[0021] Please refer to Figures 1-4 The embodiment provides a technical scheme: a feeding assembly for PE bag production, which comprises an upper hopper 1 and uniform feeding parts 3.
[0022] The upper hopper 1 is provided with an upper feeding pipe 2 at the lower end, and the upper feeding pipe 2 is in communication with the upper hopper 1. The left end of the upper feeding pipe 2 is a closed structure, providing space for the feeding of polyethylene raw materials. The upper feeding pipe 2 gradually inclines downward from left to right, facilitating the rightward movement of the polyethylene raw materials inside the upper feeding pipe 2. The surface of the upper hopper 1 is provided with a single-chip microcomputer 7, the input end of which is electrically connected to an external power supply to control the start and stop of the whole device.

The input end of the motor 4 is electrically connected to the output end of the single-chip microcomputer 7. The left and right inner walls of the upper hopper 1 are both provided with a guide plate 5 to guide the movement track of the polyethylene raw materials inside the upper hopper 1 and reduce the accumulation of raw materials.
[0023] The uniform feeding component 3 comprises a rotating column 31, a partition plate 32 and a vibrating plate 33. The rotating column 31 is rotationally connected to the left end of the feeding pipe 2. The outer arc surface of the rotating column 31 is respectively provided with the partition plate 32. The annularly distributed partition plates 32 are all attached to the inner arc surface of the feeding pipe 2. The vibrating plates 33 are respectively transversely and slidingly connected to the inner lower end of the feeding hopper 1. The arc surface of the lower end of the vibrating plate 33 has a diameter equal to that of the inner arc surface of the feeding pipe 2. The rotating column 31 drives the partition plate 32 to rotate, while the feeding pipe 2 gradually inclines downward from left to right. Through cooperation with the gravity of the polyethylene raw material, the polyethylene raw material is gradually moved to the right in the circumferential movement process in the feeding pipe 2, reducing the influence of raw material accumulation on the feeding speed. At the same time, the vibrating plate 33 reciprocally moves left and right to vibrate the raw material, so that the raw material more smoothly enters the adjacent two partition plates 32. At the same time, the arc surface at the lower end of the vibrating plate 33 pushes and scrapes the raw material, so that the inside of the adjacent two partition plates 32 is completely filled with the polyethylene raw material, ensuring the uniform feeding of the polyethylene raw material. The uniform feeding component 3 further comprises a guide column 34, a mounting plate 36 and a vibrating motor 37. The guide column 34 is arranged between the vibrating plates 33. The left and right ends of the guide column 34 pass through the guide holes on the surface of the feeding hopper 1 and are provided with the mounting plates 36. The surface of the mounting plate 36 is provided with the vibrating motor 37. The input end of the vibrating motor 37 is electrically connected to the output end of the single-chip microcomputer 7.

The uniform feeding component 3 further comprises a spring 35. The spring 35 is movably sleeved on the outer arc surface of the left and right ends of the guide column 34. One end of the spring 35 close to the horizontal center of the guide column 34 is fixedly connected to the adjacent vibrating plate 33. The other end of the spring 35 is fixedly connected to the inner wall of the feeding hopper 1, so that the reciprocating movement of the guide column 34 is more stable. The uniform feeding component 3 further comprises an elastic rubber pad 38. The elastic rubber pad 38 is arranged between the upper end of the vibrating plate 33 and the inner wall of the feeding hopper 1. The elastic rubber pad 38 is located at the upper end of the leftmost vibrating plate 33 and the upper end of the rightmost vibrating plate 33, blocking the raw material from entering between the vibrating plate 33 on the outside and the inner wall of the feeding hopper 1. The side of the mounting plate 36 close to the feeding hopper 1 is provided with the buffer rubber pad 6, reducing the impact of the reciprocating movement of the mounting plate 36 on the feeding hopper 1.
[0024] The working principle of the feeding assembly for PE bag production is as follows: in the process of PE bag production, the polyethylene raw material is poured into the inside of the feeding hopper 1, the polyethylene raw material enters the inside of the feeding pipe 2 through the feeding hopper 1, and finally is discharged from the opening at the right end of the feeding pipe 2, thereby providing raw materials for the work of the PE bag production equipment; in the feeding process, the single-chip microcomputer 7 starts the motor 4, the output shaft of the motor 4 drives the rotating column 31 and the partition plate 32 to rotate, at the same time, the feeding pipe 2 gradually inclines downward from left to right, and through cooperation with the gravity of the polyethylene raw material, the polyethylene raw material gradually moves to the right in the circumferential movement process in the feeding pipe 2, thereby reducing the influence of raw material accumulation on the feeding speed; at the same time, the vibration motor 37 is started, the elastic force of the spring 35 is overcome, the guide column 34 moves back and forth in the guide hole on the surface of the feeding hopper 1, the vibration plate 33 moves back and forth, the raw material is vibrated, the raw material more smoothly enters the adjacent two partition plates 32, at the same time, the arc surface at the lower end of the vibration plate 33 pushes and scrapes the raw material, the inside of the adjacent two partition plates 32 is completely filled with the polyethylene raw material, and uniform feeding of the polyethylene raw material is ensured.
