Description

Technical Field

[0001] This utility model relates to the field of weft knitting circular knitting machine technology, specifically a weft straightening device for a weft knitting circular knitting machine. Background Technology

[0002] In the development of existing knitting technology, due to the special loop knitting principle of the weft knitting circular knitting machine and factors such as yarn twist, the loops of the knitted fabric are very prone to skew in a free state, which causes the vertical loops in the warp and the horizontal loops in the fabric to twist, resulting in weft skew.

[0003] For example, the automatic weft straightening device for a circular knitting machine disclosed in announcement number "CN219174736U" involves manually rotating a handle to reverse it. This reverse rotation drives a gear to rotate in the same direction, simultaneously moving two racks towards one end. The movement of the racks moves the positioning seat inward, compressing a spring as they move. When the positioning seat moves inward and disengages from the positioning hole, the insert can be removed from the mounting slot, allowing the mounting plate to be detached from the vertical plate for easy replacement of the weft skew image detector. This invention uses the elasticity of the spring to fix the position of the racks, which in turn fixes the positioning seat within the positioning hole. The snap-fit ​​connection between the positioning hole and the positioning seat facilitates the fixing of the mounting plate, optimizing the ease of disassembly and cleaning of the weft skew image detector.

[0004] However, in actual operation, since there is no locking structure between the gear and rack, when disassembling or installing the weft skew image detector, the operator needs to keep holding the throttle handle. The mounting plate that fixes the weft skew image detector has a certain area, which is difficult for the operator to hold with one hand. This makes it difficult for a single person to operate when disassembling or installing the weft skew image detector, which has certain drawbacks. To address this, we propose a weft straightening device for a weft knitting circular knitting machine. Utility Model Content

[0005] The purpose of this invention is to provide a weft straightening device for a circular knitting machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a weft straightening device for a weft knitting circular knitting machine, comprising a worktable and a vertical plate fixed to the top of the worktable, an mounting plate mounted on the vertical plate, a weft skew image detector disposed at the bottom of the mounting plate, a flexible weft straightening roller disposed at the top of the worktable, a driving device for driving the flexible weft straightening roller disposed on the worktable, an installation component for disassembling and assembling the mounting plate disposed on the vertical plate, and a locking component for restricting the installation component disposed on the back of the vertical plate; The positioning component includes: The ring-shaped retaining teeth are used to engage with the opposing retaining teeth to restrict the installation of components; The sleeve is used to control the separation of the contact teeth and the annular teeth via the support rod; The fixing rod is used to support the abutting teeth; A stop spring is used to control the repositioning of the stop teeth when no external force is applied.

[0007] Preferably, the mounting assembly includes a slot located at the top of the vertical plate. A fixing post is fixed to the bottom of the mounting plate, and an insertion hole is provided on the side of the fixing post. A fixing plate is fixed to the inner wall of the vertical plate. An elastic telescopic rod is fixed to the side of the fixing plate near the fixing post. The end of the elastic telescopic rod away from the fixing plate is fixed to an insertion block. The insertion block is inserted into the insertion hole. A pull rope is fixed to the side of the insertion block near the fixing plate. The end of the pull rope away from the insertion block passes through the fixing plate and is fixed to the outer wall of the rotating rod. The rotating rod passes through the vertical plate and is rotatably connected to the vertical plate. When disassembling the mounting plate and the latitudinal oblique image detector, simply rotate the rotating rod. The rotating rod can then pull the insertion block out of the insertion hole by winding the pull rope, thereby releasing the restriction on the fixing post. At this time, the fixing post can be pulled out of the slot, thus disassembling the mounting plate and the latitudinal oblique image detector. During installation, after the fixing post is inserted into the slot, the insertion block is controlled to insert into the insertion hole to restrict the fixing post, thereby completing the installation of the mounting plate.

[0008] Preferably, the annular retaining tooth is fixed to the back of the vertical plate, the rotating rod passes through the sleeve and is slidably connected to the sleeve, a return spring is fixed on the inner wall of the sleeve, the end of the return spring away from the sleeve is fixed to the rotating rod, the fixing rod is fixed to the outer wall of the rotating rod, the fixing rod passes through the abutting retaining tooth and is slidably connected to the abutting retaining tooth, an abutting spring is fixed on the side of the abutting retaining tooth near the rotating rod, the end of the abutting spring away from the abutting retaining tooth is fixed to the fixing rod, a support rod is hinged to the side of the sleeve near the vertical plate, the end of the support rod away from the sleeve is hinged to the abutting retaining tooth, and the abutting retaining tooth connects to the annular retaining tooth. The interlocking teeth restrict the rotation of the rod. When the rod needs to be rotated, simply pull the sleeve away from the vertical plate. The sleeve, through the support rod, pulls the contact teeth and the annular teeth to disengage, thus releasing the restriction on the rod. At this point, simply rotating the sleeve will drive the rod to rotate. After the control block is removed from the insertion hole, simply push the sleeve back to reset it, causing the contact teeth to re-engage with the annular teeth, thereby re-restricting the rod. No operator needs to constantly hold the rod, and the mounting plate and latitudinal oblique image detector can then be disassembled. This system is easy to operate and use by a single person.

[0009] Preferably, the driving device includes a servo motor, which is fixed to the front of the mounting frame. The mounting frame is fixed to the bottom of the worktable. The output shaft of the servo motor passes through the mounting frame and is fixed to a screw. The screw is threadedly connected to a nut, and the nut is fixed to a bracket. The bracket passes through the worktable and is slidably connected to the worktable. The flexible weft straightening roller is rotatably mounted on the inner side of the bracket. A control panel is provided on the top of the worktable. The control panel is electrically connected to both the servo motor and the weft skew image detector. By driving the screw to rotate through the servo motor, the nut can be controlled to move along with the bracket, thereby controlling the movement of the flexible weft straightening roller. The flexible weft straightening roller rolls on the fabric surface to straighten the weft.

[0010] Compared with the prior art, this utility model provides a weft straightening device for a weft knitting circular knitting machine, which has the following beneficial effects: This weft knitting circular knitting machine uses a weft straightening device. Through the installation and locking components, when the rotating rod needs to be rotated, simply pull the sleeve to the side away from the vertical plate. The sleeve, through the support rod, pulls the contact teeth and the annular teeth to disengage, thus releasing the restriction on the rotating rod. At this time, simply rotating the sleeve will drive the rotating rod to rotate. After the control block is removed from the insertion hole, simply push the sleeve back to reset, so that the contact teeth re-engage with the annular teeth, thus re-restricting the rotating rod. There is no need for the operator to hold it constantly. At this time, the installation plate and weft skew image detector can be disassembled. It is easy to operate by a single person.

[0013] like Figures 1-7 As shown, this utility model provides a technical solution: a weft straightening device for a weft knitting circular knitting machine, including a worktable 1 and a vertical plate 2 fixed on the top of the worktable 1. An mounting plate 5 is installed on the vertical plate 2, and a weft skew image detector 6 is provided at the bottom of the mounting plate 5. A flexible weft straightening roller 7 is provided on the top of the worktable 1, and a driving device for driving the flexible weft straightening roller 7 is provided on the worktable 1. An installation component 3 for assembling and disassembling the mounting plate 5 is provided on the vertical plate 2. A locking component 4 for restricting the installation component 3 is provided on the back of the vertical plate 2. The locking component 4 includes: annular locking teeth 41, abutting locking teeth 42, a sleeve 43, a support rod 44, a fixing rod 45, an abutting spring 46, and a return spring 47.

[0014] Mounting assembly 3 includes a slot 31 located at the top of the vertical plate 2. A fixing post 32 is fixed to the bottom of the mounting plate 5. An insertion hole 33 is provided on the side of the fixing post 32. A fixing plate 34 is fixed to the inner wall of the vertical plate 2. An elastic telescopic rod 35 is fixed to the side of the fixing plate 34 near the fixing post 32. The end of the elastic telescopic rod 35 away from the fixing plate 34 is fixed to a plug 36. The plug 36 is inserted into the insertion hole 33. A pull rope 37 is fixed to the side of the plug 36 near the fixing plate 34. The end of the pull rope 37 away from the plug 36 passes through the fixing plate 34 and is fixed to the outer wall of a rotating rod 38. The rotating rod 38 passes through the vertical plate 2 and is rotatably connected to it. The elastic telescopic rod 35 is an extension... The simple assembly of the telescopic rod and spring serves to support the insert block 36 while allowing it to reset under the action of the elastic telescopic rod 35 when it is not pulled. When disassembling the mounting plate 5 and the latitudinal image detector 6, simply rotate the rotating rod 38. The rotating rod 38 can then pull the insert block 36 out of the insertion hole 33 via the winding rope 37, thereby releasing the restriction on the fixing post 32. At this point, the fixing post 32 can be pulled out of the slot 31, thus disassembling the mounting plate 5 and the latitudinal image detector 6. During installation, after inserting the fixing post 32 into the slot 31, the insert block 36 is inserted into the insertion hole 33 to restrict the fixing post 32, thereby completing the installation of the mounting plate 5.

[0015] An annular retaining tooth 41 is fixed to the back of the vertical plate 2. A rotating rod 38 passes through a sleeve 43 and is slidably connected to the sleeve 43. A return spring 47 is fixed on the inner wall of the sleeve 43. The end of the return spring 47 away from the sleeve 43 is fixed to the rotating rod 38. A fixing rod 45 is fixed to the outer wall of the rotating rod 38. The fixing rod 45 passes through a contact retaining tooth 42 and is slidably connected to the contact retaining tooth 42. A contact spring 46 is fixed on the side of the contact retaining tooth 42 near the rotating rod 38. The end of the contact spring 46 away from the contact retaining tooth 42 is fixed to the fixing rod 45. A support rod 44 is hinged to the side of the sleeve 43 near the vertical plate 2. The end of the support rod 44 away from the sleeve 43 is hinged to the contact retaining tooth 42. The contact retaining tooth 42 and the annular retaining tooth are connected. 41 interlocks to restrict the rotating rod 38. When the rotating rod 38 needs to be rotated, simply pull the sleeve 43 to move it away from the vertical plate 2. The sleeve 43 pulls the contact tooth 42 and the annular tooth 41 out of the interlocking state through the support rod 44, thereby releasing the restriction on the rotating rod 38. At this time, simply rotate the sleeve 43 to drive the rotating rod 38 to rotate. After the control plug 36 is removed from the plug hole 33, simply push the sleeve 43 to reset, so that the contact tooth 42 re-interlocks with the annular tooth 41, thereby re-restricting the rotating rod 38. There is no need for the staff to hold it all the time. At this time, the mounting plate 5 and the latitudinal oblique image detector 6 can be disassembled. It is easy to operate and use by a single person.

[0016] The driving device includes a servo motor 8, which is fixed to the front of a mounting frame 9. The mounting frame 9 is fixed to the bottom of a worktable 1. The output shaft of the servo motor 8 passes through the mounting frame 9 and is fixed to a screw 10. The screw 10 is threadedly connected to a nut 11, and the nut 11 is fixed to a bracket 12. The bracket 12 passes through the worktable 1 and is slidably connected to it. A flexible weft straightening roller 7 is rotatably mounted on the inside of the bracket 12. A control panel 13 is provided on the top of the worktable 1. The control panel 13 is electrically connected to both the servo motor 8 and the weft skew image detector 6. By driving the screw 10 to rotate through the servo motor 8, the nut 11 can be controlled to move along with the bracket 12, thereby controlling the movement of the flexible weft straightening roller 7. The flexible weft straightening roller 7 rolls on the fabric surface to straighten the weft. The control panel 13 is used to control the servo motor 8 and the weft skew image detector 6. This is prior art in the field, so its internal structure will not be described in detail here.

[0017] When it is necessary to disassemble the latitudinal oblique image detector 6, pull the sleeve 43 to move it away from the vertical plate 2. The sleeve 43 pulls the contact tooth 42 and the annular tooth 41 out of the engagement state through the support rod 44, thereby releasing the restriction on the rotating rod 38. At this time, simply rotate the sleeve 43 to drive the rotating rod 38 to rotate. The rotating rod 38 can then pull the insert block 36 out of the insertion hole 33 through the winding rope 37, thereby releasing the restriction on the fixed column 32. After the control insert block 36 is released from the insertion hole 33, simply push the sleeve 43 to reset, so that the contact tooth 42 re-engages with the annular tooth 41, thereby re-restricting the rotating rod 38. At this time, the staff can remove the mounting plate 5 and the latitudinal oblique image detector 6.

[0018] During installation, simply reinsert the fixing post 32 into the slot 31, pull the sleeve 43 again and rotate it in the opposite direction. The insert block 36 will no longer be pulled by the pull rope 37. Under the action of the elastic telescopic rod 35, the insert block 36 will reset and be inserted into the insertion hole 33, thus restricting the fixing post 32 and completing the installation.

[0019] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
