Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, and in particular to a tobacco leaf compaction and bundling device. Background Technology

[0002] A tobacco leaf compaction and baling device is a device that compacts and bales cured tobacco leaves, compressing loose tobacco leaves into compressed packages that are easy to transfer.

[0003] Patent CN217089542U discloses a tobacco leaf pre-inspection and baling device. It includes a baling frame with a hinged upper cover plate, a sliding push plate inside the baling frame, and a pushing mechanism between the push plate and the baling frame. The pushing mechanism drives the push plate to slide within the baling frame. Using this patent, one end of a binding rope is fixed to the baling frame, and the other end is fixed to the push plate. After compression, the binding rope is pulled tight to perform baling. However, the above technical solution still has some shortcomings in actual use. Because the binding rope used in the above technical solution is close to the tobacco leaf, it is difficult to pull the binding rope when the tobacco leaf is compressed, and excessive force can cause damage to the tobacco leaf. After loosening the baling, the compressed tobacco leaf springs back, resulting in loose baling.

[0004] Therefore, there is a need for a tobacco leaf compaction and bundling device that allows the binding rope to be easily pulled when the tobacco leaves are compressed. Summary of the Invention

[0005] To overcome the problem of difficulty in pulling the binding rope when the tobacco leaves are compressed in the above-mentioned technical solutions, the present invention adopts the following technical solution: a tobacco leaf compaction and bundling device, including a frame, an upper cover plate hinged to one side of the top of the frame, a compression chamber formed between the frame and the upper cover plate, a pushing mechanism provided on the frame on one side of the compression chamber, a push plate provided at the top of the movable push rod of the pushing mechanism, the pushing mechanism being used to drive the push plate to slide in the compression chamber, a support plate provided on the frame on the other side of the compression chamber, and vertical rope guide grooves corresponding to the push plate and the support plate being provided, the binding rope being able to move up and down through the rope guide grooves.

[0006] As an improvement to the above solution, the frame and the top cover plate at the bottom of the compression chamber are provided with rope grooves that are vertically connected to the position of the rope groove. The binding rope can move in the rope groove, and there should be no horizontal structure in the rope groove. The tobacco leaves can be bound without opening the top cover plate.

[0007] As an improvement to the above solution, the opening and closing end of the upper cover plate is provided with a locking mechanism for locking the upper cover plate onto the frame.

[0008] As an improvement to the above solution, the pushing mechanism is a cylinder, a hydraulic cylinder, or an electric movable push rod. To increase the space of the compression chamber, the pushing mechanism is set on the outside of the frame, with its movable end facing the compression chamber, and the movable push rod of the pushing mechanism moves inside the compression chamber.

[0009] As an improvement to the above solution, the frame is also equipped with a controller for controlling the pressure, speed and switching of the jacking mechanism.

[0010] As an improvement to the above solution, the frame is also hinged with a side cover plate that can be opened and closed to cover both sides of the compression chamber.

[0011] Compared with the prior art, the present invention has the following technical effects:

[0012] 1. By setting vertical rope guide grooves at the corresponding positions of the push plate and the load-bearing plate, the binding rope can still move up and down through the rope guide groove when the tobacco leaves are compressed, avoiding damage to the outer tobacco leaves caused by pulling the binding rope too hard, and easily completing the binding operation of the tobacco leaves.

[0013] 2. The rope grooves, which are vertically connected to the rope guide grooves on the bottom frame and the top cover of the compression chamber, allow for the binding of tobacco leaves without opening the top cover, thus avoiding loose binding caused by the tobacco leaves springing back after the top cover is opened. In addition, the operator can directly observe the condition of the tobacco leaves in the compression chamber through the rope grooves on the top cover, making it easier to make timely adjustments.

A support plate-4 is provided on the frame-1 on the other side of the compression chamber-6. Vertical rope grooves-31 with corresponding positions are provided on the push plate-3 and the support plate-4, and the binding rope-8 can move up and down through the rope groove-31.

[0021] Specifically, the frame-1 at the bottom of the compression chamber-6 and the upper cover plate-5 are provided with a rope groove-11 that is vertically connected to the position of the rope groove-31. The binding rope-8 can move in the rope groove-11, and there cannot be any transverse structure in the rope groove-11.

[0022] Specifically, the opening and closing end of the upper cover plate-5 is provided with a locking mechanism-51, which is used to lock the upper cover plate-5 onto the frame-1.

[0023] Specifically, the pushing mechanism-2 is a cylinder, a hydraulic cylinder, or an electric movable push rod-21. The pushing mechanism-2 is located on the outside of the frame-1, with its movable end facing the compression chamber-6. The movable push rod-21 of the pushing mechanism-2 moves within the compression chamber-6.

[0024] Specifically, the frame-1 is also equipped with a controller for controlling the pressure, speed and switching of the pushing mechanism-2.

[0025] Specifically, the frame-1 is also hinged with a side cover plate-9 that can be opened and closed to cover both sides of the compression chamber-6.
