Description

Technical Field

[0001] This utility model relates to the field of coating production and processing technology, and in particular to a high-reflectivity powder coating production and processing device. Background Technology

[0002] High-reflectivity powder coatings are widely used in solar reflectors, LED lighting, architectural decoration, and other fields. Their high reflectivity requires excellent smoothness and uniformity of the coating surface. In traditional production processes, molten material is extruded through an extruder and then rapidly cooled and pressed into sheets using a single-stage cooling roller, followed by crushing and grinding. However, this process presents the following technical problems:

[0003] 1. A sudden drop in temperature of a single-stage cooling roller can easily lead to uneven distribution of thermal stress inside the coating, resulting in microcracks or warping, which affects the mechanical properties and reflectivity of the coating.

[0004] 2. Rapid cooling may reduce the compatibility between the resin and high-reflectivity fillers (such as titanium dioxide, barium sulfate, etc.), resulting in defects such as orange peel and pinholes on the surface, and reducing the reflectivity and gloss of the coating.

[0005] 3. When crushing the cooled molten material, it is necessary to cut it to facilitate crushing. However, when the material is cut after solidification, due to the high hardness of the material, the cutting is prone to chipping or micro-cracks, which affects the edge reflection performance and increases the wear of the cutting tools.

[0006] 4. The existing cooling, cutting, and crushing processes are carried out in segments, resulting in a discontinuous production process and affecting overall efficiency;

[0007] Therefore, there is an urgent need for a powder coating production device that can achieve step-by-step controllable cooling, efficient semi-curing and slitting, and optimized surface reflectivity. Utility Model Content

[0008] In order to overcome the shortcomings of the prior art, this utility model discloses a high-reflectivity powder coating production and processing device. This utility model can not only effectively reduce the internal defects of the material by cooling and pressing the molten material in stages, but also perform efficient and stable cutting and conveying of the material during the cooling and pressing process, which greatly improves the cooling and pressing efficiency and quality of the molten material.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A high-reflectivity powder coating production and processing apparatus includes a mounting frame, and further includes:

[0011] Several cooling roller groups are arranged sequentially and at intervals within the mounting frame, with the cooling temperature of the cooling roller groups decreasing sequentially, for the step-by-step cooling and pressing of continuously conveyed molten material.

[0012] The separation mechanism is located at the rear of each cooling roller group and is used to separate the cooling sheets that are adhered to the roller surface of the cooling roller group and to guide the cooling sheets horizontally.

[0013] The slitting mechanism, located at the rear of the cooling roller group in the middle, is used to slit the cooled sheets.

[0014] Furthermore, the mounting frame includes two rectangular frames arranged vertically and vertically, with several connecting rods evenly distributed on both sides of the opposite surfaces of the two rectangular frames.

[0015] Furthermore, the cooling roller assembly includes two cooling rollers arranged vertically and vertically, with the two cooling rollers in each cooling roller assembly being rotatably mounted in two rectangular frames.

[0016] Furthermore, at least three sets of cooling rollers are provided, with a temperature difference between each set of cooling rollers between 10℃ and 40℃.

[0017] Furthermore, the separation mechanism includes:

[0018] Two guide plates are installed in two rectangular frames, respectively, and are arranged parallel to each other. The two guide plates work together to form a conveying path for horizontally guiding and conveying the cooling press plate.

[0019] Mounting rods are located on both sides of the guide plate and are used to connect with the rectangular frame;

[0020] An arc-shaped scraper is located at the end of the guide plate and is fitted with the adjacent cooling roller surface with a clearance.

[0021] Furthermore, rollers are embedded in the opposing surfaces of both guide plates for rotational mounting.

[0022] Furthermore, the slitting mechanism includes:

[0023] The slitting roller assembly includes two slitting rollers and an auxiliary roller, which are arranged vertically and vertically and are respectively located within two rectangular frames.

[0024] Two conveyor roller groups are respectively set on the front and rear sides of the slitting roller group. The conveyor roller group includes two conveyor rollers that are arranged vertically and vertically and are respectively set in two rectangular frames.

[0025] Furthermore, the slitting roller surface is provided with several annular blades arranged in an orderly manner at intervals along the axial direction of the slitting roller, and the auxiliary roller surface is provided with several annular grooves that correspond one-to-one with the annular blades.

[0026] Compared with the prior art, the beneficial effects of this utility model are: by using a series of cooling rollers with gradually decreasing temperatures, the molten material can be cooled and pressed into sheets in stages, allowing the material to slowly release thermal stress and reduce internal defects;

[0027] By setting up a separation mechanism, not only can the cooling sheets that are stuck to the surface of the cooling roller be separated, but the horizontal and stable conveying of the cooling sheets can also be ensured, providing strong support for the efficient cooling and pressing of molten materials.

[0028] By setting up a cutting mechanism, the cooled pressed sheets can be cut, which not only facilitates the feeding operation of subsequent crushing and grinding equipment, but also makes them easier to store.

[0029] By setting the slitting mechanism at the rear of the cooling roller group in the middle, the slitting efficiency of the cooling sheet can be effectively improved, the wear of the blades in the slitting mechanism can be reduced, and the situation of micro-cracks or edge chipping that are easy to occur when slitting the cooling sheet after curing can be avoided, thus reducing the impact on the uniformity of coating edge reflection.

[0030] This invention not only effectively reduces internal defects in molten materials by cooling and pressing them into tablets through gradual cooling, but also enables efficient and stable cutting and conveying of materials during the cooling and pressing process. This greatly improves the efficiency of cooling and pressing molten materials and provides significant convenience for the subsequent crushing and storage of the cooled tablets.

[0040] The technical solution of this utility model will be described below with reference to the accompanying drawings of the embodiments of this utility model. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this utility model for the convenience of describing this utility model, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0041] Please refer to the instruction manual appendix. Figure 1-5 This utility model provides a technical solution:

[0042] Example 1: A high-reflectivity powder coating production and processing device includes a mounting frame 1. The mounting frame 1 includes two rectangular frames 11 arranged vertically and vertically. Several connecting support rods 12 are evenly distributed on both sides of the opposite face of the two rectangular frames 11. The mounting frame 1 is provided with several cooling roller groups 2 arranged sequentially and at intervals, which are used to cool and press the continuously conveyed molten material into sheets in stages. The cooling roller group 2 includes two cooling rollers 21 arranged vertically and vertically. The two cooling rollers 21 in each cooling roller group 2 are rotatably installed in the two rectangular frames 11 respectively. The cooling roller 21 includes a roller body, a cooling medium channel, a bearing and a rotation system.

[0043] The strip-shaped molten material extruded by the twin-screw extruder is conveyed to the mounting frame 1 via traction rollers. Multiple cooling roller groups 2 in the mounting frame 1 cool and press the molten material into sheets. In order to slowly release the thermal stress of the material and reduce internal defects, at least three cooling roller groups 2 are set up. The temperature difference between each cooling roller group 2 is between 10℃ and 40℃. For example, the temperature of the cooling roller 21 of the first cooling roller group 2 is 120℃, the temperature of the cooling roller 21 of the second cooling roller group 2 is 90℃, and the temperature of the cooling roller 21 of the third cooling roller group 2 is 60℃. The temperature of the cooling roller 21 is adjusted according to the material of the molten material.

[0044] In Example 2, during the process of progressively cooling and pressing molten material into sheets using multiple sets of cooling rollers 2, the molten material being cooled and pressed into sheets easily adheres to the surface of the cooling rollers 21, affecting the normal cooling and pressing of subsequent molten material. Therefore, a separation mechanism 3 is provided at the rear of each cooling roller set 2 to separate the cooled sheets adhering to the roller surface and to guide them horizontally. Specifically, the separation mechanism 3 has two guide plates 31, which are respectively installed within two rectangular frames 11 and arranged parallel to each other. The two guide plates 31 cooperate to form a cooling... The conveying path for horizontally guiding the pressing of the tablets is provided. Both sides of the two guide plates 31 are provided with mounting rods 33 connected to the rectangular frame 11. The ends of the two guide plates 31 near the cooling roller 21 are provided with arc-shaped scrapers 32 that are adapted to the roller surface of the cooling roller 21. The arc-shaped scrapers 32 are fitted with the roller surface of the cooling roller 21 with a clearance. The scraper head of the arc-shaped scraper 32 is attached to the roller surface of the cooling roller 21. In order to ensure that the sheet-like molten material separated by the arc-shaped scraper 32 can continue to be smoothly conveyed horizontally along the conveying path, the opposite surfaces of the two guide plates 31 are each embedded with a roller that rotates in the same direction as the cooling roller 21.

[0045] In Example 3, during the cooling and pressing process of molten material, the molten material after cooling and pressing is either temporarily stored or directly sent to a crushing and grinding equipment for crushing. Because the molten material after cooling and pressing has a large area, it is not only inconvenient to store but also difficult to send smoothly to the crushing and grinding equipment. Therefore, the molten material after cooling and pressing needs to be cut and crushed before further processing. However, because the molten material after cooling and pressing is relatively hard, it is prone to micro-cracks or edge chipping during cutting and crushing, thus affecting the uniformity of coating edge reflection. Therefore, a slitting mechanism 4 for cutting the cooled and pressed material is provided at the rear of the cooling roller group 2 in the middle. Specifically, the slitting mechanism 4 includes a slitting roller group 42 and a conveying roller group 41. Conveying roller groups 41 for horizontally conveying the sheet-like molten material are provided on both the front and rear sides of the slitting roller group 42. The conveying roller group 41 includes two upper and lower pairs of... The conveying rollers 411 are set and respectively located within two rectangular frames 11. The slitting roller group 42 includes two slitting rollers 421 and an auxiliary roller 422, which are arranged vertically and vertically within the two rectangular frames 11. The slitting roller 421 has several annular blades 4211 arranged in an orderly manner along the axial direction of the slitting roller 421. The auxiliary roller 422 has several annular grooves 4221 that correspond to and match the annular blades 4211. By using the cooperation of the slitting roller 421 and the auxiliary roller 422, the sheet-like molten material can be efficiently slitted. Since the molten material at this position has not been completely solidified, it not only reduces the wear of the annular blades 4211 and improves the cutting efficiency, but also avoids damage to the structure of the sheet-like molten material. In order to save energy, the cooling roller group 2 and the cooling roller group 42 and the conveying roller group 41 in the slitting mechanism 4 are driven synchronously by a sprocket drive.
