Description

Technical Field

[0001] This utility model relates to the technical field of tobacco processing equipment, and in particular to a double-cylinder baling machine. Background Technology

[0002] In the tobacco leaf production and processing process, harvested tobacco leaves need to be compacted and packaged to reduce volume, improve storage space utilization, and reduce the risk of moisture, mold, and loss during storage and transportation. Existing tobacco leaf baling machines mostly require opening a rotating door for feeding, necessitating repeated opening and closing of the door. This process is not only cumbersome and inefficient, but also easily allows external dust and impurities to enter the baling chamber and contaminate the tobacco leaves. Therefore, a double-cylinder baling machine is proposed. Utility Model Content

[0003] The present invention aims to provide a double-cylinder baler, which simplifies the feeding process, reduces tobacco leaf loss, and is a highly safe tobacco leaf baling device, effectively solving the problems existing in the prior art.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: A double-cylinder baler includes a chassis mounted above a base plate, a drive box mounted on the base plate, and a rotating door mounted on the drive box. When the rotating door is closed, it forms a baling chamber with the chassis. A drive device is installed inside the chassis and drive box. A pressing head is connected to the drive head of the drive device. The drive device drives the pressing head to move up and down vertically, so as to apply pressure to the material in the baling chamber to compact it when the pressing head moves down. After the pressing head moves up to the initial position, the rotating door can be opened to remove the compacted material.

[0005] Furthermore, the driving device is a hydraulic cylinder or a pneumatic cylinder.

[0006] Furthermore, the base plate and the pressing head are provided with wooden boards for cushioning during pressing.

[0007] Furthermore, the drive box is equipped with a rotating door via hinges.

[0008] Furthermore, a mechanical locking mechanism is provided at the connection between the revolving door and the chassis. The locking mechanism includes a latch located at the free end of the revolving door and a latch located at the corresponding position on the chassis.

[0009] Furthermore, it also includes a safety interlock device, which includes a position sensor located on the top of the chassis and a controller electrically connected to the mechanical locking mechanism. When the pressure head does not move to the initial position, the controller locks the mechanical locking mechanism to prevent the revolving door from opening.

[0010] Compared with the prior art, this utility model has the following advantages: 1. By opening a feed port with a cover on the top or side of the machine, tobacco leaves can be filled into the baling chamber without opening the rotating door, simplifying the feeding process, avoiding tobacco leaf contamination and cumbersome operation caused by repeatedly opening and closing the rotating door, and improving baling efficiency; 2. Buffer wooden boards are set on the lower surface of the pressing head and the upper surface of the base plate. During the pressing process, the impact of the pressing head on the tobacco leaves can be buffered, reducing the breakage of tobacco fibers and the generation of dust, thus ensuring the quality of tobacco leaves. At the same time, the anti-slip texture of the wooden boards can prevent the tobacco leaves from sliding and ensure uniform compaction. 3. A safety interlocking device consisting of a position sensor and a controller is installed. When the pressure head fails to return to the initial position, the mechanical locking mechanism is automatically locked to prevent accidental opening of the rotating door and thus improve the safety of equipment operation. 4. The drive unit can be either a hydraulic cylinder or a pneumatic cylinder, which can be flexibly adapted according to the moisture content and fluffiness of the tobacco leaves. The low speed and high thrust of the hydraulic cylinder are suitable for tobacco leaves with high moisture content, while the fast return of the pneumatic cylinder is suitable for dry tobacco leaves, thus improving the adaptability of the equipment to tobacco leaves in different states.

Detailed implementation method: The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] like Figure 1-2 As shown, this utility model provides a double-cylinder baling machine, including a machine housing 4 disposed above a base plate 1, a drive box 2 disposed on the base plate 1, and a rotating door 3 disposed on the drive box 2. When the rotating door 3 is closed, it and the machine housing 4 enclose a baling chamber 5. A drive device 6 is disposed inside the machine housing 4 and the drive box 2. A pressing head 7 is connected to the drive head of the drive device 6. The drive device 6 drives the pressing head 7 to move up and down in the vertical direction, so as to apply pressure to the material in the baling chamber 5 to compact it when the pressing head 7 moves down. After the pressing head 7 moves up to the initial position, the rotating door 3 can be opened to remove the compacted material.

[0015] The system includes a housing 4 mounted above a base plate 1. A drive housing 2 is also mounted on the base plate 1. The drive housing 2 has a rotating door 3. When closed, the rotating door 3 not only forms a baling chamber 5 with the housing 4 to accommodate the tobacco leaves, but also prevents tobacco leaf debris from splashing during compaction, providing a safety protection function. A drive device 6 is installed inside the housing 4 and drive housing 2. This drive device 6 has stable power, and a pressing head 7 is connected to its drive head. The drive device 6 can drive the pressing head 7 to move smoothly up and down vertically. When the pressing head 7 moves downwards... It can apply uniform pressure to the tobacco leaves in the baling chamber 5, which can not only compact the tobacco leaves to significantly reduce their volume and improve the utilization rate of storage space, but also prevent the tobacco leaves from breaking, getting damp and moldy due to loose accumulation, effectively ensuring the integrity and quality of the tobacco leaves. After the baling head 7 moves upward to the initial position, the compacted tobacco leaves can be taken out by opening the rotating door 3. The compacted tobacco leaves have good shape, which is convenient for subsequent handling, stacking and transfer operations, reducing the loss of tobacco leaves in subsequent stages and further improving the overall efficiency of tobacco leaf processing.

[0016] The drive device 6 is a hydraulic cylinder or a pneumatic cylinder.

[0017] The drive device 6 is either a hydraulic cylinder or a pneumatic cylinder. If it is a hydraulic cylinder, its structure consists of a cylinder body, a sealed piston, and a piston rod. It relies on the inflow and outflow of hydraulic oil in the cylinder body to drive the piston movement. It has the characteristics of large output thrust, stable pressure, and precise adjustment. When it drives the pressing head 7 to move downward, it can apply continuous and uniform pressure to tobacco leaves with tough fibers and high moisture content, ensuring that the tobacco leaves have uniform density after compaction and are not easy to loosen. If it is a pneumatic cylinder, its structure includes a cylinder barrel, a pneumatic piston, and an inlet and outlet. It relies on the inflow and outflow of compressed air to drive the piston movement. It has the advantages of fast action response speed and high return efficiency. It is suitable for dry tobacco leaves with low loft and can quickly complete the up and down movement of the pressing head 7, shorten the single packing cycle time, and improve processing efficiency. Both drive devices 6 have their drive ends rigidly connected to the pressing head 7. The bottom of the pressing head 7 has anti-slip textures to reduce relative slippage when in contact with the tobacco leaves. After the pressing head 7 presses the tobacco leaves down to compact them, it returns to its initial position. Unlocking the rotating door 3 allows the formed tobacco leaf blocks to be removed. The formed tobacco leaf blocks facilitate subsequent grading, stacking, storage, and long-distance transportation, reducing tobacco leaf loss at each stage. The base plate 1 and the pressing head 7 are provided with wooden boards 8 for cushioning during pressing.

[0018] The bottom plate 1 is covered with wooden boards 8, and the bottom of the pressing head 7 is also fixed with wooden boards 8. The core function of these two wooden boards 8 is to provide cushioning during the pressing process. The drive device 6 inside the machine box 4 and drive box 2 is a hydraulic cylinder or air cylinder. Its drive end is rigidly connected to the pressing head 7. During operation, the drive device 6 can drive the pressing head 7 to move smoothly up and down in the vertical direction. When the pressing head 7 moves downward to apply pressure to the tobacco leaves in the packing chamber 5, the wooden boards 8 on the bottom plate 1 and the pressing head 7 can effectively alleviate the direct hard impact between the pressing head 7 and the tobacco leaves, and between the tobacco leaves and the bottom plate 1, to avoid the tobacco fiber breakage or excessive dust caused by pressure concentration. At the same time, it ensures that the tobacco leaves can still maintain good integrity during the process of being compacted to reduce volume and improve storage utilization. After the pressing head 7 moves upward to the initial position, the rotating door 3 can be opened to take out the compacted tobacco leaves. The compacted tobacco leaves are convenient for subsequent handling, stacking and transfer operations, reducing tobacco leaf loss in subsequent processing.

[0019] The drive box 2 is equipped with a rotating door 3 via a hinge 9; a mechanical locking mechanism 10 is provided at the connection between the rotating door 3 and the chassis 4. The locking mechanism includes a locking tongue located at the free end of the rotating door 3 and a latch located at the corresponding position of the chassis 4.

[0020] To ensure the stability of the packing chamber 5 during compression, a locking tongue is provided at the free end of the rotating door 3, and a locking buckle is fixedly installed on the housing 4 at the position corresponding to the locking tongue. The locking tongue and the locking buckle together form a mechanical locking mechanism 10. When the rotating door 3 is closed, the locking tongue can precisely engage with the locking buckle to achieve a tight lock between the rotating door 3 and the housing 4. This prevents the rotating door 3 from accidentally loosening or shifting due to the force applied by the drive device 6 during the compression process. At the same time, it ensures the airtightness of the packing chamber 5, prevents the debris generated during the compression process from overflowing, and also isolates external dust and impurities from entering the chamber and contaminating the tobacco leaves.

[0021] It also includes a safety interlock device, which includes a position sensor located on the top of the chassis 4 and a controller electrically connected to the mechanical locking mechanism 10. When the pressing head 7 does not move to the initial position, the controller locks the mechanical locking mechanism 10 to prevent the revolving door 3 from opening.

[0022] The equipment is also equipped with a safety interlock device, which consists of a position sensor installed on the top of the chassis 4 and a controller electrically connected to the mechanical locking mechanism 10. The position sensor can monitor the position of the pressing head 7 in real time. When the pressing head 7 has not returned to the initial position, the position sensor transmits a signal to the controller, which immediately locks the mechanical locking mechanism 10, preventing the rotating door 3 from opening. This prevents personnel from opening the door and touching the moving parts before the pressing head 7 has returned to its original position, thus avoiding accidents caused by premature removal of uncompressed tobacco leaves, which could lead to packaging failure. Only when the pressing head 7 moves to the initial position and the position sensor returns a normal signal will the controller unlock the mechanical locking mechanism 10. At this time, the rotating door 3 can be opened to remove the compacted tobacco leaves. The compacted tobacco leaves reduce the storage space occupied, reduce the risk of dampness and mold, and facilitate subsequent handling, stacking, and transfer, thereby improving the efficiency of tobacco leaf processing.

[0023] The operation process of this utility model of a double-cylinder baler is as follows: First, close the rotating door 3 to securely lock the mechanical locking mechanism 10, allowing the rotating door 3 and the machine housing 4 to form a complete baling chamber 5. At this time, the preset top feed inlet of the baling chamber 5 is in an open state, and there is no need to open the rotating door 3. Next, start the drive device 6 to drive the pressing head 7 to the highest position, leaving sufficient space for the tobacco leaves to be put in. Then, fill the chamber with the tobacco leaves evenly through the feed inlet of the baling chamber 5 to avoid the tobacco leaves from piling up and shifting. After feeding is completed, close the feed inlet and confirm the locking state of the mechanical locking mechanism 10 again. Start the drive device 6 to drive the pressing head 7 to move downward. During the process, the bottom plate 1 and the wooden board 8 on the pressing head 7 buffer the pressure, so that the pressure is evenly applied to the tobacco leaves to achieve compaction. After the tobacco leaves are compacted, the drive device 6 drives the pressing head 7 back to the initial highest position. The position sensor on the top of the machine housing 4 detects the signal that the pressing head 7 is in position and transmits it to the controller. After receiving the signal, the controller unlocks the mechanical locking mechanism 10, and finally opens the rotating door 3 to take out the compacted tobacco leaves.
