A self-adhesive label die-cutting machine

Abstract

This utility model relates to the field of self-adhesive label production technology and discloses a self-adhesive label die-cutting machine, including: a worktable and self-adhesive labels. A support plate is fixedly installed on the top of the worktable, and an adjustment component is provided between the support plate and the worktable. This equipment solves the problem of "easy deviation and easy deformation" of self-adhesive label substrates through an adaptive feeding structure of "spring buffer - anti-slip damping - double roller traction," ensuring feeding stability. Regarding the adaptability of the pressing material, the anti-slip roller of the compression component adopts a "spring groove - sliding block" buffer design: the spring groove is fixed to the bottom of the support plate, and the inner second sliding block is connected to the inner wall of the sliding block through a spring. When self-adhesive substrates of different thicknesses pass through, the spring can adaptively extend and retract according to the substrate thickness, pushing the second sliding block to drive the anti-slip roller to make slight adjustments up and down, always maintaining appropriate pressure on the substrate surface, thus avoiding excessive pressure that could cause substrate deformation.

Description

Technical Field

[0001] This utility model relates to the field of self-adhesive label production, specifically to a self-adhesive label die-cutting machine. Background Technology

[0002] In the field of self-adhesive label production, die-cutting machines, as core post-processing equipment, undertake the crucial task of accurately cutting the printed self-adhesive substrate (including the backing paper and label layer) into preset shapes (such as circles, rectangles, and irregular shapes). Their die-cutting accuracy directly determines the finished product pass rate and subsequent labeling efficiency. However, existing self-adhesive label die-cutting machines have many technical limitations in practical applications, making it difficult to simultaneously meet the dual requirements of "high-precision cutting" and "stable feeding." Specific problems are as follows:

[0003] On the one hand, die-cutting precision is low and error control is difficult. Traditional die-cutting machines mostly adopt a structure of "single cylinder driving the cutter + fixed guide rail", which can only achieve unidirectional linear motion of the cutter and cannot make micro-distance adjustments according to the dimensional deviations of the self-adhesive label (such as substrate stretching and positioning offset after printing). For example, when self-adhesive labels need to be cut into small irregular shapes (such as round labels with a diameter <10mm), the positioning error of the cutter of traditional equipment can reach 0.5-1mm, far exceeding the industry-allowed precision standard of 0.1mm, resulting in a large number of labels being scrapped due to "rough edges" and "oversized dimensions", with a pass rate of only 80%-85%. At the same time, traditional equipment lacks a linkage adjustment mechanism. If it is necessary to cut the horizontal and vertical dimensions at the same time, it is necessary to adjust twice, which is cumbersome and prone to secondary errors, and cannot meet the requirements of "one-time positioning and two-way cutting" in mass production.

[0004] On the other hand, poor feeding stability leads to label misalignment. Self-adhesive label substrates are characterized by their thinness and stickiness. Traditional die-cutting machines often use a single-roller traction system without a pressure device. During feeding, the substrate is prone to slippage or wrinkling due to roller speed fluctuations and adhesive sticking. While some machines add pressure rollers, these rollers are designed with a fixed height, making them unsuitable for self-adhesive substrates of varying thicknesses (e.g., 80μm-200μm label layers). Excessively thick substrates are easily deformed, while thin substrates are not firmly pressed, leading to misalignment. Furthermore, traditional feeding structures lack damping control, causing substrates to "jump" due to inertia at high speeds (e.g., 30m / min), further exacerbating die-cutting positioning errors and severely impacting production efficiency.

[0005] These shortcomings result in existing die-cutting machines having significant deficiencies in the coordination between "high-precision die-cutting" and "stable feeding," making it difficult to adapt to the production needs of modern self-adhesive labels that are "small in size, high in precision, and in large in volume." This limitation is even more pronounced in fields with stringent precision requirements, such as electronic labels and pharmaceutical labels. Therefore, there is an urgent need for a self-adhesive label die-cutting machine that combines "micro-distance linkage adjustment" and "adaptive stable feeding." Utility Model Content

[0011] A sliding rod is slidably connected to both sides of the inner wall of the first sliding block; a dual-axis motor is fixedly installed on the top of the first sliding block, and small connecting rods are fixedly installed on the output ends of the dual-axis motors respectively. The other end of the small connecting rod is movably connected to a large connecting rod, and the other end of the large connecting rod is movably connected to the outer wall of the sliding rod.

[0012] Preferably, the linkage specifically includes: an adjustment platform, which is fixedly connected to the bottom of the slide rod;

[0013] The cylinder is fixedly installed on the top of the adjustment platform; the mounting base is fixedly installed on the bottom of the adjustment platform.

[0014] A fixing block is fixedly installed on both the front and back of the adjustment platform. A connecting rod is fixedly connected between the fixing block and one side of the fixing seat. A cross slide rod is fixedly connected to the output end of the cylinder. The other end of the cross slide rod passes through the top of the adjustment platform and extends to the bottom of the adjustment platform. A cutter is fixedly installed at the bottom of the cross slide rod. Both sides of the cross slide rod are movably sleeved on the connecting rod. A limit groove is fixedly installed on the front of the cross slide rod, and a rack is fixedly installed on the back of the cross slide rod.

[0015] Preferably, a fixing block 2 is fixedly installed on both the front and back of the adjustment platform. A connecting rod 2 is fixedly connected between the fixing block 2 and the other side of the fixing seat. A T-shaped slide rod is movably sleeved on the outer wall of the connecting rod 2. A rack 2 is fixedly installed on the front of the T-shaped slide rod, and a limit groove 2 is fixedly installed on the back of the T-shaped slide rod. A cutter 2 is fixedly installed at the bottom of the T-shaped slide rod.

[0016] Preferably, a gear is movably connected to the bottom of the fixed base; rack one and rack two are meshed with the gear, and the other ends of rack one and rack two extend into limiting groove one and limiting groove two, respectively.

[0017] Preferably, the compression assembly specifically includes: a second support plate, which is fixedly installed on the top of the workbench; spring grooves are fixedly installed on both sides of the bottom of the second support plate; a sliding groove is opened at the bottom of the spring groove, and a second sliding block is slidably connected inside the sliding groove; a spring is fixedly connected between one side of the second sliding block and the inner wall of the sliding groove; an anti-slip roller is movably connected to the other side of the second sliding block; a support rod is fixedly connected to the back of the workbench; rollers are equidistantly connected to the surface of the support rod; the rollers and the anti-slip rollers are in contact with the self-adhesive label; there are two rollers; the self-adhesive label surrounds the first roller and is wrapped around the second roller.

[0018] This utility model provides a self-adhesive label die-cutting machine. It has the following beneficial effects:

[0019] 1. This self-adhesive label die-cutting machine utilizes a dual-layer adjustment design of "telescopic part - linkage part" to achieve "up-down reciprocating cutting + left-right micro-distance linkage adjustment" of the cutter, significantly improving die-cutting accuracy and effectively controlling dimensional errors. Regarding the cutting drive, the telescopic part adopts a "dual-axis motor - linkage transmission" structure: the dual-axis motor is fixed to the top of the first slide block, and its output end drives the large connecting rod to swing via a small connecting rod, thereby driving the slide rod to move up and down reciprocally along the inner wall of the first slide block; the bottom of the slide rod is fixed to the adjustment platform, which can synchronously drive the linkage part to rise and fall as a whole, realizing the up-and-down cutting action of cutter one and cutter two, avoiding the "jerking" feeling of traditional single-cylinder drive, and improving cutting stability by 60%.

[0020] 2. Regarding micro-distance adjustment, the linkage unit innovatively designs a "cylinder-rack-gear" linkage mechanism: the cylinder output pushes the cross slide bar to slide left and right along connecting rod one; rack one on the back of the cross slide bar meshes with the gear at the bottom of the fixed base, driving the gear to rotate; the gear further meshes with rack two on the front of the T-shaped slide bar, causing the T-shaped slide bar to slide in the opposite direction along connecting rod two, realizing bidirectional linkage adjustment of "cross slide bar-cutter one" and "T-shaped slide bar-cutter two". At the same time, limiting groove one and limiting groove two respectively limit the movement trajectory of rack one and rack two, avoiding excessive adjustment that could cause gear disengagement, ultimately controlling the die-cutting error within 0.08mm, increasing the label qualification rate to over 98%, and meeting the high-precision cutting requirements of small-sized and irregularly shaped labels.

[0021] 3. This equipment solves the problems of "easy deviation and easy deformation" of self-adhesive label substrates through an adaptive feeding structure of "spring buffer - anti-slip damping - double roller traction," ensuring feeding stability. Regarding the adaptability of the pressing material, the anti-slip rollers of the compression component adopt a "spring groove - sliding block" buffer design: the spring groove is fixed to the bottom of the second support plate, and the inner second sliding block is connected to the inner wall of the sliding block through a spring. When self-adhesive substrates of different thicknesses pass through, the spring can adaptively extend and retract according to the substrate thickness, pushing the second sliding block to drive the anti-slip rollers to make slight adjustments up and down, always maintaining appropriate pressure on the substrate surface. This avoids both excessive pressure causing substrate deformation and excessively loose pressing leading to slippage.

[0022] 4. In terms of feeding stability, the double rollers and anti-slip rollers work together: the two rollers on the support rod are arranged in an "alternating" manner. The self-adhesive substrate first passes around the first roller to achieve "initial traction", and then wraps around the second roller for "secondary tensioning", forming a stable feeding path. At the same time, the surface of the anti-slip roller is made of rubber, which generates moderate damping on the substrate, offsetting the inertial impact force during high-speed feeding and avoiding the "material shoving" phenomenon.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] Example 1

[0031] A preferred embodiment of the self-adhesive label die-cutting machine provided by this utility model is, for example... Figure 1-4 As shown: A self-adhesive label die-cutting machine includes: a worktable 1 and self-adhesive labels 5. A support plate 2 is fixedly installed on the top of the worktable 1. An adjustment component 3 is provided between the support plate 2 and the worktable 1. A compression component 4 is provided on the top of the worktable 1.

[0032] The adjustment component 3 specifically includes: a telescopic part 31, which is disposed on one side of the support plate 2; and a linkage part 32, which is disposed on the top right side of the workbench 1.

[0033] The telescopic part 31 specifically includes: a first sliding block 311, which is fixedly installed on one side of the support plate 2; a sliding rod 313, which is slidably connected to both sides of the inner wall of the first sliding block 311; a dual-axis motor 312 is fixedly installed on the top of the first sliding block 311, and small connecting rods 314 are fixedly installed on the output ends of the dual-axis motor 312 respectively. The other end of the small connecting rod 314 is movably connected to a large connecting rod 315, and the other end of the large connecting rod 315 is movably connected to the outer wall of the sliding rod 313.

[0034] The linkage unit 32 specifically includes: an adjustment platform 321, fixedly connected to the bottom of the slide rod 313; a cylinder 322, fixedly installed on the top of the adjustment platform 321; a fixing seat 325, fixedly installed on the bottom of the adjustment platform 321; fixing blocks 326 are fixedly installed on both the front and back of the adjustment platform 321; a connecting rod 327 is fixedly connected between the fixing block 326 and one side of the fixing seat 325; a cross slide rod 323 is fixedly connected to the output end of the cylinder 322; the other end of the cross slide rod 323 passes through the top of the adjustment platform 321 and extends to the bottom of the adjustment platform 321; a cutter 324 is fixedly installed on the bottom of the cross slide rod 323; both sides of the cross slide rod 323 are movably sleeved on the connecting rod 327; a limit groove 328 is fixedly installed on the front of the cross slide rod 323; and a rack 329 is fixedly installed on the back of the cross slide rod 323. The adjustment platform 321 has a fixing block 3211 fixedly installed on both its front and back sides. A connecting rod 3212 is fixedly connected between the fixing block 3211 and the other side of the fixing seat 325. A T-shaped slide rod 3213 is movably sleeved on the outer wall of the connecting rod 3212. A rack 3214 is fixedly installed on the front of the T-shaped slide rod 3213, and a limiting groove 3215 is fixedly installed on the back of the T-shaped slide rod 3213.

The rack 329 and rack 3214 mesh with the gear 3216, and the other ends of the rack 329 and rack 3214 extend into the limiting groove 3215 and limiting groove 328, respectively.

[0035] In this embodiment, the precision of the cutter is achieved by adjusting component 3. The dual-axis motor 312 drives the slide bar 313 to move up and down reciprocally through the connecting rod, and the slide bar 313 is fixedly connected to the linkage part 32, so that the dual-axis motor 312 drives the linkage part 32 to cut up and down. The cylinder 322 can adjust the cross slide bar 323 and the T-shaped slide bar 3213 by a small distance to the left and right. The rack 1 329 drives the rack 2 3214 to rotate through the gear 3216 to achieve a linkage response, thereby reducing errors.

[0036] Example 2

[0037] Based on Example 1, a preferred embodiment of the self-adhesive label die-cutting machine provided by this utility model is as follows: Figure 1-4 As shown: The compression component 4 specifically includes: a second support plate 411, which is fixedly installed on the top of the workbench 1. Spring grooves 412 are fixedly installed on both sides of the bottom of the second support plate 411. A sliding groove is opened at the bottom of the spring groove 412, and a second sliding block 414 is slidably connected inside the sliding groove. A spring 413 is fixedly connected between one side of the second sliding block 414 and the inner wall of the sliding groove. An anti-slip roller 415 is movably connected to the other side of the second sliding block 414. Support rods 416 are fixedly connected to the back of the workbench 1. Rollers 417 are equidistantly connected to the surface of the support rods 416. The rollers 417 and the anti-slip rollers 415 are in contact with the self-adhesive labels 5. There are two rollers 417. The self-adhesive labels 5 surround the first roller and are wrapped around the second roller.

[0038] In this embodiment, the compression component 4 is used to limit the offset of the self-adhesive label 5. The retractable anti-slip roller 415 can meet the needs of self-adhesive labels 5 with different thicknesses. The anti-slip roller also plays a damping role for the self-adhesive label 5. In addition, an anti-deviation disc is installed on the edge of the roller, thereby reducing the phenomenon of self-adhesive label 5 deviation.

[0039] Working principle: First, the equipment is initialized and the substrate is clamped: Check whether the support plate 1 2 and support plate 2 411 on the top of the workbench 1 are stable, and ensure that there are no loose parts in the adjustment component 3 and the compression component 4; Install the roll of self-adhesive label 5 (including the backing paper and label layer) on the feeding rack (not shown) on one side of the workbench 1, and pull the substrate through the double roller 417 and anti-slip roller 415 of the compression component 4 in sequence - the substrate first passes around the first roller 417, and then wraps around the second roller 417 to form a "double roller traction" path; at this time, the anti-slip roller 415 adapts to the surface of the substrate under the elastic force of the spring 413, generating appropriate pressure to complete the feeding preparation.

[0040] Based on the preset cutting dimensions of the self-adhesive label 5 (e.g., a rectangular label with a horizontal width of 15mm and a vertical width of 10mm), activate the adjustment component 3 to position the cutter:

[0041] Up and down cutting stroke adjustment: Start the dual-axis motor 312 of the telescopic part 31. The motor output drives the small connecting rod 314 to rotate. The small connecting rod 314 pushes the slide rod 313 to slide up and down along the inner wall of the first slide block 311 through the hinged large connecting rod 315. The adjustment platform 321 at the bottom of the slide rod 313 rises and falls synchronously with it, driving the first cutter 324 and the second cutter 3217 of the linkage part 32 to adjust to a suitable distance from the surface of the substrate (usually 0.1-0.2mm), ensuring that the label layer can be cut off without damaging the backing paper during cutting.

[0042] Left and right micro-distance linkage adjustment: If a lateral offset is detected in the self-adhesive label 5 (such as dimensional deviation caused by substrate stretching after printing), the cylinder 322 at the top of the adjustment platform 321 is activated. The cylinder output pushes the cross slide bar 323 to slide to the right along the connecting rod 1 327 (adjustment amount 0.5mm); the rack 1 329 on the back of the cross slide bar 323 meshes with the gear 3216 at the bottom of the fixed seat 325, causing the gear 3216 to rotate clockwise; the gear 3216 further drives the meshing rack 2 3214, causing the T-shaped slide bar 3213 to slide to the left along the connecting rod 2 3212 (adjustment amount 0.5mm), realizing the bidirectional linkage adjustment of cutter 1 (lateral cutting) and cutter 2 (longitudinal cutting) to compensate for substrate offset error; during the adjustment process, the limiting groove 1 328 and the limiting groove 2 3215 respectively limit the movement range of rack 1 and rack 2 to prevent gear disengagement.

[0043] After the die-cutting adjustments are complete, start the equipment for batch cutting:

[0044] Feeding Traction: The double rollers 417 rotate synchronously under the drive of the drive motor (not shown), pulling the self-adhesive label 5 to be conveyed to the die-cutting area at a preset speed (such as 30m / min); the anti-slip rollers 415 use the damping force generated by the surface rubber material to counteract the inertial impact of the substrate and ensure stable feeding speed; at the same time, the springs 413 continuously and adaptively adjust the height of the anti-slip rollers to adapt to changes in substrate thickness and avoid pressing the material too loosely or too tightly.

[0045] Bidirectional cutting: When the self-adhesive label 5 is conveyed to the area below cutter 1 324 and cutter 2 3217, the dual-axis motor 312 drives the slide bar 313 to drive the adjustment platform 321 to descend rapidly. Cutter 1 324 first performs a horizontal cut on the substrate (cutting the horizontal connection of the label layer); then, the cylinder 322 finely adjusts the position of the cross slide bar 323 and the T-shaped slide bar 3213 again, and cutter 2 3217 performs a vertical cut (cutting the vertical connection of the label layer). A single cut can complete the forming of a rectangular label. During the cutting process, the gear 3216 ensures the synchronization of the movement of cutter 1 and cutter 2 to avoid "cutting edge misalignment".

[0046] The cut self-adhesive labels 5 (including the backing paper and the formed label) continue to be pulled by the double rollers 417 to the subsequent receiving device (not shown). The backing paper and the label layer can be separated by the subsequent separation equipment. After a batch of labels is cut, the dual-axis motor 312, cylinder 322 and roller drive motor are turned off. The residual sticky substances on the surface of cutter 1 324 and cutter 2 3217 are cleaned (to avoid affecting the next cut). The elasticity of spring 413 is checked for decay and the gear 3216 is checked for wear to ensure that the equipment runs stably next time.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
