The support plate 34 has a groove 38 on one side, and the slider 37 is slidably set in the corresponding groove 38. When the adjusting motor 31 works, the output shaft of the adjusting motor 31 drives the screw 32 to rotate tensilely. The rotation of the screw 32 drives the screw sleeve 35 to move, and the slider 37 moves along the groove 38, which can guide the screw sleeve 35. The screw sleeve 35 can drive the cutting component 6 to move, thereby realizing the cutting of the sealing strip.

[0023] Fixing components 4 are provided on both sides of the workbench 2. The fixing components 4 cooperate with the top surface of the workbench 2. The fixing components 4 include gears 42 and racks 43. The racks 43 are meshed on both the upper and lower sides of the gears 42. Several evenly distributed U-shaped seats 44 are fixedly installed on the bottom surface of the workbench 2 and the top surface of the base 1. L-shaped frames 45 are slidably installed in the U-shaped seats 44. The racks 43 are fixedly connected to the corresponding racks 43. Two gears 42 are fixedly connected by a rotating rod 46. The end of the rotating rod 46 passes through the corresponding vertical plate 5 and is rotatably connected to the vertical plate 5. The height of the lower L-shaped frame 45 is higher than that of the lower L-shaped frame 45. A fixing plate 47 is fixedly installed inside the upper part of the L-shaped frame 45. A fixing strip 48 is provided below the fixing plate 47. The fixing strip 48 cooperates with the top surface of the workbench 2. A screw hole 49 is opened on one side of the top surface of the fixing plate 47, and a through hole is opened on the other side of the top surface of the fixing plate 47. A vertical rod 411 is slidably installed inside the through hole 410. The lower end of the vertical rod 411 is fixedly connected to the top surface of the fixing strip 48. A bolt 412 is threaded into the screw hole 49. The lower end of the bolt 412 is rotatably connected to the top surface of the fixing strip 48. Rotating the rotating rod 46 drives the gear 42 to rotate. The rotation of the gear 42 drives the rack 43 to move. The rack 43 drives the L-shaped frame 45 to move along the U-shaped seat 44. The U-shaped seat 44 can support and guide the rack 43. The L-shaped frame 45 drives the fixing strip 48 to move through the fixing plate 47, thereby adjusting the fixing strip 48 to fix sealing strips of different sizes. Rotating the bolt 412 drives the fixing strip 48 to move up and down. The vertical rod 411 moves up and down along the through hole 410 to guide the fixing strip 48, thereby fixing sealing strips at different rear ends.

[0024] The bottom surfaces of the workbench 2 are fixedly connected to the top surface of the base 1 via vertical plates 5. Several evenly distributed cutting components 6 are mounted on the moving assembly 3. Each cutting component 6 includes a cylinder 61, a cutting blade 62, and a connecting block 63. A groove 64 is formed on the bottom surface of the connecting block 63. The upper end of the cutting blade 62 is inserted into the groove 64, and the lower end of the cutting blade 62 engages with the top surface of the workbench 2. Clamping plates 65 are provided on both sides of the cutting blade 62, engaging with the upper end of the cutting blade 62. The clamping plates 65 and the inner wall of the groove 64 are connected by several... Spring 66 is fixedly connected, and the top surface of connecting block 63 is fixedly connected to horizontal plate 36 via cylinder 61. When cylinder 61 is working, the telescopic end of cylinder 61 drives the cutting blade 62 to move up and down through connecting block 63. When the sealing strip needs to be cut, the lower end of the cutting blade 62 contacts the sealing strip. When the cutting blade 62 needs to be replaced, the clamping plate 65 is pushed so that the clamping plate 65 no longer contacts the cutting blade 62, and the cutting blade 62 can be taken out in the groove 64 to replace the cutting blade 62.

[0025] Both sides of the cutting component 6 are provided with clamping components 7. The clamping component 7 includes a clamping rod 71 and a clamping wheel 72. Both sides of the bottom surface of the connecting block 63 are provided with guide grooves 73 with a T-shaped cross section. The upper end of the clamping rod 71 is T-shaped and is slidably disposed in the guide groove 73. The upper end of the clamping rod 71 is fixedly connected to the inner wall of the guide groove 73 by a thrust spring 74. The lower end of the clamping rod 71 is provided with a spherical groove 75. The clamping wheel 72 is rotatably disposed in the spherical groove 75. The clamping wheel 72 is connected to the cutting component 6. The top surface of the worktable 2 is matched. When the sealing strip is being cut, the pressure rod 71 is pushed down along the guide groove 73 under the action of the thrust spring 74, so that the pressure wheel 72 contacts the sealing strip. The pressure wheel 72 presses the sealing strip, which facilitates the cutting blade 62 to cut the sealing strip. This prevents the sealing strip from moving during cutting and avoids affecting the cutting effect. The pressure wheel 72 rolls in the spherical groove 75, which can reduce the friction between the pressure rod 71 and the sealing strip.

[0026] Both the clamping component 7 and the cutting component 6 are fitted to the top surface of the worktable 2.

[0027] Working principle:

[0028] Place the sealing strip to be cut on the top surface of workbench 2. Rotate the rotating rod 46, which drives the gear 42 to rotate. The rotation of the gear 42 drives the rack 43 to move. The rack 43 drives the L-shaped frame 45 to move along the U-shaped seat 44. The U-shaped seat 44 supports and guides the rack 43. The L-shaped frame 45 drives the fixing strip 48 to move through the fixing plate 47, thereby adjusting the fixing strip 48 to fix sealing strips of different sizes. Rotate the bolt 412, which drives the fixing strip 48 to move up and down. The vertical rod 411 moves up and down along the through hole 410 to guide the fixing strip 48, thus fixing sealing strips at different rear ends. The cylinder 61 works, and the telescopic end of the cylinder 61 drives the cutting blade 62 to move up and down through the connecting block 63. When the sealing strip needs to be cut, the lower end of the cutting blade 62 contacts the sealing strip; when the cutting blade 62 needs to be cut further... When changing the cutting blade 62, push the clamping plate 65 so that it is no longer in contact with the cutting blade 62, and the cutting blade 62 can be removed from the groove 64, thus changing the cutting blade 62. When cutting the sealing strip, the pressure rod 71 is pushed down along the guide groove 73 by the thrust spring 74, so that the pressure wheel 72 contacts the sealing strip, pressing the sealing strip down, which facilitates the cutting blade 62 to cut the sealing strip and prevents the sealing strip from moving during cutting, thus avoiding affecting the cutting effect. The pressure wheel 72 rolls in the spherical groove 75, which reduces the friction between the pressure rod 71 and the sealing strip. Adjust the motor 31 to work, and the output shaft of the motor 31 drives the lead screw 32 to rotate. The rotation of the lead screw 32 drives the threaded sleeve 35 to move, and the slider 37 moves along the slide groove 38, which can guide the threaded sleeve 35. The threaded sleeve 35 can drive the cutting assembly 6 to move, thus realizing the cutting of the sealing strip.
