Description

Technical Field

[0001] This utility model belongs to the field of stamping machine technology, and in particular to an ink cartridge mechanism used in stamping machines. Background Technology

[0002] A seal is a stationery item used to mark documents for authentication or signature. Generally, seals are first dipped in ink before being stamped. There are also seals that do not need to be dipped in ink and are stamped directly on a flat surface to create an embossed mark, which are called steel seals. In addition, there are wax seals that are stamped on wax or sealing wax, or wax seals on envelopes.

[0003] With the development of the seal industry, manual stamping has gradually been replaced by automated mechanical stamping. Stamping machines can replace manual stamping and are widely used as office equipment.

[0004] Chinese patent document CN113478991A discloses an ink return mechanism and a stamp device. The ink return mechanism includes a bracket and a sleeve slidably fitted on the bracket. A stamp clamp for holding the stamp is provided inside the bracket, and the stamp clamp is fixedly connected to the sleeve. One end of the bracket forms a stamping area. The orthographic projection of the stamp surface held by the stamp clamp is located within the stamping area. A cover for abutting and covering the stamp surface is also provided inside the bracket. The cover is rotatably connected to the bracket and the sleeve via a support shaft. Pushing the sleeve to slide towards the stamping area causes the cover to rotate with the support shaft, exposing the stamp surface. The stamp moves linearly to the stamping area of ​​the bracket for stamping operation.

[0005] In the above technical solution, the support in the ink return mechanism is also provided with a cover for abutting and covering the stamp surface. The cover is rotatably connected to the support and sleeve through a pivot. Ink is applied to the cover. However, due to the setting and installation connection method of the cover, the stamp surface will be unclear.

[0006] Therefore, it is necessary to develop a new ink cartridge mechanism that allows the ink to adhere more closely to the stamp surface, making the stamping process clearer. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide an ink cartridge mechanism that makes the ink adhere more closely to the stamp surface, making the stamping clearer.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: one side of the ink cartridge mechanism is provided with a flip-connecting structure, so that the ink cartridge mechanism can be flipped to the side of the stamp movement channel; the ink cartridge mechanism has at least one other side provided with a detachable connecting structure.

[0009] The flip-up connection structure allows the ink cartridge mechanism to be flipped to the side of the stamp movement channel, enabling the stamp to move in a fixed direction. This structurally minimizes the size of the stamping machine, eliminating the need for additional space for stamp flipping. In particular, the ink cartridge mechanism has at least one other side with a detachable connection structure. This detachable connection is not a rigid or fixed connection, but rather a type of connection that can be broken by external force, such as a snap-fit, hook, mortise and tenon joint, or magnetism. This connection structure provides an opportunity for the ink to adhere closely to the stamp surface, allowing the stamp surface to pick up more ink. It is important to note that the ink cartridge mechanism has at least one other side with a detachable connection structure, meaning that at least one of the three sides of the ink cartridge mechanism is connected to the outside (stamping machine housing) via a detachable connection structure such as a snap-fit, hook, mortise and tenon joint, or magnetism.

[0010] Based on this detachable connection, the ink cartridge mechanism provides a certain amount of resistance to the stamp, allowing the stamp surface to be coated with ink. However, this resistance is not too great, and the force that causes the stamp to move can break this connection resistance. Furthermore, a flip-connection structure is provided on one side of the ink cartridge mechanism, which causes the force that causes the stamp to move to push the ink cartridge mechanism to flip to the side of the stamp movement channel. The ink cartridge mechanism does not obstruct the stamp from moving in a fixed direction.

[0011] Preferably, the ink cartridge mechanism includes an ink cartridge and a baffle, wherein the ink cartridge is detachably fitted together with the baffle; a flip shaft is provided on the baffle, and the flip shaft is part of the flip connection structure.

[0012] The ink cartridge is detachably fitted with the baffle, and can be disassembled and replaced when the ink cartridge needs to be replaced; by setting a flipping shaft on the baffle, the flipping connection structure is realized by shaft connection. When the ink cartridge mechanism is under force, it flips to the side of the stamp movement channel to give way to the stamp.

[0013] Preferably, the baffle has a bottom plate, and a first side plate and a second side plate extend upward from both sides of the bottom plate; a first groove and a second groove are respectively provided on the first side plate and the second side plate, and correspondingly, a first protrusion and a second protrusion are respectively provided on both sides of the ink cartridge.

[0014] The first protrusion of the ink cartridge engages with the first groove on the first side plate, and the second protrusion engages with the second groove, making it easier to assemble or disassemble the ink cartridge with the baffle. Furthermore, with the first and second side plates on both sides of the base plate blocking the ink cartridge, it will not easily fall off after being assembled with the baffle.

[0015] Preferably, the height of the first side plate and the second side plate is the same as the height of the ink cartridge; so that the ink cartridge and the baffle are more integrated after assembly.

[0016] Preferably, the ink cartridge mechanism further includes a self-locking structure, which has a latch and a locking groove; the latch is disposed on the ink cartridge, and the locking groove is disposed on the baffle, and the latch and the locking groove are fitted together to complete the self-locking.

[0017] The self-locking structure formed by the latch and locking groove makes the ink cartridge and the baffle more secure after they are assembled, and the ink cartridge will not fall off when the user shakes or swings it.

[0018] Preferably, the lock groove includes an upper lock groove piece and a lower lock groove piece, and the lock opening formed by the upper lock groove piece and the lower lock groove piece is narrower than the lock latch slide of the lock groove.

[0019] The lock opening is narrower than the latch slide. This structural design allows the latch to have a certain range of movement after entering the lock slot, but the narrow lock opening prevents it from being easily unlocked.

[0020] Preferably, a slide elastic element is provided at the end of the first slide or the second slide; the slide elastic element is used to be compressed inward by the ink cartridge when the self-locking structure is self-locked, and to eject the ink cartridge outward when the self-locking structure is unlocked.

[0021] Preferably, a hook is provided at the end of the baffle, and the hook cooperates with the rod; the flipping shaft is located below the hook.

[0022] The support rod holds the hook, so that when the stamping machine performs the stamping action, the baffle returns to its initial position, protecting the stamp.

[0023] Preferably, the ink cartridge is provided with a connecting block one, and the ink cartridge mechanism is also provided with a connecting block two that cooperates with the connecting block one; the connecting block one and the connecting block two constitute the disconnectable connection structure.

[0024] Preferably, both the first connecting block and the second connecting block are magnets. The inventors have found that magnets are a better disconnectable connection method than buckles, hooks, and mortise and tenon joints, as they do not cause physical damage to the components and have an extremely low error rate.

[0025] Preferably, the base plate has an oil filling hole, and the bottom of the ink box is provided with an oil inlet hole; after the ink box and the baffle are assembled, the oil filling hole and the oil inlet hole are stacked together.

[0026] The base plate has an ink filling hole, which allows ink to be added even when the stamp is protected. Attached Figure Description

Detailed Implementation

[0036] As attached Figures 1-3As shown, the stamping machine 1 of this embodiment includes a locking mechanism 2, a stamp sleeve 3, and an ink cartridge mechanism 4, as well as an outer sleeve 5. An ink cartridge 6 is provided inside the outer sleeve 5, and the stamp 302 in the stamp sleeve 3 can reciprocate within the ink cartridge 6. The locking mechanism 2, the stamp sleeve 3, and the ink cartridge mechanism 4 are all located inside the outer sleeve 5 and are arranged sequentially along the extending direction of the ink cartridge 6. The ink cartridge mechanism 4 is disposed on the transverse section of the ink cartridge 6. Figure 2 As shown;

[0037] like Figures 4.0-4.3 As shown, one side 406 of the ink cartridge mechanism 4 is provided with a flip-up connection structure, which allows the ink cartridge mechanism 4 to be flipped to the side of the stamp movement channel 6; the ink cartridge mechanism 4 also has at least one other side 407 provided with a detachable connection structure.

[0038] In this embodiment, the ink cartridge mechanism 4 is flipped and connected to the outer sleeve 5 via a flipping shaft 408, allowing the ink cartridge mechanism 4 to be flipped to the side of the stamp movement channel 6. The ink cartridge mechanism 4 has at least one other side 407 that is disconnected from the outer sleeve 5 via a magnetic connection between magnets. When the stamp 302 in the stamp sleeve 3 moves downwards along the stamp movement channel 6 to stamp, it takes ink. After taking ink, as the stamp 302 continues to move downwards, the disconnectable connection between the side 407 of the ink cartridge mechanism 4 and the outer sleeve 5 can be broken, pushing the ink cartridge mechanism 4 to flip to the side of the stamp movement channel 6, thus making room for the stamp 302 to stamp downwards.

[0039] The ink cartridge mechanism 4 includes an ink cartridge 401 and a baffle 402, such as Figure 4.0 As shown, the ink cartridge 401 is detachably fitted together with the baffle 402; a flip shaft 408 is provided on the baffle 402, the flip shaft 408 is part of the flip connection structure, and the ink cartridge mechanism 4 is flipped to the side of the stamp movement channel 6 through the flip shaft 408.

[0040] baffle 402 has a base plate 40201, such as Figure 4.1 As shown, a first side plate 40202 and a second side plate 40203 extend upward from both sides of the base plate 40201; a first sliding groove 40204 (located opposite to the second sliding groove 40205) is respectively provided on the first side plate 40202 and the second side plate 40203. Figure 4.1 (Only showing the position) and the second groove 40205, correspondingly, a first protrusion 40101 and a second protrusion 40102 (located on the opposite side of the first protrusion 40101) are respectively provided on both sides of the ink cartridge 401, such as Figure 4.3 As shown.

[0041] It should be noted that the height of the first side plate 40202 and the second side plate 40203 is the same as the height of the ink box 401.

[0042] exist Figure 4.1 Furthermore, it can be seen that the ink cartridge mechanism 4 also includes a self-locking structure 403, which has a latch 40301 and a locking groove 40302. The latch 40301 is disposed on the ink cartridge 401, and the locking groove 40302 is disposed on the baffle 402. The latch 40301 and the locking groove 40302 are fitted together to complete the self-locking.

[0043] The lock groove 40302 includes an upper lock groove piece 40303 and a lower lock groove piece 40304. The lock opening 40305 formed by the upper lock groove piece 40303 and the lower lock groove piece 40304 is narrower than the locking slide plate 40306 of the lock groove 40302.

[0044] A slide elastic element 404 is provided at the end of the first slide 40204 or the second slide 40205; the slide elastic element 404 (a spring is used in this embodiment) is used to be compressed inward by the ink cartridge 401 when the self-locking structure 403 is locked, and to pop the ink cartridge 401 outward when the self-locking structure 403 is unlocked.

[0045] When the baffle 402 needs to be fitted with the ink cartridge 401, the first protrusion 40101 is embedded in the first slide groove 40204, and the second protrusion 40102 is embedded in the second slide groove 40205. Continuous pushing compresses the slide groove elastic element 404. The latch 40301 enters the locking groove 40302 through the locking opening 40305 and is positioned on the latch sliding plate 40306. Removing the pushing force causes the slide groove elastic element 404 to provide elastic restoring force to the ink cartridge 401, pushing the ink cartridge 401 outwards. Since the locking opening 40305 is narrower than the latch sliding plate 40306 of the locking groove 40302, the latch 40102... When 301 is pressed down by the lower locking groove 40304 and embedded in the locking groove 40302, the baffle 402 and the ink cartridge 401 can be assembled. During disassembly and assembly, the compression of the sliding groove elastic element 404 causes the latch 40301 to move downwards from the upper locking groove 40303. The sliding groove elastic element 404 will generate a pushing force that pushes the ink cartridge 401 outwards. At this time, with a little force, the latch 40301 can be lifted out along the upper locking groove 40303 towards the locking opening 40305. The latch 40301 embedded in the locking groove 40302 can then be disassembled from the locking groove 40302, thus realizing the disassembly of the baffle 402 and the ink cartridge 401.

[0046] A hook 405 is provided at the end of the baffle 402, and a support rod 301 is provided on the sleeve 3 (e.g., Figure 3As shown, the hook 405 cooperates with the rod 301; the flipping shaft 408 is located below the hook 405 and is mounted on the outer sleeve 5.

[0047] like Figure 2 As shown, the flip shaft 408 is fitted onto the outer casing 5; from Figure 3 It is evident that when the stamp sleeve 3 returns to its initial position, the support rod 301 on the stamp sleeve 3 supports the hook 405 of the baffle 402 upwards. The specific working principle is as follows: when the stamp 302 moves downwards along the stamp movement channel 6 in the stamp sleeve 3, the stamp 302 completes ink intake in the ink cartridge 401, simultaneously providing a pushing force to the ink cartridge mechanism 4, completely breaking the disconnectable connection between it and the outer sleeve 5. This causes the ink cartridge mechanism 4 to flip downwards based on the flipping shaft 408 (at this time, the support rod 301 disengages from the hook 405), and the ink cartridge mechanism 4 flips 90 degrees to the rightmost side of the stamp movement channel 6, clearing the path for the stamp 302 to move downwards. The stamping process ends when the stamp 302 moves upward along the stamp movement channel 6 in the stamp sleeve 3. The restoring force of the return structure 203 on the locking mechanism 2 pulls the stamp sleeve 3 back to its initial position. The ink cartridge mechanism 4 rotates upward based on the flipping shaft 408. At this time, the support rod 301 contacts the support hook 405 and pulls the ink cartridge mechanism 4 to rotate upward. The rotation of 90 degrees makes the ink cartridge mechanism 4 return to the transverse section position of the stamp movement channel 6, preventing the stamp 302 from being exposed. The ink return process is completed.

[0048] The ink cartridge 401 is provided with a connecting block 40103. The ink cartridge mechanism 4 is provided with a connecting block 40104 on the outer casing 5 (the housing of the stamping machine 1) that cooperates with the connecting block 40103. The connecting block 40103 and the connecting block 40104 constitute the detachable connection structure. The ink cartridge mechanism 4 achieves a detachable connection with the outer casing 5 through the connecting block 40103 and the connecting block 40104. Both the connecting block 40103 and the connecting block 40104 are magnets. Figure 4.0 In the middle, the connecting block 2 40104 on the right side is fitted onto the outer sleeve 5. The ink cartridge mechanism 4 and the outer sleeve 5 are connected together by the magnetic attraction between the connecting block 1 40103 and the connecting block 2 40104. When the external force (the pushing force of the stamp 302 in the stamp sleeve 3 moving downward along the stamp movement channel 6) exceeds the magnetic attraction, the two can be separated.

[0049] like Figure 4.2 , Figure 4.3 As shown, the base plate 40201 has an oil filling hole 40206, and the bottom of the ink cartridge 401 is provided with an ink inlet 40105; after the ink cartridge 401 and the baffle 402 are assembled, the oil filling hole 40206 and the ink inlet 40105 are stacked together. Figure 4.2 In the image, we can also see that the ink cartridge 401 has multiple interconnected oil channels 40106 at the location where the sponge is placed. These oil channels 40106 are all connected to the ink inlet 40105, which makes it easy for the stamp to pick up ink.

[0050] like Figure 2 As shown, the outer sleeve 5 includes a stamp tube 502 and a movable cover 501. The outer side of the outer sleeve 5 is provided with a movable cover 501 that can slide up and down. The movable cover 501 is used to drive the locking mechanism 2 to move vertically in the stamp movement channel 6. The stamp sleeve 3 and the locking mechanism 2 are connected together.

[0051] The control panel 7 is located inside the head unit 8 at the upper end of the outer casing 5; the head unit 8 is equipped with a camera 801 and an infrared receiver 802, such as... Figures 1-3 As shown.

[0052] The stamping machine in this embodiment uses the following steps to stamp:

[0053] S1: Set the stamping operation time to within S seconds;

[0054] S2: After receiving the stamping instruction, drive the stamp 302 to move downward along the stamp movement channel 6;

[0055] S3: After the stamp 302 takes ink, continue to drive the stamp 302 to move downward along the stamp movement channel 6 to the stamping piece;

[0056] S4: Complete a stamping within S seconds;

[0057] S5: Drive the stamp 302 to move upward along the stamp movement channel 6 to the initial position, and drive the ink cartridge mechanism 4 to return to the initial position, completing the ink return action.

[0058] In step S2, the seal 302 is in a locked state before receiving the stamping instruction.

[0059] Between step S4 and step S5, a closing instruction will be received.

[0060] It also includes step S6, in which, after receiving a stamp removal instruction, the stamp sleeve 3 disengages from the stamp locking mechanism 2 and moves downward along the stamp movement channel 6, pushing one side of the ink cartridge mechanism 4 to disconnect from the outer sleeve 5, and exiting the outer sleeve 5 to complete one stamp removal.

[0061] In step S6, after the stamp 302 in the stamp sleeve 3 is replaced, the stamp sleeve 3 moves upward along the stamp movement channel 6 and connects with the locking mechanism 2, thereby driving the ink box mechanism 4 to connect with the outer sleeve 5 (the connection can be disconnected, that is, the connecting block 1 40103 and the connecting block 2 40104 are magnetically connected together).

[0062] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
