Description

Technical Field

[0001] This invention relates to the field of injection molding machine technology, specifically to an injection molding machine with an anti-clogging material conveying structure. Background Technology

[0002] In traditional injection molding processes, there are numerous problems with raw material handling and conveying. On one hand, plastic raw materials often contain fine impurities and agglomerated material. These impurities severely affect the physical properties and appearance of the product during injection molding, while agglomerated material cannot fully fill the mold cavity, affecting the product's density and quality stability. On the other hand, moisture in the raw material easily causes defects such as bubbles and cracks due to evaporation during injection molding. Furthermore, unheated raw materials have poor flowability, requiring higher injection pressure and temperature, which not only increases energy consumption but also prolongs the injection cycle and reduces production efficiency. Uneven cooling and solidification can increase internal stress in the product, making it difficult to guarantee dimensional accuracy. In addition, traditional feeding methods are inefficient, making it difficult to accurately control the feeding amount and time according to production needs. The raw material conveying speed cannot be flexibly adjusted, easily leading to unstable raw material supply and affecting the quality of injection molded products. Moreover, the entire production process has low automation, requires significant manual intervention, is labor-intensive, and suffers from poor production accuracy and consistency, making it difficult to meet the demands of large-scale, high-efficiency production. Summary of the Invention

[0003] The purpose of this invention is to provide an injection molding machine with an anti-clogging material conveying structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an injection molding machine with an anti-blocking raw material conveying structure, comprising a machine body, a feeding assembly disposed on the top of the machine body, and a pretreatment assembly disposed on the side of the machine body. The pretreatment assembly includes a support, a separating cylinder fixed above the support, a discharge hopper fixed below the separating cylinder, an opening and closing door disposed above the separating cylinder, a connecting cylinder one connected to one end of the separating cylinder, a connecting cylinder two fixed to the other end of the separating cylinder, a screening cylinder rotatably disposed inside the connecting cylinder two, the two ends of the screening cylinder being connected to the connecting cylinder one and the connecting cylinder two respectively, a rotating shaft rotatably disposed inside the connecting cylinder one and the connecting cylinder two, a sleeve shaft fixed on the rotating shaft, and several fixing rods fixed on the sleeve shaft, all of which are fixed inside the screening cylinder.

[0005] Two support legs are fixed at the bottom of the machine body, a clamping assembly is provided at the top of the machine body, a feeding hopper is provided inside the machine body, a feeding pipe is fixed below the feeding hopper, a conveying pipe is provided below the feeding pipe, a conveying auger is rotatably provided inside the conveying pipe, a conveying motor is fixed inside the machine body, and a pulley pair is provided between the output shaft of the conveying motor and the end of the conveying auger.

[0006] With the above structure, the machine body serves as the main frame of the entire machine, and is stably supported by two support legs. Inside the machine body, there is a feed hopper 1 for receiving pre-treated plastic raw materials. The raw materials enter the feed pipe 2 below from the feed hopper 1, and then fall into the horizontally arranged conveying pipe. The conveying pipe is equipped with a conveying auger, which is driven by a conveying motor fixed inside the machine body. The output shaft of the conveying motor is connected to the end of the conveying auger through a pulley pair 1 to realize power transmission, causing the conveying auger to rotate and thus pushing the material forward to the injection molding unit. At the same time, a clamping assembly is provided on the top of the machine body for automatically removing the molded products, realizing automated production. The setting of the conveying auger can realize stable and continuous conveying of raw materials. Through the drive of the conveying motor and the pulley pair 1, the rotation speed of the conveying auger can be precisely controlled, thereby adjusting the conveying speed of raw materials according to production needs, ensuring a stable supply of raw materials during the injection molding process, and avoiding the impact of insufficient or excessive raw material supply on the quality of injection molded products.

[0007] The pretreatment component also includes a mounting box, which is fixed to the end of the connecting cylinder two. A drive motor is fixed to the side of the mounting box. A pulley pair two is connected to one end of the output shaft of the drive motor and the rotating shaft. A push auger is fixed to one end of the rotating shaft. The push auger is located inside the connecting cylinder two. A feed hopper two is fixed above the connecting cylinder two.

[0008] Using the above structure, the pretreatment component is supported by a bracket, and the separation cylinder is fixed above the bracket. The raw material enters from the feed hopper two above the connecting cylinder two. The drive motor starts and drives the rotating shaft to rotate through the pulley pair two. The sleeve shaft on the rotating shaft rotates accordingly, which in turn drives the fixed rod fixed on the sleeve shaft to rotate. Since the fixed rod is fixed inside the screening cylinder, the screening cylinder will also rotate. After the raw material enters the screening cylinder, it is screened during the rotation of the screening cylinder. The raw material that meets the particle size requirements enters the connecting cylinder one through the screening cylinder, and then enters the storage tank through the slide pipe. Raw materials that do not meet the particle size requirements remain in the screening cylinder. A pusher auger fixed at one end of the rotating shaft is located inside the connecting cylinder two, which helps to push the raw materials towards the screening cylinder, ensuring that the raw materials smoothly enter the screening cylinder for screening. Through the rotation of the screening cylinder, raw materials that meet the particle size requirements can be effectively separated, improving the quality of the raw materials and providing higher quality raw materials for the subsequent injection molding process, ensuring the quality stability of the injection molded products. At the same time, the pusher auger helps the raw materials to smoothly enter the screening cylinder, avoiding blockage of the raw materials in the connecting cylinder two, and improving the smoothness of the raw material conveying.

[0009] A control box is fixed above the support, a base is provided on the side of the support, a storage tank is fixed above the base, a sliding pipe is connected to the bottom of the connecting cylinder, the sliding pipe is connected to the connecting cylinder, a cover plate is fixed above the storage tank, a guide block is fixed inside the storage tank, a hot air blower is fixed above the cover plate, the air outlet of the hot air blower is rotatably connected to the other end of the rotating shaft, an inner hole is opened inside the rotating shaft, and several air inlets are opened on the rotating shaft and the connecting shaft, all of which are connected to the inner hole.

[0010] Using the above structure, the pre-treated raw material enters the storage tank through the drop pipe. The guide blocks inside the storage tank guide the raw material, ensuring its proper distribution. When the hot air blower is activated, hot air enters the inner hole of the rotating shaft from the outlet end and is then blown out through several air inlets on the rotating shaft and the connecting shaft, drying the raw material in the storage tank. During the rotation of the rotating shaft, the hot air can act more evenly on the raw material, improving the drying effect. The guide blocks ensure that the raw material is evenly distributed in the storage tank, preventing excessive accumulation in certain areas. The hot air blower, through the rotating shaft and air inlets, effectively removes moisture from the raw material, preventing problems such as clumping and blockage due to excessive moisture content during subsequent conveying and injection molding, thus ensuring smooth material conveying and injection molding quality.

[0011] The feeding assembly includes a fixing plate, which is fixed above the machine body. A discharge pipe is fixed above the fixing plate, a control valve is installed above the discharge pipe, a receiving tank is fixed above the control valve, a vacuum pump is installed above the receiving tank, a feed pipe is connected to the side of the receiving tank, and the end of the feed pipe extends through into the interior of the storage tank. A control box is installed on the side of the discharge pipe.

[0012] With the above structure, the vacuum pump starts, creating negative pressure inside the receiving tank. Under this negative pressure, the raw materials in the storage tank are drawn into the receiving tank through the feed pipe 1. The control valve controls the outflow of raw materials from the receiving tank. When raw materials need to be fed into the machine, the control valve is opened, and the raw materials enter the feed hopper 1 inside the machine through the discharge pipe from the receiving tank. The control box 2 can control and monitor the feeding process. Using a vacuum pump to create negative pressure for feeding enables rapid and efficient conveying of raw materials, improving feeding efficiency. The control valve and control box 2 make the feeding process more controllable, allowing for accurate control of the feeding quantity and time according to production needs, ensuring the continuity and stability of production.

[0013] Compared with the prior art, the beneficial effects of the present invention are: An injection molding machine with an anti-clogging raw material conveying structure effectively removes excessively fine particles from the raw material and breaks up agglomerated materials by rotating the screening cylinder of the pretreatment component and stirring with a fixed rod, thus improving the quality of the raw material. A hot air blower is used to dry and preheat the raw material through a rotating shaft and air inlet, removing moisture, improving the material's flowability, reducing injection molding pressure and temperature, decreasing energy consumption and product defects, and improving dimensional accuracy. A vacuum pump is used for negative pressure feeding, with precise control via a control box and control valves, achieving rapid and efficient feeding. The conveyor auger precisely controls its speed for stable material delivery. The entire process is highly automated, with automatic component clamping and removal, reducing manual intervention, improving production accuracy and consistency, and facilitating large-scale, high-efficiency production.

[0018] Two support legs 19 are fixed to the bottom of the machine body 5. A clamping assembly 12 is installed on the top of the machine body 5. A feeding hopper 13 is installed inside the machine body 5. A feeding pipe 25 is fixed below the feeding hopper 13. A conveying pipe 20 is installed below the feeding pipe 25. A conveying auger 16 is rotatably installed inside the conveying pipe 20. A conveying motor 18 is fixed inside the machine body 5. A pulley pair 17 is installed between the output shaft of the conveying motor 18 and the end of the conveying auger 16. The machine body 5 serves as the main frame of the entire machine. It is stably supported by the two support legs 19. The feeding hopper 13 inside the machine body 5 is used to receive pre-treated plastic raw materials. The raw materials enter the feeding pipe 25 below from the feeding hopper 13 and then fall into the horizontally arranged conveying pipe 2. In the injection molding unit 0, a conveying auger 16 is installed inside the conveying pipe 20, driven by a conveying motor 18 fixed inside the machine body 5. The output shaft of the conveying motor 18 is connected to the end of the conveying auger 16 through a pulley pair 17 to achieve power transmission, causing the conveying auger 16 to rotate and push the material forward to the injection molding unit. At the same time, a clamping assembly 12 is provided above the machine body 5 for automatically removing the molded products, realizing automated production. The setting of the conveying auger 16 can achieve stable and continuous conveying of raw materials. Through the drive of the conveying motor 18 and the pulley pair 17, the rotation speed of the conveying auger 16 can be precisely controlled, thereby adjusting the conveying speed of raw materials according to production needs, ensuring a stable supply of raw materials during the injection molding process, and avoiding the impact of insufficient or excessive supply of raw materials on the quality of injection molded products.

[0019] The pretreatment assembly also includes a mounting box 34, which is fixed to the end of the connecting cylinder 30. A drive motor 7 is fixed to the side of the mounting box 34. The output shaft of the drive motor 7 is connected to a pulley pair 29 at one end of the rotating shaft 32. A pusher auger 39 is fixed to one end of the rotating shaft 32 and is located inside the connecting cylinder 30. A feed hopper 31 is fixed above the connecting cylinder 30. The pretreatment assembly is supported by a bracket 26. The separating cylinder 21 is fixed above the bracket 26. The raw material enters from the feed hopper 31 above the connecting cylinder 30. The drive motor 7 starts and drives the rotating shaft 32 to rotate through the pulley pair 29. The sleeve shaft 28 on the rotating shaft 32 rotates accordingly, which in turn drives the fixed rod 14 fixed on the sleeve shaft 28 to rotate. Since the fixed rod 14 is fixed to the screening... The screening cylinder rotates inside the drum. After the raw material enters the screening cylinder, it is screened during the rotation of the screening cylinder. The raw material that meets the particle size requirements enters the connecting cylinder 22 through the screening cylinder and then enters the storage tank 9 through the slide pipe 23. The raw material that does not meet the particle size requirements remains in the screening cylinder. The push auger 39, which is fixed at one end of the rotating shaft 32, is located inside the connecting cylinder 30. It can help push the raw material towards the screening cylinder to ensure that the raw material enters the screening cylinder smoothly for screening. Through the rotation of the screening cylinder, the raw material that meets the particle size requirements can be effectively separated, improving the quality of the raw material and providing better raw material for the subsequent injection molding process, ensuring the quality stability of the injection molded product. At the same time, the setting of the push auger 39 helps the raw material to enter the screening cylinder smoothly, avoids the raw material from being blocked in the connecting cylinder 30, and improves the smoothness of the raw material conveying.

[0020] A control box 6 is fixed above the support 26. A base 25 is provided on the side of the support 26. A storage tank 9 is fixed above the base 25. A sliding pipe 23 is connected to the bottom of the connecting cylinder 22 and is connected to the connecting cylinder 22. A cover plate 24 is fixed above the storage tank 9. A guide block 33 is fixed inside the storage tank 9. A hot air blower 10 is fixed above the cover plate 24. The air outlet of the hot air blower 10 is rotatably connected to the other end of the rotating shaft 32. An inner hole 36 is opened inside the rotating shaft 32. Several air inlets 37 are opened on the rotating shaft 32 and the sleeve shaft 28. The air inlets 37 are all connected to the inner hole 36. The pre-treated raw material enters the storage tank 9 through the sliding pipe 23. The guide block 33 inside the storage tank 9 guides the raw material. The guide block 33 guides the material to be distributed reasonably within the storage tank 9. When the hot air blower 10 is started, hot air enters the inner hole 36 of the rotating shaft 32 from the air outlet and is then blown out through several air inlets 37 on the rotating shaft 32 and the sleeve shaft 28 to dry the material in the storage tank 9. During the rotation of the rotating shaft 32, the hot air can act more evenly on the material, improving the drying effect. The guide block 33 ensures that the material is evenly distributed within the storage tank 9, avoiding excessive accumulation of material in certain areas. The hot air blower 10 dries the material through the rotating shaft 32 and the air inlets 37, effectively removing moisture from the material and preventing problems such as clumping and blockage due to excessive moisture content during subsequent conveying and injection molding, thus ensuring smooth material conveying and injection molding quality.

[0021] The feeding assembly includes a fixing plate 4, which is fixed above the machine body 5. A discharge pipe 3 is fixed above the fixing plate 4, and a control valve 35 is installed above the discharge pipe 3. A receiving tank 2 is fixed above the control valve 35, and a vacuum pump 1 is installed above the receiving tank 2. A feed pipe 11 is connected to the side of the receiving tank 2, and the end of the feed pipe 11 extends into the interior of the storage tank 9. A control box 38 is installed on the side of the discharge pipe 3. When the vacuum pump 1 is activated, a negative pressure is created inside the receiving tank 2. Under this negative pressure, the raw material in the storage tank 9 is drawn into the receiving tank through the feed pipe 11. Tank 2 and control valve 35 can control the outflow of raw materials in receiving tank 2. When it is necessary to transport raw materials into machine body 5, control valve 35 is opened, and raw materials enter the feed hopper 13 in machine body 5 from receiving tank 2 through discharge pipe 3. Control box 2 38 can control and monitor the feeding process. The negative pressure feeding method formed by vacuum pump 1 can realize the rapid and efficient transportation of raw materials and improve feeding efficiency. The setting of control valve 35 and control box 2 38 makes the feeding process more controllable. The feeding amount and feeding time can be accurately controlled according to production needs to ensure the continuity and stability of production.

[0022] Working principle: Plastic raw materials enter the pretreatment assembly from the feed hopper 31 above the connecting cylinder 30. The drive motor 7 starts, driving the rotating shaft 32 to rotate via the pulley pair 29. The sleeve shaft 28 on the rotating shaft 32 rotates accordingly, which in turn drives the fixed rod 14 fixed to the sleeve shaft 28 to rotate. Since the fixed rod 14 is fixed inside the screening cylinder, the screening cylinder also rotates. After the raw material enters the screening cylinder, during the rotation, excessively fine materials will pass through the screen holes of the screening cylinder and be separated, achieving the screening purpose. Simultaneously, the rotation of the screening cylinder and the stirring action of the fixed rod 14... The rotating shaft 32 is equipped with a pusher auger 39 fixed at one end, located inside the connecting cylinder 2 30. This auger assists in pushing the raw material towards the screening cylinder, ensuring that the raw material smoothly enters the screening cylinder for screening and dispersing. After screening and dispersing, the raw material enters the storage tank 9 through the slide pipe 23. The guide block 33 inside the storage tank 9 guides the raw material, ensuring that it is reasonably distributed within the storage tank 9. The hot air blower 10 is started, and hot air enters the inner hole 36 of the rotating shaft 32 from the outlet end, and then passes through several feeders on the rotating shaft 32 and the connecting shaft 28. Air is blown out through vent 37 to dry the raw materials in storage tank 9. During the drying process, hot air preheats the raw materials simultaneously. As the rotating shaft 32 rotates, the hot air can act more evenly on the raw materials, improving the drying and preheating effects. The guide block 33 is designed to prevent excessive accumulation of raw materials in certain areas, ensuring that all raw materials can fully receive the hot air. Vacuum pump 1 is started, creating negative pressure in receiving tank 2. The raw materials in storage tank 9, after being screened, dispersed, dried, and preheated, are drawn into receiving tank 2 through feed pipe 11 under negative pressure. Control box 38 can control the feeding. The process is controlled and monitored. The vacuum pump 1 is started and stopped according to production needs. When raw materials need to be fed into the machine body 5, the control valve 35 above the discharge pipe 3 is opened. The raw materials enter the feed hopper 13 inside the machine body 5 from the receiving tank 2 through the discharge pipe 3. The raw materials entering the feed hopper 13 inside the machine body 5 fall into the conveying pipe 20 through the feed pipe 2 15. The conveying motor 18 is started and drives the conveying auger 16 to rotate through the pulley pair 17, pushing the raw materials forward to the injection molding unit. At the same time, the clamping component 12 above the machine body 5 automatically takes out the molded products, realizing automated production. The rotating sieving cylinder effectively removes excessively fine particles from the raw materials, preventing these particles from affecting the physical properties and appearance of the product during injection molding. Simultaneously, the sieving and stirring action of the fixing rod 14 breaks up any clumps of raw materials, resulting in uniform particle size and good dispersion. This facilitates full filling of the mold cavity during injection molding, improving product density and quality stability. The hot air blower 10 dries and preheats the raw materials, removing moisture and preventing defects such as bubbles and cracks caused by excessive moisture evaporation during injection molding. Preheated raw materials have better flowability when entering the injection molding unit, reducing injection pressure and temperature, decreasing energy consumption, shortening the injection cycle, and improving production efficiency. Furthermore, uniform preheating allows for more even cooling and solidification of the raw materials within the mold, reducing internal stress and improving overall product quality. To ensure the dimensional accuracy and stability of the product, a vacuum pump 1 is used to create negative pressure for feeding, enabling rapid and efficient material transport. Compared to traditional feeding methods, this shortens feeding time and improves feeding efficiency. The control box 2 38 and control valve 35 make the feeding process more controllable, allowing for precise control of the feeding quantity and time according to production needs, ensuring production continuity and stability. The conveying auger 16 is driven by the conveying motor 18 and pulley pair 17, allowing for precise speed control. This adjusts the material conveying speed according to production needs, ensuring a stable material supply during the injection molding process and preventing insufficient or excessive material supply from affecting the quality of the injection molded product. From material pretreatment and feeding to conveying and injection molding, each step is automated. The clamping component 12 can automatically remove the molded product, reducing manual intervention and labor intensity, which is conducive to large-scale, high-efficiency production.
