Description

Technical Field

[0001] The utility model relates to the technical field of tobacco, in particular to a conveying device for a tobacco-carrying trolley in a channel-type tobacco-curing room. Background Art

[0002] Traditional static intensive tobacco curing rooms are beginning to upgrade to assembly line channel tobacco curing rooms. The channel assembly line tobacco curing room adopts a step-by-step baking method in the baking channel. The tobacco-carrying trolley enters the baking channel and temporarily stops in the first area of ​​the channel. After the countdown of the stay time reaches 0, it moves forward to the second area of ​​the channel, and repeats this process until the tobacco-carrying trolley completes its stay in the last area of ​​the channel, then leaves the baking channel from the channel exit and completes tobacco leaf baking.

[0003] Ordinary channels use rails, and the smoke-carrying trolley enters from the channel entrance. The wheels of the trolley move forward along the channel track under the traction of the traction force. The front and rear trolleys are connected end to end in sequence. When towing is required, the traction rope is manually hung on the bottom of the trolley at the exit end, and the winch is started to pull the trolley at the exit end out of the baking channel. The connected smoke-carrying trolley at the back moves synchronously to the new channel area. The trolley pulled out completes the entire baking process, and the trolley pulled into the channel entrance at the same time starts baking in the first area. This dragging method has the following disadvantages: First, the wheels of the tobacco-carrying trolleys are easily deformed. Once the wheels of any trolley in a string of trolleys connected end to end in the channel are stuck in the channel track due to deformation, the entire series of trolleys will not be able to be dragged, and forced dragging may overturn and damage the baking room channel. The tobacco leaves in the entire row of trolleys cannot be baked in relays in each area according to the step-by-step process, resulting in bad tobacco losses and baking accidents; secondly, the tobacco-carrying trolley that has just entered the baking room must be manually connected with the tobacco-carrying trolley that is about to enter the second area, and then the towing rope must be manually hung on the bottom of the trolley at the exit end, and then the winch is started to drag the entire row of trolleys to the exit section for an area. The towed tobacco-carrying trolley needs to be manually disconnected from the trolley that has just entered the last area of ​​the channel, and the winch traction rope must be removed to prepare for the next stage of dragging. This method cannot achieve the fully automatic forward stepping of the tobacco-carrying trolley in the baking channel, affecting the baking efficiency.

[0004] Therefore, it is necessary to design a channel-type tobacco-curing room tobacco-carrying trolley conveying device to overcome the above problems. Utility Model Content

[0032] like Figures 1 to 4 As shown, the present embodiment provides a channel-type tobacco-carrying trolley conveying device for a tobacco-curing room, comprising: a first mounting frame 3a, a second mounting frame 3b, a first conveyor belt 4a, a second conveyor belt 4b, a driving mechanism 5 and a supporting roller 6.

[0033] The first mounting frame 3a and the second mounting frame 3b are arranged opposite to each other and are both mounted at the bottom of the tobacco curing room 1. The driving mechanism 5 includes a rotating shaft 51, a first gear 52, a second gear 53 and a driving motor 54.

[0034] The two ends of the two rotating shafts 51 are rotatably mounted on the first mounting frame 3a and the second mounting frame 3b respectively, and the two rotating shafts 51 arranged in parallel are respectively located at the input end and the output end of the tobacco curing room 1. The two rotating shafts 51 are installed at one end of the first mounting frame 3a and are coaxially fixed with the first gear 52, and are respectively located at the two ends of the first mounting frame 3a. The first conveyor belt 4a is wound around the first gear 52 at the two ends of the first mounting frame 3a, and the first conveyor belt 4a is provided with a tooth groove 41 meshing with the first gear 52; when the rotating shaft 51 rotates, the first gear 52 rotates accordingly, thereby driving the first conveyor belt 4a meshing therewith to move, so as to achieve the conveying purpose. Similarly, two rotating shafts 51 are mounted on one end of the second mounting frame 3b and are coaxially fixed with second gears 53, which are respectively located at both ends of the second mounting frame 3b. The second conveyor belt 4b is wound around the second gears 53 at both ends of the second mounting frame 3b. The second conveyor belt 4b is provided with tooth grooves 41 meshing with the second gears 53. Similarly, when the rotating shaft 51 rotates, the second gear 53 rotates accordingly, thereby driving the second conveyor belt 4b meshing therewith to move, thereby achieving the purpose of conveying. Figure 1 and Figure 3 shown.

[0035] At the same time, the driving motor 54 drives one of the rotating shafts 51. When the driving motor 54 is started, the rotating shaft 51 connected thereto will also rotate. In order to improve the stability and safety of the cigarette transporting trolley 2, two first gears 52 and two second gears 53 are coaxially mounted on both ends of the rotating shaft 51. The first conveyor belt 4a and the second conveyor belt 4b are both provided with tooth grooves 41 that match them. The force applied to the first conveyor belt 4a and the second conveyor belt 4b is more balanced, thereby ensuring the transport efficiency of the cigarette transporting trolley 2 on the first conveyor belt 4a and the second conveyor belt 4b.

[0036] In this embodiment, the driving mechanism 5 includes two driving motors 54, which are connected to the two rotating shafts 51 in a one-to-one driving manner. The two driving motors 54 are driven synchronously and in the same direction at both ends, and the driving force is large. The first conveyor belt 4a and the second conveyor belt 4b are subjected to balanced force, and the overall use is more reliable. At the same time, the first conveyor belt 4a and the second conveyor belt 4b are made of steel conveyor belts, which have high strength and good wear resistance.

[0037] At the same time, a plurality of supporting rollers 6 arranged in parallel along the conveying direction in the tobacco flue-curing room 1 are rotatably mounted on the first mounting frame 3a and the second mounting frame 3b. The supporting rollers 6 on the first mounting frame 3a are supported and abutted against the bottom of the conveying surface on the first conveyor belt 4a, and the supporting rollers 6 on the second mounting frame 3b are supported and abutted against the bottom of the conveying surface on the second conveyor belt 4b. The supporting rollers 6 on the first mounting frame 3a and the second mounting frame 3b are densely arranged, with a large load per unit area, and are more stable and efficient.

[0038] like Figure 1As shown, the device is installed on both sides of the air duct of the baking channel of the tobacco curing room 1, the conveying surface is at the same height as the ground at the entrance and exit of the channel, the drive motor 54 is distributed in the air duct position of the entrance and exit area of ​​the baking channel, and the mounting frame and the drive gear part are also distributed in the air duct on both sides of each area. At the same time, the input end and the output end of the first conveyor belt 4a and the second conveyor belt 4b are both provided with a guide rail 7 for guiding the tobacco-carrying trolley 2 into or out of the first conveyor belt 4a and the second conveyor belt 4b.

[0039] In order to ensure the stability of the guiding of the cigarette cart 2 by the guide track 7, a groove 71 is provided on it for guiding the movement of the wheels at the bottom of the cigarette cart 2. The wheels at the bottom of the cigarette cart 2 move in the groove 71 to ensure that it can move in a predetermined direction; at the same time, in order for the cigarette cart 2 to enter or move out of the first conveyor belt 4a and the second conveyor belt 4b, a guide part 72 is provided at one end of the guide track 7 connected to the first conveyor belt 4a or the second conveyor belt 4b, which is in the shape of a trumpet opening toward the first conveyor belt 4a or the second conveyor belt 4b, thereby improving the efficiency of the cigarette cart 2 entering and moving out.

[0040] In order to stabilize the cigarette trolley 2 on the first conveyor belt 4a or the second conveyor belt 4b, a limiting mechanism 8 is provided on the first mounting frame 3a and the second mounting frame 3b to prevent the cigarette trolley 2 from deflecting; wherein the limiting mechanism 8 includes a limiting seat 81, a limiting rod 82 and a limiting plate 83, the limiting seat 81 is installed on the first mounting frame 3a or the second mounting frame 3b and is located on one side of the first conveyor belt 4a or the second conveyor belt 4b, the limiting plate 83 is installed on the limiting seat 81 through the limiting rod 82, and the limiting plate 83 is located above the first conveyor belt 4a or the second conveyor belt 4b, as shown in FIG.

[0042] In other embodiments, the limit plate 83 can be movably installed on the limit seat 81 through the limit rod 82 in the direction of approaching and moving away from the limit seat 81. A buffer spring is connected between the limit plate 83 and the limit seat 81. The contact between the limit plate 83 and the cigarette trolley 2 will not affect collision or friction, and will not affect the position and moving direction of the cigarette trolley 2 on the first conveyor belt 4a and the second conveyor belt 4b by the limit plate 83. It is safe and stable, efficient and practical, simple in structure, and low in improvement cost.

[0043] During actual use, the tobacco-carrying trolley 2 fully loaded with tobacco leaves enters the passage along the guide track 7 at the entrance end of the passage of the baking room, the driving motor 54 is started synchronously, and the upper surfaces of the conveyor belts on both sides begin to move synchronously from the entrance to the exit, the wheels of the tobacco-carrying trolley 2 correspond to the conveyor belts, and when the two front wheels of the tobacco-carrying trolley 2 contact the moving conveying surface from the entrance guide track 7, the tobacco-carrying trolley 2 is driven by the conveying surface until the 22 rear wheels of the entire tobacco-carrying trolley also enter the conveying surface, and the entire tobacco-carrying trolley 2 will be carried forward; when the small tobacco-carrying trolley completes the relay baking of each area, the two front wheels of the tobacco-carrying trolley 2 move forward with the conveying surface and contact the guide track 7 on the ground of the passage exit, and the entire tobacco-carrying trolley 2 is moved and pushed into the guide track 7 on the ground of the exit until the tobacco-carrying trolley 2 leaves and all four wheels enter the guide track 7 outside the passage exit.

[0044] The device carries all the smoke-carrying carts 2 entering the baking room, and they move forward or stop synchronously. The smoke-carrying carts 2 do not need to be connected. After the smoke-carrying carts 2 complete baking in the entire area, they are automatically output from the baking channel, and the new smoke-carrying cart 2 is pushed to the entrance and will be transported into the baking channel; at the same time, according to the baking instructions, it automatically moves forward or stops to realize fully automatic assembly line baking.

[0045] The device has a simple structure and is easy to operate. It can efficiently and stably drive the tobacco-carrying trolley 2 to move in the baking channel of the tobacco-curing room 1 without manual connection and traction, and will not damage the tobacco-carrying trolley 2, thereby ensuring the safe and efficient completion of the tobacco-curing operation.
