Uniform air supply structure of cast tape machine

Abstract

The utility model provides a uniform air supply structure for a casting machine, which solves the problem that the hot air blown out by the current heating box cannot act evenly on the liquid film. It also includes a No. 1 air guide plate, which is evenly distributed below the heating tube along the width direction of the box; an adjusting rod, one end of which is connected to the No. 1 air guide plate, and the other end is located outside the box; a mounting block, which is arranged on the outside of the box, and the mounting block is provided with a No. 1 through hole for cooperating with the adjusting rod; a locking piece, which is arranged on the mounting block and is used to lock the adjusting rod. The angle of the No. 1 air guide plate is adjusted by rotating each adjusting rod, and the adjusting rod is locked by the locking piece after the adjustment is completed. After the heated air passes through the No. 1 air guide plate, the hot air is evenly distributed within the same horizontal width of the box, and then flows out evenly from the air outlet, ensuring that the temperature of the liquid film at the same width is almost the same at various locations, thereby effectively improving the quality of the film.

Description

Technical Field

[0001] The utility model relates to the technical field of tape casting machines, in particular to a uniform air supply structure of a tape casting machine. Background Art

[0002] Casting machine is a machine for making thin film. Its working principle is to form a liquid film on the steel belt by casting the solution. Clean air passes through the heating box. After being heated by the heating box, the air is blown out from the bottom of the box to act on the liquid film. The hot air evaporates the solvent to form a thin film. Therefore, the quality of the hot air affects the volatilization of the solvent in the liquid film, and the volatilization of the solvent directly affects the quality of the film. At present, after the hot air is blown out from the heating box of the casting machine, it cannot act evenly on the liquid film, resulting in a large temperature difference at different places of the liquid film with the same width, which in turn affects the quality of the film.

DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0023] In the embodiment, Figure 1 , Figure 2 As shown, the uniform air supply structure of the casting machine includes a box body 1 and a heating pipe 2 arranged in the box body 1, the upper end of the box body 1 is provided with an air inlet 3, the lower end is provided with an air outlet 4, and also includes:

[0024] A first air guide plate 5 is evenly distributed below the heating tube 2 along the width direction of the box body 1;

[0025] An adjusting rod 6, one end of which is connected to the first air guide plate 5, and the other end of which is located outside the box body 1;

[0026] A mounting block 7, arranged on the outside of the box body 1, wherein the mounting block 7 is provided with a through hole 8 for cooperating with the adjusting rod 6;

[0027] The locking member 9 is arranged on the mounting block 7 and is used for locking the adjusting rod 6 .

[0028] The heating tubes 2 are evenly arranged along the width direction of the box body 1, and the distance between adjacent No. 1 air guide plates 5 is 70-90 mm. The angle of the No. 1 air guide plate 5 is adjusted by rotating each adjusting rod 6. After the adjustment, the adjusting rod 6 is locked by the locking member 9. When the heated air passes through the No. 1 air guide plate 5, the hot air is evenly distributed within the same horizontal width of the box body 1, and then flows out evenly from the air outlet 4, ensuring that the temperature of the liquid film at the same width is almost the same, thereby effectively improving the quality of the film.

[0029] In the embodiment, Figure 2 As shown, a notch 10 for communicating with the through hole 8 is provided on one side of the mounting block 7, and the locking member 9 is a bolt, which passes through the notch 10. By loosening or tightening the bolt, the through hole 8 becomes larger or smaller, and the adjusting rod 8 can be rotated or clamped, which is convenient for adjustment.

[0030] In the embodiment, Figure 3 As shown, a partition 11 is provided between the heating tube 2 and the first air guide plate 5, and the partition 11 is evenly distributed with second through holes 12. Part of the air flows out from the second through holes 12, and part of the air stays in the heating tube 2, which increases the time the air stays in the heating tube 2 and heats the air better.

[0031] In the embodiment, Figure 1 As shown, a second air guide plate 13 is provided above the heating tube 2, and the angle of the second air guide plate 13 is adjustable. The second air guide plate 13 is also adjusted by the adjustment rod 6 to allow air to evenly act on each position of the heating tube 2 to ensure uniform heating of the air.

[0032] In the embodiment, Figure 1 As shown, the heating tube 2 is provided with a No. 1 air duct 14 and a No. 2 air duct 15 in sequence above the heating tube 2, the width of the No. 1 air duct 14 is greater than the width of the No. 2 air duct 15, a transition air duct 16 is provided between the No. 1 air duct 14 and the No. 2 air duct 15, the No. 2 air guide plate 13 is arranged in the No. 2 air duct 15, and the transition air duct 16 is provided with a No. 3 air guide plate 17. When the air enters the heating tube 2, the flow rate slows down, and at the same time, through the cooperation of the No. 2 air guide plate 13 and the No. 3 air guide plate 17, the air is evenly acted on all parts of the heating tube 2, and the air is evenly heated.

[0033] In the embodiment, Figure 1 As shown, the air outlet 4 is arranged on the side of the box body 1, and the side of the box body 1 away from the air outlet 4 is inclined. The hot air is blown out horizontally from the air outlet 4, which will not affect the surface of the liquid film, thereby ensuring the quality of the film.

[0034] The first air guide plate 5 is made of stainless steel. Of course, the second and third air guide plates are all made of stainless steel to ensure that each air guide plate has good strength and is not easy to deform, to ensure the air guide effect and the air guide plate is not easy to rust, and to ensure that the hot air blown out is clean.

[0035] Obviously, the above embodiments of the present invention are merely examples for illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to provide all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still fall within the scope of protection of the present invention.
