Abstract
The utility model discloses a kind of casting films winder, comprise rolling frame, described rolling frame is provided with disk, and described disk is provided with rolling main shaft, described rolling main shaft has connected rolling volume core, and described rolling main shaft is controlled by driven by servomotor by driving device.The utility model speed setting range surpasses more than 100 times, meets the Production requirement that different linear velocities are different with film thickness.
Description
Technical field
The utility model relates to the technical field of casting films manufacturing line, more specifically, relates to a kind of casting films winder.
Background technology
At present, the rolling scope of the take-up diameter of the winder of domestic casting films manufacturing line differs 6 times of left and right, and the variation range of film thickness is 6 times of left and right, so the rolling frequency of winder need to remain on 30 times of above speed adjustable ranges, and domestic casting films winder is all controlled with variable-frequency motor, in the time of film production, wind-up roll footpath becomes large along with the increase of rolling film, the cireular frequency of rolling is in continuous variation range, and common variable-frequency motor is due to the character of electric machine structure, output torque constantly tails off, and speed adjustable range is also 10 times of left and right, can not meet 30 times of above variation ranges of curtain coating rolling speed far away, so, the winder of this common variable-frequency motor can only be stablized when high-speed cruising, and linear velocity is unstable during lower than 60m/min, often there is the phenomenon of reporting to the police in winder, cause other productions of casting films manufacturing line not out, reduced production efficiency, increased productive costs.Therefore, must develop performance-oriented winder, to meet the demand of production increase day by day.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of casting films winder, and it can solve transmission variable-frequency motor, and because wind-up roll footpath becomes large, output torque tails off, the little problem that causes winder fluctuation of service of speed adjustable range.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A casting films winder, comprises rolling frame, and described rolling frame is provided with disk, and described disk is provided with rolling main shaft, and described rolling main shaft has connected rolling volume core, and described rolling main shaft is controlled by driven by servomotor by driving device.
The speed adjustable range of the servomotor that the utility model adopts is over 100 times, met current curtain coating rolling speed in more than 30 times variation ranges, utilize the variable-frequency motor of the alternative traditional casting films winder of servomotor, meet the product demand of any thickness specification.
Described rolling main shaft and rolling volume core are positioned at same axis, and rolling volume core is rotated by rolling main shaft drives.By rolling main shaft drives rolling volume core, rotate and carry out rolling.
Described driving device is the synchronizing wheel driving device of being located in rolling frame, described synchronizing wheel driving device comprises the first synchronizing wheel, the second synchronizing wheel and driving band, described the first synchronizing wheel is connected with servomotor, described the second synchronizing wheel is connected with rolling main shaft, and described the first synchronizing wheel is connected by driving band with the second synchronizing wheel.
Particularly, the first synchronizing wheel is arranged on the output shaft of servomotor, the second synchronizing wheel is arranged on rolling main shaft, both connect by driving band, when servomotor output shaft drives the first synchronizing wheel to rotate, the first synchronizing wheel drives the second synchronizing wheel to rotate by driving band, and the second synchronizing wheel drives rolling main shaft to rotate by key bar.
Compared with prior art, the beneficial effects of the utility model are: speed setting range surpasses more than 100 times, meet the Production requirement that different linear velocities are different with film thickness, solved traditional variable-frequency motor output torque few, adjust the low problem of speed range, promote the performance of casting films manufacturing line, enhanced productivity, avoided the phenomenon that rolling is interrupted to occur.
Accompanying drawing explanation
Fig. 1: structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment:
As shown in Figure 1, a kind of casting films winder, comprise rolling frame 6, described rolling frame 6 is provided with disk 5, described disk 5 is provided with rolling main shaft 4, described rolling main shaft 4 has connected rolling volume core 3, and described rolling main shaft 4 has connected the synchronizing wheel driving device 2 of being located in rolling frame 6, and described synchronizing wheel driving device 2 is driven and controlled by servomotor 1.
Described synchronizing wheel driving device 2 comprises the first synchronizing wheel (not marking in figure), the second synchronizing wheel (not marking in figure) and driving band (not marking in figure), described the first synchronizing wheel is connected with servomotor 1, described the second synchronizing wheel is connected with rolling main shaft 4, and described the first synchronizing wheel is connected by driving band with the second synchronizing wheel.
Principle of work of the present utility model: servomotor 1 drives 2 transmissions of synchronizing wheel driving device, thus drive rolling main shaft 4 to rotate, and rolling main shaft 4 drives rolling volume core 3 to do rolling campaign; Film is along with the rolling round and round of rolling volume core, rolling coil diameter also constantly increases, and the state of cireular frequency in continuous variation, cireular frequency is by tailing off greatly, the control of the wide speed regulating range by servo control system, has met the requirement that cireular frequency constantly changes, and the output torque of servomotor is invariable, make rolling in stabilized conditions, do not occur the phenomenon of disconnected volume; When film thickness is different, the change of line speed scope in wind-up roll footpath is also different, and the wind-up roll of controlling in servomotor also can meet the requirement of this velocity variations.
