Description

Technical Field

[0001] The present invention relates to the technical field of numbering machines, and particularly relates to a mechanical number carry device. Background Art

[0002] Number printing has certain anti-counterfeiting functions. With the emergence of new anti-counterfeiting processes, new requirements are also put forward for number drums. The existing number drum carry device inserts multiple cam plates into the drum and drives each numberer on the drum respectively. Its drum structure is not easy to form a cavity. In some number printing processes, such as when it is necessary to use vacuum to adsorb the printed matter on the number drum, the existing drum structure is difficult to achieve.

[0003] Therefore, how to provide a number drum that can form a vacuum cavity in the middle and can achieve normal number carry is an urgent problem 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, which is used in a drum-type coding machine. When the drum body rotates one week, the numberer completes one carry. The carry is reliable and stable, and the failure rate is low. And on this basis, the drum can be designed as a vacuum drum.

[0005] In order to achieve the above object, the present invention adopts the following technical solution: A mechanical number carry device, which includes a mounting base fixed on the outer peripheral side wall of the drum body. Multiple numberer mounting positions are axially spaced on the mounting base corresponding to the drum body. Numberers are fixedly connected to all of the multiple numberer mounting positions. A carry rocker for driving its carry is provided on the numberer.

[0006] A number carry mechanism, the number carry mechanism includes a transmission bar, a transition adapter and a guide disk. The transmission bar is slidably connected to and fro axially corresponding to the drum body on the mounting base. There are multiple groups of the transition adapters, which are respectively connected to multiple numberer mounting positions. Multiple groups of the transition adapters are in transmission connection with the transmission bar below them. The transition adapter is hinged to the carry rocker on the corresponding side. The guide disk is located at one end of the transmission bar and is rotatably connected to the drum body. A curve track groove is provided on the guide disk. A rolling body is connected to the end of the transmission bar. The rolling body is slidably connected in the curve track groove. The rolling body slides one week in the curve track groove to drive the transmission bar to move to and fro once. The to-and-fro movement of the transmission bar completes the carry of the numberer.

[0007] The beneficial effects of the present invention are as follows: The numbering device uses a number-carrying mechanism to complete mechanical carry. The carry rocker 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 to rotate reciprocally, completing the carry of the numbering device. Utilizing the relative rotation relationship between the guide disk and the drum body, with the position of the guide disk relatively fixed, during the rotation process of the printing code drum body, due to the sliding connection relationship between the rolling body at the end of the transmission bar and the curved rail groove on the guide disk, the rolling body makes an axial crosstalk during the rotation in the annular curved rail groove. During the crosstalk process, it drives the axial expansion and contraction of the transmission bar. Each time a swing is completed, the numbering device completes one advancement, and the number advances by one digit. The carry is reliable, the structure is simple, and it is convenient to use, meeting the requirements for large-format multi-number simultaneous printing code.

[0008] Preferably, a chute is axially provided on the mounting base corresponding to the drum body, and the transmission bar is reciprocally slidably connected in the chute.

[0009] The resulting technical effect is that the reciprocating movement of the transmission bar on the mounting base is more stable and safe.

[0010] Preferably, a swing rod is connected between the carry rocker and the transition adapter. One end of the swing rod is hinged to the transition adapter, and the other end of the swing rod is hinged to the carry rocker of the corresponding side of the numbering device.

[0011] The resulting technical effect is that the swing rod is used to transfer the driving force, with strong compatibility, facilitating the transformation of the reciprocating movement of the transmission bar into the reciprocating rotation of the carry rocker, thereby realizing the carry of the numbering device.

[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 installation position in a fixed-axis manner. There are teeth on the transmission bar and it meshes with the gear for transmission. One end of the swing rod 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 installation position. The transmission bar is connected to the corresponding slider and drives the slider to reciprocate. One end of the swing rod 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 driving the carry rocker to swing reciprocally, completing the carry of the numbering device.

[0014] Preferably, the carry rocker is fixed at the end of the central axis of the numbering device. A ball joint is provided at the other end of the carry rocker close to the swing rod, and the other end of the swing rod is movably connected to the ball joint.

[0015] The resulting technical effect is that the carry rocker is connected to the central axis, and the rotation of the central axis completes the wheel carry under the action of the ratchet mechanism. The carry rocker, the swing rod, and the transition adapter form a multi-link mechanism to realize the reciprocating rotation of the carry rocker.

[0016] Preferably, a spacer is provided between the numbering device and the mounting base. A transition adapter mounting seat is provided on the mounting base corresponding to each numbering device mounting position. The transition adapter is adaptively connected to the transition adapter mounting seat. The transition adapter drives the swing rod to swing, and the swing rod drives the carry rocker to complete the carry of the numbering device.

[0017] The resulting technical effect is that the spacer realizes the installation of the numbering device and the mounting base, and ensures that the installation height of the numbering device is higher than the transmission strip. The transition adapter and the transmission strip are adjusted to a suitable position and connected to the carry rocker to ensure the normal operation of the carry mechanism.

[0018] Preferably, limiting seats are provided at both ends of the mounting base. Outer shoulders that cooperate with the limiting seats are provided at both ends of the drum body. There are multiple groups of mounting bases and they are circumferentially arranged at intervals on the outer side wall of the drum body.

[0019] The resulting technical effect is that the cooperation between the outer shoulder and the limiting seat realizes the fixed installation of the mounting base and the drum body. Multiple mounting bases are provided on the outer surface of the drum body, meeting the printing code requirements for large format and multiple numbers.

[0020] Preferably, the guide disk is connected to the guide disk fixing seat with an adjustable axial angle. A shaft head is provided at the end of the drum body. The guide disk is connected to the shaft head through a bearing.

[0021] The resulting technical effect is that the installation position of the guide disk is relatively fixed, and the rotation of the drum body will not drive the guide disk to rotate, ensuring that the transmission strip realizes reciprocating movement under the action of the rolling body and the curved rail groove.

[0022] Preferably, the curved rail groove on the guide disk undulates axially before and after corresponding to the drum body. The rolling body is slidably connected in the curved rail groove and drives the transmission strip to reciprocate in the chute.

[0023] By adjusting the position relationship between the guide disk and the guide disk fixing seat through the adjusting member and realizing the axial inclination angle between the guide disk and the drum body, the undulation amplitude of the curved rail groove is changed, the axial movement of the transmission strip is adjusted, and then the carry state of the number is controlled.

[0024] The resulting technical effect is that when the drum body rotates one week, the reciprocating movement of the transmission strip is realized once, and then one carry of the numbering device is completed. When it is necessary to stop the number carry, the guide disk and the axis of the drum body can be misaligned by a certain angle using the adjusting member. Description of the Drawings
