Description

Technical Field

[0001] The present application relates to the field of tobacco leaf baking, and in particular to an automatic tobacco loading and baking device. Background Art

[0002] The comb-type tobacco clip is a tool used for tobacco leaf braiding, which consists of a comb-type tobacco fork and a U-shaped clamp. The comb-type tobacco fork is shaped like a wooden comb, and the steel needles on it are used to pass through the tobacco leaves. The tobacco leaves are fixed by the comb-type tobacco fork and the clamp. After the tobacco is braided, the comb-type tobacco clip is sent to the curing room for tobacco leaf curing, that is, loading. The existing tobacco leaf curing room is equipped with multiple layers of limit grooves from top to bottom for the two ends of the tobacco clip to be embedded, so as to maximize the utilization of the curing room.

[0003] After the tobacco leaves are baked in the curing room, they need to be taken out, that is, baked. At present, the loading and baking of tobacco leaves are mostly done manually. On the one hand, the curing room is large in size and high in height, and workers need to climb up and down using escalators when working. In addition, the comb-type tobacco clips and the tobacco leaves they are inserted with are heavy, which makes them inconvenient to operate, and the baking efficiency is low. On the other hand, the residual temperature in the curing room is high, and long-term work affects the health of workers. Summary of the invention

[0004] In order to improve the efficiency of cigarette loading and baking, the present application provides an automatic cigarette loading and baking device.

[0005] The automatic cigarette loading and baking equipment provided in this application adopts the following technical solution:

[0006] An automatic smoke loading and baking device, comprising a docking device and a transmission component arranged inside a baking room;

[0007] The docking device comprises a base frame, a telescopic arm, a lifting section, a transmission sprocket group and a motor 1. The telescopic arm is provided with two, one end of the two telescopic arms is hinged on the base frame and is located at the same height; the lifting section is provided with two and corresponds to the telescopic arms one by one respectively, and the other end of the lifting section is hinged with a support plate, the telescopic arm is fixedly connected to the support plate, the hinge axis of the telescopic arm and the hinge axis of the support plate are parallel to each other, and the lifting section is used for lifting and lowering to adjust the height of one end of the telescopic arm; the transmission sprocket group is provided with two groups and corresponds to the telescopic arms one by one respectively, and the sprocket of the transmission sprocket group is rotatably connected to the two ends of the telescopic arm, and the sprocket of the transmission sprocket group away from the hinge point between the telescopic arm and the base frame is coaxially provided with a gear ring; the transmission chains of the two transmission sprocket groups are respectively overlapped at the two ends of the comb-type cigarette clamp; the motor 1 is used to drive the sprocket of the transmission sprocket group to rotate;

[0008] The transmission assembly includes a plurality of transmission parts arranged at intervals along the height direction of the baking room, and the transmission parts include two conveyor belts arranged horizontally side by side, and a plurality of driven gears connected to the baking room for rotation, the driven gears are used to drive the conveyor belts to horizontally convey the comb-type cigarette clamps, and the driven gear located at one end of the baking room entrance is used to mesh with the gear ring.

[0009] By adopting the above technical solution, the comb-type cigarette clip is placed on the conveyor chain of the conveyor sprocket group, and the telescopic arm is tilted or pressed down by adjusting the length of the lifting section, so that the higher end of the telescopic arm is aligned with the conveyor belt of the corresponding height in the baking room, and the ring gear is engaged with the driven gear. Then the motor drives the conveyor chain of the conveyor sprocket group to move, and the ring gear drives the driven gear to rotate, and then the conveyor belt runs. The cigarette clip conveyor chain is transported to a high place and sent into the baking room through the conveyor belt. When baking, the cigarette clip is transferred from the conveyor belt to the conveyor chain. The automatic operation of loading and baking is completed, which reduces the burden on personnel and improves work efficiency.

[0010] Preferably, the telescopic arm comprises arm one, arm two and arm three which are parallel to each other, one end of arm one is hinged to the base frame, one end of arm two is fixedly connected to the other end of arm one, and arm three is slidably connected to arm two along its own length direction and is used to dock with arm one.

[0011] By adopting the above technical solution, the sliding arm three can extend or shorten the overall length of the telescopic arm, better adapt to the different heights of the baking room, and make the device more widely used.

[0012] Preferably, the conveying sprocket group includes a conveying chain and four sprockets; the four sprockets are arranged as follows: one sprocket is hinged at one end of arm one close to its hinge point, one sprocket is hinged at both ends of arm three, and the sprocket of arm three close to arm one is lower than another sprocket on arm three, arm two is located below arm three, and one sprocket is hinged at one end of arm two away from arm one; the conveying chain is sequentially wound around the four sprockets to form a conveying chain closed loop, and the sprocket on arm three close to arm one is located outside the closed loop of the conveying chain, and the other sprockets are all located inside the closed loop of the conveying chain.

[0013] By adopting the above technical solution, when the telescopic arm is extended by sliding arm three, there is a situation where arm three cannot be docked with arm one. Generally, two sets of transmission sprocket groups need to be set for arm one and arm three respectively, and the structure is complicated. Now, by using a certain number of sprockets and the winding method of the transmission chain, when the comb-type cigarette clamp is transmitted to arm three through the transmission chain, arm three slides away from arm one. At this time, the sprocket on arm three close to arm one gradually approaches the sprocket on arm two, and the length of the transmission chain between the above two sprockets becomes shorter, and the length of the transmission chain between the sprocket on arm three away from arm one and the sprocket on arm one becomes longer, so that the length of the transmission chain available for transportation can be adjusted. Thereby simplifying the structure of the device and avoiding the problem of difficulty in debugging the matching between the two sets of transmission sprocket groups.

[0014] Preferably, it also includes a motor 2 arranged on arm 2, a rack 1 is provided on arm 3, and motor 2 is provided with a driving gear meshing with rack 1, and motor 2 is used to drive the driving gear to rotate and thereby drive relative sliding between arm 3 and arm 2.

[0015] By adopting the above technical solution, the relative position between arm two and arm three is automatically adjusted back and forth, which further reduces the degree of dependence on personnel, improves the degree of automation of the device, and achieves the purpose of efficient kang climbing.

[0016] Preferably, a limiting protrusion is provided on the conveying chain of the conveying sprocket assembly, and the limiting protrusion is used for abutting the two ends of the comb-type cigarette clamp to prevent the comb-type cigarette clamp from sliding off.

[0017] By adopting the above technical solution, the comb-type cigarette clamps can be prevented from slipping during the conveying process of the conveyor chain, ensuring that the comb-type cigarette clamps are stably delivered to the baking room, thereby improving the reliability of the device.

[0018] Preferably, a plurality of the limiting protrusions are evenly spaced on the same conveying chain.

[0019] By adopting the above technical solution, the cigarette clips are kept at the same distance and sent to the conveyor belt, so that the cigarette clips in the baking room are hung with a reasonable density, thereby improving the baking efficiency.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. Place the comb-type cigarette clip on the conveyor chain of the conveyor sprocket group, and adjust the length of the lifting section to tilt or press the telescopic arm, so that the higher end of the telescopic arm is aligned with the conveyor belt of the corresponding height in the baking room, and the ring gear is meshed with the driven gear. Then the motor drives the conveyor chain of the conveyor sprocket group to move, and the ring gear drives the driven gear to rotate, and then the conveyor belt runs. The cigarette clip conveyor chain is transported to a high place and sent into the baking room through the conveyor belt. When baking, the cigarette clip is transferred from the conveyor belt to the conveyor chain. The automatic operation of loading and baking is completed, which reduces the burden on personnel and improves work efficiency.

[0022] 2. When extending the telescopic arm by sliding arm three, there is a situation where arm three cannot be docked with arm one. Generally, two sets of transmission sprocket groups need to be set for arm one and arm three respectively, and the structure is complicated. Now, by using a certain number of sprockets and the transmission chain winding method, when the comb-type cigarette clamp is transmitted to arm three through the transmission chain, arm three slides away from arm one. At this time, the sprocket on arm three close to arm one gradually approaches the sprocket on arm two, and the length of the transmission chain between the above two sprockets becomes shorter, and the length of the transmission chain between the sprocket on arm three away from arm one and the sprocket on arm one becomes longer, so that the length of the transmission chain available for transportation can be adjusted. Thereby streamlining the device structure and avoiding the problem of difficulty in debugging the matching between the two transmission sprocket groups. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following is combined with Figure 1-3 This application is described in further detail.

[0028] Reference Figure 1 The embodiment of the present application discloses an automatic cigarette loading and baking device including a docking device.

[0029] Reference Figure 2 The docking device includes a base frame 1, a telescopic arm 2, a gantry 3, a transmission sprocket group 4 and a motor 7.

[0030] Two telescopic arms 2 are provided. The telescopic arms 2 include arm 1 21, arm 2 22 and arm 3 23 which are parallel to each other. One end of arm 1 21 is hinged to the base frame 1 and is located at the same height. Arm 2 22 is located below arm 1 21, and one end of arm 22 is fixedly connected to the other end of arm 1 21. Arm 3 23 is slidably connected to arm 2 22 along its length direction and is used to dock with arm 1 21.

[0031] The arm three 23 is provided with a rack one, and the motor two 7 is provided with a driving gear meshing with the rack one. The motor two 7 is used to drive the driving gear to rotate and thereby drive the arm three 23 and the arm two 22 to slide relative to each other.

[0032] The gantry 3 includes a crossbar 31 and vertical rods 32 fixedly connected to both ends of the crossbar 31. The two vertical rods 32 are perpendicular to the crossbar 31 and are located on the same side of the crossbar 31, which is approximately U-shaped. One end of the two vertical rods 32 away from the crossbar 31 is hinged to the base frame 1. The two arms 21 are located between the gantry 3, and the crossbar 31 is located above the arms 21.

[0033] The vertical rod 32 is provided with a rack 2 arranged along its length direction, the vertical rod 32 is slidably sleeved with a mounting sleeve 33, the mounting sleeve 33 is provided with a motor 34, and the output shaft of the motor 34 is coaxially connected with a gear 2 meshing with the rack 2.

[0034] A support plate 35 is hinged on the mounting sleeve 33, and the hinge axis of the support plate 35 is parallel to the hinge axis of the arm 1 21. The arm 1 21 is fixedly connected to the support plate 35, and the lifting section is between the hinge point of the vertical rod 32 on the bottom frame 1 and the support plate 35. When the motor 34 drives the gear 1 to rotate, the mounting sleeve 33 moves up and down along the vertical rod 32, and the distance between the fixed point of the vertical rod 32 on the bottom frame 1 and the support plate 35 is shortened or lengthened, so that the lifting and lowering of the telescopic arm 2 is realized.

[0035] Reference Figure 3 , there are two groups of transmission sprocket groups 4, which correspond to the telescopic arms 2 one by one. The transmission sprocket group 4 includes a transmission chain 42 and four sprockets 41. The four sprockets 41 are arranged as follows: one end of arm 1 21 close to its own hinge point is hinged, and one end of arm 3 23 is hinged; the sprocket 41 of arm 3 23 away from arm 1 21 is higher than the other sprocket 41 on arm 3 23 and is coaxially provided with a gear ring; arm 2 22 is located below arm 3 23, and one end of arm 22 away from arm 1 21 is hinged; the transmission chain 42 is sequentially wound around the four sprockets 41 to form a transmission chain closed loop, and the sprocket 41 on arm 3 23 close to arm 1 21 is located outside the ring of the transmission chain closed loop, and the other sprockets 41 are all located inside the transmission chain closed loop. When the comb-type cigarette clamp is transmitted to arm three 23 through the transmission chain 42, arm three 23 slides to move away from arm one 21. At this time, the sprocket 41 on arm three 23 close to arm one 21 gradually approaches the sprocket 41 on arm two 22, and the length of the transmission chain 42 between the two sprockets 41 becomes shorter, and the length of the transmission chain 42 between the sprocket 41 on arm three 23 away from arm one 21 and the sprocket 41 on arm one 21 becomes longer, thereby realizing the adjustable length of the transmission chain 42 available for transportation.

[0036] A plurality of limiting protrusions spaced apart from each other are evenly arranged on the conveying chain 42, and the spaces between adjacent limiting protrusions are used for placing the two ends of the comb-type cigarette clamp.

[0037] Reference Figure 1 The automatic cigarette loading and baking device also includes a motor 5, a transmission assembly and a stabilizer bar 6.

[0038] The motor 5 is disposed on the arm 21 and is used to rotate the sprocket 41 located on the arm 21.

[0039] The transmission assembly includes a plurality of transmission members 8 arranged at intervals along the height direction of the curing room 0. The transmission member 8 includes a conveyor belt 81 arranged in parallel in the same horizontal plane and a plurality of driven gears 82 driving the conveyor belt 81 to rotate. The driven gear 82 is used to be rotatably connected to the curing room 0. The two conveyor belts 81 located in the same horizontal direction are used for the comb-type cigarette clips to overlap. The driven gear 82 is used to drive the conveyor belt 81 to horizontally convey the comb-type cigarette clips, and the driven gear 82 near the entrance of the curing room 0 is used to mesh with the gear ring.

[0040] The stabilizing rod 6 adopts a U-shaped rod structure, and the two ends of the stabilizing rod 6 are respectively fixedly connected to the two arms 21, and the cross bar 31 in the middle of the stabilizing rod 6 does not interfere with the conveying path of the conveying chain 42. Two stabilizing rods 6 are provided and are respectively located at the two ends of the length direction of the arm 21.

[0041] The implementation principle of the automatic cigarette loading and baking device in the embodiment of the present application is as follows:

[0042] After the cigarettes are arranged, the two ends of the comb-type cigarette clip are overlapped on the arm 1 21 respectively, and the position is limited by the limit protrusion. The lifting section is extended and retracted, and the telescopic arm 2 is adjusted to a suitable height. Then, the motor 1 5 is turned on, and the comb-type cigarette clip is transported from the arm 1 21 to the arm 3 23. Then, the motor 2 7 is turned on to drive the arm 3 23 to slide away from the arm 1 21, and the conveyor belt 81 is driven to rotate through the engagement of the ring gear and the driven gear 82, and then the comb-type cigarette clip is transferred from the conveyor chain 42 to the conveyor belt 81, and the cigarette loading is completed. When baking, the motor 1 5 drives the sprocket 41 to rotate in the opposite direction to take the comb-type cigarette clip out of the baking room 0. The whole process of cigarette loading and baking is realized automatically, which reduces the burden on personnel and improves work efficiency.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
