[0026] Example

[0027] Reference Figure 1-Figure 5 The utility model provides a technical solution: a screening plate for a packaging machine, comprising a rectangular plate 1 and a distance adjusting mechanism 3, the upper surface of the rectangular plate 1 is fixedly connected to the partition 2, the distance adjusting mechanism 3 comprises a discharge hole 31, the discharge hole 31 is opened on the upper surface of the rectangular plate 1 and the side of the partition 2, the discharge hole 31 passes through the inside of the rectangular plate 1 and the partition 2 respectively, one side of a rotating plate 32 is rotatably installed on one side of the partition 2, an arc hole 321 is opened at one end of the rotating plate 32, a magnet 33 is embedded in the inside of the rectangular plate 1, an iron plate 331 is fixedly installed on one side of the rotating plate 32, and the position of the iron plate 331 corresponds to that of the magnet 33.

[0028] In a preferred embodiment, a baffle 4 is fixedly installed on the periphery of the upper surface of the rectangular plate 1, and a through hole 5 is opened on the upper surface of the rectangular plate 1. The through holes 5 are arranged in a plurality and are evenly arranged on the upper surface of the rectangular plate 1. When the raw materials are transported to the rectangular plate 1, in order to prevent the raw materials from being scattered from the rectangular plate 1, a baffle 4 is installed on the rectangular plate 1, and the partition 2 is wrapped in the space enclosed by the baffle 4, so as to prevent the raw materials from being scattered from the rectangular plate 1 and causing waste.

[0029] In a preferred embodiment, a plurality of partitions 2 are provided and are evenly arranged on the upper surface of the rectangular plate 1. A rotating plate 32 is rotatably installed on the left and right sides of each partition 2. An arc-shaped hole 321 is provided at one end of each rotating plate 32. In order to change the diameter of the sieve hole, the device rotatably installs a rotating plate 32 on the partition 2, and an arc-shaped hole 321 is provided on the rotating plate 32. By rotating the rotating plates 32 on two adjacent partitions 2 and fitting the ends of the two rotating plates 32 together, the arc-shaped holes 321 can be combined into a circular hole, thereby changing the aperture of the sieve hole. The device is suitable for screening small particle raw materials and meets the requirements of use.

[0030] This device not only facilitates adjustment of the diameter of the sieve holes, but also can control the shaking of the rectangular plate 1 to improve the screening effect. A driving mechanism 6 is installed on the outside of the rectangular plate 1, and the driving mechanism 6 includes a conveyor belt 61, a motor 62 and a connecting rod 63. The outer surface of the rectangular plate 1 is rotatably connected to the connecting rod 63, and one end of the connecting rod 63 is rotatably connected to the driving rod 7. A conveyor belt 61 is arranged above the rectangular plate 1, and a round roller 8 is installed on the inner side of the conveyor belt 61. The two ends of the round roller 8 are respectively fixedly connected to the disc 9, and the driving rod 7 is fixedly installed on the outer surface of the disc 9. There are two round rollers 8, which are respectively arranged at the inner side of the conveyor belt 61, and one end of one of the round rollers 8 is fixedly connected to the driving wheel 10, which is meshed with the control wheel 11. The control wheel 11 is fixedly installed on the outer surface of the transmission shaft, and the transmission shaft is fixedly installed on the output end of the motor 62.

[0031] During operation, the motor 62 drives the control wheel 11 to rotate, and drives the driving wheel 10 to rotate, so that one of the round rollers 8 will rotate. The rotation of the round roller 8 will control the rotation of the conveyor belt 61, and the raw materials on the conveyor belt 61 will be transported to the rectangular plate 1. When the round roller 8 rotates, it will drive the disc 9 to rotate, and the driving rod 7 will follow the rotation of the disc 9, thereby driving the connecting rod 63 to move. The connecting rod 63 will drive the rectangular plate 1 to move up, down, left and right, thereby controlling the shaking of the rectangular plate 1, which is convenient for screening the raw materials on the rectangular plate 1.

[0032] Specifically, the working process or working principle of a screening plate for a packaging machine is as follows: when the packaging machine packages the granular raw materials, it will first screen the granular raw materials, leaving some large granular raw materials in the granular raw materials, and screen out the small granular raw materials, so as to facilitate the screening of the granular raw materials and obtain the required raw materials. However, in actual operation, the diameters of different granular raw materials are different. For some raw materials with smaller particle diameters, the raw materials will all fall on the screen plate and cannot be screened, thus affecting their use. Therefore, this device is designed to solve this problem.

[0033] The raw materials are conveyed to the rectangular plate 1 by using the conveyor belt 61, and the round roller 8 is driven to rotate by the motor 62, which causes the conveyor belt 61 to rotate on the round roller 8. One end of the rectangular plate 1 extends out of one end of the conveyor belt 61, which can ensure that the raw materials on the conveyor belt 61 are conveyed to the rectangular plate 1. The device sets the rectangular plate 1 to an inclined state. When the raw materials fall on the rectangular plate 1, they move toward one end on the rectangular plate 1 and pass through the inside of the discharge hole 31. During the movement, small particles of raw materials will fall through the through hole 5. A collection bin can be placed at the bottom of the rectangular plate 1, and the fallen particles of raw materials will fall into the inside of the collection bin.

[0034] The control wheel 11 is driven to rotate by the motor 62, and the control wheel 11 drives the driving wheel 10 to rotate, thereby controlling the rotation of the round roller 8. In this device, a disc 9 is installed at the end of each round roller 8, and a driving rod 7 is fixedly installed on the disc 9. The driving rod 7 is rotatably connected with the connecting rod 63. When the disc 9 rotates with the round roller 8, the driving rod 7 is driven to move, thereby driving the connecting rod 63 to move. The rotatable connection between the connecting rod 63 and the rectangular plate 1 will move the rectangular plate 1 up, down, left and right, causing the rectangular plate 1 to shake, thereby accelerating the screening effect of the raw material on the rectangular plate 1 to meet the use requirements.

[0035] This device can change the diameter of the screening hole on the rectangular plate 1, and rotate the rotating plate 32 to expand or store it according to the diameter of the particle raw material. When the particle diameter is large, the rotating plate 32 can be stored and the raw material can be screened using the through hole 5. When the particle diameter is small, in order to prevent all the raw materials from being discharged through the through hole 5, the rotating plate 32 can be rotated at this time, and the rotating plate 32 can be laid flat on the upper surface of the rectangular plate 1, and the rotating plates 32 on the two adjacent partitions 2 are rotated, so that the arc holes 321 on the two rotating plates 32 are combined into a circular hole, and the diameter of the circular hole is smaller than the diameter of the through hole 5. At this time, raw materials with small particle diameters can be screened, and all raw materials are prevented from falling through the through hole 5, which is convenient for screening raw materials with different diameters.

[0036] To ensure that the device can be used stably, the device will be installed on the support frame 12, the round roller 8 is rotatably connected to the support frame 12, and the conveyor belt 61 is set at the inner side of the support frame 12 to limit the conveyor belt 61 and facilitate the transportation of raw materials. At the same time, the vertical plate 13 is fixedly installed on the support frame 12, and the vertical plate 13 is fixedly connected to the motor 62, so that the motor 62 can work stably and drive the conveyor belt 61 to rotate to meet the use requirements.

[0037] It should be noted that the motor 62 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they are not described in detail.
