Description

Technical Field

[0001] This invention relates to a fabric splicing machine, specifically a low-material-consumption automatic fabric splicing machine that can effectively reduce fabric waste, improve seam flatness, and enhance the efficiency of continuous production line processing. Background Technology

[0002] In continuous production, coating, or subsequent processing of fabrics, when the previous roll of fabric is about to run out, the front end of the new fabric must be joined to the end of the old fabric to maintain the continuous operation of the entire production line.

[0003] However, current technologies mostly use sewing machines to join fabrics. To apply the stitches, the old and new fabrics must overlap, which directly leads to the cutting or waste of overlapping material, resulting in substantial material costs. Furthermore, the overlapping fabric and stitching create noticeable thick bulges at the seams, which can easily cause uneven winding or processing defects during subsequent fabric winding or surface finishing.

[0004] Therefore, how to develop an automatic fabric splicing device that does not require overlapping of fabric, can reliably achieve the goal of low material consumption, and also has a high processing speed is an issue that relevant industries urgently need to solve. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art. The main purpose of this invention is to provide a low-material automatic fabric splicing machine that achieves zero overlap and low material consumption by using a precise fabric end-to-end splicing and segmented pressing design, eliminating the disadvantage of overlapping fabric sewing required in the prior art. Another objective of this invention is to provide a low-material-consumption automatic fabric splicing machine that can reduce embossing and creases in finished fabrics, reduce adhesive waste, and save on waste disposal costs, while also maximizing production speed, ensuring high integrity of the finished products, and producing high-quality finished products with a high yield.

[0006] Another objective of this invention is to provide a low-material-consumption automatic fabric splicing machine that utilizes a segmented pressing structure for end-to-end bonding processing. After the initial pressing in the first stage, the fabric is allowed to move forward, and then the second stage is used for complete pressing and curing. This eliminates the bottleneck of waiting for complete cooling in a single workstation, significantly reduces process waiting time, and thus accelerates production speed.

[0007] Another objective of this invention is to provide a low-material-consumption automatic fabric splicing machine that utilizes a docking platform assembly and a cutting unit located between two pressing assemblies to automatically cut residual adhesive on both sides without interrupting the conveying process, thereby maintaining the precision of the finished product.

[0008] To solve the above-mentioned technical problems, the present invention provides a low-material-consumption automatic fabric splicing machine, comprising: a roll-up assembly for providing two pieces of fabric to be spliced, wherein the fabrics are conveyed forward along a conveying path; an adhesive application assembly disposed on the conveying path for laterally applying a splicing adhesive strip to a joint between the fabrics; a first pressing assembly disposed laterally behind the adhesive application assembly and actuating toward the conveying path for initially pressing the splicing adhesive strip to temporarily fix the spliced ​​fabrics; a second pressing assembly disposed laterally behind the first pressing assembly and actuating toward the conveying path for further pressing the splicing adhesive strip to completely press the spliced ​​fabrics; and a take-up assembly disposed at the end of the conveying path for take-up the spliced ​​fabrics.

[0009] According to an embodiment of the low-material-consumption automatic fabric splicing machine of the present invention, the first pressing component has pre-pressing and heating functions.

[0010] According to an embodiment of the low-material-consumption automatic fabric splicing machine of the present invention, the second pressing component has pressing and heating functions.

[0011] According to one embodiment of the low-material-consumption automatic fabric splicing machine of the present invention, a cutting component is further included below the adhesive application component for cutting the end face of the spliced ​​fabric to form a fabric surface of the same width.

[0012] According to one embodiment of the low-material-consumption automatic fabric splicing machine of the present invention, a docking platform assembly is further included, disposed between the first pressing assembly and the second pressing assembly, for supporting the joined and bonded fabric.

[0013] According to an embodiment of the low-material-consumption automatic fabric splicing machine of the present invention, a cutting unit is provided on the splicing platform assembly for cutting the head and tail waste of the fabric and the residual glue on the side.

[0014] According to one embodiment of the low-material-consumption automatic fabric splicing machine of the present invention, a sensing unit is further included, disposed near the roll-out component, for detecting the fabric rolled out by the roll-out component.

[0015] According to an embodiment of the low-material-consumption automatic fabric splicing machine of the present invention, a cooling component is further provided on one side of the second pressing component, and the cooling component is disposed opposite to the lateral front of the take-up component.

[0016] According to an embodiment of the low-material-consumption automatic fabric splicing machine of the present invention, the adsorption unit is provided on the docking platform assembly, and the adsorption unit of the docking platform assembly adsorbs the pressed fabric.

[0017] The beneficial effects of this invention are as follows: This invention eliminates the material cutting and waste caused by overlapping fabric sewing in existing technologies, achieving zero overlap and low material consumption with high economic efficiency; By segmenting the pressing process, this invention allows the fabric to move forward immediately after the first pressing component completes the initial rapid bonding, completely eliminating the production capacity bottleneck of waiting for the high-temperature hot melt adhesive to cool down at a single workstation in existing technologies, significantly reducing process waiting time and significantly accelerating the continuous processing speed of the entire production line; By cleverly configuring a docking platform component and a fine cutting unit between the two pressing sections, overflowing adhesive strips or side residual adhesive can be thoroughly cleaned and trimmed in real time during the dynamic process of smooth fabric conveying, thereby achieving the effects of ensuring low material consumption, reducing finished fabric embossing and creases, coating adhesive waste, and saving waste disposal costs, while also taking into account the ultimate improvement in production speed, high integrity of the produced products, and high yield of high-quality finished products.

[0024] A low-material-consumption automatic fabric splicing machine is characterized by comprising: a roll-up assembly for providing two pieces of fabric to be spliced, the fabrics being conveyed forward along a conveying path; an adhesive application assembly disposed on the conveying path for laterally applying a splicing adhesive strip to a joint between the fabrics; a first pressing assembly disposed laterally behind the adhesive application assembly and actuating toward the conveying path for initially pressing the splicing adhesive strip to temporarily fix the spliced ​​fabrics; a second pressing assembly disposed laterally behind the first pressing assembly and actuating toward the conveying path for further pressing the splicing adhesive strip to completely press the spliced ​​fabrics; and a take-up assembly disposed at the end of the conveying path for take-up the spliced ​​fabrics.

[0025] The first pressing component has pre-pressing and heating functions.

[0026] The second pressing component has pressing and heating functions.

[0027] It also includes a cutting component located below the adhesive component for cutting the end face of the joined fabric to form a fabric surface of the same width.

[0028] It also includes a docking platform component, disposed between the first pressing component and the second pressing component, for supporting the joined and bonded fabric.

[0029] The docking platform component is equipped with a cutting unit for cutting off the head and tail waste of the fabric and the residual adhesive on the sides.

[0030] It also includes a sensing unit located near the roll-up component to detect the fabric rolled out by the roll-up component.

[0031] A cooling component is further provided on one side of the second pressing component, and the cooling component is disposed in the lateral front of the winding component.

[0032] The docking platform component is equipped with the adsorption unit, which adsorbs the pressed fabric.

[0033] Referring to the accompanying drawings, please first refer to Figures 1 and 2, which are schematic diagrams and implementation diagrams of the low-material-consumption automatic fabric splicing machine of the present invention. The low-material-consumption automatic fabric splicing machine 1 mainly includes a roll-up assembly 10, a sensing unit 101, an adhesive applicator 12, a cutting assembly 13, a first pressing assembly 14, a docking platform assembly 15, a cutting unit 151, a second pressing assembly 16, a cooling assembly 17, and a take-up assembly 18. These components are arranged linearly from front to back along a conveying path for forward conveying of the fabric 2.

[0034] The roll-up assembly 10 is located at the foremost end of the transfer path to release or provide the fabric 2. The sensing unit 101 is located adjacent to the roll-up assembly 10; the sensing unit 101 can be a photoelectric sensing unit to detect the state of the fabric 2 rolled up by the roll-up assembly 10. The adhesive applicator 12 is located on the transfer path, and a cutting assembly 13 is located below the adhesive applicator 12. An adsorption unit 121 is also located below the adhesive applicator 12. The cutting assembly 13 can be a transverse cutter driven by a cylinder. The first pressing assembly 14 is located laterally behind the adhesive applicator 12 and has pre-pressing and heating functions; it can be a pre-pressing plate with a heating element. The docking platform assembly 15 is physically disposed between the first pressing assembly 14 and the second pressing assembly 16 to support the fabric 2. The docking platform assembly 15 is equipped with a cutting unit 151, which can be two opposing longitudinal cutters or a laser cutter. The docking platform assembly 15 also has the adsorption unit 121. The second pressing assembly 16 is disposed laterally behind the docking platform assembly 15 and has pressing and heating functions; it can be a hot press plate with a high-power heater. The cooling assembly 17 is disposed above and below the second pressing assembly 16 on the same device, meaning that the cooling assembly 17 and the second pressing assembly 16 can rotate downwards. The cooling assembly 17 can be a cooling unit with chilled water. The take-up assembly 18 is disposed at the very end of the transfer path and can be a fabric winding shaft mechanism with a drive motor.

[0035] In this low-material-consumption automatic fabric splicing machine 1, when splicing fabric 2, the roll-up component 10 releases the entire roll of fabric 2 to be spliced ​​(such as the end of the previous roll of fabric 2 and the front end of the next roll of fabric 2), and conveys it forward along the transfer path. When the two pieces of fabric 2 stop at the joint position, the cutting component 13 located below the adhesive component 12 moves towards the fabric 2 to cut the end faces of the spliced ​​fabric 2, making the end faces of the two fabric 2 flush to form fabric surfaces of the same width. After being cut and flush, the end faces of the old and new fabric 2 precisely come together on the transfer path to form a non-overlapping joint, and then the adsorption unit 121 adsorbs the end faces of the fabric 2, thus initially restricting and positioning the end faces of the fabric 2. Subsequently, the adhesive assembly 12 located above moves laterally to lay a strip of adhesive across the joint, so that it is laterally bonded between the two fabrics 2. The cutting unit 13 then cuts the ends of the joined fabrics to form fabric surfaces of the same width.

[0036] Next, when the first pressing component 14 moves the fabric 2 with the adhesive strip laid underneath, the first pressing component 14 presses down along the conveying path, using its pre-pressing and heating functions to perform a first-stage rapid bonding, initially pressing the adhesive strip and temporarily fixing the joined fabric 2. The strength of this first-stage initial pressing is sufficient for the production line to pull forward, so after the initial pressing is completed, the first pressing component 14 rises and resets, and the fabric 2 continues to be conveyed forward and carried by the docking platform component 15. When the fully pressed fabric 2 passes through the docking platform component 15, the adsorption unit 121 of the docking platform component 15 maintains the adsorption of the pressed fabric 2, while the cutting unit 151 provided on the docking platform component 15 cuts the sides and ends of the fabric 2 in real time, cutting off residual adhesive or excess adhesive on the sides of the fabric 2, so that the edges of the joined fabric 2 return to a completely flat state. Subsequently, the fabric 2 enters below the second pressing assembly 16, which presses down along the transfer path, utilizing its pressing and heating functions to perform a second stage of complete compaction and high-temperature pressing, fully pressing the adhesive strip together. After completing the segmented pressing at both ends, the second pressing assembly 16 flips over, so that the cooling assembly 17 faces the fabric. The cooling assembly 17 is cooled by its chilled water, and its cooling function rapidly cools, solidifies, and sets the hot melt adhesive.

[0037] In summary, the low-material-consumption automatic fabric splicing machine 1 of the present invention, through precise fabric-to-fabric splicing and segmented pressing design, successfully eliminates the material cutting and waste caused by the overlapping fabric sewing required in the prior art, achieving zero overlap and low material consumption with high economic efficiency. Furthermore, the secondary objective of the present invention is to segment the pressing process, allowing the fabric 2 to move forward immediately after the first pressing component 14 completes the initial rapid bonding, completely eliminating the production capacity bottleneck of waiting for the high-temperature hot melt adhesive to cool down at a single station in the prior art, and significantly reducing the process time. This invention reduces waiting time and significantly speeds up the continuous processing of the entire production line. Furthermore, another objective of this invention is to cleverly configure a docking platform assembly 15 and a fine cutting unit 151 between the two pressing sections. This allows for the real-time and thorough removal and trimming of overflowing adhesive strips or side residues during the smooth dynamic transport of the fabric 2. This achieves the goal of ensuring low material consumption while reducing embossing and creases in the finished fabric, adhesive waste, and waste disposal costs. It also maximizes production speed while maintaining high integrity and yield of high-quality finished products.

[0038] The present invention has been described in detail above. However, the above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of the present invention should still fall within the patent coverage of the present invention.
