They are usually equipped with tenons and mortise grooves on both sides to facilitate docking during installation. Lightweight wall panels are not only light in weight, but also have the advantages of high strength, multiple environmental protection, thermal insulation, sound insulation, fire prevention, and rapid construction.

[0004] However, the above-mentioned disclosed scheme has the following shortcomings: the paint spraying device required for the mold in the prior art only has a spraying function and is unable to clean the residues in the mold, resulting in the paint being stained on the inner side of the mold after spraying, thereby affecting the next extrusion processing of the lightweight wall panel. Summary of the invention

[0011] Furthermore, an avoidance groove is provided on the reciprocating frame corresponding to the threaded sliding block.

[0012] Furthermore, one end of the reciprocating frame is in sliding contact with the upper surface of the suspended plate.

The present invention facilitates the movement of the device by means of a lifting support rod and a universal wheel, so that different positions in the mold can be switched to be cleaned and sprayed with a release agent. The reciprocating drive unit drives the reciprocating frame to reciprocate, thereby driving the gear and the spray pipe to rotate reciprocatingly, so that the atomizing nozzle can spray the release agent reciprocatingly.

At the same time, after stopping spraying the release agent, the residual release agent on the atomizing nozzle 11 is dried under high-speed reciprocating swing, so that the release agent will not solidify or fail due to long-term exposure to the air and affect the normal spraying of the atomizing nozzle 11, so that the efficiency of spraying the release agent is increased, and at the same time, half of the cavity of the mold can be sprayed. When spraying the other half of the cavity, it is only necessary to move the device a short distance to spray and apply; after extruding and forming the lightweight wallboard, the device is moved so that the cleaning unit cleans the remaining residue from the mold, and then sprays the release agent again, so that the cleaning efficiency is high, the spraying efficiency is high, and the high-quality molded lightweight wallboard is guaranteed, which solves the problem that the existing spraying device cannot clean the residue and affects the next molding of the lightweight wallboard.

[0027] The cleaning unit includes a threaded shaft 14; a plurality of the threaded shafts 14 are rotatably connected to the suspended plate 3; a synchronous driving unit is fixedly connected to the end of the threaded shaft 14; a threaded slider 24 is threadedly sleeved on the threaded shaft 14; a slot 13 is provided on the suspended plate 3 corresponding to the threaded slider 24; a movable baffle 21 is connected to the symmetrical axis on the lower end surface of the threaded slider 24; a movable brush 22 is connected to the side axis of the movable baffle 21; a fixed brush 23 is fixedly connected to the lower surface of the movable baffle 21; when working, the threaded shaft 14 is driven forward and reversely by the synchronous driving unit The movable baffle 21, the movable brush 22 and the fixed brush 23 are moved to contact and clean the two sides of the mold, so that the residue in the mold is swept out from one end. At the same time, the symmetrical movable baffle 21 is elastically centered, so that molds of different widths can be adapted by rotation, so that the adaptability is wider and one machine can be used for multiple purposes. At the same time, the cleaning efficiency is high, and half of the cavity of the mold can be cleaned at a time, and the cleaning can be completed in two times, which solves the problem of low cleaning efficiency of the existing cleaning device.

[0028] The synchronous drive unit includes a driven synchronous wheel 15; the driven synchronous wheel 15 is sleeved on the end of the threaded shaft 14; a synchronous belt 16 is sleeved on the driven synchronous wheel 15; the corresponding synchronous belt 16 on the suspended plate 3 is fixedly connected to a limit tube 17; the end of the synchronous belt 16 is meshingly connected to a driving synchronous wheel 18; a driving motor 19 is fixedly connected to the inside of the driving synchronous wheel 18; the driving motor 19 is fixedly connected to the side of the suspended plate 3; when working, the driving synchronous wheel 18 is driven to rotate by energizing the driving motor 19, and the driving synchronous wheel 18 drives the synchronous belt 16 and multiple driven synchronous wheels 15 to rotate. Rotation drives multiple threaded shafts 14 to reciprocate, thereby driving the threaded slider 24 and movable baffle 21, movable brush 22 and fixed brush 23 threadedly connected to the threaded shaft 14 to reciprocate, so that the movable brush 22 and fixed brush 23 are used to reciprocate and clean the remaining residue in the mold, so that when the release agent is sprayed, it is more comprehensive, and no residue remains to affect the next filling of raw materials for extrusion molding, so that the molding of the lightweight wallboard is always in a state without surface defects, so that the molding quality is high, and the cleaning efficiency of the mold is also higher, which solves the problem of low cleaning efficiency of the existing cleaning device.

[0029] The reciprocating drive unit includes a linkage plate 4 attached to the inner side of the suspended plate 3; a plurality of elastic members 5 are fixedly connected to the linkage plate 4; the end of the elastic member 5 elastically contacts with a synchronization plate 6; the synchronization plate 6 is fixedly connected to one end of the reciprocating frame 7; a cam 27 is attached to the synchronization plate 6; a reciprocating motor 26 is fixedly connected to the cam 27; the reciprocating motor 26 is fixedly connected to the upper surface of the suspended plate 3; when working, the cam 27 is driven to rotate by the reciprocating motor 26 being powered on, and the cam 27 squeezes the synchronization plate 6 and the reciprocating frame 7 to push, and then squeezes the elastic member 5 to deform, and then after the cam 27 rotates to the other direction, under the recovery deformation of the squeezed elastic member 5, the synchronization plate 6 and the reciprocating frame 7 are pushed to reset, Thereby, driven by the cam 27, multiple reciprocating frames 7 can reciprocate, thereby driving the high-speed reciprocating motion of the injection pipe 10, so as to realize large-area spraying of the release agent on both sides of the lightweight wall panel mold. After the spraying is completed, the high-speed reciprocating motion is continued for a period of time to shake off the residual release agent on the atomizing nozzle 11, so that the atomizing nozzle 11 can be kept dry and will not solidify and fail due to long-term exposure to the air, thereby greatly extending the service life of the atomizing nozzle 11. At the same time, the injection area of ​​a single atomizing nozzle 11 is made larger, making the spraying of the release agent more efficient, thereby solving the problem of low injection efficiency of a single nozzle due to the use of the atomizing nozzle 11 in the existing injection device.

[0030] An avoidance groove 20 is provided on the reciprocating frame 7 corresponding to the threaded slider 24; when working, the length of the avoidance groove 20 is much larger than the width of the threaded slider 24, so that when the reciprocating frame 7 reciprocates, it will not interfere with the reciprocating motion of the threaded slider 24, so that the two can run simultaneously, solving the problem that the existing spray cleaning device cannot run synchronously.

[0031] One end of the reciprocating frame 7 is in sliding contact with the upper surface of the suspended plate 3; when working, the reciprocating frame 7 can reciprocate horizontally through the sliding contact between one end of the reciprocating frame 7 and the upper surface of the suspended plate 3, so that it can stably mesh with multiple gears 9 to solve the problem of low synchronization of reciprocating motion in existing belt drives.

[0032] The spacing between the injection pipes 10 is the same as the spacing between the threaded sliders 24; during operation, the spacing between the injection pipes 10 is the same as the spacing between the threaded sliders 24, so that the mold of the lightweight wall panel can be cleaned of residual materials and sprayed with release agent at intervals, so that a mold of multiple containers can be cleaned and sprayed efficiently at one time, solving the problem that the existing cleaning and spraying devices cannot clean or spray a large number of molds at the same time.

[0033] By adopting the above scheme, when the present invention is in use, the lifting support rod 1 cooperates with the universal wheel 2 to make the device easy to move, so that different positions in the mold can be switched to clean and spray the release agent. The reciprocating drive unit drives the reciprocating frame 7 to reciprocate, thereby driving the gear 9 and the spray pipe 10 to rotate reciprocatingly, so that the atomizing nozzle 11 can reciprocate to spray the release agent. At the same time, after stopping the spraying of the release agent, the release agent remaining on the atomizing nozzle 11 is spun off under high-speed reciprocating swing, so that demolding will not be caused by long-term exposure to the air. The solidification or failure of the agent affects the normal spraying of the atomizing nozzle 11, so that the efficiency of spraying the demoulding agent is increased, and half of the cavity of the mold can be sprayed at the same time. When spraying the other half of the cavity, the device needs to be moved a short distance to spray and apply; after the lightweight wall panels are extruded, the device is moved to allow the cleaning unit to clean the remaining residues from the mold, and then the demoulding agent is sprayed again, so that the cleaning efficiency is high, the spraying efficiency is high and the high-quality molded lightweight wall panels are guaranteed, which solves the problem that the existing spraying device cannot clean the residues and affects the next molding of lightweight wall panels.
