As a structure that uses the vacuum pressure difference for gripping, vacuum suction cups are suitable for gripping and transferring various types of material packaging boxes, metals, glass, etc. with flat surface structures.

[0003] For example, in the vacuum suction tool with the publication number CN218024140U that can be used for workpieces with irregular shapes, there are still the following deficiencies in actual use:

[0004] In the above patent, when the vacuum suction tool exhausts, it directly discharges through the exhaust holes. The high air flow velocity will generate a sharp sound, which is likely to cause noise pollution in the factory and affect the health of workers during long-term work. Utility Model Content

[0006] The low-noise vacuum suction tool provided by this application adopts the following technical solutions:

[0007] A low-noise vacuum suction tool includes a vacuum suction tool main body. The vacuum suction tool main body includes a mounting seat, and a noise reduction box is fixedly provided at one end of the mounting seat;

[0010] By adopting the above technical solutions, the setting of the noise reduction box and the noise reduction sponge can effectively buffer the air flow and at the same time absorb and convert the emitted sharp noise, thereby reducing the decibel of the noise.

[0011] Preferably, limiting protrusions are symmetrically and obliquely fixed on both sides inside the noise reduction box, and both sides of the noise reduction sponge are inserted on the surfaces of the two limiting protrusions.

[0012] By adopting the above technical solutions, the setting of the limiting protrusions can limit and fix the noise reduction sponge to prevent the noise reduction sponge from moving to generate gaps and cause noise.

[0013] Preferably, mounting through holes one are formed at the centers of the two limiting protrusions, and the mounting through holes one are arranged in a T shape.

[0014] By adopting the above technical solution, the noise reduction box 3 is fixed to the vacuum suction tool body 1 by the cooperation of the mounting through hole one and the long rod screw.

[0023] Preferably, arc chamfers two matching the structure of the arc chamfer one are formed at the corners of the noise reduction sponge. When the noise reduction sponge is inserted into the noise reduction box, the arc chamfer one abuts and seals.

[0024] By adopting the above technical solution, the arc chamfer two matches the arc chamfer one in structure to achieve fixation.

[0034] The following will Figures 1-5 make a further detailed description of this application.

[0035] The embodiment of this application discloses a low-noise vacuum suction tool.

[0036] Referring to Figure 1 , a low-noise vacuum suction tool includes a vacuum suction tool main body 1. The vacuum suction tool main body 1 is set as an existing and mature product, and its internal structure and principle will not be described in detail. The vacuum suction tool main body 1 includes a mounting seat 2 fixed on one side of the vacuum suction tool main body 1.

[0037] The setting of the mounting seat 2 can fix the noise reduction box 3 on the surface of the vacuum suction tool main body 1, thereby realizing the effect of buffering and absorbing sound for the air flow, and then realizing noise reduction and achieving low noise.

[0038] Referring to Figure 1 , Figure 2 , Figure 5, on both sides of the inner wall inside the noise reduction box 3, there are integrally formed limit protrusions 13. The two limit protrusions 13 are symmetrically arranged obliquely. At the center of the two limit protrusions 13, there are circular and through mounting perforations one 5. The structure of the mounting perforation one 5 is T-shaped, so that the head of the long rod screw 6 is located inside the larger hole of the mounting perforation one 5. On the surface of the mounting seat 2, there are a number of internal threaded holes 8. The number of internal threaded holes 8 corresponds to the number of mounting perforations one 5. Inside the mounting perforation one 5, there is a long rod screw 6 inserted movably. The long rod screw 6 is preferably a half-thread screw. The smooth surface of the long rod screw 6 is located inside the mounting perforation one 5, thereby increasing the contact surface and making the fixation of the noise reduction box 3 more stable. And the tail of the long rod screw 6 is provided with external threads, and the external threads are screwed into the internal threaded holes 8 to achieve threaded fixation. One end of the mounting seat 2 is fixed to one end of the noise reduction box 3.

[0039] The user aligns the mounting perforation one 5 of the noise reduction box 3 with the internal threaded holes 8 of the mounting seat 2, so that the exhaust hole two 7, the exhaust hole one 4 and the exhaust hole three 9 are aligned and communicated, enabling the gas to be discharged smoothly. Subsequently, the user inserts the long rod screw 6 into the mounting perforation one 5 and uses an electric tool to rotate the head of the long rod screw 6 to connect and fix the long rod screw 6 with the internal threaded holes 8. The noise reduction box 3 is tightly fixed on the mounting seat 2 through the head of the long rod screw 6 to prevent the noise reduction box 3 from detaching from the mounting seat 2 under the drive of the air flow.

[0040] Refer to Figure 3 , inside the noise reduction box 3, there is a detachable noise reduction sponge 14 inserted. The noise reduction sponge 14 is used for sound absorption and noise reduction. At the same time, the noise reduction sponge 14 can be set as an independent and relatively thick sponge to fill the inside of the noise reduction box 3, or it can be set as multiple thin sponges of a certain thickness. Specifically, if the depth of the inner cavity of the noise reduction box 3 is 5 cm, the thickness of each thin sponge can be set to 1 cm, and 5 thin sponges are stacked inside the noise reduction box 3. One end surface of the noise reduction sponge 14 abuts against the surface of the mounting seat 2 and fills the gap between the noise reduction box 3 and the mounting seat 2 to achieve sealing, thereby preventing the gas from flowing out of this gap and increasing the noise.

[0041] Refer to Figure 2 , Figure 4 , Figure 5 , on both sides of the surface of the mounting seat 2, there are symmetrically arranged exhaust holes two 7. The number of exhaust holes two 7 is set to a number of, and specifically, it needs to be set at least 4 according to the structural requirements of the vacuum suction tool main body 1. On the surface of the noise reduction sponge 14, there are a number of exhaust holes three 9. The number of exhaust holes three 9 corresponds to the number of exhaust holes two 7. On the outer surface of the noise reduction box 3, there are a number of exhaust holes one 4 corresponding to the exhaust holes three 9.

[0042] The high-speed air flow inside the vacuum suction tool main body 1 flows out through the second exhaust hole 7 of the mounting base 2 and enters the third exhaust hole 9 of the noise reduction sponge 14, and then is discharged to the outside through the first exhaust hole 4 of the noise reduction box 3. The noise reduction sponge 14 is a porous material, and its internal structure contains a large number of voids and pores. This porous structure is the key for the sponge to have noise reduction ability. When sound waves propagate to the surface of the sponge, the sound wave energy will be absorbed by these voids and pores and reflected and scattered multiple times inside the sponge. This process causes the attenuation of the sound wave energy, thus achieving the effect of noise reduction. At the same time, the semi-enclosed noise reduction box 3 also plays a role in sound insulation and noise reduction. After being processed by the noise reduction sponge 14 and the noise reduction box 3, the sharp sound can become low and not harsh.

[0043] Refer to Figure 5 , at the corresponding positions of the surfaces on both sides of the noise reduction sponge 14, limiting grooves 10 are provided. The structure of the limiting groove 10 matches the structure of the limiting protrusion 13, so that the limiting protrusion 13 can be inserted into the limiting groove 10, thereby fixing the noise reduction sponge 14 to prevent it from shaking under the disturbance of the air flow and affecting the noise reduction effect.

[0044] Refer to Figure 5 , arc chamfers one 12 are provided at the four inner wall corners inside the noise reduction box 3, and arc chamfers two 11 are provided at the corners of the noise reduction sponge 14. The arc chamfer two 11 matches the structure of the arc chamfer one 12 to achieve a fitting effect. When the noise reduction sponge 14 is inserted into the noise reduction box 3, the arc chamfer one 12 and the arc chamfer two 11 are in contact and sealed.

[0045] Insert the noise reduction sponge 14 into the noise reduction box 3 and make the arc chamfer two 11 contact the arc chamfer one 12 to achieve sealing. At the same time, insert the limiting groove 10 outside the limiting protrusion 13, thereby firmly fixing the noise reduction sponge 14 inside the noise reduction box 3.

[0046] The implementation principle of a low-noise vacuum suction tool in an embodiment of this application is as follows:

[0047] When the air inside the vacuum suction tool main body 1 quickly discharges to the outside through the second exhaust hole 7, the third exhaust hole 9, and the first exhaust hole 4, the air flow will inflate the noise reduction sponge 14, and the noise reduction effect is achieved by the characteristics of the noise reduction sponge 14 itself. At the same time, the provided noise reduction box 3 can also slow down the gas flow rate and thus reduce the noise. This device is installed at the exhaust end of the vacuum suction tool main body 1, which can avoid causing noise pollution in the factory and also avoid affecting the health of workers due to long-term work.

[0048] The above are all the preferred embodiments of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
