Description

Technical Field

[0001] This application relates to the field of plastic processing technology, specifically to an automatic feeding device for an extruder. Background Technology

[0002] In the EPP foaming production process, the raw material granules are first processed into preforms through hot melting. The specific process involves heating and plasticizing the EPP granules in a melting device, then drawing them into fibers, followed by pelletizing to prepare standard granules, and finally foaming them into finished products. In the material conveying stage, a lifting conveyor is used to lift the bagged EPP raw materials into the extruder.

[0003] Due to the structural design limitations of the lifting conveyor, its feed inlet is located at a certain height above the ground. Since the raw materials are packaged in standard woven bags, operators must perform the following high-load tasks: first, unpack the bags; then, lift the entire bag of raw material into the closed feed housing; and finally, pour the granular material into the feed inlet. This manual feeding method is not only labor-intensive but also presents efficiency bottlenecks and safety hazards. Summary of the Invention

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes an automatic feeding device for an extruder, the technical solution of which includes:

The conveying surface of the lifting conveyor is used to receive packaging bags and to limit the packaging bags on the conveying surface of the lifting conveyor through the baffles.

[0007] An adjustable adsorption platform is provided at the feed inlet of the extruder and the discharge end of the lifting conveyor. The adsorption platform can be tilted to coincide with the conveying surface of the lifting conveyor so that the lifting conveyor can transport the packaging bag to the adsorption platform.

[0021] Reference Figures 1 to 2 This application proposes an embodiment of the automatic extruder feeding device, which includes:

[0022] An adjustable adsorption platform 10 is provided at the feed inlet 21 of the extruder 20;

[0023] The lifting conveyor 30 has a conveying surface that gradually decreases in height from its discharge end to its inlet end. The conveying surface of the lifting conveyor 30 is provided with several baffles 31 that are spaced apart. The conveying surface of the lifting conveyor 30 is used to receive packaging bags and to limit the packaging bags on the conveying surface of the lifting conveyor 30 by the baffles 31.

[0024] An adjustable adsorption platform 10 is provided at the feed inlet 21 of the extruder 20 and the discharge end of the lifting conveyor 30. The adsorption platform 10 can be tilted to coincide with the conveying surface of the lifting conveyor 30 so that the lifting conveyor 30 can convey the packaging bag to the adsorption platform 10 and adsorb the packaging bag on it. The platform 10 is tilted so that the side closest to the feed inlet 21 of the extruder 20 faces downward.

[0025] After the packaging bag containing EPP raw material granules is placed on the conveyor belt of the lifting conveyor 30, the baffle 31 on the lifting conveyor 30 limits the packaging bag on the conveying surface of the lifting conveyor 30 to prevent the packaging bag from sliding down. At this time, an opening is processed at the upward end of the packaging bag, and the lifting conveyor 30 conveys the packaging bag with the opening upward.

[0026] like Figure 1As shown, after the adsorption platform 10 is tilted to coincide with the conveying surface of the lifting conveyor 30, when the lifting conveyor 30 lifts the packaging bag to its discharge end, the packaging bag will be conveyed onto the adsorption platform 10. The lifting conveyor 30 continues to operate until the packaging bag is completely conveyed onto the adsorption platform 10; Figure 2 As shown, after the adsorption platform 10 adsorbs the packaging bag containing EPP raw material particles, the adsorption platform 10 continues to adjust its tilt direction so that the side closest to the feed port 21 of the extruder 20 faces downward and the side with the opening of the packaging bag faces into the feed port 21 of the extruder 20. At this time, the EPP raw material particles in the packaging bag will fall down along the adsorption platform 10 into the feed port 21 of the extruder 20 under the action of gravity, realizing automatic feeding.

[0027] A cutting mechanism can be installed on the lifting conveyor 30 to cut an opening in the packaging bag, so that one side of the opening of the packaging bag faces the feed inlet 21 of the extruder 20. In this embodiment, the lifting conveyor 30 is located on the side of the adsorption platform 10 away from the extruder 20. After the worker places the packaging bag on the lifting conveyor 30, he unties the knot at one end of the packaging bag so that one side of the opening of the packaging bag faces the feed inlet 21 of the extruder 20, which facilitates the recycling of the packaging bag in the later stage.

[0028] Specifically, the adsorption platform 10 includes a platform body 11, on which an adsorption cavity 12 and an adsorption hole 13 communicating with the adsorption cavity 12 are provided, and the adsorption cavity 12 is communicating with a vacuum device.

[0029] In this embodiment, the adsorption platform 10 is mounted on the extruder 20 via an adjustment mechanism 40. The adjustment mechanism 40 includes a plurality of telescopic adjustment members 41, which are vertically arranged below the adsorption platform 10. The lower end of each telescopic adjustment member 41 is hinged to the extruder 20, and the upper end is hinged to the lower end of the adsorption platform 10.

[0030] The multiple telescopic adjustment members 41 can adjust the angle and direction of the adsorption platform 10 by telescoping; when pouring the EPP raw material particles inside the packaging bag, the adjustment mechanism 40 can drive the adsorption platform 10 to rotate to near vertical position so that the EPP raw material particles inside the packaging bag are completely poured into the feed inlet 21 of the extruder 20. In this embodiment, there are four telescopic adjustment members 41, which are located at the four corners at the lower end of the adsorption platform 10.

[0031] Based on the above, furthermore, after the EPP raw material particles inside the packaging bag are completely poured out, the adsorption platform 10 stops adsorbing the packaging bag, and the collection device removes the packaging bag from the adsorption platform 10 for recycling.

[0032] Specifically, the collection mechanism 50 includes a two-dimensional drive component 51 and a gripper 52. The two-dimensional drive component 51 is disposed on one side of the adsorption platform 10, and the gripper 52 is mounted on the two-dimensional drive component 51. The two-dimensional drive component 51 is used to drive the gripper 52 to move in two dimensions in a vertical plane.

[0033] After the adsorption platform 10 stops adsorbing the packaging bag, the adjustment structure drives the adsorption platform 10 to move to a horizontal position. The two-dimensional drive component 51 drives the gripper 52 to move to a position close to the top of the adsorption platform 10. After the gripper 52 adsorbs the packaging bag on the adsorption platform 10, the two-dimensional drive component 51 drives the gripper 52 to move outside the adsorption platform 10, and the gripper 52 releases its adsorption of the packaging bag, thereby adsorbing empty packaging bags. The gripper 52 can be a claw or an adsorbent. After the claw grips the packaging bag or the adsorbent adsorbs the packaging bag, the two-dimensional drive component 51 drives the gripper 52 to move outside the adsorption platform 10, thereby realizing the transfer and collection of packaging bags on the adsorption platform 10.

[0034] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
