Detailed Description

The disclosed embodiments provide a follower device 30. As shown in fig. 1 and 2, the follower device 30 includes a first coupling end 32 and a second coupling end 34. The first coupling end 32 and the second coupling end 34 have a mating width in a first direction F and have a guiding length in a second direction S orthogonal to the first direction F. One of the first coupling end 32 and the second coupling end 34 is capable of driving the other to move in a first direction F and guiding the other to move in a second direction S. At least one of the first coupling end 32 and the second coupling end 34 is an adjustable end, the mating width of which is adjustable.

In the above technical scheme provided by the embodiment of the disclosure, by adjusting the fitting width of the adjustable end, the fitting precision between the first coupling end and the second coupling end can be adjusted by changing the fitting width, so that the first coupling end and the second coupling end do not need higher machining precision. In this way, the follower can have a low manufacturing cost. In addition, even if the first coupling end and the second coupling end are degraded in fitting accuracy due to abrasion or the like after long-time use, the fitting accuracy can be ensured by adjusting the fitting width, so that the following device can have lower maintenance cost.

In some examples, as shown in fig. 1 and 2, the first coupling end 32 is an adjustable end and the second coupling end 34 is a non-adjustable end. Here, the mating width of the non-adjustable end is not adjustable. In other examples, the first coupling end 32 and the second coupling end 34 may both be adjustable ends, or the first coupling end 32 may be a non-adjustable end.

In some examples, the first direction F is a horizontal direction and the second direction S is a vertical direction.

In some examples, as shown in fig. 1 and 2, the second coupling end 34 drives the first coupling end 32 to move in the first direction F and directs the first coupling end 32 to move in the second direction S. In other examples, the first coupling end 32 may drive the second coupling end 34 to move in the first direction F and direct the second coupling end 34 to move in the second direction S.

In some examples, as shown in fig. 2, the adjustable end includes a first adjustment element 36 and a second adjustment element 38. The first adjustment element 36 and the second adjustment element 38 are arranged opposite in the first direction F.

When the positioning element 40 is not screwed down, the positioning element 40 is unlocked from the rail, and the first adjustment element 36 and the positioning element 40 can move relative to the sliding seat 94 in the first direction F.

In some examples, as shown in fig. 2, at least a portion of second adjustment element 38 is fixedly coupled to slide mount 94.

The moving plate 152 is provided with a kidney-shaped hole through which the fastener 154 passes, the kidney-shaped hole extending in the first direction F. The moving plate 152 is secured to the mounting plate 146 when the fasteners 154 are tightened. When the fastener 154 is not tightened, the moving plate 152 can move in the first direction F under the guidance of the kidney-shaped hole.

In some examples, as shown in fig. 5, the follower 30 further includes a mount 156, a jackscrew 158, and an adjustment post 160. The mounting block 158 is fixedly connected to the mounting plate 146, and the jackscrews 158 are screwed with the mounting block 156. The axial direction of the jackscrew 158 is parallel to the first direction F. By screwing the jackscrew 158, the jackscrew 158 can be moved in the first direction F. The adjustment post 160 is fixedly connected to the moving plate 152, and an end of the jackscrew 158 can abut against the adjustment post 160, thereby restricting the movement of the adjustment post 160 to the side of the jackscrew 158. In this way, the jackscrew 158 is able to share the load of the idler pulley 122 in the first direction F, resulting in a higher reliability of the follower 30. In addition, the jackscrew 158 can also be used to closely adjust the distance between the drive pulley 120 and the idler pulley 122 so that the degree of tightness of the timing belt 124 is easily adjustable.

In some examples, as shown in fig. 5, the follower 30 further includes a web 162. The connection plate 162 is fixedly connected between the adjustment post 150 and the adjustment post 160, and is spaced apart from the moving plate 152 in the second direction S.

In some examples, as shown in fig. 5, follower 30 also includes a nut 164. The nut 164 is threaded with the top wire 158. When the nut 164 is tightened, the nut 164 abuts against the mount 156, and the jackscrew 158 is fixed relative to the mount 156. When the nut 164 is not tightened, the nut 164 is disengaged from the mount 156 and the jackscrew 158 is able to rotate relative to the mount 156 to move in the first direction F.

In some examples, as shown in fig. 1 and 3, the follower device 30 further includes a seal plate 166, a connection plate 168, and a moving plate 170. The mounting plate 146 and the closing plate 166 are fixedly and stacked on each other, with the connecting plate 132 disposed between the mounting plate 146 and the closing plate 166. The connection plate 132 is connected to the second coupling end 34 via a connection plate 168 and a moving plate 170, with the closing plate 166 separating the connection plate 132 from the moving plate 170.

In some examples, as shown in fig. 1, the moving plate 170 is fixedly connected to the guide post 52 via a base 172.

Embodiments of the present disclosure also provide a filling machine 58. As shown in fig. 1, the filling machine 58 includes a follower 30 and one or more filling heads 60, the filling heads 60 being mounted to the other of the first and second coupling ends 32, 34.

In some examples, as shown in fig. 1, a plurality of filling heads 60 are arranged side by side in a first direction F, with the filling direction of the filling heads 60 being parallel to a second direction S.

In some examples, as shown in fig. 1, the filling machine 58 further includes a bracket 176. The slide seat 94 is fixedly connected with the bracket 176, and the filling head 60 is detachably mounted on the bracket 176.

In some examples, as shown in fig. 1, a bracket 176 holds the filling head 60.

In some examples, as shown in fig. 1, the filling machine 58 further includes a mounting seat 178. The slide mount 94 is fixedly coupled to the bracket 176 via a mount 178.

In some examples, the filling head 60 is used to fill the packet with, for example, a liquid or powder. Specifically, the wrapper is movable in the first direction F relative to the platen. When the package reaches below the filling head 60, the filling head 60 can move in the second direction S so that the filling head 60 is close to the package. At the same time, the filling head 60 can be moved synchronously with the wrapping material in the first direction F. In the process of synchronously moving the filling head 60 and the packing material, the filling head 60 can fill liquid or powder into the packing material. After the filling is completed, the filling head 60 can move along the second direction S, so that the filling head 60 is far away from the package material.

In some examples, the packaging material is a penicillin bottle.
