Description

Technical Field

[0001] The utility model belongs to the technical field of refrigerator drawer production, and particularly relates to a refrigerator drawer flipping device. Background Art

[0002] At present, refrigerator drawers are usually formed by injection molding into a mold. Subsequently, the flash on the formed refrigerator drawers needs to be removed. The flash removal methods include manual removal and removal by a flash removal device. For example, a plastic product flash removal device provided by the utility model patent with the publication number CN216179209U can automatically remove the flash of the refrigerator drawer. However, this method may result in incomplete flash removal. Subsequently, it is necessary to manually check by eye whether it is completely removed. When manually checking, the refrigerator drawer needs to be flipped to check all parts, which is labor-consuming and needs to be further improved. Content of the Utility Model

[0003] In order to solve the above-mentioned defects of the prior art, the present application provides a refrigerator drawer flipping device, which can flip a refrigerator drawer 180 degrees from above one conveyor belt to above another conveyor belt, facilitating the detection of different areas of the refrigerator drawer without manual flipping.

[0004] In order to achieve the above purpose, the present utility model adopts the following technologies:

Detailed Embodiment

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will describe the embodiments of the present utility model in detail with reference to the drawings. However, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] The embodiment of the present application provides a refrigerator drawer flipping device, as shown in Figures 1 - 3As shown, it includes a support plate 1, a rotating shaft 3, a turning mechanism, a pushing mechanism, etc.

[0023] Specifically, the support plates 1 are a pair, both of which are slidably connected to a slide bar 2, and the pair of support plates 1 are connected to a pushing mechanism, which can simultaneously drive the pair of support plates 1 to move synchronously and oppositely along the slide bar 2, so that the pair of support plates 1 abut against the opposite sides of the refrigerator drawer 7 from the inside of the refrigerator drawer 7; the rotating shaft 3 is rotatably connected between a pair of support seats 301, the rotating shaft 3 is arranged parallel to the support plates 1, and the rotating shaft 3 is connected to one end of the slide bar 2, the axis of the rotating shaft 3 is perpendicular to the length direction of the slide bar 2, and the flipping mechanism is connected to the rotating shaft 3, which is used to drive the slide bar 2 to rotate through the rotating shaft 3.

[0024] For actual use, refer to Figure 1 ,like Figure 1 As shown, a pair of support plates 1 are rotated to the first conveying mechanism 8 for conveying the refrigerator drawer 7 by the rotating mechanism, and the pair of support plates 1 are driven to retract synchronously inward by the pushing mechanism. When the refrigerator drawer 7 is placed on the first conveying mechanism 8, the opening of the refrigerator drawer 7 is directed toward the pair of support plates 1. When the refrigerator drawer 7 moves to the abutment slide bar 2 with the first conveying mechanism 8, the pair of support plates 1 will be in the refrigerator drawer 7. At this time, the pushing mechanism is controlled to drive the pair of support plates 1 to be pushed out synchronously outward so as to abut against the inner wall of the refrigerator drawer 7. Then the flipping mechanism is controlled to drive the slide bar 2 to rotate upward 180 degrees through the rotating shaft 3. Because the support plates 1 and the inner walls of the refrigerator drawer 7 have friction, the refrigerator drawer 7 will be driven to flip 180 degrees synchronously. A second conveying mechanism opposite to the conveying direction of the first conveying mechanism 8 is set at the position reached after the refrigerator drawer 7 is flipped 180 degrees, so that the pushing mechanism drives the pair of support plates 1 to move inward, and the second conveying mechanism can drive the flipped refrigerator drawer 7 to separate from the support plates 1 to inspect another part of the refrigerator drawer 7.

[0025] For details, see Figure 2 The pushing mechanism includes a screw rod 4 and a driving motor 401. The two ends of the screw rod 4 have threads with opposite rotation directions, and are respectively threadedly connected to a pair of support plates 1. The output shaft of the driving motor 401 is connected to one end of the screw rod 4, and the driving motor 401 is fixed to the rotating shaft 3. Only one power source, the driving motor 401, is required to drive the screw rod 4 to rotate, so as to drive a pair of support plates 1 to move synchronously inward / outward in opposite directions. Compared with realizing the synchronous reverse movement of a pair of support plates 1 by two electric push cylinders, the synchronization is stronger and the structure is simpler. More specifically, the rotating shaft 3 can be set to pass through a rectangular block 302 and be fixedly connected to the rectangular block 302. It is connected to the driving motor 401 and one end of the sliding rod 2 through one side of the rectangular block 302, so as to facilitate the fixing of the driving motor 401 and the sliding rod 2.

[0026] For details, see Figure 3, the flipping mechanism includes a rack 501, a slide rail 504, and a cylinder 5. A gear ring 502 is sleeved on the rotating shaft 3. The rack 501 is meshed and connected below the gear ring 502, and the rack 501 is connected to the telescopic end of the cylinder 5. The telescopic direction of the telescopic end of the cylinder 5 is parallel to the length direction of the rack 501. When the telescopic end of the cylinder 5 drives the rack 501 to push out, it can drive the gear ring 502 to rotate, and then drive the rotating shaft 3 and the slide bar 2 to rotate to complete the flipping. More specifically, there are a pair of gear rings 502, both sleeved on the rotating shaft 3, and the pair of gear rings 502 are respectively at both ends of the rectangular block 302. There are also a pair of racks 501, which are respectively meshed and connected to the pair of gear rings 502, and a sliding sleeve 503 is arranged between the pair of racks 501. The sliding sleeve 503 is slidably connected to a slide rail 504. The length direction of the slide rail 504 is parallel to the length direction of the rack 501. The telescopic end of the cylinder 5 is connected to the two racks 501 through a cross plate 505. In this way, the two ends of the rotating shaft 3 can be stressed to complete the rotation, improving the stability during the rotation process. And the rack 501 slides on the slide rail 504 through the sliding sleeve 503, which can improve the stability during the movement of the rack 501.

[0027] Preferably, referring to Figure 1 , Figure 2 , a baffle 6 is provided at the top of each of the support plates 1. The length direction of the baffle 6 is parallel to the axial direction of the slide bar 2. The outer end of the baffle 6 protruding outwards from the support plate 1. When the bottom of the side with an opening of the refrigerator drawer 7 abuts against the slide bar 2, the side with an opening of the refrigerator drawer 7 abuts against the baffle 6, which can prevent the situation that when the refrigerator drawer 7 only abuts against the slide bar 2, the first conveying mechanism 8 continues to drive the refrigerator drawer 7 to move, resulting in the tipping of the refrigerator drawer 7.

[0028] The above are only some embodiments listed in this application and do not limit this application.
