Description

Technical Field

[0001] The invention relates to an inverted-axis lever-type opening and closing device, belonging to the technical field of textile machinery. Background Art

[0002] The conventional sectional warping machine inverted shaft engaging tooth snapping opening and closing device is as follows Figure 1 As shown, the coupling plate 1 is installed on the output shaft of the reducer 9 and can slide on the shaft. The front connecting shaft 2 is installed on the fixed seat 10. The coupling plate 1 and the front connecting shaft 2 adopt a coupling tooth method. The coupling plate is meshed with the front connecting shaft. The opening and closing cylinder 6 is connected to the fork 3 through the connecting plate 5.

[0003] This snapping device is driven by the snapping cylinder 6 to drive the shift fork 3 to do reciprocating motion. The shift fork 3 is equipped with a guide wheel 4, which is placed in the guide groove of the joint plate 1 and contacts the two sides of the groove. When the shift fork 3 moves, the guide wheel 4 can drive the joint plate 1 to move together to achieve the snapping action. Since the snapping cylinder 6 and the reducer 9 are installed on the same side of the wall panel 11, the position of the cylinder is limited by the mounting flange of the reducer. Since the diameter of the reducer mounting flange is large, the position of the cylinder is far away from the joint plate, and the thrust point of the cylinder on the shift fork is far away from the joint plate. When the shaft is reversed, the joint plate meshes with the front connecting shaft. After the shift fork is subjected to force, it is easy to deflect and deform with the cylinder piston rod as the fulcrum, causing the joint plate to retreat, and the meshing surface between the joint plate and the front connecting shaft is reduced or even disengaged. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an inverted-axis lever-type opening and closing device for the above-mentioned prior art. The lever-type structure can perfectly solve the problem that since the opening and closing cylinder is located far away from the coupling plate, the shift fork is easily deflected and deformed with the cylinder piston rod as the fulcrum after being subjected to force, causing the coupling plate to retreat, and the meshing surface between the coupling plate and the front connecting shaft is reduced or even disengaged.

[0005] The technical solution adopted by the present invention to solve the above-mentioned problem is: an inverted axis lever type opening and closing device, which includes a fixed seat and a wall panel, the fixed seat is provided with a front connecting shaft, the wall panel is provided with a reducer, the output shaft of the reducer is provided with a coupling plate, the coupling plate can slide back and forth on the output shaft of the reducer, and the front connecting shaft is engaged with the coupling plate; a fork support and a cylinder mounting seat are provided on the wall panel, a fork is hingedly provided on the fork support, and an opening and closing cylinder is hingedly provided on the cylinder mounting seat, the piston rod end of the opening and closing cylinder is connected to the upper end of the fork, and the lower end of the fork is connected to the coupling plate.

[0006] Optionally, a first engaging tooth is disposed at the rear end of the front connecting shaft, and a second engaging tooth is disposed at the front end of the engaging disk, and the first engaging tooth and the second engaging tooth are meshed with each other.

[0007] Optionally, an annular groove is provided on the coupling plate, and left and right guide wheels are provided at the lower end of the shift fork, and the left and right guide wheels at the lower end of the shift fork are clamped in the annular groove.

[0008] Optionally, a cylinder joint is provided at the piston rod end of the opening and closing cylinder, and the cylinder joint is hinged to the upper end of the shift fork through a cylinder joint pin.

[0009] Optionally, the shift fork includes a shift fork connecting rod, and a shift fork head is provided at the lower end of the shift fork connecting rod.

[0010] Optionally, a bayonet is provided at the lower end of the shift fork connecting rod, and the shift fork head is clamped in the bayonet.

[0011] Optionally, the fork head includes two left and right forks, and the left and right guide wheels are respectively arranged on the inner sides of the left and right fork ends.

[0012] Optionally, the left and right guide wheels are arranged at an angle of °.

[0013] Optionally, the fork support is arranged between the joining plate and the opening and closing cylinder and is closer to the joining plate.

[0014] Optionally, the opening and closing cylinder adopts a cylinder with a locked rear cover.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] 1. The present invention uses the shift fork device as a lever, the guide wheel at one end of the shift fork device contacts the joint plate, and the other end is hinged to the joint of the piston rod of the opening and closing cylinder. The fulcrum of the lever is placed between the joint plate and the opening and closing cylinder, as close to the joint plate as possible. According to the principle of the lever, the product of the force on both sides of the lever fulcrum and the force arm is equal. According to this characteristic, the farther the opening and closing cylinder is from the joint plate, the greater the pressure of the shift fork device on the joint plate is. Therefore, under the premise of not changing the thrust of the opening and closing cylinder, the lever structure can perfectly solve the problem that the shift fork is easily deflected and deformed with the cylinder piston rod as the fulcrum after being stressed, which causes the joint plate to retreat, and the meshing surface of the joint plate and the front connecting shaft is reduced or even disengaged.

[0017] 2. The opening and closing cylinder of the present invention adopts a rear cover with a lock type. When the piston rod of this cylinder is fully retracted, the mechanical locking device takes effect and locks the cylinder piston rod in this position. This can effectively prevent the cylinder from accidentally running out of air and losing thrust during reverse shaft operation, causing the coupling plate to retreat.
