Description

Technical Field

[0001] This utility model relates to the field of plastic parts manufacturing technology, and more specifically, to a burr removal device for plastic parts manufacturing. Background Technology

[0002] During the manufacturing and processing of plastic parts, burrs often form on the edges, especially curved sides, due to factors such as mold closing clearance, fluctuations in injection molding process parameters, and differences in material flowability. These burrs not only affect the appearance quality of the plastic parts but may also lead to poor fit during assembly. Furthermore, burrs can detach during use, affecting the product's performance and safety. Therefore, effectively removing burrs from the curved sides of plastic parts is a crucial step in the plastic parts manufacturing process.

[0003] Currently, there are two main methods for removing burrs from the curved sides of plastic parts: manual grinding and mechanical grinding. Manual grinding typically involves operators using sandpaper, grinding heads, or files to manually grind the burrs according to the shape of the curved sides of the plastic part. While this method offers some flexibility and can adapt to curved sides with varying curvatures, it has significant drawbacks: firstly, manual grinding is extremely inefficient, making it difficult to meet the demands of large-scale production; secondly, the grinding quality heavily relies on the operator's skill level and experience, easily leading to over- or under-grinding.

[0004] However, for plastic parts with curved sides, mechanical grinding is difficult because the curvature of the side is constantly changing. The fixed-shaped grinding wheel or grinding belt is difficult to maintain good contact with the curved side at all times, resulting in uneven grinding. Burrs in some places cannot be completely removed. At the same time, the unstable contact pressure may also cause scratches or excessive grinding on the surface of the plastic part, affecting the product precision. Utility Model Content

[0005] The main objective of this invention is to provide a burr removal device for plastic parts production, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

Two connecting pipes are fixedly connected to the middle of the right end of the dust collection box. A suction nozzle is fixedly installed on the right side of each of the two connecting pipes. The suction nozzles are fixedly connected to the two sides of the right end of the movable rod, respectively.

At the same time, it avoids pollution to the working environment. Attached Figure Description

Detailed Implementation

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] As attached Figure 1 To be continued Figure 5 As shown, an embodiment of this utility model provides a burr removal device for plastic parts production, including a rotary clamping device 1, an adjusting device 2, a burr removal component 3, and a dust removal device 4. The side of the rotary clamping device 1 is fixedly installed with the adjusting device 2, the burr removal component 3 is slidably installed on the top of the adjusting device 2, and the dust removal device 4 is disposed inside the adjusting device 2.

[0025] As attached Figure 4 As shown, the burr removal assembly 3 includes a lifting block 31, a buffer spring 38, and a grinding roller 36. Limiting blocks 32 are fixedly installed on both sides of the lifting block 31. A pressure sensor 33 is fixedly installed on the left side of the lifting block 31. A movable rod 34 is movably sleeved on the right side of the lifting block 31. A grinding motor 35 is fixedly installed on the top of the right end of the movable rod 34. The output end of the grinding motor 35 is fixedly installed with the grinding roller 36. The grinding roller 36 is rotatably installed at the bottom of the movable rod 34. A pressing block 37 is fixedly installed on the left side of the movable rod 34. The pressing block 37 is movably sleeved inside the lifting block 31. The buffer spring 38 is located between the lifting block 31 and the pressing block 37.

[0026] By setting a buffer spring 38, the grinding roller 36 is made to fit against the side of the plastic part and move along the shape of the plastic part when the plastic part rotates, thus removing the burrs on the side of the plastic part and improving the burr removal effect.

[0027] like Figure 3 The adjusting device 2 includes a second base 21 and a fixed rail 24. A side plate 22 is fixedly installed on the top of the second base 21. The fixed rail 24 is fixedly installed on both ends of the right side of the top of the second base 21. Push cylinders 23 are fixedly installed on both ends of the left side of the side plate 22. A sliding base 25 is slidably installed on the outer surface of the fixed rail 24 at both ends. A support frame 26 is fixedly installed on the top of the sliding base 25. A height adjusting cylinder 27 is fixedly installed on the top of the support frame 26. Limit rods 28 are fixedly installed on both sides inside the support frame 26. The output end of the push cylinder 23 is connected to the side of the sliding base 25.

[0028] The lifting block 31 is slidably installed inside the support frame 26, the limiting block 32 is movably sleeved on the outer surface of the limiting rod 28, and the bottom of the height adjusting cylinder 27 is fixedly connected to the top of the lifting block 31.

[0029] The height adjustment cylinder 27 controls the burr removal assembly 3 to rise and fall inside the support frame 26, thereby enabling the grinding roller 36 to adapt to plastic parts of different heights and thicknesses. Through the interaction of the push cylinder 23 and the pressure sensor 33, when the side of the plastic part is long, the side of the plastic part is pressed against the outer surface of the grinding roller 36, causing the movable rod 34 to retract into the interior of the lifting block 31, and the pressing block 37 to press against the side of the pressure sensor 33. The pressure sensor 33 controls the push cylinder 23 to retract, causing the sliding base 25 to move to the left side of the outer surface of the fixed track 24, avoiding the plastic part being too long and affecting the grinding of the grinding roller 36. Thus, the burr removal assembly 3 can remove burrs from the edges of plastic parts with large shapes.

[0030] like Figure 5 As shown, the dust removal device 4 includes a dust collection box 41 and a suction nozzle 43. The dust collection box 41 is fixedly installed at the bottom of the sliding base 25. Two connecting pipes 42 are fixedly connected to the middle of the right end of the dust collection box 41. The right sides of the connecting pipes 42 at both ends are fixedly installed with the suction nozzles 43. The suction nozzles 43 at both ends are fixedly connected to the two sides of the right end of the movable rod 34 respectively. A dust collection box 47 is movably sleeved at the lower end of the middle of the dust collection box 41. Filter screens 44 are fixedly connected to both sides of the upper end of the dust collection box 41. Exhaust vents 45 are opened at both ends of the left side of the dust collection box 41. A vacuum cleaner 46 is fixedly connected to the side of the exhaust vent 45.

[0031] The dust suction nozzle 43 suctions dust from both sides of the grinding roller 36, and the grinding roller 36 removes dust from the sides of the plastic parts. This prevents burrs and debris from being attracted to the sides of the plastic parts by static electricity, which would affect the removal of burrs from the edges of the plastic parts by the grinding roller 36. At the same time, it avoids pollution to the working environment.

[0032] like Figure 2 As shown, the rotating clamping device 1 includes a first base 11, a fixed frame 12 is fixedly installed on the top of the first base 11, a lifting cylinder 13 is fixedly installed on the top of the fixed frame 12, a lifting frame 14 is fixedly installed at the output end of the lifting cylinder 13, a rotary motor 15 is fixedly installed at the upper end of the lifting frame 14, a clamping plate 16 is fixedly installed at the output end of the rotary motor 15, the clamping plate 16 is rotatably installed at the bottom of the lifting frame 14, and a rotating base plate 17 is rotatably installed on the top of the first base 11, the rotating base plate 17 being located below the clamping plate 16.

[0033] The plastic part is placed on top of the rotating base plate 17. The lifting cylinder 13 controls the lifting frame 14 to descend, so that the clamping plate 16 and the rotating base plate 17 clamp the plastic part. The rotating motor 15 controls the plastic part inside the clamping plate 16 and the rotating base plate 17 to rotate, so that the grinding roller 36 can remove the side burrs of the plastic part.

[0034] The working process of this utility model is as follows:

[0035] In use, the plastic part is placed on top of the rotating base plate 17. The lifting cylinder 13 controls the lifting frame 14 to descend, so that the clamping plate 16 and the rotating base plate 17 clamp the plastic part. The height adjustment cylinder 27 controls the burr removal assembly 3 to rise and fall inside the support frame 26, so that the grinding roller 36 is located on the side of the plastic part. The pushing cylinder 23 controls the sliding base 25 to move to the right side of the outer surface of the fixed track 24, so that the grinding roller 36 is in contact with the side of the plastic part. Then, the rotary motor 15 controls the clamping plate 16 to rotate, so that the plastic part inside the clamping plate 16 and the rotating base plate 17 rotates. At the same time, the grinding motor 35 controls the grinding roller 36 to rotate, so as to grind the side of the plastic part. Through the action of the buffer spring 38, the grinding roller 36 is in contact with the side of the plastic part, and the grinding roller 36 moves along the shape of the plastic part.

[0036] When the side of the plastic part is long, the side of the plastic part is pressed against the outer surface of the grinding roller 36, causing the movable rod 34 to retract into the interior of the lifting block 31. The pressing block 37 presses against the side of the pressure sensor 33, and the pressure sensor 33 controls the push cylinder 23 to retract, causing the sliding base 25 to move to the left on the outer surface of the fixed track 24. The pressure sensor 33 senses the grinding pressure of the grinding roller 36 and senses a certain threshold. When the pressure of the plastic part pressing on the grinding roller 36 exceeds or falls below the pressure threshold, the push cylinder 23 controls the sliding base 25 to move on the outer surface of the fixed track 24, thereby adjusting the grinding roller 36 to move according to the shape of the plastic part.

[0037] In addition, the vacuum cleaner 46 operates, and the vacuum nozzle 43 sucks up the dust from the polished burrs. The dust enters the dust collection box 41 through the vacuum nozzle 43 and the connecting pipe 42, and is intercepted by the filter screen 44, causing the dust to fall into the dust collection box 47, thus achieving cleaning during burr removal.

[0038] Finally, it should be noted that: the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
