Abstract

The invention relates to a shearing press which belongs to equipment in the sewing industry. The invention aims at providing the shearing press with high production efficiency. The shearing press comprises a rack and has the following structural features: a pulley on a gear box in the rack is connected with the pulley on a motor, the two sides of an output shaft of the gear box are respectively provided with an eccentric wheel, the eccentric wheel at one side is connected with a rocker on a fixed shaft by a connecting rod, a swing bar is connected with a scissor in a chute and corresponding to a fixed cutter on the rack; the eccentric wheel at the other side is connected with a swing screw bolt on the shaft by the connecting rod, a nut on the swing screw bolt is connected with an eccentric shaft on a gear by the adjustable connecting rod, the gear is engaged with the gear on a ratchet wheel on a driving roller, and a driven roller is connected with the shaft and a spring on the rack by the connecting rod.

Description

Cutting machine

Technical field:

The present invention is the equipment that belongs to the industry of sewing.

Background technology:

At present, the cutting off normally of medium-sized and small enterprises band of sewing industry manually finished, and be not only a job of effort, and production efficiency is low.

Summary of the invention:

The present invention is exactly at the problems referred to above, provides a kind of production efficiency high cutting machine.

The present invention adopts following technical scheme: the present invention includes frame, its structural feature is that the gear-box upper belt pulley in the frame links to each other with the belt pulley on the motor, the both sides of the output shaft of gear-box have eccentric wheel respectively, one side eccentric wheel links to each other with the rocking bar on the fixed axis by connecting rod, and fork is with linking to each other corresponding to the scissors in the chute of the dead knife on the frame; The opposite side eccentric wheel links to each other by the coaxial swing screw rod of connecting rod, nut on the swing screw rod links to each other with the eccentric shaft on the gear by adjustable connecting-rod, gear is meshed with the gear on the ratchet on the drive roll, and driven roll links to each other with the axle on the frame, spring by connecting rod.

Beneficial effect of the present invention:

Because the present invention adopts mechanical mechanism to shear band, just can save manpower, has not only guaranteed product quality, and has improved production efficiency greatly.

Description of drawings:

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is that the A of Fig. 2 is to view.

The specific embodiment:

The present invention includes frame 1, gear-box 4 upper belt pulleys 5 in the frame 1 link to each other with the belt pulley on the motor 23, the both sides of the output shaft 6 of gear-box 4 have eccentric wheel 7, eccentric wheel 22 respectively, one side eccentric wheel 7 links to each other with the rocking bar on the fixed axis 9 10 by connecting rod 8, and fork 10 is with linking to each other corresponding to the scissors in the chute 18 of the dead knife on the frame 1 14 16; Opposite side eccentric wheel 22 links to each other by the swing screw rod on the connecting rod 21 coaxial 19 20, nut 30 on the swing screw rod 20 links to each other with the eccentric shaft on the gear 24 28 by adjustable connecting-rod 23, gear 24 is meshed with the gear on the ratchet on the drive roll 11 26 25, and driven roll 12 links to each other with the axle 17 on the frame 1, spring 15 by connecting rod 13.

The present invention can adopt automatic control circuit system 27, and travel switch 29 is arranged, so that the production automation of the present invention.

Below in conjunction with a description of drawings course of action of the present invention:

At first, band places before body 1 upper surface, drive roll 11 and the driven roll 12; Starter motor 2, output shaft 6 rotates, and a side eccentric wheel 7 drives fork 10 motions on the fixed axis 9 by connecting rod 8, and fork 10 just drives scissors 16 and moves up and down corresponding to dead knife 14 along chute 18, promptly to the shearing of band; Meanwhile, opposite side eccentric wheel 22 rotates, drive 20 swings of swing screw rod by connecting rod 21, nut 30 on the swing screw rod 20 rotates by adjustable connecting-rod 23 driven gears 24, gear 25 (to a direction), gear 25 just is with drive roll 11 to rotate, and driven roll 12 is combined closely with drive roll 11 under spring 15 power effects, just spur band and travel forward simultaneously, downcut by scissors 16.

Claims (1)

1, cutting machine, comprise frame (1), it is characterized in that the belt pulley (3) on the same motor of gear-box (4) upper belt pulley (5) (2) in the frame (1) links to each other, the both sides of the output shaft (6) of gear-box (4) have eccentric wheel (7), eccentric wheel (22) respectively, one side eccentric wheel (7) links to each other by the rocking bar (10) on the same fixed axis of connecting rod (8) (9), and fork (10) is with linking to each other corresponding to the scissors (16) in the chute (18) of the dead knife (14) on the frame (1); Opposite side eccentric wheel (22) links to each other by the swing screw rod (20) on the connecting rod (21) coaxial (19), nut (30) on the swing screw rod (20) links to each other by the eccentric shaft (28) on the same gear of adjustable connecting-rod (23) (24), gear (25) on the ratchet (26) on the same drive roll of gear (24) (11) is meshed, and driven roll (12) links to each other by the axle (17) on the same frame of connecting rod (13) (1), spring (15).
