Description

Technical Field

[0001] This utility model relates to the field of injection molding machine barrel technology, and in particular to an injection molding machine barrel that facilitates the cleaning of residual material. Background Technology

[0002] With the trend towards lighter and more precise electronic devices, the market demand for computer casings, as core components protecting internal parts and ensuring device stability, continues to grow. Computer casings are typically manufactured using injection molding processes from polymer materials such as ABS and PC / ABS alloys. The injection molding machine barrel, as a key piece of equipment for raw material pretreatment and transport, directly impacts the molding quality (e.g., avoiding defects such as bubbles, material shortages, and uneven textures) and production efficiency of the computer casing. In large-scale computer casing production, a continuous and stable supply of raw materials is required, while simultaneously controlling equipment costs and facilitating subsequent maintenance to meet the demands of high-volume, high-quality production. Therefore, optimizing the performance of the injection molding machine barrel is of great significance to the computer casing production process.

[0003] In existing technologies for injection molding of computer casings, the design of injection molding machine barrels has two significant shortcomings: First, existing injection molding machine barrels have poor coordination between raw material dispersion and conveying. Some barrels only use a single stirring structure to pre-treat the raw materials, and there is no synchronous dispersion mechanism after the raw materials fall to the guide component. The polymer raw materials (such as PC / ABS alloy materials) used in computer casing production are prone to agglomeration due to changes in humidity and pressure during storage or transportation. Agglomerated raw materials can easily clog the opening after entering the guide shroud, leading to interruption of material feeding. Second, the power system design of existing injection molding machine barrels results in high equipment costs. To address this technical problem, this application proposes an injection molding machine barrel that facilitates the cleaning of residual material. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an injection molding machine barrel that facilitates the cleaning of residual materials. The barrel uses a drive shaft to drive gear transmission, which rotates the dispersing shaft to prevent raw material from clumping. Simultaneously, it drives the auger to stabilize material delivery and prevent blockage. Furthermore, through gear linkage, a single motor drives the four major components, reducing the number of power equipment and lowering costs.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An injection molding machine barrel for easy cleaning of residual material includes a barrel body, a barrel cover on one side of the barrel body, a drive shaft rotatably connected to the inner wall of the top of the barrel body, a rotating disk fixedly connected to the bottom end of the drive shaft, a fixed disk fixedly connected to the inner wall of the middle of the barrel body, a stirring shaft rotatably connected to the inner wall of the barrel body, the top end of the stirring shaft being connected to the top end of the drive shaft via a gear set, a support frame fixedly connected to the bottom side of the fixed disk, a dispersing shaft rotatably connected to the bottom side of the support frame, an auger fixedly connected to the bottom end of the dispersing shaft, the bottom side of the drive shaft being connected to the top side of the dispersing shaft via a transmission assembly for controlling the rotation of the dispersing shaft, and a flow guide fixedly connected to the bottom side of the barrel body.

[0006] Furthermore, the gear set includes a second transmission gear fixedly connected to the top side of the transmission shaft, and a first transmission gear fixedly connected to the top side of the stirring shaft. The first transmission gear and the second transmission gear are meshed together.

[0007] Furthermore, the transmission assembly includes a driven gear rotatably connected to the top side of the support frame, a driving gear fixedly connected to the bottom side of the transmission shaft, and transmission gears fixedly connected to the bottom side of the driven gear and the top side of the disintegrating shaft.

[0008] Furthermore, the driving gear and the driven gear are meshed, and the two transmission gears are meshed.

[0009] Furthermore, a protective outer shell is fixedly connected to the top side of the barrel body, and both the first transmission gear and the second transmission gear are disposed inside the protective outer shell.

[0010] Furthermore, a motor is mounted on the top side of the protective housing one via a fixing bracket, and the drive end of the motor is fixedly connected to the top side of the transmission gear two.

[0011] Furthermore, a second protective housing is fixedly connected to the bottom side of the fixed disk, and the support frame and transmission gear are both located inside the second protective housing.

[0012] Furthermore, both the dispersing shaft and the auger are located inside the flow guide shroud, and the outer wall of the material cylinder body is fixedly connected to the feed pipe.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the drive shaft rotates synchronously, driving the drive gear, driven gear, and transmission gear to drive the dispersing shaft to rotate inside the guide shroud. This dispersing effect can break up the falling raw materials and prevent them from clumping. At the same time, the dispersing shaft drives the auger to rotate synchronously, which can stably output the raw materials inside the guide shroud, effectively preventing the raw materials from accumulating and blocking at the opening of the guide shroud, ensuring a continuous and smooth material feeding process, and avoiding the impact of material feeding interruption on injection molding efficiency.

[0014] 2. In this utility model, through the gear linkage mechanism, only a single motor is needed to drive the four functional components: stirring shaft, transmission shaft, dispersing shaft, and auger, which directly reduces the number of power equipment and reduces the cost of the equipment from the source.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 2-4This utility model provides an embodiment of an injection molding machine barrel that facilitates the cleaning of residual material. It includes a barrel body 1, a barrel cover 2 on one side of the barrel body 1, a drive shaft 3 rotatably connected to the inner wall of the top of the barrel body 1, a rotating disk 4 fixedly connected to the bottom end of the drive shaft 3, a fixed disk 5 fixedly connected to the inner wall of the middle section of the barrel body 1, a stirring shaft 6 rotatably connected to the inner wall of the barrel body 1, a second drive gear 12 fixedly connected to the top side of the drive shaft 3, and a first drive gear 11 fixedly connected to the top side of the stirring shaft 6. 1 and transmission gear 12 are meshed. A support frame 16 is fixedly connected to the bottom side of the fixed disk 5. A dispersing shaft 13 is rotatably connected to the bottom side of the support frame 16. An auger 14 is fixedly connected to the bottom end of the dispersing shaft 13. A driven gear 18 is rotatably connected to the top side of the support frame 16. A driving gear 17 is fixedly connected to the bottom side of the transmission shaft 3. A transmission gear 19 is fixedly connected to the bottom side of the driven gear 18 and the top side of the dispersing shaft 13 to control the rotation of the dispersing shaft 13. A flow guide shroud 10 is fixedly connected to the bottom side of the material cylinder body 1. Specifically, firstly, the operator adds injection molding material into the barrel body 1 through the feed pipe 7, completing the initial material feeding. Then, the motor 8, mounted on the top mounting bracket of the protective housing 9, is started. The drive end of the motor 8 directly drives the transmission gear 12, which is fixedly connected to it, to rotate. Since the transmission gear 12 is meshed with the transmission gear 11 fixed on the top side of the stirring shaft 6, the transmission gear 11 rotates accordingly, driving the stirring shaft 6 to rotate on the inner wall of the barrel body 1. Through the rotation of the stirring shaft 6, the injection molding material that has just entered the barrel body 1 is fully premixed, preparing it for subsequent processing. Simultaneously, the transmission gear 12 also drives the transmission gear 12, which is fixedly connected to it... The drive shaft 3 rotates synchronously on the inner wall of the top of the barrel body 1. The rotation of the drive shaft 3 has two effects: First, the rotating disk 4 fixedly connected to the bottom of the drive shaft 3 will rotate accordingly. When the discharge port on the rotating disk 4 coincides with the discharge port on the fixed disk 5 fixedly connected to the inner wall of the middle of the barrel body 1, the pre-mixed raw material will fall down through the coincident discharge port and eventually enter the guide shroud 10 fixedly connected to the bottom side of the barrel body 1, and then enter the subsequent processing stage of the injection molding machine. Second, the drive gear 17 fixedly connected to the bottom side of the drive shaft 3 will rotate with the rotation of the drive shaft 3. Because the drive gear 17 is rotatably connected to the driven gear on the top side of the support frame 16, the drive gear 17 rotates with the drive gear 17. Gears 18 mesh with each other, and the driving gear 17 drives the driven gear 18 to rotate together. The transmission gear 19 fixed to the bottom of the driven gear 18 also rotates accordingly. Since the two transmission gears 19 are meshed, power is transmitted to the dispersing shaft 13 through these two transmission gears 19, causing the dispersing shaft 13 to rotate on the bottom of the support frame 16 and inside the guide shroud 10. This disperses the raw material entering the guide shroud 10, preventing it from clumping. Furthermore, while the dispersing shaft 13 rotates, the auger 14 fixed to its bottom also rotates synchronously. The rotation of the auger 14 can stably output the raw material inside the guide shroud 10, effectively preventing the raw material from piling up at the opening of the guide shroud 10. To prevent blockages and ensure smooth material feeding, thus completing the material conveying and pre-processing work. When the material cylinder is finished and the internal residue needs to be cleaned, since the cylinder cover 2 is connected to the side of the material cylinder body 1, compared to the top of the material cylinder body 1, it is only necessary to open the cylinder cover 2 on one side of the material cylinder body 1 to easily clean the residue inside the material cylinder body 1. A sealing strip is set at the connection between the cylinder cover 2 and the material cylinder body 1 to prevent material leakage when the cylinder cover 2 and the material cylinder body 1 are closed. The drive gear 17 drives the driven gear 18 to rotate together. The transmission ratio between the drive gear 17 and the driven gear 18 realizes the control of the rotation of the dispersing shaft 13 and the auger 14 to output the material.

[0019] Reference Figures 1-3The driving gear 17 and the driven gear 18 are meshed together, and the two transmission gears 19 are meshed together. A protective shell 9 is fixedly connected to the top side of the barrel body 1. Transmission gear 11 and transmission gear 2 12 are both located inside the protective shell 9. A motor 8 is mounted on the top side of the protective shell 9 via a fixing frame. The drive end of the motor 8 is fixedly connected to the top side of the transmission gear 2 12. A protective shell 2 15 is fixedly connected to the bottom side of the fixing plate 5. The support frame 16 and the transmission gear 19 are both located inside the protective shell 2 15. The dispersing shaft 13 and the auger 14 are both located inside the guide shroud 10. A feed pipe 7 is fixedly connected to the outer wall of the barrel body 1. Specifically, the protective outer shell 9 effectively isolates dust, impurities, and raw material particles that may be scattered during the production process from the external environment, preventing these substances from entering the meshing parts of the transmission gear 11 and transmission gear 2 12 contained inside. This prevents the gears from wearing out due to foreign objects getting stuck or contaminating them. At the same time, it provides physical protection for the internal transmission gear 11, transmission gear 2 12, and the connection parts of the drive end of the motor 8, preventing operators from accidentally touching the high-speed rotating gear components during equipment operation and reducing safety hazards. The protective outer shell 2 15 can protect the internal support frame 16 and the two transmission gears 19 from external contamination and damage. During the process of raw materials falling into the guide shroud 10, it can prevent raw material powder or fine particles from adhering to the meshing parts of the transmission gears 19, avoiding obstruction of gear transmission. The motor 8 can be rotated to a suitable power according to actual production needs.

[0020] Working principle: First, raw materials are added into the barrel body 1 through the feed pipe 7. Then, the motor 8 is started. The drive end of the motor 8 drives the transmission gear 12 to rotate. Since the transmission gear 12 meshes with the transmission gear 11, the transmission gear 11 drives the stirring shaft 6 to rotate on the inner wall of the barrel body 1, realizing the premixing of the raw materials entering the barrel body 1. At the same time, the transmission gear 12 drives the transmission shaft 3 to rotate on the inner wall of the top of the barrel body 1. The transmission shaft 3 drives the rotating disk 4 at the bottom to rotate. When the discharge port of the rotating disk 4 and the fixed disk 5 are aligned, the premixed raw materials will fall into the interior of the guide shroud 10 and then enter the interior of the injection molding machine. The transmission shaft 3 also drives the rotating disk 4 at the bottom to rotate. When the discharge port of the rotating disk 4 and the fixed disk 5 are aligned, the premixed raw materials will fall into the interior of the guide shroud 10 and then enter the interior of the injection molding machine. The driving gear 17 on the bottom side rotates, and the driving gear 17 meshes with the driven gear 18 to drive the driven gear 18 to rotate. The transmission gear 19 on the bottom side of the driven gear 18 rotates accordingly. Through the meshing transmission of the two transmission gears 19, the dispersing shaft 13 is driven to rotate on the bottom side of the support frame 16 and inside the guide shroud 10 to disperse the raw material inside the guide shroud 10. The dispersing shaft 13 drives the auger 14 at the bottom to rotate synchronously, so as to output the raw material inside the guide shroud 10, avoid the raw material from blocking the opening of the guide shroud 10 and affecting the feeding of the raw material, and complete the conveying and pre-processing of the raw material. When it is necessary to clean the residual material, the cylinder cover 2 can be opened to clean the inside of the cylinder body 1.
