Description

Technical Field

[0001] This invention belongs to the field of self-adhesive technology, and specifically relates to a self-adhesive label preparation apparatus and a self-adhesive label. Background Technology

[0002] Self-adhesive labels, also known as pressure-sensitive labels, are composite materials consisting of a film as the face stock, an adhesive coating on the back, and a silicone-coated release liner. During film processing, the film undergoes biaxial stretching, followed by stamping, printing, and other processes. The film is typically wound into a cylindrical shape on a rotating winding drum.

[0003] A search revealed that Chinese Patent Publication No. CN210594450U, authorized on May 22, 2020, discloses a polymer self-adhesive label preparation device, relating to the field of self-adhesive labels. The device includes a base, a support column, a motor, a main shaft, limiting discs, limiting rods, a drive rod, and a lifting unit. The main shaft is rotatably mounted on the support column. The motor is poweredly connected to one end of the main shaft. Two limiting discs are sleeved on the side surface of the main shaft. A drive groove is provided inside the main shaft. The two limiting discs are radially arranged facing each other and evenly spaced axially. Several slid grooves are provided, with a limiting rod slidably connected to the slid groove and the limiting rod slidably connected to the drive groove. One end of the limiting rod extends to the outside of the other end of the main shaft. The limiting plate is provided with a lifting part corresponding to the limiting rod. If the winding radius of the self-adhesive label exceeds the radius of the limiting plate during the winding process, an external force is applied to the drive rod, causing it to drive the limiting rod to extend outward along the slid groove through the lifting part. This allows the device to adapt to the radius change during the winding of the self-adhesive label, avoiding the problem of easy deviation and uneven winding caused by insufficient radius of the limiting plate.

[0004] However, the equipment still has the following defects: although it can avoid the problem of misalignment and uneven winding caused by insufficient limit plate radius, it cannot properly customize the release paper roll on the long paper tube before and after winding, which means that the self-adhesive labels after winding need to be used in conjunction with other equipment, affecting the production efficiency of forming.

[0008] Furthermore, a drive rod is slidably connected to the inner wall of the linkage wheel, and one end of the drive rod is provided with a conical head. Both the conical head and the outer wall of the drive rod are provided with a number of positioning radial columns. The inner wall of the linkage wheel is also provided with a sliding groove for guiding the number of positioning radial columns. The other end of the drive rod is connected to the output end of the first cylinder, and a bearing is rotatably connected between the output end of the first cylinder and the connection point of the drive rod.

[0009] Furthermore, the marking assembly includes a linkage roller; both ends of the linkage roller are drivenly connected to the output end of a servo motor; the outer wall of the linkage roller has an adjustment cavity, and the inner wall of the adjustment cavity is slidably fitted with an assembly block; the top of the assembly block is fixedly connected with several sets of punching pins; both ends of the inner wall of the adjustment cavity are fixedly connected with a stop block; both ends of the assembly block are threadedly connected with a lead screw; one end of the lead screw is rotatably connected to the bottom end of the inner wall of the adjustment cavity; the other end of the lead screw is drivenly connected to a stepper motor, and the side of the stepper motor away from the output end is embedded in the bottom of the stop block.

[0010] Furthermore, the paper tube feeding assembly includes a receiving tube; the top of the receiving tube has a feeding port, and one side of the outer wall of the receiving tube has a discharging port; the inner wall of the receiving tube is rotatably connected to a feeding roller; the outer wall of the feeding roller has several sets of grooves, and the inner wall of each of the several sets of grooves is provided with a long paper tube; the bottom of the receiving tube is fixedly connected to a lower curved arm, and the other end of the lower curved arm is rotatably connected to a linkage shaft.

[0011] Furthermore, the two ends of the linkage shaft are rotatably connected to guide rails, and the end of the guide rail and the side away from the storage cylinder are provided with a limiting seat for positioning the long paper tube. An adsorption pump is also embedded in one side of the outer wall of the limiting seat, and the input end of the adsorption pump extends to the other side wall of the limiting seat. The bottom of the guide rail is movably connected to a second cylinder, and the side of the second cylinder away from the output end is fixedly connected to the top of the support plate.

[0012] A self-adhesive label includes a self-adhesive label body, which comprises, from top to bottom, a face material layer, a pressure-sensitive adhesive layer, a release agent coating, and a backing paper layer. The thickness of the release agent coating is 3-10 μm, and the thickness of the pressure-sensitive adhesive layer is 15-40 μm.

[0013] Furthermore, the face material layer is any one of coated paper, thermal paper, PET film, BOPP film or PE film, with a thickness of 25-150μm.

[0014] Furthermore, the release agent coating is an organosilicon release agent coating, and the pressure-sensitive adhesive layer is any one of water-based acrylic pressure-sensitive adhesive layer, solvent-based acrylic pressure-sensitive adhesive layer, or UV-cured pressure-sensitive adhesive layer.

[0015] The beneficial effects of this invention are: 1. The paper tube feeding assembly is used to sequentially feed the built-in long paper tubes between the two sets of linkage components. The position of the long paper tubes after feeding is adjusted by the adjustment function of the drive component, and the connection angle between the long paper tubes and the ends of the release paper rolls is switched. After the ends of the release paper rolls are attached to the long paper tubes, this reduces the risk of the release paper rolls being wound onto the long paper tubes at an angle during the rotation of the two sets of linkage components driven by the drive wheel via the belt. This maintains the recognition efficiency during the automatic attachment process of the release paper rolls and long paper tubes and is beneficial to the stability of the long paper tubes during winding.

[0016] 2. The output end of the first cylinder drives the drive rod to move horizontally, so that the conical head extends to the inner wall of the long paper tube port. The positioning pin increases the anti-slip stability during rotation after connecting with the long paper tube. Then, the rotation of the drive wheel drives the belt to rotate, so that the linkage wheel rotates at the same time, driving the drive rod and the long paper tube, for synchronous winding of the release paper roll on the long paper tube.

[0017] 3. The output end of the electric slide table drives the servo motor and the linkage roller to move, so that the linkage roller gradually approaches the conical head. This is used to squeeze the release paper roll on the outer wall of the long paper tube during the winding process, eliminate the air brought in during winding, and reduce the formation of air bubbles and wrinkles between label layers. At the same time as the lead screw rotates, it can also drive the assembly block to move radially along the lead screw. In this process, it can also drive several sets of punching needles to separate from the adjustment cavity. The sharp ends of the punching needles are used to punch holes in the outer wall of the release paper roll, forming a serrated edge that makes it easy to tear the release paper roll.

[0018] 4. The output end of the second cylinder cancels the bottom contact of the two sets of guide rails, causing the two sets of guide rails to rotate around the linkage shaft. This allows the two ends of the long paper tube to be suspended and positioned by the conical head, and the two sets of cutting wheels to be driven by the linkage bending rod as it falls along the hollow slide cavity. The cutting wheels in the rotation process cut the long paper tube after it is rolled up at equal intervals, and finally the release paper roll and self-adhesive label on the long paper tube are prepared.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1 This invention provides an apparatus for preparing self-adhesive labels and a self-adhesive label, including a support plate 1, two sets of linkage components 3, and two sets of drive wheels 4; for example, Figure 1 , Figure 2 and Figure 3 As shown.

[0025] A drive assembly 2 is fixedly connected to the top of the support plate 1. Two sets of linkage assemblies 3 are rotatably connected to the bottom of the inner wall of the drive assembly 2. Two sets of drive wheels 4 are driven to the top of the inner wall of the drive assembly 2. A belt 5 that is driven to the linkage assembly 3 is sleeved on each of the two sets of drive wheels 4. A marking assembly 6 is also driven between the two sets of drive assemblies 2. A paper tube feeding assembly 8 is also installed on the top of the support plate 1. Two sets of limiting arms 9 are also provided on the top of the support plate 1. A release paper roll 7 is rotatably connected between the two sets of limiting arms 9. Several sets of self-adhesive label bodies 10 are adhered to the outer wall of the release paper roll 7.

[0026] Specifically, the paper tube feeding component 8 is used to sequentially feed the built-in long paper tubes between the two sets of linkage components 3, and to adjust the position of the fed long paper tubes by using the adjustment function of the drive component 2, switching the connection angle between the long paper tubes and the ends of the release paper rolls 7, so that the ends of the release paper rolls 7 are in contact with the long paper tubes. This is to reduce the risk of the release paper rolls 7 being rolled onto the long paper tubes in an inclined state during the rotation of the two sets of linkage components 3 driven by the drive wheel 4 through the belt 5, and to maintain the recognition efficiency during the automatic bonding process between the release paper rolls 7 and the long paper tubes, which is beneficial to the stability of the long paper tubes during winding.

[0027] The drive component 2 includes a support frame 21; for example, such as Figure 4 and Figure 5 As shown.

[0028] Hollow sliding cavities 22 are provided on both sides of the outer wall of the support frame 21, and the inner walls of the two sets of hollow sliding cavities 22 are slidably connected with linkage bent rods 23. The ends of the two sets of linkage bent rods 23 are connected to adjusting rods 24 through the output end of the motor, and two sets of cutting wheels 25 are fixedly connected to the adjusting rods 24. First cylinders 26 are also embedded on both sides of the outer wall of the support frame 21, and the output end of the first cylinders 26 is connected to the linkage assembly 3.

[0029] The linkage component 3 includes a linkage wheel 31; for example, such as Figure 6 As shown.

[0030] One side of the outer wall of the linkage wheel 31 is rotatably connected to a limiting ring 32, and the other side of the outer wall of the linkage wheel 31 is rotatably connected to an extension ring 33. An electric slide table 34 is fixedly connected to the outer wall of the extension ring 33, and a servo motor 35 is driven to the output end of the electric slide table 34. The output end of the servo motor 35 is driven to the marking component 6. A drive rod 36 is slidably connected to the inner wall of the linkage wheel 31, and a tapered head 37 is provided at one end of the drive rod 36. Both the tapered head 37 and the outer wall of the drive rod 36 are provided with several sets of positioning radial columns 38. The inner wall of the linkage wheel 31 is also provided with a sliding groove for guiding several sets of positioning radial columns 38. The other end of the drive rod 36 is driven to the output end of the first cylinder 26, and a bearing is rotatably connected between the output end of the first cylinder 26 and the connection point of the drive rod 36.

[0031] The marking component 6 includes a linkage roller 61; for example, such as Figure 7 As shown.

[0032] Both ends of the linkage roller 61 are driven to the output end of the servo motor 35. The outer wall of the linkage roller 61 is provided with an adjustment cavity 62, and the inner wall of the adjustment cavity 62 is slidably fitted with an assembly block 63. Several sets of punching pins 64 are fixedly connected to the top of the assembly block 63. Both ends of the inner wall of the adjustment cavity 62 are fixedly connected with a stop block 65. Both ends of the assembly block 63 are threaded with a lead screw 66. One end of the lead screw 66 is rotatably connected to the bottom end of the inner wall of the adjustment cavity 62, and the other end of the lead screw 66 is driven to a stepper motor. The side of the stepper motor away from the output end is embedded in the bottom of the stop block 65.

[0033] The paper tube feeding assembly 8 includes a receiving tube 81; for example, such as Figure 8 As shown.

[0034] The top of the storage cylinder 81 has a feed inlet 82, and one side of the outer wall of the storage cylinder 81 has a discharge outlet 83. A feeding roller 84 is rotatably connected to the inner wall of the storage cylinder 81. The outer wall of the feeding roller 84 has several sets of grooves, and the inner wall of each set of grooves is provided with a long paper tube 85. A lower curved arm 86 is fixedly connected to the bottom of the storage cylinder 81, and the other end of the lower curved arm 86 is rotatably connected to a linkage shaft 87. Both ends of the linkage shaft 87 are also rotatably connected... A guide rail 88 is provided, and a limiting seat 89 for positioning a long paper tube 85 is provided at the end of the guide rail 88 and on the side away from the storage cylinder 81. An adsorption pump 810 is also embedded in one side of the outer wall of the limiting seat 89, and the input end of the adsorption pump 810 extends to the other side wall of the limiting seat 89. A second cylinder 811 is movably connected to the bottom of the guide rail 88, and the side of the second cylinder 811 away from the output end is fixedly connected to the top of the support plate 1.

[0035] Furthermore, a motor for driving the material feeding roller 84 to rotate is also embedded on one side of the outer wall of the storage cylinder 81.

[0036] Specifically, the rotation of the feeding roller 84 is used to switch the position of several sets of grooves. When the groove that does not contain long paper tubes 85 moves to the feed inlet 82, it is convenient to add long paper tubes 85 into the groove through the feed inlet 82 for automatic replenishment of long paper tubes 85. Then, by rotating the feeding roller 84, the long paper tubes 85 in the groove are moved to a position close to the discharge outlet 83 and guided by the guide rails 88 on both sides. The lifting and lowering of the output end of the second cylinder 811 abuts against the bottom of the two sets of guide rails 88, causing the two sets of guide rails 88 to rotate around the linkage shaft 87 as the center, which is used to adjust the position of the limit seat 89. During the adjustment of the limit seat 89, the long paper tube 85 is driven synchronously. The gap between the long paper tube 85 and the adsorption pump 810 is used to facilitate the contact of the end of the release paper roll 7. The continuous operation of the adsorption pump 810 stabilizes both sides of the end of the release paper roll 7 within the limit seat 89. After the technician stretches the release paper roll 7 so that both sides of its end extend into the limit seat 89, it is used to maintain the accuracy of the release paper roll 7 and the long paper tube 85 when they are attached, and to avoid the release paper roll 7 and the long paper tube 85 from shifting during the docking process. The output end of the first cylinder 26 drives the drive rod 36 to move horizontally, so that the conical head 37 extends to the inner wall of the port of the long paper tube 85. The positioning pin 38 is used to increase the anti-slip stability during rotation after connecting with the long paper tube 85. Then, the rotation of the drive wheel 4 drives the rotation of the belt 5, so that the linkage wheel 31 rotates while driving the drive rod 36 and the long paper tube 85, which is used to perform synchronous winding operation on the release paper roll 7 on the long paper tube 85. The output end of the electric slide table 34 drives the servo motor 35 and the linkage roller 61 to move, so that the linkage roller 61 gradually approaches the conical head 37, which is used to squeeze the release paper roll 7 on the outer wall of the long paper tube 85 during the winding process, eliminate the air brought in during winding, reduce the formation of air bubbles and wrinkles between label layers, and can also drive the assembly block 63 to move radially along the lead screw 66 while the lead screw 66 rotates. In this process, several sets of perforating needles 64 are driven to separate from the adjustment cavity 62, and the sharp ends of several sets of perforating needles 64 are used to perforate the outer wall of the release paper roll 7, forming a serrated edge that is easy to tear the release paper roll 7. After the output end of the second cylinder 811 cancels its contact with the bottom of the two sets of guide rails 88, the two sets of guide rails 88 rotate around the linkage shaft 87, so that the two ends of the long paper tube 85 are in a state of being horizontally clamped and suspended by the conical head 37. Then, the linkage bent rod 23 drives the two sets of cutting wheels 25 as it falls along the hollow slide cavity 22, so that the cutting wheels 25 in the rotation process cut the long paper tube 85 after it is rolled up at equal intervals. Finally, the release paper roll 7 and the self-adhesive label on the long paper tube 85 are prepared.

[0037] Example 2 This invention provides a self-adhesive label, including a self-adhesive label body 10, which comprises, from top to bottom, a face material layer, a pressure-sensitive adhesive layer, a release agent coating, and a backing paper layer.

[0038] Furthermore, the thickness of the release agent coating is 3-10 μm.

[0039] Furthermore, the thickness of the pressure-sensitive adhesive layer is 15-40 μm.

[0040] Furthermore, the face material layer is any one of coated paper, thermal paper, PET film, BOPP film or PE film, with a thickness of 25-150μm.

[0041] Furthermore, the release agent coating is an organosilicon release agent coating, and the pressure-sensitive adhesive layer is any one of water-based acrylic pressure-sensitive adhesive layer, solvent-based acrylic pressure-sensitive adhesive layer, or UV-cured pressure-sensitive adhesive layer.

[0042] The working principle of the self-adhesive label preparation apparatus proposed in this embodiment of the invention is as follows: The rotation of the feeding roller 84 switches the positions of several sets of grooves. When a groove without a long paper tube 85 moves to the feed inlet 82, it facilitates the addition of the long paper tube 85 into the groove through the feed inlet 82 for automatic replenishment of the long paper tube 85. Then, the rotation of the feeding roller 84 moves the long paper tube 85 in the groove to a position close to the discharge outlet 83, and it is guided by the two guide rails 88 on both sides. The lifting and lowering of the output end of the second cylinder 811 abuts the bottom of the two sets of guide rails 88, causing the two sets of guide rails 88 to rotate around the linkage shaft 87, which is used to adjust the position of the limit seat 89. During the adjustment of the limit seat 89, the long paper tube 85 is driven synchronously. The gap between the release paper roll 5 and the adsorption pump 810 facilitates contact between the ends of the release paper roll 7 and the end of the release paper roll 7 within the limiting seat 89 by the continuous operation of the adsorption pump 810. After the technician stretches the release paper roll 7 so that the ends extend into the limiting seat 89, the precision of the release paper roll 7 and the ends of the long paper tube 85 is maintained at all times, preventing misalignment between the release paper roll 7 and the long paper tube 85 during the docking process. The output end of the first cylinder 26 drives the drive rod 36 to move horizontally, extending the conical head 37 to the inner wall of the port of the long paper tube 85. The positioning pin 38 increases the anti-slip stability during rotation after connection with the long paper tube 85. The rotation of the drive wheel 4 drives the belt 5 to rotate, which in turn rotates the linkage wheel 31 and drives the drive rod 36 and the long paper tube 85 to perform synchronous winding of the release paper roll 7 on the long paper tube 85. The output end of the electric slide table 34 drives the servo motor 35 and the linkage roller 61 to move, so that the linkage roller 61 gradually approaches the conical head 37 to squeeze the release paper roll 7 on the outer wall of the long paper tube 85 during winding, eliminating the air introduced during winding, reducing the formation of air bubbles and wrinkles between label layers. At the same time as the lead screw 66 rotates, it can also drive the assembly block 63 to move radially along the lead screw 66, and in this process, drive several sets of punching needles 64 from the adjustment cavity 62. The release paper roll 7 is separated and perforated on its outer wall using the sharp ends of several sets of perforating needles 64, forming a serrated edge that facilitates tearing of the release paper roll 7. After the output end of the second cylinder 811 cancels the contact between the bottom of the two sets of guide rails 88, the two sets of guide rails 88 rotate around the linkage shaft 87, so that the two ends of the long paper tube 85 are horizontally clamped and suspended by the conical head 37. Then, the linkage bent rod 23 drives the two sets of cutting wheels 25 as it falls along the hollow slide cavity 22, so that the cutting wheels 25 cut the long paper tube 85 after it is rolled up at equal intervals. Finally, the release paper roll 7 and the self-adhesive label on the long paper tube 85 are prepared.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
