Description

Technical Field

[0001] The utility model relates to the technical field of feeding control devices, and more specifically, to an automatic feeding control device for magnetic material processing. Background Art

[0002] When processing and magnetizing magnetic materials (such as magnetic blocks), a vibrating bowl feeder is needed to supply raw materials in a predetermined form. The feeding port of the vibrating bowl feeder is connected to a feeder that supplies raw materials continuously. When there is too much raw material in the vibrating bowl feeder, it will affect the flow of raw materials in the vibrating bowl feeder. Therefore, it is necessary to turn off the feeder to stop feeding. When there is less raw material in the vibrating bowl feeder, it is necessary to turn on the feeder to continue feeding. The opening and closing of the feeder need to be manually operated by workers according to the amount of raw materials in the vibrating bowl feeder, which is very inconvenient and labor-consuming. Moreover, for manual control, when people are inattentive, it often causes problems such as untimely feeding or excessive shutdown feeding. In view of this, overcoming the above-mentioned defects of the existing technology is an urgent problem to be solved in this technical field. Content of the Utility Model

[0003] The utility model provides an automatic feeding control device for magnetic material processing, aiming to improve the problem that the opening and closing of the current feeder need to be manually operated by workers according to the amount of raw materials in the vibrating bowl feeder, which is very inconvenient and labor-consuming.

[0004] To achieve the above purpose, the utility model provides an automatic feeding control device for magnetic material processing, and the specific technical solution is as follows:

[0005] An automatic feeding control device for magnetic material processing includes an installation mechanism. The installation mechanism includes an installation frame, on which an installation rod is provided. A control mechanism is provided at the front end of the installation rod. The control mechanism includes an installation block, which is fixedly installed at the end of the installation rod. A laser sensor is fixed on the installation block. The laser sensor is signal-connected to the feeder and can control the feeder by receiving different signals. A connecting shaft is provided below the laser sensor, which is fixed at the end of the installation rod. A dial needle is rotatably installed on the connecting shaft. The upper side of the dial needle can block the laser signal emitted by the laser sensor, and the lower side of the dial needle extends into the vibrating bowl feeder. The materials in the vibrating bowl feeder can push the dial needle to rotate around the connecting shaft. The rotation of the dial needle enables it to approach or move away from the laser sensor, so that the laser sensor can receive different signals.

[0006] In one embodiment, the pusher pin includes a connecting head rotatably mounted on a connecting shaft. A first connecting arm is provided on the lower side of the connecting head, and an arc head is provided at the end of the first connecting arm. The material in the vibrating bowl can drive the arc head. A second connecting arm is provided on the upper side of the connecting head, and a shielding head is provided at the end of the second connecting arm. The shielding head can block the signal emitted by the laser sensor.

[0007] In one embodiment, the connecting head is rotatably mounted on the connecting shaft through a bearing, and the connecting head is disposed outside the mounting block.

[0008] In one embodiment, the length of the first connecting arm is greater than the length of the second connecting arm.

[0009] In one embodiment, the mounting rod is inserted into the mounting frame, and the mounting rod can slide back and forth on the mounting frame.

[0010] In one embodiment, a platform is provided on one side of the mounting rod, and the platform abuts against a locking bolt which is screwed to the top end of the mounting frame.

[0011] In one embodiment, a base is fixed to the lower end of the mounting frame.

[0012] The beneficial effects of this embodiment are as follows:

[0013] By providing a control mechanism, when there is less raw material in the vibrating bowl, the raw material will be laid flat in a single layer on the bottom surface of the vibrating bowl. At this time, the single-layer raw material drives the arc head, and thus the amplitude of the arc head driving the first connecting arm is relatively small, so that the rotation angle of the connecting head is small, and then the swing amplitude of the connecting head driving the second connecting arm is small, and thus the swing amplitude of the shielding head is small, and then the shielding head always blocks the signal emitted by the laser sensor. At this time, the feeder is in the working state, so the feeder will continuously supply raw materials to the vibrating bowl, and there is less raw material in the vibrating bowl. When there is more raw material in the vibrating bowl, the raw materials in the vibrating bowl will be stacked together to form at least two layers in height. At this time, the raw material on the top layer drives the arc head. Since the height of the raw material on the top layer increases, the amplitude of the push on the arc head increases, and then the shielding head moves away from the signal area emitted by the laser sensor, and then the shielding head cannot block the signal. At this time, the laser sensor transmits this state signal to the feeder, and the feeder stops working, and then the feeder no longer supplies raw materials to the vibrating bowl, realizing automatic control of the start and stop of the feeder according to the change of the raw material in the vibrating bowl, without manual operation, greatly improving the automation degree, saving manpower and effectively improving the work efficiency.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] The technical solutions provided by the embodiments of the present utility model will be introduced below in conjunction with the accompanying drawings.

[0027] Please refer to Figure 1 、 Figure 5 and Figure 7 In one embodiment of the present utility model, a feeding automatic control device for magnetic material processing is provided, which includes an installation mechanism 100. The installation mechanism 100 includes an installation frame 110. A base 111 is fixed to the lower end of the installation frame 110. The base 111 facilitates the placement and installation of the installation frame 110. An installation rod 120 is inserted into the upper end of the installation frame 110. The installation rod 120 can slide back and forth on the installation frame 110, thereby adjusting the length of the installation rod 120 extending out of the installation frame 110. Specifically, a platform 121 is provided on one side of the installation rod 120. The platform 121 abuts against a locking bolt 130. The locking bolt 130 is screwed to the top of the installation frame 110. After adjusting the length of the installation rod 120 extending out, rotate the locking bolt 130, and then the locking bolt 130 presses the installation rod 120 against the installation frame 110 to achieve the position adjustment of the installation rod 120. The control mechanism 200 is installed on the installation rod 120. Thus, according to the position of the vibrating bowl, the position of the control mechanism 200 relative to the vibrating bowl can be adjusted in real time, greatly improving the mobility and flexibility of the entire device.

[0028] Please refer to Figure 2 、 Figure 3 and Figure 4, a control mechanism 200 is provided at the front end of the installation rod 120. The control mechanism 200 includes an installation block 210. The installation block 210 is fixedly installed at the end of the installation rod 120. A laser sensor 220 (the laser sensor is a diffuse reflection laser sensor) is fixed on the installation block 210. A laser sensor is a sensor that uses a laser beam to measure distance, detect objects, obtain the position of objects, or perform other tasks. They are based on the characteristics of the laser beam and can usually provide high-precision and non-contact control, suitable for various application fields. The laser sensor 220 is signal-connected to the feeder. The laser sensor 220 can control the feeder by receiving different signals. A connecting shaft 230 is provided on the lower side of the laser sensor 220. The connecting shaft 230 is fixed at the end of the installation rod 120 and passes through the installation block 210 and extends to the outside. A dialing needle 240 is rotatably installed on the connecting shaft 230 through a bearing. The upper side of the dialing needle 240 can block the laser signal emitted by the laser sensor 220. The lower side of the dialing needle 240 extends into the vibrating bowl. The material in the vibrating bowl can push the dialing needle 240 to rotate around the connecting shaft 230. The rotation of the dialing needle 240 enables it to approach or move away from the laser sensor 220, so that the laser sensor 220 can receive different signals;

[0029] Please refer to Figure 3 , Figure 4 and Figure 5 , it should be noted that the dialing needle 240 includes a connecting head 241. The connecting head 241 is rotatably installed on the connecting shaft 230 through a bearing. A first connecting arm 242 is provided on the lower side of the connecting head 241. An arc head 243 is provided at the end of the first connecting arm 242. The extension direction of the arc head 243 is the same as the raw material flow direction in the vibrating bowl. When the raw material in the vibrating bowl flows, it can push the arc head 243 forward. A second connecting arm 244 is provided on the upper side of the connecting head 241. The length of the first connecting arm 242 is greater than the length of the second connecting arm 244. A shielding head 245 is provided at the end of the second connecting arm 244. The shielding head 245 can block the signal emitted by the laser sensor 220.

[0030] The specific working process is as follows. The raw material in the vibrating bowl flows forward under the vibration of the vibrating bowl. When the raw material in the vibrating bowl is less, the raw material will be laid flat in a single layer on the bottom surface of the vibrating bowl. At this time, the single-layer raw material drives the arc head 243. Then, the driving amplitude of the arc head 243 on the first connecting arm 242 is relatively small, so that the rotation angle of the connecting head 241 is small. Then, the connecting head 241 drives the second connecting arm 244 to swing with a small amplitude, so that the shielding head 245 swings with a small amplitude. Then, the shielding head 245 always blocks the signal emitted by the laser sensor 220. At this time, the feeder is in the working state, so the feeder will continuously supply raw materials to the vibrating bowl;

[0031] When there is too much raw material in the vibrating bowl, the raw materials in the vibrating bowl will stack together, forming at least two layers in height. At this time, the raw materials on the top layer drive the arc head 243. Since the height of the raw materials on the top layer increases, the amplitude of the push on the arc head 243 increases accordingly. As a result, the amplitude of the drive of the first connecting arm 242 by the arc head 243 is relatively large, so that the connecting head 241 rotates by a relatively large angle. Then, the connecting head 241 drives the second connecting arm 244 to swing with a relatively large amplitude, and thus the shielding head 245 swings with a relatively large amplitude. Further, the shielding head 245 moves away from the signal area emitted by the laser sensor 220, and then the shielding head 245 cannot block the signal. At this time, the laser sensor 220 transmits this status signal to the feeder, and the feeder stops working. Further, the feeder no longer supplies materials to the vibrating bowl, realizing the automatic control of the start and stop of the feeder according to the change of the raw materials in the vibrating bowl, without manual operation, greatly improving the automation degree, saving manpower and effectively improving the work efficiency.

[0032] It should be noted that: the motion states, motion trajectories, etc. of each mechanism of this device can be automatically controlled through numerical control programs or PLC programming, etc., and cooperate with position switches, etc. to realize automatic start and stop and automatic operation. The above programs and programming are common knowledge for those skilled in the art, so they will not be described in detail here;

[0033] The specific model specifications of the feeder and the laser sensor 220 need to be selected according to the actual specifications of this device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0034] The power supply and its principle of the feeder and the laser sensor 220 are clear to those skilled in the art and will not be described in detail here.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
