Technical Field
[0001] This utility model relates to the field of film winding technology, and in particular to a film winding and changing frame. Background Technology
[0002] Thin film is a two-dimensional material with extremely thin thickness, flexibility, and specific functions (such as barrier and optical properties), widely used in packaging, electronics, and industrial fields. The film winding rack is the core equipment at the end of the production line that winds finished films into rolls. Its core technology lies in ensuring that the rolls are tightly packed, neat, and undamaged through precise tension, pressure, and web guiding control, thereby guaranteeing the quality of film products during storage, transportation, and subsequent processing.
[0003] In the process of developing this application, the inventors discovered the following problems with the prior art: Currently, most existing film winding racks use a fixed structure to install and fix the winding shaft when the film is wound and stored. Since different films require winding shafts of different specifications during the winding process, the fixed structure is difficult to install and fix winding shafts of different lengths. Therefore, those skilled in the art have provided a film winding and changing rack to solve the problems mentioned in the background art. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a film winding and changing frame. The adjustment plate set on the upper surface of the base plate can drive the mounting frame to move in position, so that the mounting frame can install and fix the winding shaft of different specifications. At the same time, the adjustment rod set in the mounting frame can assist the winding shaft by rotating the set roller shaft, which can better wind and store the film. The two support mechanisms set can provide auxiliary support for the winding shaft.
[0005] To achieve the above objectives, the present invention provides the following technical solution: A film winding and changing frame includes a base plate, a bidirectional screw is provided at the midpoint of the upper surface of the base plate, adjusting plates are provided on both sides of the upper surface of the base plate, a mounting frame is provided on one side of the upper surface of each of the two adjusting plates, an adjusting rod is provided at the upper end of the front end of the front end of each of the two mounting frames, a guide rod is provided on the front end of the rear end of each of the two mounting frames, and a first spring is provided on the outer surface of each of the two guide rods. A support mechanism is provided on the side of the upper surface of the two adjustment plates away from the mounting frame. The two support mechanisms include an upper fixing plate. A support block is provided on the upper surface of the two upper fixing plates. Telescopic rods are provided at the front end and rear end of the lower surface of the two upper fixing plates. A lower fixing plate is provided on the lower surface of the telescopic rod located in the same support mechanism. A second spring is sleeved on the outer surface of the four telescopic rods.
[0006] Furthermore, the upper and lower ends of the four second springs are respectively fixedly mounted on the upper and lower ends of the four telescopic rods, the upper ends of the four telescopic rods are fixedly mounted on the front and rear ends of the lower end faces of the two upper fixing plates, and the lower ends of the four telescopic rods are respectively fixedly mounted on the front and rear ends of the upper end face of the lower fixing plate.
[0007] Furthermore, both support blocks are fixedly mounted at the midpoint of the upper end face of the upper fixed plate, and multiple rollers are rotatably embedded inside the upper end face of both support blocks. The two lower fixed plates are respectively fixedly mounted on one side of the upper end face of the two adjusting plates.
[0008] Furthermore, the two adjusting rods are respectively movably embedded in the upper side of the front end face of the two mounting brackets, the two guide rods are respectively fixedly installed in the upper side of the rear end face of the two mounting brackets, the rear ends of the two adjusting rods are respectively movably sleeved on the outer surface of the two guide rods, and a roller is rotatably arranged between the front ends of the two adjusting rods on opposite sides.
[0009] Furthermore, the front ends of the two first springs are fixedly disposed on the upper side of the rear end face of the two mounting brackets, and the rear ends of the two first springs are respectively fixedly disposed on the rear end face of the two adjusting rods.
[0010] Furthermore, the bidirectional screw is rotatably embedded at the midpoint of the upper surface of the base plate, and a servo motor is fixedly installed at the midpoint of one side of the upper surface of the base plate. The output end of the servo motor is fixedly connected to one end of the bidirectional screw.
[0011] Furthermore, the two adjustment plates are respectively movably embedded on both sides of the upper surface of the base plate, and the two adjustment plates are respectively threaded onto both sides of the outer surface of the bidirectional screw at the midpoint of the lower end. The upper surfaces of the two mounting brackets are fixed with mounting blocks by bolts.
[0012] This utility model has the following beneficial effects: 1. The film winding and changing frame proposed in this utility model, after setting a bidirectional screw and an adjusting plate on the upper end face of the base plate, allows the servo motor to drive the adjusting plate to move in position via the bidirectional screw. The mounting frame fixed on the upper end face of the adjusting plate can also move in position under the action of the adjusting plate. This allows the mounting frame to install winding shafts of different specifications after the position is moved, thereby making the winding changer more adaptable to films of different widths. At the same time, after setting an adjusting rod at the upper end of the front end face of the mounting frame, the roller set between the two adjusting rods can be brought into contact with the winding shaft. The first spring set between the adjusting rod and the mounting frame can drive the roller to contact the outer surface of the winding shaft, which can play an auxiliary winding role.
[0013] 2. The film winding and changing frame proposed in this utility model can effectively provide auxiliary support to the winding shaft by installing a fixed support mechanism on one side of the upper end face of the adjusting plate. As the winding shaft gradually thickens, the support block and roller in the support mechanism can always be in contact with the lower end face of the winding shaft through the telescopic rod and the second spring, thereby providing better auxiliary support to the winding shaft.

[0016] 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.
[0017] Reference Figures 1 to 6 A film winding and changing frame includes a base plate 1, a bidirectional screw 8 at the midpoint of the upper end face of the base plate 1, adjusting plates 6 on both sides of the upper end face of the base plate 1, mounting brackets 5 on one side of the upper end face of each of the two adjusting plates 6, adjusting rods 3 on the upper end of the front end face of each of the two mounting brackets 5, guide rods 10 on the front end side of the rear end face of each of the two mounting brackets 5, and a first spring 11 on the outer surface of each of the two guide rods 10. Support mechanisms 7 are provided on the side of the upper end face of the two adjusting plates 6 away from the mounting frame 5. The two support mechanisms 7 include upper fixing plates 702. Support blocks 701 are provided on the upper end face of the two upper fixing plates 702. Telescopic rods 703 are provided at the front end and rear end face of the lower end face of the two upper fixing plates 702. Among the four telescopic rods 703, the lower end face of the telescopic rod 703 located in the same support mechanism 7 is provided with a lower fixing plate 706. A second spring 705 is sleeved on the outer surface of the four telescopic rods 703.
[0018] Specifically, after a bidirectional screw 8 is rotatably embedded in the upper end face of the base plate 1, the bidirectional screw 8 can drive the adjusting plates 6, which are movably embedded in both sides of the upper end face of the base plate 1, to move their positions. This allows the mounting brackets 5 and the support mechanism 7 on the upper end face of the adjusting plates 6 to move their positions, enabling the mounting brackets 5 to be adapted to the winding shafts of different lengths. At the same time, the support mechanism 7 can provide auxiliary support for the winding shaft that becomes thicker after winding. The support mechanism 7 can also use a second spring 705 to ensure that the support block 701 is always in contact with the outer surface of the winding shaft, providing auxiliary support for the winding shaft. The two mounting brackets 5 are fixed at the upper end, and after an adjusting rod 3 is movably embedded in the upper end of the support bracket, a roller 2 of the same length as the winding shaft can be rotatably embedded between the two adjusting rods 3. At the same time, after a first spring 11 is set between the rear end of the adjusting rod 3 and the rear end face of the upper end of the support bracket, the roller 2 can be in contact with the outer surface of the winding shaft, thereby providing auxiliary winding for the winding shaft.
[0019] Reference Figure 2 and Figure 6 The upper and lower ends of the four second springs 705 are respectively fixedly installed on the upper and lower ends of the four telescopic rods 703. The upper ends of the four telescopic rods 703 are fixedly installed on the front and rear ends of the lower end face of the two upper fixing plates 702. The lower ends of the four telescopic rods 703 are respectively fixedly installed on the front and rear ends of the upper end face of the lower fixing plate 706.
[0020] Specifically, after the upper and lower ends of the second spring 705 are installed and fixed to the upper and lower ends of the telescopic rod 703, the telescopic rod 703 can guide the second spring 705, effectively preventing the second spring 705 from shifting when it retracts. The telescopic rod 703 can be configured in multiple stages to improve its telescopic effect. After the upper and lower ends of the telescopic rod 703 are fixedly connected to the upper fixing plate 702 and the lower fixing plate 706 respectively, the second spring 705 can work together to provide auxiliary support for the upper fixing plate 702. This allows the support block 701 installed on the upper end of the upper fixing plate 702 to better contact the outer surface of the winding shaft, providing auxiliary support for the winding shaft.
[0021] Reference Figure 2 and Figure 6 Both support blocks 701 are fixedly installed at the midpoint of the upper end face of the upper fixed plate 702. Multiple rollers 704 are rotatably embedded inside the upper end face of both support blocks 701. The two lower fixed plates 706 are respectively fixedly installed on one side of the upper end face of the two adjusting plates 6.
[0022] Specifically, after the support block 701 is installed and fixed on the upper end face of the upper fixing plate 702, multiple rollers 704 can be rotatably embedded on the upper end face of the support block 701. The support block 701 with the rotatable rollers 704 can fit against the lower end of the outer surface of the take-up shaft under the push of the second spring 705, which can provide auxiliary support for the take-up shaft. The rollers 704 can prevent the support block 701 from affecting the rotation of the take-up shaft. After the lower fixing plate 706 is installed and fixed on the upper end of the adjusting plate 6, the adjusting plate 6 can better drive the support mechanism 7 to move in position, providing auxiliary support for take-up shafts of different specifications.
[0023] Reference Figure 4 and Figure 5 Two adjusting rods 3 are respectively movably embedded in the upper side of the front end face of the two mounting brackets 5, and two guide rods 10 are respectively fixedly set in the upper side of the rear end face of the two mounting brackets 5. The rear ends of the two adjusting rods 3 are respectively movably sleeved on the outer surface of the two guide rods 10, and a roller 2 is rotatably arranged between the front ends of the two adjusting rods 3 on opposite sides.
[0024] Specifically, after the adjusting rod 3 is movably embedded in the upper part of the front end face of the mounting frame 5, a fixed guide rod 10 can be installed in the upper part of the rear end face of the mounting frame 5. At the same time, the adjusting rod 3, which is movably inserted through the rear end, is movably sleeved on the outer surface of the guide rod. The guide rod 10 can guide the movement of the adjusting rod 3 and prevent the guide rod 10 from deviating. Meanwhile, a roller 2 is rotatably embedded between the front ends of the two adjusting rods 3 on opposite sides. The roller 2 can fit against the outer surface of the take-up shaft, thereby assisting the take-up shaft in winding. The embedded roller 2 is the same length as the take-up shaft, and the roller 2 can be replaced according to the length of the take-up shaft to better fit the roller 2 against the take-up shaft.
[0025] Reference Figure 1 and Figure 5 The front ends of the two first springs 11 are fixedly mounted on the upper side of the rear end face of the two mounting brackets 5, and the rear ends of the two first springs 11 are respectively fixedly mounted on the rear end face of the two adjusting rods 3.
[0026] Specifically, after the front end and rear end of the first spring 11 are fixedly connected to the rear end face of the mounting frame 5 and the rear end of one side of the adjusting rod 3, the first spring 11 can push and the adjusting rod 3 to move on the outer surface of the guide rod 10, so that the outer surface of the roller 2 and the take-up shaft set between the two adjusting rods 3 can be put into contact. Under the action of the first contact, the roller 2 can adaptively contact the take-up shaft of different thicknesses to assist in the take-up.
[0027] Reference Figure 1 and Figure 4 The bidirectional screw 8 is rotatably embedded at the midpoint of the upper surface of the base plate 1. A servo motor 9 is fixedly installed at the midpoint of one side of the upper surface of the base plate 1. The output end of the servo motor 9 is fixedly connected to one end of the bidirectional screw 8.
[0028] Specifically, after the bidirectional screw 8 is rotatably embedded at the midpoint of the upper end face of the base plate 1, a servo motor 9 can be fixedly installed at the midpoint of one side of the upper end face of the base plate 1. After the output end of the servo motor 9 is fixedly connected to one end of the bidirectional screw 8, the servo motor 9 can drive the bidirectional screw 8 to rotate. At the same time, the servo motor 9 adopts the existing conventional technical solution. A controller is set on one side of the upper end face of the base plate 1. The controller can be electrically connected to the servo motor 9, and the controller also adopts the existing conventional technical solution. The controller can control the on / off, speed and rotation direction of the servo motor 9.
[0029] Reference Figure 1 and Figure 5 Two adjusting plates 6 are respectively movably embedded on both sides of the upper end face of the base plate 1. The two adjusting plates 6 are respectively threaded on both sides of the outer surface of the bidirectional screw 8 at the lower midpoint. The upper end face of the two mounting brackets 5 is fixed with mounting blocks 4 by bolts.
[0030] Specifically, the bidirectional screw 8 and the adjusting plates 6 movably embedded on both sides of the upper end face of the base plate 1 are threaded together, so that the bidirectional screw 8 can drive the two adjusting plates 6 to move in position. At the same time, the threaded grooves on both sides of the outer surface of the bidirectional screw 8 are opposite, so that when it rotates, it can drive the two sleeved adjusting plates 6 to move in opposite directions. On both sides of the take-up shaft set on the upper end face of the two mounting brackets 5, the rotating shaft can better allow the take-up shaft to rotate on the upper end of the two mounting brackets 5. At the same time, the mounting block 4 is embedded in the upper end face of the mounting bracket 5. The mounting block 4 can better install and fix the take-up shaft with bearings by bolts, so as to prevent the take-up shaft from falling off during rotation. The take-up shaft can be connected to an external independent transmission device, so that the independent transmission device can drive the take-up shaft to roll up and collect the film.
[0031] Working principle: In use, the operator can first fix the base in a suitable position with bolts, and then put bearings on both sides of the take-up shaft to be used for winding. After the servo motor 9 is started by the controller, the servo motor 9 can drive the two adjusting plates 6 to move in opposite directions through the bidirectional screw 8. After moving to a suitable position, the take-up shaft with bearings can be placed at the midpoint of the upper end face of the two mounting brackets 5, so that the outer surface of the two bearings is in contact with the upper end face of the mounting bracket 5. At this time, the operator can use the mounting block 4 to install and fix the upper end face of the mounting bracket 5 with bolts to fix the take-up shaft and bearings. After fixing, the operator can use an independent transmission device to connect with the take-up shaft, so that the take-up shaft can rotate and wind up. At the same time, the operator can pass the film to be wound through the lower end of the roller 2 and connect it to the take-up shaft, so that the take-up shaft can wind up and store the film.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
