Description

Technical Field

[0001] This utility model relates to the field of edible fungi equipment, specifically to an automatic bagging mechanism. Background Technology

[0002] When cultivating edible fungi using plastic bags (also known as mushroom bags), the culture medium needs to be filled into the plastic bags. In the early days, the bagging process was generally done manually, which resulted in low bagging efficiency, easy contamination, and high labor intensity. Currently, bagging machines on the market use a spiral conveying mechanism composed of an auger, auger shaft, and motor power transmission components. The bag-filling and bag-opening device of the bagging machine is used to open the plastic bag and put it onto the discharge cylinder. Because plastic bags are soft, the existing bag-filling and bag-opening process is complicated. The existing bag-filling and bag-opening methods generally involve sucking the plastic bag open with a suction cup, fixing the bag opening inside the device through the bag-opening device, and then opening the bag opening through a vacuum suction cup, or using a complex claw assembly to open the entire bag before putting it into the discharge cylinder. The suction cup method is difficult to create a vacuum environment, which can lead to insufficient suction and failure to fully open the bag. The claw assembly is complex in structure and cumbersome in procedure, which greatly reduces work efficiency. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and provide an automatic bagging mechanism that is simple in structure, low in cost, easy to operate, and has high bag-filling efficiency.

[0004] To achieve the above objectives, the technical solution of this utility model is: an automatic bagging mechanism, including a mounting plate and a bag-supporting assembly, wherein a slide rail is mounted on the mounting plate, and the bag-supporting assembly is slidably connected to the slide rail via a transverse transmission mechanism, characterized in that: the bag-supporting assembly includes a component mounting plate and a movable bag-supporting claw, a curved groove is provided on the surface of the component mounting plate, the movable bag-supporting claw is slidably connected to the curved groove via a linkage mechanism, and a drive mechanism for pushing the movable bag-supporting claw to move is provided at the bottom of the component mounting plate.

[0005] The drive mechanism includes drive motors at both ends of the mounting plate of the split assembly and a first synchronous pulley. A second synchronous pulley is mounted on the motor shaft of the drive motor. The first and second synchronous pulleys are connected together by a synchronous belt. The movable support bag claw is connected to the synchronous belt.

[0006] The linkage mechanism includes a central vertical shaft, from top to bottom, a movable claw link, a fixed claw link, and a deep groove ball bearing. The movable claw link is connected to the movable claw of the movable support claw, and the fixed claw link is connected to the fixed claw of the movable support claw. One end of the deep groove ball bearing is in contact with the inner wall of the curved groove.

[0007] The movable claw of the movable support bag claw is connected to the synchronous belt via a synchronous belt pressure plate.

[0008] A guide rail is installed on one side of the component mounting plate, and the movable claw and fixed claw of the movable support bag claw are slidably connected to the guide rail by a slider.

[0009] Both the movable claw and the fixed claw have a support bag plate installed on the side facing the component mounting plate.

[0010] The movable claw includes a fixed arm and a movable arm, which are connected together by an adjusting screw.

[0011] A proximity switch is installed on one side of the drive motor.

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

[0013] 1. This utility model uses a movable claw to drive a connecting rod, which in turn drives a fixed claw to move the movable bag-holding claw. Because a curved groove is set in the component mounting plate, the movable claw connecting rod will move one step ahead of the fixed claw connecting rod. As a result, the movable claw and fixed claw of the movable bag-holding claw will open naturally during the forward movement. A single drive motor is used to achieve two different actions: movement and bag-holding. Compared with existing equipment, some parts are reduced, equipment costs are lowered, operation is more convenient, and bag-holding efficiency is also improved.

[0014] 2. This utility model utilizes a synchronous belt mechanism installed on the component mounting plate to drive the movement of the movable claw, resulting in a simpler overall structure, higher transmission efficiency, lower failure rate, and easier maintenance and installation.

[0015] 3. In this utility model, the distance between the movable claw and the fixed claw can be adjusted by adjusting the screw to adapt to different sizes of mushroom bags, making it more flexible to use. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] See Figures 1-6 An automatic bagging mechanism includes a mounting plate 1 and a bag-supporting assembly 2. A slide rail 3 is mounted on the mounting plate 1. The bag-supporting assembly 2 is slidably connected to the slide rail 3 via a transverse transmission mechanism. The bag-supporting assembly 2 includes a component mounting plate 4 and a movable bag-supporting claw 5. A bag-supporting piece 20 is mounted on the side of the movable claw 5 facing the component mounting plate 4, where the movable claw 16 and the fixed claw 17 are respectively mounted. A guide rail 19 is installed on one side of the component mounting plate 4. A curved groove 6 is provided on the surface of the component mounting plate 4. The curved groove 6 is composed of a combination of an arc-shaped short groove and a straight long groove. The movable support claw 5 is slidably connected to the curved groove 6 through a linkage mechanism 7. The linkage mechanism 7 includes a central vertical shaft 12. The central vertical shaft 12 is sequentially sleeved with a movable claw connecting rod 13, a fixed claw connecting rod 14, and a deep groove ball bearing 15 from top to bottom. The movable claw connecting rod 13 is connected to the movable claw 16 of the movable support claw 5. The movable claw 16 is slidably connected to the guide rail 19 through a slider. The movable claw 16 includes a fixed arm 21 and a movable arm 22. The fixed arm 21 and the movable arm 22 are connected together by an adjusting screw 23. The fixed claw connecting rod 14 is connected to the fixed claw 17 of the movable support claw 5. One end of the deep groove ball bearing 15 is in contact with the inner wall of the curved groove 6. A drive mechanism for pushing the movable support claw 5 to move is provided at the bottom of the component mounting plate 4.

[0025] The drive mechanism includes a drive motor 8 and a first synchronous pulley 9 at both ends of the split assembly mounting plate 4. A proximity switch 24 is provided on one side of the drive motor 8. A second synchronous pulley 10 is mounted on the motor shaft of the drive motor 8. The first synchronous pulley 9 and the second synchronous pulley 10 are connected together by a synchronous belt 11. The movable claw 16 of the movable support bag claw 5 is connected to the synchronous belt 11 through a synchronous belt pressure plate 18.

[0026] The working process of this utility model is as follows: When the bagging operation begins, the central vertical shaft 12 of the linkage mechanism 7 is located at the top of the arc-shaped short groove. At this time, the movable claw 16 of the movable bag-supporting claw 5 is in contact with the fixed claw 17, and the movable bag-supporting claw 5 is in a closed state. For details, please refer to [link to relevant documentation]. Figures 1-3 When bagging is required, the bag-supporting assembly 2 moves to the designated position on the slide rail 3 via the transverse transmission mechanism. Then, the motor shaft of the drive motor 8 rotates clockwise, which in turn drives the synchronous belt 11 to rotate clockwise. Since the movable claw 16 is connected to the synchronous belt 11 via the synchronous belt pressure plate 18, the movable claw 16 will move forward with the synchronous belt. The moving movable claw 16 will drive the central vertical shaft 12 to move forward along the curved groove 6 via the movable claw connecting rod 13, and the fixed claw connecting rod 14 will also rotate accordingly. Due to the special shape of the arc-shaped short groove at the front of the curved groove 6, the fixed claw 17 will remain stationary when the central vertical shaft 12 moves forward in the arc-shaped short groove. As a result, the movable bag-supporting claw 5 slowly opens. When the central vertical shaft 12 reaches the straight long groove, the fixed claw connecting rod 14 will also move forward with the central vertical shaft 12. When the central vertical shaft 12 reaches the end of the straight long groove, it will feel resistance, the drive motor 8 will stop rotating, and the movable bag-supporting claw 5 will reach the designated position, ready for bagging. See the specific state for details. Figures 4-6 After the bagging is completed, when the device returns to its original position, the motor shaft of the drive motor 8 rotates counterclockwise, and the central vertical shaft 12 moves backward along the straight long groove. When the central vertical shaft 12 reaches the connection point between the straight long groove and the arc-shaped short groove, the fixed claw 17 has returned to its original position. The subsequent process is that the movable claw 16 moves towards the fixed claw 17 during the movement of the central vertical shaft 12.

[0027] When changing to different sizes of mushroom bags, it is necessary to adjust the distance between the movable claw 16 and the fixed claw 17. This can be achieved by adjusting the angle of the movable arm 22 by adjusting the screw 23.
