[0020] The present invention will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0021] See also Figure 1 The present invention provides a belt conveyor adjustment device, including a transmission body 10 and a transmission wheel group 20 arranged at both ends of the transmission body 10. The present invention also includes a conveyor belt (not shown in the figure). The conveyor belt is provided with two and combined into an inner and outer double-layer structure. The outer conveyor belt is fixed and the inner conveyor belt is movable. The transmission wheel group 20 is cooperatively connected between the two conveyor belts, and the inner conveyor belt is used to drive the transmission body 10 to move, so that the transmission body 10 follows the conveyor belt to move back and forth in a cycle.

[0022] In this embodiment, a clamping opening 11 is provided on the transmission body 10, and the cigarette box is fitted and connected in the clamping opening 11. To ensure the stability of the cigarette box clamping, ball plungers are symmetrically provided on the opposite sides of the clamping opening 11. The cigarette box is clamped and connected between the two oppositely arranged ball plungers, thereby ensuring the stability of the connection, so that the cigarette box can stably follow the conveyor belt to make a cyclic reciprocating movement, thereby reducing the volume of the equipment.

[0023] In this embodiment, the ball plunger includes a housing, a ball head slidably disposed within the housing, and a spring retractably disposed between the housing and the ball head. A portion of the ball head can be extended toward the opening of the housing under the elastic force of the spring. During assembly, any commercially available ball plunger can be used.

[0024] See also Figure 2 、 Figure 3 、 Figure 4 、 Figure 5The transmission wheel assembly 20 includes a fixed shaft 21 and a roller sleeve 24 rotatably mounted on the fixed shaft 21. There are multiple fixed shafts 21, one end of which is fixedly connected to the end of the transmission body 10. The roller sleeve 24 is a cylindrical structure with one side open and is mounted on the end of the fixed shaft 21 away from the transmission body 10. The end face of the fixed shaft 21 abuts the bottom wall of the roller sleeve 24. There are multiple rollers 26 rotatably mounted between the fixed shaft 21 and the roller sleeve 24. This allows the roller sleeve 24 to stably rotate around the axis of the fixed shaft 21. During use, the roller sleeve 24 is filled with lubricating oil to reduce friction and improve smoothness of rotation. The profile of the opening surface of the roller sleeve 24 is consistent with the profile of the cross section of the fixed shaft 21, so that the roller sleeve 24 is tightly connected to the fixed shaft 21, preventing dust from entering while reducing the overflow of internal lubricating oil, thereby improving the stability of the utility model.

[0025] Furthermore, the outer sleeve of the roller sleeve 24 is provided with a rubber sleeve 25, the length of the rubber sleeve 25 is greater than the roller sleeve 24, and the rubber sleeve 25 is in contact with the conveyor belt. The rubber sleeve 25 made of rubber improves the friction of the connection and ensures the stability of the transmission. At the same time, the rubber sleeve 25 can protect the conveyor belt and the roller sleeve 24, prevent wear, and improve the stability of the equipment.

[0026] A sealing ring 23 and a baffle 22 are also provided on the fixed shaft 21, located between the roller sleeve 24 and the transmission body 10. The sealing ring 23 is coupled to the inner wall of the rubber sleeve 25, with one side of the sealing ring 23 abutting the open surface of the roller sleeve 24, and the other side of the sealing ring 23 abutting the baffle 22. The sealing ring 23 is V-shaped and made of stainless steel, with the open surface of the V-shaped sealing ring 23 facing the baffle 22, for ease of installation. During use, the sealing ring 23 is coupled to the rubber sleeve 25 and abutted against the open surface of the roller sleeve 24. The sealing ring 23 is opened between the rubber sleeve 25 and the fixed shaft 21, so that the sealing ring 23 tightly abuts between the rubber sleeve 25 and the fixed shaft 21, thereby sealing the roller sleeve 24, further reducing dust ingress and preventing lubricating oil from overflowing.

[0027] One side of the baffle 22 abuts against the transmission body 10, and the other side of the baffle 22 abuts against the end faces of the sealing ring 23 and the rubber sleeve 25. The gasket 22 is made of copper. The use of softer copper can effectively ensure that the roller sleeve 24 is stably installed on the fixed shaft 21. In addition, the copper gasket 22 has good thermal conductivity and can withstand the high temperature generated by the high-speed rotation of the sealing ring 23, thereby improving the stability of the use of the utility model.

[0028] In this embodiment, two transmission wheel groups 20 are provided at one end of the transmission body 10. The two transmission wheel groups 20 are connected between the two conveyor belts. The internal conveyor belts are used to drive the transmission body 10 to move. When the transmission body 10 moves to the turning position, the two transmission wheel groups 20 make the steering of the transmission body 10 more stable, ensuring that the cigarette box can still be stably transmitted after the device is reduced in size.

[0029] In this embodiment, an auxiliary wheel 27 is further provided on the end of the transmission body 10 near the transmission wheel assembly 20. The axis of the auxiliary wheel 27 is perpendicular to the axis of the transmission wheel assembly 20. The auxiliary wheel 27 is rotatably mounted on the transmission body 10 and abuts the conveyor belt, further ensuring the stability of the connection between the conveyor belt and the transmission body 10. Preferably, the auxiliary wheel 27 is a common rubber wheel on the market.

[0030] The specific operation method of the present invention is: the transmission wheel set 20 is connected between the two conveyor belts, and then the cigarette box is installed on the transmission body 10, and the internal conveyor belt is used to drive the transmission body 10 to move, so that the transmission body 10 follows the conveyor belt to move back and forth in a cycle.

[0031] This utility model utilizes the transmission wheel assembly 20, which is connected between the two conveyor belts. The internal conveyor belt drives the transmission body 10, allowing the transmission body 10 to follow the conveyor belts in a reciprocating motion, and the cigarette packs also follow the transmission body 10 in a reciprocating motion, thereby reducing the size of the device. This utility model also utilizes a rubber sleeve 25, made of rubber, to increase the friction of the connection and ensure transmission stability. The rubber sleeve 25 also protects the conveyor belt and roller sleeve 24, preventing wear and tear, thereby improving the stability of the device.
