Referring to fig. 1 to 3, an automatic batching device in one embodiment includes a controller 1 and a plurality of spiral feeders 2, which can save batching time and improve component ratio accuracy of raw materials.

Specifically, the spiral feeder 2 includes a base 21 and a body 23. The base 21 is provided with a load cell 22. The body 23 is supported and mounted on the base 21 by the load cell 22. The housing 21 is used to mount and support the housing and the components, and its structure is set as required. The load cell 22 supports the body 23 and weighs the body 23. The load cell 22 may be selected from a cantilever type, bridge type, etc.

The body 23 is provided with a stepping motor 232 and a material conveying pipe 231 arranged transversely. Both ends of the feed delivery pipe 231 are closed. A storage hopper 233 is arranged above one end of the delivery pipe 231, and the storage hopper 233 is communicated with the delivery pipe 231. The storage hopper 233 is disposed on the body 23. In one embodiment, the storage hopper 233 is rigidly connected to the delivery conduit 231. The other end of the delivery pipe 231 is provided with a feeding port 2311. A spiral pushing rod 234 is arranged in the material conveying pipe 231, and the stepping motor 232 is used for driving the spiral pushing rod 234 to rotate. The storage hopper 233 is used for holding raw materials to be used. The stepper motor 232 drives the screw pushing rod 234 to rotate to push the material to be fed to the feeding port 2311. The raw material is discharged through a feed inlet 2311 for dosing. The load cell 22 weighs the body 23 and the raw material contained in the body 23.

The feeding port 2311 is provided with a sliding baffle 235 and an electrically controlled telescopic driver 236. The sliding shutter 235 is slidably disposed on the body 23. One end of the electrically controlled telescopic driver 236 is disposed on the body 23, and the other end of the electrically controlled telescopic driver 236 is connected to the sliding baffle 235. The electric control telescopic driver 236 can control the sliding baffle 235 to slide, so that the sliding baffle 235 closes or partially closes the feeding port 2311. Specifically, the opposite sides of the feeding port 2311 are respectively provided with a sliding chute. The sliding baffle 235 is slidably disposed in the sliding groove at both sides thereof. One end of the electrically controlled telescopic driver 236 close to the sliding baffle 235 is limited on the sliding baffle 235. The sliding baffle 235 controls the opening size of the feeding port 2311 in a sliding mode. Thereby adjusting the rate at which raw material is discharged from the feed opening 2311. When the discharge speed of raw materials is lower, the discharge amount of the raw materials can be accurately controlled, so that the proportion accuracy of each component of the raw materials is improved, and the performance of the produced finished product is more stable. When the discharge speed of the raw materials is higher, the batching time can be reduced.

In one embodiment, the electrically controlled telescopic driver 236 is an electrically driven telescopic rod. It is understood that the electrically controlled telescopic driver 236 may also be a linear motor, an electrically controlled hydraulic cylinder, or other telescopic driving components capable of controlling the telescopic length.

The controller 1 is electrically connected to each load cell 22, the stepping motor 232, and the electrically controlled telescopic driver 236. The controller 1 controls the rotation speed of the stepping motor 232 and the electronically controlled telescopic driver 236 to extend and contract according to the measured weight signal of the load cell 22. During material mixing, the controller 1 respectively controls the spiral batch feeders 2 to feed materials simultaneously according to the received material mixing demands. The load cell 22 continuously transmits a measuring signal to the controller 1, and the difference between the two measured values before and after the load cell 22 is the weight of the raw material fed by the screw feeder 2 in the period. Specifically, the controller 1 controls the rotation speed of the stepping motor 232 to adjust the feeding speed of the screw pushing rod 234. The controller 1 controls the electrically controlled telescopic driver 236 to adjust the opening size of the feeding port 2311. When the controller 1 receives that the difference between the weight signal of the weighing sensor 22 and the target value of the batching demand is large, the feeding speed is increased, the opening size of the feeding port 2311 is increased, and the feeding speed is increased; when the controller 1 receives that the weight signal of the weighing sensor 22 is close to the target value of the batching demand, the feeding speed is reduced, and the opening size of the feeding port 2311 is reduced, so that the feeding precision can be controlled more accurately; the controller 1 controls each spiral feeder 2 at the same time, thereby saving the batching time and improving the component proportion accuracy of the raw materials.

It can be understood that the rotation speed control of the stepping motor 232, the signal collection of the weighing sensor 22, and the extension and retraction control of the linear motor, the electrically controlled hydraulic cylinder or the electric telescopic rod belong to the common technologies, and the specific control principle is not described herein. The control of the stepping motor 232 and the electrically controlled telescopic driver 236 by the signal of the load cell 22 can be realized by a PLC program or an industrial personal computer.

An elastic supporting mechanism 238 is vertically arranged in the recovery bucket 237, and a bottom sealing plate 239 is arranged at the lower part of the elastic supporting mechanism 238. The resilient support 238 provides a resilient force to close the bottom closure plate 239 to the bottom opening of the recycling bin 237. When the feeding speed exceeds the discharging speed of the feeding port 2311, the raw materials overcome the elasticity of the elastic supporting mechanism 238 under the thrust action of the spiral pushing rod 234, and the bottom sealing plate 239 is opened to enter the recovery hopper 237, so that the raw materials are prevented from being compressed due to overlarge stress, the discharging of the feeding port 2311 is prevented from being influenced, and the feeding precision is ensured. Specifically, the elastic support mechanism 238 further includes a support bar 2381 and a support spring 2382. A support bar 2381 is slidably disposed within the retrieval bin 237. The lower end of the support bar 2381 extends to the bottom of the recovery bucket 237 and is connected with the bottom sealing plate 239. One end of the support spring 2382 is connected to the support rod 2381, and the other end of the support spring 2382 is connected to the recovery bucket 237. The support spring 2382 provides an elastic force to slide the support rod 2381 toward the bottom of the collection bucket 237, and the bottom seal plate 239 abuts against the edge of the opening of the bottom of the collection bucket 237. In one embodiment, the collection bucket 237 is provided with a mounting portion 2371. The upper end of the support bar 2381 is slidably inserted into the mounting portion 2371. The middle part of the support bar 2381 is screwed with a support block 2383. The supporting spring 2382 is sleeved outside the supporting rod 2381, the upper end of the supporting spring 2382 is abutted to the mounting portion 2371, and the lower end of the supporting spring 2382 is abutted to the supporting block 2383. The opening pressure of the bottom sealing plate 239 can be adjusted by adjusting the position of the support block 2383 screwed on the support bar 2381, so that the bottom sealing plate is suitable for different types of raw materials. In one embodiment, the mounting portion 2371 is a beam disposed at the top of the retrieval bucket 237 and within the retrieval bucket 237.

According to the automatic batching device in the technical scheme, the storage hoppers 233 of the spiral batch feeders 2 respectively store various raw materials; during material distribution, the controller 1 controls the spiral material feeders 2 to feed materials simultaneously, and the controller 1 controls the corresponding stepping motors 232 and the electric control telescopic drivers 236 respectively according to the weight signals of the weighing sensors 22 to adjust the feeding speed of the spiral material pushing rods 234 and the opening size of the material inlet 2311, so that the material distribution time is saved, and the component proportion accuracy of raw materials is improved.
