Description

A stirring device with auxiliary structure Technical Field

[0001] This utility model belongs to the field of ink production and processing technology, and more specifically, it relates to a stirring device with an auxiliary structure. Background Technology

[0002] In the ink production and processing industry, ink mixing is a crucial process, its core being the thorough blending of various ink raw materials into a uniform ink using mixing equipment. For the mixing of solvent-based high-gloss vinyl inks, given the high volatility of this type of ink, existing mixing equipment generally employs a sealed structure design. First, a hydraulic system drives the stirring blades and the sealing cap to move synchronously above the mixing tank. After the sealing cap and mixing tank are completely sealed, the drive mechanism then agitates the stirring blades to mix the solvent-based high-gloss vinyl ink within the tank. This ensures uniform ink mixing while effectively suppressing the safety hazards and quality impacts caused by solvent evaporation.

[0003] This utility model, with application number CN201720310293.2, relates to the technical field of ink processing equipment, specifically an ink mixing device. It includes a beam frame, a mixing device, and a housing. The mixing device comprises a beam frame and a housing, with the beam frame mounted above the housing. The beam frame and housing are connected by a hydraulic lifting rod, and a hydraulic drive box is located at the bottom of the hydraulic lifting rod. A control panel is located on the front end of the housing, and a power distribution junction box is located at the rear end of the beam frame. This utility model has a reasonable structure, is easy to use, and improves the efficiency of ink mixing. The sealed structure prevents dust diffusion during mixing, reducing splashing and contamination of the environment and ink loss. An auxiliary feeding observation hole allows for the addition of auxiliary materials and observation of the internal mixing process.

[0004] Based on the above, existing mixing equipment generally adopts a sealed structure design to mix solvent-based high-gloss vinyl inks. The sealing cover and the mixing shaft are mostly sealed by a sealing bushing. However, after long-term use, the sealing bushing is prone to aging or deformation due to increased pressure inside the sealed tank, affecting the sealing effect of the sealing bushing. This may cause volatile gases to leak into the external environment, posing a safety hazard. Moreover, the mixing shaft is also prone to displacement after long-term use. The displaced mixing shaft will vibrate during mixing operations due to uneven force, which not only affects the mixing effect but may also further aggravate the wear and leakage risk of the sealing bushing. Summary of the Invention

[0005] To address the aforementioned technical problems, this utility model provides a stirring device with an auxiliary structure. This addresses the common practice in existing stirring devices of using a sealed structure design for mixing solvent-based high-gloss vinyl inks. The sealing cap and stirring shaft are mostly sealed via a sealing bushing. However, after prolonged use, the sealing bushing is prone to aging or deformation due to increased pressure within the sealed container, affecting its sealing effect and potentially causing volatile gases to leak into the external environment, posing a safety hazard. Furthermore, the stirring shaft is also prone to displacement after prolonged use. A displaced stirring shaft will vibrate during stirring operations due to uneven force, not only affecting the stirring effect but also potentially exacerbating the wear and leakage risk of the sealing bushing.

[0006] The purpose and effect of this utility model of a stirring device with an auxiliary structure are achieved by the following specific technical means:

[0007] A mixing device with auxiliary structures includes a mixing body, a control mechanism, a hydraulic lifting rod, a crossbeam frame, a drive mechanism, a mixing tank, a sealing cover, a mixing shaft, a leak-proof component, and an offset component. The control mechanism is fixedly installed on one side of the mixing body; the hydraulic lifting rod is fixedly installed on the upper part of the mixing body; the crossbeam frame is fixedly installed on the top of the hydraulic lifting rod; the drive mechanism is fixedly installed on the upper part of the crossbeam frame; the mixing tank is installed inside the mixing body; the sealing cover is snapped onto the bottom of the crossbeam frame; the mixing shaft is rotatably connected inside the crossbeam frame and is installed at the bottom of the drive mechanism; the leak-proof component is located on the outside of the mixing shaft; and the offset component is located on the outside of the mixing shaft.

[0008] Furthermore, the leak-proof assembly includes: a sealing bushing and a second bushing, wherein the sealing bushing is fixedly installed on the top of the sealing cover; and the second bushing is fixedly installed on the upper part of the sealing bushing.

[0009] Furthermore, the leak-proof component also includes: a sealing ring and a through hole, the sealing ring being fixedly installed at the bottom of the second bushing, the sealing ring being located at the middle position between the sealing bushing and the second bushing; the through hole being circumferentially arranged at the bottom of the second bushing.

[0010] Furthermore, the leak-proof assembly also includes a sealing ring and a first elastic element, wherein the sealing ring is vertically slidably connected inside the second bushing; one end of the first elastic element is fixedly installed on the top of the inner side of the second bushing, and the other end of the first elastic element is fixedly installed on the top of the sealing ring.

[0011] Furthermore, the leak-proof assembly also includes: a first displacement sensor, one end of which is fixedly installed on the top of the inner side of the second bushing, and the other end of which is fixedly installed on the top of the sealing ring.

[0012] Furthermore, the offset component includes: a support frame and a transmission rod, wherein multiple sets of support frames are arranged in a circumferential array on the top of the second bushing; and multiple sets of transmission rods are arranged, wherein the multiple sets of transmission rods are slidably connected inside the multiple sets of support frames.

[0013] Furthermore, the offset assembly also includes: an arc-shaped plate, a second elastic element, and auxiliary rollers. Multiple sets of arc-shaped plates are provided, and the multiple sets of arc-shaped plates are respectively fixedly installed on the top of multiple sets of transmission rods. Multiple sets of second elastic elements are provided, with one end of the multiple sets of second elastic elements fixedly installed on the inner side of the multiple sets of arc-shaped plates, and the other end of the multiple sets of second elastic elements fixedly installed on one side of the multiple sets of support frames. Multiple sets of auxiliary rollers are provided, and the multiple sets of auxiliary rollers are rotatably connected inside the multiple sets of arc-shaped plates.

[0014] Furthermore, the offset component also includes: a second displacement sensor, wherein multiple sets of the second displacement sensor are provided, the multiple sets of the second displacement sensor are fixedly installed inside the support frame, and the top ends of the multiple sets of the second displacement sensor are fixedly connected to the ends of multiple sets of transmission rods.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] First, this utility model has a leak-proof component. The sealing performance between the sealing cover and the stirring shaft is enhanced by the sealing bushing and the second bushing, which avoids the safety hazards caused by leakage of the sealing bushing during the stirring process. Moreover, when the sealing bushing fails due to aging or pressure deformation, the leaking gas triggers the movement of the sealing ring. The first displacement sensor promptly feeds back the leakage signal to the control mechanism, which not only provides an early warning, but the sealing ring can also form a temporary barrier to prevent gas leakage and greatly reduce safety hazards.

[0017] Secondly, this invention features an offset component that uses elastic bonding and displacement sensing technology to dynamically monitor the state of the stirring shaft. The arc-shaped plate, under the action of the second elastic element, tightly conforms to the stirring shaft, assisting the rollers in reducing frictional loss. When the stirring shaft shifts, the eccentric rotation compresses the arc-shaped plate, driving the transmission rod to trigger the second displacement sensor. The control mechanism then issues an early warning, allowing operators to intervene promptly and preventing uneven stirring and increased vibration due to shaft offset, thereby reducing additional wear on the sealing bushing.

[0018] This invention has advantages such as leakage detection, offset detection, and stable operation. Through the leak prevention component and the offset component, it can promptly detect and remind the sealing bushing of leakage and promptly warn of the offset of the stirring shaft. Together, they form an auxiliary structure to assist ink stirring, making ink stirring more efficient and safer. Attached Figure Description

[0027] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0028] Example 1:

[0029] As shown in Figures 1 to 6:

[0030] This utility model provides a mixing device with an auxiliary structure, including a mixing body 1, a control mechanism 2, a hydraulic lifting rod 3, a crossbeam frame 4, a drive mechanism 5, a mixing tank 6, a sealing cover 7, a mixing shaft 8, and a leak-proof component. The control mechanism 2 is fixedly installed on one side of the mixing body 1; the hydraulic lifting rod 3 is fixedly installed on the upper part of the mixing body 1; the crossbeam frame 4 is fixedly installed on the top of the hydraulic lifting rod 3; the drive mechanism 5 is fixedly installed on the upper part of the crossbeam frame 4; the mixing tank 6 is installed inside the mixing body 1; the sealing cover 7 is snapped into the bottom of the crossbeam frame 4; the mixing shaft 8 is rotatably connected inside the crossbeam frame 4 and is installed at the bottom of the drive mechanism 5; the leak-proof component is located on the outside of the mixing shaft 8.

[0031] The leak-proof assembly includes a sealing bushing 801 and a second bushing 9. The sealing bushing 801 is fixedly installed on the top of the sealing cover 7, and the second bushing 9 is fixedly installed on the upper part of the sealing bushing 801.

[0032] The leak-proof component also includes: a sealing ring 901 and a through hole 902. The sealing ring 901 is fixedly installed at the bottom of the second bushing 9 and is located between the sealing bushing 801 and the second bushing 9. The through hole 902 is arranged in a circumferential array at the bottom of the second bushing 9.

[0033] The leak-proof component also includes a sealing ring 903 and a first elastic element 904. The sealing ring 903 is vertically slidably connected inside the second bushing 9. One end of the first elastic element 904 is fixedly installed on the top of the inner side of the second bushing 9, and the other end of the first elastic element 904 is fixedly installed on the top of the sealing ring 903.

[0034] The leak-proof component also includes: a first displacement sensor 905, one end of which is fixedly installed on the top of the inner side of the second bushing 9, and the other end of which is fixedly installed on the top of the sealing ring 903.

[0035] The specific usage and function of this embodiment are as follows:

[0036] The control mechanism 2 controls the hydraulic lifting rod 3 to rise and fall, so that the crossbeam frame 4 drives the sealing cover 7 to be installed on the upper part of the mixing tank 6 for sealing. The drive mechanism 5 drives the stirring shaft 8 to stir and mix the ink raw materials inside the mixing tank 6. The sealing bushing 801 seals the sealing cover 7 and the stirring shaft 8 to prevent the leakage of volatile gases.

[0037] During the mixing process, if the gas pressure inside the mixing tank 6 rises due to increased temperature or ink evaporation, and the sealing sleeve 801 ages or deforms and fails, the leaked gas will first enter the second sleeve 9. The sealing ring 901 strengthens the sealing effect between the sealing sleeve 801 and the second sleeve 9, allowing the leaked gas to preferentially enter the interior of the second sleeve 9. When the gas enters the interior of the second sleeve 9 through the through hole 902 and accumulates to a certain pressure, the gas pressure will overcome the elastic force of the first elastic element 904 and push the sealing ring 903 upward. The displacement of the sealing ring 903 will trigger the first displacement sensor 905, which is linked with the control mechanism 2 to immediately send a warning signal to the personnel that the sealing sleeve 801 has failed and is leaking gas. At the same time, the sealing ring 903 remains in contact with the inner wall of the second sleeve 9 during its upward movement, forming a temporary seal to prevent the gas from being directly discharged into the external environment without treatment, thus providing a safe buffer time for equipment shutdown and maintenance.

[0038] In this implementation, the signal linkage and early warning functions between the first displacement sensor 905 and the control mechanism 2 are all based on existing mature industrial automation technologies, which will not be elaborated here.

[0039] Example 2:

[0040] Based on Embodiment 1, as shown in Figures 1 to 6, it further includes: an offset component, which is disposed on the outside of the stirring shaft 8.

[0041] The offset component includes a support frame 906 and a transmission rod 907. Multiple sets of support frames 906 are arranged in a circumferential array on the top of the second bushing 9. Multiple sets of transmission rods 907 are arranged in a slidably connected to the inside of the multiple sets of support frames 906.

[0042] The offset assembly further includes: an arc-shaped plate 908, a second elastic element 9071, and auxiliary rollers 9081. Multiple sets of arc-shaped plates 908 are provided, and the multiple sets of arc-shaped plates 908 are respectively fixedly installed on the top ends of multiple sets of transmission rods 907. Multiple sets of second elastic elements 9071 are provided, with one end of the multiple sets of second elastic elements 9071 fixedly installed on the inner side of the multiple sets of arc-shaped plates 908, and the other end of the multiple sets of second elastic elements 9071 fixedly installed on one side of the multiple sets of support frames 906. Multiple sets of auxiliary rollers 9081 are provided, and the multiple sets of auxiliary rollers 9081 are rotatably connected inside the multiple sets of arc-shaped plates 908.

[0043] The offset component also includes: a second displacement sensor 909, which is provided in multiple sets. The multiple sets of second displacement sensors 909 are fixedly installed inside the support frame 906, and the top ends of the multiple sets of second displacement sensors 909 are fixedly connected to the ends of multiple sets of transmission rods 907.

[0044] The specific usage and function of this embodiment are as follows:

[0045] Under the elastic action, the second elastic element 9071 keeps the multiple sets of arc plates 908 in close contact with the outer wall of the stirring shaft 8. The auxiliary rollers 9081 on the inner side of the arc plates 908 roll in contact with the stirring shaft 8. While ensuring real-time monitoring of the shaft position, the sliding friction is converted into rolling friction, which greatly reduces mechanical wear and avoids damage to the surface of the stirring shaft 8.

[0046] When the stirring shaft 8 shifts due to prolonged use, its eccentric rotation will periodically compress the circumferentially distributed arc-shaped plates 908. Under this force, the arc-shaped plates 908 move towards the support frame 906 via the transmission rod 907, triggering the second displacement sensor 909 installed within the support frame 906. The second displacement sensor 909 is linked in real-time with the control mechanism 2, immediately sending a warning signal of stirring shaft 8 shift to the operator. This facilitates timely shutdown for calibration or replacement of components, preventing problems such as uneven stirring force, increased vibration, and additional wear on the sealing bushing 801 caused by the shift of the stirring shaft 8.

[0047] In this implementation, the signal linkage and early warning functions between the second displacement sensor 909 and the control mechanism 2 are all based on existing mature industrial automation technologies, which will not be elaborated here.
