AI Technical Summary
In existing circular knitting machines, the wax block contacts the yarn at a fixed position, resulting in low wax block utilization and easy breakage, making it impossible to apply wax evenly.
The design employs a roller-type wax block and mounting frame, allowing the wax block to move perpendicular to the yarn's direction of movement. The mounting frame reciprocates via a moving component, and combined with a tensioning and disassembly component, the contact position between the wax block and the yarn can be varied, thus improving utilization.
The wax block wear is more uniform, which improves the utilization rate of the wax block, simplifies the wax block replacement process, and extends the service life of the wax block.

Abstract
Description
Technical Field
[0001] This application relates to the field of large circular knitting machines, and more particularly to a waxing device for large circular knitting machines. Background Technology
[0002] The development of polyester-spandex blended single-sided knitted high-elasticity fabrics requires combining the performance advantages of polyester (polyester fiber) and spandex (polyurethane elastic fiber). High elasticity, comfort and durability are achieved through process optimization and structural design. Knitting is often carried out using single-sided knitting circular knitting machines.
[0003] Currently, Chinese utility model patent CN204980652U discloses a waxing device for a circular knitting machine, including a bracket with a mounting groove on its upper part. The mounting groove has a yarn inlet and a yarn outlet on its two side walls, and a tension device is installed within the mounting groove. It also includes a first waxing seat and a second waxing seat, both arranged within the mounting groove, along the yarn conveying direction. The first and second waxing seats each have a first thread guide groove and a second thread guide groove, respectively. A waxing block is installed in the first thread guide groove, positioned above and in contact with the yarn. A lower waxing block is installed in the second thread guide groove, positioned below and in contact with the yarn. This application achieves the effect of uniformly waxing the yarn.
[0004] As the yarn moves, it moves relative to the wax block, and some of the wax block adheres to the yarn, achieving the effect of waxing the yarn. However, over time, indentations will appear at the contact point between the wax block and the yarn. Since the contact point between the wax block and the yarn remains unchanged, the wax block eventually breaks in the middle, requiring timely replacement. In reality, the utilization rate of the wax block for waxing the yarn is low. Utility Model Content
[0005] In order to improve the utilization rate of wax blocks during waxing, this application provides a waxing device for a large circular knitting machine.
[0006] This application provides a waxing device for a large circular knitting machine, which adopts the following technical solution:
[0007] A waxing device for a circular knitting machine includes a bracket and a waxing assembly. The waxing assembly includes a mounting frame, two wax blocks, and a movable component. The mounting frame is slidably connected to the bracket along a direction perpendicular to the movement of the yarn. The two wax blocks are roller-shaped and rotatably connected to the mounting frame. The yarn abuts against the sidewalls of the two wax blocks respectively. The movable component is used to drive the mounting frame to reciprocate.
[0008] By adopting the above technical solution, the yarn will come into contact with two wax blocks during the movement, so that the yarn is waxed on all sides. The mounting frame can move on the support along the direction perpendicular to the movement of the yarn, so that the contact position between the yarn and the wax block will always change, so that all parts of the wax block can wax the yarn, making the wax block wear more uniform and thus improving the utilization rate of the wax block.
[0009] Optionally, the mounting frame is provided with a tensioning element, which includes a tensioning frame and a torsion spring. The tensioning frame is rotatably connected to the mounting frame along a direction perpendicular to the movement of the yarn. Both wax blocks are rotatably connected to the tensioning frame. The torsion spring is used to keep both wax blocks in contact with the yarn.
[0010] By adopting the above technical solution, the tensioning frame is rotatably connected to the mounting frame, and two wax blocks are rotatably connected to the tensioning frame. A torsion spring keeps the wax blocks pressed against the yarn. As the diameter of the wax blocks decreases, the spring's elasticity causes the tensioning frame to rotate, keeping the wax blocks pressed against the yarn. The tensioning element ensures that the yarn and wax blocks are always taut, resulting in more even waxing of the yarn.
[0011] Optionally, the tensioning frame is provided with a disassembly component for removing the wax block. The disassembly component includes an installation roller and an installation bolt. The installation roller is rotatably connected to the tensioning frame, the wax block is sleeved on the installation roller, and the installation bolt restricts the wax block from detaching from the installation roller.
[0012] By adopting the above technical solution, when the wax block is worn out and can no longer be used, it needs to be replaced. The staff can first unscrew the mounting bolts from the mounting roller, then remove the wax block from the mounting roller, then put the new wax block on the mounting roller, and finally use bolts to prevent the wax block from detaching from the mounting roller.
[0013] Optionally, the disassembly component further includes an abutment piece, which abuts against one end of the wax block away from the tensioning frame, and the tail of the mounting bolt passes through the abutment piece and is threaded onto the mounting roller.
[0014] By adopting the above technical solution, when the wax block is installed on the mounting roller, the abutment piece abuts against the end of the wax block away from the tensioning frame. The area of the abutment piece is larger than the area of the mounting bolt head, which reduces the pressure on the end of the wax block, reduces the deformation of the end of the wax block, and improves the service life of the wax block.
[0015] Optionally, the outer side wall of the mounting roller is provided with a sliding strip, the length direction of the sliding strip is parallel to the length direction of the mounting roller, and the inner side wall of the wax block is provided with a sliding groove that cooperates with the sliding strip.
[0016] By adopting the above technical solution, the sliding strip is used to cooperate with the sliding groove in the wax block, so that the mounting roller can rotate simultaneously with the wax block, thereby realizing that the mounting roller can rotate with the wax block and reducing the wear between the wax block and the mounting roller.
[0017] Optionally, the moving component includes a turntable, a drive motor, a mating rod, and an eccentric rod. The turntable is rotatably connected to the bracket, the eccentric rod is disposed on the turntable, the mating rod is disposed on the mounting frame, and the mating rod has a mating groove parallel to the direction of yarn movement. The eccentric rod is located within the mating groove, and the drive motor is used to drive the turntable to rotate.
[0018] By adopting the above technical solution, when the bracket needs to move back and forth, the staff can start the drive motor, which drives the turntable to rotate. The eccentric rod on the turntable rotates with the turntable. At this time, the eccentric rod slides in the sliding groove of the matching rod. The matching rod drives the mounting frame to move. The movement of the mounting frame changes the contact position between the wax block and the yarn, resulting in more uniform wax block wear.
[0019] Optionally, the bracket is provided with two guide rollers to reduce yarn deviation. The two guide rollers are located on both sides of the waxing assembly, and the guide rollers are hourglass-shaped.
[0020] By adopting the above technical solution, since the wax block moves along the direction perpendicular to the yarn, the wax block will cause the yarn to deviate during the movement of the yarn. The hourglass-shaped guide wheel is used to guide the yarn and reduce the deviation during the movement of the yarn.
[0021] Optionally, the bracket has an inlet hole and an outlet hole on each of the two side walls of the waxing assembly, and the bracket is also provided with a mounting clip for clamping on the large circular knitting machine.
[0022] By adopting the above technical solution, the inlet and outlet holes are used to guide the yarn into the waxing assembly, and the bracket is installed on the circular knitting machine through the mounting clip, which improves the rationality of the equipment.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. The wax blocks are roller-shaped, and the mounting frame for installing the wax blocks can move along the direction of movement perpendicular to the yarn, so as to achieve more uniform wax block wear and improve the utilization rate of wax blocks;
[0025] 2. When the wax block can no longer be used to wax the yarn or the wax block is worn out, the disassembly part is used to remove the wax block from the installation roller, so as to install a new wax block;
[0026] 3. The moving part is used to drive the reciprocating movement of the mounting bracket, thereby achieving uniform wear on the surface of the wax block. Attached Figure Description
