Description

A labeling device Technical Field

[0001] This utility model relates to the field of labeling devices, and more particularly to a labeling equipment. Background Technology

[0002] Labeling machines are specific mechanical devices that affix labels to packaging containers. Due to their excellent applicability, labeling machines are now widely used in many industries such as pharmaceuticals, food, light industry, and daily chemicals. With the increasing application and technological development, the mechanical forms have also diversified to meet the different needs of different industries. Traditional automatic adsorption labeling machines use evenly distributed fine holes on the label suction block to adsorb labels.

[0003] However, the above-mentioned technologies have at least the following technical problems:

[0004] The incoming label material may not be able to maintain a flat posture. When it is bent, the label suction block will have difficulty adsorbing the entire label, which will easily lead to the label falling off. Summary of the Invention

[0005] The purpose of this invention is to provide a labeling device to solve the problem of uneven label adsorption by the label suction block in the prior art.

[0006] The technical solution of this utility model is: a labeling device, including a base arranged in a horizontal direction, a mounting frame fixed in a vertical direction on the base, and a labeler arranged on the mounting frame;

[0007] The labeler is provided with a label suction block at the bottom, which is set as a flat surface for connecting the label. The labeler and the mounting frame are slidably connected through a labeling drive mechanism, which can drive the label to move up and down in the vertical direction.

[0008] The bottom end of the label-absorbing block has several vertically oriented adsorption holes, and the multiple adsorption holes are connected to a negative pressure device, so that the bottom end of the labeler generates a negative pressure adsorption force.

[0009] A printer is installed on the base corresponding to the labeler, and the label is generated by the printer; the label suction block is located near the paper output port of the printer;

[0010] An air outlet mechanism is provided on the other side of the paper output port of the printer opposite to the label suction block. The air outlet mechanism includes a horizontally arranged air duct. The air duct is hollow, and an air outlet is opened on the outer wall of the air duct at the end facing the label suction block. The air outlet is connected to a fan through the hollow structure of the air duct.

[0011] Preferably, the labeling drive mechanism includes a lifter and a translater;

[0012] The lifting device has a lifting cylinder fixed to the mounting frame in a vertical direction, and a lifting slider is fixed to the actuating end of the lifting cylinder.

[0013] The translation device includes a translation cylinder fixed to the lifting slider, and the labeler is fixed to the actuating end of the translation cylinder.

[0014] Preferably, the labeler includes a labeling base, which is fixed horizontally to the actuating end of the translation cylinder; an auxiliary cylinder is vertically mounted on the labeling base, and the label suction block is connected to the auxiliary cylinder. The auxiliary cylinder can drive the label suction block to perform vertical lifting and lowering movements, and cooperate with the lifting device to perform secondary pressing during the labeling action.

[0015] Preferably, the labeling base is provided with a support frame, the support frame is n-shaped, the body of the auxiliary cylinder is fixed to the top of the support frame, and the actuating end of the auxiliary cylinder passes through the top of the support frame in a vertical direction.

[0016] Preferably, the labeling base is provided with a guide sleeve, which penetrates the labeling base vertically and is hollow along the axis for the actuating end of the auxiliary cylinder to pass through, so that the actuating end of the auxiliary cylinder can move along the axial direction of the guide sleeve.

[0017] Preferably, the guide sleeves are arranged in pairs, and the label-absorbing block is fixed to the actuating end of the auxiliary cylinder through a connecting mechanism. The connecting mechanism includes a pair of guide shafts, one end of which is fixed to the label-absorbing block, and the other end passes through the guide sleeve and is fixed to each other through a horizontally arranged connecting plate. The actuating end of the auxiliary cylinder is fixed to the middle section of the connecting plate.

[0018] Compared with the prior art, the advantages of this utility model are:

[0019] (1) In this application, the air outlet mechanism is located on the opposite side of the printer paper outlet. The upward air blows the curled label to ensure that the label is completely attached to the adsorption surface of the label suction block, eliminating adsorption dead corners and improving adsorption reliability.

[0020] (2) The translation device drives the labeler to move horizontally to the paper output port of the printer, so that the label suction block directly absorbs the newly generated label.

[0021] (3) After the lifting device completes the initial labeling, the auxiliary cylinder drives the labeler to press down a second time to enhance the tightness of the label and the object. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to specific embodiments:

[0029] As shown in Figures 1 and 2, a labeling device includes a horizontally positioned base 11 and a vertically fixed mounting frame 12. A label applicator 2 is mounted on the mounting frame 12. The bottom end of the label applicator 2 has a label-absorbing block 21, which is flat and used to attach labels. The label applicator 2 and the mounting frame 12 are slidably connected via a labeling drive mechanism 3. The labeling drive mechanism 3 can move the label vertically up and down, thereby attaching the label to the object to be labeled below the label-absorbing block 21.

[0030] In this embodiment, the bottom end of the label suction block 21 has several vertically oriented suction holes 22, which are connected to a negative pressure device, thereby generating a negative pressure suction force at the bottom end of the label applicator 2. Furthermore, a printer 4 is mounted on the base 11 corresponding to the label applicator 2, and the labels are generated by the printer 4. The label suction block 21 is positioned near the paper output port of the printer 4. This arrangement allows the labels generated by the printer 4 to be directly absorbed by the label suction block 21.

[0031] Furthermore, due to the internal temperature of the printer 4, the newly generated labels often curl downwards. This results in only a portion of the suction holes 22 adhering to the label, which can easily lead to poor label adhesion. To solve this problem, this application provides an air outlet mechanism 5 on the opposite side of the paper outlet of the printer 4 from the label suction block 21. By generating an upward airflow, the downward curled portion of the label is blown into contact with the label suction block 21.

[0032] Specifically, as shown in Figure 3, the air outlet mechanism 5 includes a horizontally arranged air duct 51. The air duct 51 is hollow, and an air outlet 52 is opened on the outer wall of the air duct 51 facing the label suction block 21. Multiple air outlets 52 can be set along the length of the air duct 51. The air outlets 52 are connected to a fan through the hollow structure of the air duct 51. The air force generated by the fan acts on the label through the hollow structure of the air duct 51 and the air outlets 52.

[0033] As shown in Figure 1, the labeling drive mechanism 3 includes a lifter 31 and a translator 32. The lifter 31 has a lifting cylinder 311 fixed vertically to the mounting bracket 12, and a lifting slider 312 is fixed to the actuating end of the lifting cylinder 311. The translator 32 includes a translating cylinder fixed to the lifting slider 312, and the labeler 2 is fixed to the actuating end of the translating cylinder. The lifter 31 drives the labeler 2 to perform the labeling action, and the translator 32 drives the label suction block 21 and the labeler 2 to move towards the printer 4 when the printer 4 generates a label, thereby better attaching the label.

[0034] As shown in Figure 4, the labeler 2 includes a labeling base 23, which is fixed horizontally to the actuating end of the translation cylinder. An auxiliary cylinder 24 is vertically mounted on the labeling base 23. The label suction block 21 is connected to the auxiliary cylinder 24, which drives the label suction block 21 to move vertically up and down. This, in conjunction with the lifting device 31, provides secondary pressure during the labeling process, resulting in a more secure label adhesion.

[0035] The labeling base 23 is equipped with a support frame 25 and a guide sleeve 26. The support frame 25 is n-shaped, and the body of the auxiliary cylinder 24 is fixed to the top of the support frame 25. The actuating end of the auxiliary cylinder 24 passes vertically through the top of the support frame 25. The guide sleeve 26 passes vertically through the labeling base 23 and is hollow along its axis to allow the actuating end of the auxiliary cylinder 24 to pass through, enabling the actuating end of the auxiliary cylinder 24 to move along the axial direction of the guide sleeve 26.

[0036] Furthermore, the guide sleeves 26 are arranged in pairs, and the label-absorbing block 21 is fixed to the actuating end of the auxiliary cylinder 24 via a connecting mechanism 27. The connecting mechanism 27 includes a pair of guide shafts 271, one end of which is fixed to the label-absorbing block 21, and the other end passes through the guide sleeves 26 and is fixed to each other via a horizontally arranged connecting plate 272. The actuating end of the auxiliary cylinder 24 is fixed to the middle section of the connecting plate 272. This arrangement allows the auxiliary cylinder 24 and the label-absorbing block 21 to have two connecting ends, thereby making the pressure of the label-absorbing block 21 on the label more uniform during the labeling action.

[0037] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and therefore, all changes falling within the meaning and scope of the equivalents of the claims are intended to be included within this utility model.
