Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, specifically to a dual-axis center winding automatic cutting device. Background Technology

[0002] Leather is animal hide that has undergone physical and chemical processing, such as hair removal and tanning, to become less prone to decay. Leather is composed of naturally woven protein fibers in a three-dimensional space, with a special grain layer on its surface, giving it a natural grain and luster, and a comfortable feel. Typically, biaxial center-winding automatic cutting is used in leather processing; of course, biaxial center-winding automatic cutting devices can also be used in various industries, such as plastics.

[0003] However, in the existing technology, after the leather or plastic is cut, there is always a 4-5 cm material joint that does not come into contact with the tape on the paper tube. When it is directly wound, the joint will be folded in the core, and the material cannot be evenly spread and adhered to the paper tube, resulting in unqualified material winding and creases. This needs to be further improved.

[0004] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a dual-axis center winding automatic cutting device. Utility Model Content

[0005] The purpose of this invention is to provide a dual-axis center winding automatic cutting device to solve the problems mentioned in the background art.

[0015] As a preferred technical solution, two guide rods are symmetrically installed on one side of the lifting arm, and the two guide rods form a channel for the moving block to slide.

[0016] Compared with the prior art, the beneficial effects of this utility model are: (1) the cutting blade is changed from the traditional disc blade to a hexagonal blade, which is driven to rotate at high speed by a servo motor, and the material is cut at high speed through the rhombus, making the material easy to break and the cut is flat.

[0021] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0022] like Figures 1-2 As shown, this utility model provides a technical solution for a dual-axis center winding automatic cutting device: it includes a frame 1, which is vertically set on the ground. A drive component 2 is hinged on the frame 1. In this embodiment, the drive component 2 is a cylinder. The cylinder is rotatably set on one side of the frame 1 through a mounting base 7. A pressing component is rotatably set on the piston rod of the cylinder.

[0023] The pressing assembly includes a lifting arm 3, one end of which is rotatably mounted on the frame 1. The piston rod of the cylinder is rotatably mounted at the middle position of the lifting arm 3. Through the reciprocating motion of the cylinder piston rod, the cylinder piston rod drives the lifting arm 3 to rotate. A pressing roller 4 is rotatably mounted on the lifting arm 3. Through the rotation of the lifting arm 3, the lifting arm 3 drives the pressing roller 4 to rotate. Before cutting, the cylinder is activated to bring the pressing roller 4 into contact with the product to be cut. The pressing roller 4 automatically retracts the cutting joint and evenly lays it flat and adheres it to the paper tube. Finally, it is wound up normally, and the material has a good curling effect without folding.

[0024] In this embodiment, a cutting assembly is provided on the top surface of the lifting arm 3. The cutting assembly includes a motor 5, which is located on the top surface of the lifting arm 3. A cutting blade 6 is mounted on the output shaft of the motor 5. The cutting blade 6 is a hexagonal blade. When the motor 5 is started, the output shaft of the motor 5 drives the cutting blade 6 to rotate, and the cutting blade 6 cuts the product. The entire cutting process is carried out in an automated manner, which reduces the workload of the workers and saves time and effort. Moreover, the use of a hexagonal blade, driven by the high-speed rotation of the servo motor 5, allows the material to be cut at high speed, making the material easy to break and the cut clean.

[0025] In this embodiment, a connecting block 8 is installed on one side of the lifting arm 3. The connecting block 8 is arranged along the length direction of the lifting arm 3. A threaded hole 9 is opened on the top surface of the connecting block 8. A screw 10 is threadedly connected in the threaded hole 9. A movable block 11 is installed at the top of the screw 10. The movable block 11 is rotatably connected to the pressing rubber roller. When the screw 10 is rotated, the screw 10 drives the movable block 11 to move linearly, which makes it convenient for the user to adjust the position of the pressing rubber roller.

[0026] In this embodiment, two strip-shaped holes 12 are symmetrically opened on one side of the moving block 11, and two threaded holes 13 are symmetrically opened on one side of the lifting arm 3. Bolt 1 is threaded into the two strip-shaped holes and connected to the two threaded holes 13. After the position of the pressing rubber roller is adjusted, the two bolts 1 are threaded into the two threaded holes 13 respectively and fixed to the connecting block and the lifting arm 3.

[0027] In this embodiment, in order to guide the sliding of the moving block 11, two guide rods 14 are symmetrically installed on one side of the lifting arm 3, and the two guide rods 14 form a channel for the moving block 11 to slide.
