Description

Technical Field

[0001] This utility model relates to the field of knotting machine technology, specifically to a wire guide frame for a knotting machine. Background Technology

[0002] A bartack sewing machine, also known as a bark stitching machine or bark binding machine, is typically used to reinforce stitches. It is generally suitable for manufacturers of clothing, knitwear, sweaters, suits, and denim. The bartack machine reinforces stress points in garments, strengthens the seams of rounded buttonholes, and secures the top of buttonholes. During production, after buttons are attached, workers manually wrap thread around the back of the button several times to reinforce its strength. The bartack machine can automate this process, shortening working time, increasing production efficiency, reducing worker fatigue, and saving labor.

[0003] Currently, the existing wire guide frame of the knotting machine is inconvenient to install, and the wire spool is directly sleeved on the wire spool placement rod. During the wire feeding process, the wire spool is easily pulled by the wire, causing it to detach from the wire spool placement rod, which affects the wire conduction effect. At the same time, the edges of the wire guide holes on the wire guide plate are relatively sharp, which can easily cause friction and cutting to the wire, affecting the quality of the wire. Utility Model Content

[0004] The purpose of this invention is to provide a wire guide frame for a knotting machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire guide frame for a knotting machine, comprising:

[0006] The base plate has first through holes at equal intervals on its upper side, a strong magnetic plate is embedded in the bottom of the base plate, a storage cylinder is fixed to the left end of the base plate, multiple screws are provided at equal intervals on the upper side of the base plate, a wire spool is rotatably sleeved on the bottom of the base plate, and a limit cone is threaded onto the screw.

[0007] The upright plate has its lower end connected to the upper right end of the base plate. A plate sleeve is slidably fitted onto the upright plate. A locking knob is threaded into the right side of the plate sleeve. A guide plate is fixed to the left side of the plate sleeve. An installation hole is opened on the guide plate corresponding to the position directly above each screw. A pair of guide wheels are movably nested in the installation hole.

[0008] Preferably, a second through hole is provided on the strong magnetic plate at the position corresponding to the first through hole.

[0009] Preferably, the tail end of the locking knob abuts against the side wall of the upright plate. By loosening the locking knob, the plate sleeve can be moved up and down to adjust the height of the guide plate, and by tightening the locking knob, the position of the plate sleeve can be fixed.

[0010] Preferably, the inclined sidewall of the limiting cone is provided with multiple grooves at equal intervals, and the bottom edge of the limiting cone is chamfered and rounded to reduce wear on the line. The multiple grooves increase the friction between the hand and the limiting cone, thereby facilitating the rotation of the limiting cone.

[0011] Preferably, a pair of guide wheels are arranged symmetrically, with a rotating shaft fixed on each of the left and right sides of the guide wheels. The end of the rotating shaft away from the guide wheel is rotatably connected to the inner wall of the mounting hole. The two guide wheels guide the line and reduce wear on the line.

[0012] Preferably, the base plate has threaded holes corresponding to the positions of each screw, and the bottom thread of the screw is nested in the threaded hole, which makes the installation between the screw and the base plate simple and convenient, facilitates the replacement of the screw in the future, and facilitates maintenance.

[0013] Preferably, the upper and lower sides of the spool placement tray are provided with limiting collars, which are threaded onto the screw. The two limiting collars limit the position of the spool placement tray, ensuring the stability of the spool placement tray installation.

[0014] Preferably, the limiting cone has a threaded channel that passes through both the upper and lower ends of the limiting cone. The limiting cone is threaded onto the screw through the threaded channel, which makes the installation of the limiting cone simple and facilitates the adjustment of the position of the limiting cone on the screw.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. By opening a first through hole in the base plate and embedding a strong magnetic plate at the bottom of the base plate, the wire guide frame can be fixed to the knotting machine by bolts or adsorbed to the metal shell of the knotting machine by the strong magnetic plate, making the installation of the wire guide frame simple and convenient. The left end of the base plate is provided with a storage tube, which can hold small items such as scissors.

[0017] 2. By setting a limiting cone on the screw, after the spool is sleeved on the screw, the limiting cone is threaded onto the screw to limit the spool and prevent the spool from detaching from the screw under the pull of the wire;

[0018] 3. A pair of guide wheels are rotatably installed in the mounting holes on the guide plate. The two guide wheels guide the wire and reduce wire wear. Attached Figure Description

[0037] In this utility model, a first through hole 2 is provided on the base plate 1, and a strong magnetic plate 3 is embedded in the bottom of the base plate 1, so that the wire guide frame can be fixed to the knotting machine by bolts, or it can be attracted to the metal shell of the knotting machine by the strong magnetic plate 3, making the installation of the wire guide frame simple and convenient. The left end of the base plate 1 is provided with a storage tube 5, which can hold small items such as scissors. After the wire spool is sleeved on the screw 6, the limiting cone 8 is threaded onto the screw 6 to limit the wire spool and prevent the wire spool from detaching from the screw 6 under the pull of the wire. A pair of guide wheels 14 are rotatably installed in the mounting hole 13 on the wire guide plate 12. The two guide wheels 14 guide the wire and reduce the wear of the wire.

[0038] like Figure 1 , Figure 2 and Figure 4 As shown, threaded holes 16 are provided on the base plate 1 corresponding to the positions of each screw 6. The bottom thread of the screw 6 is nested in the threaded hole 16, which makes the installation between the screw 6 and the base plate 1 simple and convenient, and facilitates the replacement of the screw 6 in the future and makes maintenance convenient.

[0039] The upper and lower sides of the spool placement tray 7 are provided with limiting collars 17. The limiting collars 17 are threaded onto the screw 6. The position of the spool placement tray 7 is limited by the two limiting collars 17 to ensure the stability of the spool placement tray 7 during installation.

[0040] In this utility model, the screw 6 and the base plate 1 are connected by threads, which makes the connection between the screw 6 and the base plate 1 simple and convenient to remove the screw 6 from the base plate 1. The spool placement tray 7 is installed on the screw 6 by two limiting collars 17. The limiting collars 17 are threadedly connected to the screw 6, which is simple and convenient for future maintenance and replacement of the screw 6 or the spool placement tray 7.
