DETAILED DESCRIPTION

[0023] The present invention can be further understood through the specific embodiments given below, but they are not intended to limit the present invention.

[0025] Put the material on the first unwinding shaft, pull out one end of the material, make it pass between the driving roller and the driven roller at one end of the loading platform, and pass between the driving roller and the driven roller at the other end, and then reel it on the first receiving shaft;

[0026] A strip hole 6 is respectively provided at both ends of the upper surface of the loading platform 1, a driving roller 7 is provided below the strip hole 6, and the driving roller 7 is fixedly connected to the output shaft of a servo motor 9, a support frame 10 is provided above the strip hole 6, and a driven roller 8 capable of cooperating with the driving roller 7 is provided between the support frame 10 and the strip hole 6, and an adjustment mechanism is provided between the support frame 10 and the driven roller 8 to drive the driven roller 8 to contact or separate with the driving roller 7;

[0027] During the forward movement of the material, the servo motor near the first receiving shaft is controlled to start and drive the active roller at this end to rotate, and the adjustment mechanism at this end enables the active roller and the driven roller to clamp the material, while the adjustment mechanism near the first unwinding shaft separates the active roller and the driven roller, thereby driving the material to move forward;

[0028] When the material needs to be moved backward, the servo motor close to the first unloading shaft is controlled to start and drive the active roller at this end to rotate, and the adjustment mechanism at this end causes the active roller and the driven roller to clamp the material, while the active roller and the driven roller of the adjustment mechanism close to the first receiving shaft are separated, thereby driving the material to move backward.

[0029] The above-mentioned adjustment mechanism includes: a mounting frame 11, a telescopic mechanism arranged between the mounting frame 11 and the support frame 10, and the above-mentioned driven roller 8 is rotatably installed inside the above-mentioned mounting frame 11; the above-mentioned telescopic mechanism is a cylinder, and the movable end of the cylinder 12 is fixedly connected to the mounting frame 11, and the mounting frame is moved downward by controlling the movable end of the cylinder to extend, so that the driven roller and the active roller are squeezed and contacted, and the material between the driven roller and the active roller is clamped.

[0030] The above-mentioned first unwinding shaft 2 is arranged on the output shaft of the first motor 4; the above-mentioned first material receiving shaft 3 is arranged on the output shaft of the second motor 5. The first motor controls the rotation of the first unwinding shaft and the second motor controls the rotation of the first material receiving shaft to avoid the material between the first unwinding shaft and the active roller and between the first material receiving shaft and the active roller from being too long or too short, and the material is started in time to be automatically wound and unwound; the above-mentioned first motor 4 and the second motor 5 are both forward and reverse motors.

[0031] The support frame 10 is in a C-shape.

[0032] The mounting frame 11 is in a C-shape.

[0033] Embodiment 2: A transfer film carrying platform, comprising: a carrying platform 1, wherein one end of the carrying platform 1 is provided with a first unwinding shaft 2, and the other end of the carrying platform 1 is provided with a first receiving shaft 3;

[0034] A strip hole 6 is respectively provided at both ends of the upper surface of the loading platform 1, a driving roller 7 is provided below the strip hole 6, and the driving roller 7 is fixedly connected to the output shaft of a servo motor 9, a support frame 10 is provided above the strip hole 6, and a driven roller 8 capable of cooperating with the driving roller 7 is provided between the support frame 10 and the strip hole 6, and an adjustment mechanism is provided between the support frame 10 and the driven roller 8 to drive the driven roller 8 to contact or separate with the driving roller 7;

[0035] By opening strip holes at both ends of the loading platform and clamping the material through the active roller and the driven roller, the servo motor controls the rotation of the active roller to drive the material forward or backward, thus avoiding the situation where the material advances and retreats at different distances, ensuring the consistency of the material movement distance, thereby improving the accuracy of material transmission and facilitating the improvement of detection accuracy.

[0036] The adjustment mechanism comprises: a mounting frame 11 , and a telescopic mechanism disposed between the mounting frame 11 and the supporting frame 10 , and the driven roller 8 is rotatably mounted inside the mounting frame 11 .

[0037] The telescopic mechanism comprises: a fixed block 14 mounted on the top of the support frame 10, a connecting rod 13, and a rotating mechanism 15 rotatably mounted on the fixed block 14. One end of the connecting rod 13 can penetrate the fixed block 14 and the support frame 10 and be fixedly connected to the mounting frame 11, and the other end located above the fixed block 14 is rotatably connected to the rotating mechanism 15 to drive the connecting rod 13 to move up and down.

[0038] When the active roller needs to contact the driven roller, the handle is held to rotate the first rotating frame around the fixed block, so that the first rotating frame is in a horizontal state and loses its limit in the vertical direction. At this time, the second rotating frame can rotate around the shaft body, so that the end connected to the connecting rod can move up and down. Under the action of gravity, the driven roller contacts the active roller, thereby clamping the material;

[0039] When the active roller needs to be separated from the driven roller, the handle is held to rotate the first rotating frame around the fixed block, so that the first rotating frame is in a vertical state, and the second rotating frame is driven to move upward during the rotation, thereby lifting the mounting frame, and the driven roller is separated from the active roller. When the first rotating frame is in a vertical state, the second rotating frame is rotatably connected to the shaft, and no matter whether the handle is pushed to move upward or downward, the end of the second rotating frame connected to the connecting rod will move upward, thereby ensuring the separation state of the driven roller and the active roller.

[0040] The above-mentioned rotating mechanism 15 includes: a first rotating frame 151 rotatably installed on the fixed block 14, and a second rotating frame 152 arranged inside the first rotating frame 151. The first rotating frame 151 is rotatably installed with a shaft 153 at one end away from the fixed block 14, and the second rotating frame 152 is rotatably sleeved on the circumferential outer wall of this shaft 153, and one end of the second rotating frame 152 is rotatably connected to the end of the connecting rod 13, and the other end is fixedly connected with a handle 154.

[0041] The first unloading shaft 2 is arranged on the output shaft of the first motor 4 .

[0042] The first material receiving shaft 3 is disposed on the output shaft of the second motor 5 .

[0043] The second rotating frame 152 is in an L-shape.

[0044] A limiting plate 155 is disposed on one side of the first rotating frame 151 .

[0045] The working principle is:

[0046] Put the material on the first unwinding shaft, pull out one end of the material, make it pass between the driving roller and the driven roller at one end of the loading platform, and pass between the driving roller and the driven roller at the other end, and then reel it on the first receiving shaft;

[0047] During the forward movement of the material, the servo motor near the first receiving shaft is controlled to start and drive the active roller at this end to rotate, and the adjustment mechanism at this end enables the active roller and the driven roller to clamp the material, while the adjustment mechanism near the first unwinding shaft separates the active roller and the driven roller, thereby driving the material to move forward;

[0048] When the material needs to be moved backward, the servo motor near the first unloading shaft is controlled to start and drive the active roller at this end to rotate, and the adjustment mechanism at this end causes the active roller and the driven roller to clamp the material, while the active roller and the driven roller of the adjustment mechanism near the first receiving shaft are separated, thereby driving the material to move backward;

[0049] When the active roller needs to contact the driven roller, the handle is held to rotate the first rotating frame around the fixed block, so that the first rotating frame is in a horizontal state and loses its limit in the vertical direction. At this time, the second rotating frame can rotate around the shaft body, so that the end connected to the connecting rod can move up and down. Under the action of gravity, the driven roller contacts the active roller, thereby clamping the material;

[0050] When the active roller needs to be separated from the driven roller, the handle is held to rotate the first rotating frame around the fixed block, so that the first rotating frame is in a vertical state, and the second rotating frame is driven to move upward during the rotation, thereby lifting the mounting frame, and the driven roller is separated from the active roller. When the first rotating frame is in a vertical state, the second rotating frame is rotatably connected to the shaft, and no matter whether the handle is pushed to move upward or downward, the end of the second rotating frame connected to the connecting rod will move upward, thereby ensuring the separation state of the driven roller and the active roller.

[0051] When the above-mentioned transfer film carrying platform is used, the material is clamped by the active roller and the driven roller, and the servo motor controls the rotation of the active roller to drive the material forward or backward, thereby avoiding the situation where the material advances and retreats at different distances, ensuring the consistency of the material movement distance, thereby improving the accuracy of material transmission, and facilitating improving the detection accuracy.

[0052] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
