Description

Technical Field

[0001] This utility model relates to the field of packaging bag drying technology, specifically, to a drying device for packaging bag printing. Background Technology

[0002] During the printing process of packaging bags, the printed ink or paint needs to dry quickly to fix the pattern and color, prevent quality problems such as color bleeding and blurring, and ensure the clarity and durability of the printing effect. Traditional drying methods, such as natural air drying, are not only slow and will greatly extend the production cycle and reduce production efficiency, but are also easily affected by the ambient temperature and humidity. In a humid environment, the drying time will be significantly extended, and may even lead to problems such as ink not drying or sticking.

[0003] In the prior art, during the drying process of packaging bags, the contact surface between the packaging bag and the ink is relatively moist. When drying paper packaging bags, wrinkles and unevenness are prone to occur on the contact surface. If pressure is not applied to the surface of the packaging bag in time, it will not only damage the flatness of the packaging bag surface, but also cause the printed pattern to be distorted and deformed. The originally clear and exquisite pattern becomes blurry and difficult to distinguish, which seriously affects the appearance of the product. Therefore, those skilled in the art provide a drying device for printing packaging bags to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for printing packaging bags, thereby solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a drying device for printing packaging bags, including a workbench body and a packaging bag body. A conveyor belt body is installed on the upper top of the workbench body. A drying box is fixedly connected to the upper top edge of the conveyor belt body. An interval mechanism for controlling the distance between two packaging bag bodies is provided on one side of the upper top of the conveyor belt body located in the drying box. Several packaging bag bodies are placed on the moving end surface of the conveyor belt body. A drying mechanism for drying the packaging bag bodies is provided inside the drying box.

[0006] Preferably, an exhaust fan for discharging air from inside the drying chamber is fixedly connected to the center of the top of the drying chamber, an exhaust hood is fixedly connected to the exhaust end of the exhaust fan, and an exhaust flange pipe connected to an external pipeline is fixedly connected to the top of the exhaust hood.

[0007] Preferably, the drying mechanism includes a drive motor fixedly connected to the outer wall of the drying chamber, a drive rod fixedly connected to the output end of the drive motor, two auxiliary frames symmetrically arranged inside the drying chamber, the centers of the two auxiliary frames being fixedly connected to the outer wall of the drive rod, and the end of the drive rod away from the drive motor being rotatably sleeved with the inner wall of the drying chamber through a bearing.

[0008] Preferably, an electric heating dryer is fixedly connected to one side of the two auxiliary frames that are close to each other, and a magnetic suction plate is rotatably sleeved on one side of the two auxiliary frames that are close to each other, with the magnetic suction plate located on the side away from the electric heating dryer.

[0009] Preferably, the magnetic suction plate has two second fixed supports symmetrically fixedly connected to its upper top, and the drying box has two third fixed supports symmetrically fixedly connected to its inner sidewall. A second electric push rod is provided between each of the second and third fixed supports. The telescopic end and the end of the second electric push rod are respectively rotatably connected to the interior of the second and third fixed supports. An electromagnet for magnetically absorbing the magnetic suction plate is provided inside the conveyor belt body.

[0010] Preferably, the spacing mechanism includes two auxiliary plates symmetrically fixedly connected to the outer wall of the drying chamber. Each auxiliary plate has a first electric push rod fixedly connected to its upper top. Each first electric push rod has a connecting frame fixedly connected to its telescopic end. The ends of the two connecting frames are fixedly connected to a vertical plate. The bottom end of the vertical plate is fixedly connected to a spacing frame for controlling the distance between the two packaging bag bodies. The outer wall of the workbench body is provided with a cleaning mechanism for removing paper scraps from the surface of the conveyor belt body.

[0011] Preferably, the cleaning mechanism includes two first fixed brackets symmetrically fixedly connected to the outer side wall of the workbench body, and the two first fixed brackets are internally damped and connected to scrapers, the cleaning end of the scraper contacting the bottom surface of the conveyor belt body.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention incorporates a drying mechanism. Due to the spacing mechanism, each packaging bag body is spaced evenly. During the drying process, an electric dryer dries the printed material on the surface of the packaging bag body. The conveyor belt pauses briefly to allow the printed surface to dry fully. When the dried packaging bag body moves directly under the magnetic plate, the electromagnet activates and attracts the magnetic plate. The packaging bag body, positioned between the two, is then flattened. The flattening time is the same as the pause time of the conveyor belt. Since the magnetic plate is driven by the auxiliary frame and drive rod, both are simultaneously in operation (as shown in the conveyor belt diagram, the electric dryer is parallel, the magnetic plate approaches the electromagnet under the drive of the auxiliary frame, and the electromagnet attracts the magnetic plate, applying pressure to the packaging bag body). Furthermore, after the auxiliary frame and drive rod rotate into position, the bottom end of the magnetic plate contacts the surface of the packaging bag body. The attraction of the magnetic plate by the electromagnet increases the pressure exerted by the magnetic plate on the packaging bag body. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Please see Figures 1-4As shown, this utility model provides a technical solution: a drying device for printing packaging bags, including a workbench body 1 and a packaging bag body 3. A conveyor belt body 2 is installed on the upper top of the workbench body 1. A drying box 4 is fixedly connected to the upper top edge of the conveyor belt body 2. An interval mechanism 5 for controlling the distance between two packaging bag bodies 3 is provided on one side of the upper top of the conveyor belt body 2 located in the drying box 4. Several packaging bag bodies 3 are placed on the moving end surface of the conveyor belt body 2. A drying mechanism 10 for drying the packaging bag bodies 3 is provided inside the drying box 4.

[0017] It should be noted that the main body 1 of the workbench serves as a supporting base, and the conveyor belt 2 installed on it can stably transport the packaging bag body 3. The drying chamber 4 at the top edge of the conveyor belt 2 can dry the passing packaging bag body 3. The spacing mechanism 5 is set at the top of the conveyor belt 2 and is located on one side of the drying chamber 4. It can precisely control the spacing between two packaging bag bodies 3, ensuring that each packaging bag body 3 can receive uniform and sufficient drying treatment, avoiding uneven drying due to too small a spacing or wasted space due to too large a spacing. The drying mechanism 10 is located inside the drying chamber 4, which can quickly and effectively remove moisture from the surface of the packaging bag body 3, greatly shortening the drying time and improving production efficiency.

[0018] As one implementation method in this embodiment, please refer to Figure 1 As shown, an exhaust fan 6 for discharging air from inside the drying chamber 4 is fixedly connected to the center of the top of the drying chamber 4. An exhaust hood 7 is fixedly connected to the exhaust end of the exhaust fan 6. An exhaust flange pipe 8 connected to an external pipe is fixedly connected to the top of the exhaust hood 7.

[0019] It should be noted that the exhaust fan 6 located at the top center of the drying chamber 4 can quickly remove odors generated inside the drying chamber 4 by the drying packaging bag body 3, preventing unpleasant odors from accumulating inside the drying chamber 4. The exhaust hood 7 is fixed to the exhaust end of the exhaust fan 6, which can guide the exhaust air in an orderly manner, making the air exit more smoothly, reducing air turbulence and energy loss during exhaust, and further improving the exhaust effect. The exhaust flange pipe 8 is connected to the top of the exhaust hood 7 and connected to the external pipeline. This design facilitates the introduction of exhaust air into the designated treatment or emission area. According to actual production needs, the gas can be guided to a suitable purification or emission device to avoid adverse effects on the working environment. At the same time, the flange connection method ensures the stability and sealing of the connection, prevents air leakage, and ensures the efficient and reliable operation of the exhaust system.

[0020] As one implementation method in this embodiment, please refer to Figure 2 and Figure 3As shown, the drying mechanism 10 includes a drive motor 101 fixedly connected to the outer wall of the drying chamber 4. The output end of the drive motor 101 is fixedly connected to a drive rod 102. Two auxiliary frames 103 are symmetrically arranged inside the drying chamber 4. The center of the two auxiliary frames 103 is fixedly connected to the outer wall of the drive rod 102. The end of the drive rod 102 away from the drive motor 101 is rotatably sleeved with the inner wall of the drying chamber 4 through a bearing. An electric heating dryer 104 is fixedly connected to the side of the two auxiliary frames 103 that is close to each other. A magnetic suction plate 105 is rotatably sleeved on the side of the two auxiliary frames 103 that is close to each other. The magnetic suction plate 105 is located on the side away from the electric heating dryer 104.

[0021] It should be noted that the two auxiliary frames 103 are symmetrically arranged inside the drying chamber 4 and connected to the drive rod 102. They can rotate synchronously with the drive rod 102 to ensure structural stability and make the drying operation more precise. The electric heating dryer 104 is fixed on the side of the two auxiliary frames 103 that are close to each other. It can evenly and efficiently dissipate heat to thoroughly dry the main body of the packaging bag 3, effectively remove its surface moisture, shorten the drying time, improve the drying quality, and avoid problems such as wrinkles and deformation of the packaging bag due to insufficient drying, thus ensuring the printing effect. At the same time, the rotation characteristics of the magnetic suction plate 105 can increase the contact area with the main body of the packaging bag 3 and apply pressure to the main body of the packaging bag 3 to ensure that its surface printing surface is in a flat state.

[0022] As one implementation method in this embodiment, please refer to Figure 2 and Figure 3 As shown, two second fixed brackets 106 are symmetrically fixedly connected to the top end of the magnetic suction plate 105, and two third fixed brackets 107 are symmetrically fixedly connected to the inner side wall of the drying box 4. A second electric push rod 108 is provided between each second fixed bracket 106 and the third fixed bracket 107. The telescopic end and the end of the second electric push rod 108 are rotatably connected to the interior of the second fixed bracket 106 and the third fixed bracket 107, respectively. An electromagnet 109 for magnetically absorbing the magnetic suction plate 105 is provided inside the conveyor belt body 2.

[0023] It should be noted that the two second fixed brackets 106 symmetrically arranged at the top of the magnetic suction plate 105 and the two third fixed brackets 107 symmetrically arranged on the inner side wall of the drying chamber 4 are connected by the second electric push rod 108. The second electric push rod 108 can be flexibly extended and retracted, and can accurately adjust the distance between the magnetic suction plate 105 and the packaging bag body 3. Through this operation, the magnetic suction plate 105 and the conveyor belt body 2 can be kept in a parallel state. When drying the packaging bag body 3, the magnetic suction plate 105 will contact the packaging bag body 3 and apply pressure to the packaging bag body 3, so that the surface of the packaging bag body 3 is relatively flat and wrinkles are avoided. The electromagnet 109 is fixedly connected to the connecting frame of the conveyor belt body 2.

[0024] As one implementation method in this embodiment, please refer to Figure 2 and Figure 4 As shown, the spacing mechanism 5 includes two auxiliary plates 51 symmetrically fixedly connected to the outer wall of the drying oven 4. Each auxiliary plate 51 has a first electric push rod 52 fixedly connected to its upper top. Each first electric push rod 52 has a connecting frame 53 fixedly connected to its telescopic end. The ends of the two connecting frames 53 are fixedly connected to a vertical plate 54. The bottom end of the vertical plate 54 is fixedly connected to a spacer 55 for controlling the distance between the two packaging bag bodies 3. The outer wall of the workbench body 1 is provided with a cleaning mechanism 9 for removing paper scraps from the surface of the conveyor belt body 2. The cleaning mechanism 9 includes two first fixed brackets 91 symmetrically fixedly connected to the outer wall of the workbench body 1. The two first fixed brackets 91 are internally damped and connected to a scraper 92. The cleaning end of the scraper 92 contacts the bottom surface of the conveyor belt body 2.

[0025] It should be noted that by moving the vertical plate 54 and the spacer 55 via the connecting frame 53, the spacing between two packaging bag bodies 3 can be flexibly adjusted according to the needs of different specifications of packaging bag bodies 3. This ensures that each packaging bag body 3 can receive uniform and sufficient drying treatment, avoiding uneven drying due to improper spacing, and improving drying quality and efficiency. In the cleaning mechanism 9, two first fixed brackets 91 are symmetrically fixed to the outer wall of the workbench body 1, and the scraper 92 is damped and connected therein. This design ensures that the scraper 92 is in close contact with the bottom surface of the conveyor belt body 2. During the operation of the conveyor belt body 2, the scraper... The scraper 92 can effectively remove paper scraps and other debris attached to its surface, preventing debris from entering the drying chamber 4 and affecting the drying effect, or from mixing into the packaging bag body 3 and reducing product quality. Moreover, the damping connection method facilitates the installation, disassembly and replacement of the scraper 92. The position and angle of the scraper 92 can be adjusted in a timely manner according to the actual use to ensure the cleaning effect. When the conveyor belt body 2 stops each time, one packaging bag body 3 is brought into contact with the edge of the spacer 55. Then, the first electric push rod 52 is controlled to drive the spacer 55 to rise. When the conveyor belt body 2 stops again, this operation is repeated to complete the spacing adjustment between the packaging bag bodies 3.

[0026] Working principle: By setting the drying mechanism 10 and the spacing mechanism 5 to work together, efficient drying and flattening are achieved. During operation, the spacing mechanism 5 drives the vertical plate 54 and the spacing frame 55 to press down through the first electric push rod 52, accurately controlling the spacing between adjacent packaging bag bodies 3 on the conveyor belt body 2, and ensuring that the spacing between each packaging bag body 3 is the same. When the main body of the packaging bag 3 enters the drying chamber 4, the main body of the conveyor belt 2 stops for a moment. At this time, the drive motor 101 of the drying mechanism 10 drives the drive rod 102 to rotate. The drive rod 102 rotates the electric heating dryer 104 and the magnetic suction plate 105 synchronously through the auxiliary frame 103, so that the electric heating dryer 104 is aligned parallel to the printed material on the surface of the main body of the packaging bag 3 for thorough drying. After drying is completed, the main body of the conveyor belt 2 continues to run. When the main body of the packaging bag 3 moves directly under the magnetic suction plate 105, the electromagnet 109 starts to attract the magnetic suction plate 105. At this time, the main body of the packaging bag 3 is clamped between the magnetic suction plate 105 and the main body of the conveyor belt 2. The second electric push rod 108 adjusts the angle of the magnetic suction plate 105 through the linkage of the second fixed bracket 106 and the third fixed bracket 107 to ensure that its bottom end is in complete contact with the surface of the main body of the packaging bag 3. The flattening effect is enhanced by the attraction of the electromagnet 109. The flattening time is synchronized with the resting time of the main body of the conveyor belt 2. Meanwhile, the exhaust fan 6 continuously exhausts the odor generated during drying in the drying chamber 4 through the exhaust hood 7 and the exhaust flange pipe 8, improving drying efficiency. The cleaning mechanism 9E scraper 92 scrapes off the surface paper scraps when the conveyor belt body 2 returns, keeping the equipment clean. This design, through the combined effect of electric heating drying and mechanical flattening, combined with precise spacing control and dynamic pressure adjustment, significantly improves the drying quality and surface flatness of the printed material on the packaging bag body 3.

[0027] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
