[0026] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The preferred embodiments of the present application are shown in the drawings. However, the present application can be realized in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0027] It should be noted that when an element is referred to as being "fixed" to another element, it can be directly on the other element or there can be an intervening element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be an intervening element.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the description of the present application herein only for the purpose of describing specific embodiments of the present application, and is not intended to limit the present application.

[0029] Please refer to Figures 1 to 6 The present application is a kind of paper box flexographic punching equipment, including machine 10, positioning assembly 20 installed on the top surface of machine 10, and punching assembly 30 installed above positioning assembly 20. Among them, positioning assembly 20 is used to position clamping first flexographic process strip 41 and second flexographic process strip 42;First flexographic process strip 41 and second flexographic process strip 42 are respectively independently made to form, so simultaneous punching is needed, to ensure that the printed pattern can match the corresponding.

[0030] The positioning assembly 20 comprises two channels 21 installed side by side on the top surface of the machine table 10, photoelectric sensors 22 installed at opposite ends of each channel 21, a push plate 23 slidingly installed at one end of the two channels 21, and a micrometer 24 connected to the push plate 23. The two channels 21 are used to position the first and second flexographic process strips 41 and 42, respectively. The push plate 23 is spaced apart from the channels 21, and the micrometer 24 is used to drive the push plate 23 to approach or move away from the channels 21 to adjust the distance between the push plate 23 and the channels 21, thereby adapting to the length requirements of different flexographic process strips.

[0031] In this embodiment, the push plate 23 is connected to the top surface of the machine table 10 through a guide rail pair.

[0032] The machine table 10 is provided with through holes 11 at opposite ends corresponding to each channel 21, and the bottom surface of the machine table 10 is further connected with a waste guide 12 below the through holes 11, and the bottom end of the machine table 10 is provided with a collection disc 13 below each waste guide 12.

[0033] The die cutting assembly 30 comprises a bracket 31 installed on the top surface of the machine table 10, a first lifting plate 32 slidingly installed on one side of the bracket 31, a second lifting plate 33 slidingly installed on the other side of the bracket 31, two first pressing plates 34 elastically connected to the bottom surface of the first lifting plate 32, first cutting knives 35 installed at opposite ends of each first pressing plate 34, two second pressing plates 36 elastically connected to the bottom surface of the second lifting plate 33, second cutting knives 37 installed at one end of each second pressing plate 36 away from the first pressing plate 34, a first die cutting cylinder 38 installed on one side of the top surface of the bracket 31, and a second die cutting cylinder 39 installed on the other side of the top surface of the bracket 31. The piston rod of the first die cutting cylinder 38 is connected to the first lifting plate 32 downward after penetrating the top surface of the bracket 31, and the piston rod of the second die cutting cylinder 39 is connected to the second lifting plate 33 downward after penetrating the top surface of the bracket 31.

[0034] In this embodiment, the first pressing plate 34 corresponds to the second pressing plate 36 one by one, and the length of the first pressing plate 34 is less than the length of the second pressing plate 36.

[0035] In actual use, since the distance between the push plate 23 and the first and second cutting knives 35 and 37 can be calculated, the distance between the push plate 23 and the channels 21 is accurately adjusted by the micrometer 24 in advance according to the specific length of the first and second flexographic process strips 41 and 42 to be cut.

[0036] Then, the first and second rubber plate process strips 41 and 42 are respectively placed in the inside of the channel 21, and it is ensured that the first and second rubber plate process strips 41 and 42 abut against the push plate 23. At this time, the photoelectric sensor 22 detects the positions of the first and second rubber plate process strips 41 and 42 respectively, and further confirms whether they are aligned.

[0037] Then, the first cutting cylinder 38 drives the first lifting plate 32 to fall, and the first pressing plate 34 abuts against and presses the first and second rubber plate process strips 41 and 42 respectively. The first lifting plate 32 continues to fall until the first cutting knife 35 cuts the first and second rubber plate process strips 41 and 42 respectively to form a plurality of small sections of the first and second rubber plates. The first and second rubber plates have equal lengths and corresponding pattern positions.

[0038] After one cutting, the first cutting cylinder 38 drives the first lifting plate 32 to reset. The operator needs to manually push the first and second rubber plate process strips 41 and 42 to move forward in the inside of the channel 21 until they abut against the push plate 23. The above cutting operation is continued until the entire first and second rubber plate process strips 41 and 42 are completely cut into the required small sections.

[0039] When the tail ends of the first and second rubber plate process strips 41 and 42 have excess process edges, the second cutting cylinder 39 is started to cut the tail ends. Specifically, the second lifting plate 33 drives the second pressing plate 36 and the second cutting knife 37 to fall, press and cut the tail end portions of the first and second rubber plate process strips 41 and 42, so as to ensure that the tail ends of the first and second rubber plate process strips 41 and 42 are completely aligned, and further ensure that the last formed small sections also have equal lengths.

[0040] The waste produced in the cutting process is dropped to the collection disc 13 through the through hole 11 and the waste guide 12.

[0041] The above-described cutting device for carton rubber plates has simple structure and is convenient to use. The channel 21 is arranged side by side. Through the cooperation of the push plate 23 and the photoelectric sensor 22, the first and second rubber plate process strips 41 and 42 are aligned, the position of the final printed pattern is accurately matched, and the pattern misalignment problem that may occur in the traditional way is avoided.

[0042] The technical features of the above-described embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present disclosure.

[0043] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several modifications and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
