DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0022] Example 1

[0023] The utility model provides a foam production preheating treatment device, such as Figures 1 to 4As shown, it includes a pre-foaming device 1, the top of the pre-foaming device 1 is fixedly connected with a feed pipe 4, and a sealing ring 15 is provided at the connection between the feed pipe 4 and the pre-foaming device 1 to ensure the air tightness between the feed pipe 4 and the pre-foaming device 1, and a conical barrel 3 is fixedly installed on the top of the feed pipe 4, and a fixed shaft 5 is provided inside the conical barrel 3. A fixed baffle 10 is welded to the outside of the fixed shaft 5, and a circular ring 20 is sleeved and connected to the outside of the fixed shaft 5 at the top position of the fixed baffle 10. A movable plate 11 is fixedly connected to the outside of the circular ring 20, and a bolt 19 is threadedly connected to the middle part of the outer surface of the circular ring 20. By rotating the bolt 19 clockwise, the bolt 19 moves toward the direction of the fixed shaft 5, and then the circular ring 20 is pressed to fix the movable plate 11 in the conical barrel 3, and the top of the fixed shaft 5 is fixedly connected with an L-shaped bracket 16. The L-shaped bracket 16 The end away from the fixed axis 5 is connected to a driving device 17, which is a manual telescopic rod. Driving the driving device 17 can make the L-shaped bracket 16 drive the device inside the conical barrel 3 to move up and down as a whole. The outer wall of the conical barrel 3 is located at the bottom end of the driving device 17 and a fixed bottom plate 18 is welded thereon. The tops of the fixed baffle 10 and the movable plate 11 are both installed with a blocking cloth 7. A closed space is formed between the fixed baffle 10, the movable plate 11, the conical barrel 3 and the blocking cloth 7. Through the action of the blocking cloth 7, the fixed baffle 10 and the movable plate 11 form a closed space in the area enclosed by the interior of the conical barrel 3. A fluidized bed 2 is installed at one end of the pre-foaming device 1, and a movable frame 8 is movably connected to both sides of the top of the fluidized bed 2. A breathable cloth 9 is movably installed on the inner wall of the movable frame 8. The bottom ends of the pre-foaming device 1 and the fluidized bed 2 are both fixedly installed with a support seat 14.

[0024] like Figures 2 to 3 As shown, the interior of the fixed shaft 5 is connected to the rotating shaft 6 through a thread, and a conical stopper 12 is fixedly installed at the bottom end of the rotating shaft 6. The size of the conical stopper 12 is equal to the inner diameter of the feed pipe 4. By controlling the driving device 17, the conical stopper 12 moves downward along the inner wall of the feed pipe 4. Since the conical stopper 12, the feed pipe 4 and the pre-foaming device 1 form a closed space, the pressure generated by the conical stopper 12 during the downward movement causes the foam raw material on the inner wall of the feed pipe 4 to be squeezed into the interior of the pre-foaming device 1.

[0025] like Figures 3 and 4 As shown, a scraper 13 is provided at the bottom end of the conical stopper 12, and the number of the scrapers 13 is set to two. By rotating the rotating shaft 6 inside the fixed shaft 5, the conical stopper 12 can be moved downward on the inner wall of the feed pipe 4. During the process, the two scrapers 13 at the bottom end of the conical stopper 12 clean the foam raw materials adsorbed on the inner wall of the feed pipe 4, thereby cleaning the inner wall of the feed pipe 4.

[0026] Working principle: When using the device, start the driving device 17 to drive the fixed shaft 5 in the conical barrel 3 to move downward, so that the conical stopper 12 blocks the feed pipe 4, and then adjust the position of the movable plate 11 according to the foam raw material to be foamed, turn the bolt 19 clockwise to fix the ring 20 and the movable plate 11 inside the conical barrel 3, add a certain amount of foam raw material into the conical barrel 3, and then drive the driving device 17 to drive the L-shaped bracket 16 to move upward, so that the conical stopper 12 in the conical barrel 3 is separated from the feed pipe 4, so that the foam raw material in the conical barrel 3 enters the interior of the pre-foaming device 1 along the feed pipe 4, and then drive the driving device again. Device 17, so that the conical stopper 12 blocks the feed pipe 4, rotates the rotating shaft 6 inside the fixed shaft 5, and drives the conical stopper 12 at the bottom end of the rotating shaft 6 to move. Since the conical stopper 12, the feed pipe 4 and the pre-foaming device 1 form a closed space, in the process of the conical stopper 12 moving downward along the feed pipe 4, the pressure generated causes the foam raw material on the inner wall of the feed pipe 4 to be squeezed into the interior of the pre-foaming device 1. In the process of the conical stopper 12 moving downward, the scraper 13 at the bottom end of the conical stopper 12 is driven to move along the inner wall of the feed pipe 4, thereby cleaning the inner wall of the feed pipe 4, so that all the foam raw materials in the conical barrel 3 enter the interior of the pre-foaming device 1 for foaming.

[0027] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
