Description

Technical Field

[0001] This utility model relates to the field of film production equipment technology, specifically to a film shaping device. Background Technology

[0002] Plastic film is a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins, used for packaging and as a coating layer. Plastic packaging and plastic packaging products are gaining an increasingly larger market share, especially composite plastic flexible packaging, which is widely used in the food, pharmaceutical, and chemical industries.

[0003] The plastic film produced initially needs to be shaped by a shaping device. First, the film needs to be heated and stretched to make its surface flat. Then it needs to be cooled and shaped. However, the existing shaping device cannot adjust the tension of the film according to actual needs, which can easily affect the shaping effect. Moreover, the height of the shaping device is also not adjustable, which makes it unsuitable for the height of the production machine during assembly line production. There is still room for improvement. Utility Model Content

[0004] The purpose of this invention is to provide a thin film shaping device to solve the problems mentioned in the background art.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: a film shaping device, including an operating table and an adjusting base for controlling the lifting and lowering of the film. A stretching box and a cooling box are respectively provided on the front and rear sides of the operating table. A heating roller, a tensioning roller, and a guide roller are arranged sequentially from front to back inside the stretching box. Openings are provided on both the left and right sides of the stretching box. A first groove and a second groove are provided on the left and right sides of the operating table on the stretching box. A rotatable screw is provided in the first groove, and a movable block is threaded onto the screw. The movable block is slidably connected to the inner wall of the groove. A rotatable screw is vertically provided above the first groove, and a movable block is threaded onto the screw. A connecting frame is provided on the movable block. A guide rod is provided in the second groove, and a sliding block is provided on the guide rod. A guide rod is vertically provided above the sliding block, and a sliding block is provided on the guide rod. A connecting frame is provided on the sliding block. The two ends of the rotating shaft of the tensioning roller are rotatably connected to the connecting frame and the connecting frame.

[0006] Using the above technical solution, the film enters the stretching box and is heated by the heating rollers. Then, it passes through the tensioning rollers for stretching and leveling. After passing through the guide rollers, it exits the stretching box and enters the cooling box for cooling and shaping. When it is necessary to adjust the tension of the film, the position of the tensioning roller can be adjusted: Rotating screw one causes the moving block one to move back and forth, which in turn moves the moving block two and the connecting frame one, thereby moving the shaft of the tensioning roller. Simultaneously, it moves the connecting frame two and the sliding block two, causing the sliding block one to slide on the guide rod one, thus achieving horizontal adjustment of the tensioning roller. Rotating screw two causes the moving block two to rise and fall, which in turn raises and lowers the connecting frame one, thereby raising and lowering the shaft of the tensioning roller. Simultaneously, it raises and lowers the connecting frame two, causing the sliding block two to slide up and down on the guide rod two, thus achieving height adjustment of the tensioning roller.

[0007] As a further optimization of this utility model, the adjusting base includes a pair of support seats, each with a sliding groove. A movable seat that can slide up and down is located within the sliding groove. The upper end of the movable seat is connected to the operating table. A rotatable bidirectional screw is provided on each of the pair of support seats, and a pair of adjusting blocks are threadedly connected to both sides of the bidirectional screw. It also includes a pair of support frames in an inverted V-shape, with the upper end of the support frame rotatably connected to both sides of the bottom of the operating table, and the lower end rotatably connected to the pair of adjusting blocks.

[0008] By adopting the above technical solution, rotating the bidirectional screw drives a pair of adjusting blocks to move closer or further away simultaneously, thereby causing a pair of support frames to open or close. While the pair of support frames are opening or closing, they can raise or lower the operating table, thus achieving the adjustment of the operating table height. This allows the operating table to be matched and adapted to the height of the production machine, improving the degree of production integration.

[0009] As a further optimization of this utility model, the top of the screw is provided with a knob, and the surface of the knob is provided with anti-slip grooves along the circumference.

[0010] As a further optimization of this utility model, a limiting block is provided at the top of the second guide rod.

[0011] Using the above technical solution, the limiting block restricts the sliding block two to prevent it from detaching from the guide rod two.

[0012] As a further optimization of this utility model, one end of the screw passes through the front end of the operating table and is provided with a push rod.

[0013] As a further optimization of this utility model, one end of the bidirectional screw passes through one of the support frames and is provided with a push rod two.

[0014] The beneficial effects of this utility model are as follows: The film enters the stretching box and is heated by the heating roller, then stretches and flattens after passing through the tensioning roller, and then is sent out of the stretching box by the guide roller and enters the cooling box for cooling and shaping. When it is necessary to adjust the tension of the film, the position of the tensioning roller can be adjusted: Rotating screw one causes screw one to move moving block one back and forth, which in turn moves moving block two and connecting frame one, thereby moving the rotating shaft of the tensioning roller. At the same time, it moves connecting frame two and sliding block two, thereby causing sliding block one to slide on guide rod one, thus achieving horizontal adjustment of the tensioning roller; Rotating screw two causes moving block two to rise and fall, which in turn moves connecting frame one, thereby moving the rotating shaft of the tensioning roller to rise and fall, and at the same time, it moves connecting frame two, causing sliding block two to slide up and down on guide rod two, thus achieving height adjustment of the horizontal adjustment of the tensioning roller.

[0020] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0021] See appendix Figure 1-4The present embodiment of this utility model further includes: a film shaping device, comprising an operating table 1 and an adjusting base for controlling the lifting and lowering of the film. Specifically, the adjusting base includes a pair of support seats 5, each with a sliding groove and a movable seat that can slide up and down within the groove. The upper end of the movable seat is connected to the operating table 1. The pair of support seats 5 are provided with a rotatable bidirectional screw 6, and a pair of adjusting blocks 7 are threadedly connected to both sides of the bidirectional screw 6. The device also includes a pair of support frames 8 in an inverted V-shape, with the upper end of the support frame 8 rotatably connected to both sides of the bottom of the operating table 1 and the lower end rotatably connected to the pair of adjusting blocks 7.

[0022] The operating platform 1 has a stretching box 11 and a cooling box 12 on its front and rear sides above it, respectively. The stretching box 11 contains a heating roller 21, a tensioning roller 22, and a guide roller 23 arranged sequentially from front to back. Openings 111 are provided on both the left and right sides of the stretching box 11. The cooling box 12 contains a cooling roller and a cooling fan. The operating platform 1 has a first groove and a second groove on the left and right sides of the stretching box 11. A rotatable screw 31 is provided in the first groove, and a moving block 32 is threaded onto the screw 31. The moving block 32 is engaged with the inner wall of the groove. The rear sliding connection has a rotatable screw 33 vertically mounted above the first groove. A movable block 34 is threaded onto the screw 33. A connecting frame 35 is mounted on the movable block 34. A guide rod 1 is located in the second groove. The guide rod 1 has a sliding block 42 that can slide back and forth. A guide rod 2 is vertically mounted above the sliding block 42. The guide rod 2 has a sliding block 44 that can slide up and down. A connecting frame 45 is mounted on the sliding block 44. The two ends of the rotating shaft of the tension roller 22 are rotatably connected to the connecting frame 35 and the connecting frame 45, respectively.

[0023] Furthermore, the top of the screw 2 33 is provided with a knob 331, the surface of the knob 331 is provided with an anti-slip groove along the circumference, and the top of the guide rod 2 is provided with a limit block 431;

[0024] Furthermore, the end of screw 31 passes through the front end of the operating table 1 and is provided with push rod 1, and the end of the bidirectional screw 6-31 passes through one of the support frames and is provided with push rod 2.

[0025] The principle of this utility model is as follows: The film enters the stretching box 11 and is heated by the heating roller 21. Then it passes through the tensioning roller 22 and is stretched and flattened. Then it is sent out of the stretching box 11 by the guide roller 23 and enters the cooling box 12 for cooling and shaping. When it is necessary to adjust the tension of the film, the position of the tensioning roller 22 can be adjusted: the operating lever 311 rotates the screw 31, the screw drives the moving block 32 to move back and forth, drives the moving block 34 and the connecting frame 35 to move, thereby driving the rotating shaft of the tensioning roller 22 to move. At the same time, it drives the connecting frame 45 and the sliding block 44 to move, thereby driving the sliding block 42 to slide on the guide rod, realizing the horizontal adjustment of the tensioning roller 22.

[0026] The operation knob 331 rotates the screw 33, which drives the moving block 34 to rise and fall, and drives the connecting frame 35 to rise and fall, thereby driving the shaft of the tension roller 22 to rise and fall. At the same time, it drives the connecting frame 45 to rise and fall, so that the sliding block 44 slides up and down on the guide rod 2, realizing the height adjustment of the horizontal adjustment of the tension roller 22. The limit block 431 restricts the sliding block 44 to prevent it from falling off the guide rod 2.

[0027] The operating lever 61 rotates the bidirectional screw 6, causing a pair of adjusting blocks 7 to move closer or further away simultaneously, thereby causing a pair of support frames 8 to open or close. While the pair of support frames 8 are opening or closing, they can raise or lower the operating table 1, thereby adjusting the height of the operating table 1 to match the height of the production machine and improve the degree of production integration.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
