Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a water pump connecting rod structure for a water jet loom. Background Art

[0002] The water jet loom uses water as the weft insertion medium. The water jet generates frictional traction on the weft yarn, driving the weft yarn into the shed and interweaving with the warp yarn to form a fabric. The weft insertion system of the water jet loom includes a plunger pump with a one-way valve installed at the inlet and outlet ends, an inlet pipe connected to the inlet channel of the plunger pump, an outlet pipe connected to the outlet channel of the plunger pump, and a nozzle connected to the outlet pipe. The plunger pump relies on the reciprocating motion of the plunger in the cylinder body to change the volume of the sealed working chamber to achieve liquid suction and liquid pressure; it has the advantages of high rated pressure, compact structure, high efficiency and convenient flow adjustment. CN208933591U discloses a double-spring weft insertion water pump for a water jet loom. The water pump is connected to a power connecting rod through a connecting plate and a joint. The movement of the power connecting rod acts on the water pump, so that the water pump sprays water. However, in the prior art, vibrations are generated during the operation of the power connecting rod, and the vibrations are also transmitted to the water pump along the connecting plate and the joint, reducing the service life of the water pump. The utility model provides a connecting rod structure for a water jet loom water pump, and provides a connecting rod with a vibration reduction effect, which can reduce the influence of vibration on the water pump and increase the service life of the water pump.

[0015] In order to more clearly illustrate the technical solution of the utility model, the utility model is further described below in conjunction with the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the utility model. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on this drawing and embodiment, which all belong to the protection scope of the utility model.

[0016] according to Figure 1-3 As shown, a water pump connecting rod structure of a water jet loom includes a joint 1 and a connecting rod 2. The joint 1 is an annular structure. A weight reduction groove 3 is provided on the inner wall of the joint 1. A cavity 4 is provided in the connecting rod 2. The cavity 4 is filled with shock-absorbing material. A sealing member is provided at the bottom of the connecting rod 2.

[0017] In the above specific embodiment, by providing a weight-reducing groove 3 on the inner wall of the joint 1, the mass of the joint 1 can be reduced, thereby reducing the impact of mass and inertia and playing a shock-absorbing role. At the same time, filling the cavity 4 with shock-absorbing material further enhances the shock-absorbing effect of the connecting rod, which can reduce the impact of vibration on the water pump and increase the service life of the water pump.

[0018] The weight-reducing groove 3 is an arc-shaped structure, and a plurality of weight-reducing grooves 3 are evenly distributed circumferentially with the axis of the joint 1 as the center. By providing a plurality of weight-reducing grooves 3, the weight of the joint 1 is effectively reduced.

[0019] The joint 1 and the connecting rod 2 are an integrally forged structure. Compared with the prior art in which the joint 1 and the connecting rod 2 are welded or injection molded, the connecting rod formed integrally by forging has stronger tensile strength and yield strength.

[0020] A countersunk hole is provided on the side wall of the joint 1, and a countersunk bolt 5 is provided in the countersunk hole. The countersunk bolt 5 abuts against the bearing in the joint 1. The joint 1 is connected to the rotating shaft on the connecting plate through the bearing. By providing the countersunk bolt 5, the bearing can be fixed.

[0021] The sealing member includes a sealing protrusion 6 on the inner wall of the cavity 4 of the connecting rod 2, and a sealing bolt 7 is threadedly connected to the sealing protrusion 6 to fix a sealing ring 8 on the sealing protrusion 6. The weight-reducing material is a mixture of shock-absorbing oil and magnesium powder. After the mixture of shock-absorbing oil and magnesium powder is filled into the cavity 4, the sealing bolt 7 is connected to the sealing protrusion 6, and the sealing ring 8 plays a sealing role to prevent the contents in the cavity 4 from flowing out. By filling the mixture of shock-absorbing oil and magnesium powder, a shock-absorbing effect can be further played to reduce the impact of vibration on the water pump.
