[0021] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0022] according to Figure 1 、 2 As shown in Figures 3 and 4, this embodiment provides an automatic feeding mechanism for processing straws, comprising a first feeding seat 1 and a second feeding seat 6 provided on one side of the first feeding seat 1. A conveyor belt structure for sequentially feeding the straws is provided on the inner side of the first feeding seat 1, and a second feeding belt 7 is provided on the inner side of the second feeding seat 6.

[0023] A limiting roller 13 is provided on the inner side of the second feeding seat 6. The limiting roller 13 is placed above the second feeding belt 7. A lifting device is provided on the upper end of the second feeding seat 6 for pushing the limiting roller 13 down.

[0024] Straws are stacked horizontally within the second feeder 6. Second feeder belt 7 pushes the straws onto the guide conveyor structure. A lifting mechanism lowers limit roller 13, leaving just enough space between limit roller 13 and second feeder belt 7 to allow a single straw to enter and exit, ensuring orderly delivery of the straws. The height of limit roller 13 is adjustable to accommodate straws of varying diameters and prevent clogging during delivery, providing excellent flexibility.

[0025] Two inclined baffles 15 for guiding the straws are provided on the inner side of the second feeding seat 6, and a gap is left between the two inclined baffles 15. The inclined baffles 15 are rotatably connected to the second feeding seat 6. A loading device for pushing the straws between the two inclined baffles 15 is provided on the outer side of the second feeding seat 6. An adjustment device for controlling the angle of the inclined baffle 15 is provided on the outer side of the second feeding seat 6.

[0026] The loading device pushes the straw between the two inclined baffles 15 in the second feeding seat 6. The inclined baffle 15 will guide the straw that falls on the plate surface. The straw slides from the inclined baffle 15 to the second feeding belt 7, and then is sent out from the gap between the inclined baffle 15 and the second feeding belt 7. The inclined baffle 15 can rotate slightly during guidance, further ensuring that the straw will not be blocked when being sent out.

[0027] Specifically, the conveyor belt structure includes a first feeding belt 3, which is obliquely arranged on the inner side of the first feeding seat 1, and the input end of the limiting roller 13 is placed below the output end of the second feeding belt 7. A plurality of partition plates 4 are provided on the outer side of the limiting roller 13, and a gap is left between two adjacent partition plates 4 to allow a single straw to be placed in. Two limiting plates 2 are fixedly provided on the upper end of the first feeding seat 1, and the partition plate 4 is placed between the two groups of limiting plates 2.

[0028] The output end of the second feeding belt 7 is arranged above the first feeding seat 1, and the loading device is arranged above the input end of the second feeding belt 7. The straws sent out from the second feeding belt 7 will fall on the first feeding belt 3 and are sent out in sequence between the two adjacent partition plates 4 on the first feeding belt 3.

[0029] More specifically, the loading device includes a third feed base 9 and a feeding notch 8 formed on the side of the second feed base 6. The third feed base 9 is fixedly connected to the outside of the second feed base 6. A third feed belt 10 is installed within the third feed base 9, and the input end of the third feed belt 10 extends into the feeding notch 8. Straws fall onto the third feed belt 10 through the hopper, and the third feed belt 10 pushes the straws between two inclined baffles 15.

[0030] Regarding the lifting device: The lifting device includes a movable bracket 12 and two sets of electric push rods 14. The limit roller 13 is rotatably connected to the inner side of the movable bracket 12. The movable bracket 12 is slidably connected to the chute provided at the upper end of the second feed base 6. The electric push rods 14 are fixedly connected to the left and right sides of the second feed base 6. The output ends of the electric push rods 14 are fixedly connected to the movable bracket 12. The height of the limit roller 13 is controlled by the two sets of electric push rods 14. When a blockage occurs between the limit roller 13 and the second feed belt 7, the electric push rods 14 can be used to move the limit roller 13 up and down. The limit roller 13 pushes the blocked straw away by moving up and down.

[0031] Regarding the adjustment device, the adjustment device includes two sets of worm gears 16, which are rotatably connected to the outside of the second feed seat 6. The connection between the inclined baffle 15 and the second feed seat 6 is provided with a movable pin that supports the rotation of the inclined baffle 15. The movable pin is fixedly connected to the worm gear 16. The outside of the second feed seat 6 is fixedly connected to a rod bracket 17. A worm shaft 19 is rotatably provided inside the rod bracket 17. The worm shaft 19 engages with the worm gear 16. A motor 18 is provided on the outside of the rod bracket 17 for controlling the rotation of the worm shaft 19. The motor 18 drives the worm shaft 19 to rotate. During the rotation of the worm shaft 19, it cooperates with the two sets of worm gears 16 to drive the two sets of second feed seats 6 to rotate. During the rotation of the worm gear 16, the inclined baffle 15 is rotated with it, expanding or reducing the gap between the inclined baffle 15 and the second feed belt 7, ensuring that the straws will not be blocked when they are fed out.

[0032] More specifically, the worm shaft 19 includes two sets of worms fixed to each other, with the threads on the outer sides of the two sets of worms rotating in opposite directions. The two sets of worm wheels 16 are respectively engaged with the two sets of worm shafts 19. The advantage of this design is that when the motor 18 drives the worm shaft 19 to rotate, the two sets of worm wheels 16 engaged with the worm shaft 19 will rotate in opposite directions, and the two sets of inclined baffles 15 will not fall down while tilting up.

[0033] In the preferred embodiment, a first bracket 5 is provided at the bottom of the first feeding seat 1, and the first bracket 5 is fixedly connected to the first feeding seat 1. A second bracket 11 is provided at the bottom of the second feeding seat 6, and the second bracket 11 is fixedly connected to the second feeding seat 6. Reinforcing ribs are provided at the connection between the first bracket 5 and the first feeding seat 1, and the connection between the second bracket 11 and the second feeding seat 6. The first bracket 5 and the second bracket 11 are used to support the first feeding seat 1 and the second feeding seat 6 from the bottom, so that the first feeding seat 1 and the second feeding seat 6 are separated from the table or the ground. The provision of the reinforcing ribs can ensure that the support structure is stable.

[0034] How this application works:

[0035] The straws are stacked horizontally within the second feeder 6. The second feeder belt 7 pushes the straws onto the guide conveyor structure. A lifting device lowers the limit roller 13, leaving just enough space between the limit roller 13 and the second feeder belt 7 to allow a single straw to enter and exit, ensuring the orderly delivery of the straws. The limit roller 13 is height-adjustable to accommodate straws of varying diameters and prevent clogging during delivery. The loading device pushes the straws between two inclined baffles 15 within the second feeder 6. These baffles guide any straws that fall onto the baffles. The straws slide from these baffles onto the second feeder belt 7 and are then delivered outward through the gap between them. The baffles 15 rotate slightly during guidance, further ensuring that the straws do not become clogged during delivery.
