DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 5 As shown: a punching device for antistatic film, comprising a base 1, a back plate 101 is fixed to the rear end of the base 1, a discharge tray 2, a leveling mechanism 3 and a receiving roller 4 are respectively installed on the back plate 101, and a punching block 5 is arranged at the front end through a lifting cylinder 501, and a plurality of punching columns 502 are evenly distributed below the punching block 5; after the film is discharged through the discharge tray 2, it will penetrate into the leveling mechanism 3 for leveling, and then the punching block 5 will perform holes, and the punched film will be guided to the receiving roller 4 through the base 1 and a plurality of guide rollers 6 arranged on the back plate 101, and will be wound up by the receiving roller 4.

[0025] Specifically, the flattening mechanism 3 includes an upper pressing wheel 301 and a lower pressing wheel 302 which are arranged up and down and are synchronously driven with each other. An eccentric adjustment component is also arranged between the upper pressing wheel 301 and the back plate 101, and the eccentric adjustment component can adjust the height of the upper pressing wheel 301 to ensure that it and the lower pressing wheel 302 can press films of different thicknesses.

[0026] Furthermore, the eccentric adjustment assembly includes a fixed shaft 3011 mounted on the back plate 101, and an eccentric shaft 3012 is rotatably sleeved on the outside of the fixed shaft 3011. The upper pressing wheel 301 is also rotatably sleeved on the outside of the eccentric shaft 3012, specifically, the inner center of the eccentric shaft 3012 is concentric with the center of the fixed shaft 3011, and the outer center is concentric with the center of the upper pressing wheel 301.

[0027] Furthermore, a rotating shaft 3021 is also installed on the back plate 101 , and the lower pressing wheel 302 is fixedly sleeved on the outer side of the rotating shaft 3021 .

[0028] Furthermore, the synchronous transmission of the upper pressing wheel 301 and the lower pressing wheel 302 is realized by two identical and meshing gears 303. The gear 303 of the upper pressing wheel 301 is rotatably sleeved on the outside of the eccentric shaft 3012 and is locked and fixed with the upper pressing wheel 301; while the gear 303 of the lower pressing wheel 302 is directly fixedly sleeved on the outside of the rotating shaft 3021, so that it is fixed to the lower pressing wheel 302 and the rotating shaft 3021; ​​when the rotating shaft 3021 drives the lower pressing wheel 302 to rotate, the upper pressing wheel 301 will also rotate together due to the cooperation between the two gears 303, thereby flattening the film.

[0029] Furthermore, the ends of the fixed shaft 3011 and the rotating shaft 3021 are also equipped with a pressure frame 304, which is used to keep the upper pressure wheel 301 and the lower pressure wheel 302 parallel to each other and maintain the stability of the smoothing action. At the same time, bearings can be set at the rotating connection of the component.

[0030] As described above, the height adjustment of the upper pressing wheel 301 is achieved by rotating the eccentric shaft 3012, so an auxiliary device is required to drive the eccentric shaft 3012 to rotate. In this embodiment, the auxiliary device is a handle 3013 that is detachably fixedly connected to the eccentric shaft 3012. Specifically, the handle 3013 is annularly provided with a plurality of slots 30131, and the eccentric shaft 3012 is equipped with a flat key 30121, which can be matched with one of the plurality of slots 30131, so that the handle 3013 and the eccentric shaft 3012 are mutually engaged and fixed; at the same time, the side of the handle 3013 is also in contact with the side wall of the pressure frame 304, so that there is a certain damping feeling when rotating.

[0031] Furthermore, the leveling mechanism 3 and the receiving roller 4 are synchronously driven by the same set of driving components 7 to prevent the film from being pulled and broken during traction.

[0032] Specifically, the driving assembly 7 includes a driving motor 701 mounted on the back plate 101, the motor shaft of which is connected to a transmission wheel I 702, the receiving roller 4 is connected to a transmission wheel II 703, and the rotating shaft 3021 of the lower pressing wheel 302 is connected to the corresponding transmission wheels I 702 and II

[0033] 703, the transmission wheel I 702 and the transmission wheel II 703 are both located on the back of the back plate, the two transmission wheels I 702 are connected by a transmission belt I, and the two transmission wheels II 703 are connected by a transmission belt II.

[0034] like Figure 1 , Figure 2As shown, a frame 102 is also installed on the base 1, and horizontal slide rails (slide rail Ⅰ, slide rail Ⅱ) are respectively arranged on the upper and lower sides of the frame 102, through which the punching block 5 and the lifting cylinder 501 can slide horizontally on the frame 102, so as to approach or move away from the film position. Specifically, two sliders Ⅰ1021 (slide rail ⅠA, slider ⅠB) are slidably arranged on the slide rail Ⅰ located above the frame 102, a horizontal push cylinder 8 is transversely fixed on the frame 102, and its cylinder shaft is connected to the slider ⅠA, and the lifting cylinder 501 is installed on the slider ⅠB through an L-shaped connecting plate 9, and a fine-tuning cylinder 901 is fixed on the L-shaped connecting plate 9, and its cylinder shaft is connected to the cylinder shaft connecting block installed on the above-mentioned slider ⅠA; at the same time, the lifting cylinder 501 itself is also slidably installed on the slide rail Ⅱ located below the frame 102 through the slider Ⅱ1022. When the punching block 5 is driven by the push cylinder 8 to move to the approximate position, it is further driven by the fine-tuning cylinder 901 to move to the accurate position; the punching block 5 is designed to be horizontally slidable in order to leave a certain operating space when the film is manually pulled.

[0035] Furthermore, a punching seat 10 is fixed on the base 1 , and a plurality of through holes matching the punching columns 502 are formed on the punching seat 10 .

[0036] Furthermore, a limiting platform 11 is provided between the leveling mechanism 3 and the punching seat 10 , and the limiting platform 11 is formed with a limiting wall matching the width of the film.

[0037] Furthermore, a high platform 103 composed of several vertical plates is provided at the front end of the base 1, and the punching seat 10 and the limit platform 11 are installed on the top of the high platform 103. The high platform 103 forms a cavity penetrating the front and rear ends. After the film is punched, it can be introduced into the cavity by the guide roller 6 and pass through the opening at the other end of the cavity to the receiving roller 4.

[0038] The action process of this design is roughly as follows: after the rolled film is pulled out from the unloading tray, it is first inserted between the upper and lower pressure wheels to be flattened, and then when passing the position of the punching block, the drive motor will stop briefly and the punching block will punch holes in the film. After the punching process, the drive motor resumes action and continues to pull out the next section of the film, and so on and so forth until the film is completely rolled up.

[0039] The principle of eccentric adjustment is as follows: when the handle is rotated, the handle can drive the eccentric shaft to rotate, thereby controlling the upper pressure wheel to move up or down a certain distance. At this time, the distance between the upper and lower pressure wheels can be adjusted to ensure that film products of different thicknesses can be pressed (this adjustment method is fine-tuning and will not affect the gear transmission).

Unless otherwise defined, the technical terms or scientific terms used in this utility model should be understood by people with ordinary skills in the field. Unless otherwise specified, the words "upper", "lower", "front", "back" and the like are only for the convenience of description and are not limited to a position or a spatial orientation.
