Description

Technical Field

[0001] This invention relates to the field of tobacco equipment technology, and in particular to a tobacco shred buffer cabinet cloth device. Background Technology

[0002] On a tobacco processing production line, in order to ensure continuous production and stable material supply for subsequent processes after the shredding process, and because the shredding machine's production capacity is greater than that of the subsequent processes, a small buffer cabinet is installed after shredding to buffer the produced tobacco shreds.

[0003] Existing buffer cabinets employ a stacking feeding method, starting material distribution from the outlet and proceeding backwards, with the overall operating mode being simultaneous inflow and outflow. In actual production, the material is stacked along the central axis of the buffer cabinet, resulting in uneven distribution of tobacco material within the cabinet, with a higher concentration in the middle and lower concentrations on both sides. This leads to low material storage efficiency in the buffer cabinet. Furthermore, the uneven distribution causes fluctuations in the outlet flow rate of the buffer cabinet, affecting the flow stability of subsequent processes and impacting process quality.

[0004] Therefore, there is an urgent need for a tobacco shredding cabinet fabric device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a tobacco shreds buffer cabinet feeding device that can make the tobacco shreds in the tobacco shreds buffer cabinet body evenly distributed, ensure tobacco shreds storage efficiency, reduce the fluctuation of the discharge flow of the tobacco shreds buffer cabinet body, and ensure the flow stability of subsequent processes.

[0035] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figure 1 and Figure 2As shown, this embodiment provides a tobacco shreds buffer cabinet feeding device, including a feeding cart 100, a diffuse reflection photoelectric switch group 200, a feeding assembly 300, and a main control device. The feeding cart 100 is located above the tobacco shreds buffer cabinet body 1 and can move along the length direction of the tobacco shreds buffer cabinet body 1. The diffuse reflection photoelectric switch group 200 is located at the bottom of the feeding cart 100 and is configured to measure the height of tobacco shreds in the width direction inside the tobacco shreds buffer cabinet body 1. The feeding assembly 300 includes a guide trough 301, which is rotatably located at the material outlet of the feeding cart 100. The main control device is electrically connected to the diffuse reflection photoelectric switch group 200 and the driving device of the feeding cart 100. When the diffuse reflection photoelectric switch group 200 measures the height of tobacco shreds in the width direction inside the tobacco shreds buffer cabinet body 1 to reach a preset height, the feeding cart 100 moves a preset distance along the length direction of the tobacco shreds buffer cabinet body 1.

[0037] In this embodiment, the tobacco shredding cabinet feeding device, when the diffuse reflection photoelectric switch group 200 does not measure that the tobacco shreds have reached the preset height, the feeding cart 100 is fixed above the tobacco shredding cabinet body 1 and feeds the tobacco shreds downwards. The tobacco shreds enter the tobacco shredding cabinet body 1 through the guide trough 301. When the diffuse reflection photoelectric switch group 200 measures that the tobacco shreds at that position have reached the preset height, the guide trough 301 is rotated, and the guide trough 301 feeds the tobacco shreds to the position in the width direction of the tobacco shredding cabinet body 1 where the tobacco shreds have not reached the preset height. This action is repeated until the tobacco shreds in the width direction of the tobacco shredding cabinet body 1 all reach the preset height. Then, the feeding cart 100 moves a preset distance along the length direction of the tobacco shredding cabinet body 1 and is fixed at that position. The above operation is repeated until the tobacco shreds in the width direction of the tobacco shredding cabinet body 1 at that position all reach the preset height. The tobacco shreds distribution device in the tobacco shreds buffer cabinet can ensure that the tobacco shreds are evenly distributed in the tobacco shreds buffer cabinet body 1, thus ensuring the tobacco shreds storage efficiency. Moreover, the even distribution of tobacco shreds can reduce the fluctuation of the discharge flow rate of the tobacco shreds buffer cabinet body 1, thus ensuring the flow rate stability of subsequent processes.

[0038] For example, a guide rail 11 is provided above the tobacco shreds buffer cabinet body 1 along the length direction, and the fabric trolley 100 is set on the guide rail 11. The guide rail 11 can ensure the movement path of the fabric trolley 100 and prevent the fabric trolley 100 from deviating and detaching from the tobacco shreds buffer cabinet body 1 during movement.

[0039] In some specific embodiments, the diffuse reflection photoelectric switch group 200 includes a diffuse reflection photoelectric switch 201 in zone I, a diffuse reflection photoelectric switch 202 in zone II, and a diffuse reflection photoelectric switch 203 in zone III. The diffuse reflection photoelectric switch 201 in zone I, the diffuse reflection photoelectric switch 202 in zone II, and the diffuse reflection photoelectric switch 203 in zone III are electrically connected to the main control device. The fabric cart 100 is divided into three regions on an average basis along the width direction of the tobacco buffer cabinet body 1. The three regions are zone I, zone II, and zone III, respectively. The diffuse reflection photoelectric switch 201 in zone I is located at the center point of zone I, the diffuse reflection photoelectric switch 202 in zone II is located at the center point of zone II, and the diffuse reflection photoelectric switch 203 in zone III is located at the center point of zone III. By using diffuse reflection photoelectric switches 201 (zone I), 202 (zone II), and 203 (zone III) located at the center points of zones I, II, and III respectively, the feeding height of the tobacco shreds in each zone can be controlled. That is, when the tobacco shred material height in a given feeding zone reaches a preset height, the guide chute 301 rotates to feed the next feeding zone. After all three zones simultaneously meet the preset tobacco shred material height requirement, the feeding cart 100 moves a preset distance along the length of the tobacco shred buffer cabinet body 1, feeding the tobacco shreds into the three zones along the width direction at that location, and repeating this cycle. For example, the feeding cart 100 has a width of L, divided into three zones, each 1 / 3L. The center point of each zone is the specific location of the diffuse reflection photoelectric switch for that zone. The function of each zone's diffuse reflection photoelectric switch is to measure the tobacco shred material height in its respective zone.

[0040] Optionally, the fabric assembly 300 also includes a steering component 302, which is mounted on the fabric carriage 100. The steering component 302 is electrically connected to the main control device, and its output end is connected to the guide trough 301. The steering component 302 is configured to drive the guide trough 301 to rotate, and controls the rotation angle of the guide trough 301 through a guide component, thereby automating the rotation of the guide trough 301. A connecting shaft 303 is provided at the output end of the steering component 302, and the end of the connecting shaft 303 away from the steering component 302 is connected to the guide trough 301.

[0041] A support frame 101 is provided on the fabric carriage 100, and a steering component 302 is mounted on the support frame 101. The support frame 101 supports the steering component 302 to ensure its stability. In a specific embodiment, a slide rail is provided on the support frame 101, and the steering component 302 is slidably mounted on the slide rail of the support frame 101, so that the position of the steering component 302 can be adjusted to reduce dead angles in the tobacco feeding. Exemplarily, the steering component 302 can be, but is not limited to, a servo motor.

[0042] Considering that materials such as tobacco shreds have low density and large gaps when fed, and that the tobacco shreds may sink or collapse over time, resulting in a decrease in the height of the first batch of materials fed, in some specific embodiments the tobacco shreds buffer cabinet feeding device also includes a distance measuring component 400. The distance measuring component 400 is installed on the tobacco shreds buffer cabinet body 1 and is electrically connected to the main control device. The distance measuring component 400 is configured to measure the distance that the feeding cart 100 moves along the length direction of the tobacco shreds buffer cabinet body 1. The ranging component 400 calculates and detects the current feeding area position, simulating the tobacco shreds buffer cabinet body 1 area as an xy coordinate system. The x-axis direction is the direction of diffuse reflection photoelectric switch 201 in area I, diffuse reflection photoelectric switch 202 in area II, and diffuse reflection photoelectric switch 203 in area III. The y-axis direction is the feeding direction of the material distribution trolley 100. According to the actual situation of the tobacco shreds buffer cabinet body 1, a fixed moving distance of the material distribution trolley 100 is set to form the coordinates of the fixed detection point position. After all the material is fed, the material distribution trolley 100 moves at a constant speed from the material head position to the material tail position of the tobacco shreds buffer cabinet body 1. During the operation, the height information of the tobacco material at the pre-set detection point position is stored in the data block of the main control device. After all the detection is completed, the material distribution trolley 100 sequentially feeds the position where the height has not reached the preset height to fill the height and solve the problem of tobacco sinking and collapsing over time.

[0043] For example, the ranging component 400 includes a laser ranging transmitter 401 and a reflector 402. The laser ranging transmitter 401 is disposed on the tobacco buffer cabinet body 1 and is electrically connected to the main control device. The reflector 402 is disposed on the material feeding cart 100. The laser ranging transmitter 401 measures the real-time position of the material feeding cart 100.

[0044] In some specific embodiments, the inlet cross-sectional area of ​​the guide trough 301 is larger than the outlet cross-sectional area, so that the inlet of the guide trough 301 can accommodate the tobacco material transported out of the material outlet of the material distribution trolley 100, and the outlet of the guide trough 301 can collect the tobacco material that has passed through the guide trough 301. The guide trough 301 has an inclined structure, and the inlet height of the guide trough 301 is higher than the outlet height, so that the tobacco material can fall smoothly from the outlet of the guide trough 301 under the action of gravity.

[0045] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
