Description

Technical Field

[0001] This utility model belongs to the technical field of small bar wire packing machine heads, and particularly relates to a wire storage and feeding device for a small bar wire packing machine head. Background Technology

[0002] Traditional equipment adjusts the wire feeding tension using a mechanical screw, which is difficult to dynamically adjust and cannot adapt to the packaging needs of materials with different wire diameters. For example, when the wire diameter changes, the machine needs to be stopped and multiple adjusting bolts need to be manually adjusted, resulting in reduced production efficiency. Existing guide wheels are mostly fixed with a single bolt or welding, which can easily lead to bearing displacement or guide wheel axis misalignment due to vibration during long-term use.

[0003] Traditional wire storage devices rely on disassembling multiple parts to adjust the gap, requiring repeated adjustments to the relative positions of the guide wheel fixing plate and the cover plate. This operation is complex and makes it difficult to precisely control the uniformity of the gap, resulting in inconsistent wire storage tightness and affecting packaging quality.

[0004] Traditional equipment relies on manual intervention for wire guidance and position calibration, making online monitoring and adaptive correction difficult. When the wire wobbles, it can easily cause deviations in the kink angle or offsets in the cutting position of the cutter. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a wire storage and feeding device for a small bar wire packing machine head.

[0006] This small bar wire baling machine head uses a wire storage and feeding device, which includes: a wire feeding device for guiding and straightening the wire to be baled, and a wire storage device for temporarily storing excess wire to be baled during wire take-up.

[0007] The wire feeding device includes a spring screw, a screw positioning plate, a fixing pin, a spring, a wire guide wheel core, a rear guide block, a long fixing pin, a limiting plate, a center plate, a tensioning slider, a tensioning pin, a wire guide anti-collision block, a wire guide pin, a center guide block, and a guide block;

[0008] The wire storage device includes: a V-shaped wheel, a wire pressing bearing, a hinge, a lower guide wheel, a wire storage cover plate, a star-shaped handle, a lower guide wheel fixing plate A, a wire storage device base, a wire storage fixing pin, and a lower guide wheel fixing plate B.

[0009] Preferably, the wire feeding device contains:

[0010] A rear guide block is fixedly connected to the neutral plate by multiple long fixing pins. A middle guide block is also fixedly connected to the neutral plate by multiple fixing pins. The guide block is fixed to the neutral plate by fixing pins. The guide block has a sliding groove and a limiting plate that cooperates with the anti-collision block of the track to adjust the distance. The limiting plate is fixed behind the neutral plate. The anti-collision block of the track and the limiting plate are symmetrically arranged with respect to the neutral plate. There is also a compression spring. The compression spring is coaxially connected to a compression spring screw and a tensioning slider. The tensioning slider is installed in the sliding groove in the guide block. The compression spring screw is fixed to a screw positioning plate. The screw positioning plate is threadedly connected to the compression spring screw tensioning pin, which is installed at the bearing center of the track wheel core for fixing the bearing. The tensioning pin is fixed to the tensioning slider by a shaft clip.

[0011] As a preferred option:

[0012] The guide block is connected to multiple fixing pins by screws, and then fixed to the center plate by the fixing pins; the guide block is also equipped with a guide block cover plate;

[0013] The rear guide block is connected to multiple long fixing pins by screws; a rear guide cover plate is also installed on the rear guide block;

[0014] A center guide cover is also fixed to the center guide block by screws.

[0015] Preferably, the wire storage device contains:

[0016] The wire storage device base is fixed to the central plate by wire storage fixing pins. The wire storage device base is hinged to the wire storage cover plate, which can rotate around the hinge. A star-shaped handle is also fixed on the wire storage cover plate. The star-shaped handle is used to adjust the gap between the wire storage device base and the wire storage cover plate. The gap between the wire storage device base and the wire storage cover plate serves as the movement space for the material to be packaged. A lower guide wheel fixing plate A is fixed on the wire storage device base. A lower guide wheel is coaxially fixed on the lower guide wheel fixing plate A. The lower guide wheel is located on one side of the wire storage cover plate, and the lower guide wheel fixing plate A is located on one side of the wire storage device base. A lower guide wheel fixing plate B is also fixed on the wire storage device base. A V-shaped wheel and a wire pressing bearing are fixed on the lower guide wheel fixing plate B by bolts. The wire storage cover plate has holes corresponding to the positions of the V-shaped wheel and the wire pressing bearing. The V-shaped wheel and the wire pressing bearing pass through the lower guide wheel fixing plate B and the wire storage device base and extend into the corresponding holes in the wire storage cover plate. The wire pressing bearing is installed inside the V-shaped wheel.

[0017] The beneficial effects of this utility model are:

[0018] This invention features a spring screw that deforms a compression spring and a tensioning slider that cooperates with the spring screw. The tensioning slider can slide within a groove in a guide block. The width of the groove in the guide block is adjustable, allowing for adjustable tension when the material to be packaged passes through the groove. This enables dynamic adjustment and adaptability to the packaging needs of materials with different diameters, solving the problem of rigid adjustment in traditional screws. It can adapt to materials with different diameters and reduce downtime maintenance.

[0019] The V-shaped wheel and the wire pressing bearing adopt a double-hole limiting design, which can prevent the guide wheel from deflecting due to vibration, prevent wire scratches caused by bearing displacement, reduce equipment failure rate, and extend equipment life.

[0020] The wire storage cover is rotated and adjusted via a hinge and a star-shaped handle, avoiding the drawback of having to repeatedly disassemble the guide wheel fixing plate. Attached Figure Description
