Description

Technical Field

[0001] The utility model relates to the technical field of food packaging processing, in particular to an automatic adjustable inkjet coding device. Background Art

[0002] In the food processing industry, the food processing date and food coding are particularly important. According to the requirements of the National Food and Health Department, the production date and food coding must be on the product packaging bag. Therefore, an inkjet printer is needed to print on the food packaging.

[0003] In the process of inkjet coding processing of existing inkjet coding devices for food packaging, although the height of the inkjet coding structure can be flexibly adjusted to meet the inkjet coding processing requirements of food packaging with different heights, usually the telescopic adjustment structure is directly used to adjust the height of the inkjet coding structure. During the operation of the device, there is often a lack of an auxiliary guiding structure, which may cause the telescopic adjustment structure to be worn due to non-vertical forces, and also affect the stability of the inkjet coding structure, thereby affecting the inkjet coding effect. Therefore, it cannot fully meet the usage requirements of people.

[0004] For example, the utility model with the publication number of CN 212979584 U discloses a food packaging inkjet printer. However, during the process of implementing the technical solution in the embodiment of the present application, the inventors of the present application found that the above technology has at least the following technical problems: The movement of the inkjet printer is driven by the telescopic movement of the electric telescopic rod controlled by a single-chip microcomputer to complete the printing of the food packaging by the inkjet printer. Since only the telescopic adjustment of the telescopic push rod is used to adjust the vertical position of the inkjet printer, there is no guiding structure for vertically guiding the inkjet printer during the adjustment process. Therefore, it is easy for the telescopic push rod to be worn due to non-vertical forces, so that the position of the inkjet printer is prone to deviation, which in turn affects the inkjet coding effect. Summary of the Utility Model

[0005] In view of this, aiming at the deficiencies of the prior art, the utility model provides an automatic adjustable inkjet coding device, which can not only meet the basic requirements of inkjet coding processing for food packaging with different heights, but also stably adjust the position of the inkjet coding structure, so that the device can continuously and stably perform inkjet coding processing on food packaging.

[0030] Example 1, such as Figure 1 、 2, as shown in FIGS. 3, an automatic adjustable inkjet coding device includes a mounting frame 101. Support legs 102 are provided at the bottom of the mounting frame 101. A conveyor belt 103 running in the left - right direction and driven by a servo motor 100 is provided at the top of the mounting frame 101. A plurality of vertical rods 104 are further provided at the top of the mounting frame 101 outside the conveyor belt 103. A top plate 105 is commonly provided at the tops of the plurality of vertical rods 104. A first telescopic push rod 106 is vertically provided on the top plate 105. The lower end of the output shaft of the first telescopic push rod 106 is provided with a mounting plate 107. An inkjet printer 108 is provided at the bottom of the mounting plate 107. A guiding sliding hole 109 is vertically provided at the top of the mounting plate 107 on the side of the first telescopic push rod 106. A guiding insertion plate 110 inserted and connected to the guiding sliding hole 109 is vertically provided at the bottom of the top plate 105. An adjustable inkjet drying module for drying the inkjet coding on food packaging is further provided at the bottom of the top plate 105.

[0031] As Figure 1 , 2 shown, the adjustable inkjet drying module includes a linear slide 201 arranged in the front - back direction at the bottom of the top plate 105 and on one side of the first telescopic push rod 106. A support sliding groove 202 is further arranged in the front - back direction at the bottom of the top plate 105 on the other side of the first telescopic push rod 106. A support sliding block 203 is slidably arranged in the front - back direction in the support sliding groove 202. A U - shaped plate 204 capable of being adjusted below the inkjet printer 108 is commonly provided between the slide seat of the linear slide 201 and the bottom of the support sliding block 203. A second telescopic push rod 205 is vertically provided on the U - shaped plate 204. The lower end of the output shaft of the second telescopic push rod 205 is provided with a fixing plate 206. A hot air blower 207 is vertically provided at the bottom of the fixing plate 206.

[0032] As Figure 1 , 3 shown, a guiding insertion rod 214 slidably connected to the U - shaped plate 204 is further vertically provided at the bottom of the fixing plate 206. A guiding insertion hole 215 adapted to the guiding insertion rod 214 is provided on the U - shaped plate 204.

[0033] As Figure 1 , 2 shown, an L - shaped fastening plate 303 is provided at the top of the hot air blower 207. A fastening bolt 304 for screwing and fixing to the fixing plate 206 is provided on the horizontal part of the fastening plate 303. A threaded fastening hole adapted to the fastening bolt 304 is provided on the fixing plate 206. The user can make the fastening bolt 304 pass through the horizontal part of the fastening plate 303 and be screwed and fixed to the threaded fastening hole, so as to realize the flexible fixation of the fastening plate 303 and the fixing plate 206, and then flexibly install the hot air blower 207 to the bottom of the fixing plate 206.

[0034] When a food package is conveyed to the position below the inkjet printer 108 through the conveyor belt 103, the conveyor belt 103 can be paused by the servo motor 100 so that the food package stays below the inkjet printer 108. Then, the output shaft of the first telescopic push rod 106 can be extended downward by a certain length. At the same time, under the guiding cooperation of the guiding insertion plate 110 sliding vertically relative to the guiding sliding hole 109, the inkjet printer 108 can be moved downward to a position close to the area to be inkjet-printed on the food package, so that the inkjet printer 108 performs inkjet printing on the food package. Subsequently, the output shaft of the first telescopic push rod 106 can be shortened upward by a certain length. At the same time, under the guiding cooperation of the guiding insertion plate 110 relative to the guiding sliding hole 109, the inkjet printer 108 can be reset and moved upward to a position higher than the U-shaped plate 204.

[0035] Then, the slide seat of the linear slide table 201 can be moved in the front-back direction. At the same time, when the support slider 203 slides relative to the support sliding groove 202, the U-shaped plate 204 can be moved to a position below the inkjet printer 108 and corresponding to the upper part of the inkjet-printed area of the food package. Subsequently, the output shaft of the second telescopic push rod 205 can be extended downward by a certain length so that the distance between the hot air blower 207 and the food package meets the position requirement for subsequent drying of the inkjet printing. Then, the hot air blower 207 can be started to blow hot air toward the inkjet printing on the food package to dry the inkjet printing on the food package, avoiding touching the printed code and production date subsequently and causing the problem of blurred text. Then, the hot air blower 207 can be paused, and the output shaft of the second telescopic push rod 205 can be shortened upward by a certain length to reset the hot air blower 207 upward. Then, the slide seat of the linear slide table 201 can be moved in the front-back direction. At the same time, when the support slider 203 slides relative to the support sliding groove 202, the U-shaped plate 204 can be moved to a position offset below the inkjet printer 108. In this way, the inkjet printing process and the drying process of the inkjet printing for a food package can be completed.

[0036] Then, the conveyor belt 103 can be continued to operate to convey the food package and perform inkjet printing and drying treatment after inkjet printing on subsequent food packages.

[0037] Embodiment 2, as Figure 4As shown, at the bottom of one side of the fixed plate 206, a connecting socket tube 208 is vertically arranged. A connecting plug rod 209 is vertically inserted into the connecting socket tube 208. At the bottom of the connecting plug rod 209, a pressing and fixing frame 210 is arranged. At the top of the pressing and fixing frame 210, a bearing 211 is also arranged. The other side of the fixed plate 206 is vertically penetrated and screwed with an adjusting screw rod 212. The lower end of the adjusting screw rod 212 is connected to the inner ring of the bearing 211. At the upper end of the adjusting screw rod 212, a turning handle 213 is screwed. When it is necessary to perform inkjet coding processing and drying treatment after inkjet coding on relatively light food packages, the adjusting screw rod 212 can be adjusted by turning the turning handle 213. With the cooperation of the bearing 211 and the guiding action of the connecting socket tube 208 and the connecting plug rod 209, the pressing and fixing frame 210 moves downward, so that the pressing and fixing frame 210 moves to a position at a certain distance below the hot air blower 207. Thus, when the user dries the inkjet code on the relatively light food package, the output shaft of the second telescopic push rod 205 can be extended downward by a certain length, so that the relatively light food package is limited and fixed by the pressing and fixing frame 210, avoiding the relatively light food package from easily shifting when drying the inkjet code on it, and making the height difference between the hot air blower 207 and the inkjet coding area of the food package meet the requirements of fast and efficient inkjet coding drying. If it is a food package that is not easily shifted when drying the inkjet code by blowing, it is only necessary to adjust the adjusting screw rod 212 by turning the turning handle 213 to make the pressing and fixing frame 210 move upward to a position higher than the hot air blower 207.

[0038] Embodiment 3, as Figure 4 As shown, a protective pad 216 is also arranged at the bottom of the pressing and fixing frame 210, and anti-slip lines are arranged at the bottom of the protective pad 216. Through the protective pad 216, it is possible to avoid the pressing and fixing frame 210 from causing pressing damage to the food package. Through the anti-slip lines, the friction between the pressing and fixing structure and the food package can be increased, thereby enhancing the pressing and fixing stability and limiting effect on the food package.

[0039] Embodiment 4, as Figure 4 As shown, a connecting plate 301 is arranged at the side end of the inkjet coder 108. A connecting bolt 302 for screwing and fixing with the mounting plate 107 is arranged on the connecting plate 301. Threaded connection holes adapted to the connecting bolt 302 are arranged on the mounting plate 107. The user can pass the connecting bolt 302 through the connecting plate 301 and screw it with the threaded connection hole to realize the flexible fixing of the inkjet coder 108 to the bottom of the mounting plate 107.

[0040] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
