Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, specifically to a tobacco shred feeder. Background Technology

[0002] In tobacco production, the tobacco feeder is a key piece of equipment that distributes tobacco from the pneumatic conveying pipes to various processing stations. Currently, all tobacco feeders use a single-sided feeding method, which has revealed a series of problems in practical applications. Firstly, single-sided feeding makes the production line layout relatively complex and inflexible. The arrangement of numerous feeding pipes not only increases planning difficulty but also leads to poor overall smoothness and coordination of the production line. Secondly, increasing the pipe length requires increasing the fan power. Furthermore, to meet the demands of large-scale production, multiple single-sided feeding feeders are needed, which undoubtedly significantly increases investment costs in equipment procurement, installation, and maintenance. To address these technical problems, this utility model provides a tobacco feeder. Utility Model Content

[0003] The purpose of this utility model is to provide a tobacco shred feeder that can effectively solve the problems of cumbersome production line layout and large production space occupation in existing tobacco shred feeders.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A tobacco feeder includes a feeder housing with at least two tobacco gas inlets at its upper part. A partition divides the interior of the feeder housing into at least two feeding zones, each corresponding to a tobacco gas inlet. From top to bottom, a return air screen, a cleaning roller assembly, and a cross gate assembly are arranged within the feeder housing. All three components penetrate the partition and rotate synchronously. An exhaust port is located on one side of the feeder housing, inside the return air screen. A tobacco outlet is located at the bottom of the feeder housing, corresponding to a feeding zone. The cross gate assembly is located at the tobacco outlet.

[0006] Furthermore, there are two tobacco gas inlets, two material feeding areas, and two tobacco outlets, with the tobacco gas inlets located on both sides of the material feeding device housing and staggered from each other.

[0007] Furthermore, the number of partitions is one, the outer contour of the partition is consistent with the inner contour of the feeder housing, and the partition is provided with mesh cylinder perforation, cleaning roller perforation and cross gate perforation.

[0008] Furthermore, the return air screen is provided with a frame assembly, which includes a central shaft, a first support plate and an airflow distribution ring. The central shaft is located at the center of the return air screen, and multiple first support plates are provided between the central shaft and the inner wall of the return air screen. An airflow distribution ring is provided between the included angles of two adjacent first support plates.

[0009] Furthermore, the sweeping roller assembly includes a sweeping roller shaft, a second support plate, a flexible sweeping strip, and a sweeping roller baffle. The sweeping roller baffle is located in the middle of the sweeping roller shaft and blocks the sweeping roller through-hole. Multiple second support plates are provided on the outer periphery of the sweeping roller shaft, and flexible sweeping strips are connected to the second support plates. The flexible sweeping strips are in contact with the bottom of the return air screen.

[0010] Furthermore, the cross door assembly includes a cross door central axis, a door panel, and a cross air baffle plate. The cross air baffle plate is located in the middle of the cross door central axis and blocks the cross door perforation. The door panel is disposed on the outer periphery of the cross door central axis.

[0011] Furthermore, a geared motor is provided on the outside of the feeder housing, and the output end of the geared motor is connected to the power transmission device. One end of the central shaft, the cleaning roller shaft, and the central shaft of the cross gate are all connected to the power transmission device.

[0012] Furthermore, a shaft connecting strip is provided on one side of the feeder housing, the shaft connecting strip is horizontally positioned at the exhaust hole, and the other end of the central shaft is rotatably mounted on the shaft connecting strip.

[0013] Compared with the prior art, the present invention can achieve at least the following beneficial effects:

[0014] 1. In traditional single-sided feeder applications, the feed pipe can only be accessed from one side, which often severely limits production line layout planning. This invention, however, incorporates an internal partition within the feeder housing. This partition divides the feeder's interior into two relatively independent feed areas, enabling simultaneous feeding from both sides. This allows for flexible selection of the feed pipe's access direction based on the production workshop's spatial structure, process flow, and development plans, thus enriching production line layout options. It eliminates the need for complex pipe turning, branching, and avoidance structures to accommodate single-sided feeding, making the connection between various stages simpler, more direct, and smoother.

[0015] 2. A return air screen is installed in the feeder housing and a frame is installed on the return air screen to achieve uniform distribution of airflow. This ensures that when feeding from both sides at the same time, the tobacco can fall smoothly in a stable airflow environment, thereby improving the uniformity and stability of the falling material. On the other hand, it can filter out the debris in the tobacco.

[0016] 3. A cleaning roller assembly is installed in the feeder housing to facilitate the removal of tobacco shreds clogged on the return air screen. A cross gate assembly is installed below the cleaning roller assembly to facilitate the orderly discharge of tobacco shreds. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] refer to Figures 1-2 As shown, this utility model provides a tobacco shred feeder, including a feeder housing 2. At least two tobacco gas inlets 1 are provided on the upper part of the feeder housing 2. The tobacco gas inlets 1 are connected to a pneumatic conveying pipe, thereby allowing the tobacco gas from the pneumatic conveying pipe to flow into and out of the feeder housing 2. A partition 9 is provided inside the feeder housing 2, dividing the interior of the feeder housing 2 into at least two feeding areas, corresponding to the tobacco gas inlets 1. From top to bottom, a return air mesh cylinder 3, a cleaning roller assembly 5, and a cross gate assembly 7 are arranged in the feeder housing 2. All three of the gate components 7 penetrate the partition 9 and are driven to rotate synchronously. The return air screen 3 can filter out debris and help improve the uniformity and stability of the material feeding. The cleaning roller assembly 5 can clean the tobacco shreds that are blocked on the return air screen 3. The cross gate assembly 7 can discharge the tobacco shreds in an orderly manner. The feeder housing 2 is provided with an exhaust hole 11 on one side, which is located inside the return air screen 3. Preferably, the exhaust hole 11 can be connected to the return air pipe to discharge debris and airflow. A tobacco shred outlet 8 is provided at the bottom of the feeder housing 2, which corresponds to the material feeding area. The cross gate assembly 7 is located at the tobacco shred outlet 8.

[0028] In this embodiment, the number of the tobacco gas inlet 1, the material feeding area, and the tobacco outlet 8 are all two, as shown in the reference. Figure 3 As shown, the tobacco gas inlet 1 is located on both sides of the feeder housing 2 and is staggered, so that both sides can be fed at the same time. This provides great flexibility for the arrangement of the tobacco feeding pipe and can greatly reduce the number of feeders used while meeting the actual needs of tobacco production.

[0029] In this embodiment, there is one partition 9, which is made of stainless steel and has a thickness of 4-8 mm. Its installation position is at the central axis of the feeder housing 2, evenly dividing the inner cavity into left and right regions. (Refer to...) Figure 4 As shown, the outer contour of the partition plate 9 is consistent with the inner contour of the feeder housing 2. The partition plate 9 is provided with a mesh tube through hole 91, a cleaning roller through hole 92 and a cross door through hole 93, so that the return air mesh tube 3, the cleaning roller assembly 5 and the cross door assembly 7 can be inserted into the above three holes.

[0030] The return air mesh cylinder 3 is equipped with a frame assembly 4, as shown in the reference. Figure 5 As shown, the frame assembly 4 includes a central shaft 41, a first support plate 43, and an airflow distribution ring 42. The central shaft 41 is located at the center of the return air mesh 3. Multiple first support plates 43 are arranged between the central shaft 41 and the inner wall of the return air mesh 3. An airflow distribution ring 42 is arranged between the included angles of two adjacent first support plates 43. Preferably, the airflow distribution ring 42 is made of Q235A steel plate, with a ring diameter of 400-500 mm and a ring length of 300-1200 mm. It is fixed to the frame of the first support plate 43 by welding.

[0031] In actual use, the tobacco airflow enters the feeder housing 2 and falls onto the return air screen 3, while the slag enters the return air screen 3. Due to the airflow and the exhaust port 11 on the side of the feeder housing 2, the slag-air mixture is discharged from the exhaust port 11, achieving material-air separation and slag removal. Furthermore, the first support plate 43 and the airflow distribution ring 42 facilitate uniform airflow distribution.

[0032] refer to Figure 6 As shown, the cleaning roller assembly 5 includes a cleaning roller shaft 51, a second support plate 52, a flexible cleaning strip 54, and a cleaning roller baffle plate 53. The cleaning roller baffle plate 53 is located in the middle of the cleaning roller shaft 51 and blocks the cleaning roller through hole 92, thereby preventing the airflow between the two chambers on both sides of the baffle plate 9 from flowing together. Multiple second support plates 52 are provided on the outer periphery of the cleaning roller shaft 51. Flexible cleaning strips 54 are connected to the second support plates 52. The flexible cleaning strips 54 are in contact with the bottom of the return air screen 3, thereby scraping off the tobacco shreds blocked on the return air screen 3.

[0033] refer to Figure 7 As shown, the cross door assembly 7 includes a cross door central shaft 71, a door panel 72, and a cross air baffle 73. The cross air baffle 73 is located in the middle of the cross door central shaft 71 and blocks the cross door perforation 93, thus preventing the airflow between the two chambers on both sides of the partition 9 from flowing together. The door panel 72 is arranged on the outer periphery of the cross door central shaft 71, and the rotation of the door panel 72 facilitates the orderly discharge of tobacco.

[0034] To enable the return air screen 3, the cleaning roller assembly 5, and the cross gate assembly 7 to rotate synchronously, a reduction motor 6 is provided on the outside of the feeder housing 2. The output end of the reduction motor 6 is connected to the power transmission device 10. The power transmission device 10 includes a cover, pulleys, and belts, etc. Its structure and connection relationship are existing technologies, and this utility model will not describe them further. One end of the central shaft 41, the cleaning roller shaft 51, and the central shaft 71 of the cross gate are all connected to the power transmission device 10, thereby realizing the synchronous drive of the three.

[0035] Since the exhaust port 11 is located at one end of the return air screen cylinder 3, in order to provide stable support for this end of the return air screen cylinder 3, a shaft connecting strip 12 is provided on one side of the feeder housing 2. The shaft connecting strip 12 is arranged laterally at the exhaust port 11, and the other end of the central shaft 41 is rotatably mounted on the shaft connecting strip 12.

[0036] The working process of this utility model is as follows: the tobacco airflow inlet 1 is connected to the pneumatic conveying pipe. The tobacco airflow from the pneumatic conveying pipe enters the feeder housing 2 through the tobacco airflow inlet 1 and first falls onto the return air screen cylinder 3. The slag enters the return air screen cylinder 3 through the filter holes and is discharged from the exhaust hole 11 under the action of the airflow, thereby achieving the purpose of material-gas separation and slag removal. Since the return air screen cylinder 3 and the frame assembly 4 are rotating, the tobacco airflow will be evenly distributed on the return air screen cylinder 3 and fall from one side of the return air screen cylinder 3 onto the cross gate assembly 7. The cross gate assembly 7 evenly discharges tobacco during rotation. On the other hand, during this process, the tobacco will block the filter holes of the return air screen cylinder 3. The cleaning roller assembly 5 can scrape off the blocking material by contacting the bottom of the return air screen cylinder 3.

[0037] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that those skilled in the art can devise many other modifications and implementations that fall within the scope and spirit of the principles disclosed herein. More specifically, various modifications and improvements can be made to the components or layout of the subject matter arrangement within the scope of the disclosure, drawings, and claims. Besides modifications and improvements to the components or layout, other uses will be apparent to those skilled in the art.
