Detailed Implementation
[0018] 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.
[0019] Please see Figs. 1-3 This utility model provides an embodiment of a straightening device for a corrugated evaporator tube, comprising a material feeding support mechanism 1 and a size adjustment mechanism 2. The size adjustment mechanism 2 is disposed on the material feeding support mechanism 1. The material feeding support mechanism 1 includes a support frame 3. Limiting rods 4 are symmetrically fixedly connected to the inner side of the support frame 3. A threaded plate 5 is fixedly installed at the top of the support frame 3. A first concave roller 6 is uniformly rotatably installed on the inner side of the support frame 3. A second concave roller 7 is provided at the end of the inner side of the support frame 3 away from the first concave roller 6. Limiting grooves 8 are respectively opened on both sides of the end of the support frame 3 near the second concave roller 7. A sliding connector 10 is slidably connected to the inner side of the limiting groove 8. An energy storage spring 9 is fixedly installed at the bottom end of the sliding connector 10.
[0020] The size adjustment mechanism 2 includes a lifting bracket 14. A limiting slide plate 15 is symmetrically fixedly connected to the outer side of the lifting bracket 14. A third concave roller 16 is uniformly rotatably installed on the inner side of the lifting bracket 14. A top bracket 17 is fixedly connected to the top of the lifting bracket 14. A threaded rod 18 is rotatably connected to the middle of the top of the top of the top bracket 17. A knob 19 is fixedly installed at the top of the threaded rod 18.
[0021] Two limiting rods 4 are symmetrically arranged on the same side inside the support frame 3. Two limiting slide plates 15 are arranged on the same side outside the lifting bracket 14. The inner sides of the two limiting slide plates 15 are slidably connected to the outer sides of the two limiting rods 4. The two limiting rods 4 limit the two limiting slide plates 15, thereby ensuring the vertical lifting of the lifting bracket 14. The threaded rod 18 is threadedly connected to the middle of the threaded plate 5. The lifting of the threaded rod 18 can be adjusted by rotating the knob 19 to drive the threaded rod 18 to rotate. The lifting of the threaded rod 18 drives the lifting bracket 14 to lift, thereby adjusting the position of the third concave roller 16 to adapt to corrugated evaporator tubes of different diameters.
[0022] The first concave roller 6 and the second concave roller 7 are evenly distributed. The third concave roller 16, located in the middle of the lifting bracket 14, is located directly above the first concave roller 6 in the middle of the support frame 3. A rotating wheel 12 is fixedly installed at one end of the first concave roller 6 in the middle of the support frame 3. A crank 13 is fixedly installed on the outer side of the rotating wheel 12 away from the support frame 3. The first concave roller 6 can be rotated by rotating the rotating wheel 12 through the crank 13, thereby pushing the corrugated evaporator tube located between the first concave roller 6 and the third concave roller 16 to move. A support base 11 is fixedly installed at the bottom of the support frame 3. The support base 11 can be placed on the ground for straightening operations. At the same time, the support base 11 can be stepped on by foot during the straightening process to strengthen the fixation of the material conveying support mechanism 1.
[0023] The bottom end of the energy storage spring 9 is fixedly installed on the inner bottom end of the limiting slide groove 8. The two ends of the second concave roller 7 are respectively rotatably connected to the sliding connector 10. The end of the support frame 3 near the second concave roller 7 is the input end. The corrugated evaporator tube enters the interior of the support frame 3 through the top of the second concave roller 7. The second concave roller 7 floats up and down through the elastic connection of the energy storage spring 9, thereby adapting to the corrugated evaporator tube with different degrees of curvature and avoiding the rigid connection of the roller from exerting too much pressure on the corrugated evaporator tube, thereby breaking the corrugated evaporator tube.
[0024] Working Principle: During use, the corrugated evaporator tube is first inserted into the support frame 3 by external force, with one end near the second concave roller 7. The tube is then inserted until the end of the corrugated evaporator tube is connected to the top of the first concave roller 6 located at the end of the support frame 3 furthest from the second concave roller 7. Then, the position of the size adjustment mechanism 2 is adjusted according to the outer diameter of the corrugated evaporator tube. The knob 19 is turned downwards by external force. The rotation of the knob 19 drives the threaded rod 18 to rotate. Since the threaded rod 18 is threadedly connected to the threaded plate 5, the rotation of the threaded rod 18 pushes the top support 17 downwards. The movement of the top support 17, along with the lifting support 14, drives the third concave roller 16 downwards until the bottom of the third concave roller 16, located in the middle, is tightly against the top of the corrugated evaporator tube, and the bottom of the corrugated evaporator tube is also tightly against the top. At the top of the first concave roller 6 in the middle of the support frame 3, the handle 13 is turned by external force to drive the rotating wheel 12 to rotate. The rotation of the rotating wheel 12 drives the first concave roller 6 in the middle of the support frame 3 to rotate. Under the action of friction, the rotation of the first concave roller 6 pushes the corrugated evaporator tube to move away from the second concave roller 7. The corrugated evaporator tube is straightened by the compression of the first concave roller 6 and the third concave roller 16. The corrugated evaporator tube enters the interior of the support frame 3 from the top of the second concave roller 7. When the downwardly bent part of the corrugated evaporator tube moves to the top of the second concave roller 7, the corrugated evaporator tube presses the second concave roller 7 downward. The second concave roller 7 is compressed, which drives the sliding connector 10 to move downward and compresses the energy storage spring 9 to contract, thereby gently conveying the corrugated evaporator tube into the interior of the support frame 3 for straightening.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
