Description

Technical Field

[0001] This utility model mainly relates to the technical field of PE film processing, specifically a winding device for PE film production. Background Technology

[0002] PE film winding equipment is a key piece of equipment in PE film production lines. It is mainly used to uniformly and tightly wind cast or blow-molded polyethylene films into rolls. The wound film rolls are easy to transport, store, and process for subsequent cutting, bag making, etc., and can maintain the mechanical, optical and barrier properties of the film. Existing PE film winding equipment usually uses conventional motor-driven winding, which is prone to problems such as deviation and wrinkles, and is not easy to discharge.

[0003] According to application number 202222408537.4, a winding device for PE film production includes a base, casters, and a pedal lock. The casters are fixedly connected to the lower surface of the base, and the pedal lock is fixedly connected between the base and the casters. A fixed seat is fixedly connected to one side of the upper surface of the base, and a second upright plate is fixedly connected to the other side of the upper surface of the base. A first upright plate is fixedly connected between the second upright plate and the fixed seat. A buffer pad is fixedly connected to the upper surface of the fixed seat, and a coaxial geared motor is fixedly connected to the buffer pad. A drive shaft is fixedly connected to the output end of the coaxial geared motor, and a disc-shaped buckle is connected to the other end of the drive shaft. Four sets of bolts are threaded onto the surface of the disc-shaped buckle.

[0004] The aforementioned document improves the structure, resulting in a winding device with low noise and high efficiency. It separates the winding drum from the device using the lever principle, making it convenient and quick to complete tasks such as loading and unloading the drum. However, it lacks a structure for stretching PE film and cannot prevent wrinkles from occurring during winding. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a winding device for PE film production to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A winding device for PE film production includes a power supply base, guide rails fixedly mounted on both sides of the top of the power supply base, two mounting plates fixedly mounted on both sides of the top of the guide rails, a heating wheel rotatably mounted at one end of the middle of the guide rails, two limiting wheels rotatably mounted on the middle of the guide rails at both ends of the heating wheel, a driving component rotatably mounted on one side of the other end of the middle of the guide rails, and a clamping component rotatably mounted on the other side of the other end of the middle of the guide rails. The driving component and the clamping component assist in rotating and clamping the winding wheel, and a detection component is slidably mounted on the middle of the two mounting plates.

[0008] One end of the heating wheel is fixedly connected to a wide gear located on the outside of the guide rail, and a first motor is fixedly installed on the outside of the other side of the guide rail. The actuator end of the first motor is connected to the central shaft of the wide gear.

[0009] One end of the limiting wheel is fixedly connected to a narrow gear located on the outside of the guide rail and meshing with the wide gear. Two limiting cylinders are sleeved on the outside of the limiting wheel. Multiple rows of first screw holes are opened on the outer wall of the limiting wheel, and multiple through second screw holes are opened on the side wall of the limiting cylinder.

[0010] The driving component includes a first convex disk rotatably mounted on the inner wall of the guide rail, and a second motor fixedly mounted on one side of the outer side of the guide rail, with the actuating end of the second motor fixedly connected to the central shaft of the first convex disk.

[0011] The clamping component includes multiple electric actuators fixedly mounted in a ring on the inner side of the guide rail. The actuator ends of the multiple electric actuators are fixedly connected to a ring mounting plate. A bearing is installed in the middle of the other side of the ring mounting plate, and a second convex plate is installed inside the bearing.

[0012] The surface of the take-up reel is rough, and the two ends of the take-up reel are provided with fitting grooves for fitting the first convex disk and the second convex disk. The bottom of the guide rail is fixedly provided with an inclined groove located at the bottom of the take-up reel.

[0013] The detection component includes two sliding rods arranged vertically and fixed at both ends to the middle of the two mounting plates. Multiple detection boxes are slidably installed on the outside of the sliding rods. A sliding plate is slidably installed inside the detection box. A pressure sensor is fixedly installed at the top inside the detection box. The bottom of the pressure sensor is connected to the top of the sliding plate by multiple high-precision springs. A driven wheel is rotatably installed at the bottom of the sliding plate.

[0014] In summary, this technical solution has the following main advantages:

[0015] This invention significantly improves the quality and production efficiency of film winding through optimized structural design. The device adopts a method of coordinated operation of heating wheels and limiting wheels. The film passes evenly through the heating area through gear transmission. Two adjustable-gap limiting cylinders effectively restrict the position of the film, which can not only ensure that the film is fully stretched and avoids wrinkles, but also adapt to the winding requirements of films of different widths. The setting of heating wheels further improves the shaping effect of the film, so that the wound film remains flat.

[0016] This device achieves automated control of the winding process through an intelligent detection system. The pressure sensor in the detection component monitors the change in film roll diameter in real time and feeds the data back to the PLC control system, which dynamically adjusts the speed of the winding motor to ensure a constant winding speed. This closed-loop control effectively avoids problems such as uneven film tension, wrinkles, or tears caused by increased roll diameter. At the same time, the clamping component is driven by an electric push rod, which can automatically release the roll after winding is completed, and facilitates convenient material discharge with the inclined chute, greatly improving the continuity of production and ease of operation.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Example

[0025] Please refer to the attached document carefully. Figure 1 , 2As shown in Figure 4, a winding device for PE film production includes a power supply base 10. Guide rails 11 are fixedly mounted on both sides of the top of the power supply base 10. Two mounting plates 12 are fixedly mounted on both sides of the top of the guide rails 11. A heating wheel 13 is rotatably mounted at one end of the middle of the guide rail 11. Two limiting wheels 14 rotatably mounted on the middle of the guide rail 11 are tightly attached to both ends of the heating wheel 13. A driving component 15 is rotatably mounted on one side of the other end of the guide rail 11. A clamping component 16 is rotatably mounted on the other side of the other end of the guide rail 11. The driving component 15 and the clamping component 16 assist in rotating and clamping a winding wheel 17. The two mounting plates 12... A detection component 18 is slidably mounted in the middle of plate 12; a wide gear 131 is fixedly connected to one end of heating wheel 13 on the outside of guide rail 11, and a first motor 132 is fixedly mounted on the other side of guide rail 11, with the execution end of the first motor 132 connected to the central shaft of wide gear 131; a narrow gear 141 is fixedly connected to one end of limiting wheel 14 on the outside of guide rail 11 and meshes with wide gear 131, and two limiting cylinders 142 are sleeved on the outside of limiting wheel 14, with multiple rows of first screw holes 143 opened on the outer wall of limiting wheel 14, and multiple through second screw holes 144 opened on the side wall of limiting cylinder 142.

[0026] As described above, the radius difference between the limiting cylinder 142 and the limiting wheel 14 is slightly greater than the thickness of the PE film. The limiting cylinder 142 is in close contact with the heating wheel 13, which is driven to rotate by the first motor 132. The two limiting wheels 14 are driven to rotate through the meshing transmission of the outer wide gear 131 and the two narrow gears 141, so that the PE film passes through the gap between the limiting wheel 14 and the heating wheel 13. The two limiting wheels 14 can restrict a large area of ​​PE film on the surface of the heating wheel 13, so that the PE film can be wound up. The system optimizes the stretch and prevents wrinkles during winding. Two limiting cylinders 142 are fixedly installed on the outer wall of the limiting wheel 14 through the second screw hole 144 and the first screw hole 143. The two sets of limiting cylinders 142 together limit the two sides of the PE film to prevent it from shifting during winding. By rotating the first screw hole 143 to different positions, the limiting cylinders 142 can be installed in different positions to adjust the distance between the two limiting cylinders 142, which is suitable for winding PE films of different widths.

[0027] Please refer to the attached document carefully. Figure 1 , 3As shown in Figures 4 and 5, the driving component 15 includes a first convex disk 151 rotatably mounted on the inner wall of the guide rail 11, a second motor 152 fixedly mounted on one side of the guide rail 11, and the actuating end of the second motor 152 fixedly connected to the central shaft of the first convex disk 151; the clamping component 16 includes multiple electric push rods 161 annularly fixedly mounted on the inner side of the guide rail 11, the actuating ends of the multiple electric push rods 161 being fixedly connected to an annular mounting disk 162, a bearing 163 mounted in the middle of the other side of the annular mounting disk 162, and a second convex disk 164 mounted inside the bearing 163; the winding wheel 17 has a rough surface, and the winding wheel 17 has fitting first... The guide rail 11 has a groove 171 for fitting a convex disc 151 and a second convex disc 164. The bottom of the guide rail 11 is fixedly provided with a sloping groove 172 located at the bottom of the winding wheel 17. The detection component 18 includes two sliding rods 181 arranged vertically and fixed at both ends to the middle of two mounting plates 12. Multiple detection boxes 182 are slidably installed on the outside of the sliding rods 181. A sliding plate 183 is slidably provided inside the detection box 182. A pressure sensor 184 is fixedly installed at the top inside the detection box 182. The bottom of the pressure sensor 184 is connected to the top of the sliding plate 183 by multiple high-precision springs 185. A driven wheel 186 is rotatably mounted on the bottom of the sliding plate 183.

[0028] As described above, the first convex disk 151 and the second convex disk 164 are used to fit the winding wheel 17 into the guide rail 11. After installation, in the normal state, the multiple electric actuators 161 are fully extended, and the winding wheel 17 is fixed. The second motor 152 drives the first convex disk 151 to rotate, which in turn drives the winding wheel 17 and the second convex disk 164 to rotate on one side of the bearing 163, winding up the PE film. The speed of the second motor 152 and the operating status of the multiple electric actuators 161 are controlled by an external PLC component. The pressure reading of the pressure sensor 184 can provide the control and adjustment basis for the PLC component. As the PE film is wound thicker, the top of the PE film pushes the driven wheel 186, causing the sliding plate 183 to gradually sink into the detection box 182. The high-precision spring 185 is gradually compressed, causing the pressure reading on the pressure sensor 184 to gradually increase from the negative value at the beginning of the lifting sliding plate 183. The reading of the pressure sensor 184 is transmitted to the PLC element to continuously control the second motor 152, reducing its speed to adapt to the gradually increasing radius of the PE film roll, preventing the PE film from wrinkling or even tearing due to the increasingly faster winding speed caused by the gradually increasing radius. When the reading of the pressure sensor 184 increases to the value set at which the PE film has been wound up, the PLC element controls multiple electric push rods 161 to retract, driving the annular mounting plate 162, bearing 163 and second convex plate 164 to retract. The winding wheel 17 disengages from the second convex plate 164 and falls onto the inclined groove 172 for discharge.

[0029] The above embodiments are only for illustrating the technical concept of this utility model and should not be used to limit the protection scope of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the protection scope of this utility model.
