Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, and particularly relates to a horizontal quantitative traction mechanism for a label machine. Background Art

[0002] Labels are generally pasted on the outer packages of electronic products used in daily life as notes for displaying product parameters and anti-counterfeiting marks. In order to accurately, synchronously and orderly label a batch of products, automatic label machines are mostly used in current production lines for efficient labeling. However, in the labeling process of some small labels, the problem of unstable label feeding often occurs. Overfeeding will cause repeated labeling of a single product, and underfeeding will cause incomplete labeling of a single product. The reason is that the length and width dimensions of small labels are relatively small, and the feeding length of the labels is not accurately controlled when feeding the label tape.

[0003] There are many deficiencies in the traditional label tape pulling and traction mechanisms. Most of the adopted solutions are to use rubber rollers to squeeze and roll the label tape to provide the pulling force with static friction. However, there is often a problem of label tape slipping during pulling. Therefore, it is necessary for us to design a quantitative traction mechanism that can overcome the slipping of the label tape during pulling and whose theoretically electrically controlled rotation length is exactly the same as the length of the label tape being pulled, so as to help the automatic label machine achieve accurate and efficient labeling tasks. Summary of the Utility Model

[0004] The purpose of the utility model is to design and provide a horizontal quantitative traction mechanism for a label machine, which can overcome the slipping of the label tape during pulling and whose theoretically electrically controlled rotation length is exactly the same as the length of the label tape being pulled, so as to improve the dimensional control accuracy of the length of the remaining label tape being pulled and greatly improve the accuracy and efficiency of peeling the labels on the label tape.

[0005] The technical solution adopted to solve the above problems is as follows:

[0006] A horizontal quantitative traction mechanism for a label machine includes a traction motor, a transmission gear set, a driving gear roller and a driven gear roller that mesh and rotate with each other, a sliding feeding table and a top-pushing and clamping assembly.

[0007] The traction motor is arranged on a fixed seat, and the main shaft of the traction motor is connected to the transmission gear set. The transmission gear set transmits the rotational power to the driving gear roller.

[0008] The outer circumference of the driving gear roller is provided with active meshing teeth. The label tape to be pulled is clamped between the driving gear roller and the driven gear roller to stably, step by step and accurately pull and feed the material. The driving gear roller is matched with the fixed seat through a bearing seat.

[0009] The two sides of the passive gear roller are fitted with the shaft holes of the sliding feeding table, and the active gear roller is in horizontal external tangential contact with the passive gear roller to achieve meshing.

[0010] The two sides of the sliding feeding table are fitted with linear sliding grooves provided on the inner sides of the fixed seats to achieve horizontal linear sliding. A pushing block is provided in the middle of the lower side of the sliding feeding table. The pushing block is horizontally provided with a through hole, and the through hole is fitted with a tightening screw. Under the boost of the pushing and clamping assembly, a leftward pushing force on the sliding feeding table is always maintained. A pushing hook is provided on the right side of the sliding feeding table, and the pushing hook cooperates with the pushing and clamping assembly to achieve a rightward pushing and unloading force to separate the active gear roller and the passive gear roller, facilitating the threading of the remaining material of the label tape.

[0011] The pushing and clamping assembly includes a central shaft, an arc-shaped groove circumferentially provided on the fixed seat around the central shaft, a clamping rod, and a lever. The central shaft is fixedly mounted between the two fixed seats on both sides. The two ends of the clamping rod are arranged in the arc-shaped groove, and a lever is arranged between the clamping rod and the central shaft. The outer side of the lever can be manually pushed to the right to drive the clamping rod to slide within the arc-shaped groove, and the clamping rod pushes the pushing hook to the right to separate the active gear roller and the passive gear roller. Pushing to the left can drive the clamping rod to push the tightening screw to the left to achieve the external tangential meshing of the active gear roller and the passive gear roller.

[0012] Further, a material supporting plate is provided below the pushing block to prevent the remaining material of the label tape pulled down by traction from being wound reversely.

[0013] Further, a U-shaped limit clamping seat is provided on the fixed seat below the active gear roller.

[0014] Further, a spring is sleeved on the tightening screw to maintain the pre-tightening force for pushing the sliding feeding table to the left.

[0015] Further, a support rod is arranged between the two fixed seats on both sides to stabilize the mechanical structure of each component within the fixed seat.

[0016] The beneficial effects of the present utility model are as follows:

[0017] The horizontal quantitative traction mechanism for the label machine precisely drives a set of meshing gear rollers to rotate through the cooperation of a traction motor and gear transmission, and the two gear rollers precisely extrude and deform the remaining material of the label tape extruded in the middle and pull it out, improving the dimensional control accuracy of the pulled length of the label tape, and greatly improving the accuracy and efficiency of the peeling of the labels on the label tape.
