Description

Technical Field

[0001] The utility model relates to the field of packaging machines, and particularly relates to a high-speed packaging machine and its clutch transmission mechanism. Background Art

[0002] In the prior art, a high-speed packaging machine such as a high-speed packaging machine and its charging device disclosed in CN219790577U with a publication number and a publication date of October 3, 2023, has a clutch assembly and a brake disc at the bottom end of its rotating shaft. When the clutch assembly is closed, the driving mechanism drives the rotating shaft to rotate through the clutch mechanism. When the clutch assembly is separated, the driving mechanism cannot drive the rotating shaft to rotate. The upper brake disc in this solution has a first state of separating from the lower brake disc after the clutch assembly is closed and a second state of contacting the lower brake disc after the clutch assembly is separated; when it is not necessary for the rotating shaft and the filling unit to rotate synchronously, the clutch assembly is closed to separate it, and the upper brake disc on the rotating shaft moves downward to contact and friction with the lower brake disc, completing deceleration and stopping rotation. This structure has the problem that when the upper clutch part and the lower clutch part are closed, they are prone to collide, resulting in damage, affecting the service life and working stability.

[0027] The embodiments of the present utility model will be further described below with reference to the accompanying drawings:

[0028] As shown in the figure, a clutch drive mechanism of a high-speed packaging machine includes a frame 1 and a rotating shaft 2, and further includes:

[0029] A clutch assembly, which is sleeved at the bottom end of the rotating shaft 2 and includes an upper clutch member 3 and a lower clutch member 4 having two states of closing and opening;

[0030] A driving assembly, which is installed on the frame 1 and is linked to the bottom end of the rotating shaft 2;

[0031] The output end of the driving assembly is fixedly connected to the lower clutch member 4. The rotating shaft 2 is in rotational fit with the upper clutch member 3. A transmission gear 5 that is in rotational fit and fixedly connected to the upper clutch member 3 is further provided on the rotating shaft 2. In this technical solution, a driving assembly is provided at the lower end of the rotating shaft, so as to drive the rotating shaft and the lower clutch member to rotate, so that the rotation speed of the lower clutch member is synchronized with the rotation speed of the upper clutch member. In this way, when the lower clutch member and the upper clutch member are closed, they will not collide. In addition, the driving assembly also has a braking effect, which prolongs the service life and improves the working stability.

[0032] A transmission assembly 11 that meshes with the transmission gear 5 is further provided on the frame 1. The structure of the transmission assembly has been disclosed in the prior art with the publication number of CN219790577U, and will not be elaborated here.

[0033] A convex block 31 is provided on the lower surface of the upper clutch member 3, and a groove 41 adapted to the convex block 31 is provided on the upper surface of the lower clutch member 4; alternatively, the groove can also be provided on the upper clutch member, and the convex block can be provided on the lower clutch member.

[0034] Embodiment 1: When the number of convex blocks 31 is greater than one, the sizes of the respective convex blocks 31 are different, and each groove 41 is respectively adapted to a different convex block 31; in this embodiment, there are five convex blocks, and their sizes are all different. Only after the convex block and the groove completely match will the upper clutch member and the lower clutch member be adsorbed, which can achieve the effect of accurate positioning. Moreover, the five convex blocks can greatly increase the contact area and prolong the service life of the electromagnetic clutch. Of course, one convex block and one groove can also be provided, but in this case, the acting force will be concentrated at one point, shortening the service life.

[0035] Embodiment 2: This embodiment is not illustrated. When the number of convex blocks 31 is greater than one, the sizes of the respective convex blocks 31 are the same, and each groove 41 is adapted to all the convex blocks 31. Each convex block can be adapted to all the grooves, and the effect achieved is the same as that of Embodiment 1.

[0036] The clutch assembly uses electromagnetic clutches, which are all prior arts and are obtained through procurement, having the advantage of low cost.

[0037] In addition, the clutch assembly can also adopt a pneumatic clutch structure. The clutch assembly further includes a cylinder 12 rotatably mounted on the rotating shaft 2 and located below the lower clutch member 4. Bearings 13 are respectively provided between the movable end of the cylinder 12 and the lower clutch member 4 and between the cylinder body of the cylinder 12 and the rotating shaft 2; A connecting frame 14 connecting the two is provided between the mounting frame 9 and the cylinder body of the cylinder 12. The connecting frame fixes the cylinder. The cylinder rotates relative to the rotating shaft, and the cylinder also rotates relative to the lower clutch member. Moreover, the movable end of the cylinder is sleeved on the lower clutch member and can drive the lower clutch member to move up and down.

[0038] The drive assembly includes:

[0039] A servo motor 6, which is fixedly installed on the frame 1;

[0040] A speed reducer 7, which is installed at the output end of the servo motor 6;

[0041] A coupling 8, which is linked and connected between the rotating shaft 2 and the output end of the speed reducer 7;

[0042] The coupling 8 is fixedly connected to the lower clutch member 4. The servo motor drives the output end of the speed reducer to rotate, and then drives the rotating shaft and the lower clutch member to rotate through the coupling. After the rotational speed is the same as that of the upper clutch member, the closing of the upper clutch member and the lower clutch member will not cause tooth collision.

[0043] An installation frame 9 for installing the servo motor 6 and the speed reducer 7 is provided on the frame 1. An energized switch 10 in contact with the clutch assembly is provided on the installation frame 9, which can be used to detect the working condition of the clutch assembly.

[0044] A high-speed packaging machine includes a film feeding device, a packaging bag forming device, a longitudinal sealing device, a sealing device, and a filling device; The filling device includes the clutch transmission mechanism as described above. The film feeding device, the packaging bag forming device, the longitudinal sealing device, the sealing device, and the filling device of the high-speed packaging machine in this technical solution are the same as those of the prior art with the publication number CN219790577U. The difference lies in the clutch transmission mechanism, and it also has all the advantages of the above clutch transmission mechanism.
