Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically a tool for removing burrs from plastic products. Background Technology

[0002] With the rapid development of the plastics industry and the continuous improvement of plastic performance, plastic parts have been used more widely. Plastic parts are replacing traditional metal parts in different fields. A well-designed plastic part can often replace multiple traditional metal parts, thereby simplifying product structure and saving manufacturing costs.

[0003] Plastics are usually extruded using molding dies, but the extrusion process can easily leave burrs on the finished product, making it difficult to use directly. Therefore, the burrs need to be removed before the product can be used.

[0004] For example, patent document CN220534716U discloses a system including a workbench, a fixing mechanism, and a processing mechanism. A conveyor belt is installed on the workbench. The fixing mechanism includes a support plate with a fixing frame inside. The fixing frame contains a baffle and a pair of fixing plates, with multiple clamping blocks between the baffle and the pair of fixing plates. The processing mechanism includes a work frame with a support shaft inserted inside. A brush is mounted on the support shaft. A support frame and an ice sprayer are installed on the workbench. The ice sprayer is connected to an ice conveying pipe, and multiple dry ice spray guns are installed on the ice conveying pipe. By configuring the relevant mechanisms of the deburring equipment for medical plastic manufacturing, the deburring equipment can fix the medical plastic during deburring, making it less prone to movement. This reduces the workload of workers, speeds up production, increases economic benefits, and minimizes the risk of injury to workers.

[0005] In the aforementioned prior art, products are conveyed directly through the cooperation of the conveyor belt and the protrusions on the support plate. However, the lack of fixation between the support plate and the conveyor belt results in poor stability. Therefore, a new tool for removing burrs from plastic products is proposed to optimize the aforementioned prior art. Utility Model Content

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.

[0025] Please see Figures 1-4In this embodiment of the present invention, a tool for removing burrs from plastic products includes a base plate 1. A first mounting cover 2 and a second mounting cover 3 are fixedly connected to the base plate 1 in sequence. The bottoms of both the first mounting cover 2 and the second mounting cover 3 are open. Both the first mounting cover 2 and the second mounting cover 3 have mounting cavities. A brush 4 is rotatably mounted in the mounting cavity of the first mounting cover 2. The brush 4 is fixedly mounted at the output end of a corresponding first motor 5. The first motor 5 can drive the brush 4 to rotate. The brush 4 can remove larger burrs from the plastic product by rotating. The first motor 5 is fixedly mounted on the side wall of the first mounting cover 2. An ice conveying pipe 6 is fixedly mounted in the mounting cavity of the second mounting cover 3. One end of the ice conveying pipe 6 passes through the mounting cavity and is connected to an ice sprayer 7. The ice sprayer 7 is fixedly mounted on the side wall of the second mounting cover 3. A dry ice spray gun 8 is fixedly connected at equal intervals to a section of the ice conveying pipe 6 located in the mounting cavity. The ice sprayer 7 can store dry ice and can spray dry ice at high speed from the inside of the dry ice spray gun 8 through the ice conveying pipe 6 to remove burrs from the plastic product. Two sets of slide rails 9 are fixedly connected parallel to each other on the top surface of the base plate 1, corresponding to the lower part of the first mounting cover 2 and the second mounting cover 3. A conveying groove 10 is provided above the slide rails 9. A slider 11 is symmetrically fixedly connected to the bottom surface of each conveying groove 10. The slider 11 is slidably connected to the corresponding slide rail 9. A matching fixing component 12 is placed inside the conveying groove 10. The fixing component 12 includes a support plate 13. Fixing slots 14 are symmetrically opened on both sides of the support plate 13. A fixing plug 15 is fixedly connected to the inner wall of the conveying groove 10 at one of the fixing slots 14. An insertable plug 16 is inserted and fixedly connected to the clamping plate 17. The clamping plate 17 and the inner wall of the conveying groove 10 together clamp the support plate 13. The clamping plate 17 is located in the conveying groove 10 and slides against the inner wall of the conveying groove 10. The conveying groove 10 is threadedly connected to the clamping plate 17 with a first threaded handle 18. The first threaded handle 18 is inserted into the conveying groove 10 and rotated with the clamping plate 17. The conveying groove 10 is provided with a threaded hole for threaded connection of the first threaded handle 18. The conveying grooves 10 are provided with a drive mechanism 19.

[0026] The conveying trough 10 is driven by the drive mechanism 19 to move along the slide rail 9, so that the brush 4 and dry ice spray gun 8 can be used for deburring. During use, the fixing component 12 is connected to the conveying trough 10 through the support plate 13. The clamping plate 17 is driven by the first threaded handle 18 to clamp and fix it. At the same time, the movable plug 16 and the fixed plug 15 cooperate with the fixing slot 14 to clamp and limit, so that the fixing component 12 is stably fixed in the conveying trough 10, thereby improving the stability of the fixing component 12 during conveying and processing.

[0027] The fixing assembly 12 also includes symmetrically arranged fixed clamping blocks 20 and symmetrically arranged movable clamping blocks 21. The fixed clamping blocks 20 are symmetrically fixedly connected to the top surface of the support plate 13, and the movable clamping blocks 21 are symmetrically arranged between the fixed clamping blocks 20. A clamping groove 22 is provided between the fixed clamping blocks 20 and the movable clamping blocks 21, and each clamping groove 22 holds a plastic part. The fixing assembly 12 can clamp and fix multiple plastic parts simultaneously, thus facilitating the overall loading and unloading of materials.

[0028] Guide rods 23 are symmetrically fixedly connected to both sides of the fixed clamping block 20. The guide rods 23 slide through the movable clamping block 21. The movable clamping block 21 has a round hole for the guide rods 23 to slide through. Springs 24 are sleeved on the outer side of the guide rods 23 and are arranged between the movable clamping blocks 21.

[0029] The opposite sides of the movable clamping block 21 are fixedly connected with wedge blocks 25, and the wedge blocks 25 are provided with a top block 26 that is adapted to them. The side slope of the top block 26 corresponds to the slope of the wedge block 25.

[0030] A guide post 27 is symmetrically slidably passed through the top block 26. A circular hole is provided on the top block 26 for the guide post 27 to pass through and slide. The guide post 27 is fixedly connected to the top surface of the base plate 1. A second threaded handle 28 is threadedly connected through the middle of the top block 26. A threaded hole is provided in the middle of the top block 26 for the second threaded handle 28 to be threadedly connected. The second threaded handle 28 is rotatably connected to the top surface of the base plate 1.

[0031] The movable clamping block 21 can be elastically opened and closed with the fixed clamping block 20 by the spring 24 and the guide rod 23, so as to elastically clamp the plastic part and form a fixed effect. At the same time, the rotation of the second threaded handle 28 can drive the top block 26 to slide along the guide post 27, so that the movable clamping block 21 is pressed tightly by the cooperation of the top block 26 and the wedge block 25, further strengthening the clamping and fixing of the plastic part and improving the stability of the fixation.

[0032] The drive mechanism 19 includes symmetrically arranged sprockets 29, which are rotatably mounted on the top surface of the base plate 1. A chain 30 is connected to the upper part of the sprockets 29. A connector 31 is fixedly connected to the upper and lower parts of the chain 30. The connector 31 is fixedly connected to the corresponding conveying groove 10. The second mounting cover 3 has a notch that matches the connector 31. The conveying groove 10 is arranged diagonally on the base plate 1. One of the sprockets 29 is fixedly connected to the output end of the second motor 32. The second motor 32 is fixedly mounted on the base plate 1.

[0033] The second motor 32 drives the sprocket 29, which in turn drives the chain 30. This allows the second motor 32 to operate in both directions through the gaps between its components. The connecting piece 31 can then be used to drive the conveyor trough 10 for feeding and returning materials, creating a reciprocating conveying effect. This enables dual-line operation and improves processing efficiency.

[0034] The first motor 5, the ice sprayer 7, and the second motor 32 are all externally connected to power supplies and switches.

[0035] The working principle of this utility model is as follows:

[0036] In use, the movable clamping block 21 is moved outward, and the plastic product to be processed is placed in the clamping groove 22. The movable clamping block 21 is pressed against the fixed clamping block 20 by the spring 24 and the guide rod 23, so that the plastic product is clamped and fixed. The second threaded handle 28 is rotated further, and the rotation of the second threaded handle 28 drives the top block 26 to slide along the guide post 27. Thus, the cooperation between the top block 26 and the wedge block 25 presses the movable clamping block 21 against the plastic part, further strengthening the clamping and fixing of the plastic part and improving the stability of the fixation. At this time, the fixing component 12 with the fixed plastic product is placed in the conveying groove 10, so that the support plate 13 is inserted into the conveying groove 10. The first threaded handle 18 is rotated further, so that the clamping plate 17 cooperates with the inner wall of the conveying groove 10 to clamp and fix the support plate 13. The movable plug 16 and the fixed plug 15 cooperate with the fixing slot 14 to clamp and limit the movement, so that the fixing component 12 is... Stably fixed within the conveying trough 10, the second motor 32 operates in both forward and reverse directions, driving the sprocket 29 via the second motor 32, which in turn drives the chain 30. This allows for convenient feeding and return of materials through the connecting piece 31, creating a reciprocating conveying effect. The forward-conveyed plastic products can be cleaned by the rotating brush 4, which removes larger burrs from the plastic products. Finally, the plastic products enter the second mounting cover 3. The ice sprayer 7 can store dry ice and spray it at high speed from the dry ice spray gun 8 through the ice delivery pipe 6 to remove burrs from the plastic products. Simultaneously, the return conveying trough 10 returns to the front end of the bottom plate 1. At this point, while the plastic products on the feeding conveying trough 10 are being deburred by dry ice, a new fixing component 12 can be installed on the return conveying trough 10. The second motor 32 can then be operated in reverse to create reverse feeding and return, allowing for further processing.

[0037] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
