Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features.

[0017] The terms “front”, “back”, “upper” and “lower” in this application refer to the attached Figure 1 Front, back, top and bottom shown.

[0018] In the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0019] An embodiment of the present application provides a one-way feeding device, which is arranged on one side of the extrusion main machine, and is used to receive the edge materials cut by the production line and re-plasticize the edge materials to assist in feeding the extrusion main machine. The extrusion main machine has an auxiliary feeding port connected to the one-way feeding device 100 to receive the delivery of the one-way feeding device 100.

[0020] like Figure 1 , 2 As shown, the one-way feeding device 100 includes an extrusion auxiliary machine 10, a traction component 20 and a flow channel component 30. The traction component 20 and the flow channel component 30 are both arranged on the extrusion auxiliary machine 10. The traction component 20 is used to pull the edge material into the extrusion auxiliary machine 10, and the flow channel component 30 is used to transport the material plasticized by the extrusion auxiliary machine 10 to the auxiliary feed port of the extrusion main machine in a one-way manner.

[0021] The extrusion auxiliary machine 10 includes a barrel 1, an extrusion screw 2 coaxially inserted in the barrel 1, and a driving component 3 drivingly connected to the extrusion screw 2. The extrusion screw 2 extends from front to rear and rotates around its own axis in the barrel 1 under the drive of the driving component 3.

[0022] The barrel 1 includes a feed port 101 and a discharge port 102. The feed port 101 is opened on the side wall of the barrel 1, and the discharge port 102 is opened at the rear end of the barrel 1. The material enters the barrel 1 from the feed port 101, and the extrusion screw 2 crushes and shears the material in the barrel 1, and the plasticized material is discharged from the discharge port 102.

[0023] like Figure 1 As shown, the traction component 20 is arranged at the feed port 101 to pull the edge material into the feed port 101; the flow channel component 30 is arranged at the discharge port 102 to transport the material output from the discharge port 102 to the auxiliary feed port of the extruder main unit in one direction.

[0024] like Figure 3 , 4As shown, the traction component 20 includes an active traction roller 41, a passive traction roller 42, a traction motor 43, a feed seat 44 and an adjusting hand wheel 45. The active traction roller 41 and the passive traction roller 42 are arranged parallel to each other, and the two traction rollers are rotatably mounted on the feed seat 44. The feed seat 44 is mounted on the barrel 1. The feed seat 44 includes an inlet 441 and an outlet 442 arranged opposite to each other up and down. The outlet 442 is connected to the feed port 101. The active traction roller 41 and the passive traction roller 42 are arranged side by side between the inlet 441 and the outlet 442. The active traction roller 41 is connected to the traction motor 43 in driving connection, and rotates around its own axis under the drive of the traction motor 43; the passive traction roller 42 is connected to the adjusting hand wheel 45, and the adjusting hand wheel 45 is used to drive the passive traction roller 42 to approach and move away from the active traction roller 41 to adjust the distance between the passive traction roller 42 and the active traction roller 41; when the traction component 20 is pulling, the adjusting hand wheel 45 drives the passive traction roller 42 to approach the active traction roller 41 to press the edge material against the active traction roller 41.

[0025] A driving gear 46 is coaxially sleeved on one end of the active traction roller 41, and a passive gear 47 is coaxially sleeved on one end of the passive traction roller 42. The active gear 46 is meshed with the passive gear 47, so that the passive traction roller 42 and the active traction roller 41 rotate in the opposite direction to pull the clamped edge material, so that the material is pulled from the inlet 441 to the outlet 442, thereby realizing online collection of edge material.

[0026] like Figure 1 , 5 As shown, the flow channel component 30 includes a first flow channel 51 connected to the discharge port 102, a second flow channel 52 connected to the auxiliary feed port, and a flow channel valve 53 arranged in the first flow channel 51 and the second flow channel 52. The flow channel valve 53 is configured to be able to unidirectionally conduct along the direction of the first flow channel 51 toward the second flow channel 52, so that the material output from the discharge port 102 is unidirectionally transported to the auxiliary feed port.

[0027] The flow channel valve 53 includes a valve chamber 531 connecting the first flow channel 51 and the second flow channel 52, and a valve core 532 movably arranged in the valve chamber 531. A bracket 54 is coaxially arranged in the valve chamber 531. The valve core 532 is blocked by the bracket 54 on the side of the bracket 54 away from the second flow channel 52. The outer wall surface of the bracket 54 and the inner wall surface of the valve chamber 531 form an annular flow channel 541 connecting the first flow channel 51 and the second flow channel 52. The valve core 532 is spherical and is pushed by the material to move in the valve chamber 531. The diameter of the first flow channel 51 and the diameter of the second flow channel 52 are both smaller than the diameter of the valve core 532, and the diameter of the valve core 532 is smaller than the inner diameter of the valve chamber 531.

[0028] When the discharge port 102 of the barrel 1 conveys material to the flow channel component 30, the valve core 532 moves to the second flow channel 52 under the push of the flowing material and is blocked by the bracket 54. The material flowing through the first flow channel 51 is conveyed to the second flow channel 52 from the gap between the valve core 532 and the valve cavity 531 and the annular flow channel 541, and then conveyed to the auxiliary inlet of the extruder main unit; when the pressure in the second flow channel 52 is greater than that in the first flow channel 51, the material in the second flow channel 52 flows back to the first flow channel 51, and the valve core 532 moves to the first flow channel 51 under the push of the material. Since the diameter of the first flow channel 51 is smaller than the diameter of the valve core 532, the valve core 532 blocks the opening between the first flow channel 51 and the valve cavity 531, so that the material flowing back from the second flow channel 52 cannot flow back into the first flow channel 51, thereby realizing the unidirectional conveying of the material from the extrusion auxiliary machine 10 to the extrusion main unit, avoiding the unstable operation of the equipment caused by the reflux of the material.

[0029] like Figure 1 As shown, a plurality of heating coils 6 are arranged on the barrel 1 , and the heating coils 6 heat the barrel 1 so that the material reaches the process temperature in the extrusion auxiliary machine 10 , thereby improving the plasticization effect of the edge material in the extrusion auxiliary machine 10 .

[0030] The material extruded by the extruder is cooled, shaped, trimmed and cut after being extruded by the extrusion die. The cut edge material is led to the traction component 20, and the passive traction roller 42 presses the edge material against the active traction roller 41. The heating ring 6 on the extrusion auxiliary machine 10 heats the temperature of the barrel 1 to the process temperature. The traction motor 43 drives the active traction roller 41 to rotate, and at the same time, the driving component 3 drives the extrusion screw 2 to rotate. The active traction roller 41 and the passive traction roller 42 rotate to introduce the edge material into the barrel 1. The extrusion screw 2 rotates to stir and shear the introduced edge material. The material plasticized by the extrusion screw 2 is transported from the discharge port 102 to the first flow channel 51. The material pushes the valve core 532 to resist the bracket 54, and flows into the second flow channel 52 through the annular flow channel 541, and finally enters the auxiliary feed port of the extruder.

[0031] The one-way feeding device of the present application is arranged on one side of the extruder main unit to convey the molten material plasticized from the collected side materials to the extruder main unit, collect the side materials online, save energy and reduce costs; the flow channel component 30 conveys the material output by the one-way feeding device 100 to the extruder main unit in a one-way direction, which can improve the stability of the equipment operation.

[0032] 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.
