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 the tobacco shred production line, the tobacco sheet loosening and rehumidification machine is very important, which can loosen the raw tobacco blocks, increase the moisture content and temperature of the raw tobacco blocks, and improve the processing resistance and sensory quality. However, due to the large size of the raw materials and their easy adhesion, especially the high-grade formula tobacco leaves, the loosening and rehumidification effect is directly affected.

[0003] like Figure 2 As shown, the slitting device used for the 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 vertically through the frame, and the cigarette fork is driven up and down by the cylinder to cut the tobacco block twice. When the larger tobacco block is cut into sheet-shaped tobacco blocks by the slicer, the cigarette fork moves up and down in equal time, piercing the passing tobacco block to create an easy break point 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 rehumidification machine, 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 rehumidification machine. Due to the existence of the easy breaking point 200, the tobacco blocks will be separated to achieve homogenized production. However, when the tobacco fork moves up and down, it is easy to entrain tobacco blocks. After multiple forks, the materials 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 rehumidification machine and material breakage. Summary of the invention

[0005] The present disclosure provides a cigarette block cutting device to solve the above technical problems.

[0006] A tobacco block cutting device, the tobacco block cutting device comprises an adjusting screw mounted on two frames, each of the adjusting screws is connected to a corresponding mounting frame; the mounting frame on the right side is fixedly mounted with a right side bearing seat, and the mounting frame on the left side is fixedly mounted with a left side bearing seat; it also comprises a motor assembly for providing power to a rotating roller; the rotating roller comprises a rotating roller body, a rotating shaft, and a cutter mounting plate; the left end of the rotating shaft is connected to the left side bearing seat, and is connected to the motor assembly through a key, and the right end of the rotating shaft is connected to the right side bearing seat; a cutter for cutting tobacco blocks is fixed on the cutter mounting plate; four cutter mounting plates are evenly arranged along the circumferential direction of the rotating roller body.

[0007] 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.

[0008] In some embodiments, three cutter mounting holes are formed on the cutter mounting plate, and the cutter fixing bolts pass through the cutter mounting holes and the bolt through holes formed on the cutter to fix the cutter on the cutter mounting plate.

[0009] 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.

[0012] In some embodiments, the cutter mounting hole, the rotating roller body, the rotating shaft, and the cutter mounting plate are an integrated structure.

[0013] The beneficial effects of the present invention are as follows: first, the tangential direction of the 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 cigarette blocks, thus avoiding the cigarette blocks from clogging and slipping on the conveyor belt.

[0014] Secondly, 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.

[0015] Third, the cutter only leaves a small incision on the tobacco block, which eventually breaks naturally at the entrance of the loosening and rehumidification machine due to gravity, reducing the breakage of the tobacco leaves. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] like Figure 1As shown, the tobacco block cutting device includes an adjusting screw 6 installed on two frames 7, and each of the adjusting screws is connected to a mounting frame; the right mounting frame is fixedly installed with a right bearing seat 4, and the left mounting frame is fixedly installed with a left bearing seat; it also includes a motor assembly 5 for providing power to the rotating roller 1; the rotating roller includes a rotating roller body, a rotating shaft, and a cutter mounting plate 11; the left end of the rotating shaft is connected to the left bearing seat, and is connected to the motor assembly through a key, and the right end of the rotating shaft is connected to the right bearing seat; a cutter 2 for cutting tobacco blocks is fixed on the cutter mounting plate; four cutter mounting plates are evenly arranged along the circumferential direction of the rotating roller body.

[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 formed on the cutter mounting plate, and the cutter fixing bolts 3 pass through the cutter mounting holes and the bolt through holes formed 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, so that the left end of the rotating shaft is connected to 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, so that the right end of the rotating shaft is connected to 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 collecting 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 the frame are connected by an adjusting screw. The height of the rotating roller can be adjusted by adjusting the screw and the fixing nut to match the changed slicer parameters. The frame is a fixed part with a fixing hole at the bottom, which is fixed to the ground by 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 accordingly after cutting, some materials may leak to the ground. Therefore, this embodiment also provides a corresponding material receiving plate 8 to receive the leaked material for easy recycling.

[0051] Installation of this slitting device: fix the frame to the ground with anchor bolts, place the 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 cooperate with the corresponding bearings arranged 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, decelerated by the reducer, drives the rotating roller to rotate, and the cutter rotates accordingly, cutting a certain depth of easy-to-break belt from the tobacco block below. The easy-to-break belt 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 rehumidification machine. Under the action of their own weight, the front tobacco block begins to separate from the rear tobacco block from the easy-to-break belt and enters the drum of the loosening and rehumidification 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 embodiments 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, thus avoiding the tobacco blocks from getting stuck 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, which is finally broken naturally at the entrance of the loosening and rehumidification machine by gravity, thereby reducing the breakage of the tobacco leaves.
