[0041] Based on the above, this embodiment realizes automatic packaging of products through the first packaging device 1 and the second packaging device 2, thereby improving the work efficiency of the packaging operation and further improving the production efficiency of the product. Moreover, this embodiment will seal the inner bag during the packaging process, thereby preventing subsequent products from slipping out of the inner bag during transportation, thereby preventing the consumer's shopping experience from being affected by the product being exposed from the inner bag, and ensuring that the inner bag can always protect the product to prevent the product from being damaged due to collision during transportation.

[0042] Exemplarily, this embodiment is described by taking the product as a mouse and the outer packaging body as a packaging box as an example. The first packaging device 1 first puts the mouse into the inner bag. Specifically, the opening mechanism 11 is used to open the bag mouth of the inner bag, and the first pushing mechanism 12 is used to push the mouse into the inner bag from the opened bag mouth. The second packaging device 2 then puts the inner bag containing the mouse into the packaging box. Specifically, the folding mechanism 21 first folds the inner bag containing the mouse so that the part of the inner bag adjacent to the bag mouth is folded upward and close to the side of the inner bag away from the bag mouth, thereby enclosing the mouse in the inner bag. The second pushing mechanism 22 subsequently pushes the folded inner bag into the packaging box.

[0043] Based on the above, in the present embodiment, the first packaging device 1 is arranged at the first packaging station 41, and also includes a first carrier 13, the first carrier 13 is configured to carry products, the second packaging device 2 is arranged at the second packaging station 42, the product packaging equipment also includes an inner bag transfer device 3, the inner bag transfer device 3 includes a second carrier 31, the inner bag can be carried on the second carrier 31, the second carrier 31 can be moved to the first packaging station 41 and the second packaging station 42 in sequence, so that the inner bag can be in the first packaging station 41 and the second packaging station 42 in sequence.

[0044] When the inner bag is located at the first packaging station 41, the opening mechanism 11 opens the bag mouth of the inner bag, and the first pushing mechanism 12 pushes the product placed on the first carrier 13 into the inner bag through the opened bag mouth. Subsequently, the second carrier 31 moves to the second packaging station 42, the folding mechanism 21 folds the inner bag to seal the product in the inner bag, and the second pushing mechanism 22 pushes the folded inner bag into the packaging box.

[0045] From the above, the opening mechanism 11 includes two suction cups, specifically, the two suction cups are respectively a first suction cup 111 and a second suction cup 112, the first suction cup 111 and the second suction cup 112 are arranged opposite to each other in the vertical direction, specifically, the upper suction cup is used as the first suction cup 111, and the lower suction cup is used as the second suction cup 112, that is, the first suction cup 111 is located above the second suction cup 112, in addition to the first suction cup 111 and the second suction cup 112, the opening mechanism 11 also includes a first driving member 113, and the first driving member 113 is configured to drive the first suction cup 111 Moving in the vertical direction, when the inner bag is located at the first packaging station 41, the portion of the lower bag body of the inner bag adjacent to the bag opening is supported on the second suction cup 112, and the second suction cup 112 can adsorb the portion of the lower bag body of the inner bag adjacent to the bag opening, and the first driving member 113 drives the first suction cup 111 to descend in the vertical direction so that the first suction cup 111 can adsorb the portion of the upper bag body of the inner bag adjacent to the bag opening, and then, the first driving member 113 drives the first suction cup 111 to rise in the vertical direction to move away from the second suction cup 112, so that the bag opening of the inner bag can be opened.

[0046] Exemplarily, the first driving member 113 may be a linear driving structure such as a pneumatic cylinder or an electric cylinder, and this embodiment does not impose any specific limitation on this.

[0047] It is understandable that in other optional embodiments, the first driving member 113 may also be configured to drive the first suction cup 111 and the second suction cup 112 to move in the vertical direction together, or the first driving member 113 may also be configured to only drive the second suction cup 112 to move in the vertical direction, and this embodiment does not impose any specific restrictions on this. Specifically, for the first driving member 113 configured to drive the first suction cup 111 and the second suction cup 112 to move together in the vertical direction, the first driving member 113 can drive the first suction cup 111 and the second suction cup 112 to move relative to or away from each other in the vertical direction. When the inner bag is located at the first packaging station 41, the portion of the inner bag adjacent to the bag opening can be between the first suction cup 111 and the second suction cup 112. The first driving member 113 drives the first suction cup 111 and the second suction cup 112 to move relative to each other in the vertical direction, so that the first suction cup 111 can absorb the portion of the upper bag body of the inner bag adjacent to the bag opening, and the second suction cup 112 can absorb the portion of the lower bag body of the inner bag adjacent to the bag opening. Afterwards, the first driving member 113 drives the first suction cup 111 and the second suction cup 112 to move away from each other in the vertical direction, so that the bag opening of the inner bag can be opened. As for the first driving member 113 which is configured to only drive the second suction cup 112 to move in the vertical direction, when the inner bag is located at the first packaging station 41, the portion of the upper bag body of the inner bag adjacent to the bag opening is in contact with the first suction cup 111, and the first suction cup 111 can adsorb the portion of the upper bag body of the inner bag adjacent to the bag opening. The first driving member 113 drives the second suction cup 112 to rise in the vertical direction so that the second suction cup 112 can adsorb the portion of the lower bag body of the inner bag adjacent to the bag opening. Thereafter, the first driving member 113 drives the second suction cup 112 to descend in the vertical direction to move away from the first suction cup 111, so that the bag opening of the inner bag can be opened.

[0048] In addition, it is worth mentioning that in the present embodiment, an opening 311 is provided on one side of the second carrier 31, and a portion of the inner bag adjacent to the bag opening extends out of the second carrier 31 through the opening 311. When the second carrier 31 is located at the first packaging station 41, the portion of the inner bag extending out of the second carrier 31 can be between the first suction cup 111 and the second suction cup 112.

[0049] In addition to the first suction cup 111 and the second suction cup 112, the opening mechanism 11 also includes a carrier plate 114, on which suction holes 1141 are provided. It can be understood that the suction holes 1141 are connected to a vacuum generator (not shown in the figure), so that a negative pressure environment can be formed in the suction holes 1141. When the inner bag is located at the first packaging station 41, the parts of the inner bag adjacent to the first suction cup 111 and the second suction cup 112 are placed on the carrier plate 114. That is, in this embodiment, the carrier 114 is arranged on the side of the second suction cup 112 close to the inner bag transfer device 3, and when the second carrier 31 is located at the first packaging station 41, the carrier 114 is connected between the second suction cup 112 and the second carrier 31, and the part of the inner bag extending out of the second carrier 31 is supported on the carrier 114 and the second suction cup 112. Based on the above, the carrier 114 can adsorb the inner bag, and when the first suction cup 111 rises to move away from the second suction cup 112, thereby opening the bag mouth, the carrier 114 and the second suction cup 112 jointly adsorb the entire lower bag body of the inner bag, so that in addition to the bag mouth being able to be opened, the entire inner cavity of the inner bag can be opened, thereby making it easier for the subsequent first pushing mechanism 12 to push the product into the inner bag.

[0050] Furthermore, the opening mechanism 11 also includes a support module 115, the support module 115 includes two plate portions, the two plate portions are respectively a first plate portion 1151 and a second plate portion 1152, the first plate portion 1151 and the second plate portion 1152 are arranged opposite to each other in the vertical direction, specifically, the upper plate portion is used as the first plate portion 1151, and the lower plate portion is used as the second plate portion 1152, that is, the first plate portion 1151 is located above the second plate portion 1152, the support module 115 also includes a second driving member 1153, the second driving member 1153 is configured to drive the first plate portion 1151 and the second plate portion 1152 to move relative to or away from each other in the vertical direction, in addition, the opening mechanism 11 also includes a third driving member 116, the third driving member 116 is configured to drive the support module 115 to move in the horizontal direction, so that the first plate portion 1151 and the first plate portion 1151 have a first working state of extending from the bag opening into the inner bag, and a second working state of exiting the inner bag from the bag opening.

[0051] Based on the above, after the bag opening of the inner bag is opened by the first suction cup 111 and the second suction cup 112, the third driving member 116 drives the opening module 115 to move in the horizontal direction so that the first plate portion 1151 and the second plate portion 1152 extend into the inner bag from the opened bag opening. Afterwards, the second driving member 1153 drives the first plate portion 1151 and the second plate portion 1152 to move in opposite directions in the vertical direction, so that the bag opening of the inner bag can be shaped to increase the width of the bag opening, thereby making it easier for the product to enter the inner bag.

[0052] It can be understood that after the product is pushed into the inner bag, the third driving member 116 drives the opening module 115 to move horizontally, so that the first plate portion 1151 and the second plate portion 1152 exit the inner bag from the bag opening, so that the subsequent inner bag can move to the second packaging station 42 with the second carrier 31.

[0053] Exemplarily, in this embodiment, the second driving member 1153 is a bidirectional cylinder. Of course, in other optional embodiments, the second driving member 1153 may also be other linear driving structures such as a bidirectional screw slide module, and this embodiment does not impose specific restrictions on this.

[0054] In addition, illustratively, in this embodiment, the third driving member 116 can be selected as a linear driving module such as a cylinder or an electric cylinder, and this embodiment does not impose any specific limitation on this.

[0055] Based on the content mentioned above, in this embodiment, the support module 115 is installed on the first carrier 13, and the first plate portion 1151 and the second plate portion 1152 are arranged on the side of the first carrier 13 close to the first suction cup 111 and the second suction cup 112, and the third driving member 116 can drive the first carrier 13 to move in the horizontal direction, thereby driving the first carrier 13 and the support module 115 to move in the horizontal direction together.

[0056] As described above, after the third driving member 116 drives the first carrier 13 and drives the opening module 115 to move horizontally, so that the first plate portion 1151 and the second plate portion 1152 extend into the inner bag from the opened bag mouth, the first plate portion 1151 and the second plate portion 1152 move between the first suction cup 111 and the second suction cup 112, and then the second driving member 1153 can drive the first plate portion 1151 and the second plate portion 1152 to move, and make the second plate portion 1152 and the first carrier 13 move horizontally. Since the first carrier 13 moves together with the opening module 115, after the first plate portion 1151 and the second plate portion 1152 extend into the inner bag from the opened bag mouth and shape the bag mouth of the inner bag, the distance between the second plate portion 1152 and the first carrier 13 will not increase due to the horizontal movement of the opening module 115, thereby ensuring that when the first pushing mechanism 12 pushes the product, the product can smoothly transition from the first carrier 13 to the second plate portion 1152 and move into the inner bag.

[0057] Illustratively, in this embodiment, along the pushing path of the first pushing mechanism 12, the second plate portion 1152 is arranged adjacent to the first carrier 13. After the first plate portion 1151 and the second plate portion 1152 extend into the inner bag from the opened bag opening and shape the bag opening of the inner bag, the second plate portion 1152 is directly connected to the downstream side of the first carrier 13 along the pushing path of the first pushing mechanism 12, so that the product can be directly transferred to the second plate portion 1152 after leaving the first carrier 13, and then the product can be smoothly pushed into the inner bag.

[0058] Based on the above, in the present embodiment, the second suction cup 112 is slightly lower than the first carrier 13, the first driving member 113 can drive the first suction cup 111 to move toward or away from the second suction cup 112 in the vertical direction, so as to open the bag opening of the inner bag, the third driving member 116 can drive the first plate portion 1151 and the second plate portion 1152 to extend into the inner bag after the bag opening is opened, the second driving member 1153 can drive the first plate portion 1151 and the second plate portion 1152 to move until the first plate portion 1151 abuts against the side of the first suction cup 111 facing the second suction cup 112, and at the same time, the second plate portion 1152 abuts against the side of the second suction cup 112 facing the first suction cup 111, and the second plate portion 1152 is flush with the first carrier 13, and then, the first pushing mechanism 12 can push the product to transfer the product from the first carrier 13 to the inner bag.

[0059] Among them, the first pushing mechanism 12 includes a first pushing plate 121 and a fourth driving member 122. The fourth driving member 122 is configured to drive the first pushing plate 121 to move in a horizontal direction so that the first pushing plate 121 can push the product into the inner bag. Exemplarily, in this embodiment, the moving direction of the first pushing plate 121 is the same as the moving direction of the first carrier 13.

[0060] Exemplarily, the fourth driving member 122 may be a linear driving structure such as a pneumatic cylinder or an electric cylinder, and this embodiment does not impose any specific limitation on this.

[0061] Based on the content mentioned above, after the product is transferred from the first carrier 13 to the inner bag, the first push plate 121 is reset, the first carrier 13 and the support module 115 are reset, and then, the first suction cup 111 is reset, and the first suction cup 111, the second suction cup 112 and the carrier plate 114 are all released from adsorption, and the second carrier 31 drives the inner bag to move from the first packaging station 41 to the second packaging station 42.

[0062] Furthermore, in the present embodiment, the folding mechanism 21 includes a pressure rod 211 and a stopper 212. The pressure rod 211 can be raised and lowered in the vertical direction to press the inner bag after the second carrier 31 moves to the second packaging station 42, and the pressing portion is adjacent to the opening 311 arranged on the second carrier 31. A transfer channel 2121 is provided through the interior of the stopper 212, that is, the side wall 2122, the bottom 2123 and the top 2124 of the stopper 212 form the transfer channel 2121. The stopper 212 can be raised and lowered in the vertical direction so that the stopper 212 has a first working position in which the transfer channel 2121 is connected to the opening 311, and a second working position away from the opening 311. Specifically, the folding mechanism 21 also includes a fifth driving member 213, which is used to drive the stopper 212 to rise and fall in the vertical direction.

[0063] Exemplarily, the fifth driving member 213 may be a linear driving structure such as a pneumatic cylinder or an electric cylinder, and this embodiment does not impose any specific limitation on this.

[0064] As shown above, when the second carrier 31 moves to the second packaging station 42, the stopper 212 is located at the second working position and is located below the portion of the inner bag extending from the second carrier 31. Then, the pressing rod 211 is pressed down and the stopper 212 is raised, thereby folding the portion of the inner bag adjacent to the bag opening upward. Then, the pressing rod 211 is raised and moves away from the inner bag. Since the raised stopper 212 can stop the folded portion of the inner bag, the folded portion of the inner bag will not be reset after the pressing rod 211 is raised. The mechanism 22 pushes the inner bag to enter the transfer channel 2121. Under the stopping action of the top 2124 of the block 212, when the inner bag enters the transfer channel 2121, the folded portion of the inner bag flips toward the side of the inner bag away from the bag opening. From above, in this embodiment, the inner bag entering the transfer channel 2121 is in a state where the portion adjacent to the bag opening is folded upward and close to the side of the inner bag away from the bag opening. Therefore, the inner bag that passes through the transfer channel 2121 and moves into the outer packaging body is in a closed state.

[0065] It can be understood that the product packaging equipment also includes a third carrier (not shown in the figure), which is used to carry the outer packaging body. The third carrier is provided with a fixing structure such as a clamp that can be used to fix the outer packaging body. It is worth noting that the specific structure of the third carrier is the existing technology, so this embodiment will not be elaborated on it.

[0066] In addition, it is worth mentioning that in this embodiment, while the pressure rod 211 descends in the vertical direction, it can also move along the extension direction of the transfer channel 2121 toward the side close to the stopper 212, thereby making it easier to fold the portion of the inner bag adjacent to the bag opening upward.

[0067] Based on the above, in the present embodiment, the folding mechanism 21 also includes a sixth driving member 214, which is used to drive the pressure rod 211 to move in the vertical direction and the extension direction of the transfer channel 2121. By way of example, in the present embodiment, the sixth driving member 214 is a linear driving structure such as a cylinder or an electric cylinder, and the sixth driving member 214 is tilted so as to be able to drive the pressure rod 211 to move in the vertical direction and the extension direction of the transfer channel 2121 at the same time. Of course, in other optional embodiments, the sixth driving member 214 may also be composed of two linear driving structures, one of which is used to drive the pressure rod 211 to move in the vertical direction, and the other linear driving structure is used to drive the pressure rod 211 to move in the extension direction of the transfer channel 2121. This embodiment does not impose any specific restrictions on this.

[0068] In addition, the folding mechanism 21 further includes a seventh driving member 215 , which is used to drive the pressing rod 211 to move in the horizontal direction, so that after the second platform 31 moves to the second packaging station 42 , the pressing rod 211 can move to just above the inner bag.

[0069] Exemplarily, the seventh driving member 215 may be a linear driving structure such as a pneumatic cylinder or an electric cylinder, and this embodiment does not impose any specific limitation on this.

[0070] Furthermore, the second pushing mechanism 22 includes a second push plate 221 and an eighth driving member 222. The eighth driving member 222 is configured to drive the second push plate 221 to move in a horizontal direction so that the second push plate 221 can push the inner bag into the outer packaging body. In this embodiment, the moving direction of the second push plate 221 is the same as the extension direction of the transfer channel 2121.

[0071] Exemplarily, the eighth driving member 222 may be a linear driving structure such as a pneumatic cylinder or an electric cylinder, and this embodiment does not impose any specific limitation on this.

[0072] In addition, in this embodiment, the cross-sectional area of ​​the transfer channel 2121 gradually decreases from the side close to the second pushing mechanism 22 to the side away from the second pushing mechanism 22, thereby ensuring that the inner bag placed on the second platform 31 can be pushed into the transfer channel 2121 more smoothly, and after the inner bag enters the transfer channel 2121, the channel wall of the transfer channel 2121 can guide the inner bag, thereby ensuring that the inner bag can accurately enter the outer packaging body.

[0073] Furthermore, based on the above, in the present embodiment, the product packaging equipment further includes a turntable 32, on which four second platforms 31 are arranged, the four second platforms 31 are evenly arranged around the axis of the turntable 32, the first packaging station 41 and the second packaging station 42 are arranged at intervals along the circumference of the turntable 32, and the turntable 32 can rotate around its axis so that the four second platforms 31 can all move to the first packaging station 41 and the second packaging station 42 in sequence, and, for two adjacent second platforms 31, when the second platform 31 located on the upstream side moves to the second packaging station 42, the second platform 31 located on the downstream side moves to the first packaging station 41. It can be understood that an inner bag loading station 43 is also provided between the first packaging station 41 and the second packaging station 42, the four second platforms 31 can move to the inner bag loading station 43 in sequence, and perform inner bag loading operations at the inner bag loading station 43.

[0074] From the above, after each rotation of the turntable 32 by a preset angle, the first packaging station 41, the second packaging station 42 and the inner bag loading station 43 each have a second carrier 31, wherein the preset angle is equal to 360° divided by the number of the second carriers 31, and in this embodiment, the preset angle is 45°. Specifically, after the turntable 32 rotates once, the second carrier 31 originally at the first packaging station 41 can be transferred to the second packaging station 42, the second carrier 31 originally at the second packaging station 42 can be transferred to the inner bag loading station 43, and the second carrier 31 originally at the inner bag loading station 43 is transferred between the inner bag loading station 43 and the first packaging station 41, and is transferred to the first packaging station 41 after the turntable 32 rotates next time. Alternatively, after the turntable 32 rotates once, the second carrier 31 originally at the first packaging station 41 can be transferred to the second packaging station 42, the second carrier 31 originally at the inner bag loading station 43 is transferred to the first packaging station 41, and the second carrier 31 originally at the second packaging station 42 can be transferred between the second packaging station 42 and the inner bag loading station 43, and transferred to the inner bag loading station 43 after the turntable 32 rotates next time.

[0075] As described above, this embodiment can shorten the production cycle, thereby further improving the production efficiency of the product.

[0076] It is understandable that in other optional embodiments, the turntable 32 can also be configured to have three or more second carriers 31. The specific number of the second carriers 31 is determined based on the actual production rhythm required. It is only necessary to ensure that after each rotation of the turntable 32, the first packaging station 41, the second packaging station 42 and the inner bag loading station 43 all have a second carrier 31. This embodiment does not impose specific restrictions on this.

[0077] Based on the above, the opening mechanism 11 and the folding mechanism 21 are both arranged on the outer periphery of the turntable 32, and the opening 311 of the second carrier 31 is opened along the radial direction of the turntable 32, and is located on the side of the second carrier 31 away from the axis of the turntable 32 along the radial direction of the turntable 32, that is, the part of the inner bag adjacent to the bag opening extends out of the turntable 32, so that when the inner bag is transferred to the first packaging station 41, the opening mechanism 11 can open the bag opening of the inner bag, and when the inner bag is transferred to the second packaging station 42, the folding mechanism 21 can fold the inner bag.

[0078] In addition, in the present embodiment, the first packaging device 1 also includes a first shaping mechanism 14, which is arranged on the side of the opening mechanism 11 away from the first pushing mechanism 12, and includes a first clamp 141, a second clamp 142 and a first driving unit 143. The first driving unit 143 is configured to drive the first clamp 141 and the second clamp 142 to move, so that the first clamp 141 and the second clamp 142 can be surrounded by the outer periphery of the side of the inner bag away from the bag opening, so that when the first plate portion 1151 and the second plate portion 1152 open the bag opening of the inner bag, the side of the inner bag away from the bag opening can be shaped, thereby making it more convenient for the product to enter the inner bag.

[0079] Correspondingly, the second packaging device 2 also includes a second shaping mechanism 23, which is arranged on the side of the folding mechanism 21 close to the second pushing mechanism 22, and includes a third clamp 231, a fourth clamp 232 and a second driving unit 233. The second driving unit 233 is configured to drive the third clamp 231 and the fourth clamp 232 to move, so that the third clamp 231 and the fourth clamp 232 can be surrounded by the outer periphery of the side of the inner bag away from the bag opening, so that the inner bag can be shaped when the second carrier 31 moves to the second packaging station 42, thereby making it more convenient to push the inner bag into the transfer channel 2121.

[0080] It is understandable that the first driving part 143 and the second driving part 233 are both clamping claw cylinders. Since the specific structures of the first driving part 143 and the second driving part 233 are both existing technologies, this embodiment will not be described in detail.

[0081] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
