Description

Technical Field

[0001] This invention belongs to the technical field of down jacket patching devices, specifically an automatic patching device for warm down jacket fabrics. Background Technology

[0002] In the production and processing of down, patching is often required on down jacket fabrics. Through patching devices, patches with specific functions (such as anti-counterfeiting labels, brand labels, reflective patches, and warmth-enhancing patches) are precisely and efficiently automatically applied to designated positions on the down jacket fabric. This ensures the transmission of product information, the realization of functions, and the quality of appearance, while improving production efficiency and patching accuracy.

[0003] Patent application number 202210058992.8 discloses a device for patching down jacket fabric. This device, through the synergistic action of a spherical protrusion and a mating ring, can lift and stably clamp the down jacket fabric at the positioning hole. The adjusting wheel on the mating ring can also smooth out wrinkles in the fabric, effectively solving the technical problem of uneven fabric during patching. However, this device can only perform single-sided patching of down jacket fabric, making it difficult to adapt to the current diversified production needs. In actual production, some functional down jackets (such as outdoor cold-weather styles) often require multiple labels for washing requirements, safety warnings, etc., necessitating patching on both the inner and outer sides of the fabric. Simplified and complete labels are affixed; for exported down jackets, compliance standards of certain countries or regions must be followed, requiring the marking of key information such as the EU CE mark on the visible (outer) side of the fabric, while retaining complete instruction documents on the inner side. These scenarios all present a clear requirement for double-sided labeling. In this case, using existing equipment requires completing the labeling on one side first, and then manually flipping the fabric to perform the labeling operation on the other side. This process is not only cumbersome, but also prone to fabric displacement and labeling position deviation due to manual intervention, reducing labeling accuracy and consistency, and significantly affecting production efficiency. To address this issue, we propose an automatic labeling device for thermal down jacket fabrics. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic patching device for thermal down jacket fabrics to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic patching device for down jacket fabric, comprising a base frame, a push hydraulic cylinder fixed on the base frame, a support, and an arc-shaped concave plate and a spherical protrusion disposed on the support, wherein the support is provided with a flipping mechanism, the flipping mechanism comprising: Rotate the flipper mounted on the bracket to flip the down jacket fabric. The flipping frame is provided with two sets of upper concave frames and two sets of lower concave frames. Each of the upper and lower concave frames is provided with two sets of limiting plates. A rubber plate is fixedly provided on the limiting plate for clamping the down jacket fabric. A lifting hydraulic rod is installed between the upper and lower concave frames to adjust the vertical distance between the two sets of limiting plates according to the different thicknesses of down jacket fabrics.

[0006] Preferably, a side motor is fixedly installed on one side of the bracket, and a lower gear is fixedly installed at the working end of the side motor. A left rotating column is rotatably installed inside the bracket, and an upper gear is fixedly installed at the end of the left rotating column.

[0007] Preferably, the flipping frame is provided with a moving component, which includes horizontal hydraulic rods fixed to the top of both sides of the flipping frame, for driving the two sets of lower concave frames and the two sets of upper concave frames to move closer or further apart from each other.

[0008] Preferably, both the lower and upper recessed frames are rotatably equipped with bidirectional lead screws, and the outside of the bidirectional lead screws is provided with two sets of nut seats. The interior of both the upper and lower recessed frames is provided with sliding grooves, and a slider is fixedly provided at one end of the limiting plate.

[0009] Preferably, a motor is fixedly installed on the front side of both the upper and lower recessed frames.

[0010] Preferably, the interior of the flipping frame is provided with two sets of moving slots, and two sets of T-shaped sliding plates are fixedly installed on the front and back of the recessed frame.

[0011] Preferably, the bidirectional lead screw is provided with a protective component, which includes three sets of telescopic tubes sleeved on the outside of the bidirectional lead screw, three sets of limiting rods fixedly installed on the lower and upper concave frames, multiple sets of sliding rings sleeved on the outside of the limiting rods, and multiple sets of connecting rods fixedly installed between the sliding rings and the telescopic tubes.

[0012] Preferably, a limiting member is provided on the other side of the bracket. The limiting member includes a side block fixed to the other side of the bracket. A limiting hydraulic rod is fixedly provided inside the side block, and an arc-shaped plate is fixedly provided at the bottom working end of the limiting hydraulic rod.

[0013] Preferably, a telescopic pressure plate hydraulic cylinder is fixedly installed on the bracket.

[0014] Preferably, a lifting hydraulic cylinder is also fixedly installed on the bracket.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) The present invention uses a flipping mechanism and a side motor structure to automatically flip the clamped fabric 180 degrees, replacing manual flipping to complete double-sided patching, simplifying the process and avoiding the inefficiency caused by manual intervention. With the lifting hydraulic rod, the clamping distance can be adjusted according to the fabric thickness. At the same time, the flipping mechanism and the pushing hydraulic cylinder work together to realize automatic feeding and flipping to achieve integrated operation of double-sided patching.

[0016] (2) The present invention uses a designed moving component, in which a horizontal hydraulic rod drives the lower concave frame and the upper concave frame to move the limiting plate, which can stretch the fabric along the length direction of the fabric. A motor is installed in conjunction with a two-way screw and a nut seat to drive the limiting plate to stretch the fabric along the width direction of the fabric, so that the fabric can be stretched in both directions. The two-way stretching can eliminate wrinkles in the center patch area of ​​the fabric and ensure the flatness of the patch. At the same time, by adjusting the extension and retraction of the horizontal hydraulic rod and the rotation of the two-way screw, the distance between the limiting plates can also be adjusted. This can adapt to down jacket fabrics of different lengths and widths, and can not only flatten the fabric, but also adapt to down jacket fabrics of different lengths and widths. At the same time, flattening can also be achieved during the flipping process, avoiding wrinkles and unevenness in the patch area of ​​the fabric during the automatic feeding process of the conveyor, thus improving the versatility of the device.

[0017] (3) The present invention can fix the position of the flipping frame by designing limiting components, avoid the side motor from accidentally starting during the patching process and causing the flipping frame to rotate, prevent the fabric from shifting, ensure the patching position is accurate, and ensure that the fabric is in a stable state during patching by limiting the flipping frame, reducing problems such as patching offset caused by fabric shaking, improving patching quality, and avoiding equipment operation risks caused by accidental rotation of the flipping frame, thus enhancing operational safety.

Detailed Implementation

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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.

[0020] Example 1 Please see Figures 1-9 This invention provides a technical solution: an automatic patching device for down jacket fabric, comprising a base frame 105, a push hydraulic cylinder 106 fixed on the base frame 105, a support 100, and an arc-shaped concave plate 103 and a spherical protrusion 102 disposed on the support 100. Two sets of T-shaped rails are fixedly disposed on the top of the base frame 105, and the bottom of the support is slidably disposed on the T-shaped rails. A conveyor for conveying the fabric is disposed on the back of the device. By activating the push hydraulic cylinder 106, the working end of the hydraulic cylinder 106 is moved towards the back of the device, causing the support 100, the flipping frame 201, the upper concave frame 203, the lower concave frame 202, etc., to move towards the back as well. At this time, the limiting plates 206 on the upper concave frame 203 and the lower concave frame 202 enter the end of the conveyor (that is, the end of the conveyor is located between the limiting plates 206 on the upper concave frame 203 and the lower concave frame 202, conveying the fabric to the rubber plate 207 on top of the limiting plate 206 in the lower concave frame 202, realizing the feeding. Then, according to the reverse principle, the working end of the hydraulic cylinder 106 is pushed to extend towards the front of the equipment, driving the bracket 100 and the flipping frame 201 back to their original positions. At this time, the patching operation begins, realizing automated fabric conveying, and is used in conjunction with the production line. The bracket 100 is equipped with a flipping mechanism, which includes: Rotate the flipping frame 201 set on the bracket 100 to flip the down jacket fabric; The flipping frame 201 is equipped with two sets of upper concave frames 203 and two sets of lower concave frames 202. Each of the upper concave frames 203 and lower concave frames 202 is equipped with two sets of limiting plates 206. A rubber plate 207 is fixedly installed on the limiting plate 206 for clamping the down jacket fabric. The down jacket fabric is conveyed by a conveyor to the rubber plate 207 on the top of the limiting plate 206 on the two sets of lower concave frames 202. Then, the two sets of lifting hydraulic rods 205 are activated. The lifting hydraulic rods 205 can adjust the extension and retraction amount for fabrics of different thicknesses, changing the vertical distance between the limiting plates 206 in the upper concave frame 203 and the lower concave frame 202. The two sets of lifting hydraulic rods 205 drive the corresponding upper concave frame 203 to move downward, causing the limiting plate 206 in the upper concave frame 203 to descend, which in turn causes the corresponding bottom rubber plate 207 to descend and clamp the fabric. The rubber plate 207 can play a buffering role and protect the fabric. A lifting hydraulic rod 205 is provided between the upper concave frame 203 and the lower concave frame 202. The lifting hydraulic rod 205 is fixed on the lower concave frame 202 near the flip frame 201, and the working end of the lifting hydraulic rod 205 is fixedly connected to the bottom of the upper concave frame 203. It is used to adjust the vertical distance between the two sets of limiting plates 206 according to the different thicknesses of down jacket fabric. A side motor 200 is fixedly installed on one side of the bracket 100. After patching one side of the fabric, the side motor 200 can drive the flipping frame 201 to flip 180 degrees, thereby causing the clamped fabric to flip 180 degrees and patching the other side of the fabric. Then, the working end of the side motor 200 reverses 180 degrees, causing the flipping frame 201 and the fabric to reverse 180 degrees back to their original positions to complete the double-sided patching of the fabric. The working end of the side motor 200 is fixedly equipped with a lower gear, and the bracket 100 has a rotating left column inside. The end of the left column is fixedly equipped with an upper gear. The upper gear meshes with the lower gear. The working end of the side motor 200 drives the lower gear to rotate, which in turn drives the upper gear to rotate. The upper gear drives the left column to rotate, which in turn drives the flipping frame 201 and the right column 204 to rotate.

[0021] Example 2 Please refer to Example 1. Figures 1-3 , Figures 5-10The flip frame 201 is equipped with a moving component, which includes horizontal hydraulic rods 300 fixed to the top of both sides of the flip frame 201. Both the horizontal hydraulic rods 300 and the lifting hydraulic rods 205 are connected to an external hydraulic station via hoses. The working end of the horizontal hydraulic rods 300 is fixedly connected to the side of the lower concave frame 202, used to drive the two sets of lower concave frames 202 and the two sets of upper concave frames 203 to move closer or further apart, achieving lateral stretching of the middle part of the down jacket fabric. Since the upper concave frame 203 is connected to the lower concave frame 202 via the lifting hydraulic rods 205, the movement of the lower concave frame 202 will affect the movement of the upper concave frame 203. The synchronous movement causes multiple sets of upper and lower limiting plates 206 to exert a lateral pulling force on the clamped fabric, achieving lateral stretching of the middle part of the fabric. At the same time, the movement of the upper and lower limiting plates 206 can also clamp fabrics of different lengths before clamping. When the fabric length is long or short, the upper concave frame 203 and lower concave frame 202 on the left side of the flip frame 201 move away from or closer to the corresponding upper concave frame 203 and lower concave frame 202 on the right side of the flip frame 201, thereby causing the corresponding limiting plate 206 to move. After moving to the appropriate length of the fabric, the fabric is clamped and fixed. Both the lower concave frame 202 and the upper concave frame 203 are rotatably equipped with bidirectional lead screws 305. Two sets of nut seats 304 are provided on the outside of the bidirectional lead screws 305. Sliding grooves are opened inside the upper concave frame 203 and the lower concave frame 202. A slider 306 is fixedly provided at one end of the limiting plate 206, and the end of the slider 306 passes through the inside of the sliding groove. The slider 306 slides in the sliding groove, which increases the stability of the two sets of limiting plates 206 on the upper concave frame 203 and the lower concave frame 202 when they are close to or far from each other. A motor 303 is fixedly installed on the front of both the upper concave frame 203 and the lower concave frame 202. An electric slip ring is installed on the right rotating shaft. The rotating end of the electric slip ring is connected to the motor 303 through a line, and the stationary end of the electric slip ring is connected to an external power supply to provide power to the motor 303. The motor 303 can drive the bidirectional lead screw 305 to rotate forward or backward, thereby causing the two sets of nut seats 304 on the bidirectional lead screw 305 to move closer or further away from each other. This causes the two sets of limiting plates 206 on the upper concave frame 203 or the lower concave frame 202 to move closer or further away from each other, stretching the fabric (in the fabric width direction) to make it flat. At the same time, this method can also be used to adjust the fabric according to different widths before clamping the fabric, increasing its applicability. The working end of the motor 303 is fixedly connected to the end of the bidirectional lead screw 305. The interior of the tilting frame 201 is also provided with two sets of moving slots 301. Two sets of T-shaped sliding plates 302 are fixedly installed on the front and back of the recessed frame 202, and these T-shaped sliding plates 302 slide within the moving slots 301. This increases the restriction, guidance, and stability of the recessed frame 202 when it moves left and right via the horizontal hydraulic rods 300. Simultaneously, the two sets of horizontal hydraulic rods 300 on the tilting frame 201 drive the corresponding recessed frames 202 to move, allowing the two sets of recessed frames 202 to move in opposite directions. When moving in opposite directions (i.e., the recessed frame 202 on the left side of the tilting frame 201 moves to the left, and the recessed frame 202 on the right side of the tilting frame 201 moves to the right), it can drive the corresponding limiting... The positioning plate 206 moves along with the fabric, stretching the clamped fabric to both sides of the flipping frame 201, stretching the fabric in the length direction to make it flat. Through simultaneous stretching in the width and length directions, the center part of the fabric (the area to be patched) can be stretched and flattened, facilitating subsequent patching operations in the center. This allows the area of ​​the fabric to be patched to be stretched and flattened while the fabric is clamped or flipped (for example, some fabrics are thick and the upper surface is flat, but the lower surface is uneven and contains wrinkles; stretching and flattening the fabric while flipping it can flatten the wrinkles on the lower surface). This facilitates the patching operation.

[0022] Example 3 Please refer to Example 2. Figure 5 , Figure 6 , Figure 7 , Figure 9 and Figure 10The double-acting screw 305 is externally fitted with protective components, including three sets of telescopic tubes 500 sleeved around the double-acting screw 305. Two sets are short-distance, and one set is long-distance. The two ends of the short-distance telescopic tubes 500 are fixedly connected to the upper concave frame 203, the lower concave frame 202, and the nut seat 304, respectively. The two ends of the long-distance telescopic tubes 500 are fixedly connected to the nut seat 304. Three sets of limiting rods 501 are fixedly installed on the lower concave frame 202 and the upper concave frame 203. The ends of the limiting rods 501 pass through the interior of the limiting plate 206. Multiple sets of sliding rings 502 are sleeved on the outside of the limiting rods 501. When the limiting plates 206 move closer or further apart, the telescopic tubes 500 begin to extend and retract. The tube 500 can prevent some cotton fibers or fabric from adhering to the surface of the bidirectional lead screw 305, which would cause the cotton fibers or fabric to get tangled on the bidirectional lead screw 305, damaging the fabric and causing wear to the bidirectional lead screw 305. It also affects the movement of the nut seat 304, ensuring smooth movement of the nut seat 304 and improving the stability of the device operation. At the same time, the sliding ring 502 slides on the limiting rod 501, which can pull the telescopic tube 500 outward, preventing the inner wall of the telescopic tube 500 from contacting the outer wall of the rotating bidirectional lead screw 305 and causing wear to the outer wall of the bidirectional lead screw 305 and the inner wall of the telescopic tube 500. Multiple sets of connecting rods are fixedly installed between the sliding ring 502 and the telescopic tube 500.

[0023] Example 4 Please refer to Example 3. Figures 1-4 On the other side of the bracket 100, a limiting component is provided, including a side block 400 fixed to the other side of the bracket 100. A limiting hydraulic rod 401 is fixedly provided inside the side block 400. An arc plate 402 is fixedly provided at the bottom working end of the limiting hydraulic rod 401. The inner wall of the arc plate 402 contacts the outer wall of the right-turning column 204. When the flipping frame 201 is patched before flipping, patched after flipping, or for fabrics that only need to be patched on one side, the limiting hydraulic rod 401 can drive the arc plate 402 to move downward and contact the right-turning column 204 during the patching process, and clamp and limit it, so as to prevent the side motor 200 from starting unexpectedly during the patching process, which would cause the flipping frame 201 and the fabric to rotate, affecting the patching effect and patching quality.

[0024] In this embodiment, a telescopic pressing hydraulic cylinder 104 is fixedly installed on the bracket 100, and the bottom working end of the telescopic pressing hydraulic cylinder 104 is fixed to the arc-shaped concave plate 103.

[0025] In this embodiment, a lifting hydraulic cylinder 101 is also fixedly installed on the bracket 100. The top working end of the lifting hydraulic cylinder 101 is fixed to the spherical protrusion 102. The lifting hydraulic cylinder 101 drives the spherical protrusion 102 to move upward, so that its top contacts the center part of the fabric. Then, the telescopic pressing hydraulic cylinder 104 drives the arc-shaped concave plate 103 to move downward, causing the patch (label, etc.) located on the inner wall of the arc-shaped concave plate 103 to move downward and contact the center part of the fabric and apply pressure, thereby attaching the patch (label, etc.) to the center part of the fabric.

[0026] Working principle and usage process of this invention: When using this invention, the installation motor 303 is started according to the width of the fabric to be processed. The installation motor 303 drives the bidirectional lead screw 305 to rotate, which drives the two sets of limiting plates 206 to move closer or further apart through the nut seat 304, adjusting the spacing to match the fabric width. According to the fabric length, the horizontal hydraulic rod 300 is started, driving the two sets of lower concave frames 202 and upper concave frames 203 to move closer or further apart, thereby moving the limiting plates 206. At this time, the T-shaped sliding plate 302 slides in the moving groove 301 of the flipping frame 201 to ensure smooth movement and adjust to the position to match the fabric length. The hydraulic cylinder 106 is activated to move the support 100 toward the back of the equipment. Then, the down jacket fabric is conveyed via a conveyor to the rubber plate 207 on the top of the limiting plate 206 on the two sets of lower concave frames 202. Next, the hydraulic cylinder 106 moves the support 100 back to its original position. Then, the lifting hydraulic rod 205 is activated to push the upper concave frame 203 downwards, causing the limiting plate 206 and rubber plate 207 on the upper concave frame 203 to engage with the corresponding components on the lower concave frame 202. The fabric is clamped and fixed. The extension and retraction of the lifting hydraulic rod 205 are finely adjusted according to the fabric thickness to ensure stable clamping without damaging the fabric. When the upper surface of the fabric to be patched is uneven, or when both the upper and lower surfaces of the fabric to be patched are uneven, the four mounting motors 303 are activated, driving the corresponding bidirectional lead screws 305 to rotate, driving the limiting plates 206 to move away from each other, and stretching the fabric in the width direction. At the same time, the horizontal hydraulic rod 300 is activated, driving the two sets of lower concave frames 202 and the two sets of upper concave frames 203 to move away from each other. The fabric is stretched along its length to achieve a smooth surface in the center of the patch area. If, due to the fabric's thickness, only the lower surface patch area is uneven, after patching the upper surface, the fabric is flipped on the flipping frame 201. Before patching the lower surface, the same method is used to smooth the uneven upper surface patch area or both the upper and lower surfaces. This process ensures the lower surface is smoothed during the flipping process. During the process, the telescopic tube 500 outside the double-acting screw 305 extends and retracts with the movement of the limiting plate 206. The sliding ring 502 slides on the limiting rod 501 to prevent the telescopic tube 500 from contacting and wearing with the double-acting screw 305. At the same time, due to the extension and retraction of the telescopic tube 500, the sliding ring 502 is driven to slide on the limiting rod 501 through the connecting rod, generating an outward pulling force on the telescopic tube 500 to prevent the inner wall of the telescopic tube 500 from contacting the outer wall of the double-acting screw 305, which would cause wear on the inner wall of the telescopic tube 500 and the outer wall of the double-acting screw 305. When applying the patch to one side of the fabric, activate the limiting hydraulic rod 401 inside the side block 400 to push the arc plate 402 downward to clamp the right-turning column 204, fix the flipping frame 201, place the patch on the inner wall of the arc concave plate 103, activate the lifting hydraulic cylinder 101 to push the spherical protrusion 102 upward to lift the fabric patch area and provide support; activate the telescopic pressing hydraulic cylinder 104 to push the arc concave plate 103 downward to bring the patch into contact with the fabric and apply pressure, thus completing the patching of one side. When patching both sides of the fabric, after patching one side of the fabric, close the limiting hydraulic rod 401, the arc plate 402 disengages from the right rotating column 204, start the side motor 200, drive the flipping frame 201 and the right rotating column 204 to rotate 180 degrees, causing the clamped fabric to flip synchronously. Then, start the limiting hydraulic rod 401 again to clamp the right rotating column 204. Repeat the above steps for patching one side of the fabric to complete the patching work on the other side of the fabric. After the patching of both sides of the fabric is completed, the side motor 200 reverses to drive the flipping frame 201 to reset, the lifting hydraulic rod 205 retracts to drive the upper concave frame 203 to move upward, release the fabric and remove it.

[0027] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
