Description

Technical Field

[0001] The utility model relates to the technical field of feeding roller brakes, and specifically relates to a feeding roller brake device for a slitter. Background Technique

[0002] The feeding roller of a slitter is an important part of the feeding system of the slitter. Through its rotational movement, the feeding roller stably feeds raw materials (such as paper, plastic film, fabric, etc.) into the working area of the slitter, ensuring that the raw materials do not shift or vibrate during the cutting process, and ensuring the accuracy and consistency of cutting.

[0003] The existing feeding roller brake device of a slitter uses pneumatic brake pads, and its working principle is based on pneumatic control and friction braking principles. When braking is required, a signal is sent to the pneumatic brake device through the control system, and the air compressor transports compressed air into the cylinder of the brake device. As the air pressure increases, the piston in the cylinder pushes the brake pads to tightly press against the roller body of the feeding roller, thereby generating frictional force and quickly stopping the rotation of the feeding roller to achieve the braking effect. However, when the heat generated by the friction between the brake pads and the feeding roller is too high, it will cause damage to the brake pads and the feeding roller, such as increased wear of the brake pads, increased surface temperature of the feeding roller, or even deformation, which will affect the performance and stability of the brake device. Therefore, we need to propose a feeding roller brake device for a slitter. Content of the Utility Model

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0020] Please refer to Figures 1-3 , the present invention provides a technical solution:

[0021] A braking device for the feeding roller of a slitter, including a mounting frame 1. Two groups of positioning seats 18 are fixed on the top of the mounting frame 1. Two groups of rotating rods 2 are movably installed in the two groups of positioning seats 18. A feeding roller 3 for feeding materials is installed on the two groups of rotating rods 2. One end of one group of rotating rods 2 is fixedly installed with a second synchronous pulley 17;

[0022] It should be noted that a driving device for driving the feeding roller 3 to rotate is provided on the side of one group of positioning seats 18. When the feeding roller 3 rotates, materials can be fed.

[0023] A fixing frame 4 is fixedly installed on the top of one group of positioning seats 18. An adjusting mechanism is arranged in the fixing frame 4. A generator 14 is arranged on the adjusting mechanism. A first synchronous pulley 16 is arranged on the output shaft of the generator 14. A synchronous belt 8 is arranged on the first synchronous pulley 16 and the second synchronous pulley 17. The second synchronous pulley 17 is driven by the synchronous belt 8 to be in transmission with the first synchronous pulley 16.

[0024] In an optional embodiment: the adjusting mechanism, the adjusting mechanism includes a lead screw 5, a lifting plate 6 and a connecting frame 13. The lead screw 5 is movably installed in the fixing frame 4. The lifting plate 6 is threadedly installed on the lead screw 5. The connecting frame 13 is fixedly installed on the side of the lifting plate 6. The generator 14 is fixedly installed on the side of the connecting frame 13. The upper end of the lead screw 5 is fixedly installed with a handwheel 12.

[0025] It should be noted that the lead screw 5 can be rotated by the handwheel 12, so that when the lead screw 5 rotates, it can drive the lifting plate 6 to move. When the lifting plate 6 moves, it can drive the generator 14 to move. Thus, when the generator 14 moves, it can drive the first synchronous pulley 16 and the second synchronous pulley 17 to approach or move away from each other, so as to facilitate the replacement of the synchronous belt 8.

[0026] In an optional embodiment: a positioning rod 7 is fixedly installed in the fixing frame 4. The lifting plate 6 is slidably installed on the positioning rod 7.

[0027] It should be noted that by the cooperation of the lifting plate 6 and the positioning rod 7, the positioning of the lifting plate 6 can be realized, so that the lifting plate 6 can move stably.

[0029] It should be noted that when installing the feeding roller 3, when the fixing block 9 is placed in the support groove 11, the feeding roller 3 can be supported by the support groove 11, and by the cooperation of the fixing screw and the fixing block 9, the feeding roller 3 can be fixedly installed on the rotating rod 2.

[0030] In an alternative embodiment: the output shaft of the generator 14 is fixedly installed with a connecting rod 15 through a coupling, and the first synchronous pulley 16 is fixedly installed at the end of the connecting rod 15.

[0031] It should be noted that when it is necessary to brake the feeding roller 3, the driving device stops driving the feeding roller 3. By the cooperation of the rotating rod 2, the second synchronous pulley 17, the synchronous belt 8, the generator 14, the first synchronous pulley 16 and the connecting rod 15, a resistance can be applied to the feeding roller 3, so as to realize the braking of the feeding roller 3;

[0032] In addition, when the feeding roller 3 rotates, the generator 14 recovers and generates electricity from the kinetic energy through the cooperation of the rotating rod 2, the second synchronous pulley 17, the synchronous belt 8, the first synchronous pulley 16 and the connecting rod 15, improves the energy utilization efficiency, reduces the equipment heating, and thus can improve the service life of the device.
