Description

Technical Field

[0001] The invention relates to the technical field of cloth cutting, in particular to a laser cutting machine for processing automobile sunshade curtain cloth. Background Art

[0002] With the rapid development of the automobile industry and the continuous improvement of consumer demand, automobile interior accessories, especially automobile sunshades, have become important accessories to improve driving comfort and protect the interior decoration from damage by ultraviolet rays and high temperature. Automobile sunshades can not only effectively block direct sunlight and reduce the temperature rise in the car, but also protect seats, dashboards and other interior materials from long-term light aging. Therefore, the market demand for automobile sunshades continues to increase, and the quality and personalization requirements for sunshades are also increasing.

[0003] For example, in the prior art, a cloth laser positioning and cutting device with the publication number CN118492669A can remove wrinkles and smoothen cloth to improve the flatness of cloth before cutting. However, the above patent only uses a cloth tensioning and fixing mechanism to pull the cloth in the air and perform laser cutting while maintaining the cloth tension. This may cause the cloth to deform due to the release of tension after cutting, resulting in a deviation between the size of the cut cloth and the preset value. In addition, the edge of the cut cloth may sag during the cutting process and may come into contact with the cutting laser when it is about to be separated, causing accidental damage to the cut cloth. In view of the above technical defects, a solution is now proposed. Summary of the invention

[0004] The purpose of the present invention is to provide a laser cutting machine for processing automobile sunshade fabrics, which can not only stably adsorb and fix the sunshade fabrics, eliminating the problem of reduced cutting quality due to the tensile force on the fabrics during cutting, but also purify the generated smoke; in addition, combined with a tensioning smoothing component, while flattening and smoothing the fabric, with the help of the purified smoke flowing in the heating plate, part of the heat is taken away and enters the tensioning roller, and then discharged from the air outlet pipe, which not only reduces the temperature of the heating plate to avoid overheating and damage of the fabric, but also realizes the preheating of the fabric. At the same time, the emphasis is on strengthening the preheating of the flattened and stretched area of ​​the fabric, which helps to maintain the shape of the fabric after flattening, thereby improving the smoothing effect, so as to solve the above-mentioned technical defects.

[0020] A dust filter 23 is fixedly connected to the inside of the collection box 21. The dust filter 23 is located on a side of the collection box 21 away from the adsorption tube 22, and is used to block large particles of impurities in the flue gas and store them inside the collection box 21.

[0023] The roller 35 is rotatably connected to the inside of the lower shell 31, the heating plate 34 is fixedly connected to the inside of the lower shell 31, and a heating chamber connected to the intake pipe 24 is opened inside the heating plate 34, an electric heating net 37 is fixedly installed in the heating chamber, and a serpentine flow chamber 38 connected to the heating chamber is opened inside the heating plate 34, and the free end of the serpentine flow chamber 38 passes through the top outer side of the heating plate 34, and the purified flue gas is extracted from the collecting box 21 and injected into the serpentine flow chamber 38 in the heating plate 34 through the intake pipe 24, which can take away part of the heat on the heating plate 34 and avoid overheating of the heating plate 34 and damage to the fabric.

[0024] The pressing plate 36 is fixedly installed inside the upper shell 32 by a spring 39. During the pulling process of the car sunshade fabric, the electric heating net 37 in the heating plate 34 is energized to generate heat, thereby heating the sunshade fabric. The pressing plate 36 under the compression of the spring 39 and the heating plate 34 can smooth the fabric during movement. The two sides of the tensioning roller 4 are rotatably connected to the mounting blocks 41 fixedly connected to the upper shell 32, and the outer wall of the upper shell 32 is bolted with a motor 42 for driving the tensioning roller 4 to rotate.

[0025] Example 2: Please refer to Figure 5-Figure 11 As shown, in this embodiment, the pressing plate 36 is fixedly installed inside the upper shell 32 by a spring 39, and the two sides of the tensioning roller 4 are rotatably connected with the mounting blocks 41 fixedly connected to the upper shell 32, and the outer wall of the upper shell 32 is bolted with a motor 42 for driving the tensioning roller 4 to rotate. During the process of pulling the cloth to move, the motor 42 is started to drive the tensioning roller 4 to rotate, and the linear speed of the tensioning roller 4 is equal to the moving speed of the cloth to ensure that there is a tensile force on the car sunshade cloth during the cloth pulling process to maintain the tension of the cloth, thereby facilitating efficient smoothing processing.

[0026] A plurality of trapezoidal guide grooves 43 are equidistantly formed on the annular outer wall of the tensioning roller 4, and the plurality of trapezoidal guide grooves 43 are mirror-distributed in an "eight" shape, so as to enable a plurality of trapezoidal push blocks 47 to contact the cloth in pairs in turn, thereby gradually achieving the effect of pushing the cloth.

[0027] The guide surface of the trapezoidal guide groove 43 is provided with a convex slide groove 44, and the interior of the convex slide groove 44 is fixedly connected with a convex slider 46 through a spring 45, and the convex slider 46 is fixedly connected with a trapezoidal push block 47. The starter motor 42 drives the tensioning roller 4 to rotate. As the tensioning roller 4 rotates, multiple groups of mirror-distributed trapezoidal push blocks 47 on the tensioning roller 4 contact the cloth in pairs in sequence. Combined with the resistance of the roller 35 and the guiding action of the oblique guiding surface on the trapezoidal guide groove 43, each group of two mirror-distributed trapezoidal push blocks 47 drive the cloth to move in opposite directions and compress the corresponding spring 2 45 to flatten the folded or wrinkled cloth, thereby enhancing the effect of subsequent smoothing treatment. After the trapezoidal push block 47 is separated from the cloth, the trapezoidal push block 47 is driven to reset under the compression action of the spring 2 45, and with the continuous rotation of the tensioning roller 4, the moving cloth is repeatedly flattened uninterruptedly, and then combined with the heating plate 34 and the pressing plate 36 to achieve efficient cloth smoothing treatment.

[0028] A heat transfer cavity 48 is provided inside the tension roller 4, and a connecting groove 49 communicating with the heat transfer cavity 48 is provided at the bottom of the mounting block 41 located just above the gas outlet end of the serpentine flow cavity 38, and a sealing gasket is fixedly embedded at the bottom of the mounting block 41 on the outside of the connecting groove 49, and the sealing gasket is a high-temperature resistant sealing gasket. After the cylinder 1 33 pushes the upper shell 32 down and contacts the lower shell 31, the sealing gasket on the mounting block 41 contacts the heating plate 34, so that the serpentine flow cavity 38 is connected with the connecting groove 49 on the mounting block 41; The purified flue gas extracted from the collecting box 21 is injected into the serpentine flow cavity 38 in the heating plate 34 through the suction pipe 24, and enters the interior of the tensioning roller 4 through the connecting groove 49 on the corresponding mounting block 41 after being heated. The hot flue gas entering the tensioning roller 4 heats the tensioning roller 4, thereby preheating the entire fabric during the flattening process.

[0029] One side of the convex slider 46 is fixedly connected with an air outlet pipe 410 that is slidably connected to the tensioning roller 4, and the free end of the air outlet pipe 410 is movably extended to the inside of the heat transfer cavity 48. A plurality of air outlet holes are equidistantly provided on the air outlet pipe 410. During the movement of the trapezoidal push block 47 compressing the spring 2 45, the trapezoidal push block 47 synchronously drives the air outlet pipe 410 to enter the trapezoidal guide groove 43, so that the plurality of air outlet holes on the air outlet pipe 410 enter the trapezoidal guide groove 43. The hot flue gas in the tensioning roller 4 is blown into the trapezoidal guide groove 43 through the air outlet holes on the air outlet pipe 410 to contact the cloth, and the area after the cloth is flattened is simultaneously subjected to enhanced preheating treatment, so that the flattened cloth is not easy to rebound and recover. When the trapezoidal pushing block 47 is separated from the cloth, the trapezoidal pushing block 47 is driven to return to its original position under the compression action of the spring 2 45, and the air outlet pipe 410 is simultaneously pushed into the heat transfer cavity 48, thereby blocking the air outlet holes on the air outlet pipe 410, so as to control the hot flue gas to be discharged only at the designated position between the tensioning roller 4 and the supporting roller 35.

[0030] Example 3: Please refer to Figure 1-Figure 11 As shown, the present invention also proposes a method for using a laser cutting machine for processing automobile sunshade fabric, comprising the following steps: Step 1: Start the cylinder 1 33 to push the upper shell 32 up, drive the tension roller 4 and the roller 35, and the pressing plate 36 and the heating plate 34 to separate, then pass the sunshade fabric between the upper shell 32 and the lower shell 31, and place the end of the fabric between the movable frame 12 and the clamping plate 14, drive the clamping plate 14 to move through the cylinder 2 13, and clamp and fix the end of the fabric in combination with the anti-slip rubber block and the movable frame 12, and the cylinder 1 33 drives the upper shell 32 to descend and reset; Step 2: The electric cylinder slide module 15 drives the movable frame 12 to move away from the lower shell 31, and pulls the sunshade fabric to be laid flat on the placement screen 11 on the cutting table 1, and the electric heating net 37 in the heating plate 34 is energized to heat up, so as to heat the sunshade fabric, and the pressing plate 36 under the compression of the spring 39 and the heating plate 34 are combined to smooth the fabric during the movement; Step 3: Start the motor 42 to drive the tension roller 4 to rotate, and the linear speed of the tension roller 4 is equal to the moving speed of the cloth. As the tension roller 4 rotates, each group of two trapezoidal push blocks 47 distributed in a mirror image on the tension roller 4 synchronously contacts the cloth, and under the interference cooperation of the roller 35, each group of two trapezoidal push blocks 47 distributed in a mirror image drive the cloth to move in the opposite direction, and compress the corresponding spring 2 45 to flatten the folded or wrinkled cloth, thereby enhancing the subsequent smoothing effect. After the trapezoidal push block 47 is separated from the cloth, it resets under the compression of the spring 2 45, and then repeats the uninterrupted flattening of the moving cloth; Step 4: During the process of pulling the cloth to move, the exhaust fan 25 extracts the air in the collection box 21, first forming a negative pressure environment inside the collection box 21, and then extracts the air in the cutting table 1 through the adsorption tube 22, adsorbing and fixing the cloth placed on the screen 11, and the air extracted from the collection box 21 is injected into the serpentine flow cavity 38 in the heating plate 34 through the suction pipe 24, and then enters the tensioning roller 4 through the connecting groove 49 on the corresponding mounting block 41, taking away part of the heat on the heating plate 34, so as to prevent the heating plate 34 from overheating and causing damage to the cloth; Step 5: The hot air flow entering the tensioning roller 4 heats the tensioning roller 4, thereby preheating the fabric while flattening it. In addition, during the movement of the trapezoidal push block 47 compressing the spring 2 45, the trapezoidal push block 47 simultaneously drives the air outlet pipe 410 to enter the trapezoidal guide groove 43, and the hot air flow in the tensioning roller 4 is blown into the trapezoidal guide groove 43 through the air outlet holes on the air outlet pipe 410 to contact the fabric, and the flattened fabric is simultaneously subjected to enhanced preheating treatment, so that the flattened fabric is not easy to rebound and recover. After the trapezoidal push block 47 is reset under the action of the spring 2 45, the air outlet holes on the air outlet pipe 410 are blocked to control the hot air flow to be discharged at a designated position; Step six: After the sunshade fabric is pulled, the electric cylinder slide module three 19 drives the movable frame two 16 to move, and the electric cylinder slide module two 17 drives the laser cutting machine body 18 to move, thereby completing the cutting of fabrics of different shapes, and the smoke generated during the cutting process is extracted by the exhaust fan 25, and the particulate impurities in the smoke are stored in the collection box 21 under the obstruction of the dust removal filter 23, and the fine particulate impurities and harmful substances in the smoke are adsorbed and purified by activated carbon particles.
