Description

Technical Field

[0001] This utility model relates to the technical field of powder coating production equipment, and more specifically, to a cooling conveyor belt for a tablet press used in powder coating production. Background Technology

[0002] In the powder coating production process, molten material is extruded from the extruder die and pressed into thin sheets by pressure rollers. The sheets then need to be rapidly cooled and solidified on a cooling conveyor belt to ensure the smooth progress of subsequent crushing and micronization processes.

[0003] However, existing cooling conveyor belts have the problem of poor cooling effect. During the conveying process, the molten material sheets are generally cooled by natural wind and fans. Over a long period of use, the conveyor belt temperature is prone to become too high, resulting in uneven temperature at the contact surface between the sheet and the conveyor belt, causing unstable sheet quality, such as inconsistent thickness and uneven surface, which affects the final quality of powder coating. In view of this, we propose a cooling conveyor belt for a tablet press for powder coating production. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a cooling conveyor belt for a tablet press for powder coating production. This solves the technical problem that the current conveyor belt will experience temperature rise when conveying molten material sheets for a long time, resulting in uneven temperature on the upper and lower surfaces of the sheets, and defects such as inconsistent thickness and uneven surface.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a cooling conveyor belt for a tablet press for powder coating production, including a conveyor body, baffles fixedly installed on both sides of the frame of the conveyor body, fans with opposite air outlets connected to the baffles on both sides, and cooling components that contact the bottom surface of the top conveyor belt of the conveyor body fixedly installed between the opposing surfaces of the two baffles.

[0006] The cooling component includes two limiting tubes fixedly connected to the baffle, and the two limiting tubes are respectively the water inlet and the water outlet. A cooling pipe is fixedly connected between the two limiting tubes. A cooling sleeve is rotatably installed on the outer side of the cooling pipe, which contacts the bottom surface of the top conveyor belt of the conveyor body.

[0007] This invention reduces the airflow range through a baffle design. Fans with opposing airflow are installed on both sides of the conveyor's main frame, and cooling components are incorporated to contact the bottom surface of the conveyor belt, achieving a dual cooling system of air and water. The opposing fans change the airflow direction to cool the conveyor belts on both sides, while the cooling pipes and cooling sleeves in the cooling components further reduce the temperature of the conveyor belt and powder coating through circulating cooling water. This reduction in conveyor belt surface temperature significantly improves cooling efficiency, shortens the cooling time of the powder coating, and thus enhances the overall production efficiency of the tablet press.

[0008] Preferably, the outer surface of the cooling sleeve is integrally formed with a plurality of arrayed resistance blocks, and the conveyor belt of the conveyor body is arrayed with a plurality of ventilation holes that cooperate with the resistance blocks.

[0009] Preferably, a spiral blade is fixedly installed inside the cooling pipe, and a flow-reducing pipe is inserted between the centers of the spiral blade to reduce the flow rate of cooling water.

[0010] Preferably, the thickness of both the cooling pipe and the cooling sleeve is between 2mm and 6mm, and both the cooling pipe and the cooling sleeve are made of thermally conductive materials, and the contact surfaces of the cooling pipe and the cooling sleeve are smooth surfaces.

[0011] Preferably, two limiting grooves are formed on the outer surface of the cooling pipe, and a limiting ring that engages with the limiting grooves is fixedly provided on the inner side of the cooling sleeve.

[0012] Preferably, both the resistance block and the ventilation hole are rectangular in shape, and the longer side of the ventilation hole is longer than the longer side of the resistance block.

[0013] Preferably, each of the two limiting tubes is fixedly provided with a connecting sleeve at its side end, and each of the two connecting sleeves is fixedly connected with a water pipe for entering and exiting cooling water.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model reduces the airflow range through baffle design. Opposite-direction fans are installed on both sides of the conveyor's main frame, and cooling components are installed to contact the bottom surface of the conveyor belt, achieving a dual cooling method of air and water cooling. The opposing-direction fans change the airflow direction to cool the conveyor belts on both sides, while the cooling pipes and cooling sleeves in the cooling components further reduce the temperature of the conveyor belt and powder coating through circulating cooling water. The reduction in the surface temperature of the conveyor belt greatly improves cooling efficiency, shortens the cooling time of the powder coating, and thus improves the overall production efficiency of the tablet press.

[0016] 2. This utility model also features a rotatable cooling sleeve that rotates in conjunction with a resistance block and ventilation holes. This facilitates automatic changes in the contact area between the cooling sleeve and the conveyor belt on the main body of the conveyor, further improving the stability of heat exchange. The spiral blades and flow-reducing tubes inside the cooling sleeve effectively change the flow path and speed of the cooling water, prolonging the residence time of the cooling water in the cooling sleeve and increasing the contact area between the cooling water and the inner wall of the cooling sleeve. This enhances the heat exchange effect and ensures that the cooling sleeve maintains a stable heat exchange and cooling effect at different locations, further improving the uniformity of heat exchange on the conveyor belt.

[0023] like Figures 1 to 5 As shown, this utility model relates to a cooling conveyor belt for a powder coating production tablet press, comprising a conveyor body 1. Baffles 101 are fixedly installed on both sides of the frame of the conveyor body 1. Fans 2 with opposing airflow are connected and installed on the walls of both baffles 101. Cooling components 3, which contact the bottom surface of the conveyor belt at the top of the conveyor body 1, are fixedly installed between the opposing surfaces of the two fans 2. The two baffles 101 can enclose the interior of the conveyor belt of the conveyor body 1, thereby reducing the airflow range of the fans 2. A partition 103 is also fixedly connected between the two baffles 101, which can divide the airflow into multiple airflow ranges, further improving the cooling effect. The contact between the cooling components 3 and the conveyor belt allows for heat exchange with the conveyor belt and also allows for heat absorption of the thin sheets, improving the cooling effect of the thin sheets.

[0024] The cooling component 3 includes two limiting tubes 301 fixedly connected to the baffle 101, with the two limiting tubes 301 being the water inlet and water outlet respectively. A cooling pipe 302 is fixedly connected between the two limiting tubes 301. A cooling sleeve 303 is rotatably installed on the outer side of the cooling pipe 302, which contacts the bottom surface of the top conveyor belt of the conveyor body 1. The water inlet and water outlet of the circulation pipe can be connected to the two limiting tubes 301 respectively, which facilitates the recycling of cooling water. The circulation pipe is an existing technology structure and will not be described in detail here. The rotatable design of the cooling sleeve 303 allows it to rotate under the friction of the conveyor belt, thereby automatically changing the contact surface with the conveyor belt and maintaining the stability of heat exchange.

[0025] In the embodiments of this utility model, the outer surface of the cooling sleeve 303 is integrally formed with a plurality of arrayed resistance blocks 304, and the conveyor belt of the conveyor body 1 is arrayed with a plurality of ventilation holes 102 that cooperate with the resistance blocks 304; the cooperation between the resistance blocks 304 and the ventilation holes 102 can push the resistance blocks 304 to move during the movement of the conveyor belt, so that the cooling sleeve 303 can maintain a stable rotation effect, further improving the heat exchange effect of the cooling sleeve 303 on the surface of the conveyor belt.

[0026] In an embodiment of this utility model, a spiral blade 307 is fixedly provided inside the cooling pipe 302, and a flow-reducing pipe 308 is inserted between the centers of the spiral blade 307 to reduce the flow rate of the cooling water; the spiral blade 307 causes the cooling water to flow in a spiral shape inside the cooling pipe 302, prolonging the residence time of the cooling water in the pipe and fully absorbing heat; the flow-reducing pipe 308 can reduce the space inside the limiting pipe 301 and reduce the flow rate of the cooling water.

[0027] In the embodiments of this utility model, the thickness of both the cooling pipe 302 and the cooling sleeve 303 is between 2mm and 6mm, and both the cooling pipe 302 and the cooling sleeve 303 are made of thermally conductive materials. The contact surfaces of the cooling pipe 302 and the cooling sleeve 303 are smooth surfaces. The thickness design can maintain stable thermal conductivity, and the smooth surface can reduce frictional resistance, making it easier for the cooling sleeve 303 to rotate along the outer surface of the cooling pipe 302.

[0028] In an embodiment of this utility model, two limiting grooves 305 are formed on the outer surface of the cooling pipe 302, and a limiting ring 306 that engages with the limiting grooves 305 is fixedly provided on the inner side of the cooling sleeve 303; the installation position of the cooling sleeve 303 can be restricted by the cooperation of the two.

[0029] In the embodiments of this utility model, both the resistance block 304 and the ventilation hole 102 are rectangular in shape, and the length of the long side of the ventilation hole 102 is greater than the length of the long side of the resistance block 304. The difference in length is conducive to the resistance block 304 being inserted into the interior of the ventilation hole 102, which facilitates the synchronous displacement and combination of the two, so as to achieve the effect of stably pushing the cooling sleeve 303 to rotate.

[0030] In the embodiments of this utility model, a connecting sleeve 309 is fixedly provided on the side end of each of the two limiting tubes 301, and a water pipe 310 for entering and exiting cooling water is fixedly connected to the side end of each of the two connecting sleeves 309; the water pipe 310 can be connected to the inlet and outlet of the circulation pipe respectively, which facilitates connection to an external cooling water circulation device.

[0031] Working Principle: This embodiment provides a cooling conveyor belt for a powder coating production tablet press. In use, the conveyor body 1 serves as the basic carrier of the entire equipment. Baffles 101 fixedly installed on both sides of its frame reduce the airflow range and also fix the installation position of the fans 2. Opposite-facing exhaust fans 2 are connected to the walls of the baffles 101. By blowing out opposing airflows, an air convection environment can be formed inside the conveyor belt. The partition 103 between the two baffles 101 further reduces the airflow range, effectively cooling the upper and lower inner surfaces of the conveyor belt and the surface of the cooling components 3. This segmented cooling enhances the cooling effect on the conveyor belt surface. Simultaneously, the cooling components 3 fixedly installed between the opposing surfaces of the baffles 101 directly contact the bottom surface of the conveyor belt at the top of the conveyor body 1, undertaking the main cooling work. The cooling components 3 consist of a limiting pipe 301, a cooling pipe 302, and a cooling sleeve 303. Two limiting pipes 301, serving as the water inlet and outlet respectively, are fixedly connected to the baffles 101 for introducing and discharging cooling water. The cooling pipes 302, fixedly connected between the limiting pipes 301, are filled with cooling water, which circulates within the pipes, continuously carrying away heat. A cooling sleeve 303, rotatably mounted on the outer surface of the cooling pipes 302, contacts the bottom surface of the conveyor belt. When the conveyor belt runs, friction drives the cooling sleeve 303 to rotate, changing its contact position with the conveyor belt. This maintains good heat exchange and improves heat transfer efficiency. An integrally formed resistance block 304 on the outer surface of the cooling sleeve 303 cooperates with the ventilation holes 102 on the conveyor belt. When the conveyor belt runs, the contact between the resistance block 304 and the ventilation holes 102 pushes the resistance block 304 to move, ensuring stable rotation of the cooling sleeve 303. Furthermore, the fan 2 blows air directly onto the bottom surface of the sheet through the ventilation holes 102, improving ventilation and heat dissipation. The spiral blades 307 fixedly installed inside the cooling pipes 302 and the flow-reducing pipe 308 passing through the center work together to optimize the flow of the cooling water. The spiral blade 307 causes the cooling water to flow in a spiral shape within the cooling pipe 302, extending the residence time of the cooling water within the pipe and allowing for full heat absorption. The flow-reducing pipe 308 reduces the flow rate of the cooling water, allowing the cooling water more time to absorb heat within the pipe and improving cooling efficiency. This overall structural coordination can improve the stability of heat exchange and cooling, maintain stable temperatures on the upper and lower parts of the sheet, and improve the subsequent processing quality of the sheet.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
