DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 , the utility model provides a transport device capable of adjusting the width according to the size of goods, including a transport frame 1;

[0025] Connecting frames 2 are symmetrically arranged on both sides of the transport frame 1, and conveying members 3 with adjustable width are arranged between the connecting frames 2 and the transport frame 1. An adjusting mechanism 4 for adjusting the width between the two connecting frames 2 is arranged on the side of the transport frame 1. The adjusting mechanism 4 drives the conveying members 3 to extend through the connecting frames 2 to accommodate goods of different sizes. Multiple conveying members 3 rotate synchronously through synchronization members 5 to transport the goods. The number of conveying members 3 can be adjusted according to the actual required transportation distance.

[0026] The conveying member 3 includes a first roller 31 rotatably arranged on the side wall of the transport frame 1, and a second roller 32 rotatably arranged on the side wall of the connecting frame 2. A receiving cavity 33 is provided on the surface of the second roller 32. One end of the first roller 31 extends into the interior of the receiving cavity 33. A guide groove 34 is provided on the inner wall of the receiving cavity 33. A guide rib 35 matching the guide groove 34 is fixedly arranged on the surface of the first roller 31. The guide rib 35 is engaged with the interior of the guide groove 34.

[0027] Specifically, the second roller 32 can move linearly on the surface of the first roller 31. At this time, the overall length of the first roller 31 and the second roller 32 will increase, which corresponds to the transport frame 1, that is, the two symmetrical second rollers 32 will gradually move away from each other. No matter how the second roller 32 moves, the guide rib 35 is always engaged in the guide groove 34. Therefore, when the second roller 32 rotates, it can always drive the first roller 31 to rotate synchronously through the guide rib 35 and the guide groove 34.

[0028] The adjustment mechanism 4 includes a traction block 41 fixed to the side wall of the connecting frame 2, and a threaded rod 42 penetrating and threadedly connected to the center of the traction block 41. A protection box 43 is fixedly provided on the side of the transport frame 1, and a main shaft 44 is rotatably provided on the inner wall of the protection box 43. The two ends of the main shaft 44 are respectively connected to the two threaded rods 42. A first bevel gear 45 is fixedly provided on the main shaft 44. A first motor 46 is fixedly installed at the bottom of the protection box 43. A second bevel gear 47 meshing with the first bevel gear 45 is fixedly provided at the output end of the first motor 46.

[0029] Specifically, the first motor 46 can drive the second bevel gear 47 to rotate. Since the second bevel gear 47 is meshed with the first bevel gear 45, the second bevel gear 47 can drive the main shaft 44 to rotate through the first bevel gear 45. When the main shaft 44 rotates, it can simultaneously drive the two threaded rods 42 to rotate synchronously. Therefore, the distance moved by each traction block 41 on the surface of the corresponding threaded rod 42 is the same. Under the premise of controlling the two first motors 46 to start synchronously and have the same rotation speed, the two connecting frames 2 can move toward or relative to each other at the same rate, thereby realizing the adjustment of the distance between the two connecting frames 2.

[0030] The synchronous member 5 includes a rotating shaft 51, a synchronous wheel 52, a synchronous belt 53 and a second motor 54. The rotating shaft 51 is fixedly arranged at one end of each of the plurality of second rollers 32. Two adjacent rotating shafts 51 are connected by a synchronous wheel 52 and a synchronous belt 53. The second motor 54 is fixedly arranged on the surface of the connecting frame 2, and the output end of the second motor 54 is connected to one end of one of the rotating shafts 51.

[0031] Specifically, the second motor 54 can drive one of the rotating shafts 51 to rotate, and when the rotating shaft 51 rotates, it can drive the adjacent next rotating shaft 51 to rotate synchronously through the cooperation of the synchronous wheel 52 and the synchronous belt 53. Similarly, multiple rotating shafts 51 will rotate synchronously, thereby driving multiple conveying members 3 to transport goods in a rotating manner.

[0032] The side wall of the connecting frame 2 is provided with a limiting groove 13, and the side of the transport frame 1 is fixedly provided with a limiting rib 12 matching the limiting groove 13, and the limiting rib 12 is engaged with the inside of the limiting groove 13;

[0033] Specifically, when the connecting frame 2 moves, it can drive the limiting groove 3 on its surface to move synchronously, and the limiting groove 13 can move synchronously on the surface of the limiting rib 12. Through the cooperation of the limiting groove 13 and the limiting rib 12, the connecting frame 2 can always ensure that the longitudinal angle remains unchanged during the movement, so that the threaded rod 42 and the traction block 41 can be accurately connected to facilitate the normal movement of the connecting frame 2.

[0034] A support mechanism 6 is provided at the bottom of the transport frame 1, and the support mechanism 6 includes a plurality of support rods 61 and a bottom plate 62 connecting the bottoms of the plurality of support rods 61, a tripod 7 is fixed to the side of the support rod 61, an auxiliary plate 8 is fixed to the bottom of the tripod 7, a support plate 9 is fixed to the top of the tripod 7, the top of the support plate 9 is in contact with the bottom of the connecting frame 2, a side plate 10 is fixedly mounted on the support plate 9, and a through slot 11 for accommodating the second motor 54 is provided on the surface of the side plate 10;

[0035] Specifically, the connecting frame 2 will always move on the support plate 9 when moving. Therefore, no matter how the connecting frame 2 moves, the support plate 9 can always support it from the bottom of the connecting frame 2, thereby sharing the pressure on one end of the second roller 32, preventing the second roller 32, the first roller 31 and the rotating shaft 51 from being unable to rotate coaxially. The setting of the side plate 10 can protect the goods during transportation, and the through groove 11 can accommodate the second motor 54 to prevent the second motor 54 from hindering the normal movement of the connecting frame 2. The overall stability of the tripod 7 can increase the overall stability of the support rod 61, so as to facilitate the stable placement of the entire device.

[0036] Working principle: When it is necessary to transport larger or smaller goods, the first motor 46 is started, and the first motor 46 drives the second bevel gear 47 to rotate. The second bevel gear 47 can drive the main shaft 44 to rotate by meshing with the first bevel gear 45. When the main shaft 44 rotates, it can drive the threaded rods 42 at both ends to rotate synchronously. When the threaded rods 42 rotate, they can drive the traction block 41 to move linearly on the surface of the threaded rods 42, and then the traction block 41 drives the connecting frame 2 to move synchronously on the surface of the transport frame 1. At this time, the distance between the two connecting frames 2 will change. As the rotation direction of the threaded rods 42 is different, the distance between the two connecting frames 2 can be reduced or increased synchronously.

[0037] When the connecting frame 2 moves, it will drive the second roller 32 to move synchronously. At this time, since the first roller 31 is fixed in the axial direction, the second roller 32 will move synchronously on the surface of the first roller 31, so that the overall width of the conveying member 3 is increased. At this time, the second motor 54 is started. The second motor 54 can drive multiple rotating shafts 51 to rotate synchronously through the synchronous belt 53 and the synchronous wheel 52, so that each rotating shaft 51 drives the second roller 32 connected thereto to rotate, and the second roller 32 can drive the first roller 31 to rotate synchronously through the guide ribs 35 and the guide grooves 34. Since the outer diameter of the second roller 32 is larger than the outer diameter of the first roller 31, the second roller 32 directly contacts the bottom of the goods to transport them.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
