DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figure 1-4 An automated mechanical packaging machine includes a base 1 and a conveyor belt 2 installed on the base 1, the conveyor belt 2 is arranged on one side of the base 1, and the masks are transported on the conveyor belt 2 in sequence after being formed. A trapezoidal block 6 arranged in an isosceles trapezoid is fixedly connected to the base 1, so that the two toggle rods 3 are limited by the trapezoidal block 6 and move away from each other and stretch the first spring 4, so that the two toggle rods 3 slide from one side of the magnetic block 32, and a third spring 18 is fixedly connected between the base 1 and the moving block 16.

[0020] One end of the base 1 away from the conveyor belt 2 is fixedly connected to a mounting cavity 8, and a pressing component is installed on the mounting cavity 8, and the pressing component includes a telescopic cavity 9, a lower plate 25, a fifth spring 26, a pressing plate 27, a clamping plate 30, and a limiting plate 7. The upper end of the telescopic cavity 9 is fixedly connected to the mounting cavity 8, and the lower plate 25 is fixedly connected to the lower end of the telescopic cavity 9. The pressing plate 27 is fixedly connected to the lower plate 25 through the fifth spring 26. A second spring 10 is fixedly connected between the lower plate 25 and the upper end of the telescopic cavity 9. As the lower plate 25 moves downward and pushes the pressing plate 27 to squeeze the mask, the elastic force of the fifth spring 26 is used to squeeze the mask. The two limiting plates 7 are fixedly connected to the mounting cavity 8, and the two clamping plates 30 are respectively slidably connected to the limiting plates 7. The lower end of the limiting plate 7 is arranged with an inclined surface. When the two clamping plates 30 move downward, they slide on the inclined surface on the limiting plate 7, so that the two clamping plates 30 can move in the center.

[0021] The pressing component also includes a fourth spring 22, a sleeve 23, a sliding rod 24, a push plate 28, and a threaded rod 29. Multiple sleeves 23 are respectively fixedly connected at the four corners of the lower plate 25, and multiple sliding rods 24 are respectively slidably connected in the sleeve 23, and one end of the sliding rod 24 is fixedly connected to the clamping plate 30. The fourth spring 22 is fixedly connected between the sleeve 23 and the clamping plate 30. When the two clamping plates 30 move in the center, the sliding rod 24 is pushed to slide in the sleeve 23 and squeeze the fourth spring 22. The two threaded rods 29 are rotatably connected between the two limit plates 7. Slide grooves are respectively provided at both ends of the two clamping plates 30, and teeth are provided in the slide grooves. The threaded rod 29 is meshed with the slide grooves, and the two push plates 28 are respectively fixedly connected to the threaded rod 29. Therefore, when the clamping plate 30 moves up and down, the meshed threaded rod 29 can be driven to rotate forward and reverse.

[0022] A conveying component is installed on the base 1, and the conveying component includes a rotating rod 19, a roller 5, a toggle rod 3, and a first spring 4. The rotating rod 19 passes through the base 1 horizontally, and the roller 5 is fixedly connected to the rotating rod 19. The multiple toggle rods 3 are divided into two groups, and each group of toggle rods 3 has two numbers. The two groups of toggle rods 3 are respectively slidably connected to both sides of the roller 5, and a first spring 4 is fixedly connected between the two toggle rods 3. As the roller 5 rotates, the toggle rods 3 on both sides can transport the masks conveyed on the conveyor belt 2 to the L-shaped plate 17 in sequence and stack them together.

[0023] The conveying component also includes an L-shaped plate 17, a magnetic block 32, a moving block 16, an inductor 20, and an electromagnetic plate 21. A transverse plate 12 is slidably connected to the base 1. The transverse plate 12 is used for the sliding of the L-shaped rod 17 and the placement of the mask. The L-shaped plate 17 is slidably connected to the transverse plate 12. The L-shaped plate 17 can push the mask to the other side of the transverse plate 12. When the L-shaped rod 17 is reset, it cannot drive the mask to reset. The two magnetic blocks 32 are respectively fixedly connected to the two sides of the L-shaped plate 17, the two moving blocks 16 are respectively slidably connected to the two sides of the base 1, the two inductors 20 are respectively fixedly connected to the rotating rod 19, and the electromagnetic plate 21 is fixedly connected to the inductor 20 (the inductor 20 can sense the number of rotations, so it can accurately stack the number of masks. When the set value is reached, the electromagnetic plate 21 can be energized and the electromagnetic plate 21 has magnetism. The inductor 20 is a prior art and will not be explained in detail here).

[0024] A square plate is provided on the base 1, and a sealed chamber 14 is fixedly connected to the square plate. A rotating shaft 13 is rotatably connected in the sealed chamber 14. One end of the rotating shaft 13 away from the sealed chamber 14 is rotatably connected to the mounting chamber 8. A piston 31 is slidably connected in the mounting chamber 8. A thread pattern is provided at one end of the rotating shaft 13, and the rotating shaft 13 is threadedly connected to the piston 31. An air delivery pipe 11 is fixedly connected between the sealed chamber 14 and the telescopic chamber 9. A tooth pattern is provided at the other end of the rotating shaft 13. A rack plate 15 is fixedly connected to one of the moving blocks 16, and the rack plate 15 is meshingly connected to the rotating shaft 13.

[0025] In the present invention, when in use, the processed masks are first moved from the left side to the right side of the conveyor belt 2 in sequence. As the conveyor belt 2 rotates, the masks are transported to the two toggle rods 3. Since one end of the rotating rod 19 is connected to an external servo motor, the rotating rod 19 is driven to rotate by the external servo motor. Since the roller 5 is fixed on the rotating rod 19, the toggle rod 3 rotates in a circular motion with the rotation of the roller 5, and the mask is rotated to fall on the L-shaped plate 17 on the right side. At the same time, the two toggle rods 3 are limited by the trapezoidal block 6 and are respectively opposite to each other. The two toggle rods 3 move away from each other and stretch the first spring 4, so that the two toggle rods 3 slide past one side of the magnetic block 32. When a certain number of masks are stacked on the L-shaped plate 17, the sensor 20 will sense the number of rotations and connect the electromagnetic plate 21 to a power source and energize it to have magnetism, thereby pushing the moving block 16 to move right with the rotation. Since the moving block 16 is a magnet, when the moving block 16 moves to the right, it attracts and drives the L-shaped plate 17 and the magnetic block 32 to move to the right, so that the L-shaped plate 17 pushes the mask to move right to the lower side of the pressing plate 27.

[0026] When the electromagnetic plate 21 moves away from the moving block 16 as the sensor 20 rotates, the sensor 20 cuts off the power to the electromagnetic plate 21. At this time, the moving block 16 moves to the left for reset under the pulling force of the third spring 18, thereby driving the L-shaped plate 17 to move to the left for reset. As a result, when the number of rotations of the sensor 20 and the number of stacked masks reach a certain number, the moving block 16 is pushed to move to the right, thereby achieving the function of conveying the stacked masks and achieving the reciprocating movement of the rack plate 15.

[0027] When the rack plate 15 moves to the right, it can drive the shaft 13 to rotate. When the shaft 13 rotates counterclockwise, the piston 31 wants to move away from the installation chamber 8 under the rotation of the shaft 13 and squeeze out the gas in the sealing chamber 14. At this time, the telescopic chamber 9 contracts under the pulling force of the second spring 10 and pulls the pressing plate 27 to move upward. When the rack plate 15 moves to the left, it drives the shaft 13 to rotate clockwise. At this time, the piston 31 moves toward one end close to the installation chamber 8 and squeezes the gas in the sealing chamber 14, so that the gas in the sealing chamber 14 is transported to the telescopic chamber 9 through the gas supply pipe 11. The telescopic chamber 9 is extended due to the increase of gas, and pushes the lower plate 25 and the pressing plate 27 to move downward. During the downward movement of 7, the two clamping plates 30 can be limited by the inclined surface of the limiting plate 7 and move in the center as the lower plate 25 moves downward, and the fourth spring 22 is compressed. As the two clamping plates 30 move in the center, the stacked masks can be squeezed and arranged in the center. At the same time, when the two clamping plates 30 move downward, the threaded rod 29 on the left side can be driven to rotate counterclockwise, while the threaded rod 29 on the right side can be driven to rotate clockwise. As the threaded rod 29 rotates, the push plate 28 can be driven to rotate 180°, and the stacked masks can be squeezed and arranged on the sides. Then, as the pressing plate 27 moves downward, it has a clamping effect on the arranged masks, thereby preventing multiple masks from being stacked on some relatively fluffy ones and affecting the packaging efficiency.

[0028] When the telescopic cavity 9 moves upward, the downward plate 25 is pulled and the pressing plate 27 is moved upward, and the two clamping plates 30 are no longer limited by the limiting plate 7. At this time, the two clamping plates 30 move away from each other under the elastic force of the fourth spring 22 and no longer have a clamping effect on the stacked masks. At the same time, the threaded rods 29 rotate in opposite directions, and the push plates 28 no longer clamp the masks.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
