[0020] The technical solution of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] This utility model provides a reverse transmission device, such as Figure 1 As shown, the system includes a frame 1, a first pulley 3 for driving a first conveyor belt 2, a second pulley 5 for driving a second conveyor belt 4, a reverse transmission mechanism 6, and a drive component 7. The first pulley 3 and the second pulley 5 are rotatably mounted on the frame 1, and the drive component 7 is fixedly mounted on the frame 1. The drive component 7 is connected to the first pulley 3, and the first pulley 3 and the second pulley 5 are connected via the reverse transmission mechanism 6. The reverse transmission mechanism 6 is used to drive the second pulley to rotate in the opposite direction when the first pulley rotates.

[0022] The reverse transmission device provided by this utility model connects the first pulley and the second pulley through a reverse transmission mechanism. When the driving component drives the first pulley to rotate, the reverse transmission mechanism drives the second pulley to rotate. The first pulley and the second pulley rotate in opposite directions, thereby achieving opposite movement directions for the first conveyor belt and the second conveyor belt. Only one driving component is required, resulting in a simple structure that saves space and cost.

[0023] The reverse transmission mechanism can have various structures, and this utility model provides two preferred structures.

[0024] The first structure, the reverse transmission mechanism 6 includes a first cylindrical gear and a second cylindrical gear that mesh with each other, the first cylindrical gear being fixedly connected to the first pulley, and the second cylindrical gear being fixedly connected to the second pulley.

[0025] Preferably, the driving component 7 is connected to the first pulley 3, specifically: the first pulley 3 is fixedly sleeved on the first transmission shaft, and the driving component is connected to the first transmission shaft. The second pulley is sleeved on the second transmission shaft through a bearing; the first transmission shaft is rotatably mounted on the frame, and the second transmission shaft is fixedly mounted on the frame.

[0026] During operation, the drive unit drives the first transmission shaft to rotate, and at the same time the first pulley 3 rotates, which drives the first cylindrical gear to rotate. Then the second cylindrical gear, which meshes with the first cylindrical gear, rotates in the opposite direction, thereby driving the second pulley 5 to rotate on the second transmission shaft. The rotation direction of the second pulley 5 is opposite to that of the first pulley 3.

[0027] In the above structure, two pulleys are connected by two meshing cylindrical gears, which is a simple structure.

[0028] The second structure, such as Figure 2 As shown, the reverse transmission mechanism 6 includes two coaxially arranged first bevel gears 61 and N second bevel gears 62. One first bevel gear 61 is fixedly connected to the first pulley 3, and the other first bevel gear 61 is fixedly connected to the second pulley 5. The N second bevel gears 62 are rotatably mounted on the frame 1 via a rotating shaft 63, positioned between the two first bevel gears 61. Each second bevel gear 62 meshes with two first bevel gears 61 on each side. N is an integer greater than or equal to 1. For example, N is 1, 2, 3, 4, or 5. The more second bevel gears there are, the greater the transmitted torque, and the greater the driving force transmitted by the reverse transmission mechanism, ensuring that the first pulley rotates well and drives the second pulley to rotate in the opposite direction. Preferably, N is 2, 3, or 4, which effectively drives the first bevel gear connected to the second pulley to rotate, while preventing excessive torque from damaging the second bevel gears.

[0029] In the above structure, two pulleys are connected by two first bevel gears 61 and multiple second bevel gears 62, so that the two pulleys can be arranged coaxially, resulting in a compact structure, high strength, and easy processing.

[0030] Preferably, N is 1, and there is one second bevel gear 62.

[0031] Preferably, N is 2, and there are two second bevel gears 62, which are coaxially arranged.

[0032] Preferably, the driving component 7 is connected to the first pulley 3, specifically: the first pulley 3 is fixedly sleeved on the third transmission shaft, and the driving component 7 is connected to the third transmission shaft. The second pulley 5 is sleeved on the fourth transmission shaft via bearings. The third transmission shaft is rotatably mounted on the frame 1, and the fourth transmission shaft is fixedly mounted on the frame 1.

[0033] During operation, the drive unit 7 drives the third transmission shaft to rotate, and at the same time the first pulley 3 rotates, the first bevel gear 61 connected to it rotates, which drives the second bevel gear 62 to rotate, and then drives the first bevel gear 61 connected to the second pulley 5 to rotate in the opposite direction, thereby driving the second pulley 5 to rotate on the fourth transmission shaft. The rotation direction of the second pulley is opposite to the rotation direction of the first pulley.

[0034] Preferred, such as Figure 3 As shown, the driving component 7 is connected to the first pulley 3. Specifically, the first pulley 3 is fixedly sleeved on the fifth transmission shaft, and the driving component 7 is connected to the fifth transmission shaft. The second pulley 5 is sleeved on the fifth transmission shaft via a bearing, and the fifth transmission shaft is rotatably mounted on the frame 1. In this structure, the first pulley 3 and the second pulley 5 are sleeved on the same transmission shaft, making the structure simpler and more compact.

[0035] During operation, the drive unit 7 drives the fifth transmission shaft to rotate, and at the same time the first pulley 3 rotates, the first bevel gear 61 connected to it rotates, which drives the second bevel gear 62 to rotate, and then drives the first bevel gear 61 connected to the second pulley 5 to rotate in the opposite direction, thereby driving the second pulley 5 to rotate on the fifth transmission shaft. The rotation direction of the second pulley is opposite to the rotation direction of the first pulley.

[0036] This utility model also provides a yarn tube conveying device, including the reverse transmission device described in the above embodiment, a first conveyor belt 2, a second conveyor belt 4, a first transmission wheel, and a second transmission wheel. The first transmission wheel and the second transmission wheel are respectively connected to the frame 1. The first conveyor belt 2 is mounted on the first transmission wheel and the first pulley 3, and the second conveyor belt 4 is mounted on the second transmission wheel and the second pulley 5. During operation, the tray for carrying the yarn tube is located on the first conveyor belt 2 or the second conveyor belt 4. When the drive unit drives the first pulley to rotate, it drives the second pulley to rotate through the reverse transmission mechanism, thereby driving the first conveyor belt and the second conveyor belt to move. Since the first pulley and the second pulley rotate in opposite directions, the first conveyor belt and the second conveyor belt move in opposite directions.

[0037] Preferably, the axes of the first drive wheel, the second drive wheel, the first pulley 3, and the second pulley 5 are located on the same horizontal plane. The diameters of the first drive wheel, the second drive wheel, the first pulley 3, and the second pulley 5 are equal and their axes are located on the same horizontal plane, so that the upper surfaces of the first conveyor belt and the second conveyor belt are on the same plane, and the transfer of the pallet from one conveyor belt to another will be smoother.

[0038] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
