Specific embodiments

[0022] In order to make the technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] The present utility model provides a technical solution: Refer to Figure 1 - Figure 5 , a green and environment-friendly cutting machine for producing packaging boxes disclosed by the present utility model includes a loading platform 1 and a saw blade 2. The top of the saw blade 2 penetrates through the mounting hole of the loading platform 1 and is in clearance fit with the inner wall of the mounting hole of the loading platform 1. A cooling and collecting assembly 3 is provided at the bottom of the saw blade 2;

[0024] The cooling and collecting assembly 3 includes a water storage box 31. The bottom of the saw blade 2 is inserted into the top opening of the water storage box 31, and the top of the water storage box 31 is fixedly connected to the loading platform 1. A rectangular pipe 32 is provided in the top opening of the water storage box 31, and the bottom of the saw blade 2 is inserted into the top opening of the rectangular pipe 32. The top of the rectangular pipe 32 is fixedly connected to the loading platform 1. The rectangular pipe 32 is in clearance fit with the inner wall of the water storage box 31. An air guide groove 38 is opened at the top side of the loading platform 1 corresponding to the position of the saw blade 2. A driving mechanism 33 is provided on the water storage box 31. An air extraction mechanism 34 is provided jointly on the front side and inside the water storage box 31. A water scraping mechanism 35 is provided jointly on both sides of the saw blade 2.

[0025] In this embodiment, when the improved green and environment-friendly cutting machine for packaging boxes is in use, the driving mechanism 33 drives the saw blade 2 to continuously rotate for cutting the wooden board. At the same time, the air extraction mechanism 34 continuously extracts the gas in the water storage box 31, so that a negative pressure cavity is continuously formed in the water storage box 31. Furthermore, an air flow flowing into the water storage box 31 is continuously formed at the positions of the mounting holes of the carrier table 1 and the air guide grooves 38. And due to the guiding of the rectangular pipe 32, the gas directly flows into the water in the water storage box 31. Thus, the wood powder generated when the saw blade 2 cuts the wooden board can be brought into the water in the water storage box 31 by the air flow, and the wood powder in the air flow is intercepted and stored in the water storage box 31 by the adhesion of the water, which facilitates the collection and recycling of the wood powder, thereby reducing the loss of wood. Moreover, the rotation of the saw blade 2 enables part of the saw blade 2 to pass through the water in the water storage box 31 in turn for continuous cooling of the saw blade 2, avoiding the saw blade 2 from being overheated, resulting in part of the wood powder being damaged and unable to be collected and recycled. The recovery rate of the wood powder is high, greatly reducing the waste of materials.

[0026] In a further preferred embodiment of the present utility model, as Figure 3 shown, the bottom box wall of the water storage box 31 is provided in an inclined shape that warps upward from the middle position to the left and right sides. A valve 36 is provided at the middle position of the bottom end of the water storage box 31, and the top end of the valve 36 fixedly penetrates through the box wall of the water storage box 31, and the top side of the valve 36 is coplanar with the inner bottom wall of the water storage box 31;

[0027] In this embodiment, after the device is used, the operator places an external storage device below the valve 36, and then opens the valve 36. The water in the water storage box 31 carries the wood powder and flows along the inclined inner bottom wall of the storage box towards the valve 36, so that it directly flows out of the water storage box 31 from the valve 36 and falls into the storage device to directly complete the collection and storage of the wood powder. The operation of the device is simple.

[0028] In a further preferred embodiment of the present utility model, as Figure 2 and Figure 5 shown, the driving mechanism 33 includes a rotating shaft 331. The rotating shaft 331 fixedly penetrates through the central position of the saw blade 2, and both ends of the rotating shaft 331 rotatably penetrate through the pipe wall of the rectangular pipe 32 and the box wall of the water storage box 31 through bearings. A motor 332 is fixedly installed on the right side of the water storage box 31, and the driving end of the motor 332 is fixedly connected to the rotating shaft 331;

[0029] In this embodiment, when the above device is in use, the motor 332 is located outside the water storage box 31 and continuously drives the saw blade 2 to rotate through the rotating shaft 331, so as to isolate the motor 332 from external water or water vapor through the water storage box 31, avoiding water or water vapor from invading the motor 332 and causing damage to the motor 332.

[0030] In a further preferred embodiment of the present utility model, as Figure 2 andFigure 3 As shown in the figure, the air extraction mechanism 34 includes an air pump 341, which is fixedly installed on the front side of the water storage box 31. The intake end of the air pump 341 is connected with a conduit 342, and the intake end of the conduit 342 fixedly penetrates the top box wall of the water storage box 31.

[0031] In this embodiment, when the above device is used, the air pump 341 continuously extracts the gas between the rectangular pipe 32 and the inner wall of the water storage box 31 through the conduit 342, so that a negative pressure cavity is continuously formed in the water storage box 31. The outside air continuously penetrates into the rectangular pipe 32 through the gap between the saw blade 2 and the mounting hole, and is introduced into the water at the bottom of the water storage box 31 by the rectangular pipe 32. Then, the wood powder is intercepted and stored in the water in the water storage box 31 through the adhesion of water, avoiding damage to the air pump 341 caused by the adsorption of the wood powder by the air pump 341.

[0032] In a further preferred embodiment of the present utility model, as Figure 3 shown, a plurality of mesh plates 343 are fixedly sleeved on the outer peripheral side of the rectangular pipe 32 from bottom to top, and the distance between adjacent two mesh plates 343 is equal. The outer peripheral wall of the mesh plate 343 is fixedly connected with the box wall of the water storage box 31.

[0033] In this embodiment, after the above air flow flows into the water storage box 31, due to the limited amount of gas passing through the holes in the mesh plate 343, a large amount of air flow diffuses around, and thus passes through the mesh plate 343 from the holes at various positions of the mesh plate 343. Finally, the air flow is split into many small air flows to contact the water, so that the air flow fully contacts the water, avoiding the air flow from wrapping the wood powder and causing the wood powder to be unable to contact the water.

[0034] In a further preferred embodiment of the present utility model, as Figure 3 shown, a pressure limiting valve 37 is provided at the rear side of the water storage box 31, and the drainage end of the pressure limiting valve 37 fixedly penetrates the box wall of the water storage box 31. The drainage end of the pressure limiting valve 37 is located below the mesh plate 343.

[0035] In this embodiment, when the above device is used, the operator first connects the water inlet end of the pressure limiting valve 37 with the drainage end of an external faucet or a water supply device through a water pipe. At this time, due to the pressure difference at both ends of the pressure limiting valve 37, water continuously flows into the water storage tank from the pressure limiting valve 37. And as the water level in the water storage tank rises, the pressure difference at both ends of the pressure limiting valve 37 gradually decreases. After the water level in the water storage tank reaches the threshold value, the pressure difference at both ends of the pressure limiting valve 37 also reaches the threshold value, and thus it automatically closes, and the water in the water pipe will not continue to flow into the water storage tank. And at this time, the bottom of the saw blade 2 is immersed in the water in the water storage tank, so that the water in the water storage tank always stores a specific amount of water, without the operator performing other operations, which facilitates the use of the device.

[0036] In a further preferred embodiment of the present utility model, as Figure 2 、Figure 4 and Figure 5 As shown in Figure 5 , the wiper mechanism 35 includes two soft strips 351. The two soft strips 351 are relatively arranged on both sides of the saw blade 2, and the top sides of each soft strip 351 are coplanar with the top side of the rectangular tube 32. The soft strip 351 is located at the rear side of the rotating shaft 331. A threaded rod 352 is rotatably installed on the soft strip 351, and the threaded rod 352 threadedly penetrates through the tube wall of the rectangular tube 32 and the box wall of the water storage box 31;

[0037] In this embodiment, the rotating saw blade 2 makes part of the position of the saw blade 2 come into contact with water in sequence, so as to continuously cool the saw blade 2. At the same time, as the saw blade 2 rotates, the soft strip 351 slides along both sides of the saw blade 2, so as to scrape off the remaining water or wood powder on the saw blade 2, preventing the rotating saw blade 2 from taking out water or wood powder from the water storage box 31, and thus avoiding unnecessary loss of water and wood powder;

[0038] It should be noted that the above-mentioned soft strip 351 is a plastic strip.

[0039] Working principle: When the improved green and environment-friendly cutting machine for producing packaging boxes is in use, the operator first connects the water inlet end of the pressure-limiting valve 37 to the drain end of an external faucet or a water supply device through a water pipe. At this time, due to the pressure difference at both ends of the pressure-limiting valve 37, water continuously flows into the water storage box from the pressure-limiting valve 37. As the water level in the water storage box rises, the pressure difference at both ends of the pressure-limiting valve 37 gradually decreases. After the water level in the water storage box reaches the threshold value, the pressure difference at both ends of the pressure-limiting valve 37 also reaches the threshold value, so it automatically closes, and the water in the water pipe will not continue to flow into the water storage box. At this time, the bottom of the saw blade 2 is immersed in the water in the water storage box;

[0040] After the above-mentioned water injection operation in the water storage box is completed, the operator rotates the threaded rod 352 to adjust the position of the soft strip 351 so that the soft strip 351 fits the saw blade 2;

[0041] After the position adjustment of the above-mentioned soft strip 351 is completed, the operator starts the motor 332 to continuously drive the saw blade 2 to rotate through the rotating shaft 331. The rotating saw blade 2 makes part of the position of the saw blade 2 come into contact with water in sequence, so as to continuously cool the saw blade 2. At the same time, as the saw blade 2 rotates, the soft strip 351 slides along both sides of the saw blade 2, so as to scrape off the remaining water or wood powder on the saw blade 2;

[0042] While starting the motor 332, the operator synchronously starts the air pump 341. The air pump 341 continuously extracts the gas between the rectangular pipe 32 and the inner wall of the water storage box 31 through the conduit 342, so that a negative pressure cavity is continuously formed in the water storage box 31. Then the outside air continuously flows into the rectangular pipe 32 through the gap between the saw blade 2 and the mounting hole at the position of the air guide groove 38, and is introduced into the water at the bottom of the water storage box 31 through the rectangular pipe 32, and passes through the water in the water storage box 31. At this time, due to the blockage of the air flow by the mesh plate 343, the air flow is split into many small air flows to contact the water, and the wood powder in the air flow is intercepted and stored in the water due to the adhesion of the water;

[0043] After the above-mentioned motor 332 and air pump 341 are started, the operator places the wooden board on the carrier 1, and restricts and positions the wooden board through the limiting mechanism on the carrier 1. Then, the wooden board is pushed towards the saw blade 2 through the slideway on the carrier 1, so that the wooden board is successively divided into the required specifications by the rotating saw blade 2;

[0044] After the device is used up, the operator places the external storage device under the valve 36, and then opens the valve 36. The water in the water storage box 31, carrying the wood powder, directly flows out of the water storage box 31 from the valve 36 and falls into the storage device.

[0045] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
