[0001] The present application relates to the field of cutting equipment, and in particular, to a sample preparation cutting machine device. Background Art

[0002] The cement foamed board is a cement-based lightweight porous inorganic fireproof insulation board prepared by mixing foam prepared with a foaming agent and cement, stirring and mixing, pouring and forming, and then curing. It has a combustion performance of Class A1 and is widely used in building construction. It has the characteristics of high fire resistance, high heat preservation, non-toxic and harmless, long service life, good water resistance, good interface, energy conservation and environmental protection.

[0003] After the cement foamed board is cured by pouring, it is necessary to cut the board body into uniform-sized blocks, and the cut cement foamed board is sent for inspection to ensure the production quality. The cement foamed board is generally cut on a workbench by a band saw. The cement foamed board is placed on the workbench, and the workbench surface moves while cutting, and the moving saw blade cuts the board.

[0004] In view of the above-related technologies, a large amount of dust is generated and dispersed into the air during the cutting of the board, and the large amount of dust in the air will cause great harm to the health of workers and the environment. Summary of the Invention

[0005] In order to improve the problem that a large amount of dust is dispersed into the air during the cutting of the board, the present application provides a sample preparation cutting machine device.

[0006] The sample preparation cutting machine device provided by the present application adopts the following technical solutions:

[0007] A sample preparation cutting machine device includes a base, a workbench surface slidably arranged on the base, a mounting column arranged on one side of the base, and a filtering device arranged on the other side of the base. A band saw is arranged between the base and the mounting column. One side saw blade of the band saw penetrates through the workbench surface. A dust suction hood is arranged on the mounting column. An air pump is arranged in the filtering device, and the air pump is communicated with the filtering device. The dust suction hood is connected to the input end of the air pump through a first suction pipe. A second suction pipe is also communicated with the base, and the second suction pipe is also connected to the input end of the air pump.

[0008] By adopting the above technical solutions, a dust suction hood is arranged above the workbench surface, and the dust suction hood is used to suck the dust escaping above the workbench surface during the cutting process; at the same time, a second suction pipe is also connected to the base. Inevitably, when the saw blade is working, some dust will be driven downward into the base, and the second suction pipe is used to suck the dust in the base; thus, as much dust generated during the cutting process as possible is sucked; the sucked air with dust enters the filtering device for filtering to process the dust; thus, the problem that a large amount of dust escapes into the air during the cutting process, affecting the workshop environment and the health of workers, is improved.

[0009] Optionally, a rodless electric cylinder is arranged on the mounting column, the dust suction hood is connected to the slide of the rodless electric cylinder, and a corrugated pipe is arranged between the dust suction hood and the first suction pipe.

[0010] By adopting the above technical solutions, the rodless electric cylinder is started to drive the dust suction hood to move in the vertical direction. When the cutting work is in progress, the dust suction hood is made to be as close to the workbench surface as possible to avoid excessive dust escaping into the air from the gap between the dust suction hood and the workbench surface; at the same time, the dust suction hood with adjustable height can be applicable to workpieces of different thicknesses to be processed, improving the applicable range.

[0011] Optionally, the dust suction hood is a rectangular hood body with an open lower end. Flow guiding plates are arranged at the lower opening of the dust suction hood and on each side surface of the dust suction hood. The flow guiding plates are slidably arranged on the dust suction hood. A moving member and a guiding member are arranged on the dust suction hood. The moving member is connected to the flow guiding plate and is used to drive the flow guiding plate to approach or move away from the slide. The guiding member is connected to all four flow guiding plates, and the guiding member makes the four flow guiding plates move away from each other when moving downward.

[0012] By adopting the above technical solutions, flow guiding plates are arranged below the dust suction hood. When the moving member drives the flow guiding plates to move downward, the guiding member makes the four flow guiding plates move away from each other, so that the lower part of the dust suction hood is a flared opening with a larger lower end, improving the coverage range of the dust suction hood and further improving the dust suction effect.

[0013] Optionally, the moving member includes a cylinder. The cylinder is arranged on the dust suction hood, and the piston rod of the cylinder extends vertically downward and is connected to the flow guiding plate.

[0014] By adopting the above technical solutions, the cylinder is started, and the piston rod of the cylinder extends or retracts, thereby driving the flow guiding plate to move vertically along the outside of the dust suction hood, achieving the effect of facilitating the driving of the flow guiding plate to move.

[0015] Optionally, the flow guide member includes a connecting ring, a flow guide block, and a purging member. The connecting ring is sleeved on the dust suction hood. The four flow guide plates are all hinged to the connecting ring. The piston rod of the cylinder is connected to the connecting ring. A guiding block with a triangular cross-section is arranged at the lower end of the dust suction hood. The bottom surface of the guiding block faces the ground. The purging member is arranged on the flow guide plate and is used for purging the dust accumulated on the workbench surface.

[0016] By adopting the above technical solution, the bottom surface of the guiding block with a triangular cross-section faces the ground, so that when the connecting ring moves downward, the lower end of the flow guide plate moves downward along the inclined surface of the guiding block, and at the same time, the flow guide plate rotates relative to the connecting ring, achieving the effect of facilitating the mutual separation of the four flow guide plates when the flow guide plate moves downward.

[0017] Optionally, the purging member includes a nozzle, a spring, and a spray pipe. An installation groove is formed on the inner side of the flow guide plate. The nozzle is hinged and installed on the flow guide plate and is located in the installation groove. The spring is located in the installation groove, and one end of the spring is connected to the bottom wall of the installation groove and the other end is connected to the nozzle. The spring makes the lower end of the nozzle always have a tendency to move away from the flow guide plate. One end of the spray pipe is communicated with the output end of the air pump and the other end is communicated with the nozzle.

[0018] By adopting the above technical solution, the upper end of the nozzle is hinged in the installation groove, and the spring makes the lower end of the nozzle always have a tendency to move away from the flow guide plate. When the flow guide plate moves downward to separate from each other, the nozzle rotates away from the flow guide plate. Multiple nozzles all face the inner side of the flow guide plate. At this time, the workbench surface is purged through the nozzles, and the dust deposited on the workbench surface is purged. At the same time, the air with dust and floating dust blown up is sucked through the dust suction hood, achieving the effect of cleaning the dust deposited on the workbench surface.

[0019] Optionally, a corrugated plate is connected between two adjacent flow guide plates.

[0020] By adopting the above technical solution, two adjacent flow guide plates are connected by a corrugated plate, so that the four flow guide plates are connected in a trumpet shape, to a certain extent, preventing the air with dust and floating dust from escaping into the air through the gap between the two flow guide plates.

[0021] Optionally, a cleaning chamber is arranged on the base and directly below the saw blade. One side of the cleaning chamber is communicated with a third suction pipe, and the third suction pipe is communicated with the filtering device.

[0022] By adopting the above technical solution, a cleaning chamber is arranged on the base. The dust brought up by the saw blade will first enter the cleaning chamber. The air with dust in the cleaning chamber is sucked through the third suction pipe, to a certain extent, preventing too much dust from entering the base and affecting the normal operation of related equipment.

[0023] Optionally, a cleaning brush roller is rotatably arranged on the base and within the cleaning cavity, and the cleaning brush roller is arranged on both sides of the saw blade.

[0024] By adopting the above technical solution, cleaning brush rollers are rotatably arranged on both sides of the saw blade within the cleaning cavity. During the movement of the saw blade, the cleaning brush rollers clean the dust adhering to the surface of the saw blade, avoiding the influence on operation caused by a large amount of dust adhering to the saw blade.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. By arranging a dust suction hood above the workbench surface, the dust suction hood is used to suck the dust scattered above the workbench surface during the cutting process; at the same time, a second suction pipe is also connected to the base. Inevitably, when the saw blade is working, it will drive some dust downward into the base, and the second suction pipe is used to suck the dust in the base; thus, as much as possible, the dust generated during the cutting process is sucked; the sucked air with dust enters the filtering device for filtering to process the dust; thus, it improves the problem that a large amount of dust is scattered into the air during the cutting process, affecting the workshop environment and the health of workers.

[0027] 2. The rodless cylinder drives the dust suction hood to move in the vertical direction. During the cutting work, the dust suction hood is made to be as close as possible to the workbench surface to avoid excessive dust escaping into the air through the gap between the dust suction hood and the workbench surface; at the same time, the dust suction hood with adjustable height can be applied to workpieces of different thicknesses to be processed, improving the applicable range.

[0028] 3. A flow guide plate is arranged below the dust suction hood. When the moving member drives the flow guide plate to move downward, the flow guiding member causes the four flow guide plates to move away from each other, so that the lower part of the dust suction hood is a flared opening with a larger lower end, improving the coverage range of the dust suction hood and further enhancing the dust suction effect.

[0036] The following further describes the present application in detail with reference to the Figures 1-5 accompanying drawings.

[0037] An embodiment of the present application discloses a sample preparation cutting machine device. Referring to Figure 1 and Figure 2 , a sample preparation cutting machine device includes a base 1, a workbench surface 2, a mounting column 3, and a filter device 6. The base 1 is a hollow rectangular box body. Two guide rails are installed in parallel on the base 1, and the workbench surface 2 is slidably installed on the base 1 through the guide rails. The mounting column 3 is vertically installed on one side of the base 1, and a band saw machine 4 is vertically installed between the mounting column 3 and the base 1. A cutting slot for the saw blade to move is opened on the workbench surface 2 in the length direction parallel to the guide rails. One side saw blade of the band saw machine 4 vertically passes through the workbench surface 2 through the cutting slot. A dust suction hood 5 is installed on the mounting column 3 and above the workbench surface 2. The opening of the dust suction hood 5 faces downward and is directly opposite to the workbench surface 2. The dust suction hood 5 covers the upper half of the band saw machine 4. The filter device 6 is installed on one side of the base 1, and an air pump is installed inside the filter device 6. A first exhaust pipe 51 is connected and installed at the top of the dust suction hood 5, and the other end of the first exhaust pipe 51 is connected and communicated with the input end of the air pump; a second exhaust pipe 11 is also connected and installed on the base 1, and the other end of the second exhaust pipe 11 is also connected to the air pump.

[0038] During the working process of the cutting machine, a large amount of dust is generated above the workbench surface 2, and at the same time, some dust will enter the base through the cutting slot on the workbench surface 2. The dust suction hood 5 and the first exhaust pipe 51 are used to suck the dust above the workbench surface 2, and the second exhaust pipe 11 is used to suck the dust in the base; the sucked air with dust is transported to the filter device for filtration. Thus, the problem that a large amount of dust will escape into the air during the process of the cutting machine cutting the board, which has a great impact on the workshop environment and the physical health of workers, is improved.

[0039] Referring to Figure 1 and Figure 2, a rodless cylinder 31 is installed on the side of the installation column 3. The cylinder body of the rodless cylinder 31 extends along the length direction of the installation column 3. The dust suction hood 5 is fixedly connected to the slide table of the rodless cylinder 31 through a connecting rod. When the rodless cylinder 31 is started, it drives the dust suction hood 5 to move along the length direction of the installation column 3. Thus, when the cutting machine is working, the dust suction hood 5 can be lowered as close as possible to the plate, thereby to a certain extent avoiding excessive dust from escaping outside the dust suction hood 5. At the same time, when cutting plates of different thicknesses, it can be adjusted adaptively to improve the applicable range.

[0040] Refer to Figure 2 and Figure 3 , the dust suction hood 5 is a rectangular hood body with an opening at the lower end. Guide plates 53 are slidably installed at the lower opening of the dust suction hood 5 and on each side of the dust suction hood 5. The guide plates 53 are rectangular plate bodies, and the four guide plates 53 are slidably installed on the dust suction hood 5. A moving member and a guiding member are installed on the dust suction hood 5. The moving member is connected to all four guide plates 53, and the moving member is used to drive the four guide plates 53 to move synchronously towards or away from the slide table. The guiding member is also connected to all four guide plates 53. When the lower ends of the four guide plates 53 move outside the dust suction hood 5, the lower ends of the four guide plates 53 deviate from each other.

[0041] Refer to Figure 2 , the moving member includes a cylinder 71. The cylinder 71 is provided on multiple edges of the dust suction hood 5. The cylinder body of the cylinder 71 is fixedly connected to the dust suction hood 5, and the piston rod of the cylinder 71 extends vertically downward and is connected to the guide plate 53. When the cylinder 71 is started, the piston rod of the cylinder 71 extends or retracts, driving the four guide plates 53 to slide up and down along the side wall of the dust suction hood 5. When the lower ends of the guide plates 53 move downward outside the dust suction hood 5, the lower ends of the four guide plates 53 deviate from each other, so that the lower end of the dust suction hood 5 is in the shape of a flared opening, increasing the coverage range of the dust suction hood 5. The dust suction hood 5 can suck air in a larger range, further avoiding dust from escaping into the air.

[0042] Refer to Figure 3 and Figure 4, the flow guide member includes a connecting ring 81, a guide block 82, and a purging member 83. The connecting ring 81 is a rectangular rod body with its head and tail connected. The connecting ring 81 is sleeved on the dust suction hood 5 and can slide along the dust suction hood 5. Four flow guide plates 53 are respectively hinged and installed on the four sides of the connecting ring 81, and the flow guide plates 53 are located at the lower end of the connecting ring 81. The ends of the piston rods of multiple cylinders 71 are all connected to the connecting ring 81. A guide block 82 with a triangular cross-section is arranged on the lower side wall of the dust suction hood 5 and between the dust suction hood 5 and the flow guide plates 53, and the bottom surface of the guide block 82 faces the ground. A corrugated plate 54 is connected and arranged between two adjacent flow guide plates 53. The corrugated plate 54 is made of a flexible material. When two adjacent flow guide plates 53 approach or deviate from each other, the corrugated plate 54 deforms accordingly and keeps the connection between two adjacent flow guide plates 53 all the time, so that the four flow guide plates 53 form a flared shape with a closed perimeter. The purging member 83 is arranged on each flow guide plate 53. When the lower end of the flow guide plate 53 moves outside the dust suction hood 5, the purging member 83 is used to purge the dust accumulated on the workbench surface 2.

[0043] When driving the flow guide plate 53 to move downward, the lower end of the flow guide plate 53 moves away from the dust suction hood 5 under the action of the guide block 82, so that the lower ends of the four flow guide plates 53 deviate from each other, making the lower end of the dust suction hood 5 present a flared shape.

[0044] Refer to Figure 3 and Figure 4 , the purging member 83 includes a nozzle 831, a spring 832, and a spray gas pipe 833. A plurality of installation grooves 531 are formed on the inner side of the flow guide plate 53, and the installation grooves 531 are located at the lower part of the flow guide plate 53. The nozzle 831 is located in the installation groove 531, and the upper end of the nozzle 831 is hinged to the two side walls of the installation groove 531. The spring 832 is located in the installation groove 531. One end of the spring 832 is fixedly connected to the bottom wall of the installation groove 531, and the other end of the spring 832 is connected to the nozzle 831. The spring 832 makes the lower end of the nozzle 831 always tend to move away from the flow guide plate 53. One end of the spray gas pipe 833 is communicated with the output end of the air pump, and the other end is wound around outside the four flow guide plates 53 and is communicated with a plurality of nozzles 831. The spray gas pipe 833 is a flexible pipe. During the process of the four flow guide plates 53 unfolding and folding, the spray gas pipe 833 deforms accordingly.

[0045] During the process of the flow guide plate 53 moving downward, when the installation groove 531 on the flow guide plate 53 moves outside the range of the dust suction hood 5, at this time, the nozzle 831 moves away from the flow guide plate 53 under the action of the spring 832. The nozzle 831 extends obliquely downward, and a plurality of nozzles 831 all face the center of the workbench surface 2, that is, the cutting place of the saw blade and the plate. Thus, the dust accumulated on the workbench surface 2 is purged through the nozzle 831, and the dust and dirt generated by the purging are sucked through the dust suction hood 5.

[0046] Refer toFigure 5 , a cleaning chamber 12 is arranged on the base 1 and directly below the saw blade. The cleaning chamber 12 is partitioned by a partition plate 12 that is inclined and arranged on the base 1, and a slit for the saw blade to pass through is formed on the partition plate 15. A third air extraction pipe 14 is connected and installed on the base 1 and on one side of the cleaning chamber 12, and the other end of the third air extraction pipe 14 is communicated with the filtering device 6. A cleaning brush roller 13 is rotatably arranged in the cleaning chamber 12 on the base 1. The cleaning brush rollers 13 are arranged on both sides of the saw blade, and the cleaning brush rollers 13 on both sides of the saw blade are respectively in contact with the two side surfaces of the saw blade. A cleaning chamber 12 is isolated in the base 1, and the dust raised by the saw blade first enters the cleaning chamber 12, and the third air extraction pipe 14 sucks the air with dust in the cleaning chamber 12. At the same time, the saw blade will adhere to dust during the working process, and the cleaning brush roller 13 is used to clean the dust on the saw blade.

[0047] The implementation principle of the sample preparation cutting machine device in the embodiment of the present application is as follows: during the working process of the cutting machine, a large amount of dust is generated above the workbench surface 2, and at the same time, some dust will enter the base through the cutting slit on the workbench surface 2. The dust suction hood 5 and the first air extraction pipe 51 are used to suck the dust above the workbench surface 2, and the second air extraction pipe 11 is used to suck the dust in the base; the sucked air with dust is transported to the filtering device for filtering. Thus, during the process of the cutting machine cutting the board, a large amount of dust will escape into the air, which has a greater impact on the workshop environment and the physical health of workers.

[0048] Finally, it should be noted that: in the description of the present application, it should be noted that the orientation or positional relationship indicated by the terms "vertical", "upper", "lower", "horizontal", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application.

[0049] The above are all the preferred embodiments of the present application.
