[0002] With the development of science and technology, more and more metal products are manufactured, and most of them cannot avoid being corroded by water and rusting, which leads to the development of more and more anti-rust methods, and hot-dip galvanizing is one of them. An important item in hot-dip tinning is to dry the metal parts to be tinned, so that the moisture of the metal parts can be fully dried, and the parts can be preheated in advance to prevent the subsequent hot-dip galvanizing from causing the zinc solution to burst and splash and cause safety accidents. After the existing dryer is stopped, the internal high temperature cannot be completely dissipated, which makes it inconvenient to load and unload the dried parts. In addition, when drying small metal parts, it is very time-consuming and laborious to stack the parts baskets, which greatly wastes time and energy. Utility Model Content

[0003] The utility model aims to provide a chain-type feeding device for a hot-dip galvanizing unit drying furnace, so as to solve the problem in the background technology that it is time-consuming and laborious to stack the parts baskets for drying small parts.

[0005] Preferably, the chain transmission mechanism includes: a transverse rotating shaft, which is fixedly mounted on the output end of the hydraulic push cylinder, and sprockets are rotatably mounted on both ends of the transverse rotating shaft, a slide is fixedly mounted on the outer surface of the base frame, and a lifting platform is slidably mounted inside the slide, and the lifting platform is concave in shape, a bolt is threadedly mounted on the outer surface of one end of the base frame close to the hydraulic push cylinder, and a transmission chain is arranged between the bolt and the base frame, and the gap at one end of the transmission chain is passed through by the bolt, the bolt is threadedly mounted on the outer surface of the lifting platform, and a bolt is arranged between the lifting platform and the transmission chain, and the transmission chain is meshed with the sprocket.

[0006] By adopting the above technical solution, the parts basket can be pushed into the positioning frame after weighing is completed, and the horizontal rotating shaft is pushed by the hydraulic push cylinder, so that the sprocket rotates with the transmission chain as the fulcrum as it is pushed out, and the lifting platform is pulled up, so that the parts basket is slowly raised for stacking, which is convenient for subsequent entry into the drying furnace for drying.

[0007] Preferably, a sliding track is fixedly installed on the side surface of one end of the base frame close to the lifting platform, and a push-activated trigger switch is fixedly installed on the end of the sliding track away from the horizontal rotation axis, an electric slider is slidably installed on the outer surface of the sliding track, and a supporting top cylinder is fixedly installed on the outer surface of the electric slider away from the base frame, a supporting plate is fixedly installed on the outer surface of the supporting top cylinder, and inclined protrusions are provided at both ends of the supporting plate, and the outer surface of the supporting plate does not fit the outer surface of the lifting platform.

[0008] By adopting the above technical solution, the supporting plate can be driven by the electric slider to enter the interior of the positioning frame, and the supporting plate can be lifted up by the supporting cylinder to lift the parts basket. The parts basket can be automatically aligned by the inclined protrusions at both ends of the supporting plate, and then the parts basket containing the material can be sent into the drying box through the sliding track.

[0009] Preferably, one-way plates are rotatably mounted on the inner surfaces of both sides of the positioning frame, and a torsion spring is arranged between the one-way plate and the positioning frame, one end of the torsion spring is fixed inside the one-way plate, and the other end of the torsion spring is fixed to the outer surface of the positioning frame.

[0010] By adopting the above technical solution, the hydraulic push cylinder will cause the lifting platform to push up the parts basket, and the parts basket will squeeze the one-way plate to allow the parts basket to pass. Then the torsion spring will push the one-way plate back, the lifting platform will fall, and the parts basket will be dragged by the one-way plate, making it convenient for the next weighed parts basket to enter and be stacked.

[0011] Preferably, a sliding mechanism is provided between the base frame and the positioning frame, and the parts basket can be sent out from the positioning frame through the sliding mechanism.

[0012] By adopting the above technical solution, the neatly stacked parts baskets can be taken out from the middle of the positioning frame by the taking tray.

[0016] By adopting the above technical solution, when the parts basket is transported out of the positioning frame, it can be guided by the inclined surface of the sliding support rail. After the parts basket is sent into the drying furnace, the supporting plate can be lowered so that the parts basket can be supported by the sliding support rail and stay in the drying furnace. When the drying is completed, the parts basket can be lifted up again and placed on the shorter sliding support rail, which is convenient for the subsequent use of tools to remove all the parts baskets.

[0018] 1. The approximate number of parts in the parts basket can be controlled by weighing on the weighing platform. Then the weighed parts basket is pushed into the positioning frame. The hydraulic push cylinder is started to push the horizontal rotation shaft upward, driving the sprocket to move upward and engage to pull the transmission chain, so that the lifting platform moves up along the slideway, so that the parts basket pushes the one-way plate to pass through, and then the thrust of the torsion spring is used to reset the one-way plate, so that the parts basket is lifted up for stacking, which improves the stacking efficiency;

[0019] 2. When the parts baskets are stacked to a certain number, the sensor of the positioning rack will be triggered. At this time, the electric slide will enter the bottom of the positioning rack, lift the support plate through the support cylinder, and then push the sliding block out through the electric push rod, so that the sliding block moves along the direction of the sliding support block. At the same time, the sliding support block keeps the height of the two one-way plates consistent, so that the parts baskets can be neatly stacked inside the positioning rack and remain stable, so that the neatly stacked parts baskets can be taken out from the positioning rack and sent to the drying furnace;

[0020] 3. As the electric slider follows the sliding track and enters the bottom of the positioning frame, the supporting top cylinder will lift the supporting plate, so that the supporting plate will lift the parts basket. Then the sliding block will open, and the stacked parts basket will be moved out and sent into the drying oven through the smooth movement of the electric slider. Then the supporting top cylinder will shrink, and the parts basket will fall on the sliding support track, and the electric slider will move out of the drying oven. When the drying is completed, the electric slider will enter the drying oven to take out the parts basket and place it on a shorter sliding support track. After that, the stacked parts basket can be transported away as a whole by forklifts and other tools for the next processing step. BRIEF DESCRIPTION OF THE DRAWINGS
