Technical Field

[0001] The utility model relates to the technical field of a tool rest of a vacuum rotary cutter, in particular to a tool rest structure for a vacuum rotary cutter. Background Art

[0002] The vacuum rotary cutter is a component module on an RFID laminator, mainly used for cutting long strip-shaped inlays. Generally, the vacuum rotary cutter consists of a tool rest, a roller cutter, and a motor for driving the roller cutter to rotate. The roller cutter is arranged above the vacuum roller on the RFID laminator. As the roller cutter rotates, it is convenient to cut the inlay, which is then adsorbed and conveyed by the vacuum roller. In order to meet the cutting of inlays of different lengths, one or more blades are adaptively installed and fixed on the existing roller cutter. When the roller cutter on the same vacuum rotary cutter needs to cut inlays of different length dimensions, it is necessary to disassemble and replace the roller cutter with different numbers of blades. When replacing the roller cutter, it is necessary to disassemble the machine shell and frame, which takes a long time and has poor efficiency.

[0003] In view of this, it is necessary to design a tool rest structure for a vacuum rotary cutter. This tool rest structure can automatically replace the roller cutter with different numbers of blades according to needs, so as to save manpower and improve the working efficiency of the vacuum rotary cutter.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0025] Please refer to Figure 1-5As shown in the figure, a tool rest structure for a vacuum rotary cutting machine includes a support panel 100. One side of the support panel 100 is fixedly connected with a machine shell 110. One end of the machine shell 110 is provided with an inlay conveying roller group 200, and the other end of the machine shell 110 is provided with a vacuum conveying roller 300. The top of the vacuum conveying roller 300 is provided with a rotary cutting tool rest 400. The outside of the support panel 100 is fixedly connected with a driving mechanism 500 for driving the operation of the rotary cutting tool rest 400. The rotary cutting tool rest 400 includes two symmetrically distributed cross beams 410. Between the two cross beams 410, a plurality of roller cutter bodies 420 are rotatably connected. Between the tops of the two cross beams 410, a U-shaped bracket 430 is fixedly connected. At both ends of the middle part of the U-shaped bracket 430, a lead screw 440 is screwed and a guide shaft 450 is slidably inserted respectively.

[0026] The driving mechanism 500 includes a second motor 510 and a plurality of connecting shafts 520. The output end of the second motor 510 is fixedly connected with a driving gear 540 rotatably connected with the support panel 100. The outside of the connecting shaft 520 is sleeved and fixedly connected with a driven gear 530. Thus, the second motor 510 drives the driving gear 540 to rotate, making the driven gear 530 drive the connecting shaft 520 to rotate. Furthermore, the shaft rod fixedly connected with the connecting shaft 520 drives the roller cutter body 420 to rotate. One end of the connecting shaft 520 is rotatably inserted into the support panel 100. The end of the connecting shaft 520 passing through the support panel 100 is fixedly connected with a shaft rod inserted and fixed with the corresponding roller cutter body 420. The second motor 510 is fixedly connected with the support panel 100. The second motor 510 facilitates driving the rotation of the roller cutter body 420 moving above the vacuum conveying roller 300. Both ends of the guide shaft 450 are fixedly connected with the machine shell 110. Both ends of the lead screw 440 are rotatably connected with the machine shell 110. The outside of the machine shell 110 is fixedly connected with a first motor for driving the rotation of the lead screw 440. Thus, the rotation of the lead screw 440 makes the U-shaped bracket 430 drive a plurality of roller cutter bodies 420 to move to different positions.

[0027] Both ends of the U-shaped bracket 430 are embedded and fixedly connected with electric push rods 431. The output end of the electric push rod 431 is fixedly connected with the corresponding cross beam 410. The output end of the electric push rod 431 drives the cross beam 410 to move up and down, facilitating the roller cutter body 420 to approach the vacuum conveying roller 300 to cut the inlay. A notch is opened on the outside of the roller cutter body 420, and a blade 421 is installed inside the notch. A plurality of screws 4211 are screwed between the blade 421 and the roller cutter body 420. Thus, the blade 421 is detachably installed on the roller cutter body 420. The inlay conveying roller group 200 includes a top roller and a bottom roller both rotatably connected with the machine shell 110. And a cylinder for driving the up and down movement of the top roller is arranged above the top roller. This part is the prior art. The cooperation of the top roller and the bottom roller facilitates the conveying of the inlay. An activity hole 120 is penetrated and opened on the outside of the support panel 100. The activity hole 120 facilitates the horizontal and vertical movement of the connecting shaft 520.

[0028] Working principle: During operation, the inlay is conveyed from between the top roller and the bottom roller of the inlay conveying roller set 200 to between the vacuum conveying roller 300 and the cutter body 420. Then, both the vacuum conveying roller 300 and the cutter body 420 rotate. Among them, the rotation of the vacuum conveying roller 300 can be driven by an external motor, and the rotation of the cutter body 420 is achieved by the second motor 510 driving the driving gear 540 to rotate. The driving gear 540 drives the pre-engaged driven gear 540 to rotate, causing the connecting shaft 520 to drive the shaft rod to rotate, so that the cutter body 420 at the corresponding position rotates to cut the inlay. When it is necessary to replace the cutter body 420, the first motor can drive the lead screw 440 to rotate, causing the U-shaped bracket 430 screwed to the lead screw 440 to drive the two cross beams 410 to move. The movement of the cross beams 410 enables the cutter bodies 420 at different positions to move above the vacuum conveying roller 300. Moreover, different numbers of blades 421 are fixedly installed on the outer sides of the cutter bodies 420 at different positions in an annular and equiangular manner, facilitating moving the cutter body 420 with an appropriate number of blades 421 above the vacuum conveying roller 300 to cut inlays of different sizes as required.
