Description

Technical Field

[0001] The invention relates to the technical field of injection molding and injection material, in particular to an injection material device for producing aluminum hoses. Background Art

[0002] In people's daily life and production, various packaging materials are often used to package and store materials. Among them, metal packaging material aluminum hose is a common packaging material, which is suitable for cosmetics, medicine and other industries. Aluminum hose packaging materials are mostly manufactured by injection molding during production, so an injection device is needed during the injection process to facilitate manual operation, and can accurately control the amount and temperature of the injection to improve product quality.

[0003] For example, the existing Chinese patent document CN202222792736.X discloses a material injection device for aluminum hose production, which is provided with a material mixer, a material storage tank and a material guide tank. The material mixer evenly mixes the materials, and the material mixer drives the stirring rod through a first motor to mix and stir the materials. At the same time, the existing Chinese patent document CN202420357572.4 discloses a material injection device for aluminum hose production, which is provided with a stirring component and a heating component, and uses a heating rod and a fan to draw air heated by a heating wire into the material mixer, a conveying mechanism and a material injection mechanism, so as to speed up the heating efficiency of the materials. In the two solutions mentioned above, although a mixer is used to evenly mix the materials, the problem is that after the materials are filled in the mixer, it is necessary to wait for the stirring mechanism in the mixer to complete the stirring process of the materials before continuing with the next step of filling. The existence of this waiting time will undoubtedly slow down the overall progress of the aluminum hose processing, resulting in unsatisfactory filling efficiency and difficulty in meeting those high-intensity and high-efficiency filling requirements.

[0020] Example 1: Please refer to Figure 1 - Figure 3, a feeding device for aluminum hose production shown in the figure comprises a feeding box 1, an auger conveyor 2 and two mixing boxes 3, the auger conveyor 2 is installed on the top of the feeding box 1, and the outer sides of the two mixing boxes 3 are fixedly connected to the feeding box 1 through a bracket; a discharge pipe 13 connected to the bottom of the mixing box 3 through a solenoid valve, and a No. 1 three-way pipe 14 is fixed to the end of the discharge pipe 13 away from the mixing box 3, and the top of the auger conveyor 2 is connected to the bottom of the No. 1 three-way pipe 14 through a pipeline. When the aluminum hose is injected, the material is stirred by the mixing box 3. After the stirring is completed, the solenoid valve is opened, and the material flows from the discharge pipe 13 and the No. 1 three-way pipe 14 and enters the auger conveyor 2, and then the material is evenly discharged into the feeding box 1 through the auger conveyor 2, and then the material can be squeezed out of the feeding box 1 by the pushing function of the feeding box 1 to inject; It also includes: a U-shaped plate 4 fixed on the top of the mixing box 3, a support plate 5 fixed on the top of the U-shaped plate 4, a drive unit 6 installed on the support plate 5, a mixing unit 7 is arranged inside the mixing box 3, transmission units 8 connected to the mixing unit 7 are arranged at both ends of the top of the support plate 5, an end face gear ring 12 is fixed on the top of the mixing box 3, a clutch unit 9 for switching the power of the drive unit 6 is arranged between the two groups of the transmission units 8, a lubrication unit 10 for automatically maintaining the transmission unit 8 is installed on one side of the support plate 5, and the cooperation between the drive unit 6, the transmission unit 8 and the clutch unit 9 is designed to successfully realize the mixing boxes 3 on both sides. The function of being able to switch working states freely, when one mixing box 3 is conveying the processed materials to the auger conveyor 2 for the next step of processing, the mixing box 3 on the other side can immediately start a new mixing task. By using this alternating working mode, the two mixing boxes 3 can continuously perform mixing production, thereby significantly improving the output of the mixing processing work of the injection device. This efficient production method ensures that the mixing output can better meet the needs of fast injection, and ensures that the injection device can always maintain a high working speed without frequent shutdowns due to waiting for the mixing processing of the materials, thereby improving the overall progress of the aluminum hose processing to a certain extent, ensuring production efficiency and product quality; For further information, see Figure 3The driving unit 6 includes a servo motor 601, a driving pulley 602, a transmission belt 603 and a driven pulley 604.

According to the nature of the friction, the rotational movement of the active pulley 602 drives the transmission belt 603 to move through the friction, and the movement of the transmission belt 603 will transfer power to the driven pulley 604. Similarly, relying on the friction between the belt and the driven pulley 604, the driven pulley 604 rotates with the movement of the transmission belt 603, thereby driving the rotating tube 605 to rotate.

The transmission unit 8 is connected, so that the drive unit 6 and the transmission unit 8 on the right mixing box 3 are connected and transmitted, so that the mixing box 3 on this side starts to mix, thereby achieving the purpose of the mixing boxes 3 on both sides mixing in turn, so that one of the mixing boxes 3 transports the processed material to the injection box 1 while the mixing box 3 on the other side starts a new mixing task, so that the two mixing boxes 3 alternately mix and produce, thereby effectively improving the output of the mixing processing work of the injection device, so that the mixing output can better meet the needs of fast injection.

The heads 10066 are evenly distributed on one side of the No. 1 fuel injection pipe 10065, the No. 1 nozzle 10066 is facing the transmission unit 8, the parallel pipe 10064 is connected to the No. 1 fuel injection pipe 10065, the No. 2 fuel injection pipe 10067 is connected to the No. 1 fuel injection pipe 10065 through the parallel pipe 10064, the No. 2 nozzles 10068 are evenly distributed on one side of the No. 2 fuel injection pipe 10067, and the No. 2 nozzles 10068 are arranged toward the end face gear ring 12.

[0030] Principle of automatic maintenance: when the movable seat 902 moves from right to left, it will drive the piston rod 1005 to move from right to left through the connecting block 1007, and then drive the piston block 1004 to move from right to left. At this time, the internal space on the right side of the piston block 1004 and the oil guide cylinder 1002 increases, and the one-way valve of the oil inlet pipe 1003 opens, and the one-way valve of the oil outlet pipe 10061 closes, which will generate negative pressure on the right side of the piston block 1004, and the lubricating oil inside the oil tank 1001 is sucked into the oil guide cylinder 1002 for storage. When the mixing box 3 on the left side finishes mixing, the movable seat 902 will move from left to right again. At this time, the one-way valve of the oil inlet pipe 1003 is closed, the one-way valve of the oil outlet pipe 10061 is opened, and the piston block 1004 moves from left to right. Movement to the right will displace the lubricating oil stored in the oil guide cylinder 1002, and enter the two oil delivery pipes 10063 from the oil outlet pipe 10061, and be sprayed out from the No. 1 nozzle 10066 through the No. 1 oil injection pipe 10065, thereby evenly injecting lubricating oil into the bevel gear set of the transmission unit 8, automatically cooling and lubricating the transmission unit 8. In addition, the lubricating oil in the No. 1 oil injection pipe 10065 will be introduced into the No. 2 oil injection pipe 10067 through the parallel pipe 10064, and sprayed out from the No. 2 nozzle 10068, thereby evenly injecting lubricating oil into the surface of the end gear ring 12, automatically cooling and lubricating the rotation unit 11, ensuring that the transmission parts can be automatically maintained while power switching is in progress, thereby increasing the service life.
