[0039] The frame 1 is provided with a plurality of conveying units 2 arranged in parallel, and the distance between the conveying units 2 is adjusted by the width adjustment assembly 3. The conveying unit 2 includes a conveyor belt 21 and a support bar 22 for supporting the conveyor belt 21. The conveyor belt 21 is wound around rollers 23 at the head and tail ends of the support bar 22 and moves around the rollers 23 at the head and tail ends of the support bar 22 through the driving assembly 6.

[0040] The support bar 22 is connected to the frame 1 through a base 24, the length of the support bar 22 is adjusted by the telescopic assembly 4, one end of the support bar 22 is connected to the lifting assembly 5, and the other end is hinged to the base 24. When the lifting assembly 5 is lifted, the support bar 22 forms a predetermined angle.

[0041] The frame 1 is fixedly connected to the horizontal plane. The base 11 is disposed above the frame 1 and fixedly connected to the frame 1. A conveying unit 2 is provided above the base 11, and each conveying unit 2 corresponds to a base 11 and is connected to the frame 1. A lifting assembly 5 is disposed on the base 11. When one end of the support bar 22 is lifted by the lifting assembly 5, the support bar 22 rotates around the hinge point and forms a certain angle with the horizontal plane.

[0042] In one embodiment, the conveying unit 2 includes a first conveying unit 2a and a second conveying unit 2b. The second conveying units 2b are respectively provided on both sides of the first conveying unit 2a, and the second conveying unit 2b approaches or moves away from the first conveying unit 2a through a width adjustment assembly 3. The first conveying unit 2a includes a plurality of support bars 22 arranged in parallel.

[0043] In this embodiment, the number of the conveying units 2 is 3, one of which is the first conveying unit 2a, and two second conveying units 2b symmetrically arranged on both sides of the first conveying unit 2a. The first conveying unit 2a does not move in the horizontal direction, and the width of the conveying area is adjusted by adjusting the distance between the second conveying units 2b on both sides. The difference between the first conveying unit 2a and the second conveying unit 2b lies in the different widths and whether there is a width adjustment assembly 3 to drive the movement in the horizontal direction.

[0044] In one embodiment, the width adjustment assembly 3 includes a first motor 31, a transmission rod 32, a gear 33, a rack 34, a first guide rail 35 and a first slider 36. The first motor 31 is disposed on the base 11. The output end of the first motor 31 is connected to the symmetrically arranged transmission rods 32. The end of the transmission rod 32 is provided with a gear 33, and the gear 33 meshes with the rack 34. The rack 34 and the first guide rail 35 are respectively fixedly connected to the frame 1, and the arrangement directions of the rack 34 and the first guide rail 35 are perpendicular to the arrangement direction of the support bar 22. A first slider 36 is provided on the lower side of the base 24, and the first slider 36 is connected to the first guide rail 35 in a matching manner.

[0045] The width adjustment assembly 3 adopts a gear-rack transmission method. When the first motor 31 works, the transmission rod 32 rotates to drive the gear 33 to rotate. The gear 33 meshes with the rack 34, and the gear 33 rotates and moves along the rack 34, thereby driving the base 24 to move. The arrangement directions of the first guide rail 35 and the rack 34 are parallel, and the first slider 36 slides along the first guide rail 35, that is, the base 24 moves along the direction of the first guide rail 35, so that the support bar 22 of the second conveying unit 2b approaches or moves away from the middle first conveying unit 2a along the direction of the first guide rail 35.

[0046] In one embodiment, the support bar 22 includes a fixed portion 221, a movable portion 222, a second guide rail 223, and a second slider 224. The first end of the fixed portion 221 and the last end of the movable portion 222 are overlapped, and rollers 23 are respectively provided at the last end of the fixed portion 221 and the first end of the movable portion 222.

[0047] One end of the fixed portion 221 is connected to the lifting assembly 5, and the other end is hinged to the base 24. The second guide rails 223 are arranged on both sides of the movable portion 222 and are fixedly connected to the movable portion 222. The movable portion 222 covers the fixed portion 221, and the movable portion 222 forms a depression inward. The fixed portion 221 is located in the depression of the movable portion 222, and the outer shapes of the movable portion 222 and the fixed portion 221 match. Second sliders 224 are provided on both sides of the fixed portion 221, and the second sliders 224 are connected to the second guide rails in a matching manner, and the second sliders 224 slide along the second guide rails 223. The telescopic assembly 4 drives the movable portion 222 to move along the direction of the second guide rail 223.

[0048] The telescopic assembly 4 drives the movable portion 222 to move along the direction of the second guide rail 223, so that the area for carrying the conveyor belt 21 becomes longer, thereby realizing the adjustment of the conveying length. The movable portion 222 and the fixed portion 221 adopt a stacked design. The cross-section of the movable portion 222 is concave, and the cross-section of the fixed portion 221 is rectangular, and the two match each other.

[0049] In one embodiment, the telescopic assembly 4 includes a second motor 41, a telescopic rod 42, a collar 43, and a push block 44. The second motor 41 is arranged on the fixed portion 221, and the output end of the second motor 41 is connected to the telescopic rod 42 to drive the telescopic rod 42 to rotate. The collar 43 is fixedly connected to the movable portion 222 through the push block 44. The collar 43 is sleeved on the telescopic rod 42. The collar 43 is provided with internal threads, and the telescopic rod 42 is provided with external threads matching the internal threads of the collar 43.

[0050] The telescopic rod 42 is specifically a screw rod. The movement of the telescopic assembly 4 is specifically screw transmission. The arrangement direction of the telescopic rod 42 is parallel to the movement direction of the movable portion 222. The second motor 41 drives the telescopic rod 42 to rotate. The rotation of the telescopic rod 42 causes the collar 43 to move along the direction of the telescopic rod 42. The collar 43 is connected to the movable portion 222 through the push block 44, thereby driving the movable portion 222 to move along the second guide rail 223.

[0051] It further includes a buffer assembly 7. The buffer assembly 7 includes a movable roller 71 and a fixed roller 72. The fixed roller 72 is fixedly connected to the fixed portion 221. The movable roller 71 is located above the fixed roller 72. The movable roller 71 is fixedly connected to the push block 44 and moves synchronously with the movable portion 222. As Figure 4 shown by the green identification conveyor belt, the conveyor belt located below the support bar 22 winds around the movable roller 71 and the fixed roller 72 in an S shape.

[0052] The conveyor belt 21 between the fixed roller 72 and the movable roller 71 is a buffer conveyor belt 21, which is used to accommodate the length change of the conveyor belt on the upper side of the strain support bar 22. The position of the fixed roller 72 is fixed, and the movable roller 71 moves synchronously with the moving part 222. When the moving part 222 moves to make the conveying area longer, the length of the conveyor belt 21 on the upper side of the support bar 22 becomes longer, and the lower movable roller 71 approaches the fixed roller 72, so that the length of the conveyor belt 21 between the movable roller 71 and the fixed roller 72 becomes shorter. Similarly, when the moving part 222 moves to make the conveying area shorter, the length of the conveyor belt 21 on the upper side of the support bar 22 becomes shorter, and the lower movable roller 71 moves away from the fixed roller 72, so that the length of the conveyor belt 21 between the movable roller 71 and the fixed roller 72 becomes longer.

[0053] In addition, a guide groove 225 is provided in the middle of the fixing part 221, and the surface of the moving part 222 is embedded in the guide groove 225 and matches the guide groove 225. The guide groove 225 is used to limit the relative lateral movement between the moving part 222 and the fixing part 221.
