Description

Technical Field

[0001] The present invention belongs to the technical field of hot pressing devices, and in particular relates to a building template hot pressing device and a use method thereof. Background Art

[0002] Building formwork is a temporary board material used to support and shape concrete structures during concrete pouring construction. It is usually made of materials such as multi-layer plywood or bamboo plywood through a specific process. It has the characteristics of smooth surface, high strength and a wide turnover rate. The building formwork hot pressing device is a device specifically used to hot-press the raw materials for formwork production into shape.

[0003] In actual use, the existing building formwork hot pressing device can fill the bonding surfaces of the multiple layers of plywood with adhesive, and then stack the multiple layers of plywood on multiple movable placement tables in sequence. At this time, one of the screw motors can be used to drive a movable placement table on its top to move to the bottom of the hot pressing assembly, and then the hot pressing descending plate can be driven down by the action of the hydraulic cylinder to perform hot pressing on the multiple layers of plywood. After processing one building formwork, the processed building formwork can be moved away from the hot pressing assembly by the screw motor, and another movable placement table carrying the multiple layers of plywood can be moved to the bottom of the hot pressing assembly for hot pressing. This multi-station processing method can greatly improve the hot pressing effect efficiency of the hot pressing formwork and reduce the time waste caused by its actual processing.

[0004] The hot pressing components in the existing hot pressing device adopt a one-way pressure structure, which uses a hydraulic cylinder to vertically extrude the template. However, the one-way pressure method is difficult to form effective pressure on the edges and corners of the template, resulting in uneven glue penetration inside the template, which is prone to local accumulation or glue deficiency. At the same time, it is impossible to eliminate "dead corner bubbles" formed by air retention between layers. These problems will directly lead to fatal defects such as delamination and hollowing in the template during use, seriously affecting its mechanical properties and service life.

[0005] Therefore, in view of the above status quo, there is an urgent need to develop a building template hot pressing device and a method of using the same to overcome the shortcomings in current practical applications. Summary of the Invention

The connecting holes cooperate with the connecting pins to connect the auxiliary leg and the main leg as a whole and limit the lengths of the two to remain unchanged during the extension process.

[0019] As a further technical solution of the present invention, the extrusion mechanism includes:

[0020] Vertical brackets are symmetrically fixed on the left and right sides of the device body, and the two vertical brackets are respectively vertically slidably connected to the left and right sides of the plurality of hot plates;

[0026] The linkage guide pillars are symmetrically arranged on the left and right sides of the extrusion plate, and the two linkage guide pillars on the same side are fixedly connected to one end of the two extrusion plates respectively;

[0027] The linkage racks are installed on the end surfaces of the two linkage guide pillars located on the same side that are close to each other. The two linkage racks located on the same side are respectively engaged with the two sides of the same linkage gear.

[0028] As a further technical solution of the present invention, the height limiting mechanism includes:

[0029] Limiting plates fixed on the four corners of the hot pressing plate;

[0030] A limiting sleeve is vertically fixed on the limiting plate, and a limiting guide groove is vertically provided on the inner wall of the limiting sleeve;

[0031] A limiting guide post that is slidably engaged with the limiting guide groove, wherein both the limiting sleeve and the limiting guide post are provided with equidistantly arranged matching holes;

[0032] A limiting ring is fixed on one end of the limiting guide pin, and the limiting ring is in intermittent contact with the adjacent hot pressing plate.

[0033] As a further technical solution of the present invention, installation grooves are distributed on the hot pressing plate, and limiting grooves are provided on the upper and lower sides of the installation grooves. The installation grooves and the limiting grooves are both used for the installation of the jacking mechanism, and the jacking mechanism quickly lifts the template on the hot pressing plate through its own elastic expansion and contraction.

[0034] As a further technical solution of the present invention, the jacking mechanism includes:

[0035] Lifting plates are distributed on the upper and lower sides of the hot pressing plate and intermittently cooperate with the limiting grooves, and one side of the lifting plate is connected to the inner wall of the installation groove through a lifting spring;

[0036] A jacking rack fixed to one side of the jacking plate, one end of the jacking rack extending into the mounting groove;

[0037] The jacking gear installed in the installation groove is rotated by the jacking shaft, and two sides of the jacking gear in the same installation groove are respectively meshed with two jacking racks distributed on the upper and lower sides thereof.

[0038] A method for using the above-mentioned building template hot pressing device comprises the following specific steps:

[0039] 1. In the initial state, the return spring drives the two adjacent hot pressing plates away from each other through its own elastic force, and the height limit mechanism adjusts the extrusion thickness of the hot pressing plate on the template by moving up and down;

[0040] Second, place the template to be hot-pressed on the hot pressing plate, and the rolling block drives the main support leg, the auxiliary support leg, the pressing piece and the installation cylinder to move downward synchronously. The auxiliary support leg drives the rolling wheel to move downward, and the rolling wheel applies pressure to the extrusion plate at the top and drives it to move downward synchronously. The extrusion plate at the top drives the linkage guide column on it to move downward synchronously. The linkage guide column drives the linkage gear to rotate through the linkage rack on it, and the linkage gear drives another linkage guide column to move upward synchronously through the linkage rack meshed with the other side. The linkage guide column drives the extrusion plate at the bottom to move upward synchronously. The two extrusion plates drive the multiple hot pressing plates inside them to move toward the middle direction of the extrusion mechanism through mutual cooperation. The multiple hot pressing plates achieve hot pressing treatment on the template by moving toward the middle direction of the extrusion mechanism. At this time, the external resistance encountered by the extension spring is less than its own elastic force and no deformation or other problems will occur.

[0041] 3. When the hot pressing plate is hot pressing the template, the space between the two adjacent hot pressing plates is continuously reduced, and the two hot pressing plates squeeze the jacking plate in the space through the template, and the jacking plate in the space moves toward the limit groove, and the jacking plate in the space drives the jacking gear to rotate through the jacking rack, and the jacking gear drives the jacking plate in the adjacent space to move back to the limit groove synchronously through the jacking rack distributed on the other side; when the height limiting mechanism moves to the position of contact with the adjacent hot pressing plate, the hot pressing plate reaches the preset hot pressing limit position, at this time the extrusion mechanism, hot pressing plate and height limiting mechanism are all in a stationary state, and the two extrusion plates at the top and bottom are in full contact with the adjacent hot pressing plates, and the extrusion mechanism, hot pressing plate and template form a tightly fitted and stacked fixed overall structure;

[0042] The hydraulic component continues to work and continues to apply downward pressure to the rolling block by cooperating with the extrusion mechanism in a static state. At this time, the external resistance encountered by the extension spring is greater than its own elastic force and deforms, and the pressing component slides toward the direction close to the mounting cylinder. At the same time, the rolling block applies downward pressure to the main support leg and drives it to rotate. The main support leg drives the rolling wheel through the auxiliary support leg to apply rolling force to the extrusion plate in the horizontal, longitudinal and diagonal directions. The rolling force applied to the extrusion plate in multiple directions is evenly transmitted to the hot pressing plate and the template through the rigid contact surface. The template is forced to evenly penetrate the glue inside the template in multiple directions through the rolling force applied to it in multiple directions and eliminate residual bubbles on the edges or corners of the template.

[0043] 4. When the hot pressing plate completes the hot pressing of the template, the hydraulic parts work in the reverse direction and release the pressure on the extrusion plate and the hot pressing plate. The return spring releases its own elastic force and drives the two adjacent hot pressing plates away from each other. The hot pressing plate releases the extrusion of the lifting plate by moving away from each other. The positioning spring releases its own elastic force and drives the lifting plate out of the limit groove. The lifting plates distributed on the upper and lower sides of the same hot pressing plate lift the templates in the upper and lower hot pressing spaces by moving away from each other.

[0044] Compared with the prior art, the present invention has the following beneficial effects:

[0045] In the initial state, the return spring drives the adjacent hot pressing plates away from each other through its own elastic force, forming a space that allows the template to enter, so that the template can be placed without obstruction. At the same time, the height limit mechanism adjusts the extrusion thickness of the hot pressing plate on the template by moving up and down, so that the hot pressing plate can accurately press it to the required thickness, avoiding damage to the template caused by excessive extrusion, and reducing the production scrap rate;

[0046] The hydraulic parts drive the rolling block to move downward, and the rolling block, carrying the stretching component and the rolling wheel, moves downward synchronously and applies pressure to the top of the extrusion mechanism, driving its top to move downward and its bottom to move upward, thereby driving the internal hot pressing plate to move toward the middle of the extrusion mechanism, reducing the distance between adjacent hot pressing plates to achieve template hot pressing treatment; when the height limiting mechanism moves to contact with the adjacent hot pressing plate, the hot pressing plate reaches the preset hot pressing limit position, at this time the extrusion mechanism, the hot pressing plate and the height limiting mechanism are stationary, and the top and bottom of the extrusion mechanism and the adjacent hot pressing plates are fully in contact with the template, so as to form a tightly fitting stacked fixed whole, thereby ensuring the mold Hot pressing quality of the plate; as the hydraulic parts continue to work, they drive the stretching assembly to stretch between the rolling block and the extrusion mechanism, so that the rolling wheel applies rolling force along the horizontal, vertical and diagonal directions of the extrusion mechanism. This force is evenly transmitted to the hot pressing plate and the template through the rigid contact surface, which can promote the multi-directional and uniform penetration of the glue in the template, avoid local accumulation or lack of glue, and eliminate residual bubbles at the edges and corners, solve the "dead corner bubble" problem of traditional unidirectional pressure, and eliminate defects such as template delamination and hollowing from the root, thereby improving its production quality and the hot pressing efficiency and quality of the device.

DETAILED DESCRIPTION

[0061] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0062] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0063] like Figures 1 to 9As shown, as an embodiment of the present invention, a building template hot pressing device is provided, which includes a device body 100, an extrusion mechanism 200, a hot pressing plate 300 and a hydraulic component 400. The extrusion mechanism 200 is symmetrical and fixedly arranged inside the device body 100. A plurality of hot pressing plates 300 are vertically stacked in the extrusion mechanism 200. The left and right sides of the hot pressing plates 300 are vertically slidably connected to the extrusion mechanism 200. Heaters 310 for heating the template are installed on the upper and lower sides of the hot pressing plates 300, and a return spring 600 is installed between two adjacent hot pressing plates 300. The hydraulic component 400 is fixed to the top of the device body 100 and is connected to the extrusion mechanism 200. It also includes:

[0064] Height limiting mechanisms 800, which are distributed at the four corners of a single hot pressing plate 300 and are located inside the return spring 600. The top of the height limiting mechanism 800 intermittently engages with the bottom of an adjacent hot pressing plate 300;

[0065] The rolling mechanism 500 includes a rolling block 510, an extension assembly 520, and a rolling wheel 530. The rolling block 510 is located above the extrusion mechanism 200 and is fixedly connected to the output end of the hydraulic component 400. One side of the rolling block 510 is circumferentially distributed with mounting grooves 511, and the other side of the rolling block 510 is circumferentially distributed with mounting guide grooves 512 that are consistent in number and position with the mounting grooves 511. One end of the mounting guide groove 512 is connected to the mounting groove 511. One end of the extension assembly 520 is respectively installed in the mounting groove 511 and the mounting guide groove 512. The other end of the extension assembly 520 is installed with a rolling wheel 530 that contacts the top of the extrusion mechanism 200, and the rolling wheels 530 are circumferentially distributed in the transverse, longitudinal, and diagonal directions of the top of the extrusion mechanism 200.

[0066] In the initial state, the return spring 600 drives the two adjacent hot pressing plates 300 away from each other through its own elastic force to ensure that there is enough space between the two to meet the template's entry requirements and ensure that the template can be placed on the hot pressing plate 300 without obstruction. The height limiting mechanism 800 can adjust the extrusion thickness of the hot pressing plate 300 on the template by moving up and down, so that the hot pressing plate 300 can accurately press the template to its required thickness. At the same time, it can avoid damage to the template due to excessive extrusion of the hot pressing plate 300, reduce the production scrap rate of the template, and improve the hot pressing efficiency and quality of the device.

[0067] The template to be hot-pressed is placed on the hot pressing plate 300, and the hydraulic component 400 drives the rolling block 510 to move downward, and the rolling block 510 drives the stretching component 520 and the rolling wheel 530 to move downward synchronously, and the stretching component 520 and the rolling wheel 530 apply pressure to the top of the extrusion mechanism 200 and drive it to move downward synchronously. The top of the extrusion mechanism 200 can drive its bottom to move upward synchronously by moving downward, and the extrusion mechanism 200 can drive the multiple hot pressing plates 300 located inside it to move toward the middle of the extrusion mechanism 200 by moving the top downward and the bottom upward. By moving toward the middle of the extrusion mechanism 200, the multiple hot pressing plates 300 can not only drive their respective height limiting mechanisms 800 to move synchronously, but also reduce the distance between two adjacent hot pressing plates 300, thereby achieving hot pressing treatment of the template;

[0068] When the height limiting mechanism 800 moves to a position where it contacts the adjacent hot pressing plate 300, the hot pressing plate 300 reaches a preset hot pressing limit position. At this time, the extrusion mechanism 200, the hot pressing plate 300 and the height limiting mechanism 800 are all in a stationary state, and the top and bottom of the extrusion mechanism 200 are fully in contact with the adjacent hot pressing plate 300, and the adjacent hot pressing plates 300 are fully in contact with each other through the template. This not only ensures the hot pressing quality of the hot pressing plate 300 on the template, but also allows the extrusion mechanism 200, the hot pressing plate 300 and the template to form a tightly fitted and stacked fixed overall structure.

[0069] The hydraulic component 400 continues to work and, by cooperating with the extrusion mechanism 200 in a stationary state, can drive the stretching component 520 to stretch between the rolling block 510 and the extrusion mechanism 200. The stretching component 520 drives the rolling wheels 530 to stretch on the extrusion mechanism 200, so that the distributed rolling wheels 530 can apply rolling force to the extrusion mechanism 200 in the transverse, longitudinal and diagonal directions. The rolling force applied to the extrusion mechanism 200 in multiple directions can be evenly transmitted to the hot pressing plate 300 and the template through the rigid contact surface. The template is subjected to the rolling force in multiple directions, which not only forces the glue inside the template to penetrate evenly into the interior of the template in multiple directions, avoiding local accumulation or glue deficiency, but also eliminates residual bubbles on the edges or corners of the template, solving the problem of "dead corner bubbles" that are difficult to eliminate with traditional unidirectional pressure, eliminating fatal defects such as template delamination and hollowing from the root, improving the production quality of the template, and further improving the hot pressing efficiency and quality of the device.

[0070] In a preferred embodiment, during the compression of the return spring 600, the resistance encountered by the extension component 520 cannot drive it to extend until the hot pressing plate 300 reaches the preset hot pressing position and stops. At this time, the hydraulic component 400 continues to apply pressure to drive the extension component 520 to extend. It can be seen that the driving force experienced by the extension component 520 during operation is greater than the elastic force of the return spring 600.

[0071] like Figures 2 to 8 As shown, as a preferred embodiment of the present invention, the extension component 520 includes a main support leg 521, a mounting shaft 522, a secondary support leg 523, a pressing piece 526, a mounting cylinder 527 and an extension spring 528. One end of the main support leg 521 is rotatably mounted inside the mounting groove 511 through the mounting shaft 522, and the other end of the main support leg 521 is slidably mounted with the secondary support leg 523. The secondary support leg 523 is parallel to the main support leg 521, and one end of the secondary support leg 523 is mounted with a rolling wheel 530. The mounting cylinder 527 is vertically fixed in the mounting guide groove 512, and one end of the mounting cylinder 527 extends into the mounting groove 511. One end of the pressing piece 526 is vertically slidably mounted in the mounting cylinder 527 and is connected to the extension spring 528 installed in the mounting cylinder 527. The other end of the pressing piece 526 is in contact with one side of the main support leg 521.

[0072] In the initial stage when the hydraulic component 400 drives the rolling block 510 to move downward, the rolling block 510 drives the main leg 521, the auxiliary leg 523, the pressing member 526 and the installation cylinder 527 to move downward synchronously, and the auxiliary leg 523 drives the rolling wheel 530 to move downward. The rolling wheel 530 applies pressure to the top of the extrusion mechanism 200 and drives it to move downward synchronously, thereby driving the multiple hot pressing plates 300 to move toward the inside of the extrusion mechanism 200. At this time, the external resistance encountered by the extension spring 528 is smaller than its own elastic force, so that the extension spring 528 will not be deformed during the movement of the hot pressing plate 300.

[0073] When the hot pressing plate 300 reaches the preset hot pressing limit position, the extrusion mechanism 200, the hot pressing plate 300 and the template form a tightly fitted and stacked fixed overall structure. At this time, the hydraulic component 400 continues to apply downward pressure to the rolling block 510, so that the external resistance of the extension spring 528 is greater than its own elastic force and deforms, thereby causing the pressing member 526 to slide toward the mounting cylinder 527. At the same time, the rolling block 510 applies downward pressure on the main support leg 521 and drives it to rotate. The main support leg 521 drives the rolling wheel 530 to slide on the top of the extrusion mechanism 200 through the auxiliary support leg 523, and applies rolling force to it in the horizontal, longitudinal and diagonal directions of the extrusion mechanism 200, thereby realizing multi-directional rolling of the template and ensuring the hot pressing quality and efficiency of the template.

[0074] In a preferred embodiment, the pressing member 526 preferably adopts a pressing structure composed of a T-shaped column and a sphere, and the sphere directly contacts one side of the main leg 521. This not only ensures that the extension spring 528 transmits its own elastic force directly to the main leg 521 through the pressing member 526, but also reduces the friction resistance between the pressing member 526 and the main leg 521, so that the main leg 521 can complete the rotation work better and more quickly.

[0075] The main leg 521 and the auxiliary leg 523 are both provided with an equidistant array of connecting holes 524, and their distribution trajectory is consistent with the linear sliding trajectory of the two. The connecting hole 524 cooperates with the connecting pin 525 to connect the auxiliary leg 523 and the main leg 521 as a whole, thereby limiting the length of the two to remain unchanged during the extension process. When it is necessary to change the overall length of the two after the connection, first release the connection state between the connecting pin 525 and the connecting hole 524, so that the auxiliary leg 523 can slide freely on the main leg 521, thereby changing the overall length of the two after the connection. This ensures that the rolling wheel 530 on each extension component 520 can effectively and fully contact the top of the extrusion mechanism 200, thereby ensuring that the rolling force can be effectively and evenly transmitted to the template, thereby improving the hot pressing quality of the template.

[0076] like Figures 2 to 5 As shown, as a preferred embodiment of the present invention, the extrusion mechanism 200 includes a vertical bracket 210, an extrusion plate 220 and a linkage assembly 230, the vertical bracket 210 is symmetrically fixed on the left and right sides of the inside of the device body 100, and the extrusion plates 220 are symmetrically arranged on the upper and lower sides of the inside of the device body 100, the two extrusion plates 220 are respectively slidably connected to the upper and lower ends of the two vertical brackets 210, and a plurality of hot pressing plates 300 are vertically stacked between the two extrusion plates 220, and the left and right sides of the plurality of hot pressing plates 300 are vertically slidably connected to the vertical bracket 210, and a linkage assembly 230 is installed on one side of the two vertical brackets 210, and the linkage assembly 230 is connected to the two extrusion plates 220, and the top end surface of the extrusion plate 220 at the top is in contact with the rolling wheel 530.

[0077] The linkage assembly 230 includes a linkage bracket 231, a linkage gear 232, a linkage rack 233 and a linkage guide column 234. The linkage bracket 231 is fixed on one side of the two vertical brackets 210 respectively, and the linkage guide columns 234 are symmetrically arranged on the left and right sides of the extrusion plate 220. The two linkage guide columns 234 on the same side are respectively fixedly connected to one end of the two extrusion plates 220, and the two linkage guide columns 234 on the same side are respectively fixedly connected to one end of the two extrusion plates 220, and the linkage racks 233 are installed on the end surfaces close to each other on the two linkage guide columns 234 on the same side. The two linkage racks 233 on the same side are respectively meshed with the two sides of the same linkage gear 232, and the linkage gear 232 is rotatably installed in the middle of the linkage bracket 231.

[0078] The template to be hot-pressed is placed on the hot-pressing plate 300, and the hydraulic component 400 drives the rolling block 510 to move downward. The rolling block 510 drives the rolling wheel 530 to move downward synchronously through the extension component 520. The rolling wheel 530 applies pressure to the extrusion plate 220 at the top and drives it to move downward synchronously. The extrusion plate 220 at the top drives the linkage guide column 234 thereon to move downward synchronously. The linkage guide column 234 drives the linkage gear 232 to rotate through the linkage rack 233 thereon. The linkage gear 232 rotates through the linkage rack 233 meshed with the other side thereof. The linkage guide column 234 drives another linkage guide column 234 to move upward synchronously, and the linkage guide column 234 drives the extrusion plate 220 at the bottom to move upward synchronously. The two extrusion plates 220 can drive the multiple hot pressing plates 300 located inside thereof to move toward the middle of the extrusion mechanism 200 by cooperating with each other. By moving toward the middle of the extrusion mechanism 200, the multiple hot pressing plates 300 can not only drive their respective height limiting mechanisms 800 to move synchronously, but also reduce the distance between two adjacent hot pressing plates 300, thereby realizing hot pressing treatment of the template.

[0079] like Figure 4 、 Figure 9 and Figure 12 As shown, as a preferred embodiment of the present invention, the height limiting mechanism 800 includes a limiting plate 810, a limiting sleeve 820, a limiting guide column 840 and a limiting ring 860. The limiting plate 810 is fixed on the four corners of the hot pressing plate 300. The limiting sleeve 820 is vertically fixed on the limiting plate 810. The inner wall of the limiting sleeve 820 is vertically provided with a limiting guide groove 830 that slides with the limiting guide column 840. The limiting sleeve 820 and the limiting guide column 840 are both provided with equidistantly arranged matching holes 850. One end of the limiting guide column 840 is fixed with a limiting ring 860 that intermittently contacts the adjacent hot pressing plate 300.

[0080] The fixing bolt or pin can be passed through the matching hole 850 to complete the fixation of the limiting sleeve 820 and the limiting guide pillar 840, so that the two are connected as a whole, thereby completing the height restriction of the limiting ring 860, ensuring that its height is constant in the working state, and further ensuring that the hot pressing plate 300 can complete the customized hot pressing of the template, ensuring the thickness of the template after hot pressing, and improving the production efficiency and production quality of the template;

[0081] After releasing the fixing bolts or pins, the limiting guide column 840 can slide freely inside and outside the limiting sleeve 820. By changing the overlapping height of the two, the limiting ring 860 can be continuously adjustable within a certain height range, and the hot pressing plate 300 can be adapted to effectively hot press templates of different thicknesses, thereby improving the applicability and convenience of the device.

[0082] In a preferred embodiment, the limiting plate 810, limiting sleeve 820 and limiting ring 860 are all concentric with the vertical bracket 210, and the inner diameters of the limiting plate 810, limiting sleeve 820, limiting guide column 840 and limiting ring 860 are all larger than the outer diameter of the vertical bracket 210, so as to avoid motion interference between the two and ensure that the hot pressing plate 300 can slide effectively and smoothly on the vertical bracket 210.

[0083] like Figures 9 to 11 As shown, as another preferred embodiment of the present invention, the hot pressing plate 300 is provided with mounting grooves 320, and the upper and lower sides of the mounting grooves 320 are provided with limiting grooves 330, and the mounting grooves 320 and the limiting grooves 330 are both used for the installation of the jacking mechanism 700. The jacking mechanism 700 can quickly lift the template on the hot pressing plate 300 through its own elastic expansion and contraction, so that it can be quickly separated from the surface of the hot pressing plate 300, which is convenient for the staff to quickly pick up and collect the template on the hot pressing plate 300, thereby improving the working efficiency of the device.

[0084] like Figures 9 to 11 As shown, the lifting mechanism 700 includes a lifting shaft 710, a lifting gear 720, a lifting rack 730, a lifting plate 740 and a lifting spring 750. The lifting plates 740 are distributed on the upper and lower sides of the hot pressing plate 300 and intermittently cooperate with the limiting groove 330. A lifting rack 730 is fixed on one side of the lifting plate 740, and one side of the lifting plate 740 is connected to the inner wall of the mounting groove 320 through a lifting spring 750. One end of the lifting rack 730 extends into the mounting groove 320. The lifting gear 720 is rotatably installed in the mounting groove 320 through the lifting shaft 710. The two sides of the lifting gear 720 in the same mounting groove 320 are respectively engaged with the two lifting racks 730 distributed on the upper and lower sides thereof.

[0085] When the hot pressing plate 300 is hot pressing the template, the space between the two adjacent hot pressing plates 300 is continuously reduced. The two hot pressing plates 300 squeeze the lifting plate 740 in the space through the template. The lifting plate 740 in the space moves toward the limiting groove 330. The lifting plate 740 in the space drives the lifting gear 720 to rotate through the lifting rack 730. The lifting gear 720 drives the lifting plate 740 in the adjacent space to move back to the limiting groove 330 synchronously through the lifting rack 720 distributed on the other side, ensuring that the surface of the hot pressing plate 300 can effectively and tightly fit the surface of the template.

[0086] When the hot pressing plate 300 completes the hot pressing of the template, the hydraulic component 400 works in the opposite direction and releases the pressure on the extrusion plate 220 and the hot pressing plate 300. The return spring 600 releases its own elastic force at this time and drives the two adjacent hot pressing plates 300 away from each other. The hot pressing plate 300 can release the extrusion of the lifting plate 740 by moving away, so that the lifting spring 750 releases its own elastic force and drives the lifting plate 740 to move out of the limit groove 330. The lifting plates 740 distributed on the upper and lower sides of the same hot pressing plate 300 can lift the template in the upper and lower hot pressing space by moving away from each other, preventing the template from adhering to the hot pressing plate 300 and making it quickly separated from the surface of the hot pressing plate 300, making it convenient for the staff to quickly pick up and collect the template on the hot pressing plate 300, thereby improving the working efficiency of the device.

[0087] In a preferred embodiment, the thickness of the lifting plate 740 is slightly less than or equal to the depth of the limiting groove 330, thereby ensuring the hot pressing quality of the template by the hot pressing plate 300, avoiding the uneven surface of the template after hot pressing, and improving the production quality of the template.

[0088] A method for using the above-mentioned building template hot pressing device comprises the following specific steps:

[0089] First, in the initial state, the return spring 600 drives the two adjacent hot pressing plates 300 away from each other through its own elastic force to ensure that there is enough space between them to meet the template's entry requirements and ensure that the template can be placed on the hot pressing plate 300 without obstruction. The height limiting mechanism 800 can adjust the extrusion thickness of the hot pressing plate 300 on the template by moving up and down, so that the hot pressing plate 300 can accurately press the template to its required thickness. At the same time, it can avoid damage to the template due to excessive extrusion of the hot pressing plate 300, thereby reducing the production scrap rate of the template;

[0090] Second, place the template to be hot-pressed on the hot pressing plate 300, and the rolling block 510 drives the main leg 521, the auxiliary leg 523, the pressing piece 526 and the installation cylinder 527 to move downward synchronously. The auxiliary leg 523 drives the rolling wheel 530 to move downward. The rolling wheel 530 applies pressure to the extrusion plate 220 at the top and drives it to move downward synchronously. The extrusion plate 220 at the top drives the linkage guide column 234 thereon to move downward synchronously. The linkage guide column 234 drives the linkage gear 232 to rotate through the linkage rack 233 thereon. The linkage gear 232 drives another linkage guide column 234 to move upward synchronously through the linkage rack 233 meshing with the other side thereof. 34 drives the extrusion plate 220 at the bottom to move upward synchronously. The two extrusion plates 220 can drive the multiple hot pressing plates 300 located inside thereof to move toward the middle of the extrusion mechanism 200 by cooperating with each other. By moving toward the middle of the extrusion mechanism 200, the multiple hot pressing plates 300 can not only drive their respective height limiting mechanisms 800 to move synchronously, but also reduce the distance between two adjacent hot pressing plates 300, thereby achieving hot pressing treatment of the template. At this time, the external resistance experienced by the extension spring 528 is smaller than its own elastic force, so that the extension spring 528 will not be deformed during the movement of the hot pressing plate 300.

[0091] 3. When the hot pressing plate 300 is hot pressing the template, the space between the two adjacent hot pressing plates 300 is continuously reduced. The two hot pressing plates 300 squeeze the lifting plate 740 in the space through the template. The lifting plate 740 in the space moves toward the limiting groove 330. The lifting plate 740 in the space drives the lifting gear 720 to rotate through the lifting rack 730. The lifting gear 720 drives the lifting plate 740 in the adjacent space to move back to the limiting groove 330 synchronously through the lifting rack 720 distributed on the other side, ensuring that the surface of the hot pressing plate 300 can be effectively Closely fit with the template surface; when the height limiting mechanism 800 moves to the position of contacting the adjacent hot pressing plate 300, the hot pressing plate 300 reaches the preset hot pressing limit position. At this time, the extrusion mechanism 200, the hot pressing plate 300 and the height limiting mechanism 800 are all in a stationary state, and the two extrusion plates 220 at the top and bottom are fully in contact with the adjacent hot pressing plates 300. This not only ensures the hot pressing quality of the hot pressing plate 300 on the template, but also allows the extrusion mechanism 200, the hot pressing plate 300 and the template to form a tightly fitted and stacked fixed overall structure;

[0092] The hydraulic component 400 continues to work and, by cooperating with the extrusion mechanism 200 in a stationary state, can continue to apply downward pressure to the rolling block 510, so that the external resistance of the extension spring 528 is greater than its own elastic force and deforms, thereby causing the pressing member 526 to slide in the direction close to the mounting cylinder 527. At the same time, the rolling block 510 applies downward pressure to the main support leg 521 and drives it to rotate. The main support leg 521 drives the rolling wheel 530 to apply rolling force to the extrusion plate 220 in the horizontal, longitudinal and diagonal directions through the auxiliary support leg 523. The rolling force applied to the extrusion plate 220 in multiple directions can be evenly transmitted to the hot pressing plate 300 and the template through the rigid contact surface. The template can be subjected to the rolling force in multiple directions, which can not only force the glue inside the template to penetrate evenly into the interior of the template in multiple directions to avoid local accumulation or glue shortage, but also eliminate residual bubbles on the edges or corners of the template, solving the problem of "dead corner bubbles" that are difficult to eliminate with traditional unidirectional pressure. The problem is solved by eliminating fatal defects such as template delamination and hollowing from the root, improving the production quality of the template and further improving the hot pressing efficiency and quality of the device;

[0093] 4. When the hot pressing plate 300 completes the hot pressing of the template, the hydraulic component 400 works in the reverse direction and releases the pressure on the extrusion plate 220 and the hot pressing plate 300. The return spring 600 releases its own elastic force at this time and drives the two adjacent hot pressing plates 300 away from each other. The hot pressing plate 300 can release the extrusion of the lifting plate 740 by moving away, so that the lifting spring 750 releases its own elastic force and drives the lifting plate 740 to move out of the limit groove 330. The lifting plates 740 distributed on the upper and lower sides of the same hot pressing plate 300 can lift the templates in the upper and lower hot pressing spaces by moving away from each other, preventing the templates from adhering to the hot pressing plate 300 and quickly separating them from the surface of the hot pressing plate 300, making it convenient for staff to quickly pick up and collect the templates on the hot pressing plate 300.

[0094] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
