Whether there are defects such as scratches and dirt on the outer side of the bottle cap is an important content affecting the quality of wine products and the image of the enterprise, which needs to be strictly detected.
[0003] The existing detection device usually linearly conveys the bottle cap and arranges multiple cameras on both sides of the conveying line to obtain the image of the outer side of the bottle cap. However, there is still a detection blind area in the conveying direction. Therefore, the inventor designs a turntable type bottle cap detection equipment, which continuously conveys the bottle cap to the turntable frame through the star wheel, and the bottle cap revolves with the turntable frame. When entering the image acquisition mechanism acquisition range, the image acquisition mechanism will rotate synchronously with the bottle cap by a preset angle to complete the bottle cap image acquisition. The bottle cap revolves with the turntable frame and also rotates by itself to enable the image acquisition mechanism to obtain a complete image of the side of the bottle cap.
[0004] Since the bottle cap needs to rotate by itself on the turntable frame, in order to avoid the occurrence of tilting and other situations, the inventor of the present application designs a bottle cap fixing assembly. UTILITY MODEL CONTENT

DETAILED DESCRIPTION
[0027] As shown in Figure 1 and Figure 2 The utility model provides a kind of bottle cap fixing assembly, it is applied to rotating disc type bottle cap detection equipment, and detection equipment is equipped with rotating disc frame, and bottle cap fixing assembly is set on rotating disc frame, revolves around a fixed point with rotating disc frame.
[0028] The bottle cap fixing assembly comprises a cover supporting part 1 and a cover pressing part 2;
[0029] The cover supporting part 1 is rotationally connected to the rotating disc frame, and the top of the cover supporting part 1 is provided with a tray 11 for supporting the bottle cap.
[0030] The cover pressing part 2 is located directly above the cover supporting part 1, and comprises a sliding shaft 21, a pressing head 22 and a pushing member 23. The sliding shaft 21 is vertically slidably connected to the rotating disc frame, the pressing head 22 is rotationally connected to the lower end of the sliding shaft 21, and the pushing member 23 is arranged on the sliding shaft 21 and used for pushing the sliding shaft 21 to slide. The pushing member 23 is connected with the rotating disc frame through a spring 24.
[0031] The sliding shaft 21 is moved up and down through the pushing member 23, and the bottle cap is clamped and fixed through the pressing head 22 and the tray 11. At the same time, the pressing force of the pressing head 22 is provided through the spring 24, so that the firmness of the clamping and fixing of the bottle cap is improved, and the situation of the bottle cap being tilted is avoided.
[0032] The technical scheme of the present application will be described below in combination with specific embodiments and drawings:
[0033] As shown in the drawings, Figure 1 The rotating disc frame comprises a lower disc frame 3 and an upper disc frame 4 which rotate synchronously, the cover supporting part 1 is rotationally connected to the lower disc frame 3, and the upper disc frame 4 comprises a first flat plate 41 and a second flat plate 42 which are arranged in a vertical manner and a vertical plate 43 which is connected between the two flat plates. The sliding shaft 21 penetrates through the two flat plates and is slidably connected with the two flat plates.
[0034] The first flat plate 41 is provided with a flange bearing 411, and the second flat plate 42 is provided with a linear bearing 421 which extends downward from the second flat plate 42. The sliding shaft 21 is slidably matched with the flange bearing 411 and the linear bearing 421, so as to reduce the friction force when the sliding shaft 21 slides. In addition, the linear bearing 421 can also guide the sliding shaft 21.
[0035] In combination with Figure 2 As shown in the drawings, the pushing member 23 comprises a connecting seat 231 which is detachably fixedly connected with the sliding shaft 21. One side of the connecting seat 231 extends in a direction away from the sliding shaft 21 and has a connecting rod 233 which is perpendicular to the sliding shaft 21.
[0036] In the embodiment, a mode for driving the pushing rod 23 to vertically move is provided, that is, the rotating disc type bottle cap detection device is also provided with a cam mechanism (not shown in the drawings). The cam mechanism is fixed and does not move. When the pushing member 23 rotates with the rotating disc frame, the pushing member 23 can contact the cam mechanism and slide along the undulating surface of the cam mechanism. In the process of sliding, the pushing member 23 is lifted, and then the sliding shaft 21 is lifted. After the pushing member 23 slides through the cam mechanism, the sliding shaft 21 moves downward under the action of the spring 24 and presses on the bottle cap.
[0037] The pusher 23 also includes a follower wheel 232, which is rotatably connected to the extension end of the connecting rod 233 for sliding contact with the cam mechanism. The follower wheel 232 is used to cooperate with the cam mechanism. By using the follower wheel 232, the friction between the pusher 23 and the cam mechanism is converted into rolling friction, reducing frictional resistance and frictional loss, and improving the life of the pusher 23.
[0038] The vertical plate 43 is provided with a limiting hole 431. The limiting hole 431 is strip-shaped and extends vertically. The connecting rod 233 passes through the limiting hole 431 and slides in the limiting hole 431 to provide a limiting function for the up and down sliding of the sliding shaft 21.
[0039] The sliding shaft 21 and the follower wheel 232 are located on both sides of the vertical plate 43, respectively. A rolling bearing 234 is connected to the connecting rod 233. The rolling bearing 234 is located in the limiting hole 431 and slides in cooperation with the limiting hole 431. The rolling bearing 234 not only prevents the pusher 23 from rotating horizontally when the bottle cap rotates, but also converts the friction between the pusher 23 and the limiting hole 431 into rolling friction, reducing frictional resistance and wear during sliding.
[0040] The outer diameter of the rolling bearing 234 is preferably slightly smaller than the width of the limiting hole 431, so that when the rolling bearing 234 slides in the limiting hole 431, it only rubs against one side wall of the limiting hole 431, ensuring that the sliding shaft 21 slides smoothly, and also preventing the pusher 23 from shaking a large range under the action of the bottle cap's rotation, which would affect the firmness of the bottle cap clamping.
[0041] Spring 24 is sleeved on sliding shaft 21, with its upper and lower ends abutting against first plate 41 and connecting seat 231 respectively. Spring 24 is configured to be in a compressed state when pressure head 22 presses on bottle cap.
[0042] The lower end of the sliding shaft 21 is rotatably connected to the pressure head 22, and the upper end is provided with a limiting piece 25. The diameter of the limiting piece 25 is larger than the diameter of the sliding shaft 21. The limiting piece 25 cooperates with the limiting hole 431 to limit the sliding shaft 21 from sliding down.
[0043] The pressure head 22 includes a bearing housing 221 and a nylon tip 222. The bearing housing 221 is rotatably connected to the lower end of the sliding shaft 21. The nylon tip 222 is installed at the lower end of the bearing housing 221, and a first retaining groove 223 is provided on the bottom surface of the nylon tip 222. The nylon tip 222 and the bearing housing 221 are detachably connected to facilitate the replacement of worn nylon tip 222 and ensure the secure clamping of the bottle cap.
[0044] The cover component 1 includes a rotating shaft 12, which is rotatably connected to the turntable frame. Its upper end extends out of the lower plate frame 3, and the tray 11 is set on the upper end of the rotating shaft 12.
[0045] This embodiment provides a method for driving the tray 11 to rotate, that is, the lower end of the rotating shaft 12 extends out of the lower tray frame 3 and is provided with a synchronous pulley 13. The turntable bottle cap detection device is provided with a synchronous belt and a motor that drives the synchronous belt to rotate. When the synchronous pulley 13 revolves with the turntable frame, it will contact the synchronous belt within a certain angle range. Under the drive of the synchronous belt, the synchronous pulley 13 rotates, thereby driving the tray 11 and the bottle caps on the tray 11 to rotate.
[0046] In this embodiment, the lower plate frame 3 is provided with a seated bearing 31, and the rotating shaft 12 is rotatably connected to the lower plate frame 3 through the seated bearing 31.
[0047] Preferably, the tray 11 is made of nylon and is detachably connected to the pivot 12, and its top surface is provided with a second slot 111.
[0048] Both the nylon cap 222 and the tray 11 are made of nylon, which can prevent the cap from being crushed by contact with hard metal, and the manufacturing cost is low and the cap is easy to replace.
[0049] The first slot 223 and the second slot 111 are both used to position and limit the bottle cap, so that the bottle cap can be fixed in the correct position and firmly clamped.
[0050] This utility model provides a bottle cap fixing assembly. In use, before the bottle cap is inserted, the sliding shaft 21 slides upward under the action of the pushing member 23, raising the height of the pressing head 22 to provide space for the bottle cap. At this time, the spring 24 is compressed. After the bottle cap is placed on the tray 11, the pushing member 23 loses its upward force, and the sliding shaft 21 slides downward under the action of the spring 24, pressing the pressing head 22 against the top of the bottle cap. At this time, the spring 24 is still compressed, providing a clamping force to the pressing head 22, firmly fixing the bottle cap to the turntable frame and preventing the bottle cap from tipping over. Since the pressing head 22 is rotatably connected to the sliding shaft 21, and the cap-supporting component 1 is rotatably connected to the turntable frame, providing rotational drive to the cap-supporting component 1 or the pressing head 22, the bottle cap can rotate. Simultaneously, both the cap-supporting component 1 and the sliding shaft 21 rotate synchronously with the turntable frame, allowing the bottle cap fixing assembly to drive the bottle cap to revolve with the turntable frame.
