Description

A continuous synchronous pressing mechanism for the inner wall of the barrel

Technical field

The invention relates to the technical field of drum inner film sticking, specifically a mechanism for continuous and synchronous pressing of the inner wall of the barrel.

Background technique

After the welding ears of existing packaging barrels are assembled, a film needs to be affixed to the welding ears on the inner wall of the barrel. The existing affixing method, whether it is manual affixing or machine affixing, only performs single or twice pressure affixing. , and then after removing the adhesion force, the thin wall may not completely fit the barrel wall. For this reason, it is necessary to repair the film that is not adhered in place after manual inspection at the subsequent work station, which makes the lamination efficiency low and cannot meet the production requirements. need.

Contents of the invention

In response to the above problems, the present invention provides a mechanism for continuous and synchronous pressing of the inner wall of the barrel, which applies continuous pressure after the film is attached to the inner wall to ensure that the film is completely attached to the inner wall, thereby improving production efficiency.

The contraction spring causes the side of the pressure attachment head in the non-working state to contract inward at the corresponding side end of the pressure attachment head mounting frame. A cam assembly is provided in the opposing middle area of the two mounting seats. When the large diameter end of the cam is plugged into the area between the two mounting seats, the press-fitting heads on both sides protrude from the press-fitting head.

A number of pre-pressure and follow-up pressure attachment head assemblies are arranged at equal intervals on the outer periphery of the runway-type orbit conveyor belt. Each of the pre-pressure follow-up pressure attachment head assemblies is located at a certain location. When the lower straight section is described, the press-attachment heads on both sides protrude from the corresponding side ends of the press-attachment head mounting frame;

The continuous conveyor belt and the track-type track conveyor belt are set to the same linear running speed, and each of the pre-pressure follower pressing head assemblies is arranged one-to-one corresponding to the barrels on the continuous conveyor belt.

It is further characterized by:

The track-type conveyor belt is provided with a downward convex guide block in a width direction corresponding to the lower straight section. The downward convex guide block is used to drive the cam assembly to move downward, thereby driving the lateral convexities of the pressing heads on both sides. Follow the film pressing against the inner wall of the barrel;

The linear connection end of the cam assembly is connected to the corresponding position of the pressing head mounting frame through a linear spring. When the cam assembly is not pressed by the lower convex guide block, it is retracted under the action of the linear spring to ensure that the pressing head is pressed. The appendage does not bulge;

The pressing head includes a profiling head and a pressing sponge. The pressing sponge covers the outer surface of the profiling head. The area of the pressing sponge is not smaller than the area of the film, ensuring stable and reliable pressing;

The second baking mechanism is arranged in a strip shape and is continuously arranged along the length direction of the continuous conveyor belt. It fully heats the film pasting area of the welding lug to ensure stable and reliable pasting.

After adopting the present invention, after the inner wall of the welding ear position of the barrel is pasted with a film, the barrel is transported to the continuous conveyor belt by the front stepping claw. At this time, the corresponding pre-pressure follows the pressing head assembly through the arc. The shaped connection end is guided into the barrel, and through the action of the cam assembly, the pressing heads on both sides are convex, and then the pressing heads are pressed to the film respectively. Since the continuous conveyor belt and the runway-type track conveyor belt are set up to run in the same straight line speed, so that in the area of the lower straight section, the pressing head continues to press the film to the inner wall until the pre-pressure follows the pressing head assembly and breaks away from the lower straight end. At this time, the cam assembly retracts and the pressing head retracts laterally. At this time, the pre-pressure follower assembly is guided away from the barrel area through the arc-shaped connecting end at the other end. It applies continuous pressure after the film is attached to the inner wall to ensure that the film fully adheres to the inner wall, thus improving production efficiency.

At the side end, a cam assembly 32 is provided in the opposite middle area of the two mounting seats 35. When the large diameter end of the cam 38 is plugged into the area between the two mounting seats 35, the pressing heads 33 on both sides protrude from the pressing area.

In specific implementation:

The track-type conveyor belt 10 is provided with a downward convex guide block 80 in a width direction corresponding to the lower straight section 12. The downward convex guide block 80 is used to drive the cam assembly 32 to move downward, thereby driving the pressing heads 33 on both sides to convex sideways. Used to follow the film pressed against the inner wall of the barrel 70, the upper part of the downward convex guide block 80 is fixed at the lower position of the rail-type frame 15;

The linear connecting end 321 of the cam assembly 32 is connected to the corresponding position of the pressing head mounting bracket 31 through the linear spring 322.

During specific implementation, baffle structures 21 are also arranged on both sides of the continuous conveyor belt 20 to ensure that the barrel body will not shift in the width direction.

Its working principle is as follows. After the inner wall of the barrel's welding lug is pasted with a film, the barrel is transported to the continuous conveyor belt by the front stepping claw. At this time, the corresponding pre-pressure follows the pressing head assembly through the arc. The shaped connection end is guided into the barrel, and through the action of the cam assembly, the pressing heads on both sides are convex, and then the pressing heads are pressed to the film respectively. Since the continuous conveyor belt and the runway-type track conveyor belt are set up to run in the same straight line speed, so that in the area of the lower straight section, the pressing head continues to press the film to the inner wall until the pre-pressure follows the pressing head assembly and breaks away from the lower straight end. At this time, the cam assembly retracts and the pressing head retracts laterally. At this time, the pre-pressure follower assembly is guided away from the barrel area through the arc-shaped connecting end at the other end. It applies continuous pressure after the film is attached to the inner wall to ensure that the film fully adheres to the inner wall, thus improving production efficiency.
