Description

Technical Field

[0001] The utility model relates to the technical field of spindle rod tension, in particular to a tension device for a creel spindle rod. Background Art

[0002] The spindle of a twisting or doubling machine is used to hold the bobbin, allowing it to rotate freely. Traditionally, the spindle consists of a spindle and a cap. The caps are attached to both ends of the spindle. The caps are axially restrained by retaining springs on the spindle. Three spring-loaded caps, backed by springs, are mounted on the cap's circumference. During operation, the bobbin fits over the caps, and the caps automatically press against the inner surface of the bobbin, securing it in place.

[0003] A Chinese patent (publication number: CN 214779943 U) discloses a textile creel spindle that is easy to adjust tension. The scale movable plate moves back and forth on the scale end surface, squeezing the spring shaft so that the spindle tension can be adjusted. However, since the damping fixed end shaft 401 and the external fixed end 406 in the above document are connected by a buckle connection, the scale movable plate and the scale end are also buckled. When the buckle is operated, the operator usually needs to pull it out with force or use external tools to pry it up, which makes it inconvenient to adjust the tension of the spindle, and the fixed part of the scale movable plate and the scale end is also prone to damage.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 4 In this embodiment, a tension device for a creel spindle rod comprises a spindle rod main body 1, a spindle cap assembly main body 2 is fixed to both ends of the outer surface of the spindle rod main body 1, a fixed end 3 is fixed to the opposite ends of the two spindle cap assembly main bodies 2, the outer surface of the fixed end 3 is slidably connected with a movable end 4, a tension structure is provided at the opposite ends of the left and right fixed ends 3, and a positioning structure is provided on the outer surfaces of the two movable ends 4.

[0023] See also Figure 1 、 Figure 3 and Figure 4 The positioning structure in this embodiment includes connecting blocks 61 fixed to the upper and lower ends of the two movable ends 4, and the interiors of the upper and lower groups of connecting blocks 61 are slidably connected with positioning blocks 62, and the front and rear ends of the positioning blocks 62 are fixed with cross bars 63, and the interiors of the cross bars 63 are slidably connected with limiting rods 64. The positioning structure also includes a pulling structure arranged at the opposite ends of the upper and lower groups of positioning blocks 62.

[0024] Among them, the opposite walls of the upper and lower connecting blocks 61 are each provided with a through hole for the positioning block 62 to pass through the interior thereof, and the upper and lower ends of the two movable ends 4 are each provided with a connecting hole for the positioning block 62 to pass through the interior thereof, so that the positioning block 62 can be moved out of the connecting block 61 through the through hole and the connecting hole, and moved into the inner side of the movable end 4.

[0025] In addition, multiple positioning grooves are provided on the upper and lower ends of the two fixed ends 3, and the positioning blocks 62 are inserted into the interior of the positioning grooves. The positioning blocks 62 move into the positioning grooves so that the movable end 4 can be fixed to the surface of the fixed end 3 through the same group of two positioning blocks 62.

[0026] In addition, the upper and lower ends of the two limiting rods 64 in the same group and the upper and lower walls of the inner cavity of the connecting block 61, as well as the opposite ends of the upper and lower cross bars 63, are provided with through holes for allowing the limiting rods 64 to pass through the interior. The cross bars 63 can slide on the surface of the limiting rods 64 through the through holes, thereby limiting the movement range of the two cross bars 63.

[0027] See also Figures 3 to 4 The pulling structure in this embodiment includes a driving plate 65 that is slidably connected to the inside of the left and right groups of connecting blocks 61. A pull rod 66 is fixed to the opposite wall of the left and right groups of driving plates 65. A pull ring 67 is fixed to the opposite end of the left and right groups of pull rods 66. A resistance spring 68 is adjusted on the outer surface of the pull rod 66.

[0028] Secondly, the driving plate 65 is a rectangle with a hollow interior and missing upper and lower ends, so that when the cross bar 63 drives the positioning block 62 to move into the connecting block 61, the positioning block 62 can move into the inner side of the driving plate 65. The front and rear ends of the driving plate 65 are provided with driving grooves for the cross bar 63 to slide inside it. The driving groove is inclined. The cross bar 63 moves up and down in the driving groove, so that the driving plate 65 can push it to move up and down, so that the cross bar 63 can drive the positioning block 62 to move up and down, and the driving plate 65 is located between the two limiting rods 64 on the same side to prevent it from affecting the left and right movement of the driving plate 65.

[0029] In addition, the opposite walls of the left and right connecting blocks 61 are each provided with a circular hole for the pull rod 66 to pass through, so that the pull rod 66 can be moved out of or into the connecting block 61 so that it can be connected to the pull ring 67.

[0030] See also Figures 1 to 3 The tension structure in this embodiment includes two slots 53 opened at the opposite ends of the left and right fixed ends 3. The interiors of the two groups of slots 53 are slidably connected with T-shaped rods 51, and the outer surface of the T-shaped rods 51 is sleeved with tension springs 52.

[0031] At the same time, the fixed end 3 is a cylindrical shape with a hollow interior and missing left and right ends, the movable end 4 is a cylindrical shape with a hollow interior, and the opposite ends of the two movable ends 4 are missing, and the two movable ends 4 are each provided with a connecting hole at the opposite ends, so that the movable end 4 can move on the surface of the spindle rod body 1 through the connecting hole.

[0032] In addition, the opposite ends of the left and right groups of T-shaped rods 51 are fixed to the opposite walls of the inner cavity of the two movable ends 4, so that the movable ends 4 can drive the T-shaped rods 51 to move in the slots 53 when moving, so that the T-shaped rods 51 can squeeze the tension springs 52.

[0033] The working principle of the above embodiment is:

[0034] When in use, pull the two pull rings 67 to move away from each other, and the pull rings 67 drive the left and right groups of driving plates 65 to move away from each other through the left and right groups of pull rods 66, so that the driving plates 65 squeeze the resistance springs 68, so that when the driving plates 65 move, the cross bar 63 slides in the driving groove of the driving plates 65, so that the cross bar 63 moves from the inclined end of the driving groove to the other end, so that the upper and lower driving plates 65 can pull the upper and lower positioning blocks 62 to move away from each other through the two groups of cross bars 63, so that the positioning blocks 62 can be moved out of the positioning groove of the fixed end 3, and the movable end 4 can be moved on the surface of the fixed end 3, thereby facilitating the adjustment of the tension of the spindle rod body 1.
