[0006] In a preferred embodiment of this utility model, the fixing component includes a fixing plate, a spring, and a second slot. The fixing plate is disposed at the bottom of the support plate, the second slot is formed at the top of the fixing plate, the punch head is movably connected to the second slot, the first slot is connected to the second slot, the spring is fixedly connected to the bottom of the support plate, and the other end of the spring is fixedly connected to the top of the fixing plate. Several springs are provided and are distributed in a ring at equal intervals. The bottom of the fixing plate is movably connected to the top of the placement plate.
[0007] In a preferred embodiment of this invention, the adjustment mechanism includes a slider and a slide groove. The sliders are fixedly connected to both sides of the bottom of the placement plate, and the slide grooves are opened on both sides of the top of the workbench. The sliders are slidably connected to the slide grooves, and a drive component is provided inside the slide grooves.
[0008] In a preferred embodiment of this invention, the drive assembly includes a support block, a motor, a limiting rod, and a screw. The support block is fixedly connected to the rear side of the top left side of the worktable. The motor is fixedly connected to the top of the support block. The screw is fixedly connected to the output end of the motor. The rear slider is threadedly connected to the screw. The limiting rod is fixedly connected to the inside of the front slide groove. The front slider is sleeved on the surface of the limiting rod.
[0009] As a preferred embodiment of the present invention, the top of the workbench is provided with a first groove, the first slot is connected to the first groove, and the top of the front side of the workbench is provided with a second groove, the inside of which a collection box is movably connected.

[0011] As a preferred embodiment of this utility model, a handle is fixedly connected to the front of the collection box, and the surface of the handle is provided with anti-slip texture.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model solves the problem that existing composite film bag punching equipment often causes the punching position to deviate from the preset coordinates due to the displacement of the packaging bag caused by external force during operation, resulting in a decrease in punching processing accuracy and seriously affecting the quality of finished products.

[0013] 2. This utility model, by setting a fixing component and using the elastic pressing design of the spring and the fixing plate, can adapt to composite film bags of different thicknesses, avoiding deformation of the film bag due to rigid pressing or displacement due to insufficient pressing force. The continuous tension of the spring ensures that the fixing plate always fits stably against the surface of the film bag. When the punching head passes through the second slot through the fixing plate, the fixing plate still maintains the pressing state on the film bag, thus completely solving the problem of film bag displacement.
[0014] 3. This utility model, by setting an adjustment mechanism, allows the placement plate to move laterally along the worktable through the sliding cooperation of the slider and the slide groove, adapting to the punching requirements of composite film bags at different positions.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0020] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.
[0021] Example 1 Reference Figure 1-3This is the first embodiment of the present invention, which provides a punching device for processing composite film bags, including a workbench 1, an L-shaped plate 15 fixedly connected to the rear side of the top of the workbench 1, an electric telescopic rod 2 fixedly connected to the top of the L-shaped plate 15, a support plate 3 fixedly connected to the output end of the electric telescopic rod 2, a punching head 4 fixedly connected to the bottom of the support plate 3, a placement plate 5 provided on the top of the workbench 1, a first slot 6 provided on the top of the placement plate 5, a plurality of first slots 6 provided and distributed in a rectangular equidistant manner, a fixing component 7 provided on the bottom of the support plate 3, and an adjustment mechanism 8 provided on the bottom of the placement plate 5.
[0022] Specifically, compared to existing equipment where low punching accuracy is caused by packaging bag displacement, this device combines mechanized punching with material fixation by driving the punching head 4 with the fixing component 7 via an electric telescopic rod 2. The electric telescopic rod 2 can precisely control the lifting stroke of the punching head 4, avoiding force deviations caused by manual operation. The fixing component 7 can press the composite film bag tightly to prevent it from shifting during punching, ensuring that the punching position is consistent with the preset coordinates. At the same time, multiple sets of first slot holes 6 can adapt to different punching requirements, eliminating the need for frequent mold changes, further improving processing accuracy and efficiency, and ensuring the quality of finished products.
[0023] Furthermore, the workbench 1 provides support for the whole, and the L-shaped plate 15 fixes the installation position of the electric telescopic rod 2. When the electric telescopic rod 2 extends and retracts, it drives the support plate 3 and the bottom punch head 4 to move up and down to realize the punching action. The composite film bag is placed on the placement plate 5. The first slot 6 of the placement plate 5 provides clearance for the punch head 4 to avoid damage to the workbench 1. The fixing component 7 presses the film bag before punching to prevent its displacement. The adjustment mechanism 8 can adjust the position of the placement plate 5 to adapt to the punching requirements of film bags of different sizes and ensure that the punch head 4 is accurately aligned with the preset coordinates.
[0024] Example 2 In the second embodiment of this utility model, the fixing component 7 includes a fixing plate 71, a spring 72, and a second slot 73. The fixing plate 71 is disposed at the bottom of the support plate 3, and the second slot 73 is opened at the top of the fixing plate 71. The punch head 4 is movably connected to the second slot 73. The first slot 6 is connected to the second slot 73. The spring 72 is fixedly connected to the bottom of the support plate 3, and the other end of the spring 72 is fixedly connected to the top of the fixing plate 71. Several springs 72 are provided and are distributed in a ring at equal intervals. The bottom of the fixing plate 71 is movably connected to the top of the placement plate 5.
[0025] Specifically, the fixing component 7, through the elastic clamping design of the spring 72 and the fixing plate 71, can adapt to composite film bags of different thicknesses, avoiding deformation of the film bag due to rigid clamping or displacement due to insufficient clamping force. The continuous tension of the spring 72 ensures that the fixing plate 71 always fits stably against the surface of the film bag. When the punching head 4 passes through the fixing plate 71 through the second slot 73, the fixing plate 71 still maintains the clamping state on the film bag, completely solving the problem of film bag displacement. The second slot 73 is connected to the first slot 6, ensuring that the punching head 4 can complete punching without obstruction, further ensuring the accuracy of the punching position.
[0026] Furthermore, the fixed plate 71 is suspended at the bottom of the support plate 3 and is elastically connected to the support plate 3 through multiple sets of annularly distributed springs 72. When the electric telescopic rod 2 pushes the support plate 3 down, the fixed plate 71 contacts the composite film bag before the punching head 4. As the support plate 3 continues to move down, the springs 72 are compressed and generate a reaction force, causing the fixed plate 71 to tightly press the film bag onto the placement plate 5. The punching head 4 punches the film bag through the second slot 73, and the punching waste is discharged through the first slot 6. After punching is completed, the electric telescopic rod 2 drives the support plate 3 to rise, and the springs 72 reset and pull the fixed plate 71 away from the film bag, completing one punching cycle.
[0027] Example 3 In the third embodiment of this utility model, the adjustment mechanism 8 includes a slider 81 and a slide groove 82. The slider 81 is fixedly connected to both sides of the bottom of the placement plate 5, and the slide groove 82 is opened on both sides of the top of the workbench 1. The slider 81 and the slide groove 82 are slidably connected, and a drive component 83 is provided inside the slide groove 82.
[0028] The drive assembly 83 includes a support block 831, a motor 832, a limiting rod 833, and a screw 834. The support block 831 is fixedly connected to the rear side of the top left side of the worktable 1. The motor 832 is fixedly connected to the top of the support block 831. The screw 834 is fixedly connected to the output end of the motor 832. The rear slider 81 is threadedly connected to the screw 834. The limiting rod 833 is fixedly connected to the inside of the front slide groove 82. The front slider 81 is sleeved on the surface of the limiting rod 833.
[0029] Specifically, the adjustment mechanism 8 allows the placement plate 5 to move laterally along the worktable 1 through the sliding cooperation of the slider 81 and the slide groove 82, adapting to the punching requirements of composite film bags at different positions. Existing equipment often requires manual repositioning of film bags due to the fixed placement plate 5, which can easily lead to secondary displacement. This structure can precisely align the different punching positions of the film bag with the punching head 4 by sliding the placement plate 5, eliminating the need to manually move the film bag, reducing displacement risks, further improving punching accuracy, and reducing the intensity of manual operation. The drive component 83 achieves automated and precise movement of the placement plate 5 through the motor 832 and the screw 834, replacing the manual pushing based on sense positioning. The motor 832 drives the screw 834 to rotate, which can precisely control the movement distance of the placement plate 5, avoiding positional deviations caused by uneven force or visual errors when pushing manually. The limit rod 833 cooperates with the front slider 81 to prevent the placement plate 5 from tilting during movement, ensuring that the film bag always moves in a straight line, further improving the accuracy of the punching coordinates and solving the problems of low efficiency and poor accuracy of manual adjustment in existing equipment.
[0030] Furthermore, the slider 81 at the bottom of the placement plate 5 is embedded in the groove 82 at the top of the worktable 1, forming a sliding guide structure. When the punching position of the film bag needs to be adjusted, the placement plate 5 is pushed, and the slider 81 slides smoothly along the groove 82, driving the film bag to move synchronously. The groove 82 restricts the slider 81 to slide only in a preset direction, preventing the placement plate 5 from shifting and ensuring that the target punching position can still be accurately aligned with the punching head 4 after the film bag moves, providing positional assurance for the accuracy of subsequent punching. The motor 832 is fixed on the support block 831. The output end drives the screw 834 to rotate. The rear slider 81 is threadedly engaged with the screw 834. When the screw 834 rotates, it is converted into linear motion of the slider 81, which drives the placement plate 5 to slide along the slide groove 82. The front slider 81 is sleeved on the surface of the limiting rod 833. The limiting rod 833 restricts the front slider 81 to slide only along the rod body, preventing the placement plate 5 from tilting during movement. By setting the speed and rotation time of the motor 832, the moving distance of the placement plate 5 can be precisely controlled, so that the preset punching position of the film bag is accurately aligned with the punching head 4.
[0031] Working principle: In use, the workbench 1 provides overall support, and the L-shaped plate 15 fixes the installation position of the electric telescopic rod 2. When the electric telescopic rod 2 extends or retracts, it drives the support plate 3 and the bottom punch head 4 to move up and down, realizing the punching action. The composite film bag is placed on the placement plate 5. The first slot 6 of the placement plate 5 provides clearance for the punch head 4 to avoid damage to the workbench 1. When the electric telescopic rod 2 pushes the support plate 3 down, the fixing plate 71 contacts the composite film bag before the punch head 4. As the support plate 3 continues to move down, the spring 72 is compressed and generates a reaction force, so that the fixing plate 71 tightly presses the film bag onto the placement plate 5. The punch head 4 passes through the first slot 6. The second slot 73 punches the film bag, and the punching waste is discharged through the first slot 6. After punching, the electric telescopic rod 2 drives the support plate 3 to rise, and the spring 72 returns to its original position, pulling the fixing plate 71 away from the film bag, completing one punching cycle. When it is necessary to adjust the punching position of the film bag, the motor 832 on the top of the support block 831 is started, and its output end drives the screw 834 to rotate. The rear slider 81 is threadedly engaged with the screw 834. When the screw 834 rotates, it is converted into the linear motion of the slider 81, which drives the placement plate 5 to slide along the slide groove 82. The front slider 81 is sleeved on the surface of the limiting rod 833, and the limiting rod 833 restricts the front side. The slider 81 can only slide along the rod to prevent the placement plate 5 from tilting during movement. By setting the speed and rotation time of the motor 832, the moving distance of the placement plate 5 can be precisely controlled, so that the preset punching position of the film bag is accurately aligned with the punching head 4. Then, when the punching head 4 punches, the waste generated falls into the first groove 9 of the worktable 1 through the second slot 73 and the first slot 6, and then collects in the collection box 11 inside the second groove 10. When the waste accumulates to a certain amount in the collection box 11, the handle 13 is squeezed to move the collection box 11, which can be pulled out along the second groove 10 to dump the waste. After the material is removed, it is pushed back to its original position. At the same time, the anti-slip texture 14 on the surface of the handle 13 increases the coefficient of friction to prevent the hand from sliding relative to the handle 13, ensuring that the collection box 11 is pulled out smoothly. This achieves the effect of fixing the composite film bag with punching. Meanwhile, the damper 12 is fixed between the top of the fixing plate 71 and the bottom of the support plate 3. When the support plate 3 descends, the spring 72 is compressed, and the damper 12 slows down the descent speed of the fixing plate 71 through the internal medium resistance, so that it slowly presses the film bag. After punching is completed, the spring 72 returns to its original position, and the damper 12 also slows down the rising speed of the fixing plate 71 to prevent it from quickly detaching and causing the film bag to be lifted.
[0032] In summary, this utility model, by setting up an electric telescopic rod 2, a support plate 3, a punching head 4, a placement plate 5, and a first slot 6, solves the problem that existing composite film bag punching equipment often experiences displacement of the packaging bag due to external forces during operation, causing the punching position to deviate from the preset coordinates, resulting in decreased punching processing accuracy and seriously affecting the quality of the finished product.
