Description

Energy-conservation eight shuttle plastic braiding machines

Technical field

The utility model relates to plastic knitting equipment, particularly a kind of energy-conservation eight shuttle plastic braiding machines.

Background technology

The plastic braiding machine that domestic in the past manufacturing is used, all be to adopt S type cam, the staggered up and down working in reciprocating mode of contact connecting band movable slider (supporting with two slide bars) drives and combines band during transmission, therefore cam must be done very greatly, Heavy Weight, load height, and contact connects the rubber running wheel of cam, because the linear velocity of its operation reaches 3000 rev/mins, so the wearing and tearing of running wheel are quite serious, so service life is short; Slide block and slide bar are sliding frictions, and frictional force is big when up and down reciprocatingly working, and noise is big, also need apply oil, poor working environment during operation; Former plastic braiding machine is when work, and current of electric is about 13 amperes, must use the motor about 5KW, and energy consumption is higher.

The utility model content

The purpose of this utility model is at above-mentioned shortcoming, and a kind of energy-conservation eight shuttle plastic braiding machines are provided.

The technical solution of the utility model is energy-conservation eight shuttle plastic braiding machines, comprise the cam that is installed on the main frame final drive shaft and connect and compose and combine the comprehensive tape handler that band pumps with cam drive, it is characterized in that described cam is eight shuttles, four arc cams, fixedly connected with advancing wheel seat in these eight shuttles, four arc cam tops, this cam is provided with the track that four convex shaped arc circles and four spill circular arc ring slynesses connect and compose; Described comprehensive tape handler is that the track of combining on band linkage and eight shuttles, the four arc cams is in transmission connection.

The arc surface of four convex shaped arc circles and cam cylindrical contour inscribe mutually on described eight shuttles, the four arc cams, the arc surface of four spill circular arc rings is also outer mutually to be cut on the circumference; Described comprehensive band linkage is taken turns by scrolling, connecting rod, slide block, rubber roll, bearing support chassis and expansion bearing seat are formed, the scrolling wheel is fixedlyed connected with comprehensive band both ends and comprehensive tape wrapping is taken turns on the hemicycle side face at scrolling, the scrolling wheel is installed in to be combined on the band Connection Block, combining the band Connection Block is installed on the chassis of main frame, the scrolling wheel flexibly connects with connecting rod again, connecting rod and slide block flexibly connect, slide block is installed on the bearing support chassis, two rubber rolls are installed on the slide block, two rubber rolls are clamped the track on eight shuttles, the four arc cams and are rolled and cooperate, the bearing support chassis is installed on the expansion bearing seat, and the expansion bearing seat is installed on the chassis of main frame.

The utility model has the advantages that because cam is four arc cams, comprehensive tape handler is that the track of combining on band linkage and the four arc cams is in transmission connection, adopting rubber roll to roll with track cooperates, coefficient of friction is very little, reducing noise greatly, and do not need apply oil, so energy-saving effect is remarkable, 4 kilowatts of used main motor currents are saved energy consumption than original braiding machine and are reached more than 25%.

The specific embodiment

With reference to Fig. 1-Fig. 7,1-frame, 2-belt pulley, 3-final drive shaft, 4-bearing block, 5-bearing support chassis, 6-slide block, 7-rubber roll, 8-are combined band Connection Block, 9-scrolling wheel, 10-and are connected framed bent, 11-eight shuttles four arc cams, 12-centre circle, 13-Xiamen circle runway, 14-shuttle wheel, 15-and combine band, 16-size ring, 17-weaving thread, 18-and enclose runway, 19-to the doorstep and combine band arc cincture, 20-and combine band adjuster, 21-fixed gear ring, 22-connecting rod, 23-chassis, 24-and advance wheel, 25-propelling wheel seat, 26-expansion bearing seat.Be optimal way of the present utility model as shown in Figure 1, one of its innovative point is that the cam that will be installed on the main frame final drive shaft 3 is improved to eight shuttles, four arc cams 11, fixedly connected with advancing wheel seat 25 in its top, just cam 11 is with advancing wheel 24 to rotate, as shown in Figure 2, cam 11 has been made four convex shaped arc circles and four spill circular arc ring slynesses connect and compose track; As seen from the figure, the arc surface of four convex shaped arc circles and cam cylindrical contour inscribe mutually on the cam 11, the arc surface of four spill circular arc rings is also outer mutually to be cut on the circumference.As shown in Figure 4, two of innovative point is to combine the situation that the band linkage rolls and is connected by two rubber rolls 7 and cam 11 tracks, rubber roll 7 is installed on the slide block 6, slide block 6 is installed on the bearing support chassis 5, bearing support chassis 5 is installed on the expansion bearing seat 26, expansion bearing seat 26 is installed on the chassis 23 of main frame, slide block 6 flexibly connects with connecting rod 22, connecting rod 22 flexibly connects with scrolling wheel 9 again, scrolling wheel 9 is installed in to be combined on the band Connection Block 8, combining band Connection Block 8 is installed on the chassis 23 of main frame, be with 15 both ends to fixedly connected and comprehensive tape wrapping is taken turns on the 9 hemicycle side faces at scrolling with comprehensive on the scrolling wheel 9, slide block 6 moves back and forth under the drive of cam 11 tracks like this, drives scrolling wheel 9 by connecting rod 22 and back and forth rotates, and is with 15 to move back and forth up and down thereby drive to combine.From Fig. 5, Fig. 6 and Fig. 7, find out the structure of slide block 6 and rubber roll 7.Whole comprehensive band linkage is made up of scrolling wheel 9, connecting rod 22, slide block 6, rubber roll 7, bearing support chassis 5 and expansion bearing seat 26, in conjunction with finding out further among Fig. 4, Fig. 6 and Fig. 7 that the montant that respectively has two tape spools to hold is installed in both sides on the bearing support chassis 5, slide block 6 rolls with the montant upper bearing (metal) and cooperates, and just slide block 6 is moving back and forth between the two bearings on the montant.When final drive shaft 3 rotates, driving eight shuttles, four arc cams 11 rotates, track on the cam 11 drives rubber roll 7, thereby driving slide block 6 horizontally slips, slide block 6 pulling connecting rods 22 drive scrollings wheel 9, and straight reciprocating motion is changed in the reciprocating motion of curve, make that combining pumps to drive to combine with the organizine on 15 with 15 intersects opening up and down, finish braid movement after passing tram, machine continuously turns round and finishes the production of woven bag tube material.Combine on this machine and have 48,4 kilowatts of the powers of motor of use, engine speed are 120 rev/mins, and noise is lower than 65 decibels.Save electric energy than original eight shuttle plastic circular looms and reach more than 25%, reduced noise simultaneously and without lubricating oil, working environment is clean, do not have greasy dirt to dye.
