Description

Technical Field

[0001] This utility model relates to the field of sandblasting machine technology, specifically an adjustable sandblasting machine. Background Technology

[0002] A sandblasting machine is a machine that removes particulate matter from dusty gas. It mainly uses compressed air to drive abrasive or shot to spray onto the surface of the workpiece. The abrasive performs micro-cutting or impact on the workpiece surface to achieve rust removal, paint removal, surface impurity removal, surface strengthening, and various decorative treatments.

[0003] In order to achieve good sealing and stability, existing sandblasting machines mostly use welding to connect the sandblasting machine and the hose. However, when the sandblasting machine is working, it generates a high-pressure sandblasting flow, which will have a strong impact on the inner and outer walls of the hose. Long-term impact may cause wear on the inner wall of the hose or even breakage. At this time, it becomes relatively difficult to disassemble and replace the hose. To address this, we propose an adjustable sandblasting machine. Utility Model Content

[0004] One of the technical problems this application aims to solve is the inconvenience of disassembling and assembling the sandblasting machine and the hose during use.

The upper end of the mounting frame body is snapped with a feeding cylinder, and the lower end of the feeding cylinder is provided with a discharge pipe. A feeding pipe is provided on one side of the discharge pipe, and a rotating nozzle is provided at one end of the feeding pipe. A snap-fit ​​component is provided between the discharge pipe and the feeding pipe, and between the feeding pipe and the rotating nozzle. The snap-fit ​​component is used to facilitate the disassembly and assembly of the discharge pipe and the feeding pipe.

[0007] In some embodiments, a circular hole is provided on one side surface of the snap-fit ​​cylinder. There are eight circular holes arranged in a circumferential array. A limiting ball is movably connected inside the circular hole. There are eight limiting balls, each corresponding to one of the circular holes.

[0008] In some embodiments, an inner groove is formed on one side surface of the snap-fit ​​cylinder, and a snap-fit ​​washer is provided on the outer side of the inner groove, with one end of the snap-fit ​​washer snapped into the inner side of the inner groove.

[0009] In some embodiments, the internal snap-fit ​​component includes an internal post, a connecting tube head is fixedly connected to the middle of the internal post, a first splicing groove is formed on one side surface of the internal post, a second splicing groove is formed on one side surface of the snap-fit ​​washer, the inner part of the snap-fit ​​washer is snap-fitted into the inside of the first splicing groove, and the outer part of the internal post is snap-fitted into the inside of the second splicing groove.

[0010] In some embodiments, a guide plate is fixedly connected inside the actuating cylinder, and one end of the connecting tube is snapped into the inside of the guide plate.

[0011] In some embodiments, a pressure gauge is fixedly connected to the upper end of the discharge cylinder, and an inlet pipe is provided at the rear end of the pressure gauge. The inlet pipe is located on one side surface of the upper end of the discharge cylinder, and a caster wheel is fixedly connected to the lower end of the mounting frame body.

A pipe clamping groove is provided on one side surface of the pipe clamping plate. There are two pipe clamping grooves arranged symmetrically.

[0013] This utility model has at least the following beneficial effects:

[0014] 1. This utility model uses the rearward movement of the actuating cylinder to retract the return spring, and at the same time, the pressure on the limiting ball inside the actuating cylinder disappears, allowing the limiting ball to move inside the circular hole. At this time, the limiting inside the locking cylinder disappears, which facilitates the insertion of the inner column into the locking cylinder. Then, the return spring resets the actuating cylinder, so that the limiting ball is subjected to inward pressure. The limiting ball tightly locks the inner column, thus realizing quick assembly and disassembly between the discharge pipe and the feed pipe, as well as quick assembly and disassembly between the feed pipe and the rotating nozzle.

[0015] 2. This utility model allows for quick replacement of the feed pipe and rotary nozzle. By replacing the feed pipe with different sizes, the conveying speed and flow rate of the sand can be adjusted to meet the sandblasting efficiency requirements of different operating scenarios.

Example

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution: an adjustable sandblasting machine, including a mounting frame body 1, a feeding cylinder 2 is snapped to the upper end of the mounting frame body 1, a discharge pipe 3 is provided at the lower end of the feeding cylinder 2, a feeding pipe 5 is provided on one side of the discharge pipe 3, and a rotating nozzle 6 is provided at one end of the feeding pipe 5.

[0025] The snap-fit ​​assembly 4 includes an inner snap-fit ​​component 8, and an outer snap-fit ​​component 7 is provided on the outside of the inner snap-fit ​​component 8. The outer snap-fit ​​component 7 includes a snap-fit ​​cylinder 9, and an actuating cylinder 13 is sleeved on the outer surface of the snap-fit ​​cylinder 9. A return spring 11 is movably connected between the snap-fit ​​cylinder 9 and the actuating cylinder 13. The return spring 11 is used to facilitate the reset of the actuating cylinder 13. There are limit portions between the snap-fit ​​cylinder 9 and the actuating cylinder 13 to limit the return spring 11 and facilitate its use.

[0026] The snap-fit ​​cylinder 9 has eight circular holes 10 on one side surface, arranged in a circumferential array. The inside of the circular holes 10 is movably connected to the limiting beads 12. There are eight limiting beads 12, which correspond one to one of the circular holes 10. The limiting beads 12 can be raised and lowered inside the circular holes 10 to achieve the overall limiting effect. By controlling the position of the limiting beads 12 inside the circular holes 10, the snap-fit ​​operation of the snap-fit ​​component 4 can be more effectively realized.

[0027] An inner groove 14 is provided on one side surface of the snap-fit ​​cylinder 9, and a snap-fit ​​washer 15 is provided on the outer side of the inner groove 14. One end of the snap-fit ​​washer 15 is snapped into the inner side of the inner groove 14. The whole is to achieve a tight connection between the inner snap-fit ​​component 8 and the outer snap-fit ​​component 7.

[0028] The internal snap-fit ​​component 8 includes an inner post 16, with a connecting pipe head 17 fixedly connected to the middle of the inner post 16. The connecting pipe head 17 is connected to one end of the discharge pipe 3 and the feed pipe 5, respectively. The snap-fit ​​cylinder 9 is connected to the other end of the feed pipe 5 and the interior of the rotating nozzle 6, respectively. A first splicing groove 18 is opened on one side surface of the inner post 16, and a second splicing groove 19 is opened on one side surface of the snap-fit ​​washer 15. The inner part of the snap-fit ​​washer 15 is snapped into the interior of the first splicing groove 18, and the outer part of the inner post 16 is snapped into the interior of the second splicing groove 19.

[0029] The inside of the actuating cylinder 13 is fixedly connected to the guide plate 20, and one end of the connecting tube head 17 is snapped into the inside of the guide plate 20, making the overall splicing more precise.

[0030] A pressure gauge 21 is fixedly connected to the upper end of the discharge cylinder 2. A feed pipe 22 is provided at the rear end of the pressure gauge 21. The feed pipe 22 is located on one side surface of the upper end of the discharge cylinder 2. A caster wheel 23 is fixedly connected to the lower end of the mounting frame body 1. Example

[0031] Please see Figure 6 This utility model provides a technical solution:

[0032] Unlike Embodiment 1, a set of tube clamping plates 24 are fixedly connected to both sides of the mounting frame body 1. There are two tube clamping plates 24 arranged symmetrically. The tube clamping plates 24 are used to wind and store the feed tube 5. A tube clamping groove 25 is opened on one side surface of the tube clamping plate 24. There are two tube clamping grooves 25 arranged symmetrically. The tube clamping groove 25 is used to lock and limit the rotating nozzle 6 at the end of the feed tube 5, which facilitates the storage and placement of the whole.

[0033] Before using the sandblasting machine, the required sandblasting material is poured into the discharge cylinder 2 through the feed pipe 22. One end of the discharge pipe 3 is tightly connected to an external pressure pump, and the internal pressure is displayed using the pressure gauge 21. When using the entire device, the appropriate size is selected and replaced as needed. By pushing the actuating cylinder 13 backward, the return spring 11 is retracted, and at the same time, the pressure on the limiting ball 12 inside the actuating cylinder 13 disappears, allowing the limiting ball 12 to move inside the circular hole 10. At this time, the limiting inside the locking cylinder 9 disappears, making it convenient for the inner connecting post 16 to be inserted into the inside of the locking cylinder 9. Then, the return spring 11 resets the actuating cylinder 13, causing the limiting ball 12 to be subjected to inward pressure. The limiting ball 12 tightly engages the inner connecting column 16, thus achieving quick assembly and disassembly between the discharge pipe 3 and the feed pipe 5, as well as between the feed pipe 5 and the rotating nozzle 6. Appropriate dimensions for the feed pipe 5 and the rotating nozzle 6 can reduce equipment wear and failure rate. Regular replacement and adjustment of dimensions ensure the equipment is always in optimal working condition, extending its service life. Whether for large-area cleaning or fine operations, the sandblasting machine can meet requirements by replacing parts, without needing to replace the entire machine. This reduces equipment purchase costs and improves equipment utilization.
