Description

Technical Field

[0001] This invention relates to the field of energy-saving building material production equipment technology, specifically a rapid prototyping production equipment for prefabricated building exterior wall panels. Background Technology

[0002] Exterior wall insulation boards are an important and commonly used material in building envelopes. They offer excellent thermal insulation, effectively reducing heat loss and energy consumption during building use. As a typical energy-saving building material, they meet the requirements of modern architecture for energy conservation, environmental protection, and green development. Building exterior wall panel forming production equipment is a specialized mechanical device used for forming and processing exterior wall panels, capable of meeting the needs of mass production and standardization.

[0003] However, existing exterior wall panel forming equipment is easily affected by ambient temperature during pressing operations. Low temperatures result in lower adhesive curing and forming efficiency. Furthermore, most existing equipment stacks several semi-finished exterior wall panels vertically and then presses them down uniformly using a single pressing plate. However, due to differences in thickness, flatness, adhesive distribution, and decorative layer adhesion among the various semi-finished layers, the stress distribution during pressing is inconsistent, easily leading to excessive or insufficient pressure in certain areas. Excessive pressure can cause adhesive overflow and slippage or misalignment of the decorative surface; insufficient pressure can cause adhesive bubbling and loose adhesion, thus affecting the forming quality and product consistency of the exterior wall panels. Summary of the Invention

[0004] The purpose of this invention is to provide a rapid prototyping production equipment for prefabricated building exterior wall panels to solve the problem of uneven pressure on exterior wall panels in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rapid prototyping production equipment for prefabricated building exterior wall panels, comprising a pressure holding bracket and several pressure regulating forming units, several hydraulic devices are installed on the pressure holding bracket, a pressing component is installed on the output shaft of the hydraulic device, a pressure equalizing mechanism is symmetrically installed at the bottom end of the pressing component, and several lateral support components are installed at the bottom end of the pressure holding bracket. The pressure regulating molding unit includes a lower constant temperature support plate, a first elastic element, and an upper constant temperature pressure plate. Several lower constant temperature support plates are equidistantly installed on the lateral support members. Pressure regulating connectors are symmetrically installed at both ends of the upper constant temperature pressure plate. Pressure transmitting elements are installed on the pressure regulating connectors. The pressure transmitting elements are slidably connected to the pressure equalization mechanism. The pressure equalization mechanism is slidably connected to the lower constant temperature support plate. The top end of the first elastic element is connected to the pressure transmitting element, and the bottom end of the first elastic element is connected to the lower constant temperature support plate.

[0006] The molding production equipment is connected to an external control box, which contains a control system for operating the entire molding production equipment. The exterior wall panel consists of an insulation layer and a decorative surface. First, adhesive is applied to both sides of the insulation layer, and then the decorative surface is attached to the adhesive surface to form a semi-finished exterior wall panel to be molded.

[0007] The first elastic element is a first spring, which provides support for the upper thermostatic pressure plate when not in operation, keeping the upper thermostatic pressure plate separated from the lower thermostatic support plate. At the same time, it also provides a restoring force for the upper thermostatic pressure plate to return to its original position after operation.

[0008] During operation, the semi-finished exterior wall panels to be formed are placed layer by layer on the lower constant temperature support plate in each pressure regulating forming unit. Then, the control system activates the hydraulic device, and the output shaft of the hydraulic device drives the pressing component to descend, which in turn drives the pressure equalization mechanism on it to descend.

[0009] The pressure regulating connector includes a force transmission shell, a detection chamber inside the force transmission shell, the force transmission shell is installed at both ends of the upper constant temperature pressure plate, a force transmission slide plate is slidably installed inside the force transmission shell, a detection element is installed inside the force transmission slide plate, the bottom end of the detection element abuts against the bottom end of the detection chamber, and several pressure regulating elements are installed inside the force transmission slide plate, the bottom end of the pressure regulating elements abuts against the bottom end of the detection chamber.

[0010] The force transmission slide plate is equipped with an adjustment chamber, and connectors are installed at both ends of the adjustment chamber. The connectors are connected to a suction device through pipes. The force transmission slide plate is equipped with several sliding chambers, and the sliding chambers are connected to the adjustment chamber. The pressure regulating element includes a piston rod, which is slidably installed in a sliding cavity. A second elastic element is provided in the sliding cavity. The top end of the second elastic element is connected to the top end of the sliding cavity, and the bottom end of the second elastic element is connected to the top end of the piston rod. A push head is installed at the bottom end of the piston rod, and the push head abuts against the bottom end of the detection cavity.

[0011] The suction device is connected to the regulating chamber through a pipe. The suction device can inject air into the regulating chamber through the connector to pressurize the regulating chamber and the sliding chamber connected to it, thereby pushing the piston rod out of the sliding chamber; or it can extract the air from the regulating chamber to create negative pressure in the regulating chamber and the sliding chamber, causing the piston rod to retract into the sliding chamber.

[0012] The second elastic element is the second spring.

[0013] When the force-transmitting slide plate transmits pressure to the force-transmitting housing through the pressure regulating element, the slide plate first presses down on the second elastic element. The second elastic element, under pressure, pushes the piston rod downwards. The piston rod then applies downward pressure to the detection chamber of the force-transmitting housing through the pusher. Since the force-transmitting housing is connected to the upper thermostatic pressure plate, and the upper thermostatic pressure plate is supported upwards by the first elastic element, when the pusher presses down on the force-transmitting housing, the piston rod is subjected not only to the downward force from the slide plate and the second elastic element, but also to the upward reaction force transmitted by the first elastic element through the upper thermostatic pressure plate and the force-transmitting housing. Under the combined influence of these forces, the piston rod retracts relatively within the sliding chamber, and the second elastic element is also compressed accordingly. Because the pressure equalization mechanism maintains a pressing state under the action of the hydraulic device and does not produce further displacement, the corresponding pressure transmission component and force transmission slide plate also no longer produce displacement. As the pressure regulating element contracts, the force transmission shell slides upward along the force transmission slide plate. Furthermore, the greater the pressure applied by the hydraulic device, the greater the pressure applied by the force transmission slide plate to the pressure regulating element, the greater the compression of the second elastic element, and the corresponding increase in the upward displacement of the force transmission shell along the force transmission slide plate.

[0014] Furthermore, the detection element includes a detection slide rod and an induction coil. The detection slide rod is slidably installed inside the force transmission slide plate, and a detection spring is installed between the detection slide rod and the force transmission slide plate. The induction coil is installed inside the force transmission slide plate, and an iron core is provided inside the detection slide rod, with the iron core located inside the induction coil.

[0015] The detection spring is used to drive the detection slide rod, which is retracted into the force transmission slide plate, to spring back and reset.

[0016] The induction coil consists of a primary coil and a secondary coil. The induction coil and the iron core work together to form the LVDT sensor structure.

[0017] During the compression and contraction of the voltage regulating element, as the force transmission shell and the force transmission slide plate approach each other, the detection element is simultaneously compressed. The detection slide rod gradually retracts into the force transmission slide plate, causing the detection spring to compress. Simultaneously with the retraction of the detection slide rod, its internal iron core displaces relative to the induction coil and passes through the induction coil. According to the principle of LVDT sensors, when the iron core moves within the induction coil, the magnetic flux of the induction coil changes, outputting an electrical signal corresponding to the displacement of the iron core. The control system determines the displacement of the detection slide rod based on the strength of the electrical signal output by the induction coil. The greater the displacement, the greater the compression of the voltage regulating element, and the greater the pressure exerted on the corresponding voltage regulating element.

[0018] The control system synchronously collects and compares the electrical signals output by several groups of pressure regulating molding units. When the intensity of each group of electrical signals is within the error range of the set standard value, it indicates that the pressure applied by several groups of pressure regulating molding units to the corresponding exterior wall panels is basically the same, thereby achieving the effect of synchronous and uniform pressure.

[0019] When the electrical signal strength of one of the pressure regulating molding units is too high, it indicates that the compression of the pressure regulating element in that group is too large and the corresponding pressing force is too high. The control system controls the suction device to evacuate the regulating chamber of that unit, so that the regulating chamber and the sliding chamber connected to it form a negative pressure, causing the piston rod to retract into the sliding chamber. After the piston rod retracts, the pressure of the pressure regulating element on the force transmission shell decreases. Under the action of the rebound force of the first elastic element, the upper constant temperature pressure plate is slightly raised, thereby reducing the pressing force of the unit on the outer wall panel and avoiding glue overflow and decorative layer slippage due to excessive local pressure, which would affect the molding quality.

[0020] When the electrical signal strength of a certain pressure regulating molding unit is too low, it indicates that the compression of the pressure regulating element in that group is insufficient and the corresponding pressing force is too small. The control system then controls the suction device to add air to the regulating chamber of the corresponding unit, so that the pressure inside the regulating chamber and the sliding chamber connected to it increases, pushing the piston rod to extend outward. After the piston rod extends, the pressure regulating element further applies pressure to the force transmission shell, so that the pressing force of the upper constant temperature pressure plate on the inner and outer wall panels of the unit increases, thereby avoiding the problem of glue bubbling and poor adhesion of the decorative layer due to insufficient local pressure.

[0021] By combining the detection element and the pressure regulating element, each pressure regulating molding unit is independently detected and adjusted and compensated, so that the corresponding exterior wall panel of each unit can obtain a relatively consistent pressing force, thereby improving the consistency of the molding thickness and molding quality of the exterior wall panel.

[0022] Furthermore, the pressure equalization mechanism includes a pressure rod, on which several positioning pressure plates are equally spaced. The positioning pressure plates are fitted with the pressure transmission component. The pressure rod is installed at the bottom of the pressing component. The pressure rod is slidably connected to the pressure transmission component and to the lower constant temperature support plate. The pressure rod passes through the first elastic element.

[0023] As the pressing component moves downward, it drives the pressure rod to descend synchronously. The pressure rod slides down along the first and second positioning holes, further driving several positioning pressure plates to move downward synchronously. The positioning pressure plates engage with the positioning grooves on the pressure transmission components through interlocking strips. Under the combined limiting and guiding action of the first positioning hole, the second positioning hole, and the positioning groove, the pressure equalizing mechanism can maintain stable movement during the pressing process, reducing deviation and making the pressing position more accurate. As the pressing component continues to press down, the pressure rod drives several positioning pressure plates to simultaneously apply extrusion pressure to several sets of pressure transmission components, thereby evenly distributing the downward pressure of the pressing component to each pressure regulating forming unit. This ensures that each pressure regulating forming unit receives a basically uniform pressing force, achieving uniform pressing, ensuring that each exterior wall panel is subjected to consistent pressure, and improving the consistency of the finished product.

[0024] Furthermore, the pressure transmission component is provided with a wing plate, which is connected to the force transmission slide plate. The pressure transmission component is provided with a positioning groove, and the bottom end of the positioning pressure plate is provided with an interlocking strip, which is interlocked with the positioning groove. The pressure transmission component is provided with a second positioning hole, and the pressure rod is slidably connected to the pressure transmission component through the second positioning hole.

[0025] After being pressed, the pressure transmission component transmits the pressure to the force transmission slide plate through the wing plate. The force transmission slide plate then moves downwards and applies further pressure to the force transmission shell through several pressure regulating elements. The pressure on the force transmission shell causes the upper thermostatic pressure plate to move downwards, gradually compressing the first elastic element until the upper thermostatic pressure plate forms a stable pressure on the outer wall panel. At this point, the control system stops the hydraulic device from continuing to operate and maintains a continuous downward pressure, thus allowing the upper thermostatic pressure plate and the lower thermostatic support plate to jointly and stably press the outer wall panel, achieving the pressing and forming of the outer wall panel.

[0026] Furthermore, positioning plates are installed at both ends of the lower constant temperature support plate, and the positioning plates are provided with first positioning holes. The pressure rod is slidably connected to the positioning plates through the first positioning holes. A second constant temperature channel is provided inside the lower constant temperature support plate, and a constant temperature device is connected to the outside of the second constant temperature channel.

[0027] Furthermore, the upper constant temperature plate is provided with a first constant temperature channel, which is connected to the constant temperature device.

[0028] The thermostatic device supplies heating medium through pipes to the inlets of the first and second thermostatic channels. The heating medium flows within these channels, heating both the upper and lower surfaces of the exterior wall panel, thus accelerating adhesive coagulation and eliminating the problem of prolonged adhesive drying time caused by low temperatures. After heat exchange with the exterior wall panel, the heating medium returns from the outlets of the first and second thermostatic channels to the thermostatic device, where it is reheated before entering the next heat exchange cycle.

[0029] After the upper constant temperature plate and the lower constant temperature support plate press the outer wall panel, the control system activates the constant temperature device. The constant temperature device delivers heating medium into the upper constant temperature plate and the lower constant temperature support plate, so that the upper constant temperature plate and the lower constant temperature support plate heat the outer wall panel, thereby accelerating the molding process.

[0030] Compared with the prior art, the beneficial effects of the present invention are: 1. Through multiple limiting and guiding mechanisms, the pressing process of the pressure equalization mechanism is made more stable and accurate, avoiding deviation; at the same time, several positioning pressure plates are used to transmit force to several groups of pressure transmission components synchronously, so as to evenly distribute the downward pressure of the pressing components to each pressure regulating and forming unit, thereby achieving consistent pressure on each exterior wall panel and improving the consistency of finished products.

[0031] 2. The heating medium is circulated and delivered to the upper and lower constant temperature pressure plates and the lower constant temperature support plates through a constant temperature device, so as to heat the upper and lower surfaces of the exterior wall panel simultaneously. Under the pressing state, the drying speed of the glue is accelerated, the molding cycle is shortened, the adverse effects of low temperature environment on glue curing are reduced, and the molding efficiency and finished product quality stability of the exterior wall panel are improved.

[0032] 3. By detecting the synchronous displacement of the detection element during the pressure adjustment process of the pressure regulating element, the displacement of the detection slide bar is converted into an electrical signal using the LVDT sensing principle, enabling the control system to determine the compression amount of each pressure regulating molding unit in real time.

[0033] 4. The control system can detect units with excessive or insufficient local pressure by synchronously acquiring and comparing the electrical signals output by several groups of pressure regulating molding units. It can then independently compensate and adjust the corresponding regulating chambers by means of air extraction or air replenishment, thereby keeping the pressing force of each unit within the set range and achieving synchronous pressure uniformity.

[0034] 5. By independently testing and adjusting each pressure-regulating molding unit, problems such as glue overflow and decorative layer slippage caused by excessive local pressure, as well as glue bubbling and loose bonding caused by insufficient local pressure, can be effectively avoided, thereby improving the consistency of the thickness of the exterior wall panel and the overall molding quality.

[0038] Example: Figures 1-10 As shown, the present invention provides a technical solution: a rapid prototyping production equipment for prefabricated building exterior wall panels, including a pressure holding bracket 1 and several pressure regulating forming units 5. Several hydraulic devices 2 are installed on the pressure holding bracket 1, and a pressing component 3 is installed on the output shaft of the hydraulic device 2. A pressure equalizing mechanism 6 is symmetrically installed at the bottom end of the pressing component 3, and several lateral support components 4 are installed at the bottom end of the pressure holding bracket 1. The pressure regulating molding unit 5 includes a lower constant temperature support plate 52, a first elastic element 53, and an upper constant temperature pressure plate 51. Several lower constant temperature support plates 52 are equidistantly installed on the lateral support member 4. Pressure regulating connectors 55 are symmetrically installed at both ends of the upper constant temperature pressure plate 51. Pressure transmitting members 54 are installed on the pressure regulating connectors 55. The pressure transmitting members 54 are slidably connected to the pressure equalization mechanism 6. The pressure equalization mechanism 6 is slidably connected to the lower constant temperature support plate 52. The top end of the first elastic element 53 is connected to the pressure transmitting member 54, and the bottom end of the first elastic element 53 is connected to the lower constant temperature support plate 52.

[0039] The molding production equipment is connected to an external control box, which contains a control system for operating the entire molding production equipment. The exterior wall panel consists of an insulation layer and a decorative surface. First, adhesive is applied to both sides of the insulation layer, and then the decorative surface is attached to the adhesive surface to form a semi-finished exterior wall panel to be molded.

[0040] The first elastic element 53 is a first spring, used to provide support for the upper thermostatic pressure plate 51 when not in operation, keeping the upper thermostatic pressure plate 51 separated from the lower thermostatic support plate 52. At the same time, it also provides a restoring force for the upper thermostatic pressure plate 51 to return to its original position after operation.

[0041] The pressure equalization mechanism 6 includes a pressure rod 61, on which several positioning pressure plates 62 are installed at equal intervals. The positioning pressure plates 62 are fitted with the pressure transmission component 54. The pressure rod 61 is installed at the bottom of the pressing component 3. The pressure rod 61 is slidably connected to the pressure transmission component 54. The pressure rod 61 is slidably connected to the lower constant temperature support plate 52. The pressure rod 61 passes through the first elastic component 53.

[0042] The pressure transmission component 54 is provided with a wing plate 541, which is connected to the force transmission slide plate 552. The pressure transmission component 54 is provided with a positioning groove 542. The bottom end of the positioning pressure plate 62 is provided with an interlocking strip 621, which is interlocked with the positioning groove 542. The pressure transmission component 54 is provided with a second positioning hole 543, and the pressure rod 61 is slidably connected to the pressure transmission component 54 through the second positioning hole 543.

[0043] The pressure regulating connector 55 includes a force transmission shell 551, a detection cavity 5511 inside the force transmission shell 551, the force transmission shell 551 is installed at both ends of the upper constant temperature pressure plate 51, a force transmission slide plate 552 is slidably installed inside the force transmission shell 551, a detection element 553 is installed inside the force transmission slide plate 552, the bottom end of the detection element 553 abuts against the bottom end of the detection cavity 5511, and a plurality of pressure regulating elements 554 are installed inside the force transmission slide plate 552, the bottom end of the pressure regulating elements 554 abuts against the bottom end of the detection cavity 5511.

[0044] The force transmission slide plate 552 is provided with an adjustment cavity 5523. Connectors 5521 are installed at both ends of the adjustment cavity 5523. The connectors 5521 are connected to a suction device through a pipe. The force transmission slide plate 552 is provided with several sliding cavities 5522. The sliding cavities 5522 are connected to the adjustment cavity 5523. The pressure regulating element 554 includes a piston rod 5542, which is slidably installed in a sliding cavity 5522. A second elastic element 5543 is provided in the sliding cavity 5522. The top end of the second elastic element 5543 is connected to the top end of the sliding cavity 5522, and the bottom end of the second elastic element 5543 is connected to the top end of the piston rod 5542. A push head 5541 is installed at the bottom end of the piston rod 5542, and the push head 5541 abuts against the bottom end of the detection cavity 5511.

[0045] The suction device is connected to the regulating chamber 5523 via a pipe. The suction device can inject air into the regulating chamber 5523 through the connector 5521, pressurizing the regulating chamber 5523 and the connected sliding chamber 5522, thus pushing the piston rod 5542 out of the sliding chamber 5522. Alternatively, the suction device can extract air from the regulating chamber 5523, creating a negative pressure in the regulating chamber 5523 and the sliding chamber 5522, causing the piston rod 5542 to retract into the sliding chamber 5522. The second elastic element 5543 is a second spring.

[0046] The detection element 553 includes a detection slide rod 5531 and an induction coil 5532. The detection slide rod 5531 is slidably mounted inside the force transmission slide plate 552. A detection spring 5533 is installed between the detection slide rod 5531 and the force transmission slide plate 552. The induction coil 5532 is installed inside the force transmission slide plate 552. An iron core is provided inside the detection slide rod 5531, and the iron core is located inside the induction coil 5532. The detection spring 5533 is used to drive the detection slide rod 5531, which is retracted into the force transmission slide plate 552, to spring back to its original position.

[0047] The induction coil 5532 consists of a primary coil and a secondary coil. The induction coil 5532, together with the iron core, forms the LVDT sensor structure.

[0048] Positioning plates 522 are installed at both ends of the lower constant temperature support plate 52. The positioning plates 522 are provided with first positioning holes 523. The pressure rod 61 is slidably connected to the positioning plates 522 through the first positioning holes 523. The lower constant temperature support plate 52 is provided with a second constant temperature channel 521. A constant temperature device is connected to the outside of the second constant temperature channel 521.

[0049] The upper constant temperature plate 51 is provided with a first constant temperature channel 511, which is connected to the constant temperature device.

[0050] The thermostatic device supplies heating medium through pipes to the inlets of the first thermostatic channel 511 and the second thermostatic channel 521. The heating medium flows within these channels, heating both the upper and lower surfaces of the exterior wall panel, thereby accelerating the curing of the adhesive and eliminating the problem of prolonged drying time caused by low temperatures. After heat exchange with the exterior wall panel, the heating medium returns to the thermostatic device from the outlets of the first and second thermostatic channels 511 and 521, where it is reheated before entering the next heat exchange cycle.

[0051] The working principle of this invention is as follows: During operation, the semi-finished exterior wall panels to be formed are placed layer by layer on the lower constant temperature support plate 52 in each pressure regulating forming unit 5. Then, the control system turns on the hydraulic device 2. The output shaft of the hydraulic device 2 drives the pressing component 3 to descend, and the pressing component 3 drives the pressure equalizing mechanism 6 on it to descend.

[0052] When the pressing component 3 moves downward, it drives the pressure rod 61 to descend synchronously. The pressure rod 61 slides down along the first positioning hole 523 and the second positioning hole 543, and further drives several positioning pressure plates 62 to move downward synchronously. The positioning pressure plates 62 are engaged with the positioning grooves 542 on the pressure transmission component 54 through the interlocking strips 621. Under the combined limiting and guiding action of the first positioning hole 523, the second positioning hole 543 and the positioning groove 542, the pressure equalizing mechanism 6 can maintain stable movement during the pressing process, reduce deviation, and make the pressing position more accurate. As the pressing component 3 continues to press down, the pressure rod 61 drives several positioning pressure plates 62 to apply extrusion force to several sets of pressure transmission components 54 simultaneously, thereby evenly distributing the downward pressure of the pressing component 3 to each pressure regulating forming unit 5, so that each pressure regulating forming unit 5 is subjected to basically the same pressing force, achieving uniform pressing, ensuring that each exterior wall panel is under consistent pressure, and improving the consistency of the finished product.

[0053] After being pressed, the pressure transmission component 54 transmits the pressure to the force transmission slide plate 552 through the wing plate 541. The force transmission slide plate 552 then moves downward and further applies pressure to the force transmission shell 551 through several pressure regulating elements 554. After being pressed, the force transmission shell 551 drives the upper constant temperature pressure plate 51 to move downward, so that the first elastic element 53 is gradually compressed until the upper constant temperature pressure plate 51 forms a stable pressure on the outer wall panel. At this time, the control system controls the hydraulic device 2 to stop its operation and keeps the hydraulic device 2 in a continuous downward pressure state, so that the upper constant temperature pressure plate 51 and the lower constant temperature support plate 52 work together to stably press the outer wall panel to achieve the pressing and forming of the outer wall panel.

[0054] When the force-transmitting slide plate 552 transmits pressure to the force-transmitting shell 551 through the pressure regulating element 554, the force-transmitting slide plate 552 first presses down on the second elastic element 5543. After being pressed, the second elastic element 5543 pushes the piston rod 5542 downward. The piston rod 5542 then applies downward pressure to the detection chamber 5511 of the force-transmitting shell 551 through the push head 5541. Since the force-transmitting shell 551 is connected to the upper thermostatic pressure plate 51, and the upper thermostatic pressure plate 51 is supported upward by the first elastic element 53, when the push head 5541 presses down on the force-transmitting shell 551, the piston rod 5542 is not only subjected to the downward force from the force-transmitting slide plate 552 and the second elastic element 5543, but also to the upward reaction force generated by the first elastic element 53 transmitted through the upper thermostatic pressure plate 51 and the force-transmitting shell 551. Under the combined influence of the upper and lower forces, the piston rod 5542 will retract relatively within the sliding cavity 5522, and the second elastic element 5543 will also be compressed accordingly. As the pressure equalization mechanism 6 remains in a pressing state under the action of the hydraulic device 2 and does not produce further displacement, the corresponding pressure transmission component 54 and force transmission slide plate 552 also no longer produce displacement. As the pressure regulating element 554 contracts, the force transmission shell 551 slides upward along the force transmission slide plate 552. Furthermore, the greater the pressure applied by the hydraulic device 2, the greater the pressure applied by the force transmission slide plate 552 to the pressure regulating element 554, the greater the compression of the second elastic element 5543, and the corresponding increase in the upward displacement of the force transmission shell 551 along the force transmission slide plate 552.

[0055] During the compression and contraction of the pressure regulating element 554, as the force transmission shell 551 and the force transmission slide plate 552 approach each other, the detection element 553 is simultaneously compressed. The detection slide rod 5531 gradually retracts into the force transmission slide plate 552, causing the detection spring 5533 to compress. Simultaneously with the contraction of the detection slide rod 5531, its internal iron core displaces relative to the induction coil 5532 and passes through the induction coil 5532. According to the principle of the LVDT sensor, when the iron core moves within the induction coil 5532, the magnetic flux of the induction coil 5532 changes, outputting an electrical signal corresponding to the displacement of the iron core. The control system determines the displacement of the detection slide rod 5531 based on the strength of the electrical signal output by the induction coil 5532. The greater the displacement, the greater the compression of the pressure regulating element 554, and the greater the pressure exerted on the corresponding pressure regulating element 554.

[0056] The control system synchronously collects and compares the electrical signals output by several groups of pressure regulating molding units 5 one by one. When the intensity of each group of electrical signals is within the error range of the set standard value, it indicates that the pressure applied by several groups of pressure regulating molding units 5 to the corresponding outer wall panels is basically the same, thereby achieving the effect of synchronous and uniform pressure.

[0057] When the electrical signal strength of one of the pressure regulating molding units 5 is too high, it indicates that the compression of the pressure regulating element 554 is too large and the corresponding pressing force is too high. The control system controls the suction device to evacuate the regulating chamber 5523 of the unit, so that the regulating chamber 5523 and the sliding chamber 5522 connected to it form a negative pressure, causing the piston rod 5542 to retract into the sliding chamber 5522. After the piston rod 5542 retracts, the pressure of the pressure regulating element 554 on the force transmission shell 551 is reduced. Under the action of the rebound force of the first elastic element 53, the upper constant temperature pressure plate 51 is slightly raised, thereby reducing the pressing force of the unit on the outer wall panel and avoiding glue overflow and decorative layer slippage due to excessive local pressure, which would affect the molding quality.

[0058] When the electrical signal strength of one of the pressure regulating molding units 5 is too low, it indicates that the compression of the pressure regulating element 554 is insufficient and the corresponding pressing force is too small. The control system then controls the suction device to add air to the regulating chamber 5523 of the corresponding unit, so that the internal pressure of the regulating chamber 5523 and the sliding chamber 5522 connected to it increases, pushing the piston rod 5542 to extend outward. After the piston rod 5542 extends, the pressure regulating element 554 further applies pressure to the force transmission shell 551, so that the pressing force of the upper constant temperature pressure plate 51 on the inner and outer wall panels of the unit increases, thereby avoiding the problem of glue bubbling and poor adhesion of the decorative layer due to insufficient local pressure.

[0059] By cooperating with the detection element 553 and the pressure regulating element 554, each pressure regulating molding unit 5 is independently detected and independently adjusted and compensated, so that the corresponding exterior wall panels of each unit can obtain a relatively consistent pressing force, thereby improving the consistency of the molding thickness and molding quality of the exterior wall panels.

[0060] After the upper constant temperature plate 51 and the lower constant temperature support plate 52 press the outer wall panel, the control system activates the constant temperature device. The constant temperature device delivers heating medium into the upper constant temperature plate 51 and the lower constant temperature support plate 52, so that the upper constant temperature plate 51 and the lower constant temperature support plate 52 heat the outer wall panel, thereby achieving the purpose of accelerating the molding.

[0061] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
