[0032] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0033] In the description of the present invention, reference is made to Figure 1 It should be noted that in the field of interventional feeding instruments, the feeding direction refers to the direction pointed by arrow A. The above definition is only for the convenience of expression and cannot be understood as a limitation of the present invention.

[0034] like Figure 1-7 As shown, in the embodiment of the feeding mechanism of the paging machine of the present invention, the feeding mechanism comprises: a suction component 2 and a feeding component 3;

[0035] Among them, the suction component 2 includes a suction nozzle 22, a clamping piece 23 and a fixed block 21. A ventilation cavity is provided in the fixed block 21. The lower part of the fixed block 21 is provided with a first air blowing pipe 24 and a second air blowing pipe 25 both connected to the ventilation cavity. The blowing port of the first air blowing pipe 24 is horizontally pointed in the feeding direction, and the blowing port of the second air blowing pipe 25 is inclined to the feeding direction. The suction nozzle 22 is detachably connected to the surface of the fixed block 21 facing the feeding direction. The clamping piece 23 is located on the side of the fixed block 21 and is used to press the surface of the material; the feeding component 3 is located in front of the suction component 2 and is used to transport the sucked material forward.

[0036] Combined with the structure described above, it can be known that the products to be paged are placed on the feeding device 1. At this time, the surface of the uppermost product is under the joint action of the first blowing pipe 24 and the second blowing pipe 25, and the clamping member 23 presses the two sides of the surface of the uppermost product, so that the middle part of the uppermost product is blown up and separated from the contact with the lower layer of products, and then the uppermost product is sucked up by the action of the suction nozzle 22, and finally the sucked product is conveyed forward by the feeding assembly 3. In this way, the products placed on the feeding device 1 are alternately paged, and the structure is simple, which reduces the labor intensity of workers and improves work efficiency.

[0037] In one embodiment, the first air blowing pipe 24 is fixedly connected to the lower surface of the fixed block 21, and the second air blowing pipe 25 is connected to the side of the lower part of the fixed block 21, and the angle between the second air blowing pipe 25 and the first air blowing pipe 24 is in the range of 10° to 30°. Because when the angle value is less than 10°, the blowing force of the air blowing pipe on the surface of the material is not enough, the floating effect is not good, which is not conducive to the subsequent suction of the suction nozzle 212; when the angle value is greater than 30°, the blowing force of the air blowing pipe on the surface of the material is too large, so that the material floats to a large extent, which is not conducive to the subsequent suction of the suction nozzle 22. In this embodiment, the angle between the second air blowing pipe 25 and the first air blowing pipe 24 is 20°.

[0038] In one embodiment, a connecting block 28 is further included, and the connecting block 28 is movably connected to the side of the lower part of the fixed block 21 through a hollow connecting column 29, the connecting column 29 is communicated with the ventilation cavity, and the air inlet of the second blowing pipe 25 extends into the connecting block 28 and communicates with the connecting column 29. The angle direction of the second blowing pipe 25 can be adjusted by adjusting the direction of the connecting block 28, so that the blowing direction can be adjusted accordingly according to different materials.

[0039] In one embodiment, a mounting block 26 is provided on the surface of the fixing block 21 facing the feeding direction, a protruding clamping block 27 is provided on the surface of the mounting block 26, and a clamping groove that cooperates with the clamping block 27 is provided on the suction nozzle 22. The connection between the clamping block and the clamping groove is convenient for installation or removal.

[0040] In one embodiment, the clamping member 23 includes a pressure strip 233, a mounting column 231 and a slider 232, one end of the mounting column 231 is fixedly connected to the side of the fixed block 21, the slider 232 is slidably connected to the mounting column 231, and one end of the pressure strip 233 is movably connected to the slider 232.

[0041] The pressure strip 233 includes a connecting section 2331 and a pressing section 2332. One end of the connecting section 2331 is movably connected to the slider 232, and the other end of the connecting section 2331 is connected to the pressing section 2332. An angle is formed between the pressing section 2332 and the connecting section 2331, and the value range of the angle is 120° to 150°. Because when the angle is too small, the pressure of the pressing member 23 on the product is not enough, and the product is easy to fall off; when the angle is too large, the pressure of the pressing member on the product is too large, and it is not easy to blow the product and be sucked by the nozzle. In this embodiment, the angle is 130°.

[0042] In one embodiment, the feeding assembly 3 includes a rotating shaft 33, a driving motor 31 and a roller 35. The rotating shaft 33 is located in front of the suction assembly 2. A driven wheel 34 is provided at one end of the rotating shaft 33. A driving wheel 32 is provided at the driving end of the driving motor 31. The driving wheel 32 is meshed with the driven wheel 34. The roller 35 is connected to the other end of the rotating shaft 33.

[0043] Specifically, a wear-resistant sleeve 36 is sleeved on the surface of the roller 35 , a plurality of waist-shaped holes 38 are formed on the wear-resistant sleeve 36 , and a plurality of small holes 37 corresponding to the waist-shaped holes 38 are formed on the surface of the roller 35 .

[0044] In one embodiment, in order to prevent the roller 35 from swinging left and right when the rotating shaft 33 drives the roller 35 to rotate, a limit block 39 is provided on the rotating shaft 33 , and the limit block 39 is located on the inner side of the roller 35 .

[0045] It can be understood that the above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, the above technical features can be freely combined without departing from the concept of the present invention, and several deformations and improvements can be made, which all belong to the protection scope of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should belong to the coverage of the claims of the present invention.
