Description

Technical Field

[0001] This utility model relates to an adjustable equipment positioning device. Background Technology

[0002] Laser-coated aluminized film can be used for paper-plastic lamination in high-end printed materials. After printing, it can be used to create high-end integrated laser-printed cigarette boxes, exhibiting a strong, bright, seven-color pattern effect under light, effectively enhancing the quality of the printed materials. This film is generally composed of a substrate layer such as PET or OPP and an aluminized layer. The substrate layer, such as PET, has a certain degree of hygroscopicity; it absorbs water and expands slightly when humidity increases, and loses water and shrinks when humidity decreases, leading to stretching or shrinkage deformation of the film. The aluminized layer, on the other hand, absorbs almost no water, has strong dimensional stability, and does not deform significantly with changes in humidity. This difference in characteristics means that humidity changes in different weather conditions can disrupt the dimensional balance between the substrate layer and the aluminized layer, causing stretching or shrinkage deformation of the film, resulting in problems such as warping and wrinkles. Therefore, the tension needs to be adjusted during processing to counteract the deformation. Existing laser-coated aluminized film processing equipment cannot adjust the tension according to the deformation of the laser-coated aluminized film under different environments, resulting in uneven cigarette boxes with wrinkles. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an adjustable equipment positioning device.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: An adjustable equipment positioning device includes a base frame, a tension adjusting device, a transmission roller, a support frame, a film, a first support rod, and a second support rod. The tension adjusting device, the support frame, and the first support rod are all mounted on the base frame. The tension adjusting device is correspondingly located on both sides of the base frame. The tension adjusting device includes a fixed seat and a screw. The fixed seat has a movable groove, and one side of the movable groove has a through hole. The two ends of the second support rod are respectively embedded in the movable grooves of the two fixed seats and can slide back and forth along the movable groove. The screws on both sides pass through the corresponding through holes and are threaded to the two ends of the second support rod. A gap is provided between the first support rod and the second support rod, and the film passes through the gap and is sleeved on the transmission roller.

[0005] Preferably, the second support rod is positioned above the first support rod.

[0006] Preferably, the device also includes a fastening nut, which is threadedly connected to the screw, and the threaded connection between the fastening nut and the screw is located outside the movable groove and close to the through hole.

[0007] Preferably, the support frame is provided with a number of mounting holes, and the transmission roller is detachably connected to the mounting holes.

[0008] Preferably, several mounting holes are distributed from top to bottom.

[0009] Preferably, the system also includes an elastic sleeve that is fitted over the first and second support rods.

[0010] Preferably, the elastic sleeve is located on both sides of the first support rod and the second support rod.

[0011] Preferably, the drive roller is located above the second support rod.

[0012] Adapting to environmental changes and effectively improving product quality: The core advantage of this invention lies in its ability to actively and precisely counteract the deformation of the laser-coated aluminum film caused by fluctuations in ambient humidity through a unique tension adjustment device. Specifically, by rotating a screw to drive the second support rod to move back and forth within the movable groove of the fixed base, the wrap angle and tension of the film between the first and second support rods can be changed. This adjustment mechanism can directly address the expansion or contraction of the substrate layer, such as PET, due to moisture absorption or loss, ensuring that the film maintains a suitable stretching state throughout the processing. This fundamentally reduces or even eliminates warping and wrinkles in finished cigarette packaging, significantly improving the product's flatness and aesthetics.

[0013] With its ingenious structure and flexible adjustment, this device boasts high practicality and economy: The entire structure is scientifically and rationally designed, with simplified components including a base frame, tension adjustment device, and support rods. This not only reduces manufacturing complexity and cost, facilitating mass production, but also simplifyes equipment maintenance and operation. The tension adjustment device uses screw drive, ensuring smooth and precise adjustment. Furthermore, multiple mounting holes on the support frame allow for flexible adjustment of the transmission roller height according to actual production needs. This multi-position adjustable design enhances adaptability to different film specifications or process routes, ensuring smooth film transmission and uniform tension, further guaranteeing processing quality.

[0014] Easy to operate and highly stable, this device helps improve production efficiency: Its operation is meticulously designed and intuitive. When adjusting tension, simply rotating the screw drives the second support rod to move smoothly within the movable groove of the fixed seat, thus precisely adjusting the film tension. After adjustment, the screw can be easily locked using the fastening nut. This locking mechanism effectively prevents accidental displacement of the second support rod due to equipment vibration during continuous production, ensuring long-term stability of the tension setting and significantly reducing the frequency of mid-production shutdowns for adjustment due to tension failure, thus guaranteeing production continuity.

[0015] In addition, the optional elastic sleeve can be fitted onto the first and second support rods, which not only enhances the stability of the second support rod position, but also effectively buffers and reduces the vibration transmission between the first and second support rods during operation. This design further improves the smoothness of the film during transmission and helps maintain the uniformity of tension.

[0016] The stable operation of the equipment, combined with its convenient adjustment methods, ensures that the entire production process can proceed smoothly and efficiently, minimizing unplanned downtime and thus improving overall production efficiency and product yield. Attached Figure Description

[0017] Figure 1 This is a three-dimensional structural diagram of the present invention; Figure 2 This is a schematic diagram of the tension adjustment device. Detailed Implementation

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings: like Figure 1 , Figure 2 As shown, an adjustable equipment positioning device includes a base frame 1, a tension adjusting device, a transmission roller 2, a support frame 3, a film 4, a first support rod 5, and a second support rod 6. The tension adjusting device, the support frame 3, and the first support rod 5 are all mounted on the base frame 1. The tension adjusting device is correspondingly located on both sides of the base frame 1. The tension adjusting device includes a fixed seat 71 and a screw 72. The fixed seat 71 has a movable groove 73, and one side of the movable groove 73 has a through hole 74. The two ends of the second support rod 6 are respectively embedded in the movable groove 73 of the fixed seats 71 on both sides, and can slide back and forth along the movable groove 73. The screws 72 on both sides pass through the corresponding through holes 74 and are threaded to the two ends of the second support rod 6. A gap 51 is provided between the first support rod 5 and the second support rod 6. The film 4 passes through the gap 51 and is sleeved on the transmission roller 2.

[0019] like Figure 1 , Figure 2 As shown, the second support rod 6 is located above the first support rod 5.

[0020] like Figure 1 , Figure 2 As shown, it also includes a fastening nut 9, which is threadedly connected to the screw 72. The threaded connection between the fastening nut 9 and the screw 72 is located outside the movable groove 73 and is close to the through hole 74.

[0021] like Figure 1 , Figure 2As shown, the support frame 3 has several mounting holes 31, and the transmission roller 2 is detachably connected to the mounting holes 31. The mounting holes 31 are distributed from top to bottom.

[0022] like Figure 1 , Figure 2 As shown, it also includes an elastic sleeve 8, which is fitted onto the first support rod 5 and the second support rod 6. The elastic sleeve is located on both sides of the first support rod 5 and the second support rod 6. The transmission roller 2 is located above the second support rod 6.

[0023] Working principle: like Figure 1 , Figure 2 As shown, the tension adjustment device is located on both sides of the base frame 1. After the screw 72 is inserted into the through hole 74, it is threadedly connected to the second support rod 6. The position of the transmission roller 2 can be adjusted by selecting different mounting holes. When it is necessary to adjust the position of the second support rod 6, simply rotate the screw 72 to disengage it from the second support rod 6. At this time, the second support rod 6 slides back and forth in the movable groove 73 until it is adjusted to the desired position. Then, rotate the screw in the opposite direction to make the screw threadedly connected to the second support rod 6. Then, rotate the fastening nut 9 to further fix the second support rod 6. Two elastic sleeves are placed on the first support rod 5 and the second support rod 6. The elastic sleeves are located on both sides of the base frame 1 to adjust the position of the second support rod 6, thereby changing the wrap angle and tension of the film between the first support rod and the second support rod.

[0024] Base frame: As the fundamental support structure of the entire device, it provides a stable mounting platform for other components such as the tension adjustment device, support frame, and first support rod, ensuring that all components can work together without displacement or shaking during operation, thus maintaining the overall stability of the device. Its material is typically high-strength metal, such as aluminum alloy or steel, to ensure structural integrity under various external forces. Tension Adjustment Device: This is one of the core components of the entire equipment. It mainly consists of a fixed base and a screw. The fixed base has a carefully designed movable groove, with a through hole cleverly connected to one side of the groove. The two ends of the second support rod are embedded in the movable grooves of the two fixed bases and can slide freely back and forth along the groove. The screw passes through the corresponding through hole and is tightly threaded to the two ends of the second support rod. By rotating the screw, the position of the second support rod in the movable groove is adjusted, thereby controlling the film tension. This unique design allows the tension adjustment device to respond quickly and accurately to changes in various production needs, ensuring that the film is always in an optimal tension state during processing. Drive rollers: These are crucial guides for the film during processing, ensuring its smooth movement along a predetermined path. The drive rollers are detachably connected to mounting holes on the support frame, allowing their height to be flexibly adjusted to meet diverse production needs. For example, when processing films of different thicknesses or materials, adjusting the height of the drive rollers optimizes film transmission, preventing issues such as film misalignment and wrinkles, and ensuring the stability and continuity of film processing. Support Frame: The support frame acts as a robust skeleton for the device, providing reliable support for the drive rollers. Several mounting holes are arranged in an orderly fashion from top to bottom, allowing the drive rollers to be easily and flexibly adjusted in height according to different production process requirements. This design greatly enhances the device's adaptability to films of different specifications and various complex process routes, ensuring the smoothness and uniformity of film tension during transmission, thus laying a solid foundation for improving product quality. Thin film: As the object of processing, the thin film passes through the gap between the first and second support rods and is then fitted onto the drive roller. Throughout the processing, the state of the thin film directly affects the quality of the final product. This device, through the regulation of each component, can effectively ensure that the thin film maintains a suitable tension state during processing, avoiding deformation caused by uneven tension or environmental factors, thereby producing high-quality products. The first and second support rods work together, maintaining close contact with the film. By adjusting the wrap angle and tension of the film between them, they respond to the expansion or contraction of the substrate layer caused by environmental changes. The first support rod, located below, provides a stable support base for the film; the second support rod, located above, can be flexibly adjusted in conjunction with the screw, thereby controlling the film tension. Their close cooperation during production ensures the film is always in optimal processing condition.

[0025] Through long-term application in actual production and statistical data analysis, the device has demonstrated a significant improvement in product quality. Before using the device, due to the difficulty in controlling film tension, the proportion of warping and wrinkling in cigarette box packaging was relatively high, averaging around 15%. This not only affected the product's appearance but also led to a certain scrap rate and increased production costs. However, after adopting the adjustable positioning device, the situation was greatly improved. Through tension adjustment and stable film transmission, warping and wrinkling of cigarette box packaging were effectively suppressed. Statistics show that the proportion of warping and wrinkling in cigarette box packaging has been significantly reduced to below 3%. For example, in a one-month production cycle, a total of 100,000 cigarette boxes were produced. Before using the device, 15,000 cigarette boxes had warping and wrinkling problems; after using the device, the number of problematic cigarette boxes decreased to less than 3,000. The flatness and aesthetics of the products have been significantly improved, gaining high customer recognition and winning the company a larger market share.

[0026] In a large cigarette box packaging manufacturing enterprise, this adjustable positioning device has been widely used. Inside the production workshop, multiple machines operate in an orderly manner, completing a large number of cigarette boxes of different specifications every day. During the production process, the humidity and temperature of the workshop environment fluctuate with seasonal and diurnal variations. For example, during the summer rainy season, air humidity increases significantly, causing the film substrate layer (such as PET) to easily absorb moisture and expand; while in winter, the climate is dry, and the film easily loses water and shrinks. Faced with these complex and changing environmental conditions, the adjustable positioning device demonstrates strong adaptability. Operators can easily adjust the position of the second support rod by rotating the screw according to environmental changes and the actual state of the film, quickly changing the wrap angle and tension of the film to ensure that the film remains stable throughout the processing. Simultaneously, different specifications of film are required according to the design requirements of different cigarette box packaging. Operators can flexibly adjust the height of the transmission roller using the mounting holes on the support frame, enabling the equipment to smoothly process various films. Whether it is a thin, high-grade cigarette box film or a thicker, ordinary cigarette box film, the device can handle it with ease, ensuring smooth production.

[0027] The device's convenient operation and stable performance have made a significant contribution to improving production efficiency. In terms of operation, adjusting film tension requires only a simple rotation of the screw for quick and precise adjustment; the entire process is simple and requires no complex techniques or significant time investment. After adjustment, the screw is tightened using the locking nut, another quick and easy operation. This convenient operation significantly reduces downtime caused by equipment adjustments. Regarding stable operation, the device effectively suppresses the impact of equipment vibration on the position of the second support rod through the synergistic effect of components such as the elastic sleeve, ensuring the long-term stability of the tension setting. During continuous production, the frequency of mid-production shutdowns due to tension failure has been greatly reduced. Statistics show that before using this device, downtime due to equipment adjustments and malfunctions averaged about 2 hours per day, severely impacting production progress. After using the device, downtime has been significantly reduced, averaging less than 0.5 hours per day. Production efficiency has been greatly improved, increasing by approximately 20% compared to before. Based on an 8-hour workday for a production line, before using this device, the actual daily production time was 6 hours, producing 5,000 cigarette boxes. After using the device, the actual daily production time increased to 7.5 hours, and the number of cigarette boxes produced increased to over 6,000. This not only improved the company's production capacity but also reduced the unit production cost, enhancing the company's market competitiveness.
