The air current that air cock 411 was blown can upwards blow the portion of sealing of envelope like this for there is the gap between portion of sealing and the envelope body, and convenient subsequent opening of sealing. The guide plate 42 has a flat plate portion 421 inclined and a folded portion 422 inclined upward from a side of the flat plate portion 421, and a first flared inclined portion 423 is provided at an end of the flat plate portion 421 close to the air blowing mechanism 41. In this embodiment, the folding portion 422 is inclined upward and rearward, and the first flared inclined portion 423 is inclined downward and rearward from the upper left. The envelope body is pressed into the flat plate portion 421 by the first flaring slope portion 423. The pressing piece 43 is inclined downward in the machine direction from above the hem 422.

By sucking and transporting the letter from the hopper to the letter transfer mechanism 52. It should be understood that the letter transfer mechanism 52 is implemented by using a known pallet transfer belt, i.e., a card slot for placing a letter is formed on the pallet transfer belt, which is driven by a motor. At the front end of the letter transfer means 52 there is a letter acceleration means 53, which letter acceleration means 53 is arranged to accelerate the letter at the front end of the letter transfer means 52 such that the speed of the letter is greater than the transfer speed of the letter transfer means 52. This enables letter ejection to be effected at the front end of the letter transfer mechanism 52. It will also be appreciated that above the first conveyor 1 there is a suction mechanism 57, the suction mechanism 57 being located on the front side of the letter transfer mechanism 52 and serving to suck up the upper part of the envelope body so that the opening of the envelope body is opened to allow the envelope to form a cavity. The cavity is opposed to the front end of the letter transfer mechanism 52 so that the letter ejected at the acceleration of the letter acceleration mechanism 53 is thrown into the cavity of the envelope, thus achieving the bag-filling operation of the letter. It should be understood that the adsorption mechanism 57 may be implemented using known techniques. For example, the method is implemented by providing an air cylinder 571 and an adsorption component, the adsorption component comprises a plurality of suction nozzles 572 and a vacuum pump (not shown in the figure) communicated with the plurality of suction nozzles 572, the air cylinder 571 is vertically arranged above the first transmission device 1 and is fixedly connected with the bracket 100, the output end of the air cylinder 571 is fixedly connected with the plurality of suction nozzles 572 through a fixing plate, the air cylinder 571 and the vacuum pump are connected with the industrial personal computer 13, when the air cylinder 571 works, the air cylinder 571 moves downwards to the position where the suction nozzles 572 are contacted with the envelope body, then the vacuum pump works to generate negative pressure at the position of the suction nozzles 572, the suction nozzles 572 adsorb the envelope body, the air cylinder 571 moves upwards to open the envelope body to form a cavity, the envelope.

In the present embodiment, the letter transfer mechanism 52 and the letter acceleration mechanism 53 realize power output using the same power source. Specifically, the letter conveying mechanism 52 is provided with two transfer conveyor belts 521, a driving rotating shaft 522, a driven rotating shaft 523 and a transfer motor 524, which are arranged at intervals, wherein the two transfer conveyor belts 521 are sleeved on the driving rotating shaft 522 and the driven rotating shaft 523, and the transfer motor 524 is in transmission connection with the driving rotating shaft 522; the letter acceleration mechanism 53 has at least one acceleration module located above the transfer conveyor 521, the at least one acceleration module being located close to the first conveyor 1, the acceleration module comprising a connecting shaft 531 and friction wheels 532 fixed at both ends of the connecting shaft 531; wherein the rotation direction of the friction wheel 532 is opposite to the rotation direction of the driving rotating shaft 522, and the linear speed of the edge of the friction wheel 532 is higher than the moving speed of the conveyor belt 521. In this embodiment, the letter acceleration mechanism 53 is located above the front end of the letter transfer mechanism 52, and therefore, the friction wheel 532 and the rotation direction are opposite to the rotation direction of the driving rotation shaft 522 in order to achieve acceleration. As shown in fig. 8, when the driving shaft 522 rotates clockwise, the friction wheel 532 rotates counterclockwise. And the linear speed of the edge of the friction wheel 532 is higher than the conveying speed of the conveying belt 521, so that the acceleration of the letter can be realized. Specifically, power is transmitted among the transfer motor 524, the driving rotating shaft 522 and the friction wheel 532 through belts. In addition, in order to ensure the ejection stability after acceleration of the letter, two sets of acceleration assemblies arranged in parallel are arranged in the embodiment. In other embodiments, the connecting shaft 531 of the acceleration assembly may also be connected to a separate motor to provide power for use.

Specifically, the letter drop-in device 5 further has an auxiliary pulley 54, and the output end of the transfer motor 524 is in transmission connection with the connecting shaft 531, the driving rotating shaft 522 and the auxiliary pulley 54 through a transmission belt 55, so that the connecting shaft 531 and the driving shaft 522 rotate in opposite directions. The winding of the driving belt 531 may be performed in the manner shown in fig. 8, but is not limited thereto, and may be performed in any suitable manner as long as it is ensured that the rotation directions of the friction wheel 532 and the driving rotation shaft 522 are opposite. It will be appreciated that in this embodiment the friction wheel 532 effects acceleration of the letter by generating a friction force on the letter when in contact with the letter in a direction towards the first transferring device 1.

Preferably, to accommodate the packaging of electronic cards, such as credit cards. A card reader (not shown in the figure) is arranged below the letter transfer mechanism 51 and connected with the industrial personal computer 13 for detecting whether an electronic card exists in the letter transmitted by the letter transfer mechanism 51.

The flap 72 is an inclined member whose left side becomes larger to the right side, and the inner side surface of the sealing portion is turned over to be opposite to the envelope body under the action of the flap 72. In the process of continuously moving the envelope, the turned sealing part and the envelope body are guided into the compacting plate 73, and the sealing part and the envelope body are compacted and bonded by the compacting plate 73. For further bonding, further compaction is performed using press wheels 74.

After passing through the code scanner 9, the envelopes are conveyed to the second conveying device 2, which second conveying device 2 continues conveying the envelopes. When transferred to the weighing device 10, the weighing plane 101 is lifted, and the weight of the envelope is weighed at the weighing plane 101, and the resulting weight information is transferred to the industrial personal computer 13. The industrial personal computer 13 rejects the envelope which does not meet any one standard according to the information fed back by the code scanning device 9, the weighing device 10 and the card reader, and when the envelope is rejected, the industrial personal computer 13 controls the driving motor 1131 to operate upwards, so that the waste notch 111 is exposed, and the discarded envelope is rejected into the containing box 114 through the waste notch 111 under the action of the second transmission device 2; the waste notch 111 resets after the removal. Finally, the material is conveyed to the material receiving device 12 under the action of the second conveying device 2.

In a word, the technical scheme of the invention realizes the integrated operation of opening the seal of the envelope, filling the envelope, sealing, scanning the code, detecting and rejecting waste, combines devices with various functions into an integrated structure, and meets the use requirement of the logistics industry.
