[0002] A film slitting machine is a mechanical device that cuts film into several narrower widths. The device consists of an unwinding mechanism, a cutting mechanism, and a rewinding mechanism. The cutting is carried out sequentially by rollers of each function, and the cut film reaches the required width. When packaging explosives, antistatic film is required for wrapping.

[0003] Existing film slitting machines are not fully functional and may cause inconvenience during use. For example, the cutting blades of most devices are not adjustable in angle and width, resulting in large measurement errors of the film during slitting. Most existing film slitting machines are also large in size and lack a moving device, making movement time-consuming and laborious, and the devices are not very flexible. Furthermore, most existing film slitting machines are not very stable and are prone to shaking.

[0004] As disclosed in CN213230863U, a slitting device for antistatic film processing is equipped with a first, second, and third electric telescopic support rod, an angle adjuster, a rotary knob, a rotary groove, a measuring plate, a slitting blade, a fixing nut, a fourth electric telescopic support rod, and a fifth electric telescopic support rod. During use, the parts interact and cooperate with each other, facilitating height adjustment, increasing the usable range, enabling slitting of film rolls of different sizes, adjusting the angle and distance of the slitting blade, and improving the accuracy of film slitting. Furthermore, the inclusion of casters, mounting grooves, electric telescopic push rods, and suction cups allows for good mobility and time-saving, labor-saving movement, and improved stability of the device.

[0005] However, the device cannot tension the antistatic film when slitting it, resulting in wrinkles caused by film relaxation, which affects the slitting quality.

[0006] Therefore, we urgently need to provide a slitting device for antistatic film used in explosive packaging. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0027] Due to the limitations of current technology, the antistatic film cannot be tensioned during slitting, resulting in wrinkles caused by film relaxation and affecting slitting quality. Please refer to [link / reference needed]. Figures 1-5 This embodiment provides a slitting device for antistatic film used in explosive packaging, which can avoid wrinkles caused by film relaxation and improve slitting quality. The slitting device for antistatic film used in explosive packaging includes a base plate 1, a support plate 2, a motor 3, a rotating shaft 4, and a take-up roller 5. The support plate 2 is fixedly installed at the front and rear ends of the top right side of the base plate 1. The motor 3 is fixedly installed on the upper front of the support plate 2. The rotating shaft 4 is fixedly installed at the output end of the motor 3. The take-up roller 5 is installed on the outside of the rotating shaft 4. The slitting device is provided on the top of the base plate 1. The slitting device includes a tensioning mechanism, a slitting mechanism, and a disassembly / assembly mechanism.

[0028] The tensioning mechanism is located at the top of the base plate 1, the cutting mechanism is located at the top of the base plate 1, and the disassembly and assembly mechanism is located above the base plate 1.

[0029] The tensioning mechanism includes a vertical plate 601, a lower pressure roller 602, a threaded rod 603, an adjusting block 604, an upper pressure roller 605, and a slider 606. The vertical plate 601 is fixedly installed at the front and rear ends of the top left side of the base plate 1. A rectangular through groove is opened at the upper end of the interior of the vertical plate 601. The adjusting block 604 is installed inside the rectangular through groove, and a sliding groove is opened on the inner wall of the rectangular through groove. The slider 606 is slidably connected to the inner wall of the sliding groove. By rotating the threaded rod 603, which is threadedly connected to the vertical plate 601, the adjusting block 604 drives the upper pressure roller 605 to move up and down along the sliding groove via the slider 606, thus adjusting the tension of the lower pressure roller 602 and the upper pressure roller 605. The distance between the two vertical plates 601 is adjusted to adjust the tension of the antistatic film. The lower pressure roller 602 is installed on the lower end of the adjacent side of the two vertical plates 601. The threaded rod 603 is threaded to the upper end of the interior of the two vertical plates 601. The adjusting block 604 is rotatably connected to the bottom of the threaded rod 603. The upper pressure roller 605 is installed on the adjacent side of the two adjusting blocks 604. The outer surfaces of the lower pressure roller 602 and the upper pressure roller 605 are made of silicone rubber. The elastic deformation of the silicone rubber can buffer tension fluctuations and prevent the film from being scratched. The slider 606 is fixedly installed on the left and right sides of the adjusting block 604.

[0030] When slitting the antistatic film used for explosive packaging, the distance between adjacent blades 705 needs to be adjusted. Therefore, this device also includes a slitting mechanism, which comprises a mounting plate 701, a connecting rod 702, a movable sleeve 703, a blade holder 704, blades 705, bolts 706, a measuring ruler 707, a pointer 708, and a slitting roller 709. The mounting plate 701 is fixedly installed on the front and rear sides of the top center of the base plate 1. The connecting rod 702 is fixedly installed on the upper end of the adjacent side of the two mounting plates 701. A limiting groove is formed on the outer surface of the connecting rod 702. A protrusion is formed on the inner wall of the movable sleeve 703, and the protrusion is slidably connected to the inner wall of the limiting groove. By pushing the movable sleeve 703 to slide along the limiting groove and rotating the bolt 706, the device can achieve the desired effect. The rod 702 abuts against the movable sleeve 703, thereby enabling the movement and fixation of the blade 705. The movable sleeve 703 is slidably connected to the outside of the connecting rod 702. The blade holder 704 is fixedly installed on the outside of the movable sleeve 703. The blade 705 is installed inside the blade holder 704. The bolt 706 is threadedly connected to the right side inside the movable sleeve 703. The measuring scale 707 is fixedly installed on the adjacent side of the front and rear mounting plates 701 at the upper end of the connecting rod 702. The pointer 708 is fixedly installed on the top of the movable sleeve 703. By cooperating with the measuring scale 707, the distance between two adjacent blades 705 is measured to improve the cutting accuracy. The cutting roller 709 is installed at the lower end of the adjacent side of the front and rear mounting plates 701. Example

[0031] Based on Example 1, please refer to Figures 1-5As the blade 705 wears out after prolonged use, it needs to be replaced. Therefore, this device is also equipped with a disassembly and assembly mechanism, which includes a mounting rod 801, a fixing rod 802, and a pressure plate 803. The mounting rod 801 is fixedly installed on the inner wall of the tool holder 704, and the fixing rod 802 is threadedly connected to the inner wall of the mounting rod 801. The pressure plate 803 is fixedly installed on the side of the fixing rod 802 near the mounting rod 801. The fixing rod 802 and the pressure plate 803 have connecting holes inside, and the diameter of the connecting holes is equal to that of the mounting rod 801. The blade 705 has an insertion hole inside. The blade 705 is connected to the mounting rod 801, and then the fixing rod 802 is rotated to connect to the tool holder 704, so that the pressure plate 803 is pressed against the blade 705, thereby fixing the blade 705.

[0032] In use, one end of the film is passed between the lower pressure roller 602 and the upper pressure roller 605, then through the upper surface of the slitting roller 709 and wound onto the take-up roller 5. Then, the threaded rod 603 is rotated to connect with the vertical plate 601, causing the adjusting block 604 to move the upper pressure roller 605 up and down along the slide groove via the slider 606, adjusting the distance between the lower and upper pressure rollers 602 and thus the tension of the antistatic film. Next, the movable sleeve 703 is pushed to slide along the connecting rod 702, and the distance between adjacent blades 705 is adjusted using the pointer 708 and the measuring scale 707. Once the movable sleeve 703 has moved to the appropriate position, the bolt 706 is rotated to connect with the connecting rod 702. 02. The movable sleeve 703 is fixed by contact, and then the take-up roller 5 is started to take up the antistatic film. When the antistatic film moves, it is cut by the blade 705. The cut film is wrapped around the take-up roller 5. When the blade 705 needs to be replaced, the fixed rod 802 is screwed to the blade holder 704 by rotating, so that the pressure plate 803 is away from the blade 705. At this time, there is a gap between the mounting rod 801 and the pressure plate 803, so the blade 705 can be removed. Then the new blade 705 is installed on the mounting rod 801, and the fixed rod 802 is used to drive the pressure plate 803 to move and abut against the side of the blade 705 to fix the blade 705, thus completing the replacement of the blade 705.
