Description

Technical Field

[0001] This utility model relates to the field of shuttle rod technology, specifically to a mixed-weft shuttle rod. Background Technology

[0002] The weft insertion shuttle is a crucial component in looms. It guides the weft yarn into the shed via a specific mechanism, allowing the warp and weft yarns to interweave into fabric. Different types of looms use different weft insertion mechanisms, such as rapier weft insertion mechanisms and air-jet weft insertion mechanisms; therefore, the weft insertion shuttle is an essential part of the loom.

[0003] A search revealed a prior art square mixed-weft shuttle rod (publication number: CN207391674U), which describes that "the square mixed-weft shuttle rod body has an elongated opening, and connecting blocks are welded to the inner walls of both sides of the elongated opening. Reinforcing ribs are welded between the two connecting blocks. A connector is fixedly installed at one end of the square mixed-weft shuttle rod body. An opening is opened on one side of the connector, and one end of the square mixed-weft shuttle rod body extends into the opening of the connector. Two bolts are fixedly installed between one end of the square mixed-weft shuttle rod body and the connector." This mixed-weft shuttle rod, through the combination of the connector and the square mixed-weft shuttle rod body, allows for direct replacement of the connector when the bearing of the connector is damaged, without discarding the entire square mixed-weft shuttle rod body, thus reducing economic losses. The method of welding reinforcing ribs to the middle part of the square mixed-weft shuttle rod body can reduce the weight of the square mixed-weft shuttle rod body and increase the toughness of the entire square mixed-weft shuttle rod body. However, the mixed-weft shuttle rod body and the connector are fixedly connected by two sets of bolts, which makes the assembly and disassembly process of the mixed-weft shuttle rod body and the connector not convenient. At the same time, there are two obvious long strip cavities between the mixed-weft shuttle rod body and the reinforcing ribs, which leads to the structural strength of the mixed-weft shuttle rod body body relative to the long strip cavities, which easily increases the probability of deformation and damage to the mixed-weft shuttle rod body body. Furthermore, the reinforcing ribs are welded to the mixed-weft shuttle rod body body, so when the mixed-weft shuttle rod body body is damaged, the reinforcing ribs must also be discarded, thereby reducing the replacement cost of the mixed-weft shuttle rod body body.

[0004] To overcome the shortcomings of the existing technology, a mixed-weft shuttle rod is provided to solve the problems mentioned in the background art.

[0005] To achieve the above object, a mixed weft return swing rod is provided, including: a mixed weft return swing rod main body, the mixed weft return swing rod main body is fixedly connected to a connector through a main bolt, and an installation hole is opened at one end of the mixed weft return swing rod main body away from the connector.

Mounting seats are symmetrically connected to both sides of the weight reduction groove. Both ends of the reinforcing plate are fixedly connected to the fixing plates through auxiliary bolts. Support plates are correspondingly connected to the positions of the mounting seats on both sides of the reinforcing plate.

Positioning grooves are correspondingly opened at the positions of the inner cavity of the connector opposite to the positioning plates. At the same time, the sizes of the positioning grooves are adapted to the sizes of the positioning plates.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the cooperation of the positioning plate and the positioning groove, only one set of main bolts is needed to achieve a stable fixed connection between the main body of the weft-loop shuttle arm and the connector, improving the ease of assembly and disassembly between the main body and the connector.

Simultaneously, when the main body of the weft-loop shuttle arm is damaged, the reinforcing plate and support plate can be quickly disassembled for secondary recycling, reducing the need for replacement of the main body and improving resource recycling rate.

[0018] Reference Figures 1 to 4 As shown, this utility model provides a mixed-weft shuttle rocker arm, including: a mixed-weft shuttle rocker arm body 2, a connector 1 fixedly connected to the mixed-weft shuttle rocker arm body 2 by a main bolt, and an installation hole 10 opened at the end of the mixed-weft shuttle rocker arm body 2 away from the connector 1. A weight-reducing groove 6 is opened inside the mixed-weft shuttle rocker arm body 2, and a fixing plate 4 is symmetrically connected to the lower side of both ends of the weight-reducing groove 6. Mounting seats 8 are symmetrically connected to both sides of the weight-reducing groove 6, and the fixing plate 4 is fixedly connected to both ends of the reinforcing plate 5 by auxiliary bolts. Support plates 7 are connected to both sides of the reinforcing plate 5 at positions corresponding to the mounting seats 8. Limiting plates 9 are symmetrically connected to both sides of the inner cavity of the mounting seats 8. Limiting grooves are opened on the surface of the support plate 7 at positions corresponding to the limiting plates 9. Positioning plates 3 are symmetrically connected to the end of the mixed-weft shuttle rocker arm body 2 near the connector 1, and positioning grooves are opened on the surface of the inner cavity of the connector 1 at positions corresponding to the positioning plates 3.

[0019] In this embodiment, when installing the mixed-weft shuttle arm, first align the positioning plate 3 with the positioning groove in the inner cavity of the connector 1, then embed the mixed-weft shuttle arm body 2 and the positioning plate 3 into the inner cavity of the connector 1 and the positioning groove, respectively. Then, thread the main bolt through the through hole in the mixed-weft shuttle arm body 2 to the threaded hole in the inner cavity of the connector 1, thereby completing the fixed connection between the mixed-weft shuttle arm body 2 and the connector 1, which facilitates the efficiency of loading and unloading. When the mixed-weft shuttle arm body 2 is deformed and damaged while the reinforcing component is intact, first remove the mixed-weft shuttle arm body 2 from the connector 1, then remove the secondary bolt, and release the fixed connection between the fixing plate 4 and the reinforcing plate 5. The reinforcing plate 5 and the support plate 7 can then be easily removed from the weight reduction groove 6, allowing the reinforcing component composed of the reinforcing plate 5 and the support plate 7 to be recycled and reused, thereby effectively reducing the cost of replacing the mixed-weft shuttle arm and reducing resource waste.

[0020] As a preferred embodiment, the weight-reducing groove 6 opened in the mixed weft shuttle swing arm body 2 has a rectangular structure, and the two sets of fixing plates 4 fixedly connected to the two end faces of the weight-reducing groove 6 have a square structure, and the lower surface of the fixing plate 4 and the lower surface of the mixed weft shuttle swing arm body 2 are in the same horizontal plane.

[0021] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The weight reduction groove 6 can effectively reduce the overall weight of the mixed weft shuttle arm body 2. At the same time, the fixing plate 4 and the mixed weft shuttle arm body 2 are made of one piece using a molding process.

[0022] In a preferred embodiment, three sets of mounting seats 8 are fixedly connected at equal intervals along the length direction on both sides of the weight reduction groove 6, and all six sets of mounting seats 8 have a U-shaped structure, and the two sets of limiting plates 9 fixedly connected in the middle of the inner cavity of the mounting seat 8 have a rectangular structure.

[0024] As a preferred embodiment, the reinforcing plate 5 has a long strip structure, and both ends of the reinforcing plate 5 have a convex structure. The size of the grooves at both ends of the reinforcing plate 5 is adapted to the size of the fixing plate 4. At the same time, through holes are opened at the positions of the screw holes at both ends of the reinforcing plate 5 relative to the fixing plate 4.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3, the structural settings at both ends of the reinforcing plate 5 enable the reinforcing plate 5 not to specifically distinguish between the front and back during installation, improving the convenience during installation. At the same time, the reinforcing plate 5 is fixedly connected to the fixing plate 4 through auxiliary bolts, and then the reinforcing plate 5 can assist in enhancing the overall structural strength of the mixed - weft return - shuttle swing rod body 2.

[0026] As a preferred embodiment, the six groups of support plates 7 fixedly connected to both sides of the reinforcing plate 5 are all in a long - strip structure, and the combination of the reinforcing plate 5 and the support plates 7 forms a cross - shaped structure, and the end of the support plate 7 far from the reinforcing plate 5 abuts against the inner side of the weight - reducing groove 6.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 , the setting of the support plate 7 can effectively increase the number of support points inside the weight - reducing groove 6, and then can assist in enhancing the overall structural strength of the mixed - weft return - shuttle swing rod body 2, reducing the probability of deformation and damage of the mixed - weft return - shuttle swing rod.

[0028] As a preferred embodiment, the two groups of limit grooves opened at one end of the support plate 7 close to the mounting seat 8 are both in a rectangular structure, and the sizes of the limit grooves and the limit plates 9 are adapted to each other, and at the same time, the sizes of the support plate 7 and the inner cavity of the mounting seat 8 are adapted to each other.

[0029] In this embodiment, as Figure 2 and Figure 4 , the limit plates 9 and the support plates 7 are respectively adapted to the sizes of the limit grooves and the inner cavity of the mounting seat 8, so that the connection stability between the support plate 7 and the mounting seat 8 can be effectively enhanced. And the cooperation between the limit plates 9 and the limit grooves enables the support plate 7 to provide good force support for the mixed - weft return - shuttle swing rod body 2 in the horizontal direction, thereby reducing the probability of deformation and damage of the mixed - weft return - shuttle swing rod.

[0030] As a preferred embodiment, two groups of positioning plates 3 are respectively fixedly connected to the upper and lower surfaces of the mixed - weft return - shuttle swing rod body 2 near the练级头 (it seems there is a wrong word here, assuming it should be a correct component name, let's just keep it as is for now) end. The four groups of positioning plates 3 are all in a rectangular structure, and positioning grooves are correspondingly opened at the positions of the inner cavity of the connecting head 1 relative to the positioning plates 3, and the sizes of the positioning grooves and the positioning plates 3 are adapted to each other.
