Description

Technical Field

[0001] This utility model relates to the field of pressing machine technology, specifically a pressing machine. Background Technology

[0002] The production process of polyurethane foam microwave absorbing material involves first cutting it into a four-sided pyramidal structure, then impregnating it with a microwave absorbing agent and a flame retardant, and finally drying it. The impregnation process is generally carried out using a roller press. For larger pyramids, due to the limitations of the rollers, manual impregnation is usually performed by foot or by using special equipment.

[0003] In existing corner cones, the weight gain process is generally controlled manually, which makes it difficult to guarantee the uniformity of the product.

[0004] To address the above problems, this utility model provides a material pressing machine. Utility Model Content

[0005] The purpose of this invention is to provide a pressing machine that, by matching the angle of the four-sided pyramidal groove in the extrusion plate with the angle of the product's pyramidal shape, controls the product's weight gain through compression height, thereby precisely controlling product consistency and solving the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a material pressing machine, including a material trough, an extrusion plate is provided at the upper end of the material trough, a hydraulic cylinder is provided at the upper end of the extrusion plate, and four-sided pyramidal grooves are symmetrically opened on both sides of the bottom end of the extrusion plate. A rectangular frame is provided inside the material trough, and a carrying plate is slidably arranged inside the rectangular frame. A lead screw is passed through the carrying plate, and a motor is provided at the end of the lead screw. A slot is symmetrically opened on the upper surface of the carrying plate. Several evenly distributed drainage holes are opened on the upper surface of the carrying plate and the bottom surface of the slot. The slot is used to place a pyramid, and the slot is adapted to the bottom of the pyramid.

[0007] Furthermore, columns are fixed at the four corners of the upper end of the material trough, and a top plate is fixed at the top of the columns. The hydraulic cylinder is fixedly installed in the middle of the upper end of the top plate, and the output end extends downward and is fixedly provided with a lifting plate. The four corners of the lifting plate are slidably connected to the outside of the columns. Connecting columns are fixed at the four corners of the upper end of the extrusion plate, and the upper end of the connecting column is fixed to the bottom end of the lifting plate.

[0008] Furthermore, rectangular grooves are symmetrically opened on both sides of the upper end of the material trough, and the bottom end of the rectangular frame is fixed on the bottom surface of the rectangular groove.

[0009] Furthermore, a guide rod is provided on the side of the lead screw. One end of the guide rod passes through the carrying plate and is fixed to the inner side wall of the rectangular frame. The other end of the guide rod is also fixed to the inner side wall of the rectangular frame. The motor is fixedly installed on the outer side wall of the end of the rectangular frame, and its output end extends and is fixedly connected to the end of the lead screw. The outer side of the lead screw away from the motor is rotatably connected to the inner side wall of the rectangular frame through a bearing. The lead screw is internally threaded to the carrying plate, and the guide rod is slidably connected to the inner side of the carrying plate.

[0010] Furthermore, support legs are fixed at the four corners of the bottom of the trough.

[0011] Furthermore, a drain pipe is fixedly connected to the middle of the bottom of the trough, and a solenoid valve is fixedly installed on the drain pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model provides a pressing machine that places the bottom ends of two pyramids into their corresponding slots. A motor then starts and drives a lead screw to rotate, causing a carrier plate to move horizontally in a straight line. When the carrier plate moves directly below the extrusion plate, the motor shuts off. A hydraulic cylinder then starts and drives the extrusion plate vertically downwards, causing the inner side of the pyramidal slots to adhere to and pass through the pyramids for extrusion. When the extrusion plate reaches its bottom, the hydraulic cylinder stops and drives the extrusion plate upwards to reset. During extrusion, the material seeping from the pyramids flows into the material trough through a drain hole. Finally, the lead screw reverses, driving the carrier plate outwards to remove the pyramids. The purpose of this design is to ensure that the angle of the pyramidal slots within the extrusion plate matches the angle of the product's pyramids, allowing for precise control of product weight gain and consistency through compression height.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] To address the technical challenge of effectively controlling product weight gain, such as... Figure 1-4 As shown, the following preferred technical solutions are provided:

[0021] A material pressing machine includes a material trough 1, an extrusion plate 8 is provided at the upper end of the material trough 1, a hydraulic cylinder 6 is provided at the upper end of the extrusion plate 8, and four-sided pyramidal grooves 9 are symmetrically opened on both sides of the bottom end of the extrusion plate 8. A rectangular frame 11 is provided inside the material trough 1, and a carrying plate 15 is slidably arranged inside the rectangular frame 11. A lead screw 12 is passed through the carrying plate 15, and a motor 14 is provided at the end of the lead screw 12. A slot 16 is symmetrically opened on the upper surface of the carrying plate 15. A plurality of evenly distributed drainage holes 17 are opened on the upper end of the carrying plate 15 and the bottom surface of the slot 16. The slot 16 is used to place a pyramid, and the slot 16 is adapted to the bottom of the pyramid.

[0022] Specifically, the bottom ends of the two pyramids are placed in their corresponding slots 16. Then, the motor 14 starts and drives the lead screw 12 to rotate, causing the carrier plate 15 to move horizontally in a straight line. When the carrier plate 15 moves directly below the extrusion plate 8, the motor 14 shuts off. Then, the hydraulic cylinder 6 starts and drives the extrusion plate 8 to move vertically downward, so that the inner side of the pyramidal groove 9 fits and passes through the pyramid for extrusion. When the extrusion plate 8 descends to the bottom, the hydraulic cylinder 6 stops and drives the extrusion plate 8 to return to its original position. During the extrusion process, the liquid seeping out of the pyramids flows into the material tank 1 through the drain hole 17. Finally, the lead screw 12 reverses and drives the carrier plate 15 to move outward, allowing the pyramids to be removed. The purpose of this design is to ensure that the angle of the pyramidal groove 9 in the extrusion plate 8 matches the angle of the product pyramids. By controlling the compression height, the weight gain of the product can be controlled, and the consistency of the product can be precisely controlled.

[0023] Furthermore, such as Figure 1-4 As shown, the following preferred technical solutions are provided:

[0024] A column 3 is fixedly installed at each of the four corners of the upper end of the material trough 1. A top plate 4 is fixedly installed at the top of the column 3. A hydraulic cylinder 6 is fixedly installed in the middle of the upper end of the top plate 4, and the output end extends downward and is fixedly installed with a lifting plate 5. The four corners of the lifting plate 5 are slidably connected to the outside of the column 3. A connecting column 7 is fixedly installed at each of the four corners of the upper end of the extrusion plate 8. The upper end of the connecting column 7 is fixedly installed on the bottom end of the lifting plate 5. The purpose of this design is to drive the lifting plate 5 to rise and fall vertically in a stable manner through the hydraulic cylinder 6, thereby driving the extrusion plate 8 to rise and fall vertically in a stable manner in a synchronous manner.

[0025] Furthermore, such as Figure 1 As shown, the following preferred technical solutions are provided:

[0026] Rectangular grooves 10 are symmetrically opened on both sides of the upper end of the material tank 1. The bottom end of the rectangular frame 11 is fixed on the bottom surface of the rectangular groove 10. The purpose of this design is to ensure that the extruded liquid enters the material tank 1.

[0027] Furthermore, such as Figure 1-3 As shown, the following preferred technical solutions are provided:

[0028] A guide rod 13 is provided on the side of the lead screw 12. One end of the guide rod 13 passes through the carrying plate 15 and is fixed to the inner wall of the rectangular frame 11. The other end of the guide rod 13 is also fixed to the inner wall of the rectangular frame 11. The motor 14 is fixedly installed on the outer wall of the end of the rectangular frame 11 and its output end extends and is fixedly connected to the end of the lead screw 12. The outer side of the lead screw 12 away from the motor 14 is rotatably connected to the inner wall of the rectangular frame 11 through a bearing. The lead screw 12 is internally threaded to the carrying plate 15, and the guide rod 13 is internally slidably connected to the carrying plate 15. The purpose of this design is to ensure that when the motor 14 drives the lead screw 12 to rotate, it drives the carrying plate 15 to move in a horizontal reciprocating linear motion.

[0029] Furthermore, such as Figure 1 As shown, the following preferred technical solutions are provided:

[0030] Support legs 2 are fixed at the four corners of the bottom of the material trough 1. The purpose of this design is to support the material trough 1 through the support legs 2.

[0031] Furthermore, such as Figure 1 As shown, the following preferred technical solutions are provided:

[0032] A drain pipe is fixedly connected to the middle of the bottom of the material trough 1, and a solenoid valve is fixedly installed on the drain pipe. The purpose of this design is to control the opening and closing of the drain pipe through the solenoid valve.

[0033] In summary: The bottom ends of the two pyramids are placed in their corresponding slots 16. Then, the motor 14 starts and drives the lead screw 12 to rotate, causing the carrier plate 15 to move horizontally in a straight line. When the carrier plate 15 moves directly below the extrusion plate 8, the motor 14 shuts off. Then, the hydraulic cylinder 6 starts and drives the extrusion plate 8 to move vertically downwards, causing the inner side of the pyramidal groove 9 to adhere to and pass through the pyramid for extrusion. When the extrusion plate 8 reaches its bottom, the hydraulic cylinder 6 stops and drives the extrusion plate 8 to return to its original position. During extrusion, the liquid seeping from the pyramids flows into the material trough 1 through the drain hole 17. Finally, the lead screw 12 reverses and drives the carrier plate 15 to move outwards, allowing the pyramids to be removed. The purpose of this design is to ensure that the angle of the pyramidal groove 9 within the extrusion plate 8 matches the angle of the product pyramids. By controlling the compression height, the weight gain of the product can be controlled, allowing for precise control of product consistency.
