In addition, a plurality of supporting wheels all distribute around the circumference of barrel 210, and a plurality of supporting wheels are when fixing on base 110, are along the circumferencial direction distribution setting of barrel 210 to when barrel 210 installs on base 110, each supporting wheel all with barrel 210 butt, thereby can distribute the gravity of barrel 210 on a plurality of supporting wheels, each supporting wheel all forms the support to barrel 210, further supports the steadiness that the wheel supported to barrel 210.

In some embodiments, the support wheel is a cam bearing, the cam shaft of the cam bearing is fixed to the base 110, and the cylinder 210 abuts against the cam bearing. The cam bearing is used as an auxiliary support, so that the cylinder 210 and the base 110 can roll relatively, and the friction force generated when the cylinder 210 rotates is reduced.

In order to prevent the roller 200 from rotating when the rack assembly is maintained as a whole, as shown in fig. 13, the rack assembly provided by the present disclosure is provided with a limiting structure, the limiting structure is disposed between the base 110 and the roller 200, and the limiting structure is used for preventing the roller 200 from rotating relative to the base 110. The drum 200 can be prevented from rotating by the limit structure, thereby facilitating maintenance of the rack assembly and other components on the drum 200.

In some embodiments, the limiting structure may be disposed between the supporting frame 120 and the driving disc 220, so as to limit the driving disc 220 to rotate, so as to stop the rotation of the cylinder 210; or between the cylinder 210 and the base 110 to directly limit the rotation of the cylinder 210, so that the driving disc 220 stops rotating, thereby facilitating the maintenance of the equipment; compare and set up limit structure between support frame 120 and driving-disc 220, set up limit structure between base 110 and barrel 210, be favorable to hiding limit structure more, be favorable to holistic pleasing to the eye.

As shown in fig. 13, the limiting structure provided by the present disclosure includes a plug (not shown in the figure), a first limiting hole 211 opened on the cylinder 210, and a second limiting hole 161 arranged on the base 110, wherein the plug is used for being inserted into the first limiting hole 211 and the second limiting hole 161. That is, when the drum 200 rotates to the position where the first and second position-limiting holes 211 and 161 are located, the two ends of the inserted pin are inserted into the first and second position-limiting holes 211 and 161, respectively, and the base 110 is fixed, so that the inserted pin, one end of which is inserted into the second position-limiting hole 161, is also fixed, and when the other end of the inserted pin is inserted into the first position-limiting hole 211 on the drum 200, the drum 200 can be limited, and the drum 200 cannot rotate relative to the base 110.

In some embodiments, the axes of the first limiting hole 211 and the second limiting hole 161 may form an included angle, and at this time, the plug pin needs to be composed of two parts forming an included angle with each other, so that when the first limiting hole 211 and the second limiting hole 161 are located at corresponding positions, two ends of the plug pin can be respectively inserted into the corresponding first limiting hole 211 and the second limiting hole 161, and further the rotation of the drum 200 relative to the base 110 can be prevented.

Specifically, the axis of the first position-limiting hole 211 and the axis of the second position-limiting hole 161 form an included angle, that is, the axes of the first position-limiting hole 211 and the second position-limiting hole 161 cannot coincide, so that the plug pin needs to be composed of two parts, and when one part of the plug pin is inserted into the first position-limiting hole 211, the axis of the other part of the plug pin just coincides with the second position-limiting hole 161, so that the other part of the plug pin can be inserted into the second position-limiting hole 161, and the two ends of the plug pin are respectively inserted into the first position-limiting hole 211 and the second position-limiting hole 161, so as to limit the drum 200.

It should be noted that, the parts of the straight rod structure provided by the present disclosure need to adopt parts with strong rigidity, and flexible materials, that is, parts capable of bearing large force without bending or breaking, cannot be used.

In addition, the position of the first limiting hole 211 corresponding to the position of the second limiting hole 161 means that two ends of the plug pin can be inserted into the first limiting hole 211 and the second limiting hole 161 at the same time, so that the plug pin can limit the barrel 210 from rotating relative to the base 110. For example, in a scheme that the axes of the first and second limiting holes 211 and 161 are parallel to the axis of the drum 200, the corresponding positions of the first and second limiting holes 211 and 161 refer to positions where the axes of the first and second limiting holes 211 and 161 coincide, and at this time, the plug pins may be sequentially inserted into the first and second limiting holes 211 and 161.

In addition, the driving mechanism 300 is connected with the friction wheel through a long driving shaft, which affects transmission efficiency, and the friction wheel transmission has a large positioning error, which causes play along the axial direction of the drum 200 during supporting, which affects the rotation precision of the drum 200.
