Description

Technical Field

[0001] This utility model relates to a cigarette pack rejection device, belonging to the field of cigarette pack quality inspection technology. Background Technology

[0002] In cigarette production, cigarette cartons are usually placed on a conveyor belt to complete the cigarette packaging process. In order to improve the quality of cigarettes, it is necessary to inspect the cigarette cartons on the conveyor belt. When defective cigarette cartons are detected, they need to be rejected.

[0003] According to the applicant, the current common method involves setting up a cigarette storage box on one side of the conveyor belt to hold defective cigarette packs, and then using a cigarette pushing device on the other side to push the cigarette packs into the storage box. However, since both the storage box and the pushing device are located on both sides of the conveyor belt, they occupy a large area, and there is significant room for improvement in terms of both production line layout and cost.

[0004] The applicant's search revealed that Chinese Patent Publication No. CN222402407U discloses a cigarette sorting and conveying device. This device divides a conveyor belt into a first conveyor belt and a second conveyor belt, and places a cigarette storage box below both belts. The second conveyor belt needs to be flipped downwards to form a sorting and conveying state to remove defective cigarette packs, thus reducing the occupied area. However, the downward flipping of the second conveyor belt increases production and installation costs, and also reduces conveying efficiency, thus limiting the application scope of this device. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to propose a cigarette strip removal device that occupies little space and has a low cost.

[0006] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a cigarette strip removal device, including a cigarette strip conveying channel, a cigarette clamping and conveying mechanism, a removal mechanism and a cigarette storage box, wherein the cigarette strip conveying channel is fixedly installed on the frame and the width of the cigarette strip conveying channel corresponds to the length of the cigarette strip;

[0007] The cigarette-clamping conveying mechanism includes two cigarette-clamping conveyor belts respectively arranged on both sides of the cigarette conveying channel;

[0008] The cigarette conveying channel has a hollow section, the length of which is greater than the width of the cigarette pack, and the cigarette storage box is located below the hollow section;

[0009] The removal mechanism is located above the hollowed-out section and can move up and down, having a downward-pressing smoke removal state and a normal transmission state located above the hollowed-out section.

[0010] In use, the present invention connects the cigarette conveying channel to the conveying channel of the cigarette inspection production line. During normal transmission, when a defective cigarette is detected, the defective cigarette is pushed into the cigarette storage box under the pressure of the rejection mechanism.

[0011] This invention eliminates the need for a cigarette pushing device on one side of the cigarette conveying channel to push the cigarettes into the cigarette storage box. Instead, the cigarette storage box is placed below the cigarette conveying channel, and defective cigarettes are removed by pressing down with the rejection mechanism. This reduces the area occupied and lowers production costs. Attached Figure Description

[0018] This embodiment illustrates a tobacco strip removal device, such as... Figures 1-4 As shown, the system includes a cigarette conveying channel, a cigarette clamping and conveying mechanism, a rejection mechanism 2, and a cigarette storage box. The cigarette conveying channel (not shown in the figure) is fixedly installed on the frame 1, and the width of the cigarette conveying channel corresponds to the length of the cigarette pack 10. The cigarette conveying channel is existing technology and typically uses a support plate to support the cigarette pack 10, located below the cigarette clamping and conveying mechanism.

[0019] The cigarette clamping and conveying mechanism includes two cigarette clamping conveyor belts 3 respectively arranged on both sides of the cigarette conveying channel. The two cigarette clamping conveyor belts 3 clamp the two small end faces of the cigarette 10, so that the cigarette 10 moves with the cigarette clamping conveyor belts 3. The cigarette clamping and conveying mechanism drives the two cigarette clamping conveyor belts 3 to rotate simultaneously through a cigarette clamping drive motor fixed on the frame 1 via synchronous belt and synchronous pulley transmission, which can effectively maintain the synchronicity of the cigarette clamping transmission. This is existing technology and will not be described in detail.

[0020] The cigarette conveying channel has a perforated section located between the two cigarette conveying belts 3. The length of the perforated section is greater than the width of the cigarette 10, which facilitates the removal of defective cigarette 10. The cigarette storage box (not shown in the figure) is located below the perforated section and is used to store the removed defective cigarette 10.

[0021] The rejection mechanism 2 is located above the hollowed-out section and can move up and down. It has a downward-pressing rejection state and a normal conveying state located above the hollowed-out section. The rejection mechanism 2 is driven to move up and down by a rejection cylinder. When a defective cigarette strip 10 is detected, the rejection cylinder drives the rejection mechanism 2 to press down the cigarette strip 10, causing the defective cigarette strip 10 to enter the cigarette storage box. Then, the rejection mechanism 2 moves above the cigarette clamping conveyor belt 3, and the cigarette strip 10 resumes normal conveying.

[0022] Preferably, the frame 1 has movable support plates 5 installed on both sides of the hollow section. The movable support plates 5 are symmetrically arranged and are driven to move left and right by the support plate drive cylinder 4 to adjust the width of the hollow section. The movable support plates can be made very narrow, as long as they can support the cigarette packs during transmission, thus reducing the area occupied compared to the prior art.

[0023] When the rejection mechanism 2 is in the rejection state, the movable pallet 5 retracts away from the cigarette conveying channel, making the width of the hollow part greater than the length of the cigarette 10. This allows the cigarette 10 to break free from the clamping conveyor belt 3 under the pressure of gravity and the rejection mechanism 2 and enter the cigarette storage box. When the rejection mechanism 2 is in the normal transmission state, the movable pallet 5 extends, making the width of the hollow part less than the length of the cigarette 10. At this time, the movable pallet 5 supports the cigarette 10, and the cigarette 10 is normally transmitted under the clamping of the two clamping conveyor belts 3.

[0024] In this embodiment, both ends of the cigarette conveying channel are connected to the conveying channel of the cigarette inspection production line to complete the rejection of cigarettes 10. The method of detecting defective cigarettes is existing technology and can be referred to relevant patent literature.

[0025] This embodiment can also be improved in the following ways:

[0026] 1) The back of the cigarette-clamping conveyor belt 3 is provided with a tensioning device to tighten the cigarette-clamping conveyor belt 3. Preferably, such as Figures 2-4 As shown, the tensioning device is a brush 6, which can better hold the cigarette packs 10 after the cigarette conveyor belt 3 is tensioned; of course, the tensioning device can also be a spring sheet, etc.

[0027] 2) To facilitate the detection of defective cigarette pack 10, cigarette pack 10 will be removed, such as... Figure 4As shown, the frame 1 is equipped with a push plate 7 that can move left and right. The brush 6 or spring sheet is mounted on the push plate 7, which can be controlled by a cylinder. When the rejection mechanism 2 is in the smoke rejection state, the push plate 7 retracts, causing the brush 6 or spring sheet to move away from the smoke-clamping conveyor belt 3; when the rejection mechanism 2 is in the normal transmission state, the push plate 7 extends, causing the brush 6 or spring sheet to press against the smoke-clamping conveyor belt 3. To simplify the structure, as... Figure 4 As shown, the movable pallet 5 and the push plate 7 are integrated into one piece, and the left and right movement of the movable pallet 5 and the push plate 7 can be completed by a pallet-driven cylinder 4.
