[0044] like Figure 1 , Figure 2 , Figure 10~Figure 13As shown, the outer bag loading unit 2 is arranged on the outer peripheral side of the transfer unit 1, and is used to load n outer bags 6 to the transfer unit 1, including n outer bag loading components, and the outer bag loading components include a bottom plate 21 arranged on a second bracket 212, a plurality of rotating seats 211 are arrayed on one side of the bottom plate 21, and a plurality of second rotating motors 22 are arrayed on the other side of the bottom plate 21, one end of the output shaft of the second rotating motor 22 is rotatably matched with the rotating seat 211, and a friction wheel 221 is also fixed on the outer peripheral side of the output shaft of the second rotating motor 22, and a bag placing frame 23 fixed to the top of the food bagging workshop by a hanging plate 231 is provided at a predetermined distance above the bottom plate 21. For the convenience of representation, Figure 1 , Figure 2The hanging plate 231 is not shown in the figure. The bag placing frame 23 is used to place multiple outer bags 6 with one end open, and the opening is facing the direction of the transfer unit 1 when placing. One end of the bottom end of the bag placing frame 23 is provided with a bag dividing plate 232. The inner end thickness of the bag dividing plate 232 is less than the outer end thickness. The upper end surface of the bag dividing plate 232 is a plane, and the lower end surface is an inclined surface with a reduced height outward. The second rotating motors 22 under the bag dividing plate 232 are also arranged obliquely in a direction parallel to the cross-sectional edge line of the lower end surface of the bag dividing plate 232. The outer end surface of the bottom end of the bag placing frame 23 is extended with an upper limit plate 233. The distance between the bottom end surface of the upper limit plate 233 and the bottom end of the side surface of the bag placing frame 23 is equal to the thickness of an outer bag 6. The friction wheels 221 arranged in an array first move an outer bag 6 to a position away from the bag dividing plate 232, and at this time, part of the outer bag 6 is located between the upper limit plate 233 and several friction wheels 221, and then the outer bag 6 is transported in the opposite direction, and the outer bag 6 is transported from the bottom of the bag dividing plate 232 to the direction of the transfer unit 1 through the bag dividing plate 232, until part of the outer bag 6 is transported to the outer end below the bag placing frame 23, and a first bracket is also provided on one side of the bottom plate 21, and a first linear mechanism 24 is provided on the first bracket, and a third rotating motor 25 is provided at one end of the output shaft thereof, and a second clamping mechanism 26 is provided at one end of the output shaft of the third rotating motor 25, and the second clamping mechanism 26 clamps After holding the outer bag 6 of the bag placing frame 23 being conveyed, the outer bag 6 is pushed out through the first linear mechanism 24, and then the outer bag 6 is rotated to a vertical position by the third rotating motor 25, and is located between a pair of first clamping mechanisms 16, and at this time, the springs 13 at the ends of the pair of guide rods 14 are in a natural state and stretched, and the vertical rod 15 under the guide rod 14 is located at the outermost position on the outer rail 171, so the distance between the pair of first clamping mechanisms 16 is large, which is greater than the width of the outer bag 6 being conveyed, and the outer bag feeding assembly also includes a second linear mechanism 27 arranged on the third bracket 271, and a vertical third linear mechanism 28 is provided at one end of its output shaft, and the third linear mechanism 28 outputs An L-shaped plate 29 is provided at the upper end of the shaft. When an outer bag 6 is located between a pair of first clamping mechanisms 16, the L-shaped plate 29 is raised by the third linear mechanism 28, and then pushed by the second linear mechanism 27. The vertical part of the L-shaped plate 29 pushes the vertical plate 141, so that the vertical rod 15 is located at the outer bag loading point 172. In this process, the pair of first clamping mechanisms 16 are started to clamp the outer bag 6 from the side, and at the same time, the second clamping mechanism 26 is released, the spring 13 is compressed, and the L-shaped plate 29 is kept stationary until the output shaft of the first rotating motor 11 rotates a predetermined angle, that is, the n vertical rods 15 are respectively moved to the n bag supporting points 173, and then the L-shaped plate 29 is retracted.

[0045] like Figure 1 , Figure 2 , Fig.14 , Fig.15As shown, the bag-stretching unit 3 is arranged on the outer peripheral side of the transfer unit 1, and is used to stretch open the openings of n outer bags 6, including a fourth linear mechanism 31 vertically arranged on the fourth bracket 311, a transverse plate 32 is provided at the upper end of the output shaft of the fourth linear mechanism 31, a branch plate 33 is provided at one end of the transverse plate 32, and n bag-stretching assemblies are provided on the lower end surface of the branch plate 33, and the bag-stretching assembly includes a pair of fourth rotating motors 34 arranged oppositely, a cone rod 35 is provided at one end of the output shaft of the fourth rotating motor 34, a transverse rod is provided at one end of the cone rod 35, and a rotating plate 36 is rotatably matched on the outer peripheral side of the transverse rod, and a rotating block 37 is provided at the lower end of the rotating plate 36, and the cross section of the rotating block 37 is an inverted triangle, and a stretching piece 38 is provided at the lower end of the rotating block 37. The pair of stretching pieces 38 of the bag-stretching assembly are used to stretch open the opening of the outer bag 6. In addition, by reducing the spacing between a pair of first clamping mechanisms 16 that clamp the outer bag 6, the opening of the outer bag 6 can be further stretched.

[0046] like Figure 1 , Figure 2 , Fig.16 As shown, the inner bag placement unit 4 is arranged on the outer peripheral side of the transfer unit 1, and is used to place inner bags in n outer bags 6 respectively located on the outside of the inner bag placement points 174, including n inner bag placement components, and the inner bag placement components include a conveyor machine 41 arranged on the fifth bracket 411, which is used to transport the inner bags. A second bracket is provided on one side of the conveyor machine 41, and a fifth linear mechanism 42 is provided on the second bracket, and a fifth rotating motor 43 is provided at one end of the output shaft of the fifth rotating motor 43. A third clamping mechanism 44 is provided at one end of the output shaft of the fifth rotating motor 43, which is used to clamp the inner bag at the conveying end of the conveyor machine 41. Specifically, the inner bag placement unit 4 is arranged at a higher position, so that after the inner bag is clamped and pushed out, it can be placed in the outer bag 6 from top to bottom.

[0047] like Figure 1 , Figure 2 As shown, the sealing unit 5 is arranged on the outer peripheral side of the transfer unit 1, and the outer bag feeding unit 2, the bag supporting unit 3, the inner bag placing unit 4, and the sealing unit 5 are arranged in sequence around the outer periphery of the transfer unit 1. The sealing unit 5 is used to seal n outer bags 6 respectively located outside the sealing points 175. The sealing unit 5 includes n heat sealers 51 arranged on the sixth bracket 52. When the outer bag 6 is heat-sealed in the working part of the heat sealer 51, the distance between a pair of first clamping mechanisms 16 clamping the outer bag 6 increases, so that the outer bag 6 is closed.

[0048] In this embodiment, n=2, the first clamping mechanism 16, the second clamping mechanism 26, and the third clamping mechanism 44 all use air clamps, and the first linear mechanism 24, the second linear mechanism 27, the third linear mechanism 28, the fourth linear mechanism 31, and the fifth linear mechanism 42 all use single-axis linear cylinders.

[0049] Working method:

[0050] First, a plurality of outer bags 6 are placed in each bag placing frame 23, and then the n outer bags are transferred to the n pairs of first clamping mechanisms 16 closest to the outer bag loading unit 2 for clamping through the outer bag loading unit 2, and the specific method has been described above.

[0051] Next, since the outer bag 6 is flat in the default state, it needs to be stretched open by the outer bag loading unit 2. After the outer bag 6 transferred in front is rotated to the inner side of the bag stretching unit 3 by the first rotating motor 11, the outer bag 6 is stretched open in the manner described above. Specifically, at this time, the distance from the bag stretching point 173 to the axis of the first rotating motor 11 is b, that is, the vertical rod 15 drives the vertical plate 141 to move in the direction closest to the output shaft of the first rotating motor 11, and the distance between the two first clamping mechanisms 16 is thereby reduced.

[0052] After the outer bag 6 is opened, the first rotating motor 11 continues to rotate the outer bag 6, and the distance from the inner bag placement point 174 to the axis of the first rotating motor 11 is also b, that is, the outer bag 6 is kept opened, and then the inner bag is clamped by the third clamping mechanism 44, and then the inner bag is vertically located above the outer bag 6 through the fifth linear mechanism 42 and the fifth rotating motor 43, and then the clamping is released to allow the inner bag to fall into the outer bag 6.

[0053] Then, the outer bags 6 are rotated by the first rotating motor 11 to move the n outer bags 6 to the position where the sealing unit 5 is located, and the openings of the outer bags 6 are heat-sealed to complete the food bagging process.

[0054] Specifically, a box may be provided below the sealing position of the outer bag 6 to collect the bagged food.

[0055] When the above-mentioned outer bag loading, outer bag opening, inner bag loading and sealing are being performed, the corresponding positions can be operated continuously at the front points to realize automatic and continuous food bagging.

[0056] The above are only some of the embodiments listed in this application and are not intended to limit this application.
