Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, specifically to a slitting machine with adjustable shearing width. Background Technology

[0002] A slitting machine is a piece of equipment used for processing metal coils. It cuts the metal coil longitudinally, dividing the wide metal strip into several narrow strips, and then rewinds the narrow strips. Different cutting widths can be obtained by adjusting the position of the cutting mechanism, thus improving the adaptability of the slitting machine.

[0003] According to Chinese Patent Publication No. CN220612465U, "An Adjustable Width Strip Sliding Machine," the main feature is the interplay of a movable rod, a limiting block, a second spring, an insert rod, an insert plate, a handle, a clamping rod, a positioning block, a groove, and a first spring. When the user pulls the movable rod, the movement of the movable rod causes the limiting block to move, which in turn causes the second spring to move. This movement of the second spring then causes the insert rod to move, disengaging it from the insert plate. Pulling the handle causes the positioning block to slide within the clamping rod, disengaging it from the groove. This allows for adjustment of the width between the cutting blades. Once adjusted, the positioning block is fixed in the groove by the action of the first spring, and the second spring's elasticity fixes the insert rod in the insert plate, preventing the positioning block from moving during operation and thus ensuring the cutting blade's stability.

[0004] Common adjustable shearing machines mainly achieve stepless adjustment of the blade spacing through ball screws and sliders. The blade spacing can also be adjusted through fixed plates, grooves, and positioning blocks. However, the cutting spacing of the blades depends on the subdivision of the grooves on the fixed plate. Different cutting requirements require different fixed plates and groove spacings. In addition, after replacing the fixed plate, the position of the blades also needs to be calibrated, making width adjustment quite troublesome. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a slitting machine with adjustable cutting width to improve the efficiency of blade spacing adjustment and reduce calibration time.

[0006] The technical solution adopted by this utility model to solve the technical problem is as follows: a slitting machine with adjustable cutting width, including a bottom frame and an upper frame. A bracket is fixedly connected to the bottom frame and the bracket is movably inserted into the upper frame. An adjusting rod is rotatably connected to one side of the bottom frame and threadedly connected to the upper frame. A first motor is fixedly connected to both the bottom frame and the upper frame. A lead screw is fixedly connected to the output end of the first motor. A slider is threadedly connected to the lead screw. A second motor is fixedly connected to one side of the slider. A cutting wheel is fixedly connected to the output end of the second motor. A first groove is provided on both the bottom frame and the upper frame. A marking block contacts the first groove. The marking block corresponds to the position of the cutting wheel. A scale is provided on one side of the first groove on the bottom frame and the upper frame. A shift block is sleeved on the lead screw. A groove is provided on the upper end of the shift block and a contact pressure roller is fixedly connected to the groove.

[0007] As a preferred technical solution of this utility model, a support rod is fixedly connected between two adjacent moving blocks. The support rod is located on one side of the slider. By setting the support rod, the moving blocks 10 can move synchronously.

[0008] As a preferred technical solution of this utility model, a sliding ball is rotatably embedded on the moving block, and the sliding ball contacts the upper frame and the bottom frame respectively. By setting the sliding ball, the friction force of the moving block is reduced.

[0010] As a preferred technical solution of this utility model, a connecting rod is fixedly connected to one side of the bottom frame, and a support frame is fixedly connected to one end of the connecting rod. A limiting groove is opened on the support frame, and a limiting rod is fixedly connected in the limiting groove. A spring is sleeved on the limiting rod, and the bottom end of the spring contacts a pressure block. The pressure block is sleeved on the limiting rod, and an auxiliary roller is rotatably connected to the pressure block.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3 The slitting machine with adjustable cutting width shown includes a base frame 1 and an upper frame 3. A bracket is fixedly connected to the base frame 1 and movably inserted into the upper frame 3. An adjusting rod 2 is rotatably connected to one side of the base frame 1 and threadedly connected to the upper frame 3. A first motor is fixedly connected to both the base frame 1 and the upper frame 3. The first motor drives a lead screw 4 to rotate, which causes a slider 5 to move within the upper frame 3 and the base frame 1. The output end of the first motor is fixedly connected to the lead screw 4, and the slider 5 is threadedly connected to the lead screw 4. A second motor is fixedly connected to one side of the slider 5. The second motor drives a cutting wheel 6 to rotate. Under the monitoring of a distance sensor 14, the second motor can control the rotation of the cutting wheel 6. The motor starts, aligning the two cutting wheels 6 that are opposite each other. The output end of the second motor is fixedly connected to the cutting wheel 6. The bottom frame 1 and the upper frame 3 are both provided with a first groove 7. The first groove 7 contacts a marker block 8. The marker block 8 corresponds to the position of the cutting wheel 6. The bottom frame 1 and the upper frame 3 are provided with a scale 9 on one side of the first groove 7. The scale 9 makes it easy for people to observe the position of the marker block 8. A moving block 10 is sleeved on the lead screw 4. The upper end of the moving block 10 is provided with a groove, and the pressure roller 11 is fixedly connected in the groove. The pressure roller 11 is located on both sides of the cutting wheel 6, which can improve the cutting stability after adjusting the width.

[0018] Among them, a support rod 12 is fixedly connected between two adjacent moving blocks 10. The support rod 12 is located on one side of the slider 5. By setting the support rod 12, a synchronous structure is formed, which can make the two moving blocks 10 move synchronously.

[0019] Among them, the sliding block 10 is rotatably embedded with a slider 13, which contacts the upper frame 3 and the bottom frame 1 respectively. By setting the slider 13, the friction between the sliding block 10 and the upper frame 3 or the bottom frame 1 can be reduced when the sliding block 10 moves.

[0020] Among them, a distance sensor 14 is fixedly connected to one side of the moving block 10. The distance sensor 14 corresponds to the upper frame 3 and the bottom frame 1 respectively. At the same time, a recess is opened at the corresponding position of the moving block 10 and the distance sensor 14. The distance sensor 14 provides a distance signal between the moving block 10 and the upper frame 3 or the bottom frame 1.

[0021] Among them, a connecting rod 15 is fixedly connected to one side of the bottom frame 1, and a support frame 16 is fixedly connected to one end of the connecting rod 15. A limit groove 18 is opened on the support frame 16, and a limit rod 20 is fixedly connected in the limit groove 18. A spring is sleeved on the limit rod 20, and the bottom end of the spring contacts a pressure block 19. The pressure block 19 is sleeved on the limit rod 20, and an auxiliary roller 17 is rotatably connected to the pressure block 19. By setting two auxiliary rollers 17, the stability of the metal strip movement can be ensured under the action of gravity and spring during subsequent traction.

[0022] Working principle: The width signals of multiple cutting wheels 6 are adjusted according to the width of the metal strip. Then, the distance sensor 14 monitors the distance signal between the slider 5 and the upper frame 3 or the bottom frame 1. At the same time, the position of the cutting wheel 6 is determined by the marker block 8 and the scale 9. Then, the pressure roller 11 is used to squeeze the metal strip during cutting and pass the metal strip through the auxiliary roller 17 to provide further limit and improve cutting stability.
