Description

Technical Field

[0001] This utility model belongs to the technical field of seal control equipment, and in particular relates to a seal control and adjustment device. Background Technology

[0002] A seal control device is a device that manages one or more seals. It works by placing seals, such as official seals, on the machine head inside the device through a seal holder. After the person stamping the seal approves it, the device can be controlled so that the drive component moves the selected seal to the outside of the device and the automatic pressing mechanism presses down on the selected seal to achieve automatic stamping.

[0003] For example, Chinese utility model patent CN204472157U discloses a printing control device, which includes a housing, a printing control device body disposed within the housing, and a printing tray disposed at the bottom front of the housing. A camera device matching the printing tray is disposed at the top of the housing. An external interface and a power switch matching the printing control device body are disposed on the side of the housing. The printing control device body includes a printing head and an ink pad disposed below the printing head. Furthermore, the printing head is a four-stamp printing head, and the ink pad is an electrically controlled pull-out ink pad. A protective cover is also provided on the housing. The beneficial effects of this utility model are: the device has a simple structure, is easy to operate, and can meet the needs of printing multiple stamps at once.

[0004] See Figure 10 , 11 As shown, the existing printing control instrument body 1 mainly includes a base plate 11, multiple support rods 111 vertically fixed on the upper surface of one side of the base plate 11, and a top plate 12 horizontally fixedly connected to the upper end of the support rods 111. A drive assembly 13 is provided on the top plate 12. The drive assembly 13 includes a drive motor 131 vertically fixedly connected to one side of the top plate 12, a main synchronous pulley 132 fixedly connected to the output shaft of the drive motor 131 below the top plate 12, a driven synchronous pulley 133 rotatably connected to the other side of the top plate 12, and a synchronous belt 134 meshing with the main synchronous pulley 132 and the driven synchronous pulley 133. A guide assembly 14 is provided on the top plate 12 along its length direction. The guide assembly 14 is an existing horizontally arranged guide rod structure. A slider 15 is slidably mounted on the guide rod 141 of the guide assembly 14. The slider 15 is fixed on the synchronous belt 134. A stamping assembly 16 is fixedly installed on the lower end surface of the slider 15. The stamping assembly 16 includes a machine head (not shown in the figure) fixed to the slider 15 and a protective shell 161 formed around the outside of the machine head, and also includes a pressing mechanism (not shown in the figure). A support plate 17 is horizontally fixed to the upper end of the base plate 11 outside the protective shell 161. The machine head and pressing mechanism are prior art, and can also be found in the aforementioned Chinese utility model patent with authorization announcement number CN204472157U.

[0005] When using the existing stamping control device, the document to be stamped is placed on the support plate 17, and the drive motor 131 drives the synchronous belt 134 to rotate, thereby driving the slider 15 and the stamping assembly 16 to move along the guide rod 141 towards the upper part of the support plate 17 to the designated position. Then, the pressing mechanism of the stamping assembly 16 drives the stamp set on the machine head to move downward, passing through the opening at the lower end of the protective shell 161 to meet the document to be stamped, thereby completing the stamping operation. Afterward, the pressing mechanism, the stamp, and the stamping assembly 16 return to the initial position, completing the entire stamping process.

[0006] The existing seal control device has the following technical problems when in use: When selecting the stamping position of the document to be stamped, the document to be stamped is usually placed on the support plate 17 first, and the camera installed on the top plate 12 scans the position of the document to be stamped. Then, the stamping mark is dragged to the designated position of the scanned document to be stamped in the operation interface, and then the driving component 13 drives the stamping component 16 to move to the designated position for stamping.

[0007] This results in complex operation, high design costs, and software development issues. Furthermore, the diversity of stamping positions—such as differences between the client and contractor, and the need to adjust document placement on support plate 17 for larger documents—leads to discrepancies between the preview image obtained via camera scanning and the actual stamping position. Consequently, the stamping position cannot be accurately determined before stamping. Moreover, existing stamp control devices lack manual adjustment for camera malfunctions or to accommodate different user preferences. Therefore, there is an urgent need to design a simple, easy-to-operate stamp control and adjustment device that allows for intuitive determination of the stamping position on documents to be stamped. Utility Model Content

[0008] To address the technical problems existing in the prior art, this application provides a stamp control and adjustment device that is simple in structure, easy to operate, and can intuitively determine the stamping position of the document to be stamped.

[0009] To achieve the above objectives, this utility model provides the following technical solution: A seal control and adjustment device includes a top plate, a drive motor fixedly connected to one side of the top plate, a main synchronous pulley fixedly connected to the output shaft of the drive motor, a driven synchronous pulley rotatably connected to the other side of the top plate, and a synchronous belt meshing with the main and driven synchronous pulleys. A driven block and an adjustment block, which are arranged internally and externally and fixedly connected, can slide back and forth along the length of the top plate through a linear module set on the top plate. An adjustment plate is fixedly connected to the adjustment block, and a side plate is fixedly connected to the top plate on one side of the adjustment block. A groove is formed on the side plate, and the adjustment plate can be slidably embedded in the groove and extend to the outside of the side plate. A baffle plate is fixedly connected to the inner end face of the adjustment block, and a clamping block is fixedly connected to the synchronous belt. A slotted photoelectric switch is fixedly connected to the clamping block. The baffle plate and the slotted photoelectric switch can move relative to each other, and the baffle plate can be embedded in the sensing groove of the slotted photoelectric switch. A crosshair laser that emits a crosshair laser is fixedly connected to the driven block.

[0010] Preferably, two sets of linear modules are respectively provided corresponding to the driven block and the adjusting block. Each set of linear modules includes two fixed blocks fixedly connected to the two sides of the lower end of the top plate, a slide rod fixedly embedded in the two fixed blocks along the length direction of the top plate, and a sliding sleeve slidably mounted on the slide rod. The two sliding sleeves are respectively fixedly embedded in the adjusting block and the driven block.

[0011] Preferably, a fixing through hole is provided on the fixing block, and a clamping through groove communicating with the fixing through hole is provided on one end face of the fixing block. The slide rod passes through the fixing through hole, and the fastening bolt passes through the fixing block below the clamping through groove and is threadedly connected to the fixing block above the clamping through groove, so as to fix the slide rod in the fixing through hole.

[0012] Preferably, the clamping block includes a clamping plate and a fixing plate fixedly connected to the clamping plate, a timing belt fixedly connected between the fixing plate and the clamping plate, and a slotted photoelectric switch fixedly connected to the lower end face of the clamping plate.

[0013] Preferably, a mounting bracket is fixedly connected to the inner side of the lower end of the driven block, and the crosshair laser is fixedly connected to the mounting bracket.

[0014] Preferably, the two ends of the connecting plate are fixedly connected to the upper end faces of the driven block and the adjusting block, respectively.

[0015] Preferably, when the adjustment plate is not moved and the shield is embedded in the sensing slot of the slotted photoelectric switch, the crosshair laser emitted by the crosshair laser is located directly above the selected stamp to be stamped in the stamping assembly.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a driven block and an adjusting block fixedly connected to each other on the inner and outer sides below the top plate, along with a crosshair laser mounted on the driven block and an adjusting plate mounted on the adjusting block. Moving the adjusting plate synchronously moves the adjusting block, driven block, and crosshair laser, allowing for intuitive positioning of the stamping position on the document placed on the support plate using the crosshair laser emitted by the laser. Furthermore, through the cooperation of a slotted photoelectric switch and a shielding plate, the selected stamp of the stamping assembly can automatically stop at the crosshair intersection (i.e., the stamping point) projected by the crosshair laser onto the document. Therefore, this invention features a simple structure, convenient operation, and allows for intuitive determination of the stamping position on the document. Attached Figure Description

[0031] See appendix Figure 10 , 11As shown, the existing printing control instrument structure, such as the existing printing control instrument body 1, mainly includes a base plate 11, multiple support rods 111 vertically fixed on the upper surface of one side of the base plate 11, a top plate 12 horizontally fixedly connected to the upper end of the support rods 111, a drive assembly 13 is provided on the top plate 12, the drive assembly 13 includes a drive motor 131 vertically fixedly connected to one side of the top plate 12, a main synchronous pulley 132 fixedly connected to the output shaft of the drive motor 131 below the top plate 12, a driven synchronous pulley 133 rotatably connected to the other side of the top plate 12, and a synchronous belt 134 meshing with the main synchronous pulley 132 and the driven synchronous pulley 133. A guide assembly 14 is provided on the top plate 12 along its length direction. The guide assembly 14 is an existing horizontally set sliding rod structure. A slider 15 is slidably mounted on the guide rod 141 of the guide assembly 14. The slider 15 is fixed on the synchronous belt 134. A stamping assembly 16 is fixedly installed on the lower end surface of the slider 15. The stamping assembly 16 includes a head (not shown) fixed to the slider 15 and a protective shell 161 formed around the outside of the head, and also includes a pressing mechanism (not shown). A support plate 17 is horizontally fixed to the upper end of the base plate 11 outside the protective shell 161.

[0032] See Figure 1 , 2 As shown, a seal control and adjustment device includes a top plate 12, a drive motor 131, a main synchronous pulley 132, a driven synchronous pulley 133, and a synchronous belt 134. It also includes an adjustment block 2, a linear module 3, a slotted photoelectric switch assembly 4, an adjustment plate 5, a crosshair laser emitting assembly 6, and a driven block 7.

[0033] See Figure 3 , 4 As shown, the driven block 7 and the adjusting block 2 are arranged internally and externally and fixedly connected. Specifically, the driven block 7 is located in the lower middle part of the top plate 12, and the adjusting block 2 is located on one side below the top plate 12. The two ends of the horizontally arranged connecting plate 21 are fixedly connected to the upper end surfaces of the driven block 7 and the adjusting block 2 by bolts. Thus, the driven block 7 and the adjusting block 2 can reciprocate synchronously along the linear module 3.

[0034] The linear module 3 is provided in two sets corresponding to the driven block 7 and the adjusting block 2. Specifically, each set of linear module 3 includes two fixed blocks 31 fixedly connected to the front and rear sides of the lower end of the top plate 12 by bolts, a slide rod 32 fixedly embedded in the two fixed blocks 31 along the length direction of the top plate 12, and a sliding sleeve 33 sliding on the slide rod 32. The two sliding sleeves 33 on the two sets of linear modules 3 are fixedly embedded in the adjusting block 2 and the driven block 7 respectively, that is, the adjusting block 2 and the driven block 7 can reciprocate synchronously along the length direction of the slide rod 32.

[0035] Furthermore, to facilitate the fixed installation of the slide rod 32 on the fixing block 31, a fixing through hole 311 is provided on the fixing block 31, and a clamping through groove 312 communicating with the fixing through hole 311 is provided on one end face of the fixing block 31. The slide rod 32 passes through the fixing through hole 311, and the fastening bolt 313 passes through the fixing block 31 below the clamping through groove 312 and is threadedly connected to the fixing block 312 above the clamping through groove 312. With the above structure, after tightening the fastening bolt 313, the slide rod 32 can be fixed in the fixing through hole 311. In addition, in order to improve the ease of installation and installation accuracy of the two sets of linear modules 3, the two fixing blocks 31 on the left and right sides are integrally formed and fixedly connected by a connecting block 34.

[0036] It should be noted that the structure of the linear module 3 can take many forms. For example, in other embodiments, the linear module 3 can be a linear guide rail structure, that is, the guide rail is fixedly installed on the lower end face of the top plate 12 along its length direction by bolts, and the guide block is fixedly installed on the adjusting block 2 and the driven block 7. The adjusting block 2 and the driven block 7 slide synchronously along the length direction of the guide rail.

[0037] See Figure 5 As shown, in order to move the adjusting block 2, an adjusting plate 5 is fixedly connected to the vertical end face of the adjusting block 2 by bolts. The adjusting plate 5 includes a connecting part 51 fixed to the vertical end face of the adjusting block 2, a bent part 52 horizontally fixedly connected to the connecting part 51 along the sliding direction of the adjusting block 2, and a moving part 53 fixedly connected to one end of the bent part 52 and horizontally arranged.

[0038] See Figure 7 , 9 As shown, a vertically arranged side plate 18 is bolted to the top plate 12 on one side of the adjusting block 2. A groove 181 is formed on the side plate 18 along the sliding direction of the adjusting plate 5. The adjusting plate 5 can be slidably embedded in the groove 181 and extends to the outside of the side plate 18. Of course, for the sake of overall structural aesthetics and the safety of the printing control instrument, see... Figure 5 As shown, in addition to the side plate 18, the existing printing control device is also provided with an outer shell 19, and the outer shell 19 is provided with a shell outlet 191 so that the stamping assembly 16 can move to the top of the support plate 17 through the shell outlet 191.

[0039] See Figure 6 As shown, the slotted photoelectric switch assembly 4 includes a shielding plate 41, a clamping block 42, and a slotted photoelectric switch 43.

[0040] The clamping block 42 is set on the synchronous belt 134. The clamping block 42 includes a clamping plate 421 and a fixing plate 422 fixedly connected to the clamping plate 421. The synchronous belt 134 is fixedly connected between the fixing plate 422 and the clamping plate 421. The slotted photoelectric switch 43 is fixedly connected to the lower end face of the clamping plate 421 by bolts. The sensing slot of the slotted photoelectric switch 43 is set towards the adjusting block 2.

[0041] The baffle plate 41 is L-shaped, with its vertical part fixedly connected to the inner vertical end face of the adjusting block 2, and its horizontal part embedded in the sensing slot of the slotted photoelectric switch 43 in its initial position. The baffle plate 41 and the slotted photoelectric switch can move relative to each other; that is, when the adjusting plate 5 is moved, the adjusting block 2 and the baffle plate 41 can be disengaged from the sensing slot of the slotted photoelectric switch 43. When the synchronous belt 134 rotates, it will move the slotted photoelectric switch 43 and can make the baffle plate 41, which has been moved, embed itself back into the sensing slot of the slotted photoelectric switch 43.

[0042] See Figure 3 , 4 As shown, the crosshair laser emitting assembly 6 includes a mounting bracket 61 and a crosshair laser 62 of existing structure. The crosshair laser 62 can be an existing laser pointer that can emit crosshairs.

[0043] Mounting bracket 61 is fixed to the lower end of driven block 7 by bolts. Mounting bracket 61 has an S-shaped structure. A crosshair laser 62 is fixedly mounted on the horizontal part of the lower end of mounting bracket 61. The crosshair laser emitted by crosshair laser 62 is projected onto the upper surface of support plate 17. The intersection of the crosshair laser emitted by crosshair laser 62 is the stamping point.

[0044] See Figure 8 As shown, it should be noted that the existing stamp control device can have multiple stamps installed inside the print head. After the desired stamp is selected, the print head will rotate the desired stamp to a position close to the center of the support plate 17, such as... Figure 4 For ease of description, the selected stamp 8 is represented by a stamp graphic, located inside the protective housing 161. To ensure that the crosshair laser emitted by the crosshair laser 62 intersects the support plate 17 at the stamping point, in this embodiment, in the initial position (before the adjustment plate 5 is moved), the crosshair laser 62 is positioned directly above the selected stamp 8. At this time, the shielding plate 41 is embedded in the sensing slot of the slotted photoelectric switch 43. When the adjustment plate 5 is moved to move the crosshair laser 62 above the support plate 17, the synchronous belt 134 moves the slotted photoelectric switch 43 and the stamping assembly 16 synchronously until the shielding plate 41 is once again embedded in the sensing slot of the slotted photoelectric switch 43. At this time, the crosshair laser 62 is still directly above the selected stamp 8. Therefore, after placing the document to be stamped on the support plate 17, the adjustment plate 5 is moved so that the intersection of the crosshair laser emitted by the crosshair laser 62 is projected onto the document to be stamped, which is the center when the stamp 8 is selected for stamping.

[0045] The working principle and process of this embodiment are as follows: Install each component according to the above instructions, place the document to be stamped on the support plate 17, and the operator pulls the lever 53 towards himself, thereby driving the adjusting block 2, the driven block 7, and the shielding plate 41 to move synchronously, so that the shielding plate 41 is disengaged from the sensing slot of the slotted photoelectric switch 43. At this time, the crosshair laser 62 is triggered to emit a crosshair laser, which is projected onto the document to be stamped. By adjusting the position of the document to be stamped or by continuing to pull the lever 5, the position to be stamped is made to coincide with the cross intersection of the crosshair laser, thus completing the determination of the position to be stamped. Afterwards, the operator can press the confirmation stamping button on the stamping control device. The drive motor 131 of the stamping control device drives the main synchronous wheel 132 to rotate, which in turn drives the synchronous belt 134 to rotate, thereby causing the stamping assembly 16 to move towards the document to be stamped. During the movement of the slotted photoelectric switch 43, the baffle plate 41 is re-embedded in the sensing slot of the slotted photoelectric switch 43. At this time, the drive motor 131 stops rotating, the cross laser 62 is located directly above the selected stamp 8, and the stamping point on the document to be stamped is located directly below the selected stamp 8. The pressing mechanism of the existing stamping control device presses down on the selected stamp 8, and the selected stamp 8 abuts against the document to be stamped, thereby completing the stamping operation. Afterwards, the pressing mechanism and the selected stamp 8 return to their original positions. After the stamping is completed, push the toggle part 53 to the initial position, thereby driving the adjustment block 2, the driven block 7, and the shielding plate 41 to move synchronously. The drive motor 131 of the stamping controller rotates in the opposite direction to drive the main synchronous wheel 132 to rotate in the opposite direction, which in turn drives the synchronous belt 134 to rotate in the opposite direction, thereby driving the stamping assembly 16 to move away from the document to be stamped, until the shielding plate 41 is re-embedded in the sensing slot of the slotted photoelectric switch 43. At this time, the crosshair laser 62 no longer emits crosshair laser.

[0046] It should be noted that all items not described in this application are existing technologies. The power supply methods of the electronic components involved in this utility model are all existing technologies. The connection methods and control principles of components such as the slotted photoelectric switch 43 and the cross laser 62 with existing controllers are all existing technologies and will not be described in detail here. As long as the above working process can be met, it is acceptable.
