[0042] The utility model provides a trimming device for processing sealing strips, according to the attached manual Figure 1 To Attachment Figure 5 It can be seen that a trimming device for processing a sealing strip mainly includes the following parts or components: a fixed base 10, a movable frame 30, a clamping plate 40, a baffle 50, and a collecting tank 54. The connection relationship of each part or component is as follows:

[0043] A support plate 11 is provided on the fixed base 10, and two trimming knives 12 are symmetrically provided on the support plate 11. The two trimming knives 12 can move relative to or opposite to each other under the action of the driving mechanism 20 on the support plate 11. A loading base 13 and a waste base 14 are respectively provided on the fixed base 10 on the front and rear sides of the trimming knife 12; a moving frame 30 is provided on the loading base 13, and reciprocates along the length direction of the loading base 13 under the action of the moving mechanism 31; two clamping plates 40 are symmetrically provided on the loading base 13, and are connected with the moving mechanism 31 to move back and forth along the length direction of the loading base 13; two clamping plates 40 are symmetrically provided on the loading base 13, and are connected with the moving mechanism 31 to move back and forth along the length direction of the loading base 13; two clamping plates 40 are symmetrically provided on the loading base 13, and are connected with the moving mechanism 31 to move back and forth along the length direction of the loading base 13; two clamping plates 40 are connected to ... A first guide shaft 41 horizontally arranged on the frame 30 is slidably connected, and an adjusting component 42 arranged on the movable frame 30 can drive the two clamping plates 40 to move closer to or away from each other; a blanking channel 51 is arranged on the loading base 13, and a first rotating shaft 52 is arranged on the two baffles 50. The two first rotating shafts 52 are connected to and penetrate the rotating shafts of the side plates 53 of the loading base 13, and are connected to the flipping component 55. Under the action of the flipping component 55, they rotate in opposite directions; a collecting trough 54 is arranged on the fixed base 10 below the blanking channel 51.

[0044] After the sealing strip is delivered to the loading base 13, the adjusting component 42 will drive the two clamping plates 40 to clamp it, and then the moving mechanism 31 will drive the moving frame 30 to move toward the trimming knife 12, at which time the clamping plate 40 and the sealing strip fixed by the clamping plate 40 will be driven to move synchronously. When the sealing strip is located between the two trimming knives 12, the two trimming knives 12 can be driven by the driving mechanism 20 to approach each other, so that the trimming knife 12 can trim the end of the sealing strip.

[0045] After the trimming operation is completed, the moving mechanism 31 drives the moving frame 30 to move away from the trimming knife 12, so that the two clamping plates 40 on the moving frame 30 drive the trimmed sealing strip to reset, and then the two clamping plates 40 send the sealing strip away under the action of the adjusting assembly 42, while the two baffles 50 open the blanking channel 51, so that the trimmed sealing strip falls into the collecting groove 54, completing the collection, reducing manual labor, and effectively improving the trimming efficiency.

[0048] When the piston rod of the first hydraulic cylinder 21 is extended or retracted, the fourth connecting rod 233 arranged at the end of the first connecting rod 22 can drive the third connecting rod 232 to swing with its first end as the center, and then the second connecting rod 231 connected to the third connecting rod 232 drives the trimming knife 12 to rise and fall, and the other second connecting rod 231 parallel to it can ensure that the trimming knife 12 remains horizontal, preventing the trimming knife 12 from tilting and affecting the trimming effect.

[0049] As an embodiment, according to the attached Figure 3 It can be seen that the loading base 13 is provided with a first slide rail 32 along its length direction, and the lower end of the mobile frame 30 is connected to the first slide seat 33 on the first slide rail 32. The movement of the mobile frame 30 can be guided to ensure stability and accuracy during the movement, which is conducive to adjusting the position of the sealing strip.

[0050] In this embodiment, according to the specification Figure 3It can be seen that the moving mechanism 31 includes: an intermittent push rod 311 is parallel to the first slide rail 32, and its first end is connected to the moving frame 30, and the second end is slidably connected to and penetrates the side plate 53 of the loading base 13, and is provided with an annular closed guide portion 312; the first motor 313 is arranged on the side plate 53, and a rotating rod 314 is arranged at the output end, and a sliding rod 315 is arranged at the free end of the rotating rod 314, and the sliding rod 315 slides in a circular manner in the guide portion 312, thereby driving the intermittent push rod 311 to reciprocate.

At this time, the first motor 313 drives the rotating rod 314 to rotate, and the sliding rod 315 set at its free end circulates in the guide part 312, thereby driving the movable frame 30 to move along the length direction of the first slide rail 32, so as to adjust the position of the seal, reduce manual operation, and improve trimming efficiency.

[0052] When the slide bar 315 slides in the linear guide groove, the intermittent push rod 311 can be driven to move back and forth, and when the slide bar 315 slides in the arc guide groove, the intermittent push rod 311 can be kept stationary.

Since the two first racks 553 are respectively located on both sides of the two first gears 551, when the two first racks 553 move in the same direction, the two first gears 551 can be driven to rotate in opposite directions, thereby controlling the baffle 50 to open or close the blanking channel 51, and the structure is simple.

[0055] In this embodiment, according to the specification Figure 4It can be seen that the adjustment component 42 includes: an adjustment shaft 421 which is parallel to the first guide shaft 41 and rotatably arranged on the movable frame 30, on which two threaded sections with opposite rotation directions are arranged, and the two threaded sections are respectively threadedly connected to the two clamping plates 40; a second motor 422 is arranged on the movable frame 30, and its output end is connected to the adjustment shaft 421.

[0056] Two threaded sections with opposite rotation directions are arranged on the adjusting shaft 421. By driving the adjusting shaft 421 to rotate through the second motor 422, the two clamping plates 40 can be moved closer to or farther away from each other, thereby clamping or releasing the seal. The structure is stable, and sufficient supporting force and carrying capacity can be provided, thereby ensuring the stability and reliability of the clamping plate 40 in clamping the sealing strip.
