In some embodiments, as shown in fig. 1-8, the belt 13 is an endless belt 13, and the driving pulley 11 and the driven pulley 12 are disposed inside the endless belt 13. The driving pulley 11 is connected with a pulley driving device 14, and the pulley driving device 14 drives the driving pulley 11 to rotate, so that the driving belt 13 is driven to move along the winding direction.
Referring to fig. 1-4, in some embodiments, the transport mechanism includes a set of track lines 1. The width of the driving belt 13 is matched with the size of the articles to be conveyed, the articles are placed on the driving belt 13, and the driving belt 13 can drive the articles to move.
Referring to fig. 5-7, in some embodiments, the conveyor mechanism includes two sets of track lines 1a, 1b, the two sets of track lines 1a, 1b being spaced apart, and the belts 13 of the two sets of track lines 1a, 1b being disposed in parallel and moving in synchrony. When an article with larger width needs to be conveyed, two ends of the article can be respectively placed on the driving belts 13 of the two groups of track lines 1a and 1b, so that the article spans between the two groups of track lines 1a and 1b, and the middle part of the article is suspended, thereby reducing the use area of the driving belts 13.

The dust removing driving device 54 is connected with the dust removing brush 52, and the dust removing driving component is used for driving the dust removing brush 52 to move so that the dust removing brush 52 can be close to or far away from the transmission belt 13 as required. In one embodiment, the dust removal drive device 54 periodically moves the dust removal brush 52 to perform a plurality of cleaning cycles; in one cleaning cycle, the dust removing driving device 54 drives the dust removing brush 52 to approach the driving belt 13 to clean the driving belt 13, and after the dust removing brush 52 contacts the driving belt 13 for a predetermined time, the dust removing driving device 54 drives the dust removing brush 52 to be away from the driving belt 13. Thereby, the abrasion of the belt 13 due to the contact of the dust brush 52 with the belt 13 can be reduced while keeping the surface of the belt 13 clean.
The box body 51 is provided with a through hole 511, the driving belt 13 is arranged through the through hole 511 in a penetrating mode, when the driving belt 13 continuously moves, all parts on the driving belt 13 sequentially pass through the dust collection assembly 50, and when the driving belt 13 enters the box body 51, the dust collection brush 52 can clean a section of the driving belt 13 entering the box body 51. Alternatively, the dust brush 52 may be disposed under the belt 13, and the dust box 53 is disposed under the dust brush 52, and the swept dust falls into the dust box 53 by gravity when the dust brush 52 contacts the surface of the belt 13.

Referring to fig. 18, the tension adjusting module of the control circuit 30 is further electrically connected to the detecting assembly 23, and the control circuit 30 receives a signal sent by the detecting assembly 23 and capable of indicating the position of at least one movable tension assembly 22, 22a, 22b, and controls the wedge driving device 212 to operate according to the signal of the detecting assembly 23, thereby detecting and automatically adjusting the tension of the driving belt 13.
The detection assembly 23 may include any kind of device or element capable of detecting the position of one or more components of the movable tensioning assembly 22, 22a, 22b, and may include, for example, a hall sensor, a photoelectric sensor, a proximity switch, a travel switch, or other sensor. In some embodiments, referring to fig. 12-15, the detection assembly 23 includes one or more shielded photosensors and a sensing piece 233, the sensing piece 233 is connected to the driving arm 221 or 221b, and when the driving arm 221 or 221b moves to a predetermined position, the sensing piece 233 blocks an optical path of the photosensors, and the photosensors are triggered to output a switching control signal.
Further, in some embodiments, referring to fig. 12-15, the detection assembly 23 includes a first sensor 231 and a second sensor 232, the first sensor 231 is spaced apart from the second sensor 232, and a line between the first sensor 231 and the second sensor 232 is substantially parallel to the second straight line L2. Optionally, the detecting assembly 23 may further include a stopper 234, and the stopper 234 may be provided with the first sensor 231 and the second sensor 232 mounted on the stopper 234 in parallel to the second straight line L2, thereby facilitating the assurance of the positions of the first sensor 231 and the second sensor 232 in height.
The positions of the first sensor 231 and the second sensor 232 are set according to the positions of the movable tensioning assemblies 22, 22a, 22b in different working states, so that the sensing piece 233 triggers the first sensor 231 when the transmission arms 221, 221a and/or 221b are located at the first position; when the actuator arms 221, 221a, and/or 221b are in the second position, the sensing tab 233 triggers the second sensor 232. When the belt 13 is installed, the tension driving assembly 21 can be controlled by the control circuit to drive the movable tension assemblies 22, 22a and 22b to move, so that the belt 13 maintains proper tension, the positions of the driving arms 221, 221a and/or 221b are marked as first positions, and then the first sensor 231 is installed, so that the sensing piece 233 triggers the first sensor 231. The second sensor 232 is fixed according to the stretch-proofing property of the belt 13, so that when the second sensor 232 is triggered by the sensor piece 233 moving the driving arms 221, 221a and/or 221b, the belt 13 breaks after exceeding the limit stretch length, and the position of the driving arms 221, 221a and/or 221b is recorded as the second position, and the second sensor 232 is spaced from the first sensor 231 by a certain distance. That is, when the drive arms 221, 221a and/or 221b are in the first position, the drive belt 13 is tensioned; as the drive arms 221, 221a, and/or 221b move from the first position to the second position, a decrease in the tension of the drive belt 13 is indicated; when the drive arms 221, 221a and/or 221b are moved to the second position, it is indicated that the drive belt 13 is broken.
When the belt 13 is loosened after the belt 13 is mounted, the driving arms 221, 221a and/or 221b gradually move from the first position to the direction approaching the second position, so that the sensing piece 233 moves away from the first sensor 231 and cannot trigger the first sensor 231. When the control circuit 30 does not receive the switching control signal transmitted by the first sensor 231 and does not receive the signal transmitted by the first sensor 231, it indicates that the belt 13 has come loose; at this time, the movable tensioning assemblies 22, 22a and 22b can be continuously pushed by the tensioning driving assembly 21 to move so as to tension the driving belt 13, and meanwhile, the position of the first sensor 231 can be adjusted again, so that the first sensor 231 is triggered by the sensing piece 233, and the tensioning state of the driving belt 13 can be continuously monitored.
When the belt 13 breaks, the belt 13 moves from the first position to the second position, so that the sensing piece 233 triggers the second sensor 232. When the control circuit 30 receives the signal sent by the second sensor 232, it indicates that the belt 13 has broken, and can send a notification to the staff accordingly, so that the staff can replace the belt 13 in time, and the influence on the article conveying work is reduced.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, and various modifications and variations may be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
