Description

Technical Field

[0001] The present invention relates to the recovery of discarded cigarettes, in particular to a waste cigarette processing flow control device for a waste cigarette processing machine and cigarette recovery equipment using the device. Background Art

[0002] Waste cigarette processing machine is a device used by cigarette industry enterprises to recycle tobacco from unqualified and defective cigarettes. The above-mentioned waste cigarette processing process includes the process of sorting cigarettes, also known as sorting. Sorting is to send the disorderly waste cigarettes horizontally and vertically to the linear vibrating screen with corrugated plates as the sorting screen surface by quantitative feeding belt conveyor, and comb the cigarettes in one direction under the action of the guide plate on the corrugated plate.

[0003] Waste cigarette processing machines can be divided into cutting type, creasing type and blowing type according to different tobacco separation methods. The waste cigarette processing machine is an important pre-processing device of the waste cigarette processing machine, which is related to the tobacco recovery rate of subsequent equipment.

[0004] The traditional way of sorting cigarettes is to rely on a quantitative feeding belt conveyor or a quantitative vibrating screen to send the waste cigarettes to the corrugated plate working surface of the linear vibrating screen used for sorting. The working surface is provided with grooves matching the diameter of the cigarettes, and several guide plates protruding from the surface of the corrugated plate. The sorted cigarettes are sorted in the grooves until they are transported to the tobacco separation equipment. In order to prevent the waste cigarettes from overlapping on the corrugated plate screen surface, that is, the cigarettes are stacked together, it is necessary to control the flow of the cigarettes to prevent the stacked cigarettes from entering the next process. Since the traditional corrugated plate exists as the screen frame of the vibrating screen, it is not easy to install a flow limiting plate at the corrugation. Even if the fixed flow limiting plate can limit the height to allow only materials with the same height as a cigarette to pass through, the cigarettes will inevitably be blocked at the flow limiting plate and make it difficult for subsequent cigarettes to pass through, resulting in reduced efficiency in cigarette sorting. Therefore, in the above case, the traditional flow limiting method reduces the number of cigarettes when feeding, and controls the number of cigarettes reaching the corrugated plate through a quantitative feeding belt conveyor, thereby achieving flow control.

[0005] The above solution solves the problem of cigarette flow control to a certain extent. However, since the above solution controls the feed at the source, it is difficult to control the quantitative feeding belt conveyor to an appropriate amount, so that the corrugated plate is in a high-efficiency working state. Usually, the utilization rate of cigarettes in the grooves of the corrugated plate is less than %, which causes the corrugated plate and subsequent tobacco separation equipment to be in an ineffective working period of at least % of the time. In view of this situation, it is necessary to improve the tobacco sorting equipment to improve its working efficiency. Summary of the invention

[0006] In view of the above problems, the purpose of the present invention is to propose a flow control device for a waste cigarette processing machine to solve the technical problem of low working efficiency of the vibrating screen caused by flow control during waste cigarette sorting.

[0007] The technical solution is to include a rotating shaft and a fixed frame, wherein the rotating shaft is rotatably installed on the fixed frame and forms a structure that spans above the corrugated plate, and the rotating shaft is driven by a power source to form a controlled rotating structure, and a plurality of toggling members corresponding to the grooves on the upper end surface of the corrugated plate are arranged on the rotating shaft, and each of the toggling members rotates with the rotating shaft to realize the toggling of the cigarette along the direction of each of the grooves, and the distance between the lowest point of each toggling member and the lowest point of the groove forms a height that only allows one cigarette to pass through, and an auxiliary guide plate fixed at the groove interval of the corrugated plate is arranged axially between each of the toggling members, and one end of the auxiliary guide plate is fixed at the groove interval, and the other end extends to between the two toggling members.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0024] In the description of the present invention, “plurality” means two or more than two, unless otherwise clearly and specifically defined.

[0025] A cigarette recovery device comprises a cigarette feeder 100, a vibrating screen 200 with a corrugated plate 403, and a tobacco separation device 300, and is characterized in that it also comprises a tobacco sorting and flow control device 400 fixed above the corrugated plate 403.

[0026] The cigarette loader 100 includes an inclined main body, including a conveyor belt 101, a baffle plate 104 located at the upper end surface of the conveyor belt 101, a feed hopper 102 located below, and a distribution hopper 103 above. Driven by the loader motor, the conveyor belt 101 transports the waste cigarettes in the hopper to the distribution hopper 103 through the action of the baffle plate 104 and drops them onto the vibrating screen 200 with a corrugated plate 403.

[0027] The vibrating screen 200 includes a frame 205 and a first screen frame 201 located below the material distribution hopper 103. The screen surface of the first screen frame 201 is a corrugated plate 403. The corrugated plate 403 is a plate-like structure. The upper end surface of the corrugated plate 403 is provided with an array of concave grooves 403.1. The shape of the grooves 403.1 matches the cigarette. The corrugated plate 403 is vibrated so that the cigarette is transported along the direction of the grooves 403.1. The grooves 403.1 are compactly arranged and spaced apart. A vertical guide plate is provided at the space. The guide plate is used to assist in the arrangement of the cigarettes during vibration so that the cigarettes fall into the grooves 403.1, thereby completing the process of sorting the cigarettes. The outer frame of the first screen frame 201 is connected to the end of the elastic support 202. The other end of the elastic support 202 is connected to the frame. The screen frame is driven to vibrate by a vibration motor. The vibration motor is fixedly installed at the first screen frame 201, forming a structure in which the first screen frame 201 is driven by the vibration motor.

[0028] Of course, in some embodiments, the vibrating screen 200 is a multi-stage screen, and a second screen frame 203 is further arranged below the first screen frame 201. The elastic support 202 is a bent structure, including three connection points at the upper, lower and middle positions. The first screen frame 201 and the second screen frame 203 are respectively connected to the upper and lower ends of the elastic support 202, forming a structure in which the first screen frame 201 and the second screen frame 203 are linked by the elastic support 202. The middle connection point of the elastic support 202 is connected to a fixed frame 204 located between the first screen frame 201 and the second screen frame 203, and the fixed frame 204 is fixedly connected to the frame. The end of the second screen frame 203 is connected to the output end of the vibration motor through a connecting arm, forming a structure in which the vibration motor directly drives the second screen frame 203 and then drives the first screen frame 201 to vibrate.

[0029] The waste cigarette processing machine uses a flow control device, including a rotating shaft 401 and a fixed frame 402. The rotating shaft 401 is rotatably mounted on the fixed frame 402 and forms a structure that spans above the corrugated plate 403. The fixed frame 402 includes a crossbeam 402.1 and columns 402.2 located at both ends of the crossbeam 402.1. The two columns 402.2 are fixedly connected to the crossbeam 402.1, and of course, they can also be detachably fixedly connected. The two columns 402.2 and the crossbeam 402.1 form a gantry-like structure that spans above the corrugated plate 403. The rotating shaft 401 is provided with a lifting mechanism to form a structure in which the interval between the toggle member 404 and the groove 403.1 is adjustable. The column 402.2 includes a base and a vertical frame. A U-shaped notch is provided at the vertical frame. A sliding seat 402.4 is slidably fitted in the U-shaped notch. A bearing assembly for mounting the rotating shaft 401 is provided at the sliding seat 402.4. In the above or some embodiments, the lifting mechanism includes a lifting motor 402.3 and a ball screw pair / threaded screw pair 402.3 located above both ends of the rotating shaft 401. The screw / screw of the ball screw pair / threaded screw pair 402.3 is transmission-connected to the lifting motor 402.3, and the nut of the ball screw pair / threaded screw pair 402.3 is fixedly connected to the sliding seat 402.4; one end of the rotating shaft 401 is transmission-connected to a driving motor 405, and the driving motor 405 is fixedly mounted on the outer end surface of the sliding seat 402.4.

[0030] A toggle member 404 and a corrugated plate 403, wherein a plurality of toggle members 404 corresponding to the grooves 403.1 on the upper end surface of the corrugated plate 403 are arranged on the rotating shaft 401, and each of the toggle members 404 rotates with the rotating shaft 401 to realize toggling of the cigarette along the direction of its groove 403.1, and the distance between the lowest point of each toggle member 404 and the lowest point of the groove 403.1 forms a height that only allows one cigarette to pass through, and an auxiliary guide plate 403.2 fixed at the interval of the grooves 403.1 of the corrugated plate 403 is arranged axially between each of the toggle members 404, and one end of the auxiliary guide plate 403.2 is fixed at the interval of the grooves 403.1, and the other end extends to between the two toggle members 404.

[0031] In the above or some embodiments, the linear velocity direction of the lowest point of the toggle member 404 is opposite to the cigarette conveying direction at the corrugated plate 403. When the directions are opposite, the end of the cigarette first contacts the toggle member 404. Since the cigarette is light in weight and the toggle member 404 has a high velocity, the cigarette bounces under the impact of the toggle member 404, and is hit by the toggle member 404 in the lower left area and bounces again to other areas of the corrugated plate 403, so that the cigarettes can be sorted again.

[0032] In the above or some embodiments, the linear velocity direction of the lowest point of the toggle member 404 is the same as the cigarette conveying direction at the corrugated plate 403, and the linear velocity of the lowest point of the toggle member 404 is 10 times or more the cigarette conveying speed at the corrugated plate 403. At this time, the toggle member 404 plays the role of striking and toggling the gathered cigarettes in the conveying direction to realize the redistribution of the cigarettes.

[0033] In the above or some embodiments, the toggle member 404 is a disc-shaped structure with a toggle tooth 404.1. When it is a disc-shaped structure, the toggle member 404 passes through the middle through the through hole and the rotating shaft 401. The toggle member 404 and the rotating shaft 401 can be connected to each other through a key connection. Of course, the distance between each toggle member 404 can be controlled by inserting a sleeve to control the distance between the toggle members 404.

[0034] In the above or some embodiments, the toggle member 404 is a structure with a rod-shaped toggle rod, and the toggle member 404 includes a plurality of circumferentially arranged toggle rods and one end is directly or indirectly fixed to the rotating shaft 401. When it is a rod-shaped structure, the toggle rods are evenly distributed on the outer circumference of the rotating shaft 401, and the toggle rods can be welded and fixed to the rotating shaft 401. Of course, the toggle rods can be fixed on a base plate of a cylindrical structure, and the base plate is fixedly connected or keyed to the rotating shaft 401.

[0035] This solution is different from the previous cigarette flow control equipment. Its flow control acts directly on the corrugated plate 403, and through the action of the toggle member 404, the cigarettes stacked at the flow limiting position are dispersed to other positions of the corrugated plate 403 to obtain opportunities for re-sorting and sorting, thereby greatly improving the utilization efficiency of the corrugated plate 403, thereby improving the recovery efficiency of the waste cigarette recovery equipment.
