Description

Technical Field

[0001] This utility model belongs to the field of pad printing equipment technology, specifically relating to a pad printing device for pipe fittings. Background Technology

[0002] There are many types of medical tracheas. To make it easier to distinguish the types of tracheas, they are marked with labels to prevent medical staff from accidentally connecting the tubes in an emergency, which could lead to incorrect gas input or cross-infection.

[0003] To improve production efficiency, current labeling of air tubes is achieved using pad printing equipment, such as the tube product labeling printing equipment authorized under announcement number CN220923566U. To improve ink adhesion and printing quality, dust needs to be removed from the air tube surface before pad printing; currently, this step is done manually, which is inefficient.

Detailed Implementation

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] A pipe fitting pad printing device, see Figures 1-4 It includes a main body 100 and a worktable 200, a dust removal mechanism 300, a pad printing mechanism 400 and a drying mechanism 500 disposed on the main body 100.

[0021] The workbench 200 is equipped with a rotatable turntable 210, which has multiple clamps 220 for fixing pipe fittings. In this embodiment, four clamps 220 are provided, and they are evenly spaced along the circumference of the turntable 210. The four clamps 220 are used for feeding, dust removal, printing, and drying, respectively. Correspondingly, in the rotation direction of the turntable 210, the dust removal mechanism 300, the pad printing mechanism 400, and the drying mechanism 500 are arranged sequentially, as shown in the figure. The dust removal mechanism 300, the pad printing mechanism 400, and the drying mechanism 500 are located on the left, rear, and right sides of the workbench 200, respectively. With this layout, the four processes of feeding, dust removal, printing, and drying can be performed simultaneously and cyclically, ensuring processing efficiency.

[0022] The fixture 220 is provided with a fixing groove 221 for fixing the air tube. The shape and size of the fixing groove 221 are adapted to the tube to be printed, thereby limiting the tube within the fixing groove 221. The bottom of the fixing groove 221 is provided with an adsorption hole 222 to fix the tube. The depth of the fixing groove 221 is less than the thickness of the tube, thereby avoiding the groove depth from affecting the printing.

[0023] The pad printing mechanism 400 includes a gravure plate, a printing head, etc. The printing head dips the ink from the gravure plate onto its surface, and then moves towards the fixture 220 to print the pattern on the printing head onto the surface of the pipe fitting. This pad printing mechanism 400 uses an existing mechanism, which will not be described in detail here.

[0024] The dust removal mechanism includes a support 310, a detection element 320, and a spray gun 330. The support 310 is fixed to the main body 100. The detection element 320 is mounted on the support 310 and is used to detect whether a pipe is placed on the fixture 220. The spray gun 330 is mounted on the support 310, with its outlet facing the fixing groove 221. It sprays gas when the detection element 320 detects a pipe on the fixture 220. When a newly loaded pipe rotates to the dust removal station, the spray gun 330 is aligned with the fixing groove 221 of the fixture 220. After the detection element 320 detects the pipe on the fixture 220, the spray gun 330 sprays air to blow away dust from the pipe surface, making the pipe surface clean and improving ink adhesion and printing quality. Automatic dust removal by the dust removal mechanism 300 is more efficient than traditional manual dust removal. The detection element 320 is set to detect whether a pipe is placed on the fixture 220. When the detection element 320 detects that a pipe is placed on the fixture 220, the spray gun 330 sprays gas to remove dust, so as to avoid the phenomenon of dry spraying and reduce energy consumption.

[0025] The detection element 320 can be a distance sensor or a vision sensor, etc.

[0026] In this embodiment, the spray gun 330 is rotatably connected to the bracket 310, which can adjust the spray angle of the spray gun 330 and ensure that the airflow sprayed by the spray gun 330 can be accurately sprayed onto the pipe to ensure the dust removal effect.

[0027] Specifically, the bracket 310 includes a column 311 and a first connecting member 312. The column 311 is mounted on the main body 100, and the first connecting member 312 is disposed on the column 311. The first connecting member 312 has a pivot hole 3121 and an arc-shaped hole 3122, with the center of the arc-shaped hole 3122 located at the pivot hole 3121. Preferably, the two are concentric. The spray gun 330 has a connecting piece 331, which has a first connecting hole 3311 and a second connecting hole 3312. The first connecting hole 3311 and the second connecting hole 3312 are respectively opposite to the pivot hole 3121 and the arc-shaped hole 3122. Fasteners are provided between the first connecting hole 3311 and the pivot hole 3121, and between the second connecting hole 3312 and the arc-shaped hole 3122. The fasteners pass through the corresponding openings to fix the spray gun 330 to the first connecting member 312. During actual assembly, the spray gun 330 can rotate around the pivot hole 3121 (first connecting hole 3311) along the arc-shaped hole 3122 to adjust its spray angle.

[0028] The fastener is preferably a bolt, which is tightened by a bolt and nut (with a built-in threaded hole).

[0029] In this embodiment, the bracket 310 further includes a second connector 313, which is slidably mounted on the column 311 so that it can move toward or away from the clamp 220 to adjust its position. The detection element 320 is located on the side of the second connector 313 that is closer to the clamp 220.

[0030] Specifically, the column 311 is provided with a connecting strip 314, the top of which has a threaded hole 3141. The second connecting member 313 has a strip-shaped hole 3131. A bolt passes through the strip-shaped hole 3131 and connects to the threaded hole to fasten the second connecting member 313. The movement of the second connecting member 313 is achieved through the cooperation of the threaded hole and the strip-shaped hole 3131, thereby adjusting the position of the detection element 320 and ensuring the detection effect.

[0031] The second connector 313 abuts against the first connector 312, thus ensuring high stability after assembly.

[0032] The fixed groove 221 is arranged radially along the turntable 210, and the spray gun 330 is arranged in the same direction as the fixed groove 221. In this way, after the turntable 210 stops rotating, the airflow blown by the spray gun 330 can cover the entire pipe and ensure the dust removal effect.

[0033] The drying mechanism 500 includes a housing, a heating element, and a fan. The heating element is located inside the housing, and the fan is mounted above the heating element. An air outlet is located at the bottom of the housing. After printing, the fixture 220 is moved to the drying position by rotation, and the fan rotates to blow hot air onto the fixture 220, accelerating the curing of the pattern.

[0034] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
