Description

Technical Field

[0001] The present invention belongs to the technical field of cigarette manufacturing, and in particular relates to a cigarette block cutting device. Background Art

[0002] In tobacco shred production lines, tobacco sheet loosening and rehumidification machines are crucial. They loosen the raw tobacco blocks, increase their moisture content and temperature, and improve their workability and sensory quality. However, the large size and tendency of the raw tobacco leaves to stick together, especially for high-quality blends, directly impact the loosening and rehumidification effect.

[0003] like Figure 2 As shown, the slitting device used for loose rehydration of the vacuum rehydration line is a cigarette fork 100 perpendicular to the conveyor belt. The characteristics of the cigarette fork slitting device are: the cigarette fork is fixed above the conveyor belt perpendicularly by a frame, and the cigarette fork is driven up and down by a cylinder to cut the tobacco blocks twice. After the larger tobacco blocks are cut into slices by the slicer, the cigarette fork moves up and down in equal time, piercing the tobacco blocks passing by, creating easy-to-break points 200, such as Figure 3 shown.

[0004] like Figure 4 As shown, when the tobacco blocks move in the direction of arrow A and arrow B and enter the entrance of the loose rehumidifier, where the direction of arrow A represents the flow direction of the electronic scale and the direction of arrow B represents the entrance direction of the loose rehumidifier, the tobacco blocks will be separated due to the existence of the easy-to-break point 200 to achieve homogenized production. However, when the tobacco separating fork moves up and down, it is easy to entrain tobacco blocks. After multiple forks, the material will be blocked on the belt, further causing the tobacco blocks to slip on the conveyor belt, which will lead to insufficient tobacco leaves supplied to the rehumidifier and material breakage.

[0041] In some embodiments, the circumference of the rotating roller body is equal to 1 / 4 of the length of the tobacco block to be cut.

[0042] In some embodiments, three cutter mounting holes 111 are provided on the cutter mounting plate, and the cutter fixing bolts 3 pass through the cutter mounting holes and the bolt through holes provided on the cutter to fix the cutter on the cutter mounting plate.

[0043] In some embodiments, the right mounting frame is provided with a first screw through hole, and the right bearing seat is provided with a second screw through hole. The adjusting screw on the right side passes through the first screw through hole and the second screw through hole at one time, and the right bearing seat is fixedly installed on the right mounting frame by a fixing nut.

[0044] In some embodiments, a left bearing is provided on the left bearing seat, and the left end of the rotating shaft is connected to the left bearing, thereby realizing the connection between the left end of the rotating shaft and the left bearing seat.

[0045] In some embodiments, a right bearing is provided on the right bearing seat, and the right end of the rotating shaft is connected to the right bearing, thereby realizing the connection between the right end of the rotating shaft and the right bearing seat.

[0046] In some embodiments, the cutter mounting hole, the rotating roller body, the rotating shaft, and the cutter mounting plate are an integrated structure.

[0047] The rotating roller rotates three times, creating three easy-to-break zones on the tobacco block, dividing the tobacco block into four equal parts.

[0048] The motor assembly includes a motor, a fan, a junction box, a reducer, an oil collection box, etc. The motor is controlled by a frequency converter and has a fixed ratio with the movement speed of the belt conveyor, which can divide the smoke block into four parts.

[0049] The bearing seat and frame are connected by an adjusting screw. By adjusting the screw and fixing nut, the height of the rotating roller can be adjusted to match the changed slicer parameters. The frame is a fixed part with fixing holes at the bottom and is fixed to the ground with anchor bolts.

[0050] In order to install the cigarette block cutting device, it is necessary to cut the surface blocking plates 9 on both sides of the belt conveyor. Since two avoidance holes 10 are formed after cutting, some materials may leak to the ground. Therefore, this embodiment also provides a corresponding receiving plate 8 to receive the leaked materials for easy recycling.

[0051] Installation of this slitting device: fix the frame to the ground with anchor bolts, place the material receiving plate at the dripping position of the leaked material, use the adjusting screw and the fixing nut to connect the left mounting frame and the left bearing seat, at the same time, fix the motor assembly to the left mounting frame with bolts, and the two ends of the rotating roller match the corresponding bearings provided on the corresponding bearing seats, and the motor assembly is connected to the left end of the rotating roller through a key.

[0052] Use of this slitting device: When the equipment is running, the belt conveyor transports the tobacco blocks cut by the slicer to the bottom of the rotating roller at a certain speed. Under the action of the frequency converter, the motor rotates at a fixed ratio speed, is decelerated by the reducer, drives the rotating roller to rotate, and the cutter rotates accordingly, cutting a certain depth of easy-to-break zone from the tobacco block below. The easy-to-break zone is divided into four parts. Under the action of the belt conveyor, the pre-treated tobacco blocks pass through the electronic scale and are ready to enter the loosening and rehumidifying machine. Under the action of their own weight, the front tobacco blocks begin to separate from the rear tobacco blocks at the easy-to-break zone and enter the drum of the loosening and rehumidifying machine to complete the processing.

[0053] When the belt conveyor stops moving, the cigarette block cutting device stops running at the same time.

[0054] In the embodiment of the present disclosure, the tangential direction of movement of the rotating roller is consistent with the running direction of the conveyor belt, and at the same time it is not easy to entrain tobacco blocks, thereby preventing tobacco blocks from clogging and slipping on the conveyor belt; the height of the rotating roller can be adjusted by adjusting the screw to match the changes in the parameters of the front-end slicer, that is, it can cope with different types of tobacco blocks; the cutter only leaves a smaller incision on the tobacco block, and finally uses gravity to naturally break it at the entrance of the loosening and rehumidification machine, reducing the breakage of tobacco leaves.
