Specific implementation manners

[0014] In order to make the purpose, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0015] The embodiment of the present utility model provides a hot forming mechanism for pillow core production, including a hot air box 1 and a hot air assembly 2 for supplying hot air into the hot air box 1. Feeding ports and discharging ports are respectively arranged on the front and rear sides of the hot air box 1. An upper conveyor belt 3 and a lower conveyor belt 4 are respectively installed above and below the inside of the hot air box 1. The bottom of the front end of the upper conveyor belt 3 is inclined downward along the front-to-rear direction. The bottom of the rear end of the upper conveyor belt 3 and the lower conveyor belt 4 are horizontally arranged, so that the gap size between the front ends of the upper conveyor belt 3 and the lower conveyor belt 4 gradually decreases along the front-to-rear direction. At the same time, the gap size between the rear ends of the upper conveyor belt 3 and the lower conveyor belt 4 is equal along the front-to-rear direction. The cotton wadding can enter from between the front ends of the lower conveyor belt 3 and the lower conveyor belt 4. When the cotton wadding is conveyed from between the front ends of the upper conveyor belt 3 and the lower conveyor belt 4 to between the rear ends of the upper conveyor belt 3 and the lower conveyor belt 4, the upper conveyor belt 3 and the lower conveyor belt 4 can extrude the cotton wadding. At the same time, the hot air assembly 2 can supply hot air into the hot air box 1, so that the cotton wadding can be hot pressed into shape. Compared with the existing method of manually putting the cotton wadding into the mold for hot pressing, the forming efficiency is high and the labor cost is low at the same time.

[0016] In this embodiment, a left guide plate 5 and a right guide plate 6 are respectively arranged on the left and right sides between the upper conveyor belt 3 and the lower conveyor belt 4. The gap size between the front ends of the left guide plate 5 and the right guide plate 6 gradually decreases along the front-to-rear direction. The gap size between the rear ends of the left guide plate 5 and the right guide plate 6 is equal along the front-to-rear direction, so as to hot press the cotton wadding into a certain width.

[0017] It should be noted that the distance between the upper conveyor belt 3 and the lower conveyor belt 4 is adjustable, and the distance between the left guide plate 5 and the right guide plate 6 is adjustable. Therefore, the thickness and width of the cotton wadding can be adjusted.

[0018] In this embodiment, the hot air assembly 2 includes a heating device 21 and a blower 22. The heating device 21 is installed inside the upper conveyor belt 3. The exhaust duct of the blower 22 is communicated with the heating device 21. The air blown out by the blower 22 can enter the heating device 21. At the same time, the upper conveyor belt 3 is provided with second ventilation holes 31. The hot air can pass through the upper conveyor belt 3 and enter between the upper conveyor belt 3 and the lower conveyor belt 4 to heat and shape the cotton wadding. At the same time, the intake duct of the blower 22 is arranged inside the lower conveyor belt 4. The lower conveyor belt 4 is provided with third ventilation holes 41. The hot air between the upper conveyor belt 3 and the lower conveyor belt 4 can pass through the lower conveyor belt 4 and enter the inside of the lower conveyor belt 4. The hot air inside the lower conveyor belt 4 can flow back to the blower 22 through the intake duct of the blower 22. The heating effect is good, and at the same time, it can also make the hot air circulate, saving energy and protecting the environment.

[0019] Specific principle: During use, the cotton wadding can enter between the front ends of the lower conveyor belt 3 and the lower conveyor belt 4. When the cotton wadding is conveyed from between the front ends of the upper conveyor belt 3 and the lower conveyor belt 4 to between the rear ends of the upper conveyor belt 3 and the lower conveyor belt 4, the upper conveyor belt 3 and the lower conveyor belt 4 can squeeze the upper and lower sides of the cotton, and the left guide plate 5 and the right guide plate 6 can squeeze the left and right sides of the cotton wadding. At the same time, the hot air assembly 2 can supply hot air into the hot air box 1, so as to hot-press and form the cotton wadding.

[0020] The specific implementation manners of the present utility model described above do not constitute a limitation to the protection scope of the present utility model. Any other corresponding changes and deformations made according to the technical concept of the present utility model shall be included in the protection scope of the claims of the present utility model.
