Description

Technical Field

[0001] This invention relates to the field of textile technology, specifically to a high-quality synthetic fiber blanket production line and its production process. Background Technology

[0002] Synthetic fiber blankets are widely used in home, hotel, medical, and industrial fields due to their warmth, durability, and cost advantages. Traditional synthetic fiber blanket production lines typically include processes such as opening, carding, web laying, needle punching, lamination and setting, and winding. In the lamination and setting process, two layers of materials are usually firmly bonded together by hot pressing. However, because the edges of the raw blanket are relatively thin and the middle is thicker, traditional pressing equipment can only press the thicker middle area of ​​the raw blanket, failing to effectively press the edges, ultimately affecting the quality of the finished raw blanket.

[0003] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned shortcomings by providing a high-quality synthetic fiber carpet production line that can press the raw carpet in sections, ensuring that different areas of the raw carpet can be firmly bonded, thereby effectively improving the quality of the carpet.

[0005] To achieve the above objectives, the solution of the present invention is: a high-quality synthetic fiber blanket production line, comprising a frame, wherein a conveying mechanism and a composite shaping mechanism are provided on the frame, the composite shaping mechanism is located above the conveying mechanism, the composite shaping mechanism includes a mounting frame, a pre-pressing assembly and a post-pressing assembly, both the pre-pressing assembly and the post-pressing assembly include a plurality of hot pressing groups arranged side by side on the mounting frame perpendicular to the conveying direction, the hot pressing groups of the pre-pressing group and the post-pressing group are arranged alternately, the hot pressing group includes a floating frame, the mounting frame is fixed on the frame, the floating frame is floatingly mounted on the mounting frame through a double swing arm mechanism to floatingly press the blank blanket according to the thickness requirements of different areas of the blank blanket, a plurality of pressing rollers are provided on the floating frame along the conveying direction, the pressing rollers are connected to a heating device to hot press the blank blanket.

[0006] Furthermore, in order to adapt to carpets with different pressing requirements, the pressing roller includes a roller body and several annular inserts with different radial widths. The roller body is provided with an annular groove along the axial direction for movably inserting the annular inserts. The annular inserts are movably disposed in the annular grooves so that the weight of the pressing roller can be changed by different annular inserts, thereby changing the pressing force of the pressing roller.

[0007] Furthermore, in order to movably install the annular insert within the annular groove of the roller body to change its pressing force by adjusting the mass of the pressing roller, the outer diameter of the annular insert is adapted to the outer diameter of the annular groove, and the inner diameter of the annular insert is less than or equal to the inner diameter of the annular groove.

[0008] Furthermore, in order to float the floating frame and thus ensure that the pressing force of the pressing roller is different in different areas of the blank; the double swing arm mechanism includes a first link and a second link, the upper ends of the first link and the second link are rotatably mounted on the mounting frame, the lower end of the first link is rotatably connected to the front side of the floating frame, and the lower end of the second link is rotatably connected to the rear side of the floating frame.

[0009] Furthermore, in order to cold press and shape the blank carpet, the upper and lower pressure plates are designed with irregular shapes to stretch the carpet to a certain extent. The composite shaping mechanism also includes a cold pressing assembly, which includes a lower pressure plate, an upper pressure plate, and a drive group. The upper pressure plate is located above the lower pressure plate. Both the upper and lower pressure plates have a wave-shaped structure. Cooling water circulation channels are provided inside both the upper and lower pressure plates. The drive group is connected to the upper pressure plate to drive the upper pressure plate to approach the lower pressure plate to cool and shape the blank carpet.

[0010] Furthermore, in order to drive the upper pressure plate to move downwards, the drive assembly is provided in two sets, which are symmetrically arranged on the left and right sides of the frame. The drive assembly includes a drive motor, a cam, and a drive plate. The drive motor is fixedly mounted on the frame, the cam is mounted on the motor shaft of the drive motor and is located above the drive plate, the left and right sides of the frame are symmetrically provided with guide columns, the left and right sides of the drive plate are movably inserted through the guide columns, and the guide columns are also fitted with elastic reset members located below the drive plate. The upper pressure plate is installed on the lower side of the drive plate.

[0011] Furthermore, in order to combine different fiber layers of the raw blanket together, the high-quality chemical fiber blanket production line also includes a needle punching mechanism located in front of the composite shaping mechanism. The needle punching mechanism includes an upper needle punching assembly, which includes an upper needle plate and a drive structure for driving the upper needle plate to move in an elliptical trajectory. The upper needle plate is evenly distributed with a number of upper needles.

[0012] Furthermore, in order to drive the upper needle plate to move along an elliptical trajectory, causing the fibers to entangle in the longitudinal and transverse directions, the drive structure includes a guide frame, a swing arm, and a rocker arm. The guide frame is vertically fixed on the machine frame and has guide grooves extending vertically. A guide block is slidably installed in the guide grooves. The upper end of the rocker arm is rotatably installed on the guide block, and the lower end of the rocker arm is rotatably connected to the upper needle plate. The upper end of the swing arm is rotatably installed on the lower end of the guide frame, and the lower end of the swing arm is rotatably installed in the middle of the rocker arm to constrain the rocker arm's swing and thus drive the upper needle plate to move along an elliptical trajectory.

[0013] Furthermore, in order to form a movable lower needle plate structure to improve the fiber entanglement effect, the needle punching mechanism also includes a lower needle punching assembly, which includes a lower needle plate located below the upper needle plate. The lower needle plate is evenly distributed with a plurality of lower needles, and the upper and lower needles are staggered. The lower needle plate is elastically mounted on the frame by an elastic element.

[0014] Another objective of this invention is to address the above-mentioned shortcomings by providing a production process for a high-quality synthetic fiber carpet production line that can produce high-quality carpets.

[0015] Another solution adopted by the present invention to solve the above-mentioned technical problem is: a production process for a high-quality synthetic fiber blanket production line, comprising the following steps:

[0016] S1: The blank blanket is conveyed to the needle punching mechanism. The upper needle plate moves in an elliptical trajectory under the drive structure, causing the fibers to entangle in the longitudinal and transverse directions. At the same time, the lower needle plate moves slightly under the action of the elastic element, further improving the fiber entanglement effect.

[0017] S2: The needle-punched blank is conveyed to the front pre-compression assembly and the rear pre-compression assembly, which perform zoned hot pressing and shaping on the blank.

[0018] S3: The hot-pressed blank continues to be conveyed to the cold-press assembly, where the blank is stretched and shaped by the corrugated upper and lower pressure plates.

[0019] Compared with the prior art, the present invention has the following advantages: The present invention performs hot pressing and shaping of the blank carpet in sections, and the front pre-pressing component and the rear pre-pressing component are staggered to ensure that each area of ​​the blank carpet can be fully hot-pressed and shaped. In addition, since the hot pressing group relies on the weight of the pressing roller itself to achieve adaptive pressing, in order to ensure that the pressing degree of the middle area of ​​the blank carpet meets the requirements, the present invention also provides a cold pressing component, which can achieve a cooling effect while pressing the middle area of ​​the blank carpet to ensure the shaping effect of the blank carpet. At the same time, the cold pressing component adopts an irregular structure, which can stretch the blank carpet to a certain extent. Furthermore, the present invention provides a needle punching mechanism in front of the composite shaping mechanism. The upper needle punching component moves in an elliptical trajectory, which can ensure that the fibers are fully entangled together in the transverse and longitudinal directions. Combined with the micro-vibration mechanism of the lower needle plate, it effectively improves the entanglement effect between the fiber layers of the blank carpet, thereby ensuring the quality of the carpet.

[0026] To further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0027] Example 1: As Figure 1-4 As shown, this embodiment provides a high-quality synthetic fiber blanket production line, including a frame 1.

The frame 1 is equipped with a support plate located below the conveying section. The composite shaping mechanism includes a mounting frame, a front pre-compression assembly 3, and a rear pre-compression assembly 4. Both the front pre-compression assembly 3 and the rear pre-compression assembly 4 include components perpendicular to the conveying direction and... Several hot pressing groups are arranged on the mounting frame, with the hot pressing groups of the front pre-pressing group and the hot pressing group of the rear pre-pressing group arranged alternately. Each hot pressing group includes a mounting frame 5 and a floating frame 6. The mounting frame 5 is fixed on the machine frame 1, and the floating frame 6 is floatingly mounted on the mounting frame 5 through a double swing rod 18 mechanism to float and press the blank blanket according to the thickness requirements of different areas of the blank blanket. Several pressing rollers 7 are arranged on the floating frame 6 along the conveying direction. The pressing rollers 7 are connected to heating equipment to hot press the blank blanket. The pressing rollers 7 are pressed and cooperated with the support plate to press the blank blanket and form the blank blanket composite.

[0028] In this embodiment, to adapt to carpets with different pressing requirements, the pressing roller 7 includes a roller body and several annular inserts with different radial widths. The roller body has an annular groove along the axial direction for movably inserting the annular inserts. The annular inserts are movably disposed in the annular groove to change the weight of the pressing roller 7 and thus change the pressing force of the pressing roller 7 by changing different annular inserts. One side of the pressing roller 7 is an opening of the annular groove, and a limiting cover for limiting the installation of the annular inserts is provided on one side of the opening of the annular groove. The limiting cover is installed on the roller body by bolts. The diameter of the limiting cover is larger than the outer diameter of the annular groove.

The composite shaping mechanism also includes a cold pressing assembly, which includes a lower pressure plate 10, an upper pressure plate 11 and a drive group. The upper pressure plate 11 is located above the lower pressure plate 10. Both the upper pressure plate 11 and the lower pressure plate 10 have a wave-shaped structure. Cooling water circulation channels are provided in both the upper pressure plate 11 and the lower pressure plate 10. The drive group is connected to the upper pressure plate 11 to drive the upper pressure plate 11 to approach the lower pressure plate 10 to cool and shape the blank carpet.

[0032] In this embodiment, in order to drive the upper pressure plate 11 to move towards the lower pressure plate 10, the drive group is provided in two sets, which are symmetrically arranged on the left and right sides of the frame 1. The drive group includes a drive motor 12, a cam 13 and a drive plate. The drive motor 12 is fixedly mounted on the frame 1. The cam 13 is mounted on the motor shaft of the drive motor 12 and is located above the drive plate. The left and right sides of the frame 1 are symmetrically provided with guide posts 14. The left and right sides of the drive plate are movably inserted through the guide posts 14. The guide posts 14 are also fitted with elastic reset members located below the drive plate. The upper pressure plate 11 is installed on the lower side of the drive plate.

[0033] In this embodiment, in order to composite different fiber layers of the raw blanket together, the high-quality chemical fiber blanket production line also includes a needle punching mechanism located in front of the composite shaping mechanism. The needle punching mechanism includes an upper needle punching assembly, which includes an upper needle plate 15 and a driving structure for driving the upper needle plate 15 to move in an elliptical trajectory. The upper needle plate 15 is evenly distributed with a plurality of upper needles.

[0034] In this embodiment, in order to drive the upper needle plate 15 to move in an elliptical trajectory, the drive structure causes the fibers to entangle in the longitudinal and transverse directions; the drive structure includes a guide frame 17, a swing rod 18, and a rocker arm 19. The guide frame 17 is vertically fixed on the frame 1. The guide frame 17 is provided with guide grooves that extend vertically. A guide block is slidably installed in the guide groove. The upper end of the rocker arm 19 is rotatably installed on the guide block, and the lower end of the rocker arm 19 is rotatably connected to the upper needle plate 15. The upper end of the swing rod 18 is rotatably installed on the lower end of the guide frame 17, and the lower end of the swing rod 18 is rotatably installed in the middle of the rocker arm 19 to constrain the swing of the rocker arm 19 and thus drive the upper needle plate 15 to move in an elliptical trajectory.

[0035] In this embodiment, in order to form a movable structure for the lower needle plate 16 to improve the fiber entanglement effect, the needle punching mechanism further includes a lower needle punching assembly, which includes a lower needle plate 16 located below the upper needle plate 15. The lower needle plate 16 is evenly distributed with a plurality of lower needles, and the upper needles and lower needles are staggered. The lower needle plate 16 is elastically mounted on the frame 1 by an elastic member.

[0036] Example 2: A production process for a high-quality synthetic fiber blanket production line, comprising the following steps:

[0037] S1: The blank blanket is conveyed to the needle punching mechanism. The upper needle plate 15 moves in an elliptical trajectory under the drive structure, causing the fibers to entangle in the longitudinal and transverse directions. At the same time, the lower needle plate 16 moves slightly under the action of the elastic element, further improving the fiber entanglement effect.

[0038] S2: The needle-punched blank is conveyed to the front pre-compression assembly 3 and the rear pre-compression assembly 4, and the front pre-compression assembly 3 and the rear pre-compression assembly 4 perform zoned hot pressing and shaping of the blank.

[0039] S3: The hot-pressed blank continues to be conveyed to the cold-press assembly, where the blank is stretched and shaped by the corrugated upper pressure plate 11 and lower pressure plate 10.

[0040] This invention uses a zoned hot-pressing method to shape the raw carpet. The front and rear pre-pressing components are staggered to ensure that each area of ​​the raw carpet is fully hot-pressed. Furthermore, since the hot-pressing assembly relies on the weight of the pressing rollers for adaptive pressing, a cold-pressing component is also included to ensure the required pressing degree in the central area of ​​the raw carpet. This component presses the central area of ​​the raw carpet while simultaneously cooling it, ensuring the shaping effect. The cold-pressing component also employs a uniquely shaped structure, which can stretch the raw carpet to a certain extent. Additionally, a needle-punching mechanism is provided before the composite shaping mechanism. The upper needle-punching component moves along an elliptical trajectory, ensuring that the fibers are fully entangled in both the transverse and longitudinal directions. Combined with the micro-vibration mechanism of the lower needle plate 16, this effectively improves the entanglement effect between the fiber layers of the raw carpet, thereby ensuring the quality of the carpet.
