Technical Field
[0001] This utility model relates to the technical field of nail sticker production equipment, specifically an adjustable guide device for a circular knife device for precise cutting of nail stickers. Background Technology
[0002] In the beauty and nail industry, nail stickers have gained widespread popularity due to their ease of use, diverse styles, and ability to quickly meet users' personalized nail art needs. Market demand continues to rise. To achieve efficient mass production of nail stickers, precise cutting of the substrate is a crucial step in the processing, directly affecting the final product quality and user experience.
[0003] Currently, the industry commonly uses circular blade cutting devices to cut substrates during transport. This processing method, thanks to the continuous rotation of the circular blade, can match the conveying speed of the substrate, thereby achieving efficient continuous cutting and has significant advantages in large-scale production.
[0004] However, in actual production, the above processing method has certain technical defects. Specifically, when the substrate is continuously conveyed under the drive of the conveying mechanism, due to the combined effects of various factors such as the material properties of the substrate itself (such as having a certain degree of flexibility and stretchability), the mechanical vibration of the conveying mechanism, uneven conveying tension, and the precision deviation of the guide components, the positional deviation along or perpendicular to the conveying direction is very likely to occur.
[0005] When the substrate shifts position, its relative position to the fixed-position circular blade will deviate, resulting in inaccurate cutting position. This not only causes the shape and size of the nail stickers to not meet the design requirements, leading to an increased scrap rate, but also affects the normal progress of subsequent processing steps (such as lamination, slitting, etc.), reducing overall production efficiency and increasing production costs. Utility Model Content
[0006] Based on this, the purpose of this utility model is to provide an adjustable guide device for a circular knife device for precise cutting of nail stickers, so as to solve the technical problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable guide device for a circular knife device for precise cutting of nail stickers, including a guide mechanism, wherein the guide mechanism includes a bearing roller, an axial guide slide cylinder is axially slidably connected to the outer side of the bearing roller, and a rubber ring is fixed to the outer side of the axial guide slide cylinder; The bearing roller is provided with a groove that cooperates with the axial guide slide. An electric push rod is installed on one side inside the bearing roller, and the output end of the electric push rod is connected to the axial guide slide. The electric push rod can drive the axial guide slide to move along the groove to adjust the axial position of the substrate. The axial guide slide is fixed with retaining rings on both sides, and the retaining rings serve to limit the axial movement of the rubber ring. Below the bearing roller, at the bottom of the substrate, a matching roller is provided. The rubber ring cooperates with the matching roller to squeeze and convey the substrate, and through friction, the substrate moves synchronously axially with the axial guide slide. A gas slip ring mechanism is provided on one side of the guide mechanism. The gas slip ring mechanism includes a fixed outer ring and a rotating inner ring. The fixed outer ring is fixedly connected to the external frame through two sets of mounting plates, and threaded holes are opened on the inner side of the two sets of mounting plates. The inner rotating ring is equipped with a pipe that cooperates with the electric push rod, and the outer fixed ring is connected to a gas connection pipe. The gas connection pipe, the outer fixed ring and the inner rotating ring cooperate to supply gas to the electric push rod in the rotating state to maintain its operation. The bearing roller is connected to the electric push rod, and the electric push rod is connected to the rotating inner ring through a connecting mechanism. The connecting mechanism includes a first connecting cylinder, a second connecting cylinder, and a third connecting cylinder, and the connecting mechanism can realize the synchronous rotation transmission of the bearing roller, the electric push rod, and the rotating inner ring; The first connecting cylinder, the second connecting cylinder, and the third connecting cylinder are connected by multiple sets of fastening bolts, and the second connecting cylinder and the third connecting cylinder are connected by multiple sets of fastening bolts. A circular blade cutting mechanism is provided on one side of the guiding mechanism. The circular blade cutting mechanism plays a role in the precise cutting of the substrate. Limiting mechanisms are provided at both ends of the guiding mechanism and the circular blade cutting mechanism. Each limiting mechanism includes two sets of limiting rollers, which play a role in the adhesion and limiting of the substrate.
[0008] In summary, the present invention has the following main advantages: This invention uses an electric push rod to drive an axial guide cylinder to move along a slide groove. The friction between the rubber ring and the substrate adjusts the substrate's axial position, ensuring precise alignment between the substrate and the circular cutter mechanism. This significantly improves cutting accuracy and reduces scrap rates. The connecting mechanism enables synchronous rotation of the carrying roller, electric push rod, and rotating inner ring. Simultaneously, the gas slip ring mechanism, through the cooperation of the fixed outer ring, rotating inner ring, and gas connecting pipe, continuously supplies air to the rotating electric push rod, meeting the dual requirements of power transmission and pneumatic control during dynamic operation. This ensures stable operation of the electric push rod. Precise guidance adjustment reduces rework and process delays caused by cutting deviations. Furthermore, the limiting mechanism further assists in ensuring conveying stability by limiting the substrate's adhesion, contributing to improved continuity and efficiency in nail sticker production and reduced production costs.

[0011] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0012] The embodiments of this utility model will be described below based on its overall structure.
[0013] Example 1 An adjustable guide device for a circular blade device used for precise cutting of nail stickers, such as... Figure 1-6 As shown, it includes a guiding mechanism 1, a gas slip ring mechanism 5, a connecting mechanism 6, and a circular knife cutting mechanism 2. The guiding mechanism 1 is installed at the front end of the circular knife cutting mechanism 2, and both ends of the two are provided with limiting mechanisms 3. Each set of limiting mechanisms 3 includes two sets of limiting rollers, which are used to form a bonding limit on the substrate 4.
[0014] Guide mechanism 1 includes a bearing roller 101, an axial guide cylinder 102 is axially slidably connected to the outer side of the bearing roller 101, and retaining rings 107 are fixed on both sides of the axial guide cylinder 102. A rubber ring 104 is snapped between the retaining rings 107. A groove 103 adapted to the axial guide cylinder 102 is opened on the surface of the bearing roller 101. An electric push rod 105 is embedded in one side of the bearing roller 101, and its output end is fixed to the end of the axial guide cylinder 102 by bolts. A mating roller 106 is provided below the bearing roller 101 corresponding to the position of the rubber ring 104. A gap is formed between the rubber ring 104 and the mating roller 106 for the substrate 4 to pass through, and the two form a compression fit on the substrate 4.
[0015] Gas slip ring mechanism 5: includes a fixed outer ring 501 and a rotating inner ring 502. The fixed outer ring 501 is bolted to the external frame through two sets of mounting plates 7. The mounting plates 7 have threaded holes on their inner sides for adjusting the fixed position. The rotating inner ring 502 is nested inside the fixed outer ring 501 to form a sealed gas passage. A pipe that communicates with the electric push rod 105 passes through its interior axially. A gas connecting pipe 503 is connected to one side of the fixed outer ring 501.
[0016] Connection mechanism 6 includes a first connecting cylinder 601, a second connecting cylinder 602, and a third connecting cylinder 603 that are sequentially sleeved together. The first connecting cylinder 601 is keyed to the end of the bearing roller 101. The two ends of the second connecting cylinder 602 are respectively fixed to the first connecting cylinder 601 and the outer shell of the electric push rod 105 by fastening bolts 604. One end of the third connecting cylinder 603 is fixed to the end of the output shaft of the electric push rod 105, and the other end is keyed to the rotating inner ring 502.
[0017] Working process: After the substrate 4 is initially limited by the limiting mechanism 3, it enters the guiding mechanism 1. The rubber ring 104 and the mating roller 106 squeeze the substrate 4 and rotate with the carrying roller 101 to achieve conveying. When the displacement sensor detects the axial displacement of the substrate 4, the electric push rod 105 drives the axial guide slide 102 to slide along the slide groove 103. The friction between the rubber ring 104 and the substrate 4 drives the substrate 4 to reset. At the same time, the carrying roller 101 drives the electric push rod 105 and the rotating inner ring 502 to rotate synchronously through the connecting mechanism 6. The external air source continuously supplies air to the electric push rod 105 through the gas connecting pipe 503, the fixed outer ring 501, and the rotating inner ring 502 to ensure stable operation in the rotating state. After the substrate 4 is guided and adjusted, it enters the circular knife cutting mechanism 2 to complete the precise cutting.
[0018] Example 2 The difference between this embodiment and Embodiment 1 is that: the outer surface of the rubber ring 104 is uniformly distributed with diamond-shaped anti-slip patterns, which can increase the coefficient of friction with the substrate 4 to 0.6-0.8, making it suitable for smooth film substrates; the inner side of the slide groove 103 is fitted with a polytetrafluoroethylene wear-resistant strip, which reduces the sliding resistance of the axial guide slide cylinder 102 by 30% and increases the response speed to within 0.5s.
[0019] Its working principle is the same as that of Example 1. By optimizing the friction performance of the rubber ring 104 and the smoothness of the groove 103, the guiding adjustment accuracy and response efficiency of the substrate 4 are further improved.
[0020] The working principle of this utility model is as follows: When in use, the guide mechanism 1 is as follows: Figure 1 As shown, the guide mechanism 1 is installed on the front end of the circular knife cutting mechanism 2 on the nail sticker production line. The axial position of the substrate 4 is adjusted by the guide mechanism 1, so that the substrate 4 is better aligned with the circular knife cutting mechanism 2, thereby improving the overall cutting accuracy. Specifically, the outer side of the bearing roller 101 of the guide mechanism 1 is axially slidably connected to the axial guide slide 102, and the outer side of the axial guide slide 102 is fixed with a rubber ring 104. Thus, under the action of the outer side of the rubber ring 104 and the cooperating roller 106, the substrate 4 can be conveyed synchronously. When the substrate 4 experiences axial displacement on the rubber ring 104, the displacement sensor detects and activates the electric push rod 105. The output of the electric push rod 105 then drives the axial guide slide 102 to move back and forth along the slide groove 103. Simultaneously, due to the squeezing and conveying action of the rubber ring 104 and the mating roller 106 on the substrate 4, and the friction between the rubber ring 104 and the substrate 4, the axial guide slide 102 can drive the substrate 4 to perform axial adjustment through the rubber ring 104, thereby completing the reference guiding function of the substrate 4. Furthermore, since the bearing roller 101 needs to drive the electric push rod 105 to rotate, the bearing roller 101 and the electric push rod 105 are driven to rotate through the cooperation of the first connecting cylinder 601 and the second connecting cylinder 602. The rotation of the electric push rod 105 will drive the rotating inner ring 502 to rotate through the action of the second connecting cylinder 602 and the third connecting cylinder 603. The rotating inner ring 502 is provided with a pipe that cooperates with the electric push rod 105. The fixed outer ring 501 is fixedly connected to the external frame through two sets of mounting plates 7. The external air source enters the fixed outer ring 501 and the rotating inner ring 502 through the gas connecting pipe 503 and enters the electric push rod 105, thereby enabling the rotating electric push rod 105 to run. In other words, through the cooperation of the first connecting cylinder 601, the second connecting cylinder 602, and the third connecting cylinder 603, the mechanical transmission that drives the electric push rod 105 and the rotating inner ring 502 to rotate synchronously is realized; Meanwhile, by using the fixed outer ring 501 to connect with the external frame, and combined with the gas connection pipe 503, an air passage is established, so that the external air source can enter the electric push rod 105 through the fixed outer ring 501 and the rotating inner ring 502 in sequence.
[0021] In terms of performance, this structure ensures that the electric push rod 105 rotates synchronously with the bearing roller 101, and also achieves normal air supply while the electric push rod 105 is rotating, thus ensuring its stable operation and meeting the dual requirements of power transmission and pneumatic control of the equipment during dynamic operation.
