Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 to 3, a double-station cutting mechanism comprises a material conveying table 1 and a cutting mechanism 2; the two material conveying tables 1 are arranged oppositely at intervals, and the cutting mechanism 2 is positioned between the two material conveying tables 1; the conveying surfaces of the two conveying tables 1 are obliquely arranged towards one side far away from the cutting mechanism 2; the cutting mechanism 2 comprises a bracket 21, a cutting cylinder 22, a moving plate 23 and a cutting knife 24; a rack 26 and a rotary table 27 are arranged in the bracket 21; the cutting cylinder 22 is fixedly connected to the support 21, and the cutting cylinder 22 is connected with the rack 26; the turntable 27 is rotatably connected to the bracket 21, a gear 28 is arranged at the bottom end of the turntable 27, and the gear 28 is meshed with the rack 26; the cutting cylinder 22 is a three-position cylinder; the turntable 27 is provided with a connecting hole 271, and the connecting hole 271 is not coaxial with the turntable 27; the moving plate 23 is connected with the connecting hole 271 through a bolt; the two cutting blades 24 are respectively disposed on two sides of the moving plate 23.

The cutting cylinder 22 is used for driving the rack 26 to move, so as to drive the turntable 27 to rotate by a fixed angle, and further drive the moving plate 23 to move left and right in an eccentric connection manner, so as to drive the cutting knife 24 to cut the product on the conveying table 1 on the left and right sides.

The number of the rotary tables 27 is two, and the rotary tables are arranged at intervals up and down; the moving plate 23 is respectively connected to the connecting holes 271 of the two rotating discs 27 through bolts. The connection hole 271 is used to eccentrically connect the moving plate 33 with the turntable 27, thereby converting the rotation of the turntable 27 into the left and right movement of the moving plate 33.

The moving plate 23 is specifically in an isosceles trapezoid shape, and the two cutting knives 24 are respectively connected to two side surfaces of the moving plate 23.

Two both ends are equipped with striker plate 11 about the defeated material face of defeated material platform 1, and striker plate 11 is used for carrying on spacingly to the both ends about the product on defeated material platform 1.

Cutting grooves 12 are formed in the material conveying surfaces of the two material conveying tables 1; the cutting groove 12 is arranged corresponding to the cutting blade 24.

The working principle is as follows: the products are driven by an external feeding mechanism to move on the two conveying tables 1 respectively; when cutting cylinder 22 and being in the intermediate position, cut mechanism 2 and not cut both sides, reach the fixed length as the product on the defeated material platform 1 of one side, when needing to cut: the cutting cylinder 22 extends out to drive the rack 26 to move, so that the rotary table 27 is driven to rotate for a fixed angle, the movable plate 23 is driven to move leftwards in an eccentric connection mode, and the cutting knife 24 is driven to cut the product on the left conveying table 1; the cutting cylinder 22 retracts to drive the rack 26 to move, so that the rotary table 27 is driven to rotate by a fixed angle, the movable plate 23 is driven to move rightwards in an eccentric connection mode, and the cutting knife 24 is driven to cut the product on the right-side conveying table 1.
