Description

Technical Field

[0001] The utility model relates to the technical field of printing die-cutting, in particular to a circular die-cutting machine air blowing knife roller. Background Technique

[0002] The circular die-cutting knife roller was first applied in the printing industry, especially in the cigarette package printing and packaging industry. It is a high-efficiency die-cutting tool that replaces the flat-bed die-cutting process.

[0003] During the production process of the circular die-cutting knife roller, a "sticking knife phenomenon" will occur. When the roller knife cuts the product, due to reasons such as the material being cut and the inertia generated by rotation, the product and the knife will rotate together. We call this phenomenon the "sticking knife phenomenon". This phenomenon often causes the products cut by customers to not effectively enter the next process. And in the traditional method, it is necessary to manually clean the residual materials in the circular die, which is inefficient and prone to errors, and is not conducive to production efficiency.

[0017] Compared with the prior art, the present utility model provides a rotary die cutter air blowing knife roller, which has the following beneficial effects:

[0018] 1. For this rotary die cutter air blowing knife roller, by starting the air pump, the air pump will eject gas from the air blowing holes. The gas ejected from the air blowing holes can take out the materials remaining in the rotary die cutter, which realizes automatic cleaning and improves production efficiency. Since the residual materials can be cleaned in time, the adverse effects caused by the materials in the next cutting are avoided, thereby improving the cutting accuracy and quality.

Specific implementation mode

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-3 , the present utility model provides a new technical solution: a circular die-cutting machine with air blowing knife roller, including a fixed roller 1 of circular die-cutting tool, the outer surface of the fixed roller 1 of circular die-cutting tool is provided with a plurality of circular die-cutting tools 2 for cutting materials, the plurality of circular die-cutting tools 2 are evenly arranged in a circumferential array, and a plurality of air blowing holes 3 are opened on the outer surface of the fixed roller 1 of circular die-cutting tool;

[0026] The plurality of air blowing holes 3 are respectively located in the corresponding circular die-cutting tools 2, and support covers 4 for connection and fixation are fixedly connected inside both ends of the fixed roller 1 of circular die-cutting tool, and connecting bushings 5 are fixedly connected inside both support covers 4;

[0027] An air blowing assembly is arranged on the fixed roller 1 of circular die-cutting tool, and the air blowing assembly is used to blow out the materials in the circular die-cutting tool 2 after cutting by the circular die-cutting tool 2. The air blowing assembly includes a main air blowing pipe 6, a mother sensor 11, a plurality of son sensors 13 and an electromagnetic control valve 14;

[0028] The main air blowing pipe 6 in the air blowing assembly is rotatably connected inside the two connecting bushings 5, the main air blowing pipe 6 is used to connect an external air pump, a plurality of branch air blowing pipes 7 adapted to the air blowing holes 3 are fixedly connected to the outer surface of the main air blowing pipe 6, and the branch air blowing pipes 7 are slidably connected to the inner wall of the fixed roller 1 of circular die-cutting tool.

[0029] Further, a dust shield cylinder 8 for blocking dust is fixedly sleeved on the outer surface of the main air jet pipe 6. The dust shield cylinder 8 is an open cylinder, and the dust shield cylinder 8 can block multiple air blowing holes 3 and only leave the group of air blowing holes 3 at the lower side. The dust shield cylinder 8 is rotatably connected to the inner wall of the rotary die cutter fixing roller 1.

[0030] Further, one end of the rotary die cutter fixing roller 1 is fixedly connected with a plurality of sub-sensor fixing seats 12 that are matched with the positions of the corresponding rotary die cutters 2, and the sub-sensors 13 are respectively fixedly installed on the plurality of sub-sensor fixing seats 12.

[0031] Further, one end of the main air jet pipe 6 extends out of the outer surface of the side connecting bushing 5 and is fixedly sleeved with a mother-sensor fixing seat 10 for fixing the mother-sensor 11, and the mother-sensor 11 is fixedly installed on the mother-sensor fixing seat 10.

[0032] Further, the mother-sensor fixing seat 10 is adapted to a single sub-sensor 13, and the electromagnetic control valve 14 is arranged at one end of the main air jet pipe 6 close to the mother-sensor 11.

[0033] Further, the mother-sensor 11 is electrically connected to the electromagnetic control valve 14. The electromagnetic control valve 14 is used to control the air jet of the air jet branch pipe 7 to the air blowing holes 3. Bearings 9 for installation and fixation are sleeved at both ends of the connecting bushing 5.

[0034] Further, during use, by starting the air pump, the air pump jets air into the main air jet pipe 6. When the rotary die cutter 2 on the lower working area of the rotary die cutter fixing roller 1 cuts the material, due to the fact that the positions of the arranged sub-sensor fixing seats 12 correspond to the rotary die cutters 2, this enables the corresponding sub-sensors 13 to be adapted to the mother-sensor 11 and emit signals when the rotary die cutter 2 cuts the material, so that the mother-sensor 11 can send signals to the electromagnetic control valve 14, and the electromagnetic control valve 14 immediately opens. At this time, the air jetted by the air pump into the main air jet pipe 6 will be jetted into the air jet branch pipe 7, and at this time the air jet branch pipe 7 will just blow air into the rotary die cutter 2 in the rotary die cutter 2 in the lower working area, so as to eject the gas from the air blowing holes 3. The gas ejected from the air blowing holes 3 can take out the material remaining in the rotary die cutter 2, which realizes automatic cleaning and improves production efficiency. Since the residual material can be cleaned in time, the adverse effects caused by the material during the next cutting are avoided, thereby improving the cutting accuracy and quality, and also avoiding the problems of low efficiency and easy error in the traditional method of manually cleaning the residual material in the rotary die cutter 2.

[0035] Furthermore, after the rotary die cutter 2 finishes cutting the material, since the corresponding sub-sensor 13 is separated from the mother sensor 11, the electromagnetic control valve 14 can be immediately closed, which prevents the gas from escaping from anywhere other than the air blowing holes 3. This not only avoids unnecessary energy waste but also enables the air blowing assembly to control the air flow more precisely. The air is only ejected when cleaning is required, thus avoiding unnecessary energy waste, reducing the waste generated during cleaning, and avoiding the accidental risks brought by the continuous turbulent ejection of gas. To a certain extent, the stability of the air blowing cutter roller during use is improved.

[0036] Working principle: During use, the air pump is started, and the air pump jets air into the main air jet pipe 6. When the rotary die cutter 2 located in the lower working area on the rotary die cutter fixed roller 1 cuts the material, due to the position of the sub-sensor fixing seat 12 being corresponding to the rotary die cutter 2, when the rotary die cutter 2 cuts the material, the corresponding sub-sensor 13 can be adapted to the mother sensor 11 and emit a signal, enabling the mother sensor 11 to send a signal to the electromagnetic control valve 14. The electromagnetic control valve 14 immediately opens. At this time, the air jetted by the air pump into the main air jet pipe 6 will be ejected into the air jet branch pipe 7, and at this time, the air jet branch pipe 7 will just jet air into the rotary die cutter 2 within the rotary die cutter 2 in the lower working area, so as to eject the gas from the air blowing holes 3. The gas ejected from the air blowing holes 3 can carry out the material remaining in the rotary die cutter 2.

[0037] Furthermore, after the rotary die cutter 2 finishes cutting the material, since the corresponding sub-sensor 13 is separated from the mother sensor 11, the electromagnetic control valve 14 can be immediately closed, which prevents the gas from escaping from anywhere other than the air blowing holes 3. This not only avoids unnecessary energy waste but also enables the air blowing assembly to control the air flow more precisely.

[0038] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
