Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0022] The utility model discloses a slitting machine for cast film, which is mainly used in traditional slitting machines for cast film. When a double-station winder is used to wind the film, the film will rotate during the winding process, and the winding position will change accordingly. The fixed position of the cutting knife is not conducive to cutting the film, which affects the winding scene of the film.

[0023] Reference Figure 1 and Figure 2 A slitting machine for cast film, comprising a frame 1, a film body 2 and a double-station winder 3 provided on the frame 1, and further comprising:

[0024] Cutting mechanism: The cutting mechanism is located on the inner wall of the frame 1;

[0025] A first mounting groove 4 is provided on the inner walls on both sides of the frame 1, and a first electric telescopic rod 8 is fixedly installed on the bottom inner wall of the first mounting groove 4. One end of the piston rod of the first electric telescopic rod 8 is fixedly connected to a connecting block 9, and the outer walls on the opposite side of the two connecting blocks 9 are provided with the same connecting roller 6. Both sides of the circumferential outer wall of the connecting roller 6 are sleeved with an adaptation block 10, and the outer walls on the opposite side of the two adaptation blocks 10 are fixedly connected to the same connecting rod 11. The outer walls on both sides of the connecting rod 11 are provided with a first electric slide rail, and a first slider 12 is slidably connected to the inner wall of the first electric slide rail. The two first sliders 12 are fixedly connected to the same first ring 13 on the outer wall of the separated side, and a cutting knife 14 is provided on the outer wall of one side of the first ring 13. The circumferential outer wall of the cutting knife 14 is provided with a return spring 15 and a limit ring.

[0026] During the specific working process, after the film body 2 is rolled up, the film body 2 needs to be cut. The first electric telescopic rod 8 is used to drive the connecting block 9 to move upward or downward, so as to adapt to the winding position of the double-station winder 3. When cutting, the first slider 12 slides in the first electric slide rail, driving the cutting knife 14 on the first ring 13 to slide from one side of the film body 2 to the other side for cutting. At the same time, under the action of the reset spring 15, the cutting knife 14 is aligned with the film body 2 for cutting, so that the film body 2 is cut and then rolled up.

[0027] Among them, the reset spring 15 is located between the limit ring and the first ring 13, and the cutting direction of the cutting knife 14 is flush with the connecting roller 6. In this way, the cutting knife 14 is aligned with the connecting roller 6, and the position of the cutting knife 14 is changed by the squeezing and resetting of the reset spring 15, so that the cutting knife 14 is aligned with the film body 2 for cutting, which is better.

[0028] Among them, the cutting knife 14 and the connecting roller 6 are used in conjunction with the film body 2. In this way, the film body 2 is wrapped around the connecting roller 6, so that the film body 2 is located between the cutting knife 14 and the connecting roller 6. When the film body 2 needs to be cut during winding, the cutting knife 14 cuts the film body 2, and the cooperation effect is good.

[0029] It should be noted that: the position of the cutting knife 14 is located on one side of the connecting roller 6 in the initial state and does not contact the film body 2. When cutting is required, the first electric slide rail works to move the position of the cutting knife 14. At the same time, under the action of the reset spring 15, the cutting knife 14 is brought into contact with the film body 2 for cutting.

[0030] Reference Figure 1 and Figure 3 In a preferred embodiment, the slitting mechanism includes a second mounting groove 5 opened on the inner walls on both sides of the frame 1, and a second electric telescopic rod 16 is fixedly installed on the bottom inner wall of the second mounting groove 5, one end of the piston rod of the second electric telescopic rod 16 is fixedly connected to a mounting block, a fixing rod is fixedly connected to the top outer wall of the mounting block, and the top of the fixing rod is fixedly connected to the fixing block. The same transfer roller 7 is provided on the outer walls of the opposite sides of the two fixed blocks, and the same mounting rod 17 is fixedly connected to the outer walls of the opposite sides of the two mounting blocks. Second electric slide rails are provided on the outer walls of both sides of the mounting rod 17, and a second slider 18 is slidably connected to the inner wall of the second electric slide rail. The same second ring 19 is fixedly connected to the outer surface of the separated side of the two second sliders 18, and a double slitting head 20 is provided on the top outer wall of the second ring 19.

[0031] Specifically, according to the winding position, it is necessary to cut in the middle position of the film body 2. In order to adapt to the rotation during winding, the second electric telescopic rod 16 is used to drive the mounting block and the fixed block to move adaptively, thereby moving and adapting the position of the transfer roller 7 and the mounting rod 17. Then, the second slider 18 is driven to move by the second electric slide rail, so that the slitting double blade head 20 on the second ring 19 cuts the film body 2, and the cut waste falls from the middle position, and the cut film body 2 is wound up.

[0032] Among them, the double slitting heads 20 and the transfer roller 7 are used in conjunction with the film body 2 respectively. In this way, the film body 2 is transferred by the transfer roller 7. During the transfer process, the double slitting heads 20 simultaneously cut the film body 2 to adapt to the winding position, which is more convenient for winding.

[0033] Reference Figure 1 and Figure 4 In a preferred embodiment, a motor 23 is provided on the outer wall of one side of the frame 1, and one end of the output shaft of the motor 23 is connected to the double-station winder 3. The double-station winder 3 is respectively provided with two rotating rollers 21, a fixed shaft and two connecting shafts, and two winding rollers 22 are provided on the circumferential outer wall of the connecting shaft. The rotating rollers 21 and the winding rollers 22 are staggered.

[0034] Specifically, when the double-station winder 3 is working, the motor 23 is started, and the motor 23 drives the double-station winder 3 to rotate. The double-station winder 3 can realize automatic winding. The two winding rollers 22 set on the connecting shaft in this scheme can realize the simultaneous winding of four winding rollers 22 at the double station. The different lengths of the winding rollers 22 can be adapted and cut by moving the position of the double slitting head 20.

[0035] Among them, the film body 2 and the slitting double blade head 20 are used in conjunction with the winding roller 22. In this way, the film body 2 is wound by the winding roller 22, and the film body 2 can be cut according to the length of the winding roller 22 by using the position of the adaptive slitting double blade head 20. The film body 2 of the corresponding length is wound by the winding roller 22 for subsequent use.

[0036] Working principle: When in use, the film body 2 is transferred from the connecting roller 6 to the transfer roller 7, and then is reeled by the winding roller 22. The film body 2 after reeling is cut at the connecting roller 6, and the film body 2 is adapted and cut according to the length of the reeling roller 22 at the transfer roller 7. When the film body 2 needs to be cut, the first electric telescopic rod 8 is used to drive the connecting block 9 to move upward or downward, thereby adapting to the reeling position of the double-station reeling machine 3. When cutting, the first slider 12 slides in the first electric slide rail, driving the cutting knife 14 on the first ring 13 from one side of the film body 2 Slide to the other side for cutting, and at the same time, under the action of the return spring 15, the cutting knife 14 is aligned with the film body 2 for cutting. According to the length of the winding roller 22, while the transfer roller 7 transfers the film body 2, in order to adapt to the rotation during winding, the second electric telescopic rod 16 is used to move and adapt the positions of the transfer roller 7 and the mounting rod 17, and then the second slider 18 is driven to move by the second electric slide rail, so that the slitting double blade head 20 on the second ring 19 cuts the film body 2. After slitting, it is wound by the winding roller 22. The double-station winder 3 realizes automatic winding, and the winding efficiency is higher.
