This high-efficiency variable frequency automatic quantitative packaging machine for ultrafine powders has a reasonable design, high packaging accuracy, fast speed, and adjustable bag support plate height, making it suitable for various packaging bag specifications and suitable for large-scale promotion.

[0004] However, the above-mentioned device still has the following problems during implementation:

[0005] When automatic packaging machines are packaging some ultrafine powder materials, due to the strong adsorption of the powder materials, some of the material will easily stick to the inner wall of the hopper, resulting in inaccurate weight of the packaged product and thus affecting the packaging effect. Utility Model Content

[0006] The purpose of this invention is to provide a high-efficiency variable frequency automatic quantitative packaging machine for ultrafine powders to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A high-efficiency variable frequency automatic quantitative packaging machine for ultrafine powder includes a machine body, a hopper, and a controller. The hopper and the controller are respectively fixedly installed on one side of the machine body. A mounting frame is fixedly connected to one side of the hopper, and a striking mechanism is provided on one side of the mounting frame.

[0009] The striking mechanism includes a motor fixedly mounted on one side of the mounting frame. The output end of the motor extends through to one side of the mounting frame and is fixedly connected to a cam. Both sides of the cam are provided with extrusion plates. A transmission rod is provided on the side of the extrusion plate away from the cam. A positioning block is sleeved on the surface of the transmission rod. One side of the positioning block is fixedly connected to one side of the hopper. A linkage plate is fixedly connected to one end of the transmission rod. A striking rod is fixedly connected to one side of the linkage plate. A spring is sleeved on the surface of the transmission rod. One end of the spring is fixedly connected to one side of the extrusion plate. The other end of the spring is fixedly connected to one side of the positioning block. An air jet mechanism is provided on one side of the extrusion plate.

[0010] Preferably, the jetting mechanism includes two push rods fixedly connected to one side of the extrusion plate. A gas collection box is provided on one side of each push rod. One side of the gas collection box is fixedly connected to one side of the discharge hopper. One end of each push rod extends into the interior of the gas collection box and is fixedly connected to a push block. An air inlet pipe is fixedly connected to one side of the gas collection box, and a jetting pipe is fixedly connected to the other side of the gas collection box. One end of the jetting pipe is fixedly connected to one side of the discharge hopper. A one-way valve is fixedly installed on the surface of the air inlet pipe, and a one-way pressure valve is fixedly installed on the surface of the jetting pipe.

[0011] Preferably, a piston plate is fixedly connected to one side of the push block, and the piston plate is made of rubber.

[0012] Preferably, a bearing is provided on one side of the cam, and the cam is rotatably connected to the inner wall of the mounting bracket through the bearing.

[0014] Preferably, buffer plates are fixedly connected to both sides of the hopper, and the buffer plates are sloped around their perimeter.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model, by setting a striking mechanism, can start the motor and drive the cam to rotate while packaging. When the cam rotates, the protruding end contacts the extrusion plate, which pushes the extrusion plate to move away from the cam. At the same time, it drives the transmission rod, linkage plate and striking rod to move, and compresses the spring. When the cam rotates to the point where it is no longer in contact with the extrusion plate, the elastic force generated by the spring will push the extrusion plate to reset suddenly. At the same time, it drives the transmission rod, linkage plate and striking rod to reset suddenly. The striking rod will strike the buffer plate to generate vibration, which is then transmitted to the hopper to shake off the material adhering to its inner wall, thereby improving the packaging effect.

[0017] 2. By setting up an air jet mechanism, this utility model can achieve the following: when the extrusion plate moves back and forth, when the extrusion plate moves closer to the cam, it will drive the push rod, push block and piston plate to move closer to the cam. At this time, the air collection box is under negative pressure, and the gas can easily enter the air collection box through the air inlet pipe. When the extrusion plate moves away from the cam, it will drive the push rod, push block and piston plate to move away from the cam. The piston plate will squeeze the gas. When the gas pressure in the air collection box reaches the limit of the one-way pressure valve, the gas will be sprayed into the hopper through the air jet pipe, blowing off the material adhering in the hopper.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 - Figure 5 This utility model provides a technical solution:

[0026] Example 1:

[0027] A high-efficiency variable frequency automatic quantitative packaging machine for ultrafine powder includes a machine body 1, a hopper 2 and a controller 3. The hopper 2 and the controller 3 are respectively fixedly installed on one side of the machine body 1. A mounting frame 4 is fixedly connected to one side of the hopper 2, and a striking mechanism is provided on one side of the mounting frame 4.

[0028] The striking mechanism includes a motor 5 fixedly mounted on one side of the mounting frame 4. The output end of the motor 5 extends through to one side of the mounting frame 4 and is fixedly connected to a cam 6. Both sides of the cam 6 are provided with extrusion plates 7. A transmission rod 8 is provided on the side of the extrusion plate 7 away from the cam 6. A positioning block 9 is sleeved on the surface of the transmission rod 8. One side of the positioning block 9 is fixedly connected to one side of the hopper 2. One end of the transmission rod 8 is fixedly connected to a linkage plate 10. One side of the linkage plate 10 is fixedly connected to a striking rod 11. A spring 12 is sleeved on the surface of the transmission rod 8. One end of the spring 12 is fixedly connected to one side of the extrusion plate 7. The other end of the spring 12 is fixedly connected to one side of the positioning block 9. An air jet mechanism is provided on one side of the extrusion plate 7.

[0029] In this embodiment, considering that when the automatic packaging machine packages some ultrafine powder materials, due to the strong adsorption of the powder materials, some materials may easily adhere to the inner wall of the feed hopper 2, resulting in inaccurate weight of the packaged product and thus affecting the packaging effect, a tapping mechanism is set up so that the motor 5 can be started at the same time as packaging, driving the cam 6 to rotate. Figure 4 When the cam 6 rotates, its protruding end contacts the extrusion plate 7, which pushes the extrusion plate 7 to move away from the cam 6. At the same time, it drives the transmission rod 8, the linkage plate 10 and the striking rod 11 to move, and it also compresses the spring 12. When the cam 6 rotates to the point where it is no longer in contact with the extrusion plate 7, the elastic force generated by the spring 12 will push the extrusion plate 7 to reset suddenly. At the same time, it drives the transmission rod 8, the linkage plate 10 and the striking rod 11 to reset suddenly. The striking rod 11 will strike the buffer plate 22 to generate vibration, which is then transmitted to the hopper 2 to shake off the material adhering to its inner wall, thereby improving the packaging effect.

[0030] It should be noted that S1 is the movement trajectory of cam 6, and S2 is the movement trajectory of extrusion plate 7.

[0031] A bearing 23 is provided on one side of the cam 6, and is rotatably connected to the inner wall of the mounting bracket 4 through the bearing 23.

[0032] In this embodiment, by setting the bearing 23, the cam 6 can be supported, and its stability and smoothness during rotation can be improved.

[0033] A guide hole 21 is provided on one side of the positioning block 9, and the guide hole 21 is used in conjunction with the transmission rod 8.

[0034] In this embodiment, by providing a guide hole 21, the movement trajectory of the transmission rod 8 can be restricted, so that it can only move back and forth along the guide hole 21.

[0035] Both sides of the hopper 2 are fixedly connected to buffer plates 22, and the buffer plates 22 are all sloping.

[0036] In this embodiment, by setting a buffer plate 22, the striking rod 11 can be prevented from directly striking the surface of the hopper 2, which plays a protective role and extends the service life of the hopper 2.

[0037] Example 2:

[0038] The jetting mechanism includes two push rods 13 fixedly connected to one side of the extrusion plate 7. A gas collection box 14 is provided on one side of the push rod 13. One side of the gas collection box 14 is fixedly connected to one side of the discharge hopper 2. One end of the push rod 13 passes through the interior of the gas collection box 14 and is fixedly connected to a push block 15. An air inlet pipe 16 is fixedly connected to one side of the gas collection box 14, and a jetting pipe 17 is fixedly connected to the other side of the gas collection box 14. One end of the jetting pipe 17 is fixedly connected to one side of the discharge hopper 2. A one-way valve 18 is fixedly installed on the surface of the air inlet pipe 16, and a one-way pressure valve 19 is fixedly installed on the surface of the jetting pipe 17.

[0039] In this embodiment, by setting up an air jet mechanism, it is possible to reference the air jet while the extrusion plate 7 is reciprocating. Figure 3 , Figure 4 and Figure 5 When the extrusion plate 7 moves closer to the cam 6, it will drive the push rod 13, the push block 15 and the piston plate 20 to move closer to the cam 6. At this time, the gas collection box 14 is under negative pressure, and the gas can easily enter the gas collection box 14 through the air inlet pipe 16. When the extrusion plate 7 moves away from the cam 6, it will drive the push rod 13, the push block 15 and the piston plate 20 to move away from the cam 6. The piston plate 20 will squeeze the gas. When the gas pressure in the gas collection box 14 reaches the limit of the one-way pressure valve 19, the gas will be sprayed into the hopper 2 through the jet pipe 17, blowing off the material adhering in the hopper 2.

[0040] It should be noted that the one-way valve 18 is a valve that can only allow air to enter the air collection box 14, and the one-way pressure valve 19 is a valve that can only exhaust air from the air collection box 14.

[0041] A piston plate 20 is fixedly connected to one side of the push block 15. The piston plate 20 is made of rubber.

[0042] In this embodiment, by setting the piston plate 20, a sealed cavity can be formed inside the air collection box 14, so as to complete the steps of air collection and air jetting, thereby improving the sealing effect.

[0043] Working principle: During packaging, motor 5 is started, which drives cam 6 to rotate. (Refer to...) Figure 4 When the cam 6 rotates, its protruding end contacts the extrusion plate 7, which pushes the extrusion plate 7 to move away from the cam 6. At the same time, it drives the transmission rod 8, the linkage plate 10 and the striking rod 11 to move, and it also compresses the spring 12. When the cam 6 rotates to the point where it is no longer in contact with the extrusion plate 7, the elastic force generated by the spring 12 will push the extrusion plate 7 to reset suddenly. At the same time, it drives the transmission rod 8, the linkage plate 10 and the striking rod 11 to reset suddenly. The striking rod 11 will strike the buffer plate 22 to generate vibration, which is then transmitted to the hopper 2 to shake off the material adhering to its inner wall, thereby improving the packaging effect.

[0044] As the extrusion plate 7 reciprocates, reference Figure 3 , Figure 4 and Figure 5 When the extrusion plate 7 moves closer to the cam 6, it will drive the push rod 13, the push block 15 and the piston plate 20 to move closer to the cam 6. At this time, the gas collection box 14 is under negative pressure, and the gas can easily enter the gas collection box 14 through the air inlet pipe 16. When the extrusion plate 7 moves away from the cam 6, it will drive the push rod 13, the push block 15 and the piston plate 20 to move away from the cam 6. The piston plate 20 will squeeze the gas. When the gas pressure in the gas collection box 14 reaches the limit of the one-way pressure valve 19, the gas will be sprayed into the hopper 2 through the jet pipe 17, blowing off the material adhering in the hopper 2.

[0045] It should be noted that the motor 5 is a device or equipment existing in the prior art, or a device or equipment that can be implemented by the prior art, and the specific composition and principle of the power supply of the motor 5 are clear to those skilled in the art, so they will not be described in detail.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
