Description

Technical Field

[0001] The invention relates to the technical field of circular looms, and in particular to a wire feeding frame of a circular loom. Background Art

[0002] A circular loom refers to industrial equipment used to weave tubular cloth. There are many spindles on the warp frame of the circular loom. A specified range of warp yarns are used according to the width of the woven cloth and the width of the flat yarn. Before the warp yarn enters the circular loom, the warp yarn is cross-opened by the warp yarn frame, and the weft yarn shuttle moves in a circular motion in the cross-opening to pass through the warp yarn and weave into a tubular cloth. The circular loom is mainly composed of a frame, a transmission system, a warp yarn system, etc. Among them, the wire feed frame, also known as the warp yarn frame, is a device on the circular loom for supporting and transmitting yarns. It is usually composed of a steel pipe or steel frame as the skeleton, and wire feed rods arranged on the skeleton to ensure that the yarn can be supplied to the weaving area of ​​the circular loom in an orderly and stable manner.

[0003] In the prior art, when the circular loom is working, the wire feed frame stably delivers the yarn to the weaving area through the wire feed rod. At the same time, the wire feed rod has elasticity and can cooperate with the shaking of the weaving end to adjust the tightness of the yarn and provide tension to ensure that the yarn maintains appropriate tension during the transmission process to avoid weaving problems caused by yarn relaxation or excessive tension. However, there are multiple wire feed rods, and the tension is increased by their own deformation, resulting in inconsistent movement amplitudes of multiple wire feed rods, and the uneven tension of the yarn leads to wrinkles on the surface of the woven product. Summary of the invention

[0004] The present invention aims to provide a circular loom wire feeding frame to solve the problem in the prior art that the swing amplitudes of multiple wire feeding rods are inconsistent, the tension of the yarns is not uniform, and the surface of the woven product has wrinkles.

[0005] In order to solve the above problems, the present invention provides the following technical solutions:

[0006] A wire feeding frame for a circular loom comprises a frame, on which an annular skeleton is fixedly provided, and the skeleton is connected to a plurality of rotating handles which rotate coaxially and evenly in a circumferential direction, and each rotating handle is fixedly provided with a plurality of wire feeding rods at even intervals; and further comprises a connecting ring which abuts against the bottoms of the plurality of rotating handles, and the frame is fixedly provided with a cylinder which drives the connecting ring to move up and down.

[0007] Working principle and beneficial effects of the present invention:

[0008] In the technical solution, since the rotating handle and the frame are rotatably connected, and the connecting ring is in abutment with the bottom of all the rotating handles, the connecting ring is driven up and down by the cylinder, and all the rotating handles are pushed up and down by the connecting ring to rotate, and the rotating handle drives all the wire feeding rods to swing up and down. Since the amplitude of the up and down swing of all the wire feeding rods is the same, compared with the prior art, the wire feeding rods do not rely on their own deformation to swing, thereby making the yarn tension uniform, ensuring that there will be no wrinkles on the surface of the woven product, thereby improving the quality of the woven product.

[0009] Optimally, a ring portion is provided at the top of each wire feeding rod. When the circular loom is working, multiple yarns are respectively introduced into the ring portion at the top of each wire feeding rod, and the other end of the yarn is introduced into the weaving end of the circular loom, and the ring portion plays a role in pulling the yarn to shake and adjust its tension.

[0010] Preferably, the angle between adjacent rotating handles in the circumferential direction is 30 degrees. With this arrangement, the number of rotating handles can be 12, thereby facilitating the increase of the weaving speed.

[0011] Optimally, the interior of the connecting ring is a hollow structure, and the connecting ring is coaxially rotatably connected to a rotating ring. A motor for driving the rotating ring to rotate is fixedly provided inside the connecting ring. The connecting ring is provided with a sliding opening along the circumferential direction opposite to the corresponding rotating handle, and the sliding opening is vertically slidably connected to a push rod abutting the bottom of the rotating handle. The rotating ring is fixed with a pushing block for pushing the push rod to slide up and down, and the thickness of the pushing block gradually decreases along the circumferential direction of the rotating ring.

[0012] The rotating ring is driven by a motor to rotate, and the rotating ring drives the pushing block to rotate. The thickness change of the pushing block is utilized to change the upward squeezing amplitude of the pushing block on the push rod, thereby changing the height of the push rod outside the connecting ring. The push rod is used to support the rotating handle, and the rotating handle is movable, so as to adjust the height of the rotating rod at one end of the push rod. For example, this height is reduced, and then the inclination angle of all the wire feeding rods on the rotating handle is changed, so that the initial inclination angle becomes larger. When the connecting ring moves upward under the action of the cylinder, the connecting ring squeezes the rotating handle to rotate through the push rod. Due to the initial inclination angle of all the wire feeding rods on this rotating handle compared with all the wire feeding rods on other rotating handles, the tension degree of the yarn of all the wire feeding rods on this rotating handle is different from that of all the wire feeding rods on other rotating handles, thereby weaving products with pleats to meet the needs of special occasions.

[0013] Optimally, the number of the sliding openings is multiple or one. By changing the initial inclination angles of all the wire feeding rods on the multiple rotating handles, multiple pleated products with different spatial arrangements can be woven.

[0014] Optimally, a spring is fixedly arranged between the push rod and the sliding opening, and the spring is used to accelerate the descending speed of the push rod in the sliding opening.

[0015] Optimally, the push rod is close to the middle of the corresponding rotating handle. This optimization solution prevents the push rod from being disengaged during the process of lifting the rotating handle.

[0016] Optimally, the wire feeding rod has a certain curvature, which is conducive to the connection between the yarn and the woven cloth end. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following is further described in detail through specific implementation methods:

[0026] In the following statements, directional words such as "left", "right", "up", and "down" are all based on the directions shown in the diagram. In practice, if the corresponding structures are changed in the same direction based on the directions while keeping the relative positions unchanged, it will not affect the implementation of the plan.

[0028] Embodiment 1: A circular loom wire feeding frame, referring to Figure 1 , including a frame (not shown in the figure), the frame is fixed with an annular skeleton 1, the skeleton 1 is connected with 6 rotating handles 2 that rotate coaxially and evenly along the circumferential direction, each rotating handle 2 is fixed with 3 wire feeding rods 4 at even intervals; it also includes a connecting ring 5 that abuts against the bottom of the 6 rotating handles 2, and the frame is fixed with a cylinder 3 that drives the connecting ring 5 to move up and down.

[0029] like Figure 2 and Figure 3 As shown, in the present technical solution, since the rotating handle 2 and the skeleton 1 are rotatably connected, and the connecting ring 5 abuts against the bottom of all the rotating handles 2, the connecting ring 5 is driven to move up and down by the cylinder 3, and all the rotating handles 2 are pushed to rotate up and down by the connecting ring 5, and the rotating handle 2 drives all the wire feeding rods 4 to swing up and down. Since the amplitude of the up and down swinging of all the wire feeding rods 4 is the same, compared with the prior art, the wire feeding rods 4 do not rely on their own deformation to swing, thereby making the yarn tension uniform, ensuring that there will be no wrinkles on the surface of the woven product, and improving the quality of the woven product.

[0030] Embodiment 2: The difference from Embodiment 1 is: Figure 5 , Figure 4 and Figure 6 As shown, the interior of the connecting ring 5 is a hollow structure, and the connecting ring 5 is coaxially connected to the rotating ring 9. The connecting ring 5 is fixed with a motor 7 for driving the rotating ring 9 to rotate, that is, the bottom of the connecting ring 5 is coaxially fixed with a bevel gear 10, and the motor 7 drives a helical gear meshing with the bevel gear 10. The connecting ring 5 is provided with a sliding opening relative to the two rotating handles 2 along the circumferential direction, and the sliding opening is vertically slidably connected with a push rod 6 respectively abutting against the bottom of the two rotating handles 2, and the rotating ring 9 is fixed with a push block 8 for pushing the push rod 6 to slide up and down, as shown in FIG. Figure 8 As shown, the thickness of the push block 8 gradually decreases along the circumferential direction of the rotating ring 9.

[0031] like Figure 7 As shown, the rotating ring 9 is driven to rotate by the motor 7, and the rotating ring 9 drives the pushing block 8 to rotate. The thickness change of the pushing block 8 is utilized to change the upward squeezing amplitude of the pushing block 8 on the push rod 6, thereby changing the height of the push rod 6 outside the connecting ring 5. The push rod 6 is used to support the rotating handle 2, and the rotating handle 2 is movable, so as to adjust the height of the rotating rod at one end of the push rod 6, for example, to reduce this height, thereby changing the inclination angle of all the wire feeding rods 4 on the rotating handle 2, so that the initial inclination angle becomes larger. Then, when the connecting ring 5 moves upward under the action of the cylinder 3, the connecting ring 5 squeezes the rotating handle 2 to rotate through the push rod 6. Due to the initial inclination angle of all the wire feeding rods 4 on this rotating handle 2 compared with all the wire feeding rods 4 on other rotating handles 2, the tension degree of the yarn of all the wire feeding rods 4 on this rotating handle 2 is different from that of all the wire feeding rods 4 on other rotating handles 2, thereby weaving products with pleats to meet the needs of special occasions.

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art.
