Description

Technical Field

[0001] This utility model relates to the field of steel pipe feeding technology, specifically a steel pipe powder coating feeding device. Background Technology

[0002] During the steel pipe production process, plastic powder is usually sprayed onto the surface of the steel pipe and cured at high temperature, so that the plastic powder is tightly bonded to the surface of the steel pipe to form a strong, beautiful and corrosion-resistant coating. During the powder coating process, the steel pipe is fed by a steel pipe powder coating feeding device. When feeding the steel pipe, the feeding device positions the steel pipe on the positioning rod of the feeding rack and conveys the steel pipe through the guide rail, smoothly conveying the steel pipe into the powder coating machine along the preset path.

[0003] In common steel pipe powder coating feeding devices, the feeding rack is positioned below the guide rail by a chain. When the guide rail transports the feeding rack and steel pipe, the chain will cause the feeding rack and steel pipe to shake. The shaking feeding rack and steel pipe may affect the powder coating effect. Therefore, a steel pipe powder coating feeding device is proposed to address the above problem. Utility Model Content

[0004] The purpose of this invention is to provide a feeding device for steel pipe powder coating, so as to solve the problem that a shaking feeding rack and steel pipe may affect the powder coating effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

An electric telescopic rod is installed at the bottom of each moving block. A fixed block is fixedly connected to the end of the electric telescopic rod away from the moving block. A symmetrically arranged mounting plate is fixedly connected to the bottom of the fixed block. A mounting shaft is rotatably connected to the inner side of the mounting plate. A connecting block is fixedly connected to the outer side of the mounting shaft. A feeding rack with an inverted L-shape is provided at the bottom of the connecting block. Several evenly arranged positioning rods are provided on the outer side of the feeding rack. Evenly arranged sliding grooves are formed on the inner side of the mounting shaft. A slider is slidably connected to the inner side of the sliding grooves. A ring-shaped pulling block is fixedly connected to the outer side of the slider. An insert block is fixedly connected to one side of the pulling block. Several evenly arranged slots are formed on one side of the mounting plate. The insert block is disposed inside some of the slots.

[0007] Preferably, the pull block is disposed on the outside of the mounting shaft, one end of the mounting shaft penetrates through the mounting plate, and a limit block is fixedly connected to the end of the mounting shaft penetrating through the mounting plate.

[0008] Preferably, the bottom of the connecting block has a slot, and a locking block is engaged inside the slot. The locking block is fixedly connected to the feeding frame, and the locking block and the connecting block are detachably connected by bolts.

[0009] Preferably, the inner side of the feeding rack is fixedly connected with a plurality of evenly arranged threaded sleeves, and some of the threaded sleeves are threadedly connected to a screw rod, which is fixedly connected to a positioning rod.

[0029] Please see Figure 1-9 This utility model provides a technical solution:

[0030] A feeding device for powder coating of steel pipes includes a guide rail 1, bolts 17, and moving blocks 20. Several evenly arranged moving blocks 20 are installed at the bottom of the guide rail 1. An electric telescopic rod 2 is installed at the bottom of each moving block 20. A fixing block 3 is fixedly connected to the end of the electric telescopic rod 2 away from the moving block 20. A symmetrically arranged mounting plate 4 is fixedly connected to the bottom of the fixing block 3. A mounting shaft 5 is rotatably connected to the inner side of the mounting plate 4. A connecting block 6 is fixedly connected to the outer side of the mounting shaft 5. A feeding rack 7 with an inverted L-shape is provided at the bottom of the connecting block 6. A feeding rack 7 with... There are several evenly arranged positioning rods 8. The inner side of the mounting shaft 5 is provided with evenly arranged sliding grooves 9. The inner side of the sliding grooves 9 is slidably connected to a slider 10. The outer side of the slider 10 is fixedly connected to a ring-shaped pull block 11. One side of the pull block 11 is fixedly connected to an insert block 12. One side of the mounting plate 4 is provided with several evenly arranged slots 13. The insert block 12 is located inside some of the slots 13. This arrangement can greatly reduce the shaking of the feeding rack 7 and steel pipe during transportation, and solve the problem that the shaking feeding rack 7 and steel pipe may affect the powder coating effect.

[0031] Pull block 11 is located on the outside of mounting shaft 5. One end of mounting shaft 5 passes through mounting plate 4. Limit block 14 is fixedly connected to the end of mounting shaft 5 that passes through mounting plate 4. This arrangement allows the pull block 11 to be limited by the limit block 14, preventing the pull block 11 from detaching from mounting shaft 5. The bottom of connecting block 6 has a slot 15. A locking block 16 is engaged with the inside of the slot 15. The locking block 16 is fixedly connected to the feeding rack 7. The locking block 16 and connecting block 6 are detachably connected by bolts 17. This arrangement allows for the detachable installation of feeding rack 7. Several evenly arranged threaded sleeves 19 are fixedly connected to the inside of feeding rack 7. Some threaded sleeves 19 are threadedly connected to screw rods 18. Screw rods 18 are fixedly connected to positioning rods 8. This arrangement allows for the detachable installation of positioning rods 8. Feeding racks 7 are grouped in pairs, mounting plates 4 are grouped in pairs, and connecting blocks 6 are located between groups of mounting plates 4. This arrangement allows for the positioning of connecting blocks 6.

[0032] Workflow: All electrical appliances in this invention are equipped with an external power supply or a built-in battery. When feeding steel pipes through the steel pipe powder coating feeding device, the operator controls the extension of the electric telescopic rod 2 through the external control device. This causes the electric telescopic rod 2 to move the fixed block 3, mounting plate 4, mounting shaft 5, connecting block 6, feeding rack 7, and positioning rod 8, thereby lowering the height of the feeding rack 7 and positioning rod 8, making it easier for the operator to place the steel pipes. Then, the pull block 11 is pulled towards the limit block 14, causing the pull block 11 to move the slider 10 and the insertion block 12. The slider 10 slides inside the groove 9, and the insertion block 12 gradually disengages from the slot 1. 3. This removes the restriction on the mounting shaft 5, allowing it to rotate with the mounting plate 4. The mounting shaft 5 drives the connecting block 6, the feeding rack 7, and the positioning rod 8 to rotate, facilitating the sequential insertion of steel pipes onto the outside of the positioning rod 8. The steel pipes are placed using a symmetrically arranged feeding rack 7. After placement, the feeding rack 7 is positioned vertically, and the pull block 11 is pushed, re-inserting the insertion block 12 into the slot 13, thus limiting the insertion block 12. The limiting block 14 limits the pull block 11, preventing it from detaching from the mounting shaft 5. Then, the external control device of the guide rail 1 drives the moving block 20 to move along the direction of the guide rail 1. The moving block 20 smoothly transports the fixed block 3, mounting plate 4, mounting shaft 5, connecting block 6, feeding rack 7, positioning rod 8, and steel pipe into the powder coating machine for the powder coating process. The electric telescopic rod 2, through precise motor control, achieves smooth, wobbly telescopic movement, greatly reducing the shaking of the feeding rack 7 and steel pipe during transportation and solving the problem that shaking of the feeding rack 7 and steel pipe might affect the powder coating effect. The outer shell of the electric telescopic rod 2 is made of aluminum-magnesium alloy, which is lightweight, high-strength, and has good corrosion resistance. It also has good heat dissipation performance, helping to maintain the stable operation of the internal motor of the electric telescopic rod 2, thus ensuring smooth powder coating. When the plastic injection molding machine sprays the steel pipe, it will not affect the performance of the electric telescopic rod 2. When the feeding rack 7 needs to be replaced, remove the bolt 17 and then pull the feeding rack 7 away from the connecting block 6. This will cause the feeding rack 7 to move the locking block 16. The locking block 16 will gradually disengage from the locking groove 15, thereby disassembling the feeding rack 7. The reverse operation can be used to install the new feeding rack 7. When the positioning rod 8 needs to be replaced or its position changed, rotate the positioning rod 8. This will cause the positioning rod 8 to drive the screw 18 and the screw sleeve 19 to spiral, thereby disassembling the positioning rod 8 and the screw 18. The reverse operation can be used to install the positioning rod 8 and the screw 18.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
