Description

Technical Field

[0001] The invention relates to the technical field of tobacco leaf loading on a bed, and in particular to a tobacco leaf loading on a bed equipment. Background Art

[0002] Loading tobacco leaves refers to the process of loading fresh tobacco leaves into the curing room. Curing rooms are usually divided into three layers: upper, middle and lower. The height of each layer from the ground is 2.9m, 2.1m and 1.8m respectively. Fresh tobacco leaves after harvesting should be loaded and baked in time. The traditional manual loading method is to load tobacco leaves into tobacco clips during baking, and then load each loaded tobacco clip into the curing room. Each tobacco clip is loaded with about 20kg of tobacco leaves, and a curing room can load about 380 tobacco clips. If tobacco leaves are loaded into the curing room manually, it takes about 3 strong laborers to load a curing room, and it takes 3 hours to complete the loading of tobacco leaves in a curing room. If there are 20 curing rooms, more manpower is required. In addition, due to the high temperature of the curing room, it is difficult to load tobacco in the upper and middle layers, the labor intensity is high, and long-term work is prone to fatigue and reduced efficiency.

[0003] Traditional automatic tobacco loading and unloading platforms usually place tobacco clips on the platform first, and can hold about 10 tobacco clips at a time. A worker is needed on the platform, and the platform rises. The worker manually loads the tobacco clips to the upper and middle tobacco beams. After loading, the platform descends, exits the curing room, reloads tobacco clips, and repeats the process of loading. However, the loading and unloading trolleys used in this type of loading and unloading platform need to repeatedly enter and exit the narrow and long curing room. Since the single row of the curing room is only 1.39 meters wide and 8 meters long, the space is narrow and long. Therefore, the size of the equipment and the movement in the curing room are greatly restricted. The position of the platform needs to be constantly adjusted to avoid collision with the curing room during the loading process, which threatens the safety of workers. In addition, the operation efficiency is low and the operation is inflexible. Summary of the invention

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] The purpose of the present invention is to provide a tobacco leaf loading equipment to solve the problems existing in the prior art and to make the loading process highly stable, flexible in operation, low in labor intensity and high in operation efficiency.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1-Figure 5 As shown, the present embodiment provides a tobacco leaf loading equipment, including a base frame 2, a support frame, a lifting mechanism, a pushing mechanism and a loading mechanism. The support frame is installed on one side of the upper end of the base frame 2, and the pushing mechanism is installed on the other side of the upper end of the base frame 2. The pushing mechanism is installed on the support frame, and the pushing mechanism is connected to the lifting mechanism, and can be raised and lowered under the drive of the lifting mechanism to ensure that it can act on the loading mechanism. The loading mechanism is movably connected to the upper end of the support frame, and the loading mechanism is used to load a tobacco clip 19 filled with tobacco leaves. The loading mechanism can be pushed to the lifting mechanism and raised and lowered under the drive of the lifting mechanism, and then can be highly aligned with the corresponding tobacco beam 181 to ensure that the loading mechanism can reach the predetermined tobacco beam 181 position. The pushing mechanism can push the loading mechanism to the tobacco beam 181 of the curing room after the loading mechanism is raised and lowered into place, thereby realizing automatic loading, without the need for manual operation in the curing room, saving labor, and improving operation flexibility and efficiency. At the same time, through the above design, the tobacco leaf loading equipment is designed to be external, and does not need to enter and exit the curing room, which can avoid safety problems such as jamming and improve operation stability.

[0029] Specifically, each corner of the lower end of the bottom frame 2 is respectively equipped with a ground wheel 1, which is convenient for driving the whole to move through the bottom frame 2. The ground wheel 1 can include a set of universal wheels and a set of fixed wheels. The ground wheel 1 is provided with a brake to improve the stability during operation. One side of the bottom frame 2 for placing the loading mechanism forms an operating table 20.

[0030] The supporting frame includes four columns 3 and two cross beams. The four columns 3 are parallel to each other and correspond to the four corners of a rectangle respectively. The lower end of each column 3 is fixed to the upper end of the bottom frame 2, and the upper end of each column 3 extends upward. The two cross beams are arranged in parallel, and the two ends of one of the cross beams are respectively connected to the upper ends of two of the columns 3, and the two ends of the other cross beam are respectively connected to the upper ends of the other two columns 3. The two cross beams are respectively arranged corresponding to the two long sides of the rectangle, which can provide stable support for the lifting mechanism.

[0031] Each column 3 is provided with a guide rail 8, which extends along the length direction of the column 3. The four guide rails 8 are used to slide and connect the lifting mechanism and can guide the lifting mechanism, thereby improving the stability during the lifting process and avoiding the overturning of the loading mechanism due to problems such as sticking.

[0032] The lifting mechanism includes a driving element, a driving shaft 4, a first driven shaft 10, a second driven shaft 12, a third driven shaft 13, a fourth driven shaft 14, two lifting beams 7, a plurality of chains and a plurality of sprockets. The two lifting beams 7 are arranged in parallel, and the two lifting beams 7 are arranged corresponding to the two short sides of the rectangle respectively. The lifting beams 7 are perpendicular to the cross beams. The ends of the two lifting beams 7 are slidably connected to different guide rails 8 respectively. The loading mechanism can be pushed to connect to the two lifting beams 7 so as to realize the lifting and lowering of the loading mechanism. At the same time, the sliding cooperation between the lifting beams 7 and the guide rails 8 improves the stability of the loading mechanism during lifting and lowering.The chain is divided into a lifting chain 9 and a transverse chain 11. The lifting chain 9 is arranged vertically, and the transverse chain 11 is arranged horizontally. The driving element is installed on the bottom frame 2, and the output shaft of the driving element is coaxially connected to the driving shaft 4 to provide driving force. The driving shaft 4 is parallel to the horizontal plane, and the two ends of the driving shaft 4 are respectively rotatably connected to the lower ends of two of the columns 3. The first driven shaft 10 and the third driven shaft 13 correspond to the two short sides of the rectangle respectively, that is, the first driven shaft 10 and the third driven shaft 13 are arranged in parallel on the same horizontal plane, and the first driven shaft 10 and the driving shaft 4 are arranged in parallel on the same vertical plane. The two ends of the first driven shaft 10 are respectively rotatably connected to the upper ends of two of the columns 3. , the two ends of the third driven shaft 13 are respectively rotatably connected to the upper ends of the other two columns 3, the upper end of one of the columns 3 connected to the third driven shaft 13 is rotatably connected to the second driven shaft 12, and the second driven shaft 12 is parallel to the third driven shaft 13, the fourth driven shaft 14 is symmetrically arranged with the driving shaft 4, and the two ends of the fourth driven shaft 14 are respectively rotatably connected to the lower ends of two of the columns 3, that is, the fourth driven shaft 14 and the third driven shaft 13 are arranged in parallel on the same vertical plane, a driving sprocket 5 is coaxially installed on the driving shaft 4, and a first driven sprocket 24 is coaxially installed on the first driven shaft 10, and the driving sprocket 5 and the first driven sprocket 24 are connected through a group of lifting chains 9. Then, the driving shaft 4 is driven to rotate through the driving element, and the driving shaft 4 drives the first driven shaft 10 to rotate through the cooperation of the chain-sprocket, and the rotation direction of the driving shaft 4 and the first driven shaft 10 is the same, a second driven sprocket 25 is coaxially installed on the second driven shaft 12, a third driven sprocket 26 is coaxially installed on the third driven shaft 13, and a fourth driven sprocket 23 is coaxially installed on the fourth driven shaft 14. The third driven sprocket 26 is connected to the fourth driven sprocket 23 through another set of lifting chains 9. Through the cooperation of the chain-sprocket, the third driven shaft 13 drives the fourth driven shaft 14 to rotate in the same direction. The two sets of lifting chains 9 are respectively connected to the two lifting beams 7, so that the lifting of the lifting beams 7 is realized through the two sets of lifting chains 9. The lifting chain 9 drives the two lifting beams 7 to rise and fall at the same time, and one of the first driven sprockets 24 and the second driven sprocket 25 is connected by the transverse chain 11, and the outer ring of the transverse chain 11 is connected by the third driven sprocket 26, so that the third driven shaft 13 and the driving shaft 4 are in the opposite direction, so that the two sets of lifting chains 9 can drive the two lifting beams 7 to rise and fall synchronously. At the same time, because the same driving element is used to drive, the power cost can be reduced, the transmission structure and principle are simple and reliable, and the loading mechanism can be ensured to rise steadily and improve stability. Through the above design, multiple heights of tobacco leaves can be loaded on the kang, with high flexibility, and workers do not need to climb high, eliminating the risk of falling. ;

[0033] There are two driving sprockets 5, two first driven sprockets 24, two third driven sprockets 26 and four driven sprockets 23, and there are two lifting chains 9 in each group. The two driving sprockets 5, two first driven sprockets 24 and two lifting chains 9 in the same group correspond one to one, and the two third driven sprockets 26, two fourth driven sprockets 23 and two lifting chains 9 in the same group correspond one to one, ensuring that each group of lifting chains 9 can drive the corresponding lifting beam 7 to stably lift and lower, avoiding the lifting beam 7 from tilting due to uneven force when lifting with one lifting chain 9, thereby affecting the lifting effect.

[0034] Both ends of the driving shaft 4, both ends of the first driven shaft 10, one end of the second driven shaft 12, both ends of the third driven shaft 13 and both ends of the fourth driven shaft 14 are mounted on the corresponding columns 3 through bearing seats 6 to improve stability during rotation.

[0035] The driving element is a driving motor 21, and the output shaft of the driving motor 21 is connected to one end of the driving shaft 4 through a coupling 22, thereby ensuring effective transmission of the driving force. The power source has a low cost, a simple and reliable structure, and is easier to maintain.

[0036] The loading mechanism is a tray 18, which is used to load cigarette clips 19 filled with tobacco leaves. Preferably, one tray 18 can load five cigarette clips 19. The tray 18 is of a bottom opening type to ensure that the cigarette clips 19 filled with tobacco leaves can smoothly enter the tray 18. There are two symmetrically arranged tobacco beams 181 at the same height, which can limit and guide the two sides of the tray 18. The opening of the tobacco beam 181 is set downward, and the tobacco beam 181 is in a "J" shape. Guide plates are provided under both ends of the tray 18, and the guide plates can be slidably connected to one side of the corresponding tobacco beam 181. The guide plates are guided by the tobacco beam 181 to prevent them from being offset during movement. A roller needle 17 is provided at the lower end of the tray 18 at the position in contact with the tobacco beam 181, which effectively reduces the friction of the tray 18 when it moves along the tobacco beam 181. In addition, it can play a guiding and positioning role for the tray 18, thereby avoiding the occurrence of jamming caused by improper installation of the tobacco beam 181, protruding foreign objects, high friction, etc. during the movement of the tray 18. At the same time, the design of the tray 18 can adapt to the narrow and long space environment of the baking room. Since a single cigarette clip 19 is 12 cm wide and 132.5 cm long, if the pushing mechanism directly acts on the cigarette clip 19, it is very easy to deviate left and right during the pushing process and be stuck by the connecting parts on the cigarette beam 181. In addition, the efficiency of lifting and pushing a single cigarette clip 19 is low. Therefore, a special tray 18 is designed, which can place multiple cigarette clips 19 filled with tobacco leaves on the tray 18 to improve work efficiency.

[0037] The pushing mechanism includes an electric push rod 16 and a hinge shaft 15. The electric push rod 16 is parallel to the horizontal plane, and the fixed end of the electric push rod 16 is installed on the lifting mechanism, so that it can rise and fall with the movement of the lifting mechanism. The fixed end of the electric push rod 16 is preferably installed on the lifting beam 7, and there are two electric push rods 16. The protruding end of the electric push rod 16 extends in the direction close to the lifting mechanism, so that the loading mechanism can be pushed to separate from the lifting mechanism and reach the smoke beam 181. The protruding end of the electric push rod 16 is hinged to the hinge shaft 15. In the initial state, the loading mechanism is located below the electric push rod 16, and the hinge shaft 15 is vertically arranged on one side of the loading mechanism under the action of gravity. When the loading mechanism moves in the direction close to the lifting mechanism, the first end of the loading mechanism can push the hinge shaft 15 to rotate in the direction close to the lifting mechanism. The second end of the loading mechanism moves to the position where the second end of the loading mechanism is disengaged from the hinge shaft 15, and the hinge shaft 15 is reset under the action of gravity, and the hinge shaft 15 is restricted by the head end of the electric push rod 16 and cannot rotate from the vertical state to the direction away from the lifting mechanism, ensuring that the electric push rod 16 can push the loading mechanism to move through the hinge shaft 15. When the electric push rod 16 is extended, it can drive the hinge shaft 15 to extend and push the second end of the loading mechanism to move until the loading mechanism reaches the position of the smoke beam 181. Through the above design, the pushing mechanism can not only push the pallet 18 into the smoke beam 181, but also ensure that the worker pushes the pallet 18 from the operating table 20 to the lifting beam 7 smoothly. At the same time, the equipment does not need to enter and exit the baking room, which is more convenient and flexible, avoiding high-risk risks such as collision between the equipment and the baking room, collision between the equipment and people, and smoke clips 19 falling and hitting workers.

[0038] The working principle of this embodiment is:

[0039] First, move the tobacco loading equipment outside the curing room, lock the brake of the ground wheel 1, place the tray 18 on the bottom frame 2, and after the worker puts the tobacco clips 19 loaded with tobacco into the slots on the tray 18, push the tray 18 to the lifting beam 7, start the drive motor 21 to rotate clockwise, output torque through the coupling 22, and drive the driving shaft 4 to rotate. The driving shaft 4 and the first driven shaft 10, the third driven shaft 13 and the fourth driven shaft 14 all transmit power through the lifting chain 9, among which the first driven shaft 10, the second driven shaft 12 and the third driven shaft 13 are driven by the lifting chain 9. The power transmission on both sides is realized and the rotation direction of the third driven shaft 13 is changed through the transverse chain 11. The guide rail 8 is installed on the column 3. The lifting chains 9 on the left and right sides drag the lifting beam 7 along the guide rail 8 to rise synchronously to the predetermined height of the smoke beam 181. The electric push rod 16 is fixed on the lifting beam 7 by extending the cross beam. The electric push rod 16 is extended and pushes the tray 18 into the smoke beam 181 through the hinge shaft 15. Then the electric push rod 16 returns to its original position, and the drive motor 21 reverses. The lifting beam 7 drops to be flush with the operating table 20 to prepare for the next working cycle.

[0040] The tobacco loading equipment is designed with a control system based on a single-chip microcomputer based on the above-mentioned mechanical structure. The control system can control the forward and reverse rotation of the drive motor 21 to complete the rise and fall of the lifting beam 7. The position sensor can detect the position of the lifting beam 7. When the lifting beam 7 rises or falls to the specified position, the position sensor outputs a position signal to the control system, and controls the drive motor 21 to stop rotating, and controls the push and return of the electric push rod 16 through the control system to complete the tobacco loading. In the entire tobacco loading process, except for manual loading, all other processes are automated and intelligent.

[0041] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
