Description

Technical Field

[0001] The utility model relates to the technical field of foam board production and processing, in particular to steam shaping equipment for EPS foam board processing and molding. Background Art

[0002] EPS foam board is a lightweight material with good thermal insulation performance, which is widely used in construction, packaging, refrigeration and other industries. However, during the processing of EPS foam board, due to its material characteristics, it is easy to deform after molding, which affects the product quality. Therefore, equipment that can effectively shape EPS foam board is needed.

[0003] In the prior art, after searching, it was found that a Chinese patent disclosed a steam shaping device for the production and molding of EPS foam boards, and its application number is 201921561589.7. The patent mainly includes a base, a first water storage tank is installed on the upper left end of the base, a first pipe is installed obliquely on the right side of the heating box, a second pipe is installed obliquely on the lower side of the first pipe and the upper right end of the water inlet bucket, the first pipe and the second pipe are connected, the heating box and the water inlet bucket are connected through the first pipe and the second pipe, and a solar panel is installed on the upper right end of the base. Although the above utility model has a simple structure and is easy to use, the cold water circulating in the condensation box condenses the hot steam in the first pipe and the second pipe into water droplets, and the water falls into the water inlet bucket on the lower side and enters the first water storage tank on the lower side, so that the hot steam is quickly condensed into water, saving water resources. However, the steam enters from one side of the bottom of the heating box and is discharged from the other side of the heating box. The steam is partially blocked by the internal partition, which limits the flow path of the steam in the box. The steam is easily unevenly distributed inside the heating box, especially at the position above the entrance and far away from the exit, which affects the uniform heating and shaping effect of the board. Moreover, this discharge method may cause part of the steam to be discharged before being fully utilized after passing through the partition, which not only reduces the utilization efficiency of the steam, but also increases the energy consumed by the subsequent condenser, water inlet pump and water outlet pump for continuous operation. Therefore, those skilled in the art provide a steam shaping device for EPS foam board processing and molding to solve the problems raised in the above background technology. Utility Model Content

A steam generator 5 is provided on one side of the setting box 1, wherein the connecting pipe 2 close to the steam generator 5 is connected to the steam generator 5 through a connecting pipe 6, and a pressure reducing valve 11 is provided on the top of the setting box 1. Specifically, the EPS foam board to be steam-set is fixed in the setting box 1 through the fixing components, and the plurality of fixing components provided can realize the fixing work of a plurality of EPS foam boards to improve production efficiency. As a steam-generating device, the steam generator 5 can use fuel or other energy sources to heat water into steam. The steam is transported to the inside of the connecting pipe 2 through the connecting pipe 6 and then continuously flows to the inside of the steam transmission pipe 3. The steam is sprayed to the EPS foam board through the steam nozzle 4. The steam nozzles 4 evenly arranged at the bottom of the EPS foam board can make each EPS foam board evenly contact with the steam, so that the EPS foam board maintains a stable shape under the action of the steam. When the steam continues to flow inside the setting box 1, the steam pressure inside the setting box 1 can be adjusted under the action of the pressure reducing valve 11, ensuring that the inside of the setting box 1 is always in a stable working state.

The fixing plate 7 is fixedly connected to the rear side of the inner wall of the shaping box 1. The clamping assembly includes two symmetrically arranged clamping plates 8, four springs 9 and two inclined portions 10. The springs 9 adjacent to each of the two springs 9 are installed between the corresponding clamping plates 8 and the inner wall of the fixing plate 7. The two inclined portions 10 are arranged on the front side of the corresponding clamping plates 8. A supporting plate 16 is fixedly provided on the inner wall of the shaping box 1 close to the box door 17 and flush with the bottom of the fixing plate 7. The supporting plate 16 can provide good support for the side of the EPS foam board away from the clamping. Specifically, the EPS foam board is inserted between the two clamping plates 8.

[0026] Working principle:

[0027] The EPS foam board to be steam-set is inserted between the two clamping plates 8. During the insertion, the clamping plates 8 can be pushed to move apart under the action of the inclined surface 10. When the EPS foam board is inserted between the two clamping plates 8, the clamping plates 8 can be closely attached to the outer side of the EPS foam board under the action of the spring 9, thereby realizing the rapid fixing operation of the EPS foam board;

[0028] The steam produced by the steam generator 5 is transported to the inside of the connecting pipe 2 through the connecting pipe 6 and then continuously flows to the inside of the steam transmission pipe 3. The steam is sprayed to the EPS foam board through the steam nozzle 4. The steam nozzles 4 evenly arranged at the bottom of the EPS foam board can make each EPS foam board contact with the steam evenly, so that the EPS foam board maintains a stable shape under the action of the steam. When the steam continues to flow inside the shaping box 1, the steam pressure inside the shaping box 1 can be adjusted under the action of the pressure reducing valve 11, ensuring that the inside of the shaping box 1 is always in a stable working state;

[0029] When the EPS foam board is shaped, the control valve 13 is opened to pass the residual steam in the shaping box 1 into the condenser 14. The condenser 14 condenses the steam into water and discharges it through the drain pipe. The discharged water can be reused to reduce the waste caused by the loss of steam when the door is opened. At the same time, it can reduce the energy consumption caused by the continuous operation of the condenser 14, which is highly practical.
