Description

Technical Field

[0001] The invention relates to the technical field of thin material cutting technology, in particular to a coal blocking glue cutting and forming device. Background Art

[0002] At present, thermal power plants advocate the use of old and recycled materials. They manually use utility knives to cut the old conveyor belts into strips to serve as guide troughs to block coal glue. However, the old conveyor belts have nylon and steel wire inside that are difficult to cut. Cutting with a utility knife is not only time-consuming and laborious, but also causes uneven cutting of the containers.

[0003] In the field of thermal power generation, with the improvement of environmental awareness and the strengthening of cost control needs, repairing and reusing waste has become an important measure. Among them, it is a common operation to cut the old conveyor belts into strips and use them as coal glue in the guide trough.

[0004] However, due to its own special structural characteristics, the old conveyor belt poses great challenges to the cutting work. The belt contains nylon and steel wire materials. These high-strength materials greatly increase the difficulty of cutting. When manually cutting with a utility knife, on the one hand, it takes a lot of manpower and time costs. The workers perform cutting operations for a long time, their hands are easily fatigued, and the cutting efficiency is low, which makes it difficult to meet the demand for the amount of coal-blocking glue in actual production. On the other hand, due to the limitations of the utility knife and the instability of manual operation, the edges of the cut coal-blocking glue are uneven, and the dimensional accuracy is difficult to guarantee. This not only affects the sealing effect and performance of the coal-blocking glue in the guide trough, but also may cause the coal-blocking glue to be easily damaged during use due to cutting quality problems, shortening its service life, and increasing the cost of maintenance and replacement. Therefore, there is an urgent need for a coal-blocking glue cutting and forming device to improve the processing quality and efficiency of the coal-blocking glue. Summary of the invention

[0005] The purpose of the present invention is to provide a coal-blocking glue cutting and forming device to improve the efficiency of cutting thin materials and effectively save labor.

[0006] The present invention provides a coal-blocking glue cutting and forming device, comprising a movable diversion support frame, wherein two mutually cooperating cutting rollers are rotatably mounted on the front end of the diversion support frame, a driving device for driving the two cutting rollers to rotate is mounted on the diversion support frame, and two limit sleeves which can be moved and adjusted along the axial direction thereof are sleeved on the cutting rollers.

[0007] Furthermore, the diversion support frame includes a base plate and two guide plates respectively used to divert flow to both sides, the bottom end of the base plate is symmetrically installed with movable wheels, the two guide plates are symmetrically installed at the top of the base plate, and the two cutting rollers are mounted at the front end of the intersection of the two guide plates.

[0008] Furthermore, the driving device comprises a motor, and the motor is mounted above the cutting rollers. The two cutting rollers are respectively provided with mutually meshing transmission gears, and the motor is transmission-connected to one of the cutting rollers.

[0009] Furthermore, the output shaft of the motor is connected to one of the cutting rollers via a chain drive.

[0010] Furthermore, the output shaft of the motor is connected to one of the cutting rollers via a belt drive.

[0011] Furthermore, the output shaft of the motor is connected to one of the cutting rollers via a gear transmission.

[0012] Furthermore, a connecting frame is provided between the two guide plates, and a handle is installed on the connecting frame.

[0013] Furthermore, the handle and the connecting frame are connected via a universal joint.

[0014] Furthermore, the cutting roller comprises a roller shaft and a cutting wheel, and the cutting wheel is arranged at a middle position of the roller shaft.

[0015] Furthermore, the limiting sleeves are respectively sleeved on both sides of the cutting wheel on the roller shaft, and an adjustment groove is opened on the roller shaft along its length direction, and the inner side of the limiting sleeve is fitted in the adjustment groove.

[0016] The beneficial effects of the technical solution are as follows: the solution adopts a movable diversion support frame, so that the device can be flexibly moved between different working areas, which is convenient for cutting old conveyor belts. There is no need to frequently move the belts, which greatly saves time and labor costs. Two mutually coordinated cutting rollers are arranged to rotate relative to each other under the drive of a driving device, so that the old conveyor belts can be quickly cut. Compared with the manual use of a utility knife, the cutting speed is greatly improved; two limit sleeves that can be moved and adjusted along the axial direction of the cutting roller can accurately adjust the cutting width according to different size requirements to ensure that the cut coal-blocking glue has high size accuracy and neat edges.
