Description

Technical Field

[0001] This utility model relates to the field of planetary mixer technology, and in particular to a discharge device for a double planetary mixer. Background Technology

[0002] In industrial production, material mixing and discharging are crucial steps in many processes. With continuous industrial development, the demands for efficiency, quality, and safety in material handling are increasing. Efficient discharge devices ensure smooth material discharge, improve production efficiency, and guarantee stable material quality, which is essential for enhancing the overall efficiency of the production process. Many industries, including chemicals, food, and building materials, require material mixing and discharging operations; therefore, the development of related technologies plays a vital role in promoting production in these industries.

[0003] Prior to this technical solution, various methods were conventionally used to solve the material discharge problem. For material mixing, ordinary mixing equipment was typically used, utilizing the rotation of the mixing paddle to achieve mixing. For pressing, the pressing equipment was usually operated manually, with the pressing depth and force controlled based on experience. In the venting stage, there was usually no dedicated venting structure; air was expelled relying on the material's own fluidity and gaps. During material storage and transportation, the position of the storage hopper was usually determined by simple fixing devices, lacking precise limiting measures. Controlling the pressing depth also mainly relied on manual observation and adjustment, making precise control difficult.

[0004] The existing technology has significant drawbacks. During the compression process, due to the lack of an effective venting structure, air inside the storage cylinder cannot be effectively expelled, easily leading to excessive pressure within the cylinder and causing air to mix into the material, affecting its quality. Furthermore, the compression depth control is inaccurate, requiring excessive manual intervention, which can easily result in over-compression or under-compression, damaging the cylinder and reducing production efficiency. Moreover, excessive manual intervention also poses safety hazards, increasing the risk of accidents to operators. Utility Model Content

[0006] This application provides a discharge device for a double planetary mixer, which adopts the following technical solution: A discharge device for a dual planetary mixer includes a main frame, a pressing mechanism mounted on the main frame, a storage cylinder, an exhaust structure, an inductive limit switch, and a limiting component. The pressing mechanism includes a pressing plate and a power unit, the power unit driving the pressing plate to move along the inner wall of the storage cylinder. The exhaust structure includes an exhaust pipe penetrating the pressing plate and an exhaust valve mounted on the pressing plate. The inductive limit switch is located at the lower end of the pressing plate and is used to sense the bottom of the storage cylinder and control the pressing mechanism to stop working. The limiting component is used to limit the position of the storage cylinder.

[0007] By adopting the above technical solution, this utility model designs a discharge device for a double planetary mixer. During use, the mixed storage bin is placed below the pressing mechanism. The pressing plate is driven to press the material inside the storage bin. Before pressing begins, the exhaust valve is opened. The power unit of the pressing mechanism drives the pressing plate to move along the inner wall of the storage bin, and air inside the storage bin is discharged through the exhaust pipe. When the inductive limit switch senses the bottom of the storage bin, it controls the power unit to stop working. The main frame provides a stable working platform. The power unit drives the pressing plate to move along the inner wall of the storage bin for pressing. The exhaust structure, consisting of the exhaust pipe and exhaust valve, discharges gas from the storage bin when the pressing plate is pressed down, preventing excessive pressure inside the storage bin or air from mixing into the material. The inductive limit switch senses the bottom of the storage bin and controls the pressing mechanism to stop working, preventing excessive compression and damage to the storage bin. The limit component limits the position of the storage bin, improving discharge safety and material quality, reducing manual intervention, and improving efficiency and safety.

[0014] Preferably, it also includes a vacuum pump, which is installed on the mixer, connected to the storage cylinder through a vacuum pipe, and equipped with a bypass valve and a pressure gauge.

[0015] By adopting the above technical solution, a vacuum operation can be performed on the storage cylinder after stirring during use to prevent air mixed in during the material stirring process from affecting the quality of subsequent materials.

[0018] Preferably, the top of the support frame is provided with a rotating rod, and the limiting component includes a limiting rod rotatably connected to the rotating rod.

[0019] By adopting the above technical solution, the limiting component uses a limiting rod rotatably connected to the rotating rod during use, which can conveniently and flexibly limit the position of the storage cylinder, prevent the storage cylinder from moving horizontally, and further improve the stability and accuracy of the discharge operation.

It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0025] This utility model discloses a discharge device for a double planetary mixer, such as... Figures 1 to 3 As shown, the device includes a main frame 1, a pressing mechanism 2, a storage cylinder 3, an exhaust structure 4, an inductive limit switch 5, and a limit assembly 6. The main frame 1 supports and bears the various components, providing a stable working platform for the entire discharge device. The pressing mechanism 2 is mounted on the main frame 1, and its power unit 22 drives the pressing plate 21 to move along the inner wall of the storage cylinder 3, thereby pressing the material inside the storage cylinder 3. The exhaust pipe 41 of the exhaust structure 4 passes through the pressing plate 21, and the exhaust valve 42 is mounted on the pressing plate 21 to discharge gas from the storage cylinder 3 during the pressing process. The inductive limit switch 5 is located at the lower end of the pressing plate 21 and can sense the bottom of the storage cylinder 3 and control the pressing mechanism 2 to stop working, avoiding over-compression. The limit assembly 6 is used to limit the position of the storage cylinder 3 to prevent displacement of the storage cylinder 3 during the pressing process. This combination achieves the effects of avoiding excessive pressure inside the storage cylinder 3, preventing the material from mixing with air, and avoiding damage to the cylinder due to excessive compression. This is because the exhaust structure 4 can discharge air, the inductive limit switch 5 can control the pressure plate 21 to stop moving, and the limit component 6 can fix the position of the storage cylinder 3.

[0026] Specifically, the main frame 1 is the foundation of the entire discharge device, and it is generally made of metal, such as steel, which has sufficient strength and stability. The main frame 1 can also be integrally formed using a casting process to improve its overall strength and stability.

[0027] The pressing mechanism 2 includes a power unit 22 and a pressing plate 21. The power unit 22 can be a hydraulic cylinder, an electric push rod, etc. Taking a hydraulic cylinder as an example, it consists of a cylinder body, a piston, a piston rod, etc. The cylinder body is fixed on the main frame 1, and the piston rod is connected to the pressing plate 21. When the hydraulic system injects hydraulic oil into the cylinder body, the piston pushes the piston rod to move under the pressure of the hydraulic oil, thereby driving the pressing plate 21 to move along the inner wall of the storage cylinder 3. The pressing plate 21 is a flat plate structure whose shape is adapted to the inner wall of the storage cylinder 3, and can closely fit the inner wall of the storage cylinder 3 to perform the pressing operation. The outer periphery of the pressing plate 21 is provided with a sealing flange 15 that slides and cooperates with the inner wall of the storage cylinder 3. The sealing flange 15 can be made of elastic materials such as rubber, which plays a sealing role and prevents the material from overflowing from the gap between the pressing plate 21 and the inner wall of the storage cylinder 3.

[0028] The exhaust structure 4 includes an exhaust pipe 41 that penetrates the pressure plate 21 and an exhaust valve 42 disposed on the pressure plate 21. The pressure plate 21 has an exhaust hole 7, the inlet end of which is installed inside the exhaust hole 7, and the outlet end of which is located outside the storage cylinder 3. The exhaust pipe 41 can be made of metal or plastic, such as stainless steel or PVC. The exhaust valve 42 can be a manual valve or a solenoid valve. A manual valve requires manual operation to control the opening and closing of the exhaust pipe 41, while a solenoid valve can be automatically controlled by an electrical control system. Before pressing begins, the exhaust valve 42 is opened, and air in the storage cylinder 3 is discharged through the exhaust pipe 41. When material is observed, the exhaust valve 42 is closed to avoid excessive venting.

[0029] An inductive limit switch 5 is located at the lower end of the pressure plate 21, and its contacts are isolated from the pressure plate 21 by an insulating sleeve 8. The inductive limit switch 5 can accurately sense the metal at the bottom of the storage cylinder 3, and the insulating sleeve 8 serves to insulate and protect the contacts. The insulating sleeve 8 can be made of insulating materials such as plastic or rubber. When the inductive limit switch 5 senses the bottom of the storage cylinder 3, it will send a signal to control the power unit 22 of the pressing mechanism 2 to stop working, thereby precisely controlling the pressing depth.

[0030] The limiting component 6 is used to limit the position of the storage cylinder 3. A pulley 11 is provided at the bottom of the storage cylinder 3, and a slide rail 12 is provided at the bottom of the pulley 11. The slide rail 12 is mounted on a support frame 13 at the bottom of the main frame 1, and the pulley 11 is slidably connected to the slide rail 12. This allows the storage cylinder 3 to slide on the slide rail 12 via the pulley 11, facilitating the movement of the storage cylinder 3 below the pressure plate 21 by the operator. A rotating rod 14 is provided at the top of the support frame 13, and the limiting component 6 includes a limiting rod 61 rotatably connected to the rotating rod 14. When the storage cylinder 3 moves to the designated position, the limiting rod 61 is rotated to lock the storage cylinder 3, preventing horizontal movement of the storage cylinder 3 during the pressing process.

[0031] In addition, the main frame 1 has two workstations. The pressing mechanism 2 is located in one workstation, and the mixer 9 is located in the other workstation. The mixer 9 is mounted on the storage cylinder 3 and has a feeding port and an observation window. The mixer 9 is used to stir the material in the storage cylinder 3, ensuring thorough mixing. The feeding port facilitates adding material to the storage cylinder 3, and the observation window allows operators to easily observe the material inside the cylinder.

[0032] It also includes a vacuum pump 10, which is mounted on the mixer 9 and connected to the storage cylinder 3 via an extraction pipe. The vacuum pump 10 is equipped with a bypass valve and a pressure gauge. The vacuum pump 10 assembly includes a pump body, an extraction pipe, a bypass valve, and a pressure gauge. The pump body can be a rotary vane vacuum pump 10, a screw vacuum pump 10, etc. The extraction pipe connects the pump body and the storage cylinder 3 to extract air from the storage cylinder 3. The bypass valve regulates the flow rate and pressure of the extracted air, and the pressure gauge displays the pressure inside the storage cylinder 3. After mixing, the vacuum pump 10 performs a vacuuming operation on the storage cylinder 3 to prevent air mixed in during the mixing process from affecting the quality of subsequent materials.

[0033] The combination logic of these components is as follows: The mixer 9 first mixes the material in the storage cylinder 3, then the vacuum pump 10 evacuates the storage cylinder 3. Afterwards, the operator pushes the storage cylinder 3 along the slide rail 12 via the pulley 11 to the pressure plate 21, and the position is fixed by rotating the limit rod 61. Before pressing begins, the exhaust valve 42 is opened, and the power unit 22 of the pressing mechanism 2 drives the pressure plate 21 to move along the inner wall of the storage cylinder 3. Air inside the storage cylinder 3 is discharged through the exhaust pipe 41. When material is seen, the exhaust valve 42 is closed. When the inductive limit switch 5 senses the bottom of the storage cylinder 3, it controls the power unit 22 to stop working. The combined effect is to achieve safe, efficient, and accurate material discharge, improving material quality and production efficiency.

[0034] The implementation principle of this embodiment is as follows: The discharge device of the double planetary mixer 9 in this embodiment solves the problems of incomplete air discharge and excessive material compression in the prior art through the coordinated work of various components. The exhaust structure 4 effectively discharges air, avoiding excessive pressure in the storage cylinder 3 or air mixing into the material due to air compression; the inductive limit switch 5 precisely controls the stroke of the pressure plate 21 to prevent excessive compression and damage to the storage cylinder 3; the limit component 6 fixes the position of the storage cylinder 3 to ensure the stability of the material compression operation. The entire device has a high degree of automation, reduces manual intervention, improves production efficiency and safety, and makes significant improvements to the prior art.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
