Description

Technical Field

[0001] This utility model relates to the field of vacuum packaging machine technology, specifically a vacuum packaging machine for traditional Chinese medicine materials. Background Technology

[0002] A vacuum packaging machine for Chinese medicinal herbs is a type of mechanical equipment specifically designed for packaging Chinese medicinal herbs. It uses a vacuum process to package the herbs in specific bags to extend their shelf life and maintain their medicinal efficacy.

[0003] Modern vacuum packaging machines also include conveyor belts, which serve as the machine's worktable and conveying device. The conveyor belt transports the items to be packaged from one end to the other, facilitating subsequent vacuuming and sealing processes. Conveyor belts typically have baffles to position the packaging bags, ensuring they remain in the correct position during transport for easy sealing. To improve the applicability of vacuum packaging machines, the baffles on the conveyor belt are often adjustable to accommodate different bag sizes. However, since multiple sets of baffles are often installed on the conveyor belt, and adjustments are mostly done manually, this significantly increases the operator's workload. Furthermore, manually adjusting the baffles takes time, which can delay the entire packaging process and reduce production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum packaging machine for traditional Chinese medicine materials to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A vacuum packaging machine for traditional Chinese medicine includes a support frame and a machine body. The machine body is located on top of the support frame and is equipped with a conveyor belt for conveying materials. A vacuum packaging mechanism is vertically mounted on the machine body. The conveyor belt is equipped with multiple positioning structures, each positioning structure including a limiting placement plate and a positioning frame. The positioning frame is fixedly mounted on the conveyor belt. The conveyor belt is equipped with a moving mechanism for moving the limiting placement plate. The moving mechanism includes a frame and a connecting belt. The conveyor belt is equipped with multiple sets of frames that can cooperate with each other.

[0007] Preferably, the frame has a rotatable rod inside, on which a take-up roller is fixedly mounted. Two sets of vertically parallel take-up rollers can cooperate with each other. One end of the take-up roller is fixedly connected to the connecting belt. A connector is detachably mounted on the connecting belt, and the connector is fixedly connected to the limiting plate by bolts.

[0008] Preferably, a first gear is fixedly installed on the rod, a motor is fixedly installed inside the frame, and a second gear is fixedly installed at the output end of the motor, with the second gear meshing with the first gear.

[0009] Preferably, the frame is rotatably provided with guide rollers for limiting and guiding the connecting strip during the winding process.

[0010] Preferably, the frame is internally fixedly provided with multiple sets of electric telescopic rods, the output end of which is provided with a mounting plate, and the mounting plate is externally fixedly provided with a positioning component that can cooperate with the take-up roller.

[0011] Preferably, the side of the positioning member that contacts the outside of the connecting belt is fixedly provided with an anti-slip rubber pad.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, equipped with a frame and connecting belt, allows the motor to rotate when the operator starts it. The motor's output drives gear two to rotate, which meshes with gear one, transmitting power to the rod. The rod's rotation further drives two sets of winding rollers (vertically parallel) fixed on it to rotate. These two sets of winding rollers operate in opposite states: one set performs winding, while the other releases, thus achieving effective management of the connecting belt. During the winding and releasing process, guide rollers limit and guide the connecting belt, ensuring it moves smoothly along a predetermined path and avoiding deviation or jamming. As the winding and releasing rollers work, the connecting belt is pulled and connected to the limiting placement plate via a connector, enabling the limiting placement plate to move. The movement of multiple sets of connecting belts causes multiple sets of limiting placement plates on the conveyor belt to adjust their positions, allowing operators to flexibly adjust the position of the limiting placement plates according to different sizes of packaging bags, greatly improving operational convenience and packaging flexibility.

[0014] 2. This utility model, by installing an electric telescopic rod and a positioning component, allows the operator to activate the electric telescopic rod after the connecting belt position is adjusted. The telescopic movement of the electric telescopic rod drives the mounting plate and its positioning component to move. As the positioning component moves, it gradually comes into contact with and tightly engages with the take-up roller, achieving precise positioning of the take-up roller. Once the positioning component is tightly engaged with the take-up roller, the electric telescopic rod stops its telescopic movement, completing the positioning process. Through precise positioning and fixing, the connecting belt on the take-up roller is prevented from loosening during long-term use, thus ensuring the stability and accuracy of the limiting placement plate.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4A vacuum packaging machine for traditional Chinese medicine includes a support frame 1 and a machine body 2. The machine body 2 is located on top of the support frame 1. A conveyor belt 3 for conveying materials is installed on the machine body 2. A vacuum packaging mechanism 4 is vertically mounted on the machine body 2. The conveyor belt 3 is equipped with multiple positioning structures, each including a limiting placement plate 6 and a positioning frame 5. The positioning frame 5 is fixedly mounted on the conveyor belt 3. A moving mechanism for moving the limiting placement plate 6 is installed on the conveyor belt 3. The moving mechanism includes a frame 7 and a connecting belt 8. Multiple sets of frames 7 that can cooperate with each other are installed on the conveyor belt 3. The support frame 1 supports the main structure of the entire vacuum packaging machine, and the machine body 2 is located on top of the support frame 1. The core component of the vacuum packaging machine is the conveyor belt 3, which is mounted on the machine body 2 and used to transport packaging bags containing traditional Chinese medicine herbs. The vacuum packaging mechanism 4 is vertically mounted on the machine body 2 and is used to vacuum package the packaging bags at specific positions on the conveyor belt 3. The operator places the packaging bags containing the herbs using the limiting placement plate 6. After placement, the positioning frame 5 positions the packaging bags precisely on the conveyor belt 3. The conveyor belt 3 then starts, transporting the positioned packaging bags to the bottom of the vacuum packaging mechanism 4. When the packaging bag reaches the predetermined position, the vacuum packaging mechanism 4 descends and vacuum-packs the bag. After vacuum packaging, the conveyor belt 3 continues to transport the packaged bag to the output end. Through the installation of the frame 7 and the connecting belt 8, as the operator starts the motor 13, the motor 13 begins to rotate. The output end of the motor 13 drives the gear 14 to rotate. The gear 14 meshes with the gear 12, transmitting power to the rod 10. The rod 10 rotates, and the rotation of the rod 10 further drives the two sets of winding rollers 11 (vertically parallel) fixed on it to rotate. The working states of these two sets of winding rollers 11 are opposite, that is, one set performs the winding action, while the other set performs the winding action. The release action enables effective management of the connecting belt 8. During the process of winding and releasing the connecting belt 8, the guide roller 15 limits and guides the connecting belt 8 to ensure that the connecting belt 8 can move smoothly along the predetermined path and avoid deviation or jamming. With the winding and releasing action of the winding roller 11, the connecting belt 8 is pulled and then connected to the limiting placement plate 6 through the connector 9, realizing the movement of the limiting placement plate 6. The movement of multiple sets of connecting belts 8 drives the position adjustment of multiple sets of limiting placement plates 6 on the conveyor belt 3, so that the operator can flexibly adjust the position of the limiting placement plate 6 according to the packaging bags of different sizes, which greatly improves the convenience of operation and the flexibility of packaging.

[0022] Please see Figure 2 and Figure 3Inside the frame 7, a rod 10 is rotatably mounted. A take-up roller 11 is fixedly mounted on the rod 10, and two sets of vertically parallel take-up rollers 11 can cooperate with each other. One end of the take-up roller 11 is fixedly connected to one end of the connecting belt 8. A connector 9 is detachably mounted on the connecting belt 8 and is fixedly connected to the limiting plate 6 by bolts. A gear 12 is fixedly mounted on the rod 10. Inside the frame 7, a motor 13 is fixedly mounted. A gear 14 is fixedly mounted at the output end of the motor 13, and the gear 14 meshes with the gear 12. Inside the frame 7, a guide roller 15 is rotatably mounted to limit and guide the connecting belt 8 during the winding process. When the operator starts the motor 13, the motor 13 begins to rotate. The output end of the motor 13 drives the gear 14 to rotate. The gear 14 meshes with the gear 12, transmitting power to the rod 10, causing the rod 10 to rotate. The rotation of the rod 10 further drives the two sets of take-up rollers 11 (vertically parallel) fixed on it to rotate. The working states of these two sets of take-up rollers 11 are opposite, that is, one set performs a take-up action, while the other set performs a release action, thereby achieving effective management of the connecting belt 8. During the process of one set taking up and one set releasing the connecting belt 8, the guide roller 15 limits and guides the connecting belt 8 to ensure that the connecting belt 8 can move smoothly along the predetermined path and avoid deviation or jamming. With the take-up and release actions of the take-up rollers 11, the connecting belt 8 is pulled and then connected to the limiting placement plate 6 through the connector 9, realizing the movement of the limiting placement plate 6. The movement of multiple sets of connecting belts 8 drives the multiple sets of limiting placement plates 6 on the conveyor belt 3 to adjust their positions, so that the operator can flexibly adjust the position of the limiting placement plate 6 according to the packaging bags of different sizes, which greatly improves the convenience of operation and the flexibility of packaging.

[0023] Please see Figure 3 and Figure 4The frame 7 has multiple sets of electric telescopic rods 16 fixedly installed inside. Each electric telescopic rod 16 has a mounting plate 17 at its output end. A positioning element 18 that cooperates with the take-up roller 11 is fixedly installed on the outside of the mounting plate 17. An anti-slip rubber pad 19 is fixedly installed on the side of the positioning element 18 that contacts the outside of the connecting belt 8. The electric telescopic rods 16, through their extension and retraction, drive the mounting plate 17 and the positioning element 18 to move. The mounting plate 17 serves as the mounting base for the positioning element 18 and moves with the extension and retraction of the electric telescopic rods 16. The positioning element 18 is used to precisely position the take-up roller 11 under the drive of the electric telescopic rods 16. The anti-slip rubber pad 19 increases the friction between the positioning element 18 and the connecting belt 8, preventing the connecting belt 8 from sliding or shifting during movement. The positioning effect of the positioning component 18 is improved. When the equipment is not started, the electric telescopic rod 16 is in the retracted state, and the mounting plate 17 and the positioning component 18 on it do not contact the take-up roller 11. After the position of the connecting belt 8 is adjusted, the operator starts the electric telescopic rod 16. The telescopic action of the electric telescopic rod 16 drives the mounting plate 17 and the positioning component 18 on it to move. As the positioning component 18 moves, it gradually comes into contact with the take-up roller 11 and fits tightly, realizing the precise positioning of the take-up roller 11. When the positioning component 18 fits tightly with the take-up roller 11, the electric telescopic rod 16 stops telescopic action, completing the positioning process. Through precise positioning and fixing, the connecting belt 8 on the take-up roller 11 is prevented from loosening during long-term use, thereby ensuring the stability and accuracy of the limit placement plate 6.

[0024] Working principle: The operator starts motor 13, which rotates. The output of motor 13 drives gear 14 to rotate, which meshes with gear 12, transmitting power to rod 10. Rod 10 rotates, further driving the two sets of take-up rollers 11 (vertically parallel) fixed on it to rotate. The two sets of take-up rollers 11 have opposite working states: one set performs a take-up action, while the other set performs a release action, thus achieving effective management of the connecting belt 8. During the process of one set taking up and the other releasing the connecting belt 8, guide roller 15 limits and guides the connecting belt 8, ensuring that the connecting belt 8 can move smoothly along the predetermined path and avoid deviation or jamming. With the take-up and release actions of the take-up rollers 11, the connecting belt 8 is pulled and then connected to the limiting placement plate 6 through the connector 9, realizing the movement of the limiting placement plate 6. The movement of multiple sets of connecting belts 8 drives the position adjustment of multiple sets of limiting placement plates 6 on the conveyor belt 3, allowing operators to flexibly adjust the position of the limiting placement plates 6 according to different sized packaging bags, greatly improving the convenience of operation and the flexibility of packaging. After the position of the connecting belts 8 is adjusted, the operator starts the electric telescopic rod 16. The extension and retraction of the electric telescopic rod 16 drives the mounting plate 17 and its positioning parts 18 to move. As the positioning parts 18 move, they gradually come into contact with and tightly cooperate with the winding roller 11, achieving precise positioning of the winding roller 11. When the positioning parts 18 are tightly cooperated with the winding roller 11, the electric telescopic rod 16 stops its extension and retraction, completing the positioning process. Through precise positioning and fixing, the connecting belts 8 on the winding roller 11 are prevented from loosening during long-term use, thus ensuring the stability and accuracy of the limiting placement plates 6.
