Description

Technical Field

[0001] The utility model relates to the field of bonding machines, in particular to a powder coating bonding machine with stable temperature monitoring. Background Art

[0002] The bonding technology of metal powder coating is to add powder coating base powder into the bonding machine and raise the temperature of the base material mixture. When the material temperature rises to a temperature close to the glass transition temperature (Tg) of the resin, the metal pigment is quickly added to the powder to make it bond to the surface of the softened powder coating particles, and then the material is quickly discharged for cooling. This is the bonding process of powder coating. In the bonding process, temperature monitoring is particularly important, but the temperature probe of the existing bonding machine must be inserted into the inside of the bonding machine. The powder coating will adhere to the temperature probe, which affects the accuracy of the temperature display in the cylinder. After bonding two cylinders continuously, there will be a thick layer of powder attached to the surface of the probe, which seriously affects the timely and accurate display of the continuous production temperature. Especially when making products with high content of metal pigments, high-temperature bonding will cause the paddle to jam due to inaccurate display temperature; at the same time, in order to increase the detection range of temperature detection, the existing bonding machine usually installs multiple temperature sensors to check the temperature at different heights in the bonding machine.

[0003] The current temperature-monitored and stable powder coating bonding machine, as described in the patent with announcement number CN208990650U, includes a kettle cover and a vertically arranged kettle body, the kettle cover is detachably connected to the upper end of the kettle body, the upper part of the kettle cover is connected with a lower hopper, the bottom of the kettle body is equipped with a stirring mechanism, the bottom of the kettle body is connected with a discharge pipe, the kettle cover is equipped with a temperature measuring mechanism, the temperature measuring mechanism includes a vertically arranged machine base, the machine base is fixedly installed on the upper wall of the kettle cover, the upper part of the machine base is equipped with a cylinder, the cylinder is connected with a vertically arranged piston rod, the upper end of the piston rod is drivingly connected with the cylinder, the lower end of the piston rod is connected with a vertically arranged temperature measuring rod, the kettle cover is provided with a vertically arranged through hole, the lower part of the machine base is provided with a vertically arranged guide hole, and the position of the through hole corresponds to the position of the guide hole.

[0004] Regarding the above-mentioned related technologies, the inventor believes that in the process of the cylinder driving the temperature measuring rod and the temperature measuring sensor downward, they will come into contact with the raw materials on the upper layer, resulting in that when the temperature measuring sensor descends to the required temperature measurement height, the temperature measuring sensor will still be covered with powder from the upper layer, resulting in poor stability of temperature monitoring.

DETAILED DESCRIPTION

[0024] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0025] See also Figure 1-4 A powder coating bonding machine with stable temperature monitoring includes a bonding mechanism 1, which includes a kettle 101. The kettle 101 is used to accommodate raw materials to be bonded. A motor 102 is fixedly connected to the bottom of the kettle 101, and a stirring paddle 105 is fixedly connected to the output end of the motor 102. The motor 102 can drive the stirring paddle 105 to rotate when starting work. The stirring paddle 105 is located inside the kettle 101, so that the stirring paddle 105 can stir and mix the raw materials inside the kettle 101. A connected feed pipe 104 is fixedly connected to one side of the top of the kettle 101. The setting of the feed pipe 104 facilitates the addition of required raw materials into the kettle 101.

[0026] A discharge valve 103 is fixedly connected to one side of the bottom of the kettle body 101, and the discharge valve 103 is used to discharge the material inside the kettle body 101 when it is opened. The temperature measuring mechanism 2 includes a heat-insulating sleeve 201 that passes through and slides on the top of the kettle body 101, and an annular plate 203 is fixedly connected to the inside of the heat-insulating sleeve 201, and an electric telescopic rod 202 is fixedly passed through the inside of the annular plate 203, and the setting of the annular plate 203 can support and fix the electric telescopic rod 202. The output end of the electric telescopic rod 202 is fixedly connected to a connecting block 204, the bottom of the connecting block 204 is fixedly connected to a temperature measuring rod 205, the interior of the temperature measuring rod 205 is fixedly connected to a temperature sensor 207, the temperature measuring rod 205 passes through the bottom of the insulation sleeve 201, and is slidably connected to the insulation sleeve 201. When the electric telescopic rod 202 is started, it can drive the connecting block 204 and the temperature measuring rod 205 to move up and down, so that the temperature sensor 207 can be extended out of the insulation sleeve 201 to facilitate the temperature sensor 207 to measure the temperature.

[0027] The bottom of the temperature measuring rod 205 is fixedly connected with a bottom block 208. The setting of the bottom block 208 can shield the bottom of the insulation sleeve 201 to reduce the probability of the raw material entering the insulation sleeve 201 from the bottom of the insulation sleeve 201. The bottom of the connection block 204 is symmetrically fixedly connected with connecting rods 206. Both groups of connecting rods 206 penetrate the insulation sleeve 201 and are slidably connected to the insulation sleeve 201. The ends of the two groups of connecting rods 206 away from the connection block 204 are fixedly connected to the bottom block 208. The setting of the connecting rods 206 can connect and fix the bottom block 208 with the connection block 204, thereby improving the stability of the bottom block 208. The adjusting mechanism 3 includes a top plate 301 fixedly connected to the top of the heat insulating sleeve 201, and a spring 302 is fixedly connected between the top plate 301 and the top wall of the kettle body 101.

[0028] A traction rope 303 is fixedly connected to one side of the top plate 301, and a winch 304 is fixedly connected to the top of the kettle body 101. The end of the traction rope 303 away from the top plate 301 is fixedly connected to the output end of the winch 304.

A limit rod 308 fixedly connected to the inner wall of the kettle body 101 is provided below the bottom block 208. The setting of the limit rod 308 can limit the downward movement of the insulation sleeve 201 and the bottom block 208, so as to reduce the probability of the bottom block 208 touching the stirring paddle 105.

[0029] A suspension rod 309 is fixedly connected to one side of the top of the limiting rod 308, and one end of the suspension rod 309 away from the limiting rod 308 is fixedly connected to the inner top wall of the kettle body 101. The setting of the suspension rod 309 can further connect and fix the limiting rod 308 to the kettle body 101, thereby improving the installation stability of the limiting rod 308. A sliding rod 306 is fixedly connected to one side of the bottom of the top plate 301, and a reinforcing rib plate 307 is fixedly connected to the side of the sliding rod 306 away from the traction rope 303.

The setting of the reinforcing rib plate 307 can further connect and fix the sliding rod 306 to the top plate 301, thereby improving the connection stability between the sliding rod 306 and the top plate 301. The outer side of the slide rod 306 is slidably connected to a slide rail 305 , and the slide rail 305 is fixedly connected to the outer wall of the kettle body 101 . The arrangement of the slide rod 306 and the slide rail 305 can guide the up and down movement of the top plate 301 and the insulation sleeve 201 .

[0030] In this embodiment, the temperature sensor 207 is a prior art and will not be described in detail herein.

[0031] When in use, the raw materials are poured into the interior of the kettle body 101 through the feed pipe 104, and then the feed pipe 104 is covered, and then the motor 102 is started, so that the motor 102 drives the stirring paddle 105 to rotate, thereby stirring the raw materials in the kettle body 101. When it is necessary to detect the temperature of the raw materials, the winch 304 can be started, so that the winch 304 can wind the traction rope 303 when starting work, thereby driving the top plate 301 and the insulation sleeve 201 to move downward until the insulation sleeve 201 is adjusted to the desired temperature. The required height is reached, and then the electric telescopic rod 202 is started, so that the electric telescopic rod 202 starts to extend, thereby driving the connecting block 204, the temperature measuring rod 205 and the temperature sensor 207 to move downward until the temperature sensor 207 extends out of the insulation sleeve 201. Then the temperature sensor 207 can measure the temperature of the raw material at the corresponding depth, so that the temperature measuring rod 205 does not contact the coating at other depths, thereby reducing the probability that the coating at other depths will affect the measurement result, thereby further improving the stability of temperature monitoring.
