Description

Technical Field

[0001] This 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 production process of abrasive tools, the accuracy of the mixing ratio of abrasives and adhesives has a great impact on the performance of abrasive tools. For the convenience of mixing and subsequent hot pressing forming, a high-temperature thermosetting adhesive is used. This adhesive is in a granular state at room temperature and is convenient for mixing with abrasives. For example, brown fused alumina is used as the abrasive in ordinary grinding wheels, and resin adhesive is used as the adhesive.

[0003] A mixing and stirring device for grinding wheel raw materials with the authorization announcement number of CN218530717U can realize the automatic mixing of abrasives and adhesives. The device includes a mixing tank. The output shaft of the second motor is fixedly connected with a screw rod through a coupling. A material distribution frame is welded and fixed on the surface of the rotating rod. Through the setting of the second motor and the material distribution frame, through the cooperation of the second motor, the screw rod and the mixing tank, the abrasives and adhesives can be premixed. Through the cooperation of the material distribution frame, through holes, the first motor, the rotating rod and the first stirring rod, the abrasives and adhesives can be secondarily mixed by the first stirring rod. Through the setting of the auger blades, before the abrasives and adhesives after secondary mixing fall to the bottom of the mixing tank for stirring and mixing, they can be tertiary mixed by the auger blades.

[0004] However, in the actual application process, the storage process of resin adhesives will be affected by the external temperature and humidity, causing some resin adhesive particles to stick to each other. Even if the resin adhesive is stored in a sealed manner, under the action of the day-night temperature difference, it will cause the resin molecular chain to repeatedly expand and contract thermally, promoting the molecular diffusion and penetration of the particle contact surface, and then causing adjacent resin adhesive particles to stick.

[0005] After the resin adhesive particles stick together, the particle size of the adhesive raw material becomes inconsistent and the difference is too large. After feeding into the above patent, the mixing of the adhesive and the abrasive will be very uneven, thereby affecting the performance of the subsequent abrasive tool products.

Specific embodiments

[0032] The adhesive and abrasive mixing device and mixing method of the present application will be further described in detail with reference to the accompanying drawings, but it is not a limitation to the present application.

[0033] As shown in Figure 1 Figure 1, an adhesive and abrasive mixing device includes a feeding assembly and a mixing assembly.

[0034] As shown in Figures 2 to 4 Figure 2, the feeding assembly includes at least two bins 1. One of the bins 1 is used to store adhesive raw materials, and the other bins are used to store abrasive raw materials. The blanking pipe 101 vertically arranged at the bottom of the bin 1 is connected to the mixing assembly through the discharge pipe 4, and the discharge pipe 4 is horizontally arranged.

[0035] Inside the discharge pipe 4 corresponding to the bin 1 filled with adhesive, there is a powdering device 6, which is used to crush the passing adhesive.

[0036] One end of the discharge pipe 4 is connected to the mixing tank 8 in the mixing assembly in a through manner, and the other end is provided with an air inlet pipe 401.

[0037] As shown in Figure 5 Figure 3, the powdering device 6 includes a first rotating shaft 601 coaxially arranged and rotatably connected to the discharge pipe 4. On the first rotating shaft 601, there are coaxially arranged an impeller 602 and at least two groups of blade sets 603. Each group of blade sets 603 contains several blades distributed in an annular array around the axis of the first rotating shaft 601. At both ends of the first rotating shaft 601, there are respectively clamped with rotatably connected rotating sleeves 604. Outside the rotating sleeves 604, there is a coaxially arranged fixing ring 605 fixedly connected through a connecting rod. The fixing ring 605 is fixedly connected to the discharge pipe 4.

[0038] The fixing ring 605 and the discharge pipe 4 can be fixedly connected by cold pressing fit or interference fit. It is also possible to recess threaded holes on the outer circumferential surface of the fixing ring 605, provide through holes at the corresponding positions on the circumferential surface of the discharge pipe 4, and then fix the fixing ring 605 through screws passing through the through holes.

[0039] A quantitative feeder 7 is provided between the blanking pipe 101 and the discharge pipe 4. As shown in Figure 6 Figure 4, the quantitative feeder 7 includes a first motor 701. The output end of the first motor 701 is connected to a second rotating shaft 702. On the second rotating shaft 702, there are spaced apart a lower isolation plate 703 and an upper isolation plate 704. The lower isolation plate 703 is provided with lower through holes 7031, and the upper isolation plate 704 is provided with upper through holes 7041. The lower through holes 7031 and the upper through holes 7041 are arranged staggeredly.

[0040] Below the vertically arranged blanking pipe 101, there are spaced apart intermediate material pipes 2. Below the intermediate material pipes 2, there are spaced apart end material pipes 3. The end material pipes 3 are connected to the discharge pipe 4 in a through manner. The blanking pipe 101, the intermediate material pipes 2, and the end material pipes 3 are fixedly connected through a connecting frame 5.

[0041] The upper isolation plate 704 is inserted between the blanking pipe 101 and the intermediate material pipe 2, and the lower isolation plate 703 is inserted between the intermediate material pipe 2 and the end material pipe 3.

[0042] The inner diameter of the intermediate material pipe 2 is greater than or equal to the inner diameters of the blanking pipe 101 and the end material pipe 3, and the inner diameters of the lower through hole 7031 and the upper through hole 7041 are the same as the inner diameter of the intermediate material pipe 2.

[0043] In this embodiment, the center of the lower through hole 7031 is spaced 180° from the center of the upper through hole 7041. In this way, when the upper through hole 7041 rotates to between the blanking pipe 101 and the intermediate material pipe 2, the intermediate material pipe 2 and the end material pipe 3 are isolated by the lower isolation plate 703, realizing the feeding into the intermediate material pipe 2. The feeding amount is determined by the volume of the intermediate material pipe 2, thereby realizing the ratio of the adhesive to the abrasive. A vibrator can be added outside the intermediate material pipe 2 to fill its interior by vibration.

[0044] 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 coaxially arranged 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 and cannot feed.

[0045] Existing metering feeders, such as the sealed metering feeder of Changtai Electromechanical Equipment Co., Ltd., include a conveying module, a weighing and metering module, and a metering control module. Its working principle is to transmit the load and speed signals of the conveying belt to a measurement control instrument or an industrial control computer. The instrument or the industrial control computer performs internal operations 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 conveying belt to make the feeding amount as close as possible to or equal to the set feeding amount.

[0046] Compared with the metering feeder in the above-mentioned prior art, the metering feeder 7 in this embodiment reduces the weighing and metering module and the metering control module. The conveying module also omits the conveying belt and only relies on three sections of pipelines to complete the transfer of materials by the self-weight of the materials, with a simple and efficient structure and low cost. By controlling the start and stop of the first motor 701, metering feeding can be completed, and the operation is more efficient.

[0047] As shown by Figures 7 to 10 The mixing assembly includes a mixing tank 8. The end of the discharge pipe 4 is connected to the mixing tank 8 in a penetrating manner. A stirring device is provided inside the mixing tank 8, and a discharging assembly is provided below the mixing tank 8. An inlet 801 is provided at the upper part of the circumferential surface of the mixing tank 8, and the discharge pipe 4 is connected to the inlet 801 in a penetrating manner.

[0048] As shown by Figure 12As shown, the stirring device includes a third rotating shaft 14, a stirrer 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.

[0049] The stirrer 15 includes a fourth rotating shaft 1501, and a plurality of stirring blades 1502 are fixed on the fourth rotating shaft 1501 and distributed in an annular array around its axis. One end of the fourth rotating shaft 1501 is rotatably connected to the third rotating shaft 14, and a gear 1503 is fixed at the other end.

[0050] A ring gear 13 is coaxially fixed on the inner wall of the mixing tank 8, and the gear 1503 is placed on the ring gear 13, and the gear 1503 is meshed and connected with the ring gear 13.

[0051] During the process that the second motor 16 drives the third rotating shaft 14 to rotate, the third rotating shaft 14 drives the stirrer 15 to rotate around its axis. During the rotation of the stirrer 15, since the gear 1503 is meshed and connected with the ring gear 13 and the ring gear 13 is fixed, the gear 1503 rotates, and then drives the stirring blades 1502 to rotate through the fourth rotating shaft 1501, which plays a role in stirring the materials inside the mixing tank 8 in multiple directions, thereby optimizing the mixing effect of the binder and the abrasive.

[0052] 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 in its axial cross-section. On one side of the axis, there are successively a supporting inclined surface 802 and a material guiding inclined surface 803 arranged obliquely. The included angle between the supporting inclined surface 802 and the material guiding inclined surface 803 is 90°, and they are transitioned by an arc. The end of the material guiding inclined surface 803 abuts against the circumferential surface perpendicular to the mixing tank 8.

[0053] The ring gear 13 is arranged on the material guiding inclined surface 803, and the end surface of the stirring blade 1502 abuts against the supporting inclined surface 802 and the position below the ring gear 13 on the material guiding inclined surface 803. This arrangement can realize stirring the materials by rotating along the third rotating shaft 14, self-rotating along the fourth rotating shaft 1501, and at the same time, the materials will also move from the center of the mixing tank 8 to the outside for mixing. The materials achieve at least three-directional movement, further optimizing the mixing uniformity of the binder and the abrasive.

[0054] A plurality of air outlets 804 are provided on the top surface of the mixing tank 8. A wind guiding cover 18 is provided at the top of the mixing tank 8. The wind guiding cover 18 with an open upper end is frustum-shaped, and the second motor 16 and the air outlets 804 are both arranged inside the wind guiding cover 18. In this way, the high-pressure air for feeding can be further utilized, and its discharge path can be planned. Through the wind guiding cover 18, forced air cooling is carried out on the second motor 16. A filter plate 19 is provided on the air outlet 804.

[0055] In this embodiment, the discharging assembly includes at least two valve plates 9. The valve plates 9 are arranged at the junction of the supporting inclined surface 802 and the material guiding inclined surface 803. When the valve plates 9 are closed, their top surfaces are flush with the bottom surface of the mixing tank 8 and have the same shape. A control plate 901 is provided on the outer side of the bottom of the valve plate 9, and rotating rods protrude from both ends of the control plate 901.

[0056] A receiving bin 17 is sleeved on the outer bottom of the mixing tank 8. The receiving bin 17 is funnel-shaped, and a discharging pipe 1701 is provided at the lower position of the bottom of the receiving bin 17.

[0057] A bracket 10 is fixed to the inner wall of the receiving bin 17. Two brackets 10 form a group to clamp the control plate 901. A vertical waist-shaped hole 1001 is provided on the bracket 10, and the rotating rod at the end of the control plate 901 is slidably arranged inside the vertical waist-shaped hole 1001.

[0058] A top rod 11 arranged vertically is provided at the bottom of the control plate 901. The bottom of the top rod 11 is connected with a telescopic device 12, and the telescopic device 12 can adopt an electric telescopic rod or a pneumatic telescopic rod. When the top rod 11 moves up to the highest point, the valve plate 9 is pushed onto the mixing tank 8 to seal the discharging port of the mixing tank 8. When the top rod 11 moves down, the valve plate 9 moves down accordingly and rotates around the rotating rod of the control plate 901 to increase the opening angle.

[0059] A mixing method of an adhesive and an abrasive, based on the above-mentioned adhesive and abrasive mixing device, includes the following steps: S01. Put the adhesive into the bin 1 connected to the powder material device 6, put the abrasive into the remaining bins 1, and connect each air inlet pipe 401 to the external high-pressure gas supply system; Feed materials into the discharging pipe 4 in proportion through the quantitative feeder 7. After the feeding is completed, inject high-pressure gas into the discharging pipe 4, and the high-pressure gas drives the materials into the mixing tank 8; S02. While the high-pressure gas in the adhesive discharging pipe 4 blows the adhesive, it also blows the impeller 602, and then drives the blade group 603 to rotate through the first rotating shaft 601. The rotating blade group 603 impacts and cuts the passing adhesive to separate the adhesive particles stuck together; S03. The adhesive and the abrasive entering the inside of the mixing tank 8 are stirred and mixed by the stirring device, and after mixing, they are discharged through the opened discharging assembly.
