Description

Technical Field

[0001] This invention belongs to the field of diamond wire manufacturing, and particularly relates to a multi-station mixing device for diamond abrasive. Background Technology

[0002] Diamond wire, also known as diamond cutting wire, is a novel cutting tool in which diamond powder is fixed to the surface of a metal busbar. Its core structure typically consists of a high-strength metal wire as the matrix and diamond powder attached to the busbar surface. The extremely high hardness of the diamond powder endows the diamond wire with excellent cutting performance, enabling efficient cutting of hard and brittle materials. In the industrial field, diamond wire has a wide range of applications, playing an irreplaceable role, especially in the processing of hard and brittle materials such as photovoltaic silicon wafers, sapphire, and ceramics. Compared with traditional cutting methods, diamond wire cutting offers significant advantages such as high cutting efficiency, low material loss, and good surface finish, greatly promoting technological progress and capacity expansion in related industries.

[0003] In the manufacturing process of diamond wire, the sand coating process is one of the most crucial steps. The core purpose of this process is to uniformly and firmly adhere diamond micropowder to the surface of the diamond wire, ensuring stable cutting performance. During the sand coating process, the diamond micropowder needs to be pretreated before use. One key step is mixing the diamond micropowder with relevant binders and additives in a specific ratio to form a mixture. Stirring is necessary to ensure that all components in the mixture are fully integrated and evenly distributed. Only a uniformly mixed diamond micropowder mixture can guarantee that the diamond micropowder adheres evenly to the surface of the wire during the subsequent sand coating process, thus ensuring product quality and cutting effect. If the mixture is not stirred evenly, the distribution of diamond micropowder on the wire will be uneven, leading to unstable cutting performance, affecting cutting accuracy and efficiency, and potentially causing wire breakage during cutting.

[0004] In current diamond abrasive mixture preparation processes, most mixing devices employ a single-station independent mixing method for mixing diamond micron powder mixtures. This method allows only one batch of mixture to be mixed at a time. When large quantities of mixture need to be prepared to meet diamond wire production demands, multiple repetitive mixing operations are required, a cumbersome process that severely restricts production efficiency and is difficult to adapt to the pace of large-scale industrial production. Furthermore, after mixing, operators must manually lift the mixing motor and paddle to remove the container and replace it with a new one each time the container is changed. Since the mixing motor and paddle themselves are heavy, manual lifting is not only labor-intensive and increases operator fatigue, but also poses safety hazards and prolongs container replacement time, further impacting overall production efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-station mixing device for corundum to solve the technical problems of low mixing efficiency and cumbersome operation of existing mixing equipment.

[0006] To achieve the above objectives, the specific technical solution of the multi-station mixing device for diamond abrasive of the present invention is as follows:

[0007] A multi-station mixing device for corundum includes a mixing frame, a lifting drive device disposed on the mixing frame, a lifting frame connected to the drive end of the lifting drive device, a plurality of mixing drive devices disposed on the lifting frame, and a mixing container disposed corresponding to the mixing drive devices.

[0008] The mixing container is located below the mixing drive device, and the mixing drive device extends a mixing shaft into the mixing container, and the mixing blades on the mixing shaft agitate the diamond abrasive mixture in the mixing container.

[0009] The stirring frame is provided with a mounting frame arranged parallel to the driving direction of the lifting drive device. The mounting frame is provided with a vertical guide rail, and a guide rail slider is slidably connected to the vertical guide rail. The guide rail slider is connected to the lifting frame. The driving end of the lifting drive device extends and retracts, causing the lifting frame to move up and down along the vertical guide rail, thereby causing the stirring shaft to move up and down relative to the stirring container.

[0010] As a further improvement of the present invention, the lifting frame includes a horizontal frame and a vertical frame. The horizontal frame is arranged parallel to the stirring frame above the stirring frame. The vertical frame protrudes upward from the upper end of the horizontal frame. The vertical frame has a hollow structure with an open lower end. The lifting drive device enters the hollow interior of the vertical frame from the lower end opening of the vertical frame. The driving end of the lifting drive device is connected to the upper end of the vertical frame.

[0011] As a further improvement of the present invention, the mounting bracket is vertically arranged on the upper end face of the stirring rack and symmetrically arranged on both sides of the vertical frame. The vertical guide rail is correspondingly arranged on the opposite outer side of the mounting bracket, and the guide rail slider is connected to the horizontal frame.

[0012] As a further improvement of the present invention, the horizontal frame is a rectangular frame, the stirring drive device is set at the four corners of the rectangular frame, two parallel connecting beams are set in the middle of the rectangular frame, and the vertical frame is set on the upper surface of the connecting beams.

[0013] As a further improvement of the present invention, the stirring rack is provided with a placement groove for placing the stirring container. The bottom surface of the placement groove is provided with a positioning protrusion, and the lower end surface of the stirring container is provided with a matching positioning groove corresponding to the positioning protrusion. The positioning groove fits onto the positioning protrusion to realize the placement and positioning of the stirring container in the placement groove.

[0014] As a further improvement of the present invention, the stirring drive device is a stirring motor, the stirring motor has a downward extending output shaft, and the output shaft is connected to the stirring shaft through a coupling.

[0015] As a further improvement of the present invention, an ultrasonic vibration device is provided at the bottom of the placement tank, and the vibration output end of the ultrasonic vibration device is in contact with the bottom of the placement tank to avoid the adhering of the diamond abrasive mixture in the mixing container.

[0016] As a further improvement of the present invention, the stirring drive device is provided with a corresponding stirring control device, which controls the stirring drive device.

[0017] As a further improvement of the present invention, the stirring container is equipped with a temperature sensor, a liquid level sensor and a concentration sensor, and the stirring control device displays the temperature, liquid level and concentration of the diamond abrasive mixture in the stirring container in real time based on the information fed back by the temperature sensor, the liquid level sensor and the concentration sensor.

[0018] As a further improvement of the present invention, the stirring shaft is a hollow structure with an open top and a closed bottom. A temperature regulating device is provided inside the hollow structure. The control end of the temperature regulating device is led out from the upper opening of the stirring shaft and connected to the stirring control device. The temperature regulating device is used to regulate the stirring temperature.

[0019] Beneficial effects:

[0020] The device of this application constructs a multi-station parallel operation mixing structure by setting several mixing drive devices on the lifting frame and correspondingly configuring mixing containers. It can simultaneously mix multiple portions of diamond abrasive mixture, significantly increasing the mixing volume per unit time, reducing batch waiting time, effectively adapting to the continuous supply demand of diamond abrasive mixture in large-scale production, and improving production efficiency by several times compared with traditional devices.

[0021] By utilizing the drive connection between the lifting drive device and the lifting frame, along with the sliding guide structure of the vertical guide rails and guide rail sliders on the mounting frame, stable lifting and lowering of the stirring shaft relative to the stirring container is achieved. When it is necessary to change the stirring container or adjust the stirring depth, there is no need to manually lift the stirring drive device and the stirring shaft; the operation can be completed simply by extending and retracting the lifting drive device. This significantly reduces the labor intensity of operators, minimizes auxiliary work time, and avoids potential safety hazards associated with manual operation, making equipment operation more convenient and safer.

[0022] The mounting bracket on the mixing frame is set parallel to the vertical guide rail and the lifting drive device. The rigid connection between the guide rail slider and the lifting frame forms a stable guiding support structure. When the lifting drive device moves the lifting frame, the vertical guide rail can strictly limit the movement trajectory of the lifting frame, ensuring that the mixing shaft always remains vertical. This avoids problems such as collision between the mixing paddle and the mixing container or uneven mixing caused by shaking during the mixing process, ensuring the stability and accuracy of the mixing operation, and helping to improve the mixing quality of the corundum mixture.

[0023] The multi-station design of the equipment allows for flexible adjustment of the number of stirring drive devices and stirring containers according to actual production needs. It can meet the stirring requirements of small-batch, multi-variety production as well as adapt to large-batch, continuous production scenarios. Furthermore, the height adjustment of the lifting frame allows for the adaptation to different specifications of stirring containers, improving the equipment's versatility and reducing the cost for companies to replace equipment due to changes in product specifications.

[0028] To better understand the purpose, structure, and function of this invention, the following detailed description of a multi-station abrasive mixing device is provided in conjunction with the accompanying drawings.

[0029] Implementation example:

[0030] like Figure 1-3 The diagram shows a multi-station abrasive mixing device. The mixing frame 1 is the basic support structure of the device, with an overall rectangular frame structure. It serves as the load-bearing foundation for the entire device and is used to install the lifting drive device 2, the mounting frame 11, and to place the mixing container 5. The lifting frame 3 is positioned above the mixing frame 1 via the lifting drive device 2 and the mounting frame 11, and also serves as the carrier for the mixing drive device 4, moving up and down relative to the mixing frame 1 under the drive of the lifting drive device 2.

[0031] The lifting frame 3 consists of a horizontal frame 31 and a vertical frame 32. The horizontal frame 31 is an "eye"-shaped frame with two parallel connecting beams welded in the middle. Four stirring drive devices 4 are installed at the four corners of the rectangle. The rectangular frame structure ensures the stability of multi-station stirring. The vertical frame 32 is a hollow frame with an open bottom. The bottom opening is "mouth"-shaped and fixed to the two connecting beams in the middle of the horizontal frame 31. Two columns stand on the connecting beams, and the top ends are connected by a top plate. The lifting drive device 2 enters the vertical frame 32 from the bottom opening along the vertical direction. The top end of the lifting drive device 2 extends out and connects to the top plate. The vertical frame 32 serves as the connecting carrier between the lifting drive device 2 and the horizontal frame 31, evenly transmitting the driving force to the horizontal frame 31 to achieve stable overall lifting. Mounting bracket 11 extends upwards from stirring bracket 1 through horizontal frame 31. Two vertically erected mounting brackets 11 are symmetrically arranged on both sides of vertical frame 32. Vertical guide rails 111 are arranged on the outer side of vertical frame 32, and guide rail sliders 112 are slidably mounted on vertical guide rails 111. The two guide rail sliders 112 are respectively connected to the two sides of horizontal frame 31. Mounting bracket 11 provides fixed support for guide rails; vertical guide rails 111 and guide rail sliders 112 form a guiding mechanism, restricting the movement trajectory of lifting frame 3, ensuring that horizontal frame 31 remains horizontal during lifting, avoiding equipment collision or uneven mixing caused by tilting of stirring shaft 41, and improving the operational stability of the device.

[0032] In this embodiment, the lifting drive device 2 is a cylinder structure, the drive end is a cylinder telescopic rod, the telescopic rod is fixed to the top of the lifting frame 3 through a bushing, and the bottom fixed end is bolted to the stirring frame 1 through a flange. Through the telescopic movement of the drive end, the lifting frame 3 is driven to move up and down in the vertical direction, so as to realize the relative position adjustment between the stirring shaft 41 and the stirring container 5, meet the needs of the stirring paddle to immerse / detach from the material, replace the traditional manual lifting operation, and reduce labor intensity.

[0033] In this embodiment, the stirring drive device 4 is a motor structure. The output speed is adjusted by a reducer. A mounting flange at the bottom of the motor is connected to preset holes at the four corners of a horizontal frame via bolts. The output shaft extends downwards and is connected to the stirring shaft 41 via a coupling. It provides power for the stirring operation, driving the stirring shaft 41 and the stirring paddle to rotate, thus agitating the diamond abrasive mixture and achieving uniform mixing. The reducer allows for flexible adjustment of the stirring speed according to the material characteristics, adapting to the stirring requirements of diamond abrasives of different particle sizes.

[0034] A placement groove 12 is provided on the mixing frame 1 directly below the stirring drive device 4. The stirring container 5 is placed in the placement groove 12. In this embodiment, the stirring container 5 is a circular bucket, and the placement groove 12 is a matching rectangle. The bottom of the placement groove 12 has a positioning protrusion protruding upwards, and the bottom of the bucket has a corresponding positioning groove. The bucket is positioned by matching the positioning groove with the positioning protrusion. The stirring container 5 serves as the carrier container for the diamond abrasive mixture. The precise fit between the positioning groove and the placement groove prevents the container from shifting during the stirring process. The anti-stick coating on the inner wall reduces material residue, improves stirring efficiency, and facilitates container cleaning. A set of ultrasonic vibration devices is installed at the bottom of each placement groove 12. The ultrasonic vibration devices are fixed in the placement groove 12 with bolts, and their vibration output end is tightly fitted with the support panel at the bottom of the placement groove 12 to ensure that the vibration energy can be effectively transmitted to the bucket. According to the characteristics of the diamond abrasive mixture, the vibration frequency of the ultrasonic vibration device is set to 20-40kHz. The high-frequency vibration generated by the ultrasonic vibration device can effectively break the agglomeration between diamond abrasive particles, making the diamond abrasive powder more evenly dispersed in the mixture.

[0035] Each stirring drive unit 4 is equipped with a corresponding stirring control unit 6, which is fixed on a horizontal frame next to the stirring drive unit. In this embodiment, the stirring control unit adopts a PLC control system, which allows parameter settings (stirring speed, stirring time) through a touch screen and knobs, and displays the equipment operating status in real time, enabling independent operation of multiple workstations and turning the stirring workstation on and off according to specific working conditions. The stirring shaft 41 has a hollow structure. In this embodiment, the temperature adjustment device is a heating rod, which is set inside the stirring shaft. The control end is led out from the opening at the upper end of the stirring shaft and connected to the stirring control unit to ensure the stirring temperature.

[0036] The mixing container 5 is equipped with a temperature sensor, a liquid level sensor, and a concentration sensor. The mixing control device, corresponding to these sensors, displays the temperature, liquid level, and concentration of the mixture in real time on a touchscreen. The liquid level sensor is installed in the upper-middle part of the inner wall of the mixing container, monitoring the liquid level in real time and displaying it on the mixing control device. When the material reaches the preset maximum liquid level, the sensor feeds a signal back to the control system, promptly reminding the operator to stop adding material to avoid spillage, waste, and equipment contamination. Conversely, when the liquid level falls below the preset minimum liquid level during mixing, a prompt is also issued, allowing the operator to replenish material promptly and ensuring continuous mixing operations. The temperature sensor is embedded in the inner wall of the mixing container, collecting real-time temperature data during mixing. If the temperature is too high, the control system can adjust the speed of the mixing motor to reduce the mixing intensity and minimize heat generation. If the temperature is too low, affecting the mixing effect, it provides temperature information to the heating device, ensuring that the material is mixed in a suitable temperature environment and guaranteeing mixing quality. The concentration sensor is installed near the bottom of the mixing container to monitor changes in the concentration or consistency of the material. During the mixing process of materials such as corundum, the uniformity of concentration directly affects the subsequent processing quality. Sensors can provide real-time feedback on material concentration information. When uneven concentration is detected, the control system can adjust the speed of the mixing motor or extend the mixing time, and even adjust the mixing depth of the mixing paddle in conjunction with the lifting frame to promote thorough mixing of materials and ensure the consistency of material concentration at each workstation.

[0037] In operation, the operator pours the diamond abrasive mixture into the mixing container 5, and places the container at the designated position by engaging the positioning protrusion in the placement slot with the positioning groove. The mixing parameters are set via the mixing control device 6, and the lifting drive device 2 is activated. The drive end extends, causing the lifting frame 3 to descend, immersing the mixing paddle into the material to the preset depth. After mixing is complete, the drive end of the lifting drive device 2 retracts, disengaging the mixing paddle from the material. The operator then removes the mixing container 5, completing one mixing operation.

[0038] The device described in this application significantly improves production efficiency through multi-station synchronous stirring, adapting to the needs of large-scale production; the automated lifting and adjustment and precise positioning design simplify the operation process and reduce labor intensity; the rigid guide structure ensures stable operation of the stirring shaft, and the flexible speed adjustment improves the uniformity and quality of stirring; the intelligent control facilitates parameter adjustment and status monitoring, making operation more convenient and precise.

Furthermore, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the invention.
