Description

Technical Field

[0001] This invention relates to the field of micro-airbag production technology, specifically to a micro-airbag, an apparatus for producing micro-airbags, and a method for producing micro-airbags. Background Technology

[0002] Micro-airbags are capsules filled with compressed air or water. They utilize the compressibility of air and the fluidity of water to achieve elasticity. Because of their excellent cushioning performance, micro-airbags are widely used in various shock-absorbing devices and are an essential shockproof facility for transporting precision instruments. In daily production and life, some equipment requires the use of multiple micro-airbags at the same time.

[0003] For example, invention patent CN100556676C discloses a method for processing micro-inflatable bags. Two interlocking, figure-eight-shaped silicone sheets are bonded to the spherical part of an inner liner mold using a cold-setting adhesive. The contact area between the two silicone sheets is coated with a thermosetting adhesive. The spherical part of the inner liner mold is composed of alloy strips made of shape memory alloy. These alloy strips are spherical at room temperature and deform into elongated strips upon heating. The silicone sheets and the inner liner mold are heated as a whole. When the overall temperature rises to the temperature required for the thermosetting adhesive to bond, the alloy strips undergo shape memory deformation, causing the inner liner mold to become strip-shaped. The inner liner mold can then be removed from the round hole at the top of the micro-inflatable bag. After the inner liner mold is removed, a heated silicone block is used to seal the round hole at the top of the micro-inflatable bag, thus creating the finished micro-inflatable bag.

[0004] However, the device cannot directly produce micro-inflatable bodies, resulting in low production efficiency. Furthermore, when producing micro-inflatable bodies, the device requires manual feeding pliers to place the colloid into a mold, and then inserting an air needle into the colloid inside the mold to blow air into the colloid to form micro-inflatable bodies. This method requires manual operation and is complex. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a micro-airbag, an apparatus for producing micro-airbags, and a method for doing so, thus solving the technical problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a micro-airbag body, wherein the micro-airbag body is composed of several micro-airbags bonded together, and the air chambers in the several micro-airbags have different volumes.

[0007] An apparatus for producing micro-inflatable bladders includes a blow-off needle body composed of a plurality of rubber needles arranged in a row. Each rubber needle has an air needle at its center. The outer diameter of the air needle is smaller than the inner diameter of the rubber needle. The inner diameter of the rubber needle and the outer diameter of the air needle form a cavity for the flow of heated colloid. The discharge end of the rubber needle is constricted inward. The discharge end port of the rubber needle is a rubber needle hole. The exhaust end port of the air needle is an air needle hole. The discharge end of the blow-off needle body is provided with a mold. The plurality of rubber needles are connected to a colloid output control system, and the plurality of air needles are connected to a gas output control system.

[0008] Preferably, the colloid output control system includes: a colloid flow control component and a colloid output device, wherein a plurality of colloid needles are simultaneously or separately connected to the colloid output device through the colloid flow control component; the gas output control system includes: a gas flow control component and a gas output device, wherein a plurality of gas needles are simultaneously or separately connected to the gas output device through the gas flow control component.

[0009] Preferably, one side of the mold is connected to a device for forming the micro-airbag.

[0010] Preferably, when the output time interval of the colloid output control system is the same, the distance between the inner diameter of the colloid needle and the outer diameter of the air needle determines the thickness of the capsule, and the inner diameter of the colloid needle and the thickness of the capsule are positively correlated.

[0011] Preferably, when the inner diameter of each glue needle is the same, the glue supply time of the hot glue output system determines the volume of the micro airbag, and the output time of the hot glue output system is positively correlated with the volume of the micro airbag.

[0012] Preferably, when the output time intervals of the gas output control system are the same, the inner diameter of the gas needle determines the volume of the gas chamber, and the inner diameter of the gas needle and the volume of the gas chamber are positively correlated.

[0013] Preferably, by controlling the gas output device, the output gas is made to be uninterrupted, uniformly intermittent, and regularly intermittent, forming gas cavities of different shapes.

[0014] This invention also protects a production method using the above-described apparatus, comprising the following steps: S1: Inject hot colloid into the glue needle, start the colloid output control system, and control the colloid output device to continuously and evenly output hot colloid into the glue needle, so that the hot colloid is output from the glue needle. S2: Inject gas into the hot glue body extruded from the glue needle hole, start the gas output control system, control the gas output device to deliver gas to the air needle, and inject the gas into the hot glue body discharged from the glue needle hole through the air needle, so that an air cavity is formed in the hot glue body, forming a micro air bladder. S3: When combining multiple glue needles, select molds of different shapes as needed and set the molds at the glue outlets of multiple glue needles. The hot glue filled with gas is injected into the mold. Due to the adhesiveness of the airbag glue, multiple micro airbags can be bonded together in the mold to form a micro airbag body, and finally form a mold-shaped micro airbag body. S4: Stop injecting hot colloid and stop filling with gas. First, control the gas output device to stop outputting gas, and then control the colloid output device to stop outputting colloid. S5: Molding, start the molding equipment to fix and shape the micro-airbag.

[0015] Beneficial effects This invention provides a micro-inflatable bladder, an apparatus for producing micro-inflatable bladders, and a method thereof, which have the following beneficial effects: 1. When multiple micro-airbags are needed simultaneously in production and daily life to achieve shock absorption and cushioning requirements, this device can directly produce micro-airbags, improving work efficiency.

[0016] 2. The device is equipped with a glue needle, which allows the hot colloid to flow inside the glue needle. The device is also equipped with an air needle, which facilitates the flow of gas inside the air needle. The hot colloid discharged through the glue needle can accumulate at the end of the glue needle. By introducing gas into the hot colloid accumulated at the end of the glue needle through the air needle, a cavity can be formed. There is no need to manually clamp the colloid, making the operation simple. 3. By setting up a colloid output device, hot colloid can be continuously input into the colloid needle. The colloid flow control component can control the colloid output device to control the amount of colloid supplied. By setting up a gas output device, gas can be continuously input into the gas needle. The gas flow control component can control the gas output device to control the amount of gas output. This enables continuous production of micro-airbags, which facilitates the production of micro-airbag bodies and has high production efficiency. Attached Figure Description

[0032] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.

[0033] The working principle and usage process of this invention are as follows: When producing a single micro-airbag 6, the colloid control flow component is turned on, allowing the colloid output device to input hot colloid into the colloid needle 1. The hot colloid after entering the colloid needle 1 is discharged from the colloid needle hole 5, and the discharged hot colloid accumulates at the colloid needle hole 5. The gas control flow component is turned on, allowing the gas output device to input gas into the gas needle 2. The gas after entering the gas needle 2 is discharged through the gas needle hole 4 into the hot colloid accumulated at the colloid needle hole 5. The gas output device is turned off, and the gas filling into the hot colloid is stopped. At this time, an air cavity 62 is formed inside the hot colloid. The colloid output device is controlled to continue outputting a portion of hot colloid and then turned off. At this time, the air cavity 62 can be sealed, thereby forming a single micro-airbag 6. In the production of micro-airbag 7, multiple glue needles are combined, and the required mold 8 is installed on the glue needle near the glue needle hole 5. The glue flow control component is turned on, so that the glue output device inputs hot glue into the glue needle. The gas flow control component is turned on, so that the gas output device inputs gas into the gas needle. The hot glue after entering the glue needle is discharged from the glue needle hole 5. The discharged hot glue will accumulate at the glue needle hole 5. The gas after entering the gas needle is discharged through the gas needle hole 4 into the hot glue accumulated at the glue needle hole 5. The gas output device is turned off, and the gas filling into the hot glue is stopped. At this time, an air cavity 62 is formed inside the hot glue. The glue output device is controlled to continue to output a part of the hot glue and then turned off. At this time, the air cavity 62 can be sealed. The molding device is turned on to form a layer of micro-airbag 6. The above steps are repeated until the formed micro-airbags 6 adhere to each other and fill the interior of the mold 8. After all the micro-airbags 6 inside the mold 8 are adhered to each other and remain elastic, they are demolded to form micro-airbag 7.

[0034] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
