Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, specifically a feeding device for the production of plastic hollow boards. Background Technology

[0002] Hollow core plastic sheets (also called hollow partition boards, corrugated boards, double-wall boards, or corrugated panels) are made of modern chemical HDPE and HDPP materials. They are a new type of material that is lightweight (hollow structure), non-toxic, non-polluting, waterproof, shockproof, anti-aging, corrosion-resistant, and available in a variety of colors. Compared to cardboard structures, hollow core sheets offer advantages such as moisture resistance, corrosion resistance, and lighter weight. Compared to injection-molded products, hollow core sheets offer advantages such as shock resistance, flexible structural design, and no need for injection molds.

[0003] In the production of plastic hollow boards, raw materials need to be fed into the machine for molding and shaping. However, the current feeding device has a relatively simple structure. When feeding a large amount of material at a time, the feed inlet of the feeding device is prone to blockage. Therefore, we propose a feeding device for the production of plastic hollow boards. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a feeding device for the production of plastic hollow boards, which can avoid the feed inlet being blocked during feeding and can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for the production of plastic hollow boards, comprising a feeding half-pipe and a feeding assembly;

[0006] Feeding half-pipes: There are two feeding half-pipes, which are connected by evenly distributed fastening bolts. Feeding components are installed inside the two feeding half-pipes.

[0007] Feeding assembly: includes a conical feed tube, a fixed plate, a slide bar, a lever plate, and an extrusion head. A feed inlet is located at the right end of the upper feeding half-tube surface. A conical feed tube is fixed inside the feed inlet. A fixed plate is fixed at the upper end of the conical feed tube. A sliding hole is located on the left side of the fixed plate. A slide bar is slidably connected inside the sliding hole. Evenly distributed lever plates are fixed at the lower end of the slide bar's circumference. An extrusion head is fixed at the upper end of the slide bar. A rotating assembly and an extrusion assembly are mounted on the upper side of the fixed plate. The extrusion assembly is in contact with the extrusion head. The upper end of the rotating assembly is connected to the extrusion head. By setting up the feeding assembly, the material required for producing plastic hollow sheets is injected between the two feeding half-tubes.

[0008] Furthermore, the rotating assembly includes a fixed tube, a spiral opening, a rotating shaft, a support ring, and a spring. The fixed tube is fixed to the upper side of the fixed plate, and the slide rod is slidably connected inside the fixed tube. A spiral opening is formed on the circumferential surface of the fixed tube, and a rotating shaft is disposed inside the spiral opening. The rotating shaft is rotatably connected to the circumferential surface of the slide rod. A support ring and a spring are sleeved on the circumferential surface of the slide rod. The upper end of the spring is fixed to the lower end of the support ring, and the lower end of the spring is fixed to the upper end of the fixed tube. The support ring is rotatably connected to the lower end of the extrusion head. By setting the rotating assembly, all the actuating plates are driven to rotate to stir the raw material inside the conical feed tube, thus avoiding blockage during feeding.

[0009] Furthermore, the extrusion assembly includes a fixed frame, a first motor, and an extrusion cam. The fixed frame is fixed to the upper side of the fixed plate, and the first motor is installed on the front side of the fixed frame. The extrusion cam is rotatably connected inside the fixed frame. The output shaft of the first motor is fixed to the front end of the extrusion cam. The extrusion cam is in contact with the extrusion head. The input end of the first motor is electrically connected to the output end of an external control switch group. By setting the extrusion assembly, the extrusion head is driven to reciprocate up and down.

[0010] Furthermore, the feeding assembly includes a fixing ring, a spiral feeding rod, and a second motor. Two corresponding fixing rings are arranged between the two feeding half-pipes. The two fixing rings are respectively fixed to the left and right ends inside the upper feeding half-pipe. The spiral feeding rod is rotatably connected inside the two fixing rings. The left end of the left fixing ring is equipped with the second motor. The output shaft of the second motor is fixed to the left end of the spiral feeding rod. The input end of the second motor is electrically connected to the output end of an external control switch group. Feeding is performed by setting up the feeding assembly.

[0011] Furthermore, a discharge port is provided at the left end of the surface of the lower feeding half-pipe, and a discharge pipe is fixed inside the discharge port for discharging materials.

[0012] Furthermore, a support frame is fixed to the right end of the surface of the lower feeding half-pipe, and a base plate is fixed to the lower side of the support frame. The base plate has evenly distributed mounting holes on its edge, and the lower feeding half-pipe is supported by the support frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This feeding device for the production of plastic hollow boards has the following advantages:

[0014] 1. The extrusion cam driven by the extrusion assembly drives the slide bar to move up and down reciprocally. At the same time, the cooperation between the spiral port and the rotating shaft in the rotating assembly makes the slide bar rotate synchronously when moving vertically. This drives the agitator plate to agitate the material in the conical feed tube in both directions, i.e., vibrate up and down and rotate and stir, effectively breaking up material accumulation and fundamentally avoiding the problem of feed port blockage.

[0015] 2. The two feeding half-pipes are connected by evenly distributed fastening bolts. Combined with the independent support design of the spiral feeding rod, it can be quickly disassembled, which is convenient for cleaning residual materials or maintaining internal components, significantly improving equipment maintenance efficiency and service life.
