Description

Technical fields:

[0001] This utility model relates to the technical field of prop surface treatment, and more specifically to a rotary spraying table for rapid hardening of foam prop surfaces. Background technology:

[0002] Foam is a material used in the production of some film and television props. For example, if a stone lion is needed for a film or television performance scene, the lion's shape can be made of foam, and then surface treatment can be used to make the foam lion's exterior resemble the stone lion's exterior. Surface hardening is a crucial step in processing foam props. Currently, there are several methods for surface hardening: 1. Simple hardening: A layer of water-based putty or quick-drying plaster is evenly applied to the surface of the foam prop, and then sanded after drying; 2. Resin hardening: The surface of the foam prop is coated with polyester resin or epoxy resin, and then treated with a glass-like hardening process; 3. Polyurea spraying: Polyurea material is directly sprayed onto the surface of the foam prop using polyurea spraying equipment, forming a uniform, smooth, elastic protective layer within seconds. Compared to putty, quick-drying plaster, and resin, polyurea spraying is more convenient and faster. However, current polyurea spraying involves manual application using a handheld spray gun or spray head, which is physically demanding. Therefore, a workbench that can be set up to assist with polyurea spraying of foam props is needed to reduce the workload for workers. Utility Model Content:

The driving pulley is fixed to the rotating shaft of the motor 611. The motor 611 is fixed to the base plate 1 through the motor bracket 612.

[0026] A cylindrical protective cover 8 is fitted onto the rotating support platform 2, and the lower end of the protective cover 8 is fixed to the base plate 1. A spray head for spraying is installed on the spray head clamp 3. The spray head sprays polyurea onto the foam prop set on the rotating support platform 2. The protective cover 8 can activate its protective function to prevent the sprayed polyurea from splashing.

[0027] The protective cover 8 has an inlet / outlet slot 81 on the front and a vertical spraying slot 82 on the rear, which is directly opposite the spray head clamp 3. The inlet / outlet slot 81 is a window for taking out and putting in foam props, and an arc-shaped protective door can be installed through the window via a hinge.

When a foam prop is placed, the foam prop presses down on the tray 71, so that the positioning pin 27 is inserted into the foam prop. The weight of the foam prop and the friction between it and the positioning pin 27 can overcome the force of the spring 73 and prevent the tray 71 from returning to its original position.

[0033] The central axis of the tray 71 and the central axis of the rotating disk 21 are on the same straight line, and the diameter of the tray 71 is smaller than the diameter of the rotating disk 21.

The foam props are positioned by inserting them into the positioning pins 27. At the same time, the spraying device for spraying polyurea material is clamped in the spraying head clamp 3.

[0035] Then start the motor 611 on the power actuator 6. Through belt drive, the outer gear ring 23 and the drive disk 51 can be rotated. The rotation of the outer gear ring 23 can drive the rotating support platform 2 to rotate, that is, the foam prop can be rotated. The rotation of the drive disk 51 can drive the spray head clamp 3 to move up and down on the guide column 4. Then turn on the polyurea spraying equipment to realize automatic spraying.
