A yarn guide device for glass fiber yarn

Abstract

This utility model discloses a fiberglass yarn guiding device, relating to the field of fiberglass winding and guiding technology. It includes a base, with an mounting platform installed at the top center of the base. Two fixed frames are fixed to the top of the mounting platform, and movable plates are mounted on the inner walls of each fixed frame via bearings. Two movable plates are positioned above the mounting platform, and a rotating rod is mounted on one side of each movable plate via a rotating shaft. Two fixing strips are fixed to the outer walls of each rotating rod. This utility model uses a rotating disk to drive the fixed column at its top to rotate. The force applied by the fixed column to the inner wall of the through groove causes the movable frame to reciprocate, thus enabling the yarn guide to reciprocate. By changing the position of the threaded block, the distance between the fixed column and the center of the rotating disk can be adjusted, thereby changing the reciprocating distance of the yarn guide to adapt to spools of different lengths.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example: See Figure 1-5 A yarn guide device for glass fiber yarn comprises a base 12, a mounting platform 16 is installed at the middle position of the top of the base 12, and two fixing frames 17 are fixed on the top of the mounting platform 16, and the inner wall of the fixing frame 17 is installed with a moving plate 7 through a bearing, two moving plates 7 are arranged above the mounting platform 16, and a rotating rod 13 is installed on one side of the moving plate 7 through a rotating shaft, two fixing bars 30 are fixed on the outer wall of the rotating rod 13, and the rotating rod 13 and the fixing bar 30 are both penetrated to one end of a rotating cylinder 2, a clamping plate 14 is fixed to one end of the rotating rod 13, an adjusting component for adjusting the position of the moving plate 7 is arranged below the moving plate 7, a driving component for driving the rotating cylinder 2 to rotate is arranged at one end of the rotating cylinder 2, support plates 8 are fixed on both sides of the top of the base 12, and a top plate 1 is installed on the top of the two support plates 8, and the top A moving frame 5 is arranged above the plate 1, and a through slot 21 is vertically penetrated at the top of the moving frame 5, a connecting rod 26 is fixed at one end of the bottom end of the moving frame 5, and the bottom end of the connecting rod 26 extends to the bottom of the top plate 1 and is fixed with a yarn guide 27, a third servo motor 19 is installed at the middle position of the bottom end of the top plate 1, and the output end of the third servo motor 19 extends to the top of the top plate 1 and is installed with a rotating disk 4, a sliding groove 25 is opened on one side of the top end of the rotating disk 4, and a threaded rod 23 is installed at one end of the sliding groove 25 through a rotating shaft, one end of the threaded rod 23 extends to the outside of the rotating disk 4, and a threaded block 24 is sleeved on the outer wall of the threaded rod 23 in the sliding groove 25, a sliding connection is formed between the threaded block 24 and the sliding groove 25, and a fixed column 20 is fixed at the top end of the threaded block 24, and the top end of the fixed column 20 extends to the inside of the through slot 21;

[0025] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, when installing the bobbin, the bobbin is placed between the two clamping plates 14, and then the two moving plates 7 are moved toward each other by the same distance by means of the adjustment assembly. The movement of the moving plate 7 drives the clamping plate 14 through the rotating rod 13, so that the clamping plate 14 presses the bobbin tightly. An arc-shaped protrusion is also provided on one side of the clamping plate 14 to assist in positioning the bobbin and keep the rotation center of the bobbin and the clamping plate 14 aligned. After the bobbin position is determined, the threaded rod 23 is rotated to cause the threaded block 24 to move in a directional manner, thereby changing the distance between the fixed column 20 and the center of the rotating disk 4 as needed. Subsequently, as the third servo motor 19 drives the rotating disk 4 to rotate, the fixed column 20 can apply force to the inner wall of the through slot 21, causing the moving frame 5 to reciprocate in the horizontal direction, thereby causing the yarn guide 27 used for guiding the glass fiber to reciprocate within the bobbin range.

Guide blocks are installed at both the front and rear ends of the moving frame 5, and the moving frame 5 is slidably connected to the fixed plate 3 through the cooperation between the guide blocks and the guide grooves.

[0027] Specifically, Figure 1 and Figure 2 As shown, the fixed plate 3 guides and limits the movement of the moving frame 5, so that the movement of the moving frame 5 is more stable.

[0028] A fixing ring 22 is arranged outside the threaded rod 23 at one end of the rotating disk 4, and one end of the fixing ring 22 is fixed to the outer wall of the rotating disk 4. A knob is fixed to one end of the threaded rod 23 inside the fixing ring 22, and the diameter of the knob is equal to the inner diameter of the fixing ring 22. An inner hexagonal hole is opened at one end of the knob.

[0029] Specifically, Figure 2 As shown, there is a large friction between the knob and the fixing ring 22, and there is no good fulcrum on the knob, so the knob can be prevented from shifting. In order to facilitate the rotation of the knob to drive the threaded rod 23 to rotate, a tool can be used to cooperate with the inner hexagonal hole to drive the knob to rotate.

[0030] The adjustment component includes a second servo motor 11, which is installed on one side of the mounting platform 16, and a rotating shaft 15 is installed at the output end of the second servo motor 11, one end of the rotating shaft 15 is connected to one end inside the mounting platform 16 through a rotating shaft, and two moving blocks 18 are sleeved on the outer wall of the rotating shaft 15 inside the mounting platform 16, and the moving blocks 18 are all slidably connected to the mounting platform 16, and the top ends of the two moving blocks 18 are respectively fixed to the bottom ends of the two moving plates 7;

[0031] The two ends of the outer wall of the rotating shaft 15 are respectively provided with external threads in opposite directions, and the inner wall of the moving block 18 is respectively provided with internal threads matching therewith;

[0032] Specifically, Figure 1 As shown, starting the second servo motor 11 can mobilize the rotation shaft 15 to rotate, thereby causing the two moving blocks 18 on the outer wall of the rotation shaft 15 to move toward each other, thereby driving the moving plate 7 to move.

[0033] The driving assembly includes a first servo motor 9, which is mounted on one side of one of the support plates 8, and a rotating rod 10 is mounted on the output end of the first servo motor 9, and a sprocket 6 is fixed to one end of the rotating rod 10 and the outer wall of the rotating cylinder 2 near the first servo motor 9, and the outer walls of the two sprockets 6 are sleeved with chains 29;

[0034] Specifically, Figure 1 , Figure 4 and Figure 5 As shown, starting the first servo motor 9 can drive the rotating rod 10 to rotate, thereby causing the sprocket 6 connected to the rotating rod 10 to rotate. The cooperation between the sprocket 6 and the chain 29 can cause the rotating drum 2 equipped with the sprocket 6 to be driven to rotate. The rotation of the rotating drum 2 can drive the rotating rod 13 to rotate due to the cooperation between the groove inside the rotating drum 2 and the fixed bar 30, thereby driving the wire drum to rotate through the clamping plate 14 to perform the winding operation.

[0035] A vertical plate 28 is fixed to the top of the base 12, and the inner wall of the vertical plate 28 is connected to the outer wall of the rotating rod 10 through a bearing;

[0036] Specifically, Figure 4 As shown, the vertical plate 28 can support the rotating rod 10 to improve its stability.
