Description

Technical Field

[0001] This utility model relates to the field of sheet forming technology, and in particular to an extruder feeding device. Background Technology

[0002] Material extruders are key equipment for realizing a circular economy in the plastics industry, transforming low-value, complex plastic scraps into high-value, high-quality sheet products. Current extruder feed hopper structures are prone to a "bridge" effect during feeding, meaning the material easily forms a stable bridging structure above the feed hopper, preventing it from smoothly entering the feed barrel. Traditionally, to improve this feeding defect, propeller-equipped blades are used to disperse the material or to actively feed it into the barrel. However, the dispersion method may create bridge structures elsewhere, failing to completely eliminate material blockage. As for the active feeding method, the propeller blades experience significant resistance, and continued rotation after sufficient material feeding encounters considerable resistance, leading to severe energy consumption and potential damage to moving parts, hindering efficient production. Summary of the Invention

[0003] The purpose of this invention is to provide an extruder feeding device for adjusting the material inlet during the material feeding process. By changing the width of the inlet and fluctuating the material in the inlet, the material is dispersed and falls, which helps to achieve efficient feeding. The passive feeding method can reduce energy consumption, thereby achieving low power consumption and high efficiency operation.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] An extruder feeding device includes a feed barrel with a feed hopper on it. Both sides of the feed hopper have openings. A positioning frame is provided at each opening, and a fabric covering is fixedly mounted on the positioning frame. The two fabric coverings and the inner cavity of the feed hopper together form a feeding chamber. A horizontal movable rod is abutted against the outer side of the fabric covering, and the movable rod is connected to a drive mechanism that drives it to reciprocate.

[0006] Furthermore, the driving mechanism includes two turntables rotatably disposed on both sides of the opening and a turntable driving assembly for driving the two turntables to rotate synchronously; the two ends of the movable rod are respectively connected to the two turntables through connecting rods.

[0007] Furthermore, one end of the connecting rod is fixedly positioned at the center of the turntable.

[0008] Furthermore, a connecting shaft is fixedly installed at a non-axial position of the turntable, and one end of the connecting rod is hinged to the connecting shaft; a sliding groove is provided in the middle of the connecting rod, and a positioning shaft is slidably fitted in the sliding groove, and the positioning shaft is connected to the positioning frame.

[0009] Furthermore, the turntable drive assembly includes two first gears, two second gears, a concentric rod, and a rotary drive assembly; the concentric rod is rotatably mounted on the feed hopper, the two first gears are coaxially connected through the concentric rod, one second gear is coaxially connected to one turntable, and the second gear meshes with the first gear located at the same end; the rotary drive assembly drives the concentric rod to rotate.

[0010] Furthermore, the rotary drive assembly includes two hollow rotary cylinders, and the concentric rod is located inside the hollow of the two rotary cylinders and connected to the movable end of the rotary cylinder.

[0011] Furthermore, mounting brackets are provided at both ends of the positioning frame, and the two turntables are rotatably arranged on opposite sides of the two mounting brackets; the turntable drive assembly is mounted on the two mounting brackets.

[0012] Furthermore, the two movable rods are symmetrically arranged with respect to the center plane of the feed hopper.

[0013] The beneficial effects of this utility model are as follows: By setting an opening on the side wall of the feed hopper, the drive mechanism drives the movable rod to swing back and forth, thereby driving the corresponding cloth wrapping to move. This allows adjustment of the width and inclination of the discharge port below the feed chamber of the feed hopper, which helps to break the air bridge environment and allows the material to smoothly enter the interior of the feeder cylinder. Compared with the traditional active feeding method of rotary blade crusher, this method can effectively reduce the energy consumption of the operation. The passive feeding method can continuously operate and stably supply material with low energy consumption, which is conducive to low power consumption and stable production.

Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1 to 5 As shown, an extruder feeding device includes a feeder cylinder 1, on which a feed hopper 2 is provided. Both sides of the feed hopper 2 are provided with openings. A positioning frame 3 is provided at the opening, and a cloth 4 is fixedly provided on the positioning frame 3. The two cloths 4 and the inner cavity of the feed hopper 2 together form a feeding chamber. A horizontal movable rod 5 is provided on the outer side of the cloth 4, and the movable rod 5 is connected to a drive mechanism 6 that drives it to swing back and forth.

[0022] This invention discloses an extruder feeding device for adjusting the material inlet during material feeding. A drive mechanism 6 drives a corresponding movable rod 5 to reciprocate, altering the spatial position of the feeding inlet formed by the fabric 4 and the feed hopper 2, thus preventing material accumulation due to air bridging. Furthermore, the movable rod 5 can effectively target vulnerable areas where air bridging occurs, facilitating disruption of the air bridging structure and ensuring smooth material entry into the feeder barrel 1. Compared to traditional active feeding methods that utilize a rotary blade structure for active feeding or material dispersion and monitor the feeding inlet for material discharge, this invention primarily employs a passive feeding method. This effectively reduces energy consumption and failure rate during equipment operation, contributing to efficient and stable operation.

[0023] Specifically, in this embodiment, the driving mechanism 6 includes two turntables 61 rotatably disposed on both sides of the opening and a turntable driving assembly for driving the two turntables 61 to rotate synchronously; wherein, the two ends of the positioning frame 3 are provided with mounting brackets 7, and the two turntables 61 are coaxially rotatably connected to the opposite sides of the two mounting brackets 7; the turntable driving assembly is mounted on the two mounting brackets 7; the two ends of the movable rod 5 are respectively connected to the two turntables 61 through connecting rods 65.

[0024] In a preferred embodiment of this invention, one end of the connecting rod 62 is fixedly disposed at the center of the turntable 61. In use, the turntable drive assembly drives the two turntables 61 to rotate synchronously, thereby causing the two connecting rods 62 to rotate synchronously, which in turn causes the movable rod 5 to reciprocate up and down around the central axis of the two turntables 61.

[0025] In another preferred embodiment of this invention, a connecting shaft 63 is fixedly installed at a non-axial position of the turntable 61, and one end of the connecting rod 62 is hinged to the connecting shaft 63. A groove is provided in the middle of the connecting rod 62, and a positioning shaft 64 is slidably fitted in the groove. The positioning shaft 64 is connected to the positioning frame 3. In use, the turntable drive assembly drives the two turntables 61 to rotate synchronously, causing the two connecting rods 62 to rotate eccentrically. Through the sliding fit between the positioning shaft 64 and the groove on the connecting rod 62, the movable rod 5 swings up and down reciprocally.

[0026] Furthermore, the turntable drive assembly includes two first gears 65, two second gears 66, a concentric rod 67, and a rotary drive assembly; wherein, the concentric rod 67 is rotatably mounted on two mounting brackets 7, the two first gears 65 are coaxially connected through the concentric rod 67, and one second gear 66 is coaxially connected to a turntable 61, and the second gear 66 meshes with the first gear 65 located at the same end; the rotary drive assembly drives the concentric rod 67 to rotate. Preferably, in this embodiment, the rotary drive assembly includes two hollow rotary cylinders 68, the concentric rod 67 is located inside the hollow of the two rotary cylinders 68, and is connected to the movable end of the rotary cylinders 68.

[0027] In use, driven by two rotary cylinders 68, the concentric rod 67 rotates, which drives the two first gears 65 to rotate synchronously. Through the meshing transmission between the second gear 66 and the first gear 65 located at the same end, the two turntables 61 can be rotated synchronously.

[0028] In this embodiment, preferably, the two movable rods 5 are symmetrically arranged with respect to the center plane of the feed hopper 2.
