Description

Technical Field

[0001] This invention relates to the field of label backing paper processing equipment, and specifically to a roll label backing paper reinforcement device. Background Technology

[0002] Self-adhesive labels generally consist of three layers: face paper, adhesive, and backing paper. The backing paper, also known as release paper, serves to receive the release agent, protect the adhesive on the back of the face paper, and support the face paper so that it can be die-cut, waste removal, and labeled on the labeling machine.

[0003] In actual production, some manufacturers often reinforce the backing paper by laminating it with a layer of tape to improve its tensile strength and waterproof effect, preventing it from breaking during processing and affecting product production. Currently, the tape and backing paper are typically laminated manually, which is inefficient and makes it difficult to guarantee the bonding precision between the backing paper and tape, resulting in inconsistent product quality. Therefore, a backing paper reinforcement device that can automate the process and achieve high bonding precision is needed.

[0004] Therefore, a reinforcement device is needed that can achieve bonding of the backing paper and the tape while ensuring the accuracy of the bonding. Summary of the Invention

[0008] The present invention is further configured such that the guiding component includes a support frame fixedly mounted on the abutment plate, an adjusting plate slidably connected to the support frame, and a plurality of spaced guiding plates elastically connected to the side of the adjusting plate facing the abutment plate; it also includes a plurality of through slots disposed on the first feeding plate and the second feeding plate, wherein the plurality of through slots correspond one-to-one with the plurality of guiding plates.

[0009] The present invention is further configured such that the guide plate is provided with an arc-shaped through groove, the arc-shaped through groove corresponding to the first feeding plate or the second feeding plate; the upper surface of the arc-shaped through groove is provided with a limiting surface parallel to the first feeding plate or the second feeding plate, the limiting surface being able to abut against the side of the tape or backing paper close to the guide plate.

[0010] The present invention is further configured such that a plurality of pressing rods are elastically arranged above the middle of the first feeding plate and the second feeding plate, the pressing rods are hollow and the ends near the first feeding plate or the second feeding plate are rotatably connected to ball bearings.

[0011] The present invention is further configured such that the second correction mechanism includes a correction roller rotatably mounted on the frame, the correction roller being horizontally placed in the shape of an hourglass and including a positioning part, the two ends of the positioning part being provided with fixing parts with a diameter larger than the positioning part, and the fixing part and the positioning part being connected by an arc-shaped surface.

[0012] The invention is further configured such that a mounting rod is slidably connected to the adjusting plate, a guide plate is rotatably connected to one end of the mounting rod away from the adjusting plate, and an adjusting nut is threaded to the other end; a spring sleeved on the mounting rod is provided between the adjusting plate and the guide plate.

[0013] The present invention is further configured such that the unwinding mechanism includes a roll rack, on which a pair of material rollers are provided, the pair of material rollers being used to hold the bottom paper roll and the tape roll respectively; it also includes a transmission mechanism for driving the pair of material rollers to rotate in opposite directions, the transmission mechanism being connected to the driving mechanism.

[0016] In summary, the beneficial effects of this invention are as follows:

[0017] Compared with the prior art, this application enables the lamination process of the backing paper and the adhesive tape through the device configuration. The automated production can improve the production efficiency of the backing paper processing and increase the output. At the same time, the configuration of the first correction mechanism can improve the bonding accuracy between the backing paper and the adhesive tape, thereby improving the quality of the finished product.

[0018] In the first correction mechanism, the included angle formed between the feeding plate and the abutment plate allows the tape to align with one side of the backing paper. After passing through the pressure roller, the tape and the backing paper are aligned and bonded together. This ensures that the relative position between the tape and the backing paper will not shift when they are bonded together by the laminating mechanism, thus guaranteeing the bonding accuracy during lamination and reducing errors. This also ensures the processing quality when processing rolls with narrow widths.

[0019] The arc-shaped grooves and arc-shaped surfaces on the guide plate allow one side of the tape and backing paper to bend, thereby increasing the contact area between the guide plate and the roll material and preventing damage to one side of the roll material when the guide plate pushes the roll material towards the abutment plate.

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-6 As shown, this embodiment discloses a roll label backing paper reinforcement device, including an unwinding mechanism 3 mounted on a frame 1. The unwinding mechanism 3 includes a roll rack 31 fixedly mounted on the frame 1. Two material rollers 32 are rotatably connected to the roll rack 31. The pair of material rollers 32 are arranged vertically on the roll rack 31. The upper material roller 32 is used to place the backing paper roll, and the lower material roller 32 is used to place the tape roll. The two material rollers 32 are connected by a transmission mechanism, which is a pair of meshing gears. The gears are respectively located at one end of the two material rollers 32. Through gear transmission, the two material rollers 32 can rotate towards each other. One of the material rollers is connected to a drive mechanism.

[0029] The frame 1 is also equipped with a feeding mechanism 2. The two rolls of material on the material roller pass through the feeding mechanism 2 in sequence through the first correction mechanism 6, the compounding mechanism 4, and the second correction mechanism 231, and finally the two rolls are compounded and then wound onto the winding mechanism 5.

[0030] The winding mechanism 5 is a winding roller. When the winding roller rotates through the drive mechanism, it can wind up the finished product.

[0031] Among them, such as Figure 1 As shown, the winding mechanism 2 includes a bottom paper feeding group 21 and a tape feeding group 22, which are disposed between the first correction mechanism 6 and the unwinding mechanism 3 and correspond to the two material rollers 32 respectively. The bottom paper feeding group 21 includes a pair of feeding rollers 211 rotatably disposed on the frame 1 and arranged vertically. The ends of the pair of feeding rollers 211 are also synchronously rotated in opposite directions through gear transmission. One of the feeding rollers 211 is connected to the drive mechanism to achieve drive. The surface of the feeding roller 211 is provided with a dust removal adhesive layer 212. The dust removal adhesive layer 212 can clean the dust attached to the surface of the bottom paper, thereby facilitating the subsequent application of adhesive by the glue roller 213.

[0032] The tape feeding assembly 22 includes a pair of conveying rollers 221 rotatably mounted on the frame 1. The upper conveying roller 221 is an anilox roller, which can reduce the contact area with the tape surface, thereby avoiding damage to the tape surface.

[0033] It also includes several tension rollers, which can change the direction of the roll and maintain tension during the roll conveying process.

[0034] It also includes a finished product feeding group 23 disposed between the composite mechanism 4 and the winding mechanism 5. The finished product feeding group 23 includes clamping rollers rotatably disposed on the frame 1. The clamping rollers can rotate in opposite directions through a transmission mechanism, and one clamping roller is connected to a drive mechanism. It also includes a second correction mechanism 231 disposed at the front end of the winding mechanism 5. Figure 6 As shown, the second correction mechanism includes an hourglass-shaped correction roller 2311. The two ends of the correction roller 2311 are fixed parts with a diameter larger than that of the middle part, and the middle part is a positioning part 2312 with a smaller diameter. By setting the positioning part 2312, the finished roll material can be corrected twice before being conveyed to the winding mechanism 5. By using the inclined surface between the fixed part and the positioning part, the roll material can move towards the middle of the correction roller, thereby ensuring the quality of the roll material after winding.

[0035] Meanwhile, a first correction mechanism 6 is set between the laminating mechanism 4 and the unwinding mechanism. In existing equipment on the market, during the lamination process of the backing paper and the tape, the two sets of rolls are usually corrected and aligned before entering the laminating mechanism to reduce the error when the two sets of rolls are bonded. However, since the correction is generally dynamic and the rolls are not limited, there will still be some error, especially when laminating tape with a narrow width and backing paper, the error will be more obvious.

[0036] like Figure 2-5As shown, the first correction mechanism 6 includes an abutment plate 61 fixedly connected to the frame 1. A first feeding plate 62 and a second feeding plate 63 are fixedly disposed on the side of the abutment plate 61 away from the frame 1. The first feeding plate 62 is horizontally disposed, and the second feeding plate 63 is inclined towards the first feeding plate 62 along the winding conveying direction. A pair of limiting plates 64 are also disposed on the abutment plate 61, corresponding to the first feeding plate 62 and the second feeding plate 63 respectively. The pair of limiting plates 64 are respectively located above the first feeding plate 62 and the second feeding plate 63 and are perpendicular to the winding conveying direction. A limiting channel 65 is formed between the material plates, which is used to abut against one side of the backing paper or tape; it also includes a pair of guide components 66 elastically disposed on the side of the first feeding plate 62 and the second feeding plate 63 away from the abutment plate 61, which are used to move the backing paper and tape toward the limiting part; a pair of pressure rollers 67 are also provided at one end of the limiting channel 65 near the composite mechanism 4, which are used to bond the tape and backing paper to the side near the abutment plate 61; it also includes a separation plate 68 disposed on one side of the pressure rollers 67.

[0037] The guiding component 66 includes a support frame 661 fixedly mounted on the abutment plate 61, an adjusting plate 662 slidably connected to the support frame 661, and a plurality of spaced guide plates 663 elastically connected to the side of the adjusting plate 662 facing the abutment plate 61; it also includes a plurality of through slots 664 disposed on the first feeding plate 62 and the second feeding plate 63, and the plurality of through slots 664 correspond one-to-one with the plurality of guide plates 663.

[0038] In the above structure, the surfaces of the first feeding plate 62 and the second feeding plate 63 are provided with a water-based non-stick coating, which can prevent glue from adhering.

[0039] like Figure 3 As shown, when the two sets of rolls are conveyed to the feeding plate by the feeding mechanism, one side of the roll will abut against the abutment plate, and the other side will abut against the guide plate. Under the action of the guide plate, the offset rolls are gradually guided to move towards the abutment plate and enter the limiting channel 65. The limiting plate is inclined and arc-shaped, which can press down the rolls close to the abutment plate when one side of the rolls contacts the abutment plate, thus avoiding the rolls from lifting up due to abutment plate abutting and affecting the accuracy of bonding.

[0040] At the same time, such as Figure 3As shown, the guide plate 663 is provided with an arc-shaped through groove 6631, which corresponds to the first feeding plate 62 or the second feeding plate 63; the upper surface of the arc-shaped through groove 6631 is provided with a limiting surface 6632 parallel to the first feeding plate 62 or the second feeding plate 63, which can abut against the side of the tape or backing paper near the guide plate 663; the guide plate 6632 gradually approaches the abutting plate along the winding conveying direction by adjusting the nut until one side of the winding abuts against the abutting plate and the other side abuts against the limiting surface 6632.

[0041] By setting the arc-shaped through groove 6631, one side of the coil can be tilted upward when the guide plate contacts the coil, thereby increasing the contact area between the guide plate and the coil, so that the edge of the coil will not be damaged and tilted when the guide plate applies pressure to the coil.

[0042] Then as Figure 5 As shown, after being guided by the guide plate, one side of the two rolls of material abuts against the abutment plate, ensuring that one side of each roll is aligned. Then, as they pass the pressure roller 63, due to the presence of the separation plate 68, the backing paper and tape only adhere to each other on the side closest to the pressure roller 63. After the rolls detach from the guide plate, the side that abutted against the guide plate returns to its original position, and the remaining parts are then laminated under the pressure of the laminating mechanism. During the lamination process, since one side of each roll is already bonded and the rolls are under tension, they naturally unfold on the separation plate 68, ensuring that the other side of the two rolls remains aligned during the pressing process, guaranteeing complete adhesion and improving the lamination accuracy.

[0043] This ensures higher bonding precision and better results when processing base paper and tape with narrower widths, thus improving product molding quality.

[0044] A plurality of pressing rods 7 are elastically arranged above the middle of the first feeding plate 62 and the second feeding plate 63. The pressing rods 7 are hollow and are connected to ball bearings 71 by rolling at the ends near the first feeding plate 62 or the second feeding plate 63.

[0045] like Figure 4 As shown, the ball bearing 71 is rotatably disposed within the pressure rod 7, and the ball bearing is elastically disposed within the pressure rod 7. The pressure rod 7 can press down on the middle of the coil, thereby preventing the coil from warping and affecting alignment. Therefore, when the coil moves forward and also moves in the left and right directions, the pressure rod can be prevented from damaging the coil.

[0046] In the above structure, the drive mechanism is a servo motor, which is controlled by a control box.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present invention should be included within the protection scope of the present invention.
