Description

Seamless underwear fabric one-time forming and cutting equipment Technical Field

[0001] This utility model relates to the field of one-time forming and cutting technology, and in particular to one-time forming and cutting equipment for seamless underwear fabric. Background Technology

[0002] The edge of the bra is so seamless that you can't see any bra lines when you wear it. That's the concept of seamless underwear. So-called "seamless underwear" is underwear that is basically made in one piece by using new and special equipment through weft knitting. It uses high-tech production of high-elastic knitted outerwear, underwear and high-elastic sportswear, so that there are no seams in the neck, waist and hip areas. Only the crotch area needs to be patched as a post-processing. Due to the special process requirements of seamless underwear, it needs to be cut into one piece during processing.

[0003] Common seamless underwear fabric one-time forming and cutting equipment only includes the function of one-time forming and cutting. It can cut seamless underwear fabric in one step, but it lacks the function of protecting the blade. It cannot guarantee the cutting quality. During the pressing process, the blade may deform and become distorted due to excessive or uneven force, which will change the shape of the cut fabric and affect the cutting quality.

[0004] Therefore, given that the aforementioned seamless underwear fabric one-time forming and cutting equipment lacks protection for the cutting tools, and is prone to deformation and deviation of the cutting body due to uneven force during high-pressure operation, resulting in an increased cutting contour error rate and causing problems such as burrs and dimensional deviations on the fabric edges, there is an urgent need to design a new type of seamless underwear fabric one-time forming and cutting equipment. Summary of the Invention

[0005] To overcome the shortcomings of common seamless underwear fabric one-time forming and cutting equipment, which lacks protection for the cutting blades and is prone to deformation and displacement of the blade body due to uneven force during high-pressure operation, resulting in increased cutting contour error rate and causing problems such as burrs and dimensional deviations on the fabric edges.

[0006] The technical solution of this utility model is as follows: a seamless underwear fabric one-time forming and cutting equipment, including a supporting top plate, a lower pressure connecting plate, a connecting plate, an underwear outline plate, an underwear outline blade, a telescopic rod, and a blade inner support plate. The lower pressure connecting plate is arranged below the supporting top plate. Three connecting plates of different shapes are arranged around the lower pressure connecting plate. The underwear outline plate is arranged at the bottom of the lower pressure connecting plate. The three connecting plates of different shapes are all fixed to the underwear outline plate by bolts. The underwear outline blade is arranged at the bottom edge of the underwear outline plate. The telescopic rod is arranged in the middle of the bottom of the underwear outline plate. The blade inner support plate is arranged at the bottom end of the telescopic rod corresponding to the position of the underwear outline blade.

[0007] Preferably, the underwear outline plate is driven downward by a drive cylinder. The underwear outline plate then drives the underwear outline blade and the blade inner support plate to move downward synchronously. During the downward movement, the blade inner support plate first contacts the seamless underwear fabric and presses it down. Then, the underwear outline blade continues to move downward. At this time, the telescopic rod and spring are compressed under pressure until the blade tip at the bottom of the underwear outline blade is inserted into the underwear-shaped blade groove. During this process, the underwear outline blade cuts the seamless underwear fabric, and the blade inner support plate is located inside the underwear outline blade. The blade inner support plate limits the shape of the underwear outline blade, thereby preventing the blade from deforming or shifting due to force, thus achieving the protection function of the blade.

[0008] Preferably, the outer diameter of the inner support plate of the blade is the same as the inner diameter of the underwear-shaped blade, and a rubber strip is provided at the bottom edge of the inner support plate of the blade.

[0009] Preferably, the telescopic rod is fitted with spring components all around its body, with the bottom end of the spring components welded to the top of the inner support plate of the blade, and the top end of the spring components welded to the bottom of the outer panel of the underwear.

[0010] Preferably, a drive cylinder is provided at the center of the top of the support plate, and the piston end of the drive cylinder passes through the support plate and connects to the top of the lower connecting plate.

[0011] Preferably, four L-shaped support rods are provided at the four corners of the bottom of the support top plate, and the bottom ends of the four L-shaped support rods are connected to the support base plate. The top of the support base plate is provided with a storage groove.

[0012] Preferably, two limiting rods are provided on the left and right sides of the bottom of the storage compartment, and two limiting plates are provided on the left and right sides of the underwear outer panel, with the limiting plates and limiting rods slidably connected.

[0013] Preferably, the bottom of the storage compartment is provided with an underwear-shaped blade groove corresponding to the position of the underwear-shaped blade, and four support legs are provided at the four corners of the bottom of the support base plate.

[0014] The beneficial effects of this utility model are:

[0015] 1. The fabric is cut by fully cutting into the lingerie-shaped groove with the blade edge. During this process, the inner support plate of the blade is always nested in the inner cavity of the lingerie-shaped blade and maintains a clearance fit with it. Its high-strength alloy material provides radial support to the side wall of the blade, suppressing the deformation and deviation of the tool caused by the shearing force of the fabric during the cutting operation, and ensuring that the cutting line accuracy is controlled within the specified range.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to Figures 1-5. This utility model provides an embodiment of a seamless underwear fabric one-time forming and cutting device, including a supporting top plate 1, a pressing connecting plate 2, a connecting plate 3, an underwear outline plate 4, an underwear outline blade 5, a telescopic rod 6, and a blade inner support plate 7. The pressing connecting plate 2 is arranged below the supporting top plate 1. Three connecting plates 3 of different shapes are arranged around the pressing connecting plate 2. The underwear outline plate 4 is arranged at the bottom of the pressing connecting plate 2. The three connecting plates 3 of different shapes are all fixed to the underwear outline plate 4 by bolts. The underwear outline blade 5 is arranged at the bottom edge of the underwear outline plate 4. The telescopic rod 6 is arranged in the middle of the bottom of the underwear outline plate 4. The blade inner support plate 7 is arranged at the bottom end of the telescopic rod 6 corresponding to the position of the underwear outline blade 5. The cylinder 10 applies a vertically downward driving force to the underwear shape plate 4, which simultaneously drives the underwear shape blade 5 and the inner support plate 7 fixed on it to move downward as a whole. In the initial stage of movement, the inner support plate 7 first contacts the surface of the seamless underwear fabric and completes full-area compression. Subsequently, under continuous pressure, the underwear shape blade 5 compresses the telescopic rod 6 and the spring 9 to produce elastic deformation, driving the blade to accurately pierce into the underwear-shaped blade groove 16 to complete the fabric cutting. During this process, the inner support plate 7 is nested in the inner cavity of the underwear shape blade 5. Through its high-strength support surface, it implements three-dimensional constraints on the blade shape, effectively suppressing the lateral deviation of the blade caused by the difference in resistance between fabric layers, thereby maintaining the linear accuracy of the cutting trajectory and the quality of the cross-section.

[0024] Please refer to Figures 2-5. In this embodiment, the outer diameter of the inner support plate 7 is the same as the inner diameter of the underwear-shaped blade 5. A rubber strip 8 is provided at the bottom edge of the inner support plate 7. The inner support plate 7 defines the shape of the underwear-shaped blade 5, thereby preventing the blade from deforming and shifting under force. The inner support plate 7 holds the seamless underwear fabric in place. A spring 9 is fitted around the telescopic rod 6. The bottom end of the spring 9 is welded to the top of the inner support plate 7, and the top end of the spring 9 is welded to the bottom of the underwear-shaped plate 4. When not moving downwards, the inner support plate 7 of the blade is pushed downwards by the thrust of the spring member 9, so that the position of the inner support plate 7 of the blade is below the underwear shape blade 5. This ensures that the inner support plate 7 of the blade always contacts the seamless underwear fabric before the cutting component moves downwards. A drive cylinder 10 is set at the center of the top of the support plate 1. The piston end of the drive cylinder 10 passes through the support plate 1 and is connected to the top of the pressing connecting plate 2. The drive cylinder 10 drives the underwear shape plate 4 to move downwards, and the underwear shape plate 4 drives the underwear shape blade 5 and the inner support plate 7 of the blade to move downwards synchronously.

[0025] Please refer to Figures 1-5. In this embodiment, four L-shaped support rods 11 are provided at the four corners of the bottom of the support top plate 1. The bottom ends of the four L-shaped support rods 11 are connected to the support base plate 12. The top of the support base plate 12 is provided with a storage groove 13. The seamless underwear fabric is placed inside the storage groove 13. Two limiting rods 14 are provided on the left and right sides of the bottom of the storage groove 13. Two limiting plates 15 are provided on the left and right sides of the underwear shape plate 4. The limiting plates 15 are slidably connected to the limiting rods 14. During the movement of the underwear shape plate 4, the limiting plates 15 are slidably connected to the limiting rods 14. The bottom of the storage groove 13 is provided with an underwear-shaped cutting groove 16 corresponding to the position of the underwear shape blade 5. Four support legs 17 are provided at the four corners of the bottom of the support base plate 12. The blade edge of the underwear shape blade 5 is inserted into the underwear-shaped cutting groove 16. During this process, the underwear shape blade 5 cuts the seamless underwear fabric.

[0026] During operation, after the seamless underwear fabric is positioned inside the storage slot 13, the drive cylinder 10 is activated to generate a vertical axial driving force, pushing the underwear shape plate 4 downward along the guide trajectory of the limiting rod 14. The underwear shape plate 4, through a rigid connection, synchronously drives the underwear shape blade 5 and the blade inner support plate 7 to perform a compound motion. In the initial stage of operation, the bottom surface of the blade inner support plate 7 first contacts the fabric and applies a uniform preload. As the drive cylinder 10 continues to supply energy, the underwear shape blade 5 overcomes the elastic resistance of the telescopic rod 6 and the spring 9 to penetrate the fabric layer. Finally, the blade edge is precisely embedded in the underwear-shaped blade groove 16 to complete the cutting path. During this process, the blade inner support plate 7 is always fitted in a clearance fit with the inner cavity of the underwear shape blade 5. Its high-rigidity alloy structure implements three-dimensional constraints on the lateral deformation of the blade, effectively offsetting the asymmetric shear stress generated during the fabric cutting process, so that the maximum offset of the blade is controlled within the specified range, achieving the dual technical effects of strengthening the stability of the blade shape and improving the cutting quality.

[0027] Through the above steps, the driving cylinder 10 applies a vertical driving force to the underwear shape plate 4, causing the underwear shape blade 5 and the blade inner support plate 7 to move downwards synchronously. The blade inner support plate 7 preferentially contacts the seamless underwear fabric and applies a pre-compression force. The underwear shape blade 5 overcomes the elastic resistance of the telescopic rod 6 and the spring 9 to continuously penetrate the fabric layer until the blade edge is embedded in the underwear-shaped cutting groove 16 to complete the cutting. During this process, the blade inner support plate 7 forms a clearance fit with the underwear shape blade 5 in an embedded form. Through its high-strength support structure, it applies a radial constraint force to the side wall of the blade, offsetting the asymmetric shear stress during the cutting process, and positioning the blade... The deformation is suppressed within the specified range to achieve shape stability control under dynamic operation of the tool. This solves the problem of common seamless underwear fabric one-time forming and cutting equipment, which only has the function of one-time forming and cutting. It can cut seamless underwear fabric in one step, but lacks the function of protecting the tool. When the underwear shape blade 5 is subjected to the combined load of vertical downward pressure and transverse shear force, the blade body is easily plastically deformed due to the non-uniform stress distribution. This causes the blade trajectory to deviate from the preset cutting path, resulting in serrated burrs and out-of-tolerance contour dimensions at the cutting edge, which directly affects the flatness and dimensional accuracy of the finished product seam.
