Detailed implementation mode

[0022] The following will describe the technical solutions in the present invention in combination with the accompanying drawings in the present invention.

[0023] It should be noted that: Similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present invention, terms such as "first" and "second" are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0024] Please refer to Figures 1 to 4 , the present invention provides a particle forming device in a biomass straw granulator. In the prior art, if different shapes and sizes of formed particles are required, different equipment is needed for pressing and forming, which makes the cost of purchasing different equipment by enterprises relatively high and the versatility of basic equipment relatively low. To solve the above technical problems, the present invention optimizes the structure of the particle forming device to meet the needs of more shapes and sizes of particles and reduce the equipment purchase cost.

[0025] As shown in the figure, it mainly includes a die set 100, a top pressing set 200 arranged above the die set 100, and a bottom plate 300 arranged below the die set 100.

[0026] Now, the structure of the die set 100 will be described in detail:

[0027] The die set 100 includes a die supporting table 110 and a carrier plate 120. The die supporting table 110 is a thick table plate, and a number of die cavities 111 are opened in the die supporting table 110. As shown in the figure, the number of die cavities 111 are arranged at equal intervals. The die cavity 111 includes a hollow conical cavity 1111, and a hollow cavity 1112 is penetrated through the bottom of the hollow conical cavity 1111. The top and bottom of the die cavity 111 are penetrated and communicated.

[0028] The carrier plate 120 is a whole plate, and a die cup 121 is arranged on the carrier plate 120. The die cup 121 is a conical cup body 1212, and a hollow die hole column 1211 is opened in the middle of the die cup 121. As shown in the figure, the bottom of the hollow die hole column 1211 extends outward, and the extended section does not exceed the hollow cavity 1112.

[0029] The hollow shape of the hollow die hole column 1211 is the shape after final pressing and forming, which can be circular, square or other conventional shapes, and the specific shape can be selected according to user needs.

[0030] During use, the die cup 121 of the carrier template 120 is inserted into the die slot 111 of the die supporting table 110. Since the die slot 111 is conical and has a parallel end at the bottom, the die cup 121 will not move downward excessively and is placed within the die slot 111. The hollow die hole column 1211 in the middle of the die cup 121 will pass through the die slot 111 and be placed within the hollow slot 1112 to complete the matching installation. The shapes of the hollow die hole columns 1211 are various. When different shaped formed particles are needed, the carrier template 120 can be replaced correspondingly, thus meeting the requirements.

[0031] In order to meet different forming size requirements, the spatial size of the hollow slot 1112 is set to be larger than the outer diameter of the hollow die hole column 1211. Since the difference in forming sizes is not particularly large, for example, the diameter of circular particles is 2 - 10 cm. In this case, different sizes can all meet the requirement of placing the hollow die hole column 1211 within the hollow slot 1112. By setting the die supporting table 110 and the carrier template 120, different sizes and shapes can be replaced by replacing the carrier template 120, thereby achieving production for different requirements. This replacement design is ingenious, with a simple structure and easy operation.

[0032] In order to better install the carrier template 120, a surrounding plate 130 is also provided around the die supporting table 110. As shown in the figure, the height of the surrounding plate 130 is higher than that of the die supporting table 110. After the carrier template 120 is installed on the die supporting table 110, the top surface of the carrier template 120 is flush with the top surface of the surrounding plate 130.

[0033] The present utility model also provides a top pressing group 200, which includes a top plate 210, and a top column 230 is provided at the bottom of the top plate 210. A pressing template 231 is provided at the bottom of the top column 230, and the shape of the pressing template 231 is the same as that of the hollow die hole column 1211. When different shaped and sized hollow die hole columns 1211 need to be replaced, the pressing template 231 also needs to be replaced, so as to achieve one-to-one pressing and forming. The top pressing group 200 also includes a hydraulic cylinder for driving the top plate 210 to press downward.

[0034] The device further includes a bottom plate 300 which is arranged at the bottom of the mold supporting table 110. During the pressing and forming process, the bottom plate 300 is closely attached to the bottom of the mold supporting table 110. In addition, a lifting frame 310 is arranged at the bottom of the bottom plate 300, and the lifting frame 310 is hydraulically driven to lift and lower. As shown in the figure, the width of the bottom plate 300 is wider than that of the bearing table, and a push plate 320 and a driving cylinder are arranged at the end of the bottom plate 300. After the pressing and forming, the lifting frame 310 is driven downward to move the bottom plate 300 downward, which can drive the hydraulic cylinder of the top pressing group 200 to press again to eject the formed particles. Subsequently, under the action of the driving cylinder, the push plate 320 is pushed out to push out the formed particles, and then the lifting frame 310 is extended to abut against the bottom of the mold supporting table 110.

[0035] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
