Description

Technical Field

[0001] This utility model relates to the technical field of plastic parts production and processing, specifically to a deburring device for plastic parts production. Background Technology

[0002] Plastics are materials made of high molecular polymers, characterized by their lightweight, durability, and high plasticity. They are widely used in daily life and industrial fields, such as packaging, containers, electronic products, and building materials. With the development of the manufacturing industry, the types and shapes of plastic parts have become increasingly diverse. In the production process, especially for cylindrical plastic parts, mold casting is generally used for mass production. During the mold production of such cylindrical plastic parts, some unhardened plastic material is detached from the edges and openings of the workpiece when the mold is removed, resulting in burrs. To improve the production quality of plastic parts, it is necessary to remove these burrs after processing.

[0003] However, in the existing deburring process of plastic parts production, workers use grinding equipment to grind individual plastic parts to remove burrs. This method of deburring is inefficient, and manual grinding of individual plastic parts increases the workload of workers. If large-scale equipment is used for assembly line grinding, since the existing grinding equipment does not have a positioning function, workers still need to manually position each cylindrical plastic part. In response to this, this design proposes a deburring device for plastic parts production. Utility Model Content

[0004] The purpose of this invention is to provide a deburring device for the production of plastic parts, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a deburring device for the production of plastic parts, including a support base, a conveyor belt, and a positioning mechanism and a grinding mechanism, both installed on the top of the support base, wherein the conveyor belt is installed on the top of the support base.

[0006] The positioning mechanism includes guide frames installed on the support base on both sides of the conveyor belt. Multiple guide rollers are rotatably connected at equal distances to the inner walls of one end of each of the two guide frames. Connecting grooves are provided at both ends of the inner wall of the support base. A bidirectional lead screw is rotatably connected to the inner wall of the support base. A support pad is installed on one side of the top of the support base. A first motor is installed on the top of the support pad. Pulleys are fixedly provided at the output end of the first motor and at the middle position of the outer wall of the bidirectional lead screw. A belt strip is sleeved between the outer walls of the two pulleys, and the outer wall of the belt strip is inserted and connected to the bottom of the support base. Connecting frames are inserted and connected to the inner walls of the two connecting grooves. A clamping plate is fixedly provided at one end of the top of each of the two connecting frames.

[0007] In one example, each of the two connecting frames has a screw hole at one end at the bottom, and the outer walls of both ends of the bidirectional lead screw pass through the inner walls of the two connecting grooves and are threaded to the inner walls of the two screw holes. A protective pad is fixed on one side of each of the two clamping plates.

[0008] In one example, the grinding mechanism includes a support column fixedly installed on one side edge of the top of the support base. A limiting groove is formed on the inner wall of the support column, and an electric push rod is installed at the bottom of the inner wall of the limiting groove. A support frame is sleeved on the outer wall of the support column.

[0009] In one example, a limiting frame is fixedly provided on the inner wall of one end of the support frame, the outer wall of the limiting frame is inserted and connected to the inner wall of the limiting slide, and the output end of the electric push rod is fixedly connected to the bottom of the limiting frame. A support bar is fixedly provided on one side of the bottom of the support frame, and an infrared sensor is installed on one side of the support bar.

[0010] In one example, a grinding disc is rotatably connected to one side of the bottom of the support frame, a second motor is installed on one side of the top of the support frame, and one end of the grinding disc passes through the top of the support frame and is fixedly connected to the output end of the second motor.

[0011] In one example, the conveyor belt, the first motor, the electric push rod, and the second motor are all electrically connected to an external power source via infrared sensors.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a positioning mechanism, when removing burrs, the cylindrical plastic is placed vertically on the conveyor belt for conveying. With the help of the guide frame and guide roller, it is limited and centered during the transfer. When it is transferred to the bottom of the grinding mechanism, the first motor is triggered and started, which drives the bidirectional lead screw to rotate, causing the connecting frame to slide in the connecting groove. This causes the clamping plates at the top to come closer together, thereby clamping and positioning the plastic part. This facilitates the normal and accurate execution of subsequent grinding operations, eliminating the need for manual positioning and grinding by the staff, improving the efficiency of burr removal, and reducing the workload of the staff.

[0020] 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.

[0021] Please see Figure 1-6 This utility model provides a technical solution: a deburring device for the production of plastic parts, including a support base 1, a conveyor belt 2, and a positioning mechanism 3 and a grinding mechanism 4, both installed on the top of the support base 1. The conveyor belt 2 is installed on the top of the support base 1.

[0022] The positioning mechanism 3 includes guide frames 301 installed on both sides of the support base 1 and the conveyor belt 2. Multiple guide rollers 302 are rotatably connected at equal distances to the inner walls of one end of the two guide frames 301. Connecting grooves 303 are opened at both ends of the inner wall of the support base 1. A bidirectional lead screw 304 is rotatably connected to the inner wall of the support base 1. A support pad 305 is installed on one side of the top of the support base 1. A first motor 306 is installed on the top of the support pad 305. A pulley 307 is fixedly provided at the output end of the first motor 306 and at the middle position of the outer wall of the bidirectional lead screw 304. A belt strip 308 is sleeved between the outer walls of the two pulleys 307, and the outer wall of the belt strip 308 is inserted and connected to the bottom of the support base 1. Connecting frames 309 are inserted and connected to the inner walls of the two connecting grooves 303. A clamping plate 310 is fixedly provided at one end of the top of the two connecting frames 309.

[0023] In use, the produced cylindrical plastic parts are transported in batches via conveyor belt 2. During transport, the workers manually place the cylindrical plastic parts vertically on conveyor belt 2. When the plastic parts pass through guide frame 301, as per the instruction manual... Figure 2 As shown, one end of the conveyor belt is inclined, so that when the conveyor belt 2 transports the plastic part, the plastic part is continuously guided by the guide frame 301 and continuously limited to the middle position of the conveyor belt 2 for transport. It is then transported to the middle position between multiple guide rollers 302 at one end of the two guide frames 301, so that the guide rollers 302 contact the outer wall of the plastic part and rotate to assist the plastic part in centering and transporting. When it is transported to the bottom of the polishing mechanism 4, the blocking infrared sensor 407 is triggered to trigger the switch, so that the conveyor belt 2 stops transporting and the first motor 306 starts, so that it carries the plastic part through the linkage of the pulley 307 and the belt strip 308. The bidirectional lead screw 304 rotates, and at the same time, it is threadedly connected to the screw holes 311 on the upper end of the two connecting brackets 309. The two connecting brackets 309 are inserted and connected in the two connecting grooves 303, so that the clamping plates 310 above the two connecting brackets 309 come closer to each other and press against both sides of the outer wall of the plastic part to fix it. Then, in conjunction with the start of the grinding mechanism 4, it descends and contacts the top opening end of the plastic part for grinding. There is no need for the staff to manually position and fix it, nor is there a need for the staff to manually grind it, which improves the efficiency of deburring and reduces the workload of the staff.

[0024] Each of the two connecting brackets 309 has a screw hole 311 at one end of its bottom. The outer walls of both ends of the bidirectional lead screw 304 pass through the inner walls of the two connecting grooves 303 and are threaded to the inner walls of the two screw holes 311. A protective pad 312 is fixedly provided on one side of each of the two clamping plates 310. The protective pad 312 contacts the outer wall of the plastic part through the protective pad 312 to prevent wear of the plastic part during the squeezing and clamping process.

[0025] Furthermore, the grinding mechanism 4 includes a support column 401 fixedly installed on one side edge of the top of the support base 1. A limiting groove 402 is formed on the inner wall of the support column 401. An electric push rod 403 is installed at the bottom of the inner wall of the limiting groove 402. A support frame 404 is sleeved on the outer wall of the support column 401. The limiting groove 402 formed at the upper end of the support column 401 is as shown in the attached instruction manual. Figure 5 As shown, grooves are opened on both sides of the outer wall of the support column 401, and the grooves on both sides are connected to the limiting slide groove 402 therein. The support frame 404 slides on the upper limit of the support column 401 through the grooves on both sides.

[0026] Furthermore, a limiting frame 405 is fixedly provided on the inner wall of one end of the support frame 404. The outer wall of the limiting frame 405 is inserted and connected to the inner wall of the limiting slide groove 402. The output end of the electric push rod 403 is fixedly connected to the bottom of the limiting frame 405. A support bar 406 is fixedly provided on one side of the bottom of the support frame 404. An infrared sensor 407 is installed on one side of the support bar 406. When the support frame 404 slides on the support column 401, it slides inside the limiting slide groove 402 through the limiting frame 405 and is pushed by the electric push rod 403 to achieve lifting and lowering.

[0027] Furthermore, a grinding disc 408 is rotatably connected to one side of the bottom of the support frame 404, and a second motor 409 is installed on one side of the top of the support frame 404. One end of the grinding disc 408 passes through the top of the support frame 404 and is fixedly connected to the output end of the second motor 409. When the cylindrical plastic part is conveyed to the guide frame 301 area by the conveyor belt 2 and then center-limited, when it reaches the position directly opposite the support column 401, the cylindrical plastic part will block the infrared sensor 407, thereby triggering the control switch on the control panel, causing the conveyor belt 2 to be controlled to stop conveying, preventing the plastic part from... Then it is passed on, and then the first motor 306, electric push rod 403 and second motor 409 are started. After the first motor 306 is started, the positioning mechanism 3 operates to position and clamp it. Then the electric push rod 403 starts to push the limit frame 405 and then the support frame 404 slides and rises on the support column 401, so that the grinding disc 408 at the bottom of the plastic part contacts the burr at the opening end. The second motor 409 starts to rotate the grinding disc 408 to grind the burr, thereby achieving the purpose of automated burr removal, improving the efficiency of burr removal, and improving the convenience of burr grinding.
