Description

Technical Field

[0001] This utility model relates to the field of conveying technology, specifically to a buffer conveying device for cigarette packs after cutting. Background Technology

[0002] In tobacco processing, after the tobacco packs are opened, they are divided and cut into small pieces for subsequent processes such as vacuum rehydration of the tobacco pieces, ultimately producing the finished tobacco product. The tobacco packs are located inside the tobacco box, whose standard dimensions are generally 1115×690×725mm (length×width×height). The standard weight of a tobacco pack is approximately 200kg. It is made by compressing re-dried tobacco sheets using a hydraulic press, resulting in a relatively high density. Even after being divided into small pieces by a slitting machine, if it is cut into 4 pieces, each piece weighs approximately 50kg; if it is cut into 5 pieces, each piece weighs approximately 40kg. Generally, it is divided into about 5 pieces.

[0003] Generally, the cigarette block outlet of most "cigarette pack slitting machines" is higher than the conveyor belt of the output machine, with some differences exceeding 1 meter. This difference in height is intended to ensure smooth conveying, but it also brings problems such as loud noise and impact sound when the cigarette blocks fall on the conveyor belt, which can often be clearly heard from tens of meters away. Furthermore, the long-term impact of the cigarette blocks on the output machine can easily damage the equipment.

[0004] A review of utility model publication CN 214483206 U reveals a buffer device for unloading tobacco packages in a vertical slitting machine. This device includes a frame, a buffer platform located at the discharge end of the cutting table for the cut tobacco blocks to slide onto the discharge conveyor belt, and a buffer curtain located above the discharge end of the buffer platform to decelerate the tobacco blocks sliding on the buffer platform. With the buffer curtain, when a fast-moving tobacco block collides with the buffer curtain, some of the tobacco block's kinetic energy is transferred to the buffer curtain, effectively slowing it down. However, since the cut tobacco blocks weigh 40-50 kg, which is still relatively heavy, the buffer curtain's blocking and buffering effect is weak. Furthermore, the buffer platform has a complex structure including the buffer curtain and support sleeves, making its manufacturing process cumbersome. Therefore, this utility model provides a buffer conveying device for tobacco packages after slitting, which can simply and effectively buffer the tobacco blocks. Utility Model Content

[0005] This invention provides a buffer conveying device for tobacco packs after they have been cut, which can simply and effectively buffer the tobacco blocks.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A buffer conveying device for cigarette pack slitting includes an upper conveying device, a slitting machine, a lower conveying device, and a buffer assembly. The upper conveying device is located above the lower conveying device, the slitting machine is located at the end of the upper conveying device, and a buffer assembly is provided between the end of the upper conveying device and the beginning of the lower conveying device. The buffer assembly includes side plates and spring sheets. The side plates are connected to both sides of the upper and lower conveying devices, and spring sheets are connected between the side plates. The spring sheets are arc-shaped, and the bottom end of the spring sheets is provided with an arc strip. The arc direction of the arc strip is opposite to the arc direction of the spring sheets. The top end of the spring sheets is connected to the end of the upper conveying device.

[0008] Optionally, the top of the spring is provided with an installation strip, and the spring is connected to the end of the upper conveying device by the installation strip and the upper screw.

[0009] Optionally, mounting plates are provided at both ends of the mounting strip, and the mounting plates are connected to the side plates by side screws.

[0010] Optionally, the central angle of the spring sheet is 90-120°, the thickness is 3-5mm, and the distance between the bottom arc of the spring sheet and the conveying surface of the lower conveying device is 200-300mm.

[0011] Optionally, the arc strip and the spring sheet are integral structures, and the radius of the arc strip is 5-10mm.

[0012] Optionally, the spring sheet is a spring steel sheet with a thickness of 4mm.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention features a buffer assembly between the upper and lower conveying devices. The buffer assembly includes an arc-shaped spring sheet, which effectively mitigates the impact of the falling smoke block and eliminates the impact noise on the lower conveying device. The entire process is quiet and smooth. Because the spring sheet is made of spring steel with an arc design, it has good elasticity. Even when the smoke block is large, the smoke block will press the end of the spring sheet into contact with the lower conveying device and then rebound. During this process, the elasticity of the spring sheet can also effectively buffer the impact of the large-mass smoke block. Compared with the prior art, it has a better buffering effect on large-mass smoke blocks and is simpler in structure. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0022] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] refer to Figure 1-2 As shown, this utility model provides a buffer conveying device for cigarette packs after slitting, including an upper conveying device 2, a slitting machine 3, a lower conveying device 10, and a buffer assembly. The upper conveying device 2 is located above the lower conveying device 10, the slitting machine 3 is located at the end of the upper conveying device 2, and a buffer assembly is provided between the end of the upper conveying device 2 and the beginning of the lower conveying device 10. The buffer assembly includes side plates 5 and spring pieces 9. The side plates 5 are connected to both sides of the upper conveying device 2 and the lower conveying device 10, and the spring pieces 9 are connected between the side plates 5.

[0024] Specifically, the central angle of the spring sheet 9 is 90-120°, the thickness is 3-5mm, the radius of the arc of the spring sheet 9 is set according to the height difference of the conveying device, and the distance between the bottom of the arc of the spring sheet 9 and the conveying surface of the lower conveying device 10 is 200-300mm. Preferably, in this embodiment, the spring sheet 9 is a spring steel sheet with a thickness of 4mm.

[0025] During operation, after the cigarette pack 1 is cut into cigarette blocks 7, it falls onto the spring sheet 9 and then along the arc surface onto the lower conveyor device 10. For lighter cigarette blocks, the spring sheet 9 will not deform and only needs to be cushioned by the arc surface. When the cigarette block is heavier, it will press the spring sheet 9 downward or even make the spring sheet contact the lower conveyor device 10. During this process, since the spring sheet 9 is a spring steel sheet with elasticity, it will apply elastic force to the cigarette block, thereby cushioning the falling cigarette block as it falls onto the lower conveyor device 10.

[0026] The spring sheet 9 is arc-shaped, and an arc strip 11 is provided at the bottom end of the spring sheet 9. Specifically, the arc strip 11 and the spring sheet 9 are integral structures, and the radius of the arc strip 11 is 5-10mm. During the processing, the end of the spring sheet 9 can be rolled again to form the arc strip 11. The arc direction of the arc strip 11 is opposite to that of the spring sheet 9. The top end of the spring sheet 9 is connected to the end of the upper conveying device 2. In some embodiments, the top end of the spring sheet 9 can also be connected to the bottom of the slitting machine 3.

[0027] refer to Figure 3-4 As shown, in order to connect the top end of the spring 9, the top end of the spring 9 is provided with a mounting strip 12. The spring 9 is connected to the end of the upper conveying device 2 through the mounting strip 12 and the upper screw 6. In addition, mounting plates 8 are provided at both ends of the mounting strip 12. The mounting plates 8 are connected to the side plates 5 through the side screws 4.
