[0001] The utility model relates to the technical field of foam plastic production, in particular to an EPP foam plastic mold filling device. Background Art

[0002] EPP (expanded polypropylene) foam is a lightweight, high-strength material with excellent thermal insulation, impact resistance, and cushioning properties. Due to its excellent physical properties, EPP foam is widely used in packaging, automotive, construction, electronics, and sporting goods. The mold filling device is a crucial piece of equipment in the EPP foam production process. Its primary function is to evenly fill the EPP raw material into the mold, thereby ensuring the quality and consistency of the molded product.

[0003] Currently, most foam plastic mold filling devices, when in use, usually convey raw materials into a feeding gun through a hopper and use the feeding gun for filling. However, there is no stirring mechanism at the bottom of the hopper, so there are the following disadvantages: the raw materials inside the hopper may become clogged at its bottom, resulting in an inability to continuously supply raw materials, reducing filling efficiency and quality. Utility Model Content

[0004] The purpose of the utility model is to provide an EPP foam plastic mold filling device to solve the problem that the raw materials inside the hopper may be blocked at the bottom, resulting in the inability to continuously supply the raw materials and reducing the filling efficiency and quality.

[0006] Preferably, a mounting plate is detachably provided on the top surface of the hopper, a second drive motor is fixed to the top surface of the mounting plate, a second rotating shaft is fixed to the output shaft of the second drive motor, and two first stirring plates are respectively fixed to the front and rear sides of the outer wall of the second rotating shaft.

[0007] Preferably, a mounting hole is respectively opened on one side of the two first stirring plates, and a second stirring plate is rotatably arranged inside the two mounting holes.

[0008] Preferably, the top surface of the hopper is provided with two threaded grooves, and the top surface of the mounting plate is provided with two threaded holes, the two threaded holes are respectively threadedly connected with bolts, and the threaded ends of the two bolts are respectively connected to the internal threads of the two threaded grooves.

[0009] Preferably, heating plates are fixed on the left and right sides of the inner wall of the feeding gun, respectively, and the heating plates are electrically connected to the PLC controller.

[0010] Preferably, a connection hole is provided on the top surface of the feeding gun, a temperature sensor is fixed inside the connection hole, and the temperature sensor is electrically connected to the PLC controller.

[0011] Compared with the prior art, the EPP foam plastic mold filling device using the above technical solution has the following beneficial effects:

[0012] 1. During use, the first drive motor, the first rotating shaft and the rotating plate effectively prevent the sedimentation and clogging of the raw materials at the bottom of the hopper, and also ensure the continuous supply of raw materials, further improving the filling efficiency and quality;

[0013] 2. During use, the second shaft is rotated by starting the second drive motor, so that the first stirring plate can stir the raw materials inside the hopper, which not only ensures the full mixing of the raw materials, but also improves the uniformity and fluidity of the raw materials. When the first stirring plate stirs the raw materials inside the hopper, the second stirring plate and the raw materials have more direct contact and friction, thereby stirring them a second time. This secondary stirring not only further enhances the mixing effect of the raw materials, but also ensures that the raw materials are fully dispersed inside the hopper. During use, bolts facilitate the staff to disassemble and assemble the mounting plate, and thus facilitate the disassembly and assembly of the second drive motor, the first stirring plate, and the second stirring plate, which not only facilitates the maintenance and care of the equipment, but also improves the flexibility and scalability of the equipment;

[0014] 3. During use, the heating plate heats the interior of the feed gun, allowing the raw materials inside the feed gun to maintain their fluidity and plasticity at an appropriate temperature. The temperature sensor monitors the temperature inside the feed gun in real time and feeds the data back to the PLC controller. The PLC controller adjusts the operating status of the heating plate based on the feedback data, thereby achieving precise control of the internal temperature of the feed gun. This temperature monitoring and control system not only ensures the optimal temperature of the raw materials during the extrusion and filling process, but also improves the reliability and safety of the equipment.

[0020] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] like Figures 1-4 As shown, an EPP foam plastic mold filling device includes a feeding gun 1, which is fixed to the top surface of a base 2, a mounting box 3 is fixed to the top surface of the base 2, a PLC controller is fixed to the right side of the base 2, an extrusion motor 4 is fixed inside the mounting box 3, the output shaft of the extrusion motor 4 passes through the mounting box 3 and extends into the feeding gun 1, an extrusion screw 5 is rotatably provided inside the feeding gun 1, the rear end of the extrusion screw 5 is fixedly connected to the output shaft of the extrusion motor 4, a feeding hole 6 is provided on the top surface of the feeding gun 1, a hopper 7 is fixed inside the feeding hole 6, a rotating hole 8 is provided on the right side of the outer wall of the hopper 7, a first driving motor 9 is fixed to the right side of the outer wall of the hopper 7, the output shaft of the first driving motor 9 is rotatably provided in the rotating hole 8, the output shaft of the first driving motor 9 is fixed to a first rotating shaft 10, and a rotating plate 11 is respectively fixed to the front and rear sides of the outer wall of the first rotating shaft 10.

[0022] During use, the staff first places the front end of the feeding gun 1 into the filling hole of the mold, and then the EPP foam plastic raw material inside the hopper 7 enters the feeding gun 1 through the feed hole 6, and then starts the extrusion motor 4 to rotate the extrusion screw 5 to fill the raw material in the feeding gun 1 into the mold. At the same time, the staff starts the first drive motor 9 to rotate the first rotating shaft 10 and the rotating plate 11, thereby stirring the raw material at the bottom of the hopper 7.

[0023] The first drive motor 9, the first rotating shaft 10 and the rotating plate 11 effectively prevent the raw materials from settling and clogging at the bottom of the hopper 7, and ensure the continuous supply of raw materials, thereby further improving the filling efficiency and quality.

[0024] like Figures 1-4 As shown, the top surface of the hopper 7 is detachably provided with a mounting plate 12, the top surface of the mounting plate 12 is fixed with a second drive motor 13, the output shaft of the second drive motor 13 is fixed with a second rotating shaft 14, and two first stirring plates 15 are respectively fixed on the front and rear sides of the outer wall of the second rotating shaft 14.

[0025] During use, by starting the second drive motor 13 to rotate the second shaft 14, the first stirring plate 15 can stir the raw materials inside the hopper 7, which not only ensures the full mixing of the raw materials, but also improves the uniformity and fluidity of the raw materials.

[0027] During use, when the first stirring plate 15 stirs the raw materials in the hopper 7, the second stirring plate 17 and the raw materials are in more direct contact and friction, thereby performing secondary stirring. This secondary stirring not only further enhances the mixing effect of the raw materials, but also ensures that the raw materials are fully dispersed in the hopper 7. The bolts 20 facilitate the disassembly and assembly of the mounting plate 12 by the staff, thereby facilitating the disassembly and assembly of the second drive motor 13, the first stirring plate 15, and the second stirring plate 17, which not only facilitates the maintenance and upkeep of the equipment, but also improves the flexibility and scalability of the equipment.

The temperature sensor 23 facilitates real-time monitoring of the temperature inside the feed gun 1 and feeds the data back to the PLC controller. The PLC controller adjusts the operating state of the heating plate 21 based on the feedback data, thereby achieving precise control of the temperature inside the feed gun 1. This temperature monitoring and control system not only ensures the optimal temperature state of the raw materials during the extrusion and filling process, but also improves the reliability and safety of the equipment.
