Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a water dripping mechanism and a pad printing device. Background Art

[0002] The working principle of an oil cup type pad printing device is as follows: an oil cup filled with ink and a pad printing plate reciprocate relative to each other along a straight line. The ink in the oil cup fills into the pattern grooves on the surface of the pad printing plate during the movement; then, through the vertical downward movement of the pad printing rubber head, the ink filled in the pattern grooves is picked up, and then translated above a workpiece table on which a printing workpiece is pre-placed, and then moves downward to press the ink adhered to the surface of the pad printing rubber head onto the surface of the printing workpiece, completing the pad printing process.

[0003] The pad printing device disclosed in the Chinese utility model patent with the publication number CN217319740U includes a frame, a base, a pad printing plate, an oil cup, and a plurality of cylinders. The base is fixedly connected to the frame; the pad printing plate is slidably connected to the base, and pattern grooves are provided on the pad printing plate; the oil cup is arranged above the pad printing plate. As the pad printing plate reciprocates, the ink in the oil cup fills into the pattern grooves; a flange is provided at the bottom of the oil cup, and the flange protrudes radially from the outer surface of the oil cup; the plurality of cylinders are arranged at intervals around the axis of the oil cup. The first end of the cylinder is fixedly connected to the frame, and the second end presses the upper surface of the flange to press the oil cup against the surface of the pad printing plate; since the oil cup is pressed against the surface of the pad printing plate by the cylinder, the pressing force between the oil cup and the pad printing plate can be conveniently adjusted, and the flange is arranged at the bottom of the oil cup, so that the acting force of the cylinder on the oil cup directly acts on the bottom of the oil cup, so that the bottom of the oil cup can be more easily attached to the pad printing plate, and a reliable seal can be formed between the oil cup and the pad printing plate to prevent the oil cup from leaking oil.

[0004] However, when the device is actually used, since the viscosity of the ink directly affects the printing effect, when the working environment temperature is too high or it is placed for a long time, the ink is likely to become too thick, resulting in unsmooth printing or uneven patterns, affecting the printing effect.

Specific embodiments

[0027] Now, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, and therefore only showing the components related to the present utility model.

[0028] Such as Figure 1As shown in the figure, a water dripping mechanism includes: a support block 1, a water dripping bracket 2, and a three-axis moving component disposed between the support block 1 and the water dripping bracket 2; a water supply component for realizing water dripping is disposed on the water dripping bracket 2; the three-axis moving component includes: a fixed rod 3 fixed to the bottom of the support block 1, a connection block 31 fixed to one side of the water dripping bracket 2, and a connecting rod 32 disposed between the fixed rod 3 and the connection block 31; a segment connecting member 4 for segmenting the connecting rod 32 is disposed on the connecting rod 32; a first connecting member 5 for rotating the connecting rod 32 on the side surface of the fixed rod 3 is disposed at one end of the connecting rod 32, a second connecting member 6 for rotating the connection block 31 on the side surface of the connecting rod 32 is disposed at the other segment of the connecting rod 32, and a fastening connecting member 7 for mounting the connection block 31 on the second connecting member 6 is disposed on the connection block 31.

[0029] It should be noted that after the support block 1 is fixed at the working position, the support block 1 and the water dripping bracket 2 are connected through the three-axis moving component. At the same time, under the cooperation of the first connecting member 5, the second connecting member 6 and the fastening connecting member 7, the water dripping bracket 2 can be driven to adjust the position in the three-axis direction relative to the support block 1, so as to flexibly adjust the water dripping position, enabling it to adapt to ink tanks 10 of different sizes, ensuring that the water dripping position is located at the required water adding position. At the same time, under the cooperation of the water supply component, the effect of water dripping can be achieved at the bottom of the water dripping bracket 2, so that the viscosity of the ink can be adjusted by the way of water dripping.

[0030] As Figure 2 shown, in some embodiments, the water supply component includes: a water tank 21 clamped on the water dripping bracket 2, a micro water pump 22 fixed inside the water tank 21, and a drip water pipe 23 fixed to the output end of the micro water pump 22; one end of the drip water pipe 23 penetrates through the top of the water tank 21 and is located at the bottom of the water dripping bracket 2.

[0031] It should be noted that when the water dripping function needs to be realized, the micro water pump 22 in the water tank 21 is started, the water in the water tank 21 is pumped in from the input end, pressurized and then transported to the drip water pipe 23 through the output end. Since one end of the drip water pipe 23 penetrates through the top of the water tank 21 and is located at the bottom of the water dripping bracket 2, the water can be sent to the bottom of the water dripping bracket 2 to drip out, thus completing the water dripping effect.

[0032] In some embodiments, a water inlet 24 is fixed to the top of the water tank 21, and the inside of the water inlet 24 penetrates through to the inside of the water tank 21; through the setting of the water inlet 24, it is convenient to add water to the inside of the water tank 21 through the water inlet 24.

[0033] As Figure 3As shown, in some embodiments, the connecting rod 32 includes a first segmented rod 321 and a second segmented rod 322. The segmented connecting member 4 includes: a first connecting piece 41 fixed to one end of the first segmented rod 321, a second connecting piece 42 fixed to one end of the second segmented rod 322, and a card slot 43 formed on one side of the first connecting piece 41 and the second connecting piece 42; a C-shaped retaining ring 44 is clamped inside the card slot 43 located on the first connecting piece 41 and the second connecting piece 42; a threaded hole 45 is formed on the first connecting piece 41, a limiting hole 46 is formed on one side of the C-shaped retaining ring 44, a connecting screw 47 is arranged inside the limiting hole 46, the side surface of the connecting screw 47 is threadedly connected to the inside of the threaded hole 45, and one end of the connecting screw 47 abuts against one side of the second connecting piece 42.

The connecting screw 47 is passed through the limiting hole 46 on the C-shaped retaining ring 44 and screwed into the threaded hole 45 on the first connecting piece 41 until one end abuts against one side of the second connecting piece 42. Thus, the connection between the first segmented rod 321 and the second segmented rod 322 can be completed by relying on the tension of the C-shaped retaining ring 44 and the friction between the first connecting piece 41 and the second connecting piece 42. This can increase the length of the connecting rod 32, and at the same time, it is convenient for installation and disassembly, which helps to improve the convenience of maintenance and replacement.

[0035] In some embodiments, the first connecting member 5 includes: a first U-shaped block 51 sleeved on the side surface of the fixed rod 3 near the bottom end, a first convex rod 52 fixed to one end of the first segmented rod 321, and a first connecting hole 53 formed on the side surface of the first U-shaped block 51; the side surface of the first convex rod 52 is located inside the first connecting hole 53, and a first adjusting knob 54 is threadedly connected to one end of the first convex rod 52.

At the same time, the first segmented rod 321 can be rotated, and the first segmented rod 321 can rotate around the first connection hole 53 or the fixed rod 3 as the center. After rotation, the posture of the first segmented rod 321 after rotation can be maintained by friction. The operation is flexible and controllable, and it is convenient for installation and disassembly, which helps to improve the convenience of maintenance and replacement.

[0037] In some embodiments, the second connecting member 6 includes: a second U-shaped block 61 sleeved on the side of the second segmented rod 322 near one end, a second convex rod 62 provided on one side of the connecting block 31, and a second connection hole 63 opened on the side of the second U-shaped block 61; the side of the second convex rod 62 is located inside the second connection hole 63, and one end of the second convex rod 62 is threadedly connected with a second adjusting knob 64.

[0038] It should be noted that the diameter of the second connection hole 63 is the same as the diameter of one end of the second convex rod 62; the material of the second U-shaped block 61 is preferably plastic; during use, the middle part of the second U-shaped block 61 is sleeved on the side of the second segmented rod 322 near one end, the second convex rod 62 provided on one side of the connecting block 31 is passed through the inside of the second connection hole 63, and the second adjusting knob 64 is threadedly connected to one end of the second convex rod 62. After screwing in a certain length, one side of the second adjusting knob 64 will squeeze the second U-shaped block 61, so that it forms a clamping force on the side of the second segmented rod 322, and then the connecting block 31 and the drip bracket 2 can be installed on the side of the second segmented rod 322. At the same time, the drip bracket 2 can be rotated, and the drip bracket 2 can rotate around the second connection hole 63 or the second segmented rod 322 as the center. After rotation, the posture of the drip bracket 2 after rotation can be maintained by friction. The operation is flexible and controllable, and it is convenient for installation and disassembly, which helps to improve the convenience of maintenance and replacement.

[0039] In some embodiments, the fastening connecting member 7 includes: a fastening bolt 71 sleeved on the connecting block 31, a through hole 72 opened on the side of the second convex rod 62, and a fastening nut 73 threadedly connected to one end of the fastening bolt 71; the side of the fastening bolt 71 is located inside the through hole 72.

[0040] It should be noted that the diameter of the through hole 72 is the same as the diameter of one end of the fastening bolt 71; when in use, the fastening bolt 71 is passed through the through holes 72 on the connecting block 31 and the second convex rod 62 from one side of the connecting block 31 in sequence, and the fastening nut 73 is threadedly connected to one end of the fastening bolt 71, so that the side of the second convex rod 62 is tightly attached to one side of the connecting block 31, and then the connecting block 31 can be fastened and installed on the side of the second convex rod 62, and the drip bracket 2 can be rotated at the same time, so that the drip bracket 2 can be rotated with the through hole 72 as the center of the circle, and after rotation, the friction force can be used to maintain the posture of the drip bracket 2 after rotation, and the operation is flexible and controllable, and it is easy to install and disassemble, which helps to improve the convenience of maintenance and replacement.

[0041] The utility model provides a pad printing device, comprising a water dripping mechanism as described in any one of the above items.

[0042] like Figure 4 As shown, in some embodiments, the pad printing device includes: an equipment body 8, a pad printing workbench 9 fixed on the top of the equipment body 8, and an ink tank 10 opened on the top of the pad printing workbench 9; one side of the support block 1 is fixed to the side of the equipment body 8 close to the top, and the drip bracket 2 is located above the ink tank 10.

[0043] It should be noted that the support block 1 can be a drip bracket 2, which plays a supporting and fixing role on one side of the equipment body 8. After the position of the drip bracket 2 is adjusted to a suitable position above the ink tank 10, a proper amount of water can be dripped into the ink tank 10, which can dilute the ink to a certain extent and restore it to a suitable viscosity, making it easier to be dipped and transferred by the pad printing rubber head, which helps to ensure the smoothness and uniformity of printing. At the same time, the evaporation of the dripped water can take away some heat, thereby slowing down the drying speed of the ink in the ink tank 10, preventing the ink from drying out prematurely and affecting the printing quality and efficiency.

[0044] When the utility model is in use, the support block 1 is fixed on one side of the equipment body 8 to play a role of support and fixation. The first connecting piece 41 at one end of the first segmented rod 321 is attached to the second connecting piece 42 at one end of the second segmented rod 322, and both ends of the C-shaped snap ring 44 are respectively clamped in the clamping grooves 43 on one side of the first connecting piece 41 and the second connecting piece 42. The connecting screw 47 passes through the limiting hole 46 on the C-shaped snap ring 44 and is screwed into the threaded hole 45 on the first connecting piece 41 until one end abuts against one side of the second connecting piece 42. Thus, the connection between the first segmented rod 321 and the second segmented rod 322 can be completed by relying on the tension of the C-shaped snap ring 44 and the frictional force between the first connecting piece 41 and the second connecting piece 42. The middle part of the first U-shaped block 51 is sleeved on the side surface of the fixing rod 3 near the bottom end. The first convex rod 52 fixed at one end of the first segmented rod 321 passes through the inner side of the first connection hole 53, and the first adjusting knob 54 is threadedly connected to one end of the first convex rod 52. After screwing in a certain length, one side of the first adjusting knob 54 will squeeze the first U-shaped block 51 to form a clamping force on the side surface of the fixing rod 3. Thus, the first segmented rod 321 can be installed on the side surface of the fixing rod 3. The fastening bolt 71 passes through the through holes 72 on the connecting block 31 and the second convex rod 62 in sequence from one side of the connecting block 31, and the fastening nut 73 is threadedly connected to one end of the fastening bolt 71 to make the side surface of the second convex rod 62 closely adhere to one side of the connecting block 31. Thus, the connecting block 31 can be firmly installed on the side surface of the second convex rod 62. The middle part of the second U-shaped block 61 is sleeved on the side surface of the second segmented rod 322 near one end. The second convex rod 62 arranged on one side of the connecting block 31 passes through the inner side of the second connection hole 63, and the second adjusting knob 64 is threadedly connected to one end of the second convex rod 62. After screwing in a certain length, one side of the second adjusting knob 64 will squeeze the second U-shaped block 61 to form a clamping force on the side surface of the second segmented rod 322. Thus, the connecting block 31 and the water dripping support 2 can be installed on the side surface of the second segmented rod 322. At the same time, by using the three-axis moving assembly between the support block 1 and the water dripping support 2, the water dripping support 2 can be driven to perform position adjustment in three-axis directions relative to the support block 1, so that the position of water dripping can be flexibly adjusted. After adjusting the position of the water dripping support 2 to a suitable position above the ink tank 10, when the water dripping function needs to be realized, the micro water pump 22 in the water tank 21 is started, the water in the water tank 21 is pumped in from the input end, pressurized and then transported to the drip pipe 23 through the output end. Since one end of the drip pipe 23 penetrates through the top of the water tank 21 and is located at the bottom of the water dripping support 2, the water can be sent to drip out from the bottom of the water dripping support 2, so that the viscosity of the ink can be adjusted by the way of dripping water.
