Description

Technical Field

[0001] This utility model relates to the field of winding mechanisms, specifically to a rewinding mechanism for a carbon fiber cloth rewinding machine. Background Technology

[0002] In the field of carbon fiber material processing, rewinders are widely used as key equipment in the winding of carbon fiber fabrics, and their performance directly affects production efficiency and the quality of finished materials. With the increasing popularity of carbon fiber products in high-end manufacturing, the market has placed higher demands on the ease of operation, specification adaptability, and production continuity of rewinders. How to achieve efficient winding of multi-specification carbon fiber fabrics through structural optimization has become an important direction for the development of rewinder technology.

[0003] Common carbon fiber fabric rewinding machines have several limitations: First, the winding sleeve replacement operation is complex. Traditional clamping mechanisms require manual adjustment of multiple components, which is not only time-consuming but also prone to affecting winding accuracy due to positioning errors. Second, the equipment is not adaptable to carbon fiber fabrics of different widths, usually requiring dedicated winding sleeves or adjustment mechanisms for each specification, resulting in high equipment investment costs. In addition, the power transmission and clamping functions lack coordinated design, requiring machine shutdown for adjustment when changing winding sleeves, affecting production continuity. Finally, existing structures struggle to balance clamping stability and operational flexibility, either causing the winding sleeve to slip due to insecure clamping or reducing operational efficiency due to structural complexity, failing to simultaneously meet the requirements of stable winding and rapid replacement. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned deficiencies and provide a rewinding mechanism for a carbon fiber cloth rewinding machine. This mechanism allows for the quick replacement of winding sleeves of different widths to adapt to the winding of carbon fiber cloths of different widths, thus solving the technical problem of insufficient adaptability of existing technologies to carbon fiber cloths of different widths during winding.

[0005] The objective of this utility model is achieved through the following means:

[0006] A rewinding mechanism for a carbon fiber cloth rewinding machine includes a base plate, a main support mounted on the top side of the base plate, a first motor mounted on the side of the main support, a turntable coaxially connected to the outer end of the rotor of the first motor, connecting rods mounted on both outer sides of the turntable, a cross seat mounted on the outer end of the connecting rods, a ball bearing mounted at the outer center of the turntable, and a main shaft inserted inside the ball bearing, a drive disc coaxially connected to the outer end of the main shaft, a cylinder mounted on the outer side of the turntable, a gear plate connected to the outer end of the cylinder, a gear sleeved on the outer side of the main shaft, an insert plate inserted inside the cross seat, clamping plates connected to the outer ends of the insert plates, a winding sleeve sleeved on the outer side of the clamping plates, and a protrusion mounted on the end of the clamping plates.

[0007] Furthermore, a groove is provided at the inner edge of the base plate, a slider is inserted inside the groove, a secondary bracket is connected to the top of the slider, and a support platform is connected to the outer side of the secondary bracket, which facilitates the limiting of the winding sleeve.

[0008] Furthermore, the support platform is circumferentially fitted with rollers, and the slider is screwed with bolts. The inner end of the bolts is screwed into the inside of the base plate. The added rollers improve the stability when rotating around the sleeve.

[0009] Furthermore, mounting brackets are connected to the sides of both the main bracket and the auxiliary bracket, and a second motor is mounted on the top of each mounting bracket on one side. A lead screw is coaxially connected to the bottom of the rotor of the second motor to facilitate transmission.

[0010] Furthermore, a movable block is inserted inside the mounting bracket, and a mounting plate is connected to the outer side of each movable block. A guide rail is installed in the middle of the outer side of each mounting plate, and a locking block is engaged with the outer side of each guide rail.

[0011] Furthermore, corner brackets are connected to the outside of the card block and the top two sides of the mounting plate, and springs are connected to the inside of the corner brackets. A tension roller is installed on the outside of the card block. The tension roller can be used to easily adjust the tension of the carbon fiber cloth, thus preventing the carbon fiber cloth from folding and deforming during the winding process.

[0012] The beneficial effects of this invention are as follows: The rotation of the turntable driven by the first motor drives the rotation of the cross seat and clamping plate, which in turn drives the winding sleeve to wind up the carbon fiber cloth. Furthermore, the movement of the toothed plate driven by the cylinder drives the rotation of the main shaft, drive plate, and transmission groove through the gears. This, in conjunction with the insert rod, drives the insert plate and clamping plate to expand synchronously, thereby clamping the winding sleeve. This facilitates the quick replacement of winding sleeves of different widths to adapt to the winding of carbon fiber cloths of different widths, improving the adaptability of the rewinding mechanism, shortening the changeover time, and enhancing the continuous operation capability of the equipment. At the same time, it gives the rewinding mechanism good versatility and flexibility. Whether it is narrow or wide carbon fiber cloth, precise winding can be achieved through simple component replacement, eliminating the need for special equipment for different specifications of materials and reducing the investment cost of production equipment.
