Description

Technical Field

[0001] This application relates to the technical field of winding and wrinkle removal, and particularly to a winding and wrinkle removal mechanism and a winding device. Background Art

[0002] Materials such as films, papers, textiles, etc. need to be wound to complete packaging. These materials are tangent to the winding roller, and the tangent point is the feeding tangent point position. During the winding process of the material to be wound, a wrinkle removal device is usually required to eliminate the wrinkles or folds generated during the winding process.

[0004] However, whether the flattening roller is directly pressed on the winding roller through a telescopic mechanism or the position of the flattening roller is adjusted through a swing arm, the feeding tangent point position will change due to the increase in the thickness of the material roll, and the wrinkles cannot be flattened and removed at the feeding tangent point position all the time, resulting in poor wrinkle removal effect.

[0041] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0043] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "mount", "connect", and "couple" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0044] Materials such as films, papers, textiles, etc. need to be wound up for packing. These materials are tangent to the winding roller, and the tangent point is the position of the feeding tangent point. During the winding process of the material to be wound, a wrinkle-removing device is usually required to eliminate the wrinkles or folds generated during the winding process of the material.

[0045] In the related art, the wrinkle-removing device usually directly presses a telescopic flattening roller on the winding roller, or drives the flattening roller to change its position through a swing arm and presses the flattening roller on the winding roller.

[0046] However, whether the flattening roller is directly pressed against the winding roller through a telescopic mechanism or the position of the flattening roller is adjusted through a swing arm, the feeding tangent point position will change due to the increase in the thickness of the coil, resulting in the inability to always flatten and remove wrinkles at the feeding tangent point position, thus leading to poor wrinkle removal effect. Therefore, the present application provides a winding wrinkle removal mechanism and a winding device to solve or improve the problem of poor wrinkle removal effect.

[0047] The following combines Figures 1 to 6 to describe the embodiments of the present application.

[0048] According to an embodiment of the present application, on the one hand, a winding wrinkle removal mechanism is provided, including: a mounting frame 1 and a wrinkle removal roller 3.

[0049] Specifically, as Figure 1 and Figure 4 shown, a guiding part 2 is arranged on the mounting frame 1, and the wrinkle removal roller 3 is slidably connected to the guiding part 2;

[0050] During the winding operation, as Figure 3 shown, the wrinkle removal roller 3 slides along the guiding track of the guiding part 2, and the wrinkle removal roller 3 can always rollingly abut against the feeding tangent point position of the winding roller 5.

[0051] In this embodiment, as Figure 3 and Figure 6 shown, the wrinkle removal roller 3 is slidably connected to the guiding part 2. As the thickness of the coil 6 increases, the change trajectory of the feeding tangent point position of the winding roller 5 is the same as the guiding track of the guiding part 2, which can ensure that during the process of the increase in the thickness of the coil 6 on the winding roller 5, the wrinkle removal roller 3 always rollingly abuts against the feeding tangent point position, improving the wrinkle removal effect.

[0052] In one embodiment, the guiding track of the guiding part is obtained according to the feeding tangent point position corresponding to each preset number of rotations of the winding roller.

[0053] In some embodiments, with the assistance of a computer, concentric circles are drawn with the axis of the winding roller 5 as the center. The diameter of each concentric circle increases successively with a preset value as the tolerance, and the feeding tangent point positions of each concentric circle and the winding roller 5 are respectively determined. After connecting the feeding tangent point positions, the tangent point path line can be obtained, and the trajectory of the tangent point path line is the guiding track of the guiding part 2.

[0054] In some embodiments, the preset value can be 1 mm to 3 mm.

[0055] Among them, the diameter of the smallest concentric circle is the diameter of the winding roller 5, and the diameter of the largest concentric circle is the diameter of the coil 6 after winding is completed.

[0056] In one embodiment, as Figure 1As shown, the guiding part 2 includes a first guiding part 201 and a second guiding part 202. The first guiding part 201 and the second guiding part 202 are arranged oppositely. Both ends of the wrinkle removing roller 3 are slidably connected to the first guiding part 201 and the second guiding part 202 respectively.

[0057] In this embodiment, as Figure 1 shown, the first guiding part 201 and the second guiding part 202 are correspondingly arranged, and both ends of the wrinkle removing roller 3 are slidably connected to the first guiding part 201 and the second guiding part 202 respectively, which can improve the stability of the wrinkle removing roller 3 during the sliding process, so that the wrinkle removing roller 3 and the winding roller 5 always remain parallel.

[0058] In one embodiment, as Figure 3 shown, it further includes a pressing mechanism 4. The pressing mechanism 4 includes a pressing part 401. The pressing part 401 is arranged on the mounting frame 1. The pressing part 401 is in transmission connection with the wrinkle removing roller 3 and is adapted to press the wrinkle removing roller 3 onto the winding roller 5.

[0059] In this embodiment, as Figure 3 shown, the pressing part 401 is arranged on the mounting frame 1. The pressing part 401 presses the wrinkle removing roller 3 onto the winding roller 5, and the contact position between the wrinkle removing roller 3 and the winding roller 5 is always the feeding tangent point position. The wrinkle removing roller 3 can flatten and remove wrinkles at the position where the material is wound onto the winding roller 5, with the best effect. After the wrinkle removing roller 3 flattens and removes wrinkles from the material, the material can be directly wound onto the winding roller 5 without going through the conveying process, and thus the situation of wrinkles occurring again during the subsequent conveying process will not occur.

[0060] In some embodiments, the pressing part 401 includes two elastic members. The two elastic members are located on both sides of the wrinkle removing roller 3. One ends of the two elastic members are connected to the mounting frame 1, and the other ends are connected to both ends of the wrinkle removing roller 3. Under the elastic force of the two elastic members, the wrinkle removing roller 3 is always pressed onto the winding roller 5.

[0061] In a further embodiment, the elastic member is a spring or an air spring.

[0062] In some embodiments, the pressing part 401 includes two driving cylinders. The two driving cylinders are located on both sides of the wrinkle removing roller 3. One ends of the two driving cylinders are hinged to the mounting frame 1, and their telescopic rods are respectively hinged to both ends of the wrinkle removing roller 3. Under the action of the two driving cylinders, the wrinkle removing roller 3 is always pressed onto the winding roller 5. A pressure sensor is arranged on the driving cylinder, which can detect the pressure on the wrinkle removing roller 3 in real time. The controller is electrically connected to the two driving cylinders, and the controller can set a preset pressure value, and then control the pressure of the driving cylinder on the wrinkle removing roller 3.

[0063] In some embodiments, the pressing portion 401 includes a traction mechanism and two traction ropes. The traction mechanism is installed on the mounting frame 1. One end of each of the two traction ropes is connected to each end of the wrinkle removal roller 3, and the other end is respectively connected to the traction mechanism in a transmission manner. The traction mechanism pulls the wrinkle removal roller 3 to move through the traction ropes, so that it is pressed against the winding roller 5.

[0064] In a further embodiment, the traction mechanism is a winch or a hoisting mechanism.

[0065] In one embodiment, as Figure 3 shown, the wrinkle removal roller 3 is adapted to slide and switch between a first position and a second position. In the first position state, the wrinkle removal roller 3 is in rolling contact with the feeding tangent point position of the winding roller 5. In the second position state, the wrinkle removal roller 3 is away from the winding roller 5, and the pressing portion 401 is adapted to drive the wrinkle removal roller 3 to keep it in the first position.

[0066] In this embodiment, as Figure 3 shown, during the winding operation, the pressing portion 401 drives the wrinkle removal roller 3 to be pressed against the winding roller 5, so that the material can be flattened and the wrinkles can be removed at the position where the material is wound onto the winding roller 5, and the effect is the best. After the wrinkle removal roller 3 flattens and removes the wrinkles of the material, the material can be directly wound onto the winding roller 5 without passing through the conveying process, and thus the situation of the material getting wrinkled again during the subsequent conveying process will not occur.

[0067] When the winding operation is completed, as Figure 3 shown, the pressing portion 401 stops applying pressure to the wrinkle removal roller 3, and the wrinkle removal roller 3 slides to the second position and is away from the winding roller 5 to unload the winding roller 5.

[0068] In one embodiment, as Figure 3 shown, the pressing portion 401 includes: a counterweight 4011, a first connecting rope 4013, and at least one first guide pulley 4012.

[0069] Specifically, the first guide pulley 4012 is rotatably connected to the mounting frame 1. One end of the first connecting rope 4013 is connected to the counterweight 4011, and the other end bypasses the first guide pulley 4012 and is connected to the wrinkle removal roller 3;

[0070] Wherein, in the height direction, the first position is higher than the second position, and the counterweight 4011 pulls the wrinkle removal roller 3 to keep it in the first position.

[0071] In this embodiment, as Figure 3 shown, the counterweight 4011 is connected to the wrinkle removal roller 3 through the first connecting rope 4013. The first position is higher than the second position. Under the action of the counterweight 4011, the wrinkle removal roller 3 can be pulled to move along the guiding track from the second position to the first position. The weight of the counterweight 4011 is greater than the weight of the wrinkle removal roller 3, and the wrinkle removal roller 3 can be pulled to always be pressed against the winding roller 5.

[0072] Through the action of the first connecting rope 4013 and the first guide pulley 4012, the acting force direction of the counterweight 4011 can be adjusted. By the gravity of the counterweight 4011 itself, the wrinkle removal roller 3 is pulled to move from the second position to the first position along the guiding track.

[0073] In some embodiments, both the first guide pulley 4012 and the first connecting rope 4013 are provided in two. The two first guide pulleys 4012 are rotatably connected to the mounting bracket 1. The two first guide pulleys 4012 are arranged oppositely. One ends of the two first connecting ropes 4013 are respectively connected to both ends of the wrinkle removal roller 3, and the other ends respectively bypass the two first guide pulleys 4012 and are connected to the counterweight 4011, improving the driving smoothness of the wrinkle removal roller 3 and ensuring that the acting forces on both sides of the wrinkle removal roller 3 are the same.

[0074] In some embodiments, as Figures 1 to 3 shown, the first guide pulley 4012 includes a plurality of them, forming two groups of guide pulley groups. Each group of guide pulley groups is in transmission connection with a first connecting rope 4013. The guide pulley group can adjust the positions of the counterweight 4011 and the mounting bracket 1, making the positions between the counterweight 4011 and the mounting bracket 1 more reasonable.

[0075] In one embodiment, the pressing mechanism 4 further includes a driving part 402. The driving part 402 is in transmission connection with the wrinkle removal roller 3 to enable the wrinkle removal roller 3 to slide from the first position to the second position.

[0076] In this embodiment, when the winding operation is completed, the driving part 402 can make the wrinkle removal roller 3 slide from the first position along the guiding track to the second position, and the wrinkle removal roller 3 is far away from the winding roller 5, facilitating the unloading of the winding roller 5.

[0077] In some embodiments, the driving mechanism includes a cylinder. The cylinder is installed on the mounting bracket 1, and the telescopic rod of the cylinder is connected to the wrinkle removal roller 3 for driving the wrinkle removal roller 3 to slide from the first position to the second position.

[0078] In a further embodiment, two cylinders are provided. The two cylinders are installed on the mounting bracket 1, and the cylinders are hinged to the mounting bracket 1. The telescopic rods of the two cylinders are respectively hinged to both ends of the wrinkle removal roller 3.

[0079] In one embodiment, as Figure 3 、 Figure 4 and Figure 6 shown, the driving part 402 includes: a support frame 4021, a winch 4022 and a second connecting rope 4023.

[0080] Specifically, the winch 4022 is installed on the support frame 4021. One end of the second connecting rope 4023 is in transmission connection with the winch 4022, and the other end is connected to the counterweight 4011.

[0081] In this embodiment, as Figure 3 , Figure 4 and Figure 6 show, the output end of the hoist 4022 is connected to one end of the second connecting rope 4023, and the other end of the second connecting rope 4023 is connected to the counterweight 4011. The hoist 4022 can drive the second connecting rope 4023 to pull the counterweight 4011 to move in the height direction. The counterweight 4011 moves and switches between the third position and the fourth position in the height direction. In the third position state, the counterweight 4011 drives the wrinkle removal roller 3 to remain in the first position. In the fourth position state, no tension is generated on the second connecting rope 4023 between the counterweight 4011 and the hoist 4022. Under the action of gravity, the wrinkle removal roller 3 slides from the first position to the second position, and the wrinkle removal roller 3 moves away from the winding roller 5, which is convenient for unloading the winding roller 5.

[0082] In some embodiments, as Figure 4 shows, a plurality of second guide wheels 4025 are provided on the support frame 4021. One end of the second connecting rope 4023 is connected to the output end of the hoist 4022, and the other end bypasses the plurality of second guide wheels 4025 and is connected to the counterweight 4011. Through the combination of the plurality of second guide wheels 4025, that is, the cooperation of movable pulleys and fixed pulleys, the tension required by the hoist 4022 is reduced.

[0083] In some embodiments, as Figure 4 shows, a weight 4024 is provided on the second connecting rope 4023. After the weight 4024 is provided, the hoist 4022 only needs to provide a very small tension to pull the counterweight 4011.

[0084] In a further embodiment, the hoist 4022 can also be replaced with an electric winch.

[0085] In one embodiment, as Figure 2 shows, the mounting bracket 1 includes two mounting plates 101, the two mounting plates 101 are arranged oppositely, and the first guiding portion 201 and the second guiding portion 202 are respectively arranged on the two mounting plates 101;

[0086] At least one of the first guiding portion 201 and the second guiding portion 202 is a guiding hole or a guiding groove or a guiding rail or a guiding rod.

[0087] In this embodiment, as Figure 2 shows, the two mounting plates 101 are arranged oppositely, and the two ends of the wrinkle removal roller 3 are respectively slidably connected to the first guiding portion 201 and the second guiding portion 202, which can improve the sliding stability of the wrinkle removal roller 3.

[0088] In some embodiments, as Figure 2As shown, the mounting bracket 1 further includes at least one connecting rod 102. The two ends of the connecting rod 102 are respectively fixedly connected to the two mounting plates 101. The fixed connection method can be welding, can be bolt and nut connection, or can be integrally formed. The two mounting plates 101 are arranged in parallel.

[0089] In a further embodiment, as Figure 2 shown, two connecting rods 102 are provided. The two connecting rods 102 are arranged in parallel, and a plurality of reinforcing rods 103 are fixedly connected between the two connecting rods 102.

The guiding track of the guiding hole is arc-shaped.

[0103] In a further embodiment, belt pulleys are connected to both ends of the connecting shaft 302, and the first connecting ropes 4013 are wound around the belt pulleys and connected to the belt pulleys.

[0104] In some embodiments, both the first guiding portion 201 and the second guiding portion 202 are guiding rods. Both ends of the connecting shaft 302 are respectively and slidably connected to the guiding rods, and both ends of the wrinkle removing roller 3 are connected to the counterweight 4011 through the first connecting ropes 4013. Under the action of the gravity of the counterweight 4011, the wrinkle removing roller 3 can be driven to maintain in the first position, so that it always rolls and abuts against the feeding tangent point position of the winding roller 5, and the material just contacting the winding roller 5 is flattened and the wrinkles are removed, improving the flatness of winding.

[0105] In a further embodiment, through holes are formed at both ends of the connecting shaft 302, and the guiding rods penetrate through the through holes and are slidably connected to the through holes.

[0106] In a second aspect, the present application further provides a winding device, including:

[0107] a winding and wrinkle removing mechanism;

[0108] a winding frame, on which a winding roller 5 is rotatably connected;

[0109] a winding driving mechanism, installed on the winding frame, and the winding driving mechanism is in transmission connection with the winding roller 5;

[0110] The wrinkle removing roller 3 can roll and abut against the feeding tangent point position of the winding roller 5.

[0111] In this embodiment, the winding driving mechanism is a winding motor, and the winding motor is in transmission connection with the winding roller 5 through a transmission assembly to drive the winding roller 5 to rotate for winding operation. The wrinkle removing roller 3 is slidably connected to the guiding portion 2. As the thickness of the material roll 6 increases, the change track of the feeding tangent point position is the same as the guiding track of the guiding portion 2, which can ensure that the wrinkle removing roller 3 always rolls and abuts against the feeding tangent point position during the process of the increase of the material thickness on the winding roller 5, improving the wrinkle removing effect.

[0112] In some embodiments, the transmission assembly may be a coupling, a gear set, or a pulley set and a belt.

[0113] Specifically, the winding device includes the above-mentioned winding and wrinkle-removing mechanism.

[0114] It should be noted that the winding device includes the winding and wrinkle-removing mechanism provided in the embodiments of the present application, so it simultaneously includes all the above-mentioned advantages of the winding and wrinkle-removing mechanism, and thus will not be elaborated herein.

[0115] Next, taking an embodiment as an example, in combination with Figures 1 to 6 the above-mentioned overall solution will be comprehensively elaborated.

[0116] Before the winding operation, the winding roller 5 is rotatably installed on the winding frame. The winding motor is drivingly connected to the winding roller 5 through a pulley set and a belt. The counterweight 4011 is connected to both ends of the connecting shaft 302 through two first connecting ropes 4013 and two sets of guide pulley sets. Under the action of the counterweight 4011, the connecting shaft 302 has a tendency to move from the second position to the first position by the first connecting rope 4013, so that the roller body 301 abuts against the material inlet tangent point position of the winding roller 5. The output end of the winch 4022 is connected to one end of the second connecting rope 4023, and the other end of the second connecting rope 4023 is connected to the counterweight 4011. The winch 4022 can drive the second connecting rope 4023 to pull the counterweight 4011 to move in the height direction. The counterweight 4011 moves and switches between the third position and the fourth position in the height direction. When the winch 4022 drives the counterweight 4011 to be in the third position state, the counterweight 4011 drives the wrinkle-removing roller 3 to remain in the first position. By adjusting the interval between the mounting frame 1 and the winding roller 5, the fixed distance between the wrinkle-removing roller 3 and the material roll 6 can be maintained.

[0117] During the winding operation, the winding motor rotates and drives the winding roller 5 to rotate through the pulley set and the belt. The winding roller 5 winds the material. The position where the winding roller 5 contacts the material is the material inlet tangent point position. The roller body 301 abuts against the material inlet tangent point position. The connecting shaft 302 is slidably connected to the guiding portion 2. As the thickness of the material roll 6 increases, the change trajectory of the material inlet tangent point position is the same as the guiding trajectory of the guiding portion 2, which can ensure that the roller body 301 always rolls and abuts against the material inlet tangent point position during the process of the increasing thickness of the material on the winding roller 5, improving the wrinkle-removing effect.

[0118] During the process of the increase in the thickness of the material coil 6, the counterweight 4011 always pulls the connecting shaft 302 through the first connecting rope 4013, so that the roller body 301 always rolls against the winding roller 5. Both the first guiding portion 201 and the second guiding portion 202 are guiding holes. Both ends of the connecting shaft 302 are connected with sliders. A sliding groove is arranged on the circumferential side of the slider. The groove wall of the sliding groove is slidably connected with the two end faces of the guiding hole, and the groove bottom of the sliding groove is slidably connected with the inner wall of the mounting hole, preventing the slider from detaching from the guiding hole. Under the action of the gravity of the counterweight 4011, the wrinkle removing roller 3 can be driven to stay at the first position, so that it always rolls against the feeding tangent point position of the winding roller 5, and the material just contacting the winding roller 5 is flattened and the wrinkles are removed, improving the flatness of winding.

[0119] Specifically, with the aid of computer, concentric circles are drawn with the axis of the winding roller 5 as the center. The diameter of each concentric circle increases successively with a preset value as the tolerance, and the feeding tangent point positions of each concentric circle and the winding roller 5 are respectively determined. After connecting the respective feeding tangent point positions, the tangent point path line can be obtained. The trajectory of the tangent point path line is the guiding trajectory of the guiding portion 2.

[0120] Among them, the diameter of the smallest concentric circle is the diameter of the winding roller 5, and the diameter of the largest concentric circle is the diameter of the material coil 6 after winding is completed. In the height direction, the first position is higher than the second position. The counterweight 4011 pulls the wrinkle removing roller 3 to keep it at the first position.

[0121] After the winding operation is completed, the output end of the winch 4022 is connected to one end of the second connecting rope 4023, and the other end of the second connecting rope 4023 is connected to the counterweight 4011. The winch 4022 can drive the second connecting rope 4023 to pull the counterweight 4011 to move in the height direction. The counterweight 4011 moves and switches between the third position and the fourth position along the height direction. When the winch 4022 drives the counterweight 4011 to be in the fourth position state, no tension is generated on the second connecting rope 4023 between the counterweight 4011 and the winch 4022. Under the action of gravity, the wrinkle removing roller 3 slides from the first position to the second position, and the wrinkle removing roller 3 moves away from the winding roller 5, facilitating the unloading of the winding roller 5.

[0122] Although the embodiments of the present application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations all fall within the scope defined by the appended claims of the present application.
