Description

Technical Field

[0001] This utility model belongs to the field of screw technology, specifically relating to a detachable segmented screw. Background Technology

[0002] A screw is a cylinder with helical grooves cut on its outer surface or a cone with conical helical grooves cut on its outer surface. It is the core component of plastic molding equipment (such as extruders and injection molding machines), responsible for melting, plasticizing and conveying plastic forward. Its structure is simple and suitable for high-volume production, but its blending ability is weak. It mainly relies on the rotation of the screw to push the material. Two screws can rotate in the same direction or opposite directions to force the material to be conveyed. The blending effect is better than that of a single screw. It is especially suitable for modified materials with added powder / oil. With the development of industry, screws have also become an indispensable working tool.

[0003] However, the screws currently available on the market are not very convenient to use. They cannot be disassembled in sections, thus keeping the screw at a fixed length. This increases the difficulty of transporting the screw, the manpower required for moving it, and the cost of transporting it. It also hinders the screw from quickly reaching the working position, thereby increasing the overall working time and affecting the efficiency of subsequent work. Utility Model Content

[0006] An inner spring is fixedly connected inside the inner frame. One end of the inner spring is fixedly connected to a movable arc block. A locking plate is movably connected to the bottom of the movable arc block. A top screw is fixedly connected to the bottom of the locking plate. This makes the screw more convenient to use and allows it to be segmented and detachable. This means the overall length of the screw does not have to be fixed, reducing the difficulty of transporting the screw, the manpower required for moving the screw, and the cost of transporting the screw. It also helps the screw reach the working position quickly, thereby reducing the overall working time and accelerating the efficiency of subsequent work.

[0009] The utility model further illustrates that one side of bottom straight rod is fixedly connected with one side of hinge, one side of hinge is fixedly connected with one side of top straight rod, and the length of top straight rod is greater than the length of bottom straight rod, which can keep bottom screw rod and top screw rod in the same line, makes the splicing and disassembly of screw rod more smooth, improves the stability of work after splicing of screw rod, and is beneficial to long-time work of screw rod.

[0010] The utility model further illustrates that one side of movable arc block is movably connected with one side of inner small frame through inner spring, and the sum of the length of inner small frame and movable arc block is greater than the width of top straight rod, which can change the position state of movable arc block, provide the effect of clamping for components when inner spring pops out movable arc block, and enter inner small frame to cancel contact with external components when clamping is not needed.

[0011] The utility model further illustrates that one side of movable arc block is movably connected with one side of clamping plate, and the number of movable arc block and clamping plate is two, which improves the clamping effect after installation and improves the working stability of the whole screw rod.

[0012] The utility model further illustrates that the bottom of bottom screw rod is movably connected with the bottom of top screw rod, and the length and diameter of bottom screw rod and the length and diameter of top screw rod are equal, which is convenient for unified movement or splicing of screw rod.
