Description

Technical Field

[0001] This utility model relates to the technical field of edge sealing and grooving equipment, specifically to an edge sealing and grooving device for PVC doors and windows. Background Technology

[0002] PVC windows and doors are made primarily from polyvinyl chloride (UPVC) resin, with added stabilizers, colorants, fillers, UV absorbers, etc. The resin is extruded into profiles, which are then cut, welded, or screwed together to form window and door frames. Sealing strips, weatherstripping, and hardware are added. To enhance the rigidity of the profiles, steel reinforcement (stiffening ribs) are added to the cavities of profiles exceeding a certain length. Windows and doors made in this way are called PVC windows and doors. After the PVC windows and doors are formed from the profiles, edge sealing is added to the edges of the windows and doors. Grooves are cut on both sides of the edge sealing to fit the sliding grooves at both ends of the windows and doors.

[0003] A search revealed a utility model patent in China, CN213826605U, which discloses a grooving device for sealing edges of PVC windows and doors. The device is roughly described as including a frame, a folding mechanism, a drive mechanism, and a fixing mechanism. The frame has an internal collection box. During use, a fixing plate moves downwards, causing a sliding column to move downwards, which in turn causes a pressure plate to move downwards, which in turn causes a rubber pad to move downwards. When the rubber pad contacts the material, the rubber pad, pressure plate, and sliding column stop moving. When the pressure plate and fixing plate are relatively displaced, a spring is compressed, exerting a downward force on the pressure plate, thus pressing the rubber pad against the material. This device utilizes the pressure of the hydraulic telescopic column to compress the material, reducing equipment costs and maximizing energy utilization. While the above-mentioned device reduces processing costs, it still has certain shortcomings. For example, although it eliminates the need for additional driving force, it consumes the power of the hydraulic telescopic column. If the grooving force needs to remain constant, the power of the hydraulic telescopic column needs to be increased, which also increases consumption. Moreover, the material is fixed by spring compression, which is not stable. During grooving, each impact puts a lot of pressure on the spring. After multiple high-intensity compressions, the spring will experience metal fatigue, reducing its original elasticity. Therefore, the spring needs to be inspected or replaced frequently to prevent material displacement during grooving due to spring loosening, which also increases costs and makes stable grooving difficult. To address these issues, we propose a grooving device for PVC window and door edge sealing. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a grooving device for PVC window and door edge sealing, which solves the problems mentioned in the background art. Although the above-mentioned device eliminates the need for additional driving force, it consumes the force of the hydraulic telescopic column. If the grooving force needs to remain constant, the power of the hydraulic telescopic column needs to be increased, which also increases consumption. Moreover, it uses a spring-pressing method to fix the material, which is not stable. During grooving, there is an impact every time, which puts a lot of pressure on the spring. After multiple high-intensity compressions, the spring will experience metal fatigue, thereby reducing its original elasticity. Therefore, the spring needs to be inspected or replaced frequently to prevent material displacement during grooving due to spring loosening. This also increases costs and makes it difficult to achieve stable grooving.
