[0002] With the rapid development of the economy, labels are widely used on commodities. Currently, most labels are printed on label backing paper, and after the label printing is completed, the label needs to be die-cut.

[0003] Some existing label feeding devices cannot flexibly and accurately adjust the tension of the labels according to factors such as the material, thickness, and feeding speed of the labels. This can easily lead to problems such as loosening, wrinkling, or overstretching of the labels during feeding, affecting the subsequent die-cutting accuracy and the overall quality of the labels. Therefore, we need to propose a die-cutting anti-loosening clamping device. Utility Model Content

[0016] 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.

[0017] Please see Figure 1-4 This utility model provides a technical solution: A die-cutting anti-loosening clamping device includes: a workbench 1; a clamping and cutting mechanism 2, installed at the center of the surface of the workbench 1, for clamping and cutting labels; and a material guiding and tensioning mechanism 3, two sets of which are symmetrically arranged and installed on both sides of the clamping and cutting mechanism 2, for guiding and tensioning the labels before and after cutting. By setting the symmetrically distributed material guiding and tensioning mechanism 3 in cooperation with the centrally located clamping and cutting mechanism 2, the device achieves the effect of improving the continuity of label conveying and preventing label deviation during the cutting process. In an optional embodiment: the material guiding tensioning mechanism 3 includes a mounting frame 31; the mounting frame 31 is fixedly installed on the top of the workbench 1, and two sets of material guiding rollers 32 are symmetrically and rotatably installed on the inner walls of both sides of the mounting frame 31. An electric hydraulic rod 33 is fixedly installed on the bottom inner side of the mounting frame 31, and a concave frame 34 is fixedly installed on the top of the telescopic end of the electric hydraulic rod 33 through a connecting plate. A tensioning roller 35 is rotatably installed inside the concave frame 34. The height of the tensioning roller 35 is adjusted by driving the electric hydraulic rod 33, which is used to adjust the tension force when guiding the label with the two sets of material guiding rollers 32.

[0018] It should be noted that by setting an electric hydraulic rod 33 to drive a height-adjustable tension roller 35, which works in conjunction with a fixed-position guide roller 32 to form a triangular support and guiding structure, the tension can be flexibly adjusted according to the label material (such as paper or film) and thickness, thus preventing the label from wrinkling or breaking.

[0019] In an optional embodiment: the clamping and cutting mechanism 2 includes a cutting table 21; the cutting table 21 is fixedly installed on the top of the workbench 1, and a fixing frame 23 is fixedly installed on the top of the cutting table 21. Three sets of T-shaped rods 24 are equidistantly slidably inserted into the top of the fixing frame 23. A first spring 25 is sleeved between two sets of T-shaped rods 24 and the top of the fixing frame 23. A drive assembly is connected to the top of the other set of T-shaped rods 24. A mounting plate 26 is fixedly connected to the bottom of the three sets of T-shaped rods 24. A die-cutting cutter 27 is fixedly installed at the bottom of the mounting plate 26.

[0020] It should be noted that by setting three sets of equidistantly distributed T-shaped rods 24 to synchronously support the mounting plate 26, and with the first springs 25 on both sides providing reset buffer force, the effect of ensuring smooth lifting and lowering of the die-cutting cutter 27 and reducing cutting impact is achieved.

[0021] In an optional embodiment: the drive assembly includes a fixed housing 211; the fixed housing 211 is fixedly mounted on the top of the fixed frame 23, and a cam 212 is rotatably mounted inside the fixed housing 211 via a rotating shaft, and one end of the rotating shaft passes through the fixed housing 211 and is fixedly connected to a drive motor 213, and the cam 212 is in contact with the top of a set of T-shaped rods 24 located in the middle.

[0022] It should be noted that by setting the cam 212 transmission structure in conjunction with the drive motor 213, the rotational motion is converted into the up-and-down reciprocating linear motion of the T-shaped rod 24, thereby achieving the effect of high-frequency and stable cutting operation of the die-cutting tool 27.

[0023] In an optional embodiment: a cam groove 214 is fixedly installed on the top of a set of T-shaped rods 24 located in the middle, and the interior of the cam groove 214 fits against the cam 212.

[0024] It should be noted that by setting a cam groove 214 that matches the contour of cam 212, the contact area between cam 212 and T-shaped rod 24 is increased, which achieves the effect of avoiding slippage during transmission and improving the stability of power transmission.

[0025] In an optional embodiment: the clamping and cutting mechanism 2 further includes a clamping assembly; the clamping assembly includes a U-shaped clamping plate 28, which is located below the die-cutting cutter 27. Four sets of telescopic rods 29 are symmetrically fixedly installed on the top of the U-shaped clamping plate 28. The top of the four sets of telescopic rods 29 are fixedly connected to the bottom of the mounting plate 26. A second spring 210 is sleeved on the outer wall of the telescopic rod 29. The two ends of the second spring 210 abut against one side of the mounting plate 26 and the U-shaped clamping plate 28, respectively, to provide clamping buffer force for the U-shaped clamping plate 28.

[0026] It should be noted that by setting four sets of symmetrically distributed telescopic rods 29 in conjunction with the second spring 210, an elastic pressing structure is formed, which achieves the effect of flexibly pressing the label before cutting and avoiding damage to the label due to hard squeezing.

[0027] In an optional embodiment: the inner wall of the U-shaped clamping plate 28 is slidably connected to the outer wall of the die-cutting tool 27, and the top surface of the cutting table 21 is provided with a die-cutting groove 22 corresponding to the die-cutting tool 27.

[0028] It should be noted that by setting the sliding fit between the U-shaped clamping plate 28 and the die-cutting cutter 27, and the die-cutting groove 22 adapted to the cutter, the effect of ensuring neat cutting edges and avoiding burrs during label cutting is achieved.

[0029] In an optional embodiment, auxiliary rollers 215 are rotatably mounted on both sides of the cutting table 21 via brackets, and the top of the auxiliary rollers 215 is flush with the top of the cutting table 21 for assisting in the conveying of labels.

[0030] It should be noted that by setting an auxiliary roller 215 that is flush with the top surface of the cutting table 21, the height difference between the labels at the inlet and outlet of the cutting table 21 is eliminated, thereby reducing the label conveying resistance and preventing label scratches.

[0031] In an optional embodiment: both ends of the concave frame 34 are fixedly installed with limit sliders 36, and both sides of the mounting frame 31 are provided with limit grooves 37 that are adapted to the limit sliders 36. One end of the limit slider 36 is slidably connected to the inside of the limit groove 37.

[0032] It should be noted that by setting the sliding cooperation between the limiting slider 36 and the limiting groove 37, the lifting trajectory of the concave frame 34 is restricted, thereby avoiding the deviation of the tension roller 35 during lifting and ensuring that the tension force is evenly transmitted to the label.

[0033] Working principle: First, the label to be cut is inserted sequentially through the bottom of the guide roller 32, the top of the tension roller 35, and the guide roller 32 of the material tensioning mechanism 3 on one side, passes through the auxiliary rollers 215 on both sides of the cutting table 21, and finally exits through the guide roller 32 of the material tensioning mechanism 3 on the other side; the electric hydraulic rod 33 is activated to adjust the height of the tension roller 35 according to the material and thickness of the label, so that the label is in a suitable tension state, and the limiting slider 36 slides synchronously in the limiting groove 37 to ensure that the tension roller 35 moves smoothly and avoids the label from wrinkling or breaking; When the drive motor 213 is started, the drive motor 213 drives the cam 212 to rotate in the fixed housing 211. The cam 212 pushes the middle T-shaped rod 24 downward through the cam groove 214. The three sets of T-shaped rods 24 synchronously drive the mounting plate 26 and the die-cutting cutter 27 to descend. During the descent, the U-shaped clamping plate 28 first contacts the label on the cutting table 21. As the mounting plate 26 continues to descend, the telescopic rod 29 retracts, the second spring 210 is compressed and generates elastic clamping force, which firmly fixes the label on the cutting table 21, achieving flexible clamping and preventing the label from shifting or being damaged. As the mounting plate 26 continues to descend, the die-cutting blade 27 passes through the inner wall of the U-shaped clamping plate 28 and cooperates with the die-cutting groove 22 on the cutting table 21 to complete the label cutting. After the cutting is completed, the drive motor 213 drives the cam 212 to continue to rotate. The downward pressure of the cam 212 on the T-shaped rod 24 disappears, and the first springs 25 on both sides elastically return to their original positions, driving the T-shaped rod 24, the mounting plate 26 and the die-cutting blade 27 to return to their original positions. At the same time, the second spring 210 pushes the U-shaped clamping plate 28 to return to its original position, releasing the cut label.

[0034] The control method in this application is through a controller. The controller's control circuit can be implemented by a person skilled in the art through simple programming and is common knowledge in the field. Furthermore, since this application is mainly used to protect the structure, shape, and their combination, this application will not explain the control method and circuit connection in detail.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
