Abstract

The present invention discloses a cloth-cutting device for a double-sided computer jacquard knitting machine, and relates to the technical field of cloth production. The device comprises a housing, with a take-up roller fixedly connected to one side of the top of the housing and a winding roller fixedly connected to the other side. A tensioning mechanism is provided in the center of the top of the housing. The tensioning mechanism comprises two symmetrically arranged support frames, each of which is rotatably connected to a first screw rod. Sliding blocks that can slide up and down along the first screw rod are threadedly connected to the first screw rods in the two support frames. A tensioning roller is rotatably connected between the two sliding blocks. A pressure sensor is mounted on the outer wall of the middle portion of the tensioning roller. A clamping assembly is provided on one side of the support frame. A cloth-cutting mechanism is provided on the tensioning mechanism. During use, the pressure sensor monitors the pressure of the cloth on the tensioning roller in real time.

This can prevent the cloth from wrinkling due to being too loose or from stretching and deforming due to being too tight.

Description

Technical Field

[0001] The invention relates to the technical field of cloth production, in particular to a cloth cutting device for a double-sided computer jacquard knitting machine. Background Art

[0002] During the fabric production and processing process, fabric slitting equipment is required. Existing fabric slitting equipment, such as the one described in Patent Publication No. CN218561915U for double-layer fabrics, includes a frame with a mounting seat having a knife groove within it, a slitting knife within the knife groove, a fixing hole within the slitting knife, a groove within the mounting seat, a socket on the bottom of the groove communicating with the fixing hole, a mounting plate within the groove, and an insertion rod on the bottom of the mounting plate. This application improves the convenience of installing and removing the slitting knife.

[0003] However, during the use of the above-mentioned equipment, due to the setting of its internal cutting knife, the double-sided jacquard fabric has a sensitive cutting tension due to its complex structure (such as the difference in coil density on the front and back sides). Traditional cutting equipment often uses fixed tension rollers or simple spring adjustments, which are difficult to adapt to double-sided jacquard fabrics of different weights and thicknesses. At the same time, due to the difference in coil structure on the front and back sides of double-sided jacquard knitted fabrics (such as plain weave on the front and rib on the back), the local thickness is uneven, and the fixed-angle knife is prone to cause the incision to tilt or stretch deformation, reducing work efficiency. Therefore, in response to this situation, we propose a more convenient and practical cutting equipment to meet the use needs. Summary of the Invention

[0004] The object of the present invention is to provide a cloth cutting device for a double-sided computerized jacquard knitting machine to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A cloth-cutting device for a double-sided computerized jacquard knitting machine, comprising a housing, a winding roller fixedly connected to one side of the top of the housing, and a winding roller fixedly connected to the other side, a tensioning mechanism provided in the center of the top of the housing, the tensioning mechanism comprising two symmetrically arranged support frames, both of which are rotatably connected to a first screw rod, a sliding block threadedly connected to the first screw rod inside the two support frames and capable of sliding up and down along the first screw rod, a tensioning roller rotatably connected between the two sliding blocks, a pressure sensor installed on the outer wall of the middle portion of the tensioning roller, a clamping assembly provided on one side of the support frame, and a cloth-cutting mechanism provided on the tensioning mechanism;

[0007] The cloth-cutting mechanism includes a mounting plate, which is connected to the supporting frame, and the bottom center of the mounting plate is fixedly connected to the supporting plate, and the supporting plate is rotatably connected to a rotating shaft, one end of the rotating shaft is fixedly connected to a first bevel gear, and the bottom center of the support plate is rotatably connected to a second bevel gear, and the first bevel gear and the second bevel gear are meshed; the rotating shaft is fixedly connected to the mounting frame at one end away from the first bevel gear, and a cylinder is installed on the inner wall of the mounting frame, and the output end of the cylinder is fixedly connected to a fixing frame, and the top of the fixing frame is fixedly connected to a lifting plate; the top of the lifting plate is rotatably connected to a connecting shaft, one end of the connecting shaft is fixedly connected to a blade, and the other end is fixedly connected to a sprocket, and a chain is installed on the outer wall of the sprocket.

[0008] Furthermore, the clamping assembly includes a fixed plate, which is connected to the support frame. One side of the fixed plate is rotatably connected to a guide roller, and the outer walls of both ends of the guide roller are slidably connected to the clamping plate. The bottom of the fixed plate is rotatably connected to a bidirectional screw, and the bidirectional screw and the clamping plate are threadedly connected.

[0009] Furthermore, it also includes an adjustment mechanism;

[0010] The adjustment mechanism includes a fixed frame arranged on the shell, a lifting block is slidably connected to the inner wall of one side of the fixed frame, a second screw rod is rotatably connected to the top of the fixed frame, the second screw rod and the lifting block are threadedly connected, and a connecting frame is fixedly connected to one side of the lifting block.

[0011] Furthermore, through holes are opened on both sides of the connecting frame, and sliding columns are slidably connected in the through holes. One end of the sliding column is fixedly connected to a fixed block. A spring is installed on the outer wall of the sliding column, and a clamping roller is rotatably connected to one side of the fixed block.

[0012] Furthermore, it also includes a dust collection mechanism;

[0013] The dust collection mechanism includes a dust collection funnel arranged on the outer shell, the dust collection funnel is arranged on the inner wall of the top of the outer shell, the top of the dust collection funnel is fixedly connected to a connecting pipe, one end of the connecting pipe is fixedly connected to a filter box, the filter box and the outer shell are connected, a plurality of equidistant slots are opened on one side of the filter box, filter plates are inserted in the slots, and a dust collector is installed on one side of the filter box.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The cloth cutting device of the double-sided computer jacquard knitting machine passes the cloth through the tensioning roller and the guide roller through the arrangement of the tensioning mechanism, the cloth cutting mechanism, the adjustment mechanism and the dust suction mechanism during use. At the same time, the pressure sensor monitors the pressure of the cloth on the tensioning roller in real time and transmits the signal to the control system. If the pressure is abnormal, the control system drives the first screw to rotate, drives the sliding block to slide on the inner wall of the support frame, drives the tensioning roller to rise or fall until the pressure returns to normal. At the same time, when the cloth deviates, the control system drives the bidirectional screw to rotate and drives the clamping plate to slide along the guide roller to adjust the position of the cloth. By detecting the tension force in real time, the tension adjustment is realized, which can prevent the cloth from wrinkling due to being too loose or stretching and deforming due to being too tight. The practicality is strong and suitable for promotion.

[0016] At the same time, the cloth cutting mechanism can fine-tune the cutting angle of the tool for different areas, so that the blade is always perpendicular to the direction of the cloth fiber, reducing the burrs of the cut. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figures 1-6 As shown, the present invention provides a cloth cutting device for a double-sided computer jacquard knitting machine, comprising a shell 1, a winding roller 2 is fixedly connected to one side of the top of the shell 1, and a winding roller 3 is fixedly connected to the other side, a tensioning mechanism 4 is provided in the center of the top of the shell 1, the tensioning mechanism 4 comprises two symmetrically arranged support frames 401, the two support frames 401 are both rotatably connected to the inside of the first screw rod 403, the first screw rod 403 in the two support frames 401 are both threadedly connected to a sliding block 402 that can slide up and down along the first screw rod 403, a tensioning roller 404 is rotatably connected between the two sliding blocks 402, a pressure sensor 405 is installed on the outer wall of the middle part of the tensioning roller 404, a clamping assembly is provided on one side of the support frame 401, and a cloth cutting mechanism 5 is provided on one side of the tensioning mechanism 4, and an adjusting mechanism 6 and a dust suction mechanism 7 are also provided on the shell 1.

[0027] like Figure 3 As shown, the clamping assembly includes a fixed plate 406, which is connected to the support frame 401. One side of the fixed plate 406 is rotatably connected to a guide roller 409, and the outer walls of both ends of the guide roller 409 are slidably connected to the clamping plate 407. The bottom of the fixed plate 406 is rotatably connected to a bidirectional screw 408, and the bidirectional screw 408 and the clamping plate 407 are threadedly connected.

[0028] It should be noted that during use, the cloth passes through the tensioning roller 404 and the guide roller 409, and the pressure sensor 405 monitors the pressure of the cloth on the tensioning roller 404 in real time, and transmits the signal to the control system (not shown in the figure). If the pressure is abnormal, the control system drives the first screw 403 to rotate, driving the sliding block 402 to slide on the inner wall of the support frame 401, and then drives the tensioning roller 404 to rise or fall until the pressure returns to normal. At the same time, when the cloth deviates, the control system drives the bidirectional screw 408 to rotate, driving the guide roller 409 on the clamping plate 407 to move left and right, and adjust the position of the cloth.

[0029] like Figure 4 As shown, the cloth cutting mechanism 5 includes a mounting plate 501, which is connected to the support frame 401, and a support plate 502 is fixedly connected to the bottom center of the mounting plate 501, and a rotating shaft 503 is rotatably connected to one side of the support plate 502, and one end of the rotating shaft 503 is fixedly connected to a first bevel gear 504, and the bottom center of the support plate 502 is rotatably connected to a second bevel gear 505, and the first bevel gear 504 and the second bevel gear 505 are meshed with each other, and the rotating shaft 503 is fixedly connected to a mounting frame 506 at one end away from the first bevel gear 504, and a cylinder 507 is installed on the inner wall of the mounting frame 506, and the output end of the cylinder 507 is fixedly connected to a fixing frame 508, and a lifting plate 509 is fixedly connected to the top of the fixing frame 508, and the lifting plate 509 is rotatably connected to a connecting shaft 510, and one end of the connecting shaft 510 is fixedly connected to a blade 511, and the other end is fixedly connected to a sprocket 512, and a chain 513 is installed on the outer wall of the sprocket 512.

[0030] It should be noted that during use, when the cloth passes through the tensioning roller 404, the motor drives the second bevel gear 505 to rotate, which drives the first bevel gear 504 and the rotating shaft 503 to rotate through engagement, and the mounting frame 506 rotates accordingly. At the same time, the cylinder 507 pushes the lifting plate 509 and the fixing frame 508 to move up and down, adjusting the cutting depth of the blade 511. Finally, the motor drives the sprocket 512 to rotate, driving the chain 513 to rotate, thereby adjusting the angles of multiple blades 511 through the connecting shaft 510. The cloth cutting mechanism 5 can fine-tune the tool cutting angle for different areas, so that the blade is always perpendicular to the direction of the cloth fiber, reducing the burrs on the cut.

[0031] like Figure 5As shown, the adjustment mechanism 6 includes a fixed frame 601 provided on the housing (1), the inner wall of one side of the fixed frame 601 is slidably connected to a lifting block 602, the top of the fixed frame 601 is rotatably connected to a second screw rod 603, the second screw rod 603 and the lifting block 602 are threadedly connected, one side of the lifting block 602 is fixedly connected to a connecting frame 604, both sides of the connecting frame 604 are provided with through holes (not marked in the figure, but those skilled in the art should understand the location of the through holes), a sliding column 605 is slidably connected in the through hole, one end of the sliding column 605 is fixedly connected to a fixed block 606, a spring 607 is installed on the outer wall of the sliding column 605, and one side of the fixed block 606 is rotatably connected to a clamping roller 608.

[0032] It should be noted that during use, the cloth is first passed through the clamping roller 608, and then the second screw 603 rotates, driving the lifting block 602 to move up and down along the inner wall of the fixed frame 601, driving the connecting frame 604 to rise synchronously, and the connecting frame 604 drives the clamping roller 608 on the fixed block 606 to adjust its height accordingly, so that the cloth is always in the appropriate position. During this process, the spring 607 can buffer the fluctuation of cloth tension and ensure that the clamping roller 608 is closely attached to the cloth surface. When the cloth width changes or there is a slight deviation, the spring 607 automatically adjusts the clamping force and cooperates with the tensioning mechanism 4 to maintain stable cloth transmission, avoid deviation or wrinkles, and achieve adjustment.

[0033] like Figure 6 As shown, the dust collection mechanism 7 includes a dust collection funnel 701 arranged on the housing (1), the dust collection funnel 701 is arranged on the top inner wall of the housing 1, the top of the dust collection funnel 701 is fixedly connected to a connecting pipe 702, one end of the connecting pipe 702 is connected to a filter box 704, the filter box 704 and the housing 1 are connected, and a plurality of equidistant slots are opened on one side of the filter box 704 (not marked in the figure, but those skilled in the art should understand the position of the slots), a filter plate 705 is inserted into the slot, and a dust collector 703 is installed on one side of the filter box 704.

[0034] It should be noted that during use, when the cloth cutting mechanism 5 is working, the vacuum cleaner 703 starts to suck the debris generated during cloth cutting into the filter box 704 through the connecting pipe 702 and the dust collection funnel 701, and filters it through the filter plate 705. The dust collection mechanism 7 can quickly suck out dust to prevent dust from polluting the workshop air.

[0035] When using this equipment, you need to ensure that the fabric is flat and in the center of the clamping roller 608 when placing the fabric to avoid poor cloth cutting effect or equipment damage due to fabric deviation. When adjusting the adjustment mechanism 6, you need to make reasonable adjustments according to the thickness and hardness of the fabric to ensure that the distance between the clamping roller 608 and the fabric is appropriate to ensure the cloth cutting quality and equipment stability. Before starting the cloth cutting mechanism 5, you need to confirm whether the blade 511 is sharp and installed correctly to avoid poor cloth cutting effect or safety hazards due to problems with the blade 511.

[0036] More specific:

[0037] During use, the cloth is introduced through the winding roller 2, led out by the winding roller 3, passes through the tensioning roller 404, and the tension is monitored and fed back in real time through the pressure sensor 405. The position of the sliding block 402 is adjusted through the first screw rod 403, and the height of the tensioning roller 404 is dynamically adjusted to maintain constant tension. Then the cloth enters the cloth cutting mechanism 5, and the motor drives the second bevel gear 505 to drive the first bevel gear 504 and the rotating shaft 503 to rotate and adjust the angle of the blade 511. At the same time, the cylinder 507 pushes the lifting plate 509 to adjust the cutting depth of the blade 511. Then the motor drives the sprocket 512 to rotate, driving the chain 513 to rotate, thereby adjusting the multiple The angle of each blade 511 is adjusted, and the cloth passes through the clamping roller 608. Then the second screw 603 rotates, driving the lifting block 602 to move up and down along the inner wall of the fixed frame 601, driving the connecting frame 604 to rise synchronously, and the connecting frame 604 drives the clamping roller 608 on the fixed block 606 to adjust the height accordingly. Through cooperation with the tensioning roller 404, the cloth is always in the appropriate position to ensure that the cloth is centered and stable. The dust generated by the cutting is collected by the dust collection funnel 701, sucked into the filter box 704 by the vacuum cleaner 703, and then discharged after purification. The tension is adjusted by real-time detection of the tension force, which can prevent the cloth from wrinkling due to being too loose or stretching and deforming due to being too tight.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is limited by the accompanying embodiments and their equivalents.
