Description

Technical Field

[0001] The utility model relates to the field of composite film production, in particular to composite film cutting equipment. Background Art

[0002] Composite film slitting is a process of cutting wide composite films into narrow widths or specific sizes according to specific requirements. When using the composite film slitting machine, the cutter needs to be installed on the cutter mounting shaft, and the knife holder is installed on the knife holder mounting shaft. The knife holder is used to locate the position of the cutter, and the spacing between multiple cutters can be changed by sliding the knife holder, thereby cutting out composite films of specific sizes. However, the traditional way of adjusting the knife holder is mostly for the operator to use a ruler to measure the spacing between two adjacent knife holders to determine the position of the knife holder. However, this method has the following defects when used: when measuring the knife holder with a ruler, each knife holder needs to be measured with a ruler, which is too time-consuming. After the measurement is completed, the knife holder is easily moved when it is fixed, so it needs to be measured again, which is inconvenient for the operator to use. In response to the above defects: To this end, we propose a composite film cutting device. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a composite film cutting device.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. By setting up a knife holder, placing a first semicircular ring and a second semicircular ring between the two limit rings, and then screwing the limit bolt into the bolt hole, the first semicircular ring and the second semicircular ring can be combined to form a cylindrical sleeve mounted on the knife holder mounting shaft. Since the first semicircular ring and the second semicircular ring are non-standard parts, they can be designed according to the size of the composite film to be cut as needed. Therefore, the combined first semicircular ring and the second semicircular ring can be used to control the spacing between two adjacent limit rings, so that the first semicircular ring and the second semicircular ring of different sizes can be replaced according to the size of the composite film to be cut as needed, and multiple limit rings can be quickly positioned, breaking the defect of traditional measurement using a ruler.

[0019] 2. By setting up a positioning structure, rotating the threaded rod can drive the nut seat to move, thereby driving the positioning block to slide along the inner wall of the strip groove. At the same time, in conjunction with the scale mark, the positioning block can be moved to the required scale. At this time, the position of the positioning block is the starting position of the tool holder. The limit ring is placed against the positioning block, so that the starting position of the limit ring can be quickly determined. Due to the obstruction of the positioning block, the limit ring can be prevented from moving when fixing the limit ring. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] See also Figure 1-5 The utility model provides a technical solution: a composite film cutting device, including: a frame, a cutting structure, and a positioning structure.

[0029] See Figure 1 The frame includes a support frame 1, and a cutting knife mounting shaft 2 and a knife seat mounting shaft 3 which are respectively rotatably mounted on the inner wall of the support frame 1. The front surfaces of the cutting knife mounting shaft 2 and the knife seat mounting shaft 3 are both provided with a plane groove 12.

[0030] The cutting structure includes a cutting knife and a knife seat. The cutting knife includes a fixing ring 9 sleeved on the surface of the knife seat mounting shaft 3, a blade 10 fixedly mounted on one end of the fixing ring 9, and a fixing bolt 11 threadedly connected to the surface of the fixing ring 9. Tightening the fixing bolt 11 can make the threaded end of the fixing bolt 11 contact with the flat groove 12 on the surface of the cutting knife mounting shaft 2, so that the cutting knife can be installed on the cutting knife mounting shaft 2.

[0031] See Figure 2The tool holder includes a limiting ring 4 sleeved on the surface of the tool holder mounting shaft 3, a locking bolt 5 threadedly connected to the surface of the limiting ring 4, and a limiting component sleeved on the surface of the tool holder mounting shaft 3. By tightening the locking bolt 5, the threaded end of the locking bolt 5 can be pressed against the plane groove 12 on the surface of the tool holder mounting shaft 3, and the limiting ring 4 can be fixed on the tool holder mounting shaft 3.

[0032] See Figure 2-Figure 5 The limiting assembly includes a first semicircular ring 6, a second semicircular ring 7 rotatably mounted on the surface of the first semicircular ring 6, a limiting bolt 8 threadedly connected to the surface of the first semicircular ring 6, and a bolt hole opened at one end of the second semicircular ring 7. Both ends of the first semicircular ring 6 and the second semicircular ring 7 are fixedly mounted with plug-ins 18, and both ends of the limiting ring 4 are provided with slots 19 adapted to the plug-ins 18. The first semicircular ring 6 and the second semicircular ring 7 are non-standard parts and can be designed according to the size of the composite membrane to be cut as needed.

[0033] Place the first semicircular ring 6 and the second semicircular ring 7 between the two limiting rings 4, and then screw the limiting bolt 8 into the bolt hole, so that the first semicircular ring 6 and the second semicircular ring 7 can be combined to form a cylindrical sleeve on the tool holder mounting shaft 3. At this time, the insert block 18 will be inserted into the slot 19, thereby preventing the first semicircular ring 6 and the second semicircular ring 7 from shaking.

[0034] Since the first semicircular ring 6 and the second semicircular ring 7 are non-standard parts, they can be designed according to the size of the composite membrane to be cut as needed. Therefore, the combined first semicircular ring 6 and the second semicircular ring 7 can be used to control the spacing between two adjacent limit rings 4, so that the first semicircular ring 6 and the second semicircular ring 7 of different sizes can be replaced according to the size of the composite membrane to be cut as needed, and multiple limit rings 4 can be quickly positioned.

[0035] See Figure 1 、 Figure 3 and Figure 4 The positioning structure is arranged inside the tool holder mounting shaft 3 and is used to adjust the starting position of the tool holder. The positioning structure includes a mounting groove opened at the right end of the tool holder mounting shaft 3, a threaded rod 13 rotatably installed on the inner wall of the mounting groove, a nut seat 14 threadedly connected to the surface of the threaded rod 13, and a positioning block 15 fixedly mounted on the upper surface of the nut seat 14, and the inner top wall of the mounting groove is provided with a strip groove 16 for the positioning block 15 to pass through. The right end of the threaded rod 13 extends to the outside of the tool holder mounting shaft 3 and is provided with a handle 20. Rotating the handle 20 can drive the threaded rod 13 to rotate, and the threaded rod 13 and the nut seat 14 are spirally driven to drive the positioning block 15 to slide along the inner wall of the strip groove 16.

[0036] The surface of the tool holder mounting shaft 3 is provided with a scale mark 17, and the upper end of the positioning block 15 passes through the strip groove 16 and extends to the outside of the tool holder mounting shaft 3. When the handle 20 is turned to drive the positioning block 15 to move, the positioning block 15 can be moved to the required scale by utilizing the cooperation between the positioning block 15 and the scale mark 17. At this time, the position of the positioning block 15 is the starting position of the tool holder. The limiting ring 4 is placed against the positioning block 15, so that the starting position of the limiting ring 4 can be quickly determined, and then the limiting structure and the limiting ring 4 are installed in sequence. Due to the obstruction of the positioning block 15, the limiting ring 4 can be avoided from moving when fixing the limiting ring 4.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any equivalent replacement or change made by a person skilled in the art based on the technical solution and concept of the present invention should be included in the protection scope of the present invention.
