Manufacturers generally provide a plurality of reinforcing ribs on the outer wall of the vacuum storage box to improve the strength of the side wall of the whole vacuum storage box in order to solve the problems.
At present, if the reinforcing ribs are directly and simultaneously molded in the injection molding stage of the vacuum storage box, the requirement on the injection mold is quite high, because the bottom of the vacuum storage box is smaller than one end with the opposite opening, the vacuum storage box is not a regular plane, if the reinforcing ribs are simultaneously molded on the outer wall of the vacuum storage box, the mold opening structure of the injection mold used in the later mold opening is more complex, more line structures or other interlocking structures are needed to realize the mold opening, and besides the manufacturing and maintenance cost of the injection mold is increased, the mold opening of the later vacuum storage box is not facilitated.

Referring to fig. 1 to 5, in order to implement the carrying of the opening mechanism 330 and the vacuum storage box clamped by the opening mechanism thereon, and in particular, the reciprocating carrying between the working area of the automatic screw driving machine 200 and the assembly conveyor line 100, in one embodiment of the present application, the moving mechanism 310 includes a frame 311, a sliding table 312, and a lifting rod 313 vertically slidably mounted on the sliding table 312; a first sliding rail 318 is arranged on the top of the frame 311, the sliding table 312 is slidably mounted on the first sliding rail 318, a first rack 314 is arranged on one side of the first sliding rail 318 in parallel, and a first driving motor 315 for matching with the first rack 314 is arranged on the sliding table 312; a second driving motor 316 is arranged on the sliding table 312, a second rack bar 317 is arranged on the lifting rod 313, and the second driving motor 316 can cooperate with the second rack bar 317 to drive the lifting rod 313 to lift on the sliding table 312; the rotation mechanism 320 is installed at the lower end of the elevating rod 313.
The frame 311 and the first sliding rail 318 are actually installed above the working area of the assembly line 100 and the automatic screw driving machine 200, so that the sliding table 312 drives the opening mechanism 330 to realize the transfer between the two devices. In addition, the lifting rod 313 can drive the stretching mechanism 330 to adjust different heights, so that the stretching mechanism 330 and a vacuum storage box thereon are not interfered with the external equipment in the transferring process. Of course, in some embodiments, the vacuum storage box can also meet the transfer requirements of vacuum storage boxes of different specification types. The main purpose of the rotation mechanism 320 is to facilitate turning over the different sides of the vacuum storage box, so that the automatic screw driving machine 200 and the reinforcing bar mounting device 400 can realize screw driving fixation on the different sides of the vacuum storage box.
Referring further to fig. 3 and 4, in order to better realize that different sides of the vacuum storage case can be operated by the automatic screw driving machine 200 and the reinforcing rib mounting device 400, in one embodiment of the present application, the rotating mechanism 320 includes a fixing base 321, a speed reducer 322 mounted on the fixing base 321, and a third driving motor 323 connected with the speed reducer 322, a rotating main shaft 324 is rotatably disposed on the fixing base 321, an outer gear ring 325 is disposed on an outer wall of the rotating main shaft 324, an output end of the speed reducer 322 is engaged with the outer gear ring 325 through a driving gear 326, and the rotating main shaft 324 is connected with the opening mechanism 330. Wherein, the outer gear ring 325 and the driving gear 326 are matched, so that the whole opening mechanism 330 can be spatially screwed; to enable the entire distracting mechanism 330 to be stopped at a specific angle for the automated screw machine 200 and the stiffener attachment 400 to operate. It should be noted that, because the opening mechanism 330 and the vacuum storage box clamped thereon are not uniform, the opening mechanism 330 is easy to be unstable and vibrate strongly when rotating around the rotating main shaft 324, and therefore, the application itself uses the cooperation of the outer gear ring 325 and the driving gear 326, so that the vibration brought by the opening mechanism 330 in the rotating process can be reduced to a certain extent to directly impact the third driving motor 323, and the third driving motor 323 can be effectively protected. Further, in the embodiment of the present application, the third driving motor 323 is a servo motor, which facilitates control of the rotation speed and the rotation angle.
Referring to fig. 1 to 4, in order to better prop open the vacuum storage compartment while achieving stable handling in the present application, in one embodiment of the present application, the prop-open mechanism 330 includes a rotating base 331, a body sliding rail 332 disposed on the rotating base 331, and two pushing bases 333 slidably mounted on the body sliding rail 332, the rotating base 331 being mounted on a rotating end of the rotating mechanism 320; the rotating seat 331 is provided with two pushing cylinders 334, each pushing cylinder 334 is connected with the pushing seat 333 on the corresponding side, and the output ends of the two pushing cylinders 334 are arranged back to back and can push the two pushing seats 333 to move on the main body sliding rail 332 in opposite directions or back to back. When the two pushing seats 333 move in opposite directions, at this time, one end of the extending ends of the two pushing seats are outwards inserted into the opening of the vacuum storage box, and when the two pushing seats 333 move in opposite directions, the distance between the two pushing seats 333 can be enlarged, the inner walls of the two opposite sides of the vacuum storage box can be simultaneously propped against in opposite directions, so that the clamping and supporting stability of the whole vacuum storage box can be ensured, and the vacuum storage box is convenient to carry and install and fix the reinforcing ribs.
In the above embodiment, two pushing cylinders 334 are used to connect to the same air supply system together, so that synchronous movement can be realized to realize the action of extending into and expanding the vacuum storage box; the structure principle is simple and the control is convenient. In addition, when the two pushing seats 333 push the inner walls of the two sides opposite to the vacuum storage box, the whole vacuum storage box is actually supported.
In the above embodiment, the two pushing cylinders 334 are used to respectively and independently push the pushing seats 333 to move in opposite directions or in opposite directions to realize the function of clamping the vacuum storage box, and the design of pushing the pushing cylinders 334 makes the opening mechanism 330 in the above embodiment only suitable for opening the vacuum packaging box with a specific specification and size, and the main reason is that the pushing cylinders 334 can only stop at the minimum extending amount and the maximum extending amount, but can not stop the extending amount at any position, so that the two pushing seats 333 cooperate to only open the vacuum packaging box with a specific specification and size. With further reference to fig. 5-8, in another embodiment of the present application, the spreading mechanism 330 includes a rotating base 331, a lever 335 rotatably mounted on the rotating base 331, two sets of link assemblies 336, and pushing bases 333 positionally adjustably hinged on both ends of the rotating base 331; the lengths of the two groups of connecting rod assemblies 336 can be adjusted, and the rotating seat 331 is installed on the rotating end of the rotating mechanism 320; two ends of the lever 335 are respectively hinged to one end of a group of connecting rod assemblies 336, and the other end of each group of connecting rod assemblies 336 is hinged to the pushing seat 333 on the corresponding side; the rotating seat 331 is provided with a rotating motor 337, the rotating motor 337 can drive the lever 335 to swing around the rotation center thereof, and two ends of the lever 335 can synchronously push the pushing seat 333 to swing around the rotating seat 331 through the connecting rod assembly 336 on the corresponding side so as to realize opposite opening or closing of the outward ends of the two pushing seats 333. It should be noted that, the rotating motor 337 is a servo motor, and the rotation angle of the servo motor can be adjusted, so that the lever 335 can be controlled to rotate around the rotation center by a specific angle, and the outward swinging angle of the pushing seats 333 can be adjusted by the connecting rod assembly 336, so that the vacuum storage box can adapt to vacuum storage boxes with different specifications and sizes. Meanwhile, as the rotary motor 337 is adopted for driving, no additional pneumatic pipeline is required to be arranged in the actual use process, and the manufacturing cost and the later maintenance cost of the whole equipment are reduced.
With further reference to fig. 8, it should be noted that, since the outward swinging angle of the pushing bases 333 can be adjusted, the outward ends of the two pushing bases 333 should have specific portions to adapt to the inner wall dimensions of the vacuum storage box under different dimensions. For this purpose, in a modified embodiment of the present application, the pushing base 333 includes a plurality of supporting blocks 33b, the supporting blocks 33b are hinged in sequence by shaft pins 33c, and the supporting blocks 33b at either end are adjustably mounted on the rotating base 331; the pivot pin 33c is provided with a coil spring 33d, and the coil spring 33d can force the adjacent two support blocks 33b to be kept in a straight shape. When the two pushing seats 333 swing to be perpendicular to the rotating seat 331, the distance is the minimum effective spreading distance of the whole spreading mechanism 330; if the pushing bases 333 continue to swing outwards, the outward ends of the two pushing bases 333 will gradually get away, and the two pushing bases 333 are in a horn shape, but because different supporting blocks 33b are hinged, a coil spring 33d is also present, so that the supporting block 33b located inside the vacuum storage box can be forced to swing around the supporting block 33b located outside the opening of the vacuum storage box by a certain angle, so that the supporting block 33b located inside the vacuum storage box is attached to the inner wall of the vacuum storage box, and the design can make the two opposite inner walls of the vacuum storage box be pushed and abutted by the partial areas of the two pushing bases 333 respectively at the maximum degree, so as to realize the opening effect.
It should be noted that, the minimum effective propping distance is understood in the present application that at least a part of the outward end of the pushing seats 333 is capable of completely fitting the space between the two pushing seats 333 when the inner wall of the vacuum storage box needs to be installed with the reinforcing rib area, so as to ensure that the two pushing seats 333 can effectively and uniformly abut against the two opposite inner walls of the vacuum storage box. In addition, the design that the supporting blocks 33b at either end can be adjustably mounted on the rotating base 331 can facilitate the adjustment of the minimum effective spreading distance between the two pushing bases 333 by the operator. In this embodiment, the length of the two sets of link assemblies 336 can be adjusted to fit the minimum effective distraction distance between the pushing seats 333.
