Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of injection molding cup production equipment, specifically to a feeding and heat preservation device and injection molding cup production equipment. Background Technology
[0002] Plastic cups are a common daily necessity. Because they are usually made by injection molding, they are also called injection molded cups. Injection molding is a process in which various raw materials are mixed in a certain proportion, heated to a molten state, and then poured into a mold. After cooling and solidification, the mold is demolded. The feeding device is an important component of injection molding equipment.
[0003] In the prior art, patent application CN202420076876.3 discloses a feeding device for an injection molding machine, including a bottom material storage device, an intermediate transmission device, a support device, and an end discharge device. The bottom material storage device includes a material storage box with a support column fixedly connected to its bottom end. The intermediate transmission device includes a transmission shell with a conveying pipe connecting it to the material storage box. A discharge pipe is provided at the discharge end of the transmission shell, and a motor is fixedly installed at its bottom end. A transmission auger is fixedly connected to the output end of the motor. The support device includes a base plate with a support column fixedly connected to its bottom end and a support block and two fixed plates fixedly connected to its top end. The support block is fixedly connected to the transmission shell. The end discharge device includes two fixed blocks. This feeding device allows for convenient and rapid adjustment of the discharge position, making it more widely applicable and highly practical, thus facilitating practical applications.
[0004] The existing injection molding machine feeding device can also be used as the feeding device for injection molded cup production equipment. The storage box is generally placed indoors in the material warehouse, while the injection molding machine is placed in the processing workshop. The transfer shell plays the role of conveying in the middle. Therefore, the middle part of the transfer shell is often located outdoors between the material warehouse and the processing workshop.
[0005] However, the current injection molding machine feeding device lacks a heat preservation device in the transfer shell. When the outdoor temperature is low and the length of the transfer shell is long, the time required for the raw material to be transported from the storage box in the material warehouse to the injection molding machine in the production workshop will be long. This causes the raw material to gradually cool down during the transportation process, which makes the time required to heat it to the molten state after it is transported to the injection molding machine longer, thus reducing production efficiency.

[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] The feeding and heat preservation device and injection molding cup production equipment proposed in this utility model have the following characteristics: when the water in the water storage tank flows through each set of heat preservation pipes, it transfers its own temperature to the heat preservation tank and then to the transmission shell.

When the material is transported in the transmission shell, the transmission shell itself, which has a high temperature, can play a role in keeping the material warm. It can even preheat the material as needed, thereby shortening the heating time required after the material enters the injection molding machine and increasing production efficiency.

[0024] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0025] Example 1: Please refer to Figures 1 to 6This utility model provides a technical solution: a feeding and heat preservation device, comprising: a feeding device body 1 for an injection molding machine, a transmission shell 2 disposed in the feeding device body 1, a heat preservation groove 3 formed in the inner wall of the transmission shell 2, a plurality of sets of heat preservation pipes 4 disposed in the heat preservation groove 3, one set of heat preservation groove 3 connected to a water inlet conveying pipe 7, another set of heat preservation groove 3 connected to a water return conveying pipe 9, the other ends of the water inlet conveying pipe 7 and the water return conveying pipe 9 connected to the same set of water storage tanks 10, a heater mounting head 11 and a plurality of sets of heating devices disposed in the water storage tanks 10, the heat preservation groove 3 having an annular groove structure, the heat preservation pipes 4 having an annular pipe structure, and the plurality of sets of heat preservation pipes 4 being linearly distributed in the heat preservation groove 3, adjacent to each other. The two sets of insulation pipes 4 are connected by the same set of connecting pipes 5. One set of insulation pipes 4 is connected to a water inlet pipe 6, and the other set of insulation pipes 4 is connected to a water return pipe 8. The water inlet pipe 6 and the water return pipe 8 are respectively movably inserted into one end of the water inlet delivery pipe 7 and the water return delivery pipe 9. Screw holes are opened at the mating positions of the water inlet pipe 6 and the water inlet delivery pipe 7, and the same screw is installed in the screw holes of the water inlet pipe 6 and the water inlet delivery pipe 7. Similarly, screw holes are opened at the mating positions of the water return pipe 8 and the water return delivery pipe 9, and the same screw is installed in the screw holes of the water return pipe 8 and the water return delivery pipe 9. One end of the water inlet delivery pipe 7 connected to the water storage tank 10 is connected to the heater mounting head 11.
[0026] In actual use, before using the injection molding machine feeding device body 1 to feed the injection molding machine, several sets of heating devices in the water storage tank 10 are powered on according to requirements. After being powered on, the heating devices heat the water stored in the water storage tank 10. After heating to the required temperature, the heater mounting head 11 is turned on to pump the water in the water storage tank 10 into the water inlet pipe 7. The water flows through the water inlet pipe 7 and the water inlet pipe 6 into one set of insulation pipes 4. After filling the insulation pipe 4, it flows through the connecting pipe 5 into the other sets of insulation pipes 4. Finally, it flows out from the insulation pipe connected to the return water pipe 8. After the water flows through the return water pipe 8 and the return water conveying pipe 9, it flows back to the water storage tank 10. When the water in the water storage tank 10 flows through each set of insulation pipes 4, it transfers its own temperature to the insulation tank 3 and then to the transmission shell 2. After the temperature of the transmission shell 2 rises, the material is fed by the main body 1 of the injection molding machine feeding device. When the material is transferred in the transmission shell 2, the transmission shell 2, which has a high temperature, can keep the material warm. It can even preheat the material as needed, thereby shortening the heating time required after the material enters the injection molding machine and increasing production efficiency.
[0027] Example 2: Based on Example 1, in order to heat the water in the water storage tank 10 through a heating device, the heating device includes: a heater mounting head 11 and a high-temperature resistance wire and a circuit rod 12. The heater mounting head 11 is movably inserted into the surface of the water storage tank 10. The high-temperature resistance wire and the circuit rod 12 are fixed at one end of the heater mounting head 11 that extends into the water storage tank 10. The other end of the heater mounting head 11 is connected to a cable 15. A plug is provided at the other end of the cable 15. The high-temperature resistance wire and the circuit rod 12 are electrically connected to the cable 15. A sealing ring 14 is provided in the inner wall of the water storage tank 10. The sealing ring 14 has an annular plate structure. The inner ring of the sealing ring 14 abuts against the surface of the heater mounting head 11. A water-proof shell 13 is fixed at one end of the heater mounting head 11 that extends into the water storage tank 10. The water-proof shell 13 is sleeved on the surface of the high-temperature resistance wire and the circuit rod 12.
[0028] When the heating device is needed to heat the water in the water storage tank 10, the plug of the cable 15 is plugged in. After the cable 15 supplies power to the high-temperature resistance wire and the circuit rod 12, the current will cause the high-temperature resistance wire and the circuit rod 12 to generate high heat due to the large resistance. The heat of the high-temperature resistance wire and the circuit rod 12 is transferred to the water in the water storage tank 10 through the water-proof shell 13, thereby achieving the function of heating the water in the water storage tank 10. In addition, the water-proof shell 13 plays a role in preventing water from entering the water. The sealing ring 14 set on the inner wall of the water storage tank 10 is made of rubber and seals the gap between the heater mounting head 11 and the water storage tank 10, thereby preventing water leakage.
[0029] In actual use, before using the injection molding machine feeding device body 1 to feed the injection molding machine, several sets of heating devices in the water storage tank 10 are powered on according to requirements. The powered heating devices heat the water stored in the water storage tank 10. After heating to the required temperature, the heater mounting head 11 is turned on to pump the water in the water storage tank 10 into the inlet water delivery pipe 7. The water flows through the inlet water delivery pipe 7 and the inlet pipe 6 into one set of insulation pipes 4. After filling the insulation pipe 4, it flows through the connecting pipe 5 into the other sets of insulation pipes 4. Finally, it flows from the insulation pipe 4 connected to the return water pipe 8 through the return water pipe 8 and the return water delivery pipe 9 back to the water storage tank 10. When the water in the water storage tank 10 flows through each set of insulation pipes 4, it transfers its own temperature to the insulation tank 3 and then to the transfer shell 2. After the temperature of the transfer shell 2 rises, the injection molding machine feeding device body 1 is used to feed the material. The material then has a high temperature during transmission in the transfer shell 2. The temperature transmission shell 2 can keep the material warm and can even preheat the material as needed, thereby shortening the heating time required after the material enters the injection molding machine and increasing production efficiency. When the heating device is needed to heat the water in the water storage tank 10, the plug of the cable 15 is plugged in. After the cable 15 supplies power to the high-temperature resistance wire and the return rod 12, the current will cause the high-temperature resistance wire and the return rod 12 to generate high heat due to the large resistance. The heat of the high-temperature resistance wire and the return rod 12 is transferred to the water in the water storage tank 10 through the water-proof shell 13, thereby achieving the function of heating the water in the water storage tank 10. In addition, the water-proof shell 13 plays a role in preventing water from entering the water. The sealing ring 14 set on the inner wall of the water storage tank 10 is made of rubber and seals the gap between the heater mounting head 11 and the water storage tank 10, thereby preventing water leakage.
