Description

Technical Field

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

[0002] In existing technologies, such as the Chinese utility model patent disclosed in "A Sliding Device for a Packing Machine" with patent number 202420210689.X, a sliding frame is slidably installed on the mounting frame. After removing the fixing bolts on the side of the sliding frame, the sliding frame can be easily slid to the side of the mounting frame, making it easier to remove and replace the sliding blade. This allows for convenient and efficient replacement of the sliding blade, improving the work efficiency of the operator.

[0003] The aforementioned patent also has the following problems in practical application: the replacement of the sliding blade is performed by pulling the sliding bracket out of the mounting bracket, and the sliding bracket and the mounting bracket are fixed with bolts. However, this solution does not provide a positioning guide structure for the threaded hole positions of the mounting bracket and the sliding bracket, which means that after replacing the blade, the position of the sliding bracket must be manually adjusted repeatedly to align the threaded holes of both, resulting in low assembly efficiency and time-consuming and labor-intensive problems. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a slitting mechanism for a slitting machine. It can achieve positioning through the sliding guide of the limit bar and the magnetic attraction. When the sliding frame is fully pushed into the mounting frame and the limit bar slides to the highest point of the slide groove, the threaded hole one of the limit bar, the threaded hole two of the mounting frame, and the threaded groove of the sliding frame are automatically coaxial and collinear. There is no need for repeated manual adjustment of the position, which greatly reduces the alignment time of the mounting frame, the sliding frame, and the threaded hole on the limit bar after the tool change, and significantly improves the assembly efficiency.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A slitting mechanism for a slitting machine includes a mounting frame and a sliding frame. The mounting frame has a slitting inlet, and a pair of push-pull grooves are formed inside the mounting frame. Sliding blocks that slidably connect to the push-pull grooves are provided at both ends of the sliding frame. A cutter assembly is also provided on the sliding frame. When the sliding frame is fully pushed into the mounting frame, its front end face is parallel and coplanar with the front side wall of the mounting frame. A limit bar is slidably connected to the front outer wall of the mounting frame. Positioning grooves are formed at both ends of the mounting frame. The left and right ends of the limit bar... A pair of weak magnetic blocks are fixedly connected to both ends of the right side, and the weak magnetic blocks are slidably connected to the positioning groove. Threaded holes are provided at both ends of the limiting row. Threaded holes are provided at both ends of the mounting frame. Threaded grooves are provided at both ends of the sliding frame. When the sliding frame is fully pushed into the mounting frame, threaded holes one, two, and the threaded grooves are coaxial and collinear. Fixed bolts are provided on the side of the limiting row, which are sequentially screwed to threaded holes one, two, and the threaded grooves. The fixed bolts are used to fix the sliding frame and the limiting row to the mounting frame.

[0009] Furthermore, the inner sidewall of the limiting row is respectively attached to the front sidewall of the mounting frame and the front end face of the sliding frame, and the inner sidewall of the limiting row is set as a smooth surface.

[0010] Furthermore, a second weak magnetic block is embedded in the mounting bracket and on the upper side of the positioning groove, and the first weak magnetic block is located directly below the second weak magnetic block.

[0011] Furthermore, the shapes of the first and second magnetic weakening blocks are matched, and the magnetic poles of the ends of the first and second magnetic weakening blocks that are close to each other are opposite.

[0012] Furthermore, the height of the positioning slide is set to be more than twice the height of the limiting row, and when the weak magnetic block moves to the lowest side of the positioning slide, the upper surface of the limiting row is below the lower surface of the sliding frame.

[0013] 3. Beneficial Effects

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] This solution uses the sliding guide of the limit bar and magnetic attraction to assist in positioning. When the sliding frame is fully pushed into the mounting frame and the limit bar slides to the highest point of the slide groove, the threaded hole one of the limit bar, the threaded hole two of the mounting frame and the threaded groove of the sliding frame are automatically coaxial and collinear.

[0033] Example:

[0034] Please see Figure 1-7 A slitting mechanism for a slitting machine includes a mounting frame 1 and a sliding frame 2. The mounting frame 1 is provided with a slitting inlet and a pair of push-pull sliding grooves 101 are provided inside the mounting frame 1. The left and right ends of the sliding frame 2 are provided with sliders 201 that are slidably connected to the push-pull sliding grooves 101. The sliding frame 2 is also provided with a tool assembly 202. In this solution, the tool assembly 202 includes the first slitting blade, the second slitting blade, and other components on the sliding frame in the cited patent, and the usage and working principle of the above components are described in detail in the cited patent.

[0035] Please see Figure 1-2 When the sliding frame 2 is fully pushed into the mounting frame 1, the front end face of the sliding frame 2 is parallel and coplanar with the front side wall of the mounting frame 1. A limit row 3 matching its specifications is slidably connected on the front outer wall of the mounting frame 1. The inner side wall of the limit row 3 is in contact with the front side wall of the mounting frame 1 and the front end face of the sliding frame 2 respectively. In high-speed cutting scenarios, compared with the single-point bolt connection method without limit row 3, the large area of ​​the limit row 3 in contact with the front end face of the sliding frame can significantly reduce the vibration amplitude and improve the stability during cutting. In addition, the inner side wall of the limit row 3 is set as a smooth surface. The limit row 3 is used to limit the displacement of the sliding frame 2 in the front and rear directions that may occur during assembly, and can also disperse the vibration load of the tool during the cutting process.

[0036] Please see Figure 1-4The mounting bracket 1 has positioning grooves 102 at both ends. A pair of weak magnetic blocks 4 are fixedly connected to both ends of the limiting row 3, and the weak magnetic blocks 4 are slidably connected to the positioning grooves 102. The weak magnetic blocks 4 allow the limiting row 3 to slide up and down along the positioning grooves 102. The height of the positioning grooves 102 is set to be more than twice the height of the limiting row 3. When the weak magnetic blocks 4 move to the lowest point of the positioning grooves 102, the upper surface of the limiting row 3 is below the lower surface of the sliding frame 2. By adjusting the specific position of the limiting row 3 within the positioning grooves 102, the sliding frame 2 can be moved within the mounting bracket 1. The sliding mechanism is limited by the following: threaded holes 301 are provided at both ends of the limiting row 3, threaded holes 103 are provided at both ends of the mounting bracket 1, and threaded grooves 203 are provided at both ends of the sliding bracket 2. When the sliding bracket 2 is fully pushed into the mounting bracket 1, threaded holes 301, 103, and 203 are coaxial and collinear, and the thread specifications of the three types are compatible with the fixing bolts 5. The side of the limiting row 3 is provided with fixing bolts 5 that are sequentially screwed to threaded holes 301, 103, and 203. The fixing bolts 5 are used to fix the sliding bracket 2 and the limiting row 3 on the mounting bracket 1.

[0037] Please see Figure 4-7 A second weak magnetic block 6 is embedded in the mounting bracket 1 and located on the upper side of the positioning slide groove 102. A first weak magnetic block 4 is located directly below the second weak magnetic block 6. The shapes of the first weak magnetic block 4 and the second weak magnetic block 6 are matched, and the magnetic poles of the ends of the first weak magnetic block 4 and the second weak magnetic block 6 that are close to each other are opposite. It is worth noting that the limiting row 3 is made of lightweight material, and the magnetic attraction force generated between the first weak magnetic block 4 and the second weak magnetic block 6 is less than the force required for an adult to press down on the limiting row 3 with their palm. The magnetic attraction force provided by the first weak magnetic block 4 and the second weak magnetic block 6 allows the limiting row 3 to move to the positioning slide groove 102. At the top of 2, it can remain in this position without the help of external force, so as to achieve the effect of automatic coaxiality and collinearity of threaded hole 1 301, threaded hole 2 103, and threaded groove 203, which facilitates the assembly of fixing bolt 5. When the limit row 3 is located at the bottom of the positioning slide 102, there is a large distance between the weak magnetic block 1 4 and the weak magnetic block 2 6. At this time, the magnetic attraction provided by the weak magnetic block 1 4 and the weak magnetic block 2 6 is negligible. Another advantage of the lightweight limit row 3 is that it is easier to push the limit row 3 upward from the bottom of the positioning slide 102.

[0038] Working principle: When some parts of the tool assembly 202 on the sliding frame 2 reach the end of their service life and need to be replaced, firstly, remove the fixing bolts 5 on both sides of the limit row 3, then press down the limit row 3 to move the weak magnetic block 4 to the lowest side of the positioning slide groove 102. At this time, the limit row 3 releases its restriction on the sliding frame 2, and the sliding frame 2 can be pulled out from the mounting frame 1. After replacing the parts, push the sliding frame 2 completely into the mounting frame 1. At this time, the front end face of the sliding frame 2 is parallel and coplanar with the front side wall of the mounting frame 1. Then push the limit row 3 upward. The magnetic attraction provided by the weak magnetic block 4 and the weak magnetic block 6 can assist the limit row 3 in positioning the highest point of the positioning slide groove 102. When the limiting row 3 is in this position, the threaded hole 301, the threaded hole 103, and the threaded groove 203 are coaxial and collinear. Then, the fixing bolts 5 are installed to fix the sliding frame 2 and the limiting row 3 on the mounting frame 1. Compared with the prior art, this utility model uses the sliding guide and magnetic attraction of the limiting row 3 to assist in positioning. When the sliding frame 2 is fully pushed into the mounting frame 1 and the limiting row 3 slides to the highest point of the slide groove 102, the threaded hole 301 of the limiting row, the threaded hole 103 of the mounting frame, and the threaded groove 203 of the sliding frame are automatically coaxial and collinear. There is no need for repeated manual adjustment of the position, which greatly reduces the alignment time of the mounting frame, the sliding frame, and the threaded hole on the limiting row after tool change, and significantly improves the assembly efficiency.

[0039] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
