Description

Technical Field

[0001] The present invention relates to the technical field of fabric processing, and in particular to a composite device for TPE composite fabrics and a method for using the same. Background Art

[0002] In the production process of TPE composite fabrics, the composite device is a key equipment. For example, the utility model with announcement number CN212194623U.

[0003] Traditional lamination equipment doesn't preheat the substrate and TPE material sufficiently during the preheating process, making it difficult for the adhesive to fully penetrate the substrate, affecting the lamination process and resulting in low peel strength for the composite film. Furthermore, traditional equipment wastes hot air, as the preheating and drying processes are independent, preventing the hot air from being recycled and increasing energy consumption.

[0004] Cutting and conveying composite fabrics is inconvenient, impacting production efficiency. Furthermore, replacing the take-up roller requires pulling the cut fabric out of the composite unit and attaching it to the take-up roller before rewinding can begin, making installation of the take-up roller cumbersome. Furthermore, during the adhesive coating process, excess adhesive cannot be effectively collected and reused, increasing production costs.

[0005] Therefore, a composite device for TPE composite fabrics that can solve the above problems is needed. Summary of the Invention

[0038] (e) Adhere the end of the fabric conveyed by the guide roller to the new take-up roller and start rewinding;

[0039] S6. Anti-drop assistance: During the fabric conveying in step S5(c), air is blown toward the blade slot to push the passing fabric upwards to prevent its end from falling into the slot.

[0040] Beneficial effect: In the present invention, the two guide rollers rotate below the structural frame, the output shaft of the electric linear push rod II is fixedly connected to the cutting blade through a connecting fixed plate, the outer wall of the rotating shaft of one of the guide rollers is sleeved with a one-way rotating bearing, the outer ring of the one-way rotating bearing is fixed with a transmission gear I, and the bottom of the connecting fixed plate is fixed with a toothed bar; the electric linear push rod II drives the cutting blade to move downward to complete the cutting of the composite fabric, the output shaft of the electric linear push rod II pushes the connecting fixed plate and the cutting blade to move upward, the connecting fixed plate drives the toothed bar to move upward synchronously, the toothed bar drives the guide roller to rotate unidirectionally through the transmission gear I and the one-way rotating bearing, and the composite fabric is conveyed in the direction of the winding roller, so that when the winding roller is replaced later, the composite fabric can be re-wound on the replaced winding roller;

[0041] In the present invention, a blade embedding groove that matches the cutting blade is provided on the top of the cutting workbench, and a plurality of air blowing pipes are fixed on the top of the fluid return pipe, and the top ends of the plurality of air blowing pipes are fixedly extended into the blade embedding groove, and are used to blow the fabric upward during the fabric conveying process of the guide roller in the direction of the hot air drying box after the cutting blade completes cutting the composite fabric; after the cutting blade completes cutting, the guide roller conveys the fabric in the direction of the winding roller, and the air blown out of the air blowing pipe can push the fabric upward when the fabric passes through the blade embedding groove, preventing one end of the fabric from falling into the blade embedding groove, thereby ensuring that the fabric is smoothly conveyed to the direction of the winding roller, making it convenient for the winding roller to be wound again after being replaced later, thereby improving the winding efficiency;

A ventilation duct is fixed to the bottom of the hot air drying box, and ventilation ducts I are fixed on both sides of the ventilation duct. The two ventilation ducts I are rotatably connected to one end of the two preheating guide rollers respectively. After the hot air in the hot air drying box dries the composite fabric, it is guided into the two preheating guide rollers through the ventilation duct and the ventilation duct I. The hot air in the preheating guide rollers is blown toward the substrate and TPE raw material through the exhaust holes and the shielding protective cover, so that the hot air can fully preheat the substrate and TPE raw material, promote the subsequent penetration of adhesive molecules into the capillary pores of the substrate, enhance the initial adhesion, and thus improve the peeling strength of the composite film, which not only greatly improves the utilization rate of the hot air but also facilitates the subsequent extrusion and composite of the substrate and TPE raw material.

[0044] In the present invention, the preheating structure allows hot air to fully preheat the substrate and TPE raw materials, promotes the penetration of the adhesive, enhances the initial adhesion, improves the peeling strength of the composite film, and also improves the utilization rate of the hot air.

[0058] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application.

[0059] In an embodiment, referring to Figure 1 and Figure 2 , the composite device relates to the technical field of fabric processing and mainly comprises a working base 1, and an assembly support 2 is fixed on the top of the working base 1. The assembly support 2 serves as a support structure of the whole device and provides mounting positions for other components.

[0060] Referring to Figure 2-Figure 4 , a pay-off roller I 3 and a pay-off roller II 4 are rotatably connected in the assembly support 2, and the pay-off roller I 3 is located below the pay-off roller II 4. The pay-off roller I 3 is used for paying off a base material, and the pay-off roller II 4 is used for paying off a TPE material. In order to enable the base material and the TPE material to be fully compounded in the later stage, a preheating structure is arranged in the assembly support 2. The preheating structure comprises two shielding protective covers 7 fixed in the assembly support 2, and a preheating guide roller 5 is rotatably connected in each of the two shielding protective covers 7. The two preheating guide rollers 5 are used for guiding the base material and the TPE material in cooperation with the pay-off roller I 3 and the pay-off roller II 4, respectively. The top of each of the two shielding protective covers 7 is provided with an opening, and the top of the preheating guide roller 5 penetrates through the opening. A plurality of air outlet holes 6 (φ1-2mm) are arranged in the preheating guide roller 5. When the preheating guide roller 5 rotates, hot air is blown to the base material and the TPE material through the air outlet holes 6, so as to preheat the base material and the TPE material.

[0061] Specifically, when the base material and the TPE raw material pass through the two preheating guide rollers 5, the hot air in the preheating guide roller 5 is sprayed to the base material and the TPE raw material through the air outlet holes 6 in the rotating process of the preheating guide roller 5. At the same time, the hot air in the preheating guide roller 5 enters the shielding protective cover 7 through the air outlet holes 6 and is blown to the base material and the TPE raw material at the opening of the shielding protective cover 7, so that the hot air can fully preheat the base material and the TPE raw material. This preheating mode can promote the penetration of the adhesive molecules into the capillary pores of the base material in the later stage, enhance the initial adhesion, and thus improve the peeling strength of the composite film.

[0062] Referring to Figure 2 and Figure 5The composite device also includes an adhesive coating structure, which includes a glue roller 9 and a scraper plate 13 that evenly coats the adhesive on the substrate. Specifically, the coating structure also includes a glue storage tank 8 fixed in the assembly bracket 2. The bottom of the glue storage tank 8 is rotatably connected to the glue roller 9 via a base, and the top of the glue roller 9 extends into the glue storage tank 8. When the glue roller 9 rotates, the adhesive in the glue storage tank 8 adheres to the outer wall of the glue roller 9, causing the glue roller 9 to coat the adhesive on the surface of the substrate. The bottom of the glue storage tank 8 is rotatably connected to a positioning and limiting roller 10 via a base, and the glue roller 9 is located above the positioning and limiting roller 10, and the substrate passes through the gap between the glue roller 9 and the positioning and limiting roller 10. When the glue roller 9 applies the adhesive, the positioning and limiting roller 10 supports the bottom of the substrate to ensure the stability of the coating process.

[0063] Reference Figure 2 and Figure 6 A U-shaped support plate 11 is fixed in the assembly bracket 2, and a scraper plate 13 is fixed to the top inner wall of the U-shaped support plate 11. The inner walls of the U-shaped support plate 11 on both sides away from each other are provided with guide grooves 12. The two ends of the scraper plate 13 extend into the corresponding guide grooves 12 to guide the adhesive on the scraper plate 13 into the guide grooves 12. A fluid guide rod 14 is fixed to the inner wall of one side of the two guide grooves 12. A glue collection box 15 is fixed in the assembly bracket 2 below the U-shaped support plate 11. The top of the glue collection box 15 is provided with two through holes 16. The bottom ends of the two fluid guide rods 14 pass through the through holes 16 and extend into the glue collection box 15.

[0064] As the substrate passes through the glue roller 9 and the positioning and limiting rollers 10, the motor drives the glue roller 9 to rotate. During this rotation, the glue roller 9 draws the adhesive from the glue storage tank 8 and applies it to the substrate. The glue roller 9 and the positioning and limiting rollers 10 work together to support the substrate's coated surface, ensuring uniform coating. Furthermore, the scraper plate 13 evenly applies the adhesive to the substrate's surface. Excess adhesive flows to the sides of the scraper plate 13 and, guided by the guide channels 12 and fluid guide rods 14, is discharged into the glue collection tank 15, where it is collected and reused later.

[0065] Reference Figure 2 and Figure 6The device also includes a composite roller I 17 that rotates within an assembly bracket 2. A transverse support plate 18 is secured within the assembly bracket 2, and an electric linear actuator I 19 is secured to the bottom of the transverse support plate 18. A U-shaped mounting bracket 20 is secured to the output shaft of the electric linear actuator I 19. The U-shaped mounting bracket 20 slides within the assembly bracket 2. A composite roller II 21, which mates with composite roller I 17, is rotatably connected within the U-shaped mounting bracket 20. The electric linear actuator I 19 controls the raising and lowering of composite roller II 21, enabling composite roller I 17 and composite roller II 21 to extrude and laminate the substrate and TPE material.

[0066] During the lamination process, electric linear actuator I 19 activates, pushing the U-shaped mounting frame 20 and laminating roller II 21 downward, bringing laminating roller II 21 closer to laminating roller I 17. This squeezes the substrate and TPE material passing between them, achieving lamination. By controlling the stroke of electric linear actuator I 19, the height of laminating roller II 21 can be adjusted to accommodate substrates and TPE materials of varying thickness and laminating requirements.

[0067] Reference Figure 2 and Figure 9 The composite device also includes a cutting and conveying structure for cutting the composite fabric and conveying it to one side. The cutting and conveying structure includes a cutting table 27 fixed to the assembly bracket 2. A cutting blade 30 and two guide rollers 29 are provided above the cutting table 27 for cutting and conveying the composite fabric.

[0068] Reference Figure 2 、 Figure 9 and Figure 10 Specifically, the cutting and conveying structure also includes a structural frame 28 fixed within the assembly bracket 2 and positioned above the cutting table 27. Two guide rollers 29 are both rotated below the structural frame 28 via a base. The guide rollers 29 cooperate with the cutting table 27 to convey the composite fabric as they rotate. The two guide rollers 29 are connected via a synchronous pulley and a synchronous belt transmission to ensure synchronous rotation of the two guide rollers 29. An electric linear actuator II 32 is fixed to the top of the structural frame 28. The output shaft of the electric linear actuator II 32 is fixed to a connecting plate 31. The connecting plate 31 is fixedly connected to one side of a cutting blade 30. The cutting blade 30 slides within the assembly bracket 2, and the bottom end of the cutting blade 30 slides through the structural frame 28 to complete the cutting of the composite fabric.

[0069] Reference Figure 10 and Figure 11A one-way rotating bearing 34 is mounted on the outer wall of the rotating shaft of one of the guide rollers 29. The inner ring of the one-way rotating bearing 34 is fixed to the outer wall of the rotating shaft of one of the guide rollers 29. A transmission gear I 35 is fixed to the outer ring of the one-way rotating bearing 34. A toothed bar 33 is fixed to the bottom of the connecting plate 31 and meshes with the transmission gear I 35. When the electric linear actuator II 32 drives the cutting blade 30 upward, it drives the guide roller 29 to rotate counterclockwise, conveying the cut products. A blade slot 36 is provided on the top of the cutting table 27, which mates with the cutting blade 30 and makes way for the cutting blade 30 when it moves downward for cutting.

[0070] During operation, the electric linear actuator II 32 drives the connecting plate 31 downward, which in turn drives the cutting blade 30 downward into the blade slot 36, completing the cutting of the composite material. The output shaft of the electric linear actuator II 32 then pushes the connecting plate 31 and the cutting blade 30 upward, disengaging the cutting blade 30 from the blade slot 36. The connecting plate 31 simultaneously drives the toothed bar 33 upward, which in turn rotates the transmission gear I 35. Driven by the one-way rotating bearing 34, the transmission gear I 35 drives the guide roller 29 in unidirectional rotation. The two guide rollers 29 are connected by a synchronous pulley and a synchronous belt. They rotate synchronously, conveying the composite material toward the take-up roller 37. This facilitates rewinding of the composite material onto the new take-up roller 37 when the take-up roller 37 is later replaced.

[0071] Reference Figure 1 、 Figure 2 and Figure 12A winding roller 37 is provided in the assembly bracket 2 for winding up the composite fabric. In order to facilitate the rapid replacement of the winding roller 37 at a later stage, a replacement structure is provided in the assembly bracket 2, and the cutting and conveying structures are used to control the replacement structure. The replacement structure includes two U-shaped positioning and limiting plates 38 fixed to the inner walls of the assembly bracket 2 on both sides away from each other. The rotating shafts at both ends of the winding roller 37 extend into the corresponding U-shaped positioning and limiting plates 38 respectively. Blocking baffles 39 for limiting the rotating shaft of the winding roller 37 slide in the two U-shaped positioning and limiting plates 38. The top ends of the two blocking baffles 39 slide and extend above the U-shaped positioning and limiting plates 38. The top ends of the two blocking baffles 39 are fixed with vertical rods 40. Two traction and pulling plates 41 are fixed to one side of the cutting blade 30. The top ends of the two vertical rods 40 slide through the corresponding traction and pulling plates 41 and are fixed with fixed discs 43. The outer walls of the two vertical rods 40 are sleeved with elastic springs 42. The spring constant of the elastic spring 42 ranges from 50 N / m to 200 N / m, and the initial compression ranges from 10 mm to 30 mm. The top and bottom ends of the elastic spring 42 are fixedly connected to the bottom of the fixed disk 43 and the top of the traction plate 41, respectively, via spring seats. This allows the elastic spring 42 to drive the blocking plate 39 downward to limit the rotation axis of the winding roller 37 when the traction plate 41 moves downward. When the traction plate 41 moves upward, the elastic spring 42 drives the blocking plate 39 upward to release the limit on the rotation axis of the winding roller 37.

[0072] When the cutting blade 30 moves upward, the pulling plate 41 drives the vertical rod 40 and the blocking baffle 39 upward, and the blocking baffle 39 releases the obstruction on the rotating shaft of the winding roller 37, allowing the rotating shaft of the winding roller 37 to be removed from the two U-shaped positioning and limiting plates 38, thus completing the removal of the winding roller 37. Conversely, the rotating shaft of the new winding roller 37 is replaced in the two U-shaped positioning and limiting plates 38, and the electric linear actuator II 32 drives the pulling plate 41 and the blocking baffle 39 downward by connecting to the fixed plate 31, re-blocking the rotating shaft of the winding roller 37, thereby completing the installation of the winding roller 37.

[0073] Reference Figure 2 、 Figure 3 and Figure 8A hot air drying box 22 is fixed in the assembly bracket 2. The hot air drying box 22 is located between the composite roller Ⅰ 17 and the cutting table 27, and the composite fabric passes through the hot air drying box 22. A plurality of electric heating plates 23 are fixed to the top inner wall of the hot air drying box 22, which are used to heat the air in the hot air drying box 22. A plurality of air blowers 24 are fixed to the top of the hot air drying box 22. The air outlet ends of the air blowers 24 extend into the hot air drying box 22 to blow hot air to the composite fabric. A ventilation duct 25 is fixed to the bottom of the hot air drying box 22. Ventilation ducts Ⅰ 26 are fixed on both sides of the ventilation duct 25. The two ventilation ducts Ⅰ 26 are respectively connected to one end of the two preheating guide rollers 5 for rotating and injecting hot air into the preheating guide rollers 5 to preheat the substrate and TPE material.

[0074] The composite material enters the hot air drying box 22, where the hot air heated by the electric heating plate 23 is blown toward the composite material by the air blower 24, completing the drying process. The hot air in the hot air drying box 22 is then guided through the ventilation duct 25 and the ventilation conduit I 26 to the two preheating guide rollers 5, where it preheats the substrate and TPE material to be laminated. This not only greatly improves the utilization rate of the hot air but also facilitates the subsequent extrusion and lamination of the substrate and TPE material.

[0075] Reference Figure 12 The inner wall of one side of the assembly bracket 2 is rotatably connected to a transmission gear III 45, and a transmission gear II 44 is fixedly sleeved on the outer wall of the rotating shaft at one end of the winding roller 37. The transmission gear II 44 is engaged with the transmission gear III 45. After the installation of the winding roller 37 is completed, the transmission gear III 45 and the transmission gear II 44 are cooperated to drive the winding roller 37 to rotate to complete the winding operation.

[0076] In another embodiment: Figure 2 、 Figure 9 and Figure 11 This embodiment is an improvement on Example 1: a fluid return pipe 47 is fixed within the assembly bracket 2 and is located below the cutting table 27. A ventilation duct II 46 is fixed to one side of the ventilation duct 25 and is connected to the fluid return pipe 47. This duct is used to inject hot air from the hot air drying oven 22 into the fluid return pipe 47. Multiple airflow pipes 48 are fixed to the top of the fluid return pipe 47. The top ends of the multiple airflow pipes 48 extend into the blade slot 36 to blow the fabric upward.

[0077] After the cutting blade 30 completes cutting, the guide roller 29 transports the fabric toward the winding roller 37. The air blown out by the air blowing pipe 48 can push the fabric upward when the fabric passes through the blade groove 36, preventing one end of the fabric from falling into the blade groove 36, thereby ensuring that the fabric is smoothly transported to the direction of the winding roller 37, making it convenient for the winding roller 37 to be replaced later to perform the winding operation again, thereby improving the winding efficiency.

[0078] A method for using a composite device for a TPE composite fabric comprises the following steps:

[0079] S1. The substrate and TPE raw material to be compounded are respectively unwound by unwinding roller I3 and unwinding roller II4. The substrate and TPE raw material are preheated at the preheating guide roller 5. The substrate is coated with adhesive when passing under the glue storage box 8. Then the substrate and TPE raw material enter between compounding roller I17 and compounding roller II21 to complete the extrusion compounding. The compounded fabric enters the hot air drying box 22 for drying and is then wound on the winding roller 37.

[0080] S2. When the substrate and the TPE raw material pass through the two preheating guide rollers 5, they can be preheated to facilitate the subsequent coating of the adhesive and extrusion composite. When the preheating guide rollers 5 rotate, the hot air inside them is sprayed toward the substrate and the TPE raw material through the exhaust port 6. In addition, the hot air in the preheating guide rollers 5 enters the shielding protective cover 7 through the exhaust port 6 and is blown toward the substrate and the TPE raw material at the opening of the shielding protective cover 7, so that the hot air can fully preheat the substrate and the TPE raw material, promote the subsequent penetration of the adhesive molecules into the capillary pores of the substrate, enhance the initial adhesion, and thus improve the peel strength of the composite film;

[0081] S3. When the substrate passes through the glue roller 9 and the positioning and limiting roller 10, the glue roller 9 is driven by the motor to rotate. During the rotation of the glue roller 9, the adhesive in the glue storage box 8 is brought out and coated on the substrate. The cooperation between the glue roller 9 and the positioning and limiting roller 10 can support the coating surface of the substrate. In addition, the scraping plate 13 can evenly apply the adhesive on the surface of the substrate, and the excess adhesive flows to the two sides of the scraping plate 13 and is guided and discharged into the glue collection box 15 under the action of the guide groove 12 and the fluid guide rod 14. It is collected and convenient for later reuse;

[0082] S4. When the adhesive-coated substrate and the TPE raw material pass between the composite roller I 17 and the composite roller II 21, the pressure applied by the electric linear push rod I 19 to the composite roller II 21 can cause the substrate and the TPE raw material to be extruded and composited to form a composite fabric. When the composite roller I 17 and the composite roller II 21 are extruded and composited, the temperature of both is maintained at 80°C-100°C. Then the composite fabric enters the hot air drying box 22, and the hot air heated by the electric heating plate 23 is blown to the composite fabric by the air flow blower 24 to complete the drying operation. The hot air in the hot air drying box 22 is guided to the two preheating guide rollers 5 through the ventilation duct 25 and the ventilation duct I 26 to preheat the substrate and TPE raw material to be composited, which not only greatly improves the utilization rate of the hot air but also facilitates the extrusion and composite of the substrate and the TPE raw material in the later stage.

[0083] S5, the motor drives the transmission gear III 45 to rotate, and the transmission gear III 45 cooperates with the transmission gear II 44 to drive the winding roller 37 to rotate to complete the winding of the composite fabric. When the winding roller 37 is wound up, the electric linear push rod II 32 drives the connecting fixed plate 31 to move down, and the connecting fixed plate 31 drives the cutting blade 30 to move down and move into the blade embedding groove 36 to complete the cutting of the composite fabric. Then the output shaft of the electric linear push rod II 32 pushes the connecting fixed plate 31 and the cutting blade 30 to move up, and the cutting blade 30 moves from The blade is disengaged from the groove 36, and the connecting fixed plate 31 drives the toothed bar 33 to move upward synchronously. The toothed bar 33 drives the transmission gear I 35 to rotate. The transmission gear I 35 drives the guide roller 29 to rotate unidirectionally under the action of the one-way rotating bearing 34. The two guide rollers 29 are connected by a synchronous wheel and a synchronous belt. The two guide rollers 29 rotate synchronously to convey the composite fabric toward the winding roller 37, so that when the winding roller 37 is replaced later, the composite fabric can be rewound on the replaced winding roller 37.

[0084] When the cutting blade 30 moves upward, the vertical rod 40 and the blocking baffle 39 are moved upward by the traction plate 41, and the blocking baffle 39 releases the obstruction to the rotating shaft of the winding roller 37, so that the rotating shaft of the winding roller 37 can be taken out from the two U-shaped positioning limit plates 38, and the disassembly of the winding roller 37 is completed. Conversely, the rotating shaft of the new winding roller 37 is replaced in the two U-shaped positioning limit plates 38, and the electric linear push rod II 32 drives the traction plate 41 and the blocking baffle 39 to move downward by the connecting fixed plate 31, and blocks the rotating shaft of the winding roller 37 again, thereby completing the installation of the winding roller 37, and controlling the meshing of the transmission gear II 44 and the transmission gear III 45 during the installation process to avoid tooth collision between the two. Afterwards, the fabric conveyed by the guide roller 29 in step S5 is adhered to the winding roller 37, and the composite fabric is rewound.

[0085] S7. After the cutting blade 30 completes cutting, the guide roller 29 transports the fabric toward the winding roller 37. The air blown out by the air blowing pipe 48 can push the fabric upward when the fabric passes through the blade groove 36, preventing one end of the fabric from falling into the blade groove 36, thereby ensuring that the fabric is smoothly transported to the direction of the winding roller 37, making it convenient for the winding roller 37 to be replaced later to perform the winding operation again, thereby improving the winding efficiency.
