Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically a mixing and temperature control device for electrophoretic coating production. Background Technology

[0002] Electrophoretic paint, also known as electrophoretic coating, has become increasingly popular as the defects of conventional spraying have become increasingly apparent. Electrophoretic paint has also been continuously updated and upgraded, from anodic electrophoretic paint to cathodic electrophoretic paint, from single-component electrophoretic paint to two-component electrophoretic paint. The development of electrophoretic paint has also promoted the development of electrophoretic coating, enabling more and more products to use electrophoresis instead of spraying technology.

[0003] In the production process of electrophoretic coatings, the uniformity of raw material mixing and temperature control are crucial to product quality. According to Chinese Patent Publication No. CN113856543A, a mixing and temperature control device for electrophoretic coating production is disclosed. It controls an electric heating plate to heat the inner cavity of a second chamber through a temperature controller, and controls a cooler to cool the inner cavity of the second chamber through a temperature controller. A thermal sensor and an electric heating plate are paired one-to-one. When the thermal sensor detects that the electric heating plate cannot generate heat, the thermal sensor transmits a signal to a buzzer, and the buzzer alarms to remind the staff to repair or replace the electric heating plate.

[0004] However, in this technical solution, the electric heating plate body is installed outside the second box, which means that the heat of the electric heating plate body needs to be conducted to the material through the second box, resulting in a certain amount of heat loss, which affects the heat conduction efficiency and thus the temperature control efficiency. To address this, we propose a mixed temperature control device for electrophoretic coating production. Utility Model Content

[0005] The purpose of this invention is to provide a mixing and temperature control device for electrophoretic coating production, which solves the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mixing and temperature control device for electrophoretic coating production, comprising a mixing tank, an opening at the top of the mixing tank, a cover plate covering the top of the opening, a fixing ring fixedly installed at the top of the mixing tank, the cover plate being rotatably connected to the fixing ring, a support frame fixedly installed at the top of the mixing tank, a motor fixedly installed at the top of the support frame, a rotating shaft fixedly installed at the output end of the motor, the rotating shaft being fixedly inserted through the cover plate into the interior of the mixing tank, a stirring plate fixedly installed on the outer wall of the rotating shaft, a through hole opened on the cover plate, a heating rod movably passing through the through hole, a top plate fixedly installed at the top of the heating rod, a shaft groove opened at the top of the cover plate, a connecting shaft inserted into the shaft groove, a torsion spring fixedly connected between the outer wall of the connecting shaft and the inner wall of the shaft groove, and the connecting shaft being rotatably connected to the shaft groove, a clamping plate fixedly installed at the top of the connecting shaft, the clamping plate being clamped to the top of the top plate, and a power supply fixedly installed at the top of the cover plate, the power supply being electrically connected to the heating rod;

[0007] A temperature controller is fixedly installed on the outer wall of the mixing tank, and a temperature sensor is fixedly installed on the top of the inner wall of the mixing tank. The temperature sensor is electrically connected to the temperature controller, and the temperature controller is electrically connected to a power source.

[0008] Preferably, the outer wall of the cover plate is inlaid with rolling balls, and the inner wall of the fixing ring is provided with a rolling groove. The rolling balls are in rolling connection with the rolling groove. By setting the rolling balls and the rolling groove, the cover plate can be limited, so that the cover plate can be fixedly rotated on the fixing ring, and the friction is greatly reduced.

[0009] Preferably, a sealing ring plate is fixedly installed at the bottom of the cover plate, and a sealing ring groove is opened at the top of the mixing tank. The sealing ring plate and the sealing ring groove are rotatably connected. By setting the sealing ring plate and the sealing ring groove, the sealing performance between the cover plate and the mixing tank can be improved, and heat loss can be avoided.

[0010] Preferably, a fixing cylinder extends through the inner wall of the through hole, a sponge is fixedly installed on the inner wall of the fixing cylinder, the sponge is tightly fitted onto the outer wall of the heating rod, a locking block is fixedly installed on the outer wall of the fixing cylinder, the locking block is engaged in a slot opened in the inner wall of the through hole, a limit block is slidably connected to the top of the locking block, a limit groove is opened in the inner wall of the slot opened in the through hole, and the limit block is inserted into the limit groove.

[0011] Preferably, a slider is fixedly installed at the bottom of the limiting block, and the slider is slidably connected to the groove opened at the top of the card block. A limiting rod is fixedly installed on the inner wall of the groove opened at the top of the card block. The limiting rod moves through the slider. By moving the limiting block, the limiting block is disengaged from the limiting groove. At this time, the fixing cylinder can be pulled upward to disengage from the through hole, so that the sponge can be disassembled and replaced.

[0012] Preferably, the stirring plate has a rod hole, through which the heating rod moves. A feed pipe is connected to one side of the mixing tank near the top, a discharge pipe is connected to the bottom of the mixing tank, and an exhaust pipe is connected to the top of the mixing tank. By providing the rod hole, the stirring plate can provide a certain degree of support and limit for the heating rod.

[0013] This invention provides a mixing and temperature control device for electrophoretic coating production. This mixing and temperature control device for electrophoretic coating production has the following advantages:

[0014] (1) The mixing temperature control device for electrophoretic coating production can make the heating rod directly contact the material, thereby improving the heat transfer efficiency between the heating rod and the material. When the temperature of the heating rod changes, the temperature of the material can be changed relatively quickly, which improves the temperature control efficiency. This solves the problem that in the existing technical solution, the electric heating plate body is installed outside the second box, which causes the heat of the electric heating plate body to be conducted to the material through the second box, resulting in a certain heat loss, which affects the heat transfer efficiency and thus affects the temperature control efficiency.

[0015] (2) The mixing temperature control device for electrophoretic coating production, through the fixed cylinder and the sponge, can absorb the coating attached to the heating rod when the heating rod is disassembled, clean the surface of the heating rod, and prevent a lot of coating from flowing out with the heating rod and dripping onto the working environment, causing great pollution to the working environment.

[0025] Example 1

[0026] A preferred embodiment of the mixing and temperature control device for electrophoretic coating production provided by this utility model is, for example... Figures 1 to 5As shown: A mixing and temperature control device for electrophoretic coating production includes a mixing tank 1 with an opening at the top. A cover plate 6 covers the top of the opening. A fixing ring 27 is fixedly installed at the top of the mixing tank 1, and the cover plate 6 is rotatably connected to the fixing ring 27. A support frame 2 is fixedly installed at the top of the mixing tank 1, and a motor 3 is fixedly installed at the top of the support frame 2. A rotating shaft 4 is fixedly installed at the output end of the motor 3, extending through the cover plate 6 into the interior of the mixing tank 1. A stirring plate 5 is fixedly installed on the outer wall of the rotating shaft 4. The cover plate 6... The top has a through hole 8, through which a heating rod 11 moves. A top plate 7 is fixedly installed at the top of the heating rod 11. A shaft groove 13 is opened at the top of the cover plate 6. A connecting shaft 12 is inserted into the shaft groove 13. A torsion spring 14 is fixedly connected between the outer wall of the connecting shaft 12 and the inner wall of the shaft groove 13. The connecting shaft 12 is rotatably connected to the shaft groove 13. A clamping plate 17 is fixedly installed at the top of the connecting shaft 12 and clamps the top of the top plate 7. A power supply 23 is fixedly installed at the top of the cover plate 6 and is electrically connected to the heating rod 11.

[0027] A temperature controller 31 is fixedly installed on the outer wall of the mixing tank 1, and a temperature sensor 32 is fixedly installed on the top of the inner wall of the mixing tank 1. The temperature sensor 32 is electrically connected to the temperature controller 31, and the temperature controller 31 is electrically connected to the power supply 23.

[0028] Specifically, in the above technical solution, when the mixing and temperature control device for electrophoretic coating production is in use, the motor 3 can be started, the motor 3 drives the rotating shaft 4 to rotate, the rotating shaft 4 drives the cover plate 6 and the stirring plate 5 to rotate, the stirring plate 5 stirs the material in the mixing tank 1, and the cover plate 6 drives the heating rod 11 to rotate in the mixing tank 1 at the same time, increasing the flow contact between the heating rod 11 and the material, thereby improving the heat transfer efficiency between the heating rod 11 and the material. In addition, the temperature inside the mixing tank 1 is sensed by a thermal sensor. When it is necessary to adjust the temperature in the mixing tank 1, the power supply 23 can be controlled by the temperature controller 31 to raise or lower the temperature of the heating rod 1. The heating rod 11 stirs the material, which can quickly change the temperature of the material, thus improving the temperature control efficiency. Through the above structure, the heating rod 11 can be in direct contact with the material, thereby improving the heat transfer efficiency between the heating rod 11 and the material. Moreover, when the temperature of the heating rod 11 changes, the temperature of the material can be changed relatively quickly, thus improving the temperature control efficiency. This solves the problem in the existing technical solution where the electric heating plate body is installed outside the second box, which causes the heat of the electric heating plate body to be conducted to the material through the second box, resulting in a certain amount of heat loss, which affects the heat transfer efficiency and thus the temperature control efficiency.

[0029] Furthermore, the outer wall of the cover plate 6 is inlaid with rolling balls 26, and the inner wall of the fixing ring 27 is provided with a rolling groove 28, and the rolling balls 26 are in rolling connection with the rolling groove 28.

[0030] By setting the ball bearing 26 and the groove 28, the cover plate 6 can be limited, so that the cover plate 6 can rotate fixedly on the fixed ring 27, and the friction is greatly reduced.

[0031] Furthermore, a sealing ring plate 24 is fixedly installed at the bottom of the cover plate 6, and a sealing ring groove 25 is opened at the top of the mixing tank 1. The sealing ring plate 24 and the sealing ring groove 25 are rotatably connected.

[0032] By setting the sealing ring plate 24 and the sealing ring groove 25, the sealing performance between the cover plate 6 and the mixing tank 1 can be improved, thus preventing heat loss.

[0033] Furthermore, the stirring plate 5 has a rod hole, the heating rod 11 moves through the rod hole, the mixing tank 1 has a feed pipe 29 connected to one side near the top, the mixing tank 1 has a discharge pipe 30 connected to the bottom, and the mixing tank 1 has an exhaust pipe 33 connected to the top.

[0034] In this design, the stirring plate 5 is designed with rod holes to provide support and limit the heating rod 11.

[0035] Example 2

[0036] Based on Embodiment 1, a preferred embodiment of the mixing and temperature control device for electrophoretic coating production provided by this utility model is, for example... Figures 1 to 5 As shown: A fixing cylinder 9 passes through the inner wall of the through hole 8. A sponge 10 is fixedly installed on the inner wall of the fixing cylinder 9. The sponge 10 is tightly fitted on the outer wall of the heating rod 11. A locking block 18 is fixedly installed on the outer wall of the fixing cylinder 9. The locking block 18 is engaged in the locking groove opened in the inner wall of the through hole 8. A limiting block 19 is slidably connected to the top of the locking block 18. A limiting groove 20 is opened in the inner wall of the locking groove opened in the inner wall of the through hole 8. The limiting block 19 is inserted into the limiting groove 20.

[0037] Specifically, in the above technical solution, when it is necessary to disassemble the heating rod 11, the clamping plate 17 can be rotated, causing the clamping plate 17 to drive the connecting shaft 12 to twist the torsion spring 14, so that the clamping plate 17 is disengaged from the top of the top plate 7. Then, the top plate 7 can be pulled upwards directly, causing the top plate 7 to move the heating rod 11 upwards. When the heating rod 11 moves upwards, the sponge 10 will absorb the coating attached to the heating rod 11, cleaning the surface of the heating rod 11 and preventing a large amount of coating from flowing out with the heating rod 11 and dripping onto the working environment, causing significant pollution to the working environment.

[0038] Furthermore, a slider 21 is fixedly installed at the bottom of the limiting block 19. The slider 21 is slidably connected to the groove opened at the top of the locking block 18. A limiting rod 22 is fixedly installed on the inner wall of the groove opened at the top of the locking block 18. The limiting rod 22 moves through the slider 21.

[0039] By moving the limiting block 19, the limiting block 19 is disengaged from the limiting groove 20. At this time, the fixing cylinder 9 can be pulled upward to disengage from the through hole 8, so that the sponge can be disassembled and replaced.

[0040] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
