Abstract

A bottle-fixing device. The bottle-fixing device comprises a bottle-pressing turntable (1), wherein bottle-pressing mechanisms (2) are provided on the bottle-pressing turntable at intervals. Each bottle-pressing mechanism comprises an outer bottle-pressing unit (3) and an inner bottle-pressing unit (4), wherein the outer bottle-pressing unit comprises an outer driving portion (5) and an outer bottle-pressing head (6); the inner bottle-pressing unit comprises an inner driving portion (7) and an inner bottle-pressing head (8); the inner bottle-pressing head is adapted to a bottle mouth of a bottle (9) to be packaged; the outer bottle-pressing head is cylindrical, and the diameter of the outer bottle-pressing head is adapted to the body of said bottle; and the inner bottle-pressing head is arranged inside the outer bottle-pressing head and is in clearance fit with the outer bottle-pressing head. When said bottle and the bottle-pressing turntable synchronously rotate, the inner driving portion drives the inner bottle-pressing head to press the bottle mouth of said bottle downwards, and the outer driving portion drives the outer bottle-pressing head to abut against the top of the body of said bottle downwards, such that label paper on the outer side of the neck of said bottle is supported by means of the outer bottle-pressing head in a labeling process so as to ensure firm pasting, thereby guaranteeing a subsequent modeling effect.

Description

Bottle fixing device Technical Field

[0001] The present invention relates to the technical field of labeling machines, in particular to a bottle fixing device. Background Art

[0002] At present, some customers require full-body labeling on the entire bottle. The height of the label paper used for the full-body label is the distance from the bottle mouth to the bottom of the bottle. When labeling, first spray hot melt glue on the bottle body. After spraying, the bottle continues to rotate and moves forward to the labeling station. The glue spraying position on the bottle body first contacts and fits with the front side of the label paper in the labeling station. After that, the label paper is wrapped and pasted on the bottle while the bottle rotates. During the wrapping process, the labeling station will brush glue on the back side of the label paper at the same time, so that the front side of the label paper after wrapping is firmly adhered to the bottle body, and the back side of the label paper is overlapped and pasted. On the front side, the label paper is finally formed so that it is tightly attached to the bottle body and the outer part of the bottleneck is in the shape of a paper tube; after the label paper is pasted, the packaging bottle continues to rotate and rolls forward over the brush, and the brush deforms the label paper on the outer side of the bottleneck and then fits on the bottleneck. The overall effect is shown in Figure 8, and the full-body labeling process is completed; however, in the actual labeling process, it was found that due to the thin bottleneck, the label paper on the outer side of the bottleneck was in a suspended state, resulting in poor adhesion between the front and back sides of the label paper here, which in turn caused the glue to come off when the label paper was subsequently shaped by the brush, affecting the molding effect. Summary of the Invention

[0003] In view of the above problems, an embodiment of the present invention provides a bottle positioning device.

[0005] During the rotation of the bottle pressing turntable, the external driving part drives the external pressure bottle head to move up and down periodically, and the internal driving part drives the internal pressure bottle head to move up and down periodically, thereby completing: after the packaging bottle enters the bottom of the bottle pressing turntable from the bottle feeding position, the internal pressure bottle head moves downward and presses the bottle mouth tightly; before the packaging bottle moves to the labeling station position, the external pressure bottle head moves downward and is coaxially sleeved on the outer periphery of the bottle neck in a way that the bottom contacts the top of the bottle body; after the full body label is pasted, the external pressure bottle head moves upward and resets; and finally, before the packaging bottle is sent out from the bottle discharging position, the internal pressure bottle head moves upward and resets.

[0025] During the rotation of the bottle pressing turntable 1, the external driving part 5 drives the external bottle pressing head 6 to move up and down periodically, and the internal driving part 7 drives the internal bottle pressing head 8 to move up and down periodically, thereby completing the following: after the packaging bottle 9 enters the bottom of the bottle pressing turntable 1 from the bottle feeding position, the internal bottle pressing head 8 moves downward to press the bottle mouth of the packaging bottle 9; before the packaging bottle 9 moves to the labeling station position, the external bottle pressing head 6 moves downward to be coaxially sleeved on the outer periphery of the bottle neck in a way that the bottom contacts the top of the bottle body; after the full body label is pasted, the external bottle pressing head 6 moves upward to reset; and finally, before the packaging bottle 9 is sent out from the bottle discharging position, the internal bottle pressing head 8 moves upward to reset.

[0026] During implementation, the bottle feeding and discharging of the bottle fixing device are completed by the bottle feeding star wheel and the bottle discharging star wheel on the center guide plate. A bottle supporting mechanism is set under each bottle pressing mechanism 2, and the bottle supporting mechanism will rotate synchronously with the bottle pressing turntable 1. Each packaging bottle 9 will be sent into a bottle supporting mechanism by the bottle feeding star wheel. The center guide plate, bottle feeding star wheel, bottle discharging star wheel and bottle supporting mechanism are all existing equipment, and the specific structure will not be repeated here.

[0027] During implementation, a cam plate 10 is provided above the bottle pressing turntable 1.

During the rotation, the inner cam 13 first reaches point A, and thereafter the inner cam track 14 begins to press the inner cam 13 downward, and the inner cam 13 drives the inner pressure bottle head 8 downward to press tightly against the bottle mouth of the bottle 9, and the bottle 9 continues to rotate with the bottle pressing turntable 1; when the outer cam 11 moves to the outer When the cam track 12 is at point C, the outer cam track 12 starts to press the outer cam 11 downward, and the outer cam 11 drives the external pressure bottle head 6 downward to press it tightly against the top of the bottle body; after the inner and outer pressure bottle heads are pressed tightly, the packaging bottle 9 starts to enter the labeling station area for labeling. During the labeling process, due to the supporting effect of the external pressure bottle head 6, the overlapping part of the rear side and the front side of the label paper is firmly pasted. After the whole body label is pasted, when the outer cam 11 moves to point D of the outer cam track 12, the outer cam 11 starts to move upward and simultaneously drives the external pressure bottle head 6 to reset upward. Thereafter, when the inner cam 13 moves to point B of the inner cam track 14, the inner cam 13 starts to move upward and simultaneously drives the internal pressure bottle head 8 to reset upward. Finally, the labeled packaging bottle 9 is sent out through the bottle discharge star wheel in the center guide plate.

[0034] In specific implementation, the inner cam 13 and the outer cam 11 are fixed on the side surfaces of the corresponding sliding seat 20, the inner sliding rod 15 and the outer sliding rod 17 are fixed to the corresponding sliding seat 20, and the two ends of the return spring 21 are respectively connected to the locking bolt 22 and the upper side surface of the sliding seat 20. Under the action of the inner cam 13 or the outer cam 11, the sliding seat 20 moves downward, driving the corresponding inner sliding rod 15 or the outer sliding rod 17 to move downward. During this process, the return spring 21 is compressed. When the inner cam 13 and the outer cam 11 move to the notched sections in the inner cam track 14 and the outer cam track 12 respectively, the return spring 21 provides a return force to drive the corresponding internal pressure bottle head 8 and the external pressure bottle head 6 to reset.
