Description

Technical Field

[0001] The utility model relates to the technical field of roving frames, in particular to a thread supply device for a roving frame. Background Art

[0002] A roving frame is a spinning machine that turns fiber strips into roving. Roving frames are divided into wing-spindle roving frames and twist-twist roving frames according to the twisting mechanism. The wing-spindle roving frame continuously applies twist to the yarn strips by the rotation of the spindle wings to produce twisted roving. The twist-twist roving frame clamps and twists the yarn strips with a pair of twisting leather plates, forming a false twist with alternating positive and reverse twist directions on the yarn strips to produce untwist roving.

[0003] Most existing roving frame thread feeding devices have complex structures. When threading, some parts of the mechanism need to be disassembled, the steps are complicated, and it is not easy to clean. Utility Model Content

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a roving machine wire feeding device, comprising a support plate, a plurality of wire guides are arranged at the top edge of the support plate, a base is arranged at the bottom end of the support plate, a placement base is inserted at the top end of the base at the front end of the support plate, a plurality of coarse fiber placement tubes are placed on the top end of the placement base, two support rods are arranged at the top end of the base on both sides of the support plate, fixed blocks are arranged at the top edges of the two support rods near the support plate, a central axis is arranged between the two fixed blocks, a plurality of rollers are equidistantly arranged on the outer surface of the central axis, support blocks are arranged at the top ends of the two fixed blocks, a cross bar is arranged between the two support blocks, and a plurality of positioning wheels are arranged on the outer surface of the cross bar.

[0006] Preferably, each of the rollers, positioning wheels and wire guides are vertically distributed. When feeding fibers, the fibers twisted into threads pass through the wire guides from bottom to top, and then pass between the rollers and positioning wheels. The positioning wheels press the top of the thick fiber lines for positioning.

[0007] Preferably, an extension frame is provided on one side of the two support blocks, and an electric push rod is provided at the bottom end of the two extension frames. The bottom end of the electric push rod is installed on the top end of the support rod. The two electric push rods push the support blocks to perform linear movement up and down through the extension frame to facilitate online operation and cleaning.

[0008] Preferably, a frame is provided at the top of the placement base, and the coarse fiber placement cylinder is limited by the frame to facilitate the placement of materials.

[0009] Preferably, a positioning card plate is provided at the top of the base on one side of the placing base, and fixing holes are provided at the tops of the placing base and the base near the positioning card plate. When installing the placing base, one side of the placing base is pushed to contact the positioning card plate so that the fixing holes opened at the tops of the placing base and the base coincide with each other, and then the column is inserted into the fixing hole to fix the placing base.

[0010] Preferably, two long grooves are provided at the top of the base below the placing base, so that the placing base can be snapped onto the top of the base, thereby ensuring that the placing base will not shake or shift when supplying wires.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The roving frame wire feeding device uses a wire guide, a roller and a positioning wheel. When feeding the wire, the twisted fiber passes through the wire guide from bottom to top, and then two electric push rods are started to push the support block up through the extension frame to move the positioning wheel upward away from the roller. The wire passes through between the roller and the positioning wheel, and then the two electric push rods are started to pull down the support block through the extension frame to lower the positioning wheel, and the top of the thick fiber wire is pressed to position it, and one end of the wire is connected to the spindle wing. The structure is simple and convenient for threading. When feeding the wire, the positioning wheel and the roller are used together to press the wire tightly to avoid the fiber from curling up and causing entanglement. The positioning wheel can be adjusted in height to facilitate cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figures 1 to 3 As shown, the present application includes a support plate 1, a plurality of wire guides 15 are arranged at the top edge of the support plate 1, and holes are opened through the top of the wire guides 15 so that the twisted fibers can pass through the wire guides 15 from bottom to top. A base 3 is arranged at the bottom end of the support plate 1, and a placement base 4 is inserted at the top of the base 3 at the front end of the support plate 1. A plurality of coarse fiber placement cylinders 6 are placed at the top of the placement base 4. The coarse fiber placement cylinders 6 can be used to place twisted fibers. The staff can arrange the coarse fiber placement cylinders 6 above the placement base 4 in advance, and can directly replace the placement base 4 when refilling, thereby improving efficiency. Two support rods are arranged at the top of the bases 3 on both sides of the support plate 1. 2. A fixing block 11 is provided at the top edge of the two support rods 2 near the support plate 1, a central axis 7 is provided between the two fixing blocks 11, a plurality of rollers 9 are equidistantly arranged on the outer surface of the central axis 7, and the plurality of rollers 9 are located above the corresponding guides 15, so that the linear fibers can be transported above the rollers 9, a supporting block 14 is provided at the top of the two fixing blocks 11, a cross bar 8 is provided between the two supporting blocks 14, a plurality of positioning wheels 10 are provided on the outer surface of the cross bar 8, and the plurality of positioning wheels 10 are located above the corresponding rollers 9 and match the surfaces of the rollers 9 to press the linear fibers to avoid the phenomenon of the linear fibers being lifted up during the supply of the wires.

[0019] Specifically, each roller 9, positioning wheel 10 and wire guide 15 are vertically distributed. When feeding fibers, the twisted fibers pass through the wire guide 15 from bottom to top, and then pass between the roller 9 and the positioning wheel 10. The positioning wheel 10 presses the top of the thick fiber line for positioning.

[0020] Furthermore, an extension frame 13 is provided on one side of the two support blocks 14, and an electric push rod 12 is provided at the bottom end of the two extension frames 13.
