TECHNICAL FIELD
[0001] The present application belongs to the technical field of papermaking, and relates to a broken-proof paper rewinding system. BACKGROUND
[0002] Papermaking technology is divided into two forms of organic mechanism and manual work. The mechanism is continuously carried out on a papermaking machine, paper pulp suitable for paper quality is diluted to a certain concentration with water, wet paper is formed in the net part of the papermaking machine, and then dehydrated by pressing, and then dried into paper. The manual work is to use a frame with a bamboo screen, a polyester net or a copper net to make wet paper by copying the fibers dispersed and suspended in water, and then dehydrated by pressing, and then dried into paper by sunning or drying.
[0003] At present, in the machine-made paper, the paper needs to be rewound at the end of production or in production, so as to be transferred to other places for subsequent processing or to become finished products; during rewinding, there are usually a horizontal winding roller, a machine frame for supporting and driving the winding roller and a motor; during winding, a paper tube is first sleeved on the winding roller, and then the end of the paper to be wound is adhered to the paper tube by adhesive tape; then the motor drives the winding roller and the paper tube to rotate, and the paper is wound on the paper tube. It is found in practice that many papers have a large width (width), and the adhesive tape usually only adheres to the middle part of the paper and the paper tube, which will cause part of the paper not to be adhered to the paper tube by the adhesive tape, which will easily cause the paper at the edge of the adhesive tape to be broken; secondly, even if the worker adopts the full coverage method to paste the edge of the paper to the paper tube, although the end of the paper can be prevented from being broken to a certain extent, this method is not only inconvenient to operate (the paper tube is long and the paper is flexible), but also prone to paste deviation, resulting in winding inclination or paper folding, and thus the operation is less convenient in practice.

[0077] The outer wall of the rubber brush wheel 12 can only act on the rewinding paper tube 5. When the rubber brush wheel 12 is separated from the rewinding paper tube 5, there is still a certain gap between the rubber brush wheel 12 and the rewinding roller 1, that is, the two are not actually in contact. The specific size can be selected according to actual conditions; this can prevent glue from adhering to the rewinding roller 1, so that subsequent use can proceed normally.
[0078] After the glue is applied to the entire length of the rewinding paper drum 5 by the glue brushing wheel 12, the paper can be fully adhered to the outer wall of the rewinding paper drum 5, so that the force applied to the paper when being pulled can be wider, preventing the end of the paper from being damaged; secondly, when applying glue, it is only necessary to move the glue coating rack 8 along the length direction of the guide frame. Compared with the all-round use of tape, the glue application speed of this application is faster. Secondly, the first sliding part 9 and the second sliding part 10 are both arc-shaped, so that they can be better buckled on the guide frame, ensuring the stability of the movement of the guide frame and the glue coating rack 8; according to actual conditions, ball bearings can also be set on the inner walls of the first sliding part 9 and the second sliding part 10 to reduce sliding resistance and wear. At the same time, the first sliding part 9 and the second sliding part 10 also have a certain width, preferably greater than or equal to 5 cm, so that the angular stability of the glue coating rack 8 can be improved and tilting will not occur.
[0079] During the movement of the glue coating rack 8, the static friction between the rewinding paper drum 5 and the glue-brushing wheel 12 causes the glue-brushing wheel 12 to rotate, which in turn drives the glue-transferring wheel 15 to rotate. The glue-transferring wheel 15 rotates, which in turn drives the glue in the glue-receiving dish 16 onto the glue-receiving dish 16, thereby ensuring that the glue-brushing wheel 12 is continuously covered with glue, thereby ensuring a good glue-brushing effect. In actual use, the glue-receiving dish 16 may be provided with a lid to prevent glue from spilling, and the lid may have an opening for the glue-transferring wheel 15 to move.
[0080] Moreover, since the outer wall of the rewinding paper cylinder 5 is an outwardly convex arc shape, and the outer wall of the rubber brush wheel 12 is an inwardly concave shape, the rubber brush wheel 12 can better apply glue to the rewinding paper cylinder 5; and the side of the glue transfer wheel 15 is also outwardly protruding, which can better transfer the glue to the rubber brush wheel 12, thereby ensuring the glue brushing effect and the adhesion effect to the paper.
[0081] After the glue is applied, the glue coating rack 8 is removed; then the end of the paper is adhered to the rewinding paper drum 5, and the rewinding motor 4 drives the rewinding roller 1 to rotate, and the rewinding roller 1 drives the rewinding paper drum 5 to rotate, thereby winding the paper onto the rewinding paper drum 5. In this process, the inner wall of the rewinding paper drum 5 is stretched by the outer side of the first positioning portion 32a, so that the rewinding paper drum 5 can rotate with the rewinding roller 1; according to actual conditions, a protrusion or groove is provided on the outer side of the first positioning portion 32a to increase resistance; secondly, the outer wall of the first positioning portion 32a is in an outward arc shape, which increases the area of interaction with the rewinding paper drum 5; the rewinding paper drum 5 can undergo a certain degree of deformation, thereby locking on the first positioning portion 32a and preventing the rewinding paper drum 5 and the rewinding roller 1 from rotating relative to each other;
[0082] Secondly, the connection length between one end of the rewinding roller 1 and the first support frame 2 is certain, so as to ensure the connection stability between the rewinding roller 1 and the first support frame 2 and the structural stability; secondly, the two ends of the rewinding roller 1 are supported by the first support frame 2 and the second support frame 3 (supported by the support cover 46) respectively during the winding process, so that the winding can be stably carried out, and the gravity of the paper roll can also be well borne.
[0083] During the winding process, the subsequent paper is pressed on the paper roll by the pressing part 17b under the action of the first elastic member 22 and the force applying rod 20, and as the winding work is carried out, the paper roll diameter becomes larger, and the pressing part 17b can also be driven to tilt upward and move, so that the paper roll can be continuously pressed, so as to ensure the tightness of the paper roll winding and the quality of the winding;
[0084] Moreover, as the diameter of the paper roll becomes larger, the required pressure becomes larger; because the paper roll is relatively soft inside when it is large, if the pressure is not enough, the paper roll will become more and more fluffy and the diameter will expand, which is not conducive to subsequent packaging and the stability of the paper roll; therefore, when the pressing part 17b gradually rotates upward, the compression degree of the first elastic member 22 is larger, so that the paper can be better pressed on the paper roll, and the winding effect of the paper roll is ensured or provided.
[0085] When the winding is completed, the paper is first disconnected, and the end of the paper is attached to the paper roll by using adhesive tape; or the end of the paper is attached and fixed to the paper roll after the brush glue wheel 12 brushes glue on the end of the paper roll (the brush glue wheel 12 can be operated in suspension or through a guide frame, and the glue can also be brushed on the entire length of the paper roll at this time); then the forklift or other structures (such as a crane, etc.) bear the gravity of the paper roll;
[0086] Then the second adjusting motor 45 drives the second lead screw 44 to rotate, drives the support cover 46 backward, so that the support cover 46 is separated from the rewinding roller 1; until the support cover 46 is separated from the rewinding roller 1 and the popped-out positioning column 34, the first adjusting motor 42 drives the first lead screw 41 to rotate, moves the second support frame 3 backward, so that the second support frame 3 can not affect the paper roll to be taken out.
[0087] When the support cover 46 is separated from the rewinding roller 1, the positioning post 34 moves outward from the positioning hole 30 under the elastic force of the second elastic member 37 (if the positioning post 34 cannot move outward naturally at this time, the worker can also pull the positioning post 34 outward after the middle threaded connection bolt at the end of the positioning post 34 away from the first support frame 2 to assist the positioning post 34 to move outward); until the inclined inner wall of the drive groove 35 acts on the drag reduction ball 33, at this time, under the pressure of the rewinding paper drum 5, the positioning member 32 moves toward the axial direction of the rewinding roller 1, and the rewinding paper drum 5 can be more easily removed from the rewinding roller 1. In the present application, it is preferred that there is a magnetic attraction between the positioning post 34 and the positioning member 32 (that is, at least one of the two is made of magnetic material), so that when the positioning post 34 moves outward from the positioning hole 30, it can naturally attract the positioning member 32 to move and assist the positioning member 32 to separate from the rewinding paper drum 5.
[0088] When the support cover 46 moves in translation, it can avoid interacting with the positioning column 34. At the same time, when the support cover 46 is in a separated state from the rewinding roller 1, it continues to drive the second support frame 3 to move backward, and can abut against the lower side of the passive wheel 50 through the separation portion 48, so that the articulated frame 6 can be further rotated upward, so that the pressing portion 17b is separated from the paper roll to a certain extent, which facilitates the separation of the paper roll.
[0089] After that, a forklift or the like slightly lifts the paper roll and moves the paper roll away from the first support frame 2 , and the rewinding paper drum 5 with the rewound paper roll is removed from the rewinding roller 1 , and then a new rewinding paper drum 5 is sleeved on the rewinding roller 1 .
[0090] After the new rewinding paper drum 5 is sleeved, the first adjusting motor 42 drives the second adjusting frame 39 to move toward the direction close to the rewinding roller 1, and at this time the separating portion 48 is separated from the passive wheel 50; at this time, under the elastic force of the first elastic member 22, the force rod 20 is rotated upward, and the guide frame is rotated downward, and gradually approaches the rewinding paper drum 5; in this process, since the release rod 24 and the piston disc 25 both move upward, the external air needs to enter the release cylinder 27 through the release hole 28 before the pressing portion 17b can move downward; since the diameter of the release holes 28 in the present application is very small (preferably millimeter level, and the number is small), the speed at which the air enters the release cylinder 27 is slow, which naturally slows down the pressing portion 17b. The speed of downward movement prevents excessive impact between the pressing part 17b and the rewinding paper drum 5, and protects the pressing part 17b and the rewinding paper drum 5; but it should also be understood that when rewinding, the diameter of the paper roll increases slowly, so that the air in the slow-release cylinder 27 can be discharged normally; secondly, when rewinding, the equipment is prone to shaking, etc. If the pressing part 17b is subjected to a sudden large force during shaking, the diameter of the slow-release hole 28 is small at this time, so the pressing part 17b can be better prevented from excessive upward movement, that is, even if the rewinding roller 1 shakes, etc., the pressing part 17b can still stably press the paper roll, thereby ensuring the pressing effect of the paper roll.
[0091] When the pressing portion 17b is pressed against the rewinding paper drum 5, the support cover 46 also moves to a position facing the rewinding roller 1; then the second motor starts and drives the second support frame 3 and the support cover 46 to move toward the rewinding roller 1, and finally the support cover 46 is movably sleeved on the matching groove 47 at the end of the rewinding roller 1;
[0092] During the movement, the support cover 46 also abuts against the outer end of the positioning column 34 (if a bolt was previously connected to the end of the positioning column 34, the bolt must be removed at this time), and drives the positioning column 34 to move toward the inside of the positioning hole 30 until the positioning column 34 finally abuts against the end rod 36; in the subsequent winding process, the two ends of the positioning column 34 are respectively limited by the end rod 36 and the support cover 46, and the position of the fixed positioning column 34 is stable.
[0093] When the positioning post 34 moves into the positioning hole 30, the inner wall of the inclined portion of the driving groove 35 acts on the drag reducing ball 33, and drives the drag reducing ball 33 and the positioning member 32 to move outward; then the positioning post 34 continues to move, so that the drag reducing ball 33 moves to the outer wall of the positioning post 34 (not in the inclined state), and at this time the first positioning portion 32a also moves to the outside of the support hole portion 31a, pressing the rewinding paper drum 5 tightly to prevent the rewinding paper drum 5 and the rewinding roller 1 from rotating relative to each other.
[0094] During subsequent use, since the drag-reducing ball 33 is pressed against the cylindrical surface of the positioning column 34, the positioning column 34 can be prevented from being subjected to horizontal forces. This can better prevent damage to the second support frame 3, the first adjustment frame 38, the second adjustment frame 39, etc., and ensure the service life of the equipment.
[0095] After winding is completed, the second elastic member 37 can drive the positioning post 34 outward under the elastic force to move, and the first positioning portions 32a are all accommodated in the support hole portion 31a, so that the rewinding paper roll 5 can be separated from the rewinding roller 1. Preferably, the positioning member 32 and the positioning post 34 are magnetically attracted to each other, so that all the first positioning portions 32a can be accommodated in the support hole portion 31a. Secondly, the width of the positioning member 32 is smaller than the width of the positioning post 34 at its minimum dimension. In this way, adjacent positioning members 32 do not affect each other during movement, so that the positioning of the rewinding paper roll 5 and the separation from the rewinding paper roll 5 can be carried out normally.
[0096] During the outward movement of the positioning column 34, the third positioning portion 32c moves into the driving groove 35 due to the action of gravity or gravity and magnetic force, and finally when the third positioning portion 32c hits the side of the driving groove 35 close to the first support frame 2, the positioning column 34 is affected by the third positioning portion 32c and cannot continue to move outward, and can only wait for the next use.
[0097] The positioning member 32 is U-shaped, so that its outer side has sufficient area to act on the rewinding paper drum 5, thereby enhancing the support and positioning effect on the rewinding paper drum 5. Secondly, the third positioning portion 32c is engaged with the anti-slip hole portion 31c, which can prevent the positioning member 32 from being detached from the rewinding roller 1. In addition, the U-shape of the positioning member 32 can also increase its strength and reduce damage to the rewinding roller 1.
[0098] When the rewinding motor 4 drives the rewinding roller 1 to rotate, the rewinding roller 1, the positioning column 34 and the support cover 46 can all rotate and rewind. Since the hinged rod 7 is connected to the middle part of the guide frame, the passive part 49 has a certain length. In this way, the strength of the passive part 49 can be improved by the consolidation part 51, and the passive part 49 can be used stably. When the pressing part 17b moves downward, when the piston disc 25 hits the termination ring 29, it means that the pressing part 17b has pressed the rewinding paper tube 5 to an appropriate force, preventing the pressing part 17b from applying excessive pressure to the rewinding paper tube 5, and the use effect is better. The piston disc 25 has a certain length, preferably 5-10 cm, so that the piston disc 25 and the piston cylinder can move stably relative to each other.
