DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] like Figures 1 to 5 As shown, a bottle pressing main rod for a labeling machine comprises a main rod 6 and two auxiliary rods 3. The outer walls of the main rod 6 and the auxiliary rod 3 are connected with a bracket 1. The bracket 1 is U-shaped. A total of five mounting holes are opened on the two horizontal plates of the bracket 1. The upper end of the main rod 6 and the two ends of the two auxiliary rods 3 are penetrated in the mounting holes. The top of the main rod 6 is fixedly connected to the top surface of the bracket 1 by bolts. The tops of the two auxiliary rods 3 are penetrated with a cushion block 9 located above the bracket 1. The outer side of the top of the auxiliary rod 3 is threadedly connected with a nut 15, and the bottom surface of the nut 15 is against the top surface of the cushion block 9. Two spring positioning rings 5 ​​are sleeved on the outer side of the main rod 6, and two main springs 14 sleeved on the outer side of the main rod 6 are connected between the two spring positioning rings 5. A spring connecting ring 7 sleeved on the outer side of the main rod 6 is connected between the two main springs 14. Two spring positioning rings 5 ​​are sleeved on the outer side of the auxiliary rod 3, and an auxiliary spring 13 sleeved on the outer side of the auxiliary rod 3 is connected between the two spring positioning rings 5. A bottle pressing head 18 is connected to the bottom of the main rod 6.

[0023] like Figures 1 to 6 As shown, when the bottle pressing main rod for the labeling machine in the utility model is in use, the original L-shaped bracket 1 is changed into a U-shaped frame, and the main rod 6 and the two sub-rods 3 are passed through the mounting holes, and the sub-rods 3 are passed through the mounting holes and the assembly holes of the equipment, and finally assembled and connected through the nuts 15 on the cushion blocks 9, and the top of the main rod 6 is assembled and connected with the bracket 1 by bolts, which can make the assembly of the main rod 6 and the sub-rod 3 simple and convenient for disassembly and assembly during later maintenance. The overall appearance of the main rod 6 and the sub-rod 3 can be hard chrome plated with an HV of 1000 or more, thereby improving the overall wear resistance of the main rod 6 and the sub-rod 3.

[0024] like Figure 1 As shown, each mounting hole is provided with a main rod wear-resistant sleeve 2 and a secondary rod wear-resistant sleeve 4 which are sleeved on the outside of the main rod 6 and the secondary rod 3. The main rod wear-resistant sleeve 2 and the secondary rod wear-resistant sleeve 4 are both located on the outside of the main rod 6 and the secondary rod 3, and are sleeved on the outside of the spring positioning ring 5.

[0025] Specifically, by sleeved the main rod wear-resistant sleeve 2 and the auxiliary rod wear-resistant sleeve 4 on the outside of the main rod 6 and the auxiliary rod 3, the wear resistance of the main rod 6 and the auxiliary rod 3 can be improved and the service life can be extended.

[0026] like Figure 1 As shown, a fixed shaft is connected to the back of the bracket 1, a roller 10 is connected to the outside of the fixed shaft, a hexagonal bolt 16 is threadedly connected to the outer end of the roller 10, the end of the hexagonal bolt 16 is threadedly connected to the fixed shaft, and an annular pad 17 is sleeved on the outside of the hexagonal bolt 16.

[0027] Specifically, the roller 10 can be fixed to the back of the bracket 1 by connecting the hexagonal bolt 16 and the annular washer 17 with the fixed shaft, so that the roller 10 is conveniently connected to the downward pressing guide rail.

[0028] like Figure 1 As shown, both the main rod 6 and the auxiliary rod 3 are provided with a clamping groove on the outside, and a clamping spring 12 is embedded in the clamping groove.

[0029] Specifically, the spring assembly on the main rod 6 and the auxiliary rod 3 can be limited by the engagement of the clamping spring 12 with the clamping groove, so that the main rod 6 and the auxiliary rod 3 can be conveniently disassembled.

[0030] like Figure 1 , Figure 2 and Figure 6 As shown, a bead 22 is clamped inside the bottle pressing head 18, the bottle pressing head 18 is sleeved on the outside of the bottom of the main rod 6, and a clamping ring 20 is sleeved on the outside of the bottle pressing head 18, a pin 19 is inserted in the clamping ring 20, the pin 19 is inserted into the main rod 6, and a seesaw 21 is connected to the inner side of the clamping ring 20, and the seesaw 21 is located on the outer wall of the bottle pressing head 18.

[0031] Specifically, when the bottle pressing head 18 is in contact with the bottle and under pressure for a long time, the bell mouth of the bottle pressing head 18 can be just engaged with the bottle. By utilizing the cooperation of the seesaw 21, the pin 19 and the clamping ring 20, the bottle pressing head 18 can be more conveniently connected to the lower end of the main rod 6, and by pressing the seesaw 21, the pin 19 and the bottle pressing head 18 on the main rod 6 can be separated, so as to facilitate the quick replacement of the bottle pressing head 18.

[0032] The bottle pressing head 18 can be an injection-molded part, and the material has relatively increased wear resistance and rigidity, thereby increasing the service life of the bottle pressing head 18 .

[0033] like Figure 1 and Figure 3 As shown, the bottom end of the main rod 6 is connected with a main rod wear-resistant screw 8 , and the main rod wear-resistant screw 8 is in contact with the outer wall of the bead 22 .

[0034] Specifically, when the bottle pressing head 18 follows the up and down movement of the main rod 6, the bead 22 in the bottle pressing head 18 will always be in contact with the main rod wear-resistant screw 8. By utilizing the setting of the main rod wear-resistant screw 8 and the bead 22, the bottom of the main rod 6 can be subjected to force through the main rod wear-resistant screw 8 and the bead 22, thereby further improving the wear resistance and heat resistance of the bottle pressing head 18 and the main rod 6, and further enhancing the service life.

[0035] like Figure 1 As shown, the outer wall of the main rod 6 is sleeved with a gasket 11. The arrangement of the gasket 11 can increase the buffer force for the movement of the main rod 6 and the auxiliary rod 3, improve stability and reduce noise.

[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
