Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a fully biodegradable bag water-based ink printing drying device. Background Technology

[0002] In the packaging and printing industry, fully biodegradable bags are widely used in food packaging, daily necessities packaging and other fields because of their natural degradability and environmental friendliness. In order to meet the needs of product labeling, brand promotion and other requirements, patterns, text and other information need to be printed on the surface of fully biodegradable bags through water-based ink printing process during the production process. In a Chinese patent with publication number CN220262363U entitled "A Drying Device for Printing Packaging Bags", a drying device is set up. When the blower generates airflow, the airflow enters the heating chamber through the through hole above the heating chamber. The heat accumulated inside the heating chamber mixes with the airflow. After generating hot airflow, it is discharged through the exhaust port of the duct below the heating chamber, thus drying the material below the exhaust port. This facilitates the drying of the printed material and avoids contamination of other materials by incompletely dried material during the collection process, thereby ensuring the quality of material processing and guaranteeing the working efficiency of the drying device. When the above-mentioned equipment is in use, the air outlet components are relatively fixed, which easily leads to uneven heat distribution on different parts of the biodegradable bag (one side receives more heat, and the other side receives less heat). This significant difference in heat distribution seriously interferes with the drying process of water-based ink on the surface of the biodegradable bag. In addition, biodegradable bags of different specifications (thickness) require different drying conditions, which makes it difficult for most fixed air nozzles to provide the most suitable drying environment for biodegradable bags with different characteristics. In order to solve the above problems, the inventors have proposed a fully biodegradable bag water-based ink printing drying device. Utility Model Content

[0003] To address the issues of uneven heat distribution in different parts of the biodegradable bag due to the relatively fixed air outlet components, and the different drying conditions required for biodegradable bags of different sizes (thicknesses), which make it difficult for most fixed air nozzles to provide a suitable drying environment, the purpose of this invention is to provide a fully biodegradable bag water-based ink printing drying device.

[0004] To solve the above technical problems, this utility model adopts the following technical solution: a fully biodegradable bag water-based ink printing drying device, including a base, a housing fixedly connected to the top of the base, inlet and outlet grooves symmetrically opened at the center of both sides of the housing, two sets of guide sleeves symmetrically fixedly connected to the inner walls of the front and rear of the housing near the top center, guide shafts slidably inserted inside the guide sleeves, tension springs fixedly connected to the side ends of the guide shafts, and the other end of the tension springs fixedly connected to the inner wall of the guide sleeves, a connecting plate fixedly connected between the ends of the two guide shafts away from the guide sleeves, a blower head fixedly connected to the center of the bottom of the connecting plate, and the two blowers head are symmetrically distributed, two sets of limiting shafts symmetrically fixedly connected to the inner walls of the front and rear of the housing near the center, and the blowers head are slidably connected to the limiting shafts, U-shaped mounting seats symmetrically fixedly connected to the side walls of the housing near the top center, a stop rod rotatably connected between the inner walls of the U-shaped mounting seats, an auxiliary wheel rotatably connected to the side end of the stop rod away from the U-shaped mounting seat, and the auxiliary wheel is in contact with the connecting plate.

[0006] Preferably, a second gear is rotatably connected to the top of the housing near the center, and the second gear is located at the center of two U-shaped mounting seats. A first gear that meshes with the second gear is rotatably connected to the top of the U-shaped mounting seat, and the bottom end of the first gear passes through the U-shaped mounting seat and is fixedly connected to the abutment rod.

[0007] Preferably, a motor is provided at the top of the housing near the center, and the output end of the motor passes through the housing and is fixedly connected to the second gear.

A transparent window is provided at the front of the housing 2 to facilitate the user's view of the internal situation. The size of the inlet and outlet troughs 14 is slightly larger than the biodegradable bag, but it will not affect the drying operation. Both the feeding roller 12 and the receiving roller 13 are controlled by a drive source. A temperature sensor can also be installed inside the housing 2 according to actual usage requirements to achieve precise temperature control. The temperature sensor model can be DS18B20. This solution aims to protect the physical structure, but does not protect the circuit and software control. The proposed processing circuit is only to supplement the feasibility and authenticity of this utility model. This utility model does not require protection of the algorithm and circuit technology. It is worth emphasizing that although the electrical control program is not described in detail in this solution, those skilled in the art can be familiar with and apply it based on their professional knowledge.

[0017] Side mounting plates 11 are symmetrically fixedly connected to both ends of the base 1.

[0018] By adopting the above technical solution, the side mounting plate 11 is set to support the installation of the feeding component and the receiving component.

[0019] One of the side mounting plates 11 has a feeding roller 12 at its top, and the other side mounting plate 11 has a receiving roller 13 at its top.

[0020] By adopting the above technical solution, the feeding roller 12 can assist in conveying the printed biodegradable bag into the machine housing 2, and the receiving roller 13 can assist in conveying the dried biodegradable bag to the winding point.

[0021] A second gear 38 is rotatably connected at the top of the casing 2 near the center, and the second gear 38 is located at the center of the two U-shaped mounting bases 34.

[0022] By adopting the above technical solution and setting the second gear 38, the two meshing first gears 37 can be driven to rotate simultaneously during operation.

[0023] The top of the U-shaped mounting base 34 is rotatably connected to a first gear 37 that meshes with the second gear 38, and the bottom end of the first gear 37 passes through the U-shaped mounting base 34 and is fixedly connected to the abutment rod 35.

[0024] By adopting the above technical solution, after the first gear 37 rotates under the action of the motor 21, the two meshing second gears 38 can rotate.

[0025] A motor 21 is located near the center of the top of the housing 2. The output end of the motor 21 passes through the housing 2 and is fixedly connected to the second gear 38.

[0026] By adopting the above technical solution, the working motor 21 is started, thereby causing the fixedly connected second gear 38 to rotate. A protective cover can also be set on the outside of the motor 21 according to actual usage requirements. In addition, a ventilation hole is opened at the top of the housing 2.

[0027] A hot air blower body 24 is provided on the side wall of the casing 2 near the top. Two air ducts 25 are fixedly connected to the bottom of the hot air blower body 24, and the other end of the air ducts 25 is fixedly connected to the air nozzle 23.

[0028] By adopting the above technical solution, after the hot air blower body 24 is working, the hot air can be discharged outward through the nozzle 23 under the action of the air duct 25. The hot air blower body 24 can be installed in the protective shell, and the protective shell can be installed inside the side end of the casing 2, and is provided with ventilation holes and wiring harness holes, thereby avoiding damage to the hot air blower body 24.

[0029] Working principle: When using this device, first place the equipment near the biodegradable bag water-based ink printing equipment. Then, after the printed biodegradable bag moves a certain distance, it enters the machine housing 2 with the assistance of the feeding roller 12 (the certain distance is to allow the large area of ​​water-based ink on the biodegradable bag to drip off, so that the drying effect and the equipment will not be affected when the biodegradable bag is dried). Before the biodegradable bag enters the machine housing 2, the hot air blower body 24 needs to be turned on so that the machine housing 2 is filled with hot air (heat) in advance. After the biodegradable bag enters the machine housing 2, with the cooperation of two sets of air nozzles 23, hot air is blown on both sides of the biodegradable bag at the same time for drying, so that different positions on both sides of the biodegradable bag can get the same drying effect. In addition, the position of the spray nozzles 23 can be adjusted according to the width of the biodegradable bag and the degree of printing. By starting the working motor 21, the fixedly connected second gear 38 is rotated, which causes the two meshing first gears 37 to rotate simultaneously. This drives the two push rods 35 to move towards each other. Then, under the action of the auxiliary wheel 36, the guide shaft 31 and the tension spring 32, the two spray nozzles 23 move towards each other (the air duct 25 is telescopic to facilitate the adjustment of the spray nozzles 23), thereby achieving the effect of synchronous adjustment of the two sets of spray nozzles 23, thus improving the practicality of the equipment during use.
