Description

Technical Field

[0001] The utility model relates to the technical field of warp knitting machines, in particular to a bobbin fixing mechanism for a bobbin holder of a warp knitting machine. Background Art

[0002] A warp knitting machine is a professional device for producing knitted fabrics, which is widely used in multiple fields such as clothing, decoration, and industry. The characteristic of this kind of machine is that it can carry out knitting operations while the yarns are under tension, so as to produce fabrics with high stability and durability. With the development and technological progress of the textile industry, the performance requirements for warp knitting machines are also constantly improving. It is not only necessary to achieve high-efficiency production, but also to have flexibility and easy maintainability.

[0003] In a warp knitting machine, the bobbin holder is one of the key components. Its main function is to carry and guide the yarns into the knitting area. For example, in the Chinese utility model patent "A bobbin holder for a warp knitting machine" with the patent number CN214782460U, it includes two support columns. An installation plate is arranged between two adjacent support columns. A receiving groove is spacedly opened on one side wall of the installation plate. An installation rod for installing a bobbin is arranged inside the receiving groove. One end of the installation rod is provided with a connecting column, and the connecting column is fixedly arranged inside the receiving groove. The installation plate is provided with a card slot at the bottom of the receiving groove for the installation rod to rotate and snap into. When the installation rod rotates and snaps into the card slot, the installation rod is perpendicular to the side wall of the installation plate. The installation plate is provided with a locking member for locking and fixing the installation rod inside the receiving groove.

[0004] In the above patent, although the installation rod is connected to the installation plate through the connecting column, when the bobbin holder is in use, the installation rod is rotated and snapped into the inside of the card slot, so as to be able to limit the rotation of the installation rod. When the bobbin holder is not in use, the installation rod can be received inside the receiving groove, and the locking member is used to limit the installation rod from rotating back and disengaging from the receiving groove, thereby reducing the space occupied by the bobbin holder.

[0005] However, since the bobbin is directly sleeved on the installation rod and the wire outlet is that the bobbin rotates on the installation rod, after long-term use, the back surface of the installation rod is severely worn, which affects the smoothness, and further makes the wire outlet of the bobbin not smooth.

[0006] Therefore, it is necessary to propose a new technical solution to solve the above problems. Summary of the Utility Model

[0007] The utility model aims to provide a technical solution that can solve the above problems to overcome the above deficiencies.

[0008] To achieve the above object, the present utility model provides the following technical solution: A bobbin fixing mechanism for a warp knitting machine bobbin holder, including a mounting plate, one side of the mounting plate is pivotally connected with a mounting rod, a first limiting plate is fixedly arranged on the mounting rod close to one side of the mounting plate, a second limiting plate is movably sleeved on the mounting rod far from one side of the mounting plate, at least two symmetrically arranged inner support rods are provided on the opposite side surfaces of the first limiting plate and the second limiting plate, the two inner support rods expand outward in opposite sides, and the inner support rods can generate deformation and shrinkage inward.

[0009] As a further scheme of the present utility model: A regulating sleeve is arranged on the side surface of the second limiting plate far from the mounting plate, a threaded portion is formed at one end of the mounting rod far from the mounting plate, and the regulating sleeve is screwed on the threaded portion.

[0010] As a further scheme of the present utility model: The end of the inner support rod is formed with a protruding force-applying portion, and the force-applying portion is arranged as an inclined surface.

[0011] As a further scheme of the present utility model: A plurality of fixing plates are arranged on the opposite sides of the first limiting plate and the second limiting plate, the fixing plates are located inside the inner support rods, and each fixing plate corresponds to each inner support rod respectively, and an elastic member is arranged between the opposite side surfaces of the inner support rod and the fixing plate.

[0012] As a further scheme of the present utility model: The inner support rods and the fixing plates are arranged in a plurality in an annular array.

[0013] As a further scheme of the present utility model: A bearing sleeve is connected between the regulating sleeve and the second limiting plate.

[0014] As a further scheme of the present utility model: The surface of the regulating sleeve is formed with anti-slip lines.

[0015] Compared with the prior art, the beneficial effect of this technical solution is: When it is necessary to install the bobbin on the mounting rod, after the inner cavity of the bobbin is sleeved on the mounting rod and pushed towards the first limiting plate, when the inner wall of the bobbin contacts the force-applying portion of the inner support rod, the inner cavity of the bobbin squeezes the outward-expanded inner support rod inward. After the inner support rod enters the inner cavity of the bobbin, its outward-restoring outward-expansion force forms an inner support force on the bobbin. Then, the regulating sleeve and the second limiting plate are pushed onto the mounting rod, so that the inner support rods on the second limiting plate also retract into the inner cavity of the bobbin and form an inner support force on the other end of the inner cavity of the bobbin. Among them, the second limiting plate is fixed by the threaded connection between the regulating sleeve and the threaded portion on the mounting rod. At this time, the bobbin is fixedly arranged on the mounting rod through the inner support rods at both ends and will not rotate by itself, so that when the bobbin pays off the line, the bobbin can rotate along with the rotation of the mounting rod, making the pay-off more smooth;

[0016] By providing a threaded portion on the mounting rod, the distance between the second limiting plate and the first limiting plate can be adjusted by rotating the adjusting sleeve, so that disc heads of different widths can be fixed on the mounting rod for use. When removing the disc head, the second limiting plate can be taken out from the mounting rod by rotating the adjusting sleeve, thus releasing the restriction on the disc head and facilitating the removal of the disc head from the mounting rod for replacement.

[0017] When the inner support rod provided on the opposite side of the first limiting plate and the second limiting plate is squeezed by the disc head and retracts inward, the inner support rod will remember the elastic member between it and the fixing plate, causing the elastic member to contract. After contraction, the elastic member will release an outward thrust on the inner support rod, and this thrust acts on the disc head through the inner support rod, thereby enhancing the fixing effect of the inner support rod on the disc head.

[0018] Additional aspects and advantages of the present utility model will be given in part in the following description, will become apparent in part from the following description, or will be understood through the practice of the present utility model. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0027] Please refer to Figures 1-4 , a bobbin fixing mechanism for a warp knitting machine bobbin holder, comprising a mounting plate 1. One side of the mounting plate 1 is pivotally connected to a mounting rod 11. A first limiting plate 2 is fixedly provided on the side of the mounting rod 11 close to the mounting plate 1. A second limiting plate 3 is movably sleeved on the side of the mounting rod 11 away from the mounting plate 1. At least two symmetrically arranged inner support rods 4 are provided on the opposite side surfaces of the first limiting plate 2 and the second limiting plate 3. The two inner support rods 4 expand outward to opposite sides, and the inner support rods 4 can be deformed and contracted inward. A regulating sleeve 5 is provided on the side surface of the second limiting plate 3 away from the mounting plate 1. A threaded portion 12 is formed at one end of the mounting rod 11 away from the mounting plate 1. The regulating sleeve 5 is screwed onto the threaded portion 12. The end of the inner support rod 4 is formed with a protruding force-applying portion 41, and the force-applying portion 41 is provided with an inclined surface;

[0028] The present utility model is installed in the bobbin holder through the mounting plate 1. The installation method can be detachable installation such as screwing or clamping, which is not limited herein. The mounting rod 11 is rotatably connected to the mounting plate 1 through a bearing, so that the mounting rod 11 can rotate. The first limiting plate 2 is fixedly sleeved on the mounting rod 11, and the second limiting plate 3 is movably sleeved on the other end of the mounting rod 11. As Figure 1 and Figure 2 shown, the initial state of the inner support rods 4 is to expand outward, and the multiple inner support rods 4 distributed in a circular array form a shape similar to a horn;

[0029] When the pan head needs to be installed on the mounting rod 11, the adjusting sleeve 5 is rotated to remove the second limit plate 3 from the mounting rod 11, and the inner cavity of the pan head is sleeved on the mounting rod 11 and then pushed toward the first limit plate 2. When the inner wall of the pan head contacts the force-reinforcing portion 41 of the inner support rod 4, the inner support rod 4 can be deformed, so that the inner cavity of the pan head squeezes the outward-stretched inner support rod 4 inward, so that the inner support rod 4 can smoothly enter the inner cavity of the pan head. After the inner support rod 4 connected to the first limit plate 2 enters the inner cavity of the pan head, its outward-restoring force forms an internal support force on the pan head, and then the adjusting sleeve 5 is The sleeve 5 and the second limiting plate 3 are pushed onto the mounting rod 11, so that the inner support rod 4 on the second limiting plate 3 contacts the inner cavity of the pan head and retracts into the inner cavity of the pan head. Similarly, the outward expansion force that recovers outward is used to form an inner support force on the other end of the inner cavity of the pan head. The second limiting plate 3 is fixed by the threaded connection between the adjusting sleeve 5 and the threaded portion 12 on the mounting rod 11. At this time, the pan head is fixed on the mounting rod 11 by the inner support rods 4 at both ends and will not rotate by itself. When the pan head is outputting a line, the pan head can rotate with the rotation of the mounting rod 11, making the output of the line smoother.

[0030] The inclined curved surface of the force-carrying portion 41 is used to ensure that when the force-carrying portion 41 contacts and collides with the inner cavity of the pan head, the force-carrying portion 41 can be better stressed and can shrink the inner support rod 4 inwardly.

[0031] By providing the threaded portion 12 on the mounting rod 11, the distance between the second limiting plate 3 and the first limiting plate 2 can be adjusted by rotating the adjusting sleeve 5, so that pan heads of different widths can be fixed on the mounting rod 11 for use, and when disassembling a better pan head, the second limiting plate 3 can be removed from the mounting rod 11 by rotating the adjusting sleeve 5, thereby releasing the constraint on the pan head, making it convenient to remove the pan head from the mounting rod 11 and facilitate replacement.

[0032] Preferably, a plurality of fixing plates 6 are provided on the opposite sides of the first limiting plate 2 and the second limiting plate 3, the fixing plates 6 are located on the inner side of the inner support rod 4, and each fixing plate 6 corresponds to each inner support rod 4 respectively, and an elastic member 7 is provided between the inner support rod 4 and the opposite side of the fixing plate 6, wherein the elastic member 7 is a spring.

[0033] Specifically, when the inner support rod 4 arranged on the opposite side of the first limit plate 2 and the second limit plate 3 is squeezed inward by the pan head, the inner support rod 4 will remember the elastic member 7 between it and the fixed plate 6, causing the elastic member 7 to shrink, and the elastic member 7 will release an outward thrust to the inner support rod 4 after shrinking. This thrust acts on the pan head through the inner support rod 4, thereby enhancing the fixing effect of the inner support rod 4 on the pan head.

[0034] Preferably, a plurality of inner support rods 4 and fixing plates 6 are distributed in a circular array.

[0035] Specifically, when the inner support rod 4 is used to internally support and fix the disc head, by using a plurality of inner support rods 4 and a fixing plate 6 that are distributed in a circular array, the disc head can be evenly internally supported and fixed by the inner support rods 4.

[0036] Preferably, a bearing sleeve 8 is connected between the adjusting sleeve 5 and the second limiting plate 3.

[0037] Specifically, when the second limiting plate 3 drives the inner support rod 4 to move towards or out of the disc head by rotating the adjusting sleeve 5, by connecting the adjusting sleeve 5 and the second limiting plate 3 with a bearing sleeve 8, during the process of the adjusting sleeve 5 rotating and shifting, the second limiting plate 3 can remain relatively non-rotating and can follow the adjusting sleeve 5 for displacement. The resulting effect is that when the inner support rod 4 of the second limiting plate 3 needs to be inserted into the disc head, if the inner support rod 4 of the second limiting plate 3 still rotates following the adjusting sleeve 5 after contacting the inner cavity of the disc head, there will be uneven force and it will be difficult to retract into the disc head. Moreover, when the inner support rod 4 needs to be moved out of the disc head when the second limiting plate 3 is moved outwards, if the inner support rod 4 rotates during the movement, it will increase the friction between the inner support rod 4 and the inner wall of the disc head, and over time, it will cause serious wear. Therefore, connecting the adjusting sleeve 5 and the second limiting plate 3 with a bearing sleeve 8 can bring better effects for the implementation of the inner support rod 4 of the second limiting plate 3 to enter and exit the inside of the disc head.

[0038] Preferably, anti-slip lines are formed on the surface of the adjusting sleeve 5.

[0039] Through the setting of the anti-slip lines, it is convenient for the staff to rotate the adjusting sleeve 5 and avoid slipping.

[0040] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
