Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-6: a film side edge flattening device comprises a plurality of groups of film clamping components (not shown in a frame drawing) which are oppositely arranged in a frame, wherein the film clamping components are used for clamping the left and right side edges of a film.

The film clamping assembly comprises a base 1 fixedly installed on the side edge of the rack, wherein the base 1 is composed of an upper splicing member 101 and a lower splicing member 102 (the upper splicing member 101 and the lower splicing member 102 can be connected in a clamping manner, can also be connected in a locking manner, or can be connected in other equivalent connection manners, and are not described herein again). Wherein, the upper splicing member 101 is provided with a first clamping roller 2; under the first clamping roller 2, a rotary base station 3 realizes mutual hinge of the front end of the rotary base station 3 and the lower splicing member 102 through a rotating shaft 301, and a second clamping roller 4 parallel to the first clamping roller 2 is installed at the tail end of the rotary base station 3. The bottom of the lower splicing member 102 is further provided with a pneumatic pushing mechanism 5 capable of pushing the rotary base station 3 to lift upwards, the top of the pneumatic pushing mechanism 5 is in contact with the bottom surface of the rotary base station 3, and under the pushing action of the pneumatic pushing mechanism 5, the rotary base station 3 can rotate by taking the rotating shaft 301 as an axis until the second clamping roller 4 abuts against the first clamping roller 2.

Further, the upper splicing member 101 and the rotary base 3 are respectively provided with a clamping roller mounting groove 6, and the first clamping roller 2 and the second clamping roller 4 are mounted in the corresponding clamping roller mounting grooves 6.

Further, the first clamping roller 2 and the second clamping roller 4 can be fixedly arranged in the clamping roller mounting groove 6 or rotatably arranged in the clamping roller mounting groove 6.

The pneumatic pushing mechanism 5 comprises a piston cylinder 501 locked and fixed at the bottom of the lower splicing member 102, a piston head 502 is movably mounted in the piston cylinder 501, the top of the piston head 502 is in contact with the bottom surface of the rotary base 3, and the piston head 502 can move upwards by introducing air into the piston cylinder 501, so that the rotary base 3 is pushed upwards to rotate, and the first clamping roller 2 is abutted to the second clamping roller 4.

Further, the top of the piston head 502 is formed with a spherical protrusion 5021, and the spherical protrusion 5021 contacts with the bottom surface of the rotary base 3 in a manner similar to a point contact (which helps to concentrate the clamping force and improve the clamping stability).

Considering that in the present design, if the installation position of the piston cylinder 501 is too forward, the spherical protrusion 5021 of the piston head 502 may be pushed against the front end of the rotary base 3, so that not only a large amount of kinetic energy (similar to a laborious lever) is consumed in the pushing action, but also the end of the rotary base 3 lacks support and is liable to fall down together with the second clamping roller 4, resulting in relatively poor stability of the whole. Therefore, the present design selects to align the spherical protrusion 5021 of the piston head 502 at the middle rear end position of the rotary base 3 and to move the installation position of the piston cylinder 501 backward appropriately to optimize the problem (as shown in fig. 4).

An air passage 1021 is further formed inside the lower splicing member 102, an outlet of the air passage 1021 is communicated with the inside of the piston cylinder 501, and an inlet of the air passage 1021 is connected with a ventilation device through an external pipeline (the pipeline and the ventilation device are not shown in the figure).

In addition, considering that the height that the piston head 502 can push is relatively limited, which may cause the second clamping roller 4 not to be well matched with the first clamping roller 2, in the present embodiment, the end of the rotary base 3 is further provided with a raised boss 302, which makes the overall shape of the rotary base 3 similar to an L shape, the clamping roller mounting seat 6 of the rotary base 3 is arranged on the raised boss 302, and the raised boss 302 is used for reducing the distance between the first clamping roller 2 and the second clamping roller 4 to ensure that the two can be matched with each other.

In addition, a return spring 7 is disposed on the back of the piston cylinder 501, and the end of the return spring 7 is connected to the rotary base 3. When the piston cylinder 501 is inflated with air to make the rotary base 3 rotate upwards, the return spring 7 is in a stretching state; when the air in the piston cylinder 501 is exhausted outwards, the return spring 7 will pull back the rotary base 3 to assist the return.

Furthermore, the piston cylinder 501 and the rotary base 3 are both provided with a blind hole, and the two ends of the return spring 7 are respectively hooked on the two blind holes.

The usage of the design is roughly as follows: install the left and right sides of frame respectively with the form that the symmetry set up (the mounting means is the same basically with prior art, all need make the mounting height of first grip roll just can laminate mutually with the film) with the film centre gripping subassembly of this design earlier. After the film is drawn to pass through the gap between the two clamping rollers, air is introduced into the piston cylinder through the air introducing device, so that the piston head pushes the rotary base upwards until the two clamping rollers are mutually abutted, and the side edge of the film is clamped (as shown in fig. 7); when the clamping roller is not used, the rotary base station can rotate downwards only by discharging air in the piston cylinder outwards, so that the two clamping rollers are separated from each other.

Certainly, since the rotary base table rotates around the rotating shaft, when the second clamping roller abuts against the first clamping roller, the second clamping roller may not be located just under the first clamping roller as the second clamping roller in the prior art, and a slight position deviation may occur.
