Description

Technical Field

[0001] This utility model belongs to the field of labeling machine technology, and relates to a label-removing structure for a labeling machine on a mesh substrate. Background Technology

[0002] Typical disc-shaped coating molds, known as "elastic grinding discs (louvers)," primarily adhere abrasive or cloth to a substrate. During operation, the substrate carries the abrasive and rotates to grind the workpiece. Currently, these products utilize a multi-layered resin-coated fiberglass mesh substrate, also known as a fiberglass mesh substrate or a circular mesh substrate sheet.

[0003] In the production process of circular mesh substrate sheets, it is necessary to affix trademarks to the circular mesh substrate sheets to facilitate the display of information such as workpiece model. With the continuous increase in production speed, the requirements for the labeling speed of existing labeling machines are getting higher and higher. Relying solely on manual labeling can no longer meet the needs of society, and most of the labeling work is repetitive, which is very harmful to the workers' health. Therefore, a label-grabbing structure for labeling machines that can easily grasp label materials is needed to solve the above problems. Utility Model Content

[0020] 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.

[0021] The following is in conjunction with the appendix Figures 1 to 3 The specific embodiments of this utility model will be described in further detail.

[0022] Depend on Figures 1 to 3 As shown, this utility model includes a first fixed frame 1, a second fixed frame 2, and a through rod 3 for storing label materials. In order to facilitate single-sheet feeding of labels, the bottom of the through rod 3 is detachably connected to the second fixed frame 2. A limiting piece 4 is slidably fitted on the outer side of the through rod 3. A friction mechanism 5 for friction limiting of the material is provided in the middle of the second fixed frame 2. A label transfer mechanism 6 for transferring and conveying labels is provided on the upper side of the first fixed frame 1.

[0023] It should be noted that the second fixing frame 2 is also equipped with a lifting mechanism inside, which is used to lift the limiting piece 4 upward, thereby driving the label material on the upper side of the limiting piece 4 to move upward, such as the lifting mechanism disclosed in the announcement number CN211195060U, which will not be described in detail here; the first fixing frame 1 and the second fixing frame 2 are both fixed on the machine body of the mesh substrate forming machine, so that the positions of the first fixing frame 1 and the second fixing frame 2 are relatively fixed. The mesh substrate forming machine is used to produce fiber matrix mesh substrate;

[0024] In use, the label material can be placed on the upper side of the limiting plate 4, and the through rod 3 can be passed through the middle of the label material to complete the label feeding. At this time, under the action of the lifting mechanism, the limiting plate 4 can be used to lift the label to a suitable height. The label transfer mechanism 6 will then adsorb the label paper and transport it horizontally to the work station. During the label adsorption process, by setting the friction mechanism 5, the label transfer mechanism 6 can move only one label at a time, reducing the probability of label sticking caused by air pressure adsorption.

[0025] Furthermore, by Figures 1 to 3 As shown, in order to be able to adapt to different sizes of label paper for use, the friction mechanism 5 includes two connecting rods 7 and two friction brushes 8. Each connecting rod 7 is detachably connected to the second fixed frame 2. Each connecting rod 7 has a fixed plate 9 detachably connected to the side away from the second fixed frame 2. Each friction brush 8 is disposed between the fixed plate 9 and the corresponding connecting rod 7.

[0026] In use, by setting the friction brush 8, each label is lifted by the lifting mechanism, and its edge is subjected to downward frictional resistance provided by the friction brush 8, thereby reducing the probability of two adjacent labels sticking together due to air pressure adsorption. In addition, in actual use, the material, bristle length, and bristle width of the friction brush 8 can be adjusted according to the actual situation, such as bristle brush, rubber brush, etc., so that it can match the material of the label paper and obtain good friction. It will not be described in detail here. The position of the friction brush 8 can be fixed by the clamping action between the fixing plate 9 and the connecting rod 7.

[0027] Furthermore, by Figures 1 to 3 As shown, in order to facilitate the adjustment of the distance between the two friction brushes 8, multiple adjustment holes 10 are provided on the upper side of the second fixing frame 2, and an adjustment groove 11 is provided on the side of each connecting rod 7 near the second fixing frame 2. The adjustment groove 11 and the corresponding adjustment hole 10 cooperate with each other to form a structure in which the position and angle of the connecting rod 7 are adjustable.

[0028] In use, the two connecting rods 7 can be connected to the corresponding adjusting holes 10 by bolts. By tightening the bolts, the angle and position of the corresponding connecting rods 7 can be fixed, thereby fixing the position of the corresponding friction brushes 8. The above design allows for easy adjustment of the distance between the two friction brushes 8, thus adapting to labels with different outer diameters.

[0029] Furthermore, by Figures 1 to 3 As shown, in order to facilitate the disassembly and replacement of the friction brush 8, the connecting rod 7 is provided with multiple countersunk holes 12 near the fixing plate 9, and each fixing plate 9 is provided with a threaded hole near the countersunk hole 12.

[0030] In use, the bolt can be passed through the countersunk hole 12 and engaged with the corresponding threaded hole. This allows the fixing plate 9 and the connecting rod 7 to be fastened together, making it convenient for the two to clamp and fix the friction brush 8 and to disassemble, inspect and replace it in a timely manner.

[0031] Furthermore, by Figures 1 to 3 As shown, in order to increase the service life of the device, a flexible sleeve 13 is threadedly connected to the top of the through rod 3, and multiple deformation grooves 14 are provided on the flexible sleeve 13.

[0032] Furthermore, by Figures 1 to 3 As shown, in order to achieve a better label adsorption effect, the label transfer mechanism 6 includes a sliding block 15 that can move left and right and a cylinder 16 fixedly connected to the end of the sliding block 15. The moving end of the cylinder 16 is fixedly connected to an adsorption frame 17. The adsorption frame 17 is provided with multiple adsorption slots 18. Each adsorption slot 18 can be detachably connected to a vacuum suction cup 19.

[0033] In use, when the label transfer mechanism 6 is operating, the adsorption frame 17 will move up and down under the drive of the cylinder 16, so that the vacuum suction cup 19 can adsorb the label. During the descent of the adsorption frame 17, if the limit of the cylinder 16 fails, the deformation groove 14 can generate corresponding deformation under the action of the flexible sleeve 13, which can buffer the rod 3 and the adsorption frame 17. After the adsorption frame 17 completes the descent and rise process, the vacuum suction cup 19 has adsorbed the label material on the lower side of the adsorption frame 17, and the sliding block 15 will move left and right, thereby driving the label to the unloading station through the adsorption frame 17 and the vacuum suction cup 19 to put the label down.

[0034] It should be noted that each vacuum suction cup 19 has a vacuum tube connected to its upper side, and the other end of the vacuum tube is connected to a negative pressure generator, so that each vacuum suction cup 19 can perform adsorption at the loading station and maintain the adsorption state until the unloading station, where the label paper is placed in the appropriate position at the unloading station.

[0035] Furthermore, by Figures 1 to 3 As shown, in order to make the label movement more stable, a guide plate 20 is fixedly connected to the upper side of the first fixed frame 1. A guide block 21 is fixedly connected to the side of the guide plate 20 near the sliding block 15. The sliding block 15 and the guide block 21 are connected by a slide rail, which is a ball slide rail. The left and right sides of the guide block 21 are respectively rotatably connected to the drive wheel 23 and the synchronous wheel 22. A synchronous belt 24 is provided on the outer side of the drive wheel 23 and the synchronous wheel 22.

[0036] It should be noted that both the driving pulley 23 and the synchronous pulley 22 are synchronous toothed pulleys, and the synchronous belt 24 is a synchronous toothed belt, which enables the driving pulley 23 and the synchronous pulley 22 to rotate synchronously.

[0037] Furthermore, by Figures 1 to 3 As shown, to facilitate maintenance of the sliding block 15, a motor 25 is fixedly connected to the side of the guide plate 20 away from the drive wheel 23. The output shaft of the motor 25 passes through the guide plate 20 and is coaxially fixedly connected to the drive wheel 23. The bottom of the sliding block 15 is fixedly connected to the timing belt 24. A disassembly plate is provided on the lower side of the sliding block 15. The timing belt 24 is located between the disassembly plate and the sliding block 15. The disassembly plate and the sliding block 15 are connected by bolts. Specifically, the middle of the corresponding bolt passes through the disassembly plate and the timing belt 24 and is threadedly connected to the sliding block 15.

[0038] It should be noted that motor 25 is a servo motor 25, which can perform reciprocating motion and has a built-in controller (such as a PLC controller) that can control its rotation direction, rotation speed, and start and stop time. It will not be described in detail here. Cylinder 16 is existing technology. It is connected to an air source connection pipe to drive the output end of cylinder 16 to move. It will not be described in detail here.

[0039] When in use, after starting the motor 25, the output shaft of the motor 25 drives the synchronous belt 24 to reciprocate through the drive wheel 23 and the synchronous wheel 22, which in turn drives the sliding block 15 to reciprocate, thereby realizing the feeding of the label.

[0040] When using this utility model, the label material can first be placed on the upper side of the limiting piece 4, and the through rod 3 can be passed through the middle of the label material to complete the label feeding. At this time, under the action of the lifting mechanism, the limiting piece 4 can be used to lift the label to a suitable height. The label transfer mechanism 6 will then adsorb the label paper and transport it horizontally to the work station. During the label adsorption process, by setting the friction mechanism 5, the label transfer mechanism 6 can move only one label at a time, reducing the probability of label sticking caused by air pressure adsorption.

[0041] This utility model features a novel structure, ingenious design, and simple and convenient operation. This design effectively facilitates single-sheet label feeding, enabling the device to adapt to different sizes of label paper. It also facilitates adjustment of the distance between the two friction brushes 8, makes disassembly and replacement of the friction brushes 8 easier, increases the device's service life, achieves better label adsorption, makes label movement more stable, and facilitates device maintenance.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
