Description

Technical Field

[0001] The present application belongs to the technical field of material mixing, and specifically relates to an adhesive and abrasive mixing device and a mixing method. Background Art

[0002] During the abrasive tool production process, the precise mixing ratio of abrasive to binder significantly impacts tool performance. To facilitate mixing and subsequent hot pressing, a high-temperature thermosetting binder is used. This binder is granular at room temperature, making it easier to mix with the abrasive. For example, conventional grinding wheels use brown corundum as the abrasive and a resin as the binder.

[0003] Authorization announcement number CN218530717U discloses a grinding wheel raw material mixing and stirring device that can automatically mix abrasive and adhesive. The device includes a mixing box, the output shaft of a second motor fixedly connected to a spiral rod via a coupling, and a distribution frame welded to the surface of the rotating rod. The second motor and the distribution frame, along with the second motor, spiral rod, and mixing tank, allow for pre-mixing of the abrasive and adhesive. The distribution frame, through-holes, first motor, rotating rod, and first stirring rod cooperate to achieve secondary mixing of the abrasive and adhesive via the first stirring rod. The auger blades ensure that the secondary mixed abrasive and adhesive are mixed a third time before falling to the bottom of the mixing box for mixing.

[0004] However, in actual use, the storage process of resin adhesives is affected by external temperature and humidity, causing some resin adhesive particles to stick together. Even if the resin adhesive is stored in a sealed manner, the temperature difference between day and night will cause the resin molecular chains to repeatedly expand and contract, promoting molecular diffusion and penetration at the contact surface of the particles, and thus causing adjacent resin adhesive particles to stick together.

[0005] After the resin adhesive particles stick together, the particle size of the adhesive raw material is not uniform and the difference is too large. After the above patent is added, the adhesive and abrasive are mixed very unevenly, which in turn affects the performance of the subsequent abrasive products. Summary of the Invention

[0006] The technical problem to be solved by the present application is: to overcome the shortcomings of the existing technology and provide an adhesive and abrasive mixing device and a mixing method. Before the adhesive and abrasive are mixed, the particles that adhere to each other will be broken up by a rotating blade group to ensure the consistency of the adhesive particle size during mixing, thereby optimizing the mixing effect with the abrasive and ensuring the performance of the grinding tool.

[0018] Preferably, the mixing assembly includes a mixing tank, the end of the discharge pipe is connected to the mixing tank, a stirring device is provided inside the mixing tank, and a discharge assembly is provided below the mixing tank.

[0019] Preferably, the stirring device comprises a third rotating shaft, a stirrer and a second motor. The second motor is arranged above the outside of the mixing tank, and the third rotating shaft is connected to the second motor.

[0020] The stirrer comprises a fourth rotating shaft, on which a plurality of stirring blades distributed in a ring array around the axis are fixed. One end of the fourth rotating shaft is rotatably connected to the third rotating shaft, and the other end is fixed with a gear.

At the same time, under the guidance of the supporting inclined surface, the abrasive and adhesive inside the mixing tank can be displaced in at least three directions, thereby optimizing the stirring and mixing effect and ensuring the consistency of the mixing ratio of the abrasive and adhesive.

DETAILED DESCRIPTION

[0046] The adhesive and abrasive mixing device and mixing method of the present application are further described in detail with reference to the accompanying drawings, but are not intended to limit the present application.

[0047] Depend on Figure 1 As shown, a device for mixing adhesive and abrasive includes a feeding assembly and a mixing assembly.

[0048] Depend on Figures 2 to 4 As shown, the feed assembly includes at least two silos 1, one of which is used to store adhesive raw materials and the other is used to store abrasive raw materials. A vertically arranged feed pipe 101 at the bottom of the silo 1 is connected to the mixing assembly through a discharge pipe 4, which is arranged horizontally.

[0049] A powder device 6 is provided inside the discharge pipe 4 corresponding to the silo 1 filled with adhesive, and the powder device 6 is used to crush the adhesive passing through.

[0050] One end of the discharge pipe 4 is connected to the mixing tank 8 in the mixing assembly, and the other end is provided with an air inlet pipe 401.

[0051] Depend on Figure 5 As shown, the powder device 6 includes a first rotating shaft 601 coaxially arranged and rotatably connected to the discharge pipe 4. The first rotating shaft 601 is coaxially provided with an impeller 602 and at least two blade assemblies 603. Each blade assembly 603 includes a plurality of blades distributed in an annular array around the axis of the first rotating shaft 601. Rotating sleeves 604 are rotatably attached to each end of the first rotating shaft 601. A coaxially arranged fixing ring 605 is fixedly connected to the exterior of the rotating sleeve 604 via a connecting rod. The fixing ring 605 is fixedly connected to the discharge pipe 4.

[0052] The fixing ring 605 and the discharge pipe 4 can be fixedly connected by cold press fitting or interference fit, or a threaded hole can be recessed on the outer circumferential surface of the fixing ring 605, and a through hole can be provided at a relative position on the circumferential surface of the discharge pipe 4, and then the fixing ring 605 can be fixed by screws passing through the through hole.

[0053] A quantitative feeder 7 is provided between the feed pipe 101 and the discharge pipe 4. Figure 6 As shown, the quantitative feeder 7 includes a first motor 701, the output end of the first motor 701 is connected to the second rotating shaft 702, and the second rotating shaft 702 is provided with a lower isolation plate 703 and an upper isolation plate 704, the lower isolation plate 703 is provided with a lower through hole 7031, and the upper isolation plate 704 is provided with an upper through hole 7041, and the lower through hole 7031 and the upper through hole 7041 are arranged alternately.

[0054] An intermediate material pipe 2 is spaced below the vertically arranged feed pipe 101 , and an end material pipe 3 is spaced below the intermediate material pipe 2 . The end material pipe 3 is connected to the discharge pipe 4 . The feed pipe 101 , the intermediate material pipe 2 and the end material pipe 3 are fixedly connected by a connecting frame 5 .

[0055] The upper isolation plate 704 is inserted between the lower material pipe 101 and the middle material pipe 2 , and the lower isolation plate 703 is inserted between the middle material pipe 2 and the terminal material pipe 3 .

[0056] The inner diameter of the intermediate material pipe 2 is greater than or equal to the inner diameters of the lower material pipe 101 and the terminal material pipe 3 , and the inner diameters of the lower through hole 7031 and the upper through hole 7041 are equal to the inner diameter of the intermediate material pipe 2 .

[0057] In this embodiment, the center of the lower through hole 7031 is spaced 180° from the center of the upper through hole 7041. This allows for the lower through hole 7041 to be positioned between the lower feed pipe 101 and the intermediate feed pipe 2, separating the intermediate feed pipe 2 from the terminal feed pipe 3 by the lower isolation plate 703. This allows for feeding into the interior of the intermediate feed pipe 2. The volume of the intermediate feed pipe 2 determines the feed amount, thereby adjusting the ratio of adhesive to abrasive. A vibrator can be installed outside the intermediate feed pipe 2 to vibrate the interior to ensure it is filled.

[0058] When feeding is required, the first motor 701 is started, and the lower isolation plate 703 and the upper isolation plate 704 rotate synchronously. When the lower through hole 7031 moves to be coaxial with the intermediate material pipe 2, the upper isolation plate 704 blocks the upper port of the intermediate material pipe 2, and the intermediate material pipe 2 can only discharge materials but not feed materials.

[0059] Existing quantitative feeders, such as the sealed quantitative feeder of Changtai Mechanical and Electrical Equipment Co., Ltd., include a conveying module, a weighing and metering module, and a quantitative control module. Its working principle is to transmit the load and speed signals of the conveyor belt to the measuring and control instrument or industrial computer. The instrument or industrial computer performs internal calculations on the load and speed signals to calculate the actual feeding amount, and continuously compares the actual feeding amount with the set feeding amount, thereby controlling the speed of the conveyor belt to make the feeding amount as close to or equal to the set feeding amount as possible.

[0060] Compared to the conventional quantitative feeders, the quantitative feeder 7 of this embodiment eliminates the weighing and metering module and the quantitative control module. The conveying module also omits the conveyor belt, relying solely on the weight of the material through three sections of piping to transfer the material. This results in a simple, efficient, and low-cost structure. Quantitative feeding can be accomplished by controlling the start and stop of the first motor 701, making the operation more efficient.

[0061] Depend on Figures 7 to 10 As shown, the mixing assembly includes a mixing tank 8, the end of the discharge pipe 4 is connected to the mixing tank 8, a stirring device is provided inside the mixing tank 8, and a discharge assembly is provided below the mixing tank 8. A feed port 801 is provided on the upper circumference of the mixing tank 8, and the discharge pipe 4 is connected to the feed port 801.

[0062] Depend on Figure 12 As shown, the stirring device includes a third rotating shaft 14 , an agitator 15 and a second motor 16 ; the second motor 16 is arranged above the outside of the mixing tank 8 , and the third rotating shaft 14 is connected to the second motor 16 .

[0063] The stirrer 15 includes a fourth rotating shaft 1501 , on which are fixed a plurality of stirring blades 1502 distributed in a circular array around the axis thereof. One end of the fourth rotating shaft 1501 is rotatably connected to the third rotating shaft 14 , and a gear 1503 is fixed to the other end.

[0064] An annular gear ring 13 is coaxially fixed to the inner wall of the mixing tank 8 , and the gear 1503 is placed on the annular gear ring 13 , and the gear 1503 is meshed and connected with the annular gear ring 13 .

[0065] As the second motor 16 drives the third rotating shaft 14 to rotate, the third rotating shaft 14 drives the agitator 15 to rotate about its axis. During the rotation of the agitator 15, since the gear 1503 is meshed with the annular ring gear 13, the annular ring gear 13 remains stationary, while the gear 1503 rotates. This in turn drives the agitator blades 1502 to rotate via the fourth rotating shaft 1501, thereby achieving multi-directional agitation of the materials within the mixing tank 8, thereby optimizing the mixing effect of the adhesive and abrasive.

[0066] In order to reduce the stirring blind area at the bottom of the mixing tank 8 during stirring, in this embodiment, Figure 10 As shown, the bottom surface of the mixing tank 8 is similar to a W-shape along its axial cross-section, with an inclined supporting slope 802 and a material guiding slope 803 arranged on one side of the axis. The angle between the supporting slope 802 and the material guiding slope 803 is 90°. Through the arc transition, the end of the material guiding slope 803 abuts against the vertically arranged circumferential surface of the mixing tank 8.

[0067] The annular gear ring 13 is positioned on the material guide slope 803, and the end surface of the stirring blade 1502 abuts against the support slope 802 and the material guide slope 803 below the annular gear ring 13. This arrangement allows the material to be stirred by rotation along the third rotating axis 14 and by rotation along the fourth rotating axis 1501. Simultaneously, the material moves outward from the center of the mixing tank 8 to mix. This allows the material to move in at least three directions, further optimizing the uniformity of the adhesive and abrasive mixing.

[0068] The top surface of the mixing tank 8 is provided with a plurality of air outlets 804. A frustum-shaped air shroud 18 is provided on the top of the mixing tank 8. The air shroud 18, with its upper end open, is disposed within the frustum-shaped air shroud 18. The second motor 16 and the air outlets 804 are both located within the air shroud 18. This allows for further utilization of the high-pressure air being fed, directing its discharge path and providing forced cooling to the second motor 16 through the air shroud 18. A filter plate 19 is provided above the air outlet 804.

[0069] In this embodiment, the discharge assembly includes at least two valve plates 9, which are positioned at the intersection of the support slope 802 and the material guide slope 803. When the valve plates 9 are sealed, their top surfaces are flush with the bottom surface of the mixing tank 8, forming a consistent shape. A control plate 901 is located on the outside of the bottom of the valve plates 9, with rotating rods protruding from both ends of the control plates 901.

[0070] A material receiving bin 17 is sleeved on the bottom of the outer side of the mixing tank 8 . The material receiving bin 17 is funnel-shaped, and a discharge pipe 1701 is provided at the lower position of the bottom of the material receiving bin 17 .

[0071] The inner wall of the receiving bin 17 is fixed with a bracket 10, and two brackets 10 are a group to clamp the control board 901. The bracket 10 is provided with a vertical waist-shaped hole 1001, and the rotating rod at the end of the control board 901 is slidably arranged inside the vertical waist-shaped hole 1001.

[0072] A vertical push rod 11 is located at the bottom of the control panel 901. Connected to its base is a telescopic mechanism 12, which can be either electric or pneumatic. When push rod 11 reaches its highest point, it pushes valve plate 9 against mixing tank 8, sealing the discharge port. As push rod 11 descends, valve plate 9 also descends and rotates around the control panel 901's pivot rod, increasing the opening angle.

[0073] A method for mixing an adhesive and an abrasive, based on the above-mentioned adhesive and abrasive mixing device, comprises the following steps:

[0074] S01. Place the adhesive into the silo 1 connected to the powder device 6, place the abrasive into the remaining silos 1, and connect each air inlet pipe 401 to the external high-pressure air supply system;

[0075] The material is fed into the discharge pipe 4 in proportion by the quantitative feeder 7. After the feeding is completed, high-pressure gas is injected into the discharge pipe 4, and the high-pressure gas drives the material into the mixing tank 8;

[0076] S02. The high-pressure gas in the adhesive discharge pipe 4 blows the adhesive and also blows the impeller 602, which in turn drives the blade assembly 603 to rotate through the first rotating shaft 601. The rotating blade assembly 603 impacts and cuts the passing adhesive, separating the adhesive particles that are stuck together.

[0077] S03, the adhesive and the abrasive entering the mixing tank 8 are stirred and mixed by the stirring device, and then discharged through the opened discharge assembly.

[0078] The above describes the implementation methods of the present application in detail in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present application.
