Description

Technical Field

[0001] The present application relates to the technical field of white cardboard rolling, and in particular to a rolling device for white cardboard production. Background Art

[0002] White cardboard has a relatively uniform fiber structure, the surface layer has filler and rubber components, and the surface is coated with a certain coating, and is calendered or embossed. It is mainly used as printing paper for packaging and decoration.

[0003] The production process of white cardboard includes pulping-papermaking-forming-drying and post-processing steps. After production is completed, the paper needs to be rolled up and then transported to different workshops for die-cutting, finally forming paper of different sizes that we use in daily life.

[0004] Common equipment for rolling up white cardboard includes a frame, a winding roller rotatably arranged on the frame, and a guide roller rotatably arranged on the frame. The feed port of the entire frame corresponds to the discharge port of the preceding equipment. After the preceding processing, the paper enters the guide roller and is rolled up under the action of the guide roller and the winding roller.

[0005] Regarding the above-mentioned related technologies, since the rotation speed of the winding roller is often constant, and the previous production process often fluctuates due to the mismatch of production speed, the guide roller often has a certain tensioning effect. However, when the production speed does not match and fluctuates, wrinkles are likely to appear on the sides of the paper, and folding or warping of the edges are likely to occur during winding, affecting the winding quality and subsequent forming quality. Utility Model Content

[0006] In order to reduce the folding and warping of edges during winding and improve the winding quality of white cardboard, the present application provides a winding device for white cardboard production.

[0007] The present application provides a winding device for white cardboard production using the following technical solution:

[0008] The camming device according to claim 1, wherein the roller is arranged on the frame to move relative to the rollers, and the rollers are arranged on the frame to move relative to the rollers.

[0009] By adopting the above technical solution, during normal winding, the white card paper after production is fed into the winding roller through the auxiliary roller for winding. When the speed mismatch occurs in the previous production sequence causing fluctuations in the conveying, the elastically arranged auxiliary roller provides a buffer space for the conveying of the white card paper, thereby reducing the breakage caused by excessive tension of the paper and the wrinkles caused by excessive looseness.

[0010] At the same time, by setting up an inclined smoothing roller, when the white cardboard is fed into the winding roller, the smoothing roller is set to rotate. Since the roller circumference of the smoothing roller is inclined, the edges of the white cardboard are clamped when the smoothing roller rotates. When the smoothing roller rotates, the inclined smoothing roller applies a force to the edges of the white cardboard to keep the edges of the white cardboard taut, thereby making it difficult for the edges of the white cardboard to be folded, and at the same time making it difficult for the middle part of the white cardboard to be wrinkled, thereby improving the quality of the white cardboard when it is rolled up.

[0011] Two sets of leveling rollers are provided to clamp and level the opposite sides of the white card paper respectively, thereby improving the winding quality of the white card paper.

[0012] Optionally, the leveling component also includes a leveling plate arranged on the frame, the leveling plate is provided with a leveling opening for supplying white cardboard, the leveling roller is provided on the side of the leveling plate close to the winding roller, the leveling plate is hollow, and air outlet holes are provided on the two opposite inner walls of the leveling opening, the air outlet holes are symmetrically provided in two groups, and the air outlet holes are arranged obliquely toward both sides, and the leveling plate is also provided with a pressure member for supplying air to the air outlet holes.

[0013] By adopting the above technical scheme, when the white card paper is rolled up and conveyed, the white card paper first passes through the leveling port of the leveling plate before entering the leveling roller. At this time, air is supplied to the air outlet through the pressure piece. At this time, the air flow through the air outlet blows on the surface of the white card paper, and blows off the impurities that fall on the surface of the white card paper while blowing on the surface of the white card paper, so that the ripples or wrinkles on the white card paper are spread out toward both sides, which is convenient for the subsequent leveling roller to level the edges of the white card paper.

[0014] At the same time, by setting up the leveling plate and opening the leveling port, the direction of the white card paper entering the leveling roller due to the fluctuation of the previous process is reduced, and the leveling roller can achieve stable leveling of the white card paper.

[0015] Optionally, the smoothing plate is rotatably arranged on the frame, and the frame is also provided with a synchronizing member for synchronizing the sliding of the auxiliary roller with the rotation of the smoothing plate.

[0016] By adopting the above technical scheme, when the transmission speed of the white cardboard fluctuates, it is easy to cause scratches between the white cardboard transported to the leveling plate and the sides of the leveling mouth, affecting the surface quality of the white cardboard. By rotating the leveling plate and the synchronous parts, when the auxiliary roller slides to provide tension to the white cardboard, the leveling plate is driven to rotate under the action of the synchronous parts, thereby making it easier for the white cardboard to enter the leveling mouth and improving the surface quality of the white cardboard.

[0017] Optionally, the driving member includes a synchronous bevel gear provided on the rotating shaft of the smoothing roller, and the synchronous bevel gears on two smoothing rollers in the same group are meshed with each other.

[0018] By adopting the above technical solution, when a group of smoothing rollers needs to be driven to rotate, the technician only needs to connect an external power source to the rotating shaft of one of the smoothing rollers, and the other smoothing roller can be driven to rotate under the action of the synchronous bevel gear. The two smoothing rollers rotate in opposite directions, thereby achieving stable smoothing of the edges of white cardboard.

[0019] Optionally, the synchronization component includes a mounting frame provided on the frame and a synchronization rod rotatably provided on the frame, the sorting plate is rotatably provided on the mounting frame, the auxiliary roller is elastically provided on the mounting frame, a first positioning block is provided at the rotating shaft of the auxiliary roller, a second positioning block is provided on the sorting plate, the first positioning block and the second positioning block are both movably fitted with the synchronization rod, and a return member is provided at the rotating shaft of the sorting plate.

[0020] By adopting the above technical solution, when fluctuations occur in the transportation process of the white cardboard, the tensioning auxiliary roller slides under the action of the tensioning force. During the sliding of the auxiliary roller, the first positioning block slides accordingly, and the first positioning block presses against the synchronization rod, driving the synchronization rod to rotate. The synchronization rod presses against the second positioning block, thereby causing the straightening plate to rotate, so that the straightening port of the straightening plate is always facing the conveying direction of the white cardboard, so that the white cardboard is not easily scratched by the side wall of the straightening port, thereby improving the surface quality of the white cardboard.

[0021] Optionally, the opening width of the leveling port on a side close to the feeding direction is greater than the opening width on a side away from the feeding direction, and the width inside the leveling port presents a smooth transition.

[0022] By adopting the above technical scheme, the leveling opening is set in the form of a smooth transition from large to small opening, which makes it easy for the white cardboard after production to enter the leveling plate for leveling and transportation, further improving the surface quality of the white cardboard surface, and at the same time facilitating the limiting of the fluctuating white cardboard, so that the white cardboard entering between the leveling rollers remains stable, thereby achieving stable leveling of the edges of the white cardboard by the leveling rollers.

[0023] Optionally, an electrostatic roller is further provided on the frame, and the electrostatic roller is arranged on the side of the auxiliary roller close to the feeding direction. An electrostatic eliminator is provided on the end side of the electrostatic roller, and bristles are provided on the outer side of the electrostatic roller, and the bristles are tightly fitted against the surface of the white cardboard.

[0024] By adopting the above technical solution, the electrostatic roller and the electrostatic eliminator are set up to first remove static electricity from the surface of the white cardboard before rolling and flattening, thereby reducing dust adsorbed on the surface of the white cardboard due to static electricity during transportation, thereby reducing rolling and folding caused by the adhesion of dust and impurities. At the same time, the white cardboard after the static electricity is removed is not easy to produce friction between the white cardboards when rolling.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. By setting the leveling rollers arranged in an inclined manner, the edges of the white cardboard are leveled and pressed tightly during the transportation process, thereby reducing the wrinkles of the white cardboard when it is rolled up and improving the surface quality of the white cardboard when it is rolled up;

[0027] 2. Through the set leveling plate, the leveling opening and the air outlet holes on the leveling plate, when the white card paper is transported, air is blown at the air outlet holes to blow the surface of the white card paper, thereby reducing the dust residue on the surface of the white card paper, and at the same time, the surface of the white card paper is smoothed to reduce the wrinkles of the white card paper;

[0028] 3. Through the setting of the synchronization rod, the first positioning block and the second positioning block, when the auxiliary roller fluctuates with the transportation of the white card paper, the auxiliary roller slides up and down at this time, driving the first positioning block to press against the synchronization rod, so that the synchronization rod presses against the second positioning block to drive the flat plate to rotate, so that the leveling port on the flat plate is consistent with the transportation direction of the white card paper, reducing the scratches caused by the white card paper and the side wall of the leveling port.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-3 This application is described in further detail.

[0034] The present application embodiment discloses a winding device for white cardboard production. Figure 1 A winding device for white cardboard production includes a frame 1 fixed on the ground and a winding roller 11 rotatably arranged on the frame 1, a winding motor for rotating and driving the winding roller 11 is provided on the frame 1, an auxiliary roller 2 is rotatably arranged on the frame 1 on the side of the winding roller 11 close to the feeding direction, the rotation axis of the auxiliary roller 2 is horizontal, and the rotating shaft of the auxiliary roller 2 is slidably arranged on the frame 1, and the sliding direction of the rotating shaft of the auxiliary roller 2 is consistent with the height direction of the frame 1, and a leveling component 3 for leveling the surface of the white cardboard is also provided on the frame 1.

[0035] Reference Figure 1 and Figure 2The leveling assembly 3 includes a leveling roller 31 rotatably arranged on the frame 1 and a driving member 32 for driving the leveling roller 31 to rotate. The leveling roller 31 is arranged between the auxiliary roller 2 and the winding roller 11. The rotation axis of the leveling roller 31 is arranged at an angle to the rotation axis of the auxiliary roller 2. The leveling roller 31 is provided with two groups and the two groups of leveling rollers 31 are arranged symmetrically. Each group of leveling rollers 31 includes two leveling rollers 31 arranged at an angle to each other. The two leveling rollers 31 are arranged along the height direction of the frame 1. The two sets of smoothing rollers 31 are arranged at intervals, and the roller circumference is inclined. The diameter of the side where the two sets of smoothing rollers 31 are close to each other is narrower than the diameter of the side where they are far away from each other. A gap is left between the two sets of smoothing rollers 31 for white cardboard to pass through. That is, when the two smoothing rollers 31 rotate to clamp the sides of the white cardboard, due to the inclination of the rotating axes of the two smoothing rollers 31, when the smoothing rollers 31 rotate, the sides of the white cardboard are always kept extended, so that the sides of the white cardboard are not easy to fold, thereby improving the production quality of the white cardboard.

[0036] In order to realize the synchronous driving of the two smoothing rollers 31, the driving member 32 includes a synchronous bevel gear 321 rotatably arranged on the rotating shaft of the smoothing roller 31. The two synchronous bevel gears 321 in the same group are meshed with each other. A driving motor is provided on the frame 1 corresponding to each group of smoothing rollers 31. The rotating shaft of one smoothing roller 31 in the same group of two smoothing rollers 31 is fixed to the output end of the driving motor, and the two driving motors rotate synchronously. When one driving motor is working, it drives one smoothing roller 31 to rotate. When one smoothing roller 31 rotates, it drives one synchronous bevel gear 321 to rotate. When one synchronous bevel gear 321 rotates, it drives the other synchronous bevel gear 321 to rotate, thereby realizing the smoothing operation of the two smoothing rollers 31 on the sides of the white cardboard.

[0037] Reference Figure 1 and Figure 2 The leveling component 3 also includes a leveling plate 33 arranged on the mounting frame 13. The leveling plate 33 is arranged between the auxiliary roller 2 and the winding roller 11. A leveling port 34 for the white card paper to pass through is opened on the leveling plate 33. The interior of the leveling plate 33 is hollow, and the leveling port 34 is parallel to the surface of the white card paper. Air outlet holes are opened on the two opposite inner walls. There are two groups of air outlet holes, and the two groups of air outlet holes are symmetrically arranged. The air outlet holes are inclined toward the side of the white card paper. The frame 1 is also provided with a pressurizing member 35 for supplying air to the air outlet hole. In this application, the pressurizing member 35 is an air pump 351 fixed on the frame 1.

[0038] A sliding groove is opened on the mounting frame 13, and the rotating shaft of the auxiliary roller 2 is slidably set in the sliding groove. The opening direction of the sliding groove is consistent with the height direction of the frame 1. An auxiliary spring 21 is fixedly connected in the sliding groove, and one end of the auxiliary spring 21 away from the bottom wall of the sliding groove is fixedly connected to the rotating shaft of the auxiliary roller 2.

[0039] At the same time, the opening of the leveling opening 34 on the side close to the auxiliary roller 2 is larger than the opening on the side close to the winding roller 11 , and the opening of the leveling opening 34 has a smooth transition.

[0040] When the entire white cardboard fluctuates, under the elastic action of the auxiliary spring 21, the transportation of the white cardboard will fluctuate with tension. At this time, the larger opening of the leveling mouth 34 facilitates the white cardboard to enter and pass through the leveling mouth 34, reducing the friction between the inner wall of the leveling mouth 34 and the white cardboard, thereby improving the surface quality of the white cardboard.

[0041] At the same time, the air blowing holes provided at the leveling opening 34 blow air outwards under the action of the pressure member 35 to blow the edges of the white card paper and reduce the folding of the edges of the white card paper.

[0042] In order to further realize the synchronous adjustment of the auxiliary roller 2 and the sorting plate 33, a synchronous member 36 is provided on the mounting frame 13, and the synchronous member 36 includes a synchronous rod 361 rotatably connected to the mounting frame 13, and the rotation axis of the synchronous rod 361 is horizontal and perpendicular to the conveying direction of the white card paper. At the same time, the sorting plate 33 is rotatably arranged on the mounting frame 13, and a second positioning block 363 is provided at the bottom side of the sorting plate 33 away from the auxiliary roller 2. The first positioning block 362 is fixedly connected to the rotating shaft of the auxiliary roller 2, and one end of the synchronous rod 361 is tightly fitted with the first positioning block 362, and the other end of the synchronous rod 361 is tightly fitted with the second positioning block The blocks 363 are tightly fitted together, and a return member 37 is provided at the rotating shaft of the straightening plate 33. In the present application, the return member 37 includes a torsion spring 371 fixed at the rotating shaft of the straightening plate 33. When the white card paper fluctuates, the auxiliary roller 2 slides under the tension fluctuation of the white card paper, and the rotating shaft of the auxiliary roller 2 slides in the sliding groove. The first positioning block 362 presses against the synchronization rod 361 to rotate, and the synchronization rod 361 presses against the second positioning block 363 to rotate the straightening plate 33, so that the direction of the straightening plate 33 is always consistent with the transportation direction of the white card paper, so that the white card paper can always stably enter between the two sets of straightening rollers 31 for straightening.

[0043] At the same time, when the white card paper is rolled up, static electricity often exists on the surface of the white card paper. During the rolling process, the paper surface of the white card paper is easily adsorbed due to static electricity, adsorbing dust or causing the paper surface of the white card paper to adsorb to the paper surface, thereby folding, affecting the rolling quality of the white card paper. In order to solve this problem, the auxiliary roller 2 is further rotated on the frame 1 on the side away from the winding roller 11, and the bottom side of the static roller 38 is in contact with the paper surface of the white card paper. At the same time, a static eliminator 381 is provided on the end side of the static roller 38, and a brush 382 is provided on the outer peripheral wall of the static roller 38. The brush 382 is electrically connected to the static eliminator 381. The set static roller 38 cooperates with the auxiliary roller 2, so that the white card paper is always in contact with the auxiliary roller 2 during transportation, so that the transportation of the white card paper is stable. At the same time, the static eliminator 381 and the brush 382 are provided to eliminate the static electricity on the surface of the white card paper, which not only reduces the adsorption of dust on the surface of the white card paper, but also reduces the folding generated on the surface of the white card paper.

[0044] The implementation principle of a winding device for white cardboard production in an embodiment of the present application is as follows: when the white cardboard is transported to the winding stage, the white cardboard passes through an electrostatic roller 38, and static electricity is removed from the surface of the white cardboard under the action of an electrostatic eliminator 381 and a brush 382, ​​thereby reducing the adhesion of dust on the surface of the white cardboard.

[0045] When the white card paper is conveyed to the auxiliary roller 2, the auxiliary roller 2 at this time slides elastically under the action of the white card paper's pressure, so that the white card paper always remains tensioned during transportation. At the same time, during the sliding process of the auxiliary roller 2, the first positioning block 362 presses against the synchronization rod 361 to rotate, and the synchronization rod 361 presses against the second positioning block 363 to drive the flat plate 33 to rotate, thereby realizing the rotation of the flat plate 33, so that the white card paper enters the flattening port 34 for flattening. At the same time, the pressure member 35 and the blowing hole are set, and the pressure member 35 makes the blowing hole blow air outward, so as to realize the blowing and flattening operation on the side of the white card paper, reduce the folding of the white card paper during the winding process, and improve the winding quality of the white card paper.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
