Description

Technical Field

[0001] This utility model relates to the field of labeling technology, and in particular to a label preheating auxiliary labeling device for a labeling machine. Background Technology

[0002] The labeling machine uses self-adhesive roll labeling paper, and the label is applied to the outer surface of the container by rolling.

[0003] A search revealed a labeling mechanism for a vertical labeling machine (publication number: CN221986827U), comprising an electrical control box and a frame connected to its top. The frame is equipped with a conveyor chain, a bottle-separating mechanism is located at the product inlet of the conveyor chain, a labeling mechanism is located on one side of the middle section of the conveyor chain, a vertical rolling labeling mechanism is located on one side of the labeling mechanism, a positioning and clamping mechanism is located opposite the vertical rolling labeling mechanism, and an auxiliary labeling mechanism is located at the top of the vertical rolling labeling mechanism. The positioning and clamping mechanism includes a fixing plate connected to the top of the frame. The top of the fixed plate is connected to a fixed block via a support rod. An electric push rod is connected to one side of the fixed block. A moving plate is provided at the piston rod end of the electric push rod. An electric heating plate is connected to one side of the moving plate. A positioning plate is connected to one side of the electric heating plate. The vertical rolling labeling mechanism includes a vertical belt located on one side of the top of the conveyor chain. A top plate is provided on the top of the vertical belt. The auxiliary labeling mechanism includes a hot air blower connected to the top of the top plate. The output end of the hot air blower is connected to an air supply pipe. Multiple air nozzles vertically located on the top of the vertical belt are connected to the bottom of the air supply pipe.

[0004] Existing technology preheats labels by having them contact a heated plate. However, during the release process of the rolled-up labels, it is necessary to adjust the guide rollers for the released labels. Therefore, improving and optimizing the preheating of labels on the guide rollers is relatively reasonable. On the one hand, it can ensure the compactness of the overall structure, and on the other hand, it can ensure that the released labels are preheated evenly, thus ensuring the labeling quality. There is room for optimization in the existing technology of using air blowing and plates to preheat labels.

[0005] To address this, we propose a label preheating auxiliary labeling device for labeling machines. Utility Model Content

[0006] The present invention mainly addresses the technical problem of insufficient compactness of the preheating label structure and poor preheating effect, and provides an auxiliary labeling device for label preheating in a labeling machine.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a label preheating auxiliary label-sleeving device for a label-sleeving machine, comprising:

[0008] Mounting base, the top of which is fixedly mounted with a heating rod and a gasket, a heating sleeve is rotatably connected to the heating rod, and a label is provided on one side of the gasket;

[0009] A limiting structure, mounted on the mounting base, is used to press the label against the side wall of the heating sleeve. The limiting structure includes a guide roller, a sliding rod, and an adjusting screw. The sliding rod is slidably mounted on the mounting base, and two rotatable guide rollers are symmetrically arranged on the sliding rod. The adjusting screw is threadedly connected to the mounting base and can adjust the position of the sliding rod.

[0010] In a preferred embodiment of this utility model, the heating sleeve forms a cylindrical structure, the lower end of the heating sleeve is rotatably connected to the washer, the heating rod is located inside the cavity of the washer, and the outer wall of the heating sleeve is provided with anti-slip texture.

[0011] In a preferred embodiment of this utility model, the sliding rod is formed into a rod with a horizontal cross-section of U-shape, and the lower ends of the two guide rollers are rotatably connected to the sliding rod. The two guide rollers are symmetrically distributed about the heating rod as the axis.

[0012] In a preferred embodiment of the present invention, the limiting structure further includes a stop block and an adjusting nut. The stop block is fixedly connected to the sliding rod, and the adjusting nut is threadedly connected to the adjusting screw. A spring is provided between the stop block and the adjusting nut, and the adjusting nut can compress the spring to deform.

[0013] In a preferred embodiment of this utility model, the stop block has a hole, the adjusting screw rotates through the hole, and the spring is sleeved on the adjusting screw.

[0014] In a preferred embodiment of this utility model, the limiting structure further includes a slider, with the slider fixedly mounted at the bottom of the sliding rod, and the sliding rod slidably connected to the mounting base via the slider.

[0015] In a preferred embodiment of this utility model, the top of the mounting base is provided with a guide groove, and the slider is slidably disposed in the guide groove.

[0016] Beneficial effects

[0017] This utility model provides an auxiliary label-preheating device for a label-sleeving machine. It has the following beneficial effects:

[0018] 1. This label preheating auxiliary labeling device for a labeling machine, by rotating the adjusting screw, causes the adjusting nut to approach the stop block and compress the spring. The spring pushes the stop block, causing the sliding rod to slide on the top of the mounting base. The displacement of the sliding rod causes two guide rollers to move to one side of the heating sleeve. Under the compression of the two guide rollers, the label covers the outer circumference of the heating sleeve. This ensures both the tension adjustment of the label and the full adhesion between the label and the outer wall of the heating sleeve, thus guaranteeing the preheating effect.

[0019] 2. This label preheating auxiliary labeling device for a labeling machine allows adjustment of the spring preload by rotating an adjusting nut, which presses against a stop block. The adjusting nut, in conjunction with the rotating adjusting screw, adjusts the position of the adjusting nut, causing the spring to push the stop block and sliding rod to move. Two sliders at the bottom of the sliding rod slide within corresponding guide grooves. The position of the sliding rod is adjustable and can float within a certain range, providing adaptive adjustment of label tension. Attached Figure Description

[0026] A label preheating auxiliary labeling device for a labeling machine, such as Figure 1 and Figure 2 As shown, it includes:

[0027] Mounting base 10, with a heating rod 11 and a gasket 12 fixedly mounted on the top of the mounting base 10. A heating sleeve 13 is rotatably connected to the heating rod 11. A label is provided on one side of the gasket 12. By connecting the heating rod 11 to a power source, the heating rod 11 heats up and heats the heating sleeve 13. The strip-shaped rolled label is guided and preheated by the heating sleeve 13 and then affixed to the container, such as the outer surface of a bottle.

[0028] The heating sleeve 13 forms a cylindrical structure. The lower end of the heating sleeve 13 is rotatably connected to the gasket 12. The heating rod 11 is located inside the cavity of the gasket 12. The outer wall of the heating sleeve 13 is provided with anti-slip texture. The anti-slip texture can increase the contact force between the heating sleeve 13 and the label. When the label is released, it can push the heating sleeve 13 to rotate, thereby heating the label evenly and ensuring the preheating effect.

[0029] like Figure 2 , Figure 4 and Figure 5 As shown, a limiting structure is set on the mounting base 10 to press the label against the side wall of the heating sleeve 13. The limiting structure includes a guide roller 20, a sliding rod 21, and an adjusting screw 22. The sliding rod 21 is slidably set on the mounting base 10. Two rotatable guide rollers 20 are symmetrically arranged on the sliding rod 21. The adjusting screw 22 is threadedly connected to the mounting base 10 and can adjust the position of the sliding rod 21. The sliding rod 21 forms a rod with a horizontal cross section of U shape. The lower ends of the two guide rollers 20 are rotatably connected to the sliding rod 21. The two guide rollers 20 are symmetrically distributed about the heating rod 11 as the axis. The limiting structure also includes a slider 25. The slider 25 is fixedly installed at the bottom of the sliding rod 21. The sliding rod 21 is slidably connected to the mounting base 10 through the slider 25. A guide groove 14 is opened at the top of the mounting base 10, and the slider 25 is slidably set in the guide groove 14.

[0030] In this scheme, the adjusting screw 22 is rotated, which drives the adjusting nut 24 to approach the stop block 23 and compress the spring. The spring pushes the stop block 23, causing the sliding rod 21 to slide on the top of the mounting base 10. The displacement of the sliding rod 21 causes the two guide rollers 20 to move to one side of the heating sleeve 13. Under the compression of the two guide rollers 20, the label covers the outer circumference of the heating sleeve 13. This ensures both the tension adjustment of the label and the full adhesion between the label and the outer wall of the heating sleeve 13, thus ensuring the preheating effect.

[0031] like Figure 4 As shown, the limiting structure also includes a stop block 23 and an adjusting nut 24. The stop block 23 is fixedly connected to the sliding rod 21, and the adjusting nut 24 is threadedly connected to the adjusting screw 22. A spring is provided between the stop block 23 and the adjusting nut 24. The adjusting nut 24 can compress the spring to deform. The stop block 23 has a hole, and the adjusting screw 22 rotates through the hole, and the spring is sleeved on the adjusting screw 22.

[0032] By rotating the adjusting nut 24, the adjusting nut 24 is brought close to the stop block 23 and compresses the spring, so that the preload of the spring can be adjusted. In conjunction with the rotation of the adjusting screw 22, the position of the adjusting nut 24 is adjusted. The spring pushes the stop block 23 and the sliding rod 21 to move. The two sliders 25 at the bottom of the sliding rod 21 slide in the corresponding guide grooves 14. The position of the sliding rod 21 can be adjusted and can float within a certain range, which has the characteristic of adaptive adjustment of label tension.

[0033] The working principle of this utility model is as follows: By rotating the adjusting screw 22, the adjusting screw 22 moves the adjusting nut 24 closer to the stop block 23 and compresses the spring. Rotating the adjusting nut 24 again causes it to press against the stop block 23, thus adjusting the spring's preload. This adjustment, combined with the rotation of the adjusting screw 22, adjusts the position of the adjusting nut 24. The spring then pushes the stop block 23 and the sliding rod 21 to move. The two sliders 25 at the bottom of the sliding rod 21 slide within their corresponding guide grooves 14. The position of the sliding rod 21 can be adjusted and it can float within a certain range. The sliding rod 21 moves, causing the two guide rollers 20 to move to one side of the heating sleeve 13. Under the squeezing action of the two guide rollers 20, the label covers the outer circumference of the heating sleeve 13. This ensures both the tension adjustment of the label and the full adhesion between the label and the outer wall of the heating sleeve 13, thus ensuring the preheating effect. By connecting the heating rod 11 to the power source, the heating rod 11 heats the heating sleeve 13, and the strip-shaped rolled label is affixed to the container, such as the outer surface of a bottle, after being guided and preheated by the heating sleeve 13.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
