In addition, the terms "first" and "second" are only used to distinguish in description and have no special meaning.

[0040] Referring to Figures 1 to 8 , the present embodiment provides a product packaging device, which comprises a first packaging device 1 and a second packaging device 2, wherein the first packaging device 1 comprises an opening mechanism 11 configured to open the bag opening of the inner bag and a first pushing mechanism 12 configured to push the product into the inner bag from the bag opening, and the second packaging device 2 comprises a folding mechanism 21 configured to fold the part of the inner bag adjacent to the bag opening upward and close to the side of the inner bag away from the bag opening, and a second pushing mechanism 22 configured to push the folded inner bag into the outer packaging body.

[0041] Based on the above, the present embodiment realizes the automatic packaging of the product 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, the present embodiment can seal the inner bag during the packaging process, thereby preventing the subsequent product from sliding out of the inner bag during transportation, thereby on the one hand avoiding the influence on the shopping experience of consumers due to the exposure of the product from the inner bag, and on the other hand ensuring that the inner bag can always protect the product to prevent the product from being damaged due to collision during transportation.

[0042] Exemplarily, the present embodiment takes the product as a mouse and the outer packaging body as a packaging box as an example for illustration, the first packaging device 1 first packs the mouse into the inner bag, specifically, the opening mechanism 11 is used to open the bag opening of the inner bag, and the first pushing mechanism 12 is used to push the mouse into the inner bag from the opened bag opening, and the second packaging device 2 then packs the inner bag containing the mouse into the packaging box, specifically, the folding mechanism 21 first folds the inner bag containing the mouse to fold the part of the inner bag adjacent to the bag opening upward and close to the side of the inner bag away from the bag opening, thereby sealing the mouse in the inner bag, and the second pushing mechanism 22 then 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 further comprises a first carrier 13 configured to carry the product, and the second packaging device 2 is arranged at the second packaging station 42, and the product packaging apparatus further comprises an inner bag transferring device 3 comprising a second carrier 31, the inner bag can be carried on the second carrier 31, and the second carrier 31 can be moved to the first packaging station 41 and the second packaging station 42 in turn, so that the inner bag can be located at the first packaging station 41 and the second packaging station 42 in turn.

[0044] When the inner bag is located at the first packaging station 41, the opening mechanism 11 opens the bag opening of the inner bag, the first pushing mechanism 12 pushes the product carried on the first carrier 13 into the inner bag through the opened bag opening, and then the second carrier 31 moves to the second packaging station 42, the folding mechanism 21 folds the inner bag to enclose 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 comprises two suction cups, specifically, the two suction cups are 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 in the vertical direction, specifically, the upper suction cup is the first suction cup 111, and the lower suction cup is 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 further comprises a first driving member 113 configured to drive the first suction cup 111 to move in the vertical direction, when the inner bag is located at the first packaging station 41, the part of the lower layer bag body of the inner bag adjacent to the bag opening is supported on the second suction cup 112, the second suction cup 112 can adsorb the part of the lower layer bag body of the inner bag adjacent to the bag opening, 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 part of the upper layer bag body of the inner bag adjacent to the bag opening, then the first driving member 113 drives the first suction cup 111 to ascend in the vertical direction, so as to be away from the second suction cup 112, thereby opening the bag opening of the inner bag.

[0046] Exemplarily, the first driving member 113 can be a linear driving structure such as a pneumatic cylinder or an electric cylinder, and the present embodiment does not make specific limitation thereto.

[0047] It can be understood that in other optional embodiments, the first driving member 113 can also be configured to drive the first suction disc 111 and the second suction disc 112 to move together in the vertical direction, or the first driving member 113 can also be configured to drive only the second suction disc 112 to move in the vertical direction, and the present embodiment does not make specific limitation in this regard. Specifically, for the first driving member 113 configured to drive the first suction disc 111 and the second suction disc 112 to move together in the vertical direction, the first driving member 113 can drive the first suction disc 111 and the second suction disc 112 to move relatively or oppositely in the vertical direction, when the inner bag is located at the first packaging station 41, the part of the inner bag adjacent to the bag opening can be located between the first suction disc 111 and the second suction disc 112, the first driving member 113 drives the first suction disc 111 and the second suction disc 112 to move relatively in the vertical direction, so that the first suction disc 111 can adsorb the part of the upper bag body of the inner bag adjacent to the bag opening, and the second suction disc 112 can adsorb the part of the lower bag body of the inner bag adjacent to the bag opening, then the first driving member 113 drives the first suction disc 111 and the second suction disc 112 to move oppositely in the vertical direction, so as to open the bag opening of the inner bag. For the first driving member 113 configured to drive only the second suction disc 112 to move in the vertical direction, when the inner bag is located at the first packaging station 41, the part of the upper bag body of the inner bag adjacent to the bag opening is attached to the first suction disc 111, the first suction disc 111 can adsorb the part of the upper bag body of the inner bag adjacent to the bag opening, the first driving member 113 drives the second suction disc 112 to move upward in the vertical direction, so that the second suction disc 112 can adsorb the part of the lower bag body of the inner bag adjacent to the bag opening, then the first driving member 113 drives the second suction disc 112 to move downward in the vertical direction, so as to be away from the first suction disc 111, thereby opening the bag opening of the inner bag.

[0048] In addition, it is worth noting that in the present embodiment, the second carrier 31 is provided with an opening 311 on one side, and the part 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 part of the inner bag extending out of the second carrier 31 can be located between the first suction disc 111 and the second suction disc 112.

[0049] In addition to the first suction cup 111 and the second suction cup 112, the opening mechanism 11 further comprises a carrier plate 114, and the carrier plate 114 is provided with a suction hole 1141. It can be understood that the suction hole 1141 is in communication with a vacuum generator (not shown in the figure), so that a negative pressure environment can be formed in the suction hole 1141. When the inner bag is located at the first packaging station 41, the part of the inner bag adjacent to the first suction cup 111 and the second suction cup 112 is placed on the carrier plate 114. That is, in the embodiment, the carrier plate 114 is arranged on the side of the second suction cup 112 close to the inner bag transfer device 3. When the second carrier 31 is located at the first packaging station 41, the carrier plate 114 is connected between the second suction cup 112 and the second carrier 31. The part of the inner bag extending out of the second carrier 31 is supported on the carrier plate 114 and the second suction cup 112. Based on the above, the carrier plate 114 can adsorb the inner bag. During the process that the first suction cup 111 rises to move away from the second suction cup 112, the carrier plate 114 and the second suction cup 112 adsorb the entire lower bag body of the inner bag together, so that the entire inner cavity of the inner bag can be opened in addition to the bag opening being opened, thereby facilitating the subsequent product pushing of the first pushing mechanism 12 into the inner bag.

[0050] Further, the opening mechanism 11 further comprises a bag opening supporting module 115. The bag opening supporting module 115 comprises two plate parts, which are a first plate part 1151 and a second plate part 1152. The first plate part 1151 and the second plate part 1152 are oppositely arranged along the vertical direction. Specifically, the upper plate part is the first plate part 1151, and the lower plate part is the second plate part 1152. That is, the first plate part 1151 is located above the second plate part 1152. The bag opening supporting module 115 further comprises a second driving member 1153 configured to drive the first plate part 1151 and the second plate part 1152 to move oppositely or away from each other along the vertical direction. In addition, the opening mechanism 11 further comprises a third driving member 116 configured to drive the bag opening supporting module 115 to move along the horizontal direction, so that the first plate part 1151 and the first plate part 1151 have a first working state in which the bag opening extends into the inner bag, and a second working state in which the bag opening exits the inner bag.

[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 bag opening supporting module 115 to move along the horizontal direction, so that the first plate part 1151 and the second plate part 1152 extend into the inner bag from the opened bag opening. Then, the second driving member 1153 drives the first plate part 1151 and the second plate part 1152 to move away from each other along the vertical direction, so as to shape the bag opening of the inner bag to increase the width of the bag opening, thereby facilitating 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 mouth supporting module 115 to move in the horizontal direction, so that the first plate part 1151 and the second plate part 1152 are withdrawn from the inner bag through the bag opening, so that the subsequent inner bag can be moved to the second packaging station 42 along with the second carrier 31.

[0053] Exemplarily, in the embodiment, the second driving member 1153 is a bidirectional air cylinder, of course, in other optional embodiments, the second driving member 1153 can also be a bidirectional screw rod sliding table module or other linear driving structure, and the embodiment does not make specific limitation hereon.

[0054] In addition, exemplarily, in the embodiment, the third driving member 116 can be selected from a linear driving module such as an air cylinder or an electric cylinder, and the embodiment does not make specific limitation hereon.

[0055] Based on the foregoing, in the embodiment, the mouth supporting module 115 is installed on the first carrier 13, and the first plate part 1151 and the second plate part 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, so as to drive the first carrier 13 and the mouth supporting module 115 to move in the horizontal direction together.

[0056] From the above, after the third driving member 116 drives the first carrier 13 and the mouth supporting module 115 to move in the horizontal direction together, so that the first plate part 1151 and the second plate part 1152 are inserted into the inner bag through the opened bag opening, the first plate part 1151 and the second plate part 1152 are moved between the first suction cup 111 and the second suction cup 112, and then the second driving member 1153 can drive the first plate part 1151 and the second plate part 1152 to move, so that the second plate part 1152 is flush with the first carrier 13. Since the first carrier 13 moves together with the mouth supporting module 115, after the first plate part 1151 and the second plate part 1152 are inserted into the inner bag through the opened bag opening and shape the bag opening of the inner bag, the distance between the second plate part 1152 and the first carrier 13 will not increase due to the movement of the mouth supporting module 115 in the horizontal direction, so as to ensure that when the product is pushed by the first pushing mechanism 12, the product can be smoothly transferred from the first carrier 13 to the second plate part 1152 and moved into the inner bag.

[0057] Exemplarily, in the embodiment, along the pushing path of the first pushing mechanism 12, the second plate part 1152 is arranged adjacent to the first carrier 13, and after the first plate part 1151 and the second plate part 1152 are inserted into the inner bag through the opened bag opening and shape the bag opening of the inner bag, the second plate part 1152 is directly connected on 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 part 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 disc 112 is slightly lower than the first carrier 13, the first driving member 113 is capable of driving the first suction disc 111 to move along the vertical direction towards or away from the second suction disc 112, so as to open the bag opening of the inner bag, the third driving member 116 is capable of driving the first plate part 1151 and the second plate part 1152 to extend into the inner bag after the bag opening is opened, and the second driving member 1153 is capable of driving the first plate part 1151 and the second plate part 1152 to move until the first plate part 1151 abuts to the side of the first suction disc 111 facing the second suction disc 112, while the second plate part 1152 abuts to the side of the second suction disc 112 facing the first suction disc 111, and the second plate part 1152 is flush with the first carrier 13, and then the first pushing mechanism 12 is capable of pushing the product to transfer the product from the first carrier 13 to the inner bag.

[0059] In the present embodiment, the first pushing mechanism 12 comprises a first pushing plate 121 and a fourth driving member 122, and the fourth driving member 122 is configured to drive the first pushing plate 121 to move along the horizontal direction, so as to enable the first pushing plate 121 to push the product into the inner bag. For example, in the present embodiment, the moving direction of the first pushing plate 121 is the same as the moving direction of the first carrier 13.

[0060] For example, the fourth driving member 122 can be a linear driving structure such as a pneumatic cylinder or an electric cylinder, and the present embodiment does not make specific limitation thereto.

[0061] Based on the above, after the product is transferred from the first carrier 13 to the inner bag, the first pushing plate 121 is reset, the first carrier 13 and the bag opening module 115 are reset, then the first suction disc 111 is reset, and the first suction disc 111, the second suction disc 112 and the carrier plate 114 are all released from the 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] Further, in the present embodiment, the folding mechanism 21 comprises a pressing rod 211 and a blocking block 212, the pressing rod 211 is capable of lifting along the vertical direction to press the inner bag after the second carrier 31 moves to the second packaging station 42, and the pressing position is adjacent to the opening 311 arranged on the second carrier 31, and the blocking block 212 has a transfer channel 2121 passing through the inside, i.e., the side wall 2122, the bottom 2123 and the top 2124 of the blocking block 212 are configured to form the transfer channel 2121, and the blocking block 212 is capable of lifting along the vertical direction, so as to enable the blocking block 212 to have a first working position in which the transfer channel 2121 is in abutment with the opening 311, and a second working position away from the opening 311. Specifically, the folding mechanism 21 further comprises a fifth driving member 213 for driving the blocking block 212 to lift along the vertical direction.

[0063] Exemplarily, the fifth driving member 213 can be a linear driving structure such as a pneumatic cylinder or an electric cylinder, and the present embodiment is not limited in this regard.

[0064] As described above, when the second carrier 31 moves to the second packaging station 42, the stopper 212 is located at the second working position and below the part of the inner bag that extends out of the second carrier 31. Then, the pressing rod 211 is pressed down, and the stopper 212 is lifted up, so as to fold the part of the inner bag adjacent to the bag opening upward. Then, the pressing rod 211 is lifted up and away from the inner bag. Since the lifted stopper 212 can stop the folded part of the inner bag, the folded part of the inner bag will not be reset after the pressing rod 211 is lifted up. Then, the second pushing mechanism 22 pushes the inner bag, so as to make the inner bag enter the transfer channel 2121. Under the stopping effect of the top 2124 of the stopper 212, when the inner bag enters the transfer channel 2121, the folded part of the inner bag turns to the side of the inner bag away from the bag opening. As described above, in the present embodiment, the inner bag entering the transfer channel 2121 is in a state that the part adjacent to the bag opening is folded upward and close to the side of the inner bag away from the bag opening. Thus, the inner bag moving into the outer packaging body through the transfer channel 2121 is in a closed state.

[0065] It can be understood that the product packaging apparatus further comprises a third carrier (not shown in the figure), which is used for carrying the outer packaging body. The third carrier is provided with a fixing structure such as a clamping jaw, which can be used for fixing the outer packaging body. It is worth noting that the specific structure of the third carrier is a prior art, and thus the present embodiment will not be described here.

[0066] In addition, it is worth noting that in the present embodiment, the pressing rod 211 can move to the side close to the stopper 212 along the extension direction of the transfer channel 2121 while being lowered in the vertical direction, so as to facilitate the folding of the part of the inner bag adjacent to the bag opening upward.

[0067] Based on the above, in the present embodiment, the folding mechanism 21 further comprises a sixth driving member 214, which is used for driving the pressing rod 211 to move in the vertical direction and the extension direction of the transfer channel 2121. Exemplarily, in the present embodiment, the sixth driving member 214 is a linear driving structure such as a pneumatic cylinder or an electric cylinder. The sixth driving member 214 is inclinedly arranged, so as to drive the pressing 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 alternative embodiments, the sixth driving member 214 can also be composed of two linear driving structures. One of the linear driving structures is used for driving the pressing rod 211 to move in the vertical direction, and the other linear driving structure is used for driving the pressing rod 211 to move in the extension direction of the transfer channel 2121. The present embodiment is not limited in this regard.

[0068] In addition, the folding mechanism 21 further comprises a seventh driving member 215 configured to drive the pressing rod 211 to move in the horizontal direction, so that the pressing rod 211 can move to the top of the inner bag after the second carrier 31 moves to the second packaging station 42.

[0069] Illustratively, the seventh driving member 215 can be a linear driving structure such as a pneumatic cylinder or an electric cylinder, and the present embodiment does not make specific limitation in this regard.

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

[0071] Illustratively, the eighth driving member 222 can be a linear driving structure such as a pneumatic cylinder or an electric cylinder, and the present embodiment does not make specific limitation in this regard.

[0072] In addition, in the present 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, so as to ensure that the inner bag placed on the second carrier 31 can be more smoothly pushed into the transfer channel 2121, and after the inner bag enters the transfer channel 2121, the channel wall of the transfer channel 2121 can guide the inner bag, so as to ensure that the inner bag can accurately enter the outer packaging body.

[0073] Further, based on the above, in the present embodiment, the product packaging apparatus further comprises a turntable 32, four second carriers 31 are arranged on the turntable 32, the four second carriers 31 are uniformly arranged around the axis of the turntable 32, the first packaging station 41 and the second packaging station 42 are arranged along the circumference of the turntable 32, and the turntable 32 can rotate around its axis, so that the four second carriers 31 can move to the first packaging station 41 and the second packaging station 42 in turn. In addition, for the two adjacent second carriers 31, when the second carrier 31 on the upstream side moves to the second packaging station 42, the second carrier 31 on the downstream side moves to the first packaging station 41. It can be understood that the first packaging station 41 and the second packaging station 42 are further provided with an inner bag loading station 43, and the four second carriers 31 can move to the inner bag loading station 43 in turn and perform the inner bag loading operation at the inner bag loading station 43.

[0074] From the above, after the rotating disc 32 rotates 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 the embodiment, the preset angle is 45°. Specifically, after the rotating disc 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 to between the inner bag loading station 43 and the first packaging station 41, and is transferred to the first packaging station 41 after the rotating disc 32 rotates next time. Alternatively, after the rotating disc 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 to between the second packaging station 42 and the inner bag loading station 43, and is transferred to the inner bag loading station 43 after the rotating disc 32 rotates next time.

[0075] From the above, the embodiment can shorten the production rhythm, thereby further improving the production efficiency of the product.

[0076] It can be understood that in other alternative embodiments, the rotating disc 32 can also be provided with three or more than five second carriers 31, and the specific number of the second carriers 31 is determined according to the actual required production rhythm, as long as the first packaging station 41, the second packaging station 42 and the inner bag loading station 43 each have a second carrier 31 after the rotating disc 32 rotates once, and the embodiment does not make specific limitation.

[0077] Based on the above, the opening mechanism 11 and the folding mechanism 21 are each arranged at the outer periphery of the rotating disc 32, and the opening 311 of the second carrier 31 is arranged along the radial direction of the rotating disc 32 and is located at the side of the second carrier 31 away from the axis of the rotating disc 32 along the radial direction of the rotating disc 32, i.e., the part of the inner bag adjacent to the bag opening extends from the rotating disc 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 embodiment, the first packaging device 1 further comprises a first shaping mechanism 14, which is arranged on the side of the opening mechanism 11 away from the first pushing mechanism 12, and comprises a first clamping hoop 141, a second clamping hoop 142 and a first driving part 143, the first driving part 143 is configured to drive the first clamping hoop 141 and the second clamping hoop 142 to move, so that the first clamping hoop 141 and the second clamping hoop 142 can enclose the outer periphery of the side of the inner bag away from the bag opening, thereby being able to shape the side of the inner bag away from the bag opening when the first plate part 1151 and the second plate part 1152 prop open the bag opening of the inner bag, thereby making it more convenient for the product to enter the inner bag.

[0079] Correspondingly, the second packaging device 2 further comprises a second shaping mechanism 23, which is arranged on the side of the folding mechanism 21 close to the second pushing mechanism 22, and comprises a third clamping hoop 231, a fourth clamping hoop 232 and a second driving part 233, the second driving part 233 is configured to drive the third clamping hoop 231 and the fourth clamping hoop 232 to move, so that the third clamping hoop 231 and the fourth clamping hoop 232 can enclose the outer periphery of the side of the inner bag away from the bag opening, thereby being able to shape the inner bag 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 can be understood that the first driving part 143 and the second driving part 233 are both clamping jaw cylinders, and since the specific structures of the first driving part 143 and the second driving part 233 are prior art, this embodiment will not be described here.
