Description

Technical Field

[0001] This invention belongs to the field of circular knitting machine feeder adjustment technology, specifically relating to a circular knitting machine feeder positioning device. Background Technology

[0002] Circular knitting machines are commonly used knitting equipment in knitting production. They feed yarn sequentially from the weft direction into working needles, and then the yarn is bent into loops and interlocked by the loop-forming mechanism to form knitted fabric. The yarn feed nozzle of the circular knitting machine is one of its key components, mainly responsible for guiding the yarn and feeding it accurately onto the needles. Its performance and installation accuracy have a significant impact on the quality of the knitted fabric and the production efficiency.

[0003] However, existing circular knitting machines rely solely on visual inspection by operators or simple backing plates to fix the yarn feeder when installing it. This process is time-consuming, and the installation accuracy of the parts is often inaccurate, which can easily lead to uneven yarn feeding and large fluctuations in yarn tension, resulting in low efficiency in the installation of the yarn feeder. Summary of the Invention

[0009] The first positioning component includes a first adjustment groove that is horizontally opened through the top of the positioner. An adjustment rod is horizontally movably disposed in the first adjustment groove. The adjustment rod moves in the first adjustment groove along its horizontal axial center line for horizontal adjustment of the yarn feed nozzle.

[0010] The second positioning component is located below the first positioning component. It includes a second adjustment groove vertically opened on any side of the positioner. An adjustment seat is vertically movable in the second adjustment groove. The adjustment seat moves in the second adjustment groove along its vertical direction for vertically adjusting the yarn feeder.

[0011] As a further improvement, the positioner includes a positioning section and an adjustment section integrally connected to the top of the positioning section, and the bottom of the positioning section is provided with a fixing hole for fixing the positioner.

[0012] As a further improvement, the positioner is also provided with at least one limiting component, which includes a positioning hole opened on the positioner and a positioning rod movably disposed in the positioning hole, for limiting the positioning of the first positioning component and / or the second positioning component, so as to control the degree of adjustment of the yarn feeder.

[0013] As a further improvement, the positioner is provided with two limiting components, wherein the limiting component on the first positioning component is correspondingly located at the top of the adjusting rod to limit the adjusting rod. Its positioning hole is vertically opened at the top of the positioning section and is connected to the first adjusting groove. One end of its positioning rod passes through the positioning hole and the first adjusting groove in sequence and abuts against the outer wall of the adjusting rod. The other end is provided with a positioning button for adjusting the penetration depth of the positioning rod.

[0014] As a further improvement, the limiting component on the second positioning component is located on the side corresponding to the adjusting seat to limit the adjusting seat. Its positioning hole is opened laterally in the second adjusting groove, thereby making the bottom of the positioning section pass through laterally. One end of its positioning rod passes through and extends into the second adjusting groove and the positioning hole in sequence, and the other end is provided with a positioning button to adjust the penetration depth of the positioning rod.

[0015] As a further improvement, the positioning hole and the positioning rod in the limiting assembly are connected by either a threaded connection or an embedded connection.

[0016] As a further improvement, the adjusting seat includes an adjusting side plate that is vertically movable in the second adjusting groove and an adjusting base plate that is at least partially connected to the bottom of the adjusting side plate, wherein the adjusting base plate is horizontally arranged.

[0017] As a further improvement, a side hole is horizontally provided on the adjustment side plate, the positioning rod extends through the side hole into the positioning hole, and the end face of the positioning button near the positioning rod abuts against the adjustment side plate.

[0018] As a further improvement, the vertical opening depth of the side hole is greater than the radial length of the positioning rod, and the horizontal opening depth of the side hole is less than the radial length of the positioning button, thereby enabling the adjusting seat to move vertically and securely abut against the limiting component within the side hole.

[0019] As a further improvement, a connecting section is provided inclined between the positioning section and the adjustment section, thereby forming a placement space for the circular knitting machine on the inner side of the positioning section, the adjustment section and the connecting section.

[0043] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0044] Example 1

[0045] like Figure 1 , 2 As shown, the structure of a circular knitting machine feeder positioning device according to an embodiment of the present invention will be described in detail. It includes a positioner 10, and the top of the positioner 10 is respectively provided with a first positioning component 20 and a second positioning component 30.

[0046] The first positioning component 20 includes a first adjustment groove 201 that is horizontally opened through the top of the positioner 10. An adjustment rod 202 is horizontally movably disposed in the first adjustment groove 201. The adjustment rod 202 moves in the first adjustment groove 201 along its horizontal axial center line and is used to horizontally adjust the yarn feeder.

[0047] The second positioning component 30 is located below the first positioning component 20. It includes a second adjustment groove 301 vertically opened on any side of the positioner 10. An adjustment seat 302 is vertically movably disposed in the second adjustment groove 301. The adjustment seat 302 moves in the second adjustment groove 301 along its vertical direction for vertically adjusting the yarn feeder.

[0048] Please see Figure 1As shown, the positioner 10 includes a positioning section 101 and an adjustment section 102 integrally connected to the top of the positioning section 101. The positioning section 101 is used by the user to hold and use it. The adjustment section 102 is provided with a first positioning component 20 and a second positioning component 30. In addition, the bottom of the positioning section 101 is provided with a fixing hole 103. The positioner 10 can be fixed to the circular knitting machine with screws through the fixing hole 103. When installing, the inner side of the positioner 10 is installed facing the yarn feeder fixing seat of the circular knitting machine, and the positioning section 101 is set facing the weft yarn feeder of the circular knitting machine. Then, the first limiting component and the second limiting component on the positioning section 101 can adjust the yarn feeder.

[0049] Please see Figure 1-2 As shown, the positioner 10 is also provided with at least one limiting component 40, including a positioning hole 401 opened on the positioner 10 and a positioning rod 402 movably disposed in the positioning hole 401, for limiting the positioning of the first positioning component 20 and / or the second positioning component 30. Its limiting function is reflected in the fact that the positioning rod 402 of the limiting component 40 abuts against the adjusting seat or adjusting rod by moving in the positioning hole 401, so that it cannot continue to move, thereby achieving the purpose of movement restriction, thereby controlling the degree of adjustment of the yarn feed nozzle, that is, keeping the degree of adjustment of the yarn feed nozzle at a certain precision each time, and combining the adjustment in the horizontal and vertical directions to ensure the uniformity of yarn feeding and prevent large fluctuations in yarn tension.

[0050] Please see Figure 1-2As shown, in this embodiment, the positioner 10 preferably has two limiting components 40, which are used to control the first positioning component 20 and the second positioning component 30 respectively. Each limiting component 40 includes a positioning hole 401 opened on the positioner 10 and a positioning rod 402 movably disposed in the positioning hole 401. The limiting component 40 provided on the first positioning component 20 is correspondingly disposed at the top of the adjusting rod 202 to limit the adjusting rod 202. Its positioning hole 401 is vertically opened at the top of the positioning section 101 and is connected to the first adjusting groove 201, so that the positioning rod 402 movably disposed in the positioning hole 401 can move and abut against the first adjusting groove 201. Then, one end of the positioning rod 402 passes through the positioning hole 401 and the first adjusting groove 201 in sequence and abuts against the outer wall of the adjusting rod 202. The other end is provided with a positioning button 403 for adjusting the penetration depth of the positioning rod 402. In other words, the user can operate the positioning button 403 to synchronously adjust the penetration depth of the positioning rod 402 in the positioning hole 401, thereby adjusting the degree of compression and fastening between the positioning rod 402 and the outer wall of the adjusting rod 202, so as to achieve the adjustment and restriction effect of the adjusting rod 202. In this embodiment, the first adjusting groove 201 of the first positioning component 20 is horizontally opened on the positioning section 101, and the adjusting rod 202 moves horizontally in the first adjusting groove 201 accordingly, so that the yarn feeder can be adjusted horizontally relative to the circular weft machine based on this. After the adjustment is completed, the limiting component 40 is used to control the adjusting rod 202 to remain stationary in the corresponding adjustment position. Thus, the horizontal installation position of the yarn feeder can be adjusted based on the current position of the adjusting rod 202, so as to realize the quick installation and positioning of the yarn feeder, and ensure that the accuracy of each yarn feeder adjustment is consistent, ensuring the uniformity of yarn feeding and preventing large fluctuations in yarn tension.

[0051] Please see Figure 2-3As shown, in this embodiment, the limiting component 40 on the second positioning component 30 is located on the side corresponding to the adjusting seat 302. Since the second adjusting groove 301 of the second positioning component 30 in this embodiment is vertically located on any side of the positioner 10, the limiting component used to restrict its movement will also be located on the corresponding side to limit the adjusting seat 302. Specifically, the positioning hole 401 in the limiting component 40 of the second positioning component 30 is opened laterally in the second adjusting groove 301, thereby making the bottom of the positioning section 101 laterally pass through. That is to say, the positioning hole 401 is opened in the second adjusting groove 301 and simultaneously opens both sides of the positioning section 101 laterally. One end of the positioning rod 402 extends into the second adjusting groove 301 and the positioning hole 401 in sequence, and the other end is provided with a positioning button 403 for adjusting the penetration depth of the positioning rod 402. That is to say, the user can operate... The positioning button 403 synchronously adjusts the penetration depth of the positioning rod 402 in the positioning hole 401, thereby adjusting the degree of compression and fastening between the positioning rod 402 and the outer wall of the adjusting seat 302, so as to achieve the adjustment and restriction effect on the adjusting seat 302. In this embodiment, the second adjusting groove 301 of the second positioning component 30 is vertically opened on one side of the positioning section 101, and the adjusting seat 302 moves vertically in the second adjusting groove 301 accordingly, so that the yarn feeder can be adjusted vertically by the circular weft machine based on this. After the adjustment is completed, the limiting component 40 is used to control the adjusting seat 302 to remain stationary in the corresponding adjustment position. Thus, the vertical flat position of the yarn feeder can be adjusted based on the current position of the adjusting seat 302, so as to realize the quick installation and positioning of the yarn feeder, and ensure that the accuracy of each yarn feeder adjustment is consistent, ensuring the uniformity of yarn feeding and preventing large fluctuations in yarn tension.

[0052] To ensure more stable adjustment, the positioning hole 401 and positioning rod 402 in the limiting component 40 of the first positioning component 20 and the second positioning drill 30 are connected by either a threaded connection or an embedded connection. In this embodiment, a threaded connection is preferred. Specifically, the positioning rod 402 has an external thread on its outer wall, and the positioning hole 401 has an internal thread that connects with the external thread on its inner wall. As a feasible implementation method, in order to reduce costs, the positioning rod 402 can be made of a screw or bolt of suitable diameter and used with a screwdriver, while the positioning hole 401 is made of a threaded hole that is compatible with it, so as to achieve the purpose of quick positioning, which is quick to operate and convenient to select materials.

[0053] Please see Figure 3-6As shown, in order to better adjust the second positioning component 30, the adjusting seat 302 includes an adjusting side plate 3021 vertically movably disposed within the second adjusting groove 301 and an adjusting base plate 3022 at least partially connected to the bottom of the adjusting side plate 3021. The adjusting base plate 3022 is horizontally disposed. In this embodiment, the adjusting seat 302 consists of a vertical adjusting side plate 3021 and a horizontal adjusting base plate 3022. The adjusting side plate 3021 is mainly used for vertical sliding within the second adjusting groove 301, while the adjusting base plate 3022... The second positioning component 30 is used to horizontally lift the yarn feeder of the circular weft machine to achieve vertical adjustment. Furthermore, the limiting component 40 on the second positioning component 30 is adjusted by the following structure: a side hole 3023 is horizontally opened on the adjusting side plate 3021, which horizontally passes through both sides of the vertically arranged adjusting side plate 3021. Thus, the side hole 3023, the second adjusting groove 301, and the positioning hole 401 are connected. Therefore, when the positioning rod 402 restricts the adjustment of the adjusting seat 302, it extends through the side hole 3023 into the positioning hole. Inside 401, the end face of the positioning button 403 near the positioning rod 402 abuts against the adjusting side plate 3021. At this time, the end face of the positioning button 403 presses against the adjusting seat 302, so that the adjusting seat 302 is tightly fixed in the second adjusting groove 301 and will not slip, making adjustment convenient and quick. In addition, it should be noted that the vertical opening depth of the side hole 3023 is greater than the radial length of the positioning rod 402, and the horizontal opening depth of the side hole (3023) is less than the radial length of the positioning button 403, so that the side hole 3023... 023 can provide sufficient space for the vertical movement of the adjusting side plate 3021, and can make the positioning button 403 and the adjusting side plate 3021 firmly abut against each other and remain stable. The opening depth can be designed according to actual needs. As a feasible embodiment, an annular gasket can also be set between the positioning button 403 and the adjusting side plate 3021, so that the positioning button 403 and the adjusting side plate 3021 are more firmly and stably fixed, and the adjusting seat 302 can move vertically within the side hole 3023 relative to the limiting component 40.

[0054] Please see Figure 1 As shown in Figures 7 and 8, a connecting section 104 extends obliquely between the positioning section 101 and the adjusting section 102. Thus, the inner sides of the positioning section 101, the adjusting section 102, and the connecting section 104 form a placement space that fits the circular weft machine. When the positioning device is installed on the circular weft machine to adjust the yarn feed nozzle, this placement space can fit the shape of the inner wall of the circular weft machine, making it convenient to install and adjust the yarn feed nozzle.

[0055] Example 2

[0056] For the sake of brevity, the parts that are the same as in Embodiment 1 will not be described again. The main focus here is on the structure that is different from that in Embodiment 1 of the present invention. The only difference between Embodiment 2 and Embodiment 1 is the second positioning component.

[0057] Please see Figure 9-10 As shown, in order to prevent damage to the connection point between the adjusting side plate 3021 and the adjusting base plate 3022 after long-term use of the positioning device, in this embodiment, two second positioning components 30 are provided at the bottom of the positioning section 101, respectively located on opposite sides of the bottom of the positioning section 101. Each side of the positioning section 101 has a vertically opened second adjusting groove 301, and each second adjusting groove 301 has a vertically sliding adjusting side plate 3021. In order to avoid damage or breakage caused by only a part of the adjusting side plate 3021 and the adjusting base plate 3022 being connected in Embodiment 1, in this embodiment, the adjusting side plates 3021 on both sides are connected to an adjusting base plate 3022 at the bottom, increasing the connection part between the two to make the force more even.

[0058] Furthermore, a limiting component 40 will be provided for each of the second positioning components 30 on both sides. That is, each side will be provided with a positioning hole 401 and a positioning rod 402. It should be noted that in order to prevent the limiting components 40 from contradicting each other, the positioning holes 401 on both sides will be staggered vertically. Thus, during adjustment, the adjusting side plates 3021 on both sides will move vertically in sync within the second adjusting grooves 301 on both sides. When adjusted to the appropriate position, the adjusting side plates 3021 on both sides will be fixed to prevent them from slipping. That is, after adjustment, the limiting component 40 is used to control the adjusting seat 302 to remain stationary in the corresponding adjustment position. The fastening design on both sides also ensures the stability of the fixing of the adjusting seat 302 and the second adjusting groove 301. This allows the yarn feeder to be adjusted vertically relative to the circular weft machine based on this, thereby achieving quick installation and positioning of the yarn feeder.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0060] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
