Technical Field

[0001] This utility model relates to the field of stretch film technology, specifically to a composite biodegradable film synthesis device. Background Technology

[0002] Stretch film, also known as stretch wrap or stretch wrap film, is a thin film used for wrapping and packaging goods. It has advantages such as high toughness, high elasticity, tear resistance, high adhesion, thinness, cold resistance, heat resistance, pressure resistance, dustproof, waterproof, and anti-theft properties. Using stretch film can save packaging costs such as packaging materials, labor, and time. It is widely used in the bundling and packaging of industries such as automotive parts, electronics, building materials and chemicals, glass and ceramics, hardware and machinery, logistics and express delivery, e-commerce, wire and cable, paper and printing, beverage and food, can making, textiles, and daily necessities.

[0003] The prior art patent document CN214927928U provides a composite biodegradable thin wrapping film synthesis device. The device uses a motor to drive the traction roller to move up and down, and adjusts the position of the traction roller to adjust the tightness of the wrapping film on the traction roller, so that the wrapping film fits the pressure roller and traction roller better, thereby improving the synthesis efficiency. It is equipped with a preheating device, which blows hot air onto the wrapping film before it enters the pressure roller for pressing, so as to preheat the wrapping film and facilitate better synthesis of multilayer wrapping film.

[0004] While the existing technology described above can synthesize stretch film, it requires cutting after the film is rolled up. This is usually done manually with a cutting knife, which is laborious and cumbersome. The device cannot cut the stretch film effectively and does not meet people's needs. Therefore, we need a composite biodegradable film synthesis device. Utility Model Content

[0024] like Figure 1-4As shown, a composite biodegradable film synthesis device includes a base 1, a fixing frame 2 fixedly connected to the top of the base 1, a mounting base 3 fixedly connected to the top of the base 1, a support frame 4 fixedly connected to the top of the base 1, and a mounting frame 5 fixedly connected to the top of the base 1.

The cutting assembly 6 includes a slide groove 601. A reduction motor 602 is mounted on the top of the mounting base 3, and the output shaft of the reduction motor 602 is fixedly connected to a lead screw 603 via a coupling. The outer wall of the lead screw 603 is threaded with... The movable block 604 is fixedly connected to the outer wall of the movable block 604, and the inner wall of the blade holder 605 is detachably connected to the cutting blade 606; the winding assembly 7 includes a fixed bearing 701, a fixed motor 702 is installed on the outer wall of the fixed frame 2, and the output shaft of the fixed motor 702 is fixedly connected to a rotating rod 703 through a coupling. A baffle 704 is fixedly connected to the outer wall of the rotating rod 703, and an external thread 705 is provided on the outer wall of the rotating rod 703. A winding drum 706 is slidably connected to the outer wall of the rotating rod 703, and a threaded cap 707 is threadedly connected to one end of the rotating rod 703.

[0025] Through the above technical solution, the reduction motor 602 drives the lead screw 603 to rotate, causing the moving block 604 to move the knife holder 605, which in turn moves the cutting blade 606, thus achieving the cutting of the stretch film. This improves cutting efficiency, eliminates the need for manual operation, and saves labor, meeting people's needs. The fixed motor 702 drives the rotating rod 703 to rotate, thereby causing the winding drum 706 to rotate and wind up the stretch film. After winding is completed, the winding drum 706 can be easily removed by unscrewing the threaded cap 707, facilitating the replacement of a new winding drum 706 for continued winding operations. The operation is simple and convenient.

[0026] Specifically, a first electric push rod 8 is fixedly connected to the top of the support frame 4, and a first connecting frame 9 is fixedly connected to one end of the first electric push rod 8. A hot pressure roller 10 is rotatably connected to the inner wall of the first connecting frame 9. A second electric push rod 11 is fixedly connected to the inner wall of the mounting frame 5, and a second connecting frame 12 is fixedly connected to one end of the second electric push rod 11. A traction roller 13 is rotatably connected to the inner wall of the second connecting frame 12.

[0027] Through the above technical solution, the operation of the first electric push rod 8 drives the first connecting frame 9 to move, and the first connecting frame 9 drives the hot pressure roller 10 to move, which can adjust the distance between the upper and lower hot pressure rollers 10; the operation of the second electric push rod 11 drives the second connecting frame 12 to move, and the movement of the second connecting frame 12 drives the traction roller 13 to move, which can adjust the tightness of the wrapping film; a preheating device is provided between the support frame 4 and the mounting frame 5 on the base 1, which can blow hot air onto the wrapping film to preheat the wrapping film, which is the existing technology; a sliding groove 601 is opened in the mounting base 3, and a fixed bearing 701 is fixed on the inner wall of the fixed frame 2; a controller is provided on the support frame 4.

[0028] Specifically, the geared motor 602 forms a moving structure with the moving block 604 via the lead screw 603, and one end of the lead screw 603 is threaded through the moving block 604.

[0029] The above technical solution enhances the connection between the geared motor 602, the lead screw 603, and the moving block 604. One end of the lead screw 603 is equipped with a bearing, which is fixed in the mounting base 3. When the lead screw 603 rotates, it rotates more stably within the bearing.

[0030] Specifically, the inner wall shape and size of the slide 601 match the outer wall shape and size of the moving block 604, and the inner wall of the slide 601 fits into the outer wall of the moving block 604.

[0031] The above technical solution enhances the connection between the slide 601 and the moving block 604, making the movement of the moving block 604 within the slide 601 more stable when the moving block 604 moves.

[0032] Specifically, the fixed frame 2 forms a rotating structure with the fixed motor 702 and the rotating rod 703, and one end of the fixed motor 702 passes through the fixed frame 2 and is connected to the rotating rod 703.

[0033] The above technical solution enhances the connection between the fixed frame 2, the fixed motor 702, and the rotating rod 703. When the fixed motor 702 is working, it can drive the rotating rod 703 to rotate effectively. One end of the rotating rod 703 passes through the fixed bearing 701, making the rotation of the rotating rod 703 within the fixed bearing 701 more stable.

[0034] Specifically, the outer wall shape and size of the rotating rod 703 match the inner wall shape and size of the take-up drum 706, and one end of the rotating rod 703 passes through the take-up drum 706, with the outer wall of the rotating rod 703 fitting against the inner wall of the take-up drum 706.

[0035] The above technical solution facilitates the installation of the take-up drum 706 onto the rotating rod 703. When the take-up drum 706 is full of winding film, it can be disassembled and replaced with a new take-up drum 706.

[0036] Specifically, the rotating rod 703 forms a threaded structure with the threaded cap 707 via the external thread 705, and one end of the rotating rod 703 is threaded through the threaded cap 707.

[0037] Through the above technical solution, the thread on the external thread 705 matches the thread inside the thread cap 707, making it easy for the thread cap 707 to be threaded onto the external thread 705 of the rotating rod 703.

[0038] In use, first connect an external power supply to the device. The external power supply provides power to the device. The stretch film passes over the traction roller 13, passes between the upper and lower hot press rollers 10, and is wound onto the take-up drum 706. During operation, the fixed motor 702 drives the rotating rod 703 to rotate, which in turn drives the take-up drum 706 to rotate, winding up the finished stretch film. The second electric push rod 11 drives the second connecting frame 12 to move, which in turn drives the traction roller 13 to move, thereby adjusting the height of the traction roller 13. This facilitates adjusting the tightness of the stretch film on the traction roller 13, making the stretch film fit the hot press rollers 10 and traction rollers 13 better, improving the synthesis efficiency. Before the stretch film enters the hot press rollers 10 for pressing, the preheating device blows hot air onto the stretch film to preheat it. The first electric push rod 8 drives the first connecting frame 9 to move, which in turn drives the hot press rollers 10 to move, adjusting the upper and lower hot press rollers 10. The gap between the 0s is such that the multi-layer stretch film is pressed together by the upper and lower hot press rollers 10. The heating device in the hot press rollers 10 can generate heat to hot press the multi-layer stretch film. After the stretch film is wound up, the geared motor 602 works to drive the lead screw 603 to rotate, causing the moving block 604 to move down. The moving block 604 drives the knife holder 605 to move down, and the knife holder 605 drives the cutting blade 606 to move down to cut the stretch film. The operator removes the thread cap 707 and removes the wound take-up drum 706 from the rotating rod 700. Remove the 03 and replace it with a new take-up drum 706. Slide the new take-up drum 706 onto the rotating rod 703. The outer wall of the take-up drum 706 should be in contact with the baffle 704. Thread the threaded cap 707 onto the external thread 705 of the rotating rod 703. By rotating the threaded cap 707, the threaded cap 707 will press the take-up drum 706 against the rotating rod, making it easier to rewind. This completes the entire operation. Any content not described in detail in this manual is prior art known to those skilled in the art.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
