Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1 to 5 , the present utility model provides a technical solution:

[0026] An injection molding device for producing plastic barrels, including an outer shell 1, two support legs 2 are fixedly installed at the lower end of the outer surface of the outer shell 1, a feed pipe 3 is communicated with the left end surface of the outer shell 1, a discharge pipe 4 is communicated with the right end surface of the outer shell 1, a motor 5 is fixedly installed at the right end of the outer shell 1, an ash collection hose 6 is fixedly installed at the right end of the outer shell 1, an air outlet 7 is opened on the right end surface of the outer shell 1 for the ash collection hose 6, a quantitative screening and mixing mechanism is arranged inside the outer shell 1, a preheating and ash removal mechanism is arranged on the left side of the outer shell 1, the quantitative screening and mixing mechanism includes a rotating shaft 10 rotatably connected inside the outer shell 1, a screening cylinder 8 is sleeved on the outer surface of the rotating shaft 10, the screening cylinder 8 is rotatably connected with the outer shell 1, a fixing rod is fixedly installed between the right end surface of the screening cylinder 8 and the rotating shaft 10, and a screw auger 9 is fixedly installed on the outer surface of the screening cylinder 8.

[0027] During the feeding process of existing plastic particles, it is inconvenient to control the uniform feeding and it is inconvenient to separate the impurities in the plastic particles, which leads to poor practicality. Therefore, the utility model sets a quantitative screening and mixing mechanism. First, different types of plastic particles are mixed. During the mixing process, the impurities in the plastic particles will be screened and removed, and the qualified plastic particles will be quantitatively transported to avoid the staged rushing in of a large number of plastic particles, which will affect the melting rate of the plastic particles and further affect the production efficiency of the equipment.

[0028] The discharge pipe 4 is interconnected with the plastic particle melting equipment, and the melted plastic particles can be injection molded. At the same time, the dust collecting hose 6 is interconnected with the external dust removal equipment, which can store the dust and impurities discharged by the equipment to prevent the dust from floating into the atmosphere and polluting the air. First, the plastic particles enter the interior of the screening cylinder 8 in the outer shell 1 through the feed pipe 3, and then the motor 5 is started to make the output shaft of the motor 5 drive the rotating shaft 10 to rotate, and the rotating shaft 10 carries the screening cylinder 8 to rotate through the fixed rod. The rotating shaft 10 also carries the stirring rod 11 to rotate, and different plastic particles are mixed. At the same time, the large impurities in the plastic particles will be intercepted by the screening cylinder 8, and the plastic particles are discharged into the spiral auger 9. As the spiral auger 9 rotates, it gradually enters the plastic melting equipment from the discharge pipe 4. The equipment of the spiral auger 9 can quantitatively process the plastic particles. Secondly, a discharge valve is provided at the right end of the outer shell 1 corresponding to the screening cylinder 8, and the equipment is inclined. Under the influence of gravity, the discharge valve is opened to discharge the intercepted impurities from the equipment.

[0029] The preheating and dust removal mechanism comprises a cam 12 arranged on the left side of the housing 1 , and one end of the rotating shaft 10 extends to the left side of the housing 1 and is fixedly connected to the cam 12 .

[0030] A sleeve 13 is provided on the lower side of the cam 12, and a piston plate 17 is fixedly installed between the sleeve 13 and the outer shell 1. A transmission column 16 is fixedly installed on the upper end of the piston plate 17. A force plate 15 is provided on the upper side of the sleeve 13, and one end of the transmission column 16 extends to the upper side of the sleeve 13 and is fixedly connected to the force plate 15.

[0031] The force-bearing plate 15 is arranged at the lower side of the cam 12 . A spring 18 is fixedly installed between the force-bearing plate 15 and the sleeve 13 . The spring 18 is sleeved on the outer surface of the transmission column 16 .

[0032] A heating tube 19 is provided at the lower side of the sleeve 13 , and a heating wire is fixedly installed inside the heating tube 19 . An air intake pipe 20 is connected between the sleeve 13 and the heating tube 19 , and a one-way air intake valve is provided inside the air intake pipe 20 .

[0033] The lower end face of the sleeve 13 is communicated with an air outlet pipe 21. Inner cavities 22 are formed inside the rotating shaft 10 and the stirring rod 11, and the air outlet pipe 21 is communicated with the inner cavities 22.

[0034] The air outlet pipe 21 is rotatably connected to the cam 12. A plurality of groups of air injection holes 23 are formed on the outer surface of the stirring rod 11, and the air injection holes 23 are communicated with the inner cavities 22.

[0035] A large amount of energy is consumed during the melting stage of plastic particles. The melting speed of plastic particles also has a crucial impact on the production efficiency of injection molding equipment. Therefore, the present utility model sets up a preheating and dust removal mechanism. By injecting hot air into the plastic particles during the stirring stage, the plastic particles are preheated to accelerate the melting rate of the plastic particles. At the same time, the hot air blown out can also blow away the fine dust and impurities in the plastic particles and discharge them from the equipment, further improving the quality of the plastic particles.

[0036] Secondly, when the rotating shaft 10 rotates, it will drive the cam 12 to rotate. When the cam 12 rotates to the lower side, it will squeeze the force-bearing plate 15 on the transmission column 16, causing the piston plate 17 to descend. When the cam 12 rotates to the upper side, the force-bearing plate 15 will move upward to restore its original position under the action of the spring 18. At the same time, the piston plate 17 is carried upward by the transmission column 16. In this way, as the cam 12 rotates continuously, the piston plate 17 can be driven to reciprocate inside the sleeve 13. When the piston plate 17 moves upward, it will open the one-way intake valve in the intake pipe 20 and draw the hot air heated by the heating wire in the heating pipe 19 into the inside of the sleeve 13. When the piston plate 17 moves downward, it will discharge the hot air inside the sleeve 13 into the inner cavity 22 by opening the one-way outlet valve in the air outlet pipe 21, and finally spray out from the air injection holes 23 to preheat the plastic particles being mixed. At the same time, while raising the plastic particles, the dust in the plastic particles can be blown towards the air outlet 7 and discharged to the external storage device through the dust collection hose 6.

[0037] Working principle: The discharge pipe 4 is interconnected with the plastic particle melting equipment. After the plastic particles are melted, they can be injection-molded. At the same time, the dust collection hose 6 is interconnected with an external dust removal device, which can store the dust and impurities discharged by the equipment, preventing the dust from floating into the atmosphere and polluting the air. First, the plastic particles enter the inside of the screening cylinder 8 in the housing 1 through the feed pipe 3. Then, the motor 5 is started, and the output shaft of the motor 5 drives the rotating shaft 10 to rotate. The rotating shaft 10 drives the screening cylinder 8 to rotate through the fixing rod. The rotating shaft 10 also drives the stirring rod 11 to rotate to mix different plastic particles. At the same time, the large impurities in the plastic particles are intercepted by the screening cylinder 8, and the plastic particles are discharged into the spiral auger 9. As the spiral auger 9 rotates, the plastic particles gradually enter the plastic melting equipment through the discharge pipe 4. The spiral auger 9 can quantitatively process the plastic particles. Secondly, a discharge valve is provided at the right end of the housing 1 corresponding to the screening cylinder 8, and the equipment is inclined. Under the influence of gravity, when the discharge valve is opened, the intercepted impurities can be discharged from the equipment;

[0038] Secondly, when the rotating shaft 10 rotates, it drives the cam 12 to rotate. When the cam 12 rotates to the lower side, it presses the force-bearing plate 15 on the transmission column 16, causing the piston plate 17 to descend. When the cam 12 rotates to the upper side, the force-bearing plate 15 moves upward to restore its original position under the action of the spring 18, and at the same time drives the piston plate 17 to move upward through the transmission column 16. Thus, as the cam 12 rotates continuously, the piston plate 17 can be driven to reciprocate inside the sleeve 13. When the piston plate 17 moves upward, it opens the one-way intake valve in the intake pipe 20 and draws the hot air heated by the heating wire in the heating pipe 19 into the inside of the sleeve 13. When the piston plate 17 moves downward, it discharges the hot air inside the sleeve 13 through the one-way outlet valve opened in the outlet pipe 21 into the inner cavity 22, and finally sprays out from the air spray hole 23 to preheat the plastic particles being mixed. At the same time, while raising the plastic particles, it can also blow the dust in the plastic particles towards the air outlet 7 and discharge it to an external storage device through the dust collection hose 6.

[0039] Finally, it should be noted that: The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it; Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: They can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; And these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
