Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, and mainly to a centralized feeding device for injection molding materials. Background Technology

[0002] Injection molding is a method of shaping industrial products. Products are usually made using rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding compression molding and die casting. An injection molding machine, also known as an injection machine or injection molding machine, is the main molding equipment that uses plastic molds to make plastic products of various shapes from thermoplastic or thermosetting materials. Injection molding is achieved through injection molding machines and molds. In order to centrally supply materials to multiple injection molding machines during injection molding, many centralized material supply systems for injection molding workshops have emerged in the consumer market.

[0003] However, the centralized material feeding system currently used in injection molding workshops causes materials to fall directly to the bottom of the barrel after being added into the system, which can easily cause blockages at the outlet and thus affect work efficiency. In addition, the current material feeding system is not convenient for centralized drying of materials, which also affects production efficiency. Utility Model Content

[0025] Please refer to the following for details. Figure 1-3 A centralized injection molding material feeding device includes a feed pipe 1, a loading hopper 2 connected to the feed pipe 1, a connecting pipe 3 connected to the loading hopper 2, a diversion pipe 4 connected to the connecting pipe 3, and five discharge pipes 5 connected to the diversion pipes 4. The feed pipe 1 is connected to a suction pump, which can suck material into the loading hopper 2. The discharge pipes 5 are connected to an injection molding machine. The centralized injection molding material feeding device also includes an anti-blocking mechanism, which includes a drive device 6, a transmission shaft 7, and four agitators 8. The drive device 6 is fixed to the top of the loading hopper 2 and is located in the middle of the loading hopper 2. The transmission shaft 7 is located inside the loading hopper 2 and is connected to the output shaft of the drive device 6. The agitators 8 are located inside the loading hopper 2 and are fixed at equal intervals on the transmission shaft 7.

[0026] In this embodiment, the drive device 6 is a geared motor.

[0027] Based on the above technical means: start the drive device 6, drive the transmission shaft 7 to rotate, drive the agitator 8 to rotate, thereby causing the agitator 8 to disperse the material, so as to prevent blockage.

[0028] Furthermore, the feeding hopper 2 consists of an outer layer 201 and an inner layer 202. Both the outer layer 201 and the inner layer 202 are made of stainless steel. The inner layer 202 can be welded or screwed to the inner wall of the outer layer 201. A cavity is formed between the outer layer 201 and the inner layer 202. A heating tube 9 is installed in the cavity to dry the material. The heating tube 9 has a spiral structure and is arranged around the feeding hopper 2.

[0029] Furthermore, the feeding hopper 2 is equipped with a variety of sensors, namely a material position sensor 10 and a temperature sensor 11. The material position sensor 10 is installed near the top of the feeding hopper 2 and is used to detect the remaining material inside the feeding hopper 2. If the material position is lower than the material position sensor 10, the suction pump will start to add material to the feeding hopper 2 to achieve automatic feeding. There are multiple temperature sensors 11 installed at intervals on the inner wall of the feeding hopper 2. The temperature sensors 11 can detect the temperature inside the feeding hopper 2 so as to better control the temperature inside the feeding hopper 2.

[0030] Furthermore, a control valve 12 and a flow meter 13 are installed on the feed pipe 5. The control valve 12 is a solenoid valve, so the material flow rate can be controlled by the control valve 12 and the flow meter 13.

[0031] Furthermore, it also includes a controller 14, which is fixed on the outer wall of the feeding hopper 2. The drive device 6, heating tube 9, material position sensor 10, temperature sensor 11, control valve 12 and flow meter 13 are all electrically connected to the controller 14. The controller 14 is used to control the operation of each electrical appliance.

[0032] Furthermore, a long strip of transparent observation window 15 is provided on the feeding hopper 2. The transparent observation window 15 is made of quartz glass and is embedded in the feeding hopper 2 to facilitate the staff to observe the internal situation of the feeding hopper 2.

[0033] Furthermore, a guide plate 203 inclined from the outside to the middle is provided at the bottom of the feeding hopper 2. The guide plate 203 plays a guiding role, so that as much material as possible inside the feeding hopper 2 is discharged from the feeding hopper 2, thus achieving the purpose of discharging all the material.

[0034] Furthermore, an insulation layer 204 is provided on the outer wall of the outer layer 201. The insulation layer 204 can be an aluminum silicate insulation layer 204. The insulation layer 204 can lock in the heat generated by the heating tube 9 and reduce energy consumption.

[0035] In this embodiment, the drive shaft 7, the stirring paddle 8, and the guide plate 203 are all made of high-temperature resistant materials. By using high-temperature resistant materials, it is possible to effectively prevent the materials from deforming under high-temperature conditions for a long time during use, thus preventing them from being used normally.

[0036] This utility model relates to a centralized feeding device for injection molding materials, and its working principle is explained in conjunction with the accompanying drawings:

[0037] The material is sucked from the material pile into the feeding hopper 2 through the feed pipe 1 by the suction pump. The drive device 6 starts and drives the transmission shaft 7 and the stirring paddle 8 to rotate, thereby stirring the material and preventing blockage. At the same time, the heating pipe 9 heats and dries the material. The dried material flows through the connecting pipe 3 and the diversion pipe 4 into different discharge pipes 5, and finally enters the injection molding machine.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
