Description

Technical Field

[0001] This utility model relates to the field of plastic bucket processing equipment, and in particular to a device for sanding burrs on the surface of plastic buckets. Background Technology

[0002] During the manufacturing process of plastic buckets, burrs, flash, and other defects often remain on the surface of the molded buckets. These defects not only affect the appearance of the plastic buckets but can also cause harm to users or affect the product's sealing performance during subsequent use. Therefore, plastic bucket surface burr removal equipment has become an indispensable and important piece of equipment on the plastic bucket production line, and its performance directly affects the quality of the finished plastic buckets and production efficiency.

[0003] Existing plastic bucket surface deburring devices typically use a fixed roller frame to support the buckets to be deburred. The grinding head is driven by a motor to rotate at high speed, and the burrs are removed through contact friction between the grinding head and the surface of the plastic bucket. The overall structure of the equipment is relatively fixed, and the movement trajectory and working height of the grinding head are mostly preset. Operators can only adjust a few parameters, such as the rotation speed of the grinding head, to achieve deburring treatment on the surfaces of different plastic buckets.

[0004] However, due to the diverse specifications and sizes of plastic buckets, existing grinding devices, with their relatively fixed roller frame height, are difficult to flexibly match plastic buckets of different sizes. When grinding plastic buckets with significant size differences is required, operators often need to spend a lot of time disassembling and replacing the roller frame, which not only reduces production efficiency but also easily leads to damage to equipment parts and increases maintenance costs, failing to meet the actual needs of diversified production. Therefore, a plastic bucket surface deburring device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a plastic bucket surface burr grinding device, which aims to improve the problem that the traditional roller frame has a relatively fixed height and is difficult to match plastic buckets of different sizes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for sanding burrs on the surface of a plastic bucket includes a sander, a support platform slidably connected inside the sander, multiple roller frames fixedly connected to the top of the support platform, and a lifting assembly on the outer wall of the support platform.

[0008] The lifting assembly includes multiple sliders, the tops of which are fixedly connected to the bottom of the support platform. A fixed base is fixedly connected to the bottom of the inner wall of the grinder. A motor is fixedly connected inside the fixed base. A worm gear is fixedly connected to the output end of the motor. Multiple support plates are fixedly connected to the top of the fixed base. A rotating shaft is rotatably connected inside each support plate. A worm wheel is fixedly connected to the outer wall of each rotating shaft. The multiple worm wheels mesh with the worm gear. Transmission plates are fixedly connected to both ends of the rotating shaft. A sliding groove is opened inside each transmission plate. A transmission assembly is provided on the outer wall of each transmission plate.

[0009] As a further description of the above technical solution:

[0010] Each of the transmission components includes multiple connecting plates located on both sides of the transmission plate, and a rotating bar is fixedly connected between two adjacent connecting plates.

[0011] As a further description of the above technical solution:

[0012] Each of the rotating bars has a slider 2 rotatably connected to its outer wall, and each slider 2 is slidably connected to the inner wall of the groove.

[0013] As a further description of the above technical solution:

[0014] The tops of the multiple connecting plates are fixedly connected to the bottom of the slider one, and a support seat is slidably connected to the outer wall of each slider one. One side of each transmission plate extends through to the outside of the support seat.

[0015] As a further description of the above technical solution:

[0016] The bottom of the multiple support bases is fixedly connected to the top of the fixed base, and a collection component is provided on one side of the grinder.

[0017] As a further description of the above technical solution:

[0018] The collection assembly includes a collection box, the outer wall of which is fixedly connected to one side of the grinding machine, and a collection trough is provided inside the collection box.

[0019] As a further description of the above technical solution:

[0020] A baffle is fixedly connected to one side of the collection box, and multiple T-shaped sliders are fixedly connected to one side of the baffle.

[0021] As a further description of the above technical solution:

[0022] Multiple T-shaped sliders are slidably connected to baffles 2 on their outer walls. Multiple fixing bolts are threaded inside the baffles 1, and one end of each fixing bolt extends through to one side of the baffles 2.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the worm gear is driven by a motor to rotate, causing the transmission plate to rotate around the pivot, thereby driving the support platform at the top of the slider to slide up and down on the inner wall of the grinder. The self-locking property between the worm gear and the worm wheel is used to fix the position of the roller frame at the top of the support platform, achieving the effect of roller frame height adjustment. This solves the problem that the traditional roller frame height is relatively fixed and difficult to match plastic buckets of different sizes, thus enhancing the practicality of the equipment.

[0025] 2. In this utility model, the total length of the inclined baffle one and baffle two is adjusted by sliding baffle two on the outer wall of the T-shaped slider. Then, the position of baffle two is fixed by fixing bolts. Baffle one and baffle two are used to block the debris that splashes to one side and guide it into the inner wall of the collection tank, thereby achieving the effect of debris collection. This solves the problem that a large amount of debris is generated during the grinding of plastic barrels, which increases the difficulty of subsequent cleaning and improves the collection efficiency of plastic debris.

[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] Reference Figures 1-4 This utility model provides an embodiment of a plastic bucket surface burr removal and polishing device, including a grinder 1. The grinder 1 utilizes the kinetic energy generated by the grinding wheel to perform grinding, polishing, and other operations on the workpiece surface. During the grinding process, different grinding effects are achieved by adjusting the rotation speed of the grinder 1 and controlling the pressure applied to the workpiece. Simultaneously, the moving direction and trajectory of the grinder 1 are adjusted in a timely manner according to the condition of the workpiece surface, thereby achieving the processing objectives of smoothing, deburring, and polishing the workpiece surface. This is prior art and will not be described in detail here. A support platform 2 is slidably connected inside the grinder 1, and multiple roller frames 3 are fixedly connected to the top of the support platform 2. A lifting assembly is located on the outer wall of the support platform 2.

[0036] The lifting assembly includes multiple sliders 12, the tops of which are fixedly connected to the bottom of the support platform 2. The sliders 12 slide in conjunction with the support base 11, achieving stable lifting of the support platform 2. A fixed base 4 is fixedly connected to the bottom of the inner wall of the grinder 1. The fixed base 4 supports the motor 5 and the worm gear 6, ensuring the stability of the transmission structure. The motor 5 is fixedly connected inside the fixed base 4, and the worm gear 6 is fixedly connected to the output end of the motor 5. The worm gear 6 meshes with the worm wheel 7 for transmission, achieving power transmission and self-locking functions. Multiple support plates 9 are fixedly connected to the top of the fixed base 4. Support plate 9 supports the rotating shaft 8, ensuring the rotational stability of the transmission plate 10. Each support plate 9 has a rotating shaft 8 internally connected. The rotating shaft 8, in conjunction with the transmission plate 10, performs circular motion, driving the connecting plate 16 to achieve linear motion conversion. Each rotating shaft 8 has a worm gear 7 fixedly connected to its outer wall. The worm gear 7, in conjunction with the worm 6, performs speed reduction transmission, improving torque output accuracy. Multiple worm gears 7 mesh with the worm 6. Transmission plates 10 are fixedly connected to both ends of the rotating shaft 8. The transmission plates 10 drive the slider 14 to move via grooves 13, achieving motion conversion. Each transmission plate 10 has a groove 13 internally. The slide groove 13 cooperates with the second slider 14 for sliding guidance, limiting the movement trajectory of the connecting plate 16. Each transmission plate 10 has a transmission assembly on its outer wall. The transmission assembly converts rotational motion into linear motion, driving the lifting and lowering of the support platform 2. Each transmission assembly includes multiple connecting plates 16. The connecting plates 16 connect the first slider 12 and the rotating bar 15, transmitting lifting power. The connecting plates 16 are located on both sides of the transmission plate 10. A rotating bar 15 is fixedly connected between adjacent connecting plates 16. The rotating bar 15 cooperates with the second slider 14 for rotational motion, reducing frictional resistance. The outer wall of each rotating bar 15 is equipped with a transmission assembly. The moving connection includes a second slider 14, which slides in conjunction with the slide groove 13 to achieve a conversion from circular to linear motion. Each second slider 14 is slidably connected to the inner wall of the slide groove 13. The tops of multiple connecting plates 16 are fixedly connected to the bottom of the first slider 12. Each first slider 12 has a support seat 11 slidably connected to its outer wall. The support seat 11 is used to limit the movement trajectory of the first slider 12 and ensure the stability of the lifting process. One side of each transmission plate 10 extends through to the outside of the support seat 11. The bottoms of multiple support seats 11 are fixedly connected to the top of the fixed seat 4. A collection component is provided on one side of the grinder 1.

[0037] Reference Figure 1 , Figure 5 and Figure 6The collection component includes a collection box 17, which is used to centrally store grinding debris for easy subsequent cleaning. The outer wall of the collection box 17 is fixedly connected to one side of the grinder 1. The collection box 17 has a collection groove 18 inside, which is used to contain splashed debris and prevent pollution of the working environment. A baffle 19 is fixedly connected to one side of the collection box 17. The baffle 19 works with a baffle 20 to adjust its length to accommodate different splash ranges. Multiple T-shaped sliders 22 are fixedly connected to one side of the baffle 19. The T-shaped sliders 22 work with the baffle 20 to guide the sliding motion and ensure the stability of the adjustment process. The outer wall of the multiple T-shaped sliders 22 is slidably connected to the baffle 20. The baffle 20 is used to expand the shielding range and enhance the debris collection effect. Multiple fixing bolts 21 are threaded inside the baffle 19. The fixing bolts 21 are used to lock the position of the baffle 20 and keep the structure fixed after adjustment. One end of the multiple fixing bolts 21 extends through to one side of the baffle 20.

[0038] Working principle: During the height adjustment of the roller frame 3, the drive motor 5 drives the worm gear 6 to rotate. Since the worm gear 6 meshes with multiple worm wheels 7, the rotation of the worm gear 6 transmits power, driving the worm wheels 7 and the fixed rotating shaft 8 to rotate within the support plate 9. This causes the transmission plates 10 at both ends of the rotating shaft 8 to rotate with the rotating shaft 8, making circular motion with the rotating shaft 8 as the center. During this process, the sliding groove 13 on the inner wall of the transmission plate 10 will drive the connecting plate 16 to move through the slider 14 and the rotating bar 15, converting the circular motion of the transmission plate 10 into the linear motion of the connecting plate 16. This causes the slider 12 to slide within the support base 11, driving the bearing platform 2 and the top roller frame 3 to move up and down along the inner wall of the grinder 1, thus completing the height adjustment. The self-locking property between the worm gear 6 and the worm wheel 7 can fix the position of the roller frame 3, adapting to different sizes of plastic buckets.

[0039] During the collection of plastic debris, baffle 20 is pushed to slide on the outer wall of T-shaped slider 22. The total length of baffle 19 and baffle 20 is adjusted. Then, baffle 20 is threaded through baffle 19 with fixing bolt 21 to fix the position of baffle 20. When grinding plastic buckets, debris will be generated and splashed. Baffle 19 and baffle 20 are used to block the debris that splashes to one side. The inclined structure of baffle 19 and baffle 20 guides it into the collection groove 18 of collection box 17, realizing debris collection, reducing the difficulty of subsequent cleaning, and improving collection efficiency.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
