Description

Technical Field

[0001] This utility model relates to a novel spindle tension device for textile machines, belonging to the technical field of spinning frame equipment. Background Technology

[0002] During spinning, the spinning rollers rotate at high speed to tension the spindle belt, which then drives the spindles to work. In ring spinning frames, the spinning rollers are mounted on the main shaft. By increasing surface friction, slippage between the spindle belt and the spinning rollers during power transmission is reduced, significantly decreasing twist unevenness. The spindle belt tensioning device is located between the spinning frame's spinning rollers and the spindle holder, supporting the running spindle belt between them. With the upgrading of the textile industry, users have increasingly higher requirements for textile machinery. Long ring spinning frames with collective doffing have become the mainstream in today's market. In the widely used ring spinning frames, because each spinning roller needs to correspond to one spindle belt tensioning device, multiple spindle belt tensioning devices are required.

[0003] Existing spindle tensioning devices are typically mounted on a tension bar, which in turn is mounted on a central wall plate. The device mainly consists of a spindle tension frame, bearing assembly, tension disc, and counterweight assembly. The tension disc, counterweight assembly, and bearing assembly are mounted on the spindle tension frame. The bearing housing of the bearing assembly is fixedly mounted at the first mounting position on the spindle tension frame, while the bearing is mounted on the tension bar and can rotate relative to it. By controlling the rotation of the spindle tension frame, the tension of the spindle belt on the tension disc is adjusted. However, the tension bar and bearing assembly cannot limit the movement of the spindle tension frame. Therefore, during the operation of the spinning machine, if the spindle belt breaks or falls off, the spindle tension frame may fall or collide with the rollers. Furthermore, this type of tensioning device requires installing the bearing assembly on the tension bar first, then fitting the spindle tension frame onto the bearing housing and securing it with set screws. This necessitates on-site installation of each component, resulting in a large workload and time-consuming and labor-intensive adjustments. Furthermore, the existing weight of the spindle tension device is installed with screws. If the position needs to be adjusted during the debugging process, the screws need to be installed and removed to adjust the position of the weight. The weight is close to the lifting box and the middle wall plate, so the operation is inconvenient. Summary of the Invention

[0004] The purpose of this utility model is to provide a new type of spindle tension device for textile machines that is simple and reasonable in structure, quick to install on the machine, and will not fall or collide with the roller when the spindle belt breaks or falls off.

[0005] Another objective of this invention is to provide a novel spindle tensioning device for textile machines that allows for direct modification of the counterweight installation position.

[0006] The present invention provides a technical solution to achieve the above-mentioned objectives: a novel spindle tension device for textile machines, characterized in that it comprises a spindle tension frame, a tension disc, a counterweight, a tension frame fixing seat, and a tension frame rotary seat; the spindle tension frame has an upper connecting part, an outer counterweight part, and a lower connecting part, the lower connecting part having a limiting groove for positioning and engaging with the tension frame rotary seat; the tension disc is mounted on the upper connecting part of the spindle tension frame via a first fastener; the counterweight is disposed on the counterweight part of the spindle tension frame and is adjustable; the tension frame fixing seat is used to connect the tension rod and the tension frame. The slewing seat, the tension frame fixing seat has a rod hole fitted onto the tension rod and a mounting hole for installing a locking component; the tension frame slewing seat is provided with a mounting groove for accommodating the recess of the tension frame fixing seat and a mounting seat located on one side of the spindle tension frame and connected to the tension frame slewing seat; the limiting groove on the spindle tension frame is set on the mounting seat of the tension frame slewing seat and connected by a second fastener; the tension frame fixing seat is set in the mounting groove of the tension frame slewing seat, and the tension frame slewing seat can rotate along the center of the rod hole of the tension frame fixing seat; the lower parts of the two sides of the tension frame fixing seat are used to limit the rotation position of the tension frame slewing seat.

[0007] Another technical solution of this utility model to achieve the above-mentioned objective is: the spindle tension frame is provided with a plurality of arc-shaped limiting grooves or V-shaped limiting grooves for adjusting the tension of the spindle belt at the counterweight part, and the upper part of the counterweight has an opening and a hanging rod at the top, and the hanging rod is hung in the corresponding arc-shaped limiting groove or V-shaped limiting groove.

[0008] This invention employs a tension frame fixing seat and a tension frame rotating seat structure. The tension frame fixing seat can be locked and fastened to the tension rod. The tension frame fixing seat is set in the mounting groove of the tension frame rotating seat, and the tension frame rotating seat can rotate along the center of the rod hole of the tension frame fixing seat. In particular, the lower part of both sides of the tension frame fixing seat is used to limit the rotation position of the tension frame rotating seat. The spindle tension frame is connected to the tension frame rotating seat. Therefore, in the event of spindle breakage or detachment during the start-up of the spinning machine, it can completely solve the problem of the spindle tension frame falling off or colliding with the roller. The tension frame rotating seat of this invention is connected to the spindle tension frame through fasteners. Therefore, the tension frame fixing seat can be installed on the tension rod first, and the assembled spindle tension frame can be directly set on the tension frame fixing seat through the mounting groove of the tension frame rotating seat. Assembly is more convenient, and installation on the machine is quicker and easier, greatly reducing labor intensity and automatically adjusting the spindle tension.

[0009] This invention features multiple arc-shaped or V-shaped limiting grooves at the counterweight section of the spindle tension frame for adjusting the spindle tension. The counterweight has an opening and a hanging rod at the top. Therefore, the hanging rod is installed in the corresponding arc-shaped or V-shaped limiting groove, making the installation of the counterweight simpler. It does not require screws and can be directly hung on the spindle tension frame. If the position of the counterweight needs to be adjusted during the debugging process, the installation position of the counterweight can be changed directly. The operation is quick and can effectively avoid interference with the lifting box and the middle wall plate. Attached Figure Description

Detailed Implementation

[0024] See Figures 1-4 As shown in Figures 8 and 9, this utility model discloses a novel spindle tension device for textile machines, comprising a spindle tension frame 3, a tension disc 1, a counterweight 6, a tension frame fixing seat 8, and a tension frame rotating seat 5. The spindle tension frame 3 has an upper connecting part 3-1, an outer counterweight part 3-2, and a lower connecting part 3-3. The lower connecting part 3-3 has a limiting groove 3-31 that positions and engages with the tension frame rotating seat 5. The tension disc 1 is mounted on the upper connecting part 3-1 of the spindle tension frame 3 via a first fastener 10. (See Figure 8 for details.) Figures 2-4 As shown, the counterweight 6 of this invention is installed in the counterweight part 3-2 of the belt tension frame 3 and is adjustable. Therefore, the belt tension is adjusted by the position of the counterweight 6. See Figures 2-5 As shown, the tension frame fixing seat 8 of this utility model is used to connect the tension rod 7 and the tension frame rotary seat 5. The tension frame fixing seat 8 has a rod hole 8-3 for fitting onto the tension rod 7 and a mounting hole 8-5 for installing a locking component. The tension frame fixing seat 8 is fitted onto the tension rod 7, and the locking component is installed in the mounting hole 8-5. The tension frame fixing seat 8 is fixed onto the tension rod 7 by the locking component. Multiple tension frame fixing seats 8 can be fixed onto the tension rod 7 offline. See Figures 2-4As shown, the tension frame rotary seat 5 of this utility model has a mounting groove 5-2 that accommodates the recess of the tension frame fixing seat 8 and a mounting seat 5-1 located on one side of the spindle tension frame 3 and connected to the tension frame rotary seat 5. The limiting groove 3-31 on the spindle tension frame 3 is set on the mounting seat 5-1 of the tension frame rotary seat 5 and connected by the second fastener 4. Since the tension frame fixing seat 8 is set in the mounting groove 5-2 of the tension frame rotary seat 5, the spindle tension frame 3 can be connected to the tension frame rotary seat 5, and then its mounting groove 5-2 can be set in the tension frame rotary seat 5. On-site installation is quicker and more convenient on the tension frame fixing seat 8, and it can automatically adjust the spindle tension. The tension frame rotary seat 5 can rotate along the center of the rod hole of the tension frame fixing seat 8. The lower part of the two sides 8-2 of the tension frame fixing seat 8 is used to limit the rotation position of the tension frame rotary seat 5. Therefore, during the tension adjustment process of the spindle, the tension frame tension frame 3 is limited by the tension frame fixing seat 8. During the start-up of the spinning machine, if the spindle breaks or falls off, the spindle tension device will not fall or collide with the roller 9. The tension frame rotary seat 5 and the tension frame fixing seat 8 of this utility model are made of thermoplastic materials, such as polyamide (PA66), polyoxymethylene (POM), polyphenylene sulfide (PPS), and acrylonitrile-butadiene-styrene copolymer (ABS). Therefore, they can all be mass-produced by mold making and are low in cost.

[0025] See Figures 2-4 As shown in Figures 7-9, the spindle tension frame 3 of this utility model has multiple arc-shaped limiting grooves 3-21 or V-shaped limiting grooves at the counterweight part 3-2 for adjusting the tension of the spindle belt. Under the action of the counterweight 6 of the same weight, the tension of the spindle belt is adjusted by the position of the arc-shaped limiting grooves 3-21 or V-shaped limiting grooves. The counterweight 6 has an opening 6-1 and a hanging rod 6-2 at the top. The hanging rod 6-2 is hung in the corresponding arc-shaped limiting groove 3-21 or V-shaped limiting groove. The counterweight 6 of this utility model can be a rectangular block, a pear-shaped block or other shapes. The rectangular block or pear-shaped block is provided with a hanging rod 6-2. Therefore, if the position of the counterweight needs to be adjusted during the debugging process, the installation position of the counterweight can be changed directly. The operation is quick and can also effectively avoid interference with the lifting box and the middle wall plate.

[0026] See Figures 2-4 As shown, when the tension frame rotary seat 5 of this utility model rotates counterclockwise and clockwise to its maximum position along the center of the rod hole of the tension frame fixed seat 8, the angle α between the central plane of the tension frame rotary seat 5 and the central plane of the tension frame fixed seat 8 is between 11.5° ± 1.5°. If this angle α is 11.5°, see... Figure 11 As shown, the tension frame rotary seat 5 rotates along the tension frame fixed seat 8 towards the roller 9 and reaches its limit position. It can also be seen that... Figure 12As shown, the tension frame rotary seat 5 rotates along the tension frame fixed seat 8 towards the lifting box body and reaches its limit position. At this time, the angle α between the center plane of the tension frame rotary seat 5 and the center plane of the tension frame fixed seat 8 is 11.5°±1.5°. Figure 10 As shown, in normal operation, when the included angle α is 0, the center plane of the tension frame rotary seat 5 coincides with the center plane of the tension frame fixed seat 8. Therefore, the rotation angle of the tension frame rotary seat 5 is controlled, thereby limiting the rotation angle of the strip tension frame 3. While tensioning the strip, the problem of the strip tension frame 3 colliding with the roller 9 or falling off when the strip breaks or falls off is solved.

[0027] See Figures 2-5 As shown, the tension frame fixing seat 8 of this utility model has an upper semi-circular rotating surface 8-1 and two side surfaces 8-2 that taper downwards and inwards. The mounting groove 5-2 of the tension frame rotary seat 5 includes a semi-circular groove bottom surface that matches the rotating surface 8-1 at the top and a straight groove bottom surface that is tangent to and parallel to the bottom of the semi-circular groove. The straight groove bottom surface of the mounting groove 5-2 of the tension frame rotary seat 5 is connected to the inclined side surface on the tension frame fixing seat 8 at the bottom for limiting. The groove depth of the mounting groove 5-2 of this utility model is between 10 and 11 mm. For example, if the groove depth of the mounting groove 5-2 is 10.5 mm, the tension frame fixing seat 8 can reliably rotate and be limited when set in the mounting groove 5-2 of the tension frame rotary seat 5.

[0028] This utility model relates to another structure of the tension frame fixing seat 8 and the tension frame rotating seat 5. The tension frame fixing seat 8 has an upper semi-circular arc rotating surface 8-1 and two tangent and parallel side surfaces 8-2. The mounting groove 5-2 of the tension frame rotating seat 5 includes a semi-circular arc groove bottom surface that matches the rotating surface 8-1 at the top and two inclined groove bottom surfaces that connect with the semi-circular arc groove bottom surface and slope downwards and outwards. The inclined groove bottom surface of the mounting groove 5-2 of the tension frame rotating seat 5 connects with the side surface 8-2 of the tension frame fixing seat 8 at the bottom and limits its movement. The tension frame fixing seat 8 limits the movement of the tension frame rotating seat 5. Similarly, the groove depth of the mounting groove 5-2 is 10~11 mm. The tension frame fixing seat 8 is set in the mounting groove 5-2 of the tension frame rotating seat 5 and can reliably rotate and limit its movement.

[0029] See Figure 3 As shown, the tension frame fixing seat 8 of this utility model has a mounting hole 8-5 on the base 8-4. The mounting hole 8-5 has an internal thread hole. The locking member is screwed into the internal thread hole and abuts against the tension rod 7. The upper part of the mounting hole 8-5 has a small internal thread hole and the lower part has a large hole for placing the head of the locking member. The locking member can be a round head screw. When the round head screw is screwed into the tension frame fixing seat 8 on the base 8-4, the head of the round head screw is set in the large hole.

[0030] See Figure 3 , 5As shown, the tension frame rotary seat 5 of this utility model has mounting seats 5-1 at both ends, and the mounting seat 5-1 on the connecting side is provided with a limiting protrusion 5-11. The limiting groove 3-31 on the spindle tension frame 3 is provided with a limiting groove 3-32. The limiting groove 3-31 on the spindle tension frame 3 is set on the mounting seat 5-1 of the tension frame rotary seat 5, and the limiting protrusion 5-11 is set in the corresponding limiting groove 3-32. By the cooperation of the limiting protrusion 5-11 and the limiting groove 3-32, the spindle tension frame 3 is quickly positioned on the tension frame rotary seat 5. The second fastener 4 includes a bolt 4-1 and a nut 4-2. The bolt 4-1 passes through the first hole 3-33 on the spindle tension frame 3 and the second hole 5-3 on the tension frame rotary seat 5 and is locked with the nut 4-2, which facilitates the positioning of the spindle tension frame 3 and its connection with the tension frame rotary seat 5. Figure 3 As shown, in order to facilitate the installation of bolt 4-1 and nut 4-2, the tension frame rotary seat 5 is provided with a limiting surface 5-4 at the second hole 5-3, which is connected to the side of nut 4-2 and prevents rotation. The limiting surface 5-4 is used to hold nut 4-2, which facilitates the installation of bolt 4-1.

[0031] See Figure 2 , 3 As shown, the outer periphery of the tension disc 1 of this utility model has a convex wear-resistant layer 1-1 at the interface between it and the spindle belt. The wear-resistant layer 1-1 is connected to the two sides of the tension disc 1 through an inclined surface, which improves the wear resistance of the tension disc 1 and extends its service life.

[0032] See Figure 4 As shown, the upper connecting part 3-1 of the tension frame 3 of this utility model is an outwardly inclined surface, and the angle β between the inclined surface and the vertical surface is between 173.5-174°. For example, if the angle β between the inclined surface and the vertical surface is 173.8°, the long arm 2-1 of the U-shaped tension disc guard 2 is set on the outside of the tension frame 3. The tension disc guard 2 has a long arm 2-1 and a short arm structure. The first fastener 10 passes through the outer hole on the long arm 2-1 of the tension disc guard 2 and the positioning hole on the tension frame 3 and is screwed onto the inner bushing of the tension disc 1. The first fastener 10 is provided with an oil injection head and an inner oil passage. The tension disc 1 can rotate freely. To prevent the first fastener 10 from loosening, the first fastener 10 passes through the anti-loosening gasket 11 and the outer hole of the tension disc guard 2 and the positioning hole on the tension frame 3 and is screwed onto the inner bushing of the tension disc 1. The tension disc guard 2 limits the swing position of the tension disc. See Figure 4 As shown, the spindle tension frame 3 and the tension disc guard 2 of this utility model are separate structures, and the spindle tension device installed on the spinning machine can be S-twist.

[0033] See Figures 6-9As shown, the spindle tension frame 3 of this utility model has an outwardly extending L-shaped flange at the upper connecting part 3-1, forming a U-shaped mounting seat 3-11. Therefore, by making the spindle tension frame 3 and the tension disc guard into an integrated structure, the angle requirements of the spindle tension frame 3 can be well controlled. See Figure 6 , 7 As shown, the U-shaped mounting base 3-11 of this utility model has an outwardly inclined surface on one side of the spindle tension frame 3. The angle β between the inclined surface and the vertical plane is between 173.5-174°. The outer side 3-12 of the U-shaped mounting base 3-11 tapers inward downwards, and the angle δ between the outer side 3-12 and the vertical plane is between 6.5°-7°. If the angle δ is 6.8°, the center line of the positioning hole on the inclined surface coincides with the center line of the positioning hole on the outer side 3-12. The first fastener 10 passes through the positioning hole on the spindle tension frame 3 and is screwed onto the inner bushing of the tension disc 1. The first fastener 10 is provided with an oil injection head and an inner oil passage. Therefore, the tension disc 1 is mounted on the spindle tension frame 3 at the inclined surface or the outer side 3-12 via the first fastener 10. See Figure 8 As shown, the first fastener 10 passes through the positioning hole on the inclined surface of the spindle tension frame 3 and connects to the tension disc 1. At this time, the spindle tension device installed on the spinning frame is in a Z-twist configuration. See Figure 9 As shown, the first fastener 10 passes through the positioning hole on the outer side 3-12 of the spindle tension frame 3 and is connected to the tension plate 1. At this time, the spindle tension device installed on the spinning machine is in S twist. This utility model installs the tension plate 1 through two different mounting surfaces on the integrated tension frame. Therefore, different mounting positions of the tension plate 1 can achieve Z twist and S twist.
