Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric processing technology, specifically to a cutting and sealing workbench for nonwoven fabric. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth, is composed of oriented or random fibers. It is called cloth because it has the appearance and some properties of cloth. Non-woven fabric has the characteristics of being moisture-proof, breathable, flexible, lightweight, non-flammable, easy to decompose, non-toxic and non-irritating, rich in color, inexpensive, and recyclable.

[0003] Reference patent (Publication No.: CN218711704U; Publication Date: 2023-03-24) discloses an automatic cutting and sealing device for activated carbon nonwoven fabric, in the field of activated carbon fabric production and processing. It includes a support box, a moving mechanism at the bottom of one side of the support box, a positioning mechanism on one side of the moving mechanism, an instrument panel fixedly connected to the front of the support box, a support platform fixedly connected to the top of the support box, and a push rod motor fixedly connected to the top of the support platform. Through the push rod motor, support frame, first motor, screw, slider, cutting blade, guide mechanism, moving block, guide rod, and sealing device, the automatic cutting and sealing device for activated carbon nonwoven fabric can better cut and seal activated carbon nonwoven fabric of different thicknesses, avoiding the difficulty of cutting and sealing most activated carbon nonwoven fabrics of different thicknesses, thus bringing convenience to the use of activated carbon nonwoven fabric.

[0004] Existing nonwoven fabric processing equipment uses heat sealing machines or ultrasonic edge sealing machines and cutting knives for cutting. However, if the nonwoven fabric is in a loose state during processing, it is very easy to wrinkle or deform during edge sealing or cutting, and even damage the knives. Some equipment attempts to use rigid clamping and pulling methods to tension it, but this method lacks buffering. Excessive instantaneous tension can easily cause irreversible tensile damage or even tearing to the soft nonwoven fabric. Therefore, this utility model provides a nonwoven fabric cutting and edge sealing workbench. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cutting and sealing workbench for nonwoven fabrics. This solves the problem that existing nonwoven fabric processing equipment, such as heat sealing machines or ultrasonic sealing machines and cutting knives, uses cutting. However, if the nonwoven fabric is in a loose state during processing, it is very easy to wrinkle or deform during sealing or cutting, and may even damage the cutting tools. Some equipment attempts to use rigid clamping and pulling methods to tension the fabric, but this method lacks buffering, and the instantaneous excessive tension can easily cause irreversible tensile damage or even tearing to the soft nonwoven fabric.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a non-woven fabric cutting and sealing workbench, comprising a workbench body, wherein the workbench body is provided with an installation mechanism for cutting and sealing non-woven fabric, the installation mechanism comprising: The adjustment assembly includes a support shell fixed at both ends of the upper surface of the workbench body, a positioning bracket slidably connected inside the support shell, a first slide rail bracket fixed to the inner wall of the positioning bracket, an mounting block slidably connected to the inner wall of the first slide rail bracket, a cutting blade connected by a locking assembly on one side of the lower end of the mounting block, a fixing shell fixed to the side wall of the support shell, and a locking bolt threaded inside the fixing shell. The mounting assembly includes a second slide rail bracket fixed at both ends of the upper surface of the workbench body. A slide rod is slidably connected inside the second slide rail bracket. One end of the slide rod is provided with a slider connected by an elastic component. The upper end of the slider is provided with a clamping component for fixing the non-woven fabric.

[0007] Preferably, push rod motors are fixed at both ends of the main body of the worktable, the upper end of the push rod motor is fixedly connected to the positioning bracket, a lead screw is rotatably connected inside the first slide rail bracket, a motor for driving is provided at one end of the lead screw, the mounting block is threadedly connected to the lead screw, and a guide rod is fixed at the upper end of the first slide rail bracket, the guide rod is slidably connected to the mounting block.

[0008] Preferably, the locking assembly includes a slotted housing fixed to one side of the mounting block, a rod inserted into the inside of the slotted housing, a cutting blade fixedly connected to the lower end of the rod, a screw on one side of the slotted housing for installing and removing the rod, and an edge sealing device on the other side of the mounting block.

[0009] Preferably, one end of the second slide rail bracket is provided with an electric push rod, and the telescopic end of the electric push rod is fixed with a connecting bracket, which is fixedly connected to the slide rod.

[0010] Preferably, the elastic component includes a compression plate fixed to the upper and lower surfaces of one end of a slide rod, a slider located on the outer wall of the slide rod in a slidable connection, a cavity groove formed on the inner wall of the slider, the compression plate being slidably connected to the cavity groove, a shock-absorbing spring fixed to the inner wall of the compression plate, the other end of the shock-absorbing spring being fixedly connected to the inner wall of the cavity groove, a damping support rod provided on the inner ring of the shock-absorbing spring, and the damping support rod being fixedly connected to the slider.

[0011] Preferably, the clamping assembly includes a fixed plate fixed to the upper end of the slider, a pair of movable rods slidably connected inside the fixed plate, a pressure plate fixed to the lower end of the movable rods, a rubber strip provided on the lower end surface of the pressure plate, and a bolt rotatably connected to the upper end surface of the pressure plate, the bolt being threadedly connected to the fixed plate.

[0012] Beneficial effects This utility model provides a cutting and sealing workbench for non-woven fabrics. Compared with the prior art, it has the following advantages: Firstly, this invention places the non-woven fabric on a workbench, rotates the bolt, and moves the bolt downward within the fixed plate, pushing the movable rod and pressure plate downward. The rubber strip at the lower end of the pressure plate presses down on the non-woven fabric, thus fixing it in place. Then, the electric push rod is activated, and its telescopic end drives the slide rod to slide within the second slide rail bracket via a connecting bracket. The slide rod moves the slider and clamping assembly, stretching the pressed non-woven fabric to ensure its tension. During the stretching process, the shock-absorbing spring and damping rod of the elastic component act as buffers and dampers, preventing excessive stretching force from damaging the non-woven fabric.

[0013] Secondly, the motor output shaft of this utility model extends and retracts, driving the positioning bracket to slide up and down inside the supporting shell. After the positioning bracket slides to the target height, the locking bolt inside the fixed shell, which is fixed to the side wall of the supporting shell, is rotated, so that the locking bolt is inserted into the supporting shell and in close contact with the positioning bracket. The positioning bracket is fixed by the squeezing force, thus completing the height locking. The automatic height adjustment of the positioning bracket is realized by the push rod motor, which is more efficient than manual adjustment and can accurately adapt to the processing needs of non-woven fabrics of different thicknesses. With the squeezing and fixing structure of the fixed shell and the locking bolt, the positioning bracket can be effectively prevented from shaking during processing. The locking assembly realizes the disassembly and assembly of the cutting blade through the combination of the slot shell, the insert rod and the screw, without the need for complicated tools, reducing the downtime for cutting blade replacement and reducing equipment maintenance costs. It is especially suitable for the tool wear and replacement needs in batch processing scenarios. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a technical solution: a non-woven fabric cutting and sealing workbench, including a workbench body 1, on which an installation mechanism for cutting and sealing non-woven fabric is provided, the installation mechanism including: The adjustment assembly includes a support shell 2 fixed at both ends of the upper surface of the workbench body 1. A positioning bracket 201 is slidably connected inside the support shell 2. A first slide rail bracket 202 is fixed to the inner wall of the positioning bracket 201. An installation block 204 is slidably connected to the inner wall of the first slide rail bracket 202. A cutting blade 302 connected to the lower end of the installation block 204 is provided on one side via a locking assembly. A fixing shell 401 is fixed to the side wall of the support shell 2. A locking bolt 402 is threaded inside the fixing shell 401. The locking bolt 402 is inserted into the interior of the support shell 2 and contacts the positioning bracket 201 after lifting, thereby squeezing and fixing the positioning bracket 201. The mounting components include a second slide rail bracket 5 fixed at both ends of the upper surface of the workbench body 1. A slide rod 501 is slidably connected inside the second slide rail bracket 5. A slider 502 connected to one end of the slide rod 501 via an elastic component is provided. A clamping component for fixing the non-woven fabric is provided at the upper end of the slider 502.

[0018] In a preferred embodiment, push rod motors 4 are fixed at both ends of the workbench body 1. The upper ends of the push rod motors 4 are fixedly connected to the positioning brackets 201. A lead screw 203 is rotatably connected inside the first slide rail bracket 202. One end of the lead screw 203 is equipped with a motor for driving. The mounting block 204 is threadedly connected to the lead screw 203. A guide rod 205 is fixed at the upper end of the first slide rail bracket 202. The guide rod 205 is slidably connected to the mounting block 204. When the push rod motors 4 fixed at both ends of the workbench body 1 are started, the upper ends of the push rod motors 4 are fixedly connected to the positioning brackets 201. The motor output shaft extends and retracts, driving the positioning brackets 201 to support the outer shell. The internal sliding mechanism of the positioning bracket 201 allows it to slide up and down to the target height. After the positioning bracket 201 slides to the target height, the locking bolt 402 inside the fixed housing 401, which is fixed to the side wall of the supporting housing 2, is rotated. This causes the locking bolt 402 to insert into the supporting housing 2 and make tight contact with the positioning bracket 201. The positioning bracket 201 is fixed by the squeezing force, thus completing the height locking. The automatic height adjustment of the positioning bracket 201 is achieved by the push rod motor 4, which is more efficient than manual adjustment and can accurately adapt to the processing requirements of non-woven fabrics of different thicknesses. The squeezing and fixing structure of the fixed housing 401 and the locking bolt 402 can effectively prevent the positioning bracket 201 from shaking during the processing.

[0019] In a preferred embodiment, the engaging assembly includes a slotted housing 3 fixed to one side of the mounting block 204. A rod 301 is inserted into the slotted housing 3, and a cutting blade 302 is fixedly connected to the lower end of the rod 301. A screw is provided on one side of the slotted housing 3 for installing and removing the rod 301. An edge sealing device 303 is provided on the other side of the mounting block 204. A motor drives the lead screw 203 to rotate within the first slide rail bracket 202. Since the mounting block 204 is threadedly connected to the lead screw 203, and under the guidance of the guide rod 205, the mounting block 204 moves horizontally along the first slide rail bracket 202, driving the cutting blade 302 to move horizontally to a suitable position for cutting and edge sealing. By integrating the edge sealing device 303 and the cutting blade 302 onto the same mounting block 204, edge sealing and cutting are completed continuously in one pass.

[0020] Furthermore, during the movement, the edge sealing device 303 is usually a hot air or ultrasonic edge sealer that first heats and fuses the edge of the non-woven fabric, which is existing technology and will not be elaborated on further.

[0021] To install a new cutter 302, unscrew the screws on one side of the housing 3 to fix it, and pull the insert rod 301 out of the housing 3. Since the cutter 302 is fixedly connected to the lower end of the insert rod 301, the cutter 302 will be disassembled when the insert rod 301 is pulled out. When installing a new cutter 302, insert the insert rod 301 with the cutter 302 connected to it into the housing 3, and then tighten the screws to fix the insert rod 301, thus completing the quick installation of the cutter 302.

[0022] In a preferred embodiment, an electric push rod 601 is provided at one end of the second slide rail bracket 5. A connecting bracket 6 is fixed to the telescopic end of the electric push rod 601. The connecting bracket 6 is fixedly connected to the slide rod 501. The elastic component includes a compression plate 701 fixed to the upper and lower surfaces of one end of the slide rod 501. A slider 502 is slidably connected to the outer wall of the slide rod 501. A cavity groove 7 is formed on the inner wall of the slider 502. The compression plate 701 is slidably connected to the cavity groove 7. A shock-absorbing spring 702 is fixed to the inner wall of the compression plate 701. The other end of the shock-absorbing spring 702 is fixedly connected to the inner wall of the cavity groove 7. The inner ring of the shock-absorbing spring 702 is provided with damping. Support rod 703, damping support rod 703 is fixedly connected to slider 502. Clamping assembly includes fixed plate 503 fixed to the upper end of slider 502. A pair of movable rods 504 are slidably connected inside fixed plate 503. Pressure plate 505 is fixed to the lower end of movable rod 504. Rubber strip is provided on the lower end surface of pressure plate 505. Bolt 506 is rotatably connected to the upper end surface of pressure plate 505. Bolt 506 is threadedly connected to fixed plate 503. The position of pressure plate 505 is controlled by electric push rod 601. After pressure plate 505 presses the nonwoven fabric on the worktable, electric push rod 601 retracts to stretch the pressed nonwoven fabric and ensure tension.

[0023] Specifically, the nonwoven fabric is placed on the workbench, and the bolt 506 is rotated. The bolt 506 moves downward within the fixed plate 503, pushing the movable rod 504 and the pressure plate 505 downward. The rubber strip at the lower end of the pressure plate 505 presses down on the nonwoven fabric, thus fixing it in place. The electric push rod 601 is then activated. The telescopic end of the electric push rod 601 drives the slide rod 501 to slide within the second slide rail bracket 5 via the connecting bracket 6. The slide rod 501 drives the slider 502 and the clamping assembly to move, stretching the pressed nonwoven fabric and ensuring its tension. During the stretching process, the shock-absorbing spring 702 and the damping support rod 703 of the elastic component provide buffering and shock absorption, preventing excessive stretching force from damaging the nonwoven fabric.

[0024] The motor model used above is MSMF042L1U2M, the linear actuator motor model is TOMUU U1, and the electric linear actuator model is DOOYA DT500.

[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0026] During operation, the operator lays the nonwoven fabric blank flat on the main body 1 of the workbench. Then, the operator rotates the bolts 506 in the clamping assembly at the upper end of each slider 502, driving the movable rod 504 and the pressure plate 505 downward. The rubber strip on the lower end of the pressure plate 505 is used to press the edge of the nonwoven fabric to achieve initial fixation. Next, the electric push rod 601 at one end of the second slide rail bracket 5 is activated. Its telescopic end pulls the slide rod 501 to slide in the second slide rail bracket 5 through the connecting bracket 6. The slide rod 501 transmits the tension to the slider 502 and the clamping assembly through the elastic assembly composed of the compression plate 701, the shock-absorbing spring 702 and the damping support rod 703, thereby smoothly stretching the already pressed nonwoven fabric. During this process, the elastic assembly effectively buffers and balances the tension, ensuring that the nonwoven fabric obtains and maintains appropriate tension without being damaged. During the processing preparation stage, the push rod motors 4 at both ends of the workbench body 1 are started to drive the positioning bracket 201 to rise and fall within the support shell 2. After adjusting to the target height, the locking bolt 402 inside the fixed shell 401 is tightened so that its end presses against the positioning bracket 201 to complete rigid locking. Finally, the drive motor is started to make the lead screw 203 rotate within the first slide rail bracket 202, which drives the mounting block 204, which is threadedly connected to the lead screw 203 and guided by the guide rod 205, to move horizontally. The edge sealing device 303 on one side of the mounting block 204 first fuses and seals the edge of the non-woven fabric under tension. Then, the cutting blade 302 connected to the other side of the same mounting block 204 through the locking assembly follows up to precisely cut off the sealed part, thereby completing a work cycle efficiently and with high quality.
