Description

Technical Field

[0001] This invention belongs to the field of fire protection fabric production technology, specifically a fire protection fabric processing equipment and its processing technology. Background Technology

[0002] Fire-fighting protective fabrics are the core basic materials for fire safety protective equipment, widely used in the production of various protective products such as fire-fighting suits, heat-insulating protective clothing, and rescue clothing. With the continuous upgrading of fire safety industry standards, the market is demanding higher standards for the flame retardancy, heat insulation, temperature resistance, fire resistance, mechanical strength, and user comfort of fire-fighting fabrics. Currently, the industry mostly uses materials such as chemical fiber blends and aramid composites to weave fire-fighting base fabrics. Standardized weaving equipment is used to complete the fabric weaving process, forming neat rolls of fabric that facilitate subsequent transportation, storage, and mass production. This is a crucial preliminary step in the industrialization of fire-fighting apparel production.

[0003] The fabric deep-processing industry system is becoming increasingly complete. Mainstream processing methods can complete a series of conventional treatment processes such as flame-retardant impregnation, coating, lamination, and drying, stably imparting basic protective functions to the fabric. Meanwhile, the application scope of recycled and environmentally friendly fabrics continues to expand. Recycled PET fabrics, with their advantages of low carbon emissions, environmental friendliness, readily available raw materials, and excellent weaving performance, are gradually being integrated into the fire protection fabric production field, gradually replacing some traditional chemical fiber fabrics. While meeting basic usage needs, they align with the concept of green production development, becoming one of the mainstream development directions in the fire protection fabric production field.

[0004] However, the existing fabric winding and cutting process has a simple structure. Long-sized fabrics require large clamping devices, which occupy a lot of space. The manual material pulling operation is cumbersome and inefficient, affecting the quality of subsequent deep processing. Summary of the Invention

[0005] The purpose of this invention is to address the problems mentioned above, such as the simple structure of existing fabric winding and cutting processes, the need for large clamping devices for cutting long fabrics, the large space occupation, the cumbersome and inefficient manual material pulling operation, and the impact on the quality of subsequent deep processing. This invention provides a fire protection fabric processing equipment and its processing technology.

[0006] The technical solution adopted in this invention is as follows: a fire-fighting fabric processing equipment includes a support base, side plates are provided on both sides of the support base, a feeding device is installed between one end of the side plates, a cutting device is installed between the upper ends of the side plates, a second groove is opened at the upper and lower ends of one side inner wall of the side plate, a lead screw device is installed inside the second groove, a clamping and folding device is provided on one side of the lead screw device, a folding frame is provided on the surface of the support base, a first groove is opened on both sides of the two ends of the folding frame, the lead screw device is installed inside the first groove, and a pressure plate device is provided on one side of the lead screw device.

[0007] By adopting the above technical solution, the clamping and folding device integrates clamping, winding and pulling functions, and achieves precise displacement with the screw device. It does not require a large clamping device, and the equipment has a compact structure, occupies little space, and is suitable for the cutting needs of long-size fabrics.

[0008] In a preferred embodiment, the feeding device includes a motor, which is installed inside the side plate. A mounting plate is provided on one side of the motor, and fixing plates are provided at both ends of the mounting plate. A feeding roller is provided on one side of the fixing plate.

[0009] By adopting the above technical solution, the motor is fixed inside the side plate and drives the mounting plate to rotate. The mounting plate is symmetrically set with fixing plates at both ends for installing two sets of feeding rollers respectively. It can load two rolls of fire protection fabric at the same time. When the fabric on one set of feeding rollers is exhausted, the motor drives the mounting plate to rotate quickly to switch to the other set of feeding rollers. There is no need to stop the machine to change rolls, which effectively improves the efficiency of continuous operation.

[0010] In a preferred embodiment, the clamping and folding device includes a movable mounting plate, a slide rail is provided on one side surface of the movable mounting plate, a lead screw device is installed inside the slide rail, a mounting block is provided on one side of the lead screw device, a servo motor is installed inside the mounting block, a connecting block is provided on one side of the servo motor, a three-way groove is provided on one side surface of the connecting block, a bidirectional lead screw device is installed inside the three-way groove, and semi-circular clamping plates are provided at both ends of the bidirectional lead screw device.

[0011] By adopting the above technical solution, the movable mounting plate moves up and down along the side plate slide rail through the screw device, driving the entire clamping and folding device to rise and fall. The servo motor is installed in the mounting block and can drive the connecting block to rotate, so that the semi-circular clamping plate rotates to wind the fabric. The bidirectional screw device drives the two semi-circular clamping plates at both ends to open and close synchronously in the slide groove three, so as to achieve stable clamping of the fabric ends and provide a reliable clamping foundation for pulling, cutting and folding.

[0012] In a preferred embodiment, the lead screw device includes a lead screw motor, a lead screw is provided on one side of the lead screw motor, a movable block is threadedly connected to the outer surface of the lead screw, and a movable mounting plate, the mounting block, or the pressure plate device is provided on one side of the movable block.

[0013] By adopting the above technical solution, the lead screw motor outputs power to drive the lead screw to rotate. The lead screw drives the moving block to move precisely along the axial direction through the thread transmission. The moving block is connected to the moving mounting plate, mounting block or pressure plate device according to the installation position, so as to realize the lifting, horizontal movement of the clamping and folding device and the translation of the pressure plate device. The transmission accuracy is high and the response speed is fast, which meets the needs of precise action in multiple workstations.

[0014] In a preferred embodiment, sliders are provided on both sides of the movable block, and a limit rod is slidably connected inside the slider.

[0015] By adopting the above technical solution, when the lead screw rotates, the limiting slide bar restricts the moving block from rotating with the lead screw, so that the moving block only makes linear motion, avoiding running jams and deviations, and improving the stability and reliability of the movement process.

[0016] In a preferred embodiment, the bidirectional lead screw device includes a bidirectional lead screw motor, a bidirectional lead screw is provided on one side of the bidirectional lead screw motor, movable sliders are threaded to the outer surfaces of both ends of the bidirectional lead screw, and a semi-circular clamp is provided on one side of the movable slider.

[0017] By adopting the above technical solution, the bidirectional lead screw motor drives the bidirectional lead screw to rotate. The threads at both ends of the bidirectional lead screw rotate in opposite directions, which can drive the moving sliders at both ends to move synchronously in opposite directions, so as to realize the rapid and synchronous opening and closing of the semi-circular clamping plate, the uniform clamping force, and ensure that the fabric is firmly clamped and the force is even, preventing the fabric from being pinched or slipping.

[0018] In a preferred embodiment, a limiting groove is formed on the inner wall of the sliding groove three, and a limiting slider corresponding to the limiting groove is provided on one side of the movable slider, and the limiting slider is slidably connected inside the limiting groove.

[0019] By adopting the above technical solution, the moving slider is restricted from rotating with the bidirectional lead screw, ensuring that the semi-circular clamping plate only performs linear opening and closing movements along the slide groove, avoiding skewed movements, and further improving clamping stability and positioning accuracy.

[0020] In a preferred embodiment, the pressure plate device includes a connecting plate, a reduction motor is installed inside the lower end of the connecting plate, and a folding pressure plate corresponding to the connecting plate is provided on one side of the reduction motor.

[0021] By adopting the above technical solution, the geared motor drives the folding pressure plate to rotate. When the folding pressure plate rotates and presses down, it can accurately press the folding part of the flat material and complete the folding action. When it rotates and lifts up, it releases the fixation. In conjunction with the clamping folding device, it can realize multi-layer cyclic folding, ensuring neat folding and flat fabric.

[0022] In a preferred embodiment, the outer surface of the semi-circular clamp is coated with an anti-slip coating.

[0023] By adopting the above technical solution, the anti-slip coating can significantly increase the friction between the anti-slip coating and the fire protection fabric, improve the clamping stability, prevent the fabric from slipping during the pulling and winding process, adapt to the clamping needs of fire protection fabrics of different thicknesses and materials, and has strong versatility.

[0024] In a preferred embodiment, the steps are as follows:

[0025] S1. The two rolls of fire-fighting fabric are respectively installed on the two sets of feeding rollers of the feeding device. The two sets of feeding rollers are fixed by the mounting plate and the fixing plate. The feeding rollers can be quickly switched as the mounting plate rotates. When one set of fabric is exhausted, it is immediately switched to the other set.

[0026] S2. Pass the fabric through the clamping and folding device. The bidirectional lead screw device drives the semi-circular clamping plate to close and clamp the end of the fabric. Start the servo motor to drive the connecting block to rotate, so that the fabric is gradually wrapped around the outer surface of the semi-circular clamping plate, realizing the smooth pulling and feeding of the fabric. After the fabric is pulled to the set length, the cutting device cuts the fabric.

[0027] S3. The lead screw device drives the clamping and folding device and the semi-circular clamping plate to move downwards, placing one end of the fabric inside the folding frame; the reduction motor drives the folding pressure plate to rotate and press down, squeezing and fixing the end of the fabric; then the lead screw device drives the semi-circular clamping plate to move back and forth along the surface of the folding frame. Each time it moves to the position of the folding pressure plate, the folding pressure plate first releases the squeezing, the semi-circular clamping plate releases the fabric and completes one layer of folding, and the folding pressure plate presses down again to fix a new layer of fabric; this cycle is repeated to complete the neat folding of the entire fabric.

[0028] S4. After folding, all devices are reset, the feeding roller is switched or the next round of operation is started directly, and the fabric feeding, cutting and folding processes are repeated.

[0029] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0030] 1. The clamping and folding device integrates clamping, winding, and pulling functions, and works with the lead screw device to achieve precise displacement. It does not require a large clamping device, and the equipment has a compact structure and occupies little space, making it suitable for the cutting needs of long-size fabrics.

[0031] 2. With the dual feed roller quick switching structure, one set of fabric can be switched to another immediately when the first set is exhausted, without stopping the machine to change rolls, which greatly improves the efficiency of continuous processing and solves the problems of machine stoppage and low efficiency when changing materials in traditional equipment.

[0032] 3. The folding pressure plate can be rotated down to fix and lifted to release. Combined with the reciprocating movement of the semi-circular clamping plate, it achieves automatic multi-layer folding of the fabric, precisely flattening the folds to ensure neat folds and a flat fabric, preventing wrinkles from affecting the quality of subsequent deep processing.
