Description

Technical Field

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

[0002] As a functional material widely used in electronics, packaging, medical and other fields, the winding process of release film has a significant impact on product quality and production efficiency.

[0003] The prior art includes a PET release film winding mechanism disclosed in patent application number CN202222504200.3, which includes a frame, a motor fixedly installed on the right inner wall of the frame, a first turntable fixedly installed on the output shaft of the motor, a winding roller movably connected to the left side of the first turntable, and a disassembly assembly fixedly installed inside the frame. The disassembly assembly includes a linear guide rail, a support plate, a movable block, an arc-shaped limit block, a slide cylinder, a slide rod, a hydraulic cylinder, and a second turntable. This PET release film winding mechanism uses a second turntable connected to a hydraulic cylinder and slide bar via a fixed plate. This allows the second turntable to be driven by the rotation of the winding roller, ensuring the winding function operates smoothly. Simultaneously, the winding roller can be separated from the second turntable by the extension and retraction of the hydraulic cylinder, facilitating user operation and making the PET release film winding mechanism easier to use. However, this technical solution has two main drawbacks. First, the fixed winding width makes it difficult to adapt to the production needs of different release film specifications. Changing the winding width often requires replacing the entire winding assembly, which is not only cumbersome but also increases production costs and equipment downtime. Second, this technical solution lacks effective cleaning and drying measures for the release film surface. During production, moisture, dust, debris, and other impurities easily adhere to the surface of the release film. If not cleaned promptly, these impurities can cause adhesion between the release film layers during winding, affecting the release film's peeling performance. Furthermore, residual moisture can cause deformation and mold growth in the release film, reducing product quality.

[0004] In view of this, we propose a winding device for the production of release film. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a winding device for the production of release film.

[0006] The technical solution of this utility model is:

[0007] A winding device for release film production includes a base. Two main support frames are symmetrically fixedly mounted on the top of the base. A winding shaft is rotatably mounted between the two main support frames. Several adjustable movable partitions are slidably mounted on the outer circumference of the winding shaft. A winding motor for driving the winding shaft is mounted on one of the main support frames. Four secondary support frames are symmetrically fixedly mounted on the base in front of the main support frames. A guide shaft is rotatably mounted between each pair of opposing secondary support frames. Two symmetrically arranged flow dividers are provided between the two guide shafts. Each flow divider has evenly distributed flow divider holes on its outer wall on one opposite side. The bottom of the outer circumference of the guide shaft is horizontally positioned between the two flow dividers. An air supply assembly for providing hot air to the two flow dividers is mounted on the base. The adjustable spacing of the movable partitions on the winding shaft allows for flexible adjustment of the release film winding width, suitable for the production needs of products with different specifications. The flow divider works in conjunction with the air supply assembly to dry and clean the surface of the release film with hot air, effectively removing moisture, dust and impurities. This avoids interlayer adhesion or surface damage caused by residual contaminants during the winding process, significantly improving the winding quality and flatness of the release film.

[0008] As a preferred technical solution, the air supply assembly includes a heating box fixed on a base, an air inlet at the top of the heating box, and several parallel heating meshes fixedly installed inside the heating box. Both ends of the heating box are equipped with pipe assemblies communicating with two distribution plates, and the pipe assemblies are integrally formed. This achieves efficient heat transfer and uniform distribution, and the parallel arrangement of the heating meshes ensures sufficient air heating, providing a stable hot airflow to the distribution plates and enhancing the drying effect.

[0009] As a preferred technical solution, the piping assembly includes a tee pipe connected and fixed to the heating box. Each of the other two ports of the tee pipe is equipped with a vertical pipe, and each vertical pipe has two air inlet pipes. The two air inlet pipes on the same vertical pipe are respectively connected to two branch pipes. An air pump is installed at the end of the tee pipe connected to the heating box. This combination of the tee pipe and multiple air inlet pipes allows hot air to be simultaneously delivered to the upper and lower branch plates. Powered by the air pump, the airflow pressure is kept stable, further improving the uniformity of the air output from the branch holes.

[0010] As a preferred technical solution, a filter screen is fixedly installed inside the air inlet of the heating chamber, and a protective net is fixedly installed on the outside of the air inlet by bolts. The dual configuration of the filter screen and the protective net effectively filters impurities and large dust particles in the air, preventing them from entering the heating chamber and contaminating the release film surface, thereby improving the cleanliness and quality stability of the product.

[0011] As a preferred technical solution, each end of the take-up shaft is integrally formed with an end shaft, and a connecting shaft is rotatably mounted on the inner wall of each of the two main support frames. The two end shafts are coaxially fixed to the two connecting shafts by bolts, and one of the connecting shafts is coaxially fixed to the output shaft of the take-up motor. The bolt connection between the end shafts and the connecting shafts facilitates the quick disassembly and replacement of the take-up shaft, improving equipment maintenance efficiency.

[0012] As a preferred technical solution, a fixed partition is fixedly connected to each end of the outer circumference of the take-up shaft to restrict the ends of the take-up shaft. Each fixed partition is provided with a lifting hole near its edge. The design of the lifting hole facilitates the use of lifting equipment to move the take-up shaft, thereby improving the ease of operation.

[0013] As a preferred technical solution, the outer circumference of the take-up shaft is provided with the same number of strip grooves as the movable partitions. Each movable partition has a drive block integrally formed on its inner ring wall, and several drive blocks are slidably connected to several strip grooves. The sliding cooperation between the strip grooves and the drive blocks provides precise guidance for the movable partitions, ensuring their smooth movement on the take-up shaft and guaranteeing the accuracy of the take-up width adjustment.

[0014] As a preferred technical solution, an adjusting screw is rotatably installed in each of the strip slots. The drive block is threadedly connected to the adjusting screw. One end of the adjusting screw extends to the outside of the take-up shaft and is rotatably connected to the take-up shaft via a bearing. A screw head is integrally formed on the outer end of the adjusting screw on the same axis. The threaded connection between the adjusting screw and the drive block enables precise positioning and fixing of the movable partition. The screw head design facilitates manual or tool operation, simplifies the adjustment process, and improves production efficiency.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention features an adjustable spacing design for the movable partitions on the winding shaft, enabling flexible adjustment of the release film winding width to meet the production needs of products with different specifications. The diverter plate, in conjunction with the air supply assembly, utilizes hot air to dry and clean the release film surface, effectively removing moisture, dust, and impurities. This prevents interlayer adhesion or surface damage caused by residual contaminants during winding, significantly improving the winding quality and flatness of the release film.

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] Please refer to the accompanying drawings. This utility model provides a technical solution:

[0025] like Figure 1 and Figure 2As shown, a winding device for release film production includes a base 1. Two main support frames 4 are symmetrically fixedly mounted on the top of the base 1. A winding shaft 5 is rotatably mounted between the two main support frames 4. Several adjustable movable partitions 51 are slidably mounted on the outer circumference of the winding shaft 5. A winding motor 40 for driving the winding shaft 5 is mounted on one of the main support frames 4. Four auxiliary support frames 2 are symmetrically fixedly mounted on the base 1 in front of the main support frames 4. A guide shaft 20 is rotatably mounted between each pair of opposite auxiliary support frames 2. Two symmetrically arranged diverting plates 3 are provided between the two guide shafts 20. The outer walls of the two diverting plates 3 on opposite sides have evenly distributed diverting holes. The bottom of the outer circumference of the guide shaft 20 is horizontally positioned between the two diverting plates 3. An air supply assembly for providing hot air to the two diverting plates 3 is mounted on the base 1. The adjustable spacing of the movable partitions 51 on the winding shaft 5 allows for flexible adjustment of the release film winding width, suitable for the production needs of products with different specifications. The flow divider 3 works in conjunction with the air supply assembly to dry and clean the surface of the release film with hot air, effectively removing moisture, dust and impurities. This avoids interlayer adhesion or surface damage caused by residual contaminants during the winding process, significantly improving the winding quality and flatness of the release film.

[0026] like Figure 1 and Figure 4 As shown, in a preferred embodiment, the air supply assembly includes a heating box 30 fixed on the base 1. The heating box 30 has an air inlet 37 at its top. Several parallel heating meshes 36 are fixedly installed inside the heating box 30. Both ends of the heating box 30 are equipped with pipe assemblies that communicate with both diverter plates 3. These pipe assemblies are integrally formed. This achieves efficient heat transfer and uniform distribution. The parallel arrangement of the heating meshes 36 ensures sufficient air heating, providing a stable hot airflow to the diverter plates 3 and enhancing the drying effect.

[0027] It should be noted that the two flow dividers 3 are supported by pads 31 located at the four corners.

[0028] like Figure 1 As shown, in a preferred embodiment, the piping assembly includes a three-way pipe 34 that is connected to and fixed to the heating box 30. Each of the other two ports of the three-way pipe 34 is equipped with a vertical pipe 33. Each vertical pipe 33 has two air inlet pipes 32 installed on it. The two air inlet pipes 32 on the same vertical pipe 33 are respectively connected to two branch pipes. An air pump 35 is installed at the end of the three-way pipe 34 connected to the heating box 30. The combination of the three-way pipe 34 and the multiple air inlet pipes 32 allows hot air to be synchronously delivered to the upper and lower branch plates 3. Power is provided by the air pump 35, ensuring the stability of the airflow pressure and further improving the uniformity of the air output from the branch holes.

[0029] like Figure 4As shown, in a preferred embodiment, a filter screen 38 is fixedly installed inside the air inlet 37 of the heating chamber 30, and a protective net 39 is fixedly installed on the outside of the air inlet 37 by bolts. The dual arrangement of the filter screen 38 and the protective net 39 effectively filters impurities and large dust particles in the air, preventing them from entering the heating chamber 30 and contaminating the release film surface, thereby improving the cleanliness and quality stability of the product.

[0030] like Figure 2 As shown in the preferred embodiment, both ends of the take-up shaft 5 are integrally formed with an end shaft 53, and a connecting shaft 41 is rotatably mounted on the inner wall of each of the two main support frames 4. The two end shafts 53 are coaxially fixed to the two connecting shafts 41 by bolts, and one of the connecting shafts 41 is coaxially fixed to the output shaft of the take-up motor 40. The bolt connection between the end shafts 53 and the connecting shafts 41 facilitates the quick disassembly and replacement of the take-up shaft 5, improving equipment maintenance efficiency.

[0031] like Figure 2 As shown, in a preferred embodiment, a fixed partition 50 is fixedly connected to both ends of the outer circumference of the take-up shaft 5 to restrict the ends of the take-up shaft 5. Each fixed partition 50 is provided with a lifting hole 500 near the edge. The design of the lifting hole 500 facilitates the use of lifting equipment to move the take-up shaft 5, thereby improving the ease of operation.

[0032] like Figure 3 As shown, in a preferred embodiment, the outer circumference of the take-up shaft 5 is provided with the same number of strip grooves 54 as the movable partitions 51. Each movable partition 51 has a drive block 510 integrally formed on its inner ring wall, and several drive blocks 510 are slidably connected to several strip grooves 54. The sliding engagement between the strip grooves 54 and the drive blocks 510 provides precise guidance for the movable partitions 51, ensuring their smooth movement on the take-up shaft 5 and guaranteeing the accuracy of the take-up width adjustment.

[0033] like Figure 3 As shown, in a preferred embodiment, each strip groove 54 has an adjusting screw 52 rotatably installed within it. The drive block 510 is threadedly connected to the adjusting screw 52. One end of the adjusting screw 52 extends to the outside of the winding shaft 5 and is rotatably connected to the winding shaft 5 via a bearing. A screw head is integrally formed on the outer end of the adjusting screw 52. The threaded connection between the adjusting screw 52 and the drive block 510 enables precise positioning and fixation of the movable partition 51. The screw head design facilitates manual or tool operation, simplifies the adjustment process, and improves production efficiency.

[0034] In the production of release film, the winding device of this invention operates as follows: During the winding preparation stage, the operator, according to the width specifications of the release film, drives the movable partition 51 to slide along the strip groove 54 on the winding shaft 5 by rotating the screw head outside the adjusting screw 52. The spacing between the movable partitions 51 is adjusted to determine the winding width, and the fixed partition 50 restricts the sliding range of the movable partitions 51. Using a hoisting device, the winding shaft 5 is installed onto the connecting shaft 41 of the main support frame 4 through the hoisting holes 500 on the fixed partition 50 and secured with bolts. After being output from the production equipment, the release film sequentially passes around the two guide shafts 20 from the bottom and passes between the two diverter plates 3. After the air supply assembly is started, the air pump 35 draws in outside air through the air inlet 37 at the top of the heating box 30. The air is filtered and purified by the protective net 39 and the filter 38. The parallel heating net 36 inside the heating box 30 fully heats the air to form a hot airflow. The hot airflow is simultaneously delivered to the upper and lower distribution plates 3 through the three-way pipe 34, the vertical pipe 33, and the air inlet pipe 32. The distribution plates 3 spray the hot air onto the upper and lower surfaces of the release film through the distribution holes, achieving drying, dust removal, and impurity removal. The winding motor 40 drives the connecting shaft 41 to rotate the winding shaft 5 to wind up the release film. The movable partition 51 rotates synchronously with the release film to ensure neat edges. After winding is completed, the bolts at both ends of the winding shaft 5 are removed, and the winding shaft 5 and the release film roll are lifted off through the lifting holes 500 for quick replacement with a new winding shaft 5. This device achieves flexible adjustment of the release film winding width, efficient surface cleaning and drying, and quick replacement and maintenance of the winding shaft 5 through the above process, improving production quality and efficiency.
