[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0022] like Figures 1 to 4 As shown, a slitting device for processing protective film includes a worktable 2, the worktable 2 including a wide film roll 3, a slitting mechanism and an edge blowing mechanism, and the wide film roll 3 having film material 8 on it;
[0023] The slitting mechanism includes a slitting box 41, a slitting frame 42, a cutting blade 43, and a conveying base 44. The conveying base 44 is mounted on the workbench 2 and has several first conveying rollers 441. Limiting conveying frames 442 are installed on both sides of the conveying base 44, and each limiting conveying frame 442 has a protruding plate 443. Several second conveying rollers 444 are arranged on the protruding plate 443. The slitting box 41 is mounted on one side wall of the workbench 2. The slitting frame 42 is mounted on the slitting box 41, and a slitting seat 45 that can move forward or backward is mounted on the slitting frame 42. Several first lifting motors 46 are fixed on the slitting seat 45. A cutting blade seat 47 is mounted on the lifting rod of each of the first lifting motors 46. A dividing block 471 is installed at the center of the cutting blade seat 47, and first guide rails 472 are arranged on both sides of the cutting blade seat 47 with the dividing block 471 as the center. A cutter 43 is slidably mounted on the first guide rail 472; the edge blowing mechanism includes a third conveying roller 51 and an edge blowing frame 52. Telescopic rods 21 are located on both sides of the workbench 2, and edge blowing frames 52 are mounted on the telescopic rods 21. Edge blowing assemblies are symmetrically arranged on the edge blowing frames 52. The edge blowing assemblies include a blower 531, a connecting cylinder 532, air supply pipes 533 located on both sides of the connecting cylinder 532, a pressure film seat 534, and an air outlet pipe 535. The blower 531 is mounted on the edge blowing frame 52, and the connecting cylinder 532 is mounted under the edge blowing frame 52. Each blower 531 is connected to an air supply pipe 533. The connecting cylinder 532 and the two air supply pipes 533 are connected to the film pressing seat 534. Air outlet pipes 535 are installed on both sides of the film pressing seat 534. The two air supply pipes 533 are inserted into the film pressing seat 534 and connected to the air outlet pipes 535. Each air outlet pipe 535 is aligned with the edge of one side of the film material 8.
[0024] In this utility model, the cutting blade 43 and the blower 531 are existing technologies.
[0025] With the above structure, a slitting device is set up, and push rod motors are also set on both sides of the cutter seat 47 and the partition block 471 of the slitting frame 42. The position of a single cutter 43 can be adjusted to the left or right as needed. Overall, the distance between the two cutters 43 can be adjusted by fine adjustment, which is beneficial for slitting the width according to the required film material 8, making it more practical. After the slitting mechanism is used for slitting, an edge blowing mechanism is added. The height of the edge blowing assembly is adjusted by the edge blowing frame 52. At the same time, the blower 531 operates, and the air is blown from the blower 531 through the air pipe 533 and the film pressing seat 53. Inside the 4th layer, the air is blown out to both sides by the two air outlets 535 on the left and right sides of the pressure plate 534. The blowing direction of the air outlets 535 is designed to be perpendicular to the conveying direction of the film material 8. When the film material 8 passes through the edge blowing mechanism, the air blown out of the air outlets 535 can flatten the curled edges of the film material 8 caused by the cutting process. Since the relatively soft film material 8 retains a certain degree of softness during the cutting process, it can be flattened by blowing air, without causing the curling to become more severe due to wind speed and air pressure. This helps to prevent the soft protective film from curling, improves the winding quality, enhances practicality, and greatly reduces processing costs.
[0026] Specifically, if Figures 1 to 4 As shown, the worktable 2 also includes a narrow-width film roll 22, which has a first take-up roll section 221, a second take-up roll section 222 and a third take-up roll section 223. The second take-up roll section 222 is located between the first take-up roll section 221 and the third take-up roll section 223, and the diameter of the second take-up roll section 222 is smaller than the diameters of the first take-up roll section 221 and the third take-up roll section 223.
[0027] By adopting the above structure, by setting two first winding rollers 221 and third winding rollers 223 to wind up the two narrow film materials 8, it is beneficial to automatically wind up the film material 8. Furthermore, by adding a second winding roller 222 between the first winding rollers 221 and the third winding rollers 223, the remaining section of film material 8 can also be wound up and collected, which is beneficial for recycling, making winding more convenient and reducing waste.
[0028] like Figures 1 to 4 As shown, the conveying base 44 also has a first groove 61. A first mounting plate 62 is symmetrically arranged on the groove wall of the first groove 61 on the conveying base 44. A plurality of hydraulic cylinders 63 are mounted on the first mounting plate 62. A cutting plate 64 is mounted on the piston rod of the hydraulic cylinder 63. The cutting plate 64 has a cutting groove 65.
[0029] With the above structure, a slitting plate 64 is provided below the cutter 43, and this slitting plate 64 is detachably mounted on the piston rod of the hydraulic cylinder 63. It can be replaced and adjusted according to the required width of the film material 8 to be slit. At the same time, by providing the slitting groove 65, it is beneficial to reduce the damage to the slitting blade, extend the service life of the device, and make it more practical.
[0030] like Figures 1 to 4 As shown, the first conveying roller 441 abuts against the lower surface of the film material 8 to convey the film material 8, and the second conveying roller 444 abuts against the upper surface of the film material 8 to convey the film material 8.
[0031] With the above structure, the membrane material 8 is conveyed by the first conveying roller 441 and the second conveying roller 444, which is conducive to automatic conveying and has a good conveying effect.
[0032] like Figures 1 to 4 As shown, the membrane material 8 passes sequentially from the wide-width membrane roll 3 through the slitting mechanism and the edge blowing mechanism, and is then wound up by the narrow-width membrane roll 22.
[0033] The above structure, which performs slitting and edge blowing in this sequence, helps prevent the softer protective film from curling at the edges, improves winding quality, enhances practicality, and significantly reduces processing costs.
[0034] like Figures 1 to 4 As shown, a control panel 71 is also installed on one side of the slitting box 41. The edge cutting mechanism and edge blowing mechanism on the worktable 2 can be controlled and adjusted through the control panel 71, resulting in a high degree of automation.
[0035] like Figures 1 to 4 As shown, the bottom of the pressure plate holder 534 has a protective pad 72. By setting the protective pad 72, the protective pad 72 can limit the passage of the membrane material 8 without affecting it, which is beneficial to better protect the membrane material 8 during processing.
