However, when cutting the frame, most of the time, it is necessary for the staff to measure the frame and then mark the cutting position of the frame to ensure the accuracy of the cutting size. Obviously, this method of measuring first and then marking will increase the time and physical consumption of the staff during operation as the number of frame cuts increases, thereby reducing the work efficiency and causing great inconvenience. Therefore, we have proposed a cutting device for door and window processing. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1-7 , the present utility model provides a technical solution: a cutting device for door and window processing, including an operating table 1, a cutter 11 is fixedly installed on the upper end of the operating table 1, two symmetrically arranged drive wheels 2 are rotatably installed on one side of the upper end of the operating table 1, a traction motor 20 is fixedly installed on the upper end of the operating table 1, a driving gear 28 is fixedly installed at the lower end of the traction motor 20 through its output shaft, a rotary disk 25 is rotatably installed at the lower end of the operating table 1, a driven gear 251 meshed with the driving gear 28 is fixedly installed on the periphery of the rotary disk 25, the lower ends of the two drive wheels 2 are respectively connected with meshed drive gears 21, a connecting gear 22 is fixedly installed at the lower end of one of the drive gears 21, a rack 23 meshed with the connecting gear 22 is fixedly installed at the lower end of the operating table 1, a movable plate 24 is fixedly installed at one end of the rack 23, a limit sliding groove 252 is opened at the upper end of the rotary disk 25, a movable seat 26 is slidably installed in the limit sliding groove 252, and a slide shaft 27 slidably connected with the upper end of the movable plate 24 is fixedly installed at the lower end of the movable seat 26.

[0025] Working principle: When cutting the door and window frame, install the frame between two driving wheels 2. Start the traction motor 20. Through the meshing effect between the driving gear 28 and the driven gear 251, the traction motor 20 can drive the rotating disk 25 to rotate through its output shaft. Then, through the sliding connection between the sliding shaft 27 and the movable plate 24, it can drive the rack 23 to reciprocate at the lower end of the operating table 1. The moving rack 23, through its connection with the connecting gear 22 and between the two driving gears 21, can drive the driving wheels 2 to rotate towards each other, thereby intermittently guiding the frame between the two driving wheels 2 forward. Cooperating with the cutter 11, the frame can be cut at a fixed distance;

[0026] When it is necessary to adjust the cutting distance of the frame, the position of the movable seat 26 can be adjusted in the limit sliding groove 252, and the rotation diameter of the sliding shaft 27 can be adjusted, so as to adjust the movement distance of the movable plate 24 and the rack 23, achieving the effect of adjusting the rotation angle of the driving wheel 2 and adjusting the traction distance of the frame.

[0027] As a further description of the above technical solution: A first positioning plate 261 is fixedly installed on the outer periphery of the lower end of the movable seat 26. The first positioning plate 261 is slidably connected to the lower side of the inner cavity of the limit sliding groove 252. An insertion cavity 262 is formed in the middle of the movable seat 26. A second positioning plate 264 is inserted and installed outside the insertion cavity 262. The second positioning plate 264 is mutually attached to the upper side of the inner cavity of the limit sliding groove 252. A threaded plate 263 is fixedly installed in the second positioning plate 264. The threaded plate 263 is inserted and installed in the insertion cavity 262. A threaded rod 265 that is threadedly connected to the threaded plate 263 is rotatably installed in the insertion cavity 262.

[0028] Specifically, when it is necessary to adjust the position of the sliding shaft 27, through the sliding connection between the first positioning plate 261 and the limit sliding groove 252, the movable seat 26 can be adjusted to the corresponding position in the limit sliding groove 252. Then, rotate the threaded rod 265 at the upper end of the movable seat 26. Under the restriction of the movement direction of the threaded plate 263 by the insertion connection between the insertion cavity 262 and the threaded plate 263, the rotating threaded rod 265 can drive the second positioning plate 264 to move upward to be mutually clamped with the upper side of the inner cavity of the limit sliding groove 252 through its threaded connection with the threaded plate 263, achieving the effect of positioning the movable seat 26 in the limit sliding groove 252, thereby adjusting and positioning the sliding shaft 27.

[0029] As a further description of the above technical solution: A limit rotation frame 31 is fixedly installed at the lower end of the driving wheel 2 through a connecting rod, and a limit rotation plate 3 is fixedly installed at the upper end of the driving gear 21 through a connecting rod. The limit rotation plate 3 is rotatably installed in the limit rotation frame 31; a ratchet tooth groove 32 is formed in the inner wall of the limit rotation frame 31, a jack 33 is formed in the periphery of the limit rotation plate 3, a pawl 34 that is clamped with the inner wall of the ratchet tooth groove 32 is inserted in the jack 33, and a spring 35 is fixedly installed between the jack 33 and the pawl 34.

[0030] When the rack 23 moves forward and drives the driving gear 21 to move forward, through the plug connection between the pawl 34 and the ratchet tooth groove 32, the driving wheel 2 can be driven to move forward with it, achieving the effect of pulling the frame.

[0031] When the rack 23 moves backward and drives the driving gear 21 to move backward, the limit rotation plate 3 drives the pawl 34 to rotate in the ratchet tooth groove 32, so that the two are separated from each other, preventing the rotating driving gear 21 from driving the driving wheel 2 to rotate with it, keeping the frame in a static state and preventing the frame from moving backward.

[0032] The spring 35 is provided so that when the driving gear 21 moves backward, the pawl 34 continuously contacts the ratchet tooth groove 32. When the reciprocating rack 23 switches from backward to forward movement, the driving wheel 2 can be driven to rotate forward, ensuring the pulling effect of the driving wheel 2 on the frame.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
