Description

Technical Field

[0001] This utility model relates to the field of document label technology, specifically to a quick-attachment auxiliary card for document labels. Background Technology

[0002] In the field of records management, labeling is a basic and frequent operation. Its purpose is to record key information of the records through labels to facilitate the retrieval, classification and management of the records. The traditional method of labeling records mainly relies on manual operation, that is, staff members take off individual labels from the label tape one by one and then stick them in the preset position on the record.

[0003] However, this traditional method has shortcomings when labeling large batches of files. First, the process is cumbersome, requiring staff to repeatedly perform the repetitive actions of "taking the label, aligning it, and pressing it to stick," which is labor-intensive, easily leads to fatigue, and results in low work efficiency. Second, manual pasting makes it difficult to ensure the consistency of label positions, easily causing problems such as labels being crooked or offset, affecting the neatness and standardization of the files. Third, labels are easily contaminated by direct hand contact during handling and pasting, or uneven pressure can lead to weak adhesion, increasing the risk of labels falling off and thus affecting the accuracy of file management. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary card for quick pasting of file labels. It has the advantages of efficient batch operation and avoiding label contamination, and solves the problems of cumbersome manual label removal, low efficiency of large-scale operation and easy contamination of the label pasting surface in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This document label quick-application auxiliary card includes a support component, which includes a support base. A labeling component is mounted on the outer wall of the support base. The labeling component includes an adhesive frame fixed to the left edge of the support base. Rotary rollers are rotatably mounted on the inner walls of both ends of the adhesive frame. The outer walls of the rotary rollers are flush with the lower edge of the adhesive frame. The shaft of the rotary roller passes through the inner wall of the adhesive frame and is fixedly connected to a pulley. A second pulley is rotatably mounted on the front end of the support base. Pulley 1 and pulley 2 are connected by a belt. A gear 1 is fixedly connected to the outer wall of the shaft of pulley 2. A third rotating frame is fixedly connected to the lower end of the support base. The inner walls at both ends of the rotating frame 3 are rotatably equipped with clamping rollers 1 and 2, which are distributed vertically. The rotating shaft of clamping roller 1 passes through the front end of the rotating frame 3 and is fixedly connected to gear 2. The rotating shaft of clamping roller 2 passes through the front end of the rotating frame 3 and is fixedly connected to gear 3. Gear 1 meshes with gear 2, and gear 2 meshes with gear 3. The bearing assembly is also equipped with a conveying assembly, which includes a bearing belt set on the inner wall of the lower end of the bearing seat. The bearing belt passes between the rotating roller and the bonding frame. The end of the bearing belt is located between clamping roller 1 and clamping roller 2. Several paper labels are pasted on the outer wall of the bearing belt at equal intervals.

[0007] Preferably, a symmetrically positioned limiting frame is fixed to the upper edge of the bearing seat, and several equidistant limiting wheels are rotatably installed on the inner wall of the limiting frame, with the outer wall of the limiting wheels fitting against the upper outer wall of the bearing belt.

[0008] It is worth noting that the limiting frame can support the limiting wheel, which can cooperate with the lower inner wall of the bearing seat to clamp and limit the bearing belt, and ensure that the bearing belt can move along the inner walls of the front and rear ends of the bearing seat, thereby ensuring the smooth movement of the bearing belt and avoiding wrinkles and jamming of the bearing belt.

[0009] Preferably, the upper end of the limiting frame is provided with a protective plate, the lower end of the protective plate is provided with symmetrical slots, and the upper end of the limiting frame is fixedly connected with a locking block, which is compatible with the slots.

[0010] It is worth noting that the protective plate can be fixed to the upper end of the limit frame by using the slot and the locking block to protect the carrier belt and paper label. The protective plate fixed by the locking block can be easily removed. When needed, the protective plate can be quickly removed to level the carrier belt or improve the convenience of carrier belt installation.

[0011] Preferably, a rotating frame is fixedly connected to the lower edge of the protective plate, and a limiting roller is rotatably installed on the inner wall of the front and rear ends of the rotating frame, with the outer wall of the limiting roller conforming to the upper outer wall of the bearing belt.

[0012] It is worth noting that the limiting roller can be supported by the rotating frame. The limiting roller can flatten the carrying belt and limit the carrying belt to the lower inner wall of the carrying seat, and also ensure the smooth movement of the carrying belt.

[0013] Preferably, the upper end of the protective plate has an observation port.

[0014] It is worth noting that the viewing port allows for easy observation of the paper label's condition and facilitates writing on the paper label.

[0015] Preferably, a rotating frame two is fixedly connected to the lower edge of the bearing seat, and a flattening roller is rotatably installed on the inner wall of the front and rear ends of the rotating frame two, and a soft pad is fixedly connected to the outer wall of the flattening roller.

[0016] It is worth noting that the flattening roller can be supported by the rotating frame. After the labeling is completed, the paper label can be flattened by the flattening roller to ensure the firmness of the paper label. The soft pad fixed to the outer wall of the flattening roller can prevent damage to the paper label.

[0017] Preferably, the outer walls of the rotating roller, clamping roller one, and clamping roller two are all fixed with anti-slip pads.

[0018] It is worth noting that the anti-slip pads ensure the stability of the rotating roller during rotation, preventing slippage that could affect the labeling quality. The anti-slip pads fixed to the outer walls of clamping roller one and clamping roller two ensure the stability of clamping, preventing slippage that could cause the carrier belt to move and jam, and ensuring smooth labeling.

[0019] Preferably, gear two and gear three have the same number of teeth.

[0020] It is worth noting that by having the same number of teeth as gear two and gear three, the transmission ratio between gear two and gear three can be ensured to be one, thereby keeping clamping roller one and clamping roller two in synchronous reverse motion, ensuring that clamping roller one and clamping roller two synchronously pull the upper and lower outer walls of the carrying belt.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This invention uses a carrier component to limit the movement of the conveyor component, a carrier seat to support and limit the carrier belt, and a bonding frame whose lower end can be bonded to the paper surface. Pressing the bonding frame onto the paper surface allows it to slide, pressing the carrier belt against the paper surface. As the bonding frame slides, the rotating rollers on the paper surface rotate, causing pulley one to drive pulley two to rotate in the same direction via a belt. The rotation of pulley two drives gear one to mesh with gear two, which in turn meshes with gear three to rotate synchronously in opposite directions. This causes clamping rollers one and two to pull the carrier belt. When the carrier belt moves the paper label to the edge of the bonding frame, the cone angle of the bonding frame causes one end of the paper label to detach from the carrier belt and adhere to the paper surface. Continuing to move the carrier seat allows all the paper labels to be pasted on the paper surface. During movement, the rotating rollers can initially flatten the paper labels, ensuring labeling quality. Attached Figure Description

Detailed Implementation

[0029] Among the feasible methods discovered in this field for assisting in label placement on archives, there are template-based solutions. This method involves creating a positioning template that matches the archive specifications, with cutout areas corresponding to the label size. When labeling, staff first flatten the template over the pre-defined labeling position on the archive, then hold the label and align it with the cutout area, thus reducing label misalignment and offset caused by visual bias during manual labeling. The core advantage of this positioning template is its simple structure, low production cost, and lack of additional power support, making it suitable for small-scale label placement in small-scale archive management scenarios. However, this method still relies on manually picking up and placing labels one by one. When facing large-volume labeling needs, staff must repeatedly perform the repetitive actions of "picking up labels - aligning with cutouts - pressing and pasting," resulting in high labor intensity, fatigue, and low overall work efficiency. Furthermore, the template size must strictly match the archive specifications; when the archive size or thickness changes, a new template must be made, resulting in poor versatility and an inability to flexibly adapt to different types of archive labeling needs.

[0030] Among the feasible methods discovered in this field, there are mechanical peeling schemes utilizing rigid edges for the peeling of labels from the carrier tape. This method involves setting a rigid peeling plate or peeling roller with a specific angle along the tape's transport path. When the tape carrying the label passes the peeling edge at a preset speed, the tape is forcibly bent at the peeling edge. Because the adhesive force between the label and the tape is less than the adhesion force between the label and the labeling substrate (such as archival paper), the label separates from the tape at the bend and adheres to the archival surface under the action of a subsequent guiding structure. This mechanical peeling method does not rely on changes in adhesion or other auxiliary means, has a relatively simple structure, and can achieve continuous label peeling. However, this method has strict requirements on the peeling angle. If the peeling angle is too large, the label is prone to wrinkling or corner lifting during the peeling process; if the peeling angle is too small, the label may not peel completely, and some labels may still adhere to the tape. Furthermore, this method has limited adaptability, only achieving stable peeling for labels of specific thicknesses and materials. For thinner or less adhesive labels, peeling failure or label damage is likely to occur.

[0031] Among the existing feasible technologies for post-labeling reinforcement, there is an auxiliary structure based on roller flattening. This technology places a flattening roller behind the labeling station. When a labeled document passes under the flattening roller, the roller rolls on the document surface, applying uniform pressure through its own weight or additional pressure. This removes air between the label and the document, preventing air bubbles and enhancing adhesion, preventing labels from peeling off later. Traditional flattening rollers are mostly made of metal or rigid plastic, offering high structural stability and providing stable pressure. However, these rigid rollers can easily cause indentations or damage to thinner, less robust documents. Furthermore, the roller pressure is usually a fixed value and cannot be adjusted according to the document material (e.g., kraft paper, coated paper) or the label's adhesiveness. With strongly adhesive labels, excessive pressure can cause adhesive overflow at the label edges, contaminating the document surface; with weakly adhesive labels, insufficient pressure fails to achieve the desired reinforcement effect.

[0032] Among the existing feasible technologies for label protection and status monitoring, there exists an auxiliary structure based on a transparent protective cover. This technology places a transparent protective cover above the label-bearing area. The cover, made of materials such as acrylic or transparent plastic, effectively prevents dust, impurities, and other contaminants from contacting the label surface, avoiding contamination during storage or transportation. Simultaneously, staff can directly observe the number, arrangement, and remaining status of labels through the transparent cover, facilitating timely label replenishment or handling of abnormalities. Traditional transparent protective covers are mostly fixedly installed, such as by screws or clips to the main body of the device. When it is necessary to replace the carrier tape or adjust the label position, multiple fixing components must be disassembled, which is inconvenient. Furthermore, the gap between the cover and the carrier tape is difficult to precisely control. If the gap is too large, contaminants may still enter the protected area; if the gap is too small, the cover is prone to friction with the tape surface, leading to tape wear or label detachment, affecting the lifespan of the device and the labeling effect.

[0033] 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.

[0034] To address the problems of cumbersome manual label removal, low efficiency in large-scale operations, and easy contamination of the label pasting surface in existing technologies, the following technical solution is proposed. Please refer to [link / reference]. Figures 1-5 ;

[0035] The document label quick-application auxiliary card includes a support component, which includes a support base 101. A labeling component is mounted on the outer wall of the support base 101. The labeling component includes an adhesive frame 201 fixed to the left edge of the support base 101. Rotating rollers 202 are rotatably mounted on the inner walls of the front and rear ends of the adhesive frame 201. The outer wall of the rotating rollers 202 is flush with the lower edge of the adhesive frame 201. The rotating shaft of the rotating rollers 202 passes through the inner wall of the adhesive frame 201 and is fixedly connected to a pulley 203. A second pulley 204 is rotatably mounted on the front end of the support base 101. The first pulley 203 and the second pulley 204 are connected by a belt. A gear 205 is fixedly connected to the outer wall of the rotating shaft of the second pulley 204. A third rotating frame 208 is fixedly connected to the lower end of the support base 101. The front of the third rotating frame 208... The inner walls at both ends are rotatably mounted with clamping rollers 209 and 210 distributed vertically. The shaft of clamping roller 209 passes through the front end of rotating frame 208 and is fixedly connected to gear 206. The shaft of clamping roller 210 passes through the front end of rotating frame 208 and is fixedly connected to gear 207. Gear 1 205 meshes with gear 2 206, and gear 2 206 meshes with gear 207. The bearing assembly is also equipped with a conveying assembly, which includes a bearing belt 301 disposed on the inner wall of the lower end of the bearing seat 101. The bearing belt 301 passes between rotating roller 202 and bonding frame 201. The end of the bearing belt 301 is located between clamping roller 209 and clamping roller 210. Several paper labels 302 are affixed to the outer wall of the bearing belt 301 at equal intervals.

[0036] The carrier component can limit the movement of the conveyor component. The carrier seat 101 can support and limit the carrier belt 301. The lower end of the bonding frame 201 can be bonded to the paper surface. Pressing the bonding frame 201 to slide against the paper surface allows the bonding frame 201 to press the carrier belt 301 against the paper surface. When the bonding frame 201 slides, the rotating roller 202 against the paper surface can rotate, thereby causing the pulley 1 203 to drive the pulley 204 to rotate in the same direction via the belt. After the pulley 204 rotates, it can drive the gear 1 205 to mesh with the gear 206 to rotate, thereby causing the gear to rotate. The gear 206 meshes with the gear 207 and rotates synchronously in opposite directions, causing the clamping roller 209 and clamping roller 210 to pull the carrier belt 301 to move. When the carrier belt 301 moves the paper label 302 to the edge of the bonding frame 201, the cone angle of the bonding frame 201 will cause one end of the paper label 302 to fall off the carrier belt 301 and stick the paper label 302 to the paper surface. Continuing to move the carrier seat 101 can make the paper label 302 completely stick to the paper surface. During the movement, the rotating roller 202 can initially flatten the paper label 302 to ensure the labeling quality.

[0037] Please see Figure 3A symmetrically positioned limiting frame 102 is fixed to the upper edge of the bearing seat 101. Several equidistant limiting wheels 103 are rotatably mounted on the inner wall of the limiting frame 102. The outer wall of the limiting wheel 103 is in contact with the upper outer wall of the bearing belt 301. The limiting frame 102 can support the limiting wheel 103. The limiting wheel 103 can cooperate with the lower inner wall of the bearing seat 101 to clamp and limit the bearing belt 301, and ensure that the bearing belt 301 can move along the inner walls of the front and rear ends of the bearing seat 101, thereby ensuring the smooth movement of the bearing belt 301 and avoiding wrinkles and jamming of the bearing belt 301. The upper end of the limiting frame 102 is provided with a protective plate 105, and the lower end of the protective plate 105 is provided with symmetrical front and rear slots 106. The upper end of the limiting frame 102 is fixed with a locking block 104, which is compatible with the slots 106. The protective plate 105 can be fixed to the upper end of the limiting frame 102 by the cooperation of the slots 106 and the locking block 104, so as to protect the carrier belt 301 and the paper label 302. The protective plate 105 fixed by the locking block 104 can be easily disassembled. When needed, the protective plate 105 can be quickly disassembled to level the carrier belt 301 or improve the ease of installation of the carrier belt 301.

[0038] A rotating frame 108 is fixedly connected to the lower edge of the protective plate 105. Limiting rollers 109 are rotatably installed on the inner walls of the front and rear ends of the rotating frame 108. The outer wall of the limiting rollers 109 is in contact with the upper outer wall of the carrying belt 301. The rotating frame 108 can support the limiting rollers 109, which can flatten the carrying belt 301 and limit the carrying belt 301 to the lower inner wall of the carrying seat 101, and also ensure the smooth movement of the carrying belt 301. An observation port 107 is provided through the upper end of the protective plate 105. The state of the paper label 302 can be easily observed through the observation port 107, and writing can be easily done on the paper label 302.

[0039] A rotating frame 110 is fixedly connected to the lower edge of the support seat 101. A flattening roller 111 is rotatably installed on the inner wall of the front and rear ends of the rotating frame 110. A soft pad is fixedly connected to the outer wall of the flattening roller 111. The rotating frame 110 can support the flattening roller 111. After the labeling is completed, the paper label 302 can be flattened by the flattening roller 111 to ensure the firmness of the paper label 302. The soft pad fixed to the outer wall of the flattening roller 111 can prevent damage to the paper label 302.

[0040] Please see Figure 4Anti-slip pads are fixed to the outer walls of the rotating roller 202, clamping roller 1 209, and clamping roller 210. The anti-slip pads ensure the stability of the rotating roller 202 during rotation and prevent slippage that could affect the labeling quality. The anti-slip pads fixed to the outer walls of clamping roller 1 209 and clamping roller 210 ensure the stability of the clamping and prevent slippage that could cause the carrier belt 301 to move and jam, thus ensuring smooth labeling. Gear 2 206 and gear 3 207 have the same number of teeth. The fact that gear 2 206 and gear 3 207 have the same number of teeth ensures that the transmission ratio of gear 2 206 and gear 3 207 is one, thereby keeping clamping roller 1 209 and clamping roller 210 moving synchronously in opposite directions and ensuring that clamping roller 1 209 and clamping roller 210 pull the upper and lower outer walls of the carrier belt 301 synchronously.

[0041] Working principle: Before use, the carrier belt 301 with the paper label 302 pasted on it is installed in the carrier seat 101, so that the carrier belt 301 passes between the rotating roller 202 and the bonding frame 201, and the end is placed between the clamping roller 1 209 and the clamping roller 210. At this time, the limiting wheel 103 on the limiting frame 102 cooperates with the lower inner wall of the carrier seat 101 to clamp and limit the carrier belt 301. The protective plate 105 is fixed to the upper end of the limiting frame 102 through the card block 104 and the card slot 106. The limiting roller 109 at its lower end further flattens the carrier belt 301, ensuring that the carrier belt 301 is flat and can move smoothly. At the same time, the protective plate 105 protects the carrier belt 301 and the paper label 302. The status of the paper label 302 can be observed or written on through the observation port 107.

[0042] During operation, the lower edge of the bonding frame 201 is bonded to the paper to be labeled, and the bearing seat 101 is pressed, causing the bonding frame 201 to slide along the paper surface. At this time, the rotating roller 202 is passively rotated due to its contact with the paper surface. The anti-slip pad on its outer wall ensures stable rotation without slippage. The rotation of the rotating roller 202 drives the pulley 1 203 to rotate synchronously. The pulley 1 203 drives the pulley 204 to rotate in the same direction via a belt, which in turn drives the gear 1 205 to rotate. The gear 1 205 meshes with the gear 206, causing... When gear 206 rotates, since gear 206 and gear 3 207 have the same number of teeth and mesh with each other, they rotate synchronously in opposite directions, driving clamping roller 1 209 and clamping roller 210 to rotate synchronously in opposite directions. The anti-slip pads on the outer walls of clamping roller 1 209 and clamping roller 210 ensure stable clamping of the carrying belt 301, thereby pulling the carrying belt 301 to move along the inner wall of the carrying seat 101 (limiting wheel 103 and limiting roller 109 ensure smooth movement of the carrying belt 301 and avoid wrinkles and jamming).

[0043] When the carrier belt 301 moves the paper label 302 to the edge of the bonding frame 201, the conical structure of the bonding frame 201 causes one end of the paper label 302 to separate from the carrier belt 301 and adhere to the paper surface. As the carrier seat 101 continues to move, the paper label 302 gradually and completely detaches from the carrier belt 301 and adheres to the paper surface. During this process, the rotating roller 202 initially flattens the newly adhered paper label 302. After the labeling is completed, the flattening roller 111 at the lower end of the carrier seat 101 moves with the device, and the soft pad on its outer wall flattens the paper label 302 a second time to ensure that the paper label 302 is firmly and flat, thus completing the entire labeling process.
