[0002] A baking pan is a dish used to bake food, usually made of metal, with a certain depth and a large surface area.

[0003] After the baking trays are made, they need to be stacked and then manually placed on a conveyor belt to be transported to the next process, which is time-consuming and laborious. Therefore, it is necessary to improve it. Summary of the invention

[0004] The utility model aims to provide an automatic material pushing mechanism for a lower oven trolley machine, which solves the problem of time-consuming and labor-intensive manual material pushing.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a pushing mechanism of an automatic lower oven trolley machine, including a stacking rack, a tray being slidably connected to the inner side of the stacking rack, an adjusting seat and a supporting seat being fixedly connected to the bottom of the stacking rack, a forward and reverse motor being fixedly installed at the front end of the adjusting seat, an output shaft of the forward and reverse motor passing through the adjusting seat and being connected to the adjusting seat by a bearing, an end of the output shaft being fixedly connected to a threaded shaft, and the other end of the threaded shaft being connected to the adjusting seat by a bearing, a moving block being threadedly connected to the outer side of the shaft body of the threaded shaft, and the moving block being slidably connected to the inner side of the adjusting seat, a linkage block being fixedly connected to the side of the moving block away from the adjusting seat, a push plate being hinged on the upper end of the linkage block, the push plate being in contact with the tray, the push plate being slidably connected to the stacking rack, and a retraction mechanism being arranged on the right side of the linkage block.

[0006] The principle of the utility model is that when in use, the pallets are first pre-stacked in the stacking rack, and then the whole is placed on the conveyor belt, and the slope protection is located above the end of the conveyor belt, and then the forward and reverse motors are started, and the forward and reverse motors drive the threaded shaft to rotate, and the threaded shaft drives the moving block to move through the threaded movement, so that the linkage block on the moving block will drive the push plate to move at the same time, and then the push plate can be used to push the pallets stacked in the stacking rack to unload the materials, which is more efficient than manual unloading. Subsequently, the forward and reverse motors are flipped, so that the moving block is reset, and the push plate is flipped by the reaction force from the next pallet, and the ejector pin is squeezed, and when the push plate is reset, the spring will apply the elastic force back to the push plate, so that it remains in a vertical state again, and then the next pallet can be unloaded, and the continuity is high.

[0007] The beneficial effect of the utility model is that an adjustment seat is arranged at the bottom of the stacking rack, a threaded shaft driven by a forward and reverse motor is arranged on the adjustment seat, and the moving block moves by the relative threaded movement between the moving block and the threaded shaft. At the same time, the linkage block on the moving block will also drive the push plate to move, and then the push plate can be used to push out the pallets stacked in the stacking rack for unloading, which is more efficient than manual unloading.

[0008] By setting a retraction mechanism on the right side of the linkage block, the retraction mechanism includes components such as a ramp block, a support plate, a push pin, a limit block, a retaining ring and a spring. During the resetting process of the push plate, the retraction mechanism can be used to elastically support the push plate, thereby not affecting the unloading of the next pallet and achieving higher continuity.

[0009] Furthermore, the left side of the linkage block is fixedly connected with a limiting frame, and the limiting frame is in contact with the push plate. The setting of the limiting frame has a limiting effect on the push plate.

[0010] Further, two slope guards are fixedly connected to the lower right side of the stacking rack, and the two slope guards are in contact with the adjustment seat and the support seat respectively. The arrangement of the slope guards can guide the tray to slide out of the stacking rack.

[0011] Furthermore, the retraction mechanism includes an inclined block fixedly connected to the push plate, a support plate fixedly connected to the right side of the linkage block, a push pin slidably connected inside the support plate, the push pin abuts against the inclined block, a retaining ring fixedly connected to the middle section of the push pin, and a spring sleeved outside the pin body of the push pin. The retraction mechanism is provided to facilitate the flipping of the push plate when it is reset.

[0012] Furthermore, one end of the ejector pin away from the inclined plane block is fixedly connected to a limiting block, and the limiting block is in contact with the support plate. The setting of the limiting block has a limiting effect on the ejector pin.

[0013] Further, one end of the spring is fixedly connected to the retaining ring, and the other end of the spring is fixedly connected to the support plate. Through the setting of the spring, the elastic force can be applied to the ejector pin through the retaining ring.

[0014] Furthermore, a corrugated sleeve is fixedly connected between the retaining ring and the support plate, and the corrugated sleeve is made of rubber material. The arrangement of the corrugated sleeve has a protective effect on the spring. BRIEF DESCRIPTION OF THE DRAWINGS
