[0019] 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.

[0020] Example

[0021] Depend on Figure 1-3 Provided is a printing screen that is easy to replace, comprising a printing machine body 1 and a printing screen 3;

[0022] A support frame 11 is mounted on one side of the upper end surface of the printer body 1, a screw seat 12 is mounted on one side of the support frame 11, two connecting frames 13 are mounted on one side of the screw seat 12, and the two connecting frames 13 are arranged in parallel, and a set of limit assemblies 2 are mounted on one side of the two connecting frames 13, and the two sets of limit assemblies 2 are arranged in parallel opposite to each other;

[0023] The limit assembly 2 includes a mounting seat 20, a positioning block 21 is installed on one side of the mounting seat 20, the positioning block 21 has a sliding cavity and two sliders 22 are slidably arranged in the sliding cavity, an opening is arranged on the upper end surface of the positioning block 21, the upper end surfaces of the two sliders 22 are equipped with mounting plates 23 and the two mounting plates 23 are located at the upper opening of the positioning block 21, and a threaded rod 24 is penetrated on one side of the two mounting plates 23, the two threaded rods 24 are arranged in opposite parallel and are jointly equipped with a sleeve 25 on the outside, and the sleeve 25 is provided with positive and negative threads and is meshed with the two threaded rods 24 through threads.

[0024] In this embodiment, through the mutual cooperation between the components in the two groups of limit assemblies 2, the staff can rotate the two sleeves 25 so that the two sliders 22 slidingly set in the positioning block 21 are driven to move in the center, so that the locking block 221 cancels the limit on the circular block 31, and the printing screen 3 can be quickly disassembled, which greatly shortens the time for replacing the printing screen 3 and improves the printing efficiency of the printing machine body 1. Compared with the traditional threaded fixing method, the device can reduce the labor intensity of disassembling and installing the printing screen 3, so that the staff does not need to use special tools to remove the bolts, thereby reducing physical exertion. The rapid replacement of the printing screen 3 allows the printing machine body 1 to switch to different printing tasks, thereby improving production efficiency and flexibility.

[0025] Specifically, refer to Figure 2-3 A limit block 201 is respectively installed at both ends of one side of the mounting seat 20. The two limit blocks 201 both have a rectangular cavity with an opening on the inner side. The outer ends of the two sliders 22 are both equipped with a snap-fit ​​block 221, and the snap-fit ​​block 221 on the same side corresponds to the size of the inner opening of the limit block 201 on the same side.

[0026] In this embodiment, when the slider 22 is driven to move, the engaging block 221 installed at one end is driven to move toward an opening on one side of the limit block 201 and inserted into the limit block 201, thereby engaging and limiting the circular block 31 installed in the limit block 201.

[0027] Specifically, refer to Figure 3 The two mounting plates 23 are both equipped with a sliding sleeve 231 , and the mounting plate 23 on the same side is meshed and connected with the threaded rod 24 on the same side through the sliding sleeve 231 .

[0028] In this embodiment, the mounting plate 23 is meshed and connected with the threaded rod 24 through a sliding sleeve 231. When the threaded rod 24 rotates, the positioning block 21 limits the slider 22, so that the mounting plate 23 installed on the upper end of the slider 22 can drive the slider 22 to slide within the sliding cavity travel range of the positioning block 21.

[0029] Specifically, refer to Figure 3 The outer ends of the two threaded rods 24 are both equipped with limit plates 241.

[0030] In this embodiment, the limiting plate 241 is used to limit the mounting plate 23 to prevent the mounting plate 23 from exceeding the travel range of the threaded rod 24 .

[0031] Specifically, refer to Figure 3 The sleeve 25 is provided with anti-skid patterns on the outside.

[0032] In this embodiment, by providing anti-slip patterns on the outside of the sleeve 25, the staff can more easily rotate the sleeve 25, thereby increasing convenience.

[0033] Specifically, refer to Figure 2-3 Four circular blocks 31 are arranged on the outer side of the printing screen 3 and the four circular blocks 31 are distributed in a rectangular shape.

[0034] In this embodiment, four circular blocks 31 are installed on both sides of the printing screen 3 by welding. When the engaging blocks 221 engage the circular blocks 31, the printing screen 3 can be limited and fixed, and the operation is simple.

[0035] The conveniently replaceable printing screen of the utility model:

[0036] In actual use, when the staff needs to disassemble the printing screen 3, firstly, the two sleeves 25 are held and rotated, so that the two threaded rods 24 meshed with the sleeves 25 are driven to rotate. The sleeves 25 are provided with positive and negative threads. When the two threaded rods 24 rotate, the mounting plate 23 meshed with the threaded rods 24 through the sliding sleeve 231 is driven and the slider 22 connected at the lower end slides in the sliding cavity of the positioning block 21, and finally the two sliders 22 are driven to move in the center, so that the engaging block 221 at one end of the slider 22 is separated from the limit block 2 01, so that the circular block 31 is unfastened, and then the printing screen 3 is picked up and lifted upward, and the printing screen 3 can be disassembled. When the printing screen 3 needs to be installed, the four circular blocks 31 are aligned with the four limit blocks 201, and the printing screen 3 is installed downward, and then the sleeve 25 is rotated in the opposite direction, so that the two threaded rods 24 are driven to rotate, so that the two sliders 22 are driven to move outward, so that the locking block 221 at one end of the slider 22 moves to the side of the limit block 201 and is finally inserted into the circular block 31, thereby completing the installation limit of the printing screen 3.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
