Technical Field

[0001] The utility model relates to the technical field of sealing strip trimming devices, and particularly relates to a trimming device for the production and processing of hardware sealing strips. Background Technique

[0002] During the production process of sealing strips, a trimming machine is usually required for trimming. For example, the Chinese utility model patent with the publication number CN219968106U provides a trimming mechanism for a rubber sealing strip of a protective door, including an operating table. Reinforcing plates are integrally formed on the front and back sides at both left and right ends of the operating table, and a positive and negative motor is fixedly installed at the right end of each of the two reinforcing plates on the right side. Output shafts of the two positive and negative motors are fixedly installed with adjusting screws. Guide grooves are formed at both front and back ends of the operating table, and the two adjusting screws are respectively movably installed in the guide grooves on the front and back sides. A trimming mechanism is slidably installed in the two guide grooves together, and the trimming mechanism is threadedly connected with the two adjusting screws. A controller is arranged at the left end of the operating table. Through two pressing wheels, the sealing strip can be effectively fixed and limited, preventing the sealing strip from shifting during trimming, improving the trimming quality of the sealing strip. At the same time, by adjusting the distance between the two cutting knives, it can be adapted to protective doors of different sizes, with strong versatility.

[0003] However, one disadvantage of this device is that when the cutting knife of this device trims the sealing strip, the cutting knife directly contacts and rubs against the workbench, resulting in wear of the cutting knife and the operating table. Content of the Utility Model

Detailed implementation manner

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-4 , the present invention provides a technical solution: a trimming device for the production and processing of hardware sealing strips, including a workbench 1, a slide rail 2 is provided on the workbench 1, a gantry 3 is slidably installed on the slide rail 2, and a pair of first electric push rods 12 are connected between the slide rail 2 and the first gantry 3. The first gantry 3 is connected with a second electric push rod 5, and the telescopic end of the second electric push rod 5 is connected with a cutting assembly. The cutting assembly includes a cross beam 4, the cross beam 4 is connected with a pair of tool rests 6, and a spacing adjusting mechanism is arranged between the pair of tool rests 6. The lower end of the tool rest 6 is connected with a cutting knife 19, and rollers 16 for pressing the sealing strip 0 are arranged on both sides of the cutting knife 19. A pair of strip boards 9 for placing the sealing strip 0 are arranged on the workbench 1, and tool grooves 901 corresponding to the cutting knife 19 are arranged on the strip boards 9. A position adjusting mechanism is arranged between the strip boards 9 and the workbench 1;

[0020] During use, the sealing strip 0 is placed between a pair of strip boards 9. According to needs, the distance between the pair of tools is adjusted through the spacing adjusting mechanism, and then the positions of the pair of strip boards 9 are adjusted through the position adjusting mechanism so that the tool grooves 901 of the strip boards 9 correspond to the positions of the cutting knives. The second electric push rod 5 extends to move the cross beam 4 downward, so that the rollers 16 press the edge of the sealing strip 0 to limit the sealing strip 0. The tip of the cutting knife 19 penetrates the edge of the sealing strip 0 and extends into the tool groove 901. The first electric push rod 12 pushes the first gantry 3 to move on the slide rail 2, and the cutting assembly cuts the edge of the sealing strip 0. At the same time, the tip of the cutting knife 19 moves in the tool groove 901 and does not contact the workbench 1 or the strip board 9, avoiding wear caused by direct contact between the cutting knife 19 or the workbench 1.

[0021] Further, a pair of the tool holders 6 are slidably connected to the cross beam 4. The spacing adjustment mechanism includes a first screw rod 7 rotatably mounted on the cross beam 4. Threads with equal lead and opposite helix directions are provided at both ends of the first screw rod 7 and are threadedly connected to a pair of the tool holders 6. One end of the first screw rod 7 is connected with a first handle 8;

[0022] By rotating the first screw rod 7 through the first handle 8, a pair of tool holders 6 can be centered and moved on the cross beam 4. Through the above technical solution, the spacing between a pair of cutting knives 19 can be adjusted as needed.

[0023] Further, an installation groove 101 is provided on the workbench 1. A pair of strip plates 9 are slidably mounted in the installation groove 101. The position adjustment mechanism includes a pair of second screw rods 11 threadedly connected to the workbench 1. One end of the second screw rod 11 is rotatably connected to the strip plate 9, and the other end is provided with a second handle 10;

[0024] By rotating the second screw rod 11 through the second handle 10, one end of the second screw rod 11 pushes the strip plate 9 to move in the installation groove 101, so that the tool groove 901 of the strip plate 9 is aligned with the cutting knife 19.

[0025] Further, a pressing component for fixing the sealing strip 0 is provided at one end of the workbench 1. The pressing component includes a second gantry 13 fixedly mounted at one end of the workbench 1. A third electric push rod 14 is installed at the lower part of the second gantry 13. The telescopic end of the third electric push rod 14 is connected with a pressing plate 15;

[0026] When the third electric push rod 14 extends, the pressing plate 15 presses the sealing strip 0, thereby replacing manual labor to fix one end of the sealing strip 0.

[0027] Further, a sliding groove is provided on the tool holder 6. A slider 18 is slidably mounted in the sliding groove. A pair of rollers 16 are rotatably mounted on the slider 18. A spring 17 is connected between the slider 18 and the sliding groove;

[0028] Through the above technical solution, when the edge of the sealing strip 0 contacted by the rollers 16 is reached, the tool holder 6 together with the cutting knife 19 can continue to move downward, and the spring 17 is compressed. This ensures that the cutting knife 19 can penetrate the edge of the sealing strip 0 with different thicknesses, and at the same time enables the rollers 16 to keep in close contact with the sealing strip 0.

[0029] Embodiment: The sealing strip 0 is placed between a pair of strip plates 9. According to requirements, the distance between a pair of cutting knives 19 is adjusted by rotating the first screw rod 7 with the first handle 8. The second screw rod 11 is rotated with the second handle 10. One end of the second screw rod 11 pushes the strip plate 9 to move in the installation groove 101, so that the knife groove 901 of the strip plate 9 is aligned with the cutting knife 19. The third electric push rod 14 extends to press one end of the sealing strip 0 with the pressing plate 15. The second electric push rod 5 extends to move the cross beam 4 downward, and further makes the roller 16 press the edge of the sealing strip 0 to limit the sealing strip 0. The tip of the cutting knife 19 penetrates the edge of the sealing strip 0 and extends into the knife groove 901. The first electric push rod 12 pushes the first gantry 3 to move on the slide rail 2, and the cutting assembly cuts the edge of the sealing strip 0. At the same time, the tip of the cutting knife 19 moves in the knife groove 901 and does not contact the workbench 1 or the strip plate 9, avoiding wear caused by direct contact between the cutting knife 19 or the workbench 1.
