Description

Technical Field

[0001] This utility model relates to the field of injection molding processing technology, and in particular to a deburring mechanism on a washing machine accessory conveyor line. Background Technology

[0002] Washing machines require the assembly of many injection-molded parts during production. Because the injection molding process often results in burrs on the edges of these parts, these burrs need to be trimmed before use. Currently, the trimming of burrs on small, round injection-molded machine parts used in washing machines is mostly done manually, which is inefficient.

[0003] Chinese Patent No. CN222858565U discloses a burr removal mechanism for injection-molded parts in washing machines, including a worktable; a guide post is fixedly connected to the top edge of the outer wall of the worktable, and the guide post is L-shaped; a motor is fixedly connected to one side of the outer wall of the guide post through a fixing block; a sliding plate is slidably connected to the top of the inner wall of the guide post; the outer wall of the positioning plate is flush with the tip of the cutting blade, so that when the injection-molded part is placed, the part of the injection-molded part that crosses the positioning plate is the burr removal part, allowing the operator to clearly observe the part of the injection-molded part to be removed. This allows the operator to adjust the position of the injection-molded part before cutting, ensuring that the device removes neither too much nor too little burr from the injection-molded part. This not only avoids wasting materials but also eliminates the need for secondary processing, thereby improving work efficiency and reducing the workload of the operator.

[0004] However, when using this patent, the use of a spring reduces its positioning effect, and because a positioning plate is used and the cutting blade is located on one side, it is impossible to remove burrs from the surface of the circular injection molded part. Utility Model Content

[0005] Based on the aforementioned technical problems, this utility model proposes a deburring mechanism for a washing machine accessory conveyor line.

[0006] This utility model proposes a deburring mechanism on a washing machine accessory conveyor line, including a conveyor for transporting injection molded accessories. A limit switch is fixedly installed on the inner surface of the side plate of the conveyor. A bracket is fixedly installed on the upper surface of the side plate of the conveyor. A support disc is provided inside the bracket. Clamping blocks are symmetrically distributed on the lower surface of the support disc. Grooves are opened on the opposite side surfaces of the two clamping blocks. A grinding block is slidably connected to the inner wall of the groove. At the same time, an arc-shaped cutting blade is provided on the lower surface of the clamping block.

[0007] Preferably, a telescopic cylinder is fixedly installed on the upper surface of the bracket, and a limiting plate is fixedly connected to one end of the piston rod of the telescopic cylinder. Limiting grooves are symmetrically distributed on the inner surface of the bracket, and the surface of the limiting plate is slidably engaged with the inner wall of the limiting groove.

[0008] Through the above technical solution, the extension and retraction of the piston rod of the telescopic cylinder drives the limiting plate connected to it to move up and down along the inner wall of the limiting groove.

[0009] Preferably, a heat dissipation shell is fixedly installed on the lower surface of the limiting plate, a drive motor is fixedly installed on the inner wall of the heat dissipation shell, one end of the output shaft of the drive motor passes through the support disc and is fixedly sleeved with a connecting plate, and the grinding block is disposed on the lower surface of the connecting plate.

[0010] Through the above technical solution, the rotation of the output shaft of the drive motor drives the connecting plate connected to it to rotate, thereby driving the grinding block to rotate.

[0011] Preferably, electric motors are symmetrically distributed and fixedly installed on the outer surface of the support disc, and sliding grooves are symmetrically distributed on the lower surface of the support disc. Screws are installed on the inner walls of the two sliding grooves through bearings, and one end of the output shaft of each of the two electric motors is fixedly connected to one end of the two screws through couplings.

[0012] Through the above technical solution, the rotation of the output shafts of the two electric motors drives the screws connected to them to rotate.

[0013] Preferably, the surfaces of the two screws are threaded with movable blocks, the surfaces of the movable blocks are slidably engaged with the inner wall of the groove, and the upper surface of the clamping block is fixedly connected to the lower surface of the movable blocks.

[0014] Through the above technical solution, the rotation of the two screws respectively drives the two moving blocks to move relative to each other along the inner wall of the slide groove. The movement of the moving blocks drives the clamping block to move, thereby making it easier for the clamping block to hold the injection molded auxiliary parts.

[0015] Preferably, the grinding block is a flexible abrasive block, the connecting plate is made of aluminum alloy, and an electromagnet is embedded on the upper surface of the grinding block.

[0016] Through the above technical solution, the flexible abrasive block adopts a polyurethane substrate abrasive, which can adapt to the burr thickness of 0.1-2mm. The abrasive block is attracted to the connecting plate by an electromagnet, so that the rotation of the connecting plate can drive the abrasive block to rotate, thereby deburring the surface of the injection molded auxiliary parts.

[0017] Preferably, electric push rods are symmetrically distributed on the outer surface of the side plate of the conveyor, and one end of the piston of each of the two electric push rods passes through the side plate of the conveyor and is fixedly connected to an arc-shaped push plate.

[0018] The above technical solution enables the extension and retraction of the electric push rod piston to move the arc-shaped push plate connected to it, thereby causing the two arc-shaped push plates to move relative to each other. This facilitates the position adjustment of the injection molding accessories on the conveyor, and further facilitates the deburring of the surface of the injection molding accessories.

[0019] The beneficial effects of this utility model are as follows:

[0020] By setting up a support disc, it is easy to install the drive motor and electric motor. A connecting plate is set on the lower surface of the support disc. The rotation of the output shaft of the drive motor drives the connecting plate connected to it to rotate. An electromagnet is used to connect the grinding block to the connecting plate, which facilitates the rotation of the grinding block. The grinding block removes the burrs on the surface of the injection molded part. At the same time, the rotation of the output shaft of the electric motor drives the screw to rotate, which causes the clamping block to move relative to the inner wall of the slide, thereby driving the cutting blade to remove the burrs on the surface of the injection molded part in contact with it, thus achieving the effect of removing the burrs on the surface of the injection molded part.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figures 1-6 A deburring mechanism on a washing machine accessory conveyor line includes a conveyor 1 for transporting injection molded accessories. A limit switch 2 is fixedly installed on the inner surface of the side plate of the conveyor 1. A bracket 3 is fixedly installed on the upper surface of the side plate of the conveyor 1. A support disc 4 is provided inside the bracket 3. Clamping blocks 5 are symmetrically distributed on the lower surface of the support disc 4. Grooves 6 are opened on the opposite side surface of the two clamping blocks 5. A grinding block 7 is slidably connected to the inner wall of the groove 6. At the same time, a cutting blade 8 is provided on the lower surface of the clamping block 5.

[0030] In order to position the injection molded parts transported on the conveyor 1, electric push rods 20 are symmetrically distributed on the outer surface of the side plate of the conveyor 1. The piston end of each of the two electric push rods 20 passes through the side plate of the conveyor 1 and is fixedly connected to an arc-shaped push plate 21. The extension and retraction of the piston of the electric push rod 20 drives the arc-shaped push plate 21 connected to it to move, thereby driving the two arc-shaped push plates 21 to move relative to each other. This facilitates the position adjustment of the injection molded parts on the conveyor 1, and further facilitates the deburring of the surface of the injection molded parts.

[0031] In order to move the grinding block 7 and the cutting blade 8 closer to the injection molding auxiliary parts, a telescopic cylinder 9 is fixedly installed on the upper surface of the bracket 3. One end of the piston rod of the telescopic cylinder 9 is fixedly connected to a limiting plate 10. Limiting grooves 11 are symmetrically distributed on the inner surface of the bracket 3. The surface of the limiting plate 10 is slidably engaged with the inner wall of the limiting groove 11. The extension and retraction of the piston rod of the telescopic cylinder 9 drives the limiting plate 10 connected to it to move up and down along the inner wall of the limiting groove 11, thereby facilitating the movement of the grinding block 7 and the cutting blade 8 closer to or away from the injection molding auxiliary parts on the conveyor 1.

[0032] In order to drive the grinding block 7 to rotate and thus remove the burrs on the surface of the circular injection molded auxiliary part, a heat sink 12 is fixedly installed on the lower surface of the limiting plate 10. A drive motor 13 is fixedly installed on the inner wall of the heat sink 12. One end of the output shaft of the drive motor 13 passes through the support disc 4 and is fixedly sleeved with a connecting plate 14. The grinding block 7 is set on the lower surface of the connecting plate 14. The rotation of the output shaft of the drive motor 13 drives the connecting plate 14 connected to it to rotate, thereby driving the grinding block 7 to rotate.

[0033] To facilitate the grinding block 7 to adapt to and grind the surface of the circular injection molded part, the grinding block 7 is a flexible abrasive block. The connecting plate 14 is made of aluminum alloy. An electromagnet 19 is embedded on the upper surface of the grinding block 7. The flexible abrasive block, through the composite structure of elastic substrate and abrasive particles, can adapt to workpieces with curved surfaces or complex shapes, thereby enabling uniform grinding of the surface of the circular injection molded part. At the same time, the grinding block 7 can be attracted to the aluminum alloy connecting plate 14 through the electromagnet 19, which facilitates the rotation of the connecting plate 14 to drive the grinding block 7 to rotate, thereby deburring the surface of the injection molded part.

[0034] To enable the cutting blade 8 to remove burrs from the surface of the injection-molded part, electric motors 15 are symmetrically fixedly installed on the outer surface of the support disc 4. Slide grooves 16 are symmetrically distributed on the lower surface of the support disc 4. Screws 17 are mounted on the inner walls of both slide grooves 16 via bearings. One end of the output shaft of each of the two electric motors 15 is fixedly connected to one end of each of the two screws 17 via couplings. Moving blocks 18 are threaded onto the surfaces of the two screws 17, and the surfaces of the moving blocks 18 slide and engage with the inner walls of the slide grooves 16. The clamping block 5... The upper surface is fixedly connected to the lower surface of the movable block 18. The rotation of the output shafts of the two electric motors 15 drives the screws 17 connected to them to rotate. The rotation of the two screws 17 drives the two movable blocks 18 to move relative to each other along the inner wall of the slide groove 16. The movement of the movable blocks 18 drives the clamping block 5 to move, so that the clamping block 5 can approach the injection molding auxiliary part. At the same time, under the action of the piston rod of the telescopic cylinder 9, the cutting blade 8 is driven to remove the burrs on the surface of the injection molding auxiliary part, and the clamping block 5 can hold the injection molding auxiliary part, which makes it easier for the grinding block 7 to rotate.

[0035] By setting up a support disc 4, it is easy to install the drive motor 13 and the electric motor 15. A connecting plate 14 is set on the lower surface of the support disc 4. The rotation of the output shaft of the drive motor 13 drives the connecting plate 14 connected to it to rotate. The electromagnet 19 is used to connect the grinding block 7 to the connecting plate 14, which facilitates the rotation of the grinding block 7. The grinding block 7 removes the burrs on the surface of the injection molded auxiliary part. At the same time, the rotation of the output shaft of the electric motor 15 drives the screw 17 to rotate, which causes the clamping block 5 to move relative to the inner wall of the slide groove 16, thereby driving the cutting blade 8 to remove the burrs on the surface of the injection molded auxiliary part in contact with it, thus achieving the effect of removing the burrs on the surface of the injection molded auxiliary part.

[0036] Working principle: During use, the produced round injection molded parts are transported through conveyor 1. When limit switch 2 senses the injection molded parts, it controls conveyor 1 to stop running. Then, electric push rods 20 are started. The extension of the pistons of the two electric push rods 20 respectively drives the arc-shaped push plates 21 connected to them to move closer to each other, thereby adjusting the position of the injection molded parts until both arc-shaped push plates 21 are in contact with the injection molded parts. Then, the pistons of the electric push rods 20 are reset.

[0037] Then, the telescopic cylinder 9 is activated. The extension of the piston rod of the telescopic cylinder 9 causes the limiting plate 10 connected to it to move down along the inner wall of the limiting groove 11. The downward movement of the limiting plate 10 causes the heat dissipation housing 12 connected to it, the drive motor 13 inside the heat dissipation housing 12, the support disc 4 and the connecting plate 14 to move down, thereby causing the grinding block 7, the clamping block 5 and the cutting blade 8 on the clamping block 5 connected to the connecting plate 14 via the electromagnet 19 to move down. At the same time, the electric motor 15 is activated according to the position of the injection molding auxiliary part. The rotation of the output shafts of the two electric motors 15 causes the screw 17 connected to them to rotate. The rotation of the two screws 17 respectively causes the two moving blocks 18 to move relative to each other along the inner wall of the slide groove 16. The movement of the moving blocks 18 causes the clamping block 5 to move, thereby making it easier for the clamping block 5 to approach the injection molding auxiliary part, so that it can move down along the surface of the injection molding auxiliary part, and thus make it easier for the cutting blade 8 to remove the burrs from the surface of the injection molding auxiliary part.

[0038] When the cutting blade 8 and clamping block 5 come into contact with the conveyor belt of the conveyor 1, the drive motor 13 is started. The rotation of the output shaft of the drive motor 13 drives the connecting plate 14 connected to it to rotate, which in turn facilitates the rotation of the grinding block 7, so that the grinding block 7 removes the burrs on the surface of the injection molded auxiliary parts.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
