Abstract

Disclosed is a swing arm type oil-free little cam circular loom, belonging to a plastic braiding machinery. The circular loom is characterized in that a little cam is fixedly installed on a main shaft on the basis of an original circular loom structure, a simple curve lug boss with periodical ascending and declining is arranged on an external circumference of the little cam, an upper plane and a lower plane of the lug boss are contacted with a roller wheel by rolling method, the roller wheel is movably connected with a head of a swing arm, the middle part of the swing arm is movably connected with a swing arm base, the tail part of the swing arm is fixedly connected with a heddle belt, the swing base is fixedly installed on a chassis. The quantity of the roller wheel, an upper roller wheel, the heddle belt, the swing arm, the swing arm base and a lower roller wheel are all 32 or more. The cam is improved to be a small diameter cam, a hyperbolic groove on the cam is improved to be a simple curve lug boss, the sliding friction transmission between the cam and the slider is improved to be rolling friction transmission, all transmission are rolling friction transmission, the whole circular loom does not need lubricating oil to lubricate, the part is not easy to be heated, abrasion is very few, and the production cost is decreased.

Description

Swing arm does not have oily small cam circular weaving machine

Technical field

The utility model relates to the manufacturing of plastic knitting machinery field, particularly swing arm does not have oily small cam circular weaving machine.

Background technology

The circular loom of present domestic manufacturing, sale and use, the hyperbola groove cam of its main frame and the transmission of slide block all are to adopt sliding friction, by the oil pump feed forced feed lubrication, during host work, the transmission of double-slot cam and slide block, relatively line of slide speed is up to 500m/min, and parts very easily generate heat and caused quick-wearing when making frictional drive, influences production efficiency and increase production cost.Plastic flat fiber produces a large amount of plastics dust and enters main frame and sneak into lubricating oil in the braiding process in addition, must be often oil change more, production cost is improved.

The utility model content

The utility model purpose is to improve above-mentioned deficiency, provides the sliding friction transmission of a kind of cam and slide block to be improved to the rolling friction transmission, does not have oily small cam circular weaving machine without the swing arm of lubricating oil.

The technical solution of the utility model is on the basis of former circular loom, improves and realizes.This machine structure comprises belt pulley 1, main shaft 2, spindle drum 3, ring 6 in the size ring, size ring outer shroud 7, gear ring 8, upper roller 9, swatch mill 10, big memorial archway 11, enclose 12 to the doorstep, shuttle 13, button door 15, combine and be with 16, Xiamen circle 17, centre circle 18, bottom roller 21, chassis 22, frame 23, it is characterized in that being fixed with on the main shaft 2 little cam 4, the excircle of little cam 4 is shaped on the periodically simple curve boss of rise and fall, the last lower plane of this boss rolls to contact with roller 5 and is connected, roller 5 is installed in the head and the flexible connection of swing arm 19, swing arm 19 middle parts and swing arm seat 20 flexibly connect, swing arm seat 20 is packed on the chassis 22, and the afterbody of swing arm 19 is with 16 to fixedly connected with comprehensive.

Described roller 5, upper roller 9, combine with 16, the quantity of swing arm 19, swing arm seat 20, bottom roller 21 be 32 or more than.

The utility model is a kind of cam to be improved to the minor diameter cam, hyperbola groove with cam is improved to the simple curve boss again, the sliding friction transmission of cam and slide block is improved to the rolling friction transmission, cancellation lubricating oil and fueller, the swing arm that makes parts be difficult for generating heat, wearing and tearing seldom, reduce production costs does not have oily small cam circular weaving machine.

Fig. 2 is a partial top view of the present utility model

The specific embodiment

Further describe embodiment below in conjunction with accompanying drawing.

With reference to Fig. 1, Fig. 1 is because of left-right symmetry, and a left side half figure draws.Circle, 13-shuttle, 14-warp, 15-buckle door to the doorstep, 16-combines band, 17-Xia Menquan, 18-centre circle, 19-swing arm, 20-swing arm seat, 21-bottom roller, 22-chassis, 23-frame for ring, 7-size ring outer shroud, 8-gear ring, 9-upper roller, the little memorial archway of 10-, the big memorial archway of 11-, 12-in 1-belt pulley, 2-main shaft, 3-spindle drum, the little cam of 4-, 5-roller, the 6-size ring.Belt pulley 1 is packed on the main shaft 2, and main shaft 2 flexibly connects with spindle drum 3 bearings, and main shaft 3 is packed on the chassis 22; Be fixed with little cam 4 on the main shaft 2 again, the excircle of little cam 4 is shaped on the periodically curve boss of rise and fall, lower plane rolls to contact with roller 5 and is connected on this boss, roller 5 is installed in the head and the flexible connection of swing arm 19, the middle part of swing arm 19 and swing arm seat 20 flexibly connect, swing arm seat 20 is packed on the chassis 22, and the afterbody of swing arm 19 is with 16 to fixedly connected with comprehensive; Ring 6 flexibly connects with main shaft 2 bearings in the size ring, and size ring outer shroud 7 is packed on the swatch mill 10; Enclose to the doorstep 12 be packed in swatch mill 10 below, Xiamen circle 17 is packed on the centre circle 18, enclose to the doorstep 12 with Xiamen circle 17 between be placed with 4～8 shuttles 13, the shuttle wheel on the shuttle 13 and upper and lower door enclose 12,17 inclined-plane rolling and contact; Button door 15 is installed on the upper and

lower door circle

12,17; Warp 14 passes the aperture of combining with on 16, combine and to be with 16 structures ringwise, the upper end is enclosed within on the upper roller 9, the lower end is enclosed within on the bottom roller 21, and upper roller 9 is installed on the gear ring 8, and gear ring 8 is packed on the swatch mill 10, swatch mill 10 is packed on the big memorial archway 11, big memorial archway 11 is packed on chassis 22 and the centre circle 18, and bottom roller 21 is installed on the chassis 22, and chassis 22 is packed on the frame 23.

With reference to Fig. 2, little cam 4 is packed on the main shaft 2, on the boss that the excircle of cam 4 is shaped on roll with roller 5 and contact in the plane, roller 5 is installed in the head and the flexible connection of swing arm 19, the middle part of swing arm 19 and swing arm seat 20 flexibly connect, the afterbody of swing arm 19 is with 16 to fixedly connected with combining, and swing arm seat 20 is packed on the chassis 22, roller 5, combine with 16, the quantity of swing arm 19, swing arm seat 20 be 32 or more than.

During host work, motor drives belt pulley 1 makes main shaft 2 rotations, main shaft 2 rotations make little cam 4 rotations that install on it, when little cam 4 rotates, thereby the curve boss of its excircle makes swing arm 19 do periodically to swing up and down to drive to combine is with 16 to pump, combine when being with 16 to pump, make and pass 2 warp 14 alternatively up and down combining with the aperture on 16 and form the openings confession and the shuttle 13 of parallel is housed finishes braiding by opening; Because the last lower plane and the roller 5 of the curve boss that the excircle of little cam 4 is shaped on are the rolling Contact Transmission, and roller 5 is that bearing flexibly connects with swing arm 19, swing arm 19 also is that bearing flexibly connects with swing arm seat 20, all transmissions are rolling friction, institute makes parts be difficult for heating so that complete machine, has been cancelled fueller without oil lubrication, wearing and tearing are few, reduced production cost.
