Description

Technical Field

[0001] This utility model belongs to the field of slitting machines, and specifically relates to a slitting mechanism for a slitting machine. Background Technology

[0002] A slitting machine, also known as a slitting line, longitudinal cutter, or strip cutter, is a type of metal slitting equipment. Applications: Suitable for longitudinally shearing metal strips and rewinding the slits into coils. Advantages: Easy operation, high cutting quality, high material utilization, and stepless speed regulation. Structure: Composed of uncoiling, feeding and positioning, slitting, and winding. Applicable materials: Tinplate, silicon steel sheets, aluminum strip, copper, stainless steel plates, galvanized sheets, etc. Applicable industries: Transformers, motors, home appliances, automobiles, building materials, packaging, etc.

[0003] Existing technologies have specifically developed slitting mechanisms for slitting machines. For example, Chinese patent publication number "CN218707900U" discloses "a slitting mechanism for a slitting machine." By pulling a sliding rod, the sliding rod moves and drives a limiting block. The limiting block moves within a limiting groove and compresses an elastic element, thereby separating the limiting block from the handle. Then, pulling the handle drives a rotating rod to move, allowing the rotating rod to be pulled out of the insertion hole, facilitating disassembly, cleaning, and maintenance.

[0004] Although the limit block can be separated from the handle by pulling the slide bar, and then the handle can be pulled to move the rotating rod, thereby pulling the rotating rod out of the insertion hole, which is convenient for disassembling the rotating rod and for cleaning and maintenance, the above-mentioned slitting machine cannot effectively press the material together when slitting. This will result in poor slitting effect and inconvenience in collecting residue, which will increase the need for manual cleaning. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a slitting mechanism for a slitting machine to solve the problems of the slitting machine.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0027] refer to Figure 2 A first U-shaped frame 2 is fixedly installed on the upper end of the base plate 4. A receiving roller 1 is rotatably installed between the ends of the first U-shaped frame 2 away from the base plate 4. A second U-shaped frame 3 is fixedly installed on the upper end of the base plate 4 away from the first U-shaped frame 2. An installation roller 5 is rotatably installed between the ends of the second U-shaped frame 3 away from the base plate 4. The operator can first place the material on the outer ring of the installation roller 5, then pull the head end of the material to the conveying port 7 opened on both sides of the housing 6, and then pull the material into the housing 6 through another conveying port 7. Finally, the cut material is rolled up to the outer ring of the receiving roller 1. This can improve the slitting effect.

[0028] refer to Figure 3 Multiple mounting slots 27 are provided at the bottom of the conveyor ports 7 on both sides. Rubber rollers 15 are rotatably installed inside the mounting slots 27. Rubber rollers 15 can prevent material damage and guide the material direction, which can improve the slitting effect. Two bearings 17 are fixedly installed at the upper end of the housing 6. The bottom of the screw 8 is fixedly installed in the inner ring of the bearing 17. The bearing 17 can provide the rotation effect for the screw 8.

[0029] refer to Figure 4 Both ends of the mounting plate 20 are integrally formed with protrusions 21. Four rectangular grooves 24 are opened on both sides of the inside of the housing 6. The protrusions 21 are slidably installed inside the rectangular grooves 24. The sliding of the protrusions 21 inside the rectangular grooves 24 can improve the stability of the moving frame 9 and help prevent the moving frame 9 from getting stuck when moving. A fixed plate 23 is fixedly installed at the end of the mounting plate 20 away from the moving frame 9. Multiple pressure rollers 25 are rotatably installed inside the fixed plate 23.

A handle 12 is fixedly installed at one end of the drawer 14. When the material is cut, the cutting debris will fall into the waste trough 22 at the bottom of the housing 6. The drawer 14 is slidably installed inside the waste trough 22, so the debris will flow into the drawer 14. The staff can pull the drawer 14 to clean up the debris, which can better collect the waste, improve the cleanliness of the inside of the housing 6, and make it easier to remove the waste.

[0031] Operating principle and advantages: During use, the operator can first place the material on the outer ring of the mounting roller 5, then pull the end of the material to the conveying port 7 on both sides of the housing 6, and then pull the material inside the housing 6 through another conveying port 7. Finally, the cut material is rolled up to the outer ring of the receiving roller 1, which improves the slitting effect. During slitting, the operator can rotate the screw 8 mounted on the upper end of the housing 6, so that the moving frame 9 threaded to the outer ring of the screw 8 can move up and down. When the moving frame moves, it can drive the pressure roller 25 mounted on the bottom of the fixed plate 23 to move towards the material, so that the material fits the blade 19 better and is cut by the blade 19 better, improving the slitting effect. When the material is cut, the cutting debris will fall into the waste trough 22 at the bottom of the housing 6. A drawer 14 is slidably installed inside the waste trough 22, so the debris will flow into the drawer 14. The operator can pull the drawer 14 to clean out the debris, better collect the waste, improve the cleanliness of the inside of the housing 6, and facilitate the removal of waste.
