Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic pipe production technology, specifically to a port trimming machine for plastic pipe production. Background Technology
[0002] Plastic pipes are widely used in various fields due to their lightweight, corrosion resistance, and aesthetic appeal. Their main applications include water supply systems, drainage systems, gas transmission, electrical wiring, agricultural irrigation, and urban infrastructure. For ease of transportation, plastic pipes are typically cut into sections during production, usually by sawing. This cutting process easily produces burrs.

[0019] Please see Figure 1-3 This embodiment provides a technical solution: a port trimming machine for plastic pipe production, including a base 1;
[0020] Base 1: A movable seat 2 is slidably connected to its upper end. A support shaft 3 is rotatably connected to the upper end of the movable seat 2. An external conveying unit conveys the plastic tube to the left end of the support seat 4 and fixes it. After fixing, the axis of the plastic tube coincides with the axis of the support shaft 3. A support seat 4 is provided at the left end of the support shaft 3. A slide seat 6 is slidably connected to the rear end of the support seat 4. A chamfering cutter holder 7 is slidably connected to the upper end of the slide seat 6. An outer chamfering cutter 10 is provided on the rear side of the left end of the chamfering cutter holder 7, and an inner chamfering cutter 9 is provided on the front side of the left end of the chamfering cutter holder 7. The cutting edge of the outer chamfering cutter 10 is inclined to chamfer the outer arc surface of the tube opening. Similarly, the inner chamfering cutter 9 chamfers the inner arc wall of the tube opening. An end face cutting cutter holder 5 is slidably connected to the front end of the support seat 4. An end face cutting cutter holder 5 is provided at the left rear end of the end face cutting cutter holder 5. The lower surfaces of the face cutter 8, outer chamfering cutter 10, and inner chamfering cutter 9 are flush with the upper surface of the end face cutter 8 and at the same height as the axis of the support shaft 3. The support shaft 3 drives the slide 6, chamfering cutter holder 7, and end face cutting cutter holder 5 to rotate through the support base 4. The outer chamfering cutter 10, inner chamfering cutter 9, and end face cutter 8 rotate counterclockwise around the axis of the support shaft 3. The outer chamfering cutter 10, inner chamfering cutter 9, and end face cutter 8 move to the left simultaneously to contact and cut the plastic tube. The end face cutter 8 flattens the end of the plastic tube. A double-acting screw 13 is rotatably connected to the middle of the support base 4. The slide 6 and end face cutting cutter holder 5 are threaded to the double-acting screw 13. The front end of the double-acting screw 13 is provided with a hexagonal post 14, which can be connected to the hexagonal post 14 with a wrench to rotate the double-acting screw. Rod 13, a two-way lead screw 13, drives the slide 6 and the end-face cutting knife holder 5 to move closer or further apart, adjusting the distance between the outer chamfering knife 10, the inner chamfering knife 9, and the end-face knife 8 and the axis of the support shaft 3, facilitating the processing of plastic tubes of different diameters. A fine-tuning lead screw 15 is rotatably connected to the middle of the slide 6, and the fine-tuning lead screw 15 is threadedly connected to the middle of the chamfering knife holder 7. A hexagonal groove 16 is provided on the left end of the fine-tuning lead screw 15. Using an Allen wrench inserted into the hexagonal groove 16 to rotate the fine-tuning lead screw 15, the fine-tuning lead screw 15 drives the chamfering knife holder 7 to move laterally along the slide 6. The outer chamfering knife 10 and the inner chamfering knife 9 form a V-shaped cutting edge, which can change the size of the chamfer as it moves laterally, facilitating the processing of plastic tubes of different wall thicknesses. The upper left end of the moving seat 2 is equipped with... The protective shell 17 and the support base 4 are located inside the protective shell 17. The protective shell 17 provides protection for the rotating parts inside. The front end of the movable base 2 is equipped with a control switch group 12, which facilitates the control of electrical appliances. The input end of the control switch group 12 is electrically connected to an external power source. The middle of the upper surface of the base 1 is equipped with an electric push rod 11. The telescopic end of the electric push rod 11 is fixedly connected to the left end of the movable base 2. The input end of the electric push rod 11 is electrically connected to the output end of the control switch group 12. The telescopic end of the electric push rod 11 pushes the movable base 2 to slide to the left along the base 1. The upper surface of the right end of the movable base 2 is equipped with a motor 18. The output shaft of the motor 18 is equipped with a gear 19. The right end of the support shaft 3 is equipped with a gear 20. Gear 19 and gear 20 are meshed together.The input terminal of motor 18 is electrically connected to the output terminal of control switch group 12. The output shaft of motor 18 drives the support shaft 3 to rotate via gear 19 and gear 20. A protective shell 21 is provided on the right side of the upper end of the movable seat 2. Gear 19 and gear 20 are both located inside the protective shell 21, which provides protection for the internal components.
[0021] The working principle of the end trimming machine for plastic pipe production provided by this utility model is as follows: During use, the external conveying unit conveys the plastic pipe to the left end of the support base 4 and fixes it. After fixing, the axis of the plastic pipe coincides with the axis of the support shaft 3. The lower surfaces of the outer chamfering blade 10 and the inner chamfering blade 9 are flush with the upper surface of the end face blade 8 and at the same height as the axis of the support shaft 3. During operation, the control switch group 12, the electric push rod 11, and the motor 18 work. The output shaft of the motor 18 is connected to gear 19. Gear 20 drives the support shaft 3 to rotate. The support shaft 3, through the support seat 4, drives the slide 6, chamfering cutter seat 7, and end-face cutting cutter seat 5 to rotate. The outer chamfering cutter 10, inner chamfering cutter 9, and end-face cutting cutter 8 rotate counterclockwise around the axis of the support shaft 3. At the same time, the telescopic end of the electric push rod 11 pushes the moving seat 2 to slide to the left along the base 1. Consequently, the outer chamfering cutter 10, inner chamfering cutter 9, and end-face cutting cutter 8 move to the left simultaneously to contact and cut the plastic tube. The end-face cutting cutter 8 cuts the end of the plastic tube around its circumference. The outer chamfering cutter 10 is inclined to chamfer the outer arc surface of the pipe opening, and similarly, the inner chamfering cutter 9 chamfers the inner arc wall of the pipe opening. This provides a good finishing effect on the end of the plastic pipe, avoiding the generation of burrs. After finishing, the electric push rod 11 and motor 18 stop working. When the diameter of the plastic pipe changes, a wrench can be used to connect with the hexagonal column 14 to rotate the double-acting screw 13. The double-acting screw 13 drives the slide 6 and the end face cutting cutter holder 5 to move closer or further apart, thereby adjusting the outer chamfering cutter 1. 0. The distance between the inner chamfering cutter 9 and the end face cutter 8 and the axis of the support shaft 3 is adjusted to facilitate the processing of plastic pipes of different diameters. When it is necessary to change the chamfer size or the thickness of the pipe wall changes, an internal hex wrench can be inserted into the hexagonal groove 16 to rotate the fine adjustment screw 15. The fine adjustment screw 15 drives the chamfering cutter holder 7 to move laterally along the slide 6. The outer chamfering cutter 10 and the inner chamfering cutter 9 form a V-shaped cutting edge. As they move laterally, the size of the chamfer can be changed, which also facilitates the processing of plastic pipes with different wall thicknesses.
[0022] It is worth noting that the electric actuator 11 and motor 18 disclosed in the above embodiments can be freely configured according to the actual application scenario. The electric actuator 11 can be an ANT-52 electric actuator, and the motor 18 can be a YL80-2 single-phase motor. The control switch group 12 is equipped with switch buttons that correspond one-to-one with the electric actuator 11 and the motor 18 for controlling their switching operation.
