Description

Technical Field

[0001] The invention relates to the technical field of drum inner membrane attachment, and in particular to a mechanism for continuously and synchronously pressing the inner wall of a drum body. Background Art

[0002] After the welding ears of the existing packaging barrels are assembled, it is necessary to attach a film to the welding ear position of the inner wall of the barrel. The existing attaching method, whether manual or machine, only performs single or double pressure attaching. After the attaching force is removed, the thin wall may not be able to completely adhere to the barrel wall. Therefore, it is necessary to manually check and repair the film that is not attached in place at the subsequent workstation, which makes the attaching efficiency low and cannot meet the production needs. Summary of the invention

[0003] In view of the above problems, the present invention provides a mechanism for continuously and synchronously pressing the inner wall of the barrel body, 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.

[0004] A barrel inner wall continuous synchronous pressing mechanism, characterized in that it comprises:

[0005] A runway-type track conveyor belt, comprising an upper straight section, a lower straight section, and two arc-shaped connecting ends;

[0006] Continuous conveyor belts;

[0007] and a plurality of pre-pressing follower pressing head assemblies, which include a pressing head mounting frame, a cam assembly, and pressing heads on both sides, wherein mounting seats of the pressing head are respectively embedded with guide rails on both sides of the horizontal surface of the pressing head mounting frame, and a contraction spring is further arranged between the mounting seat and the pressing head mounting frame, wherein the contraction spring causes the side portion of the pressing head in a non-working state to retract inwardly to the corresponding side end of the pressing head mounting frame, and a cam assembly is arranged in the middle area facing each other between the two mounting seats, and when the large diameter end of the cam is plugged in the area between the two mounting seats, the pressing heads on both sides protrude from the corresponding side ends of the pressing head mounting frame;

[0008] A runway-type track conveyor belt is arranged above the continuous conveyor belt, and a plurality of pre-pressing and following pressing and attaching head assemblies are arranged at equal intervals on the outer circumference of the runway-type track conveyor belt, and when each of the pre-pressing and following pressing and attaching head assemblies is located in the lower straight section, the pressing and attaching head sides on both sides protrude from the corresponding side ends of the pressing and attaching head mounting frame;

[0009] The continuous conveyor belt and the runway-type track conveyor belt are set to the same linear running speed, and each of the pre-pressing follow-up pressing head components is arranged one by one corresponding to the barrel body on the continuous conveyor belt.

[0010] It is further characterized by:

[0011] The width direction of the runway-type track conveyor belt corresponds to the lower straight section and is provided with a downward convex guide block, which is used to drive the cam assembly to move downward, thereby driving the side convexities of the pressing heads on both sides to follow and press the film on the inner wall of the barrel body;

[0012] 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 does not bulge out laterally.

[0013] The pressing head includes a profiling head and a pressing sponge. The pressing sponge is coated on the outer surface of the profiling head. The surface area of ​​the pressing sponge is not smaller than the surface area of ​​the film, so as to ensure stable and reliable pressing.

[0014] The two sides of the continuous conveyor belt are also provided with second baking mechanisms, which are arranged at the corresponding height positions of the welding ears of the products;

[0015] The second baking mechanism is arranged in a long strip shape and is continuously arranged along the length direction of the continuous conveyor belt. It fully heats the film attachment area of ​​the welding ear to ensure stable and reliable attachment.

[0016] After the present invention is adopted, after the inner wall of the welding ear position of the barrel body is attached with a film, the barrel body is conveyed to the continuous conveyor belt by the front stepping claw. At this time, the corresponding pre-pressure following pressure attachment head assembly is guided into the barrel body through the arc-shaped connecting end, and through the action of the cam assembly, the pressure attachment heads on both sides are convex, and then the pressure attachment heads are respectively pressed onto the film. Since the continuous conveyor belt and the runway-type track conveyor belt are set with the same straight-line running speed, the pressure attachment heads continue to press the film onto the inner wall in the area of ​​the lower straight section until the pre-pressure following pressure attachment head assembly is separated from the lower straight end, at which time the cam assembly retracts and the pressure attachment head retracts laterally. At this time, the pre-pressure following pressure attachment head assembly is guided to separate from the barrel body area through the arc-shaped connecting end at the other end, and a continuous pressure is applied 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.

DETAILED DESCRIPTION

[0026] A mechanism for continuously and synchronously pressing the inner wall of a barrel, see Figure 1-Figure 7 , which includes a runway-type track conveyor belt 10, a continuous conveyor belt 20, and a plurality of pre-pressing and following pressing head assemblies 30;

[0027] The runway-type track conveyor belt 10 includes an upper straight section 11, a lower straight section 12, and two arc-shaped connecting ends 13; it also includes a power motor 14 and a track-type frame 15. The output end of the power motor 14 is meshed and connected to the runway-type track conveyor belt 10 through a transmission wheel 16.

[0028] Each pre-pressing follower pressing head assembly 30 includes a pressing head mounting frame 31, a cam assembly 32, and pressing heads 33 on both sides. The pressing head mounting seats 35 are respectively embedded with the pressing head mounting frame 31 through the guide rails 34 on both sides of the horizontal surface. A contraction spring 36 is also arranged between the mounting seat 35 and the pressing head mounting frame 31. The contraction spring 36 makes the side of the pressing head 33 in the non-working state shrink inward to the corresponding side end of the pressing head mounting frame 31. The cam assembly 32 is arranged in the middle area facing the two mounting seats 35. When the large diameter end of the cam 38 is plugged in the area between the two mounting seats 35, the pressing heads 33 on both sides protrude from the corresponding side ends of the pressing head mounting frame 31.

[0029] Both sides of the track-type frame 15 are fixed to the frame 50 supported by the continuous conveyor belt 20 through the side brackets 40, so that the assembly of the structure is stable and reliable;

[0030] A runway-type track conveyor belt 10 is arranged above the continuous conveyor belt 20. A plurality of convex connecting frames 60 are arranged at equal intervals on the outer periphery of the runway-type track conveyor belt 10. Pre-pressing follow-up pressing head assemblies 30 are fixedly mounted on the outer ends of the convex connecting frames 60. When each pre-pressing follow-up pressing head assembly 30 is located at the lower straight section 12, the pressing heads 33 on both sides are convex to the corresponding side ends of the pressing head mounting frame 31.

[0031] The continuous conveyor belt 20 and the runway-type track conveyor belt 10 are set to the same linear running speed, and each pre-pressing follower pressing head assembly 30 is arranged one-to-one corresponding to the barrel body 70 on the continuous conveyor belt 20 .

[0032] When implementing:

[0033] A downward convex guide block 80 is provided in the direction of the width of the runway-type track conveyor belt 10 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, and to follow the film pressed against the inner wall of the barrel body 70. The upper part of the downward convex guide block 80 is fixedly mounted at the lower position of the track-type frame 15.

[0034] The linear connection end 321 of the cam assembly 32 is connected to the corresponding position of the pressing head mounting frame 31 through a linear spring 322. When the cam assembly 32 is not pressed by the lower convex guide block 80, the linear spring is used to retract the cam assembly 32 to ensure that the pressing head 33 does not bulge outward.

[0035] The pressing head 33 includes a profiling head 331 and a pressing sponge 332. The pressing sponge 332 is coated on the outer surface of the profiling head 331. The surface area of ​​the pressing sponge 332 is not smaller than the surface area of ​​the film, so as to ensure stable and reliable pressing.

[0036] The two sides of the continuous conveyor belt 20 are also provided with second baking mechanisms 90, which are arranged at the corresponding height position of the welding ears of the product;

[0037] The second baking mechanism 90 is arranged in a long strip shape and is continuously arranged along the length direction of the continuous conveyor belt. It fully heats the film attachment area of ​​the welding ear to ensure stable and reliable attachment.

[0038] In a specific implementation, baffle structures 21 are arranged on both sides of the continuous conveyor belt 20 to ensure that the barrel body will not deviate in the width direction.

[0039] Its working principle is as follows: after a film is attached to the inner wall of the welding ear position of the barrel body, the barrel body is transported to the continuous conveyor belt by the front stepping claw. At this time, the corresponding pre-pressure following pressure attachment head assembly is guided into the barrel body through the arc-shaped connecting end, and through the action of the cam assembly, the pressure attachment heads on both sides are convex, and then the pressure attachment heads are respectively pressed onto the film. Since the continuous conveyor belt and the runway-type track conveyor belt are set with the same linear running speed, the pressure attachment head continues to press the film to the inner wall in the area of ​​the lower straight section until the pre-pressure following pressure attachment head assembly is separated from the lower straight end, at which time the cam assembly retracts and the pressure attachment head retracts laterally. At this time, the pre-pressure following pressure attachment head assembly is guided to separate from the barrel body area through the arc-shaped connecting end at the other end, and it applies a 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.
