Description

Technical Field

[0001] This utility model relates to the field of printing tools technology, and in particular to a hot stamping equipment for canvas processing. Background Technology

[0002] In the field of canvas processing, hot stamping is a key step in enhancing the aesthetics and added value of canvas products. However, the hot stamping equipment currently available on the market still has many technical pain points in practical applications, making it difficult to meet the demand for efficient and high-quality processing. First, in the canvas conveying and pre-processing stage, existing equipment generally lacks an effective flattening and cleaning mechanism. Traditional equipment mostly relies on a single conveying roller for canvas transport, which cannot flatten the canvas in both directions. This causes uneven tension during the conveying process, resulting in wrinkles. Wrinkles directly affect the integrity and accuracy of the hot stamping pattern, causing a large number of defective products. At the same time, during storage and transportation, the canvas surface is prone to adhering to impurities such as lint and dust. Existing equipment does not have a specific cleaning structure. Impurities remaining on the canvas surface can cause problems such as pattern breaks and color differences during hot stamping, seriously reducing the quality of the hot stamping product. Second, in terms of component positioning and stability, the existing equipment's rotating roller positioning structure is complex and unreliable. Most equipment lacks a convenient limit adjustment method after the rotating roller is installed. During long-term canvas conveying, the rotating roller is prone to displacement due to canvas tension, causing the canvas conveying path to deviate from the preset trajectory. This not only further aggravates the wrinkling problem but may also cause equipment jamming. Therefore, the above problems need to be solved. Utility Model Content

[0007] Preferably, a guide rod is fixedly connected between the upper ends of the two limiting platforms, and a movable platform is threadedly connected to the lead screw. A guide hole for the guide rod is opened at the rear end of the movable platform, and the guide rod passes through the guide hole. An installation platform is installed on the other side of the movable platform, and multiple equidistant flexible brushes are installed on the bottom surface of the installation platform. An auxiliary groove is opened in the middle of the bottom surface of the movable platform. The auxiliary groove is a cuboid structure, and a second rotating roller is rotatably connected to the inner side of the auxiliary groove.

[0008] Preferably, the hot stamping assembly includes a moving groove longitudinally formed on the top surface of the support frame, a locking block slidably connected in the moving groove, and a first cylinder longitudinally mounted on the rear end of the top surface of the support frame, the output shaft of the first cylinder being fixedly connected to the rear end face of the locking block.

[0009] Preferably, a second cylinder is fixedly connected to the bottom surface of the locking block, and a heating plate with a connecting structure is fixedly connected to the output shaft of the second cylinder.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model achieves efficient flattening and pre-cleaning of canvas through the cooperation of positioning components, rotating rollers, support platforms, and support frames. During the canvas conveying stage, the first and second rotating rollers work together to flatten the canvas in both directions, preventing wrinkles from affecting hot stamping accuracy. A flexible brush cleans lint and other impurities from the canvas surface, reducing impurities and improving the quality of the finished hot stamping product. During the canvas positioning stage, the sliding of the positioning plate within the positioning groove quickly limits the rotating rod, preventing it from shifting during canvas conveying and ensuring stable operation of the rotating rollers. The support system, through the cooperation of the support platform and support frame, provides a stable mounting foundation for the positioning and hot stamping components, adapting to the processing needs of different canvas specifications without requiring a custom-made support frame. All components are connected by bolts to their preset mounting positions, eliminating the need for additional complex supports, reducing the overall space occupied by the equipment and the number of components, and meeting the requirements of canvas processing for compact structure and stable operation.

[0011] 2. This utility model achieves precise adjustment of the hot stamping position and efficient hot stamping operation through the cooperation between the hot stamping component and the drive structure. The first cylinder in the support frame drives the locking block to move longitudinally along the moving groove, and cooperates with the second cylinder to drive the hot stamping plate to rise and fall, meeting the hot stamping needs of different positions and depths. The combination of the heating plate and the heat-conducting hot stamping plate quickly transfers heat to ensure stable hot stamping temperature. The stepper motor drives the lead screw to rotate through the coupling, driving the moving table to move smoothly along the guide rod, so that the brush and the second rotating roller follow the canvas conveying rhythm synchronously, continuously cleaning and assisting in flattening, improving the connection efficiency between pretreatment and hot stamping. The protective cover protects the stepper motor to prevent impurities from entering during processing and affecting the motor operation, thus extending the motor's service life. It improves the control flexibility of the entire equipment for the canvas hot stamping position and can effectively ensure the stability of the hot stamping process, avoiding processing interruptions or defective products caused by component failure.

After cleaning, the first cylinder 15 is activated to move the locking block 14 through the sliding groove opened on the inner top surface of the support frame 5 to the predetermined position. When the locking block 14 reaches the predetermined position, the second cylinder 16 is activated. The second cylinder 16 drives the heating block and the hot stamping plate 17 to move towards the top surface of the canvas to hot stamp the canvas surface. After the hot stamping is completed, the second cylinder 16 and the first cylinder 15 are reset. Then, the external winding assembly is activated to wind up the canvas and then the subsequent hot stamping begins.
