The radial dimension of the protective cover 310 is less than or equal to the radial dimension of the pulley 120. The locking structure 320 is configured to seal and fix the protective cover 310 to the transmission shaft 110 and the pulley 120.

[0047] The carrier conveying device is implemented by sleeve-mounting the pulley 120 on the transmission shaft 110 and clamping the tension sleeve 140 between the pulley 120 and the transmission shaft 110, so that the pulley 120 is meshed with the transmission belt 130. The rotation of the transmission shaft 110 can drive the pulley 120 to rotate, and then drive the transmission belt 130 meshed with the pulley 120 to move, thereby achieving the conveying effect of the carrier glass overlapped on the transmission belt 130; by arranging the spray assembly 200 to spray water on the end face of the transmission belt 130 away from the carrier glass, the circular movement of the transmission belt 130 can transfer the water on the transmission belt 130 to the carrier glass, thereby achieving the wetting of the carrier glass; by sleeve-mounting the protective cover 310 It is arranged on the outer periphery of the transmission shaft 110, and the opening of the protective cover 310 is pressed against the end face of the pulley 120 along the axial direction of the transmission shaft 110, and the opening is covered on the outer periphery of the tensioning sleeve 140, to ensure that the radial dimension of the protective cover 310 is less than or equal to the radial dimension of the pulley 120, and the locking structure 320 is used to seal and fix the protective cover 310 to the transmission shaft 110 and the pulley 120, so as to effectively prevent the water sprayed by the spray assembly 200 from flowing along the gap between the pulley 120, the tensioning sleeve 140 and the transmission shaft 110, and solve the rust problem caused by the accumulation of water in the gap between the pulley 120, the tensioning sleeve 140 and the transmission shaft 110, so as to ensure the normal operation of the conveying assembly 100 and thus ensure the production efficiency.

[0048] It should be noted that the specific structure and fixing principle of the tension sleeve 140 belong to the prior art and will not be described in detail here.

[0049] Specifically, the protective cover 310 and the locking structure 320 are both made of waterproof materials. By making the protective cover 310 and the locking structure 320 both of them of waterproof materials, it is possible to prevent the accumulated water remaining on the protective cover 310 and the locking structure 320 from rusting on the protective cover 310 and the locking structure 320. It should be noted that, in the present embodiment, the protective cover 310 and the locking structure 320 are both made of SUS301, SUS304 or SUS316.

By filling the gap between the protective cover 310 and the pulley 120 and the gap between the protective cover 310 and the transmission shaft 110 with sealant, and sealing the gap with sealant, water from the spray assembly 200 can be further prevented from flowing into the gap. It should be noted that in other embodiments, sealant can be filled only in the gap between the protective cover 310 and the pulley 120, or only in the gap between the protective cover 310 and the transmission shaft 110, which is not specifically limited in this embodiment.

[0051] In addition, an elastic structure may be provided in the gap between the protective cover 310 and the pulley 120, and an elastic structure may be provided in the gap between the protective cover 310 and the transmission shaft 110.

[0053] In an optional embodiment, a plurality of pulleys 120 are provided in the conveying assembly 100, and the plurality of pulleys 120 are arranged at intervals along the axial direction of the transmission shaft 110, and each pulley 120 is arranged corresponding to a tension sleeve 140 and a sealing assembly 300, and each pulley 120 is meshed with the transmission belt 130. By fixing a plurality of pulleys 120 at intervals on the transmission shaft 110 using the tension sleeve 140, each pulley 120 is meshed with the transmission belt 130, and the driving effect of the transmission belt 130 can be improved. By making each pulley 120 corresponding to a sealing assembly 300, each pulley 120 and the corresponding tension sleeve 140 and the transmission shaft 110 can be waterproofly sealed. It should be noted that in this embodiment, four pulleys 120 are arranged at intervals along the axis of the transmission shaft 110, and each pulley 120 is arranged corresponding to a sealing assembly 300 and a tension sleeve 140. In other embodiments, the specific number of the pulleys 120 may be adjusted according to actual needs, and it is only necessary to ensure that each pulley 120 is provided with a corresponding sealing assembly 300 and a tension sleeve 140, which is not specifically limited in this embodiment.

In other embodiments, the specific number of the spray branch pipes 211 can also be adjusted according to actual needs, and this embodiment does not specifically limit it.

The locking structure 320 includes a clamp, a penetration rod 321 and a fixing member 322, wherein the clamp is sleeved on the outer periphery of the protective cover 310, the penetration rod 321 penetrates through the clamp, and both axial ends of the penetration rod 321 extend out of the clamp, and both axial ends of the penetration rod 321 are fixed with fixing members 322, and the fixing member 322 can clamp the protective cover 310 between the clamp and the transmission shaft 110. By sleeve-arranging the clamp on the outer periphery of the protective cover 310, using the fixed connection of the fixing member 322 and the penetration rod 321, the protective cover 310 can be clamped between the clamp and the transmission shaft 110 by shrinking the clamp, so as to ensure the sealing and fixing of the protective cover 310 and the transmission shaft 110. It should be noted that, in this embodiment, the penetration rod 321 is a threaded rod, and the fixing member 322 is a bolt. When the protective cover 310 and the transmission shaft 110 need to be fixed, the nuts at both ends of the threaded rod are moved toward each other along the threaded rod by screwing the nuts, and then the protective cover 310 is clamped between the clamp and the transmission shaft 110, so as to effectively fix the protective cover 310 and the transmission shaft 110. When the fixed protective cover 310 and the transmission shaft 110 need to be disassembled, the nuts are screwed in the opposite direction, so that the nuts at both ends of the threaded rod are moved away from each other along the threaded rod, so as to loosen the clamp, the protective cover 310 and the transmission shaft 110.

[0057] Specifically, before connecting and fixing the clamp, the protective cover 310 and the transmission shaft 110, it is necessary to move the protective cover 310 along the axial direction of the transmission shaft 110 until the opening of the protective cover 310 is in contact with the end face of the pulley 120 provided with the tensioning sleeve 140 to complete the sealing of the protective cover 310 and the pulley 120, and then fix the clamp, the protective cover 310 and the transmission shaft 110 by screwing the nut.

[0058] Embodiment 2

[0059] This embodiment provides a plate glass conveying device. The specific structure of the plate glass conveying device provided in this embodiment is basically the same as that of the first embodiment. The difference between the plate glass conveying device provided in this embodiment and the first embodiment is that the number of sealing assemblies 300 corresponding to each pulley 120 is different.

[0061] Embodiment 3

[0062] This embodiment provides a plate glass conveying device. The specific structure of the plate glass conveying device provided in this embodiment is basically the same as that of the second embodiment. The difference between the plate glass conveying device provided in this embodiment and the second embodiment is that the specific structure of the pulley 120 is different.

By providing the annular extension protrusion 121 on the end face of the pulley 120 along the axial direction of the transmission shaft 110, and accommodating the protective cover 310 in the annular extension protrusion 121, when the spray assembly 200 sprays water, the annular extension protrusion 121 can first block most of the water from being sprayed onto the protective cover 310, and only a small part of the water will be sprayed onto the protective cover 310, and under the action of the protective cover 310, it cannot continue to flow into the gap between the pulley 120, the tension sleeve 140 and the transmission shaft 110, further solving the rust problem caused by water accumulation in the gap between the pulley 120, the tension sleeve 140 and the transmission shaft 110.
