In the present invention, the structures of the film placing device 1, the package bag forming device 2, the longitudinal sealing device 3, the filling device 4 and the sealing device 5 are all mature, and the existing mature structures, for example, the structures and specific arrangement modes of the film placing device 1, the package bag forming device 2, the longitudinal sealing device 3, the filling device 4 and the sealing device 5, can also be directly adopted by the packaging material supply unit, the folding part, the first sealing element, the filling part and the second sealing part disclosed in application number JP 2010144568.

In the invention, when the characteristics of various solid materials to be filled are different, for example, in the case of co-packaging seasoning powder and dehydrated vegetables, the characteristics of the seasoning powder and the dehydrated vegetables are different, the seasoning powder is easy to adhere to equipment, and is easy to damp and corrode the equipment along with the time, and the dehydrated vegetables cannot be corroded, so that the multi-material automatic packaging production line further comprises a main material feeding system 6 and an auxiliary material feeding system 7 aiming at different materials, wherein the main material feeding system 6 is used for feeding the powder which is easy to damp, and the auxiliary material feeding system 7 is used for feeding the dehydrated vegetables which are not easy to influence. Here, only to be convenient for distinguish main material feeding system 6 and auxiliary material feeding system 7, but in practical application process, main material feeding system 6 and auxiliary material feeding system 7 also can carry out the material of the same nature simultaneously, and main material feeding system 6 and auxiliary material feeding system 7 also can not distinguish this moment, and main material feeding system 6 and auxiliary material feeding system 7 can adopt the same structure.

The charging device 4 is characterized in that a blanking device 8 is further arranged above the charging device 4, the blanking device 8 is mainly used for enabling materials fed by the main material feeding system 6 and the auxiliary material feeding system 7 to drop into the filling hopper 402 of the charging device 4 in a transition mode after being mixed, the blanking device 8 comprises a main material blanking unit 801 and an auxiliary material blanking unit 802, materials fed by the main material feeding system 6 are fed into the main material blanking unit 801, materials fed by the auxiliary material feeding system 7 are fed into the auxiliary material blanking unit 802, the main material blanking unit 801 is located above the auxiliary material blanking unit 802, and the auxiliary material blanking unit 802 can sufficiently rotate below the main material blanking unit 801. The main material blanking unit 801 is provided with at least one blanking port 8014, when the blanking port 8014 is used for blanking the required amount of the material package each time, the blanking port 8014 on the main material blanking unit 801 is one, and when the common blanking amount of the plurality of blanking ports 8014 is the required amount of the material package, the number of the blanking ports 8014 on the main material blanking unit 801 is multiple, but no matter how many the blanking ports 8014 on the main material blanking unit 801 are, the positions of the blanking ports 8014 are all positioned behind the filling station of the filling device 4, so that the material is blanked before filling. The direction behind the filling station of the filling device 4 is a reference direction with respect to the rotation direction of the filling device 4.

The auxiliary blanking unit is provided with at least one collecting hopper 8022, of course, the number of the collecting hoppers 8022 is preferably a plurality of, and the number of the collecting hoppers 8022 is larger than the number of the material types; in one aspect, the material is of a type greater than 1; on the other hand, the materials in one collecting hopper 8022 can fall onto the filling station of the filling device 4, and meanwhile, the main materials on the main material blanking unit 801 can fall into other collecting hoppers 8022 through the blanking openings 8014 to be mixed with other materials in the collecting hoppers 8022 to form a mixture, so that the packaging efficiency can be effectively improved greatly. Of course, since the auxiliary material blanking unit 802 can rotate below the main material blanking unit 801, in order to ensure that the material falling through the blanking port 8014 can accurately fall into the collecting hopper 8022, the blanking port 8014 and the collecting hopper 8022 have a height difference, but the blanking port 8014 and the collecting hopper 8022 need to be ensured on the same circumference, so that the blanking port 8014 can accurately correspond to the collecting hopper 8022 when the auxiliary material blanking unit 802 reaches a certain position in the rotation process.

Since it is only necessary to ensure that the collection hoppers 8022 finish blanking when reaching the filling station of the filling device 4, the number of the collection hoppers 8022 may be equal or unequal to the number of the filling hoppers 402 on the filling device 4 when the collection hoppers 8022 are designed. When the number of the collecting hoppers 8022 is equal to that of the filling hoppers 402 on the filling device 4, the collecting hoppers 8022 are in one-to-one correspondence with the filling hoppers 402 on the filling device 4, the circles formed by the outlets of the collecting hoppers 8022 are concentric with the circles formed by the filling hoppers 402 on the filling device 4, the auxiliary material blanking units 802 and the filling device 4 rotate synchronously, and when the positions of the corresponding collecting hoppers 8022 and filling hoppers 402 on the filling device 4 reach the filling stations, the materials in the collecting hoppers 8022 fall into the filling hoppers 402 on the filling device 4 and enter the corresponding packaging bags when the materials in the filling hoppers 402 on the filling device 4 are discharged and fed into the corresponding packaging bags; when the number of the collecting hoppers 8022 is equal to that of the filling hoppers 402 on the filling device 4, it is required to ensure that when the auxiliary material blanking unit 802 rotates, one of the collecting hoppers 8022 on the auxiliary material blanking unit 802 corresponds to the filling hopper 402 on the filling device 4 at the filling station of the filling device 4, that is, a circle formed by the outlets of the plurality of collecting hoppers 8022 and a circle formed by the plurality of filling hoppers 402 on the filling device 4 are eccentrically arranged, at this time, the rotation of the auxiliary material blanking unit 802 and the filling device 4 is not synchronous, but when the positions of the collecting hoppers 8022 and the filling hoppers 402 on the filling device 4 reach the filling station, the material in the collecting hoppers 8022 can fall into the filling hoppers 402 on the filling device 4, and the material in the filling hoppers 402 is discharged and fed into corresponding packaging bags, that is, in this case, the filling work can be completed.

When the material is packaged, the film strips used for the packaging bags are arranged on the film placing device 1, the film strips are firstly pulled manually to sequentially pass through the packaging bag forming device 2, the longitudinal sealing device 3, the filling device 4 and the sealing device 5, the film placing device 1, the packaging bag forming device 2, the longitudinal sealing device 3, the filling device 4, the sealing device 5, the main material feeding system 6, the auxiliary material feeding system 7, the main material blanking unit 801 and the auxiliary material blanking unit 802 respectively act, the film strips start to be conveyed, when the film strips pass through the packaging bag forming device 2, the packaging bag forming device 2 guides the film strips to be folded in the conveying direction to form V-shaped film strips, the folded film strips continue to advance, when the folded film strips reach the longitudinal sealing device 3, the film strips form packaging bags with open upper ends between the two longitudinal sealing positions after the longitudinal sealing, and the film strips continue to be conveyed forwards after the longitudinal sealing.

When the film strip passes through the packaging bag forming device 2 and the longitudinal sealing device 3, the main material feeding system 6 and the auxiliary material feeding system 7 respectively feed the main material and the auxiliary material to be packaged, meanwhile, the auxiliary material blanking unit 802 rotates, the main material fed by the main material feeding system 6 sequentially drops into a plurality of collecting hoppers 8022 on the auxiliary material blanking unit 802 through the blanking port 8014 in the rotating process, the auxiliary material fed by the auxiliary material feeding system 7 sequentially drops into a plurality of collecting hoppers 8022 on the auxiliary material blanking unit 802 while the auxiliary material blanking unit 802 rotates, so that the main material and the auxiliary material form a mixture in the collecting hoppers 8022, and when the collecting hoppers 8022 filled with the mixture correspond to the filling hoppers 402 on the filling device 4 and are positioned at the filling stations of the filling device 4, the mixture in the collecting hoppers 8022 drops into the filling hoppers 402 on the filling device 4, and the materials in the filling hoppers 402 are discharged and fed into the corresponding packaging bags on the filling device 4, so that the materials are filled.

And the filled material strips are continuously conveyed, when the material strips enter the sealing device 5, the sealing device 5 performs plastic package on the upper edges of the material strips, so that a plurality of continuous material strips of packaging bags are formed, and the packaging of materials is completed.

As a further improvement of this embodiment, in order to avoid that one of the film rolls on the film releasing device 1 needs to be pulled from a new film roll after the use is completed, a film receiving device 9 may be further disposed between the film releasing device 1 and the packaging bag forming device 2, and the film receiving device 9 may directly adopt the film receiving device 9 in the prior art, for example, an automatic film receiving mechanism for film bag making disclosed in application number 2020215305272, so as to not only improve packaging efficiency, but also effectively reduce waste of the film roll.

As shown in fig. 2 and 3, the main material feeding system 6 and the auxiliary material feeding system 7 each include a material storage tank 606 and a negative pressure feeding device 607 sequentially arranged along the material conveying direction; the storage tank 606 is used for storing materials to be fed, and when the storage tank 606 is installed, the storage tank 606 can be directly installed on the ground through a rack, so that the materials to be fed can be conveniently fed into the storage tank 606; the negative pressure loading device 607 is used for feeding the material in the material storage tank 606 into the intermediate material tank 701 by adopting a negative pressure principle. The negative pressure feeding device 607 in the main material feeding system 6 is directly installed on the main material storage vat 601, and the outlet end of the negative pressure feeding device 607 is communicated with the inside of the main material storage vat 601, so that the main material fed by the negative pressure feeding device 607 can directly enter the main material storage vat 601. The auxiliary material feeding system 7 further comprises an intermediate charging basket 701 and a vibration charging device 702 which are sequentially arranged at the outlet end of the negative pressure charging device 607, and the intermediate charging basket 701 stores auxiliary materials; the vibration feeding device 702 is configured to send the auxiliary material stored in the intermediate bucket 701 out in a vibration manner, and make the sent auxiliary material enter the collecting hopper 8022. In order to avoid influencing the rotation of the collecting hopper 8022, the outlet end of the vibration feeding device 702 is in drop-type butt joint with the collecting hopper 8022 in design, namely, the outlet end of the vibration feeding device 702 is in butt joint with the upper part of the opening of the collecting hopper 8022, so that the vibration feeding device 702 is not in direct contact with the collecting hopper 8022, and the collecting hopper 8022 can normally rotate while the auxiliary materials are fed into the collecting hopper 8022. In order to prevent the auxiliary material from being fed into the collecting hopper 8022 when the collecting hopper 8022 reaches the filling station of the filling device 4, it is necessary to ensure that the collecting hopper 8022 can reach the filling station of the filling device 4 after the auxiliary material is fed into the collecting hopper 8022, and the vibrating feeding device 702 is required to ensure that the outlet end of the vibrating feeding device 702 is positioned behind the filling station in the filling device 4 when the vibrating feeding device 702 is installed, so that the vibrating feeding device 702 can enter the filling station of the filling device 4 after the auxiliary material is fed into the collecting hopper 8022, and the filling of the auxiliary material is ensured.

Here, when the auxiliary materials are multiple, on one hand, in order to arrange the multiple auxiliary material feeding systems 7, on the other hand, in order to facilitate arranging the outlet ends of the multiple vibration feeding devices 702, in the present invention, the multiple vibration feeding devices 702 and the discharge openings 8014 may respectively correspond to different collecting hoppers 8022, so that the main materials and the auxiliary materials may be sequentially fed into the collecting hoppers 8022 while the collecting hoppers 8022 rotate, which will not affect the filling of the filling device 4, and will not affect the packaging efficiency.

As a further improvement of the present embodiment, as shown in fig. 4, the negative pressure feeding device 607 includes a negative pressure cylinder 6071, the negative pressure cylinder 6071 in the main material feeding system 6 is directly installed at the top of the main material storage vat 601, the negative pressure cylinder 6071 in the auxiliary material feeding system 7 is directly installed at the top of the intermediate storage vat 701, the lower end of the negative pressure cylinder 6071 is directly communicated with the inside of the main material storage vat 601 or the inside of the intermediate storage vat 701, and the middle part of the negative pressure cylinder 6071 is also provided with an openable gate 6072, the gate 6072 divides the inside of the negative pressure cylinder 6071 into an upper chamber 6073 and a lower chamber 6074, at this time, the upper chamber 6073 is an independent chamber, and the lower chamber 6074 is communicated with the main material storage vat 601 or the intermediate storage vat 701; the gate 6072 is an automatic switch valve, which is a direct use of the existing gate 6072, and the negative pressure cylinder 6071 is provided with a material conveying pipe 6075, one end of the material conveying pipe 6075 is communicated with the upper chamber 6073, and the other end of the material conveying pipe 6075 is connected with the material storage tank 606; the negative pressure feeding device 607 further comprises an air pump 6076, and when the air pump 6076 rotates, the air pump 6076 vacuumizes the upper chamber 6073.

When the air pump 6076 vacuumizes the upper chamber 6073, the air pressure in the upper chamber 6073 is smaller than the external atmospheric pressure because the gate 6072 is in a closed state, and according to the conservation of pressure, the material in the storage tank 606 can enter the upper chamber 6073 through the material conveying pipe 6075, after the material enters the upper chamber 6073, the air pump 6076 stops rotating, the material entering the negative pressure cylinder 6071 is not attracted, the gate 6072 is opened, and the material falls down through self gravity, so that the material enters the middle material barrel 701 or the main material storage barrel 601.

As a further improvement of this embodiment, since there is a certain installation height difference between the storage vat and the negative pressure cylinder 6071, when the material conveying pipe 6075 is installed, two ends of the material conveying pipe 6075 need to be bent, so as to reduce the processing difficulty and cost of the material conveying pipe 6075, two ends of the material conveying pipe 6075 can be connected with the negative pressure cylinder 6071 through a hose, and the connection of the material conveying pipe 6075 is more convenient while the material conveying is ensured.

As a further improvement of the present embodiment, the main material feeding system 6 and the auxiliary material feeding system 7 further include a mounting base 608, when being mounted, the mounting base 608 may be directly mounted on the ground, and the mounting base 608 is further provided with a receiving hopper 609, the receiving hopper 609 is located below the outlet end of the storage tank 606, but in order to avoid that the material in the storage tank 606 overflows the receiving hopper 609 after falling on the receiving hopper 609, side baffles may be disposed on three sides of the receiving hopper 609, and the outlet of the storage tank 606 is lower than the side baffles; meanwhile, the inlet end of the material conveying pipe 6075 is arranged in a horn shape, so that the structure from the material conveying pipe 6075 to the inlet end is the same as that of the pipeline inlet end of the dust collector, and one end of the receiving hopper 609, which is not provided with a side baffle, is inserted into the inlet end of the material conveying pipe 6075.

As a further improvement of this embodiment, the mounting base 608 is further provided with a first linear vibrator 610, and the receiving hopper 609 is mounted in the first linear vibrator 610, so that after the material in the storage tank 606 falls on the receiving hopper 609, the material in the receiving hopper 609 can be sent into the material conveying pipe 6075 through the vibration of the first linear vibrator 610, and the difference of the amount entering into the material conveying pipe 6075 each time is smaller, so that the feeding effect is better.

As a further improvement of the present embodiment, the negative pressure cylinder 6071 is further provided with a vent pipe 6077 that is communicated with the lower chamber 6074, and the vent pipe 6077 communicates the lower chamber 6074 with the outside, so that the pressure in the lower chamber 6074 is consistent with the atmospheric pressure, and the gate 6072 can rapidly release the pressure in the negative pressure cylinder 6071 when being opened, thereby ensuring that the material in the upper chamber 6073 can normally fall; meanwhile, in order to prevent dust in the air from entering the lower chamber 6074 to pollute materials, a ventilation net 60710 can be arranged on the ventilation pipe 6077, so that the dust is prevented from entering the negative pressure cylinder 6071 while the lower chamber 6074 is communicated with the outside, and the feeding environment is cleaner and more sanitary.

As a further improvement of the present embodiment, an air pipe 6078 is connected between the outlet end of the air pump 6076 and the upper chamber 6073, and the air pipe 6078 is located at the top of the upper chamber 6073 or at the upper end of the upper chamber 6073, so that the installation height of the air pipe 6078 is higher than the height of the outlet end of the material conveying pipe 6075, so that the material can enter the air pipe 6078 only by moving upwards after entering the upper chamber 6073, the movement difficulty of the material in the upper chamber 6073 is increased, and the material is prevented from entering the air pipe 6078; meanwhile, in order to thoroughly avoid the material from entering the air pipeline 6078, a filter screen 6079 can be further arranged in the upper chamber 6073, the installation position of the filter screen 6079 is located between the outlet end of the material conveying pipe 6075 and the inlet end of the air pipeline 6078, the aperture of the filter screen 6079 is smaller than the diameter of the material, and the material is isolated below the filter screen 6079 while the air can pass through the filter screen 6079.
