Description

Technical Field

[0001] This utility model relates to the field of bag printing technology, and in particular to a bag printing inkjet quick-drying and static electricity removal device. Background Technology

[0002] In the packaging and printing industries, inkjet printing of film bags is widely used, and its production efficiency and print quality directly affect the smooth progress of subsequent processes. In traditional inkjet printing, after the bags are printed at the inkjet nozzle, the ink is not completely dry. If they are directly sent to the collection, stacking, or transfer stages, the pattern is easily blurred or smudged due to surface contact, affecting the product's appearance and label recognition. In addition, because the film material is prone to generating static electricity and accumulating locally during transportation and separation, the printed bags often stick together, shift, or adhere to the equipment surface due to static attraction, causing difficulties in handling, poor transportation, and even an increased defect rate.

[0003] Currently, common processing methods mainly rely on natural air drying or heat drying. Natural air drying requires a large space and takes a long time, making it unsuitable for continuous production. While heat drying can accelerate drying, it suffers from high energy consumption, is unsuitable for heat-sensitive materials, and cannot effectively eliminate static electricity. Some solutions attempt to install static eliminators after printing, but these are often separated from the drying process, increasing equipment complexity and layout difficulties.

[0004] Therefore, it is necessary to provide a bagged inkjet quick-drying and static-eliminating device to overcome the above-mentioned defects. Utility Model Content

[0005] The purpose of this invention is to provide a bagged inkjet fast-drying and static elimination device, which aims to solve the problem of how to simultaneously achieve rapid drying and static elimination after inkjet printing, thereby improving production continuity and operational efficiency while ensuring print quality.

[0011] In a preferred embodiment, the base is provided with a pair of parallel and spaced mounting plates; the conveyor belt includes two rotating shafts and belts sleeved on the two rotating shafts; the two ends of each rotating shaft are rotatably connected to the two mounting plates; the two rotating shafts are located at the two ends of the mounting plates.

[0012] In a preferred embodiment, a baffle is provided vertically on one side of the two mounting plates that are close to each other, and the vertical projection of the baffle relative to the base is outside or partially overlaps with the vertical projection of the belt line relative to the base.

[0013] In a preferred embodiment, the fixing bracket includes a vertical mounting plate fixed to the base, a horizontal connecting rod vertically fixed to the top side of the vertical mounting plate, and a fixing block fixed to the side of the horizontal connecting rod away from the vertical mounting plate; the spray nozzle is fixed to the fixing block.

Detailed Implementation

[0020] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described in this specification are merely for explaining the present utility model and are not intended to limit the present utility model.

[0021] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0022] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0023] In an embodiment of this utility model, a bag-type inkjet quick-drying and static electricity removal device 100 is provided, which is used to blow air onto the film bag after the label or text pattern has been printed, so that the ink on the surface of the bag is dried quickly and the static electricity accumulated on the surface of the bag is removed, ensuring the normal printing and transportation of the bag.

[0024] like Figures 1-4 As shown, the bagged inkjet quick-drying and static elimination device 100 includes: a base 10, a fixed bracket 20, and an air blowing assembly 30.

[0025] The base 10 is equipped with a conveyor belt 11, which is used to transport the bags to be printed and to send out the printed bags.

[0026] Specifically, the base 10 is provided with a pair of parallel and spaced mounting plates 12. The conveyor belt 11 includes a drive motor, two rotating shafts, and belts sleeved on the two rotating shafts. The two ends of each rotating shaft are rotatably connected to the two mounting plates 12. The two rotating shafts are located at the two ends of the mounting plates 12. The drive motor drives one of the rotating shafts to rotate, thereby moving the bag on the belt towards the air blowing assembly 30.

[0027] Furthermore, a baffle 13 is vertically provided on one side of the two mounting plates 12 that are close to each other. The vertical projection of the baffle 13 relative to the base 10 is outside or partially overlaps with the vertical projection of the belt line relative to the base 10, thereby shielding the structures on the left and right sides of the belt line.

[0028] The fixed bracket 20 is equipped with a printhead 40 located above the conveyor belt 11. The printhead 40 is used for inkjet printing on the bags to be printed placed on the conveyor belt 11. It should be noted that the printhead 40 (and the printing equipment components connected to it) performs inkjet printing on the surface of a thin film. Its core is to precisely spray tiny ink droplets onto the material surface in a non-contact manner. Existing structures such as piezoelectric printheads (which utilize the inverse piezoelectric effect of piezoelectric ceramic materials. When a voltage is applied, the ceramic sheet deforms, squeezing the pressure chamber and expelling the ink droplets from the nozzle), thermally aerated printheads (which instantly heat the ink (about 300°C) through tiny thin-film resistors, generating bubbles that expand and eject ink droplets), and electrohydrodynamic printheads (which directly generate tension on the meniscus of the ink by applying a strong electric field at the nozzle, forming an extremely fine jet) can be used. This utility model does not limit these structures.

[0029] The fixed bracket 20 includes a vertical mounting plate 21 fixed to the base 10, a horizontal connecting rod 22 vertically fixed to the top side of the vertical mounting plate 21, and a fixing block 23 fixed to the side of the horizontal connecting rod 22 away from the vertical mounting plate 21. The spray nozzle 40 is fixed to the fixing block 23. Further, the fixing block 23 is provided with a mounting groove 24, and a locking adjustment component 25 is provided at the opening of the mounting groove 24. The locking adjustment component 25 is used to adjust the force with which the mounting groove 24 clamps the spray nozzle 40, thereby adjusting the height of the spray nozzle 40 relative to the base 10; when the height of the spray nozzle 40 needs to be adjusted, the locking adjustment component 25 can be loosened.

[0030] The air blowing assembly 30 is fixed to the base 10 and located at the end of the conveyor belt 11 for blowing air onto the inkjet-printed bag.

[0031] Specifically, the air blowing assembly 30 includes an air jet tube 31 and a pair of mounting blocks 32 respectively connected to both sides of the air jet tube 31. The mounting blocks 32 are fixed to the base 10. The side of the air jet tube 31 has several air outlets 301 facing the bag. The air jet tube 31 has a built-in fan or is connected to an external air blowing device (e.g., a blower) to blow air outward through the air outlets 301, thereby quickly drying the inkjet ink on the surface of the bag. It should be noted that the blowing rate of the air jet tube 31 does not need to be very high, and the air is blown vertically towards the bag from top to bottom or bottom to top, thereby avoiding blowing the bag away.

[0032] Furthermore, the number of jet nozzles 31 is two, arranged parallel to each other vertically. The air outlets 301 of the two jet nozzles 31 face the upper and lower sides of the bag respectively, which can effectively prevent the bag from being blown off-center by one side. Each mounting block 32 includes a pair of elastic arms 321, which together form a slot 322. The jet tube 31 opens the slot 322 and is held within it, meaning the opening of the slot 322 is slightly smaller than the diameter of the jet tube 31, preventing the jet tube 31 from detaching from the slot 322. Furthermore, each elastic arm 321 has a curved or inclined guide surface 323 on the side near the opening of the slot 322, facilitating the insertion of the jet tube 31 into the slot 322.

[0033] In some embodiments, a heating element (not shown) is provided inside the jet nozzle 31. The heating element is used to heat the air so that the air outlet 301 can blow out warm air, which accelerates the drying efficiency of the inkjet and does not damage the bag.

[0034] Furthermore, the principle behind the air blowing assembly 30 for removing static electricity from the surface of the film bag is as follows: high-speed airflow induces air ionization, and the particles generated by ionization, carrying opposite charges, are transported to the bag surface, thereby neutralizing its static electricity. Specifically, the airflow (especially when ejected from a nozzle with a sharp outlet, where the outlet 301 can be designed in this shape, though the illustration does not represent the actual shape) causes intense turbulence and friction in the air. This friction process ionizes air molecules, generating a small number of positive and negative ions (more professional static eliminators use high-voltage corona discharge to actively generate a large number of ions, but even pure air blowing can generate trace amounts of ions through the above effect). The transported positive ions combine with negatively charged areas on the bag surface, while the negative ions combine with positively charged areas, thus canceling out the positive and negative charges on the surface and achieving the purpose of neutralizing (eliminating) static electricity.

[0035] In summary, the inkjet quick-drying and static electricity removal device 100 for bagging provided by this utility model, through the reasonable arrangement of the air blowing component 30, performs directional air blowing on the bag immediately after inkjet printing, using airflow to accelerate ink evaporation to achieve quick drying, and at the same time, effectively dissipates static electricity on the surface of the bag by means of airflow, thereby solving the drying and static adsorption problems in one go within a compact process flow, improving production efficiency and product qualification rate.

[0036] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
