Referring to fig. 1-2, the present utility model provides a paper winding structure, which includes: a first side plate 1 and a second side plate 17 disposed opposite to each other; a winding mechanism 2 located between the first side plate 1 and the second side plate 17, where the winding mechanism 2 is used for winding paper 21; a lifting platform 3 located between the first side plate 1 and the second side plate 17; the adjusting mechanism 5 is located between the first side plate 1 and the second side plate 17, a cutting assembly 4 and a gluing assembly are installed on the adjusting mechanism 5, the cutting assembly 4 is used for cutting off the paper 21 on the lifting platform 3, and the gluing assembly is used for gluing at the cutting position of the paper 21.

In this embodiment, the first side plate 1 and the second side plate 17 are parallel to each other and are located in the vertical direction, the first side plate 1 and the second side plate 17 are used as a supporting structure of the whole winding structure, the adjusting mechanism 5 can drive the cutting assembly 4 and the gluing assembly to move in the horizontal direction and the vertical direction, the cutting assembly 4 and the gluing assembly are located above the lifting platform 3, the paper 21 passes through the top surface of the lifting platform 3 first, and then reaches the winding mechanism 2.

When the paper 21 is rolled to a proper thickness by the rolling mechanism 2, the cutting assembly 4 and the gluing assembly are driven to move by the adjusting mechanism 5, and the cutting assembly 4 cuts off the paper 21 conveyed to the lifting platform 3. The cut portion of the sheet 21 is glued by the gluing assembly while the sheet 21 is cut, and then the sheet 21 of the remaining cut portion is wound up by the winding mechanism 2. Since glue is applied to the cut portions of the paper 21, the cut portions of the paper 21 are directly adhered to the winding. Thus, when the paper 21 is rolled to a proper thickness, the paper 21 is not required to be cut off by special manpower, and the cutting part of the paper 21 is not required to be glued by special manpower, so that the rolling efficiency of the paper 21 is improved.

In one possible implementation, please refer to fig. 2 again, the winding mechanism 2 includes: a first wind-up roller 201 and a second wind-up roller 202 which are arranged between the first side plate 1 and the second side plate 17 and are parallel to each other; a winding drum 11 located between the first winding roller 201 and the second winding roller 202 and disposed along an axial direction of the first winding roller 201, where the winding drum 11 is used for winding paper 21; and a winding press roller 20 positioned between the first side plate 1 and the second side plate 17, wherein the winding press roller 20 is used for pressing the winding drum 11.

In this embodiment, the first winding roller 201, the second winding roller 202 and the winding press roller 20 may be connected to the first side plate 1 and the second side plate 17 through bearings, and the end of the first winding roller 201 is connected to the power mechanism. The upper sides of the first wind-up roller 201 and the second wind-up roller 202 are located on the same horizontal plane, and as a preferred mode, the axes of the first wind-up roller 201 and the second wind-up roller 202 are located on the same horizontal plane, and the outer diameters of the first wind-up roller 201 and the second wind-up roller 202 are equal.

The winding drum 11 is pressed on the first winding roller 201 and the second winding roller 202 through the winding press roller 20, when the power mechanism drives the first winding roller 201 to rotate (such as anticlockwise rotation) in the direction of conveying the paper 21, the first winding roller 201 can give a certain friction force to the winding drum 11, under the action of the friction force, the winding drum 11 can rotate along the opposite direction of rotating the first winding roller 201, the winding drum 11 rotates to give a certain friction force to the second winding roller 202 and the winding press roller 20, and accordingly the second winding roller 202 and the winding press roller 20 are driven to rotate along the opposite direction of rotating the winding drum 11. After the winding drum 11 rotates, the paper 21 is driven to continue winding on the winding drum 11. In this way, with the cooperation of the first winding roller 201, the second winding roller 202, the winding drum 11, and the winding press roller 20, automatic winding of the paper 21 can be achieved.

In a possible implementation, referring again to fig. 2, a rotating motor 18 is mounted on the second side plate 17, a first pulley is mounted on a motor shaft of the rotating motor 18, a second pulley is mounted on an end portion of the first wind-up roller 201, and a belt 19 is mounted between the first pulley and the second pulley.

In this embodiment, the rotating motor 18 is a conventional motor, when the first wind-up roller 201 is required to rotate, the rotating motor 18 is controlled to rotate in a conventional manner, the rotating motor 18 rotates and then drives the first belt wheel to rotate, the first belt wheel rotates and drives the second belt wheel to rotate through the belt 19, and the second belt wheel drives the first wind-up roller 201 to rotate. Thus, by rotating the motor 18, it is possible to more easily rotate the first winding roller 201, thereby more easily winding the paper 21 around the winding drum 11.

In a possible implementation manner, please refer to fig. 2 again, a first cylinder 16 is installed on a side surface of the first side plate 1, a first sliding unit is installed on a piston rod of the first cylinder 16, a second cylinder is installed on a side surface of the second side plate 17, a second sliding unit is installed on a piston rod of the second cylinder, and the winding press roller 20 is installed between the first sliding unit and the second sliding unit.

In this embodiment, the first air cylinder 16 and the second air cylinder are conventional air cylinders, when the winding roller 20 is required to compress the winding drum 11, the pistons of the first air cylinder 16 and the second air cylinder are controlled to synchronously extend in a conventional manner, and the first air cylinder 16 and the second air cylinder respectively apply forces to the first sliding component and the second sliding component in the direction of the winding drum 11, and after the first sliding component and the second sliding component receive forces in the direction of the winding drum 11, the first sliding component and the second sliding component drive the winding roller 20 to slide in the direction of the winding drum 11 until the winding roller 20 compresses the winding drum 11.

Since the amount of the paper 21 wound around the winding drum 11 is small after the paper 21 is cut, the cut paper 21 is wound around the winding drum 11 without changing the thickness of the paper 21 wound around the winding drum 11 too much, and therefore, the winding roller 20 is not required to automatically move in a direction away from the winding drum 11. In this way, the first cylinder 16 and the second cylinder can more conveniently compress the winding roller 11 by the winding roller 20, so that the winding roller 11 can better wind the paper 21.

In a possible implementation manner, referring to fig. 3, the first sliding unit includes a first sliding block 15 and a first sliding rail 14 located in a vertical direction, the first sliding rail 14 is mounted on the first side plate 1, the first sliding block 15 is slidably connected with the first sliding rail 14, and a piston rod of the first cylinder 16 is connected with the first sliding block 15; the second sliding unit comprises a second sliding block and a second sliding rail positioned in the vertical direction, the second sliding rail is arranged on the second side plate 17, the second sliding block is in sliding connection with the second sliding rail, and a piston rod of the second air cylinder is connected with the second sliding block; the winding press roller 20 is installed between the first slide block 15 and the second slide block.

In this embodiment, when the winding roller 20 moves in the direction of the winding drum 11, the first slider 15 slides along the length direction of the first slide rail 14, and the second slider slides along the length direction of the second slide rail. Because the first slide rail 14 is arranged on the first side plate 1, the second slide rail is arranged on the second side plate 17, and the rolling press roller 20 is arranged between the first slide block 15 and the second slide block. Therefore, the winding roller 20 can be moved more stably in the direction of the winding drum 11.

In a possible implementation manner, referring to fig. 1 again, a separating mechanism is further disposed between the first side plate 1 and the second side plate 17, and the separating mechanism is used for separating the paper 21. The roll separating mechanism comprises: a first roller 12 and a second roller 10 which are positioned between the first side plate 1 and the second side plate 17 and are parallel to each other; the winding drum 11 may be located between the first roller 12 and the second roller 10 and disposed along the length direction of the first roller 12, and the winding drum 11 is used for separating the paper sheets 21; a flexible lifting mechanism located between the first side plate 1 and the second side plate 17; the separating and rolling press roller 6 and the oblique slotting cutter 7 are positioned on the flexible lifting mechanism, the separating and rolling press roller 6 is used for pressing the rolling cylinder 11, and the oblique slotting cutter 7 is used for attaching the paper 21 on the winding cylinder; and a horizontal cutter 13 disposed between the first side plate 1 and the second side plate 17, wherein the horizontal cutter 13 is used for moving the paper 21 in the direction of the oblique cutter 7.

The first roller 12, the second roller 10 and the separating roller 6 can be connected with the first side plate 1 and the second side plate 17 through bearings, and the ends of the first roller 12 and the second roller 10 are connected with a power mechanism. The upper sides of the first roller 12, the second roller 10, the first winding roller 201 and the second winding roller 202 are positioned on the same horizontal plane. When the first roller 12 and the second roller 10 are rotated, the first roller 12 and the second roller 10 give a certain friction force to the take-up drum 11, and the take-up drum 11 is rotated in the opposite direction to the rotation of the first roller 12 and the second roller 10 by the friction force.

The flexible lifting mechanism can drive the separating compression roller 6 and the oblique slotting cutter 7 to move towards the winding drum 11 and move away from the winding drum 11. As the thickness of the paper 21 on the winding drum 11 increases, the paper 21 wound around the winding drum 11 gives a reverse force to the separation roller 6, and under the reverse force, the flexible lifting mechanism can automatically move in a direction away from the winding drum 11. However, in this process, the separation roller 6 is always in contact with the paper 21 wound around the winding drum 11 so as to press the winding drum 11 against the first roller 12 and the second roller 10, preventing the winding drum 11 from being separated from the first roller 12 and the second roller 10.

When the separating roller 6 presses on the winding drum 11, the winding drum 11 can give the separating roller 6 a corresponding friction force, under the action of the friction force, the separating roller 6 can rotate towards the opposite direction of the winding drum 11, and under the rotation of the separating roller 6, the paper 21 can be more favorably wound on the winding drum 11 continuously, and finally, a finished product wound on the winding drum 11 can be silver-collecting paper and the like. The inclination angle of the oblique slotting tool 7 can be set according to practical requirements, and the oblique slotting tool 7 has the function of obliquely inserting the end part of the paper 21 on the lower side surface of the winding drum 11, so that the paper 21 completes the first winding on the winding drum 11.

Based on the above design, when the paper 21 is wound on the winding drum to a certain thickness, the winding drums on the first roller 12 and the second roller 10 are pushed onto the winding mechanism 2, and the paper 21 is cut off. Referring to fig. 4, the winding drum of the unreeled paper 21 is placed on the first roller 12 and the second roller 10 while the winding drum of the wound paper 21 is pushed, and at this time, the paper 21 passes through the lower side of the winding drum. Referring to fig. 5, the horizontal slotting tool 13 is then controlled to move in the direction of the take-up reel and the paper 21 is wound around the upper side of the take-up reel in the opposite direction.

Simultaneously, the flexible lifting mechanism moves downwards to drive the winding roller 6 and the oblique slotting cutter 7 to move towards the winding drum together until the winding drum is tightly pressed by the winding roller 6. Referring to fig. 6, the oblique cutting tool 7 is then moved obliquely in the direction of the take-up drum until the oblique cutting tool 7 inserts the end of the paper 21 obliquely to the lower side of the take-up drum. So, under the cooperation of horizontal slotting tool 13 and oblique slotting tool 7, the first round of paper 21 twines on the receipts reel, then control first roller 12 and second roller 10 rotation, and first roller 12 and second roller 10 rotate and drive the receipts reel rotation again, under the rotatory drive of receipts reel, can continue winding paper 21 on the receipts reel. Thus, the sheet 21 can be wound around the winding drum without requiring a manual work, and the efficiency of separating the sheet 21 can be improved.

In a possible implementation, referring again to fig. 1, the cross beam 25 is provided with a bevel cylinder 8, and the bevel blade 7 is mounted on a piston rod of the bevel cylinder 8.

In this embodiment, the power mechanism driving the bevel blade 7 to bevel is preferably a bevel cylinder 8, and the bevel cylinder 8 is a conventional cylinder. When the oblique slotting tool 7 is required to move obliquely, the piston rod of the oblique cutting cylinder 8 is controlled to extend through a conventional controller, and the oblique slotting tool 7 is driven to move towards the winding drum 11. Through setting up chamfer cylinder 8, can be more convenient for the removal of oblique slotting tool 7 to and compare the manpower and drive oblique slotting tool 7 and remove, can reduce corresponding intensity of labour.

In one possible implementation, the horizontal slotting tool 13 is provided with a leveling component for leveling the paper 21.

In the present embodiment, when the horizontal slotting tool 13 inserts the paper 21 reversely to the upper portion of the take-up reel 11, there is a possibility that the paper 21 is uneven, such as having wrinkles or the like in some portions of the paper 21. If the paper 21 is uneven, the paper 21 is wound around the winding drum 11, which affects the quality of the final paper product. Thus, by providing the leveling assembly on the horizontal slotting tool 13, the paper 21 can be leveled more, and the quality of the final paper product can be improved.

In a possible implementation manner, referring to fig. 7, the leveling assembly includes an air pipe 22 installed on the top surface of the horizontal slotting tool 13 and disposed along the width direction thereof, the air pipe 22 is in communication with an air source, and a plurality of air nozzles 23 facing the winding drum are opened on the air pipe 22 along the width direction of the horizontal slotting tool 13.

In this embodiment, in order to mount the air pipe 22 on the horizontal slotting tool 13 more stably, a groove may be formed in the horizontal slotting tool 13 along the width direction thereof, so that the air pipe 22 is mounted in the groove. When the horizontal slotting tool 13 moves towards the winding drum, the air pipe 22 is controlled to be connected with an air source in a conventional mode, air of the air source enters the air pipe 22 and is blown to the paper 21 at the winding drum from the air nozzles 23 on the air pipe 22, and the air blown from the air nozzles 23 can blow the paper 21 to be flat, so that the paper 21 can be wound on the winding drum more flatly.

In one possible implementation, referring to fig. 8, the flexible lifting mechanism includes: a power cylinder 29; a first slide assembly located on the first side plate 1; a second sliding component located on the second side plate 17, the first sliding component being disposed opposite to the second sliding component; the cross beam 25 is connected with the first sliding component and the second sliding component, and the rolling press roller 6 and the oblique slotting cutter 7 are both arranged on the cross beam 25; a chain 27 connected to the power cylinder 29 and the cross beam 25.

In this embodiment, a transverse frame 30 is installed between the upper portion of the first side plate 1 and the upper portion of the second side plate 17, a power cylinder 29 may be installed in the transverse frame 30, a sprocket 28 may be installed in the transverse frame 30, and a chain 27 is wound on the sprocket 28 and then connected to the cross beam 25, so that the chain 27 is driven to move up and down by the power cylinder 29.

When the separating roller 6 and the oblique slotting tool 7 need to move towards the winding drum, the piston rod of the power cylinder 29 is controlled to stretch out in a conventional mode, and under the action of the gravity of the cross beam 25, the separating roller 6, the oblique slotting tool 7 and the like, the cross beam 25, the separating roller 6, the oblique slotting tool 7 and the like move towards the winding drum 11 along with the stretching of the chain 27 until the separating roller 6 presses the winding drum 11, and then the piston rod of the power cylinder 29 is stopped from stretching out. When the thickness of the sheet 21 wound around the winding drum 11 increases, the cross member 25, the separation roller 6, and the bevel blade 7 move upward as a whole with the thickness of the sheet 21 under the action of the sheet 21. In this way, by connecting the cross beam 25 with the piston rod of the power cylinder 29 by means of the chain 27, flexible adjustment of the cross beam 25 can be achieved, so that the cross beam 25 can automatically move upwards as the thickness of the sheet 21 on the take-up reel 11 increases.

In a possible implementation manner, referring again to fig. 8, a first supporting block and a second supporting block are mounted on each of the first side plate 1 and the second side plate 17, the first sliding component and the second sliding component each include a sliding rod 24 located between the first supporting block and the second supporting block, the sliding rod 24 is slidably connected with the cross beam 25 through a sliding block 26, and the sliding rod 24 is located in a vertical direction. When the cross beam 25 moves in the vertical direction, the sliding block 26 slides along the sliding rod 24, so that the cross beam 25 can move in the vertical direction more stably.

In one possible implementation, a dust cover may be further provided between the cross frame 30 and the cross beam 25, through which the chain 27 passes, the dust cover having flexibility that expands and contracts as the cross beam 25 moves up and down.
