Description

Buffer device of elastic tape

Technical Field

The invention relates to the technical field of tape winding and unwinding, in particular to a buffer device of an elastic tape.

Background

At present, a problem generally exists in the process of winding and unwinding an elastic tape, namely, the elastic tape is provided with elastic stretchability, so that the synchronous property of unwinding and winding is often poor, and the elastic tape is often excessively stretched to cause irreversible damage and then bad. The existing devices have no automated equipment that can solve this problem for a while. The invention patent of China with the publication number of CN213976473U provides a macromolecular monofilament rolling buffer device, which comprises a supporting frame, wherein a bottom plate is arranged on the supporting frame, a stand column is connected on the bottom plate, a top plate is connected on the stand column, a plurality of vertical rods are connected between the bottom plate and the top plate, lifting blocks with macromolecular monofilament through holes are connected on the vertical rods in a sliding manner, and an elastic device is connected between the lifting blocks and the top plate or the bottom plate. When the device is used, the polymer monofilaments coated with the PVC material sequentially pass through the polymer monofilament through holes on the lifting blocks, the elastic device between the lifting blocks and the top plate drives the lifting blocks to move upwards, and the elastic device between the lifting blocks and the bottom plate drives the lifting blocks to move downwards so as to tension the polymer monofilaments. When the polymer monofilaments are tensioned, part of the polymer monofilaments passing through the lifting block are straightened, and a certain length is released, so that the polymer monofilaments are prevented from being broken; when the polymer monofilament is too loose, the lifting block tightens the polymer monofilament and accommodates the polymer monofilament for a certain length, so that unsmooth winding is avoided. The embodiment realizes tightness adjustment through free adjustment of the lifting block, and although the lifting block can be prevented from being excessively pulled to a certain extent, the lifting block is poor in stability, can not realize linkage with unreeling and reeling, and still can not guarantee the buffering effect. And for the length calculation of material area, detect mainly through the sensor now, but for the elastic coiled tape, because the elastic coiled tape can be elongated for the detection of sensor inefficacy, unable detection actual length makes the defect that the length is different when rolling.

The upper computer 14 may be a control chip or a PLC capable of processing data, such as a single chip microcomputer, and is used for transmitting linkage instructions to the unreeling device 15, the reeling device 16, and the material belt length calculating component. When the unreeling device 15 stops unreeling (the unreeling device 15 can unreel after the unreeling device 15 needs to obtain the unreeling instruction at the rear end, otherwise excessive unreeling is caused, so that the elastic tape is loosened), the unreeling device 16 starts to be fed back to the upper computer 14 (the upper computer 14 is informed of the start of reeling), since one end of the elastic tape is already unreeled onto the buffer wheel set and the material tape length calculating component, during the continuous reeling of the unreeling device 16, the elastic tape in the buffer wheel set is firstly reeled, under the pulling of the elastic tape by the reeling device 16, the elastic tape close to the reeling device 16 is rapidly pulled, but the elastic tape close to the unreeling device 15 is still not pulled due to elasticity, so that the unreeling device 15 is not started, at this time, the buffer wheel set can receive a pulling force due to the fact that the elastic tape close to the reeling device 16 is pulled, when the upper limit of the travel is lifted, the fact that the elastic coiled tape at the rear end is rapidly coiled is described, the first sensor senses the buffer wheel set and then feeds back to the upper computer 14, the upper computer 14 drives the driver to control the traction roller to rotate so as to pull and advance the elastic coiled tape at the front end, the buffer wheel set of the elastic coiled tape at the rear end is gradually lowered again, the buffer wheel set of the elastic coiled tape at the front end is lifted, the corresponding first sensor detects and feeds back to the upper computer 14, the upper computer 14 transmits an uncoiling instruction to the uncoiling device 15, the uncoiling device 15 uncoils, the buffer wheel sets of the elastic coiled tape at the front end and the rear end are detected by the second sensor after descending to the lower limit of the travel, and the second sensor feeds back to the upper computer 14, and coiling and uncoiling are achieved through linkage before and after the second sensor.

The present embodiment avoids wrinkling by providing the first flattening assembly 10 and the second flattening assembly 11 to flatten the elastic webbing during the advancing process.

The working principle of the embodiment of the invention is as follows: when the winding is performed, the elastic coiled tape at the rear end of the third buffer wheel set 5 is wound and propelled, then the third buffer wheel set 5 is lifted, after the third buffer wheel set 5 is lifted to the upper limit of the travel, the corresponding first sensor detects and feeds back the third buffer wheel set 5 to the upper computer 14, the upper computer 14 starts the second material tape length calculation assembly 7 to propel the elastic coiled tape in the second buffer wheel set 4, after the second buffer wheel set 4 is lifted to the upper limit of the travel, the corresponding first sensor detects and feeds back the first sensor to the upper computer 14, after the first buffer wheel set 3 is lifted to the upper limit of the travel, the upper computer 14 is linked to unwind the first sensor, after the unwinding device 16 stops unwinding, the unwinding device 15 continues to unwind until the first buffer wheel set 3, the second buffer wheel set 4 and the third buffer wheel set 5 are all lowered to the lower limit of the travel and the second sensor detects. The length of the material belt is calculated according to the rotation circumference conversion mode in the advancing process of the first material belt length calculating assembly 6 and the second material belt length calculating assembly 7 to the elastic coiled belt, so that inaccuracy caused by detecting the length through a sensor is effectively avoided, and accurate length counting is realized.
