Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a thread feeder for a loom. Background Art

[0002] The number of weft yarn rolls placed on the existing feeder rack is fixed. When larger-sized fabrics need to be produced, workers often need to replace different feeder racks to increase the number of weft yarn rolls placed on the feeder rack in order to adapt to production needs. This is time-consuming and labor-intensive, and increases the company's production costs. Through searching, it was found that although the existing technology with announcement number CN214736372U provides a solution, it has at least the following defects, namely: during the rotation of the weft yarn roll, the inner side of the weft yarn roll rubs against the connecting block, and the outer side of the weft yarn roll rubs against the stop bar; therefore, when the weft yarn roll is rotating, noise will be generated due to friction, and the rotational resistance of the weft yarn roll is large, and heat is easily generated at the contact position. Utility Model Content

[0003] The purpose of the present utility model is to provide a wire feeding stand for a loom to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wire feed frame for a loom, comprising a support frame, and the support frame is movably connected to a mounting frame; the mounting frame comprises a support plate, a weft yarn roll mounted on the support plate, and a rotating assembly mounted on the support plate; a connecting piece is provided through the weft yarn roll and then connected to the rotating assembly to rotatably mount the weft yarn roll on the support plate; the rotating assembly comprises a first bearing, a rotating ring is provided on the outer ring of the first bearing, and the inner ring of the first bearing is connected to a connecting pipe; the connecting piece contacts the inner wall surface of the weft yarn roll through a second bearing, and the outer wall surface of the connecting piece is threadedly connected to the inner wall surface of the connecting pipe.

[0005] As a preferred technical solution of the present invention: the connecting pipe passes through the first nut and the support plate and is connected to the second nut provided on the other side of the support plate.

[0006] As a preferred technical solution of the present invention: the support plate is connected to a first socket provided on the support frame via a first latch provided.

[0007] As a preferred technical solution of the present invention: the top of the support frame is movably connected to an expansion piece, and the expansion piece is connected to the mounting frame.

[0008] As a preferred technical solution of the present invention: the expansion piece includes a plate body, and the bottom surface of the plate body is connected to the second socket provided on the top surface of the support frame through a second latch provided thereon.

[0009] As a preferred technical solution of the present invention: a first fixing ear is further provided on one side of the plate body, and a bolt is passed through the first fixing ear to connect with a first screw hole provided on the support frame to fix the expansion member on the support frame.

[0010] As a preferred technical solution of the present invention: a third insertion hole, a second screw hole and a second fixing ear are further provided on a side of the plate body away from the second pin; wherein, the first fixing ear and the second fixing ear have the same structure, and the first fixing ear and the second fixing ear are both vertically arranged on the plate body.

[0011] By adopting the above technical solution, the present invention has the following beneficial effects: because the connecting member is rotatably connected to the weft roll via the second bearing, the resistance to the weft roll rotating in the axial direction of the connecting member is reduced. At the same time, when one side of the weft roll is in contact with the rotating ring, the rotation of the rotating ring on the first bearing can also reduce the resistance to the side of the weft roll during rotation. Based on this, using the above method, the second bearing can support the weft roll while also reducing the resistance to the weft roll during rotation. The use of the rotating ring in conjunction with the weft roll can further reduce the frictional resistance on the side of the weft roll, thereby ensuring stable and reliable rotation of the weft roll. Firstly, it prevents jitter, secondly reduces noise generated by the weft roll during rotation, and thirdly prevents the weft roll from heating during rotation. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] See also Figure 1-7 The utility model provides an embodiment: a wire feed frame for a loom, comprising a support frame 1, and the support frame 1 is movably connected to a mounting frame 3; the mounting frame 3 comprises a support plate 30 and a weft roll 32 mounted on the support plate 30, and a rotating assembly 34 mounted on the support plate 30; a connecting piece 33 is provided through the weft roll 32 and then connected to the rotating assembly 34, so that the weft roll 32 is rotatably mounted on the support plate 30; the rotating assembly 34 comprises a first bearing 38, a rotating ring 36 is provided on the outer ring of the first bearing 38, and the inner ring of the first bearing 38 is connected to a connecting pipe 37; the connecting piece 33 contacts the inner wall surface of the weft roll 32 through a second bearing 310, and the outer wall surface of the connecting piece 33 is threadedly connected to the inner wall surface of the connecting pipe 37.

[0022] In summary, since the connecting member 33 is rotationally connected to the weft roll 32 via the second bearing 310, the resistance to the weft roll 32 rotating in the axial direction of the connecting member 33 is reduced. At the same time, when one side of the weft roll 32 is in contact with the rotating ring 36, the rotation of the rotating ring 36 on the first bearing 38 can also reduce the resistance to the side of the weft roll 32 during rotation. Based on this, using the above-mentioned method, the second bearing 310 not only supports the weft roll 32 but also reduces the resistance to the weft roll 32 during rotation. The rotation of the rotating ring 36 and the weft roll 32 can also reduce the frictional resistance on the side of the weft roll 32, thereby ensuring stable and reliable rotation of the weft roll 32. Firstly, it prevents shaking, secondly reduces the noise generated by the rotation of the weft roll 32, and thirdly prevents the weft roll 32 from heating during rotation. In addition, since the second bearing 310 is inserted into the interior of the weft yarn roll 32 to support and fix the weft yarn roll 32, the outer end face of the connecting piece 33 does not need to fit into the outer side face of the weft yarn roll 32, thereby reducing the phenomenon of heat generated by friction when the weft yarn roll 32 rotates; wherein, the connecting piece 33 is cylindrical and inserted into the inner ring of the second bearing 310, and the inner ring is welded to the connecting piece 33 to avoid displacement of the second bearing 310 on the connecting piece 33.

[0023] Furthermore, since the connecting tube 37 passes through the first nut 35 and the support plate 30 and is connected to the second nut 39 provided on the other side of the support plate 30, the assembly and disassembly of the rotating assembly 34 and the support plate 30 is facilitated, and the user can easily select the number of rotating assemblies 34 to be installed according to needs. Specifically, after the first nut 35 is installed on the connecting tube 37, the other side of the connecting tube 37 passes through the support plate 30 and is connected to the second nut 39. As the two nuts move toward each other, the connecting tube 37 is securely fixed to the support plate 30. Conversely, the rotating assembly 34 can be disassembled by causing the two nuts to move away from each other.

[0024] In order to facilitate the expansion of the number of weft yarn rolls 32 that can be installed on the device, the support plate 30 is connected to the first socket 4 provided on the support frame 1 through a first pin 31. Specifically, when the first pin 31 passes through the first socket 4, it is also connected to the nut, thereby fixing the support plate 30 to the support frame 1; wherein, the first sockets 4 are grouped into three, and the connecting lines between any two centers of circles in each group are equal, thereby making the position of the support plate 30 stable and reliable after being connected to the support frame 1.

[0025] On the basis of the above solution, since the top of the support frame 1 is movably connected to the provided extension member 2, and the extension member 2 is connected to the mounting frame 3, the number of mounting frames 3 can be increased by mounting the mounting frames 3 on the extension member 2 and connecting the extension member 2 to the support frame 1, thereby allowing the device to increase or decrease the number of mounting frames 3 as needed.

[0026] Specifically, the expansion piece 2 includes a plate body 20, and the bottom surface of the plate body 20 is connected to the second socket 5 provided on the top surface of the support frame 1 through a second pin 23. Therefore, when the second pin 23 rotates in the second socket 5, the position of the mounting frame 3 during use can be adjusted.

[0027] Furthermore, since a first fixing ear 21 is provided on one side of the plate body 20, the expansion piece 2 is fixed to the support frame 1 by passing a bolt through the first fixing ear 21 and connecting it with the first screw hole 6 provided on the support frame 1. Therefore, by passing the bolt through the first fixing ear 21 and connecting it with the first screw hole 6, the expansion piece 2 and the support frame 1 can be positioned, thereby ensuring that the mounting frame 3 will not rotate along the central axis of the second pin 23 when in use.

[0028] Furthermore, since the side of the plate body 20 away from the second latch 23 is further provided with a third insertion hole 22, a second screw hole 24, and a second fixing ear 25, wherein the first fixing ear 21 and the second fixing ear 25 have the same structure and are both perpendicularly disposed on the plate body 20, it is convenient to assemble multiple expansion pieces 2 together. After assembly, bolts are passed through the second fixing ears 25 and then connected to the second screw holes 24, completing the positioning of the two expansion pieces 2 after assembly.

[0029] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
