Description
Technical Field
The utility model relates to the technical field of automatic bottle detection, in particular to a constant-speed holding mechanism for a tray of detection equipment.
Background
In the production line of a wine enterprise, before the wine is filled, whether the bottle body has leakage or not needs to be detected. For the milk glass bottle which is often used as a wine bottle, the traditional human eye observation detection mode is not applicable any more because the whole body of the milk glass bottle is milky and non-transparent, and cracks are difficult to observe by naked eyes.
Currently, there are two ways of automatically detecting leakage of a bottle in the prior art, one way is to inflate the bottle, as described in CN208606972U, if there is a crack in the bottle, the glass bottle will be blown out or leaked, but this way is not safe and the detection of other bottles is easily affected. Another method is described in CN210825346U, in which the bottle is knocked and judged according to the tone color transmitted from the bottle, but this method is greatly affected by the wall thickness of the bottle and the position of the crack, and the person to be detected needs to have a lot of experience, so that the method is inconvenient to popularize.
Therefore, the applicant designs an automatic bottle leakage detection device, which is characterized in that a vertical high-voltage electrode is arranged outside a bottle body, water is sprayed at a position corresponding to the electrode on the inner wall of the bottle in a vertical manner, the water is grounded, and if a crack exists on the bottle body between the electrode and the water, charges can move in the crack, so that the bottle body is communicated with the outside to generate current, and the principle that whether the crack exists in the bottle body is utilized. The detection mode has high detection precision, does not damage the bottle body, and has higher automation degree by collecting current information through the detection unit and transmitting the current information to the processing unit for analysis and judgment.
In the detection equipment, the detection equipment can drive a tray arranged on the detection equipment and a bottle body borne on the tray to rotate around the central shaft of the equipment through the central rotating mechanism so as to realize continuous operation of detection, meanwhile, the tray can also be driven to rotate automatically to enable the bottle body borne by the tray to rotate so as to detect the whole bottle wall, the rotation speed of the tray is influenced by the rotation speed of the central rotating mechanism, the rotation speed of the detection equipment can be changed according to the quantity of the bottle bodies accumulated in the next assembly line procedure, and the rotation of the bottle body can be enabled to be faster and slower. In order to ensure the accuracy of detection, the bottle body is prevented from rotating too fast or too slow to influence the detection result, so that the bottle body is required to keep rotating at a constant speed during detection, but the problem cannot be solved in the prior art, and therefore, the applicant designs a tray constant-speed maintaining mechanism of the detection equipment.

Referring to fig. 3, the tray constant speed holding mechanism 1 includes a driving wheel 11, at least two driven wheels 12, a tensioning wheel 13, a belt 14, a speed detecting unit and a control unit.
In this description, in the present embodiment, the speed detecting unit and the control unit are mounted on the detecting apparatus, and thus are not shown in the drawing. The speed detection unit detects the rotation speed of the center frame 2, and the control unit is respectively connected with the speed detection unit and the motor 5 to control the rotation speed of the motor 5.

The speed detecting unit detects the rotational speed of the steady rest 2 and transmits the detected information to a control unit connected thereto, which compares the obtained rotational speed of the steady rest 2 with a preset rotational speed.
If the rotation speed of the central frame 2 is the same as the preset speed, the control unit does not send out an instruction, and at the moment, the tray constant-speed holding mechanism 1 is static, the central frame 2 rotates to drive the connecting shaft 4 and the tray 3 connected with the connecting shaft to rotate around the axis of the central frame 2, and the connecting shaft 4 is matched with the belt 14, so that the connecting shaft 4 can drive the tray 3 to rotate around the axis of the central frame at the preset rotation speed;
if the rotation speed of the center frame 2 is higher than the preset speed, the control unit controls the motor 5 connected with the center frame to rotate positively, the driving wheel 11 drives the belt 14 and the tray 3 to move in the same direction, but the moving speed of the belt 14 is lower than the moving speed of the tray 3, and the tray 3 still rotates at the preset rotation speed through the moving speed difference of the tray 3 and the belt 14;
if the rotation speed of the center frame 2 is slower than the preset speed, the control unit controls the motor 5 to reversely rotate, and the driving wheel 11 drives the belt 14 and the tray 3 to reversely move, so as to compensate the rotation speed of the tray 3, and the tray 3 can still rotate at the preset rotation speed.
Specifically, in this embodiment, the driving wheel 11, the tensioning wheel 13 and at least two driven wheels 12 are all mounted on the frame through mounting seats 15, and are all rotatably connected with the respective mounting seats 15. The driving wheel 11, the tensioning wheel 13 and the at least two driven wheels 12 are positioned at the same horizontal height, the axes of the driving wheel 11, the tensioning wheel 13 and the at least two driven wheels 12 are parallel to the axis of the connecting shaft 4, and the belt 14 is sleeved on the driving wheel 11, the tensioning wheel 13 and the at least two driven wheels 12.

Further, a plurality of equidirectional moving grooves 151 are formed in the mounting seat 15 of the tensioning wheel 13, bolts penetrate through the moving grooves 151 and are connected with the frame, and the bolts can slide in the moving grooves 151. After the belt 14 is tensioned by moving the mount 15 of the tensioner 13, the position of the mount 15 of the tensioner 13 is fixed by bolts.
In this embodiment, the belt 14 is preferably a timing belt with teeth facing outwardly. Preferably, the connecting shaft 4 is connected with a synchronizing wheel 6, the synchronizing wheel 6 is matched with the outer side face of the synchronizing belt, and the synchronizing belt drives the connecting shaft 4 to drive the tray 3 to rotate.

The moving area where the synchronous belt and the synchronous wheel 6 are in a matched state generally corresponds to the detecting area, in this embodiment, the rotation angle of the tray 3 around the axis of the central frame 2 is preferably 180 degrees in the rotation time, that is, from the time when the synchronous wheel 6 is matched with the synchronous belt, the tray 3 is driven to rotate, detection is started, until the synchronous wheel 6 is disengaged from the synchronous belt, the tray 3 stops rotating, the detection is completed, and the rotation angle of the tray 3 is 180 degrees.
Further, the driving wheel 11 is connected with the outer side surface of the synchronous belt, and teeth meshed with the synchronous belt teeth are arranged on the surface of the driving wheel 11, so that acting force between the driving wheel 11 and the synchronous belt is increased, and the rotating speed of the driving wheel 11 is effectively transmitted to the synchronous belt.

For the driving wheel 11, because it needs to provide power for the movement of the synchronous belt, the larger the contact area between the driving wheel 11 and the synchronous belt is, the more favorable the power transmission is, so two of the driven wheels 12 in the embodiment are arranged beside the driving wheel 11, and the bending angle of the synchronous belt on the driving wheel 11 is close to, equal to, or even larger than 180 degrees.
