Abstract
A small cutting unwinder is provided, which is more particularly suitable for high speed unwinding of a narrow membrane. The framework of the unwinder is composed by a framework plate, a rear jamming orifice, as well as a front upper support and a lower support; the upper support front end is provided with an unwinding shaft, the lower support front end is provided with two pass wheels; a cylinder is arranged at one side of the unwinding shaft, a brake block is arranged between the unwinding shaft and the cylinder, the cylinder push rod is sustained on the brake block center, and the brake block nestles up against the unwinding shaft head. The cylinder push rod thrust is controlled through controlling the pressure in the cylinder, the push rod pushes the brake block, the brake block is tightly pressed on the unwinding shaft head, thereby controlling the unwinding pulling force of the cylinder push rod. The utility model of membrane rolls rolling up after process with neat end face, which fundamentally doesn't have any membrane waste.
Description
Technical field
The utility model relates to a kind of film unwinding device, and promptly a kind of unreeling machine of cutting for a short time, this machine are particularly useful in a narrow margin that the high speed of film unreels control.
Technical background
In the prior art, the retractable winding apparatus kind of plastic sheeting, BOPP film is a lot, with the utility model approaching be a kind of small-sized unreeling machine of plastic sheeting in a narrow margin, this machine is made up of frame, unreeling shaft and third wheel three parts, frame is by the chucking mouth of frame plate and back thereof, fwd upper bracket and lower bracket constitute, and at the front end of upper bracket a unreeling shaft are installed, and at the front end of lower bracket a third wheel are installed.The plastic film sleeve of rolling is contained on the unreeling shaft of upper bracket, and film is pulled out on unreeling shaft, emits after walking around the third wheel of lower bracket, enters down manufacturing procedure one.
This unreeling machine is not owing to control the rotation of unreeling shaft or third wheel, and their rotation is according to the pulling force size that transmits on the film, freely rotate, thereby rotating speed is sometimes fast and sometimes slow, and the left and right sides amplitude of oscillation is bigger.This mode that unreels is in the processing film process, following one manufacturing procedure after unreeling is to the control difficulty of film, because the tension force that unreels is inhomogeneous, the left and right sides amplitude of oscillation is big, causes the rolling of film irregular, the finished product volume upper film tension difference of harvest is bigger, has a strong impact on the quality of product.This film rolling is used for doing the material of packing other products in commercial production, meeting can't meet the quality requirement because of film rolling self, causes product external packaging undesirable, and the reject rate of packing is higher.
Technology contents
When content of the present utility model provided a kind of unreeling, the tension force of film and the amplitude of oscillation can be effectively controlled cut unreeling machine for a short time.The frame of this machine is identical with rack construction of the prior art, that is: frame is by the chucking mouth of frame plate and back thereof, and fwd upper bracket and lower bracket constitute; Front end at upper bracket is equipped with a unreeling shaft, at the front end of lower bracket a third wheel is installed; Difference from prior art is: in a side of unreeling shaft, a cylinder is installed, between unreeling shaft and the cylinder, a brake facing is installed, the push rod of cylinder withstands on the central authorities of brake facing, and brake facing is pressed close to the spindle nose of unreeling shaft; Lower bracket front end below the frame front end, the third wheel of installation have two.
That adopts said structure cuts unreeling machine for a short time, by the pressure in the control cylinder, make the thrust of cylinder push-rod controlled, push rod promotes brake facing, brake facing is pressed on the spindle nose of unreeling shaft, thereby the unwinding tension of unreeling shaft obtains accurate actv. control, passes through the balance and the buffering of two-stage third wheel again, the film side-play amount of emitting is very little, tension stability.Therefore, the utility model is specially adapted to carry out the processing that unreels of narrow fabric width film, and can mate the high speed cutting machine and unreel processing fast, the film rolling of accepting again after the processing, end face is neat, does not have the film waste substantially.
Description of drawings
Fig. 1 is a side-looking structural representation of the present utility model:
Fig. 2 is a plan structure scheme drawing of the present utility model.
Specific embodiment
As depicted in figs. 1 and 2, a kind of unreeling machine of cutting, the unreeling shaft 1 of this machine are installed in the upper bracket front end of frame front end top, unreeling shaft 1 usefulness bearing seat 3 is fixed on the upper bracket, lower bracket front end below this machine frame front end is equipped with third wheel 2, and third wheel 2 has two; In a side of unreeling shaft 1, a cylinder 5 is installed, between unreeling shaft 1 and the cylinder 5, a brake facing 4 is installed, the push rod of cylinder 5 withstands on the central authorities of brake facing 4, and brake facing 4 is pressed close to the spindle nose at unreeling shaft 1.
The film that the film rolling of installing from unreeling shaft 1 is emitted enters next road manufacturing procedure after walking around two third wheels 2 of its below.
Cylinder 5 and brake facing 4 are used to control the unwinding tension of unreeling shaft 1.Tolerance and air pressure in the control cylinder 5, thrust that just can control cylinder 5 upper push-rods, thus control friction force between brake facing 4 and unreeling shaft 1 spindle nose, thus reach the purpose of the tension force that accurately control unreels.
Claims (2)
1. cut unreeling machine for a short time for one kind, be installed in the upper bracket front end of frame front end top at the unreeling shaft (1) of this machine, unreeling shaft (1) is fixed on the upper bracket with bearing seat (3), lower bracket front end below this machine frame front end is equipped with third wheel (2), it is characterized in that: in a side of unreeling shaft (1), a cylinder (5) is installed, between unreeling shaft (1) cylinder (5), a brake facing (4) is installed, the push rod of cylinder (5) withstands on the central authorities of brake facing (4).
2. the unreeling machine of cutting for a short time as claimed in claim 1 is characterized in that: the lower bracket front end below this machine frame front end, the third wheel of installation (2) has two.
