The second curved arc body 1133 may be located on one side of the second bag opening support body 1131 deviating from the second bag opening supporting piece 30, so as to help avoid occupying the spatial position of the second bag opening support body 1131 facing one side of the second bag opening supporting piece 30, so that in the process that subsequent materials enter the packaging bag 500 from the space between the first bag opening supporting piece 10 and the second bag opening supporting piece 30, blocking caused by the process of putting the materials into the bag is avoided.
Second props a bag piece 30 and includes second sack supporting part 31 and second sack and draws portion 33, and second sack supporting part 31 and second sack are drawn portion 33 and are connected, and second sack supporting part 31 is suitable for supporting sack 501 of wrapping bag 500, and second sack is drawn portion 33 and is suitable for tearing the sack 501 of wrapping bag 500 flat. The second bag-mouth support portion 31 may be a sheet metal part or a cast part.
The second pocket support 31 may include a third pocket support panel 311 and a fourth pocket support panel 313, and the third pocket support panel 311 and the fourth pocket support panel 313 may be inserted into the pouch 500 under the driving of the driving assembly 50 to support the pocket 501 of the pouch 500. The third pocket support plate 311 is connected to the fourth pocket support plate 313, for example, the fourth pocket support plate 313 may be connected to the third pocket support plate 311 at an angle, and the fourth pocket support plate 313 may be inclined toward the first pocket supporting member 10 with respect to the third pocket support plate 311, so that after the third pocket support plate 311 and the fourth pocket support plate 313 support the pocket 501 of the packing bag 500 together, the shape of the pocket 501 of the packing bag 500 is more suitable for loading of the material.
Third sack backup pad 311 may include third sack support body 3111 and third curved-arc body 3113, and third sack support body 3111 is connected with third curved-arc body 3113, for example third curved-arc body 3113 may connect in the edge that third sack support body 3111 deviates from fourth sack backup pad 313, and so, third curved-arc body 3113 helps to avoid third sack support body 3111 to deviate from the edge of fourth sack backup pad 313 and wrapping bag 500 because direct contact punctures wrapping bag 500 or causes obvious scratch to wrapping bag 500.
Third curved arc 3113 can be located third sack and support body 3111 and deviate from one side of first bag piece 10 to help avoiding occupying the spatial position that third sack supported body 3111 faced one side of first bag piece 10, so follow-up material and prop the in-process that the interval between bag piece 30 gets into wrapping bag 500 from first bag piece 10 and second, avoided the process of going into the bag to the material to cause and block.

Fourth curved arc 3133 may be located on a side of fourth pocket support body 3131 facing away from first pocket supporting member 10, so as to help avoid occupying a spatial position of fourth pocket support body 3131 facing a side of first pocket supporting member 10, thereby avoiding blocking a process of feeding a material into pocket during a process of feeding a subsequent material into packaging bag 500 from a space between first pocket supporting member 10 and second pocket supporting member 30.
Second mouth pull 33 may be driven by drive assembly 50 to extend into bag 500 to flatten mouth 501 of bag 500. The second pocket pull portion 33 may be attached to the second pocket support 31, for example, the second pocket pull portion 33 may be attached to the third pocket support panel 311. The second pocket pulling portion 33 may be elongated, and the second pocket pulling portion 33 may extend in a direction away from the second pocket support portion 31. Because the fourth pocket support panel 313 is inclined relative to the third pocket support panel 311 in the direction of the first pocket member 10, the connection of the second pocket pulling portion 33 to the third pocket support panel 311 is more conducive to leveling the pocket 501 of the package 500 than the connection of the fourth pocket support panel 313.
Because the driving assembly 50 can drive the first bag opening member 10 and the second bag opening member 30 to selectively approach or separate from each other, after the bag opening 501 of the packaging bag 500 is opened, the driving assembly 50 can drive the first bag opening member 10 and the second bag opening member 30 to approach each other, so that the arrangement between the first bag opening member 10 and the second bag opening member 30 is compact, and the subsequent driving assembly 50 can drive the first bag opening member 10 and the second bag opening member 30 to extend into the packaging bag 500 from the bag opening 501 of the packaging bag 500 more easily.
In addition, after the first bag opening member 10 and the second bag opening member 30 are located in the packaging bag 500, the driving assembly 50 can drive the first bag opening member 10 and the second bag opening member 30 located in the packaging bag 500 to be away from each other, so that the first bag opening supporting portion 11 of the first bag opening member 10 and the second bag opening supporting portion 31 of the second bag opening member 30 support the bag opening 501 of the packaging bag 500, and the problem that the bag opening cannot be stably kept in an unfolded shape due to the fact that the packaging bag 500 is soft is avoided; and because the first bag opening member 10 and the second bag opening member 30 are far away from each other, the distance between the first bag opening member 10 and the second bag opening member 30 is larger, which is helpful for the material to enter the packaging bag 500 from the distance between the first bag opening member 10 and the second bag opening member 30, and reduces the blocking influence on the material entering process.
Since the driving assembly 50 can also drive the first bag opening member 10 and the second bag opening member 30 to selectively extend into or out of the packaging bag 500, in this process, the driving assembly 50 can drive the first bag opening member 10 and the second bag opening member 30 to move to different positions. Wherein, the position can include that the sack supports the position, the sack drags position and wrapping bag detached position, and the sack drags the position and can be located between wrapping bag detached position and the sack supported position, can be for the direction of dragging portion 13 from first sack supporting part 11 to first sack from wrapping bag detached position to the direction of sack supported position, perhaps, can be for the direction of dragging portion 33 from second sack supporting part 31 to the second sack from wrapping bag detached position to the direction of sack supported position.
When the driving assembly 50 drives the first bag opening member 10 and the second bag opening member 30 to move from the separated position of the packing bag to the bag opening supporting position, the first bag opening member 10 and the second bag opening member 30 extend into the packing bag 500, and the first bag opening supporting portion 11 and the second bag opening supporting portion 31 can support the bag opening 501 of the packing bag 500, at this time, the bag opening 501 of the packing bag 500 is stably maintained in the unfolded shape, and materials can be easily loaded into the packing bag 500.
After the material is loaded into the packing bag 500, the driving assembly 50 may further drive the first bag supporting member 10 and the second bag supporting member 30 to move from the bag opening supporting position to the bag opening pulling position. In this process, the driving assembly 50 can drive the first bag opening supporting portion 11 of the first bag supporting member 10 and the second bag opening supporting portion 31 of the second bag supporting member 30 to exit from the packaging bag 500, and keeps the first bag opening pulling portion 13 and the second bag opening pulling portion 33 to be located in the packaging bag 500, so that the first bag opening pulling portion 13 and the second bag opening pulling portion 33 can pull the bag opening 501 of the packaging bag 500 flat.
In addition, the position can also comprise a bag opening heat sealing position, and the bag opening heat sealing position can be positioned between the bag opening supporting position and the bag opening pulling position. After the first bag supporting member 10 and the second bag supporting member 30 support the bag opening 501 of the packaging bag 500, and before the first bag supporting member 10 and the second bag supporting member 30 move to the bag opening pulling position, the driving component 50 can also drive the first bag supporting member 10 and the second bag supporting member 30 to move from the bag opening supporting position to the bag opening heat sealing position.
In the process that the first bag opening supporting part 10 and the second bag opening supporting part 30 move to the bag opening heat-sealing positions, because the first bag opening supporting part 11 and the second bag opening supporting part 31 are always located in the packaging bag 500, and the contact areas of the first bag opening supporting part 11 and the second bag opening supporting part 31 with the packaging bag 500 are large, the friction force between the bag opening mechanism 100 and the packaging bag 500 is also large, the first bag opening supporting part 10 and the second bag opening supporting part 30 moving from the bag opening supporting positions to the bag opening heat-sealing positions can drive the packaging bag 500 to move under the action of friction force, so that the bag opening 501 of the packaging bag 500 is subjected to heat-sealing by the hot melting machine after the first bag opening pulling part 13 and the second bag opening pulling part 33 tear the bag opening 501 of the packaging bag 500 flat, and the condition that the bag opening 501 of the packaging bag 500 subjected to heat-sealing is not prone to wrinkle is facilitated.
As shown in fig. 2, in order to enable the driving component 50 to drive the first bag supporting component 10 and the second bag supporting component 30 to approach each other, move away from each other, and move to the bag opening supporting position, the bag opening heat sealing position, the bag opening pulling position, the bag opening separating position, and the like, the driving component 50 may include a first driving component 51 and a second driving component 53, the first bag supporting component 10 and the second bag supporting component 30 may be installed on the first driving component 51, and the first driving component 51 may drive the first bag supporting component 10 and the second bag supporting component 30 to approach each other, move away from each other, and the like. The first driving assembly 51 can be installed on the second driving assembly 53, and the second driving assembly 53 can drive the first driving assembly 51 to move, so that the first bag supporting member 10 and the second bag supporting member 30 move to the bag opening supporting position, the bag opening heat sealing position, the bag opening pulling position, the bag separating position and the like.
The first driving assembly 51 may include a first bracket 511, a first guide rail pair 513 and a first driving module 515, the first bracket 511 may be mounted to the second driving assembly 53, and the first guide rail pair 513 and the first driving module 515 may be mounted to the first bracket 511. The first support 511 may be used as a base of the first driving assembly 51 and used for carrying the first guiding rail pair 513, the first driving module 515, and the like, and the first support 511 may also be used as a connecting member of the first driving assembly 51 so as to be connected and combined with other structures.
The first guide rail pair 513 may be a universal component to simplify the manufacturing difficulty and cost of the first guide rail pair 513. The support rail of the first rail pair 513 may be fixedly coupled to the first bracket 511 by a fastener such as a screw, a bolt, or the like. The first bag supporting member 10 and the second bag supporting member 30 may be respectively connected to two different sliding blocks 5131 of the first rail pair 513, for example, the first bag supporting member 10 may be fixedly connected to the sliding block 5131 of the first rail pair 513 by a fastener such as a screw, a bolt, etc., and the second bag supporting member 30 may be connected to the other sliding block 5131 of the first rail pair 513 by the same connection method.
The first driving module 515 may be respectively connected to the first bag supporting member 10 and the second bag supporting member 30, so that the first driving module 515 may drive the first bag supporting member 10 and the second bag supporting member 30 to slide on the first guide rail pair 513. The first driving module 515 may include a driving motor, a master synchronizing wheel, a slave synchronizing wheel, and a timing belt, and both the driving motor and the slave synchronizing wheel may be mounted to the first frame 511. The body of the driving motor may be fixedly coupled to the first bracket 511 by a fastening member such as a bolt or a screw, and the output shaft of the driving motor may be fixedly coupled to the main synchronizing wheel. The slave synchronizing wheel is rotatably mounted to the first bracket 511. The synchronous belt is sleeved on the main synchronous wheel and the auxiliary synchronous wheel, so that the driving motor can drive the synchronous belt to drive, and the belt driving effect is realized. The hold-in range can be connected with first bag spare 10, the second bag spare 30 of propping respectively, for example first bag spare 10 of propping can combine or other structure fixed connection in hold-in range through the lock, and the second props bag spare 30 and also can adopt same connected mode to be fixed in the hold-in range, so under driving motor drive, the hold-in range can drive simultaneously first bag spare 10 of propping and the second props bag spare 30 motion. The first driving module 515 drives the first bag supporting member 10 and the second bag supporting member 30 to approach or separate from each other in a synchronous belt manner, and the movement manner is simple and efficient.
