The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.

The embodiment provides a bottle driving mechanism of a film packaging machine, which is positioned at the downstream of a bottle separating mechanism so as to receive materials from the bottle separating mechanism. The bottle driving mechanism can be used for conveying orderly arranged bottle bodies to the subsequent film-covered packaging step after the orderly arranged bottle bodies are arranged in a staggered mode. As shown in fig. 1,2 and 4, the bottle driving mechanism 400 includes a guide rail 1, a first bottle driving assembly 2, a second bottle driving assembly 3, a mesh belt assembly (not shown), a driving assembly 5 and a transmission assembly 6.

It will be appreciated that the bottle separating mechanism 300 of the film wrapping machine is capable of displaying the material 10 in a rectangular array. In this embodiment, referring to fig. 4, the materials 10 are divided into a plurality of groups, and each group of materials 10 includes a plurality of bottles sequentially arranged along a first direction, the first direction being parallel to a conveying direction of the materials 10.

Specifically, the guide rails 1 extend along the first direction and are respectively disposed at two sides of the rack 100, and along the extending direction of the guide rails 1, the distance between two opposite sides of the guide rails 1 gradually decreases, that is, the accessible distance between the guide rails 1 gradually narrows. The first bottle driving assembly 2 comprises a first bottle driving rod 21 and a plurality of dislocation clamping blocks 22, the first bottle driving rod 21 is arranged on the frame 100 and can move along a first direction, the dislocation clamping blocks 22 are arranged on the first bottle driving rod 21 at intervals and can slide, and each dislocation clamping block 22 corresponds to a group of materials 10.

That is, the first bottle driving rod 21 can push the materials 10 from the bottle separating mechanism 300 between the two guide rails 1, and meanwhile, the dislocation fixture block 22 can push the corresponding group of materials 10 to move, so that the group of materials 10 corresponding to the dislocation fixture block 22 is displaced forward along the first direction compared with the adjacent groups of materials 10, and any adjacent groups of materials 10 in the groups of materials 10 are dislocated along the first direction. When the first bottle driving rod 21 continuously pushes the material 10 to move, the distance between the guide rails 1 on two sides is reduced, so that the two sides of the material 10 can receive the extrusion force from the guide rails 1. Under the action of the extrusion force of the guide rail 1, the dislocation fixture blocks 22 can slide along the length direction of the first bottle driving rod 21, so that each group of materials 10 are gradually close to each other, the distance between bottle bodies is more compact, and therefore film wrapping materials in a large package format are saved during subsequent film wrapping and the overall stability of the materials 10 during subsequent film wrapping is ensured.

Alternatively, referring to fig. 5 to 9, a plurality of sliding grooves 211 are formed on the first bottle driving rod 21 at intervals along the length direction, and the sliding grooves 211 are in one-to-one correspondence with the plurality of dislocation fixture blocks 22. The dislocating fixture 22 can slide along the sliding groove 211, and the length of the sliding groove 211 positioned at the end part is longer than that of the sliding groove 211 positioned at the middle part. It can be understood that the sliding distance of the dislocation fixture block 22 at the end is longer than that of the middle dislocation fixture block 22, and the sliding distance of the dislocation fixture block 22 at the end can be ensured by designing the length of the sliding groove 211 at the end longer.

Specifically, in the present embodiment, the sliding groove 211 on the first bottle driving rod 21 is a through-type waist-shaped groove, and the length direction thereof is parallel to the length direction of the first bottle driving rod 21. The dislocation fixture block 22 is provided with a connecting hole, and the connecting pin 221 sequentially penetrates through the connecting hole and the waist-shaped groove. When the connecting pin 221 slides along the waist-shaped groove, the dislocation fixture block 22 can be driven to slide.

Referring to fig. 6 and 8, the first bottle driving assembly 2 further includes a plurality of reset elastic members 23, and the reset elastic members 23 are in one-to-one correspondence with the dislocation fixture blocks 22. An installation cavity 212 is arranged in the first bottle driving rod 21, and the installation cavity 212 is communicated with the sliding groove 211. The reset elastic member 23 is disposed in the mounting cavity 212, and two ends of the reset elastic member 23 are respectively connected to the connecting pin 221 and the inner wall of the mounting cavity 212. The dislocation fixture block 22 presses or stretches the reset elastic member 23 to elastically deform when sliding along the length direction of the sliding slot 211. When the dislocating clamping block 22 is not subjected to external force, the reset elastic piece 23 is restored to the original state, and the dislocating clamping block 22 is driven to reset. The return elastic member 23 may be, but not limited to, a return spring, and any other elastic member capable of stretching or compressing and recovering the deformation may be used, and is not limited herein.

In this embodiment, the first bottle driving rod 21 has a rectangular tubular structure, and a hollow inner cavity thereof is the mounting cavity 212. The first bottle driving rod 21 is designed into a hollow tube structure, so that the overall weight of the first bottle driving assembly 2 is reduced, and the aim of light weight design is fulfilled; at the same time, the first bottle driving rod 21 is convenient to drive, and the consumption of driving force is reduced.

More specifically, as shown in fig. 6, 8 and 9, the first bottle driving assembly 2 further includes a plurality of limiting members 24, and the plurality of limiting members 24 are in one-to-one correspondence with the plurality of reset elastic members 23. The limiting piece 24 is adjustably connected to the first bottle driving rod 21 along the length direction, is arranged at intervals with the sliding groove 211, the limiting piece 24 stretches into the mounting cavity 212, and two ends of the reset elastic piece 23 are respectively connected to the connecting pin 221 and the limiting piece 24. In this embodiment, the first bottle driving rod 21 is further provided with a plurality of limiting holes 214 spaced apart along the length direction, and the limiting member 24 can pass through the limiting holes 214 and extend into the mounting cavity 212, and two ends of the reset elastic member 23 are detachably connected to the connecting pin 221 and the limiting member 24 respectively. By passing the limiting member 24 through different limiting holes 214, the distance between the limiting member 24 and the dislocating clamping block 22 can be changed, and then the stress of the reset elastic member 23 can be changed. Illustratively, the stop 24 may be selected as a bolt.

In order to facilitate the installation of the reset elastic piece 23 in the first bottle driving rod 21, optionally, an installation opening 213 is further formed on the first bottle driving rod 21 along the length direction. The mounting port 213 communicates with the mounting chamber 212, and the return elastic member 23 can be placed and mounted in the mounting chamber 212 from the mounting port 213. It will be appreciated that the length of the mounting opening 213 is not less than the length of the return elastic member 23, so that the return elastic member 23 is placed in the mounting cavity 212, and both ends of the return elastic member 23 are connected to the connecting pin 221 and the stopper 24, respectively.

As shown in fig. 1, 2,4 to 6 and 10, guides 25 are provided on the two dislocated cartridges 22 at the ends, respectively. The guide piece 25 can slide along the adjacent guide rail 1 so as to drive the dislocation clamping blocks 22 at the two ends to move oppositely when the first bottle driving rod 21 moves along the first direction. That is, the guide 25 can bring the dislocation blocks 22 at both ends close to each other while narrowing the guide rails 1 at both sides. After the dislocation fixture block 22 contacts with the bottle bodies in the materials 10, the whole group of materials 10 can be pushed to move forward, and the bottle bodies at the two ends can contact with the guide rails 1 at the left side and the right side. During the movement of the first bottle driving rod 21 along the first direction, the materials 10 on two sides are drawn toward the middle and gradually narrowed. The two groups of materials 10 at the end part firstly move towards the middle, and then the materials 10 at the middle part are pushed to be close to the middle, so that the effects of stable dislocation and compact arrangement are achieved.

Specifically, the first guide portions 11 are provided on the guide rails 1, and the distance between the first guide portions 11 on the two guide rails 1 gradually decreases in the first direction. The guide 25 includes a second guide portion 251, and the second guide portion 251 is slidably connected to the first guide portion 11. By the engagement of the first guide portion 11 and the second guide portion 251, the dislocation fixture blocks 22 at both ends of the first bottle driving rod 21 can be moved in the first direction and also moved in the direction approaching each other. Illustratively, one of the first guide 11 and the second guide 251 includes a slide rail, and the other includes a roller in rolling engagement with the slide rail.

In this embodiment, two sliding rails are respectively disposed at the bottoms of the two guide rails 1 along the shape, and the two sliding rails extend along the first direction and gradually approach along the first direction. The guide member 25 further includes a connecting portion 252, the connecting portion 252 is fixedly connected to the dislocating fixture block 22, and the roller is rotatably disposed on the connecting portion 252. When the first bottle driving rod 21 pushes the material 10 to enter between the two guide rails 1 along the first direction, two rollers on the dislocation clamping blocks 22 at the two ends of the first bottle driving rod 21 respectively enter the two corresponding slide rails. When the first bottle driving rod 21 continues to move along the first direction, the rollers roll in the sliding rails, and along with the gradual decrease of the distance between the two sliding rails, the distance between the two rollers also gradually decreases, so as to drive the dislocation clamping blocks 22 at the two ends of the first bottle driving rod 21 to move towards each other.

Optionally, with continued reference to fig. 1,2 and 4, the second bottle driving component 3 is disposed between the bottle separating mechanism 300 and the first bottle driving component 2, the first bottle driving component 2 and the second bottle driving component 3 are both disposed on the mesh belt component, the mesh belt component is disposed on the frame 100, and a feeding end of the mesh belt component is connected to a discharging end of the bottle separating mechanism 300 so as to convey the material 10. The second bottle driving assembly 3 and the net belt assembly can carry out preliminary shaping on the material 10 from the bottle separating mechanism 300 and adjust the conveying speed of the material, so that the compactness and the speed synchronism of the material 10 pushed into the space between the two guide rails 1 by the first bottle driving assembly 2 are ensured.

Specifically, the second bottle driving assembly 3 includes a second bottle driving rod 31 and a guard rail 32. The two guardrails 32 are arranged, and the two guardrails 32 are parallel to the first direction and are respectively arranged at two sides of the frame 100. The distance between the two guardrails 32 is equal to the maximum distance between the two guide rails 1. The second bottle driving rod 31 can move along the first direction so as to push the material 10 at the feeding end of the net belt assembly into the space between the two guardrails 32, and the guardrails 32 can narrow the material 10 so as to eliminate the gap brought by the partition plate of the bottle separating mechanism 300.

In this embodiment, the second bottle driving rod 31 is a common polish rod. That is, no other parts are mounted on the second bottle driving rod 31, and when the second bottle driving rod 31 pushes the materials 10, the stress of each material 10 is uniform. Under the combined action of the second bottle driving rod 31 and the two guardrails 32, the material 10 cannot be misplaced or offset in the process of moving along the first direction.

As shown in fig. 1-4, the driving assembly 5 and the transmission assembly 6 are both disposed on the frame 100, and the driving assembly 5 is connected to the first bottle driving rod 21 and the second bottle driving rod 31 through the transmission assembly 6, and drives the first bottle driving rod 21 and the second bottle driving rod 31 to move along the first direction at the same speed. The first bottle driving rod 21 and the second bottle driving rod 31 have the same speed, so that stable switching of the material 10 between the first bottle driving assembly 2 and the second bottle driving assembly 3 can be ensured, and the conveying stability of the material 10 is ensured.

Specifically, the drive assembly 5 includes a driving member 51, a driving shaft 52, and a plurality of driven shafts. The fixed end of the driving member 51 is disposed on the frame 100, and the output end of the driving member 51 is connected to the driving shaft 52 to drive the driving shaft 52 to rotate. In this embodiment, the driving member 51 is preferably a motor, and the motor is mounted on one side of the frame 100, and an output shaft of the motor is connected to one end of the driving shaft 52 through a gear transmission or the like. The driving shaft 52 is in transmission connection with a plurality of driven shafts through the transmission assembly 6, and the plurality of driven shafts comprise a first driven shaft 53, a second driven shaft 54 and a third driven shaft 55. The driving shaft 52 rotates to drive the first driven shaft 53, the second driven shaft 54 and the third driven shaft 55 to synchronously rotate. Wherein, the driving shaft 52 and the first driven shaft 53 are matched with the first bottle driving assembly 2 to drive the first bottle driving rod 21 to move; the second driven shaft 54 and the third driven shaft 55 are matched with the second bottle driving assembly 3 so as to drive the second bottle driving rod 31 to move.

More specifically, the transmission assembly 6 includes a first transmission structure, a second transmission structure, and a third transmission structure. In the present embodiment, both ends of the driving shaft 52 are rotatably connected to both sides of the frame 100, respectively, and the first driven shaft 53 is parallel to the driving shaft 52 and connected to the frame 100 at the same height as the driving shaft 52. The first transmission structure comprises a first transmission wheel set 61 and a first transmission chain 62, the first transmission wheel set 61 comprises a plurality of first transmission gears, the first transmission gears are respectively connected at two ends of the driving shaft 52 and the driven shaft in a rotating mode, meanwhile, the first transmission gears are respectively connected at positions, opposite to the inlet and the outlet of the two guide rails 1, on the frame 100 in a rotating mode, the first transmission chain 62 is wound outside the plurality of first transmission gears on the same side of the frame 100, and two ends of the first bottle driving rod 21 are respectively connected to two links, opposite to the first transmission chain 62.

When the driving member 51 drives the driving shaft 52 to rotate, the driving shaft 52 drives the first driven shaft 53 to rotate through the first driving wheel set 61 and the first driving chain 62, and the first bottle driving rod 21 can circularly move along the shape track of the first driving chain 62 due to the fact that the first bottle driving rod 21 is connected between the first driving chains 62 on two sides, so that multiple groups of materials 10 are sequentially propped and pushed between the two guide rails 1. The bottle driving operation of the material 10 bottle group with various specifications can be applicable by changing the distance between two adjacent first bottle driving rods 21 on the first transmission chain 62.

Preferably, the first transmission structure may further comprise a plurality of tensioning wheels rotatably connected to the frame 100. The first transmission chain 62 can be tensioned through a plurality of tensioning wheels, so that the stability of the first bottle driving rod 21 in circular movement along the shape track of the first transmission chain 62 is ensured.
