Description

Technical Field

[0001] The utility model relates to the field of cigarette packing, in particular to a novel cigarette packing device. Background Art

[0002] At present, the wrapping of cigarette strips is carried out by using a heat shrink film device, which shrinks the film by heat drying after the heat shrink film is applied, and also by using a ring baling machine for wrapping. For example, Chinese patent application No.: CN202220013818.7 discloses a surrounding wrapping mechanism, which solves the technical problem that in the existing cigarette strip wrapping, the free end of the wrapping film is easily fixed and prone to adverse conditions. The wrapping mechanism comprises an annular frame, an unwinding mechanism for unwinding the wrapping film for wrapping the material, and a cutting mechanism for cutting the wrapping film. The unwinding mechanism can move in a circle along the inner side of the annular frame, and a smoothing scraper mechanism for smoothing the cut wrapping film is provided on the annular frame. The smoothing scraper mechanism comprises a transfer mechanism and a smoothing scraper provided on the transfer mechanism.

[0003] When wrapping film is used, the number of wrapping turns is usually set to achieve the strength and stability of the wrapping film. However, due to the different number of items stacked, their weight will vary greatly, and the requirements for the strength of the wrapping film will be different. If only one number of wrapping turns is set, either waste will be generated or the wrapping strength will be reduced. Utility Model Content

[0004] Therefore, in view of the above problems, the utility model proposes a novel cigarette wrapping device, which solves the technical problem that the existing wrapping device cannot adjust the wrapping according to the height of the cigarette stack.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a new type of cigarette wrapping device, including a frame and an input conveying mechanism, a wrapping device, and an output conveying mechanism arranged on the frame according to the production line, a clamping conveyor belt is arranged on the frame above the input conveying mechanism, and the clamping conveyor belt can be lifted up and down along the frame, a first lifting mechanism for driving the clamping conveyor belt to be lifted up and down is arranged on the frame, an elastic clamping mechanism is arranged on the frame above the output conveying mechanism, and the elastic clamping mechanism can be lifted up and down along the frame, a second lifting mechanism for driving the elastic clamping mechanism to be lifted up and down is arranged on the frame, and an identification device for identifying the height of the cigarette strips is arranged at the input end of the first input conveying mechanism on the frame.

[0006] Furthermore, the input conveying mechanism is composed of two input conveying belts arranged at intervals, and a first installation space is formed between the two adjacent input conveying belts. A first pushing mechanism is arranged in the first installation space, and a first flat plate is arranged on the piston rod of the first pushing mechanism. The first flat plate can be extended into the coating device under the action of the first pushing mechanism, and the upper end surface of the first flat plate is not higher than the upper end surface of the input conveying belt.

[0007] Furthermore, the difference between the upper end surface of the first flat plate and the upper end surface of the input conveyor belt is 0-2 mm.

[0008] Furthermore, the distance between the lower end surface of the first flat plate and the upper end surface of the input conveyor belt is less than 10 mm.

[0009] Furthermore, the outer surface of the first flat plate is coated with a low friction coefficient material.

[0010] Furthermore, the output conveying mechanism is composed of two output conveying belts arranged at intervals, and a second installation space is formed between the two adjacent output conveying belts. A second pushing mechanism is arranged in the second installation space, and a second flat plate is arranged on the piston rod of the second pushing mechanism. The second flat plate can be extended into the coating device under the action of the second pushing mechanism, and the upper end surface of the second flat plate is not higher than the upper end surface of the output conveying belt.

[0011] Furthermore, the elastic clamping mechanism includes a support plate, a mounting frame arranged below the support and capable of being raised and lowered by guide pillars, and a plurality of clamping rollers rotatably arranged on the mounting frame. A tensioning spring is arranged on the circumferential outer side of each guide pillar between the mounting frame and the support plate.

[0012] Furthermore, a rubber material layer is provided on the outer circumferential side of the clamping roller.

[0013] By adopting the above technical solution, the beneficial effects of the utility model are:

[0014] 1. This solution uses a height recognition device, such as a recognition system with a camera, to achieve height recognition, and then uses a first lifting mechanism to achieve the lifting of the clamping conveyor belt, thereby achieving the clamping output of the cigarette stack. When the output enters the film wrapping device, the film wrapping device realizes film wrapping, and then enters the output conveying mechanism, and uses an elastic clamping mechanism to achieve elastic clamping, and then achieves output. During the transportation process, the packaged cigarette stack can maintain contact with at least one of the clamping conveyor belt and the elastic clamping mechanism when passing through the film wrapping device.

[0015] 2. The width of the first installation space is relatively small, usually set to 1 / 3 to 1 / 2 of the width of the cigarette. Through the setting of the first pushing mechanism and the first flat plate, it can be achieved that at least one cigarette can be supported after being output, and due to the existence of the film, the remaining cigarettes that are not supported by the first flat plate will be affected by the support of the first flat plate due to the coating of the film, thereby achieving a certain degree of support. The support of the first flat plate is only an auxiliary, mainly to prevent some posture changes of the cigarettes during the film coating process. Adding the first flat plate can greatly reduce the occurrence of such defects. In addition, the difference between the upper end face of the first flat plate and the upper end face of the input conveyor belt is 0-2mm, so this setting can achieve a better support effect. The distance between the lower end face of the first flat plate and the upper end face of the input conveyor belt is less than 10mm, which can effectively reduce the impact of the first flat plate being pulled out after the film coating. The outer surface of the first flat plate is coated with a low friction coefficient material, which can facilitate the removal of the first flat plate.

[0016] 3. Similarly, the output conveying mechanism is also set up like the input conveying mechanism. Through the setting of the second installation space, the second pushing mechanism, and the second flat plate, the second flat plate can cooperate with the first flat plate to achieve the film wrapping of the cigarette. When the cigarette just leaves the input conveying mechanism and enters the film wrapping device, the second flat plate is extended for support. At this time, the film wrapping has not yet begun. At the same time, the first flat plate will also be extended. After the film wrapping begins, the second flat plate will be withdrawn. When the cigarette film wrapping device enters the elastic clamping mechanism, the first flat plate will also be withdrawn. In this way, the support for the cigarette is completed, thereby assisting the completion of the film wrapping.

[0017] 4. The setting of the elastic clamping mechanism can achieve better clamping of the cigarettes, so as to achieve the output coordination after the cigarettes are wrapped. Due to the existence of the clamping roller and the tensioning spring, this clamping is flexible, and its purpose is to achieve the stability of the wrapping and the stability of the cigarette output.
