Description

Technical Field

[0001] The present invention relates to the field of foam plastic processing, and particularly relates to a device for processing foam plastics. Background Art

[0002] The processing steps of polyurethane foam plastics generally include plastic batching, molding, machining, joining, and finishing, etc. After the polyurethane foam plastics are molded, they generally have a high temperature and need to be cooled in time to ensure the smoothness of the product.

[0003] However, the cooling range of the existing cooling devices for processing polyurethane foam plastics is small, resulting in low cooling efficiency and affecting their working quality. Therefore, we propose a cooling device for processing polyurethane foam plastics to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a device for processing foam plastics.

[0005] The technical problems of the present invention are mainly solved by the following technical solutions:

[0006] A device for processing foam plastics includes a cooling box with a switch door arranged on its side wall:

[0007] An aggregate tray is suspended and fixed in the cooling box through a support. A serpentine medium cooling pipe is arranged at the bottom of the aggregate tray, and an air outlet is arranged on the side wall of the cooling box below the aggregate tray. A box body communicated with the cooling box is also arranged on the top of the cooling box. An air inlet is arranged on the top wall of the box body. A fan is suspended at the top inside the box body, and a diversion mechanism is arranged at the opening at the bottom of the box body below the fan. The diversion mechanism includes a rectangular frame. A U-shaped rod driven by an electric push rod I is arranged on the top of both sides of the rectangular frame. A plurality of groups of diversion plates are vertically arranged in the rectangular frame. A rotating shaft movably connected to the side wall of the rectangular frame is longitudinally arranged in the middle of the diversion plate. Vertical rods are arranged on both sides of the top of the diversion plate. A plurality of groups of vertical rods are connected to a cross bar above the rectangular frame, and electric push rods II are arranged at both ends of the cross bar and installed on the corresponding U-shaped rods.

[0008] Preferably, filter nets are arranged on both the air inlet and the air outlet.

[0009] Preferably, metal counterweights are evenly arranged at the bottom ends of the diversion plates.

[0010] Preferably, the side wall and the bottom wall of the aggregate tray are both of a mesh structure.

[0011] Preferably, the rotating shaft is fixedly connected to the diversion plate, and both ends of the rotating shaft are fixed on the corresponding inner walls of the rectangular frame through bearings.

[0012] Preferably, the length of the box body is less than that of the cooling box, and the width of the box body is equal to that of the cooling box.

[0013] Preferably, convex seats are provided at the tops of both ends of the cross bar, and the output shaft of the electric push rod II is connected to the corresponding convex seat.

[0014] The beneficial effects of the present invention are as follows: When the present invention is used, the coolant flowing in the medium cooling pipe can cool down the bottom of the aggregate tray and the bottom end surface of the product inside it. At the same time, the fan works to generate negative pressure to introduce the outside cold air flow into the box body through the air inlet, and then flows into the cooling box and contacts the product on the aggregate tray to cool it down, and then is discharged from the air outlet. At the same time, the coverage range of the air flow introduced by the fan is expanded by changing the orientation of the deflector, so that the air blowing cooling work on the products in different areas of the aggregate tray is fully carried out.

Detailed Embodiments

[0018] The technical solutions of the present invention will be further specifically described below through embodiments and in combination with the drawings.

[0019] An equipment for processing foam plastics includes a cooling box 1 with a switch door on its side wall:

[0020] An aggregate tray 3 is suspended and fixed in the cooling box 1 through a support 2. A serpentine medium cooling pipe 4 is arranged at the bottom of the aggregate tray 3, and an air outlet 5 is arranged on the side wall of the cooling box 1 below the aggregate tray 3. The top of the cooling box 1 is also provided with a box body 6 communicated with it. An air inlet 7 is arranged on the top wall of the box body 6, and a fan 8 is also suspended at the top inside the box body 6;

[0021] At the bottom opening of the box body 6 below the fan 8, a diversion mechanism 9 is provided. The diversion mechanism 9 includes a rectangular frame 91. On the top of both sides of the rectangular frame 91, a U-shaped rod 93 driven by an electric push rod I 92 is erected. Inside the rectangular frame 91, multiple groups of diversion plates 94 are vertically arranged. Among them, a rotating shaft 95 that is longitudinally arranged in the middle of the diversion plate 94 and is movably connected to the side wall of the rectangular frame 91 is provided. On both sides of the top of the diversion plate 94, vertical rods 96 are provided. Among them, multiple groups of vertical rods 96 are connected to a cross bar 97 located above the rectangular frame 91, and electric push rods II 98 installed on the corresponding U-shaped rods 93 are provided at both ends of the cross bar 97.

[0022] In this embodiment, filter nets 10 are provided on both the air inlet 7 and the air outlet 5. Through the filter nets 10, foreign objects from the outside are prevented from entering the box body 6 and the cooling box 1.

[0023] In this embodiment, metal counterweights 11 are evenly arranged at the bottom end of the diversion plates 94.

[0024] In this embodiment, the side wall and the bottom wall of the aggregate tray 3 are both of a mesh structure. With this design, it is convenient for air to flow through the side wall apertures.

[0025] In this embodiment, the rotating shaft 95 and the diversion plate 94 are fixedly connected, and both ends of the rotating shaft 95 are fixed on the corresponding inner walls of the rectangular frame 91 through bearings.

[0026] In this embodiment, the length of the box body is less than the length of the cooling box, and the width of the box body is equal to the width of the cooling box.

[0027] As Figure 1 、 2 shown, convex seats 12 are provided at the top of both ends of the cross bar 97, and the output shaft of the electric push rod II 98 is connected to the corresponding convex seat 12.

[0028] As Figure 1 shown, when in use, the coolant flowing in the medium cooling pipe 4 can cool down the bottom of the aggregate tray 3 and the bottom end face of the product inside it. At the same time, the fan 8 works to generate negative pressure to introduce the outside cold air flow through the air inlet 7 into the box body 6, then flow into the cooling box 1 and contact the product on the aggregate tray 3 to cool it down, and then be discharged from the air outlet 5;

[0029] When in use, the electric push rod I92 can drive the C-shaped rod 93 to drive components such as the rectangular frame 91 to move up and down, thereby adjusting the height of the diversion mechanism 9 to meet the production requirements. At the same time, the output shafts of a group of electric push rods II98 extend, and the output shafts of the other electric push rods II98 contract, thereby driving the cross bar 97 to perform a horizontal displacement. During the displacement process, the cross bar 97 drives the corresponding vertical rod 96 to squeeze the top of the diversion plate 94 to rotate around the rotating shaft 95, so that the diversion plate 94 is in an inclined state. At this time, the airflow introduced by the fan 8 can be blown to the edges on both sides of the cooling box 1 through the air duct formed between the inclined diversion plates 94, thereby playing a role in wind cooling the products at the edges of the aggregate tray 3, realizing expanding the coverage range of the airflow introduced by the fan 8 by changing the orientation of the diversion plate 94, so that it fully performs wind cooling work on the products in different areas in the aggregate tray 3, and realizing cooling and temperature reduction of the products in different areas in the cooling box 1 without increasing the number of fans 8;

[0030] When only the products directly below the fan 8 need to be cooled, the electric push rod II98 drives the cross bar 97 to drive the vertical rod 96 to move, so that the vertical rod 96 does not contact the top of the diversion plate 94. At this time, under the gravitational pull of the counterweight 11, the diversion plate 94 will be in a vertical state, and the airflow blowing from top to bottom can smoothly blow onto the products directly below the fan 8. At this time, even if the diversion plate 94 makes a slight swing under the influence of the wind, it will not affect the above effect.

[0031] The above has described the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as used to limit the scope of implementation of the present invention. All equal changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
