Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of article printing, in particular to a fixing device used for printing equipment. Background Art
[0002] Printing equipment refers to equipment that uses printing plates or printing rollers to print patterns or texts on the surface of objects to be printed. Since printing rollers can not only print on flat objects, but also on some raised or recessed objects, they are widely used.
[0003] In the prior art, printing equipment usually uses rollers to lift the objects to be printed, and then uses printing rollers to roll over the surface of the objects to achieve continuous printing of the objects. Although the printing speed is fast, when printing some thinner objects, such as plastic films, paper, etc., the printed part of the objects cannot be flattened, and wrinkles are prone to appear on the printed parts. When some additional straightening devices are used to straighten the objects, it is difficult to control the tension of the objects when straightening them, and the objects are easily damaged due to excessive tension.

DETAILED DESCRIPTION
[0021] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.
[0022] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 A fixing device for printing equipment is shown.
[0023] The first embodiment of the utility model refers to Figure 1 A fixing device for printing equipment includes a bottom plate 1, which provides an installation place for other components. The four corners of the upper surface of the bottom plate 1 are provided with installation holes 15, which are convenient for fixing the bottom plate 1 and the upper components on the installation position of the printing equipment. The upper part of the bottom plate 1 is provided with two left-right symmetrical guide seats 3 through a fixed support frame 2. The inside of the guide seats 3 is provided with a slide 4 for sliding. The front and rear ends of the guide seats 3 are provided with a slide 301. The middle of the upper and lower inner walls of the slide 301 are provided with a guide bar 302. The slide 4 is respectively provided with the guide bar 302 inside the slide 301 for sliding. A roller 5 is rotatably provided between the two corresponding slides 4 on the left and right. The roller 5 can slide inside the slide 301 along the guide bar 302 through the slide 4. The upper part of the bottom plate 1 is provided with a downward pressing structure through the lifting components provided on the left and right sides. The downward pressing structure and the roller 5 are provided correspondingly up and down. The objects to be printed can be fixed by the mutual extrusion of the downward pressing structure and the roller 5. As a preferred embodiment, Figure 2 , Figure 3 and Figure 4As shown, the lifting component includes an electric push rod 6 and a connecting plate 7. There are two electric push rods 6. The two electric push rods 6 are respectively arranged at the left and right ends of the middle of the upper surface of the bottom plate 1. The connecting plates 7 are respectively arranged at the top of the telescopic end of the electric push rod 6. The pressing structure includes a control plate 8 and a pressure roller 11. The control plate 8 is respectively arranged at the lower part of the connecting plate 7 by bolts. The front and rear ends of the control plate 8 are both hinged with a mounting seat 10 through a control arm 9. The pressure roller 11 is respectively rotatably arranged between the two corresponding mounting seats 10 on the left and right. The pressure roller 11 1 corresponds to the upper and lower positions of the roller 5, the mounting seat 10 is slidably connected with the corresponding slide seat 4 below through the guide assembly, the guide assembly includes a guide rod 12, the guide rod 12 is respectively arranged at the lower part of the mounting seat 10, the lower end of the guide rod 12 is respectively slidably connected with the guide hole opened at the outer end of the slide seat 4, and a baffle 13 is fixed at the bottom end of the guide rod 12. When the mounting seat 10 moves upward with the pressure roller 11, the guide rod 12 slides in the guide hole opened at the outer end of the slide seat 4, and the baffle 13 can prevent the guide rod 12 from sliding out of the guide hole.
[0024] When printing an object, the telescopic end of the electric push rod 6 is extended to lift the upper part, so that the control board 8 pulls up the mounting seat 10 through the control arm 9, thereby moving the pressure roller 11 upward, and the object to be printed passes through the gap between the support roller 5 and the pressure roller 11. Subsequently, the telescopic end of the electric push rod 6 is retracted to move the upper part downward, so that the pressure roller 11 is pressed on the top of the object to fix the object. In this process, the guide rod 12 slides in the guide hole opened at the outer end of the slide seat 4, and the angle of the opening of the two adjacent control arms 9 is The mounting seat 10 pushes the slide seat 4 to slide and adjust inside the slide opening 301 through the guide rod 12, thereby ensuring that the roller 5 and the pressure roller 11 always correspond to each other up and down during the movement of the mounting seat 10 with the pressure roller 11. After the pressure roller 11 and the roller 5 clamp the object, as the telescopic end of the electric push rod 6 contracts, the upper component moves downward, so that the pressure rollers 11 and the rollers 5 on the left and right sides straighten the object. At the same time, during the straightening process of the object, since the pressure roller 11 and the roller 5 can rotate freely, it is possible to avoid damage to the object due to excessive tension.
[0025] The second embodiment of the utility model refers to Figure 2 As shown, when printing an object, the printing roller of the printing device presses on the surface of the object, which easily causes deformation of the pressed position of the object. Preferably, a support roller 14 is rotatably arranged in the middle between the two guide seats 3.
[0026] When printing an object, the object is first clamped and stretched by the pressure roller 11 and the support roller 5 to flatten the printing position of the object, and then the surface of the object is printed by the printing roller of the printing equipment. The support roller 14 can support the middle part of the object. During the printing operation, the printing roller and the support roller 14 are pressed against the object in correspondence with each other up and down to avoid the situation where the pressure of the printing roller causes the object to be deformed, thereby improving the printing quality.
[0027] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The various components mentioned in the utility model are common technologies in the existing field. The technicians in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
