Description

Technical Field

[0001] This invention relates to the field of nonwoven fabric processing technology, specifically to adaptive thickness double-sided needle-punched nonwoven fabric processing equipment. Background Technology

[0002] Double-sided needle-punched nonwoven fabric is made by repeatedly puncturing and reinforcing the fiber web on both sides through a needle-punching process, causing the fibers to entangle and form a nonwoven material with a double-sided structure and high strength. Short fibers (such as polyester and polypropylene) are opened and carded to form a uniform fiber web. Through processes such as pre-punching, main punching, and patterned needle punching, the fiber web is repeatedly punctured to increase the fiber entanglement density and improve the strength and thickness of the fabric. The double-sided needle-punching process allows the fibers to form a strong entanglement on both sides, significantly improving tensile strength and abrasion resistance, making it suitable for applications that need to withstand external forces.

[0003] Workers need to adjust the needle-punching depth according to the fiber type and product thickness. Too deep a needle may damage the fiber structure, while too shallow a needle may result in insufficient entanglement. However, existing processing equipment usually requires workers to manually adjust the needle-punching depth. Manual adjustment may not be precise enough and is not convenient for mass production of nonwoven fabrics. Therefore, we propose an adaptive thickness double-sided needle-punched nonwoven fabric processing equipment. Summary of the Invention

[0004] The purpose of this invention is to provide an adaptive thickness double-sided needle-punched nonwoven fabric processing equipment to solve the problem mentioned in the background art that the existing processing equipment usually requires the operator to manually adjust the needle insertion depth, which may not be precise enough and is not convenient for mass production of nonwoven fabrics.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adaptive thickness double-sided needle-punched nonwoven fabric processing equipment, comprising: a worktable;

[0006] Also includes:

[0007] Bottom needle holder, the bottom needle holder is located below the worktable;

[0008] The top needle seat is set above the workbench. The bottom needle seat and the top needle seat cooperate with each other to pierce into the non-woven fabric from both sides, so that the fibers on both sides of the non-woven fabric are tightly bonded together to form a three-dimensional structure.

[0009] An adaptive tension assembly is located at the front end of the worktable. The adaptive tension assembly is used to make adaptive adjustments according to the thickness of the composite nonwoven fabric to maintain appropriate tension of the composite nonwoven fabric and avoid displacement or wrinkles caused by relaxation. The adaptive tension assembly includes two tension plates, with a pressure roller and a movable roller respectively arranged between the two tension plates. The movable roller is rotatably connected to the tension plate, and two pressure springs are arranged on both sides of the pressure roller.

[0010] The top needle holder and the bottom needle holder are slidably connected to the worktable. Multiple telescopic rods are fixedly connected to both ends of the top needle holder. Telescopic cylinders are slidably connected to the top of the telescopic rods. Telescopic springs are installed inside the telescopic cylinders. Sliding seats are fixedly connected between the multiple telescopic cylinders. Multiple cylinders are fixedly connected to the top of the sliding seats and the bottom of the bottom needle holder.

[0011] The inner walls of both tension plates are provided with sliding grooves, and sliding blocks are slidably connected inside the sliding grooves. The sliding blocks are rotatably connected to the pressure rollers, and pressure springs are set inside the sliding grooves.

[0012] The workbench has a movable groove at its bottom, and a movable plate is slidably connected inside the movable groove. Multiple pinholes are equidistantly opened on the inner wall of the movable plate, and a transmission component is provided between the movable plate and the sliding block.

[0013] The movable plate has limit plates fixedly connected to both its front and rear ends, and the limit plates are slidably connected to the worktable.

[0014] The transmission assembly includes a transmission rod, the middle end of which is rotatably connected to the worktable, and both ends of the transmission rod are slidably connected to movable tubes.

[0015] One of the movable tubes is movably connected to the sliding block, and the top of the other movable tube is movably connected to a support plate. The support plate is slidably connected to the worktable, and the top of the support plate is fixedly connected to the movable plate.

[0016] The present invention has at least the following beneficial effects:

[0017] Workers can thread the nonwoven fabric between the pressure roller and the movable roller. Under the weight of the pressure roller itself and the action of the pressure spring, the fabric is pressed adaptively according to its thickness. At the same time, the movable tube connected to it moves, while another movable tube moves in the opposite direction under the action of the transmission rod. This adjusts the position of the movable plate and changes the exposure range of the bottom needle seat. The thicker the nonwoven fabric, the lower the position of the movable plate, the larger the exposure range of the bottom needle seat needle, and the deeper the piercing between the bottom and top needle seats. The device is adjusted adaptively according to the thickness of the nonwoven fabric to prevent the device from piercing too deeply, which may damage the fiber structure, or too shallowly, which may result in insufficient entanglement.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1

[0026] Please see Figures 1 to 5 The present invention provides a technical solution: an adaptive thickness double-sided needle-punched nonwoven fabric processing equipment, comprising: a worktable 001;

[0027] Also includes:

[0028] Bottom needle holder 002 is located below the worktable 001;

[0029] Top needle seat 003 is positioned above workbench 001. Bottom needle seat 002 and top needle seat 003 cooperate with each other to pierce into the nonwoven fabric from both sides, so that the fibers on both sides of the nonwoven fabric are tightly bonded together to form a three-dimensional structure.

[0030] An adaptive tension component 004 is located at the front end of the worktable 001. The adaptive tension component 004 is used to adaptively adjust according to the thickness of the composite nonwoven fabric to maintain appropriate tension of the composite nonwoven fabric and avoid displacement or wrinkles caused by relaxation. The adaptive tension component 004 includes two tension plates 401. A pressure roller 402 and a movable roller 403 are respectively arranged between the two tension plates 401. The movable roller 403 is rotatably connected to the tension plate 401. Two pressure springs 404 are arranged on both sides of the pressure roller 402.

[0031] Both the top needle holder 003 and the bottom needle holder 002 are slidably connected to the worktable 001. Multiple telescopic rods 310 are fixedly connected to both ends of the top needle holder 003. A telescopic cylinder 320 is slidably connected to the top of the telescopic rod 310. A telescopic spring 330 is installed inside the telescopic cylinder 320. A sliding seat 340 is fixedly connected between the multiple telescopic cylinders 320. Multiple cylinders 350 are fixedly connected to the top of the sliding seat 340 and the bottom of the bottom needle holder 002.

[0032] The adaptive component can improve the tension of the nonwoven fabric. The operator can insert the nonwoven fabric between the pressure roller 402 and the movable roller 403. Under the weight of the pressure roller 402 and the action of the pressure spring 404, the nonwoven fabric is adaptively pressed according to its thickness, so that the composite nonwoven fabric has tension and can improve its adhesion. At the same time, the bottom needle seat 002 and the top needle seat 003 cooperate with each other, and their needles are interlaced. The top needle seat 003 and the bottom needle seat 002 press the composite nonwoven fabric from the top and bottom directions respectively through the cylinder 350, and the nonwoven fabric is pierced on both sides, which improves the adhesion of the nonwoven fabric and further entangles the composite nonwoven fabric.

[0033] The inner walls of both tension plates 401 are provided with sliding grooves 410, and sliding blocks 420 are slidably connected inside the sliding grooves 410. The sliding blocks 420 are rotatably connected to the pressure rollers 402, and the pressure springs 404 are disposed inside the sliding grooves 410.

[0034] The bottom of the workbench 001 is provided with a movable groove 110, and a movable plate 120 is slidably connected inside the movable groove 110. Multiple pinholes 130 are equidistantly provided on the inner wall of the movable plate 120, and a transmission assembly 005 is provided between the movable plate 120 and the sliding block 420.

[0035] The needle of the bottom needle seat 002 can penetrate the needle hole 130 and pierce the interior of the composite nonwoven fabric. The top needle seat 003 presses against the movable plate 120. After the needle touches the movable plate 120, under the pressure, the telescopic rod 310 of the top needle seat 003 moves into the telescopic cylinder 320 of the sliding seat 340, thereby providing a certain buffer space for the top needle seat 003, preventing excessive wear of the needle of the top needle seat 003, and facilitating the adjustment of the position of the movable plate 120.

[0036] Limiting plates 140 are fixedly connected to both the front and rear ends of the movable plate 120, and the limiting plates 140 are slidably connected to the worktable 001.

[0037] Example 2

[0038] like Figure 5In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the transmission assembly 005 includes a transmission rod 501. The middle end of the transmission rod 501 is rotatably connected to the worktable 001, and both ends of the transmission rod 501 are slidably connected to movable tubes 502.

[0039] One of the movable tubes 502 is movably connected to the sliding block 420, and the top of the other movable tube 502 is movably connected to the support plate 503. The support plate 503 is slidably connected to the worktable 001, and the top of the support plate 503 is fixedly connected to the movable plate 120.

[0040] The pressure roller 402 adjusts with the thickness of the composite nonwoven fabric. When the thickness of the composite nonwoven fabric changes, the movable tube 502 connected to the sliding block 420 is raised. Under the action of the transmission rod 501, the other movable tube 502 moves in the opposite direction. Since the support plate 503 is limited by the worktable 001, it can only move up and down in a straight line. Thus, the two movable tubes 502 can drive the movable plate 120 to move up and down inside the movable groove 110, thereby adjusting the position of the movable plate 120 and changing the protrusion range of the bottom needle seat 002. The thicker the nonwoven fabric, the lower the position of the movable plate 120, the larger the protrusion range of the bottom needle seat 002, and the deeper the piercing of the bottom needle seat 002 and the top needle seat 003. The device is designed to facilitate the linkage between the movable plate 120 and the pressure roller 402, and to adaptively adjust the piercing depth of the device according to the thickness of the nonwoven fabric, preventing the device from piercing too deeply, which may damage the fiber structure, or too shallowly, which may result in insufficient entanglement.
