Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric processing technology, specifically to an adjustable nonwoven fabric slitting device. Background Technology

[0002] In modern industrial production, nonwoven fabrics are a widely used material, and their slitting process is a crucial step in the production process. Nonwoven fabrics are used in various fields, including medical and health care, home decoration, agriculture, and industrial filtration. Different application scenarios have diverse requirements for the size and specifications of nonwoven fabrics. This makes efficient, precise, and low-loss nonwoven fabric slitting equipment an urgent need for industry development. Traditional nonwoven fabric slitting methods have many drawbacks. On the one hand, during the slitting process, due to the soft texture and certain flexibility of nonwoven fabrics, it is often difficult to fix them stably and position them precisely. This easily leads to inconsistent widths of the slitting nonwoven fabric strips, seriously affecting product quality and failing to meet the requirements of high-precision production. For example, in the production of medical dressings, uneven width of nonwoven fabric strips may affect the dressing... The nonwoven fabric's fit and protective effect are compromised, thus reducing product performance and reliability. On the other hand, traditional slitting devices lack effective tension adjustment mechanisms. If the nonwoven fabric cannot be evenly stretched and unfolded during slitting, wrinkles, folds, or even tears will occur. This not only causes a large waste of raw materials but also reduces production efficiency. In some industries with strict cost control, such as the manufacturing of disposable hygiene products, the waste of raw materials directly increases production costs and weakens the company's market competitiveness. In addition, existing slitting equipment usually cannot monitor the operating status of the slitting process in real time. For example, if the nonwoven fabric shifts during slitting and cannot be detected and adjusted in time, it will further aggravate product quality problems and may even damage the equipment, increase maintenance costs and downtime, and seriously affect the continuity and stability of production. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable nonwoven fabric slitting device to solve the problems of low slitting accuracy, easy waste of raw materials, and inability to monitor the slitting status in real time in the traditional nonwoven fabric slitting method mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adjustable nonwoven fabric slitting device, comprising a base, a top plate fixedly mounted on the upper surface of the base, a cutting electric push rod fixedly mounted on the upper end of the top plate, and a cutting blade fixedly mounted on the lower end of the cutting electric push rod, a support plate fixedly mounted on the upper surface of one end of the base, an adjusting electric push rod fixedly mounted on the outer surface of the base and the top plate, a mounting frame fixedly mounted on one end of the adjusting electric push rod, and rotating clamping rollers mounted on the opposite ends of the two mounting frames, and a tension adjustment mechanism provided on the outer surface of the base and the top plate, thereby ensuring that the nonwoven fabric can be stably slitted into strips by positioning and tensioning the ends of the nonwoven fabric, reducing the waste of raw materials.

[0005] Preferably, the traction adjustment mechanism includes: an adjustment motor, which is fixedly installed on the base and the top plate, and a displacement rod is fixedly connected to one end of the output shaft of the adjustment motor. A displacement frame is installed on the outer surface of the displacement rod, and a rotating angle frame is installed on the inner surface of the displacement frame. An angle motor is fixedly installed at one end of the displacement frame, and a dual-head drive motor is fixedly installed at one end of the angle frame. A drive wheel is fixedly connected to the output shaft of the dual-head drive motor.

[0006] Preferably, the displacement rod and the displacement frame are threadedly connected, and the displacement frame is slidably connected to the base and the top plate.

[0007] By adopting the above technical solution, the displacement frame can be driven to slide and adjust.

[0008] Preferably, there is a gap between adjacent drive wheels, and the gap between adjacent drive wheels is greater than the thickness of the cutting blade.

[0009] The above technical solution enables the drive wheel to pass through the cutting blade.

[0010] Preferably, a detection motor is fixedly installed inside the lower surface of the base, and the upper end of the output shaft of the detection motor passes through the upper surface of the base. A detection disk is fixedly connected to the upper end of the output shaft of the detection motor, and a detection column is fixedly installed on the upper surface of the detection disk. A sliding detection plate is installed on one outer surface of the detection column, and a pressing column is fixedly installed on the inner surface of the detection plate. A tactile switch is fixedly installed inside the side surface of the detection column opposite to the pressing column.

[0011] Preferably, the detection disk and the detection column are eccentrically arranged, and a spring connects the detection column and the detection plate.

[0012] By adopting the above technical solution, the detection plate can be reset under the pull of the spring.

[0013] Preferably, the detection plate is arc-shaped, and the detection plate and the detection column are concentrically arranged.

[0014] The above technical solution enables the detection plate to rotate synchronously with the detection column.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the adjustable nonwoven fabric slitting device:

[0016] 1. The tension adjustment mechanism adjusts its position and extends forward to clamp the end of the nonwoven fabric at the beginning of the slitting process, so that the end of the nonwoven fabric can be driven and cut by the cutting blade. In this way, the raw material at the end of the nonwoven fabric will not be wasted due to the connection with the tension structure in the early stage.

[0017] Furthermore, by using the method of cutting the ends of the non-woven fabric and moving them to the support plate, the support plate can support the cut non-woven fabric, so that the cut non-woven fabric will not droop downwards. This ensures that the non-woven fabric will not entangle with each other due to natural drooping before it is rolled up, which facilitates the subsequent handling and rolling of the non-woven fabric.

[0018] 2. By using a detection motor to drive the detection disc to rotate, the detection column can detect the position of the non-woven fabric through the detection plate during the rotation. The cutting work is stopped by triggering an electrical signal using a touch switch, thus avoiding material waste caused by continuing to cut when the non-woven fabric is misaligned.

[0019] Furthermore, by setting the detection plate and detection column eccentrically, the detection plate can rotate at a certain frequency to face the non-woven fabric. With this design, the effectiveness of the tactile switch can be automatically verified by using the detection motor to drive the detection plate to rotate at high speed instantaneously.

[0028] 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.

[0029] Please see Figures 1-7 This utility model provides a technical solution: an adjustable nonwoven fabric slitting device.

[0030] Example 1

[0031] This embodiment discloses: a base 1, a top plate 2 fixedly disposed on the upper surface of the base 1, and a cutting electric push rod 3 fixedly installed at the upper end of the top plate 2, and a cutting blade 4 fixedly installed at the lower end of the cutting electric push rod 3; a support plate 5 fixedly disposed on the upper surface of one end of the base 1; an adjusting electric push rod 6 fixedly disposed on the outer surface of the base 1 and the top plate 2, and an installation frame 7 fixedly disposed on one end of the adjusting electric push rod 6; and a rotating clamping roller 8 disposed on the opposite end of the two installation frames 7; and a tension adjustment mechanism disposed on the outer surface of the base 1 and the top plate 2. By positioning and tensioning the end of the nonwoven fabric, the nonwoven fabric can be stably cut into strips to reduce the waste of raw materials.

[0032] The traction adjustment mechanism includes: an adjustment motor 9, which is fixedly installed on the base 1 and the top plate 2. One end of the output shaft of the adjustment motor 9 is fixedly connected to a displacement rod 10, and a displacement frame 11 is installed on the outer surface of the displacement rod 10. A rotating angle frame 12 is installed on the inner surface of the displacement frame 11, and an angle motor 13 is fixedly installed on one end of the displacement frame 11. A dual-head drive motor 14 is fixedly installed on one end of the angle frame 12, and a drive wheel 15 is fixedly connected to the output shaft of the dual-head drive motor 14.

[0033] The displacement rod 10 is threadedly connected to the displacement frame 11, and the displacement frame 11 is slidably connected to the base 1 and the top plate 2.

[0034] There is a gap between adjacent drive wheels 15, and the gap between adjacent drive wheels 15 is greater than the thickness of the cutting blade 4;

[0035] Before starting the device, adjust the electric push rod 6 to open the clamping rollers 8. The adjusting motor 9, angle motor 13, and double-head drive motor 14 in the tension adjustment mechanism are all in the off state. The cutting electric push rod 3 is also in the retracted position. The cutting blade 4 is at a certain distance below the top plate 2, waiting for the non-woven fabric to be placed. Pass the end of the non-woven fabric between the upper and lower clamping rollers 8. At this time, start the adjusting motor 9 of the tension adjustment mechanism to make the displacement rod 10 rotate, which drives the displacement frame 11 to extend forward. Bring the angle frame 12 and its double-head drive motor 14 and drive wheel 15 close to the end of the non-woven fabric. Then, the angle motor 13 starts to drive the drive wheels 15 on both sides to clamp the end of the non-woven fabric. At the same time, adjust the electric push rod 6 to push the mounting frame 7, so that the clamping rollers 8 move towards each other to clamp and fix the non-woven fabric.

[0036] After the clamping roller 8 above the base 1 clamps the end of the nonwoven fabric, the adjusting motor 9 of the tension adjustment mechanism is started, causing the displacement rod 10 to rotate and drive the displacement frame 11 to move backward until the nonwoven fabric is fully opened under the clamping roller 8. The cutting electric push rod 3 extends downward according to the preset stroke, and the adjusting motor 9 of the tension adjustment mechanism is started, causing the displacement rod 10 to rotate and drive the displacement frame 11 to move backward until the end of the nonwoven fabric is in contact with one end of the support plate 5. When the nonwoven fabric slowly passes under the cutting knife 4, the cutting knife 4 performs a slitting operation on the nonwoven fabric, cutting the nonwoven fabric into strips. The double-head drive motor 14 continues to rotate, and the drive wheel 15 pulls the nonwoven fabric so that the nonwoven fabric is continuously driven to cut. Due to the supporting effect of the support plate 5 on the nonwoven fabric, the cut nonwoven fabric will not droop downward, ensuring the stability and regularity of the nonwoven fabric during the slitting process.

[0037] Example 2

[0038] This embodiment discloses, based on embodiment 1: a detection motor 16 is fixedly installed inside the lower surface of the base 1, and the upper end of the output shaft of the detection motor 16 penetrates the upper surface of the base 1. A detection disk 17 is fixedly connected to the upper end of the output shaft of the detection motor 16, and a detection column 18 is fixedly installed on the upper surface of the detection disk 17. A sliding detection plate 19 is installed on one outer surface of the detection column 18, and a pressing column 20 is fixedly installed on the inner surface of the detection plate 19. A tactile switch 21 is fixedly installed inside the side surface of the detection column 18 opposite to the pressing column 20.

[0039] The detection plate 17 and the detection column 18 are eccentrically set, and a spring connects the detection column 18 and the detection plate 19;

[0040] The detection plate 19 has an arc-shaped design, and the detection plate 19 and the detection column 18 are concentrically arranged;

[0041] During the cutting process, the detection motor 16 drives the detection disk 17 to rotate slowly. When the non-woven fabric deviates, the non-woven fabric squeezes the detection plate 19. The detection plate 19 slides relative to the detection column 18 and triggers the light touch switch 21 through the squeezing column 20, thereby causing the light touch switch 21 to send an emergency stop signal to stop the cutting.

[0042] When it is necessary to detect whether the tactile switch 21 is malfunctioning, if no cutting is being performed, the detection motor 16 is started to make the detection disk 17 rotate at high speed and then stop. At this time, the detection plate 19 stretches the spring under the action of centrifugal force and is driven to reset by the spring when the detection disk 17 stops rotating. The rebound force generated by the reset makes the detection plate 19 move to the initial position and then continue to move towards the tactile switch 21 to trigger the tactile switch 21. If the tactile switch 21 cannot be triggered, it can be determined that the tactile switch 21 is in a malfunctioning state.

[0043] 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
