DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.
[0022] Refer to Figures 1-4 The film valve inflatable bag strength detection equipment with buffer protection structure is described. The equipment is mainly composed of two main parts of base 1 and mounting rack 5, and each part cooperates to realize the strength detection of the film valve inflatable bag.
[0023] The upper end surface of the base 1 is provided with the placing table 2 for placing the film valve inflatable bag to be detected. It is worth noting that the surface of the placing table 2 is provided with anti-skid lines, which can effectively increase the friction between the inflatable bag and the placing table 2, so as to ensure that the inflatable bag will not slide randomly during the detection process, thereby ensuring the accuracy of the detection result.
[0024] The base 1 is internally provided with the movable chamber 12, and the inner screw 13 is rotatably installed in the movable chamber 12. The lifting frame 14 is threadedly sleeved on the inner screw 13. At the same time, the upper end surface of the placing table 2 is provided with the lifting opening 3, the lifting opening 3 is communicated with the movable chamber 12, and the protective plate 4 connected with the lifting frame 14 is installed in the lifting opening 3. The protective plate 4 is in the shape of an incomplete ring, and the gap is specially designed for the descending of the rectangular plate part of the pressing device 9. When the inner screw 13 rotates, the lifting frame 14 moves up and down along the inner screw 13, thereby driving the protective plate 4 to rise and fall in the lifting opening 3. When not detecting, the protective plate 4 is at the low position to prevent accidental collision, etc.; and when detecting, the protective plate 4 can be raised to the appropriate position to prevent the film valve inflatable bag from exploding and causing harm to the surrounding operators. In addition, the outer wall of the base 1 is provided with the communication opening 19, the communication opening 19 is communicated with the movable chamber 12 and corresponds to the synchronous belt 18, which provides convenience for the installation and maintenance of the synchronous belt 18.
[0025] The driving motor 7 is installed on the mounting rack 5, the driving motor 7 is connected with the outer screw 6, and the rotation of the driving motor 7 can drive the outer screw 6 to rotate. The nut 8 is threadedly sleeved on the outer screw 6, and when the outer screw 6 rotates, the nut 8 moves up and down along the axial direction of the outer screw 6. The mounting rack 5 is also provided with the dismounting opening 10, which is designed to facilitate the installation and dismounting of the pressing device 9.
[0026] The pressing device 9 is composed of a rectangular plate and a circular metal block. The rectangular plate is flexibly installed with the nut 8 through a plug-in mechanism. The plug-in mechanism comprises a plug 15 arranged on the nut 8 and a corresponding slot 16 arranged on the contact surface of the pressing device 9 and the nut 8. Through the cooperation of the plug 15 and the slot 16, the pressing device 9 can be conveniently installed on the nut 8, and can be easily separated when disassembled, facilitating the maintenance of the equipment and the replacement of the pressing device 9 of different specifications.
[0027] The circular metal block of the pressing device 9 can perform the pressing operation on the air bag of the film valve on the placing table 2 during the descending process. Moreover, a dismounting block 11 corresponding to the dismounting opening 10 is arranged on the outer wall of the pressing device 9, and when it is necessary to remove the pressing device 9 from the mounting frame 5, the pressing device 9 can be smoothly removed through the dismounting opening 10 by using the dismounting block 11. A pressure sensor (not shown in the figure) is arranged on the pressing device 9 according to the prior art, and during the pressing process of the air bag by the circular metal block, the pressure sensor can measure the pressure applied to the air bag by the circular metal block in real time, so as to realize the detection of the strength of the air bag of the film valve.
[0028] The outer screw 6 is connected with the inner screw 13 through a rotating mechanism, and the rotating mechanism comprises two synchronous wheels 17 arranged on the outer screw 6 and the inner screw 13. The two synchronous wheels 17 are connected through a synchronous belt 18. When the driving motor 7 drives the outer screw 6 (as shown in the figure, only the upper half of the outer wall of the outer screw 6 is provided with a thread) to rotate, the synchronous wheel 17 on the outer screw 6 also rotates, and through the transmission of the synchronous belt 18, the synchronous wheel 17 on the inner screw 13 also rotates, thereby driving the inner screw 13 to rotate. Such a design can ensure that the rotation of the outer screw 6 and the inner screw 13 is synchronous, so that the pressing action of the pressing device 9 and the lifting action of the protective plate 4 can be coordinated.
[0029] For example, when the pressing device 9 descends to detect the air bag, the protective plate 4 can be lifted synchronously for protection; and when the detection is completed and the pressing device 9 rises, the protective plate 4 will descend to hide and avoid hindering the operator.
[0030] When the utility model is used, the film valve air bag to be detected is placed on the placing table 2, and then the driving motor 7 on the mounting frame 5 is started to drive the outer screw 6 connected thereto to rotate. The nut 8 provided with the thread sleeve will descend due to the rotation of the outer screw 6 (when the pressing device 9 is installed on the nut 8, the rectangular plate part of the pressing device 9 will not rotate with the outer screw 6 due to the limitation of the inner space of the mounting frame 5 and the nut 8), and the nut 8 drives the pressing device 9 to descend, and the circular metal block thereof presses the film valve air bag placed on the placing table 2 on the base 1. The pressure sensor on the pressing device 9 measures the pressure applied to the air bag by the circular metal block in real time according to the prior art, so as to realize the detection of the strength of the air bag of the film valve.
[0031] When the outer screw rod 6 rotates, the inner screw rod 13 is also driven to rotate by the synchronous wheel 17 and the synchronous belt 18. When the inner screw rod 13 rotates, the lifting frame 14 sleeved with threads moves upward along the inner screw rod 13 (the protection plate 4 cannot be separated from the lifting opening 3 no matter how it moves, so it is limited and cannot rotate with the inner screw rod 13 together with the lifting frame 14), that is, when the pressing device 9 is detected to descend, the protection plate 4 rises, thereby providing protection.
[0032] In the scheme, when the pressing device 9 and the nut 8 and other components continue to rise and reach the highest position, the dismounting block 11 and the dismounting opening 10 have the same horizontal height, at this time, the pressing device 9 is directly horizontally moved, that is, the plug block 15 and the plug groove 16 are separated, and then the dismounting of the pressing device 9 is completed, thereby facilitating the maintenance, replacement or the like.
[0033] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
