Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automatic packaging equipment, and in particular to a full-automatic particle counting packaging line. BACKGROUND

[0002] At present, many products such as medicines and foods need to be packaged by quantity in the production process, and granular materials that need to be accurately packaged need to be counted and packaged, which can ensure that the quantity of medicines is consistent with the packaging specifications and avoid medical accidents. In addition, compared with weighing and packaging, the particle counting machine can greatly improve the packaging efficiency in packaging.

[0003] The existing full-automatic particle counting packaging line mainly first conveys the material to the vibrating device through the storage tank and the conveying belt, then spreads the material through the vibrating device to avoid stacking of the material, so that the material is output one by one to the guide chute through the vibrating device, and then the material falls along the guide chute to the discharge hopper. A gap is left between the guide chute and the discharge hopper so that the recognition device can recognize the material falling from the guide chute to the discharge hopper and count it.

[0004] The existing technical solution in the above has the following defects: the material itself or in the transmission process may have defects, and the recognition device is mostly a particle counting sensor that calculates the quantity of products by induction, but it is difficult to identify and sort out the material with defects or weight out of specification. CONTENT OF THE UTILITY MODEL

[0005] The present application provides a full-automatic particle counting packaging line to detect the integrity of the material in the packaging process.

[0006] The above technical purpose of the present application is achieved by the following technical solution:

[0008] The weighing plate is a telescopic plate and is provided with multiple pieces, and the multiple pieces of weighing plates are respectively installed in the detection holes, the thickness of the weighing plate is less than the width of the detection hole, the upper plate surface of the weighing plate is fixedly connected with a weighing module, the weighing module measures the mass of the material, the outer end surface of the weighing plate in the contracted state is flush with the inner wall of the tank body, and the outer end surface of the weighing plate in the expanded state is attached to the opposite inner wall of the tank body.

[0009] The pushing plate is fixed to the plate surface of the box body opposite to the detection hole, the lower plate surface of the pushing plate is attached to the upper plate surface of the weighing plate, and the pushing plate in the extended state can be inserted into the detection hole.

[0010] By adopting the above technical scheme, the material falling device body disperses and counts the material falling into the plurality of material channels, the material falls to the weighing plate, the weighing module weighs the material, and whether the material is in compliance is judged according to the set value; when the material is in compliance, the pushing plate remains stationary, the weighing plate retracts to make the material fall to the discharge hopper and enter the packaging line body. When the material is not in compliance, the weighing plate remains in the extended state, the pushing plate extends to push the material on the weighing plate into the detection hole for recycling, and the material falling device records the number of the material falling this time and eliminates the recorded value, thereby completing further detection of the material and facilitating sorting of the non-compliant material.

[0011] Optionally, a plurality of lifting plates are fixed to the plate surface of the box body away from the detection hole, the lifting plates are fixed above the detection hole, and the lower end surface of the lifting plate can be higher than the upper edge of the detection hole and can be attached to the upper end surface of the weighing plate.

[0012] By adopting the above technical scheme, the falling state of the lifting plate can close the detection hole, so that the falling material cannot easily fall into the detection hole, thereby ensuring the accuracy of detection and counting.

[0013] Optionally, the width of the weighing plate is greater than the distance between the two adjacent partition plates and is obliquely installed in the detection hole, and the two side walls of the weighing plate are attached to the outer walls of the two adjacent partition plates.

[0014] By adopting the above technical scheme, the weighing plate is inclined, so that the material falling to the weighing plate slides to the side with lower inclination, thereby making it easier for the material to fall from the weighing plate to the discharge hopper.

[0015] Optionally, the width of the weighing module is less than the width of the weighing plate, and the weighing module is horizontally installed on the upper plate surface of the side with lower inclination of the weighing plate, and the length of the weighing module is equal to the width of the box body.

[0016] By adopting the above technical scheme, when the material falls to the weighing plate, it first falls to the plate surface of the weighing plate and then slides to the weighing module along the inclined surface of the weighing plate, so that the material does not directly fall to the weighing module, thereby protecting the weighing module, and the horizontal installation of the weighing module facilitates accurate counting during weighing.

[0017] Optionally, a receiving hole is provided below the detection hole, an adaptive buffer plate is installed in the receiving hole, the buffer plate is a telescopic plate, the outer end of the buffer plate in the retracted state is flush with the inner wall of the box body, and the outer end surface of the buffer plate in the extended state is attached to the opposite inner wall of the box body.

[0018] By adopting the above technical scheme, the weighing plate judges the material falling on the buffer plate to be compliant. Since the number of materials falling on the weighing plate each time is different, the number of materials falling on the packaging line body each time is consistent through the cooperation between the buffer plates.

[0019] Optionally, the buffer plate is obliquely installed in the containing hole, and the two side walls of the buffer plate are in close contact with the outer walls of the two adjacent partition plates.

[0020] By adopting the above technical scheme, the materials on the buffer plate are more easily separated and fall into the discharge hopper.

[0021] Optionally, the end face of the pushing plate in the retracted state is flush with the inner wall of the box.

[0022] By adopting the above technical scheme, the materials falling from the number-of-pieces line body to the weighing plate will not fall on the end face of the pushing plate, thereby facilitating the accuracy of detection.

[0023] Optionally, the box is fixedly connected with a discharge hopper at the lower end, the discharge hopper is in the shape of a funnel, the width of the top end of the discharge hopper is equal to the width of the box, and the bottom end is a round opening and located above the packaging line body.

[0024] By adopting the above technical scheme, the discharge end of the discharge hopper is located above the packaging material of the packaging line body, so that the falling materials fall into the packaging material, thereby avoiding secondary packaging and improving the packaging efficiency.

[0025] In summary, the present application has the following technical effects:

[0026] 1. The weighing plate is provided to judge the integrity of the material by weighing;

[0027] 2. The lifting plate installed at one end of the detection hole is provided, so that the materials falling from the number-of-pieces line body to the material buffer box will not fall into the detection hole;
