Description

Technical Field

[0001] The utility model relates to the technical field of packaging box printing, in particular to packaging box printing equipment with a placement deviation correction function. Background Art

[0002] Packaging boxes are common items in daily life, such as moon cake boxes, toy boxes, medicine boxes, gift boxes, etc. Packaging boxes can ensure the safety of products during transportation, and the patterns printed on the packaging boxes can enhance the grade of the products.

[0003] As shown in the reference case "A packaging box printing device" announcement number "CN211616977U3", the position of the packaging box can be adjusted before printing to prevent deviation of the printed pattern, and the ink on the surface of the printed packaging box can be quickly cooled and formed to prevent the ink from being transferred to the back of other packaging boxes when stacked;

[0004] When existing packaging box printing equipment prints in a low temperature environment, due to the low printing environment temperature, the fluidity and adhesion of the ink are weakened when printing the packaging box, the ink may be uneven and the ink drying time will be longer in the low temperature environment, affecting the printing efficiency.

[0005] Therefore, a packaging box printing device with a placement correction function is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a packaging box printing device with a placement correction function in order to solve the above-mentioned problem, thereby improving the problem that when the existing packaging box printing device is printed in a low temperature environment, the fluidity and adhesion of the ink are weakened due to the low printing environment temperature when printing the packaging box, the ink may be uneven and the ink drying time is prolonged in a low temperature environment, affecting the printing efficiency.

[0007] The utility model achieves the above-mentioned purpose through the following technical solutions: a packaging box printing device with a placement correction function, comprising: a fixed frame, a conveyor belt is fixedly installed inside the fixed frame, a printing press is fixedly installed on one side of the fixed frame, and the printing press is located on one side of the conveyor belt; a guide preheating mechanism, the guide preheating mechanism for correcting and guiding the packaging box is arranged on one side of the fixed frame; wherein the guide preheating mechanism comprises a positioning frame fixedly installed on one side of the fixed frame, a preheating component is arranged on one side of the positioning frame, and a guide component is arranged on one side of the fixed frame. When printing, the packaging box can be preheated by the preheating component, so as to improve the adhesion of ink and the printing quality, and ensure that the temperature of the packaging box reaches the optimal printing condition, so that the ink can be quickly dried and solidified on the surface of the packaging box, thereby improving the printing efficiency, and the packaging box can be corrected by the guide component before the packaging box passes through the preheating component, ensuring that the position and angle of each packaging box when transmitted on the conveyor belt are correct, so as to prevent the pattern from being offset or skewed during printing.

[0008] Preferably, the preheating assembly includes a movable plate arranged inside the positioning frame, the movable plate is located above the conveyor belt, a heater is fixedly installed inside the movable plate, and a heat-conducting contact plate is fixedly connected to the bottom of the heater. The movable plate extends from one side of the heat-conducting contact plate, and when the packaging box passes under the movable plate, it can directly contact with the top of the packaging box to transfer heat, so as to preheat the printing surface of the packaging box, ensuring that the temperature of the packaging box reaches the optimal printing conditions, so that the ink can quickly dry and solidify on the surface of the packaging box, thereby improving printing efficiency.

[0009] Preferably, the preheating assembly also includes two leveling wheels rotatably installed on the bottom of the movable plate, and the two leveling wheels are respectively located on both sides of the heat-conducting contact plate. When the packaging box passes through the bottom of the movable plate, the two leveling wheels can also be used to level the packaging box when the packaging box passes through, ensuring that its surface is flat, so as to maintain the consistency and precise alignment of the pattern during the printing process.

[0010] Preferably, a fixed plate is fixedly installed inside the positioning frame, and two support rods are slidably installed on one side of the fixed plate. The surfaces of the two support rods are slidably sleeved with connection blocks, and the two connection blocks are fixedly connected to the two sides of the movable plate respectively. The surface of the support rod is sleeved with a spring, and the other end of the spring is fixedly connected to the surface of the fixed plate. When the movable plate is used, the two support rods can be pushed down by the spring, and the movable plate can be driven to move down synchronously. When preheating, the movable plate can be moved down to ensure that the heat-conducting contact plate is in closer and more uniform contact with the surface of the packaging box. This contact ensures that heat can be effectively transferred to the entire surface of the packaging box, thereby improving the preheating effect and optimizing the printing quality.

[0011] Preferably, the guide assembly includes a bidirectional screw rotatably mounted on one side of a fixed frame, and two positioning frames are slidably mounted on one side of the fixed frame. One end of the bidirectional screw passes through the two positioning frames, and the bidirectional screw is threadedly connected to the two positioning frames respectively. The two positioning frames can be synchronously adjusted to move closer to or farther away from each other by rotating the bidirectional screw and performing threaded movement with the two positioning frames. The bidirectional screw can be synchronously adjusted to adapt to different packaging boxes, thereby performing guiding and deviation correction on different packaging boxes.

[0012] Preferably, the positioning frame is arranged in an L shape, and guide blocks are fixedly installed inside the two positioning frames. The guide blocks are arranged in a triangular shape, and a plurality of rollers are rotatably installed on the inclined surfaces of the guide blocks. Through the interaction between the inclined surfaces of the guide blocks and the rollers, the packaging box can be effectively guided to pass smoothly along the correct path. The rollers reduce friction when contacting the packaging box, preventing the packaging box from shifting or tilting during transportation, thereby ensuring that the packaging box is aligned before entering the printing press.

[0013] Preferably, an import frame is fixedly installed on one side of the fixed frame, and a blanking plate is fixedly installed inside the import frame. The packaging box can be placed in the import frame and the packaging box can be blanked through the blanking plate, so that the packaging box can be preliminarily sorted through the import frame before the guiding component is installed.

[0014] The beneficial effects of the utility model are:

[0015] 1. When printing, the packaging box can be preheated through the preheating component to improve the ink adhesion and printing quality, and ensure that the temperature of the packaging box reaches the optimal printing condition, so that the ink can quickly dry and solidify on the surface of the packaging box to improve printing efficiency. Before the packaging box passes through the preheating component, the packaging box can be corrected through the guide component to ensure that the position and angle of each packaging box when it is transmitted on the conveyor belt are correct to prevent the pattern from shifting or skewing during printing;

[0016] 2. Through the interaction between the inclined surface of the guide block and the roller, the packaging box can be effectively guided to pass smoothly along the correct path. The roller reduces friction when contacting the packaging box, preventing the packaging box from shifting or tilting during transportation, ensuring that the packaging box is aligned before entering the printing press.
