Description

Technical Field

[0001] The utility model relates to the technical field of flower shearing machines, in particular to a vertical flower shearing machine. Background Art

[0002] After weaving, untwisting or raising, the lengths of the fibers on the surface of velvet fabrics are different, and sometimes the velvet needs to be cut evenly; or the surface loops of knitted terry fabrics need to be cut and evenly cut, which is the purpose of the shearing machine.

[0003] The shearing process can generally be divided into pre-shearing (initial shearing), final (fine shearing) and fancy shearing. Pre-shearing can reduce the pressure of one-time shearing for final shearing and ensure the quality of final shearing. Fancy shearing is to cut the suede into the required pattern, which mainly depends on the type of knife.

[0004] In the prior art, when processing patterns, the shearing effect and style are generally changed by changing the shape of the blade, or the support knife is designed to be different units that can control the height, so as to cut out suede with different patterns. This processing equipment has a complex control program and high requirements on the accuracy of the control equipment, which increases the production cost. Utility Model Content

[0007] A vertical flower shearing machine comprises a machine body and a cloth drop frame and a feeding device arranged on both sides of the machine body, a flower shearing device is arranged in the middle of the machine body, the flower shearing device comprises a round knife, a bottom knife and a flat knife, an adjustment seat is arranged on one side of the round knife, a support seat is arranged on the lower side of the bottom knife, and a fixed seat is arranged on one side of the flat knife; the round knife abuts against the flat knife, the bottom knife is cylindrical, a flower shearing blade is arranged on the outer curved surface of the bottom knife, a sprocket is arranged on one side of the bottom knife, and a transmission chain is sleeved on the sprocket.

[0008] Preferably, spiral blades are evenly arranged on the side curved surface of the circular knife, and the number of the spiral blades is 38 to 44.

[0009] Preferably, the spiral blades abut against the flat blades and are staggered and cross-distributed.

[0010] Preferably, the flower-cutting blade is serrated, and the flower-cutting blade is provided in multiple groups and is evenly arranged on the outside of the base knife.

[0011] Preferably, a control motor is provided on one side of the fuselage, a driving sprocket is provided on the output shaft of the control motor, and the transmission chain is in meshing contact with the driving sprocket.

[0012] Preferably, a swing cylinder is provided at the bottom of the support seat, and the swing cylinder is movably connected to the fuselage.

[0013] The beneficial effects of the utility model are:

[0014] Compared with the prior art, the utility model adopts a cylindrical bottom knife, and the fabric is supported by the shearing blade on the surface of the bottom knife. The fabric can bend sharply at the corner of the tip of the shearing blade, and the tension of the inner and outer layers changes so that the fluff fibers stand upright and enter the blade, thereby improving processing reliability and realizing automated processing.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5A vertical flower shearing machine comprises a machine body 1 and a cloth drop frame 2 and a feeding device 4 arranged on both sides of the machine body 1. A flower shearing device 3 is arranged in the middle of the machine body 1. The flower shearing device 3 comprises a round knife 32, a bottom knife 34 and a flat knife 35. Spiral blades are evenly arranged on the side curved surface of the round knife 32. The number of spiral blades is 38 to 44. The spiral blades are against the flat knife 35 and are staggered and cross-distributed. Since the spiral blades and the flat knife 35 form an inclination angle, the shearing force can be decomposed into a tangential effective force and an axial sliding force. The file pattern on the blade can effectively prevent the axial slippage of the fiber. An adjustment seat 33 is provided on one side of the circular knife 32. A telescopic cylinder is provided on the adjustment seat 33 for adjusting the height of the circular knife 32. A support seat 31 is provided on the lower side of the bottom knife 34. The bottom knife 34 is rotatably connected to the support seat 31. A swing cylinder 30 is provided at the bottom of the support seat 31. The swing cylinder 30 is movably connected to the fuselage 1 and is used to adjust the angle of the support seat 31 to make the bottom knife 34 approach or move away from the circular knife 32. A fixed seat is provided on one side of the flat knife 35.

[0023] The circular knife 32 is against the flat knife 35, the bottom knife 34 is cylindrical, and the outer curved surface of the bottom knife 34 is provided with a cutting blade 341, and the cutting blade 341 is serrated. There are multiple groups of cutting blades 341, and they are evenly arranged on the outside of the bottom knife 34, which is convenient for stretching the cloth and cutting out patterns. A sprocket is provided on one side of the bottom knife 34, and a transmission chain is sleeved on the sprocket. A control motor is provided on one side of the fuselage 1, and a driving sprocket is provided on the output shaft of the control motor. The transmission chain is in meshing contact with the driving sprocket. The control motor controls the rotation of the sprocket through the transmission chain, thereby driving the bottom knife 34 to rotate, which is convenient for processing different patterns.

[0024] The fabric is supported by the shearing blade 341 on the surface of the bottom knife 34, and the fabric can bend sharply at the corner of the tip of the shearing blade 341. The tension of the inner and outer layers changes, so that the fluff fibers stand upright and enter the blade, thereby improving the processing reliability. There is no need to configure high-performance control equipment, and the control accuracy requirement is low. Simple control through a single-chip microcomputer can achieve automated intelligent processing.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
