Description

Technical Field

[0001] The utility model relates to the technical field of packaging machines, in particular to a bag dividing device of a three-side-sealed vertical counting packaging machine. Background Art

[0002] The three-side-sealed vertical packaging machine is an automatic packaging equipment, that is, after the packaging bag is sealed by the longitudinal sealing mechanism and the transverse sealing mechanism, the material is automatically filled into the packaging bag by the filling mechanism, and then the other side of the packaging bag is sealed by the transverse sealing mechanism, and then the packaging bag is cut by the bag dividing device.

[0003] For example, a Chinese patent technical document with announcement number CN217598910U discloses a double-sheet film four-side sealed vertical packaging machine, comprising a main box body, wherein an auxiliary film roll holder and a main film roll holder are respectively installed at the left and right ends of the top of the main box body, a double-sheet film former is arranged at the center of the top of the main box body, a longitudinal sealing mechanism is arranged at the bottom of the double-sheet film former, a transverse sealing draw tape mechanism is arranged at the bottom of the longitudinal sealing mechanism, and a cutting mechanism is arranged at the bottom of the transverse sealing draw tape mechanism. After the packaging material passes through the main roll mold holder and the auxiliary roll mold holder and enters the double-sheet film former, it is initially formed and then sealed by the longitudinal sealing machine.

[0004] It can be seen from the above disclosed content that in the above technical scheme, the sealing principle of four-side sealing is the same as the sealing principle of three-side sealing, that is, after the packaging bag is sealed by the longitudinal sealing mechanism and the transverse sealing mechanism, the packaging bag is separated by the corresponding bag separating mechanism. In the above technical scheme, the bag separating mechanism drives the tool holder used to connect the tool head to move toward each other through two independently arranged cylinders to complete the separation of the packaging bag. Therefore, in order to ensure that the incision is flush, the cylinders on both sides need to be controlled synchronously, which increases the programming difficulty and is not convenient for the overall installation and debugging. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a bag dividing device for a three-side-sealed vertical counting packaging machine, which can make the overall installation and debugging more convenient.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bag dividing device of a three-side sealing vertical counting packaging machine, comprising a mounting frame, wherein guide rods are symmetrically arranged in the mounting frame, and a first connecting seat and a second connecting seat that can slide are mounted on the outer periphery of the guide rods, and a bag dividing area is formed between the first connecting seat and the second connecting seat, and an abutment seat and a knife seat for connecting a knife head are provided in the bag dividing area, and the first connecting seat is connected to a driving cylinder, and the driving cylinder is fixed to the inner wall of the mounting frame, and a transmission mechanism is provided on the side of the guide rod facing the mounting frame, and the driving cylinder drives the first connecting seat and the second connecting seat to move toward or away from each other through the transmission mechanism, and an adjustment mechanism is provided on the outer side of the mounting frame, and the adjustment mechanism is connected to the packaging machine body, and the adjustment mechanism is used to adjust the horizontal position of the bag dividing area.

[0007] The utility model is further configured as follows: the transmission mechanism includes a rotating shaft, the rotating shaft is rotatably connected to the inner wall of the mounting frame, a mounting sleeve is fixedly mounted on the outer periphery of the rotating shaft, a protruding first connecting flange and a second connecting flange are provided on the outer periphery of the mounting sleeve, the first connecting flange and the second connecting flange are symmetrical to each other, a first connecting rod is provided between the first connecting seat and the mounting sleeve, one end of the first connecting rod is rotatably connected to the first connecting seat, and the other end is rotatably connected to the first connecting flange, a second connecting rod is provided between the second connecting seat and the mounting sleeve, one end of the second connecting rod is rotatably connected to the second connecting seat, and the other end is rotatably connected to the second connecting flange, the first connecting rod and the second connecting rod are centrally symmetrical to each other.

[0008] The utility model is further configured as follows: the second connecting seat includes a connecting portion and a supporting portion, the connecting portion is used to connect to the knife seat, a pressure spring is provided between the supporting portion and the second connecting seat, one end of the pressure spring is fixed to the supporting portion, and the other end is fixed to the connecting portion.

[0009] The utility model is further configured as follows: the knife seat is provided with a first connecting hole that penetrates through, and the knife head is provided with a second connecting hole that can be opposite to the first connecting hole.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] Since a transmission mechanism is provided, when the packaging bags are divided, the first connecting seat and the second connecting seat can be moved simultaneously along the direction of the guide rod only by controlling the extension and retraction of the output end of the driving cylinder, so that the abutment seat and the knife seat respectively connected to the first connecting seat and the second connecting seat can move toward or away from each other synchronously, thereby completing the division of the packaging bags. Therefore, under the action of the transmission mechanism, only a single driving cylinder is required to synchronously drive the first connecting seat and the second connecting seat to move, thereby reducing the programming difficulty and facilitating the overall installation and debugging. In addition, the setting of the abutment seat can support the knife head when the first connecting seat and the second connecting seat move toward each other, thereby ensuring that the incision of the packaging bag is flush.

[0017] like Figure 1 to Figure 2As shown, the utility model discloses a bag dividing device of a three-side sealing vertical counting packaging machine, including a mounting frame 1, wherein guide rods 2 are symmetrically arranged in the mounting frame 1, and a first connecting seat 3 and a second connecting seat 4 which can slide are sleeved on the outer periphery of the guide rod 2, and a bag dividing area 100 is formed between the first connecting seat 3 and the second connecting seat 4, and an abutting seat 5 and a knife seat 6 for connecting a knife head 7 are arranged in the bag dividing area 100, and the first connecting seat 3 is connected to a driving cylinder 8, and the driving cylinder 8 is fixed to the inner wall of the mounting frame 1, and a transmission mechanism is arranged on the side of the guide rod 2 facing the mounting frame 1, and the driving cylinder 8 drives the first connecting seat 3 and the second connecting seat 4 to move toward or away from each other through the transmission mechanism, and an adjusting mechanism is arranged on the outer side of the mounting frame 1, and the adjusting mechanism is connected to the packaging machine body 200, and the adjusting mechanism is used to adjust the horizontal position of the bag dividing area 100, and when the packaging bags are divided, it is only necessary to control the driving cylinder 8 The extension and retraction of the output end can make the first connecting seat 3 and the second connecting seat 4 move along the direction of the guide rod 2 at the same time, so that the abutment seat 5 and the knife seat 6 respectively connected to the first connecting seat 3 and the second connecting seat 4 can synchronously move toward or away from each other, thereby completing the bag separation of the packaging bags. Therefore, under the action of the transmission mechanism, only a single driving cylinder 8 is required to synchronously drive the first connecting seat 3 and the second connecting seat 4 to move, thereby reducing the programming difficulty and facilitating the overall installation and debugging. The setting of the abutment seat 5 can support the knife head 7 when the first connecting seat 3 and the second connecting seat 4 move toward each other, thereby ensuring that the incision of the packaging bag is flush. In addition, through the setting of the adjustment mechanism, the horizontal position of the bag separation area 100 can be adjusted, thereby ensuring that the packaging bag passes through the bag separation area 100 in a vertical posture, thereby further ensuring that the incision of the packaging bag is flush.

[0018] In this embodiment, the specific structure of the transmission mechanism includes a rotating shaft 91, which is rotatably connected to the inner wall of the mounting frame 1, and a mounting sleeve 92 is fixedly mounted on the outer periphery of the rotating shaft 91. The outer periphery of the mounting sleeve 92 is provided with a protruding first connecting flange 921 and a second connecting flange 922, and the first connecting flange 921 and the second connecting flange 922 are symmetrical to each other. A first connecting rod 923 is provided between the first connecting seat 3 and the mounting sleeve 92, and one end of the first connecting rod 923 is rotatably connected to the first connecting seat 3, and the other end is rotatably connected to the first connecting flange 921.

[0021] In this embodiment, the specific structure of the adjustment mechanism includes a base 11 fixed to the packaging machine body 200, a screw 12 is rotatably connected between the two side bases 11, a limit rod 13 is provided on the outside of the screw 12, and a first guide seat 14 and a second guide seat 15 are fixed on the outside of the mounting frame 1. The first guide seat 14 is mounted on the outer periphery of the screw 12 and forms a threaded fit with the screw 12. The second guide seat 15 is mounted on the limit rod 13 and can form a sliding fit with the limit rod 13. Therefore, by rotating the screw 12, the mounting frame 1 can move along the direction of the screw 12 under the limiting action of the limit rod 13 through the first guide seat 14 that is mounted on the outer periphery of the screw 12 and forms a threaded fit with the screw 12. In this way, the horizontal position of the bagging area 100 can be adjusted.
