[0017] Reference Figure 1-4 Release paper inspection unwinding brake device includes a frame 1. A cylinder bearing seat 2 and a brake bearing seat 3 are fixed at the top two ends of the frame 1 respectively. A cylinder 4 is fixed on the side wall of the cylinder bearing seat 2. A brake 5 is provided on the side wall of the brake bearing seat 3. An auxiliary braking component 6 is fixed at the bottom of the side wall of the frame 1 and on the same side as the brake 5. A dust cover 7 is fitted and fixed on the side wall of the frame 1 and outside the auxiliary braking component 6. A chain cover 8 is fitted between the dust cover 7 and the brake bearing seat 3.

[0018] Brake 5 is needed to decelerate release paper roller 9 to ensure that the paper maintains tension during the conveying process. An auxiliary braking component 6 is added to share the braking pressure of brake 5 and reduce the wear of brake 5.

[0019] The auxiliary braking assembly 6 includes a first mounting frame 601 and a second mounting frame 602 symmetrically arranged on both sides of the first mounting frame 601. Both the first mounting frame 601 and the second mounting frame 602 are fixed to the side wall of the frame 1. A brake shaft 603 is movably installed between the first mounting frame 601 and the side wall of the frame 1. A brake disc 604 is fixed to the surface of the brake shaft 603. A pneumatic disc brake 605 is fixed to the side wall of the second mounting frame 602. The pneumatic disc brakes 605 on both sides are fitted onto the surface of the brake disc 604.

[0020] The main drive shaft 201 is movably mounted inside the cylinder bearing seat 2. An assembly ring is fitted on the surface of the main drive shaft 201. A spline groove is formed between the assembly ring and the main drive shaft 201, allowing the main drive shaft 201 to move horizontally relative to the assembly ring. A bearing is fixed between the assembly ring and the cylinder bearing seat 2, allowing the main drive shaft 201 to rotate. The driven drive shaft 301 is movably mounted inside the brake bearing seat 3. One end of the main drive shaft 201 is movably connected to the moving end of the cylinder 4. The moving end of the cylinder 4 drives the main drive shaft 201 to move horizontally. The main drive shaft 201 is movably fitted on the surface of the moving end of the cylinder 4, and a bearing is fixed between the main drive shaft 201 and the moving end of the cylinder 4, allowing the main drive shaft 201 to rotate around the center line of the moving end of the cylinder 4. The brake 5 is fixed to one end of the driven drive shaft 301.

[0021] A release paper roller 9 is fixed between the main drive shaft 201 and the driven shaft 301.

[0022] When assembling the release paper roller 9, the cylinder 4 works, and the moving end of the cylinder 4 extends and retracts, driving the main drive shaft 201 to move horizontally. At this time, the distance between the main drive shaft 201 and the driven shaft 301 changes, which can be adjusted in real time according to the required assembly space of the release paper roller 9.

[0023] Both the brake shaft 603 and the drive shaft 301 are fixed with sprockets 606. The two sprockets 606 are mounted on the same vertical plane, and a chain is fitted on the surface of both sprockets 606.

[0024] The brake 5 includes a first semicircular part and a second semicircular part, which are movably connected by an assembly connecting rod and locked by a movable assembly deflection nut.

[0025] Limiting rods 10 are fixed to the side wall of the frame 1, and the limiting rods 10 are arranged on both sides of the connector.

[0026] When using this device, a pneumatic disc brake disc 604 of model SR-20-350 is connected to the bottom of the original brake drum via a chain, and two sets of pneumatic disc brakes 605 of model QZD-70 are installed and enclosed in a sealed housing. Two axial flow fans can be installed for cooling. The operator only needs to adjust the air pressure and does not need to walk back and forth. Even slight contact with the brake 5 will not cause burns. Only a little braking force needs to be added to the original brake, and no adjustment of the equipment is required.
