Description

Technical Field

[0001] The utility model belongs to the technical field of rubber hose manufacturing, and in particular relates to a device for automatically adjusting the tension of a spindle of a rubber hose winding machine. Background Art

[0002] When producing a hose, it is necessary to wind the steel wire around the outside of the hose base, so a winding machine is needed. During the winding process, the winding machine needs to provide tension to the steel wire through a spindle when working. The spindle includes a shell 1, a fixed ring 4, a rotating shaft 2, a rotating disk 3, a first pulley 11, a second pulley 12, and a torsion spring 6. The shell 1 is a cylindrical structure with an opening at one end. A through hole is provided at the center of the bottom plate of the shell 1. A rotating shaft 2 is inserted inside the through hole. One end of the rotating shaft 2 extending outside the through hole is fixedly connected to the center of the rotating disk 3, and the rotating shaft 2 drives the rotating disk 3 to rotate synchronously. A circular ring 4 is provided on the inner side of the opening of the shell 1. The fixed ring 4 is sleeved on the outer side of the rotating shaft 2. A sliding groove is provided on the inner side of the shell 1. The outer edge of the fixed ring 4 is slidably connected to the inside of the sliding groove, so as to realize the rotation of the fixed ring 4 on the inner side of the opening of the shell 1. An operating hole 5 is provided on the outer cylindrical surface of the fixed ring 4, and the fixed ring 4 is controlled to rotate through the operating hole 5. A torsion spring 6 is provided between the fixing ring 4 and the bottom plate of the housing 1. The torsion spring 6 is sleeved on the outside of the rotating shaft 2. One end of the torsion spring 6 is fixedly connected to the fixing ring 4, and the other end of the torsion spring 6 is fixedly connected to the outer side of the rotating shaft 2. The rotation angle between the rotating shaft 2 and the fixing ring 4 is limited by the torsion spring 6. A locking screw 7 is screwed on the side wall. The tip of the locking screw 7 extends into the inner side of the housing 1 and is in close contact with the outer side of the fixing disk, thereby fixing the fixing ring 4 to the housing 1, and further limiting the stretching degree of the torsion spring 6. The end of the rotating shaft 2 away from the rotating disk 3 passes through the fixing ring 4, and a plug hole 8 is provided at the center of the end of the rotating shaft 2 away from the rotating disk 3. Two symmetrical docking blocks 9 are fixedly provided on both sides of the plug hole 8. A positioning groove 10 is provided at the end of the side wall of the housing 1 away from the rotating disk 3. An L-shaped bracket is fixedly arranged at one side edge of the rotating disk 3, one end of the bracket is fixedly connected to the outer edge of the end surface of the rotating disk 3 away from the housing 1, and the other end of the bracket extends to the outside of the outer cylindrical surface of the housing 1. A first pulley 11 is rotatably arranged on the bracket, and the rotation axis of the first pulley 11 is arranged along the radial direction of the housing 1. A protruding block is arranged on the outer cylindrical surface of the housing 1, and the protruding block is located on the side facing the rotating disk 3. A second pulley 12 is rotatably arranged on the protruding block, and the rotation axis of the second pulley 12 is arranged along the radial direction of the housing 1. The second pulley 12 is located on one side of the first pulley 11.

[0003] Since different types of hoses require different tensions from the spindle when winding, the tension inside the spindle needs to be adjustable. At this time, it is necessary to loosen the locking screw 7 on the housing 1, and adjust the stretching degree of the torsion spring 6 by rotating the fixing ring 4, thereby adjusting the elastic force of the torsion spring 6, and then adjusting the tension provided by the spindle. The existing adjustment method is to adjust manually, which has low adjustment efficiency and poor adjustment quality. Utility Model Content

[0048] The working principle of the utility model is:

[0049] Step 1: When the tension of the spindle needs to be adjusted, the rotating shaft 2 of the spindle is sleeved on the end of the plug-in shaft 17 away from the fixed plate 16, so that the two docking blocks 9 on the rotating shaft 2 of the spindle are plugged into the two docking grooves 19 on the reel 18, and the positioning block 23 on the fixed seat 20 is plugged into the positioning groove 10 on the outer shell 1 of the spindle, so that the rotating shaft 2 of the spindle can rotate synchronously with the reel 18, and the outer shell 1 of the spindle is fixed to the fixed seat 20 and cannot rotate. At the same time, the electromagnetic suction 40 is in the power-on state, the electromagnetic suction 40 is in contact with the iron block 39, the plug-in rod 34 extends into the telescopic cylinder, and the outer end of the plug-in rod 34 is out of contact with the fixed ring 4 of the spindle.

[0050] Step 2: One end of the wire rope 41 is fixedly wound on the drum 18, and the other end of the wire rope 41 is passed around the transition rod 21, the third pulley 22, the second pulley 12, and the first pulley 11 in sequence, and then the hook 47 on the wire rope 41 is hooked to the detection ring on the tension sensor 46.

[0051] Step 3: Set the required tension value.

[0052] Step 4: Control the electromagnetic suction 40 to cut off the power, the electromagnetic suction 40 has no magnetic attraction, and under the action of the rebound force of the reset spring 38, the plug-in rod 34 extends to the outside, and the iron block 39 is out of contact with the electromagnetic suction 40. At this time, the outer end of the plug-in rod 34 is in contact with the outer cylindrical surface of the fixing ring 4 of the spindle. At this time, the iron block 39 is still on the light between the opposing infrared photoelectric switches 42.

[0053] Step 5: Control the moving motor 29 to start rotating, the moving motor 29 drives the driving gear 30 to rotate, and the driving gear 30 drives the driven gear 31 to rotate. Since the driven gear 31 is meshed with the arc rack 32, and the arc rack 32 is fixed on the fixed track 24, the moving seat 25 is driven to slide on the arc track, thereby driving the outer end of the plug rod 34 to slide on the outer cylindrical surface of the fixed ring 4. When the moving seat 25 slides to one end of the fixed track 24, the sliding block on the moving seat 25 contacts one end of the arc groove of the fixed track 24, and the moving seat 25 stops sliding. At this time, the moving motor 29 starts to rotate in the opposite direction, and the moving seat 25 starts to slide in the opposite direction on the fixed track 24. Until the outer end of the plug rod 34 is inserted into the operating hole 5 on the fixed ring 4, the reset spring 38 is further stretched, and the iron block 39 is not on the light between the opposite-beam infrared photoelectric switch 42. At this time, the opposite-beam infrared photoelectric switch 42 transmits a signal to the controller to control the moving motor 29 to stop rotating.

[0054] Step 6: Loosen the locking screw 7 on the spindle housing 1 so that the fixing ring 4 can rotate relative to the housing 1.

[0055] Step 7: Control the piston rod of the electric push rod 44 to extend, drive the tension sensor 46 to move forward, and the tension sensor 46 straightens the wire rope 41 until the tension sensor 46 detects a stable tension value, and the electric push rod 44 stops moving.

[0056] Step 8: Compare the tension value detected by the tension sensor 46 with the set tension value. If the tension value detected by the tension sensor 46 is greater than the set tension value, the moving motor 29 is controlled to rotate in the forward direction, and the moving seat 25 slides in the forward direction on the fixed track 24. The plug-in rod 34 drives the fixed rod to rotate in the forward direction along with the moving seat 25, so that the fixed ring 4 and the rotating shaft 2 rotate relative to each other, thereby adjusting the elastic force of the torsion spring 6, until the tension value detected by the tension sensor 46 is equal to the set tension value, the moving motor 29 stops rotating, and the locking screw is tightened. 7. Fix the fixing ring 4 to the housing 1; if the pulling force value detected by the pulling force sensor 46 is less than the set tension value, control the moving motor 29 to rotate in the opposite direction, and the moving seat 25 slides in the opposite direction on the fixed track 24. The plug-in rod 34 drives the fixing rod to rotate in the opposite direction along with the moving seat 25, thereby rotating the fixing ring 4 relative to the rotating shaft 2, thereby adjusting the elastic force of the torsion spring 6, until the pulling force value detected by the pulling force sensor 46 is equal to the set tension value, the moving motor 29 stops rotating, and tightens the locking screw 7 to fix the fixing ring 4 to the housing 1.

[0057] Step 9: Control the electromagnetic suction 40 to be energized, the electromagnetic suction 40 has magnetic attraction, the iron block 39 and the electromagnetic suction 40 are re-contacted, and the outer end of the plug rod 34 is pulled out from the operating hole 5 of the fixing ring 4.
