[0031] Please refer to Figures 1 to 8 , the present utility model provides a replaceable printing surface roller seal, including a main body assembly 1, a roller assembly 2 and a bottom cover 3. Both ends of the roller assembly 2 are clamped on the main body assembly 1 and can make a circular motion relative to the main body assembly 1, and the bottom cover 3 is detachably connected to the main body assembly 1;

[0032] The roller assembly 2 includes a roller shaft 21, an ink storage member 22, and a stamp pad 23. The ink storage member 22 is embedded on the roller shaft 21 and is disposed between the roller shaft 21 and the stamp pad 23. The stamp pad 23 is detachably connected to the roller shaft 21.

[0033] In this embodiment, the roller stamp with a replaceable printing surface includes a main body assembly 1, a roller assembly 2, and a bottom cover 3. Both ends of the roller assembly 2 are clamped inside the main body assembly 1, and the roller assembly 2 can perform a circular motion relative to the main body assembly 1. When the user holds the main body assembly 1 and pushes the roller assembly 2, the roller assembly 2 can be used to stamp on the surface of the object to be stamped. The bottom of the main body assembly 1 is also detachably connected with a bottom cover 3. When the main body assembly 1 and the bottom cover 3 are connected, the main body assembly 1 and the bottom cover 3 form an accommodation space, and the roller assembly 2 is accommodated in this accommodation space. When the bottom cover 3 is detached from the main body assembly 1, the roller assembly 2 can be used for stamping. That is, when it is necessary to stamp through the roller assembly 2, only the bottom cover 3 needs to be pulled off the main body assembly 1. When the stamping is completed, the bottom cover 3 can be snapped back onto the main body assembly 1.

[0034] In this embodiment, the roller assembly 2 includes a roller shaft 21, an ink storage member 22, and a stamp pad 23. The ink storage member 22 and the stamp pad 23 are respectively connected to the roller shaft 21. Specifically, the ink storage member 22 is embedded on the roller shaft 21 and is used for storing ink. The ink storage member 22 is disposed between the roller shaft 21 and the stamp pad 23 and is used for supplying ink to the stamp pad 23, so that the stamp pad 23 can fully absorb the ink on the ink storage member 22. Among them, patterns are formed on the printing surface of the stamp pad 23 by methods such as photosensitive exposure, and then through pigments such as ink on the ink storage member 22, and then the roller shaft 21 performs a circular motion relative to the main body assembly 1, so that the patterns on the stamp pad 23 can be printed on documents or other objects.

[0035] Specifically, since the stamp pad 23 of the existing roller stamp is generally fixed on the roller stamp, if it is necessary to print multiple different patterns, multiple roller stamps need to be customized. This method greatly increases the use cost of the roller stamp and results in poor applicability of the roller stamp. However, in the embodiment of the present application, the stamp pad 23 is detachably connected to the roller shaft 21, so that it is convenient to disassemble and replace the stamp pad 23 on the roller shaft 21. The contents on multiple stamp pads 23 can be backed up, so that the roller stamp can have rich patterns and the content of the patterns is more flexible, reducing the use cost of the roller stamp and improving the applicability of the roller stamp and the user experience.

[0036] Further, the roller 21 includes a first ink cartridge 211 and a second ink cartridge 212. One end of the first ink cartridge 211 and the second ink cartridge 212 is rotatably connected, and the other ends are oppositely arranged and are respectively provided with a plurality of protruding members 4. Both ends of the stamp pad 23 are respectively provided with a plurality of limiting holes adapted to the protruding members 4. Both ends of the stamp pad 23 are detachably connected to the protruding members 4 on the first ink cartridge 211 and the second ink cartridge 212 through the limiting holes.

[0037] In this embodiment, the roller 21 includes a split first ink cartridge 211 and a second ink cartridge 212. Both the first ink cartridge 211 and the second ink cartridge 212 can be used to add ink, and the two ink cartridges can add inks of different colors, so that the roller stamp in the embodiment of the present application can store inks of multiple colors, while the ink cartridges of existing stamps can only add a single color of ink.

[0038] Specifically, one end of the first ink cartridge 211 and one end of the second ink cartridge 212 are rotatably connected, and the other ends are oppositely arranged. The oppositely arranged ends of the first ink cartridge 211 and the second ink cartridge 212 are respectively provided with a plurality of protruding members 4. A plurality of protruding members 4 for connecting the stamp pad 23 are respectively arranged on the two ink cartridges, so that the stamp pad 23 can be connected to the roller 21. Both ends of the stamp pad 23 are respectively provided with a plurality of limiting holes. The plurality of limiting holes at both ends of the stamp pad 23 are correspondingly arranged with the protruding members 4 at the oppositely arranged ends of the first ink cartridge 211 and the second ink cartridge 212. The number and shape of the limiting holes on the stamp pad 23 are adapted to the number and shape of the protruding members 4 on the first ink cartridge 211 and the second ink cartridge 212. Furthermore, the stamp pad 23 can be connected to the protruding members 4 at the oppositely arranged ends of the first ink cartridge 211 and the second ink cartridge 212 through the plurality of limiting holes at both ends, that is, one end of the head of the stamp pad 23 is connected to the protruding member 4 of the first ink cartridge 211 / the second ink cartridge 212 through the limiting hole, and the other end of the tail is also connected to the protruding member 4 of the second ink cartridge 212 / the first ink cartridge 211 through the limiting hole.

[0039] When the stamp pad 23 needs to be installed on the roller 21, only need to hang the limiting holes at both ends of the stamp pad 23 into the protruding members 4 at the oppositely arranged ends of the first ink cartridge 211 and the second ink cartridge 212 respectively; when the stamp pad 23 on the roller 21 needs to be replaced, pull out the limiting holes at both ends of the stamp pad 23 from the protruding members 4 on the first ink cartridge 211 and the second ink cartridge 212.

[0040] Wherein, the specific shape of the protruding member 4 in this embodiment is cylindrical. The shape of the protruding member 4 is not limited herein and can be rectangular, square, triangular, etc., and is set according to actual production requirements.

[0041] Further, a first pressing edge member 213 and a second pressing edge member 214 are respectively detachably connected to a plurality of protruding members 4 on the first ink cartridge 211 and the second ink cartridge 212. Both ends of the first pressing edge member 213 and the second pressing edge member 214 are respectively clamped on the first ink cartridge 211 and the second ink cartridge 212. Both ends of the seal pad 23 are respectively arranged between the first pressing edge member 213 and the second pressing edge member 214 and the first ink cartridge 211 and the second ink cartridge 212. The first pressing edge member 213 and the second pressing edge member 214 are snap-connected.

[0042] In this embodiment, a first pressing edge member 213 and a second pressing edge member 214 are respectively detachably connected to a plurality of protruding members 4 on opposite ends of the first ink cartridge 211 and the second ink cartridge 212. When the limiting holes at the head and tail ends of the seal pad 23 are respectively clamped on the protruding members 4 on the first ink cartridge 211 and the second ink cartridge 212, then the first pressing edge member 213 and the second pressing edge member 214 are respectively clamped on the protruding members 4 on the first ink cartridge 211 and the second ink cartridge 212, that is, the head and tail ends of the seal pad 23 are clamped between the first pressing edge member 213 and the second pressing edge member 214 and the first ink cartridge 211 and the second ink cartridge 212. Thus, the head and tail ends of the seal pad 23 can be fixedly pressed on the first ink cartridge 211 and the second ink cartridge 212 through the first pressing edge member 213 and the second pressing edge member 214, and further the seal pad 23 can be firmly installed on the first ink cartridge 211 and the second ink cartridge 212 on the roller 21. Among them, a plurality of limiting holes adapted to the protruding members 4 are also provided on the first pressing edge member 213 and the second pressing edge member 214, and a snap member and a slot for snap connection are provided on the first pressing edge member 213 and the second pressing edge member 214, so that the first ink cartridge 211 and the second ink cartridge 212 can be better connected. Among them, the first pressing edge member 213 and the second pressing edge member 214 are specifically pressing edge strips in this embodiment.

[0043] Specifically, both ends of the first pressing edge member 213 and the second pressing edge member 214 are respectively snap-connected to both ends of the first ink cartridge 211 and the second ink cartridge 212, so that the limiting holes on the first pressing edge member 213 and the second pressing edge member 214 can be firmly clamped on the protruding members 4 on the first ink cartridge 211 and the second ink cartridge 212, and further the installation of the seal pad 23 can be more firm. When it is necessary to remove the seal pad 23 from the roller 21, it is necessary to first remove the first pressing edge member 213 and the second pressing edge member 214 from the first ink cartridge 211 and the second ink cartridge 212, and then remove the seal pad 23 from the first ink cartridge 211 and the second ink cartridge 212, so as to facilitate replacement.

[0044] Further, the seal pad 23 is sleeved on the outer side of the roller 21. Both ends of the seal pad 23 provided with limiting holes are bent towards the directions of the first ink cartridge 211 and the second ink cartridge 212 respectively, and are respectively connected to the protruding members 4 on the first ink cartridge 211 and the second ink cartridge 212.

[0045] In this embodiment, the stamp pad 23 is sleeved on the outside of the roller 21, so that when the roller 21 rolls, it can drive the stamp pad 23 to stamp. Specifically, one end of the head of a plurality of limiting holes provided on the stamp pad 23 is bent towards the first ink cartridge 211 / the second ink cartridge 212, and one end of the tail is bent towards the second ink cartridge 212 / the first ink cartridge 211, which is more convenient for the connection between the limiting holes at both ends of the stamp pad 23 and the protruding parts 4 on the first ink cartridge 211 and the second ink cartridge 212 of the roller 21. Among them, the thickness of both ends of the stamp pad 23 can be made thinner than the middle position of the stamp pad 23 by hot pressing and edge finishing at both ends, and then small round holes are made at both ends, so that both ends of the stamp pad 23 can be better bent and sleeved on the protruding parts 4 on the first ink cartridge 211 and the second ink cartridge 212, and the arcs of the first edge pressing part 213 and the second edge pressing part 214 respectively match the bending arcs of both ends of the stamp pad 23, and can be better pressed on both ends of the stamp pad 23, and a plastic edge is also provided thereon, and the plastic edge can block both ends of the stamp pad 23, making the roller stamp more beautiful.

[0046] Furthermore, a first connecting piece 2111 is provided at one end of the first ink cartridge 211, two second connecting pieces 2121 are spaced apart at one end of the second ink cartridge 212, and a connecting rod 5 passes through and connects the first connecting piece 2111 and the two spaced second connecting pieces 2121, so that the first ink cartridge 211 and the second ink cartridge 212 are rotationally connected to form a cylindrical roller 21, and the first ink cartridge 211 and the second ink cartridge 212 can be relatively close to or far from each other through the connecting rod 5.

[0047] In this embodiment, a first connecting piece 2111 is provided at one end of the first ink cartridge 211, and two second connecting pieces 2121 are spaced apart at one end of the second ink cartridge 212 where it is rotationally connected to the first ink cartridge 211, and the first connecting piece 2111 is correspondingly arranged at the spaced position between the two second connecting pieces 2121. And the first ink cartridge 211 and the second ink cartridge 212 are sequentially connected through the connecting rod 5 passing through the first connecting piece 2111 and the second connecting piece 2121 thereon, so that the first ink cartridge 211 and the second ink cartridge 212 are rotationally connected in an alternating manner, and the first ink cartridge 211 and the second ink cartridge 212 form a cylindrical roller 21. And the first ink cartridge 211 and the second ink cartridge 212 can be relatively close to or far from each other through the connecting rod 5, that is, the first ink cartridge 211 and the second ink cartridge 212 are relatively opened or closed, so that the first ink cartridge 211 and the second ink cartridge 212 can be opened at a certain angle, thus facilitating the addition of ink into the first ink cartridge 211 and the second ink cartridge 212.

[0048] Specifically, the roller 21 extends diametrically along the length of the cylinder to divide the cross-section into two halves, namely the first ink cartridge 211 and the second ink cartridge 212 which are two semi-cylindrical bodies. The edges in the length direction of the first ink cartridge 211 and the second ink cartridge 212 of the two semi-cylindrical bodies are rotationally connected in an interleaved manner by a connecting rod 5, and multiple protruding members 4 are respectively provided on the other edges in the length direction.

[0049] Among them, in existing roller stamps, ink is injected through a round hole on one side of the ink cartridge. In the embodiment of the present application, the roller 21 is divided into two ink cartridges, and can be opened horizontally from the middle of the roller 21, so that the two ink cartridges are opened at a certain angle, and then different colors of ink are injected into the two ink cartridges.

[0050] Furthermore, a snap groove and a snap member 2122 are respectively provided on the opposite sides of the first ink cartridge 211 and the second ink cartridge 212. The first ink cartridge 211 and the second ink cartridge 212 are snap-connected through the snap groove and the snap member 2122, and a pressing member 2112 is also connected to the snap groove. Pressing the pressing member 2112 can make the snap member 2122 move away from the snap groove, so that the first ink cartridge 211 and the second ink cartridge 212 move relatively away from each other.

[0051] In this embodiment, a snap groove is provided on the first ink cartridge 211, and a snap member 2122 is provided on the second ink cartridge 212. The snap groove and the snap member 2122 can be adaptively snapped together. The first ink cartridge 211 and the second ink cartridge 212 are respectively snap-connected through the snap groove and the snap member 2122. The snap member 2122 approaching or moving away from the snap groove can make the second ink cartridge 212 and the first ink cartridge 211 close or open.

[0052] Specifically, a pressing member 2112 is also provided on the snap groove. When the second ink cartridge 212 is snapped into the snap groove on the first ink cartridge 211 through the snap member 2122, the first ink cartridge 211 and the second ink cartridge 212 are snap-connected. If it is necessary to open the second ink cartridge 212 and the first ink cartridge 211 for refilling ink, only need to press the pressing member 2112 connected to the snap groove, then the snap member 2122 in the snap groove can be snapped out of the snap groove, and the first ink cartridge 211 and the second ink cartridge 212 are also opened at a certain angle, thus facilitating ink refilling. After the ink refilling is completed, then snap the snap member 2122 in the second ink cartridge 212 into the snap groove of the first ink cartridge 211, and the first ink cartridge 211 and the second ink cartridge 212 can be closed.

[0053] Furthermore, a plurality of annular runway holes are respectively provided on the first ink cartridge 211 and the second ink cartridge 212. A sunken arc surface is respectively provided on the outer circumferences of the first ink cartridge 211 and the second ink cartridge 212, and an ink storage member 22 is respectively installed in the two sunken arc surfaces.

[0054] In this embodiment, the first ink cartridge 211 and the second ink cartridge 212 are semi-cylindrical ink cartridges. A plurality of annular runway holes are respectively provided on the first ink cartridge 211 and the second ink cartridge 212, facilitating the ink on the first ink cartridge 211 and the second ink cartridge 212 to penetrate through the plurality of through holes onto the ink storage member 22.

[0055] Among them, the sizes of the plurality of annular runway holes on the first ink cartridge 211 and the second ink cartridge 212 may be different. The plurality of annular runway holes can be divided into multiple regions, and the sizes of the through holes in each region are different, so that different colors of ink can be added to the annular runway holes in each region, making the entire ink cartridge become multiple colors, that is, enabling the roller stamp in the embodiment of the present application to store multiple different colors of ink.

[0056] In this embodiment, on the outer circumferences of the first ink cartridge 211 and the second ink cartridge 212, that is, on the sides close to the stamp pad 23, a sunken arc surface is respectively provided, and the ink storage member 22 is embedded and installed in the sunken arc surface. The ink storage member 22 is specifically adhered in the sunken arc surface by hot melt adhesive, enabling the ink in the first ink cartridge 211 and the second ink cartridge 212 to better enter the ink storage member 22. Among them, the ink storage member 22 is specifically an ink storage pad in this embodiment.

[0057] Furthermore, the main body assembly 1 includes a housing 11. A limiting device 12 is connected to the housing 11, and the housing 11 is connected to the roller 21 through the limiting device 12, enabling the roller 21 to perform a limiting rotational movement relative to the housing 11 through the limiting device 12, so as to drive the roller 21 to rotate forward or backward relative to the housing 11.

[0058] In this embodiment, the main body assembly 1 includes a housing 11. A limiting device 12 is also provided on the housing 11. The housing 11 is connected to the roller 21 through the limiting device 12. When the roller 21 makes a circular motion relative to the housing 11, the limiting device 12 can drive the roller 21 to perform a limiting rotational movement relative to the housing 11, so that the roller 21 can rotate forward or backward relative to the housing 11.

[0059] Specifically, when the roller 21 starts to make a circular motion in the direction away from the housing 11, the roller 21 drives the content on the stamp pad 23 to be displayed from the back, that is, rotates forward relative to the housing 11, and when the entire pattern is completely printed, the limiting device 12 starts to move. When the roller 21 reaches the farthest point away from the housing 11, the stamp pad 12 leaves the surface of the object to be printed, and the limiting device 12 drives the roller 21 to rotate back, that is, rotate in the reverse direction relative to the housing 11. Among them, compared with the existing cylindrical small-sized stamp pad, when the roller 21 drives the stamp pad 23 to roll on the surface of the object to be printed in the embodiment of the present application, the unfolded stamp pad 23 is a large-sized rectangular stamp surface, which is convenient for each user to expose and produce stamps.

[0060] Among them, existing roller stamps are all infinitely circulating and rolling naturally without a limiting function. However, the roller stamp in the embodiment of the present application is provided with a limiting device 12, which has a limiting function and can perform rolling printing with a limited length, enabling the roller to move forward and automatically rotate relative to each other.

[0061] Further, a card slot is respectively provided on both sides of the housing 11. The card slot on one side of the housing 11 is also connected to the limiting device 12. A clamping member is respectively provided on both sides of the roller shaft 21. The clamping members on both sides of the roller shaft 21 are respectively clamped in the card slots on both sides of the housing 11 and are connected to the limiting device 12 in the card slots, so that the roller shaft 21 can perform a limiting rotary motion relative to the housing 11.

[0062] In this embodiment, a card slot is respectively provided on both sides of the housing 11, and a clamping member is respectively provided on both sides of the roller shaft 21. The shapes and sizes of the card slots on both sides of the housing 11 and the clamping members on both sides of the roller shaft 21 are adapted to each other, so that the housing 11 and the roller shaft 21 can be adaptively clamped through the card slots and clamping members on their both sides, and the roller shaft 21 can also perform a circular motion relative to the housing 11.

[0063] Among them, the limiting device 12 is connected in the card slot on one side of the housing 11. A clamping member on the roller shaft 21 is clamped in the card slot connected to the limiting device 12 and is connected to the limiting device 12 therein, so that the roller shaft 21 can perform a limiting rotary motion relative to the housing 11.

[0064] Further, the limiting device 12 includes a rotary member 121, a coil spring 122 and a limiting coupling 123. The rotary member 121 is clamped in the card slot of the housing 11, and the coil spring 122 is embedded in the rotary member. One end of the coil spring 122 is connected to the housing 11, and the other end is arranged on the limiting coupling 123. The limiting coupling 123 is connected to the clamping member of the roller shaft 21, so that the coil spring 122 drives the roller shaft 21 to rotate forward or reverse relative to the housing 11.

[0065] In this embodiment, the limiting device 12 includes a rotary member 121, a coil spring 122 and a limiting coupling 123. The rotary member 121 is clamped in the card slot of the housing 11. The coil spring 122 is embedded on the side of the rotary member 121 close to the card slot, and one end of the coil spring 122 is fixedly connected to the housing 11, and the other end is fixedly connected to the limiting coupling 123. The side of the limiting coupling 123 away from the rotary member 121 is connected to the clamping member of the roller shaft 21.

[0066] Specifically, when the roller 21 is pushed to roll forward from the starting point, that is, when the roller 21 rotates positively relative to the housing 11, the roller 21 drives the limit coupling 123 to drive the coil spring 122 to perform a circular motion together to start stamping. When the roller 21 runs to the end point, the limit coupling 123 starts to limit, the stamp pad 23 on the roller 21 leaves the surface of the object to be stamped, and the elastic force of the coil spring 122 will drive the limit coupling 123 to drive the roller 21 to rotate reversely relative to the housing 11, so as to return to the starting position.

[0067] Furthermore, the specific usage steps of the replaceable-surface roller stamp in the embodiment of the present application are as follows:

[0068] First, pull out the bottom cover 3 from the housing 11. The user holds the housing 11 and pushes the roller 21 to draw out multi-color, gradient-color, single-color patterns and characters. When the roller 21 rotates positively relative to the housing 11 from the starting point, the coil spring 122 drives the limit coupling 123 to drive the roller 21 to perform a circular motion to start stamping. When it runs to the end point, the limit coupling 123 starts to limit. The user no longer applies a forward pushing force to the housing 11, and the stamp pad 23 on the roller 21 leaves the surface of the object to be stamped. Under the elastic force of the coil spring 122, it will drive the roller 21 to rotate reversely relative to the housing 11 and return to the starting position to prepare for the next stamping process, and then cover the bottom cover 3.

[0069] When it is necessary to replace the stamp pad 23, first remove the first pressing member 213 and the second pressing member 214 pressed on the stamp pad 23, the first ink cartridge 211 and the second ink cartridge 212, and then remove both ends of the stamp pad 23 from the protrusions 4 on the first ink cartridge 211 and the second ink cartridge 212, and then the stamp pad 23 can be replaced.

[0070] When it is necessary to refill the first ink cartridge 211 and the second ink cartridge 212, only need to press the pressing member 2112 connected to the buckle groove on the first ink cartridge 211, so that the buckle member 2122 in the buckle groove can be snapped out of the buckle groove, and the first ink cartridge 211 and the second ink cartridge 212 can be opened at a certain angle, thus facilitating ink refilling.
