Description

Technical Field

[0001] This utility model belongs to the field of membrane material processing technology, and specifically relates to a tension adjustment device for membrane material processing. Background Technology

[0002] During membrane material processing, tensioning is required. To better meet the tension adjustment needs, a tension adjustment structure is necessary. While existing tension adjustment devices for membrane material processing can meet the basic requirements for tension adjustment, the tension roller is typically connected to the adjustment structure via bolts. This necessitates users manually removing and reassembling the bolts using tools during disassembly and maintenance. This is not only cumbersome but also reduces maintenance efficiency, consequently impacting the overall efficiency of membrane material processing.

[0003] For example, utility model patent CN220664315U discloses a novel winding device for membrane material processing. In the technical solution of this patent document, the tensioning mechanism includes threaded rods installed in two sets of mounting slots, and the upper ends of both sets of threaded rods are fixedly connected to auxiliary wheels through the mounting frame. The two sets of auxiliary wheels are connected by a second synchronous belt. One end of one set of threaded rods is fixedly connected to a first rotating wheel through the auxiliary wheel. The lower ends of both sets of threaded rods are threadedly connected to movable blocks, and the upper surfaces of both sets of movable blocks are provided with slots for the tensioning roller to be embedded. The upper surfaces of both sets of movable blocks are fixedly connected to limit blocks by positioning screws. The movable blocks are slidably connected to the mounting slots. Since the screws need to be disassembled and reassembled with tools before the tensioning roller can be disassembled and reassembled, the operation is very troublesome and will cause great inconvenience to users. Therefore, it cannot fully meet the needs of users. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a tension adjustment device for membrane material processing. This device not only meets the basic requirements for tension adjustment during membrane material processing but also allows users to quickly and easily assemble and disassemble the tension roller, thereby more fully meeting people's usage needs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a tension adjustment device for membrane material processing, including a mounting frame set on a membrane material processing table, a mounting groove vertically slidably provided on the mounting frame, a bidirectional screw rotatably provided between the two ends of the mounting groove, a mounting block slidably connected to the mounting groove on both sides of the bidirectional screw, a mounting plate provided on the mounting block, a plug-in cylinder rotatably provided on the mounting plate, a plug-in block for plugging into the plug-in cylinder provided on the side end of the tension roller, and the plug-in hole on the inner side of the plug-in cylinder and the vertical cross section of the plug-in block are both non-circular.

[0006] As a further improvement of this utility model, a handle for rotating the bidirectional screw is provided at the side end of the mounting groove. The handle facilitates manual rotation of the bidirectional screw by the user.

[0007] As a further improvement of this utility model, a telescopic push rod is vertically provided on the top of the mounting bracket, the output shaft of the telescopic push rod is connected to the top of the mounting groove, and a guide slot located at the side end of the telescopic push rod is also provided on the top of the mounting bracket, and a guide plate that is inserted into the guide slot is provided on the top of the mounting groove.

[0008] As a further improvement of this utility model, a hand-tightening locking bolt is screwed onto the guide slot, which can abut against the outer wall of the guide plate to fix the connection between the guide slot and the guide plate.

[0009] As a further improvement of this utility model, an L-shaped connecting frame is also provided on the side end of the mounting groove, and a connecting sleeve is provided on the mounting plate that is slidably connected to the horizontal part of the connecting frame. A hand-tightening limiting bolt is provided on the connecting sleeve that can abut against the outer side wall of the connecting frame to fix the connection between the connecting sleeve and the connecting frame.

[0010] As a further improvement of this utility model, the insertion hole on the inner side of the insertion tube and the vertical cross section of the insertion block are both rectangular.

[0011] As a further improvement of this utility model, a fixing plate is provided at the bottom side of the mounting frame, and fixing bolts are provided on the fixing plate for screwing onto the film processing table. The fixing plate at the bottom of the mounting frame is connected to the film processing table through fixing bolts, ensuring that the entire device will not shift or shake during operation, thereby improving processing accuracy and safety.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Firstly, the design of synchronously sliding the mounting blocks, mounting plates, and plug-in cylinders on both sides via a bidirectional screw allows for flexible and convenient connection or disconnection of the plug-in blocks and tension rollers, enabling users to quickly and easily disassemble, install, and maintain the tension rollers.

[0014] Secondly, by extending and retracting the telescopic push rod and engaging the guide slot and guide plate, the vertical height of the mounting groove and tension roller can be easily and stably adjusted, thereby achieving the adjustment of the tension.

[0015] Third, the hand-tightening locking bolts on the guide slot can fix the connection between the guide slot and the guide plate, preventing the installation slot and tension roller from shifting vertically on their own after the height adjustment of the installation slot and tension roller is completed.

[0016] Fourth, the sliding connection structure of the L-shaped connecting frame and the connecting sleeve, combined with the hand-tightened limiting bolts, allows the mounting plate to be flexibly adjusted within a certain range and fixed after adjustment, thus improving the adaptability and stability of the device.

Detailed Implementation

[0023] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0024] like Figure 1 , 2 As shown in Figure 4, a tension adjustment device for membrane material processing includes a mounting frame 101 mounted on a membrane material processing table. A mounting groove 102 is vertically slidably disposed on the mounting frame 101. A bidirectional screw 103 is rotatably disposed between the two ends of the mounting groove 102. Mounting blocks 104, slidably connected to the mounting groove 102, are screwed to both sides of the bidirectional screw 103. A mounting plate 105 is disposed on the mounting block 104. A connector cylinder 106 is rotatably disposed on the mounting plate 105 via a bearing 111. A connector block 107 is disposed on the side end of the tension roller 100, which inserts into the connector cylinder 106. The insertion hole 112 inside the connector cylinder 106 and the vertical cross-section of the connector block 107 are both non-circular. The insertion hole 112 inside the connector cylinder 106 and the vertical cross-section of the connector block 107 are both rectangular.

[0025] like Figure 2 As shown, a handle 108 for rotating the bidirectional screw 103 is provided on the side end of the mounting slot 102. The handle 108 is designed to allow the user to manually rotate the bidirectional screw 103.

[0026] like Figure 1 As shown, a telescopic push rod 201 is vertically arranged on the top of the mounting bracket 101. The output shaft of the telescopic push rod 201 is connected to the top of the mounting groove 102. A guide slot 202 located on the side of the telescopic push rod 201 is also provided on the top of the mounting bracket 101. A guide plate 203 that is inserted into the guide slot 202 is provided on the top of the mounting groove 102.

[0027] like Figure 1 As shown, a hand-tightening locking bolt 204 is also screwed onto the guide slot 202, which can abut against the outer wall of the guide insert 203 to fix the connection between the guide slot 202 and the guide insert 203.

[0028] like Figure 1 , 2 As shown in Figure 3, an L-shaped connecting frame 301 is also provided on the side end of the mounting groove 102. A connecting sleeve 302 is provided on the mounting plate 105 and is slidably connected to the horizontal part of the connecting frame 301. A hand-tightening limiting bolt 303 is provided on the connecting sleeve 302, which can abut against the outer wall of the connecting frame 301 to fix the connection between the connecting sleeve 302 and the connecting frame 301.

[0029] After the device is installed on the film processing table, the insertion block 107 on one side can be inserted and fixed with the corresponding insertion cylinder 106 to achieve initial fixation of the tension roller 100. Then, by turning the double screw 103 with the handle 108, under the sliding cooperation of the connecting sleeve 302 and the connecting frame 301, the mounting blocks 104 and insertion cylinders 106 on both sides move towards the center until the insertion block 107 on the other side is inserted and fixed with the corresponding insertion cylinder 106, thereby achieving stable insertion and fixation of the tension roller 100. Since the insertion hole 112 on the inner side of the insertion cylinder 106 and the vertical cross section of the insertion block 107 are both non-circular (e.g., rectangular), this design can prevent the tension roller 100 from rotating relative to each other during operation, thereby ensuring stable rotational support for the tension roller 100. Next, tighten the hand-tightening limit bolt 303 to fix the connection between the connecting sleeve 302 and the connecting frame 301, so as to more stably prevent the mounting block 104, mounting plate 105, and plug-in cylinder 106 from shifting on their own and affecting the fixing stability of the tension roller 100.

[0030] The telescopic push rod 201 can then be raised and lowered. By connecting the guide plate 203 and the guide slot 202, the vertical height of the mounting groove 102 and the tension roller 100 can be adjusted. Then, tighten the hand-tightening bolt 204 to reinforce the connection between the guide slot 202 and the guide plate 203, so as to better prevent the mounting groove 102 and the tension roller 100 from sliding down automatically, thereby avoiding affecting the tensioning effect of the adjusted tension roller 100.

[0031] When the tension roller 100 needs to be disassembled, simply loosen the hand-tightening limit bolt 303 to release the fixation of the connection between the connecting sleeve 302 and the connecting frame 301. Then, the bidirectional screw 103 can be turned and adjusted by turning the handle 108 to make the mounting blocks 104, mounting plates 105 and plug-in cylinders 106 on both sides move away from each other, thereby releasing the insertion and support of the tension roller 100 and the plug-in block 107. Then the tension roller 100 can be removed for maintenance.

[0032] According to another embodiment of the present invention, such as Figure 1 As shown, a fixing plate 109 is provided at the bottom side of the mounting bracket 101, and a fixing bolt 110 is provided on the fixing plate 109 for screwing onto the film processing table. The mounting bracket 101 can be flexibly fixed to the film processing table simply by passing the fixing bolt 110 through the fixing plate 109 and screwing it into the threaded fixing hole on the film processing table.

[0033] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
