[0003] In a laminated paper production line, two unwinding rollers are usually provided. When the paper on one of the unwinding rollers is about to be unwound, the paper on the unwinding roller is glued together with the paper on the other unwinding roller, so as to achieve continuous unwinding of the paper. In the prior art, the gluing operation is usually performed manually, which affects the production efficiency of the laminated paper. Summary of the invention

[0004] Based on this, it is necessary to provide a continuous production equipment for laminated paper to address the current technical problem of low production efficiency of laminated paper.

[0007] Furthermore, the upper glue squeezing roller has the same structure as the lower glue squeezing roller, and both extend in the left-right direction. A glue coating roller is fixedly provided inside the upper glue squeezing roller, and a storage cavity is provided inside the glue coating roller. The glue is located in the storage cavity. A plurality of glue outlet holes are provided on the glue coating roller, and an avoidance groove is provided on the upper glue squeezing roller. The glue outlet holes are arranged corresponding to the avoidance groove, and the glue flows out through the glue outlet holes. In the initial state, the glue outlet holes of the upper glue squeezing roller correspond to the glue outlet holes of the lower glue squeezing roller in upper and lower directions.

[0008] Furthermore, the gluing mechanism also includes two synchronously retractable telescopic rods, the two telescopic rods correspond to the left and right sides of the paper respectively, and each telescopic rod extends in the front-to-back direction; one end of each telescopic rod is fixed with a limit plate, and the ends of the upper glue squeezing roller and the lower glue squeezing roller are rotatably set on the limit plate, the upper glue squeezing roller is provided with a first gear, and the lower glue squeezing roller is provided with a second gear, and the first gear is meshed with the second gear.

[0009] Furthermore, a swivel is rotatably provided on the upper glue extrusion roller, the inner circumference of the swivel is connected to the storage cavity, a glue storage box is provided on the rotating frame, the outer circumference of the swivel is connected to the glue storage box through a glue pipe, and a water pump is provided in the glue storage box, through which glue is pumped to the glue coating roller of the upper glue extrusion roller and the glue coating roller of the lower glue extrusion roller.

[0010] Furthermore, a driving mechanism is provided at one end of the telescopic rod away from the limiting plate, and the driving mechanism is a hydraulic cylinder. An integrated box is fixedly provided on the rotating frame, and the glue storage box and the hydraulic cylinder are integrated in the integrated box.

[0011] Furthermore, in the left-right direction, the length of the glue coating roller is shorter than the length of the paper.

[0012] Furthermore, viewed from top to bottom, the left and right ends of the glue coating roller are located between the left and right ends of the paper.

[0013] Furthermore, a swing arm bracket is provided on the rear side of the base, and a pressing swing arm and a roller shaft are rotatably provided on the swing arm bracket. A pressure roller is provided on the pressing swing arm, and the pressure roller and the roller shaft both extend in the left and right directions.

[0018] Secondly, since the upper glue squeezing roller and the lower glue squeezing roller rotate synchronously in opposite directions, the paper of the coated paper roll to be unwound moves in a straight line, while the paper of the pre-unwound coated paper roll rotates along the circumference of the rotating shaft. Therefore, after the two are bonded, the coating position of the upper glue squeezing roller on the coated paper roll to be unwound and the coating position of the lower glue squeezing roller on the pre-unwound coated paper roll almost do not overlap, thereby increasing the coating area of ​​the glue and improving the bonding effect.

[0019] Third, in the initial state, the glue outlet hole of the upper glue squeezing roller corresponds to the glue outlet hole of the lower glue squeezing roller in the upper and lower directions, so that glue leakage can be avoided when not in use.

[0020] Fourth, in the left and right directions, the length of the glue coating roller is smaller than the length of the paper. During the bonding process between the paper of the unwound coated paper roll and the paper of the pre-wound coated paper roll, the glue is squeezed and diffused around. This arrangement prevents the glue from leaking from the left and right sides of the paper, thereby affecting the processing quality of the coated paper. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] In one embodiment, a driving mechanism (not shown in the figure) is provided at one end of the telescopic rod 202 away from the limiting plate 203, and the driving mechanism is a hydraulic cylinder. An integrated box 201 is fixed on the rotating frame 107, and the glue storage box and the hydraulic cylinder are integrated in the integrated box 201.

[0042] In one embodiment, in the left-right direction, the length of the glue coating roller 206 is smaller than the length of the paper.

[0043] In one embodiment, from top to bottom, the left and right ends of the glue coating roller 206 are located between the left and right ends of the paper. During the bonding process of the paper of the unrolled coated paper roll and the paper of the pre-rolled coated paper roll, the glue is squeezed and diffused to the surroundings. This arrangement prevents the glue from leaking from the left and right sides of the paper, thereby affecting the processing quality of the coated paper.

[0044] In one embodiment, a swing arm bracket 111 is provided at the rear side of the base, and a pressing swing arm 109 and a roller shaft 112 are rotatably provided on the swing arm bracket 111. A pressing roller 1091 is provided on the pressing swing arm 109, and both the pressing roller 1091 and the roller shaft 112 extend in the left-right direction. The pressing roller 1091 is located in front of the roller shaft 112, and the pressing roller 1091 and the roller shaft 112 press and transport the unrolled paper. A swing arm driving device 110 is provided on the swing arm bracket 111, and the swing arm driving device 110 is used to adjust the angle of the pressing swing arm 109, thereby ensuring the pressing effect of the paper and facilitating subsequent processing.

[0045] In one embodiment, a driving motor 105 and a mounting block 106 are respectively fixed to the left and right ends of the rotating shaft 103 on the rotating frame 107, and the mounting block 106 is used to install the rotating shaft, and the driving motor 105 drives the rotating shaft 103 to rotate relative to the mounting block 106. The driving motor 105 drives the coated paper roll on the rotating shaft 103 to rotate, thereby realizing active unwinding of the paper.

[0046] In one embodiment, two support rollers 1071 are rotatably disposed on the rotating frame 107, and the two support rollers 1071 are alternately distributed with the two rotating shafts 103, and the support rollers 1071 are used to support the unrolled paper, so that the paper can be flattened and the subsequent processing quality can be improved.

[0047] In combination with the above embodiments, the use principle and working process of the embodiments of the present invention are as follows:

[0048] Initially, the first coated paper roll 104 is located on the rotating shaft 103 behind the rotating frame 107, that is, near the swing arm bracket 111, and the corresponding driving motor 105 is controlled to drive the rotating shaft 103 to rotate so that the first coated paper roll 104 is actively unwound, so that the paper moves backward. When the first coated paper roll 104 is about to be unwound, the second coated paper roll 108 is placed on the rotating shaft 103 in front of the rotating frame 107, and the rotating frame 107 is rotated 180 degrees counterclockwise. Figure 1As shown, the first coated paper roll 104 is located in front of the rotating frame 107, and the second coated paper roll 108 is located behind the rotating frame 107. By controlling the corresponding driving motor 105 to drive the rotating shaft 103 to rotate, the second coated paper roll 108 is rotated until the starting end of the paper faces upward and is actively unwound. Then, the upper glue coating mechanism 200 is synchronously controlled to operate, and the telescopic rod 202 is extended by controlling the hydraulic cylinder. The telescopic rod 202 drives the upper glue squeezing roller 205 and the lower glue squeezing roller 209 to move synchronously to the lower side of the first coated paper roll 104 and the upper side of the second coated paper roll respectively, and glue is pumped into the glue coating roller 206 of the upper glue squeezing roller 205 and the glue coating roller 206 of the lower glue squeezing roller 209 by a water pump to extrude the glue. Driven by the paper, the upper glue squeezing roller 205 and the lower glue squeezing roller 209 rotate synchronously in opposite directions. The upper glue squeezing roller 205 can apply glue to the lower side of the paper of the first coated paper roll 104 during the rotation, and the lower glue squeezing roller 209 can apply glue to the upper side of the paper of the second coated paper roll 108 during the rotation, thereby realizing the bonding of the paper of the first coated paper roll 104 and the paper of the second coated paper roll 108, so that there is no need for manual bonding operations, thereby improving the production efficiency of coated paper.

[0049] Before the paper on the second coated paper roll 108 is about to be unwound, the third coated paper roll (not shown in the figure) is replaced on the rotating shaft 103 where the first coated paper roll 104 is located. Therefore, when the paper on the second coated paper roll 108 is about to be unwound, the rotating frame 107 is rotated 180 degrees counterclockwise again, so that the second coated paper roll 108 is rotated to the front and the third coated paper roll is rotated to the back, so that another gluing mechanism 200 can be operated to carry out continuous bonding operations.

[0050] Since the upper glue squeezing roller 205 and the lower glue squeezing roller 209 rotate synchronously in opposite directions, the paper of the coated paper roll to be unwound moves in a straight line, while the paper of the pre-unwound coated paper roll rotates along the circumference of the rotating shaft 103. Therefore, after the two are bonded, the coating position of the upper glue squeezing roller 205 on the coated paper roll to be unwound and the coating position of the lower glue squeezing roller 209 on the pre-unwound coated paper roll almost do not overlap, thereby increasing the coating area of ​​the glue and improving the bonding effect.

[0051] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
