For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] like Figure 1-4 As shown, the present invention provides an automatic cleaning device for outer diameter burrs of plastic products, comprising: a base 1, on which a reduction motor 2 is arranged, the reduction motor 2 is integrated with a servo motor and a reducer, and its output shaft extends upward perpendicular to the surface of the base 1; a profiling positioning block 3 is arranged on the top of the reduction motor 2, the bottom of the profiling positioning block 3 is matched with the output shaft of the reduction motor 2 and can rotate with it, the shape of the profiling positioning block is adapted to the inner surface shape of the plastic product, and is used to locate the position of the plastic product to avoid the phenomenon that the product seriously deviates from the axis during the rotation process, and can rotate with the reduction motor 2; a pressing mechanism 4 is arranged above the profiling positioning block 3. The pressing mechanism 4 can press the top of the plastic product after it is positioned by the profiling positioning block 3, so as to avoid the product slipping during rotation and ensure that the plastic product can stably rotate around the output shaft of the reduction motor 2 during the burr removal process; a deburring mechanism is arranged on one side of the profiling positioning block 3, which includes a moving seat 5, a tool holder cylinder 6 and a tool holder 7 are installed at the front end of the moving seat 5, and a blade 8 is installed at the front end of the tool holder 7. The blade 8 can be attached to the surface of the plastic product under the action of the tool holder cylinder 6, and the burrs on the outer diameter edge of the plastic product can be cleaned in coordination with the rotation of the plastic product. After the burr cleaning is completed, the tool holder cylinder 6 drives the tool holder 7 to be recovered, and the reduction motor 2 stops rotating. Through the above-mentioned structural coordination, the process of removing the outer diameter burrs of the plastic product is automated, the product appearance quality is improved, and the labor intensity of the operator is reduced.

[0033] The pressing mechanism 4 includes a rotating pressing cylinder 401, a rotating rod 402 and a pressing head 403, wherein the bottom of the rotating pressing cylinder 401 is fixedly connected to the side or edge of the profiling positioning block 3, and its top is at least 10 cm higher than the surface of the profiling positioning block 3, one end of the rotating rod 402 is connected to the end of the push rod of the rotating pressing cylinder 401, and the pressing head 403 is connected to the other end of the rotating rod 402, and the pressing head 403 extends downward, and the rotating rod 402 can be rotated to the top of the profiling positioning block 3 or moved away from the top thereof by the rotation of the rotating pressing cylinder 401, so that the plastic product can be positioned on the profiling positioning block 3 conveniently. After the plastic product is positioned, the pressing head 403 is rotated to the top thereof and moves downward under the drive of the rotating pressing cylinder 401 to press on the surface of the plastic product. The pressing head 403 is a flexible pressing head to avoid damaging the surface of the plastic product. There are two sets of pressing mechanisms 4, which can be used in combination to ensure that the plastic product is pressed tightly when cleaning burrs, thereby avoiding scratches on the product surface due to unstable rotation.

[0034] Furthermore, two parallel dovetail grooves 9 are provided on the surface of the base 1, and the dovetail grooves 9 are set from the edge of the base toward the contour positioning block 3. The bottom of the movable seat 5 is provided with a slider 10 that slides in accordance with the dovetail groove 9. By cooperating with the slider 10 and the dovetail groove 9, the position of the movable seat 5 on the base 1 can be adjusted to make it close to the contour positioning block 3. Both ends of the movable seat 5 are provided with connecting blocks 11 that are integrated therewith, and tightening screws 12 are installed on the connecting blocks 11. By tightening the tightening screws 12, it can be tightened with the base 1 to fix the position of the movable seat 5.

[0035] In this embodiment, the tool holder 7 is installed at the front end of two guide rods 13, and the front end of the guide rods 13 is sleeved with a spring 14, and the rear ends of the two guide rods 13 pass through the movable seat 5 horizontally. When the blade 8 presses against the outer periphery of the plastic product, the spring 14 is in a compressed state. The front end of the tool holder cylinder 6 is L-shaped and can be stuck on the side of the tool holder 7 away from the spring 14. When the movable seat 5 moves to a position close to the contour positioning block 3, the tool holder cylinder 6 is extended, and the tool holder 7 can be extended under the rebound effect of the spring 14, so that the blade 8 presses against the outer diameter of the burr to be cleaned on the outer periphery of the plastic product. The cutting force of the blade 8 can be guaranteed by the spring 14, thereby removing the burr.

[0036] In this embodiment, an adjusting rod 15 is mounted on the outer side of the guide rod 13, and an outer thread is provided on the outer periphery of the adjusting rod 15 to be threadedly connected with the moving seat 5, and a ball is provided between the inner wall of the adjusting rod 15 and the outer periphery of the guide rod 13. By rotating the adjusting rod 15, one end of the adjusting rod 15 can be extended from the front end of the moving seat 5, and the end of the spring 14 is pressed against the end face of the adjusting rod 15. The adjusting rod 15 is screwed toward the side close to the tool holder 7 to adjust the compression of the spring 14, so as to achieve the effect of adjusting the cutting force of the blade 8. By providing the ball, when the adjusting rod 15 is rotated, the guide rod 13 can be prevented from shaking or generating a large friction force with the inner wall of the adjusting rod 15, thereby affecting the position of the tool holder 7. The front end of the guide rod 13 is embedded with the tool holder 7 or connected by thread, so that the tool holder 7 can be conveniently installed and disassembled as a whole, and the position of the blade 8 on the tool holder 7 can be adjusted, so that the position of the blade 8 can be fine-tuned after the moving seat 5 is moved into place.

[0037] The base 1 is also provided with a start / stop button 16, which can control the rotation and pressing cylinder 401 to press the product and the start / stop of the reduction motor 2, so as to automatically clean the burrs. The side of the base 1 is provided with an external signal port 17, which is convenient for connecting an external robot arm to carry out the plastic product picking and placing operation, realize the automation of the production line, and improve the production efficiency.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
