Description

Technical Field

[0001] This utility model relates to a positioning and differential compensation device for the colored inner frame paper of a high-speed packaging machine, belonging to the technical field of packaging equipment. Background Technology

[0002] Currently, the inner frame paper conveying mechanism of high-speed tobacco packaging machines does not have the function of positioning conveying. It can only realize the fixed-length conveying of the inner frame paper. If the inner frame paper is printed with patterns at a certain spacing, the conveying of the inner frame paper needs to be changed from fixed-length conveying to positioning conveying. However, the inner frame paper conveying mechanism of the current high-speed tobacco packaging machine can only perform fixed-length conveying and does not have the function of positioning conveying, which makes it difficult to meet the usage requirements. Utility Model Content

[0003] To overcome the above deficiencies, the technical problem to be solved by this utility model is to provide a high-speed packaging machine color inner frame paper positioning recognition and differential compensation device, which has color difference recognition and positioning conveying functions, thereby overcoming the deficiencies of the above-mentioned prior art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A high-speed packaging machine's color inner frame paper positioning recognition and differential compensation device includes an inner frame paper conveying mechanism, a planetary differential wheel device, a differential device power assembly, a color difference sensor, and an inner frame paper belt. The inner frame paper conveying mechanism includes a power input shaft, a dotted line knife backing roller, a dotted line knife roller, a lower paper feeding roller, an upper paper feeding roller, a dotted line knife roller support, an upper paper feeding roller support, an upper paper feeding roller input gear, an upper paper feeding roller gear, a dotted line knife roller input gear, and a dotted line knife roller gear. The planetary differential wheel device includes a differential wheel power input gear, a planetary differential wheel assembly, and a differential wheel power output gear. The differential device power assembly... The assembly includes a servo motor, a servo reducer, a servo motor power output gear, and a transition gear; the differential wheel power input gear is fixed on the power input shaft and meshes with the planetary differential wheel assembly; the planetary differential wheel assembly meshes with the differential wheel power output gear; the upper paper feed roller input gear is fixed on the lower paper feed roller, the upper paper feed roller gear is fixed on the upper paper feed roller, and the upper paper feed roller input gear meshes with the upper paper feed roller gear; the inner frame paper tape is installed between the upper and lower paper feed rollers; and the color difference sensor is installed above the inner frame paper tape.

[0006] As a preferred embodiment, color mark identification points and inner frame paper cutting lines are provided on the inner frame paper strip.

[0007] As a preferred embodiment, the spacing between the color mark recognition points is 36.6 mm or 32.4 mm.

[0008] Beneficial Effects: Compared with existing technologies, this utility model possesses color difference recognition and positioning conveying functions, effectively solving the technical problem that the inner frame paper conveying mechanism of existing high-speed tobacco packaging machines can only perform fixed-length conveying and cannot perform positioning conveying. It can be used to convey solid-color, unpatterned inner frame paper and patterned colored inner frame paper. This utility model has two inner frame paper conveying modes: fixed-length conveying and positioning conveying. Fixed-length conveying means that the length of the inner frame paper conveyed each time is a fixed value, such as conveying 36.6mm each time. In this utility model, as long as the servo motor of the differential device power assembly does not rotate, the fixed-length conveying of the inner frame paper can be achieved. Positioning conveying uses a color difference sensor to identify the marking points printed on the inner frame paper tape. The servo motor drives the planetary gear differential wheel assembly according to the two recognition points. During the inner frame paper conveying process, a differential value is input to change the conveying length of the inner frame paper, and variable-length conveying is completed according to the spacing of the recognition points on the inner frame paper tape.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Reference Figures 1-5This utility model provides an embodiment of a high-speed packaging machine's color inner frame paper positioning recognition and differential compensation device, mainly comprising five parts: an inner frame paper conveying mechanism 1, a planetary differential wheel device 2, a differential device power assembly 3, a color difference sensor 4, and an inner frame paper belt 5; wherein, the inner frame paper conveying mechanism 1 includes a power input shaft 6, a dotted line knife backing roller 7, a dotted line knife roller 8, a lower paper feeding roller 9, an upper paper feeding roller 10, a dotted line knife roller support 11, an upper paper feeding roller support 12, an upper paper feeding roller input gear 13, an upper paper feeding roller gear 14, and a dotted line knife roller input gear 15. The input gear 15 and the dotted line cutter roller gear 16 are included; the planetary differential gear device 2 includes a differential gear power input gear 17, a planetary differential gear assembly 18, and a differential gear power output gear 19; the differential device power assembly 3 includes a servo motor 20, a servo reducer 21, a servo motor power output gear 22, and a transition gear 23; color mark identification points 24 and inner frame paper cutting lines 25 are provided on the inner frame paper tape 5, and the spacing of the color mark identification points 24 is a fixed value, which is set to 36.6mm or 32.4mm in this example.

[0016] Working Principle: This utility model can realize two functions: fixed-length conveying and positioning conveying. When the inner frame paper tape 5 is solid color (without pattern), the fixed-length conveying function is used, that is, the conveying length is fixed each time (generally 36.6mm or 32.4mm). In this function, the servo motor 20 does not rotate and is in a locked state. When the inner frame paper tape 5 is printed with a pattern at a certain interval (generally 36.6mm or 32.4mm), the positioning conveying function is used. The positioning function uses the color difference sensor 4 to identify the color difference identification point 24 printed on the inner frame paper tape 5, and transmits the identification signal to the servo motor 20. Then the servo motor 20 rotates and inputs a differential amount to compensate for the error between the printing interval and the fixed-length conveying, ensuring that the inner frame paper tape 5 is conveyed according to the spacing of the printed pattern each time.

[0017] This invention has two sets of power inputs. The power for the entire system is input through the power input shaft 6, with the servo motor 20 serving as an auxiliary power source. Its function is to input a differential value to compensate for the error between the printing pattern and the inner frame paper conveying distance. The power input shaft 6 is powered by the main unit and uses an intermittent motion method to directly drive the dotted line cutter backing roller 7. The dotted line cutter roller input gear 15 drives the dotted line cutter roller 8 through the dotted line cutter roller gear 16. The dotted line cutter roller 8 and the dotted line cutter backing roller 7 rotate in opposite directions to complete the dotted line cutting on the inner frame paper tape 5.

[0018] The differential wheel power input gear 17 is fixed on the power input shaft 6, which transmits the main power to the planetary differential wheel assembly 18. The planetary differential wheel assembly 18 transmits the power to the differential wheel power output gear 19, which finally transmits the main power to the lower paper feed roller 9. The upper paper feed roller input gear 13 is fixed on the lower paper feed roller 9, and transmits the power to the upper paper feed roller 10 through the upper paper feed roller gear 13. The lower paper feed roller 9 and the upper paper feed roller 10 rotate in opposite directions, clamping the inner frame paper strip 5 and moving it forward, thereby realizing the fixed-length conveying of the inner frame paper strip 5.

[0019] During the conveying process of the inner frame paper tape 5, the color difference sensor 4 identifies the color mark identification point 24 on the inner frame paper tape 5 and transmits the signal to the servo motor 20. The servo motor 20 reduces and amplifies the torque through the servo reducer 21, and the servo motor power output gear 22 drives the planetary gear inside the planetary differential gear assembly 18 through the transition gear 24. The differential value is input to correct the error between the pattern printing distance and the fixed-length conveying on the inner frame paper tape 5, ensuring that each conveying is controlled according to the spacing between the printed patterns, thereby realizing the positioning and conveying of the inner frame paper.

[0020] To facilitate the installation of the inner frame paper tape 5, the dotted line knife roller bracket 11 is designed to be quick-opening, and the upper paper feed roller bracket 12 is also designed to be easy to open.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
