Abstract
Description
Technical Field
[0001] This invention relates to the field of numbering machine technology, and more specifically to a mechanical number carry device. Background Technology
[0002] Number printing offers certain anti-counterfeiting features. However, the emergence of new anti-counterfeiting technologies has placed new demands on numbering rollers. Existing numbering roller feeding devices use multiple cams inserted into the roller to drive each numberer individually, making it difficult to create a cavity in the roller structure. In some numbering processes, such as those requiring vacuum to adhere the printed material to the numbering roller, the existing roller structure is insufficient.
[0003] Therefore, how to provide a number roller that can form a vacuum cavity in the middle and enable normal number carry-over is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0004] In view of this, the present invention provides a mechanical number carry device for use in a roller-type coding machine. The numberer completes one carry per revolution of the roller. The carry is reliable and stable with a low failure rate. Furthermore, the roller can be designed as a vacuum roller.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mechanical number carry-in device, comprising: a mounting base, the mounting base being fixed on the outer peripheral side wall of a roller body, the mounting base being provided with a plurality of number device mounting positions spaced axially corresponding to the roller body, a number device being fixedly connected to each of the plurality of number device mounting positions, and a carry-in rocker arm being provided on the number device to drive its carry-in;
[0006] The number carry mechanism includes a transmission bar, a transition adapter, and a guide plate. The transmission bar is axially and reciprocally slidably connected to the mounting base corresponding to the roller body. Multiple sets of transition adapters are respectively connected to multiple number reader mounting positions, and the multiple sets of transition adapters are driven by the transmission bar below them. The transition adapter is hinged to the carry rocker on the corresponding side. The guide plate is located at one end of the transmission bar and is rotatably connected to the roller body. The guide plate is provided with a curved track groove. A rolling element is connected to the end of the transmission bar. The rolling element is slidably connected in the curved track groove. The rolling element slides in the curved track groove for one revolution, driving the transmission bar to reciprocate once. The reciprocating movement of the transmission bar completes the number reader carry.
[0007] The beneficial effects of this invention are as follows: The numbering device utilizes a number carry mechanism to complete mechanical carry. The carry rocker arm of the numbering device is connected to a transition adapter. During the reciprocating movement of the transmission bar, the transition adapter drives the carry rocker arm to rotate reciprocally, completing the carry of the numbering device. Utilizing the relative rotational relationship between the guide plate and the roller body, the guide plate is relatively fixed in position. As the printing roller body rotates, due to the sliding connection between the rolling element at the end of the transmission bar and the curved groove on the guide plate, the rolling element makes axial movement during rotation within the annular curved groove. During this movement, it drives the axial extension and contraction of the transmission bar. Each complete swing of the numbering device completes one advance, advancing the number by one position. The carry is reliable, the structure is simple, and it is easy to use, making it suitable for the need for simultaneous printing of multiple numbers on large-format paper.
[0008] Preferably, the mounting base is provided with a groove corresponding to the axial direction of the roller body, and the transmission bar is reciprocally slidably connected in the groove.
[0009] The resulting technical effect is that the reciprocating movement of the transmission bar on the mounting base is more stable and safer.
[0010] Preferably, a swing arm is connected between the carry rocker and the transition adapter, one end of the swing arm is hinged to the transition adapter, and the other end of the swing arm is hinged to the carry rocker of the corresponding numberer.
[0011] The resulting technical effect is that the power transmission is facilitated by the lever, which has strong compatibility and makes it easy to transform the reciprocating movement of the transmission bar into the reciprocating rotation of the carry rocker, thereby realizing the carry of the numberer.
[0012] Preferably, the transition adapter is a gear structure or a slider structure. When the transition adapter is a gear structure, the gear is rotatably connected to the numbering device mounting position on a fixed axis, the transmission bar has teeth and meshes with the gear for transmission, and one end of the swing arm is hinged to one side wall of the gear. When the transition adapter is a slider structure, the slider is slidably connected to the numbering device mounting position, the transmission bar is connected to the corresponding slider and drives the slider to reciprocate, and one end of the swing arm is hinged to the slider.
[0013] The resulting technical effect is that the transition adapter has various structures and different transmission methods, all of which can realize the reciprocating movement of the transmission bar to drive the carry rocker to swing back and forth, thus completing the numbering device carry-in.
[0014] Preferably, the carry-in rocker is fixed to the central shaft end of the number generator, and the other end of the carry-in rocker near the swing arm is provided with a ball joint, and the other end of the swing arm is movably connected to the ball joint.
[0015] The resulting technical effect is that the carry-in rocker is connected to the central shaft, and the rotation of the central shaft completes the number wheel carry-in under the action of the ratchet mechanism. The carry-in rocker, the swing arm, and the transition connector form a multi-link mechanism to realize the reciprocating rotation of the carry-in rocker.
[0016] Preferably, a pad is provided between the number reader and the mounting base, and a transition adapter mounting seat is provided on the mounting base for each number reader mounting position. The transition adapter is adapted to the transition adapter mounting seat, and the transition adapter drives the swing arm to swing, and the swing arm drives the advance rocker to complete the number reader advance.
[0017] The resulting technical effect is that the pad allows the numbering device to be installed on the mounting base, and ensures that the installation height of the numbering device is higher than that of the transmission bar. The transition adapter and the transmission bar are adjusted to the appropriate position, and the advance rocker is connected to ensure the normal operation of the advance mechanism.
[0018] Preferably, the mounting base is provided with limiting seats at both ends, and the roller body is provided with outer shoulders that cooperate with the limiting seats at both ends. The mounting base is provided in multiple sets and is arranged circumferentially at intervals on the outer side wall of the roller body.
[0019] The resulting technical effect is that the cooperation between the outer shoulder and the limiting seat enables the mounting base to be fixedly installed on the roller body. Multiple mounting bases are provided on the outer surface of the roller body, which is suitable for printing large-format numbers.
[0020] Preferably, the guide disc is connected to the guide disc fixing seat with an adjustable axial angle, and the end of the roller body is provided with a shaft head, and the guide disc is connected to the shaft head through a bearing.
[0021] The resulting technical effect is that the installation position of the guide plate is relatively fixed, and the rotation of the roller body will not drive the guide plate to rotate, ensuring that the transmission bar can reciprocate under the action of the rolling body and the curved track.
[0022] Preferably, the curved groove on the guide plate corresponds to the axial back-and-forth movement of the roller body, and the rolling element is slidably connected in the curved groove and drives the transmission bar to reciprocate in the groove.
[0023] By adjusting the positional relationship between the guide disc and the guide disc fixing seat, and realizing the axial tilt angle between the guide disc and the roller body, the undulation amplitude of the curved track is changed, the axial movement of the transmission bar is adjusted, and thus the number advance state is controlled.
[0024] The resulting technical effect is that one rotation of the roller body corresponds to one reciprocating movement of the transmission bar, thus completing one increment of the number reader. To stop the number increment, the guide plate can be offset from the axis of the roller body by a certain angle using an adjusting mechanism. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0033] See the appendix of this invention. Figures 1 to 6 According to an embodiment of the present invention, a mechanical number carry device includes:
[0034] Mounting base 1 is fixed on the outer peripheral side wall of roller body 2. Mounting base 1 is provided with a sliding groove corresponding to the axial direction of roller body 2. Mounting base 1 is provided with multiple numberer mounting positions at intervals corresponding to the axial direction of roller body 2. Numberers 3 are fixedly connected to each of the multiple numberer mounting positions.
[0035] The number carry mechanism 4 includes a transmission bar 41, a transition connector 42 (gear), a rocker arm 43, and a guide plate 44. The transmission bar 41 is slidably connected in a groove. There are multiple sets of gears, each fixedly rotatably connected to multiple numberer mounting positions. The multiple gears mesh with the transmission bar 41. One end of the rocker arm 43 is hinged to one side wall of the gear, and the other end of the rocker arm 43 is hinged to the carry rocker arm 5 of the corresponding numberer 3. The guide plate 44 is located at one end of the roller body 2, and the roller body 2 and the guide plate 44 rotate relative to each other. The position of the guide plate is fixed. The roller body rotates, and the guide plate 44 is provided with a curved track groove 441. The end of the transmission bar 41 is connected to a rolling element 45, which is slidably connected in the curved track groove 441. The rolling element 45 slides once in the curved track groove, causing the transmission bar 41 to reciprocate once in the groove. The reciprocating movement of the transmission bar 41 causes the gear, rocker arm, and carry rocker arm to work together to complete the numberer carry.
[0036] In other embodiments, the transition adapter is a slider structure, the slider is slidably connected to the numberer mounting position, the transmission bar 41 is connected to the corresponding slider and drives the slider to move back and forth, and one end of the rocker arm 43 is hinged to the slider. This transmission process can also realize the reciprocating movement of the transmission bar to drive the reciprocating rotation of the carry rocker arm.
[0037] In other embodiments, the carry-in rocker arm 5 is fixed to the central shaft end of the number generator 3. The other end of the carry-in rocker arm 5 near the swing arm 43 is provided with a ball joint 6. The other end of the swing arm 43 is movably connected to the ball joint 6. The swing arm, the carry-in rocker arm, the gear, and the slider are all hinged. The reciprocating rotation of the carry-in rocker arm realizes the number wheel carry-in.
[0038] In some other specific embodiments, a pad 7 is provided between the number reader 3 and the mounting base 1. The pad can increase the installation height of the number reader, making the number reader higher than the transmission bar, thus ensuring the smooth operation of the advance mechanism. A transition adapter mounting seat is provided on the mounting base 1 for each number reader mounting position. The transition adapter 42 is rotatably connected to the transition adapter mounting seat. The transition adapter 42 drives the swing rod 43 to swing, and the swing rod 43 drives the advance rocker 5 to complete the advance of the number reader.
[0039] In some other embodiments, the mounting base 1 has limiting seats 8 at both ends, and the roller body 2 has outer shoulders 14 at both ends that mate with the limiting seats 8. Multiple sets of mounting bases 1 are arranged circumferentially on the outer side wall of the roller body 2. The outer shoulders of the roller body enable a fixed connection between the multiple mounting bases 1.
[0040] In some other specific embodiments, the guide disk 44 is fixed on the guide disk fixing seat 9, and the end of the roller body 2 is provided with a shaft head 10. The guide disk 44 is connected to the shaft head 10 through the bearing 11. The roller body and the guide disk rotate relative to each other. The position of the guide disk is fixed, and the roller body rotates.
[0041] In some other embodiments, the curved groove 441 on the guide plate 44 corresponds to the axial back-and-forth movement of the roller body 2. The rolling element 45 is slidably connected in the curved groove 441 and drives the transmission bar 41 to move back and forth in the groove. When the roller body rotates once, the transmission bar and the swing rod swing once, and the number advances by one position.
[0042] The positional relationship between the guide disc 44 and the guide disc fixing seat 9 is changed by three adjusting parts 15, and the axial angle of the guide disc 44 is adjusted. Since the guide disc 44 is connected to the shaft head 10 by ball bearing, the tilt angle of the guide disc 44 can be adjusted, thereby changing the undulation amplitude of the curved track groove 441, adjusting the axial movement of the transmission bar 41, and thus controlling whether the number is carried over.
[0043] The adjusting element 15 can be a miniature cylinder that can be automatically controlled to change the tilt angle between the guide plate and the roller body.
[0044] This invention relates to the continuous shifting of the number in the serial number header during the printing process of a roller-type serial numbering machine. Roller-type serial numbering machines are used to meet the needs of printing large-format, multi-number serial numbers. The serial number needs to advance by one position after each printing cycle. This invention uses mechanical shifting, has a simple structure, and is reliable in operation.
