[0028] Please refer to Figure 1 , Figure 1 A schematic diagram of the three-dimensional structure of an air-blowing cleaning device for PMMA plates is shown. The air-blowing cleaning device includes a transmission mechanism 10, a first pneumatic mechanism 20 and a second pneumatic mechanism 30. The first pneumatic mechanism 20 and the second pneumatic mechanism 30 are respectively arranged on both sides of the transmission mechanism 10 in the height direction, and the air outlet directions of the first pneumatic mechanism 20 and the second pneumatic mechanism 30 are inclined to the moving direction of the plate. The transmission mechanism 10 is used to transmit the plate so that the first pneumatic mechanism 20 and the second pneumatic mechanism 30 blow air to the two opposite surfaces of the plate respectively. Specifically, the transmission mechanism 10 can be, for example, a conveyor belt, chain, rope, pulley, etc. commonly used in a workshop, which is not limited here. In the illustrated structure, the first pneumatic mechanism 20 and the second pneumatic mechanism 30 are respectively arranged directly below and directly above the transmission mechanism 10, and the air outlet directions of both are toward the transmission mechanism 10, that is, inclined to the moving direction of the plate.

[0029] Please refer to Figure 2 , Figure 2 The schematic diagram of the three-dimensional structure of an air-blowing cleaning device for PMMA sheet in cooperation with the sheet 90 is shown. In one embodiment, the conveying mechanism 10 can be arranged at the end of the sheet 90 cutting production line, and the cut sheet 90 is transported to the conveying mechanism 10. In the process of the conveying mechanism 10 transporting the sheet 90, the first pneumatic mechanism 20 and the second pneumatic mechanism 30 blow air to the two opposite surfaces of the sheet 90 respectively. After the sheet 90 is transported from the conveying mechanism 10, the sawdust or debris on the two surfaces of the sheet 90 have been completely cleaned, and the sheet 90 with a neat appearance is directly obtained, which improves the convenience of the staff on the workshop site to perform the subsequent packaging process.

[0030] Thus, according to the aforementioned air-blowing cleaning device, the enterprise does not need to employ manual labor to operate, thus reducing the enterprise cost, fully automatically performing the surface cleaning process of the plate 90, improving the delivery efficiency of the plate 90, and eliminating the need to find an additional open space in the production workshop for employees to perform the blowing process on the surface of the plate 90, thus saving the effective use space of the production workshop. Among them, the number and relative position of the first pneumatic mechanism 20 and the second pneumatic mechanism 30 can be set according to actual needs in the workshop site to obtain the best cleaning strength and cleaning efficiency.

[0031] Optionally, the first pneumatic mechanism 20 and the second pneumatic mechanism 30 are arranged at intervals along the length direction of the plate 90. Specifically, in this embodiment, the length direction of the plate 90 is also the length direction of the transmission mechanism 10. In the illustrated structure, the first pneumatic mechanism 20 is arranged near the feeding end of the transmission mechanism 10, and the second pneumatic mechanism 30 is arranged near the delivery end of the transmission mechanism 10. In actual implementation, when the plate 90 enters the transmission mechanism 10 from the feeding end, the first pneumatic mechanism 20 first blows and cleans one surface (i.e., the lower surface) of the plate 90. When the plate 90 continues to move and gradually approaches the delivery end of the transmission mechanism 10, the second pneumatic mechanism 30 blows and cleans the other surface (i.e., the upper surface) of the plate 90. In this way, it is avoided that if the first pneumatic mechanism 20 and the second pneumatic mechanism 30 are arranged too close in the height direction, the wind blown by the two will converge in the air to form a mutual interference phenomenon that disturbs the airflow, thereby affecting the cleaning strength and blowing efficiency of the plate 90.

[0032] Please refer to Figure 3 The transmission mechanism 10 includes a fixed bracket 11 and a plurality of roller groups 12, and the plurality of roller groups 12 are arranged on the fixed bracket 11. Specifically, in one embodiment, each roller group 12 includes a plurality of rollers of equal number and a rotating shaft, and the plurality of rollers are sleeved on the rotating shaft. A plurality of rotating shaft positioning parts are arranged on the fixed bracket 11, and the two ends of the rotating shaft are arranged on the rotating shaft positioning parts, so that the plurality of roller groups 12 are arranged on the fixed bracket 11 in sequence.

[0033] Optionally, the fixed bracket 11 includes a connecting rod 112 and a base 113, and both ends of the connecting rod 112 are connected to the base 113 so that the extending direction of the connecting rod 112 is parallel to the moving direction of the plate 90, and a plurality of roller groups 12 are arranged on the connecting rod 112 at intervals along the extending direction of the connecting rod 112. Specifically, in one embodiment, the number of the base 113 and the connecting rod 112 is two, and the two bases 113 are arranged at intervals, and the extending direction is parallel to the width direction of the plate 90. Both ends of the connecting rod 112 are connected to the two bases 113 respectively, so that the extending direction of the connecting rod 112 is parallel to the length direction of the plate 90, that is, parallel to the moving direction of the plate 90, and a plurality of roller groups 12 are arranged on the connecting rod 112 at intervals along the extending direction of the connecting rod 112 to form a conveying track for placing and conveying the plate 90.

[0034] Optionally, the first pneumatic mechanism 20 is arranged at one side of the transmission mechanism 10 with the connecting rod 112 spaced apart, and the second pneumatic mechanism 30 is arranged at the other side of the transmission mechanism 10 with the roller group 12 spaced apart. Specifically, in one embodiment, the first pneumatic mechanism 20 is arranged below the transmission mechanism 10 with the connecting rod 112 spaced apart, so that the wind blown out by the first pneumatic mechanism 20 can pass through the gap between the two roller groups 12, and then blow to the lower surface of the plate 90 located above the roller group 12. The second pneumatic mechanism 30 is arranged above the transmission mechanism 10 with the roller group 12 spaced apart, so that the wind blown out by the second pneumatic mechanism 30 can directly blow to the upper surface of the plate 90 located above the roller group 12. Among them, since the number of the first pneumatic mechanism 20 and the second pneumatic mechanism 30 is not limited, the user can set one or more first pneumatic mechanisms 20 and second pneumatic mechanisms 30 according to actual needs to improve cleaning efficiency.

[0035] Optionally, the first pneumatic mechanism 20 is disposed on the base 113. Specifically, in this embodiment, the extension direction of the first pneumatic mechanism 20 is parallel to the width direction of the plate 90 and is fixed on the base 113, thereby improving the space utilization rate of the workshop site.

The two ends of the first air intake duct 23 are respectively connected to the first box 21 and the first fan (not marked in the figure). The first fan (not marked in the figure) is used to send gas into the first box 21 through the first air intake duct 23. The first box 21 is provided with a first air outlet 212 for discharging the gas. The air outlet direction of the first air outlet 212 is toward the moving direction of the plate 90. Specifically, in the illustrated structure, the first box 21 is a long strip structure. The extension direction of the first box 21 is parallel to the width direction of the plate 90, so that the first box 21 is arranged on the base 113 along the width direction of the plate 90. The first air inlet duct 23 is connected to the side of the first box 21, and is used to input high-pressure gas into the first box 21 under the operation of the first fan (not shown in the figure). A first air outlet 212 is provided on the first box 21, and the first air outlet 212 is used to discharge the gas in the first box 21 and blow it in the moving direction of the plate 90. In one embodiment, the first box 21 is fixed to the base 113 by bolts and nuts.

[0037] Please refer to Figure 2 and Figure 5 , the second pneumatic mechanism 30 includes a pneumatic unit 31 and a support column 32, the support column 32 is arranged on the outside of the connecting rod 112, and the pneumatic unit 31 is arranged on the support column 32. Specifically, in one embodiment, the number of the support columns 32 is two, and the height of the support column 32 is greater than the height of the base 113. The two support columns 32 are respectively arranged on the outside of the two connecting rods 112, and the two ends of the pneumatic unit 31 are respectively arranged on the two support columns 32 so that the extension direction of the pneumatic unit 31 is parallel to the width direction of the plate 90. In the illustrated structure, the pneumatic unit 31 and the two support columns 32 form an arch-shaped structure surrounding the transmission mechanism 10, which not only ensures the cleaning strength and cleaning efficiency of the surface of the plate 90, but also further improves the space utilization rate of the workshop site.

[0038] Optionally, the pneumatic unit 31 includes a second box 312, a second air intake duct 33 and a second fan (not marked in the figure), the second box 312 is arranged on the support column 32 along the width direction of the plate 90, the two ends of the second air intake duct 33 are respectively connected to the second box 312 and the second fan (not marked in the figure), the second fan (not marked in the figure) is used to send gas into the second box 312 through the second air intake duct 33, the second box 312 is provided with a second air outlet 313 for discharging gas, and the air outlet direction of the second air outlet 313 is toward the moving direction of the plate 90. Specifically, in the illustrated structure, the second box 312 is a long strip structure, the second box 312 is arranged on the support column 32, and the extension direction of the second box 312 is parallel to the width direction of the plate 90. The second air intake duct 33 is connected to the side of the second box 312, and is used to input gas into the second box 312 under the operation of the second fan (not marked in the figure). The second box body 312 is provided with a second air outlet 313 for discharging the gas in the second box body 312 and blowing it toward the moving direction of the plate 90. In one embodiment, the second box body 312 is fixed to the support column 32 by bolts and nuts.

[0039] Please refer to Figure 4 and Figure 5 The first air outlet 212 and the second air outlet 313 are in the shape of long strips parallel to the width direction of the plate 90. Specifically, in this embodiment, the narrow strip-shaped air outlet has the following advantages compared to the wide-mouthed air outlet: first, under the same ventilation condition, the air volume of the long strip-shaped air outlet is more concentrated and the cleaning efficiency is higher; second, the manufacturing process of the long strip-shaped air outlet is simpler and the cost is lower.

[0040] The specific implementation method of this application is:

[0041] When the front end of the sheet 90 after the cutting process enters the conveying mechanism 10, the first pneumatic mechanism 20 inputs high-pressure air into the first box 21 through the first air intake structure 23, and then the gas in the first box 21 is discharged through the first air outlet 212, forming huge air kinetic energy to blow off the residual sawdust or debris on the lower surface of the sheet 90. The sheet 90 continues to move forward under the transmission of the conveying mechanism 10 until the front end of the sheet 90 approaches the second pneumatic mechanism 30, and the second pneumatic mechanism 30 inputs high-pressure air into the second box 312 through the second air intake structure 33, and then the gas in the second box 312 is discharged through the second air outlet 313 to blow off the residual sawdust or debris on the upper surface of the sheet 90. In this way, after the cut sheet 90 is removed from the conveying mechanism 10, the upper and lower surfaces are cleaned more thoroughly, which is convenient for the staff on the workshop site to perform the next process on the sheet 90, such as packaging.

[0042] The present application arranges a first pneumatic mechanism and a second pneumatic mechanism on both sides of the transmission mechanism in the height direction so as to blow air toward two opposite surfaces of the plate on the transmission mechanism, thereby effectively cleaning sawdust or debris left on the surface of the PMMA plate after cutting. The application has the characteristics of simple structure, small space occupation and strong operating efficiency, and has high application value.
