[0023] like Figure 1 and Figure 4 As shown, the screen side-pull device comprises a main U-shaped frame 3, a side hanger 4 mounted on the main U-shaped frame 3, and an I-type hydraulic cylinder 5 mounted on the side hanger 4; the I-type hydraulic cylinder 5 is connected to a lower pressing block 6. The lower pressing block 6 can be driven to press the outer extension end of the screen.

[0024] like Figure 4 As shown, the main U-shaped frame 3 is provided with a dovetail side groove 3a for vertically sliding the lower pressing block 6. The above is a conventional design of the sliding structure.

[0025] like Figure 1 and Figure 5 As shown, the screen side-pull device also includes a frame carrier 7 mounted on the work base 1, and double guide rods 8 and an I-type motor 9 both mounted on the frame carrier 7; the I-type motor 9 is connected to a lead screw 10 threadedly matched with the main U-shaped frame 3; the double guide rods 8 are slidably matched with the main U-shaped frame 3. The lead screw 10 is mounted on the frame carrier 7 through a bearing. That is, through the transmission of the lead screw nut, the screen can be pulled open.

[0026] like Figure 3 As shown, a loading rod 2a is provided on the loading seat 2; the loading system includes a type II hydraulic cylinder 11 installed on the working base 1 and a mobile base 12 connected to the type II hydraulic cylinder 11; a clamping plate 13 is welded on the upper end of the mobile base 12.

The lateral frame 27 is provided with a side dovetail groove for slidingly mounting the lower pressing plate 29. That is, before the screen is pulled open and holes are punched, the left part of the screen to be pulled open needs to be fixed.

[0031] When in use, the rolled screen is manually inserted into the loading rod 2a, and the push of the II-type hydraulic cylinder 11 makes the pressing plate 13 cooperate with the loading seat 2 to achieve the front and rear fitting and limiting of the screen.

[0032] Furthermore, the rolled outer extension of the screen is manually pulled to the left below the lower pressing block 6, and the I-type hydraulic cylinder 5 pushes the lower pressing block 6 to achieve the compression of the end of the outer extension of the screen.

[0033] Furthermore, the I-type motor 9 drives the lead screw 10 to rotate, so that the main U-shaped frame 3 moves to the right, thereby pulling the screen open.

[0034] Furthermore, the cylinder 28 pushes down the lower pressing plate 29 to press the left end of the opened portion of the screen.

[0035] Further, the III-type hydraulic cylinder 15 pulls down the lifting platform 14, so that the punching roller 22 descends and the roller needle 23 is inserted to the left side of the part of the screen that is pulled apart, completing a part of the punching.

[0036] Furthermore, the III-type motor 18 drives the spur gear 19 to rotate, causing the punching roller 22 to roll to the right, thereby punching the portion of the entire screen that is pulled apart.

[0037] Finally, the IV-type hydraulic cylinder 24 pushes up the large flat plate 25, and the needle 26 can poke out the debris remaining in the screen hole to complete the detection.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention.
