[0001] This utility model belongs to the field of hot press technology, specifically a hot press for forming propeller carbon fiber. Background Technology

[0002] Hot presses are industrial equipment that use heating and pressure to shape, join, or solidify materials. They are mainly based on pulse heating technology or electromagnetic heaters, with temperature sensors to achieve precise temperature control. The material is heated to a molten state, and pressure is applied to promote intermolecular bonding, ultimately completing the shaping or welding process. In electronics manufacturing, they are used for the mechanical and electronic connection between ITO and ACF / FPC during LCD panel assembly. In the wood processing field, they are used to press wood blanks into plywood through high temperature and high pressure.

[0003] A search revealed that Chinese patent application number 202221284247.7 discloses a hot press for forming carbon fiber for propellers. This patent utilizes the shapes of the upper and lower mold cavities to effectively form carbon fiber into a propeller hub shape during hot pressing. The presence of a shaping rod allows the propeller hub-shaped carbon fiber to be wrapped around the outside of the shaping rod, which not only facilitates the subsequent removal of the carbon fiber but also improves efficiency and coating effect when wrapping the carbon fiber onto the propeller later.

[0004] However, the aforementioned hot press is only suitable for a single propeller, has a limited scope of application, and the mold cavity of the module is not easy to replace. Summary of the Invention

[0005] The purpose of this invention is to provide a hot press for forming propeller carbon fiber. By switching the mold cavity through a rotating module, the applicable range of the hot press is expanded and the working efficiency of the hot press is improved.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a hot press for forming propeller carbon fiber is provided, including a housing. A first connecting plate and a second connecting plate are fixedly connected to the inner sides of the top and bottom of the housing, respectively. A drive shaft and a lower rotating shaft are respectively connected through the middle part of the housing. Two drive wheels and driven wheels are respectively fixedly sleeved at the outer ends of the lower rotating shaft and the drive shaft. A transmission belt is frictionally sleeved on the outer sides of the drive wheels and driven wheels on the same side. A belt expander is frictionally contacted on the inner side of the transmission belt. A fixing frame is fixedly connected to the outer side of the belt expander. A motor body is fixedly connected to the outer end of the drive wheel. An upper module and a lower module are respectively fixedly connected to the middle parts of the drive shaft and the lower rotating shaft.

[0010] Optionally, the first telescopic cylinder pushes the upper pressure plate to the top surface of the upper mold cavity and then stops moving, and the second telescopic cylinder pushes the traction spring to rise until the upper mold cavity and the lower mold cavity are in close contact and then stops moving, so that the transmission belt will not contact the inner side of the fixed frame.

[0011] Optionally, a fixing frame is fixedly connected to each of the two outer sides of the housing, and a shaping rod is connected through the middle of the fixing frame.

[0012] Optionally, a reinforcing member is fixedly connected to the top of the motor body, and a housing is fixedly connected to the side of the reinforcing member.

By setting up an upper module and a lower module, two upper and lower mold cavities are connected respectively. Rotating the module allows for easy switching between different mold cavity combinations, suitable for the production needs of propellers of different shapes and sizes. The use of a first telescopic cylinder and a second telescopic cylinder to push the upper and lower pressing plates for pressing makes the pressing process more stable and precise, thereby improving production efficiency. The inclusion of a transmission belt and motor body ensures continuous operation of this utility model, reducing downtime and further improving work efficiency.

[0024] Furthermore, the lower rotating shaft 7 is connected to the left moving plate 15 and the right moving plate 16 through the ends on both sides of the outer casing 1, and rectangular holes are opened on both sides of the outer casing 1 to slide the left moving plate 15 and the right moving plate 16.

[0025] Furthermore, the bottom ends of the left moving plate 15 and the right moving plate 16 are respectively fixedly connected with a traction spring 17 and a fixing post 18, with the traction spring 17 located in the middle of the rectangular hole and the fixing post 18 located at the bottom of the rectangular hole.

[0030] Furthermore, the left moving plate 15 and the right moving plate 16 slide up and down along both sides of the outer casing 1, and the transmission belt 23 is located in the middle of the fixed frame 3.

[0031] Working principle: The drive shaft 12 and the lower rotating shaft 7 are connected through the middle of the outer casing 1. The drive shaft 12 drives the rotation of the lower rotating shaft 7. The outer ends of the drive shaft 12 are fixedly sleeved with the drive wheel 11 and the driven wheel 19 respectively.
