Description

Technical Field

[0001] This utility model relates to the field of machinery, and in particular to a bottle labeling machine, specifically a push-top mechanism for a bottle labeling machine with easily adjustable roller distance. Background Technology

[0002] In the beverage production and packaging industry, after beverages are filled into bottles and capped, they need to be labeled. A commonly used extrusion bottle labeling machine utilizes a conveyor belt to transport bottles. Pushing mechanisms and traction rollers are installed on both sides of the conveyor belt. The traction rollers are connected to the label conveyor line. When a bottle moves to the labeling area, the pushing mechanism uses a cylinder to move two rollers, whose axes are parallel to the bottle's axis, towards the opposite traction roller. This makes the rollers tangential to the bottle and pushes the bottle into contact with the label on the traction roller surface. As the traction roller rotates the bottle, the label on the traction roller adheres smoothly to the bottle.

[0003] The distance between the two rollers needs to be adjusted to accommodate bottles of different diameters. However, the existing adjustment method requires disassembling the bolts of the roller mounting bracket, determining the distance, and then retightening the bolts. This is inconvenient, has poor adjustment accuracy, and may result in the two rollers becoming misaligned, rendering the device unusable. Furthermore, the height of the pushing mechanism also needs adjustment to accommodate bottles of different heights, but the existing adjustment method is similarly inconvenient. Therefore, an improved technology is urgently needed to solve the aforementioned problems in the existing technology. Utility Model Content

The first limiting ring 17 abuts against the inner surface of the end plate 9. The first limiting ring 17 ensures that the bidirectional lead screw 10 will not loosen axially, further ensuring the stability of the bidirectional lead screw 10. A square head 18 is provided at one end of the bidirectional lead screw 10 located on the outer side of the end plate 9, so as to facilitate the rotation of the bidirectional lead screw 10 by tools such as wrenches, or auxiliary tools such as handles or handwheels can be installed. There are two U-shaped moving frames 5, and each U-shaped moving frame 5 is provided with a roller 6 at its outer end. The axis of the roller 6 is perpendicular to the bidirectional lead screw.

[0020] Guide sleeves 19 are provided on both sides of the lifting seat 1 along the vertical direction. A second screw nut 20 is provided in the middle of the lifting seat 1 along the vertical direction. The lifting seat 1 is movably connected to two columns 21 through the guide sleeves 19. The top of the column 21 is connected to a top plate 22, and the bottom of the column 21 is connected to a base 23. The top plate 22 is also connected to a longitudinal screw 24.

[0021] Installation method and operating principle: Connect cylinder 2 to the side of lifting seat 1. Then, fasten the fixed seat 4 to the connecting plate 3 on the piston rod of cylinder 2 with bolts. Next, install roller 6 on the outer end of U-shaped moving frame 5. Then, connect the two U-shaped moving frames 5 to the left thread 11 and right thread 12 of the double-acting screw 10 respectively through their first screw nut 15. Then, place the double-acting screw 10 into the transverse groove 7 of the fixed seat 4. The inner end of the double-acting screw 10 is connected to the screw seat 16, and the outer end is fitted with a first limiting ring 17 and fastened with bolts. Then, pass the outer end of the double-acting screw 10 through the end plate 9 and install the end plate 9 on the open side of the transverse groove 7 of the fixed seat 4 with bolts. At this time, the first limiting ring 17 abuts against the inner side of the end plate 9, the fixing block 13 of the U-shaped moving frame 5 is located in the transverse groove 7, and the guide block 14 is located in the guide groove 8 of the fixed seat 4. Rotate the bidirectional lead screw 10 to bring the two U-shaped moving frames 5 closer together, then reverse the bidirectional lead screw 10 to move the two U-shaped moving frames 5 to opposite ends at the same speed. Finally, connect the lifting seat 1 to the column 21 via the guide sleeve 19, then connect the top of the column 21 to the top plate 22. Pass the longitudinal lead screw 24 through the top plate 22, and put the second limiting ring 26 on the longitudinal lead screw 24. Then pass the longitudinal lead screw 24 through the second lead screw nut of the lifting seat 1 until the handwheel 25 abuts against the upper surface of the top plate 22. Next, move the second limiting ring 26 to the corresponding position and fasten it to the longitudinal lead screw 24 with bolts. At this time, the second limiting ring 26 abuts against the lower surface of the top plate 22, completing the installation. Before use, the base 23 is installed on the conveyor belt side of the labeling machine via the connecting bracket. In use, depending on the bottle diameter, use a wrench or other tools, or install a handle or handwheel on the square head 18, to rotate the bidirectional screw 10. This causes the two U-shaped moving frames 5 to move closer or further apart, thereby adjusting the distance between the two rollers 6 to better fit different bottles. The piston rod of the cylinder 2 extends, pressing the roller 6 against one side of the bottle. On the other side of the bottle, the label is affixed to the bottle surface through the cooperation of the traction roller and the label take-up roller. This utility model has a reasonable structure. A fixing seat 4 is provided on the outer side of the connecting plate 3 of the cylinder 2. The fixing seat 4 has a transverse groove 7 for installing the bidirectional screw 10. The fixing seats 4 on the rear side of the two U-shaped moving frames 5 are respectively provided with first screw nuts 15 with opposite threads to cooperate with the left thread 11 and right thread 12 of the bidirectional screw 10. When the bidirectional screw 10 is rotated, the two U-shaped moving frames 5 move closer or further apart, thereby quickly adjusting the distance between the two rollers 6 according to the bottle diameter. The adjustment method is simpler and more efficient, with higher adjustment accuracy, and it will not result in the two rollers 6 being out of parallel.
