Description

Technical Field

[0001] The present invention belongs to the technical field of rock plate conveying and compounding, and in particular relates to a high-bearing capacity and pressure-resistant honeycomb core composite rock plate compounding machine. Background Art

[0002] At present, high-bearing capacity and compressive honeycomb core composite rock slabs have been widely used in the market because of their high strength of rock slabs and light weight and high compressive resistance of honeycomb cores. In the production process of composite rock slabs, rock slabs and honeycombs need to be delivered to the designated position of the compounding machine by means of a conveyor to carry out the compounding process. For example, Announcement No.: CN217946712U discloses a rock slab compounding machine.

[0003] At present, when common composite machines press composite rock panels, heating devices are generally used inside the mold to assist in the curing of glue to enhance the bonding strength between the rock panel and the honeycomb core. However, during the long-term use of the composite machine mold, due to mold wear, corrosion and other reasons, its thermal conductivity decreases, resulting in uneven heating of different parts of the composite rock panel, which will not only affect the curing effect of the glue, resulting in incomplete curing of the glue in some areas, thereby reducing the overall bonding strength of the composite rock panel, but may also cause deformation of the rock panel and other problems, seriously affecting product quality and yield rate; in addition, due to mold wear, corrosion and other reasons, the composite rock panel may be partially not firmly adhered or not adhered at all, which greatly affects the high bearing capacity and compressive resistance of the composite rock panel, and cannot meet the market demand for high-quality products.

[0004] To this end, a high-bearing capacity and compressive-resistant honeycomb core composite rock plate composite machine is proposed. Summary of the invention

[0021] The lower heating mechanism 8 is arranged inside the lower mold 4 and is used to heat the lower surface of the lower rock plate. The lower heating mechanism 8 includes a plurality of lower semiconductor temperature control plates 81. The lower mold 4 adopts a hollow structure. A plurality of evenly distributed heat insulation sleeves 82 are fixed inside the lower mold 4. The plurality of lower semiconductor temperature control plates 81 are respectively fixed inside the heat insulation sleeves 82. The heat insulation sleeves 82 can avoid temperature interference between adjacent lower semiconductor temperature control plates 81.

[0023] The automatic material picking mechanism 10 is arranged between the two sides of the upper mold 3 and the two sides of the lower mold 4. The automatic material picking mechanism 10 includes material picking plates 101 elastically arranged on the two sides of the lower mold 4. The upper surfaces of the two material picking plates 101 are fixedly provided with pulling plates 102. The upper ends of the two pulling plates 102 are provided with pulling holes 103. Electromagnetic telescopic rods 104 are arranged on both sides of the upper mold 3. One end of the two electromagnetic telescopic rods 104 can be inserted into the two pulling holes 103 respectively. The pulling holes 103 make the strip holes able to provide a certain amount of downward movement for one end of the electromagnetic telescopic rod 104. During the cooperation process between the upper mold 3 and the lower mold 4, one end of the electromagnetic telescopic rod 104 is inserted into the pulling hole 103, so that the upper mold 3 and the lower mold 4 are connected; connecting plates 105 are fixedly provided on both sides of the material picking plate 101, and a first spring 106 is fixedly provided between the upper surfaces of the two connecting plates 105 and the inner wall of the lower mold 4.

When the touch head 107 on the connecting plate 105 contacts the touch switch 108, the touch switch 108 is triggered; the electromagnetic telescopic rod 104 includes a shell 12 fixedly provided on the side wall of the upper mold 3, a moving rod 13 is laterally inserted on one side of the shell 12, one end of the moving rod 13 extends to the interior of the shell 12 and is fixedly provided with a permanent magnet block 14, an electromagnetic block 15 is fixedly provided on the inner wall of the shell 12 and at a position corresponding to the position of the permanent magnet block 14, a second spring 16 is fixedly provided between the permanent magnet block 14 and the electromagnetic block 15, and a power supply of the electromagnetic block 15 is provided. After the electromagnetic block 15 is energized, a strong magnetic attraction is generated to attract the permanent magnet block 14 and the moving rod 13 connected thereto, so that one end of the moving rod 13 is completely moved out of the pulling hole 103.

[0024] The PLC controller 11 is fixedly arranged on the top of the base 1 , and the first cylinder 6 , the conveyor 5 , the upper heating mechanism 7 , the lower heating mechanism 8 , the local pressing mechanism 9 and the automatic material taking mechanism 10 are all electrically connected to the PLC controller 11 .

[0025] The operating principle of the present invention is described as follows: the staff conveys the upper rock plate, the lower rock plate and the honeycomb core to one side of the lower mold 4 through the conveyor 5, and then the staff takes the upper rock plate, the lower rock plate and the honeycomb core from the conveyor 5, first puts the lower rock plate into the lower mold 4 and applies a layer of glue on the upper surface, then puts the honeycomb core on the upper surface of the lower rock plate and applies a layer of glue on the upper surface, and finally puts the upper rock plate on the upper surface of the honeycomb core, and the preparation work is completed; The staff manually controls the PLC controller 11 to start the first cylinder 6, the upper semiconductor temperature control board 71 and the lower semiconductor temperature control board 81. The first cylinder 6 extends to drive the upper mold 3 to move slowly downward until the upper mold 3 accurately reaches the inside of the lower mold 4, and the upper rock plate, the honeycomb core and the lower rock plate are tightly pressed together (the pressing time is usually about 15 minutes). The upper semiconductor temperature control board 71 and the lower semiconductor temperature control board 81 are respectively installed inside the upper mold 3 and the lower mold 4, one end of which is the heating end and the other end is the cooling end. When the two are powered on, the heating end quickly heats up and the cooling end cools down accordingly. In this process, the heat generated by the heating end is mainly used to heat the inside of the upper mold 3 and the lower mold 4 respectively, and the heat is transmitted through the upper mold 3 and the lower mold 4. 4. Conducted to the surface of the upper and lower rock plates, and then the upper rock plate, honeycomb core and lower rock plate are heated in all directions (the heating temperature is controlled between 200-232°C). On the one hand, heating can effectively improve the performance of glue, reduce the viscosity of glue, and significantly enhance its fluidity, so as to evenly cover the surface of the rock plate and honeycomb core, fully fill the microscopic gaps, greatly increase the contact area between glue and material, and significantly improve the bonding force. On the other hand, heating makes the surface molecules of the rock plate and honeycomb core material more active, and the surface activity is greatly improved, which is conducive to the formation of more stable chemical bonds or physical adsorption between the glue molecules and the surface molecules of the material, and comprehensively enhances the bonding effect, ensuring that the quality and performance of the composite rock plate reach the optimal state; During the heating and pressing process, multiple temperature sensors 93 arranged on the lower surface of the upper mold 3 and multiple pressure and temperature compatible sensors 83 arranged inside the lower mold 4 can monitor the temperature of the upper rock plate surface and the lower pressure plate surface in real time in the region. During the long-term use of the mold, if the thermal conductivity of the upper mold 3 and the lower mold 4 changes in certain areas due to excessive wear of the material, then the local surface of the upper rock plate and the lower rock plate will experience temperature fluctuations. At this time, the temperature values ​​detected by the temperature sensors 93 and the pressure and temperature compatible sensors 83 in the temperature abnormality area will be significantly different from those in other normal positions. Temperature value, once such a situation occurs, the temperature sensor 93 and the pressure and temperature compatible sensor 83 will quickly feedback electrical signals to the PLC controller 11. After receiving the electrical signal feedback, the PLC controller 11 immediately plays a regulating role and accurately adjusts the power of the upper semiconductor temperature control board 71 and the lower semiconductor temperature control board 81 in the area. Through this intelligent adjustment method, it can ensure that the surface temperature of the upper rock plate and the surface temperature of the lower rock plate are always maintained within a constant ideal range, thereby greatly improving the composite quality of the upper rock plate, honeycomb core and lower rock plate, and ensuring the stability and reliability of the performance of the composite rock plate product; During the pressing process of the upper mold 3 and the lower mold 4, the pressure and temperature compatibility sensor 83 inside the lower mold 4 can also detect the external force applied by the lower rock plate. Since the pressure and temperature compatibility sensor 83 is evenly distributed in the lower mold 4, it can detect the pressure values ​​of multiple areas on the lower surface of the lower rock plate. If the upper mold 3 and the lower mold 4 are excessively worn, the pressure borne by the pressure and temperature compatibility sensor 83 below the worn position will be abnormal, significantly lower than the pressure value at the normal position (under normal circumstances, the appropriate pressure range for the upper mold 3 and the lower mold 4 is between 0.5-1.0MPa). Once such pressure abnormality occurs, the pressure and temperature compatibility sensor 83 will immediately feedback an electrical signal to the PLC controller 11. After receiving the signal, the PLC controller 11 responds quickly and immediately starts the second cylinder 92 just above the abnormal position. The second cylinder 92 starts working, and its piston rod extends to drive the pressing plate 91 from the upper The mold 3 is smoothly moved out from the inside and acts precisely on the surface of the upper rock plate. Through this additional pressing action, the upper rock plate, honeycomb core and lower rock plate at the abnormal pressure position are subjected to pressing again. During the continuous pressure adjustment process, the system always closely monitors the value change of the pressure and temperature compatible sensor 83 until the pressure value detected by the sensor at the abnormal position returns to the normal range and is consistent with the pressure value at other normal positions (stable between 0.5-1.0MPa), thereby effectively avoiding the problem of partial loose adhesion or complete non-adhesion of the upper rock plate, honeycomb core and lower rock plate due to uneven pressure, and greatly ensuring the quality of the composite product (due to the large number of pressing plates 91 and the small size of pressing plates 91, the normal area will not be over-pressed due to the excessive size of pressing plates 91. If the area of ​​one pressing plate 91 cannot cover the abnormal position during the additional pressing process, more than two pressing plates 91 will be started for pressing); After the pressing process is completed, the PLC controller 11 immediately changes the current direction of the upper semiconductor temperature control plate 71 and the lower semiconductor temperature control plate 81 by means of the control circuit. At this time, the part originally used as the heating end is quickly switched to the cooling mode, and the cooling end is switched to the heating mode, thereby realizing the cooling operation inside the upper mold 3 and the lower mold 4, and can quickly reduce the temperature of the upper mold 3 and the lower mold 4 to the suitable range of 20℃-25℃. The cold amount is efficiently transmitted to the surface of the upper rock plate and the lower rock plate through the upper mold 3 and the lower mold 4, thereby cooling the upper rock plate, the honeycomb core and the lower rock plate that have been pressed. The whole cooling process lasts about 1 hour. Compared with the natural cooling method (cooling time is 4-8 hours), this technical solution does not need to wait for a long time for the upper mold 3 and the lower mold 4 to naturally drop from the high temperature state to room temperature, which significantly shortens the production cycle, greatly improves the production efficiency, and helps to achieve efficient and continuous industrial production; During the cooperation between the upper mold 3 and the lower mold 4, the moving rods 13 on both sides of the upper mold 3 will move synchronously with the downward movement of the upper mold 3. When the moving rods 13 move downward and contact the upper ends of the pulling rods on both sides of the lower mold 4, since the upper ends of the pulling rods are provided with guide surfaces, the moving rods 13 are squeezed by the guide surfaces at the moment when they continue to move downward and contact the guide surfaces, and are forced to retract into the shell 12. During this process, the moving rods 13 drive the permanent magnet block 14 connected thereto to overcome the elastic force of the second spring 16 and move toward the direction of the electromagnetic block 15 until the upper mold 3 moves downward to the lowest position, and when the end of the moving rod 13 is accurately aligned with the pulling hole 103 on the pulling rod, the elastic force of the second spring 16 pushes the permanent magnet block 14. One end of the moving rod 13 is smoothly inserted into the pulling hole 103. At this time, the upper mold 3 and the lower mold 4 are connected through the moving rod 13 and the pulling rod. When the cooling process is completed, the staff controls the first cylinder 6 to perform the retraction action by operating the PLC controller 11, thereby driving the upper mold 3 to move upward. In this process, the moving rods 13 on both sides of the upper mold 3 will synchronously drive the pulling rod to rise together, and the pulling rod will further drive the material removal plate 101 to move upward. The material removal plate 101 firmly lifts the lower rock plate from both sides, thereby automatically lifting the pressed upper rock plate, honeycomb core and lower rock plate from the inside of the lower mold 4. The staff can directly take away the composite material that has been pressed, which is convenient to operate. When the feeding plate 101 moves upward, the connecting plates 105 on both sides thereof will be driven by the feeding plate 101, so that the connecting plates 105 overcome the elastic force of the first spring 106 and move outward. When the touch head 107 on the connecting plate 105 contacts the touch switch 108, the touch switch 108 is triggered, and an electrical signal is immediately fed back to the PLC controller 11. After receiving the feedback signal, the PLC controller 11 quickly connects the power supply of the electromagnetic block 15 through the control circuit. After the electromagnetic block 15 is energized, a strong magnetic attraction is generated to attract the permanent magnet block 14 and the moving rod 13 connected thereto, so that one end of the moving rod 13 is completely moved out of the pulling hole 103, so that the upper mold 3 can continue to move upward, and the feeding plate 101 quickly falls back and resets under the elastic force of the first spring 106, preparing for the next feeding, thereby ensuring the efficient and continuous operation of the entire feeding process.
