It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0024] The rotary printing apparatus for filter housings provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0025] Example 1:

[0026] This application provides a rotary printing device for filter housings, including a machine body 1, a conveyor belt 2, a printing mechanism 3, a loading and unloading mechanism 4, a turntable 5, and several rotating seats 6. The printing mechanism 3 includes a transverse drive 31, a screen frame 32 with a screen, and a scraper 33. The transverse drive 31 is mounted on the top of the machine body 1 via the machine body 1 and is used to control the left and right movement of the screen frame 32. The scraper 33 is mounted on the machine body 1 via a lifting cylinder. There is a pair of scrapers 33, one of which is used to contact the screen and the other is not in contact with the screen.

[0027] like Figures 1 to 2As shown, due to the above structure, the shells to be printed are transported in batches to the designated station by the conveyor belt 2. The loading and unloading mechanism 4 (using pneumatic grippers or vacuum suction cups) accurately grabs the shells and places them stably on the rotating seat 6 of the turntable 5. The rotating seat 6 simultaneously positions and clamps the shells to prevent displacement during printing. The turntable 5 rotates at a uniform speed, driving the shells to flow to the bottom of the printing mechanism 3. The horizontal movement driver 31 adjusts the left and right positions of the screen frame 32 according to the shell specifications to ensure accurate alignment. The lifting cylinder drives one of the scrapers 33 to move down to contact the screen, and together with the screen frame 32, completes the printing of information such as the model and batch number on the surface of the shell. The other scraper 33 assists in scraping back the excess ink on the screen surface. After printing, the turntable 5 sends the shells to the unloading station. The loading and unloading mechanism 4 operates again to remove the printed shells from the rotating seat 6 and smoothly transfer them to the subsequent drying line, realizing the integrated operation of "loading-positioning-printing-unloading".

[0028] Example 2:

[0029] In this embodiment, in addition to the structural features of the aforementioned embodiments, the transverse drive 31 includes a fixed frame 311, a support frame 312, and a power element 313. The fixed frame 311 is fixed to the top of the body 1, the support frame 312 is movably mounted in the fixed frame 311 through a sliding pair, the power element 313 is used to drive the support frame 312 to reciprocate transversely, and the wire mesh frame 32 is detachably mounted in the support frame 312.

[0030] In this embodiment of the application, the support frame 312 includes a transverse sliding plate 3122 opening and closing adjustment mechanism 7 and a pair of connecting frames 3121. The pair of connecting frames 3121 are movably mounted on the support frame 312. The opening and closing adjustment mechanism 7 is mounted on the support frame 312 and is used to control the opening and closing of the pair of connecting frames 3121. Both ends of the wire mesh frame 32 are detachably connected to the corresponding connecting frame 3121 through quick-release elements 8.

[0031] like Figures 1 to 2As shown, due to the above structure, the fixed frame 311 provides a stable installation base for the bearing frame 312, which is suitable for long-term continuous operation. The power element 313 (which uses a transmission belt and a pair of pulleys, with the pair of pulleys rotatably installed at both ends of the bottom of the fixed frame 311, one of which is driven by a motor, and the two ends of the transmission belt are respectively sleeved on the pair of pulleys, with the middle fixed to the bearing frame 312) drives the transverse sliding plate 3122 to move smoothly back and forth within the fixed frame 311 along the sliding pair (including a pair of sliding rods fixed on the fixed frame 311 and a pair of sliding holes provided on the transverse sliding plate 3122, with the sliding rods and sliding holes slidingly engaging with each other), ensuring the moving accuracy of the screen frame 32 and improving the printing alignment accuracy. When it is necessary to switch between different specifications of screen frames 32, the spacing of the pair of connecting frames 3121 is first adjusted by the opening and closing adjustment mechanism 7 to match the width of the screen frame 32 to be installed. Then, the old screen frame 32 is disassembled by the quick-release element 8, and the two ends of the new screen frame 32 are connected and fixed to the connecting frame 3121.

[0032] Example 3:

[0033] In this embodiment, in addition to the structural features of the aforementioned embodiments, the quick-release element 8 includes a mounting frame 81 and a mounting member 82. The mounting frame 81 is disposed on the connecting frame 3121, and the mounting member 82 is disposed on the mounting frame 81 and has a connecting frame 83. The end of the wire mesh frame 32 is inserted into the connecting frame 83 and fixed by a fastener 84.

[0034] In this embodiment of the application, a plurality of adjusting devices 9 are also included, for adjusting the mounting frame 81 to be mounted on the connecting frame 3121 and the mounting component 82 to be adjusted to be mounted in the mounting frame 81, wherein the connecting frame 3121 and the mounting frame 81 are arranged perpendicular to each other.

[0035] like Figures 1 to 2 As shown, due to the above structure, when installing the screen frame 32, first insert both ends of the screen frame 32 into the connecting frame 83 of the mounting component 82. After adjusting the position, use the fasteners 84 to press and fix the screen frame 32 to prevent it from shifting due to vibration during equipment operation. When it is necessary to fine-tune the position of the screen frame 32, adjust the vertical position of the mounting frame 81 on the connecting frame 3121 and the front-back position of the mounting component 82 in the mounting frame 81 using the adjusting device 9. With the connecting frame 3121 and the mounting frame 81 set perpendicular to each other, the screen frame 32 can be accurately aligned in multiple dimensions, ensuring that the screen and the printing surface of the shell are completely adhered, effectively improving the product printing qualification rate and adapting to the production needs of multiple varieties in the workshop. When disassembling the screen frame 32, loosen the fasteners 84 to remove the screen frame 32 from the connecting frame 83. The operation is simple and efficient.

[0036] Example 4:

[0037] In this embodiment, in addition to the structural features of the aforementioned embodiments, the fastener 84 is a bolt, which passes through the corresponding screw hole on the top surface of the outer end of the mounting part 82, and the lower end of the bolt is used to extend into the connecting frame 83 to press the wire mesh frame 32.

[0038] In this embodiment of the application, the inner end of the connecting frame 83 is closed, and each mounting piece 82 is provided with a pair of fasteners 84 on its top.

[0039] like Figures 1 to 2 As shown, due to the above structure, when installing the wire mesh frame 32, the end of the wire mesh frame 32 should first be aligned with the connecting frame 83 of the mounting component 82 and smoothly inserted into the inner end of the connecting frame 83. Then, use a wrench or other common tools to tighten the pair of bolts on the top of the mounting component 82 so that the lower end of the bolts extends into the connecting frame 83 to press the wire mesh frame 32, ensuring that the wire mesh frame 32 is firmly fixed and the force is even. When disassembling the wire mesh frame 32, the operation steps are reversed. First, use a tool to loosen the pair of bolts, and then pull the wire mesh frame 32 out of the connecting frame 83.

[0040] Example 5:

[0041] In this embodiment, in addition to the structural features of the aforementioned embodiments, the adjusting device 9 includes an adjusting screw 91 and an adjusting screw hole. The adjusting screw 91 is rotatably mounted in the connecting frame 3121 or the mounting frame 81, and the adjusting screw hole is opened in the mounting frame 81 or the mounting component 82 and is in transmission cooperation with the adjusting screw 91.

[0042] In this embodiment of the application, the opening and closing adjustment mechanism 7 includes a bidirectional screw 71, a plurality of slide grooves 72 and a pair of sliders 73. Each slide groove 72 is spaced apart on the top of the transverse sliding plate 3122, and the pair of sliders 73 are respectively slidably installed in the slide grooves 72 at both ends. The bidirectional screw 71 and the pair of sliders 73 are driven by screw holes.

[0043] In this embodiment of the application, a knob is fixedly provided at the outer end of the adjusting screw 91 or the bidirectional screw 71.

[0044] like Figures 1 to 2 As shown, due to the above structure, when adjusting the position of the wire mesh frame 32, the operator only needs to turn the knob at the outer end of the adjusting screw 91 by hand. Through the transmission cooperation between the adjusting screw 91 and the adjusting screw hole, the relative movement between the mounting frame 81 and the connecting frame 3121, and between the mounting part 82 and the mounting frame 81 can be driven, so as to achieve multi-dimensional precise micro-adjustment of the wire mesh frame 32. The whole process does not require special tools, the operation is simple and easy to understand, and it is suitable for the operating habits of front-line operators.

[0045] When adjusting the spacing of the connecting frame 3121 to adapt to different widths of wire mesh frames 32, rotating the knob at the outer end of the bidirectional screw 71 will drive a pair of sliders 73 to slide synchronously towards or away from each other along the slide groove 72, thereby driving the connecting frame 3121 to open and close synchronously. The adjustment is precise and the action is synchronous, which can quickly complete the specification switching. The knob design not only reduces the difficulty of operation, but also eliminates the need for power tools, thereby reducing equipment energy consumption and avoiding the risk of power tool failure in the dusty environment of the workshop. This effectively improves equipment stability and ensures continuous and efficient production.
