Description

Technical Field

[0001] This utility model belongs to the technical field of tobacco vibration sorting screen supporting facilities, specifically an automatic tobacco material spreading system based on a vibration sorting screen. Background Technology

[0002] With the development of the tobacco industry, the variety of cigarettes has become increasingly diversified, with new categories such as medium, short, and thin cigarettes constantly emerging and their market share increasing year by year. Consumers have increasingly higher requirements for product quality, among which the whole tobacco rate and broken tobacco rate are particularly important to the quality of cigarettes. Therefore, it is essential to determine the whole tobacco rate and broken tobacco rate of the materials during the tobacco raw material production process. According to the standard "YC / T 178-2003 Method for Determination of Whole Tobacco Rate and Broken Tobacco Rate", the method uses a vibrating sorting screen to separate the tobacco into four sizes using three different sizes of screens. The weight of the tobacco shreds sieved from each layer of screen is weighed, and the whole tobacco rate and broken tobacco rate of the tobacco material are calculated using a formula.

[0003] Traditional vibrating sorting screens require manual sampling, weighing, and spreading of materials on the production line for determining the whole tobacco shred rate, broken tobacco shred rate, or tobacco sheet size. Manual spreading is time-consuming and labor-intensive, and the uneven distribution of materials has a significant impact on the experimental results, resulting in poor data consistency and low detection efficiency. Utility Model Content

[0004] The purpose of this utility model is to design an automatic tobacco material spreading system based on a vibrating sorting screen, which is based on the above-mentioned existing technology. This automatic spreading system can greatly improve work efficiency and the accuracy of detection data.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] An automatic tobacco material spreading system based on a vibrating sorting screen includes a lifting and feeding unit and a vibrating uniform spreading unit. After the lifting and feeding unit verifies the weight of the material, it is conveyed to the vibrating uniform spreading unit, which then evenly feeds it into the vibrating sorting screen.

[0007] The lifting and feeding unit includes a support frame, a vertical linear drive module, a cantilever support frame, a horizontal linear drive module, a weighing module, and a conveyor belt. The vertical linear drive module is fixedly installed on the support frame. The cantilever support frame is fixedly installed on the vertical linear drive module and can be driven to move up and down by it. The horizontal linear drive module is installed on the cantilever support frame. The conveyor belt is set on the horizontal linear drive module through the weighing module and can move left and right with the horizontal linear drive module.

[0008] The vibrating uniform material spreading unit includes a fixed base plate, a support seat, an elastic plate, a crank connecting rod mechanism, a motor, a hopper, and a sensor. The hopper is set on the fixed base plate through the support seat, the elastic plate, and the crank connecting rod mechanism, and the motor drives the crank connecting rod mechanism to vibrate and feed the material into the sorting screen. The sensor is set on the outer frame of the sorting screen through a bracket to detect the thickness and uniformity of the material sprinkled in the sorting screen in real time.

[0009] Furthermore, the elastic plate is a spring plate or an elastic manganese steel plate. The vertical linear drive module and the horizontal linear drive module can be driven by a motor or by a pneumatic source.

[0010] Furthermore, the sensor is a laser infrared sensor, which monitors in real time the height of the material conveyed by the vibrating uniform feeding unit falling into the vibrating sorting screen. The feeder inside the vibrating sorting screen will only move after a certain height is reached; otherwise, it will continue to wait for the material to accumulate to the specified height.

[0011] The lifting and feeding unit and the vibrating and uniform spreading unit are set separately. The former is located near the feeding end of the sorting screen, and the latter is located above the feeding end of the sorting screen. The conveyor belt in the lifting and feeding unit moves to the top of the spreading unit under the drive of the vertical and horizontal linear drive modules and overlaps with the spreading unit for a certain distance before unloading into the hopper of the spreading unit.

[0012] The working process of this utility model is as follows: The tester pours the material taken from the production line onto the conveyor belt of the lifting and feeding unit. After the lifting and feeding unit verifies the weight of the material, it lifts it to a designated height, that is, moves it to the height above the vibrating uniform spreading unit and then drives the conveyor belt carrying the tobacco material to move until it is directly above the vibrating uniform spreading unit and overlaps with it by a certain distance. The conveyor belt starts and slowly drops the material into the hopper of the vibrating uniform spreading unit below (the front baffle is a certain height away from the belt, and the gap can be used for material to be dropped); the vibrating uniform spreading unit can evenly spread the material falling into the hopper into the vibrating sorting screen below through high-frequency low-radius vibration. Through the vibrating sorting screen and the detection sensor, the height of the spread material is detected and controlled in real time to achieve the effect of evenly spreading the material.

[0013] The advantages of this utility model are as follows: This automatic tobacco material spreading system replaces the complex manual operation procedures such as sampling, weighing and spreading on the production line that are required in the existing technology. It overcomes the defects of manual spreading, such as being time-consuming and labor-intensive, unevenly spreading materials, having a significant impact on the measurement of experimental results and poor data consistency. It realizes automatic spreading of materials in the process of measuring the whole filament rate and broken filament rate of tobacco raw materials, thereby improving work efficiency and the accuracy of test data.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figure 1-9 As shown: An automatic tobacco material spreading system based on a vibrating sorting screen includes a lifting and feeding unit 1 and a vibrating uniform spreading unit 2. After the lifting and feeding unit verifies the weight of the material, it is conveyed to the vibrating uniform spreading unit, which then evenly feeds it into the vibrating sorting screen 3.

[0026] The lifting and feeding unit 1 includes a support frame 1.1, a vertical linear drive module 1.2, a cantilever support frame 1.3, a horizontal linear drive module 1.4, a weighing module 1.5, and a conveyor belt 1.6. The vertical linear drive module 1.2 is fixedly installed on the support frame 1.1. The cantilever support frame 1.3 is fixedly installed on the vertical linear drive module 1.2 and can be driven to move up and down by it. The horizontal linear drive module 1.4 is installed on the cantilever support frame 1.3. The conveyor belt 1.6 is set on the horizontal linear drive module 1.4 through the weighing module 1.5 and can move left and right with the horizontal linear drive module.

[0027] The vibrating uniform material spreading unit 2 includes a fixed base plate 2.1, a support base 2.2, an elastic plate 2.3, a crank-connecting rod mechanism 2.4, a motor 2.5, a hopper 2.6, and a sensor 2.7. The hopper 2.6 is mounted on the fixed base plate 2.1 via the support base 2.2, the elastic plate 2.3, and the crank-connecting rod mechanism 2.4. The motor 2.5 drives the crank-connecting rod mechanism 2.4 to vibrate and feed material from the hopper 2.6 into the sorting screen 3. The sensor 2.7 is mounted on the outer frame of the sorting screen via a bracket 2.8 to detect the thickness and uniformity of the material falling into the sorting screen in real time.

[0028] Furthermore, the elastic plate is a spring plate or an elastic manganese steel plate. The vertical linear drive module and the horizontal linear drive module can be driven by a motor or by a pneumatic source.

[0029] The lifting and feeding unit 1 and the vibrating and uniform spreading unit 2 are set separately. The former is located near the feeding end of the sorting screen, and the latter is located above the feeding end of the sorting screen. The conveyor belt 1.6 in the lifting and feeding unit moves to the top of the spreading unit and overlaps with it for a distance before unloading into the hopper 2.6 of the spreading unit.

[0030] A more detailed explanation is as follows:

[0031] The testers simply pour the material taken from the production line onto the conveyor belt 1.6 of the lifting and feeding unit 1. After the weighing module 1.5 verifies the weight of the material, the lifting and feeding unit 1 lifts it to a designated height, that is, moves it to the height above the vibrating and uniformly spreading unit 2, and then drives the conveyor belt 1.6 carrying the tobacco material to move until it is directly above the vibrating and uniformly spreading unit 2, overlapping it by a certain distance (see...). Figure 5 Once the conveyor belt is started, the material will slowly fall into the hopper 2.6 of the vibrating uniform spreading unit 2 below. The vibrating uniform spreading unit can spread the material falling into the hopper evenly into the vibrating sorting screen 3 below through high-frequency low-radius vibration. The vibrating sorting screen 3 and the detection sensor 2.7 work together to detect and control the height of the spread material in real time to achieve the effect of uniformly spreading the material.

[0032] The vertical linear drive module 1.2 can drive the cantilever support frame 1.3 and the components installed above it to move up and down. The horizontal linear drive module 1.4 is fixedly installed on the cantilever support frame 1.3. The horizontal linear drive module 1.4 can move the conveyor belt 1.6 and the weighing module 1.5 above it left and right. The weighing module 1.5 can weigh the original material mass and weigh the material mass in the laying state in real time, accurately control the quality of the laid material and improve the laying uniformity.

[0033] In the vibrating uniform material spreading unit, the support base 2.2, one end of the crank-connecting rod mechanism 2.4, and the motor 2.5 are all fixedly installed on the fixed base plate 2.1. The other end of the crank-connecting rod mechanism is fixedly installed below the bottom plate of the hopper 2.6. The support bases 2.2 are connected and supported by elastic plates 2.3. That is, the hopper 2.6 is supported by the support bases 2.2 and elastic plates 2.3, and the motor 2.5 drives the crank-connecting rod mechanism 2.4 to cause the hopper 2.6 to vibrate. The material on the hopper will jump forward evenly until it is evenly sprinkled into the vibrating sorting screen below. The height of the material sprinkled into the vibrating sorting screen is detected in real time by the sensor 2.7, and the running speed of the feeding belt of the vibrating sorting screen is adjusted to achieve uniform spreading of tobacco material in the vibrating sorting screen 3.
