Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refrigerator top cover processing, in particular to a conveying buffer device for refrigerator injection molding top cover. Background Art
[0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is also a civilian product that keeps food or other items in a constant low temperature and cold state. The box contains a compressor, an ice maker, a cabinet or box for freezing, and a storage box with a refrigeration device. The injection-molded top cover of the refrigerator is made by stamping.
[0003] In the process of conveying the injection molded top cover to other workstations, it is usually first transported horizontally by a conveyor belt, and then automatically slides to the destination through a guide track. When the injection molded top cover slides down to the bottom landing point, it has a certain impact force, which can easily cause the injection molded top cover to collide and be damaged. In addition, the common conveying device cannot flexibly change the horizontal orientation of the conveyance and cannot directly convey it to the right place, resulting in poor practical applicability and inconvenience in the processing of the injection molded top cover. Therefore, it is necessary to propose a conveying buffer device for the refrigerator injection molded top cover to solve this problem. Utility Model Content

[0006] By adopting the above technical scheme, the injection molded top cover is sent to the right side by the conveyor belt into the discharge bin, and the injection molded top cover slides down due to the inclined setting of the discharge bin. When it reaches the landing point, the impact force it generates hits the buffer plate, and the sliding frame drives the push plate to slide on the outside of the four cross bars, compressing the spring. The rebound buffer generated by it reduces the damage of the injection molded top cover during collision, making the transportation of the injection molded top cover safer.
[0007] The utility model is further configured as follows: a plurality of discharge rollers are axially arranged in the discharge bin, and the plurality of discharge rollers are equidistantly distributed, and the cross-section of the discharge bin gradually decreases from the upper port to the lower port, and reaches a minimum value when reaching the buffer plate.
[0008] By adopting the above technical solution, the injection molded top cover can be stably transported in the discharge bin through the support of the discharge roller. At the same time, as the cross-section of the discharge bin channel gradually decreases, the injection molded top cover can accurately reach a fixed landing position to avoid falling and damage.
[0009] The utility model is further configured as follows: two pulleys that fit the inner bottom wall of the buffer frame are installed at the bottom of the push plate, and four universal wheels that fit closely to the ground are installed at the bottom of the buffer frame.

[0011] The utility model is further configured as follows: a rubber buffer pad is arranged on the left side of the buffer plate, and an opening for horizontal movement of the sliding frame is arranged on the right side of the buffer frame.
[0012] By adopting the above technical solution, the rubber buffer pad can be further prevented from being damaged when it touches the injection molded top cover, and the setting of the opening enables the sliding frame to smoothly drive the push plate to slide left and right.
[0013] The utility model is further configured as follows: the steering mechanism includes a fixed plate installed inside the second bracket and located directly below the horizontal end of the discharge bin, a motor and a rotating shaft are installed on the upper end surface of the fixed plate, two ends of the rotating shaft are respectively rotatably connected to the fixed plate and the conveying bin through bearings, and are fixedly connected to the discharge bin, a main gear is installed at the output end of the motor, and a slave gear meshing with the main gear is installed on the outer side of the rotating shaft.
[0014] By adopting the above technical solution, the main gear is driven to rotate by the motor, and the meshing drives the slave gear to rotate, so that the rotating shaft rotates, thereby flexibly adjusting the horizontal position of the discharge bin.
[0015] The beneficial effects of the utility model are:
