Description
Technical Field
[0001] This utility model relates to the field of textile equipment technology, and in particular to a warp beam mounting structure for a warp knitting machine. Background Technology
[0002] A warp knitting machine is a type of knitting equipment used to produce warp-knitted fabrics, which involves weaving warp yarns (i.e., longitudinal yarns) into loops to form a fabric. Specifically, the warp yarns are drawn parallel from the warp beam, and the number can reach hundreds to thousands. Each warp yarn is controlled by an individual guide needle. Then, the warp yarns form loops through the oscillation of the guide needles and the up and down movement of the knitting needles. The loops are connected to each other through a "chain" structure so that all the warp yarns form loops synchronously, ultimately forming a continuous fabric.
[0003] Currently, the inner diameter of the warp heads commonly used in warp knitting machines is 152 inches (corresponding to large warp heads) and 90 inches (corresponding to small warp heads). Therefore, the corresponding warp beam diameters also have two sizes (corresponding to large warp beams and small warp beams). However, the mounting structure on the warp beam frame of the warp knitting machine is relatively simple and can only accommodate one size of warp beam, making it impossible to install different sizes of warp heads and warp beams on the same warp beam frame.
[0004] In addition, when the warp beam and its pan heads need to be hoisted onto the warp beam frame, the hoisting rope is first hung in the middle of the warp beam before it is lifted. Since the warp beams are quite long, they are usually equipped with spacers and support bearings in the middle. Therefore, a certain amount of clearance is reserved at both ends of the spacers during hoisting to match the space required for the next hoisting rope operation, thus facilitating the hoisting. After hoisting, the pan heads on both sides of the spacers need to be pushed towards the spacers until the pan heads and spacers are pressed together. This process is time-consuming, labor-intensive, and has low production efficiency. Utility Model Content
[0005] To address the aforementioned problems, this invention provides a warp beam mounting structure for a warp knitting machine, which enables the installation of warp heads and warp beams of different specifications on the same warp beam frame.
[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:
[0007] This utility model provides a warp beam mounting structure for a warp knitting machine, including a warp beam frame and a warp beam. One end of the warp beam is provided with a mounting bearing. Both axial ends of the warp beam frame are respectively provided with a beam head and a bearing hole for assembling the mounting bearing. The end of the warp beam away from the mounting bearing is detachably mounted to the beam head, and the mounting bearing is detachably mounted to the bearing hole. The beam head is equipped with a detachable beam head flange, which can be used to match the installation of warp beams with smaller diameters when replacing warp beams of different diameters.
[0008] Furthermore, the shaft head flange includes an upper flange and a lower flange, for use only to connect the end of the smaller diameter shaft away from the mounting bearing.
[0009] Furthermore, the shaft head is also equipped with a shaft head cover for pressing the end of the shaft away from the mounting bearing. The upper flange and the lower flange together form a split structure with mounting holes. The lower flange is detachably installed on one side of the shaft head, and the upper flange and the shaft head cover are detachably installed on the other opposite side of the shaft head.
[0010] Furthermore, there are two mounting bearings and two warp shafts, one large warp shaft and one small warp shaft; the inner diameter of the inner ring of one mounting bearing corresponds to the larger diameter of the large warp shaft, and the inner diameter of the inner ring of the other mounting bearing corresponds to the smaller diameter of the small warp shaft; the outer diameters of the two mounting bearings are the same.
[0011] Furthermore, the outer ring of the mounting bearing is mounted on the warp shaft bracket; the inner ring of the mounting bearing is used to mount the end of the warp shaft away from the shaft head, and the inner diameter of the inner ring of the mounting bearing corresponds to the outer diameter of the end of the warp shaft away from the shaft head of different diameters.
[0012] Furthermore, a spacer is fitted on the warp shaft, and a support bearing is mounted on the outer circumferential surface of the spacer; the two axial ends of the spacer are always in contact with the disc head on the warp shaft.
[0013] Furthermore, the length of the spacer along its axial direction corresponds to the spatial distance required for the hoisting rope operation during the hoisting of the warp shaft.
[0014] Furthermore, the spacer sleeve is provided with a positioning shaft hole, and the outer circumferential surface of the warp shaft is provided with a positioning hole that mates with the positioning shaft hole; the spacer sleeve is positioned on the warp shaft through the combined cooperation of the positioning shaft, the positioning shaft hole, and the positioning hole.
[0015] The technical solution provided by this utility model has the following beneficial effects:
[0016] By using the bearing hole and the shaft head together, a warp beam with a larger diameter and its corresponding disc head can be installed on the warp beam frame. When replacing a warp beam with a smaller diameter, the bearing hole, the shaft head, and the shaft head flange can also be used together to install the warp beam with a smaller diameter and its corresponding disc head on the same warp beam frame. Therefore, this utility model has good universality and ease of operation. Attached Figure Description

[0022] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.
[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0024] Reference Figures 1 to 5 This embodiment provides a warp beam mounting structure for a warp knitting machine (hereinafter referred to as the warp beam mounting structure) for mounting the warp beam 1 of the warp knitting machine and its corresponding warp head 2 on the warp beam frame 10 of the warp knitting machine.
[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the warp shaft mounting structure of this embodiment includes a warp shaft frame 10 and a warp shaft 1. The axial ends of the warp shaft frame 10 are respectively provided with bearing holes 101 and shaft heads 3 arranged at intervals. The two ends of the warp shaft 1 in its axial direction are defined as a first end 11 and a second end 12. The first end 11 is equipped with a mounting bearing 5, and the second end 12 corresponds to the shaft head 3. The second end 12 of the warp shaft 1, which is away from the mounting bearing 5, is detachably assembled to the shaft head 3, and the mounting bearing 5 is detachably assembled to the bearing hole 101.
[0026] The shaft head 3 is equipped with a detachable shaft head flange 4, which is used to match the installation of a smaller diameter warp shaft when changing warp shafts 1 of different diameters.
[0027] In this embodiment, there are two warp shafts 1 and two mounting bearings 5. The two warp shafts 1 are a large warp shaft 1 and a small warp shaft 1. The inner diameter of the inner ring of one mounting bearing 5 corresponds to the first end 11 of the larger diameter large warp shaft 1, and the inner diameter of the inner ring of the other mounting bearing 5 corresponds to the first end 11 of the smaller diameter small warp shaft 1. The outer diameters of the two mounting bearings 5 are the same, and the outer diameters of the two mounting bearings 5 are the same as the size of the bearing hole 101. Therefore, this embodiment can achieve adaptability and universality between the first end 11 of two warp shafts 1 with different diameters and the bearing hole 101. Of course, in other embodiments, at least two mounting bearings 5 can also be installed on the first end 11 of the smaller diameter warp shaft 1 to ensure sufficient support strength.
[0028] When the large warp beam 1 or the small warp beam 1 is installed on the warp beam holder 10, the outer ring of the mounting bearing 5 on the large warp beam 1 or the small warp beam 1 is installed in the bearing hole 101. Since the inner diameter of the inner ring of the mounting bearing 5 corresponds to the outer diameter of the first end 11 of the warp beam 1 of different diameters, the inner rings of the mounting bearings 5 of different inner ring models can ensure that they match the first end 11 of the warp beam 1 of different diameters.
[0029] More specifically, such as Figure 4 and Figure 5 As shown, the shaft head flange 4 includes an upper flange 41 and a lower flange 42, which are used only for connecting the second end 12 of the smaller diameter shaft 1.
[0030] The shaft head 3 is also equipped with a shaft head cover 31 for pressing the second end 12 of the shaft 1. The upper flange 41 and the lower flange 42 together form a split structure with holes. The lower flange 42 is detachably installed on the bottom side of the shaft head 3, and the upper flange 41 and the shaft head cover 31 are detachably installed on the other opposite top side of the shaft head 3.
[0031] like Figure 2 , Figure 4 and Figure 5 As shown, when installing the small warp shaft 1 with a smaller diameter, first remove the shaft head cover 31 and the upper flange 41 together. Then place the second end 12 of the warp shaft 1 on the shaft head 3 and the lower flange 42, and then cover it with the shaft head cover 31 and the upper flange 41. After that, tighten the shaft head cover 31 with screws. In this way, the small warp shaft 1 and the small disc head 2 on it are fixed on the small warp shaft 1 and a reliable connection is achieved with the shaft head flange 4 and the shaft head 3.
[0032] When switching to the installation of a larger diameter shaft 1, only the shaft head flange 4 on the shaft head 3 needs to be removed. That is, without the cooperation of the shaft head flange 4, the large diameter shaft 1 and the shaft head 3 can be reliably connected by the shaft head 3 alone.
[0033] By cooperating with the bearing hole 101 and the shaft head 3, the warp shaft 1 with a larger diameter and its corresponding disc head 2 can be installed on the warp shaft frame 10. When replacing the warp shaft 1 with a smaller diameter, the warp shaft 1 with a smaller diameter and its corresponding disc head 2 can be installed on the same warp shaft frame 10 by cooperating with the bearing hole 101, the shaft head 3 and the shaft head flange 4. Therefore, this embodiment has good universality and ease of operation.
[0034] Further preferred, such as Figure 2 As shown, a spacer 6 is fitted on the warp shaft 1, and a support bearing 7 is mounted on the outer circumferential surface of the spacer 6. The length of the spacer 6 along its axial direction corresponds to the space distance L required for the operation of the hoisting rope 8 when the warp shaft 1 is hoisted. Therefore, in this embodiment, it is not necessary to pre-set the clearance space corresponding to the space distance L required for the operation of the hoisting rope 8 during hoisting. Instead, the two axial ends of the spacer 6 are always abutted against the disc head 2 on the warp shaft 1.
[0035] In this specific embodiment, the spacer 6 is provided with a plurality of positioning shaft holes 61, and the outer peripheral surface of the shaft 1 is provided with positioning holes 13 that cooperate with the positioning shaft holes 61.
[0036] When installing the pan head 2, the spacer 6 is positioned on the warp shaft 1 by the cooperation of the positioning shaft 9, the positioning shaft hole 61 and the positioning hole 13. Each time the pan head 2 is disassembled or installed, the pan head 2 can be pushed to the installation position that is in close contact with the spacer 6, and the pan head 2 on both sides can be locked and fixed. This avoids the need to find the installation position every time the pan head 2 is disassembled or installed, and also eliminates the need to reserve space for the lifting rope 8 when installing the pan head 2. This reduces the difficulty of operation, saves time and effort, and thus significantly improves production efficiency.
[0037] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
