Description

Technical Field

[0001] The utility model relates to the technical field of slitting devices, and more specifically, to a non-woven fabric slitting device. Background Technique

[0002] The non-woven fabric is double-woven from 100% polyester fiber, with a soft surface, easy to wipe sensitive surfaces, no fiber shedding during friction, and good water absorption and cleaning efficiency. Currently, during the production process of non-woven fabrics, they are generally slit by a slitting device to cut the non-woven fabrics into non-woven fabric strips of different widths for subsequent processing.

[0003] For example, a fully automatic non-woven fabric slitting and cross-cutting integrated machine disclosed in the patent with the publication number CN214399224U. Although the fully automatic non-woven fabric slitting and cross-cutting integrated machine, through the setting of the adjusting plate, enables the operator not to manually put the cut non-woven fabric into an external container; however, when the fully automatic non-woven fabric slitting and cross-cutting integrated machine is actually used, the distance between multiple cutter heads connected to the lower side of the knife plate cannot be adjusted, resulting in that it can only cut the non-woven fabric into non-woven fabric strips of a fixed width, leading to poor practical applicability, so it needs to be improved.

[0026] To further understand the content of the present utility model, the present utility model will be described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present utility model and not for limiting it.

[0027] The following combines with the attached Figures 1-6 This embodiment will be further described in detail below.

[0028] Combined with Figures 1-6 As shown, a non - woven fabric slitting device in this embodiment includes a base table 100. A bracket 110 is provided on the base table 100, and a slitting assembly for slitting the non - woven fabric is provided on the bracket 110. The slitting assembly includes a fixed shaft 190 provided on the bracket 110. A plurality of mounting plates 250 are slidably provided on the fixed shaft 190. A slitting knife 230 for slitting the non - woven fabric is provided on the mounting plate 250. One side of the mounting plate 250 is fixed to the fixed shaft 190 through a locking assembly. A lifting assembly for driving the fixed shaft 190 to lift is further provided on the bracket 110, and the fixed shaft 190 is detachably installed on the lifting assembly.

[0029] In actual use of this embodiment, a slitting motor 240 is installed on one side of the lower end of the mounting plate 250 by screws, and the slitting knife 230 is fixedly installed on the output shaft of the slitting motor 240, so that the slitting motor 240 can drive the slitting knife 230 to rotate and cut the dust-free cloth;

[0030] When it is actually used, according to the required width of the dust-free cloth strip, the distance between adjacent mounting plates 250 is adjusted by sliding on the fixed shaft 190, so that the mounting plates 250 can slide and drive the corresponding slitting knives 230 to move, so that the distance between adjacent slitting knives 230 is adjusted, so that the dust-free cloth can be cut into dust-free cloth strips of required width; compared with the existing knife heads that cannot adjust the distance between them, this embodiment adjusts the distance between the slitting knives 230 by sliding the mounting plates 250 on the fixed shaft 190, so that the slitting knives 230 can cut out dust-free cloth strips of different widths, so that the slitting device has better applicability;

[0031] In actual use, a limiting groove 340 is provided on the side wall of the fixed shaft 190 along its length direction, and a through hole for the fixed shaft 190 to pass through is provided on the mounting plate 250. A slider is extended into the limiting groove 340 and slides in the side wall of the through hole. The slider slides in the limiting groove 340 to prevent the mounting plate 250 from rotating along the circumference of the fixed shaft 190, resulting in different cutting point positions of the slitting knife 230, affecting its slitting effect.

[0032] Among them, by setting the locking assembly, when the mounting plate 250 slides to a suitable position, the locking assembly holds the fixing shaft 190 tightly to fix the mounting plate 250, so that the slitting knife 230 thereon can better slit the dust-free cloth;

[0033] During actual use, one end of the dust-free cloth passes through the bracket 110 and is located below the slitting knife 230 and is connected to the existing winding device. The winding device is used to pull the dust-free cloth to be rolled up so that it can pass through the base 100 below the bracket 110. At this time, the fixed shaft 190 is driven downward by the lifting assembly, so that the fixed shaft 190 can drive the mounting plate 250 and the slitting knife 230 to be lifted and lowered, so that the slitting knife 230 abuts against the dust-free cloth. At this time, the slitting motor 240 is started to drive the slitting knife 230 to rotate, and the winding of the winding device is cooperated so that the slitting assembly can better slit the dust-free cloth.

[0034] Combination Figure 1As shown in the figure, in this embodiment, in order to guide the dust-free cloth when it passes through the base 100 so that the cutting knife 230 can cooperate with the dust-free cloth better through lifting, support plates 101 are provided oppositely on both sides of the bracket 110. A fixed roller 111 is rotatably provided between the support plates 101 and above. At a position below the fixed roller 111, a liftable pressure roller 140 is provided through a cylinder 120. The dust-free cloth passes through between the fixed roller 111 and the pressure roller 140. The cylinder 120 pushes the pressure roller 140 upward, so that the two cooperate with each other to guide the dust-free cloth.

[0035] Specifically, fixing blocks are slidably provided on one side of the two support plates 101 close to each other, and the fixing blocks slide along the height direction of the support plates 101. The pressure roller 140 is rotatably connected between the two fixing blocks, and the extending end of the cylinder 120 is fixedly connected to the corresponding fixing block.

[0036] Combined with Figures 2-6 As shown in the figure, in this embodiment, the locking assembly includes a threaded ring 320 fixedly installed on one side wall of the mounting plate 250. A plurality of abutting pieces 330 are provided on the side wall of the threaded ring 320 along its circumference. A sleeve 260 is slidably provided on the fixed shaft 190. The sleeve 260 is threadedly connected to the threaded ring 320 to realize that the plurality of abutting pieces 330 tightly hold the fixed shaft 190.

[0037] When this embodiment is actually used, as Figure 6 shown, the sleeve 260 includes a threaded portion 600 and an extrusion portion 610. The threaded portion 600 is threadedly connected to the outer side wall of the threaded ring 320. An extrusion table surface 620 is provided in the extrusion portion 610 along the circumference of the sleeve 260. As Figure 5 shown, a gap is formed between adjacent abutting pieces 330 to facilitate the deformation of the abutting pieces 330. An inclined surface adapted to the extrusion table surface 620 is provided on the outer side wall of the abutting piece 330 along the circumference of the threaded ring 320. Thus, in actual use, when the threaded portion 600 is threadedly connected to the threaded ring 320, the extrusion portion 610 can be driven to move towards the abutting piece 330, so that the extrusion table surface 620 extrudes the inclined surface, making the abutting piece 330 tightly hold the fixed shaft 190, and further realizing the fixation of the mounting plate 250. At the same time, when the threaded portion 600 is loosened to make the extrusion table surface 620 away from the abutting piece 330, the holding of the abutting piece 330 on the fixed shaft 190 is released, and further the mounting plate 250 can be moved on the fixed shaft 190.

[0038] Combined with Figures 1-2As shown in the figure, in this embodiment, an installation box 160 is provided on the bracket 110, and a chamber is provided inside the installation box 160; the lifting assembly includes threaded rods 170 oppositely arranged on the base 100, the upper ends of the threaded rods 170 extend into the chamber, lifting blocks 180 are provided at both ends of the fixed shaft 190, the threaded rods 170 penetrate through the corresponding lifting blocks 180, and the synchronous rotation of the threaded rods 170 is used to realize the synchronous lifting of the lifting blocks 180 on the threaded rods 170. A sprocket 220 is provided at one end of the threaded rod 170 extending into the chamber, and the sprockets 220 are connected by a chain 210 to realize the synchronous rotation of the threaded rods 170.

[0039] In actual use of this embodiment, both ends of the fixed shaft 190 are detachably installed on the corresponding lifting blocks 180. Thus, the lifting blocks 180 are restricted and will not rotate circumferentially along the threaded rods 170.

[0040] Among them, through the setting of the sprockets 220 and the chain 210, the two threaded rods 170 can rotate synchronously, so that the lifting blocks 180 can be lifted and lowered synchronously on the threaded rods 170. Furthermore, it can preferably avoid the inclination of the fixed shaft 190 caused by the misaligned lifting of the lifting blocks 180, so that the cutting knives 230 cannot simultaneously abut against the non-woven fabric for better cutting.

[0041] In actual use, a driving motor 200 for driving the rotation of one of the two threaded rods 170 is provided inside the chamber, so that the driving motor 200 can drive the rotation of one of the two threaded rods 170. Through the cooperation of the sprockets 220 and the chain 210, the two threaded rods 170 can rotate synchronously, so that the two lifting blocks 180 can be lifted and lowered synchronously.

[0042] Among them, both ends of the threaded rod 170 are rotatably installed on the upper side surface of the base 100 and the bottom wall of the chamber through bearing seats. Thus, the rotational installation of the threaded rod 170 is preferably realized.

[0043] Among them, the upper end of the chamber is open, and a detachable cover plate is provided at the opening position. Through the setting of the cover plate, the components inside the chamber can be disassembled and assembled.

[0044] Combined Figure 4 As shown in the figure, in this embodiment, placing grooves 400 for the corresponding ends of the fixed shaft 190 to be inserted are provided on the opposite side walls of the lifting blocks 180. A clamping semi-ring 300 for clamping the fixed shaft 190 is provided at the opening of the placing groove 400. Fixing plates 310 that overlap on the side walls of the lifting blocks 180 are provided at both ends of the clamping semi-ring 300, and the fixing plates 310 are fixedly installed on the side walls of the lifting blocks 180 to realize the installation of the fixed shaft 190 in the placing groove 400.

[0045] In actual use of this embodiment, the fixing plate 310 is installed on the side wall of the lifting block 180 through bolts, so that the clamping semi-ring 300 can fixedly install the fixed shaft 190 in the placement groove 400, thereby preventing the fixed shaft 190 from detaching from the placement groove 400;

[0046] Among them, the fixing plate 310 is installed on the side wall of the lifting block 180 through bolts, which is convenient for disassembling the clamping semi-ring 300, and then convenient for taking out the fixed shaft 190 from the placement groove 400, so as to facilitate adding or reducing the slitting components on the fixed shaft 190;

[0047] Among them, in order to prevent the fixed shaft 190 from rotating in the placement groove 400, a limiting block 410 for extending into the limiting groove 340 is provided on the inner wall of the clamping semi-ring 300. Since the clamping semi-ring 300 is fixedly installed on the lifting block 180, the limiting block 410 is connected to the inner side wall of the clamping semi-ring 300 by welding, so that the limiting block 410 can be fixedly installed. Furthermore, when the limiting block 410 extends into the limiting groove 340, the side wall of the limiting groove 340 can abut against the side wall of the limiting block 410, thereby preventing the fixed shaft 190 from rotating in the placement groove 400.

[0048] Working principle: When slitting the non-woven fabric, one end of the non-woven fabric is sequentially passed through the fixed roller 111 and connected to an existing winding device through the pressing roller 140. The pressing roller 140 is pushed upward by the cylinder 120 to guide the non-woven fabric. Then, according to the width of the required non-woven fabric strips, the distance between the slitting knives 230 can be adjusted to an appropriate size by turning the sleeve 260. At this time, the slitting motor 240 is started to drive the slitting knives 230 to rotate. Then, the driving motor 200 is started to synchronously rotate the two threaded rods 170 to drive the two lifting blocks 180 to synchronously descend, so that the slitting knives 230 abut against the non-woven fabric. At this time, the winding device is started to drive the winding of the non-woven fabric, and the slitting of the non-woven fabric by the slitting knives 230 is realized.

[0049] In summary, the above are only the preferred embodiments of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope covered by the patent of the present invention.
