Description

Technical Field

[0001] This invention relates to the field of fabric processing technology, specifically to a transport system for preventing inward curling of polyester-cotton knitted elastic fabric. Background Technology

[0002] Polyester-cotton knitted fabric, as the name suggests, refers to knitted fabric woven from blended yarns of polyester and cotton, typically using a ratio of 60% polyester to 40% cotton or 80% polyester to 20% cotton. Polyester-cotton knitted fabric combines the advantages of both polyester and cotton fabrics. This fabric exhibits excellent abrasion resistance under both dry and wet conditions, is dimensionally stable with a low shrinkage rate, has a three-dimensional feel, is not easily wrinkled, and is easy to wash and dry.

[0003] When using polyester-cotton knitted fabric to prepare items, overlocking is required. Due to the good elasticity of the fabric, the edges of the polyester-cotton knitted elastic fabric always curl during overlocking. The curled edges are not easy to align, making fabric processing more troublesome. To address this issue, we propose an anti-inward curling transport system for polyester-cotton knitted elastic fabric. Summary of the Invention

Detailed Implementation

[0027] 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.

[0028] Example: Figure 1-8 As shown, the present invention provides an anti-inward curling transport system for polyester-cotton knitted elastic fabric, including a first side frame 1 and a second side frame 2. The first side frame 1 is provided with an automatic feeding roller 3, and a tubular polyester-cotton knitted elastic fabric is sleeved on the automatic feeding roller 3. A guide bottom roller 4 and a guide top roller 5 are provided on the side of the first side frame 1 and the second side frame 2 near the automatic feeding roller 3. An anti-inward curling mechanism 6 is fixedly installed on the side of the first side frame 1 and the second side frame 2 near the guide top roller 5. A glue injection mechanism 7 is fixedly installed on one side of the anti-inward curling mechanism 6. The two anti-inward curling mechanisms 6 and the two glue injection mechanisms 7 are symmetrically arranged. A pressure heating assembly 8 is provided on the side of the first side frame 1 and the second side frame 2 away from the automatic feeding roller 3. In use, the polyester-cotton knitted elastic fabric at the end of the tubular polyester-cotton knitted elastic fabric passes around the bottom of the guide bottom roller 4 and the top of the guide top roller 5, passes through the two anti-inward curling mechanisms 6 and the two glue injection mechanisms 7, and passes through the pressure heating assembly 8.

[0029] The anti-inward curling mechanism 6 includes a mounting base 61. Each anti-inward curling mechanism 6 is fixedly mounted on the side of the corresponding first side frame 1 and second side frame 2 near the automatic feeding roller 3 via the mounting base 61. An adjusting top frame 62 is slidably mounted on the top of the mounting base 61. A side limiting plate 63 is fixedly mounted on one side of the top of the adjusting top frame 62. An anti-curling inclined frame 64 is integrally formed at one end of the adjusting top frame 62 near the side limiting plate 63. The anti-curling inclined frame 64 is an L-shaped inclined structure. A pressure plate 65 is provided at the top of the side limiting plate 63. The lower surface of the pressure plate 65 contacts the top of the anti-curling inclined frame 64. A rotating seat 66 is fixedly installed on the side end. A bearing 661 is fixedly clamped on the top of the rotating seat 66. A rotating shaft 67 is fixedly inserted in the middle of the bearing 661. The rotating shaft 67 is fixedly installed on the side end of the pressure plate 65. The pressure plate 65 can rotate at the top of the side limiting plate 63. A protective sleeve 68 is fixedly installed on the side of the rotating seat 66 away from the side limiting plate 63. The end of the rotating shaft 67 away from the pressure plate 65 extends into the protective sleeve 68. A torsion spring 69 is provided between the rotating shaft 67 and the protective sleeve 68. When the rotating shaft 67 rotates, the torsion spring 69 forces the pressure plate 65 to rotate towards the side closer to the anti-rolling edge inclined frame 64.

[0030] A threaded rod 611 is fixedly installed on the upper end of the mounting base 61. An adjustment groove 621 corresponding to the threaded rod 611 is opened on the adjusting top frame 62. The top of the threaded rod 611 passes through the adjustment groove 621 and is threaded with a positioning nut 612. In use, by loosening the positioning nut 612, the adjusting top frame 62 is slid to adjust the distance between the two anti-rolling edge brackets 64 until the edge of the polyester-cotton knitted elastic fabric is placed between the two anti-rolling edge brackets 64 and the pressure plate 65. The pressure plate 65 limits the upper surface of the edge of the polyester-cotton knitted elastic fabric, and the side limiting plate 63 limits the polyester-cotton knitted elastic fabric. When conveying polyester-cotton knitted elastic fabric, the L-shaped inclined anti-rolling frame 64, in conjunction with the limiting pressure plate 65, can continuously and automatically flatten the inward rolled edge of the polyester-cotton knitted elastic fabric. Since the pressure plate 65 can rotate, when encountering thicker cotton knitted elastic fabric, the pressure plate 65 rotates, driving the rotating shaft 67 to rotate. Through the torsion spring 69, the pressure plate 65 is forced to rotate towards the side closer to the anti-rolling frame 64, limiting the upper surface of the edge of the polyester-cotton knitted elastic fabric. This allows for the automatic flattening of the inward rolled edge of cotton knitted elastic fabrics of different thicknesses.

[0031] The glue injection mechanism 7 includes a mounting base 71, which is fixedly mounted on a side limiting plate 63. A rotating base 72 is fixedly mounted on the side of the mounting base 71 away from the side limiting plate 63. A rotating top frame 73 is provided at the top of the rotating base 72. A glue injection bottom cylinder 74 is rotatably mounted in the middle of the rotating base 72. A glue injection top cylinder 75 is rotatably mounted in the middle of the rotating top frame 73. A plurality of glue injection holes 751 are evenly distributed on the glue injection top cylinder 75. A sealing rotating element 752 is provided at the end of the glue injection top cylinder 75. A glue inlet pipe 753 is provided in the middle of the sealing rotating element 752. By setting a sealing rotating component 752, the rotation of the glue injection bottom cylinder 74 and the glue injection top cylinder 75 does not affect the fixed position of the glue inlet pipe 753. Thus, the setting glue is stably injected into the rotating glue injection bottom cylinder 74 and the glue injection top cylinder 75 through the glue inlet pipe 753. The edge of the polyester-cotton knitted elastic fabric with the inner rolled edge automatically flattened is placed between the glue injection bottom cylinder 74 and the glue injection top cylinder 75. The setting glue in the glue injection bottom cylinder 74 and the glue injection top cylinder 75 is discharged through multiple glue injection holes 751 and soaks into the edge of the polyester-cotton knitted elastic fabric, so as to flatten and set the edge of the polyester-cotton knitted elastic fabric.

[0032] A first slide cylinder 76 is fixedly installed at the top of the rotating base 72. A first card holder 761 is slidably engaged in the middle of the first slide cylinder 76. The top of the first card holder 761 and the bottom of the rotating top frame 73 are fixedly installed. A first spring 762 is fixedly installed between the bottom of the first card holder 761 and the inner lower wall of the first slide cylinder 76. By setting the first card holder 761, the first slide cylinder 76 and the first spring 762, when the polyester-cotton knitted elastic fabric becomes thicker, the glue injection top cylinder 75 and the rotating top frame 73 move upward, causing the first card holder 761 to move upward in the first slide cylinder 76 and pull the first spring 762. Through the reaction force of the first spring 762, the glue injection top cylinder 75 is always close to the glue injection bottom cylinder 74, so that the polyester-cotton knitted elastic fabric is always clamped between the glue injection top cylinder 75 and the glue injection bottom cylinder 74 for stable glue impregnation.

[0033] An auxiliary slide frame 77 is fixedly installed on the side of the rotating base 72 away from the mounting seat 71. An auxiliary slide block 771 is slidably engaged in the middle of the auxiliary slide frame 77. A second mounting block 772 is fixedly installed on one side of the auxiliary slide block 771. A second slide cylinder 773 is slidably sleeved on the outer side of the second mounting block 772. The side of the second slide cylinder 773 away from the second mounting block 772 is fixedly installed on the inner wall of the auxiliary slide frame 77. A second spring 774 is fixedly installed between the side of the second mounting block 772 away from the auxiliary slide block 771 and the inner wall of the second slide cylinder 773.

[0034] A first auxiliary shaft 78 is rotatably mounted in the middle of the auxiliary slide block 771. An auxiliary block 79 is fixedly mounted in the middle of the bottom end of the rotating top frame 73. A second auxiliary shaft 791 is rotatably mounted in the middle of the auxiliary block 79. A first gear 792 is fixedly sleeved on the outer side of the second auxiliary shaft 791. A second gear 793, which meshes with the first gear 792, is fixedly sleeved on the end of the glue injection top cylinder 75. A first sprocket 781 is fixedly sleeved on the outer side of the first auxiliary shaft 78. A second sprocket 782 is fixedly sleeved on the end of the glue injection bottom cylinder 74. A third sprocket 794 is fixedly sleeved on the end of the second auxiliary shaft 791. A transmission chain 783 meshes with the outer sides of the first sprocket 781, the second sprocket 782, and the third sprocket 794. When the polyester-cotton knitted elastic fabric thickens, the glue injection top cylinder 75, the rotating top frame 73, the first gear 792, the second auxiliary shaft 791, the second gear 793, and the third sprocket 794 move upwards. Through the connection of the transmission chain 783, the first... The sprocket 781, the first auxiliary shaft 78, and the auxiliary slide block 771 move towards the side closer to the rotating base frame 72. The second card seat 772 slides and pulls the second spring 774. Through the reaction force of the second spring 774, the auxiliary slide block 771 always moves away from the rotating base frame 72. The first sprocket 781 always pulls the transmission chain 783, so that the transmission chain 783 always meshes with the outside of the first sprocket 781, the second sprocket 782, and the third sprocket 794. Thus, by driving the second sprocket 782 to rotate, the first sprocket 781 and the third sprocket 794 rotate synchronously, which in turn drives the first auxiliary shaft 78 and the second auxiliary shaft 791 to rotate synchronously. Thus, through the first gear 792 and the second gear 793, the glue injection top cylinder 75 and the glue injection bottom cylinder 74 rotate synchronously in opposite directions. Thus, the glue injection top cylinder 75 and the glue injection bottom cylinder 74 perform rolling transmission of the polyester-cotton knitted elastic fabric and uniformly impregnate the polyester-cotton knitted elastic fabric with glue.

[0035] A third auxiliary shaft 710 is rotatably mounted on the side of the rotating base 72 near the mounting seat 71. A third gear 711 is fixedly sleeved on the outer side of the third auxiliary shaft 710. A fourth gear 712, which meshes with the third gear 711, is fixedly sleeved on the outer side of the end of the glue injection base cylinder 74. A retaining shaft 713 is fixedly mounted on the end of the third auxiliary shaft 710. A sleeve shaft 714 is slidably engaged on the outer side of the retaining shaft 713. The end of the sleeve shaft 714 is rotatably mounted on the corresponding first side frame 1 and second side frame 2. When the distance between the two anti-rolling edge inclined frames 64 is adjusted, the mounting seat 71 drives the retaining shaft 713 to slide in the sleeve shaft 714. Thus, by driving the sleeve shaft 714 to rotate, the retaining shaft 713 is always driven to rotate, thereby driving the third auxiliary shaft 710 to rotate, which in turn drives the third gear 711 to rotate, which in turn drives the fourth gear 712 and the glue injection base cylinder 74 to rotate synchronously in opposite directions.

[0036] The pressing and heating assembly 8 includes two pressing rollers 81 symmetrically distributed vertically. The pressing rollers 81 are rotatably mounted on the side of the first side frame 1 and the second side frame 2 away from the automatic feeding roller 3. The ends of the two pressing rollers 81 are fixedly fitted with transmission gears 82, which mesh with each other. A heating column 83 is fixedly clamped on the side of the pressing rollers 81 near the glue injection bottom cylinder 74. A belt pulley drive assembly 9 is fixedly fitted between the end of the top pressing roller 81 and the end of the sleeve shaft 714. The belt pulley drive assembly 9 includes two pulleys and a belt that is movably fitted onto the two belts. The drive belt on the outside of the wheel has two pulleys that are fixedly sleeved on the end of the top pressing roller 81 and the end of the sleeve shaft 714, respectively. In use, the polyester-cotton knitted elastic fabric after being impregnated with glue passes between the two pressing rollers 81. The glue impregnation position corresponds to the heating column 83. By controlling the external drive mechanism, the top pressing roller 81 is driven to rotate. With the meshing connection of the two drive gears 82, the bottom pressing roller 81 is driven to rotate in the opposite direction, so as to continuously convey the polyester-cotton knitted elastic fabric by roller. In addition, the belt pulley drive group 9 is used to drive the sleeve shaft 714 to rotate synchronously.

[0037] Working principle: When in use, the polyester-cotton knitted elastic fabric at the end of the tubular polyester-cotton knitted elastic fabric passes around the bottom of the guide bottom roller 4 and the top of the guide top roller 5, passes through the two anti-inward curling mechanisms 6 and the two glue injection mechanisms 7, and passes between the two pressing rollers 81 in the pressing and heating assembly 8.

[0038] By loosening the positioning nut 612, the top frame 62 is slidably adjusted, and the distance between the two anti-rolling edge inclined frames 64 is adjusted until the edge of the polyester-cotton knitted elastic fabric is placed between the two anti-rolling edge inclined frames 64 and the pressure plate 65. The pressure plate 65 limits the upper surface of the edge of the polyester-cotton knitted elastic fabric, and the side limiting plate 63 limits the side edge of the polyester-cotton knitted elastic fabric. When the polyester-cotton knitted elastic fabric is transferred, the L-shaped inclined anti-rolling edge inclined frame 64 cooperates with the limiting of the pressure plate 65. When the distance between the two anti-rolling edge inclined frames 64 is adjusted, the mounting base 71 drives the locking shaft 713 to slide in the sleeve shaft 714, thereby driving the sleeve shaft 714 to rotate, which in turn drives the locking shaft 713 to rotate.

[0039] The external drive mechanism is controlled to drive the top pressing roller 81 to rotate. In conjunction with the meshing connection of two transmission gears 82, the bottom pressing roller 81 is driven to rotate in the opposite direction, providing continuous roller conveying of the polyester-cotton knitted elastic fabric. In addition, the belt pulley drive group 9 drives the sleeve shaft 714 to rotate in sync, which drives the clamping shaft 713 to rotate, thereby driving the third auxiliary shaft 710 to rotate, which in turn drives the third gear 711 to rotate, which in turn drives the fourth gear 712, the glue injection bottom cylinder 74, and the second sprocket 782 to rotate in sync in the opposite direction, which drives the first sprocket 781 and the third sprocket 794 to rotate in sync, which in turn drives the first auxiliary shaft 78 and the second auxiliary shaft 791 to rotate in sync, thereby driving the glue injection top cylinder 75 and the glue injection bottom cylinder 74 to rotate in sync in the opposite direction through the first gear 792 and the second gear 793.

[0040] When conveying polyester-cotton knitted elastic fabric, the L-shaped inclined anti-rolling frame 64, in conjunction with the limiting position of the pressure plate 65, can continuously and automatically flatten the inward rolled edge of the polyester-cotton knitted elastic fabric. The automatically flattened edge of the polyester-cotton knitted elastic fabric is placed between the glue injection bottom cylinder 74 and the glue injection top cylinder 75. The setting glue in the glue injection bottom cylinder 74 and the glue injection top cylinder 75 is discharged through multiple glue injection holes 751 and immersed into the edge of the polyester-cotton knitted elastic fabric to flatten and shape the edge of the polyester-cotton knitted elastic fabric. After being immersed in glue, the edge of the polyester-cotton knitted elastic fabric is quickly dried and shaped by heating column 83, thereby shaping the edge of the polyester-cotton knitted elastic fabric and preventing the edge of the polyester-cotton knitted elastic fabric from rolling inward, which facilitates the subsequent processing of the polyester-cotton knitted elastic fabric.

[0041] When encountering a thicker cotton knitted elastic fabric, the pressure plate 65 rotates, driving the rotating shaft 67 to rotate. Through the torsion spring 69, the pressure plate 65 is forced to rotate towards the side closer to the anti-rolling edge inclined frame 64, limiting the upper surface of the edge of the polyester-cotton knitted elastic fabric, thereby automatically flattening the inward rolled edge of cotton knitted elastic fabric of different thicknesses.

[0042] When the polyester-cotton knitted elastic fabric thickens, the top injection cylinder 75 and the rotating top frame 73 move upward, causing the first clamping seat 761 to move upward in the first slide cylinder 76 and pull the first spring 762. Through the reaction force of the first spring 762, the top injection cylinder 75 is kept close to the bottom injection cylinder 74, so that the polyester-cotton knitted elastic fabric is always clamped between the top injection cylinder 75 and the bottom injection cylinder 74 for stable impregnation. At the same time, the top injection cylinder 75, the rotating top frame 73, the first gear 792, the second auxiliary shaft 791, the second gear 793, and the third sprocket 794 move upward. Through the connection of the transmission chain 783, the first sprocket 781, the first auxiliary shaft 78, and the auxiliary slide 771 move towards the side closer to the rotating bottom frame 72. The second clamping seat 772 slides and pulls the second spring 774. The reaction force of spring 774 causes the auxiliary slide block 771 to always move away from the rotating base frame 72. The first sprocket 781 always pulls the transmission chain 783, so that the transmission chain 783 is always engaged with the outer side of the first sprocket 781, the second sprocket 782 and the third sprocket 794. Thus, by driving the second sprocket 782 to rotate, the first sprocket 781 and the third sprocket 794 are driven to rotate synchronously, which in turn drives the first auxiliary shaft 78 and the second auxiliary shaft 791 to rotate synchronously. Thus, the first gear 792 and the second gear 793 drive the glue injection top cylinder 75 and the glue injection bottom cylinder 74 to rotate synchronously in opposite directions. In turn, the glue injection top cylinder 75 and the glue injection bottom cylinder 74 perform rolling transmission of polyester-cotton knitted elastic fabric, and uniformly impregnate polyester-cotton knitted elastic fabric of different thicknesses with glue.
