Description

Technical Field

[0001] The invention relates to a bottom raising device of a flat knitting machine, in particular to a bottom raising device for synchronous belt yarn pumping. Background Art

[0002] The bottoming device of a flat knitting machine mainly includes a threading mechanism and a wire winding mechanism, wherein the wire winding mechanism feeds out the steel wire during bottoming, so that the steel wire passes through each bottoming coil and pulls the bottoming coil to realize bottom weaving; after the bottoming is completed, the wire winding mechanism withdraws the steel wire so that the steel wire exits from each bottoming coil. The wire winding mechanism in the prior art mainly consists of a wire feeding base plate, a wire winding disk and a wire guide wheel. For example, the structure adopted by the "wire winding device" disclosed in the invention patent with announcement number CN220977313U, the steel wire is wound on the wire winding disk, and the steel wire is clamped by the relatively arranged wire guide wheels to realize the extraction of the steel wire. This scheme is also the structure commonly adopted by the wire winding mechanism in the current prior art, but this structural layout is slightly complicated, and the installation accuracy requirements for the wire guide wheels are high, the manufacturing cost is difficult to reduce, and the steel wire is repeatedly rubbed and squeezed, which also affects its service life.

[0003] To reduce manufacturing costs and increase the service life of steel wire, some designers have adopted a belt-pressed wire feeding method to replace the aforementioned wire-grip-clamped wire feeding method. For example, patents CN219490310U and CN115897041A both employ a belt-pressed wire feeding structure. However, both patents have the following common drawbacks:

[0004] (1) The steel wire is wound on a wire reel, and the wire drawing and feeding are completed by rotating the wire reel in different directions. During this process, the steel wire is repeatedly retracted and released, and is prone to deformation and bending, which increases the friction when the steel wire passes through the needle eye, thereby accelerating the wear of the needle eye and the steel wire, which has a significant impact on the life of the steel wire.

[0005] (2) In the above patent, the motor drives the wire winding disc to rotate, and the wire winding disc drives the belt to move synchronously. Since the wire winding disc needs to store steel wire, a gear disc needs to be provided on the wire winding disc to engage with the gear on the motor. This results in the gear disc on the wire winding disc needing to be made relatively thin within the limited installation space. As a result, the contact area between the gear on the motor and the gear disc on the wire winding disc is very small, which will reduce the service life of the gear.

[0006] (3) Based on the structures in (1) and (2) above, the steel wire is drawn and fed by the extrusion of the belt and the winding drum. Since the steel wire is wound and stored on the winding drum, the end of the steel wire needs to be fixed on the winding drum. According to the transmission method in (2) above, at the moment of feeding the wire, the winding drum rotates first, and then the belt is rotated by the winding drum. Under the influence of inertia, the winding drum and the belt will produce relative displacement at the moment of starting. Since the end of the steel wire is fixed, the steel wire will be stressed during this process. At the same time, when the belt transmission resistance is large, the steel wire will also be stressed due to the asynchrony between the winding drum and the belt. Therefore, the steel wire of this transmission structure is prone to breakage at the fixed end.

[0007] (4) Regarding the monitoring of whether the steel wire has been completely drawn, the above patents all control it through sensors, that is, it is mainly achieved by the cooperation of the spiral groove, the slider assembly and the sensor. This monitoring mechanism needs to have a high sensing accuracy, and high sensing accuracy requires a smaller matching gap to ensure it. Therefore, this structural design increases the processing difficulty to a certain extent. Summary of the Invention

[0008] The bottoming device disclosed in the present invention also adopts a synchronous belt pressing method to realize wire feeding, but the structure designed by the present invention does not need to be stored on the wire loading disk, and will not be deformed or bent.

[0040] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0041] This embodiment discloses a bottoming device for a knitting machine, wherein the winding mechanism in the bottoming device realizes the drawing and feeding of the steel wire by means of synchronous belt pressing. Figure 1 As shown ( Figure 1 The outer cover of the winding mechanism 3 has been removed in the figure). The bottoming device mainly includes a threading plate 1 and a winding mechanism 3. The threading plate 1 is assembled from multiple threading unit plates. Figure 1 From left to right, the following are the threading unit board C1, two threading unit boards B1, and threading unit board A1. A lead plate is assembled on one side of threading unit board A1. The wire winding mechanism 3 is fixedly mounted below the threading unit board 1, near the side of threading unit board A1. This embodiment primarily improves the structure of the wire winding mechanism 3 and the detection mechanism 5, which are described in detail below with reference to the accompanying drawings.

[0042] like Figure 3 and Figure 4 As shown, the wire winding mechanism 3 mainly includes a wire feeding base plate 31, and a wire loading disc 32 is installed in the middle of the front of the wire feeding base plate 31. The structure of the wire loading disc 32 is as shown in FIG. Figure 9As shown, teeth 321 are formed on both sides of the outer circumference of the wire loading disc 32 near the edge, and a wire guide 322 is formed between the teeth 321 on both sides. A plurality of synchronous wheels and a tensioning wheel 34 are set on the front of the wire feeding base plate 31 along the outer circumference of the wire loading disc 32. In this embodiment, Figure 3 The direction shown is for reference only. The wire is fed in the direction of the upper right corner and rotates clockwise along the outer circumference of the wire loading disk 32 from the starting position of the wire feeding end. The first synchronous wheel 33C, the tensioning wheel 34, the driving gear 36, the second synchronous wheel 33B, the third synchronous wheel 33A and the fourth synchronous wheel 33D are arranged in sequence along the outer circumference of the wire loading disk 32. The motor 35 is installed on the back of the wire feeding base plate 31 so that the output shaft of the motor 35 extends out of the front of the wire feeding base plate 31, and the driving gear 36 is installed at the end of the output shaft of the motor 35. The synchronous belt 37 with teeth and a closed shape is wound around the outer circumference of each of the above-mentioned synchronous wheels and the tensioning wheel 34 in sequence. At this time, the wire loading disk 32 is located outside the annular closed area surrounded by the synchronous belt 37 (see Figure 4 ), so that the synchronous belt 37 is engaged with the outer circumferential tooth portion 321 of the wire loading disk 32. In this embodiment, the motor 35 is used to drive the driving gear 36 to rotate, and the driving gear 36 drives the synchronous belt 37 to rotate, and the synchronous belt 37 drives the wire loading disk 32 to rotate.

[0043] Continuing with the above introduction, a tube fixing seat 38 is fixed on the front side of the wire feeding base plate 31 and on the right side of the chassis 32. The top surface of the tube fixing seat 38 is provided with an embedding groove along the wire feeding direction and an alarm spring 39 is installed. The wire guide tube 6 is fixed in the embedding groove. When the steel wire is fed, it passes through the alarm spring 36 along the wire guide tube 6 and then is fed.

[0044] The wire loading disc 32 in this embodiment only plays the role of pumping the steel wire, and the steel wire does not need to be wound and stored on the wire loading disc 32. Therefore, this embodiment also provides a long wire threading tube 2 for accommodating the steel wire and having a natural curvature. Figure 3 As shown, the head end of the wire threading tube 2 is fixed on the tube fixing seat 38, and the head end of the wire threading tube 2 is close to the wire loading disc 32 and the fourth synchronous wheel 33D. Figure 2 As shown, the tail end of the wire threading tube 2 is fixed to the back of the threading plate 1 near the threading unit plate C1, and a detection mechanism 5 is installed on one side of the tail end of the wire threading tube 2. The wire threading tube 2 is also fixed to the back of the wire feeding base plate 31 between the head and tail ends through the tube buckle seat 4, so that the wire threading tube 2 can be in a naturally curved shape. After the above structure is set, the steel wire only needs to be wound along the wire guide portion 322 of the wire loading disk 32 in a small section, so that it is clamped by the synchronous belt 37 and the wire loading disk 32 to realize wire drawing and wire feeding. The wire outlet end of the steel wire is passed through the wire guide tube 6, and the remaining steel wire after being wound along the wire guide portion 322 of the wire loading disk 32 is passed through the wire threading tube 2.

[0045] The adjustment structure of the tensioning wheel 34 is set as follows Figure 5 As shown, an adjustment slot 343 is provided on the wire feeding base plate 31, and a fixing block 341 and an adjustment rod 342 are provided on the back of the wire feeding base plate 31. The fixing block 341 is fixed to the back of the wire feeding base plate 31 by bolts, and a through hole is provided on the fixing block 341, so that the adjustment rod 342 passes through the through hole and the adjustment rod 342 can move relatively along the through hole. To prevent the adjustment rod 342 from falling off the fixing block 341, a limit block 344 and a limit block 345 are provided at both ends of the adjustment rod 342, so that the limit block 345 is connected to the bottom of the rotating shaft of the tensioning wheel 34. When the tension of the tensioning wheel 34 needs to be adjusted, the position of the tensioning wheel 34 relative to the adjustment slot 343 can be adjusted by pulling the adjustment rod 342. After the position is adjusted, the adjustment rod 343 can be locked by the adjustment nut to prevent it from moving.

[0046] The detection mechanism 5 used in this embodiment to monitor whether the wire drawing is completed is much simpler in structure and easier to install than the magnetic sensor method used in the prior art. Figure 6 As shown, it is mainly composed of a sensing base 51 and a sensing sheet 52. The structure of the sensing base 51 is as follows Figure 7 As shown, the body 511 of the induction base 51 can be divided into a wire threading tube fixing portion 513 and a sensor plate fixing portion 512. The wire threading tube fixing portion 513 is provided with a fixing hole 519. The induction base 51 is fixed to the back of the threading plate 1 by passing a bolt through the fixing hole 519. The wire threading tube fixing portion 513 is connected to the sensor plate fixing portion 512 and a gap is provided between the two. The side wall of the wire threading tube fixing portion 513 facing the sensor plate fixing portion 512 is provided with an upper groove 517 and a lower groove 516. A pipe hole 515 is provided between the upper groove 517 and the lower groove 516. The wire threading tube fixing portion 513 is provided with a clearance groove from the top surface downward, and the clearance groove is mutually connected with the upper groove 517 and the pipe hole 515. The top surface of the connecting section between the wire threading tube fixing portion 513 and the sensor plate fixing portion 512 is an inclined surface 514, and a fixing hole 518 is provided on the top surface of the sensor plate fixing portion 512. The structure of the sensor plate 52 is as follows: Figure 8 As shown, the sensing sheet 52 is a sheet structure formed by bending, and the sensing sheet 52 is composed of a first connecting sheet 521, a second connecting sheet 522 and a third connecting sheet 523 connected end to end in sequence, wherein the second connecting sheet 522 and the third connecting sheet 523 are both located at the lower part of the first connecting sheet 521, the second connecting sheet 522 is parallel to the first connecting sheet 521 and fits each other, and the third connecting sheet 523 is inclined downward relative to the first connecting sheet 521, and a through fixing hole 521 is opened in the fitting part of the first connecting sheet 521 and the second connecting sheet 522.

[0047] The assembly method of the sensor base 51 and the sensor sheet 52 is as follows Figure 6As shown, the sensing piece 52 is installed on the sensing piece fixing portion 512 of the sensing base 51, so that the end of the first connecting piece 521 is embedded in the upper groove 517, the third connecting piece 523 is fitted into the inclined surface 514, and the end of the third connecting piece 523 is inserted into the lower groove 516, and the sensing piece 52 is fixed with bolts passing through the fixing holes 524 and the fixing holes 518, and the tail end of the wire tube 2 is inserted into the tube hole 515 from the outside of the sensing base 51 and fixed.

[0048] The process of the wire winding mechanism 3 of the present invention to realize the wire drawing is described as follows: Figure 3 The shown direction is for reference. When the output shaft of the motor 35 drives the driving gear 36 to rotate in the counterclockwise direction, the synchronous belt 37 rotates in the clockwise direction, and the wire loading disc 32 rotates in the counterclockwise direction. The steel wire continuously extends from the wire threading tube 2 and starts to be fed along the wire guide tube 6 under the clamping of the synchronous belt 37 and the wire loading disc 32; when the output shaft of the motor 35 drives the driving gear 36 to rotate in the clockwise direction, the synchronous belt 37 rotates in the counterclockwise direction, and the wire loading disc 32 rotates in the clockwise direction, and the steel wire is continuously fed back into the wire threading tube 2. Once the tail end of the steel wire extends from the wire threading tube 2 near one end of the sensing seat 51, when the tail end of the extended steel wire touches the third connecting piece 523 of the sensing piece 52, the sensing piece 52 will feedback a detection signal to the control system. After the control system receives the detection signal, it indicates that the steel wire has completed the wire drawing process, and the motor 35 can be stopped.

[0049] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
