Description

Technical Field

[0001] This utility model relates to the field of vacuum packaging equipment technology, specifically to an automatic impurity filtering device for vacuum packaging of metal coating. Background Technology

[0002] After production, the metal coating needs to be transferred to a vacuum packaging machine via a transfer rack for vacuum packaging, which facilitates subsequent storage and transportation.

[0003] Existing vacuum packaging uses negative pressure suction. During the negative pressure suction process, impurities in the air accumulate on the filter screen inside the packaging machine. Existing equipment only cleans and replaces the filter screen after it has been working for a period of time and its performance has significantly decreased. Moreover, the cleaning process requires the machine to be stopped and operated manually, which is time-consuming and labor-intensive.

[0004] In view of this, we propose an automatic impurity filtration device for vacuum packaging of metal coating. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: An automatic filtration device for vacuum packaging of metal coating includes a body, on which grippers are rotatably mounted. A vacuum seat is fixedly connected to the grippers, and a filter screen is disposed inside the vacuum seat. A negative pressure suction tube is fixedly connected between the vacuum seat and the body. A cleaning mechanism is provided on the vacuum seat for self-cleaning the filter screen.

[0007] Preferably, the vacuum seat has a negative pressure chamber inside, which is fixedly connected to the filter screen. A negative pressure port is provided on one side of the vacuum seat, and the negative pressure suction tube is connected to the negative pressure chamber.

[0008] Preferably, the cleaning mechanism includes a movable seat, which is fixedly installed on a vacuum seat. A branch pipe is fixedly connected between the movable seat and the negative pressure suction tube, and a piston rod is slidably installed inside the movable seat.

[0009] Preferably, a brush rod is fixedly installed on the bottom end of the piston rod surface, and the brush rod is provided with bristles, which are in contact with the filter screen.

[0010] Preferably, the bottom end of the brush rod is equipped with multiple connecting rods, and the bottom end of each connecting rod is fixedly connected to a sealing seat, which is slidably connected to the vacuum seat.

[0012] Preferably, the plurality of connecting rods are arranged in an array, and the plurality of limiting rods are arranged in an array.

[0013] By employing the above technical solution, this utility model provides an automatic impurity filtration device for vacuum packaging of metal coating, which has at least the following beneficial effects: This invention incorporates a cleaning mechanism between the vacuum seat and the negative pressure suction tube. This mechanism ensures that the cleaning process does not affect the vacuuming of the packaging while the vacuum seat is in operation.

[0016] 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.

[0017] Please see Figures 1-5An automatic impurity filtering device for vacuum packaging of metal coating includes a body 1, which contains a vacuum pump, pipelines, and other components to create a vacuum. Two grippers 2 are rotatably mounted on the body 1 and are arranged opposite each other. A vacuum seat 3 is fixedly connected to each gripper 2. The two symmetrical grippers 2 stably hold and fix the vacuum seat 3. The rotatable connection between the grippers 2 and the body 1 allows control of the angle of the vacuum seat 3, thereby improving its applicability.

[0018] Please see Figure 3 The vacuum seat 3 is provided with a negative pressure chamber 31, and a filter screen 33 is fixedly installed in the negative pressure chamber 31. A negative pressure port 32 is opened on one side of the vacuum seat 3. The packaging bag to be packaged can be fixed through the negative pressure port 32. The operation of the machine body 1 causes negative pressure to be generated in the negative pressure chamber 31, thereby removing the air in the packaging and realizing the vacuum packaging of the metal coating.

[0019] Please see Figure 1 A negative pressure suction tube 4 is fixedly connected between the vacuum seat 3 and the machine body 1. The negative pressure suction tube 4 enables the vacuum seat 3 to generate negative pressure suction, thereby vacuuming the packaging. A mounting frame 5 is fixedly installed on the machine body 1. The mounting frame 5 has an L-shaped structure, allowing it to be securely installed on the machine body 1 and providing a platform for mounting working components. Cylinders 6 are symmetrically mounted on both sides of the mounting frame 5. A square block is fixedly installed at the output end of each cylinder 6. The directional block is slidably connected to the mounting frame 5 via a rod. The negative pressure suction tube 4 is fixed to the mounting frame 5 and the square block, serving to organize the suction. Furthermore, the position of the square block can be adjusted by the cylinders 6 to match the angle of the vacuum seat 3, preventing unstable suction from the negative pressure suction tube 4. The negative pressure suction tube 4 is connected to the vacuum seat 3, providing pressure to the vacuum seat 3 and thus vacuuming the packaging.

[0020] Please see Figure 2 A cleaning mechanism 7 is provided between the vacuum seat 3 and the negative pressure suction tube 4 to automatically clean the filter screen 33. The cleaning mechanism 7 includes a movable seat 72, which is fixedly installed on the vacuum seat 3 and communicates with the negative pressure chamber 31. There are two movable seats 72, which are arranged relative to the vacuum seat 3. The movable seats 72 are connected to the negative pressure suction tube 4 through a branch tube 71.

[0021] Please see Figure 3 and Figure 4A piston rod 73 is slidably installed inside the movable seat 72. When the movable seat 72 is compressed through the branch pipe 71, a negative pressure is generated in the movable seat 72. Under this negative pressure, the piston rod 73 moves upward along the movable seat 72. A brush rod 74 is fixedly installed near the bottom of the piston rod 73. The brush rod 74 is equipped with bristles that contact the filter screen 33. The bristles clean the filter screen 33. The brush rod 74 moves with the piston rod 73, and the displacement of the piston rod 73 is controlled by the negative pressure, thus allowing the position of the brush rod 74 to be controlled by the negative pressure.

[0022] Please see Figure 4 Multiple connecting rods 75 are mounted at the bottom of the brush rod 74. A sealing seat 76 is fixedly connected to the bottom of each connecting rod 75. The connecting rods 75 are arranged in an array, serving to fix the brush rod 74 and the sealing seat 76 together, so that the displacement of the brush rod 74 will cause the sealing seat 76 to move as well. The sealing seat 76 is slidably connected to the vacuum seat 3. The sealing seat 76 has a T-shaped structure, and a sealing strip is provided at the contact point between the sealing seat 76 and the vacuum seat 3. This ensures a good sealing effect when the sealing seat 76 contacts the vacuum seat 3, without affecting the vacuum suction of the packaging.

[0023] In addition, multiple limiting rods 77 are fixedly installed inside the negative pressure chamber 31. Each limiting rod 77 corresponds to a connecting rod 75, and the limiting rods 77 are slidably connected to the brush rod 74. The limiting rods 77 make the displacement of the brush rod 74 more stable.

[0024] An automatic impurity filtration device for vacuum packaging of metal coatings, the working principle of which is as follows: When the packaging machine is working, the machine body 1 generates negative pressure. The negative pressure suction tube 4 draws suction from the inside of the movable seat 72 through the branch tube 71, creating negative pressure inside the movable seat 72. Under the action of negative pressure, the piston rod 73 moves upward along the movable seat 72. The displacement of the piston rod 73 drives the brush rod 74 to move. When the brush rod 74 moves, it drives the sealing seat 76 to move through the connecting rod 75, thus making the sealing seat 76 contact the vacuum seat 3. This ensures that the negative pressure chamber 31 has no other openings except for the negative pressure port 32, thus not affecting the vacuuming of the packaging. By drawing suction from the vacuum seat 3 through the negative pressure suction tube 4, the metal-coated packaging can be vacuumed.

[0025] After the vacuuming is completed, the negative pressure in the machine body 1 no longer exists and disappears. The negative pressure in the movable seat 72 disappears simultaneously. Under the action of gravity, the sealing seat 76, connecting rod 75 and brush rod 74 move down simultaneously, creating a gap in the vacuum seat 3. When the brush rod 74 moves down, it brushes away the dust and other impurities on the filter screen 33, and the impurities are discharged along the gap.
