Description

Pneumatic type spray air splicer

The utility model relates to a kind of bobbin winder and two-for-one twister of being applicable to coarse yarn, open-end spinning is spun pneumatic type air splicer with strand, particularly a kind ofly is used for the broken end that yarn or strand have certain hygroscopicity fibre and does not have the pneumatic type spray air splicer that knot is spliced.

The applicant in 1993 in first to file the patent No. be " pneumatic type water smoke air splicer " Chinese utility model patent of 93226360.7.This utility model constitutes by fixing a water mist device by screw on the pneumatic type air splicer, water mist device be include a water receiver, two check valves, cylinder, fluid cylinders in the type body and place cylinder respectively and fluid cylinder in gas piston and water piston.This utility model is tied the quality requirement that the quality of splicing all reaches knotless yarn, line to the nothing that coarse yarn, open-end spinning, strand etc. have certain hygroscopicity fibre.But structurally there is weak point in this utility model, influences its product quality, dependability and give to use and maintenance brings some inconvenience.For example, be connected with external plastic tube between fluid cylinder and the check valve, the flexible under pressure distortion of plastic tube influences stable water outlet; Air is difficult to drain fully in the fluid cylinder, influences the stability of water yield; The spring that the push rod of manipulation check valve is installed is understood malfunctioning and misoperation; When regulating because of no scale sign causes, the adjusting rod that regulating pondage is used feels unsure of; The finite capacity of water receiver can't strengthen moisture storage capacity when needed; Do not have water level stake on the water receiver, be difficult to observe the interior moisture storage capacity of water receiver etc.

This practical purpose is to provide a kind of improved pneumatic type spray air splicer, improves the quality of products, and improves the splicer dependability, is more convenient for using and maintaining.

In order to achieve the above object, the utility model adopts following technical proposals: the utility model is the same with prior art to be constituted by fixing a water mist device by screw on the pneumatic type air splicer, and water mist device is to comprise a water receiver, two check valves, cylinder, fluid cylinders in the type body and place cylinder respectively and gas piston and water piston that fluid cylinder is interior.It is characterized in that between check valve and the fluid cylinder with stomidium and channel connection under the water piston in the type body.So just removing in the prior art influences stable water outlet with external plastic tube connection, influences functional reliability and product quality.

The utility model can be equipped with the steam vent of band plug screw in upper end, water mist device side, so that can drain air in the fluid cylinder fully, improves job stability and product quality.The utility model also can be at the push rod lower end screw thread of the handling check valve stairstepping handle that spin, by handle pull down upside-down mounting again and fixed mandril, eliminate the misoperation that in the prior art spring is arranged and produce, improve functional reliability.The utility model can also have the water inlet of dress plug screw in the water receiver bottom, can be used for external standby water storage tank in case of necessity, to overcome the defective of water receiver finite capacity in the prior art.The utility model can be added with the scale sign to the adjusting rod of regulating pondage, and water receiver is equipped with water level stake, is more convenient for using.

The utility model compared with prior art, have following conspicuous advantage: the utility model has improved functional reliability and stability, thereby improves the quality of products, simultaneously easy to use and maintenance.

The drawing of accompanying drawing is described as follows:

Fig. 6 removes plug screw 35 and the part sectioned view that connects pipe 37 and pipe joint 36 among Fig. 1.

An optimum implementation of the present utility model is: referring to Fig. 1, theory structure of the present utility model is the same with ZL93226360.7 number Chinese utility model patent with operation principle: the handle 38 of opening two logical valves 4, from source of the gas 1 pressure is the upper arrival gas circuit 7 of the compressed air of 5.4-6.8kg/cm through valve 4, and be divided into three the tunnel then: the first via enters cylinder 5; The second the tunnel enters 3-position-3-way valve 3; Third Road enters the below of cylinder 11.First via gas makes the descent of piston in the cylinder 5, and it is descending to drive connector 2, and at the descending initial stage, promptly piston is in when upper, finishes yarn clipping, cuts action such as yarn.The second road gas enters the upper of valve 3 and is blocked at this moment.Descending when the continuation of cylinder 5 pistons, connector 2 takes valve 3 to meta, and the second road gas just flow to untwist air path 15, and the yarn tail is carried out untwisting.When cylinder 5 descent of pistons when the next, valve 3 also doubly takes to the next, then the second the tunnel enters twisting gas circuit 14, high velocity air produces swirling eddy through the twisting chamber, and the yarn cabrage after two sections untwistings is newly twisted into an one thread.In the whole process of cylinder 5 descent of pistons, the Third Road air-flow enters the below of cylinder 11, makes piston stroking upward, drives fluid cylinder 10 piston stroking upwards, check valve 12 sealings, check valve 13 is opened, in the water suction fluid cylinder 10 in the water receiver 9.In addition, the residual air below cylinder 5 pistons through gas circuit 6 from valve 4 emptyings.When cylinder 5 descent of pistons cause valve 3 impact valve 4 during to below, make valve 4 commutations, what this moment, compressed air can only be through valve 4 is the next, arrive gas circuit 6, be divided into two road gas, the first via makes piston stroking upward through the below that adjustable choke 8 enters cylinder 5, and another road enters the top of cylinder 11, make that piston commutation is descending, check valve 13 sealings, check valve 12 open, it is standby that water enters twisting gas circuit 14.When moving, standby water becomes molecule under the action of high-speed airflow of gas circuit next time, is vaporific with the yarn tail twisting of air-flow after to untwisting, and with gas slightly 7 residual air that link to each other through the next emptying of valve 4.

Referring to Fig. 2, Fig. 3, Fig. 4 and Fig. 5, this pneumatic type spraying splicer constitutes by fixing a water mist device 17 by screw on the pneumatic type air splicer 16, water mist device 17 be include a water receiver 9, two 12,13, fluid cylinders 10 of check valve in the type body 18 and place cylinder 11 respectively and fluid cylinder 10 in gas piston 19 and water piston 20.Be communicated with 20 times stomidiums 21 of water piston and passage 22,23,24 in the type body 18 between check valve 12 and the fluid cylinder 10.There is steam vent 25 upper end, water mist device 17 sides, and steam vent 25 is communicated with on same horizontal plane with passage 24, and steam vent has bleed screw 26 for 25 mouthfuls, unclamps 26 of plug screws and can be emptied completely the interior air of fluid cylinder.The push rod 28 lower end screw threads of the handling check valve 13 stairstepping handle 27 that spins.Handle 27 can screw off upside-down mounting then can be fixing to push rod 28.On the connection gas piston 19 that regulating pondage is used and the adjusting rod 30 of water piston 20 locking nut 31 is arranged, scale sign 32 is arranged on the locking nut 31, adjusting knob 33 is arranged at adjusting rod 30 tops, and there is pit look 34 on adjusting knob 33 tops.According to scale sign 32 and pit color dot 34.Quantitative regulating pondage, water level stake 29 is equipped with in water receiver 9 sides, can observe the moisture storage capacity of water receiver at any time.Water inlet is also arranged at water receiver 9 bottoms.Stop up by plug screw 35.Referring to Fig. 3 and Fig. 6, when needing, can dismantle plug screw 36 and connect pipe 37 and joint 36, pipe 37 external standby water storage tanks.
