Description

Technical Field

[0001] This utility model relates to the field of cotton packaging film technology, specifically a feeding mechanism for cotton packaging film production. Background Technology

[0002] Cotton packaging film, as the name suggests, is a plastic film specifically designed for packaging cotton. It is not simply a plastic sheet, but a specialized packaging material with specific properties to meet specific industrial needs. Made through a blow molding process, it is a high-strength, high-toughness, waterproof, and breathable plastic film, primarily used for packing cotton after harvesting to facilitate transportation and storage. Cotton packaging film is generally transported in rolls after production. With the continuous production of cotton packaging film rolls, various feeding devices have emerged, such as a feeding mechanism for cotton packaging film production.

[0003] A search revealed a cotton packaging film production feeding mechanism in Chinese utility model patent CN202321400519.X, relating to the field of cotton packaging film processing and production. The mechanism includes a conveying component and a feeding base. A polygonal load-bearing component is connected to the output shaft of an adjacent load-bearing motor. A limiting groove is formed on the circumference of the polygonal load-bearing component. A dual-axis cylinder is bolted to the center of the limiting groove. A feeding device is located on the top of the dual-axis cylinder. The bottom end of the feeding base plate slides into the limiting groove. A guide motor is located on the top surface of the feeding base. A connecting bracket is located at the end of the output shaft of the guide motor. A guide roller shaft engages between adjacent connecting brackets. The cotton packaging film is wound up by the rotation of the guide motor and the guide roller shaft after engagement. The dual-axis cylinder... The extension of the moving end drives the feeding plate, the guide motor, and the connecting bracket to move and separate along both sides of the guide roller shaft, realizing the rapid detachment of the guide roller shaft. During feeding, the cotton packaging film is subjected to uniform force, and the surface will not be damaged. It has high stability and surface protection. Although this device can realize the rapid detachment of the guide roller shaft and the simultaneous operation of multiple cotton packaging film rolls, the packaging film rolls at the top of the device will obviously fall from a height after production. Randomly falling from the front and back is more likely to cause damage. In addition, each packaging roll requires a motor, and the opening and closing of the feeding plate requires a cylinder, which is costly. Therefore, a feeding mechanism for cotton packaging film production is proposed that can be rolled vertically, which is less likely to damage the packaging film and is easy to remove. The belt pulley drives the dual shafts, saving costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a feeding mechanism for cotton packaging film production. It features vertical winding, which minimizes damage to the packaging film and facilitates easy removal. The belt pulley drives two shafts, saving costs. It solves the problems that after production, the packaging film rolls at the top of the device will obviously fall from a height, and random falling from the front and back is more likely to cause damage. Furthermore, each packaging roll requires a motor, and the opening and closing of the feeding plate requires a cylinder, resulting in high costs.

[0005] To achieve the above-mentioned goals of vertical winding, easy removal of packaging film, dual shaft drive by pulley, and cost saving, this utility model provides the following technical solution: a feeding mechanism for cotton packaging film production, including a working box, a controller fixedly installed on the front of the working box, and a feeding mechanism provided inside the working box; The discharge mechanism includes a servo motor, a rotating rod, a belt assembly, a transmission rod, a rotating seat, a movable cylinder, an electric telescopic rod, and a pressure plate. The servo motor is fixedly installed inside the work box. A rotating rod is provided at the output end of the servo motor. A belt assembly is provided outside the rotating rod. A transmission rod is provided outside the belt assembly. A rotating seat is provided at the bottom of the transmission rod. Movable cylinders are fixedly installed outside both the transmission rod and the rotating rod. An electric telescopic rod is fixedly installed on the top of the work box. A pressure plate is fixedly installed on the top of the electric telescopic rod.

[0006] Furthermore, the working box is equipped with two bearings inside, and the rotating rod and the transmission rod are movably connected to the working box through the two bearings respectively.

[0007] Furthermore, both movable cylinders have a frosted texture on their exterior, and both movable cylinders have a slot on their exterior that is compatible with the packaging film roll.

[0008] Furthermore, a fixing ring is fixedly installed on the outside of each of the two movable cylinders, and the upper surface of the two fixing rings is polished.

[0009] Furthermore, the bottom of the pressure plate is provided with two pressure rings, which are respectively adapted to the rotating rod and the transmission rod, and the lower surfaces of the two pressure rings are polished.

[0010] Furthermore, the belt assembly includes a first pulley, a belt body, and a second pulley.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects: This feeding mechanism for cotton packaging film production, through the setting of an output mechanism, allows the packaging film core to be fitted onto two movable cylinders when roll production is required. The electric telescopic rod retracts, and the pressure ring cooperates with the fixed ring below, pressing the packaging film core from both top and bottom directions during the winding process to achieve bidirectional axial limitation. Then, the servo motor drives the two movable cylinders to rotate synchronously clockwise via a belt assembly, thereby winding the packaging film. When it is necessary to remove it, the electric telescopic rod extends, which can easily and quickly remove the packaging film roll outside the movable cylinders. This output mechanism can wind vertically, which is less likely to damage the packaging film and facilitates removal. The belt pulley drives the dual shafts, saving costs.

Detailed Implementation

[0014] 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.

[0015] Please see Figure 1-4 The material feeding mechanism for cotton packaging film production in this embodiment includes a working box 1, a controller 2 fixedly installed on the front of the working box 1, and a material discharging mechanism 3 provided inside the working box 1. The discharge mechanism 3 includes a servo motor 301, a rotating rod 302, a belt assembly 303, a transmission rod 304, a rotating seat 305, a movable cylinder 306, an electric telescopic rod 307, and a pressure plate 308. The servo motor 301 is fixedly installed inside the work box 1. The output end of the servo motor 301 is provided with a rotating rod 302. The belt assembly 303 is provided outside the rotating rod 302. The transmission rod 304 is provided outside the belt assembly 303. The rotating seat 305 is provided at the bottom of the transmission rod 304. The movable cylinder 306 is fixedly installed outside both the transmission rod 304 and the rotating rod 302. The electric telescopic rod 307 is fixedly installed on the top of the work box 1. The pressure plate 308 is fixedly installed on the top of the electric telescopic rod 307.

[0016] In the implementation of the case, the working box 1 is equipped with two bearings 4. The rotating rod 302 and the transmission rod 304 are movably connected to the working box 1 through the two bearings 4 respectively. The bearings 4 are standard mechanical parts, and their core function is to reduce friction and support the rotating shaft. By setting the bearings 4, rotation can be ensured. The rotating rod 302 and the transmission rod 304 rotate at high speed and smoothly in the working box 1 with minimal frictional resistance. This is crucial for ensuring uniform winding speed and neat film rolls.

[0017] In the implementation of the case, both movable cylinders 306 have frosted texture 5 on their exteriors, and both movable cylinders 306 have slots on their exteriors that are compatible with the packaging film roll. The beginning of the packaging film needs to be fixed on the movable cylinder 306. The frosted texture 5 greatly increases the friction on the surface of the movable cylinder 306, and the slots provide a clear installation position that matches the inner diameter of the film roll core.

[0018] In the implementation of the case, fixing rings 6 are fixedly installed on the outside of both movable cylinders 306. The upper surfaces of the two fixing rings 6 are polished. The core function of the fixing rings 6 is to prevent the packaging film roll sleeved on the movable cylinders 306 from moving downward along the axis during the winding process.

[0019] In the implementation of the case, the bottom of the pressure plate 308 is provided with two pressure rings 7. The two pressure rings 7 are adapted to the rotating rod 302 and the transmission rod 304 respectively. The lower surfaces of the two pressure rings 7 are polished. The function of the pressure rings 7 is to press the packaging film roll (or core) from above during the winding process, and cooperate with the fixing ring 6 below to achieve bidirectional axial limiting.

[0020] In the implementation of the case, the belt assembly 303 includes a first pulley 8, a belt body 9, and a second pulley 10. The key structure that achieves the core advantage of "cost saving" in this patent is that, through the combination of the first pulley 8 (mounted on the output shaft of the servo motor 301), the second pulley 10 (mounted on the transmission rod 304), and the belt body 9, the power of one servo motor 301 is simultaneously transmitted to the rotating rod 302 and the transmission rod 304, thereby driving the two movable cylinders 306 to rotate synchronously. Compared with configuring a separate motor and driver for each workstation (such as the device mentioned in the background art) or using a gearbox or other transmission method, the belt drive structure is simple, has low manufacturing and maintenance costs, low operating noise, and has a certain overload protection capability.

[0021] In the implementation of this case, the controller 2 is electrically connected to all electronic components in this patent via wires, thereby controlling all electronic components in this patent by operating the controller 2.

[0022] When implementing this procedure, please follow these steps: 1) When the packaging film needs to be produced in rolls, first put the packaging film cores onto the two movable cylinders 306 respectively; 2) Then the electric telescopic rod 307 retracts, and the servo motor 301 drives the two movable cylinders 306 to rotate synchronously clockwise through the belt assembly 303; 3) Rewind the packaging film; 4) When it is finally time to remove the contents, the electric telescopic rod 307 extends, which makes it easy to quickly remove the packaging film roll outside the movable tube 306.

[0023] In summary, the feeding mechanism for cotton packaging film production, by setting up the discharge mechanism 3, allows the packaging film core to be respectively fitted onto two movable cylinders 306 when the packaging film needs to be rolled into rolls. The electric telescopic rod 307 retracts, and the pressure ring 7 cooperates with the fixed ring 6 below to press the packaging film core from both above and below during the winding process, achieving bidirectional axial limitation. Then, the servo motor 301 drives the two movable cylinders 306 to rotate synchronously clockwise through the belt assembly 303, thereby winding the packaging film. When it is necessary to remove it, the electric telescopic rod 307 extends, which can easily and quickly remove the packaging film roll outside the movable cylinders 306. This discharge mechanism 3 can wind vertically, which is less likely to damage the packaging film and facilitates removal. The belt pulley drives the dual shafts, saving costs.
