Description

Technical Field

[0001] This invention relates to the field of plastic product processing technology, and in particular to a deburring device for processing plastic products. Background Technology

[0002] Plastic products are a general term for everyday and industrial goods made primarily from plastics; including products manufactured using all processes such as injection molding and thermoforming. Plastics are a class of malleable synthetic polymers; together with synthetic rubber and synthetic fibers, they form the three essential synthetic materials for daily life. Specifically, plastics are materials made primarily of natural or synthetic resins, with various additives, which can be molded into specific shapes under certain temperature and pressure conditions and retain their shape at room temperature.

[0003] After processing plastic products, such as the inner wall of plastic gears, a lot of burrs are still generated. At this time, deburring equipment is needed. There are many types of deburring equipment, and not every piece of equipment can be used for processing plastic products. Existing deburring equipment includes magnetic grinding machines (magnetic polishing machines), vibratory grinding machines, centrifugal grinding machines, flow finishing machines, robotic deburring, chemical deburring, electrolytic deburring, etc. Generally, for the processing of metal or plastic products, mechanical deburring methods are used, including the use of industrial robots in FMS (Factory Management System). The robot holds a wire brush or grinding wheel to grind the burrs. The grinding work is placed on a tool storage rack, and the robot can automatically change grinding tools according to different parts and deburring needs. In many cases, general-purpose robots are not ideal deburring equipment because the rigidity and precision of the robot's articulated arms are insufficient, and many parts require different deburring methods for different parts.

[0004] During the implementation of the above technical solution, at least the following technical problems were found:

[0005] Traditional deburring equipment typically uses grinding wheels to process workpieces. The angle of the grinding wheel is adjusted, and the workpiece is fixed one-to-one with a clamp before grinding or deburring. During deburring, a significant amount of dust or waste is generated, which can be removed using an air pump. However, the suction power of the air pump usually weakens significantly after a period of use, mainly because waste clogs the filter screen inside the pump, causing blockage and affecting the suction effect. After deburring a workpiece, manual adjustment of the clamping tools is required before proceeding with the next workpiece, further impacting the overall efficiency of the deburring operation. Summary of the Invention

[0006] Technical problems to be solved:

[0007] To address the shortcomings of existing technologies, this invention provides a deburring device for processing plastic products. By using an adjusting component and an equipped collection cylinder, the device can simultaneously perform two operations using a vacuum pump inside the collection cylinder: collecting waste material and adjusting the clamping block at the top of the adjusting component. This ensures that the workpiece is tightly fixed to the clamping block during the deburring operation, enabling batch processing of workpieces and thus improving work efficiency. Furthermore, the filter screen inside the collection cylinder prevents the problem of weakened suction effect.

[0008] Technical solution:

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] A deburring device for processing plastic products includes three parts: an adjustment component, a deburring component, and a collection cylinder.

[0011] The adjustment assembly is used to grip the workpiece to be processed placed on the conveyor belt;

[0012] The deburring component is located on one side of the adjustment component and acts on the surface of the workpiece. It is the core structure of the entire equipment and is used to remove burrs from the workpiece.

[0013] The collection cylinder is installed on one side of the adjustment component, and the inside of the collection cylinder is under negative pressure, corresponding to the position of the workpiece in the deburring state. This collection cylinder is used to collect waste material.

[0014] The adjusting component is detachably equipped with a top rod, and several clamping blocks arranged in a ring are installed at the end of the top rod. Each clamping block is connected to the other by a bladder. The air pump at the bottom of the collecting cylinder is connected to the bladder, and an elastic element is installed in the bladder. When deburring the workpiece, the outer side of the clamping block abuts against the inner wall of the workpiece.

[0015] In one possible implementation, the regulating component includes:

[0016] The system includes a bracket, a drive motor, and a cylinder. The drive motor is mounted on the bottom side of the bracket. The cylinder is located above the bracket and is connected to the output shaft of the drive motor. The piston rod of the cylinder is helically connected to the push rod. The bladder is fixed to the end of the push rod. The elastic element is used to connect the center position of the bladder and the various arc-shaped clamping blocks.

[0017] In one possible implementation, the deburring assembly includes: a base frame, a slanted support platform, and a tool holder; the slanted support platform is fixedly mounted on the top of the base frame; the tool holder is movably mounted on the track of the slanted support platform, and bolts for positioning the tool holder are provided on the surface of the slanted support platform; a blade is detachably mounted on the surface of the tool holder, and the blade is used to remove the surface of the workpiece, and an abrasive is inserted at the end corner of the blade, the abrasive contacting the inner wall edge of the workpiece.

[0018] The grinding element includes a movable plate and a slicing assembly disposed on the right-angle end of the movable plate. An insert is integrally welded onto the movable plate, and the grinding element is connected to the blade by the insert through a notch. The slicing assembly includes a transverse plate and a longitudinal plate, and both the transverse plate and the longitudinal plate are connected to the movable plate by a rotating shaft equipped with a torsion spring.

[0019] In one possible implementation, the collecting cylinder and the support are connected by a connecting plate, and a suction pump is spirally mounted at the bottom of the collecting cylinder. The suction pump and the bladder are connected by a retractable air pipe. An electrically controlled valve is installed on the outer wall of the suction pump, and the electrically controlled valve is used to switch the air inlet pipe on and off. A filter screen is provided inside the collecting cylinder, and the filter screen is always located directly above the suction pump. The filter screen has an L-shaped cross-section, and the edge of the filter screen has an arc-shaped frame mesh at the same height as the suction pump.

[0020] Beneficial effects:

[0021] Firstly, in this solution, the adjustment component and the collection cylinder are combined. The air pump at the bottom of the collection cylinder can collect the waste generated during the deburring operation. At the same time, it can also drive the corresponding clamping block to move to clamp and release the corresponding workpiece, ensuring that the workpiece can be processed in batches. This improves the efficiency of the entire deburring operation and solves the problem that traditional deburring equipment can only deburr a single plastic product at a time.

[0022] Secondly, in this solution, a collection cylinder is designed at the deburring station. The suction force generated by the air pump can be used to collect the waste. Since a filter screen is set in the collection cylinder, the problem of excessive waste in the collection cylinder causing the filter screen to become clogged and the air pumping work to be unable to proceed smoothly can be avoided. This ensures that the waste collection work can be carried out continuously and solves the problem of waste splashing and inconvenience in cleaning during the operation of traditional deburring equipment.

[0032] This application provides a deburring device for processing plastic products. By using an adjustment component and an equipped collection cylinder, the device can simultaneously perform two operations using a vacuum pump inside the collection cylinder: one is the collection of waste material, and the other is the adjustment of the clamping block at the top of the adjustment component. This ensures that the workpiece is tightly fixed to the clamping block during the deburring operation, enabling batch processing of workpieces and thus improving work efficiency. Furthermore, the filter screen inside the collection cylinder avoids the problem of weakened suction effect.

[0033] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0034] Example 1:

[0035] This embodiment describes the specific structure of the adjustment component and its related parts in a deburring device for processing plastic products, such as... Figures 1-5 As shown, the adjustment component 1 is used to clamp the workpiece 9 to be processed placed on the conveyor belt 4;

[0036] In some examples, the adjusting assembly 1 is detachably equipped with a push rod 8, and a number of clamping blocks 11 arranged in a ring are installed at the end of the push rod 8. The clamping blocks 11 are connected to each other by a bladder 10. The air pump 18 at the bottom of the collecting cylinder 3 is connected to the bladder 10, and an elastic element 12 is installed inside the bladder 10. When deburring the workpiece 9, the outer side of the clamping block 11 abuts against the inner wall of the workpiece 9.

[0037] Specifically, refer to Figure 4 and 5 As can be seen from the combined description, when the capsule 10 is evacuated, it can bring the clamping blocks 11 closer together, ensuring that the clamping blocks 11 are separated from the workpiece 9. When the capsule 10 is not evacuated, the elastic restoring force of each elastic element 12 (the number of elastic elements 12 is the same as the number of clamping blocks 11) causes the elastic elements 12 to drive the clamping blocks 11 away from each other, so that the clamping blocks 11 are tightly attached to the inner wall of the workpiece 9, thus completing the clamping and positioning process of the workpiece 9.

[0038] In some examples, the adjustment component 1 includes: a bracket 101, a drive motor 102, and a cylinder 103; the drive motor 102 is mounted on the bottom side of the bracket 101; the cylinder 103 is located above the bracket 101 and is connected to the output shaft of the drive motor 102; the bracket 101 provides support.

[0039] Among them, the piston rod 7 of the cylinder 103 is spirally connected to the push rod 8, the bladder 10 is fixed to the end of the push rod 8, the elastic element 12 is used to connect the center position of the bladder 10 and each arc-shaped clamp 11, one end of each elastic element 12 is connected to each other, the other end is connected to the corresponding clamp 11 and passes through the bladder 10, the bladder 10 itself is in a sealed state and contracts when air is pumped out.

[0040] The collecting cylinder 3 is connected to the support 101 by a connecting plate 16, and the bottom end of the collecting cylinder 3 is spirally equipped with a suction pump 18. The suction pump 18 is connected to the bag body 10 by a retractable air pipe 17. An electric control valve 19 is installed on the outer wall of the suction pump 18, and the electric control valve 19 is used to open and close the air inlet pipe of the air pipe 17.

[0041] The entire device can be connected to an external PLC226 controller. The controller can be used to control the entire device. The electrically controlled valve 19 is a three-way valve. It can open and close the air inlet pipe of the air pipe 17 to open and close the passage between the air pump 18 and the collection cylinder 3.

[0042] By adopting the above technical solution:

[0043] By combining the adjusting component 1 and the collecting cylinder 3, the air pump 18 at the bottom of the collecting cylinder 3 can be used to collect the waste generated during the deburring operation. At the same time, it can also drive the corresponding clamping block 11 to move, so as to clamp and release the corresponding workpiece 9, ensuring that the workpiece 9 can be processed in batches, thereby improving the overall efficiency of the deburring operation and solving the problem that traditional deburring equipment can only perform deburring operation on a single plastic product at a time.

[0044] Example 2:

[0045] Based on Example 1, this example describes the specific structure of the internal structure of the collection cylinder in a deburring device for processing plastic products, such as... Figure 7 As shown, the collecting cylinder 3 is installed on one side of the adjusting component 1, and the collecting cylinder 3 is under negative pressure, corresponding to the position of the workpiece 9 in the deburring state. The specific design position can be referred to Figure 1 This is immediately apparent.

[0046] In some examples, a filter screen 20 is installed inside the collection cylinder 3, and the filter screen 20 is always located directly above the vacuum pump 18. The cross-section of the filter screen 20 is L-shaped, and the edge of the filter screen 20 has an arc-shaped frame mesh at the same height as the vacuum pump 18. The specific shape can be referred to Figure 7 It can be seen that the purpose of designing the arc-shaped frame mesh on the filter screen 20 is that when the waste enters the collection cylinder 3 and forms a certain height, the arc-shaped frame mesh will not be completely covered, and the upper part of the mesh can ensure the smooth flow of air, thereby ensuring the smooth operation of the suction.

[0047] In addition, a door can be hinged to the side of the collection cylinder 3. After the door is opened, the waste material on the filter screen 20 can be discharged from the collection cylinder 3.

[0048] By adopting the above technical solution:

[0049] A collection cylinder 3 is designed at the deburring station. The suction force generated by the air pump 18 can be used to collect the waste. Since a filter screen 20 is set in the collection cylinder 3, the problem of the filter screen 20 being clogged due to excessive waste in the collection cylinder 3 can be avoided, which would prevent the air pumping work from being carried out smoothly. This ensures that the waste collection work can be carried out continuously and solves the problem of waste splashing and inconvenience in cleaning during the operation of traditional deburring equipment.

[0050] Example 3:

[0051] Based on Example 1, this example describes the deburring component 1 in a deburring device for processing plastic products. Figure 3 as well as Figure 6 The specific structure, such as Figure 7 As shown, the deburring component 2 is located on one side of the adjustment component 1 and acts on the surface of the workpiece 9.

[0052] In some examples, the deburring assembly 2 includes: a base frame 201, a slanted support platform 202, and a tool holder 203; the slanted support platform 202 is fixedly mounted on the top of the base frame 201; the tool holder 203 is movably mounted on the track of the slanted support platform 202, and bolts for positioning the tool holder 203 are provided on the surface of the slanted support platform 202; a blade 5 is detachably mounted on the surface of the tool holder 203, and the blade 5 is used to remove the surface of the workpiece 9, and an abrasive is inserted at the end corner of the blade 5, the abrasive contacting the inner wall edge of the workpiece 9, and the abrasive at this point can be replaced as needed.

[0053] In some examples, the grinding part includes a movable piece 6 and a cutting edge assembly disposed on the right-angle end of the movable piece 6. An insert 15 is integrally welded onto the movable piece 6. The grinding part is connected to the notch on the blade 5 by the insert 15. Bolts can also be provided on the blade 5 to position and connect the grinding part and the blade 5.

[0054] In some examples, the slice group includes a transverse slice 13 and a longitudinal slice 14, and both the transverse slice 13 and the longitudinal slice 14 are connected to the movable slice 6 by a pivot with a torsion spring.

[0055] In specific application scenarios, if workpiece 9 is relatively soft, a grinding wheel with a slicing set can be used; if workpiece 9 is relatively hard, it can be switched to... Figure 6 The rightmost grinding piece is a single piece of the tool body structure.

[0056] By adopting the above technical solution:

[0057] The deburring assembly 2 is designed with an adjustable overall position to accommodate different workpieces 9. For the abrasive part that directly contacts the workpiece 9, this abrasive part can be replaced according to the type of workpiece 9. If the workpiece 9 is relatively soft, it requires the use of... Figure 6 The abrasive with a slicing group in the middle avoids the situation where the abrasive directly damages the workpiece 9 during the deburring process due to burr clumping, reflecting the flexibility of the entire equipment.

[0058] Based on the above embodiments 1-3, it can be concluded that:

[0059] The user places several workpieces 9 in Figure 4 On the conveyor belt 4 shown, the corresponding workpiece 9 enters the workstation, and the entire equipment can be remotely controlled by a PLC226 controller.

[0060] This causes cylinder 103 to move each clamping block 11 upwards. At this time, the electronically controlled valve 19 opens the passage connecting the suction pump 18 and the bladder 10, causing the bladder 10 to contract. Figure 5 Each elastic element 12 is in a state of elastic compression until the clamping block 11 enters the groove on the bottom side of the workpiece 9 from below. At this time, the capsule 10 no longer contracts, and the elastic restoring force of the elastic element 12 drives each clamping block 11 to complete the clamping and positioning of the workpiece 9.

[0061] Then, the electrically controlled valve 19 opens the passage connecting the air pump 18 and the collection cylinder 3, and at the same time, the drive motor 102 drives the entire workpiece 9 to rotate. At this time, the blade 5 in the deburring assembly 2 has already been adjusted to... Figure 1 At the position shown, the grinding wheel is used to deburr the workpiece 9. At the same time, the collection cylinder 3 collects the waste material.

[0062] After the deburring operation is completed, the drive motor 102 stops rotating, and the cylinder 103 drives the processed workpiece 9 back to its initial state. After it stops on the surface of the conveyor belt 4, the passage connecting the vacuum pump 18 and the bladder 10 is opened again by the electric control valve 19, so that the clamping block 11 is separated from the workpiece 9.

[0063] Finally, the transmission belt 4 moves forward to complete the deburring process of the second workpiece 9, and so on, thereby achieving batch processing.

[0064] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
