Description

Technical Field

[0001] The utility model relates to the technical field of food and medicine packaging machinery and equipment, in particular to a container conveying detection device. Background Art

[0002] Most of the existing equipment with waste bottle rejection and bottle separation functions use pneumatic sorting, and there is no function to detect broken bottles at the bottle separation position. When broken bottles appear at the bottle separation port, it is impossible to accurately judge, resulting in continuous bottle breakage of the equipment. This state can only be released after manual discovery, causing a lot of waste in production.

[0003] The existing Chinese patent document with application number 201921547227.2 discloses a broken bottle alarm device, which specifically includes an insulating base plate; the front of the insulating base plate is provided with positive electrode strips and negative electrode strips arranged at intervals; the sides of the positive electrode strips are connected to each other and connected to the positive connection pole; the sides of the negative electrode strips are connected to each other and connected to the negative connection pole. When a bottle is broken, the liquid medicine in the bottle drips onto the insulating base plate, and the liquid medicine simultaneously contacts the positive electrode strips and the negative electrode strips to form a conductive loop, which is transmitted to the control system through two signal lines. The control system controls the alarm to send an alarm signal. However, this broken bottle alarm device has the following shortcomings:

[0004] 1) If the amount of liquid discharged is small and the signal between the positive electrode strip and the negative electrode strip is weak, the weak signal may be difficult to transmit to the control system to make the alarm sound. Therefore, it is easy to cause the bottle to break without sounding the alarm.

[0005] 2) The flip cover is opened and closed by a driving mechanism to achieve liquid discharge and liquid blocking, which has a complex structure and high manufacturing cost. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a container conveying detection device which has a simple structure and can avoid bottle breakage without alarming.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] A container conveying detection device includes a first container conveying mechanism, a second container conveying mechanism and a liquid detection mechanism for detecting liquid. The first container conveying mechanism is connected to the second container conveying mechanism. The liquid detection mechanism includes a liquid sensor and a signal amplifier. The liquid sensor is arranged below the intersection of the first container conveying mechanism and the second container conveying mechanism, and is connected to the signal amplifier to form a signal feedback circuit.

[0009] As a further improvement of the above technical solution:

[0010] The container conveying detection device further includes a PLC module, and the signal feedback circuit is connected to the PLC module.

[0011] The first container conveying mechanism and the second container conveying mechanism are both connected to the PLC module signal.

[0012] A purge mechanism is provided on one side of the liquid sensor for purging liquid on the liquid sensor.

[0013] The first container conveying mechanism and the second container conveying mechanism are both thumbwheel conveying mechanisms, and the signal amplifier is a triode.

[0014] The first container conveying mechanism includes a first paddle wheel and a first bottom plate, and the second container conveying mechanism includes a second paddle wheel and a second bottom plate. The first bottom plate and the second bottom plate are flush connected, the first paddle wheel is arranged above the first bottom plate, the second paddle wheel is arranged above the second bottom plate, the first paddle wheel and the second paddle wheel intersect, and the liquid sensor is arranged below the intersection of the first paddle wheel and the second paddle wheel.

[0015] The first dial wheel, the first bottom plate, the second dial wheel and the second bottom plate are all arranged horizontally.

[0016] The first container conveying mechanism is an auger conveying mechanism, and the second container conveying mechanism is a thumbwheel conveying mechanism.

[0017] The first container conveying mechanism includes an auger and a third bottom plate, and the second container conveying mechanism includes a third paddle wheel and a fourth bottom plate. The third bottom plate and the fourth bottom plate are flatly connected. The auger is arranged above the first bottom plate, and the third paddle wheel is arranged above the fourth bottom plate. The auger is connected to the third paddle wheel, and the liquid sensor is arranged below the connection between the auger and the third paddle wheel.

[0018] The auger, the third bottom plate, the third pulley and the fourth bottom plate are all arranged horizontally.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] In this new container conveying detection device, when a container breaks or leaks, the leaked liquid drips onto the liquid sensor below, causing it to emit a sensing signal. This sensing signal is amplified by a signal amplifier and then transmitted to an external control system, triggering an alarm. This amplification prevents weak signals from being transmitted to the external control system and causing the alarm to sound, thus preventing the situation where a broken bottle fails to sound an alarm.

[0021] The container conveying detection device of the utility model cleans the liquid on the liquid sensor through the cleaning mechanism, has a simple structure and low manufacturing cost. BRIEF DESCRIPTION OF THE DRAWINGS

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0031] In this utility model, unless otherwise specified or limited, the terms "assemble," "connect," "connect," "fix," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components.
