[0022] Embodiments of the present invention will now be described with reference to the accompanying drawings, wherein like reference numerals represent like elements throughout the several views.

[0023] See also Figure 1 and Figure 3The three-mounting and one front gauge alignment mechanism 100 of the present invention comprises a front gauge alignment device 10, a lower mounting conveyor line 20, and a middle mounting conveyor line 30 and an upper mounting conveyor line 40 which are tilted upward relative to the lower mounting conveyor line 20 and rotated and unfolded in sequence, so that the paperboard 200 conveyed by the middle mounting conveyor line 30 and the paperboard 200 conveyed by the upper mounting conveyor line 40 converge at the front gauge alignment device 10. The lower end of the middle mounting conveyor line 30 is located behind the lower end of the upper mounting conveyor line 40 to avoid collision and interference between the paperboards 200 conveyed by the two. The front gauge alignment device 10 includes a plurality of alignment blocks 11, a winding conveying member 12 for performing a rotational motion, a first rotating wheel 13 and a second rotating wheel 14; the first rotating wheel 13 and the second rotating wheel 14 are installed at the front end of the lower mounting conveyor line 20 in a spaced manner one in front of the other, and the winding conveying member 12 is sleeved on the first rotating wheel 13 and the second rotating wheel 14, so that the winding conveying member 12 performs a rotational motion with the cooperation of the first rotating wheel 13 and the second rotating wheel 14; the alignment blocks 11 are fixed to the winding conveying member 12 in a spaced manner along the rotation direction of the winding conveying member 12 and protrude outward from the winding conveying member 12; preferably, the winding conveying member 12 is a chain, and correspondingly, the first rotating wheel 13 and the second rotating wheel 14 are each a sprocket, but this is not limited to it. The lower end of the middle mounting conveyor line 30 is located above between two adjacent alignment blocks 11, so that the cardboard 200 conveyed by the middle mounting conveyor line 30 is blocked by the alignment block 11; the lower end of the upper mounting conveyor line 40 is located above between two adjacent alignment blocks 11, so that the cardboard 200 conveyed by the upper mounting conveyor line 40 is blocked by the alignment block 11. The cardboard 200 conveyed by the lower mounting conveyor line 20, the middle mounting conveyor line 30 and the upper mounting conveyor line 40 at the same time are aligned with each other under the blocking of the block 11. For example, Figure 3 As shown, the cardboard 200 conveyed by the lower mounting conveyor line 20 is Figure 3 The leftmost alignment block 11 in the middle mounting conveyor line 30 is blocked by the alignment block 11 next to the leftmost alignment block 11, and the upper mounting conveyor line 40 is blocked by the alignment block 11 next next to the leftmost alignment block 11, so as to realize the alignment of the paperboards 200 conveyed by the lower mounting conveyor line 20, the middle mounting conveyor line 30 and the upper mounting conveyor line 40, but not limited to this. More specifically, as follows:

[0024] like Figure 2 and Figure 3As shown, the lower mounting conveyor line 20 comprises a lower mounting left frame 21, a lower mounting right frame 22, a first lower mounting shaft 23, a second lower mounting shaft 24, a first transmission wheel 25, a second transmission wheel 26, a first rotary conveying member 27 and a second rotary conveying member 28. The first lower mounting shaft 23 is inserted into the front end of both the lower mounting left frame 21 and the lower mounting right frame 22, and the second lower mounting shaft 24 is inserted into the rear end of both the lower mounting left frame 21 and the lower mounting right frame 22. The first transmission wheel 25 and the first rotating wheel 13 are respectively mounted on the left end and the right end of the first lower mounting shaft 23, and the second transmission wheel 26 and the second rotating wheel 14 are respectively mounted on the lower mounting left frame 21 and the lower mounting right frame 22, and the second rotating wheel 14 is located in front of the second transmission wheel 26. The first rotary conveying member 27 is sleeved on the first transmission wheel 25 and the second transmission wheel 26 on the lower mounting left side frame 21, and the second rotary conveying member 28 is sleeved on the first transmission wheel 25 and the second transmission wheel 26 on the lower mounting right side frame 22, so as to convey the cardboard 200 on both sides, improve the conveying reliability of the cardboard 200, and reduce the weight of the lower mounting conveyor line 20. The first rotating wheel 13 and the second rotating wheel 14 on the lower mounting left side frame 21 are sleeved with the winding conveying member 12, and the first rotating wheel 13 and the second rotating wheel 14 on the lower mounting right side frame 22 are sleeved with the winding conveying member 12, and each winding conveying member 12 is fixed with a positioning block 11 to block and align the cardboard 200 from both sides of the cardboard 200, so the reliability is better. Specifically, the lower mounting conveyor line 20 further includes a lower mounting lateral correcting mechanism 29, which is respectively installed at the top of the lower mounting left frame 21 and the lower mounting right frame 22, and the conveying member 12, the first rotary conveying member 27 and the second rotary conveying member 28 are respectively located between the lower mounting lateral correcting mechanism 29 to provide conveying guidance for the cardboard 200 from both sides of the cardboard 200, thereby improving the smoothness of conveying the cardboard 200. For example, the lower mounting lateral correcting mechanism 29 includes a first side guide pulley 291, a second side guide pulley 292 and a side guide belt 293 sleeved on the first side guide pulley 291 and the second side guide pulley 292 to simplify the structure of the lower mounting lateral correcting mechanism 29, but the invention is not limited thereto. In addition, the first rotary conveying member 27 and the second rotary conveying member 28 are each a belt to improve the reliability of the lower mounting conveyor line 20 in conveying the cardboard 200, but the invention is not limited thereto. It is understandable that when the external power mechanism drives the first lower mounting shaft 23 to rotate, the rotating first lower mounting shaft 23 can make the first rotary conveying member 27 and the second rotary conveying member 28 perform synchronous and coordinated return motion, and at the same time, drive the winding conveying member 12 to perform synchronous rotation, but not limited to this. A differential conveying line 50 is provided between the lower mounting left frame 21 and the lower mounting right frame 22, which is used to speed up the conveying of the cardboard 200 conveyed by the lower mounting conveying line 20, so that the conveying of the cardboard 200 is temporarily stopped when it is blocked by the alignment block 11, but not limited to this.

[0025] like Figure 5 As shown, the mounting conveyor line 40 includes a mounting left frame 41, a mounting right frame 42, a first mounting shaft 43, a second mounting shaft 44, a first mounting wheel 45, a second mounting wheel 46, a first mounting winding member 47 and a second mounting winding member 48. The first mounting shaft 43 is inserted at the front end of the mounting left frame 41 and the mounting right frame 42, and the second mounting shaft 44 is inserted at the rear end of the mounting left frame 41 and the mounting right frame 42. The first mounting wheel 45 is respectively installed at the left end and the right end of the first mounting shaft 43, and the second mounting wheel 46 is respectively installed at the rear end of the mounting left frame 41 and the mounting right frame 42. The first mounting winding member 47 is sleeved on the first mounting wheel 45 and the second mounting wheel 46 on the mounting left side frame 41, and the second mounting winding member 48 is sleeved on the first mounting wheel 45 and the second mounting wheel 46 on the mounting right side frame 42. The purpose of such arrangement is to convey the cardboard 200 from both sides of the cardboard 200, improve the reliability of conveying the cardboard 200, and reduce the weight of the mounting conveyor line 40. Specifically, the mounting left side frame 41 and the mounting right side frame 42 are each equipped with a row of paper suction fans 49a and a mounting lateral straightening mechanism 49b. The paper suction fan 49a on the mounting left side frame 41 is located in the inner ring of the first mounting winding member 47, and the paper suction fan 49a on the mounting right side frame 42 is located in the inner ring of the second mounting winding member 48. The first mounting winding member 47 and the second mounting winding member 48 are each located between the mounting lateral straightening mechanism 49b, which can further increase the reliability of conveying the cardboard 200. For example, the first mounting winding member 47 and the second mounting winding member 48 are belts, and correspondingly, the first mounting wheel 45 and the second mounting wheel 46 are pulleys, but the present invention is not limited thereto. It is understandable that when the external power mechanism drives the first mounting shaft 43 to rotate, the rotating first mounting shaft 43 can make the first mounting winding member 47 and the second mounting winding member 48 perform synchronous and coordinated return motion, but the present invention is not limited thereto. In addition, since the upper mounting lateral straightening mechanism 49b and the lower mounting lateral straightening mechanism 29 have exactly the same structure, the upper mounting lateral straightening mechanism 49b can refer to the structure of the lower mounting lateral straightening mechanism 29, so it will not be described here.

[0026] like Figure 4As shown, the mounting conveyor line 30 includes a mounting left frame 31, a mounting right frame 32, a first mounting shaft 33, a second mounting shaft 34, a first mounting wheel 35, a second mounting wheel 36, a first mounting winding member 37, and a second mounting winding member 38. The first mounting shaft 33 is inserted at the front end of the mounting left frame 31 and the mounting right frame 32, and the second mounting shaft 34 is inserted at the rear end of the mounting left frame 31 and the mounting right frame 32. The first middle mounting wheel 35 is respectively installed at the left end and the right end of the first middle mounting shaft 33, and the second middle mounting wheel 36 is respectively installed at the rear ends of the middle mounting left frame 31 and the middle mounting right frame 32; the first middle mounting winding piece 37 is sleeved on the first middle mounting wheel 35 and the second middle mounting wheel 36 on the middle mounting left frame 31, and the second middle mounting winding piece 38 is sleeved on the first middle mounting wheel 35 and the second middle mounting wheel 36 on the middle mounting right frame 32; so that the cardboard 200 is conveyed from both sides of the cardboard 200, the conveying reliability of the cardboard 200 is improved, and at the same time, the weight of the middle mounting conveying line 30 can be simplified. Specifically, the left frame 31 and the right frame 32 of the middle mounting are each equipped with a row of paper suction fans 39a and a middle mounting lateral straightening mechanism 39b, the paper suction fan 39a of the left frame 31 of the middle mounting is located in the inner ring of the first middle mounting winding member 37, the paper suction fan 39a of the right frame 32 of the middle mounting is located in the inner ring of the second middle mounting winding member 38, and the first middle mounting winding member 37 and the second middle mounting winding member 38 are each located between the middle mounting lateral straightening mechanism 39b; this can further increase the reliability of the paperboard 200 conveying. For example, the first middle mounting winding member 37 and the second middle mounting winding member 38 are each belts, and correspondingly, the first middle mounting wheel 35 and the second middle mounting wheel 36 are each pulleys, but not limited to this. It can be understood that when the external power mechanism drives the first middle mounting shaft 33 to rotate, the rotating first middle mounting shaft 33 can make the first middle mounting winding member 37 and the second middle mounting winding member 38 perform synchronous and coordinated return motion, but not limited to this. In addition, since the structures of the middle mounting lateral correcting mechanism 39b and the lower mounting lateral correcting mechanism 29 are completely the same, the structure of the middle mounting lateral correcting mechanism 39b can refer to the structure of the lower mounting lateral correcting mechanism 29, so it will not be repeated here.

[0027] Compared with the prior art, since the middle mounting conveyor line 30 and the upper mounting conveyor line 40 are inclined upward relative to the lower mounting conveyor line 20 and rotate and unfold in sequence, the cardboard 200 conveyed by the upper mounting conveyor line 40 and the cardboard 200 conveyed by the middle mounting conveyor line 30 intersect at the lower mounting conveyor line 20; and the lower end of the middle mounting conveyor line 30 is located behind the lower end of the upper mounting conveyor line 40, so as to avoid the cardboard 200 conveyed by the upper mounting conveyor line 40 from impacting and colliding with the cardboard 200 conveyed by the middle mounting conveyor line 30; at the same time, since the front gauge alignment device 10 includes a plurality of alignment blocks 11, a winding conveying member 12 for rotating motion, a first rotating wheel 13 and a second rotating wheel 14, the first rotating wheel 13 and the second rotating wheel 14 are installed one in front and one behind with a spacing. At the front end of the lower mounting conveyor line 20, the winding conveyor member 12 is sleeved on the first rotating wheel 13 and the second rotating wheel 14, and the alignment block 11 is fixed to the winding conveyor member 12 at intervals along the rotation direction of the winding conveyor member 12 and protrudes outward from the winding conveyor member 12. The lower end of the middle mounting conveyor line 30 is located above between two adjacent alignment blocks 11, and the lower end of the upper mounting conveyor line 40 is located above between another two adjacent alignment blocks 11. Therefore, under the action of the corresponding alignment block 11, the cardboard 200 conveyed simultaneously by the lower mounting conveyor line 20, the middle mounting conveyor line 30 and the upper mounting conveyor line 40 are aligned with each other due to the blocking of the alignment block 11, thereby improving the laminating accuracy and production efficiency of the upper cardboard, the middle cardboard and the lower cardboard.

[0028] It should be noted that the direction indicated by arrow A in the drawings is from front to back, and the direction indicated by arrow B is from left to right; wherein, the direction in which the lower mounting conveyor line 20 conveys the cardboard 200 is shown in FIG. Figure 1 The arrow next to the lower mounting conveyor line 20 in FIG. 1 indicates the direction in which the middle mounting conveyor line 30 conveys the cardboard 200. Figure 1 The direction of the cardboard 200 conveyed by the upper mounting conveyor line 40 is shown in FIG. Figure 1 The arrow next to the mounting conveyor line 40 in FIG.

[0029] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
