DETAILED DESCRIPTION

[0019] To describe the technical content, structural features, achieved purpose and effect of the application in detail, the technical solutions in the embodiments of the application will be described below in conjunction with the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all of the embodiments. In the following description, for the purpose of explanation, many 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 the case of one or more equivalent arrangements. In addition, various exemplary embodiments may be different, but not necessarily exclusive. For example, without departing from the inventive concept, the specific shape, structure and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0020] The terms “front”, “rear”, “left” and “right” in this application refer to the attached Figure 1 Front, back, left and right shown.

[0021] An embodiment of the present application provides a material discharge device for an extruder, which is installed at a feed port of a barrel of the extruder so as to be able to provide material into the feed port.

[0022] like Figure 1 As shown, the material unloading device 100 includes: a material unloading seat 10 , a gate assembly 20 disposed on the material unloading seat 10 , and a feeder 30 connected to the material unloading seat 10 .

[0023] like Figure 2 , 3 As shown, the material discharge seat 10 includes an inlet 11 and an outlet 12 which are opposite to each other in the upper and lower parts. A feed hopper is installed on the inlet 11 to receive the material input by the feed hopper. The outlet 12 is connected to the feed port of the extruder and is fluidically connected to each other. The area of ​​the inlet 11 is larger than that of the outlet 12 to avoid bridging of the material at the feed port.

[0024] The gate assembly 20 is installed at the inlet 11 to control the opening and closing of the inlet 11. The gate assembly 20 is located between the feed hopper and the unloading seat 10 and is used to control the feeding and stopping of the feed hopper. The gate assembly 20 includes a gate 2 and a linkage mechanism 3. The gate 2 is configured to completely cover the inlet 11.

[0025] like Figure 1 , 3As shown, the linkage mechanism 3 is connected between the gate plate 2 and the material discharging seat 10, and is used to drive the gate plate 2 to move in the first direction. In the embodiment of the present application, the first direction is the left-right direction. The linkage mechanism 3 drives the gate plate 2 to move in the left-right direction to adjust the area of ​​the gate plate 2 covering the inlet 11. When the gate plate 2 completely covers the inlet 11, the fluid connection between the feed hopper and the inlet 11 is disconnected, and it is impossible to feed into the feed seat 10; when the gate plate 2 moves in the left-right direction to reduce the area covering the inlet 11, the feed hopper is connected to the inlet 11, and the material in the feed hopper is transported from the uncovered inlet 11 to the material discharging seat 10; the linkage mechanism 3 also changes the area covering the inlet 11 by moving the gate plate 2, thereby adjusting the flow rate of the material input from the feed hopper to the material discharging seat 10.

[0026] In the embodiment of the present application, the linkage mechanism 3 is arranged on the right side of the discharge seat 10, and the discharge seat is designed to be elevated so that the linkage mechanism 3 can be located above the cooling water pipe of the extruder, thereby avoiding interference between the linkage mechanism 3 and the cooling water pipe of the extruder during operation.

[0027] The linkage mechanism 3 includes a fixed frame 31, a connecting screw 32, a screw nut 33 and a driving handwheel 34. The fixed frame 31 is fixedly installed on the right side of the unloading seat 10, and the screw nut 33 is fixedly installed on the right end of the fixed frame 31. The connecting screw 32 is passed through the fixed frame 31 along the left-right direction and is threadedly connected with the screw nut 33. One end of the connecting screw 32 is connected to the gate 2, and the other end is connected to the driving handwheel 34. The driving handwheel is operated by the operator to drive the connecting screw 32 to rotate around its own axis; the gate 2 is configured to be able to move along the left-right direction when the connecting screw 32 rotates around its own axis.

[0028] like Figure 1 As shown, the feeder 30 is connected to the material discharge seat 10, and is arranged in sequence with the material discharge seat 10 along a second direction perpendicular to the first direction. In the embodiment of the present application, the second direction is the front-to-back direction, and the feeder 30 is installed at the front end of the material discharge seat 10. The feeder 30 conveys the auxiliary material from the front side of the material discharge seat 10, and the feed hopper conveys the material from the top of the material discharge seat 10. The material and the auxiliary material are mixed in the material discharge seat 10 and conveyed to the barrel of the extruder from the feed port.

[0029] The driving hand wheels 34 of the feeder 30 and the gate assembly 20 are arranged at two positions at 90 degrees, so that the operator can operate the feeder 30 and the gate assembly 20 on the same side of the extruder. The operator can feed and stop the feeder 30 and feed and stop the feed hopper on the same side of the extruder. There is no need to install stairs on both sides of the extruder, and the operator can effectively avoid walking back and forth on both sides of the extruder to operate, which effectively reduces the difficulty of operation and saves labor and production costs.

[0030] like Figure 1, 2 As shown, the feeder 30 includes a feeding hopper 4, a feeding barrel 5 and a feeding screw (not shown in the figure), the feeding barrel 5 is connected to the discharge seat 10, the feeding screw is rotatably arranged in the feeding barrel 5, the feeding hopper 4 is installed above the feeding barrel 5 and is connected to the feeding barrel 5, and the feeding screw rotates in the feeding barrel 5 to input the auxiliary material in the feeding hopper 4 from the front to the back from the front side of the discharge seat 10.

[0031] The feeding hopper 4 includes a pair of side plates 41 arranged opposite to each other in the front-rear direction. The pair of side plates 41 are both inclined toward the front side to provide an installation position for the feeding hopper installed at the inlet.

[0032] like Figure 2 , 3 As shown, the material discharge seat 10 includes a pair of side walls 13 arranged opposite to each other in the front-to-back direction, one of the side walls 13 is provided with an input hole (not shown in the figure) connected to the feeder barrel 5, and the other side wall 13 is provided with an observation window 14. The observation window 14 allows the operator to observe the feeding situation in the material discharge seat 10 from the outside of the material discharge seat 10. The operator can control the feeding of the feeder 30 and the feed hopper according to the observed results.

[0033] The present application enables the feeder and the gate assembly to complete the operation on the same side of the extruder, thereby saving operation stairs, reducing operation difficulty, and saving labor and production costs.

[0034] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, and the scope of protection required by the present application is defined by the attached claims, description and their equivalents.
