[0020] an arc-shaped plate used for closing the third opening;
[0021] a clamping plate arranged on an outer wall of the arc-shaped plate and used for abutting against an inner side of the horizontal plate.
[0022] Optionally, the arc-shaped inner plate and the arc-shaped outer plate are both optimal arc plates.
[0023] Optionally, the length of the arc-shaped cylinder structure ranges from 15 mm to 25 mm.
[0024] A sand covering system comprises a sand blasting port and a suction machine used for supplying sand to the sand blasting port, and further comprises any one of the composite bar sand covering back-blowing devices, and the sand blasting port is arranged at the third opening of the composite bar sand covering back-blowing device.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0040] The core of the present application is to provide a composite bar sanding reverse blowing device, which can improve the uniformity of composite bar sanding. Another core of the present application is to provide a sanding system comprising the above-mentioned composite bar sanding reverse blowing device, which has good uniformity of composite bar sanding.
[0041] Please refer to Figures 1 to 6 , Figure 1 for the structural schematic diagram of the composite bar sanding reverse blowing device provided by the embodiments of the present application; Figure 2 for Figure 1 the front view; Figure 3 for Figure 1 the left view; Figure 4 for Figure 1 the top view after rotating 180 degrees; Figure 5 for the connection structure schematic diagram of the third opening of the arc-shaped cylinder structure and the sand blasting port in the embodiments of the present application; Figure 6 for the structural schematic diagram of the sanding system provided by the embodiments of the present application.
[0042] The present application provides a composite bar sanding reverse blowing device 100, comprising an arc-shaped inner plate 1, an arc-shaped outer plate 2, two cover plates 4 and a connecting nozzle 5. The arc-shaped inner plate 1 is provided with a plurality of blowing holes 11, and is used for passing through the composite bar 9. The arc-shaped inner plate 1 is arranged inside the arc-shaped outer plate 2, and has a predetermined spacing therebetween. The two edge portions of the first opening of the arc-shaped inner plate 1 are connected with the two edge portions of the second opening of the arc-shaped outer plate 2 one by one, so as to form an arc-shaped cylinder structure 3 with a third opening. The third opening is used for arranging a sand blasting port 8 of a sanding system. The two cover plates 4 are arranged at the two ends of the arc-shaped cylinder structure 3, so as to close the arc-shaped cylinder structure 3. The connecting nozzle 5 is arranged on the cover plate 4 and communicates with the inside of the arc-shaped cylinder structure 3. The connecting nozzle 5 is used for connecting with a compressed air source.
[0043] In use, the sand injection port 8 of the sand coating system is arranged at the third opening of the arc-shaped cylinder structure 3, and the composite rib 9 passes through the inner hole of the arc-shaped inner plate 1. The sand (such as quartz sand) is sprayed through the sand injection port 8 to align the composite rib 9. Part of the sand falls on the side of the composite rib 9 facing the sand injection port 8, and part of the sand falls on the inner wall of the arc-shaped inner plate 1. At this time, the compressed air provided by the compressed air source is introduced into the inside of the arc-shaped cylinder structure 3 through the connecting nozzle 5, and then blown out from the air blowing hole 11 of the arc-shaped inner plate 1 to blow the sand falling on the inner wall of the arc-shaped inner plate 1 to the part of the composite rib 9 not directly facing the sand injection port 8. Since the main body structure of the back blowing device is arc-shaped, the compressed air blown out from the air blowing hole 11 of the arc-shaped inner plate 1 can make the sand spray to the composite rib 9 in multiple directions, so that the sand coating of the composite rib 9 is more uniform. Therefore, compared with the back blowing device in the prior art which can only coat the bottom of the composite rib 9, the composite rib sand coating back blowing device 100 can coat the composite rib 9 in multiple directions, expand the sand coating coverage, increase the sand coating area, and improve the uniformity of the sand coating of the composite rib 9.
[0044] In order to facilitate the connection of the composite rib sand coating back blowing device 100 and the sand injection port 8 of the sand coating system, on the basis of the above embodiment, a connecting device for connecting the sand injection port 8 of the sand coating system is arranged at the third opening of the arc-shaped cylinder structure 3. That is, in the present embodiment, the connecting device is arranged at the third opening of the arc-shaped cylinder structure 3 to facilitate the connection of the third opening of the arc-shaped cylinder structure 3 and the sand injection port 8 of the sand coating system.
[0045] It should be noted that the specific structure of the connecting device is not limited in the present embodiment, as long as the connecting device can be reasonably designed to realize the connection of the third opening of the arc-shaped cylinder structure 3 and the sand injection port 8 of the sand coating system.
[0046] As a preferred solution, on the basis of the above embodiment, the connecting device includes two oppositely arranged clamping assemblies 6, and the two clamping assemblies 6 are respectively connected to the two edge portions of the third opening of the arc-shaped cylinder structure 3. That is, in the present embodiment, the sand injection port 8 of the sand coating system is clamped and fixed with the clamping assembly 6, which is convenient for assembly.
[0047] In one embodiment, the clamping assembly 6 includes a vertical plate 61 connected to the edge portion of the third opening and a horizontal plate 62 vertically connected to the side of the vertical plate 61 away from the third opening. That is, the vertical plate 61 and the horizontal plate 62 of one clamping assembly 6 form a reversed L-shaped clamping port, and the two clamping assemblies 6 form two clamping ports, and the two clamping ports are oppositely arranged to facilitate clamping the sand injection port 8 of the sand coating system, which is simple in structure and convenient to process.
[0048] In one embodiment, the mounting plate 7 connected with the sand blasting port 8 is further included, the mounting plate 7 includes an arc-shaped plate 71 and a clamping plate 72, the clamping plate 72 is connected with the outer wall of the arc-shaped plate 71, the arc-shaped plate 71 is used for closing the third opening of the arc-shaped cylinder structure 3; the clamping plate 72 is used for abutting and fitting with the inner side of the horizontal plate 62.
[0049] During installation, the mounting plate 7 is inserted into the two clamping ports, the arc-shaped plate 71 is arranged at the third opening of the arc-shaped cylinder structure 3, and the clamping plate 72 is abutting and fitting with the inner side of the horizontal plate 62, so as to realize the connection between the mounting plate 7 and the clamping port, and the mounting plate 7 is clamped and fixed with the clamping port, and the connection between the sanding port 8 of the sanding system and the third opening of the arc-shaped cylinder structure 3 is realized.
[0050] In addition, in order to expand the sanding range, in one embodiment, the arc-shaped inner plate 1 and the arc-shaped outer plate 2 are both optimal arc plates. It can be understood that the arc length and the central angle of the optimal arc plate are larger, which can increase the orientation of the composite rib 9 for sanding, expand the sanding coverage range, increase the sanding area, and further improve the uniformity of the sanding of the composite rib 9.
[0051] In addition, in one embodiment, the length of the arc-shaped cylinder structure 3 ranges from 15 to 25 mm. Preferably, the length of the arc-shaped cylinder structure 3 is 20 mm.
[0052] It should be noted that when the length of the arc-shaped cylinder structure 3 is too long, since the connecting nozzle 5 is usually arranged on one cover plate 4, the compressed air entering the inside of the arc-shaped cylinder structure 3 from the connecting nozzle 5 flows from the cover plate 4 close to the connecting nozzle 5 to the cover plate 4 far from the connecting nozzle 5, and in this process, the compressed air is blown out from the blowing hole 11 of the arc-shaped inner plate 1, so that the flow of compressed air at the two cover plates 4 is not equal, the flow of compressed air at the cover plate 4 close to the connecting nozzle 5 is large, and the flow of compressed air at the cover plate 4 far from the connecting nozzle 5 is insufficient, so that when the sand sprayed from the sanding port 8 falls on the surface of the composite rib 9 immersed in resin and then falls on the inner wall of the arc-shaped inner plate 1, it is easy to adhere to the blowing hole 11 of the arc-shaped inner plate 1, and with the increase of the use time, the sand is easy to accumulate at the end of the arc-shaped inner plate 1 far from the connecting nozzle 5, block the air flow, and cause the sanding of the composite rib 9 to be uneven. Therefore, the length of the arc-shaped cylinder structure 3 is designed in the range of 15 to 25 mm in the embodiment, so that the length of the arc-shaped cylinder structure 3 is shorter, so as to minimize the difference in the flow of compressed air at the two cover plates 4, solve the problem that one end of the arc-shaped inner plate 1 is easy to block, and improve the sanding uniformity. Moreover, the structure of the composite rib sanding back-blowing device 100 provided by the embodiment is small and convenient to install, and can be applied to the sanding system which is complex and not convenient to modify.
[0053] In addition to the composite sand-coated reverse blowing device 100 described above, the present application also provides a sand-coating system comprising the composite sand-coated reverse blowing device 100 disclosed in the above embodiments, which further comprises a sand spraying port 8 and a sand suction machine for supplying sand to the sand spraying port 8, and the sand spraying port 8 is arranged at the third opening. The structures of other parts of the sand-coating system can refer to the prior art, which will not be described here.
[0054] In operation, the sand suction machine supplies sand to the sand spraying port 8 through the sand suction effect, so that the sand is sprayed out of the sand spraying port 8, and then sprayed on the side of the composite bar 9 opposite to the sand spraying port 8, and falls on the inner wall of the arc-shaped inner plate 1 of the composite sand-coated reverse blowing device 100, and is blown on the side of the composite bar 9 not opposite to the sand spraying port 8 under the action of the air blowing hole 11 of the arc-shaped inner plate 1, so that the composite bar 9 is uniformly coated with sand.
[0055] On the basis of the above embodiments, the sand-coating system further comprises an intelligent traction control device for controlling the traction speed of the composite bar 9 passing through the arc-shaped inner plate 1 of the composite sand-coated reverse blowing device 100, and the sand suction machine is connected to the intelligent traction control device, so that the intelligent traction control device adjusts the flow of sand supplied by the sand suction machine according to the traction speed of the composite bar 9. That is, the sand flow supplied by the sand suction machine can be adjusted according to the traction speed of the composite bar 9 in this embodiment, so that the sand coating density on the surface of the composite bar 9 can be adjusted, and the appearance and uniformity of the product can be ensured.
[0056] Further, in one embodiment, the sand-coating system further comprises a sand spraying box 200, and the composite sand-coated reverse blowing device 100 is arranged in the sand spraying box 200, and the sand spraying box 200 is provided with an open recycling device 300, and the recycling device 300 is located at the bottom of the composite sand-coated reverse blowing device 100. That is, the sand falling outside the composite sand-coated reverse blowing device 100 is recycled by adding the recycling device 300 in this embodiment, so that the waste of sand is prevented.
[0057] It should be further noted that the relative terms such as first and second in the present specification are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations.
[0058] The various embodiments in the present specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same or similar parts between various embodiments can be referred to each other.
