Description
Technical Field
[0001] The utility model relates to the technical field of production and preparation of flame retardant density boards, in particular to a flame retardant density board shaping device. Background Art
[0002] Flame-retardant density board is made of wood fiber or other plant fiber as raw materials, and is applied with urea-formaldehyde resin or other suitable adhesives. Flame-retardant density board has good physical and mechanical properties and processing properties, and can be made into boards of different thicknesses. Therefore, it is widely used in furniture manufacturing, construction, interior decoration, shipbuilding, automobile and other industries. After the flame-retardant density board is manufactured, there is a certain probability of deformation during storage due to thermal expansion and contraction, air humidity and other reasons. In order to improve its flatness and prevent deformation, it needs to be aligned and extruded by a shaping device during storage.
[0003] After searching, the applicant found that a Chinese patent disclosed "a flame retardant density board shaping device", and its publication (announcement) number is "CN220762989U". The patent mainly includes a shaping support base plate, a sliding slot is provided on the shaping support base plate, a first shaping support side plate is provided vertically upward on the left side of the shaping support base plate, and a second shaping support side plate is provided vertically upward on the rear side. The flame retardant density board shaping device of the utility model can quickly place the stacked density boards on the shaping support base plate and realize their alignment operation, which is convenient for extrusion shaping. However, the above In the prior art, during the extrusion alignment process, since the density boards are stacked, the weight of the upper board will exert pressure on the lower board. At the same time, when squeezed from the side, this uneven force mode easily causes stress concentration inside the board, resulting in uneven stress distribution inside the board. During subsequent use or processing, this internal stress may be released, causing deformation of the board, such as warping and bending. In addition, the density board is not heated during the extrusion process, which easily leads to the flame retardant being unable to combine well with the board to form a stable flame retardant structure. For this reason, we propose a flame retardant density board shaping device. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] Example 1:
[0024] Please see the attached Figure 1 - Attachment Figure 6 , a flame retardant density board shaping device, including a bottom fixing frame 1, a shaping mounting frame 2 is fixedly installed on the left end surface of the bottom fixing frame 1, and positioning grooves 8 are provided on the front and rear end surfaces of the bottom fixing frame 1, and the positioning grooves 8 are connected to the shaping support base plate 3 through a sliding long plate 9. The surface of the shaping support base plate 3 is provided with a limiting heating device 4, and the limiting heating device 4 includes a heating plate 401, and the front and rear sides of the heating plate 401 are connected to the clamping plate 402 through a telescopic spring 405, and the heating plate 401 is connected to the heating coil 403 through a groove 404. Two limiting holes 406 are provided on the left and right surfaces of the heating plate 401 and the shaping support base plate 3, and a positioning column is fixedly installed on the bottom of the heating plate 401 and directly below the limiting hole 406. The sliding long plate 9 is provided with two groups and is fixedly installed on the front and rear sides of the shaping support base plate 3. At the bottom, the sliding long plate 9 is slidably connected to the inside of the positioning groove 8, and the bottom ends of the front and rear sides of the shaped mounting frame 2 are provided with sliding grooves 11. The front and rear sides of the shaped support base plate 3 are slidably connected to the inside of the two sets of sliding grooves 11. The right side of the shaped support base plate 3 is fixedly installed with an armrest 10, and the front outer surface of the shaped mounting frame 2 is fixedly installed with a display controller 6. The four corners of the bottom of the bottom fixed frame 1 are fixedly installed with a supporting non-slip base 7. The heating plate 401 is arranged on the surface of the shaped support base plate 3, and the limiting hole 406 is adapted to the positioning column. One end of the telescopic spring 405 is fixedly connected to the heating plate 401, and the other end is fixedly connected to the clamping plate 402. The clamping plate 402 is slidably connected to the surface of the heating plate 401. The groove 404 is opened on the surface of the heating plate 401, and the heating coil 403 is fixedly installed on the inner bottom surface of the groove 404.
[0025] There is enough space for the heating coil 403 to accommodate itself in the groove 404. The depth and width of the groove 404 are a certain value larger than the diameter of the heating coil 403. When the density board is placed in the groove 404 and squeezed, it will not contact the heating coil 403 and cause damage to it. When current passes through the heating coil 403, electrical energy is converted into thermal energy, and the heating coil 403 dissipates heat to the surrounding environment, thereby heating the density board. Heating helps the reaction of the flame retardant. If not heated, the flame retardant will find it difficult to fully exert its flame retardant effect and will not be able to combine well with the board to form a stable flame retardant structure. Two sets of telescopic springs 405 are provided at the connection between the clamping plate 402 and the heating plate 401. The strong elasticity of the telescopic springs 405 enables the clamping plate 402 to firmly clamp the density board. The height of the heating plate 401 is lower than the height of the density board to avoid the density board being completely placed inside the heating plate 401 and being unable to be squeezed.
[0026] Specifically, first, the shaping support base plate 3 is moved to the outside of the shaping mounting frame 2 by pulling the armrest 10, and then the clamping plates 402 on both sides are pulled, and the telescopic springs 405 are stretched, and the density board to be shaped is placed on the surface of the heating plate 401. Then, the clamping plates 402 are released, and the telescopic springs 405 are reset to drive the clamping plates 402 to contact the density board to complete the clamping, and the positioning columns at the bottom of the heating plate 401 are aligned with the limiting holes 406 of the shaping support base plate 3. This cycle is repeated to stack multiple heating plates 401 together. The setting of the positioning columns and limiting holes 406 ensures that multiple heating plates 401 are in the same vertical line. After that, the shaping support base plate 3 is pushed into the shaping mounting frame 2, and the heating coil 403 and the extrusion device 5 are started to complete the extrusion shaping to avoid the density board position moving during the extrusion process and causing quality failure. The device is to place the density boards first and then stack them together to avoid uneven stress distribution inside the boards caused by extrusion alignment.
[0027] Example 2:
[0028] Please see the attached Figure 1 - Attachment Figure 3 And attached Figure 7 , and on the basis of Example 1, it is further obtained that an extrusion device 5 is provided at the upper end of the shaping mounting frame 2, the extrusion device 5 includes an extrusion cylinder 502, and the front and rear inner walls of the shaping support base plate 3 are provided with limiting grooves 501, and two groups of extrusion cylinders 502 are provided. One end of the two groups of extrusion cylinders 502 and the interior of the shaping mounting frame 2 are fixedly connected with an extrusion plate 503, and the front and rear surfaces of the extrusion plate 503 are fixedly connected to the limiting slider 504. The two groups of extrusion cylinders 502 are fixedly installed on the top outer surface of the shaping mounting frame 2, and the two groups of limiting sliders 504 are respectively slidably connected to the inside of the two groups of limiting grooves 501, and the display controller 6 is electrically connected to the extrusion cylinder 502 and the heating coil 403.
[0029] The cooperation between the two extrusion cylinders 502, the limiting slider 504 and the limiting groove 501 makes the extrusion plate 503 very stable when it descends. The cooperation between the positioning groove 8 and the sliding long plate 9 and the cooperation between the forming support base plate 3 and the slide groove 11 enables the forming support base plate 3 to move to the appropriate position.
[0030] Specifically, by setting limit grooves 501 on both sides of the shaping mounting frame 2, the extrusion cylinder 502 pushes the extrusion plate 503 downward to extrude, while the limit slider 504 moves in the limit groove 501, ensuring that the extrusion plate 503 will not be offset in position, and can be aligned with the density board on the heating plate 401, thereby improving the stability of the extrusion shaping. The display controller 6 can display and control the pressure, so that the shaping pressure is maintained within a reasonable range.
[0031] The working principle of the utility model is a flame retardant density board shaping device. First, the shaping support base plate 3 is moved to the outside of the shaping mounting frame 2 by pulling the handrail 10, and then the clamping plates 402 on both sides are pulled, and the telescopic spring 405 is stretched, and the density board to be shaped is placed on the surface of the heating plate 401, and then the clamping plate 402 is released, and the telescopic spring 405 is reset to drive the clamping plate 402 to contact the density board to complete the clamping, and the positioning column at the bottom of the heating plate 401 is aligned with the limiting hole 406 of the shaping support base plate 3. This cycle is repeated, and multiple heating plates 401 are stacked together, and the positioning column The setting of the limiting holes 406 ensures that multiple heating plates 401 are in the same vertical line. After that, the shaping support base plate 3 is pushed into the shaping mounting frame 2, the heating coil 403 and the extrusion device 5 are started, and the extrusion cylinder 502 pushes the extrusion plate 503 downward to extrude. At the same time, the limiting slider 504 moves in the limiting groove 501, ensuring that the extrusion plate 503 will not be offset in position and can be aligned with the density board on the heating plate 401. The shaping is completed by extrusion, and then the armrest 10 is pulled to move the shaping support base plate 3 out of the shaping mounting frame 2 and proceed to the next step. At this point, the whole process ends.
[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
