Description

Technical Field

[0001] The utility model relates to the technical field of screen printing machines, in particular to a printing screen for a screen printing machine. Background Art

[0002] A screen printer is a machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate mounting, inking, embossing, and paper feeding (including folding). Its working principle is: first, the text and image to be printed are made into a printing plate, which is then mounted on a printing press. Then, ink is applied to the places on the printing plate where the text and image are, either manually or by a printing press, and then directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood boards, glass, and ceramics), thereby replicating a printed product identical to the printing plate.

[0003] For example, the patent document with application number 202021963169.4 discloses a screen printing machine printing screen. The utility model discloses a screen printing machine printing screen, including a fixed frame, one end of the top of the fixed frame is rotatably connected to a transmission shaft through a bearing, and the transmission shaft is fixedly connected to a connecting rod in the middle of the internal position of the fixed frame. The number of the connecting rods is two, and one end of the opposite surface of the two connecting rods is fixedly connected to a driving rod, and the surface of the driving rod is movably connected to a movable arm. The utility model uses the driving block to rotate the rotating arm with the transmission shaft as the rotating axis, and the rotating arm drives the driving rod to rotate through the transmission shaft and the connecting rod, and drives the movable arm to move through the driving rod and the driving groove, so that the position between the two fixed blocks becomes larger. At this time, the fixing bar is placed between the two driving rods, and the rotating arm is loosened so that the two fixing blocks are driven and the fixing bar is clamped to complete the operation of fixing the mesh cloth under the action of the telescopic rod and the damping spring, thereby achieving the purpose of facilitating the replacement of the mesh cloth. However, when the screen printing machine prints the screen, if the fixed frame is placed on the surface of the placement plate and it is offset during installation, it will cause waste of the mesh cloth and increase the production cost.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a screen printing machine printing screen is proposed. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 2 As shown, a screen printing machine printing screen includes a placement plate 1 with slide grooves 2 on both sides of the upper end surface, and a limit push plate 202 is slidably installed inside the slide groove 2. The advantage of this arrangement is that through the arrangement of the limit push plate 202, a bidirectional threaded rotating rod 204 can be used to control the limit push plate 202 to push the support frame 4 placed on the surface of the placement plate 1 to align it, thereby avoiding waste of resources when laying the mesh cloth due to the offset of the support frame 4.

[0022] Furthermore, a support frame 201 is provided at the rear end of the limit push plate 202, and a bidirectional threaded rotating rod 204 is spirally installed in the middle of the surface of the support frame 201, a rotating cover 205 is provided at the front end of the bidirectional threaded rotating rod 204, and the bidirectional threaded rotating rod 204 passes through the two side surfaces of the placement plate 1 and is connected to the other end. The advantage of this arrangement is that through the arrangement of the bidirectional threaded rotating rod 204, the limit push plates 202 on both sides of the placement plate 1 can be driven to move synchronously.

[0023] Furthermore, a limiting slide bar 203 is provided on both sides of the surface of the support frame 201, and the limiting slide bar 203 is arranged on both side surfaces of the placement plate 1. The advantage of this arrangement is that the support frame 201 can be limitedly slid by the arrangement of the limiting slide bar 203.

[0024] Furthermore, a support frame 4 is installed on the surface of the placement plate 1, and a mesh cloth is arranged on the surface of the support frame 4. This arrangement is an existing device and will not be described in detail.

[0025] like Figure 3 As shown, the four corners of the upper surface of the placement plate 1 are provided with slide grooves 2 3, and a limiting slider 302 is slidably installed inside the slide grooves 2 3. The upper end of the limiting slider 302 is provided with a support frame 2 301, and the inner wall of the support frame 2 301 is provided with a slide groove 303. The advantage of this arrangement is that through the setting of the slide grooves 2 3, the position of the sliding pressure plate 304 can be controlled according to the size of the support frame 4, so as to fix the mesh cloth on the support frame 4.

[0026] Furthermore, a sliding pressure plate 304 is slidably installed inside the slide groove 303, and a limiting slide rod 2 307 is set in the middle of the upper end surface of the sliding pressure plate 304, and a lifting plate 308 is set at the upper end of the limiting slide rod 2 307, and the lifting plate 308 is slidably connected to the support frame 2 301. The advantage of this arrangement is that the sliding pressure plate 304 can be lifted by the setting of the lifting plate 308.

[0027] Furthermore, telescopic rods 305 are arranged on both sides of the surface of the sliding pressure plate 304, and compression springs 306 are arranged on the surface of the telescopic rods 305. The advantage of this arrangement is that, through the arrangement of the compression springs 306, the mesh cloth can be quickly fixed after being laid on the surface of the support frame 4, thereby speeding up the installation.

[0028] Working principle: When using the screen printer to print the screen, first, place the support frame 4 on the surface of the placement plate 1, and then rotate the rotating cover 205 to drive the bidirectional threaded rotating rod 204 to rotate. At the same time, the support frame 1 201 on the surface of the bidirectional threaded rotating rod 204 moves forward, so that the limit push plate 202 finds the support frame 4 along the slide groove 1 2. After placing the mesh cloth on the surface of the support frame 4, pull the lifting plate 308 to lift the sliding plate 304 through the limit slide rod 2 307. After moving the support frame 2 301 along the slide groove 2 3 to the top of the support frame 4, release the lifting plate 308, and the compression spring 306 drives the sliding plate 304 to reset and fix the mesh cloth. This is the working principle of the screen printer.
