[0025] In this embodiment, the cutting mechanism 300 is a structure for performing adjustable and stable cutting of the protective film roll.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the cutting mechanism 300 includes two support columns 301 fixed to the top of the processing table 1, a fixed box 302 fixed between the tops of the two support columns 301, a bidirectional lead screw 303 rotatably connected to the inner side of the fixed box 302 through a bearing, two moving blocks 304 threadedly connected to the outer side of the bidirectional lead screw 303, a first driving mechanism 305 fixedly installed on the back side of the fixed box 302, a connecting plate 306 fixed to the bottom of the moving block 304, a linear driving mechanism 307 fixedly installed on the bottom of the connecting plate 306, and a cutting component installed at the bottom of the linear driving mechanism 307.

[0027] It should be noted that the output shaft of the first driving mechanism 305 passes through the back side of the fixed box 302 and is fixedly connected to one end of the back side of the bidirectional screw rod 303, so that the first driving mechanism 305 can drive the bidirectional screw rod 303 to rotate, and a straight hole for the two moving blocks 304 to slide is provided at the bottom of the fixed box 302, and a positioning rod is fixedly connected to the inner side of the straight hole, the front end of which passes through the two moving blocks 304 in sequence, so that the moving blocks 304 can be driven by the bidirectional screw rod 303 to move closer to or away from each other under the positioning action of the positioning rod.

[0028] In addition, the first driving mechanism 305 may be a servo motor, and the linear driving mechanism 307 may be a device with linear driving capability such as a cylinder or an electric telescopic rod.

[0029] In this embodiment, the cutting assembly is a structure used to cut the protective film roll and enable the cut edge to be normally conveyed in a tensioned state.

[0030] like Figure 1 , Figure 3 and Figure 4 As shown, the cutting assembly protects a mounting block 308 fixedly mounted on the end of the output shaft of the linear drive mechanism 307, a cutting tool 309 detachably mounted on the outside of the mounting block 308, an extension block 310 fixed on the left side of the mounting block 308, a rotating hole 311 opened at the top of the extension block 310, a round rod 312 rotatably connected to the inner side of the rotating hole 311 through a bearing, a mounting rod 313 fixed on the outside of the round rod 312, a roller 314 rotatably connected to the other end of the mounting rod 313, a second driving mechanism 315 fixedly mounted on the outside of the mounting rod 313 and capable of driving the roller 314 to rotate, a pushing plate 316 fixed on the top of the outside of the mounting rod 313, an arc rod 317 fixed on the right side of the pushing plate 316, an elastic member 318 fixed between the right side of the pushing plate 316 and the top of the corresponding extension block 310, and a limiting member 319 fixed to the other end of the arc rod 317.

[0031] It should be noted that the left side of the rotating hole 311 is open so that the mounting rod 313 can rotate normally. An arc hole is provided on the top of the extension block 310 for the arc rod 317 to be plugged in and move. The limiter 319 is located below the extension block 310. The elastic member 318 is located on the outside of the corresponding arc rod 317. The elastic member 318 can be a spring, so that the push plate 316 can push the arc rod 317 to move on the inside of the arc hole, thereby making the elastic member 318 stably compressed.

[0032] In addition, two connecting plates are fixed to the end of the mounting rod 313, and a driving shaft is rotatably connected between the opposite sides of the two connecting plates through bearings. The roller 314 is fixed to the outside of the driving shaft, and the second driving mechanism 315 is fixedly installed on the front side of the front connecting plate, and the output shaft of the second driving mechanism 315 passes through the front side of the front connecting plate and is fixedly connected to the front end of the driving shaft, so that the second driving mechanism 315 can drive the driving shaft to rotate, thereby rotating the roller 314. The second driving mechanism 315 is a small servo motor, and the rotation rate of the second driving mechanism 315 needs to match the protective film winding mechanism, wherein the protective film winding mechanism is a structure for winding the protective film coil, which belongs to the rear-end equipment of the device and is used to drive the protective film coil to move, so it will not be described in detail in the text.

[0033] In this embodiment, the edge component 200 is a structure used to limit the edge of the protective film coil.

[0034] like Figure 1 and Figure 2As shown, the edge assembly 200 includes two fixed plates 201 fixed to the top of the processing table 1, six slides 202 respectively fixed to the opposite sides of the two fixed plates 201, a sliding rod 203 slidably connected to the inner side of the slide 202, a baffle 204 fixed between the ends of the corresponding three sliding rods 203, and a hand screw 205 threadedly connected to the top of the slide 202.

[0035] It should be noted that the front of the fixed plate 201 is provided with through holes corresponding to the positions of the three slide cylinders 202 , and the interior of the through holes is connected to the interior of the corresponding slide cylinder 202 , so that the sliding rod 203 can slide between the through holes and the interior of the slide cylinder 202 .

[0036] In addition, the two baffles 204 are located between the opposite sides of the two fixed plates 201, so that the baffles 204 can play a certain limiting role on the edge of the protective film roll, and the end of the hand-turned screw 205 is in contact with the outer side of the corresponding sliding rod 203, so that the hand-turned screw 205 can play a certain squeezing and limiting role on the outer side of the sliding rod 203.

[0037] The working principle of the above embodiment is:

[0038] When cutting the protective film coil, the protective film coil is laid on the top of the processing table 1 through the right side of the processing table 1, and the first driving mechanism 305 is started to rotate the bidirectional screw rod 303, so that the two moving blocks 304 can move closer to each other or away from each other, so that the positions of the two cutting tools 309 can be adaptively adjusted according to the length of the cutting edge. After the adjustment is completed, the hand-screw 205 is loosened, and the baffle plate 204 is pushed to fit the edge of the protective film coil. The hand-screw 205 is tightened to position the sliding rod 203, so that the two baffle plates 204 can respectively play a role in fitting and limiting the two sides of the protective film coil. The linear driving mechanism 307 is started to make the bottom end of the cutting tool 309 fit the top of the protective film coil. At the same time, the roller 314 drives the mounting rod 313 to rotate, so that The pushing plate 316 can push the elastic member 318 to be compressed, and the edge of the protective film coil can be pressed and limited by the pushing plate 316, the mounting rod 313 and the roller 314 under the elastic recovery action of the elastic member 318, so that it can still be tensioned after cutting, which is convenient for the cutting work. The winding mechanism is started so that the protective film coil can be transported to the left side, so that it can be cut by the cutting tool 309 during the movement of the protective film coil, so that the edge part can be separated from the main body part, and the second driving mechanism 315 is started to drive the roller 314 to rotate, so that the cut part of the edge of the protective film coil can be driven by the roller 314 to move, so that the cut part can enter the inside of the collection box 5 through the discharge hole 4 on the same side and be collected, and the edge cutting of the protective film coil can be completed smoothly and stably.

[0039] Compared with the prior art, the protective film roll cutting edge protection device can synchronously adjust the length of the cutting edge through the coordinated use between the edge component 200 and the cutting mechanism 300 on the top of the processing table 1, and can allow the material cut by the edge to be discharged smoothly, so that the edge cutting work of the roll material can be carried out stably under the adjustable protective structure, thereby improving the overall adaptability of the device, thereby greatly improving the practicality of the roll material cutting edge protection device, and solving the problem that the existing roll material cutting edge protection device cannot be easily adjusted, resulting in its insufficient adaptability.
