Description

Technical Field

[0001] This utility model relates to the technical field of food packaging bag processing, and in particular to a drying and cooling device for food packaging bags with good sealing performance. Background Technology

[0002] A food packaging bag drying and cooling device is a specialized piece of equipment used in food packaging production lines. It is primarily used to dry and cool packaging bags after processes such as printing, coating, or cleaning. This device typically consists of a hot air drying system and a cooling system. The hot air system removes moisture or solvent residue from the surface of the packaging bags by evenly blowing hot air, while the cooling system rapidly lowers the temperature of the packaging bags using natural wind or forced ventilation, preventing deformation or sticking during subsequent processes. Through continuous drying and cooling, this device not only improves the drying efficiency and product quality of the packaging bags but also ensures the continuity and stability of the production line. It is one of the most important pieces of equipment in the food packaging industry for improving production efficiency and ensuring food safety.

[0003] Existing technology, such as application number CN202120705844.1, discloses a food packaging bag cleaning device. This invention features an annular nozzle to rinse the food packaging bag from two directions, a support rod to reduce cleaning fluid residue, and an inclined trough to increase the steam drying area, thus accelerating the cooling and drying cycle. The structure is simple and compact, improving the efficiency of cleaning and drying.

[0004] Existing food packaging bag washing devices leave a large amount of water adhering to the surface of the bags after rinsing with clean water. This residual water is difficult to evaporate naturally in a short time, resulting in the subsequent drying process requiring a large amount of heat energy and time. This significantly reduces overall production efficiency and increases energy costs. Incomplete drying may also affect the appearance quality of the packaging bags and the smooth progress of subsequent processes. Utility Model Content

[0005] In view of the problems of excessive residual moisture on the surface of existing packaging bags after rinsing, resulting in low drying efficiency, high energy consumption, and potential impact on product quality, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a food packaging bag drying and cooling device with good sealing performance, which aims to solve the problem that excessive residual moisture on the surface of existing packaging bags after rinsing leads to low drying efficiency, high energy consumption, and may affect product quality.

[0007] To solve the above technical problems, this utility model provides the following technical solution: a food packaging bag drying and cooling device with good sealing performance, including an outer casing, a rinsing mechanism, a scraping mechanism and a cooling mechanism. The rinsing mechanism includes a strip pipe fixedly installed in the upper part of the outer casing. A flat nozzle is fixedly installed on the surface of the strip pipe through a water supply pipe. The scraping mechanism includes a mounting bracket fixedly installed on the inner surface of the outer casing. A sliding block is movably installed on the inner side of the mounting bracket. A scraper is fixedly installed on one side surface of the sliding block. A drying box is fixedly installed inside the upper part of the outer casing of the equipment, and the cooling mechanism includes a water collection tank fixedly installed inside the outer casing of the equipment.

[0008] As a preferred embodiment of the food packaging bag drying and cooling device with good sealing performance described in this utility model, a number of guide rollers are rotatably installed on the inner side of the outer casing of the device.

[0010] As a preferred embodiment of the food packaging bag drying and cooling device with good sealing performance described in this utility model, the water supply pipe is obliquely fixedly installed on the inner side of the strip pipe, and the water supply pipe and the flat nozzle are respectively installed on the upper and lower sides of the food packaging bag.

[0011] As a preferred embodiment of the food packaging bag drying and cooling device with good sealing performance described in this utility model, the inner surface of the mounting frame is provided with a sliding groove, and a sliding rod is fixedly installed inside the sliding groove.

[0012] In a preferred embodiment of the food packaging bag drying and cooling device with good sealing performance described in this utility model, the sliding block is slidably mounted on the surface of the sliding rod, and a spring structure is installed between the upper surface of the sliding block and the upper inner part of the sliding groove.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: 1. This utility model, through the setting of a scraping mechanism, after the upper and lower surfaces of the food packaging bag are washed by the rinsing mechanism, the food packaging bag is guided and conveyed by the guide roller. The scraper of the scraping mechanism is in close contact with the upper and lower surfaces of the food packaging bag to scrape off the excess water remaining on the surface of the food packaging bag. After drying in the drying box, the amount of water entering the drying process is effectively reduced, thereby significantly improving drying efficiency and reducing energy consumption. At the same time, it avoids appearance quality problems and subsequent process obstruction caused by moisture residue, and improves the overall production continuity and economy.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0019] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a food packaging bag drying and cooling device with good sealing performance. This food packaging bag drying and cooling device with good sealing performance includes an outer casing 1, a rinsing mechanism 3, a scraping mechanism 4 and a cooling mechanism 5. The rinsing mechanism 3 includes a strip pipe 302 fixedly installed in the upper part of the outer casing 1. A flat nozzle 304 is fixedly installed on the surface of the strip pipe 302 through a water supply pipe 303. The scraping mechanism 4 includes a mounting bracket 401 fixedly installed on the inner surface of the outer casing 1. A sliding block 404 is movably installed on the inner side of the mounting bracket 401. A scraper 405 is fixedly installed on one side surface of the sliding block 404.

[0020] Several sets of guide rollers 2 are rotatably installed on the inner side of the outer casing 1 of the equipment.

[0021] A water storage tank 301 is fixedly installed on the upper surface of the outer casing 1 of the equipment, and a strip pipe 302 is fixedly installed on the lower surface of the water storage tank 301. A water inlet is installed on one corner of the upper surface of the water storage tank 301.

[0022] The water delivery pipe 303 is fixedly installed at an angle inside the strip pipe 302, and the water delivery pipe 303 and the flat nozzle 304 are respectively installed on the upper and lower sides of the food packaging bag.

[0023] A sliding groove 402 is provided on the inner surface of the mounting bracket 401, and a sliding rod 403 is fixedly installed inside the sliding groove 402.

[0024] The sliding block 404 is slidably mounted on the surface of the sliding rod 403, and a spring structure 406 is installed between the upper surface of the sliding block 404 and the upper inner part of the sliding groove 402.

[0025] During use, the food packaging bags are guided and conveyed inside the outer casing 1 of the equipment by several sets of guide rollers 2. Clean water in the water storage tank 301 is injected through the water inlet and conveyed through the water supply pipe 303 to the flat nozzles 304 on the upper and lower sides to rinse the upper and lower surfaces of the packaging bags. After rinsing, the packaging bags continue to be conveyed forward and enter the scraping mechanism 4. The sliding block 404 in the sliding groove 402 inside the mounting frame 401 drives the scraper 405 to stick tightly to the surface of the packaging bag under the action of the spring structure 406, and scrapes off the residual moisture. Subsequently, the packaging bags enter the drying chamber 407 for drying. Since the surface moisture has been greatly reduced, the drying efficiency is significantly improved and the energy consumption is reduced. Example 2

[0026] Reference Figure 1 , Figure 2 and Figure 4This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a drying box 407 is fixedly installed in the upper part of the outer casing 1 of the equipment, and the cooling mechanism 5 includes a water collection tank 502 fixedly installed inside the outer casing 1 of the equipment.

[0027] A guide plate 501 is fixedly installed on the inner side of the outer casing 1 of the equipment, and the lower outlet of the guide plate 501 is fixedly installed on one side of the water collection tank 502.

[0028] A heat-conducting film 503 is fixedly installed on the inner surface of the water collection tank 502, and a drain outlet is provided in the lower inner part of the water collection tank 502.

[0029] During operation, after the food packaging bags are rinsed and scraped inside the outer casing 1 of the equipment, they enter the drying chamber 407, which is fixedly installed in the upper inner part, for drying. Subsequently, the packaging bags continue to be conveyed forward into the cooling mechanism 5. The wastewater generated after rinsing is guided downward through the guide plate 501 into the water collection tank 502. A heat-conducting film 503 is fixedly installed on the inner surface of the water collection tank 502, so that the low-temperature wastewater and the packaging bags can exchange heat indirectly through the heat-conducting film 503, thereby cooling the packaging bags. After the wastewater is collected in the water collection tank 502, it is discharged through the drain outlet opened in the lower inner part. The entire cooling process utilizes the low-temperature resources of the wastewater, which not only avoids the pollution risk caused by direct contact between the packaging bags and wastewater, but also effectively recovers and utilizes the cold energy, reduces cooling energy consumption, improves production efficiency, and ensures product safety and quality stability.

[0030] The remaining structure is the same as that in Example 1.

[0031] Based on embodiments 1-2, the working principle of this utility model is as follows: Food packaging bags are guided and conveyed within the outer casing 1 of the equipment by several sets of guide rollers 2. Clean water from the water tank 301 is injected through the water inlet and transported via the water supply pipe 303 to the flat nozzles 304 on both the upper and lower sides to rinse the upper and lower surfaces of the packaging bags. After rinsing, the packaging bags continue to be conveyed forward and enter the scraping mechanism 4. The sliding block 404 in the sliding groove 402 inside the mounting frame 401, under the action of the spring structure 406, drives the scraper 405 to adhere tightly to the surface of the packaging bag, scraping away residual moisture. Subsequently, the packaging bags enter the drying chamber 407 fixedly installed in the upper inner part for drying. Since the surface moisture has been significantly reduced, the drying process... Efficiency is significantly improved and energy consumption is reduced. After drying, the packaging bags enter the cooling mechanism 5. The wastewater generated after rinsing is guided downward through the guide plate 501 into the water collection tank 502. A heat-conducting film 503 is fixedly installed on the inner surface of the water collection tank 502, so that the low-temperature wastewater and the packaging bags can exchange heat indirectly through the heat-conducting film 503 to cool down the packaging bags. After the wastewater is collected in the water collection tank 502, it is discharged through the drain outlet opened in the lower part of the tank. The entire cooling process utilizes the low-temperature resources of the wastewater, which not only avoids the pollution risk caused by direct contact between the packaging bags and the wastewater, but also effectively recovers and utilizes the cold energy, reduces cooling energy consumption, improves production efficiency, and ensures product safety and quality stability.
