AI Technical Summary
During the labeling process on the entire bottle, the label paper on the outside of the bottle neck is suspended, resulting in poor adhesion between the front and back edges of the label paper and affecting the forming effect.
The bottle fixing device uses an inner pressure bottle head to press against the bottle mouth and an outer pressure bottle head to press against the top of the bottle body, ensuring the support of the label on the outside of the bottle neck. The periodic movement of the outer and inner drive parts causes the outer and inner pressure bottle heads to move up and down periodically, thus completing the firm adhesion of the label.
This ensures the label is firmly attached to the outside of the bottle neck, improving the overall label forming effect.

Abstract
Description
Technical Field
[0001] This invention relates to the field of labeling machine technology, and in particular to a bottle fixing device. Background Technology
[0002] Currently, some clients require full-body labeling on the entire bottle. The height of the label used for full-body labeling is the distance from the bottle neck to the bottom. During labeling, hot melt adhesive is first sprayed onto the bottle body. After spraying, the bottle continues to rotate while moving forward to the labeling station. The sprayed adhesive on the bottle body first contacts and adheres to the front edge of the label paper in the labeling station. Then, as the bottle rotates, the label paper is wrapped around the bottle. During the wrapping process, the labeling station simultaneously applies adhesive to the back edge of the label paper, ensuring that the front edge of the wrapped label adheres firmly to the bottle body while the back edge overlaps and adheres to the front edge. The final label form is tightly adhered to the bottle body, with the outer part of the bottle neck forming a paper tube shape. After the label is applied, the bottle continues to rotate and rolls forward over a brush. The brush deforms the label paper on the outer part of the bottle neck, causing it to adhere to the bottle neck. The overall effect is as follows: Figure 8 As shown, the labeling process is now complete. However, during the actual labeling process, it was found that due to the narrowness of the bottle neck, the label paper on the outside of the bottle neck was suspended in the air, resulting in poor adhesion between the front and back sides of the label paper. This caused the label paper to come unglued when it was shaped with a brush, affecting the final product. Summary of the Invention
[0003] To address the aforementioned problems, embodiments of the present invention provide a bottle fixing device.
[0004] This invention provides a bottle-fixing device, including a bottle-pressing turntable with bottle-pressing mechanisms spaced apart on it. Each bottle-pressing mechanism includes an outer bottle-pressing unit and an inner bottle-pressing unit. The outer bottle-pressing unit includes an outer drive unit and an outer bottle-pressing head, while the inner bottle-pressing unit includes an inner drive unit and an inner bottle-pressing head. The inner bottle-pressing head is adapted to the bottle opening of the packaging bottle, and the outer bottle-pressing head is cylindrical with a diameter adapted to the bottle body. The inner bottle-pressing head is placed inside the outer bottle-pressing head with a clearance fit. During the synchronous rotation of the packaging bottle and the bottle-pressing turntable, the inner drive unit drives the inner bottle-pressing head downwards to press against the bottle opening, and the outer drive unit drives the outer bottle-pressing head downwards to press against the top of the bottle body. Thus, during the labeling process, the outer bottle-pressing head supports the label paper on the outer side of the bottle neck to ensure firm adhesion.
[0005] During the rotation of the bottle pressing turntable, the outer drive unit drives the outer pressing bottle head to move up and down periodically, and the inner drive unit drives the inner pressing bottle head to move up and down periodically, thereby completing the following: after the packaging bottle enters the bottle pressing turntable from the bottle inlet position, the inner pressing bottle head moves downward to press against the bottle mouth; before the packaging bottle moves to the labeling station position, the outer pressing bottle head moves downward to coaxially fit around the bottle neck with the bottom contacting the top of the bottle body; after the full label is pasted, the outer pressing bottle head moves upward to reset; and finally, before the packaging bottle is sent out from the bottle outlet position, the inner pressing bottle head moves upward to reset.
[0006] Compared with the prior art, the beneficial effects of the present invention are as follows: by using an external pressure bottle head, the label on the outer part of the bottle neck is supported during the labeling process, so that the overlap is firmly bonded and the subsequent shaping effect is guaranteed.
[0007] Optionally, a cam disk is provided above the bottle pressing turntable. The bottle pressing turntable and the cam disk are coaxially arranged and can rotate relative to the cam disk. The external drive unit includes an outer cam and an outer cam track provided on the lower surface of the cam disk. The outer cam track is concentric with the cam disk. The outer cam contacts the outer cam track and is connected to the outer bottle pressing head for transmission. During the rotation of the bottle pressing turntable relative to the cam disk, the outer cam drives the outer bottle pressing head to move up and down periodically under the action of the outer cam track.
[0008] Optionally, the internal drive unit includes an inner cam and an inner cam track disposed on the lower surface of the cam disk. The inner cam track is concentric with the cam disk. The inner cam contacts the inner cam track and is connected to the inner pressure bottle head via transmission. During the rotation of the pressure bottle turntable relative to the cam disk, the inner cam drives the inner pressure bottle head to move up and down periodically under the action of the inner cam track.
[0009] Optionally, the internal drive unit also includes an internal sliding rod that slides vertically through the bottle pressing turntable. The internal bottle pressing head is rotatably mounted at the bottom end of the internal sliding rod. An internal transmission module is provided on one side of the internal sliding rod on the bottle pressing turntable. An internal cam is mounted on the internal transmission module. As the internal cam rolls along the internal cam track, it provides downward pressure and upward restoring force to the internal sliding rod through the internal transmission module.
[0010] Optionally, the external drive unit also includes a connecting sleeve that is coaxially and slidably sleeved on the inner sliding rod. The outer pressure head is coaxially and rotatably sleeved on the outer periphery of the connecting sleeve. An outer sliding rod is vertically arranged on the connecting sleeve and slides upward through the pressure plate. An outer transmission module is arranged on the pressure plate on one side of the outer sliding rod. An outer cam is arranged on the outer transmission module. During the rolling process of the outer cam along the outer cam track, the outer cam provides downward pressure and upward reset force to the outer sliding rod through the outer transmission module.
[0011] Optionally, the internal transmission module has the same structure as the external transmission module, including a fixed column that is vertically fixed on the bottle pressing turntable, a sliding seat that is slidably arranged on the fixed column, and a return spring that is arranged between the sliding seat and the fixed column to provide a return force.
[0012] Optionally, the sliding seat is U-shaped, with its two sides slidingly mounted to the fixed post. A locking bolt is fixed on the fixed post between the two sides of the sliding seat, and a return spring is connected between the locking bolt and the sliding seat. Attached Figure Description

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this invention are used to explain the invention, but are not intended to limit the invention.
[0024] See Figures 1-7 The present invention provides a bottle fixing device, including a bottle pressing turntable 1, on which bottle pressing mechanisms 2 are spaced apart. The bottle pressing mechanism 2 includes an outer bottle pressing unit 3 and an inner bottle pressing unit 4. The outer bottle pressing unit 3 includes an outer driving part 5 and an outer bottle pressing head 6. The inner bottle pressing unit 4 includes an inner driving part 7 and an inner bottle pressing head 8. The inner bottle pressing head 8 is adapted to the bottle mouth of the packaging bottle 9. The outer bottle pressing head 6 is cylindrical and its diameter is adapted to the bottle body of the packaging bottle 9. The inner bottle pressing head 8 is placed inside the outer bottle pressing head 6 and the two are fitted with a gap. During the synchronous rotation of the packaging bottle 9 and the bottle pressing turntable 1, the inner driving part 7 drives the inner bottle pressing head 8 downward to press against the bottle mouth of the packaging bottle 9, and the outer driving part 5 drives the outer bottle pressing head 6 downward to press against the top of the bottle body of the packaging bottle 9. Thus, during the labeling process, the outer bottle pressing head 6 supports the label paper on the outside of the neck of the packaging bottle 9 to ensure that it is firmly pasted.
[0025] During the rotation of the bottle pressing turntable 1, the outer drive unit 5 drives the outer pressing bottle head 6 to move up and down periodically, and the inner drive unit 7 drives the inner pressing bottle head 8 to move up and down periodically, thereby completing the following: after the packaging bottle 9 enters below the bottle pressing turntable 1 from the bottle inlet position, the inner pressing bottle head 8 moves downward to press against the bottle mouth of the packaging bottle 9; before the packaging bottle 9 moves to the labeling station position, the outer pressing bottle head 6 moves downward to coaxially fit around the neck of the bottle in a way that the bottom contacts the top of the bottle body; after the label is pasted on the whole body, the outer pressing bottle head 6 moves upward to reset; and finally, before the packaging bottle 9 is sent out from the bottle outlet position, the inner pressing bottle head 8 moves upward to reset.
[0026] In practice, 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 central guide plate. Each bottle pressing mechanism 2 is equipped with a bottle holding mechanism below it. The bottle holding mechanism will rotate synchronously with the bottle pressing turntable 1. Each packaged bottle 9 will be fed into a bottle holding mechanism by the bottle feeding star wheel. The central guide plate, bottle feeding star wheel, bottle discharging star wheel and bottle holding mechanism are all existing equipment, and the specific structure will not be described in detail.
[0027] In practice, a cam disk 10 is provided above the bottle pressing turntable 1. The bottle pressing turntable 1 and the cam disk 10 are coaxially arranged and can rotate relative to the cam disk 10. The external drive unit 5 includes an outer cam 11 and an outer cam track 12 provided on the lower surface of the cam disk 10. The outer cam track 12 is concentric with the cam disk 10. The outer cam 11 contacts the outer cam track 12 and is connected to the outer bottle pressing head 6 for transmission. During the rotation of the bottle pressing turntable 1 relative to the cam disk 10, the outer cam 11 drives the outer bottle pressing head 6 to move up and down periodically under the action of the outer cam track 12.
[0028] In practice, the inner drive unit 7 includes an inner cam 13 and an inner cam track 14 provided on the lower surface of the cam disk 10. The inner cam track 14 is concentric with the cam disk 10. The inner cam 13 contacts the inner cam track 14 and is connected to the inner pressure bottle head 8 for transmission. During the rotation of the pressure bottle turntable 1 relative to the cam disk 10, the inner cam 13 drives the inner pressure bottle head 8 to move up and down periodically under the action of the inner cam track 14.
[0029] Both the outer cam track 11 and the inner cam track 14 include an upward-facing notch segment. The difference is that the notch segment of the inner cam track 14 is shorter than that of the outer cam track 11, and along the rotation direction of the pressure vessel turntable 1, the starting point of the notch segment of the inner cam track 14 is at the rear and the ending point is at the front. For specific implementation details, please refer to... Figure 4 In the inner cam track 14, the upward notch between A and B is opposite to the central guide plate. During the labeling process, the packaging bottle 9 is fed into the bottle pressing turntable 1 by the bottle inlet star wheel and rotates with the bottle pressing turntable 1 relative to the cam plate 10. During the rotation, the inner cam 13 first reaches point A. After that, the inner cam track 14 begins to press down on the inner cam 13. The inner cam 13 drives the inner bottle pressing head 8 to press against the bottle mouth of the packaging bottle 9. The packaging bottle 9 continues to rotate with the bottle pressing turntable 1. When the outer cam 11 moves to point C of the outer cam track 12, the outer cam track 12 begins to press down on the outer cam 11. The outer cam 11 drives the outer bottle pressing head 6 downward to press against the bottle body. After the top is pressed tightly and both the inner and outer pressure bottle heads are pressed tightly, the packaging bottle 9 begins to enter the labeling station area for labeling. During the labeling process, due to the support of the outer pressure bottle head 6, the back side of the label is firmly adhered to the overlap of the front side. After the labeling is completed, when the outer cam 11 moves to point D of the outer cam track 12, the outer cam 11 begins to move upward and simultaneously drives the outer pressure bottle head 6 to return to its original position. Then, when the inner cam 13 moves to point B of the inner cam track 14, the inner cam 13 begins to move upward and simultaneously drives the inner pressure bottle head 8 to return to its original position. Finally, the labeled packaging bottle 9 is sent out through the bottle ejection star wheel in the central guide plate.
[0030] In practice, the inner drive unit 7 also includes an inner sliding rod 15 that slides vertically through the bottle pressing turntable 1. The inner bottle pressing head 8 is rotatably disposed at the bottom end of the inner sliding rod 15. An inner transmission module is disposed on one side of the inner sliding rod 15 on the bottle pressing turntable 1. An inner cam 13 is disposed on the inner transmission module. During the rolling process of the inner cam 13 along the inner cam track 14, the inner cam 13 provides downward pressure and upward reset force to the inner sliding rod 15 through the inner transmission module.
[0031] The external drive unit 5 also includes a connecting sleeve 16 that is coaxially and slidably sleeved on the inner sliding rod 15. The outer pressure head 6 is coaxially and rotatably sleeved on the outer periphery of the connecting sleeve 16. An outer sliding rod 17 is vertically arranged on the connecting sleeve 16. Specifically, the outer sliding rod 17 can be fixed by a connecting arm 18 that is horizontally arranged on the connecting sleeve 16. The outer sliding rod 17 slides upward through the pressure turntable 1. An external transmission module is arranged on the pressure turntable 1 on one side of the outer sliding rod 17. An outer cam 11 is arranged on the external transmission module. During the rolling process of the outer cam 11 along the outer cam track 12, the outer cam 11 provides downward pressure and upward restoring force to the outer sliding rod 17 through the external transmission module.
[0032] The internal transmission module has the same structure as the external transmission module, including a fixed column 19 that is vertically fixed on the bottle pressing turntable 1, a sliding seat 20 that is slidably arranged on the fixed column 19, and a return spring 21 that is arranged between the sliding seat 20 and the fixed column 19. The return spring 21 is used to provide a return force.
[0033] The sliding seat 20 is U-shaped, and its two sides are slidably disposed with the fixed post 19. A locking bolt 22 is fixed on the fixed post 19 and located between the two sides of the sliding seat 20. A return spring 21 is connected between the locking bolt 22 and the sliding seat 20.
[0034] In practice, the inner cam 13 and the outer cam 11 are fixed on the side of the corresponding sliding seat 20, and the inner sliding rod 15 and the outer sliding rod 17 are fixed to the corresponding sliding seat 20. The two ends of the return spring 21 are connected to the locking bolt 22 and the upper side of the sliding seat 20, respectively. Under the action of the inner cam 13 or the outer cam 11, the sliding seat 20 moves downward, which drives 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 notch section in the inner cam track 14 and the outer cam track 12, respectively, the return spring 21 provides a reset force to drive the corresponding inner pressure bottle head 8 and the outer pressure bottle head 6 to reset.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention are included within the scope of protection of the present invention.
