Description

Technical Field

[0001] The invention relates to the technical field of laser hot cutting equipment, in particular to a multi-specification laser hot cutting device for producing chemical fiber cloth. Background Art

[0002] Chemical fiber fabrics are new types of clothing developed in modern times, and there are many types. Here it mainly refers to pure, blended or interwoven fabrics processed from chemical fibers, that is, fabrics woven from pure chemical fibers. Chemical fiber fabric laser cutting machines are specially designed for the garment industry and the cutting and production of plush chemical fiber fabrics. They can accurately cut a variety of clothing fabrics into any pattern, and can be equipped with a feeding device to achieve continuous and automatic cutting of coiled materials, completely replacing the ancient electric ironing process.

[0003] For example, a laser cutting device for chemical fiber cloth production with announcement number CN210908567U comprises a chassis, a placement slot is provided at the upper middle position of the chassis, a cloth placement table is arranged inside the placement slot, T-shaped sliders are arranged on the left and right sides of the cloth placement table, T-shaped slide grooves are provided inside the chassis at positions corresponding to the T-shaped sliders, a fixing plate is arranged at the rear end of the cloth placement table, and fixing rods are arranged on the left and right sides of the rear end of the fixing plate at positions corresponding to the fixing plate. By arranging structures such as the cloth placement table, T-shaped slider, T-shaped slide groove, fixing rod, threaded cap, cylinder, cylinder shaft and fixing plate, the cloth placement table can be mechanically pushed out to facilitate the placement and removal of chemical fiber cloth through the mutual cooperation of these structures. The cloth placement table is easy to disassemble and can be replaced regularly to ensure the working efficiency of the device, mechanical operation, high degree of automation and strong practicality.

[0004] Although the above patent makes it easy to take chemical fiber fabrics in time, chemical fiber fabrics themselves are prone to wrinkles and difficult to recover. Fabrics of different thicknesses and specifications have different degrees of wrinkles. Repeatedly taking and placing chemical fiber fabrics further aggravates the generation of such wrinkles. If the laser head directly cuts on the wrinkled chemical fiber fabric, it is easy to cause the cutting surface to be unsmooth and incomplete, affecting the effect of the finished product after cutting.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The inclined portion is the winding end of the chemical fiber cloth. The chemical fiber cloth naturally droops to ensure the flatness of the chemical fiber cloth. During the downward movement of the laser head, the airbag first contacts the chemical fiber cloth, and the airflow inside the airbag is ejected from the air jet port to blow away the dust on the surface of the chemical fiber cloth and take away the heat on the surface. The airbag slides on the surface of the chemical fiber cloth to locally flatten the chemical fiber cloth before and after cutting. One end of the chemical fiber cloth is connected to the winding mechanism, and the continuous winding of the winding mechanism further ensures the overall flatness of the chemical fiber cloth. It is suitable for a variety of specifications and solves the problem that the laser head mentioned in the background technology is used to cut on the wrinkled chemical fiber cloth, which easily leads to an unsmooth and incomplete cutting surface.

[0024] 2. After the motor is turned on, the first gear, the inner gear ring, the protective cover, and the airbag rotate in sequence, and the flattening position can be adjusted rotatably, further increasing the flatness of the chemical fiber fabric.

[0025] 3. During the movement of the airbag, the arc plate and the heat conduction plate move synchronously. When the chemical fiber fabric is wrinkled and arched, the moving heat conduction plate flattens the arched part, and the second elastic member adaptively expands and contracts to flatten the part of the chemical fiber fabric, which has a good use effect.

[0026] 4. The chemical fiber fabric is wound on the winding roller. After the laser head completes the partial heat cutting, the driving mechanism drives the first pulley and the winding roller to rotate, and the chemical fiber fabric can be wound as a whole. One end of the chemical fiber fabric is applied with overall force to ensure the overall longitudinal flatness of the chemical fiber fabric.

[0027] 5. When the winding roller is rotating, the eccentric cam can rotate. When one of the eccentric cams contacts the chemical fiber cloth, the outer end of the chemical fiber cloth can be stretched outward, and the entire chemical fiber cloth can be flattened laterally. When the other eccentric cam contacts the chemical fiber cloth, other areas of the chemical fiber cloth can be stretched, further ensuring the flatness of the chemical fiber cloth and good hot cutting effect.

[0028] 6. During the hot cutting process of chemical fiber fabrics, the arc plate on the periphery of the laser head can be used to flatten the chemical fiber fabric locally. The eccentric cam and the winding roller can be used to flatten the chemical fiber fabric as a whole. Multiple methods can be used to cooperate without manual control, which effectively reduces the occurrence of wrinkles on the chemical fiber fabric and ensures the effect of the finished product.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1: Please refer to Figure 1-Figure 7 The present invention provides a technical solution: a multi-specification laser hot cutting device for chemical fiber cloth production, comprising an operating table mechanism 1, a hot cutting mechanism 2 is arranged on the upper end of the operating table mechanism 1, and a chemical fiber cloth 3 is laid on the upper end of the operating table mechanism 1. The chemical fiber cloth 3 is made of chemical fiber material. When it is laid flat on the operating table mechanism 1, the hot cutting mechanism 2 can be used to cut the chemical fiber cloth 3 into a specific shape.

[0040] The operating table mechanism 1 comprises an operating table body 11 and an inclined portion 12 on one side of the operating table body 11 . The inclined portion 12 is the winding end of the chemical fiber cloth 3 . The chemical fiber cloth 3 droops naturally, thereby ensuring the flatness of the chemical fiber cloth 3 .

[0041] The hot cutting mechanism 2 includes a mounting member 21 and an extension rod 22 mounted at the lower end of the mounting member 21. The extension rod 22 is a telescopic rod structure that can be extended and retracted. A laser head 23 is provided at the lower end of the extension rod 22. The laser head 23 faces the chemical fiber fabric 3. A slide groove 24 is provided on the outer periphery of the extension rod 22.

[0042] A protective mechanism 4 is arranged on the periphery of the hot cutting mechanism 2, and the protective mechanism 4 includes a protective cover 41 arranged on the periphery of the extension rod 22. The protective cover 41 is slidably installed on the periphery of the extension rod 22, and an air bag 43 is fixedly installed on the lower end of the protective cover 41. The periphery of the air bag 43 is provided with a jet port 44.

[0043] When the chemical fiber fabric 3 needs to be cut, the laser head 23 needs to be extended first and brought close to the chemical fiber fabric 3, and then moved forward, backward, left and right according to the shape that the chemical fiber fabric 3 needs to be cut into, until the laser head 23 completes the cutting of the chemical fiber fabric 3.

[0044] During the downward movement of the laser head 23, the airbag 43 first contacts the chemical fiber cloth 3, and the airbag 43 is squeezed upward, and the airflow inside the airbag 43 is ejected from the air jet port 44 to blow away the dust on the surface of the chemical fiber cloth 3 and take away the heat on the surface. During the movement of the laser head 23, the airbag 43 moves together, and the heat of the hot-cut part can be dissipated at any time. The airbag 43 slides from the surface of the chemical fiber cloth 3 to level the chemical fiber cloth 3 before and after cutting, and the hot cutting effect is good.

[0045] By setting the protective cover 41, the upward moving distance of the protective cover 41 is limited, and the height of the laser head 23 can be limited to prevent the height of the laser head 23 from being too low, which will cause the chemical fiber cloth 3 to be heated too high, thereby affecting the integrity of the hot cutting and local yellowing. One side of the protective cover 41 is connected to an absorption tube 411, and one side of the absorption tube 411 is connected to an air pump. After the air pump is turned on, the absorption tube 411 generates suction, which can absorb the smoke inside the protective cover 41, preventing the smoke from remaining on the chemical fiber cloth 3 and causing the chemical fiber cloth 3 to turn yellow, and the protective effect is good.

[0046] A winding mechanism 5 is installed on one side of the operating table mechanism 1 , and one end of the chemical fiber cloth 3 is connected to the winding mechanism 5 . The continuous winding of the winding mechanism 5 further ensures the flatness of the chemical fiber cloth 3 .

[0047] A guide mechanism 7 is also provided inside the airbag 43 .

[0048] Example 2: Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 The operating table mechanism 1 also includes two slide rails 13, which are fixedly mounted on both sides of the operating table body 11 and the inclined portion 12, respectively. A guide rail frame 14 is slidably mounted on the two slide rails 13. Both ends of the guide rail frame 14 slide in the slide rails 13, and the longitudinal position of the laser head 23 can be adjusted. The mounting member 21 of the hot cutting mechanism 2 is slidably mounted on the lower end of the guide rail frame 14, and the lateral position of the laser head 23 can be adjusted, which can adapt to the cutting of chemical fiber fabrics 3 of various specifications and types.

[0049] A top plate 25 is slidably mounted on the outer periphery of the mounting member 21, and the top plate 25 is rotatably mounted on the inner wall of the protective cover 41. A fixing block 42 is installed between the protective cover 41 and the airbag 43. Two baffles 45 are fixedly mounted on the inner wall of the protective cover 41. The inner walls of the baffles 45 are matched with the slide groove 24, and an inner gear ring 46 is fixedly mounted inside the two baffles 45.

[0050] A first elastic member 47 is installed on the upper end of the baffle 45 and the lower end of the mounting member 21 . A first gear 48 is meshedly installed on one side of the inner gear ring 46 . A motor 49 is installed on the upper end of the first gear 48 . The motor 49 is fixedly installed on the inner wall of the top plate 25 .

[0051] When the airbag 43 is squeezed to the maximum distance, the protective cover 41 and the top plate 25 can move straight upward, and the first elastic member 47 is compressed. It can be adaptively adjusted according to the chemical fiber fabrics 3 of different thicknesses and softness, and can completely cover the laser head 23. Through the reaction force of the first elastic member 47, after the laser head 23 is reset, the protective cover 41 can be reset together.

[0052] After the motor 49 is turned on, the first gear 48 , the inner gear ring 46 , the protective cover 41 , and the airbag 43 rotate in sequence, and the flattening position can be rotatably adjusted, further increasing the flatness of the chemical fiber fabric 3 .

[0053] Example 3: Please refer to Figure 1 , Figure 5-Figure 7 The guide mechanism 7 includes an inner cylinder 71 fixedly mounted on the top wall of the airbag 43, an extrusion rod 72 is slidably mounted inside the inner cylinder 71, a push rod 73 is fixedly mounted on the lower end of the extrusion rod 72, a top plate 74 is fixedly mounted on the lower end of the push rod 73, and the top plate 74 is mounted on the bottom wall of the airbag 43. An air pipe 75 is installed on the outer periphery of the inner cylinder 71, and the air pipe 75 is connected to the jet port 44.

[0054] The inner cylinder 71 is filled with gas. When the airbag 43 contacts and compresses the chemical fiber cloth 3, the top plate 74, the push rod 73, and the extrusion rod 72 move upward. The extrusion rod 72 is a piston head structure. When it moves upward, the gas inside the inner cylinder 71 can be discharged from the air pipe 75 and ejected from the air jet 44. The air jet 44 has a small diameter and a high air circulation rate, which can remove dust and cool the chemical fiber cloth 3. When the laser head 23 is reset, the airbag 43, the top plate 74, and the extrusion rod 72 are reset, and negative pressure is generated inside the inner cylinder 71, which can re-inhale the gas into the inner cylinder 71, thereby ensuring the continuity of the mechanism's operation.

[0055] A pushing mechanism 8 is arranged on the periphery of the protection mechanism 4. The pushing mechanism 8 includes an arc plate 81 rotatably mounted on both sides of the airbag 43. A heat conducting plate 82 is fixedly mounted on the lower end of the arc plate 81. A second elastic member 83 is installed between the arc plate 81 and the airbag 43.

[0056] During the movement of the airbag 43, the arc plate 81 and the heat conducting plate 82 move synchronously. When the chemical fiber fabric 3 is wrinkled and arched, the moving heat conducting plate 82 flattens the arched part, and the second elastic member 83 adaptively expands and contracts to flatten part of the chemical fiber fabric 3, resulting in good use effect.

[0057] Example 4: Please refer to Figure 1-Figure 4 The winding mechanism 5 includes a mounting block 51 fixedly mounted on one end of the slide rail 13, a groove 52 is provided at the upper end of the mounting block 51, a winding roller 53 is mounted on the mounting block 51, the winding roller 53 is fixed by the mounting block 51, a first pulley 54 is fixedly mounted on one end of the winding roller 53, the first pulley 54 is externally connected to a driving mechanism, the chemical fiber fabric 3 is wound around the winding roller 53, after the laser head 23 completes partial hot cutting, the driving mechanism drives the first pulley 54 and the winding roller 53 to rotate, and the chemical fiber fabric 3 can be wound as a whole, and one end of the chemical fiber fabric 3 is applied with overall force to ensure the overall longitudinal flatness of the chemical fiber fabric 3.

[0058] A limiting cylinder 55 is fixedly mounted on one end of the mounting block 51. The limiting cylinder 55 is a semicircular structure and is arranged on the periphery of the winding roller 53. That is, both sides of the chemical fiber fabric 3 are wound in the limiting cylinder 55, which greatly prevents the chemical fiber fabric 3 from being deformed twice.

[0059] Example 5: Please refer to Figure 1-Figure 4 , Figure 8 A first bevel gear 56 is also fixedly mounted on the winding roller 53 .

[0060] A straightening mechanism 6 is provided on both sides of the winding mechanism 5. The straightening mechanism 6 includes a fixed rod 61 fixedly installed on both sides of the operating table mechanism 1. A rotating shaft 62 is fixedly installed on the fixed rod 61. Three eccentric cams 63 are fixedly installed on the rotating shaft 62. The three eccentric cams 63 rotate in different directions.

[0061] A belt body 64 is rotatably mounted on one end of the rotating shaft 62, a second pulley 65 is rotatably mounted on one end of the belt body 64, a connecting shaft 66 is fixedly mounted on one end of the second pulley 65, a second bevel gear 67 is fixedly mounted on one end of the connecting shaft 66, and the second bevel gear 67 is meshingly connected to the first bevel gear 56.

[0062] During the rotation of the winding roller 53, the first bevel gear 56, the second bevel gear 67, the connecting shaft 66, the second pulley 65, the belt body 64, the rotating shaft 62, and the eccentric cam 63 rotate in sequence. The eccentric cam 63 is eccentrically set, and the area with the longest diameter can contact the chemical fiber cloth 3. When one of the eccentric cams 63 contacts the chemical fiber cloth 3, the outer end of the chemical fiber cloth 3 can be stretched outward, and the chemical fiber cloth 3 can be flattened horizontally as a whole. When the other eccentric cam 63 contacts the chemical fiber cloth 3, other areas of the chemical fiber cloth 3 can be stretched, further ensuring the flatness of the chemical fiber cloth 3 and a good hot cutting effect.

[0063] During the hot cutting process of the chemical fiber cloth 3, the curved plate 81 on the periphery of the laser head 23 can be used to locally smooth the chemical fiber cloth 3. The cooperation of the eccentric cam 63 and the winding roller 53 can smooth the chemical fiber cloth 3 as a whole. Multiple methods can be coordinated without manual control, which effectively reduces the occurrence of wrinkles on the chemical fiber cloth 3 and ensures the finished product effect.
