TECHNICAL FIELD

[0001] The utility model belongs to tobacco logistics technical field, and specifically is a piece of cigarette unpacking device. BACKGROUND

[0002] At present, in the tobacco logistics industry, the unpacking operation of piece of cigarette is an important and basic process. With the continuous development of the tobacco industry, the logistics transportation scale of piece of cigarette is expanding, and higher requirements are put forward for the efficiency and quality of unpacking operation, so the automatic unpacking device emerges as the times require.

[0003] The Chinese utility model patent with the publication number CN220743629U discloses a piece of cigarette unpacking and replenishing device, which guides piece of cigarette into the material guiding channel in a set posture by using the material guiding mechanism, and then performs unpacking operation on piece of cigarette by the unpacking cutter located above the material guiding channel. The disadvantage of the device is that it only drives piece of cigarette to collide with the unpacking cutter to complete the unpacking operation by the roller at the bottom, which is easy to cause piece of cigarette to be stuck in the material guiding channel due to insufficient driving force, affecting the continuity of piece of cigarette unpacking. UTILITY MODEL CONTENT

[0004] To solve the technical problem that the existing piece of cigarette unpacking device is easy to cause piece of cigarette to be stuck in the material guiding channel due to insufficient driving force, affecting the continuity of piece of cigarette unpacking in the background technology, the utility model provides a piece of cigarette unpacking device.

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0006] A piece of cigarette unpacking device, which comprises a conveying mechanism and an unpacking cutter head installed directly above the conveying mechanism, wherein the conveying mechanism comprises two conveying racks arranged at intervals and a conveying belt installed between the two conveying racks; and further comprises a moving mechanism and a clamping mechanism.

[0007] The unpacking cutter head is installed on the moving mechanism, and the moving mechanism is used to drive the unpacking cutter head to move back and forth along the conveying direction of piece of cigarette.

[0008] Each of the two conveying racks is provided with one clamping mechanism, and the clamping mechanism comprises:

[0009] A telescopic mechanism is fixedly installed at one end on the conveying rack, and the other end is provided with a telescopic end extending to the middle part of the conveying belt.

[0021] Preferably, the unpacking cutter head is in the shape of a triangular pyramid. The unpacking cutter head in the shape of a triangular pyramid has a unique geometric shape, can cut into the adhesive tape and the gap of the piece cigarette box more effectively, improves the unpacking efficiency, and opens the box while cutting, thereby simplifying the subsequent process.

[0022] Preferably, the head of the unpacking cutter head is downwardly inclined.

[0023] Preferably, a vertical rod is arranged between the moving block and the lifting plate, one end of the vertical rod is fixedly connected with the bottom of the moving block, and the other end penetrates through the lifting plate and is fixedly connected with a third limiting plate. The structure of the vertical rod and the third limiting plate ensures that the lifting plate can stably lift and lower under the driving of the electric telescopic rod, avoids shaking or tilting of the lifting plate, and ensures the working stability of the unpacking cutter head.

[0024] Preferably, guide bars are provided on both sides of the electric slide rail, and a guide groove is provided on the top of the moving block to cooperate with the guide bars.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0026] 1. The cigarette pack to be opened is clamped by the clamping mechanism, and then the opening knife head is driven by the moving mechanism to complete the opening operation. After the opening is completed, the clamping mechanism releases the cigarette pack and the next step can be continued. The cigarette pack will not be stuck in the opening device due to insufficient driving force, thus ensuring the continuity of the cigarette pack opening process.

[0027] 2. By setting a spring between the first plate and the second plate, the impact of external force can be effectively buffered, preventing the cigarette packs from deforming due to compression and protecting the internal cigarette packs from damage.

[0028] 3. The electric slide rail can drive the moving block to move flexibly in the horizontal direction, and the electric telescopic rod can precisely control the vertical height of the lifting plate. Combined with the triangular pyramidal box-opening knife head, which has good cutting and box-opening performance, it not only improves the success rate of box opening, but also effectively enhances the adaptability of the box-opening mechanism to opening cigarettes of different heights.
