Description

Technical Field

[0001] The utility model belongs to the technical field of printing and gilding machines, and particularly relates to a stepping drive device for a printing and gilding machine. Background Art

[0002] The gilding process is a special printing process without ink. The so-called gilding refers to the process of hot stamping an aluminum foil onto the surface of a printing substrate under certain temperature and pressure. A gilding machine is the equipment for completing the gilding process. The stepping drive device of a printing and gilding machine is mostly a roller conveyor.

[0003] At present, the drive decoration of a gilding machine relies on fixedly connecting the output shaft of a rotating motor coaxially with one of the guide rollers. Baffles are fixedly connected to both ends of the guide roller in the length direction. The baffles are vertically arranged, and the length direction of the baffles is the same as the conveying direction of the guide roller.

[0004] Since the above-mentioned technology uses a fixed baffle to prevent the materials conveyed on the guide roller from shifting, when the printing and gilding machine needs to print materials of different specifications, the baffle at this time cannot be adjusted correspondingly according to the size of the materials, it is difficult to effectively limit the sides of the materials, and the applicable range is relatively narrow. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a stepping drive device for a printing and gilding machine, which has the advantage of being able to adjust the blocking specification according to the size of the material, and solves the problem that the baffle of the existing roller conveyor is difficult to make adaptive adjustment according to the size of the material, and the applicable range is relatively narrow.

[0006] To achieve the above purpose of being able to adjust the blocking specification according to the size of the material, the utility model provides the following technical solutions:

[0007] The stepping drive device of a printing and gilding machine includes: a roller conveyor; a guiding mechanism, which is installed on the surface of the roller conveyor; a spacing adjusting mechanism, which is installed on the surface of the guiding mechanism.

[0008] As a preferred solution of the stepping drive device of the printing and gilding machine of the utility model: the guiding mechanism includes two mounting frames and two baffles. Both of the two baffles are slidably connected to the upper ends of the two mounting frames. The lower ends of the baffles are in non-pressure contact with the roller conveyor. The two baffles are symmetrically distributed on both sides of the center point of the mounting frame. A chute is opened at the upper end of one side of the mounting frame. The spacing adjusting mechanism includes a bidirectional lead screw rotatably connected to the inner wall of the chute. Threaded sleeves slidably connected to the chute are threadedly connected to the surfaces of the two opposite external threads of the bidirectional lead screw. The upper end of the threaded sleeve is fixedly connected to the adjacent baffle.

[0009] As a preferred embodiment of the stepper drive device of the printing and gilding machine of the present utility model: the horizontal cross-sectional shape of the baffle is arched, and the arched openings of the two baffles are opposite to each other.

[0010] As a preferred embodiment of the stepper drive device of the printing and gilding machine of the present utility model: the guiding mechanism further includes an electric cylinder, the output shaft of the electric cylinder is fixedly connected with a U-shaped connecting frame, and the two ends of the U-shaped connecting frame are respectively fixedly connected with the two mounting frames.

[0011] As a preferred embodiment of the stepper drive device of the printing and gilding machine of the present utility model: one end of the two-way lead screw away from the baffle penetrates to the outside of the mounting frame, and a turning handle is fixedly connected to the end of the two-way lead screw away from the mounting frame.

[0012] As a preferred embodiment of the stepper drive device of the printing and gilding machine of the present utility model: evenly distributed scales are engraved on the upper end of the mounting frame, and an indicating arrow aligned with the adjacent scale is fixedly connected to the end of the thread sleeve close to the turning handle away from the electric cylinder.

[0013] As a preferred embodiment of the stepper drive device of the printing and gilding machine of the present utility model: a protective plate is fixedly connected to the inner wall of one side of the chute close to the turning handle, the end of the protective plate away from the turning handle sequentially penetrates through the two thread sleeves and is fixedly connected to the inner wall of the side of the chute away from the turning handle, and the protective plate is arranged above the two-way lead screw.

[0014] Compared with the prior art, the present utility model provides a stepper drive device for a printing and gilding machine, which has the following beneficial effects:

[0015] The staff can quickly adjust the distance between the two baffles through the two-way lead screw. Compared with the existing fixed baffles, this can meet the limiting and guiding requirements of different sizes of materials, so as to expand the overall applicable range of the device. At the same time, the staff can adjust the two baffles simultaneously and centrally, which not only improves the efficiency of the staff in adjusting the baffles, but also can reduce the probability of triggering between the guided and conveyed materials and the printing mechanism of the printing and gilding machine, so as to improve the printing accuracy of the printing mechanism of the printing and gilding machine for the materials.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1 - Figure 4 For a technical solution provided by the present utility model:

[0023] The step driving device of the printing and gilding machine includes: a roller conveyor 1; a guiding mechanism 2, the guiding mechanism 2 is installed on the surface of the roller conveyor 1; a spacing adjusting mechanism 3, the spacing adjusting mechanism 3 is installed on the surface of the guiding mechanism 2;

[0024] The roller conveyor 1 and the guiding mechanism 2 are fixedly connected to the inside of the printing and gilding machine, both ends of the guiding mechanism 2 penetrate to the outside of the printing and gilding machine, and the spacing adjusting mechanism 3 is arranged on the outside of the printing and gilding machine.

[0025] As shown in Figure 1 、 Figure 2 and Figure 3 , the guiding mechanism 2 includes two mounting frames 23 and two baffles 24. The two baffles 24 are both slidably connected to the upper ends of the two mounting frames 23. The lower ends of the baffles 24 are in non-pressure contact with the roller conveyor 1. The two baffles 24 are symmetrically distributed on both sides of the center point of the mounting frame 23; the horizontal cross-sectional shape of the baffle 24 is arched, and the arched openings of the two baffles 24 are opposite; the guiding mechanism 2 further includes an electric cylinder 21. The output shaft of the electric cylinder 21 is fixedly connected with a U-shaped connecting frame 22. The two ends of the U-shaped connecting frame 22 are respectively fixedly connected with the two mounting frames 23. Workers can adjust the real-time height of the baffle 24 by controlling the shortening or extension of the electric cylinder 21 to meet the guiding and positioning requirements of different heights;

[0026] After the staff place the material at the upper end of the roller conveyor 1, during the process of the roller conveyor 1 transporting the material, the two baffles 24 can guide the material towards the middle of the roller conveyor 1, so that the material can be just below or above the printing mechanism in the printing and gilding machine after being transported into the interior of the printing and gilding machine by the roller conveyor 1. And the baffle 24 can make the roller conveyor 1 transport the material vertically and smoothly, so as to ensure that the printing mechanism in the printing and gilding machine can gild and print the material stably and correctly.

[0027] As Figure 2 and Figure 3 shown, a chute 25 is opened at the upper end of one side mounting frame 23. The spacing adjustment mechanism 3 includes a bidirectional lead screw 31 rotatably connected to the inner wall of the chute 25. Threaded sleeves 32 slidably connected to the chute 25 are threadedly connected to the surfaces of the two opposite external threads of the bidirectional lead screw 31. The upper end of the threaded sleeve 32 is fixedly connected to the adjacent baffle 24; one end of the bidirectional lead screw 31 away from the baffle 24 penetrates to the outside of the mounting frame 23, and a turning handle 33 is fixedly connected to the end of the bidirectional lead screw 31 away from the mounting frame 23; evenly distributed scales 34 are engraved on the upper end of the mounting frame 23. An indicating arrow 35 aligned with the adjacent scale 34 is fixedly connected to the end of the threaded sleeve 32 close to the turning handle 33 and away from the electric cylinder 21. This enables the staff to accurately adjust the relative spacing between the two baffles 24, so as to reduce the adjustment difficulty of the staff; a protective plate 36 is fixedly connected to the inner wall of the chute 25 close to the turning handle 33. One end of the protective plate 36 away from the turning handle 33 sequentially penetrates through the two threaded sleeves 32 and is fixedly connected to the inner wall of the chute 25 away from the turning handle 33. The protective plate 36 is arranged above the bidirectional lead screw 31. This can reduce the dust, debris and other impurities from falling onto the surface of the bidirectional lead screw 31, so as to improve the smoothness of the bidirectional lead screw 31 in adjusting the threaded sleeve 32;

[0028] When the staff need to gild and print materials of different sizes, the staff only need to rotate the turning handle 33 in the corresponding direction. The turning handle 33 drives the bidirectional lead screw 31 to rotate. The bidirectional lead screw 31 drives the two threaded sleeves 32 to move towards each other or away from each other through the two opposite threads on the surface. The two threaded sleeves 32 drive the two baffles 24 to move towards each other or away from each other until the distance between the two baffles 24 is adjusted to the size value matching the material.

[0029] It should be noted that in the above description, the printing and gilding machine, the roller conveyor 1, and the electric cylinder 21 are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supply of the printing and gilding machine, the roller conveyor 1, and the electric cylinder 21 can be powered by an internal power supply or by mains power. The specific power supply method is selected according to the situation and will not be elaborated here.
