Detailed Description
In order to better understand the technical content of the invention, specific embodiments are provided below, and the invention is further described with reference to the accompanying drawings.
Referring to fig. 1-2, a plastic products surface pattern printing machine, including printing area 1, drive printing takes 1 pivoted actuating mechanism 2 and the conveyer belt 3 that drives plastic products and remove, conveyer belt 3 is located the below of printing area 1, actuating mechanism 2 includes director 4 and running roller 5, 1 wound mobius ring in printing area, printing area 1 is around on the running roller 5, the drive of running roller 5 printing area 1 rotates, be equipped with between the running roller 5 and carry the director 4 of formation mobius ring that the printing area 1 upper portion overturned with it, 3 tops of conveyer belt be equipped with the paint roller 6 of the laminating of 1 lower part top surface in printing area, printing area 1 is equipped with and constitutes the printing pattern by a plurality of first arch 7.
Plastic products are placed on the conveyor belt 3, and the conveyor belt 3 conveys the plastic products to the bottom of the printing belt 1 while rotating. The printing area 1 is around on the running roller 5, and running roller 5 drives printing area 1 when rotating and rotates, and printing area 1 is equipped with and constitutes the printing pattern by a plurality of first archs 7, 3 tops of conveyer belt be equipped with the paint roller 6 of 1 lower part top surface laminating of printing area, be stained with paint on the paint roller 6, paint roller 6 scribbles paint on the arch of printing area 1. The coating roller 6 is arranged on the top surface of the lower part of the printing belt 1, and the coating penetrates downwards under the action of gravity, so that the coating is favorably coated on the printing belt 1. Under the condition that paint on the printing belt 1 is excessive sometimes, because the printing belt 1 is wound into a Mobius ring, and a guide 4 which is used for forming the Mobius ring and used for clamping the upper part of the printing belt 1 and turning the printing belt 1 is arranged between the rollers 5, the guide 4 improves the rotation stability of the printing belt 1, the paint can flow onto the printing belt 1 from the end part to the root part of the first bulge 7 when the printing belt 1 is positioned below the printing belt 1, and along with the rotation of the printing belt 1, the paint flows downwards under the action of gravity when the printing belt 1 rotates to the inclined upward position of the printing belt 1, falls on the back surface of a printing surface when the paint flows downwards, is received by the paint roller 6 again on one hand, on the other hand, the paint can be prevented from directly flowing onto a plastic product to be printed, and the phenomenon that a large amount of redundant paint flows onto the end part of the first bulge 7 to cause ink. Because the printing belt 1 is wound into a Mobius ring, a plurality of first bulges 7 on the printing belt 1 can form a printing pattern with larger length, and the printable pattern is doubled under the condition of the printing belt 1 with the same length.
Specifically, the printing belt 1 comprises a flexible belt 8 and traction belts 9 which are arranged on two sides of the flexible belt 8 and provided with positioning holes 10, the traction belts 9 are higher than the surface of the flexible belt 8 and lower than the first protrusions 7, and two ends of the roller 5 are arranged on second protrusions 11 inserted into the positioning holes 10.
The printing belt 1 comprises a flexible belt 8 and traction belts 9 which are arranged on two sides of the flexible belt 8 and provided with positioning holes 10, the traction belts 9 are higher than the surface of the flexible belt 8 and lower than the height of the first protrusions 7, and two ends of the roller 5 are arranged on second protrusions 11 inserted into the positioning holes 10.

The clamping wheel 12 is rotatably arranged on the U-shaped clamp 13, the U-shaped clamp 13 has elasticity, the printing belt 1 is clamped from two sides, and the printing belt 1 is stabilized, so that the printing belt 1 is stable in the rotating process. The clamping wheels 12 are in multiple groups, and clamp the printing belt 1 at different positions, so that the rotation stability of the printing belt 1 is ensured.
Specifically, the paint roller 6 is installed below a lifting platform 15, the lifting platform 15 is connected with a rack 14 through a spring 16, and the paint roller 6 presses the plastic product on the conveying belt 3. The lifting platform 15 is pushed downwards under the action of the spring 16, so that the lifting platform 15 moves downwards for a certain distance, the paint roller 6 presses the printing belt 1, on one hand, the first bulge 7 of the printing belt 1 can be attached to a printing surface, and on the other hand, the paint roller 6 can be attached to the printing belt 1. When the spring 16 pushes the lifting table 15 to move downwards to the bottommost position, the coating roller 6 pushes the printing belt 1 downwards to a height which is not enough for the non-convex part of the printing belt 1 to contact with the printing surface. Optionally, the lifting platform 15 is slidably connected to the support.
Specifically, a storage box 17 is arranged above the paint roller 6, paint is filled in the storage box 17, and a strip-shaped discharging groove 18 attached to the upper surface of the paint roller 6 is formed in the bottom of the storage box 17. The reservoir 17 contains liquid paint which flows out of a discharge chute in the bottom of the reservoir 17 onto the surface of the paint roller 6, the paint roller 6 being rotated to apply paint to the first protrusions 7.
Specifically, a support plate 19 is arranged below the upper part of the conveyor belt 3. Avoid conveyer belt 3 to sink, improve the stability of printing.
Specifically, the linear speed of the rotation of the printing belt 1 is the same as the linear speed of the rotation of the conveying belt 3. Alternatively, the roller 5 is driven by the motor 20 to rotate, and the roller 5 drives the roller of the conveyer belt 3 to rotate through the belt transmission mechanism 21.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
