Description

Technical Field

[0001] The utility model belongs to the technical field of labeling machine equipment, and in particular relates to a heating device for a labeling machine. Background Art

[0002] In a low temperature environment, in order to improve the stickiness of the label on the labeling machine, the existing solution is to heat the label. For example, patent application number 202220519475.1 discloses a label heating device for a labeling machine. After heating the water in the water tank, the label is heated by bonding the water tank to achieve a heating effect on the label. The label can be heated in a low temperature environment to improve the adhesion of the label.

[0003] Although the above-disclosed heating scheme can heat the label, it has the following defects during use: using a water tank to conduct heat to the label will result in a larger area of ​​the water tank that can conduct heat. In addition to the area in contact with the label, the label can be effectively heated. Other areas of the water tank that are not in contact with the label (hereinafter referred to as the invalid heating area) will continue to lose heat, causing the temperature in the water tank to lose faster, which not only wastes most of the heat, but also causes a large amount of power consumption in order to ensure the temperature of the water tank. In the existing solution, insulation material can be used to cover the invalid heating area on the water tank. Although this can reduce heat loss, the specifications of labels required for different types of products are also different, resulting in the width of each roll of labels being not uniform, causing the area of ​​the label in contact with the water tank to change, and the area of ​​the invalid heating area is not fixed. For example, after the width of the label becomes narrower, the area originally covered by the insulation material cannot be changed, and the uncovered heating area will still cause heat waste, and the invalid heating area cannot be flexibly covered according to the specifications of the label. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a heating device for a labeling machine, which uses the thermal insulation cotton in the water tank to make only the heat conduction plate on the water tank effectively conduct heat, and then when the label is in contact with the heat conduction plate for heating, other areas of the water tank can be insulated to reduce heat loss, thus avoiding most of the heat waste and reducing the power consumption of the heating tube. In conjunction with the adjustment mechanism, when driving the baffle to move, it can not only realize the function of the existing adjustment mechanism, but also cover the area where the label is not in contact with the heat conduction plate according to the width of each roll of label, thereby flexibly covering the invalid heating area and avoiding the heat waste after the label specifications are changed.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A labeling machine heating device comprises a mounting frame, a rectangular water tank is fixedly arranged at one end of the mounting frame, a rotating shaft is fixedly arranged at the other end of the mounting frame, a reel is rotatably arranged on the rotating shaft, a label is wound on the reel, brackets are arranged on the upper and lower sides of the water tank, rollers are rotatably arranged on the two brackets, a heating pipe is fixedly arranged in the water tank, the bracket is fixedly connected to the water tank, a cavity is opened on the inner wall of the water tank, an opening is opened on the left side of the water tank, a heat conducting plate is fixedly connected to the opening of the water tank, the left side of the heat conducting plate is in the same plane as the outer surface of the water tank, two adjustment mechanisms are arranged on the left side of the water tank, and the two adjustment mechanisms are respectively located on both sides of the heat conducting plate;

[0007] Adjustment mechanism: a fixed block is fixedly connected to the upper part of the left side of the water tank, a screw rod is rotatably connected to the side of the fixed block, a movable block is threadedly connected to the screw rod, a baffle is fixedly connected to the bottom of the movable block, the right side of the baffle is fitted with the left side of the water tank, a groove is provided on the right side of the baffle, a guide block is fixedly connected to the lower part of the left side of the water tank, a slide groove is provided on the top of the guide block which is slidably connected to the baffle, and thermal insulation cotton is provided in the inner cavity of the water tank and the groove of the baffle.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. Through the thermal insulation cotton in the water tank, only the heat conduction plate on the water tank can effectively conduct heat. Then, when the label is in contact with the heat conduction plate for heating, other areas of the water tank can be insulated to reduce heat loss, that is, to avoid most of the heat waste and reduce the power consumption of the heating tube. Moreover, in conjunction with the adjustment mechanism, when driving the baffle to move, it can not only separate the label and the heat conduction plate, so that when the equipment is shut down or the temperature rises, the label is prevented from being too close to the heat conduction plate and causing overheating, thereby realizing the function of the existing adjustment mechanism, but also can cover the area where the label and the heat conduction plate are not in contact according to the width of each roll of labels, thereby flexibly covering the invalid heating area and avoiding heat waste after the label specifications are changed.

[0012] 2. The copper plate is used as the heat conducting plate, so that the heat conducting plate has a good heat conducting effect. The baffle is tilted to facilitate the baffle to be inserted between the label and the heat conducting plate during movement. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in 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.

Example

[0019] See attached Figure 1-3 As shown, a labeling machine heating device comprises a mounting frame 1, a rectangular water tank 2 is fixedly arranged at one end of the mounting frame 1, a rotating shaft 3 is fixedly arranged at the other end of the mounting frame 1, a reel 4 is rotatably arranged on the rotating shaft 3, a label 5 is wound on the reel 4, brackets 6 are arranged on the upper and lower sides of the water tank 2, rollers 7 are rotatably arranged on the two brackets 6, a heating pipe is fixedly arranged in the water tank 2, the bracket 6 is fixedly connected to the water tank 2, a cavity is opened on the inner wall of the water tank 2, an opening is opened on the left side of the water tank 2, a heat conducting plate 8 is fixedly connected to the opening of the water tank 2, the left side of the heat conducting plate 8 is in the same plane as the outer surface of the water tank 2, and two adjustment mechanisms are arranged on the left side of the water tank 2, and the two adjustment mechanisms are respectively located on both sides of the heat conducting plate 8;

[0020] Adjustment mechanism: A fixed block 9 is fixedly connected to the upper part of the left side of the water tank 2, and a screw rod 10 is rotatably connected to the side of the fixed block 9. A movable block 11 is threadedly connected to the screw rod 10, and a baffle 12 is fixedly connected to the bottom of the movable block 11. The right side of the baffle 12 fits with the left side of the water tank 2, and a groove is provided on the right side of the baffle 12. A guide block 13 is fixedly connected to the lower part of the left side of the water tank 2, and a slide groove slidably connected to the baffle 12 is provided on the top of the guide block 13. Insulation cotton is provided in the inner cavity of the water tank 2 and the groove of the baffle 12. The heat conducting plate 8 is a copper plate, and the adjacent sides of the two baffles 12 are inclined.

[0021] Working principle: when heating the label 5, the label 5 is pulled out from the reel 4, and is wound from the upper side of the roller 7 above the water tank 2 to the left side of the water tank 2, and then is wound out from the lower side of the roller 7 below the water tank 2 to carry out the labeling work. At this time, the non-stick side of the label 5 is kept in contact with the left side of the water tank 2, and when passing through the heat conducting plate 8, it contacts the heat conducting plate 8. In a low temperature environment, when the label 5 needs to be heated, the heating tube heats the water in the water tank 2, and the heat conducting plate 8 conducts the temperature in the water tank 2 to the label 5, so that the glue on the label 5 is heated to increase its viscosity, and the heat insulation cotton keeps the water tank 2 warm to prevent heat from being lost from other areas of the water tank 2. When the equipment is shut down or the temperature rises, the screw rod 10 is screwed, and the baffle 12 is moved along the slide track of the guide block 13 as the screw rod 10 rotates through the movable block 11, and the two baffles 12 are brought together, and the label is inserted into the inclined surface of the baffle 12. The label 5 is moved between the label 5 and the heat conducting plate 8 until the two baffles 12 are in contact. At this time, the label 5 is blocked by the baffle 12 and is not in contact with the heat conducting plate 8 and is no longer heated. If the gap between the label 5 and the heat conducting plate 8 is too narrow, and it is inconvenient to insert the baffle 12, the side of the label 5 can be pulled to assist the insertion of the baffle 12. When replacing labels 5 of different specifications for heating, if the width of a roll of label 5 is narrow and cannot completely cover the heat conducting plate 8, the water tank 2 is heated first, and the heat conducting plate 8 is used to conduct heat to the label 5, and then the screw 10 is screwed to move the baffle 12. The difference is that only the two baffles 12 need to be moved to the edges of both sides of the label 5. At this time, the area of ​​the heat conducting plate 8 not covered by the label 5 is covered by the baffle 12, and the thermal insulation cotton on the baffle 12 keeps this area warm, reduces heat loss, and achieves the effect of flexibly covering the invalid heating area.

[0022] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model; therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description. Therefore, it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model, and any figure marks in the claims should not be regarded as limiting the claims involved.
