[0047] Specifically, the driven wheel 02 is disposed on the support shaft 12. In an application scenario, the driven wheel 02 drives the support shaft 12 to rotate. The support shaft 12 is disposed in contact with the material tray 06. The support shaft 12 drives the corresponding material tray 06 to rotate through friction.

[0048] The above-mentioned arrangement is simple in structure and is more convenient for the driven wheel 02 to drive the material tray 06 .

[0049] Optionally, the support assembly includes a plurality of support shafts 12, and the plurality of support shafts 12 are arranged one by one with the plurality of driven wheels 02, and the support shafts 12 are in contact with and connected to the material tray 06.

[0050] In one application scenario, the rotation direction of the material tray 06 can be changed by changing the rotation direction of the driven wheel 02 .

[0051] Optionally, a transmission rubber bag is provided on the support shaft 12, and the material tray 06 is provided in contact with the transmission rubber bag. The surface of the transmission rubber bag has anti-slip pitting, which can provide 2 to 3 times the traction force, thereby improving the driving performance and reducing energy consumption; the surface of the transmission rubber bag can reduce the relative sliding between the support shaft 12 and the material tray 06, and effectively reduce the damage caused by the material tray 06 and the support shaft 12 due to sliding friction; the transmission rubber bag can also effectively play a role in buffering and shock absorption, thereby improving the operating efficiency of the transmission system composed of the support shaft 12 and the corresponding material tray 06 and extending its service life.

[0052] Optionally, a plurality of support shafts 12 are coaxially arranged, and adjacent support shafts 12 are movably connected.

[0053] The movable connection can ensure that the rotational movements of the multiple support shafts 12 do not affect each other.

[0054] Optionally, each support shaft 12 may correspond to a plurality of material trays 06 , thereby enabling group control of the material trays 06 .

[0055] In other embodiments, the second driving member includes a magnetic member, which is mounted on the second base and coupled to the first base so that when the magnetic member is energized, the first base moves toward the driven wheel along the second direction through magnetic force, so that the driving wheel and the driven wheel are transmitted.

[0056] In one application scenario, the magnetic member is electrified, so that the first seat body moves along the second direction toward the driven wheel on the first guide rail under the action of magnetic force, thereby causing the driving wheel to be in transmission with the corresponding driven wheel.

[0057] The beneficial effect of the above arrangement is that the first seat body is driven to move along the second direction on the first guide rail by the magnetic member, which is convenient and fast and improves the control convenience.

[0058] Optionally, the magnetic member is an electromagnet, which can drive the first seat body to move along the second direction on the first guide rail through magnetic force after being energized, so that the driving wheel and the driven wheel are arranged in a transmission manner.

[0059] Specifically, the electromagnet is composed of a coil and an iron core. When current passes through the coil, the coil generates a magnetic field, magnetizing the iron core, thereby generating a magnetic force. The magnitude and direction of the magnetic force can be adjusted by controlling the magnitude and direction of the current. The first seat body is placed in the magnetic field of the electromagnet. When the electromagnet is energized, the magnetic field will generate a magnetic force on the first seat body, causing the first seat body to move. By controlling the magnitude and direction of the current of the electromagnet, the magnitude and direction of the magnetic force can be controlled, thereby controlling the first seat body to drive the driving wheel to move closer to the driven wheel or away from the driven wheel. Using an electromagnet to drive the movement of the first seat body has the advantages of fast response speed, high control accuracy, and good reliability.

[0060] Optionally, the second driving member further comprises an elastic member, one end of the elastic member abuts against the second seat body, and the other end of the elastic member abuts against the first seat body, so as to provide a reset force for the first seat body to deviate from the driven wheel.

[0061] In one application scenario, based on the above-mentioned magnetic member, the second driving member further includes an elastic member. When it is no longer necessary to drive the material tray to rotate, the magnetic member can be controlled to be powered off, and the first seat body moves along the second direction on the first guide rail away from the driven wheel under the action of the elastic member, thereby separating the driving wheel from the corresponding driven wheel to complete power isolation.

[0062] The beneficial effect of the above arrangement is that by adding an elastic part, when there is no need to drive the material tray to rotate, the power of the magnetic part can be directly controlled to be cut off to achieve the resetting of the first seat body and the power isolation of the driving wheel and the driven wheel. There is no need for other complex controls (such as changing the magnetic poles of the magnetic part). The operation is simple and the structure is simple, which can reduce the difficulty and cost of production and assembly.

[0063] Optionally, the elastic member can be a spring, which generally has high reliability and can provide stable performance for a long time. The spring can be easily integrated with various devices and conveniently installed in various devices without the need for special tools or skills and at a low cost, thus saving costs.

[0064] Optionally, the first transmission assembly 04 further includes a worm 42 and a worm wheel 43. The worm 42 is disposed on the first seat body 55 and is in transmission connection with the first driving member 03. The worm wheel 43 is disposed on the first seat body 55 and is in transmission connection with the driving wheel 41 and the worm 42 respectively.

[0065] Specifically, the first driving member 03 and the driven wheel 02 and the material tray 06 are driven by the worm wheel 43, the worm 42 and the driving wheel 41. The worm 42 is arranged on the first seat 55, and transmits the driving force of the first driving member 03 to the worm wheel 43, and then to the driving wheel 41.

[0066] In the above setting, the power transmission between the first drive member 03 and the drive wheel 41 is realized by the worm gear 43 and the worm 42, which can realize the steering output of the driving force. Therefore, the position of the first drive member 03 can be adjusted based on product requirements, thereby improving the aesthetics and ease of use of the product.

[0067] Optionally, the worm wheel 43 and the driving wheel 41 can be arranged on the same rotating shaft. Specifically, the first driving member 03 drives the worm 42 to rotate, thereby driving the worm wheel 43 to rotate, and the worm wheel 43 drives the rotating shaft to rotate, thereby driving the driving wheel 41.

[0068] In other embodiments, the first driving member may be designed to directly drive the driving wheel without transmitting through a worm gear or a worm, which can further reduce the number of parts and improve assembly convenience.

[0069] Optionally, the first driving member 03 is arranged on the first seat body 55, and the worm 42 is arranged on the first driving member 03. This arrangement can improve the structural stability of the first driving member 03 and the worm 42, and further improve the transmission stability.

[0070] Optionally, the third driving member 53 is disposed at one end of the second guide rail 52 and is transmission-connected to the second base body 51 via a driving rod.

[0071] The third driving member 53 is disposed at one end of the second guide rail 52 . The third driving member 53 is transmission-connected to the second base body 51 via a driving rod, and drives the second base body 51 to move along the second guide rail 52 in the second direction X.
