[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figures 1-4 As shown, a perforated plate sealing machine includes a frame 1 and a roller conveyor 2. The roller conveyor 2 is disposed on the top of the frame 1. A sealing assembly 3 is fixedly installed on the top of the frame 1. A cutting assembly 4 is disposed on the top of the frame 1. The cutting assembly 4 includes a base plate 41 and a top plate 42 slidably connected inside the frame 1. The top plate 42 is disposed above the base plate 41. Four cylinders 43 arranged in a rectangular array are disposed between the base plate 41 and the top plate 42. A first cutter 44 is fixedly connected to the top of the base plate 41. A second cutter 45 corresponding to the first cutter 44 is fixedly connected to the bottom of the top plate 42.

[0022] According to the above structure, during use, the perforated plates are placed sequentially on the roller conveyor 2. The roller conveyor 2 drives the perforated plates to move forward. After the perforated plates are sealed by the sealing assembly 3, the perforated plates continue to move backward. When the gap between the two perforated plates is conveyed to the space between the first cutter 44 and the second cutter 45, the substrate 41 moves forward synchronously with the perforated plates. At the same time, the two cylinders 43 retract, driving the second cutter 45 to move downward to cut the film, thereby separating the front and rear sealing plates. During the cutting, the substrate 41 moves synchronously with the perforated plates, so there is no need to stop the transmission of the perforated plates during the cutting, thus avoiding affecting the sealing efficiency of the perforated plates.

[0023] like Figure 2 and 3 As shown, the sealing assembly 3 includes two corresponding mounting plates 31, and a rotating roller 32 is rotatably connected between the two mounting plates 31. A first reduction motor 33 is fixedly connected to one side of one of the mounting plates 31, and the output shaft of the first reduction motor 33 is fixedly connected to one end of the rotating roller 32.

[0024] According to the above structure, the film roll is installed between two mounting plates 31, and the film is wrapped around the bottom end of the rotating roller 32. Under the pressure of the rotating roller 32, the film is attached to the perforated plate.

[0025] like Figures 2-5As shown, both sides of the frame 1 are provided with sliding grooves 11, and sliding rods 12 are provided inside the sliding grooves 11. Slider 46 are symmetrically fixedly connected to both ends of the base plate 41. The slider 46 is slidably connected inside the corresponding sliding groove 11, and the sliding rod 12 passes through the corresponding slider 46. The bottom end of the base plate 41 is fixedly connected with a waist-shaped ring 410. The inside of the rotating plate 411 is provided with a rotating plate 411. The two sides of the inner wall of the waist-shaped ring 410 are provided with equidistant first teeth 412. The side wall of the rotating plate 411 is provided with equidistant second teeth 413. The second teeth 413 are meshed with the first teeth 412. The bottom of the frame 1 is fixedly connected with a base plate 49. The bottom end of the base plate 49 is fixedly connected with a second reduction motor 414. The output shaft of the second reduction motor 414 is fixedly connected to the bottom end of the rotating plate 411.

[0026] According to the above structure, during cutting, the second reduction motor 414 drives the rotating plate 411 to rotate. The central angle of the side wall of the rotating plate 411 occupied by several second teeth 413 is 120°. By driving the rotating plate 411 to rotate one revolution, the second teeth 413 first engage with the first teeth 412 on one side of the waist ring 410, driving the waist ring 410 and the substrate 41 to move to the right. Then, the second teeth 413 engage with the first teeth 412 on the other side of the inner wall of the waist ring 410, driving the waist ring 410 and the substrate 41 to return. When the substrate 41 moves to the right, the cylinder 43 contracts to cut the film, and then extends to drive the top plate 42 and the second cutter 45 to rise. When the substrate 41 moves, the slider 46 slides inside the corresponding slide groove 11 and slides along the corresponding slide rod 12, providing stability when the substrate 41 moves.

[0027] like Figure 4 As shown, the top of the substrate 41 is symmetrically provided with protrusions 47, and a support roller 48 is rotatably connected between the two protrusions 47.

[0028] According to the above structure, the support roller 48 can support the perforated plate, thereby facilitating the rearward movement of the perforated plate.

[0029] The working principle of this utility model is as follows: In use, the perforated plates are placed sequentially on the roller conveyor 2. The roller conveyor 2 drives the perforated plates forward. After the sealing film assembly 3 seals the perforated plates, the perforated plates continue to move backward. When the gap between the two perforated plates is conveyed between the first cutter 44 and the second cutter 45, the substrate 41 moves forward synchronously with the perforated plates. At the same time, the two cylinders 43 retract, driving the second cutter 45 downward to cut the film, thereby separating the front and rear sealing plates. During cutting, the substrate 41 moves synchronously with the perforated plates, so there is no need to stop the transmission of the perforated plates during cutting, thus avoiding affecting the sealing efficiency of the perforated plates. The film roll is installed between the two mounting plates 31, and the film is wrapped around the bottom of the rotating roller 32. Under the pressure of the rotating roller 32, the film is attached to the perforated plates. During cutting, the second reduction motor 414 drives the film roll to move forward. When the rotating plate 411 rotates, the central angle of the side wall of the rotating plate 411 occupied by several second teeth 413 is 120°. By driving the rotating plate 411 to rotate one revolution, the second teeth 413 first engage with the first teeth 412 on one side of the waist ring 410, driving the waist ring 410 and the substrate 41 to move to the right. Then, the second teeth 413 engage with the first teeth 412 on the other side of the inner wall of the waist ring 410, driving the waist ring 410 and the substrate 41 to return. When the substrate 41 moves to the right, the cylinder 43 contracts to cut the film, and then extends to drive the top plate 42 and the second cutter 45 to rise. When the substrate 41 moves, the slider 46 slides inside the corresponding slide groove 11 and slides along the corresponding slide rod 12, providing stability when the substrate 41 moves. The support roller 48 can support the perforated plate, thereby facilitating the backward movement of the perforated plate.
