Description

Technical Field

[0001] The present application relates to the technical field of tobacco leaf processing, and in particular to an online leaf structure sampling device. Background Art

[0002] In the process of tobacco leaf processing, the tobacco factory needs to use a leaf thresher to thresh the tobacco leaves. The leaf thresher is equipped with leaf threshers. After the tobacco leaves are fed into the leaf thresher, they are repeatedly hit and torn by the leaf threshers in the leaf thresher, so that the leaves and stems of the tobacco leaves are separated, and the leaves are broken to a certain extent. The broken leaves are discharged from the discharge port of the leaf thresher and fall down on the conveyor belt. The leaves are transported to the next process via the conveyor belt for subsequent processing. The broken leaf structure needs to be sampled and tested to ensure that the size of the leaf structure meets the production standards. The current sampling method is: the operator directly holds a certain amount of leaves on the conveyor belt. Pieces are then placed at a designated location for inspection of blade size. This sampling method has certain drawbacks. After the crushed blades fall onto the conveyor belt, due to the effect of gravity and the different sizes of the blades, the blades are roughly stacked in layers on the conveyor belt, with larger blades on the top layer, middle-sized blades in the middle layer, and smaller blades at the bottom layer. That is, the smaller the size of the blade, the lower the layer will be. When manually holding the blades, it is not possible to evenly hold blades of various sizes distributed in layers. The subsequent test results cannot truly reflect the actual size of the blades, affecting the accuracy of the test results. Utility Model Content

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] like Figure 1-Figure 10As shown, the embodiment of the present application provides an online leaf structure sampling device, which is applied to a tobacco leaf processing line. In the past, when processing tobacco leaves, the tobacco leaves had to be processed by a leaf beater. After being processed by the leaf beater, the leaves and stems of the tobacco leaves were separated from each other, and the leaves were broken to a certain extent. The broken leaves were discharged from the discharge of the leaf beater and fell onto a conveying device such as a conveyor belt. The leaves were transported to a subsequent process for processing via the conveyor device. The leaves broken by the leaf beater need to be sampled and tested regularly to detect whether the size specifications of the leaves meet the standards. When sampling, the operator directly picks up a certain amount of leaves at a conveying device such as a conveyor belt, and then places the picked leaves at a detection point for subsequent testing. This sampling method has certain disadvantages. The shredded blades are of different sizes. After the blades are discharged from the leaf beater and fall onto a conveying device such as a conveyor belt, the blades will be stacked on the conveying device. The smaller the blades, the lower they will sink, and the larger the blades, the closer they will be to the top. Therefore, when the operator holds the blades, he cannot hold the layered blades evenly, which makes the subsequent detection results inaccurate. The detection results are not sufficient to reflect the size of the blade structure after the leaf beater has processed it, so it will affect the accuracy of the blade structure detection. The present application aims to provide a device that can evenly extract the blade structure after the leaf beater has processed it, so as to achieve even extraction, so that the subsequent detection results are more objective and accurate, and can accurately reflect the actual size of the blade after the leaf beater has processed it, thereby improving the accuracy of detection and ensuring production quality.

[0031] Specifically, the online leaf structure sampling device includes a frame 1, and a yield window 101 is provided on the frame 1. Actually in a workshop, the frame 1 is arranged between a leaf beater and a conveying device. The conveying device can be a conveying belt, etc., for conveying tobacco leaves processed by the leaf beater. The tobacco leaves processed by the leaf beater are sent out from the discharge end of the leaf beater and fall downward onto the conveying device. The frame 1 is arranged in the falling path of the leaves. When the leaves fall, the leaves can pass through the yield window 101 on the frame 1 and fall. The frame 1 also includes a hopper 2 and a driving assembly 3. The hopper 2 is movably arranged on the frame 1, and the driving assembly 3 is arranged between the hopper 2 and the frame 1. The driving assembly 3 is used to drive the hopper 2 to move back and forth on the frame 1, so that the hopper 2 can move back and forth between a first position and a second position. When the hopper 2 moves to the first position, the hopper 2 can intercept the falling leaves and receive the falling leaves. When the hopper 2 When moving to the second position, the hopper 2 no longer intercepts the falling blades, so that the blades can fall down through the window on the frame 1 onto the conveying device, so that the blades are conveyed to the subsequent process for processing via the conveying device. Preferably, the frame 1 can be in the form of a frame. In the vertical direction, a vacant setting in the middle of the frame structure forms a makeshift window 101 of the frame 1. In the vertical direction, the vacant setting in the middle of the frame structure can be closed or partially open. In one example, the frame 1 includes four vertically arranged support legs 11, and the four support legs 11 correspond to the four corners of a rectangle. Along the enclosing direction of the rectangle, a cross arm is arranged between the tops of two adjacent support legs 11, so that the vacant setting in the middle in the vertical direction forms the makeshift window 101 of the frame 1, and under the action of the support legs 11, it can also be conveniently straddled above the conveying device, which is convenient for the layout of the equipment, and the hopper 2 can be movably arranged on the cross arm.

[0032] In the present embodiment, when the tobacco leaves processed by the thresher are discharged outward from the discharge end of the thresher and fall, the distribution of leaves of different sizes is uniform, the falling leaves are intercepted as a whole by the hopper 2, and the falling leaves are collected in the hopper 2 to realize sampling of the leaves, and the size distribution of the sampled leaves is uniform. The leaves intercepted and collected in the hopper 2 can fully and truly reflect the structural size distribution of the leaves after being processed by the thresher, and the subsequent detection structure is more accurate, which is conducive to improving the accuracy of the detection and avoiding tobacco production quality problems caused by inaccurate detection.

[0033] In this embodiment, the hopper 2 is arranged in the shape of a long trough, and the top of the hopper 2 is arranged as an opening. A discharge port 21 is arranged at one end of the hopper 2 along the length direction of the hopper 2. After the hopper 2 moves to the first position to receive the leaves, the leaves received inside can be discharged outward through the discharge hopper 2 at the end, and then the discharged leaves with uniform size distribution are transferred to the detection point for detection. In practice, the flow cross-section of the leaves sent out by the discharge end of the tobacco leaf beater has a certain length in the horizontal direction, so that the hopper 2 is arranged in a form with a length, which is more conducive to the precise interception and collection of the leaves, and prevents the leaves in some local positions from escaping from the collection range of the hopper 2 and falling down onto the conveying device. It should be noted that after collecting the leaves, the hopper 2 moves to the second position, and then the collected tobacco leaves can be discharged by manually shifting to the discharge port 21, and can be collected by a lightweight plastic handheld container and transferred to the detection point for subsequent detection.

[0034] Preferably, a conveyor belt 3 can be provided inside the hopper 2, and the conveying direction of the conveyor belt 3 is provided along the length direction of the hopper 2, the width direction of the conveyor belt 3 is equivalent to the internal width of the hopper 2, and the top of the conveyor belt 3 is provided at a height lower than the top height of the hopper 2, that is, the two side walls of the hopper 2 along the length direction play a role of blocking materials on both sides of the conveying direction of the conveyor belt 3, and then when the hopper 2 collects the falling leaves, the leaves fall downward on the conveyor belt 3, and after the collection is completed, the conveyor belt 3 can transport the collected leaves to the discharge port 21 at the end for external discharge, thereby making it more convenient for the leaves to be discharged from the hopper 2. For this, the hopper 2 can be provided with openings at both the top and the bottom, and the conveyor belt 3 is arranged inside the hopper 2 along the length of the hopper 2. In the vertical projection, the outermost end of one end of the hopper 2 can extend out of the range of the frame 1, and the inner part of this end of the hopper 2 , the length extension range of the conveyor belt 3 is smaller than the internal length extension range of the hopper 2. At this point, the gap formed between the end of the conveyor belt 3 and the interior of the hopper 2 constitutes the discharge port 21 of the hopper 2, and then the conveyor belt 3 can transport the collected blades to this point and let them fall down. Then they can be collected by other handheld containers and transferred to the detection point for detection. In addition, for the other end of the conveyor belt 3, it can be equivalent to the internal extension length of the other end of the hopper 2, but it should not affect the normal operation of the conveyor belt 3. The other end of the conveyor belt 3 can also be smaller than the internal extension length of the other end of the hopper 2, but the cross-sectional length range in the horizontal direction when the blade falls is smaller than the length of the conveyor belt 3, and the falling range of the blade is within the length range of the conveyor belt 3, so that the blade can fall accurately on the conveyor belt 3 to prevent the blade from falling on the outside of the conveyor belt 3.

[0035] In the present embodiment, both end portions of the hopper 2 along the length direction can be slidably arranged on the frame 1. Preferably, the two ends of the hopper 2 mentioned here can be slidably arranged on the frame 1, and can be a local preset position close to the outermost end of the hopper 2, which is convenient for equipment layout. The moving direction of the hopper 2 between the first position and the second position is perpendicular to the length direction of the hopper 2. In the present embodiment, the length of the fluid cross-section formed by the falling blades in the horizontal direction is parallel to the length direction of the hopper 2, and thus, the distance between the first position and the second position can be appropriately reduced, so that the hopper 2 can move within a small range to intercept or release the blades, and the drive component 3 consumes less energy.

[0036] Preferably, for the rectangle enclosed by the multiple cross arms of the frame 1, the positions near the two ends of the hopper 2 can be slidably arranged on two opposite cross arms respectively. It can be that multiple sliders 41 are arranged at one end of the hopper 2, and a slide rail 42 is arranged on the frame 1. The direction of the slide rail 42 is arranged horizontally. The slide rail 42 is specifically arranged on the cross arm at one end, and the direction of the slide rail 42 and the length direction of the hopper 2 are arranged perpendicular to each other. The slider 41 cooperates with the slide rail 42, and the slider 41 can slide and move along the direction of the slide rail 42. The multiple sliders 41 The sliders 41 and the slide rails 42 are arranged at intervals so that the cooperation of the sliders 41 and the slide rails 42 can limit the movement of the hopper 2, so that the hopper 2 moves straight on the frame 1, and prevents the hopper 2 from tilting in the horizontal direction during the movement. A pulley 51 is provided at the other end of the hopper 2, and a slideway 52 is provided on the frame 1. The direction of the slideway 52 is horizontal, and the direction of the slideway 52 and the length direction of the hopper 2 are perpendicular to each other. The slideway 52 is preferably a cross arm at the other end of the hopper 2, and the pulley 51 slides directly on the cross arm at this end.

[0037] In one example, the hopper 2 is horizontally arranged in the length direction, and in the vertical direction, the pulley 51 and the slider 41 are respectively arranged on different sides of the hopper 2, or in other words, in the vertical direction, the pulley 51 is located in the top direction of the hopper 2, and the slider 41 is located in the bottom direction of the hopper 2. In this way, the force application points of the frame 1 as a whole on the hopper 2 as a whole are respectively located above and below the hopper 2 in the vertical direction, which is beneficial for the hopper 2 to maintain balance and stability, avoid tipping over of the hopper 2, and improve the stability of the equipment operation.

[0038] In this embodiment, the height of the slide 52 is higher than the hopper 2, that is, along the length direction of the hopper 2, the cross arms at both ends of the frame 1 are set at different heights, the cross arm at one end is below the hopper 2, and the height of the cross arm at the other end is higher than the height of the hopper 2. The cross arm at the higher position constitutes the slide 52, and a connecting arm 53 is provided on the hopper 2 at one end corresponding to the slide 52, and the pulley 51 is provided on the connecting arm 53. The hopper 2 is slidably suspended on the slide 52 through the connecting arm 53 and the pulley 51. In this embodiment, In the example, the bottom end of the connecting arm 53 is connected to the hopper 2, and the other end of the connecting arm 53 forms a horizontal bend so that it can cooperate with the pulley 51 to be slidably suspended on the slide 52. It is preferred to provide multiple connecting arms 53, which is more conducive to maintaining the balance and stability of the hopper 2. In this embodiment, for the cross arm at a higher position at this end, an extension section 12 can be provided at this end of the frame 1, and the extension section 12 is extended upward. There are two extension sections 12, and the two ends of the slide 52 are respectively connected to the top of the two extension sections 12.

[0039] The driving component 3 can be a cylinder, which is arranged on the frame 1. The output end of the cylinder is connected to the hopper 2. Under the drive of the cylinder, the hopper 2 can be reciprocated between the first position and the second position. A support column 6 can be arranged on the crossbeam on which the slide rail 42 is arranged, and the cylinder is installed on the support column 6. A connecting plate 7 is arranged at the bottom of the hopper 2, and the output end of the cylinder is connected to the connecting plate 7 to realize the driving of the hopper 2.

[0040] Preferably, a support plate 8 is provided at the bottom of one end of the corresponding slide rail 42 of the hopper 2, and two support plates 8 are provided. The two support plates 8 are located on both sides of the length direction of the hopper 2 at this end of the hopper 2, and the slider 41 is provided at the bottom of the support plate 8. The support plate 8 plays the role of raising the hopper 2 on the frame 1 as a whole to a certain height for the installation of the cylinder. In this embodiment, the connecting plate 7 can be provided adjacent to the support plate 8 on one side, and the connecting plate 7 and the adjacent support plate 8 can be an integrated structure. Compared with the method of providing the connecting plate 7 for connecting with the output end of the cylinder, the extension lengths of the support plates 8 on both sides can also be different. Specifically, the support plates 8 on both sides extend to the other end of the hopper 2 along the length direction of the hopper 2 at different lengths, so that in the direction perpendicular to the length of the hopper 2, the parts of the support plates 8 on both sides close to the other end of the hopper 2 are mutually offset, which is convenient for connection with the output end of the cylinder. After the cylinder is provided on the support column 6, the axial direction of the cylinder is perpendicular to the length direction of the hopper 2, so as to apply a force parallel to the moving direction to the hopper 2.

[0041] The working principle of the present application is as follows: in the process of processing tobacco leaves, after the thresher has processed the tobacco leaves, the tobacco leaves are sent out from the discharging end of the thresher and fall down onto the conveying device through the giving way window 101 of the frame 1. The leaves are transferred to other processes via the conveying device for subsequent processing. When it is necessary to sample and test the tobacco leaves processed by the thresher, the cylinder drives the hopper 2 to move to the first position so that the hopper 2 intercepts the falling leaves, and then the leaves fall onto the conveyor belt 3 in the hopper 2. After receiving a sufficient amount of leaves, the cylinder drives the hopper 2 to return to the second position to stop intercepting the leaves, so that the leaves can resume normal processing. The yield window 101 on the frame 1 falls downward onto the conveying device, so the interception and collection of leaves by the hopper 2 will not affect the normal operation of the tobacco processing line, and online sampling is achieved. Then the conveyor belt 3 in the hopper 2 is started, so that the conveyor belt 3 moves the collected leaves to the discharge port 21 of the hopper 2. The discharged leaves can be collected at the discharge port 21 of the hopper 2 by a handheld container and transferred to the detection point for detection. The handheld container can be a square box or a bucket, etc. In this way, sampling of the leaf structure discharged by the leaf beater can be achieved uniformly, so that the size distribution of the collected leaves is more uniform and the detection result is more accurate.
