A support mechanism is provided on one side of the fixed plates, and a guiding mechanism is provided on one side of the fixed plates. The support mechanism includes a support frame located on one side of the fixed plates. The guiding mechanism includes a guiding frame located on one side of the fixed plates. A driving frame is installed on the fixed plates. The beneficial effect of this utility model is that when lifting the storage basket, the storage basket can be moved above the guiding frame, and then the storage basket is moved downward. The vibration damping pad can damp the storage basket to prevent it from shaking. Then the storage basket can be moved inside the guiding frame, and the storage basket can be accurately dropped into the zinc permeation furnace through the guiding frame, improving the working efficiency, reducing the safety hazard, and preventing the storage basket from colliding with the zinc permeation furnace, which can prevent the zinc permeation furnace from being damaged and extend the service life of the zinc permeation furnace.

During the process of the zincizing raw materials passing through the middle of the feed hopper, by applying high voltage to the contact head, the static electricity of the zincizing raw materials is removed, preventing the zincizing raw materials from adhering to the inside of the feed hopper due to static electricity.

An intercepting structure is arranged inside the sealing sleeve 4. The intercepting structure includes a movable plate 10 slidably connected to the inner top of the sealing sleeve 4. An opening is provided in the middle of the movable plate 10, and the opening inside the movable plate 10 communicates with the inside of the zinc melting furnace 1. A plurality of equally spaced chutes 16 are provided on both sides of the sealing sleeve 4, and a blocking plate 12 is slidably connected between two symmetrically distributed chutes 16. Slide bars 15 are fixedly connected to both sides of the blocking plate 12, and the blocking plate 12 is slidably connected between two symmetrically distributed chutes 16 through the two slide bars 15. Connecting rods 13 are fixedly connected to both sides of the blocking plate 12, and slots are formed at the top and bottom of the blocking plate 12 for the two connecting rods 13. The connecting rod 13 is slidably connected inside the slot of another blocking plate 12, and a plurality of blocking plates 12 form a whole through the mutual sliding between the connecting rods 13, and the whole formed by the plurality of blocking plates 12 has elasticity.

[0029] Limit slots 14 are provided on both sides of the bottom of the movable plate 10, and the inside of the limit slots 14 is slidably connected to the connecting rod 13. Symmetrically distributed fixing plates 11 are fixedly connected to the inner bottom of the sealing sleeve 4, and the top of the fixing plate 11 is slidably connected to the connecting rod 13.

[0030] The limit slots 14 at the bottom of the movable plate 10 are located at the upper end of the whole formed by the plurality of blocking plates 12, and the fixing plates 11 are located at the lower end of the whole formed by the plurality of blocking plates 12.

[0031] Symmetrically distributed fixing blocks 5 are fixedly connected to both ends of the top of the sealing sleeve 4, and two symmetrically distributed lead screws 6 are rotatably connected between the two fixing blocks 5. Symmetrically distributed slide rails are fixedly connected to both sides of the sealing sleeve 4.

[0032] One end of the lead screw 6 penetrates inside the fixed block 5, and a driven wheel 7 is fixedly connected to the end of the lead screw 6 penetrating the fixed block 5. One end of the sealing sleeve 4 is fixedly connected to the driven wheel 7, and a motor 8 is fixedly connected to the other end of the sealing sleeve 4. The output end of the motor 8 is fixedly connected to a rotating wheel 9, and the rotating wheel 9 and the two driven wheels 7 are rotationally connected by a belt.

[0033] The top of the movable plate 10 is fixedly connected to a moving plate 20. Both sides of the top of the moving plate 20 are fixedly connected with two symmetrically distributed threaded sleeves 21, and the inside of the threaded sleeve 21 is threadedly connected to the lead screw 6. Both sides of the bottom of the moving plate 20 are fixedly connected with load-bearing bars 22, and the load-bearing bars 22 are slidably connected to the outer sides of the symmetrically distributed slide rails on both sides of the sealing sleeve 4.

[0034] The top of the moving plate 20 is fixedly connected to a feed hopper 17. The feed hopper 17 is arranged to be narrow in the middle and wide at both ends. The outside of the middle of the feed hopper 17 is fixedly connected to a fixing ring 18, and the inner side of the fixing ring 18 is fixedly connected with a plurality of annularly distributed contact heads 19, and the contact heads 19 extend to the middle inside the feed hopper 17.

[0035] In this powder feeding device for zinc infiltration processing of metal products, the rotation of the lead screw 6 drives the movement of the moving plate 20, so that the moving plate 20 drives the movable plate 10 to slide inside the sealing sleeve 4. During the movement of the movable plate 10, the movable plate 10 drives the blocking plate 12 in contact with it to move along with it through the limiting groove 14 at the bottom. During this process, the connecting rod 13 will slide inside the limiting groove 14. At the same time, the blocking plate 12 will also slide between the two sliding grooves 16 through the sliding strip 15. The mutual contact of the two blocking plates 12 through the connecting rod 13 enables the upper blocking plate 12 to drive the lower blocking plate 12, so that the whole formed by the multiple blocking plates 12 follows the movement of the movable plate 10 inside the sealing sleeve 4, making the whole formed by the blocking plates 12 expand and contract. During the process of adding zinc infiltration raw materials from the feed hopper 17 into the zinc melting furnace 1, the movement of the movable plate 10 drives the feed hopper 17 to move on the top of the sealing sleeve 4, so that the zinc infiltration raw materials can be evenly added into the zinc melting furnace 1. At the same time, during the movement of the movable plate 10, it drives the whole formed by the multiple blocking plates 12 to contract, sealing the opening of the sealing sleeve 4, so that the zinc melting furnace 1 can add zinc infiltration raw materials during operation without affecting the temperature inside the zinc melting furnace 1, ensuring the uniformity and continuity of the zinc infiltration effect;

[0036] The driving wheel 9 is driven to rotate by the motor 8, so that the driving wheel 9 drives two driven wheels 7 to rotate through a belt, and the two driven wheels 7 drive the lead screw 6 to rotate between the two fixed blocks 5. During the rotation of the lead screw 6, the lead screw 6 drives the moving plate 20 to move on the top of the sealing sleeve 4 through rotation inside the threaded sleeve 21. At the same time, the moving plate 20 will drive the load-bearing strip 22 to move outside the slide rails on both sides of the sealing sleeve 4, so that the moving plate 20 drives the movable plate 10 to move inside the sealing sleeve 4;

[0037] The zinc infiltration raw material is added into the inside of the feed hopper 17 from the upper end of the feed hopper 17, and enters the zinc melting furnace 1 after passing through the feed hopper 17. Due to the design of the feed hopper 17 with a narrow middle and wide ends, the flow of zinc powder can be accelerated, so that the zinc powder can cover the metal surface more quickly, avoiding the problems of accumulation or uneven distribution;

[0038] During the process of the zinc infiltration raw material passing through the inside of the feed hopper 17, an annular static eliminator composed of a fixed ring 18 and a contact 19 is arranged at the relatively narrow middle part of the feed hopper 17. During the process of the zinc infiltration raw material passing through the middle of the feed hopper 17, by applying high-voltage electricity to the contact 19, the static electricity of the zinc infiltration raw material is removed, preventing the zinc infiltration raw material from adhering to the inside of the feed hopper 17 due to static electricity.
