Description

Technical Field

[0001] This utility model belongs to the field of PVC pipe fitting production technology, specifically relating to an automatic cutting device for pipe production. Background Technology

[0002] PVC alloy is a composite material obtained by blending and modifying various resins with PVC as the main component. The word "alloy" here has no relation to metal. PVC alloy is a new type of high-performance, functional, and specialized material obtained through physical blending or chemical grafting methods. The production process of PVC pipe fittings is as follows: First, PVC resin is prepared as the main raw material, along with some additives such as stabilizers, fillers, lubricants, and pigments. These additives are used to improve the performance and stability of PVC pipes. Then, the raw materials are mixed and compounded. The mixture is fed into an extruder and pushed into the die. Through the specific shape of the die, the PVC mixture is extruded into a tubular shape. The extruded PVC pipe is fed into a cooling table or cooling water tank for rapid cooling and curing. After cooling and setting, the PVC pipe is cut to the required length. Finally, the pipe fittings are inspected to ensure quality before being packaged and shipped.

[0003] Domestic utility model patent application number 202323277075.8 discloses a PVC pipe cutting device, relating to the field of pipe cutting technology. The device features a base with two auxiliary support brackets fixedly connected in a linear array at its bottom end. A motor is installed at the front end of the base. This addresses the limitation of existing pipe cutting devices, which require pipe cutting for subsequent assembly in various environments. The lack of an effective pressure-limiting structure during cutting results in poor cutting stability. By incorporating a heatable cutter, the device can assist in cutting by activating a heating component installed at the front end of support bracket A to heat the inside of the cutter. While the aforementioned utility model features a heatable cutter, and PVC material is relatively easy to cut with a high-speed rotating cutter, the heated cutter can easily melt the cut surface, affecting the smoothness of the pipe ends. Furthermore, this utility model can only cut pipes of one size and is not suitable for fixing pipes of various sizes. Utility Model Content

An adjustment frame (6) is fixedly installed at the bottom of the connecting plate (62) and fixedly installed on the side of the mounting frame (1). The top of the adjustment frame (6) is fixedly connected to the bottom of the connecting plate (62) by two sets of bearing springs (61). The overall height of the positioning box (2) can be adjusted by rotating the four sets of threaded rods (28) so that the equipment can be used for cutting pipes of various sizes. When the height of the conveyor roller (3) is fixed, the larger the pipe diameter, the higher the position of the placement groove (24) needs to be. Adjust the threaded rod (28) to make the pipe fit the position of the placement groove (24), thereby increasing the adjustability of the equipment and making it suitable for cutting pipes of various sizes. The positioning box (2) has an installation groove (23) at the top of the placement groove (24), and two sets of hydraulic cylinders (4) are fixedly installed inside the installation groove (23). The bottom of the hydraulic cylinder (4) is connected to the clamping frame (26). The hydraulic cylinder (4) pushes the clamping frame (26) downward to position and clamp the pipe, ensuring the stability of the pipe during the cutting process, thereby reducing the error caused by the shaking of the pipe.

[0030] The positioning box (2) has a fixing groove (25) at the bottom of the placement groove (24), and three sets of pads (29) are installed on the fixing groove (25). Multiple sets of shock-absorbing springs (291) are fixedly installed between the bottom of the pads (29) and the fixing groove (25). According to the different sizes of pipe fittings, the positioning box (2) is adjusted to a suitable height for use. The pipe fitting is placed on the pad (29) and pushed so that one end of the pipe fitting extends to the bottom of the cutting blade (22). After determining the cutting position, the hydraulic cylinder (4) pushes the clamping frame (26) to clamp and position the pipe fitting to ensure the stability of the pipe fitting during the cutting process. Finally, the drive motor (5) is started to drive the cutting blade (22) to rotate at high speed to cut the pipe fitting. A waste bin (7) is placed at the bottom of the cutting blade (22). The waste bin (7) collects the waste generated by the pipe fitting during the cutting process, reducing the pollution to the environment.

[0031] Example: Adjust the positioning box (2) to a suitable height for use according to the different sizes of pipe fittings. Adjust the overall height of the positioning box (2) by rotating the four sets of threaded rods (28) to make the pipe fitting fully adapt to the position of the placement slot (24). Push the pipe fitting placed on the transmission roller (3) to move it to the pad (29) and push it so that one end of the pipe fitting extends to the bottom of the cutting blade (22). After determining the cutting position, the hydraulic cylinder (4) pushes the clamping frame (26) to clamp and position the pipe fitting to ensure the stability of the pipe fitting during the cutting process. Finally, start the drive motor (5) to drive the cutting blade (22) to rotate at high speed to cut the pipe fitting.
