Description

Technical Field

[0001] The utility model belongs to the technical field of PVC film processing and relates to a PVC film raw material conveying device. Background Art

[0002] PVC film, primarily composed of polyvinyl chloride, is a slightly yellowish, translucent, and lustrous material. Its transparency is superior to that of polyethylene and polypropylene, but inferior to that of polystyrene. Common products made from PVC include sheet materials, pipes, shoe soles, toys, doors and windows, electrical wiring, and stationery. Before calendering, PVC film requires a conveyor system to transport the raw material to the calendering rollers. Therefore, to ensure uniform and efficient material delivery, a PVC film raw material conveyor system is essential. Summary of the Invention

[0005] The working principle of the utility model is as follows: the PVC film raw materials produced by the external feeding equipment are transported to the upper hopper through a hose, and then the raw materials are input into the guide box through the cyclic swing of the rotating device. The raw materials are evenly guided to the discharge port through the guide trough 1 and the guide trough 2, and fall into the calendering roller group below for processing and forming.

[0006] A material guide is installed below the discharge port.

[0007] The above structure is adopted to facilitate the export of raw materials.

[0008] The material guide box is fixed on the mounting seat through a bolt fixing structure.

[0009] The above structure is adopted to perform positioning and keep the upper hopper relatively fixed.

[0010] The surfaces of the material guide box including the first material guide trough and the second material guide trough are both smoothed.

[0011] The above structure is adopted to ensure the flow of raw materials.

[0012] The inner cross section of the material guide box is V-shaped.

[0013] The above structure is adopted to assist in guiding the raw materials.

[0014] Compared with the existing technology, the PVC film raw material conveying device has the following advantages: the utility model is equipped with a pendulum conveying structure, which cooperates with the material guide trough structure to stably and evenly convey the raw materials while reducing the waste of raw materials.

[0019] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0020] like Figure 1-3 As shown, the PVC film raw material conveying device includes a mounting base 1, on which a hopper 3 is rotatably mounted via a rotating device 2. The feed end of the hopper 3 is connected to an external feeding device via a hose 4. A material guide box 5 is provided below the discharge port of the hopper 3. An arc-shaped protrusion 6 is provided below the corresponding position of the material guide box 5 and the upper hopper 3. A material guide trough 1 7 is provided on the arc-shaped protrusion 6. A material guide trough 2 8 corresponding to the material guide trough 1 7 is provided behind the material guide trough 1, and the material guide trough 2 8 leads to a discharge port 9 at the bottom of the material guide box 5.

[0021] The rotating device 2 in the present invention adopts an existing product, and when it swings, the speed is faster at the center of the material guide box 5 and slower at both ends, thereby ensuring a uniform outflow of raw materials.

[0022] The external feeding equipment in the utility model is an existing device.

[0023] A material guide 10 is installed below the discharge port 9 .

[0024] The material guide member 10 of the present invention is installed at the material discharge port 9 with a detachable structure and can be replaced and disassembled according to actual needs.

[0025] The material guide box 5 is fixed on the mounting base 1 through a bolt fixing structure.

[0026] In the present invention, the positions of the guide box 5 and the upper hopper 3 need to be arranged corresponding to the central axis.

[0027] The surface of the material guide box 5 including the material guide trough 1 7 and the material guide trough 2 8 are smoothed.

[0028] The internal cross section of the material guide box 5 is V-shaped.

[0029] The working principle of the utility model is as follows: the PVC film raw materials produced by the external feeding equipment are transported to the upper hopper 3 through the hose 4, and then the raw materials are input into the guide box 5 through the cyclic swing of the rotating device 2. The raw materials are evenly guided to the discharge port 9 through the guide trough 1 7 and the guide trough 2 8, and fall into the calendering roller group below through the discharge port 9 for processing and forming.

[0030] In the utility model, each mechanism is connected and driven by using the existing technology, and synchronous control is achieved through a control panel.

[0031] The above components are all common standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.
