Description

Technical Field

[0001] This utility model relates to the technical field of composite fabric preparation, and in particular to a hot melt bonding machine for the development and preparation of PVC composite fabric. Background Technology

[0002] PVC composite fabrics are a new type of fabric made by combining PVC materials with textiles, non-woven fabrics, or other functional materials through coating, lamination, or pressing processes. Hot melt adhesives are required for bonding during the processing and preparation.

[0003] Currently, when processing PVC composite fabrics, the fabric needs to be conveyed through a transmission component to facilitate winding and movement. However, this makes it difficult to adjust the tension of the fabric, which can easily cause the fabric to loosen or tear. To address this issue, this invention proposes a hot melt bonding machine for the development and preparation of PVC composite fabrics, which differs from existing technologies. Utility Model Content

[0004] To address the aforementioned problem of difficulty in adjusting fabric tension, which can easily lead to fabric loosening or tearing, this invention provides a hot melt bonding machine for the development and preparation of PVC composite fabrics.

[0005] This utility model provides a hot melt bonding machine for the development and preparation of PVC composite fabrics, adopting the following technical solution:

[0006] A hot melt bonding machine for developing and preparing PVC composite fabrics includes a second horizontal plate. Second conversion frames are symmetrically welded to both sides of the upper surface of the second horizontal plate. A bonding frame is installed at one end of the upper surface of the second horizontal plate. A vertical frame is installed at the rear side of the upper surface of the second horizontal plate. Multiple sets of first conversion frames are evenly installed on one side of the upper surface of the vertical frame. A third conversion frame is installed on the other side of the upper surface of the vertical frame. An adhesive injection assembly is installed on the vertical frame. An upper tension adjustment assembly is installed on one side of the top surface of the vertical frame. A lower tension adjustment assembly is installed on one side of the top surface of the second horizontal plate.

[0007] By adopting the above technical solution, the fabrics to be bonded are respectively wound around the second conversion frame, the first conversion frame, and the third conversion frame, and their ends are fixed to the existing winding equipment. The existing winding equipment is used to pull the fabric to move. During the movement of the fabric, the existing hot melt adhesive injection equipment is used to flow the molten hot melt adhesive onto the fabric. Under the action of the third conversion frame, the two sets of fabrics can be bonded with hot melt adhesive. The tension of the fabric is adjusted by screwing on the upper tension adjustment component and the lower tension adjustment component, so as to avoid the fabric from accidentally loosening or tearing.

[0008] Optionally, the glue injection assembly includes a first glue tube, which is fixed on the front side wall of the vertical frame. Multiple sets of glue injection nozzles are evenly connected to the bottom wall of the first glue tube. A second glue tube is installed on the back side wall of the first glue tube, penetrating the vertical frame and communicating with existing hot melt glue injection molding equipment.

[0009] By adopting the above technical solution, the molten hot melt adhesive is injected into the inner cavity of the first adhesive tube through the second adhesive tube. Opening the control valve on the injection nozzle at an appropriate position allows the molten hot melt adhesive to flow onto the fabric.

[0010] Optionally, the upper tensioning adjustment assembly includes a second threaded tube, which is fixedly embedded in the top surface of the vertical frame. A second threaded vertical rod is threaded through the inner thread of the second threaded tube, and a tensioning plate is rotatably connected to the bottom end of the second threaded vertical rod via a bearing.

[0011] Optionally, the lower tension adjustment assembly includes a U-shaped frame positioned above the second horizontal plate. An upper tension roller is installed on the upper surface of the inner cavity of the U-shaped frame. A first threaded vertical rod is rotatably connected to the bottom end of the U-shaped frame via a bearing. A first threaded tube is threadedly sleeved on the outside of the first threaded vertical rod. A first horizontal plate is fixedly sleeved on the outside of the first threaded tube. Both ends of the first horizontal plate are equipped with limiting members that are fixed to the upper surface of the second horizontal plate.

[0012] By adopting the above technical solution, the first threaded vertical rod and the second threaded vertical rod are screwed on, so that the first threaded vertical rod and the second threaded vertical rod can move up and down during rotation under the action of the first threaded tube and the second threaded tube respectively. Under the action of the first threaded vertical rod and the second threaded vertical rod, the return frame, the upper tensioning roller and the tensioning plate can be moved up and down, thereby adjusting the tension of the fabric.

[0013] Optionally, the limiting component includes a vertical slide rod, which is fixed at the end of the outer wall of the first horizontal plate, and a vertical slide tube that is fixed to the bottom of the outer wall of the U-shaped frame is movably sleeved on the outside of the vertical slide rod.

[0014] By adopting the above technical solution, when the loop frame moves up and down, it can drive the vertical slide tube to slide synchronously on the outer wall of the vertical slide rod. Thus, under the action of multiple sets of vertical slide tubes and vertical slide rods, the movement path of the upper tensioning roller and the loop frame can be effectively restricted.

[0015] Optionally, a magnetic strip is fixedly embedded in the middle of the upper surface of the adhesive frame, and an iron pressure strip is provided on the upper surface of the adhesive frame to magnetically attract the magnetic strip. Adhesive recycling frames are provided on both the front and rear sides of the adhesive frame.

[0016] By adopting the above technical solution, the iron pressure strip is placed directly above the magnetic strip and they attract each other using magnetism, thereby automatically spreading the hot melt adhesive on the fabric.

[0017] In summary, this utility model has at least one of the following beneficial effects:

[0018] Tightening the first and second threaded vertical rods can move the return frame, the upper tensioning roller and the tensioning plate up and down, thereby adjusting the tension of the fabric and minimizing the risk of the fabric accidentally loosening or tearing.

[0019] When the spiral frame moves up and down, it can drive the vertical slide tube to slide synchronously on the outer wall of the vertical slide rod. Thus, under the action of multiple sets of vertical slide tubes and vertical slide rods, the movement path of the upper tensioning roller and the spiral frame can be effectively restricted.

[0024] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0025] Please refer to the attached diagram in the instruction manual. Figure 1 and 2An embodiment of this utility model provides a hot melt bonding machine for the development and preparation of PVC composite fabrics, including a second horizontal plate 11. Second conversion frames 12 are symmetrically welded to both sides of the upper surface of the second horizontal plate 11. A bonding frame 10 is installed at one end of the upper surface of the second horizontal plate 11, positioned between the two sets of second conversion frames 12. The upper surface of the bonding frame 10 is on the same horizontal plane as the upper surface of the second conversion frames 12. A vertical frame 14 is installed on the rear side of the upper surface of the second horizontal plate 11. The lateral longitudinal section of the vertical frame 14 is L-shaped. Multiple sets of first conversion frames 1 are evenly installed on one side of the upper surface of the vertical frame 14. A third conversion frame 13 is installed on the other side of the upper surface of the vertical frame 14, positioned directly above the bonding frame 10.

[0026] Please refer to the attached diagram in the instruction manual. Figure 1 and 2 A glue injection assembly is installed on the vertical frame 14. The glue injection assembly includes a first glue tube 17, which is fixed on the front side wall of the vertical frame 14. Multiple glue injection nozzles 16 are evenly connected to the bottom wall of the first glue tube 17. A second glue tube 19 is installed on the back side wall of the first glue tube 17, which penetrates the vertical frame 14 and is connected to the existing hot melt glue injection equipment. The hot melt glue injection equipment includes, but is not limited to, a hot melt glue storage tank. The first glue tube 17 and the glue injection nozzles 16 are both located between the first conversion frame 1 and the third conversion frame 13. A control valve is installed on the outside of the second glue tube 19.

[0027] The fabrics to be bonded are respectively wound around the second conversion frame 12, the first conversion frame 1, and the third conversion frame 13, and their ends are fixed to the existing winding equipment. The existing winding equipment is used to pull the fabric to move. During the movement of the fabric, the second glue tube 19, the first glue tube 17 and the glue injection nozzle 16 can be used to make the molten hot melt adhesive flow onto the fabric. Under the action of the third conversion frame 13, the two sets of fabrics can be bonded with hot melt adhesive.

[0028] Please refer to the attached diagram in the instruction manual. Figure 1 and 2 A tension adjustment assembly is installed on one side of the top surface of the vertical frame 14. The tension adjustment assembly includes a second threaded tube 21, which is fixedly embedded in the top surface of the vertical frame 14. A second threaded vertical rod 20 is threaded through the inner thread of the second threaded tube 21. A lever is installed at the upper end of the second threaded vertical rod 20. A tensioning plate 18 is rotatably connected to the bottom end of the second threaded vertical rod 20 through a bearing. The tensioning plate 18 is positioned between the two sets of first conversion frames 1.

[0029] Please refer to the attached diagram in the instruction manual. Figure 1 , 23. A lower tension adjustment assembly is installed on one side of the top surface of the second horizontal plate 11. The lower tension adjustment assembly includes a U-shaped frame 22, which is located above the second horizontal plate 11 and between the second conversion frame 12 and the adhesive frame 10. The U-shaped frame 22 is located directly below the tension plate 18. An upper tension roller 2 is installed on the upper surface of the inner cavity of the U-shaped frame 22. A first threaded vertical rod 6 is rotatably connected to the bottom end of the U-shaped frame 22 through a bearing. A turning rod is installed on the lower end face of the first threaded vertical rod 6. A first threaded tube 5 is threadedly sleeved on the outside of the first threaded vertical rod 6. A first horizontal plate 7 is fixedly sleeved on the outside of the first threaded tube 5.

[0030] Tightening the first threaded vertical rod 6 and the second threaded vertical rod 20 allows the first threaded vertical rod 6 and the second threaded vertical rod 20 to move up and down during rotation under the action of the first threaded tube 5 and the second threaded tube 21, respectively. Under the action of the first threaded vertical rod 6 and the second threaded vertical rod 20, the spiral frame 22, the upper tensioning roller 2 and the tensioning plate 18 can be moved up and down, thereby adjusting the tension of the fabric.

[0031] Please refer to the attached diagram in the instruction manual. Figure 1 and 3 Both ends of the first horizontal plate 7 are equipped with limiting components that are fixed to the upper surface of the second horizontal plate 11. The limiting components include vertical slide rods 4, which are fixed to the outer end of the first horizontal plate 7. A vertical slide tube 3, which is fixed to the bottom of the outer wall of the U-shaped frame 22, is movably sleeved on the outside of the vertical slide rod 4. When the U-shaped frame 22 moves up and down, it can drive the vertical slide tube 3 to slide synchronously on the outer wall of the vertical slide rod 4. Thus, under the action of multiple sets of vertical slide tubes 3 and vertical slide rods 4, the movement path of the upper tension roller 2 and the U-shaped frame 22 can be effectively restricted.

[0032] Please refer to the attached diagram in the instruction manual. Figure 1 and 2 A magnet strip 9 is fixedly embedded in the middle of the upper surface of the adhesive frame 10. An iron pressure strip 15 is provided on the upper surface of the adhesive frame 10, which magnetically attracts the magnet strip 9. The lateral length of the iron pressure strip 15 is greater than the lateral length of the adhesive frame 10. Adhesive recycling frames 8 are provided on both the front and rear sides of the adhesive frame 10. The upper surface of the adhesive recycling frame 8 is open.

[0033] The iron pressure strip 15 is placed directly above the magnetic strip 9 and they attract each other using magnetism, which can automatically scrape the hot melt adhesive on the fabric evenly. Excess hot melt adhesive can automatically drip down through the outer edge of the adhesive frame 10 and be collected in the inner cavity of the adhesive recycling box 8, thus minimizing the waste of hot melt adhesive.

[0034] Working principle: When using this PVC composite fabric to develop a hot melt adhesive bonding machine, the fabric to be bonded is wound around the second conversion frame 12, the first conversion frame 1, and the third conversion frame 13 respectively, and its ends are fixed to the existing winding equipment. The existing winding equipment pulls the fabric to move. During the movement of the fabric, the existing hot melt adhesive injection equipment injects the molten hot melt adhesive into the inner cavity of the first adhesive tube 17 through the second adhesive tube 19. Opening the control valve on the injection nozzle 16 at an appropriate position allows the molten hot melt adhesive to flow onto the fabric. The iron pressure strip 15 is placed directly above the magnetic strip 9 and they are attracted to each other by magnetism, thereby automatically scraping the hot melt adhesive evenly on the fabric.

[0035] Under the action of the third conversion frame 13, the two sets of fabrics can be bonded with hot melt adhesive. Excess hot melt adhesive can automatically drip from the outer edge of the bonding frame 10 and be collected in the inner cavity of the adhesive recycling frame 8, so as to avoid waste of hot melt adhesive. Twisting the first threaded vertical rod 6 and the second threaded vertical rod 20 can make the first threaded vertical rod 6 and the second threaded vertical rod 20 move up and down during rotation under the action of the first threaded tube 5 and the second threaded tube 21, respectively. Under the action of the first threaded vertical rod 6 and the second threaded vertical rod 20, the return frame 22, the upper tensioning roller 2 and the tensioning plate 18 can be moved up and down, thereby adjusting the tension of the fabric and avoiding accidental loosening or tearing of the fabric.

[0036] When the loop frame 22 moves up and down, it can drive the vertical slide tube 3 to slide synchronously on the outer wall of the vertical slide rod 4. Thus, under the action of multiple sets of vertical slide tubes 3 and vertical slide rods 4, the movement path of the upper tension roller 2 and the loop frame 22 can be effectively restricted.
