Description

Technical Field

[0001] The invention relates to the technical field of crochet machines, in particular to a crochet machine which is convenient for adjusting the length of feather yarns. Background Art

[0002] As we all know, in the textile industry, feather yarn is widely used in clothing, household items, handicrafts and other fields. The weaving process of feather yarn needs to rely on professional crochet machines. Traditional crochet machines usually have the problem of inconvenient adjustment of the length of feather yarn when weaving feather yarn. Feather yarn is composed of warp and weft. The crochet machine makes the weft interweave back and forth between two sets of warp yarns, and then separates the weft yarns between the two sets of warp yarns with a blade. The weft yarn stands upright on the warp yarn to become feathers. The length of the feather depends on the spacing between the two sets of warp yarns.

[0003] After searching, a Chinese patent disclosed a high-speed feather yarn crochet machine, and its application publication number is CN218291270U. This patent can drive the outer wire guide roller to rotate at a high speed by setting a first linkage motor, a rotating rod and a rotating shaft. By setting an oil inlet and a lubrication chamber, lubricating oil can be added to the rotating shaft regularly, thereby increasing the efficiency of the rotating shaft during rotation and ensuring the high-speed rotation of the entire wire guide roller.

[0004] When a crochet machine is making feather yarn, the length of the feather depends on the spacing between two groups of warp yarns fed into the crochet machine. The problems with the prior art are: the prior crochet machine is not convenient for adjusting the spacing between the two groups of warp yarns fed into the crochet machine, resulting in the difficulty in adjusting the feather length of the feather yarn. At the same time, there is a problem that the spacing between multiple groups of warp yarns cannot be adjusted synchronously. Summary of the invention

[0083] Two limiting grooves 65 are formed on the side wall of the U-shaped frame 4, and the limiting blocks 64 are movably connected to the limiting grooves 65; and

[0084] The synchronous drive assembly 66 disposed on the top of the mounting plate 3, when in use, is hingedly coordinated with the two synchronous bars 63. When the synchronous bar 63 is hingedly moved, the limiting block 64 squeezes the limiting groove 65, so that the two ends of the synchronous bar 63 push the two U-shaped frames 4 to move synchronously away from or close to each other, so that the spacing between the two U-shaped frames 4 is synchronously adjusted, and the movement of the U-shaped frame 4 adjusts the spacing between the two wire wheels 5, thereby adjusting the spacing between the two groups of yarns being transported.

[0092] The movable adjustment component 6610 arranged at both ends of the driving rack 669 can, when in use, enable multiple driving gears 668 to rotate synchronously through the driving rack 669, so that multiple driving wheels 665 can rotate synchronously. The driving wheel 665 rotates because its two ends are provided with protrusions. The driving wheel 665 can squeeze the two driving bars 663 to move, and the supporting spring 667 supports the driving bar 663. This process can synchronously drive the two U-shaped frames 4 to realize the adjustment movement, so as to realize the synchronous adjustment movement of the distance between the two groups of two U-shaped frames 4.

[0093] The mobile adjustment component 6610 includes:

[0094] An adjusting screw 66101 fixedly connected to both ends of the driving rack 669, and the adjusting screw 66101 is movably connected to the mounting plate 3; and

[0095] The adjusting threaded sleeve 66102 is threadedly connected to one end of the adjusting screw 66101, and the side wall of the adjusting threaded sleeve 66102 is in contact with the mounting plate 3. When in use, the adjusting threaded sleeve 66102 is rotated away from the adjusting screw 66101, and the movement of the adjusting screw 66101 is pulled to make the driving rack 669 engage with the driving gear 668, so that the multiple driving gears 668 move synchronously. After the adjustment is completed, the two adjusting threaded sleeves 66102 are rotated to move with the adjusting screw 66101, so that the adjusting threaded sleeve 66102 is in contact with the mounting plate 3, and the driving rack 669 is limited at this time.

[0096] Wherein, the height adjustment component 9 comprises:

[0097] A top frame 91 fixedly connected to the top of the support frame 2; and

[0098] Two sets of electric push rods 92 are installed on the top of the top frame 91, and the output ends of the electric push rods 92 are fixedly connected to the mounting plate 3. When in use, the electric push rods 92 move the mounting plate 3 back to adjust the height of the mounting plate 3, thereby adjusting the conveying height of the warp.

[0099] Among them, a plurality of support blocks 10 are arranged on the top of the mounting plate 3 , and the support blocks 10 are movably connected to the driving rack 669 . When in use, the support blocks 10 support the driving rack 669 .

[0100] Among them, a protrusion 11 is fixedly connected to the side wall of the support block 10, and a groove 12 begins to be formed on the side wall of the driving rack 669. The protrusion 11 and the groove 12 are movably connected. When in use, the setting of the protrusion 11 and the groove 12 can realize the limiting movement between the support block 10 and the driving rack 669.

The rotation of the driving wheel 665, due to the protrusions at both ends, the driving wheel 665 can squeeze the two driving strips 663 to move, and the supporting spring 667 supports the driving strip 663. In this process, the two driving strips 663 are connected to the driving wheel 665. The synchronization bar 63 is hingedly coordinated. When the synchronization bar 63 is hingedly moved, the limit block 64 squeezes the limit groove 65, so that the two ends of the synchronization bar 63 push the two U-shaped frames 4 to move synchronously away from or close to each other, so that the distance between the two U-shaped frames 4 is synchronously adjusted. The movement of the U-shaped frame 4 adjusts the distance between the two wire wheels 5, thereby adjusting the distance between the two groups of yarns being transported. After the adjustment of the driving rack 669 is completed, the two adjusting thread sleeves 66102 are rotated to move with the adjusting screw 66101, so that the adjusting thread sleeve 66102 contacts the mounting plate 3, and the driving rack 669 is limited at this time.

In this process, the first thread-sliding surface 73 contacts and slides with the warp thread, and the warp thread passes through the first thread-sliding surface 73 and then enters the interior of the thread-hooking groove 74 through the second thread-sliding surface 75. The hook needle 72 follows the return stroke of the driving cylinder 71, driving the warp thread to move, and the warp thread is made to move in a triangular shape through the two thread-hooking grooves 74 and the wire wheel 5, so that the warp thread can be tensioned and transported.

In this process, the first sliding surface 73 contacts and slides with the warp, and the warp passes through the first sliding surface 73 and then passes through the second sliding surface 75 into the interior of the hook groove 74. The hook needle 72 follows the return stroke of the driving cylinder 71, driving the warp to move. The bottom end of the hook needle 72 is located above the wire wheel 5, and the two hook needles 72 and the wire wheel 5 form a triangular arrangement for the transported warp, so that the warp is tensioned and transported.
