Detailed Description
The following describes the present invention in further detail with reference to the accompanying drawings.
In the following detailed description of the embodiments of the present invention, for the sake of clarity of the structure of the present invention, it is to be understood that the structure shown in the drawings is not drawn to scale, and is partially enlarged, deformed and simplified, and therefore the present invention is not limited thereto.
In the following embodiments of the present invention, please refer to fig. 1-2, in which fig. 1-2 are schematic structural views of a length control device for unwinding a coarse screen according to a preferred embodiment of the present invention; fig. 1 is a schematic perspective view of the device, and fig. 2 is a schematic side view of the device. As shown in fig. 1-2, the utility model discloses a length control device for coarse mesh unreels can set up on coarse mesh material loading station, and the device can include: the clamping mechanism, the unreeling mechanism, the limiting mechanism, the base 2 and the like. Wherein, fixture, unwinding mechanism and stop gear all set up on base 2.
Please refer to fig. 1-2. The coarse screen 1 is wound on a reeling core 11. The clamping mechanism is used for rotationally clamping the winding core 11 from two ends of the winding core 11.
As a preferred embodiment, the clamping mechanism may be provided with a pair of rotating jaws for clamping the two ends of the reeling core 11.
Further, the clamping jaw can be provided with an air expansion shaft 6, and the two ends of the winding core 11 can be clamped by controlling the expansion of the air expansion shaft 6 through air pressure.
The two air inflation shafts 6 are rotatably arranged on one corresponding supporting roller 7 respectively. The support rollers 7 may be mounted on the base 2. Thus, when the coarse web 1 wound around the winding core 11 is subjected to a traction force (tension, pressure, tension, etc.) at its front end, the winding core 11 and the support roller 7 are driven to rotate passively on the base 2, so that the coarse web 1 is continuously pulled out from the winding core 11.
Please refer to fig. 1-2. The unwinding mechanism is configured to continuously press the surface of the coarse screen 1 between the front end of the coarse screen 1 (which may be fixed by a preceding station) and the winding core 11 through the moving portion 10 provided therein, so that the coarse screen 1 is passively unwound from the winding core 11.
As a preferred embodiment, the unwinding mechanism may be vertically provided with a cylinder 4, and the moving portion 10 is a cylinder rod 10 provided on the cylinder 4.
Further, a pressing roller 5 may be provided at a lower end portion of the cylinder rod 10 to perform rolling pressing on the coarse mesh 1, thereby preventing damage to the coarse mesh 1.
The cylinder 4 may be provided on a bracket 8, and the bracket 8 may be provided on the base 2. The bracket 8 can adopt a horizontal form; in order to maintain the stability of the cylinder 4 when it is pressed down, a balance bar 9 may be provided on the bracket 8 at both sides of the cylinder 4. The upper end of the balance rod 9 penetrates through the horizontal bracket 8 in a sliding mode to form sliding fit with the bracket 8, and the lower end of the balance rod 9 and the end portion of the cylinder rod 10 are connected with the two ends of the pressing roller 5 in a rotating mode through a connecting rod. Thus, the two balance rods 9 can move synchronously under the driving of the cylinder rod 10, thereby effectively ensuring the balance stability during pressing.
Please continue to refer to fig. 1-2. The limiting mechanism comprises a pair of limiting rods 3 which are transversely positioned below the coarse screen 1 and arranged in parallel.

The stopper rod 3 has a preset distance (height) from the stroke of the cylinder rod 10 (cylinder 4) for defining the length of the coarse wire 1 to be paid out.
As a preferred embodiment, the limiting rod 3 may adopt a rod-shaped limiting roller structure, and both ends of the limiting roller 3 may be connected with the base 2 through connecting members.
Further, a plurality of mounting holes for adjusting the mounting height of the connecting piece can be further arranged on the base 2 so as to adjust the height of the limiting roller 3, thereby realizing the adjustment of the preset distance between the travel of the limiting rod 3 and the cylinder rod 10 and adapting to the cutting requirements of the coarse nets 1 with different lengths.
The utility model discloses the device during operation is earlier according to the longest dimension settlement cylinder 4 strokes of thick net 1. Then, the cylinder rod 10 of the control cylinder 4 extends to drive the pressing roller 5 to press downwards. The coarse screen 1 is unreeled into a V shape under the limitation of the two limiting rollers 3. The cylinder 4 is extended to the bottom (stroke) and then retracted, so that the coarse mesh 1 forms a V shape. The length of the V-shaped coarse net 1 is larger than that of the cut coarse net 1.
After the cylinder 4 is retracted, the coarse net 1 is pulled away by the clamping jaws of the previous station for cutting. After cutting, no matter whether redundant coarse nets 1 exist or not, the air cylinder 4 finishes extending and retracting actions again, and the enough unreeling length is guaranteed each time.
Therefore, the unwinding is carried out once before the coarse screen 1 is cut every time, and the coarse screen 1 is guaranteed to have allowance every time. Meanwhile, when unreeling for the second time, the coarse screen 1 which is not used up for the first time is unreeled again, so that accumulation and overlapping can be avoided.
