[0025] 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.

[0026] Please see Figure 1-5 The present invention provides the following technical solution: an automatic dough feeding device for a glutinous rice ball production line, comprising: a conveyor 10, a glutinous rice ball machine 11 and a support frame 12. The support frame 12 is installed at both ends of the conveyor 10. A discharge port is provided on one side of the conveyor 10 at intervals. The inlet and outlet of the glutinous rice ball machine 11 correspond to each other, so that the dough on the conveyor 10 can fall onto the glutinous rice ball machine 11 through the discharge port.

[0027] The support frame 12 is equipped with a lever mechanism. A pusher plate 13 is installed on the side of the lever mechanism facing the discharge port. The pusher plate 13 has an L-shaped plate structure. A connecting beam 32 is installed at the bottom of the pusher rod 22. The pusher plate 13 is connected to the connecting beam 32 by screws. It can effectively scoop up the dough on the conveyor 10 and push it to the discharge port to ensure that the dough is fed evenly.

[0028] The support frame 12 includes a U-shaped frame 17 fixedly installed at the discharge port of the conveyor 10 with a bottom opening and a support rod 18 installed on the top of the conveyor 10. The U-shaped opening of the U-shaped frame 17 corresponds to the discharge port. A connecting plate 19 is installed between the U-shaped frame 17 and the support rod 18. A drive groove 20 that runs vertically through the connecting plate 19 is provided on the connecting plate 19. The lever mechanism is rotatably arranged inside the drive groove 20.

[0029] Please see Figure 3 and Figure 5The lever mechanism includes a connecting rod 21 and a dial rod 22 disposed inside the drive groove 20. The top of the dial rod 22 is fixedly connected to the bottom of the connecting rod 21. The connecting rod 21 is connected to the drive component. The angle between the bottom of the connecting rod 21 and the top of the dial rod 22 is greater than 120 degrees. A rotating shaft 23 is rotatably installed at the connection between the connecting rod 21 and the dial rod 22. UC bearing seats 24 are installed at both ends of the connecting plate 19. UC bearings 25 are installed inside the UC bearing seats 24. The rotating shaft 23 rotatably passes through the connecting plate 19 at both ends and is connected to the UC bearings 25.

[0030] UC bearing housings are widely used in the machinery industry, characterized by their compact structure, easy installation, and high load-bearing capacity. These housings are typically made of cast iron or steel and can withstand large axial and radial loads.

[0031] Under the action of the driving component, the connecting rod 21 can swing back and forth around the rotating shaft 23, thereby driving the dough-pulling rod 22 to swing back and forth. The angle between the bottom of the connecting rod 21 and the top of the dough-pulling rod 22 is greater than 120 degrees, which allows the dough-pulling rod 22 to swing in an arc under the action of the connecting rod 21, realizing the continuous action of scooping up the dough from the conveyor 10 and moving it to the discharge port. With the rotating shaft 23 as the fulcrum, the lever principle drives the dough-pulling rod 22 to swing back and forth, thereby realizing the uniform movement of the dough.

[0032] A drive component is provided on the support frame 12. The drive component is connected to the lever mechanism. The drive component is used to drive the lever mechanism to make an arc swinging motion in the direction of the discharge port, thereby feeding the dough into the glutinous rice ball machine 11. The drive component is a drive cylinder 26 fixedly installed on the U-shaped frame 17. A joint bearing 27 is installed on the telescopic end of the drive cylinder 26. A connecting groove 28 that runs through the left and right sides is opened on the connecting rod 21. A through hole that runs through the front and back is opened on the connecting rod 21. A pin 29 is inserted into the through hole. One end of the pin 29 inserted into the connecting groove 28 is connected to the joint bearing 27, thereby realizing the function of the drive cylinder 26 driving the connecting rod 21 to swing around the rotating shaft 23 through the joint bearing 27 and the pin 29.

[0033] Please continue reading. Figure 3 and Figure 5 When the extension end of the drive cylinder 26 extends, it pushes the pin 29 through the spherical bearing 27, causing the connecting rod 21 to drive the turning rod 22 to swing towards the discharge port. When the drive cylinder 26 retracts, it drives the turning rod 22 to return to its original position, completing one turning action. The main function of the spherical bearing 27 is to support the rotating mechanical body, reduce the coefficient of friction during movement, and ensure the rotational accuracy and stability of the mechanical equipment. The design and manufacturing process of this bearing undergoes strict quality control to ensure its excellent performance and long service life during use. This bearing is existing technology and will not be described in detail here.

[0034] A sensor control system is installed on the support frame 12. The sensor control system is connected to the drive component and is used to control the movement of the drive component, thereby controlling the lever mechanism to work. The sensor control system includes a height detector 14 installed at the feed inlet of the glutinous rice ball machine 11. A dough detection switch 15 is provided at the bottom of the support frame 12. A position detection switch 16 is installed on the support frame 12. Relays are provided on the height detector 14, the dough detection switch 15, the position detection switch 16, and the drive component.

[0035] The dough block detection switch 15 detects the position of the dough block. When the dough block reaches the designated position, the relay on the dough block detection switch 15 controls the relay on the drive cylinder 26 to open. The drive cylinder 26 starts to work, pushing the spherical bearing 27 to drive the pin 29 to move, thereby driving the connecting rod 21 to swing around the rotating shaft 23. The dough pushing rod 22 then moves to push the dough block towards the discharge port. The dough block detection switch 15 is an Omron E3Z-D62 photoelectric sensor, but it can also be other photoelectric sensors with the same function.

[0036] Simultaneously, when the pin 29 moves to the position detection switch 16, the relay on the position detection switch 16 controls the drive cylinder 26 to stop running, completing one noodle-turning action. At the same time, the height detector 14 monitors the height of the noodle blocks in real time. If the noodle blocks are piled up too high, the relay on the height detector 14 controls the relay on the drive cylinder 26 to close, thereby stopping the action of the noodle-turning rod 22, preventing the feed inlet from being blocked, and ensuring the stable and safe operation of the equipment.

[0037] A baffle 30 is fixedly installed on the side of the support rod 18 facing the dough by screws. A baffle plate 31 with gradually increasing height from the end near the dough to the end away from the dough is installed at the bottom of the baffle 30. The inclined design of the baffle plate 31 can effectively guide the dough to slide along its surface and prevent the dough from getting too close to the support rod 18, thus affecting the dough-pulling effect.

[0038] Please see Figure 1-5 Working principle: When dough pieces are fed onto conveyor 10, dough piece detection switch 15 detects their arrival. The relay on dough piece detection switch 15 controls the drive cylinder 26 to start, pushing the spherical bearing 27 to move the pin 29, thereby driving the connecting rod 21 to swing around the rotating shaft 23, causing the dough-pushing rod 22 to move and push the dough pieces towards the discharge port. When the pin 29 moves to the detection switch 16, its relay controls the drive cylinder 26 to stop running, completing one dough-pushing action. At the same time, height detector 14 monitors the dough piece height in real time. If the dough pieces accumulate too high, the relay on height detector 14 will control the drive cylinder 26 to close, stopping the action of the dough-pushing rod 22 to prevent blockage of the feed port and ensure stable operation of the equipment.
