[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0027] Reference Figure 1-Figure 4 As shown, the utility model is a silver paste filling device, which is used to directly use the silver paste in the original paste barrel, and includes:

[0028] A cabinet 1 is provided with a material box 11, a slide rail 12 extending along the height direction thereof is provided in the material box 11, a slider 13 is provided on the slide rail 12, and a barrel sleeve 14 for placing a raw pulp barrel is connected to the slider 13;

[0029] A driving source 2, the driving source 2 is installed on the cabinet 1 in parallel with the slide rail 12, and the output end of the driving source 2 extends into the material box 11 and is connected to the slide block 13;

[0030] The dispensing valve 3 is arranged on the cabinet 1;

[0031] The feed pipe 4 has an output end connected to the input end of the dispensing valve 3 , and the input end of the feed pipe 4 extends parallel to the slide rail 12 into the material box 11 and is coaxial with the barrel sleeve 14 , and the input end of the feed pipe 4 is coaxially connected to the piston 5 .

[0032] Specifically, a slide rail 12 is vertically arranged on the inner wall of the material box 11, and a slider 13 is slidably arranged on the slide rail 12. A barrel sleeve 14 is vertically connected to one side of the slider 13. The barrel sleeve 14 is a cylindrical structure with an open top (the inner diameter of the barrel sleeve 14 matches the outer diameter of the original slurry barrel A), and the original slurry barrel can be placed in the barrel sleeve 14; the driving source 2 is vertically connected to the cabinet 1, and the output end of the driving source 2 is connected to the slider 13, and the barrel sleeve 14 can be driven to move in the vertical direction through the driving source 2; the dispensing valve 3 is arranged on the top of the cabinet 1, and the output end of the feeding pipe 4 is connected to the dispensing valve 3, and the input end of the feeding pipe 4 extends vertically downward from the top of the material box 11 to the material box 11, and the section of the feeding pipe 4 in the material box 11 is parallel to the slide rail 12 and coaxial with the barrel sleeve 14, and the input end of the feeding pipe 4 is coaxially connected to the piston 5.

[0033] During the production process, the barrel sleeve 14 is first lowered to a certain height through the driving source 2, so that there is enough space between the barrel sleeve 14 and the piston 5 to place the raw slurry barrel. The raw slurry barrel is placed in the barrel sleeve 14, and then the driving source 2 is controlled to drive the barrel sleeve 14 and the raw slurry barrel therein to move upward to a predetermined height, so that the piston 5 is located at the mouth of the raw slurry barrel, and the preparation work is completed; when filling silver paste, the driving source 2 pushes the raw slurry barrel to move upward, and the piston 5 squeezes the slurry in the raw slurry barrel. The slurry will be input into the dispensing valve 3 through the supply pipe 4, and then the dispensing valve 3 will output it accurately and quantitatively.

[0034] The silver paste filling device of the utility model can directly use the original paste barrel, and there is no need to repack the paste in the original paste barrel before use, which reduces labor costs, reduces the time of the raw material preparation stage, and also reduces the production cycle, while avoiding the loss of raw materials during the repackaging of the paste. The entire silver paste filling device has a simple structure, is easy to install and maintain, and is suitable for practical use.

[0035] Furthermore, a pneumatic valve 6 is provided on the feed pipe 4. Specifically, before replacing the stock slurry barrel, the pneumatic valve 6 is closed, so that the slurry in the feed pipe 4 can be prevented from flowing back into the stock slurry barrel during the material replacement process. The pneumatic valve 6 can be a pneumatic ball valve, which uses compressed air as the opening and closing power, has a simple structure, and operates smoothly.

[0036] Furthermore, a human-machine operation unit 7 is included.

[0037] Furthermore, a controller is also included, which is respectively connected to the driving source 2, the dispensing valve 3, the pneumatic valve 6 and the human-machine operation unit 7. The control command can be input through the human-machine operation unit 7 and the automatic control of the device can be realized through the controller.

[0038] Furthermore, the outer diameter of the piston 5 matches the inner diameter of the original pulp barrel. Specifically, a mounting seat is connected to one side of the slider 13, and a center hole is provided on the mounting seat, and the barrel sleeve 14 is coaxially connected in the center hole.

[0039] Furthermore, seals are provided between the feed pipe 4 and the drive source 2 and the material box 11. Specifically, during the use of the silver paste filling device, it is necessary to ensure that the material box 11 is vacuum, which can reduce the air in the feed pipe 4 and is conducive to the continuity of the slurry output and the accuracy of the output amount.

[0040] Furthermore, the material box 11 is vacuum. Specifically, the material box 11 is a box-shaped structure with one side open, and a door for closing the opening is rotatably connected to the opening of the material box 11 through a hinge, and a door lock structure for locking the door is provided on the door. More preferably, the material box is also provided with an observation window for observing the operating status of each device inside it.

[0041] Reference Figure 2 As shown, further, a cylindrical support portion extending downward from the bottom of the material box 11 is provided, the bottom of the support portion is coaxially connected to the piston 5, and a central passage for the feed pipe 4 to pass through is coaxially provided on the support portion, and the input end of the feed pipe 4 is connected to the inner hole of the piston 5. It can be imagined that the support portion can provide sufficient support for the piston 5 and prevent the feed pipe 4 from being deformed by force during the relative movement between the piston 5 and the original slurry barrel. More preferably, a guide sleeve can be provided above the barrel to guide the piston 5, further improving the stability and reliability of the equipment during operation and ensuring the smooth progress of the production process.

[0042] Furthermore, the piston 5 is a polyurethane piston, which has good corrosion resistance and wear resistance, and the Y-shaped lip structure at the front end of the polyurethane piston is resistant to high pressure, can shrink the outer dimensions, and can adapt to the small mouth of the original slurry barrel.

[0043] Furthermore, the driving source 2 is a cylinder.

[0044] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
