Description

Technical Field

[0001] The present application relates to the field of carbon fiber production devices, and more particularly, to a transmission device for carbon fiber. Background Art

[0002] During the carbon fiber production process, a transmission device for carbon fiber is provided between each section to transmit the carbon fiber. Through the stretching of the carbon fiber between two transmission devices, the carbon fiber transmitted in the section has the required tension. The stretching ratio between the two transmission devices directly affects various important properties of the carbon fiber. Therefore, during operation, the driving member of the transmission device needs to bear the load formed by hundreds of carbon fiber tows, and also needs to bear the load formed by the stretching between the two transmission devices.

[0003] Currently, the driving member in the carbon fiber transmission device needs to drive multiple transmission rollers to rotate for transmitting the carbon fiber. Then the driving member has to bear the reverse force during the meshing rotation between the gears, the load formed by the self-weight of multiple transmission rollers, the load formed by hundreds of carbon fiber tows, and the load formed by the stretching between the two transmission devices. However, the load borne by the driving member in the current carbon fiber transmission device is uneven, and currently, the intermediate gear is directly connected to one side bracket through a bearing housing, and its bearing capacity is small. In the case of excessive load, the driving member is extremely prone to damage. Once the driving stops rotating, all the carbon fiber tows that are running will be damaged and become waste filaments, resulting in huge waste during the repair process.

[0035] Embodiment

[0036] In the existing driving member in the carbon fiber transmission device, it is necessary to drive multiple transmission rollers to rotate to transmit the carbon fiber. Then the driving member has to bear the reverse force when the gears mesh and rotate, has to bear the load formed by the self-weight of multiple transmission rollers, has to bear the load formed by hundreds of carbon fiber tows, and has to bear the load formed by the draft between two transmission devices. However, currently, the load borne by the driving member in the carbon fiber transmission device is uneven, and currently the intermediate gear is directly connected to one side bracket through a bearing housing, and its bearing capacity is small. In the case of excessive load, the driving member is extremely prone to damage.

[0037] The present application aims to improve the technical problem that the driving member in the existing carbon fiber transmission device bears an excessive and uneven load and is prone to damage, and proposes a carbon fiber transmission device, as Figure 1 - Figure 2 shown, including a bracket 1, a transmission assembly and a driving assembly.
