Description

Technical Field

[0001] This utility model belongs to the field of marking device technology, specifically relating to a device that can print markings at both ends in one go. Background Technology

[0002] In industrial production, pad printing for marking straight pipe components is a common and important process. Accurate and clear markings not only facilitate product traceability and management but also provide crucial information during installation, use, and maintenance. However, existing pad printing processes have significant limitations when the markings at both ends of a straight pipe are not on the same plane. Traditional pad printing methods for such straight pipes typically require two steps: first, marking one end of the pipe, then flipping it over and repeating the same operation on the other end. While this step-by-step method is simple and direct, it faces numerous problems in practice. Inaccurate positioning is the primary challenge of step-by-step pad printing. Because the two ends of the straight pipe are not on the same plane, it is difficult to ensure that the repositioning after flipping is completely consistent with the initial marking. This slight deviation can lead to information misalignment in situations with strict marking requirements. To compensate for this deficiency, workers often need to pre-draw positioning lines on a fixture and manually compare them to ensure the accuracy of the pad printing position. This not only increases the complexity of the operation but also places higher demands on the skills and experience of the workers. Increased production steps are another major drawback of step-by-step pad printing. Each pad printing process requires additional steps such as flipping, repositioning, and drawing lines. These steps are not only time-consuming and labor-intensive, but also prone to introducing new sources of error. Especially in mass production, these seemingly minor additional processes can accumulate into significant time costs, leading to low production efficiency and an inability to meet market demands for rapid delivery. Utility Model Content

[0003] (1) Technical problems to be solved To address the shortcomings of existing technologies, the purpose of this invention is to provide a device for one-time pad printing of markings at both ends. This addresses the problem that existing techniques often require workers to pre-draw lines on a fixture and manually compare them to ensure accurate pad printing positions. This not only increases operational complexity but also places higher demands on worker skills and experience.

[0004] (2) Technical solution To solve the above-mentioned technical problems, this utility model provides a device for one-time pad printing of markings at both ends, including a base plate, a mounting tube, and a straight tube. The straight tube is installed inside the mounting tube, and a support block is provided below the mounting tube. The mounting tube rotates and moves inside the support block. The support block is fixedly installed on the upper surface of the base plate, and a fixing block is also provided on the side of the base plate. The fixing block is fixedly connected to the base plate, and an inner sliding rod slides through the inside of the fixing block. The end of the inner sliding rod is fixedly connected to the side wall of the mounting tube.

[0005] Preferably, the mounting tube is a semi-circular tube structure, and the straight tube is embedded in it.

[0006] Preferably, the outer wall of the straight pipe is provided with a first mark and a second mark that are spaced apart.

[0007] Preferably, the fixing block has a sliding hole inside, and the inner sliding rod passes through the sliding hole.

[0008] Preferably, the upper surface of the support block is recessed to fit the arc-shaped structure of the outer wall of the mounting tube, and the inner wall of the support block has an inner sliding groove.

[0009] Preferably, a slider is provided on the outer wall of the mounting tube. The slider is adapted to slide along the inner groove. The slider slides along the inner groove, causing the mounting tube to turn left and right during the movement.

[0010] Preferably, a handle is fixedly connected to the end of the inner slide rod away from the mounting tube.

[0011] (3) Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, through precise positioning, utilizes a special structural design of the support block and mounting tube, along with the adaptive sliding of the slider and inner groove, to ensure the stability and positioning accuracy of the straight tube during the transfer printing process. Even if the markings at both ends of the straight tube are not on the same plane, accurate transfer printing of the markings at both ends can be achieved in a single operation. This avoids the positioning inaccuracies caused by flipping and repositioning in traditional step-by-step transfer printing methods, effectively improving the quality and clarity of the markings and reducing quality issues such as information misalignment. It achieves one-time transfer printing of markings at both ends of the straight tube without the need for flipping and repositioning, significantly reducing production steps. According to feedback from actual applications, using this device can increase production efficiency by more than double, meeting the demands of large-scale production for rapid delivery and effectively reducing time costs.

[0012] Traditional step-by-step pad printing requires highly skilled and experienced workers. Accurate pad printing positions are ensured by pre-marking lines on a fixture, making the process complex and prone to human error. This device achieves accurate positioning of the straight tube through a mechanical structure, reducing the skill requirements for workers, minimizing errors caused by manual operation, and improving production stability and consistency.
