Description

Technical Field

[0001] This invention relates to the field of resin grinding wheel production technology, and in particular to a batching and mixing device for resin grinding wheel production. Background Technology

[0002] As is well known, resin grinding wheels are grinding wheels made of resin. They have high strength and are used in cutting discs, double-end grinding wheels, heavy-duty grinding wheels, polishing wheels, etc. They have certain elasticity, low heat resistance, good self-sharpening properties, are easy to manufacture, and have a short process cycle. They are widely used in rough grinding, rough grinding, cutting and free grinding, such as grinding steel ingots and deburring castings.

[0003] Currently, mixing devices are commonly used in the processing and production of resin grinding wheels. For example, the prior art CN212888345U discloses a raw material mixing device for resin grinding wheel production. This utility model increases the mixing force by having two internal mixing components and two external mixing components simultaneously perform reverse mixing, resulting in better mixing effect and more thorough mixing of raw materials.

[0004] However, in the process of mixing various ingredients required for the production of resin grinding wheels, the existing technology mainly uses agitators for rotary mixing. This makes it difficult to fully exchange and mix the raw materials in different locations, resulting in poor material uniformity. Often, it is necessary to increase the mixing time to achieve full mixing, which leads to poor overall mixing efficiency and effect. Summary of the Invention

[0005] Based on the technical problems existing in the background art, the present invention proposes a batching and mixing device for the production of resin grinding wheels.

[0006] The present invention proposes a batching and mixing device for resin grinding wheel production, including a U-shaped base, a swing mechanism provided on the inner side of the U-shaped base, and a device shell movably installed inside the U-shaped base through the swing mechanism. A mixing inner cylinder for mixing the batching materials used in resin grinding wheel production is also movably installed in the vertical direction inside the device shell.

[0007] A lifting plate is movably installed inside the outer shell of the device located below the mixing inner cylinder. The top two sides of the lifting plate are also fixedly connected to the bottom side of the mixing inner cylinder through support frames. A dual-shaft extension motor is fixedly installed at the bottom center of the mixing inner cylinder. The upper output shaft of the dual-shaft extension motor rotates through the mixing inner cylinder and is fixedly connected to a stirring shaft. Spiral mixing blades are also fixedly installed on the stirring shaft.

[0008] The lower output shaft of the dual-shaft extension motor rotates through to the bottom of the lifting plate and is fixedly connected to a worm gear; vertical frames are fixedly installed on the inner walls of the bottom side of the device housing on both sides of the worm gear, and rotating seats are slidably installed in the vertical direction in both vertical frames, and the same rotating shaft is rotatably installed on the two rotating seats. A worm wheel is fixedly sleeved in the middle of the rotating shaft, and the worm gear meshes with the worm wheel; cams are fixedly sleeved at both ends of the rotating shaft, and the top and bottom of the cams are respectively rolledly connected to the bottom side of the lifting plate and the inner wall of the bottom side of the device housing.

[0009] Furthermore, vertical grooves are provided on the rear inner walls of both vertical frames, and vertical sliders are fixedly connected to the rear sides of both rotating seats. The vertical sliders are slidably installed in the vertical grooves in the vertical direction. A return spring is also fixedly connected between the vertical sliders and the bottom inner walls of the vertical grooves.

[0010] Furthermore, the spiral mixing direction of the spiral mixing blade is specifically set to spiral output from bottom to top; both sides of the spiral mixing blade are fixedly connected with mixing rods arranged in upper and lower layers.

[0011] Furthermore, the bottom side of the lifting plate and the bottom inner wall of the device housing are provided with rotating grooves, and multiple rollers are rotatably installed in the rotating grooves, with the top and bottom of the cam respectively rotatably connected to the rollers.

[0012] Furthermore, the swing mechanism includes a groove on the inner wall of the bottom of the U-shaped base, a mounting plate fixedly installed at the rear end of the inner wall of the bottom side of the groove, an electric telescopic cylinder arranged in the front-rear direction fixedly installed on the front side of the mounting plate, a straight rack arranged in the front-rear direction fixedly connected to the output end of the electric telescopic cylinder, a broken gear fixedly installed at the center of the bottom of the device housing, and the straight rack meshing with the bottom of the broken gear; swing shafts are fixedly installed on both sides of the outer side of the device housing, bearings are fixedly installed on the side wall of the U-shaped base, and the outer end of the swing shaft is rotatably installed on the bearing; the broken gear also swings around the swing shaft.

[0013] Furthermore, guide rails arranged in the front-to-back direction are fixedly installed on the inner walls of the bottom side of the U-shaped base located on both sides of the groove, and sliding guide rods are fixedly connected to both sides of the rack, with the outer ends of the sliding guide rods slidably installed on the guide rails in the front-to-back direction.

[0014] Furthermore, the top of the mixing inner cylinder is provided with a feed inlet, and an end cap is provided on the feed inlet; a discharge hose is fixedly connected to the left side of the mixing inner cylinder, a discharge pump is fixedly installed on the outside of the device housing, and the other end of the discharge hose is connected to the suction end of the discharge pump.

[0015] Furthermore, both ends of the lifting plate are fixedly connected to a first sliding block, and both sides of the inner wall of the device housing are fixedly provided with a first slide rail, and the first sliding block is slidably installed on the first slide rail in the vertical direction; both sides of the inner wall of the device housing are fixedly provided with a second slide rail, and both sides of the mixing inner cylinder are fixedly connected to a second sliding block, and the second sliding block is slidably installed on the second slide rail in the vertical direction.

[0016] Furthermore, a controller is also provided on the upper front side of the device housing, and the controller is electrically connected to the electric telescopic cylinder, the dual-shaft extension motor, and the discharge pump.

[0017] The beneficial effects of this invention are:

[0018] 1. In this invention, the output shaft of the dual-shaft motor drives the stirring shaft, the spiral mixing blades, and the mixing rod to rotate. In this way, the rotation of the mixing rod can be used to stir and mix the ingredients.

[0019] 2. In this invention, the rotation of the spiral mixing blades can also spirally output the bottom material in the mixing cylinder from bottom to top, and then the material is stirred by the rotation of the mixing rod, so that the bottom material and the upper material can be fully exchanged and mixed, which is beneficial to the full and uniform mixing of the ingredients.

[0020] 3. In this invention, when the dual-shaft extension motor is working, it also drives the worm to rotate through the lower output shaft. When the worm rotates, it meshes with the worm wheel to drive the rotating shaft and the cam to rotate. When the cam rotates, it can make the mixing inner cylinder vibrate up and down, thereby further vibrating and mixing the ingredients in the mixing inner cylinder.

[0021] 4. In this invention, the functions of vibrating and mixing, rotating and stirring, and spiral mixing of various ingredients in the mixing cylinder can be realized by working with only one dual-shaft extension motor. This allows for the full exchange and mixing of ingredients in different positions, which is beneficial for more thorough and uniform mixing of various ingredients and greatly improves the mixing efficiency.

[0022] 5. In this invention, by setting a swing mechanism, the missing gear and the device housing can swing back and forth in the front and back direction on the bearing through the swing shaft. The device housing then drives the mixing inner cylinder to swing back and forth in the front and back direction, which can further promote the back and forth mixing of the ingredients in different positions in the mixing inner cylinder.

[0023] In summary, the mixing and batching device for producing resin grinding wheels not only achieves three functions—up-and-down vibration mixing, rotational stirring mixing, and bottom-to-top spiral mixing—through the operation of a single dual-shaft extension motor, but also mixes the ingredients at different positions within the mixing cylinder by oscillating back and forth. Furthermore, the simultaneous operation of all four mixing functions further reduces mixing time, resulting in more efficient mixing, better mixing effects, and significantly meeting current application needs.

[0033] The present invention will be further explained below with reference to specific embodiments.

[0034] Example

[0035] refer to Figure 1-8 This embodiment proposes a batching and mixing device for resin grinding wheel production, including a U-shaped base 1, a swing mechanism on the inner side of the U-shaped base 1, and a device housing 2 movably installed inside the U-shaped base 1 through the swing mechanism. A mixing inner cylinder 3 for mixing the batching materials used in resin grinding wheel production is also movably installed in the device housing 2 along the vertical direction.

[0036] A lifting plate 17 is movably installed inside the outer casing 2 of the device located below the mixing inner cylinder 3. The top two sides of the lifting plate 17 are also fixedly connected to the bottom side of the mixing inner cylinder 3 through the support frame 16. A dual-shaft extension motor 12 is fixedly installed at the bottom center of the mixing inner cylinder 3. The upper output shaft of the dual-shaft extension motor 12 rotates through the mixing inner cylinder 3 and is fixedly connected to the stirring shaft 13. Spiral mixing blades 14 are also fixedly installed on the stirring shaft 13.

[0037] The lower output shaft of the dual-shaft extension motor 12 rotates through to the bottom of the lifting plate 17 and is fixedly connected to a worm gear 20.

[0038] In this example, vertical grooves 243 are provided on the rear inner walls of both vertical frames 24, and vertical sliders 242 are fixedly connected to the rear sides of both rotating seats 241.

[0039] In this example, the spiral mixing direction of the spiral mixing blade 14 is specifically set to spiral output from bottom to top; both sides of the spiral mixing blade 14 are fixedly connected with mixing rods 15 arranged in upper and lower layers.

[0040] In this example, the bottom side of the lifting plate 17 and the bottom inner wall of the device housing 2 are provided with rotating grooves. Multiple rollers 231 are rotatably installed in the rotating grooves, and the top and bottom of the cam 23 are respectively connected to the rollers 231 in a rolling manner.

[0041] In this example, the swing mechanism includes a groove 101 on the inner wall of the bottom of the U-shaped base 1. A mounting plate 4 is fixedly installed at the rear end of the inner wall of the bottom side of the groove 101. An electric telescopic cylinder 5 arranged in the front-rear direction is fixedly installed on the front side of the mounting plate 4. A rack 6 arranged in the front-rear direction is fixedly connected to the output end of the electric telescopic cylinder 5. A broken gear 7 is fixedly installed at the center of the bottom of the device housing 2, and the rack 6 and the bottom of the broken gear 7 are engaged in transmission. Swing shafts 8 are fixedly installed on both sides of the outer side of the device housing 2. Bearings 9 are fixedly installed on the side wall of the U-shaped base 1, and the outer end of the swing shaft 8 is rotatably installed on the bearing 9. The broken gear 7 also swings around the swing shaft 8.

[0042] In this example, guide rails 11 arranged in the front-back direction are fixedly installed on the bottom inner walls of the U-shaped base 1 on both sides of the groove 101. Sliding guide rods 10 are fixedly connected to both sides of the rack 6, and the outer ends of the sliding guide rods 10 are slidably installed on the guide rails 11 in the front-back direction.

[0043] In this example, the top of the mixing inner cylinder 3 is provided with a feed inlet 301, and the feed inlet 301 is provided with an end cap; the left side of the mixing inner cylinder 3 is fixedly connected with a discharge hose 302, and the outside of the device housing 2 is fixedly installed with a discharge pump 303, and the other end of the discharge hose 302 is connected to the suction end of the discharge pump 303.

[0044] In this example, both ends of the lifting plate 17 are fixedly connected to the first sliding block 18, and the inner walls of both sides of the device housing 2 are fixedly provided with the first slide rail 19, and the first sliding block 18 is slidably installed on the first slide rail 19 in the vertical direction; the inner walls of both sides of the device housing 2 are fixedly provided with the second slide rail, and the upper parts of both sides of the mixing inner cylinder 3 are fixedly connected with the second sliding block, and the second sliding block is slidably installed on the second slide rail in the vertical direction.

[0045] The device housing 2 is equipped with a controller 25 on the upper front side, and the controller 25 is electrically connected to the electric telescopic cylinder 5, the dual-shaft extension motor 12, and the discharge pump 303.

[0046] like Figure 1-8 The diagram illustrates a mixing and batching device for resin grinding wheel production. When multiple ingredients need to be mixed during resin grinding wheel production, the various ingredients required for resin grinding wheel production are loaded into the mixing inner cylinder 3. Then, a dual-shaft extension motor 12 operates, driving the stirring shaft 13 to rotate via its upper output shaft. This, in turn, drives the spiral mixing blades 14 and the mixing rod 15 to rotate. The rotation of the mixing rod 15 thus stirs and mixes the ingredients. Simultaneously, the rotation of the spiral mixing blades 14 also spirally conveys the material from the bottom of the mixing inner cylinder 3 upwards. After being discharged, the material is then stirred by the rotation of the mixing rod 15, which allows for thorough exchange and mixing of the bottom and upper materials, facilitating a fully uniform mixing of the ingredients. Simultaneously, the dual-shaft extension motor 12 drives the worm gear 20 to rotate via its lower output shaft. The worm gear 20 meshes with the worm wheel 21, driving the rotating shaft 22 and cam 23 to rotate. The cam 23 also engages with the rollers 231 in the upper and lower positions. When the protruding part of the cam 23 rotates to a vertical position, it can cause the lifting plate 17, support frame 16, device housing 2, and mixing inner cylinder 3 to move upwards (e.g., ...). Figure 2 , Figure 3 , Figure 5 (As shown); when the protruding part of cam 23 rotates to a horizontal position, it can cause the lifting plate 17, support frame 16, device housing 2, and mixing inner cylinder 3 to move downwards (as shown). Figure 6 , Figure 7 , Figure 8 (As shown); Finally, through the continuous rotation of the cam 23, the mixing cylinder 3 can vibrate up and down, thereby further vibrating and mixing the ingredients in the mixing cylinder 3. With only the operation of a single dual-shaft extension motor 12, the functions of vibrating and mixing, rotating and stirring, and spiral mixing of various ingredients in the mixing cylinder 3 can be realized. This allows for the full exchange and mixing of ingredients in different positions, which is beneficial for more thorough and uniform mixing of various ingredients and greatly improves the mixing efficiency.

[0047] As a further implementation, during the mixing process, the extension and retraction of the output end of the electric telescopic cylinder 5 in the swing mechanism drives the rack 6 to move back and forth in the front-to-back direction. When the rack 6 moves, it also meshes with the missing gear 7, which in turn allows the missing gear 7 and the device housing 2 to swing back and forth in the front-to-back direction on the bearing 9 via the swing shaft 8. The device housing 2 then drives the mixing inner cylinder 3 to swing back and forth in the front-to-back direction. This further promotes the back-and-forth swinging and mixing of the ingredients at different positions in the mixing inner cylinder 3. Moreover, the swinging and mixing of the ingredients in the mixing inner cylinder 3 can be carried out simultaneously with the up-and-down vibration mixing, rotational stirring mixing, and bottom-up spiral mixing, which helps to further reduce the mixing time, making the mixing of ingredients more efficient and the mixing effect better, greatly meeting the current usage needs.

[0048] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
