Description

Technical Field

[0001] This utility model belongs to the field of mechanical molding machine technology, and specifically relates to an adjustment mechanism for marking lines on nickel plates. Background Technology

[0002] In the field of modern packaging machinery molding machines, nickel plate bonding is a crucial step in ensuring the quality of the final product. However, traditional technologies face numerous challenges in this area, primarily focusing on the accuracy and efficiency of plate seam alignment. Specifically, when bonding nickel plates along the circumference of the printing roller, the precise alignment of the plate seams directly affects the quality of the finished product. Traditional manual adjustment methods rely on the experience and skill level of the operators, which not only leads to problems such as plate seam misalignment, overlapping edges, or uneven printing during production, but also results in a high scrap rate. Furthermore, due to the lack of consistency in this method reliant on individual skills, the quality of products from different batches often fluctuates, making it difficult to meet the stringent quality consistency requirements of the high-end market.

[0003] Furthermore, even existing molding machines that partially employ mechanical adjustment devices are structurally complex and expensive. This not only increases the cost of equipment procurement and maintenance, but more importantly, while these mechanical adjustment mechanisms improve adjustment accuracy to some extent, they cannot provide sufficient precision guarantees in applications requiring extremely high precision, such as high-end printing or processing of special materials, leading to products that do not meet expected standards. Additionally, the ambiguity of the adjustment benchmark in existing technologies is a significant problem. Due to the lack of a unified and clear adjustment benchmark, the entire adjustment process is highly susceptible to human factors, thus affecting the quality of the final product. This uncertainty also prolongs the time required for each adjustment, reducing overall production efficiency. Especially in mass production, every minor adjustment can consume a significant amount of time, accumulating and having a major impact on production plans. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide an adjustment mechanism for nickel plate mounting and marking. By employing a simpler and more efficient mechanical design, it solves the technical problems currently existing in the market, aiming to achieve precise alignment between the nickel plate seam and the printing roller, thereby significantly improving product quality and production efficiency. To solve the above problems, the technical solution adopted by this utility model is as follows: An adjustment mechanism for nickel plate mounting and marking, comprising: an angle iron assembly, a high-precision lead screw assembly, and a slide rail assembly. The high-precision lead screw is installed at both ends of the angle iron assembly via the slide rail assembly. The angle iron assembly includes a positioning reference angle iron and a marking moving angle iron. The positioning reference angle iron is fixed to the reference guide rod of the molding machine. The marking moving angle iron is connected to the positioning reference angle iron via the high-precision lead screw.

An adjustment device is provided at the end of the high-precision lead screw, allowing the user to adjust the lead screw via the adjustment device to drive the marking moving angle iron closer to or further away from the printing roller to adjust the gap.

[0005] Compared to existing technologies, the advantages of this invention are as follows: By providing a positioning reference angle iron, this application effectively avoids errors caused by human operation, improving the consistency and accuracy of plate seam alignment. Simultaneously, a high-precision lead screw is set between the positioning reference angle iron and the scribing moving angle iron for fine-tuning, ensuring precise alignment of the nickel plate seam with the edge of the printing roller, greatly improving product quality and production efficiency. Furthermore, the connection between the high-precision lead screw assembly and the positioning reference angle iron, along with the installation of slide rail assemblies at both ends of the positioning reference angle iron and the scribing moving angle iron to ensure the straightness of the high-precision lead screw movement, improves the stability and accuracy of the mechanism during adjustment, prevents tilting or jamming, and enhances the overall ease of operation and reliability of the equipment. More importantly, an adjustment button is configured at the end of the lead screw, allowing users to quickly adjust the gap by rotating the handwheel.

Detailed Implementation

[0018] The embodiments of this utility model are described in detail below, with reference to Figures 1 to 2This utility model provides an adjustment mechanism for marking lines on nickel plates, including: an angle iron assembly 100, a high-precision lead screw assembly 200, and a slide rail assembly 300. The high-precision lead screw assembly 200 is installed at both ends of the angle iron assembly 100 via the slide rail assembly 300. The angle iron assembly 100 includes a positioning reference angle iron 110 and a marking moving angle iron 120. The positioning reference angle iron 110 is fixed to the reference light rod of the molding machine. The marking moving angle iron 120 is connected to the positioning reference angle iron 110 via the high-precision lead screw assembly 200. The marking moving angle iron 120 can move back and forth along the direction of the high-precision lead screw assembly 200. An adjustment device 500 is provided at the end of the high-precision lead screw assembly 200. The user can adjust the high-precision lead screw assembly 200 via the adjustment device 500 to drive the marking moving angle iron 120 closer to or further away from the printing roller to adjust the gap. This application provides a positioning reference angle iron 110, effectively avoiding errors caused by human operation and improving the consistency and accuracy of plate seam alignment. Simultaneously, a high-precision lead screw is installed between the positioning reference angle iron 110 and the scribing moving angle iron 120 for fine-tuning, ensuring precise alignment of the nickel plate seam with the edge of the printing roller, greatly improving product quality and production efficiency. Furthermore, the connection between the high-precision lead screw assembly 200 and the positioning reference angle iron 110, and the installation of slide rail assemblies 300 at both ends of the positioning reference angle iron 110 and the scribing moving angle iron 120, ensures the straightness of the movement of the high-precision lead screw assembly 200, improving the stability and accuracy of the mechanism during adjustment, preventing tilting or jamming, and enhancing the overall ease of operation and reliability of the equipment. More importantly, an adjustment button is provided at the end of the lead screw, allowing users to quickly adjust the gap by rotating a handwheel. This not only significantly shortens adjustment time and improves work efficiency but also reduces labor costs and workload.

[0019] Furthermore, the slide rail assembly 300 includes multiple first fixed rails 310 and multiple first slide rails 320. The first fixed rails 310 are fixed to both ends of the positioning reference angle iron 110, and the first slide rails 320 are fixed to both ends and the center of the marking moving angle iron 120. The first fixed rails 310 serve as the fixed part for sliding guidance, while the first slide rails 320 serve as the movable part. The two form a sliding fit to ensure that the marking moving angle iron 120 can move smoothly along the set direction under the drive of the lead screw, avoiding tilting, jamming, and other phenomena. Especially under high-speed or frequent adjustment conditions, the multi-point slide rail design can effectively reduce vibration and friction, and improve the smoothness and reliability of operation. Of course, this application does not limit the fixing method of the first fixed rails 310 and the first slide rails 320 to the angle iron assembly 100. Preferably, both the first fixed rails 310 and the first slide rails 320 are provided with bases, and each base is provided with bolt holes, which are used to fix them to the angle iron assembly 100 by screwing. Furthermore, the high-precision lead screw assembly 200 proposed in this application includes a plurality of movable lead screws 210 and adjusting lead screws 220. One end of the movable lead screw 210 is fixed to a first fixed rail 310, and the first slide rail 320 has a first through hole 321, as shown in the reference. Figure 2 The other end of the movable lead screw 210 can pass through the first through hole 321 and connect to the scribing movable angle iron 120. The movable lead screw 210 is mainly used to provide stable support and guidance, ensuring the rigid connection and structural stability of the scribing movable angle iron 120 during movement; while the adjusting lead screw 220 is responsible for performing specific adjustment tasks, driving the scribing movable angle iron 120 to move back and forth by rotation, thereby achieving fine adjustment of the nickel plate contact position. Through the guiding effect of the first through hole 321, the movable lead screw 210 maintains a high alignment when it enters the scribing movable angle iron 120, thereby ensuring the straightness and stability of its movement trajectory. At the same time, this structure allows the scribing movable angle iron 120 to slide freely under the action of the lead screw without affecting its own structural integrity. The existence of the first through hole 321 also plays a dual role of limiting and guiding, preventing the scribing movable angle iron 120 from deflecting or tilting during movement, thereby improving the overall mechanism's movement accuracy and repeatability. Especially in high-frequency adjustment operations, this structure effectively reduces error accumulation and ensures that each adjustment achieves the expected results. Furthermore, the central axis of the movable lead screw 210, fixed to the positioning reference angle iron 110, is collinear with the center line of the first through hole 321. This design ensures that the scribing movable angle iron 120 always moves along a straight path during its movement, avoiding eccentric forces or lateral stresses caused by misalignment between the lead screw and the slide rail. When the central axis of the movable lead screw 210 is completely collinear with the center line of the first through hole 321, the driving force transmitted by the lead screw can directly act on the geometric center of the scribing movable angle iron 120, thereby achieving the most efficient force transmission and the least frictional loss.

[0020] Furthermore, referring to Figure 1 A lead screw seat 400 is centrally located on the positioning reference angle iron 110. The lead screw seat 400 has a second through hole 410. The adjusting lead screw 220 can pass through the first through hole 321 and the second through hole 410 sequentially. The central axis of the second through hole 410 is collinear with the center line of the first through hole 321. By strictly aligning the movement path of the adjusting lead screw 220 with multiple through holes, swaying and jitter during adjustment can be effectively eliminated, making the displacement of the scribing moving angle iron 120 more uniform and controllable. This is crucial for achieving high-precision nickel plate scribing, especially in applications where plate seam alignment is extremely critical. It avoids adjustment inaccuracies caused by bending or misalignment. The introduction of the lead screw seat 400 not only enhances the support strength of the adjusting lead screw 220 but also provides it with additional guiding functionality, thereby improving the stability and accuracy of the entire adjustment system. Furthermore, one end of the adjusting screw 220 is equipped with an adjusting device 500, which is a rotatable handwheel. Rotating the handwheel drives the adjusting screw 220 to rotate, causing the scribing moving angle iron 120 to move closer to or further away from the printing roller. As a common manual adjusting tool, the handwheel offers advantages such as ease of operation and intuitive feedback. Users can directly control the rotation of the screw by rotating the handwheel, thereby changing the position of the scribing moving angle iron 120 and achieving precise control of the nickel plate bonding gap. This method eliminates the need for a complex electrical control system, reducing equipment complexity and failure rate, making it ideal for the on-site operation needs of small and medium-sized enterprises. The adjustment device 500 proposed in this application fixes the positioning reference angle iron 110 to the reference light rod in front of the machine with bolts, ensuring that it is parallel to the axis of the printing roller. The nickel plate is manually initially attached to the printing roller, with the edge of the plate seam close to the positioning reference angle iron 110. The handwheel is turned to drive the scribing moving angle iron 120 to move towards the printing roller until the scribing moving angle iron 120 contacts the edge of the nickel plate seam. The alignment of the plate seam with the printing roller is observed, and the adjusting screw 220 is finely adjusted until complete alignment, completing the plate mounting and positioning. Furthermore, the horizontal plane of the positioning reference angle iron 110 is flush with the horizontal plane of the scribing moving angle iron 120, and the vertical plane of the positioning reference angle iron 110 is parallel to the vertical plane of the scribing moving angle iron 120. This design ensures that the relative positional relationship between the positioning reference angle iron 110 and the scribing moving angle iron 120 in space remains consistent, thus providing a unified geometric reference for the entire adjustment mechanism. Horizontal alignment means that the scribing moving angle iron 120 is always at the same height as the positioning reference angle iron 110 during the movement, avoiding scribing deviation caused by height difference; vertical parallelism ensures that the two are aligned in the vertical direction, making the scribing action more stable and reliable.

[0021] Furthermore, this application does not limit the pitch of the high-precision lead screw assembly 200. Preferably, the pitch of the high-precision lead screw assembly 200 is 0.05 mm. The pitch of the lead screw determines the distance it can push with each rotation; the smaller the pitch, the higher the adjustment accuracy. Using an ultra-fine pitch of 0.05 mm allows for extremely small displacement of the angle iron 120 when the user rotates the adjustment handwheel, thus enabling extremely precise adjustment. For example, if each rotation of the handwheel has 100 divisions, each division corresponds to a displacement of only 0.0005 mm. Furthermore, this application does not limit the specific material of the angle iron assembly 100. Preferably, the angle iron assembly 100 is made of aluminum alloy. Aluminum alloy has low density and high strength, which can meet the requirements of high-strength support while reducing the overall weight of the equipment, thus reducing transportation and installation costs. In addition, after anodizing, the aluminum alloy surface has good wear resistance and corrosion resistance, allowing it to maintain a long service life even in humid or dusty working environments.
