The frame 22 in this embodiment is shown in fig. 6, and includes a frame 22 and a steel mesh 23 in the middle of the frame 22 for precision plate making.
Step 2: pre-fixing a silk screen: the silk screen 21 is flatly and uniformly laid on the screen stretching mechanism, the distance between the clamping legs 30 and the silk screen chuck base 35 is reduced by rotating the handle 29, the edge of the silk screen 21 is fixed between the clamping legs 30 and the silk screen chuck base 35, and therefore the four sides of the silk screen 21 are clamped, and the silk screen 21 is stretched in the four directions. When the screen is stretched, the four sides of the screen 21 are at the same horizontal height, and the tension on each position of the screen 21 is uniformly distributed. The screen 21 is a non-metal screen, and in this embodiment, silk is selected.
The six adjusting parts are respectively adjusted to make the silk screen 21 tightened to the periphery to reach the required tightness. Taking the adjusting part in fig. 1 as an example, the screw 36 is rotated to move the nut 37 rightward, the nut 37 moves rightward to drive the screen chuck base 35 to move rightward, and the screen chuck base 35 moves rightward to drive the right edge of the screen 21 to move rightward, so as to tighten the screen 21. In the embodiment, the moving distance of the screen chuck base is controlled by controlling the rotating speed of the bolt 36, so that the condition that the tensile force distribution of the screen 21 is uneven due to the unequal moving distance of the screen chuck base 35 is avoided; the screen 21 tension was measured using a HT-6510N digital screen tensiometer.
And 5, fixing the middle part of the silk screen. Threaded rod 2 in this scheme rotates when driving blade 20 and moves down, still can drive rim plate 3 and move down, when blade 20 moves down silk screen 21 place height, the shrinkage pool of rim plate 3 just supports and leans on the upper surface of connection piece 17, the peripheral downward extrusion with connection piece 17, make and fix and be the arc motion at the peripheral couple of connection piece 17 to the direction of threaded rod 2, so the couple can insert in the silk screen and hook the silk screen, so the silk screen 21 that lies in the middle part of the screen frame 22 is in the state of tightening all the time, can not appear cutting knife 15 and begin the cutting back, the part that silk screen 21 was cut off will lose the effort of tightening that the net mechanism gave. If there is no hook to hook the middle of the screen 21, taking fig. 2 as an example, after the cutting knife 15 cuts horizontally along the upper portion of the rail 33 and then cuts vertically along the right side of the rail 33, when the cutting knife 15 cuts leftwards along the lower side of the rail 33, there may occur that the upper side of the screen 21 is not tightened to cause the cut edge to be irregular or not cut just close to the edge of the steel net 23; as the cutting blade 15 continues to move up the left side of the rail 33, it is easy for the wire 21 to be completely spread on the steel mesh 23, so that the cutting blade 15 cannot cut the wire 21. No matter how far the cutting knife 15 cuts along the rail 33, the part of the screen 21 which is not cut is always in a tightening state, so the cutting knife 15 can cut the screen 21 along the edge of the steel net 23 in preparation.
Moreover, the threaded rod 2 rotates to drive the blade 20 to move downwards, and simultaneously drives the connecting sheet 17 to rotate together, so as to drive the hook to rotate, and in the process of cutting a circle by the cutting knife 15, the hook can drive the partial silk screen 21 hooked by the hook to twist a circle, so that the middle part of the screen frame 22 is tightened with the silk screen 21, and the cutting of the cutting knife 15 is facilitated.
And 6, cutting the silk screen. The starting motor 4 enables the threaded rod 2 to start to rotate anticlockwise, and the connecting rod 12 extends out through the second sliding groove 9, so that the condition that the wheel disc 3 rotates along with the threaded rod 2 is limited, and the wheel disc 3 can move downwards all the time. The wheel disc 3 moves downwards to drive the connecting rod 12 to move downwards together, the connecting rod 12 drives the cutting knife 15 to move downwards, and then the blade 20 is driven to move downwards to the position of the silk screen 21 to cut the silk screen 21.
When the blade 20 is moved down to the position of the screen 21, the connecting rod 12 is moved down below the sleeve 5, and the wedge 18 is inserted into the locking hole 11 to clamp the wheel disc 3 and the connecting piece 17 to each other, and at this time, the pawl 10 is still in the first sliding groove 8 as shown in fig. 8, but because the pawl 10 is engaged in one direction, the rotation of the wheel disc 3 together with the connecting piece 17 is not affected. The wheel disc 3 and the link plate 17 rotate together with the threaded rod 2 counterclockwise, and the link rod 12 rotates together with the wheel disc 3 counterclockwise (counterclockwise here is based on fig. 2). However, since the upper end of the cutting blade 15 is slidably connected in the rail 33 and the groove 14, the cutting blade 15 moves along the rail 33 along with the rotation of the connecting rod 12, thereby driving the blade 20 to cut the screen 21 along the edge of the steel net 23.
And 7, returning the blade. After the cutting knife 15 finishes cutting the silk screen 21, the motor 4 is rotated reversely to drive the threaded rod 2 to rotate clockwise, the threaded rod 2 drives the connecting piece 17 to rotate clockwise (taking the picture 2 as a reference), and when the wheel disc 3 rotates clockwise along with the connecting piece 17, the pawl 10 can be blocked by the side wall of the first sliding groove 8, so that the wheel disc 3 is blocked by the sleeve 5, and the wheel disc 3 cannot rotate clockwise along with the connecting piece 17. The wheel 3 will rotate relative to the threaded rod 2 so that the wheel 3 will slide back up under the rotation of the threaded rod 2.
