Description

Technical Field

[0001] This utility model relates to the field of rubber hose processing technology, specifically to a trimming device for rubber hose production. Background Technology

[0002] Rubber hoses undergo injection molding during processing, resulting in burrs on the surface that need to be trimmed. Manual deburring is labor-intensive and inefficient, while using mechanical trimming machines like cryogenic trimming machines is too costly, negatively impacting production efficiency. Furthermore, existing trimming machines are not suitable for trimming rubber hoses of different diameters.

[0003] To address this problem, we designed a new trimming device for rubber hose production. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a trimming device for rubber hose production. The specific solution is as follows: A trimming device for rubber hose production includes a base frame. A grinding assembly, a tensioning assembly, and a winding mechanism are sequentially arranged on the base frame according to the rubber hose transport direction. The grinding assembly includes a pair of upright plates, on which a cylinder is rotatably mounted. One upright plate has a drive motor that drives the cylinder to rotate via a gear transmission structure. The cylinder has an air port with a valve core inside. An air bladder is located inside the cylinder, and an abrasive layer is formed on the inner surface of the air bladder. The winding mechanism includes a support frame fixed to the base frame, on which a winding reel driven by a servo motor is rotatably mounted.

[0005] Based on the above, the tensioning assembly includes a pair of uprights mounted on the base frame. Each upright is rotatably mounted on a swing frame. The swing frame is provided with a pin that rotates with the upright. A pressure roller is rotatably mounted on the pair of swing frames. The pair of swing frames are also provided with a counterweight rod. Both ends of the counterweight rod are provided with screws that pass through the stroke grooves on the swing frame. Fastening bolts are screwed onto the screws.

[0006] Based on the above, guide components are provided on both sides of the grinding assembly on the base frame. The guide components include brackets fixed on the base frame, and the top of the brackets is provided with guide rings for the rubber tube.

[0007] Based on the above, both the drive motor and the servo motor are electrically connected to the controller mounted on the base frame.

[0008] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model has the following advantages: The trimming device for rubber tube production provided by this utility model has a structural design that facilitates efficient grinding of the surface of rubber tubes of different diameters. Furthermore, during the grinding process, the rubber tube can be tensioned to further ensure the grinding effect. Attached Figure Description

[0013] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0014] Example like Figure 1-3 As shown, this utility model provides a trimming device for producing rubber tubes 17, including a base frame 1. The base frame 1 is provided with a grinding component 2, a tensioning component 12 and a winding mechanism in sequence according to the transmission direction of the rubber tube 17. The grinding component 2 includes a pair of upright plates 3, and a cylinder 4 is rotatably mounted on the pair of upright plates 3. One of the upright plates 3 is provided with a drive motor 6. The drive motor 6 drives the cylinder 4 to rotate through a gear transmission structure 7. The cylinder 4 is provided with an air port 5. An air valve core 5-1 is provided in the air port 5. An air bladder 4-1 is provided in the cylinder 4. An abrasive layer 4-2 is provided on the inner surface of the air bladder 4-1. The winding mechanism includes a support frame 13 fixed on the base frame 1. A winding reel 14 driven by a servo motor 15 is rotatably mounted on the support frame 13.

[0015] The tensioning assembly 12 includes a pair of uprights 11 mounted on the base frame 1. Each upright 11 is rotatably mounted on a swing frame 12-1. The swing frame 12-1 is provided with a pin 12-2 rotatably mounted with the upright 11. A pressure roller 12-6 is rotatably mounted on the pair of swing frames 12-1. The pair of swing frames 12-1 are also provided with a counterweight rod 12-4. Both ends of the counterweight rod 12-4 are provided with screws that pass through the stroke groove 12-3 on the swing frame 12-1. Fastening bolts 12-5 are screwed onto the screws.

[0016] The base frame 1 is provided with guide components on both sides of the grinding assembly 2. The guide components include brackets 9 fixed on the base frame 1, and the top of the brackets 9 is provided with guide rings 10 for the rubber tube 17.

[0017] To facilitate the operation of the device, the drive motor 6 and servo motor 15 are electrically connected to the controller 16 mounted on the base frame 1.

[0018] It should be noted that the abrasive layer 4-2 is formed by ceramic particles fixed to the surface of the airbag 4-1 by an adhesive.

[0019] The specific working principle of this utility model is as follows: First, the rubber tube 17 is passed through the guide ring 10, the cylinder 4, and another guide ring 10. Then, the free end of the rubber tube 17 is fixedly connected to the winding reel 14, and the rubber tube 17 is pressed by the pressure roller 12-6. At the same time, the position of the counterweight rod 12-4 is adjusted. Then, air is pumped into the valve to make the air bag 4-1 fit against the surface of the rubber tube 17. Then, the drive motor 6 is started, and the drive motor 6 drives the cylinder 4 to rotate. Then, the abrasive layer 4-2 begins to polish the surface of the rubber tube 17. As the servo motor 15 runs, the rubber tube 17 is wound up by the winding reel 14.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
