Technical Field
[0001] The utility model relates to the field related to polymer film processing, in particular to a slitting device for polymer film processing. Background Art
[0002] Polymer functional films are films made of organic polymers (such as PC, PMMA, PET, PVC, TAC, etc.), which usually have one or some specific functions such as protection, optoelectronics, insulation, separation, magnetism, catalytic activity, etc. The manufacturing and application fields of polymer functional films are very wide, covering electronics, optoelectronic displays, transportation, energy, medical care and many other fields. Polymer film materials have excellent optical properties and physical and mechanical properties. By implementing additional functional coatings, the functionality of polymer film materials is further improved and the application value is further increased.
[0003] When processing polymer films, a slitting device is often used to slit the polymer films that have been produced in rolls into finished polymer films of different sizes.
[0004] The slitting device mainly utilizes a slitting blade for slitting. The slitting blade is located at the upper or lower end of the conveying path of the polymer film. Due to the lack of other special structural designs, the polymer film on both sides of the slitting position is prone to curling due to slitting, resulting in a large thickness at the curling position of the polymer film after being rolled, and poor product quality control. Utility Model Content
[0005] The purpose of the utility model is to provide a slitting device for polymer film processing to solve the problem proposed in the above-mentioned background technology that the slitting blade is located at the upper end or lower end of the polymer film conveying path. Due to the lack of other special structural designs, the two sides of the polymer film at the slitting position are prone to curling due to slitting, resulting in a large thickness at the curling position of the polymer film after it is rolled up, and poor product quality control.
[0006] The cam is provided with a plurality of movable parts, and the movable part has two movable parts, and the movable part has two movable parts.
[0007] Preferably, the outer surface of the upper pressure roller is provided with cutting grooves equidistantly from front to back, and a slitting blade is installed in the middle of the outer portion of the limiting sleeve, and the cutting depth of the slitting blade is less than the depth of the cutting grooves.
[0008] Preferably, side fixing rings are fixed at both ends of the limiting sleeve, and the side fixing rings slide along the lower slitting roller. The lower slitting roller and the side fixing rings are both penetrated by through holes and grooves, and the through holes and grooves on the lower slitting roller are equidistantly arranged from front to back. The lower slitting roller and the side fixing rings are fixed by bolts passing through the through holes and grooves.
[0009] Preferably, the fixed vertical plate is provided with a transverse sliding groove running through the front and back, a horizontal limit rod is fixed in the transverse sliding groove at the rear end, a drive motor is installed on one side of the fixed vertical plate at the front end, and a bidirectional threaded rod is connected to the inside of the transverse sliding groove at the front end along the output shaft end of the drive motor.
[0010] Preferably, transverse sliding blocks are slidably connected on both sides of the transverse sliding groove, the transverse sliding block at the rear end is slidably connected to the horizontal limit rod, the transverse sliding block at the front end is threadedly connected to the bidirectional threaded rod, and an adjusting roller is rotatably connected between the two transverse sliding blocks on each side through a bearing.
[0011] Preferably, a supporting horizontal plate is welded and fixed in the middle of the lower ends between the two fixed vertical plates, and supporting legs are welded and fixed on both sides of the outer ends of the fixed vertical plates.
[0012] Preferably, a conveying roller is arranged between the two fixed vertical plates along the outer side of the supporting horizontal plate, and two conveying rollers are arranged one above the other on each side.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. In the utility model, the pressure of the pressure spring inside the vertical sliding groove on the fixed block drives the vertical sliding block to move downward along the vertical limit rod, and the upper pressure roller moves downward synchronously. When the polymer film passes between the upper pressure roller and the lower slitting roller, the polymer film is clamped by the upper pressure roller and the limit sleeve; the polymer film will be cut by the slitting blade during transportation. Since the two ends of the slitting position of the polymer film are clamped by the upper pressure roller and the limit sleeve and have pressure in the up and down directions, the pressure on the polymer film during slitting will not cause curling on both sides of the polymer film, so that the polymer film is still transported outward smoothly, which solves the problem that the slitting blade is located at the upper or lower end of the conveying path of the polymer film. Since there is no other special structural design, the two sides of the polymer film at the slitting position are prone to curling due to slitting, which makes the thickness of the curling position of the polymer film after the conveyed polymer film is rolled up large, and the product quality control is poor.
[0015] 2. In the utility model, the driving motor drives the bidirectional threaded rod to rotate, so that the adjusting rollers on both sides move inward, driving the polymer film inward, so that the polymer film is stretched, and the tension of the polymer film is adjusted without affecting the continuity of transportation, thereby avoiding the situation where some positions are not cut completely due to the polymer film not being tensioned during cutting, thereby improving the cutting quality.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

A conveying roller 10 is arranged between the two fixed vertical plates 1 along the outer side of the supporting horizontal plate 2, and two conveying rollers 10 are arranged on each side.
[0024] A fixed block 11 is fixed in the middle of the upper end of the fixed vertical plate 1, and a vertical sliding groove 12 is opened on the fixed block 11 from front to back, and vertical limiting rods 13 are fixed on both sides of the vertical sliding groove 12. A vertical sliding block 14 is arranged inside the fixed block 11, and the vertical sliding block 14 slides along the vertical limiting rod 13. A telescopic rod 15 is arranged inside the vertical sliding groove 12 along the upper end of the vertical sliding block 14. The telescopic rod 15 consists of an outer sleeve and an intermediate rod that slides within the outer sleeve and extends to the outside. A pressure spring 16 is arranged between the upper end surface of the vertical sliding groove 12 and the vertical sliding block 14 along the outside of the telescopic rod 15. An upper pressure roller 17 is rotatably connected between the two vertical sliding blocks 14 through a bearing, and the outer surface of the upper pressure roller 17 is provided with cutting grooves 1 equidistantly from front to back. 8; A lower slitting roller 19 is rotatably connected along the lower end of the vertical sliding groove 12 between the two fixed blocks 11, and a slitting assembly 21 is arranged outside the lower slitting roller 19, and the slitting assembly 21 includes a limiting sleeve 22, and the limiting sleeve 22 slides along the lower slitting roller 19, and a slitting blade 23 is installed in the middle of the outer side of the limiting sleeve 22, and the cutting depth of the slitting blade 23 is less than the depth of the cutting groove 18, and does not affect the slitting work; side fixing rings 24 are fixed at both ends of the limiting sleeve 22, and the side fixing ring 24 slides along the lower slitting roller 19, and through holes 20 are opened on the lower slitting roller 19 and the side fixing ring 24, and the through holes 20 on the lower slitting roller 19 are equidistantly arranged from front to back, and the lower slitting roller 19 and the side fixing ring 24 are fixed by bolts 25 passing through the through holes 20.
[0025] Adjust the position of the slitting assembly 21 and increase the number of slitting assemblies 21 according to the slitting width requirements. After releasing the bolts 25, lift the upper pressure roller 17 upwards. The slitting assembly 21 can move freely outside the lower slitting roller 19. When reaching the target position, the through hole groove 20 on the lower slitting roller 19 is aligned with the through hole groove 20 on the side fixing ring 24, and then fixed with the bolts 25.
[0026] Due to the adjustability of the position of the slitting component 21, when the slitting component 21 is fixed at different positions outside the lower slitting roller 19, a cutting groove 18 is opened outside the lower slitting roller 19 at the plane position where the slitting blade 23 is located, so that the cutting groove 18 always matches the position of the slitting blade 23.
[0027] Furthermore, a transverse sliding groove 4 is opened on the fixed vertical plate 1 from front to back, a horizontal limit rod 5 is fixed in the rear end transverse sliding groove 4, a driving motor 6 is installed on one side of the front end fixed vertical plate 1, and a bidirectional threaded rod 7 is connected to the output shaft end of the driving motor 6 inside the front end transverse sliding groove 4; transverse sliding blocks 8 are slidably connected on both sides of the transverse sliding groove 4, the rear end transverse sliding block 8 is slidably connected to the horizontal limit rod 5, the front end transverse sliding block 8 is threadedly connected to the bidirectional threaded rod 7, and an adjusting roller 9 is rotatably connected between the two transverse sliding blocks 8 on each side through a bearing.

[0029] Working principle: The polymer film is pulled through between two conveying rollers 10 on one side, along the bottom of the adjusting roller 9 on one side to between the upper pressure roller 17 and the lower slitting roller 19, and then along the bottom of the adjusting roller 9 on the other side to between the two conveying rollers 10 on the other side, and then pulled out and reeled by the rotation of the rollers of multiple reeling devices.
[0030] Due to the pressure of the pressure spring 16, the vertical sliding block 14 will move downward along the vertical limiting rod 13, and the upper pressure roller 17 will move downward synchronously. When the polymer film passes between the upper pressure roller 17 and the lower slitting roller 19, the polymer film is clamped by the upper pressure roller 17 and the limiting sleeve 22; the polymer film will be cut by the slitting blade 23 during transportation. Since the two ends of the polymer film slitting position are clamped by the upper pressure roller 17 and the limiting sleeve 22 and there is pressure in the upper and lower directions, the polymer film is still transported outward smoothly.
