[0023] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0024] like Figure 1As shown, the PCB copper foil and PP fixed-size cutting machine provided by the present invention includes a machine platform 100, a coil rack 200, a pressing assembly 300, a pulling assembly 400 and a cutting assembly 500. The coil rack 200 is configured to place the coil, the pressing assembly 300 is installed on the machine platform 100, the pressing assembly 300 has a clamping end, the pulling assembly 400 is arranged at a position on the side of the pressing assembly 300 away from the coil rack 200, the pulling assembly 400 is slidably connected to the machine platform 100 along the connecting direction of the coil rack 200 and the pressing assembly 300, the pulling assembly 400 has a pulling end for connecting the head end of the coil, the cutting assembly 500 is installed on the machine platform 100 and is arranged at a position between the pressing assembly 300 and the pulling assembly 400, and the cutting assembly 500 has a cutting end.

[0025] During implementation, the PCB copper foil or PP coil is placed on the coil rack 200, so that the head end of the coil passes through the clamping end of the pressing component 300, and the pulling end of the pulling component 400 is connected to the head end of the coil. As the pulling component 400 slides on the machine 100, the sliding distance is the length of the coil unwinding, which is easy to control. At the same time, the entire pulling process is realized by machinery to avoid wrinkles in the coil. Finally, the clamping end of the pressing component 300 fixes the coil, and the cutting end of the cutting component 500 cuts the coil below it, thereby realizing the process of cutting the coil.

[0026] The machine 100 in this embodiment is a structure that supports the pressing assembly 300, the pulling assembly 400 and the cutting assembly 500. The top of the machine 100 is a flat surface, which facilitates the unwinding portion of the coil to be laid thereon.

[0027] The roll holder 200 in this embodiment comprises two brackets and a roller. The roller's ends are rotatably and detachably connected to the two brackets. The roll is placed onto the roller, and as the roller rotates, the roll is unwound. It is understood that the brackets may be triangular or frame-shaped, and this is not a limitation.

[0028] In this embodiment, the pressing assembly 300 is a structure for fixing the unwinding portion of the coil, which is installed on the machine 100. The pressing assembly 300 has a clamping end, which can clamp the unwinding portion of the loose coil.

[0029] like Figure 2As shown, in one embodiment, the pressing assembly 300 includes two first brackets 310, a fixed plate 320, two first driving members 330 and a movable plate 340. The two first brackets 310 are fixedly arranged on both sides of the machine 100, the fixed plate 320 is arranged across the machine 100 and the two ends are fixedly connected to the two first brackets 310 respectively. The two first driving members 330 are respectively installed on the two first brackets 310 and the output ends are respectively fixedly connected to the two sides of the movable plate 340 to drive the movable plate 340 to move in a direction close to or away from the fixed plate 320. A clamping gap parallel to the table surface of the machine 100 is formed between the fixed plate 320 and the movable plate 340.

[0030] In this embodiment, when it is necessary to clamp the unwinding part of the coil, the two first driving members 330 drive the movable plate 340 to move in a direction close to the fixed plate 320 until the fixed plate 320 and the movable plate 340 clamp the unwinding part of the coil passing through their clamping gap; when it is necessary to loosen the unwinding part of the coil, the two first driving members 330 drive the movable plate 340 to move in a direction away from the fixed plate 320, and the clamping gap is greater than the thickness of the unwinding part of the coil.

[0031] It is understandable that the first driving member 330 can be implemented by using a structure such as a pneumatic cylinder or an oil cylinder.

[0032] The pulling assembly 400 in this embodiment is a structure that drives the head end of the coil to move. The pulling assembly 400 is arranged at a position on the side of the pressing assembly 300 away from the coil rack 200. The pulling assembly 400 is slidably connected to the machine 100 along the connecting direction of the coil rack 200 and the pressing assembly 300. The pulling assembly 400 has a pulling end for connecting the head end of the coil.

[0033] like Figure 3 As shown, in one embodiment, the pulling assembly 400 includes a cross bar 410, a plurality of pulling heads 420 and a second driving member 430. The cross bar 410 is arranged across the machine 100 and is connected to the second driving member 430. The output end of the second driving member 430 is connected to the machine 100 to drive the cross bar 410 to move along the length direction of the machine 100. The plurality of pulling heads 420 are arranged in sequence along the length direction of the cross bar 410 and are arranged on the side of the cross bar 410 close to the pressing assembly 300. The pulling head 420 is the pulling end.

[0034] When the plurality of pulling heads 420 are connected to the head end of the coil, the second driving member 430 drives the plurality of pulling heads 420 on the cross bar 410 to move, that is, to pull the coil for unwinding operation. The distance the pulling heads 420 move is the length of the unwinding coil.

[0035] like Figure 4As shown, in one embodiment, the pulling head 420 includes a second bracket 421, a cylinder 422, a pulling base plate 423 and a pressure block 424. The second bracket 421 is fixedly connected to the side of the cross bar 410 close to the pressing assembly 300. The cylinder 422 and the pulling base plate 423 are arranged in sequence on the second bracket 421 in a vertical downward direction. The output end of the cylinder 422 is directed to the pulling base plate 423 and is connected to the pressure block 424. A pulling gap for clamping the head end of the coil is formed between the pressure block 424 and the pulling base plate 423.

[0036] In one embodiment, the second driving member 430 includes a guide rail 431, a slider 432, a motor 433, a gear and a rack 434. The guide rail 431 and the rack 434 are arranged in parallel and are fixedly arranged on the side wall of the machine 100. The slider 432 is slidably connected to the guide rail 431, the motor 433 is installed on the slider 432, the output end of the motor 433 is connected to the gear, the gear is meshed with the rack 434, and the slider 432 is fixedly connected to the cross bar 410.

[0037] There are two second driving members 430 , which are disposed oppositely on two sides of the machine platform 100 . Both ends of the crossbar 410 are fixedly connected to the two sliders 432 .

[0038] It can be understood that in order to improve the sliding stability of the cross bar 410, the second driving member 430 also includes a connecting rod 435 connecting the two sliders 432. At the same time, the second driving member 430 also includes a starting switch 436 installed on the slider 432 and electrically connected to the motor 433, which is convenient for controlling the opening and closing of the motor 433. In order to prevent the slider 432 from detaching from the guide rail 431, the two ends of the guide rail 431 are also fixedly connected to limit blocks.

[0039] like Figure 5 As shown, in order to know the length of the unrolled material, that is, the sliding distance of the slider 432 , in one embodiment, the cutting machine further includes a scale 440 installed on the side wall of the machine platform 100 and facing the guide rail 431 .

[0040] The cutting assembly 500 in this embodiment is installed on the machine 100 and disposed between the pressing assembly 300 and the pulling assembly 400 . The cutting assembly 500 has a cutting end.

[0041] like Figure 6 As shown, in one embodiment, the cutting assembly 500 includes a cutting base plate 510, a beam 520, a third driving member 530 and a cutter 540. The cutting base plate 510 is fixedly arranged on the machine 100, the beam 520 is arranged across the cutting base plate 510, and the third driving member 530 is installed at the bottom of the beam 520 and the output end is connected to the cutter 540, which is used to drive the cutter 540 to move in the vertical direction.

[0042] The length direction of the cutter 540 is perpendicular to the sliding direction of the pulling assembly 400 , and the cross section of the cutter 540 along its length direction is a tapered structure that gradually expands vertically upward.

[0043] The cutting base plate 510 is provided with a V-shaped groove 511 adapted to the tip of the cutting blade 540 .

[0044] It is understandable that the third driving member 530 can be implemented by using a structure such as a pneumatic cylinder or an oil cylinder.

[0045] Compared with the existing technology: the PCB copper foil or PP coil is placed on the coil rack 200, the head end of the coil passes through the clamping end of the pressing component 300, and the pulling end of the pulling component 400 is connected to the head end of the coil. As the pulling component 400 slides on the machine 100, the sliding distance is the length of the coil unwinding, which is easy to control. At the same time, the entire pulling process is realized by machinery to avoid wrinkles in the coil. Finally, the clamping end of the pressing component 300 fixes the coil, and the cutting end of the cutting component 500 cuts the coil below it, thereby realizing the process of cutting the coil.

[0046] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
