Description

Technical Field

[0001] The present application relates to the technical field of textile bobbin grasping mechanisms, and in particular to a textile bobbin pneumatic suction cup grasping mechanism. Background Art

[0002] The textile bobbin is a key equipment used in the spinning process, mainly used for the twisting and winding of yarn. It is not only a carrier for the twisting and winding of yarn, but also has an important impact on the quality of the yarn, such as uneven twist, hairiness, etc., and is also closely related to indicators such as end breakage per 1,000 spindles.

[0003] like Figure 1 As shown, the radius of the textile tube increases step by step from one end toward the other end. The textile tube is provided with a through hole, the axis of the textile tube is the same as the axis of the through hole, and the radius of the through hole increases step by step from this end toward the other end. The existing grasping mechanism uses two clamps to grasp the textile tube. Since the radius sizes at both ends of the textile tube are different, the difference in radius may cause uneven contact area between the clamp and the textile tube, resulting in the clamp failing to provide uniform clamping force during the clamping process, and the textile tube is easy to fall off the clamp. If the clamping force of the clamp on the textile tube is too large, the clamp may damage the outer surface of the textile tube, which needs to be improved. Utility Model Content

[0006] By adopting the above technical solution, the textile tube is placed on the placement plate, and the driving member drives one end of the rotating plate to rotate in the direction close to the placement plate, that is, the two baffles and the vacuum suction cup move in the direction close to the placement plate, so that the textile tube is located between the two baffles. The two baffles play a preliminary positioning role in the movement of the textile tube, so that the textile tube is located below the vacuum suction cup, which is convenient for the vacuum valve to control the vacuum suction cup to suck the textile tube and improve the stability of grabbing the textile tube. The driving member drives one end of the rotating plate to rotate in the direction away from the placement plate, that is, the textile tube moves in the direction away from the placement plate, which is convenient for moving the textile tube to other placement positions.

[0011] Optionally, the rotating plate is connected to a connecting plate, the connecting plate is located between the rotating plate and the baffles, the connecting plate is connected to one of the baffles via a locking piece, and the locking piece passes through the clearance hole.

[0012] By adopting the above technical solution, the locking piece passes through the clearance hole, and the locking piece restricts the movement of the vacuum suction cup, preventing the vacuum suction cup from aligning with the clearance hole, that is, preventing the vacuum suction cup from detaching from the baffle. When the baffle needs to be replaced, only the locking piece needs to be moved to separate the baffle from the connecting plate, which is convenient for

[0014] By adopting the above technical solution, the baffle plate can be separated from the connecting plate by simply rotating the first bolt to disengage the first threaded hole or the second threaded hole. The distance between the baffle plate and the connecting plate, that is, the distance between the vacuum suction cup and the connecting plate, can be adjusted by the first bolt, so that the device is suitable for textile bobbins of different sizes.

[0015] Optionally, the connecting plate is detachably connected to the rotating plate, the connecting plate and the rotating plate are connected by a second bolt, the rotating plate is provided with a third threaded hole for threadably mating with the second bolt, and the connecting plate is provided with a fourth threaded hole for threadably mating with the second bolt.

[0018] By adopting the above technical solution, the radius of the suction hole is larger than the radius of the connecting hole, so that the contact area between the vacuum suction cup and the textile tube is wider, the adsorption capacity of the vacuum suction cup is improved, the textile tube is more firmly adsorbed on the vacuum suction cup, and the stability of grabbing the textile tube is improved.

[0019] Optionally, the placement plate is connected to two limit plates, and the two baffles are located between the two limit plates.

[0020] By adopting the above technical solution, the textile tube rolls on the placement plate, and the two limiting plates guide and limit the rolling of the textile tube, thereby improving the rolling stability of the textile tube.

[0021] Optionally, the two limiting plates are connected to one side facing each other with a positioning plate.

The positioning plate positions the textile tube, making it easier for the vacuum suction cup to absorb the textile tube.

[0023] Optionally, the placement plate is provided with a hollow area, and the hollow area is located between the two limiting plates.

[0024] By adopting the above technical solution, the hollow area reduces the use of materials and saves material costs. The baffle can pass through the hollow area, providing space for the movement of the baffle, so that the vacuum suction cup can absorb the textile tube.

[0026] 1. The textile tube is placed on the placement plate, and the driving member drives one end of the rotating plate to rotate toward the placement plate, that is, the two baffles and the vacuum suction cup move toward the placement plate, so that the textile tube is located between the two baffles. The two baffles play a preliminary positioning role in the movement of the textile tube, so that the textile tube is located below the vacuum suction cup, which is convenient for the vacuum valve to control the vacuum suction cup to suck the textile tube, and improve the stability of grabbing the textile tube.

[0027] 2. The guide plate drives the textile tube to move toward a position close to the position between the two baffles, so that the textile tube moves to between the two baffles, which is convenient for positioning the textile tube, so that the textile tube is located below the vacuum suction cup, thereby improving the efficiency of the vacuum suction cup in sucking the textile tube.
