Description

Technical Field

[0001] The utility model relates to the technical field of screen printing, in particular to a screen printing plate frame structure with automatic alignment. Background Technique

[0002] Screen printing is a relatively traditional printing technology. However, screen printing can use inks that are bright in color, light-fast, and water-resistant, and is suitable for indoor and outdoor applications. Moreover, screen printing can be applied to different materials, including uneven surfaces. Therefore, screen printing is still applied in various industries and products.

[0003] Generally, in screen printing, the printing screen is fixed to the plate frame with glue, and then the plate frame is placed on the printing object. Ink is applied to the screen, and a squeegee is moved horizontally on the screen to complete the printing of the printing object. However, as the printing time increases, the screen is continuously stressed and becomes loose, which will reduce the quality of the printed product. For this reason, a structure of an alignment screen printing machine is provided (specifically refer to the patent number: 202222515411.7), including a screen plate frame. A printing screen is arranged inside the screen plate frame. A first installation groove is opened at one end of the screen plate frame, and a second installation groove is opened at the other end. A tensioning shaft is movably installed inside the first installation groove. A servo motor is fixedly installed on the front surface of the screen plate frame. In this structure of the alignment screen printing machine, the printing screen is installed inside the screen plate frame through the tensioning shaft and the clamping mechanism. When the printing screen is in a tensioned state, pressure is applied to the pressure sensor. The tensioning force is detected by the pressure sensor and fed back to the microcontroller. When the tensioning force becomes small, the microcontroller can control the servo motor to drive the tensioning shaft to rotate and re-tension the printing screen to ensure that the printing screen is always in a tensioned state during printing.

[0004] However, when placing the printing object on the existing screen printing machine, errors are likely to occur, and the printing object is placed crookedly, which affects the quality of the printed finished product and causes waste of resources. When installing the screen, the screen may also be skewed, thus affecting the printing quality. Moreover, the structure is relatively complex, and later maintenance, replacement, and cleaning are all relatively troublesome. Content of the Utility Model

[0005] The purpose of the utility model is to provide a screen printing plate frame structure with automatic alignment to solve the problems that the printing object may be placed crookedly, affecting the quality of the printed finished product and causing waste, as well as the complex installation of the printing screen, which may be installed crookedly and is relatively troublesome for maintenance and replacement.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A screen printing plate frame structure with automatic alignment, including:

[0007] A fixing component for fixing the equipment;

[0008] The feeding component is located on one side of the fixed component and is detachably connected to it;

[0009] The printing component is located on the top of the fixed component;

[0010] The fixed component includes a rotating shaft. A first fixing rod is provided at the middle position of the rotating shaft, and second fixing rods are provided at both ends of the rotating shaft. The feeding component includes a feeding plate. A first stud is provided at the middle position of the bottom of the feeding plate. A rotating rod is provided outside the first stud. A dial rod is provided at one end of the rotating rod.

A movable shaft is provided on the adjacent end face of the two groups of mounting heads. A rotating cylinder is sleeved outside the movable shaft. A wire mesh is wound around the outside of the rotating cylinder. A pulling plate is provided at the top of one side of the wire mesh.

[0011] As a further scheme of the present utility model: The first fixing rod is detachably connected to one side of the feeding plate through a bolt. The two second fixing rods are both detachably connected to both ends of the frame through bolts. The first fixing rod and the two second fixing rods are both rotatably connected to the rotating shaft through bearings.

[0012] As a further scheme of the present utility model: The rotating rod is rotatably connected to the feeding plate through the first stud. The two groups of link rods are both rotatably connected to the rotating rod through the second studs.

[0013] As a further scheme of the present utility model: Multiple groups of movable grooves penetrating to the bottom are evenly provided on the top of the feeding plate. The number of the movable grooves is two. The two screw rods are both movably connected to the feeding plate through the movable grooves. The tops of the two screw rods are welded to the bottoms of the two sliders.

[0014] As a further scheme of the present utility model: Chute grooves are provided on both sides of the top of the feeding plate. The two sliders are both movably connected to the feeding plate through the chute grooves.

[0015] As a further scheme of the present utility model: Limit grooves are provided at both ends inside the frame. The pulling plate is movably connected to the frame through the limit grooves.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] 1. With the feeding component provided, during use, turn the lever clockwise, which drives the rotating rod to rotate clockwise. While the left connecting rod rotates counterclockwise, it moves to the left, and while the right connecting rod rotates clockwise, it moves to the right. As a result, the two sets of sliders are driven to move to both ends of the feeding plate. Place the printed matter on the feeding plate, and then turn the lever counterclockwise to drive the two sets of sliders to move towards the middle. When the sliders touch the printed matter, continue to turn the lever. Under the pressure of the two sets of sliders, the printed matter is squeezed straight. Then turn the lever clockwise to move the two sets of sliders to both ends. This operation ensures that the printed matter will not produce defective products due to skewed placement, guarantees the printing quality, and does not waste resources.

[0018] 2. With the printing component provided, one side of the silk screen wound around the rotating cylinder is installed at the bottom of the pulling plate. Then pull the pulling plate to the side of the plate frame away from the rotating cylinder, driving the silk screen to be neatly laid at the bottom of the plate frame to complete the installation operation. During use, turn the second fixing rod clockwise to drive the printing component to rotate clockwise around the rotating shaft to the top of the feeding plate. Then apply ink on the silk screen, place the squeegee on the top of the silk screen and move it horizontally. Then turn the second fixing rod counterclockwise to return the printing component to its original position to complete the printing operation. After long-term use, pull the pulling plate to the side of the plate frame close to the rotating cylinder, and then remove the rotating cylinder to clean or replace the silk screen. This structure is simple to install, convenient for maintenance, can ensure that the silk screen is not installed skewed, and guarantees the printing quality. BRIEF DESCRIPTION OF THE DRAWINGS
