[0014] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0015] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0017] Please refer to Figures 1 to 3 The utility model provides a spiral feeding weighing material distribution machine, comprising a material distribution lifting platform 10, a conveyor belt machine 20 placed in the middle of the material distribution lifting platform 10 for receiving the pallet mold A, a mobile platform 30 movable along the length direction of the material distribution lifting platform 10, a weighing structure 40 installed on the mobile platform 40, a spiral feeder 50 installed on the weighing structure 40, a material distribution belt 60 installed on the mobile platform 40 and located on one side below the weighing structure 40, and a shovel installed on the material distribution lifting platform 10 for leveling the raw materials in the pallet mold A. The device 70 weighs the raw material through the weighing structure 40, weighs the raw material inside the spiral feeder 50, feeds it into the weighing structure 40, and feeds the raw material into the cloth belt 60, and transfers the raw material into the pallet mold A through the cloth belt 60. The cloth height is controlled by the cloth lifting platform 10, and the function of the moving platform 30 is to achieve the effect of moving the cloth, that is, without the need to move the pallet mold, the material can be evenly distributed in the pallet mold, which can effectively achieve a more uniform cloth effect.

[0018] It is worth noting that the screw feeder includes a hopper, a plurality of screws placed at the feeding port of the hopper, and a motor connected to each screw. Each screw is controlled by a separate motor frequency conversion. The position of each screw can be more accurately controlled to extrude materials, which is necessary for the production of certain plates. The old technology uses a belt to pull the material out from a gap under the hopper. It cannot control the amount of material at different positions and has low precision.

[0019] In this embodiment, the material lifting platform 10 includes two lifting beams 11 spaced apart and a screw lift 12 for lifting the two lifting beams 11. The conveyor belt 20 is located between the two lifting beams 11. The screw lift 12 is prior art and its structure is not described herein.

[0020] In this embodiment, the mobile platform 30 is installed on the two lifting beams 11 through a walking mechanism 31, and the walking mechanism 31 includes a rack 311 installed on the two lifting beams 11, a gear 312 installed on the mobile platform 30 and meshing with the rack 311, a walking motor 313 transmission connected to the gear 312, and a pulley 314 slidably installed on the lifting beam 11 and fixed to the mobile platform 30. In this embodiment, the walking motor 313 is transmission connected to the gear 312 through a chain to realize the function of driving the mobile platform 30 to walk on the two lifting beams 11 through the walking motor 313.

[0021] In this embodiment, the weighing structure 40 includes a mounting frame 41, a weighing belt 42 mounted on the mounting frame 41, and a force sensor 43 disposed between the mounting frame 41 and the mobile platform. There are four sensors 43, which are distributed at the four corners between the mounting frame 41 and the mobile platform. The force sensor weighs the total weight of the entire upper part, so after the screw feeder is loaded with materials, the amount of material discharged is controlled by subtraction weighing, that is, the value of the total weight reduction.

[0022] After the screw feeder feeds the raw materials into the weighing belt 42, the falling raw materials are weighed and measured by the measuring sensor 43. After the weighing measurement is completed, the raw materials are fed into the tray mold A through the weighing belt. Through the moving function of the moving platform, the head of the material tray mold A can be evenly distributed to its tail, and the distribution is more uniform.

[0023] The scraping device 70 includes a scraping frame 71 installed between the two lifting beams 11, a scraping plate 72 installed on the scraping frame 71 through a moving pair, and a cylinder 73 installed on the scraping frame 71 for driving the scraping plate 72 to rise and fall. The moving pair can be a guide pair or a structure in which a guide column and a slider cooperate, and its purpose is to ensure that the scraping plate 72 can be lifted and lowered on the scraping frame under the drive of the cylinder.

[0024] What the utility model aims to achieve is that after the raw materials are weighed, the raw materials can be distributed from the front end to the rear end of the pallet mold through the moving function of the moving table without moving the pallet mold, so as to achieve the effect of distributing the raw materials into the pallet mold more evenly, and the material protruding outside the pallet mold can be flattened by the shoveling device, thereby improving the degree of integration of the process machine and increasing work efficiency.

[0025] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
