Description

Technical Field

[0001] The invention belongs to the field of building material production equipment, and in particular relates to a multifunctional lightweight composite thermal insulation wallboard forming device and a forming method thereof. Background Art

[0002] As the construction industry's requirements for energy conservation and environmental protection continue to increase, multifunctional lightweight composite insulation wall panels are increasingly used in the construction field due to their many advantages such as light weight, insulation, and sound insulation. Their molding process relies on special molding devices. For example, Announcement No.: CN2598732Y discloses a multifunctional lightweight composite insulation wall panel molding machine. The performance of the device directly affects the quality and production efficiency of the wall panels.

[0003] During the vibration forming process of the multifunctional lightweight composite thermal insulation wallboard, after the raw materials are injected into the mold, the vibration operation interacts with the flow characteristics of the raw materials themselves. The vibration force generated during the vibration causes the raw materials to move in the mold. When the raw materials flow to the four corners of the mold, due to the sudden change in flow direction, eddy currents and accumulation are easily formed. This situation makes the extrusion pressure on the four corners of the mold much higher than other parts. Continuous high-frequency vibration will cause the four corners of the mold to bear high extrusion pressure and friction for a long time. As time goes by, the wear rate of the four corners of the mold accelerates sharply, which not only reduces the dimensional accuracy of the mold and affects its precise control of the wallboard forming size, but also may cause deformation, cracks and other problems in the mold, shorten the service life of the mold, and increase production costs. In addition, excessive extrusion friction at the four corners of the mold will cause excessive extrusion of the wallboard material near the area, which may cause defects in the internal structure of the wallboard, such as uneven internal pore distribution, too large pores in some places, and too dense in others, which will affect the overall thermal insulation performance, mechanical strength and other key indicators of the wallboard, reduce product quality, and increase the defective rate.

[0004] To this end, a multifunctional lightweight composite thermal insulation wall panel forming device and a forming method thereof are proposed. Summary of the invention

[0010] Preferably, the corner pressure length indicating mechanism includes a first sleeve fixedly arranged on the top of the storage box, a length indicating rod is vertically slidably provided on the top of the first sleeve, the lower end of the length indicating rod extends to the interior of the first sleeve and is fixedly provided with a permanent magnet block, an electromagnetic block is fixedly provided on the bottom inner wall of the first sleeve, the electromagnetic block and the permanent magnet block are arranged correspondingly in position, a second spring is provided on the rod wall of the length indicating rod, and both ends of the second spring are respectively fixedly connected to the permanent magnet block and the first sleeve.

[0011] Preferably, the corner extrusion wear metering mechanism includes a second sleeve fixedly arranged on the side wall of the first sleeve, a sliding rod is vertically fixedly arranged inside the second sleeve, a sliding block is arranged on the rod wall of the sliding rod, a third spring is sleeved on the rod wall of the sliding rod, and both ends of the third spring are respectively fixedly connected to the sliding block and the second sleeve, a touch switch is fixedly arranged on one side of the bottom of the sliding block, a pulse counter is fixedly arranged on the inner wall of the second sleeve, an insulating touch head is fixedly arranged on one side of the permanent magnet block, and one end of the insulating touch head extends to the interior of the second sleeve and is arranged corresponding to the position of the touch switch.

[0012] Preferably, the bottom plate is a U-shaped plate, wherein both ends of the inner side surfaces of the two side plates are fixedly provided with limit stop bars, and the number of the screw locking assemblies is four, and they are symmetrically distributed in pairs.

[0013] A method for using a multifunctional lightweight composite thermal insulation wallboard forming device, the method comprising the following steps: S1: First, complete the installation of the mold, install the four side panels on the upper surface of the bottom plate through the screw locking assembly, and the four side panels are arranged in a rectangular distribution. After the installation is completed, clean the inner surfaces of the bottom plate and the side panels and apply a release agent; S2: Inject raw materials into the mold and start vibrating. During the vibration process, the wear-resistant pressure sensor can detect the size of the extrusion pressure of the raw materials on the corner of the mold in real time. As the vibrator gradually approaches the position of the wear-resistant pressure sensor, the extrusion pressure of the raw materials on the wear-resistant pressure sensor will gradually increase, and the pressure value detected by the wear-resistant pressure sensor will gradually increase. The PLC controller will immediately increase the power supply of the electromagnetic block at the corresponding position through the control circuit, so that the electromagnetic repulsion force generated by the electromagnetic block itself pushes the permanent magnet block upward, and the length indicator rod can be gradually extended from the inside of the first sleeve. The staff can judge the size of the extrusion pressure at this corner by observing the extended length of the length indicator rod, so as to gradually reduce the power of the vibrator; S3: When the extrusion pressure of the raw material on the corner of the mold reaches a large value in a short time and exceeds the set threshold, the PLC controller will immediately start the liquid pump. The liquid pump can pump the release agent or water-based lubricant from the storage box into the liquid supply pipe and the L-shaped spray hollow plate, and then evenly spray it on the corners of the two side plates through the spray holes; S4: When the extrusion pressure of the raw material on the corner of the mold reaches the threshold in a short time, the PLC controller will control the current to the electromagnetic block to be the largest through the control circuit, so that the permanent magnet block drives the length indicator rod to move upward by the maximum distance. During the movement, the permanent magnet block will drive the insulating contact head to move together until the insulating contact head contacts the touch switch. When the touch switch is triggered, a pulse signal will be generated and sent to the pulse counter. When the pulse counter receives the pulse signal, a counting action will be generated, which can complete the counting of the extrusion wear at the four corners of the mold; S5: After the full vibration is completed, the surface needs to be smoothed and calendered with a spatula or other tools, and finally, it is left to stand for curing and demoulding.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The pressure detection mechanism, corner pressure indicator mechanism and PLC controller work together to monitor the extrusion pressure at the four corners of the mold in real time. When the vibrator is close to the corner of the side plate, the wear-resistant pressure sensor detects the change in extrusion pressure and feeds it back to the PLC controller. The PLC controller controls the electromagnetic block to change the electromagnetic repulsion force, so that the extended length of the indicator rod can directly reflect the size of the extrusion pressure, which is convenient for the staff to reduce the power of the vibrator in time, effectively reduce the wear of the extrusion force on the four corners of the mold, extend the service life of the mold, ensure the mold accuracy, reduce production costs, and improve production quality.

[0015] 2. Through the set lubrication spray mechanism, when the extrusion pressure reaches the set threshold, the lubrication spray mechanism will be automatically started, and the PLC controller controls the liquid pump to spray the release agent or water-based lubricant on the corners of the mold. This targeted lubrication operation not only lubricates when the extrusion pressure may cause greater friction, avoiding the waste of lubricant, but also forms a lubricating layer between the material and the mold corner, greatly reducing friction, and can also play a cooling role, preventing the heat generated by friction from affecting the mold and material performance, thereby improving product quality.

[0016] 3. The corner extrusion wear metering mechanism can accurately measure the number of extrusions at the four corners of the mold. When the extrusion force reaches the threshold, the permanent magnet drives the insulating touch head to trigger the touch switch. The pulse counter counts and feeds back to the PLC controller. The count increases on the display. When the count reaches the set value, the PLC controller alarms to remind you to replace the mold, ensuring that the mold is replaced in time before wear affects product quality, thereby ensuring the production quality of the wallboard and reducing the production of defective products.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] like Figure 1-Figure 7 As shown, a multifunctional lightweight composite thermal insulation wall panel forming device comprises a bottom plate 1 and four side plates 2 arranged on the upper surface of the bottom plate 1, and the four side plates 2 are spliced ​​in a rectangular shape, and screw locking assemblies 3 are arranged between two adjacent side plates 2 and between the side plates 2 and the bottom plate 1. The bottom plate 1 adopts a U-shaped plate, wherein both ends of the inner side surfaces of the two side plates 2 are fixedly provided with limit stop bars 9, the number of the screw locking assemblies 3 is four, and they are symmetrically distributed in pairs, and the two sides of the bottom plate 1 can clamp two of the side plates 2, and then lock them through the screw locking assemblies 3, and at the same time, the other two side plates 2 are inserted and locked through the screw locking assemblies 3, and also include: Four pressure detection mechanisms 4 are respectively arranged at a corner of the inner side surface of the four side panels 2, and are used to monitor the pressure size at the corner of the four side panels 2. The pressure detection mechanism 4 includes a wear-resistant pressure sensor 41. A mounting groove 42 is opened at a corner of the inner side surface of the side panel 2. A mounting plate 43 is slidably arranged inside the mounting groove 42. The wear-resistant pressure sensor 41 is fixedly embedded on the outer side surface of the mounting plate 43. Two elastic telescopic rods 44 are symmetrically fixed between the mounting plate 43 and the mounting groove 42. The raw material inside the mold will cause compression to the wear-resistant pressure sensor 41 and the mounting plate 43. At this time, the wear-resistant pressure sensor 41 can detect the size of the extrusion force in real time. At the same time, the mounting plate 43 will also move toward the inside of the mounting groove 42 and compress the elastic telescopic rod 44, which will play a role in the wear-resistant pressure sensor 41. It has a buffering protection function to avoid damage to the wear-resistant pressure sensor 41 caused by excessive extrusion; the elastic telescopic rod 44 includes a sleeve 441 fixedly arranged on the inner wall of the installation groove 42, and a connecting rod 442 is slidably arranged inside the sleeve 441. A first spring 443 is fixedly arranged between one end of the connecting rod 442 and the inner wall of the sleeve 441, and two limit blocks 444 are symmetrically fixedly arranged at one end of the connecting rod 442. The inner wall of the sleeve 441 is provided with a limit groove matched with the limit block 444. When the connecting rod 442 is compressed, the first spring 443 is squeezed. When the connecting rod 442 is not squeezed, the elastic force of the first spring 443 resets the connecting rod 442, and the limit block 444 can limit the distance that the connecting rod 442 moves inside the sleeve 441.

[0021] Four lubricating spray mechanisms 5 are respectively arranged at the four corners of the side wall of the bottom plate 1 and the top corners of the four side plates 2, and are used to lubricate the corners of the four side plates 2. The lubricating spray mechanism 5 includes a storage box 51 fixedly arranged on the side wall of the bottom plate 1, a liquid pump 52 is fixedly arranged inside the storage box 51, and a liquid supply pipe 53 extending outward is fixedly arranged at the output end of the liquid pump 52. An L-shaped spray hollow plate 54 is fixedly arranged on the top of the side plate 2, and a plurality of evenly distributed spray holes 55 are opened on the side of the L-shaped spray hollow plate 54. One end of the liquid supply pipe 53 away from the storage box 51 is fixedly connected to the L-shaped spray hollow plate 54. When the liquid pump 52 works, the release agent or water-based lubricant in the storage box 51 can be pumped into the liquid supply pipe 53 and the L-shaped spray hollow plate 54, and then evenly sprayed on the corners of the two side plates 2 through the spray holes 55. The release agent or water-based lubricant can form a lubricating layer between the material and the mold corner to reduce friction.

[0022] The corner pressure length indicating mechanism 6 is fixedly arranged on the top of the sliding spray mechanism and is used to display the pressure size at the four corners. The corner pressure length indicating mechanism 6 includes a first sleeve 61 fixedly arranged on the top of the storage box 51. The top of the first sleeve 61 is vertically slidably provided with a length indicating rod 62. The lower end of the length indicating rod 62 extends to the inside of the first sleeve 61 and is fixedly provided with a permanent magnet block 63. The bottom inner wall of the first sleeve 61 is fixedly provided with an electromagnetic block 64. The electromagnetic block 64 is arranged correspondingly to the position of the permanent magnet block 63. The rod wall of the length indicating rod 62 is provided with a second spring 65, and the first sleeve 61 is provided with a second spring 65. The two ends of the second spring 65 are fixedly connected to the permanent magnet block 63 and the first sleeve 61 respectively. After the electromagnetic block 64 is powered on, the electromagnetic repulsion force generated by the electromagnetic block 64 itself gradually increases, so that the permanent magnet block 63 is pushed upward under the action of the electromagnetic repulsion force, so that the length indicator rod 62 can gradually extend from the inside of the first sleeve 61. As the vibrator is closer to the wear-resistant pressure sensor 41, the longer the length indicator rod 62 extends, and the staff can judge the size of the extrusion pressure at this corner by observing the extended length of the length indicator rod 62.

[0023] The corner extrusion wear metering mechanism 7 is fixedly arranged on the top of the sliding spray mechanism, and is used to measure the number of extrusions of the four corners and judge the wear degree of the four corners. The corner extrusion wear metering mechanism 7 includes a second sleeve 71 fixedly arranged on the side wall of the first sleeve 61, a sliding rod 72 is vertically fixed inside the second sleeve 71, a sliding block 73 is arranged on the rod wall of the sliding rod 72, a third spring 74 is sleeved on the rod wall of the sliding rod 72, and the two ends of the third spring 74 are respectively fixedly connected to the sliding block 73 and the second sleeve 71, a touch switch 75 is fixedly arranged on one side of the bottom of the sliding block 73, a pulse counter 76 is fixedly arranged on the inner wall of the second sleeve 71, and a pulse counter 76 is fixedly arranged on the inner wall of the permanent magnet block 63. An insulating touch head 77 is fixedly provided on one side, and one end of the insulating touch head 77 extends to the inside of the second sleeve 71 and is arranged corresponding to the position of the touch switch 75. When the insulating touch head 77 contacts the touch switch 75, the touch switch 75 will generate a pulse signal when it is triggered and send it to the pulse counter 76. The pulse counter 76 will generate a counting action when receiving the pulse signal. The moment the insulating touch head 77 contacts the touch switch 75, the slider 73 moves on the slide rod 72 and compresses the third spring 74, which can provide a buffering displacement for the touch switch 75 and avoid extrusion damage to the touch switch 75.

[0024] The PLC controller 8 is fixedly arranged on the side wall of the base plate 1 , and the pressure detection mechanism 4 , the lubrication spray mechanism 5 , the corner pressure length indicating mechanism 6 and the corner extrusion wear measuring mechanism 7 are all electrically connected to the PLC controller 8 .

[0025] The operating principle of the present invention is described as follows: the staff needs to first strictly inspect the bottom plate 1 and the four side plates 2, carefully check whether there are cracks, deformation, wear or corrosion on the appearance, and then assemble the base and the four side plates 2. During the assembly process, the four side plates 2 are spliced ​​into a rectangle and placed on the upper surface of the bottom plate 1, and then the side plates 2 and the side plates 2 are fixed to the bottom plate 1 by the screw locking assembly 3. After the installation is completed, the inner surfaces of the bottom plate 1 and the side plates 2 are cleaned and a release agent is applied; Then, the staff injects the mixture of raw materials such as sand, gravel, cement, etc. into the mold and vibrates it through an inserted vibrator. The insertion depth of the vibrator should reach 5-10 cm of the unvibrated raw materials in the lower layer to promote the full fusion of the upper and lower layers. When vibrating, the vibrating rod needs to be kept stable to avoid touching the mold wall and the internal embedded parts. When the vibrator moves to the corner where the two adjacent side panels 2 are connected, the vibrator will accelerate the fluidity of the raw materials, thereby increasing the squeezing force of the raw materials on the wear-resistant pressure sensor 41 (the wear-resistant pressure sensor 41 itself is made of wear-resistant material and has good wear resistance. It can withstand the friction and impact of the raw materials during the vibration process, reduce the wear caused by long-term contact with the raw materials, extend the service life of the sensor, and ensure its stability and reliability. Working close to the ground), at this time, the wear-resistant pressure sensor 41 can detect the size of the extrusion force in real time. At the same time, the mounting plate 43 will also be squeezed and moved to the inside of the mounting groove 42 and compress the elastic telescopic rod 44 (the mounting plate 43 and the mounting groove 42 are processed by high-precision processing technology, so the sealing is high, and the raw materials will not enter, and the density of the wallboard will not be affected). As the vibrator gradually approaches the position of the wear-resistant pressure sensor 41, the extrusion force of the raw materials on the wear-resistant pressure sensor 41 will gradually increase. At this time, the pressure value detected by the wear-resistant pressure sensor 41 gradually increases, and the wear-resistant pressure sensor 41 will feedback an electrical signal to the PLC controller 8 (the wear-resistant pressure sensor 41 adopts a strain gauge sensor. When the wear-resistant pressure sensor 4 When subjected to the extrusion force, the elastic sensitive element inside is deformed, causing the strain gauge pasted on its surface to be deformed as well. The resistance value of the strain gauge will change accordingly. The change of the resistance value is converted into a voltage or current signal through the measuring circuit. The signal is amplified and filtered before being sent to the PLC controller 8. After receiving the signal feedback, the PLC controller 8 immediately increases the power supply of the electromagnetic block 64 at the corresponding position through the control circuit, so that the electromagnetic repulsion force generated by the electromagnetic block 64 itself gradually increases, so that the permanent magnet block 63 is pushed upward under the action of the electromagnetic repulsion force, so that the length indicator rod 62 can gradually extend from the inside of the first sleeve 61, and as the vibrator is farther away from the wear-resistant pressure sensor 41, the length indicator rod 62 can gradually extend from the inside of the first sleeve 61. The closer the length of the indicator rod 62 is, the greater the extension length of the indicator rod 62 is. The staff can judge the size of the extrusion pressure at this corner by observing the extension length of the indicator rod 62, so as to gradually reduce the power of the vibrator and reduce the degree of wear of the extrusion pressure on the four corners of the mold. At the same time, the extrusion friction on the wallboard material is reduced, and the molding quality of the wallboard is improved (because the indicator rod 62 is set at the four corners of the mold, the staff can directly observe the length of the indicator rod 62 when inserting the vibrator at the four corners of the mold. This can roughly judge the length of the indicator rod 62 and roughly control the power of the vibrator. Because the extrusion pressure value at the four corners of the mold in this process does not exceed the threshold value and is within the tolerable range, it is allowed to adjust the power of the vibrator in an imprecise manner); When the extrusion pressure of the raw material on the corner of the mold reaches a large value (due to the viscosity and high water content of the raw material and the fact that the four right angles of the mold are prone to eddy current dead corners, the extrusion pressure is large), and the pressure value of the wear-resistant pressure sensor 41 reaches the threshold value set inside the PLC controller 8 (5000Pa), the PLC controller 8 will immediately start the liquid pump 52 to work. The liquid pump 52 can pump the release agent or water-based lubricant from the storage box 51 into the liquid supply pipe 53 and the L-shaped spray hollow plate 54, and then spray it evenly on the corners of the two side plates 2 through the spray hole 55 (the spray hole 55 is located at a higher position and will not be splashed and blocked by raw materials), so that the release agent or water-based lubricant fits the inner side of the corner of the mold and flows downward. The release agent or water-based lubricant can flow between the material and the mold corner. A lubricating layer is formed between the corners to reduce friction. At the same time, it can also play a certain cooling role to prevent excessive heat generated by friction from affecting the performance of the mold and materials, thereby improving the molding quality of the wallboard. In this process, the lubricant is sprayed only when the extrusion pressure reaches a level that may cause greater friction, thus achieving targeted lubrication operations and avoiding unnecessary waste of lubricants. It can also more effectively solve the friction problem caused by the large extrusion pressure at the four corners of the mold (in order to prevent the lubricant from being quickly washed away, a release agent or water-based lubricant with higher viscosity and adhesion is used to make it better adhere to the mold surface and resist the scouring of raw materials under high-frequency vibration. For example, a water-based lubricant containing a special thickener can form a thicker and tougher lubricating film at the corners of the mold that is not easily washed away); When the extrusion pressure of the raw material on the corner of the mold reaches the threshold value (5000Pa), the PLC controller 8 will control the current to the electromagnetic block 64 to be maximum through the control circuit, so that the permanent magnet block 63 drives the length indicator rod 62 to move upward to the maximum distance. During the movement, the permanent magnet block 63 will drive the insulating touch head 77 to move together until the insulating touch head 77 contacts the touch switch 75. When the touch switch 75 is triggered, a pulse signal will be generated and sent to the pulse counter 76. When the pulse counter 76 receives the pulse signal, a counting action will be generated (the touch switch 75 adopts a mechanical contact, and the internal mechanical structure changes the circuit state by external force, and a current or voltage mutation is generated at the moment of circuit on and off to form a pulse). The pulse counter 76 then feeds back an electrical signal to the PLC controller 8, so that the PLC controller 8 displays a The count increases, so that the extrusion wear at the four corners of the mold can be counted (because the vibrator needs to be frequently moved inside the mold, in the process of forming a wall panel, the vibrator may be inserted into the four corners of the mold multiple times. Therefore, the degree of extrusion wear of the four corners of the mold is different, so the wear of the four corners needs to be calculated). When the extrusion wear count reaches a certain value (for example, 100 times), the PLC controller 8 will start the built-in alarm module and remind the staff to disassemble and replace the mold to ensure the production quality of subsequent wall panels (this counting process will only be triggered when the extrusion pressure of the raw material on the corner of the mold reaches the threshold, that is, the pressure value is 5000Pa. If it is lower than 5000Pa, it will not be triggered. Even if the extrusion pressure value fluctuates frequently, it will not have any impact on the counting action); When the staff fully vibrates the raw materials inside the mold, they observe the surface of the raw material mixture. When the surface no longer sinks significantly, no bubbles emerge, and cement slurry appears, it indicates that the vibration of that part is completed. Then slowly pull out the vibration until the vibration is completed. After the end, the surface of the material in the mold may be uneven, with bubbles, roughness and other problems. It is necessary to use tools such as spatula to smooth and calender the surface to make it smooth and flat to meet the design appearance requirements. Finally, static maintenance and demolding are carried out to complete the molding of the multifunctional lightweight composite insulation wall panels.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.

8. A method for using the multifunctional lightweight composite thermal insulation wallboard forming device as claimed in claim 6, characterized in that: The method of use includes the following steps: S1: first, complete the installation of the mold, install the four side panels (2) on the upper surface of the bottom plate (1) through the screw locking assembly (3), and the four side panels (2) are arranged in a rectangular distribution. After the installation is completed, clean the inner surfaces of the bottom plate (1) 1 and the side panels (2) 2 and apply a release agent; S2: Injecting raw materials into the mold and starting to vibrate. During the vibration process, the wear-resistant pressure sensor (41) can detect the size of the extrusion pressure of the raw materials on the mold corner in real time. As the vibrator gradually approaches the position of the wear-resistant pressure sensor (41), the extrusion pressure of the raw materials on the wear-resistant pressure sensor (41) gradually increases, and the pressure value detected by the wear-resistant pressure sensor (41) gradually increases. The PLC controller (8) will immediately increase the power supply of the electromagnetic block (64) at the corresponding position through the control circuit, so that the electromagnetic repulsion force generated by the electromagnetic block (64) itself pushes the permanent magnet block (63) upward, and the length indicator rod (62) can be gradually extended from the inside of the first sleeve (61). The staff can judge the size of the extrusion pressure at this corner by observing the extended length of the length indicator rod (62), thereby gradually reducing the power of the vibrator; S3: When the extrusion pressure of the raw material on the corner of the mold reaches a large value in a short time and exceeds the set threshold value, the PLC controller (8) will immediately start the liquid pump (52) to work. The liquid pump (52) can pump the release agent or water-based lubricant from the storage box (51) into the liquid supply pipe (53) and the L-shaped spray hollow plate (54), and then evenly spray it on the corners of the two side plates (2) through the spray hole (55); S4: When the extrusion pressure of the raw material on the corner of the mold reaches a threshold value in a short time, the PLC controller (8) controls the current flowing to the electromagnetic block (64) to be maximum through the control circuit, so that the permanent magnet block (63) drives the length indicator rod (62) to move upward by the maximum distance. During the movement, the permanent magnet block (63) drives the insulating contact head (77) to move together until the insulating contact head (77) contacts the touch switch (75). When the touch switch (75) is triggered, a pulse signal is generated and sent to the pulse counter (76). When the pulse counter (76) receives the pulse signal, a counting action is generated, so that the extrusion wear at the four corners of the mold can be counted; S5: After the full vibration is completed, the surface needs to be smoothed and calendered with a spatula or other tools, and finally, it is left to stand for curing and demoulding.
