Description

[Technical field]

[0001] The utility model belongs to the technical field of powder filling, in particular to a high-efficiency powder pressing and suction device. [Background technology]

[0002] When coffee capsules are filled with powder, it is easy to cause the powder to scatter because the powder is dropped at the mouth of the cup. The powder falls on the edge of the cup, which will lead to poor sealing of the sealing film, and then the quality of the product produced is low. Therefore, after the addition is completed, the powder in the cup needs to be pressed to make the upper surface of the powder flat, and then the excess powder on the edge of the cup is sucked away. For example, a powder suction mechanism disclosed in Chinese patent announcement No. CN215426174U includes a gantry, a cylinder, a cylinder push plate, a support column, a powder suction plate, a powder suction cover, a powder suction tube, a vacuum generator, a powder pressing assembly and a mold plate. The crossbeam of the gantry is equipped with a cylinder, and the piston rod flange of the cylinder is equipped with a cylinder push plate. The cylinder push plate is fixedly connected to the powder suction plate below it through two support columns. A powder suction cover is installed at the lower end of the powder suction plate. The lower end of the powder suction cover is provided with an adsorption cavity. A powder suction tube communicating with the adsorption cavity is installed on the powder suction plate. The powder suction tube is connected to the vacuum generator through a pipeline. An elastically arranged powder pressing component is installed on the powder suction plate. The powder pressing component passes through the powder suction cover. A mold plate for placing the cup body is docked below the powder suction cover. The opposite surfaces of the powder suction cover and the mold plate are provided with matching card slots. The powder suction cover and the mold plate are closed to form a closed cavity. Although the above scheme can realize powder pressing and powder suction, there are still the following two problems:

[0003] (1) The powder pressing rod needs to be driven by a cylinder to press the powder, and a gantry frame needs to be set to fix the cylinder. The entire mechanism is located above the mold plate, which occupies a large space and is not conducive to the layout of other mechanisms above the mold plate;

[0004] (2) There is only one powder pressing component, which can only press and suck powder into one cup at a time, resulting in low filling production efficiency and failure to meet production needs.

[0005] Therefore, it is necessary to provide a high-efficiency powder pressing and powder suction device to solve the above technical problems. [Contents of the utility model]

[0032] Please refer to Figure 1-Figure 5 The present embodiment is a high-efficiency powder pressing and powder suction device. The high-efficiency powder pressing and powder suction device 100 includes a mold plate for placing a cup 200, a mounting base 2 arranged above the mold plate, a plurality of powder pressing modules 3 arranged inside the mounting base 2, and a pushing module arranged below the mold plate and used to drive the cup 200 to move upward to contact with the powder pressing module 3 to achieve powder pressing; the mounting base 2 includes a converging channel 21 extending upwardly and penetrating the upper surface, and a plurality of converging channels 21 extending downwardly and penetrating the lower surface for the cup 200 to enter. There are a plurality of avoidance holes 22, and a powder suction tube 1 is installed at the upper end of the converging channel 21. The avoidance holes 22 are opened on the side facing the converging channel 21 and are connected with the converging channel 21. When the pushing module pushes the cup 200 upward into place, the outer wall of the powder pressing module 3, the cup mouth 201, and the hole wall of the avoidance hole 22 together form a accommodating space 4 for residual powder, and a powder movement channel 5 is formed inside the mounting base 2, which enters from multiple accommodating spaces 4 into the converging channel 21 and then enters into the powder suction tube 1 through the converging channel 21.

[0033] The mounting base 2 includes a supporting base 23 at the bottom and a mounting upper base 24 mounted above the supporting base 23 and used to mount the powder pressing module 3 . The avoidance hole 22 is arranged on the supporting base 23 and passes through the upper and lower surfaces of the supporting base 23 .

[0034] The lower end of the avoidance hole 22 is provided with an annular support 221 for supporting the cup mouth 201, and the annular support 221 is formed by extending from the hole wall of the avoidance hole 22 to the center. The upper end of the annular support 221 is arranged in the same shape as the cup mouth 201 to stably support the cup 200, and the opening diameter of the lower end of the annular support 221 gradually increases, which guides the cup 200 to rise, so that the cup 200 can smoothly enter the avoidance hole 22.

[0035] The support base 23 is provided with a convergence groove 231 extending upward from the inside and penetrating the upper surface, and the mounting upper seat 24 is provided with a through hole 241 penetrating the upper and lower surfaces. The convergence groove 231 and the through hole 241 are connected up and down to form a convergence channel 21. The lower end of the through hole 241 is set to a trumpet structure with a gradually increasing diameter so that the powder can be sucked out smoothly. The avoidance holes 22 are all opened on the side facing the convergence groove 231 and communicate with the convergence groove 231.

[0036] The upper seat 24 is installed with an installation hole 242 for installing the powder pressing module 3 at the position where the avoidance hole 22 is located, and the diameter of the avoidance hole 22 is larger than the diameter of the installation hole 242; at the bottom of the installation hole 242, an annular ridge 243 is provided which protrudes from the lower surface of the support base 23 and extends into the avoidance hole 22 to achieve sealing.

[0037] The powder pressing module 3 includes a powder pressing head 31 installed in the mounting hole 242 and used to flatten the powder in the cup 200, and a pushing sleeve 32 elastically sleeved on the outer periphery of the powder pressing head 31 and used to push the cup 200 downward after the powder is sucked. The powder pressing head 31 is installed in the mounting hole 242 of the fixed mounting upper seat 24 by screws.

[0038] The powder pressing head 31 includes a mounting portion at the upper end, a tapered connecting portion in the middle, and a material pressing portion at the lower end extending into the cup 200. The diameter of the mounting portion is smaller than the diameter of the material pressing portion. Therefore, the tapered connecting portion in the middle is a tapered structure with a small top and a large bottom. The mounting portion is provided with a threaded hole for mounting with a screw. The powder pressing head 31 is a cylindrical structure with a flat bottom.

[0039] The push sleeve 32 is provided with a profile hole that is through from top to bottom and is shaped like the lower end of the powder pressing head 31. The profile hole includes a profile hole section a that is shaped like the outer wall of the mounting part of the powder pressing head 31 at the upper end, a profile hole section b that is shaped like the tapered connecting part in the middle, and a profile hole section c that is shaped like the outer wall of the material pressing part at the lower end. The aperture of the profile hole section a is smaller than that of the profile hole section c. When the push sleeve 32 is sleeved on the outer periphery of the powder pressing head 31, the profile hole section b of the push sleeve 32 is supported on the tapered connecting part provided in the middle of the powder pressing head 31, so as to limit the tapered connecting part in the vertical direction.

[0040] The push sleeve 32 includes a first section at the upper end and a second section at the lower end. The diameter of the first section is smaller than the diameter of the second section. Therefore, a step plane is formed at the connection between the first section and the second section. A spring 33 is sleeved on the outer periphery of the first section. The lower end of the spring 33 abuts on the step plane and the upper end abuts on the inner wall of the mounting hole 242.

[0041] The second section is provided with a tapered tip 321 at the contour hole c section, which has a gradually decreasing diameter and can extend into the cup 200 to achieve contour sealing with the inner wall of the cup 200. The outer wall of the tapered tip 321 is a smooth plane.

[0042] This solution is provided with three powder pressing modules 3, and three avoidance holes 22 are correspondingly provided on the mounting base 2. The three powder pressing modules 3 are arranged in a triangle, and the converging channel 21 is arranged in the center of the three powder pressing modules 3. The layout is compact and the occupied space is extremely small.

[0043] The powder suction tube 1 is a "U"-shaped structure, one end of which is fixed on the mounting seat 24 and communicated with the through hole 241, and the other end is connected to the vacuum generator (not shown in the figure). The support base 23 is provided with a guide support hole 232 for mounting and supporting the powder suction tube 1.

[0044] When the high-efficiency powder pressing and sucking device 100 of the present invention is applied, when multiple cups 200 on the mold plate are filled with powder, the pushing module pushes the multiple cups 200 on the mold plate upward at the same time, so that the cups 200 enter the avoidance holes 22 on the supporting base 23. When the cups 200 are pushed upward, the conical tip 321 of the pushing sleeve 32 abuts against the inner wall of the cup 200 and moves upward. The spring 33 is compressed. When the cups 200 are pushed into place, the pressing force of the powder pressing head 31 is released. The material part is pressed tightly against the upper end of the powder inside the cup 200 to flatten the powder. The cup mouth 201 is supported on the annular support 221 of the avoidance hole 22 and the cup mouth 201 is in contact and sealed with the annular support 221. Therefore, the outer wall of the second section of the push sleeve 32, the cup mouth 201, the hole wall of the avoidance hole 22 and the annular convex ridge 243 at the bottom of the upper seat 24 are jointly surrounded to form a residual powder accommodating space 4. Multiple cups 200 are formed with multiple accommodating spaces 4 in multiple avoidance holes 22. A plurality of accommodating spaces 4 are simultaneously connected to the converging channel 21, so a powder movement channel 5 is formed inside the mounting base 2, which enters from the plurality of accommodating spaces 4 into the converging channel 21 and then enters into the powder suction tube 1 via the converging channel 21. The powder movement channel 5 is a closed channel, and is connected to a vacuum generator at the other end of the powder suction tube 1. The vacuum generator starts working, and the air in the powder movement channel 5 is rapidly discharged. As the amount of air in the powder movement channel 5 decreases, the exhaust volume decreases rapidly, and the vacuum degree of the powder movement channel 5 increases rapidly. After reaching a certain vacuum degree, the powder at the cup mouth 201 of the powder movement channel 5 is sucked clean. After the work is completed, the vacuum generator stops working and the push module descends. At this time, the cup 200 has a tendency to descend due to its own gravity, and the reset of the spring 33 will cause the push sleeve 32 to move downward, so that the push sleeve 32 pushes the cup 200 downward to its original position on the mold plate, and the powder pressing and suction action is completed, waiting to enter the next cycle.

[0045] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
