Description

Technical Field

[0001] This utility model relates to the field of label die-cutting technology, specifically to an automatic die-cutting correction device. Background Technology

[0002] Self-adhesive labels are labels with adhesive on the back, allowing users to easily peel them off and stick them to various surfaces. They are widely used in product packaging, logistics, commercial signage, advertising, product manuals, and other fields. Due to their ease of use, wide applicability, and the fact that they require no additional tools, self-adhesive labels have gained widespread use in modern society.

[0003] Self-adhesive labels require the use of a die-cutting device. This device cuts the printed self-adhesive label material into the designed shape. The die-cutting device not only cuts the label outline but can also perform marking, creasing, and other processes as needed, ensuring the quality of the finished labels and meeting usage requirements.

[0004] However, current traditional die-cutting devices cannot be adjusted according to the width of the label, which causes the label to easily shift during the conveying process, resulting in low product quality. Furthermore, they cannot correct the shifted labels, which presents certain defects. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an automatic die-cutting correction device, which has the advantages of being able to adjust according to the width of the label and correcting labels that have shifted. This solves the problems of current die-cutting devices not being able to adjust according to the width of the label, which leads to easy shifting and the inability to correct offset labels.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an automatic die-cutting correction device, comprising a back plate, a calibration component, and an auxiliary component. A conveying roller, a stabilizing roller, and a transmission roller are fixed on the back plate. The stabilizing roller is located between the conveying roller and the transmission roller, and the stabilizing roller and the transmission roller are arranged opposite to each other. The conveying roller is arranged parallel to the stabilizing roller and the transmission roller below. The conveying roller, the stabilizing roller, and the transmission roller rotate synchronously to realize the conveying operation of the label strip.

[0009] Label strips are wound around the conveying rollers. The label strips are movably connected to the stabilizing rollers and the drive rollers. When the conveying rollers rotate, the label strips on the sides are conveyed outwards and transmitted through the stabilizing rollers and the drive rollers.

[0010] An annular groove is provided on the back plate, located on the side of the stabilizing roller. A movable strip is slidably connected in the annular groove, and a calibration component for correcting the position of the label strip is installed on the movable strip. When the movable strip slides in the annular groove, the position of the calibration component and the auxiliary component can be adjusted.

[0011] The calibration assembly includes two sets of calibrators arranged opposite each other. The calibrators are attached to the side of the label strip, and the two sets of calibrators are respectively attached to both sides of the label strip to achieve stable delivery of the label strip and to correct the label strip that has deviated.

[0012] The calibrator has auxiliary components positioned opposite each other at its top and bottom, which are used to tighten excessive labels.

[0013] This automatic die-cutting correction device corrects the deviation of self-adhesive product labels by mounting rolls of label strips onto conveyor rollers, with the front end of the label strips mounted on stabilizing rollers and drive rollers, and the side of the label strips adhering between two sets of calibrators. By controlling the synchronous rotation of three rollers, the label strips are conveyed. During conveying, the connecting plate rotates on the side plate, causing the auxiliary roller to adhere to the side of the label strip and tighten it. Simultaneously, when deviation occurs, the rotating roller moves up and down under the elastic force of the tension spring to correct and guide the label strip until the front end of the label strip adheres to the corresponding position on the side of the rotating roller.

[0014] As a further improvement to the above solution, the calibrator consists of a side plate and a rotating roller. The side plate has an installation groove, and the rotating roller is rotatably connected in the installation groove.

[0015] With the above technical solution, two rotating rollers are vertically installed in the mounting groove. The side of the rotating roller protrudes from the opposite side of the side plate, thus fully fitting the side of the label strip.

[0016] As a further improvement to the above solution, a calibration groove is provided on the rotating roller, and the calibration groove is attached to the side of the label strip.

[0017] With the above technical solution, an annular calibration groove is opened on the side of the rotating roller. The calibration groove is designed with an open shape, so that the opening is smaller at the depth of the calibration groove. As a result, when the label strip is attached to the calibration groove, it moves further into the calibration groove, making the horizontal height position of the label strip more accurate.

[0018] As a further improvement to the above solution, tension springs are installed at both ends of the rotating roller, and the tension springs are fitted between the mounting groove and the rotating roller.

[0019] With the above technical solution, the tension springs have the same length, and in a static state, the horizontal height of the calibration grooves opened on the rotating rollers is the same. When the label strip deviates, the elastic force of the tension springs enables the automatic calibration of the label strip height.

[0020] As a further improvement to the above solution, the auxiliary component includes a connecting plate movably connected to the top and bottom of the side plate, with a sleeve hole provided on the connecting plate, and an auxiliary roller movably sleeved in the sleeve hole.

[0021] Through the above technical solution, the connecting plate drives the side plate to move on the side of the auxiliary roller, so that the two sets of calibrators can be adjusted according to the width of the label strip, thus satisfying the function of calibrating label strips of different widths.

[0022] As a further improvement to the above solution, the auxiliary roller is provided with an adjustment groove, and a positioning screw is threadedly connected to the connecting plate. The positioning screw passes through the sleeve hole and fits into the adjustment groove.

[0023] Through the above technical solution, the connecting plate slides on the side of the auxiliary roller to adjust according to the width of the label strip. The front end of the positioning screw is attached to the corresponding adjustment groove to fix the adjusted spacing and ensure the stability of the label strip correction.

[0024] As a further improvement to the above solution, sliders are provided at both the top and bottom of the side plate, and grooves are provided on the opposite surfaces of the connecting plates at both ends of the side plate, with the sliders slidably connected in the grooves.

[0025] The above technical solution allows for adjustment of the tilt angle of the auxiliary roller by sliding the slider within the corresponding groove, thereby tightening the loose label strip.

[0026] As a further improvement to the above solution, an arc-shaped tube is installed on the connecting plate at both ends of the side plate, and a connecting button is provided at both ends of the arc-shaped tube. At the same time, a connecting block is provided on the side of the connecting plate, and the connecting button is threaded into the connecting block.

[0027] Through the above technical solution, the arc-shaped tube is used to connect the two connecting plates at the top and bottom of the side plate, thus preventing the side plate from detaching from the connecting plate.

[0028] As a further improvement to the above solution, the side of the side plate is fixed to the moving strip.

[0029] Through the above technical solution, the moving strip slides in the annular groove, realizing the overall position adjustment of the calibration component around the transmission roller, so that the two auxiliary rollers are inclined and attached to the side of the label strip, and the loose label strip is pressed.

[0030] As a further improvement to the above solution, the opposite surface of the side plate is provided with a clearance groove, which is horizontally opposite to the calibration groove.

[0031] Through the above technical solution, the clearance groove is designed in the shape of "<", and the openings of the two side plates are set opposite to each other, so that the depth of the clearance groove corresponds horizontally with the calibration groove, thereby enabling the side of the label strip to be stably attached to the calibration groove.

[0032] Compared with the prior art, the present invention provides an automatic die-cutting correction device, which has the following beneficial effects:

[0033] 1. This automatic die-cutting correction device moves the connecting plates at both ends of the calibration component to the side of the auxiliary roller, and makes the front end of the positioning screw fit into the corresponding adjustment groove. This allows it to be adjusted according to the width of the label, so that the side of the label strip fits into the calibration groove of the rotating roller, ensuring the stability of the label conveying.

[0034] 2. This die-cutting automatic correction device rotates the connecting plate on the side of the edge plate until the auxiliary roller presses the loose label strip. At the same time, when the label has a height deviation, the elastic force of the tension spring automatically corrects the height of the label strip, further improving the practicality of the device.

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.

[0045] Example 1

[0046] Please see Figures 1-4 As shown, the automatic die-cutting correction device proposed in this embodiment includes a back plate 1, a calibration component 2, and an auxiliary component 3. A conveying roller 101, a stabilizing roller 103, and a transmission roller 104 are fixed on the back plate 1. The stabilizing roller 103 is located between the conveying roller 101 and the transmission roller 104, and the stabilizing roller 103 and the transmission roller 104 are arranged opposite to each other. The conveying roller 101 is arranged parallel to the bottom of the stabilizing roller 103 and the transmission roller 104. The conveying roller 101, the stabilizing roller 103, and the transmission roller 104 rotate synchronously to realize the conveying operation of the label strip 102.

[0047] A label strip 102 is wound on the conveyor roller 101. The label strip 102 is movably connected to the stabilizing roller 103 and the drive roller 104. When the conveyor roller 101 rotates, the label strip 102 on the side is conveyed outward and transmitted through the stabilizing roller 103 and the drive roller 104.

[0048] An annular groove 105 is provided on the back plate 1. The annular groove 105 is located on the side of the stabilizing roller 103. A moving strip 106 is slidably connected in the annular groove 105. A calibration component 2 for position correction of the label strip 102 is installed on the moving strip 106. When the moving strip 106 slides in the annular groove 105, the position of the calibration component 2 and the auxiliary component 3 can be adjusted.

[0049] The calibration component 2 includes two sets of calibrators 21 arranged opposite to each other. The calibrators 21 are attached to the side of the label strip 102. The two sets of calibrators 21 are respectively attached to both sides of the label strip 102 to achieve stable delivery of the label strip 102 and to correct the label strip 102 that has deviated.

[0050] The top and bottom of the calibrator 21 are provided with auxiliary components 3, which are used to tighten the excessive output of the label strips 102.

[0051] The working principle of the automatic die-cutting correction device proposed in this embodiment is as follows: In use, the rolled label strip 102 is fitted onto the conveying roller 101, and the front end of the label strip 102 is fitted onto the stabilizing roller 103 and the transmission roller 104. The side of the label strip 102 is attached between the two sets of calibrators 21. By controlling the synchronous rotation of the three rollers, the label strip 102 is conveyed. During conveying, the connecting plate 301 rotates on the side plate 201, so that the auxiliary roller 304 is attached to the side of the label strip 102 to tighten the label strip 102. At the same time, when a deviation occurs, the rotating roller 203 moves up and down under the elastic force of the tension spring 205 to correct and guide the label strip 102 until the front end of the label strip 102 is attached to the corresponding position on the side of the transmission roller 104.

[0052] Example 2

[0053] Please see Figures 1-4 As shown, the automatic die-cutting correction device proposed in this embodiment, based on Embodiment 1, further includes a calibrator 21 composed of a side plate 201 and a rotating roller 203. The side plate 201 has a mounting groove 202, within which the rotating roller 203 is rotatably connected. The rotating roller 203 has a calibration groove 204, which is attached to the side of the label strip 102. Tension springs 205 are installed at both ends of the rotating roller 203, fitting between the mounting groove 202 and the rotating roller 203. The auxiliary component 3 includes a connecting plate 301 movably connected to the top and bottom of the side plate 201. A sleeve hole 302 is provided on the connecting plate 301, within which an auxiliary roller 304 is movably fitted. The auxiliary roller 304 has an adjustment groove 30. 5. Simultaneously, a positioning screw 303 is threadedly connected to the connecting plate 301. The positioning screw 303 passes through the sleeve hole 302 and fits into the adjusting groove 305. Slider 2011 is provided at the top and bottom of the side plate 201. At the same time, the opposite surfaces of the connecting plates 301 at both ends of the side plate 201 are provided with sliding grooves 3011. The slider 2011 is slidably connected in the sliding grooves 3011. Arc-shaped tubes 4 are installed on the connecting plates 301 at both ends of the side plate 201. Connecting buttons 401 are provided at both ends of the arc-shaped tubes 4. At the same time, connecting blocks 306 are provided on the side of the connecting plate 301. The connecting buttons 401 are threadedly connected in the connecting blocks 306. The side of the side plate 201 is fixed on the moving bar 106. A clearance groove 206 is provided on the opposite surface of the side plate 201. The clearance groove 206 is horizontally opposite to the calibration groove 204.

[0054] In this design, two rotating rollers 203 are vertically installed in the mounting groove 202. The sides of the rotating rollers 203 protrude from the opposite side of the side plate 201, thus fully fitting the side of the label strip 102. An annular calibration groove 204 is formed on the side of the rotating rollers 203. The calibration groove 204 has an open design, making the opening smaller at its depth. Therefore, when the label strip 102 is fitted into the calibration groove 204, it moves deeper into the groove, resulting in a more accurate horizontal position for the label strip 102. A tension spring 205... With consistent lengths, the calibration slots 204 on the rotating roller 203 are at the same horizontal height when stationary. When the label strip 102 shifts, the elastic force of the tension spring 205 automatically calibrates its height. The connecting plate 301 moves the side plate 201 to the side of the auxiliary roller 304, allowing the two sets of calibrators 21 to be adjusted according to the width of the label strip 102, thus calibrating label strips 102 of different widths. The connecting plate 301 is located on the side of the auxiliary roller 304. The sliding mechanism allows for adjustment based on the width of the label strip 102. The positioning screw 303, with its front end fitting into the corresponding adjustment groove 305, secures the adjusted spacing, ensuring the stability of the label strip 102's correction. The slider 2011 slides within the corresponding groove 3011, adjusting the tilt angle of the auxiliary roller 304 to tighten any loose label strip 102. The arc-shaped tube 4 connects the two connecting plates 301 at the top and bottom of the side plate 201, preventing the side plate 201 from... 01. After the connecting plate 301 is disengaged, the moving strip 106 slides in the annular groove 105, realizing the overall position adjustment of the calibration component 2 around the transmission roller 104. This allows the two auxiliary rollers 304 to be inclined and attached to the side of the label strip 102, pressing the loose label strip 102. The clearance groove 206 is designed in the shape of "<", and the openings of the two side plates 201 are set opposite to each other, so that the depth of the clearance groove 206 corresponds horizontally to the calibration groove 204, thereby allowing the side of the label strip 102 to be stably attached to the calibration groove 204.

[0055] 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.
