Description
Technical Field
The utility model belongs to the technical field of plastic film roll production and processing, and particularly relates to an automatic film roll weighing mechanism of a film surface winding device.
Background
After the film is produced, the film is coiled into a film coil by being sleeved on a paper core tube of a coiling shaft. The first type is center rolling, as the name implies, the film roll rotating power is directly from the rolling shaft at the center of the film roll, and the rolling shaft is directly driven by the rolling motor; the second type is surface winding, and as the name suggests, the power of the film roll rotation comes from a surface friction roller contacted with the surface of the film roll, the surface friction roller is pressed on the surface of the film roll and carries out surface friction rubbing on the film roll, and the surface friction roller is directly driven by a friction roller motor.
The film winding device for driving the film roll to rotate by utilizing surface friction is called a film surface winding device. In the film surface winding device, the surface friction roller is fixed, in the winding process, along with the continuous increase of the diameter of the film roll, as shown in fig. 1 and 2, the film roll 8 and the winding shaft 11 must continuously move backwards, for this reason, both ends of the winding shaft 11 are generally mounted on the horizontal guide rail 3, so that in the winding process, the film roll 8 and the winding shaft 11 can smoothly retract, and the retraction direction is shown as an arrow v in fig. 1, namely, the state shown in fig. 1 is retracted to the state shown in fig. 2.
When the film wound by the winding shaft at the winding position reaches a set length, a new winding shaft needs to be replaced, and the process is called reel replacement. After the reel change is completed, the old reel 11 (together with the film roll) is moved along the horizontal guide rail to the unreeling position (the position of the right end section of the horizontal guide rail in fig. 3), and the unreeling work is performed, and the film roll 11 is removed from the reel. During the unreeling process, since the film upstream of the production line is still continuously transported, and the unreeling operation needs a period of time, another reeling shaft 12 is needed for reeling during the unreeling process, which means that the whole film surface reeling device needs to be provided with two reeling shafts, one of which is located at the reeling position for reeling, and the other is used for standby. The material of the winding shaft is solid metal, the weight is large, and the winding shaft is not a standard component, so that the weight of the two winding shafts is not exactly equal, and the weight difference of the two winding shafts is not small.
In addition, each time a roll of film is produced, the roll of film also needs to be weighed. The film roll weighing process of the existing film surface winding device is as follows: the film roll is transferred to the carrying trolley from the right end of the horizontal guide rail, then the carrying trolley runs beside the weighing mechanism, then the film roll is carried to the weighing mechanism for weighing, and then the film roll is carried back to the carrying trolley, so that the film roll is very heavy, and the process is very inconvenient; in addition, the weighing result obtained in the above-mentioned weighing process includes the weight of the winding shafts, and although the weight of the winding shafts can be subtracted when calculating the net weight of the film roll, as described above, the weights of the two winding shafts are different, and the weight of the winding shafts made of solid metal occupies a small proportion in the film roll, so that the net weight of the film roll cannot be accurately and automatically obtained.

The aim can be achieved according to the following scheme: the film roll automatic weighing mechanism of the surface friction winding device comprises a surface friction roller and a winding shaft, wherein the axial direction of the surface friction roller is transversely referred to, and a left horizontal guide rail and a right horizontal guide rail for supporting the end part of the winding shaft are arranged beside the surface friction roller; the vertical sliding block is characterized in that a vertical sliding block capable of vertically sliding is arranged at the longitudinal middle section of each horizontal guide rail, the top surface of the vertical sliding block is a horizontal plane, and each vertical sliding block is correspondingly provided with a vertical oil cylinder for driving the vertical sliding block to vertically move; a supporting block is arranged on the outer side of the vertical sliding block of each horizontal guide rail, a weighing sensor is arranged below the supporting block, and the supporting block is pressed on the weighing sensor; the top of the supporting block is provided with an arc-shaped notch, the front side and the rear side of the arc-shaped notch are high, the middle of the arc-shaped notch is sunken downwards, and the vertical positions of the left end and the right end of the arc-shaped notch are flush with the vertical position of the top surface of the horizontal guide rail; when the piston rod of the vertical oil cylinder is completely contracted downwards, the vertical position of the top surface of the vertical sliding block is lower than the low point of the middle part of the arc-shaped notch of the supporting block; when the piston rod of the vertical oil cylinder is completely lifted upwards, the vertical position of the top surface of the vertical sliding block is flush with the vertical position of the top surface of the horizontal guide rail; the weighing sensors on the outer sides of the sliding blocks of the two horizontal guide rails are respectively connected to the central processing unit.
The term "outside of the slider" refers to the left side of the slider on the left horizontal rail; the slider on the right horizontal rail is to the right of the slider.
The winding shafts are provided with two winding shaft wheel flows which are used as a main winding shaft and a standby winding shaft, the end part of one winding shaft is provided with a magnet block, and a magnetic induction device is correspondingly arranged beside one supporting block; a central processor is also provided, to which the magnetic induction device is also connected.
The utility model has the following advantages and effects:
1. after the film roll is rolled, the rolling shaft moves along the horizontal guide rail from the rolling position to the unreeling position, in the process, when the end part of the rolling shaft reaches the arc-shaped notch of the supporting block, the end part of the rolling shaft slides into the arc-shaped notch smoothly, the piston rod of the vertical oil cylinder is completely contracted downwards, and the vertical position of the top surface of the vertical sliding block is lower than the lower point of the middle part of the arc-shaped notch of the supporting block, so that the weight of the whole film roll is supported on the supporting block and is transmitted to the weighing sensor, and the weighing of the film roll is realized; after weighing is completed, the piston rod of the vertical oil cylinder is completely lifted upwards, the vertical position of the top surface of the vertical sliding block is flush with the vertical position of the top surface of the horizontal guide rail, so that the vertical sliding block jacks up the end part of the winding shaft to enable the end part of the winding shaft to be separated from the arc-shaped notch of the supporting block, and then the end part of the winding shaft can be continuously moved to the coil unloading position at the other end of the horizontal guide rail. From the above, the weighing process of the film roll is convenient.
2. The weight of the two winding shafts can be accurately known in advance and data can be input into the central processing unit, and the magnetic induction device can identify whether the winding shaft of the film roll positioned on the supporting block is provided with the magnet or not, so that the central processing unit can identify which winding shaft is according to the signal of the magnetic induction device, and the central processing unit can automatically and accurately obtain the net weight of the film roll as long as the weight of the winding shaft is subtracted by the reading of the weighing sensor.
