Description

Technical Field

[0001] This utility model relates to the field of reaction vessels, and in particular to a quantitative feeding device for a cathodic electrophoretic paint reaction vessel. Background Technology

[0002] In a broad sense, a reaction vessel is a container that undergoes physical or chemical reactions. Through structural design and parameter configuration of the container, the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process can be achieved. Electrophoretic paint, also known as electrophoretic coating, is used by placing the workpiece as an electrode in a water-diluted paint tank. The paint particles are charged and deposited on the surface of the workpiece by using an electric field. A certain amount of raw materials are added to the reaction vessel during the preparation of electrophoretic paint.

[0003] Most current quantitative feeding devices involve manually weighing the materials before adding them to the reactor. Some of these devices use small weighing containers, requiring multiple measurements and additions by the staff, which is cumbersome and increases the workload. Therefore, a quantitative feeding device for cathodic electrophoretic paint reactors is needed. Utility Model Content

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] 1. In this utility model, a drive motor is set as the power source. The drive motor drives the first transmission gear to rotate. Under the drive of the second transmission gear, the third transmission gear rotates in the same direction as the first transmission gear.

An injection pipe 7 is fixedly connected to the inner wall of the injection hole. The end of the injection pipe 7 away from the collection box 6 penetrates the inner top wall of the reactor body 3.

[0025] With the above structure, the base plate 1 is set as the installation platform, the heat preservation box 2 is made of heat preservation material, which can reduce the heat loss in the reactor body 3, the raw material box 5 contains liquid raw materials, and the installation box 8 can isolate external interference and ensure the normal operation of internal parts.

[0027] By setting the sleeve 17 as a feeding gauge, the push rod 19, piston 18 and sleeve 17 form a syringe. When the up and down stroke of piston 18 is constant, the raw material sucked into sleeve 17 is quantitative.

[0028] Preferably, a water suction hole is provided on the upper side of the sleeve 17, and a water suction pipe 20 is fixedly connected to the inner wall of the water suction hole. A water suction one-way valve 21 is fixedly connected to the surface of the water suction pipe 20. The end of the water suction pipe 20 away from the sleeve 17 passes through the inner top wall of the raw material box 5 and extends to the bottom of the raw material box 5.

[0029] By setting a one-way valve 21 to restrict the flow direction of the raw material, when the piston 18 moves downward, the raw material can only flow from the raw material box 5 to the sleeve 17.

[0030] Preferably, a water outlet hole is provided on the upper side of the sleeve 17, and a water outlet pipe 22 is fixedly connected to the inner wall of the water outlet hole. A water outlet one-way valve 23 is fixedly connected to the surface of the water outlet pipe 22, and the end of the water outlet pipe 22 away from the sleeve 17 passes through the inner top wall of the collecting box 6.

[0031] By setting a one-way valve 23 to restrict the flow direction of the raw material, when the piston 18 moves downward, the raw material can only flow from the sleeve 17 to the collecting box 6.

[0032] Preferably, a first transmission gear 10 is rotatably connected to the left inner wall of the mounting box 8, a second transmission gear 11 is rotatably connected to the left inner wall of the mounting box 8, and a third transmission gear 12 is rotatably connected to the left inner wall of the mounting box 8. The first transmission gear 10 meshes with the second transmission gear 11, and the second transmission gear 11 meshes with the third gear.

[0033] By setting three gears of the same size and specifications for power transmission, the third transmission gear 12 rotates in the same direction with the first transmission gear 10 at the same angular velocity under the drive of the second transmission gear 11.

[0034] Preferably, a first drive gear 13 is fixedly connected to the right side of the first transmission gear 10, a second drive gear 14 is fixedly connected to the right side of the third transmission gear 12, a double-sided drive rack 16 is fixedly connected to the lower side of the connecting plate 15, the right side of the double-sided drive rack 16 is slidably connected to the right inner wall of the mounting box 8, the double-sided drive rack 16 meshes with the first drive gear 13, the double-sided drive rack 16 meshes with the second drive gear 14, a drive motor 9 is fixedly connected to the right side of the mounting box 8, and the output end of the drive motor 9 passes through the right inner wall of the mounting box 8 and is fixedly connected to the right side of the first drive gear 13.

[0035] By setting the first drive gear 13 and the second drive gear 14, which have only half of the transmission teeth, to drive the double-sided drive rack 16 to move, since the first drive gear 13 rotates coaxially with the first transmission gear 10, and the second drive gear 14 rotates coaxially with the third gear, the double-sided drive rack 16 can perform reciprocating motion in the up and down direction.

[0036] The working principle of this utility model is as follows: A quantitative feeding device for a cathodic electrophoretic paint reactor adds the required raw materials into the raw material box 5, and then starts the drive motor 9. The drive motor 9 drives the first drive gear 13 and the first transmission gear 10 to rotate. The rotation of the first transmission gear 10 drives the second transmission gear 11 to rotate. The rotation of the second transmission gear 11 drives the third transmission gear 12 to rotate. The rotation of the third transmission gear 12 drives the second drive gear 14 to rotate. Since the first drive gear 13 and the second drive gear 14 only have half of their transmission teeth, the double-sided drive rack 16 can move up and down. The reciprocating motion of the piston 18 causes the double-sided drive rack 16 to move, which in turn drives the connecting bar to move. The connecting bar then drives the push rod 19 to move, which in turn drives the piston 18 to reciprocate downwards. When the piston 18 moves downwards, due to the restriction of the suction check valve 21, the raw material in the raw material tank 5 is sucked into the sleeve 17 through the suction pipe 20. When the piston 18 moves upwards, the raw material in the sleeve 17 is injected into the collection box through the outlet pipe 22, and finally injected into the reactor body 3 through the injection pipe 7. The user can determine the number of suction pipes 20 inserted into the raw material tank 5 according to the required amount of raw material.
