DETAILED DESCRIPTION

[0016] To describe the technical content, structural features, purposes and effects of the application, the technical solutions in the embodiments of the present application will be described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. In the following description, for the purpose of explanation, many specific details are set forth in order to provide a thorough understanding of various exemplary embodiments or implementations of the application. However, various exemplary embodiments can also be implemented without these specific details or in one or more equivalent arrangements. In addition, various exemplary embodiments can be different, but not necessarily exclusive. For example, the specific shape, structure and characteristics of an exemplary embodiment can be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0017] ​​The embodiment of the present application provides a power cutter device for a winding machine, which is installed on the winding machine and used for quickly cutting products transversely when the winding machine is full.

[0018] As shown in the figure, the power cutter device comprises an electric cylinder cutter seat 10, a supporting mechanism 20 installed on the electric cylinder cutter seat 10 and a shearing mechanism 30 installed on the supporting mechanism 20. Figure 1

[0019] The electric cylinder cutter seat 10 is connected with an electric cylinder for driving the power cutter device to move transversely as a whole.

[0020] The supporting mechanism 20 comprises a sliding base 1 slidably connected with the electric cylinder cutter seat 10, a cutter mounting plate 2 rotatably connected with the sliding base 1 and a lifting mounting plate 3 slidably connected with the cutter mounting plate 2. The electric cylinder cutter seat 10 is provided with a first sliding groove extending along the front-rear direction, and the sliding base 1 is matched with the first sliding groove, so that the sliding base 1 can move along the front-rear direction in the first sliding groove relative to the electric cylinder cutter seat 10. The cutter mounting plate 2 is hinged with the sliding base 1 through a rotating shaft 4, the rotating shaft 4 has an axis X1 extending along the left-right direction, and the cutter mounting plate 2 can rotate relative to the sliding base 1 about the axis X1. The cutter mounting plate 2 is provided with a second sliding groove extending along a straight line direction, and the lifting mounting plate 3 is matched with the second sliding groove, so that the lifting mounting plate 3 can move back and forth along the straight line direction in the second sliding groove relative to the cutter mounting plate 2, and the straight line direction is perpendicular to the axis X1.

[0021] As shown in the figure, Figure 1 , 2 The shearing mechanism 30 comprises a first circular cutter 5 and a second circular cutter 6 installed on the same side of the lifting mounting plate 3 and a reduction motor 7 installed on the other side of the lifting mounting plate 3, the axis X2 of the first circular cutter 5 and the axis X3 of the second circular cutter 6 are parallel and both perpendicular to the lifting mounting plate 3, the first circular cutter 5 is located on the upper side of the second circular cutter 6, and the cutting edges of the first circular cutter 5 and the second circular cutter 6 have a portion which is mutually interlaced and matched. The reduction motor 7 is drivingly connected with the second circular cutter 6 and used for driving the second circular cutter 6 to rotate about the axis X3. Since the first circular cutter 5 is at least partially matched with the second circular cutter 6, the first circular cutter 5 rotates about the axis X2 in the opposite rotational direction of the second circular cutter 6 under the friction, and the first circular cutter 5 and the second circular cutter 6 rotating in the opposite rotational direction cut the products transversely like scissors.

[0022] ​​The first circular knife 5 is connected with the lifting mounting plate 3 through an elastic pressing device 8, which comprises a circular knife shaft (not shown in the figure), a bearing (not shown in the figure) and a spring 81. The circular knife shaft is rotatably mounted on the lifting mounting plate 3 through the bearing, the first circular knife 5 is coaxially sleeved on the circular knife shaft, and the spring 81 is coaxially sleeved on the circular knife shaft. The spring 81 adheres at least part of the blade of the first circular knife 5 to the second circular knife 6 in the axial direction of the circular knife shaft through its physical properties. The elastic pressing device 8 further comprises a circular knife pressing plate 82 connected to one end of the spring 81, which is located on the side of the first circular knife 5 away from the lifting mounting plate 3, so as to prevent the first circular knife 5 from falling off the circular knife shaft.

[0023] The second circular knife 6 is rotatably mounted on the lifting mounting plate 3 through a cutting knife shaft (not shown in the figure), and a cutting knife spacer 9 is sleeved on the cutting knife shaft to mount the second circular knife 6 on the lifting mounting plate 3, effectively preventing the second circular knife 6 from moving axially.

[0024] As shown in Figure 3 , a U-shaped groove 31 is formed in the lifting mounting plate 3, corresponding to the abutting position of the first circular knife 5 and the second circular knife 6. The U-shaped groove 31 has an opening formed in the side surface of the lifting mounting plate 3, which is located upstream of the shearing mechanism 30 when the power cutter device moves transversely to cut the product, and is used for the product to enter the U-shaped groove 31. The product entering the U-shaped groove 31 is cut off at the abutting position of the first circular knife 5 and the second circular knife 6.

[0025] As shown in Figure 1 , the shearing mechanism 30 is mounted on the lifting mounting plate 3. When the sliding base 1 moves forward and backward, the shearing mechanism 30 adjusts the position in the forward and backward direction. When the knife seat mounting plate 2 rotates around the axis X1, the shearing mechanism 30 can adjust the angle of shearing. When the lifting mounting plate 3 moves in a direction perpendicular to the axis X1, the shearing mechanism 30 can adjust the height of shearing. The supporting mechanism 20 supports the shearing mechanism 30 on the winding machine, and can adjust the shearing position of the shearing mechanism 30 according to the winding path of different products on the winding machine, so that the abutting position of the first circular knife 5 and the second circular knife 6 can be aligned with the product, realizing accurate shearing, improving shearing efficiency, avoiding delay in roll changing time, and further improving winding efficiency.

Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and the scope of protection of the present application is defined by the appended claims, the specification and their equivalents.
