[0021] Example: Figure 1-4As shown, this utility model provides an edge trimming and positioning device for automotive sealing strips, including a top frame 1 and a bottom frame 2. A material placement platform 21 is fixedly installed at the top of the bottom frame 2. A protective pad 22 with a groove is provided at the top of the material placement platform 21. After the automotive sealing strip is produced, it is placed on the protective pad 22. A fixed pulling mechanism 3 is fixedly installed at the bottom of the top frame 1. A punching mechanism 4 is provided on the side of the fixed pulling mechanism 3 near the end of the material placement platform 21. The fixed pulling mechanism 3 includes a structural cross frame 31, which is fixedly installed at the bottom of the equipment top frame 1. A top slide 32 is slidably mounted at the bottom of the structural cross frame 31. A flipping cross shaft 33 is rotatably mounted at the bottom of the top slide 32 via a bearing. A mounting center seat 331 is fixedly mounted at the end of the flipping cross shaft 33. Two sets of positioning mechanisms 34 are provided on the outer side of the mounting center seat 331.

[0022] A guide shaft 311 is fixedly installed on the bottom inner side of the structural frame 31. The top slide 32 is slidably installed on the outside of the guide shaft 311. A translation screw 312 is rotatably installed in the middle of the structural frame 31. A translation nut 321 that works with the translation screw 312 is fixedly clamped on the top of the top slide 32. The translation nut 321 is threaded on the outside of the translation screw 312. A drive motor 313 is fixedly installed at one end of the structural frame 31. The drive end of the drive motor 313 is fixedly installed on the shaft end of the translation screw 312. By turning on the drive motor 313, the translation screw 312 is driven to rotate, thereby driving the top slide 32 to automatically translate and slide. This, in turn, drives the positioning mechanism 34 to automatically translate and slide. The movement distance can be precisely adjusted and positioned according to the user's needs. This allows the car sealing strip to be moved to a precise length automatically, so as to trim the car sealing strip to a precise length.

[0023] The positioning mechanism 34 includes a mounting side frame 341, which is fixedly mounted on the outside of the mounting base 331. A fixed seat 342 is vertically mounted on the side of the mounting side frame 341 closest to the mounting base 331. A movable slide 343 is slidably mounted on the side of the mounting side frame 341 away from the mounting base 331. A fixed frame 344 is bolted to the outside of the fixed seat 342, and a movable frame 345 is bolted to the outside of the movable slide 343. A plurality of evenly distributed fixed slots are provided between the fixed frame 344 and the movable frame 345. A telescopic cylinder 346 is fixedly installed at the end of the mounting side frame 341 away from the mounting center seat 331 in the positioning groove 3401. The drive end of the telescopic cylinder 346 and the movable slide 343 are fixedly installed. By setting multiple positioning grooves 3401, multiple automotive sealing strips can be positioned. The ends of the automotive sealing strips are placed in the corresponding positioning grooves 3401 between the fixed frame 344 and the movable frame 345. The telescopic cylinder 346 is opened to extend and control the movable frame 345 to slide. The ends of multiple automotive sealing strips are clamped and positioned by the fixed frame 344 and the movable frame 345.

[0024] The positioning grooves 3401 in the two sets of positioning mechanisms 34 have different shapes. By setting two sets of positioning mechanisms 34, in which the positioning grooves 3401 in the two sets of positioning mechanisms 34 have different shapes, it is convenient to position and pull two different specifications of automotive sealing strips without having to repeatedly disassemble and install different fixing fixtures, making it simple and convenient to use.

[0025] A rotary cylinder 332 is fixedly installed on the bottom outer side of the top slide 32. The drive end of the rotary cylinder 332 and the shaft end of the flipping horizontal shaft 33 are fixedly installed. By opening the rotary cylinder 332, the flipping horizontal shaft 33 is driven to rotate, thereby controlling the two sets of positioning mechanisms 34 to flip and flip the positioning mechanism 34 to be used to the upper position.

[0026] The blanking mechanism 4 includes a mounting top frame 41 and a mounting base frame 42. The mounting top frame 41 is fixedly installed on the top of the structural cross frame 31 near the end of the material placement table 21. The mounting base frame 42 is fixedly installed on the bottom of the structural cross frame 31 near the end of the material placement table 21.

A first lifting cylinder 412 is fixedly mounted on the mounting top frame 41, and the drive end of the first lifting cylinder 412 is fixedly mounted to the blanking blade 43. A second longitudinal rod 421 is movably mounted on the mounting base frame 42, and the top of the second longitudinal rod 421 is fixedly mounted on the bottom of the mounting base frame 42. The device is equipped with a punching base 44, the side end of which contacts the end of the material placement table 21. A second lifting cylinder 422 is fixedly installed on the mounting base 42. The drive end of the second lifting cylinder 422 is fixedly installed on the punching base 44. The fixed pulling mechanism 3 is used to pull multiple automotive sealing strips to move a certain distance. At this time, the trimmed edge of the automotive sealing strip is located between the punching knife 43 and the punching base 44. The first lifting cylinder 412 and the second lifting cylinder 422 are extended, driving the punching knife 43 and the punching base 44 to move closer to each other. The punching knife 43 automatically punches multiple automotive sealing strips, improving the overall processing efficiency of automotive sealing strips.

[0027] Working principle: After the automotive sealing strip is produced, it is placed on the protective pad 22. Then, according to the specifications of the automotive sealing strip, the positioning mechanism 34 with the corresponding positioning groove 3401 is selected. The rotary cylinder 332 is turned on to drive the flipping horizontal shaft 33 to rotate, thereby controlling the two sets of positioning mechanisms 34 to flip and flip the positioning mechanism 34 to the upper position. Turn on the drive motor 313 to drive the translation screw 312 to rotate, thereby driving the top slide 32 to automatically translate and slide, which in turn drives the positioning mechanism 34 to automatically translate and slide to one side of the end of the material placement table 21. At this time, the end of the car sealing strip is placed in the corresponding positioning groove 3401 between the fixed frame 344 and the moving frame 345. Turn on the telescopic cylinder 346 to extend and control the moving frame 345 to slide, and clamp and position the ends of multiple car sealing strips through the fixed frame 344 and the moving frame 345. Subsequently, the drive motor 313 is turned on again, driving the translation screw 312 to rotate in the opposite direction, thereby driving the top slide 32 to automatically slide in the opposite direction, which in turn drives the positioning mechanism 34 to automatically slide away from the material table 21, pulling multiple automotive sealing strips to move precisely a certain distance. At this time, the trimmed part of the automotive sealing strip is located between the punching knife 43 and the punching base 44. The first lifting cylinder 412 and the second lifting cylinder 422 are extended, driving the punching knife 43 and the punching base 44 to move closer to each other. The punching knife 43 automatically punches multiple automotive sealing strips, improving the overall processing efficiency of automotive sealing strips.
