[0036] See also Figures 1 to 5 The present invention provides a high-efficiency injection molding machine, and the technical solution is as follows:

[0037] A high-efficiency injection molding machine, comprising:

[0038] A frame 1, wherein an injection molding unit 2 is arranged in the frame 1;

[0039] A hopper 3, which is fixedly connected to the top of the frame 1;

[0040] Also includes:

[0041] A suction unit 4, which is arranged above the hopper 3;

[0042] A raw material barrel 5, which is arranged on one side of the frame 1 and fixed on the frame 1. A raw material barrel cover 504 is fixedly connected to the top of the raw material barrel 5, and a sealing ring is provided at the connection between the raw material barrel 5 and the raw material barrel cover 504;

[0043] A feed pipe 6, one end of which is fixedly connected to the top of the suction unit 4, and the other end of which extends into the raw material barrel 5 through the raw material barrel cover 504, and a sealing ring is provided at the connection between the feed pipe 6 and the raw material barrel cover 504;

[0044] The material suction control unit 7 is arranged outside the material suction unit 4 .

[0045] The hopper 3 is used to feed the injection unit 2. The raw material barrel cover 504 can be opened to add raw materials into the raw material barrel 5. The suction unit 4 is used to suck the raw materials in the raw material barrel 5 into the hopper 3 through the feeding pipe 6 to realize automatic feeding. The sealing ring can avoid air leakage during the suction process.

[0046] As an embodiment of the present invention, refer to Figure 1-2 The raw material barrel 5 is inverted, and the output end of the raw material barrel 5 is downwardly connected to one end of the feed pipe 6. A counterweight plate 501 is provided in the raw material barrel 5, and the counterweight plate 501 is slidably connected in the raw material barrel 5.

[0047] The inverted raw material barrel 5 can facilitate the suction unit 4 to suck the material. The counterweight plate 501 applies downward pressure to the raw material in the raw material barrel 5, so that the raw material is pressed more tightly, allowing the suction unit 4 to suck the raw material into the hopper 3 more conveniently.

[0048] As an embodiment of the present invention, refer to Figure 1-2 The feed pipe 6 is made of a flexible material and has a certain degree of ductility. A layer of elastic steel wire 601 is arranged inside the wall of the feed pipe 6 .

[0049] The feed pipe 6 is made of flexible material, which can cope with many terrain restrictions and facilitate the installation of the equipment. The elastic steel wire 601 in the feed pipe 6 can reduce the tangling of the feed pipe 6 during the transportation of the equipment, and can also reduce the impact and friction on the feed pipe 6 when the suction force of the suction unit 4 is too large.

[0050] As an embodiment of the present invention, refer to Figure 1-2 A rotating motor 301 is fixedly installed above the inside of the hopper 3, and a closed door 302 is provided at the connection between the hopper 3 and the suction unit 4. The closed door 302 is rotatably arranged on the inner side of the hopper 3, and a connecting rod 303 is fixedly connected to one side of the closed door 302. The end of the connecting rod 303 away from the closed door 302 is fixedly connected to the output end of the rotating motor 301.

[0051] The closed door 302 is in a normally closed state to prevent the suction unit 4 from sucking in the raw materials in the hopper 3 when sucking the materials. When the materials in the hopper 3 are used up, the suction unit 4 is started and the raw materials will be accumulated in the suction unit 4. When too much raw materials are accumulated, the closed door 302 will be controlled to open, so that the raw materials accumulated in the suction unit 4 can enter the hopper 3.

[0052] As an embodiment of the present invention, refer to Figure 1-4 The suction unit 4 includes an exhaust fan 401 , and the exhaust fan 401 is rotatably connected to the inner wall of the suction unit 4 .

[0053] The exhaust fan 401 is usually in a closed state. When the hopper 3 needs to absorb raw materials, the exhaust fan 401 is turned on to suck the raw materials in the raw material barrel 5 to the side of the exhaust fan 401. When too much raw material is accumulated in the suction unit 4, the closed door 302 will be controlled to open, and the raw materials accumulated in the suction unit 4 will fall into the hopper 3 by gravity, completing the suction operation.

[0054] As an embodiment of the present invention, refer to Figure 2-4 A material blocking net 402 is provided on the air suction side of the exhaust fan 401 , and the material blocking net 402 is fixedly connected to the inner wall of the suction unit 4 .

[0055] During the process of the exhaust fan 401 sucking materials, the raw materials may enter the exhaust fan 401 and damage the exhaust fan 401. The material blocking net 402 can reduce the raw materials from entering the exhaust fan 401 as much as possible, thus playing a role of safety protection and improving the service life of the equipment.

[0056] As an embodiment of the present invention, refer to Figure 2-3 A start button 304 is provided at the bottom of the inner wall of the hopper 3 , and the start button 304 is fixedly connected to the inner wall of the hopper 3 .

[0057] The accumulation of raw materials in the hopper 3 presses the start button 304, and the suction unit 4 is in a closed state. When the raw materials in the hopper 3 are consumed and the start button 304 is released, the suction unit 4 is started, and the exhaust fan 401 starts to work, sucking the raw materials in the raw material barrel 5 into the suction unit 4 to replenish the raw materials. When the raw materials accumulate too much in the suction unit 4, the closed door 302 will be controlled to open, and the raw materials accumulated in the suction unit 4 will fall into the hopper 3 by gravity, completing the suction operation.

[0058] As an embodiment of the present invention, refer to Figure 2-3 A feeding alarm button 502 is fixedly arranged at the bottom of the raw material barrel 5, and an alarm light 503 is fixedly connected to the outer wall of the hopper 3.

[0059] When there are raw materials in the raw material barrel 5, the raw material will press the feeding alarm button 502, and the alarm light 503 will be off. When the raw materials in the raw material barrel 5 are consumed, the feeding alarm button 502 will be released, triggering the alarm light 503 to alarm, reminding outsiders that they need to add raw materials.

[0060] As an embodiment of the present invention, refer to Figure 1-4 The suction control unit 7 includes a trigger rod 701, which is rotatably connected to the inner wall of the suction control unit 7. The trigger rod 701 is located at the air outlet end of the exhaust fan 401. The end of the trigger rod 701 away from the inner wall of the suction control unit 7 is provided with a protrusion toward the exhaust fan 401. An electric telescopic rod 702 is provided between the trigger rod 701 and the exhaust fan 401. The electric telescopic rod 702 is fixedly connected to the inner wall of the suction control unit 7. A control button 703 is fixedly connected to the output end of the electric telescopic rod 702. The trigger end of the control button 703 faces the protrusion of the trigger rod 701. An elastic rope 704 is fixedly connected between the electronic trigger rod 701 and the trigger rod 701.

[0061] When the exhaust fan 401 is working, the trigger rod 701 is rotated and offset away from the exhaust fan 401 under the action of the wind force of the exhaust fan 401. When the start button 304 is started, the electric telescopic rod 702 is started, and the control button 703 is pushed to the original position of the protrusion of the trigger rod 701. When a lot of raw materials are sucked onto the material blocking net 402 and cause the material blocking net to be blocked, the wind sucked by the exhaust fan 401 is not enough to make the trigger rod 701 rotate and offset away from the exhaust fan 401. The trigger rod 701 returns and triggers the control button 703 under the action of gravity and the elastic rope 704. The exhaust fan 401 will stop rotating and open the closed door 302 at the same time, so that the raw materials in the suction unit 4 fall into the hopper 3. The delay control opening time of the closed door 302 can be set to complete the suction operation. When the raw materials in the hopper 3 are accumulated, the start button 304 will be pressed again, and the electric telescopic rod 702 will return to complete a control cycle.

[0062] As an embodiment of the present invention, refer to Figure 1-5 A warning light tube 705 is arranged above the material suction control unit 7, and the light tube is fixedly connected to the top of the material suction control unit 7. An exhaust port 706 is installed on one side of the material suction control unit 7. A dust suction net support plate 707 is installed in the exhaust port 706. The bottom end of the dust suction net support plate 707 is elastically connected to the inside of the material suction control unit 7. A dust suction net 708 is fixedly installed on the top of the dust suction net support plate 707. A light tube alarm button 709 is arranged below the dust suction net support plate 707, and the light tube alarm button 709 is fixedly installed on the inner wall of the material suction control unit 7.

[0063] The exhaust port 706 can allow the air extracted by the exhaust fan 401 to be transmitted to the outside of the equipment, and can also allow the air to enter the equipment when the exhaust fan 401 stops working, so as to balance the air pressure between the equipment and the outside world. When the suction unit 4 is working, it is easy to suck the dust in the raw material into the suction control unit 7, and be adsorbed by the dust suction net 708 at the exhaust port 706. When the dust suction net 708 absorbs too much dust, the weight of the dust suction net 708 will increase, pressing down the dust suction net support plate 707. When the weight is too large and the dust suction net support plate 707 contacts the lamp alarm button 709, the warning lamp 705 will alarm, reminding external personnel that the dust suction net 708 needs to be replaced to avoid congestion in the air path.

[0064] Working principle: raw materials are added between the raw material barrel 5 and the counterweight plate 501. When the raw materials in the hopper 3 are used up, the start button 304 is triggered, and the exhaust fan 401 starts working to suck the raw materials in the raw material barrel 5 into the suction unit 4. The trigger rod 701 is rotated away from the exhaust fan 401 under the action of the wind force of the exhaust fan 401. When the start button 304 is started, the electric telescopic rod 702 is started, and the control button 703 is pushed to the original position of the protrusion of the trigger rod 701. When too much raw materials are piled up in the suction unit 4, the wind force drawn by the exhaust fan 401 decreases, so that the trigger rod 701 returns under the action of gravity and the elastic rope 704 and triggers the control button 703 to open the closed door 302. The delay control opening time of the closed door 302 can be set, and the raw materials on the material baffle plate fall into the hopper 3 under the action of gravity. When the raw materials in the hopper 3 are accumulated, the start button 304 will be pressed again, and the electric telescopic rod 702 will return to complete a control cycle. When the suction unit 4 is working, the dust in the raw materials is easily sucked into the suction control unit 7 and adsorbed by the dust net 708 at the exhaust port 706. When the dust net 708 absorbs too much dust, the weight of the dust net 708 will increase, pressing down the dust net support plate 707. When the weight is too large and the dust net support plate 707 contacts the lamp alarm button 709, the warning lamp 705 will alarm, reminding external personnel to replace the dust net 708 to avoid congestion in the air path. When the raw materials in the raw material barrel 5 are consumed, the feeding alarm button 502 is released, triggering the alarm light 503 to alarm, reminding external personnel to add raw materials.
