The invention provides an automatic feeding and stacking mechanism for pre-treatment of hot-dip galvanizing of steel pipes, comprising:

The No. 1 conveyor 100 includes a support frame 101. The support frame 101 is provided with a chain 102. The chain 102 is in driving cooperation with the sprocket 103. The sprocket 103 is connected to the motor 105 through the transmission shaft and the coupling 104, and passes through the No. 1 conveyor. 100 and No. 2 conveyor 300 complete the conveying operation of materials;

The lifting and clamping mechanism 200 is arranged at the front end of the No. 1 conveyor 100 in order to facilitate the manual unbundling of the steel pipe sling, the structure design is simple, the installation is convenient, the work efficiency is improved, and the labor intensity of workers is reduced;

The working process of the lifting and clamping mechanism 200: the material moves from the No. 1 conveyor 100. There is a height difference between the No. 1 conveyor 100 and the No. 2 conveyor 300. When a bundle of steel pipes falls from the No. 1 conveyor 100 to the No. 2 conveyor When the machine is 300, the No. 1 conveyor 100 and the No. 2 conveyor 300 stop moving, the steel pipe is positioned in the middle of the clamping jaws 205 on both sides of the lifting and clamping mechanism 200, and the lifting cylinder 202 in the lifting and clamping mechanism 200 is at this time. Action, lift the bundle of steel pipes and leave the No. 2 conveyor 300. After the lifting is in place, the clamping cylinder 206 moves to clamp the bundle of steel pipes. After the steel pipes are clamped, they shrink. , and then the clamping cylinder 206 is released, the jacking cylinder 202 is lowered, and the bundled steel pipes are spread out onto the No. 2 conveyor 300 to complete the unpacking action of the steel pipes.

The No. 2 conveyor 300, the No. 2 conveyor 300 has the same structure as the No. 1 conveyor 100;

The self-weight material blocking mechanism 400, the self-weight material blocking mechanism 400 is arranged between the No. 1 conveyor 100 and the No. 2 conveyor 300;

The working process of the self-weight material blocking mechanism 400: When the steel pipe is conveyed from the No. 2 conveyor 300, it may cause the steel pipe to be skewed. When the steel pipe is skewed, one end will first hit the gravity swing rod 404. At this time, the steel pipe has a relatively large resistance and is very If it is difficult to move forward, the other end can continue to move forward under the conveyance of the conveyor. When both ends of the steel pipe touch the gravity swing rod 404, the steel pipe will roll over the gravity swing rod 404 driven by the conveyor, which plays the role of automatic alignment of the steel pipe. In order to adapt to steel pipes of different diameters, adjust the number of lifting screws 403 and add gravity swing rods 404 to meet the needs of different diameters

The mobile feeder 500 is set at the front end of the No. 2 conveyor 300;

The working process of the mobile material truck 500: the steel pipe is transported from the No. 2 conveyor 300 to the material blocking bracket 507, one side of the material blocking bracket 507 is fixed, and the other side is driven by the deceleration motor 505 to move backwards, and the material blocking bracket 507 is in The distance is very close at the beginning, and the steel pipe falls into the material blocking bracket 507. When several steel pipes are piled up in the material blocking bracket 507, there is a shooting sensor (not shown in the figure) above the material blocking bracket 507 to detect when the material is full. , the deceleration motor 505 moves, and moves backward with one side material blocking bracket 507, and the distance of movement is the diameter of a steel pipe. When the material blocking bracket 507 moves, the inner space of the two material blocking brackets 507 increases, and the steel pipe will fill the gap. , the height drops, the front conveyor continues to fall, and the support continues to move backward when it is full.

This set of mechanisms can feed three or four packs of steel pipes at the same time, and meet the output requirement of 60 tons per hour;

The safety fence 600 is provided on the periphery of the above-mentioned mechanism to play a protective role.

The lifting and clamping mechanism 200 includes an installation bottom plate 201 . The mounting bottom plate 201 is provided with a lifting oil cylinder 202 oppositely and vertically.

Two sets of clamping jaws 205 are slidably arranged on the guide rail 204 , and the clamping jaws 205 are connected by a clamping oil cylinder 206 .

The self-weight material blocking mechanism 400 includes a frame 401. The frame 401 is provided with a horizontal hanger rod 402. The two ends of the horizontal hanger rod 402 are threaded with lifting screws 403. The bottom end of the horizontal hanger rod 402 is symmetrically provided with a gravity swing rod 404.

The mobile cart 500 includes a rectangular base frame 501 , and guide rails 503 are provided on both sides of the inner wall of the rectangular base frame 501 .

The reduction motor 505 is connected to the rack and pinion 504 through a transmission structure 506 , and the rack and pinion structure in the rack and pinion 504 is fixed on the rectangular chassis 501 .

The front end of the rectangular base frame 501 is symmetrically provided with material blocking brackets 507 on both sides, and the material blocking brackets 507 are vertically arranged.

Implementation process: The operator uses the manual crane hook to lift the package of steel pipes in the storage area. Each time multiple packages are lifted, the weight of each package is different according to the diameter of the steel pipe, and 3-4 packages of materials can be lifted at a time. It can meet the requirements of pickling output; put the hoisted package material directly on the No. 1 conveyor.

2. There is a detection switch on the No. 1 conveyor 100. When it is detected that the material is manually hoisted and placed, the No. 1 conveyor 100 starts to feed the material.

3. When the first package material rolls down from the No. 1 conveyor 100 to the No. 2 conveyor 300, the photoelectric switch detects that the material is in place, the lifting and clamping mechanism 200 starts to work, the lifting cylinder 202 is lifted, and the two sides are clamped. The clamping jaw 205 clamps a package of materials, and manually removes the packaged nylon sling from both ends of the steel pipe.

4. Manually confirm that the strapping strap is removed, press the start button, the lifting and clamping mechanism 200 begins to fall, a package of steel pipes is spread over the No. 2 conveyor 300 in a scattered state, and the No. 2 conveyor 300 starts to work.

5. To prevent the folding of the steel pipe, the self-weight material blocking mechanism 400 has a gravity swing rod 404, so that the single layer or double layer of the steel pipe slowly falls into the moving material cart 500. When the moving material cart 500 detects that the material is full, it automatically moves back. One step, until the whole package is finished, then the No. 1 conveyor 100 is started, and the above process is repeated until all the three packages fall on the mobile truck 500, and the three packages are manually put on the nylon sling and hoisted to the pickling room. Pickle.
