Description

Technical Field

[0001] This utility model relates to the field of slitting technology, and more specifically, to a slitting device for steel strip processing. Background Technology

[0002] During the conveying process, the steel strip is prone to wavy undulations, resulting in uneven distance between the steel strip and the cutting surface, which directly affects the cutting accuracy. This fluctuation is mainly due to the unreasonable design of the steel strip coil support structure in traditional equipment. The tension control is unstable during the rotation and release process, causing the steel strip release speed to fluctuate. At the same time, the guide roller system lacks an effective tension adjustment mechanism, which cannot apply uniform tension to the steel strip, resulting in uneven tension of the steel strip during the conveying process.

[0003] Traditional pressure roller structures are usually fixed, and the pressure cannot be precisely adjusted according to the different thicknesses and hardnesses of steel strip materials. When processing thicker or harder steel strips, insufficient pressure causes the steel strip to vibrate and shake during high-speed cutting, while when processing thinner steel strips, excessive pressure may cause the steel strip to deform or be damaged.

[0004] In traditional equipment, adjusting the position of the pressure roller usually requires using a wrench or other tools to loosen the fixing bolts, then manually adjusting the position of the pressure roller, and then tightening the bolts again after adjustment. This method is not only cumbersome and time-consuming, but also prone to inaccurate adjustment due to improper operation. Especially when it is necessary to frequently change steel strips of different specifications, this adjustment method seriously reduces production efficiency. Utility Model Content

[0030] Please see Figures 1-5A steel strip slitting machine includes a cutting frame 1, a pressure roller guiding mechanism, a pressure roller adjusting mechanism, and an adjusting auxiliary mechanism. The pressure roller guiding mechanism includes a side frame 2, a steel strip coil 3, a guide roller 4, a pressure roller 5, and a rotating plate 6.

The annular stepped groove 11 is set on the side wall of the clamping rod 10. The extending spring rod 12 is installed laterally on the side wall of the clamping tube 9. The rotating sleeve 13 is installed on the outer wall of the clamping tube 9. The sealing plate 14 on the rotating sleeve 13 rotates to one end of the extending spring rod 12, so that the extending spring rod 12 is stably engaged in the annular stepped groove 11.

[0031] In this embodiment, firstly, the side frame 2 is installed on the side of the cutting frame 1 to support the steel strip roll 3. The steel strip roll 3 is rotatably mounted on the side frame 2. After the steel strip is released from the roll, it passes through the guide roller 4, which is installed on the side of the cutting frame 1. Both ends are equipped with limiting plates 26 to ensure that the steel strip does not deviate left or right during the conveying process and always stays on the correct track. After being guided by the guide roller 4, the steel strip is further flattened and fixed by the pressure roller 5. The function of the pressure roller 5 is to apply appropriate pressure to the steel strip so that the steel strip is conveyed smoothly to the slitting and cutting assembly 23. The adjusting plate 7 is fixedly installed on one side of the cutting frame 1 and is provided with multiple sets of adjusting holes 8. These adjustment holes 8 are distributed in different positions, corresponding to different positions of the pressure rollers 5. The clamping tube 9 is fixedly installed on the rotating plate 6. When it is necessary to adjust the position of the pressure roller 5, the operator can select a suitable adjustment hole 8, extend one end of the clamping rod 10 through the adjustment hole 8, and engage the other end with the clamping tube 9. The spring rod 12, which is horizontally installed on the side wall of the clamping tube 9, can be engaged in the annular stepped groove 11 to form a stable locking mechanism. In order to ensure that the locking is firm, the operator can rotate the sealing plate 14 on the sleeve 13 to one end of the spring rod 12 to prevent the spring rod 12 from coming out of the annular stepped groove 11, thereby locking the pressure roller 5 in the required position.

[0032] The adjustment auxiliary mechanism includes a locking ball block 15, a base block 16, a spring rod 17, a rod groove 18, a spiral sleeve 19, a spiral groove 20, and a slope ring 21. The base block 16 is installed at the bottom end of the rotating sleeve 13. The spring rod 17 is installed laterally on the outer wall of the retaining tube 9.

The slope ring 21 is installed at the bottom end of the spiral sleeve 19. The locking ball block 15 is installed at one end of the spring rod 12. The slope ring 21 can push the locking ball block 15 to move the spring rod 12 away from the annular stepped groove 11.

[0033] In this embodiment, when the operator rotates the rotating sleeve 13, the spring rod 17 can extend into the rod groove 18 step by step, providing a graded positioning function to ensure that the rotating sleeve 13 can be stably and accurately stopped at the predetermined position during rotation. The spiral groove 20 is set on the outer wall of the locking tube 9. The spiral sleeve 19 and the spiral groove 20 cooperate to slide spirally, realizing more precise position adjustment. The slope ring 21 is installed at the bottom end of the spiral sleeve 19, and the locking ball block 15 is installed at one end of the spring rod 12. When it is necessary to unlock, the operator rotates the spiral sleeve 19, causing it to slide along the spiral groove 20, driving the slope ring 21 to move down, pushing the locking ball block 15, and forcing the spring rod 12 to move away from the annular stepped groove 11, thereby releasing the locking state of the locking rod 10 and the locking tube 9, which is convenient for new position adjustment.

[0034] Please see Figures 1-5 As a supplementary embodiment of a steel strip processing slitting equipment with a pressure roller guiding mechanism, a pressure roller adjusting mechanism, and an adjusting auxiliary mechanism: A base frame 22 is installed at the bottom end of the cutting frame 1, and the base frame 22 is supported in contact with the ground. A slitting cutting assembly 23 is installed on the cutting frame 1. The steel strip is guided to the slitting cutting assembly 23 via the guide roller 4. A roller shaft assembly 24 and a drive roller assembly 25 are installed on one end face of the cutting frame 1, and the pressure roller 5 presses the steel strip against the top end face of the drive roller assembly 25. A limiting plate 26 is installed at both ends of the guide roller 4, and both ends of the steel strip are in contact with the inner side surface of the limiting plate 26. A connecting plate 27 is installed at the bottom end of the side wall of the clamping pipe 9, and the connecting plate 27 is fixedly installed on one end face of the rotating plate 6. A thrust spring 28 is installed at the top end of the inner wall of the clamping pipe 9, and one end of the clamping rod 10 extends into the clamping pipe 9 to compress the thrust spring 28.

[0035] More specifically, firstly, the equipment is stably supported on the ground by the base frame 22 to ensure overall stability. The steel strip coil 3 is installed on the side frame 2. The steel strip is released from the coil and initially guided by the guide roller 4. The limiting plates 26 at both ends of the guide roller 4 ensure that the steel strip does not shift in the lateral position and maintains straight transmission. According to the thickness and hardness requirements of the steel strip, the operator selects the appropriate adjustment hole 8 through the pressure roller adjustment mechanism, inserts the locking rod 10 into the adjustment hole 8 and locks it with the locking tube 9, and at the same time inserts the spring rod 12 into the annular stepped groove 11. The sealing plate 14 on the rotating sleeve 13 rotates to the end of the inserted spring rod 12, locking the inserted spring rod 12 and ensuring the pressure roller... Position 5 is fixed. The spring rod 17 of the adjustment auxiliary mechanism cooperates with the rod groove 18 on the bottom block 16 to provide graded positioning and further ensure the accuracy of rotation locking. After the steel strip passes through the guide roller 4, it enters the channel between the pressure roller 5 and the cutting frame 1. When it is necessary to adjust the position of the pressure roller 5, the operator rotates the spiral sleeve 19, which drives the slope ring 21 to push the locking ball block 15, so that the spring rod 12 extends out of the annular step groove 11 and the lock is released. At this time, the push spring 28 in the clamping tube 9 will push out the clamping rod 10, which is convenient for reselecting the adjustment hole 8 for adjustment.

[0036] In summary, during the use or operation of the overall equipment: when the pressure roller guiding mechanism is required, firstly, the side frame 2 is installed on the side of the cutting frame 1 to support the steel strip roll 3. The steel strip roll 3 is rotated and installed on the side frame 2. After the steel strip is released from the roll, it passes through the guide roller 4. The guide roller 4 is installed on the side of the cutting frame 1, and the two ends are equipped with limiting plates 26 to ensure that the steel strip will not deviate to the left or right during the conveying process and always stays on the correct track. After being guided by the guide roller 4, the steel strip will be further flattened and fixed by the pressure roller 5. The function of the pressure roller 5 is to apply appropriate pressure to the steel strip so that the steel strip is conveyed smoothly to the slitting and cutting assembly 23.

[0037] When the pressure roller adjustment mechanism is in operation, it is used to precisely control the position and pressure of the pressure roller 5. The adjustment plate 7 is fixedly installed on one side of the cutting frame 1 and has multiple sets of adjustment holes 8. These adjustment holes 8 are distributed in different positions and are set for different pressure roller 5 positions. The clamping tube 9 is fixedly installed on the rotating plate 6. When the position of the pressure roller 5 needs to be adjusted, the operator can select a suitable adjustment hole 8, extend one end of the clamping rod 10 through the adjustment hole 8, and engage the other end with the clamping tube 9. The extension spring rod 12, which is installed laterally on the side wall of the clamping tube 9, can be engaged in the annular stepped groove 11 to form a stable locking mechanism. In order to ensure that the locking is firm, the operator can rotate the sealing plate 14 on the sleeve 13 to one end of the extension spring rod 12 to prevent the extension spring rod 12 from coming out of the annular stepped groove 11, thereby locking the pressure roller 5 in the required position.

[0038] When the auxiliary mechanism needs to be adjusted, when the operator rotates the rotating sleeve 13, the spring rod 17 can extend into the rod groove 18 step by step, providing a graded positioning function to ensure that the rotating sleeve 13 can be stably and accurately stopped at the predetermined position during rotation. The spiral groove 20 is set on the outer wall of the locking tube 9. The spiral sleeve 19 and the spiral groove 20 cooperate to slide spirally, realizing more precise position adjustment. The slope ring 21 is installed at the bottom end of the spiral sleeve 19, and the locking ball block 15 is installed at one end of the spring rod 12. When it is necessary to unlock, the operator rotates the spiral sleeve 19, causing it to slide along the spiral groove 20, driving the slope ring 21 to move down, pushing the locking ball block 15, forcing the spring rod 12 to move away from the annular stepped groove 11, thereby releasing the locking state of the locking rod 10 and the locking tube 9, which is convenient for new position adjustment.

[0039] First, the equipment is firmly supported on the ground by the base frame 22 to ensure overall stability. The steel strip coil 3 is mounted on the side frame 2. The steel strip is released from the coil and initially guided by the guide roller 4. The limiting plates 26 at both ends of the guide roller 4 ensure that the steel strip does not shift laterally, maintaining straight-line transmission. The operator selects the appropriate adjustment hole 8 according to the thickness and hardness requirements of the steel strip through the pressure roller adjustment mechanism, inserts the locking rod 10 into the adjustment hole 8 and engages it with the locking tube 9, and simultaneously inserts the spring rod 12 into the annular stepped groove 11. The sealing plate 14 on the rotating sleeve 13 rotates to the end of the inserted spring rod 12, locking the spring rod 12 and ensuring the pressure roller... Position 5 is fixed. The spring rod 17 of the adjustment auxiliary mechanism cooperates with the rod groove 18 on the bottom block 16 to provide graded positioning and further ensure the accuracy of rotation locking. After the steel strip passes through the guide roller 4, it enters the channel between the pressure roller 5 and the cutting frame 1. When it is necessary to adjust the position of the pressure roller 5, the operator rotates the spiral sleeve 19, which drives the slope ring 21 to push the locking ball block 15, so that the spring rod 12 extends out of the annular step groove 11 and the lock is released. At this time, the push spring 28 in the clamping tube 9 will push out the clamping rod 10, which is convenient for reselecting the adjustment hole 8 for adjustment.

[0040] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
