Description

Technical Field

[0001] This utility model relates to the technical field of double-sided drying equipment, specifically a double-sided drying equipment for knife-coated cloth. Background Technology

[0002] Knife-coated fabric is a material with specific production processes and multiple applications. Its main characteristics lie in its unique production process and material combination. It is usually based on the pressing of PVC film and mesh polyester filaments, and is produced through processes such as knife-coating layering, knife-coating lamination (melt method), and knife-coating calendering. Knife-coated fabric has many properties, such as high strength, lightweight, and excellent tear resistance. Due to its excellent physical properties and diverse surface effects, knife-coated fabric is widely used in many fields.

[0003] In the production of knife-coated fabric, one of the important processes is drying the fabric. The principle is to heat the fabric with drying equipment to evaporate the moisture on the fabric surface, thereby achieving the purpose of drying. During the drying process, it is necessary to control factors such as heating temperature, drying time and air circulation to ensure the drying effect.

[0004] Currently, when drying the squeegee cloth, it is first conveyed by a conveyor mechanism. During the conveying process, one side of the squeegee cloth is dried first. After drying, it is turned over and conveyed again by the conveyor mechanism to achieve the drying of the squeegee cloth.

[0005] However, during the drying process of the knife-coated cloth, since the drying of both sides of the knife-coated cloth is carried out sequentially, the drying time will be longer, thereby reducing the efficiency of drying the knife-coated cloth and easily causing heat waste. Utility Model Content

[0006] Therefore, the purpose of this utility model is to provide a double-sided drying device for knife-coated cloth, so as to solve the technical problem that in the process of drying knife-coated cloth, since the double-sided drying of knife-coated cloth is carried out sequentially, the drying time will be longer, thereby reducing the working efficiency of drying knife-coated cloth and easily causing heat waste.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a double-sided drying device for coated cloth, comprising a housing, with support legs fixedly connected to the four corners of the bottom of the housing, a feed inlet at one end of the housing, and a discharge outlet at the other end of the housing, a plurality of guide shafts rotatably connected inside the housing, a drying structure inside the housing, and fixed blocks that fit into the drying structure fixedly connected to the top and bottom of the housing, with a plurality of air inlets on the side of the fixed blocks near the drying structure, and connecting blocks connected to both ends of the housing by a plurality of fixed rods, the connecting blocks fitting into the feed inlet and the discharge outlet, a plurality of second air outlets on the surface of the connecting blocks, and each fixed block being connected to the corresponding connecting block via a second pipe.

[0008] By adopting the above technical solution, the hot air generated by the drying structure can dry the scraper cloth inside the shell. The dried hot air can enter the fixed block through the air inlet, and then be transported to the corresponding connecting block through the second pipe. Finally, it is sprayed out through the second air outlet on the surface of the connecting block. When the scraper cloth enters the shell through the inlet, it needs to pass through the connecting block at one end of the inlet first. This allows the hot air sprayed from the connecting block to achieve preliminary drying of the scraper cloth. The scraper cloth has a certain temperature before reaching the main drying area, which facilitates the uniform distribution of heat during the subsequent drying process. When the scraper cloth is dried and discharged through the outlet, it can be dried again through the connecting block near the outlet, avoiding insufficient drying and helping to ensure product quality. This structure can realize the reuse of heat energy, reduce heat energy waste, and thus improve drying efficiency. It can also realize hot air circulation through the fixed block, air inlet, second pipe and connecting block, thus achieving energy saving effect.

[0009] The present invention is further configured such that the drying structure includes a fixed plate, a drying device, a drying block, a first pipe and a first air outlet. A fixed plate is fixedly connected to one side of the housing, and a drying device is installed on the fixed plate. Drying blocks are fixedly connected to the top and bottom of the housing, and a plurality of first air outlets are provided on the adjacent side of each drying block. Both ends of the drying device are connected to the corresponding drying blocks through the first pipe.

[0010] By adopting the above technical solution, the hot air generated by the drying device can be transported to the drying block through the first pipe, and then evenly sprayed onto the surface of the knife-coated cloth through the first air outlet on the surface of the drying block. Since the drying block is located at the top and bottom of the shell, a set of drying blocks are located on both sides of the knife-coated cloth, thereby achieving double-sided drying of the knife-coated cloth.

[0011] The present invention is further configured such that a set of brushes are movably connected to the surface of the connecting block near one end of the feed inlet, and the side of the connecting block near the brushes is configured as an inclined structure.

[0012] By adopting the above technical solution, when the scraper cloth enters the housing through the feed inlet, it can first pass through the connecting block near the feed inlet. The surface of the scraper cloth can then be cleaned by the brush, which facilitates better drying of the scraper cloth. At the same time, the connecting block is set with a sloping structure on the side near the brush, so that the impurities that fall off during cleaning can fall off through the sloping surface, preventing them from entering the connecting block and affecting the initial drying of the scraper cloth by the connecting block.

[0013] The present invention is further configured such that a set of movable doors are connected to one side of the housing via a hinge, and the movable doors and the housing are connected by a latch.

[0014] By adopting the above technical solution, it is convenient to inspect and maintain the internal structure of the housing by opening the movable door, thereby extending the service life of the equipment. At the same time, the locking design can keep the movable door in the closed state, thereby ensuring the airtightness of the equipment during operation and preventing heat loss from the equipment from affecting the drying effect.

[0015] The present invention is further configured such that the first air outlet on the surface of each drying block matches the air inlet on the surface of the fixed block.

[0016] By adopting the above technical solution, the hot air ejected from the first air outlet dries the knife-coated cloth, and then enters the fixed block through the air inlet, thereby being delivered to the corresponding connecting block for ejection. This allows the hot air to be reused, thereby improving the drying efficiency and contributing to energy saving.

[0017] The present invention is further configured such that the brush and the connecting block are connected by bolts.

[0018] By adopting the above technical solution, the bolt connection method facilitates quick replacement of the brush, thereby avoiding the impact of brush wear or damage on the cleaning of the scraper cloth.

[0019] The present invention is further configured such that the movable door is made of a transparent material.

[0020] By adopting the above technical solution, when drying the knife-coated cloth on both sides, the operator can directly observe the internal drying situation through the movable door, which makes it easier for the operator to discover and solve problems in the drying process in a timely manner.

[0021] In summary, the present invention has the following main advantages:

[0022] This invention dries the scraped cloth inside the housing using a drying structure. Simultaneously, the gas generated by the drying device is transported to the connecting block via a fixed block, inlet, and second pipe, and then ejected through a second outlet on the surface of the connecting block. Therefore, when the scraped cloth enters the housing, it is initially dried by the hot air ejected from the connecting block, ensuring it has a certain temperature upon entering the housing, facilitating even heat distribution during subsequent drying. Furthermore, when the scraped cloth exits the housing, it can be re-dried by the hot air ejected from the connecting block, preventing insufficient drying and helping to ensure product quality. This structure allows for the reuse of heat energy, reducing waste and improving drying efficiency. The fixed block, inlet, second pipe, and connecting block also enable hot air circulation, resulting in energy savings. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] A double-sided drying device for knife-coated cloth, such as Figure 1-4As shown, the device includes a housing 1. Support legs 2 are fixedly connected to the four corners of the bottom of the housing 1, providing support and ensuring the stability of the equipment. One end of the housing 1 has an inlet 5, and the other end has an outlet 6. This allows the scraper cloth to enter the housing 1 through the inlet 5 for drying and exit through the outlet 6 after drying, providing a clear path for the drying process. A set of movable doors 3 is connected to one side of the housing 1 via hinges, allowing operators to open the doors to inspect the internal structure of the housing 1. Inspection and maintenance facilitate the extension of equipment lifespan. The movable door 3 and the housing 1 are connected by a latch 4. A rubber layer is provided between the movable door 3 and the housing 1. Therefore, when the blade-coated cloth is dried, the movable door 3 can be kept closed by the latch 4 to prevent heat loss, thus allowing for better drying of the blade-coated cloth. The movable door 3 is made of transparent material, which allows the operator to directly observe the internal drying process through the movable door 3, making it easier for the operator to promptly identify and resolve problems during the drying process, thereby achieving better drying of the blade-coated cloth.

[0031] Subsequently, several guide shafts 20 are rotatably connected inside the housing 1, allowing the scraper cloth to pass through each guide shaft 20 in sequence. This provides a clear movement path for the scraper cloth via the guide shafts 20, thus enabling better drying. A drying structure is provided inside the housing 1 to facilitate drying of the scraper cloth using the heat generated by the drying structure. Fixing blocks 12, which fit into the drying structure, are fixedly connected to the top and bottom of the housing 1. Several air inlets 13 are provided on the side of the fixing blocks 12 closest to the drying structure. Connecting blocks 15 are connected to both ends of the housing 1 via several fixing rods 14. The connecting blocks 15 fit into the feed inlet 5 and the discharge outlet 6. Several second air outlets 16 are provided on the surface of the connecting blocks 15. Each fixed block 12 is connected to the corresponding connecting block 15 via a second pipe 19. Therefore, when the hot air generated by the drying structure dries the scraper cloth, the dried hot air can enter the fixed block 12 through the air inlet 13, and then be transported to the connecting block 15 through the second pipe 19, and finally discharged through the second air outlet 16. Thus, when the scraper cloth enters or exits the housing 1, it can be pre-dried and re-dried by the hot air sprayed from the connecting block 15, which facilitates the uniform distribution of heat in the subsequent drying process, improves drying efficiency, and avoids insufficient drying. This structure can realize the reuse of heat energy, reduce heat energy waste, and thus improve drying efficiency.

[0032] The drying structure includes a fixed plate 7, a drying device 8, a drying block 9, a first pipe 10, and a first air outlet 11. The fixed plate 7 is fixedly connected to one side of the housing 1, and the drying device 8 is installed on the fixed plate 7. The drying blocks 9 are fixedly connected to the top and bottom of the housing 1, and several first air outlets 11 are provided on the adjacent side of the drying blocks 9. Both ends of the drying device 8 are connected to the corresponding drying blocks 9 through the first pipe 10, so that the hot air generated by the drying device 8 can be transported to the drying blocks 9 through the first pipe 10, and then evenly sprayed onto the surface of the knife-coated cloth through the first air outlets 11 on the surface of the drying blocks 9. Since the drying blocks 9 are located at the top and bottom of the housing 1, a set of drying blocks 9 can be located on both sides of the knife-coated cloth, thereby realizing double-sided drying of the knife-coated cloth.

[0033] Meanwhile, the first air outlet 11 on the surface of each drying block 9 matches the air inlet 13 on the surface of the fixed block 12, so that the hot air ejected from the first air outlet 11 can circulate through the fixed block 12, the air inlet 13, the second pipe 19 and the connecting block 15 after drying the knife-coated cloth, thereby achieving the effect of energy saving.

[0034] Furthermore, a set of brushes 17 are movably connected to the surface of the connecting block 15 near the feed inlet 5. Therefore, when the scraper cloth enters the housing 1 for drying, it can first pass through the connecting block 15, so that the brushes 17 can clean both sides of the scraper cloth, avoiding impurities from affecting the subsequent drying of the scraper cloth. The brushes 17 and the connecting block 15 are connected by bolts 18. The connection method of bolts 18 facilitates the quick replacement of brushes 17, thereby avoiding the impact of wear or damage to brushes 17 on the cleaning of the scraper cloth. The connecting block 15 is set with a sloping structure on the side near the brushes 17, so that impurities cleaned by the brushes 17 can fall through the sloping structure, avoiding them from entering the connecting block 15 and affecting the initial drying of the scraper cloth.

[0035] The drying device 8 in this embodiment is an existing structure. Its principle relies on the convective heat transfer between hot air and the surface of the material to transfer heat. The heated air forms an airflow under the action of equipment such as a fan, flows over the surface of the material, and transfers heat to the material, causing the moisture in the material to evaporate into water vapor. At the same time, when drying the knife-coated cloth, an external winding structure is set at one end of the discharge port, which can reduce the interference of workers during the drying process of the knife-coated cloth and improve work efficiency.
