Description

Technical Field

[0001] The present invention relates to the technical field of tobacco processing equipment, and particularly relates to a blowing device for tobacco leaf rewetting. Background Art

[0002] Fresh tobacco leaves harvested from tobacco fields need to be baked and then supplied to tobacco production enterprises. After being baked and dried, the tobacco leaves become crispy and are not suitable for sorting, packaging, and transportation. Therefore, softening the tobacco leaves by rewetting them and maintaining a certain humidity is an essential process step during tobacco leaf purchasing and storage. Currently, when humidifying tobacco leaves, the tobacco leaves are suspended in a drying room, clamped and hung on a chain that can move in a cycle, and a nozzle is set at a specified position on the chain. This nozzle is used to spray steam for rewetting the tobacco leaves passing through the nozzle. However, in this tobacco leaf rewetting method, due to the relatively fixed spraying position, the humidity of the tobacco leaves near one end of the nozzle is inconsistent with that of the tobacco leaves far from the nozzle end, which affects the uniform rewetting operation of the entire batch of tobacco leaves and further affects the quality of the tobacco leaves.

[0060] The blowing device for tobacco leaf rewetting includes a steam mechanism and a connecting pipe. The steam mechanism is used to output steam, and the inlet end of the connecting pipe is connected to the output end of the steam mechanism. In this embodiment, the blowing device for tobacco leaf rewetting further includes:

[0061] A fixed seat 1, the fixed seat 1 is sleeved on the outlet end of the connecting pipe and is in communication with the connecting pipe. The fixed seat 1 is provided with a steam outlet 11;

[0062] A connecting branch pipe 21, the inlet end of the connecting branch pipe 21 is connected to the fixed seat 1 and is in communication with the steam outlet 11;

[0063] An upper branch pipe 22 and a lower branch pipe 23, the inlet end of the upper branch pipe 22 and the inlet end of the lower branch pipe 23 are connected and in communication with the outlet end of the connecting branch pipe 21;

[0064] The support 4 is connected to the outlet end of the connecting branch pipe 21. The support 4 extends in the vertical direction, and the two ends of the support 4 are respectively provided with a first cross frame 41 and a second cross frame 42 that extend in the horizontal direction.

[0065] The first moving mechanism 5 is arranged on the first cross frame 41.

[0066] The second moving mechanism 6 is arranged on the second cross frame 42.

[0067] The first spraying mechanism 71 is connected to the output end of the first moving mechanism 5. The first moving mechanism 5 is used to drive the first spraying mechanism 71 to reciprocate along the extending direction of the first cross frame 41. The inlet end of the first spraying mechanism 71 is connected to the upper branch pipe 22.

[0068] The second spraying mechanism 72 is connected to the output end of the second moving mechanism 6. The second moving mechanism 6 is used to drive the second spraying mechanism 72 to reciprocate along the extending direction of the second cross frame 42. The inlet end of the second spraying mechanism 72 is connected to the lower branch pipe 23.

[0069] With the above technical solution, the blowing device is fixed at the position where the rewetting operation is to be carried out through the fixing seat 1, and the tobacco leaves pass between the first cross frame 41 and the second cross frame 42. The steam output by the steam mechanism passes through the fixing seat 1 and the connecting branch pipe 21 in sequence and is divided into two paths. One path passes through the upper branch pipe 22 to the first spraying mechanism 71, and the other path passes through the lower branch pipe 23 to the second spraying mechanism 72. The first spraying mechanism 71 and the second spraying mechanism 72 are respectively located on the upper and lower sides of the tobacco leaves, so as to carry out the rewetting operation on the tobacco leaves located between the two spraying mechanisms, that is, the rewetting operation can be carried out on the tobacco leaves from the upper and lower sides in the length direction (vertical direction, such as Figure 1 shown by the x direction in). The first moving mechanism 5 and the second moving mechanism 6 are respectively used to move the first spraying mechanism 71 and the second spraying mechanism 72 in the horizontal direction, so that the rewetting operation can be carried out back and forth on the tobacco leaves in the thickness direction (the direction in which the first cross frame and the second cross frame extend, such as Figure 1 shown by the y direction in). The blowing device provided by the present invention can form convection in the vertical direction, and can make the first spraying mechanism 71 and the second spraying mechanism 72 reciprocate in the horizontal direction to spray steam evenly on the tobacco leaves, so as to realize uniform rewetting operation and ensure the quality of the tobacco leaves.

[0070] Specifically, the steam mechanism is used to output steam, and its output end is connected to the inlet end of the connecting pipe. Optionally, the steam mechanism is a low-pressure steam tank. After the low-pressure steam tank is opened, steam is output from the output end of the low-pressure steam tank and enters the inlet end of the connecting pipe, and the steam is transported to the preset position through the connecting pipe.

[0071] In this embodiment, a platform is provided at a preset position for pre-moistening tobacco leaves. The fixed seat 1 is fixed on this platform. The bottom of the second cross-frame 42 can be seated on this platform so that the bracket 4 is also placed on this platform. The first cross-frame 41 and the second cross-frame 42 extend to the upper and lower sides of the suspended tobacco leaves, and the suspended tobacco leaves are located between the first cross-frame 41 and the second cross-frame 42. The connecting pipe extends from the steam mechanism to the fixed seat 1 of the blowing device. Steam enters the fixed seat 1 from the connecting pipe and enters the connecting branch pipe 21 through the connecting branch pipe 21 provided on the fixed seat 1. An upper branch pipe 22 and a lower branch pipe 23 are connected to the outlet end of the connecting branch pipe 21. Among them, the upper branch pipe 22 extends upward along the bracket 4 to the first cross-frame 41, and its outlet end is communicated with the first spraying mechanism 71; the lower branch pipe 23 extends downward along the bracket 4 to the second cross-frame 42, and its outlet end is communicated with the second spraying mechanism 72. Thus, the steam in the connecting branch pipe 21 respectively enters the first spraying mechanism 71 and the second spraying mechanism 72 after passing through the upper branch pipe 22 and the lower branch pipe 23 at the outlet end of the connecting branch pipe 21, and the tobacco leaves suspended between the first cross-frame 41 and the second cross-frame 42 are moistened through the first spraying mechanism 71 and the second spraying mechanism 72.

[0072] Further, a partition plate 43 is provided in the middle of the bracket 4. The blowing device further includes:

[0075] Adopting this technical solution, by moving the first cross-frame 41 and the second cross-frame 42 in the vertical direction respectively through the third moving mechanism 81 and the fourth moving mechanism 82, it is convenient to adjust the distance between the first cross-frame 41 and the second cross-frame 42 according to the length of the tobacco leaves, and further adjust the distance between the first spraying mechanism 71 and the second spraying mechanism 72.

The third moving mechanism 81 is connected to the first sliding block 411; one end of the second cross-frame 42 close to the bracket 4 is provided with a second sliding block 421, and the second sliding block 421 is slidably connected to the second sliding groove 45. The fourth moving mechanism 82 is connected to the second sliding block 421.

[0077] Specifically, in this embodiment, the bracket 4 extends in the vertical direction. A partition 43 is provided in the middle of one side of the bracket 4, and the middle of the other side is fixedly connected to the outlet end of the connecting branch pipe 21.

[0078] Further, both the third moving mechanism 81 and the fourth moving mechanism 82 are electric push rods. Thus, the first cross frame 41 and the second cross frame 42 can be automatically moved in the vertical direction.

[0079] Further, the first moving mechanism 5 includes a first driving unit 51 and a third sliding block 52. A third sliding groove 412 extending along its length direction is provided on the first cross frame 41. The third sliding block 52 is slidably connected to the third sliding groove 412, and the first spraying mechanism 71 is connected to the third sliding block 52; the second moving mechanism 6 includes a second driving unit 61 and a fourth sliding block 62. A fourth sliding groove 422 extending along its length direction is provided on the second cross frame 42. The fourth sliding block 62 is slidably connected to the fourth sliding groove 422, and the second spraying mechanism 72 is connected to the fourth sliding block 62.

[0080] Specifically, the third sliding groove 412 is provided on the first cross frame 41 extending along the length direction of the first cross frame 41, and the fourth sliding groove 422 is provided on the second cross frame 42 extending along the length direction of the second cross frame 42. Optionally, in this embodiment, the third sliding groove 412 and the fourth sliding groove 422 are through grooves that are open from top to bottom. The third sliding block 52 of the first moving mechanism 5 is arranged in the third sliding groove 412 and is slidably connected to the third sliding groove 412, and the fourth sliding block 62 of the second moving mechanism 6 is arranged in the fourth sliding groove 422 and is slidably connected to the fourth sliding groove 422. The first driving unit 51 drives the third sliding block 52 to reciprocate along the third sliding groove 412, and the second driving unit 61 drives the fourth sliding block 62 to reciprocate along the fourth sliding groove 422, thereby driving the spraying mechanisms on the third sliding block 52 and the fourth sliding block 62 to reciprocate in the horizontal direction.

[0081] Further, both the first driving unit 51 and the second driving unit 61 are electric push rods. Thus, the first spraying mechanism 71 and the second spraying mechanism 72 can be automatically moved in the horizontal direction.

[0082] Further, as Figure 1 、 Figure 2 and Figure 4 shown, the first spraying mechanism 71 and the second spraying mechanism 72 have the same structure, both being sprayers 711. The inlet end of the first spraying mechanism 71 is connected to the outlet end of the upper branch pipe 22 through a connecting hose, and the inlet end of the second spraying mechanism 72 is connected to the outlet end of the lower branch pipe 23 through a connecting hose. A plurality of spray holes 7111 are provided on one side surface of the sprayer 711. The spray holes 7111 on the first spraying mechanism 71 are arranged downward, and the spray holes 7111 on the second spraying mechanism 72 are arranged upward.

[0083] Specifically, through holes for the connecting hoses to pass through are provided on both the third slider 52 and the fourth slider 62. The connecting hoses pass through these through holes to connect the upper branch pipe 22 with the sprayer 711 and the lower branch pipe 23 with the sprayer 711. The steam output from the connecting branch pipe 21, one path of the steam passes through the upper branch pipe 22, the connecting hose and the sprayer 711 and then sprays steam from the spray holes 7111 towards the tobacco leaves from above the tobacco leaves, and the other path of the steam passes through the lower branch pipe 23, the connecting hose and the sprayer 711 and then sprays steam from the spray holes 7111 towards the tobacco leaves from below the tobacco leaves, realizing the spraying of steam on both the upper and lower sides of the tobacco leaves.

[0084] Further, the spray holes 7111 on the first spraying mechanism 71 and the spray holes 7111 on the second spraying mechanism 72 are arranged oppositely. With this technical solution, steam is sprayed from both the upper and lower sides of the tobacco leaves, forming a convection in the up and down directions to achieve uniform moisture regain.

One end of the spray pipe 713 is a closed end, and the other end is an open end, and the open end faces the spray holes 7111;

[0088] The diversion pipe 714 extends in the vertical direction. One end of the diversion pipe 714 is connected to the output end of the compressed air pump 712, and the other end passes through the first through hole 7112 and is connected to the nozzle 713.

[0089] With this technical solution, after the air is obtained from the inside of the compressed air pump 712 through the diversion pipe 714 provided on the nozzle 713, it is blown from the open end of the nozzle 713 onto the steam sprayed out from the spray holes 7111. Under the action of the air sprayed out from the nozzle 713, a turbulent flow is formed for the steam sprayed out from the spray holes 7111, so that the steam sprayed out from the spray holes 7111 can more widely cover and moisten the current tobacco leaves.

[0090] Specifically, for the first spraying mechanism 71, the compressed air pump 712 is arranged on the third slider 52. The compressed air pump 712 is connected to the nozzle 713 through the diversion pipe 714 to convey air to the nozzle 713. The air conveyed to the nozzle 713 is blown from the open end of the nozzle 713 onto the steam sprayed out from the spray holes 7111. The structure of the second spraying mechanism 72 is the same as that of the first spraying mechanism 71, and will not be elaborated here.

[0091] Optionally, the spray holes 7111 are arranged in a circular array and evenly distributed on the surface of the sprayer 711 along the circumferential direction of the sprayer 711. Thus, the steam can be sprayed out evenly.

[0092] Furthermore, the open end of the nozzle 713 is in the shape of a horn that expands outward. With this technical solution, the speed of the sprayed air can be slowed down so as not to blow away the steam, and the area of the sprayed air can be enlarged.

[0093] Furthermore, the first spraying mechanism 71 and the second spraying mechanism 72 further include:

[0094] The mounting seat 715. The mounting seat 715 in the first spraying mechanism 71 is arranged between the third slider 52 and the sprayer 711, and the mounting seat 715 in the second spraying mechanism 72 is arranged between the fourth slider 62 and the sprayer 711. A second through hole is provided in the middle of the mounting seat 715;

[0097] The rotary joint 717 includes a stator 7171 and a rotor 7172. A communicating air passage is provided between the stator 7171 and the rotor 7172. The output end of the transmission mechanism 719 is connected to the rotor 7172. The air outlet end of the rotor 7172 is connected to the closed end of the nozzle 713. The air inlet end of the stator 7171 of the rotary joint 717 is connected to the diversion pipe 714.

[0098] Specifically, as Figure 5 shown, the stator 7171 of the rotary joint 717 is connected to the diversion pipe 714, and the rotor 7172 is connected to the nozzle 713 through the nozzle connecting pipe 718. Thus, an air flow channel is formed among the diversion pipe 714, the stator 7171 of the rotary joint 717, the communicating air passage between the stator 7171 and the rotor 7172, the rotor 7172 of the rotary joint 717, the nozzle connecting pipe 718 and the nozzle 713 to deliver the air in the compressed air pump 712 to the nozzle 713 and spray it out from the open end of the nozzle 713. The air outlet end of the nozzle connecting pipe 718 connecting the rotor 7172 is connected above the end of the closed end of the nozzle 713, and the motor 716 is connected to the rotor 7172 of the rotary joint 717 through the transmission mechanism 719 to drive the rotor 7172 to rotate. Thus, the nozzle 713 makes a circular motion with the closed end as the center, and the air sprayed out from the nozzle 713 can form a turbulent flow for the steam sprayed from the spray holes 7111 circumferentially arranged on the sprayer 711, thereby improving the area of the steam covering the tobacco leaves.

[0099] Further, it further includes a humidity sensor 91, and the humidity sensor 91 is arranged on the side wall of the partition plate 43.

[0100] Specifically, in this embodiment, the humidity sensor 91 is used to detect the humidity of the tobacco leaves before using the blowing device to detect the initial humidity of the tobacco leaves. Optionally, after using the blowing device, the humidity of the tobacco leaves can also be detected to detect the humidity of the rehumidified tobacco leaves.

[0101] Further, it further includes a fifth driving unit 92. The fifth driving unit 92 is arranged on the side wall of the partition plate 43. The driving end of the fifth driving unit 92 is connected to the humidity sensor 91 and is used to drive the humidity sensor 91 to move in a direction parallel to the first cross frame 41 and the second cross frame 42.

[0102] Adopting this technical solution, the humidity sensor 91 is extended towards the tobacco leaves through the fifth driving unit 92 to detect the humidity in the middle of the tobacco leaves.

[0103] Optionally, the fifth driving unit 92 is an electric push rod.

[0104] For the convenience of installing and maintaining the humidity sensor 91, a mounting plate 921 can be installed at the driving end of the fifth driving unit 92, and the humidity sensor 91 is installed on the mounting plate 921.

[0105] Optionally, it further includes a display unit 101, which is arranged on the bracket 4 and electrically connected to the humidity sensor 91 for displaying the humidity of the tobacco leaves detected by the humidity sensor 91.

[0106] Furthermore, both the upper branch pipe 22 and the lower branch pipe 23 are metal hoses. Thus, it can adapt to the installation environment and facilitate displacement.

[0107] Furthermore, the inlet ends of the upper branch pipe 22 and the lower branch pipe 23 are symmetrically arranged on both sides of the connecting branch pipe 21 with respect to the axis of the connecting branch pipe 21.

[0108] Adopting this technical solution facilitates connecting the upper branch pipe 22 and the lower branch pipe 23 to the first spraying mechanism 71 and the second spraying mechanism 72 respectively.

[0109] Furthermore, the fixing seat 1 includes:

[0112] Specifically, the bottom of the base 12 is annular, the third through hole is provided on the base 12, and the pipe clamping mechanism 121 is arranged above the bottom and outside the third through hole. The outlet end of the connecting pipe is inserted into the interior of the base 12 through the third through hole at the bottom and is clamped by the pipe clamping mechanism 121 from the outside of the connecting pipe. The connecting seat 13 is arranged on the base 12 and outside the pipe clamping mechanism 121, and the upper end of the connecting seat 13 is an open end.

[0113] The outer diameter of the bottom of the base 12 is larger than the outer diameter of the connecting seat 13. A plurality of mounting holes are arranged in an annular array along the circumferential direction of the base 12. The mounting holes are located outside the connecting seat 13 to fix the base 12 at a specified position through the mounting holes.

[0114] Furthermore, the fixing seat 1 further includes a metal expansion pipe 14. The lower end of the metal expansion pipe 14 is communicated with the open end of the connecting seat 13, and the upper end of the metal expansion pipe 14 is a steam outlet 11.

[0115] With this technical solution, when adjusting the distance between the first cross-frame 41 and the second cross-frame 42, for example, when the third moving mechanism 81 and the fourth moving mechanism 82 move outward along the support 4, the position of the center of the support 4 relative to the platform rises. By arranging a metal expansion tube 14 between the fixed seat 1 and the connecting branch pipe 21, it is convenient to synchronously lift and lower the height of the support 4 relative to the platform when adjusting the positions of the first cross-frame 41 and the second cross-frame 42 on the support 4.

[0116] Optionally, the connecting branch pipe 21 is a metal pipe.

[0117] Furthermore, the pipe clamping mechanism 121 includes:

[0118] a first jacket 1211 and a second jacket 1212, both the first jacket 1211 and the second jacket 1212 are arc-shaped, and the first jacket 1211 and the second jacket 1212 can move towards and away from each other; when the first jacket 1211 and the second jacket 1212 move towards each other, the first jacket 1211 and the second jacket 1212 can clamp the connecting pipe;

[0119] a plurality of elastic members 1213, which are arranged at intervals along the circumference of the connecting seat 13 inside the connecting seat 13, one end of the elastic member 1213 is connected to the outer circumferential surface of the first jacket 1211 or the second jacket 1212, and the other end is connected to the inner side wall of the connecting seat 13;

[0120] two limiting rods 1214, there are two limiting holes provided on the connecting seat 13, the two limiting holes are respectively opposite to the first jacket 1211 and the second jacket 1212, the two limiting rods 1214 respectively pass through the two limiting holes, one of the limiting rods 1214 is fixedly connected to the outside of the first jacket 1211, and the other limiting rod 1214 is fixedly connected to the outside of the second jacket 1212.

[0121] Specifically, the first jacket 1211 and the second jacket 1212 are arranged to be arc-shaped so that the inner side wall of the jacket fits the outer side wall of the connecting pipe. Optionally, the inner diameter of the third through hole is adapted to the outer diameter of the connecting pipe, so that when the connecting pipe passes through the third through hole and the first jacket 1211 and the second jacket 1212 clamp the connecting pipe, the first jacket 1211 and the second jacket 1212 are butted against each other, and the steam ejected from the outlet end of the connecting pipe flows towards the open end of the connecting seat 13.

[0122] Optionally, the bottom of the first jacket 1211 is provided with a first tail extending outward, and the bottom of the second jacket 1212 is provided with a second tail extending outward. Both the first tail and the second tail are semi-circular rings and are in contact with the upper surface outside the third through hole of the base 12. The first tail and the second tail can be translated along the upper surface of the base 12. When the first jacket 1211 and the second jacket 1212 clamp the connecting pipe, the first jacket 1211 and the second jacket 1212 are butted against each other, and the first tail and the second tail can cover the third through hole. Thus, after the steam in the connecting pipe enters the fixing seat 1, the steam entering the fixing seat 1 is output from the steam outlet 11.

[0123] Two limiting holes are provided on the connecting seat 13. The two limiting holes are arranged opposite to each other and are respectively opposite to the first jacket 1211 and the second jacket 1212. Among them, after the distal end of one limiting rod 1214 is inserted through one limiting hole, it is fixedly connected to the outside of the first jacket 1211.

[0124] A plurality of elastic members 1213 are provided between the jacket and the connecting seat 13. One end of the elastic member 1213 is fixedly connected to the outer side wall of the jacket, and the other end is fixedly connected to the inner side wall of the connecting seat 13. Optionally, the elastic member 1213 is a spring.

[0125] Optionally, there are four elastic members 1213.

These four elastic members 1213 are on the same horizontal plane.

[0126] Optionally, the limiting rod 1214 is a threaded rod, and the limiting hole is a threaded hole.

[0127] In the initial position, the first jacket 1211 and the second jacket 1212 are away from each other, and the spring is in a natural relaxed state. By rotating the two limiting rods 1214 to push the first jacket 1211 and the second jacket 1212 inward, the first jacket 1211 and the second jacket 1212 clamp the connecting pipe, and the spring is stretched. When the two limiting rods 1214 are rotated in the reverse direction, the first jacket 1211 and the second jacket 1212 are pulled back under the elastic action of the spring, and the first jacket 1211 and the second jacket 1212 release the clamping of the connecting pipe.

[0128] Optionally, handles 102 are symmetrically provided on the outer side wall of the bracket 4 so as to hold the blowing device during the process of moving the first cross frame 41 and the second cross frame 42 to appropriate positions by the third moving mechanism 81 and the fourth moving mechanism 82.

[0129] The working principle of the blowing device for tobacco leaf rewetting provided by the present invention: Hang the tobacco leaves on the conveying chain in the tobacco curing barn. On the platform below the chain, place the base 12 on the platform and place the first cross frame 41 on the platform. The first jacket 1211 and the second jacket 1212 are sleeved on the outer side of the connecting pipe. The base 12 is fixedly installed by passing the fixing bolts through the installation holes opened on the base 12. Rotate the two limit rods 1214 installed on the connecting seat 13 to push the first jacket 1211 and the second jacket 1212 inward, and clamp the connecting pipe through the two jackets. At this time, the operator can hold the two handles 102 outside the bracket 4 to hold the blowing device.

[0130] After that, according to the length of the currently hung tobacco leaves, the first cross frame 41 and the second cross frame 42 are pushed outward in the vertical direction through the third moving mechanism 81 and the fourth moving mechanism on the bracket 4. When the first cross frame 41 and the second cross frame 42 are extended to a suitable distance, the tobacco leaves are located between the first cross frame 41 and the second cross frame 42. Drive the humidity sensor 91 toward one side of the tobacco leaves through the fifth driving unit 92, push the humidity sensor 91 into the tobacco leaves, so that the humidity sensor 91 is inserted into the tobacco leaves for humidity detection, and display the current humidity of the tobacco leaves through the display unit 101 at the front end of the bracket 4.

[0131] After the humidity detection of the current tobacco leaves is completed, through the first driving unit 51 and the second driving unit 61, the third slider 52 reciprocates along the third chute 412 on the first cross frame 41, and at the same time, the fourth slider 62 reciprocates along the fourth chute 422 on the second cross frame 42.

[0132] The steam output by the steam mechanism sequentially passes through the connecting pipe, the connecting seat 13, the metal expansion pipe 14, and the connecting branch pipe 21. One way of steam enters the first spraying mechanism 71 through the upper branch pipe 22, and the other way passes through the lower branch pipe 23 to enter the second spraying mechanism 72. The first spraying mechanism 71 and the second spraying mechanism 72 spray steam from the upper and lower sides of the tobacco leaves respectively. Among them, the steam output from the upper branch pipe 22 is sprayed out through the spray holes 7111 of the sprayer 711. At the same time, the air output by the compressed air pump 712 passes through the guide pipe 714, the rotary joint 717, and the spray pipe 713, and is blown from the open end of the spray pipe 713 onto the steam sprayed out from the spray holes 7111. The steam output from the lower branch pipe 23 is the same.

[0133] During the rewetting operation, the first spraying mechanism 71 and the second spraying mechanism 72 reciprocally move in a cyclic manner in the horizontal direction, and by rotating the open end of the spray nozzle 713, the air ejected from the spray nozzle 713 is cyclically sprayed onto the steam sprayed from the spray holes 7111. Therefore, under the blowing action of the air from the spray nozzle 713, the steam sprayed from the spray holes 7111 can be more widely applied to the current tobacco leaves, realizing a uniform rewetting operation.

[0134] The blowing device for tobacco leaf rewetting provided by the present invention can realize a uniform rewetting operation, ensure the quality of tobacco leaves, and the device can automatically move the spraying mechanism, which can improve production efficiency and reduce production costs.
