DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] See also Figure 1 The utility model provides a plywood hot pressing and cooling device, comprising a main box body 1, a movable frame arranged inside for movement, an internal hot pressing component, and an air cooler 2 arranged at the lower end for cooling, so as to realize the hot pressing and cooling of the plywood.

[0030] See also Figure 1-Figure 4 The mobile frame is arranged inside the main box body 1, and a top plate 6 is arranged on the upper end of the mobile frame. A first electric push rod 8 is installed on the top of the main box body 1. The output end of the first electric push rod 8 passes through the main box body 1 and is connected to the top plate 6. The top plate 6 is pushed by the first electric push rod 8 to realize the up and down movement of the mobile frame, which is convenient for pushing the plywood downward to the lower part of the main box body 1 for cooling after hot pressing. The two sides of the lower end of the top plate 6 are connected with connecting shafts 7, and the bottom end of the connecting shaft 7 is connected with the bottom plate 5, so that the top plate 6, the connecting shaft 7 and the bottom plate 5 move downward as a whole. A hot pressing component is installed inside the mobile frame for hot pressing work. The connecting shafts 7 are symmetrically arranged in pairs on the outer side between the bottom plate 5 and the top plate 6, so that the connecting shafts 7 are arranged at the four end positions between the top plate 6 and the bottom plate 5, thereby making the stability between the top plate 6 and the bottom plate 5 higher. When the first electric push rod 8 pulls the top plate 6 to the uppermost end, the bottom plate 5 is at the lower end of the feed port 17, thereby reducing the discharge of cold air from the lower end, and the top plate 6 is closely connected to the inner wall of the main box body 1. Through the top plate 6, when the plywood is in the lower cold air, the top plate 6 blocks the upper end, so that the cold air can cool the plywood completely, so that the cooling effect is better.

[0031] The hot pressing assembly includes a multi-layer hot pressing plate 12 arranged inside the connecting shaft 7 so that it can perform hot pressing work on multiple plywoods, thereby speeding up the work efficiency. The hot pressing plate 12 is connected to side plates 13 on both sides. The side plates 13 are provided with movable holes 14 on both sides to connect with the connecting shaft 7, so that the hot pressing plate 12 moves up and down in the connecting shaft 7 when subjected to force, and there will be no problem of offset, so that the temperature effect during hot pressing is better. A plurality of telescopic rods 16 are provided between the upper and lower ends of the side plates 13, and a spring 15 is provided on the outer side of the telescopic rod 16 so that the spring 15 at the lower end can be used to press the plywood. After the push plate 11 pushes the hot pressing plate 12 for hot pressing, the hot pressing plate 12 can be pushed apart and the hot pressing plate 12 can be pulled down to avoid all of them piling up downward. The lower end of the bottom plate 5 is connected to the mounting frame 9, and the second electric push rod 10 is installed inside the mounting frame 9. The push plate 11 is installed at the lower end of the hot pressing plate 12, and the output end of the second electric push rod 10 passes through the bottom plate 5 and is connected with the push plate 11. The push plate 11 is pushed by the second electric push rod 10 to push the hot pressing plate 12 upward so that the hot pressing plate 12 performs hot pressing on the plywood.

[0032] A cooler 2 is installed on one side of the lower part of the main box body 1, and the air supply end of the cooler 2 passes through the lower part of the main box body 1, so that the cavity in the lower part of the main box body 1 is continuously supplied with cold air through the cooler 2, so that the cooling performance inside the cavity is high, and the cooling efficiency is low when starting the cooling during cooling, so as to achieve the purpose of high efficiency. An air outlet is set on the other side of the lower part of the main box body 1, and an exhaust fan 3 is installed inside the air outlet, so that the cold air is discharged and the cold air is supplied again after it is no longer cold. A temperature sensor 4 is installed at the lower end of the main box body 1 to facilitate the sensing of the internal temperature, so that the cold air supply is convenient and timely.

[0033] See also Figure 5 A feed port 17 is provided on the upper front end of the main box body 1 to facilitate placing the plywood between the hot pressing plates 12 for hot pressing. A control panel 18 is installed on the outside of the main box body 1 to facilitate the staff to operate the device.

[0034] Working principle: When in use, first connect the air cooler 2, the exhaust fan 3, the temperature sensor 4, the first electric push rod 8, the second electric push rod 10, the hot pressing plate 12 and the control panel 18 to an external power supply, put the plywood between the hot pressing plates 12 through the feed port 17, and then the second electric push rod 10 pushes the push plate 11 to push the hot pressing plate 12 upward to compress the spring 15 and the telescopic rod 16 to perform hot pressing on the plywood. After hot pressing, the second electric push rod 10 loosens the push plate 11, and the hot pressing plate 12 separates under the action of the spring 15. Then the first electric push rod 8 pushes the top plate 6 so that the hot pressing plate 12 at the lower end all enters the lower end of the main box body 1, and the plywood is quickly cooled under the continuous cooling action of the air cooler 2 at the lower end to complete the work.
