Description

The object turning mechanism of the cold shrink film hood machine

The invention relates to a cold-shrinkable film hooding machine, more specifically, an object turning mechanism and an object-coating method of a cold-shrinkable film hooding machine.

About the previous technology of the cold-shrink film hood machine, such as the CN105905370A patent case cold-drawn hood machine, the frame and the hanging film assembly carried on the frame, the film feeding assembly, the heat-sealing film cutting assembly, the film opening assembly, the cover Membrane components. The film hanging assembly is arranged on the side of the frame to carry and fix the film roll. The film feeding component is set on the top of the frame, and transports the film to the film opening component. The heat-sealing film cutting assembly and the film opening assembly are arranged below the film feeding assembly. The film assembly is located at the bottom of the frame, including the film motor and the lifting chain. The film motor drives the lifting chain to move up and down. The lifting chain is set at the four corners of the frame to connect with the film assembly. Mantle action.

The object to be coated is carried by the pallet, and is loaded and moved into the above-mentioned coating machine through the conveying device. The film assembly is activated, and the cold shrinkable film is covered on the outside of the object from top to bottom. The shrink film tightly wraps the top surface of the object and its surrounding surfaces (usually the four sides), but the bottom surface of the object cannot be covered with the shrink film because it is blocked by the pallet. However, problems such as moisture or dirt tend to occur from the bottom of the item and are more likely to spread upwards.

In order to solve the above problems, this creation proposes an object turning mechanism for a cold shrink film hood machine And the object coating method, the object is fully covered (top surface, bottom surface and all surrounding surfaces) with cold shrinkable film.

The technical characteristics and functions of this creation:

An object overturning mechanism and object coating method of a cold shrinkable film hooding machine. After the cold shrinkable film hooding machine coats an object for the first time, the object overturning mechanism clamps and turns the object 180 degrees, and the cold shrinkable film The coating machine performs the second coating on the object, and the entire surface (top surface, bottom surface and all surrounding surfaces) of the object is covered by cold shrink film.

The terms "first", "second", and "third" used in the following description are only used to describe elements, and should not be understood as indicating or implying relative importance or order.

As shown in FIG. 1 to FIG. 3 , the creative object turning mechanism 20 is used in conjunction with the shrink film casing machine 10 . Shrinkable film hood machine 10 is a known technology, and is not a technical feature of this creation. In the legend of this case, only sketches and brief texts are used to give a brief description.

The cold shrinkable film hooding machine 10 is composed of a frame 11 and a film-hanging assembly (not shown) carried on the frame 11 , a film feeding assembly 13 , a heat-sealing film cutting assembly 14 , a film opening assembly 15 , and a film assembly 16 . The four membrane components 16 can move up and down along the frame 11, and each of the four membrane components 16 is provided with a stretch membrane component 17. The cold-shrinkable film is a bag-shaped body with a closed top and an open bottom, and is stretched on the stretching film assembly 17 . The object 35 to be coated is carried by the pallet 36, and is carried into the above-mentioned coating machine via a conveying device. The stretching film assembly 17 simultaneously stretches the cold shrinkable film outwards so that its covering area is slightly larger than the lateral area of the object 35 . The film covering assembly 16 moves down together with the spreading film assembly 17 to wrap the cold shrinkable film on the outside of the object 35 , and the cold shrinkable film finally covers the outside of the object 35 in a contracted and tight state. The cover film assembly 16 and the expansion film assembly 17 are separated from the cold shrinkable film, and then moved upwards to reset.

The creative object turning mechanism 20 includes: a pair of clamping claws 21 , a first actuating device 23 , a second actuating device 24 , a third actuating device 25 , and a turning device 26 .

The two jaws 21 respectively include a main body 211, and a gripper is respectively set on the upper and lower sides of the main body 211. Buckle 212. Preferably, the main body 211 is a plate-like structure. The buckle portion 212 is bent along the upper and lower sides of the plate structure to form a shovel shape.

The first actuating device 23 controls the two jaws 21 to move relative to each other or away from each other. The two jaws 21 moving relative to each other can generate a clamping force. The first actuating device 23 includes but not limited to hydraulic, or pneumatic, or mechanical actuation assemblies.

The second actuating device 24 controls the vertical movement of the two clamping jaws 21 and the first actuating device 23 . The moving distance is about 40 to 60 cm. The second actuating device 24 includes but not limited to hydraulic, or pneumatic, or mechanical linear actuation assemblies.

As shown in Figure 4, step 1, object positioning. The object 35 to be coated is lined with a first cardboard 31 on the bottom surface and carried by a pallet 36, and then moved into the coating position in the above-mentioned coating machine via a conveying device (not shown).

As shown in Figure 5, step 2, place the second cardboard 32. A second cardboard 32 is placed on the top surface of the object 35 by a robot arm (not shown).

As shown in Figure 6, step 3, the first coat. This cover film component 16 goes toward this expansion film component 17 together with Moving down, the first layer of cold-shrinkable film 33 is placed on the outside of the second cardboard 32 and the peripheral surface (four sides) of the object 35 to form the first film-coated object. The first layer of cold shrink film 33 does not cover the first cardboard 31 and the pallet 36 . After the mantle, the mantle component 16 moves upward together with the stretch film component 17 and resets.

As shown in FIG. 7 and FIG. 8 , in step 4, the clamping jaw 21 grips the first coating object. The third actuating device 25 controls the two jaws 21 to enter the shrink film hood machine 10 . The first actuating device 23 controls the relative movement of the two jaws 21 to clamp the two sides of the first coating object, and the upper and lower two grasping parts 212 of the two jaws 21 grasp and buckle the first cardboard 31 and the second cardboard 32.

As shown in Fig. 9 and Fig. 10, step 5, elevate the film object for the first time. The second actuating device 24 lifts the two clamping jaws 21, the first actuating device 23 and the first-time coating object by 40 to 60 centimeters, so that the first-time coating object leaves the pallet 36.

As shown in Fig. 11 and Fig. 12, in step 6, turn over the first coating object. The turning device 26 controls the two jaws 21 to turn 180 degrees. The first time the coating object is turned over 180 degrees, and the first cardboard 31 is turned to the top surface.

FIG. 13 , step 7, put the filmed object back into the pallet 36 for the first time. The second actuating device 24 moves the two clamping jaws 21 , the first actuating device 23 and the first-time coating object downwards, and puts the first-time coating object back on the pallet 36 . Afterwards, the first actuating device 23 controls the two clamping jaws 21 to move away from the first coating object. The third actuating device 25 controls the two jaws 21 to leave the shrink film hood machine 10 .

Figure 14, step 8, the second coat. The film covering assembly 16 moves down together with the spreading film assembly 17, and the second layer of cold shrinkable film sleeve 34 is placed on the outside of the first cardboard 31 and the first film covering object to form a second film covering object. The object 35 , the first cardboard 31 and the second cardboard 32 are covered by a first layer of cold-shrinkable film sleeve 33 and a second layer of cold-shrinkable film sleeve 34 . The full surface (top, bottom and all perimeters) of object 35 surface) are covered with cold shrink film.
