Description

Technical Field

[0001] The utility model relates to the technical field of forming machine equipment, in particular to a forming machine for a speaker paper cone. Background Art

[0002] Traditionally, a forming machine used for making speaker paper cones is generally composed of a pulp barrel and a robotic arm moving mechanism, a hot pressing forming mechanism and a dry material picking mechanism arranged thereon. The robotic arm moving mechanism is provided with a mold connected to a negative pressure adsorption device. The mold is immersed in the pulp barrel to take out the material through the robotic arm moving mechanism, and then the pulp is adsorbed on the mold through the negative pressure adsorption device. The robotic arm moving mechanism is then moved to the hot pressing forming mechanism for mold forming, and finally taken out by the dry material picking mechanism. At the same time, the mold is fixed to the robotic arm moving mechanism by bolts, and personnel can replace different molds according to actual use. However, when using the bolt fixing method, personnel need to use specific tools to disassemble and install when replacing, and the replacement is cumbersome and inconvenient.

[0003] The application number is CN202320380229.7, which discloses a forming machine for a speaker paper cone and relates to the technical field of speaker paper cone making equipment. The forming machine for a speaker paper cone comprises a machine body, a pulp barrel is provided on the machine body, a mechanical arm moving mechanism is provided on the pulp barrel, a mold is provided on the mechanical arm moving mechanism, an extension block is provided at one end of the mold, a through hole is provided on the extension block, the mechanical arm moving mechanism is connected to the extension block through a connecting component, the connecting component comprises a placement block connected to the mechanical arm moving mechanism and a positioning member arranged thereon, a card slot for inserting the extension block is provided on the placement block, an insertion rod which can be inserted into the through hole is slidably provided on the inner wall of the card slot, one end of the positioning member is connected to the insertion rod, and the positioning member is driven to push the insertion rod to move horizontally back and forth along the length direction of the placement block. Traditionally, a bolt fixing method is adopted, and personnel need to use specific tools to disassemble and install when replacing the mold. The replacement is relatively cumbersome and not convenient enough. The utility model can facilitate personnel to replace the mold.

[0004] The above document discloses a speaker cone forming machine with the following defects: when the forming machine is in operation, the molds are fixed by positioning parts. When the mold needs to be replaced, the structure is limited by structures such as plug rods and positioning parts, which makes it difficult to disassemble and assemble, reducing the practicality of the mold.

[0005] It can be seen from this that the existing paper cone forming machine does not have the function of more easily disassembling, assembling and replacing the mold, and it is necessary to improve the existing deficiencies and provide a function that can disassemble, assemble and replace the mold.
