[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a heating device for a foam molding machine of the utility model in conjunction with the accompanying drawings.

[0023] like Figure 1-6 As shown, a heating device for a foam molding machine includes a box body 1, a heating box 5 is installed at the bottom of the box body 1, a cleaning box 4 is installed on the top of the heating box 5, a processing layer 3 is arranged on the top of the cleaning box 4, and a filtering device is arranged on the side wall of the processing layer 3.

[0024] In this embodiment, the heating box 5 is connected to the processing layer 3 through the jet pipe 13, and the mold plate 6 is set at the bottom of the processing layer 3. The mold plate 6 and the bottom of the processing layer 3 are detachably connected to adapt to the mold processing of different products. After the heating box 5 is heated, the hot steam is brought to the processing through the jet pipe 13 to heat and shape the mold plate 6.

[0025] In this embodiment, the filtering device includes an air intake pipe 7, which is connected to an exhaust fan 8. The exhaust fan 8 puts excess hot steam into a filter box 11 through an air inlet pipe 9. A filter layer 10 is also provided in the filter box 11. The hot steam is filtered by the filter box 11 and then discharged from an air outlet pipe 12. The end of the air outlet pipe 12 away from the filter layer 11 is connected to an air jet pipe 13. The filtered hot steam is discharged to the processing layer 3 through the air jet pipe 13 for recycling, thereby saving energy.

[0026] In this embodiment, the filter layer 10 is provided with activated carbon filter cotton 18, glass fiber filter cotton 19 and synthetic fiber filter cotton 20 in order from top to bottom. The three types of filter cotton are used to filter the excess hot steam after processing the mold, so that the odor in the hot steam is removed.

[0027] In this embodiment, the cleaning box 4 is used to hold garbage generated during the mold processing process. A movable plate 15 is arranged on the rear side of the cleaning box 4. The movable plate 15 is slidably connected to the left and right side plates of the cleaning box 4. The movable plate 15 is fixedly connected to the hydraulic cylinder 14 behind it. The hydraulic cylinder 14 is used to push the movable plate 15 to move horizontally. Limiting blocks 16 are arranged at the ends of the left and right side plates of the cleaning box 4. The limiting blocks 16 are used to limit the movable plate 15. A scraper strip 17 is arranged at the bottom of the movable plate 15. The scraper strip 17 is used to remove garbage on the movable plate 15.

[0028] The working principle of a heating device for a foam forming machine provided by the utility model is as follows:

[0029] The water tank 5 is heated by the control panel 2 to generate hot steam, and the hot steam enters the processing layer 3 through the paint spraying pipe 13 to heat and shape the mold plate 6 in the processing layer 3. After the mold shaping is completed, there will be excess hot steam in the processing layer 3. By starting the exhaust fan 8, the excess hot steam is sucked from the suction pipe 7, and then the hot steam is transported to the filter box 11 through the air inlet pipe 9. The filter layer 10 removes the odor in the hot steam, and then the filtered hot steam is transported to the jet pipe 13 through the air outlet pipe 12. The jet pipe 13 then passes the hot steam to the air outlet pipe 12. The cleaning box 4 is transported to the processing layer 3 for use in mold processing; the left and right side plates of the cleaning box 4 are slidably connected to the moving plate 15, and a hydraulic cylinder 14 is arranged behind the moving plate 15. When the garbage in the cleaning box 4 needs to be cleared, the hydraulic cylinder 14 is started to push the moving plate 15 forward to clean the hard-to-clean garbage on the bottom of the cleaning box 4 and the left and right side plates, and limit blocks 16 are also arranged at the ends of the left and right side plates to limit the moving plate 15, and the garbage on the moving plate 15 is scraped off by the scraper strip 17 at the bottom of the moving plate 15.

[0030] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
