Description

Technical Field

[0001] This utility model belongs to the technical field of fabric labeling devices, specifically relating to a foldable fabric labeling device. Background Technology

[0002] After the printed and dyed fabrics are processed, they need to be folded due to their large size. Labels are also affixed to the fabrics to provide information. Figure 1 The diagram illustrates one folding procedure for the fabric: fold the fabric along its two long sides, then fold the two wide sides towards the center, and finally fold the two wide sides together again. After folding, attach labels to both sides of the folds. This both attaches a label to the fabric and seals the folds, preventing the fabric from unraveling later.

[0003] Currently, labeling the folds of fabrics is mostly done manually, which is costly and inefficient. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a foldable fabric labeling device.

[0005] To achieve the above objectives, this utility model discloses a foldable fabric labeling device, including a belt conveyor mechanism with at least two belts for jointly conveying fabric and a labeling mechanism.

[0006] Two adjacent belts are spaced apart to form a gap, and the width of the gap is not less than the width of the label;

[0007] The labeling mechanism includes a connecting plate, an unwinding roller, a peeling plate, a winding roller, and a label pressing assembly. The unwinding roller, the peeling plate, and the winding roller are all fixedly connected to the connecting plate. The bottom surface of the peeling plate is the peeling surface, which is spaced apart from the belt and opposite to the gap.

[0008] The label pressing assembly includes an upper label pressing assembly and a lower label pressing assembly. The upper label pressing assembly includes a first connector and an upper pressure roller. One end of the first connector is fixedly connected to the connecting plate, and the other end of the first connector is rotatably connected to the upper pressure roller. The upper pressure roller is located behind the label peeling plate and is positioned opposite to the gap. The lower label pressing assembly includes a second connector and a lower pressure roller. One end of the second connector is fixed, and the other end of the second connector is rotatably connected to the lower pressure roller. The lower pressure roller is located below the upper pressure roller. The distances between the upper pressure roller and the belt and the lower pressure roller are adapted to the thickness of the folded fabric to be labeled.

[0009] Preferably, the lower pressure roller is located directly below the upper pressure roller.

[0010] Preferably, the vertical extension surface of the label-peeling surface is tangent to the upper pressure roller and the lower pressure roller.

[0011] Preferably, the first connector includes a connecting block, a connecting shaft, and a connecting strip. The connecting block is fixedly connected to the connecting plate, the connecting shaft is rotatably connected to the connecting block, and the connecting strip is slidably connected to the connecting shaft along its own length.

[0012] Preferably, it also includes a fabric pressing mechanism located on the front side of the labeling structure. The fabric pressing mechanism includes two sets of fabric pressing components, which are respectively located on both sides of the belt conveyor mechanism in the conveying direction.

[0013] Each of the pressing components includes an upper and lower drive device and a pressing component. The pressing component is mounted on the upper and lower drive device and moves up and down under the drive of the upper and lower drive device.

[0014] Preferably, the pressing assembly includes a connecting frame and pressing rollers. The connecting frame is fixedly connected to the upper and lower driving devices, and the pressing rollers are rotatably connected to the connecting frame. The central axis of the pressing rollers is perpendicular to the conveying direction of the belt conveyor mechanism. There are multiple pressing rollers, and the multiple pressing rollers are arranged along the conveying direction.

[0015] Preferably, the two sets of pressing cloth assemblies are located on both sides of the label peeling plate, and the rear end of each set of pressing cloth assemblies extends at least to be flush with the upper pressure roller.

[0016] Preferably, the label peeling plate has a vertically arranged waist-shaped hole, and the label peeling plate is connected to the connecting plate by screws.

[0017] The labeling process of this folded fabric labeling device is as follows: The folded edge of the fabric (the fold between the two wide sides) faces the labeling mechanism, and then it is placed on a belt conveyor. The belt conveys the fabric towards the labeling mechanism. During the conveying process, the labeling mechanism operates, and the label, under the action of the peeling plate, extends downwards and separates from the backing paper, with the bottom of the label extending below the belt's bearing surface. The belt continues to convey, moving the fabric to its side to contact and adhere the label. Then, as the fabric continues to move, the label completely detaches from the backing paper. Then, under the action of the upper and lower pressure rollers, the portions of the label located above and below the fabric are pressed onto the top and bottom surfaces of the fabric by the upper and lower pressure rollers, respectively, finally affixing the label to the folded edge of the fabric.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] The label is separated from the backing paper by a label peeler. The fabric is then conveyed by a belt conveyor to the point where it comes into contact with the label. Under the action of the upper and lower pressure rollers, the upper and lower parts of the label are pressed onto the top and bottom surfaces of the fabric, achieving automatic labeling at the folds of the fabric without manual operation, reducing labor costs and improving labeling efficiency.

[0020] The distances between the upper pressure roller and the belt, as well as the lower pressure roller, are all adapted to the thickness of the folded fabric to be labeled. This ensures that the upper and lower pressure rollers can press down on the top and bottom surfaces of the fabric, making the label firmly adhered to the fabric and improving the labeling quality.

[0021] The belt conveyor mechanism has two adjacent belts spaced apart to form a gap. The width of the gap is not less than the width of the label. This provides space for the label to extend downwards, allowing it to reach the position opposite the pressure roller and thus adhere to the bottom of the fabric. Attached Figure Description

[0034] Fabric 400; Labels 500. Detailed Implementation

[0035] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] A foldable fabric labeling device, see Figures 2-9 It includes a belt conveyor mechanism 100 with at least two belts 110 for jointly conveying the fabric and a labeling mechanism 200, both of which are mounted on a workbench (not shown in the figure).

[0037] The belt conveyor mechanism 100 adopts a conventional double belt conveyor, which has two belts 110 to jointly transport the fabric. The two adjacent belts 110 are spaced apart to form a gap, the width of which is not less than the width of the label. This provides space for the subsequent labels to extend downwards for labeling.

[0038] The belt conveyor mechanism 100 generally includes a support plate 120 that supports the belt 110. The support plate 120 supports the belt 110, thus effectively supporting the fabric 400. The gap between the two belts 110 is designed to allow the label 500 to extend downwards. It is understood that the support plate 120 is positioned through the labeling mechanism 200 and the gap between the two belts 110 to prevent the support plate 120 from interfering with the label extension.

[0039] The labeling mechanism 200 includes a connecting plate 210, an unwinding roller 220, a peeling plate 230, a rewinding roller 240, and a label pressing assembly 250. The unwinding roller 220, peeling plate 230, and rewinding roller 240 are all fixedly connected to the connecting plate 210. The unwinding roller 220 is used to load the label roll, and the rewinding roller 240 is used to load the backing paper roll. The direction from the unwinding roller to the rewinding roller is opposite to the conveying direction of the belt 110. The peeling plate 230 is vertically arranged, with its bottom width gradually decreasing downwards, thus making its bottom surface the peeling surface 231. Each individual label on the label roll separates from the backing paper after moving to the peeling surface 231. The peeling surface 231 is spaced apart from the belt 110 to avoid interference with the fabric on the belt 110. The peeling surface 231 is also positioned opposite the gap between the two belts 110, allowing the labels to extend downwards.

[0040] The label pressing assembly 250 includes an upper label pressing assembly 260 and a lower label pressing assembly 270. The upper label pressing assembly 260 includes a first connecting member 261 and an upper pressure roller 262. One end of the first connecting member 261 is fixedly connected to the connecting plate 210, and the other end of the first connecting member 261 is rotatably connected to the upper pressure roller 262. The upper pressure roller 262 is located behind the label peeling plate 230 (the side along the conveying direction of the belt 110 is the rear, and the opposite direction is the front) and is disposed opposite to the aforementioned gap. The lower label pressing assembly 270 includes a second connecting member 271 and a lower pressure roller 272. The second connecting member 271... One end is fixed, specifically on the workbench, and the other end of the second connector 271 is rotatably connected to the lower pressure roller 272. The lower pressure roller 272 is located below the upper pressure roller 262. The distance between the upper pressure roller 262 and the belt 110, and the distance between the upper pressure roller 262 and the lower pressure roller 272 are adapted to the thickness of the folded fabric to be labeled, preferably slightly smaller than the thickness of the folded fabric to be labeled, so that the upper pressure roller 262 and the lower pressure roller 272 can press on the top and bottom surfaces of the fabric, so that the label is firmly pasted on the fabric, improving the labeling quality, while not affecting the fabric conveying.

[0041] The labeling process of the labeling mechanism 200 is as follows: The folded edge of the fabric (the fold between the two wide sides) faces the labeling mechanism 200, and then it is placed on the belt conveyor mechanism 100. The belt conveyor mechanism 100 conveys the fabric towards the labeling mechanism 200. During the conveying process, the labeling mechanism 200 operates, and under the action of the peeling plate 230, most of the label extends downward and separates from the backing paper, with the bottom of the label extending below the bearing surface of the belt 110. The belt conveyor mechanism 100 continues to convey, moving the fabric to its side to contact and adhere the label. Then, as the fabric continues to move, the label completely detaches from the backing paper. Then, under the action of the upper pressure roller 262 and the lower pressure roller 272, the portions of the label located above and below the fabric are pressed onto the top and bottom surfaces of the fabric by the upper pressure roller 262 and the lower pressure roller 272, respectively, finally affixing the label to the folded edge of the fabric.

[0042] In this embodiment, the upper pressure roller 262 and the lower pressure roller 272 are of the same size and specifications. The lower pressure roller 272 is located directly below the upper pressure roller 262. The upper pressure roller 262 and the lower pressure roller 272 apply pressure to the fabric at the same projection position, so the force is uniform and avoids the problem of displacement and wrinkles caused by uneven force.

[0043] The vertical extension of the label peeling surface 231 is tangent to the upper pressure roller 262 and the lower pressure roller 272. In this way, when the label is peeled off from the backing paper, it directly enters the pressing trajectory of the pressure roller, avoiding label skewing due to gravity and displacement after the label is peeled off, thus greatly improving the labeling position accuracy.

[0044] In this embodiment, the first connector 261 and the second connector 271 have the same structure. The first connector 261 will be described below.

[0045] The first connecting component 261 includes a connecting block 2611, a connecting shaft 2612, and a connecting strip 2613. The connecting block 2611 is fixedly connected to the connecting plate 210, the connecting shaft 2612 is rotatably connected to the connecting block 2611, and the connecting strip 2613 is vertically arranged and can slide along its length to the connecting shaft 2612. By rotating the connecting shaft 2612 and sliding the connecting strip 2613 up and down, the distance between the upper pressure roller 262 and the belt 110, as well as the distance between the upper pressure roller 262 and the label peeling plate 230, can be adjusted to accommodate folded fabrics of different thicknesses, thus broadening the applicability of the device.

[0046] The connecting block 2611 is fixedly connected to a fixing clamp 280. The fixing clamp 280 has an opening that communicates with the shaft hole of the connecting shaft 2612. The opening is locked with bolts to lock the connecting shaft 2612. After the upper pressure roller 262 is adjusted to the correct position, the rotation of the connecting shaft 2612 is restricted. The top of the connecting strip 2613 has a waist-shaped hole 2614 extending along its length. The end of the connecting shaft 2612 away from the connecting block 2611 is slidably inserted into the waist-shaped hole 2614. The connecting strip 2613 can slide along the waist-shaped hole 2614 and is fixed to the connecting shaft 2612 by bolts.

[0047] If the fabric is not fully compressed after folding, it will arch and bounce, which will affect the reliability of subsequent labeling. In this embodiment, the device also includes a fabric pressing mechanism 300 and a sensor located in front of the labeling mechanism 200. The fabric pressing mechanism 300 includes two sets of fabric pressing assemblies 310, which are respectively located on both sides of the belt conveyor mechanism 100 in the conveying direction to press the fabric on both sides. When the sensor detects the fabric, it sends a signal to put the fabric pressing mechanism 300 into working state. The two sets of fabric pressing assemblies 310 have the same structure; one set will be described below.

[0048] The fabric pressing assembly 310 includes an up-and-down driving device 311 and a fabric pressing assembly 320. The up-and-down driving device 311 includes a cylinder 3111, a first connecting piece 3112, guide posts 3113, a spring 3114, and a second connecting piece 3115. The first connecting piece 3112 is mounted on the output end of the cylinder 3111. There are two guide posts 3113, which are slidably connected to the first connecting piece 3112. A limiting component, such as a bolt, is connected to the top of each guide post 3113, thereby limiting its movement against the top surface of the first connecting piece 3112 and preventing it from falling off. The bottom ends of the two guide posts 3113 are fixedly connected to the second connecting piece 3115. Each guide post 3113 is fitted with the aforementioned spring 3114, and both ends of the spring 3114 abut against the first connecting piece 3112 and the second connecting piece 3115. The fabric pressing assembly 320 is fixedly connected to the bottom of the second connecting piece 3115. When the sensor detects the fabric, the cylinder 3111 pushes the first connecting piece 3112 downward, causing the fabric pressing assembly 320 to slightly press the folded side of the fabric (the downward pressure is configured not to affect the fabric conveying). The guide post 3113 has the ability to move up and down and is held in place by the spring 3114, and the contact between the fabric pressing assembly 320 and the fabric is elastic.

[0049] To ensure proper fabric transport, the fabric pressing assembly 320 includes a connecting frame 321 and pressing rollers 322. The connecting frame 321 is fixedly connected to the bottom of the second connecting piece 3115, and the pressing rollers 322 are rotatably connected to the connecting frame 321. The central axis of the pressing rollers 322 is perpendicular to the transport direction of the belt conveyor mechanism 100. There are multiple pressing rollers 322, arranged along the transport direction. The pressing rollers 322 are rotatable and can rotate when in contact with the fabric during transport, thus avoiding interference with fabric transport.

[0050] In this embodiment, two sets of fabric pressing assemblies 310 are located on both sides of the label peeling plate 230. The rear end of each set of fabric pressing assemblies 310 extends at least to be flush with the upper pressure roller 262, specifically extending to the rear side of the upper pressure roller 262. In this way, when the fabric moves to the labeling mechanism 200 for labeling, both sides of the fabric can still be pressed down, ensuring that the fabric can pass smoothly between the upper pressure roller 262 and the lower pressure roller 272, thus ensuring the reliability of the labeling process.

[0051] The above description is only a preferred embodiment of the present utility model, and its structure is not limited to the shapes listed above. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
