Description

TECHNICAL FIELD

[0001] The present application relates to the field of hand tools, in particular to the field of pattern stamping technology, and in particular to a stamping machine. BACKGROUND

[0002] A stamping machine is a device that uses the extrusion of two plates to transfer ink through a graphic portion to a stamping carrier. Through the stamping machine, consumers can print their favorite patterns on paper, clothes or other stamping carriers. For example, Chinese patent application No. CN201811045056.3 (publication No. CN109353135A) discloses a stamping machine, which comprises a body (1), the body (1) comprising a bottom plate (2) for placing a carrier and a stamp, a pressing plate (3) for pressing the carrier and the stamp in cooperation with the bottom plate (2), a magnetic attraction structure (4) for generating mutual attractive force between the pressing plate (3) and the bottom plate (2), and a working space (21) for placing the carrier and the stamp on the upper surface of the bottom plate (2).

[0003] Compared with ordinary pure manual stamping, a stamping machine can obtain more rich stamping patterns and is more convenient to use. However, the existing stamping machines generally have the following problems: (1) the positioning between the two plates is not stable, and the stamp and the stamping carrier are prone to displacement during stamping, which causes the stamping pattern to be dislocated or blurred, affecting the stamping quality; (2) the stamp is unevenly stressed during stamping, causing the stamping pattern to have different color depths, which needs to be reprinted, affecting the stamping effect and user experience; (3) if the pattern is not complete during the first stamping, it is difficult to ensure that the two stamping patterns coincide when re-stamping because the last positioning cannot be accurately repeated. SUMMARY

[0004] The first technical problem to be solved by the present application is to provide a stamping machine that is simple and accurate in positioning the stamp and the stamping carrier.

[0005] The second technical problem to be solved by the present application is to provide a stamping machine that is simple and accurate in positioning the stamp and the stamping carrier and can realize straight-line repeated stamping.

[0006] The technical scheme adopted by the present application to solve at least one of the above technical problems is: a seal stamping machine, comprising oppositely arranged first and second plate bodies capable of pressing a seal and a stamping carrier located between the first and second plate bodies, characterized in that the second plate body is provided with a positioning column facing the first plate body, the first plate body is provided with a positioning hole for the positioning column to insert, and an elastic reset structure is arranged between the second and first plate bodies, and the elastic reset structure makes the second and first plate bodies have a tendency to move away from each other in a pressed state.

[0007] Further, the elastic reset structure is arranged on the first plate body and is at least two, so that the first and second plate bodies can maintain a predetermined distance in a free state, the positioning hole is arranged at one end of the first plate body and is adjacent to one of the elastic reset structures, and the other elastic reset structure is arranged at the other end of the first plate body. On the one hand, the relative positioning between the second and first plate bodies can be achieved by the cooperation of the positioning column and the positioning hole, and on the other hand, the elastic reset structures can be uniformly arranged between the second and first plate bodies, so that the positioning of the stamping carrier can be better achieved, and the stress on the seal can be more uniform during pressing.

[0008] Further, at least one side edge of the second plate body extends in a straight line direction, the positioning columns are arranged along the side edge of the second plate body, and the positioning holes of the first plate body correspond to the positioning columns one by one, or the number of the positioning holes on the first plate body is less than the positioning columns, and the positioning holes can be inserted by any corresponding number of positioning columns.

[0009] Further, the first plate body can move back and forth along the length direction of the side edge of the second plate body, and during the movement, the corresponding positioning columns on the second plate body can be inserted into the corresponding positioning holes of the first plate body, and the corresponding positions of the lower surface of the first plate body and the upper surface of the second plate body are always opposite. In this way, straight-line stamping on the stamping carrier can be achieved as the first plate body moves along the second plate body, that is, the text or pattern on the seal is repeatedly stamped on the stamping carrier along the arrangement direction of the positioning columns as the first plate body moves.

[0010] Further, the first plate body is located above the second plate body, the elastic reset structure includes a first mounting groove opened on the lower surface of the first plate body, a first reset spring mounted in the first mounting groove, and a pressing cap, the upper end of the pressing cap is inserted into the first mounting groove and can move up and down along the depth direction of the first mounting groove, and the first reset spring is limited between the inner bottom surface of the first mounting groove and the inner bottom surface of the pressing cap. In this way, on the one hand, the stable installation of the first reset spring and the column can be achieved, and on the other hand, the first reset spring can fully provide the pressing elastic force during pressing.

[0011] Furthermore, a first guide sleeve is embedded in the first mounting groove. The inner circumferential surface of the first guide sleeve has vertically extending first guide grooves spaced at intervals along the circumference. The outer surface of the opening end of the pressing cap has first guide protrusions spaced at intervals along the circumference, each corresponding to one of the first guide grooves. Each first guide protrusion is inserted into its corresponding first guide groove and can move up and down along that groove. The cooperation between the first guide protrusions on the pressing cap and the first guide grooves on the first guide sleeve allows the pressing cap to move up and down more smoothly, thereby ensuring more even force distribution on the stamp.

[0012] Furthermore, an anti-slip pad is provided at the free end of the pressing cap. This anti-slip pad prevents the first plate from moving laterally on the stamping carrier, improving the stability of the stamping positioning. Furthermore, the bearing surface of the second plate is provided with an alignment angle that matches at least one corner of the stamping carrier and allows for alignment of that corner. This enables angular positioning of the stamping carrier, preventing movement of the stamping carrier during the stamping process and ensuring the accuracy of the stamping position, especially when stamping the corners of the stamping carrier.

[0013] There are several ways to implement the aforementioned alignment angle. One preferred method is that the alignment angle is a groove formed by the downward-facing concavity of the bearing surface of the second plate. In this way, the alignment angle not only aligns the stamping carrier but also positions it, thus better preventing displacement of the stamping carrier during the stamping process.

[0014] Another preferred implementation of the aforementioned alignment angle is that the alignment angle is a line set on the bearing surface of the second plate.

[0015] Furthermore, the lines are either engraved lines recessed on the bearing surface of the second plate or printed lines printed on the bearing surface of the second plate.

[0016] Another preferred implementation of the aforementioned alignment angle is that the alignment angle is a protrusion on the bearing surface of the second plate.

[0017] Furthermore, the alignment angle is set at one end of the bearing surface of the second plate and opens inward, thereby enabling the corner of the stamping carrier to be better inserted into the alignment angle.

[0018] Furthermore, the opposing angle is a right triangle. Paper is a common printing medium in daily life, and the edges and corners of paper are generally right angles. Therefore, designing the opposing angle as a right triangle makes it easier to position the printing medium.

[0019] Compared with existing technologies, the advantages of this invention are as follows: the relative positioning between the second plate and the first plate is achieved through the cooperation of the positioning hole and the positioning post, thereby achieving the positioning of the stamp and preventing the stamp from shifting during the stamping process. Simultaneously, the elastic reset structure set between the second and first plates provides auxiliary positioning of the stamping carrier. Furthermore, the stamp experiences uniform force during pressing, which facilitates the even imprinting of text or patterns onto the stamping carrier, improving the stamping effect. The elastic buffering force of the elastic reset structure also provides a better user experience when pressing. Attached Figure Description

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] Example 1:

[0031] like Figures 1-7As shown, a stamping machine includes a first plate 1 and a second plate 2 arranged opposite to each other. The first plate 1 and the second plate 2 can cooperate to press a stamp (generally made of silicone or rubber, with text and / or patterns on one side) and a stamping carrier (paper in this embodiment) located between the first plate 1 and the second plate 2.

[0032] Furthermore, a positioning post 21 is provided on the second plate 2 facing the first plate 1, and a positioning hole 11 is provided on the first plate 1 for the positioning post 21 to be inserted. An elastic reset structure 3 is provided between the second plate 2 and the first plate 1. When the second plate 2 and the first plate 1 are pressed together, the elastic reset structure 3 causes the second plate 2 to tend to separate from the first plate 1. This invention achieves relative positioning between the second plate 2 and the first plate 1 through the cooperation of the positioning hole 11 and the positioning post 21, thereby achieving the positioning of the stamp and preventing displacement of the stamp during the stamping process. Simultaneously, the elastic reset structure 3 provided between the second plate 2 and the first plate 1 provides auxiliary positioning of the stamping carrier and ensures uniform force on the stamp during pressing, which is beneficial for the text or pattern on the stamp to be evenly stamped on the stamping carrier, improving the stamping effect. The elastic buffering force of the elastic reset structure 3 also provides a better user experience when pressing.

[0033] In this embodiment, both the second plate 2 and the first plate 1 are square in shape. The positioning posts 21 are spaced apart along one of the sides of the second plate 2. The positioning holes 11 of the first plate 1 correspond one-to-one with the positioning posts 21 (i.e., when the areas of the second plate 2 and the first plate 1 are equal). Alternatively, the number of positioning holes 11 of the first plate 1 is less than the number of positioning posts 21, and the positioning holes 11 can accommodate any number of corresponding positioning posts 21 (i.e., when the areas of the second plate 2 and the first plate 1 are not equal).

[0034] Specifically, in this embodiment, preferably, the area of ​​the first plate 1 is smaller than that of the second plate 2, and the adjacent sides of each plate are aligned, the length of the first side of the first plate 1 (i.e., the longer side of the first plate 1) is equal to the length of the first side of the second plate 2 (i.e., the shorter side of the first plate 1), while the length of the second side of the first plate 1 (i.e., the shorter side of the second plate 2) is shorter than the length of the second side of the second plate 2 (i.e., the longer side of the second plate 2). The positioning post 21 is arranged along the length direction of the second side of the second plate 2, and the first plate 1 can move back and forth relative to the second plate 2 along the length direction of the second side of the second plate 2. During the movement, the corresponding positioning post 21 on the second plate 2 can be inserted into the corresponding positioning hole 11 of the first plate 1, and the corresponding parts of the lower surface of the first plate 1 and the upper surface of the second plate 2 are always opposite each other. In this way, as the first plate 1 moves along the second plate 2, a straight-line stamping can be achieved on the stamping carrier. That is, as the first plate 1 moves, the text or pattern on the stamp is repeatedly stamped on the stamping carrier along the setting direction of the positioning post 21, thereby achieving continuous stamping of the same text or pattern along a straight line on the stamping carrier.

[0035] The relative arrangement of the second plate 2 and the first plate 1 can be implemented in various ways. In this embodiment, the first plate 1 is located on top of the second plate 2. During use, the stamping carrier is placed on the upper surface of the second plate 2, then the stamp is placed at the desired stamping position. The first plate 1 is then placed on top, aligning the positioning hole 11 with the corresponding positioning post 21 and pressing down. Each elastic reset structure 3 is compressed, and the stamp adheres to the lower surface of the first plate 1. The first plate 1 is then lifted, ink is applied to the stamp, and then the first plate 1 is placed on top and pressed down. The text or pattern on the stamp is then imprinted on the stamping carrier. The first plate 1 is then lifted and moved relative to the second plate 2 along the direction of the positioning post 21, and the above steps are repeated to achieve linear repetitive stamping of the text or pattern on the stamp on the stamping carrier.

[0036] Furthermore, the aforementioned elastic reset structure 3 includes a first mounting groove 12 formed on the lower surface of the first plate 1, a first reset spring 32 installed in the first mounting groove 12, and a pressing cap 31. The upper end of the pressing cap 31 is open and inserted into the first mounting groove 12, and can move up and down along the depth direction of the first mounting groove 12. The first reset spring 32 is limited between the inner bottom surface of the first mounting groove 12 and the inner bottom surface of the pressing cap 31. This ensures a stable installation of the first reset spring 32 and the pressing cap 31, and also allows the first reset spring 32 to provide sufficient pressing elastic force during the pressing process. Preferably, a first guide sleeve 33 is embedded in the first mounting groove 12. The inner circumferential surface of the first guide sleeve 33 is provided with vertically extending first guide grooves 331 spaced circumferentially. The outer surface of the opening end of the pressing cap 31 is provided with first guide protrusions 311 spaced circumferentially, corresponding to the first guide grooves 331. Each first guide protrusion 311 is inserted into its corresponding first guide groove 331 and can move up and down along the first guide groove 331. The cooperation between the first guide protrusions 311 on the pressing cap 31 and the first guide grooves 331 on the first guide sleeve 33 allows the pressing cap 31 to move up and down more smoothly, thereby making the force on the stamp more even. In this embodiment, to achieve a stable installation of the first return spring 32, a first mounting protrusion 121 is vertically fixed on the inner bottom surface of the first mounting groove 12, and the lower end of the first return spring 32 is sleeved on the first mounting protrusion 121. During the assembly process, the pressing cap 31 is first inserted into the first guide sleeve 33, and then the first guide sleeve 33 and the pressing cap 31 are inserted together into the first mounting groove 12, and the first guide sleeve 33 is fixed to the first mounting groove 12.

[0037] Furthermore, preferably, the free end of the pressing cap 31 is provided with an anti-slip pad 4. By providing the anti-slip pad 4, the first plate 1 can be prevented from moving laterally on the stamping carrier, thereby improving the stability of the stamping positioning. Further, as... Figure 6 and Figure 7 As shown, the bearing surface 20 (i.e., the plane for placing the stamping carrier) of the second plate 2 is provided with an alignment angle 23 that matches one of the corners of the stamping carrier and allows that corner to be aligned. In this way, the alignment angle 23 is set to achieve the alignment of the stamping carrier in this invention, ensuring the accuracy of the stamping position, especially when stamping the corners of the stamping carrier.

[0038] There are various ways to implement the aforementioned alignment angle 23. In this embodiment, the alignment angle 23 is a line provided on the bearing surface 20 of the second plate 2. This line can be implemented in various ways, such as a scribe line recessed on the bearing surface 20 of the second plate 2, or a printed line printed on the bearing surface 20 of the second plate 2. In this embodiment, the line is preferably a scribe line recessed on the bearing surface 20 of the second plate 2. At the same time, the alignment angle 23 is provided at one end of the bearing surface 20 of the second plate 2 and opens inward, so that the corner of the stamping carrier can be better inserted into the alignment angle 23.

[0039] Specifically, in this embodiment, the aforementioned opposing angle 23 is a right triangle. Paper is a common printing medium in daily life, and the edges and corners of paper are generally right angles. Therefore, designing the opposing angle 23 as a right triangle makes it easier to position the printing medium.

[0040] In this embodiment, the second plate 2 is square in shape, and the aligning angle 23 is located at the left end of the second plate 2, with the angle bisector of the aligning angle 23 parallel to the upper or lower end of the second plate 2. This facilitates the placement of the aligning angle 23 on the bearing surface 20, and when the corner of the stamping carrier is engaged with the aligning angle 23, the stamping carrier is positioned directly opposite the second plate 2, which is more conducive to stamping in the correct position on the stamping carrier. Preferably, the aligning angle 23 is located in the middle of the left end of the second plate 2, which allows the stamping carrier to be placed flat on the second plate 2. When the cover plate 1 of the stamping machine is placed on the second plate 2, the pressure on the stamping carrier is more uniform, which is beneficial to improving the stamping effect.

[0041] Furthermore, a positioning structure protrudes from one end of the second plate 2 along its length. This positioning structure can be implemented in various ways, such as protruding strips, spaced protrusions, or spaced protruding pillars. In this embodiment, preferably, the positioning structure is a positioning protrusion 22 spaced along the length of one end of the second plate 2, with each positioning protrusion 22 perpendicular to the bearing surface 20 of the second plate 2. Thus, the positioning protrusion 22, arranged along a straight line, can position one side of the stamping carrier. That is, the stamping machine of this invention, in addition to using the alignment angle 23 to achieve angular positioning of the stamping carrier, can also achieve edge positioning of the stamping carrier through the positioning protrusion 22. Preferably, both the positioning protrusion 22 and the alignment angle 23 are located at the left end of the second plate 2, and the positioning protrusion 22 and the alignment angle 23 are staggered along the length of the left end of the second plate 2, thereby facilitating the user's positioning operation of the stamping carrier.

[0042] In this embodiment, the free ends of both sides of the aforementioned alignment angle 23 are located on the same straight line as each positioning protrusion 22, and two of the positioning protrusions 22 are respectively adjacent to the two sides of the alignment angle 23. Thus, when using the alignment angle 23 to perform angular positioning of the stamping carrier, the positioning protrusions 22 on both sides of the alignment angle 23 can play an auxiliary positioning role, thereby improving the positioning effect of the alignment angle 23. Preferably, among the two positioning protrusions 22 adjacent to the two sides of the aforementioned alignment angle 23, the inner surface of each positioning protrusion 22 is a guide slope 221 on the same plane as the opposite side of the alignment angle 23. The guide slopes 221 on the positioning protrusions 22 on both sides guide the corners of the stamping carrier to be positioned into the alignment angle 23, allowing the user to more conveniently position the corners of the stamping carrier.

[0043] Example 2:

[0044] like Figure 8 As shown, unlike Embodiment 1, in this embodiment, the alignment angle 23 is a groove formed by the downward-facing recess of the bearing surface 20 of the second plate 2. Thus, the alignment angle 23 not only aligns the stamping carrier but also positions it, preventing displacement during the stamping process and ensuring stamping quality.

[0045] Example 3:

[0046] like Figure 9 As shown, unlike Embodiment 1, in this embodiment, the alignment angle 23 is a protrusion on the bearing surface 20 of the second plate 2. That is, the alignment angle 23 is a bent protrusion on the bearing surface 20. In addition to aligning the stamping carrier, it can also position the stamping carrier and prevent the stamping carrier from shifting during the stamping process.
