Description

Technical Field

[0001] This utility model relates to the field of encapsulation film processing equipment technology, and in particular to a mechanism for adjusting the position of the pressure plate of an encapsulation film punching machine. Background Technology

[0002] Encapsulation films are widely used in power batteries, energy storage batteries, solid-state batteries, photovoltaic cells, and electronic products. They prevent external impurities, moisture, and oxygen from penetrating the product, thus avoiding corrosion or damage and effectively extending its lifespan and improving its stability. Encapsulation films are typically produced using a stamping machine, and the production process is as follows:

[0003] A punching cutter for cutting the contour of the encapsulation film is fixed on the worktable of a punching machine. The encapsulation film material is then placed on the punching cutter. The worktable is driven to move the punching cutter and the encapsulation film material below the pressure plate of the punching machine. A hydraulic cylinder then drives the pressure plate downwards, pressing the encapsulation film material onto the punching cutter, where it is cut to form the finished encapsulation film. During this punching process, the punching cutter creates cuts on the pressure plate. When these cuts are deep, the cutter may fail to cut through the encapsulation film. Therefore, after a period of punching, the position of the pressure plate needs to be adjusted to prevent the cutter from acting on the same position on the pressure plate for an extended period. However, in existing punching machines, the adjustment of the pressure plate position requires manual operation, which is inconvenient and inefficient. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a pressure plate fine adjustment mechanism for a packaging film punching machine, so as to solve the technical problems that the pressure plate position of the existing packaging film punching machine needs to be manually adjusted, which is inconvenient and inefficient.

[0005] This utility model relates to a fine-tuning mechanism for the pressure plate of a film punching machine. It includes a lifting seat driven by a hydraulic cylinder of the punching machine and a pressure plate located at the bottom of the lifting seat. It also includes a support pin and a crossbar. The support pin is vertically fixed to the front and rear sides of the lifting seat. The crossbar has several slotted holes, the length of which is parallel to the pressure plate. The slotted holes pass through the support pin, and the support pin slides into the slotted holes. The edge of the pressure plate is fixedly connected to the crossbar.

[0006] The fine-tuning mechanism of the pressure plate of the encapsulation film punching machine also includes a left shaft seat and a right shaft seat set on the front or rear side of the lifting seat, a left vertical shaft rotatably connected to the left shaft seat, a right vertical shaft rotatably connected to the right shaft seat, and a reducer set on the top surface of the lifting seat. The power output shaft of the left vertical shaft, the right vertical shaft and the reducer are connected by a transmission mechanism composed of a sprocket and a chain or a transmission mechanism composed of a synchronous pulley and a synchronous belt. The lower ends of the left vertical shaft and the right vertical shaft are respectively provided with cranks, and the ends of the cranks are provided with vertical pins that rotatably cooperate with the crossbar.

[0007] Furthermore, a slotted block is connected to the crossbar by screws, and the edge of the pressure plate is engaged with the crossbar by the slotted block.

[0008] Furthermore, a protective cover for shielding the transmission mechanism is also connected to the top surface of the lifting seat.

[0009] The beneficial effects of this utility model are:

[0010] The micro-adjustment mechanism of the pressure plate of the encapsulation film punching machine can adjust the position of the pressure plate through a reducer. The adjustment is simple and convenient, saving time and effort, and is highly efficient. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] like Figures 1-3 As shown, in this embodiment, the pressure plate fine-tuning mechanism of the encapsulation film punching machine includes a lifting seat 2 driven to rise and fall by the hydraulic cylinder 1 of the punching machine and a pressure plate 3 located at the bottom of the lifting seat, as well as a support pin 4 and a crossbar 5; the support pin is vertically fixed on the front and rear sides of the lifting seat; the crossbar is provided with a plurality of strip holes 6, the length direction of the strip holes is parallel to the pressure plate, the strip holes are sleeved on the support pin, and the support pin slides in cooperation with the strip holes; the edge of the pressure plate is fixedly connected to the crossbar.

[0016] The fine-tuning mechanism of the pressure plate of the encapsulation film punching machine also includes a left shaft seat 7 and a right shaft seat 8 disposed on the front side of the lifting seat (in different embodiments, the left shaft seat 7 and the right shaft seat 8 may also be disposed on the rear side of the lifting seat), a left vertical shaft 9 rotatably connected to the left shaft seat, a right vertical shaft 10 rotatably connected to the right shaft seat, and a reducer 11 disposed on the top surface of the lifting seat. The power output shafts of the left vertical shaft, the right vertical shaft and the reducer are connected by a transmission mechanism composed of a synchronous pulley 12 and a synchronous belt 13. In different embodiments, the transmission mechanism may also be a transmission mechanism composed of a sprocket and a chain.

[0017] The lower ends of the left and right vertical shafts are respectively provided with cranks 14, and the ends of the cranks are provided with vertical pins 15 that are rotatably engaged with the crossbar.

[0018] After the encapsulation film punching machine has been working for a period of time, deep cuts will appear on the part of the pressure plate 3 that is directly opposite the die-cutting blade. At this time, the position of the pressure plate can be changed by controlling the reducer 11, thereby offsetting the cuts on the pressure plate from the die-cutting blade. When the reducer is working, the power output shaft of the reducer 11 rotates, and the power output shaft drives the left vertical shaft 9 and the right vertical shaft 10 to rotate synchronously through the transmission mechanism. The left vertical shaft 9 and the right vertical shaft 10 respectively drive the lower crank 14 to rotate, and the crank 14 then drives the horizontal bar 5 to move through the vertical pin 15. The pressure plate 3 connected to the horizontal bar 5 will move synchronously, thereby realizing the adjustment of the pressure plate position. The adjustment is time-saving, labor-saving, and highly efficient.

[0019] As an improvement to the above embodiment, a retaining block 17 is connected to the crossbar by screws 16, and the edge of the pressure plate 3 is engaged with the crossbar by the retaining block. This improvement connects the pressure plate 3 via the retaining block 17, making the pressure plate easy to assemble and disassemble.

[0020] As an improvement to the above embodiment, a protective cover 18 for shielding the transmission mechanism is also connected to the top surface of the lifting seat. The protective cover can prevent foreign objects from entering the transmission mechanism and improve the safety of the transmission mechanism.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
