[0002] In the production process of automotive nonwoven fabrics, in order to give them the required shape and properties so that they can be used in the production of automotive interiors, seats and other parts, a stretching and setting device is needed to stretch and set the automotive nonwoven fabrics.

[0003] Chinese patent CN 217781485 U discloses a stretching and setting modification device for automotive nonwoven fabric production, including a machine body, an air outlet plate, and a support plate. The air outlet plate and an adjusting plate are installed on the inner wall of the machine body. A motor is installed on the inner wall of the machine body, and a roller is installed at the output end of the motor. A spring is installed on the outer wall of the support plate, and a baffle is installed at one end of the spring. A connecting rope is installed on the outer wall of the roller. This invention, by installing the roller, adjusting plate, and baffle, allows for rapid airflow adjustment. When increased airflow is needed, the motor rotates, moving the baffle and reducing the area of ​​the adjusting plate blocked by the baffle at the opening, thus increasing the output airflow. The air outlet plate has evenly distributed air outlets. When reduced airflow is needed, the motor reverses. This structure allows for rapid airflow adjustment, facilitating control of the drying effect according to requirements, thereby improving the stretching and setting modification effect.

[0004] Existing stretching and setting devices cannot adjust the tension of automotive nonwoven fabrics in a timely manner during the stretching and setting process, which easily leads to wrinkles in the nonwoven fabrics and results in poor efficiency in adjusting the tension of automotive nonwoven fabrics. Therefore, a stretching and setting device for automotive nonwoven fabrics is proposed to address the above problems. Summary of the Invention

A lead screw is mounted on the output shaft of the stepper motor, and the lead screw is rotatably mounted on the inner wall of the lifting groove. A detection block is mounted on one of the lifting blocks, and an indicator light is mounted on the detection block. A sliding groove is formed within the detection block, and a slider is assembled within the sliding groove. A first electrode plate is mounted on the bottom side of the slider, and a second electrode plate is mounted on the inner wall of the sliding groove.

A setting machine is installed on the base, and a control panel is installed on the outer wall of the setting machine. The control panel is connected to the second electrode plate and a stepper motor through an internal circuit. When the automotive nonwoven fabric becomes loose, the detection block drives the slider on it to move vertically downward. The slider drives the adjusting roller to move vertically downward, applying downward pressure to the automotive nonwoven fabric, so that the automotive nonwoven fabric is adjusted to a tensioned state. This structure can automatically detect the tension of the automotive nonwoven fabric and can adjust the automotive nonwoven fabric in a timely manner to avoid wrinkles in the automotive nonwoven fabric, which is beneficial to improving the efficiency of adjusting the tension of the automotive nonwoven fabric.

[0018] 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 scope of protection of the present utility model.

[0019] Please see Figure 1-3As shown, a nonwoven fabric stretcher shaping device for automobiles includes a base 1. Two sets of guide plates 2 are symmetrically mounted on the base 1. Lifting grooves 3 are formed within the guide plates 2, and lifting blocks 4 are assembled within the lifting grooves 3. A stepper motor 5 is mounted on one of the guide plates 2 via a base. A lead screw 6 is mounted on the output shaft of the stepper motor 5 and rotatably mounted on the inner wall of the lifting groove 3. A detection block 7 is mounted on one of the lifting blocks 4, and an indicator light 8 is mounted on the detection block 7. A sliding groove 9 is formed within the detection block 7, and a slider 10 is assembled within the sliding groove 9. A first electrode plate 11 is mounted on the bottom side of the slider 10, and a second electrode plate 12 is mounted on the inner wall of the sliding groove 9. An adjusting roller 33 is rotatably mounted on the slider 10, and the other end of the adjusting roller 33 is rotatably connected to the other lifting block 4. The first electrode 11 and the second electrode 12 are connected to the indicator light 8 via an internal circuit. A stenter 13 is mounted on the base 1, and a control panel 14 is mounted on the outer wall of the stenter 13. The control panel 14 is connected to the second electrode 12 and the stepper motor 5 via an internal circuit. During operation, the existing stenter 13 cannot adjust the tension of the automotive nonwoven fabric in a timely manner during the stretching and stenting process, which easily causes wrinkles in the automotive nonwoven fabric and results in poor efficiency in adjusting the tension of the automotive nonwoven fabric. The first drive motor and the second drive motor drive the release roller 20 and the take-up roller 22 to rotate synchronously. The release roller 20 releases the automotive nonwoven fabric, and the take-up roller 22 stretches and stents the automotive nonwoven fabric. During the winding process, the automotive nonwoven fabric passes sequentially through the first guide roller 23, the adjusting roller 33, the second guide roller 24, the setting machine 13, and the third guide roller 25 for stretching and shaping. When the automotive nonwoven fabric becomes loose, the nonwoven fabric in close contact with the adjusting roller 33 will fall downwards. The nonwoven fabric can no longer provide upward support to the adjusting roller 33. At this time, under its own weight, the adjusting roller 33 drives the slider 10 to move downwards in the slide groove 9, causing the first electrode plate 11 to contact the second electrode plate 12. At this time, the internal circuit of the indicator light 8 is connected, and the indicator light 8 sends an electrical signal to the control panel 14. After receiving the electrical signal, the control panel 14 controls the stepper motor 5 to operate. The stepper motor 5 drives the lead screw 6 to rotate, and the lead screw 6 drives the detection block 7 on it to move vertically. The detection block 7 moves downward, causing the slider 10 on it to move vertically downward. The slider 10 then causes the adjusting roller 33 to move vertically downward, applying downward pressure to the automotive nonwoven fabric and adjusting it to a tensioned state. At the moment the automotive nonwoven fabric is in a tensioned state, it applies an upward supporting force to the adjusting roller 33, stopping the roller 33 and causing the first electrode plate 11 and the second electrode plate 12 to separate instantly. The control panel 14 cannot receive an electrical signal, and at this time, the control panel 14 will control the stepper motor 5 to stop operating. This structure can automatically detect the tension of the automotive nonwoven fabric and adjust it in a timely manner to avoid wrinkles and improve the efficiency of adjusting the tension of the automotive nonwoven fabric.

[0020] Please see Figure 4-5 As shown, a support frame 15 is mounted on the base 1, a guide rod 16 is rotatably mounted on the support frame 15, multiple fixed seats 17 are mounted on the support frame 15, and positioning wheels 18 are rotatably mounted on the fixed seats 17. A first support seat 19 is mounted on the base 1, and a first drive motor is mounted on the first support seat 19 via a machine base. A release roller 20 is mounted on the output shaft of the first drive motor. A second support seat 21 is mounted on the base 1, and a second drive motor is mounted on the second support seat 21 via a machine base. A winding mechanism is mounted on the output shaft of the second drive motor. Roller 22, a first guide roller 23, a second guide roller 24, and a third guide roller 25 are rotatably mounted on the base 1 via a mounting bracket. The stenter 13 has an internal channel and symmetrically arranged cavities 26. Two sets of heating plates 27 with a mesh structure are installed on the inner wall of the cavities 26. Multiple exhaust holes 28 are opened on the top and bottom sides of the channel. An air guide box 29 is mounted on the base plate of the stenter 13. A fan 30 is mounted on the air guide box 29 via a base. An exhaust pipe 31 is mounted on the fan 30, and the other end of the exhaust pipe 31 connects to the air guide box. The air guide box 29 is connected, and an air guide pipe 32 is installed on the air guide box 29. The other end of the air guide pipe 32 is connected to the cavity 26. During operation, the existing stretching and shaping device cannot provide stable support for the automotive nonwoven fabric during the stretching and shaping process, resulting in poor stability of the automotive nonwoven fabric. The automotive nonwoven fabric is released by the release roller 20. Then, the automotive nonwoven fabric passes through the first guide roller 23, the adjusting roller 33 and the second guide roller 24 in sequence. After that, the automotive nonwoven fabric moves to the guide rod 16 and is located between the guide rod 16 and the positioning wheel 18. In between, the nonwoven fabric for automobiles is supported and flattened. Then, the nonwoven fabric enters the channel of the shaping machine 13. The blower 30 operates and introduces cold air into the air box 29 through the exhaust pipe 31. Then, the cold air enters the cavity 26 through the air guide pipe 32 and is heated into hot air by the heating plate 27. The hot air is then discharged from multiple exhaust holes 28, heating the flat nonwoven fabric and achieving heating and shaping of the nonwoven fabric. This structure can provide stable support for the nonwoven fabric and is beneficial to improving the stability of the nonwoven fabric.

[0021] Working principle: Existing stenter devices cannot adjust the tension of automotive nonwoven fabrics in a timely manner during the stretching and shaping process, easily causing wrinkles in the nonwoven fabric and resulting in poor efficiency in adjusting the tension. Through the operation of the first and second drive motors, the release roller 20 and the take-up roller 22 rotate synchronously. The release roller 20 releases the automotive nonwoven fabric, and the take-up roller 22 takes it back. During this process, the automotive nonwoven fabric sequentially passes through the first guide roller 23, the adjusting roller 33, the second guide roller 24, the stenter 13, and the third guide roller 25 for stretching and shaping. When the automotive nonwoven fabric becomes loose, the nonwoven fabric in close contact with the adjusting roller 33 will... As the nonwoven fabric falls, it can no longer provide upward support to the adjusting roller 33. At this point, under its own weight, the adjusting roller 33 causes the slider 10 to move downwards within the groove 9, bringing the first electrode 11 into contact with the second electrode 12. Simultaneously, the internal circuit of the indicator light 8 is activated, sending an electrical signal to the control panel 14. Upon receiving the signal, the control panel 14 controls the stepper motor 5 to operate. The stepper motor 5 drives the lead screw 6 to rotate, which in turn moves the detection block 7 vertically downwards. The detection block 7 then moves the slider 10 vertically downwards, which in turn moves the adjusting roller 33 vertically downwards, applying downward pressure to the automotive nonwoven fabric and adjusting it to a taut state. When the automotive nonwoven fabric is taut... In the instant of the state change, the automotive nonwoven fabric applies an upward supporting force to the adjusting roller 33, which stops the adjusting roller 33, causing the first electrode plate 11 and the second electrode plate 12 to separate instantaneously. The control panel 14 cannot receive an electrical signal at this time, and the control panel 14 will control the stepper motor 5 to stop operating. This structure can automatically detect the tension of the automotive nonwoven fabric and adjust it in a timely manner to prevent wrinkles and improve the efficiency of adjusting the tension of the automotive nonwoven fabric. Existing tenter frame devices cannot provide stable support for the automotive nonwoven fabric during the stretching and shaping process, resulting in poor stability. The release roller 20 releases the automotive nonwoven fabric, and then... The nonwoven fabric passes sequentially around the first guide roller 23, the adjusting roller 33, and the second guide roller 24. Then, the nonwoven fabric moves onto the guide rod 16 and is positioned between the guide rod 16 and the positioning wheel 18, thus supporting and flattening the nonwoven fabric. The nonwoven fabric then enters the channel of the setting machine 13. The blower 30 operates and introduces cold air into the air box 29 through the exhaust pipe 31. The cold air then enters the cavity 26 through the air guide pipe 32 and is heated into hot air by the heating plate 27. The hot air is then discharged from multiple exhaust holes 28, heating the flat nonwoven fabric and achieving heating and setting of the nonwoven fabric. This structure can provide stable support for the nonwoven fabric and is beneficial to improving its stability.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
