Description

Technical Field

[0001] This utility model relates to the field of printing press technology, and more specifically, to a clean label printing press. Background Technology

[0002] Label printing machines are specialized equipment used to print various labels, such as self-adhesive labels, wine labels, and pharmaceutical labels. They typically have highly automated and precise control systems, enabling them to print complex patterns and text on different materials. They are an important means of conveying product information and brand identification, and are widely used in commerce, industry, and daily life.

[0003] However, during the label printing production process, when the finished labels reach a certain load capacity on the take-up roller, the printing machine needs to be stopped to replace the new take-up roller to continue label printing production. This takes a long time and is inconvenient, which reduces production efficiency. In addition, frequent manual operation can easily contaminate the labels.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a clean label printing machine to solve the problem of needing to stop the label printing machine to replace the new take-up roller to continue printing production.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a clean label printing machine, including a printing machine body, the printing machine body including an output roller, a printing chamber, a transfer structure and a plurality of take-up rollers arranged sequentially along the label conveying direction, the peripheral wall of the take-up roller is clamped with a carrier, the transfer structure includes a squeezing member and a cutting member, when the carrier reaches the upper limit of the bearing capacity, the squeezing member and the cutting member move in a direction that approaches each other to cut the label and fix it to the adjacent carrier on the side close to the output roller.

[0007] The present invention is further configured such that: the extrusion component and the cutting component are symmetrically arranged along the height direction of the printing machine body and are slidably connected in the height direction of the printing machine body, and both the extrusion component and the cutting component are slidably connected in the height direction of the printing machine body.

[0008] The present invention is further configured such that: a groove is provided at one end of the extruder near the cutter, and when the cutter and the extruder move in a direction that brings them closer together, the end of the cutter near the extruder is inserted into the groove.

[0009] The present invention is further configured such that: a recess is provided at the corner of the extrusion member near the cutting member, and the curvature of the recess is the same as the curvature of the bearing member.

[0010] The present invention is further configured such that: the outer peripheral wall of the carrier is coated with adhesive, and when the extruder moves to the point where the recessed peripheral wall abuts against the peripheral wall of the carrier, the cut label is fixedly connected to the carrier by adhesive.

[0011] The present invention is further configured such that: an annular slide rail is provided on the bottom side wall of the printing press body, and several of the take-up rollers move cyclically in the slide rail in a clockwise direction.

[0012] In summary, this utility model has the following beneficial effects: when the carrier reaches its upper limit, the label can be cut and glued to a new carrier while the printing machine body is working continuously through the transfer structure to continue the cloth rolling operation.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Example: A clean label printing machine, such as Figures 1-2 As shown, the printing press body 1 is made of stainless steel. The high strength and corrosion resistance of stainless steel allow the body of the printing press body 1 to resist the erosion of most chemicals and withstand greater external forces. The surface of stainless steel is relatively smooth, which facilitates daily cleaning and disinfection of the printing press body 1, maintaining its cleanliness and preventing labels from being contaminated during production. The printing press body 1 includes an output roller 2, a printing chamber 3, a transfer structure 4, and several take-up rollers 5 arranged sequentially along the label conveying direction. The substrate conveyed by the output roller 2 enters the printing chamber 3 and is then processed through steps such as design, plate making, printing, and drying to produce the required labels.

[0019] like Figures 1-2 As shown, a cylindrical support member 6 for rolling cloth labels is snapped onto the peripheral wall of the take-up roller 5. The support member 6 is detachably connected to the take-up roller 5. This support member 6 is made of cardboard and is manufactured through processes such as winding, gluing, extrusion, drying, and cutting, so that it can provide support for the label and be rolled up in a roll for easy storage. The transfer structure 4 includes an extruder 7 and a cutter 8. The extruder 7 and the cutter 8 are symmetrically arranged along the height direction of the printing machine body 1. The cutter 8 and the extruder 7 can slide closer to each other or further away from each other along the height direction of the printing machine body 1. The extruder 7 and the cutter 8 can be moved along the direction of closer to each other or further away from each other by a motor drive. The extruder 7 and the cutter 8 are located on both sides of the label output from the printing chamber 3 along its height direction.

[0020] like Figures 1-3 As shown, a groove 10 is provided at one end of the extruder 7 near the cutter 8. When the cutter 8 and the extruder 7 move towards each other and the end of the cutter 8 near the extruder 7 is inserted into the groove 10, the label is cut. An arc-shaped recess 11 is provided at the corner of the extruder 7 near the cutter 8. The outer peripheral wall of the carrier 6 is coated with a layer of glue. The arc of the recess 11 is the same as the arc of the carrier 6, so that when the extruder 7 drives the label to move to the carrier 6, it can stick tightly to the peripheral wall of the carrier 6, thereby obtaining a larger contact area. This helps to fix the cut label to the carrier 6 under the pressure of the extruder 7 with glue. The label is subjected to downward pressure, and the cut label is fixed to the new carrier 6 with glue. When the carrier 6 reaches the upper limit of the roll capacity, the label can be cut and fixed to the adjacent carrier 6 near the output roller 2 through the transfer device to continue the roll operation, realizing the effect of continuous production and improving production efficiency.

[0021] like Figures 1-2 As shown, a circular slide rail 9 is provided on the bottom side wall of the printing machine body 1, so that several take-up rollers 5 can be independently rotated in a clockwise direction and connected in the slide rail 9 when rolling the cloth label. At the same time, several take-up rollers 5 move in a clockwise direction in the slide rail 9, so that the carrier 6 that has completed the cloth rolling operation after cutting moves in the slide rail 9 with the take-up rollers 5. The operator only needs to apply a pulling force to the carrier 6 that has completed the cloth rolling operation along the side away from the printing machine body 1 to remove and store it, and snap on a new carrier 6. The multiple take-up rollers 5 provide the operator with sufficient time to replace the carrier 6, which is simple and convenient.

[0022] Working principle: When the carrier 6, which is performing the cloth rolling operation, reaches the upper limit of the cloth rolling capacity, the motor drives the extrusion piece 7 and the cutting piece 8 to move in a direction that approaches each other. This causes the cutting piece 8 to insert into the groove 10 to cut the label during conveying. At the same time, the recess 11 on the extrusion piece 7 applies pressure to the label, so that the cut label is tightly attached to the peripheral wall of the carrier 6 below the extrusion piece 7 and fixed with glue. This achieves the effect of continuous cloth rolling operation for the label. The carrier 6, which has completed the cloth rolling operation, moves cyclically in the slide rail 9 with the take-up roller 5. Applying a pulling force to the carrier 6, which has completed the cloth rolling operation, along the side away from the printing machine body 1, allows it to be removed and stored, and a new carrier 6 to be snapped on.

[0023] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
