Abstract

The utility model discloses a rewinder with tension control. The rewinder with the tension control comprises a rack, a power transmission system, a control system, a back-up roll, a paper winding roll, an unwinding shaft and a tension roller group, wherein the back-up roll, the paper winding roll, the unwinding shaft and the tension roller group are all mounted on the rack in a rotary mode, the power transmission system is connected with the control system, and the power transmission system drives the back-up roll and the paper winding roll to rotate. The rewinder with the tension control is characterized in that a tension sensor is arranged on the tension roller group, and the tension sensor is connected with the control system. Compared with the prior art, the rewinder with the tension control has the advantages that by means of the surface speed difference between the unwinding shaft and the back-up roll, paper web tension is formed, actual paper web tension is detected by the tension sensor, set paper injection tension is achieved, then the control mode of an unwinding machine motor is switched automatically, automatic switch of speed control and torque control is achieved, operation steps are reduced, and production efficiency is improved.

Description

The rewinding machine that belt tension is controlled
Technical field
The utility model relates to the rewinding machine that a kind of belt tension is controlled.
Background technology
The unreeling shaft of the papermaking rewinder of main flow is all that the brake power generating machine is controlled at present.The motor of unreeling shaft (be designated hereinafter simply as and unreel motor) mainly contains two kinds of modes: 1, speed is controlled; 2, torque is controlled.When paper injection, unreeling motor is that speed is controlled, and puts forward paper, and the handled easily work is introduced the rewinding shaft backing roll with paper web; After drawing upper paper, unreel motor and should be torque control, pull back paper, and calculate corresponding torque according to the tension gauge that arranges, make paper web have some tension.
After paper web is introduced backing roll, need in time by conversion operations, the mode that unreels motor to be converted to torque and control, use the mode of calculating electromagnetic force to control and unreel motor, keep tension force.If operate untimelyly, because the diameter measurement error that unreels, the superficial velocity of rewinding backing roll and unreeling shaft is inconsistent, makes web tension excessive or too small, easily causes the paper injection paper that breaks.And need to rely on the opportunity of conversion operations rewinding operative employee's proficiency to grasp, and increased difficulty and the intensity of operation, be unfavorable for the raising of rewinding machine production efficiency.
The utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and a kind of reasonable in design is provided, and can automatically control and realize controlling conversion, prevent the rewinding machine of the belt tension control of disconnected paper.
The technical scheme in the invention for solving the above technical problem is: the rewinding machine that this belt tension is controlled, comprise frame, power drive system, control system, backing roll, winding roll, unreeling shaft and jockey pulley group, backing roll, winding roll, unreeling shaft, jockey pulley group all are rotatably installed on frame, the described Power Train control system of unifying connects, described power drive system drives backing roll, winding roll rotates, it is characterized in that: on described jockey pulley group, tension pick-up is set, described tension pick-up is connected with control system.
As preferably, jockey pulley group described in the utility model comprises the first jockey pulley, the second jockey pulley, the 3rd jockey pulley, and the first jockey pulley, the second jockey pulley, the 3rd jockey pulley are successively set between backing roll and unreeling shaft.
As preferably, tension pick-up described in the utility model is arranged on the second jockey pulley.
The utility model compared with prior art, have the following advantages and effect: the poor formation web tension of superficial velocity that utilizes unreeling shaft and backing roll, and detect the paper web actual tension by tension pick-up, after reaching setting paper injection tension force, automatically conversion unreels the mode of motor, realize the automatic conversion that speed is controlled and torque is controlled, reduced control step, improved production efficiency.
Description of drawings
Fig. 1 is structural principle schematic diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Referring to Fig. 1, the rewinding machine that the present embodiment belt tension is controlled, comprise frame, power drive system, control system, backing roll 1, winding roll 2, unreeling shaft 3 and jockey pulley group, backing roll 1, winding roll 2, unreeling shaft 3, jockey pulley group all are rotatably installed on frame, the described Power Train control system of unifying connects, described power drive system drives backing roll 1, winding roll 2 rotates, and on described jockey pulley group, tension pick-up 4 is set, and described tension pick-up 4 is connected with control system.The jockey pulley group comprises that the first jockey pulley 5, the second jockey pulley 6, the 3rd jockey pulley 7, the first jockey pulleys 5, the second jockey pulley 6, the 3rd jockey pulley 7 are successively set between backing roll 1 and unreeling shaft 3.Tension pick-up 4 is arranged on the second jockey pulley 6.
The utility model is when paper injection, and as shown in Figure 1, the superficial velocity of paper web 8 and unreeling shaft 3 is identical is all V1, and the superficial velocity of backing roll 1 is V2.After paper web 8 was introduced backing roll 1, because V1<V2 paper web is strained gradually, it is large that the tension force of paper web 8 becomes.After the tension force of paper web 8 surpassed the setting tension value, control system was through delay judgement, and control system is automatically changed power drive system control and become torque control from speed control method.
Above content described in this specification sheets is only to the explanation of the utility model example.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from the content of the utility model specification sheets or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
