Description

Technical Field

[0001] The utility model relates to the technical field of packaging machines, in particular to a film head clamping mechanism. Background Art

[0002] When the existing packaging machine is packaging, the installation position of the film roll is relatively not very important. What is important is that the film head on the spare film roll can be installed on the pulling path of the film roll on the original packaging machine, so that the film head of the spare film roll is connected to the tail of the previous film roll, thereby realizing uninterrupted packaging using the film roll. The action of pulling the film head of the existing packaging machine to the packaging path of the original film roll of the packaging machine is basically manual pulling and traction, because when replacing the spare film roll, the film head of the film roll needs to be unfolded before the film head can be grabbed for traction.

[0003] In order to realize full automation of packaging machines, reduce manual intervention and reduce labor costs, we set up a placement station on or near the packaging machine equipment to place spare film rolls, and in order to solve the problem that the film head needs to be manually pulled, we provide a film head clamping mechanism.

[0013] As a further improvement, the fixed film clamping assembly also includes a support frame, and the support frame is installed on the top of the film clamping member.

[0014] As a further improvement, the film clamping assembly includes a clamping component for connecting to the film head, and the width of the clamping component is adapted to the film clamping station;

[0020] 2. After the original film roll on the packaging machine is used up, the utility model starts the driving motor in the film clamping assembly to make the rotating shaft carry the clamping component to move to the film clamping station, and then the movable plate and the fixed plate clamp the film head of the film roll through the second driving unit in the clamping component, and then the clamping component carries the film head and moves to the movement path of the original film roll of the packaging machine, that is, the device can make the film head of the spare film roll automatically located at the tail of the original film roll, without the need to manually pull the film head of the spare film roll.

[0031] See also Figure 1-Figure 5 The membrane head clamping mechanism of the utility model comprises:

[0032] A fixed film clamping assembly 2 installed near the spare film roll 1, the fixed film clamping assembly 2 is used to clamp the film head of the spare film roll 1;

[0033] A traction film clamping assembly 3, which is used to pull the membrane head to move to the installation position of the membrane head;

[0034] The fixed film clamping assembly 2 comprises a film clamping frame, on which a film clamping station 4 and a locking component for fixing the film head in the film clamping station 4 are provided;

[0035] The film clamping frame includes two film clamping plates 21, and the two film clamping plates 21 are respectively provided with film clamping grooves 22 for the film head to enter, and the two film clamping grooves 22 and the path therebetween form a film clamping station 4;

[0036] The locking component includes a first driving unit 24 , on which a film clamping member 23 capable of clamping the film clamping groove 22 is mounted.

[0037] When in use, since the fixed film clamping assembly 2 of the device is installed near the spare film roll 1, the film head of the spare film roll 1 can be unfolded when the spare film roll 1 is placed manually, and then the film head of the film roll is placed into the film clamping station 4, and the first driving unit 24 in the locking component carries the film clamping member 23 to move to the clamping film head, thereby preventing the film head of the film roll from being messy after unfolding. After the film roll on the packaging machine is used, the clamped film head does not need to be manually unfolded.

[0038] When the original film roll on the packaging machine is used up, the driving motor 33 in the film clamping assembly 3 is started to make the rotating shaft 32 carry the clamping component 31 to move to the film clamping station 4, and then the second driving unit 313 in the clamping component 31 is used to clamp the film head of the film roll, and then the clamping component 31 is moved with the film head to the movement path of the original film roll of the packaging machine, that is, the device can make the film head of the spare film roll 1 automatically located at the tail of the original film roll, without the need to manually pull the film head of the spare film roll 1.

[0039] As a further improvement, the specific embodiment 1 is applied to the original online axial film-drawing packaging machine of our company. Because the film roll used is a thin film, in order to avoid the film head being broken and hung on the equipment after being clamped; specifically, the film clamping station 4 is arranged perpendicular to the film roll, which can facilitate the film head of the spare film roll 1 to be gathered and clamped, so that it is convenient for the film head to enter the film clamping station 4 for clamping, and at the same time, the strength of the film head can be increased to avoid the film head being broken and hung on the equipment during clamping.

[0040] Furthermore, the film clamping member 23 rotates with the opening direction of the film clamping groove 22 as the closest rotation path, so that the film clamping member 23 moves from the opening direction of the film clamping groove 22 to the closing direction, thereby effectively ensuring the clamping of the film head located in the film clamping groove 22, and ensuring that the film head will not fall off after contacting the film clamping member 23.

[0041] The fixed film clamping assembly 2 also includes a support frame 25, which is installed on the top of the film clamping member 23. By allowing the unfolded film head to bypass the support frame 25 and then enter the film clamping station 4, it is convenient to gather the film heads and can effectively change the film length between the spare film roll 1 and the film clamping station 4, thereby adapting to the moving range of the traction film clamping assembly 3 to carry the film head.

[0042] The specific locking components include two film clamping plates 21 and two first driving units 24. The two film clamping parts 23 are installed on the outside of the two film clamping parts 23, and the end of the film clamping part 23 away from the opening of the film clamping groove 22 is rotatably connected to the film clamping plate 21. The two first driving units 24 are respectively used to drive the two film clamping parts 23 to rotate. The first driving unit 24 is a pneumatic spring, which rotates the film clamping part 23 to clamp the two ends of the film clamping station 4.

[0043] The film clamping assembly includes a clamping component 31 for connecting with the film head, and the width of the clamping component 31 is adapted to the film clamping station 4;

[0044] The clamping component 31 includes a fixed plate 311, a movable plate 312 is disposed above the fixed plate 311, and the clamping component 31 also includes a second driving unit 313 for driving the movable plate 312 to move toward the fixed plate 311 to form a clamp;

[0045] The traction clamping film assembly 3 further includes a rotating shaft 32 and a driving motor 33 for driving the rotating shaft 32 to rotate.

[0046] When in use, the driving motor 33 drives the clamping component 31 to rotate through the rotating shaft 32, so as to effectively clamp the film head located at the film clamping station 4 and pull it to the film roll path of the packaging machine;

[0047] In the online axial film-stretching packaging machine of this equipment, not only the film head needs to be transferred, but the spare film roll 1 also needs to be replaced in the online axial film-stretching packaging machine to replace the original film roll. The replacement method can be achieved by robot grabbing and replacing, and the specific method will not be further described in this case.

[0048] The above is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
