Technical Field
[0001] The utility model relates to the technical field of granule counting machines, in particular to a recheck weighing device for an electronic granule counting machine. Background Art
[0002] Electronic granule counting machines are commonly used in fields such as food, health food, and pharmaceuticals. An electronic granule counting machine is a high-tech medicine counting and filling device integrating optoelectromechanics, and is widely used in industries such as pharmaceuticals, food, and chemical engineering. Its structural characteristics and working principles are as follows: Feeding hopper: used to store the items to be counted to ensure continuous and stable material supply. Vibration conveying device: makes the material move along a specific path through vibration to ensure uniform and continuous conveying of the material. Discharging device: responsible for discharging the processed material according to the set quantity to complete the tasks of counting and filling. These structures work together to enable the electronic granule counting machine to efficiently and accurately complete the counting and filling of granular items such as medicines or foods.
[0003] The net content of traditional electronic granule counting machines is usually controlled by measuring the total weight of the filled bottles by a weighing device to control the net content of the product; therefore, the existing granule counting machines have many defects. One is that since the weight of each bottle is not uniform and constant, the net content deviation measured by this operation procedure is too large, and unqualified products such as too many or too few granules are likely to appear, which is not conducive to product quality control; the other is that when unqualified products appear, manual intervention is required to remove the unqualified products, and production automation cannot be achieved, affecting production efficiency. Content of the Utility Model
[0004] The purpose of the utility model is to solve the technical problems existing in the prior art, and provides a recheck weighing device for an electronic granule counting machine, which can make the product quality stable and controllable, and at the same time improve production efficiency.
[0005] To achieve the above object, the utility model adopts the following technical solutions: An electronic tablet counting machine rechecking and weighing device, which includes a weighing base, a reset scale and a weighing bracket. The reset scale is arranged on the weighing base, the weighing bracket is arranged above the reset scale, a third conveyor belt is arranged above the weighing bracket, and the third conveyor belt is arranged directly below the tablet counting hopper of the electronic tablet counting machine. A first conveyor belt and a second conveyor belt are respectively arranged on both sides of the third conveyor belt along the length direction. An in-bottle reset sensor is arranged on one side along the width direction directly below the tablet counting hopper to detect whether there is an in-bottle signal. The in-bottle reset sensor is connected to a control processor. Railings are arranged on both sides of the first conveyor belt, the third conveyor belt and the second conveyor belt in the width direction. An in-bottle cylinder, a bottle-releasing cylinder and a waste-kicking cylinder are sequentially arranged on the railings to control the in-bottle, bottle-releasing and rejection of the bottles. The control processor is electrically connected to the reset scale, the tablet counting hopper and the waste-rejecting cylinder. After the control processor detects the in-bottle signal, it controls the reset scale to return to zero, and controls the tablet counting hopper of the electronic tablet counting machine to start counting. After the counting is completed, the reset scale weighs the net content of the material. The control processor compares the detected net content signal with the preset net content. Qualified products normally flow into the next process, and unqualified products output a waste-rejecting signal to the waste-kicking cylinder after counting and are rejected at the waste-kicking cylinder part.
[0006] A further solution of the utility model is that the in-bottle reset sensor is a photoelectric sensor, and the photoelectric sensor converts the optical signal of whether there is a bottle in into an electrical signal and transmits it to the processor.
[0007] A further solution of the utility model is that a transition plate is arranged between the tail end of the first conveyor belt and the head end of the third conveyor belt; a transition plate is arranged between the tail end of the third conveyor belt and the head end of the second conveyor belt to facilitate the smoother conveying of the bottles.
[0008] A further solution of the utility model is that the in-bottle cylinder is arranged on the railing between the first conveyor belt and the third conveyor belt, the bottle-releasing cylinder is arranged on the railing at the tail end of the third conveyor belt, and the waste-kicking cylinder is arranged on the railing at the head end of the second conveyor belt.
[0009] A further solution of the utility model is that the first conveyor belt, the second conveyor belt and the third conveyor belt are respectively driven to operate by a first motor, a second motor and a third motor.

Detailed Embodiments
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0019] The verification weighing device of the present utility model is used for improving the existing production line of electronic tablet counting machines and needs to be installed and designed on the conveyor belt of the original equipment.
[0020] As Figure 1 , Figure 2 shown, an electronic tablet counting machine verification weighing device includes a weighing base 4, a reset scale 5 and a weighing bracket 6.
[0021] The reset scale 5 is an electronic scale, which mainly consists of a load-bearing system (such as a scale pan and a scale body), a force transmission and conversion system (such as a lever force transmission system and a sensor), and a value indication system (such as a dial and an electronic display instrument). The scale body of the reset scale 5 is arranged on the weighing base 4. The weighing bracket 6 is arranged above the scale pan of the reset scale 5. A third conveyor belt 7 is arranged above the weighing bracket 6. The third conveyor belt 7 is arranged directly below the tablet counting hopper 1 of the electronic tablet counting machine. On both sides of the third conveyor belt 7 in the length direction, a first conveyor belt 2 and a second conveyor belt 3 are respectively arranged. A transition plate 16 is arranged between the tail end of the first conveyor belt 2 and the head end of the third conveyor belt 7; a transition plate 16 is arranged between the tail end of the third conveyor belt 7 and the head end of the second conveyor belt 3 to facilitate the smoother conveyance of the bottles.
[0022] The first conveyor belt 2 and the second conveyor belt 3 are formed by splitting the conveyor belts of the existing electronic tablet counting machine. The head and tail ends of the weighing base 4 are respectively fixed on the brackets of the first conveyor belt 2 and the second conveyor belt 3. The first conveyor belt 2, the second conveyor belt 3 and the third conveyor belt 7 are respectively driven to operate by a first motor 14, a second motor 15 and a third motor 8.
[0023] On one side in the width direction directly below the tablet counting hopper 1, a bottle inlet reset sensor 13 is arranged to detect whether there is a bottle inlet signal. The bottle inlet reset sensor 13 is connected to a control processor. Railings 9 are arranged on both sides of the first conveyor belt 2, the third conveyor belt 7 and the second conveyor belt 3 in their width directions. An inlet bottle cylinder 10, a bottle release cylinder 11 and a waste rejection cylinder 12 are successively arranged on the railings 9. The inlet bottle cylinder 10 is arranged on the railing 9 between the first conveyor belt 2 and the third conveyor belt 7. The bottle release cylinder 11 is arranged on the railing 9 at the tail end of the third conveyor belt 7. The waste rejection cylinder 12 is arranged on the railing 9 at the head end of the second conveyor belt 3. It is used to control the inlet, release and rejection of the bottles.
[0024] The control processor is electrically connected to the reset scale 5, the hopper 1 of the tablet counting machine, and the waste rejection cylinder 12. After the control processor detects the bottle inlet signal, it controls the reset scale 5 to return to zero, and controls the hopper 1 of the electronic tablet counting machine to start counting tablets. After counting is completed, the reset scale 5 weighs the net content of the material. The control processor compares the detected net content signal with the preset net content. Qualified products flow into the next process normally, and unqualified products output a waste rejection signal to the waste rejection cylinder 12 after counting, and are rejected at the position of the waste rejection cylinder.
[0025] In the present utility model, the circuit connection between the control processor and the control switch of the reset scale 5, the hopper 1 of the tablet counting machine, the bottle placing cylinder 11, and the switch of the waste rejection cylinder 12 is prior art. Those skilled in the art can achieve the above control functions according to each component and circuit, and this patent will not describe it.
[0026] The bottle inlet reset sensor 13 is a photoelectric sensor, and the photoelectric sensor converts the optical signal of whether a bottle enters into an electrical signal and transmits it to the processor.
[0027] A stop bar is provided at the front ends of the bottle inlet cylinder 10 and the bottle placing cylinder 11, and a ejector rod is provided at the front end of the waste rejection cylinder 12. The stop bars provided at the front ends of the bottle inlet cylinder 10 and the bottle placing cylinder 11 control the release of the bottles, and the ejector rod provided at the front end of the waste rejection cylinder 12 pushes the bottle away above the third conveyor belt 7.
[0028] Working principle:
[0029] The first motor 14 is turned on, and empty bottles are conveyed on the first conveyor belt 2. The bottle inlet cylinder 10 is turned on, and the stop bar of the bottle inlet cylinder 10 blocks the empty bottles and arranges the empty bottles in sequence on the first conveyor belt 2. After counting starts, the bottle inlet cylinder 10 contracts and then immediately extends. At this time, the bottle inlet cylinder 10 releases an empty bottle.
[0030] The empty bottle enters the third conveyor belt 7 after passing through the transition plate 16. The bottle inlet reset sensor 13 detects the bottle inlet signal and simultaneously transmits the bottle inlet signal to the control processor. The control processor controls the bottle placing cylinder 11 to extend, and the stop bar of the bottle placing cylinder 11 blocks the empty bottle so that the empty bottle is directly below the discharge port of the hopper 1 of the tablet counting machine.
[0031] At the same time, the control processor controls the reset scale 5 to return to zero. After returning to zero, the hopper 1 of the tablet counting machine starts counting tablets. After counting is completed, the reset scale 5 weighs the net content of the material. When the actual net content meets the preset standard net content, the product is directly output; when the actual net content does not meet the preset standard net content, the control processor sends a signal to the waste rejection cylinder 12, thereby starting the waste rejection cylinder 12 to reject the products with unqualified net content. Qualified products are conveyed to the second conveyor belt 3 and flow into the next process normally, and unqualified products are rejected at the waste rejection position of the second conveyor belt 3 after counting.
[0032] The utility model detects the bottle inlet signal through the bottle inlet reset sensor 13 and controls the reset scale 5 to zero, so as to obtain the accurate net content of the product, effectively solving the problem of deviation in net content detection during the production process, which leads to more or fewer grains in the bottling. The unqualified products are automatically removed through the rejection cylinder 12 by the control processor. Generally, the product quality can be made stable and controllable, and at the same time, the production efficiency can be improved.
[0033] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
