Description

Technical Field

[0001] The utility model relates to the technical field of door and window processing equipment, in particular to a PVC profile cutting device for door and window production. Background Technique

[0002] PVC profiles, also known as plastic steel profiles, mainly consist of PVC chemically, so they are also called PVC profiles. They are a widely used new type of building material. Due to their excellent physical properties such as rigidity, elasticity, corrosion resistance, and anti-aging performance, they are usually used as good substitutes for non-ferrous metals such as copper, zinc, and aluminum. In building construction, they are mainly used for sliding, casement windows, guards, pipes, and ceiling materials. Through new technological processes, they are also widely used in automotive engine protection plates. They are not only light in weight but also good in toughness, with excellent rigid properties, and are sometimes called alloy plastic steel.

[0003] During the production process of PVC doors and windows, the cutting of PVC profiles is an important link. After retrieval, the Chinese patent application number is: CN202121310711.0, which discloses a cutting device for the production and processing of PVC profiles, including a processing table. Two I-shaped blocks are fixedly installed on the upper right part of the processing table. Two sliders are movably connected to the upper ends of the two I-shaped blocks. A cross plate is fixedly connected to the upper ends of the four sliders. A base is fixedly connected to the upper left part of the processing table. A motor is fixedly connected to the upper end of the base. A protective cover is fixedly installed at the right end of the base. The output end of the motor is fixedly connected to a saw blade, and the saw blade is located inside the protective cover. A limiting device is arranged on the upper part of the outer surface of the protective cover. The cutting device for the production and processing of PVC profiles of this utility model can adapt to different protection angles and improve the flexibility of cutting through the setting of a movable cross plate and a limiting device. The structure is simple and firm, with strong flexibility and high safety performance.

[0004] The above technical solution lacks the fixing function for PVC profiles, with low cutting accuracy. During the cutting process, the PVC profiles will shake, resulting in inconsistent cut sections, which not only affects the quality and efficiency of door and window production but also wastes materials and even causes some materials to be scrapped. Therefore, we need to propose a PVC profile cutting device for door and window production. Content of the Utility Model

[0031] Cutting mechanism for cutting plastic-steel profiles; the cutting mechanism includes a fixed seat 3 arranged at the bottom of the top plate 2. A saw blade 4 is rotatably installed in the inner cavity of the fixed seat 3. The saw blade 4 is driven by a first motor 5. A notch 16 corresponding to the saw blade 4 is provided on the processing table 1. The first motor 5 is fixedly installed on one side outer wall of the fixed seat 3, and the output end of the motor is in transmission connection with the saw blade 4.

[0032] Positioning mechanism for positioning plastic-steel profiles to be processed; the positioning mechanism includes two groups of convex seats 6 symmetrically arranged on the processing table 1. A placement groove 7 for placing plastic-steel profiles is provided on the convex seat 6. Two groups of clamping blocks 8 are symmetrically arranged in the placement groove 7, and the two groups of clamping blocks 8 can move closer or farther away in the placement groove 7.

[0033] By setting a main body structure including a processing table 1, a support frame, and a top plate 2, a cutting mechanism including a fixed seat 3 and a saw blade 4, and a positioning mechanism including a convex seat 6. A placement groove 7 is provided on the convex seat 6, and two groups of clamping blocks 8 are installed in the placement groove 7 to position the plastic-steel profiles. The structure of this device is simple and easy to use. Through the setting of the positioning mechanism, it can play a good role in positioning and fixing during the cutting process of plastic-steel profiles, improve the accuracy of cutting processing and the efficiency of window and door processing, and ensure the consistency of the cut and the quality of window and door production and processing.

[0034] A cavity 11 communicating with the placement groove 7 is provided at the bottom of the convex seat 6. The bottom parts of the two groups of clamping blocks 8 located in the placement groove 7 are respectively welded with a first moving plate 9 and a second moving plate 10. The first moving plate 9 and the second moving plate 10 are both slidably installed inside the cavity 11. Both the first moving plate 9 and the second moving plate 10 are arranged in a U shape. A top rack 12 is provided at the bottom of the lower arm of the first moving plate 9, and a top rack 12 is provided at the top of the lower arm of the second moving plate 10. A second motor 14 is fixedly installed on one side outer wall of the convex seat 6.

Since the driving gear 15 is connected to the output end of the second motor 14, and the driving gear 15 meshes with the upper rack 12 and the lower rack 13 respectively up and down, when the driving gear 15 rotates, the first moving plate 9 and the second moving plate 10 can move closer or farther away in the cavity 11, thereby driving the two groups of clamping blocks 8 in the placement groove 7 to clamp and position or loosen and remove the plastic-steel profile. After the positioning is completed, the first motor 5 is started to drive the saw blade 4 to rotate, and at the same time, the top plate 2 is controlled to descend by the air cylinder 17 to cut the plastic-steel profile.

[0036] In addition, by driving the driving gear 15 with the second motor 14, the distance between the two groups of clamping blocks 8 in the placement groove 7 can be flexibly adjusted, so that plastic-steel profiles of different thicknesses can be flexibly adapted, facilitating the positioning of plastic-steel profiles of different sizes and specifications, and greatly improving the applicable range of this device.

[0037] Please refer to Figure 4 :

[0038] An anti-slip pad 18 is adhesively provided on the side wall of the clamping block 8, and the anti-slip pad 18 is a rubber pad with anti-slip lines.

[0039] By providing the anti-slip pad 18 made of rubber on the clamping block 8, when the clamping block 8 clamps the plastic-steel profile, it can avoid damaging the plastic-steel profile with too much force, ensuring that the plastic-steel profile has qualified quality and facilitating subsequent window and door processing.
