Description

Technical Field

[0001] This utility model relates to the technical field of profile cutting devices, and in particular to a cutting device for door and window profiles. Background Technology

[0002] In the fields of architecture, home furnishing and industry, doors and windows are core components for spatial division and environmental interaction. Their quality and assembly precision directly depend on the upstream profile processing technology. Cutting, as a key preliminary step in profile processing, has a decisive impact on the splicing and sealing performance, structural stability and appearance consistency of subsequent door and window frames. Compared with traditional stainless steel, the new material polyurethane fiberglass has high strength, excellent wind pressure resistance, and can achieve ultra-large size narrow frame design.

[0003] The following problems or drawbacks arise during the use of a current door and window profile cutting device: First, the traditional cutting device's fixing mode is too simple, only fixing the material. When the material's cutting position changes, it needs to be disassembled and re-fixed, which is cumbersome and time-consuming. Second, cutting generates a large amount of waste residue, and traditional devices generally do not have a self-cleaning function, requiring workers to clean it, increasing their workload and wasting their time.

The protective shell 24 can prevent high-temperature debris generated during the cutting process from damaging the cleaning brush 21.

[0021] Working principle: Place the material to be cut on the top of the adjusting seat 9, rotate the two handwheels 10, which drive the worm gear 12 and worm 11 to rotate, causing the gear 15 and rack 14 to move the adjusting plate 17 to fix the material. Then, according to the required cutting position, rotate the two handwheels 7, which drive the screw 8 to rotate, causing the adjusting seat 9 to move back and forth. The adjusting seat 9 moves the material, allowing the cutter 5 to cut the material at different positions. After the material is fixed, start the device and pull the cutting handle 6, causing the cutting shell 3 to drive the cutter 5 to rotate around the connection between the cutting shell 3 and the fixed table 2 to cut the material. After cutting, release the cutting handle 6. Due to the action of the spring 4, the cutting shell 3 will return to its original position with the cutter 5. When all the material has been cut, start the device. The motor 18 drives the screw 19 to rotate, causing the cleaning rod 20 to move forward with the cleaning brush 21. During the movement, since the cleaning rod 20 is connected to the rack 22, the rack 22 moves forward with the cleaning rod 20. During the movement, the rack 22 drives the gear 23 to rotate, causing the protective shell 24 to rotate. When the protective shell 24 rotates to the top, the buckle at the top of the protective shell 24 squeezes the spring 28 into the slot 16. The cleaning brush 21 continues to move forward, cleaning the cutting residue into the collection shell 25 and into the recycling bin 26. Then the motor 18 rotates in the opposite direction, causing the cleaning brush 21 to reset. During the reset process, the gear 23 meshes with the rack 22 again, and the rack 22 drives the gear 23 to rotate again, causing the buckle to break free from the slot 16 and the protective shell 24 to rotate downwards to reset.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
