[0002] like Figure 1 As shown, Figure 1 A is a booklet of some products, similar to a manual, used to introduce some products or some publicity. Often similar booklets, manuals, etc., need to insert some other thin pages A2 in the booklet.

[0003] The most traditional way is for people to manually open the first page A1, then put A2 in, and then close it. In order to increase efficiency, the packaging machines on the market will cooperate with the card issuing machine and the conveyor belt. The principle is that the first card issuing machine first conveys A to the conveyor belt, and then the conveyor belt conveys A to the output end of the second card issuing machine. At this time, the conveyor belt is paused, and the suction cup first absorbs A1 so that A1 is opened, and then the second card issuing machine conveys A2 between the opened A1 and A, and then the suction cup stops adsorption, A and A1 are closed, and the conveyor belt is transported for packaging. The overall structure improves efficiency compared to the traditional manual placement of A2, but the efficiency is still low and cannot meet production needs. Summary of the invention

The linear speed of the periphery of the suction page-opening wheel 41 is the same as the conveying speed of the conveying mechanism 1. The linear speed of the periphery of the suction page-opening wheel 41 is the same as the conveying speed of the conveying mechanism 1, which ensures that the suction page-opening wheel 41 has the same moving speed as the booklet 5 below when it continues to move along the first direction after sucking the top page of the booklet 5. If they are not the same, the top page of the booklet 5 will be creased, or even torn in severe cases.

[0051] The second card issuing mechanism 3 is also a prior art and will not be described in detail here. It is arranged near the end of the page opening rack 42 and is used to convey the stacked thin pages one by one to the booklet 5 conveyed on the conveying mechanism 1 and opened by the page opening rack 42. It should be noted that the thin pages are not only a single-layer page of paper, but can also be a thin booklet composed of multiple layers of pages.

[0052] The embodiment of the present invention provides a suction page-opening device, wherein the first card issuing mechanism 2 pages the booklet 5 one by one onto the conveying mechanism 1, and on the conveying mechanism 1, the conveying mechanism 1 continuously pushes the booklet 5 to move along the first direction, and when the booklet 5 moves to the bottom of the suction page-opening wheel 41, the suction page-opening wheel 41 starts to suck up the top page from a sharp corner of the booklet 5, and then the top page is placed on the page-opening frame 42 and continues to move along the first direction, as the booklet 5 is continuously conveyed one by one, the suction page-opening mechanism 4 continuously and continuously performs the steps of suction and page-opening one by one, and the second card issuing machine paginates the thin pages one by one onto the opened booklet 5, and when the booklet 5 continues to be conveyed one by one away from the page-opening frame 42, the booklet 5 is naturally closed under the action of gravity. The suction page-opening device provided by the present invention can continuously and uninterruptedly complete the steps of suction page-opening, and effectively improve the efficiency of page-opening.

[0053] In some embodiments, Figure 2 , 4 As shown in 5, the suction page-opening mechanism 4 also includes a first fixed frame 431, which is connected to the conveying mechanism 1, and a fixed box 432 is provided on the first fixed frame 431, and a page-opening shaft 433 is rotatably provided on the fixed box 432, one end of the page-opening shaft 433 is connected to a first follower wheel 436, and the other end of the page-opening shaft 433 is connected to the suction page-opening wheel 41, and a second fixed frame 438 is further provided on the side of the fixed box 432 away from the suction page-opening wheel 41, and a page-opening motor 434 is provided on the top of the second fixed frame 438, and a first driving wheel 435 is provided at the output end of the page-opening motor 434, and a first belt 437 is sleeved between the first driving wheel 435 and the first follower wheel 436, and the page-opening motor 434 drives the suction page-opening wheel 41 to rotate, and when the booklet 5 moves to the bottom of the suction page-opening wheel 41, the suction page-opening wheel 41 sucks up a corner of the booklet 5. Specifically, in the embodiment of the present invention, in order to rotate the suction page-opening wheel 41, the page-opening motor 434 drives the first driving wheel 435 to rotate, and the first driving wheel 435 drives the first follower wheel 436 to rotate through the first belt 437, and the first follower wheel 436 and the page-opening shaft 433 are coaxially arranged, and the first follower wheel 436 drives the page-opening shaft 433 to rotate. Since the end of the page-opening shaft 433 is coaxially connected to the suction page-opening wheel 41, the suction page-opening wheel 41 rotates synchronously therewith.

[0054] In some embodiments, Figure 2 , 4 As shown in FIGS. 5, 6, 7, 8 and 9, a negative pressure wheel 44 is sleeved on the page opening shaft 433 between the suction page opening wheel 41 and the fixed box 432. The negative pressure wheel 44 is fixed and does not rotate with the page opening shaft 433. Figure 6As shown in (b), the negative pressure wheel 44 includes a first through hole 441 passing through the page opening shaft 433, and a plurality of first negative pressure holes 442 are provided on the side of the negative pressure wheel 44 away from the suction page opening wheel 41, and the first negative pressure holes 442 are connected to an external negative pressure device (not shown in the figure), and the negative pressure device refers to a device that can generate vacuum adsorption, and the negative pressure device can be a vacuum pump, etc., which is a prior art and is not repeated here; Figure 6 As shown in (a), the negative pressure wheel 44 is provided with a plurality of arcuate grooves 443 on one side facing the suction opening wheel 41, and the arcuate grooves 443 are in one-to-one communication with the first negative pressure holes 442. In order to fix the negative pressure wheel 44, a first fixing plate 451 is provided on the side of the fixing box 432 close to the negative pressure wheel 44, and a second fixing plate 452 is connected to the first fixing plate 451, and the second fixing plate 452 is connected to the negative pressure wheel 44. A fixing installation hole is also provided on the negative pressure wheel 44, and the fixing installation hole can be connected to the second fixing plate 452 by screw connection, so as to fix the negative pressure wheel 44. The plurality of first negative pressure holes 442 are arranged in a circular array with the axis of the negative pressure wheel 44 as the midpoint, and the plurality of arcuate grooves 443 are also arranged in a circular array with the axis of the negative pressure wheel 44 as the midpoint;

[0055] like Figure 7 As shown, a connecting hole 413 is provided in the middle of the suction opening wheel 41, and the connecting hole 413 is used to connect the opening shaft 433. The suction opening wheel 41 is provided with a plurality of first suction opening holes 411 on the side facing the negative pressure wheel 44, and the first suction opening holes 411 are surrounded by a circular ring. The first suction opening holes 411 are arranged in a circular array with the axis of the suction opening wheel 41 as the midpoint, and the first suction opening holes 411 can be communicated with the arc-shaped groove 443. A plurality of second suction opening holes 412 are provided on the side of the suction opening wheel 41, and the second suction opening holes 412 are communicated with the first suction opening holes 411 one-to-one. More preferably, the second suction opening holes 412 are a pair, and one first suction opening hole 411 corresponds to a pair of second suction opening holes 412. Figure 8 and 9As shown, a plurality of first ventilation ducts 415 and second ventilation ducts 416 are arranged inside the suction opening wheel 41, wherein one first suction opening hole 411 is connected to a first ventilation duct 415, and the second ventilation ducts 416 are also arranged in pairs, and the second ventilation ducts 416 correspond one-to-one to the second suction opening holes 412, the second ventilation duct 416 is connected to the second suction opening holes 412, and the first ventilation duct 415 is connected to the second ventilation duct 416. Specifically, the negative pressure device generates vacuum adsorption through the first negative pressure hole 442 connected to the arc groove 443, and through the arc groove 443 connected to the first suction page opening hole 411. It should be noted that the attached page wheel is infinitely close to the suction page opening wheel, but does not contact the suction page opening wheel; the first suction page opening hole 411 is connected to the first ventilation duct 415, the first ventilation duct 415 is connected to the second ventilation duct 416, and the second ventilation duct 416 is connected to the second suction page opening hole 412, thereby generating a vacuum adsorption force on the outer peripheral side of the suction page opening wheel 41. It should be further explained that the negative pressure device can be selectively connected to any one or more first negative pressure holes 442, and the corresponding arc groove 443 connected to the negative pressure device can produce vacuum adsorption. Similarly, only some first suction opening holes 411 corresponding to the arc groove 443 have vacuum adsorption, and similarly, only some corresponding second suction opening holes 412 have vacuum adsorption. The reason for this arrangement is to ensure that only the booklet 5 can be vacuum adsorbed during the 0.1 second to 0.5 second moment when it is under the suction opening wheel 41. Once this time has passed, the suction opening wheel 41 continues to rotate, and the second suction opening hole 412 that originally had vacuum adsorption no longer has vacuum adsorption, thereby preventing the top page of the booklet 5 from being adsorbed on the outer periphery of the suction opening wheel 41, causing damage to the booklet 5 and making it impossible to proceed to the next step.

The second fixed frame 438 is provided with a second strip hole 4381, and the second strip hole 4381 is used to connect the fixed box 432 and to adjust the position of the first driving wheel 435 along the third direction, so as to keep the first belt 437 taut.

[0057] In some embodiments, Figure 4 , 10 As shown in Figure 11, after the vacuum suction of the air suction opening wheel 41, in order to improve the efficiency of the air suction opening and connect the opening frame 42, the air suction opening mechanism 4 also includes an opening part 46, which is arranged below the air suction opening wheel 41. The opening part 46 includes an opening tip 461 and an opening tail 462. The opening tip 461 extends to the opening tail 462 in a cone shape, and the opening frame 42 is connected to the opening tail 462. Specifically, when the air suction opening wheel 41 sucks a corner of the booklet 5, the opening tip 461 is inserted from this corner to the opening tail 462 at the same time. Figure 1 As shown between A and A1, as the booklet 5 continues to move, the page opening portion 46 is inserted into the booklet 5, and the page opening tail 462 increases the page opening width. The booklet 5 continues to move to the page opening rack 42, and the page opening width is further increased by the page opening rack 42.

The position of the page-opening tip 461 along the first direction is adjusted through the sixth strip hole 4661, that is, to ensure that the page-opening tip 461 is inserted into the booklet 5 at the moment when the suction page-opening wheel 41 is adsorbed. It should also be noted that the page-opening connecting plate 463 is not only used to adjust the page-opening tip 461, but also needs to move the page-opening tip 461 away from the fourth fixed frame 464, the fifth fixed frame 465 and the sixth fixed frame 466. Otherwise, as the booklet 5 moves, the top page of the booklet 5 will be blocked by the fourth fixed frame 464 and the fifth fixed frame 465.

[0059] In some embodiments, Figure 2 and 4As shown, the page opening frame 42 includes a plurality of page opening support frames 421 and a page opening main frame 422, one end of the page opening support frame 421 is connected to the conveying structure, and the other end of the page opening support frame 421 is connected to the page opening main frame 422; the page opening main frame 422 includes a first section 4221, a second section 4222, a third section 4223 and a fourth section 4224, the first end is connected to the second section 4222, the second section 4222 is connected to the third section 4223, the third section 4223 is connected to the fourth section 4224, the first section 4221 extends along the first direction and the second direction, the second section 4222 extends along the first direction, the second direction and the third direction, the third section 4223 extends along the first direction and the second direction, and the fourth section 4224 extends along the first direction; the first direction, the second direction and the third direction are perpendicular to each other. Specifically, in the embodiment of the present invention, after the top page of the booklet 5 is sucked by the suction page-opening wheel 41 and opened by the page-opening tip 461, the top page of the booklet 5 is only slightly opened, and the opening amplitude is small. If the second card issuing mechanism 3 is to issue cards normally, the opening amplitude must be increased. As the booklet 5 is pushed by the conveying mechanism 1, the booklet 5 passes through the first section 4221, the second section 4222, the third section 4223 and the fourth section 4224, so that the opening amplitude of the booklet 5 is continuously increased, and the opening amplitude is the largest in the second section 4222, and the second issuing mechanism 3 issues cards one by one in the second section 4222. The top page of the booklet 5 first passes through the first section 4221 for a smooth transition and is opened in the first direction and the second direction in the first section 4221. The booklet 5 continues to enter the second section 4222 and is opened in the first direction, the second direction and the third direction in the second section 4222. It should be noted that the first section 4221 and the second section 4222 are coordinated as a whole. When the booklet 5 enters the second section 4222, the first section 4221 also supports the booklet 5. Otherwise, the booklet 5 will hinge in the second section 4222 due to lack of support at the back. The booklet 5 continues to enter the third section 4223 and is transported in the first direction and the second direction in the third section 4223. The third section 4223 connects the booklet 5 in the second section 4222 and the fourth section 4224. At the same time, the third section 4223 enables the second section 4222 to transition smoothly to the fourth section 4224. If the second section 4222 to the fourth section 4224 is directly transferred, a crease will be formed on the top surface of the booklet 5 due to too fast transition. In addition, the second section 4222 is closely corresponding to the fourth fixing frame 464, the fifth fixing frame 465, and the sixth fixing frame 466. The second section 4222 allows the booklet 5 to be opened in the third direction to reach the maximum in advance, thereby preventing the top opened page of the booklet 5 from being blocked by the sixth fixing frame 466. When the booklet 5 continues to move and passes the fourth section 4224, the top opened page of the booklet 5 is hinged under the action of gravity, and at this time, the second card issuing mechanism 3 has completed the sheet conveying clamp in the booklet 5.

[0060] In some embodiments, Figure 2 and 13 As shown, the conveying mechanism 1 includes a conveying drive mechanism 12 and a conveying frame 11. The conveying frame 11 is provided with a conveying channel 13, and the conveying channel 13 extends along a first direction. The booklet 5 is conveyed and moved on the conveying channel 13. The conveying drive mechanism 12 includes a main driving motor (not shown), a conveying active shaft 121, a conveying follower shaft 122 and a conveying belt 123. The conveying active shaft 121 is rotatably arranged at the front end of the conveying frame 11, and the conveying follower shaft 122 is rotatably arranged at the rear end of the conveying frame 11. The conveying belt 123 is sleeved between the conveying active shaft 121 and the conveying follower shaft 122. A plurality of push rods 124 are evenly spaced on the conveying belt 123. A conveying through groove 131 is opened in the middle of the conveying channel 13, and the push rod 124 can pass through the conveying through groove 131. Specifically, in the embodiment of the present invention, the main driving button drives the conveying driving shaft 121 to rotate, thereby driving the conveying belt 123 to move, and the push rod 124 on the conveying belt 123 pushes the booklet 5 to move on the conveying channel 13 .

[0061] In some embodiments, Figure 2 and 14 As shown, the conveying frame 11 also includes two groups of first side frames 111 and two groups of second side frames 112, and the bottom of the first side frames 111 is also provided with supporting feet, and a plurality of stabilizing frames 14 are connected between the two groups of the first side frames 111, and the stabilizing frames 14 are located below the conveying channel 13. The stabilizing frames 14 include a frame body 143, and the top and both sides of the frame body 143 are provided with hinges, and the hinges are used to connect the first side frames 111. The top and bottom of the frame body 143 are respectively provided with a first avoidance groove 141 and a second avoidance groove 142.
