Description

Full-automatic film winding machine

Technical Field

The invention belongs to the technical field of film production equipment, and particularly relates to a full-automatic film winding machine.

Background

Films are widely used as a very important packaging material in people's daily lives. For film manufacturers, after the film is formed, the film must be rolled into a bundle shape by a corresponding film rolling machine, so as to be convenient to place and transport.

In the prior art, in the film winding process, the film wound on the winding roller is gradually thickened, so that the winding roller needs to be replaced in order to ensure that the winding roller can normally wind the film, and the film is wound on a plurality of winding rollers. In the prior art, a film is generally wound by a film winding machine, the traditional winding machine generally has only one winding roller, when the diameter of the film wound by the winding roller reaches a set value and the winding roller needs to be replaced, the winding roller is required to be stopped in a normal operation mode, and then the winding roller after winding is manually taken down by a worker and the hollow winding roller is arranged, so that winding operation is performed again. In the traditional winding device, a rubber roller is generally arranged on one side of the winding roller, and is abutted against the winding roller, firstly, the rubber roller can drive the winding roller to rotate through friction, so that the winding of the film is realized; secondly, can guarantee to wind and can not appear the bubble in the film on the wind-up roll, consequently adopt the manual work to take out the mode comparatively complicated with the wind-up roll, and when changing the wind-up roll again and install new wind-up roll at every turn, still need spend time to adjust the cooperation relation between wind-up roll and the rubber roller, such rolling change mode consumes the manpower, has the danger of manual work film breaking change operation, causes the waste of film and the bad of product easily, leads to work efficiency low.

In order to not influence the normal running of winding work in the process of disassembling and assembling the winding rollers, at least two groups of winding rollers are usually arranged on one winding device to work alternately, but each group of winding rollers are required to be driven by power and cannot interfere with each other, the common method at the present stage is to independently arrange a driving mechanism on each group of winding rollers, so that the equipment cost is obviously increased, and the weight is increased due to the fact that the driving mechanism is arranged on each winding roller, so that the winding rollers are hard to switch.

In two patents with the authorized bulletin numbers of CN 110844656B and CN 110844655B, a structure of placing one or more backup wind-up rolls on a winding machine is proposed, the wind-up rolls are replaced by using a rotating disc, and the wind-up rolls after winding are conveyed out by using a conveying plate, so that a certain degree of automatic operation is realized, but part of the operations are as follows: the replacement and placement of the backup wind-up roll still requires manual operation.

For the existing film winding machine, the automation degree and the working efficiency of the film winding machine still need to be further improved.

The side wall of carousel 4 is equipped with puts the roller groove, put the roller groove on the carousel 4 and be the eight character shape groove, when reserve wind-up roll 31 place in put the roller inslot, reserve wind-up roll 31's both ends are placed in the recess of frame 1 both sides placing plate 24.

The principle of operation of the present invention will now be described as follows: when it is necessary to wind up the film, one winding roller 3 is first placed in the groove at the top of the second support 8, i.e. the winding position, and the other standby winding roller 31 is placed in the groove on the placing plate 24, i.e. the standby position, as shown in fig. 1. Because the wind-up roller 3 is propped against the rubber roller 2, the rubber roller 2 rotates and synchronously rotates the wind-up roller 3 by virtue of friction force, and the wind-up roller 3 does not need to be provided with a rotating mechanism independently, the energy saving and environment protection are realized, as the film wound by the wind-up roller 3 is thicker and thicker, the wind-up roller 3 can be slowly jacked up from the groove at the top of the second support 8, but the wind-up roller 3 and the rubber roller 2 are always kept in a propped state, and the winding can be continued.

After the winding is completed, the second support 8 is driven to rotate through the second support cylinder 7 and is close to the first support 6, the wound winding roller 3 is placed in a groove at the top of the first support 6, namely a conveying position, and then the second support 8 is reset. Simultaneously, the turntables 4 on two sides of the rubber roller 2 are driven to rotate, and the standby winding roller 31 synchronously rotates in the roller placing groove on the side wall of the turntables 4 and falls into the groove on the top of the second support 8. At this time, the cutter assembly 20 is driven to slide on the cutting slide rail 19 to cut the film, the winding work of the winding roller 3 is completed, and the standby winding roller 31 starts to wind up, as shown in fig. 2.

When wind-up roll 3 and reserve wind-up roll 31 switch, first support 6 stretches to putting the flat state from vertical state under the control of first support cylinder 5, unload the material level promptly for wind-up roll 3 is put subaerial, like fig. 3, and the manual handling of being convenient for or directly utilize mechanical handling such as fork truck, this process need not additionally to set up the power supply, has not only reduced equipment cost, and alleviateed workman's work load, has saved the human cost. After the film on the wind-up roller 3 is disassembled manually or mechanically, the empty wind-up roller 3 is placed in a groove at the top of the first support 6, the first support 6 is pulled to rotate through the first support cylinder 5, and the wind-up roller 3 is reset to a conveying position from a discharging position, namely, the state shown in fig. 2. At this time, the driving wheel 10 and the driven wheel 12 are driven to rotate, the U-shaped movable frame 13 horizontally moves to the top of the transmission position, then the U-shaped movable frame extends out through the lifting cylinder 14, the clamping plate 16 and the grabbing claw 17 are aligned with the two ends of the wind-up roller 3, the grabbing cylinder 18 extends out to push the grabbing claw 17 to rotate, the two ends of the wind-up roller 3 are grabbed, the lifting cylinder 14 is controlled reversely, the wind-up roller 3 is grabbed, as shown in fig. 4, the driving wheel 10 and the driven wheel 12 are reversed, the wind-up roller 3 is conveyed to the top of the standby position, the lifting cylinder 14 extends out again, the wind-up roller 3 is placed in the standby position for standby, as shown in fig. 5, switching between the wind-up roller and the standby wind-up roller is automatically completed through cyclic reciprocation, manual operation is not needed, and the degree of automation is high.

According to the invention, through the plurality of support cylinders and the supports, the automatic conveying of the winding roller after winding is finished is realized, the discharging and the conveying are convenient, and through the conveying device and the grabbing device, the automatic switching of the winding roller and the standby winding roller is realized, the manual operation is not needed, the shutdown operation is also not needed, the workload of workers is reduced, and the working efficiency is improved.
