DETAILED DESCRIPTION

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 The present invention provides a technical solution as follows:

[0022] Example:

[0023] In this embodiment, an environmentally friendly PVA water transfer film production equipment with a correction structure includes a processing box 1, a PVA film 2, and a limiting shaft 13. The processing box 1 contains a processing device. An operating table 4 and a pair of connecting plates 5 are located on one side of the processing box 1. A material feeding device for the PVA film 2 is located on one side of the operating table 4. The PVA film 2 extends into the processing box 1 through the upper end of the operating table 4. The operating table 4 is located below the connecting plates 5. A crossbar 6 is connected to the pair of connecting plates 5, and a photoelectric sensor 7 is connected to the crossbar 6. The photoelectric sensor 7 is located on one side of the PVA film 2, and baffles 3 are provided on both sides of the operating table 4. A correction roller 9 is provided above the operating table 4. One end of the correction roller 9 is movably mounted on the baffle 3, and the other end of the correction roller 9 is movably mounted on another baffle 3 through a limiting shaft 13. A connecting plate 24 is provided on one side of the correction roller 9, and an inclined block 22 is provided at the lower end of the connecting plate 24. A hydraulic telescopic rod 14 is provided on the baffle 3, and the output end of the hydraulic telescopic rod 14 is connected to the side of the connecting plate 24 away from the correction roller 9.

[0024] Both the tension adjusting roller 8 and the correction roller 9 mentioned above are powered by a rotary motor;

[0025] The processing device inside the processing box 1 is used to process the PVA film 2. This processing device includes several transfer rollers. One end of the PVA film 2 is mounted on the feeding device, and the other end is transferred and processed via several rotating rollers inside the processing box 1. The photoelectric sensor 7 is used to detect positional deviations of the PVA film 2. When the photoelectric sensor 7 detects a positional deviation, it transmits a signal to the controller. The controller controls the forward and reverse activation and extension / retraction of the hydraulic telescopic rod 14 according to the magnitude and direction of the deviation, causing the connecting plate 24 to move in the same direction. This, in turn, causes the alignment roller 9 to move in the same direction horizontally, thus performing alignment operations on the PVA film 2.

[0026] Wherein, the deviation correction roller 9 side and located on the operating platform 4 upper end is equipped with the link seat 11, the link seat 11 upper end is equipped with the connecting bolt 12, the connecting bolt 12 is movably equipped with the link frame 10, the link frame 10 upper end is equipped with the tension adjusting roller 8, and the link frame 10 side is equipped with the link bolt 17, the link bolt 17 is connected with the transmission rod 15, the transmission rod 15 far away from the link bolt 17 one end is equipped with the movable block 18, the movable block 18 is equipped with the sliding slot 21, the sliding slot 21 is movably connected with the inclined block 22, the sliding slot 21 is the inclined rectangular slot, and the sliding slot 21 is matched with the inclined block 22.

[0027] Through the connection of connecting bolt 12 and link frame 10, the link frame 10 can rotate around the connecting bolt 12, when the PVA film 2 deviates, the hydraulic telescopic rod 14 starts, drives the connecting plate 24 to move in the same direction, under the design of sliding slot 21 and inclined block 22, when the PVA film 2 deviates towards the hydraulic telescopic rod 14, the hydraulic telescopic rod 14 starts positively and extends, drives the deviation correction roller 9 to move away from the hydraulic telescopic rod 14, so that the tension of the PVA film 2 near the hydraulic telescopic rod 14 increases, and the tension of the other side of the PVA film 2 decreases, wherein the inclined block 22 is consistent with the moving direction of the deviation correction roller 9, drives the sliding slot 21 to move towards the bottom of the inclined block 22, so that the movable block 18 moves down, under the action of transmission rod 15 and link bolt 17, drives one side of the link frame 10 to move down in the same direction, and the other side of the link frame 10 moves up, so that the tension adjusting roller 8 moves in the same direction, so that the tension of the PVA film 2 near the hydraulic telescopic rod 14 decreases, and the tension of the other side of the PVA film 2 increases, when the deviation direction of the PVA film 2 changes, reverse operation can be performed; in summary, when the PVA film 2 is corrected, the influence of uneven tension distribution on the PVA film 2 can be reduced, so that the processing and output of the PVA film 2 have high quality.

[0028] Wherein, the connecting plate 24 is equipped with the movable hole 23, the deviation correction roller 9 is equipped with the guide shaft 19, the guide shaft 19 is movably arranged in the movable hole 23, and the guide shaft 19 is arranged on a pair of baffle plates 3 at both ends.

[0029] Wherein, the transmission rod 15 is provided with a through hole, the through hole is movably provided with a limiting column 16, and the limiting column 16 is arranged on the upper end of the operating platform 4.

[0030] Through the design of the limiting column 16, the longitudinal movement of the transmission rod 15 can be guided, so that the vertical movement of the transmission rod 15 is more smooth.

[0031] Wherein, the guide shaft 19 is vertically aligned with the deviation correction roller 9, and the guide shaft 19 and the deviation correction roller 9 are arranged in parallel.

[0032] Through the design of the guide shaft 19, the movement of the connecting plate 24 in the horizontal direction can be limited and guided.

[0033] The tension adjusting roller 8 and the deviation correcting roller 9 are located at the same horizontal position and are arranged in parallel with each other.

[0034] When the PVA film 2 does not deviate, the tension adjusting roller 8 does not affect the transmission of the PVA film 2.

[0035] The balance column 20 is movably arranged at the upper end of the operation table 4.

[0036] The balance column 20 is used to balance the connecting frame 10. When the PVA film 2 does not deviate, the tension adjusting roller 8, in combination with the rotating rollers and the deviation correcting roller 9 in the processing box 1, makes the PVA film 2 have a certain tension, so that the PVA film 2 can be normally transmitted and processed on the processing box 1 and the operation table 4.

[0037] Working principle: when the PVA film 2 deviates, the photoelectric sensor 7 detects the deviation of the position of the PVA film 2 and transmits a signal to the controller. The controller controls the hydraulic telescopic rod 14 to start according to the deviation size and direction, and drives the connecting plate 24 to move in the same direction. Under the design of the sliding groove 21 and the inclined block 22, when the PVA film 2 deviates towards the hydraulic telescopic rod 14, the control hydraulic telescopic rod 14 is started and elongated in the positive direction, driving the deviation correcting roller 9 to move away from the direction of the hydraulic telescopic rod 14, so that the tension on the side of the PVA film 2 close to the hydraulic telescopic rod 14 increases, and the tension on the other side of the PVA film 2 decreases. The movement direction of the inclined block 22 is consistent with that of the deviation correcting roller 9, which pushes the sliding groove 21 to move towards the bottom end of the inclined block 22 on the inclined block 22, so that the movable block 18 moves downward. Under the action of the transmission rod 15 and the connecting bolt 17, one side of the connecting frame 10 moves downward in the same direction, and the other side of the connecting frame 10 moves upward, so that the tension adjusting roller 8 moves in the same direction, thereby reducing the tension on one end of the PVA film 2 close to the hydraulic telescopic rod 14 and increasing the tension on the other side of the PVA film 2 away from the hydraulic telescopic rod 14, so that when the PVA film 2 is corrected, the influence of uneven tension distribution on the PVA film 2 is reduced, and the processing and output of the PVA film 2 have high quality. When the deviation direction of the PVA film 2 changes, the reverse operation can be performed.

[0038] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
