Description

Technical Field

[0001] The present invention relates to the technical field of flat knitting machine accessories, and particularly relates to a dynamic brush mechanism for a double-system flat knitting machine. Background Art

[0002] Among flat knitting machines, the double-system flat knitting machines with various needle types have the largest inventory. The existing brush technology structure on double-system flat knitting machines: needle plates for installing knitting needles are symmetrically arranged on a base. Above the needle plates is a machine head aluminum cover. A sinker is arranged at the front of the aluminum cover. There is a sinker cover above the sinker. A brush holder is fixedly installed on the sinker cover by screws. A brush fixing block is installed on the brush holder. A brush is installed on the brush fixing block by a brush clip. After the brush is installed, its position is fixed relative to the aluminum cover.

[0003] During the processing of knitted sweaters, knitting needles are components with extremely high wear. Since the position of the brush is fixed relative to the aluminum cover during the needle turning process, the brushing damage to the needle tongues of the knitting needles by the brush is an uncontrollable process, which greatly affects the service life of the knitting needles. In view of the above problems, a solution is proposed as follows. Summary of the Invention

[0004] The purpose of the present invention is to provide a dynamic brush mechanism for a double-system flat knitting machine, which has the advantage of high service life of knitting needles.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions:

[0006] A dynamic brush mechanism for a double-system flat knitting machine includes two machine head aluminum covers. A plurality of bottom plate mounting blocks and a plurality of sinker mounting seats are fixedly installed on each of the machine head aluminum covers by bolts. A sinker is fixedly installed on one side of a plurality of the sinker mounting seats by bolts. A bottom plate is fixedly installed on one side of a plurality of the bottom plate mounting blocks by bolts, and the bottom plate is located above the front part of the machine head aluminum cover. Two rotating shaft seats are installed on one side of the bottom plate. A rotatable rotating shaft is penetrated through the two rotating shaft seats. A rotating assembly is arranged above the machine head aluminum cover, and the rotating assembly is connected to the rotating shaft to drive the rotating shaft to rotate. Two cams are installed on the rotating shaft. Two rotating seat positioning blocks are fixedly arranged on one side of the bottom plate. A rotating seat is arranged on the rotating seat positioning block. Two pin shafts are penetrated through the rotating seat. The rotating seat positioning block and the rotating seat are rotationally connected by the pin shafts. A torsion spring is installed on the pin shaft. A roller is arranged on the rotating seat. One end of another pin shaft penetrates through the roller and is rotationally connected to the roller. The two rollers are respectively matched with the cams. A left dynamic brush mechanism and a right dynamic brush mechanism are symmetrically arranged above the machine head aluminum cover, and the left dynamic brush mechanism and the right dynamic brush mechanism are respectively connected to the two rotating seats.

[0007] Preferably, the left dynamic brush mechanism includes a brush holder, a brush clamp, and a brush assembly. The brush holder is installed on the rotating seat by bolts. The brush clamp is installed inside the brush holder by bolts. The brush assembly is installed at the front end of the brush clamp and is located above the sinker. The structure of the right dynamic brush mechanism is the same as that of the left dynamic brush mechanism.

[0008] Preferably, two high convex points and two low convex points are symmetrically arranged on the cam.

[0009] Preferably, the rotating assembly includes a motor. One end of the bottom plate is fixed with a motor mounting plate by bolts, and the motor is installed on one side of the motor mounting plate. A motor gear is provided on the other side of the motor mounting plate, and the output shaft of the motor is fixedly connected to the motor gear. One end of the rotating shaft is fixedly provided with a transmission gear, and the transmission gear meshes with the motor gear. A retaining ring is fixedly provided at the other end of the rotating shaft.

[0010] Preferably, the left dynamic brush mechanism and the right dynamic brush mechanism can turn the needles individually or simultaneously with the two mechanisms, and the brushes perform the actions of opening or not opening to cooperate with the mechanism for knitting. Therefore, there are four combined working modes for the brushes in the left dynamic brush mechanism and the right dynamic brush mechanism.

[0011] The beneficial effects of the present invention are as follows: The rotating assembly can drive the rotating shaft and the two cams to rotate simultaneously. Under the action of the torsion spring, the rotating seat drives the roller and the cams on the rotating shaft to be closely attached together, and different heights on the cam can drive the rotating seat to stay at different height positions. During the knitting of the flat knitting machine, the left dynamic brush mechanism and the right dynamic brush mechanism can execute the needle turning knitting or the knitting actions other than needle turning according to the pattern instructions, and can turn the needles individually or simultaneously with the two mechanisms. The brushes perform the actions of opening or not opening to cooperate with the mechanism for knitting. There are four combined working modes for the brushes in the two mechanisms. During the loop knitting process, the knitting needles on the needle bed base of the flat knitting machine move upward and the needle tips are inserted into the brushes. The brushes brush open the needle tongues of the needle tips. After the brushes open the needle tongues, at this time, the knitting needles reach the highest point in the loop knitting process. The brushes only brush the needle tips and cannot brush the needle tongues, and the damage to the needle tongues can be ignored. The service life of the knitting needles is not affected by the brushes. During the needle turning knitting process (transferring loops), the needle tongues of the knitting needles do not need to be opened by the brushes. Since the positions of the brushes are fixed, the knitting needles move upward and the needle tips are inserted into the brushes. The brushes brush open the needle tongues of the needle tips. After the brushes open the needle tongues, at this time, the knitting needles reach the highest point in the loop transferring process. The brushes cannot brush the needle tongues and will not cause damage (brush skew) to the needle tongues. Therefore, the service life of the knitting needles will be greatly improved.

[0025] Figure 10 and Figure 11 are the comparative diagrams of the prior art and are used as comparative references in this case.

[0026] As Figures 1 to 7 shown, a double-system flat knitting machine dynamic brush mechanism includes two head aluminum covers 1. A plurality of bottom plate mounting blocks 2 and a plurality of sinker mounting seats 3 are fixed on each head aluminum cover 1 by bolts. A sinker 4 is fixed on one side of the plurality of sinker mounting seats 3 by bolts. A bottom plate 5 is fixed on one side of the plurality of bottom plate mounting blocks 2 by bolts, and the bottom plate 5 is located above the front part of the head aluminum cover 1. Two rotating shaft seats 6 are installed on one side of the bottom plate 5. A rotatable rotating shaft 7 is passed through the two rotating shaft seats 6. A rotating assembly 8 is arranged above the head aluminum cover 1, and the rotating assembly 8 is connected to the rotating shaft 7 to drive the rotating shaft 7 to rotate. Two cams 9 are installed on the rotating shaft 7. The rotating assembly 8 includes a motor. One end of the bottom plate 5 is fixed with a motor mounting plate 22 by bolts, and the motor is installed on one side of the motor mounting plate 22. A motor gear 23 is arranged on the other side of the motor mounting plate 22, and the output shaft of the motor is fixedly connected to the motor gear 23. A transmission gear 24 is fixedly arranged at one end of the rotating shaft 7, and the transmission gear 24 meshes with the motor gear 23. A retaining ring 25 is fixedly arranged at the other end of the rotating shaft 7. By rotating the motor, the motor gear 23 can be driven to rotate. Since the transmission gear 24 meshes with the motor gear 23, the rotation of the motor gear 23 can drive the transmission gear 24 to rotate, and finally the rotation of the rotating shaft 7 and the two cams 9 can be realized simultaneously.

[0027] Two rotating seat positioning blocks 10 are fixedly arranged on one side of the bottom plate 5. A rotating seat 11 is arranged on the rotating seat positioning blocks 10. Two pin shafts 12 are passed through the rotating seat 11, and the rotating seat positioning blocks 10 and the rotating seat 11 are rotationally connected by the pin shafts 12. A torsion spring 13 is installed on the pin shafts 12. A roller 14 is arranged on the rotating seat 11, and one end of another pin shaft 12 passes through the roller 14 and is rotationally connected to the roller 14. The two rollers 14 are respectively matched with the cams 9. Under the action of the torsion spring 13, the rotating seat 11 drives the roller 14 and the cams 9 on the rotating shaft 7 to be closely attached together, and different heights on the cams 9 can drive the rotating seat 11 to stay at different height positions.

[0028] Above the aluminum head cover 1 of the machine head, a left dynamic brush mechanism 15 and a right dynamic brush mechanism 16 are symmetrically arranged, and the left dynamic brush mechanism 15 and the right dynamic brush mechanism 16 are respectively connected to two rotating seats 11. The left dynamic brush mechanism 15 includes a brush holder 17, a brush clip 18 and a brush assembly 19. The brush holder 17 is installed on the rotating seat 11 by bolts, the brush clip 18 is installed on the inner side of the brush holder 17 by bolts, the brush assembly 19 is installed at the front end of the brush clip 18, and the brush assembly 19 is located above the sinker 4. The structure of the right dynamic brush mechanism 16 is the same as that of the left dynamic brush mechanism 15. During the knitting of the flat knitting machine, the left dynamic brush mechanism 15 and the right dynamic brush mechanism 16 can perform purl knitting or knitting actions other than purl knitting according to the pattern instructions. They can purl with a single mechanism or purl simultaneously with two mechanisms. The brush can be opened or not opened to cooperate with the mechanism for knitting. There are four combined working modes for the brushes in the two mechanisms.

[0029] As Figure 8 shown, two high convex points 20 and two low convex points 21 are symmetrically arranged on the cam 9. During the knitting of the flat knitting machine, the flat knitting machine system will perform purl knitting or knitting actions other than purl knitting according to the pattern file. The brush correspondingly has two working states for cooperation. The working state of the brush is for knitting actions other than purl knitting, and the non-working state of the opened brush is for purl knitting actions. The left dynamic brush mechanism 15, the right dynamic brush mechanism 16 and the cam 9 are installed on the rotating shaft 7 with an angular misalignment of 90°. The rotating shaft 7 drives the two cams 9 to rotate simultaneously. There are four combinations of the relative positions of the outer contour of the cam 9 to the roller 14.

[0030] As Figure 9 shown, the left dynamic brush mechanism 15 and the right dynamic brush mechanism 16 can purl with a single mechanism or purl simultaneously with two mechanisms, and the brush can be opened or not opened to cooperate with the mechanism for knitting. Therefore, there are four combined working modes for the brushes in the left dynamic brush mechanism 15 and the right dynamic brush mechanism 16. During the loop knitting process, the knitting needles on the needle bed base of the flat knitting machine move upward and the needle tips are inserted into the brush. The brush brushes open the needle tongues of the needle tips. After the brush opens the needle tongues, at this time, the knitting needles reach the highest point in the loop knitting process. The brush only brushes the needle tips and cannot brush the needle tongues, and the damage to the needle tongues can be ignored. The service life of the knitting needles is not affected by the brush. During the purl knitting process (transfer of loops), the needle tongues of the knitting needles do not need to be opened by the brush. Since the position of the brush is fixed, the knitting needles move upward and the needle tips are inserted into the brush. The brush brushes open the needle tongues of the needle tips. After the brush opens the needle tongues, at this time, the knitting needles reach the highest point in the transfer of loops knitting process. The brush cannot brush the needle tongues and will not cause damage (brush crooked) to the needle tongues. Therefore, the service life of the knitting needles will be greatly improved.

[0031] In the specific embodiments described above, the technical problems solved by the present invention, the technical solutions and the beneficial effects have been further described in detail. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
