Description

Technical Field

[0001] This utility model relates to the field of resin manufacturing technology, and in particular to an apparatus for preparing E0 grade modified urea-formaldehyde resin adhesive. Background Technology

[0002] The E0 grade modified urea-formaldehyde resin adhesive preparation device is a device used to produce E0 grade urea-formaldehyde resin adhesive with low formaldehyde emission. Urea-formaldehyde resin is an adhesive commonly used in wood gluing, furniture manufacturing and other industries. It has good adhesive properties, but traditional urea-formaldehyde resin has a high formaldehyde emission, which does not meet environmental protection requirements. E0 grade means that the formaldehyde emission reaches the lowest or almost zero level under certain standards, which meets more stringent environmental protection requirements. The core function of this device is to carry out the synthesis process of urea-formaldehyde resin adhesive through stirring. In the preparation process, the ingredients of urea-formaldehyde resin adhesive (urea, formaldehyde, etc.) are added to the container, and the polymerization reaction of the resin is completed under the conditions of mechanical stirring and heat energy. However, existing urea-formaldehyde resin preparation equipment requires manual operation during the mixing process, which presents a series of inconveniences. Specifically, in traditional urea-formaldehyde resin preparation equipment, the mixing process usually relies on manual operation, requiring workers to judge the speed, time, and force of mixing based on experience. Manual mixing not only demands a high level of experience from operators, but also, due to the different operating methods of each worker, makes it difficult to guarantee the quality and consistency of each batch of resin. This inefficient operation method results in a long production cycle, affecting overall production capacity and work efficiency. Furthermore, the difficulty in precisely controlling the judgment and force of manual mixing can lead to uneven resin mixing ratios, which in turn affects the chemical reaction process of the resin. This instability not only affects the performance of the urea-formaldehyde resin but may also lead to unstable formaldehyde emission control in the final product, failing to fully meet the E0 environmental protection standard, which is a problem that urgently needs to be solved. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this invention provides an E0-grade modified urea-formaldehyde resin adhesive preparation device. Traditional manual operation relies on workers' experience to control the speed, time, and force of the mixing. This method is not only inefficient, but also results in inconsistent quality and consistency of each batch of resin adhesive due to the different operating techniques of each worker. This device provides precisely controllable reciprocating mixing power through a drive component, avoiding the fluctuations of manual operation. After the drive motor starts, the belt and pulley achieve a speed reduction and torque increase effect, ensuring that the mixing frequency and force are adjustable, thereby ensuring uniform mixing of materials and improving the quality stability of the resin adhesive.

[0004] To solve the above technical problems, this utility model provides the following technical solution: an E-grade modified urea-formaldehyde resin adhesive preparation device, including an installation frame, an installation plate installed on the installation frame, a limiting component provided inside the installation plate, a preparation container fixedly connected to the installation plate through the limiting component, a driving component installed on the installation frame, the output end of the driving component being connected to a tamping roller, and the tamping roller being placed at the upper end of the preparation container.

[0005] As a preferred technical solution of this utility model, the drive assembly includes a drive motor fixedly mounted on the mounting frame, a first pulley connected to the output end of the drive motor, a belt wound around the first pulley, a second pulley wound around the other end of the belt and rotatably connected to the outer wall of the mounting frame, a rotating shaft connected to the second pulley, a turntable connected to the other end of the rotating shaft, a convex shaft mounted on the outer wall of the turntable, and a hinge rod hinged to the convex shaft, wherein the other end of the hinge rod is hinged to the tamping roller.

[0006] In a preferred embodiment of this invention, the diameter of the first pulley is smaller than that of the second pulley, and the rotating shaft is fixed at the center of the turntable.

[0007] As a preferred embodiment of this utility model, a guide groove is installed on the mounting frame, and the hinge rod is inserted into the guide groove.

[0008] As a preferred technical solution of this utility model, the limiting component includes a fixing cavity formed in the mounting plate, a threaded groove formed on the side wall of the mounting plate, a pin inserted into the threaded groove, an external thread formed on the outer wall of the pin, and a limiting groove formed on the side wall of the preparation container.

[0009] As a preferred embodiment of this utility model, the external thread is formed on the rear end wall of the pin, and the external thread is threadedly connected to the threaded groove.

[0010] As a preferred technical solution of this utility model, the outer ring diameter of the pin is set to be equal to the inner ring diameter of the limiting groove.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are: 1. Traditional manual operation relies on workers' experience to control the speed, time, and force of tamping. This method is not only inefficient, but also makes it difficult to guarantee the quality and consistency of each batch of resin glue due to the different operating techniques of each worker. This device provides precisely controllable reciprocating tamping power through the drive component, avoiding the fluctuations of manual operation. After the drive motor starts, it achieves speed reduction and torque increase through belts and pulleys, ensuring that the frequency and force of tamping are adjustable, thereby ensuring uniform mixing of materials and improving the quality stability of the resin glue.

[0012] 2. The device requires no manual intervention throughout the entire process. It controls the tamping rollers to perform uniform up-and-down tamping movements at the top of the preparation container by driving the motor, eliminating errors that may occur in manual operation. The frequency of the tamping rollers is controlled by the motor speed, while the force is determined by the belt pulley transmission ratio, which further improves the accuracy and consistency of the preparation process. This automated operation method significantly improves production efficiency and reduces the impact of human factors on the consistency of product quality.

[0013] 3. Traditional manual mixing is prone to uneven resin mixing due to unstable operation, which affects the chemical reaction of the resin and even the formaldehyde release of the final product, making it unable to fully meet the Class E environmental protection standard. This device, through precise reciprocating motion and sufficient mixing force, ensures that all components of the resin are in full contact and react evenly, ultimately stabilizing the formaldehyde release of the product, meeting environmental protection standards, and improving product quality.

[0017] Example

[0018] like Figure 1-5 As shown, an E0 grade modified urea-formaldehyde resin adhesive preparation device includes an installation frame 1, an installation plate 2 installed on the installation frame 1, a limiting component 6 installed inside the installation plate 2, a preparation container 3 fixedly connected to the installation plate 2 through the limiting component 6, a driving component 5 installed on the installation frame 1, the output end of the driving component 5 being connected to a tamping roller 4, and the tamping roller 4 being placed at the upper end of the preparation container 3. The drive assembly 5 includes a drive motor 51 fixedly mounted on the mounting frame 1, a first pulley 52 connected to the output end of the drive motor 51, a belt 53 wound around the first pulley 52, a second pulley 54 wound around the other end of the belt 53 and rotatably connected to the outer wall of the mounting frame 1, a rotating shaft 55 connected to the second pulley 54, a turntable 56 connected to the other end of the rotating shaft 55, a convex shaft 57 mounted on the outer wall of the turntable 56, and a hinge rod 58 hinged to the convex shaft 57, wherein the other end of the hinge rod 58 is hinged to the tamping roller 4.

[0019] The core function of the drive component is to replace manual labor and provide precisely controllable reciprocating tamping power. The power transmission and action realization process is as follows: After the drive motor 51, which is fixed to the mounting frame 1, is started, the output shaft drives the first pulley 52 to rotate. Since the diameter of the first pulley 52 is smaller than that of the second pulley 54, the transmission effect of the belt 53 is used to achieve the effect of deceleration and torque increase. This reduces the tamping frequency to ensure that the material is fully mixed, and increases the tamping torque to ensure uniform mixing force, avoiding the problem of inconsistent force during manual operation. The second pulley 54 drives the turntable 56 to make uniform circular motion through the rotating shaft 55. The rotating shaft 55 is fixed in the middle position of the turntable 56 to ensure the concentricity of rotation. The convex shaft 57 on the outer wall of the turntable 56 moves synchronously in a circular motion with the turntable. Since the convex shaft 57 is off-center from the turntable, its motion trajectory forms an eccentric circle. The convex shaft 57 is hinged to the hinge rod 58, and the hinge rod 58 is inserted into the guide groove of the mounting frame 1. The guide groove restricts the hinge rod to move only in the vertical direction. Therefore, the eccentric circular motion of the convex shaft 57 is converted into the up-and-down reciprocating linear motion of the hinge rod 58. The other end of the hinge rod 58 is hinged to the tamping roller 4. With the reciprocating motion of the hinge rod, the tamping roller 4 performs a uniform up-and-down tamping action at the upper end of the preparation container 3. The tamping frequency is controlled by the speed of the drive motor 51, and the force is determined by the belt pulley transmission ratio, that is, the speed reduction and torque increase effect. No manual intervention is required throughout the process.

[0020] The limiting component 6 includes a fixing cavity 61 formed in the mounting plate 2, a threaded groove 62 formed on the side wall of the mounting plate 2, a pin 63 inserted into the threaded groove 62, an external thread 64 formed on the outer wall of the pin 63, and a limiting groove 65 formed on the side wall of the preparation container 3. The core function of the limiting component 6 is to prevent the preparation container 3 from loosening and shifting during the tamping process, ensuring that the tamping trajectory accurately covers the material inside the container. Its fixing mechanism is as follows: the preparation container 3 is placed in the fixing cavity 61 of the mounting plate 2. The size of the fixing cavity 61 matches the preparation container 3, achieving initial positioning. The operator rotates the pin 63. Since the external thread 64 on the rear wall of the pin 63 is threadedly connected to the threaded groove 62 on the side wall of the mounting plate 2, the pin 63 is pushed towards the container along the threaded groove 62. The front end of the pin 63 is finally inserted into the limiting groove 65 on the side wall of the preparation container 3. The outer diameter of the pin 63 is completely consistent with the inner diameter of the limiting groove 65, forming a double fixation of thread locking and groove fitting, ensuring that the preparation container 3 has no displacement or shaking during the tamping process. The rigid fixation of the container avoids uneven mixing caused by the material shaking with the container during tamping, ensuring that the force of the tamping roller 4 is accurately transmitted to the inside of the material, so that the components of the resin glue can fully contact and react evenly.

[0021] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
