AI Technical Summary
The vertical lifting structure of existing rotary screen printing machines prevents the squeegee from directly contacting the inner wall of the rotary screen, affecting the squeegee effect.
An electric push rod drives the rotating frame to move downwards, ensuring that the scraper can contact the inner wall of the circular mesh. A fixed structure stabilizes the position of the electric push rod to prevent wobbling.
This ensures effective squeegee application, guaranteeing that the squeegee can effectively contact the inner wall of the rotary screen as it descends, thus improving printing quality.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotary screen printing machine technology, and in particular to an improved structure of a rotary screen printing machine. Background Technology
[0002] Rotary screen printing machines use a continuously rotating, seamless cylindrical screen for printing. Based on the arrangement of the screen, they can be divided into three types: vertical, horizontal, and radial. The most commonly used is the horizontal rotary screen printing machine. Rotary screen printing machines are often used in combination with other units in a single unit.
[0003] Rotary screen printing machines typically employ a lifting structure, which raises and lowers the rotary screen. The lifting structure descends to bring the rotary screen into contact with the fabric for printing. When the rotary screen is not in operation, it can also be raised to avoid direct contact with the printing guide belt, thus preventing contamination of the guide belt.
[0004] Existing rotary screen printing machines typically employ a vertical lifting structure. When the rotary screen descends, the squeegee on the center roller cannot directly contact the inner wall of the rotary screen, thus affecting the squeegee effect. Utility Model Content
[0005] The purpose of this invention is to provide an improved structure for a rotary screen printing machine.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an improved structure of a rotary screen printing machine, including a base located at both ends, two fixed platforms located on both sides of the base, a protrusion provided on one of the fixed platforms, a rotating frame rotatably mounted on the protrusion, a mounting groove provided on the rotating frame, and an electric push rod provided on the base, the end of the electric push rod abutting against the bottom of the rotating frame.
[0007] A further feature is provided: a fixed arc ring is provided on the rotating frame.
[0008] The configuration is further defined as follows: a rotating ring is provided at the front end of the rotating frame, and a rotating shaft is provided at the end of the electric push rod that passes through the rotating ring; the electric push rod is inclined.
[0009] The base is further configured such that: a fixed seat is provided on the base, a crossbar is provided on the fixed seat, a rotating rod is provided on the rotating shaft, a fixing hole is provided at the end of the rotating rod through the crossbar, and a fixing nut is provided at the end of the crossbar.
[0010] In summary, the present invention has the following beneficial effects: the improved structure of the rotary screen printing machine can drive the rotating frame to move downward after the rotary screen descends via an electric push rod, ensuring that the squeegee can contact the inner wall of the rotary screen, thereby ensuring the squeegee effect.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings.
[0014] An improved structure for a rotary screen printing machine includes a base 1, with one base 1 located at each end. A fixed platform 2 is located on each side of the base 1, and the two fixed platforms 2 are at the same height.
[0015] One of the fixed platforms 2 is provided with a protrusion 3 facing the other fixed platform 2. A rotating frame 4 is rotatably provided on the protrusion 3. A support groove 5 is provided on the rotating frame 4. A fixing arc ring 7 is provided on the support groove 5. The center roller is fixed on the support groove 5 through the fixing arc ring 7.
[0016] An inclined electric push rod 6 is mounted on the base 1. A rotating shaft 9 is located at the front end of the electric push rod 6. A rotating ring 8 is located at the front end of the rotating frame 4, and the rotating shaft 9 passes through the rotating ring 8. When the electric push rod 6 retracts, it can pull the rotating frame 4 downward, thereby causing the central roller to descend and the scraper to contact the inner wall of the circular mesh.
[0017] A fixed seat 10 is provided on the base 1, and a crossbar 11 is provided on the fixed seat 10. A downward rotating rod 12 is provided on the rotating shaft 9. The end of the rotating rod 12 is provided with a fixing hole 13 passing through the crossbar 11, and the end of the crossbar 11 is provided with a fixing nut 14. By restricting the rotating rod 12 with the fixing nut 14, the column electric push rod 6 can be fixed, thereby forming a structurally stable triangle below, ensuring that the electric push rod 6 will not wobble under the action of the central roller.
[0018] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
