Description

Technical Field

[0001] The present invention relates to the technical field of winding devices, and in particular to a winding device of a special paper gravure printing press and an operating method thereof. Background Art

[0002] At present, people use more and more paper. Due to the needs of different occasions, the demand for specialty paper is getting higher and higher, so the production equipment of specialty paper is becoming more and more perfect. The production process of specialty paper is roughly the same as that of general paper. In the final stage of production, a winding device is required to roll up the paper through a winding roller.

[0003] In the prior art, most winding devices require manual replacement of the winding roller, which results in high operator labor and low winding efficiency. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention aims to provide a winding device for a special paper gravure printing press and an operating method thereof to solve the above problems.

[0005] In view of this, the present invention provides a winding device for a special paper gravure printing press, comprising:

[0006] Two fixing plates are arranged on the ground at intervals, and two arc-shaped holes are arranged on the two fixing plates opposite to each other;

[0007] Drive the leather roller and rotate it between two fixed plates;

[0008] The supporting roller changing mechanism has two ends respectively arranged in two arc-shaped holes;

[0009] The roller placing mechanism is arranged between the two fixed plates and located above the supporting roller and roller changing mechanism;

[0010] and a roller unloading structure, which is arranged between the two fixed plates and is located on the side of the supporting roller changing mechanism away from the driving roller;

[0011] Among them, the roller placement mechanism is used to place several winding rollers and transport the winding rollers one by one to the supporting roller and roller changing mechanism. The supporting roller and roller changing mechanism is used to support the winding roller to collect special paper and transport the winding tube full of special paper to the unloading roller structure.

[0012] When the support roller changing mechanism moves back to its original position after unloading the winding roller, the roller placing mechanism will continue to lower the winding roller at the lowest end, so that the next winding roller can collect the special paper, thereby realizing automatic roller change, greatly reducing manual labor and improving work efficiency.

[0013] In the above technical solution, the support roller changing mechanism further includes:

[0014] Two supporting cylindrical blocks slide and rotate in the two arc-shaped holes respectively, and supporting grooves are provided on opposite sides of the two supporting cylindrical blocks;

[0015] Two supporting rebound structures, with fixed ends respectively arranged on the end walls of the two arc-shaped holes, and output ends respectively abutting against the outer walls of the two supporting cylindrical blocks;

[0016] and two rotation limiting structures, the movable ends of which are respectively arranged on opposite sides of the two fixed plates, and the connecting ends of which are connected to the two supporting fixed columns;

[0017] Among them, two limiting structures for stabilizing the winding of the winding roller are provided at one end of the two supporting cylindrical blocks facing away from each other, and the fixed end of the limiting structure is arranged on the side of the two supporting cylindrical blocks facing away from each other, and the output end passes through the supporting cylindrical block and extends to the winding roller. A flying knife structure for cutting special paper is provided on one side of the two supporting cylindrical blocks.

[0018] In this technical solution, through the setting of the support groove, the winding roller can be moved into the two support grooves, so that it can rotate but cannot move left and right. Through the setting of the support rebound structure, the support cylindrical block can rebound after the winding roller is unloaded. Through the setting of the rotation limiting structure, the support cylindrical block can be prevented from rotating at will, thereby preventing the winding roller from falling out and realizing the unloading of the winding roller. Through the setting of the limiting structure, the special paper will not deviate left and right on the winding roller. Through the setting of the flying knife structure, the special paper can be disconnected from the previous winding roller.

[0019] In the above technical solution, the support and rebound structure further includes:

[0020] A first elastic member is provided on the end wall of the arc-shaped hole facing the unloading roller structure;

[0021] an abutment block, one end of which is connected to an end opposite to the first elastic member, and the other end of which abuts against a side wall of the supporting cylindrical block;

[0022] and two limiting plates, respectively arranged on the two side walls of the arc-shaped hole;

[0023] Wherein, the outer side walls of the two supporting cylindrical blocks are provided with limiting ring grooves inserted into the limiting plates.

[0024] In this technical solution, when the thickness of the special paper collected by the winding roller becomes thicker, the winding roller will slowly be pushed away, so that the supporting cylindrical block slowly moves toward the first elastic member on the side of the unloading roller structure, and can only rotate slightly due to the restriction of the rotation limiting structure. At this time, the first elastic member is compressed. When the supporting cylindrical block unloads the winding roller without the influence of gravity, the first elastic member rebounds to support the cylindrical block, so that the supporting cylindrical block returns to its original position. The setting of the limit plate can prevent the supporting cylindrical block from moving left and right, and the setting of the resistance block can provide stable support.

[0025] In the above technical solution, the rotation limiting structure further includes:

[0026] A first limiting rod is provided on a side opposite to the supporting cylindrical block;

[0027] A second limiting rod, one end of which is connected to the first limiting rod and the other end of which slides in the fixing plate;

[0028] A first rotating motor is provided on one side opposite to the two supporting cylindrical blocks;

[0029] and a swing rod connected to the output end of the first rotating motor;

[0030] The fixing plate is provided with a rotation limiting groove for the second limiting rod to slide into, and the end wall of the rotation limiting groove is provided with a roller unloading groove for the second limiting rod to move into. A second elastic member is provided on the side wall of the roller unloading groove at one end away from the rotation limiting groove, and the second elastic member is provided with a pushing block.

[0031] In the technical solution, firstly, the supporting cylinder block can only move according to the arc-shaped hole, and slowly moves along the arc-shaped hole when being pushed open. Due to the movement of the supporting cylinder block, the first limiting rod also moves and drives the second limiting rod to move. Since the second limiting rod is limited by the limiting rotation groove, the supporting cylinder block cannot rotate randomly and can only slightly rotate according to the limitation of the limiting rotation groove. When the second limiting rod moves to the junction of the limiting rotation groove and the unloading roller groove, the winding roller is full of winding, the first rotating motor is started to drive the swing rod to rotate, so that the swing rod drives the second limiting rod to move into the unloading roller groove. Since the unloading roller groove is an arc-shaped groove arranged at the center of the supporting cylinder block at this time, the supporting cylinder block rotates to make the supporting groove rotate to the unloading roller structure angle. At this time, the winding roller slowly descends to the unloading roller structure under the influence of gravity. When the winding roller is unloaded, the first spring does not rebound to support the cylinder block at the first time. Due to the limitation of the second limiting rod in the unloading roller groove, the rotating motor slowly rotates back at this time, and the second elastic member slowly pushes back the push-out block so that the second limiting rod is pushed out. At this time, the first elastic member can rebound to support the cylinder block to return to the original position.

[0032] In the above technical solution, the limiting structure further comprises:

[0033] The driving disc is rotationally connected to one end of the two supporting cylinder blocks away from each other, and a plurality of arc-shaped driving grooves are arranged around the center axis of the driving disc at one end of the supporting cylinder block.

[0034] A plurality of moving rods are slidably arranged in the arc-shaped driving grooves at one end and penetrate the supporting cylinder block at the other end.

[0035] A plurality of limiting strip blocks are arranged on the side wall of the moving rod away from the driving disc.

[0036] And a driving structure is arranged on the outer side wall of the supporting cylinder block, and the output end is arranged on the outer side wall of the driving disc.

[0037] Wherein, a plurality of strip-shaped limiting holes are arranged around the center axis of the supporting cylinder block on the end wall of the supporting cylinder block. When the driving structure drives the driving disc to rotate, the moving rod moves in the strip-shaped limiting hole, so that a plurality of limiting strip blocks are close to each other or apart from each other. The bottom side wall of the arc-shaped driving groove is provided with a limiting groove, and the moving rod is provided with a limiting disc sliding in the limiting groove at one end of the arc-shaped driving groove.

[0038] In the present technical solution, the arc-shaped driving groove can be processed by setting the driving disk, and the moving rod can be restricted in movement within the arc-shaped driving groove by setting the moving rod. The limiting strip block can be installed by setting the moving rod. Through the cooperation of the strip limiting hole and the arc-shaped driving groove, when the driving disk rotates, the moving rod can simultaneously move toward the length direction of the strip limiting hole, thereby achieving the goal of simultaneously approaching the outer wall of the winding roller or simultaneously moving away from the outer wall of the winding roller, and finally achieving the goal of limiting the special paper of different thicknesses when the thickness of the special paper is thickened, solving the traditional fixation and achieving the limit without being installed on the winding roller. The setting of the limiting groove and the limiting disk can prevent the moving rod from slipping out, and the setting of the driving structure can enable the driving disk to rotate.

[0039] In the above technical solution, the driving structure further includes:

[0040] A driving motor, with a fixed end disposed on the side wall of the supporting cylindrical block and an output end extending toward the driving disk;

[0041] Transmission teeth are arranged on the outer side wall of the driving disc;

[0042] and a driving gear, which is arranged on the output end of the driving motor;

[0043] Wherein, the transmission teeth are used to drive the rotating teeth to rotate.

[0044] In this technical solution, the drive motor is provided to rotate the drive gear, thereby causing the drive gear to rotate the transmission teeth, and finally causing the drive disc to rotate.

[0045] In the above technical solution, the roller placing mechanism further includes:

[0046] Two first placement rods are arranged on opposite sides of the two fixed plates, with one end of the first placement rod being located above the support roller changing mechanism and the other end extending away from the top of the fixed plate;

[0047] Two second placement rods are arranged on opposite sides of the two fixed plates, with one end of the first placement rod being located above the support roller and roller changing mechanism and the other end extending away from the top of the fixed plate, and the second placement rods are spaced apart from the first placement rods;

[0048] and two lower roller structures, respectively disposed on the first placement rod and the second placement rod;

[0049] Among them, a plurality of winding rollers are placed between the first placement rod and the second placement rod, and the lower roller structure is used to move the winding rollers one by one to the support roller and roller changing mechanism.

[0050] In this technical solution, a plurality of winding rollers can be placed by the cooperation of the first placing rod and the second placing rod, and the winding rollers can be lowered one by one by the setting of the lower roller structure.

[0051] In the above technical solution, the lower roller structure further includes:

[0052] A hydraulic cylinder, wherein the fixed end is arranged on the side wall of the second placement rod facing away from the first placement rod, and the output end passes through the second placement rod;

[0053] Two second rotating motors are respectively arranged on the side walls of the first placing rod and the second placing rod facing away from the fixed plate, and the second rotating motors are located below the output end of the hydraulic cylinder;

[0054] and two tow rods, respectively provided on the output ends of the two second rotating motors;

[0055] Among them, the output ends of the two second rotating motors are at different distances, so that the two drag rods are initially arranged crosswise. When the output end of the hydraulic cylinder retracts, the winding roller moves into the cross position of the two drag rods, so that when the two second rotating motors rotate, the winding roller slowly descends to the support roller and roller changing mechanism.

[0056] In this technical solution, when the winding roller needs to be lowered, the output end of the hydraulic cylinder retracts. At this time, the winding roller descends to the intersection of the two drag rods. At this time, the output end of the second hydraulic cylinder extends to prevent more winding rollers from descending. Then the second rotating motor is started to slowly lower the intersection position of the drag rods, so that the winding roller slowly descends. When it descends to a certain position, the two drag rods are opened, so that the winding roller falls onto the support roller and roller changing mechanism.

[0057] In the above technical solution, the following steps are further included:

[0058] S1: First, place several winding rollers on the roller placement mechanism, and then place the specialty paper on top of the rollers:

[0059] S2: Start the roller placement mechanism, which moves the lowest winding roller to the support roller changing mechanism. The support roller changing mechanism starts the top roller, which drives the top roller to drive the winding roller to rotate in the opposite direction to collect the special paper.

[0060] S3: When the winding roller is full of special paper, the support roller changing mechanism moves the winding roller to the unloading roller structure and cuts the special paper, while driving the top roller to stop rotating;

[0061] S4: When the support roller and roller changing mechanism moves back to the original position after unloading the winding roller, the roller placing mechanism continues to lower the lowest winding roller, so that the winding roller continues to collect the special paper.

[0062] In this technical solution, through the setting of S1, it is possible to realize automatic replacement of rollers for standby, and connect the special paper when the winding roller rotates. Through the setting of S2, it is possible to automatically lower the winding roller and collect the special paper by the winding roller. Through the setting of S3, the special paper can be left on the driving roller after the winding roller is unloaded, so that the next winding roller can collect the special paper. Through the setting of S4, the next winding roller can collect the special paper, thus realizing automatic roller replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0073] Embodiment 1:

[0074] The embodiment provides a winding device of a special paper intaglio printing machine, which comprises:

[0075] Two fixed plates 1 are arranged on the ground at intervals, and two arc-shaped holes 2 are arranged on the two fixed plates 1 oppositely;

[0076] A driving leather roller 3 is rotatably connected between the two fixed plates 1;

[0077] A supporting roller changing mechanism is arranged in the two arc-shaped holes 2 at two ends, respectively;

[0078] A roller placing mechanism is arranged between the two fixed plates 1 and above the supporting roller changing mechanism;

[0079] And a roller unloading structure is arranged between the two fixed plates 1, and the roller unloading structure is located on the side of the supporting roller changing mechanism away from the driving leather roller 3;

[0080] The roller placing mechanism is used for placing a plurality of winding rollers and conveying the winding rollers to the supporting roller changing mechanism one by one, the supporting roller changing mechanism is used for supporting the winding rollers to collect special paper and conveying the winding tube full of special paper to the roller unloading structure;

[0081] When the support roller changing mechanism moves back to its original position after unloading the winding roller, the roller placing mechanism will continue to lower the winding roller at the lowest end, so that the next winding roller can collect special paper, thereby realizing automatic roller change, greatly reducing manual labor and improving work efficiency.

[0082] Example 2:

[0083] In this embodiment, in addition to the structural features of the aforementioned embodiment, the support roller changing mechanism further includes:

[0084] Two supporting cylindrical blocks 4 slide and rotate in the two arc-shaped holes 2 respectively, and supporting grooves are provided on opposite sides of the two supporting cylindrical blocks 4;

[0085] Two supporting rebound structures, the fixed ends of which are respectively arranged on the end walls of the two arc-shaped holes 2, and the output ends respectively abut against the outer walls of the two supporting cylindrical blocks 4;

[0086] and two rotation limiting structures, the movable ends of which are respectively arranged on opposite sides of the two fixed plates 1, and the connecting ends are connected to the two supporting fixed columns;

[0087] Among them, two limiting structures for stabilizing the winding of the winding roller are provided at one end of the two supporting cylindrical blocks 4 facing away from each other. The fixed end of the limiting structure is provided on the side of the two supporting cylindrical blocks 4 facing away from each other, and the output end passes through the supporting cylindrical block 4 and extends to the winding roller. A flying knife structure 5 for cutting the special paper is provided on one side of the two supporting cylindrical blocks 4;

[0088] By setting the support grooves, the winding roller can be moved into the two support grooves, so that it can rotate but cannot move left and right. By setting the support rebound structure, the support cylindrical block 4 can rebound after the winding roller is unloaded. By setting the rotation limiting structure, the support cylindrical block 4 can be prevented from rotating at will, thereby preventing the winding roller from falling out and realizing the unloading of the winding roller. By setting the limiting structure, the special paper will not deviate left and right on the winding roller. By setting the flying knife structure 5, the special paper can be disconnected from the previous winding roller.

[0089] Example 3:

[0090] In this embodiment, in addition to the structural features of the aforementioned embodiment, the support and rebound structure further includes:

[0091] A first elastic member 6 is provided on the end wall of the arc-shaped hole 2 facing the unloading roller structure;

[0092] The abutment block 7 has one end connected to the opposite end of the first elastic member 6 and the other end abutting against the side wall of the supporting cylindrical block 4;

[0093] and two limiting plates 8, respectively provided on the two side walls of the arc-shaped hole 2;

[0094] The outer side walls of the two supporting cylindrical blocks 4 are provided with limiting ring grooves 9 inserted into the limiting plates 8;

[0095] When the thickness of the special paper collected by the winding roller becomes thicker, the winding roller will slowly be pushed away, so that the supporting cylindrical block 4 slowly moves toward the first elastic member 6 on the side of the unloading roller structure, and can only rotate slightly due to the restriction of the rotation limiting structure. At this time, the first elastic member 6 is compressed. When the supporting cylindrical block 4 removes the winding roller without the influence of gravity, the first elastic member 6 rebounds to support the cylindrical block 4, so that the supporting cylindrical block 4 returns to its original position. The setting of the limit plate 8 can prevent the supporting cylindrical block 4 from moving left and right, and the setting of the resistance block 7 can provide stable support.

[0096] Example 4:

[0097] In this embodiment, in addition to the structural features of the aforementioned embodiment, the rotation limiting structure further includes:

[0098] A first limiting rod 10 is provided on a side opposite to the supporting cylindrical block 4;

[0099] A second limiting rod 11, one end of which is connected to the first limiting rod 10 and the other end of which slides in the fixing plate 1;

[0100] The first rotating motor 12 is provided on the opposite side of the two supporting cylindrical blocks 4;

[0101] and a swing rod 13 connected to the output end of the first rotating motor 12;

[0102] The fixed plate 1 is provided with a rotation-limiting groove 14 for the second limiting rod 11 to slide into, and an end wall of the rotation-limiting groove 14 is provided with a roller unloading groove 15 for the second limiting rod 11 to move into. A second elastic member 16 is provided on the side wall of the roller unloading groove 15 facing away from the rotation-limiting groove 14, and the second elastic member 16 is provided with a push-out block 17;

[0103] First, the supporting cylindrical block 4 can only move according to the arc hole 2. When it is pushed open, it slowly moves along the arc hole 2. Due to the movement of the supporting cylindrical block 4, the first limiting rod 10 also has to move and drive the second limiting rod 11 to move. Since the second limiting rod 11 is restricted by the rotation limiting groove 14, the supporting cylindrical block 4 will not rotate arbitrarily and can only rotate slightly according to the restriction of the rotation limiting groove 14. When the second limiting rod 11 moves to the junction of the rotation limiting groove 14 and the unloading roller groove 15, the winding roller is fully wound, the first rotating motor 12 is started, and the rocker arm 13 is driven to rotate, thereby the rocker arm 13 drives the second limiting rod 11 to rotate. The positioning rod 11 moves into the unloading roller groove 15. Since the unloading roller groove 15 supports the arc groove set in the center of the cylindrical block 4 at this time, it supports the cylindrical block 4 to rotate, so that the support groove rotates to the unloading roller structure angle. At this time, the winding roller is affected by gravity and slowly moves down to the unloading roller structure. When the winding roller is unloaded, the first spring will not rebound to support the cylindrical block 4 at the first time. Since the second limiting rod 11 is restricted in the unloading roller groove 15, the rotating motor slowly rotates at this time, and the second elastic member 16 slowly pushes back the ejection block 17 so that the second limiting rod 11 is pushed out. At this time, the first elastic member 6 can rebound to support the cylindrical block 4 to return to its original position.

[0104] Example 5:

[0105] In this embodiment, in addition to the structural features of the aforementioned embodiment, the limiting structure further includes:

[0106] A driving disc 18 is rotatably connected to the ends of the two supporting cylindrical blocks 4 that are away from each other. The end of the driving disc 18 facing the supporting cylindrical block 4 is provided with a plurality of arc-shaped driving grooves 20 circumferentially arranged around the central axis of the driving disc 18.

[0108] A plurality of limiting strip blocks 21 are respectively provided on the side wall of the end of the moving rod 19 away from the driving disk 18;

[0109] and a driving structure, wherein the fixed end is arranged on the outer wall of the supporting cylindrical block 4, and the output end is arranged on the outer wall of the driving disk 18;

[0110] Among them, a plurality of strip-shaped limiting holes 27 are provided on the end wall of the supporting cylindrical block 4 in a circumferential direction with respect to the central axis of the supporting cylindrical block 4. When the driving structure drives the driving disk 18 to rotate, the moving rod 19 moves into the strip-shaped limiting hole 27, thereby causing the plurality of limiting strip blocks 21 to move closer to or apart from each other. A limiting groove 22 is provided on the side wall of the bottom of the arc-shaped driving groove 20. A limiting disk 23 is provided on one end of the moving rod 19 facing the arc-shaped driving groove 20 and sliding in the limiting groove 22.

[0111] By setting the driving disk 18, the arc-shaped driving groove 20 can be processed. By setting the arc-shaped driving groove 20, the moving rod 19 can be restricted in movement within the arc-shaped driving groove 20. By setting the moving rod 19, the limiting strip block 21 can be installed. By cooperating with the strip limiting hole 27 and the arc-shaped driving groove 20, when the driving disk 18 rotates, the moving rod 19 can simultaneously move toward the length direction of the strip limiting hole 27, thereby achieving the goal of simultaneously approaching the outer wall of the winding roller or simultaneously moving away from the outer wall of the winding roller, and finally achieving the goal of limiting the special paper of different thicknesses when the thickness of the special paper is thickened, solving the traditional fixation and achieving the limit without being installed on the winding roller. By setting the limiting groove 22 and the limiting disk 23, the moving rod 19 can be prevented from slipping out. By setting the driving structure, the driving disk 18 can be rotated.

[0114] The driving motor 24 has a fixed end disposed on the side wall of the supporting cylindrical block 4 and an output end extending toward the driving disk 18;

[0115] Transmission gear 25, provided on the outer side wall of the driving disc 18;

[0116] and a driving gear 26, which is provided on the output end of the driving motor 24;

[0117] Wherein, the transmission teeth 25 are used to drive the rotating teeth to rotate;

[0118] By setting the driving motor 24 , the driving gear 26 can be rotated, so that the driving gear 26 drives the transmission gear 25 to rotate, and finally the driving disc 18 is rotated.

[0119] Example 7:

[0120] In this embodiment, in addition to the structural features of the aforementioned embodiment, the roller placement mechanism further includes:

[0121] Two first placement rods 28 are arranged on opposite sides of the two fixed plates 1, and one end of the first placement rod 28 is located above the support roller and roller changing mechanism, and the other end extends away from the top of the fixed plate 1;

[0122] Two second placement rods 29 are arranged on opposite sides of the two fixed plates 1, and one end of the first placement rod 28 is located above the support roller and roller changing mechanism, and the other end extends away from the top of the fixed plate 1. The second placement rod 29 is spaced apart from the first placement rod 28;

[0123] And two lower roller structures are arranged on the first placing rod 28 and the second placing rod 29 respectively.

[0124] The first placing rod 28 and the second placing rod 29 are used for placing a plurality of winding rollers, and the lower roller structure is used for moving the winding rollers to the supporting roller changing mechanism one by one.

[0125] Through the cooperation of the first placing rod 28 and the second placing rod 29, the plurality of winding rollers can be placed, and through the arrangement of the lower roller structure, the winding rollers can be lowered one by one.
