Description

Technical Field

[0001] The invention relates to the technical field of flue-cured tobacco leaf curing equipment, and in particular to a high-rise tobacco rack structure of a tobacco leaf curing room. Background Art

[0002] The curing of flue-cured tobacco is different from that of sun-dried tobacco. It mainly uses the hot air inside the curing room to remove moisture from fresh tobacco leaves and transform the chemical components inside the tobacco leaves. In order to ensure the curing quantity of tobacco leaves, the existing curing room sets up multiple grills from top to bottom to achieve the hanging and curing of 3-4 sheds of tobacco leaves at the same time. That is, after the fresh tobacco leaves in the prior art are braided (the carrier is the tobacco rod) or clamped (the carrier is the tobacco clamp), the two ends of the carrier are hung on two grills at the same height, so that 3-4 layers of tobacco leaves are hung from top to bottom. This requires the staff to move from the inside of the curing room to the outside and repeatedly climb up to achieve the hanging of high-rise tobacco leaves. In addition, the internal space of the curing room is narrow and cramped, and the overall operation is very cumbersome. At the same time, the spacing between the tobacco leaves cannot be evenly arranged, resulting in poor fluidity of the hot air flow in the later stage, which in turn affects the heating and dehumidification effects of the tobacco leaves. Summary of the invention

[0003] The object of the present invention is to provide a high-rise tobacco rack structure for a tobacco curing room. The present invention has a simple structure and can effectively realize the equidistant arrangement of tobacco carriers in the curing room. At the same time, the loading and unloading operations of tobacco carriers in the curing room can be carried out at the door of the curing room, and the operating space is larger.

The driving block located at the end of the inner direction of the baking room is fixedly provided with a threaded sleeve for screwing the lead screw on the inner wall of its through hole.

[0006] Preferably, one end of the screw rod facing the interior of the baking chamber passes through the baking chamber and is transmission-connected to a motor arranged on the outer wall of the baking chamber.

[0007] Preferably, a limiting hole is further provided at the bottom of the driving block, and a limiting rod arranged parallel to the screw rod slides sequentially through the limiting hole and is fixed on the driving frame.

[0008] Preferably, the connection assembly includes a plurality of connection plates arranged in the cavity, the connection plates spanning across two adjacent distance-adjusting slides, and the connection plates and the positioning boxes on the distance-adjusting slides are arranged in a staggered manner; A positioning rod is provided on the distance-adjusting slide positioning box at the end of the inner direction of the baking room, and connecting rods are provided on the other distance-adjusting slide positioning boxes to sequentially penetrate the positioning boxes and the corresponding connecting plates; The ends of the positioning rod and the connecting rod which are far away from the positioning box are provided with flanges, and the cavity of the distance adjustment frame is also provided with a limiting sliding groove which matches the gap of the flange.

[0009] Preferably, the connecting plate body is provided with a connecting long hole that is slidably matched with the connecting rod, and the positioning box body is provided with a positioning long hole that is slidably matched with the connecting rod or the positioning rod; When the adjusting slides are in contact with each other, the connecting long holes of the connecting plates coincide with the positioning long holes of the corresponding positioning boxes of the distance adjusting slides, and the spacing between the positioning rods and the adjacent connecting rods and the spacing between the connecting rods are the same; One end of the connecting plate facing the baking room is fixedly connected to one end of the adjacent distance-adjusting slide seat positioning box facing the outside, and the other end is free and connected to the long hole to slide in cooperation with the corresponding connecting rod.

[0010] Preferably, the positioning rod and the connecting rod are coaxially provided with a positioning disk located in the positioning box at one end away from the flange, and the top and bottom surfaces of the positioning box are both provided with positioning grooves for matching the positioning disk, and the disk surface of the positioning disk is exposed from the positioning groove to the cavity.

[0011] Preferably, a plurality of positioning protrusions are provided at equal intervals on the bottom box body of the positioning long hole, and the gaps between the positioning protrusions match the gaps between the positioning rods or the connecting rods.

[0012] Preferably, an adjusting rod is further provided in the cavity below the positioning rod and the connecting rod, and a socket which is engaged with the positioning rod or the connecting rod body is provided on the adjusting rod body at positions corresponding to the positioning rod and the connecting rod.

[0013] Preferably, the end of the distance adjustment frame facing the outside is provided with a notch penetrated by the adjustment rod, and the end of the adjustment rod exposed to the outside is provided with a length scale line.

[0014] The working process of the present invention is as follows: First, the present invention is in the initial state before loading, that is, the distance adjustment slides are in contact with each other and located at the end of the distance adjustment frame facing the outside, and the driving slides are in contact with each other and located at the end of the driving frame facing the outside. At this moment, the adjustment rod is located below the positioning rod and the connecting rod and remains separated from the positioning rod and the connecting rod. Then the staff climbs up at the door of the curing room to load the tobacco, and inserts the two ends of the tobacco rod after the tobacco is braided or the tobacco clamp after clamping the tobacco leaves into the grooves of the corresponding distance adjustment slide and the driving slide until all the tobacco loading actions are completed.

[0015] After the manual loading of tobacco is completed, the staff returns to the ground and turns on the motor to drive the lead screw to rotate forward. The lead screw drives the drive block at the end of the internal direction of the baking room through the threaded sleeve, and drives the slide to move along the drive frame toward the inside of the baking room. At the same time, the drive slide moves the corresponding distance adjustment slide (i.e., the distance adjustment slide with a positioning rod) and the connecting plate fixed to it synchronously through the corresponding tobacco rod or tobacco clamp. When the connecting plate of the distance adjustment slide moves to the point where the inner wall of its connecting long hole contacts the connecting rod of the adjacent distance adjustment slide, it will pull the connecting rod and the distance adjustment slide corresponding to the connecting rod to continue moving, and at the same time, it will drive the corresponding driving slide to move synchronously through the tobacco rod or tobacco clamp, so that all the distance adjustment slides and driving slides are linked and driven to achieve equidistant arrangement.

[0016] After baking is completed and moisture is regained, the baking room door is opened, and the motor is controlled to drive the lead screw to rotate in the opposite direction. The lead screw drives the driving block at the end in the direction of the inside of the baking room through the threaded sleeve, and drives the slide to move along the driving frame toward the outside of the baking room. At the same time, the driving slide moves the corresponding distance-adjusting slide (that is, the distance-adjusting slide with a positioning rod) and the connecting plate fixed to it synchronously through the corresponding tobacco rod or tobacco clamp, and in the subsequent movement process, it sequentially touches the adjacent distance-adjusting slides and the driving slide to the initial state. The staff can climb up and unload the tobacco at the door of the baking room.

[0017] In actual baking operations, tobacco leaves of different varieties and different parts have different agronomic characteristics such as width and thickness, so the spacing between them in the baking room needs to be adjusted to meet the uniformity of hot air distribution during the curing process and the effective dehumidification process requirements of tobacco leaves during the yellowing period. Therefore, the present invention can change the spacing between adjacent driving slides and adjacent distance-adjusting slides after loading tobacco by the following operations: First, adjust the driving slide and the distance adjustment slide to the initial state, in which the clamp on the adjustment rod can correspond to the positioning rod and the connecting rod of each distance adjustment slide; then lift the adjustment rod along the notch so that the clamp of the adjustment rod can clamp the corresponding positioning rod and connecting rod above, and make the positioning rod and connecting rod move up and out of the positioning protrusion gap at the corresponding positioning long hole. Then move the adjustment rod horizontally outward or inward, so that the positioning rod and connecting rod move above the inside of the positioning long hole and the connecting long hole, and change the distance between the end of the connecting long hole of the corresponding connecting plate, then move the adjustment rod downward, and make the adjustment rod fall into the positioning protrusion groove below, so as to finally achieve the maximum distance adjustment of adjacent distance adjustment slides.

[0018] Compared with the prior art, the present invention has the following advantages: 1) The present invention has a simple structure and can effectively realize the equidistant arrangement of tobacco leaf carriers in the curing room. At the same time, the tobacco leaf carriers can be loaded and unloaded at the door of the curing room, which has a larger operating space.

[0019] 2) The present invention can adjust the distance between adjacent tobacco leaf carriers according to the agronomic properties of the tobacco leaves to be cured, such as width and thickness, thereby adjusting the density of tobacco leaves in the curing room and improving the fluidity of the hot air flow in the curing room.

[0023] The distance adjusting frame 2 is provided with a cavity 21 extending along its length direction, and a positioning box 41 is provided on the side of the distance adjusting slide 4 away from the driving slide 5. The positioning box 41 is provided with a positioning long hole 42.

Several positioning protrusions 43 are provided at equal intervals on the bottom of the positioning long hole 42, and the gaps of the positioning protrusions 43 match the gaps of the corresponding positioning rods 410 or connecting rods 45.

[0024] Several connecting plates 48 arranged in the cavity 21 span across two adjacent adjustable distance slides 4, and the connecting plates 48 and the positioning boxes 41 on the adjustable distance slides are arranged in a staggered manner: a connecting long hole 49 is opened on the plate body of the connecting plate 48, one end of the connecting plate 48 facing the baking room is fixedly connected to one end of the adjacent adjustable distance slide positioning box 41 facing the outside, and the other end freely extends to the end of the corresponding adjustable distance slide positioning box 41 facing the outside, and the connecting rod 45 on the corresponding adjustable distance slide passes through the connecting long hole 49 at the free end of the connecting plate 48; The ends of the positioning rod 410 and the connecting rod 45 away from the positioning box 41 are provided with flanges 47, and the cavity 21 of the adjustable distance frame 2 is also provided with a limiting slide groove 22 that matches the flange 47 with a clearance.

[0025] An adjusting rod 6 is further provided in the cavity 21 below the positioning rod 410 and the connecting rod 45. A clamping seat 61 is provided on the adjusting rod 6 body at the corresponding positioning rod 410 and the connecting rod 45 to be clamped with the positioning rod or the connecting rod body. A notch is provided at one end of the distance adjustment frame 2 facing the outside through which the adjusting rod penetrates, and a length scale is provided at one end of the adjusting rod 6 exposed to the outside.

[0026] The adjusting slides 4 are in contact with each other, the connecting long holes 49 of the connecting plates 48 coincide with the positioning long holes 42 of the corresponding adjusting slide positioning boxes, and the spacing between the positioning rods 410 and the adjacent connecting rods 45 and the spacing between the connecting rods 45 are the same.

[0027] The working process of the present invention is as follows: First, the present invention is in the initial state before loading, that is, the distance adjustment slides 4 are in contact with each other and located at the end of the distance adjustment frame 2 facing the outside, and the driving slides 5 are in contact with each other and located at the end of the driving frame 1 facing the outside. At this moment, the adjustment rod 6 is located below the positioning rod 410 and the connecting rod 45 and remains separated from the positioning rod 410 and the connecting rod 45. Then the staff climbs up at the door of the curing room to load the tobacco, and inserts the two ends of the tobacco rod after the tobacco is braided or the tobacco clamp after clamping the tobacco leaves into the grooves 3 corresponding to the distance adjustment slide 4 and the driving slide 5 until all the tobacco loading actions are completed.

[0028] After the manual loading of cigarettes is completed, the staff returns to the ground and turns on the motor 14 to drive the lead screw 13 to rotate forward. The lead screw 13 drives the drive block 51 at the end of the internal direction of the curing room through the threaded sleeve 54, and drives the slide 5 to move along the drive frame 1 toward the inside of the curing room. At the same time, the drive slide 5 moves the corresponding distance adjustment slide 4 (i.e., the distance adjustment slide with the positioning rod 410) and the connecting plate 48 fixed to it through the corresponding cigarette rod or cigarette clamp. When the connecting plate 48 of the distance adjustment slide 4 moves to the point where the inner wall of its connecting long hole 49 contacts the connecting rod 45 of the adjacent distance adjustment slide 4, it will pull the connecting rod 45 and the distance adjustment slide 4 corresponding to the connecting rod 45 to continue to move, and at the same time, it will drive the corresponding driving slide 5 to move synchronously through the cigarette rod or cigarette clamp, so that all the distance adjustment slides 4 and driving slides 5 are linked and driven to be arranged at equal distances.

[0029] After baking is completed and moisture is regained, the baking room door is opened, and the motor 14 is controlled to drive the screw rod 13 to rotate in the opposite direction. The screw rod 13 drives the driving block 51 at the end in the direction of the inside of the baking room through the threaded sleeve 54, and drives the slide 5 to move along the driving frame 1 toward the outside of the baking room. At the same time, the driving slide 5 moves the corresponding distance-adjusting slide 4 (that is, the distance-adjusting slide with a positioning rod 410) and the connecting plate 48 fixed to it synchronously through the corresponding tobacco rod or tobacco clamp, and in the subsequent movement process, it sequentially touches the adjacent distance-adjusting slide 4 and the driving slide 5 to the initial state. The staff can climb up and unload the tobacco at the door of the baking room.

[0030] In actual baking operations, tobacco leaves of different varieties and different parts have different agronomic characteristics such as width and thickness, so the spacing between them in the baking room needs to be adjusted to meet the uniformity of hot air distribution during the curing process and the effective dehumidification process requirements of tobacco leaves during the yellowing period. Therefore, the present invention can change the spacing between adjacent driving slides and adjacent distance-adjusting slides after loading tobacco by the following operations: First, the driving slide 5 and the distance adjustment slide 4 are adjusted to the initial state, in which the clamping seat 61 on the adjustment rod 6 can correspond to the positioning rod 410 and the connecting rod 45 of each distance adjustment slide 4; then the adjustment rod 6 is lifted up along the notch, so that the clamping seat 61 of the adjustment rod 6 can clamp the corresponding positioning rod 410 and the connecting rod 45 above, and the positioning rod 410 and the connecting rod 45 move up and out of the gap between the positioning protrusion 43 at the corresponding positioning long hole 42. Then the adjustment rod 6 is moved horizontally outward or inward, so that the positioning rod 410 and the connecting rod 45 move above the inside of the positioning long hole 42 and the connecting long hole 49, and the distance between the end of the connecting long hole 49 and the corresponding connecting plate 48 is changed, and then the adjustment rod 6 is moved downward, so that the adjustment rod 6 falls into the gap between the positioning protrusion 43 below, and finally the maximum distance adjustment of the adjacent distance adjustment slides 4 is achieved.
