Description

Technical Field

[0001] This utility model belongs to the field of knitting machine technology, specifically an adjustable weft knitting machine. Background Technology

[0002] The sinker in a weft knitting machine is a crucial component. Its main function is to work with the knitting needles to loop the yarn during the knitting process. Specifically, the sinker can move radially under the control of the sinker cam while simultaneously moving in a circular motion, thereby clamping and rotating the yarn, further ensuring the stability of the knitting and the quality of the product. In actual operation, the movement trajectory and method of the sinker can be adjusted according to specific knitting needs to achieve different knitting effects.

[0003] When adjusting the sinkers in a weft knitting machine, the sinker triangles need to be adjusted. However, with hundreds of yarns in a weft knitting machine, there are numerous sinker triangles, making individual adjustment time-consuming and labor-intensive. Furthermore, specialized adjustment instruments are required for testing and adjustment, further increasing manpower and time. If there are deviations during adjustment, the fabric knitting quality will be affected, potentially necessitating repeated adjustments and increasing production costs. This highlights the inconvenience of adjusting sinker triangles in existing weft knitting machines.

[0004] Chinese Patent CN213113746U discloses an adjustment mechanism for a weft knitting machine and the machine itself. The adjustment mechanism includes an adjustment mechanism, a yarn feeding mechanism, and a frame. The adjustment mechanism comprises an adjustment unit, sinker triangles, and a sinker plate frame. Multiple pairs of adjustment units and sinker triangles are arranged in pairs and evenly spaced on the sinker plate frame. Each adjustment unit includes an adjustment element and a fixing ring. The adjustment element is reciprocally movable and fitted within the fixing ring. The sinker triangles are located on the drive end of the adjustment element and move with it. By connecting an adjustment unit to the sinker triangle and adjusting the adjustment element to move the sinker triangle accordingly, the sinker can be adjusted directly on the weft knitting machine without the need for additional tools, thus improving the convenience and efficiency of adjustment.

[0005] However, the above has the following shortcomings:

[0006] Each adjustment component in the aforementioned patent is independent of the others, making batch adjustment impossible. It still requires manual adjustment of each component, which is time-consuming and laborious. Furthermore, the individual adjustment method results in poor consistency and is prone to errors, thus affecting the operation of the weft knitting machine.

[0007] The aforementioned patent uses a spring to restrict the position of the settling plate triangle after adjustment. However, the spring restriction is not stable. When the settling plate passes through the settling plate triangle, the initial center of the settling plate triangle is easily deviated, which causes the settling plate to fail to reach the specified working position, thereby affecting the quality of the fabric. Utility Model Content

[0008] To overcome the shortcomings of existing technologies, this invention solves the technical problem by synchronously driving each adjusting component with a toothed ring, enabling simultaneous adjustment of the settling plate triangles on all adjusting components. No special tools are required, making adjustment convenient, simple, and significantly improving efficiency. This avoids the waste of labor and time associated with manual adjustments. Furthermore, the synchronous adjustment of all adjusting components via the toothed ring ensures high accuracy and consistency, and allows for locking of the adjusted components to prevent the settling plate triangles from shifting during weft knitting machine operation. Additionally, this patent utilizes multiple independently controlled electromagnetic push-pull devices to achieve independent adjustment of one or more specific adjusting components, resulting in more precise and controllable adjustment and improved adjustment effectiveness.

[0009] To achieve the above objectives, this utility model provides the following technical solution: an adjustable weft knitting machine, comprising a weft knitting machine body, an adjusting seat fixedly connected to the weft knitting machine body, and multiple bottom shells evenly distributed and fixedly connected to the adjusting seat in a circumferential direction. All the bottom shells are assembled together to form a complete ring. A toothed ring is rotatably connected to the outer edge of the ring formed by the bottom shells. A transmission component that is driven and connected to the toothed ring is provided in each bottom shell. A top shell is fixedly connected to the upper end of each bottom shell. An adjusting component that is driven and connected to the transmission component is provided in each top shell.

[0010] By synchronously driving each adjustment component with a gear ring, the settlement plate triangles on all adjustment components can be adjusted simultaneously without special tools. The adjustment is convenient and simple, greatly improving the adjustment efficiency and avoiding the waste of labor and time costs caused by manual adjustment one by one.

[0011] Furthermore, by synchronously adjusting all the adjustment components through the gear ring, the adjustment accuracy and consistency are improved.

[0012] Furthermore, the adjusting component includes a second lead screw, and each top shell is rotatably connected to a second lead screw. A sliding groove is provided on the upper side of each top shell at the position corresponding to the second lead screw. A sliding seat for installing the settling plate triangle is slidably connected in each sliding groove. Each sliding seat is meshed and driven by the corresponding second lead screw. A second bevel gear is fixedly connected to one end of each second lead screw located in the top shell.

[0013] Using a lead screw pair as the transmission structure for the adjustment component improves the stability and accuracy of the adjustment process.

[0014] Furthermore, the transmission component includes a lifting shaft, a sleeve rotatably connected to each lifting shaft, a spur gear fixedly connected to each sleeve, each spur gear meshing with a gear ring for transmission, and a first bevel gear fixedly connected to the upper side of each sleeve at the spur gear position, each first bevel gear meshing with a second bevel gear for transmission.

[0015] Furthermore, each lifting shaft has a slidably connected bearing seat at its bottom end, each bearing seat is fixedly connected to the bottom of the base shell, and a spring surrounding the outer side of the bearing seat is connected between each lifting shaft and its corresponding bearing seat. A locking block is fixedly connected to the top end of each lifting shaft. A push-pull plate is rotatably connected to each sleeve at the lower side of the spur gear, and an electromagnetic push-pull device is drivenly connected to the end of each push-pull plate away from the sleeve. Each electromagnetic push-pull device is fixedly connected to the bottom side of the base shell.

[0016] By setting a locking block, under the push and pull of the electromagnetic push and pull device, the locking block locks the second bevel gear at the same time as the spur gear disengages from the gear ring and the first bevel gear disengages from the second bevel gear, thereby ensuring that the sliding seat will not shift after adjustment and ensuring the stability of the weft knitting machine operation.

[0017] Furthermore, by using multiple independently controlled electromagnetic push-pull devices, one or more specific adjustment components can be adjusted independently, thereby making the adjustment more precise and controllable and improving the adjustment effect.

[0018] Furthermore, a lead screw seat is fixedly connected to one end of the upper side of the adjusting seat, and a first lead screw is rotatably connected inside the lead screw seat. The first lead screw is meshed with a gear ring for transmission, and a handwheel is fixedly connected to one end of the first lead screw extending out.

[0019] In summary, compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] By synchronously driving each adjustment component with a gear ring, the settlement plate triangles on all adjustment components can be adjusted simultaneously without special tools. The adjustment is convenient and simple, greatly improving the adjustment efficiency and avoiding the waste of labor and time costs caused by manual adjustment one by one.

[0021] Furthermore, by synchronously adjusting all the adjustment components through the gear ring, the adjustment accuracy and consistency are improved.

[0022] It can lock the adjusted components to prevent the settling triangle from shifting during weft knitting machine operation.

[0023] By using multiple independently controlled electromagnetic push-pull devices, one or more specific adjustment components can be adjusted independently, thereby making the adjustment more precise and controllable and improving the adjustment effect. Attached Figure Description

Detailed Implementation

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0034] Example 1:

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an adjustable weft knitting machine includes a weft knitting machine body 10. An adjusting seat 17 is fixedly connected to the weft knitting machine body 10. Multiple bottom shells 15 are evenly distributed and fixedly connected to the adjusting seat 17 in a circumferential direction. All the bottom shells 15 are assembled to form a complete ring. A toothed ring 14 is rotatably connected to the outer edge of the ring formed by the bottom shells 15. A transmission component that is pulsatorically connected to the toothed ring 14 is provided in each bottom shell 15. A top shell 16 is fixedly connected to the upper end of each bottom shell 15. An adjusting component that is pulsatorically connected to the transmission component is provided in each top shell 16. A lead screw seat 11 is fixedly connected to one end of the upper side of the adjusting seat 17. A first lead screw 12 is rotatably connected to the lead screw seat 11. The first lead screw 12 is meshed and pulsatorically connected to the toothed ring 14. A handwheel 13 is fixedly connected to one end of the first lead screw 12 extending outward.

[0036] By synchronously driving each adjustment component through the gear ring 14, the settlement plate triangles on all adjustment components can be adjusted simultaneously without special tools. The adjustment is convenient and simple, greatly improving the adjustment efficiency and avoiding the waste of labor and time costs caused by manual adjustment one by one.

[0037] Furthermore, all adjustment components are adjusted synchronously through the gear ring 14, resulting in good adjustment accuracy and high adjustment consistency.

[0038] like Figure 5 , Figure 6 and Figure 7 As shown, the adjusting component includes a second lead screw 20. Each top shell 16 is rotatably connected to a second lead screw 20. A groove 19 is provided on the upper side of each top shell 16 at the corresponding position of the second lead screw 20. A sliding seat 18 for installing the settling plate triangle is slidably connected in each groove 19. Each sliding seat 18 is meshed and driven by the corresponding second lead screw 20. A second bevel gear 30 is fixedly connected to one end of each second lead screw 20 located in the top shell 16.

[0039] Using a lead screw pair as the transmission structure for the adjustment component improves the stability and accuracy of the adjustment process.

[0040] like Figure 5 , Figure 6 and Figure 7 As shown, the transmission component includes a lifting shaft 24, a sleeve 26 rotatably connected to each lifting shaft 24, a spur gear 28 fixedly connected to each sleeve 26, each spur gear 28 meshing with a gear ring 14 for transmission, and a first bevel gear 29 fixedly connected to each sleeve 26 on the upper side of the spur gear 28, each first bevel gear 29 meshing with a second bevel gear 30 for transmission.

[0041] like Figure 5 , Figure 6 and Figure 7As shown, each lifting shaft 24 has a slidably connected bearing seat 22 at its bottom end, and each bearing seat 22 is fixedly connected to the bottom of the base shell 15. A spring 23 is connected between each lifting shaft 24 and its corresponding bearing seat 22, and a locking block 25 is fixedly connected to the top of each lifting shaft 24. A push-pull plate 27 is rotatably connected to each sleeve 26 at the lower side of the spur gear 28. An electromagnetic push-pull device 21 is drivenly connected to the end of each push-pull plate 27 away from the sleeve 26, and each electromagnetic push-pull device 21 is fixedly connected to the bottom side of the base shell 15.

[0042] By setting the locking block 25, under the push and pull of the electromagnetic push and pull device 21, the locking block 25 locks the second bevel gear 30 at the same time that the spur gear 28 disengages from the gear ring 14 and the first bevel gear 29 disengages from the second bevel gear 30, thereby ensuring that the sliding seat 18 will not shift after adjustment and ensuring the stability of the weft knitting machine operation.

[0043] Furthermore, by using multiple independently controlled electromagnetic push-pull devices 21, one or more specific adjustment components can be adjusted independently, thereby making the adjustment more precise and controllable and improving the adjustment effect.

[0044] In this embodiment, before using the weft knitting machine, the operator installs the settling plates on the corresponding sliding seats 18 and connects each electromagnetic push-pull device 21 to the control system. At this time, each spur gear 28 meshes with the gear ring 14, and each first bevel gear 29 meshes with the corresponding second bevel gear 30. The operator turns the handwheel 13, causing the first lead screw 12 to drive the gear ring 14 to rotate, thereby the gear ring 14 drives all the second bevel gears 30 to rotate. In turn, each second lead screw 20 drives the sliding seat 18 to slide in the slide groove 19, thereby adjusting the triangle of the settling plate. By synchronously driving each adjusting component through the gear ring 14, the triangle of the settling plate on all adjusting components can be adjusted simultaneously. No special tools are required, the adjustment is convenient and simple, and the adjustment efficiency is greatly improved. It avoids the waste of labor and time costs caused by manual adjustment one by one. Furthermore, by synchronously adjusting all adjusting components through the gear ring 14, the adjustment accuracy is good and the adjustment consistency is high.

[0045] After adjustment, the control system retracts all electromagnetic push-pull devices 21, pulling the push-pull plate 27 downwards. This causes the sleeve 26, along with the spur gear 28 and the first bevel gear 29, to move downwards, disengaging from the gear ring 14 and the second bevel gear 30, respectively. This prevents the rotation of the gear ring 14 from affecting the position of the sliding seat 18. The lifting shaft 24 moves downwards along with the sleeve 26, causing the locking block 25 to engage with the second bevel gear 30. Since the locking block 25 remains stationary, it locks the second bevel gear 30, ensuring that the sliding seat 18 will not shift after adjustment and guaranteeing the stability of the weft knitting machine. When readjustment is needed, the control system again drives the electromagnetic push-pull devices 21 to extend, causing the spur gear 28 and the first bevel gear 29 to re-engage with the gear ring 14 and the second bevel gear 30, respectively. Then, the gear ring 14 is driven to rotate for adjustment.

[0046] When it is necessary to adjust the settling plates at different positions according to a specific weaving process, the control system individually controls one or more specific electromagnetic push-pull devices 21 to retract, thereby causing specific spur gears 28 and the first bevel gear 29 to disengage from the gear ring 14 and the second bevel gear 30, respectively. This allows the gear ring 14 to drive and adjust other adjustment components, making the adjustment more precise and controllable and improving the adjustment effect.

[0047] Example 2:

[0048] like Figure 8 As shown, one end of each second lead screw 20 extending out of the top shell 16 is connected to a potentiometer 31, and each potentiometer 31 is fixedly connected to the top shell 16.

[0049] As a further embodiment, by setting a potentiometer 31 and connecting it to each second lead screw 20, the number of rotations of each second lead screw 20 can be obtained, thereby obtaining the accurate position of the sliding seat 18. By connecting the potentiometer 31 to the control system, the operator can promptly know the position of the sliding seat 18 and the settling plate triangle, which facilitates the adjustment work.
