Description

Technical Field

[0001] This application relates to the field of painting apparatus, and more specifically, to an apparatus for applying primer to tinplate printing. Background Technology

[0002] Tinplate, also known as tin-plated iron, is a common name for electroplated tin-coated thin steel sheets, abbreviated as SPTE. It refers to cold-rolled low-carbon thin steel sheets or strips plated with commercially pure tin on both sides. This material combines the strength and formability of steel with the corrosion resistance, solderability, and aesthetic appearance of tin, possessing characteristics such as corrosion resistance, non-toxicity, high strength, and good ductility.

[0003] Since it is an electroplated tin sheet, the electroplated tin sheet is relatively smooth during production. Therefore, directly spraying the primer onto the surface of the electroplated tin sheet will reduce the adhesion of the primer, and after long-term use, the primer will peel off. Utility Model Content

[0004] To overcome the above shortcomings, this application provides a tinplate printing primer application device, which aims to improve the problem that directly spraying primer onto the surface of electroplated tin-plated thin steel plate will reduce the adhesion of the primer and cause it to peel off after long-term use.

[0005] This application provides a tinplate printing primer coating device, including a conveyor and a grinding assembly. A downward pressure roller is provided on one side of the upper part of the conveyor. The grinding assembly includes a transverse grinding component, a longitudinal grinding component, a paint supply component, a paint spray head, and a drying component. The grinding end of the transverse grinding component is transversely reciprocatingly slidably connected to the upper part of the conveyor. The grinding end of the longitudinal grinding component is longitudinally reciprocatingly slidably connected to the upper part of the conveyor. The paint supply component is located on one side of the conveyor. The paint spray head is fixedly connected to the upper part of the other side of the conveyor. The drying end of the drying component is located on the upper part of the conveyor's discharge end.

[0006] In one specific implementation, the outer surface of the pressure roller is provided with a soft layer, and the soft layer is made of an anti-slip material.

[0007] In one specific implementation, the transverse grinding component includes a first motor, a first connecting rod, a first reciprocating frame, and a first disc. The first reciprocating frame is slidably connected to the conveyor, the first motor is fixedly connected to the upper part of the conveyor, the first disc is rotatably connected to the upper part of the conveyor, the output end of the first motor is fixedly connected to the first disc, one side of the first disc is rotatably connected to one end of the first connecting rod, and the other end of the first connecting rod is rotatably connected to the first reciprocating frame.

[0008] In one specific implementation, the longitudinal grinding component includes a second motor, a second connecting rod, a second reciprocating frame, and a second disc. The second reciprocating frame is slidably connected to the conveyor. The second motor is fixedly connected to one side of the conveyor. The second disc is rotatably connected to one side of the conveyor. The output end of the second motor is fixedly connected to the second disc. One side of the second disc is rotatably connected to one end of the second connecting rod. The other end of the second connecting rod is rotatably connected to the second reciprocating frame.

[0009] In one specific implementation, a grinding pad is provided at the bottom of both the first reciprocating frame and the second reciprocating frame, and a fixing plate is symmetrically provided on both the first reciprocating frame and the second reciprocating frame, and the grinding pad is fixed by the fixing plate.

[0010] In one specific implementation, the paint supply unit includes a paint pump and a paint bucket, the paint pump is connected to the paint bucket, and the output end of the paint pump is connected to the paint spray head.

[0011] In one specific implementation, the drying component includes a fan, a heating chamber, and a blower head. The output end of the fan is connected to one side of the heating chamber, and the other side of the heating chamber is connected to the blower head. The blower head is fixedly connected to the upper part of one side of the conveyor.

[0012] In one specific implementation, the blower output end is provided with a three-way pipe, one end of which is connected to one side of the heating box, and the other end of which is provided with a dust blowing head, which is fixedly connected to the conveyor on the side near the longitudinal grinding component.

[0013] Beneficial Effects: This application provides a tinplate printing primer coating device. In use, one side of an electroplated tin sheet is placed on the feed end of a conveyor. Under the pressure of the soft roller, the conveyor transports the electroplated tin sheet. When the electroplated tin sheet is transported below the transverse and longitudinal grinding components, the grinding end of the transverse grinding component performs transverse reciprocating friction on the surface of the electroplated tin sheet, and the grinding end of the longitudinal grinding component performs longitudinal reciprocating friction on the surface of the electroplated tin sheet. This alternating horizontal and vertical friction leaves slight marks on the surface of the electroplated tin sheet. The traces are created by the continuous conveyor transporting the tin-plated steel sheet to the bottom of the spray head. The paint supply unit then delivers the primer into the spray head, which sprays the primer onto the surface of the tin-plated steel sheet. The continuous conveyor transports the primer-coated tin-plated steel sheet to the drying end of the drying unit, where it dries the sheet. Throughout the process, the surface of the tin-plated steel sheet is rubbed horizontally and vertically, leaving traces and increasing the adhesion between the primer and the tin-plated steel sheet. This reduces primer peeling even after prolonged use. Attached Figure Description

This alternating horizontal and vertical friction leaves slight marks on the surface of the electroplated tin sheet. After the conveyor 100 continuously conveys the tin-plated thin steel sheet, the sheet reaches below the spray head 240. The paint supply unit 230 delivers the primer into the spray head 240, which then sprays the primer onto the surface of the sheet. The continuous conveyor 100 transports the primer-coated sheet to the drying end of the drying unit 250, where it dries the sheet. Throughout the process, the sheet is rubbed horizontally and vertically to create marks, increasing the adhesion between the primer and the sheet. This reduces primer detachment even after prolonged use.
