[0025] like Figure 1-2As shown, a plastic pipe cutting device suitable for continuous production includes a base 1. An inlet end limiting block 2 and an outlet end limiting block 3 are spaced apart on the base 1. Through holes for pipes 4 to pass through are provided in the inlet end limiting block 2 and the outlet end limiting block 3. The area between the inlet end limiting block 2 and the outlet end limiting block 3 is the cutting area. A cutting machine 5 is located above the cutting area and is connected to a lifting device, which in turn is connected to a sliding device. By setting the inlet and outlet end limiting blocks on the base to form the cutting area, and in conjunction with the structural design of the cutting machine, lifting device, and sliding device, cutting can be performed without stopping the machine during continuous pipe conveying, solving the problem of traditional fixed cutting requiring production pauses and ensuring production continuity. Simultaneously, the through holes in the limiting blocks position the pipe, ensuring accurate cutting.
[0026] Preferably, the sliding device is slidably connected to the slider 7 on the slide rail 6, and also includes a lead screw 8 for moving the slider 7. The lead screw 8 is driven to rotate by a motor 9. The sliding device adopts a combination structure of slide rail, slider, lead screw and motor. The motor drives the lead screw to rotate and drive the slider to slide, so that the cutting machine can move precisely along the slide rail. It can synchronously adjust the cutting position according to the pipe conveying speed, realize dynamic following cutting, improve the degree of automation and accuracy of cutting, and reduce manual operation.
[0027] Preferably, the lifting device is a servo electric push rod 10, the lower end of which is connected to the cutting machine 5. The servo electric push rod used in the lifting device has high-precision displacement control capabilities, allowing for precise adjustment of the cutting machine's lifting height and speed to ensure the cutting depth meets requirements. It also provides rapid response and stable control, adapting to the high-frequency, high-precision cutting needs of continuous production.
[0028] Preferably, the outlet side of the inlet end limiting block 2 is provided with a limiting groove 11, which is located on the base 1. The limiting groove on the outlet side of the inlet end limiting block can further limit the pipe material passing through the limiting block, preventing the pipe material from shaking or deviating due to force during cutting. It also forms a double positioning with the through hole of the limiting block, effectively improving the stability of the pipe material during cutting and ensuring the cutting quality.
[0029] Preferably, the inlet end limiting block 2, the outlet end limiting block 3, and the limiting groove 11 are detachably connected to the base 1. This facilitates the replacement of components of corresponding specifications according to different pipe diameters, eliminating the need for replacing the entire device, improving the device's adaptability to different pipe materials, enhancing its versatility, and reducing equipment replacement costs.
[0030] Preferred, such as Figure 3As shown, the inlet end of the pipe outlet limiting block 3 has a trumpet-shaped structure. The flared design guides the pipe smoothly into the through hole, reducing resistance and jamming during pipe insertion, optimizing the operation process, and improving the convenience and efficiency of pipe feeding. It is especially suitable for rapid feeding scenarios in continuous production.
[0031] Preferably, the base 1 is disposed on the operating table 12.
[0032] Preferably, the diameter of the pipe 4 is the same as the diameter of the holes of the inlet end limiting block 2 and the outlet end limiting block 3. This ensures a tight fit between the pipe and the through hole of the limiting block, eliminating any wobbling or gaps in the pipe within the through hole, achieving precise positioning, ensuring that the cutting position matches the preset size, and avoiding cutting size deviations caused by positioning errors.
[0033] When using, such as Figure 4-6 As shown, the rotational speed of the lead screw 8 is adjusted according to the pipe conveying speed, causing the slider 7 to drive the cutting machine 5 to move synchronously along the slide rail 6, realizing dynamic following between the cutting device and the pipe. When the pipe is conveyed to the preset cutting position, the servo electric push rod 10 drives the cutting machine 5 to descend vertically and cut the pipe in the cutting area.
[0034] After cutting is completed, the servo electric push rod 10 drives the cutting machine 5 to rise, while the motor 9 drives the slider 7 to return to the initial position, ready for the next cut. The pipe continues to be conveyed, repeating the above actions to achieve automated cutting in continuous production.
[0035] This invention uses through holes in the inlet and outlet limit blocks to position the pipe. A servo electric push rod controls the lifting and lowering of the cutting machine, and a motor drives a lead screw to move the sliding device. This allows for automated cutting during continuous pipe transport without interrupting production. The limiting groove on the outlet side of the inlet limit block and the trumpet-shaped structure at the inlet end of the outlet limit block stabilize the pipe and facilitate its insertion. Furthermore, the limit blocks and grooves are detachably connected to accommodate pipes of different diameters. The base is mounted on the operating table to ensure device stability, thus enabling efficient, precise, and convenient cutting operations during continuous production.
[0036] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
