Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric processing, in particular to a non-woven fabric cutting machine with a deviation rectifying feeding mechanism. Background Technique

[0002] A non-woven fabric cutting machine is a device specifically used for cutting and processing non-woven fabric materials. Non-woven fabric is a fabric formed by the entanglement of fibers with each other and is widely used in the fields of medical treatment, hygiene, agriculture, environmental protection, etc. During the processing of non-woven fabric, the accuracy and efficiency of the cutting machine are crucial for the quality of the final product. A non-woven fabric cutting machine generally includes a feeding system, a cutting tool, a control system and other components, aiming to achieve efficient and precise cutting of non-woven fabric.

[0003] The patent with the publication number of CN216193602U discloses a non-woven fabric cutting device, in which the third roller presses down the fabric to make the fabric closely fit with the conveyor belt, facilitating the trimming of the fabric edge. When the first motor is turned on, the first motor drives the second driving wheel to rotate, thereby driving the conveyor belt to move, facilitating the transportation of non-woven fabric; it includes a workbench, a feeding plate, a first bracket, a tensioning roller, a first rotating shaft and a bearing. The feeding plate is installed on the right part of the workbench, the first bracket is installed at the left end of the workbench, the first bracket is provided with a first placement opening, the tensioning roller is installed on the first rotating shaft, the first rotating shaft is rotatably installed with the bearing, and the bearing is installed in the first placement opening; it also includes a second bracket, a first roller, a second roller, a conveyor belt, a first driving wheel, a first motor, a second driving wheel, a belt, a first sliding bracket, a slider, a spring group, an elongation frame and a third roller. The second bracket is installed on the top of the workbench, and the first roller is rotatably installed at the right end of the second bracket.

[0004] However, this prior art has significant deficiencies during the cutting process. First of all, during cutting, it is impossible to ensure that the fabric is always in the correct position, resulting in possible fabric deviation, which directly affects the cutting accuracy, causing incorrect cutting positions and thus affecting the quality of non-woven fabric. Secondly, during cutting, the third roller presses down the fabric to make the fabric closely fit with the conveyor belt, and then the bottom end of the trimming cutter is used to trim the fabric edge. When the trimming cutter cuts non-woven fabric, it may accidentally damage the conveyor belt, which not only affects the normal operation of the machine but also increases the maintenance cost. Therefore, aiming at these defects, we propose a non-woven fabric cutting machine with a deviation rectifying feeding mechanism, aiming to effectively solve the feeding deviation problem by introducing an active deviation rectifying mechanism, ensuring the stability of the fabric during the cutting process, thereby improving the cutting accuracy and efficiency and extending the service life of the equipment. Summary of the Invention

[0005] The purpose of the utility model is to provide a non-woven fabric cutting machine with a deviation rectifying feeding mechanism to solve the problems raised in the above background technique.

[0006] To achieve the above object, the utility model provides the following technical solutions:

[0007] A non-woven fabric cutting machine with a deviation-correcting feeding mechanism, including a base, as Figure 1 shown, a deviation-correcting feeding assembly, a cutting assembly, a support guiding member, and a non-woven fabric winding mechanism are successively arranged on the top of the base from front to back. The non-woven fabric winding mechanism is used for winding the cut non-woven fabric, which is prior art and will not be elaborated here. The non-woven fabric winding mechanism, in cooperation with the deviation-correcting feeding assembly, the support guiding member, and the non-woven fabric production equipment, can tighten the non-woven fabric to ensure that the cutting assembly can perform cutting operations on both sides of the non-woven fabric;

[0008] As Figure 3 shown, the deviation-correcting feeding assembly includes a U-shaped bracket bolted to the top of the base, providing an installation base for the deviation-correcting assembly. Two photoelectric sensors arranged symmetrically left and right are provided at the top of the U-shaped bracket near the front side, which are connected to an external power supply and a controller to work, for real-time monitoring of the edge position of the non-woven fabric and feeding back an offset signal to the controller, and the controller controls the electric cylinder to work. A U-shaped movable plate that can be adjusted left and right is provided at the top of the U-shaped bracket near the rear side, for driving the feeding roller to move horizontally to correct the offset of the fabric. A feeding roller is rotatably connected between the left and right sides of the inner wall of the U-shaped movable plate, for driving the conveyance of the non-woven fabric. A motor for driving the rotation of the feeding roller is provided on the right side of the U-shaped movable plate, which is connected to an external power supply to work and provides the rotational power for the feeding roller;

[0009] As Figure 5 shown, the cutting assembly includes two first fixed vertical plates arranged symmetrically left and right, supporting a bidirectional lead screw and a second slide bar. A bidirectional lead screw is rotatably connected between the two first fixed vertical plates near the top, for driving the moving blocks to move synchronously in opposite directions or relatively by means of threads to adjust the distance between the cutting knives. The left end of the bidirectional lead screw passes through the inner side of the first fixed vertical plate and is fixedly connected to a knob for manually adjusting the rotation of the bidirectional lead screw. Moving blocks are threadedly connected to both threaded sections of the bidirectional lead screw, for driving the U-shaped connecting block and the cutting knife to move horizontally. A U-shaped connecting block is provided at the bottom of the moving block, connecting the moving block and the cutting knife and facilitating the replacement of the cutting knife. The U-shaped connecting block is bolted with a cutting knife for cutting the edge of the non-woven fabric.

[0010] Preferably, as shown in combination with Figure 3 and Figure 4 shown, two support fixing blocks arranged symmetrically left and right are provided at the top of the U-shaped bracket near the rear side, fixing the first slide bar and providing sliding support for the U-shaped movable plate. Two first slide bars arranged symmetrically front and back are provided between the two support fixing blocks, providing guidance for the horizontal movement of the moving seat;

[0011] A moving seat is provided in the middle of the bottom of the U-shaped movable plate. The moving seat is slidably connected to the outer sides of two first sliding rods to connect the U-shaped movable plate and the first sliding rods to ensure sliding stability.

[0012] An electric cylinder is provided on the top of the left side of the U-shaped bracket through a mounting plate. The photoelectric sensor and the electric cylinder are electrically connected to the controller through wires respectively. The movable rod of the electric cylinder is fixedly connected to the left side of the U-shaped movable plate to drive the U-shaped movable plate to move horizontally to achieve active deviation correction.

[0013] Preferably, as Figure 5 shown, a second sliding rod is provided between the two first fixed vertical plates and near the bottom of the bidirectional lead screw. Both of the moving blocks are slidably connected to the outer side of the second sliding rod to limit the moving blocks to move only in the horizontal direction.

[0014] Preferably, as Figure 1 shown, the support and guide member includes two second fixed vertical plates arranged symmetrically left and right to support and guide the roller and keep its position stable. A guide roller is rotatably connected between the two second fixed vertical plates to cooperate with the feeding roller to maintain the non-woven fabric in a tensioned state.

[0015] The outer diameter of the guide roller is the same as that of the feeding roller, and the guide roller and the feeding roller have the same height. The cutting knife is located between the guide roller and the feeding roller.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] 1. For the non-woven fabric cutting machine with a deviation correction feeding mechanism, the edge position of the non-woven fabric is monitored in real time by the photoelectric sensor. Combining the linkage adjustment of the electric cylinder and the U-shaped movable plate, the horizontal movement of the feeding roller is controlled in real time, and the deviation of the non-woven fabric during transportation is dynamically corrected, ensuring that the fabric is always on the preset path during the cutting process, avoiding cutting errors caused by fabric deviation, and significantly improving the cutting accuracy.

[0018] 2. For the non-woven fabric cutting machine with a deviation correction feeding mechanism, the bidirectional lead screw drives the moving blocks to move synchronously through the knob, driving the U-shaped connecting block and the cutting knife to horizontally adjust the cutting width. When cutting, the cutting knife keeps a safe distance from the feeding roller and the guide roller, and can adapt to the cutting requirements of non-woven fabrics with different widths.

[0019] 3. For the non-woven fabric cutting machine with a deviation correction feeding mechanism, the feeding roller and the guide roller are designed with the same outer diameter and height, so that the non-woven fabric is always maintained in a uniform tensioned state during transportation, avoiding cutting misalignment caused by fabric relaxation or jitter, and improving the cutting efficiency and the consistency of the finished products.

[0020] 4. The non-woven fabric cutting machine with a deviation-correcting feeding mechanism has a cutting knife bolted to a U-shaped connecting block. The bidirectional lead screw can be manually adjusted through a knob, and the support fixing block and the first sliding rod provide stable sliding guidance for the U-shaped movable plate.

[0029] Please refer to Figures 1 - 5 , the present utility model provides a technical solution:

[0030] A non-woven fabric cutting machine with a deviation rectifying feeding mechanism, including a base 100, as Figure 1 shown, a deviation rectifying feeding assembly 300, a cutting assembly 400, a support guiding member 500, and a non-woven fabric winding mechanism 200 are sequentially arranged on the top of the base 100 from front to back. The non-woven fabric winding mechanism 200 is used to wind the cut non-woven fabric, which is prior art and will not be elaborated here. The non-woven fabric winding mechanism 200, in cooperation with the deviation rectifying feeding assembly 300, the support guiding member 500, and the non-woven fabric production equipment, can tighten the non-woven fabric to ensure that the cutting assembly 400 can perform cutting operations on both sides of the non-woven fabric;

[0031] As Figure 3 shown, the deviation rectifying feeding assembly 300 includes a U-shaped bracket 310 installed on the top of the base 100 by bolts, providing an installation base for the deviation rectifying assembly. At a position near the front side of the top of the U-shaped bracket 310, two photoelectric sensors 320 arranged symmetrically left and right are provided. They are connected to an external power supply and a controller to work, used to monitor the edge position of the non-woven fabric in real time and feedback the deviation signal to the controller, and the controller controls the electric cylinder 370 to work. At a position near the rear side of the top of the U-shaped bracket 310, a U-shaped movable plate 340 that can be adjusted left and right is provided, used to drive the feeding roller 350 to move horizontally to correct the deviation of the fabric. A feeding roller 350 is rotatably connected between the left and right sides of the inner wall of the U-shaped movable plate 340, used to drive the non-woven fabric to be conveyed. A motor 360 for driving the feeding roller 350 to rotate is provided on the right side of the U-shaped movable plate 340, which is connected to an external power supply to work and provides the rotational power for the feeding roller 350;

[0032] As Figure 5As shown, the cutting component 400 includes two first fixed vertical plates 410 arranged symmetrically left and right, a support bidirectional lead screw 420 and a second slide bar 450. A bidirectional lead screw 420 is rotatably connected between the two first fixed vertical plates 410 and near the top. The moving blocks 430 are driven by the thread to move synchronously in opposite directions or relatively to adjust the distance between the cutting knives 440. The left end of the bidirectional lead screw 420 passes through the inner side of the first fixed vertical plate 410 and is fixedly connected with a knob 460 for manually adjusting the rotation of the bidirectional lead screw 420. Both threaded areas of the bidirectional lead screw 420 are threadedly connected with moving blocks 430 for driving the U-shaped connecting block 431 and the cutting knife 440 to move horizontally. The bottom of the moving block 430 is provided with a U-shaped connecting block 431 for connecting the moving block 430 and the cutting knife 440 and facilitating the replacement of the cutting knife 440. The U-shaped connecting block 431 is bolted with a cutting knife 440 for cutting the edge of the non-woven fabric.

[0033] In this embodiment, in combination with Figure 3 and Figure 4 As shown, two support fixing blocks 330 arranged symmetrically left and right are provided at the top of the U-shaped bracket 310 and near the rear side for fixing the first slide bar 380 and providing sliding support for the U-shaped movable plate 340. Two first slide bars 380 arranged symmetrically front and back are provided between the two support fixing blocks 330 for guiding the lateral movement of the moving seat 341;

[0034] In the middle of the bottom of the U-shaped movable plate 340, there is a moving seat 341. The moving seat 341 is slidably connected to the outside of the two first slide bars 380 for connecting the U-shaped movable plate 340 and the first slide bar 380 to ensure sliding stability;

[0035] At the top of the left side of the U-shaped bracket 310, an electric cylinder 370 is provided through a mounting plate. The photoelectric sensor 320 and the electric cylinder 370 are respectively electrically connected to the controller through wires. The movable rod of the electric cylinder 370 is fixedly connected to the left side of the U-shaped movable plate 340 for driving the U-shaped movable plate 340 to move horizontally to achieve active deviation correction.

[0036] Specifically, as Figure 5 shown, a second slide bar 450 is provided between the two first fixed vertical plates 410 and near the bottom of the bidirectional lead screw 420. Both moving blocks 430 are slidably connected to the outside of the second slide bar 450 to limit the moving blocks 430 to move only in the horizontal direction.

[0037] Further, as Figure 1 shown, the support guide member 500 includes two second fixed vertical plates 510 arranged symmetrically left and right for supporting the guide roller 520 and maintaining its position stable. A guide roller 520 is rotatably connected between the two second fixed vertical plates 510 for cooperating with the feeding roller 350 to maintain the tension state of the non-woven fabric;

[0038] The outer diameter of the guiding roller 520 is the same as that of the feeding roller 350, the heights of the guiding roller 520 and the feeding roller 350 are the same, and the cutting knife 440 is located between the guiding roller 520 and the feeding roller 350.

[0039] When the non-woven fabric cutting machine with the belt deviation correction feeding mechanism of this embodiment is in use, the operator rotates the knob 460 to drive the bidirectional lead screw 420 to rotate, driving the two moving blocks 430 to move synchronously and reversely along the second slide bar 450, so as to adjust the distance between the cutting knives 440 on the U-shaped connecting block 431 to the required cutting width. Place the non-woven fabric roll on the unwinding mechanism of the non-woven fabric production equipment. The non-woven fabric passes through the feeding roller 350 of the deviation correction feeding assembly 300 and the guiding roller 520 of the support guiding member 500 in sequence, and finally is connected to the non-woven fabric winding mechanism 200. Start the non-woven fabric winding mechanism 200 and the deviation correction feeding assembly 300 to work. The motor 360 drives the feeding roller 350 to rotate, driving the non-woven fabric to be conveyed along the preset path. At this time, the photoelectric sensor 320 monitors the edge position of the non-woven fabric in real time. If deviation is detected, the controller controls the electric cylinder 370 to push the U-shaped movable plate 340 to move horizontally along the first slide bar 380, driving the feeding roller 350 to correct the deviation horizontally synchronously, ensuring that the fabric is always in the correct position. When the non-woven fabric is conveyed to the cutting station, the cutting knife 440 cuts both sides of the non-woven fabric. After the cut non-woven fabric is guided by the guiding roller 520 and maintained in a tensioned state, it is wound by the non-woven fabric winding mechanism 200. Thus, the continuous deviation correction, cutting and winding operations of the non-woven fabric are completed.
