[0013] The utility model discloses can reach following beneficial effect using it: the utility model simple and reasonable structure, convenient operation adopts pneumatic mode, and control is flexible, and cost is low. Greatly reduce the probability that the yarn hangs in the negative pressure channel, simultaneously reduce the frequency of manual intervention, guarantee the normal operation of twist joint trolley, improve production efficiency. BRIEF DESCRIPTION OF DRAWINGS
[0014] Fig. 1 It is the structure schematic diagram of the utility model.
[0015] Fig. 2 It is the structure schematic diagram of the utility model when the air supplement door 2 is closed. DETAILED DESCRIPTION
[0016] The specific embodiment of the utility model is described in detail below in combination with the drawings.
[0017] As Figs. 1-2 The utility model discloses a kind of air supplement door devices.
[0018] The air supplement door device described in the embodiment, including wallboard 1, the wallboard 1 is equipped with negative pressure port 4, it penetrates wallboard 1;Air supplement door 2 is equipped on the outside of negative pressure port 4, air supplement door 2 is the structure of one end big one end small, two ends are circular arc structure.Air supplement door 2 is rotatably arranged relative to wallboard 1, air supplement door 2 is equipped with power mechanism, for opening or closing air supplement door 2, air supplement door 2 is fixed on wallboard 1 in not being equipped with power mechanism (i.e. small end);Wallboard 1 is equipped with suction nozzle negative pressure passage 6 on the other side of air supplement door 2, and is connected with large and small suction nozzles, sealing gasket 5 is equipped between suction nozzle negative pressure passage 6 and wallboard 1 to seal.
[0019] Further, the wallboard 1 is equipped with first shaft 3 and second shaft 10, respectively for the fixation of air supplement door 2 and power mechanism, and is further limited by open blocking ring, while ensuring that air cylinder 9 and air supplement door 2 can be flexibly rotated on first shaft 3 and second shaft 10.The power mechanism of the embodiment is air cylinder 9.
[0020] Air supplement door 2 is equipped with protrusion 21 at small end, and is equipped with stepped shaft 22 at big end.Protrusion 21 is combined with first shaft 3, and sleeve is arranged between the two for positioning, and first shaft 3 penetrates protrusion 21 and is limited by open blocking ring.Second shaft 10 penetrates air cylinder 9 and is limited by open blocking ring, to fix air cylinder 9 on wallboard 1.
[0021] When air cylinder 9 is stretched, air supplement door 2 is pulled to rotate a certain angle, and closes negative pressure port 4.When air cylinder 9 is retracted, negative pressure port 4 is opened.
[0022] Further, the power mechanism and the air supplement door 2 are connected by a joint bearing 8. The inner spherical surface of the joint bearing 8 is sleeved on the stepped shaft 22 and is limited by an open retainer. The other end of the joint bearing 8 is connected with the air cylinder 9 for driving the air supplement door 2.
[0023] Further, the negative pressure port 4 is a circular hole.
