Description

Technical Field

[0001] This utility model relates to the field of composite material processing technology, specifically to an adjustable tension automated control unidirectional belt film spreading mechanism. Background Technology

[0002] In the production process of composite materials, unidirectional tape spreading is an important step. Unidirectional tape is usually a strip made of fiber material. During the spreading process, it is necessary to maintain appropriate tension to ensure the quality and accuracy of spreading. However, existing unidirectional tape spreading mechanisms have some problems in use.

[0003] The installation and removal of the rollers in traditional film spreading mechanisms usually require a lot of manual operation, which is cumbersome and time-consuming, affecting production efficiency. Existing film spreading mechanisms are difficult to flexibly adjust the tension according to different production needs. Insufficient tension can easily cause wrinkles in the unidirectional belt, affecting the flatness and quality of the material; while excessive tension may cause the material to break, resulting in waste of raw materials and production interruption.

[0004] Therefore, it is necessary to propose an adjustable tension automated control unidirectional belt film spreading mechanism. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an adjustable tension automated control unidirectional belt film spreading mechanism, which has the advantages of easy assembly and disassembly of the roll and the ability to adjust the tension as needed, thus solving the problems mentioned in the background technology.

[0006] This utility model provides the following technical solution: an adjustable tension automated control unidirectional belt film spreading mechanism, including a base:

[0007] The base is provided with an unwinding mechanism and a winding mechanism on both sides respectively. A guide roller group is provided on one side of the unwinding mechanism and a film spreading roller group is provided on the other side of the guide roller group. A guide roller group is provided on one side of the winding mechanism.

[0008] The unwinding mechanism and the rewinding mechanism have the same structural features. The unwinding mechanism and the rewinding mechanism include a winding roller. Slide grooves are provided on both sides of the base. A bidirectional lead screw is rotatably connected inside the slide groove. Sliding blocks are threaded to the outer surfaces of both ends of the bidirectional lead screw. A bearing block is fixedly connected to the upper surface of the sliding block. A bearing rod is rotatably sleeved inside the upper end of the bearing block. A cross slot is provided at the inner end of the bearing rod. Cross inserts are fixedly connected to both ends of the winding roller. The outer surface of the cross insert is inserted into the inside of the cross slot.

[0009] Preferably, a bearing frame is fixedly connected to the middle of both sides of the base. A connecting rod is fixedly connected inside the bearing frame. A moving block is slidably connected to the outer surface of the connecting rod. The outer surfaces of both sides of the moving block are slidably connected to the inside of the bearing frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This adjustable tension automated unidirectional belt film spreading mechanism, in use, utilizes the identical structure of the unwinding and rewinding mechanisms. During installation, the roll is placed between two sets of support blocks. The bidirectional screw is controlled to drive the two sets of support blocks synchronously, causing the cross-shaped inserts on both sides of the roll to engage with the cross-shaped slots on the support rods of the support blocks. This completes the assembly of the unwinding and rewinding mechanisms. The unidirectional belt starts from the unwinding mechanism, winds as shown in the diagram, and connects to the rewinding mechanism. During film spreading, the tension adjusting roller is driven up and down by an electric push rod to adjust the tension of the unidirectional belt. This structure allows for convenient assembly and disassembly of the rolls on the unwinding and rewinding mechanisms, reducing manual operation time and improving production efficiency. Simultaneously, the tension can be flexibly adjusted according to different production needs, preventing wrinkles due to insufficient tension or material breakage due to excessive tension, thus ensuring film spreading quality.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4An adjustable tension automated control unidirectional belt film spreading mechanism includes a base 1:

[0028] The base 1 is provided with an unwinding mechanism 2 and a winding mechanism 3 on both sides respectively. The unwinding mechanism 2 is provided with a guide roller group 4 on one side and a film spreading roller group 5 on the other side. The winding mechanism 3 is provided with a guide roller group 4 on one side.

[0029] The unwinding mechanism 2 and the winding mechanism 3 have the same structural features. Both include a winding roller 140. Slide grooves 110 are provided on both sides of the base 1. A bidirectional lead screw 111 is rotatably connected inside the slide groove 110. Sliding blocks 120 are threaded onto the outer surfaces of both ends of the bidirectional lead screw 111. A bearing block 130 is fixedly connected to the upper surface of the sliding block 120. A bearing rod 131 is rotatably sleeved inside the upper end of the bearing block 130. A cross slot 1311 is provided at the inner end of the bearing rod 131. Cross inserts 141 are fixedly connected to both ends of the winding roller 140. The outer surface of the cross insert 141 is inserted into the interior of the cross slot 1311. Bearing frames 6 are fixedly connected to the middle positions of both sides of the base 1. The interior of the bearing frames 6 is fixedly connected to... A connecting rod 630 is connected, and a moving block 640 is slidably connected to the outer surface of the connecting rod 630. The two outer surfaces of the moving block 640 are slidably connected to the interior of the bearing frame 6. A tension adjusting roller 650 is fixedly connected to the opposite side of the moving block 640. A mounting plate 610 is fixedly connected to the lower outer side of the bearing frame 6. An electric push rod 620 is mounted on the mounting plate 610. A connecting plate 641 is fixedly connected to the outer side of the moving block 640. The lower surface of the connecting plate 641 is fixedly connected to the output end of the electric push rod 620. A motor 7 is mounted on the side of the base 1. The output shaft of the motor 7 is connected to the end of the bidirectional lead screw 111 through a coupling. A motor 7 is mounted on the side of the bearing block 130. The output shaft of the motor 7 is connected to the end of the bearing rod 131 through a coupling.

[0030] according to Figure 4 It can be seen that the unidirectional belt starts from the unwinding mechanism 2's winding roller 140, is guided by the guide roller group 4 on one side, enters the film spreading roller group 5 for film spreading, and then passes through the guide roller group 4 on one side of the winding mechanism 3, and finally winds onto the winding roller 140 of the winding mechanism 3.

[0031] The motors 7 in the unwinding mechanism 2 and the winding mechanism 3 drive the bearing rod 131 and the bidirectional lead screw 111 respectively, providing power for the rotation and position adjustment of the winding roller 140; the lifting and lowering of the tension adjusting roller 650 is driven by the electric push rod 620.

[0032] In use, the roller 140 is placed between two sets of bearing blocks 130, and the motor 7 is started to drive the bidirectional lead screw 111 to rotate. Since the threads at both ends of the bidirectional lead screw 111 are opposite, the sliding blocks 120 on both sides move inward synchronously, so that the cross-shaped inserts 141 at both ends of the roller 140 are inserted into the cross-shaped slots 1311 of the bearing rod 131 to complete the fixation. In disassembly, the bidirectional lead screw 111 is rotated in the opposite direction, and the sliding blocks 120 drive the bearing blocks 130 to move outward, so that the roller 140 can be taken out. The motor 7 on the side of the bearing block 130 drives the bearing rod 131 to rotate through the coupling, thereby driving the roller 140 to rotate, realizing the unwinding or rewinding action of the unidirectional belt.

[0033] The electric push rod 620 is mounted on the mounting plate 610, and its output end is connected to the connecting plate 641. The connecting plate 641 is fixed on the outside of the moving block 640. When the electric push rod 620 extends or retracts, it pushes the moving block 640 to slide up and down along the connecting rod 630 inside the bearing frame 6, thereby driving the tension adjusting roller 650 to rise and fall.

[0034] Guide roller group 4 is used to guide the transmission path of the unidirectional belt, ensuring its smooth operation and avoiding deviation;

[0035] The film spreading roller group has 5 pairs of unidirectional belts that are spread out to ensure flat transport, providing a good foundation for subsequent winding.

[0036] Furthermore, the system can monitor the tension value of the unidirectional belt in real time through sensors and feed the data back to the controller. The controller automatically adjusts the extension and retraction of the electric push rod 620 according to the preset tension parameters to achieve closed-loop control of tension and ensure the stability of film spreading quality.

[0037] As a preferred technical solution of this utility model, the outer surface of the sliding block 120 is slidably connected to the inside of the sliding groove 110, and the two sides of the lower surface of the bearing block 130 are movably connected to the upper surface of the base 1.

[0038] As a preferred technical solution of this utility model, the outer surface of the tension adjusting roller 650 is provided with an anti-slip rubber layer, and the outer surface of the anti-slip rubber layer is provided with uniformly distributed grooves.

[0039] The anti-slip rubber layer and grooves on the outer surface of the tension adjusting roller 650 can increase the friction with the unidirectional belt and prevent slippage. By adjusting the height of the tension adjusting roller 650, the tension of the unidirectional belt can be changed: when rising, the unidirectional belt is tightened and the tension is increased; when falling, the unidirectional belt is loosened and the tension is reduced, thereby achieving precise control of the tension during the film spreading process.
