Detailed Description

As shown in fig. 1 to 9, the present invention mainly includes a frame 1, a turntable 2, a rotating mechanism, a cutter unit and a stabilizing unit, and the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the frame 1 is an inverted U-shaped structure, and a support base 11 is disposed on the inner side of the frame and fixedly connected to the frame. A fixed shaft 12 arranged above the supporting seat is fixed at the top of the frame, a baffle 13 is fixed at the bottom of the fixed shaft, and the baffle is circular and has a diameter larger than that of the fixed shaft. In order to drive the rotation of the turntable, a rotating motor 14 is arranged at the left end of the supporting seat, and a gear 15 is fixed at the output end of the rotating motor and is meshed with the teeth on the outer wall of the turntable. The supporting seat and the fixed shaft cooperate to support the rotary table and provide support for the rotation of the rotary table in the horizontal plane. The top of the rotary table is provided with a mounting groove, and the lower part of the fixed shaft and the baffle are arranged in the mounting groove. The rotating motor and the gear form a rotating mechanism for driving the turntable to rotate in the horizontal plane.

As shown in fig. 4, the turntable 2 is a circular structure, and four sliding grooves 21 are uniformly arranged on the same circumference at the bottom of the turntable. As shown in fig. 3 and 5, four sliding blocks 3 are arranged at the bottom of the rotating disc, and protrusions 32 are arranged at the tops of the sliding blocks, are arranged in the sliding grooves and are in sliding connection with the sliding grooves. A cutting cylinder 31 is arranged between the bottom of the rotary table and the sliding block, and the sliding block is driven to slide along the sliding groove under the action of the cutting cylinder. The sliding groove is intersected with any radius of the rotary disc.

A cutting knife unit is arranged on the slider, as shown in fig. 5, the cutting knife unit comprises a fixed rod 4 vertically fixed on the slider, a pair of first ear plates 41 arranged on the outer wall of the fixed rod, a swing rod 42 hinged with the first ear plates, a knife rod 43 arranged in parallel with the fixed rod, a pair of second ear plates 44 fixed on the knife rod, a cutting knife arranged at the bottom of the knife rod, a third ear plate 46 fixed on the outer wall of the fixed rod, a fourth ear plate 48 fixed on the swing rod below, and an adjusting cylinder 47 arranged between the third ear plate and the fourth ear plate, wherein the first end of the swing rod is hinged with the first ear plate, the second end of the swing rod is hinged with the second ear plate, and the swing of the swing rod is driven under the action of the adjusting cylinder. The upper end of the cutter bar is provided with a ball 45, and a part of the ball extends out of the cutter bar.

A lifting plate 51 is provided below the turntable, and as shown in fig. 6, a stabilizing cylinder 53 is provided between the lifting plate and the bottom of the turntable, and the lifting plate is driven to move up and down by the stabilizing cylinder. A circular pressing plate 5 is arranged below the lifting plate, and a plurality of pressing springs 52 uniformly arranged along the same circumference are arranged between the pressing plate and the lifting plate. After the position of the cutting knife is adjusted, the driving stabilizing cylinder acts to enable the pressing plate to be in contact with the ball, the cutter bar is pressed under the action of the pressing spring at the moment, and the ball is rotatable relative to the pressing plate at the moment. The pressing plate, the lifting plate, the stabilizing cylinder and the pressing spring form a stabilizing unit, and the stabilizing unit is used for ensuring that the cutter bar is in a stable height state.

As shown in fig. 7, when the adjusting cylinder is driven to act, the oscillating rod can be driven to oscillate, at this time, the four pressure rods move outwards, and the distance between every two adjacent pressure rods is increased.

The method of use of the invention is described below:

(1) when the glass needs to be cut circularly, the adjusting cylinder is driven to act, at the moment, the four pressure rods are close to or far away from each other, the four pressure rods are always positioned on the same circumference, and the four pressure rods are respectively positioned on four peaks of the square shape. The distance between the two pressure rods at the opposite angle positions is equal to the diameter of the cut round glass, then the rotating motor is driven to act, the rotating disc rotates for 90-110 degrees in the horizontal plane, at the moment, the four cutting knives rotate for 90-110 degrees around the center of the rotating disc, and then the round glass is cut.

(2) When the square glass needs to be cut, the adjusting cylinder is driven to act, so that the distance between two adjacent pressure rods is equal to the length of the square glass to be cut; then the driving platen moves down and makes clamp plate and ball contact, and the drive cutting cylinder action at last for cutting knife and glass contact and slide along glass, four cutting knives move along square four limits respectively this moment, and then cut out square glass.

When the position of cutter arbor is adjusted through adjusting air cylinder, the cutter arbor is in different positions, and the high position of cutting knife is also different. At this moment, for satisfying the cutting knife homoenergetic under the different positions and contacting with glass, and glass can not influence moving down of cutting knife again, as shown in fig. 9, be fixed with guide rail 431 at the lower extreme of cutter arbor, the guide rail is open for columniform hollow structure and lower extreme, and the handle of a knife of cutting knife 7 sets up in the guide rail inner chamber, is equipped with ejection spring 71 between cutting knife handle and guide rail, and the guide rail is stretched out to the major part of cutting knife under ejection spring's effect. The larger the swing amplitude of the oscillating bar is, the larger the moving height of the cutting knife is, the maximum compression amount of the ejection spring is, and the larger the positive pressure between the cutting knife and the glass is.

In order to convey the glass, a belt conveyor 6 is arranged below the rack, and the glass moves to and from the position under the rotary table under the action of the belt conveyor.
