The outer layer of the cylinder is directly covered by a stainless steel thin plate (please refer to the shell 250 for understanding), fixed by a support plate, and directly insulated by air by utilizing the stainless steel thin plate and the hollow part of the cylinder. Only the top of the shoveling plate 213 in the cylinder body is provided with a joint gap, so that smoke dust and cleaning water are not easy to enter. And the cylinder body is made of only stainless steel and silicon rubber, so that the cylinder body is dustproof, waterproof and fireproof, and meets the requirements of food grade.

As shown in fig. 1, the present embodiment also provides a cartridge drive mechanism 100. The cartridge drive mechanism 100 includes a cartridge mounting structure 110 and a tilt drive assembly 120.

Wherein the cartridge mounting structure 110 is adapted to mount a cartridge. In detail, the drum mounting structure 110 is suitable for mounting the drying drum according to any of the above embodiments.

The tilt driving assembly 120 includes a first pushing structure 121, a second pushing structure 122, and a tilt driving device 123, and the first pushing structure 121 and the second pushing structure 122 are located at both sides of the cartridge mounting structure 110 and are connected to the cartridge mounting structure 110, respectively.

For example, the cartridge body has an annular cartridge wall, and a cartridge bottom and a cartridge cover located at both sides of the annular cartridge wall, wherein the first pushing structure 121 and the second pushing structure 122 are located at both sides of the cartridge body mounting structure 110, and one of the first pushing structure 121 and the second pushing structure 122 is located at a position close to the cartridge bottom, and the other is located at a position close to the cartridge cover.

Wherein, the tilt driving device 123 drives the first pushing structure 121, or the tilt driving device 123 drives the second pushing structure 122, or the tilt driving device 123 drives the first pushing structure 121 and the second pushing structure 122 (it is worth to say that, two tilt driving devices 123 may be provided at this time, two tilt driving devices 123 respectively drive the first pushing structure 121 or the second pushing structure 122 connected thereto, or one tilt driving device 123 may be provided, and the tilt driving device 123 simultaneously drives the first pushing structure 121 and the second pushing structure 122), such that when the first pushing structure 121 pushes one side of the cartridge mounting structure 110 to ascend, the second pushing structure 122 correspondingly pushes the other side of the cartridge mounting structure 110 to descend (as shown in fig. 3), or when the first pushing structure 121 pushes one side of the cartridge mounting structure 110 to descend, the second pushing structure 122 pushes the other side of the cartridge mounting structure 110 to correspondingly ascend (as shown in fig. 2). Thereby enabling tilting of the driving cylinder mounting structure 110 and thus the driving cylinder.

Compared with the prior proposal that one end (such as the bottom of the barrel) of the barrel is provided with a hinged fulcrum, the other end jacks or falls down the barrel by a jack mechanism, and the frame 111 rotates around the hinged fulcrum to realize the adjustment of the inclination angle of the barrel, the utility model adopts the mode that one end of the barrel mounting structure 110 is raised and the other end is lowered to replace the mode that one end is fixed with the fulcrum and the other end is raised or lowered, so that under the condition of realizing the same inclination angle, the equipment height change of the utility model is far smaller than the prior art, when the inclination angle of the barrel is adjusted in a large range, the change of the equipment height is reduced, thus reducing the mounting space required by the equipment, leading the utility model to be better applied to relatively narrow places such as laboratories, facilitating the installation of the external pipeline of the equipment, more fully utilizing the space of the laboratories, and under the condition of realizing the same inclination angle, the required ascending or descending degree of the cylinder is reduced, so that the required driving force is greatly reduced, the power consumption of the inclination driving device 123 is reduced, and energy conservation and emission reduction are realized.

In some embodiments, the first pushing structure 121 includes a first leg 1211, the first leg 1211 being hingedly connected to the cartridge mounting structure 110. The second pushing structure 122 includes a second leg 1221, the second leg 1221 being hingedly connected to the cartridge mounting structure 110. For example, as shown in fig. 4 and 5, the first leg 1211 and the second leg 1221 are respectively provided with a rotation shaft 125.

Wherein the first leg 1211 and the second leg 1221 are arranged to cross. Compared with a vertically arranged pushing structure, the lifting or descending of one end of the cylinder mounting structure 110 can be realized only by driving the first support leg 1211 and/or the second support leg 1221 to rotate, the driving is more labor-saving, the power consumption of the inclination driving device 123 is favorably reduced, and energy conservation and emission reduction are realized.

Further, as shown in fig. 2 and 3, the tilt driving device 123 is connected to the first leg 1211, and the tilt driving device 123 drives the first leg 1211 to rotate, such that the first leg 1211 rotates to drive the cylinder mounting structure 110 to move, and the cylinder mounting structure 110 moves to drive the second leg 1221 to rotate in the same direction as the first leg 1211 rotates. In detail, as shown in fig. 2, the tilt driving device 123 drives the first leg 1211 to rotate in the direction x1, the cylinder mounting structure 110 is driven by the first leg 1211 to tilt downward, and the cylinder mounting structure 110 drives the second leg 1221 to rotate in the direction x 2. Or as shown in fig. 3, the tilt driving device 123 drives the first leg 1211 to rotate in the direction x1 ', the cylinder mounting structure 110 is driven by the first leg 1211 to rotate and tilt upwards, and the cylinder mounting structure 110 drives the second leg 1221 to rotate in the direction x 2', so that the movement of driving two legs by one tilt driving device 123 is realized, the structure is simpler, and the driving is more labor-saving.

Further, the tilt actuator 123 has a telescoping end 1231, the telescoping end 1231 being pivotally coupled to the first leg 1211, the telescoping end 1231 extending or retracting relative to the first leg 1211 to pivot the first leg 1211, wherein the position of the telescoping end 1231 coupled to the first leg 1211 is between the midpoint of the first leg 1211 and the position of the first leg 1211 coupled to the cartridge mounting structure 110.

It is noted that as shown in fig. 2, the first leg 1211 is hingedly connected at one end to the ground or base 124 and at the other end to the cartridge mounting structure 110, wherein the location where the telescoping end 1231 is connected to the first leg 1211 can be at a midpoint a of the first leg 1211, or the location where the telescoping end 1231 is connected to the first leg 1211 can be at a location b where the first leg 1211 is connected to the cartridge mounting structure 110, or the location where the telescoping end 1231 is connected to the first leg 1211 can be anywhere between location a and location b.

Thus, the distance from the hinged end of the first leg 1211 to the ground or base 124 to the connection of the telescoping end 1231 to the first leg 1211 is longer, which is beneficial to increase the moment arm and save more effort in driving.
