Description

Technical Field

[0001] The utility model belongs to the technical field of labeling equipment, in particular to a labeling machine. Background Art

[0002] Labeling machines are automated packaging equipment used to attach labels to product packaging. Labeling machines are widely used in food, medicine, cosmetics, daily chemicals, electronics, hardware, plastics and other industries. Labeling machines play an important role in modern packaging production lines with their efficient, accurate and flexible labeling capabilities.

[0003] The existing labeling machine consists of the following structures: unwinding wheel, guide roller, conveying mechanism, rewinding wheel, labeling roller, sensor, etc. The working principle is: when the product reaches the position of the labeling machine, the sensor will detect the product and the labeling machine will automatically put down a label from the roll of labels and accurately stick the label on the specified position of the product.

[0004] At present, the labeling machine in the prior art has the following disadvantages: the retaining ring for limiting the label paper tape is directly mounted on the roller of the labeling machine without a fixed structure. The labeling machine vibrates during operation, and the position of the retaining ring will shift over time, causing the label paper tape to shift, seriously affecting the accuracy of the subsequent label pasting position. Alternatively, some retaining rings are fixed with screws. Due to the large number of rollers, this fixing method is relatively cumbersome and complicated, which increases labor and affects work efficiency. Therefore, a labeling machine is proposed to address the above problems. Utility Model Content

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Specific examples are given below.

[0022] See also Figure 1-Figure 3The labeling machine of the present invention comprises a labeling machine chassis 1, on which a conveying mechanism 2 for conveying products is mounted, a controller 3 is fixedly mounted on the labeling machine chassis 1, and a paper tape conveying mechanism 4 for conveying label paper tape, the paper tape conveying mechanism 4 comprises a reel 401, a reel 402, and a roller mechanism 403 for transferring the label paper tape between the unwinding wheel 401 and the rewinding wheel 402, the roller mechanism 403 comprises a plurality of rollers 4031, and the roller 4031 is movably provided with a C The two ends of the C-shaped positioning retaining ring 5 are respectively fixed with a first fixing ear 6 and a second fixing ear 7. The first fixing ear 6 is fixed with a connecting rod 8. The top of the connecting rod 8 slides through the hole opened on the second fixing ear 7 and extends to the top of the second fixing ear 7. The top of the connecting rod 8 is eccentrically rotated by the rotating rod to provide a cam 9 for fixing the positioning retaining ring. One side of the cam 9 is fixed with an operating handle 10. When working, when the staff starts the labeling machine, it is necessary to adjust the labeling machine according to different labels. When the label is pasted on the product, the position of the C-shaped positioning retaining ring 5 on the roller 4031 is adjusted accordingly. First, the staff slides the two C-shaped positioning retaining rings 5 so that the two move to the corresponding positions. Then, the staff needs to fix the C-shaped positioning retaining ring 5 and presses the operating handle 10 to drive the cam 9 to rotate. Due to the squeezing of the second fixing ear 7 by the protruding position of the cam 9, the second fixing ear 7 is close to the first fixing ear 6. At the same time, the C-shaped positioning retaining ring 5 begins to retract and clamps the roller 4031 to fix the position of the C-shaped positioning retaining ring 5. On the contrary, when it is necessary to open the C-shaped positioning retaining ring 5 to adjust its position, due to the structural characteristics of the C-shaped positioning retaining ring 5, it has a certain elasticity. The operating handle 10 is pulled in the opposite direction to open the C-shaped positioning retaining ring 5. The principle is consistent with the above and will not be repeated here. Through the design and coordination of the above structure, the C-shaped positioning retaining ring 5 will not be affected by the vibration of the equipment, thereby causing the label paper tape to be displaced and affecting the accuracy of subsequent label pasting. At the same time, the fixing structure is convenient to use and the fixing method is convenient, which greatly improves the work efficiency.

[0023] Furthermore, one side of the first fixing ear 6 and the second fixing ear 7 is provided with a receiving groove 11 that cooperates with the operating handle 10, and triangular teeth 12 are fixedly provided on the opposite surfaces of the inner wall of the receiving groove 11. The angle of the triangular teeth 12 is set as an arc chamfer. During operation, when the C-shaped positioning ring 5 is fixed, the operating handle 10 is pulled and pressed into the receiving groove 11, and its edge squeezes the triangular teeth 12, and the receiving groove 11 is squeezed and slightly deformed. After the operating handle 10 continues to enter the receiving groove 11, the triangular teeth 12 rebound and clamp the operating handle 10 to fix it. Moreover, since the angle of the triangular teeth 12 is an arc chamfer, the operating handle 10 is easier to enter the receiving groove 11.

[0024] Furthermore, a scale 13 is provided on the circumferential surface of the roller 4031. During operation, when the staff adjusts the position of the C-shaped positioning retaining ring 5, the scale 13 on the roller 4031 can facilitate the staff to accurately control the position and spacing of the two C-shaped positioning retaining rings 5, making it more convenient to use.
