[0002] In the tobacco production process, a large number of disc-shaped thin sheet materials are used, such as cigarette paper and cigarette box lining paper in traditional tobacco; as well as thin tobacco leaf raw materials of new low-temperature non-burning tobacco and PLA materials in the cooling section. When using disc-shaped thin sheet materials, there is the problem of splicing the head of the new disc-shaped thin sheet material roll with the tail of the old disc-shaped thin sheet material roll when the material is consumed. At present, the splicing methods in the process of replacing disc-shaped thin sheet materials include glue-free splicing and glue-based splicing. In order to ensure the working efficiency of the equipment, a paper tape buffer device is designed when the disc-shaped thin sheet material is transmitted. However, during the operation, if the thin sheet material is disconnected, there is a problem of direct falling of the moving roller assembly in the buffer device. How to solve the above technical problems is a technical problem that technicians in this field urgently need to solve. Utility Model Content

[0026] Figure 1 Schematic diagram of a paper tape buffer device in an unloaded state according to an embodiment of the utility model. Figure 1 As shown, combined with Figures 2 to 4The utility model provides a paper tape buffer device, which includes a mounting plate 10, a guide rail assembly 20, a movable roller assembly 30, a brake assembly 40 and a fixed roller assembly 50. The mounting plate 10 is mounted on the equipment frame. The guide rail assembly 20 includes a guide rail pad 22 and a guide rail 21, the guide rail pad 22 is mounted on the mounting plate 10, and the guide rail 21 is mounted on the guide rail pad 22. The movable roller assembly 30 includes a movable roller mounting plate 31, a mounting plate 10, a movable roller 32, a connecting member 33, a pulley support shaft 34, and a counterweight module 35; the connecting member 33 is movably mounted on the guide rail 21 and can reciprocate along the guide rail 21; the movable roller mounting plate 31 is connected to the connecting member 33 through the pulley support shaft 34; the movable roller 32 and the counterweight module 35 are mounted on the movable roller mounting plate 31, and the counterweight module 35 is adjusted so that the center of gravity of the movable roller assembly 30 remains vertical to the center of the material; there are multiple movable rollers 32. The brake assembly 40 includes a brake block 41, a brake support shaft 42 and a bearing 43. The brake support shaft 42 is fixedly mounted on the movable roller mounting plate 31. The brake block 41 is connected to the brake support shaft 42 through the bearing 43. One end of the brake block 41 is in contact with the movable roller 32 close to the guide rail 21, and the brake block 41 can rotate around the brake support shaft 42 so that one end of the brake block 41 is in contact with the guide rail 21.

[0027] Specifically, a plurality of movable rollers 32 are mounted on the movable roller mounting plate 31, and the movable rollers 32 adjacent to the guide rail 21 can swing. The brake block 41 is an eccentric structure, and the brake block 41 can rotate around the brake support shaft 42. In a free state, the end of the brake block 41 in contact with the movable roller 32 rotates downward, and the other end of the brake block 41 moves upward. When the sheet material transmitted in the buffer device is disconnected, the brake block 41 will rotate around the brake support shaft 42, and the rotation causes the other end of the brake block 41 to rotate upward, thereby contacting the guide rail 21 and generating friction on the contact surface. Due to the transmission of force, the movable roller assembly 30 is eventually subjected to an upward force to overcome part or all of the gravity, thereby reducing the falling speed of the movable roller assembly 30. During the design, a reasonable friction factor is designed on the contact surface between the guide rail 21 and the brake block 41, so that the movable roller assembly 30 is subjected to an upward force to overcome all gravity, thereby stopping the movable roller assembly 30 from falling.

[0028] In this embodiment, a brake assembly 40 is provided, and when the sheet material is disconnected, friction is generated between the brake block 41 and the guide rail 21, partially or completely overcoming the gravity of the movable roller assembly 30, thereby reducing the falling speed of the movable roller assembly 30 or stopping the falling, thereby reducing the probability of damage to the movable roller assembly 30.

[0029] In some embodiments of the present invention, the connecting member 33 is a V-shaped wheel.

[0030] In this embodiment, the connecting member 33 is a V-shaped wheel, which is clamped on the guide rail 21, and the up and down movement of the V-shaped wheel drives the reciprocating movement of the movable roller assembly 30. Specifically, the rolling of the V-shaped wheel drives the movable roller assembly 30 to reciprocate along the guide rail 21. That is, when the movable roller assembly 30 moves, the V-shaped wheel rolls relative to the guide rail 21, and the rolling friction coefficient is smaller than the sliding friction coefficient, so the friction between the V-shaped wheel and the guide rail 21 is relatively small, so that the up and down movement of the movable roller assembly 30 is more flexible.

[0031] In some other embodiments of the present invention, the connecting member 33 is a buckle, and the buckle is buckled on the peripheral wall of the guide rail 21 .

[0032] In some embodiments of the present invention, the counterweight assembly includes a counterweight rod 37 and a counterweight block 38. The counterweight rod 37 is mounted on the movable roller mounting plate 31, and the counterweight block 38 is movably mounted on the counterweight rod 37. The position of the counterweight block 38 is adjusted to change the center of gravity of the movable roller assembly 30.

[0033] Specifically, the counterweight rod 37 is vertically mounted on the movable roller mounting plate 31, and the counterweight rod 37 is located below the movable roller 32. The counterweight block 38 is movably mounted on the counterweight rod 37, which means that the counterweight block 38 can move on the counterweight rod 37 in a direction away from or close to the movable roller mounting plate 31. With the movement of the counterweight block 38, the center of gravity of the movable roller assembly 30 changes. The connection method of the counterweight block 38 and the counterweight rod 37 can be sleeved, clamped, etc.

[0034] In this embodiment, the center of gravity of the movable roller assembly 30 is adjusted by changing the position of the counterweight block 38, which is easy to operate.

[0035] In some embodiments of the utility model, the other end of the brake block 41 is arc-shaped. In this embodiment, the brake block 41 is arranged in an arc shape, and the friction between the contact surface between the brake block 41 and the guide rail 21 can be increased during the falling process of the movable roller assembly 30.

[0036] In some embodiments of the present invention, the brake assembly 40 further includes a spring 44 , one end of the spring 44 is connected to the brake block 41 , and the other end of the spring 44 is connected to the movable roller mounting plate 31 .

[0037] In this embodiment, when the buffer device is working normally, the spring 44 is extended, and the brake block 41 is subjected to the tension of the spring 44. The brake block 41 is also subjected to the tension of the sheet material to overcome the tension of the spring 44 on the brake block 41, so that the brake block 41 rotates counterclockwise and the brake block 41 is separated from the guide rail 21. When the sheet material is disconnected, the brake block 41 is only subjected to its own gravity and the tension of the spring 44, and the brake block 41 will rotate clockwise around the brake support shaft 42, so that the brake block 41 and the guide rail 21 are in contact.

[0038] In this embodiment, a tension spring 44 is provided so that when the sheet material is broken, the brake block 41 rotates clockwise at a greater angular velocity and reacts faster.

[0039] In some embodiments of the present invention, the connecting member 33 is a V-shaped wheel, and the brake assembly 40 further includes a spring 44 , one end of the spring 44 is connected to the brake block 41 , and the other end of the spring 44 is connected to the movable roller mounting plate 31 .

[0040] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention.
