Description

Novel electronic combined scale

Field of the technology

The invention relates to an electronic combination scale, in particular to an electronic combination scale in the field of food packaging machinery.

Background

The packaging of marinated food products in general factories has been basically completed by highly mechanized vacuum packaging machines. In the packaging process, the weighing link of the materials is very important, and if the weighing is not accurate, the quality monitoring bureau is not passed, and huge loss can be caused to manufacturers. At present, the common packing machine adopts an electronic combination scale to weigh. The general electronic combination scale comprises a material distribution disc, discharge chutes are arranged on the periphery of the material distribution disc, pickles are poured on the material distribution disc and then distributed to the discharge chutes through the material distribution disc, materials fall into a buffer hopper through the discharge chutes, weighing hoppers are arranged below the buffer hoppers, the materials fall into the weighing hoppers from the buffer hoppers for weighing, the weighing hoppers are used for weighing to obtain data, the materials are combined into materials with set weight together with the materials in other weighing hoppers, then the materials fall into a collecting hopper below the collecting hopper, and the collecting hopper falls the materials into a packaging bag. It can be seen that to obtain a material with a set weight, the weights of a plurality of weighing hoppers are reasonably combined, for example, the weight of the package is set to be 100 g, one weighing hopper weighs 60 g, the other weighing hopper weighs 40 g, and thus the two weighing hoppers weigh 100 g after collecting the material and just meet the weight of the package. However, due to the insufficient number of weighing hoppers (the greater the number, the more likely the combination is), there is also the possibility that two of them will not always be combined to the set package weight.

Detailed Description

As shown in fig. 1 and 2, the novel electronic combination scale comprises a material distribution disc 1, wherein discharge chutes 2 are arranged at the periphery of the material distribution disc 1, discharge ports of the discharge chutes 2 are positioned above a buffer hopper 3, and an upper weighing hopper 4 is arranged right below the buffer hopper 3, which is the prior art. In order to obtain more combination modes, as shown in fig. 2 and fig. 3, a material distribution hopper 5 is arranged under an upper weighing hopper 4, a memory hopper 6 or a lower weighing hopper (that is, the memory hopper 6 can be arranged under the material distribution hopper 5, and the lower weighing hopper can also be arranged, wherein the memory hopper 6 is a common hopper, has the same structure as the buffer hopper 3 and does not have the weighing function, while the lower weighing hopper has the same structure as the upper weighing hopper 4 and has the weighing function), the material distribution hopper 5 can be rotatably arranged, the material distribution hopper 5 is in transmission connection with a material distribution power source for driving the material distribution hopper 5 to rotate, and the material distribution hopper 5 has a first state (shown in fig. 5) for guiding materials into the memory hopper 6 or the lower weighing hopper and a second state (shown in fig. 6) for guiding the materials to the outside through the driving of the material distribution power source; certainly, in order to control the blanking, the discharge hole of the buffer hopper 3, the discharge hole of the upper weighing hopper 4, and the discharge hole of the memory hopper 6 or the lower weighing hopper are all provided with an opening and closing mechanism, and the opening and closing mechanism comprises an opening and closing plate 8 and an opening and closing power source for driving the opening and closing plate 8 to open and close (the opening and closing mechanism is in the prior art, and can refer to patent application No. CN 201721397584.6).

The following description is given to the working principle of the weighing hopper 4 and the memory hopper 6 by taking the structure as an example: during operation, food material falls on minute charging tray 1, vibration or rotation through minute charging tray 1 lets the material on minute charging tray 1 enter into a plurality of blown down tank 2 of minute charging tray 1 periphery gradually, the material in blown down tank 2 just falls in buffer memory fill 3 through pushing away the material screw rod or the mode of vibration, the mechanism that opens and shuts of buffer memory fill 3 is opened, let the material fall in last weighing fill 4, go up weighing fill 4 and weigh and obtain data, and with data storage PLC (for prior art), the mechanism that opens and shuts of last weighing fill 4 is opened simultaneously, let the material fall in minute charging tray 5, when memory fill 6 of below does not deposit the material, divide the discharge gate that material power source drive minute charging tray 5 to rotate to directly over memory fill 6, as shown in figure 5, the material in minute charging tray 5 just can fall in memory fill 6 like this, because last weighing fill 4 weighs material weight, the material weight that falls in memory fill 6 is just recorded (is deposited PLC), then buffer memory fill 3 continues to fall the material in last weighing fill 4, just can make up and carry out the combination between a plurality of circles of weighing fill 6. During combination, the material distributing power source drives the material outlet of the material distributing hopper 5 to rotate to the outside, as shown in fig. 6, so that the material can be distributed to the outside through the material distributing hopper 5 by the upper weighing hopper 4 to be combined with the material in the memory hopper 6, and after combination is completed, the material falls into the packaging bag through the material collecting hopper 7. Through the structure, the upper round and the plurality of upper weighing hoppers 4 can be combined, the lower round and the plurality of memory hoppers 6 can also be combined, and meanwhile, the upper weighing hoppers 4 and the memory hoppers 6 can also be combined, so that the combination power can be obviously improved, and the operation stability of the electronic combination scale is higher.

The memory hopper 6 has no weighing function, and only the weighed weight of the upper weighing hopper 4 can be remembered (the data can be stored in the PLC after the weight of the upper weighing hopper 4 is weighed), so that the electronic combined weighing of the memory hopper 6 is suitable for non-sticky materials, the non-sticky materials can fall into the memory hopper 6 after passing through the discharge hopper 5, and no weight error exists; and some materials having viscosity such as hot pickled mustard tuber may be stuck on the sub hopper 5 after passing through the sub hopper 5, causing weight error, so in this case, it is preferable to adopt a lower weighing hopper under the sub hopper 5, the lower weighing hopper having a weighing function, and the lower weighing hopper can be precisely combined after being weighed.

In order to push out the materials in the discharge chute 2, a screw rod for conveying the materials into the buffer storage hopper 3 is arranged in the discharge chute 2. Through the rotation of hob, the material can be pushed into the buffer hopper 3.

Of course, the discharge chute 2 may be connected to a vibrator for driving the discharge chute 2 to vibrate. Through the transmission of vibrator, the spout 2 vibration also can be transferred the material to the outside.

The mechanism that opens and shuts is prior art, and the mechanism that opens and shuts all is equipped with weighing sensor in the last weighing fill 4 by PLC control, and weighing sensor is connected with PLC. The upper weighing hopper 4 stores data after weighing, and controls the opening and closing mechanism to be opened or closed.

Of course, in the case of adopting the lower weighing hopper, the lower weighing hopper is also internally provided with a weighing sensor, and the cover weighing sensor is also connected with the PLC.

Finally, it is worth mentioning that, as shown in fig. 4, the distributing hopper 5 of the present invention is hinged on the support 51, and the inner side of the distributing hopper 5 is connected with the distributing power source through the transmission link 52. The distributing power source drives the transmission connecting rod 52 to drive the distributing hopper 5 to rotate, so that the distributing hopper 5 can have the two states described above.
