One end of the baffle is horizontally fixedly installed on one side of the support rods. The cutting assembly is provided at the bottom of the top plate, and the feeding assembly is provided on one side of the top of the workbench. The aforementioned patent uses four cutting blades that are fixed at equal intervals to achieve equidistant cutting of door and window profiles. However, the spacing between the four blades is fixed, so the size of the profile cutting cannot be adjusted, resulting in a limited range of applications. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a processing device for door and window profiles, which solves the technical problem that the fixed spacing between the four blades makes the profile cutting size unadjustable, resulting in a limited range of applications.

The support frame is slidably connected to the processing table, and multiple support plates for placing profiles are distributed horizontally on the processing table. Each support plate has a longitudinally arranged cutting groove in its middle.

[0005] Based on the above technical solution, the processing device for door and window profiles of this utility model can be further improved as follows: Furthermore, a guide plate is fixedly installed in the middle of the bottom wall of the support plate.

[0023] Optionally, in the above technical solution, a cylinder B27 is fixedly installed on the processing table 1 via a cylinder seat. The movable end of the cylinder B27 extends to the left, and its end is fixedly connected to the rear wall of the left guide plate 23 via a connecting plate B26.

[0024] Optionally, in the above technical solution, an extension plate 22 is fixedly installed on the middle of the left wall of the left end support plate 2 and the middle of the right wall of the right end support plate 2. A horizontally arranged placement groove 220 is opened on the extension plate 22. The bottom wall of the placement groove 220 is flush with the top wall of the support plate 2. A pressure plate 221 is installed on the top wall of the extension plate 22 by bolts.

[0025] The extension plate 22 and the pressure plate 221 are provided with threaded holes at corresponding positions for mounting bolts.

[0026] When the profile is placed on the placement groove 220, its top is slightly higher than the top wall of the extension plate 22, so that the placement of the pressure plate 221 can press the profile tightly.

[0027] Optionally, in the above technical solution, a guide block 41 is fixedly installed on the bottom wall of the support frame 11, the guide block 41 is fixedly installed on the slider 42, the slider 42 is slidably connected to the slide rail 43, and the slide rail 43 is arranged horizontally and fixedly installed on the top wall of the processing table 1 through a pad.

[0028] Furthermore, two fixing blocks 15 are symmetrically fixed on the bottom wall of the connecting plate A13. A damping rod 16 is installed below the fixing block 15. A spring 17 is sleeved on the damping rod 16. A pressure block 18 is installed below the spring 17. Furthermore, it also has a ball screw, with a guide block 41 sleeved on the outer circumferential surface of the ball screw nut 44 and fixedly connected to the nut 44; both ends of the ball screw 45 are rotatably connected to the ear plate 46 through bearings, and the ear plate 46 is fixed to the left and right ends of the slide rail 43; a motor base 47 is fixedly installed on the right end of the right ear plate 46, and a second motor 48 is fixedly installed on the motor base 47, with the output axis of the second motor 48 extending to the left and connected to the end of the ball screw 45.

[0029] Preferably, there is an odd number of guide plates 23, and the number is not limited to that shown in the figure. The middle guide plate 23 is fixed on the guide rod 24. Preferably, a linear bearing is sleeved in the through hole of the guide plate 23 (except for the middle guide plate 23).

[0030] All cylinders are guide rod cylinders, using the cylinder control method commonly used in existing technology, and are connected to an external air source; the second motor 48 is a stepper motor, which is convenient for controlling its start and stop.

[0031] Among them, the maximum length between multiple support plates 2 and the distance between the left end cutting groove 21 and the right end cutting groove 21 are less than the length of the lead screw 45, that is, less than the maximum lateral stroke of the cutting blade body 14.

[0032] Working principle: When in use, place the sound insulation profile on multiple support plates 2, adjust the spacing of the support plates 2 according to the required cutting length, so that the profile to be cut is simultaneously located on the extension plates 22 on both the left and right sides, located in the placement groove 220, and the pressure plate 221 is placed on it. Tighten the bolts to press the profile, and the bottom of the profile simultaneously contacts the bottom wall of the placement groove 220 and the top wall of the support plate 2. When the support frame 11 moves laterally and the cutting blade body 14 moves to the position corresponding to the longitudinal direction of the cutting groove 21, the cylinder A12 is activated to press down the cutting blade body 14 (firstly, the first motor 142 is activated to drive the cutting blade body 14 to rotate, then the output end of the cylinder A12 drives the connecting plate A13 to push down, the fixing blocks 15 installed on both sides of the connecting plate A13 press down, the spring 17 is compressed by pressure, and the pressure block 18 presses the profile until the tip of the cutting blade body 14 touches the bottom wall of the cutting groove 21) to cut the profile. The support frame 11 moves to the left step by step to cut the profile at each cutting groove 21. The spacing adjustment method is as follows: Activate cylinder B27 (using an existing cylinder that can be connected to an air source) to retract or extend its movable end. This causes the connecting plate B26 to move the left guide plate 23 to the right or left. Under the action of the scissor assembly (resulting in changes in length and width), the guide plate 23 on the right side of the middle guide plate 23 moves synchronously to the left or right, while the guide plate 23 on the left side of the middle guide plate 23 moves synchronously to the right or left. This achieves synchronous movement to adjust the spacing. Adjusting the spacing between the two support plates 2 adjusts the spacing between the two cutting grooves 21, ensuring that the spacing remains consistent (the error will not exceed 3mm). The lateral movement of the support frame 11 is as follows: the second motor 48 (capable of forward or reverse rotation) is started to drive the lead screw 45 to rotate in place. The nut 44 moves laterally along the lead screw 45 under the action of the slider 42. When it moves to the position corresponding to the cutting groove 21, the second motor 48 stops. Optical fibers can be installed on the rear side of each cutting groove 21. Matching optical fibers (using existing products) are installed on the support frame 11 at the position corresponding to the cutting blade body 14. Through a many-to-one method, one cutting blade body 14 corresponds to multiple cutting grooves 21.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
