Description

Technical Field

[0001] This utility model relates to the field of air shaft technology, specifically a low-noise multi-axis integrated air shaft. Background Technology

[0002] An air shaft is a specially designed winding and unwinding shaft. It's a shaft whose surface protrudes after being inflated by high pressure and quickly retracts after deflating. The air shaft mainly consists of a shaft core, an air bladder, and a key bar. Its working principle is as follows: the core components of the air shaft include an inflatable air bladder and a shaft with a key bar. When compressed air enters the air bladder through the nozzle, the air bladder expands, pushing the key bar outwards, increasing the shaft diameter, and thus tightly supporting the inner hole of the roll material, securing the roll material. During unwinding, the air in the air bladder is released, the key bar retracts, and the shaft diameter decreases, making it easier to remove the roll material. This design makes loading and unloading the roll material easy and quick, greatly improving production efficiency. A multi-shaft integrated air shaft mainly consists of multiple air shaft units, a common shaft support structure, and a centralized inflation system. Multiple air shaft units are arranged closely along the axial direction and share the same support structure, making them a whole. However, existing multi-axis integrated air shafts generate a lot of noise during operation due to gas flow during the inflation and deflation of the air bladder, friction between the air shaft components, and interaction with the roll material. This affects the working environment, may affect the operator's hearing, and is inconvenient to use. Summary of the Invention

[0003] The purpose of this invention is to provide a low-noise multi-axis integrated air shaft to solve the problems mentioned in the background art, such as affecting the working environment, potentially affecting the operator's hearing, and being inconvenient to use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a low-noise multi-axis integrated air shaft, including a base, on which rollers are mounted around the surface of the base;

[0005] The base surface is provided with a sound-absorbing structure, which includes: a groove embedded in the surface of the base, a soundproof cover installed on one side of the base surface, a cover rotatably installed on the surface of the soundproof cover, and openings embedded at equal intervals on the surface of the soundproof cover.

[0006] Preferably, one side of the soundproof cover is disposed inside the groove, and the soundproof cover and the groove are slidably connected.

[0007] Using the above technical solution, rotating the soundproof cover causes the opening to rotate, making it convenient to roll up items on the surface of the air shaft.

[0008] Preferably, the soundproof cover is arranged around the outside of the roller, and one side of the cover is rotatably connected to the soundproof cover.

[0009] By adopting the above technical solution, the soundproof cover can absorb sound from the roller and reduce the noise during roller use.

[0010] Preferably, the roller has a surface inflation structure, and the inflation structure includes: a groove is provided inside the roller, and a chamber is installed on the inner wall of the groove, and two sets of airbags are symmetrically arranged on the surface of the chamber; multiple locking blocks are symmetrically embedded at both ends of the roller; airbags are symmetrically connected to the surface of the chamber; a placement groove is symmetrically embedded on the surface of the roller, and a push block is connected inside the placement groove; and the end of airbag is connected to the push block.

[0011] Using the above technical solution, the inflatable structure can fix the two sides of the roll material and the roll position.

[0012] Preferably, the roller and the locking block are slidably connected, and the locking block is configured with an arc-shaped structure.

[0013] Using the above technical solution, once the airbag inflates, it pushes the locking block outward, causing the end of the locking block to move outward on the roller surface.

[0014] Preferably, one end of the airbag penetrates the surface of the roller and is connected to the locking block, and the locking block is embedded in the surface of the roller.

[0015] Using the above technical solution, when gas is injected into the chamber, the gas enters the airbag through the chamber.

[0016] Preferably, the two ends of the airbag are connected to the push block, and the push block and the placement groove are slidably connected.

[0017] Using the above technical solution, gas enters the interior of airbag two, and airbag two pushes the pusher outward.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the low-noise multi-axis integrated air shaft:

[0019] 1. A sound-absorbing structure is set up, with a soundproof cover surrounding the outside of the roller. This allows the soundproof cover to effectively absorb the noise generated when the roller is working, reducing the impact of noise on the working environment and improving the practicality and comfort of the device.

[0020] 2. An inflatable structure is provided. When the first airbag inflates, it pushes the arc-shaped locking block outward, fixing both sides of the roll material between the two locking blocks. The second airbag is connected to the push block in the placement groove. After the gas enters the second airbag, it pushes the push block, causing the push block to contact the inner hole of the roll material. This can tightly lock the inner hole of the roll material, strengthen the stability of the position during unwinding, improve the stability and precision of the roll material processing, and ensure production quality.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-5 This utility model provides a technical solution: a low-noise multi-axis integrated air shaft, including a base 10, a groove 20, a soundproof cover 201, a cover 202, an opening 203, a roller 30, a hollow groove 301, a chamber 401, an airbag 1 402, a locking block 403, an airbag 2 404, a placement groove 405, and a push block 406;

[0032] This multi-axis integrated air shaft facilitates sound insulation. The specific implementation method is as follows:

[0033] A roller 30 is mounted around the surface of the base 10. The surface of the base 10 is provided with a sound-absorbing structure, which includes: a groove 20 embedded in the surface of the base 10; a soundproof cover 201 mounted on one side of the surface of the base 10; a cover 202 rotatably mounted on the surface of the soundproof cover 201; openings 203 are equidistantly embedded in the surface of the soundproof cover 201; one side of the soundproof cover 201 is located inside the groove 20; the soundproof cover 201 and the groove 20 are slidably connected; the soundproof cover 201 is arranged around the outside of the roller 30; and one side of the cover 202 is rotatably connected to the soundproof cover 201.

[0034] Rotate the cover 202 so that it moves out from the end of the soundproof cover 201. At this time, the roll material is fitted onto the surface of the roller 30 inside the soundproof cover 20 from the end of the soundproof cover 20. Then rotate the cover 202 so that the other side fits into the soundproof cover 201, closing the end of the soundproof cover 201. Rotate the soundproof cover 201 so that the cover 202 and the soundproof cover 201 are connected by friction rotation, and the soundproof cover 201 rotates inside the groove 20, causing the soundproof cover 201 to drive the opening 203 to rotate, making it easy to adjust the position of the opening 203. The roll material is wound around the surface of the roll material through the opening 203. During the installation of the roll material, the soundproof cover 201 can absorb the noise generated during installation and reduce environmental noise.

[0035] This multi-axis integrated air expansion shaft facilitates the fixing of rolled materials. The specific implementation method is as follows:

[0036] The roller 30 has an inflatable structure, which includes: a groove 301 inside the roller 30, a chamber 401 installed on the inner wall of the groove 301, two sets of airbags 402 symmetrically arranged on the surface of the chamber 401, multiple locking blocks 403 symmetrically embedded at both ends of the roller 30, airbags 404 symmetrically connected to the surface of the chamber 401, a placement groove 405 symmetrically embedded on the surface of the roller 30, a pusher block 406 connected inside the placement groove 405, the end of the airbag 404 connected to the pusher block 406, a sliding connection between the roller 30 and the locking blocks 403, the locking blocks 403 having an arc-shaped structure, the end of the airbag 402 penetrating the surface of the roller 30 and connected to the locking blocks 403, the locking blocks 403 being embedded in the surface of the roller 30, the end of the airbag 404 being connected to the pusher block 406, and a sliding connection between the pusher block 406 and the placement groove 405.

[0037] When the roll material is installed on the surface of the roller 30, gas is introduced into the chamber 401. The gas then enters the airbag 402 and airbag 404 through the chamber 401, causing both airbags to inflate simultaneously. At this time, the end of airbag 402 pushes the locking block 403 outward, causing the locking block 403 to move outward inside the roller 30. The end of the locking block 403 moves to the top of both sides of the roll material, so that one side of the locking block 403 fits against both ends of the roll material, which can limit the movement of both sides of the roll material. At the same time, airbag 404 inflates, pushing the push block 406 outward, causing the end of the push block 406 to push out. The end of the push block 406 fits against the inner diameter of the roll material, supporting the roll material and fixing its position.

[0038] Working principle: When using this low-noise multi-axis integrated air shaft, a groove 20, a soundproof cover 201, a cover 202, and an opening 203 are provided. The soundproof cover 201 blocks the outside of the roller 30 to facilitate sound insulation. An airbag 404, a placement groove 405, and a push block 406 are provided. The airbag 402 fixes the two ends of the roll material, while the airbag 404 supports and fixes the roll material, increasing the overall practicality.

[0039] 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.
