[0028] The utility model provides a spray box. Figure 1-Figure 6 A specific embodiment of a spray box provided by the utility model.
[0029] like Figure 1-Figure 4 The embodiment of the utility model provides a spray box 100, comprising a box body 1 and a spray assembly 2 arranged on the box body 1, the spray assembly 2 comprising an upper lip plate 21 and a lower lip plate 22, the upper lip plate 21 and the lower lip plate 22 define a slurry outlet, the upper lip plate 21 is hinged on the box body 1 and is connected with an angle adjustment mechanism 3 for adjusting its rotation angle, a damping telescopic mechanism 4 is provided at one end of the upper lip plate 21 close to the slurry outlet, one end of the damping telescopic mechanism 4 is connected to the upper lip plate 21, and the other end is connected to a crossbeam 212 located above the upper lip plate 21, the crossbeam 212 is connected to both longitudinal ends of the upper lip plate 21, and / or the crossbeam 212 is installed on the upper lip plate through a bracket 211, the mounting point of the bracket 211 on the upper lip plate 21 is located at the rear side of the slurry outlet in the transverse direction, a plurality of damping telescopic mechanisms 4 are provided, and are arranged in sequence and spaced apart along the length direction of the upper lip plate 21.
[0030] In the utility model, the angle adjustment mechanism 3 can adjust the opening size of the slurry outlet by adjusting the rotation angle of the upper lip plate 21, and then adjust the spraying flow rate to change the overall thickness of the slab to meet various sheet material production requirements. The damping telescopic mechanism 4 can adapt to the changes in the adaptive force on the upper lip plate 21 during the slurry spraying process, and play an anti-deformation role to ensure that the thickness of the slab formed by spraying is uniform and flat. It can be understood that in order to further improve the anti-deformation ability, the telescopic direction of the damping telescopic mechanism 4 is perpendicular to the upper surface of the upper lip plate 21.
[0031] In addition, it is worth mentioning that, in one embodiment, the box body 1 is a sealed box body, and the sealed box body 1 is connected to an air pressure regulating mechanism, which can regulate the pressure inside the box body 1, so as to achieve the function of stabilizing the pressure of the internal slurry.
[0032] It should be noted that the lower lip plate 22 can be integrally formed with the box body 1, or can be detachably connected to the box body 1 to facilitate maintenance and replacement.
[0033] Specifically, see Figure 4The damping telescopic mechanism 4 includes a damping telescopic rod 41 and a mounting seat 42. The mounting seat 42 is fixedly connected to the upper lip plate 21. One end of the damping telescopic mechanism 4 is connected to the cross beam 212, and the other end is hinged to the mounting seat 42. In this way, the damping telescopic rod 41 can adapt to the change of the force acting on the upper lip plate 21 to play an anti-deformation role, and the telescopic damper is hinged to the mounting seat 42, which can adjust the direction of the adaptive force when resisting deformation, thereby improving applicability.
[0034] Furthermore, the mounting seats 42 are adjacently arranged along the length direction of the upper lip plate 21 . The adjacent arrangement can expand the compensation area for the deformation of the upper lip plate 21 . The spacing distance between the mounting seats 42 can be 5 mm-20 mm.
[0035] Furthermore, a threaded section is provided at the upper end of the damping telescopic rod 41, and the threaded section passes through the cross beam 212 and is locked by a nut. In this way, the telescopic length of the damping telescopic rod 41 can be adjusted by rotating the nut, thereby adjusting the preload force to suit different production scenarios.
[0036] Specifically, the bracket includes a plurality of bracket plates sequentially arranged at intervals along the length direction of the upper lip plate. The bracket plates can not only be used to install the crossbeam 212 , but also improve the deformation resistance of the upper lip plate 21 .
[0037] Specifically, in order to prevent the slurry in the box body 1 from separating and settling, in one embodiment, a stirring assembly 5 is provided on the box body 1 for stirring the slurry in the box body 1, which can homogenize the slurry by stirring the slurry to prevent precipitation.
[0038] For further information, see Figure 6 In one embodiment, the stirring assembly 5 includes a stirring roller 51 rotatably installed in the box body 1, and the stirring roller 51 is defined to form a hollow cavity. The stirring roller 51 is also spaced apart and provided with a plurality of stirring holes 511 connected to the hollow cavity. By adopting a stirring roller 51 of this shape, turbulence generated when the slurry fluid enters and exits the opening can be utilized to promote the mixing of slurry raw materials, so that when the slurry has a certain initial speed, the internal fibers present three-dimensional multi-directional fiber interlacing. Compared with the two-dimensional directional interlacing produced by the existing wolf-tooth-shaped stirring roller 51, the stirring effect is better, which can improve the quality of the produced board.
[0039] Furthermore, the stirring roller 51 is provided with a plurality of stirring holes 511 groups at intervals along its axial direction, and the stirring holes 511 include a plurality of stirring holes 511 located in the same radial direction of the stirring roller 51. In this way, the stirring holes 511 can be more evenly distributed on the stirring roller 51, thereby improving the stirring effect.
[0040] The stirring roller 51 is connected to a driving mechanism 52 for driving the stirring roller 51 to rotate. The driving mechanism 52 includes but is not limited to a motor, a hydraulic cylinder, and a pneumatic cylinder.
[0041] Specifically, in one embodiment, both ends of the stirring roller 51 are rotatably installed in the housing 1 through bearings, and the stirring roller 51 is clearance-matched with each of the bearings. In this way, the requirement for the coaxiality of the stirring roller 51 and the driving mechanism 52 can be reduced, that is, the shaft end runout can be reduced, and then the wear at the shaft end fitting can be reduced, so as to achieve the effect of strengthening the seal and reducing leakage of slurry. In addition, the shaft end of the stirring roller 51 is sealed with pressurized circulating oil, and the fixed structure of the bearing adopts a pressure oil pipe circulating oil filling method. The front and rear of the bearing are sealed with sealing rings to isolate the slurry leaked from the shaft end and extend the service life of the bearing.
[0042] In order to observe the stirring of the liquid in the box body 1 without affecting the sealing performance of the box body 1 , in one embodiment, the box body 1 is provided with an observation component 7 for observing the interior of the box body 1 .
[0043] Specifically, the observation assembly 7 includes a transparent plate detachably provided on the box body 1. It is worth mentioning that the transparent plate is installed on the box body 1 through a quick-opening latch, so that the transparent plate can be opened and closed.
[0044] Specifically, the box body 1 is detachably connected to a pulp inlet bin 6 which is connected to the interior of the box body 1. In this way, different types of pulp inlet bins 6 can be replaced according to different scenarios. Moreover, it can be understood that the prepared pulp flows in through the feed port provided in the pulp inlet bin 6, and the pulp inlet bin 6 can play the role of temporary liquid storage to ensure that the pressure in the box body 1 is not affected by the outside world.
[0045] Furthermore, considering that some liquid in the pulp inlet bin 6 will still remain after entering the box body 1, in order to avoid disassembling the entire pulp inlet bin 6 to discharge the residue, in one embodiment, a slag discharge port 61 and a sealing structure detachably provided at the slag discharge port 61 are provided at the bottom of the pulp inlet bin 6, so that the slag discharge port 61 can be opened and closed by the sealing structure to achieve the functions of feeding and discharging slag.
[0046] Specifically, a lifting mechanism for adjusting the height of the box body 1 relative to the ground is further provided at the bottom of the box body 1, so that the distance between the pulp outlet and the conveyor belt can be further adjusted by the lifting mechanism, so that the scope of application is wider.
[0047] 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, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
