Description

Technical Field

[0001] The utility model relates to the technical field of pad printing machine scraper structures, in particular to a pad printing machine rubber head follower scraper structure. Background Art

[0002] Pad printers are a type of printing equipment that can precisely transfer a design onto a toy's surface. They produce exquisite, detailed prints, making them suitable for small areas, concave and convex surfaces, and other areas where other printing methods struggle. Therefore, pad printers hold an irreplaceable position in the toy manufacturing industry.

[0003] During operation, the pad printer's pad needs to dip into the ink pan to collect ink before transferring it to the toy. However, in existing pad printers, the scraper is fixed to the machine, making it impossible to adjust the ink thickness in real time. This can easily cause uneven ink collection by the pad, resulting in poor pad printing quality. Utility Model Content

[0004] Based on this, the utility model provides a pad printing machine rubber head follower scraper structure with simple structure and easy use. The scraper and the oil roller are connected to the carrier through a scraper lifting cylinder. The height position of the scraper and the oil roller can be adjusted in real time, and the ink thickness in the dipping area can be accurately controlled, thereby improving the uniformity of the ink dipped by the rubber head and ensuring the pad printing quality.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0033] See also Figures 1 to 6, which is a pad printing machine rubber head follower scraper structure of an embodiment of the present invention, includes a machine body 10, a pad head assembly 20 movably installed inside the top of the machine body 10, a scraper assembly 30 matched and connected to one side of the pad head assembly 20, and an oil pan 40 located below the scraper assembly 30.

[0034] The body 10 includes a housing 11 and transverse guide rods 12 installed on opposite sides of the top of the housing 11 ; the transverse guide rods 12 are used to match and connect the rubber head assembly 20 .

[0035] The glue head assembly 20 includes a carrier 21 movably mounted inside the top of the casing 11, a first limit pin 22 mounted on the front of the carrier 21, a second limit pin 23 mounted on the back of the carrier 21, a transverse cylinder 24 connected to the back of the carrier 21, a glue head support 25 mounted below the front of the carrier 21 for lifting, glue heads 26 mounted at opposite ends of the bottom surface of the glue head support 25, and a glue head lifting cylinder 27 mounted above the front of the carrier 21; the glue head lifting cylinder 27 is connected to the glue head support 25 to drive the glue head 26 to perform lifting movements.

[0036] In this embodiment, the opposite sides of the carrier 21 are respectively connected to the transverse guide rod 12 by sliding sleeves; the cylinder body of the transverse cylinder 24 is fixedly connected to the casing 11, and the piston rod of the transverse cylinder 24 is connected to the carrier 21. The transverse cylinder 24 is used to drive the carrier 21 to slide along the transverse guide rod 12.

[0037] In this embodiment, the first limiting pin 22 and the second limiting pin 23 are both used to abut against the inner wall of the housing 11 to limit the movement range of the entire rubber head assembly 20 .

[0038] In this embodiment, first linear bearings 211 are mounted on opposite sides of the front surface of the carrier 21, with the axis of the first linear bearings 211 aligned with the vertical direction. First lifting guide rods 250 are mounted on opposite ends of the top surface of the rubber head support 25. The first lifting guide rods 250 mate with the first linear bearings 211 to achieve a lifting connection between the rubber head support 25 and the carrier 21.

[0039] Furthermore, second linear bearings 212 are respectively installed on two opposite sides of the back of the carrier 21 . The axis direction of the second linear bearing 212 is consistent with the vertical direction. The second linear bearing 212 is used to match and connect the scraper assembly 30 .

[0040] The scraper assembly 30 includes a scraper support 31 installed for lifting at the bottom of the back of the carrier 21, scrapers 32 installed on opposite sides of the bottom surface of the scraper support 31, oil rollers 33 installed on the back of each scraper 32, and a scraper lifting cylinder 34 installed above the back of the carrier 21; the scraper lifting cylinder 34 is connected to the scraper support 31 to drive the scraper 32 and the oil roller 33 to move up and down, thereby adjusting the height position of the scraper 32 and the oil roller 33 inside the oil pan 40, and adjusting the ink thickness in real time.

[0041] In this embodiment, second lifting guide rods 310 are respectively installed on opposite sides of the top surface of the scraper support 31 . The second lifting guide rods 310 are matched and connected with the second linear bearing 212 to realize the lifting connection between the scraper support 31 and the support 21 .

[0042] like Figure 4 As shown, the interior of the oil pan 40 is provided with a dipping area 41 and a storage area 42. A protrusion 43 is provided on the oil pan 40 corresponding to the connection between the dipping area 41 and the storage area 42. The top surface of the protrusion 43 is higher than the dipping area 41 and the storage area 42, effectively separating the dipping area 41 from the storage area 42.

[0043] Furthermore, the depth of the dipping area 41 is smaller than the depth of the storage area 42, which can better control the flow and distribution of the ink.

[0044] In actual use, the scraper lift cylinder 34 drives the scraper 32 and the oil roller 33 into the storage area 42. By controlling the height of the scraper 32 and the oil roller 33 within the storage area 42, the ink is pushed over the raised portion 43 and into the pick-up area 41, thereby adjusting the ink thickness in the pick-up area 41 and facilitating subsequent pick-up by the pad 26. It is understood that if the ink thickness in the pick-up area 41 is too thick, the scraper 32 can be used to push the ink in the pick-up area 41 back into the storage area 42, increasing operational flexibility and convenience to meet the needs of pad printing on different product surfaces.

[0045] The above-mentioned pad printing machine's rubber head follower scraper structure has a simple structure and is easy to use. The scraper 32 and the oil roller 33 are connected to the carrier 21 through the scraper lifting cylinder 34. The height position of the scraper 32 and the oil roller 33 can be adjusted in real time, and the ink thickness in the dipping area 41 can be accurately controlled, thereby improving the uniformity of the ink dipped by the rubber head 26 and ensuring the pad printing quality.

[0046] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
