DETAILED DESCRIPTION
[0024] The embodiments of the present invention will be described below with reference to the accompanying drawings.
[0025] Example 1
[0026] A screen printing machine with convenient screen replacement, see Figure 1-Figure 4 and Figure 6 As shown, it includes an operating table 2, a support base 1, a screen frame 3, a screen printing screen 4, a motor 5, a bidirectional screw 6, a sliding block 7 and a clamping ring 8. The support base 1 is provided on both the left and right sides of the bottom of the operating table 2 by bolt connection. The screen frame 3 is placed on the operating table 2, and the screen printing screen 4 is embedded in the screen frame 3. The motor 5 is embedded on the left side of the operating table 2. The output shaft of the motor 5 is provided with a bidirectional screw 6 through a coupling. Two sliding blocks 7 are threadedly provided on the bidirectional screw 6. The sliding block 7 is provided with a clamping ring 8 for clamping the screen frame 3 by welding.
[0027] When the screen printing screen 4 of the screen printing machine needs to be replaced, the staff places the support seat 1 on the workbench, and then the staff turns on the motor 5. The output shaft of the motor 5 rotates to drive the bidirectional screw 6 to rotate, and then the sliding block 7 drives the clamping ring 8 to move outward and disengage from the screen frame 3. The staff controls the output shaft of the motor 5 to stop rotating, and then the staff removes the screen frame 3 from the operating table 2. The staff places the new screen frame 3 on the operating table 2, and the staff controls the output shaft of the motor 5 to reverse, and then the sliding block 7 drives the clamping ring 8 to move inward to clamp the screen frame 3, thereby facilitating the replacement of the screen printing screen 4.
[0028] Example 2
[0029] Based on Example 1, see Figure 1 , Figure 4 and Figure 5 As shown, it also includes a first fixed block 9, a connecting rod 11, a handle 10, a support block 12, a threaded rod 13 and a pressure block 14. Two first fixed blocks 9 are provided on the front and rear sides of the operating table 2 by bolt connection. A connecting rod 11 is rotatably provided between the two first fixed blocks 9. The left end of the connecting rod 11 is provided with a handle 10 by welding. Support blocks 12 are provided on both ends of the connecting rod 11 by welding. The threaded rod 13 is threadedly provided inside the support block 12. A pressure block 14 for clamping the screen frame 3 is provided at the lower end of the threaded rod 13 by welding.
[0030] When the clamp ring 8 moves outward and loses contact with the screen frame 3, the staff member rotates the threaded rod 13 upward to make the pressure block 14 move upward and lose contact with the screen frame 3, then the staff member holds the handle 10 by hand to rotate the connecting rod 11, thereby driving the support block 12 to rotate outward, and then the staff member removes the screen frame 3 from the operating table 2 to change the material of the silk screen 4. After the material change is completed, the staff member puts the screen frame 3 back on the operating table 2, the staff member holds the handle 10 by hand to reverse the connecting rod 11, thereby driving the support block 12 to rotate inward and reset, and the staff member rotates the threaded rod 13 downward to make the pressure block 14 move downward to clamp the screen frame 3 for the second time, thereby improving the stability of the screen frame 3.
[0031] See also Figure 1 , Figure 6 and Figure 7 As shown, it also includes a second fixed block 15, a connecting block 16, a rotating rod 17, a pressure ring 18 and a handle 19. The second fixed block 15 is arranged on the rear side of the operating table 2 by welding, and the connecting block 16 is arranged on the second fixed block 15 by welding. The connecting block 16 is rotatably provided with a rotating rod 17 inside, and a pressure ring 18 for pressing the screen frame 3 is arranged on the rotating rod 17 by welding. The pressure ring 18 can completely press the screen frame 3, and the front side of the pressure ring 18 is provided with a handle 19 by welding.
[0032] When the support block 12 rotates outward to a suitable angle, the staff holds the handle 19 by hand and rotates the pressure ring 18 upward to disengage the screen frame 3. The staff then removes the screen frame 3 from the operating table 2 to replace the screen 4. After the material replacement is completed, the staff holds the handle 19 by hand and rotates the pressure ring 18 downward to press the screen frame 3 to further improve the stability of the screen frame 3. The staff then clamps the screen frame 3 for a second time.
[0033] See also Figure 1 and Figure 6As shown, a threaded nail 20 is also included, and the support seat 1 is internally provided with a threaded nail 20 for fixing by welding.
[0034] When the support base 1 contacts the workbench, the threaded nails 20 are inserted into the ground, thereby increasing the pressure between the support base 1 and the workbench and improving the stability of the support base 1.
[0035] See also Figure 1 and Figure 4 As shown, a rubber block 21 is also included. A rubber block 21 for protection is embedded at the bottom of the pressing block 14 .
[0036] When the pressing block 14 fixes the screen frame 3 , the rubber block 21 plays a protective role to prevent the pressing block 14 from causing wear on the surface of the screen frame 3 .
[0037] See also Figure 1 and Figure 2 As shown, a protective shell 22 is also included. A protective shell 22 for protection is set on the left side of the operating table 2 by welding. The protective shell 22 is made of hard iron material and can achieve better protection effect. The motor 5 is located inside the protective shell 22.
[0038] The protective shell 22 plays a protective role, preventing the motor 5 from being exposed to the outside and being damaged.
