Description

Technical Field

[0001] This utility model relates to the field of stirring technology, and in particular to an auxiliary positioning device for stirring in a mixing tank. Background Technology

[0002] Mixing tanks are widely used for mixing chemical products such as coatings, inks, pigments, and adhesives. Currently, mixing tanks need to be moved directly under the mixing shaft of a lifting mixing device. After being manually positioned, the tank is secured using a clamping device to prevent movement during mixing. This current method is cumbersome, time-consuming, and labor-intensive, requiring manual adjustment of the tank's position and operation of the clamping device.

[0003] Based on this, this application provides an auxiliary positioning device that can quickly position and fix the mixing tank to solve the above problems. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art. Therefore, the present invention provides an auxiliary positioning device for stirring a mixing tank, achieving the purpose of quickly positioning and fixing the mixing tank.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An auxiliary positioning device for stirring a mixing tank is provided, comprising an electromagnet located directly below the stirring shaft of the stirring device, an elastic magnetic chuck located at the center of the bottom of the mixing tank, guide rails located on the left and right sides of the electromagnet, and a limiting rod located behind the electromagnet for limiting the elastic magnetic chuck; directional casters and swivel casters are fixedly installed on the front and rear sides of the mixing tank via support seats, and the two guide rails are used for guiding and limiting the mixing tank in the left and right directions; the elastic magnetic chuck includes a fixed cylinder, a magnetic chuck that moves through the fixed cylinder, and a return spring located between the bottom of the fixed cylinder and the top flange plate of the magnetic chuck, and the fixed cylinder is fixedly installed on the bottom of the tank.

[0007] In some alternative embodiments, both the electromagnet and the limiting rod are fixedly mounted on a fixed base anchored to the ground, wherein the limiting rod is horizontally mounted to the fixed base via a bracket.

[0008] In some optional embodiments, a proximity switch and a PLC controller are also included. The proximity switch is located inside the limit rod and is used to detect the position of the elastic magnetic attractor of the mixing tank. The PLC controller is electrically connected to the proximity switch and the electromagnet.

[0009] In some alternative implementations, an unlocking switch is also included, which is electrically connected to the PLC controller.

[0010] In some alternative embodiments, the guide rail has a flared guide groove at its entry end.

[0011] In some alternative embodiments, the magnetic body is provided with a weight-reducing hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses guide rails and limiting rods to limit the left and right directions and the entry depth of the mixing tank, respectively, to ensure that the mixing tank is located directly below the mixing shaft. When the electromagnet is energized, it can attract the magnetic body of the elastic magnetic body to fix the mixing tank. After the mixing is completed, the electromagnet is de-energized and the elastic magnetic body is reset. At this time, the mixing tank can be moved, thereby achieving rapid positioning and fixing of the mixing tank.

[0014] 2. The proximity switch and PLC controller are configured such that the proximity switch sends a signal to the PLC controller, which then controls the electromagnet to be energized to fix the mixing tank. This achieves automatic fixing of the mixing tank after it is pushed into place. After mixing is completed, the unlocking switch sends an unlocking signal, which in turn controls the electromagnet to be de-energized by the PLC controller, thus enabling the mixing tank to be unlocked quickly.

[0026] Example 1

[0027] As attached Figure 1As shown, this embodiment provides an auxiliary positioning device for stirring a mixing tank, including an electromagnet 1, an elastic magnetic accumulator 2, a guide rail 3, a limit rod 4, a proximity switch 5, a PLC controller 6, and an unlocking switch 7, wherein:

[0028] The electromagnet 1 is located directly below the stirring shaft 10.1 of the stirring device 10, and is fixedly mounted on the fixed base 8 anchored to the ground.

[0029] The elastic magnetic chuck 2 is located at the center of the bottom of the mixing tank 20. Preferably, as shown in the attached diagram... Figure 2 As shown, the elastic magnetic chuck 2 in this embodiment includes a fixed cylinder 2.1, a magnetic chuck 2.2, and a return spring 2.3. The top flange of the fixed cylinder 2.1 is fixedly installed at the bottom of the mixing tank 20. The magnetic chuck 2.2 movably passes through the fixed cylinder 2.1 and can move up and down within the fixed cylinder (the magnetic chuck is generally made of iron). The return spring 2.3 is located between the bottom of the fixed cylinder and the top flange of the magnetic chuck 2.2. Preferably, the magnetic chuck 2.2 in this embodiment has a weight-reducing hole 2.2.0 inside, which can reduce the weight of the magnetic chuck and also reduce manufacturing costs.

[0030] Two guide rails 3 are respectively located on the left and right sides of the electromagnet 1, and are arranged symmetrically in mirror image with the stirring device as the central axis. They are fixedly installed on the ground and are used to guide and limit the left and right movement of the casters of the stirring tank. Preferably, in this embodiment, directional casters 20.1 and swivel casters 20.2 are fixedly installed on the front and rear sides of the stirring tank 20 via support seats. The directional casters and swivel casters have the same wheel width. The inner width of the guide rail 3 is slightly larger than the wheel width of the directional casters and swivel casters, and its height is sufficient to avoid interference with the directional casters and swivel casters. Preferably, as shown in the attached... Figure 3 As shown, in this embodiment, a trumpet-shaped guide groove 3.1 is provided at the entry end of the guide rail 3 to facilitate guiding the mixing tank into the guide rail. The guide rail in this embodiment limits the left and right positions of the mixing tank.

[0031] The limiting rod 4 is located behind the electromagnet 1, specifically mounted laterally to the fixed base 8 via a bracket, and is used to limit the elastic magnetic chuck 2, that is, to limit the pushing depth of the mixing tank 20. Therefore, the limiting rod in this embodiment achieves the limitation of the movement position of the mixing tank toward the stirring device. The installation position of the limiting rod in this embodiment should meet the following requirement: when the fixed cylinder of the elastic magnetic chuck contacts the limiting rod, the mixing tank is exactly located directly below the stirring shaft.

[0032] To achieve automatic fixation of the mixing tank using an electromagnet after it reaches its designated position, as shown in the attached document... Figure 1 and attached Figure 2As shown, this embodiment further includes a proximity switch 5 and a PLC controller 6. The proximity switch 5 is located inside the limit rod 4 and is used to detect the position of the elastic magnetic attractor of the mixing tank. The PLC controller 6 is electrically connected to the proximity switch 5 and the electromagnet 1. Specifically, the proximity switch is connected to the signal input terminal of the PLC controller; the positive terminal of the electromagnet's power supply is connected to one output port of the PLC controller, and the negative terminal of the electromagnet's power supply is connected to the negative terminal of the power supply.

[0033] Working principle: When the proximity switch detects the elastic magnetic body, it means that the mixing tank is directly below the stirring shaft. At this time, the proximity switch feeds back the signal to the PLC controller, which then turns on the power to the electromagnet. The electromagnet then becomes magnetic, generating a magnetic attraction effect, and attracts the magnetic body in the elastic magnetic body to fix the position of the mixing tank.

[0034] Furthermore, to quickly release the mixing tank, this embodiment also includes an unlocking switch 7, preferably a foot-operated unlocking switch, which can be placed near the mixing tank for easy operation. Specifically, the unlocking switch 7 in this embodiment is electrically connected to the signal input terminal of the PLC controller 6. When it is necessary to unlock the mixing tank, the unlocking switch is pressed. After receiving the unlocking signal, the PLC controller controls the electromagnet to de-energize. At this time, the electromagnet is demagnetized, and the magnetic attractor is reset under the action of the return spring, thus unlocking the mixing tank.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
