Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0024] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0026] Please see Figures 1 to 4 The pulp layer pre-compression device according to one embodiment of the present invention includes a bearing component 10 and a pressing component 20 connected to the bearing component 10.

[0027] The supporting assembly 10 includes a base 11, a lower mold 12 installed in the middle of the top surface of the base 11, a heating element (not shown) installed inside the lower mold 12, a gantry frame 13 installed on the top surface of the base 11, and a temperature controller 14 installed on the gantry frame 13. The lower mold 12 is used to accommodate the pulp layer, and the temperature controller 14 is connected downwards to the heating element via a cable 15 to control the surface temperature of the lower mold 12, thereby controlling the dryness of the pulp layer during the pre-pressing process.

[0028] In this embodiment, as Figure 3 As shown, guide grooves 131 are provided on the opposite side walls of the gantry frame 13, and a through hole 132 is provided in the middle of the top of the gantry frame 13. The through hole 132 and the guide grooves 131 are used to match and connect the pressing assembly 20.

[0029] In this embodiment, the guide groove 131 is arranged in the vertical direction, and the two guide grooves 131 are located on opposite sides of the lower mold 12.

[0030] The pressing assembly 20 includes a bracket 21 connected to the middle of the top of the gantry 13, a pressing drive cylinder 22 mounted on the bracket 21, an adjusting frame 23 connected to the end of the pressing drive cylinder 22, a pressing head 24 mounted on the bottom of the adjusting frame 23, guide shafts 25 connected to opposite sides of the pressing head 24, and rollers 26 respectively mounted on opposite upper and lower sides of the guide shafts 25 away from the pressing head 24. The guide shafts 25 are used to pass through guide grooves 131, and the rollers 26 are used to abut against the inner surface of the side wall of the gantry 13 to achieve a sliding connection between the pressing head 24 and the gantry 13. The pressing head 24 is coaxially arranged with the lower die 12, and the pressing head 24 is used to match and embed into the lower die 12, so that the pulp layer is pre-pressed between the pressing head 24 and the lower die 12. During pre-pressing, the heat generated by the heating element is transferred to the lower mold 12, which can effectively dry the pulp layer, accurately control the drying rate of the pulp layer, and avoid quality problems such as product deformation and cracking, so as to meet the production needs of different products.

[0031] In this embodiment, the cylinder body of the downward drive cylinder 22 is fixedly installed on the top of the gantry frame 13, and the piston rod of the downward drive cylinder 22 passes through the through hole 132 and is connected downward to the adjustment frame 23.

[0032] In this embodiment, the adjusting frame 23 is a scissor-type hand-cranked lifting frame. The height of the adjusting frame 23 can be changed by hand-cranking, thereby adapting to pulp layers of different thicknesses and effectively improving the applicability of pre-pressing.

[0033] Furthermore, such as Figure 4 As shown, support rods 250 are connected to the upper and lower opposite sides of the end of the guide shaft 25 away from the pressure head 24. Rollers 26 are rotatably connected to the opposite sides of the end of each support rod 250 away from the guide shaft 25 to ensure the smoothness and stability of the relative sliding between the pressure head 24 and the gantry frame 13.

[0034] The aforementioned pulp layer pre-pressing equipment has a simple structure and is easy to use. The lower mold 12 is equipped with a heating element. During pre-pressing, the heat generated by the heating element is transferred to the lower mold 12, which can effectively dry the pulp layer, accurately control the drying rate of the pulp layer, and avoid quality problems such as product deformation and cracking, so as to meet the production needs of different products.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
