Description

A rotary arm type lifting film baler

technical field

The utility model relates to a rotary arm type lifting film packing machine.

Background technique

The packing machine is a kind of mechanical equipment in the field of packaging machinery. It is used to automatically wrap the film on the predetermined object to wrap the predetermined object to prevent dust and fix it. In order to meet the packaging requirements of containerized storage, transportation and mechanized loading and unloading of goods, it is divided into tray-type balers, top-pressing drag-type balers, pre-stretch automatic film wrapping and wrapping machines, and rotary arm film balers.

In the prior art, the rotary arm type film packer is generally used to pack the goods conveyed by the conveyor belt on the production line. For the film wrapping of objects with a certain height and which can be placed stably, it generally uses a circular motion. However, this kind of baler cannot be lifted up and down when winding the film, and can only use a wider film to pack larger items. If the items on the conveyor belt are different, there are both larger items and smaller items. , it is difficult to complete the packaging of all items.

Moreover, in the process of packing loose items, the packaging will be inconsistent and irregular due to the loose film winding of the items, and the packaging is not strong and reliable, and it is prone to deviation, which affects the packaging effect.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail:

As shown in Fig. 1, a kind of cantilever type lift film packing machine of the present utility model, comprises frame body 1, and frame body 1 is erected on the conveyer belt of assembly line, and the top of frame body 1 is provided with rotating motor 2, and rotating motor 2 passes through worm wheel The worm mechanism is driven and connected with a rotating gear 3 that can rotate horizontally, and the center of the rotating gear 3 is vertically pierced with a lifting rod 5 that can rotate axially. In order to make the rotating gear 3 and the elevating rod 5 rotate without interfering with each other, the center of the rotating gear 3 is provided with a bearing, the rotating gear 3 is connected with the outer ring of the bearing, and the elevating rod 5 passes through the inner ring of the bearing and is connected with the inner ring of the bearing.

The lower surface of the lifting rod 5 is provided with threads and is connected with a lifting plate 6 by threads. The lifting plate 6 and the lifting rod 5 form a nut screw mechanism. The bottom end of the lifting rod 5 passes through the lifting plate 6 and is provided with a lifting gear 8. 5. The bottom is provided with a lifting motor 7, and the lifting motor 7 is driven and connected with the lifting gear 8 through a worm gear mechanism. The bottom of the rotating gear 3 is vertically fixedly connected with guide rods 4 positioned at both sides of the lifting rod 5 , and the lower ends of the guide rods 4 run through the lifting plate 6 . The lifting motor 7 drives the lifting gear 8 to rotate, and then drives the lifting rod 5 to rotate axially, so that the lifting plate 6 moves up and down along the lifting rod 5 .

One end of the lifting plate 6 is connected with a vertical cantilever 9, and the bottom of the cantilever 9 is connected with a horizontal supporting plate 10. The supporting plate 10 is provided with a film winding shaft 11, and the film winding shaft 11 is provided with a film tension adjustment mechanism. The film tension adjustment mechanism includes a blocking cap 14 fixed on the top of the film winding shaft 11. Below the blocking cap 14 is provided a lower pressing plate 12 which is worn on the film winding shaft 11 and can slide up and down. Between the lower pressing plate 12 and the blocking cap 14 There is a spring 13 sheathed on the film winding shaft 11, and the bottom of the film winding shaft 11 passes through the supporting plate 10 and is screwed with a nut 15. By turning the nut 15, adjust the length of the film winding shaft 11 above the supporting plate 10, the film wound on the film winding shaft 11 is squeezed by the lower platen 12 and the supporting plate 10, and the film winding shaft 11 is above the supporting plate 10 The longer the length, the smaller the extrusion force, the smaller the tension of the film when winding, and vice versa. It can be adjusted flexibly according to the actual items. The spring 13 between the blocking cap 14 and the lower pressing plate 12 can play a buffering role to avoid the rigid extrusion of the lower pressing plate 12 .

Its working principle is: when the items on the conveyor belt are conveyed to the bottom of the frame body 1, the packaging starts. At the beginning, the film winding shaft 11 is located at the bottom of the items, and the film is pulled out from the film winding shaft 11 and pasted on the items, and the Rotating motor 2, rotating motor 2 drives rotating gear 3 to rotate, rotating gear 3 drives cantilever 9 to rotate around the object, and simultaneously turns on lifting motor 7, lifting motor 7 drives lifting rod 5 to rotate axially, so that supporting plate 10 and cantilever 9 move along the lifting rod 5 rise, that is, when the cantilever 9 rotates around the article, the cantilever 9 gradually rises, and in this process, the wrapping of the film to the article is completed.

The above description is only the preferred implementation mode of this patent. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of this patent, some improvements and replacements can also be made. These improvements and replacements It should also be regarded as the scope of protection of this patent.
