[0002] In the cold-rolled steel strip processing industry, slitting machines are key equipment for cutting wide cold-rolled steel strips into multiple narrow strips. Existing slitting machines typically use rollers to convey the steel strip and blade rollers to cut it. When the steel strip is delivered to the cutting station, it lacks positioning, making it prone to positional deviation and skewness. This results in substandard dimensions and a significant increase in defective product rates. Furthermore, without the constraints of a positioning mechanism, operators can only manually position the steel strip based on experience. This method is not only inefficient but also difficult to ensure operational consistency, which can easily affect cutting quality. Utility Model Content

[0015] The embodiment of the present utility model is shown in the figure. To achieve the above object, the present utility model provides a slitting machine for cold-rolled steel strips, which includes a machine body 1, at least one blade roller 2 for longitudinally slitting the steel strip, at least one conveying roller 3 for conveying the steel strip, a positioning mechanism is arranged on at least one of the conveying rollers 3, the positioning mechanism is fixedly connected to the conveying roller 3, and the positioning mechanism has an adsorption component capable of adsorbing and positioning the surface of the steel strip.

[0016] When this solution is implemented, the cold-rolled steel strip is placed on the conveyor roller 3. The conveyor roller 3 starts to rotate, driving the steel strip to move towards the blade roller 2. The positioning mechanism is fixedly connected to the conveyor roller 3, and its adsorption component plays a role. Through the adsorption force, the surface of the steel strip is firmly adsorbed and positioned on the conveyor roller 3, preventing the steel strip from shifting, slipping, etc. during the conveying process, ensuring the smooth conveyance of the steel strip. The adsorption component in this solution can be a rubber suction cup 7 or an electric negative pressure suction cup 7 controlled by an air pump. The adsorption method is simple and the manufacturing cost is low. When the steel strip is conveyed to the position of the blade roller 2, the blade roller 2 starts to perform longitudinal cutting operations on the steel strip. After the longitudinal cutting is completed, the conveyor roller 3 continues to rotate. On the one hand, it can convey the subsequent uncut steel strip, and on the other hand, it can convey the cut steel strip to the designated position, completing one longitudinal cutting work process. In this way, the continuous longitudinal cutting process of the cold-rolled steel strip is realized by cycling.

[0017] As a specific improvement implementation, a guide roller 4 is provided between the blade roller 2 and the conveyor roller 3 for guiding the steel strip to the blade roller 2 for longitudinal cutting processing. A driving mechanism for driving the guide roller 4 and the conveyor roller 3 to rotate is provided on the machine body 1, and a guide seat 5 is provided corresponding to the position of the guide roller 4. The guide seat 5 is provided with a correction channel 6 corresponding to the position where the conveyor roller 3 conveys the steel strip. One end of the correction channel 6 is arranged towards the position of the conveyor roller 3, and the other end is arranged towards the position of the guide roller 4.

[0018] When this solution is implemented, the cold-rolled steel strip is placed on the conveyor roller 3, and the driving mechanism is started, driving the conveyor roller 3 and the guide roller 4 to rotate simultaneously. The steel strip moves forward stably under the action of the adsorption and positioning mechanism of the conveyor roller 3, is conveyed by the conveyor roller 3 to the correction channel 6 of the guide seat 5. The correction channel 6 calibrates the traveling path of the steel strip, making it accurately guided to the guide roller 4. After the guide roller 4 receives the steel strip, it stably guides it to the blade roller 2. The blade roller 2 performs longitudinal cutting operations on the steel strip. After the cutting is completed, the steel strip is driven by the conveyor roller 3 and cooperated with the guide roller 4, and is conveyed to the designated position. This solution uses the driving mechanism to provide power, and uses the correction channel 6 and the guide roller 4 to ensure that the steel strip can reach the designated position more accurately, realizing the efficient and precise continuous longitudinal cutting processing of the cold-rolled steel strip.

[0019] As a specific improvement implementation, the adsorption component is a plurality of suction cups 7 made of elastic materials. The plurality of suction cups 7 are evenly distributed on the arc-shaped outer peripheral wall of the conveyor roller 3; a fixing seat 8 for fixing the suction cup 7 is provided at each position of the conveyor roller 3 corresponding to each suction cup 7.

[0020] When this solution is implemented, it is preferably to use an elastic suction cup 7. Those skilled in the art can place the steel belt on the conveying roller 3 so that the weight of the steel belt itself squeezes the suction cup 7 to discharge the air in the suction cup 7 to form a negative pressure space to complete adsorption. This elastic suction cup 7 can be a rubber suction cup 7. The suction cup 7 in this solution is only used to position the steel belt on the conveying roller 3. The conveying roller 3 rolls so that the suction cup 7 on its surface can sequentially adsorb the surface of the steel belt, and the adsorption positioning effect is good. Moreover, the suction cup 7 is connected to the conveying roller 3 through a fixed seat 8, and the connection is more stable, the structure is simple, and the operation is convenient.

[0021] As a specific implementation of the improvement, the driving mechanism includes a motor 9, a transmission belt 10, and a gear 11 is provided for each of the corresponding conveying roller 3 and the guiding roller 4. The transmission belt 10 drives and connects the gear 11 provided for the corresponding conveying roller 3 and the gear 11 provided for the corresponding guiding roller 4. The motor 9 can drive one of the gears 11 to rotate.

[0022] When this solution is implemented, the gear 11 transmits power to the gears 11 provided for the corresponding conveying roller 3 and the guiding roller 4 through the transmission belt 10. Since the transmission belt 10 drives and connects the gear 11 provided for the corresponding conveying roller 3 and the gear 11 provided for the corresponding guiding roller 4, under the meshing transmission of the gears 11, the conveying roller 3 and the guiding roller 4 rotate synchronously. The motor 9 in this solution can mesh with any one of the gears 11 on the conveying roller 3 or the guiding roller 4 for power transmission.

[0023] As a specific implementation of the improvement, the conveying roller 3 is arranged corresponding to the inlet position of the machine body 1, the blade roller 2 is arranged corresponding to the outlet position of the machine body 1, and the conveying roller 3 can convey the steel belt to the position of the blade roller 2.

[0024] When this solution is implemented, it is preferably to arrange the conveying roller 3 corresponding to the inlet position of the machine body 1 and the blade roller 2 corresponding to the outlet of the machine body 1. When the steel belt is placed at the inlet, it directly contacts the conveying roller 3 for conveyance and is output after being cut by the blade roller 2. The process is simple and the operation is convenient.

[0025] The above are only the preferred implementation modes of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
