Description

Technical Field

[0001] This utility model belongs to the technical field of tobacco curing equipment, specifically relating to an automatic weighing and turning tobacco loading device. Background Technology

[0002] Before tobacco leaves are placed in the curing barn, they need to be secured with woven tobacco sticks and clips. A large number of these sticks or clips are then hung in layers inside the barn for curing. This method is not only time-consuming and labor-intensive, but also results in inconsistent tobacco quality. Furthermore, the process of farmers climbing up and down the barn to load the sticks or clips sometimes presents safety risks. Existing technology includes a tobacco basket for loading tobacco outdoors. The basket is laid down during loading, filled with tobacco leaves, and then flipped over. Using this basket not only saves manpower and avoids the climbing involved in loading into the barn, but also improves tobacco quality and curing efficiency. While existing technologies utilize lifting devices to flip the baskets, most tobacco curing barns do not have these devices. Additionally, traditional lifting devices are primarily designed for vertical lifting and lack precise control mechanisms for the flipping action. Chinese patent CN 205093568U discloses an "Outdoor Tobacco Loading Device Based on Loose Leaf Insertion and Dense Baking," which uses a traction rope and controller to vertically lift the loose leaf tobacco loading basket and is equipped with rollers to enhance mobility. The lifting equipment and roller system improve loading efficiency. However, its complex structure, reliance on motor drive and signal line control, increases equipment cost and maintenance difficulty. Chinese patent CN 104872808 A discloses a "Tobacco Hanging Rack Tilting Platform," which uses a hydraulic cylinder to drive the L-shaped tilting platform main frame to achieve a 90° tilt of the tobacco hanging rack, reducing manual operation intensity. However, this device can only tilt the tobacco hanging rack, separating it from the tobacco loading function, resulting in a relatively limited functionality. Summary of the Invention

[0003] To address the aforementioned problems in the existing technology, this utility model provides an automatic weighing and turning tobacco loading device.

[0004] The purpose of this utility model is achieved in the following manner: an automatic weighing and turning tobacco loading device, comprising at least one turning platform and at least one tobacco loading weighing platform, wherein the tobacco basket can move between the turning platform and the tobacco loading weighing platform, the turning platform comprising a turning platform base frame and a turning mechanism, the turning mechanism comprising an L-shaped turning frame and a turning drive mechanism, the L-shaped turning frame being hinged to one side of the turning platform base frame, one end of the turning drive mechanism being hinged to the L-shaped turning frame and the other end being hinged to the turning platform base frame, the L-shaped turning frame being turned 90° under the drive of the turning drive mechanism; the tobacco loading weighing platform comprising a tobacco loading weighing platform base frame and a weighing sensor, the weighing sensor being provided on two opposite side frames of the tobacco loading weighing platform base frame.

[0005] The tilting table and the smoke weighing table are spaced apart.

[0006] At least one weighing platform for smoke is set between the two tilting tables.

[0007] One or two tilting tables are set between the two smoke-loading weighing platforms.

[0008] Multiple tobacco basket rollers are installed on the upper surface of both the tilting table base frame and the tobacco weighing table base frame, and the tobacco baskets roll on the tobacco basket rollers.

[0009] Limiting baffles are installed on one side of the base frame of the tilting table opposite to the L-shaped tilting frame, and on the side frame of the weighing table that is not adjacent to the base frame of the weighing table or the tilting table. Limiting baffles are installed on both sides of the weighing table base frame that are not adjacent to the base frame of the tilting table or the weighing table. Limiting baffles are installed on both sides of the base frame along the direction of movement of the tobacco basket.

[0010] The L-shaped tilting frame includes tilting plates and track grooves arranged perpendicularly to each other. There are two track grooves, and each track groove (1212) has a flared end.

[0011] Reinforcing ribs are installed between the track groove and the bottom support of the flip plate.

[0012] A tobacco leaf conveying device is installed on the side of the tobacco weighing platform, and the discharge port of the tobacco leaf conveying device is located above the tobacco weighing platform.

[0013] Compared to existing technologies, this utility model includes at least one tilting platform and at least one weighing platform for tobacco loading. The tobacco basket can move between the tilting platform and the weighing platform. The empty tobacco basket before loading and the tobacco basket after being filled with tobacco leaves are tilted on the tilting platform. Manual or automatic loading is performed on the weighing platform, and the weight is measured using a weighing sensor on the base of the weighing platform to control the amount of tobacco loaded. Combining the tilting and loading functions improves the degree of automation, reduces manual labor, and increases work efficiency. Attached Figure Description

[0015] Figure 2 This is another structural schematic diagram of the present invention.

[0016] Figure 3 This is a structural schematic diagram of the present invention excluding the wire mesh cage.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention. After reading the contents of the present invention, those skilled in the art can make various modifications or alterations to the present invention, and these equivalent forms also fall within the scope defined by the present invention.

[0019] like Figure 1 , Figure 4 As shown, an automatic weighing and tilting tobacco loading device includes at least one tilting platform 1 and at least one tobacco loading weighing platform 2. The tobacco basket can move between the tilting platform 1 and the tobacco loading weighing platform 2. The tilting platform 1 includes a tilting platform base 11 and a tilting mechanism 12. The tilting mechanism 12 includes an L-shaped tilting frame 121 and a tilting drive mechanism 122. The L-shaped tilting frame 121 is hinged to one side of the tilting platform base 11. One end of the tilting drive mechanism 122 is hinged to the L-shaped tilting frame 121, and the other end is hinged to the tilting platform base 11. The L-shaped tilting frame 121 is tilted 90° under the drive of the tilting drive mechanism 122. The tobacco loading weighing platform 2 includes a tobacco loading weighing platform base 21 and a weighing sensor 22. The weighing sensor 22 is provided on two opposite side frames of the tobacco loading weighing platform base 21.

[0020] The working process of the device is illustrated by taking a flipping table 1 and a tobacco weighing table 2 as an example: The empty tobacco basket 3 is pushed onto the L-shaped flipping frame 121 on the side of the flipping table 1. It is flipped 90° by the flipping drive mechanism 122 and placed horizontally on the flipping table 1. Then the empty tobacco basket 3 is pushed to the tobacco weighing table 2 for filling with tobacco. The amount of tobacco is monitored by the weighing sensor 22 on the base frame 21 of the tobacco weighing table. After the tobacco is filled, pins can be inserted directly on the tobacco weighing table 2 to fix the tobacco leaves. Alternatively, the tobacco basket 3 filled with tobacco leaves can be pushed back onto the flipping table 1 and pins can be inserted on the flipping table 1. After the tobacco leaves are fixed, the tobacco basket 3 is flipped 90° by the flipping mechanism 12 to adjust it from a horizontal to a vertical standing state. Then it is pushed into the curing room for curing.

[0021] Furthermore, while tobacco loading can be done manually, to improve automation and reduce manual labor, it can also be done using a tobacco leaf conveying device. The feeding end of the conveying device is raised, allowing the tobacco leaves to fall from above into the tobacco basket on the weighing platform 2. The tobacco leaf conveying device can be a belt conveyor or a chain conveyor.

[0022] The pin insertion process can be performed manually or with the aid of an automatic pin insertion machine.

[0023] Furthermore, the number of the flipping table 1 and the weighing table 2 can be adjusted appropriately based on the time for loading the smoke, the time for inserting the needle, and the available space.

[0024] In one scenario, where space permits, the turning table 1 and the tobacco loading and weighing table 2 are set up alternately, which is highly efficient and allows for the simultaneous loading and turning of multiple tobacco baskets.

[0025] In another scenario, one or two tilting platforms 1 are set between the two tobacco weighing platforms 2. Both empty and full tobacco baskets are tilted via the one or two tilting platforms 1 in the middle. Since the tilting speed is relatively fast and the tobacco loading time is slower than the tilting speed, two tobacco weighing platforms 2 can be configured with one tilting platform, saving space and allowing two tobacco baskets to work simultaneously, thus improving work efficiency.

[0026] Another situation, such as Figure 2 , Figure 3 As shown, a weighing platform 2 for filling cigarettes is set between two tilting tables 1. The cigarette basket 3 is flipped onto the worktable from one tilting table 1, filled and weighed in the middle, and then flipped off the worktable from the other tilting table 1, in an assembly line operation. If automatic filling and manual pin insertion are used, the filling speed is faster than pin insertion, so the number of weighing platforms 2 for filling cigarettes between the two tilting tables 1 can be increased.

[0027] To ensure the effective fixation of the tobacco leaves by the needles, the needles are generally quite long and extend beyond the tobacco basket. After the needles are inserted, the movement of the tobacco basket between the turning table 1 and the tobacco weighing table 2 is restricted. In addition, since the force used to insert the needles is relatively large, the weighing sensor 22 is easily damaged. Therefore, it is best to perform the needle insertion operation on the turning table 1.

[0028] Furthermore, in order to reduce the motion resistance between the tobacco basket turning platform 1 and the tobacco weighing platform 2, multiple tobacco basket support rollers 4 are provided on the upper surfaces of the turning platform base frame 11 and the tobacco weighing platform base frame 21, and the tobacco basket 3 rolls on the tobacco basket support rollers 4.

[0029] Furthermore, to prevent the tobacco basket from tilting, a limiting baffle 5 is installed on the side of the rotating platform base 11 opposite to the L-shaped rotating frame. A limiting baffle 5 is also installed on the side of the tobacco weighing platform base 21 that is not adjacent to the rotating platform base 11 or the rotating platform base 11. Limiting baffles 5 are also installed on the side of the tobacco weighing platform base 21 that is not adjacent to the rotating platform base 11 or the tobacco weighing platform base 21. Limiting baffles 5 are installed on both sides of the side of the tobacco basket along the direction of movement.

[0030] The L-shaped tilting frame 121 includes tilting plates 1211 and track grooves 1212 arranged perpendicularly to each other. The tilting plate 1211 includes at least two horizontal supports and at least two vertical supports. To improve the stability of the structure, a third horizontal support is added between the two horizontal supports, and one or two more vertical supports are added between the third horizontal support and the two vertical supports. One end of the tilting drive mechanism is hinged to the third horizontal support located in the middle of the tilting plate 1211. The track grooves 1212 facilitate the direct pushing of cigarette baskets with wheels at the bottom into the L-shaped tilting frame 9, reducing the use of forklifts and improving operational flexibility. There are two track grooves 1212, and each track groove 1212 has a flared end 1213 to facilitate the adjustment of the wheels at the bottom of the cigarette basket so that it can smoothly enter the track groove 1212.

[0031] A reinforcing rib (not shown in the figure) is provided between the bottom support of the track groove 1212 and the flip plate 1211.

[0032] The tilting drive mechanism is a hydraulic cylinder, pneumatic cylinder, or electric push rod, with hydraulic cylinders preferred because they typically have greater thrust, provide stable output, have high environmental adaptability, and are suitable for applications requiring high loads. In addition, hydraulic cylinders are relatively easy to maintain, have a relatively stable structure, a low failure rate, and low long-term operating costs.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
