Description

Technical Field

[0001] The utility model relates to the technical field of bean food processing, in particular to an automatic feeding device for bean food processing. Background Art

[0002] Soybeans must be soaked before tofu processing to soften their structure, reduce energy consumption and wear during refining, and improve the dispersion of soy protein colloids, thereby facilitating protein extraction and increasing protein extraction rate. Soaking also removes some anti-nutritional factors in the soybeans, such as phytic acid, tannins, and protease inhibitors, which can affect nutrient absorption. Soaking also partially softens the soybean skins, improving cooking and flavor.

[0003] When soaking, soybeans are usually poured into a container and an appropriate proportion of water is added to the container to completely submerge the soybeans to achieve the purpose of soaking. Existing factories usually put water and soybeans of approximately the same weight or volume into containers of the same specifications when processing tofu, so as to facilitate processing. However, when adding soybeans, the existing method is manual pouring, which not only consumes a lot of physical strength, but also requires adding water during the pouring process of the soybeans. It is not only troublesome, but also difficult to control the approximate capacity of the soybeans in the container, which may cause too many soybeans in the container, and the water overflows due to the expansion of the soybeans during the soaking process. Utility Model Content

[0004] Therefore, in order to solve the above-mentioned shortcomings, the present invention provides an automatic loading device for processing soy foods, which is used for automatic loading of soybeans, so that the soybeans can be poured into a container for soaking. The lifting conveyor, control system and motion mechanism in the automatic loading device can control the amount of soybeans discharged according to the level of soaking water in the container for soaking the soybeans, so as to automatically stop when the material is full and automatically discharge when there is no material, thereby avoiding excessive discharge of soybeans and causing water overflow in the container.

[0005] The present invention is achieved by constructing an automatic feeding device for processing soy food, comprising a lifting feeder and a control system, wherein the discharge pipe of the lifting feeder is arranged below the top, the control system controls the operation or stop of the lifting feeder, and a motion mechanism is movably installed at the end of the discharge pipe of the lifting feeder, the motion mechanism is electrically connected to the control system, when the motion mechanism moves to the lowest end under the action of gravity, the control system controls the lifting feeder to operate, and when the motion mechanism moves to the highest end under the support force of the bottom material, the control system controls the lifting feeder to stop.

[0006] In order to realize the lifting and conveying of soybeans and reduce the labor intensity of manual dumping of soybeans, a feasible solution is provided herein. Specifically, the lifting feeder includes a feed pipe inclined on the frame and a rotatable spiral shaft arranged inside the feed pipe. A feed hopper is arranged above the bottom end of the feed pipe, and a discharge pipe is arranged below the top end of the feed pipe. The control system includes a controller and a control motor. The control motor drives the spiral shaft to rotate, and the controller drives the control motor to run or stop. By setting an inclined feed pipe and an internal rotatable spiral shaft, combined with the feed hopper at the lower end of the feed pipe and the discharge pipe at the high end, the soybeans can be lifted and conveyed conveniently, and the soybeans can be dropped into the external soaking container. At the same time, the controller and the control motor are provided to realize the automatic rotation and stopping of the spiral shaft, which facilitates automatic unloading.

[0007] In order to realize the movement of the motion mechanism, thereby facilitating the subsequent automatic unloading of soybeans and avoiding overflow caused by excessive soybeans in the container and the continued unloading of the lifting conveyor, a feasible solution is provided herein. Specifically, the motion mechanism includes a fixed tube and a moving part. Connecting plates are respectively provided at both ends of the fixed tube. The fixed tube is connected to the end of the discharge pipe through the connecting plate on the top. The moving part is sleeved on the outer end of the fixed tube and passes through the connecting plate at the bottom to maintain up and down movement. Several guide columns installed on the outer end of the fixed tube are provided between the two connecting plates. By providing connecting plates at both ends of the fixed tube, it is convenient to maintain connection with the discharge pipe. The connection method can be a flange connection or a threaded connection, which also facilitates the installation of the moving part and realizes the movement of the moving part.

[0008] In order to realize the up and down movement of the movable part at the outer end of the fixed tube, thereby facilitating the subsequent automatic unloading of soybeans and avoiding overflow caused by excessive soybeans in the container and the lifting conveyor continuing to unload, a feasible solution is provided herein. Specifically, the movable part includes a movable ring and a buoyancy ring connected by a connecting column. The movable ring is sleeved on the outer end of the fixed tube and moves up and down along the fixed tube through the guide column. The connecting column passes through the connecting plate at the bottom end of the fixed tube and a buoyancy ring is arranged at the end. The inner diameter of the buoyancy ring is larger than the inner diameter of the fixed tube, and a chamfered corner is arranged on the buoyancy ring. By arranging the movable ring to be sleeved on the outer end of the fixed tube, it is convenient to move up and down along the fixed tube. At the same time, by setting the inner diameter of the buoyancy ring, it is prevented that the soybeans will not contact the buoyancy ring when falling from the fixed tube, affecting the rise of the buoyancy ring.

[0009] In order to enable the moving mechanism to move upward under the support of the material, and thus facilitate automatic dropping and stopping, a feasible solution is provided herein. Specifically, the buoyancy ring is made of a buoyant material, so that the buoyancy ring floats on the liquid surface. By setting the buoyancy ring to be made of a buoyant material, it is ensured that the water level rises when the soybeans fall into the soaking container, thereby pushing the entire moving part to rise under the action of buoyancy, thereby facilitating automatic dropping and stopping.

[0010] In order to ensure that the start and stop of the lifting conveyor is controlled when the moving part rises and falls, a feasible solution is provided here. Specifically, touch switches are provided at the bottom and top of the moving ring, and the touch switches are electrically connected to the control system. When the moving part slides down to the lowest end under the action of gravity, the touch switch at the bottom of the moving ring contacts the connecting plate at the bottom of the fixed tube, and a signal is sent to the control system through the touch switch to control the start of the lifting feeder. When the moving part moves up to the highest end under the supporting force of the bottom material, the touch switch at the top of the moving ring contacts the connecting plate at the top of the fixed tube, and the touch switch contacts the connecting plate at the top of the fixed tube. The switch sends a signal to the control system to control the lifting feeder to stop. By setting the touch switches at the bottom and top of the moving ring, the moving ring can move downward under gravity, and the touch switch at the bottom contacts the connecting disk at the outer end of the fixed tube, thereby sending a signal to the control system to control the operation of the lifting conveyor. At the same time, the moving parts move upward to the top under the support of the bottom material or the buoyancy of the water. After the touch switch at the top of the moving ring contacts the connecting disk, a signal is sent to the control system to control the lifting conveyor to stop, thereby realizing the feeding control process of the lifting conveyor automatically stopping when it is full and automatically dropping when there is no material.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] First of all, the automatic loading device can facilitate the lifting and transportation of soybeans by setting up a lifting conveyor, a control system and a motion mechanism, and then facilitate the pouring of soybeans into the soaking container, saving manpower labor, and the automatic start and stop of the lifting conveyor can be achieved through the movement of the motion mechanism and the control system, thereby realizing the function of automatically stopping the lifting conveyor when it is full of material during the loading process and automatically feeding when there is no material.

[0013] Secondly, the automatic feeding device, by setting the specific structure and connection form of the fixed tube and the moving part in the motion mechanism, can push the moving part upward after the soybeans fall into the container, and stop the operation of the lifting conveyor after the touch switch on the top of the moving part contacts the top, thereby realizing automatic stopping when the material is full. At the same time, after replacing the container, the moving part moves downward under gravity after losing the support of the material, and the lifting conveyor can be started after the touch switch at the bottom contacts the bottom, thereby realizing automatic feeding without material.

[0014] Finally, the automatic loading device is made of buoyancy material by setting the buoyancy ring, and the inner diameter of the buoyancy ring is larger than the inner diameter of the fixed tube, to ensure that when the soybeans fall into the soaking container for soaking, the water level in the soaking container rises, pushing the buoyancy ring and the moving ring to rise, realizing the upward movement process of the entire moving part, and avoiding the moving part being unable to rise and causing the lifting conveyor to be unable to stop automatically, affecting automatic loading.

It should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention in any way.

[0023] As described in the background art, during the tofu processing process, soybeans need to be poured into the soaking container manually for soaking, which is labor-intensive. In addition, if there are too many soybeans in the soaking container during the pouring process, the soaking water may overflow after swelling.

[0024] For the reasons mentioned above, please refer to the attached Figure 1 ~Attached Figure 2The utility model provides an automatic feeding device for processing bean-based food, including a lifting feeder and a control system. The discharge pipe 4 of the lifting feeder is arranged below the top, and the control system controls the operation or stop of the lifting feeder. A motion mechanism is movably installed at the end of the discharge pipe 4 of the lifting feeder. The motion mechanism is electrically connected to the control system. When the motion mechanism moves to the lowest end under the action of gravity, the control system controls the lifting feeder to operate. When the motion mechanism moves to the highest end under the supporting force of the bottom material, the control system controls the lifting feeder to stop.

[0025] In order to realize the lifting and conveying of soybeans and reduce the labor intensity of manual dumping of soybeans, a feasible solution is provided herein. Specifically, the lifting feeder includes a feeding pipe 2 inclined on the frame 1 and a rotatable spiral shaft arranged inside the feeding pipe 2. A feed hopper 3 is arranged above the bottom end of the feeding pipe 2, and a discharge pipe 4 is arranged below the top end of the feeding pipe 2. The control system includes a controller and a control motor. The control motor drives the spiral shaft to rotate, and the controller drives the control motor to run or stop. By setting an inclined feeding pipe and an internal rotatable spiral shaft, combined with the feed hopper at the lower end of the feeding pipe and the discharge pipe at the high end, the soybeans can be lifted and conveyed conveniently, and the soybeans can be conveniently dropped into the external soaking container. At the same time, the controller and the control motor are provided to realize the automatic rotation and stopping of the spiral shaft, which facilitates automatic unloading.

[0026] Furthermore, the control system can adopt an existing conventional PLC automatic control system, whose controller is a conventional MCU, and the control motor is a conventional three-phase asynchronous motor, which can be automatically controlled by the PLC automatic control system, and the lifting conveyor has an existing conventional spiral lifting feeder.

[0027] In order to realize the movement of the motion mechanism, so as to facilitate the subsequent automatic unloading of soybeans and avoid overflow caused by excessive soybeans in the container and continuous unloading of the lifting conveyor, a feasible solution is provided here. Please refer to the attached Figure 3 and attached Figure 4 Specifically, the motion mechanism includes a fixed tube 5 and a moving part, and connecting plates 6 are respectively provided at both ends of the fixed tube 5. The fixed tube 5 is connected to the end of the discharge tube 4 through the connecting plate 6 on the top. The moving part is sleeved on the outer end of the fixed tube 5 and passes through the connecting plate 6 at the bottom to maintain up and down movement. Several guide columns 7 installed on the outer end of the fixed tube 5 are provided between the two connecting plates 6. By providing connecting plates at both ends of the fixed tube, it is convenient to maintain connection with the discharge tube. The connection method can be a flange connection or a threaded connection (that is, an external thread is provided at the end of the discharge tube and an internal thread is provided at the inner end of the fixed tube). It is also convenient to install the moving part and realize the movement of the moving part.

[0028] In order to realize the up and down movement of the movable part at the outer end of the fixed tube, thereby facilitating the subsequent automatic unloading of soybeans and avoiding overflow caused by excessive soybeans in the container and the lifting conveyor continuing to unload, a feasible solution is provided herein. Specifically, the movable part includes a movable ring 8 and a buoyancy ring 10 connected by a connecting column 9. The movable ring 8 is sleeved on the outer end of the fixed tube 5 and passes through the guide column 7 to move up and down along the fixed tube 5. The connecting column 9 passes through the connecting plate 6 at the bottom end of the fixed tube 5 and a buoyancy ring 10 is arranged at the end. The inner diameter of the buoyancy ring 10 is larger than the inner diameter of the fixed tube 5, and a chamfered corner is arranged on the buoyancy ring 10. By arranging the movable ring to be sleeved on the outer end of the fixed tube, it is convenient to move up and down along the fixed tube. At the same time, by setting the inner diameter of the buoyancy ring, it is prevented that the soybeans will not contact the buoyancy ring when falling from the fixed tube, affecting the rise of the buoyancy ring.

[0029] In order to enable the moving mechanism to move upward under the support of the material, and thus facilitate automatic dropping and stopping, a feasible solution is provided herein. Specifically, the buoyancy ring 10 is made of a buoyant material, so that the buoyancy ring 10 floats on the liquid surface. By setting the buoyancy ring to be made of a buoyant material, it is ensured that the water level rises when the soybeans fall into the soaking container, thereby pushing the entire moving part to rise under the action of buoyancy, thereby facilitating automatic dropping and stopping.

[0030] In order to ensure that the start and stop of the lifting conveyor is controlled when the moving part rises and falls, a feasible solution is provided here. Specifically, a touch switch 11 is provided at the bottom and top of the moving ring 8. The touch switch 11 is electrically connected to the control system. When the moving part slides to the lowest end under the action of gravity, the touch switch 11 at the bottom of the moving ring 8 contacts the connecting plate 6 at the bottom of the fixed tube 5, and a signal is sent to the control system through the touch switch 11 to control the start of the lifting feeder (see the attached figure). Figure 3 ), when the moving part moves up to the highest end under the support force of the bottom material, the touch switch 11 on the top of the moving ring 8 contacts the connecting plate 6 on the top of the fixed tube 8, and the touch switch 11 sends a signal to the control system to control the lifting feeder to stop (see the attached Figure 4 ), by setting touch switches at the bottom and top of the moving ring, when the moving ring moves downward under gravity, the touch switch at the bottom contacts the connecting disk at the outer end of the fixed tube, thereby sending a signal to the control system to control the operation of the lifting conveyor. At the same time, the moving part moves upward to the top under the support of the bottom material or the buoyancy of the water. After the touch switch at the top of the moving ring contacts the connecting disk, a signal is sent to the control system to control the lifting conveyor to stop, thereby realizing the feeding control process of the lifting conveyor automatically stopping when the material is full and automatically dropping when there is no material.

[0031] Furthermore, casters are provided at the bottom of the frame 1 to facilitate the movement of the entire loading device and to adjust the position to correspond to the soaking container.

[0032] During the loading process, the automatic loading device places the soaking container on an external liftable trolley in advance, then moves it to the bottom of the discharge pipe 4, puts a preset proportion of water into the soaking container, and then starts the control system. The touch switch 11 at the bottom of the movable ring 8 contacts the connecting plate 6 under the fixed pipe 5, and sends a signal to the control system to control the motor to drive the spiral shaft in the feeding pipe 2 to rotate, thereby lifting the soybeans in the feed hopper 3 upward inside the feeding pipe 2 until they are discharged from the discharge pipe 4 and the fixed pipe 5 into the soaking container. When the soybeans in the soaking container reach a certain amount, the water level inside will rise, thereby pushing the buoyancy ring 10 and the movable ring 8 to rise, until When the touch switch 11 on the top of the moving ring 8 contacts the connecting plate 6 on the top of the fixed tube 5, a signal is sent to the control system to control the motor to stop running, indicating that the material is full and the loading needs to be stopped. Finally, the cart outside the immersion container is lowered and moved out, and another container is placed for replacement and loading. In the process of replacing the container, the moving ring 8 is bound to fall under the action of gravity, thereby squeezing the touch switch at the bottom. At this time, the staff should turn off the control system before replacing the container to avoid this situation causing incorrect loading, or according to the control logic of the control system, the moving ring should send a signal to the control system after it is lowered for the second time to control the operation of the lifting feeder to avoid incorrect loading.

[0033] The above description is a detailed description of the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modifications completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
