Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, and in particular to a tensioning device for pearl cotton winding machines. Background Technology

[0002] In the process of winding EPE cotton using an EPE cotton winding machine, in order to ensure that the EPE cotton is wound flat, avoid wrinkles and loosening, control the tightness of the roll, and ensure the molding quality, a tensioning device is usually used to tension the wound EPE cotton. Existing tensioning devices usually consist of a tensioning frame and a tensioning roller.

[0003] For example, utility model application CN201920859084.2 discloses a winding machine for processing pearl cotton, including a base, a first support column on the base, a first bearing in the first support column, a first roller shaft in the middle of the first bearing, pearl cotton on top of the first roller shaft, a second support column on one side of the first support column, a second bearing in the middle of the second support column, a second roller shaft in the middle of the second bearing, a third support column on the other side of the second support column, a third bearing in the middle of the third support column, a third roller shaft in the middle of the third bearing, a crossbeam at the upper end of the third support column, a resistance plate between the third support columns, a motor base on the other side of the third support column, a power distribution cabinet behind the motor base, and a motor mounted on the motor base. This utility model effectively solves the problem of static electricity generation in traditional winding machines for pearl cotton processing.

[0004] However, with current traditional tensioning devices, during prolonged contact between the tensioning roller and the pearl cotton, friction between the two can easily lead to wear, grooving, and reduced smoothness on the surface of the tensioning roller. In such cases, the tensioning roller needs to be replaced. However, since tensioning rollers are mostly integrally molded, once the surface of the tensioning roller is worn, even if the core components such as the roller shaft and bearings are intact, the entire tensioning roller needs to be replaced, resulting in the waste of undamaged parts and making it inconvenient to use. Utility Model Content

[0005] In view of this, the present invention provides a tensioning device for a pearl cotton winding machine, which has an auxiliary compensation block that allows for easy replacement of only the worn part of the tensioning roller. After the auxiliary compensation block becomes worn, simply press the fixed slide to make the fixed slide slide in the connecting seat and squeeze the connecting spring. As the fixed slide slides, it will disengage from the fixed slot. At this time, the worn auxiliary compensation block can be removed and replaced without replacing the entire tensioning roller.

[0006] This utility model provides a tensioning device for a pearl cotton winding machine, specifically including: a fixed base plate; a tensioning frame fixedly connected to the front of the top surface of the fixed base plate; a winding roller fixedly connected to the rear of the top surface of the fixed base plate; the winding roller and the tensioning frame are aligned; two first mounting brackets are symmetrically slidably connected inside the tensioning frame; a second mounting bracket is inserted into the front of each of the two first mounting brackets; the two second mounting brackets are slidably connected inside the tensioning frame; a tensioning roller is provided between the two first mounting brackets and the two second mounting brackets; and multiple sets of auxiliary compensation blocks are inserted into the outside of the tensioning roller in a circular array.

[0007] Optionally, a lifting slider is fixedly connected to the rear end face of each of the two first mounting brackets; the two lifting sliders are slidably connected inside the tensioning frame; two adjusting screws are symmetrically rotatably connected inside the tensioning frame; the two lifting sliders are respectively threaded to the outside of the two adjusting screws.

[0008] Optionally, a drive pulley is coaxially fixedly connected to the upper part of each of the two adjusting screws; both drive pulleys are arranged inside the tensioning frame; and the two drive pulleys are connected by a drive belt.

[0009] Optionally, each of the two first mounting brackets is fixedly connected to a set of fixing brackets; each of the two sets of fixing brackets is slidably connected to a set of locking brackets; each of the two sets of locking brackets is fixedly connected to a set of fixing springs; the ends of the two sets of fixing springs are respectively fixedly connected to the two sets of fixing brackets; each of the two second mounting brackets is fixedly connected to a set of fixing seats; the two sets of fixing seats are respectively inserted into the two sets of fixing brackets; each of the two sets of fixing seats has a locking slot on its exterior; the two sets of locking brackets are respectively inserted into the two sets of locking slots.

[0010] Optionally, the tension roller has multiple sets of connecting seats symmetrically fixedly connected in a ring array on its exterior; each of the multiple sets of connecting seats has a set of fixed slides symmetrically slidably connected inside; each of the multiple sets of fixed slides has a set of connecting springs fixedly connected to its inner side; the ends of the multiple sets of connecting springs are respectively fixedly connected to the multiple sets of connecting seats; each of the multiple sets of auxiliary compensation blocks has a fixed slot symmetrically opened on its exterior; and the multiple sets of fixed slides are respectively inserted into the multiple sets of fixed slots.

[0012] Beneficial effects

[0013] During use, this utility model utilizes an auxiliary compensation block to compensate for the wear of the tension roller. When the auxiliary compensation block wears out, simply press the fixed slide to disengage it from the fixed slot, then remove and replace the worn auxiliary compensation block. This eliminates the need to replace the entire tension roller, significantly reducing material waste and maintenance costs, and avoiding the waste associated with replacing the entire roller. Furthermore, it allows for quick replacement of arc plates made of different materials based on the characteristics of pearl cotton, without needing to replace the entire tension roller. This flexibly adapts to production needs, reduces product defect rates, and provides simple and quick operation, effectively improving the practicality of the pearl cotton winding machine's tensioning device and making it more convenient to use.

[0014] By pulling the locking bracket to disengage it from the locking slot, the second mounting bracket can be removed from the first mounting bracket to replace the tension roller. This allows for quick replacement of the tension roller by the operator and effectively improves the convenience of the tensioning device of the pearl cotton winding machine.

[0032] This utility model proposes a tensioning device for a pearl cotton winding machine. Please refer to [reference needed]. Figures 1 to 11 Includes: a fixed base plate 1;

[0033] A tensioning frame 101 is fixedly connected to the front of the top surface of the fixed base plate 1; a take-up roller 113 is fixedly connected to the rear of the top surface of the fixed base plate 1; the take-up roller 113 is aligned with the tensioning frame 101; two first mounting brackets 105 are symmetrically slidably connected inside the tensioning frame 101; a second mounting bracket 106 is inserted into the front of each of the two first mounting brackets 105; the two second mounting brackets 106 are slidably connected inside the tensioning frame 101; a tensioning roller 112 is provided between the two first mounting brackets 105 and the two second mounting brackets 106; multiple sets of auxiliary compensation blocks 114 are inserted into the outer side of the tensioning roller 112 in a ring array.

[0034] Each of the two first mounting brackets 105 has a lifting slider 103 fixedly connected to its rear end face; both lifting sliders 103 are slidably connected inside the tensioning frame 101; two adjusting screws 102 are symmetrically rotatably connected inside the tensioning frame 101; and the two lifting sliders 103 are threadedly connected to the outside of the two adjusting screws 102 respectively.

[0035] Each of the two adjusting screws 102 has a drive pulley 104 coaxially fixedly connected to its upper part; both drive pulleys 104 are set inside the tensioning frame 101; the two drive pulleys 104 are connected by a drive belt.

[0036] Each of the two first mounting brackets 105 is fixedly connected to a set of fixing brackets 107; each of the two sets of fixing brackets 107 is slidably connected to a set of locking inserts 108; each of the two sets of locking inserts 108 is fixedly connected to a set of fixing springs 109; the ends of the two sets of fixing springs 109 are respectively fixedly connected to the two sets of fixing brackets 107; each of the two second mounting brackets 106 is fixedly connected to a set of fixing seats 110; the two sets of fixing seats 110 are respectively inserted into the two sets of fixing brackets 107; each of the two sets of fixing seats 110 has a locking slot 111 on its exterior; the two sets of locking inserts 108 are respectively inserted into the two sets of locking slots 111.

[0037] The tension roller 112 has multiple sets of connecting seats 116 symmetrically fixedly connected in a ring array on its exterior; each set of connecting seats 116 has a set of fixed slides 117 symmetrically slidably connected inside; each set of fixed slides 117 has a set of connecting springs 118 fixedly connected to its inner side; the ends of the connecting springs 118 are respectively fixedly connected to the multiple sets of connecting seats 116; each set of auxiliary compensation blocks 114 has a fixed slot 115 symmetrically opened on its exterior; the multiple sets of fixed slides 117 are respectively inserted into the multiple sets of fixed slots 115.

[0038] The specific usage and function of this embodiment are as follows: The pearl cotton is wound up by the take-up roller 113 and tensioned by the tension roller 112. Rotating the adjusting screw 102 causes the lifting slider 103 to rise and fall. The rising and falling of the lifting slider 103 causes the first mounting bracket 105 to rise and fall, which in turn causes the second mounting bracket 106 to rise and fall. The rising and falling of the first and second mounting brackets 105, in turn, causes the tension roller 112 to rise and fall, thus adjusting the tension of the pearl cotton. During the rotation of the adjusting screw 102 on one side, the corresponding drive pulley 104 rotates. The rotation of the drive pulley 104 on one side causes the drive pulley 104 on the other side to rotate via the drive belt. This rotation of the drive pulley 104 on the other side then causes the corresponding adjusting screw 104 to rotate. Rotating screw 102 causes the two adjusting screws 102 to rotate synchronously, stabilizing the tension roller 112. By pulling the locking bracket 108, the locking bracket 108 slides on the fixed bracket 107 and presses the fixed spring 109. As the locking bracket 108 slides, it disengages from the locking slot 111. Only then can the second mounting bracket 106 be removed from the first mounting bracket 105, and the tension roller 112 be replaced. The auxiliary compensation block 114 can compensate for the wear of the tension roller 112. After the auxiliary compensation block 114 wears out, simply press the fixed slide 117 to make it slide in the connecting seat 116 and press the connecting spring 118. As the fixed slide 117 slides, it disengages from the fixed slot 115. Only then can the worn auxiliary compensation block 114 be removed and replaced. It is not necessary to replace the entire tension roller 112.

[0039] Example 2:

[0040] Based on Example 1, please refer to Figures 1 to 11 It includes: auxiliary seats 119, limit stops 120 and auxiliary torsion springs 121. Limit stops 120 are provided on the outer side of multiple sets of connecting seats 116. Multiple sets of auxiliary seats 119 are fixedly connected to the outside of the tension roller 112 in a symmetrical annular array. Multiple sets of limit stops 120 are respectively hinged to the multiple sets of auxiliary seats 119. Auxiliary torsion springs 121 are fixedly connected to the outside of the rotating shaft of multiple sets of limit stops 120. The ends of multiple sets of auxiliary torsion springs 121 are respectively fixedly connected to the multiple sets of auxiliary seats 119.

[0041] The specific usage and function of this embodiment are as follows: Under the action of the elastic potential energy of the auxiliary torsion spring 121, the limiting stop 120 will be locked inside the fixed slide 117, limiting the fixed slide 117 and preventing the fixed slide 117 from sliding accidentally. When it is necessary to replace the auxiliary compensation block 114, simply rotate the limiting stop 120 to flip it over to release the limitation of the fixed slide 117.
