Description

Technical Field

[0001] This utility model relates to the field of label production technology, and in particular to a label quality testing device. Background Technology

[0002] Label quality inspection is a crucial step in ensuring that labels meet relevant standards and requirements during production, distribution, and use. It involves checking whether the text, patterns, and barcodes on the label are clear and legible, without blurring, ghosting, or broken lines, and whether the label surface is flat and free of defects such as wrinkles, bubbles, and scratches. Label quality inspection is an indispensable step in label production.

[0003] The existing utility model patent with publication application number CN218443736U discloses a label quality inspection device for a flat shearing machine, including an inspection table, guide rollers, a vision inspection component, a driven shaft, a drive shaft, a motor, a quick loading and unloading device, and an anti-reflective structure. This utility model simplifies the operation process by incorporating a quick loading and unloading device on the outer surface of the drive shaft. Users can unlock and lock the roll sleeve simply by pressing the sliding sleeve, reducing the time required to replace the roll sleeve and improving label inspection efficiency. Furthermore, the anti-reflective structure on the side of the vision inspection component allows for the activation of an LED light panel for illumination during use. The light emitted by the LED light panel is diffused through a soft light filter, reducing glare on labels made of high-gloss label paper. The LED light panel can also be freely adjusted in angle via a gooseneck fitting to provide a good lighting environment for the vision inspection component. However, traditional label quality inspection equipment requires the label roll to maintain appropriate tension during feeding in actual production and inspection scenarios to ensure that the labels can pass through the inspection area smoothly and continuously. However, due to design limitations, traditional equipment lacks a guide mechanism or adjustment mechanism specifically for dynamically adjusting the tightness of the label roll. When the label roll starts to be fed, due to the unevenness that may exist during the winding process, such as differences in winding force or uneven thickness of the material itself, the two sides of the label roll are prone to inconsistent tightness. This uneven tension on both sides directly leads to a difference in the rotation speed of the label roll during feeding. Specifically, the tighter side experiences greater friction and therefore feeds at a slower speed, while the looser side experiences less friction and feeds at a faster speed. This inconsistency in rotation speed gradually accumulates, causing the label roll to experience uneven tension during feeding. Over time, this uneven tension gradually increases, and when it exceeds the limit that the label material can withstand, it will cause the label roll to tear and break. The tearing and breaking of label rolls not only forces the ongoing testing work to be interrupted, but also requires operators to spend time reorganizing the label rolls, reloading, and adjusting the equipment. This undoubtedly increases downtime during the testing process and seriously affects testing efficiency. Moreover, frequent label roll breakage may also lead to waste of label materials and increase production costs. In addition, the reconnection or processing of broken labels may introduce new quality problems, further affecting the accuracy and reliability of label quality testing. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A label quality inspection device, comprising: The device body and the detection mechanism are located at the upper end of the device body and are used to detect the label printing quality. An adjustment mechanism is provided inside the main body of the device for adjusting tightness. The adjustment mechanism includes an inner wall plate, a magnetic block is inserted inside the inner wall plate, and a magnetic groove is formed inside the inner wall plate.

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention. Example

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A label quality inspection device, comprising: The device body 1 and the detection mechanism 2 are located at the upper end of the device body 1 and are used to detect the label printing quality. Adjustment mechanism 3 is located inside the main body 1 of the device and is used to adjust the tightness. Adjustment mechanism 3 includes inner wall plate 31, magnetic block 32 is inserted inside the inner wall plate 31, and magnetic groove 33 is opened inside the inner wall plate 31.

[0023] In this embodiment, a guide wheel 34 is inserted into one end of the magnetic block 32, a support block 35 is sleeved on one end of the guide wheel 34, a telescopic post 36 is provided on one end of the support block 35, an elastic element 37 is sleeved on the outer side of the telescopic post 36, the inner wall of the elastic element 37 cooperates with the outer surface of the telescopic post 36, several sets of guide wheels 34 are installed, the outer surface of the magnetic block 32 is in contact with the magnetic groove 33, a receiving plate 38 is connected to one end of the telescopic post 36, a sliding sleeve 309 is connected to one end of the receiving plate 38, and a sliding rod is inserted inside the sliding sleeve 309. 308, the inner wall of the sliding sleeve 309 slides in conjunction with the sliding rod 308. To further enhance the flexibility and adaptability of the adjustment mechanism 3, a telescopic column 36 is installed at one end of the support block 35. The telescopic column 36 is made of high-strength alloy steel, possessing good rigidity and toughness, and can withstand large tensile and compressive forces. Simultaneously, an elastic element 37 is sleeved on the outer side of the telescopic column 36. The elastic element 37 is made of high-quality spring steel and undergoes a special heat treatment process, possessing excellent elastic properties and fatigue life. When the operator pulls one end of the support block 35... When a handle made of frosted material is used, the special frosted texture on the handle surface provides good friction, making it easy for the operator to apply force. Under the action of pulling force, the telescopic column 36 elastically contracts, driving the guide wheel 34 to move to the right. At this time, the elastic element 37 is compressed and stores elastic potential energy. When the operator releases the handle, the elastic element 37 releases the stored elastic potential energy by its own elasticity, pushing the telescopic column 36 back to its original length, and then driving the magnetic block 32 at the other end of the guide wheel 34 to reset. Due to the magnetic attraction between the magnetic block 32 and the magnetic groove 33, the magnetic block 32 can be accurately and stably inserted into the magnetic grooves 33 at different heights inside the inner wall plate 31 to achieve magnetic connection. Through this flexible adjustment method, the operator can conveniently and quickly adjust the positional relationship between multiple sets of guide wheels 34 according to the actual tightness of the label roll, thereby accurately controlling the tightness of the label roll when feeding in the middle section. This effectively solves the problem of tearing and breakage caused by the different rotation speeds on both sides of the label roll in traditional equipment, and greatly improves the stability and reliability of label feeding. In addition, to ensure the stability and accuracy of the adjustment mechanism 3 during operation, a sliding sleeve 309 is installed at one end of the receiving plate 38. The sliding sleeve 309 is made of wear-resistant, self-lubricating engineering plastic and is precision machined internally to form a good sliding fit with the sliding rod 308. The sliding rod 308 is made of high-strength, high-precision metal material and is chrome-plated, possessing excellent wear resistance and corrosion resistance. The sliding sleeve 309 can slide freely up and down along the sliding rod 308. When the operator adjusts the position of multiple sets of guide wheels 34, the sliding sleeve 309 slides synchronously on the sliding rod 308, providing additional support and guidance for the adjustment mechanism 3, effectively reducing the shaking and deviation caused by the adjustment action, and ensuring the adjustment accuracy and stability of the guide wheel 34 position. In summary, through the above series of innovative designs and optimizations, the adjustment mechanism 3 has successfully achieved all-round support and guidance for label paper feeding and flexible tension adjustment. It not only significantly improves the working efficiency and detection accuracy of label quality testing equipment, but also greatly reduces the equipment failure rate and label loss rate, providing strong support for the quality control and cost control of label manufacturing enterprises. It has broad application prospects and promotion value in the field of label quality testing. In addition to the above design, one end of the guide wheel 34 rotates with the inside of the magnetic block 32, and the other end of the guide wheel 34 rotates with the inner wall of the support block 35. A handle is installed on one end of the support block 35, and the outer surface of the handle is made of frosted material. In the embodiments of this application, the testing mechanism 2 includes a feeding wheel 21, and a winding wheel 22 is inserted into the inner wall of the main body 1 of the device; Meanwhile, an inspection instrument 23 is installed inside the main body 1, and a receiving wheel 24 is installed at one end of the main body 1. In the field of label quality inspection, in order to achieve comprehensive, accurate, and efficient inspection of label products and meet increasingly stringent quality control requirements, we have carefully installed a fully functional and ingeniously designed inspection mechanism 2 at the upper end of the main body 1. The components of this inspection mechanism 2 work together to form a complete and smooth label inspection process, ensuring that every label that passes inspection meets high-quality standards.

[0024] The feeding stage, as the starting point of the entire inspection process, is crucial. The feeding roller 21, installed at a key position at one end of the inspection mechanism 2, is responsible for accurately and stably feeding the label rolls to be inspected into the inspection system. The feeding roller 21 employs a high-precision manufacturing process, and its surface undergoes special treatment, possessing excellent friction and wear resistance. This ensures that just the right amount of friction is maintained between the roller and the label roll during feeding, preventing damage to the labels due to excessive friction and avoiding feeding difficulties or slippage due to insufficient friction. Simultaneously, the feeding roller 21 is equipped with an advanced drive system that can precisely control the feeding speed and quantity. It flexibly adjusts feeding parameters according to different label materials, sizes, and inspection requirements, ensuring that the labels enter the subsequent inspection stages at a stable and uniform speed.

[0025] After the label roll is fed out from the feeding roller 21, it enters the flattening and guiding area composed of multiple sets of feeding rollers 22. These feeding rollers 22 are carefully laid out and designed to form multiple flattening and guiding defenses. Each set of feeding rollers 22 uses a special elastic material and a reasonable pressure adjustment mechanism, which can automatically adjust the pressure according to the thickness and material of the label to ensure that the label is flattened without being excessively squeezed or deformed. In terms of guidance, the spacing and angle between the feeding rollers 22 are precisely calculated to guide the label to move smoothly along the predetermined path, effectively avoiding problems such as wrinkles, deviations or tangles of the label during the feeding process, laying a solid foundation for subsequent accurate detection. After being flattened and guided, the labels enter the core part of the inspection mechanism 2—the inspection instrument 23. The inspection instrument 23 integrates various advanced inspection technologies and sensors, possessing high-precision, high-speed, and multi-functional inspection capabilities. It can comprehensively inspect multiple key quality indicators of the labels, including but not limited to printing quality such as the clarity of text and patterns, color accuracy, absence of missing prints, ghosting, and other defects; dimensional accuracy such as whether length, width, and thickness meet design requirements; surface quality such as the absence of scratches, stains, bubbles, and other flaws; and special functions such as the readability of barcodes and QR codes, and the effectiveness of anti-counterfeiting labels. During the inspection process, the inspection instrument 23, through high-speed scanning and real-time data analysis technology, can quickly and accurately capture any subtle defects or quality problems on the labels and present the inspection results in an intuitive and clear manner. Simultaneously, it transmits relevant data to the control system for recording and analysis, providing a strong basis for subsequent quality traceability and improvement. After the labels have completed inspection, they enter the receiving stage, where they are wound up by the receiving roller 24. The receiving roller 24 also uses high-quality materials and advanced manufacturing processes, possessing strong winding capabilities and stable operating performance. It can automatically adjust the winding speed according to the label feeding speed and inspection progress, ensuring that the labels are neatly and tightly wound on the receiving roller 24, avoiding problems such as looseness, wrinkles, or uneven winding. In addition, the receiving roller 24 is also equipped with a tension control system, which can monitor and adjust the tension in real time during the winding process, ensuring that the labels maintain appropriate tension at all times during the winding process, preventing the labels from deforming or breaking due to excessive tension, or resulting in loose winding due to insufficient tension. Through the coordinated operation of the aforementioned feeding roller 21, multiple sets of feeding rollers 22, detector 23, and take-up roller 24, the detection mechanism 2 achieves a complete automated process from label feeding, flattening and guiding, accurate detection to take-up, which greatly improves the efficiency, accuracy and reliability of label quality detection, provides label manufacturers with a powerful quality assurance means, and helps to improve the product quality and market competitiveness of enterprises.

[0026] The label quality inspection device provided by this utility model is used as follows: The label quality inspection device provides a detection mechanism 2 installed on the upper end of the main body 1. A feeding wheel 21 feeds the label at one end, multiple sets of feeding wheels 22 flatten and guide it, a detector 23 inspects the label, and a take-up wheel 24 takes the label back. An adjustment mechanism 3 is installed on the upper end of the main body 1, and an inner wall plate 31 is installed on the upper end of the main body 1. Multiple sets of magnetic blocks 32 are inserted into the inner wall plate 31, so that the magnetic blocks 32 are magnetically attracted in the magnetic grooves 33. A guide wheel 34 is inserted at one end of the magnetic block 32, rotating within the magnetic block 32. The other end of the guide wheel 34 rotates within the support block 35, allowing the multiple sets of guide wheels 34 to... During label roll feeding, the label roll is guided and flattened. A telescopic column 36 is installed at one end of the support block 35, and an elastic element 37 is sleeved on the outside of the telescopic column 36. When the frosted handle at one end of the support block 35 is pulled, the guide wheel 34 is pulled to the right. Due to the elasticity of the elastic element 37, after the handle is released, the magnetic block 32 at the other end of the guide wheel 34 is reset and inserted into the magnetic grooves 33 at different heights inside the inner wall plate 31 for magnetic connection. This allows adjustment of the position between multiple sets of guide wheels 34 to adjust the tightness of the label roll feeding at the middle section. A sliding sleeve 309 is installed at one end of the receiving plate 38, allowing the sliding sleeve 309 to slide up and down on the sliding rod 308 to support the position of multiple sets of guide wheels 34 during adjustment. This achieves the effect of supporting and guiding the label paper feeding and adjusting the tightness.
