Description

Technical Field

[0001] The invention relates to the technical field of labeling equipment, in particular to a labeling device for a finished product of an anti-rust cleaning agent. Background Art

[0002] The labeling machine is a device that uses adhesive to stick paper or metal foil labels on specified packaging containers. The production process of anti-rust cleaning agents in round bottles involves the labeling process. The specific process is that the round bottle contacts the conveyed label tape during rotation, and the part of the round bottle and the part of the label tape at the contact position approach each other and then displace, and then the edge of the label paper on the label tape is peeled off, the round bottle continues to rotate, and the label tape continues to be conveyed, and the peeled label paper is gradually attached to the round bottle, and the labeling work is completed in this way. Here, the viscosity of the adhesive between the label tape and the label paper will affect the difficulty of peeling the label paper. If it is a low temperature environment, the viscosity of the adhesive is high, and the label paper and the label tape are firmly bonded. , it is difficult to separate, and the label paper may be directly transported along with the label belt, that is, no labeling occurs. If it is a high temperature environment, although the label paper is easy to leave the label belt, it may be slightly displaced during the transportation of the label belt. In this way, after the label paper is affixed to the round bottle, it is not completely affixed to the specified position on the round bottle, thereby affecting the appearance of the product. Therefore, the label paper can be controlled to be heated again when it is about to be labeled, so that the adhesive melts to a certain extent, and the heated label paper is immediately affixed to the round bottle of the product. Based on the purpose of quickly positioning the heated label paper, the present invention provides a labeling device for a finished product of an anti-rust cleaning agent. Summary of the invention

[0032] refer to Figure 5 It is understood that the labeler 6 includes a device shell 12, a marking tape 14 that is slidably conveyed on the outer wall of the device shell 12, a guide roller 13 that cooperates with the device shell 12 to clamp the marking tape 14, and a fine roller 15 supported at one end of the device shell 12. The device shell 12 includes a V-shaped plate and fixed baffles at both ends of the V-shaped plate, and the fine roller 15 is distributed at the tip position of the device shell 12. The fine roller 15 is provided with convex shafts at both ends, and the convex shafts are movably sleeved in the through holes of the bracket fixed on the device shell 12. The conveyed marking tape 14 is padded between the fine roller 15 and the product round bottle 3 to transfer the mark on the marking tape 14 to the product round bottle 3. The outside of the device shell 12 is provided with a support plate to support the short shaft provided at the end of the guide roller 13.

[0033] refer to Figure 5 It is understood that the labeler 6 also includes a heating integration 10 arranged in the device shell 12, and a connecting shaft 11 for establishing a transmission between the heating integration 10 and the fine roller 15. The convex shaft of the fine roller 15 is meshed and connected with the bevel gear fixed on the connecting shaft 11 through a fixed bevel gear. The connecting shaft 11 is movably sleeved in the inner hole of the cylinder fixed on the device shell 12.

[0034] refer to Figure 7 It is understood that the heating integration 10 includes a heating part 16 for locally heating the identification tape 14 , a supply part 17 for supplying a hot air flow to the heating part 16 , and a braking part 18 for establishing transmission between the receiving shaft 11 and the supply part 17 .

[0035] refer to Figure 8 It is understood that the heating part 16 includes a square cover 23 in the shape of a square groove shell, a row of flat cylinder air nozzles 24 penetrating the bottom plate of the square cover 23, a reflux flat tube 19 fixedly connected to one end of the square cover 23, and an air supply square tube 22 fixedly connected to the row of flat cylinder air nozzles 24, the air supply square tube 22 is distributed on one side of the square cover 23, the square cover 23 is fixedly covered on a plurality of strip holes opened on one side of the V-shaped plate of the shell 12, and the flat cylinder air nozzle 24 locally heats the conveyed marking tape 14 by blowing air into the strip holes.

[0036] refer to Figure 8 It is understood that the heating part 16 also includes a U-shaped spring piece 20 and a valve plate 21. The valve plate 21 is sealed in a plate hole opened on the shell of one side of the air supply square tube 22. One end of the U-shaped spring piece 20 is fixed on the valve plate 21, and the other end is fixed on the air supply square tube 22. The valve plate 21 can swing under the action of air pressure. When the internal air pressure in the air supply square tube 22 is relatively high, the valve plate 21 swings outward on the air supply square tube 22 to release air and reduce pressure. Conversely, when the internal air pressure in the air supply square tube 22 is relatively low, the valve plate 21 can swing toward the inside of the air supply square tube 22, and the external air will be sucked into the air supply square tube 22. When the air supply square tube 22 is normally transporting hot air flow, that is, the air pressure in the air supply square tube 22 is within the specified range, the valve plate 21 does not swing.

[0037] The marking tape 14 conveyed through the holes of the shell 12 will be partially heated by the hot air, so that the adhesive between the tape body and the marking paper on the marking tape 14 will melt. Then the marking tape 14 will continue to be conveyed, and the marking tape 14 will bend and change direction at the fine roller 15, and then slide with the rotating product round bottle 3, and the marking paper will be uncovered by the rotating product round bottle 3, and then fall on the product round bottle 3, completing the labeling work.

[0038] The housing 12 is provided with a marking tape dispensing mechanism and a waste tape reeling mechanism after labeling is completed, which are used to control the conveying of the marking tape 14 . The marking tape 14 drives the fine roller 15 to rotate during conveying, and then drives the heating integration 10 through the connecting shaft 11 .

[0039] The supply part 17 includes a heating circular box 28, a heating wire coil 26 for heating distributed in the heating circular box 28, a fan 25 for conveying ventilation, and a fan shaft 27 for fixedly supporting the fan 25. The fan shaft 27 is movably sleeved in a through hole opened on the bottom plate at one end of the heating circular box 28. The other end of the heating circular box 28 is fixedly connected to the reflux flat tube 19 by setting a neck tube. One end of the air supply square tube 22 passes through the side shell of the heating circular box 28. The fan 25 rotates to make the air flow pass through the heating wire coil 26 and then be discharged through the air supply square tube 22.

[0040] The braking part 18 includes a limit frame 30 fixed on the housing 12, and a constant speed group 29 and an adjustment group 31 supported on the limit frame 30. One end of the constant speed group 29 is vertically transmitted to the connecting shaft 11, and the adjustment group 31 establishes transmission between the constant speed group 29 and the fan shaft 27.

[0041] The speed control group 29 includes a tail shaft 32, a tail plate 33 fixed at one end of the tail shaft 32, a plurality of direction rods 34 evenly arranged on the tail plate 33, a spring 35 sleeved on the direction rods 34, and a flat plate 36 fixedly connected to all the direction rods 34. The other end of the tail shaft 32 is meshed and driven with a bevel gear fixed at the end of the guide shaft 11 through a fixed bevel gear. The direction rod 34 slides through a through hole opened in the tail plate 33. The spring 35 is supported between the tail plate 33 and the flat plate 36. The tail shaft 32 is movably sleeved in a column hole opened in the limit frame 30.

[0042] The adjustment group 31 includes a rubber ring tube 38 that is in vertical contact with the flat plate 36, a double-control shaft 39 vertically fixed in the middle of the rubber ring tube 38, a limit moving block 40 vertically connected to one end of the double-control shaft 39, a threaded column 41 for pushing the limit moving block 40, and a worm 37 distributed in parallel on one side of the double-control shaft 39. The double-control shaft 39 is meshed and driven with a long-cylinder gear fixed at one end of the worm 37 through a fixed short-cylinder gear. The double-control shaft 39 and the threaded column 41 are respectively movably sleeved in two through holes opened on the limit moving block 40, and a local section on the limit frame 30 slides through the square hole opened on the limit moving block 40. The threaded column 41 penetrates the threaded hole opened on the limit frame 30. The worm 37 is movably sleeved in the through hole opened on the limit frame 30, and the end of the fan shaft 27 is meshed and driven with the helical teeth on the fixed gear and the worm 37.

[0043] refer to Fig.13It is understood that the rotating threaded column 41 can be pre-adjusted to make the limit wandering block 40 translate, and then the rubber ring cylinder 38 can be translated by the axial movement of the double control shaft 39 to change the contact point between the rubber ring cylinder 38 and the flat plate 36. The rotation speed of the flat plate 36 remains unchanged. The closer the rubber ring cylinder 38 is to the edge of the flat plate 36, the higher the rotation speed of the rubber ring cylinder 38 will be. Conversely, the closer it is to the middle of the flat plate 36, the lower the rotation speed of the rubber ring cylinder 38 will be. The rotation speed of the rubber ring cylinder 38 affects the subsequent air flow velocity. The faster the hot air flow blows onto the identification tape 14, the faster the identification adhesive on the identification tape 14 melts.

[0044] The continuous rotation of the guide shaft 11 drives the tail shaft 32 to rotate, the tail plate 33 continues to rotate, and then drives the flat plate 36 to rotate through the direction rod 34, and then drives the rubber ring tube 38 to rotate, and then drives the fan shaft 27 through the worm 37. The fan shaft 27 and the fan 25 rotate synchronously, causing the airflow in the heating round box 28 to flow in a directional manner, and the airflow blows through the electric heating wire disc 26 that is powered and heated. Here, the electric heating wire disc 26 is a prior art structure. The electric heating wire disc 26 heats the air passing through it, and the generated hot air flow is discharged through the air supply square tube 22, and then blown out through a row of flat cylinder air nozzles 24. The hot air flow impacts the conveying identification belt 14, and the return flat tube 19 is used to recover the air in the square cover 23. The airflow returns to the heating round box 28 through the return flat tube 19, and is heated by the electric heating wire disc 26 after continuing to flow. In this way, the airflow is recycled to improve the energy saving of the equipment.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
