Description

TECHNICAL FIELD

[0001] The application belongs to the field of building material production equipment, and particularly relates to a multifunctional light composite thermal insulation wallboard forming device and a forming method thereof. BACKGROUND

[0002] With the continuous improvement of the requirements of the building industry on energy saving and environmental protection, the multifunctional light composite thermal insulation wallboard is increasingly widely applied in the building field due to its advantages such as light weight, thermal insulation, sound insulation and the like, and its forming process depends on a special forming device. For example, the multifunctional light composite thermal insulation wallboard forming machine disclosed in the announcement No. CN2598732Y directly influences the quality and production efficiency of the wallboard.

[0003] In the vibration forming process of the multifunctional light composite thermal insulation wallboard, after the raw materials are injected into the mold, the vibration operation and the flow characteristics of the raw materials interact with each other, the vibration force generated during the vibration operation promotes the movement of the raw materials in the mold, and when the raw materials flow to the four corner regions of the mold, the vortex and accumulation phenomenon is easily formed due to the sudden change of the flow direction. This situation makes the extrusion pressure borne by the four corner regions of the mold much higher than that borne by other regions. The continuous high-frequency vibration makes the four corner regions of the mold long-term bear high extrusion pressure and frictional action. With the lapse of time, the wear speed of the four corner regions of the mold is rapidly accelerated. This not only reduces the dimensional accuracy of the mold and influences the accurate control of the forming size of the wallboard, but also may cause the mold to appear deformation, cracks and the like, shortens the service life of the mold and increases the production cost. In addition, the excessive extrusion of the wallboard material close to the four corner regions of the mold due to the excessive extrusion and friction of the four corner regions of the mold may cause the internal structure of the wallboard to have defects, for example, the internal pore distribution is uneven, the pore is too large in some places and is too dense in some places, thereby influencing the key indexes such as the thermal insulation performance and the mechanical strength of the wallboard as a whole, reducing the product quality and increasing the rate of defective products.

[0039] Four lubrication spray mechanisms 5 are arranged at the corners of the side walls of the bottom plate 1 and the top corners of the four side plates 2 respectively, for lubricating the corners of the four side plates 2. The lubrication spray mechanism 5 comprises a storage box 51 fixedly arranged on the side wall of the bottom plate 1, an internal liquid pump 52 fixedly arranged in the storage box 51, an outwardly extending liquid supply pipe 53 fixedly arranged at the output end of the internal liquid pump 52, an L-shaped spray hollow plate 54 fixedly arranged at the top of the side plate 2, a plurality of evenly distributed spray holes 55 arranged on the side surface of the L-shaped spray hollow plate 54, and the L-shaped spray hollow plate 54 fixedly connected with the end of the liquid supply pipe 53 away from the storage box 51. When the internal liquid pump 52 works, the release agent or water-based lubricant in the storage box 51 is pumped into the internal 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 corners of the mold, reducing friction.

[0040] The corner pressure display mechanism 6 is fixedly arranged at the top of the sliding spray mechanism, for displaying the pressure of the four corners. The corner pressure display mechanism 6 comprises a first sleeve 61 fixedly arranged at the top of the storage box 51, a length display rod 62 vertically slidingly arranged at the top of the first sleeve 61, a permanent magnet block 63 fixedly arranged at the lower end of the length display rod 62 and extending into the internal of the first sleeve 61, a power-on magnet block 64 fixedly arranged on the inner wall of the bottom of the first sleeve 61 and corresponding to the permanent magnet block 63, a second spring 65 sleeved on the rod wall of the length display rod 62 and fixedly connected with the permanent magnet block 63 and the first sleeve 61 at both ends, and the power-on magnet block 64 generates an electromagnetic repulsion force after being connected to the power supply, which gradually increases, so that the permanent magnet block 63 is pushed upward under the action of the electromagnetic repulsion force, thereby enabling the length display rod 62 to gradually extend out of the internal of the first sleeve 61. The closer the vibrator is to the wear-resistant pressure sensor 41, the greater the extension length of the length display rod 62. The work personnel can judge the size of the extrusion pressure at the corner by observing the extension length of the length display rod 62.

[0041] The corner extrusion abrasion degree metering mechanism 7 is fixedly arranged at the top of the sliding and spraying mechanism, is used for metering the extrusion times of the four corners, judging the abrasion degree of the four corners, and comprises a second sleeve 71 fixedly arranged on the side wall of the first sleeve 61, a sliding rod 72 vertically fixed in the second sleeve 71, a sliding block 73 arranged on the rod wall of the sliding rod 72, a third spring 74 sleeved on the rod wall of the sliding rod 72 and fixedly connected with the sliding block 73 and the second sleeve 71 at both ends, a touch switch 75 fixedly arranged on one side of the bottom of the sliding block 73, a pulse counter 76 fixedly arranged on the inner wall of the second sleeve 71, an insulating touch head 77 fixedly arranged on one side of the permanent magnet block 63 and extended to the inside of the second sleeve 71 and arranged in position corresponding to the touch switch 75, and when the insulating touch head 77 is in contact with the touch switch 75, the touch switch 75 generates a pulse signal when triggered and sends it to the pulse counter 76, and the pulse counter 76 generates a counting action when receiving the pulse signal. At the moment when the insulating touch head 77 is in contact with the touch switch 75, the sliding block 73 moves on the sliding rod 72 and compresses the third spring 74, which can provide a buffer displacement function for the touch switch 75 and avoid the phenomenon of extrusion damage to the touch switch 75.

[0042] The PLC controller 8 is fixedly arranged on the side wall of the bottom plate 1, and the pressure detection mechanism 4, the lubricating spraying mechanism 5, the corner pressure lengthening mechanism 6 and the corner extrusion abrasion degree metering mechanism 7 are electrically connected with the PLC controller 8.

[0043] The operation principle of the present application is described as follows: The staff needs to strictly check the bottom plate 1 and the four side plates 2, carefully check whether there is crack, deformation, abrasion or corrosion on the appearance, then assemble the base and the four side plates 2, splice the four side plates 2 into a rectangle and place them on the upper surface of the bottom plate 1 during the assembly process, and then fix the side plates 2 and the bottom plate 1 through the screw locking assembly 3. After the installation is completed, clean the inner surfaces of the bottom plate 1 and the side plates 2 and apply release agent;

[0044] Then, the staff will sand cement mixture of raw materials into the inside of the mold and by plug-in vibrator, the depth of the vibrator inserted to reach the lower layer of 5-10 cm of the unmixed raw materials, to facilitate the upper and lower layers of fully integrated, vibration, need to keep the stability of the vibrator stick, avoid touching the mold wall and the internal embedded parts, when the vibrator moves to the adjacent two side plate 2 connected corner, because the vibrator will accelerate the mobility of raw materials, so that the raw materials on the wear-resistant pressure sensor 41 extrusion force increases (wear-resistant pressure sensor 41 itself is made of wear-resistant material, with good wear resistance, can withstand the friction and impact of raw materials in the process of vibration, reduce the wear caused by long-term contact with raw materials, prolong the service life of the sensor, to ensure its stable and reliable work), at this time, the wear-resistant pressure sensor 41 can detect the size of the extrusion force, at the same time, the installation plate 43 will also be extruded to move to the inside of the installation slot 42 and compress the elastic expansion rod 44 (the installation plate 43 and the installation slot 42 are processed by high-precision process, 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 close to 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, the wear-resistant pressure sensor 41 will feed back an electrical signal to the PLC controller 8 (wear-resistant pressure sensor 41 uses strain gauge sensor, when the wear-resistant pressure sensor 41 is extruded, the internal elastic sensitive element is deformed, causing the strain gauge pasted on its surface to also deform, the resistance value of the strain gauge will change, the change of resistance value is converted into voltage or current signal through the measurement circuit, the signal is sent to the PLC controller 8 after amplification and filtering), the PLC controller 8 receives the signal feedback immediately, gradually increases the power of the corresponding position of the energized magnetic block 64 through the control circuit, so that the electromagnetic repulsion of the energized magnetic block 64 itself gradually increases, so that the permanent magnet block 63 is pushed out upward under the action of the electromagnetic repulsion, so as to make the length indicator rod 62 gradually extend out of the inside of the first sleeve 61, and the closer the vibrator is to the wear-resistant pressure sensor 41, the longer the length indicator rod 62 extends, the staff can judge the size of the extrusion force at this corner by observing the length of the length indicator rod 62, so as to gradually reduce the power of the vibrator, reduce the wear degree of the extrusion force on the four corners of the mold, at the same time, reduce the extrusion friction of the wallboard material, improve the forming quality of the wallboard (since the length indicator rod 62 is arranged at the four corners of the mold, the staff can directly observe the length of the length indicator rod 62 when holding the vibrator at the four corners of the mold, which can roughly judge the length of the length indicator rod 62 and roughly control the power of the vibrator, since the extrusion force value of the four corners of the mold in this process does not exceed the threshold value, within the bearing range, so it allows non-precise adjustment of the power of the vibrator);

[0045] When the extrusion force of the raw material on the corner of the mold reaches a large value (the extrusion force is large due to the characteristics of the viscosity and high water content of the raw material and the characteristics of the straight corners of the mold that are prone to vortex dead angles), and the pressure value of the wear-resistant pressure sensor 41 reaches the threshold value set in the PLC controller 8 (5000 Pa), the PLC controller 8 will immediately start the liquid pump 52 to work. The liquid pump 52 can store the release agent or water-based lubricant inside the tank 51 into the inside of the liquid supply pipe 53 and the L-shaped spraying hollow plate 54, and then uniformly sprayed through the spraying holes 55 at the corners of the two side plates 2 (the position of the spraying holes 55 is higher, and the raw material will not splash and block), so that the release agent or water-based lubricant adheres to the inside of the corner of the mold and flows downward, and the release agent or water-based lubricant can form a lubricating layer between the material and the corner of the mold, reducing friction, and also having a certain cooling effect, preventing the heat generated by friction from being too high to affect the performance of the mold and the material, and improving the forming quality of the wallboard. This process only sprays lubricant when the extrusion force reaches a level that may cause significant friction, achieving targeted lubrication operation, avoiding unnecessary lubricant waste, and more effectively solving the friction problem at the corners of the mold caused by large extrusion force (in order to avoid the possibility of the lubricant being quickly washed away, a release agent or water-based lubricant with high viscosity and adhesion is used, which can better adhere to the surface of the mold and resist the washing of the raw material under high-frequency vibration, for example, a water-based lubricant containing a special thickening agent can form a thick and tough lubricating film at the corners of the mold, which is not easily washed away);

[0046] When the extrusion force of the raw material on the corner of the mold reaches the threshold value (5000Pa), the PLC controller 8 controls the maximum current to the energized electromagnetic block 64 through the control circuit, so that the permanent magnet block 63 drives the length rod 62 to move upward with the maximum distance, and the permanent magnet block 63 moves together with the insulating touch head 77 in the moving process, until the insulating touch head 77 contacts the touch switch 75, the touch switch 75 generates a pulse signal when triggered and sends it to the pulse counter 76, the pulse counter 76 generates a counting action when receiving the pulse signal (the contact of the touch switch 75 adopts a mechanical type, which changes the circuit state by external force, and generates a current or voltage mutation to form a pulse in the circuit on-off moment), and the pulse counter 76 feeds back an electric signal to the PLC controller 8, so that the PLC controller 8 displays a count increase on the display, so as to complete the counting of the extrusion wear of the four corners of the mold (since the vibrator needs to move frequently in the inside of the mold, the vibrator may be inserted into the four corners of the mold several times in the process of forming a wallboard, therefore, the wear degree of the four corners of the mold is different, so it is necessary to calculate the wear degree of the four corners), when the count of the extrusion wear reaches a certain value (for example, 100 times), the PLC controller 8 starts the built-in alarm module and reminds the worker to disassemble and replace the mold, to ensure the production quality of the subsequent wallboard (this counting process will only be triggered when the extrusion force of the raw material on the corner of the mold reaches the threshold value, i.e. the pressure value is 5000Pa, if it is lower than 5000Pa, it will not be triggered, even if the extrusion force value exists frequent fluctuation, but it will not cause any influence on the counting action);

[0047] When the workers fully vibrate the raw materials in the mold, observe the surface of the raw material mixture, when the surface no longer significantly subsides, no bubbles come out and the cement paste is out, it indicates that the site is vibrated, then slowly pull out the vibrator until the vibration is completed, after the end, the surface of the material in the mold may be uneven, there are bubbles, pockmarks and other problems, the surface needs to be smoothed and polished with a spatula and other tools, so that the surface is smooth and flat, meets the design appearance requirements, finally, static curing and demolding are carried out, and the multifunctional lightweight composite thermal insulation wallboard forming is completed.

[0048] The above only describes the preferred embodiments of the present application, and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.

5. A method for using the multifunctional lightweight composite thermal insulation wallboard forming device according to claim 2, characterized in that: The method 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 surface of the bottom plate (1) and the side panels (2) and apply a release agent; S2: Inject the raw material into the mold and start vibrating. During the vibrating process, the wear-resistant pressure sensor (41) can detect the size of the extrusion pressure of the raw material 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 material 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 and exceeds the set threshold in a short time, 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 inside the storage box (51) into the liquid supply pipe (53) and the inside of 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 force 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 to the electromagnetic block (64) to be the 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) 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, 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 tools, and finally, it is left to stand for curing and demoulding.
