Description

Technical Field

[0001] The utility model relates to the technical field of packaging coding, in particular to a pneumatic ink wheel online coding mechanism. Background Technique

[0002] After the product is bagged during the production process, it is necessary to print the production date on the surface of the bag. The date coding machines are generally ink jet printers, ribbon coding machines, thermal transfer coding machines, laser jet printers, etc. For the above-mentioned date coding similar products, they all have the problems of complex structure, long debugging time and high manufacturing cost. Content of the Utility Model

[0003] The purpose of the utility model is to provide a pneumatic ink wheel online coding mechanism to solve the problems put forward in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: a pneumatic ink wheel online coding mechanism, including a mounting seat, a rectangular notch extending inwards is arranged on the side of the mounting seat, horizontal and opposite pressing cylinders are respectively installed on both sides of the bottom surface of the mounting seat opposite to the rectangular notch, a pressing block is fixedly installed on the piston rod of the pressing cylinder, a character pellet is installed on the front side of one pressing block, and a rubber pad is installed on the front side of the other pressing block. A vertically upward sliding table cylinder is fixedly installed on the upper side of the mounting seat through an L-shaped bracket. The sliding table cylinder is located on the top side of the rectangular notch. The sliding table cylinder is provided with a sliding table on one side of the rectangular notch. A ring sleeve with a notch is installed on the bottom side of the sliding table, and a rotatable ink wheel is installed on the bottom side of the sliding table. The ink wheel is concentrically and clearance-fitted with the inner cavity of the ring sleeve, and the ink wheel is heated and melted to ink the character pellet.

[0005] Preferably, the ring sleeve and the ink wheel move up and down through the rectangular notch.

[0006] Preferably, two groups of long strip holes are arranged on the mounting seat, and the pressing cylinder is installed at the long strip holes with bolts and can adjust the position.

[0007] Compared with the prior art, the beneficial effect of the utility model is that the sliding table cylinder drives the ink wheel to move up and down to stick ink to the character pellet. When a packaging bag is sealed and enters between the two pressing blocks, the front and back are driven by the pressing cylinder to realize coding. The structure of this mechanism is simple, the manufacturing cost is low, and the debugging is simple. Brief Description of the Drawings

[0011] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0012] Please refer to Figure 1-2 , the present invention provides a technical solution: a pneumatic ink wheel online coding mechanism, including a mounting base 1. A rectangular notch 2 extending inward is provided on the side of the mounting base 1. Horizontal and opposite pressing cylinders 3 are respectively installed on the bottom surface of the mounting base 1 on both sides opposite to the rectangular notch 2. A counter-pressure block 4 is fixedly installed on the piston rod of the pressing cylinder 3. A character particle is installed on the front side of one counter-pressure block 4, and a rubber pad is installed on the front side of the other counter-pressure block 4. Two sets of long holes are provided on the mounting base 1. The pressing cylinder 3 is installed at the long holes with bolts and can adjust its position. After the two counter-pressure blocks 4 are pressed against each other, a date is printed at the sealing position ( Figure 2 The position indicated by A in

[0013] is the packaging bag).

[0014] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
