[0002] There are buffer devices in textile machinery and equipment. For example, the ground warp back beam and wool warp back beam mechanisms in towel looms. At present, the ground warp back beam mechanism mostly uses spring-type buffer structures, and the wool warp back beam mechanism mostly uses elastic steel plate-type buffer structures. The working principles of the two structures are basically the same. The purpose is to play a buffering and protective role when the ground warp yarn and wool warp yarn are transported during weaving on the loom, to prevent the yarn from breaking due to excessive tension changes during the warp feeding process.

DETAILED DESCRIPTION

[0021] The following is a detailed description of an airbag type cushioning device of the utility model with reference to the accompanying drawings.

[0022] See also Figure 1-5 The utility model provides a technical solution: an airbag type buffer device, comprising a support beam 1, a support plate 2, a baffle 3, a yarn guide plate 4, an elastic steel plate structure, an airbag structure and an air circuit device; the air circuit device is connected to the airbag structure, the airbag structure is fixed on the support beam 1, the elastic steel plate structure is connected to the support plate 2, the baffle 3 and the yarn guide plate 4 are connected to the support plate 2, the support plate 2 is connected to the support beam 1, and the support beam 1 is connected to the loom. The baffles 3 are respectively fixed at both ends of the support plate 2, one at each end, to prevent the elastic steel plate 6 from moving left and right when working. The airbag structure includes an airbag tube 8, an airbag support plate 7, an airbag plug 9, a screw plug 23, and a long bolt 10. The airbag tube 8 is placed on the airbag support plate 7. Airbag plugs 9 are respectively provided at both ends of the airbag tube. The airbag plug 9 at the exhaust end of the airbag tube 8 is provided with a screw plug 23 for exhaust, and this screw plug 23 is installed on the airbag plug 9 at the exhaust end to exhaust when the air pressure in the airbag tube 8 is too high. The long bolt 10 passes through the airbag support plate 7 and is connected to the airbag tube 8 by a nut. The hole on the airbag tube constrains the position of the airbag tube 8 to prevent the airbag tube 8 from moving left and right when working. The airbag support plate 7 is connected to the support beam 1, and a rubber sheet Ⅰ7-1 is pasted on one end of the airbag support plate 7.

[0023] like Figure 2 , Figure 3As shown, the airbag plug 9 is composed of a top plate 24, a rubber sleeve 25, a locking nut 26 and a vent bolt 27. The rubber sleeve 25 is arranged between the top plate 24 and the locking nut 26. Through holes are respectively arranged at the center of the top plate 24 and the rubber sleeve 25. A threaded hole is arranged at the center of the locking nut 26. The vent bolt 27 passes through the top plate 24 and the rubber sleeve 25 in sequence and is threadedly connected with the locking nut 26. When the thread on the vent bolt 27 rotates more toward the locking nut 26, the rubber sleeve 25 will be squeezed by the top plate 24 and the locking nut 26, the axial direction of the rubber sleeve 25 will become smaller and the radial direction will become larger, so that the outer diameter surface of the rubber sleeve 25 will fit tightly to the inner diameter of the airbag tube 8, playing a role of sealing and preventing air leakage.

[0024] The elastic steel plate structure includes an elastic steel plate 6 and a support plate 5. The support plate 5 is connected to the support plate 2. The elastic steel plate 6 is in contact with the support plate 5. A rubber plate II 6-1 is attached to one end of the elastic steel plate 6.

[0025] The gas circuit device includes a gas source 11, a quick-connect connector I 12, a pressure regulating valve 14, a quick-connect connector II 13, a quick-connect connector III 15, a quick-connect connector IV 16, a quick-connect connector V 17, a quick-connect connector VI 18 and a pressure gauge seat 19. The quick-connect connector I 12 is installed on the gas source 11, and the quick-connect connector II 13, the quick-connect connector III 15 and the quick-connect connector IV 16 are respectively connected to the pressure regulating valve 14. The quick-connect connector I 12 and the quick-connect connector II 13 are connected through the air pipe I 20. The quick connector IV16 and the quick connector V17 are connected through the trachea II21, the quick connector III15 and the quick connector VI18 are connected through the trachea III22, the quick connector V17 is connected to the airbag plug 9 in the airbag structure, and the quick connector VI18 is connected to the pressure gauge seat 19. The pressure in the airbag tube 8 is adjusted by the pressure regulating valve 14, and the adjusted pressure can be measured by inserting a pressure gauge into the pressure gauge seat 19.

[0026] When the loom is working, the yarn is subjected to tension during transportation, and the tension will act on the elastic steel plate 6. At the same time, the elastic steel plate 6 will squeeze the airbag tube 8. The airbag tube 8 is squeezed and deformed under the action of the tension. At the same time, the elastic steel plate 6 will swing in the direction of yarn transportation with the contact point with the support plate 5 as the fulcrum. When the yarn tension becomes smaller, the elastic steel plate 6 will rebound due to the reverse force of the airbag tube 8. At the same time, the elastic steel plate 6 will swing in the opposite direction of yarn transportation with the contact point with the support plate 5 as the fulcrum, thereby tightening the yarn and increasing the yarn tension, and so on.
