In the prior art, a ball valve is usually installed on the drain port, and the ball valve is used to open or close the drain port. However, in actual application, the opening and closing of the drain port is controlled by a ball valve, which is prone to dead angles, resulting in residual cleaning water after drainage, which brings inconvenience to the drying process after cleaning. If it cannot be completely dried, it is easy to breed bacteria and other microorganisms, thereby affecting product quality. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a water accumulation pan for a coating machine provided with a flat-bottom valve structure, wherein drainage is achieved by opening the flat-bottom valve, and drainage is smooth and residue-free; after drainage, the flat-bottom valve is closed to form an effective seal on the drainage outlet to block the connection between the drainage pipe and the coating machine body, thereby facilitating the drying process of the coating machine body after cleaning.

[0004] To achieve the above-mentioned purpose, the utility model provides a water collection pan for a coating machine provided with a flat-bottom valve structure, including a water collection pan arranged on a coating machine body, a drain outlet arranged on the water collection pan, a drain pipe arranged below the water collection pan, and an upper end of the drain pipe is fixedly connected with the drain outlet, a cylinder is arranged below the drain pipe, a piston rod of the cylinder penetrates into the drain pipe and extends upward, a sealing cover for sealing the drain outlet is fixedly arranged on the upper end of the piston rod, and when the sealing cover is lifted up as the piston rod extends upward, the drain outlet is opened.

[0005] The beneficial effect of the utility model is that: with the above structure, the piston rod is extended, and the sealing cover rises accordingly, so that the drain outlet is opened; the piston rod moves downward, and the sealing cover forms a seal for the drain outlet, that is, it forms a closure for the drain outlet, so that the sealing cover is driven to rise and fall by the cylinder to realize the opening or closing of the drain outlet. Such a structural setting can drain water smoothly and without residue when opened, and can effectively block the connection between the drainage pipe and the coating machine body when closed, so as to facilitate the drying treatment of the coating machine body after cleaning.

[0006] The utility model can be further configured to have a fixed sleeve fixedly arranged between the upper port and the drain outlet of the drainage pipe, and a cone portion with a width at the top and a narrowness at the bottom is formed on the inner ring surface of the fixed sleeve, and the sealing cover is a conical structure that forms a sealing match with the cone portion. This configuration not only has a good sealing effect, but also facilitates the lifting and lowering of the sealing cover, and is also helpful for drainage. A mounting block that forms a seal for the lower port of the drainage pipe is fixedly arranged, and an outer sleeve extending upward is fixedly arranged on the mounting block. The cylinder is fixedly mounted on the mounting block, and the piston rod of the cylinder is correspondingly located in the outer sleeve. When the sealing cover forms a sealing match with the cone portion of the fixed sleeve, the sealing cover and the outer sleeve form an axial abutment, and the drainage pipe is correspondingly provided with water outlets on both sides of the outer sleeve. In this configuration, when the sealing cover seals the drain outlet, the outer sleeve can also form a supporting effect on the sealing cover, thereby making the overall structure more stable and reliable. At the same time, the setting of the outer sleeve also forms an effective protection for the piston rod part and provides a guiding support effect.

[0007] The utility model can also be further configured such that the upper end of the fixed sleeve is welded flush with the drain port, and the upper end of the fixed sleeve is recessed downward to form a guide port, the guide port is located above the conical portion and is connected to the conical portion. By providing the guide port, it is more conducive to the smooth discharge of the cleaning water. The lower end of the fixed sleeve is provided with a protrusion extending downward, the protrusion is inserted into the upper port of the drainage pipe, and the upper port of the drainage pipe forms an axial abutment with the lower end face of the fixed sleeve and is fixed by welding. This configuration allows a better connection and fixation between the fixed sleeve and the drainage pipe.

[0008] The utility model can further be configured such that a sealing ring is fixedly arranged on the conical surface of the sealing cover and forms a sealing match with the conical portion of the fixing sleeve. This configuration can further improve the sealing effect between the sealing cover and the conical portion of the fixing sleeve. A sealing sleeve is arranged at the upper end of the outer sleeve and forms a sealing match with the piston rod. This configuration can form a good seal between the outer sleeve and the piston rod.

[0009] The utility model can be further arranged that a mounting plate is fixedly arranged on the cylinder, and the mounting plate is fixed to the mounting block by bolts. Such arrangement has a simple structure and is convenient for assembly and disassembly. BRIEF DESCRIPTION OF THE DRAWINGS
