Description

Technical Field

[0001] This utility model relates to the field of packaging equipment, and in particular to a powder vacuuming mechanism. Background Technology

[0002] Packaging machines are machines that use packaging bags to package products, serving both a protective and aesthetic purpose.

[0003] Vacuum packaging machines are a type of packaging machine that can vacuum-seal and then repackage products. Patent application number 2020104858110 discloses a dual-station vacuum forming box. This vacuum packaging equipment is effective for packaging granular materials, but its effectiveness for powdered materials is only average. The main reasons are as follows: the vacuum forming box uses a vacuuming mechanism, which generates excessive suction force that is difficult to adjust. This causes the powder to easily rise during vacuuming, resulting in an insecure seal when it reaches the bag opening.

[0046] This utility model discloses a powder vacuuming mechanism, which consists of a vacuuming subunit 1 composed of a vacuuming tube 11, a flow control switch 12, and a solenoid valve 13. The vacuuming subunit 1 is started in stages, that is, vacuuming at low speed first and then at high speed, which can minimize the upward movement of powder and solve the problems existing in the prior art.

[0047] The technical solutions of the present utility model will be clearly and thoroughly described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Please refer to... Figures 1 to 5 The powder vacuuming mechanism provided by this utility model is used in a packaging machine. The packaging machine is provided with a horizontal sealing mechanism and a vacuum shaping mechanism from top to bottom, including: at least two vacuuming sub-units 1. The vacuuming sub-unit 1 includes a vacuuming tube 11, a flow control switch 12 and a solenoid valve 13.

[0048] The air inlet 131 of the solenoid valve 13 is connected to the flow control switch 12, and the flow control switch 12 is connected to the vacuum shaping mechanism through the vacuum tube 11.

[0049] The suction end 132 of the solenoid valve 13 is connected to the vacuum pump;

[0050] After the vacuum pump is started, air enters the vacuum pump from the vacuum shaping mechanism through the vacuum tube 11, the flow control switch 12, the air inlet 131 and the air intake 132.

[0051] In this invention, after the material enters the packaging bag, the horizontal sealing mechanism horizontally seals the bag. Then, the horizontal sealing cutter cuts the sealed area into two parts: one part serves as the top horizontal seal of the lower packaging bag, and the other part serves as the bottom horizontal seal of the upper packaging bag. The horizontally sealed packaging bag directly enters the vacuum shaping mechanism, or is conveyed to the vacuum shaping mechanism by other mechanisms. The vacuum shaping mechanism performs vacuuming on the packaging bag containing the material. Specifically, taking a powder vacuuming mechanism comprising two vacuuming sub-units 1 as an example, one vacuuming sub-unit 1 is first activated to perform vacuuming, and this vacuuming sub-unit 1 is adjusted to a suitable suction force through the flow control switch 12. After 30% to 50% of the air remains in the packaging bag, the remaining vacuuming sub-unit 1 is activated and adjusted to the maximum suction force for full-speed vacuuming. Because the initial vacuuming force is relatively small, the powder will not easily rise. When the vacuuming reaches a certain level, the packaging bag above the material is relatively close, and even with a large suction force, the powder will not easily rise. Therefore, this solves the problems existing in the prior art.

[0052] Preferred,

[0053] The vacuum pumping subunit 1 includes at least two vacuum pumping tubes 11.

[0054] The vacuum pumping subunit 1 may include multiple vacuum pumping tubes 11, which are connected to different positions of the vacuum shaping mechanism, that is, to perform vacuuming at different positions.

[0055] Preferred,

[0056] Two vacuum pumping subunits 1;

[0057] The vacuum pumping subunit 1 includes two vacuum pumping tubes 11, and the suction end 132 of the solenoid valve 13 is connected to the vacuum pump through the suction pipe 14.

[0058] Preferred,

[0059] The horizontal sealing mechanism includes a first horizontal sealing block 21 and a second horizontal sealing block 22 arranged opposite to each other;

[0060] The first horizontal sealing block 21 is divided into a first upper sealing part 211 for sealing the bottom of the packaging bag and a first lower sealing part 212 for sealing the top of the packaging bag, with the first horizontal sealing cutter as the boundary. The first lower sealing part 212 is provided with a first vacuum groove 2121, and the inlet and outlet of the first vacuum groove 2121 are not on the same vertical line.

[0061] The first horizontal sealing block 21 and the second horizontal sealing block 22 cooperate with each other.

[0062] Preferred,

[0063] The first vacuum tank 2121 has a Z-shaped structure.

[0064] It should be noted that the first vacuum tank 2121 is designed to provide a vacuuming channel, allowing the packaging bag to be vacuumed after the vacuum shaping mechanism is in place. Furthermore, because the inlet and outlet are not on the same vertical line, it can block the powder from being thrown up, ensuring that the powder remains at the lower end of the first vacuum tank 2121.

[0065] Preferred,

[0066] The vacuum shaping mechanism is equipped with a vacuum sealing unit 31;

[0067] The vacuum sealing unit 31 includes a first sealing block 311 and a second sealing block 312 disposed opposite to each other;

[0068] A first pressing block 313 is provided below the first sealing block 311, and a second vacuum groove 3131 is provided on the first pressing block 313;

[0069] A second pressing block 314 is provided below the second sealing block 312, and the second pressing block 314 is provided with a groove that cooperates with the second vacuum groove 3131.

[0070] The first sealing block 311 and the second sealing block 312 work together to seal the top of the packaging bag;

[0071] The first pressing block 313 and the second pressing block 314 clamp the top of the packaging bag.

[0072] Preferred,

[0073] The second vacuum tank 3131 is a vertical tank.

[0074] In this invention, the first pressing block 313 and the second pressing block 314 cooperate to press down the upper part of the packaging bag, and a second vacuum groove 3131 is reserved for air flow. Generally, 3 to 6 second vacuum grooves 3131 can be set on the first pressing block 313. Since air can only flow through the second vacuum grooves 3131, the other parts of the first pressing block 313 block the powder, which can keep most of the powder in the packaging bag below the first pressing block 313. The cooperation of the first vacuum groove 2121 and the second vacuum groove 3131 can block most of the powder that is thrown up.

[0075] Preferred,

[0076] The packaging machine is provided from top to bottom with the horizontal sealing mechanism, the material distribution mechanism, and at least two vacuum shaping mechanisms;

[0077] The material distribution mechanism delivers material from the horizontal sealing mechanism to different vacuum shaping mechanisms.

[0078] Preferred,

[0079] A vibration mechanism is installed below the material distribution mechanism;

[0080] The vibration mechanism is located directly below the horizontal sealing mechanism;

[0081] The vibration mechanism includes a vibration plate 41 and a vibration cylinder 42. The vibration plate 41 is installed directly below the horizontal sealing mechanism, and the vibration cylinder 42 is connected to the vibration plate 41 and is used to drive the vibration plate 41 to reciprocate.

[0082] Preferred,

[0083] The vacuum shaping mechanism is mounted on the same mounting plate 001;

[0084] The vibration cylinder 42 is mounted on the mounting plate 001 via the cylinder mounting seat 43.

[0085] It should be noted that after the powder falls into the packaging bag, it is generally distributed in a cone shape at the top of the packaging bag. This is not only unsightly, but also not conducive to sealing. Therefore, the vibration mechanism composed of the vibrating plate 41 and the vibrating cylinder 42 can vibrate and shape the packaging bag, so that the powder distribution inside the packaging bag is more even.

[0086] The powder vacuuming mechanism provided by this utility model is used in a packaging machine. The packaging machine is equipped with a horizontal sealing mechanism and a vacuum shaping mechanism from top to bottom, including at least two vacuuming subunits 1. Each vacuuming subunit 1 includes a vacuuming tube 11, a flow control switch 12, and a solenoid valve 13. The inlet end 131 of the solenoid valve 13 is connected to the flow control switch 12, and the flow control switch 12 is connected to the vacuum shaping mechanism through the vacuuming tube 11. The suction end 132 of the solenoid valve 13 is connected to a vacuum pump. After the vacuum pump is started, air enters the vacuum pump from the vacuum shaping mechanism through the vacuuming tube 11, the flow control switch 12, the inlet end 131, and the suction end 132. Through the vacuuming subunit 1 composed of the vacuuming tube 11, the flow control switch 12, and the solenoid valve 13, the powder vacuuming mechanism of this utility model adopts a segmented start-up method for the vacuuming subunit 1, that is, low-speed vacuuming followed by high-speed vacuuming, which can minimize the upward movement of powder and solve the problems existing in the prior art.

[0087] The powder vacuuming mechanism provided by this utility model has been described in detail above. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the ideas of the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
