Description

Technical Field

[0001] The utility model relates to the technical field of inflation equipment, in particular to an automatic inflation device for an inflatable bag. Background Art

[0002] Automatic air bag inflation equipment is a mechanical device designed to automatically inflate air bags. It is widely used in logistics, warehousing, transportation and other industries to protect goods from damage such as collisions and squeezing.

[0003] When operating existing air bag inflation equipment, it is usually necessary to first put the inflation port of the air bag on the inflation tube, and then drive the air bag to automatically move along the axial direction of the inflation tube through the rotation of the guide shaft and the rubber wheel, so as to achieve the purpose of automatic inflation. However, the existing inflation equipment lacks a mechanism that can detect whether the air bag is leaking. That is, after the inflation is completed, if the air bag is damaged and leaks, it is often difficult for the staff to discover it in time. When the damaged air bag is used to package goods, the air bag cannot play a good cushioning effect, and it is difficult to fully ensure the safety of the goods, which may cause the goods to be damaged due to collision, thereby affecting the quality of the product. Therefore, designing an inflation device that can automatically detect whether the air bag is leaking is a problem that needs to be solved urgently by those skilled in the art. To this end, we propose an automatic inflation device for air bags to effectively solve the above-mentioned drawbacks. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic inflation device for an inflatable bag, so as to solve the problems raised in the above-mentioned background technology.

[0005] The utility model is realized through the following technical solutions: an automatic inflation device for an inflatable bag, comprising a body, a discharge shaft and a guide shaft being rotatably provided on the body, an inflation guide mechanism being fixed on the body, a support plate being slidably provided on the body, a swing plate being rotatably provided on the body, the support plate being located below the swing plate, a counterweight being provided at one end of the top surface of the swing plate, a laser sensor being fixed on the body, and when the swing plate is kept in a horizontal state, the detection end of the laser sensor is aligned with the counterweight.

[0006] Optionally, an upper slider and a lower slider are slidably connected to the side wall of the machine body in the vertical direction, a rotating rod is fixed on the rocking plate, the rotating rod is rotatably connected to the upper slider, and the supporting plate is fixedly connected to the lower slider.

[0007] Optionally, a bidirectional screw is rotatably provided in the body, and the upper slider and the lower slider are both threadedly connected to the bidirectional screw. A strip opening is also provided on the body for the upper slider and the lower slider to pass through, and the top end of the bidirectional screw passes through the top wall of the body and is provided with a rotating handle.

[0008] Optionally, a torsion spring is sleeved on the outer side of the rotating rod, and both ends of the torsion spring are fixedly connected to the swing plate and the upper slider respectively; when the counterweight block is removed, the swing plate is in a horizontal state.

[0009] Optionally, both ends of the rocking plate are bent upward, and the length of the rocking plate is consistent with the sum of the lengths of the two sections of the inflatable bag.

[0010] Optionally, the top surface of the swing plate is provided with symmetrically distributed mounting columns, and the side of the counterweight block facing the swing plate is provided with mounting holes for inserting the mounting columns.

[0011] Compared with the prior art, the present invention provides an automatic inflation device for air bags, which has the following beneficial effects:

[0012] 1. This utility model utilizes a swing plate rotatably mounted on the machine body, which cooperates with a supporting plate below to enable the inflatable bag to be transported between the swing plate and the supporting plate. When the inflatable bag leaks, the tilt of the swing plate causes the counterweight on the top surface to tilt as well, causing the laser sensor to sense the change in the counterweight's position, thereby detecting the leak, emitting a warning signal, and stopping the device. This allows for immediate leak detection after inflation, improving the quality of the inflatable bag and ensuring the protection of the cargo.

[0013] 2. The utility model designs the swing plate and the supporting plate to be a structure that can be controlled by a bidirectional screw rod, so that the distance between the swing plate and the supporting plate can be adjusted, thereby being suitable for inflatable bags of more specifications and types.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1 - Figure 5 An automatic inflation device for an inflatable bag includes an organism 1, on which a discharge shaft 101 and a guide shaft 102 are rotatably provided, and an inflation guide mechanism 2 is fixedly provided, so that the inflatable bag can be guided by the guide shaft 102 and the inflation guide mechanism 2 when inflating, so that the inflatable bag can be automatically transported in an orderly manner, thereby achieving the purpose of automatic inflation.

[0022] Furthermore, a support plate 3 is slidingly provided on the body 1, and a swing plate 4 is rotatably provided on the body 1. The support plate 3 is located below the swing plate 4 so that the inflatable bag can pass between the support plate 3 and the swing plate 4 and always remain level during transportation. Specifically, when the inflatable bag is in an inflated state, the upper and lower ends of the inflatable bag are respectively in contact with the swing plate 4 and the support plate 3.

[0023] To detect air leaks in the airbag after inflation, the present application includes a counterweight 5 at one end of the top surface of the rocking plate 4. Specifically, in this embodiment, the counterweight 5 is located on the side of the rocking plate 4 near the inflation guide mechanism 2, allowing the counterweight 5 to tilt to one side. A laser sensor 6 is fixed to the body 1 and electrically connected to the control unit so that the laser sensor 6 can transmit a signal to the control unit. When the rocking plate 4 remains horizontal, the detection end of the laser sensor 6 is aligned with the counterweight 5, ensuring that the device does not issue an air leak warning when the rocking plate 4 is horizontal.

[0024] The following is a detailed description of the rocking plate 4, the counterweight 5 and the laser sensor 6 to make the process of air leakage detection clearer: The two ends of the rocking plate 4 are bent upward, and the length of the rocking plate 4 is equivalent to the sum of the lengths of the two sections of the inflatable bag, so that the inflatable bag can be smoother when passing the side of the rocking plate 4, reducing the obstruction to the movement of the inflatable bag. The top surface of the rocking plate 4 is provided with symmetrically distributed mounting posts 403, and the side of the counterweight 5 facing the rocking plate 4 is provided with mounting holes 501 for inserting the mounting posts 403. Specifically in this embodiment, the counterweight 5 is installed on the side of the rocking plate 4 close to the inflation guide mechanism 2. The counterweight 5 is detachable so that the user can use counterweights 5 of different specifications, so that the counterweight 5 can always face the detection end of the laser sensor 6 when the inflatable bag is not leaking; and when the inflatable bag is leaking, the counterweight 5 will tilt downward, such as Figure 3 As shown, the laser sensor 6 senses the change in the position of the counterweight 5, causing the device to issue an alarm and stop running, making it convenient for the staff to remove the leaking inflatable bag and ensuring the quality of the inflatable bag.

[0025] In order to make the device applicable to air leakage detection of more specifications and types of inflatable bags, the present application has an upper slider 7 and a lower slider 701 slidingly connected in the vertical direction on the side wall of the body 1, and a rotating rod 401 is fixedly provided on the rocking plate 4, and the rotating rod 401 is rotatably connected to the upper slider 7, and the supporting plate 3 is fixedly connected to the lower slider 7, so that the sliding of the upper slider 7 and the lower slider 701 can drive the rocking plate 4 and the supporting plate 3 to rise and fall, thereby changing the distance between the rocking plate 4 and the supporting plate 3 to be applicable to air leakage detection of more specifications of inflatable bags.

[0026] Specifically, a bidirectional screw 8 is rotatably mounted within the housing 1 . Both the upper and lower sliders 701 are threadedly connected to the screw 8 , enabling the screw 8 to control the relative movement of the upper and lower sliders 701 , thereby controlling the relative elevation of the rocking plate 4 and the support plate 3 . The housing 1 also includes a slot 103 through which the upper and lower sliders 701 pass. Both the upper and lower sliders 701 slidably engage with the slot 103 . The top end of the screw 8 extends through the top wall of the housing 1 and is provided with a rotating handle 801 , allowing the user to manually adjust the distance between the rocking plate 4 and the support plate 3 , making operation simple and convenient.

[0027] The swing plate 4 is further optimized, and a torsion spring 402 is provided on the outside of the rotating rod 401, and the two ends of the torsion spring 402 are respectively fixedly connected to the swing plate 4 and the upper slider 7; when the counterweight 5 is removed, the swing plate 4 is in a horizontal state, so that the staff can directly take off the counterweight 5 after removing the leaking inflatable bag. At this time, the torsion spring 402 will reset the swing plate 4 to a horizontal state and start the device again, so that the inflatable bag can pass smoothly between the support plate 3 and the swing plate 4.

[0028] The working principle and usage process of the present invention are as follows: first, the uninflated inflatable bag is put on the discharge shaft 101, and then the free end of the inflatable bag is pulled out and made to pass around the guide shaft 102 so that the inflatable bag enters the inflatable guide mechanism 2. As the device is started, the inflatable bag is transported to the outside of the inflatable guide mechanism 2 after being inflated. At this time, the swing plate 4 is in a horizontal state, and the lower surface of the swing plate 4 is in contact with the inflatable bag. Then, the counterweight 5 is installed on the mounting column 403 on the side of the swing plate 4 close to the inflatable guide mechanism 2, so that the detection end of the laser sensor 6 is aligned with the position of the counterweight 5.

[0029] When one of the inflatable bags leaks, the thickness of the leaking inflatable bag is smaller than that of the non-leaking inflatable bag. Therefore, when the leaking inflatable bag reaches the bottom of the counterweight 5, the counterweight 5 will drive the rocking plate 4 downward and start to tilt. At this time, the height of the counterweight 5 will decrease, and the detection end of the laser sensor 6 will detect that the counterweight 5 is not in its original position, and then send a signal to the control unit. The control device will issue an alarm and stop the operation of the device. At this time, the staff will know that the inflatable bag is leaking, and then remove the leaking inflatable bag and the counterweight 5. The rocking plate 4 will return to the horizontal state due to the action of the torsion spring 402, and the device can be started again, the counterweight 5 can be placed and the detection can be carried out according to the above steps.

[0030] When it is necessary to test inflatable bags of different specifications, the handle 801 can be turned to drive the bidirectional screw 8 to rotate, so that the upper slider 7 and the lower slider 701 start to move relative to each other, and then the support plate 3 and the rocking plate 4 are relatively raised and lowered, and the distance between the support plate 3 and the rocking plate 4 is adjusted so that the upper and lower ends of the inflatable bag are always in contact with the rocking plate 4 and the support plate 3. Finally, counterweights 5 of different heights are used according to the height of the rocking plate 4 so that the rocking plate 4 is in a horizontal state, and the detection end of the laser sensor 6 can always be aligned with the counterweight 5. Then the device is started again. According to the above detection steps, the inflatable bag can be detected to see if it is leaking, thereby ensuring the quality of the inflatable bag and avoiding damage to the subsequently packaged goods.
