Description

Technical Field

[0001] The invention belongs to the technical field of numbering machines, and in particular relates to an electric number carrying device. Background Art

[0002] Number printing has a certain anti-counterfeiting function. With the emergence of new anti-counterfeiting technology, new requirements have been put forward for number rollers. The existing number roller feed device consists of multiple cam pieces inserted into the roller, which drive each number device on the roller respectively. Its roller 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 product on the number roller, the existing roller structure is difficult to achieve.

[0003] In addition, the numbering device on the existing roller structure is easily affected by the roller when the number is advanced, resulting in printing errors, which will affect the accuracy of the printed product.

[0004] Therefore, how to provide a number roller that can form a vacuum cavity in the middle and can achieve normal number advancement is a problem that those skilled in the art urgently need to solve. Summary of the invention

[0005] In view of this, the present invention provides an electric number carry device, which is used in a drum-type code printer to complete the number carry. The carry is completed by an electrical device with a low failure rate. On this basis, the drum can be designed as a vacuum drum, which is conducive to the realization of a new anti-counterfeiting process.

[0006] In order to achieve the above object, the present invention adopts the following technical scheme: an electric number carry device, comprising:

[0007] A mounting base, the mounting base is a long strip structure, the mounting base is fixed on the outer wall of the drum body, the two ends of the mounting base extend to the two end edges of the drum body, and a plurality of mounting positions are provided on the mounting base corresponding to the axial direction of the drum body;

[0008] A numbering device, wherein the numbering devices are provided in plurality and are fixedly connected to the plurality of mounting positions in a one-to-one correspondence, and the numbering device contacts the printed product to print the code;

[0009] There are multiple motors, each of which is fixed on each of the multiple mounting positions. The output shaft of the motor is drivingly connected to the input end of the spindle of the numbering device.

[0010] The driver comprises multiple groups and is connected to the multiple installation positions one by one. Each driver is connected to the motor electrical signal of the corresponding side. The multiple drivers are connected to the external controller by electrical signals. The driver controls the forward and reverse operation of the motor and completes the carry of the numbering device.

[0011] The beneficial effects of the present invention are as follows: The numbering device is connected to the drum body through the installation base. The installation base is provided with multiple installation positions, and a numbering device is installed on each installation position. The installation of the numbering device is flexible and convenient. The character wheel of the numbering device is controlled by a driver and a motor, and will not be affected by the rotation of the drum body, so the number jumping is accurate. The work of the numbering device is relatively independent and is only adjusted by the corresponding electrical signal. The structure and rotation process of the printing code drum do not affect the number carry, and the printing code is more accurate.

[0012] Preferably, a plurality of installation bases are circumferentially arranged at intervals on the outer side wall of the drum body. A plurality of numbering devices on each installation base form a group, and the plurality of numbering devices in each group are spaced on the same straight line.

[0013] The resulting technical effect is that a plurality of installation bases are installed on the drum body, and a plurality of numbering devices are arranged on each installation base, which is used for a drum-type printing code machine and is suitable for the working requirements of simultaneous printing of large-format multiple numbers.

[0014] Preferably, transition bases are provided on all the plurality of installation positions. A numbering device, a motor and a driver are installed on each transition base. A transmission gear is fixedly connected to the output shaft of the motor. A power transmission member is fixedly connected to the main shaft input end of the numbering device. The transmission gear is in transmission connection with the power transmission member, and the reciprocating rotation of the power transmission member causes the character wheel to rotate and complete the number carry.

[0015] The resulting technical effect is that each numbering device is an independent working unit. The transmission gear on the output shaft of the motor drives the power transmission member to move, and the power transmission member drives the main shaft of the numbering device to reciprocate. Under the action of the ratchet mechanism, the character wheel is controlled to complete the number carry.

[0016] Preferably, a wire box is fixedly installed on one side of the driver. A wire groove is provided on the installation base. The wire box is connected to an external controller by an electric wire, and the electric wire is located in the wire groove. The wire box is electrically connected to the driver.

[0017] The resulting technical effect is that the wire box is installed beside the carry mechanism. All the power supply wires of the same group of numbering devices extend to one end through the wire groove and are connected to the external controller. The motor and the driver obtain driving power and control electrical signals through the electric wires.

[0018] Preferably, the plurality of numbering devices work independently of each other.

[0019] The resulting technical effect is that each numbering device is an independent working unit, without interfering with each other, and different printing code requirements can be realized.

[0020] Preferably, fixing blocks are provided at both ends of the installation base, and the fixing blocks are fixedly connected to the outer shoulders at the ends of the drum body.

[0021] The resulting technical effect is that the connection between the mounting base and the drum body is realized by using the fixing block, and multiple mounting bases can be arranged on the outer surface of the drum body.

[0022] Preferably, the motor is a brushless reduction motor, and the driver is an electric driver. Description of the Drawings
