Technical Field

[0002] Optical film raw materials are generally transported at low pressure. The key issue is to choose the air supply pressure, pipeline diameter, material direction, etc. The current raw material transportation method adopts high-pressure or low-pressure intermittent transportation. This transportation method has a high material-to-gas ratio, low equipment cost, and the material in the tank can be completely discharged.

[0003] The patent document with the announcement number CN216403195U discloses an anti-static adhesion optical film feeding device, including a storage device and a material taking device; the storage device includes a base, and a lead screw is vertically penetrated on the base; the lead screw is matched with the base thread, so that the lead screw can move up and down when rotating, and the top of the lead screw is movably sleeved with a loading platform; it also includes four guide columns vertically arranged on the base, and the four guide columns are arranged around the loading platform, and the upper end of the guide column is provided with an anti-static brush facing the inside; it also includes a driving device for driving the lead screw to rotate; the optical film feeding device with the above structure automatically rubs the optical films that are adhered together through the anti-static brush to avoid its influence on subsequent production, saves the time of manual separation of optical films, and improves production efficiency.

In particular, the large number of valves causes serious wear and tear on the materials. Therefore, we propose a polyester film feeding device to solve the above problems. Utility Model Content

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Embodiment 1

[0027] Reference Figure 1-Figure 3 , a polyester film feeding device, comprising:

[0028] Automatic controller 1;

[0029] A dense valve seat 2 is arranged on one side of the automatic controller 1;

[0030] The high-precision rotary valve 3 is arranged on the top of the dense valve seat 2, and the high-precision rotary valve 3 is tightly connected with the dense valve seat 2;

[0031] The feeding hopper 4 is fixedly connected to the top of the high-precision rotary valve 3, and the feeding hopper 4 is made of a 2-5 mm stainless steel plate;

[0032] The automatic valve 10 is fixedly connected to the outlet of the dense valve seat 2;

[0033] The delivery pipeline 5 is fixedly connected to one side of the automatic valve 10, and the delivery pipeline 5 is made of 1-3 mm stainless steel sheet metal;

[0034] A receiving hopper 9 is arranged on one side of the conveying pipeline 5;

[0035] The metal separator 6 is arranged on one side of the conveying pipeline 5 .

[0036] Specifically, a metal separator 6 and a bag filter 8 are installed at the upper end of the receiving hopper 9 , and a cyclone separator 7 is connected to the bag filter 8 .

[0037] Specifically, the conveying pipeline 5 is connected to the metal separator 6 . The metal separator 6 is cylindrical, and a magnet is installed on the cylinder wall of the metal separator 6 .

[0038] Specifically, one end of the metal separator 6 is fixedly connected to the conveying pipeline 5 , and the other end of the metal separator 6 is fixedly connected to the cyclone separator 7 .

[0039] The implementation principle of a polyester film feeding device in the embodiment of the present application is as follows: the automatic controller 1 is started, and the material in the feeding hopper 4 enters the conveying pipeline 5 through the high-precision rotary valve 3. The high-precision rotary valve 3 has a structure and is equipped with a material suction port with a reasonable structure. The interior is assembled by an impeller. The impeller is driven by a variable speed motor or an inorganic transmission. It can be driven by a special motor to feed at a fixed speed;

[0040] The main function of the high-precision rotary valve 3 is to achieve quantitative discharging. In addition, the high-precision rotary valve 3 also has a certain function of blocking airflow, preventing airflow from flowing into the feeding hopper 4, and ensuring normal discharging. The ability to block airflow depends on the structure and processing accuracy of the high-precision rotary valve 3. A special dense valve seat 2 is also installed at the discharging end of the high-precision rotary valve 3, which can also be called a discharging nozzle. Its function is to turn the discharging port of the rotary valve into a negative pressure when there is a high-speed airflow in the conveying pipeline. Otherwise, the airflow passes through the impeller and prevents the material from flowing out, causing material blockage and inability to feed. The dense valve seat 2 has good air tightness.

[0041] The screened raw materials are blown into the metal separator 6 on the top of the silo, which prevents metal impurities from being in the raw materials. If any metal impurities are sucked into the cylinder wall, the transported materials are separated by the cyclone separator 7 and settled in the receiving hopper 9. The dust-containing air is filtered again by the bag filter 8 and discharged into the atmosphere. The material without impurities enters the receiving hopper 9.

[0042] The compressed air used at the same time has been strictly processed and has no pollution to the materials. During the conveying process, the accessories can be cooled, heated, dried, humidified, etc. The air pressure is 0.1-0.5MPa and the conveying speed is 3-10m / s.

[0043] The automatic valve 10 installed in the conveying pipeline 5 is opened during normal operation and automatically closed when encountering material blockage.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
