Description

The positioning structure of the plastic hose printing machine

technical field

The utility model relates to a printing device, in particular to a positioning structure of a plastic hose printing machine.

Background technique

Tube packaging is the most commonly used packaging method for daily necessities, because the tube packaging has the advantages of light weight and easy portability. The production of general tube containers such as toothpaste tubes, shampoo tubes, etc., is after the tube container is integrally formed, and then the tube container is printed on the surface of the tube body by a printing device before it can enter the market as a container device. .

At present, there are five main printing processes for hoses:

1. Gravure printing:

Plate material: Generally, an offset plate (a stick-shaped metal plate) is used as the bottom of the printing plate.

Process: Transfer printing is adopted. First, the ink is printed on the offset plate (or stick-shaped metal plate); secondly, the ink pattern on the offset plate (or stick-shaped metal plate) is transferred to the leather cloth (carrier); then the leather cloth ( The ink pattern on the carrier) is transferred to the product; finally, the ink is dried by static electricity, baking or light curing.

Advantages: There are many options for printing graphics and accuracy.

Disadvantages: Transferring ink graphics must be transferred through one carrier, which is easy to increase overprint deviation and render variegated colors.

2. Flexographic printing:

Plate: generally use offset (or stick metal plate) as the bottom of the printing plate.

Process: Printing by direct printing, first printing the ink on the offset plate (or stick gold

metal plate); secondly, dip the ink graphic on the offset plate (or stick metal plate) and print it directly on the product; then use standing, baking or light curing to dry the ink and complete.

Advantages: Printing graphics, fineness, and variety; transfer ink graphics to directly print products, reducing overprint deviation and rendering noise caused by multiple transfers through one carrier.

3. Screen printing:

Plates: Generally, the mesh is tensioned on the frame of hard materials (such as aluminum, iron, wood),

as a printed version.

Process: Printing by direct printing, first put the ink upside down on the patterned mesh; secondly use a soft scraper to scrape the ink onto the product according to the pattern of the mesh; finally use standing, baking or light curing Dry the ink and it's done.

Advantages: Printed graphics have a three-dimensional sense and a clear sense of touch; colors and vividness are substantial.

Four, bronzing printing:

Plate: generally use hard metal (such as aluminum alloy, copper alloy material) coating (or not coating)

Soft glue as a printing plate.

Process: Printing by direct hot stamping, first heat the hot stamping plate; secondly use the heated plate, and emboss the special film paper on the product; finally, the film paper is attached to the product after embossing to complete.

Advantages: Hot stamping with various high-brightness and glitter-like film papers, the graphics are full of metallic feeling, and the colors are bright and vivid.

5. Roller printing:

Plates: generally do not use plates.

Process: Use the roller method to roll printing directly. First, the liquid state such as ink or varnish is applied

Material, use the roller to roll the paint on the product in a large area; secondly, dry the oil by standing, baking or light curing to complete.

Advantages: Large-area products can be completed with simple processes.

It can be seen that various printing processes have their corresponding advantages and disadvantages. Different products have different requirements for printing and can choose the printing process they need. Even some products require multiple printing processes to complete. The printing equipment is also different. For products that require multiple printing processes, there will inevitably be intermediate material transfer and feeding processes in the production of different equipment, which not only prolongs the process, but also increases the difficulty of positioning in the second printing; and currently In the current printing equipment, the feeding mechanism with multiple hose mandrels only relies on one motor for positioning and rotation, and the hoses on each mandrel are identified by printing positioning marks and using the electric eye switch on the equipment, so the positioning accuracy is limited. For products that require multiple printing processes, there will inevitably be printing errors, which will affect the printing quality of the product.

Utility model content

The purpose of the utility model is to provide a positioning structure for a plastic hose printing machine, which can effectively reduce positioning errors in printing and improve the printing quality of products.

For achieving the above object, the solution of the present utility model is:

A positioning structure of a plastic hose printing machine, the printing machine mainly includes a machine body base, an advancing and retreating pipe device, a feeding device, a printing device and a drying device; the feeding device includes a rotating disc and a mandrel mechanism distributed on the rotating disc; Among them: each mandrel mechanism includes a mandrel, a mandrel fixing seat, a mandrel motor fixing seat and a mandrel motor group, the mandrel is positioned in the mandrel fixing seat and driven by the mandrel motor group, and the mandrel motor group is fixed on the mandrel motor On the seat, the mandrel motor fixing seat is fixed on the rotating disk through the mandrel fixing seat, and each mandrel protrudes outside the rotating disk.

After adopting the above scheme, since each mandrel of the feeding device of the printing machine of the utility model is controlled and positioned by the mandrel motor group, the positioning accuracy of the hose in various printing processes can be guaranteed, and the positioning in printing can be effectively reduced. error, improve the printing quality of the product.

Detailed ways

As shown in Figures 1 to 4, the utility model discloses a positioning structure of a plastic hose printing machine, which includes a body base 1, an advancing and retreating pipe device 2, a feeding device 3, a printing device 4 and a drying device 5.

Described feeding device 3 comprises a rotating disk 31 and the mandrel mechanism 32 that is distributed on the rotating disk 31, each mandrel mechanism 32 is to be radially distributed on the rotating disk 31; Described each mandrel mechanism 32 comprises a mandrel 321, a mandrel Fixing seat 322, a mandrel motor fixing seat 323 and a mandrel motor group 324, the mandrel 321 is positioned in the mandrel fixing seat 322 and driven by the mandrel motor group 324, and the mandrel motor group 324 is fixed on the mandrel motor fixing seat 323, The mandrel motor fixing seat 323 is fixed on the rotating disk 31 through the mandrel fixing seat 322 , and each mandrel 321 protrudes from the rotating disk 31 .

The body base 1 is a disc base, on which a host drive control assembly 11 is longitudinally arranged. The host drive control assembly 11 mainly includes a host motor to drive a main shaft to rotate, and the top of the main shaft is connected to the rotating disc of the feeding device 3 31: On the base 1 of the machine body, there are fixed shafts 12 distributed around the center of the transmission control assembly 11 of the main engine.

The advancing and retreating pipe device 2 is arranged on one side of the body base 1 and aligned with the feeding device 3, and the upper part thereof is controlled by a motor to feed the pipe feeding manipulator and the pipe withdrawing manipulator to complete the advancing and retreating action of the hose.

The printing device 4 and the drying device 5 are movably fixed at the fixed axis 12 of the base 1 of the machine body, and are just aligned with the position of the mandrel 321 of the feeding device 3 .
