Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] Specifically, the passive roller 5 can move in the vertical direction under the drive of the external structure to approach the active roller 2 or move away from the active roller 2. A power-carrying part 8 is fixed at one end of the passive roller 5. The power-carrying part 8 is used in conjunction with the magnetic attraction part 9, that is, when the passive roller 5 moves toward the direction close to the active roller 2 and moves into place, the power-carrying part 8 is energized, so that the magnetic attraction part is fixed to the power-carrying part 8 under the action of electromagnetic force and transmits torque, so that the active roller 2 drives the passive roller 5 to rotate through the passive gear 12.

[0035] Preferably, the electromagnetic clutch is a dry single-disc electromagnetic clutch. The dry single-disc electromagnetic clutch is mainly composed of a yoke, a rotor, an armature, a spring sheet, a flange, etc. The yoke coil is energized to generate a magnetic field to attract the armature to generate a friction torque to make the driven part engage or separate, and reset with a specially formed spring sheet. It has a simple structure, a short connection and separation delay time, and a large braking torque. It is suitable for occasions where clutch or positioning requirements are required in mechanical transmission systems.

[0036] In recent years, the market demand for carbon fiber composite materials is growing rapidly due to its unique high strength, low density, corrosion resistance, and anti-aging properties. Prepreg is the basic unit for manufacturing composite materials. Prepreg is an intermediate material that is stored for standby after a certain treatment by impregnating a resin matrix into fibers or fabrics. Wet preparation is one of the main ways to manufacture prepregs. The process principle is that the fabric passes through a resin matrix solution tank in parallel, removes the solvent through a drying treatment, and then is collected on a winding drum. Since wet prepreg has the advantages of relatively simple equipment, convenient operation, and strong versatility, it occupies a place in prepreg manufacturing. In wet prepreg production equipment, a traction roller device is often provided, which plays a role in providing traction to the product and keeping the product running at a uniform speed. Therefore, the connecting mechanism and traction device in this technical solution can be applied to wet prepreg production.

[0042] In this embodiment, refer to Figure 3 , and also includes a pair of guide roller sliders 18, which are respectively fixed on the two side walls of the lifting bearing seat 4 and slidably cooperate with the cylinder fixing seat 6.

[0043] Specifically, a pair of guide roller sliders 18 are slidably connected to the cylinder fixing seat 6 to ensure that the lifting bearing seat 4 is limited so that it can only be lifted and lowered in the vertical direction.

[0044] Further, see Figure 3 A limit block 20 is fixed on the cylinder fixing seat 6, and the limit block 20 is arranged at both ends of the guide roller slider 18 to limit the lifting bearing seat 4.

[0045] In this embodiment, refer to Figure 2 , and also includes a first fixed end cover 13, which is fixed on the end surface of the magnetic attraction part 9 close to the power-carrying part 8 and is configured to position the power-carrying part 8.

[0046] Specifically, the first fixed end cover 13 can be used as a marker, that is, when the passive roller 5 moves toward the active roller 2, by observing the relative position of the end face of the passive roller 5 and the first fixed end cover 13, it can be determined whether the magnetic attraction part 9 and the current-carrying part 8 match each other.

[0047] In this embodiment, refer to Figure 2 , and also includes a passive gear fixing plate 10, which is arranged on one side of the passive roller 5 and fixed to the fixed end of the lifting unit.

[0050] Specifically, the traction device is used to pull an object, and has an active roller 2 and a passive roller 5 that is driven by the active roller 2. The frame 17 serves as a supporting structure to support the fixed plate 3. The active roller 2 is connected to the fixed plate 3 and can only rotate relative to the fixed plate 3. The active roller 2 rotates to drive the active gear 14 to rotate. The active gear 14 meshes with the passive gear 12, and the passive gear 12 drives the magnetic attraction part 9 to rotate. In the working state, the magnetic attraction part 9 is fixed to the power-carrying part 8, and the passive gear 12 transmits power through the electromagnetic clutch.

[0051] The fixing plate 3 is fixed to the frame 17 by bolts. The driving roller 2 is mounted on the fixing plate 3 by another bearing.

[0052] In this embodiment, refer to Figure 1 , Figure 2 , and also includes a driver 1, which is arranged on one side of the frame 17, and the output end of the driver 1 is drivingly connected to the active roller 2.

[0053] Specifically, the driver 1 is used as a power source for the active roller 2 .

[0058] Specifically, the shield 16 is used to cover the driving gear 14 and the driven gear 12 to prevent the driving gear 14 and the driven gear 12 from being exposed.

[0059] Specifically, during the normal production stage, refer to Figure 1 , Figure 2 , the passive roller 5 is in working state, the active roller 2 is in contact with the passive roller 5, there is a product passing between the active roller 2 and the passive roller 5, the power-carrying part 8 is energized, and the magnetic attraction part 9 is in contact with the power-carrying part 8 under the action of electromagnetic force to fix the transmission torque, so that the passive roller 5 and the active roller 2 rotate at the same time.

[0060] In the production preparation stage, refer to Figure 4 , the passive roller 5 is in a separated state, and the passive roller 5 rises under the action of the lifting cylinder 7. At this time, the power-carrying part 8 is in a power-off state, so the power-carrying part 8 and the magnetic attraction part are in a separated state, that is, the power-carrying part 8 rises and falls synchronously with the passive roller 5, and in this process, the separation of the passive gear 12 and the driving gear 14 can be avoided.
