Description

Technical Field

[0001] This application relates to the field of molding equipment technology, specifically to a multi-screw discharge kneader for preparing aluminum silver paste. Background Technology

[0002] In the production process of aluminum silver paste, the kneading process is crucial, as it plays a decisive role in the performance of the final product.

[0003] As a pigment that undergoes special processing and surface treatment, aluminum silver paste requires aluminum flakes with smooth and flat surfaces, neat edges, regular shapes, and concentrated particle size distribution to achieve excellent compatibility with coating systems.

[0004] During operation, the two kneading rods continuously move relative to each other at a preset speed ratio. When the material enters the kneading chamber, the rotating kneading rods push the material from one end of the chamber to the other through the pushing force of the spiral ridges. At the same time, the gap between the rod and the chamber wall, as well as the meshing action between the two rods, generate strong shearing, squeezing and tumbling effects on the material. For example, high-viscosity paste-like materials will be repeatedly torn and kneaded under the grip of the kneading rods. The originally dispersed solid particles will gradually merge with the liquid medium under the action of continuous mechanical force to form a uniform colloidal state. For materials containing multiphase components such as fibers and powders, the rotation of the kneading rods can break the agglomeration structure inside the material, allowing different components to achieve molecular-level mixing through high-frequency contact.

[0005] During the kneading process, existing kneading devices only work on the material once, which can easily lead to insufficient kneading of the material.

[0006] Therefore, it is necessary to provide a multi-screw discharge kneader for aluminum silver paste preparation to solve the above problems. Utility Model Content

[0007] The technical solution adopted by this application to solve its technical problem is: a multi-screw discharge kneading machine for preparing aluminum silver paste, including a frame assembly, the frame assembly including a first mounting plate and a second mounting plate, a kneading assembly disposed between the first mounting plate and the second mounting plate, the kneading assembly including a kneading assembly including a kneading barrel, a second kneading rod and a first kneading rod disposed inside the kneading barrel, one end of the second kneading rod and the first kneading rod penetrating through the kneading barrel and extending to the outside of the kneading barrel, the ends of the second kneading rod and the first kneading rod respectively being equipped with a first driven gear and a second driven gear, a material turning fan blade is also installed inside the kneading barrel, one end of the material turning fan blade penetrating through the kneading barrel and fixedly installed with a third driven gear, and a feeding assembly for feeding materials to the outside is installed on the top of the kneading barrel.

[0008] The third driven gear, the first driven gear, and the second driven gear are meshed with a first drive gear at their middle parts. A driver is provided on one side of the first drive gear. The driver is mounted on one side of the second mounting plate, and the output shaft of the driver passes through the second mounting plate and is fixedly connected to the first drive gear.

[0009] The feeding assembly includes a mounting ring communicating with the kneading barrel. A feeding shell is mounted on the top of the mounting ring. A "protruding" groove is opened inside the feeding shell. A support frame connected to the inner wall of the feeding shell is fixedly mounted in a larger part of the feeding shell. A trigger rod is provided in the middle of the support frame, passing through the support frame and slidably connected thereto. A sealing plate is provided on the trigger rod. The sealing plate seals a smaller part of the "protruding" groove. An elastic element is provided between the sealing plate and the support frame. The elastic element is located on the outer wall of the trigger rod.

[0010] The bottom of the second mounting plate is fixedly connected to an angled plate, and the bottom of the angled plate is fixedly connected to a base plate. The bottom of the first mounting plate is fixedly connected to the top of the base plate.

[0011] The bottom of the kneading barrel is provided with a discharge port, and the turning fan blades are installed at the bottom of the kneading barrel.

[0012] The kneading assembly is externally mounted with four mounting rods, which are respectively fixedly connected to the first mounting plate and the second mounting plate.

[0013] The ratio of the size of the sealing plate to the larger size of the "protrusion" groove inside the feed housing is 1:2.

[0014] The beneficial effects of this application are: When the second driven gear, the third driven gear, and the first driven gear rotate, they will drive the connected material-turning fan blades, the first kneading rod, and the second kneading rod to rotate. When the first and second kneading rods rotate, they will knead the material once. When the material is kneaded and falls to the bottom of the kneading barrel, the material-turning fan blades will turn the material to the top of the kneading barrel for a second kneading. This process is repeated to achieve multiple kneading effects. By setting up the kneading components, the device can help to knead the material multiple times, achieving more thorough processing of the material.

[0015] When the sealing plate moves, it compresses the elastic element. When the sealing plate moves, the feeding component is in the normally open state, realizing the feeding of the device. By setting the feeding component, the feeding position can be kept in a sealed state when the device is working, avoiding the problem of internal material splashing out of the device when the device is working.

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0019] like Figures 1-4 As shown: Example 1: This application provides a multi-screw discharge kneading machine for preparing aluminum silver paste, including a frame assembly 1. The frame assembly 1 includes a first mounting plate 102 and a second mounting plate 104. A kneading assembly 2 is disposed between the first mounting plate 102 and the second mounting plate 104. The kneading assembly 2 includes a kneading assembly 204, which includes a kneading barrel 2041. A second kneading rod 2044 and a first kneading rod 2043 are disposed inside the kneading barrel 2041. One end of the second kneading rod 2044 and the first kneading rod 2043 penetrates the kneading barrel 2041 and extends to the outside of the kneading barrel 2041. A first driven gear 203 and a second driven gear 206 are respectively installed at the ends of the second kneading rod 2044 and the first kneading rod 2043. A material-turning fan blade 2042 is also installed inside the kneading barrel 2041. One end of the material-turning fan blade 2042 penetrates the kneading barrel 2041 and is fixedly installed with a third driven gear. 207, a first drive gear 202 meshes with the middle of the third driven gear 207, the first driven gear 203, and the second driven gear 206. A driver 201 is provided on one side of the first drive gear 202. The driver 201 is installed on one side of the second mounting plate 104. The output shaft of the driver 201 passes through the second mounting plate 104 and is fixedly connected to the first drive gear 202. An angled plate 103 is fixedly connected to the bottom of the second mounting plate 104. A base plate 101 is fixedly connected to the bottom of the angled plate 103. The bottom of the first mounting plate 102 is fixedly connected to the top of the base plate 101. A discharge port is opened at the bottom of the kneading barrel 2041. A turning fan blade 2042 is installed at the bottom of the inside of the kneading barrel 2041. Four mounting rods 205 are installed on the outside of the kneading assembly 204. The four mounting rods 205 are fixedly connected to the first mounting plate 102 and the second mounting plate 104 respectively.

[0020] When the device is working, after the material enters the kneading assembly 204, the driver 201 starts to work. When the driver 201 is working, it drives the first drive gear 202, which is fixedly connected to the output shaft of the driver 201, to work. When the first drive gear 202 is working, it drives the second driven gear 206, the third driven gear 207, and the first driven gear 203 that are meshed with it to rotate. When the second driven gear 206, the third driven gear 207, and the first driven gear 203 rotate, they drive the material-turning fan blade 2042, the first kneading rod 2043, and the second kneading rod 2044 connected to them to rotate. When the first kneading rod 2043 and the second kneading rod 2044 rotate, they knead the material once. When the material is kneaded and falls to the bottom of the kneading barrel 2041, the material-turning fan blade 2042 flips the material to the top of the kneading barrel 2041 for a second kneading. This process is repeated to achieve the effect of multiple kneading.

[0021] By incorporating the kneading component 2, the device can knead the material multiple times, achieving more thorough processing of the material.

[0022] Example 2: A feeding assembly 3 for feeding materials is installed on the top of the kneading barrel 2041 and communicates with the outside. The feeding assembly 3 includes a mounting ring 302 that communicates with the kneading barrel 2041. A feeding shell 301 is installed on the top of the mounting ring 302. A "protruding" groove is opened inside the feeding shell 301. A support frame 303 connected to the inner wall of the feeding shell 301 is fixedly installed in a larger part of the feeding shell 301. A trigger rod 304 is provided in the middle of the support frame 303 and is slidably connected to the support frame 303. A sealing plate 305 is provided on the trigger rod 304. The sealing plate 305 seals the smaller part of the "protruding" groove. An elastic element 306 is provided between the sealing plate 305 and the support frame 303. The elastic element 306 is located on the outer wall of the trigger rod 304. The ratio of the size of the sealing plate 305 to the larger size of the "protruding" groove inside the feeding shell 301 is 1:2.

[0023] When the user adds material, the user can first push the trigger rod 304, which will cause the trigger rod 304 to move the sealing plate 305. When the sealing plate 305 moves, it will no longer seal the feeding shell 301. When the sealing plate 305 moves, it will compress the elastic element 306. When the sealing plate 305 moves, the feeding assembly 3 is in the normally open state, realizing the feeding of the device.

[0024] By incorporating a feeding assembly 3, the feeding position can be sealed during operation, preventing internal materials from splashing out of the device.

[0025] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
