Description

Technical Field

[0001] The invention relates to the technical field of prefabricated wallboard production, and in particular to a production device for assembled energy-saving prefabricated wallboards. Background Art

[0002] Ceramic tiles are usually fixed on the wall panels, which can provide good protection for the walls. As a decorative panel, ceramic tiles have a variety of textures and patterns on their surface, which can meet the needs of different people for decorative styles. In addition, ceramic tiles have a smooth surface, are easy to clean, have low water absorption, and can prevent moisture and mildew. Not only that, after the ceramic tiles are fixed on the surface of the wall panels, they also have certain thermal insulation properties, which can improve the stability of indoor temperature to a certain extent, reduce heat diffusion loss, and achieve indoor energy saving through thermal insulation.

[0003] When producing the above-mentioned prefabricated wall panels with tiles, the existing device usually pours concrete slurry into a casting mold and solidifies it into shape, and then adheres the tiles to the surface of the wall panel through cement slurry to form a wall panel product. The prefabricated wall panels produced by the above method have poor connection stability between the concrete panel and the tile surface. Especially under long-term use, they are easily affected by the external environment such as thermal expansion and contraction and rain erosion, causing some tiles to fall off; and when the tiles are fixed to the wall panels, they need to be bonded and fixed piece by piece, which has low production efficiency and is difficult to ensure the accuracy of the tile installation position, thereby affecting the product quality; not only that, in the process of producing wall panels, in order to reinforce the structural strength of the wall panels, it is necessary to place steel bars in the casting cavity, and the steel bars usually penetrate the side walls of the mold, causing part of the concrete slurry to flow into the gap between the side walls of the mold and the steel bars, affecting product demoulding and product quality.

DETAILED DESCRIPTION

[0018] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0019] like Figure 1-Figure 18 As shown, the production device of the assembled energy-saving prefabricated wallboard of the present invention comprises: The mold assembly includes a bottom mold plate 1, a side mold bar 2 and a separation and combination unit 3. The bottom mold plate 1 and the side mold bar 2 are both arranged horizontally. The separation and combination unit 3 drives the side mold bar 2 to move between a mold separation position and a mold closing position. The side mold bars 2 at the mold closing position are sequentially connected end to end and enclosed with the bottom mold plate 1 to form a casting cavity with an open top. There is a gap between the side mold bars 2 at the mold separation position. A positioning frame 4, the positioning frame 4 is horizontally arranged on one side of the mold assembly, and the top surface of the positioning frame 4 has positioning openings 41 that are distributed in sequence and arranged closely together, and the horizontal cross-section of the positioning openings 41 is adapted to the decorative plate 7; The negative pressure adsorption component 5 includes an adsorption shell 51 corresponding to the positioning port 41. The bottom surface of the adsorption shell 51 is provided with a negative pressure port 5121 connected to its inner cavity. The inner cavity of the adsorption shell 51 is connected to a negative pressure pump 52. The movable component 6 drives the negative pressure adsorption component 5 to move between the molding station and the adsorption station. At the adsorption station, each adsorption shell 51 in the negative pressure adsorption component 5 is adjacent to the top of the positioning port 41. At the molding station, the top surface of each adsorption shell 51 in the negative pressure adsorption component 5 is adjacent to the top surface of the casting cavity port and the distance difference is less than the thickness of the decorative panel 7.

[0020] When the production device is used, the decorative plate 7 is first placed in each positioning opening 41 of the positioning frame 4, with the decorative surface of the decorative plate 7 facing upward. Figure 7 As shown, since the structural position of the positioning frame 4 is fixed and the horizontal cross-sectional size of the positioning port 41 is adapted to the decorative panel 7, the positions of the positioning port 41 and the decorative panel 7 inside the positioning port 41 are relatively fixed, and then the negative pressure adsorption component 5 is adjusted to the adsorption position through the movable component 6. At the adsorption position, the negative pressure port 5121 on the bottom surface of the adsorption shell 51 in the negative pressure adsorption component 5 is adjacent to the decorative surface of the decorative panel 7, and then the negative pressure pump 52 is started, so that the adsorption shell 51 and the negative pressure port 5121 generate negative pressure, and the decorative panel 7 is firmly adsorbed under the adsorption shell 51.

[0021] At the same time, the splitting and combining unit 3 adjusts the position of the side mold strips 2 to the mold closing position. At the mold closing position, each side mold strip 2 is connected end to end in sequence to form a closed-loop frame structure, and each side mold strip 2 and the bottom mold plate 1 are enclosed to form a casting cavity with an open top, such as Figure 1-Figure 3 shown.

[0022] Afterwards, the negative pressure at the adsorption shell 51 and the negative pressure port 5121 is maintained by the negative pressure pump 52, and the position of the negative pressure adsorption component 5 is adjusted by the movable component 6, so that the negative pressure adsorption component 5 moves to the molding station. At the molding station, the top surface of the decorative plate 7 adsorbed by the adsorption shell 51, that is, the decorative surface of the decorative plate 7, is located above the cavity opening of the casting cavity, and the bottom surface of the decorative plate 7 is located below the cavity opening of the casting cavity, as shown in FIG. Figure 4 shown.

[0023] In the above case, concrete slurry is injected into the casting cavity so that the liquid surface of the concrete slurry is flush with the cavity opening of the casting cavity. During this period, the negative pressure pump 52 continues to operate to keep the relative position of the adsorption shell 51 and the decorative plate 7 fixed. After the concrete slurry is solidified to form the concrete plate 9, the decorative plate 7 is partially embedded in the concrete plate 9, and its decorative surface protrudes outward from the concrete plate 9. In this way, the decorative plate 7 is firmly connected to the concrete plate 9 to prevent the decorative plate 7 from falling off. At this time, the negative pressure pump 52 stops running, and the position of the adsorption shell 51 is adjusted by the movable component 6 to be located on one side of the mold component, and the separation unit 3 adjusts the side mold strip 2 to the separation position, so that the side mold strip 2 is separated from the concrete plate 9 solidified by the concrete slurry, which is convenient for demolding and taking out the product.

[0024] Compared with the prior art, the device can not only ensure the connection strength between the concrete slab 9 and the decorative panel 7 in the final product to prevent it from falling off, but also conveniently fix the relative positions of the decorative panels 7 through the positioning frame 4. After the negative pressure adsorption component 5 is adsorbed, the relative positions of the decorative panels 7 are fixed to avoid relative displacement, thereby ensuring accuracy and decorative effects. Moreover, the relative positions of multiple decorative panels 7 can be located through the positioning frame 4, and the negative pressure adsorption component 5 can be used to simultaneously adsorb the decorative panels 7 and move them to the mouth of the casting cavity, thereby greatly improving production efficiency.

[0025] The decorative plate 7 is a flat plate structure, and a plate such as a ceramic tile can be selected. The selection of the decorative plate 7 affects the performance of the final product. The decorative plate 7 used in the present invention has a main structure as follows: Figure 5 and Figure 6 As shown, the decorative panel 7 includes an outer decorative panel 71 and an inner panel 72 which are arranged opposite to each other. Both the outer decorative panel 71 and the inner panel 72 are square thin plates. Four connecting strips 73 which are connected end to end to form a rectangular frame are arranged between the outer decorative panel 71 and the inner panel 72. The cross section of the connecting strip 73 is U-shaped. The four connecting strips 73 are enclosed to form an embedding groove with the notch facing outward. The outer decorative panel 71, the inner panel 72 and the four connecting strips 73 are all made of aluminum alloy and are fixedly connected by resistance welding. The outer decorative panel 71, the inner panel 72 and the four connecting strips 73 are enclosed to form a thermal insulation cavity, which is filled with thermal insulation rock wool 74. The side of the outer decorative panel 71 facing away from the inner panel 72 is engraved with decorative patterns by laser grooving to ensure the decorativeness of the outer decorative panel 71.

[0026] After the decorative panel 7 adopts the above structure, when the negative pressure adsorption component 5 adsorbs the decorative panel 7 and moves to the forming position, concrete slurry is injected into the casting cavity, and the solidified concrete slurry forms a concrete panel 9. A part of the concrete panel 9 enters the embedded groove, which can further strengthen the connection strength between the decorative panel 7 and the concrete panel 9 and prevent the decorative panel 7 from falling off; not only that, the thermal insulation rock wool 74 in the thermal insulation cavity also has the functions of flame retardancy, heat insulation and sound reduction, which can enhance the functionality of the product wall panel and improve the indoor living environment; in addition, compared with the fragile and cracked characteristics of ceramic tiles, the decorative panel 7 used in the present invention, its outer decorative panel 71, inner embedded panel 72 and connecting strip 73 are all made of aluminum alloy, the structure is more stable, not easy to break and damage, and the internal filling density of the thermal insulation rock wool 74 is lower, so that the decorative panel 7 is light in material on the basis of stable structure, so as to reduce the power consumption of the negative pressure adsorption component 5 to adsorb and fix the decorative panel 7.

[0027] It should be noted that, in order to further enhance the decorative effect of the decorative panel 7, after the outer decorative panel 71, the inner panel 72, the thermal insulation rock wool 74 and the four connecting strips 73 are connected and formed, the decorative panel 7 can be subjected to surface treatment technology on the side facing away from the inner panel 72, including but not limited to spraying, electroplating and laminating, so that various textures and colors can be formed on the surface of the outer decorative panel 71 to simulate the appearance of ceramic tiles. In particular, a slurry such as a ceramic coating can be coated on the surface of the outer decorative panel 71, and the ceramic coating can be formed on the surface of the outer decorative panel 71 by a thermochemical reaction method or a slurry brushing method, which will not be described in detail here.

[0028] A further improvement is that the depth of the positioning opening 41 is less than the thickness of the decorative panel 7, and positioning strips 513 extending in the horizontal direction are arranged on the four sides of the bottom surface of the adsorption shell 51, and the positioning strips 513 are enclosed to form a positioning area, and the shape and size of the positioning area are respectively consistent with the cross-sectional shape and size of the positioning opening 41 in the horizontal direction.

[0029] After adopting the above structure, the decorative panel 7 is placed at the positioning opening 41, and the top of the decorative panel 7 protrudes from the top surface of the positioning frame 4. After the negative pressure adsorption component 5 adsorbs the decorative panel 7, the circumferential outer edge of the decorative panel 7 is in contact with the positioning strip 513. The positioning strip 513 limits the horizontal position of the decorative panel 7 to prevent the decorative panel 7 from being affected by other forces such as the flow of the concrete slurry during the injection of concrete slurry and the vibration of the concrete slurry, thereby preventing the horizontal position deviation of the decorative panel 7 caused by other forces such as the flow of the concrete slurry, which ultimately affects the position accuracy of the decorative panel 7 on the product surface and reduces the product quality.

[0030] The specific structure of the positioning frame 4 is as follows Figure 7As shown, the positioning frame 4 includes a rectangular outer frame 42, and the length and width dimensions of the circumferential inner wall of the outer frame 42 are respectively smaller than the length and width dimensions of the casting cavity. The outer frame 42 is integrally connected with horizontal bars 43 that are evenly spaced along its own length direction and extend along its own width direction, and vertical bars 44 that are evenly spaced along its own width and extend along its own length direction. The horizontal bars 43 and the vertical bars 44 are vertically cross-fixed and connected. The intervals between adjacent horizontal bars 43 and the intervals between adjacent vertical bars 44 are consistent with the side length dimensions of the embedded panel 72. The bottoms of adjacent horizontal bars 43 and the bottoms of adjacent vertical bars 44 are fixedly connected by a bottom bracket 45. In this way, a positioning opening 41 is formed by enclosing adjacent horizontal bars 43, adjacent vertical bars 44 and the bottom bracket 45. The depth of the positioning opening 41 is smaller than the thickness of the decorative panel 7. Finally, on the positioning frame 4, the positioning openings 41 are distributed in a rectangular array, and adjacent positioning openings 41 are arranged closely.

[0031] Of course, according to actual production needs, the shape of the positioning frame 4 can be adjusted accordingly, and the positioning opening 41 can also adopt other shapes and distribution methods. For example, the cross-section of the positioning opening 41 and the decorative panel 7 are both regular hexagons and the positioning opening 41 adopts a honeycomb distribution method, which can also achieve the technical effect of the present invention, that is, the relative positions of multiple decorative panels 7 are fixed at one time to ensure product accuracy and quality.

[0032] A further improvement is that the depth of the positioning area is less than or equal to the difference between the thickness of the decorative plate 7 and the depth of the positioning opening 41 .

[0033] In the present invention, the depth of the positioning area is smaller than the difference between the thickness of the decorative panel 7 and the depth of the positioning opening 41. In this way, when the negative pressure adsorption assembly 5 moves to the molding position, the positioning strip 513 on the bottom surface of the adsorption shell 51 maintains a certain distance from the plane where the cavity opening of the casting cavity is located, thereby avoiding contact between the positioning strip 513 and the concrete slurry in the casting cavity.

[0034] like Figure 16-Figure 18 As shown, the negative pressure pump 52 is fixedly connected to a plurality of adsorption shells 51 distributed in a rectangular array through a connecting pipe 521. The negative pressure pump 52 and the connecting pipe 521 are both fixed on the top of the adsorption shell 51. The adsorption shell 51 comprises a shell 511 in a hood shape and a shell bottom 512 fixedly covered at the bottom of the shell 511. The negative pressure ports 5121 are arranged in a rectangular array and densely distributed on the shell bottom 512. The projection of the shell bottom 512 on the horizontal plane is a square. The four sides of the shell bottom 512 are fixedly connected with positioning strips 513. The positioning strips 513 extend along the length direction of the corresponding side of the shell bottom 512 and have an L-shaped cross section. A positioning area is formed by the positioning strips 513 on the four sides. When the decorative panel 7 is adsorbed and fixed, the positioning strips 513 on the four sides are sealed and fitted with the four side edges of the outer decorative panel 71 of the decorative panel 7, as shown in FIG. Fig.16 As shown, this prevents the exterior trim panel 71 from being affected by external forces and causing its horizontal position to shift, ultimately affecting product quality.

[0035] A further improvement is that in the mold assembly, two side mold strips 2 are arranged opposite to each other, and negative pressure tubes 21 are arranged on the opposite surfaces of the two side mold strips 2 at intervals along their own length direction. The negative pressure tube 21 is used to seal the embedded sleeve 22. The embedded sleeve 22 is open at one end adjacent to the corresponding side mold strip 2 and closed at the other end. The inner cavity depth of the embedded sleeve 22 is greater than the length of the negative pressure tube 21.

[0036] In the present invention, the casting cavity is in the shape of a rectangular parallelepiped, and four side mold bars 2 are provided, two of which extend along the length direction of the casting cavity, and the other two extend along the width direction of the casting cavity. The two side mold bars 2 parallel to the length direction of the casting cavity are connected with negative pressure pipes 21, and the embedded sleeves 22 are connected through the outer sealing sleeve of the negative pressure pipe 21, so that after pouring the concrete slurry, the two sides of the solidified concrete slab 9 are fixedly connected with the embedded sleeves 22 spaced apart along the height direction of the concrete slab 9, forming a Fig.19 The product shown in the figure can be inserted into the embedded sleeve 22, and the outer diameter of the docking post is the same as the inner diameter of the embedded sleeve 22, and the length is greater than the length of the inner cavity of the embedded sleeve 22, and less than or equal to twice the length of the inner cavity of the embedded sleeve 22, so as to facilitate the insertion of the embedded sleeve 22. Fig.19 The products shown are precisely docked for easy assembly and splicing.

[0037] A further improvement is that the two side mold strips 2 extending along the length direction of the casting cavity are both hollow structures, and the negative pressure pipe 21 is connected to the vacuum pump 23 through the inner cavity of the side mold strip 2.

[0038] After adopting the above-mentioned improvements, during the process of pouring concrete slurry, the air in the inner cavity of the negative pressure tube 21 and the side mold strip 2 can be extracted through the vacuum pump 23, so that a vacuum is formed in the inner cavity of the negative pressure tube 21 and the side mold strip 2, and the embedded sleeve 22 is firmly adsorbed on the negative pressure tube 21 to prevent the embedded sleeve 22 from being affected by the flow of concrete slurry and shifting in position, which ultimately causes the concrete slurry to contact the negative pressure tube 21 and solidify, affecting the demoulding production of the side mold strip 2.

[0039] A further improvement is that the closed end of the embedded sleeve 22 is connected to a support bar 221, which is used to support the steel bar 8; the support bar 221 is a support groove extending in the horizontal direction; the support groove extends in a length direction parallel to the embedded sleeve 22, the separation and combination unit 3 corresponds one-to-one with the side mold bar 2, and the moving direction of the output end of the separation and combination unit 3 is a horizontal direction perpendicular to the length direction of the side mold bar 2.

[0040] After a groove-shaped support strip 221 is provided at the closed end of the embedded sleeve 22, the embedded sleeve 22 is sealed and connected to the negative pressure tube 21, and the radial position of the embedded sleeve 22 is adjusted so that the groove of the support strip 221 connected to the closed end of the embedded sleeve 22 faces upward, and the position of the embedded sleeve 22 is fixed by the vacuum pump 23, thereby fixing the position of the support strip 221, and then the steel bar 8 can be placed at the support adjustment 221, and the support strips 221 at the ends of the embedded sleeve 22 connected to the two opposite side mold strips 2 can respectively support the two ends of the steel bar 8, so that the steel bar 8 is suspended between the bottom and the mouth of the casting cavity, and after concrete slurry is injected into the casting cavity, the concrete slurry is solidified to form a concrete slab 9 and is fixedly connected to the steel bar 8, and the structural strength of the concrete slab 9 is increased by the steel bar 8.

[0041] Since the steel bar 8 is located inside the casting cavity during the above casting process, compared with other methods of penetrating the side wall of the mold, the casting cavity of the present invention ensures the integrity of the side wall and avoids the steel bar 8 penetrating the side wall of the mold to form a gap for concrete slurry to flow in, thereby facilitating the demoulding production of the mold assembly.

[0042] The closed end of the embedded sleeve 22 is integrally connected with a closed cover 222, and the support bar 221 is fixed to one end of the closed cover 222 away from the embedded sleeve 22, and the outer diameter of the closed cover 222 is larger than the outer diameter of the embedded sleeve 22. Through the above design, the closed cover 222 can be embedded in the concrete slab 9 formed by the solidification of the concrete slurry, and the connection between the embedded sleeve 22 and the concrete slab 9 is strengthened to prevent the embedded sleeve 22 from being separated from the concrete slab 9.

[0043] It should be noted that a steel mesh is usually used in wall panels, and the steel mesh is composed of transverse steel bars and longitudinal steel bars. The steel bars supported by the support bars in the present invention are mainly transverse steel bars 8, that is, the length direction of the transverse steel bars 8 is parallel to the width direction of the casting cavity. When the negative pressure pipe 21 extends along the length direction of the casting cavity, the support bars 221 at the ends of the embedded sleeve 22 sealed and connected to the outside of the negative pressure pipe 21 support the longitudinal steel bars accordingly. Of course, in the actual production process, after the split unit 3 adjusts the side mold strips 2 to the mold closing position, transverse steel bars 8 can also be placed on the two support bars 221, as in the present invention. Figure 8 As shown, after the transverse reinforcement 8 is placed on each support bar 221, the longitudinal reinforcement can be tied and fixed on the transverse reinforcement 8, which can also achieve the technical effect of the present invention.

[0044] The specific structure of the mold assembly is as follows Figure 8 and Fig. 9 As shown, a base 11 is fixed below the bottom template 1, and the base 11 is fixed above the ground. The projection of the bottom template 1 on the horizontal plane is located within the projection of the base 11 on the horizontal plane. The bottom template 1 is a rectangular plate, and the length and width directions are parallel to the length and width directions of the casting cavity respectively.

[0045] The four side mold strips 2 are all arranged on the base 11, and all include a molding strip 24 and a closing strip 25. The cross-section of the molding strip 24 is U-shaped, and its opening faces away from the casting cavity. The closing strip 25 is fixed to the inner side of the molding strip 24, and the closing strip 25 and the molding strip 24 enclose an inner cavity of the side mold strip 2; among the two side mold strips 2 with longer lengths, that is, the two side mold strips 2 extending along the length direction of the casting cavity, the molding strip 24 has a side facing away from the closing strip 25 and is integrally connected with six negative pressure tubes 21, and the negative pressure tubes 21 are evenly spaced along the length direction of the molding strip 24. Two vacuum pumps 23 are provided, corresponding one to one to the above-mentioned two side mold strips 2. The vacuum pump 23 is fixed on the base 11, and its input end is connected to the closing strip 25.

[0046] There are four splitting and combining units 3, which are connected to the four side mold strips 2 in a one-to-one correspondence. Specifically, the splitting and combining units 3 include a splitting and combining oil cylinder 31, a splitting and combining guide rod 32 and a splitting and combining guide sleeve 33, wherein the cylinder barrel of the splitting and combining oil cylinder 31 and the splitting and combining guide sleeve 33 are both fixed above the base 11, the piston rod of the splitting and combining oil cylinder 31 extends in a horizontal direction perpendicular to the length direction of the corresponding side mold strip 2, and is fixedly connected to the closing strip 25, the axial direction of the splitting and combining guide rod 32 is parallel to the axial direction of the piston rod, the splitting and combining guide rod 32 is fixedly connected to the closing strip 25, and is slidably matched with the splitting and combining guide sleeve 33.

[0047] The four separation and combination units 3 drive the four side mold strips 2 to move simultaneously. When the four separation and combination oil cylinders 31 push the four side mold strips 2 closer to each other until they are connected end to end in sequence, the four side mold strips 2 are located in the mold closing position; anyway, when the four separation and combination oil cylinders 31 pull the four side mold strips 2 back through the piston rods, the four side mold strips 2 are separated from each other, making it convenient for the cured concrete slab 9 to separate from the mold assembly. The sliding-fitting separation and combination guide rods 32 and separation and combination guide sleeves 33 can ensure the smooth movement of the side mold strips 2.

[0048] A further improvement is that the movable component 6 includes a fixed frame 61, a translation component 62 for driving the negative pressure adsorption component 5 to move horizontally, and a lifting component 63 for driving the negative pressure adsorption component 5 to move up and down. One of the translation component 62 and the lifting component 63 is arranged on the frame 61 and the output end is connected to the other drive; the plane where the top surface of the positioning frame 4 is located coincides with or is adjacent to the plane where the cavity mouth of the casting cavity is located.

[0049] In the present invention, the frame 61 is fixed on the base 11, the translation assembly 62 is arranged on the frame 61, the output end is connected to the lifting assembly 63, and the output end of the lifting assembly 63 is connected to the negative pressure adsorption assembly 5, and the distribution direction of the positioning frame 4 and the mold assembly is consistent with the translation direction of the output end of the translation assembly 62. In this way, through the mutual cooperation of the translation assembly 62 and the lifting assembly 63, the position of the negative pressure adsorption assembly 5 can be adjusted flexibly.

[0050] The plane where the top surface of the positioning frame 4 is located is close to the plane where the cavity opening of the casting cavity is located. This makes it possible for the lifting and lowering movement amplitude of the negative pressure adsorption component 5 driven by the lifting component 63 directly above the positioning frame 4 to be substantially consistent with the lifting and lowering movement amplitude of the negative pressure adsorption component 5 driven by the lifting component 63 directly above the casting cavity, so as to facilitate the firm adsorption of the decorative plate 7 in the positioning opening 41 of the positioning frame 4, and to precisely control the height position of the decorative plate 7 between the top surface and the bottom surface of the decorative plate 7 above and below the plane where the cavity opening of the casting cavity is located.

[0051] Among them, the specific structure of the frame 61 is as follows Fig.11 and Fig.12 As shown, the frame 61 includes two end frames 611 spaced apart along the width direction of the casting cavity, the end frames 611 are of an inverted U-shaped structure, both ends of which are fixed above the base 11, a vertically arranged positioning plate 612 is fixed below the inner top wall of the end frames 611, and a positioning electromagnet 613 is fixedly penetrated through the positioning plate 612; a cross beam 614 and a slide rail 615 extending along the distribution direction of the two end frames 611 are arranged between the two end frames 611, both ends of the cross beam 614 are fixedly connected to the two positioning plates 612, the slide rail 615 is fixed directly below the cross beam 614, the slide rail 615 is in the shape of a circular axis, and both ends are fixedly connected to the cross beam 614 through connecting blocks, and there are two slide rails 615 and two cross beams 614 distributed side by side along the length direction parallel to the casting cavity.

[0052] The translation assembly 62 includes a travel motor 621 disposed just above the gap between the two cross beams 614. The travel motor 621 has two coaxial output shafts, and the output shafts are fixedly connected to rollers 622 coaxially. The rollers 622 roll on the cross beam 614 one by one. A travel frame 623 is fixed just below the travel motor 621. The travel frame 623 is located between the two slide rails 615. Travel sleeves 624 are fixed on both sides of the travel frame 623. The travel sleeves 624 are slidably sleeved outside the slide rails 615 one by one. The inner side of the travel sleeve 624 is provided with a travel sleeve 624. An axially distributed rolling unit includes balls 6241 distributed in a circular array with the axis of the walking sleeve 624 as the center line. The balls 6241 roll with their own centers as the centers and protrude from the inner wall of the walking sleeve 624. The centers of the balls 6241 are located between the circumferential inner wall and the circumferential outer edge of the walking sleeve 624. The spherical surface of the balls 6241 fits with the circumferential outer edge of the circular shaft-shaped slide rail 615. The walking frame 623 and the adjacent surfaces of the two positioning plates 612 are fixedly connected with positioning guide disks 6231, which are iron disks with the same axis as the positioning electromagnet 613.

[0053] The lifting assembly 63 includes a lifting motor 631 fixed on the walking frame 623. The output shaft of the lifting motor 631 is arranged downward in the vertical direction and is coaxially connected with a screw 632. The screw 632 is threadedly connected with a screw sleeve 633. A horizontal lifting plate 635 is fixed to the bottom end of the screw sleeve 633. A lifting guide rod 634 extending in the vertical direction is arranged directly above the lifting plate 635. The lifting guide rod 634 is slidably penetrated on the walking frame 623. The negative pressure pump 52 is fixed on the lifting plate 635.

[0054] After adopting the above structure, after the lifting motor 631 is started, it drives the screw 632 to rotate and act on the screw sleeve 633. Under the sliding cooperation of the lifting guide rod 634 and the walking frame 623, the lifting plate 635 moves smoothly in the vertical direction, thereby adjusting the height position of the negative pressure adsorption assembly 5, so that the adsorption shell 51 is close to or away from the positioning frame 4 and the mold assembly.

[0055] When the horizontal position of the lifting plate 635 and the negative pressure adsorption component 5 needs to be adjusted, the travel motor 621 is started, driving the roller 622 to roll on the beam 614. At the same time, the ball 6241 in the travel sleeve 624 fits against the circumferential outer edge of the slide rail 615 to ensure that the travel motor 621 and the travel frame 623 move smoothly along the length direction of the slide rail 615 and reduce the friction during translation.

[0056] When the positioning guide disk 6231 at one end of the traveling frame 623 is close to the positioning electromagnet 613 at one end, the positioning electromagnet 613 is energized to generate magnetism, thereby firmly adsorbing the positioning guide disk 6231 to fix the horizontal position of the traveling motor 621 and the traveling frame 623 to prevent them from shifting and sliding. When the positioning guide disks 6231 at both ends of the traveling frame 623 are firmly adsorbed by the two positioning electromagnets 613, the lifting plate 635 is located directly above the mold assembly and directly above the positioning frame 4, respectively. At this time, the negative pressure adsorption component 5 is respectively facing the casting cavity of the mold assembly and the positioning frame 4, thereby ensuring that during the concrete slurry casting process, the decorative plate 7 can be accurately fixed at the cavity mouth position of the casting cavity to ensure product quality, and when the negative pressure adsorption component 5 adsorbs the decorative plate 7 on the positioning frame 4, each adsorption shell 51 can face the decorative plate 7 to ensure the adsorption and fixation quality and avoid position deviation in the horizontal direction.

[0057] When the position of the negative pressure adsorption component 5 needs to be adjusted again, the positioning electromagnet 613 is powered off to remove the attractive fixing force on the positioning guide disk 6231, so that the travel motor 621 can drive the roller 622 to roll on the beam 614, thereby realizing the translation of the lifting plate 635 and the negative pressure adsorption component 5.

[0058] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
