Description

Technical Field

[0001] This utility model relates to the field of bottle detection technology, and in particular to a bottle rotating assembly. Background Technology

[0002] In the glass bottle manufacturing process, quality inspection is a crucial step in ensuring product qualification rates. Glass bottles need to undergo multiple inspection processes, including appearance defect inspection (such as cracks, bubbles, and scratches), dimensional accuracy inspection (such as bottle mouth diameter and bottle body roundness), label position inspection, and sealing tests. To achieve efficient and comprehensive inspection, the glass bottle usually needs to be fixed and driven to rotate around an axis so that inspection equipment (such as vision cameras and laser sensors) can acquire information about the bottle from multiple angles. Therefore, the clamping assembly used to hold and drive the rotation of the glass bottle becomes one of the core components of an automated inspection system.

[0003] Existing technology discloses a chuck assembly for a bottle-making machine, as detailed in utility model patent CN213446821U. This assembly includes a hollow shaft, with a clamping plate fixedly connected to its outer end. The clamping plate has several annularly distributed small shafts, the axes of which are parallel to the axis of the clamping plate. A gripper is movably sleeved on the outer end of each small shaft, and a torsion spring is provided between the gripper and the clamping plate to rotate the gripper outwards. A drive arm assembly is movably sleeved on the inner end of each small shaft, and the drive arm assembly is connected to the corresponding gripper. However, related technologies, including the aforementioned solution, still have many problems, such as: ① Insufficient clamping stability and safety: Glass bottles are smooth and fragile; if the clamping force of traditional clamps is too great, it may damage the bottle. Damage (such as indentation or cracking) and insufficient clamping force can easily lead to slippage or displacement during rotation, affecting detection accuracy. In addition, some fixtures lack adaptive adjustment functions, making it difficult to adapt to slight tolerance changes in the diameter of the bottle mouth or body; ② Complex rotary drive structure: Existing rotary mechanisms often use independent motor drive or transmission chain design, resulting in a large overall size of the fixture, making it difficult to integrate into a compact inspection station. The complex mechanical structure may introduce vibration or coaxiality deviation, further affecting the accuracy of the inspection results; Insufficient versatility: Most fixtures use fixed jaws or rigid structures, which are only suitable for glass bottles of specific sizes or shapes. When switching to different bottle types, it is necessary to frequently change the fixture or manually adjust the clamping parameters, resulting in reduced production efficiency and increased equipment costs. Utility Model Content

[0004] The purpose of this utility model is to provide a bottle-spinning assembly to solve the technical problems of poor clamping stability and safety, as well as the complexity and lack of versatility of the rotation drive structure that are common in existing bottle-spinning structures.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A bottle-spinning assembly, comprising:

[0007] Bottle support plate, used to support the bottle;

[0008] The clamping block is rotatably mounted relative to the bottle support plate to limit the position of the bottle on the bottle support plate;

[0009] A rotating component is fixedly installed relative to the bottle holder to drive the bottles on the bottle holder to rotate synchronously.

[0010] The clamping drive component is installed inside the rotating component and slides relative to it. It is linked with the clamping block to drive the clamping block to perform clamping or releasing actions.

[0011] Furthermore, the rotating assembly includes a spindle that is fixedly mounted relative to the bottle support plate, and the spindle is driven to rotate by an external power source.

[0012] Furthermore, the mandrel is rotatably mounted relative to the rotating bearing housing, which is fixedly mounted relative to the machine base. The top of the mandrel is fixedly mounted relative to the hollow shaft head, and the bottle support plate is fixedly mounted relative to the top of the hollow shaft head.

[0013] Furthermore, the clamping drive assembly includes a central shaft that passes through the inner cavity of the spindle and the hollow shaft head and is slidably mounted relative to both. The top of the central shaft is linked to the clamping block, and the clamping block is driven to clamp or release when the central shaft rises or falls.

[0014] Furthermore, an elastic element is installed between the central shaft and the mandrel, which is used to generate a preload force on the central shaft to cause it to move upward.

[0015] Furthermore, the top of the central shaft is fixedly installed relative to the connecting block, and both ends of the connecting block are rotatably installed with a connecting piece. The other end of the connecting piece is rotatably installed with a clamping block. The clamping block is rotatably installed with the hollow shaft head. When the central shaft rises or falls, the connecting block drives the connecting piece to rotate, which in turn drives the clamping block to rotate along the point where it is rotatably installed with the hollow shaft head, thereby achieving the clamping or loosening of the clamping block.

[0016] Furthermore, the clamping surface of the clamping block is set as an arc surface, and a connecting part is provided at the bottom of the arc surface. The connecting part is provided with a fixed rotating shaft hole and a rotating connecting hole. The fixed rotating shaft hole is used for rotatable connection with the hollow shaft head, and the rotating connecting hole is used for rotatable connection with the connecting piece.

[0017] Furthermore, the elastic element is a spring, which is fitted outside the central shaft and located below the shoulder of the central shaft, while also located above the annular platform inside the spindle cavity.

[0018] Furthermore, one end of the central shaft is rotatably mounted to the lifting bearing seat, which is in contact with an external power source and driven by the external power source to perform lifting movements. A pulley is fixedly mounted on the outside of the spindle, and the pulley is driven by the external power source to rotate synchronously to drive the spindle to rotate.

[0019] Furthermore, a linear bearing is installed between the inner cavity of the central shaft and the mandrel, with two linear bearings located at the top and bottom of the inner cavity of the mandrel, respectively.

[0020] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0021] (1). This utility model sets up a rotating component and a clamping drive component, which work together to realize the rotation of the bottle support plate to drive the bottle body to rotate. It also has the function of clamping or releasing the bottle body, which can realize multiple actions of loading and unloading the bottle body and rotating the bottle body during the clamping process. At the same time, by setting the shape of the clamping block, in conjunction with the clamping drive component, it is beneficial to ensure the stability and safety of the clamping block.

[0022] (2). By setting the position and connection relationship between the central shaft, the spindle, the hollow shaft head, the clamping block, and the bottle support plate, this utility model ingeniously realizes the coordinated action of rotation and gripping, avoiding the complex drive structure in the traditional structure, effectively ensuring the accuracy of the detection structure. At the same time, the design of the clamping block is suitable for bottles of various sizes, making it more widely applicable. Attached Figure Description

[0037] To address the limitations of existing technologies, this embodiment provides a technical solution. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0038] This utility model addresses the problems of insufficient clamping stability and safety, as well as complex or unversatile rotation drive mechanisms, that exist in existing automatic glass bottle inspection production lines when glass bottles need to be clamped and rotated. Therefore, this utility model discloses a bottle-rotating assembly that overcomes the problems of existing bottle clamping and rotating assemblies. The specific improvement is as follows:

[0039] See appendix Figure 1 and 2A bottle-spinning assembly includes: a bottle-supporting plate 200 for supporting a bottle; two clamping blocks 100, rotatably mounted relative to the bottle-supporting plate 200 to limit the bottle on the bottle-supporting plate 200, wherein the direction of relative rotation of the clamping blocks 100 relative to the bottle-supporting plate 200 is such that the two clamping blocks 100 rotate along the vertical axis, i.e., in the plane containing the axis of the bottle, i.e., the two clamping blocks 100 rotate synchronously to move closer or further apart, thereby clamping or releasing the bottle; a rotating assembly, fixedly mounted relative to the bottle-supporting plate 200 to drive the bottle on the bottle-supporting plate 200 to rotate synchronously; the rotating assembly includes a spindle 600, which is configured as a hollow sleeve structure, fixedly mounted relative to the bottle-supporting plate 200, and driven to rotate by an external power source. Specifically, a pulley 601 is fixedly mounted relative to the outside of the spindle 600, and the pulley 601 is driven to rotate synchronously by an external power source to drive the spindle 600 to rotate. The spindle 600 is rotatably mounted relative to the rotary bearing housing 500, which is fixedly mounted relative to the machine base. Specifically, the top of the spindle 600 is fixedly mounted to the hollow shaft head 400 by radially mounted screws, and the bottle support plate 200 is fixedly mounted relative to the top of the hollow shaft head 400 by vertically mounted screws. The spindle 600 and the inner cavity of the rotary bearing housing 500 are rotatably mounted through the upper bearing 502. The upper bearing 502 is an angular contact ball bearing, and there are two sets of upper bearings 502. A spacer 503 is also provided between the two sets of upper bearings 502. An end cover 501 is installed at the bottom of the rotary bearing housing 500. The end cover 501 is used to pre-tighten the outer ring of the upper bearing 502. In addition, a fixing nut 802 is installed on the spindle 600. The fixing nut 802 is used to position the inner ring of the upper bearing 502.

[0040] See appendix Figure 1-7A clamping drive assembly is slidably mounted within the rotating assembly and linked to the clamping block 100 to drive the clamping block 100 to perform clamping or releasing actions. Specifically, the clamping drive assembly includes a central shaft 800, which passes through the inner cavities of the spindle 600 and the hollow shaft head 400 and is slidably mounted relative to both. The top of the central shaft 800 is linked to the clamping block 100, driving the clamping block 100 to clamp or release when the central shaft 800 rises or falls. Specifically, two linear bearings 803 are installed between the central shaft 800 and the inner cavity of the spindle 600, located at the top and bottom of the inner cavity of the spindle 600 respectively. Additionally, the central shaft... The bottom end of 800 is rotatably mounted to the lifting bearing seat 700 via the lower bearing 701. The lifting bearing seat 700 is set to contact the external power and is driven by the external power to perform lifting and lowering movements. It can be understood that there are many ways to achieve this. For example, the external power is a cam that is rotated and mounted on the machine base. The cam contacts the external protrusion of the lifting bearing seat 700. A deep groove ball bearing can be installed on the external protrusion. The cam contacts the deep groove ball bearing. When the cam rotates, it drives the deep groove ball bearing to lift and lower, thereby driving the central shaft 800 to lift and lower. An elastic element 801 is installed between the central shaft 800 and the spindle 600. The elastic element 801 is used to generate a preload force on the central shaft 800, causing it to tend to move upward relative to the spindle 600. This preload force can be understood as the restoring force of the elastic element 801 on the central shaft 800. The elastic element 801 is a spring, which is sleeved on the outside of the central shaft 800 and located below the shoulder 804 of the central shaft 800, and above the annular platform 602 inside the spindle 600. When the spring is in the normal state, the central shaft 800 is at its highest point, and the clamping block 100 is clamped. When the central shaft 800 is lowered by an external force, the clamping block 100 opens, and the bottle is fed. Then, when the external force is removed, the central shaft 800 rises under the restoring action of the spring, and the clamping block 100 clamps. The top of the central shaft 800 is fixedly installed relative to the connecting block 900. Each end of the connecting block 900 is rotatably installed with a connecting piece 300, and the other end of the connecting piece 300 is rotatably installed with a clamping block 100. The clamping block 100 is rotatably installed with the hollow shaft head 400. When the central shaft 800 rises or falls, the connecting block 900 drives the connecting piece 300 to rotate, which in turn drives the clamping block 100 to rotate around the point where it is rotatably installed with the hollow shaft head 400, thus achieving the clamping or loosening of the clamping block 100. (See appendix) Figure 7The clamping surface 101 of the clamping block 100 is set as an arc surface. It should be noted that the axis of the arc surface is vertical. In addition, the clamping surface 101 of the clamping block 100 is also provided with a beveled surface 102. The beveled surface 102 is cut downward from the axis of the hollow shaft head 400 at an acute angle to the axis of the clamping surface 101. The purpose of setting the beveled surface 102 is to improve the adaptability of the clamping block 100 when clamping the bottle. A connecting part 103 is provided at the bottom of the arc surface. The connecting part 103 is provided with a fixed rotating shaft hole 104 and a rotating connecting hole 105. The fixed rotating shaft hole 104 is used for rotatable connection with the hollow shaft head 400, and the rotating connecting hole 105 is used for rotatable connection with the connecting piece 300.

[0041] The specific operation of the bottle rotating assembly disclosed in this application for loading, unloading, and rotating bottles is as follows: The bottle rotating assembly has several evenly arranged components mounted on the base. A cam is rotatably mounted on the base. The cam contacts a deep groove ball bearing on the outer protrusion of the lifting bearing seat 700 at the bottom of the central shaft 800. The rotation of the cam drives the central shaft 800 to rise and fall. When the central shaft 800 falls, the connecting block 900 falls, the connecting piece 300 retracts, and the clamping block 100 opens outward. At this time, the bottle is loaded. Under the elastic force of the elastic element 801, the central shaft 800 rises, the connecting block 900 rises, the connecting piece 300 moves outward, the clamping block 100 clamps, and the pulley 601 rotates under the action of external force, driving the spindle 600 to rotate. The spindle 600 drives the hollow shaft head 400, the central shaft 800, and corresponding components such as the clamping block 100 and the bottle support plate 200 to rotate synchronously, thereby realizing the bottle rotating action.

[0042] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
