Description

Technical Field

[0001] This utility model relates to the field of reflective ribbon bonding technology, and in particular to a multi-color reflective ribbon bonding device. Background Technology

[0002] In fields such as traffic facilities and safety protection, the demand for multi-color reflective tapes is increasing due to their eye-catching visual cues and nighttime reflective warning functions. The core of tape production lies in bonding the base adhesive tape, the middle tape, and the two side tapes of different colors.

[0003] However, existing multi-color reflective ribbon bonding equipment still has some problems in use:

[0004] Existing equipment often lacks a standardized guideline for tape roll positioning. Adhesive tape rolls and different colored label rolls are installed and positioned independently, relying on operators to visually inspect or use their experience to calibrate the roll positions. This method easily leads to misalignment of the tape adhesive due to inconsistent guidelines. For example, white label may deviate from the center of the adhesive tape, or black label may not be symmetrically distributed on both sides of the white label, resulting in an irregular "black-white-black" label structure. Such defects not only cause the label to fail to meet standards in appearance but also damage the uniformity of the reflective coating, causing uneven reflectivity at night, weakening the warning effect, and increasing safety hazards. Utility Model Content

[0005] The purpose of this invention is to provide a multi-color reflective ribbon bonding device, which solves the above-mentioned problems by using this device.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a multi-color reflective tape bonding device, including a base, a pressing roller assembly and a winding roller assembly. The pressing roller assembly is provided at the middle position of the top of the base. The winding roller assembly is provided at one end of the pressing roller assembly. The other end of the pressing roller assembly is provided with a side frame. A first feeding roller is provided at the bottom of one side of the side frame. A second feeding roller is provided at the middle position of one side of the side frame. A third feeding roller is provided at the top of one side of the side frame. A first tape roll is installed on one side of the outer side of the third feeding roller. A second tape roll is installed on the other side of the outer side of the third feeding roller. A limit baffle is provided on one side of the first tape roll. A limit retaining ring is provided on one side of the second tape roll.

[0007] Preferably, the upper and lower ends and the middle position of the limiting baffle are provided with through grooves, and the limiting baffle is sleeved on the feeding roller one, feeding roller two and feeding roller three through the through grooves and can slide outside them.

[0008] Preferably, a movable support rod is transversely arranged inside the limiting baffle. The movable support rod is located diagonally below the feeding roller three. One end of the movable support rod is fixed with a connecting seat. The limiting retaining ring is rotatably set on the connecting seat. Two support sleeves are sleeved on the outside of the movable support rod. The support sleeves are respectively fixed on the two side walls of the limiting baffle. A locking bolt is threaded on one side of the support sleeve. The locking bolt extends into the support sleeve and contacts the side wall of the movable support rod.

[0009] Preferably, the inner diameter of the limiting retaining ring matches the outer diameter of the feeding roller three, and the limiting retaining ring can be locked onto the outside of the feeding roller three.

[0010] Preferably, the bottom of the limiting baffle is provided with a sliding groove, which is opened at the top of the base. A slider is slidably arranged inside the sliding groove and the slider is fixed to the bottom of the limiting baffle. Support blocks are provided on both sides of the top of the sliding groove and the support blocks are fixed to the side wall of the limiting baffle. A threaded post is threadedly connected inside the support block, and a stop block is fixed at the bottom of the threaded post. The stop block contacts the top of the base.

[0011] Preferably, there are two support blocks, which are symmetrical on both sides of the center line at the top of the chute.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model provides a multi-color reflective tape bonding device. A limiting baffle serves as a common reference for the adhesive tape roll, white label roll, and first black label roll, ensuring that the three types of tapes are always aligned with the same reference during the bonding process, avoiding misalignment caused by inconsistent references. Simultaneously, a limiting ring adjusts the position of the second black label roll, controlling the spacing between the two sets of black label rolls. This ensures that in the final "black-white-black" structured label, the white label is centered and the black label is symmetrically distributed on both sides, with controllable positional errors. This meets the structural precision requirements of reflective tapes and effectively avoids problems such as uneven reflectivity and appearance defects caused by label misalignment.

[0014] The limiting ring can be adjusted to any position along the three axes of the feeding roller by moving the movable support rod. Combined with the fixing function of the locking bolt, the spacing between two sets of black label tape rolls can be flexibly adjusted according to the width of the black label tape roll. This meets the production needs of multi-color reflective tapes and allows for adjustment of the label tape width ratio according to actual order requirements. Simultaneously, the limiting baffle can move flexibly on the base via a sliding groove, accommodating adhesive tape rolls and tape rolls of different diameters, avoiding limiting failure due to changes in tape roll diameter. This adjustable design eliminates the need to replace dedicated limiting components for different label tape specifications, reducing equipment modification and maintenance costs and improving the equipment's applicability in the production of various label tapes.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0023] Combination Figures 1 to 5 As shown, the present invention discloses a multi-color reflective tape bonding device, comprising a base 1, a pressing roller assembly 2, and a winding roller assembly 3. The pressing roller assembly 2 is located at the middle position of the top of the base 1, the winding roller assembly 3 is located at one end of the pressing roller assembly 2, and a side frame 4 is located at the other end of the pressing roller assembly 2. A first feeding roller 5 is located at the bottom of one side of the side frame 4, a second feeding roller 6 is located at the middle position of one side of the side frame 4, and a third feeding roller 7 is located at the top of one side of the side frame 4. A first label roll 71 is installed on one side of the outer side of the third feeding roller 7, and a second label roll 72 is installed on the other side of the outer side of the third feeding roller 7. A limit baffle 8 is provided on one side of the first label roll 71, and a limit retaining ring 81 is provided on one side of the second label roll 72.

[0024] The upper and lower ends and the middle position of the limiting baffle 8 are provided with through grooves. The limiting baffle 8 is sleeved on the feeding roller 1 5, feeding roller 2 6 and feeding roller 3 7 through the through grooves and can slide outside of them.

[0025] A movable support rod 82 is horizontally installed inside the limiting baffle 8. The movable support rod 82 is located diagonally below the feeding roller 7. One end of the movable support rod 82 is fixed with a connecting seat 83. The limiting retaining ring 81 is rotatably mounted on the connecting seat 83. Two support sleeves 84 are sleeved on the outside of the movable support rod 82. The support sleeves 84 are fixed to the two side walls of the limiting baffle 8. A locking bolt 85 is threadedly connected to one side of the support sleeve 84. The locking bolt 85 extends into the support sleeve 84 and contacts the side wall of the movable support rod 82.

[0026] The inner diameter of the limiting ring 81 matches the outer diameter of the feeding roller 7, and the limiting ring 81 can be locked onto the outside of the feeding roller 7.

[0027] The bottom of the limiting baffle 8 is provided with a sliding groove 9, which is opened at the top of the base 1. A slider 91 is slidably arranged inside the sliding groove 9, and the slider 91 is fixed to the bottom of the limiting baffle 8. Support blocks 92 are provided on both sides of the top of the sliding groove 9, and the support blocks 92 are fixed to the side wall of the limiting baffle 8. A threaded post 93 is threadedly connected inside the support block 92, and a stop block 94 is fixed at the bottom of the threaded post 93. The stop block 94 contacts the top of the base 1.

[0028] There are two support blocks 92, which are symmetrical on both sides of the top center line of the slide groove 9.

[0029] Working principle:

[0030] The multi-color reflective tape consists of three types of tape: a base adhesive tape, a middle layer of white tape, and two side layers of black tape, including a first tape roll 71 and a second tape roll 72.

[0031] Using specialized adhesive equipment, the white label tape is first bonded to the adhesive tape, and then two sets of black label tapes are bonded to both sides of the white label tape respectively, ultimately forming a multi-color reflective label tape with a "black, white and black" structure. The key is to ensure the alignment accuracy of each layer of label tape by limiting the tape roll.

[0032] The limiting baffle 8 serves as a common limiting reference for both the adhesive tape roll and the white label tape roll. Its position must be fixed first, as follows:

[0033] Push the limit baffle 8 so that the slider 91 at its bottom slides along the groove 9 on the base 1 until it moves to the preset reference position;

[0034] Rotate the threaded post 93 that is matched with the limit baffle 8, and drive the bottom block 94 of the threaded post 93 to move downward until the block 94 is tightly pressed against the top of the base 1. At this time, the position of the limit baffle 8 is completely fixed and cannot slide along the slide groove 9.

[0035] Phase 1: Installation and positioning of adhesive tape rolls and white label tape rolls:

[0036] Using the fixed limiting baffle 8 as a reference, install the two types of tape rolls sequentially to ensure their docking accuracy:

[0037] Install the adhesive tape roll on the feed roller 5: Place the adhesive tape roll on the feed roller 5, adjust the position of the roll so that one side wall of the adhesive tape roll is completely pressed against the side wall of the limiting baffle 8. The limiting baffle 8 is used to block the radial movement of the adhesive tape roll and prevent the roll from deviating.

[0038] White label roll installation on feed roller 26: Similarly, the white label roll is placed on feed roller 26 so that one side wall of the white label roll is tightly pressed against the side wall of the limiting baffle 8. By using the limiting reference consistent with the adhesive tape roll, the axial alignment of the white label roll and the adhesive tape is ensured when they are bonded.

[0039] Phase Two: Installation and Limiting of Two Sets of Black Label Rolls:

[0040] For the feeding roller 37, two sets of black label tape rolls need to be installed simultaneously. A combination of "baseline limit + adjustable limit" is required to ensure that the two sets of black label tape are positioned on either side of the white label tape. The steps are as follows:

[0041] Installation of the first label roll 71: Place the first label roll 71 onto the feeding roller 3 7, so that one side wall of the first label roll 71 abuts against the side wall of the limiting baffle 8. Using the previously set reference, complete the limiting and fixing installation of the first set of black label rolls.

[0042] Position adjustment and fixing of limit ring 81:

[0043] Push the movable support rod 82 to drive the limit ring 81 to move along the three axes of the feeding roller 7 until it moves to the preset position that matches the first label roll 71, ensuring that the second label roll 72 can be located on the other side of the white label after installation.

[0044] Rotate the locking bolt 85 that is matched with the movable support rod 82 so that the end of the locking bolt 85 is tightly pressed against the side wall of the movable support rod 82, and the position of the movable support rod 82 is locked by friction, thereby ensuring that the position of the limit ring 81 remains fixed.

[0045] Installation of the second label roll 72: The second label roll 72 is placed on the feeding roller 3 7, so that one side wall of the second label roll 72 is pressed against the side wall of the limiting ring 81. The limiting ring 81 is used to block the second set of black label rolls, and finally the structural requirement that the two sets of black label rolls are located on both sides of the white label roll is achieved.

[0046] The helical transmission structure of "threaded column 93-stop block 94" converts the rotational motion into linear motion, so that the stop block 94 and the base 1 are rigidly pressed together. The static friction force is used to counteract the sliding tendency of the limit baffle 8, ensuring the stability of the reference position and avoiding the reference deviation caused by the lateral force generated by the rotation of the belt roll.

[0047] By tightening the locking bolt 85 against the side wall of the movable support rod 82, a point-to-surface contact pressure fixation is formed. This method allows for quick adjustment and locking of the position, and the fixing strength can be controlled by the bolt tightening force, adapting to the limiting requirements of different tape rolls.
