Description

Technical Field

[0001] The present invention relates to the technical field of medical paper inspection equipment, and in particular to a yarn support assembly on medical paper production equipment. Background Art

[0002] Yarn supports are generally used in the textile industry. In the textile industry, yarn is the raw material and basis of its production. In textile work, the processed yarn needs to be wound on the yarn bobbin and then the textiles are produced.

[0003] Chinese patent publication number CN205046295U discloses a yarn supply frame for a circular knitting machine, comprising a base frame, several bobbin holders, and several yarn guide nozzles. The bobbin holders are mounted on the right column of the base frame, and the yarn guide nozzles are mounted on the left column of the base frame. A universal head is provided at the tail of the yarn guide nozzle. The universal head includes an outer spherical shell and an inner spherical shell. The outer spherical shell is rotatably mounted in the inner hole of the left column via a horizontally arranged rotating shaft, and the inner spherical shell is rotatably mounted in the outer spherical shell via a vertically arranged rotating shaft. During use, yarn is pulled from the yarn bobbin, passed through the yarn guide nozzles and the universal head, and input into the circular knitting machine for processing.

[0004] However, in actual processing, since the yarn guide nozzle and universal head only guide the yarn and cannot increase the tension of the yarn, the yarn becomes loose after being pulled out from the yarn bobbin, affecting the weaving of the circular knitting machine.

[0005] Chinese patent publication number CN207738941U discloses a yarn stand comprising a base frame including a plurality of crossbars, on which a plurality of bobbin holders are mounted, and a tensioning device corresponding to each bobbin holder. The tensioning device comprises a fixing assembly mounted on the crossbars and a yarn guide mechanism mounted on the fixing assembly. The yarn guide mechanism comprises a yarn guide plate, a first yarn guide block having a first yarn guide hole fixedly connected to one end of the yarn guide plate near the bobbin holder; a second yarn guide block having a second yarn guide hole fixedly connected to the other end of the yarn guide plate; and a yarn guide post disposed in the middle of the yarn guide plate. The yarn guide post ensures that the yarn input to the circular knitting machine is first wound around the yarn guide post, thereby increasing the pulling force of the yarn, thereby increasing the yarn tension, preventing yarn slack, and improving the knitting quality of the circular knitting machine. The tensioning device in this yarn stand has a complex structure, resulting in unstable yarn routing after output and prone to yarn breakage. Furthermore, the stand occupies a large area.

[0006] The applicant applied for Chinese patent publication number CN207738941U in 2021, which discloses a surgical paper towel production equipment. The equipment includes a yarn mesh forming unit, a yarn mesh gluing unit, a composite forming unit of the yarn mesh and the upper and lower surgical paper towels, an unwinding unit for the upper and lower surgical paper towels, and a rewinding unit for the composite surgical paper towels, which are arranged on a frame in sequence. Each of the units is electrically connected to an industrial computer. The equipment first weaves yarn into a grid-like yarn mesh, then applies glue on both sides of the yarn mesh, and then clamps the yarn mesh between the upper and lower surgical paper towels. A pair of surgical paper towel composite rollers are then used to heat and pressurize the upper surgical paper towel, the yarn mesh, and the lower surgical paper towel to form a medical multi-layer absorbent fiber reinforced material. This equipment features a high degree of automation and is capable of continuous, mass-produced surgical tissues. It ensures that the yarn mesh of the surgical tissues is firmly bonded to the upper and lower layers of paper, with a uniform yarn mesh and a specific wrinkled, foamed effect achieved through bidirectional shrinkage. The patent application also describes a yarn spindle support, which is used to house the spindles used to weave the yarn mesh. Located at one end of the surgical tissue production equipment, the yarn bobbins are arranged in rows, each containing several bobbins. This bobbin support method requires a large floor space, resulting in unstable yarn output, prone to yarn breakage, and easily disorganized yarn on the bobbins. The yarn is fed from the bobbins and fed between two layers of paper via a guide comb plate, where warp and weft yarns form a reinforcing yarn mesh between the two layers of paper. Summary of the Invention

[0007] The purpose of the present invention is to solve the above technical problems and to provide a yarn support assembly for medical paper production equipment which has a simple structure, is easy to process and manufacture, has a small bracket footprint, has a stable and uniform yarn output speed, is not prone to yarn breakage, and is easy to operate for yarn bobbin replacement.

[0008] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a yarn support assembly on medical paper production equipment, characterized in that the yarn support assembly includes a frame composed of columns, crossbeams and longitudinal beams, and a yarn bobbin positioning rod is provided on the crossbeam. The crossbeam and the yarn bobbin positioning rod constitute a yarn bobbin support. The axis extension lines of the yarn bobbin positioning rods on two parallel crossbeams on the frame intersect with the axis of the yarn guide rod, and the outer wall of the yarn guide rod is tangentially arranged to the axis of the yarn bobbin. The two ends of the yarn guide rod are respectively connected to the longitudinal beams on the frame. A tensioner mounting rod arranged in the same direction as the crossbeam is also provided between the columns. The tensioner mounting rod is connected to the longitudinal beam through a pin support, and the tensioner mounting rod is installed with a yarn tension adjuster. The extended axis of the yarn bobbin positioning rod on two parallel beams on the frame intersects with the axis of the yarn guide rod, and the outer wall of the yarn guide rod is arranged tangent to the axis of the yarn bobbin. This structural design can ensure that the yarn output on the yarn bobbin can be gathered on the outer wall of the yarn guide rod from beginning to end, so that the yarn output from the yarn bobbin will not be disordered from beginning to end, thereby greatly reducing yarn breakage. The tension of the yarn output can be adjusted by setting the yarn tension regulator.

[0009] In order to facilitate the loading and unloading between the crossbeam and the longitudinal beam, and to facilitate the longitudinal sliding adjustment of the crossbeam on the longitudinal beam, the preferred technical solution is that the longitudinal beam is Sliding connection between the shaped or H-shaped sleeve and the longitudinal beam.

[0010] In order to facilitate the quick installation and removal between the crossbeam and the longitudinal beam, the crossbeam is installed at an eight-shaped angle. The preferred technical solution is that the crossbeam is installed at an eight-shaped angle. A slot at the end of the crossbeam is provided on one side of the vertical short side of the shaped or H-shaped sleeve, and two adjacent slots are arranged in an eight-shaped shape. The angle between the two slots is the same as the angle between the axes of the two relative yarn bobbin positioning rods. The two ends of the crossbeam on the frame are respectively inserted into the slots of the sleeves arranged on the longitudinal beams on both sides of the frame.

[0011] In order to reduce the overall weight of the bracket and improve the strength and rigidity of the bracket, a further preferred technical solution is that the columns, crossbeams, longitudinal beams and bobbin positioning rods are all hollow tubes.

[0012] In order to facilitate the quick installation of the yarn holder, improve the stability of the yarn holder, and reduce the labor intensity of the installation operation, a further preferred technical solution is that the yarn guide rod and the longitudinal beam are connected through a pin support, and the longitudinal beam and the column are connected through an angle code or by welding.

[0013] To facilitate control of the tension of the yarn output from the bobbin and to further increase the strength of the yarn support, a further preferred technical solution is that the tension adjuster includes a channel steel frame, within which are disposed a plurality of transversely arranged yarn support rods. A baffle is disposed on one side of the channel steel frame, and through holes for yarn passage are provided on the baffle and the bottom surface of the channel steel frame. At least one counterweight ring is disposed between the plurality of yarn support rods, and a clamping ring connected to the tensioner mounting rod is disposed on the outer side of the channel steel frame. In actual use, different numbers of counterweight rings are suspended to adjust the yarn tension.

[0014] In order to enable the yarn bobbins to be arranged neatly on the yarn holder, and at the same time to enable the yarn to be output from the yarn holder neatly and orderly, and to enable the yarn bobbin positioning rod to be firmly and stably fixed on the crossbeam, a further preferred technical solution is that a plurality of yarn bobbin positioning rods are provided on each of the crossbeams, and the positions of the plurality of yarn bobbin positioning rods on two adjacent crossbeams are arranged corresponding to each other, and a positioning platform connected to the yarn bobbin positioning rod is provided at the connection between the yarn bobbin positioning rod and the crossbeam.

[0015] In order to facilitate the processing and manufacturing of the bracket, facilitate loading and unloading, facilitate the adjustment of the bracket, and facilitate the operator to easily replace the yarn bobbin, a further preferred technical solution is that the crossbeam located between the two longitudinal beams at the same height between the columns, and the yarn bobbin positioning rod arranged on the crossbeam and the sleeves at both ends of the yarn bobbin positioning rod connected to the longitudinal beam together constitute a yarn bobbin support sub-unit.

[0016] In order to facilitate the processing and manufacturing of the bracket, facilitate loading and unloading, facilitate the adjustment of the bracket, and facilitate the operator to easily replace the yarn bobbin, a further preferred technical solution is that a yarn bobbin support unit row composed of multiple layers of yarn bobbin support sub-units is arranged from top to bottom between the four columns, and a yarn bobbin support unit row composed of several yarn bobbin support unit rows is arranged between several columns. Multiple yarn bobbin support unit rows can constitute the overall structure of the yarn support frame.

[0017] In order to ensure that the yarns output from the yarn bobbins on the yarn support can be output in an orderly manner, a further preferred technical solution is that a plurality of porous wire passing plates for guiding the yarns to pass through are provided on the columns of the yarn support frame.

[0018] Compared with the prior art, the present invention has the following advantages: the yarn support assembly on the medical paper production equipment has a simple structure, is easy to manufacture, occupies a small area, has a stable and uniform yarn output linear speed, is not prone to yarn breakage, and facilitates yarn bobbin replacement. Existing yarn supports only consider the problem of supporting the yarn bobbin, but do not consider how to ensure that the linear speed of the yarn output from the bobbin remains constant. If the yarn on the bobbin is randomly output from any direction of the bobbin, the linear speed of the yarn output will be fast or slow, which can easily cause yarn breakage and uneven tightness of the woven yarn mesh. In the technical solution of the present application, the axis extension line of the yarn bobbin positioning rod on two parallel beams arranged on the frame intersects with the axis of the yarn guide rod, and the outer wall of the yarn guide rod is arranged tangent to the axis of the yarn bobbin. This structural design can ensure that the yarn output on the yarn bobbin can be converged on the outer wall of the yarn guide rod from beginning to end, so that the linear speed of the yarn output on the yarn bobbin can always remain unchanged. In this way, the yarn output from the yarn bobbin will not be disordered from beginning to end, and there will be no problem of yarn output being loose and tight. This can greatly reduce the yarn breakage situation, and can also make the tightness of the woven yarn mesh consistent. The tension of the yarn output can be adjusted by setting the yarn tension regulator. BRIEF DESCRIPTION OF THE DRAWINGS
