Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, specifically to a fabric adhesive coating device. Background Technology

[0002] In the fabric processing industry, it is often necessary to coat the fabric surface with adhesive to meet the requirements of subsequent processing techniques, such as lamination and bonding. Existing fabric adhesive coating equipment has some shortcomings in the coating process. For example, it is difficult to guarantee the uniformity of adhesive application, easily resulting in areas with excessive or insufficient adhesive, which affects product quality. Therefore, it is necessary to develop a new type of fabric adhesive coating equipment to solve the problems existing in the current technology. Utility Model Content

[0003] In order to overcome the problems existing in the prior art, the purpose of this utility model is to provide a fabric adhesive coating device.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a fabric adhesive coating device, comprising:

[0005] Glue application platform, glue application components, glue delivery components;

[0006] The adhesive application platform includes a platform frame and a conveyor belt. The conveyor belt is installed above the platform frame, and the two ends of the conveyor belt are the inlet and outlet ends, respectively.

[0007] The glue application assembly includes a glue application frame, a drive unit, and a scraper. The two ends of the glue application frame are respectively mounted on both sides of the platform frame. The two ends of the drive unit are respectively connected to the two ends of the glue application frame, and the drive unit spans across the conveyor belt. The scraper is connected to the drive unit, and the blade of the scraper faces the conveyor belt.

[0008] The glue feeding assembly includes a guide trough, the end of which extends to the side of the glue coating assembly near the feed end of the conveyor belt, and the front end of which extends beyond the glue coating platform.

[0009] Main Working Principle: This fabric coating device mainly consists of three parts: a coating platform, a coating assembly, and a glue delivery assembly. These parts work together to apply glue to the fabric. The coating platform, serving as the foundation and support for the entire device and the fabric conveying component, comprises a platform frame and a conveyor belt. The platform frame provides stable structural support for the entire device, ensuring the proper installation and operation of all components. The conveyor belt is installed above the platform frame, with its two ends designated as the inlet and outlet. After the device starts, the conveyor belt begins to operate. The fabric is placed onto the conveyor belt from the inlet end. As the conveyor belt moves, the fabric is smoothly conveyed to the coating area, preparing for subsequent coating operations. The smooth operation of the conveyor belt ensures that the fabric does not shift or wrinkle during transport, thus ensuring the quality and uniformity of the coating. The main function of the glue delivery assembly is to accurately deliver the glue to the coating assembly for fabric coating. The glue delivery assembly includes a guide chute. The front end of the guide chute extends beyond the glue application platform, facilitating the operator's addition of glue. The rear end of the guide chute extends to the side of the glue application assembly near the conveyor belt feed end, ensuring the glue reaches the application area smoothly. When glue application is needed, the operator pours glue into the front end of the guide chute. Due to the chute's inclined angle, the glue flows along the chute towards its rear end under gravity. During this flow, the glue does not spill but is restrained by the chute walls, flowing steadily towards the glue application assembly. This achieves the delivery of glue from the external storage location to the application area, providing a continuous and stable glue supply to the glue application assembly.

[0010] The adhesive application assembly is the core component for applying adhesive to the fabric surface, consisting of an adhesive application frame, a drive unit, and a scraper. The adhesive application frame is mounted on both sides of the platform frame, providing a mounting base and support for the drive unit and scraper. The drive unit is connected to both ends of the adhesive application frame and spans across the conveyor belt, enabling it to move the scraper above the conveyor belt. The scraper is connected to the drive unit, with its blade tip facing the conveyor belt. When the fabric is conveyed to the adhesive application area, the drive unit activates, moving the scraper perpendicular to the fabric conveying direction. During this movement, the scraper tip contacts the fabric surface, evenly applying the adhesive from the guide chute onto the fabric surface.

[0011] In actual operation, the conveyor belt first starts operating, transporting the fabric to be coated from the inlet to the coating area. Simultaneously, the operator pours adhesive into the front of the guide chute, which flows under gravity towards the coating assembly. When the fabric reaches the coating area, the drive unit moves the scraper, which evenly spreads the adhesive from the guide chute onto the fabric surface. As the conveyor belt continues to operate and the scraper continues to move, the fabric is continuously coated with adhesive and finally output from the outlet, completing the entire fabric coating process. Through this collaborative working method, this fabric coating device can efficiently and stably perform fabric coating operations, improving production efficiency and coating quality.

[0012] Preferably, the drive unit includes a moving motor, a lead screw, and a slide bar;

[0013] The lead screw and the slide bar are arranged in parallel, and the two ends of the lead screw and the two ends of the slide bar are respectively connected to the two ends of the glue coating machine frame. The moving motor is installed at one end of the glue coating machine frame and is driven by the lead screw.

[0014] The scraper is driven by the lead screw and slidably connected to the slide rod.

[0015] Preferably, the scraper includes a base, a blade body, and a guide rod;

[0016] The base is driven to the drive unit, and the two sets of guide rods are respectively disposed on both sides of the base, and the two sets of guide rods are slidably connected to the base. The blade body is connected to the bottom of the two sets of guide rods.

[0017] Preferably, an elastic element is sleeved around the guide rod, with one end of the elastic element pressing against the blade body and the other end of the elastic element pressing against the base.

[0018] Preferably, the glue feeding assembly further includes a funnel, which is fixed to the front end of the guide trough.

[0019] Preferably, the guide trough includes a first trough section and a second trough section. The second trough section is provided with a connecting rod, and the two ends of the first trough section are provided with fastening grooves. The second trough section is connected to the first trough section by fastening the two ends of the connecting rod to the fastening grooves on both sides.

[0020] Preferably, the end of the second groove segment is bent toward the adhesive coating assembly.

[0021] Preferably, the second groove segment has fixing grooves on both sides of its end, and the first groove segment has fixing pins on both sides. When storage is required, the second groove segment is taken out and fixed above the first groove segment by the fixing grooves and fixing pins.

[0022] Preferably, the glue feeding assembly further includes a storage tank and a conveying pipe. The storage tank is located at the front end of the guide trough, and the conveying pipe is located below the storage tank. The storage tank is connected to the guide trough through the conveying pipe, and a valve is provided on the conveying pipe.

[0023] Preferably, the adhesive application platform further includes a first roller;

[0024] The first roller is located at the feed end of the conveyor belt, and the position of the first roller is lower than the upper surface of the conveyor belt. The fabric enters from below the first roller and is laid flat on the surface of the conveyor belt.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] This invention utilizes a squeegee in conjunction with a drive unit in an adhesive application assembly. The squeegee head is precisely aligned with the conveyor belt, and under the drive unit's influence, it moves with stable pressure across the fabric surface. This ensures even adhesive application, effectively preventing over- or under-application in certain areas, significantly improving the uniformity of adhesive application on the fabric surface. This provides a high-quality foundation for subsequent lamination, bonding, and other processing steps, effectively guaranteeing the quality of the final product. Attached Figure Description

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0035] Example 1

[0036] This embodiment discloses a fabric adhesive coating device, such as... Figures 1-4As shown, the device includes an adhesive application platform 1, an adhesive application assembly 2, and an adhesive delivery assembly 3. The adhesive application platform 1, serving as the foundation support and fabric conveying component of the entire device, consists of a platform frame 10 and a conveyor belt 11. The platform frame 10 provides stable structural support for the entire device, ensuring the proper installation and operation of all components. The conveyor belt 11 is installed above the platform frame 10, with its two ends designated as the inlet and outlet. After the device is started, the conveyor belt 11 begins to operate, and the fabric is placed onto the conveyor belt 11 from the inlet. As the conveyor belt 11 moves, the fabric is smoothly conveyed to the adhesive application area, preparing for subsequent adhesive application operations. The smooth operation of the conveyor belt 11 ensures that the fabric does not shift or wrinkle during transport, thus ensuring the quality and uniformity of the adhesive application. The main function of the adhesive delivery assembly 3 is to accurately deliver the adhesive to the adhesive application assembly 2 for fabric surface adhesive application. The glue delivery assembly 3 includes a guide trough 30. The front end of the guide trough 30 extends beyond the glue application platform 1, facilitating the operator's addition of glue. The rear end of the guide trough 30 extends to the side of the glue application assembly 2 near the feed end of the conveyor belt 11, ensuring the glue can smoothly reach the application area. When glue application is required, the operator pours the glue into the front end of the guide trough 30. Due to the inclined angle of the guide trough 30, the glue flows along the guide trough 30 towards the rear end under gravity. During this flow, the glue does not spill randomly but is constrained by the walls of the guide trough 30, flowing steadily towards the glue application assembly 2. This achieves the delivery of glue from the external storage location to the application area, providing a continuous and stable glue supply to the glue application assembly 2.

[0037] The adhesive coating assembly 2 is the core component for applying adhesive to the fabric surface, consisting of an adhesive coating frame 20, a drive unit 21, and a scraper 213. The adhesive coating frame 20 is mounted on both sides of the platform frame 10, providing a mounting base and support for the drive unit 21 and the scraper 213. The drive unit 21 is connected to both ends of the adhesive coating frame 20 and spans across the conveyor belt 11, enabling it to move the scraper 213 above the conveyor belt 11. The scraper 213 is connected to the drive unit 21, with its blade facing the conveyor belt 11. When the fabric is conveyed to the adhesive coating area along the conveyor belt 11, the drive unit 21 begins operation, driving the scraper 213 to move in a direction perpendicular to the fabric conveying direction. During this movement, the scraper 213's blade contacts the fabric surface, evenly applying the adhesive from the guide chute 30 to the fabric surface.

[0038] In actual operation, the conveyor belt 11 first starts operating, transporting the fabric to be coated from the feed end to the coating area. Simultaneously, the operator pours adhesive into the front end of the guide chute 30, which flows along the guide chute 30 towards the coating assembly 2 under gravity. When the fabric reaches the coating area, the drive unit 21 drives the scraper 213 to move, evenly applying the adhesive from the guide chute 30 onto the fabric surface. With the continuous operation of the conveyor belt 11 and the continuous movement of the scraper 213, the fabric is continuously coated with adhesive and finally output from the discharge end, completing the entire fabric coating process. Through this collaborative working method, the fabric coating device can efficiently and stably achieve fabric coating operations, improving production efficiency and coating quality.

[0039] In some optional embodiments, the drive unit 21 includes a moving motor 210, a lead screw 211, and a slide bar 212. The lead screw 211 and the slide bar 212 are arranged in parallel, and their two ends are respectively connected to the two ends of the glue applicator frame 20. The moving motor 210 is installed at one end of the glue applicator frame 20 and is drivenly connected to the lead screw 211. The scraper 213 is drivenly connected to the lead screw 211 and slidably connected to the slide bar 212.

[0040] After the mobile motor 210 starts, it drives the lead screw 211 to rotate. Since the scraper 213 is driven by the lead screw 211, the rotational motion of the lead screw 211 is converted into linear motion of the scraper 213 along the direction of the lead screw 211. At the same time, the scraper 213 is slidably connected to the slide bar 212, which acts as a guide to ensure that the scraper 213 remains stable during movement and does not deviate. This allows the scraper 213 to move precisely above the conveyor belt 11 to complete the uniform glue application operation.

[0041] In some optional embodiments, the scraper 213 includes a base 2130, a blade body 2131, and guide rods 2132. The base 2130 is drivenly connected to the drive unit 21, and two sets of guide rods 2132 are respectively disposed on both sides of the base 2130 and slidably connected to the base 2130. The blade body 2131 is connected to the bottom of the two sets of guide rods 2132.

[0042] When the drive unit 21 moves the base 2130, the base 2130 moves the blade 2131 together via the guide rod 2132. The guide rod 2132 is slidably connected to the base 2130, allowing the blade 2131 to make certain up-and-down adjustments according to the actual working conditions during movement, in order to adapt to the slight unevenness of the fabric surface and ensure that the blade 2131 and the fabric surface always maintain a suitable contact state, thereby achieving uniform adhesive application.

[0043] In some optional embodiments, an elastic element 2133 is sleeved around the guide rod 2132. One end of the elastic element 2133 is pressed against the blade body 2131, and the other end is pressed against the base 2130. During the movement of the scraper 213, when it encounters an uneven fabric surface, the pressure on the blade body 2131 will change. At this time, the elastic element 2133 will undergo elastic deformation according to the pressure change. If the fabric surface is convex, the blade body 2131 is subjected to upward pressure, and the elastic element 2133 is compressed, allowing the blade body 2131 to adapt to the convex part; if the fabric surface is concave, the elastic element 2133 will extend, pushing the blade body 2131 downward, so that the blade body 2131 can fully contact the concave part, thereby ensuring that the blade body 2131 always maintains a suitable contact pressure with the fabric surface, ensuring uniform glue application.

[0044] In some optional embodiments, the glue dispensing assembly 3 further includes a funnel 322, which is fixed to the front end of the guide trough 30. The funnel 322 guides the glue as it is added to the guide trough 30. After the glue is poured into the funnel 322, it flows accurately and smoothly into the guide trough 30, preventing glue from spilling outside the guide trough 30. This improves the accuracy and convenience of glue addition and reduces glue waste.

[0045] In some alternative embodiments, such as Figure 3 As shown, the guide trough 30 includes a first trough section 31 and a second trough section 32. The second trough section 32 is provided with a connecting rod 321. The ends of the first trough section 31 are provided with fastening slots 310 on both sides. The second trough section 32 is connected to the first trough section 31 by fastening the two ends of the connecting rod 321 into the fastening slots 310 on both sides. This detachable connection method allows the length of the guide trough 30 to be adjusted according to actual needs. When a longer guide trough 30 is needed, the two ends of the connecting rod 321 of the second trough section 32 are fastened into the fastening slots 310 at the ends of the first trough section 31, so that the second trough section 32 is connected to the first trough section 31 as a whole. When the second trough section 32 is not needed, it can be easily detached from the first trough section 31, improving the flexibility and applicability of the device.

[0046] In some alternative embodiments, the end of the second groove segment 32 bends towards the adhesive application assembly 2. This bending design allows the adhesive in the guide groove 30 to flow more precisely to the adhesive application assembly 2. As the adhesive flows through the second groove segment 32, the bend at the end changes its flow direction, directing it directly to a suitable position in front of the scraper 213, ensuring that the adhesive is utilized by the scraper 213 in a timely and accurate manner, thus improving adhesive application efficiency and quality.

[0047] In some alternative embodiments, such as Figure 4As shown, the second trough segment 32 has fixing grooves 320 on both sides of its end, and the first trough segment 31 has fixing pins 311 on both sides. When storage is required, the second trough segment 32 is removed and fixed above the first trough segment 31 by the fixing grooves 320 and fixing pins 311. This storage method can reduce the space occupied by the guide trough 30. After the second trough segment 32 is removed from the first trough segment 31, it is fixed above the first trough segment 31 by the fixing grooves 320 and fixing pins 311, making the overall structure of the guide trough 30 compact and easy to store and transport.

[0048] In some optional embodiments, the glue delivery assembly 3 further includes a storage tank 33 and a delivery pipe 34. The storage tank 33 is located at the front end of the guide trough 30, and the delivery pipe 34 is located below the storage tank 33. The storage tank 33 is connected to the guide trough 30 through the delivery pipe 34, and a valve is provided on the delivery pipe 34. Operators can pre-store a large amount of glue in the storage tank 33. When glue needs to be added to the guide trough 30, the valve on the delivery pipe 34 is opened, and the glue flows into the guide trough 30 under gravity. By controlling the opening degree of the valve, the flow rate of the glue can be adjusted, achieving a stable and continuous supply of glue and avoiding the problems of waste caused by adding too much glue at once or affecting the coating effect by adding too little glue.

[0049] In some optional embodiments, the adhesive application platform 1 further includes a first roller 12, which is disposed at the feed end of the conveyor belt 11 and positioned below the upper surface of the conveyor belt 11. The fabric enters from below the first roller 12 and lies flat on the surface of the conveyor belt 11. When the fabric enters the conveyor belt 11, it passes underneath the first roller 12 because the first roller 12 is positioned below the upper surface of the conveyor belt 11. The first roller 12 guides and flattens the fabric, allowing it to lie flat on the surface of the conveyor belt 11, preventing wrinkles and curling during the conveying process, ensuring the flatness of the fabric during adhesive application, and thus improving the adhesive application quality.

[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
