Patterns on the surface of the packaging box are complete, and the printing position precision of the patterns is high.

Description

Technical Field

[0001] The utility model relates to the technical field of color printing equipment, in particular to color printing equipment for producing packaging boxes. Background Art

[0002] After the packaging box is produced, a pattern needs to be printed on the surface of the packaging box to specifically represent the contents inside the packaging box. In the prior art, a packaging box color printer is used to print color on the surface of the packaging box, making the pattern on the surface of the packaging box more vivid and beautiful.

[0003] When the packaging box color printing machine is in use, the packaging box is placed on the top end surface of the packaging box color printing machine, and then the UV printing head is controlled by the control device to slide along the outer wall of the packaging box color printing machine, so that the UV printing head is driven to perform color printing operations on the surface of the packaging box. However, in this process, the position of the packaging box is easily offset, resulting in errors in the printing position of the pattern on the surface of the packaging box.

[0004] The main reason for the above problems is that when the UV print head slides along the outer wall of the packaging box color printing machine, the influence of the gravity of the UV print head will cause the packaging box color printing machine in contact with it to vibrate as a whole, and for the packaging box directly placed on the packaging box color printing machine, it will also be affected by the vibration, causing the packaging box in a relatively active state to move on the packaging box color printing machine, causing the overall position of the packaging box to shift. In addition, some packaging box color printing machines are equipped with a positioning plate to position the packaging box, but the positioning plate will offset the printing surface of the packaging box, causing the printing surface of the packaging box to be blocked, making the overall pattern of the packaging box incomplete, affecting the printing quality of the packaging box. To address the above problems, we propose a packaging box production color printing equipment. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a color printing device, which solves the problem that during the color printing process of the packaging box, the position of the packaging box is easily offset, resulting in an error in the printing position of the pattern on the surface of the packaging box.

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions: a packaging box production color printing device, including a packaging box color printing machine body, a driving frame slidably arranged on both sides of the packaging box color printing machine body, and a UV printing head arranged between the two sets of driving frames, and a limiting mechanism is arranged on one side of the UV printing head, and the limiting mechanism includes:

[0008] A bidirectional threaded rod, which is rotatably disposed between two sets of support plates;

[0009] Limiting wheels, the distance between the two sets of limiting wheels is adjusted by the bidirectional threaded rod;

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The embodiment of the present application provides a color printing device to solve the problem that the position of the packaging box is easily offset during the color printing process of the packaging box, resulting in an error in the printing position of the pattern on the surface of the packaging box, and to limit the placement position of the packaging box without blocking the printing position of the packaging box.

[0030] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] The utility model embodiment discloses a color printing device for producing packaging boxes.

[0032] According to the attached Figure 1-5As shown, it includes a packaging box color printing machine body 1, a driving frame 101 slidably arranged on both sides of the packaging box color printing machine body 1, and a UV printing head 102 arranged between two groups of driving frames 101. The packaging box color printing machine body 1, the driving frame 101, the UV printing head 102 and other components constitute a packaging box color printing machine with model 7880C. When in use, the packaging box is placed on the top end surface of the packaging box color printing machine body 1, and then the driving frame 101 is controlled by a control device to slide along the outer wall of the packaging box color printing machine body 1, so that the UV printing head 102 arranged at the driving frame 101 performs color printing operation on the surface of the packaging box.

[0033] A limiting mechanism 2 is set on one side of the UV printing head 102. Through the setting of the limiting mechanism 2, when the UV printing head 102 moves along the outer wall of the packaging box color printing machine body 1, the packaging box placed on the packaging box color printing machine body 1 will not be shifted, and at the same time, the printing part of the packaging box will not be blocked. The limiting mechanism 2 includes a support plate 201, and the support plate 201 is fixedly set on one side of the UV printing head 102. The bidirectional threaded rod 202 is rotatably set between the two groups of support plates 201. The outer wall of the bidirectional threaded rod 202 is threadedly sleeved with two groups of threaded plates 203. The two groups of limiting wheels 204 are rotatably connected to the outer wall of one group of threaded plates 203 respectively. The limiting wheels 204 control the two groups of limiting wheels 204 through the bidirectional threaded rod 202. The spacing is adjusted, and a limiting rod 205 is fixedly connected between the two groups of support plates 201. One end of the two groups of threaded plates 203 is slidably set on the outer wall of the limiting rod 205. A nut is set on the outer wall of one end of the two-way threaded rod 202 extending to one side of the support plate 201, and two groups of thread grooves are opened on the outer wall of the two-way threaded rod 202, and the groove directions of the two groups of thread grooves are opposite, so that when the two-way threaded rod 202 is rotated, the two groups of threaded plates 203 set on the outer wall of the two-way threaded rod 202 and the limiting wheels 204 set on one side of the two groups of threaded plates 203 move to both sides or to the middle at the same time, so that the two groups of limiting wheels 204 can limit packaging boxes of different sizes, and the outer wall of the limiting wheel 204 contacts the side wall of the packaging box.

[0034] The positioning component 206 is used to position the packaging box during the color printing process, so that when the UV printing head 102 moves toward the packaging box, the packaging box will not move equally with the UV printing head 102. The positioning component 206 includes a card slot 2061, and the card slot 2061 is opened on the top end surface of the packaging box color printing machine body 1. One end of the positioning plate 2062 is slidably set inside the card slot 2061, and one end of the spring 2064 is connected to the bottom end surface of the positioning plate 2062. The setting position of the positioning plate 2062 is elastically controlled by the spring 2064. The bottom end surface of the card slot 2061 is provided with a connecting groove 2063 connected thereto, and the spring 2064 is arranged inside the connecting groove 2063. One end of the spring 2064 away from the positioning plate 2062 is fixedly connected to the inner bottom of the connecting groove 2063. When the positioning plate 2062 is in the initial state, one end of it is in a protruding state, that is, the spring 2064 connected to one end of the positioning plate 2062 is in an extended state. For details, please refer to the attached Figure 1 .

[0035] The color printing equipment for producing packaging boxes, by setting up a limiting mechanism 2 and a positioning component 206, ensures that the vibration generated during the movement of the UV printing head 102 will not cause the setting position of the packaging box to be offset, and the limiting mechanism 2 and the positioning component 206 will not block the printing surface of the packaging box, so that during the color printing process of the packaging box, the pattern on the surface of the packaging box is complete and the printing position of the pattern is highly accurate.
