Embodiment

[0026] A tensioning device for winding and rolling an ice bag film during processing, comprising two fixed frames 2. One side of the fixed frame 2 is fixedly installed with a shaft rod 3. The surface of the shaft rod 3 is rotatably installed with a rotating arm 4. One side of the rotating arm 4 is fixedly connected with an adjusting disc 5. The surface of the shaft rod 3 is rotatably installed with a connecting arm 6 located outside the rotating arm 4. The connecting arm 6 is adapted to the adjusting disc 5. One end of the inner side of the adjusting disc 5 is fixedly connected with a first spring 7. The end of the first spring 7 away from the adjusting disc 5 is fixedly connected to the connecting arm 6. The side of the fixed frame 2 is provided with uniformly distributed fastening bolts 9 penetrating through. The adjusting disc 5 is fixed to the fixed frame 2 through the fastening bolts 9. A tensioning roller 10 is rotatably installed between the two connecting arms 6.

[0027] The specific usage process is as follows: First, the entire tensioning device is detachably installed on the frame 1. Therefore, according to actual usage requirements, the entire tensioning device can be detached from the frame 1 and can also be installed on other devices for use, such as a slitting device, etc. Moreover, the working height of the tensioning roller 10 can be adjusted according to different adaptation requirements, providing convenience for the user's work. During operation, the rolled film enters from the outside of the mounting frame 20, passes through multiple second guide rollers 21 in sequence, then passes over the tensioning roller 10, and then enters the frame 1. Next, it enters the frame 1 again and passes over multiple first guide rollers 19 in the frame 1 in sequence, and finally is wound onto the winding roller 18. Among them, the tensioning roller 10 can tighten the rolled film. As the rolled film moves, the tensioning roller 10 will swing up and down accordingly. At the same time, the two connecting arms 6 will also swing along with the tensioning roller 10. When the connecting arm 6 swings downward, it will be blocked by the adjusting disc 5 to prevent the tensioning roller 10 and the connecting arm 6 from exceeding the established range during movement, ensuring that the rolled film is normally and smoothly wound. Among them, when the connecting arm 6 swings downward, it will stretch the first spring 7, and then the first spring 7 itself will contract, thereby pulling the connecting arm 6 and the tensioning roller 10 back, so that the tensioning roller 10 can fully adapt to the rolled film, ensuring that the rolled film is normally tightened, providing convenience for the user's work. Among them, the winding roller 18 is used to wind the rolled film together, and the multiple first guide rollers 19 can play a role in tightening the rolled film, preventing the rolled film from sagging loosely, and thus also preventing the rolled film from jamming into the machine, improving the processing quality of the rolled film, and providing convenience for the user's work. After the rolled film is processed, it passes over multiple second guide rollers 21 in the mounting frame 20 in sequence. In this way, the multiple second guide rollers 21 can play a role in guiding and pulling the winding of the rolled film, ensuring that the rolled film can be normally and smoothly wound, providing convenience for the user's work. According to the different usage requirements of different devices, the working height of the tensioning roller 10 can also be adjusted. Specifically as follows, first loosen and remove the fastening bolt 9, and then rotate the adjusting disc 5 counterclockwise. Among them, when the adjusting disc 5 is adjusted and moves, the positioning pin 14 provided on the adjusting disc 5 will also move accordingly. At the same time, under the cooperation of the adjusting disc 5 and the fixed frame 2, the fixed frame 2 will squeeze the positioning pin 14 into the sliding groove 13 and also move it out of the positioning groove 11, and at the same time compress the positioning pin 14. When the next positioning groove 11 aligns with the positioning pin 14, under the action of the second spring 15, the positioning pin 14 will pop out of the inner cavity of the sliding groove 13 and be caught in the positioning groove 11 at the current position, realizing the positioning of the adjusting disc 5. At the same time, a "click click" sound will occur during this process to give a prompt to the user, providing assistance and convenience for the user's adjustment work, and also facilitating the user to fix the adjusting disc 5 on the fixed frame 2 with the fastening bolt 9 later. In this way, the movement stroke of the tensioning roller 10 and the connecting arm 6 is adjusted counterclockwise, and at the same time the working height of the tensioning roller 10 is lowered. On the contrary, the working height of the tensioning roller 10 will be raised.So that the tensioning device can be adaptively installed on different devices to meet the usage requirements of different devices.

[0028] Therefore, a structural design that can adjust the tensioning height is adopted. The height of the tensioning roller in contact with the winding film can be flexibly adjusted according to the actual usage requirements, so that the tensioning device can be adjusted and adapted according to the structures of different devices, ensuring that the winding device can properly tension and adapt to the winding film, ensuring that the winding film is always in a tensioned state, and ensuring that the winding film is smoothly wound, providing convenience for the user's work.

[0029] One side of the fixed frame 2 is provided with a first set of bolt holes 8 that are equally spaced and adapted to the fastening bolts 9. One side of the adjusting disc 5 is provided with a second set of bolt holes 12 that are adapted to the fastening bolts 9.

[0030] Specifically, due to the arrangement of the first set of bolt holes 8 and the second set of bolt holes 12, both the first set of bolt holes 8 and the second set of bolt holes 12 are used for inserting and installing the fastening bolts 9. In this way, the adjusting disc 5 can be fixed on the fixed frame 2 through the fastening bolts 9. During installation, the fastening bolts 9 are passed through the corresponding second set of bolt holes 12 and then inserted into the corresponding first set of bolt holes 8 and finally tightened. It should be noted that several fastening bolts 9 can be installed or one fastening bolt 9 can be installed, and the specific situation can be selected according to the actual situation.

[0031] One side of the adjusting disc 5 is provided with a plurality of sliding grooves 13. A positioning pin 14 is slidably installed in the inner cavity of the sliding groove 13. One side of the fixed frame 2 is provided with a plurality of positioning grooves 11 that are adapted to the positioning pin 14. One end of the positioning pin 14 is fixedly connected to a second spring 15. The end of the second spring 15 away from the positioning pin 14 is fixedly connected to the inner wall of the sliding groove 13.

[0032] Specifically, due to the arrangement of the sliding grooves 13, the positioning pins 14 and the second spring 15, when the adjusting disc 5 is adjusted and moves, the positioning pins 14 provided on the adjusting disc 5 will also move accordingly. At the same time, under the cooperation of the adjusting disc 5 and the fixed frame 2, the fixed frame 2 will squeeze the positioning pins 14 into the sliding grooves 13 and also move them out of the positioning grooves 11, and at the same time compress the positioning pins 14. When the next positioning groove 11 is aligned with the positioning pin 14, the positioning pin 14 will be ejected from the inner cavity of the sliding groove 13 and snapped into the positioning groove 11 at the current position under the action of the second spring 15, realizing the positioning of the adjusting disc 5. At the same time, a "click click" sound will occur during this process to give a prompt to the user, providing assistance and convenience for the user's adjustment work, and also facilitating the user to subsequently fix the adjusting disc 5 on the fixed frame 2 with the fastening bolts 9.

[0033] One side of the adjusting disc 5 is provided with an annular groove 16. A plurality of balls 17 that are adapted to the fixed frame 2 are embedded and movably installed inside the annular groove 16.

[0034] Specifically, due to the provision of the annular groove 16 and the balls 17, a plurality of balls 17 are movably installed in a circular array within the annular groove 16, and all the plurality of balls 17 will roll closely against the surface of the fixing frame 2. In this way, the smoothness of the movement of the adjusting disc 5 can be improved when the adjusting disc 5 is adjusted, providing assistance and convenience for the user's work and use.

[0035] A machine frame 1 is provided between the two fixing frames 2. One end inside the machine frame 1 is rotatably installed with a winding roller 18, and a plurality of first guiding rollers 19 are rotatably installed inside the machine frame 1.

[0036] Specifically, due to the provision of the machine frame 1, the winding roller 18 and the first guiding rollers 19, the winding roller 18 is used to wind the rolled film together, and the plurality of first guiding rollers 19 can play a role in tensioning the rolled film, avoiding the situation that the rolled film sags loosely, and further avoiding the rolled film being blocked inside the machine, improving the processing quality of the rolled film, and providing convenience for the user's work and use.

[0037] A mounting frame 20 is detachably installed on one side of the machine frame 1, and a plurality of second guiding rollers 21 are rotatably installed inside the mounting frame 20.

[0038] Specifically, due to the provision of the mounting frame 20 and the second guiding rollers 21, after the rolled film is processed, it will pass successively through the plurality of second guiding rollers 21 inside the mounting frame 20. In this way, the plurality of second guiding rollers 21 can play a role in guiding and pulling the winding of the rolled film, ensuring that the rolled film can be wound normally and smoothly, and providing convenience for the user's work and use.
