[0024] Reference Figure 1 and Figure 2 The embodiment of the present application provides an automatic feeding device for plastic particles, comprising: a mixer 100, provided with a discharge port; an extruder 200, provided with a feed hopper 210; a feeding mechanism, comprising a fixed frame 310, a feeding pipe 320, a feeding hopper 330, a screw 340 and a motor 350, wherein the feeding pipe 320 is tiltedly arranged on the fixed frame 310, the feeding hopper 330 is located below the discharge port, the feeding hopper 330 is connected to a first end of the feeding pipe 320, a connecting pipe 360 ​​is arranged at a second end of the feeding pipe 320, the connecting pipe 360 ​​extends into the feed hopper 210, and the screw 340 is connected to a first end of the feeding pipe 320. 0 is rotatably arranged in the feeding tube 320, the screw 340 rotates to lift the material in the feeding hopper 330 to the connecting tube 360, the motor 350 is arranged at the top of the feeding tube 320, and the motor 350 is connected to the screw 340; the control mechanism includes a sensor 410 and a controller 420, the sensor 410 is arranged in the feeding hopper 210, the sensor 410 is used to detect the material condition of the feeding hopper 210, the sensor 410 is electrically connected to the motor 350, the controller 420 is arranged in the fixing frame 310, and the controller 420 is electrically connected to the sensor 410 and the motor 350 respectively.

[0025] During the working process, the mixer 100 mixes the materials, and the mixed materials enter the hopper 330 from the discharge port to wait for subsequent automatic loading; when the sensor 410 detects that there is no material in the feed hopper 210 or the material is lower than the set value, the sensor 410 feeds back the information to the controller 420, and the controller 420 drives the motor 350 to work, so that the motor 350 drives the screw 340 to rotate, and the screw 340 lifts the material in the hopper 330 into the connecting pipe 360, and finally enters the feed hopper 210, so as to facilitate the operation of the extruder 200. The automatic feeding device for plastic particles described in the embodiment of the present application can realize automatic feeding of materials without manual operation, reduce labor intensity, and improve work efficiency.

[0026] It should be noted that the control method of the controller 420 is only a simple trigger control. Therefore, the control method of the controller 420 does not belong to the protection scope of this application and belongs to the prior art. This application mainly protects the connection relationship between the various components.

[0027] Reference Figure 1 In this embodiment, a fixing plate 220 is provided on the outer wall of the feed hopper 210, and a connecting plate 230 is provided on the fixing plate 220 extending toward the middle of the feed hopper 210, and the sensor 410 is provided on the connecting plate 230. By adopting the above mechanism, it is convenient to install the sensor 410. In this embodiment, a wire groove is vertically provided on the fixing plate 220, and the sensor 410 is provided with a wire, which is located in the wire groove, and the wire is connected to the controller 420. By adopting the above mechanism, the wire can be guided, and the structure is simple and the operation is easy.

[0028] Reference Figure 1 In some embodiments of the present application, the discharge port is provided at the bottom of the mixer 100, so that the material in the mixer 100 can be discharged from the discharge port under the action of gravity, without the need for other mechanisms to cooperate, with a simple structure, and reducing production costs. Further, the discharge port is provided with a discharge pipe 110, the discharge pipe 110 is provided with a discharge valve 120, and the controller 420 is electrically connected to the discharge valve 120. By providing the discharge valve 120, the discharge port can be discharged only when needed, and the controller 420 drives the discharge valve 120 to open or close the discharge pipe 110, without manual operation, with a simple structure and easy operation.

[0029] It is conceivable that the upper hopper 330 is provided with a weighing assembly, which is electrically connected to the discharge valve 120 and the controller 420. When discharging, the material in the upper hopper 330 is weighed by the weighing assembly. When the material in the upper hopper 330 reaches the weight required for production, the weighing assembly feeds back the information to the controller 420, and the controller 420 drives the discharge valve 120 to close the discharge pipe 110, so that quantitative discharging can be achieved, and then quantitative loading can be achieved, thereby improving the scale production level of the product and reducing the production cost.

[0030] Among them, the upper hopper 330 is set to an inverted triangle, and a feeding port is set at the bottom of the upper hopper 330, and the feeding pipe 320 is connected to the feeding port. By setting the upper hopper 330 to an inverted triangle, it is convenient to concentrate the materials at the bottom of the upper hopper 330, thereby improving the feeding efficiency. Specifically, the width of the upper hopper 330 is narrowest below the feeding port, and the width of the upper hopper 330 gradually widens as it extends outward from the bottom of the feeding port. Furthermore, the horizontal cross-section of the upper hopper 330 is a triangle or a trapezoid. The upper hopper 330 is set to a gradually widening triangle or trapezoid, with a larger opening at the top for convenient pouring of raw materials, and a narrower bottom, which is conducive to the concentration of materials near the feeding port for feeding through the screw 340.

[0031] Reference Figure 2 In some embodiments of the present application, the output shaft of the motor 350 is provided with a driving wheel 370, and the screw rod 340 is provided with a driven wheel 380, and the driving wheel 370 and the driven wheel 380 are connected by a belt 390. The motor 350 drives the driving wheel 370 to rotate, so that the driven wheel 380 drives the screw rod 340 to rotate, thereby lifting the material in the upper hopper 330 to the connecting pipe 360, and finally feeding it into the feed hopper 210, so as to realize automatic loading. By adopting the above mechanism, the occupied space can be reduced and the structure can be made reasonable and compact. It should be noted that the motor 350 and the screw rod 340 can also be directly connected through a coupling, or connected through a gear meshing transmission, and the present application does not limit this.

[0032] Reference Figure 1 and Figure 2 It is easy to understand that the bottom of the fixing frame 310 is provided with a roller 311, so that the fixing frame 310 can be moved easily. The roller 311 is provided with a brake. When the position of the fixing frame 310 is confirmed, the roller 311 is locked by the brake to lock the fixing frame 310, so as to prevent the fixing frame 310 from moving due to external force, thereby ensuring the stability and reliability of the equipment.

[0034] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present application.
