Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to an injection molding machine with drying equipment. Background Art

[0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal, and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it eject and fill the mold cavity. The working principle of the injection molding machine is similar to that of a syringe for injection. It uses the thrust of a screw or a plunger to inject the plasticized molten state, i.e., the viscous flow state, into a closed mold cavity. After solidification and finalization, the product is obtained. The quality of the raw materials has a great impact on the quality of the injection molded product. Influence, some raw materials agglomerate after being damp and squeezed during storage, affecting the subsequent melting process and processing and molding process, and causing adverse effects on the quality of injection molded products. Therefore, the raw materials need to be preheated and dried, but the existing technology usually uses a drying drum for drying. When in use, the dried raw materials need to be transferred separately into the funnel on the injection molding machine for melting processing, which is time-consuming and labor-intensive, and increases the user's workload. In addition, during the drying process, the inlet temperature and the outlet temperature are too high, which easily causes energy waste. Therefore, it is particularly important to design an injection molding machine with a drying device to solve the above-mentioned defects. Utility Model Content

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] Example:

[0028] The embodiment of the utility model provides an injection molding machine with a drying device, which aims to solve the technical problem that the drying device in the prior art cannot directly transport raw materials into the injection molding machine for melting according to demand while drying.

[0029] The utility model provides a technical solution:

[0030] First, see Figure 1-Figure 5An injection molding machine with a drying device comprises an injection molding machine body 1 and a drying device 2. The drying device 2 is used to preheat and dry the injection molding raw materials. The drying device 2 comprises a feed bin 201 and a discharge hopper 202 located at one end of the feed bin 201. After the user puts the raw materials into the feed bin 201 for drying, the raw materials are directly transported into the injection molding machine body 1 through the discharge hopper 202 for melting. A square plate 2011 is installed at one end of the feed bin 201 close to the discharge hopper 202. An empty slot is opened inside the feed bin 201 at a position corresponding to the square plate 2011. A screw rod 3 is installed on one side of the feed bin 201. The screw rod 3 passes through the empty slot and extends to the inside of the square plate 2011. The user rotates the screw rod 3 to rotate the screw rod 3. Rod 3 makes the square plate 2011 move, and moves the square plate 2011 in and out of the empty slot to control the quantitative delivery of raw materials. An embedded groove is opened on the outer side of one end of the screw rod 3, and a limiting block is connected to the position of the embedded groove corresponding to the feeding bin 201, and the limiting block is installed to match the embedded groove. A turning handle is connected to the end of the screw rod 3 away from the square plate 2011, and the side of the square plate 2011 away from the screw rod 3 is beveled. One side of the feeding bin 201 is installed to match the beveled side of the square plate 2011. The screw rod 3 is rotated by the turning handle outside the feeding bin 201. Because of the design of the limiting block and the embedded groove, the screw rod 3 will not gradually rotate out of the feeding bin 201 as the user rotates, and can only rotate in situ.

[0031] For further information, see Figure 2 and Figure 4 , a heat dissipation fan is installed on the side of the feeding bin 201 away from the discharging funnel 202, and a hot air blower 4 is installed on the side of the feeding bin 201 away from the discharging funnel 202. An air gathering groove is provided inside the feeding bin 201 and at the position of the hot air blower 4. The hot air blower 4 is turned on, and the hot air enters the stirring rod 5 through the air gathering groove. The hot air blower 4 is turned on to heat the inside of the feeding bin 201. When the internal temperature of the feeding bin 201 reaches a certain height, the heat dissipation fan is turned on to cool the internal temperature to prevent the raw materials from melting due to excessive temperature. A motor 2012 is connected to the side of the feeding bin 201 away from the discharging funnel 202, and a card slot is provided on one side of the feeding bin 201 and at the lower side of the air gathering groove. A first rotating wheel and a second rotating wheel are installed inside the card slot. The driving end of the motor 2012 is fixedly connected to the first rotating wheel, and a conveyor belt is sleeved between the first rotating wheel and the second rotating wheel. The motor 2012 is turned on to rotate the first rotating wheel, and the first rotating wheel causes the second rotating wheel to rotate synchronously through the conveyor belt.

[0032] Among them, see Figure 2 and Figure 4A stirring rod 5 is installed inside the feed bin 201. The interior of the stirring rod 5 is designed as a hollow structure. The end of the stirring rod 5 away from the discharge funnel 202 is fixedly connected to the second rotating wheel. The stirring rod 5 passes through the second rotating wheel and extends to the inside of the wind gathering groove. When the second rotating wheel rotates, the stirring rod 5 is driven to rotate at the same time. The hot air is transmitted into the interior of the silo 201 through the internal transmission of the stirring rod 5. As the stirring rod 5 rotates, the hot air evenly dries the internal raw materials. The air outlet of the stirring rod 5 is connected with a filter to prevent the injection molding raw materials from entering the stirring rod 5 during the stirring process. When the user opens the square plate 2011 to convey the raw materials, the stirring rod 5 rotates at the same time to ensure the uniform conveying of the raw materials at different positions.

[0033] For further information, see Figure 2 and Figure 5 A discharge plate 6 is installed on the side of the feeding bin 201 away from the discharge funnel 202, and a first opening groove is provided in the feeding bin 201 and at the position of the discharge plate 6, so that one side of the discharge plate 6 can be embedded in the feeding bin 201 for storage, and second opening grooves are provided on both sides of the first opening groove, and a third opening groove is provided at the position of the discharge plate 6 corresponding to the second opening groove, and a spring 601 is connected inside the third opening groove, and a fixed block is connected to one end of the spring 601 away from the third opening groove, and the side of the fixed block away from the feeding bin 201 is beveled, and the discharge plate 6 is pushed into the feeding bin 201, and the fixed block is pushed in due to the rebound force of the spring 601 The second opening groove is inserted to fix the discharge plate 6 and the feeding bin 201. A slide groove 602 is provided on one side of the discharge plate 6. After the discharge plate 6 is opened, the user rotates the discharge plate 6 and puts the slide groove 602 against the side of the feeding bin 201. At this time, one side of the slide groove 602 is against the feeding bin 201, so that the discharge plate 6 is fixed on the feeding bin 201, and the discharge plate 6 is simply stored. A pulley is installed at the position of the slide groove 602 on one side of the feeding bin 201 corresponding to the side of the feeding bin 201. A handle is connected to the side of the discharge plate 6 away from the first opening groove. The user moves the discharge plate 6 through the handle. When moving the discharge plate 6, the discharge plate 6 moves more smoothly through the pulley.

[0034] Finally, see Figure 1 The drying device 2 is fixedly installed on one side of the injection molding machine body 1. A fixing ring is sleeved on the outer side of the drying device 2. A support rod is connected between one side of the fixing ring and the injection molding machine body 1. The drying device 2 is stably connected to the injection molding machine body through the fixing ring and the support column to prevent the drying device 2 from tilting due to excessive weight of the internal raw materials.

[0035] In addition, it should be supplemented according to the above embodiments that the injection molding machine body 1, the motor 2012, the heat dissipation fan and the hot air blower 4 are all existing technologies, and their internal working principles and operating procedures will not be described in detail here.

[0036] The working process of the utility model is as follows: when using the injection molding machine, the user first turns on the hot air blower 4 to preheat the inside of the feed bin 201, then pulls the discharge plate 6 by the handle, and after pulling it open, the user rotates the discharge plate 6 to make the slide 602 close to the side of the feed bin 201 for simple storage, and then pours the raw materials into the feed bin 201, and then turns on the motor 2012 to rotate the first rotating wheel. At the same time, the first rotating wheel causes the second rotating wheel to rotate synchronously through the conveyor belt. When the second rotating wheel rotates, the stirring rod 5 is driven to rotate at the same time, and the hot air enters the inside of the feed bin 201 through the internal transmission of the stirring rod 5. As the stirring rod 5 rotates, the hot air evenly dries the raw materials inside the feed bin 201. While drying, the user turns on the heat dissipation fan to cool down the internal temperature. During injection molding, the user rotates the screw rod 3 to make the square plate 2011 enter and exit the empty slot, control the raw materials to be transported into the injection molding machine body 1 through the discharge funnel 202 for melting, and quantitatively transport the raw materials. When the raw materials are not needed, the screw rod 3 is rotated to close the square plate 2011.

[0037] The entire operation process is simple and convenient. Compared with the existing injection molding machines, the utility model can evenly dry the raw materials through the design of the square plate and the stirring rod, and directly put the raw materials into the injection molding machine for melting according to the demand.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
