Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco processing equipment, and particularly relates to an automatic lifting device for a baking room. Background Art

[0002] In the process of making cigarettes, after tobacco farmers pick mature tobacco leaves, they need to bundle the tobacco leaves and then hang them on bamboo poles for support. Then, the bamboo poles are placed in the baking room for baking to remove the moisture in the tobacco leaves, and then the dried tobacco leaves are packed into tobacco bales and sent to the warehouse.

[0003] Currently, in a traditional baking room, there are brackets for supporting bamboo poles. After manually fixing the roots of mature tobacco leaves to the bamboo poles, the bamboo poles full of tobacco leaves need to be placed on the brackets. When placing the bamboo poles, it is generally necessary to layer them. First, the top layer is filled manually, and then the upper, middle, and lower layers are filled in sequence, which is time-consuming, laborious, and costly. To explore ways to reduce labor and costs and improve quality and efficiency in the tobacco baking process, a fast, labor-saving, and automatic furnace loading method is selected to replace manual labor. Summary of the Utility Model

[0004] The utility model provides an automatic lifting device for a baking room to solve at least one of the above technical problems.

[0005] The technical solution adopted by the utility model is as follows:

[0006] An automatic lifting device for a baking room includes a support frame, and a plurality of lifting brackets are vertically slidably arranged in the support frame. A flexible traction part is fixedly connected between adjacent lifting brackets, and a lifting mechanism for controlling the lifting of the uppermost lifting bracket is arranged on the support frame.

[0007] Preferably, the lifting mechanism includes a rotating shaft, and a plurality of wire winding wheels are arranged at intervals along the axial direction of the rotating shaft. A steel wire rope is wound on the wire winding wheel, and the end of the steel wire rope is fixedly connected to the uppermost lifting bracket. A driving mechanism for driving the rotating shaft to rotate forward and backward is arranged on the support frame.

[0008] Preferably, the driving mechanism includes a driving motor and a gearbox. The gearbox has an input shaft and an output shaft. The output shaft is fixedly connected to the rotating shaft, and the input shaft is fixedly connected to the output end of the driving motor.

[0009] Preferably, two rotating shafts are symmetrically arranged in the same horizontal direction, and transmission sprockets are arranged on both rotating shafts. The two transmission sprockets are connected and driven by a chain.

[0010] Preferably, a vertical guide rail is arranged inside the support frame, and a guiding part that is slidably matched with the vertical guide rail is arranged on the side wall of the lifting bracket.

[0011] Preferably, the support frame is fixedly welded by a plurality of groups of vertical members and transverse members. The transverse members are welded to the upper and lower ends of the vertical members. The vertical members are made of I-beams, and the transverse members are made of square steel pipes. Reinforcing beams are connected between the transverse members in relative positions.

[0012] Preferably, the flexible traction part is a steel chain.

[0013] Preferably, the guiding part adopts pulleys or high molecular ethylene guiding blocks.

[0014] Preferably, a plurality of bearing support seats for supporting two rotating shafts are fixedly connected to the reinforcing beams and / or the transverse members.

[0015] Preferably, the hoisting bracket is welded by a plurality of groups of square steel pipes welded horizontally and vertically.

[0016] Due to the adoption of the above technical solutions, the beneficial effects obtained by the present utility model are as follows:

[0017] 1. In this application, through the setting of the hoisting bracket, the traditional method of hanging tobacco on a hanging rod can be replaced, and the bundled tobacco leaves can be directly hung on the hoisting bracket. It should be noted that before hanging the tobacco, the hoisting brackets are lowered to the lowest position through the lifting mechanism, so that there is a certain interval between the uppermost hoisting bracket and the adjacent hoisting brackets. The tobacco hanging worker can hang the tobacco leaves on the uppermost hoisting bracket through this interval. When the tobacco leaves on the uppermost hoisting bracket are hung, the hoisting bracket is lifted through the lifting mechanism, so that the uppermost hoisting bracket pulls the adjacent lower hoisting bracket to rise through the flexible traction part, so that there is a certain interval between the second hoisting bracket and the third hoisting bracket through the flexible traction part. Then the tobacco hanging worker repeats the tobacco hanging operation to hang the tobacco leaves on the second hoisting bracket. Similarly, when the tobacco leaves on the second hoisting bracket are hung, the first hoisting bracket is pulled to rise continuously through the lifting mechanism, so that the second hoisting bracket pulls the third hoisting bracket to rise through the flexible traction part, and the tobacco hanging worker continues to hang the tobacco leaves on the third hoisting bracket, and so on, until all the hoisting brackets are full of tobacco leaves. When the tobacco leaves are baked, the worker collects the tobacco leaves on the hoisting bracket from bottom to top. The upper hoisting bracket is lowered to an appropriate height through the lifting mechanism, so that the worker can collect the tobacco leaves layer by layer from bottom to top, greatly saving the steps of hanging tobacco and improving the efficiency of hanging tobacco. And through this application, the amount of labor can be significantly reduced, the labor intensity can be reduced, the cost can be reduced for the tobacco loading link, and the income of tobacco farmers can be increased.

[0018] 2. As a preferred embodiment of the present utility model, the driving mechanism drives the rotating shaft to rotate clockwise. The wire winding wheel rotates with the rotating shaft to wind the steel wire rope, and the uppermost lifting bracket is lifted by the traction of the steel wire rope. When the uppermost lifting bracket rises, the distance between it and the adjacent lower lifting bracket gradually increases. When the flexible traction part between the two lifting brackets is tightened, the distance between the two lifting brackets reaches the maximum value. At this time, the driving mechanism continues to drive the rotating shaft to rotate clockwise, and the second lifting bracket from the top starts to rise. When the flexible traction part between the second lifting bracket and the third lifting bracket is straightened, the distance between the second lifting bracket and the third lifting bracket reaches the maximum value, and so on, so as to complete the interval adjustment between several lifting brackets. When the lifting bracket needs to descend, the driving mechanism drives the rotating shaft to rotate counterclockwise, which is simple to operate and has good practicability.

[0019] 3. As a preferred embodiment of the present utility model, two rows of wire winding wheels can be symmetrically arranged by symmetrically arranging two rotating shafts. The steel wire ropes on the two rows of symmetrically arranged wire winding wheels can apply the same pulling force to both sides of the lifting bracket at the same time, so as to increase the stability of the lifting bracket during the lifting and lowering process. The synchronous rotation of the two rotating shafts can be realized through the transmission mode of the transmission sprocket and the chain, so as to ensure that the wire winding wheels on the two rotating shafts rotate at the same angle, and avoid the difference in the winding and unwinding distance of the steel wire rope, resulting in the side deviation of the uppermost lifting bracket.

[0020] 4. As a preferred embodiment of the present utility model, the lifting bracket can be guided and limited by the vertical guide rail and the guiding part, so as to increase the stability of the lifting bracket during the lifting and lowering process. Specifically, the guiding part adopts a pulley or a high molecular ethylene guiding block. The high molecular ethylene guiding block has good wear resistance and sliding guiding ability, which can reduce the frictional resistance between the lifting bracket and the vertical guide rail. At the same time, it can also greatly reduce the noise generated by the sliding between the lifting bracket and the vertical guide rail.

[0021] 5. As a preferred embodiment of the present utility model, the support frame is welded and fixed by several groups of vertical members and horizontal members. The horizontal members are welded to the upper and lower ends of the vertical members. After welding as shown in Figures 1 - 3 , the overall structure has good stability. The vertical members adopt I-beams, which can provide a stable support effect and form a vertical guide rail structure for limiting and guiding depending on the shape of the I-beam itself, so as to increase the stability of the lifting bracket during the lifting and lowering process. The horizontal members adopt square steel pipes, and reinforcing beams are connected between the horizontal members in the relative positions. The setting of the reinforcing beams can further increase the overall structural strength of the support frame.

[0022] 6. As a preferred embodiment of the present utility model, arranging and welding square steel pipes vertically and horizontally can not only increase the stability of the overall structure of the lifting bracket, but also increase the hanging positions of tobacco leaves, increase the hanging quantity of tobacco leaves on a single lifting bracket, improve the baking efficiency of tobacco leaves, and thus increase the production capacity.

[0035] Refer to Figures 1 - 4 , an automatic lifting device for a baking room, comprising a support frame 1, a plurality of lifting brackets 2 slidably arranged vertically within the support frame 1, a flexible traction part 201 fixedly connected between adjacent lifting brackets 2, and a lifting mechanism provided on the support frame 1 for controlling the lifting of the uppermost lifting bracket 2.

[0036] Those skilled in the art can understand that the support frame 1 is assembled inside the curing barn. By setting up the hoisting bracket 2, the traditional method of hanging tobacco on rods can be replaced, and the bundled tobacco leaves can be directly hung on the hoisting bracket 2. It should be noted that before hanging the tobacco, several hoisting brackets 2 are lowered to the lowest position through the lifting mechanism, so that there is a certain interval between the uppermost hoisting bracket 2 and the adjacent hoisting bracket 2. The tobacco hanging worker can hang the tobacco leaves on the uppermost hoisting bracket 2 through this interval. When the tobacco leaves on the uppermost hoisting bracket 2 are hung up, the hoisting bracket 2 is lifted through the lifting mechanism, so that the uppermost hoisting bracket 2 pulls up the adjacent lower hoisting bracket 2 through the flexible traction part 201, making there be a certain interval between the second hoisting bracket 2 and the third hoisting bracket 2 through the flexible traction part 201. Then the tobacco hanging worker repeats the tobacco hanging operation to hang the tobacco leaves on the second hoisting bracket 2. Similarly, when the tobacco leaves on the second hoisting bracket 2 are hung up, the first hoisting bracket 2 is pulled up continuously through the lifting mechanism, so that the second hoisting bracket 2 pulls up the third hoisting bracket 2 through the flexible traction part 201, and the tobacco hanging worker continues to hang the tobacco leaves on the third hoisting bracket 2, and so on until all the hoisting brackets 2 are filled with tobacco leaves. When the tobacco baking is completed, the worker collects the tobacco leaves on the hoisting bracket 2 from bottom to top. The upper hoisting bracket 2 is lowered to an appropriate height through the lifting mechanism, so that the worker can collect the tobacco leaves layer by layer from bottom to top, greatly saving the steps of hanging tobacco and improving the efficiency of hanging tobacco. And through this application, the labor amount can be significantly reduced, the labor intensity can be alleviated, the cost for the tobacco loading link can be reduced, and the income of tobacco farmers can be increased.

[0037] Specifically, the flexible traction part 201 is a steel chain, and the steel chain has stable tensile capacity.

[0038] As a specific implementation manner of the lifting mechanism in this application, referring to Figures 1 - 4 , the lifting mechanism includes a rotating shaft 3, and a plurality of wire winding wheels 301 are arranged at intervals along the axial direction of the rotating shaft 3. A steel wire rope 302 is wound around the wire winding wheel 301, and the end of the steel wire rope 302 is fixedly connected to the uppermost hoisting bracket 2. A driving mechanism for driving the rotating shaft 3 to rotate forward and backward is provided on the support frame 1.

[0039] When it is necessary to raise the lifting bracket 2, the driving mechanism drives the rotating shaft 3 to rotate clockwise. The wire winding wheel 301 rotates with the rotating shaft 3 to wind the steel wire rope 302, and the uppermost lifting bracket 2 is pulled up by the steel wire rope 302. When the uppermost lifting bracket 2 rises, the interval between it and the adjacent lower lifting bracket 2 gradually increases. When the flexible traction part 201 between the two lifting brackets 2 is tightened, the interval between the two lifting brackets 2 reaches the maximum value. At this time, the driving mechanism continues to drive the rotating shaft 3 to rotate clockwise, and the second lifting bracket 2 from top to bottom starts to rise. When the flexible traction part 201 between the second lifting bracket 2 and the third lifting bracket 2 is straightened, the interval between the second lifting bracket 2 and the third lifting bracket 2 reaches the maximum value, and so on, the interval adjustment between several lifting brackets 2 can be completed. It should be noted that the maximum interval between two adjacent lifting brackets 2 needs to be not less than the maximum length of the tobacco leaves to ensure that the lower end of the tobacco leaves will not be bent. When it is necessary to lower the lifting bracket 2, the driving mechanism drives the rotating shaft 3 to rotate counterclockwise, which will not be elaborated here.

[0040] Specifically, the driving mechanism includes a driving motor 4 and a gearbox 401. The gearbox 401 has an input shaft and an output shaft. The output shaft is fixedly connected to the rotating shaft 3, and the input shaft is fixedly connected to the output end of the driving motor 4. The setting of the driving motor 4 and the gearbox 401 facilitates the control of the forward and reverse rotation of the driving rotating shaft 3. It should be noted that the driving motor 4 uses a forward and reverse motor with the model 90YR120GY38, but it is not limited to this model.

[0041] As a preferred example of the above embodiment, refer to Figure 3 , two rotating shafts 3 are symmetrically arranged in the same horizontal direction. Transmission sprockets 303 are provided on both rotating shafts 3, and the two transmission sprockets 303 are connected and driven by a chain 3031. By symmetrically arranging the two rotating shafts 3, two rows of wire winding wheels 301 can be symmetrically arranged. The steel wire ropes 302 on the two rows of symmetrically arranged wire winding wheels 301 can apply the same pulling force to both sides of the lifting bracket 2 to increase the stability of the lifting bracket 2 during the lifting and lowering process. Through the transmission method of the transmission sprockets 303 and the chain 3031, the two rotating shafts 3 can rotate synchronously, thereby ensuring that the wire winding wheels 301 on the two rotating shafts 3 rotate at the same angle, and avoiding the difference in the winding and unwinding distances of the steel wire rope 302, resulting in the side deviation of the uppermost lifting bracket 2.

[0042] As a preferred embodiment of the support frame 1, refer to Figure 1 , a vertical guide rail 101 is provided inside the support frame 1, and a guiding part 202 that is slidably matched with the vertical guide rail 101 is provided on the side wall of the lifting bracket 2.

[0043] The guiding and limiting of the hoisting bracket 2 can be achieved through the vertical guide rail 101 and the guiding part 202, which increases the stability of the hoisting bracket 2 during the lifting process. Specifically, the guiding part 202 uses pulleys or high molecular ethylene guiding blocks. The high molecular ethylene guiding blocks have good wear resistance and sliding ability, which can reduce the frictional resistance between the hoisting bracket 2 and the vertical guide rail 101. At the same time, it can also greatly reduce the noise generated by the sliding between the hoisting bracket 2 and the vertical guide rail 101.

[0044] Among them, the support frame 1 is welded and fixed by several groups of vertical members and horizontal members. The horizontal members are welded to the upper and lower ends of the vertical members. After the horizontal members and the vertical members are welded as Figures 1 - 3 shown, the overall structure has good stability. The vertical members use I-beams. The I-beams can provide a stable support effect and, relying on the shape of the I-beams themselves, form a vertical guide rail 101 structure for limiting and guiding, increasing the stability of the hoisting bracket 2 during the lifting process. The horizontal members use square steel pipes, and a reinforcing beam is connected between the horizontal members in relative positions. Through the setting of the reinforcing beam, the overall structural strength of the support frame 1 can be further increased.

[0045] As a preferred example of the above embodiment, referring to Figures 1 - 4 , several bearing support seats 304 for supporting the two rotating shafts 3 are fixedly connected to the reinforcing beam and / or the horizontal members.

[0046] Through the setting of the bearing support seats 304, it is convenient to support the rotating shaft 3 and prevent the middle part of the rotating shaft 3 from bending and deforming due to the tensile force.

[0047] The hoisting bracket 2 is welded by several groups of square steel pipes welded horizontally and vertically in the horizontal direction. By arranging and welding the square steel pipes horizontally and vertically, the overall structure stability of the hoisting bracket 2 can be increased, and the hanging positions of the tobacco leaves can be increased, the hanging amount of the tobacco leaves on a single hoisting bracket 2 can be increased, the baking efficiency of the tobacco leaves can be increased, and thus the production capacity can be increased.

[0049] Each embodiment in this specification is described in a progressive manner. For the same or similar parts among the embodiments, reference can be made to each other. Each embodiment focuses on the differences from other embodiments.
