DETAILED DESCRIPTION

[0019] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0020] See also Figure 1-3 As shown, the present embodiment provides an edge alignment mechanism for a rear cover plate of a refrigerator, comprising a base 1, two mutually parallel slide rails 2 are fixedly installed on the top of the base 1, a moving plate 3 is slidably installed on the two slide rails 2 at the same time, a screw rod 4 is threadedly connected to the bottom of the moving plate 3, two ends of the screw rod 4 are respectively rotatably connected to the two sides of the base 1, a driving motor for driving the screw rod 4 to rotate is installed on the base 1, a support frame 5 is fixedly installed on the top of the moving plate 3, a slide frame 6 is slidably installed on the top of the support frame 5, clamping plates 7 are fixedly installed on both sides of the bottom of the slide frame 6, anti-skid pads 8 are fixedly installed on the bottom of the two clamping plates 7, a plurality of anti-skid pads 9 distributed at equal distances are fixedly installed on the top of the moving plate 3, a screw rod 10 is threadedly connected to the slide frame 6, the bottom end of the screw rod 10 is rotatably connected to the top of the support frame 5, a knob 11 is fixedly installed on the top of the screw rod 10, and the knob 11 is used to facilitate the rotation of the screw rod 10;

[0021] When the screw rod 14 is rotated in the clockwise direction, the screw rod 14 will drive the moving plate 3 to move laterally along the two slide rails 2 toward the rear side of the base 1, and the screw rod will move laterally toward the front side of the base 1. When the screw rod 210 is rotated in the clockwise direction, the screw rod 210 will drive the two clamping plates 7 to move downward at the same time through the slide 16 to reduce the distance between the clamping plates 7 and the moving plate 3, and increase the distance between the clamping plates 7 and the moving plate 3. The distance between the clamping plates 7 and the moving plate 3 is adjusted by the positive and negative rotation of the screw rod 210 to clamp the rear cover plate placed on the top of the moving plate 3. When the clamping plates 7 and the moving plate 3 clamp the rear cover plate, the anti-skid pads 29 and 18 are used to increase the friction between the rear cover plate and the moving plate 3 to prevent the rear cover plate from slipping off.

[0022] A lifting frame 12 is slidably installed on the top of the base 1, and two slides 13 are slidably installed on both sides of the lifting frame 12. A grinding plate 14 is fixedly installed on the opposite sides of the two slides 13. Slide rods 15 are slidably installed on both sides of the top of the lifting frame 12. The bottom ends of the two slide rods 15 are respectively fixedly connected to the tops of the two slides 13. A cylinder 16 is fixedly installed on the top of the lifting frame 12. The output end of the cylinder 16 is rotatably installed with two mutually symmetrical push-pull plates 18 by a fixed block. The ends of the two push-pull plates 18 away from the fixed block are rotatably connected to the outer peripheral walls of the two slide rods 15 respectively.

[0023] When the cylinder 16 pushes the fixed block outward, the fixed block will drive the two slide bars 15 to approach each other through the two push-pull plates 18, otherwise the two slide bars 15 will move away from each other. When the two slide bars 15 approach each other, they will drive the two grinding plates 14 to approach each other through the two slide racks 13, otherwise the two grinding plates 14 will move away from each other. In summary, the distance between the two grinding plates 14 can be adjusted so that it can be changed according to the different sizes of the rear cover plate, thereby improving adaptability.

[0024] A rotating rod 19 is rotatably installed at the bottom of the base 1, and a push-pull plate 20 is fixedly installed at one end of the rotating rod 19 near the lifting frame 12. The rotating rod 19 and the screw rod 14 are driven by a pulley. A slide groove 21 is provided at the bottom of the lifting frame 12 near the push-pull plate 20, and the end of the push-pull plate 20 away from the rotating rod 19 is slidably connected with the slide groove 21.

[0025] When the screw rod 4 rotates, it will drive the rotating rod 19 to rotate synchronously through the pulley, and the rotating rotating rod 19 will drive the lifting frame 12 to reciprocate up and down through the push-pull plate 20. At the same time, the end of the push-pull plate 20 away from the rotating rod 19 will slide in the slide groove 21 to correct the position change between the push-pull plate 20 and the lifting plate.

[0026] When the utility model is in use, the rear cover plate is placed flat on the top of the several anti-skid pads 29 on the top of the moving plate 3, and then the moving plate 3 is moved along the slide rail 2 to between the two grinding plates 14, until the moving plate 3 moves between the two grinding plates 14, and then the distance between the two grinding plates 14 is reduced, so that the two grinding plates 14 clamp the rear cover plate between the two, and then the screw rod 2 10 is rotated clockwise through the knob 11, so that the screw rod 2 10 drives the two clamping plates 7 to squeeze the top of the rear cover plate through the slide 1 6, until the clamping plate 7 clamps the rear cover plate firmly on the top of the moving plate 3, and then the moving plate 3 is moved horizontally on the slide rail 2, so that the two grinding plates 14 respectively grinds the two side edges of the rear cover plate horizontally. During the horizontal movement of the movable plate 3, the lifting frame 12 drives the two grinding plates 14 to reciprocate up and down in the vertical direction through the two slides 13, so that the grinding plates 14 grind the two side edges of the rear cover plate reciprocatingly up and down. By grinding the grinding plates 14 at the same time horizontally and vertically on the edge of the rear cover plate, the efficiency of trimming the rear cover plate is improved. When the trimming of the rear cover plate is completed, the screw rod 2 10 is rotated counterclockwise by the knob 11, so that the screw rod 2 10 drives the two clamping plates 7 to disengage the clamping of the rear cover plate through the slide 1 6, so that the processed rear cover plate can be removed from the movable plate 3.
