Description

Technical Field

[0001] The utility model relates to the technical field of labeling machine equipment, in particular to a label tape conveying mechanism of a labeling machine. Background Art

[0002] With the continuous innovation of science and technology, the application of production automation has gradually replaced traditional manual labor. In traditional labor-intensive manufacturing industries, the application of automation is more needed. In the current production process of label stickers, labels containing product information are attached to products and sold along with the products. This method of hanging label products is also applied in the clothing industry. When making this label sticker, a label paper containing information such as products is pasted on the hanging label sticker.

[0003] Traditionally, it is generally manual to paste the label paper onto a specific position of the label sticker. With the development of the economy, it has now developed into a semi-automatic or fully automatic labeling pattern, and a labeling machine can be used to label different items.

[0004] The round bottle labeling machine is suitable for labeling round bottles such as plastic bottles, metal bottles, and glass bottles. The round bottle labeling machine includes a horizontal labeling machine and a semi-automatic labeling machine. Among them, the horizontal labeling machine is suitable for labeling a large number of round bottles. The round bottles are conveyed to the labeling mechanism by a conveyor belt, then labeled, and finally collected.

[0005] However, in the existing round bottle labeling machines, two adjacent pressure rollers are used to flatten the label tape during transportation. However, when flattening the label tape with large wrinkles, this technical solution will produce the effect of folding the wrinkled position instead of flattening it. Summary of the Utility Model

[0006] Purpose of the Utility Model:

[0007] In order to overcome the problems existing in the prior art, the utility model provides a label tape conveying mechanism of a labeling machine, which flattens the label tape during transportation by arranging two flattening rollers, avoiding the problem of unstable label separation caused by wrinkles in the label tape when it reaches the label separation board.

[0008] To solve the above problems, the utility model adopts the following technical solutions:

[0009] A label tape conveying mechanism of a labeling machine includes a mounting base. Along the label tape conveying direction, a unwind roller, a flattening roller, a label separation board, and a winding roller are sequentially arranged at the upper end of the mounting base; a plurality of conveying rollers are also arranged between the unwind roller and the winding roller. There are two flattening rollers, and the flattening roller includes an inward concave spiral groove extending from the middle to both ends. The rotation direction of the inward concave spiral groove from the middle to both ends of the flattening roller is the same as the rotation direction of the flattening roller when conveying the label tape.

[0010] Preferably, two flattening rollers are arranged close to each other. One of the flattening rollers close to the label dividing board is rotatably arranged on the fixed seat, and the other flattening roller is slidably arranged on the moving seat through a slider and is rotatably connected to the slider through a bearing. At the same time, a tension adjustment knob is provided to fix its position on the moving seat.

[0011] Preferably, both of the two flattening rollers are provided with rotating shafts extending downward. The rotating shafts of the two flattening rollers are provided with gears that mesh with each other when in interference fit.

[0012] Preferably, both the fixed seat and the moving seat are arranged on a lifting seat on the mounting seat. The lifting seat is arranged on the mounting seat and is connected to the mounting seat through a threaded rod.

[0013] Preferably, the unwinding roller and the winding roller are arranged at one end of the mounting seat, and the label dividing board is arranged at the other end of the mounting seat.

[0023] All features disclosed in this specification, or steps in all methods or processes disclosed, can be combined in any way, except for mutually exclusive features and / or steps.

[0024] Any feature disclosed in this specification (including any additional claims, abstract, and drawings), unless specifically stated, can be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.

[0025] To make the above-mentioned objects, features, and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings.

[0026] As Figures 1-4 shown, a label tape conveying mechanism of a labeling machine includes a mounting base. Along the label tape conveying direction, a unwind roller 2, a flattening roller 6, a label separating plate 3, and a winding roller 4 are sequentially arranged at the upper end of the mounting base. A plurality of conveying rollers 5 are further arranged between the unwind roller 2 and the winding roller 4. There are two flattening rollers 6. The flattening roller 6 includes an inward concave spiral groove extending from the middle to both ends. The rotation direction of the inward concave spiral groove from the middle to both ends of the flattening roller is the same as the rotation direction of the flattening roller 6 when conveying the label. During the conveying process, the label passes through the two flattening rollers 6 in an S shape. The label tape first passes through one of the flattening rollers for preliminary flattening and wrinkling placement. When it reaches between the two flattening rollers, it is folded under the action of a pressing force. After the preliminary flattening is completed, it reaches the middle of the two flattening rollers for further flattening. By setting two flattening rollers to flatten the conveying label tape, the problem that the label tape is unstable during label separation due to wrinkles when reaching the label separating plate is avoided.

[0027] In this embodiment, two flattening rollers 6 are arranged close to each other. One of the flattening rollers 6 close to the label separating plate 3 is rotatably arranged on a fixed seat 11, and the other flattening roller 6 is slidably arranged on a moving seat 12 through a slider and is rotatably connected to the slider through a bearing. At the same time, a tension adjustment knob for fixing its position on the moving seat is provided. With this structure, the distance between the two flattening rollers can be adjusted to avoid the situation of being too large or too small. Generally, it is sufficient to make the two flattening rollers have an interference fit with the label tape between them at the same time.

[0028] In this embodiment, the two flattening rollers 6 both extend downward with a rotating shaft 8. The rotating shafts 8 of the two flattening rollers are provided with gears 9 that mesh with each other during their interference fit. With this structure, the two flattening rollers can rotate synchronously, improving stability.

[0029] In this embodiment, the fixed seat 11 and the moving seat 12 are both arranged on the lifting seat 13 on the mounting seat. The lifting seat 13 is arranged on the mounting seat and connected to the mounting seat through a threaded rod 14. With this structure, the height of the fixed seat 11 and the moving seat 12 can be adjusted by rotating the threaded rod 14. The sub-label board can be selectively installed on the lifting seat to synchronously adjust the height with the flattening roller, or can be directly fixed on the mounting seat. With this structure, it is convenient to center the flattening roller and the label tape, so that the label tape is positioned in the middle of the flattening roller.

[0030] In this embodiment, the unwinding roller 2 and the winding roller 4 are arranged at one end of the mounting seat, and the sub-label board 3 is arranged at the other end of the mounting seat.

[0031] In this embodiment, the mounting seat is further provided with a tensioning roller 7.

[0032] In this embodiment, the mounting seat is further connected with a position adjusting mechanism 10. The position adjusting mechanism 10 includes a transverse moving mechanism and a longitudinal moving mechanism that are driven and moved through a lead screw and a guide rod. By rotating the lead screw, the mounting seat threadedly connected thereto is driven to move. This is a relatively common technical means in the prior art and will not be elaborated here.

[0033] The purpose of the above embodiments is to exemplarily reproduce and deduce the technical solutions of the present invention, and to completely describe the technical solutions, purposes and effects of the present invention. The purpose is to make the public understand the disclosed content of the present invention more thoroughly and comprehensively, and does not limit the protection scope of the present invention hereby.

[0034] The above embodiments are not exhaustive listings based on the present invention. In addition, there may be multiple other embodiments not listed. Any replacement and improvement made without violating the concept of the present invention fall within the protection scope of the present invention.
