Abstract
The invention discloses a cam for a plastic circular weaving machine, which comprises a cam seat and a cam ring arranged on the cam seat. The cam ring is formed by assembling two or more than two arc guide plates, and the outer peripheral surface of each of the arc guide plates is provided with a cam groove. The cam for the plastic circular weaving machine adopts an assembled cam structure, that is, the cam consists of the cam seat and the cam ring, and the cam ring is formed by assembling a plurality of the arc guide plates, so the arc guide plates made of light high-performance materials such as engineering plastics can be realized; and on the premises of ensuring strength and abrasion resistance of the cam unchanged, weight and rotary inertia of the cam are lightened greatly, staring and stopping performances of the weaving machine are improved, and the cam achieves the effects of reducing woven scrap rate, saving electrical energy and reducing cost.
Description
[technical field]
The present invention relates to the plastic circular loom field, relate in particular to the cam in the plastic circular loom.
[technical background]
Plastic circular loom cam mostly is to adopt the monoblock type cast iron materials to make or adopt independent cam disc and the combination of curve rail to install to form at present.Practical application all is monoblock type cast iron structure in the industry, and cam Heavy Weight, rotary inertia are big, make loom start difficulty, shut down slowly; starting difficulty causes power consumption big; shut down and slowly make loom percent defective height, thereby influence loom characteristic, and the unitary cam manufacturing cost is very high.Chinese patent CN2172297Y discloses a kind of plastic circular loom combined type cam disc; adopt steel processing back recombinant to install separately cam disc and curve rail; solved curve rail short problem in service life; but this fabricated structure still adopts whole cam disc to cooperate with the curve rail; and employing steel material; exist cam Heavy Weight, the rotary inertia identical with monoblock type cast iron structure big equally, loom starts difficulty, shuts down slow, problems such as power consumption is big, percent defective is high, manufacturing cost height.
[summary of the invention]
Purpose of the present invention is exactly to propose a kind of plastic circular loom cam in order to solve problems of the prior art, can weight reduction, improve start and shutdown speed, and cut down the consumption of energy and cost.
For achieving the above object, patent of the present invention has proposed a kind of plastic circular loom cam, comprises cam chair and is installed in cam ring on the cam chair, and described cam ring is assembled by 2 or above arc-shaped guide plate, has cam path on the outer peripheral face of described arc-shaped guide plate.
As preferably, described cam chair comprise central part and by central part to extraradial at least 2 spokes.
As preferably, described at least 2 spokes evenly distribute along periphery.
As preferably, described cam chair also comprises wheel rim, and described wheel rim is the center of circle with the central part, and the end of spoke is connected on the wheel rim.
As preferably, described wheel rim is circular.
As preferably, described cam ring is assembled by six identical arc-shaped guide plates.
As preferably, adopt securing member to connect between the described polylith arc-shaped guide plate.
As preferably, adopt bonding agent to connect between the described polylith arc-shaped guide plate.
The beneficial effect of patent of the present invention: the present invention adopts the pin-connected panel cam structure; be that cam constitutes with cam chair and cam ring; and cam ring adopts the polylith arc-shaped guide plate assembled; the light high performance materials such as making arc-shaped guide plate employing engineering plastics of dying becomes possibility; guaranteeing under the constant prerequisite of cam intensity and ABRASION RESISTANCE; alleviate the weight and the rotary inertia of cam greatly, improve the startup and shutdown performance of loom, reach the effect that reduces braiding percent defective, saves energy and reduce cost.

Fig. 2 is Figure 1A-A cutaway view;
Fig. 3 is the structural representation of the embodiment one of plastic circular loom cam convexity wheel seat of the present invention;
Fig. 4 is the structural representation of the embodiment two of plastic circular loom cam convexity wheel seat of the present invention;

[specific embodiment]
Consult Fig. 1,2, plastic circular loom cam comprises cam chair 1 and is installed in cam ring 2 on the cam chair 1, and described cam ring 2 is assembled by 2 or above arc-shaped guide plate 7, has cam path 3 on the outer peripheral face of described arc-shaped guide plate 7.Arc-shaped guide plate 7 general employing intensity and ABRASION RESISTANCE are good, and the material material lighter than steel.The general materials such as engineering plastics (as: nylon 66 etc.), plastics, aluminium that adopt can certainly adopt the good material of other intensity and ABRASION RESISTANCE.
Consult Fig. 3,4, cam chair 1 has two kinds of embodiment.A kind of be cam chair 1 comprise central part 4 and by central part 4 to extraradial spoke 5.Central part 4 is fulcrums of whole cam, plays a supportive role to extraradial spoke 5.Spoke 5 evenly distributes along periphery, and 5 at least 2 of spokes can be 3,4,5,6 etc.Adopt 3 formation 3 point-supported effective, and also simple in structure, cost is low.Another kind of embodiment is to increase wheel rim 6 on the basis of embodiment one again, and wheel rim 6 is the center of circle with central part 4, and the end of spoke 5 is connected on the wheel rim 6.Wheel rim 6 adopts circular usually.For guaranteeing support strength, cam chair 1 the best is to adopt steel, cast iron or the high material of other cost performance.
Consult Fig. 5, cam ring 2 is assembled by six identical arc-shaped guide plates 7.Adopt assembled structure, making plastic or other material make cam becomes possibility, and reduces the manufacturing expense of mould of plastics and the manufacturing cost of cam greatly.If adopt the cam ring 2 of the plastic material of an integral body, difficulty of processing is very high so, and the manufacturing expense of mould of plastics is also quite expensive.If the quantity of arc-shaped guide plate 7 is too much certainly, can cause the structure of cam ring 2 more complicated, the processing that influences cam ring 2 is used.Therefore, take all factors into consideration difficulty of processing, cost and product quality problem, adopting six identical arc plastics guide plates 7 assembled is optimum structure.
Adopt securing member, bonding agent, welding or common the connection between the described polylith arc-shaped guide plate 7.Cam ring 2 usefulness securing members, bonding agent or be weldingly fixed on the end or wheel rim 6 of spoke 5 of cam chair 1.
The foregoing description is to explanation of the present invention, is not limitation of the invention, any scheme after the simple transformation of the present invention is all belonged to protection scope of the present invention.
