Abstract
Description
Technical Field
[0001] This utility model relates to the field of building formwork processing technology, and in particular to a device for preventing wood chip splashing during building formwork processing. Background Technology
[0002] During the processing of construction formwork, operations such as cutting, drilling, and sanding generate a large amount of sawdust. This sawdust often flies out at high speed, causing serious pollution to the surrounding working environment, affecting the operator's vision, and reducing work efficiency. Moreover, the sawdust may fly into the operator's eyes, respiratory tract, and other parts, posing a great safety hazard to the operator's health.
[0003] While traditional solutions often rely on operators wearing protective eyewear and masks, these measures cannot fundamentally solve the problem of sawdust splattering throughout the work area and are ineffective in maintaining a good processing environment. Therefore, it is necessary to design a specialized sawdust-splatter-prevention device for construction formwork processing to improve this situation. Utility Model Content
[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a device for preventing wood chip splashing during the processing of building templates.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0023] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a wood chip anti-splashing device for building formwork processing, including a workbench 1, a support frame 2 above the workbench 1, a T-shaped block 10 fixedly connected to the surface of the support frame 2, a T-shaped groove 11 formed on the surface of the workbench 1, the T-shaped block 10 inserted into the T-shaped groove 11, a threaded hole 5 formed on the surface of the support frame 2, a screw 6 threadedly connected to the inside of the threaded hole 5, a handle 8 fixedly connected to the top of the screw 6, and a protective cover 18 rotatably connected to the bottom of the screw 6. A motor 3 is connected to the output end of the motor 3, and a saw disc 4 is fixedly connected to the output end of the motor 3. The saw disc 4 is located inside the protective cover 18. A handle sleeve 9 is fitted on the surface of the handle 8. The handle sleeve 9 is made of elastic rubber. A guide rod 7 is fixedly connected to the surface of the protective cover 18. A round hole 17 is opened on the surface of the support frame 2. The guide rod 7 is inserted into the round hole 17. A soundproof cover 19 is provided on the surface of the protective cover 18. The soundproof cover 19 is located on the outer surface of the protective cover 18. A guide rod 12 is fixedly connected to the surface of the protective cover 18. The guide rod 12 and the saw disc 4 are on the same plane.
[0024] In this embodiment, by covering the protective cover 18 above the electric saw disc 4, wood chips are prevented from flying out and causing environmental pollution when cutting the board. At the same time, by turning the handle 8, the screw 6 is rotated, which adjusts the height of the protective cover 18. This allows the height of the protective cover 18 to be adjusted according to the thickness of the board to better prevent wood chips from flying out, improve the cleanliness of the working environment, and reduce the harm of wood chips to the health of operators. The soundproof cover 19 covering the outside of the protective cover 18 can play a certain role in noise reduction when the electric saw disc 4 is cutting the board, avoiding noise pollution. The guide rod 7 slides in the round hole 17, which can guide and limit the movement of the protective cover 18 when it moves up and down, preventing the protective cover 18 from rotating and affecting the use effect. The handle sleeve 9 set on the surface of the handle 8 can prevent the palm from directly contacting the handle 8 and causing friction and hand discomfort when turning the handle 8.
[0025] Example 2: As Figure 3 As shown, an L-shaped guide plate 13 is fixedly connected to the surface of the workbench 1, a collection box 16 is provided at the end face of the workbench 1, a T-shaped groove 14 is provided on the surface of the workbench 1, and a T-shaped block 15 is fixedly connected to the surface of the collection box 16. The T-shaped block 15 is locked inside the T-shaped groove 14.
[0026] In this embodiment, the sawdust accumulated on the workbench 1 is swept into the interior of the L-shaped guide plate 13, and then the sawdust in the L-shaped guide plate 13 is swept into the interior of the collection box 16, thus achieving the purpose of collecting the sawdust on the workbench 1. This facilitates the centralized processing of the sawdust later and improves the convenience of sawdust cleaning. By locking the T-shaped block 15 on the collection box 16 into the interior of the T-shaped groove 14 on the workbench 1, the purpose of fixing the collection box 16 is achieved, and on the other hand, it also facilitates the disassembly of the collection box 16.
[0027] The working principle of this embodiment is as follows: First, the motor 3 is started, and its output drives the saw disc 4 to rotate. Then, the board is placed on the workbench 1. The guide rod 12 on the protective cover 18 ensures that the position to be cut on the board is parallel and aligned with the guide rod 12, allowing the saw disc 4 to cut the board more precisely. By covering the saw disc 4 with the protective cover 18, sawdust is prevented from flying out during cutting, thus avoiding environmental pollution. When the distance between the protective cover 18 and the workbench 1 needs to be adjusted according to the thickness of the board, the handle 8 is turned. The handle 8 drives the screw 6 to rotate within the threaded hole 5 on the support frame 2. Simultaneously, the screw 6 rotates, causing the protective cover 18 to move up and down. The handle sleeve 9 on the surface of the handle 8 prevents direct contact and friction between the palm and the handle 8 during rotation, thus avoiding hand discomfort. During the up-and-down movement of the protective cover 18, the guide rod 7 slides within the round hole 17, providing guidance and limiting during its movement. The soundproof cover 19, which covers the outside of the protective cover 18, serves to prevent the protective cover 18 from rotating and affecting the performance. When the electric saw disc 4 is cutting the board, the soundproof cover 19 can reduce noise and prevent noise pollution. When sawdust accumulates on the workbench 1, it can be swept into the L-shaped guide plate 13 and then into the collection box 16, thus collecting the sawdust on the workbench 1. This facilitates centralized processing of the sawdust and improves the convenience of sawdust cleaning. The T-shaped block 15 on the collection box 16 is fixed inside the T-shaped groove 14 on the workbench 1. On the other hand, when it is necessary to centrally process the sawdust in the collection box 16, the collection box 16 can be lifted upwards to release the T-shaped block 15 from the T-shaped groove 14, making it easy to disassemble the collection box 16. Then, the sawdust in the collection box 16 can be centrally processed.
[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
