Description
Technical field
The utility model relates to the structure of turning cylinder, particularly a kind of damping structure that is used to lead paper roller.
Background technology
The original-pack paper roller damper of leading of existing Lilezhen, as shown in Figure 1, this damping arrangement comprises: mounting bracket 280, plunging joint 290, damper 320, jackscrew 585, bolt 590, hold-down bolt 595, hexagonal bar iron 720 and parallel pin 970, this damper is by the revolution ratio between the gear, improve or reduce rotary resistance, very easily damage, and to regulate the friction drag that comes out be the value of fixing, be difficult to reach the tensioning of paper road or the actual production requirement such as loosen so resistance is regulated.And resistance is not easy to be adjusted in the OK range, tightly pulls open the packing paper tube easily if can cause paper to be passed by, thereby destroys gnotobasis; Can cause packaging material sideslip in operational process if paper is passed by pine, the paper road swings during the packaging material splicing, and directly the size of the vertical envelope of influence degree of overlapping causes normally involution of packaging material, even causes paper tube to break in the operational process.Simultaneously, this damper price is at 13663.63 yuan, and buying expenses is higher.
At present, many users adopt the mode of holding paper, increase to lead the rotary resistance of paper roller, limit the rotating speed of leading paper roller, this way belongs to stopgap, cures the symptoms, not the disease, and can produce the ash bits, if the ash bits can bring hidden danger of quality to product attached to the packaging material inside face.
The utility model content
The purpose of this utility model is, provides a kind of brand new to be used to lead the damping structure of paper roller.
For achieving the above object, a kind of damping structure that is used to lead paper roller of the present utility model is characterized in that described damping structure comprises: fixed support 1, this fixed support 1 are installed on the adapter plate of leading the paper roller both sides; Be fixed with columniform adjusting cavity 5 on the described fixed support 1, be coaxially arranged with in this adjusting cavity 5: back pressure adjustable bolt 2, back pressure guide shaft 3, back pressure spring 6 and resistance rod 4;
Described adjusting cavity 5 has negative thread away from an end of the turning cylinder of leading paper roller, is used to regulate the degree of depth that cavity 5 is regulated in 2 precessions of back pressure adjustable bolt; The inner of described back pressure adjustable bolt 2 is resisted against the end that back pressure guide shaft 3 has boss, and the cylinder of these back pressure guide shaft 3 other ends partly is sheathed in the back pressure spring 6; Described back pressure spring 6 is arranged in the endoporus of resistance rod 4, and the outer end of this resistance rod 4 is a boss, the friction face 7 of its outer end circular arc and the turning cylinder engagement of leading paper roller.
Damping structure of the present utility model is by cw or left-hand revolution pressure adjustment knob 1, the back pressure guide shaft of regulating in the cavity 53 is increased or reduces pressure, this transmission of pressure to and back pressure guide shaft 3 and resistance rod 4 between on the back pressure spring 6 that is provided with of compression, thereby apply or reduce the back pressure that resistance rod 4 is produced, variation along with resistance rod 4 back pressures, promptly realized increase or reduction squeezed state to resistance rod 4, friction face 7 will produce different friction drags like this, and the variation by friction drag reaches the control to the rotation situation of leading paper roller.
As a kind of improvement of technique scheme, described friction face 7 is non-smooth surface; Also be provided with the pressure adhesive tape that the rubber material is made on the described friction face 7.
Because long-time the use, contact surface can reduce friction drag because of friction, the scheme that solves is to destroy its contact surface degree of finish in the resistance rod front, secondly can use two-in-one glue in the bonding one hundred sharp pressure adhesive tape of using the rubber material of the arc-shaped surface of resistance rod, antagonistic force in bonding back owing to resistance, this adhesive tape can be stable the surface that bonds to damper bar, can not produce simultaneously any bad accessory substance.
Another kind as technique scheme improves, and described resistance rod 4 adopts polytetrafluoroethylene to make.Because the motion rotating speed changes 1100/hour, therefore, the speed of rotation is lower, the heat that contact surface produced is less, and the material of polytetrafluoroethylene is more heat-resisting, wear-resisting, can be because of pivoting friction does not produce bad air or other accessory substance, use not only environmental protection but also durable.
Advantage of the present utility model is, compares with existing damper, damping structure of the present utility model is by the raising of the friction force of direct contact surface or reduction, limits the running state of rotor wheel.
Install damping structure of the present utility model on the paper roller additional original-pack the leading of Lilezhen, adjusting by the backpressure regulation bolt, increase or reduce the friction drag of contact surface by the spring that transmits pressure, spring plays the effect of buffering when resistance is regulated simultaneously, resistance can be along with rotating free adjustment like this, avoided because of fixed resistance influences paper road operation, also avoided not having the influence of resistance buffering tensioning of paper road or the effective adaptation when lax; Simultaneously, this dumping force goes out the range of pressure of equivalent in the 200N-250N scope by pressure detection.
Damping structure of the present utility model not only can be stablized the paper road, but also can reduce the fluctuation of average size by stablizing packaging material length, reduces capacity extreme difference scope; This damping structure is applied to the paper guiding roll of Lilezhen bottle placer, increases rotary resistance, realizes the stability that paper guiding roll rotates, and prevents that paper road sideslip is led the paper booster when splicing.
And this damping structure cost of manufacture is low, durable; The resistance that produces is stable, has improved production efficiency.
