Abstract
Description
Technical Field
[0001] This utility model relates to the field of foaming machine technology, specifically to a foaming machine for packaging box production. Background Technology
[0002] In the packaging box manufacturing industry, foamed materials are widely used in the production of various packaging boxes due to their excellent cushioning, heat insulation, and moisture-proof properties, protecting products from damage during transportation and storage. As a key piece of equipment in the production of foamed materials, the performance and quality of the foaming machine directly affect the quality of the packaging boxes and production efficiency.
[0003] Traditional foaming machines have several shortcomings in structure and function. Firstly, their mixing structure is relatively simple, with the foaming rod typically fixed. This makes it difficult to thoroughly and evenly mix materials in different locations within the foaming tank, resulting in poor foaming performance and uneven bubble size and distribution, thus affecting the cushioning performance of the packaging box. Secondly, foaming material easily adheres to the inner wall of the foaming tank, making cleaning difficult. This not only wastes material but also affects the quality and efficiency of subsequent foaming operations, and long-term accumulation may damage the equipment. Furthermore, the discharge control methods of traditional foaming machines are outdated, often relying on manual operation of the discharge baffle. This is inconvenient and makes it difficult to accurately control the discharge volume and timing, affecting the continuity and stability of production. Therefore, we propose a foaming machine for packaging box production. Utility Model Content
[0004] The purpose of this invention is to provide a foaming machine for packaging box production, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a mounting frame, a base plate fixedly mounted at the bottom of the mounting frame, and several support plates evenly fixedly mounted on the side wall of the mounting frame. The bottom of the support plates is fixedly connected to the base plate. A fixing rod is also fixedly mounted at the top of the mounting frame. A foaming tank is mounted on one side of the bottom of the fixing rod via a mounting plate. A stirring shaft is rotatably mounted on the fixing rod via a bearing, extending into the interior of the foaming tank. Several foaming rods are evenly fixedly mounted on the stirring shaft inside the foaming tank. A discharge pipe is also provided at the bottom of the foaming tank. A support plate is fixedly mounted on the outer side of the discharge pipe. A rotating shaft is rotatably mounted on the support plate via a bearing. A discharge baffle is fixedly mounted on the rotating shaft, and a discharge port is provided on the discharge baffle.
[0006] Preferably, a limiting plate is fixedly installed at the outer end of the foaming rod, a sleeve is slidably sleeved on the outer side of the limiting plate, a scraper is fixedly installed on the outer wall of the sleeve, and the side wall of the scraper contacts the inner wall of the foaming barrel.
[0007] Preferably, a second motor is fixedly mounted on the support plate, and a driving gear is connected to the power output shaft of the second motor via a key. A driven gear is connected to the rotating shaft via a key, and the driven gear meshes with the driving gear.
[0008] Preferably, a return spring is also provided inside the sleeve, with one end of the return spring fixedly connected to the limiting plate and the other end of the return spring fixedly connected to the inner wall of the sleeve.
[0009] Preferably, a fixing frame is fixedly installed on the top of the fixing rod, and a drive shaft is rotatably mounted on the fixing frame via a bearing. A first synchronous pulley is connected to the stirring shaft via a key, and a second synchronous pulley is connected to the drive shaft via a key. The second synchronous pulley is connected to the first synchronous pulley via a synchronous belt.
[0010] Preferably, a first motor is also fixedly installed on the top of the fixing frame, and the power output shaft of the first motor is fixedly connected to the drive shaft through a coupling.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the first motor drives the drive shaft to rotate, and the synchronous pulley and synchronous belt drive the stirring shaft to rotate the foaming rod inside the foaming tank. This design can achieve full stirring of the foaming material, making the bubble size and distribution more uniform, effectively improving the foaming effect, thereby enhancing the cushioning performance of the packaging box and better protecting the product. At the same time, the combination of the limiting plate, sleeve, scraper and return spring set at the outer end of the foaming rod plays a role. During the stirring process, the return spring keeps the scraper in close contact with the inner wall of the foaming tank, which can scrape off the foaming material attached to the inner wall in time, avoiding material waste, while ensuring the quality and efficiency of subsequent foaming operations and reducing the risk of equipment damage due to material accumulation.
[0012] In addition, the second motor drives the drive gear to rotate, which in turn drives the rotating shaft and the discharge baffle to rotate through the driven gear meshing with it. By controlling the relative position of the discharge port and the discharge pipe on the discharge baffle, the discharge amount and discharge time can be precisely controlled. The operation is convenient, improves the continuity and stability of production, and meets the requirements of the packaging industry for production efficiency and product quality.

Under the action of the scraper 17, the material adhering to the inner wall of the foaming tank 7 can be scraped off, thereby ensuring the efficiency of the foaming tank 7. A return spring 18 is also provided inside the sleeve 16. One end of the return spring 18 is fixedly connected to the limiting plate 15, and the other end of the return spring 18 is fixedly connected to the inner wall of the sleeve 16. Under the action of the return spring 18, the contact quality between the scraper 17 and the foaming tank 7 is ensured, thereby ensuring the efficiency of the scraper 17.
[0021] The bottom of the foaming tank 7 is also equipped with a discharge pipe 19. A support plate 20 is fixedly installed on the outside of the discharge pipe 19. A rotating shaft 21 is rotated on the support plate 20 through a bearing. A discharge baffle 22 is fixedly installed on the rotating shaft 21. A discharge port 23 is opened on the discharge baffle 22. At this time, under the action of the discharge baffle 22, the discharge pipe 19 can be sealed.

[0024] Working principle: When the foaming device is working, the foaming material is first placed in the foaming tank 7. The first motor 13 is started, and its power output shaft drives the drive shaft 10 to rotate through the coupling. The second synchronous pulley 11 on the drive shaft 10 drives the first synchronous pulley 9 to rotate through the synchronous belt 12. The first synchronous pulley 9 drives the stirring shaft 8 to rotate on the bearing of the fixed rod 4. The foaming rod 14 on the stirring shaft 8 rotates accordingly, stirring the material in the foaming tank 7 to ensure foaming efficiency. On the limiting plate 15 at the outer end of the foaming rod 14, one end of the return spring 18 is fixedly connected to the limiting plate 15, and the other end is fixedly connected to the inner wall of the sleeve 16. Under the action of the return spring 18, the scraper 17 on the outer wall of the sleeve 16 is always in close contact with the inner wall of the foaming tank 7, scraping off the material adhering to the inner wall and ensuring the utilization efficiency of the foaming tank 7. After foaming is completed, the second motor 26 is started. Its power output shaft drives the drive gear 25 to rotate, which in turn drives the driven gear 24 to rotate. The driven gear 24 drives the rotating shaft 21 to rotate on the bearing of the support plate 20. The rotating shaft 21 drives the discharge baffle 22 to rotate. When the discharge port 23 on the discharge baffle 22 is aligned with the discharge pipe 19, the foaming material is discharged from the discharge pipe 19, realizing the discharge function. In the entire device, the mounting frame 1 ensures stability through the base plate 2 and the support plate 3, and the fixing rod 4 provides the mounting foundation for each component, ensuring stable operation of the device.
