[0020] The present invention cooperates with the pushing frames on the front and rear sides through the extrusion block, so that when the air-drying frame drives the sliding scraper and the fixed scraper to change from one side to the other side to scrape off the water film, the baffle on one side automatically switches to the closed mode and the baffle on the other side automatically switches to the open mode, thereby avoiding the problem of absorbing the water film that has just been scraped and sprayed as much as possible.

DETAILED DESCRIPTION

[0037] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.

[0038] Embodiment 1: A water film cooling and shaping device for stone plastic box board, combined with the attached Figure 1 To Attachment Figure 7, including an ultrasonic atomizer 1, a shaping frame 2 is fixedly connected to the top of the ultrasonic atomizer 1, the right side of the shaping frame 2 is supported on the ground, a high-pressure fan 3 is fixedly connected to the front side of the top of the ultrasonic atomizer 1, the high-pressure fan 3 is connected to the air duct 4, the tiny water droplets generated by the ultrasonic atomizer 1 are guided to the wind knife 5 by the high-pressure fan 3 through the air duct 4, the upper part of the shaping frame 2 is connected to three equally spaced wind knives 5 rotating from front to back, the upper part of the shaping frame 2 is fixedly connected to a guide frame 6 symmetrically distributed along the left and right sides of the shaping frame 2, the shaping frame 2 is slidably connected to an air drying frame 11 along the front and rear directions, and the front and rear sides of the air drying frame 11 are fixedly connected to the left and right sides of the shaping frame 2. The sliding plates 7 are symmetrically distributed, and the sliding plates 7 are slidably connected to the adjacent guide frames 6. The left and right opposite sliding plates 7 are rotatably connected with copper tubes 8 distributed at equal intervals from front to back, and the copper tubes 8 are in contact with the bottom of the stone plastic box board. The upper part of the shaping frame 2 is fixedly connected to the electric slide rails 9 symmetrically distributed along the left and right shaping frame 2. The electric slide rails 9 are slidably connected with sliders 10. The bottom of the slider 10 is fixedly connected to the air-drying frame 11 for driving the air-drying frame 11 to move in the front and rear directions. The upper part of the air-drying frame 11 is slidably connected with a sliding scraper 12 in the up and down directions, and the lower part of the air-drying frame 11 is fixedly connected with a fixed scraper 13. The fixed scraper 13 and the sliding scraper 12 are both set as triangular pyramids.

[0039] First, connect the pipe opening of the air drying rack 11 with the hose of the external vacuum heat absorption system, then put the stone plastic box board to be cooled and shaped between the copper tubes 8 on the rear side, and push the stone plastic box board from the back to the front, so that the stone plastic box board moves along the copper tube 8 rolling on the rear side, and passes between the sliding scraper 12 and the fixed scraper 13 until the front end of the stone plastic box board is pushed onto the copper tube 8 on the front side, then stop pushing the stone plastic box board, and start turning on the ultrasonic atomizer 1, the high-pressure fan 3 and the electric slide rail 9;

[0040] After starting up, the tiny water droplets generated by the ultrasonic atomizer 1 are guided to the wind knife 5 by the high-pressure fan 3 through the air duct 4, and then blown evenly to the surface of the stone plastic box board by the wind knife 5, forming a layer of fine water film. This layer of water film quickly takes away a large amount of heat from the surface of the stone plastic box board through the latent heat of evaporation, realizing rapid and uniform cooling, which is conducive to the rapid molding of the stone plastic box board;

[0041] The electric slide rail 9 drives the slider 10 to slide back and forth, thereby driving the air-drying rack 11 to move back and forth. The air-drying rack 11 drives the slide plate 7, the copper tube 8, the sliding scraper 12 and the fixed scraper 13 to move back and forth synchronously. In this way, the moving sliding scraper 12 and the fixed scraper 13 scrape the upper and lower surfaces of the stone plastic box board to the upper surface of the sliding scraper 12 and the lower surface of the fixed scraper 13 respectively. The vacuum heat absorption system acts on the scraped water film through the air-drying rack 11, and absorbs it together with the heat, thereby achieving a continuous cooling effect.

[0042] After the stone plastic box board completes the cooling and shaping of this part, continue to push the stone plastic box board forward to move the next part to the cooling and shaping area, and repeat this process until the cooling and shaping of the entire stone plastic box board is completed, and then the machine can be turned off.

[0043] In summary, the present invention forms a dynamic water film distribution through the synergistic effect of spraying water by the wind knife 5 and scraping off the water film by the sliding scraper 12 and the fixed scraper 13, which helps to continuously exchange heat, thereby accelerating the cooling process. It can also ensure that the water film is evenly distributed on the surface of the stone plastic box board to avoid local drying or water accumulation, which is beneficial to the overall temperature balance and prevents the stone plastic box board from being deformed due to uneven cooling.

[0044] In the above process, the copper tube 8 not only plays a boosting role in pushing the stone plastic box board, but also contacts with the lower surface of the stone plastic box board when moving back and forth with the air-drying rack 11, thereby conducting heat and cooling the stone plastic box board, further enhancing the effect of cooling and shaping the stone plastic box board. In addition, the sliding scraper 12 and the fixed scraper 13 can not only scrape off the heat-absorbing water film when moving back and forth, but also smooth the surface of the stone plastic box board to enhance the shaping effect.

[0045] Embodiment 2: Based on embodiment 1, Figure 1 and attached Figure 8 , and also includes three rotating blocks 14, which are fixedly connected to the right side of the corresponding wind knife 5, and a sliding frame 15 is slidably connected to the side of the shaping frame 2 close to the rotating block 14 along the front and rear direction, and the sliding frame 15 is movably connected to the rotating block 14, and the air-drying rack 11 can move forward and backward to contact the sliding frame 15, and the front and rear parts of the right side of the shaping frame 2 are fixedly connected with magnetic blocks 16 symmetrically distributed up and down, and the front and rear sides of the sliding frame 15 are fixedly connected with magnetic blocks 16 symmetrically distributed up and down, and the magnetic blocks 16 on the sliding frame 15 are magnetically matched with the adjacent magnetic blocks 16 on the shaping frame 2.

[0046] When the air drying rack 11 moves forward to contact the front side of the sliding frame 15, the air drying rack 11 pushes the sliding frame 15 to slide forward, thereby toggling the wind knife 5 to deflect backward through the rotating block 14, so that the outlet of the wind knife 5 faces the rear side. At this time, the adjacent magnetic blocks 16 on the front side are magnetically attracted to each other to fix the sliding frame 15, thereby fixing the wind knife 5 that has completed the reversal;

[0047] When the air-drying rack 11 moves backward until it contacts the rear side of the sliding frame 15, the air-drying rack 11 pushes the sliding frame 15 to slide backward, so that the magnetic blocks 16 that are attracted are separated from each other. At the same time, the sliding frame 15 moves the wind knife 5 forward through the rotating block 14, so that the outlet of the wind knife 5 faces the front side. At this time, the adjacent magnetic blocks 16 on the rear side are attracted to each other, and the sliding frame 15 is fixed again, thereby fixing the wind knife 5 that has completed the reversal.

[0048] In this way, intermittent reversing of the wind knife 5 is achieved, so that the blowing surface of the wind knife 5 can cover the surface of the stone plastic box board more evenly, avoiding the wind knife 5 being fixed downward, causing some areas to cool too fast or too slow, ensuring overall cooling uniformity, while reducing internal stress concentration and reducing the risk of deformation and cracking of the stone plastic box board.

[0049] Combined with Fig. 9 To Attachment Fig.10 , and also includes a pushing rack 17 symmetrically distributed along the front and back of the shaping rack 2. There are four pushing racks 17, which are fixedly connected to the upper and lower parts on the front and back sides of the shaping rack 2 respectively. The upper and lower sides of the air-drying rack 11 are rotatably connected with a rotating plate 18 symmetrically distributed along the front and back of the air-drying rack 11. A torsion spring 19 is fixedly connected between the rotating plate 18 and the air-drying rack 11. A pulling rack 20 symmetrically distributed along the left and right of the rotating plate 18 is fixedly connected in the middle of the rotating plate 18. The upper and lower sides of the air-drying rack 11 are slidably connected with extrusion blocks 21 symmetrically distributed along the left and right of the air-drying rack 11. The extrusion blocks 21 are set in a V-shape. The pulling rack 20 is extruded and matched with the adjacent extrusion blocks 21, and the extrusion blocks 21 move to contact the pushing rack 17.

[0050] In order to prevent the sliding scraper 12 and the fixed scraper 13 from absorbing the water film that has just been scraped and sprayed on the other side when moving toward one side to scrape off the water film that has absorbed heat, the air drying rack 11 needs to be shielded to a certain extent by a baffle, and the specific operation is as follows:

[0051] Initially, the air-drying rack 11 is in the middle position, and the rotating plate 18 is in an inclined state. Before preparing to scrape the film, the air-drying rack 11 is first controlled to move to the front side, and the air-drying rack 11 drives the rotating plate 18, the torsion spring 19, the pulling frame 20 and the squeezing block 21 thereon to move forward together, so that the front side of the squeezing block 21 contacts the front pushing frame 17, and the squeezing block 21 is squeezed by the front pushing frame 17, and moves backward, thereby squeezing the front pulling frame 20 to swing upward, and then drives the rotating plate 18 on the front side to swing downward, and the torsion spring 19 on the front side is deformed. In this way, when the air-drying rack 11 drives the sliding scraper 12 and the fixed scraper 13 to scrape the water film from front to back, the water film on the rear side of the air-drying rack 11 is mainly dried, and due to the shielding effect of the front rotating plate 18, the water film that has just been scraped and sprayed on the front side of the air-drying rack 11 can be avoided as much as possible.

[0052] Similarly, when the air-drying rack 11 drives the rotating plate 18, torsion spring 19, pulling frame 20 and extrusion block 21 thereon to move backward together, the rear side surface of the extrusion block 21 will contact the rear push frame 17, and under the extrusion effect of the rear push frame 17, the extrusion block 21 moves forward, thereby squeezing the rear pulling frame 20 to swing upward, causing the rear rotating plate 18 to swing downward. At this time, the squeezing block 21 no longer squeezes the front pulling frame 20, and the front rotating plate 18 swings upward under the reset effect of the front torsion spring 19. In this way, when the air-drying rack 11 drives the sliding scraper 12 and the fixed scraper 13 to scrape the water film from the back to the front, the water film on the front side of the air-drying rack 11 is mainly dried, and due to the shielding effect of the rear rotating plate 18, the water film that has just been scraped and sprayed on the rear side of the air-drying rack 11 can be avoided as much as possible.

[0053] In summary, the present invention cooperates with the push racks 17 on the front and rear sides through the extrusion block 21, so that when the air-drying rack 11 drives the sliding scraper 12 and the fixed scraper 13 to change from one side to the other side to scrape off the water film, the baffle on one side automatically switches to the closed mode, and the baffle on the other side automatically switches to the open mode, thereby avoiding the problem of absorbing the water film that has just been scraped and sprayed as much as possible.

[0054] Embodiment 3: Based on Embodiment 2, Fig.11 To Attachment Fig.13 , also includes a slide 22, the slide 22 is slidably connected to the rear side of the shaping frame 2, the bottom of the slide 22 is set as a curved surface, the front side of the slide 22 is in contact with the sliding scraper 12, and the slide 22 can lift the sliding scraper 12 upward when it slides upward, the upper part of the sliding scraper 12 is fixedly connected to an electromagnetic frame 23 symmetrically distributed along the sliding scraper 12, and the lower part of the sliding scraper 12 is slidably connected to a card frame 25 symmetrically distributed along the sliding scraper 12, which is used to fix the sliding scraper 12 on the shaping frame 2, and the card frame 25 is fixedly connected to a side close to the electromagnetic frame 23 with a magnetic strip 24, and the magnetic strip 24 cooperates with the adjacent electromagnetic frame 23 through repulsive magnetic forces, and a spring 26 symmetrically distributed along the front and back of the magnetic strip 24 is fixedly connected between the card frame 25 and the sliding scraper 12, and the air-drying frame 11 is provided with a card slot 27 symmetrically distributed along the left and right of the air-drying frame 11, and the card slot 27 is limitedly matched with the adjacent card frame 25.

[0055] Since the edge of the sliding scraper 12 is set in a ridge, the sliding scraper 12 cannot be directly squeezed upward through the stone plastic box board, so the distance between the sliding scraper 12 and the fixed scraper 13 cannot be automatically adjusted according to the stone plastic box board. Therefore, through the slide 22 with a curved bottom, the stone plastic box board that needs to be shaped can be squeezed by the slide 22 according to its own thickness to slide upward, and the slide 22 pushes the sliding scraper 12 to move upward. The sliding scraper 12 drives the electromagnetic frame 23, the magnetic strip 24, the bracket 25 and the spring 26 to move up and down together, so that the distance between the sliding scraper 12 and the fixed scraper 13 can be automatically adjusted according to the stone plastic box board, so that the sliding scraper 12 and the fixed scraper 13 can adapt to the stone plastic box boards of various thicknesses and improve the film scraping effect;

[0056] When the machine is turned on, the electromagnetic frame 23 is energized, and the magnetic strip 24 is pushed by the repulsive force, so that the magnetic strip 24 drives the card frame 25 to slide to the side close to the card slot 27, and the spring 26 is deformed until the card frame 25 is stuck in the card slot 27. In this way, the card slot 27 limits the card frame 25, so that the sliding scraper 12 is fixed on the air-drying frame 11, and the sliding scraper 12 is prevented from shaking up and down at will when scraping off the water film;

[0057] When shutting down, the electromagnetic frame 23 is powered off, the magnetic strip 24 loses its repulsive force, and the spring 26 is reset to drive the card frame 25 to slide to the side away from the card slot 27. In this way, the fixation of the sliding scraper 12 is released, so that when the stone plastic box plate is removed, the slide 22 slides downward and resets under the action of gravity, and the sliding scraper 12 also slides downward and resets under the action of gravity.

[0058] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
