When the pressing operation is completed, the hydraulic cylinder drives the mounting frame and the two extrusion shafts to move upward. At this time, the trapezoidal extrusion blocks on both sides squeeze the two extrusion shafts, so that the two L-shaped lifting plates move toward each other synchronously, and then the pressed foam is lifted at the first time so that it moves upward synchronously with the mounting frame and leaves the top of the workbench.

[0014] 2. In the utility model, when the mounting frame is moving upward, the sliding assembly drives the U-shaped push plate to reciprocate horizontally one back and forth, so that the waste can be quickly discharged through the waste outlet hole, and through the setting of two sprockets and chains, the two reciprocating screws can be driven to rotate synchronously, avoiding the U-shaped waste push plate from getting stuck during the horizontal movement.

[0022] 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.

[0023] Example: Reference Figure 1-5The waste discharge device for foam processing shown in the figure comprises a workbench 1, and a U-shaped top plate 2 is commonly provided on both sides of the workbench 1, a hydraulic cylinder 3 is provided on the top of the U-shaped top plate 2, the output end of the hydraulic cylinder 3 passes through the U-shaped top plate 2 and is fixedly provided with a mounting frame 4, a pressing plate 5 is provided on the top inner wall of the mounting frame 4, circular holes are provided on the opposite inner walls of the mounting frame 4, extrusion shafts 6 are slidably installed in the two circular holes, one end of the two extrusion shafts 6 extends into the mounting frame 4 and is fixedly provided with an L-shaped lifting plate 7, and elastic components are provided on the sides of the two L-shaped lifting plates 7, trapezoidal extrusion blocks 9 are provided on both sides of the U-shaped top plate 2, and the two trapezoidal extrusion blocks 9 are respectively adapted to the two extrusion shafts 6, a transmission cavity is provided in the U-shaped top plate 2, and two sliding holes are provided on the bottom inner wall of the transmission cavity, rectangular sliders 16 are slidably installed in the two sliding holes through sliding components, and a U-shaped waste pushing plate 17 is commonly fixedly installed at the bottom of the two rectangular sliders 16.

[0024] With the above structure, when in use, first place the foam on the top of the workbench 1, and then drive the installation frame 4 and the pressing plate 5 downward to press the material through the hydraulic cylinder 3. After the pressing operation is completed, the hydraulic cylinder 3 drives the installation frame 4 and the two extrusion shafts 6 to move upward. At this time, the trapezoidal extrusion blocks 9 on both sides squeeze the two extrusion shafts 6, so that the two L-shaped lifting plates 7 move synchronously towards each other, and then lift the pressed foam at the first time so that it moves upward synchronously with the installation frame 4 and leaves the top of the workbench 1. When the installation frame 4 moves upward to a suitable position, the two trapezoidal extrusion blocks 9 slowly release the extrusion shaft 6, so that the two L-shaped lifting plates 7 move synchronously in the opposite direction, so that the pressed foam falls back to the top of the workbench 1. When the installation frame 4 moves upward, it drives the U-shaped push plate 17 to move back and forth horizontally under the action of the sliding component, discharges the waste material and resets it.

[0025] like Figure 2 As shown, the elastic component includes a compression spring 8, one end of the compression spring 8 is fixedly installed on the side of the L-shaped lifting plate 7, and the other end of the compression spring 8 is fixedly installed on the side inner wall of the mounting frame 4. The advantage of this arrangement is that, through the arrangement of the compression spring 8, when the extrusion effect on the extrusion shaft 6 is released, the elastic action of the compression spring 8 can drive the L-shaped lifting plate 7 to achieve a reset function.

[0026] Specifically, when the mounting frame 4 drives the extrusion shaft 6 to move downward to the inclined surface of the trapezoidal extrusion block 9, the extrusion effect of the trapezoidal extrusion block 9 on the extrusion shaft 6 gradually disappears, thereby driving the L-shaped lifting plate 7 to reset synchronously through the elastic effect of the compression spring 8.

[0027] like Figure 2As shown, the top of the workbench 1 is provided with an avoidance groove compatible with the mounting frame 4, and the side inner walls of the avoidance grooves close to each other are provided with sliding grooves compatible with the two L-shaped lifting plates 7. The advantage of this arrangement is that through the arrangement of the avoidance grooves and the sliding grooves, the L-shaped lifting plates 7 can be moved to the bottom of the foam during the pressing process, and the lifting function of the foam can be realized when the mounting frame 4 moves upward.

[0028] Specifically, since the foam material is very soft, when the pressing plate 5 is pressing the material, the mounting frame 4 and the L-shaped lifting plate 7 will not interfere with the pressing process and will enter the avoidance groove and the sliding groove. When the pressing operation is completed, the mounting frame 4 moves upward, and through the extrusion action of the extrusion shaft 6 and the trapezoidal extrusion block 9, the two L-shaped lifting plates 7 are driven to move toward each other, thereby lifting the pressed foam.

[0029] like Figure 4 As shown, the sliding assembly includes two reciprocating screw rods 10, the two ends of the two reciprocating screw rods 10 are respectively rotatably installed on the relative inner walls of the transmission chamber, the two reciprocating screw rods 10 are connected by a transmission unit, and two rectangular sliders 16 are respectively threadedly installed on the two reciprocating screw rods 10. The advantage of such an arrangement is that through the arrangement of the two reciprocating screw rods 10, the function of driving the two rectangular sliders 16 to move synchronously can be realized.

[0030] Specifically, when the two reciprocating screws 10 rotate, they can drive the two rectangular sliders 16 to move horizontally synchronously, and then drive the U-shaped waste pushing plate 17 to push the foam waste on the top of the workbench 1 to discharge the waste.

[0031] like Figure 5 As shown, the transmission unit includes two sprockets 11, which are respectively fixedly sleeved on two reciprocating screw rods 10, and chains 12 are installed on the two sprockets 11 in meshing relationship with each other. A discharge motor 14 is fixedly installed on the side of the U-shaped top plate 2, and the output shaft of the discharge motor 14 is connected to the end of one of the reciprocating screw rods 10. The advantage of such an arrangement is that the two reciprocating screw rods 10 can be driven to rotate synchronously through the arrangement of the two sprockets 11 and the chain 12.

[0032] Specifically, starting the discharge motor 14 drives one of the reciprocating screws 10 and one of the sprockets 11 to rotate synchronously, and then drives the other sprocket 11 and the reciprocating screw 10 to rotate synchronously through the meshing action of the sprocket 11 and the chain 12, thereby avoiding the U-shaped waste push plate 17 from getting stuck during the horizontal movement.

[0033] like Figure 1 As shown, the inner wall of the side of the U-shaped top plate 2 is provided with a waste outlet hole 18 which is compatible with the U-shaped waste pushing plate 17. The advantage of such a setting is that the waste outlet hole 18 can be quickly discharged through the waste outlet hole 18.

[0034] Specifically, when the U-shaped waste pushing plate 17 moves horizontally, it can drive the waste on the top of the workbench 1 to be quickly discharged from the waste outlet 18 .

[0035] like Figure 1 As shown, a plurality of support columns are arranged at the bottom of the workbench 1, and anti-skid pads are arranged at the bottoms of the plurality of support columns. The advantage of such arrangement is that the stability of the device when placed can be improved through the arrangement of the anti-skid pads.

[0036] Specifically, by arranging support columns and anti-slip pads at the bottom of the workbench 1, the stability of the device when placed can be effectively improved.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
