Technical Field
[0001] This utility model relates to the field of nonwoven fabric production technology, and in particular to a hot pressing and shaping device for polyester needle-punched nonwoven fabric. Background Technology
[0002] Polyester needle-punched nonwoven fabric is a type of nonwoven fabric made from polyester and polypropylene raw materials. It is produced through multiple needle punching processes and appropriate hot pressing. Depending on the different processes and materials used, tens of thousands of products can be manufactured, applicable to various industries. Various specifications of products can be customized according to different uses.
[0003] However, the existing hot pressing and shaping devices for polyester needle-punched nonwoven fabrics have some drawbacks. They are not suitable for uniform and comprehensive hot pressing of the nonwoven fabric, which can easily deform and change the shape of the nonwoven fabric. Furthermore, it is not convenient to cool and shape the nonwoven fabric in time after hot pressing. Due to the lack of timely cooling and the transmission action, the nonwoven fabric is prone to secondary deformation. Therefore, we propose a hot pressing and shaping device for polyester needle-punched nonwoven fabrics to solve the above problems. Utility Model Content

[0008] As a preferred embodiment of this utility model, two telescopic rods are fixedly connected between the connecting plate and the mounting frame, and the electric push rod is located between the two telescopic rods.
[0009] As a preferred embodiment of this utility model, a guide plate is fixedly connected between the two support plates, and a sliding sleeve is slidably fitted on the outer side of the guide plate, the sliding sleeve being fixedly connected to the top of the mounting block.

A cold air blower is fixedly connected to one side of the sealing cover. Each of the four hollow tubes has a gear two fixedly connected to its rear end. A drive column is fixedly connected to the rear side of the gear one. A frame is slidably fitted on the outer side of the drive column. A rack is fixedly connected to the side of each of the two frames that are far apart from each other. The two racks mesh with the corresponding gear two.
[0011] As a preferred embodiment of this utility model, four fixing plates are fixedly connected to the rear side of the machine body, and a crossbar is fixedly connected between two fixing plates. A movable seat is slidably sleeved on the outer side of the crossbar, and two movable seats are respectively fixedly connected to the corresponding racks.

At the same time, a traction motor drives the rotation of a traction roller, which, through the transmission of two gears, drives the rotation of two traction rollers, thereby pulling out the polyester needle-punched nonwoven fabric. Simultaneously, the two gears drive the rotation of two drive columns, which in turn drive the two frames and racks to reciprocate left and right. The two racks drive the forward and reverse rotation of four gears, which in turn drive the four hollow tubes and multiple blowers to swing left and right. This reciprocating swinging cold air cooling makes the cooling more uniform and comprehensive, greatly improving the cooling and shaping effect.
[0016] This utility model has a reasonable structural design. The setting of three pressure rollers that move back and forth and heating plate makes the heat pressing more uniform and comprehensive, making the non-woven fabric less prone to deformation. At the same time, the back and forth swinging blower head can blow cold air in a reciprocating manner to cool the fabric, making the cooling more uniform and comprehensive. This greatly improves the cooling and shaping effect and avoids secondary deformation caused by untimely cooling of the non-woven fabric and the transmission action. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Reference Figures 1-5 A heat-pressing and shaping device for polyester needle-punched nonwoven fabric includes a machine body 1, with openings 2 on both sides of the machine body 1. A traction motor 4 is fixedly connected to the front side of the machine body 1. Two traction rollers 5 are rotatably connected to the inner walls of the front and rear sides of the machine body 1. The output shaft of the traction motor 4 is fixedly connected to the front end of the corresponding traction roller 5. Two partitions 8 are fixedly connected inside the machine body 1. A heat-pressing mechanism 7 for heat-pressing polyester needle-punched nonwoven fabric is provided inside the machine body 1 on the left side of the partition 8. Gears 603 are fixedly connected to the rear ends of the two traction rollers 5. The two gears 603 mesh with each other. A double-sided cooling and shaping mechanism 6 is provided between the machine body 1 and the two gears 603. Two guide rollers 3 are rotatably connected to the inner walls of the front and rear sides of the machine body 1.
[0025] Furthermore, refer to Figures 1-3The hot pressing mechanism 7 includes two support plates 703 fixedly connected to the inner wall of the top of the machine body 1 and a mounting block 712 slidably disposed in the machine body 1, as well as heating plates 701 fixedly connected to the inner walls of the front and rear sides of the machine body 1. A worm gear 710 is rotatably connected to the front side of the mounting block 712. A drive motor 708 is fixedly connected to one side of the mounting block 712. A worm 707 is fixedly connected to the output shaft of the drive motor 708. The worm 707 meshes with the worm gear 710. A push-pull rod 711 is rotatably connected to the front side of the worm gear 710. One end of the push-pull rod 711 is rotatably connected to one side of the corresponding support plate 703. A connecting plate 714 is fixedly connected to the bottom of the mounting block 712. An electric push rod 705 is fixedly connected to the bottom of the connecting plate 714. A mounting frame 706 is fixedly connected to the output shaft of the electric push rod 705. Three pressure rollers 702 are rotatably connected to the inner walls of the front and rear sides of the mounting frame 706.
[0026] The above solution involves adjusting the distance between the pressure roller 702 and the heating plate 701 via an electric push rod 705 to perform hot pressing on polyester needle-punched nonwoven fabrics of different thicknesses. The drive motor 708 drives the rotation of the worm gear 707, which in turn drives the rotation of the worm wheel 710. The worm wheel 710 then drives the push-pull rod 711. Under the reaction force, the push-pull rod 711 will cause the mounting block 712, the connecting plate 714, and the three pressure rollers 702 to roll back and forth on the polyester needle-punched nonwoven fabric, making the hot pressing more uniform and comprehensive, and preventing the nonwoven fabric from deforming.
[0027] Furthermore, two telescopic rods 704 are fixedly connected between the connecting plate 714 and the mounting bracket 706, and an electric push rod 705 is located between the two telescopic rods 704 to facilitate guiding the mounting bracket 706 and make its lifting and lowering more stable.
[0028] Furthermore, the two support plates 703 are fixedly connected to the same guide plate 709. A sliding sleeve 713 is slidably sleeved on the outer side of the guide plate 709. The sliding sleeve 713 is fixedly connected to the top of the mounting block 712, which facilitates the guidance of the mounting block 712 and makes its movement more stable.
[0029] Furthermore, refer to Figure 1 , Figure 2 , Figure 4 and Figure 5The double-sided cooling and shaping mechanism 6 includes a sealing cover 602 fixedly connected to the front side of the body 1, and four hollow tubes 612 rotatably connected to the inner walls of the front and rear sides of the body 1. Each of the four hollow tubes 612 has a number of blowers 611 fixedly connected to one side of each other. The sealing cover 602 is connected to the front end of the four hollow tubes 612. A cooler 601 is fixedly connected to one side of the sealing cover 602. Each of the four hollow tubes 612 has a gear 609 fixedly connected to the rear end. A drive column 605 is fixedly connected to the rear side of the gear 603. A frame 604 is slidably sleeved on the outer side of the drive column 605. A rack 606 is fixedly connected to the side of each frame 604 that is far apart from each other. Each rack 606 meshes with the corresponding gear 609.
[0030] Using the above scheme: After hot pressing, the material is conveyed to the right side of the partition 8 and located between the four hollow tubes 612. Cold air is blown into the sealing cover 602 by the cold air blower 601, then enters the four hollow tubes 612. Finally, cold air is blown from multiple blower heads 611 to simultaneously cool and position the polyester needle-punched nonwoven fabric on both sides. Simultaneously, the traction motor 4 drives the rotation of a traction roller 5, which, through the transmission of two gears 603, drives the rotation of two traction rollers 5, thereby facilitating the cooling and positioning of the polyester needle-punched nonwoven fabric. The fabric is drawn out, and at the same time, two gears 603 drive the rotation of two drive columns 605. The two drive columns 605 drive the two frames 604 and rack 606 to reciprocate left and right. The two racks 606 drive the forward and reverse rotation of four gears 609. The four gears 609 drive the four hollow tubes 612 and multiple blowers 611 to swing left and right, thereby blowing cold air in a reciprocating swinging manner, making the cooling more uniform and comprehensive, and greatly improving the cooling and shaping effect.
[0031] Furthermore, four fixed plates 610 are fixedly connected to the rear side of the body 1. A crossbar 608 is fixedly connected between two fixed plates 610. A movable seat 607 is slidably sleeved on the outer side of the crossbar 608. Two movable seats 607 are fixedly connected to the corresponding racks 606 respectively, which facilitates the guidance of the racks 606 and makes their movement more stable.
[0032] Furthermore, a gap is formed between the two partitions 8 for the polyester needle-punched nonwoven fabric to pass through, which facilitates the passage of the polyester needle-punched nonwoven fabric.
[0033] In this invention, during use, polyester needle-punched nonwoven fabric enters the machine body 1 through the opening 2 on the left side. Guide rollers 3 guide the fabric, which is then conveyed between the heating plate 701 and the pressure rollers 702 for heat pressing. An electric push rod 705 adjusts the distance between the pressure rollers 702 and the heating plate 701 to allow for heat pressing of polyester needle-punched nonwoven fabrics of different thicknesses. A drive motor 708 drives the rotation of the worm gear 707, which in turn drives the rotation of the worm wheel 710. The worm wheel 710 then drives the push-pull rod 711. Under the reaction force, the push-pull rod 711 causes the mounting block 712, connecting plate 714, and three pressure rollers 702 to roll back and forth on the polyester needle-punched nonwoven fabric, resulting in more uniform and comprehensive heat pressing and preventing deformation of the nonwoven fabric. After heat pressing, the fabric is conveyed to the right side of the partition 8 and positioned between the four hollow tubes 612. During operation, cold air is blown into the sealed cover 602 by the air cooler 601, and then into the four hollow tubes 612. Finally, cold air is blown from multiple blower heads 611 to simultaneously cool and position the polyester needle-punched nonwoven fabric on both sides. At the same time, the traction motor 4 drives the rotation of a traction roller 5, which is driven by two gears 603 to pull out the polyester needle-punched nonwoven fabric. Meanwhile, the two gears 603 drive the rotation of two drive columns 605, which in turn drive the two frames 604 and racks 606 to reciprocate left and right. The two racks 606 drive the forward and reverse rotation of four gears 609, which in turn drive the four hollow tubes 612 and multiple blower heads 611 to swing left and right. This reciprocating swinging cold air cooling makes the cooling more uniform and comprehensive, greatly improving the cooling and shaping effect.
