Description

Technical Field

[0001] This invention discloses a coating device for adhesive interlining coated fabrics, relating to the field of interlining coating application technology. Background Technology

[0002] Interlining is a special garment accessory made of woven, knitted, or nonwoven fabrics as the base material, using thermoplastic polymer compounds and undergoing special finishing processes by specialized machinery. It is used as the inner layer of clothing to provide reinforcement and stiffness, and is bonded to the fabric. Interlining can act as a skeleton and support in work clothes and is generally used in suits, overcoats, and formal wear. Interlining coating refers to coating the surface of the interlining with a special substance to enhance its performance and function.

[0003] In some small lining production workshops, the coating of the base fabric is usually applied manually. First, hot melt adhesive is poured onto the fabric, and then a scraper is used to spread the hot melt adhesive evenly on the base fabric. After it cools and solidifies, the coating is complete. For large lining factories, the inclined plate method is currently more commonly used for coating. Hot melt adhesive is placed in a funnel and falls from the slot onto an inclined vibrating slide plate. Then, it slides onto the base fabric and is simultaneously conveyed through rollers, which use the rollers to spread the hot melt adhesive evenly. However, when using this method to apply the coating, the hot melt adhesive flows downward through the vibration of the slide plate, and the vibration is unstable. This can lead to differences in the amount of hot melt adhesive falling onto the base fabric within the same time interval, which can easily result in uneven coating thickness in the produced lining. Summary of the Invention

[0004] In order to solve the technical problems existing in the prior art, a coating device for adhesive interlining coated fabric is provided.

[0005] The technical solution of this invention is: a coating device for adhesive interlining coated fabric, comprising a support base, a conveying module for conveying the base fabric, and a coating mechanism for applying a coating to the base fabric; the top of the support base is provided with a conveying table that fits against the outlet of the conveying module; the coating mechanism includes a triangular box capable of conveying the base fabric on the conveying table outward and providing space for coating the base fabric; a fluid glue tank for storing the hot melt adhesive required for coating; and an adhesive application assembly for coating the base fabric; the adhesive application assembly includes a component capable of rotating synchronously with the rotating shaft of the triangular box via gear transmission. The system comprises: a rotating glue-applying roller; a folded tube disposed on the triangular box and located inside the glue-applying roller; a glue-feeding pipe for connecting the fluid glue tank and the folded tube; and a glue-applying roller for evenly grinding the hot melt glue; a valve is provided on the glue-feeding pipe; the folded tube is divided into two parts: a round tube and an L-shaped tube, with the horizontal opening of the L-shaped tube connected to the round tube and located in the middle of the round tube; the bottom opening of the L-shaped tube part of the folded tube is oblique and contacts the glue-applying roller part; the glue-applying roller is a hollow barrel with multiple openings of the same diameter on its outer wall, and the openings are neatly arranged on the outer wall of the glue-applying roller.

[0006] Furthermore, the coating mechanism also includes a scraper; the scraper is hook-shaped, and its hook is arc-shaped and fits against the left inner oblique side wall of the triangular box, which can flatten the base fabric; the scraper is positioned slightly higher than the coating roller, and the base fabric after being flattened by the scraper will be immediately sent to the coating roller for coating application.

[0007] Furthermore, a spreading mechanism is provided on the conveyor table. The spreading mechanism consists of a powder storage component, a powder sieving component, a powder dropping component, and a vibration component. The spreading mechanism can spread powdered hot melt adhesive onto the base fabric before applying the coating, making the coating on the lining thicker and improving its overall performance.

[0008] Furthermore, the powder storage assembly includes a powdered glue box for storing powdered hot melt adhesive; and a conveying channel for conveying the powdered hot melt adhesive in the powdered glue box; the conveying channel is provided at both outlets of the powdered glue box, which can realize bidirectional conveying of the powdered hot melt adhesive.

[0009] Furthermore, the powder sieving assembly includes a cylindrical shell that provides a sealed space for dispersing the powdered hot melt adhesive; a sieve cylinder that can rotate within the cylindrical shell and disperse the powdered hot melt adhesive evenly; a dual-shaft motor that provides power for the rotation of the sieve cylinder; a full gear disposed at the end of the output shaft of the dual-shaft motor and capable of rotating synchronously with the output shaft of the dual-shaft motor; and a gear ring disposed on the sieve cylinder and meshing with the full gear.

[0010] Furthermore, the inner diameter of the screen cylinder gradually increases from its center to both sides, forming an inclined plane with a slope of less than 30° between its inner center and its ends; the diameter of the opening on the screen cylinder gradually increases from its center to both sides; the dual-axis motor is synchronously driven and can simultaneously provide driving force to both ends of the screen cylinder in the same direction.

[0011] Furthermore, the bottom of the powdered glue box is composed of two inclined plates that rise towards the center; the two conveying channels extend from the opening of the powdered glue box to the inside of the screen cylinder near the center, and a certain space is reserved between the outlets of the two conveying channels; the inside of the two conveying channels is sloped along their conveying direction.

[0012] Furthermore, the powder dispensing assembly includes a sieve frame for distributing hot melt powder onto the base fabric; and an air impeller for further dispersing the hot melt powder evenly; the sieve frame is located at the bottom of the cylinder shell, and the distance between it and the conveying platform is between 2cm and 3cm; the air impeller rotates at a speed not exceeding 30 revolutions per second, and can only provide a slight breeze to the sieve frame.

[0013] Furthermore, the shock assembly includes a sleeve disposed at the end of the cylinder shell; a shocker symmetrically installed inside the sleeve to assist in the dispersion of the powder hot melt adhesive inside the sieve cylinder; and a shock ring that provides buffer protection for the sieve cylinder.

[0014] Furthermore, a preheating module capable of heating the base fabric is provided at the conveying shaft of the conveying module. The preheating module consists of a fan and a heater, which are arranged alternately to uniformly preheat the base fabric conveyed to the preheating module.

[0015] The beneficial effects are: 1. The present invention uses the setting of the coating mechanism to transport the hot melt adhesive in the fluid glue tank to the folded tube through the glue delivery pipe. Under the special structure of the folded tube, the hot melt adhesive needs to fill its round tube part first, and then flow evenly into the glue coating roller along the L-shaped rod. Then the glue coating roller rotates and cooperates with the glue coating roller to make the hot melt adhesive evenly distributed on the base fabric. 2. By setting up a spreading mechanism, the powdered hot melt adhesive in the powdered glue box is conveyed to the inside of the screen cylinder through the conveying channel. Then, the screen cylinder is driven to rotate by a dual-shaft motor, so that the powdered hot melt adhesive is evenly distributed in all parts of the screen cylinder and falls into the screen frame through the screen holes. After being further dispersed by the air impeller, the powder is evenly spread onto the base fabric, so that more hot melt adhesive can adhere during subsequent coating application, thereby improving the overall performance of the lining. 3. By setting the shock component in the dispersing mechanism, the shocker can be used to impact the screen cylinder, which can better disperse the powder hot melt adhesive. In addition, the shocker indirectly impacts the screen cylinder by impacting the shock ring, which can reduce the wear on the screen cylinder. 4. By setting up a preheating module, hot air can be delivered to the base fabric using the heater and fan in the preheating module during the base fabric conveying process. This allows the powder to be initially melted when the hot melt adhesive is subsequently applied to the base fabric, preventing the powder from scattering everywhere after being applied to the base fabric.

Detailed Implementation

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. 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 should fall within the scope of protection of the present invention.

[0030] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. Implementation Method 1

[0031] A coating apparatus for adhesive interlining coated fabrics, such as Figures 1-7As shown, the system includes a support base 1, a conveying module 2 for conveying the base fabric, and a coating mechanism 3 for coating the base fabric. The support base 1 has a conveying platform 21 on top that fits into the outlet of the conveying module 2. The coating mechanism 3 includes a triangular box 31 that provides space for coating the base fabric; the inlet of the triangular box 31 fits into the conveying platform 21, and after coating, it can convey the base fabric outwards. A fluid adhesive tank 32 is used to store the hot melt adhesive required for coating; the fluid adhesive tank 32 has a stirring rod that rotates synchronously with the shaft of the triangular box 31 to agitate the hot melt adhesive and maintain its fluidity. A coating assembly 33 is also included for coating the base fabric. The coating assembly 33 includes a coating roller 332 that rotates synchronously with the shaft of the triangular box 31 via gear transmission; the coating roller 332 has multiple openings of the same diameter evenly distributed on its wall. Hot melt adhesive can flow onto the base fabric through an opening; a folded tube 333 is set on the triangular box 31 and located inside the coating roller 332. The folded tube 333 is divided into two parts: a round tube and an L-shaped tube. The horizontal opening of the L-shaped tube is connected to the middle of the round tube. The hot melt adhesive must fill the lower half of the round tube before it can flow onto the coating roller 332 through the L-shaped tube; a glue delivery pipe 331 is used to connect the fluid glue tank 32 and the folded tube 333. The glue delivery pipe 331 is equipped with a valve; and a coating roller 334 is used to evenly spread the hot melt adhesive. The bottom opening of the L-shaped tube part of the folded tube 333 is oblique and partially contacts the coating roller 334. The hot melt adhesive will flow onto the coating roller 332 at the bottom of the coating roller 334 through the bottom opening of the L-shaped tube part of the folded tube 333. When the coating roller 332 rotates, the coating roller 334 will flatten the hot melt adhesive and spread it evenly onto the base fabric.

[0032] like Figure 4 As shown, the coating mechanism 3 also includes a scraper plate 34; the scraper plate 34 is hook-shaped and its hook part is arc-shaped and fits against the left inner oblique side wall of the triangular box 31. The scraper plate 34 is slightly higher than the glue roller 332. Before the base fabric is conveyed to the glue coating assembly 33, it will pass through the scraper plate 34. After the scraper plate 34 flattens the base fabric, the coating is applied to it by the glue coating assembly 33.

[0033] When coating the lining, the worker first feeds the end of the base fabric to the inlet of the conveying module 2. The base fabric is then conveyed by the rollers of the conveying module 2. After passing the conveying table 21, the base fabric enters the triangular box 31. The scraper 34 first contacts the base fabric and flattens it as the base fabric continues to be conveyed. At this time, the valve of the glue delivery pipe 331 needs to be opened to allow the hot melt adhesive to flow from the fluid glue tank 32 into the folded pipe 333 through the glue delivery pipe 331. After the lower half of the round tube of the folded tube 333 is filled, the hot melt adhesive can flow evenly through its L-shaped tube to the bottom of the coating roller 332. When the base fabric is transported to the coating roller 332, the hot melt adhesive in the coating roller 332 will be flattened by the coating roller 334 and applied to the base fabric through the holes on the coating roller 332. After the base fabric is finished, the coating of the lining fabric can be completed after the hot melt adhesive cools and solidifies. Implementation Method 2

[0034] Based on implementation method I, in order to improve the overall performance of the produced lining, such as Figures 8-12 As shown, a spreading mechanism is provided on the conveyor table 21. The spreading mechanism consists of a powder storage component 4, a powder screening component 5, a powder dropping component 6, and a vibration component 7. The spreading mechanism can spread powdered hot melt adhesive onto the base fabric, so that when the lining is coated in the subsequent coating process, the hot melt adhesive that can adhere to it is thicker, thereby improving the overall performance of the lining.

[0035] like Figure 1 , Figure 8 and Figure 9 As shown, the powder storage assembly 4 includes a powdered glue box 41 for storing powdered hot melt adhesive. The bottom of the powdered glue box 41 is composed of two inclined plates that rise towards the center, so that the powdered hot melt adhesive in the powdered glue box 41 can slide along the inclined plates to its two outlets. It also includes a conveying channel 42 for conveying the powdered hot melt adhesive in the powdered glue box 41. The powdered glue box 41 is provided with a conveying channel 42 at both outlets, which can realize bidirectional conveying of the powdered hot melt adhesive. The two conveying channels 42 extend from the opening of the powdered glue box 41 into the interior of the powder screening assembly 5, and a certain space is reserved between the outlets of the two conveying channels 42 to allow the powdered hot melt adhesive to enter into the powder screening assembly 5. The interior of the two conveying channels 42 is inclined along its conveying direction.

[0036] like Figure 1 , Figure 8 and Figure 9As shown, the powder sieving assembly 5 includes a cylindrical shell 51 that provides a sealed space for dispersing powdered hot melt adhesive; and a sieve cylinder 52 that can rotate within the cylindrical shell 51 and disperse the powdered hot melt adhesive evenly. The inner diameter of the sieve cylinder 52 gradually increases from its center to both sides, forming an inclined plane with a slope of less than 30° between its center and its ends. The aperture of the opening on the sieve cylinder 52 gradually increases from its center to both sides, which helps to disperse the powdered hot melt adhesive falling into the sieve cylinder 52 evenly. The assembly also provides a space for the rotation of the sieve cylinder 52. The dual-shaft motor 53 provides synchronous drive, ensuring that both ends of the sieve cylinder 52 are powered to rotate, resulting in more stable rotation and better powder dispersion. A full gear 54, located at the end of the output shaft of the dual-shaft motor 53, rotates synchronously with it. A gear ring 55, located on the sieve cylinder 52 and meshing with the full gear 54, also rotates with the output shaft of the dual-shaft motor 53, simultaneously driving the gear ring 55 and the sieve cylinder 52 to rotate.

[0037] like Figure 1 , Figure 10 and Figure 11 As shown, the powder dispensing assembly 6 includes a sieve frame 61 for distributing hot melt powder onto the base fabric. The sieve frame 61 is located at the bottom of the cylinder shell 51 and is 2cm-3cm away from the conveying table surface 21. The bottom of the sieve frame 61 has holes with the same inner diameter. The assembly also includes an air impeller 62 that can further disperse the hot melt powder evenly. The air impeller 62 rotates at a speed of no more than 30 revolutions per second and can only provide a slight breeze to the sieve frame 61, so that the powder falling from the sieve cylinder 52 is more dispersed.

[0038] As the base fabric passes through the conveyor table 21, the worker can pre-fill the powdered hot melt adhesive into the powdered adhesive box 41. The powder will then slide along the inclined plate inside the powdered adhesive box 41 into the conveying channels 42 on both sides, and then enter the middle of the screen cylinder 52 through the inclined surface inside the conveying channel 42. The worker only needs to start the dual-shaft motor 53, and under the action of the gear 54 and the gear ring 55, the screen cylinder 52 will rotate, dispersing the powder that falls into it evenly inside. The powder will fall into the screen frame 61 below through the holes opened on its outer wall. When the air impeller 62 symmetrically arranged in the screen frame 61 rotates, it will generate a breeze, further dispersing the powder. Finally, the powdered hot melt adhesive will be sprinkled onto the surface of the base fabric through the uniformly sized holes at the bottom of the screen frame 61.

[0039] like Figure 1 and Figure 12As shown, the vibration assembly 7 includes a housing 73 disposed at the end of the cylinder shell 51; four vibrators 71 symmetrically installed inside the housing 73 to assist in the dispersion of the powder hot melt adhesive in the sieve cylinder 52. The vibrators 71 can impact the sieve cylinder 52, and at the same time, the conveying channel 42 will also shake to a certain extent, which can help disperse the powder and promote the powder to fall from the conveying channel 42; and a vibration ring 72 that provides buffer protection for the sieve cylinder 52. The vibration ring 72 is disposed on the sieve cylinder 52 at the impact point of the vibrators 71 to buffer and protect the sieve cylinder 52, which can prevent the vibrators 71 from directly impacting the sieve cylinder 52 and causing the sieve cylinder 52 to be easily damaged.

[0040] like Figure 2 As shown, a preheating module 8 is provided at the conveying shaft of the conveying module 2 to heat the base fabric. The preheating module 8 consists of a fan and a heater, which are arranged alternately to uniformly preheat the base fabric conveyed into the preheating module 8, so that the base fabric has a certain temperature. When the powder hot melt adhesive is subsequently spread, some of the smaller powder particles can be directly melted into liquid and adhered to the base fabric, while the remaining powder is adhered, thus preventing the powder from flying around during the base fabric conveying process.

[0041] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein. The specification and embodiments are to be considered exemplary only, and the true scope and spirit of this application are indicated by the claims.
