[0002] The film cutting punch of a film labeling and cutting machine is a tool specifically designed for cutting film labels. It is widely used in packaging, labeling, electronics and other industries, especially in situations where precise cutting of film materials is required. The main function of the film cutting punch is to precisely cut the film material into the required shape and size by applying cutting force to the film.

[0003] When in use, existing die-cutting punches are usually connected to the hydraulic cylinders on film labeling and cutting machines, so that the hydraulic cylinders can drive the die-cutting punches to move up and down to cut the film.

[0004] However, existing die-cutting punches generally lack efficient and convenient quick-installation components during installation and replacement. Specifically, the installation process usually requires operators to manually perform a series of fixing and adjustment operations on the punch. This operation often involves relatively complex steps such as bolt fixing, and each installation or replacement takes a long time to complete. Due to the lack of a dedicated quick-installation structure, the entire installation process is too cumbersome and is prone to inaccurate installation or loosening of the punch due to improper operation. This cumbersome installation method not only greatly increases the downtime of the production line, but also requires workers to exert more labor intensity. Utility Model Content

Detailed Implementation

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] Example 1, please refer to Figure 1-6This utility model provides a technical solution: a film cutting punch for a film labeling film cutting machine, including a hydraulic cylinder 1, a connecting plate 101 fixedly installed at the bottom of the hydraulic cylinder 1, and a punch plate 102 movably connected to the bottom of the connecting plate 101. Positioning posts 115 are fixedly installed around the top of the punch plate 102, and multiple punch bodies 113 are provided at the bottom of the punch plate 102; four positioning grooves 114 are all opened at the bottom of the connecting plate 101; wherein the four positioning posts 115 are matched with the positioning grooves 114; two rotating rods 103 are movably embedded inside the punch plate 102, and connecting parts 104 are fixedly sleeved on the outer surfaces of the two rotating rods 103; wherein the two rotating rods 103 can drive the connecting parts 104 to perform a flipping motion; two locking blocks 105 are slidably connected to the top of the connecting plate 101, and movable rods 106 are movably connected inside the two locking blocks 105; wherein the two locking blocks 105 can... The connecting plate 101 slides left and right on its top. The outer surfaces of the two connecting parts 104 on opposite sides are movably embedded in the inside of the locking block 105. The other ends of the two movable rods 106 are movably connected to sliders 107. The top of the connecting plate 101 has a groove 109, and the bottom outer surface of the slider 107 is slidably connected to the inner surface of the groove 109. The slider 107 can slide on the top of the connecting plate 101 through the cooperation of the groove 109. A screw 108 is movably embedded inside the 01, and the screw 108 is threadedly connected to the inside of the slider 107. The screw 108 is located inside the slide groove 109, and a crank 110 is fixedly installed on the rear side of the screw 108. The outer surface of the crank 110 is provided with multiple limiting teeth 111. A limiting post 112 is movably embedded in the rear side of the connecting plate 101. The right side of the limiting post 112 is provided with teeth, and the limiting post 112 meshes with the multiple limiting teeth 111.

[0045] In this embodiment, the operator can first connect the connecting plate 101 to the bottom of the hydraulic cylinder 1 on the film labeling and cutting machine by welding or other methods. Then, the operator picks up the punch plate 102 and aligns its top with the bottom of the connecting plate 101, so that the positioning post 115 is embedded in the positioning groove 114. After that, the operator pushes the connecting piece 104 upward, so that it can be flipped upward by the rotating rod 103, thereby allowing the connecting piece 104 to be flipped to the top of the connecting plate 101. Then, the operator can turn the crank handle 110 to drive the screw 108. When the screw 108 rotates, it can drive the slider 107, so that it can slide backward through the slide groove 109. When the slider 107 slides, it can pull one end of the movable rod 106, so that it can be flipped relative to each other. When the movable rod 106 is flipped, it can pull the two locking blocks 105 to slide relative to each other, thereby enabling the locking blocks 105 to be locked. Five plates are set on the outer surface of the connector 104 to connect the punch body 113 to the hydraulic cylinder 1 via the punch plate 102 and the connecting plate 101. After the punch plate 102 is fixed, the operator can insert the limiting post 112 into the inside of the connecting plate 101 so that the limiting post 112 can lock the limiting tooth 111 on the crank handle 110 to lock the crank handle 110. The structure of the connector 104 and the locking block 105 not only makes the installation and fixing process of the punch body 113 simpler and faster, but also allows the operator to operate step by step without complicated manual adjustment or precise docking, thus greatly shortening the time required for installing and replacing the punch body 113. At the same time, the design of the limiting post 112 and the limiting tooth 111 can effectively prevent the crank handle 110 from being accidentally loosened or misoperated during operation, ensuring the safety of the equipment during operation.

[0046] Example 2, as Figure 1-6 As shown, telescopic rods 2 are fixedly installed around the bottom of the punch plate 102, and return springs 201 are fixedly installed around the bottom of the punch plate 102; wherein, the four return springs 201 are movably sleeved on the outer surface of the telescopic rods 2, and pressure plates 202 are fixedly installed at the bottom of the four telescopic rods 2 and the four return springs 201, and soft pads 203 are provided at the bottom of the pressure plates 202.

[0047] In this embodiment, the operator can first activate the hydraulic cylinder 1 via its drive system. When the cylinder extends, it can drive the punch plate 102 to descend via the connecting plate 101. As the punch plate 102 descends, it can drive the punch body 113 and the pressure plate 202 to descend synchronously. Since the pressure plate 202 is lower than the punch body 113, during the descent, the pressure plate 202 will cause the soft pad 203 to adhere to the top of the film first. At the same time, the pressure plate 202 can compress the telescopic rod 2 and the return spring 201 to retract, thereby fixing the film during the film cutting process. The structure of the telescopic rod 2 and the pressure plate 202 not only fixes the film to ensure that it does not slide or shift during the cutting process, thus improving the stability of the film cutting and reducing the cutting error caused by film displacement, but also prevents the pressure plate 202 from directly contacting the outer surface of the film when fixing it, thus avoiding wear on the film.

[0048] Working principle: In use, the operator first connects the connecting plate 101 to the bottom of the hydraulic cylinder 1 on the film labeling and cutting machine by welding or other methods. Then, the punch plate 102 is lifted, and its top is aligned with the bottom of the connecting plate 101, so that the positioning post 115 is embedded in the positioning groove 114. Then, the connecting piece 104 is pushed upward, so that it can be flipped upward by the rotating rod 103, thereby allowing the connecting piece 104 to flip to the top of the connecting plate 101. Then, the operator can turn the crank handle 110 to drive the screw 108. When the screw 108 rotates, it can drive the slider 107, which can slide backward through the slide groove 109. When the slider 107 slides, it can pull one end of the movable rod 106, so that it can be flipped relative to each other. When the movable rod 106 flips, it can pull the two locking blocks 105 to slide relative to each other, thereby locking the blocks. 105 is fitted onto the outer surface of the connector 104 to connect the punch body 113 to the hydraulic cylinder 1 via the punch plate 102 and the connecting plate 101. After the punch plate 102 is fixed, the operator can insert the limiting post 112 into the inside of the connecting plate 101 so that the limiting post 112 can lock the limiting teeth 111 on the crank handle 110 to lock the crank handle 110. The structure of the connector 104 and the locking block 105 not only makes the installation and fixing process of the punch body 113 simpler and faster, but also allows the operator to operate step by step without complicated manual adjustment or precise docking, thus greatly shortening the time required for installing and replacing the punch body 113. At the same time, the design of the limiting post 112 and the limiting teeth 111 can effectively prevent the crank handle 110 from accidentally loosening or being misoperated during operation, ensuring the safety of the equipment during operation.

[0049] In use, the operator can first activate the hydraulic cylinder 1 via its drive system. During extension, the cylinder 1 extends, causing the punch plate 102 to descend via the connecting plate 101. As the punch plate 102 descends, it simultaneously lowers the punch body 113 and the pressure plate 202. Because the pressure plate 202 is lower than the punch body 113, during descent, the pressure plate 202 will cause the soft pad 203 to adhere to the top of the film first. Simultaneously, the pressure plate 202 can compress the telescopic rod 2 and the return spring 201 to retract, thus fixing the film during the cutting process. The structure of the telescopic rod 2 and the pressure plate 202 not only fixes the film, ensuring it doesn't slip or shift during cutting, improving stability and reducing cutting errors caused by film displacement, but also prevents the pressure plate 202 from directly contacting the outer surface of the film, thus avoiding wear.

[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
