Description

Technical Field

[0001] The utility model relates to the technical field of coating production, and more specifically to a water-based epoxy topcoat filling device. Background Art

[0002] After the coating production line has gone through the processes of batching, adding materials, mixing, dispersing and grinding, blending, preparation, filtering and testing, it needs to be packaged and canned with the help of a filling machine. At present, when the filling machine produces certain specific active coatings, the uneven internal and external pressure will cause the feeding speed to slow down, which not only affects the efficiency of filling, but also may cause the coating to be unable to be discharged and filled. In addition, it is difficult to control the filling process, and it is easy to fill it insufficiently or too much. In addition, excessive pressure relief can easily lead to the deterioration of coatings and the mixing of a large amount of air into the coating. After the coating is transferred to the filling machine, it is easy to be accompanied by bubbles in the can, which affects the quality. Utility Model Content

DETAILED DESCRIPTION

[0019] Example:

[0020] The following is combined with Figure 1-4The utility model is described in further detail.

[0021] Waterborne epoxy topcoat filling device, such as Figure 1 As shown, the main body is a main frame 20 with a transfer chamber 10, and the bottom of the main frame 20 has four legs. A fixed transfer chamber 10 is provided on the main frame 20, and a filling unit 30 and a voltage stabilizing unit 40 that can slide up and down are provided on the legs. The filling unit 30 and the voltage stabilizing unit 40 move synchronously.

[0022] Among them, Figure 2 As shown, the transfer chamber 10 has a rectangular box structure at its upper end and a square angular funnel-shaped structure at its lower end. An arched bottom surface 11 is provided inside the transfer chamber 10. The cross-sections of the sides at both ends of the arched bottom surface 11 are semicircular or elliptical structures. Two symmetrical discharge ports 12 are provided at the top of the arched bottom surface 11. The discharge ports 12 are downwardly connected to the filling unit 30. A feed port 13 is provided on the side of the transfer chamber 10.

[0023] like Figure 3 As shown, the filling unit 30 includes a docking pipe 31, a control valve 32, a filling head 33, a connecting angle plate 35, a tank placing platform 36 and a sliding assembly. The docking pipe 31, the control valve 32 and the filling head 33 are a set of matching structures, which need to be set according to the number of fillings in a batch. In this embodiment, two sets of symmetrical docking pipes 31 are provided, taking the filling of two barrels in a batch as an example. The docking pipes 31 are connected to the opening at the bottom of the transfer chamber 10 and are bent to a horizontal position. The control valve 32 is installed on the docking pipe 31. The other end of the control valve 32 is connected to the filling head 33. The filling head 33 is a straight tube type material discharge nozzle. The connection between the docking pipe 31 and the filling head 33 is controlled by the control valve 32. The control valve 32 is a manual valve or an electric valve, and the control valve 32 is equipped with a flow meter for auxiliary operation. The connecting angle plate 35 is an L-shaped plate, which is installed on the adjacent sides of the two front legs 21. The two connecting angle plates 35 are symmetrically arranged, and a slide groove 34 is opened at the inner end, and a sliding assembly is installed in the slide groove 34. The horizontal cross section of the tank placing platform 36 is a convex structure, the convex end is embedded between the legs 21, and at the same time docks with the sliding components at both ends, and the sliding components on both sides operate synchronously. The sliding components drive the tank placing platform 36 to slide up and down along the slide groove 34 to meet the filling of tanks of different heights. In addition, the top surface of the tank placing platform 36 is provided with symmetrical tank placing grooves, and the center of the tank placing grooves is aligned with the center of the nozzle of the filling head 33, which is convenient for auxiliary positioning during filling.

[0024] like Figure 4As shown, the pressure stabilizing unit 40 includes a pressure relief pipe 41, a regulating pipe 42, a swirl tail pipe 43 and a regulating pump 44. The regulating pump 44 is used for mechanical pressure regulation. The regulating pump 44 is connected to the top of the injection head 33 and directly affects the injection action. A pressure relief pipe 41 is provided on the top of the regulating pump 44 to discharge the internal pressure. The pressure relief pipe 41 is a straight pipe as a whole. A regulating pipe 42 is provided on the top of the pressure relief pipe 41. The regulating pipe 42 is a pipe that is symmetrical up and down and shrinks in the middle section. A swirl tail pipe 43 is provided on the top of the regulating pipe 42. The opening of the swirl tail pipe 43 is set in the countryside. The setting of the swirl tail pipe 43 needs to ensure that the height of the opening is higher than the height of the bottom of the regulating pipe 42, so that the pressure can be released smoothly. Special pipeline sealing rings 50 are provided between the docking pipeline 31 and the control valve 32, between the docking pipeline 31 and the transfer chamber 10, and between the injection head 33 and the regulating pump 44.

[0025] The paint enters the transfer chamber 10 from the feed port 13 on the side of the transfer chamber 10. Due to the height difference, bubbles will inevitably float on the surface of the paint during feeding. The paint is discharged in an overflow manner using the arched bottom surface 11. Bubbles will accumulate near the side wall of the transfer chamber 10. Therefore, when the paint accumulates in the transfer chamber 10 and the liquid levels on both sides do not converge, the central arched discharge port first discharges the paint without bubbles in the center; after the liquid levels of the paint on both sides converge, the paint discharged is the paint at the bottom that is even less likely to have bubbles. The paint is discharged from the transfer chamber 10 and enters the filling head 33 along the docking pipe 31 and the opened control valve 32. The filling head 33 is aligned with the placed tank body for filling and packaging. At this time, the regulating pump 44 is running to discharge the pressure increased by the increase in the paint inside. Along the pressure discharge pipe 41, the pressure is adjusted by the buffer adjustment and rotary buffer adjustment of the contraction and release of the regulating pipe 42 to achieve segmented pressure adjustment. Basically, the structure can be adjusted by itself without human intervention.

[0026] It should be noted that this specific embodiment is merely an explanation of the present utility model, and it is not a limitation of the present utility model. After reading this specification, those skilled in the art can make non-creative modifications to the present embodiment as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
