[0003] The existing bottle cap outer side detection device is linear conveying bottle cap, and a plurality of cameras are arranged on both sides of the conveying line to carry out detection, but even so, there is still a detection blind area in the conveying direction. Therefore, the inventor designs a wheel disc type bottle cap detection equipment, which continuously inputs and outputs bottle caps to the wheel disc mechanism through two star wheels, so that the bottle caps revolve with the wheel disc mechanism to pass through the image acquisition mechanism, the image acquisition mechanism rotates synchronously with the wheel disc mechanism by a preset angle to complete image acquisition, and the bottle caps also rotate at the same time to enable the image acquisition mechanism to obtain complete images of the side of the bottle caps. In order to meet the requirement that the wheel disc type bottle cap detection equipment makes the bottle caps revolve and rotate at the same time, and enables the bottle caps to continuously move and be detected, the inventor specially designs a wheel disc type bottle cap conveying mechanism. UTILITY MODEL CONTENTS

[0004] To solve the technical problems in the background art, the utility model provides a wheel disc type bottle cap conveying mechanism.

[0005] The utility model technical scheme is as follows:

[0006] A wheel disc type bottle cap conveying mechanism is arranged on a platform and comprises a wheel disc assembly, a cap supporting assembly, a cap pressing assembly and a lifting assembly.

[0007] The wheel disc assembly is connected to the platform and can rotate horizontally.

[0008] The cap supporting assembly comprises a tray, the tray is connected to the wheel disc assembly and can rotate horizontally, and the top of the tray is used for supporting the bottle cap.

[0009] The cap pressing assembly is located directly above the cap supporting assembly, the cap pressing assembly comprises a cap pressing rod slidingly connected to the wheel disc assembly, and the lower end of the cap pressing rod is rotatably connected to a pressing head.

[0010] The lifting assembly is used for driving the cap pressing rod to vertically slide.

[0011] Through the cap pressing assembly and the cap supporting assembly, the bottle cap is clamped, the bottle cap revolves with the wheel disc assembly, and the bottle cap rotates under the driving of the tray rotation, thereby realizing continuous and uninterrupted conveying and comprehensive detection of the bottle cap outer side detection.

[0012] Furthermore, there are multiple cover supports and multiple cover presses, which are arranged in a ring around the rotation axis of the wheel assembly. The number of cover presses and cover supports are the same, and they are arranged in a vertically corresponding manner.

[0013] Furthermore, the pressure rod is provided with a push rod that extends radially outward toward the wheel assembly. A spring is connected between the push rod and the wheel assembly. The lifting assembly includes a cam strip with a convex top surface. The push rod is configured to slide along the top surface of the cam strip and be lifted when it rotates with the wheel assembly.

[0014] In some embodiments, the roulette wheel assembly includes a lower roulette wheel and an upper roulette wheel frame. The lower roulette wheel is connected to a platform and is capable of horizontal rotation. The upper roulette wheel frame is connected above the lower roulette wheel and rotates synchronously with the lower roulette wheel. A cover assembly is connected to the lower roulette wheel, and a cover assembly is connected to the upper roulette wheel frame.

[0015] The upper wheel frame includes an upper plate and a lower plate, and an annular vertical plate connecting the two plates. The pressure rod is slidably connected to the two plates. The vertical plate has limiting holes corresponding to the positions of each pressure rod. The push rod slides vertically in the limiting holes. The lower plate is connected to the lower wheel through several support rods. The limiting holes provide a limiting function for the up and down sliding of the pressure rod.

[0016] Furthermore, the pressure rod is located inside the vertical plate, and the cam strip is located outside the vertical plate.

[0017] Furthermore, the push rod is perpendicular to the pressure plate rod, with one end connected to the pressure plate rod and the other end equipped with a follower wheel that can contact the top surface of the cam strip. The use of a follower wheel converts the friction between the push rod and the cam strip into rolling friction, reducing frictional resistance and loss, and improving the lifespan of the push rod.

[0018] Furthermore, the push rod is equipped with a rolling bearing, which is located in and slidably engaged with the limiting hole. The rolling bearing not only prevents the push rod from rotating horizontally when the bottle cap rotates, but also converts the friction between the push rod and the limiting hole into rolling friction, reducing frictional resistance during sliding.

[0019] Furthermore, the lower plate is equipped with downward-extending linear bearings corresponding to each capping rod position, with the capping rod slidingly engaged with the linear bearings. The linear bearings reduce the frictional resistance during the sliding of the capping rod and also provide guidance, ensuring that the capping rod accurately presses onto the bottle cap.

[0020] Furthermore, the wheel-type bottle cap conveying mechanism also includes a self-rotating drive assembly, which is set on the platform. The self-rotating drive assembly includes a timing belt, a rotating rod is provided under the tray, the rotating rod is rotatably connected to the wheel assembly, and a timing pulley is provided on the rotating rod. The timing belt can drive the rotating rod to rotate through the timing pulley.

[0021] This utility model provides a rotary bottle cap conveying mechanism that, through a cap pressing assembly and a cap holding assembly, can clamp the bottle cap and rotate it together with the rotary assembly, realizing the bottle cap's revolution and rotating it to the detection position. At the same time, the bottle cap can also rotate with the tray, so that the bottle cap rotates while passing through the image acquisition mechanism, allowing the image acquisition mechanism to obtain a complete image of the side of the bottle cap. This enables the rotary assembly to move the bottle cap continuously without stopping, improving the bottle cap detection efficiency. Attached Figure Description

[0027] like Figure 1 and Figure 2 As shown, this utility model provides a disc-type bottle cap conveying mechanism, applied to a disc-type bottle cap inspection device, used to convey bottle caps when inspecting defects on the outer surface of the bottle caps. The disc-type bottle cap inspection device includes a platform for mounting the various components.

[0028] The wheel-type bottle cap conveying mechanism is set on the platform and includes a wheel assembly 1, a cap support assembly 2, a cap pressing assembly 3, and a lifting assembly 4;

[0029] The wheel assembly 1 is connected to the platform and can rotate horizontally;

[0030] The cap support assembly 2 includes a tray 21, which is connected to the wheel assembly 1 and is capable of horizontal rotation, with its top used to support the bottle cap;

[0031] The cap assembly 3 is located directly above the cap support assembly 2. The cap assembly 3 includes a cap rod 31 that is vertically slidably connected to the wheel assembly 1. A pressure head 32 is rotatably connected to the lower end of the cap rod 31.

[0032] The lifting assembly 4 is used to drive the pressure plate rod 31 to slide vertically.

[0033] The bottle cap is clamped by the capping assembly 3 and the cap holding assembly 2, so that the bottle cap revolves with the wheel assembly 1. At the same time, the bottle cap rotates under the drive of the tray 21, thereby realizing continuous and uninterrupted conveying and comprehensive inspection of the outer surface of the bottle cap.

[0034] The technical solution of this application will be described in detail below with specific embodiments.

[0035] The roulette wheel assembly 1 includes a lower roulette wheel 11 and an upper roulette wheel frame 12. The lower roulette wheel 11 is connected to a platform (not shown in the figure), and the platform is equipped with a drive mechanism for driving the lower roulette wheel 11 to rotate horizontally. The lower roulette wheel 11 is disc-shaped, the cover assembly 2 is connected to the lower roulette wheel 11, and the pressure cover assembly 3 is connected to the upper roulette wheel frame 12. The upper roulette wheel frame 12 is connected above the lower roulette wheel 11 and rotates synchronously with the lower roulette wheel 11.

[0036] Multiple cover assemblies 2 and multiple cover pressing assemblies 3 are provided, arranged in a ring around the rotation axis of the wheel assembly 1. The number of cover pressing assemblies 3 and cover assemblies 2 are the same, and they correspond to each other vertically.

[0037] The upper wheel frame 12 includes an upper plate 121 and a lower plate 122 arranged vertically, and an annular vertical plate 123 connecting the two plates. The lower plate 122 is connected to the lower wheel 11 by several vertical support rods 124. Both the upper plate 121 and the lower plate 122 are annular horizontal plates to save materials, reduce the weight of the wheel assembly 1, and make the start and stop of the wheel assembly 1 smoother and faster. The outer edges of the upper plate 121 and the lower plate 122 are preferably connected to the upper and lower edges of the vertical plate 123.

[0038] The capping rod 31 is slidably connected to two flat plates. The lower flat plate 122 is provided with a downwardly extending linear bearing 125 corresponding to the position of each capping rod 31. The capping rod 31 is slidably engaged with the linear bearing 125. The linear bearing 125 can reduce the frictional resistance when the capping rod 31 slides, and at the same time, it also provides a guiding function for the capping rod 31, ensuring that the capping rod 31 is accurately pressed onto the bottle cap.

[0039] The pressure rod 31 is also equipped with a push rod 33, which is perpendicular to the pressure rod 31. One end of the push rod 33 is connected to the pressure rod 31, and the other end extends radially outward towards the wheel assembly 1. A spring 34 connects the push rod 33 and the wheel assembly 1. The lifting assembly 4 includes a cam strip 41, whose two ends are fixed to the platform by columns, so that the height of the cam strip 41 corresponds to the height of the push rod 33. The top surface of the cam strip 41 is convex, and when the push rod 33 rotates with the wheel assembly 1, it can slide along the top surface of the cam strip 41 and be lifted. When the push rod 33 slides past the cam strip 41, the push rod 33 drives the pressure rod 31 to move downward under the action of the spring 34.

[0040] A follower wheel 35 is provided on the outward extension end of the push rod 33 for contacting the top surface of the cam strip 41. By setting the follower wheel 35, the friction between the push rod 33 and the cam strip 41 is converted into rolling friction, reducing frictional resistance and frictional loss, and improving the service life of the push rod 33.

[0041] The cam bar 41 extends horizontally in an arc shape and is close to the outer side of the vertical plate 123 of the upper wheel plate frame 12. Its central axis is collinear with the rotation axis of the upper wheel plate frame 12.

[0042] The top surface of the cam bar 41 can be trapezoidal. In this embodiment, the top surface of the cam bar 41 includes seven segments extending sequentially: a first upper inclined surface, a first buffer plane, a second upper inclined surface, a top plane, a first lower inclined surface, a second buffer plane, and a second lower inclined surface. The cam bar 41 is horizontally symmetrical.

[0043] The follower wheel 35 rotates with the wheel assembly 1, first contacting the first upper inclined surface and rising along the inclined surface to raise the capping assembly 3, causing the capping assembly 3 to release its grip on the bottle cap. It then slides along the first buffer plane; during this process, the bottle cap is rotated out of the wheel-type bottle cap conveying mechanism by the star disk. The follower wheel 35 then slides along the second upper inclined surface and the top plane, further raising the height of the capping assembly 3, providing space for another star disk to place the bottle cap onto the tray 21. The position where the follower wheel 35 slides on the top plane corresponds to the bottle cap placement position. The follower wheel 35 then slides down the first lower inclined surface, the second buffer plane, and the second lower inclined surface, causing the capping assembly 3 to press onto the bottle cap. The second buffer plane acts as a descent buffer, preventing the capping assembly 3 from descending too high or too quickly at once, which could easily topple or misalign the bottle cap.

[0044] The vertical plate 123 is provided with limiting holes 1231 corresponding to the positions of each pressure rod 31. The pressure rod 31 and the cam strip 41 are located on the inner and outer sides of the vertical plate 123, respectively. The push rod 33 passes through the limiting hole 1231 and slides vertically within the limiting hole 1231. The limiting hole 1231 provides a limiting function for the up and down sliding of the pressure rod 31. It is strip-shaped and extends vertically.

[0045] The push rod 33 is also equipped with a rolling bearing 36, which is located in the limiting hole 1231 and slides in fit with the limiting hole 1231. The rolling bearing 36 not only prevents the push rod 33 from rotating horizontally when the bottle cap rotates, but also converts the friction between the push rod 33 and the limiting hole 1231 into rolling friction, reducing frictional resistance and wear during sliding.

[0046] The outer diameter of the rolling bearing 36 is preferably slightly smaller than the width of the limiting hole 1231, so that when the rolling bearing 36 slides in the limiting hole 1231, it only rubs against one side wall of the limiting hole 1231, ensuring that the capping rod 31 slides smoothly, and also preventing the push rod 33 from shaking a large range under the action of the bottle cap rotation, which would affect the firmness of the bottle cap clamping.

[0047] Spring 34 is fitted onto capping rod 31, with its two ends abutting against push rod 33 and upper plate 121 respectively. When capping rod 31 slides upward, spring 34 is compressed. Preferably, spring 34 is always compressed, that is, when capping rod 31 slides down to the lowest position, spring 34 is still compressed, so as to provide a preload force to capping rod 31, so that capping rod 31 has stable pressure when pressing on bottle cap, ensuring the firmness of bottle cap clamping.

[0048] The capping head 32 connected to the lower end of the capping rod 31 includes a bearing seat 321 and a nylon tip 322. The bearing seat 321 is rotatably connected to the lower end of the capping rod 31. The nylon tip 322 is installed at the lower end of the bearing seat 321 and is detachable to facilitate replacement of worn nylon tips 322 and ensure the secure clamping of the bottle cap. The nylon tip 322 is provided with a vent hole that connects to the bearing seat 321.

[0049] The nylon tap 322 has a first slot on its bottom surface, and the tray 21 is also preferably made of nylon, with a second slot on its top surface. Both the nylon tap 322 and the tray 21 are made of nylon, which prevents the bottle cap from being damaged by contact with hard metal, and is also low in manufacturing cost and easy to replace. The first and second slots are used to position and limit the bottle cap, so that the bottle cap can be fixed in the correct position and firmly clamped.

[0050] Each cover assembly 2 is provided with a seated bearing 111 on the lower wheel 11, and a rotating rod 22 is provided on the lower side of the tray 21. The rotating rod 22 is rotatably connected to the seated bearing 111.

[0051] The wheel-type bottle cap conveying mechanism also includes a rotation drive assembly 5, which is mounted on the platform. The rotation drive assembly 5 includes a timing belt 51, and the lower end of the rotating rod 22 extends downwards from the bottom surface of the lower wheel 11, with a timing pulley 23 at the lower end. The timing belt 51 can drive the rotating rod 22 to rotate via the timing pulley 23 of the cap support assembly 2, thereby causing the tray 21 and the bottle caps on the tray 21 to rotate. This rotation drive assembly 5 has a simple structure and can simultaneously rotate multiple trays 21.

[0052] In use, the timing pulley 23 rotates with the lower pulley 11 until it contacts the timing belt 51. As the lower pulley 11 continues to rotate, the timing pulley 23 rotates relative to the timing belt 51, thus achieving rotation.

[0053] In this embodiment, the platform is provided with several idler wheels 52. The idler wheels 52 are located outside the wheel assembly 1 and below the cam strip 41. The timing belt 51 is fitted on several timing pulleys 23 and several idler wheels 52. With the support of the idler wheels 52, the portion of the timing belt 51 corresponding to the cam strip 41 below does not contact the timing belt 51, and the cap support assembly 2 stops rotating, so that the star wheel can rotate the bottle cap out or rotate the bottle cap into the cap support assembly 2.

[0054] The timing belt 51 can be set to be fixed, but in this embodiment, the platform drive motor 53 drives the timing belt 51 to rotate. When the timing belt 51 and the wheel assembly 1 rotate in the same direction, the bottle cap rotates slower. When the timing belt 51 and the wheel assembly 1 rotate in opposite directions, the bottle cap rotates faster. This allows the bottle cap's rotation speed to be adjusted according to actual needs.
