Description

Technical Field

[0001] This utility model relates to the field of toilet seat production equipment, specifically to an automatic deburring device for toilet seat plates. Background Technology

[0002] During the injection molding process of toilet seats and toilet rings, plastic burrs inevitably remain at the edges due to various factors, including the flow characteristics of the molten plastic within the mold cavity, the manufacturing precision of the mold, and the injection molding process parameters. These burrs not only make the surface of the seat uneven and unsightly, affecting its appearance and user experience, but may also impact the product's functionality and lifespan. Therefore, after molding, the burrs must be removed to ensure the product meets quality standards.

[0003] Currently, common flash removal equipment on the market typically uses rotating grinding wheels or heads to abrade and polish the edges of cover plates to remove flash. However, a significant problem with existing equipment during the flash removal process is the potential for plastic flash to splatter. Due to the high-speed friction between the grinding device and the plastic flash, the flash can be ejected as small particles or fragments. This splattered plastic flash not only pollutes the working environment and increases the difficulty and cost of cleanup, but it can also pose health risks to operators. For example, splattered plastic particles entering the eyes or respiratory tract can cause eye damage and respiratory illnesses. Furthermore, the splattered plastic flash can damage the equipment itself, affecting its normal operation and lifespan.

[0004] In view of the above-mentioned problems with existing deburring equipment, it is necessary to develop an automatic deburring equipment for cover plates that can effectively remove plastic burrs while collecting and crushing them, avoiding burr splattering, thereby improving the working environment, protecting the health of operators, and improving the reliability and stability of the equipment.

The axis of the third crushing column is on the same straight line as the axis of the corresponding second crushing column.

[0015] The output end of the rotary drive mechanism is connected to one of the crushing rods. The rotary drive mechanism is used to drive one of the crushing rods to rotate, thereby driving the remaining crushing rods to rotate in the same direction.

[0016] Furthermore, the aforementioned frame also includes a chip collection hopper in the shape of an inverted frustum or an inverted pyramid. The volume of the crushing chamber is smaller than that of the grinding chamber. The chip collection hopper is located between the grinding chamber and the crushing chamber and is used to guide the flash and dust in the grinding chamber into the crushing chamber.

Then, the grinding device is started to grind and remove the burrs from the edges of the cover plate on the positioning fixture. At the same time, the rotary drive mechanism is started, which drives the crushing rod to rotate at high speed. At this time, the plastic burrs and dust generated by grinding in the grinding chamber will automatically fall into the crushing chamber under the action of gravity and be crushed into fine particles by the high-speed rotating crushing rod. These crushed burrs and dust will form an orderly flow under the continuous rotation of the crushing rod, and be carried in and concentrated at the bottom or lower area of ​​the crushing chamber, realizing an integrated process of burr removal, burr crushing and waste collection. As can be seen, this invention effectively removes burrs from cover plates through the combination of a grinding device and a positioning fixture. While removing burrs, the grinding chamber effectively intercepts flying burrs and dust, preventing them from escaping and thus avoiding pollution of the working environment and potential harm to operators. Furthermore, the crushing chamber and crushing device promptly crush and collect burrs, making the work site cleaner and more orderly. In addition, the rotating crushing rod in this invention has an extra protective function, acting as a dynamic barrier to effectively prevent burrs below the crushing chamber from flying out again, further enhancing the reliability and stability of the equipment.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] This utility model provides an automatic burr removal device for cover plates, which solves the problem of how to collect and crush burrs while removing them from cover plates 5, thus avoiding burrs from splashing.

[0036] See Figure 1 , Figure 3 and Figure 4 As shown, Figure 1 This is a perspective view of the automatic deflash removal device for the cover plate in the embodiment. Figure 3 This is a top view of the frame, positioning fixture, and crushing device in the embodiment. Figure 4 The diagram shows the structure of the crushing chamber and crushing device in the embodiment. The automatic deburring equipment for the cover plate includes a frame 1, a positioning fixture 2, a grinding device 3, and a crushing device 4.

[0037] The frame 1 includes a grinding chamber 11 and a crushing chamber 12. The crushing chamber 12 is located below the grinding chamber 11 and is connected to the grinding chamber 11.

[0038] Positioning fixture 2 is installed inside the grinding chamber 11. Positioning fixture 2 is used to support and position the cover plate 5 to be processed.

[0039] The grinding device 3 is installed on the frame 1 and is used to grind the edge of the cover plate 5 on the positioning fixture 2 to remove burrs.

[0040] The crushing device 4 includes a crushing rotor 41 and a rotary drive mechanism 42. The crushing rotor 41 is rotatably connected inside the crushing chamber 12. The rotary drive mechanism 42 is located outside the crushing chamber 12 by means of screwing or welding, and is connected to the crushing rotor 41 for transmission. The rotary drive mechanism 42 is used to drive the crushing rotor 41 to rotate, thereby crushing the plastic flash that falls into the crushing chamber 12.

[0041] When using the automatic burr removal equipment for cover plates described above, firstly, the cover plate 5 to be processed is placed and fixed on the positioning fixture 2. Then, the grinding device 3 is started to grind and remove the burrs from the edges of the cover plate 5 on the positioning fixture 2. At the same time, the rotary drive mechanism 42 is started, which drives the crushing rod 41 to rotate at high speed. At this time, the plastic burrs and dust generated by grinding in the grinding chamber 11 will automatically fall into the crushing chamber 12 under the action of gravity, and be crushed into fine particles by the high-speed rotating crushing rod 41. These crushed burrs and dust will form an orderly flow under the continuous rotation of the crushing rod 41, and be carried in and concentrated in the bottom or lower area of ​​the crushing chamber 12, realizing an integrated process of burr removal, burr crushing and waste collection. It can be seen that this utility model can effectively remove the burrs from the cover plate 5 by combining the grinding device 3 and the positioning fixture 2. While removing burrs, this invention effectively intercepts flying burrs and dust through the grinding chamber 11, preventing them from escaping and thus avoiding pollution of the working environment and potential harm to operators. Furthermore, the pulverizing chamber 12 and pulverizing device 4 can promptly pulverize and collect burrs, making the work site cleaner and more orderly.

[0042] In addition, the rotating crushing rod 41 in this invention also has an additional protective function, acting as a dynamic barrier to effectively prevent the burrs below the crushing chamber 12 from flying out again, further enhancing the reliability and stability of the equipment.

[0043] The aforementioned rotary drive mechanism 42 can be an existing rotary motor or servo motor, etc., and is connected to the crushing rotor 41 via a transmission component such as a belt / gear.

[0044] The aforementioned grinding device 3 can be composed of an existing rotatable grinding wheel / grinding head 31 and a robotic arm / three-axis moving mechanism 32. The robotic arm / three-axis moving mechanism 32 can drive the grinding wheel / grinding head 31 to move relative to the positioning fixture 2 in the transverse, longitudinal, and / or vertical directions, so that the rotatable grinding wheel / grinding head 31 can grind any edge of the cover plate 5 to remove burrs, effectively removing burrs from the cover plate 5. In this embodiment, the grinding device 3 is composed of a grinding head 31 and a three-axis moving mechanism 32, such as... Figure 1 As shown.

[0045] See Figure 4 As shown, in one embodiment of the crushing rotor 41, the crushing rotor 41 includes a shaft 411 and a plurality of first crushing columns 412. The shaft 411 is rotatably connected to the crushing chamber 12, and the plurality of first crushing columns 412 are uniformly fixed to the outer surface of the shaft 411 by welding or integral connection. The inner walls of both sides of the crushing chamber 12 are provided with a plurality of second crushing columns 121 by welding or integral connection. The plurality of second crushing columns 121 are arranged at equal intervals along the axis of the shaft 411. The second crushing columns 121 are located between two adjacent first crushing columns 412. Thus, the uniformly distributed first crushing columns 412 on the crushing rotor 41 cooperate with the second crushing columns 121 on the inner wall of the crushing chamber 12, increasing the opportunities for collision and shearing of plastic flash, and improving crushing efficiency and effect.

[0046] See Figure 4 As shown, based on the above embodiment, there are at least two crushing rotors 41. The crushing rotors 41 are arranged at equal intervals. Adjacent crushing rotors 41 are connected by a belt or gear, and a fixed crushing rod 13 is provided between adjacent crushing rotors 41. The fixed crushing rod 13 is fixed within the crushing chamber 12 by welding or integral connection. Multiple third crushing columns 131, corresponding one-to-one with the positions of the second crushing columns 121, are provided on both sides of the fixed crushing rod 13 by welding or integral connection. The axis of the third crushing column 131 is aligned with the axis of the corresponding second crushing column 121. The output end of the rotary drive mechanism 42 is connected to one of the crushing rotors 41. The rotary drive mechanism 42 drives one of the crushing rotors 41 to rotate, thereby causing the remaining crushing rotors 41 to rotate in the same direction. Thus, at least two synchronously rotating crushing rotors 41 cooperate with the fixed crushing rod 13 to further refine the crushing space, enhance the crushing effect, and make the burrs finer.

[0047] See Figure 1 and Figure 3As shown, based on any of the above embodiments, the frame 1 further includes a chip collection hopper 14 in the shape of an inverted frustum or an inverted truncated cone. The volume of the pulverizing chamber 12 is smaller than that of the grinding chamber 11. The chip collection hopper 14 is disposed between the grinding chamber 11 and the pulverizing chamber 12 by means of welding or integral connection, and is used to guide the flash and dust in the grinding chamber 11 into the pulverizing chamber 12. The grinding chamber 11 is formed by a plurality of vertically arranged anti-splash plates 111. The anti-splash plates 111 are fixed to the top of the chip collection hopper 14 by means of welding or screw connection. In this way, the chip collection hopper 14, which is in the shape of an inverted frustum or an inverted truncated cone, can better guide the flash and dust in the grinding chamber 11 into the pulverizing chamber 12 and prevent splashing; while the anti-splash plates 111 enclosing the grinding chamber 11 can effectively intercept the splashed flash and dust without interfering with the flash removal of the grinding device 3, and prevent the flash and dust from overflowing. The crushing chamber 12 has a smaller volume than the grinding chamber 11, which makes reasonable use of space and ensures that the crushing device 4 can effectively handle the burrs.

[0048] See Figure 1 and Figure 3 As shown, based on any of the above embodiments, there are at least two positioning fixtures 2. Thus, by setting at least two positioning fixtures 2, multiple cover plates 5 can be positioned simultaneously. Combined with the grinding device 3, batch deburring processing can be performed, greatly improving production efficiency and shortening the production cycle.

[0049] See Figure 1 and Figure 3 As shown, in one embodiment of the positioning fixture 2, the positioning fixture 2 includes a placement frame 21, a first positioning component 22, and a second positioning component 23. The placement frame 21, the first positioning component 22, and the second positioning component 23 are all installed inside the grinding chamber 11. The placement frame 21 is used to support the cover plate 5. The first positioning component 22 and the second positioning component 23 are both located outside the placement frame 21. Specifically, when the grinding device 3 grinds the transverse edges of the cover plate 5 to remove burrs, the first positioning component 22 is used to fix the longitudinal edges of the cover plate 5; when the grinding device 3 grinds the longitudinal edges of the cover plate 5 to remove burrs, the second positioning component 23 is used to fix the transverse edges of the cover plate 5. Thus, during the grinding process, the positioning fixture 2 alternately positions the cover plate 5 according to the grinding trajectory using the first positioning component 22 and the second positioning component 23. This effectively avoids interference between the positioning fixture 2 and the grinding device 3, and ensures that the position of the cover plate 5 does not shift during the grinding process, thereby ensuring the stability of the cover plate 5 during grinding and improving the accuracy and quality of burr removal.

[0050] See Figure 2 As shown, Figure 2 for Figure 1The enlarged schematic diagram at point A shows that, in one embodiment of the first positioning component 22 and the second positioning component 23, both the first positioning component 22 and the second positioning component 23 include a first clamping arm 24, a first clamping arm drive 25, a second clamping arm 26, and a second clamping arm drive 27. The first clamping arm 24 and the second clamping arm 26 are positioned opposite each other on the outer sides of the placement frame 21. The first clamping arm drive 25 and the second clamping arm drive 27 are both mounted on the frame 1 by welding or screwing. The first clamping arm drive 25 is driven to the first clamping arm 24 and is used to drive the first clamping arm 24 to move up and down, or to drive the first clamping arm 24 to translate towards or away from the placement frame 21. The second clamping arm drive 27 is driven to the second clamping arm 26 and is used to drive the second clamping arm 26 to translate towards or away from the first clamping arm 24. Thus, the first clamping arm drive 25 drives the first clamping arm 24 to move up and down or translate, and the second clamping arm drive 27 drives the second clamping arm 26 to translate toward or away from the first clamping arm 24 to clamp or release the cover plate 5. This flexible driving method can accurately position the cover plate 5 according to its actual size and shape, improving the accuracy and adaptability of the positioning.

[0051] The first clamping arm drive 25 and the second clamping arm drive 27 can both use existing linear drive mechanisms such as telescopic cylinders or telescopic poles. The output end of the first clamping arm drive 25 is connected to the first clamping arm 24 by means of screwing or welding, and the output end of the second clamping arm drive 27 is connected to the second clamping arm 26 by means of screwing or welding.

[0052] The first clamping arm 24 and the second clamping arm 26 can be designed into V-shapes, concave shapes, etc., according to the shape of the cover plate 5, so as to stably position the cover plate 5. The first clamping arm 24 of each positioning fixture 2 can be the same, and the second clamping arm 26 can be the same, so as to be suitable for positioning cover plates 5 of the same shape and specification. Alternatively, the first clamping arm 24 of each positioning fixture 2 can be different, and the second clamping arm 26 can also be different, so as to be suitable for positioning cover plates 5 of different shapes and specifications.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
