Description

Technical Field

[0001] This utility model relates to a rotational molding machine, specifically a novel electromagnetic heating rotational molding machine. Background Technology

[0002] Rotational molding is a method of shaping plastic raw materials by placing them in a mold and rotating and heating them. Electromagnetic heating rotational molding machines use the principle of electromagnetic induction to heat and plasticize plastic. During operation, electricity is supplied through a power line, and the current passes through a coil to generate a magnetic field. This magnetic field acts on the plastic mold, causing it to heat up and plasticize.

[0003] In order to achieve the rotation of the material, the existing electromagnetic heating rotational molding machine requires the insulated furnace (usually cylindrical) containing the material to be turned over, thereby driving the material inside to rotate. Since the insulated furnace is large in size and mass, a huge drive structure is required to drive it to rotate. This consumes a lot of electricity during use, which is not conducive to energy conservation and environmental protection. Utility Model Content

[0004] The purpose of this invention is to provide a new type of electromagnetic heating rotational molding machine, which has the advantages of energy saving and environmental protection. It only requires a small amount of electricity to drive its rolling and rotation, which helps to greatly reduce the use of electricity and save power resources.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel electromagnetic heating rotational molding machine includes a support frame and a heat preservation furnace fixed on the support frame. The heat preservation furnace is equipped with a circulation mechanism and an extrusion mechanism located on one side of the circulation mechanism. The circulation mechanism includes a circulation fan, a first feeding pipe connected to the circulation fan, and an electromagnetic heater located below the circulation fan. A second feeding pipe and a molding component are provided at the end of the electromagnetic heater away from the circulation fan. The second feeding pipe is fixed on the support frame. The molding component includes a receiving pipe and a receiving box fixed on the receiving pipe. A molding frame is fixed on the upper surface of the receiving box. The molding frame is fixed to the bottom of the heat preservation furnace. The extrusion mechanism includes a crossbeam plate and two sets of rollers arranged on the crossbeam plate. The two sets of rollers are symmetrically arranged at both ends of the crossbeam plate, and connecting frames are fixedly connected to the two sets of rollers respectively. Extrusion gates are connected to the lower parts of the two sets of connecting frames respectively.

[0006] Preferably, the circulating fan is fixed to the upper end face of the electromagnetic heater, the electromagnetic heater is fixed to the upper end face of the second feeding pipe, and the second feeding pipe is fixed to the support frame.

[0007] Preferably, the end of the first feeding pipe away from the circulating fan is fixed to the top of the heat preservation furnace, and the first feeding pipe communicates with the cavity of the heat preservation furnace.

[0008] Preferably, the end of the receiving tube away from the receiving box extends into the cavity of the second feeding tube, and the receiving tube is fixed inside the second feeding tube. The shaping frame is provided with a plurality of shaping openings, which are evenly distributed on the shaping frame.

[0009] Preferably, the circulation mechanism further includes a protective shell, which is fixed on the support frame and disposed on the outside of the first feeding pipe.

[0010] Preferably, the extrusion mechanism further includes a plurality of stabilizing rods, all of which are fixed to the crossbeam plate, and both the stabilizing rods and the crossbeam plate are fixed to the support frame.

[0011] Preferably, the two extrusion gates are arranged symmetrically, and each extrusion gate is provided with a number of extrusion ports.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, through the set circulation mechanism and the heat-preserving furnace, after the material is added to the heat-preserving furnace, it is sucked into the first feeding pipe under the action of the circulating fan and the electromagnetic heater. Then, it enters the electromagnetic heater through the circulating fan, and then enters the shaping component under the action of the second feeding pipe, finally returning to the cavity of the heat-preserving furnace to complete the heating of the material. Because an electromagnetic heater is used for furnace heating, compared with the commonly used gas (natural gas and heating elements) in the prior art, this solution does not produce pollutants, thus being more environmentally friendly and saving energy. Furthermore, the electromagnetic heater, combined with the circulation mechanism, will not burn out during use, making it safer. Attached Figure Description

[0023] Please see Figure 2 The circulation mechanism 3 includes a circulation fan 31, a first feeding pipe 32 connected to the circulation fan 31, and an electromagnetic heater 33 disposed below the circulation fan 31. The end of the first feeding pipe 32 away from the circulation fan 31 is fixed to the top of the heat preservation furnace 2, and the first feeding pipe 32 communicates with the cavity of the heat preservation furnace 2. The end of the electromagnetic heater 33 away from the circulation fan 31 is provided with a second feeding pipe 34 and a molding component 35. The circulation fan 31 is fixed to the upper end face of the electromagnetic heater 33, the electromagnetic heater 33 is fixed to the upper end face of the second feeding pipe 34, and the second feeding pipe 34 is fixed to the support frame 1.

[0024] Please see Figure 3 The molding component 35 includes a receiving pipe 351 and a receiving box 352 fixed on the receiving pipe 351. A molding frame 353 is fixed on the upper end face of the receiving box 352. The molding frame 353 is fixed to the bottom of the heat preservation furnace 2. One end of the receiving pipe 351 away from the receiving box 352 extends into the cavity of the second feeding pipe 34, and the receiving pipe 351 is fixed inside the second feeding pipe 34. The molding frame 353 is provided with a plurality of molding ports 3531, which are evenly distributed on the molding frame 353 and are all connected to the cavity of the heat preservation furnace 2.

[0025] Please see Figure 4 The circulation mechanism 3 also includes a protective shell 36, which is fixed on the support frame 1 and is located on the outside of the first feeding pipe 32.

[0026] Please see Figure 5 The extrusion mechanism 4 includes a crossbeam plate 41 and two sets of roller groups 42 disposed on the crossbeam plate 41. The two sets of roller groups 42 are symmetrically disposed at both ends of the crossbeam plate 41, and connecting frames 43 are fixedly connected to the two sets of roller groups 42 respectively. Extrusion gates 44 are respectively connected to the bottom of the two sets of connecting frames 43. The extrusion mechanism 4 also includes multiple stabilizing rods 45. The multiple stabilizing rods 45 are all fixed to the crossbeam plate 41, and the multiple stabilizing rods 45 and the crossbeam plate 41 are all fixed to the support frame 1.

[0027] Please refer to the following: Figures 1 to 5In the operation of this utility model, the two sets of rollers 42 are first moved away from each other, which in turn moves the two extrusion gates 44 away from each other, thereby opening the cavity opening of the heat preservation furnace 2. The material to be plasticized is added into the cavity of the heat preservation furnace 2. Then, the two extrusion gates 44 close the cavity opening of the heat preservation furnace 2. The electromagnetic heater 33 and the circulating fan 31 are driven to work. The electromagnetic heater 33 releases heat, which enters the cavity of the heat preservation furnace 2 through the second feeding pipe 34 to heat the material. This heat then drives the material through the first feeding pipe 32 into the circulating fan 31, and then into the electromagnetic heater 33. The material is then sent to the molding component 35 through the second feeding pipe 34, and finally released from several molding ports 3531 and re-enters the cavity of the heat preservation furnace 2. This achieves the rolling and rotation of the material. At the same time, the heating structure works to heat the environment inside the cavity of the heat preservation furnace 2, so that the material is heated and plasticized. After plasticization, the material is extruded through several extrusion ports 441 (the extrusion method is existing technology and will not be described in detail here).
