A stamping machine

Abstract

This invention relates to a stamping machine, comprising a first plate and a second plate arranged vertically opposite each other. The first and second plates cooperate to press a stamp and a stamping carrier located between the first and second plates. The first plate has a positioning hole, while the second plate has an elastic positioning structure that can be confined within the positioning hole. When the first plate is pressed towards the second plate, the elastic positioning structure causes the first plate to tend to move away from the second plate. This invention achieves relative positioning between the first and second plates through the cooperation of the positioning hole and the elastic positioning structure, thereby achieving stamp positioning, preventing stamp displacement during the stamping process, and ensuring even force distribution on the stamp, which is beneficial for the text or pattern on the stamp to be evenly stamped onto the stamping carrier.

Description

Technical Field

[0001] This invention relates to the field of hand tools, and more particularly to the field of pattern stamping technology, specifically to a stamping machine. Background Technology

[0002] A stamping machine is a device that uses the pressure of two plates to transfer ink through the graphic portion onto a substrate. With a stamping machine, consumers can print their favorite designs on paper, clothing, or other stamping media. For example, Chinese invention patent application number CN201811045056.3 (publication number CN 109353135 A) discloses a stamping machine, including a body (1). The body (1) includes a base plate (2) for placing the substrate and the stamp, a pressure plate (3) that cooperates with the base plate (2) to press the substrate and the stamp, and a magnetic attraction structure (4) that generates mutual attraction between the pressure plate (3) and the base plate (2). The upper surface of the base plate (2) is provided with a working space (21) for placing the substrate and the stamp.

[0003] Compared with ordinary manual stamping, stamping machines can produce a wider variety of stamped patterns and are more convenient to use. However, existing stamping machines generally have the following problems: (1) The positioning between the two plates is not stable, and the stamp is prone to displacement during the stamping process, resulting in misaligned or blurred stamped patterns, which affects the stamping quality; (2) The stamp is subjected to uneven force during the stamping process, resulting in uneven color of the stamped pattern, which requires reprinting, affecting the stamping quality and user experience; (3) If the pattern is incomplete after the first stamping, it is difficult to ensure that the two stamped patterns overlap because the positioning cannot be accurately repeated. Summary of the Invention

[0004] The first technical problem to be solved by the present invention is to provide a stamping machine that facilitates stamp positioning, in contrast to the prior art.

[0005] The second technical problem to be solved by the present invention is to provide a stamping machine that facilitates the positioning of the stamp and the stamping carrier, in contrast to the prior art.

[0006] The third technical problem to be solved by the present invention is to provide a stamping machine that is not limited by the size of the stamping carrier, in contrast to the prior art.

[0007] The technical solution adopted by the present invention to solve at least one of the above-mentioned technical problems is as follows: a stamp stamping machine, comprising a first plate and a second plate arranged vertically opposite to each other, wherein the first plate and the second plate can cooperate to press a stamp and a stamping carrier located between the first plate and the second plate, characterized in that the first plate is provided with a positioning hole, and the second plate is provided with an elastic positioning structure that can be limited in the positioning hole, wherein when the first plate is pressed toward the second plate, the elastic positioning structure causes the first plate to have a tendency to move away from the second plate.

[0008] Furthermore, the elastic positioning structure includes a vertically extending column with a positioning protrusion at its top. The size of the positioning protrusion matches the size of the positioning hole on the first plate. The column also has a resting part, on which the first plate rests after being inserted into the positioning protrusion through its positioning hole. Thus, when the positioning protrusion engages with the positioning hole, a stable positioning is formed between the elastic positioning structure and the positioning hole, thereby creating a stable positioning between the first plate and the second plate.

[0009] Furthermore, the positioning protrusion extends integrally to the center of the top surface of the column, and the top surface of the column slopes downwards from the inside to the outside in a circumferential direction around the positioning protrusion to form the resting part. The lower hole of the positioning hole is recessed outwards in a circumferential direction to form a resting groove that matches the outer surface of the top. In the installed state, the positioning protrusion is engaged in the positioning hole, and the resting part of the column is engaged in the resting groove. On the one hand, the cooperation between the resting part and the resting groove facilitates the insertion of the positioning protrusion into the positioning hole; on the other hand, the engagement of the resting part with the resting groove makes the positioning between the positioning hole and the positioning protrusion more stable.

[0010] Furthermore, the elastic positioning structure also includes a first mounting groove formed on the upper surface of the second plate and extending vertically. A first return spring is installed in the first mounting groove. The lower end of the column is inserted into the first mounting groove and can move back and forth along the depth direction of the first mounting groove. The first return spring is limited between the inner bottom surface of the first mounting groove and the inner top surface of the column. This achieves a stable installation of the first return spring and the column, and also ensures that the first return spring provides sufficient pressing elastic force during the pressing process.

[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 lower end of the aforementioned column 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 back and forth along that groove. The cooperation between the first guide protrusions on the column and the first guide grooves on the first guide sleeve allows the column to move up and down more smoothly, thereby providing a more stable downward pressure on the stamp, resulting in more uniform and complete imprinted text or patterns.

[0012] Furthermore, the first or second plate is also provided with an elastic reset structure. When the first plate is pressed, the elastic reset structure and the elastic positioning structure are compressed synchronously, causing the first plate to tend to move away from the second plate. The cooperation between the elastic reset structure and the elastic positioning structure makes the force on the stamp more uniform during the pressing process, thereby further improving the stamping quality.

[0013] Furthermore, the elastic reset structure is disposed on the first plate. This elastic reset structure includes a second mounting groove formed on the inner surface of the first plate and extending along the thickness direction of the first plate, a second reset spring installed in the second mounting groove, and a pressing cap. The upper end of the pressing cap is inserted into the second mounting groove and can move back and forth along the depth direction of the second mounting groove. The second reset spring is confined between the inner bottom surface of the second mounting groove and the inner bottom surface of the pressing cap. This achieves a stable installation of the second reset spring and the column, and ensures that the second reset spring provides sufficient pressing elastic force during the pressing process.

[0014] Furthermore, a second guide sleeve is embedded in the second mounting groove. The inner circumferential surface of the second guide sleeve has vertically extending second guide grooves spaced at intervals along the circumference. The outer surface of the upper end of the pressing cap has second guide protrusions spaced at intervals along the circumference, each corresponding to one of the second guide grooves. Each second guide protrusion is inserted into its corresponding second guide groove and can move back and forth along that groove. The cooperation between the second guide protrusions on the pressing cap and the second guide grooves on the second guide sleeve allows the pressing cap to move up and down more smoothly, thereby ensuring more even force distribution on the stamp.

[0015] Furthermore, an anti-slip pad is provided at the free end of the pressing cap. By providing the anti-slip pad, the first plate can be prevented from moving laterally on the stamping carrier, thereby improving the stability of the stamping positioning.

[0016] Furthermore, at least two elastic positioning structures are spaced apart at one end of the second plate, and at least two elastic reset structures are spaced apart at the other end of the first plate. Correspondingly, at least two positioning holes are also present on the first plate, each corresponding to one of the elastic positioning structures. This ensures more stable positioning between the first and second plates and more even force distribution on the stamp.

[0017] Furthermore, the first plate is located on top of the second plate, which includes a plate body and a positioning block. The positioning block is detachably disposed at one end of the upper surface of the plate body, and its bottom surface is flat, forming a clamping space between the positioning block and the upper surface of the plate body to hold the stamping carrier. The aforementioned elastic positioning structure is disposed on the positioning block. Because the elastic positioning structure is disposed on the positioning block, and the bottom surface of the positioning block forms a clamping space with the upper surface of the plate body, the elastic positioning structure no longer limits the area of ​​the stamping carrier, theoretically allowing for an infinitely large area of ​​stamping carrier to which this invention is applicable.

[0018] Furthermore, the positioning block and the plate body are magnetically connected by a magnetic attraction assembly, which facilitates the assembly and disassembly of the positioning block and the plate body.

[0019] Furthermore, the magnetic suction assembly includes a first magnetic suction block embedded in the bottom surface of the positioning block and a second magnetic suction block embedded in the upper surface of the plate body. This better forms the aforementioned clamping space, thereby better avoiding limitations on the size of the stamping carrier area.

[0020] Furthermore, both the first plate and the plate body are square in shape. The positioning block is located at one end of the plate body and extends along the length of the plate body at that location. The first plate, opposite to the positioning block, is bent upwards along its length to form a positioning boss into which the positioning block is inserted. The height of the positioning boss matches the thickness of the positioning block, and the positioning hole is formed on the horizontal wall of the positioning boss. This better facilitates the assembly and positioning between the first and second plates and allows the first and second plates to better clamp the stamp and stamping carrier.

[0021] Compared with existing technologies, the advantages of this invention are as follows: The relative positioning between the first and second plates is achieved through the cooperation of the positioning hole and the elastic positioning structure, thereby positioning the stamp and preventing displacement during the stamping process. Simultaneously, when the first plate is pressed, the elastic positioning structure causes it to tend to move away from the second plate, ensuring even force distribution on the stamp and facilitating the uniform imprinting of text or patterns onto the stamping carrier, thus improving stamping quality. Furthermore, the elastic cushioning force of the elastic positioning structure provides a better user experience when pressing. In addition, compared with traditional magnetic positioning, the positioning hole and elastic positioning structure of this invention further improve positioning accuracy while reducing the production cost of the stamping machine.

[0031] Figure 10 for Figure 9 A structural diagram from another direction. Detailed Implementation

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] Example 1:

[0034] like Figures 1-6 As shown, a stamping machine includes a first plate 1 and a second plate 2 disposed opposite to each other. The first plate 1 and the second plate 2 can cooperate to press a stamp and a stamping carrier located between the first plate 1 and the second plate 2. The first plate 1 is provided with a positioning hole 11, and the second plate 2 is provided with an elastic positioning structure 3 that can be limited in the positioning hole 11. When the first plate 1 is pressed towards the second plate 2, the elastic positioning structure 3 causes the first plate 1 to tend to move away from the second plate 2. The relative positioning between the first plate 1 and the second plate 2 can be achieved through the cooperation of the positioning hole 11 and the elastic positioning structure 3, thereby achieving the positioning of the stamp and preventing the stamp from shifting during the stamping process. At the same time, when the first plate 1 is pressed, the elastic positioning structure 3 makes the first plate 1 tend to move away from the second plate 2. This makes the stamp evenly stressed, which is conducive to the text or pattern on the stamp being evenly stamped on the stamping carrier, improving the stamping quality. Meanwhile, the elastic buffering force of the elastic positioning structure 3 also provides users with a better user experience when pressing.

[0035] The relative arrangement of the first plate 1 and the second plate 2 can be implemented in various ways. In this embodiment, the first plate 1 is located on the second plate 2. When in use, the stamping carrier (paper in this embodiment) is placed on the upper surface of the second plate 2. Then, the stamp (generally made of silicone or rubber, with text and / or patterns on one side) is placed on the position to be stamped. The first plate 1 is then placed on top, the positioning hole 11 is aligned with the elastic positioning structure 3 and pressed down, and the stamp is adsorbed on the lower surface of the first plate 1. The first plate 1 is then picked up, ink is applied to the stamp, and then the first plate 1 is placed on top and pressed down. The text or patterns on the stamp are then printed on the stamping carrier.

[0036] Furthermore, in this embodiment, the first plate 1 is also provided with an elastic reset structure 4. When the first plate 1 is pressed, the elastic reset structure 4 and the elastic positioning structure 3 are compressed synchronously, causing the first plate 1 to tend to move away from the second plate 2. The elastic reset structure 4 can achieve auxiliary positioning of the stamping carrier, and the cooperation between the elastic reset structure 4 and the elastic positioning structure 3 can make the force on the stamp more uniform during the pressing process, thereby further improving the stamping quality.

[0037] Specifically, in this embodiment, both the first plate 1 and the second plate 2 are square flat plates. The elastic positioning structure 3 is provided at each of the two corners of one end of the second plate 2, while the positioning holes 11 corresponding to the elastic positioning structures 3 are provided at the corresponding corners of the first plate 1. Simultaneously, the elastic reset structure 4 is provided at each of the two corners of the other end of the first plate 1. This ensures a more stable positioning between the first plate 1 and the second plate 2, and also makes the force on the stamp more even.

[0038] Furthermore, in this embodiment, each of the aforementioned elastic positioning structures 3 includes a vertically extending column 31. The top of the column 31 has a positioning protrusion 311, the size of which matches the size of the positioning hole 11 on the first plate 1. The column 31 is provided with a resting part 310. The first plate 1 is inserted into the positioning protrusion 311 through its positioning hole 11 and then rests on the resting part 310. In this way, when the positioning protrusion 311 is engaged in the positioning hole 11, a stable positioning can be formed between the elastic positioning structure 3 and the positioning hole 11, thereby forming a stable positioning between the first plate 1 and the second plate 2. Preferably, in each elastic positioning structure 3, the positioning protrusion 311 extends integrally to the middle of the top surface of the column 31, and the top surface of the column 31 slopes downward from the inside to the outside in the circumferential direction around the positioning protrusion 311 to form the resting portion 310. The lower hole of the positioning hole 11 is recessed outward in the circumferential direction to form a resting groove 111 that matches the resting portion 310. In the installed state, the positioning protrusion 311 is engaged in the positioning hole 11, and the resting portion 310 of the column 31 is engaged in the resting groove 111. On the one hand, the cooperation between the resting portion 310 of the column 31 and the resting groove 111 facilitates the insertion of the positioning protrusion 311 into the positioning hole 11. On the other hand, the engagement of the resting portion 310 of the column 31 into the resting groove 111 makes the positioning between the positioning hole 11 and the elastic positioning structure 3 more stable.

[0039] Specifically, in this embodiment, each elastic positioning structure 3 further includes a first mounting groove 21 formed on the upper surface of the second plate 2 and extending vertically. A first return spring 32 is installed in the first mounting groove 21. The column 31 is a hollow structure with an open lower end. The open end of the column 31 is inserted into the first mounting groove 21 and can move up and down along the depth direction of the first mounting groove 21. The first return spring 32 is limited between the inner bottom surface of the first mounting groove 21 and the inner top surface of the column 31. On the one hand, it can achieve a stable installation of the first return spring 32 and the column 31. On the other hand, the first return spring 32 can provide sufficient pressing elastic force during the pressing process. Preferably, each of the aforementioned first mounting slots 21 is fitted with a first guide sleeve 33. 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 lower end of the aforementioned column 31 is provided with first guide protrusions 312 spaced circumferentially, corresponding one-to-one with the first guide grooves 331. Each first guide protrusion 312 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 312 on the column 31 and the first guide grooves 331 on the first guide sleeve 33 allows the column 31 to move up and down more smoothly, thereby providing a more stable downward pressure on the stamp, resulting in more uniform and complete imprinted text or patterns. In this embodiment, to achieve stable installation of the aforementioned first return spring 32, a first mounting protrusion 211 is vertically fixed on the inner bottom surface of the aforementioned first mounting slot 21, and the lower end of the aforementioned first return spring 32 is sleeved on the first mounting protrusion 211. During assembly, first insert the upper end of the column 31 into the first guide sleeve 33, then insert the column 31 and the first guide sleeve 33 together into the first mounting groove 21 and fix the first guide sleeve 33 to the first mounting groove 21.

[0040] Furthermore, each elastic reset structure 4 includes a second mounting groove 12 formed on the inner surface of the first plate 1 and extending along the thickness direction of the first plate 1, a second reset spring 42 installed in the second mounting groove 12, and a pressing cap 41. The upper end of the pressing cap 41 is open and inserted into the second mounting groove 12 and can move up and down along the depth direction of the second mounting groove 12. The second reset spring 42 is limited between the inner bottom surface of the second mounting groove 12 and the inner bottom surface of the pressing cap 41. This ensures a stable installation of the second reset spring 42 and the pressing cap 41, and also allows the second reset spring 42 to provide sufficient pressing elastic force during the pressing process. Preferably, a second guide sleeve 43 is embedded in the second mounting groove 12. The inner circumferential surface of the second guide sleeve 43 is provided with vertically extending second guide grooves 431 spaced circumferentially. The outer surface of the opening end of the pressing cap 41 is provided with second guide protrusions 411 spaced circumferentially, corresponding to the second guide grooves 431. Each second guide protrusion 411 is inserted into its corresponding second guide groove 431 and can move up and down along the groove. The cooperation between the second guide protrusions 411 on the pressing cap 41 and the second guide grooves 431 on the second guide sleeve 43 allows the pressing cap 41 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 second return spring 42, a second mounting protrusion 121 is vertically fixed on the inner bottom surface of the second mounting groove 12, and the lower end of the second return spring 41 is sleeved on the second mounting protrusion 121. During assembly, firstly, the lower end of the pressing cap 41 is inserted into the second guide sleeve 43. Then, the pressing cap 41 and the second guide sleeve 43 are inserted together into the second mounting groove 12, and the second guide sleeve 43 is fixed to the second mounting groove 12. More preferably, the free end of the pressing cap 41 is provided with an anti-slip pad 412. By providing the anti-slip pad 412, the first plate 1 can be prevented from moving laterally on the stamping carrier, thereby improving the stability of the stamping positioning.

[0041] Example 2:

[0042] Unlike Example 1, as Figures 7-10As shown, in this embodiment, the second plate 2 includes a plate body 201 and a positioning block 202. The positioning block 202 is detachably disposed at one end of the upper surface of the plate body 201, and the bottom surface of the positioning block 202 is flat, forming a clamping space for clamping the stamping carrier between it and the upper surface of the plate body 201. The elastic positioning structure 3 is disposed on the positioning block 202, and the positioning hole 11 is formed at the position opposite to the positioning block 202 on the first plate 1. Since the elastic positioning structure 3 is disposed on the positioning block 202, and a clamping space is formed between the bottom surface of the positioning block 202 and the upper surface of the plate body 201, the elastic positioning structure 3 no longer restricts the area size of the stamping carrier, so the area size of the stamping carrier applicable in this invention can theoretically be infinitely large.

[0043] The detachable connection between the positioning block 202 and the plate body 201 can be implemented in various ways. In this embodiment, preferably, the positioning block 202 and the plate body 201 are magnetically connected by a magnetic absorbing assembly, thereby facilitating the assembly and disassembly of the positioning block 202 and the plate body 201. Specifically, the magnetic absorbing assembly includes a first magnetic absorbing block 51 embedded on the bottom surface of the positioning block 202 and a second magnetic absorbing block 52 embedded on the upper surface of the plate body 201. The exposed surface of the first magnetic absorbing block 51 is substantially flush with the bottom surface of the positioning block 202, and the exposed surface of the second magnetic absorbing block 52 is substantially flush with the upper surface of the plate body 201. This better forms the clamping space, thereby better avoiding limitations on the size of the stamping carrier area. Preferably, the outer periphery of the first magnetic block 51 is provided with an anti-slip washer 511, the bottom surface of which is slightly higher than the bottom surface of the first magnetic block 51. In this way, by setting the anti-slip washer 511, it can prevent the first magnetic block 51 and the second magnetic block 52 from being damaged by impact during the mutual magnetic attraction process, and on the other hand, it can prevent the lateral sliding between the positioning block 202 and the plate body 201.

[0044] Specifically, in this embodiment, both the first plate 1 and the second plate 2 are square in shape. The positioning block 202 is disposed at one end of the plate body 201 and extends along the length of the plate body 201 at that location. The first plate 1, opposite to the positioning block 202, is bent upward along the length of the first plate 1 at that location to form a positioning boss 13 into which the positioning block 202 is inserted. The height of the positioning boss 13 matches the thickness of the positioning block 202, and the positioning hole 11 is formed on the horizontal wall of the positioning boss 13. This allows for better assembly and positioning between the first plate 1 and the second plate 2, and enables the first plate 1 and the second plate 2 to better clamp the stamp and the stamping carrier.
