Description

Technical Field

[0001] The utility model relates to a switch device, in particular to a switch device for a suction cylinder of a roving machine. Background Art

[0002] With the improvement of roving machine textile technology, the length of the roving machine body increases. The roving machine will inevitably produce waste cotton during the spinning process, which requires the suction cylinder to generate negative pressure on the waste cotton, collect the waste cotton and make the waste cotton leave the roving machine. However, as the length of the roving machine body increases, the length of the suction cylinder also increases, which will lead to the waste cotton being not cleanly handled due to the large distance and low negative pressure intensity. Utility Model Content

[0003] The utility model aims to provide a switch device for the suction tube of a roving machine, so as to solve the problem that the waste cotton cannot be cleanly processed due to the excessive length of the suction tube.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A double-duct suction cylinder switch device for a roving machine comprises a double-duct cylinder, wherein the double-duct cylinder has a first air inlet and a second air inlet; comprises a cylinder, a rotating shaft and a baffle, wherein the baffle is rotatably connected between the first air inlet and the second air inlet, the baffle is connected to the rotating shaft, the rotating shaft is connected to the double-duct cylinder via a fixed plate, the cylinder is hinged to the rotating shaft via a rotating bracket; the cylinder realizes the opening and closing of the air inlet by driving the baffle.

[0006] Furthermore, a slot is formed at one end of the rotating shaft, and the rotating bracket is connected to the rotating shaft via the slot; a bearing is provided on the rotating shaft, a bearing seat is sleeved on the outer side of the bearing, and the bearing seat is connected to the fixed plate via a connecting bracket.

[0007] Furthermore, the connecting bracket is provided with a rotating pin seat, and the rotating pin seat is hinged to the fixed end of the cylinder.

[0008] Furthermore, the rotating bracket includes a first hinged portion and a second hinged portion, the first hinged portion is hinged to the telescopic end of the cylinder, and the second hinged portion is fixed in the slot.

[0009] Furthermore, the baffle includes a first baffle and a second baffle, which are connected and formed by a connecting portion, and a bolt hole is provided on the connecting portion, and the first baffle is at a right angle to the second baffle; the first baffle is adapted to the first air inlet, and the second baffle is adapted to the second air inlet.

[0010] Furthermore, the baffle is connected to the rotating shaft by bolts.

[0011] Furthermore, the fixing plate is provided with fixing holes for connecting the double-duct air cylinder.

[0012] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0013] The utility model connects the baffle plate through a rotating assembly, and controls the rotation of the baffle plate through the rotating assembly to block the redundant air ducts, so that the negative pressure is concentrated in a single air duct to increase the pressure. The rotating assembly causes the baffle plate to first block the first air duct, thereby increasing the negative pressure strength of the second air duct in disguise, so that the waste cotton at the corresponding position of the second air duct is cleaned up. The rotating assembly causes the baffle plate to rotate to block the second air duct, opens the first air duct, and cleans up the waste cotton at the corresponding position of the first air duct, and finally cleans up the waste cotton generated in the spinning process of the roving frame. The utility model achieves the purpose of cleaning up waste cotton at a large distance, and has a simple structure and high efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] like Figures 1 to 4As shown, a double-duct suction cylinder switch device for a roving machine includes a double-duct air cylinder 1, the double-duct air cylinder 1 has a first air inlet and a second air inlet; includes a cylinder 2, a rotating shaft 3 and a baffle 4, the baffle 4 is rotatably connected between the first air inlet and the second air inlet, the baffle 4 is connected to the rotating shaft 3, the rotating shaft 3 is connected to the double-duct air cylinder 1 through a fixed plate 5, the cylinder 2 is hinged to the rotating shaft 3 through a rotating bracket 6; the cylinder 2 realizes the opening and closing of the air inlet by driving the baffle 4. The baffle 4 includes a first stopper 11 and a second stopper 12, the first stopper 11 and the second stopper 12 are connected and formed by a connecting portion 13, a bolt hole 14 is provided on the connecting portion 13, the first stopper 11 and the second stopper 12 are at right angles; the first stopper 11 is adapted to the first air inlet, and the second stopper 12 is adapted to the second air inlet. When the cylinder 2 extends, the cylinder 2 drives the baffle 4 to rotate through the rotating shaft 3, so that the first stop 11 blocks the first air inlet. At this time, the first air inlet is closed and the second air inlet is opened; the wind pressure acts completely on the second air inlet, and the waste cotton corresponding to the second air inlet is cleaned up. After the opening time is reached, the cylinder 2 is retracted, and the cylinder 2 drives the baffle 4 to rotate through the rotating shaft 3, so that the second stop 12 blocks the second air inlet, and the first air inlet is opened at the same time. At this time, the first air inlet is opened and the second air inlet is closed, so that the wind pressure acts completely on the first air inlet, and the waste cotton corresponding to the first air inlet is cleaned up. At this point, the cleaning of the roving frame is completed, which is simple and efficient.

[0019] A slot 15 is provided at one end of the rotating shaft 3, and the rotating bracket 6 is connected to the rotating shaft 3 through the slot 15; a bearing 16 is provided on the rotating shaft 3, and a bearing seat 17 is sleeved on the outer side of the bearing 16, and the bearing seat 17 is connected to the fixed plate 5 through a connecting bracket 18. When the rotating shaft 3 rotates, the bearing 16 reduces the friction force for the rotating shaft 3 to rotate, so that the rotation of the rotating shaft 3 is more flexible. The connecting bracket 18 is provided with a rotating pin seat 19, and the rotating pin seat 19 is hinged to the fixed end of the cylinder 2. The rotating pin seat 19 can limit the swing of the cylinder 2 during operation and realize the positioning of the cylinder 2.

[0020] The rotating bracket 6 includes a first hinge part 21 and a second hinge part 22. The first hinge part 21 is hinged to the telescopic end of the cylinder 2. When the cylinder 2 is telescopic, the first hinge part 21 and the cylinder 2 will rotate relative to each other, making the movement of the cylinder 2 more stable. The second hinge part 22 is fixed in the slot 15. The second hinge part 22 is locked in the slot 15 by bolts and nuts to achieve a stable connection between the rotating shaft and the rotating bracket 6.

[0021] The baffle plate 4 is bolted to the rotating shaft 3. The baffle plate 4 is fixedly connected to the rotating shaft 3, so that the rotating shaft 3 can drive the baffle plate 4 to rotate when rotating, and prevent the rotating shaft 3 and the baffle plate 4 from rotating relative to each other. The fixing plate 5 is provided with a fixing hole for connecting the double air duct 1.
