[0020] The following describes the details and working principles of the embodiments and examples of the present invention in conjunction with the accompanying drawings. This quick-detachable conveying device includes a frame 1, a driving roller 2, and a conveying component 3. The driving roller 2 is rotatably mounted on the frame 1 at both ends and is typically driven by a motor 9. The conveying component 3 includes a bracket 5, a conveyor belt 6, and a drive wheel assembly 8. The drive wheel assembly 8 includes a drive wheel rotatably mounted on the bracket 5. The conveyor belt 6 is wound around the drive wheel. The conveyor belt 6 includes a conveying section 61 and a transmission section 62. The outer surface of the transmission section 62 contacts the outer surface of the driving roller 2, and the driving roller 2 drives the conveyor belt 6. The conveyor belt 6 of the present invention only contacts the driving roller 2 on its outer surface. The conveyor belt 6 is entirely mounted outside the driving roller 2. The motor drives the driving roller to rotate, which in turn drives the conveyor belt to achieve conveying. The present invention avoids the sleeved arrangement of the conveyor belt 6 and the driving roller 2 in the prior art. Therefore, when replacing the conveyor belt 6, there is no need to remove the driving roller 2; only the conveyor belt 6 needs to be removed from the drive wheel, making replacement quick and convenient. The transmission section of the present invention is in surface contact with the active roller, so the transmission is stable, and the surface contact causes little damage to the conveyor belt, thereby extending the service life.

[0021] To further enhance the convenience of replacing the conveyor belt 6, one end of the transmission wheel is rotatably connected to the bracket 5, and the other end of the transmission wheel is free. The conveyor belt 6 enters from the free end of the transmission wheel and is wound around the transmission wheel. Because the conveyor belt 6 is fastened from one end of the transmission wheel, two sets of transmission wheels 8 and two conveyor belts 6 can be installed on one bracket 5, and the transmission wheels of the two transmission wheel sets 8 are arranged symmetrically.

[0022] The transmission wheels of the transmission wheel group 8 include a pressing transmission wheel and a conveying transmission wheel. The conveying transmission wheel includes a front transmission wheel 84 and a rear transmission wheel 85. The inner surface of the conveyor belt 6 passes around the front transmission wheel 84 and the rear transmission wheel 85, and the conveyor belt between the front transmission wheel 84 and the rear transmission wheel 85 is a conveying section 61. The conveying section acts on the material to realize the conveying of the material. In the accompanying drawings, the active roller 2 is at the bottom and the conveying section 61 of the conveyor belt is at the top; it can also be that the active roller is at the top and the conveying section of the conveyor belt is at the bottom. The pressing transmission wheel includes a first transmission wheel 81 and a second transmission wheel 82. The inner surface of the conveyor belt passes around the first transmission wheel 81 and the second transmission wheel 82. The first transmission wheel 81 is pressed against the active roller 2. The transmission section of the conveyor belt is between the first transmission wheel and the second transmission wheel. The first transmission wheel is pressed against the active roller to ensure that the transmission section of the conveyor belt contacts and transmits with the active roller. The second transmission wheel and the active roller can be pressed together or separated, and both can make the transmission section of the conveyor belt cover the outside of the active roller. Among them, it is better that the second transmission wheel is pressed together with the active roller or the second transmission wheel is close to the active roller. If the first transmission wheel and the second transmission wheel are both pressed together with the active roller, the conveyor belt between them is the transmission section.

[0023] The first transmission wheel 81 can be kept in press fit with the active roller 2 by a spring. In the figure, the conveying component 3 also includes a torsion arm assembly 7 for pressing the first transmission wheel with the active roller 2, and the torsion arm assembly 7 includes a torsion arm support foot 73, a first arm 71 and a second arm 72. The first arm 71 and the second arm 72 are connected and swingably set on the torsion arm support foot 73. The first arm and the second arm are connected, and the two can be fixedly connected or can be an integral structure. The torsion arm support foot 73 is connected to the bracket 5, the first transmission wheel 81 is rotatably mounted on the first arm 71, and the second arm 72 is rotatably mounted with the third transmission wheel 83. The conveyor belt 6 passes around the third transmission wheel 83, the first transmission wheel 81 and the second transmission wheel 82 in sequence, and the outer surface of the conveyor belt passes around the third transmission wheel 83. The first arm and the second arm can be on the same straight line, see attached Figure 3 , the first arm and the second arm form an angle, which is more effective when used in the same straight line relative to the first arm and the second arm. When the conveyor belt 6 is tensioned and the third transmission wheel 83 is subjected to an upward force, the second arm 72 swings counterclockwise and the first arm 71 swings clockwise, causing the first transmission wheel 81 to press on the active roller 2. The greater the upward force on the third transmission wheel 83, the greater the downward pressure of the first transmission wheel 81. It is best to use an elastic belt for the conveyor belt 6, which has a certain degree of contractility and a better pressing effect. The torsion arm assembly 7 of the present invention has a simple structure, which enables the first transmission wheel 81 to maintain a stable pressing state with the active roller 2, ensuring that the transmission section 62 of the conveyor belt is in contact with the active roller 2, and realizing stable power transmission.

[0024] The torsion arm mounting foot is movably arranged on the support 5, and the height position of the torsion arm mounting foot on the support 5 is adjusted. Not only the tension of the conveying belt is adjusted, but also when the conveying belt 6 is replaced, the distance between the conveying driving wheel and the pressing driving wheel is reduced by moving the torsion arm mounting foot, so that the conveying belt 6 is loosened and the conveying belt 6 is conveniently removed from the driving wheel; after the new conveying belt 6 is replaced, the torsion arm mounting foot is reversely moved, the distance between the conveying driving wheel and the pressing driving wheel is increased, and the conveying belt 6 is tensioned. The cross beam 4 is arranged on the rack 1, the support 5 is movably arranged on the cross beam 4, and the lateral position of the support 5 on the rack 1 is adjusted. The conveying component 3 is arranged in several groups, and the conveying components 3 are arranged in the axial direction of the driving roller 2. According to the conveying width, the conveying component 3 is rotated, and according to the conveying position, the lateral position of the conveying component 3 on the rack 1 is adjusted, so that the conveying requirement can be flexibly met.
