Detailed Description

The technical solutions of the embodiments of the present utility model will be explained and illustrated below with reference to the drawings of the embodiments of the present utility model, but the following embodiments are only preferred embodiments of the present utility model, and not all embodiments. Based on the examples in the implementation manner, other examples obtained by a person skilled in the art without making creative efforts fall within the protection scope of the present utility model.

In the following description, directional or positional relationships such as the terms "inner", "outer", "upper", "lower", "left", "right", etc., are presented for convenience in describing the embodiments and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the utility model.

Referring to fig. 1-5, the present embodiment provides a label dryer, which includes a frame 1, a conveyor belt 2 and an oven 3, wherein the conveyor belt 2 is mounted on the frame 1, the oven 3 is fixedly mounted on the frame 1 and spans over the upper portion of the conveyor belt 2, the conveyor belt 2 passes through the oven 3, two sides of the oven 3 are respectively provided with openings to form a feed inlet and a discharge outlet, labels carried by the conveyor belt 2 enter the oven 3 through the feed inlet, and are output out of the oven 3 from the discharge outlet. The label can be referred to as part a in figures 3 and 4

The oven 3 is provided with a hot air blower 43 for blowing hot air toward the conveyor belt 2, as a specific embodiment:

referring to fig. 2, the air heater 43 comprises a fan housing 41 and a fan 43 mounted on the top of the oven 3, wherein the lower end of the fan housing 41 is provided with an opening, and the opening side of the fan housing extends into the oven 3 and is positioned on the upper part of the conveyor belt 2; the fan housing 41 is provided with an electric heating net 42, the fan 43 is installed on the ground or the oven 3, the air outlet end of the fan 43 is communicated with the top of the fan housing 41, when the fan housing 41 works, the electric heating net 42 is electrified to generate heat, the fan 43 blows air into the fan housing 41, the air blown into the fan housing 41 is heated to form hot air when passing through the electric heating net 42, and the hot air finally blows on labels on the conveying belt 2 to dry the labels.

In addition, as shown in fig. 2, in order to make the air blown by the fan 43 pass through the electric heating net 42 more uniformly, in this embodiment, an air equalizing plate 44 located at the upper part of the electric heating net 42 is disposed in the air cover 41, where the air equalizing plate mainly plays a role of dispersing air, and is mainly composed of a plate body structure with a plurality of through holes uniformly formed on the surface, and the effect of dispersing air equalizing is achieved by virtue of the through holes on the plate body.

Since the labels are lighter, if they are not limited, they are easy to deviate from the conveyor belt 2 under the blowing of hot air, so in this embodiment, in order to avoid deviation of the labels under the blowing of hot air, as shown in fig. 1 and fig. 4, two ribs 21 surrounding the conveyor belt 2 along the circumferential direction are formed on the outer surface of the conveyor belt 2, and an area for placing the labels is formed between the two ribs 21 at intervals, which is worth noting that the ribs 21 and the conveyor belt 2 are in an integral structure and can rotate synchronously with the conveyor belt 2.

The spacing between the ribs 21 is adapted to the width of the label, which is slightly larger than the width of the label.

When the label collecting device is used, the area between the two convex ribs 21 is forwards conveyed by the conveying belt 2, the two convex ribs 21 can limit the two sides of the label, and the label collecting device can prevent the hot air blown by the hot air blower 43 from shifting the label to the two sides, so that the label is basically forwards conveyed along a straight line in the whole process, and the label collecting device is more orderly and convenient for subsequent label collecting work.

In addition, the labels may also float up and down on the conveyor belt 2 greatly under the blowing of hot air, so in this embodiment, as shown in fig. 3-5, two limiting strips 5 extending along the length direction of the conveyor belt 2 are disposed inside the two ribs 21, and it should be noted that the two limiting strips 5 are kept still all the time, and the ribs 21 can move relative to the limiting strips 5.

The bottom walls of the two limiting strips 5 are parallel to the conveying surface of the conveying belt 2 and are arranged at intervals between the two limiting strips and the conveying surface of the conveying belt 2 so as to allow the side edges of the labels to enter. So two spacing 5 can realize spacing to the both sides edge of label in the upper portion of label, avoids the label to take place great upper and lower floating under the blowing of hot-blast.

It should be noted that, for most labels, the printed marks are generally concentrated in the middle area of the label, and there is no printed mark on two sides of the label, so the existence of the limit bar 5 will not have a substantial influence on the printed mark in the middle even if a certain shielding is formed on two sides of the surface of the label.

For convenience of explanation, in this embodiment, in the direction shown in fig. 2, two ends of the conveying belt 2 are respectively denoted as a first end and a second end, and correspondingly, two ends of the limit bar 5 are respectively denoted as a first end and a second end, where the first end of the conveying belt 2 and the first end of the limit bar 5 are located on the same side, and the second end of the conveying belt 2 and the second end of the limit bar 5 are located on the same side.

As shown in fig. 1 and fig. 3, a distance is formed between the first end of the limit strip 5 and the first end of the conveyor belt 2, the distance is used as a feeding area, the labels are placed in the area, and finally, the conveyor belt 2 can input the labels into the bottom of the limit strip 5; on the contrary, if the first end of the limit bar 5 is relatively close to the first end of the conveyor belt 2, the tag cannot be directly placed between the two ribs 21 due to the blocking of the limit bar 5, and then the tag needs to be inserted into the bottom of the limit bar 5 at the front side of the first end of the limit bar 5, so that the operation is obviously laborious.

Similarly, a distance is provided between the second end of the limit bar 5 and the second end of the conveyor belt 2, so that after the label is output from the second end of the limit bar 5, the limit bar 5 is not blocked, and the label can be directly taken out from between the two ribs 21.

Because the thickness of different types of labels is different, in order to adapt to the labels with various different thicknesses, in this embodiment, a height adjusting mechanism for adjusting the height of the spacing 5 is arranged between the frame 1 and the spacing 5, so that the height of the spacing 5 can be adjusted by the height adjusting mechanism, the spacing between the spacing 5 and the conveying belt 2 is adjusted, and the spacing can adapt to the thickness of the labels.

In this embodiment, two identical height adjusting mechanisms are preferably adopted on the same limit bar 5, and the two height adjusting mechanisms are respectively connected with two ends of the limit bar 5. In this embodiment, one of the height adjusting mechanisms is specifically described as an example:

referring to fig. 5, the height adjusting mechanism includes a bracket 61, a positioning sleeve 62 and an adjusting rod 63, wherein the bracket 61 is fixed on the frame 1, the positioning sleeve 62 is fixed on the bracket 61, and the adjusting rod 63 is vertically movably inserted into the positioning sleeve 62 and the lower end of the adjusting rod is fixed with the limit bar 5; the positioning sleeve 62 is also provided with a locking piece for locking the position of the adjusting rod 63.

The locking member is preferably a bolt 64 which is screwed onto the positioning sleeve 62, and the inner end of the bolt 64 abuts against the adjusting rod 63 to lock the position of the adjusting rod 63.

When the height of the limit bar 5 is adjusted, the bolt 64 is screwed down when the height is adjusted to the required height, and the bolt 64 is screwed down when the height is adjusted to the required height.

In addition, in order to know the adjustment distance clearly, in this embodiment, be equipped with the scale mark on the periphery wall of movable rod, rely on the scale mark can know the height that corresponds at present.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
