[0048] In the embodiment of the present invention, the electrical control system includes an electrical control unit and an automatic control unit. The electrical control unit provides power to the pillow packaging machine 10, and controls the operation of the circuits, gas circuits or driving components between the various mechanisms. For example, the automatic positioning mechanism 700 is controlled to obtain the material image through the image device 710 (such as an RGB camera, an industrial CCD camera, etc.), and the material is identified according to the material image (which can be implemented by algorithms and software), and then the clamping unit 730 is driven by the mechanical arm 720 to clamp the material. Then, the positioning unit image in the first transmission mechanism 510 is obtained, and the specific position of the positioning unit 511 is identified according to the positioning unit image, and the material is placed in the positioning unit 511, so as to accurately control the material to be placed in the corresponding positioning unit 511. In this embodiment, the first transmission mechanism 510 and the second transmission mechanism 520 can be a transmission chain, a transmission belt, a belt, etc., and the positioning unit 511 can be a color mark, a symbol mark, a graphic mark, etc. Compared with the prior art of placing materials manually, which not only wastes manpower but also fails to accurately control the interval between each material, the automatic positioning mechanism 700 in this embodiment can not only automatically clamp the materials, but also accurately position the materials, saving manpower and being practical.

[0049] The automatic control unit in this embodiment will control the working process of the pillow packaging machine 10 according to a preset program, for example, control the feeding conveyor mechanism 500 to complete the transportation of materials, so that the first conveying mechanism 510 transports the materials from the feeding mechanism 100 to the tape unwinding mechanism 200, and the tape unwinding mechanism 200 performs film coating on the materials; the filmed materials are transported to the heat sealing mechanism 400 through the second conveying mechanism 520 from the leveling mechanism 300, and the heat sealing mechanism 400 performs heat sealing on the filmed materials, and finally the packaged materials are transported out through the discharging conveyor mechanism 600 to complete the packaging production process.

[0050] The specific working process of this embodiment:

[0051] The automatic positioning mechanism 700 obtains the material image through the imaging device 710, and quickly determines and identifies the material position, and starts the mechanical arm 720 to drive the clamping unit 730 to clamp the material. In other embodiments, the mechanical arm 720 can be set to multiple to speed up the loading speed. The mechanical arm 720 can be set to be retractable and 360° rotatable and movable as needed, and the arm lengths of each mechanical arm 720 can also be set to be the same or different. The response time of the automatic positioning mechanism 700 can be set by software to complete the automatic loading production. Figure 3, then, the automatic positioning mechanism 700 obtains the positioning unit image in the first transmission mechanism 510 through the imaging device 710, and after judging and identifying the positioning unit 511, the clamped material is placed in the positioning unit 511. The positioning unit 511 is used to accurately locate the position of each material, so that the tape unwinding mechanism 200 can film the material in an orderly manner. The third driving component drives the first transmission mechanism 510 and the second transmission mechanism 520 to operate respectively. The first transmission mechanism 510 transports the material from the feeding mechanism 100 to the tape unwinding mechanism 200. In other embodiments, the tape unwinding mechanism 200 can be set as an upper film structure or a lower film structure. Specifically, the lower film structure refers to setting the tape fixing unit at the bottom, the limiting unit and the longitudinal sealing unit 210 are set above the tape fixing unit, the first transmission mechanism 510 passes through the longitudinal sealing unit 210, and the limiting unit is used to limit the position of the material to prevent the material position from shifting and affecting the film production.

[0052] The tape unwinding mechanism 200 of this embodiment adopts an upper film structure, that is, the tape fixing unit is arranged above the limiting unit and the longitudinal sealing unit 210, the first transmission mechanism 510 passes through the longitudinal sealing unit 210, and the limiting unit is used to limit the position of the material. The tape unwinding mechanism 200 performs film production on the material, so that the material enters the packaging film when passing through the tape unwinding mechanism 200. The longitudinal sealing unit 210 folds the packaging film and seals the folded part of the packaging film, for example: a pair of roller-type resistance heating hot melt sealers are used to achieve continuous longitudinal sealing. The hot melt sealer can not only perform longitudinal heat sealing on the packaging film bag making, but also play a traction and conveying role on the packaging film bag making. Due to the use of the upper film structure, the longitudinal sealing strip will be located below the material. The material passing through the tape unwinding mechanism 200 will enter the packaging film, and the packaging film will be transported to the sweeping mechanism 300 with the material by the second transmission mechanism 520. The sweeping mechanism 300 is provided with a conveyor belt 310, and the first driving component drives the conveyor belt 310 to rotate cyclically. A circle of neatly arranged brushes 320 are installed on the conveyor belt 310. When the material passes through the leveling mechanism 300, the conveyor belt 310 rotates in a circle, driving the brushes 320 to level the packaging film, thereby ensuring the flatness and vacuum degree of the packaging bag. Subsequently, the leveled packaging film is transmitted to the heat sealing mechanism 400 along with the material by the second conveying mechanism 520. The second driving component drives the transverse sealing shaft 420 on each transverse sealing unit 410 to rotate. A plurality of transverse sealing bodies 430 are arranged on the transverse sealing shaft 420, and the transverse sealing bodies 430 heat-seal the material passing through the heat sealing mechanism 400. Specifically, when the material passes through the heat sealing mechanism 400, the transverse sealing shafts 420 in the two transverse sealing units 410 arranged adjacent to each other rotate alternately, for example, the upper transverse sealing shaft 420 is arranged to rotate counterclockwise, and the lower transverse sealing shaft 420 is arranged to rotate clockwise. When the two transverse sealing bodies 430 arranged adjacent to each other meet for the first time, the upper and lower transverse sealing bodies 430 are arranged relative to each other along the axis. When two transverse sealing bodies 430 arranged adjacent to each other meet, the working state of the two transverse sealing shafts 420 can be set to slow rotation or paused rotation to tightly fuse the two sealing surfaces on one side of the packaging film together; then the upper transverse sealing shaft 420 continues to rotate counterclockwise, and the lower transverse sealing shaft 420 continues to rotate clockwise, and the upper and lower two transverse sealing bodies 430 are staggered respectively, and the packaging film is transported to the discharging conveying mechanism 600 with the material. When the two transverse sealing bodies 430 arranged adjacent to each other meet for the second time, the upper and lower two transverse sealing bodies 430 are heated and operated at the same time to fuse and seal the two sealing surfaces on the other side of the packaging film together, thereby completing the packaging of the material in the packaging film. According to the preset temperature of the electrical control system, the heat sealing mechanism 400 is always kept at a high temperature to heat-package the material. The temperature sensor detects the temperature in the heat sealing mechanism 400 in real time. When the temperature is abnormal, it can transmit a signal to the electrical control system in time to remind the staff to observe the machine to ensure normal operation of production.The packaged material is output by the heat sealing mechanism 400 and reaches the discharging conveying mechanism 600. The fourth driving component drives the discharging conveying mechanism 600 to operate and discharge the packaged material, thereby completing the automatic packaging production of the material.

[0053] In other embodiments, the material may be food such as tea bags, moon cakes, chocolates, instant noodles, etc., or may be daily necessities such as films and soaps.

[0054] One or more technical solutions provided by the present invention have at least the following beneficial effects: the pillow packaging machine 10 of the embodiment of the present invention can automatically perform production processes such as material loading, film application and packaging, realize the industrial assembly line production mode, reduce manual participation, save manpower and material resources, and can accurately control the material loading process to reduce defective products.

[0055] Reference Figure 2 According to some embodiments of the present invention, two transverse sealing bodies 430 are provided on each transverse sealing shaft 420, and a heating unit is provided inside each transverse sealing body 430, the positive pole of the heating unit is connected to the positive pole wire, and the negative pole is connected to the negative pole wire, and the positive pole wire and the negative pole wire are respectively connected to the electrical control unit.

[0056] In this embodiment, a heating unit is provided inside each transverse sealing body 430, and the heating unit is used to seal the packaging film. Existing materials are generally packaged with plastic films, and the plastic films are generally sealed by a hot melt sealing method.

[0057] Specifically, the material processed by the longitudinal sealing unit 210 will enter the packaging film, and the packaging film has completed the longitudinal sealing package. After that, the material is transported to the heat sealing mechanism 400 by the second transmission mechanism 520, and the second driving component drives each transverse sealing shaft 420 in the heat sealing mechanism 400 to rotate continuously, so as to drive the two transverse sealing bodies 430 on each transverse sealing shaft 420 to rotate alternately. When the two transverse sealing bodies 430 arranged adjacent to each other above and below contact the packaging film respectively, the heating unit quickly heats the two contact surfaces of the packaging film to make it in a molten thermoplastic state. In other embodiments, it can also be set to apply pressure to the sealing part so that the two sealing surfaces of the packaging film are fused and sealed together to enhance the firmness. In other embodiments, there are many forms of heat-melt sealing methods, generally resistance heating method and pulse heating method, in addition to high-frequency electric heating sealing, ultrasonic heating sealing, electromagnetic heating sealing and infrared heating sealing. However, this embodiment adopts the resistance heating method because it has the characteristics of simple structure and convenient regulation.

[0059] In this embodiment, two flower shears are also provided on each transverse sealing shaft 420. The material is transported to the heat sealing mechanism 400 by the second transmission mechanism 520. The second driving component drives each transverse sealing shaft 420 in the heat sealing mechanism 400 to rotate continuously, so as to drive the two flower shears on the transverse sealing shaft 420 to rotate alternately, and the material enters the recesses of the two flower shears. Since the flower shears are radially protruded with a transverse sealing body 430, a transverse sealing strip and a cutter are recessed at the end of the transverse sealing body 430. During the working process, when two transverse sealing bodies 430 arranged adjacent to each other meet for the first time, since a heating unit is provided inside each transverse sealing body 430, the high temperature is transmitted to the transverse sealing strip, so that when the transverse sealing strip contacts the packaging film, the two sealing surfaces of the packaging film are quickly heated, so that the two sealing surfaces of the packaging film are in a molten thermoplastic state, so that the two sealing surfaces of the packaging film are fused and sealed together. Afterwards, two scissors arranged adjacent to each other operate on the packaged packaging film, for example, to make both sides of the packaging film have toothed laces (the distance between the two scissors is greater than the distance between the two horizontal seals); at the same time, the cutter cuts the scissors to cut the packaged material, thereby completing the packaging production of the material. The scissors are used to set laces on the packaged material, which is convenient for consumers to tear open the package; and the cutter cuts the packaged materials one by one, which is convenient for the materials to be sold separately, reducing the input of labor and having practicality.

[0060] According to some embodiments of the present invention, a liquid crystal touch screen connected to the automatic control unit is provided outside the electrical control system. The liquid crystal touch screen is provided to facilitate the control of the operation of the electrical control system. For example, the interactive interface of the entire electrical control system can be viewed through the liquid crystal touch screen, and the transmission speeds of the feeding conveyor mechanism 500 and the discharging conveyor mechanism 600 can be set respectively; the transmission speed of the conveyor belt 310; the heating temperature and heating time of the heat sealing mechanism 400; the power on and off and pause of the pillow packaging machine 10, etc., so that the user can observe and control the operation process of the pillow packaging machine 10.

The hopper is used to hold materials, and the vibrating screen is used to transport materials out in an orderly manner, and can screen and remove unqualified materials, for example, using a wind separator to remove impurities whose particles are larger than the materials. The feeding mechanism 800 transports the materials to the rack 20 in an orderly manner, and the automatic positioning mechanism 700 obtains the material image and identifies the material and clamps the material through the clamping unit 730, and puts the material into the positioning unit 511 in the feeding mechanism 100 accordingly, so that the materials are neatly arranged on the first transmission mechanism 510, and the materials are transported to the tape unwinding mechanism 200 through the first transmission mechanism 510 for further packaging and production of materials.
