Alternatively, the guide bracket 143 may be fixedly connected to the fine adjustment bracket 140, or may be detachably connected thereto. The fixed connection can adopt welding, riveting or other connection modes, and the detachable connection can adopt threaded connection, clamping connection or other connection modes.

In some embodiments, to facilitate the connection of the drive cord 12 to the adjustment lever 141, as shown in fig. 10, the fine adjustment assembly 14 further includes a second connector 1423, and the second connector 1423 connects the adjustment lever 141 and the second end 121 of the drive cord 12.

Alternatively, the second connecting member 1423 may be detachably connected to the adjusting rod 141 and the driving belt 12, and the detachable connection may be a threaded connection, a snap connection, or other connection.

On this basis, in order to relatively fix the driving rope 12 on the adjusting lever 141, the fine adjustment assembly 14 further includes a third fastener 1424, the third fastener 1424 is located on one side of the adjusting lever 141 in the radial direction, the second end 121 of the driving rope 12 is located between the third fastener 1424 and the adjusting lever 141, the second connector 1423 sequentially passes through the third fastener 1424 and the second end 121 of the driving rope 12 and is connected to the adjusting lever 141, and the second connector 1423 relatively fixes the driving rope 12 on the adjusting lever 141 through the third fastener 1424. Since the transmission string 12 is relatively fixed to the adjustment lever 141, the transmission string 12 can be rotated by the rotation of the adjustment lever 141, and the transmission string 12 can be wound around the adjustment lever 141 or can be converted from a wound state to an extended state by the normal rotation or reverse rotation of the adjustment lever 141.

In some embodiments, as shown in fig. 11, the drive assembly 10 includes: a drive frame 100, a drive 101, a drive shaft 102 and a plurality of drive pulleys 103. The driver 101 is installed on the driving frame 100, the driving shaft 102 is rotatably connected with the driving frame 100, and a plurality of driving pulleys 103 in transmission connection with the driver 101 are installed on the driving shaft 102 and correspond to the plurality of transmission ropes 12 one by one.

It will be appreciated that the first end 120 of the drive belt 12 is connected to the drive pulley 103. The driving shaft 102 is driven by the driver 101 to rotate, the driving pulley 103 is mounted on the driving shaft 102, so that the driving pulley 103 can rotate along with the rotation of the driving shaft 102, and the first end 120 of the transmission rope belt 12 is connected with the driving pulley 103, so that the transmission rope belt 12 can be wound on the driving pulley 103 or changed from a winding state to an extending state under the condition that the driving shaft 102 is driven by the driver 101 to rotate forwards or backwards.

On this basis, as shown in fig. 12, the driving pulley 103 has a pulley groove 1030 and a mounting chamber 1031, the pulley groove 1030 is disposed around the mounting chamber 1031, the driving shaft 102 is located in the mounting chamber 1031, and the mounting chamber 1031 extends in the circumferential direction of the driving shaft 102 and is located between the pulley groove 1030 and the driving shaft 102. The opposite bottom wall surface of the pulley groove 1030 is provided with a mounting hole 10300, and the mounting hole 10300 is communicated with the pulley groove 1030 and the mounting cavity 1031, so that the first end 120 of the transmission rope 12 passes through the mounting hole 10300 and extends into the mounting cavity 1031. Therefore, an installation position can be provided for the third connecting member 1032, and one end of the third connecting member 1032 close to the pulley groove 1030 is prevented from being in direct contact with the transmission rope belt 12, so that the transmission rope belt 12 is prevented from being worn, and the service life of the transmission rope belt 12 is prolonged.

On the basis, the driving pulley 103 further has a third connecting member 1032, the bottom wall surface of the pulley groove 1030 is provided with a connecting hole 10301, the connecting hole 10301 is communicated with the pulley groove 1030 and the mounting chamber 1031, the third connecting member 1032 is fitted in the connecting hole 10301, and the third connecting member 1032 extends into the mounting chamber 1031 and connects the first end 120 of the driving rope belt 12 and the driving pulley 103. The transmission rope belt 12 is connected with the driving pulley 103 through the third connecting piece 1032, so that the connection between the transmission rope belt 12 and the driving pulley 103 is more convenient and firmer.

In some embodiments, as shown in fig. 13, the driving assembly 10 further includes a fourth fastener 1033, the fourth fastener 1033 is located in the mounting chamber 1031, the first end 120 of the driving cord 12 is located on a side of the fourth fastener 1033 facing away from the connecting hole 10301, and the third connecting member 1032 passes through the fourth fastener 1033 and the first end 120 of the driving cord 12 in sequence and is connected to the driving pulley 103. The fourth fastener 1033 fixes the driving belt 12 and the driving pulley 103 relatively by the third connector 1032.

The fourth fastener 1033 is a sheet-shaped structure, the fourth fastener 1033 directly contacts the first end 120 of the driving rope belt 12, the third connector 1032 connects the fourth fastener 1033 with the driving pulley 103, and the fourth fastener 1033 presses the first end 120 of the driving rope belt 12 against the driving pulley 103, so that the acting force between the first end 120 of the driving rope belt 12 and the third connector 1032 can be reduced, and the service life of the driving rope belt 12 can be prolonged.

In addition, the driving assembly 10 may apply a large force to the transmission belt 12 when it is stopped, which may cause the transmission belt 12 to shake and deform, thereby affecting the stability of the driving pulley 103 and the life of the transmission belt 12.

When the first end 120 of the drive cord 12 is in the limit position, i.e., when no drive cord 12 is wrapped around the pulley groove 1030. At the start-up and shut-down moments, the driving pulley 103 applies a large force to the first end 120 of the driving rope 12, causing the driving rope 12 to sway and deform. Since the fourth fastener 1033 fixes the driving rope 12, the shaking of the driving rope 12 can be reduced, thereby improving the stability of the driving pulley.

In addition, the force applied to the first end 120 of the drive belt 12 at the start and stop moment can be reduced by paying out a drive belt of an appropriate length in cooperation with the fine adjustment assembly 14, so as to reduce the deformation of the drive belt 12 and increase the service life of the drive belt 12.

Specifically, when the first end 120 of the transmission belt 12 is at the limit position, at the moment of starting and stopping, the transmission belt 12 is subjected to a large acting force, and at this time, the transmission belt 12 is in a stretched state, the first fastening member 1420 can be adjusted by adjusting the first fastening member 1422, and the adjustment lever 141 can be rotated by adjusting the second fastening member 1421, so that the transmission belt 12 in the fine adjustment assembly 14 moves toward the side away from the transport plate 13 along the up-down direction (i.e., the transmission belt 12 moves upward), so that the transmission belt 12 is relaxed from the stretched state, and the service life of the transmission belt 12 is prolonged.

The particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
