Description

Technical Field

[0001] The utility model relates to the technical field of fiberboard production, in particular to an environmentally friendly fiberboard glue mixing device. Background Art

[0002] In the existing fiberboard production process, glue mixing is a crucial link, which is directly related to the final performance and quality of the fiberboard. The traditional method is often to add various additives and glue to the fiber raw materials by simple pouring or manual mixing, which has many shortcomings. First of all, due to the wide variety of additives and glues, and their different physical and chemical properties, a simple pouring method is difficult to ensure that the various ingredients are fully and evenly mixed. At the same time, it takes a certain amount of time to disperse the aggregated additives and glues, which greatly reduces the mixing efficiency. Secondly, traditional stirring equipment can often only achieve simple rotary stirring. For the raw materials at the bottom of the mixing tank, they are easy to sink to the bottom due to gravity, forming a mixing blind spot, resulting in the inability of the bottom raw materials to be fully mixed with other raw materials, affecting the overall quality of the fiberboard. Although some equipment has an anti-sinking design, most of them are relatively complex in structure, high in cost, and not flexible in use. Utility Model Content

[0003] In response to the shortcomings of the existing technology, the utility model provides an environmentally friendly fiberboard glue mixing device, which has the advantages of pre-mixing glue and additives and uniform feeding, solving the problem of increased mixing time caused by the direct pouring feeding method.

[0004] The utility model provides the following technical solutions: an environmentally friendly fiberboard glue mixing device, comprising a stirring kettle, a stirring shaft rotatably installed in the middle of the interior of the stirring kettle, a pretreatment box fixedly installed at the right position of the upper end of the stirring kettle, a transmission shaft rotatably installed in the middle of the interior of the pretreatment box, and evenly distributed stirring rods are fixedly sleeved on the outer side of the transmission shaft, a switch roller rotatably installed in the middle of the lower end of the pretreatment box inside the stirring kettle, a feeding trough is provided in the middle of the switch roller, the right end of the switch roller passes through the stirring kettle and is fixedly connected to a crank, a spreading plate is fixedly installed in the interior of the stirring kettle near the lower end opening of the pretreatment box, the stirring shaft passes through the spreading plate and is fixedly sleeved with a scraper, and the lower end of the scraper is in contact with the spreading plate.

[0005] Furthermore, a slave bevel gear is fixedly sleeved on the left end of the transmission shaft, and a main bevel gear is fixedly sleeved on the outer side of the stirring shaft near the upper side, and the main bevel gear and the slave bevel gear are meshedly connected.

[0006] Furthermore, the front and rear inner walls of the pretreatment box are fixedly connected with guide plates, and the lower ends of the guide plates are in contact with the switch rollers.

[0007] Furthermore, the upper end of the stirring kettle is fixedly connected to a fixing frame, the upper end of the fixing frame is fixedly installed with a reduction motor, and the output end of the reduction motor and the upper end of the stirring shaft are fixedly connected via a coupling.

[0008] Furthermore, a spiral rod is fixedly connected to the lower end of the stirring shaft, and a discharge pipe is provided in the middle of the lower end of the stirring kettle, and the lower end of the spiral rod extends to the inside of the discharge pipe and fits therewith.

[0009] Furthermore, a rotating frame is fixedly sleeved on the outer side of the spiral rod near the lower end, and the rotating frame is fixedly connected to the discharge pipe. A fiber feed port is provided at the left end of the stirring kettle near the lower side of the spreading plate.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. This device achieves full pre-mixing of additives and glue, ensuring uniform mixing. Subsequently, the evenly mixed glue falls onto the spreading plate by rotating the switch roller and is further spread by the scraper, making the glue more evenly distributed in the fiber. This mixing method starting from the source not only reduces preparation time, but also greatly improves stirring efficiency, making the mixing of fiberboard raw materials more thorough and uniform, thereby improving the overall performance and quality of the fiberboard.

[0012] 2. During the stirring process, the stirring shaft is not only responsible for stirring the fiber raw materials, but also realizes effective stirring of the raw materials at the bottom of the stirring kettle by driving the rotation of the screw rod. When the screw rod rotates clockwise, it can use the interaction force between the raw materials to flip the bottom raw materials upwards, effectively avoiding the problem of uneven mixing caused by the sinking of the raw materials. When rotating counterclockwise, the screw rod is transformed into a screw feeder, which smoothly transports the mixed raw materials to the discharge pipe and drives it to move toward the discharge port to complete the discharge operation. This design not only optimizes the stirring effect, but also simplifies the discharge process, reduces the risk of blockage during the discharge process, and improves production efficiency and stability. It has a simple structure and is flexible to use. BRIEF DESCRIPTION OF THE DRAWINGS

In the manufacturing process of fiberboard, it is necessary to add a variety of additives and glue to ensure the performance and quality of the board, such as waterproofing agent, flame retardant and hardener as well as glue, which is an important component, and mix them with the fiber in a certain proportion. When using this device, various additives and glue can be added into the pretreatment box 3 first. By turning on the reduction motor 14, the stirring shaft 2 is driven to rotate, and the main bevel gear 7 is driven to rotate synchronously by the rotation of the stirring shaft 2. The rotation of the main bevel gear 7 can drive the rotation of the slave bevel gear 6, and the rotation of the slave bevel gear 6 drives the stirring rod 5 to rotate, so that the various additives and glue in the pretreatment box 3 can be stirred and mixed evenly by rotating the stirring rod 5.

When the switch roller 8 rotates to make the discharge chute 9 in a vertical direction, the evenly mixed glue can fall into the upper end of the internal spreading plate 12 of the stirring kettle 1. The spreading plate 12 is provided with evenly distributed through holes to make the glue It drips onto the fiber raw material on the lower side. Furthermore, the rotation of the stirring shaft 2 can drive the scraper 13 to rotate, so that the glue gathered together on the spreading plate 12 can be spread out by the rotation of the scraper 13, and the spread glue is more even when dripping down through the through holes on the spreading plate 12. Compared with the traditional feeding method, this device can pre-mix the additive and glue from the source, and then evenly add the mixed glue to the fiber, and then stir it through the stirring shaft 2. This method not only reduces the preparation time, but also greatly improves the stirring efficiency, making the raw materials mixed more thoroughly and evenly.

[0019] See also Figure 3 The front and rear inner walls of the pretreatment box 3 are fixedly connected with guide plates 11, and the lower ends of the guide plates 11 are in contact with the switch rollers 8. That is, the guide plates 11 can prevent the additives and glue from being in the corners, resulting in incomplete mixing, thereby ensuring the rationality of the structure.

[0020] See also Figure 1-Figure 2The upper end of the stirring kettle 1 is fixedly connected to a fixing frame 15, and a reduction motor 14 is fixedly installed on the upper end of the fixing frame 15.

The lower end of the screw rod 16 extends to the inside of the discharge pipe 17 and fits therewith. The outer side of the screw rod 16 is fixedly sleeved with a rotating frame 18 near the lower end. The rotating frame 18 is fixedly connected to the discharge pipe 17. The left end of the stirring kettle 1 is provided with a fiber feed port 19 near the lower side of the spreading plate 12, which can drive the screw rod 16 when stirring and mixing through the stirring shaft 2. Rotation, by controlling the rotation direction of the stirring shaft 2 driven by the reduction motor 14, the screw rod 16 can achieve different effects, that is, when the screw rod 16 rotates clockwise, it can stir the raw materials at the bottom. At the same time, due to the interaction of forces between the raw materials, the raw materials at the bottom can be flipped upwards, thereby avoiding the bottom raw materials sinking to the bottom and causing uneven mixing. When the screw rod 16 rotates counterclockwise, it fits with the inner wall of the discharge pipe 17, so that it can play the role of a screw feeder, so that the mixed raw materials at the bottom enter the interior of the discharge pipe 17, and drive it to the discharge port to finally complete the discharge operation, while avoiding the risk of blockage during the discharge process. The structure is simple and flexible to use.

[0021] Working principle: When in use, first add various additives and glue into the pretreatment box 3, and turn on the reduction motor 14 to drive the stirring shaft 2 to rotate, and the main bevel gear 7 is driven to rotate synchronously by the rotation of the stirring shaft 2, and the slave bevel gear 6 is driven to rotate by the rotation of the main bevel gear 7, and the stirring rod 5 is driven to rotate by the rotation of the slave bevel gear 6, so that the various additives and glue in the pretreatment box 3 can be stirred and mixed evenly by the rotation of the stirring rod 5, and the switch roller 8 can be driven to rotate by turning the crank 10. When the switch roller 8 is rotated to make the discharge chute 9 in a vertical direction, the evenly mixed glue can fall into the upper end of the internal spreading plate 12 of the stirring kettle 1. The spreading plate 12 is provided with evenly distributed through holes to allow the glue to drip onto the fiber raw material on the lower side. Further, through the stirring shaft 2 rotation can drive the scraper 13 to rotate, so that the rotation of the scraper 13 can spread the glue gathered on the spreading plate 12, so that the spread glue is more even when dripping down through the through holes on the spreading plate 12.

When the screw rod 16 rotates counterclockwise, it fits with the inner wall of the discharge pipe 17, so that it can play the role of a screw feeder. It has a simple structure and is flexible to use.
