Description

TECHNICAL FIELD

[0001] The utility model relates to panel printing technical field, concretely is a kind of printing screen board positioning device. BACKGROUND

[0002] In the field of panel printing, the traditional logo printing method usually relies on the gold stamping process. This process requires the use of a gold stamping machine and gold stamping paper, which transfers the metal foil to the panel through high temperature and pressure to form a logo pattern with metallic luster. However, this process has many limitations and challenges.

[0003] In order to address these challenges, there has been a trend in recent years to use printing processes instead of gold stamping processes. The printing process transfers ink to the panel through the screen plate to form the desired logo pattern. This process not only has lower cost, but also is easier to realize automated production, improving production efficiency.

[0004] In the above printing process, the printing screen plate positioning device plays a crucial role. It is responsible for accurately positioning the screen plate on the panel to ensure that the printed logo pattern is accurately positioned and shaped.

[0005] Technical defects of the prior art:

[0006] Insufficient positioning accuracy: The traditional gold stamping process often has insufficient positioning accuracy when positioning the logo pattern due to the need for manual operation. This results in the printed logo pattern being misaligned and deformed, affecting the overall aesthetic of the product.

[0007] Low production efficiency: The gold stamping process requires a lot of time and manpower, and each positioning needs to be adjusted again, resulting in low production efficiency. This increases the production cost of enterprises and reduces market competitiveness. INVENTION CONTENTS

[0010] On the basis of the above technical solutions, the utility model further can make improvement as follows.

[0011] Further, the panel conveying table is provided with a positioning baffle along the conveying path of the panel, and a stop cylinder connected with the positioning baffle.

[0012] Further, the bottom of the center positioning frame is continuously provided with horizontally guiding roller groups distributed at equal intervals.

[0013] Further, the upper surface of the panel conveying table is provided with uniformly and regularly distributed ball bearings.

[0014] Further, the center moving mechanism comprises:

[0017] Further, the center moving mechanism further comprises:

[0018] a transmission belt mounted on the support, the top edge of the transmission belt being connected with the two center positioning frames respectively;

[0019] a motor-driven roller group for driving the transmission belt.

[0020] And, the printing screen board positioning device provided by the utility model has at least the following beneficial effects compared with the prior art:

[0021] The printing screen board positioning device conveys the panel through the panel conveying table, and the center moving mechanism drives the two groups of center positioning frames to move relatively or oppositely, so as to realize the center positioning of the panel. Then, the lifting assembly drives the printing screen board to descend and press the panel, so as to complete the positioning preparation before printing. The positioning baffle and the stop cylinder are used for the preliminary positioning of the front end of the panel, and the ball bearings on the panel conveying table and the horizontally guiding roller groups at the bottom of the center positioning frame are helpful to the smooth conveying and center guiding of the panel.

[0022] The center moving mechanism is composed of the support, the linear guide rail, the transmission belt and the motor-driven roller group. After the motor-driven roller group is started, the transmission belt operates, and drives the two groups of center positioning frames to move relatively or oppositely along the linear guide rail, so as to realize the center positioning of the panel.

DETAILED DESCRIPTION

[0027] The principles and characteristics of the utility model are described below in combination with the drawings, and the examples are only used to explain the utility model and not used to limit the scope of the utility model.

[0028] It should be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connection" and "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or one-piece structure. For ordinary skilled in the art, the specific meaning of such terms in this patent can be understood according to the specific circumstances.

[0029] As shown in Figure 1 and Figure 2 The utility model discloses a printing screen plate positioning device, which comprises a panel conveying table 1, and opposite two groups of centering positioning frames 2 are arranged on both sides of the panel conveying table 1 along a panel conveying path; the panel conveying table 1 is further provided with a centering moving mechanism 3 connected with the two groups of centering positioning frames 2, and the centering moving mechanism 3 is used for driving the two groups of centering positioning frames 2 to move relative to or away from each other; a printing screen plate 4 and a lifting assembly 5 connected with the printing screen plate 4 are arranged above the two groups of centering positioning frames 2, and the lifting assembly 5 is used for driving the printing screen plate 4 to press the panel to be printed.

[0030] When the panel is conveyed on the panel conveying table 1, the two groups of centering positioning frames 2 are driven by the centering moving mechanism 3 to move relative to or away from each other, so as to realize the centering positioning of the panel; then, the lifting assembly 5 drives the printing screen plate 4 to descend and press the panel to be printed, and the positioning preparation before printing is completed.

[0031] As an embodiment, the panel conveying table 1 is further provided with a positioning baffle 6 along the conveying path of the panel, and a stop cylinder 7 connected with the positioning baffle 6.

[0032] The positioning baffle 6 is driven by the stop cylinder 7 to realize the preliminary positioning of the front end of the panel.

[0033] As an embodiment, the bottom of the centering positioning frame 2 is continuously provided with horizontally distributed horizontal guide roller groups 8.

[0034] Specifically, the upper surface of the panel conveying table 1 is provided with evenly and regularly distributed balls 9.

[0035] The balls 9 help reduce friction and make the panel conveying smoother. Meanwhile, the horizontally distributed guide roller groups 8 at the bottom of the center positioning frames 2 are in contact with the side surface of the panel and guide it to the center. Through the adjustment of the center moving mechanism 3, the two center positioning frames 2 move towards or away from each other, ensuring that the panel always remains in the center during the conveying process. Finally, the lifting assembly 5 drives the printing screen plate 4 to descend and press the panel to be printed, completing the precise positioning preparation before printing.

[0041] a motor-driven roller group 3.4 for driving the transmission belt 3.3.

[0042] When the motor-driven roller group 3.4 is started, the transmission belt 3.3 starts to operate and drives the two center positioning frames 2 to move towards or away from each other along the linear guide rail 3.2. Due to the closed-loop design of the transmission belt 3.3, the movement of the two center positioning frames 2 is synchronous and coordinated, thereby realizing the center positioning of the panel. This design not only has a simple structure, but also can realize precise movement control, improving the positioning accuracy and stability of the printing screen plate positioning device.
