaded with a threaded sleeve 9. As the threaded sleeve 9 moves, the arc plate 19 contacts and separates from the roller A13, which facilitates the fixing and disassembly of the roller A13.
[0034] For electrical equipment to function properly, for example, such as Figure 1 , Figure 2 and Figure 3 As shown, this utility model also includes the fact that the input ends of the electric telescopic rod 3, the servo motor A8, and the servo motor B17 are all electrically connected to the power supply end of an external power source.
[0035] When in use, the electrical equipment works normally by connecting to an external power source.
[0036] In use, when the conveyor roller 6 inside the machine head conveys the formed plastic bag, the fan 7 inside the roller A13, under the action of an external controller, generates suction inside the roller A13. Then, the roller A13 attracts the plastic bag through several through holes 14 on its surface. Then, the servo motor A8 inside the drive plate A12, under the action of an external controller, drives the roller A13 inside the fixed sleeve 10 to rotate, so that the plastic bag is rolled up outside the roller A13. After the roller A13 finishes rolling up, the servo motor B17 on the machine head, under the action of an external controller... The received electrical energy is converted into mechanical energy, and then the rollers A13 and B15 in the drive plate A12 and drive plate B20 rotate. Then the plastic bag on the roller A13 comes into contact with the cutter 16 in the connecting frame 18, and the cutter 16 cuts the plastic bag. At the same time, the internal structure of the roller B15 is the same as that of the roller A13, and the roller B15 adsorbs the plastic bag. Then another set of servo motors A8 in the drive plate A12 drives the roller B15 to rotate, so that the roller B15 continues to wind up the plastic bag, thereby improving the processing efficiency of the plastic bag.
[0037] When the conveying roller 6 inside the machine body 1 conveys the plastic bag, the electric telescopic rod 3 inside the bracket 2 is driven by the external controller to move the drive frame 4, so that the pressure roller 5 inside the drive frame 4 comes into contact with the plastic bag outside the conveying roller 6, thereby making it easier to flatten the conveyed plastic bag and avoid wrinkles in the formed plastic bag.
[0038] When the roller A13 is placed inside the fixing sleeve 10, the arc plate 19 outside the fixing sleeve 10 contacts the surface of the roller A13, thereby facilitating the fixing of the roller A13.
[0039] The fixed sleeve 10 is externally threaded with a threaded sleeve 9. As the threaded sleeve 9 moves, the arc plate 19 contacts and separates from the roller A13, thereby facilitating the fixing and disassembly of the roller A13.
