[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Example

[0019] See also Figure 1-2 The present invention provides an automatic diaper compression packaging machine, comprising a conveyor belt 1, a receiving plate 2, a clamping plate 3, a linear motor 4, a material removal rod 5, a material pushing electric cylinder 6 and a pushing plate 7. The conveyor belts 1 are arranged in pairs one above and one below for conveying unfolded diapers. The left ends of the paired conveyor belts 1 are aligned and the length of the upper conveyor belt 1 is shorter than the length of the lower conveyor belt 1.

[0020] The receiving plate 2 is located at the left end of the conveyor belt 1 . The top surface of the receiving plate 2 is concave to form a groove 201 for accommodating diapers, and a light sensor 202 is arranged in the groove 201 .

[0021] The splints 3 are arranged in pairs on the left and right sides between the gaps between the receiving plate 2 and the conveyor belt 1. The length direction of the splints 3 is parallel to the vertical direction. The top ends of the splints 3 are bent outward in an arc shape. A transducer 301 with an ultrasonic vibration device is embedded in the splints 3. The splints 3 are connected to the fixed plate 303 through springs 302. The fixed plate 303 is fixedly arranged under the conveyor belt 1 and the receiving plate 2.

[0022] A magnetic baffle 401 is arranged on the mover of the linear motor 4. The magnetic baffle 401 can slide on the mover of the linear motor 4 to form a moving pair with the mover of the linear motor 4, and adjacent magnetic baffles 401 repel each other. Push plate electric cylinders 402 are respectively installed at both ends of the linear motor 4. The movable end of the push plate electric cylinder 402 can push the magnetic baffle 401 to move. One end of the material shifting rod 5 is located between the clamping plates 3. The middle part of the material shifting rod 5 is connected to the rotating shaft of the material shifting motor 501. The material shifting motor 501 is located on one side of the clamping plate 3. The movable end of the material shifting cylinder 6 is connected to several push rods 601. When the mover of the linear motor 4 moves to the material shifting cylinder 6, the movable end of the material shifting cylinder 6 moves outward, which can drive the push rod 601 to push the diaper located between the magnetic baffles 401. The push plate 7 is vertically arranged between the adjacent clamping plates 3. The push plate 7 is fixedly connected to the movable end of the material pushing cylinder 701, and the material pushing cylinder 701 is fixedly arranged above the clamping plate.

[0023] The magnetic partition 401 refers to a plate-like component containing magnetic material or mainly made of magnetic material, which is used to divide and squeeze diapers. Magnetic materials belong to the prior art content and are known to those skilled in the art. The use of magnetic materials with different compositions will not have a substantial impact on the technical effect. Therefore, the specific composition and action mechanism of the magnetic material will not be further explained.

[0024] The control method of the present invention is to achieve automatic control through an external controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0025] Working principle: the unfolded diapers are placed on the conveyor belt 1 at the bottom for transportation. During the process, the paired conveyor belts 1 can squeeze the diapers during the transmission process to make the diapers flat. When the diapers are transported to the left end of the conveyor belt 1, the diapers will be located in the groove 201 of the receiving plate 2 and cover the light sensor 202. The light of the light sensor 202 is blocked and a signal will be generated to the external controller. The external controller controls the material-dispensing motor 501 to rotate so that the material-dispensing rod 5 will dial the diapers into the gap of the clamping plate 3. It can be suitable for diapers of different widths and lengths. The material-dispensing rod 5 that completes the dialing action is reset to a vertical state and will not affect the subsequent movement of the push plate 7.

[0026] Then the material-lifting electric cylinder 701 extends the push plate 7 into the gap of the clamping plate 3. During the process, the diaper will be folded and squeezed by the clamping plate 3. The clamping plate 3 is connected to the transducer 301 to generate ultrasonic vibration, which prompts the diaper to be folded. Then the material-lifting electric cylinder 701 resets the clamping plate 3 and repeats the above action to continue folding the diaper.

[0027] The diaper is pushed by the push plate 7 to leave the gap at the bottom of the clamping plate 3 and fall into the gap of the magnetic partition 401. During the process, the mover of the linear motor 4 can move so that folded diapers are placed between adjacent magnetic partitions 401. Then, the movable end of the electric cylinder 402 of the push plate 7 moves to bring the magnetic partitions 401 closer to each other to complete the extrusion and shaping of the diaper.

[0028] After shaping is completed, the linear motor 4 moves to the push cylinder 6. After the push plate 7 cylinder 402 is reset, the magnetic partition 401 will be reset due to magnetic repulsion. Then the moving end of the push cylinder 6 moves to make the push rod 601 push the diaper out of the gap of the magnetic partition 401.

[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
