Description

Technical Field

[0001] This invention relates to a hot pressing device for manufacturing nonwoven fabrics, belonging to the field of nonwoven fabric processing technology. Background Technology

[0002] Nonwoven fabric, also known as non-woven cloth, is composed of oriented or randomly arranged fibers. It is called cloth because it has the appearance and some properties of cloth. However, it is a fabric that is not formed by spinning and weaving. Instead, it is made by oriented or randomly arranging short textile fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding, or chemical methods.

[0003] A typical mask consists of two layers of non-woven fabric with a filter paper sandwiched in between. The stacked non-woven fabric needs to be hot-pressed, but traditional hot-pressing devices tend to stick the molten non-woven fabric to the conveying components, resulting in separation and the non-woven fabric being easily torn or ripped.

[0004] How to develop a hot pressing device and method for manufacturing nonwoven fabrics is an urgent problem to be solved. Summary of the Invention

[0005] The main objective of this invention is to address the shortcomings of existing technologies by providing a hot pressing apparatus and method for manufacturing nonwoven fabrics.

[0006] The objective of this invention can be achieved by adopting the following technical solution:

An inner connecting pipe connected to the hanger is disposed at the top of the segmented sleeve. An upper pulley is disposed on the outer wall of the upper shaft.

[0008] Furthermore, the pressing assembly includes a bracket disposed on the top of the base plate and a lower shaft disposed on the inner wall of the bracket, and a partition cylinder is disposed on one side of the bracket.

[0009] Furthermore, a conveying motor is provided on one side of one of the partition cylinders, the output shaft of the conveying motor is connected to the lower shaft, and a lower cylinder is provided on the middle outer wall of the lower shaft.

[0010] Furthermore, lower pulleys are provided at both ends of the lower shaft, and connecting belts are provided on the outer walls of the upper pulley and the lower pulley.

[0011] Furthermore, two swing arms are provided on one side of the partition cylinder, and a support rod is provided at one end of each swing arm. A rotating sleeve is provided on the outer wall of the support rod, and the rotating sleeve is connected to the connecting belt.

[0012] Furthermore, a cross groove is provided in the middle of the support rod, an adjusting cylinder is provided at the top of the bracket, a buckle is provided at the output end of the adjusting cylinder, and sliding buckles adapted to the cross groove are provided on both sides of the buckle.

[0013] Furthermore, the auxiliary components include a press machine disposed on the top of the base plate and an integrated cabinet disposed on one side of the press machine. A discharge pipe is disposed on one side of the press machine, and a lifting cylinder is disposed on the top. A crossbeam is disposed at the output end of the lifting cylinder, and the crossbeam is connected to the hanger.

[0014] Furthermore, a pressing cabinet is provided on the top of the base plate, a conveyor frame is provided on the bottom inner wall of the pressing cabinet, a conveyor belt is provided on the top of the conveyor frame, a rolling cylinder is provided on the top of the pressing cabinet, a pressure plate is provided on the output shaft of the rolling cylinder, and heating boxes are provided on both sides of the pressure plate.

[0015] A hot pressing method for a hot pressing device for manufacturing nonwoven fabrics includes the following steps:

[0016] Step 1: The straight rod connects to the ring heat pipe to heat the pressure ring evenly, and when the upper cylinder rotates, the protrusion of the pressure ring is used to heat press the stacked non-woven fabric.

[0017] Step 2: When the lower shaft rotates, it drives the lower pulley to rotate, which in turn drives the connecting belt to move. At the same time, the adjusting cylinder is activated, which drives the buckle plate to move, thus adjusting the opening angle of the swing arm.

[0018] Step 3: The two rotating sleeves drive the connecting belt to wrap around the upper pulley, which can provide torque for the rotation of the upper shaft.

[0019] Furthermore, an integrated cabinet is provided on the top of the base plate, and multiple feed pipes are provided on one side of the integrated cabinet. A folding compartment is provided on the top of the base plate, and the rolling mechanism is located between the folding compartment and the pressing machine.

[0020] The beneficial technical effects of the present invention are as follows: According to the hot pressing device and method for manufacturing nonwoven fabric, by setting a rolling pressing mechanism, which consists of an upper pressing component and a lower pressing component, the nonwoven fabric of a mask that has been pressed and stacked can be hot-pressed and formed. Furthermore, by relying on rolling pressing, the hot-melt nonwoven fabric area can be prevented from sticking to the device components. Simultaneously, the roller component facilitates the separation of the formed nonwoven fabric from the device. The upper pressing component is provided with multiple pads and pressure rings. For the pressing direction where the nonwoven fabric needs to be filled with a nose strip, the pressing shape can be micro-shaped by adjusting the position of the pads and pressure rings relative to the upper cylinder. The upper pressure component can be raised and lowered. When hot pressing is not required and only the nonwoven fabric needs to be conveyed, the upper pressure component can be immediately removed from the pressing area to prevent deformation of the nonwoven fabric. The internal wiring of the inner pipe at the bottom of the hanger is connected to the outside and provides protection for the wiring. A ring sleeve ensures that the wiring of the inner pipe remains electrically connected to the heating cylinder when it rotates, generating heat to the heat-conducting plates. Adjacent heat-conducting plates at the straight rod position are connected by the scattered heat-conducting plates stacked inside the bushing. The straight rod can slide inside the groove, and the groove gaps are sealed by washers to prevent heat loss. A connecting ring heat pipe evenly heats the pressure ring, and as the upper cylinder rotates, the pressure ring protrusions heat-press the stacked non-woven fabric. The heating cylinder contains heating wires. A lower pressing assembly is installed, where a conveyor motor starts, rotating the lower shaft to drive the lower cylinder, which also acts as a counterweight between the upper cylinder, pad ring, and pressure ring, ensuring the heat-pressed non-woven fabric is flat. The lower shaft rotation drives the lower pulley, which in turn moves the connecting belt. The adjusting cylinder activates, moving the buckle plate to adjust the opening angle of the swing arm. Two rotating sleeves drive the connecting belt to wrap around the upper pulley, providing torque for the upper shaft rotation and ensuring the upper... The upper and lower cylinders can rotate relative to each other and synchronously convey non-woven fabric. By setting auxiliary components, including an integrated cabinet, a presser, a folding chamber, and a pressing cabinet, multi-layered non-woven fabric can be hot-pressed from multiple directions. The integrated cabinet is equipped with three feed pipes, which can simultaneously accommodate three layers of non-woven fabric for conveying. After conveying, the fabric is stacked and output. The presser then performs edge rolling and nose strip placement. After passing through the rolling mechanism, both sides of the non-woven fabric of the mask are hot-pressed. After passing through the folding chamber, the non-woven fabric is folded and folded. At the same time, the rolling cylinder in the pressing cabinet drives the pressure plate to hot-press both ends of the non-woven fabric in the mask area. Attached Figure Description

Detailed Implementation

[0032] To enable those skilled in the art to understand the technical solution of the present invention more clearly, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0033] like Figures 1-10As shown, this embodiment provides a hot pressing device for manufacturing nonwoven fabric, including a base plate 1 and a rolling mechanism disposed on its top.

The upper pressing component includes a hanger 4 and an upper shaft 14 rotatably connected to its inner wall. A bushing 16 is fixedly connected to one end of the upper shaft 14. An upper cylinder 11 is fixedly connected to the outer wall of the bushing 16. Multiple gaskets 15 and pressure rings 17 are disposed on the outer wall of the upper cylinder 11. Multiple protrusions are disposed on the outer wall of the pressure ring 17. An annular heat pipe 18 is disposed on the inner wall of the pressure ring 17. The inner wall of the upper cylinder 11 is provided with a straight rod, and the outer wall of the upper cylinder 11 is provided with a sliding groove for the straight rod. One end of the straight rod is fixedly connected to a heat-conducting plate 19, which is located on the inner wall of the bushing 16. An electric heating cylinder 12 is provided between the two bushings 16. A link sleeve 13 is rotatably connected to the outer wall of the electric heating cylinder 12. The top of the link sleeve 13 is provided with an inner tube 9 fixedly connected to the hanger 4. An upper pulley 10 is fixedly connected to the outer wall of the upper shaft 14. By setting a rolling mechanism, which consists of an upper pressing component and a lower pressing component, the non-woven fabric of the mask that has been pressed and stacked can be hot-pressed and formed. And by rolling pressing, heat can be avoided. The molten nonwoven fabric adheres to the device components, while the roller components facilitate easy separation of the shaped nonwoven fabric from the device. The upper pressing assembly is equipped with multiple gaskets 15 and pressure rings 17. For pressing directions where the nonwoven fabric needs to be filled with nose strips, the pressing shape can be finely adjusted by adjusting the positions of the gaskets 15 and pressure rings relative to the upper cylinder 11. The upper pressing assembly can also be raised and lowered; when hot pressing is not required and only nonwoven fabric needs to be conveyed, the upper pressing assembly can be immediately removed from the pressing area to prevent deformation of the nonwoven fabric. The internal wiring of the inner pipe 9 at the bottom of the hanger 4 is connected to the outside and provides protection for the wiring. Meanwhile, the ring sleeve 13 ensures that the inner tube 9 wire remains electrically connected to the heating cylinder 12 when the heating cylinder 12 rotates, and heat is generated to the heat-conducting plate 19. The adjacent heat-conducting plates 19 at the straight rod position are connected by the scattered heat-conducting plates 19 stacked inside the bushing 16. At the same time, the straight rod can slide inside the groove, and the groove gap is sealed by the gasket ring 15 to prevent heat loss. Meanwhile, the straight rod is connected to the ring heat pipe 18 to uniformly heat the pressure ring 17. When the upper cylinder 11 rotates, the protrusion of the pressure ring 17 is used to heat press the stacked non-woven fabric. The heating cylinder 12 is equipped with heating wires inside.

The output end of the regulating cylinder 27 is fixedly connected to a buckle plate 26. The buckle plate 26 has sliding buckles on both sides that are adapted to the cross groove. By setting up a pressing component, the conveying motor 20 is started, and the lower shaft 29 rotates to drive the lower cylinder 21 to rotate. At the same time, it acts as the top-mounting component of the upper cylinder 11, the pad ring 15 and the pressure ring 17 to ensure the flatness of the heat-pressed nonwoven fabric. When the lower shaft 29 rotates, it drives the lower pulley 28 to rotate, and then drives the connecting belt 30 to move. When the regulating cylinder 27 is started, it drives the buckle plate 26 to move, which can adjust the opening angle of the swing arm 23. The two rotating sleeves 25 drive the connecting belt 30 to wrap around the upper pulley 10, which can provide torque for the rotation of the upper shaft 14 and ensure that the upper cylinder 11 and the lower cylinder 21 have relative rotation and synchronously convey the nonwoven fabric.

The bottom plate 1 is equipped with a folding chamber 3 on top, and the rolling mechanism is located between the folding chamber 3 and the press 7. By setting auxiliary components, including an integrated cabinet 6, a press 7, a folding chamber 3 and a pressing cabinet 2, multi-layer non-woven fabrics can be hot-pressed in multiple directions. The integrated cabinet 6 is equipped with three feed pipes 36, which can simultaneously accommodate three layers of non-woven fabric for conveying. After conveying, the fabric is stacked and output, and the press 7 performs edge rolling and nose strip placement. After passing through the rolling mechanism, the two sides of the non-woven fabric of the mask are hot-pressed. After the folding chamber 3, the non-woven fabric is folded and folded. At the same time, the rolling cylinder 35 in the pressing cabinet 2 drives the pressing plate 34 to hot-press the two ends of the non-woven fabric mask area.

[0037] In this embodiment, as Figures 1-10 As shown in the figure, the working process of the hot pressing device and hot pressing method for manufacturing nonwoven fabric provided in this embodiment is as follows:

[0038] Step 1: The straight rod connects to the ring heat pipe 18 to heat the pressure ring 17 evenly, and when the upper cylinder 11 rotates, the protrusion of the pressure ring 17 is used to heat press the stacked non-woven fabric.

[0039] Step 2: When the lower shaft 29 rotates, it drives the lower pulley 28 to rotate, which in turn drives the connecting belt 30 to move. Meanwhile, the adjusting cylinder 27 is activated, which drives the buckle plate 26 to move, thereby adjusting the opening angle of the swing arm 23.

[0040] Step 3: The two rotating sleeves 25 drive the connecting belt 30 to wrap around the upper pulley 10, which can provide torque for the rotation of the upper shaft 14.

[0041] In summary, in this embodiment, the hot pressing device and method for manufacturing nonwoven fabric, by setting a rolling pressing mechanism, which consists of an upper pressing component and a lower pressing component, can hot press and shape the nonwoven fabric of the mask that has been pressed and stacked. The rolling pressing prevents the hot-melted nonwoven fabric area from sticking to the device components. Simultaneously, the roller component facilitates the separation of the shaped nonwoven fabric from the device. The upper pressing component is equipped with multiple pads 15 and pressure rings 17. For the pressing direction where the nonwoven fabric needs to be filled with a nose strip, the pressing shape can be finely adjusted by adjusting the position of the pads 15 and pressure rings 17 relative to the upper cylinder 11. The upper pressing component can also be raised and lowered. When hot pressing is not required and only the nonwoven fabric needs to be conveyed, the upper pressing component can be raised and lowered. Immediately remove from the pressing area to avoid deformation of the non-woven fabric; the wires inside the inner pipe 9 at the bottom of the hanger 4 are connected to the outside and are protected by the inner pipe 9. The inner pipe 9 wires are kept electrically connected to the heating cylinder 12 when the heating cylinder 12 rotates, and heat is generated to the heat-conducting plate 19. The adjacent heat-conducting plates 19 at the straight rod position are connected by the stacking of the scattered heat-conducting plates 19 inside the bushing 16. The straight rod can slide inside the groove and the groove gap is sealed by the gasket 15 to prevent heat loss. The straight rod is connected to the ring heat pipe 18 to heat the pressure ring 17 evenly. When the upper cylinder 11 rotates, the pressure ring 17 protrusion is used to heat press the stacked non-woven fabric. The heating cylinder 12 is equipped with heating wires.

[0042] By setting up a pressing component, the conveyor motor 20 is started, and the lower shaft 29 rotates to drive the lower cylinder 21 to rotate. At the same time, it serves as the top-mounting component of the upper cylinder 11, the pad ring 15, and the pressure ring 17 to ensure the flatness of the heat-pressed nonwoven fabric. When the lower shaft 29 rotates, it drives the lower pulley 28 to rotate, and then drives the connecting belt 30 to move. The adjusting cylinder 27 is started, which drives the buckle plate 26 to move, thereby adjusting the opening angle of the swing arm 23. The two rotating sleeves 25 drive the connecting belt 30 to wrap around the upper pulley 10, which can provide torque for the rotation of the upper shaft 14 and ensure that the upper cylinder 11 and the lower cylinder 21 have relative rotation and synchronously convey the nonwoven fabric.

[0043] By setting up auxiliary components, including an integrated cabinet 6, a press machine 7, a folding chamber 3, and a pressing cabinet 2, multi-layered non-woven fabrics can be hot-pressed from multiple directions. The integrated cabinet 6 is equipped with three feed pipes 36, which can simultaneously accommodate three layers of non-woven fabric for conveying. After conveying, the fabric is stacked and output, and the press machine 7 performs edge rolling and nose strip placement. After passing through the rolling mechanism, both sides of the non-woven fabric of the mask are hot-pressed. After the folding chamber 3, the non-woven fabric is folded and folded. At the same time, the rolling cylinder 35 in the pressing cabinet 2 drives the pressing plate 34 to hot-press both ends of the non-woven fabric mask area.
