SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an automatic blowing device to prior art's not enough, this automatic blowing device has solved the existence of current gauze mask surface fabric material frame: the conveying speed of the mask fabric can not be controlled.
In order to achieve the purpose, the utility model is realized by the following technical scheme: automatic blowing device, including vertical frame, the pulley is installed to vertical frame's bottom, installs the fixed plate on the vertical frame, and the motor is installed to one side of fixed plate, and the drive roll is installed to the opposite side of fixed plate, and motor drive roll, vertical frame install a plurality of fixed rollers, and vertical frame installs the movable roll.
The fixed roller is parallel to the driving roller.
The vertical frame is provided with a bearing, the bearing is connected with a connecting rod, and the connecting rod is provided with a movable roller.
The beneficial effects of the utility model reside in that: through the cooperation of activity roller and fixed roll, make the gauze mask surface fabric keep conveying speed, can not produce the folding phenomenon of gauze mask surface fabric, the gauze mask surface fabric can directly be placed on the drive roll, improves production efficiency simultaneously.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
See fig. 1, the utility model discloses automatic blowing device includes: the device comprises a vertical frame 1, pulleys 2, a fixing plate 3, a motor 4, a driving roller 5, a fixing roller 6, a bearing 7, a movable roller 8, a connecting rod 9, an external frame 10 and a switching frame 11.
The utility model discloses a pulley 2 is installed to vertical frame 1's bottom, installs fixed plate 3 on vertical frame 1, and motor 4 is installed to one side of fixed plate 3, and drive roll 5 is installed to the opposite side of fixed plate 3, and motor 4 drives drive roll 5, and the gauze mask surface fabric can directly place on drive roll 5, improves production efficiency.
The utility model discloses a vertical frame 1 installs a plurality of fixed rollers 6, and fixed roller 6 is on a parallel with drive roll 5.
The utility model discloses a bearing 7 is installed to vertical frame 1, connecting rod 9 has been cup jointed to bearing 7, connecting rod 9 is perpendicular with bearing 7's center pin, install movable roller 8 on the connecting rod 9, movable roller 8 is on a parallel with drive roll 5, connecting rod 9 can rotate by relative bearing 7, when the gauze mask surface fabric removes from movable roller 8, because movable roller 8 can move about, therefore, movable roller 8 can make gauze mask surface fabric and fixed roll 6 cooperation, keep the tension of gauze mask surface fabric, thereby it is controllable to realize speed, therefore the folding phenomenon because speed mismatch and emergence when the conveying can not appear.
The utility model discloses an install angle sensor on connecting rod 9, can be in order to know connecting rod 9's rotation angle, angle sensor connection control board, motor 4 connection control board feeds back the rotation angle signal of connecting rod 9 to the control panel through angle sensor, again by control panel control motor 4's speed to reach the effect of pendulum range control of activity roller 8 in certain extent and balanced cloth tension. The control panel has a preset control program, which is not described in detail herein, and is installed on the vertical frame 1.
The utility model discloses a fixed roll 6 is located the top of activity roller 8, and a set of activity roller 8 of general 6 configurations of a set of fixed roll, and the gauze mask surface fabric removes fixed roll 6 behind activity roller 8.
The utility model discloses a fixed roll 6, activity roller 8 are located the next door of drive roll 5 respectively.
The utility model discloses it has four group's motors 4, four group's drive rolls 5, four group's movable roll 8 to show in the figure, can use as required.
The utility model discloses for current material frame's advantage lies in: 1. the motor 4 provides auxiliary power for the transmission of the mask fabric, and the fixed roller 2 and the fixed roller 6 are matched with the movable roller 8, so that the speed of the mask fabric can be kept.
Of course, the above-mentioned embodiments are only preferred examples of the present invention, and not intended to limit the scope of the present invention, so that all equivalent changes or modifications made by the structure, features and principles described in the claims of the present invention should be included in the claims of the present invention.
