Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastics technology, and in particular to a device for removing burrs in the production of plastic products. Background Technology
[0002] Plastic products refer to products with specific shapes, sizes and uses made from plastic raw materials (such as resin) through various processing methods. Plastic is a material composed of synthetic or natural high molecular polymers, and its properties can be changed by adding various additives, such as enhancing flexibility, heat resistance, color and so on.
[0003] During the injection molding process of plastic water pipe fittings (such as elbows, tees, etc.), due to uneven material flow and differences in cooling rate, burrs or flash are easily generated on the inner ring. Although existing burr removal equipment has a good effect on removing burrs on the outer ring, its ability to remove burrs on the inner ring is limited. Even if the burrs on the inner ring can be partially removed, subsequent manual or mechanical grinding is still required to ensure the smoothness of the inner ring surface. This additional grinding process not only increases production costs but also significantly reduces production efficiency.
[0004] To address the aforementioned problems, there is a need for a burr removal device for plastic product manufacturing that can remove burrs from the inner ring of plastic water pipes. Utility Model Content

The base has first mounting plates symmetrically mounted on its left and right sides. Rollers are symmetrically rotatably connected between the two first mounting plates. A belt is wound between the right ends of the two rollers. A first motor is mounted on the right first mounting plate. The output shaft of the first motor passes through the first mounting plate and connects to the front roller. The base has symmetrically mounted first mounting plates on its left and right sides. It is said to be equipped with electric slide rails, with sliders slidably connected on both slide rails. A movable frame is connected between the two sliders, and a mounting frame is installed on the movable frame. A sliding frame is slidably connected to the mounting frame, and two second motors are installed on the sliding frame. The output shafts of the two second motors are connected to connecting rings, and mating rings are placed on the two connecting rings. Each mating ring has symmetrical front and rear threaded fixing screws. The two fixing screws are threaded with the connecting rings. A connecting shaft is placed inside the two connecting rings, and a grinding wheel is connected to the right side of the two connecting shafts. An electric telescopic rod is installed on the rear side of the movable frame, and the telescopic end of the electric telescopic rod is connected to the sliding frame.
[0007] Optionally, it also includes a connecting frame, a mounting frame, a vacuum cleaner motor, a barrier net, a telescopic tube, a second mounting plate, a vacuum suction pipe, and a collection frame. The connecting frame is connected to the movable frame, and the mounting frame is mounted on the connecting frame. The vacuum cleaner motor is installed inside the mounting frame, and the barrier net is installed inside the mounting frame. The telescopic tube is connected to the right side of the mounting frame. The second mounting plate is mounted on the sliding frame, and the vacuum suction pipe is mounted on the second mounting plate. The other end of the telescopic tube is connected to the vacuum suction pipe, and the collection frame is placed inside the mounting frame.
[0008] Optionally, it also includes a damping shaft, a connecting rod, a limiting frame, a first limiting block, and a second limiting block. The outer sides of the two first mounting plates are rotatably connected to the damping shaft, the two damping shafts are connected to the connecting rod, the two connecting rods are connected to the limiting frame, the outer sides of the two first mounting plates are connected to the first limiting block, and the outer sides of the two first mounting plates are connected to the second limiting block.
[0009] Optionally, it also includes connecting plates and first rollers. Multiple connecting plates are evenly spaced on the front side of the mounting frame, and each connecting plate is rotatably connected to the bottom of a first roller.
[0010] Optionally, it also includes a protective pad, with the protective pad connected inside the limiting frame.
[0011] Optionally, it also includes a second roller, with multiple second rollers evenly spaced at the bottom of the movable frame for rotational connection.
[0012] Optionally, it also includes an observation window, which is embedded in the front side of the collection frame.
[0013] Optionally, the shape of the internal grooves of the two connecting rings and the mating ring is consistent with that of the connecting shaft.
[0014] The beneficial effects of this utility model are as follows: 1. This device drives the plastic water pipe to rotate through a double roller system, and simultaneously grinds the outer and inner rings of the plastic water pipe with front and rear grinding wheels. The front grinding wheel is responsible for fine grinding of the outer ring, while the rear grinding wheel is specifically for deburring the middle part of the inner ring, ensuring that the inner and outer ring surfaces are smooth and burr-free, which greatly improves work efficiency and product quality. The electric slide rail drives the slider to move along the base, driving the moving frame and its components to run smoothly, realizing uniform grinding of the grinding wheels in the length direction of the water pipe. At the same time, the second motor synchronously drives the two grinding wheels to rotate, ensuring the consistency and efficiency of the deburring treatment of the inner and outer rings. In addition, the electric telescopic rod further pushes the sliding frame forward, allowing the grinding wheels to perform more detailed grinding on specific areas, thereby achieving precise grinding of complex shapes or areas with special requirements, further improving the quality of the final product. It not only solves the limitations of the existing technology in processing inner ring deburring, but also significantly improves the overall production efficiency and product quality.
[0015] 2. By setting the limit frame and connecting rod to rotate along the damping axis, the plastic water pipe can be limited during the grinding process to prevent the water pipe from moving and avoid uneven grinding or poor quality caused by instability.
[0016] 3. The vacuum cleaner motor, telescopic tube, and suction pipe are used to extract debris and dust generated during the polishing process in real time, preventing them from spreading into the air and causing pollution. The suction pipe guides the debris into the collection box inside the installation frame, and filters it through the barrier net, ensuring a clean working environment and the health of the operators.

A sliding frame 10 is slidably connected to the mounting frame 9. Two second motors 11 are installed on the sliding frame 10. The second motors 11 can drive the grinding wheel 16 to rotate. The output shafts of the two second motors 11 are connected to connecting rings 12. A docking ring 13 is placed on each of the two connecting rings 12. The upper part is symmetrically connected with fixing screws 14. Two fixing screws 14 are threadedly engaged with connecting rings 12. Connecting shafts 15 are placed inside each of the two connecting rings 12. The shape of the internal grooves of the two connecting rings 12 and the mating rings 13 is consistent with that of the connecting shafts 15. Grinding wheels 16 are connected to the right side of each of the two connecting shafts 15. The grinding wheel 16 on the front side can grind the outer ring of the plastic water pipe, and the grinding wheel 16 on the rear side can remove burrs from the inner ring of the plastic water pipe. An electric telescopic rod 17 is installed on the rear side of the moving frame 8. The telescopic end of the electric telescopic rod 17 is connected to the sliding frame 10. A connecting frame 18 is connected to the moving frame 8. A mounting frame 19 is installed on the connecting frame 18. A vacuum cleaner motor 20 is installed inside the mounting frame 19. The vacuum cleaner motor 20 can pick up debris. An obstruction net 21 is installed inside the mounting frame 19. A telescopic tube 22 is connected to the right side of the mounting frame 19.

Multiple second rollers 34 are evenly spaced at the bottom of the moving frame 8, allowing for easy movement. An observation window 35 is embedded on the front side of the collection frame 25 to facilitate observation of the debris collection inside.
[0028] When it is necessary to remove the rough edges of the plastic water pipe, the worker first places the plastic water pipe on two rollers 3. After the plastic water pipe is placed, the worker rotates the limiting frame 28 counterclockwise by 90 degrees. The limiting frame 28 drives the connecting rod 27 to rotate along the two damping shafts 26. After the rotation is completed, the first limiting block 29 will limit the connecting rod 27. Then the worker stops rotating the limiting frame 28. At this time, the limiting frame 28 will limit the plastic water pipe. Then, the worker places the two connecting shafts 15 into the grooves inside the two connecting rings 12. After the connecting shafts 15 are placed, the worker places the two mating rings 13 on the two connecting rings 12 and fixes the two connecting rings 12 and mating rings 13 with four fixing screws 14. This completes the installation of the two grinding wheels 16. Next, the operator starts the first motor 5. The output shaft of the first motor 5 drives the front roller 3 to rotate. The front roller 3, through the belt 4 connected to it, drives the rear roller 3 to rotate synchronously, thus rotating the plastic water pipe. Then, the operator starts the two second motors 11. The output shaft of the second motor 11 drives the connecting ring 12 to rotate, which in turn drives the two grinding wheels 16 to rotate. Subsequently, the vacuum cleaner motor 20 is started. The vacuum cleaner motor 20 transmits suction power to the telescopic tube 22 and the suction tube 24. Then, the two electric slide rails 6 are started. The electric slide rails 6 drive the slider 7 to slowly move to the rightmost end. The two sliders 7 drive the moving frame 8 and its components to move. When the moving frame 8 moves, the three first rollers... 32 and three second rollers 34 will roll on the base 1. Simultaneously, the front grinding wheel 16 grinds the outer ring of the rotating plastic water pipe during its movement, while the rear grinding wheel 16 removes burrs from the inner ring of the rotating plastic water pipe during its movement. The telescopic tube 22 will be extended, and the suction tube 24 will collect the debris from the front grinding wheel 16. The collected debris will flow through the telescopic tube 22 into the mounting frame 19 and be blocked by the barrier net 21. After the slider 7 has moved, if further grinding and deburring of the plastic water pipe is needed, the operator can activate the electric telescopic rod 17. The telescopic end of the electric telescopic rod 17 pushes the sliding frame 10 forward, allowing the two grinding wheels 16 to continue grinding and deburring the plastic water pipe. To remove burrs, after the two grinding wheels 16 have finished grinding and removing burrs from the plastic water pipe, the operator restarts the two electric slide rails 6. The electric slide rails 6 drive the slider 7 to move to the leftmost end, and then activate the electric telescopic rod 17 to retract it, so as to perform a second grinding and burr removal on the outer and inner rings of the plastic water pipe. The telescopic tube 22 will retract. After the slider 7 has finished moving and the electric telescopic rod 17 has retracted, the operator turns off the first motor 5, the second motor 11, and the vacuum cleaner motor 20. When the vacuum cleaner motor 20 stops emitting suction, the debris attached to the barrier net 21 will fall into the collection box 25. At this time, the operator pushes the limiting frame 28 and the connecting rod 27 to rotate 90 degrees clockwise along the damping shaft 26 to reset. After the limiting frame 28 has rotated,The plastic water pipes are no longer restricted; workers can now remove them directly.
