DETAILED DESCRIPTION

[0023] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0024] The utility model provides a rotary shearing structure, including an installation frame plate 101.

The bevel gears 208 on both sides respectively drive the transmission shafts 206 on both sides to rotate in opposite directions, wherein the transmission shaft 206 on one side is drivingly connected to the lower longitudinal cutting rotating shaft 202-2 through a chain and a sprocket 210, and the transmission shaft 206 on the other side is drivingly connected to the upper longitudinal cutting rotating shaft 202-1 through a chain and a sprocket 210.

[0027] The large motor 207 is installed under the mounting frame plate, and the rotary power of the longitudinal cutting rotating structure is output through the coupling 207, the transmission shaft 206, the sprocket 210 and the chain of the appropriate length. After the longitudinal cutting rotating structure is positioned, the clamping ring 213 can be locked to prevent the longitudinal cutting rotating shaft from moving left and right, resulting in the blade and the knife plate not contacting and failing to cut.

[0028] The longitudinal cutting blade 203 is designed as a butterfly blade, which is fixed to the clamping sleeve 211 by a spring and a clamping ring, and then passed through the upper longitudinal cutting rotating shaft 202-1. The design of the longitudinal cutting blade plate 204 takes into account the use requirements of the butterfly blade, and adopts a method of setting a certain inclination angle on the edge, which is fixed to the locking sleeve 212 by screws, and then passed through the lower longitudinal cutting rotating shaft 202-2.

After the longitudinal cutting blade 203 and the longitudinal cutting blade plate 204 are close to each other and subjected to force, they are locked on their respective rotating shafts.

[0029] refer to Figure 1 , Figure 3-4 A long hole and a threaded hole are set in the middle section of the mounting frame plate 101 for installing the cross-cutting rotating mechanism. The cross-cutting fixing plate 301 is placed at the bottom, and the lifting cylinder 303 is placed in the middle. The lifting cylinder 303 uses a cylinder with adjustable stroke to achieve height adjustment of the cross-cutting rotating structure. The central opening of the lifting plate 302 is connected to the external thread of the lifting cylinder head. In order to ensure the stability of the lifting plate 302, a guide shaft 311 is set for its alignment.

A small motor 305 is installed on the rear transverse cylinder 304. One end of the transverse rotating shaft 306 is provided with a slot that can be connected to the small motor 305. The other end of the transverse rotating shaft 306 is placed on the front transverse cylinder 304. The transverse cylinder 304 can realize left and right transverse movement of the transverse section, and the small motor 305 drives the transverse rotating shaft 306 to rotate.

[0031] The cross-cutting blade 307 is the same as the longitudinal cutting blade 203. It is fixed on the ferrule and then inserted into the cross-cutting rotating shaft 306. The long holes on the two side vertical plates in the middle section of the mounting frame plate 101 are used to bridge and install the moving plate 309. The cross-cutting blade 307 and the cross-cutting plate 308 are designed to be long and installed on the side of the moving plate 309. After the cross-cutting blade 307 and the cross-cutting plate 308 are adjusted to a position one product away from the center of the longitudinal cutting rotating shaft, they are close to each other and then locked to complete the positioning.
