Description

Technical Field

[0001] The utility model relates to the technical field of powder coating bonding equipment, in particular to a large bonding equipment with a rapid heating-up and switching water-cooling system. Background Art

[0002] The bonding machine is a professional equipment for producing metal-bonded powder. It perfectly pastes and embeds metal powder on the surface of powder coating particles to complete the process of metal powder coating bonding. For example, aluminum powder, copper powder, etc. can bond to produce excellent effects such as flash silver, flash gold, pearlescent, and mirror silver. However, after the existing powder coating bonding machine is heated at high temperature, the cooling is slow and uneven. The long-term high temperature will cause damage to the driving device of the bonding machine, etc., and it is prone to shutdown, which is not conducive to the processing efficiency. Therefore, we have designed a large bonding equipment with a rapid heating-up and switching water-cooling system.

[0003] A Chinese utility model patent with the patent number CN202322810641.0 discloses a bonding machine for producing powder coatings, including a machine table. The upper surface of the machine table is provided with a bonding box. An inlet hopper is inserted eccentrically at the top surface of the bonding box. A heat source chamber is arranged between the inner wall and the outer wall of the bonding box. A heat inlet nozzle communicated with the heat source chamber is fixedly installed on the outer surface of the bonding box. A stirring motor is arranged at the center of the top surface of the bonding box, and the heat supply port is located below the other side of the machine table; by setting the first air duct and the second air duct to communicate with the inner wall of the heat source chamber, the air in the heat source chamber can have an up-and-down circulation structure. At the same time, the setting of the exhaust fan and the blower can make the air inside the heat source chamber have a blowing and exhausting circulation state, which can accelerate the high-temperature drop speed inside the heat source chamber. The setting of this device can avoid the damage of the remaining driving components caused by the residual heat after the machine table is heated, and can accelerate the air circulation speed and cool down quickly. However, this utility model has the following problems: First, it does not have uniform cooling, and the cooling means is single, and the rapid cooling effect is poor. Second, the heat dissipation port does not have the function of automatically opening and closing, and the manual method has low safety and affects the work efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the technical problems that after the existing powder coating bonding machine is heated at high temperature, the cooling is slow and uneven, the long-term high temperature will cause damage to the driving device of the bonding machine, etc., and it is prone to shutdown, which is not conducive to the processing efficiency, by setting a first convection port, a second convection port, a spiral heating pipe, a spiral water-cooling pipe, and a heat dissipation metal pipe.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of this utility model with reference to the drawings.

[0024] Embodiment 1

[0025] As Figures 1 to 5As shown in the figure, the utility model provides a large bonding device for a rapid heating and switching water-cooling system, including a device main body 1. There is a bonding chamber inside the device main body 1. Metal powder is perfectly pasted and embedded on the surface of powder coating particles in the bonding chamber. A receiving cavity 2 is arranged in the sandwich layer of the device main body 1, providing an installation space for a spiral heating pipe 4, a spiral water-cooling pipe 5, and a heat dissipation metal pipe 6. A temperature sensor 3 is arranged on the lower surface of the receiving cavity 2 to monitor the temperature inside the receiving cavity 2. A spiral heating pipe 4 is arranged at the inner diameter surface position of the receiving cavity 2, and hot water is arranged inside the pipe, which can heat up the bonding chamber to promote the bonding of metal powder. A spiral water-cooling pipe 5 is arranged in the spiral gap of the spiral heating pipe 4, and cold water is arranged inside the pipe, which plays a role in cooling the bonding chamber. Both the spiral heating pipe 4 and the spiral water-cooling pipe 5 are spirally coiled, increasing the contact area with the inner diameter surface of the receiving cavity 2, and can realize uniform heating or uniform cooling of the bonding chamber. A heat dissipation metal pipe 6 is arranged between the spiral water-cooling pipe 5 and the outer diameter surface of the receiving cavity 2, which is supported by copper material. The heat in the bonding chamber inside the device main body 1 is absorbed by the cold water in the spiral water-cooling pipe 5, causing the water temperature to rise. The heat dissipation metal pipe 6 uses its good heat conduction ability to transfer the heat in the water to the surface of the device main body 1, increasing the efficiency of heat dissipation and cooling. And the heat dissipation metal pipe 6 also plays a reinforcing role in the receiving cavity 2. And the upper end of the spiral water-cooling pipe 5 is provided with a water-cooling inlet pipe 51, and the lower end of the spiral water-cooling pipe 5 is provided with a water-cooling outlet pipe 52. Both the water-cooling inlet pipe 51 and the water-cooling outlet pipe 52 perpendicularly protrude on the outer surface of the device main body 1. The water-cooling inlet pipe 51 and the water-cooling outlet pipe 52 are respectively connected to an external water-cooling box structure, so that cold water enters the water-cooling inlet pipe 51, flows through the spiral water-cooling pipe 5 and the water-cooling outlet pipe 52, and returns to the external water-cooling box structure with the absorbed heat.

[0026] Further, as Figure 4 shown, the upper end of the spiral heating pipe 4 is provided with a heating inlet pipe 41, and the lower end of the spiral heating pipe 4 is provided with a heating outlet pipe 42. Both the heating inlet pipe 41 and the heating outlet pipe 42 perpendicularly protrude on the outer surface of the device main body 1. The heating inlet pipe 41 and the heating outlet pipe 42 are respectively connected to an external heating box structure, so that hot water enters the heating inlet pipe 41, flows through the spiral heating pipe 4 and the heating outlet pipe 42, and returns to the external heating box structure.

[0027] Further, as Figure 5As shown, support feet 7 are evenly distributed at the lower edge position of the device body 1, increasing the height from the ground and maintaining cleanliness. At the rear side position of the lower end of the device body 1, there is a first convection port 8. At the lower end of the first convection port 8, there is a flip cover 81. A sealing ring 82 is provided between the flip cover 81 and the first convection port 8. The inner diameter of the flip cover 81 is greater than the outer diameter of the first convection port 8, and the gap between the two is filled by the sealing ring 82 to reduce the heat dissipation during heating. At the front end of the flip cover 81, there is a connecting member 86. The left and right ends of the connecting member 86 are movably connected to fixed seats 83. After the powder bonding is completed, the relevant motors and transmission components provided in the fixed seats 83 work, causing the connecting member 86 to rotate, automatically opening the flip cover 81. At the same time, the air cooling structure 85 is powered on to work, causing upper and lower air convection to form in the accommodation cavity 2, increasing the cooling rate and improving the automation level of the device.

[0028] Furthermore, one end of the first convection port 8 far from the flip cover 81 communicates with the accommodation cavity 2. In the middle position of the inner surface of the first convection port 8, there is a hollow fixed mounting seat 84, which provides an installation position for the air cooling structure 85 without affecting the ventilation and heat dissipation effect. At the end of the mounting seat 84 far from the flip cover 81, there is an air cooling structure 85, including structures such as a motor, a rotating shaft, and an impeller, enabling the combination of air cooling and water cooling for effective heat dissipation.

[0029] Furthermore, as Figure 1 shown, an upper cover 9 is provided at the upper end of the device body 1. The upper cover 9 seals the upper end of the device body 1. At the front end of the upper cover 9, there is a second convection port 10. The structure and size of the second convection port 10 are the same as those of the first convection port 8. An upper and lower convection is formed between the second convection port 10 and the first convection port 8, increasing the air flow in the accommodation cavity 2, thereby taking away more heat and improving the cooling efficiency.

[0030] Furthermore, a stirring motor 11 is provided in the middle of the upper end of the upper cover 9. The operation of the stirring motor 11 can drive the stirring structure in the bonding chamber to stir. At the rear side position of the upper end of the upper cover 9, there is a feed port 12, and the powder material enters from here.

[0031] Working process: first, pour the material from the feed port 12, and while the stirring motor 11 is powered on, the hot water in the external heating box structure passes through the heating inlet pipe 41, flows through the spiral heating tube 4, and the heating outlet pipe 42 to form a hot water circulation, so that the temperature of the bonding chamber in the equipment body 1 increases, so that the metal powder is bonded evenly; further, when the metal powder bonding is completed, the external water cooling box structure is powered on, so that cold water enters the water cooling inlet pipe 51, flows through the spiral water cooling tube 5, and the water cooling outlet pipe 52, and returns to the external water cooling box structure with the absorbed heat, forming circulating water cooling; at the same time, the relevant motor and transmission components in the fixed seat 83 are powered on, so that the connecting piece 86 rotates, so that the flip cover 81 opens automatically, and at the same time the air cooling structure 85 is powered on, so that the upper and lower air convection is formed in the accommodating chamber 2, thereby increasing the cooling rate.
