Description

Technical Field

[0001] This utility model relates to the field of automotive interior processing technology, specifically to a needle-punching forming machine for automotive interior fabric. Background Technology

[0002] Automotive interior processing is a crucial step in automobile manufacturing, impacting not only comfort and aesthetics but also the driving experience for consumers. As a key component of automotive interior decoration, automotive interior fabrics not only enhance the vehicle's appearance but also, to some extent, protect internal components, contributing to extended vehicle lifespan and maintaining optimal performance. Needle-punching machines are essential equipment for processing automotive interior fabrics, providing them with the necessary strength and stability to meet the requirements of different parts of the automotive interior. During needle-punching, the fabric is prone to breakage due to the piercing and friction from the needles, generating fine fiber debris. This debris adheres to the needle surface, intensifying friction between the needle and fibers and accelerating needle wear.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application number CN202210301697.0, application date 2022-03-24) provides a height-adjustable textile machine tool, including an outer machine frame and a needle punching mechanism. An inner machine frame is fitted inside the outer machine frame, and a horizontally arranged annular plate is fixedly connected to the inner sidewall of the upper port of the outer machine frame. The annular plate is slidably connected to the inner machine frame. The needle punching mechanism is used to repeatedly puncture the nonwoven fiber web, hooking and reinforcing the fibers into fabric. The needle punching mechanism includes needle punching parts fixedly installed at the upper end of the inner machine frame, and a horizontally arranged needle punching plate is provided inside the inner machine frame. The needle punching plate is slidably connected to the inner sidewall of the inner machine frame through multiple connecting rods on the peripheral sidewall. It also includes an adjustment mechanism for adjusting the height of the inner machine frame and a dust removal mechanism for removing lint and dust generated during the needle punching process. By setting a conversion mechanism, not only can the power source be switched, but the structure of the entire device is also made simpler and easier to operate during maintenance.

[0004] When needle-punching automotive interior fabric, fixing the fabric ensures precise positioning during the needle-punching process. The needles pierce along a preset trajectory and spacing, resulting in a precise pattern on the final interior fabric. However, the aforementioned device cannot guarantee that the interior fabric remains fixed during the needle-punching process, leading to inaccurate needle positioning and blurry patterns, which greatly affects the aesthetics and design integrity of the interior fabric. Utility Model Content

[0005] The purpose of this invention is to provide a needle-punching forming machine for automotive interior fabrics, in order to solve the problem mentioned in the background art that it is impossible to ensure that the interior fabric remains in a fixed state during the needle-punching process, resulting in inaccurate needle-punching positioning, blurry patterns on the product, and greatly affecting the aesthetics and design integrity of the interior fabric.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a needle-punching forming machine for automotive interior fabric, comprising a frame, a control console fixedly connected to the left side of the frame, a protective net connected to the upper front side of the frame, and a support frame fixedly connected to the upper surface of the frame near the protective net, while a needle-punching assembly is fixedly connected to the surface of the support frame; a limit rod is fixedly connected to the inner wall of the support frame, and an extrusion plate is slidably connected through the limit rod, and the extrusion plates are symmetrically distributed about the center of the frame; a negative pressure box is fixedly connected to the upper surface of the needle-punching assembly, and one end of an air blowing pipe is fixedly connected to the lower rear side of the negative pressure box, and a nozzle is fixedly connected to the other end of the air blowing pipe; a one-way valve is fixedly connected to the surface of the air blowing pipe.

[0009] Preferably, a fixing block is fixedly connected to the upper surface of the support frame, and a transmission shaft is rotatably arranged inside the fixing block, and bevel gears are fixedly connected to both the surface of the transmission shaft and the surface of the rotating shaft.

[0010] Preferably, a baffle is fixedly connected to the upper surface of the needle-punching assembly, and a sliding shaft is rotatably provided inside the baffle, and a connecting plate is movably connected to the surface of the sliding shaft.

[0011] Preferably, a connecting block is fixedly connected to the end of the drive shaft, and one end of a connecting rod is sleeved on the surface of the connecting block, and the other end of the connecting rod is sleeved on one end of the connecting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the automotive interior fabric needle punching forming machine adopts a novel structural design, the specific details of which are as follows:

[0014] (1) The needle punching machine for automotive interior fabric ensures that the interior fabric will not deviate during needle punching by setting the extrusion plate and the limiting rod, so that the needle can puncture according to the preset pattern and trajectory, while ensuring that the interior pattern is presented clearly and completely, greatly improving the aesthetics of the interior fabric.

[0015] Furthermore, it prevents the interior fabric from wrinkling due to movement during needle punching, ensuring a smooth and flat finished product surface, while also improving the working efficiency of the device.

[0016] (2) The needle punching machine for automotive interior fabric effectively reduces the residue of fiber debris on the surface of the needle punch by setting a negative pressure box and nozzle, avoiding the impact of fiber debris on the puncture performance of the needle punch, thereby ensuring uniform needle punching density and depth of the interior fabric.

[0017] Furthermore, reducing friction between the needle and fiber debris extends the service life of the needle and improves the overall quality stability and physical properties of the interior fabric.

[0018] (3) The needle punching forming machine for automotive interior fabric improves the stability of the device during operation by setting up a protective net and a support frame, avoiding shaking caused by vibration during operation. At the same time, the protective net can effectively block foreign objects from entering the equipment, ensuring stable operation of the device. Attached Figure Description

[0027] 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 protection scope of the present utility model.

[0028] Example 1: By using the limiting rod 8, protective net 5, and support frame 3, the needle is ensured to always pierce the interior fabric vertically and accurately, enabling the device to operate stably. Figures 1-3 As shown: It includes a frame 1, a control console 2 is fixedly connected to the left side of the frame 1, a protective net 5 is connected to the upper front side of the frame 1, and a support frame 3 is fixedly connected to the upper surface of the frame 1 near the protective net 5. At the same time, a needle-punching assembly 4 is fixedly connected to the surface of the support frame 3. A limit rod 8 is fixedly connected to the inner wall of the support frame 3, and a compression plate 9 is slidably connected through the limit rod 8. The compression plates 9 are symmetrically distributed about the center of the frame 1. A negative pressure box 20 is fixedly connected to the upper surface of the needle-punching assembly 4, and one end of an air blowing pipe 19 is fixedly connected to the lower rear side of the negative pressure box 20. A nozzle 18 is fixedly connected to the other end of the air blowing pipe 19, and a one-way valve 21 is fixedly connected to the surface of the air blowing pipe 19.

[0029] The workers transport the interior fabric to be processed to the upper surface of the frame 1 via a conveying device. The control console 2 then guides the fabric from the upper surface of the frame 1 to the needle-punching area on the frame 1 surface. During the transport of the fabric, the workers ensure that it moves forward at a uniform speed and smoothly. Once the fabric enters the needle-punching area, the needle-punching assembly 4 begins to work, reciprocating up and down on the upper surface of the fabric to shape it. The protective net 5 and support frame 3 enhance the stability of the device during operation, preventing shaking caused by vibration. The protective net 5 also effectively blocks foreign objects from entering the equipment, ensuring stable operation.

[0030] In Example 2, unlike Example 1, the inclusion of a motor 6, a pressing plate 9, and a support frame 3 prevents the inner lining fabric from shifting during operation, thus improving the device's efficiency. Figures 4-5 As shown: A motor 6 is fixedly connected to the upper surface of the support frame 3, and a rotating shaft 7 is fixedly connected to the output end of the motor 6. The rotating shaft 7 is rotatably installed inside the support frame 3. A pressing plate 9 is threadedly connected to the surface of the rotating shaft 7, and the pressing plate 9 is in contact with the upper surface of the frame 1. A fixing block 11 is fixedly connected to the upper surface of the support frame 3, and a transmission shaft 12 is rotatably installed inside the fixing block 11. A bevel gear 10 is fixedly connected to both the surface of the transmission shaft 12 and the surface of the rotating shaft 7.

[0031] When the interior fabric is conveyed to the upper surface of the frame 1 by the conveying device, the motor 6 starts to rotate, driving the output shaft 7 to rotate. At the same time, the surface of the shaft 7 is threaded with an extrusion plate 9, which moves inside the support frame 3 under the action of the limiting rod 8. This allows the extrusion plate 9 to fix the interior fabric on the upper surface of the frame 1, ensuring that the interior fabric will not deviate during needle punching. This allows the needle to pierce according to the preset pattern and trajectory, while ensuring that the interior pattern is presented clearly and completely, greatly improving the aesthetics of the interior fabric and preventing wrinkles caused by movement during needle punching. This ensures that the finished product surface is flat and smooth, while also improving the working efficiency of the device.

[0032] In Example 3, unlike Example 2, the baffle 15, nozzle 18, and connecting plate 17 reduce the residue of fiber debris on the surface of the needle-punching assembly 4, thus improving the working quality of the device. Figures 6-7 As shown: A baffle 15 is fixedly connected to the upper surface of the needle assembly 4, and a sliding shaft 16 is rotatably arranged inside the baffle 15. A connecting plate 17 is movably connected to the surface of the sliding shaft 16. A connecting block 13 is fixedly connected to the end of the transmission shaft 12. One end of a connecting rod 14 is sleeved on the surface of the connecting block 13, and the other end of the connecting rod 14 is sleeved on the end of the connecting plate 17. A nozzle 18 is fixedly connected to the other end of the connecting plate 17, and the nozzles 18 are symmetrically distributed about the center of the needle assembly 4.

[0033] By installing bevel gears 10 on both the surface of the rotating shaft 7 and the surface of the transmission shaft 12, the rotation of the rotating shaft 7 drives the transmission shaft 12 to rotate inside the fixed block 11. As the transmission shaft 12 rotates, it drives the connecting block 13 at the end to rotate. Through the connecting rod 14, the rotation of the transmission shaft 12 drives the connecting plate 17 to swing the nozzle 18 on the upper surface of the frame 1 around the sliding shaft 16. The air blowing pipe 19 is a flexible hose. The one-way valve 21 installed on the surface of the air blowing pipe 19 improves the stability of the device, effectively reduces the residue of fiber debris on the surface of the needle, avoids the impact of fiber debris on the piercing performance of the needle, and thus ensures the uniformity of the needle punching density and depth of the interior fabric.

[0034] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
