Description

A kind of framing cutter of loom

Technical field

The utility model relates to mechanical, be particularly related to a kind of framing cutter of loom, it is to be rotated by the direct outputting power of a motor to cut blade, cut cloth by the round blade of high speed rotating, and cooperate a microswitch as safety switch, prevent that cloth from constantly destroying cloth and weaving cotton cloth board because of cutting.

Background technology

Development along with society, the continuous progress of science and technology, textile technology improves constantly, and improves relatively for the quality requirements of fabric, the flaw that reduces cloth that loom weaves with keep the cloth integrality, and to reach more efficient manufacturing by new construction be the index of modern times requirement with the board security; The framing cutter of old loom is with the mechanical scissor device, be to utilize loom both dynamic through linkage, with power transfer on it upper and lower cutter and the seat, just shear action used for opening and closing, wherein this scissors apparatus be can two be one group, place the and arranged on left and right sides of weaving loom respectively, and respectively be subjected to interlinked mechanism institute interlock; Wherein this left side scissors apparatus includes a locking seat, is provided with upper and lower knife edge seat; One holder, can in order to the existing mechanism of weaving loom Joint; One pedestal can make above-mentioned locking seat, holder matrix provided thereon; One rocking handle portion is to set up with aforementioned knife edge seat is coaxial, and interlock mutually; The member combination that mat is above-mentioned when rocking handle portion is subjected to interlock, can drive the shear action that the knife edge seat that locks on the seat is made open and close; The shortcoming of said structure is that this scissors apparatus is with the linkage outputting power, its knife edge seat is opened, the shear action of closing is to drive by a rocking handle portion to reach, when relative rocking handle portion action is not smooth, opening of knife edge seat, the shear action of closing promptly can't be finished cloth cutting smoothly, and it there is no the safety protection structure setting, in case even blade uses or axle center Bearing fault motor when damaging because of permanent, can't cut cloth smoothly, therefore whole of mechanical scissor device can be pressed to draw to cause damaging by the cloth of output at a high speed backward fracture, even therefore make loom and other interlock damage parts and, cause the loss of manufacture process very big with the cloth damage.

The utility model content

The utility model is to improve at the shortcoming that the framing cutter of common loom exists, main purpose is to increase speed of cut and improve security, its structure be meant be used for loom weave cotton cloth finish after, the cloth that rolls out is directly cut the cutter of framing, mainly by a tool rest, one motor, one circular shear blade, one protecting cover, one locking handle combination forms, wherein, cutter passes axle center and motor binding by the built-in circular shear blade of a tool rest through a power transmission shaft, tool rest one end is connected a protecting cover by a contiguous block with spring, and the tool rest back side be provided with one the locking handle combination become cutter structure; Be provided with a next-door neighbour microswitch in addition at the nearly contiguous block of tool rest place, utilize microswitch detecting protecting cover to launch transmission parking message in loom; Directly rotate circular shear blade via motor and reach the framing action that cuts cloth fast.

The specific embodiment

Shown in accompanying drawing 2 and accompanying drawing 3, framing cutter for a kind of loom, constituted by motor 1, tool rest 2, circular shear blade 21, locking handle 3, protecting cover 4, spring 5, contiguous block 6, microswitch 7, wherein, circular shear blade 21 is to place in the tool rest 2, pass the combination of its axle center by a power transmission shaft 23, and tool rest 2 and a handle 3 that locks combines cutter; Power transmission shaft 23 drives circular shear blade 21 quick rotation to reach the function that cuts cloth by the motor 1 direct outputting power that is assembled in tool rest 2 back sides; In addition, tool rest 2 has a peristome to make circular shear blade 21 expose outside a part, this exposed section is covered by a protecting cover 4 and only holds one and cuts mouth 22, wherein protecting cover 4 one ends are linked by a contiguous block 6 and tool rest 2, be provided with a microswitch 7 at tool rest 2 back sides and protecting cover 4 junctions, the outlet line of this microswitch 7 is connected to loom, and microswitch 7 can transmit the power switch that the parking signal is given loom by this.

As shown in Figure 5, for framing cutter safeguard construction amplifies circle, wherein, be located at tool rest 2 back sides by a microswitch 7, and this microswitch 7 touch button 71 just and contiguous block be close to, when circular shear blade 21 has damage to cause it to cut cloth smoothly, this cloth can hinder and can't framing be pushed open by protecting cover 4 because of being hampered, the contiguous block 6 that is linked to 2 of protecting cover 4 and tool rests can be raised because of protecting cover 4 is an angular turn, touch button 71 via what the rotation one end of contiguous block 6 can escape to microswitch 7, touch button 71 this moment thereby flick and the parking message is transferred to the main switch of loom, and make loom stop the everything of board, can prevent that thus cloth from continuing to bestow the framing cutter with pressure, therefore can prevent the damage and the related damage that prevents the relevant interlock part of cloth of framing cutter with loom.

As shown in Figure 3, schematic side view for the framing cutter, wherein tool rest 2 is made up of two plate bodys, this two plate body becomes equidistant width that circular shear blade 21 is enveloped, pass the axle center of tool rest 2 and circular shear blade 21 via a power transmission shaft 23, these power transmission shaft 23 1 ends are by the direct transmission power of motor 1, and power transmission shaft 23 other ends pass that tool rest 2 locks with a bearing 24 and add strong fix so that screw is laterally inserted; Again; tool rest 2 outsides one end colludes and hangs with microscler spring 5; these spring 5 other ends collude and are hung on the protecting cover 4; its role is to the elasticity positioning action that prevents that protecting cover 4 from excessively raising; protecting cover is linked by contiguous block 6 and tool rest 2; as do not have this spring 5 and locate; protecting cover 4 can be raised arbitrarily and rock; protecting cover 4 can be positioned certain position by this spring 5; the protection blade does not excessively expose; and can make 4 rounds clothes of protecting cover raise Shi Youyi buffering flip action, avoid making operating personnel to hurt, and when protecting cover 4 bears outside, can become an expansion positioning function during pressure-lift power.

As shown in Figure 1, be framing cutter setting position schematic diagram, wherein, power resources are given the motor 1 of framing cutter by the power supply A transferring electric power of loom, this motor 1 transmits power immediately in power transmission shaft 23, rotate circular shear blade 21 by power transmission shaft 23 and be high speed rotating, because of circular shear blade 21 high speed rotating can extremely fast cut cloth, be the round cutting-off tool sheet 21 tool securities that make the framing cutter, therefore coat by tool rest outside the circular shear blade 21, this tool rest only covers circular shear blade 21 about 2/3rds parts, circular shear blade 21 is in addition 1/3rd for exposing to outside the tool rest 2, be linked to tool rest 2 breach for cutting mouthfuls 22 by one again, this cuts mouthfuls 22 is to contact with circular shear blade 21 and reach the action that cuts cloth for holding cloth.
