[0002] Injection molding raw materials, as an indispensable core material for the production of plastic products, are actually a polymer, a type of synthetic resin. Its appearance is quite similar to natural pine resin, but after specific processing, it can show completely different characteristics and uses. In the production process of plastic products, injection molding raw materials play a vital role.

[0003] The raw materials for injection molding are carefully selected and proportioned to ensure that their quality is stable and meets production requirements. Subsequently, these raw materials need to be dried by professional drying equipment. The drying process is crucial, as it can effectively remove moisture and impurities from the raw materials to ensure the purity and stability of the raw materials. The performance of the raw materials for injection molding that have been dried will be significantly improved, thereby ensuring the quality of the final plastic products. Next, the dried raw materials for injection molding will be fed into the injection molding machine.

[0004] A drying device is disclosed in the patent "A drying device for injection molding machines" (publication number CN208645849U, hereinafter referred to as prior art 1). The drying device in prior art 1 is provided with a drying device and a drying box, and a heating plate is provided inside the drying box. The material is placed on the heating plate to dry the material, and double drying is performed by the drying device and the heating plate. After drying, it is circulated through the air outlet pipe. However, since the material cannot move in the drying box, only the surface of the material can be dried, and the internal position cannot be dried, resulting in poor drying effect. In addition, not only the moisture in the raw material and the heat in the device will be discharged into the surrounding environment with the airflow, but also some dust in the raw material will enter the surrounding environment with the airflow, causing the surrounding environment to be polluted by heat and dust.

[0011] Beneficial Effects

[0013] The injection molding material drying device, through the cooperation between the first material guide plate, the second material guide plate, the first through hole and the second through hole, with the cooperation of the multiple staggered first material guide plates and the second material guide plates, makes the injection molding material continuously roll and fall in the drying box, and the falling speed is slowed down.

The injection molding material drying device, through the cooperation between the bending exhaust pipe, the water storage box, the exhaust pipe, the water inlet pipe and the drain pipe, can make the dust and heat contained in the hot air flow passing through the injection molding material be absorbed by the cold water in the water storage box, which can prevent the dust in the air flow from entering the surrounding environment, and can also reduce the heat in the air flow from entering the surrounding environment, reducing the impact on the surrounding environment during the operation of the device.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1

[0021] like Figure 1As shown, the utility model provides an injection molding raw material drying device, including a drying box 1 and a water storage box 11, a feed pipe 2 is fixedly connected to the top of the drying box 1, a first material guide plate 4 and a second material guide plate 5 are fixedly connected to the inner wall of the drying box 1, a discharge port 3 is arranged at the bottom of the drying box 1, and a first through hole 6 is opened on the drying box 1. Figure 2 As shown, the outer surface of the drying box body 1 is fixedly connected to a fixed shell body 7, a second through hole 8 is opened on the fixed shell body 7, a hot air blower 9 is fixedly connected to the outer surface of the fixed shell body 7, a bent exhaust pipe 10 is fixedly connected to the side of the drying box body 1 away from the fixed shell body 7, a water inlet pipe 12 and a drain pipe 13 are fixedly connected to the outer surface of the water storage tank body 11, a one-way valve 14 is fixedly connected to the water inlet pipe 12 and the drain pipe 13, and an exhaust pipe 15 is fixedly connected to the top of the water storage tank body 11.

[0022] like Figure 4 As shown, the first material guide plate 4 and the second material guide plate 5 are arranged below the feed pipe 2, and the first material guide plate 4 and the second material guide plate 5 are respectively arranged on opposite sides of the drying box body 1, and the first material guide plate 4 and the second material guide plate 5 are arranged alternately.

[0023] like Figure 3 and Figure 4 As shown, there are a plurality of first through holes 6 and a plurality of second through holes 8 , the first through holes 6 are aligned with the second through holes 8 , and the interior of the drying box 1 is connected to the interior of the fixed shell 7 through the first through holes 6 and the second through holes 8 .

[0024] Specifically, the outer surface of the bent exhaust duct 10 is fixedly connected to the top of the water storage tank 11, and the outer surface of the bent exhaust duct 10 passes through the water storage tank 11 and extends to the inner cavity. The shape and length of the bent exhaust duct 10 can be adjusted according to actual needs to optimize the heat recovery effect and cooling efficiency. Its outer surface is fixedly connected to the top of the water storage tank 11, which ensures the stability and sealing of the connection and prevents hot air leakage. At the same time, the outer surface of the bent exhaust duct 10 passes through the water storage tank 11 and extends to the inner cavity, so that the hot air can fully exchange heat with the water in the water storage tank 11, further improving the heat recovery efficiency.

[0025] Specifically, the interior of the bent exhaust duct 10 is connected to the interior of the drying box 1 , and the water inlet pipe 12 is arranged right above the drain pipe 13 .

[0026] The working principle and beneficial effects of the above embodiments:

[0027] like Figure 2 and Figure 4As shown, when in use, the injection molding material falls from the feed pipe 2 onto the top first guide plate 4, then falls along the first guide plate 4 onto the second guide plate 5, and then falls along the second guide plate 5 onto the next first guide plate 4 until it is discharged from the discharge port 3. During this process, the hot air flow generated by the hot air blower 9 enters the fixed shell 7, and then passes through the second through hole 8 and the first through hole 6 into the drying box 1, so that the hot air flow blows toward the injection molding material falling along the first guide plate 4 and the second guide plate 5. Since the injection molding material continuously rolls and falls in the drying box 1, and the multiple first guide plates 4 and the second guide plates 5 can slow down the falling speed of the injection molding material, the hot air flow can fully contact the injection molding material, so that the injection molding material is fully dried. The hot air flow that passes through the injection molding raw material takes away the moisture and dust in the injection molding raw material and enters the bent exhaust pipe 10, and cold water is injected into the water storage tank 11 through the water inlet pipe 12, so that the liquid level of the cold water is higher than the bottom of the bent exhaust pipe 10, and the hot air flow containing moisture and dust enters the cold water in the water storage tank 11 along the bent exhaust pipe 10, and the cold water is used to absorb the heat and dust in the air flow, and the cooled and dust-removed air flow is discharged from the exhaust pipe 15 into the surrounding environment, which can prevent the dust in the air flow from entering the surrounding environment and reduce the heat in the air flow from entering the surrounding environment. After the cold water in the water storage tank 11 absorbs enough heat and becomes hot, the drain pipe 13 can be opened to discharge the hot water, and then new cold water is introduced through the water inlet pipe 12.
