Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to a flag pushing unit. Background Art

[0002] In the process of cardboard book production, using push flags is one of the important means of transferring book pages or mounting pages. Push flags are usually used in conjunction with chain mechanisms to achieve the circulation of push flags and continuously push cardboard. Push flags are directly installed on the chain plates of the chain mechanism. Ideally, the angles of each push flag are consistent, but in actual installation, due to factors such as chain plate length error and shape error, some push flags have a small deviation, resulting in inconsistent angles, which affects the pushing effect of book pages.

[0031] Combine the following Figures 1 to 4 The embodiments of the present utility model are described.

[0032] This embodiment relates to a flag-pushing unit. Ideally, the pushing page 20 of the flag-pushing unit is in vertical contact with the book page. Normally, the pushing page 20 has the least impact on the book page when it is in a vertical direction. However, when the pushing page 20 is tilted forward or backward, it may push the edge of the book page tightly and damage the edge of the book page when it is in contact with the book page. The flag-pushing unit of this embodiment allows the angle of the pushing page 20 to be fine-tuned, so that when the chain plate has a shape error, the flag-pushing unit adjusts the angle of the pushing page 20, ensuring that the pushing page 20 of each flag-pushing unit is as close to vertical as possible.

[0033] The flag pushing unit in this embodiment includes:

[0034] A flag-pushing bracket 1, wherein the flag-pushing bracket 1 is provided with a connecting hole 10;

[0035] A push column 2, wherein the push column 2 includes a push page 20;

[0036] An adjustment structure is provided, wherein the adjustment structure connects the flag-pushing bracket 1 and the pushing column 2, and the adjustment structure is used to change the angle between the pushing page 20 and the vertical direction.

[0037] The flag pushing unit connects the flag pushing bracket 1 and the pushing column 2 through an adjustment structure, so that the angle between the pushing column 2 and the vertical direction can be adjusted. When the flag pushing unit is installed on each chain plate of the chain, it can be adjusted to adapt to the error of the chain plate to ensure that the angle between each pushing column 2 and the vertical direction remains consistent.

[0038] The adjustment structure includes a first screw hole 21, a second screw hole 22, a first through hole 11, a second through hole 12, a first screw 31, and a second screw 32. The first screw hole 21 and the second screw hole 22 are arranged on the push column 2 at vertical intervals. The first through hole 11 and the second through hole 12 are arranged on the flag-pushing bracket 1 at vertical intervals. The first screw 31 passes through the first through hole 11 and is threadedly connected to the first screw hole 21. The second screw 32 passes through the second through hole 12 and is threadedly connected to the second screw hole 22. At least one of the first screw 31 and the second screw 32 clamps and fixes the flag-pushing bracket 1 and the push column 2 together. The first screw 31 and the second screw 32 are arranged on the flag-pushing bracket 1 and the push column 2 at vertical intervals. Under normal conditions, the first screw 31 and the second screw 32 jointly clamp and fix the push column 2 and the flag-pushing bracket 1, thereby conveniently ensuring that the assembly states of each flag-pushing unit are consistent. When the chain plate of the chain mechanism does not fail, the push pages 20 of each flag-pushing unit can remain consistent. When the angle of the push page 20 cannot be aligned normally due to the shape and position error of the chain plate, the first screw 31 or the second screw 32 is loosened according to the angle to be adjusted to adjust the angle of the push page 20. Taking the first screw 31 located at the top and the second screw 32 located at the bottom as an example, when the first screw 31 and the second screw 32 are fully locked, the push page 20 tilts forward, that is, the top of the push page 20 tilts forward, and at this time, the lower side of the push page 20 needs to be adjusted to tilt forward to offset the tilt caused by the chain plate error. The specific operation is to unscrew the second screw 32, and the push column 2 tilts forward because the locking force at the first screw 31 is greater than the locking force at the second screw 32. The push column 2 can be made of hard materials such as stainless steel or conventional steel, or soft materials such as plastic and rubber. When soft materials such as plastic or rubber are used, the tilt caused by the change in the locking force of the first screw 31 and the locking force of the second screw 32 is more obvious.

[0039] When the flag pushing unit has an operation interference, since the flag pushing unit is connected to the chain, the chain is tensioned as a flexible structure in the operation state, and the flag pushing unit is easily deformed, loosened, etc. when it is subjected to a large resistance due to the interference. For this reason, the flag pushing bracket 1 is further provided with a first material reduction portion 13. After the first material reduction portion 13 is provided on the flag pushing bracket 1, the structural strength of the flag pushing unit is reduced, and the flag pushing unit is more likely to break when it is subjected to a large force when interference occurs, and it is not easy to transfer a large resistance to the chain, which can better avoid damage to the chain and reduce maintenance costs.

[0040] Specifically, the first material reduction portion 13 is a through hole. The first material reduction portion 13 is a through hole, which can effectively reduce the structural strength, and the through hole is flexible to process, and can be processed by mold forming, or by drilling, tying, etc. Further, the through hole is a round hole.

[0041] The first through hole 11 is a countersunk hole. The second through hole 12 is a countersunk hole. The first through hole 11 and the second through hole 12 are countersunk holes, and the heads of the first screw 31 and the second screw 32 can be hidden in the holes, which can provide better protection for the screws.

[0042] The push page 20 is arc-shaped. The arc-shaped structure of the push page 20 can reduce the pushing force on the paper page.

[0043] The push page 20 is semicircular. The push page 20 has a semicircular structure, and the structural strength of the push column 2 is higher and more durable.

[0044] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of the present invention.
