Description

Technical Field

[0001] This utility model relates to the field of dust-free saw table technology, and in particular to a simple inverted dust-free saw table that can be assembled quickly. Background Technology

[0002] During formwork construction, wooden formwork and square timber need to be cut to the required dimensions using a sawing table. Since commercially available dust-free sawing tables are expensive, and a large number of sawing tables are needed on-site, purchasing only commercially available sawing tables would significantly increase construction costs. In actual on-site construction, the sawing tables used are generally homemade from materials such as small woodworking cutting machines, wooden formwork, and square timber. However, these traditional homemade sawing tables have a simple structure and cannot quickly and effectively collect sawdust generated during processing. This results in sawdust entering the beam and column formwork, posing a potential quality hazard to the concrete appearance.

[0003] A dust-free saw table with a master-slave saw is disclosed in Chinese patent document CN201920918113.8. This dust-free saw table includes a fixed platform and a bracket hinged to the fixed platform. A fixed plate is fixedly installed on the lower side of the fixed platform, and an electric saw assembly is mounted on the fixed plate. An exhaust fan is mounted on the bracket. The electric saw assembly includes a female saw blade and a female saw blade. A first protective cover is fixedly installed on the outer side of the female saw blade. The first protective cover has a first dust suction hole, and a first flexible hose is inserted into the first dust suction hole. A second protective cover is fixedly installed on the outside of the saw blade. The second protective cover is equipped with a second dust suction hole, which is connected to a second flexible hose. The exhaust fan is equipped with an air inlet and an air outlet. The air inlet is divided into two paths, one of which is connected to the first flexible hose and the other of which is connected to the second flexible hose. The air outlet is connected to a dust collection bag. The saw table has a compact structure and reasonable design. The multi-directional dust removal mechanism effectively solves the problem of sawdust diffusion. However, the dust-free saw table with a mother-daughter saw is heavy and inconvenient to move. Moreover, the structure is complex and the production cost is high.

[0004] To address the shortcomings of the existing technology, providing a simple, inverted, dust-free saw table that can be assembled quickly is a problem worthy of research. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of a simple structure that cannot quickly and effectively collect sawdust waste generated during processing, and to provide a simple, quick-assembly, inverted dust-free saw table, thereby improving construction efficiency and reducing the cost of purchasing ready-made dust-free saw tables.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A simple, inverted, dust-free saw table that can be assembled quickly includes a saw table, a saw kerf opened on the saw table, and a circular saw disc rotatably connected to the saw kerf. It also includes a dust cover disposed above the circular saw disc, support mechanisms disposed on both sides of the dust cover, and a dust collection mechanism disposed above the dust cover.

[0008] A servo motor is fixedly connected to one side below the saw kerf. The output end of the servo motor is fixedly connected to the rotating shaft of the circular saw disc. The top height of the circular saw disc is higher than the top height of the saw table. The servo motor drives the circular saw disc to rotate and cut the wooden board.

[0009] The bottom of the dust cover is open, and the length of the bottom opening of the dust cover is greater than the width of the circular saw blade extending out of the saw kerf. The dust cover is made of transparent glass or transparent plastic. The dust cover blocks the wood chips generated during the sawing process of the circular saw blade, preventing the wood chips from flying around and affecting the operation time limit, and keeping the construction environment clean.

[0010] The support mechanism includes a support plate fixedly connected to the inside of the rear side of the saw kerf, a rotating shaft rotatably connected between the top of the support plate and the dust cover, and a torsion spring sleeved on one end of the rotating shaft.

[0011] The torsion spring causes the front end of the dust cover to tilt downwards. The torsion spring is greater than the total weight of the dust cover and the suction connection pipe. The torsion spring keeps the dust cover tilted forward under the action of the torsion, so that the dust cover can be slightly adjusted in angle as needed, while maintaining a stable state of covering the circular saw disc.

[0012] The thickness of the support plate is no greater than the thickness of the circular saw blade, so that the support plate can pass through the gap of the wood board being cut, thus avoiding the support plate affecting the normal feed of the wood board during cutting.

[0013] The support mechanism also includes guide wheels rotatably connected to both sides of the front end of the dust cover. The bottom height of the guide wheels is lower than the bottom height of the dust cover, and the distance between the bottom of the guide wheels and the bottom of the dust cover is less than one centimeter. When cutting the wood board, the guide wheels can press against the wood board under the torque of the torsion spring, limiting the position of the wood board and improving the stability of the wood board during cutting.

[0014] The dust collection mechanism includes a wood chip vacuum cleaner located on one side of the saw table and a telescopic hose located on the top of the dust cover.

[0015] One end of the telescopic hose is connected to the top opening of the dust cover, and the other end of the telescopic hose is connected to the suction pipe of the wood chip vacuum cleaner. The wood chip vacuum cleaner will absorb and collect the wood chips collected by the dust cover, keeping the inside of the dust cover clean and preventing the accumulation of wood chips inside the dust cover from affecting the normal cutting of the wood board.

[0016] Support legs are fixedly connected to the four corners of the bottom of the saw table, and support frames are fixedly connected to both sides below the saw kerf. The circular saw disc is rotatably connected between the support frames; the support frames are also fixed to the saw table.

[0017] Positive and beneficial effects:

[0018] 1. This quick-assembly, simple inverted dust-free saw table has a simple structure, requires less assembly materials, is easy to disassemble, and greatly reduces investment costs. It can quickly and effectively collect sawdust generated during processing, reducing the potential for defects in the appearance of concrete caused by sawdust waste. Furthermore, the required assembly materials such as templates and timber can be quickly obtained and assembled on the construction site. Assembly equipment such as cutting machines and vacuum cleaners can also be reused separately, offering greater flexibility.

[0019] 2. This quick-assembly, easy-to-use, inverted dust-free saw table features a dust cover that blocks sawdust generated during the circular sawing process, preventing sawdust from flying around and affecting operation time. This keeps the construction environment clean, and the dust cover also protects the top of the circular saw, preventing the safety hazards caused by the top of the circular saw being exposed during rotation, thus improving construction safety.

[0020] 3. This quick-assembly, simple inverted dust-free saw table uses a wood chip vacuum cleaner to collect the wood chips collected by the dust cover, keeping the inside of the dust cover clean and preventing wood chips from accumulating inside the dust cover and affecting the normal cutting of the wood planks.

Detailed Implementation

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0031] like Figures 1 to 6 As shown, a simple inverted dust-free saw table that can be assembled quickly includes a saw table 1, a saw kerf 2 opened on the saw table 1, and a circular saw disc 3 rotatably connected in the saw kerf 2. It also includes a dust cover 4 disposed above the circular saw disc 3, support mechanisms 5 disposed on both sides of the dust cover 4, and a dust collection mechanism 6 disposed above the dust cover 4.

[0032] like Figure 4 As shown, a servo motor 7 is fixedly connected to one side below the saw kerf 2. The output end of the servo motor 7 is fixedly connected to the rotating shaft of the circular saw disc 3. The top height of the circular saw disc 3 is higher than the top height of the saw table 1. By setting the servo motor 7 below the saw kerf 2, it drives the circular saw disc 3 to rotate and cut the wooden board.

[0033] like Figures 5 to 6 As shown, the bottom of the dust cover 4 is open, and the length of the bottom opening of the dust cover 4 is greater than the width of the circular saw disc 3 extending out of the saw kerf 2. The dust cover 4 is made of transparent glass or transparent plastic. By setting the dust cover 4 above the circular saw disc 3, the sawdust generated during the sawing process of the circular saw disc 3 is blocked, preventing the sawdust from flying around and affecting the operation time limit, keeping the construction environment clean. The dust cover 4 can also protect the top of the circular saw disc 3, avoiding the safety hazards of the top of the circular saw disc 3 being exposed during rotation, and improving construction safety. Making the dust cover 4 transparent allows the operator to easily observe the rotation of the circular saw disc 3 and the collection of sawdust inside the dust cover 4, which is helpful for judging the construction situation based on the observation information.

[0034] Furthermore, the dust cover 4 is made of transparent explosion-proof glass, which makes it transparent while having strong impact resistance, so as to prevent wood chips or circular saw disc 3 from damaging the dust cover 4. Example 2

[0035] like Figures 2 to 6 As shown, the support mechanism 5 includes a support plate 501 fixedly connected to the inside of the rear side of the saw kerf 2, a rotating shaft 502 rotatably connected between the top of the support plate 501 and the dust cover 4, and a torsion spring 503 sleeved on one end of the rotating shaft 502.

[0036] like Figures 2 to 6 As shown, the torque of the torsion spring 503 causes the front end of the dust cover 4 to tilt downwards. The torque of the torsion spring 503 is greater than the total weight of the dust cover 4 and the suction connecting pipe. By setting the torsion spring 503 on the rotating shaft 502, the dust cover 4 is kept tilted forward under the action of torque, so that the dust cover 4 can be slightly adjusted in angle as needed, while maintaining a stable state of covering the circular saw disc 3. The torque of the torsion spring 503 is limited to be sufficient to support the weight of the dust cover 4 and the pipe above.

[0037] like Figures 5 to 6 As shown, the thickness of the support plate 501 is no greater than the thickness of the circular saw blade 3. By limiting the thickness of the support plate 501, the support plate 501 can pass through the gap of the wood board being cut, thus avoiding the support plate 501 affecting the normal feed when the wood board is being cut.

[0038] like Figures 2 to 3 As shown, the support mechanism 5 also includes guide wheels 504 rotatably connected to both sides of the front end of the dust cover 4. The bottom height of the guide wheels 504 is lower than the bottom height of the dust cover 4, and the distance between the bottom of the guide wheels 504 and the bottom of the dust cover 4 is less than one centimeter. By setting guide wheels 504 at the front end of the dust cover 4, when cutting the wood board, the guide wheels 504 can be pressed onto the wood board under the torque of the torsion spring 503, limiting the wood board and improving the stability of the wood board during cutting. In addition, the guide wheels 504 supporting the wood board can support the front end of the dust cover 4, improving the stability of the dust cover 4. Example 3

[0039] like Figures 2 to 6 As shown, the dust collection mechanism 6 includes a wood chip vacuum cleaner 601 disposed on one side of the saw table 1, and a telescopic hose 602 disposed on the top of the dust cover 4.

[0040] like Figures 2 to 6As shown, one end of the telescopic hose 602 is connected to the top opening of the dust cover 4, and the other end of the telescopic hose 602 is connected to the suction pipe of the wood chip vacuum cleaner 601. By installing the wood chip vacuum cleaner 601 with the telescopic hose 602 on the top of the dust cover 4, the wood chip vacuum cleaner 601 can absorb and collect the wood chips collected by the dust cover 4, keeping the inside of the dust cover 4 clean and preventing the accumulation of wood chips inside the dust cover 4 from affecting the normal cutting of the wood board. In addition, the airflow generated by the wood chip vacuum cleaner 601 when absorbing wood chips can cool the wood board and the circular saw disc 3, preventing the wood board and the circular saw disc 3 from rubbing against each other during the cutting process, which could cause the temperature to be too high and ignite the wood board or wear down the circular saw disc 3.

[0041] Furthermore, as the dust cover 4 rotates with the rotating shaft 502, the telescopic hose 602 can bend and adapt according to the rotation of the dust cover 4, so that the dust cover 4 remains connected to the dust collection pipe of the wood chip vacuum cleaner 601 during the rotation.

[0042] This dust-free saw table has a simple structure, requires few assembly materials, is easy to disassemble, and greatly reduces investment costs. It can quickly and effectively collect sawdust generated during processing, reducing the potential for defects in the appearance of concrete caused by sawdust waste. Furthermore, the required assembly materials such as templates and timber can be quickly obtained and assembled on the construction site, and the assembly equipment such as the cutting machine and vacuum cleaner can also be reused separately, offering greater flexibility.

[0043] like Figures 1 to 4 As shown, support legs 8 are fixedly connected to the four corners of the bottom of the saw table 1, and support frames 9 are fixedly connected to both sides below the saw kerf 2. The circular saw disc 3 is rotatably connected between the support frames 9. The support frames (9) are also fixed to the saw table (1) to achieve the limiting and fixing of the circular saw disc 3.

[0044] The working principle of this utility model is as follows:

[0045] S1. Dust cover 4 blocks the wood chips generated during the sawing process of circular saw disc 3, preventing wood chips from flying around and affecting the operation time limit;

[0046] S2, the torsion spring 503 keeps the dust cover 4 tilted forward under the action of torsion, so that the dust cover 4 can be slightly adjusted as needed, while stably maintaining the state of covering the circular saw disc 3.

[0047] S3. When cutting the wood board, the object to be cut comes into contact with the circular saw disc 3 and is slowly pushed towards the support plate 501 by the guide wheel 504. Under the torque of the torsion spring 503, the guide wheel 504 can press against the wood board, limiting the wood board and improving the stability of the wood board during cutting.

[0048] S4. The wood chip vacuum cleaner 601 absorbs and collects the wood chips collected by the dust cover 4, keeping the inside of the dust cover 4 clean and preventing the accumulation of wood chips inside the dust cover 4 from affecting the normal cutting of the wood board.

[0049] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
