Description

Technical Field

[0001] This utility model belongs to the field of packaging machinery technology, specifically relating to an adjustable twin-screw bottle separating mechanism and labeling equipment. Background Technology

[0002] Bottle-separating mechanisms with bottle-separating screws are known. For example, Chinese utility model patent CN215556960U discloses a bottle-separating device, comprising: a frame; a drive motor; two screws, each rotatably supported on the frame, arranged with parallel axes forming a bottle-separating channel for containers to pass through; wherein the two screws have identical construction and each has an input shaft, on which a first gear with identical construction is fixedly mounted; and a second gear is provided on the output shaft of the drive motor, the second gear being coupled to the first gear via a transmission mechanism designed as a double-sided toothed synchronous belt, the two first gears being respectively disposed on the inner and outer sides of the double-sided toothed synchronous belt, so that the drive motor can simultaneously drive the two screws to rotate in opposite directions at the same speed.

[0003] However, since the screw is designed for containers of a specific size, it can only be used to separate similar containers with little difference in size, and is less adaptable to containers with large size differences.

[0004] Therefore, there is an urgent need to improve the existing bottle-separating mechanism and corresponding labeling equipment so that they can be more widely applied to containers of different sizes. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable twin-screw bottle-separating mechanism and labeling device. This twin-screw bottle-separating mechanism allows for horizontal length adjustment, enabling it to be adapted to different container sizes and expanding its application range. Simultaneously, it avoids the need to prepare various sizes or models of screws for different container dimensions, thus reducing production costs.

[0006] The aforementioned technical problem is solved by an adjustable twin-screw bottle-separating mechanism. This mechanism includes two screw units, a drive motor, a first transmission mechanism for the first screw unit, and a second transmission mechanism for the second screw unit. A drive gear is mounted on the output shaft of the drive motor, meshing with a first intermediate gear. The first and second intermediate gears are fixed to opposite ends of a first rotating shaft in a manner that prevents relative rotation. The first intermediate gear also meshes with a first input gear of the first transmission mechanism, and the second intermediate gear meshes with a second input gear of the second transmission mechanism. The first transmission mechanism and the first screw unit are fixed to a laterally adjustable adjustment mechanism, and the thickness of the first intermediate gear is greater than the thickness of the first input gear. Similarly, the second transmission mechanism and the second screw unit are fixed to the laterally adjustable adjustment mechanism, and the thickness of the second intermediate gear is greater than the thickness of the second input gear. Adjustability is achieved by fixing the screw units and their corresponding transmission mechanisms to the adjustment mechanism. In addition, the thickness of the intermediate gear (the longitudinal dimension of the first rotating shaft) is designed to be greater than the thickness of the corresponding input gear, so that the input gear can still maintain the meshing state even after the transmission mechanism shifts laterally, ensuring that the function is intact.

[0007] Preferably, each of the two screw units includes a screw, a support mechanism, and a base plate, and the screw unit is fixed to the adjustment mechanism via the base plate. The screw unit as a whole is fixed to the adjustment mechanism via the base plate. However, it is also possible to fix it to the adjustment mechanism via a side wall or other parts.

[0008] Advantageously, the adjusting mechanism includes a turbine and a worm gear, the turbine being fixedly connected to the base plate of a corresponding screw unit. The base plate of the screw unit is connected to a movable part of the adjusting mechanism, thereby enabling adjustment of the screw unit. The adjusting mechanism may also include other mechanisms that convert rotation into translation, such as rack and pinion mechanisms.

[0009] Preferably, a rotating handle is provided at the exposed end of the worm gear, allowing for manual adjustment by the user.

[0010] Furthermore, the first and second transmission mechanisms are identically constructed and each includes an input gear, a first bevel gear, a second bevel gear, and a first sprocket. The first bevel gear and the input gear are fixed at both ends of the second rotating shaft, while the second bevel gear and the first sprocket are arranged at both ends of the third rotating shaft. The first bevel gear meshes with the second bevel gear, and the first sprocket is connected to the input end of the screw unit via a transmission chain or toothed belt. This achieves a compact transmission mechanism.

[0011] Preferably, the first transmission mechanism is arranged below the base plate of the first screw unit and the second transmission mechanism is arranged below the base plate of the second screw unit. This makes full use of the available structural space.

[0012] In a preferred embodiment, the difference between the thickness of the first intermediate gear and the thickness of the first input gear is greater than or equal to the lateral adjustment distance of the adjusting mechanism. Therefore, the input gear remains engaged throughout the entire lateral movement of the transmission mechanism, ensuring proper transmission function.

[0013] Another advantage is that the two screw units are arranged in parallel on both sides of the conveyor chain, and the screw pitch is designed to increase from the input end to the output end. This ensures smooth container transport.

[0014] Preferably, the screw diameter is designed to increase from the input end to the output end. This makes the inlet of the bottle-separating mechanism conical, facilitating container entry.

[0015] This utility model also proposes a labeling device, which includes a conveying mechanism, a labeling mechanism, and a main heat shrink oven, wherein the aforementioned adjustable twin-screw bottle separating mechanism is provided upstream of the labeling mechanism.

[0016] In the bottle-separating mechanism and labeling device according to this application, lateral adjustability is achieved by arranging the screw unit and its transmission mechanism on the adjusting mechanism, thereby enabling wider application to containers of different sizes. Furthermore, it saves on the various expenses associated with manufacturing and storing screws of different sizes and replacing screws, thus reducing production costs. Attached Figure Description

[0017] Figure 1 This is a schematic diagram of the adjustable twin-screw bottle-separating mechanism of this utility model, viewed from an oblique top.

[0018] Figure 2 yes Figure 1 A top view of the bottle-splitting mechanism. Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] In existing labeling equipment, the screw of the bottle-separating mechanism is usually fixed, thus only usable for containers of specific sizes. For containers of different sizes, it is typically necessary to change to a different screw. This results in the need to prepare multiple models of screws during production, and the replacement of screws is quite time-consuming. The solution disclosed in this utility model avoids the above problems with a simple structure and low cost.

[0021] Figure 1 A perspective view of an adjustable twin-screw bottle-separating mechanism according to a preferred embodiment of the present invention is shown. The twin-screw bottle-separating mechanism 100 includes two screw units 1. Each screw unit 1 includes a screw 2, a support mechanism 3, and a base plate 4. The support mechanism 3 includes, for example, two opposing support plates with support holes designed on them, each with a bearing for receiving a mandrel of the screw. Here, the screws 2 of the two screw units are arranged parallel to each other on both sides of a conveyor chain 5. During the operation of the bottle-separating mechanism, the two screws rotate at the same speed in opposite directions. Figure 1 In the illustrated scheme, two screw units 1 are respectively fixed to the adjusting mechanism 6 via the base plate 4. However, it is also possible to consider only one screw unit fixed to the adjusting mechanism, or the adjusting unit fixed to the adjusting mechanism 6 via a side wall or other part. The adjusting mechanism 6 includes components for converting rotation into translation, such as a worm gear assembly, a rack and pinion, etc. Additionally, a rotating handle can be provided at the exposed end of the worm. Here, the base plate of the screw unit is fixedly connected to the movable part of the adjusting mechanism, such as the worm or rack. Therefore, the position of the screw unit can be adjusted laterally by rotating the handle.

[0022] The two screw units 1 are designed with identical structures. The pitch and diameter of the screws in both screw units 1 increase from the input end to the output end. Here, the increase can be a gradual increase in stages from the input end to the output end, a continuous increase, or an increase from the input end to a certain length and then remaining constant until the output end. Thus, the input end of the screw in the bottle-separating mechanism is tapered, which facilitates the entry of containers.

[0023] The screw unit 1 is driven by a drive motor 15. A drive gear 7 is mounted on the output shaft of the drive motor 15. This drive gear 7 meshes with a first intermediate gear 8. The first intermediate gear 8 and the second intermediate gear 9 are fixed at opposite ends of a first rotating shaft in a manner that prevents relative rotation. The first rotating shaft extends transversely to the longitudinal direction of the transmission chain. Furthermore, a first transmission mechanism is provided for the first screw unit of the two screw units 1, and a second transmission mechanism is provided for the second screw unit of the two screw units 1. The first intermediate gear 8 also meshes with a first input gear 10 of the first transmission mechanism, and the second intermediate gear 9 meshes with a second input gear 11 of the second transmission mechanism. Figure 1In the illustrated scheme, the first transmission mechanism and the first screw unit are fixed to an adjustment mechanism that can be adjusted laterally, and the thickness of the first intermediate gear 8 is greater than the thickness of the first input gear 10; and / or the second transmission mechanism and the second screw unit are fixed to an adjustment mechanism 6 that can be adjusted laterally, and the thickness of the second intermediate gear 9 is greater than the thickness of the second input gear 11. Therefore, even if the lateral position of the first or second input gear changes, the meshing state with the first or second intermediate gear can still be ensured. Here, thickness refers to the dimension along the longitudinal direction of the first rotation axis.

[0024] The first and second transmission mechanisms are constructed identically and each includes input gears in the form of first and second input gears 10 and 11, respectively, a first bevel gear 12, a second bevel gear 13, and a first sprocket 14. The first bevel gear 14 and the input gears are fixed at both ends of the second rotating shaft, and the second bevel gear 13 and the first sprocket 14 are respectively arranged at both ends of the third rotating shaft. The first bevel gear 12 meshes with the second bevel gear 13, and the first sprocket 14 is connected to the input end of the screw unit via a transmission chain or toothed belt. The third rotating shaft is orthogonal to the first or second rotating shaft. That is, the third rotating shaft is parallel to the longitudinal extension of the screw. Here, the input end of the screw unit 1 includes a gear transmission mechanism. That is, the power input to the input end is further transmitted to the screw spindle through the gear transmission mechanism, for example, for further deceleration.

[0025] Depend on Figure 1 It can be seen that the first transmission mechanism is arranged below the base plate 4 of the first screw unit, and the second transmission mechanism is arranged below the base plate 4 of the second screw unit. This fully utilizes the available structural space, achieving a rational spatial arrangement.

[0026] Figure 2 It shows Figure 1 A top view of the bottle-separating mechanism 100. Figure 2 It is clear that the screw 2 of the bottle-separating mechanism 100 has a smaller diameter at the input end, thus facilitating container introduction. Additionally, the screw pitch at the input end is also smaller. Both screws 2 are designed to be tapered at the input end, meaning their diameter gradually increases from the input end towards the output end. Similarly, the screw pitch increases from the input end towards the output end. Of course, the screws can be designed differently. For example, the diameter can gradually increase from the input end towards the output end in stages, continuously, or increase from the input end to a certain length and then remain constant. The two screws are arranged parallel to each other on both sides of the conveyor chain, which passes through the bottle-separating mechanism at the middle position of the screws. Here, both screws 2 are driven by the same drive motor 15, so that the two screws 2 rotate at the same speed but in opposite directions during the operation of the bottle-separating mechanism.

[0027] This utility model also discloses a labeling device. The labeling device includes a conveying mechanism, a labeling mechanism, and a main heat shrink oven, wherein the aforementioned adjustable twin-screw bottle-separating mechanism is provided upstream of the labeling mechanism. Here, the conveying mechanism is, for example, a conveyor chain or a conveyor belt.

[0028] In this labeling device, adjustability is achieved by integrating the screw unit and corresponding transmission mechanism together on the adjustment mechanism, allowing for more flexible setting of the lateral spacing between the two screws. This ensures that the same bottle-separating mechanism can be used with containers of a wider size range, and that only the distance between the two screws needs to be adjusted when container size changes, eliminating the need for laborious screw replacements and improving efficiency. Furthermore, due to the wider applicability of the bottle-separating mechanism, there is no need to prepare more screw specifications during production, nor to frequently replace screws when the size of the container to be labeled changes. Therefore, production costs are reduced.
