Description

Technical Field

[0001] This utility model relates to the field of emulsion polymerization preparation technology, and in particular to an adhesive structure for a coating device. Background Technology

[0002] Coating and laminating equipment is a device used to coat or laminate substrates, widely used in packaging, printing, building materials, electronics, and other industries. With technological advancements and increasing market demand, coating and laminating technology plays an increasingly important role in improving product quality, extending product lifespan, and enhancing aesthetics. The development of coating and laminating equipment has gone through several stages. Early coating technologies mainly relied on manual brushing and spraying, methods that, while simple, suffered from low efficiency and inconsistent quality. In the early 20th century, the development of the chemical industry led to the emergence of various new coatings and laminating materials, which in turn spurred innovation in coating and laminating equipment. In the mid-to-late 20th century, automated coating and laminating equipment became widespread, such as spraying equipment, dipping equipment, roller coating equipment, and blade coating equipment.

[0003] To enhance the adhesion between the coating or film and the substrate, ensuring that the coating or film firmly adheres to the material surface, it is necessary to increase the tackiness of the coating or film. The core technology of the fully automated, environmentally friendly surface coating device for plastic packaging container processing is the emulsion polymerization preparation technology.

[0004] However, existing preparation techniques suffer from drawbacks such as raw material quality issues, contamination during transportation and storage, and the potential presence of large particulate impurities in monomers and emulsifiers, which affect the stability of the emulsion and the performance of the final product. Therefore, there is a need to propose a viscosity-enhancing structure for the coating / film-coating device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where large particulate impurities may exist in monomers and emulsifiers, affecting the stability of the emulsion and the performance of the final product. This invention proposes a viscosity-enhancing structure for a coating and film-coating device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adhesive enhancement structure for a coating and film covering device, comprising a mixing cylinder, a filter box fixedly installed at the top of the mixing cylinder, a filtration mechanism disposed inside the filter box, a vibration mechanism disposed outside the filter box, a water bath mechanism disposed outside the mixing cylinder, a mixing mechanism disposed inside the mixing cylinder, several support legs fixedly installed at the bottom of the mixing cylinder, a discharge pipe connected to the bottom of the mixing cylinder, the filtration mechanism comprising a first material cylinder and a second material cylinder movably disposed inside the filter box, filter screen plates fixedly installed at the bottom of the inner sidewalls of the first material cylinder and the second material cylinder, a pair of feed hoppers connected to the top of the filter box, and conveying hoses connected to the bottom of both the first material cylinder and the second material cylinder, the ends of the conveying hoses penetrating the top of the mixing cylinder to the interior.

[0007] The bottom ends of the two feed hoppers are respectively located above the first material cylinder and the second material cylinder, and the inner walls of the first material cylinder and the second material cylinder are located below the feed hoppers when they are in motion; this is used to filter the raw materials to avoid impurities in the raw materials from affecting the emulsion polymerization method and thus affecting the viscosity of the coating device. The raw materials enter the first material cylinder and the second material cylinder through the feed hoppers, and after being filtered by the filter screen, the raw materials enter the mixing cylinder through the conveying hose.

[0008] Preferably, the vibration mechanism includes a sliding rod fixedly installed on the outer walls of the first and second material cylinders. Sliding strips are fixedly installed on the outer walls of both the first and second material cylinders. The sliding rod slides through the outer wall of the filter box, and the sliding strips slide through the other outer wall of the filter box. A limiting plate is fixedly installed at the end of the sliding rod. A functional spring is sleeved on the sliding rod, elastically connected between the outer wall of the filter box and the inner wall of the limiting plate. A drive motor is fixedly installed on the outer wall of the filter box, positioned between a pair of sliding strips. A sector gear is fixedly installed on the output shaft of the drive motor. Several fixed locking teeth are fixedly installed on adjacent sides of the pair of sliding strips, with the sector gear engaging with the fixed locking teeth. This mechanism is used to vibrate the first and second material cylinders, preventing excessive raw material accumulation within them. Normally, the functional spring is in a relaxed state. In the relaxed state, the drive motor is started, which drives the sector gear to rotate. The sector gear initially engages with the fixed teeth on the sliding bar fixedly connected to the first material cylinder, thereby pushing the first material cylinder to move. The first material cylinder pushes the limiting plate through the sliding rod, stretching the corresponding functional spring. As the sector gear disengages from the fixed teeth, the first material cylinder is reset under the reaction force of the functional spring. Subsequently, the sector gear engages with the fixed teeth on the sliding bar fixedly connected to the second material cylinder, thereby pushing the second material cylinder to move. The second material cylinder is pulled to the limiting plate through the sliding rod, compressing the corresponding functional spring. As the sector gear disengages from the fixed teeth, the second material cylinder is reset under the reaction force of the functional spring. This cycle repeats, thereby controlling the vibration of the first and second material cylinders and preventing excessive raw material from accumulating in the first and second material cylinders.

[0009] Preferably, the water bath mechanism includes a water bath cylinder fixedly installed on the outer wall of the mixing cylinder, a plurality of electric heating tubes evenly and equidistantly fixedly installed on the inner wall of the water bath cylinder, a water inlet pipe connected to the bottom end of the outer wall of the water bath cylinder, and a drain pipe connected to the top end of the outer wall of the water bath cylinder; it is used to heat the mixing cylinder with water. When the electric heating tubes are activated, external water enters the water bath cylinder from the water inlet pipe, and the electric heating tubes heat the water to achieve the heating treatment of the mixing cylinder. Then the hot water is discharged from the drain pipe, thereby realizing the circulation of the water source.

[0010] Preferably, the mixing mechanism includes a rotating rod rotatably mounted between the top and bottom ends of the mixing cylinder, with stirring blades evenly and uniformly fixedly mounted on the rotating rod, and a forward and reverse motor fixedly mounted at the bottom end of the mixing cylinder. The output shaft of the forward and reverse motor is coaxially and fixedly connected to the rotating rod. It is used for mixing raw materials. When the forward and reverse motor is started, the forward and reverse motor drives the rotating rod to rotate, and the rotating rod drives the stirring blades to rotate, thereby achieving the mixing of raw materials.

[0011] The present invention has the following beneficial effects: 1. By setting up a filtration mechanism, the raw materials enter the first and second material cylinders through the feed hopper. After being filtered by the filter screen, the raw materials enter the mixing cylinder through the conveying hose to filter the raw materials and avoid impurities in the raw materials from affecting the emulsion polymerization method and thus affecting the viscosity of the coating device.

[0012] 2. By setting up a vibration mechanism and starting the drive motor, the drive motor drives the sector gear to rotate. The sector gear cyclically meshes with the fixed clamping teeth. The first material cylinder pushes the limit plate through the sliding rod, which stretches the corresponding functional spring. The second material cylinder is pulled to the limit plate through the sliding rod, which compresses the corresponding functional spring. Under the reaction force of the functional spring, the first and second material cylinders are reset. This cycle repeats, so that the vibration treatment of the first and second material cylinders can prevent excessive raw materials from accumulating in the first and second material cylinders.
