Description

Technical Field

[0001] This invention relates to the field of conveying and proportioning devices, specifically to a multi-channel proportioning device and method for blending tobacco components. Background Technology

[0002] Tobacco shreds refer to tobacco products made by cutting tobacco leaves into shreds, granules, flakes, powder, or other shapes, adding auxiliary materials, fermenting and storing them, and selling them for smoking without rolling them.

[0003] Different components of tobacco (such as main tobacco, expanded tobacco, and sheet tobacco) are usually transported to a blending drum by different conveyors for mixing. In the existing conveying and blending process, multiple conveyors are usually used to transport the tobacco separately. One component of tobacco is first transported to a dynamic scale for weighing, and then another component of tobacco is transported, weighed, and then poured into the blending drum for mixing. If only one scale is used, when one conveyor is in operation, the other conveyor needs to be stopped, which increases the number of control steps. Using multiple scales will increase the floor space and the number of inspection steps. Therefore, the existing blending method has many steps and low efficiency. At the same time, multiple conveyors occupy a lot of space, which affects the movement of workers and the handling of materials. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-channel proportioning device and method for blending tobacco components to overcome the above-mentioned shortcomings in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-channel proportioning device for blending tobacco components, comprising a first conveyor and a second conveyor, and further comprising: a batching chamber; a first baffle plate and a second baffle plate, both of which are rotatably installed in the batching chamber and are connected by a transmission belt; a dynamic scale, which is disposed below the batching chamber and the batching chamber is disposed on the dynamic scale; the first baffle plate and the second baffle plate each have a receiving position, and the first baffle plate and the second baffle plate are arranged at staggered angles at their respective receiving positions so that the receiving time of the first baffle plate and the second baffle plate is staggered.

[0006] Preferably, the first and second conveyors are fixedly equipped with material distribution plates, and the material distribution plates are inclined.

[0007] Preferably, a reflux plate is fixedly installed at the end of the material distribution plate away from the material dispensing cavity.

[0008] Preferably, the top of the material distribution plate is provided with an arc-shaped end, and a sliding plate is slidably installed on the arc-shaped end. A protruding rod is slidably installed on the sliding plate. The protruding rod slides along the radial direction of the sliding plate. An abutment groove is opened on the protruding rod. An abutment rod is fixedly installed on the material distribution plate.

[0009] Preferably, the surface of the first resistive plate is provided with grooves.

[0010] Preferably, a protruding plate is fixedly installed on the slide plate, and a spring is fixedly installed between the protruding plate and the material distribution plate.

[0011] Preferably, the skateboard has a chamfer.

[0012] Preferably, a bearing arc plate is fixedly installed on the first resistive plate.

[0013] Preferably, a first baffle and a second baffle are also included;

[0014] The first baffle is located between the first and second material blocking plates to prevent material on the first material blocking plate from falling onto the second material blocking plate.

[0015] A method for blending tobacco components in a multi-channel ratio includes the following steps:

[0016] S1. The first and second conveyors are arranged in an overlapping manner to save floor space;

[0017] S2, the first conveyor and the second conveyor transport materials, which fall alternately onto the first and second blocking plates;

[0018] S3. The first material blocking plate collects one batch of material. At this time, the first material blocking plate will rotate to drive the second material blocking plate to rotate and collect another batch.

[0019] S4. The second material blocking plate collects the material of another component until the total weight reaches the predetermined requirement. Then, the first and second material blocking plates stop collecting and the material is discharged for blending.

[0020] In the above technical solution, the present invention provides a multi-channel proportioning device and method for blending tobacco components, which has the following beneficial effects: In this application, the conveyors are stacked to reduce their floor space. At the same time, during the conveying process, the stacked conveyors can pre-select one component of tobacco by using the cooperation of the first and second blocking plates and a dynamic scale. Then, the second blocking plate is used to select another component of tobacco. After the blending ratio is met, the first and second blocking plates simultaneously discharge the material, and pre-mixing is carried out at the same time as the material is discharged, thereby improving the blending efficiency and reducing the floor space and operation steps.

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] Please see Figure 1-7 A multi-channel proportioning device and method for blending tobacco components, comprising a first conveyor 1 and a second conveyor 2, and further comprising:

[0033] Ingredient dispensing chamber 3;

[0034] The first material blocking plate 51 and the second material blocking plate 52 are both rotatably installed in the dispensing cavity 3, and are connected by a transmission belt 54.

[0035] The dynamic scale is located below the batching chamber 3, and the batching chamber 3 is located on the dynamic scale.

[0036] The first material blocking plate 51 and the second material blocking plate 52 each have a material receiving position, and the first material blocking plate 51 and the second material blocking plate 52 are arranged at staggered angles when they are in their respective material receiving positions so that the material receiving time of the first material blocking plate 51 and the second material blocking plate 52 is staggered.

[0037] Among them, reference Figure 2 When the first blocking plate 51 is placed horizontally, the second blocking plate 52 is positioned to the lower left. At this time, the first conveyor 1 and the second conveyor 2 transport materials normally. The belt 41 on the first conveyor 1 transports the material to the first blocking plate 51. Because the second blocking plate 52 is positioned to the lower left, there is a gap between the second blocking plate 52 and the second conveyor 2, preventing the material from falling onto the second blocking plate 52. The first blocking plate 51 collects the material separately. Simultaneously, since the dispensing chamber 3 is located on a dynamic scale, the scale displays the weight of the material on the first blocking plate 51 in real time. Once the required weight is reached, for example, x1, the servo motor starts, driving the first blocking plate 51 to rotate clockwise. This causes the first blocking plate 51 to rotate to the upper right, separating it from the belt 41 on the first conveyor 1. At this point, the material on the first conveyor 1 will not fall onto the first blocking plate 51. Because the first blocking plate 51 is positioned to the lower left, the material on the second conveyor 2 will not fall onto the first blocking plate 51. The first and second blocking plates 51 are connected by a transmission belt 54. A servo motor is also fixedly installed in the mixing chamber 3. The output end of the servo motor is fixedly connected to the center of the first blocking plate 51. When the first blocking plate 51 rotates, it will synchronously drive the second blocking plate 52 to rotate. The second blocking plate 52 will then rotate to a horizontal position. At this time, the material on the second conveyor 2 will fall onto the second blocking plate 52. The dynamic weighing weight will continue to increase until it reaches x2. Then the servo motor will start again, driving the first and second blocking plates 51 and 52 to rotate clockwise. At the same time, the second blocking plate 52 will also avoid the material on the second conveyor 2. The material will not contact the first and second blocking plates 51 and 52, and the weight of the material on both will not change. Therefore, when the first and second blocking plates 51 and 52 rotate clockwise, the pre-mixed material can be poured into the mixing drum below for thorough mixing.

[0038] In another embodiment of the present invention: a material distribution plate 61 is fixedly installed on the first conveyor 1 and the second conveyor 2, and the material distribution plate 61 is inclined.

[0039] The material distribution plate 61 is inclined to the lower left. When the first material blocking plate 51 separates from the first conveyor 1, and the second material blocking plate 52 separates from the second conveyor 2, the tobacco material conveyed by the belt 41 on the first conveyor 1 and the second conveyor 2 will fall directly downwards. The fallen tobacco material will land on the material distribution plate 61 and slide downwards along the material distribution plate 61.

[0040] In another embodiment of the present invention: a return plate 61.1 is fixedly installed at the end of the dispensing plate 61 away from the dispensing cavity 3;

[0041] The return plate 61.1 is semi-circular, and several blocks 42 are fixedly installed on the belt 41. When the tobacco slides to the bottom with the distribution plate 61, the blocks 42 on the belt 41 will drive the tobacco at the bottom of the distribution plate 61 to continue to be conveyed. The return plate 61.1 allows the tobacco to rise with the belt 41, so as to cooperate with manual or mechanical feeding to convey and mix.

[0042] In another embodiment of the present invention: the top end of the material distribution plate 61 is provided with an arc-shaped end, and a slide plate 62 is slidably installed on the arc-shaped end. A protruding rod 64 is slidably installed on the slide plate 62. The protruding rod 64 slides along the radial direction of the slide plate 62. An abutment groove 65 is provided on the protruding rod 64. An abutment rod 68 is fixedly installed on the material distribution plate 61.

[0043] The material distribution plate 61, located below the first material blocking plate 51, has an arc-shaped end. When the first material blocking plate 51 rotates clockwise until the material on it falls, the first material blocking plate 51 will contact the protruding rod 64 on the sliding plate 62. At this time, the first material blocking plate 51 will drive the protruding rod 64 to move, and the protruding rod 64 will drive the sliding plate 62 to move. The sliding plate 62 will then retract towards the arc-shaped end of the material distribution plate 61, thereby preventing the protruding part from affecting the material falling from the first material blocking plate 51. At the same time, the first material blocking plate 51 and the material distribution plate 61... The arc-shaped end and the arc-shaped surface of the slide plate 62 are in contact, so that when the first blocking plate 51 rotates, some tobacco located on the arc-shaped end of the distributing plate 61 and the surface of the slide plate 62 can be pushed away and slide down along the inclined end of the distributing plate 61. At the same time, when the abutting groove 65 on the protruding rod 64 contacts the abutting rod 68, the abutting rod 68 will first squeeze the inclined side of the abutting groove 65, so that the protruding rod 64 slides down until the protruding rod 64 separates from the first blocking plate 51. At this time, the first blocking plate 51 will continue to move without being hindered.

[0044] The upper end of the inclined side is located at the tip of the arc end, which can divide the tobacco falling from the first conveyor 1 into two parts. One part slides down to the arc end, and the other part slides down along the inclined side of the dividing plate 61.

[0045] In another embodiment of the present invention: a groove 53 is formed on the surface of the first resist plate 51;

[0046] When the first baffle plate 51 rotates clockwise to contact the arc-shaped end of the separating plate 61 and the sliding plate 62, some tobacco shreds that have fallen from the first conveyor 1 will be on the arc-shaped end of the separating plate 61 and the sliding plate 62. At this time, the first baffle plate 51 not only acts as a scraper when it rotates clockwise, but also collects some tobacco shreds in conjunction with the groove 53.

[0047] Among them, reference Figure 3 At this point, the first and second blocking plates 51 and 52 are in their initial receiving positions. The first blocking plate 51 is horizontal, while the second blocking plate 52 is tilted to the lower left. The top centers of both the first and second blocking plates 51 and 52 are slightly concave inward to allow the material to slide towards the center as it falls, preventing accumulation at one end. As the first conveyor 1 and the second conveyor 2 move, the tobacco from the first conveyor 1 falls onto the first blocking plate 51, while the second blocking plate 52 does not accept the tobacco from the second conveyor 2 until the dynamic scale reaches a weight of x1. At this point, the servo motor rotates, causing the first blocking plate 51 to rotate. Simultaneously, the first blocking plate 51 drives the second blocking plate 52 to rotate. This continues until the second blocking plate 52 rotates to a horizontal position, at which point the first blocking plate 51 tilts upward, separating from the first conveyor 1. 2. The material is received, and the material on the first conveyor 1 slides to the left through the distribution plate 61, while some remains at the arc end of the distribution plate 61. When the dynamic scale reaches x2, the servo motor rotates again. At this time, the clockwise rotation of the first blocking plate 51 will abut against the protrusion 64, which will cause a change in the value of the dynamic scale. However, since the batching is completed at this time, it does not need to be considered. As the tobacco on the first blocking plate 51 falls, the raw materials on the second blocking plate 52 will also fall, so that the tobacco of different components can be pre-blended. The groove 53 set on the first blocking plate 51 allows the first blocking plate 51 to receive some raw materials when it passes the arc end of the distribution plate 61. At this time, the value of the dynamic scale returns to the initial value due to the falling of the material on the first blocking plate 51 and the second blocking plate 52. However, the raw materials carried on the first blocking plate 51 are still less than x1, so the rotation of the first servo motor will not be triggered.

[0048] In another embodiment of the present invention: a protruding plate 63 is fixedly installed on the slide plate 62, and a spring 67 is fixedly installed between the protruding plate 63 and the material distribution plate 61;

[0049] When the first resisting plate 51 moves the slide plate 62 inward, the spring 67 will be compressed until the first resisting plate 51 is removed from the protrusion 64. At this time, the spring 67 will push the slide plate 62 to reset.

[0050] In another embodiment of the present invention: a chamfer 66 is provided on the sliding plate 62;

[0051] The material distribution plate 61 is provided with a clearance groove 69, and the material inside the slide plate 62 can be squeezed out by the chamfer 66 when it slides.

[0052] In another embodiment of the present invention: a bearing arc plate 55 is fixedly installed on the first resisting plate 51;

[0053] When the first supporting plate rotates to an upward tilt, the second blocking plate 52 rotates to a horizontal position. The supporting arc plate 55 prevents the material on the first blocking plate 51 from slipping off when it is tilted, thus maintaining the accuracy of the values. At the same time, when the second blocking plate 52 receives the material and rotates, the first blocking plate 51 rotates again, causing the material blocked by the supporting arc plate 55 to slip off. At the same time, the material on the second blocking plate 52 will also slip off. At this time, both raw materials will fall, and in the air, the raw materials will disperse, thus allowing the two raw materials to be pre-mixed in the air.

[0054] When the first baffle plate 51 rotates to an inclined position, the material on it accumulates towards the bearing arc plate 55. The bearing arc plate 55 causes the relatively dispersed tobacco material to be piled up. At this time, the tobacco material on the first baffle plate 51 forms clumps. When the first baffle plate 51 rotates to drop the material, the clumps of tobacco fall off relatively quickly, while the tobacco on the second baffle plate 52 is more dispersed. At this time, the tobacco on the first baffle plate 51 is easier to catch up with and mix into the tobacco on the second baffle plate 52, thus premixing.

[0055] In another embodiment of the present invention, a first baffle 71 and a second baffle 72 are also included.

[0056] The first baffle 71 is located between the first material blocking plate 51 and the second material blocking plate 52 to prevent the material on the first material blocking plate 51 from falling onto the second material blocking plate 52.

[0057] Both the first baffle 71 and the second baffle 72 can be installed in the batching chamber 3 by a bracket without being directly connected to the batching chamber 3. When the material on the first baffle 51 falls, the top of the first baffle 71 is located below the slide plate 62. At this time, the raw material on the first baffle 51 will slide down the inner wall of the batching chamber 3 through the first baffle 71. At the same time, as the raw material on the second baffle 52 falls, the two will mix and fall onto the second baffle 72, and then fall into the mixing drum through the second baffle 72 for further mixing.

[0058] A method for blending tobacco components in a multi-channel ratio includes the following steps:

[0059] S1. The first conveyor 1 and the second conveyor 2 are arranged in an overlapping manner to save floor space;

[0060] S2, the first conveyor 1 and the second conveyor 2 transport materials, which fall alternately onto the first baffle plate 51 and the second baffle plate 52;

[0061] S3. The first material blocking plate 51 collects a group of materials. At this time, the first material blocking plate 51 will rotate to drive the second material blocking plate 52 to rotate and collect another group.

[0062] S4. The second material blocking plate 52 collects the material of another component until the total weight reaches the predetermined requirement. Then, the first material blocking plate 51 and the second material blocking plate 52 stop collecting and drop the material for blending.

[0063] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
