Description

Technical Field

[0001] This utility model belongs to the field of heat shrink tubing processing technology, and more specifically, it relates to a protective device for heat shrink tubing processing. Background Technology

[0002] The small amount of organic waste gas generated during the heating process of heat shrink tubing is collected by the gas collection device built into the protective cover, and then discharged after being treated by activated carbon adsorption or catalytic combustion. This avoids environmental pollution and protects the health of workers. Existing protective devices for heat shrink tubing processing require manual replacement of filter blocks periodically when using the gas collection device. Since the lifespan of a single filter block is limited, the replacement frequency is relatively frequent, which is time-consuming and labor-intensive. Therefore, a protective device for heat shrink tubing processing is proposed. Utility Model Content

[0019] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a protective device for heat shrink tubing processing, including a protective cover 1, a bracket 2 fixed to the top surface of the protective cover 1, the bracket 2 having a cross-shaped structure, an upper mounting bracket 3 and a lower mounting bracket 4 fixed to the front side of the bracket 2, an upper ventilation pipe 5 and a lower ventilation pipe 6 respectively fixed to the inner side of the upper mounting bracket 3 and the lower mounting bracket 4, a ventilation fan 12 fixed to the upper end of the upper ventilation pipe 5, a limit ring 7 fixed to the inner bottom of the upper ventilation pipe 5 and the inner top of the lower ventilation pipe 6, a storage pipe 8 and a waste pipe 9 respectively fixed to the inner side of the upper mounting bracket 3 and the lower mounting bracket 4, a storage pipe 8 and a waste pipe 9 respectively, a plurality of filter blocks 10 provided inside the storage pipe 8, a cover 11 threadedly connected to the inner bottom of the waste pipe 9, a rack 13 fixed to the rear side of the bracket 2, and a sliding opening on the rear side of the bracket 2. The inner side of the groove 14 is slidably connected to the slider 15. The front side of the slider 15 is fixed to the movable plate 16. The top surface of the movable plate 16 is provided with a round hole 17. The top surface of the movable plate 16 is slidably in contact with the baffle 18. The bottom surface of the slider 15 is fixed to the motor 19. The output end of the motor 19 extends through the bottom surface of the slider 15 to the top surface and is coaxially fixed to the gear 20. The upper mounting bracket 3 is located above the lower mounting bracket 4. The upper ventilation pipe 5 is located above the lower ventilation pipe 6. The lower end of the upper ventilation pipe 5 corresponds to the upper end of the lower ventilation pipe 6. The lower end of the lower ventilation pipe 6 is connected to the inside of the protective cover 1. The diameter of the round hole 17 is slightly larger than the diameter of the filter block 10. The rear side of the baffle 18 is fixedly connected to the front side of the bracket 2. The outer side of the gear 20 is meshed with the outer side of the rack 13. During use, negative pressure is generated by the ventilation fan 12, causing air to flow from the protective cover 1 into the lower ventilation pipe 6. Then, it flows through the filter block 10 into the upper ventilation pipe 5, and finally exits through the ventilation fan 12, thus filtering out the toxic gases produced by the extruder inside the protective cover 1. When the filter block 10 reaches the end of its service life, the gear 20 on the motor 19 rolls along the rack 13, thereby driving the circular hole 17 on the movable plate 16 to move from below the upper ventilation pipe 5 to above the waste pipe 9. Under gravity, the discarded filter block 10 falls into the waste pipe 9. Then, the circular hole 17 moves from above the waste pipe 9 to below the storage pipe 8, and the filter block 10 in the storage pipe 8 falls into the circular hole 17. Finally, the circular hole 17 returns to below the upper ventilation pipe 5, thus completing the automatic replacement of the filter block 10. Through the above process, the filter block 10 replacement can be completed automatically, solving the problem that when using a gas collection device, manual periodic replacement of filter blocks is required, which is time-consuming and labor-intensive due to the limited lifespan of a single filter block.

[0022] The specific usage and function of this embodiment: When this utility model is in use, the ventilation fan 12 generates negative pressure, causing air to flow from the protective cover 1 into the lower ventilation pipe 6, and then through the filter block 10 into the upper ventilation pipe 5, and finally discharged through the ventilation fan 12, thereby filtering out the toxic gas generated by the extruder in the protective cover 1. When the filter block 10 reaches the end of its service life, the gear 20 on the motor 19 rolls along the rack 13, thereby driving the round hole 17 on the movable plate 16 to move from below the upper ventilation pipe 5 to above the waste pipe 9. Under the action of gravity, the discarded filter block 10 falls into the waste pipe 9. Then, the round hole 17 moves from above the waste pipe 9 to below the storage pipe 8, and the filter block 10 in the storage pipe 8 falls into the round hole 17. Finally, the round hole 17 returns to below the upper ventilation pipe 5, thus completing the automatic replacement operation of the filter block 10.

[0023] 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.
