Description

Technical Field

[0001] The utility model relates to the technical field of composite film winding, in particular to a winding device for composite film production. Background Art

[0002] Composite membranes are polymer materials formed by combining two or more thin layers of different materials through a specific process. Their structural characteristics include a dense, homogeneous membrane overlaid on a microporous or ultrafiltration membrane, or formed by extrusion or gluing onto other substrates. Composite membranes offer high strength, tear resistance, acid and alkali resistance, corrosion resistance, aging resistance, and excellent impermeability. They are widely used in packaging, reverse osmosis, gas separation, water conservancy, municipal administration, construction, transportation, and other fields. During the composite membrane production process, winding equipment is required to wind the composite membrane.

[0003] For example, a Chinese patent disclosure: a composite film winding device, application number: CN202321400667.1, includes a processing table and a composite film body at the front end of the processing table, a winding assembly is provided on the top rear side of the processing table, a processing groove is vertically opened downward from the top of the processing table, and a feed port is opened through the lower end of the inner side of the processing groove; at least two groups of cleaning components are arranged in sequence from bottom to top on the inner side of the processing groove, and a guide groove connected to the inside of the processing groove is opened through the bottom of one side of the processing table, and a collection box is provided inside the guide groove; in this utility model, this device can improve the quality and production efficiency of the composite film, while reducing noise, providing a better working environment for operators, and at the same time, the low noise and energy-saving and high-efficiency characteristics help to reduce the operating cost of the equipment. The convenient operation design also helps to improve the efficiency and safety of the equipment.

[0004] However, in the above technical solution, when the composite film needs to be rolled up using a winding device, it needs to be fixed by a reel. Since the air expansion shaft has a wide range of applications, most of the air expansion shafts on the market are used to fix the reel. After the current winding equipment is wound up, the air expansion shaft needs to be disassembled first, and then the rolled composite film can be removed from the air expansion shaft. However, the air expansion shaft is relatively heavy, so when disassembling the air expansion shaft, most of the time, it is necessary to use an external machine for assistance, which not only increases the cost, but also requires great care during the disassembly of the air expansion shaft, so it takes a lot of time, thereby reducing work efficiency. Utility Model Content

[0005] The main purpose of the present invention is to provide a winding device for composite film production, which can effectively solve the problem in the background technology that when the composite film needs to be wound up by the winding device, it needs to be fixed by a reel. Since the air expansion shaft has a wide range of applications, the air expansion shaft is mostly used to fix the reel on the market. After the winding is completed, the current winding device first needs to disassemble the air expansion shaft, and then the rolled composite film can be removed from the air expansion shaft. However, the air expansion shaft is relatively heavy, so when disassembling the air expansion shaft, most of the time it is necessary to use an external machine for assistance, which not only increases the cost, but also requires great caution during the disassembly of the air expansion shaft, so it takes a lot of time, thereby reducing work efficiency.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A winding device for composite film production includes a base, on which an air inflation shaft and several tensioning rollers are rotatably arranged, a motor is arranged on one side of the air inflation shaft, a first slide groove is arranged on one side of the base, a support plate is slidingly arranged in the first slide groove, a first through groove and a second through groove are arranged on the support plate, a clamping assembly is arranged on one side of the support plate, and a hydraulic rod is fixedly arranged on the outer wall surface of one side of the support plate.

[0008] Preferably, the side of the pneumatic shaft away from the motor is located in the first through groove, the motor is fixedly mounted on the base, the support plate is concave in shape, the side of the pneumatic shaft close to the motor is located in the second through groove, and the hydraulic rod is fixedly mounted on the base.

[0009] Preferably, the second through slot is located between the first through slot and the motor.

[0010] Preferably, the clamping assembly is fixedly provided with two support columns on the support plate, the support columns are provided with second sliding grooves, and a sliding column is slidably provided in the second sliding grooves.

[0011] Preferably, a spring is fixedly provided on one side of the slide post, and a pressure roller is rotatably provided between the two slide posts.

[0012] Preferably, the spring is fixedly connected to the inner wall of the second sliding groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) After the winding is completed, the utility model releases the clamping of the air-expanding shaft on the reel, and then the support plate is moved along the trajectory of the first slide groove in the direction away from the motor by the hydraulic rod, thereby releasing the support of the first through groove on the side of the air-expanding shaft away from the motor. At the same time, the support plate squeezes the rolled composite film, so that the rolled composite film gradually leaves the air-expanding shaft, and the second through groove replaces the support of the first through groove on the side of the air-expanding shaft away from the motor. In this way, the rolled composite film can be removed from the air-expanding shaft without disassembling the air-expanding shaft. Not only does it not need to use an external machine to disassemble the air-expanding shaft, thus saving costs, but it can also quickly load and unload materials, greatly improving work efficiency.

[0015] (2) The utility model uses the elastic force of the spring to make the pressure roller always close to the composite film rolled on the air-expanding shaft, so that the rolled composite film is pressed by the pressure roller. At the same time, as the diameter of the composite film rolled on the air-expanding shaft becomes larger and larger, the deformation amplitude of the spring becomes larger, and the pressure of the pressure roller becomes larger. Therefore, the pressure of the pressure roller changes with the diameter of the rolled composite film, making the rolled product more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1 and Figure 2As shown, a winding device for composite film production includes a base 1, on which an air-inflating shaft 2 and a plurality of tensioning rollers 3 are rotatably arranged, a motor 4 is arranged on one side of the air-inflating shaft 2, a first slide 5 is arranged on one side of the base 1, a support plate 6 is slidingly arranged in the first slide 5, a first through groove 7 and a second through groove 8 are arranged on the support plate 6, a clamping assembly 9 is arranged on one side of the support plate 6, and a hydraulic rod 10 is fixedly arranged on the outer wall surface of one side of the support plate 6.

[0022] like Figure 3 As shown, in another embodiment of the present invention, the pressing assembly 9 is fixedly provided with two support columns 901 on the support plate 6, and the support columns 901 are provided with second sliding grooves 902, and a sliding column 903 is slidably provided in the second sliding grooves 902;

[0023] A spring 904 is fixedly provided on one side of the slide post 903, and a pressure roller 905 is rotatably provided between the two slide posts 903;

[0024] The elastic force of spring 904 ensures that the pressure roller 905 is always in close contact with the composite film rolled on the air-expanding shaft 2, thereby pressing the rolled composite film through the pressure roller 905. At the same time, as the diameter of the composite film rolled on the air-expanding shaft 2 becomes larger and larger, the deformation amplitude of spring 904 becomes larger, which makes the pressure of the pressure roller 905 greater. Therefore, the pressure of the pressure roller 905 changes with the diameter of the rolled composite film, making the rolled product more stable.

[0025] The working principle of this composite film production winding equipment:

[0026] When in use, the roll is first clamped by the air expansion shaft 2, and then the composite film is passed through several tensioning rollers 3 and then attached to the roll, and then the air expansion shaft 2 is rotated by the motor 4 to reel the composite film. During the reeling process, the reeled composite film is pressed by the pressing component 9. After the reeling is completed, the air expansion shaft 2 is released from the clamping of the reel, and then the support plate 6 is moved along the trajectory of the first slide groove 5 in the direction away from the motor 4 by the hydraulic rod 10, and the support of the first through groove 7 on the side of the air expansion shaft 2 away from the motor 4 is released. At the same time, the support plate 6 squeezes the reeled composite film, so that the reeled composite film gradually leaves the air expansion shaft 2, and the second through groove 8 replaces the support of the first through groove 7 on the side of the air expansion shaft 2 away from the motor 4, so that the reeled composite film can be removed from the air expansion shaft 2 without disassembling the air expansion shaft 2. Not only does it not need to use an external machine to disassemble the air expansion shaft 2, which saves costs, but it can also quickly load and unload materials, greatly improving work efficiency.

[0027] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. Any obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
