[0022] To illustrate the technical content, structural features, achieved objectives, and effects of the application in detail, the technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, structure, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0023] This application provides a pneumatic extruder hopper, which is installed on the barrel of an extruder and used to supply raw materials to the extruder. Figure 1 As shown, the pneumatic main unit hopper includes: a feed hopper 1, a feed seat 2 installed below the feed hopper 1, and a plate insertion mechanism 3 installed at the feed seat 2.

[0024] like Figure 1 , 2 As shown, the feed hopper 1 is funnel-shaped and has an inlet 11 and an outlet 12 arranged vertically opposite each other. The inlet 11 is used to feed material into the pneumatic main unit hopper, and the outlet 12 is used to convey material through the feed seat 2 to the barrel of the extruder. A discharge port is provided on the side wall of the feed hopper 1, which is located near the lower end of the feed hopper 1. When the extruder stops or the material is changed, the discharge port is used to discharge the material remaining in the feed hopper 1. A plug 13 is detachably installed on the discharge port. The plug 13 is removed when discharging material and is sealed in the discharge port at other times.

[0025] like Figure 2 , 3 As shown, a pair of first viewing windows 14 are also provided on the side wall of the feed hopper 1 for the operator to observe the inside of the feed hopper 1. The pair of first viewing windows 14 are staggered at the feed inlet and are at a 90-degree angle to each other.

[0026] like Figure 1-3 As shown, the feed seat 2 includes an upper and lower opposing feed inlet 21 and a lower outlet 22. The feed inlet 21 is opposite to and fluidly connected to the output outlet 12, and the feed inlet 21 is larger than the output outlet 22. A second viewing window 23 is provided on the side wall of the feed seat 2 for the operator to observe the inside of the feed seat 2. The operator can observe the material feeding situation between the feed seat 2 and the barrel through the second viewing window 23, and can promptly detect and solve problems, thereby improving production efficiency.

[0027] like Figure 1 , 2As shown in Figure 4, the insert plate mechanism 3 is installed at the feed inlet 21 of the feed seat 2. The insert plate mechanism 3 includes a cylinder support frame 31 installed on one side of the feed seat 2, a push cylinder 32 installed on the cylinder support frame 31, and an insert plate 33 that can block the flow between the output port 12 and the feed inlet 21. The push cylinder 32 is connected to the insert plate 33 to drive the insert plate 33 to move back and forth between a first position and a second position. In the first position, the insert plate 33 blocks the fluid communication between the output port 12 and the feed inlet 21, preventing the material in the feed hopper 1 from entering the feed seat 2. In the second position, the insert plate 33 is located outside the output port 12 and the feed inlet 21, allowing smooth conveying between the feed hopper 1 and the feed seat 2. The insert plate 33 is a sheet metal bending plate, which is easy to manufacture and is smooth and not easily deformed.

[0028] The top of the feed seat 2 is provided with an insertion slot 24 for inserting and removing the insert plate 33. The insert plate 33 cooperates with the insertion slot 24. The insertion slot 24 provides space for the movement of the insert plate 33 and guides the movement of the insert plate 33.

[0029] The cylinder support frame 31 includes a pair of connecting rods 311 and a cylinder support plate 312. One end of each connecting rod 311 is connected to the feed seat 2, and the other end is perpendicularly connected to the cylinder support plate 312. The extension direction of each connecting rod 311 is consistent with the movement direction of the insert plate 33. The cylinder body of the push cylinder 32 is mounted on the cylinder support plate 312, and the cylinder rod is connected to the insert plate 33.

[0030] The pneumatic main unit hopper of this application has a simple structure and a high degree of automation, saving time and labor. It can promptly cut off the fluid connection between the feed hopper and the feed seat, avoiding untimely manual operation and ensuring efficient production of the production line.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application.
