When it is necessary to fix the screen printing plates of different specifications and thicknesses, first rotate the screw 42 on the L-shaped plate 41, and the screw 42 moves with the limit plate 43. When the limit plate 43 is moved to the appropriate position, the staff places the screen printing plate inside the U-shaped frame 1, and then open the cylinder 2. The cylinder 2 moves the clamping plate 3 in the direction of the screen printing plate, and the clamping plate 3 moves with the L-shaped plate 41 and the limit plate 43 in the direction of the U-shaped frame 1. Finally, the limit plate 43 is against the surface of the U-shaped frame 1, achieving the effect of limiting the maximum displacement of the clamping plate 3.

[0031] Reference Figure 1-4As shown, the auxiliary device 5 includes a rubber pad 51, which is arranged on the side of the clamping plate 3 away from the cylinder 2. The two sides of the rubber pad 51 are fixedly connected with a mounting plate 52. The surface of the mounting plate 52 is slidably penetrated by two plug rods 53. One end of the two plug rods 53 is fixedly connected with the same fixed plate 55. The clamping plate 3 is provided with a plug hole 54 corresponding to the plug rod 53. The size of the plug hole 54 is adapted to the size of the plug rod 53. When the rubber pad 51 needs to be installed, the staff first moves the rubber pad 51 to the bottom of the clamping plate 3, and then moves the fixed plate 55. The fixed plate 55 carries the plug rod 53 through the mounting plate 52 and inserts it into the plug hole 54 of the clamping plate 3, so as to achieve the effect of fixing the mounting plate 52 and the rubber pad 51. The rubber pad 51 arranged by the auxiliary device 5 increases the friction between the clamping plate 3 and the screen printing plate, so as to prevent the clamping plate 3 and the screen printing plate from sliding. At the same time, when the rubber pad 51 is damaged, it is convenient for the staff to quickly replace the rubber pad 51, which brings convenience to the staff.
[0032] Reference Figure 1-4 As shown, a spring 57 is fixedly connected to one side of the fixing plate 55, and one end of the spring 57 is fixedly connected to the mounting plate 52. When the fixing plate 55 is away from the mounting plate 52, the spring 57 is deformed. When the two mounting plates 52 are moved to the two sides of the clamping plate 3, the staff loosens the fixing plate 55. Under the action of the spring 57's resetting elastic force, the plug rod 53 is automatically inserted into the plug hole 54 of the clamping plate 3, which brings convenience to the staff to fix the rubber pad 51 and prevents the plug rod 53 from moving out of the plug hole 54. A pull plate 56 is fixedly connected to one side of the fixing plate 55, and the cross section of the pull plate 56 is "L" shaped. By setting the pull plate 56, the effect of facilitating the staff to move the fixing plate 55 is achieved, which brings convenience to the staff. A sharp protrusion 58 is fixedly connected to one end of the plug rod 53, and the tip of the sharp protrusion 58 is away from the plug rod 53. By setting the sharp protrusion 58, it is convenient for the staff to insert the plug rod 53 into the plug hole 54 of the clamping plate 3, which brings convenience to the staff.
[0033] Working principle: When it is necessary to fix screen printing plates of different specifications and thicknesses, firstly, the screw 42 on the L-shaped plate 41 is rotated by the handle 48, and the screw 42 moves with the limit plate 43, and the slider 44 of the limit plate 43 moves in the slide groove 45 of the L-shaped plate 41 to limit the moving direction of the limit plate 43. The staff judges the position of the limit plate 43 by the position of the scale 47 pointed by the pointer 46 of the limit plate 43, so that the distance between the limit plate 43 and the horizontal end of the L-shaped plate 41 is adapted to the thickness of the screen printing plate. When the limit plate 43 is moved to the appropriate position, the staff places the screen printing plate on the U The inside of the U-shaped frame 1 is opened at this time, and the cylinder 2 is opened, and the cylinder 2 moves the clamping plate 3 toward the screen printing plate, and the clamping plate 3 moves toward the U-shaped frame 1 with the L-shaped plate 41 and the limit plate 43, and finally the limit plate 43 is against the surface of the U-shaped frame 1, thereby achieving the effect of limiting the maximum displacement of the clamping plate 3. At this time, the clamping plate 3 also happens to squeeze the screen printing plate, thereby achieving the effect of fixing the screen printing plate. The limit device 4 is used to limit the maximum displacement of the clamping plate 3, which is convenient for the staff to fix the screen printing plates of different specifications and thicknesses, and avoids the situation where the cylinder 2 is too strong, causing the clamping plate 3 to damage the screen printing plate.
[0034] When the rubber pad 51 needs to be installed, the staff first moves the rubber pad 51 to the bottom of the clamping plate 3. At this time, the fixing plate 55 is moved away from the mounting plate 52 by the pulling plate 56. The spring 57 is deformed. When the insertion rod 53 is aligned with the insertion hole 54 of the clamping plate 3, the staff releases the pulling plate 56. Under the action of the restoring elastic force of the spring 57, the insertion rod 53 passes through the mounting plate 52 with the help of the pointed protrusion 58 and is inserted into the insertion hole 54 of the clamping plate 3, thereby achieving the effect of fixing the mounting plate 52 and the rubber pad 51. The rubber pad 51 set by the auxiliary device 5 increases the friction between the clamping plate 3 and the screen printing plate to prevent the clamping plate 3 and the screen printing plate from sliding. At the same time, when the rubber pad 51 is damaged, it is convenient for the staff to quickly replace the rubber pad 51, which brings convenience to the staff.
