Description

Technical Field

[0001] This utility model relates to the technical field of sponge strip application mechanism, and in particular to a sponge strip application mechanism and an automatic sponge strip application machine. Background Technology

[0002] With the rapid development of the packaging and printing industry, the requirements for die-cutting laser cutting templates are becoming increasingly stringent. Whether it's automated color box packaging or carton die-cutting packaging, die-cutting templates are essential. Manually applying elastic foam to the die-cutting plate is no longer sufficient, as it suffers from low efficiency and high labor costs; this is a major pain point for the die-cutting departments of many packaging and printing companies. Currently, some simple structures on the market can replace manual application of foam strips, but their low level of automation still has significant drawbacks. The process involves first cutting foam strips of the corresponding shape from a whole foam board according to requirements, and then using a foam strip application mechanism to grab and apply them to the die. Currently, existing sponge strip application mechanisms can only cut short or simple sponge shapes, resulting in poor material-saving effects when splicing. The more short or simple sponge shapes are cut, the more wasteful the sponge material becomes. Furthermore, cutting short or simple sponge shapes leads to low efficiency in gripping and applying sponge strips, failing to meet the production needs of the current packaging and printing industry. Therefore, considering these shortcomings, a dedicated sponge strip application mechanism needs to be developed to solve the difficulty of gripping irregularly shaped sponges, improve material control, and increase efficiency. Thus, a sponge strip application mechanism and an automatic sponge application machine are provided to solve the aforementioned problems. Utility Model Content

In this embodiment, two first lifting cylinders 222 are fixedly mounted on the support plate 211 and drive-connected to the pressure plate body 221 respectively. In other embodiments, the number of first lifting cylinders 222 can be one, three, four, or other plurality, and the number can be set according to actual needs.

[0034] Please see Figures 3-5 As shown, specifically, the pressure plate body 221 is provided with at least one first connecting hole 2211, multiple second connecting holes 2212, multiple pressure needle holes 2213, and multiple grasping needle holes 2214.

[0037] This utility model discloses an automatic sponge applicator, which includes the sponge strip applicator 100 described above.

[0038] It should be noted that the specific working process of the sponge strip applicator and automatic sponge applicator of this utility model is as follows: the transfer component 10 drives the sponge strip applicator 20 to move directly above the irregularly shaped sponge strip 30 to be grasped. At this time, multiple elastic pressure pins 23 extend out of the pressure plate body 221 respectively. The lifting drive mechanism 12 drives the sponge strip applicator 20 to move downward, and the multiple elastic pressure pins 23 move downward simultaneously to press the multiple irregularly shaped sponge strips 30. Then, the multiple second lifting cylinders 241 corresponding to the irregularly shaped sponge strips 30 to be grasped synchronously drive the multiple grasping pin bodies 242 to move downward, and the multiple grasping pin bodies 242 complete the grasping operation of the irregularly shaped sponge strips 30 to be grasped. The lifting drive mechanism 12 drives the sponge strip attaching assembly 20 to move upward. At this time, multiple elastic pressure pins 23 release the pressing operation on multiple irregularly shaped sponge strips 30. Simultaneously, the corresponding multiple gripping needle bodies 242 drive the gripped irregularly shaped sponge strips 30 to move upward as well. Then, the lifting drive mechanism 12 and the rotation drive mechanism 14 cooperate to transfer the sponge strip attaching assembly 20 to the designated position. The first lifting cylinder 222 drives the pressure plate body 221 to move downward, thereby attaching the gripped irregularly shaped sponge strips 30 to the designated position. At the same time, multiple second lifting cylinders 241 synchronously drive multiple gripping needle bodies 242 to move upward, thereby completing the automatic gripping and attaching operation of the irregularly shaped sponge strips 30, and repeating the cycle.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the embodiments are described.
