Description

Technical Field

[0001] The utility model generally relates to the technical field of book production, in particular to a release paper peeling and tearing device and a bundling machine. Background Art

[0002] As a decorative and protective element of books, the waistband (also known as belt) can not only protect the cover of the book from wear and tear during transportation and use, but also increase the publicity effect of the book through its design and information transmission. However, the assembly of the waistband requires precise and efficient automated equipment, which involves the application of strapping machines.

[0003] In existing strapping machines, a glue coating device is usually equipped to evenly apply glue on one end of the girdle to ensure that the girdle can be firmly adhered to the book. However, this method is not only inefficient, but also easily causes glue to overflow, thereby contaminating the book cover. In order to overcome these problems, a feasible solution is to use a girdle material pre-coated with glue, and the surface of this girdle material is usually covered with a layer of release paper to keep the glue fresh and clean.

[0004] In order to effectively use this pre-glued girdle material in the book assembly process, a new type of equipment needs to be developed to facilitate the peeling of the release paper on the girdle during the installation process.

Specifically, the first suction cup 110 and the second suction cup 120 can be vacuum suction cups. A first suction nozzle 111 and a second suction nozzle 112 are arranged at intervals on the upper side of the first suction cup 110, and the waist seal material can be firmly sucked by the first suction nozzle 111 and the second suction nozzle 112 to prevent the waist seal material from shifting. Optionally, the first suction nozzle 111 and the second suction nozzle 112 are respectively arranged at both ends of the first suction cup 110. The second suction cup 120 is arranged above the first suction cup 110, and one or more third suction nozzles 121 are arranged on the lower side of the second suction cup 120. The third suction nozzles 121 can firmly suck the release paper on the waist seal material, so that the second suction cup 120 can peel off the release paper on the waist seal material under the drive of the mechanical arm 130. Optionally, one or more second suction cups 120 can be provided, and multiple second suction cups 120 can work alternately to improve the peeling efficiency. Each second suction cup 120 is respectively connected to the mechanical arm 130, and the mechanical arm 130 is configured to synchronously drive all the second suction cups 120 to rotate around the first axis.

In the process of peeling the release paper, the carrier 340 can provide good support for the waist seal material to prevent the waist seal material from being deformed or displaced under the pressure of the second suction cup 320.

[0046] In some strapping machines, the carrier 340 can be set to be movable to play a role in different process steps. For example, the carrier 340 can be set on a turntable and switch the workstation by rotating with the turntable.

The second linear actuator 350 may be, for example, an actuator such as a cylinder, a hydraulic cylinder, or an electric push rod. The second linear actuator 350 is arranged in the vertical direction, and its output module (such as a cylinder rod) is fixedly connected to the first suction cup 310. The second linear actuator 350 may drive the first suction cup 310 to rise and fall in the vertical direction as required, thereby cleverly avoiding the carrier 340 and preventing interference between the first suction cup 310 and the carrier 340. Optionally, the release paper peeling device may further include a support portion 360, and the second linear actuator 350 is mounted on the support portion 360.
