Description

Technical Field

[0001] This utility model relates to the field of fabric slitting technology, specifically to a fabric slitting mechanism. Background Technology

[0002] Fabric is the main material of clothing. As one of the three elements of clothing, fabric can not only interpret the style and characteristics of clothing, but also directly affect the color and shape of clothing. In the production process, a whole piece of fabric needs to be cut into small pieces to facilitate segmented processing. However, most existing cutting mechanisms are semi-automatic. After cutting the fabric, the cut pieces need to be manually collected before the next cutting can be carried out. Therefore, a fabric cutting mechanism is proposed. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a fabric slitting mechanism.

[0004] The technical solution adopted by this utility model to solve its technical problem is a fabric slitting mechanism, including a slitting machine. A collection box is fixedly connected to the lower part of one side of the slitting machine. The collection box has a collection cavity inside. A second mounting plate and a third mounting plate are fixedly installed on the top of the collection box by bolts. A photoelectric sensor is installed on the side of the second mounting plate near the third mounting plate. A fourth mounting plate is fixedly installed on the upper part of one side of the slitting machine. There are two fourth mounting plates. A fabric roller is rotatably installed between the two fourth mounting plates. A motor is fixedly installed on one side of one of the fourth mounting plates. The output end of the motor is fixedly connected to one end of the fabric roller. The fabric roller is located directly above the collection box.

[0005] By adopting the above technical solution, the entire process of fabric placement, cutting, and collection is automated through the linkage of photoelectric sensors and PLC programs. When the fabric blocks the light beam, a signal is triggered, the motor is paused, and the electric cylinder is started to push the push plate. The spring and the pressure plate adaptively press the fabric. After the electrothermal cutting wire is precisely melted, the cut fabric automatically falls into the collection box. The photoelectric sensor then restores the signal and restarts the motor, forming a closed-loop control.

[0006] Specifically, a first mounting plate is fixedly connected to the middle of one side of the slitting machine. The first mounting plate is U-shaped. An electric cylinder is fixedly installed on the outer side of the first mounting plate. The output end of the electric cylinder passes through the first mounting plate and is fixedly connected to one side of a push plate. The push plate is located on the inner side of the first mounting plate.

[0007] By adopting the above technical solution, the electric cylinder serves as the cutting power source. It is activated after receiving a signal from a photoelectric sensor via a PLC, pushing the pusher plate horizontally towards the slitting machine. The U-shaped first mounting plate provides stable support for the cylinder.

[0008] Specifically, the side of the push plate away from the electric cylinder is fixedly connected to one end of a spring, and multiple springs are provided. The other end of the multiple springs is fixedly connected to one side of a pressing plate, and two pressing plates are provided.

[0009] Specifically, one side of each of the two pressing plates is fixedly connected to one end of a guide rod. Multiple guide rods are provided, and one end of each guide rod passes through a push plate and is fixedly connected to one side of a limiting plate. The limiting plate is located on the side of the push plate away from the pressing plates. Multiple springs are respectively sleeved on the outside of the multiple guide rods.

[0010] By adopting the above technical solution, when the push plate moves forward, the spring pushes the pressing plate to contact the fabric first. The spring deformation provides adaptive pressure to ensure that fabrics of different thicknesses can be stably pressed on the surface of the slitting machine, avoiding displacement during cutting. The spring is sleeved on the outside of the guide rod, which not only prevents the spring from deflecting, but also ensures the accuracy of the spring when it rebounds through the limiting plate, maintaining the reliability of the pressing action.

[0011] Specifically, a wire seat is fixedly installed on the side of the push plate away from the electric cylinder. There are two wire seats, and an electrothermal cutting wire is connected between the two wire seats.

[0012] By adopting the above technical solution, when the push plate moves forward, it drives the wire seat to move synchronously, so that the electrothermal cutting wire enters the cutting groove. After being energized, the wire heats up, and precise thermomelting cutting is achieved under the condition that the fabric is fixed by the pressing plate.

[0013] Specifically, the slitting machine has a cutting groove and a storage cavity on one side. There are two storage cavities, which are located at both ends of the cutting groove and are connected to the interior of the cutting groove.

[0014] By adopting the above technical solution, the cutting groove provides working space for the electrothermal cutting wire, and the wire is embedded in the cutting groove to complete the cutting during cutting; the storage cavity is used for the insertion of the wire holder to ensure that the electrothermal cutting wire can be embedded in the cutting groove.

[0015] The beneficial effects of this utility model are:

[0016] The fabric slitting mechanism described in this utility model achieves full automation of the fabric lowering, cutting, and collection process through the linkage of photoelectric sensors and PLC programs. When the fabric blocks the light beam, a signal is triggered, the motor is paused, and the electric cylinder is started to push the push plate. The spring and the pressure plate adaptively press the fabric. After the electrothermal cutting wire is precisely melted, the cut fabric automatically falls into the collection box. The photoelectric sensor then restores the signal and restarts the motor, forming a closed-loop control. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As one embodiment of this utility model, such as Figures 1-3 As shown, the fabric slitting mechanism of this utility model includes a slitting machine 3. A collection box 6 is fixedly connected to the lower part of one side of the slitting machine 3. A collection cavity 5 is opened inside the collection box 6. A second mounting plate 7 and a third mounting plate 9 are fixedly installed on the top of the collection box 6 by bolts. A photoelectric sensor 8 is installed on the side of the second mounting plate 7 near the third mounting plate 9. A fourth mounting plate 20 is fixedly installed on the upper part of one side of the slitting machine 3. There are two fourth mounting plates 20. A fabric roller 2 is rotatably installed between the two fourth mounting plates 20. A motor 1 is fixedly installed on one side of one of the fourth mounting plates 20. The output end of the motor 1 is fixedly connected to one end of the fabric roller 2. The fabric roller 2 is located directly above the collection box 6.

[0024] In use, the collection box 6 is used to receive the cut fabric. The second mounting plate 7 and the third mounting plate 9 on its top form a photoelectric detection area. When the fabric passes between the two mounting plates, it will block the light beam emitted by the photoelectric sensor 8, triggering a signal to control the start and stop of the cutting. After the cutting is completed, it will fall naturally into the collection chamber 5 to achieve automatic collection. The motor 1 drives the fabric roller 2 to rotate and release the rolled fabric. The start and stop are controlled by the PLC program in conjunction with the photoelectric sensor 8.

[0025] It should be noted that a sensor receiver is installed on the side of the third mounting plate 9 closest to the second mounting plate 7.

[0026] The present invention also includes a first mounting plate 4 fixedly connected to the middle of one side of the slitting machine 3. The first mounting plate 4 is U-shaped. An electric cylinder 10 is fixedly mounted on the outer side of the first mounting plate 4. The output end of the electric cylinder 10 passes through the first mounting plate 4 and is fixedly connected to one side of the push plate 15. The push plate 15 is located on the inner side of the first mounting plate 4.

[0027] In operation, the electric cylinder 10 serves as the cutting power source. It is activated after receiving a signal from the photoelectric sensor 8 via the PLC, pushing the pusher plate 15 to move horizontally towards the slitting machine 3. The U-shaped first mounting plate 4 provides stable support for the cylinder.

[0028] The present invention also includes that the side of the push plate 15 away from the electric cylinder 10 is fixedly connected to one end of the spring 17, and the spring 17 is provided in multiple forms. The other end of the multiple springs 17 is fixedly connected to one side of the pressing plate 16, and the pressing plate 16 is provided in two forms.

[0029] This utility model also includes that one side of the two pressing plates 16 is fixedly connected to one end of the guide rod 18, and the guide rod 18 is provided with multiple rods. One end of the multiple guide rods 18 passes through the push plate 15 and is fixedly connected to one side of the limiting plate 19. The limiting plate 19 is located on the side of the push plate 15 away from the pressing plate 16, and multiple springs 17 are respectively sleeved on the outside of the multiple guide rods 18.

[0030] When in use, when the push plate 15 moves forward, the spring 17 pushes the pressing plate 16 to contact the fabric first. The deformation of the spring 17 provides adaptive pressure to ensure that fabrics of different thicknesses can be stably pressed on the surface of the slitting machine 3, avoiding displacement during cutting. The spring 17 is sleeved on the outside of the guide rod 18, which not only prevents the spring 17 from deflecting, but also ensures the accuracy of the spring 17 when it rebounds through the limit plate 19, maintaining the reliability of the pressing action.

[0031] It should be noted that the two pressing plates 16 are distributed vertically, and the electrothermal cutting wire 13 is located between the two pressing plates 16.

[0032] The present invention also includes a wire seat 14 fixedly installed on the side of the push plate 15 away from the electric cylinder 10. The wire seat 14 is provided in two places, and an electrothermal cutting wire 13 is connected between the two wire seats 14.

[0033] When in use, the push plate 15 moves forward, causing the wire seat 14 to move synchronously, so that the electrothermal cutting wire 13 enters the cutting groove 12. After being powered on, the wire heats up, and precise thermomelting cutting is achieved under the condition that the fabric is fixed by the pressing plate 16.

[0034] It should be noted that the wire holder 14 has an internal power supply for heating the electrothermal cutting wire 13. When the electrothermal cutting wire 13 is powered on, it heats up and melts the fibers instantly when it comes into contact with the fabric, thus achieving cutting. This technology is electrothermal cutting technology, which is an existing mature technology and will not be described in detail here.

[0035] The present invention also includes a cutting groove 12 and a receiving cavity 11 on one side of the slitting machine 3. The receiving cavity 11 is provided in two places, and the two receiving cavities 11 are respectively located at both ends of the cutting groove 12. The receiving cavity 11 is connected to the interior of the cutting groove 12.

[0036] When in use, the cutting groove 12 provides working space for the electrothermal cutting wire 13. During cutting, the wire is embedded in the cutting groove 12 to complete the cutting. The storage cavity 11 is used for the insertion of the wire holder 14 to ensure that the electrothermal cutting wire 13 can be embedded in the cutting groove 12.

[0037] In use, the fabric is first wound onto the outside of the fabric roller 2. Then, the motor 1 is started to drive the fabric roller 2 to rotate. The rotation of the fabric roller 2 releases the fabric downwards. As the fabric moves downwards, it passes through the gap between the pressing plate 16 and the slitting machine 3 and comes between the second mounting plate 7 and the third mounting plate 9. The fabric blocks the beam of the photoelectric sensor 8. The receiving end on the third mounting plate 9 is triggered by the sudden drop in the beam, triggering a signal. According to the pre-programmed PLC, when the trigger signal is triggered, the electric cylinder 10 is started and the motor 1 is stopped. After the electric cylinder 10 is started, it pushes the push plate 15 closer to the slitting machine 3. After the push plate 15 moves toward the slitting machine 3, the pressing plate 16 first presses the fabric. On the surface of the slitting machine 3, as the pusher plate 15 continues to push, the spring 17 is compressed, so that the pressing plate 16 provides a certain pressing and fixing effect on the fabric. Then, the two wire seats 14 are inserted into the receiving cavity 11. Then, the electrothermal cutting wire 13 enters the cutting groove 12 to thermally cut the fabric between the two pressing plates 16. After cutting, the electric cylinder 10 will drive the pusher plate 15 to return to its original position. The cut fabric will fall naturally into the collection box 6 due to gravity. At this time, the photoelectric sensor 8 will resume the detection state and trigger a signal because the fabric is no longer obstructed by the falling fabric. This will send a start signal to the motor 1, allowing the motor 1 to drive the fabric to continue to be fed downwards, realizing fully automated slitting.
