Description

Technical Field

[0001] This utility model belongs to the field of shot blasting machine technology, specifically, it relates to a shot blasting machine painting fixture. Background Technology

[0002] Shot blasting machines are industrial equipment for pre-treatment of steel surfaces. They are mainly used for rust removal, descaling, and pre-painting treatment of welded parts, H-beams, profiles, and steel plates. They can improve material adhesion and fatigue resistance and are widely used in shipbuilding, steel structure engineering, automobiles, and bridges.

[0003] The entire production line consists of a feeding roller conveyor system, a shot blasting system, a spraying system, a dust removal and environmental protection system, and a paint VOC catalytic combustion treatment system. The spraying system is a crucial component of the pretreatment line. After rust removal and cleaning, steel plates, profiles, and components are sprayed using paint sprayers. The spray booths in the spraying system are thin-walled box-shaped structures. The spraying (paint mist generation area) is located in a single chamber. The upper spray gun drive and detection are located above the spray booth, while the lower spray gun drive is in another chamber. A roller conveyor in the middle carries the steel plates through the spray booth, ensuring that these devices completely avoid paint mist interference and facilitate the removal of paint residue. However, existing roller conveyors mostly use a structure with threaded grooves or threaded protrusions on their outer surface to improve anti-slip performance and reduce the contact area between the outer surface of the roller and the steel plate, thus enabling the conveying and painting of the steel plate. However, after a long painting time, paint tends to accumulate in the threaded grooves or threaded gaps. When the threaded grooves or threaded gaps are blocked, a large part of the steel plate will be obstructed during transport, making it easy for the part under the steel plate to be poorly painted. In addition, the paint in these threaded grooves or threaded gaps is not easy to clean, and if replacement is required, the cost is relatively high, as each roller needs to be disassembled. Therefore, the current roller conveyors have many disadvantages. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a shot blasting machine painting fixture.

[0005] To achieve the aforementioned utility model objective, the technical solution adopted by this utility model includes: a shot blasting machine painting fixture, including a frame, a roller conveyor on the frame, the roller conveyor being composed of several rollers arranged at intervals, each roller being able to rotate on the frame for conveying steel plates, which is a complete conveying roller conveyor in the prior art, and will not be described in detail here;

[0006] Each roller is equipped with several adjustable steel plate supports to support the steel plate, and these supports are adjustable to each other. Each steel plate support includes a hoop and a support protrusion. The free ends of the hoop are connected by bolts and nuts, which also install the hoop on the roller to support the steel plate and facilitate disassembly. In the event of excessive paint buildup, the hoop can be easily removed for cleaning, and the smooth roller can also be cleaned easily. There are several support protrusions, evenly arranged radially along the outer surface of the hoop. The support protrusions are detachably set outside the hoop, and their height can be changed as needed, making them more flexible in use. The support protrusions support the steel plate, replacing the traditional threaded grooves and exposed threaded protrusions, reducing the contact area with the steel plate, increasing anti-slip performance, and ensuring stable steel plate conveying.

[0007] Furthermore, the support protrusion includes a fulcrum and a bolt. The bolt is fixed at one end of the fulcrum, and the hoop has bolt holes for threaded connection with the bolt. The simple threaded connection makes it easy to replace and easy to manufacture.

[0008] Furthermore, the clamp body includes a first part and a second part, which are fitted together to clamp the outside of the roller. Both ends of the first part and the second part are provided with connecting blocks, and each of the opposite connecting blocks has at least one threaded hole. The opposite threaded holes are connected by adjusting bolts to fix the first part and the second part. Preferably, there are two threaded holes located at both ends of the connecting blocks. The adjusting bolts are also in two sets. By adjusting the threads, the first part and the second part are locked, so that the first part and the second part form a complete clamp. The clamp body has a split structure (first part + second part) and is fixed by adjusting bolts, which is convenient for installation and partial replacement without the need to disassemble the entire roller conveyor.

[0009] Furthermore, the volume of the fulcrum gradually decreases from one end near the bolt to the other, and the free end of the fulcrum is smoothly transitioned to minimize the contact area with the steel plate. This allows for a larger spraying area on the steel plate during the spraying process.

[0010] Furthermore, it also includes several limiting grooves evenly opened along the radial direction of the roller, and the inner surface of the hoop is provided with limiting protrusions that can be inserted into the limiting grooves to prevent the hoop from rotating during the conveying process and causing conveying accidents.

[0011] Compared with the prior art, the advantages of this utility model include:

[0012] (1) The present invention provides a shot blasting machine painting fixture, which uses a detachable steel plate support (hoop body + support protrusion) to replace the traditional threaded groove / threaded protrusion roller, thereby reducing the obstruction of steel plate spraying.

[0013] The hoop is fixed with bolts and nuts, allowing for quick disassembly and cleaning; after disassembly, the smooth roller surface has no complex structure, making it easier to remove paint and reducing maintenance costs.

[0014] (2) The present invention provides a shot blasting machine painting fixture with adjustable support protrusion height (replaceable by bolt connection) to adapt to different steel plate thicknesses or painting requirements; the steel plate support spacing is adjustable, optimizing the distribution of support points and improving adaptability to steel plates of different sizes.

[0015] (3) The shot blasting machine painting fixture provided by this utility model has radially uniformly arranged support protrusions to reduce the contact area with the steel plate, while the smooth design of the fulcrum prevents scratching the steel plate. The limiting groove cooperates with the protrusion to prevent the hoop from rotating, ensuring the stability of the conveying and avoiding deviation accidents. Attached Figure Description

[0028] Furthermore, to provide the public with a better understanding of this utility model, certain specific details are described in detail in the following description. However, those skilled in the art can fully understand this utility model even without these detailed descriptions.

[0029] Example 1

[0030] Please see Figure 1 and Figure 3 A shot blasting machine painting fixture includes a frame 11, a roller conveyor 12 on the frame 11, the roller conveyor 12 being composed of a number of rollers 13 arranged at intervals, each roller 13 being able to rotate on the frame 11 for conveying steel plates.

[0031] Each roller 13 is equipped with several adjustable steel plate supports 14 for supporting the steel plate, and these supports are adjustable to each other. Each steel plate support 14 includes a hoop 15 and a support protrusion 16. The free ends of the hoop 15 are connected by bolts 18 and nuts, which also install the hoop 15 on the roller 13 to support the steel plate and facilitate disassembly. In the event of excessive paint accumulation, the hoop 15 can be disassembled for easy cleaning, and the smooth roller 13 can also be easily cleaned. There are several support protrusions 16, which are evenly arranged radially along the outer surface of the hoop 15. The support protrusions 16 are detachably set on the outside of the hoop 15, and their height can be changed as needed, making them more flexible in use. The support protrusions 16 support the steel plate, replacing the traditional threaded grooves and exposed threaded protrusions, reducing the contact area with the steel plate, increasing anti-slip performance, and ensuring stable steel plate conveying.

[0032] The support protrusion 16 includes a fulcrum 17 and a bolt 18. The bolt 18 is fixed at one end of the fulcrum 17. The hoop 15 has a bolt hole for threaded connection with the bolt 18. The simple threaded connection makes it easy to replace and easy to manufacture.

[0033] The clamp 15 includes a first part 21 and a second part 22, which cooperate to clamp the outside of the roller 13. Both ends of the first part 21 and the second part 22 are provided with connecting blocks 23. Each of the opposite connecting blocks 23 has at least one threaded hole 24. The opposite threaded holes 24 are connected by adjusting bolts 18 to fix the first part 21 and the second part 22. Preferably, there are two threaded holes 24, located at both ends of the connecting blocks 23. The adjusting bolts 18 are also in two sets. By adjusting the threads, the first part 21 and the second part 22 are locked, so that the first part 21 and the second part 22 form a complete clamp. The clamp 15 has a split structure (first part 21 + second part 22) and is fixed by adjusting bolts 18, which facilitates installation and partial replacement without the need to disassemble the roller conveyor 12 as a whole. When a single support protrusion 16 is damaged, it can be replaced independently, reducing spare parts costs.

[0034] The volume of the fulcrum 17 gradually decreases from one end near the bolt 18 to the other end. The free end of the fulcrum 17 is smoothly transitioned to minimize the contact area with the steel plate, so that the steel plate can be sprayed with a larger area during the spraying process.

[0035] It also includes several limiting grooves 25 evenly opened along the radial direction of the roller 13, and the inner surface of the hoop 15 is provided with limiting protrusions that can be inserted into the limiting grooves 25 to prevent the hoop 15 from rotating during the conveying process, which could lead to a conveying accident.

[0036] Working principle:

[0037] For example, the steel plate is supported by multiple adjustable-spacing steel plate supports 14 on the roller conveyor 12, and the support protrusions 16 make point contact with the steel plate to reduce the shading area.

[0038] When the roller 13 rotates, the hoop 15 is fixed to the groove of the roller 13 by the limiting protrusion to prevent slippage and ensure the smooth conveying of the steel plate.

[0039] During spraying, the paint mist mainly adheres to the surface of the smooth roller 13 and the detachable hoop 15. The support protrusion 16 is less prone to paint accumulation due to its small contact area and detachable design.

[0040] Adjusting the bolt 18 changes the tightness of the hoop 15 or the position of the support protrusion 16, optimizing the distribution of support force and adapting to steel plates of different weights or sizes.

[0041] In this way,

[0042] This invention significantly improves coating coverage, reduces paint waste, and also reduces equipment maintenance difficulty and downtime.

[0043] It should be understood that the above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. It should not be considered that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art to which this utility model pertains, several simple deductions or substitutions can be made without departing from the concept of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
