Description

Technical Field

[0001] This utility model relates to the field of bottle washing and filling bottle protection technology, and more specifically to the field of a scratch-resistant structure for star wheel bottles in a liquor packaging line. Background Technology

[0002] In automated production of baijiu packaging, filling machines and bottle washing machines are core equipment. The star wheel, as a key component enabling precise bottle flow positioning, indexing, and motion conversion, has a decisive impact on the efficiency, stability, and final product quality of the production line. It is particularly noteworthy that baijiu bottles have extremely high requirements for appearance integrity (scratches). Due to the characteristics of baijiu glass bottles, the baked-on patterns on the bottle body are easily scratched, affecting the appearance quality.

[0003] As a component that comes into direct, high-frequency, and forced contact with the bottle body, the star wheel's structural design, material selection, surface condition, and installation and adjustment precision are the main factors affecting bottle scratches. Conventional star wheel structures do not consider the impact of the star wheel structure on scratches. Therefore, developing a structure that can effectively prevent or significantly reduce scratches caused by the star wheel during operation is of great practical value and urgency for ensuring the appearance quality of liquor, reducing production losses, and meeting the quality requirements for ensuring the appearance quality of packaging bottles under high-speed operation. Utility Model Content

[0004] The purpose of this invention is to solve the problem of scratching when the star wheel of a bottle washing machine, drainer, or filling machine comes into contact with the bottle during bottle passage in existing packaging production lines. This invention provides a scratch-resistant structure for the star wheel of a liquor packaging line. Utilizing the principle of contactless or reduced contact area, and through dynamic adjustment of the contact point between the star wheel and the bottle, this method achieves adjustability of the star wheel's contact surface during bottle passage, avoiding the risk of bottle scratches caused by large-area contact.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: This utility model provides a scratch-resistant structure for a liquor bottle using a star wheel design in a liquor packaging line. It includes an upper star wheel and a lower star wheel positioned below it. Both the upper and lower star wheels have corresponding arc-shaped protective plates on their outer sides. Several star wheel grooves are evenly distributed around the edges of both the upper and lower star wheels. The groove shape matches the outer contour of the liquor bottle. Each star wheel groove and the contact point between the arc-shaped protective plate and the outer contour of the bottle is equipped with a scratch-resistant structure to prevent scratching of the bottle's outer contour.

[0006] In one embodiment, the scratch-resistant structure is a plurality of embedded flexible guide strips.

[0007] In one embodiment, the upper and lower surfaces of the upper and lower star wheel disks are provided with star wheel grooves that cooperate with the corresponding star wheel grooves. Each star wheel groove is an arc-shaped groove with the same direction as the corresponding star wheel groove. An embedded flexible guide strip is embedded in the star wheel groove, and the embedded flexible guide strip part is located in the corresponding star wheel groove.

[0008] In one embodiment, the thickness of the embedded flexible guide strip on the upper or lower star wheel gradually decreases at both ends as the upper or lower star wheel rotates.

[0009] Specifically, the two ends of the embedded flexible guide bar, which rotate along the star wheel, are ground into a form with gradually decreasing convex height after installation, as required.

[0010] In one embodiment, grooves are provided on both the top and bottom surfaces of the arc-shaped protective plate. Each groove is an arc-shaped groove that runs in the same direction as the corresponding arc-shaped protective plate. An embedded flexible guide strip is installed in the groove, and the thickness of the embedded flexible guide strip gradually decreases at both ends.

[0011] In one embodiment, a groove stop is provided at one end of the guard plate groove to limit the displacement of the corresponding embedded flexible guide strip.

[0012] In one embodiment, each star wheel groove is provided with a wine bottle contact surface, which is an embedded vertical groove surface that contacts the bottle body.

[0013] In one embodiment, the embedded flexible guide strip includes a vertical arc plate and a horizontal arc plate disposed on the back side of the upper and lower edges of the vertical arc plate. An arc-shaped retaining strip matching the thickness of the guard plate groove or star wheel groove is disposed below the edge of the horizontal arc plate located at the upper edge. The vertical arc-shaped plate is attached to the arc-shaped surface of the corresponding star wheel groove or circular ring guard plate.

[0014] In one embodiment, the front of the vertical arc-shaped plate is provided with multiple parallel arc-shaped column protrusions in the horizontal direction. The multiple arc-shaped column protrusions have the same height, and the outer side of the multiple arc-shaped column protrusions contacts the body of the wine bottle.

[0015] Specifically, the position of the curved column protrusions on the vertical curved plate can be customized according to the contact position requirements. After the embedded flexible guide strip is embedded, the curved column protrusions at different positions can effectively prevent the bottle body's baked-on pattern from being bumped or effectively reduce the contact area, ensuring the protection of the bottle body's baked-on pattern.

[0016] In one embodiment, each arc-shaped column protrusion is provided with a protrusion mounting groove at its mounting location; The material of the arc-shaped retaining strip is polytetrafluoroethylene, and the thickness of the arc-shaped retaining strip is less than or equal to the depth of the guard plate groove or star wheel groove.

[0017] Specifically, the material of the curved clip can be polytetrafluoroethylene. The curved clip is embedded in the groove (protective plate groove or star wheel groove). To ensure that there is no hard impact when the bottle passes through, the thickness of the curved clip should be less than or equal to the depth of the protective plate groove or star wheel groove. After assembly, the width of the vertical curved plate should be greater than the depth of the groove.

[0018] The beneficial effects of this utility model are as follows: 1. In this utility model, by matching the embedded flexible guide strip with the protrusions at different positions to avoid or reduce the contact position of the bottle body's baked-on surface, this physical isolation principle effectively avoids contact between easily scratched areas of the bottle, and plays a good protective role for the baked-on surface of the bottle.

[0019] 2. The assembly structure of this utility model, featuring an integrally embedded flexible guide strip, combines the structural embedding strength of the arc-shaped clip assembly with the flexibility of dynamic adjustment, greatly improving the compatibility of different star wheel structures and maximizing compatibility with different bottle types. Ultimately, it can significantly reduce the scratch rate of the bottle body and baking decoration during the rotating star wheel process in liquor packaging, improving product appearance quality and pass rate, avoiding downtime due to quality issues, and thus improving the operating efficiency of the packaging line.

[0020] 3. To ensure no rigid impact when the bottle contacts or detaches from the guide strip, the two ends of the embedded flexible guide strip, rotating along the star wheel, are ground into a gradually decreasing height convex shape after installation, forming a transition surface. This ensures that the height of the two ends smoothly transitions to be flush with the working surface of the bottle in contact with the star wheel. Similarly, the embedded flexible guide strip is embedded into the groove of the arc-shaped guard plate, with the end assembly extending until the groove stops. During operation, observe whether the selected arc-shaped column convex strip scratches the baked-on surface. Different convex strip mounting slots can be flexibly selected to replace the arc-shaped column convex strip to ensure scratch resistance. Finally, overall batch adjustments are made.

[0027] Example 1 like Figures 1 to 2As shown in the figure, this embodiment provides a scratch-resistant structure for a star wheel bottle in a liquor packaging line, including an upper star wheel 1 and a lower star wheel 2 located below the upper star wheel 1. Corresponding arc-shaped protective plates 3 are provided on the outer sides of both the upper and lower star wheel 1 and lower star wheel 2. Several star wheel grooves 5 are evenly distributed around the edges of the upper and lower star wheel 1 and lower star wheel 2. The groove shape of the star wheel grooves 5 matches the outer contour of the liquor bottle. Scratch-resistant structures are provided at each star wheel groove 5 and at the contact points between the arc-shaped protective plates 3 and the outer contour of the liquor bottle to prevent scratching of the outer contour of the liquor bottle.

[0028] Example 2 like Figures 1 to 2 As shown in the figure, this embodiment provides a scratch-resistant structure for a star wheel bottle in a liquor packaging line, including an upper star wheel 1 and a lower star wheel 2 located below the upper star wheel 1. Corresponding arc-shaped protective plates 3 are provided on the outer sides of both the upper and lower star wheel 1 and lower star wheel 2. Several star wheel grooves 5 are evenly distributed around the edges of the upper and lower star wheel 1 and lower star wheel 2. The groove shape of the star wheel grooves 5 matches the outer contour of the liquor bottle. Scratch-resistant structures are provided at each star wheel groove 5 and at the contact points between the arc-shaped protective plates 3 and the outer contour of the liquor bottle to prevent scratching of the outer contour of the liquor bottle.

[0029] The scratch-resistant structure consists of several embedded flexible guide strips 6.

[0030] In this embodiment, by matching the embedded flexible guide strip 6 with the protrusions at different positions to avoid or reduce the contact positions of the bottle body's baked-on surface, this physical isolation principle effectively avoids contact between easily scratched areas of the bottle, providing excellent protection for the bottle's baked-on surface.

[0031] Example 3 This embodiment is a further optimization based on embodiment 2, specifically: The upper and lower surfaces of the upper star wheel disk 1 and the lower star wheel disk 2 are provided with star wheel grooves 4 that cooperate with the corresponding star wheel grooves 5. Each star wheel groove 4 is an arc-shaped groove with the same direction as the corresponding star wheel groove 5. The embedded flexible guide strip 6 is embedded in the star wheel groove 4, and part of the embedded flexible guide strip 6 is located in the corresponding star wheel groove 4.

[0032] The thickness of the embedded flexible guide strip 6 on the upper star wheel 1 or the lower star wheel 2 gradually decreases at both ends as the upper star wheel 1 or the lower star wheel 2 rotates.

[0033] Specifically, the two ends of the embedded flexible guide bar 6, which rotate along the star wheel, are ground into a form with gradually decreasing convex height after installation, as required.

[0034] Example 4 This embodiment is a further optimization based on embodiment 2, specifically: The top and bottom surfaces of the arc-shaped protective plate 3 are provided with protective plate grooves 11. Each protective plate groove 11 is an arc-shaped groove that is consistent with the direction of the corresponding arc-shaped protective plate 3. The embedded flexible guide strip 6 is embedded in the protective plate groove 11, and the thickness of the two ends of the embedded flexible guide strip 6 gradually decreases.

[0035] A groove stop 10 is provided at one end of the guard plate groove 11 to limit the displacement of the corresponding embedded flexible guide strip 6.

[0036] Each star wheel groove 5 is provided with a wine bottle contact surface 7, which is an embedded vertical groove surface 8 that contacts the bottle body.

[0037] Example 5 This embodiment is a further optimization based on embodiment 4, specifically: The embedded flexible guide strip 6 includes a vertical arc plate and a horizontal arc plate set on the back side of the upper and lower edges of the vertical arc plate. An arc-shaped clip 13 matching the thickness of the guard plate groove 11 or the star wheel groove 4 is set below the edge of the horizontal arc plate located at the upper edge. The vertical arc-shaped plate is attached to the arc-shaped surface of the corresponding star wheel groove 5 or the circular ring guard plate 3.

[0038] The front of the vertical arc plate has multiple parallel arc-shaped column protrusions 12 arranged horizontally. The multiple arc-shaped column protrusions 12 have the same height, and the outer side of the multiple arc-shaped column protrusions 12 contacts the body of the wine bottle.

[0039] Specifically, the position of the arc-shaped column protrusion 12 on the vertical arc plate can be customized according to the contact position requirements. After the embedded flexible guide strip 6 is embedded, the arc-shaped column protrusion 12 at different positions can effectively prevent the bottle body baking pattern from being bumped or effectively reduce the contact area, ensuring the protection of the bottle body baking pattern.

[0040] Example 6 This embodiment is a further optimization based on embodiment 5, specifically: Each arc-shaped column protrusion 12 is provided with a protrusion mounting groove 9 at its mounting location; The material of the arc-shaped clip 13 is polytetrafluoroethylene, and the thickness of the arc-shaped clip 13 is less than or equal to the depth of the guard plate groove 11 or the star wheel groove 4.

[0041] Specifically, the material of the arc-shaped clip 13 can be polytetrafluoroethylene. The arc-shaped clip 13 is embedded in the groove (protective plate groove 11 or star wheel groove 4). To ensure that there is no hard impact when the bottle passes through, the thickness of the arc-shaped clip 13 is less than or equal to the depth of the protective plate groove 11 or star wheel groove 4. After assembly, the width of the vertical arc plate should be greater than the depth of the groove.

[0042] The overall embedded flexible guide strip 6 assembly structure of this design combines the structural embedding strength of the arc-shaped clip strip 13 assembly with the flexibility of dynamic adjustment, greatly improving the compatibility of different star wheel structures and maximizing compatibility with different bottle types. Ultimately, it can significantly reduce the scratch rate of the bottle body and baking decoration during the rotating star wheel process of liquor packaging, improve product appearance quality and pass rate, avoid downtime due to quality issues, and improve the operating efficiency of the packaging line.

[0043] To ensure no rigid impact when the bottle contacts or detaches from the guide strip, the two ends of the embedded flexible guide strip 6, rotating along the star wheel, are ground into a gradually decreasing height convex shape after installation, forming a transition surface. This allows the height of the two ends to smoothly transition to be flush with the working surface of the bottle in contact with the star wheel. Similarly, the embedded flexible guide strip 6 is embedded into the groove 11 of the arc-shaped guard plate, with the end assembled up to the groove stop 10. During operation, observe whether the selected arc-shaped column convex strip 12 scratches the baked-on surface. Different convex strip mounting slots 9 can be flexibly selected to replace the arc-shaped column convex strip 12 to ensure scratch resistance. Finally, overall batch adjustments are performed.
