Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] like Figures 1 to 9 As shown, the prior art in this embodiment has the following problems: The inventors have found the following defects in the prior art: 1. After the labeling machine applies the label, it undergoes steam pre-shrinking treatment and then enters the steam furnace for shrinking treatment. In the pre-shrinking treatment stage, not only is steam wasted, but a fan is also needed to remove the excess steam, increasing energy consumption; 2. In the heat shrinking box, the steam heats and shrinks the plastic label by moving the cylinder up and down, which can lead to uneven heating of the plastic label, resulting in a lower product qualification rate; 3. After the heat shrinking box is filled with steam, condensate will adhere to the barrel opening, which will cause contamination if not treated in time.

[0030] Therefore, the inventor provides an energy-saving labeling machine for labeling bottled water bottles, including a conveyor belt device 1, a labeling device 2, and a label shrinking device. The labeling device 2 is located on the upper left side of the conveyor belt device 1, and the label shrinking device is located on the upper right side of the conveyor belt device 1. The label shrinking device further includes a fixing device 3, a steam label shrinking box 4, and a cleaning mechanism 5. The fixing device 3 is located below the labeling device 2, the steam label shrinking box 4 is located on the right side of the labeling device 2, and the cleaning mechanism 5 is located on the right side of the steam label shrinking box 4.

[0031] Using the above scheme, after the water bucket enters the labeling device 2 on the conveyor belt, the labeling device 2 places the plastic label on the bucket opening. After cutting the plastic label, the fixing device 3 automatically heats and shrinks the plastic label by one ring at an appropriate temperature to prevent the plastic label from falling off. This can replace the preheating box to fix the plastic label, preventing the label from shifting due to heat shrinkage. At the same time, it avoids the risk of damaging the bucket opening like hot air shrinking. After fixing the plastic label, the water bucket enters the steam shrinking box 4 along the conveyor belt 1. The sensor a17 on the steam shrinking box 4 detects the signal of the water bucket entering and completely shrinks the plastic label through the steam nozzle 16. The steam nozzle 16 can completely cover the plastic label at the bucket opening, completing the shrinking of the plastic label in one go, so that the plastic label is heated evenly during heat shrinking, ensuring the product qualification rate. After the plastic label shrinks, the water bucket comes to the cleaning mechanism 5. The sensor b23 detects the water bucket signal and automatically cleans the condensate on the water bucket opening to prevent the condensate from contaminating the bucket opening.

[0032] Further, the fixing device 3 further comprises a telescopic electric cylinder a6, a hollow rotating platform 7, a telescopic electric cylinder b8, a connecting rod 9, a connecting block 10, a sliding groove 11, and an electric heating assembly 12.

The telescopic electric cylinder b8 is arranged below the rear side of the hollow rotating platform 7. The connecting rod 9 is arranged below the telescopic electric cylinder b8. The connecting block 10 is rotatably connected to the connecting rod 9 on both sides of the connecting rod 9. The connecting rod 9 is rotatably connected to the hollow rotating platform 7 on the right side above the connecting rod 9. The sliding groove 11 is arranged on the front and rear sides of the connecting block 10 and fixed below the hollow rotating platform 7. The electric heating assembly 12 is arranged below the connecting block 10 and connected to the connecting block 10 through a rotating shaft. The rotating shaft between the electric heating assembly 12 and the connecting block 10 is slidably connected to the sliding groove 11.

[0033] When the sleeve label device 2 sleeves the plastic label on the bucket opening, the telescopic electric cylinder a6 is extended downward, so that the electric heating assembly 12 at the front end of the hollow rotating platform 7 is located at the side of the bucket opening with the plastic label. The telescopic electric cylinder b8 is retracted upward. The connecting block 10 is driven by the connecting rod 9 to rotate upward with the connecting block 10 and the hollow rotating platform 7 as the axis. The connecting block 10 drives the electric heating assembly 12 to retract inward on the sliding groove 11, so that the plastic label is pressed on the bucket opening. At the same time, the hollow rotating platform 7 drives the mechanism below to rotate, so that the electric heating assembly 12 below presses the plastic label on the side of the bucket opening. At the same time, the heat at the front end of the electric heating assembly 12 shrinks the plastic label. The plastic label is fixed on the bucket opening. The plastic label can be fixed by replacing the preheating box. The movement of the label is prevented, so that the plastic label is not offset due to the heat shrinkage. At the same time, there is no risk of damaging the bucket opening like the hot air shrinkage label. The structure of the air injection mechanism in the heat shrinkage box is improved. The plastic label is uniformly heated during heat shrinkage. The energy consumption is reduced while ensuring the product qualification rate.

[0034] Further, the connecting block 10 is arranged in a triangular structure.

[0035] The left side of the connecting block 10 is rotatably connected to the hollow rotating platform 7. The connecting block 10 is driven by the connecting rod 9 to rotate at the connecting position on the left side of the connecting block 10, so that the lower end of the connecting block 10 drives the electric heating assembly 12 to move upward and downward in an arc shape.

[0036] Further, the front end of the electric heating assembly 12 is arranged in a circular arc structure.

[0037] The circular arc structure can prevent the electric heating assembly 12 from damaging the plastic label when heating and shrinking the plastic label.

[0038] Further, the steam shrinkage box 4 further comprises a box body 13, a sliding table electric cylinder a 14, a steam hose 15, a steam nozzle 16, and a sensor a 17. The sliding table electric cylinder a 14 is arranged on the front and rear sides of the box body 13 respectively. The steam nozzle 16 is arranged in the box body 13 and connected with the output end of the sliding table electric cylinder a 14. The steam hose 15 is arranged between the box body 13 and the steam nozzle 16. The sensor a 17 is arranged on the top left side of the box body 13 and electrically connected with the workshop controller.

[0039] When the sensor a 17 detects the signal of the water bucket entering the box body 13, the sliding table electric cylinder a 14 drives the steam nozzle 16 to extend forward, so that the steam nozzle 16 holds the plastic label sleeve of the bucket opening, and the steam from the box body 13 enters the steam nozzle 16 through the steam hose 15 and is sprayed to the plastic label to make the plastic label shrink.

[0040] Further, the steam nozzle 16 further comprises an air inlet cavity 18 and a jet hole 19. The jet hole 19 is arranged on the rear side of the air inlet cavity 18.

[0041] The steam is uniformly dispersed into the jet hole 19 after entering the air inlet cavity through the steam hose 15.

[0042] Further, the height of the steam nozzle 16 is greater than the height of the plastic label on the water bucket.

[0043] The steam nozzle 16 can cover the plastic label on the bucket opening for one-time heat shrinkage. When the plastic label sleeve is heat shrunk, the bucket opening can be fully covered, so that the plastic label is uniformly heated during heat shrinkage, and the product qualification rate is ensured.

[0044] Further, the cleaning mechanism 5 further comprises a mounting seat 20, a sliding table electric cylinder b 21, a cleaning block 22, and a sensor b 23.

The cleaning block 22 is arranged on the rear side of the sliding table electric cylinder b 21 and connected with the output end of the sliding table electric cylinder. The sensor b 23 is arranged on the right side of the top end of the box body 13 and electrically connected with the workshop controller.

[0045] When the sensor b 23 detects that the water bucket has completed the shrinkage of the steam shrinkage box 4, the sliding table electric cylinder b 21 drives the cleaning block 22 to fold, and the condensate water on the bucket opening is absorbed and cleaned by the cleaning block 22. The cleaning block 22 can be made of soft sponge material, which can be folded and attached to the bucket opening while absorbing the condensate water on the surface of the bucket opening, so as to prevent the condensate water from polluting the bucket opening.
