When the material storage platform works normally, a large quantity of bolts to be packaged are stored in the material storage platform 1; a worker pulls the bolt to fall into the dumping hopper 32, and the bottom of the dumping hopper 32 is pressed on the electronic scale 22, so that the weighing of the bolt is realized; when the weight reaches a preset value, the worker controls the rotating cylinder 33 to drive the dumping hopper 32 to rotate until one side of the dumping hopper 32 abuts against the connecting hopper 42, so that the bolts are poured into the vertical pipeline 41, and the bolts poured into the vertical pipeline 41 fall downwards under the action of gravity until the bolts fall out from the bottom end of the vertical pipeline 41; in synchronization with the above process, the film supply roller 52 stores the packaging film for preparing the packaging bag, the traction roller group 53 is driven by the traction motor 54 to tear out the packaging film with a predetermined length, and the packaging film is wrapped in the vertical pipe 41 in a columnar shape under the compression of the plurality of H-shaped wheels 55; the packaging film intermittently advances along the vertical pipeline 41, the vertical sealing mechanism completes the fixation of two sides, the transverse sealing and cutting mechanism completes the fixation of the bag bottom and the bag top, and cuts off the adjacent packaging bags, wherein the power for the intermittent advancement of the packaging film along the vertical pipeline 41 comes from the gravity of the bolts falling into the packaging bags; a bag of packaged and cut bolts which lack upward pulling force fall downwards and fall on the blanking conveyer belt 7, so that the packaged bolts are conveyed to a preset position by the blanking conveyer belt 7; to sum up, this application only needs one workman, can accomplish a plurality of workman's bolt packing task, effectively reduces labour cost.

This application needs the gravity of make full use of bolt, and consequently the initial height of bolt has certain requirement, nevertheless emptys the bolt in the eminence, then has the inconvenient problem of unloading, for this reason as shown in fig. 2, scissor lift 11 is installed to storage platform 1 bottom to utilize scissor lift 11 to control storage platform 1 and go up and down, and then facilitate in storage platform 1 for the bolt of falling the material, and ensure that the high cooperation requirement that highly satisfies of storage platform 1 when normal work.

The reason why the worker needs to dial the material in the material pouring hopper 32 is that potential energy exists when the bolt falls, so that the numerical value jumps when weighing, and therefore the full-automatic equipment cannot be adopted for weighing, and in order to facilitate the worker to dial the material bolt, as shown in fig. 2, one end of the material storage table 1 is provided with the swing sliding plate 12, the other end of the material storage table is provided with the vibration motor 13, the vibration motor 13 is additionally arranged on the material storage table 1, and the bolt stacked on the material storage table 1 is pushed to the swing sliding plate 12 by using the vibration force generated by the vibration motor, so that the worker can dial the material nearby, and the convenience; the material storage table 1 is rotatably provided with a rotating shaft 14, the swinging sliding plate 12 is fixed on the rotating shaft 14, and the material storage table 1 is provided with a swinging motor 15 for driving the rotating shaft 14; when a worker needs to dial a bolt into the pouring hopper 32 for weighing, the swing motor 15 drives the rotating shaft 14 to rotate, so that the swing sliding plate 12 is driven to incline towards the pouring hopper 32, and the swing sliding plate 12 provides an inclined slideway for guiding the bolt to fall into the pouring hopper 32; when the pouring hopper 32 needs to pour the weighed bolt into the filling pipeline, the swing motor 15 drives the rotating shaft 14 to rotate, so as to drive the swing sliding plate 12 to stick up and return, on one hand, the swing sliding plate 12 is prevented from interfering the material pouring process of the pouring hopper 32, and on the other hand, the swing sliding plate 12 blocks the bolt, so that the bolt is prevented from falling out of the storage table 1.

In practical use, it is found that the weighing time is far longer than the filling time, so that the practical packaging efficiency is affected, and for this purpose, as shown in fig. 2, the storage table 1 is provided with two swing sliding plates 12 in parallel; the weighing platform 21 is provided with two electronic scales 22 corresponding to the two swing sliding plates 12; the number of the material pouring mechanisms is two, and the material pouring mechanisms correspond to the two electronic scales 22; thereby realize accomplishing the technical effect of weighing and for the filling pipeline feed in turn by two hopper 32, effectively improve the work efficiency of this application.

It should be noted that, as shown in fig. 2, a connecting sleeve 24 is fixed at an output end of the rotating cylinder 33, and a connecting groove 25 for slidably connecting the connecting sleeve 24 is formed in an outer wall of the dumping hopper 32, so that the rotating cylinder 33 is used to directly drive the connecting sleeve 24 to rotate, the dumping hopper 32 is driven in the rotating process of the connecting sleeve 24, and the dumping and resetting processes of the dumping hopper 32 are completed; the connecting groove 25 and the connecting sleeve 24 have width allowance, when the dumping hopper 32 is placed on the electronic scale 22, the connecting sleeve 24 and the two side groove walls of the connecting groove 25 are not in contact, so that the problem that the weighing precision is influenced due to the fact that the connecting sleeve 24 generates downward pressure or upward tension on the dumping hopper 32 is solved.

To ensure that the bolts are smoothly poured into the connecting hopper 42, as shown in fig. 2, the extension sliding plate 34 is integrally formed on the side of the dumping hopper 32 close to the connecting hopper 42, and the bolts in the dumping hopper 32 are smoothly poured into the connecting hopper 42 by optimizing the structure of the dumping hopper 32.

It should be noted that, as shown in fig. 3, a plurality of through holes 43 are formed through the pipe wall of the vertical pipe 41, so that on one hand, the sound wave diffusion capability in the vertical pipe 41 is improved, and the noise accumulation is reduced, and on the other hand, the air circulation performance is ensured, and the situation that the packaging bag cannot be fully unfolded due to the negative pressure generated in the packaging bag is avoided.

In practical application, it is found that when the bolt falls into the packaging bag through the vertical pipe 41, the packaging bag may be damaged due to an excessive impact force, for this reason, two inclined plates 44 are welded and fixed inside the bottom end of the vertical pipe 41, and the two inclined plates 44 are arranged in a staggered manner, so that the falling bolt is decelerated by the inclined plates 44, and the hidden danger that the bolt damages the packaging bag is reduced.
