Description
Technical Field
[0001] This utility model relates to the field of packaging bag winding technology, specifically a packaging bag winding device. Background Technology
[0002] Plastic packaging bags are packaging bags made of plastic as raw material, used in the production and daily life of various products. They are widely used in daily life and industrial production. However, this convenience brings long-term harm. Most commonly used plastic packaging bags are made of polyethylene film, which is non-toxic and can therefore be used to hold food. Another type of film is made of polyvinyl chloride (PVC). PVC itself is also non-toxic, but the additives added to the film depending on its intended use are often substances that are harmful to the human body and have a certain degree of toxicity. Therefore, this type of film and the plastic bags made from it are not suitable for holding food.
[0003] The existing Chinese utility model patent with publication number CN221700614U discloses a packaging bag winding device, including a base, a support frame fixedly mounted on the upper end of the base, an arc-shaped groove on the support frame, a baffle at the upper end of the arc-shaped groove, and the baffle being fixedly connected to the support frame; a winding drum is provided in the arc-shaped groove, and connecting parts are provided at both ends of the winding drum, with a lifting rod fixedly connected to the lower end of the connecting parts; a fixed rod and a lifting device are provided on one side of the support frame, and the lifting device is connected to the fixed rod; a sorting cylinder is provided on one side of the winding drum, and a guide rod is provided on one side of the sorting cylinder, and the guide rod is fixedly connected to the support frame through a fixing block; this utility model is convenient to use, has a simple structure, and allows for adjustment of the winding size by adjusting the height of the winding drum during winding, thus providing high flexibility.
[0004] In the aforementioned packaging bag winding device, although the designed winding drum can slide up and down, allowing the device to adjust according to different winding thicknesses and solving the problems of low efficiency and long time consumption when changing the collection drum in traditional plastic packaging bag winding devices—problems that have seriously affected the subsequent packaging and transportation efficiency of plastic bags—the device still suffers from some instability in practical applications. In current mechanical designs, the connection of the winding drum via connectors still presents some challenges in stability. Furthermore, disassembling the winding drum is quite cumbersome and complex. These issues not only reduce the ease of use of the equipment but also negatively impact overall work efficiency to some extent. Utility Model Content
[0005] The purpose of this invention is to overcome the problem of inconvenient operation in the existing technology and to provide a packaging bag winding device.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A packaging bag winding device, comprising:
[0008] A winding box has a support base fixedly installed on one side. The support base is U-shaped. Two rotating seats are fixedly installed on the top two sides of the support base. An air shaft is rotatably connected to the top of the rotating seats. A winding roller is clamped and connected to the outer side of the middle of the air shaft. A driven gear is fixedly installed on one side of the air shaft. A support plate is fixedly installed on one side of the support base. A drive motor is fixedly installed on the top of the support plate. A drive gear is fixedly installed on one side of the drive motor. Two electric push columns are fixedly installed on the top two sides of the support base. A connecting plate is fixedly installed in the middle of the electric push columns. A clamping wheel is rotatably connected to the bottom side of the connecting plate.
[0009] In a preferred embodiment, four guide rollers are rotatably connected to the inner sides of the winding box, and two fixing grooves are fixedly installed on the inner sides of the winding box. The fixing grooves are structures used to fix the lifting groove.
[0010] In a preferred embodiment, a lifting groove is fixedly installed inside the fixing groove, and a support spring is fixedly installed at the top inside the lifting groove. The support spring is a structure used to adjust the tension.
[0011] In a preferred embodiment, a lifting block is fixedly installed at the bottom of the support spring, and a support roller is rotatably connected to one side of the lifting block. The support roller is a structure used for support.
[0012] In a preferred embodiment, two electric actuators are fixedly installed on both sides of the inside of the winding box, and a support rod is fixedly installed on one side of each electric actuator. The support rod is a structure used for connection.
[0013] In a preferred embodiment, two baffles are fixedly installed in the middle of the support rod, and a limit block is fixedly installed on one side of the support rod. The limit block is a structure used for limiting movement.
[0014] In a preferred embodiment, a connecting roller is rotatably connected to the middle outer side of the support rod, and a silicone block is fixedly installed on the outer side of the connecting roller. The silicone block is a structure for anti-slip purposes.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. This packaging bag winding device clamps the winding roller by the operation of the air shaft. The rotating seat supports both sides of the air shaft. The operation of the electric push column drives the connecting plate to move downward, so that the clamping wheels clamp the top of both sides of the air shaft, thereby clamping and fixing the air shaft. Through the meshing of the drive gear and the driven gear, when the drive motor is running, it drives the winding roller on the outside of the air shaft to rotate and wind up. When it is necessary to disassemble the winding roller, the operation of the electric push column releases the clamp on the air shaft, which improves the convenience of the packaging bag winding device.
[0017] 2. This packaging bag winding device limits the connecting roller by using a baffle on the outside of the support rod, allowing the connecting roller to rotate outside the support rod. A silicone block on the outside of the connecting roller adheres to the packaging bag, providing an anti-slip effect. The operation of the electric push rod moves the support rod inside the winding box, adjusting the position of the connecting roller to calibrate the packaging bag. This prevents the packaging bag from shifting during winding, improving the practicality of the packaging bag winding device. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Combined with appendix Figure 1-4 In this embodiment, a packaging bag winding device includes: a winding box 1, four guide rollers 11 are rotatably connected to the inside two sides of the winding box 1, two fixing grooves 12 are fixedly installed on the inside two sides of the winding box 1, a lifting groove 13 is fixedly installed inside the fixing groove 12, a support spring 14 is fixedly installed at the top inside the lifting groove 13, a lifting block 15 is fixedly installed at the bottom of the support spring 14, and a support roller 16 is rotatably connected to one side of the lifting block 15.
[0025] Specifically, the packaging bag is guided by the guide rollers 11 on both sides inside the winding box 1, the lifting groove 13 is supported by the fixed groove 12, and the lifting block 15 is moved up and down inside the lifting groove 13 by the contraction of the support spring 14 inside the lifting groove 13, thereby adjusting the position of the support roller 16 so as to adjust the tension of the packaging bag during winding.
[0026] Two electric push rods 2 are fixedly installed on both sides inside the winding box 1. A support rod 21 is fixedly installed on one side of the electric push rod 2. Two baffles 22 are fixedly installed in the middle of the support rod 21. A limit block 23 is fixedly installed on one side of the support rod 21. A connecting roller 24 is rotatably connected to the outer side of the middle of the support rod 21. A silicone block 25 is fixedly installed on the outer side of the connecting roller 24.
[0027] Specifically, the operation of the electric push rod 2 pushes the support rod 21 to slide inside the winding box 1. The support rod 21 is limited by the limiting block 23 on one side, which drives the connecting roller 24 to move. The movement of the connecting roller 24 drives the outer packaging bag to move, thereby adjusting the position of the packaging bag and avoiding the problem of displacement. The silicone block 25 plays a role in preventing slippage.
[0028] A support base 3 is fixedly installed on one side of the winding box 1. The support base 3 is in the shape of a "U". Two rotating seats 31 are fixedly installed on the top two sides of the support base 3. An air shaft 32 is rotatably connected to the top of the rotating seat 31. A winding roller 33 is clamped and connected to the middle outer side of the air shaft 32. A driven gear 34 is fixedly installed on one side of the air shaft 32. A support plate 35 is fixedly installed on one side of the support base 3. A drive motor 36 is fixedly installed on the top of the support plate 35. A drive gear 37 is fixedly installed on one side of the drive motor 36. Two electric push columns 38 are fixedly installed on the top two sides of the support base 3. A connecting plate 39 is fixedly installed in the middle of the electric push column 38. A clamping wheel 310 is rotatably connected to the bottom side of the connecting plate 39.
[0029] Specifically, the drive motor 36 is supported by the support plate 35. The operation of the drive motor 36 drives the drive gear 37 to rotate, which in turn drives the driven gear 34 to rotate, thereby driving the outer winding roller 33 of the air shaft 32 to rotate, thus winding up the packaging bag. The retraction of the electric push column 38 drives the connecting plate 39 to retract, so as to facilitate the disassembly of the air shaft 32.
[0030] Working principle: First, the packaging bag is guided by four guide rollers 11 on both sides inside the winding box 1. The lifting groove 13 is supported by two fixing grooves 12 on both sides inside the winding box 1. The packaging bag passes through the bottom of the support roller 16 and is supported by the support roller 16. During the winding process, when the packaging bag is too tight, the support spring 14 contracts, causing the lifting block 15 to move upward inside the lifting groove 13, thereby adjusting the tension of the packaging bag during the winding process and avoiding damage to the packaging bag due to excessive tightness. The connecting roller 24 is limited by the baffles 22 on both sides of the support rod 21. The operation of the electric push rod 2 pushes the support rod 21 to move inside the winding box 1, thereby adjusting the position of the connecting roller 24. The silicone block 25 adheres to the packaging bag to provide an anti-slip effect and facilitates adjustment of the bag's offset, improving the convenience of the packaging bag winding device. The operation of the drive motor 36 on the top of the support plate 35 drives the drive gear 37 to rotate. Through the meshing of the drive gear 37 and the driven gear 34 on one side of the air shaft 32, the air shaft 32 and the winding roller 33 on its outer side are driven to rotate, thereby winding the packaging bag. When the winding roller 33 needs to be replaced, the operation of the electric push column 38 drives the connecting plate 39 and the clamping wheel 310 to move upward, thereby releasing the clamp on the air shaft 32, making it easy to remove the air shaft 32 and replace the winding roller 33, thus improving the convenience of replacing the winding roller 33 in the packaging bag winding device.
[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
