Description

Technical Field

[0001] This utility model belongs to the field of molding device technology, specifically relating to a curved molding surface device that performs molding through rolling contact, and particularly to a convenient ink-filling double roller stamp. Background Technology

[0002] Roller stamps are a widely used stationery product. They use rollers to press the paper onto the paper to print the pattern on the rollers.

[0003] In order to meet the diversity of stamp patterns and colors, a multi-roller stamp is provided in related technologies. By setting each roller to different patterns and colors, the stamp can be combined on the paper to form a combination of different colors and patterns after printing.

[0004] The problem with the above technology is that, since the different rollers have different colors, each roller needs to be equipped with ink independently. The existing method of adding ink is usually to open the stamp cover and dip the roller into the ink box. However, this method is prone to causing color contamination when dealing with double roller stamps, especially when the two rollers are not the same color, thus affecting the pattern effect.

[0005] There is an urgent need to provide a convenient ink-filling dual-roller stamp to solve the technical problem of cross-contamination of inks when adding ink to dual-roller stamps in related technologies.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the figures, the thickness of parts may be exaggerated or reduced for the purpose of effectively depicting the technical content.

[0032] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] See Figure 2 , Figure 2 A convenient inking-type dual-roller stamp is shown, comprising: a housing 1, a cover 2, and a roller assembly 3; one end of the housing 1 has an opening, and the roller assembly 3 is disposed inside the housing 1 and extends partially from the opening; the cover 2 is movably disposed outside the end of the housing 1 with the opening and is configured to cover the roller assembly 3; and an inking assembly 4 is disposed inside the roller assembly 3 and is configured to add ink to the roller 32 in the roller assembly 3.

[0034] See Figure 3 In some embodiments, the roller assembly 3 is housed by the housing 1 and the cover 2. By setting the ink filling component 4 inside the roller assembly 3, each roller 32 is equipped with independent ink. When ink needs to be added to the roller 32, the ink in the ink storage chamber 40 is pushed by squeezing the ink filling rod 42 in the ink filling component 4, so that the ink flows to the roller 32 through the liquid filling hole 44. This realizes the internal addition of ink, improves the convenience of ink addition, and avoids the problem of color contamination caused by dipping ink in related technologies.

[0035] See Figure 4 In some embodiments, the roller assembly 3 includes a support frame 31 and a pair of parallel rollers 32 mounted in the support frame 31. Specifically, the sidewall of the roller 32 is provided with a connecting protrusion (not shown in the figure); the inner sidewall of the support frame 31 is provided with a connecting groove (not shown in the figure) corresponding to the position of the connecting protrusion; by inserting the connecting protrusion into the connecting groove, the roller 32 is connected to the support frame 31.

[0036] See Figure 5 In some embodiments, the roller 32 is made of a porous material, including but not limited to rubber or silicone. The ink reservoir of the ink filling assembly 4 is located inside the roller 32. The ink reservoir 41 is also provided with an ink injection rod 42 inside, and an ink injection plate 45 is provided at the tail end of the ink injection rod 42. The diameter of the ink injection plate 45 is adapted to the inner diameter of the ink reservoir 41, and there is a gap between the bottom of the ink injection plate 45 and the bottom of the ink reservoir 41 to form an ink storage cavity 40. The ink reservoir 41 has an injection hole 44 on the side wall corresponding to the ink storage cavity 40. When ink needs to be added, the ink reservoir 40 is squeezed by pushing the ink injection rod 42, so that the ink in the ink reservoir 40 is squeezed out, thereby realizing quick addition.

[0037] See Figure 6 In some embodiments, the support frame 31 has a through hole on its side wall for the end of the ink injection rod 42 to extend out. A spring 43 is arranged around the outer periphery of the ink injection rod 42. One end of the spring 43 abuts against the outer surface of the ink injection plate 45, and the other end abuts against the inner side wall of the top of the ink storage cylinder 41. When adding ink, the ink injection rod 42 is manually pushed to stretch the spring 43 and compress the ink storage cavity 40. After releasing, the spring 43 returns to its original position. By repeatedly pressing, the ink is squeezed and added.

[0038] In some embodiments, a first receiving recess is provided on the inner sidewall of the housing 1; a second receiving recess is provided on the inner sidewall of the cover 2; the first receiving recess and the second receiving recess are configured to form a receiving groove 5 that can cover the head end of the ink injection rod 42 after the housing 1 and the cover 2 are connected. The receiving groove 5 is provided to connect the housing 1 and the cover 2, that is, when the stamp is stored, the ink injection rod 42 is covered and cannot be squeezed, thereby avoiding accidental contact with the ink injection rod 42.

[0039] In some embodiments, a limiting protrusion 30 is also provided on the side wall of the support frame 31; a limiting groove 20 is provided on the inner side wall of the cover 2 corresponding to the position of the limiting protrusion 30, and the cover 2 can be snapped onto the outside of the support frame 31 through the cooperation of the limiting protrusion 30 and the limiting groove 20.

[0040] In some embodiments, a baffle 33 is also provided between the two rollers 32; the baffle 33 is mounted inside the support frame 31, and the bottom surface of the baffle 33 is higher than the bottom surface of the support frame 31, thereby preventing the rollers 32 from splashing ink onto the other roller 32 during the rotation printing process, so as to avoid color contamination.

[0041] In some embodiments, a plurality of supporting reinforcing ribs 10 are provided inside the housing 1; the bottom surface of the supporting reinforcing ribs 10 abuts against the top surface of the support frame 31, thereby clamping the support frame 31.

[0042] See Figure 1 and Figure 7 As another optional implementation of the ink filling component 4, the ink filling component 4 is configured to include an ink reservoir 41 and an ink-absorbing felt (not shown in the figure); the ink reservoir 41 is disposed inside the roller 32, and the ink-absorbing felt is disposed inside the ink reservoir 41; the ink reservoir 41 may have an ink injection hole, through which ink is dripped onto the ink-absorbing felt, and during the rolling of the roller 32, the ink is rotated and coated onto the inner side wall of the roller. The roller is selected to be a photosensitive material, so that the ink gradually penetrates to the outer surface of the roller.

[0043] In summary, this convenient ink-filling dual-roller 32 stamp accommodates the roller assembly 3 through the housing 1 and the cover 2. By setting the ink-filling component 4 inside the roller assembly 3, each roller 32 is equipped with independent ink. When ink needs to be added to the roller 32, the ink in the ink storage chamber 40 flows to the roller 32 through the injection hole 44 by squeezing the ink-filling rod 42 in the ink-filling component 4. This realizes internal ink addition, improves the convenience of ink addition, and avoids the problem of cross-contamination of colors when dipping ink in related technologies.
