[0002] Polystyrene foam is referred to as EPS. It is a light polymer. It is made by adding a foaming agent to polystyrene resin and heating it to soften it, generating gas to form a rigid closed-cell foam plastic.

[0003] Manufacturers usually use plastic foam to package and protect valuable and fragile products. However, after the foam is discarded after one use, it will have an impact on the environment, and thus needs to be recycled. At present, the foam is generally recycled by hot melting through a foam clumping machine. Before the foam is hot melted, the user is generally required to cut the foam into small pieces and then put it into the foam clumping machine. When the foam melts in the collection box, the user is required to pour water on the collection box to facilitate the removal of the foam blocks, which makes the recycling speed slow.

DETAILED DESCRIPTION

[0026] Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] A hot melting block device for recycling EPS plastic foam, such as Figure 1-3 As shown, it includes a support plate 1, a foaming clumping machine 2, a moving mechanism 4 and a discharging mechanism 5. The foaming clumping machine 2 is provided on the right side of the top of the support plate 1, the moving mechanism 4 is provided on the top of the support plate 1, and the discharging mechanism 5 is provided on the moving mechanism 4.

[0029] The moving mechanism 4 includes a first bracket 41, a slide rail frame 42 and a slider 43. The first bracket 41 is symmetrically arranged in the middle of the top of the support plate 1. The first bracket 41 is provided with a slide rail frame 42. The slider 43 is slidably arranged in the slide rail frame 42.

[0030] The discharging mechanism 5 includes a sliding frame 51, a first fixed rod 52, a first movable plate 53, a first spring 54 and a first fixed plate 55. The sliding frame 51 is connected between the sliders 43. The first fixed rod 52 is symmetrically arranged on the right side of the sliding frame 51. The first movable plate 53 is slidably connected between the first fixed rods 52. The first movable plate 53 is in sliding contact with the sliding frame 51. The first spring 54 is connected between the first movable plate 53 and the first fixed rod 52. The first fixed plate 55 is symmetrically arranged on the right side of the top of the support plate 1.

[0031] When the user needs to recycle the foam, the present device can be used. First, the recycled foam is placed in the foam clumping machine 2, the foam clumping machine 2 is started, and the foam clumping machine 2 is used to melt the foam. The melted foam will fall into the sliding frame 51. Then the user can move the sliding frame 51 and the slider 43 to the left along the slide rail frame 42. The sliding frame 51 drives the first movable plate 53 and the first fixed rod 52 to move to the left. When the first movable plate 53 moves to the left until it contacts the first fixed plate 55, the first fixed plate 55 resists the first movable plate 53, so that the first spring 54 is compressed. At this time, the sliding frame 51 continues to move to the left. Since the first movable plate 53 no longer blocks the position directly below the sliding frame 51, the melted foam blocks in the sliding frame 51 fall downward. Then the user moves the sliding frame 51 and the first movable plate 53 to the right to reset, and the first spring 54 is reset. When the foam does not need to be melted and recycled, the foam clumping machine 2 is closed.

The first gear 66 engages with the second gear 67 to make the first rotating shaft 62 on the front side rotate in the opposite direction. In this way, the crushing rods 63 on both sides rotate in the opposite direction, so that the foam can be crushed, which is convenient for the foam clumping machine 2 to melt the foam. After the crushing is completed, the motor 65 is turned off.

[0035] The feeding mechanism 7 also includes a third bracket 71, a second rotating shaft 72, a bevel gear 73, a second fixed plate 74, a third rotating shaft 75, a first supporting frame 76, a fourth rotating shaft 77, a pulley 78, a guide wheel 79, a flat belt 710, a third gear 711 and a rack 712. The third bracket 71 is provided on the right side of the housing 61, and the second rotating shaft 72 is rotatably provided on the third bracket 71. The second rotating shaft 72 and the first rotating shaft 62 on the front side are both provided with a bevel gear 73, and the two bevel gears 73 are meshed.

[0036] The first rotating shaft 62 on the front side rotates and meshes with two bevel gears 73, so that the second rotating shaft 72 rotates, and the fourth rotating shaft 77 and the third gear 711 are driven to rotate through the pulley 78 and the flat belt 710, and the third gear 711 meshes with the rack 712, so that the sliding frame 51 automatically moves to the left side, and there is no need to manually move the sliding frame 51 out. After the foam in the sliding frame 51 is taken out, the motor 65 can be rotated in the opposite direction, so that the first rotating shaft 62, the second rotating shaft 72, the fourth rotating shaft 77 and the third gear 711 on the front side all rotate in the opposite direction, and the third gear 711 meshes with the rack 712, so that the rack 712 and the sliding frame 51 move to the right and reset.

[0037] It also includes a manual flushing mechanism 8, which includes a second support frame 81, a water tank 82, a nozzle 83, a cover plate 84, a second fixed rod 85 and a second movable plate 86. The foaming machine 2 is provided with a second support frame 81 on both the front and rear sides, the water tank 82 is connected between the second support frames 81 by bolts, the nozzle 83 is connected to the bottom of the water tank 82, the cover plate 84 is movably provided on the top of the water tank 82, the second fixed rod 85 is symmetrically provided on the left side of the top of the support plate 1, and a second movable plate is slidably provided between the second fixed rods 85, and the second movable plate 86 is slidably connected to the nozzle 83.

[0038] The user can remove the cover 84 and then fill the water tank 82 with water. After the water filling is completed, put the cover 84 back in place. Then, when the sliding frame 51 is filled with melted foam, the user can move the second movable plate 86 to the left. At this time, the second movable plate 86 no longer blocks the nozzle 83, so that the water in the water tank 82 is sprayed into the sliding frame 51 through the nozzle 83, so that the foam solidifies into blocks, which makes it convenient for the user to take out the foam blocks. The water tank 82 is used for a long time, and scale will be generated inside. The user can remove the water tank 82 for cleaning.

[0039] It also includes an automatic flushing mechanism 9, which includes a second spring 91, a third fixed plate 92, a second fixed frame 93, a third spring 94 and a movable block 95.

The second fixed frame 93 is slidably provided with a movable block 95 on the top, and the third spring 94 is connected between the movable block 95 and the second fixed frame 93.

[0040] When the sliding frame 51 drives the second fixed frame 93 and the movable block 95 to move to the right, the movable block 95 contacts the third fixed plate 92, the movable block 95 is pressed inward, and the third spring 94 is compressed. When the movable block 95 moves to a point where it is no longer in contact with the third fixed plate 92, the third spring 94 drives the movable block 95 to move upward and reset. When the sliding frame 51 drives the second fixed frame 93 and the movable block 95 to move out to the left, the movable block 95 drives the third fixed plate 92 and the second movable plate 86 to move to the left, and the second spring 91 is compressed. In this way, there is no need to manually move the second movable plate 86. When the second movable plate 86 cannot continue to move to the left, the movable block 95 disengages from the third fixed plate 92. Under the reset action of the second spring 91, the second movable plate 86 moves to the right and resets.

[0041] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
