Description

Technical Field

[0001] This application belongs to the technical field of roller stamping equipment, and more specifically, relates to a horizontal automatic continuous adjustment device for a stamp. Background Technology

[0002] As a type of automated stamping equipment, fully automatic stamping machines have a considerable potential market. Currently, they are widely used in industries such as finance and postal services. However, the existing stamp positions are fixed and cannot be automatically adjusted according to different stamping positions.

[0003] For example, current A4 stamp modules can support continuous stamping of mainstream paper sizes such as A4, A5, and 1 / 3A4. However, since different papers require different stamping positions, most stamp machines can adjust the stamp interval and starting position in the paper output direction (vertical) through different settings. But the horizontal stamping position is fixed. When the position needs to be adjusted, it is usually done by replacing the entire stamp module with different stamping positions, or by changing the position of the stamp and ink cartridge. Both of these methods cause great inconvenience to equipment maintenance. Alternatively, multiple stamps and multiple ink filling positions can be set on the stamp shaft to meet the multiple stamping position requirements, but this also results in the reuse of stamps and ink cartridges (inking positions), causing waste and increasing costs.

[0004] Therefore, there is an urgent need for a seal lateral adjustment device that can solve the problem that current seals cannot be adjusted laterally. Summary of the Invention

[0005] The purpose of this application is to provide a seal horizontal automatic continuous adjustment device to solve the technical problem that seals cannot be horizontally adjusted in the prior art.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: A stamp horizontal automatic continuous adjustment device is provided, comprising: a left support, a right support, a paper feed roller, a paper feed drive, a stamp shaft, a stamp drive, a cam assembly, a stamp roller, an ink cartridge, a horizontal movement assembly, an elastic assembly, and a retainer assembly. The two ends of the paper feed roller are rotatably mounted on the left and right supports. The two ends of the stamp shaft are elastically rotatably mounted on the left and right supports via the elastic assembly. The stamp drive drives the paper feed roller to rotate, and the stamp drive drives the stamp shaft to rotate. The stamp roller is slidably mounted on the stamp shaft and rotates synchronously with it. The cam assembly is located at both ends of the paper feed roller and the stamp shaft and can drive the stamp roller to separate from or contact the paper feed roller. The horizontal movement assembly is located on the left and right supports. The ink cartridge is mounted on the horizontal movement assembly and moves horizontally synchronously with the stamp roller via the retainer assembly. The retainer assembly has a clearance fit with the stamp shaft.

[0007] In one embodiment, the stamp shaft is provided with a central elongated groove, and the roller stamp includes a stamp body, a clamping block and a fastening screw. The stamp body and the clamping block are respectively located on both sides of the stamp shaft. The fastening screw passes through the clamping block and the central elongated groove in sequence and is threadedly connected to the stamp body. The roller stamp is in clearance fit with the stamp shaft in the length direction of the fastening screw.

One side of each thrust bearing is connected to the first rubber roller, and the other side is connected to the corresponding thrust retainer.

[0010] In one embodiment, the cam assembly includes a one-way bearing, a push cam, and a cam bearing. The push cam is disposed at one end of the paper feed roller via the one-way bearing, and the cam bearing is disposed at one end of the stamp shaft and abuts against the push cam.

[0011] In one embodiment, the elastic component includes a fixed block, a movable block, and a spring. The fixed block is fixed to the left or right support, and the movable block is movably mounted on the fixed block by the spring. The movable block is provided with a ball bearing for mounting the stamp shaft, and the spring force drives the stamp shaft to contact the paper feed roller.

[0012] In one embodiment, the movable block is provided with a limiting part to restrict the upward distance of the movable block.

[0013] In one embodiment, the lateral movement assembly includes: a lateral base, a lateral drive motor, a lateral timing belt, an optical axis guide rod, and a guide rail. The two ends of the lateral base and the optical axis guide rod are respectively fixed to the left support and the right support. The lateral drive motor, the lateral timing belt, and the guide rail are disposed on the lateral base. The ink cartridge holder is slidably mounted on the guide rail and the optical axis guide rod and is fixedly connected to one of the lateral timing belts. The lateral drive motor drives the lateral timing belt to move, thereby synchronously driving the ink cartridge holder to move.

[0014] In one embodiment, an initial position sensor is provided on the left or right support, and a sensing plate is provided on the stamp shaft. When the sensing plate is sensed by the initial position sensor, the roller stamp is in the initial position.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0030] like Figures 1-4As shown, an automatic continuous horizontal adjustment device for a stamp according to an embodiment of this application will now be described. This automatic continuous horizontal adjustment device for a stamp includes: a mounting frame 1, a paper feeding module 2, a stamp module 3, a cam assembly 4, a horizontal movement assembly 5, and an elastic assembly 6. The mounting frame 1 includes a left support 11 and a right support 12 spaced apart, connected together by a central support. The paper feeding module 2 includes a paper feeding roller 21 and a paper feeding drive 22. The stamp module 3 includes a stamp shaft 31, a stamp drive 32, a stamp roller 33, an ink cartridge 34, and a retainer assembly 36.

[0031] The paper feed roller 21 is rotatably mounted on the left support 11 and the right support 12 at both ends, and the stamp shaft 31 is elastically mounted on the left support 11 and the right support 12 at both ends via the elastic component 6. The paper feed roller 21 and the stamp shaft 31 are used to transport paper. The paper feed drive 22 drives the paper feed roller to rotate, and the stamp drive 32 drives the stamp shaft 31 to rotate. Both the paper feed drive 22 and the stamp drive assembly 32 use a motor combined with pulleys and a synchronous belt to drive the rotation of the paper feed roller and the stamp shaft 31. The purpose of this arrangement is to make the motor and the paper feed roller 21 or the stamp shaft 31 parallel to each other, reducing the axial length space.

[0032] The roller stamp 33 is slidably mounted on the stamp shaft 31 and rotates synchronously with the stamp shaft 31. The roller stamp 33 slides on the stamp shaft 31 to adjust the lateral position of the roller stamp 33. The roller stamp 33 rotates synchronously with the stamp shaft 31 to perform roller stamping on the paper. The cam assembly 4 is located at both ends of the paper feed roller 21 and the stamp shaft 31 and can drive the roller stamp 33 to separate from or contact the paper feed roller 21. The cam assembly 4 has a highest position and a lowest position. When the cam assembly 4 is in the lowest position, the elastic component 6 drives the roller stamp 33 to contact the paper feed roller 21, which can realize the stamping action. When the cam assembly 4 is in the highest position, the stamp shaft 31 moves, causing the roller stamp 33 to separate from the paper feed roller 21. There is a gap between the roller stamp 33 and the paper feed roller 21. At this time, the roller stamp 33 can be adjusted laterally on the stamp shaft 31. Specifically, the lateral movement component 5 is located on the left support 11 and the right support 12. The ink cartridge 34 is mounted on the lateral movement component 5 and moves laterally synchronously with the roller stamp 33 through the retainer assembly 36. The retainer assembly 36 is clearance-fitted with the stamp shaft 31. The lateral movement component 5 can realize the synchronous lateral position adjustment of the roller stamp 33 and the ink cartridge 34.

[0033] The device can adjust the lateral position of the roller stamp 33 to be suitable for stamping paper of different sizes; and the device only requires one roller stamp 33 and one ink cartridge 34, which solves the problem of redundant assembly of stamps and ink cartridges in the prior art.

[0034] In this embodiment, as Figures 1-3 As shown, the stamp shaft 31 is provided with a central long groove 311. The roller stamp 33 includes a stamp body 331, a clamping block 332, and a fastening screw 333. The stamp body 331 is roughly a semi-circular structure. The stamp is provided on the semi-circular arc surface of the stamp body 331. The plane of the stamp body 331 and the clamping block 332 are located on both sides of the stamp shaft 31, respectively. The fastening screw 333 passes through the clamping block 332 and the central long groove 311 in sequence and is threadedly connected to the stamp body 331. There are two clamping blocks 332 and two fastening screws 333. The fastening screw 333 not only fixes the roller stamp 33 on the stamp shaft 31, but also realizes the lateral movement of the roller stamp 33 on the stamp shaft 31 by cooperating with the central long groove 311. The roller stamp 33 is clearance-fitted with the stamp shaft 31 along the length of the fastening screw 333, allowing the stamp shaft 31 to move vertically relative to the fastening screw 333 within a range of 0.5-1mm. This also facilitates the lateral movement of the roller stamp 33. To achieve synchronous movement between the roller stamp 33 and the stamp shaft 31, first rubber rollers 334 are mounted on both ends of the roller stamp 33 via bearings. The first rubber rollers 334 can rotate freely relative to the roller stamp 33. Second rubber rollers 312 are fixed on both ends of the stamp shaft 31 via bearings. The second rubber rollers 312 can rotate freely relative to the stamp shaft 31. The outer diameters of the first rubber rollers 334, second rubber rollers 312, and roller stamp 33 are the same. During stamping, both the first rubber rollers 334 and second rubber rollers 312 roll in contact with the paper feed roller 21. During lateral adjustment, both the first rubber rollers 334 and second rubber rollers 312 separate from the paper feed roller 21.

[0035] In this embodiment, the retainer assembly 36 includes two thrust bearings 361 and two thrust retainers 362. The lateral movement assembly 5 is provided with an ink cartridge holder 35, which can move laterally left and right under the drive of the lateral movement assembly 5. One end of each of the two thrust retainers 362 is respectively set at both ends of the ink cartridge holder 34 by screws, and the other end is set at both ends of the roller stamp 33. The two thrust retainers 362 are fitted with the stamp shaft 31 with a gap, and the thrust bearings 361 are fitted with the stamp shaft 31 with a gap. One side of each thrust bearing 361 is connected to the first rubber roller 334, and the other side is connected to the corresponding thrust retainer 362. The thrust bearing 361 connects the thrust retainer 362 and the roller stamp 33, allowing the roller stamp 33 to rotate freely relative to the thrust retainer 362. The stamp shaft 31 is clearance-fitted with the thrust retainer 362 and the thrust bearing 361, with a clearance of 0.5-1mm, ensuring that the vertical movement of the stamp shaft 31 is not affected. The thrust retainer 362, when moving with the ink cartridge holder 35, synchronously drives the roller stamp 33 to move laterally on the stamp shaft 31.

[0036] In this embodiment, the cam assembly 4 includes a one-way bearing 41, a push cam 42, and a cam bearing 43. The push cam 42 is disposed at one end of the paper feed roller 21 via the one-way bearing 41, and the cam bearing 43 is disposed at one end of the stamp shaft 31 and abuts against the push cam 42. The push cam 42 has a highest position and a lowest position, both located on a straight line. The function of the one-way bearing 41 is that when the paper feed roller rotates forward, the push cam 42 is stationary relative to the paper feed roller 21, and the push cam 42 is in the lowest position (initial position or reset position). The paper feed roller 21 and the stamp shaft 31 can be used to realize the paper feeding and stamping actions. When the paper feed roller 21 rotates in reverse, due to the limiting effect of the one-way bearing 41, the push cam 42 rotates synchronously with the paper feed roller 21. After the paper feed roller 21 rotates 180°, the push cam 42 reaches the highest position, the paper feed drive 22 stops working, and the paper feed roller 21 stops moving. During the process of reaching the highest position, the push cam 42 pushes the cam bearing 43 to move downward, and the cam bearing 43 drives the stamp shaft 31 downward. The first rubber roller 334, the second rubber roller 312, and the stamp 33 are separated from the paper feed roller by a gap of 0.5-1mm. At the same time, the elastic component 6 is compressed. The lateral movement component 5 starts working, driving the ink cartridge holder 35 to move laterally and simultaneously driving the stamp 33 to move until the target position is reached. The lateral movement component 5 stops working, and the paper feed drive component 22 drives the paper feed roller 21 to continue to reverse 180°, driving the push cam 42 back to the reset position, so that the first rubber roller 334, the second rubber roller 312 and the paper feed roller 21 roll and contact again. Thus, the lateral position adjustment of the stamp 33 is completed. When the paper feed roller 21 rotates forward, the next step of paper feeding and stamping can be performed.

[0037] In this embodiment, two cam assemblies 4 are provided and are located at both ends of the paper feed roller 21 and the stamp shaft 31, respectively.

[0038] like Figure 4As shown, two elastic components 6 are provided, one on the left support 11 and one on the right support 12. Specifically, the elastic component 6 includes a fixed block 61, a movable block 62, and a spring 63. The fixed block 61 is fixed to the left support 11 or the right support 12 by screws. After the fixed block 61 is installed on the left support 11 or the right support 12, there is a gap between the fixed block 61 and the left support 11 or the right support 12. The movable block 62 is movably installed on the fixed block 61 by the spring 63 and is located within the gap. The movable block 62 is provided with a ball bearing 64 for installing the stamp shaft 31, thus realizing the rolling installation of the stamp shaft 31. The spring 63 is used to realize the elastic installation of the stamp shaft 31. The elastic force of the spring 63 drives the stamp shaft 31 to move in the direction of contact with the paper feed roller 21. When the push cam 42 is in the highest position, it pushes the seal shaft 31 downward, and the spring 63 is compressed; when the push cam 42 is in the lowest position, the spring 63 drives the seal shaft 31 upward under its own elastic force.

[0039] In this embodiment, the movable block 62 is provided with a limiting part 621 that limits the rising distance of the movable block 62. When the limiting part 621 and the fixed block 61 are in contact, the stamp shaft 31 is at its highest position. At this time, the first rubber roller 334 and the second rubber roller 312 on the stamp shaft 31 are in contact with the paper feed roller.

[0040] In this embodiment, the lateral movement assembly 5 includes: a lateral base 51, a lateral drive motor 52, a lateral timing belt 53, an optical axis guide rod 54, and a guide rail 55. The two ends of the lateral base 51 and the optical axis guide rod 54 are respectively fixed to the left support 11 and the right support 12. The lateral drive motor 52, the lateral timing belt 53, and the guide rail 55 are mounted on the lateral base 51. The ink cartridge holder 35 is slidably mounted on the guide rail 55 and the optical axis guide rod 54 and fixedly connected to one end of the timing belt. The lateral timing belt 53 is mounted on the lateral base 51 via two spaced-apart timing pulleys. When the lateral drive motor 52 drives the lateral timing belt 53 to move, it synchronously drives the ink cartridge holder 35 to move. The optical axis guide rod 54 and the guide rail 55 both serve to guide the lateral movement of the ink cartridge holder 35.

[0041] In this embodiment, an initial position sensor 13 is provided on the left support 11 or the right support 12, and a sensing plate 14 is provided on the stamp shaft 31. When the sensing plate 14 is sensed by the initial position sensor 13, the roller stamp 33 is in the initial position. When the roller stamp 33 is in the initial position, it contacts the ink box 34 to replenish the ink.

[0042] In this embodiment, two position detection sensors are provided at intervals on the horizontal base 51 to sense the reset position and the maximum position of the ink cartridge 34. The two position detection sensors are used to detect the initial position and the farthest position of the horizontal adjustment of the ink cartridge 34. The position of the ink cartridge 34 between these two positions is determined by the step counting of the horizontal drive motor 52.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
