Description

Technical Field

[0001] This utility model relates to the field of mixer technology, and in particular to an apparatus for preparing antioxidant copper paste that is convenient for printing copper products. Background Technology

[0002] Copper paste is a functional paste composed of micro / nano copper powder, organic carrier (resin / solvent), glass powder (flux), additives, etc., and is widely used in electronics, photovoltaics, new energy and other fields. The production process of copper paste involves multiple process steps, the initial step of which is the preparation of copper paste, including raw material mixing, stirring, sintering, and heat treatment. The mixing and stirring step is very important as the initial step, and the mixing of materials is usually accomplished by a mixer. A copper paste mixer is a device specifically used for mixing copper paste (copper powder, organic carrier, solvent, etc.), and is widely used in electronic packaging, photovoltaics, new energy batteries, conductive paste preparation. This invention addresses the following issues regarding copper paste mixing: While there are many types of existing copper paste mixers, most are general-purpose mixers. Firstly, the mixing structure of these general-purpose mixers only mixes the central part of the material, with the surrounding parts relying on the central material for mixing. This results in slow mixing speeds for highly viscous copper paste due to its fluidity, impacting preparation efficiency. Secondly, existing equipment typically mixes under normal pressure, allowing air to enter the material along with its flow without effective expulsion, leading to a large number of air bubbles in the final product and questionable mixing quality, thus affecting preparation quality. Therefore, this invention improves upon existing equipment to address these problems. Utility Model Content

[0020] In this utility model, to solve the problems of low stirring speed and poor stirring quality when using ordinary stirring structures and conventional stirring environments in existing stirring equipment, the following technical solution is adopted: The lifting component includes a first motor 6, which is installed and fixed in the middle of the opposite surface of the support column 2. A threaded rod 7 is connected to the bottom surface of the first motor 6. Both ends of the threaded rod 7 are rotatably connected to the opposite surface of the support column 2. A threaded seat 8 is sleeved on the outer side of the threaded rod 7. An installation plate is fixedly connected to the threaded seat 8 in the opposite direction. An electric push rod 9 is horizontally installed and fixed on the installation plate. An anti-slip pad is fixedly connected to the telescopic end of the electric push rod 9. A clamping ring 10 is horizontally fixed between the bottom ends of the installation plate. A loading hopper 11 is mounted on the clamping ring 10. Multiple casters are evenly fixed to the bottom of the loading hopper 11. Through the cooperation of the loading hopper 11 and the first motor 6, the loading hopper 11 can freely load or stir, improving loading efficiency. The vacuum assembly includes a sealing ring 12, which is fixed to the bottom of the suction cylinder 13. The top of the suction cylinder 13 is fixed to the center of the bottom of the transmission box 3. A sealing rotating disk 14 is rotatably connected to the upper end of the suction cylinder 13. The sealing rotating disk 14 has sealing holes that cooperate with the stirring assembly. The sealing ring 12 ensures a sealed environment when the loading hopper 11 and the suction cylinder 13 come into contact, improving sealing performance. The stirring assembly includes a... The second motor 15 is mounted and fixed on the upper side of the support column 2. A first pulley 16 is connected to the upper end of the second motor 15, and a first belt 17 is fitted onto the first pulley 16. The other end of the first belt 17 is fitted onto the second pulley 18, which is coaxially fixed to the top of the central shaft 19. The central shaft 19 is rotatably connected to the middle of the transmission box 3. A drive gear 20 is horizontally fixed to the middle of the outer side of the central shaft 19. The central shaft 19 passes through the sealed rotating disc 14 and has two connecting brackets 21 fixed to its bottom and lower-middle ends. Spiral stirring wires 22 are evenly fixed between the connecting brackets 21. A third motor 23 is mounted and fixed on the other side of the support column 2. The third motor 23 is connected to the top of the third pulley 24. The outer side of the third pulley 24 is fitted with the second belt 25. The other end of the second belt 25 is fitted on the fourth pulley 26. The lower end of the fourth pulley 26 is fixedly connected to the revolution frame 27. The revolution frame 27 is rotatably connected to the revolution shaft 28. The outer side of the revolution shaft 28 is fixedly connected to the driven gear 29. The driven gear 29 meshes with the driving gear 20. The revolution shaft 28 passes through the sealed rotating disk 14 and is horizontally fixed to the stirring disk 30.

[0021] Working Principle: In the use of this utility model, firstly, power is supplied to all electrical equipment. Then, the vacuum cylinder 13 and the vacuuming device are connected through the vacuum port 4. Next, the loading barrel 11 is removed from the clamping ring 10, and a properly proportioned mixed raw material is poured into the loading barrel 11. Then, the loading barrel 11 is reinstalled on the clamping ring 10. Then, the electric push rod 9 is started through the control cabinet 5 to clamp and fix the loading barrel 11. Then, the first motor 6 is started through the control cabinet 5 to drive the threaded rod 7 to rotate, thereby driving the threaded seat 8 to rise. Finally, the top surface of the loading barrel 11 abuts against the bottom surface of the vacuum cylinder 13 and squeezes the sealing ring 12 to ensure sealing. Then, the vacuuming device draws a vacuum into the vacuum cylinder 13 to prevent the material from entering the vacuum during mixing. Air is mixed to form bubbles. Then, the second motor 15 and the third motor 23 are started through the control cabinet 5. The second motor 15 transmits rotational power through the first belt 17 to rotate the central shaft 19, which in turn drives the drive gear 20 to rotate. The third motor 23 transmits rotational power through the second belt 25 to rotate the orbital frame 27 in the opposite direction around the central shaft 19, which in turn drives the orbital shaft 28 around the orbital frame 27 to rotate around the central shaft 19. At the same time, since the driven gear 29 meshes with the drive gear 20, the orbital frame 27 rotates in the opposite direction around the central shaft 19 while the orbital shaft 28 rotates around itself. This ultimately enables the spiral stirring wire 22 and the stirring plate 30 to rotate on their own axis and revolve around the central shaft 19, thus improving the mixing quality.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
