Description

Technical Field

[0001] This utility model relates to the field of weaving machine technology, and in particular to a warp and weft separator for a weaving machine. Background Technology

[0002] A warp and weft separator on a loom typically refers to a component used to separate and manage the warp threads (longitudinal yarns) during the weaving process. This component is crucial for ensuring fabric quality and smooth weaving. During weaving, the warp threads are fixed to the loom and need to maintain a certain spacing and parallelism. The separator helps maintain the position of these warp threads, preventing them from tangling or becoming misaligned. Separators are usually installed on the reed or other relevant locations on the loom. As the weft threads (transverse yarns) pass through the warp threads via the shuttle, the separator helps ensure that the weft threads are correctly interlaced between the warp threads. The design and material of the separator can vary depending on the type of loom, the type of fabric, and the specific application requirements. For example, some separators may be made of metal to provide strength and durability; while in other cases, materials such as plastic may be used to reduce noise or weight.

[0003] On the same loom, the two warp and weft separators are usually connected by ropes that pass around pulleys. Since there is no limiting device between the ropes and the pulleys, the ropes can easily slip out of the pulleys, making it impossible for the two warp and weft separators to work in coordination and affecting the weaving process. Utility Model Content

[0004] The main purpose of this utility model is to provide a warp and weft separator for a weaving machine to solve the problem in related technologies where there is no limiting device between the yarn and the pulley, and the yarn easily slips out of the pulley.

[0007] The driving unit includes a first driving group and a second driving group. The first driving group is used to drive the outer partition plate to move up and down, and the second driving group is used to drive the inner partition plate to move up and down.

[0008] The limiting part has two parts, which are located above the left and right ends of the dividing piece part, respectively. The limiting part includes a pulley part and a limiting group. The rope passes around the pulley part to connect the two dividing pieces. The limiting group is located above the pulley part. When the rope passes around the pulley part, the limiting group slides towards the pulley part and presses the rope between the pulley part and the limiting group.

[0009] Furthermore, the support includes a base plate, a warp beam, and two supports. The warp beam is fixedly mounted on the front end of the upper surface of the base plate, and the two supports are fixedly mounted on the rear end of the upper surface of the base plate, located at both ends of the partition plate.

[0010] Furthermore, the dividing plate includes a dividing group and a transmission group. The dividing group includes a support frame, several dividing strips and several dividing holes, and the transmission group includes a connecting rod and two pull rings.

[0011] Furthermore, the dividing strips are all fixed inside the support frame, the dividing holes are all located in the middle of the dividing strips, the connecting rods are fixed at the bottom of the support frame, and the two pull rings are all fixed at the top two ends of the support frame.

[0018] Compared with the prior art, this utility model has the following beneficial effects: the collar slides downward along the vertical axis, bringing the limiting block into the groove and pressing down the rope. The shape of the limiting block is the same as the shape of the groove. By setting the limiting block, the rope is pressed into the groove, so that the rope can slide around the pulley and prevent the rope from falling out of the groove, which would cause the two separating pieces to be unable to move in coordination and affect the progress of the textile work. A blocking ring is provided at the bottom of the vertical axis to limit the descent height of the collar, so that there is a small distance between the limiting block and the groove. The limiting block can both press down the rope and ensure that the rope can slide normally. Attached Figure Description

[0030] Please see Figures 1 to 4 This embodiment provides a warp and weft yarn separator for a weaving machine, including: a support part 1, which provides support for a drive part 2, a separator part 3 and a limiting part 5;

[0031] The dividing plate 3 has two pieces, an inner and an outer piece, which are connected by a top cord 4. The dividing plate 3 is used to divide the warp thread passing through it into upper and lower parts.

[0033] There are two limiting parts 5, located above the left and right ends of the dividing plate part 3 respectively. Each limiting part 5 includes a pulley part and a limiting group. The rope 4 passes around the pulley part to connect the two dividing plate parts 3. The limiting group is located above the pulley part. When the rope 4 passes around the pulley part, the limiting group slides towards the pulley part, pressing the rope 4 between the pulley part and the limiting group.

[0034] The support part 1 includes a base plate 11, a warp beam 12 and two supports 13. The warp beam 12 is fixedly installed on the front end of the upper surface of the base plate 11, and the two supports 13 are fixedly installed on the rear end of the upper surface of the base plate 11 and located at both ends of the partition plate part 3.

[0035] The dividing section 3 includes a dividing group and a transmission group. The dividing group includes a support frame 31, a number of dividing strips 32 and a number of dividing holes 33. The transmission group includes a connecting rod 34 and two pull rings 35.

[0036] The dividing strips 32 are all fixed inside the support frame 31, the dividing holes 33 are all located in the middle of the dividing strips 32, the connecting rods 34 are fixed at the bottom of the support frame 31, and the two pull rings 35 are fixed at both ends of the top of the support frame 31.

[0037] The drive unit 2 also includes a left support block 21, a right support block 22, a support rod 23 and a transmission rod 26. The first drive group includes a first connecting plate 24 and a first eccentric wheel 25, and the second drive group includes a second connecting plate 27 and a second eccentric wheel 28.

[0038] The left support block 21 is fixedly installed on the left side of the upper surface of the base plate 11, and the right support block 22 is fixedly installed on the right side of the upper surface of the base plate 11. The right support block 22 is equipped with a power source. In this embodiment, a motor is preferred as the power source for easy operation and is used to drive the transmission rod 26 to rotate.

[0039] One end of the support rod 23 is fixedly connected to the left support block 21, and the other end is fixedly connected to the right support block 22. One end of the transmission rod 26 is rotatably connected to the left support block 21, and the other end is rotatably connected to the right support block 22.

[0040] The first connecting plate 24 and the second connecting plate 27 are both rotatably sleeved on the outer ring of the support rod 23. The connection parts of the first connecting plate 24 and the second connecting plate 27 with the support rod 23 are provided with torsion springs. The first eccentric wheel 25 and the second eccentric wheel 28 are both fixedly sleeved on the outer ring of the transmission rod 26. The front end of the first connecting plate 24 is fixedly connected to the bottom of the connecting rod 34 of the outer partition plate 3. The front end of the second connecting plate 27 is fixedly connected to the bottom of the connecting rod 34 of the inner partition plate 3.

[0041] The pulley section includes a pulley 51, a groove 52, and a horizontal shaft 53. The limiting group includes two collars 54, a limiting block 55, and two vertical shaft groups. The vertical shaft group includes a vertical shaft 56, a slot 57, and a limiting rod 58, which presses the rope 4 between the two to prevent it from falling off. The bottom of the vertical shaft 56 is provided with a blocking ring to limit the descent height of the collars 54, so that the limiting block 55 and the groove 52 are kept at a distance. The limiting block 55 can both press down on the rope 4 and ensure that the rope 4 can slide normally.

[0042] The groove 52 is located in the middle of the pulley 51. The horizontal shaft 53 passes through the pulley 51 and is rotatably connected to the pulley 51. The vertical shaft 56 is fixedly installed at both ends of the horizontal shaft 53 and is fixedly connected to the bracket 13. The collars 54 are slidably installed on the outer ring of the vertical shaft 56. The limiting block 55 is fixedly installed between the two collars 54. The slot 57 is oppositely installed on the inner side of the vertical shaft 56. The limiting rod 58 is rotatably installed at the lower end of the slot 57. The bottom of the limiting rod 58 is provided with a torsion spring. When there is no external force, the torsion spring pushes the limiting rod 58 out of the slot 57. It is not necessary to squeeze the rope 4 to lift the collar 54 away from the pulley 51.

[0043] Tie one end of the rope 4 to the pull ring 35 at the top of the outer partition plate 3, pass it around the groove 52, and then tie it to the pull ring 35 at the same top of the inner partition plate 3. Then connect the inner and outer partition plates 3 in the same way. Push the two limiting rods 58 upwards respectively, so that the limiting rods 58 rotate into the slots 57. The collar 54 slides downwards along the vertical axis 56, bringing the limiting block 55 into the groove 52, pressing down the rope 4, and preventing the rope 4 from falling out of the groove 52, which would cause the two partition plates 3 to be unable to move in coordination.

[0044] The first warp thread, used for textile underwear fabric, is passed sequentially through the dividing hole 33 of the outer dividing plate 3 and the gap between the two dividing strips 32 of the inner dividing plate 3, and the end of the warp thread is fixed to the warp frame 12. The second warp thread is then passed sequentially through the gap between the two dividing strips 32 of the outer dividing plate 3 and the dividing hole 33 of the inner dividing plate 3, and the end of the warp thread is fixed to the warp frame 12. This process is repeated until all warp threads are passed through the dividing holes 33 and fixed to the warp frame 12. The motor inside the right support block 22 is then started, driving the transmission rod 26 to rotate. The transmission rod 26 drives the first eccentric wheel 25 and the second eccentric wheel 28 to rotate simultaneously. Rotating downwards, the first connecting plate 24 is pressed downwards and rotated. This causes the outer dividing plate 3 to move downwards via the connecting rod 34. The outer dividing plate 3 pulls the warp threads passing through it downwards. The second eccentric wheel 28 rotates upwards, and the second connecting plate 27 springs up under the action of the torsion spring at its end. This causes the inner dividing plate 3 to move upwards via the connecting rod 34. The inner dividing plate 3 pulls the warp threads passing through it upwards, and the two warp threads separate. The weft threads pass through the middle. This operation is repeated to complete the weaving process. The warp ropes 4 at the top of the two dividing plates 3 on the inner and outer sides are connected to maintain the coordinated movement of one descending and the other rising, so that there is always a gap for the warp threads to pass through in the two parts.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
