Technical Field
[0001] This utility model relates to the field of printing device technology, specifically a printing device for wood ear mushroom packaging bags. Background Technology
[0002] Black fungus, also known as cloud ear or mulberry ear, is an important edible fungus in my country, with a wide natural distribution and artificial cultivation. It has a soft texture, delicate taste, and delicious flavor, and is rich in protein, fat, carbohydrates, and various vitamins and minerals, making it highly nutritious. Modern nutritionists praise it as "the meat of the vegetarian world." The nutritional value of black fungus is comparable to that of animal-based foods, with extremely high levels of iron and vitamin K.
[0003] After being dried, wood ear mushrooms need to be packaged in bags before being sold. The bags need to be printed with relevant information, such as the variety, grade, and manufacturer of the wood ear mushrooms. However, the existing wood ear mushroom packaging bag printing devices are prone to problems when printing. Because the packaging bags are very light, they are easily displaced by slight airflow disturbances when placed flat on the worktable. Furthermore, the packaging bags are prone to wrinkles when placed, making it difficult to ensure sufficient flatness. This can easily lead to a decline in printing quality, resulting in problems such as unclear or skewed printing.
[0004] Therefore, there is a need for a printing device for wood ear mushroom packaging bags that can fix the packaging bags and ensure their flatness. Utility Model Content
[0005] To address the aforementioned issues, this invention proposes a printing device for wood ear mushroom packaging bags, which can lay the packaging bags flat, ensuring a smooth printing process and improving printing quality.
[0006] To achieve the above objectives, the present invention proposes the following specific solutions:
[0007] A printing device for mushroom packaging bags includes a workbench, a support plate fixed to the top edge of the workbench, a top plate fixed to the top of the support plate, a hydraulic device fixed to the bottom edge of the top plate, a fixing plate fixed to the lower end of the hydraulic device, a printer fixed to the center of the bottom surface of the fixing plate, a support frame symmetrically fixed to the top surface of the workbench, the support frame located on both sides of the printer, a rectangular hole in the center of the top surface of the support frame, a vertical plate movably inserted into the inner side of the rectangular hole, the vertical plate passing through the rectangular hole, an insertion groove in the center of the bottom surface of the vertical plate, a spring fixed to the top surface of the inner side of the insertion groove, and the vertical plate... A roller box is provided below, located inside the support frame. A plug-in block is fixed in the middle of the top surface of the roller box. The plug-in block is movably inserted into the inside of the plug-in slot. The plug-in block is fixedly connected to a spring. A second fixed shaft is fixed on the inner wall of the roller box. A second roller is movably sleeved on the outside of the second fixed shaft. A connecting hole is provided in the middle of the top surface of the vertical plate. A fixed frame is fixed on the top surface of the support frame. A threaded hole is provided on the top surface of the fixed frame. A screw is threadedly connected to the inside of the threaded hole. The screw passes through the threaded hole. A connecting rod is fixed to the lower end of the screw. The connecting rod is movably inserted into the inside of the connecting hole.
[0008] As a preferred technical solution of the printing device for wood ear packaging bags of this utility model, the side wall of the fixing plate is symmetrically fixed with an arc plate, and one end of the arc plate is provided with a rolling groove.
[0009] As a preferred technical solution of the printing device for wood ear packaging bags of this utility model, a first fixed shaft is fixed to the inner wall of the rolling groove, and a first roller is movably sleeved on the outer side of the first fixed shaft.
[0010] As a preferred technical solution of the printing device for wood ear packaging bags of this utility model, a limiting groove is provided at the lower end of the connecting hole, and the limiting groove is in communication with the connecting hole.
[0011] As a preferred technical solution of the printing device for wood ear packaging bags of this utility model, the lower end of the connecting rod is fixed with a limiting plate, and the limiting plate is movably sleeved inside the limiting groove.
[0012] As a preferred technical solution of the printing device for wood ear packaging bags of this utility model, the bottom edge of the workbench is fixed with support legs.
[0013] As a preferred technical solution of the printing device for wood ear packaging bags of this utility model, the support legs are provided in multiple ways, and the arc plate is made of elastic material.
[0014] As a preferred technical solution of the printing device for wood ear packaging bags according to this utility model, the size of the limiting plate is adapted to the size of the limiting groove.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] In this invention, during printing, the packaging bag can be laid flat in the middle of the workbench. Two second rollers press down on both ends of the packaging bag to fix it and keep it flat. By rotating the screw, the screw moves downward in the threaded hole, causing the vertical plate to move downward, applying pressure to the spring and increasing its elasticity. This increases the pressure exerted by the spring on the roller box through the insert block, ultimately resulting in greater pressure exerted by the second rollers on the packaging bag. Conversely, reversing the screw reduces the pressure exerted by the second rollers on the packaging bag. This adjustment can be made according to the actual situation during the printing process. In this process, the hydraulic equipment drives the fixed plate to move downwards, which in turn moves the printer downwards to print on the packaging bag. The two first rollers on both sides of the fixed plate first come into contact with the packaging bag, and the downward pressure causes the elastic material arc plate to deform. The two first rollers roll on both sides of the packaging bag, flattening the bag again and further ensuring its flatness. After printing, the packaging bag is pulled to one side, which causes the second roller to roll and remove the packaging bag. This solution is simple and convenient to operate, and can ensure the stability and flatness of the packaging bag during the printing process, thus guaranteeing the printing quality.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1
[0027] Please see Figure 1-7 As shown, the present invention provides the following technical solution: a printing device for wood ear mushroom packaging bags, including a workbench 1, with a support leg 11 fixed to the bottom edge of the workbench 1. Multiple support legs 11 are provided, which can support the workbench 1 and raise the height of the workbench 1 for convenient operation.
[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, specifically, a support frame 2 is symmetrically fixed on the top surface of the workbench 1 to support the fixed frame 21. The support frame 2 is located on both sides of the printer 15. A rectangular hole 23 is provided in the middle of the top surface of the support frame 2 for the vertical movement of the vertical plate 24. The vertical plate 24 is movably inserted into the inner side of the rectangular hole 23, which can drive the roller box 25 to move up and down. The vertical plate 24 passes through the rectangular hole 23. A insertion groove 243 is provided in the middle of the bottom surface of the vertical plate 24 for connecting the insertion block 251 and the spring 244. The spring 244 is fixed on the top surface of the inner side of the insertion groove 243. The spring 244 can apply pressure to the second roller 253 without completely restricting the movement of the packaging bag. A roller box 25 is provided below the vertical plate 24 for holding... The second roller 253 is housed and pressure is applied to it. The roller box 25 is located inside the support frame 2. A plug-in block 251 is fixed in the middle of the top surface of the roller box 25 to transmit the pressure of the spring 244 to the roller box 25. The plug-in block 251 is movably inserted into the inside of the plug-in slot 243 and is fixedly connected to the spring 244. A second fixed shaft 252 is fixed to the inner wall of the roller box 25 for connecting the second roller 253. The second roller 253 is movably sleeved on the outside of the second fixed shaft 252 to press down the packaging bag and allow the packaging bag to move by rolling. A connecting hole 241 is provided in the middle of the top surface of the vertical plate 24 for connecting the connecting rod 221. A limiting groove 242 is provided at the lower end of the connecting hole 241. The movement of the limiting plate 222 is restricted, but the limiting plate 222 can rotate. The limiting groove 242 is in communication with the connecting hole 241. A fixing frame 21 is fixed on the top surface of the support frame 2 to support the screw 22. The top surface of the fixing frame 21 is provided with a threaded hole 211 for connecting the screw 22. The screw 22 is threadedly connected to the inner side of the threaded hole 211. By rotating the screw 22, the vertical plate 24 can be driven to move. The screw 22 passes through the threaded hole 211. A connecting rod 221 is fixed at the lower end of the screw 22 for connecting and fixing the limiting plate 222. The connecting rod 221 is movably inserted into the inner side of the connecting hole 241. The limiting plate 222 is fixed at the lower end of the connecting rod 221, so that the screw 22 can smoothly drive the vertical plate 24 to move. The movable sleeve is fitted inside the limiting groove 242. The size of the limiting plate 222 is adapted to the size of the limiting groove 242. This solution uses two second rollers 253 to press down both ends of the packaging bag. When the packaging bag is laid flat on the worktable 1, it maintains the stability and flatness of the packaging bag. By rotating the screw 22 in both directions, the screw 22 can drive the vertical plate 24 to move up and down, changing the pressure applied by the vertical plate 24 to the spring 244. Adjusting the elasticity of the spring 244 changes the pressure applied by the spring 244 to the roller box 25 through the plug block 251, thereby adjusting the pressure of the second roller 253 pressing down on the packaging bag. This adapts to the needs of different thicknesses of the packaging bag, improving the quality of the printing work. Example 2
[0029] In another embodiment of this solution, refer to Figure 1 , Figure 2 and Figure 7 As shown, specifically, a support plate 12 is fixed to the top edge of the workbench 1 to support the top plate 121. The top plate 121 is fixed to the top of the support plate 12 to fix the hydraulic device 13. The hydraulic device 13 (which is existing technology, and its specific operation and principle can be referred to in the existing technology of electric hydraulic cylinders, which are controlled by an external power source, so it is not described in detail here) is fixed to the lower end of the hydraulic device 13 with a fixing plate 131 to fix the printer 15 and the arc plate 14. The printer 15 (which is existing technology, and its specific operation and principle can be referred to in the existing technology of heat transfer printing equipment, which can print on packaging bags, so it is not described in detail here) is fixed to the middle of the bottom surface of the fixing plate 131. The arc plate 14 is symmetrically fixed to the side wall of the fixing plate 131. The curved plate 14 is made of elastic material and can deform under pressure. One end of the curved plate 14 is provided with a rolling groove 141 to provide space for the first roller 143 to roll. The inner wall of the rolling groove 141 is fixed with a first fixed shaft 142 to connect the first roller 143. The first roller 143 is movably sleeved on the outer side of the first fixed shaft 142, which can help flatten the packaging bag. In this solution, the fixed plate 131 is driven to move down by the hydraulic device 13. The fixed plate 131 drives the printer 15 to move down to print on the packaging bag on the worktable 1. When the printer 15 moves down, the first rollers 143 on both sides first contact the packaging bag. As the curved plate 14 deforms under pressure, the two first rollers 143 roll on both sides of the packaging bag to flatten it, ensuring the flatness of the packaging bag during printing and improving the printing effect.
[0030] The working principle and usage process of this utility model:
[0031] When in use, the packaging bag is laid flat in the middle of the workbench 1. The two second rollers 253 press down on both ends of the packaging bag to stabilize it and keep it flat. For packaging bags of different thicknesses, the screw 22 can be rotated to rise or fall inside the threaded hole 211, which in turn drives the vertical plate 24 to rise or fall. This can adjust the pressure applied by the vertical plate 24 to the spring 244, change the elastic force of the spring 244, and thus change the pressure applied by the spring 244 to the roller box 25 through the plug block 251. This adjusts the pressure of the second roller 253 on the packaging bag to adapt to different situations.
[0032] After the packaging bag is secured, the hydraulic device 13 is started. The hydraulic device 13 drives the fixing plate 131 to move down. The fixing plate 131 drives the printer 15 to move down. When the printer 15 moves down, the first rollers 143 on both sides will first contact the packaging bag. As the two elastic material arc plates 14 are deformed by pressure, the two first rollers 143 roll to both sides to flatten the packaging bag again. Then the printer 15 contacts the packaging bag to print words.
[0033] After printing is completed, the hydraulic device 13 drives the printer 15 to rise, and then pulls the packaging bag from one end. As the two second rollers 253 roll, the packaging bag moves to one side, and the packaging bag can be pulled out.
[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
