Description

Technical Field

[0001] This utility model relates to the field of film coating technology, and in particular to a film coating device for woven bags. Background Technology

[0002] Woven bags are a common type of packaging container made from plastic raw materials such as polypropylene through processes such as drawing and weaving. They have good toughness and a certain load-bearing capacity, and are also characterized by low cost, high strength, and lightweight portability. They are widely used in many industries such as agriculture, chemical industry, and building materials to hold various granular, powdery, and lumpy items, playing an important role in the transportation and storage of goods.

[0003] Laminating woven bags effectively enhances their moisture-proof properties, preventing the contents from deteriorating or being damaged due to moisture. Lamination also improves the abrasion resistance of the bags, reducing friction during handling and transportation, and extending their lifespan. From an aesthetic and labeling perspective, the surface of laminated woven bags is smoother and more even, making it easier to print clear and durable patterns and text, which is beneficial for product brand image display and promotion, and facilitates product circulation and sales in the market. Therefore, woven bag laminating equipment has emerged.

[0004] Traditional woven bag laminating equipment applies glue between the back of a plastic film and the surface of the woven bag, then uses pressure to bond the two together. While this method can achieve lamination to some extent, the use of glue containing large amounts of harmful substances such as formaldehyde limits its application in high-demand fields like food processing. Furthermore, existing hot-press laminating equipment often uses an integral heating plate, heating the entire laminating area. When dealing with woven bags of varying thicknesses, materials, and weave textures, this can easily lead to issues such as insecure lamination in certain areas, uneven lamination thickness, or damage to the woven bag due to overheating. This affects lamination quality and production efficiency, failing to meet the diverse and high-quality woven bag laminating needs. Utility Model Content

The output end of the electric actuator 404 is fixedly connected to the arc-shaped rubber pressure plate 405. Due to its arc design, the arc-shaped rubber pressure plate 405 can better fit the shape of the woven bag. Under the push of the electric actuator 404, the coating material and the woven bag are evenly squeezed to ensure tight adhesion and no air bubbles. The top front and rear sides of the arc-shaped rubber pressure plate 405 are fixedly connected to the balance sleeve 4. 06. The balance rod 406 provides stable guidance for the lifting and lowering of the arc-shaped rubber pressure plate 405, preventing it from shifting or swaying during movement and ensuring the accuracy of the extrusion action. The tops of the two balance rods 406 are respectively fixedly connected to the front and rear sides of the inner top wall of the top plate 403, further enhancing the stability and integrity of the entire structure. The winding mechanism 5 includes two placement frames 501. The right ends of the two placement frames 501 are respectively fixedly connected to the front and rear ends of the left side of the worktable 1, providing stable installation support for the winding roller 502 and ensuring that the device will not shake or shift during the winding process. The internal components are all rotatably connected to a take-up roller 502, which can rotate smoothly to facilitate the orderly winding of the laminated woven bags, thus achieving product sorting and storage. A take-up motor 503 is fixedly installed on the bottom left side of the workbench 1. The take-up motor 503 provides a stable power source for the take-up roller 502, ensuring that the winding action is continuous and stable. The output end of the take-up motor 503 and the rear side of the outer wall of the take-up roller 502 are both engaged with a second transmission belt 504. The second transmission belt 504 can efficiently transmit power, so that the take-up roller 502 rotates at a predetermined speed, ensuring that the winding speed matches the production rhythm.

[0034] Reference Figure 1 , Figure 2 and Figure 3The tension adjustment mechanism 6 includes two electric telescopic rods 601. The two electric telescopic rods 601 can precisely adjust their telescopic length according to a preset program, thereby flexibly controlling the tension adjustment range to meet the tension requirements of woven bag materials and coated materials of different materials and thicknesses during transmission. The output ends of both electric telescopic rods 601 are fixedly connected to a first crossbar 602. The first crossbar 602 provides a stable connection base for subsequent components, ensuring the integrity and continuity of the entire tension adjustment structure. A second crossbar 603 is fixedly connected to the top of the first crossbar 602. The second crossbar 603 can further expand the effective area of ​​tension adjustment, making the tension adjustment more uniform and comprehensive in its application to the material, effectively avoiding local tension imbalance. The stabilizing mechanism 7 includes an L-shaped fixing plate 701. The rear side of the L-shaped fixing plate 701 is fixedly connected to the front side of the workbench 1. Its unique L-shaped design provides a stable and reliable mounting support, enhancing the fixing strength of the stabilizing mechanism 7 on the workbench 1. The front right end of the L-shaped fixing plate 701 is fixed... Two damping hinges 702 are installed, which allow the rotating plate 703 to rotate flexibly under certain resistance. This ensures both the unloading effect on the front end of the raw material and the relative stability of the structure. The rotating plate 703 is fixedly connected to the rear right end of each of the two damping hinges 702. As a component that directly contacts and acts on the raw material, the rotating plate 703 can adaptively adjust its angle according to the movement state of the raw material to achieve a precise balanced unloading effect. The upper and lower rear ends of the rotating plate 703 are fixedly connected to cylindrical rotating blocks 704. The cylindrical rotating blocks 704 provide a smooth rotation interface for the connection between the rotating plate 703 and the material roller 301, reducing friction and jamming. The front middle of each of the two material rollers 301 has a cylindrical groove 705. The cylindrical groove 705 and the cylindrical rotating block 704 are tightly engaged to ensure that the connection between the rotating plate 703 and the material roller 301 is firm and stable, so that the balanced unloading function can be effectively performed, ensuring the stability and quality reliability of the woven bag raw material and the coated raw material during the transmission and processing.

[0035] Reference Figure 1 and Figure 2A control console 8 is fixedly installed on the top of the L-shaped fixed plate 701. The control console 8 serves as the control center of the entire device, facilitating centralized management and operation of the equipment by the operators, thus improving operational convenience and efficiency. Multiple control buttons 9 are fixedly connected to the top of the control console 8, allowing the operators to control the entire device and precisely control the operating status of each part of the device to meet diverse processing needs. Anti-slip pads 10 are fixedly connected to the bottom of the four corners of the workbench 1 and the bottom of the material fixing platform 2. The anti-slip pads 10 effectively increase the friction between the device and the ground, preventing displacement or shaking during operation and ensuring the stability and safety of the equipment. The bottoms of the multiple anti-slip pads 10 are all designed with anti-slip properties, further enhancing the anti-slip effect and ensuring that the device can be placed stably under various ground conditions, providing reliable basic support for woven bag laminating processing, which is conducive to improving product processing quality and production efficiency.

[0036] Working principle: A material conveying mechanism 3 is provided on the material fixing platform 2. The outer walls of two material rollers 301 penetrate the upper and lower ends of the front side of the material fixing platform 2, respectively. Limiting plates 302 are fixedly connected to the rear side of the outer walls of the two material rollers 301. These limiting plates 302 can prevent the cylindrical material 303 from axial displacement during rotation. When the cylindrical material 303 needs to be installed, it is respectively clamped in the middle of the two material rollers 301. Then, the cylindrical material 303 can be further fixed by the threaded groove 304 opened at the front end of the outer wall of the material roller 301 and the fastening nut 305 threadedly connected thereto, ensuring its stability during operation. Belt grooves 306 are opened at the rear end of the outer wall of the material rollers 301. The output end of the drive motor 307 fixedly installed on the right side of the material fixing platform 2 is connected to the two rollers 301. The belt groove 306 is fitted with a transmission belt 308. When the drive motor 307 starts, the rotation of its output end is transmitted to the two material rollers 301 through the transmission belt 308, so that the two material rollers 301 rotate synchronously. Since the cylindrical material 303 is fastened to the material roller 301, the cylindrical material 303 also rotates. During the operation, when the material roller 301 at the top drives the cylindrical material 303 to rotate, the woven bag material on the cylindrical material 303 will be gradually transferred to the lamination processing area on the worktable 1. By precisely controlling the speed of the drive motor 307, the transmission speed of the woven bag material can be precisely controlled to meet the lamination processing requirements of different thicknesses, ensuring that the woven bag material can be stably and efficiently transferred from the material fixing table 2 to the subsequent lamination processing process.

[0037] Furthermore, after the woven bag material is transferred to the workbench 1 via the material conveying mechanism 3, the heat coating mechanism 4 begins to operate. The heating tank 401 is located in the middle of the top wall of the workbench 1. The electric heating wire 402 inside generates heat after being energized, heating the coating material placed above the heating tank 401 to a suitable temperature, giving the coating material good adhesion. The top plate 403 is fixed to the top of the workbench 1, and the electric push rod 404 is installed on the inner top wall of the top plate 403. When a coating operation is required, the electric push rod 404 is activated. Its output end pushes the arc-shaped rubber pressure plate 405 downward. The balance sleeves 406 on the front and rear sides of the top of the arc-shaped rubber pressure plate 405 play a stabilizing and guiding role, ensuring that the arc-shaped rubber pressure plate 405 can descend smoothly and vertically. During the downward movement of the arc-shaped rubber pressure plate 405, it presses the heated coating material tightly onto the surface of the woven bag material. Due to its arc-shaped design, it can better fit the shape of the woven bag, making the coating and the woven bag adhere tightly and evenly, ensuring the coating quality. Under certain pressure and temperature, The coating material is firmly adhered to the woven bag, completing the coating process. After coating, the woven bag needs to be rolled up. At this time, the two placement frames 501 in the winding mechanism 5 are fixed to the front and rear ends of the left side of the workbench 1, respectively. The winding roller 502 is rotatably connected inside the placement frame 501. The winding motor 503 is installed at the bottom left side of the workbench 1. When the winding motor 503 starts, its output end drives the winding roller 502 to rotate through the transmission belt 504. As the winding roller 502 rotates, the coated woven bag is gradually rolled up onto the winding roller 502. By reasonably controlling the speed of the winding motor 503, the winding speed can be adjusted to match the working rhythm of the material conveying mechanism 3 and the hot coating mechanism 4, avoiding problems such as excessive stretching of the woven bag or untimely winding. The whole winding process is smooth and orderly, ensuring that the coated woven bag can be neatly rolled up, which is convenient for subsequent storage, transportation and use, and improves the automation level and production efficiency of the entire woven bag coating production line.
