The swing rod 1-1 is made of a non-metal material with a round and smooth outer surface, and the outer surface is in a rod shape with a spherical front end. The side plates 1-2 are also made of non-metal materials, and the outer surfaces of the side plates are round and smooth, so that smooth sliding of the film is facilitated. One end of the swing rod 1-1 is a free end, the other end of the swing rod is hinged on the side plate 1-2 through a pin, and an elastic element is arranged between the swing rod 1-1 and the side plate 1-2 to ensure that the swing rod 1-1 is kept in a natural horizontal state. The shaft sleeves 1-8 are provided with set screws which can penetrate through the shaft sleeves 1-8 to be in contact with the end shafts 1-7 in the shaft sleeves 1-8.

As shown in figures 2 and 3, the upper part of the upper end shaft 1-7 and the lower part of the lower end shaft 1-7 are both provided with a driving shaft 2, the driving shaft 2 is sleeved with a rubber roller 2-1, and the driving shaft 2 drives the end shaft 1-7 to rotate through the rubber roller 2-1. The drive shaft 2 requires external power to drive rotation, with only synchronous and constant rotational motion. The horizontal and vertical directions are usually fixed, and the distance between the two driving shafts 2 is adjusted only when the specification of the film roll 3 is changed, but the horizontal direction has no displacement. The two driving shafts 2 are parallel to each other, arranged with upper and lower plumbs, and the height difference of the inner side is smaller than the height of the elastic film opening device 1. Each rubber roller 2-1 is connected with the driving shaft 2 through a key and rotates at the same rotating speed under the driving of driving equipment. The span of the two rubber rollers 2-1 on the same driving shaft 2 corresponds to the span of the nylon rollers 1-4 on the elastic film opening device 1, and the elastic film opening device 1 is limited and fixed by the 4 rubber rollers 2-1. One end of the film roll 3 is clamped by the elastic film opening device 1 and the driving shaft 2 in the vertical direction, and the two sides of the film roll are opened by the elastic film opening device 1.

Fig. 5 and 6 show the horizontal fixing feature of the film opening elastic mechanism 1 and the driving shaft 2. Since the driving shafts 2 can only rotate, the two degrees of freedom, horizontal and vertical, are limited, so that the elastic membrane opening device 1 is mounted between the two driving shafts 2 to limit the vertical displacement thereof. The specific description is as follows: each side plate 1-2 is correspondingly provided with two end shafts 1-7, each end shaft 1-7 is provided with two bearings, the rubber roll 2-1 corresponding to the driving shaft 2 is arranged on each end shaft 1-7, each end shaft 1-7 is respectively provided with two bearings 1-3 which are contacted with the end shaft, namely the outer circumferential surfaces of 4 bearings 1-3 in total are tangent to the excircle of the rubber roll 2-1. The rubber roller 2-1 limits the vertical displacement of the four bearings 1-3, and can keep the rubber roller 2-1 and the bearings 1-3 in full contact, so that the rubber roller 2-1 can provide uniform friction torque for the film roll 3 in a working state. The displacement between the driving shaft 2 and the elastic film opening device 1 in the horizontal direction is limited by the conical surfaces of the nylon rollers 1-4. An end shaft 1-7 far away from the swing rod 1-1 is provided with a plurality of bearings 1-3, and one side of the nylon roller 1-4 facing the rubber roller 2-1 is a conical surface and is tangent to a fillet of the rubber roller 2-1. Therefore, the two rubber rollers and the two corresponding nylon rollers 1-4 with back to back limit the horizontal displacement of the elastic film opening device 1. The above description can be understood that the rubber roller 2-1 is clamped in a space region formed by four bearings 1-3 and one rubber roller 1-4, and the horizontal and vertical displacement of one corner of the elastic film opening device 1 is limited.

As shown in figure 7, the upper side plate 1-2 and the lower side plate 1-2 are connected together by a pair of spring mechanisms 1-5. The spring mechanisms 1-5 are composed of guide posts, compression springs, spring seats and the like, and are used in pairs. Vertical pressure is applied to the elastic film opening device 1, and the height of the elastic film opening device 1 is reduced under the action of the spring mechanisms 1-5. The elastic opening device 1 then recovers the natural height when the pressure is released. The spring mechanism 1-5 can fulfill two functions. One is to facilitate the quick installation of the elastic opening device 1 between the drive shafts 2. Secondly, when in normal use, the rubber roller 2-1 of the driving shaft 2 continuously rolls the film roll 3 to convey forwards, and the inner wall of the film roll 3 also applies friction torque to the elastic film opening device 1, so that the elastic film opening device 1 tends to be dragged outwards. The spring means 1-5 counteract this tendency by virtue of the self-adaptation of the compression spring.

As shown in fig. 8 and 9, a toggle clamp 1-6 is disposed between a pair of spring mechanisms. When the handle of the elbow clip 1-6 is moved, the push rod of the elbow clip 1-6 can move up and down, and the top dead point is the lowest point of the spring mechanism 1-5 which can be compressed. The function of the spring mechanism is to limit the compression amount of the spring mechanism 1-5, so that the compression amount can be controlled within a certain range. The mounting position of the elbow clamp is adjustable, the extension amount of the push rod is also adjustable, so that the spring mechanisms 1-5 can adapt to a larger compression range, and the elastic die sinking device 1 can adapt to the change of the height dimension of the film roll 3 within a certain range.

As shown in fig. 10, the width of the elastic film-opening device 1 can be freely adjusted to accommodate the change of the width dimension of the film roll 3 within a certain range. Two end shafts 1-7 in the horizontal direction are respectively inserted into a hollow shaft sleeve 1-8, and the width of the elastic membrane opening device 1 is determined by the depth of the insertion. Two fastening screws are respectively arranged at two ends of the shaft sleeves 1-8, and after the insertion depth is determined, the displacement of the end shafts 1-7 can be fixed by locking the fastening screws.

As shown in fig. 11, the mounting feature of the elastic opening device 1. The elastic membrane opening device 1 is pushed horizontally by hand towards the space between the two driving shafts 2, because the span of the two driving shafts 2 is fixed, the spring mechanism 1-5 will be compressed centripetally. After the elastic film opening device 1 is clamped between the four rubber rollers 2-1, the spring mechanism 1-5 tightly pushes the bearing 1-3 and the rubber rollers 2-1 by means of the rebound tendency. The loose elbow clamp 1-6 is pushed upwards, the top dead center of the push rod is locked, the spring mechanism 1-5 is forced to press downwards in the working state, and the maximum compression state is against the top of the push rod. At this point, the installation of the elastic opening device 1 is completed.
