Description

Technical Field

[0001] The invention relates to the technical field of ball mill abrasive sorting devices, in particular to a tetrahedron abrasive sorting device and a use method thereof. Background Art

[0002] The ball mill is a device used to crush materials. The working principle of the ball mill is that the motor drives the cylinder to rotate, and the abrasive in the cylinder is brought to a certain height under the action of centrifugal force and then falls down, impacting and grinding the material.

[0003] The abrasive material commonly used in ball mills is steel balls. The friction between the steel balls and the material produces a grinding effect. To improve the grinding effect, see Fig.11 Currently, tetrahedral abrasives have been developed. Compared with steel balls, tetrahedral abrasives have more edges and corners. When grinding ore blocks, the edges and corners are easier to break the ore blocks, and the grinding effect is better.

[0004] When processing tetrahedral abrasives, an air hammer is used to forge the red-hot blank in the lower die to forge the blank into a tetrahedral structure. Due to factors such as insufficient blank quality and mismatch between the blank and the die, the tetrahedral abrasive has corner defects after forging. Fig.12 .

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. The sorting device of the present invention can sort out tetrahedral abrasives with damaged edges and corners without manual sorting, which can save manpower and improve sorting efficiency; and avoid negligence caused by the workers' state, which is conducive to improving sorting accuracy.

[0038] 2. The sorting device of the present invention can be placed on one side of the air hammer so that the air hammer can forge the tetrahedral abrasive while performing the sorting operation, which is beneficial to further improve the sorting efficiency.

[0039] 3. By mechanically sorting tetrahedral abrasives with angular defects, it is possible to avoid the inclusion of defective products during subsequent heat treatment, which is beneficial to saving energy.

[0040] 4. By setting a vibration mechanism, the tetrahedron abrasive located between the two horizontal rods can adjust its posture, and the tetrahedron abrasive can be transformed from an unstable posture to a stable posture. The stable posture is that the first edge of the tetrahedron abrasive enters between the two horizontal rods. At this time, the two horizontal rods are in contact with the two planes of the tetrahedron abrasive. The contact area between the tetrahedron abrasive and the two horizontal rods is the largest, so the tetrahedron abrasive is in a stable posture. After entering the stable state, it is more convenient for the first detection mechanism and the second detection mechanism to detect whether there are missing edges and corners, and there is no need to manually adjust the posture of the tetrahedron abrasive, which is conducive to further saving manpower.

[0041] 5. Through the vibration and the sliding inertia of the tetrahedral abrasive, the tetrahedral abrasive can be driven to continue to enter between the two first guide rails from between the two horizontal rods while adjusting its posture, and then slide down along the first guide rail to pass through the first detection element, thereby realizing the continued transportation of the tetrahedral abrasive, reducing the probability of the tetrahedral abrasive being stuck, and improving the reliability of the sorting operation of the entire device.

[0042] 6. The first rejecting mechanism and the second rejecting mechanism of the present invention can release and reject unqualified tetrahedral abrasives downward, which can fully utilize the vertical space and improve the space utilization rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0075] The first detection mechanism is used to detect whether the tetrahedral abrasive 1 on the first transmission mechanism lacks the third corner 13 and the fourth corner 14.

[0076] When the two first guide rails 21 clamp the first edge 15 of the tetrahedral abrasive 1, the third corner 13 of the tetrahedral abrasive 1 is located below one first detection frame 51, and the fourth corner 14 is located below the other first detection frame 51. At this time, the first detection elements on the two first detection frames 51 can respectively detect whether the tetrahedral abrasive 1 lacks the third corner 13 and the fourth corner 14.

[0077] See also Figure 2 A first notch is provided on the first guide rail 21, and the first notch is provided behind the first detection element. A first movable rail 211 is provided at the first notch.

[0078] See also Figure 2 The first rejection mechanism is used to reject the tetrahedral abrasive 1 that lacks the third corner 13 and / or the fourth corner 14. In the present embodiment 1, the first rejection mechanism includes a first rejection frame 61, a first telescopic rod 62 and a first swing arm 63. The first rejection frame 61 is fixedly installed between the two first detection frames 51, and the first telescopic rod 62 is fixedly installed on the first rejection frame 61. The first telescopic rod 62 can be an oil cylinder, an air cylinder or an electric push rod. The output end of the first telescopic rod 62 is fixedly installed with a first sliding pin 621. The middle part of the first swing arm 63 is rotatably connected to the first detection frame 51. The upper part of the first swing arm 63 is provided with a first long hole 631. The first sliding pin 621 is arranged in the first long hole 631. The lower part of the first swing arm 63 is fixedly connected to the first movable rail 211.

[0079] The first detection element and the first telescopic rod 62 are both electrically connected to the control module.

[0080] When the first detection element detects that the tetrahedral abrasive 1 lacks the third corner 13 and / or the fourth corner 14, the control module controls the output end of the first telescopic rod 62 to retract, and the output end of the first telescopic rod 62 pulls the upper part of the first swing arm 63, so that the lower end of the first swing arm 63 drives the first movable rail 211 to lift, so that the tetrahedral abrasive 1 lacking the third corner 13 and / or the fourth corner 14 falls from between the two first guide rails 21, and the removal operation is achieved. In the process of the output end of the first telescopic rod 62 pulling the upper part of the first swing arm 63, the first sliding pin 621 slides up in the first long hole 631.

[0081] See also Figure 2 In order to facilitate the collection of the rejected tetrahedral abrasive 1, the first rejection mechanism also includes a first guide groove body 64, and a collection container can be placed at the end of the first guide groove body 64. For example, a collection basket can be used as a collection container. The tetrahedral abrasive 1 that falls from between the two first guide rails 21 falls into the first guide groove body 64, and then slides into the collection container through the first guide groove body 64.

[0082] When the first detection element does not detect that the tetrahedral abrasive 1 lacks the third corner 13 and the fourth corner 14, the control module controls the output end of the first telescopic rod 62 to remain extended. At this time, the first movable rail 211 located at the lower end of the first swing arm 63 is located in the first notch, and the tetrahedral abrasive 1 that does not lack the third corner 13 and the fourth corner 14 slides smoothly over the first movable rail 211 to reach the end of the first guide rail 21.

[0083] See also Figure 4 The second detection mechanism is used to detect whether the tetrahedral abrasive 1 on the second transmission mechanism lacks the first corner 11 and the second corner 12. In the present embodiment 1, the second detection mechanism includes a second detection frame 71 and a second detection element, and the second detection frames 71 are fixedly installed on the upper side of the two second guide rails 31 away from each other, and the two second detection frames 71 are fixedly installed with second detection elements.

[0084] When the tetrahedral abrasive 1 slides to the end of the two first guide rails 21, the first edge 11 or the second edge 12 of the tetrahedral abrasive 1 abuts against the flip rod 41, and the tetrahedral abrasive 1 flips around the flip rod 41 under the action of the sliding inertia, so that the second edge 16 of the tetrahedral abrasive 1 flips to between the two second guide rails 31, and the first edge 11 is located below one second detection frame 71, and the second edge 12 is located below the other second detection frame 71. At this time, the second detection elements on the two second detection frames 71 respectively detect whether the tetrahedral abrasive 1 lacks the first edge 11 and the second edge 12.

[0085] See also Figure 5A second notch is provided on the second guide rail 31, and the second notch is provided behind the second detection element. A second movable rail 311 is provided at the second notch.

[0086] See also Figure 5 The second rejection mechanism is used to reject the tetrahedral abrasive 1 that lacks the first corner 11 and / or the second corner 12. In the present embodiment 1, the second rejection mechanism includes a second rejection frame 81, a second telescopic rod 82 and a second swing arm 83. The second rejection frame 81 is fixedly installed between the two second detection frames 71, and the second telescopic rod 82 is fixedly installed on the second rejection frame 81. The second telescopic rod 82 can also adopt an oil cylinder or an air cylinder or an electric push rod.

The second sliding pin 821 is arranged in the second long hole 831, and the lower part of the second swing arm 83 is fixedly connected to the second movable rail 311.

[0087] The second detection element and the second telescopic rod 82 are also electrically connected to the control module.

[0088] When the second detection element detects that the tetrahedral abrasive 1 lacks the first corner 11 and / or the second corner 12, the control module controls the output end of the second telescopic rod 82 to retract, and the output end of the second telescopic rod 82 pulls the upper part of the second swing arm 83, so that the lower end of the second swing arm 83 drives the second movable rail 311 to lift, so that the tetrahedral abrasive 1 lacking the first corner 11 and / or the second corner 12 falls from between the two second guide rails 31, and the removal operation is realized. In the process of the output end of the second telescopic rod 82 pulling the upper part of the second swing arm 83, the second sliding pin 821 slides up in the second long hole 831.

[0089] See also Figure 4 In order to facilitate the collection of the rejected tetrahedral abrasive 1, the second rejection mechanism also includes a second guide groove body 84, and a collection container can be placed at the end of the second guide groove body 84. The ends of the first guide groove body 64 and the second guide groove body 84 can share a collection container. The tetrahedral abrasive 1 that falls from between the two second guide rails 31 falls into the second guide groove body 84, and then slides from the second guide groove body 84 into the collection container.

[0090] When the second detection element does not detect that the tetrahedral abrasive 1 lacks the first corner 11 and the second corner 12, the control module controls the output end of the second telescopic rod 82 to remain extended. At this time, the second movable rail 311 located at the lower end of the second swing arm 83 is located in the second notch. The tetrahedral abrasive 1 that is not missing the first corner 11 and the second corner 12 slides smoothly over the second movable rail 311 to reach the end of the second guide rail 31. Finally, the tetrahedral abrasive 1 that slides out from the end of the second guide rail 31 is complete.

[0091] Embodiment 2:

[0092] In this embodiment 2, a form of the first detection element and the second detection element is given:

[0093] See also Figures 1 to 10 , the first detection element and the second detection element can both use photoelectric sensors. Specifically, a through-beam photoelectric sensor can be used. The through-beam photoelectric sensor is an existing product. The through-beam photoelectric sensor includes a transmitter 201 and a receiver 202. The light emitted by the transmitter 201 directly enters the receiver 202. When an object blocks the light, it means that an object has passed. When no object blocks the light, it means that no object has passed.

[0094] See also Figure 1 and Figure 3 In the present embodiment 2, when a through-beam photoelectric sensor is used as the first detection element, the emitter 201 is fixedly mounted on the upper portion of the first detection frame 51, a first window 511 is provided on the upper portion of the first detection frame 51, the light emitted by the emitter 201 passes downward from the first window 511, and the receiver 202 is fixedly mounted on the side of the first guide rail 21, and the receiver 202 is used to receive the light emitted from the emitter 201.

[0095] If the third corner 13 of the tetrahedral abrasive 1 passes through the through-beam photoelectric sensor, the third corner 13 blocks the light emitted by the emitter 201, indicating that the third corner 13 is not missing. The through-beam photoelectric sensor generates a signal and transmits it to the control module. The control module controls the output end of the first telescopic rod 62 to remain in the extended state, and the first movable rail 211 to remain in the first notch, so that the tetrahedral abrasive 1 without the third corner 13 can slide smoothly to the end of the first guide rail 21.

[0096] If the tetrahedral abrasive 1 lacks the third corner 13, the receiver 202 of the through-beam photoelectric sensor successfully receives the light from the transmitter 201, and the through-beam photoelectric sensor generates a signal to transmit to the control module, and the control module controls the output end of the first telescopic rod 62 to retract, so that the first movable rail 211 is lifted, and when the tetrahedral abrasive 1 lacking the third corner 13 slides to the first notch, the tetrahedral abrasive lacking the third corner 13 falls into the first guide groove 64, so as to remove the tetrahedral abrasive 1 lacking the third corner 13.

[0097] The same principle applies when detecting whether the fourth corner 14 is missing.

[0098] See also Figure 4 and Figure 6In the present embodiment 2, when a through-beam photoelectric sensor is used as the second detection element, the emitter 201 is fixedly mounted on the upper portion of the second detection frame 71, a second window 711 is provided on the upper portion of the second detection frame 71, the light emitted by the emitter 201 passes downward from the second window 711, and the receiver 202 is fixedly mounted on the side of the second guide rail 31, and the receiver 202 is used to receive the light emitted by the emitter 201.

[0099] If the first edge 11 of the tetrahedral abrasive 1 passes through this through-beam photoelectric sensor, the first edge 11 blocks the light emitted by the emitter 201, indicating that the first edge 11 is not missing. This through-beam photoelectric sensor generates a signal and transmits it to the control module. The control module controls the output end of the second telescopic rod 82 to remain in an extended state, and the second movable rail 311 to remain in a state located in the second notch, so that the tetrahedral abrasive 1 without missing the first edge 11 can slide smoothly to the end of the second guide rail 31.

[0100] If the tetrahedral abrasive 1 lacks the first corner 11, the receiver 202 of the through-beam photoelectric sensor successfully receives the light from the transmitter 201, and the through-beam photoelectric sensor generates a signal and transmits it to the control module. The control module controls the output end of the second telescopic rod 82 to retract, so that the second movable rail 311 is lifted, so as to remove the tetrahedral abrasive 1 lacking the first corner 11.

[0101] The same principle applies when detecting whether the second corner 12 is missing.

[0102] Embodiment 3:

[0103] This embodiment 3 provides a second form of the first detection element and the second detection element:

[0104] The first detection element and the second detection element can both adopt micro switches. The micro switches are existing products. The working principle of the micro switches is to use external mechanical force to act on the transmission element of the micro switch to deform the action reed of the micro switch. When the deformation reaches the critical point, the moving contact and the fixed contact are quickly connected, thereby realizing the connectivity of the circuit.

[0105] In the third embodiment, when a micro switch is used as the first detection element, the micro switch is fixedly mounted on the upper portion of the first detection frame 51 .

[0106] If the third edge 13 of the tetrahedral abrasive 1 passes through the micro switch, the third edge 13 touches the transmission element of the micro switch, so that the micro switch generates a signal to be transmitted to the control module, indicating that the third edge 13 is not missing. The control module controls the output end of the first telescopic rod 62 to remain in the extended state, and the first movable rail 211 to remain in the first notch, so that the tetrahedral abrasive 1 without the third edge 13 can slide smoothly to the end of the first guide rail 21.

[0107] If the tetrahedral abrasive 1 lacks the third corner 13, the transmission element of the micro switch will not be triggered, and the micro switch generates a signal to be transmitted to the control module. The control module controls the output end of the first telescopic rod 62 to retract, so that the first movable rail 211 is lifted, so as to remove the tetrahedral abrasive 1 lacking the third corner 13.

[0108] The same principle applies when detecting whether the fourth corner 14 is missing.

[0109] In the third embodiment, when a micro switch is used as the second detection element, the micro switch is fixedly mounted on the upper portion of the second detection frame 71 .

[0110] If the first edge 11 of the tetrahedral abrasive 1 passes through the micro switch, the first edge 11 touches the transmission element of the micro switch, so that the micro switch generates a signal to transmit to the control module, indicating that the first edge 11 is not missing. The control module controls the output end of the second telescopic rod 82 to remain in an extended state, and the second movable rail 311 to remain in a state located in the second notch, so that the tetrahedral abrasive 1 without missing the first edge 11 can slide smoothly to the end of the second guide rail 31.

[0111] If the tetrahedral abrasive 1 lacks the first corner 11, the transmission element of the micro switch will not be triggered, and the micro switch generates a signal to be transmitted to the control module. The control module controls the output end of the second telescopic rod 82 to retract, so that the second movable rail 311 is lifted, so as to remove the tetrahedral abrasive 1 lacking the first corner 11.

[0112] The same principle applies when detecting whether the second corner 12 is missing.

[0113] Embodiment 4:

[0114] This embodiment 4 is further improved on the basis of embodiment 1:

[0115] See also Figures 1 to 10 In this embodiment 4, a horizontal rod 212 is fixedly installed at the starting end of the two first guide rails 21, and an inclined rod 213 is fixedly installed at the end of the two horizontal rods 212 away from the first guide rails 21, and the inclined rod 213 is inclined toward the side away from the horizontal rod 212.

[0116] See also Fig.10The two tilting rods 213 are used to receive the tetrahedral abrasive 1 after forging by the air hammer 9. Before the two tilting rods 213 receive the tetrahedral abrasive 1, the upper ends of the two tilting rods 213 need to be abutted against the side wall of the lower die 91 in the air hammer 9. After the tetrahedral abrasive 1 is forged, the worker can push the tetrahedral abrasive 1 in the lower die 91 onto the two tilting rods 213. The tetrahedral abrasive 1 located between the two tilting rods 213 slides down from the tilting rods 213 to between the two horizontal rods 212.

[0117] Also, see Figure 3 In a tetrahedral abrasive sorting device of the present embodiment 4, a vibration mechanism is also included, and the vibration mechanism includes a fixed cylinder 101, a movable rod 102, a mounting plate 103, a vibration motor 104 and a reset spring 105. The fixed cylinder 101 is fixedly installed on the ground, and a movable rod 102 is arranged inside the fixed cylinder 101, and the movable rod 102 is vertically slidably matched with the inside of the fixed cylinder 101, and the top of the movable rod 102 is welded and fixed to the horizontal rod 212, and the mounting plate 103 is fixedly installed on the movable rod 102, and the vibration motor 104 is fixedly installed on the mounting plate 103, and the reset spring 105 is sleeved on the movable rod 102, and the top of the reset spring 105 abuts against the mounting plate 103, and the bottom of the reset spring 105 abuts against the top of the fixed cylinder 101.

[0118] When the vibration motor 104 is started, the vibration motor 104 drives the mounting plate 103 to vibrate, the mounting plate 103 drives the movable rod 102 to vibrate, the movable rod 102 drives the first guide rail 21 to vibrate, and the first guide rail 21 drives the horizontal rod 212 and the tilting rod 213 to vibrate. During the vibration process, the reset spring 105 is compressed and restored reciprocatingly, and the movable rod 102 slides up and down in the fixed tube 101.

[0119] Through the vibration, the tetrahedral abrasive 1 between the two horizontal rods 212 can adjust its posture, so that the tetrahedral abrasive 1 can be transformed from an unstable posture to a stable posture. The unstable posture is that one edge of the tetrahedral abrasive 1 enters between the two horizontal rods 212. At this time, the tetrahedral abrasive 1 is in a top-heavy state, so it is unstable. The stable posture is that the first edge 15 of the tetrahedral abrasive 1 enters between the two horizontal rods 212. At this time, the two horizontal rods 212 are in contact with two planes of the tetrahedral abrasive 1. The contact area between the tetrahedral abrasive 1 and the two horizontal rods 212 is the largest, so the tetrahedral abrasive 1 is in a stable posture.

[0120] Furthermore, through the vibration and the sliding inertia of the tetrahedral abrasive 1, the tetrahedral abrasive 1 can be driven to continue to enter between the two first guide rails 21 from between the two horizontal rods 212 while adjusting its posture, and then slide down along the first guide rails 21 through the first detection element, thereby realizing the continued transportation of the tetrahedral abrasive 1.

[0121] Because the horizontal rod 212 is located at the beginning of the first guide rail 21, and the horizontal rod 212 is supported by the fixed cylinder 101, the movable rod 102 and the reset spring 105 in the vibration mechanism, and the end of the first guide rail 21 is in a suspended state, the stability of the end of the first guide rail 21 needs to be improved. In this regard, an auxiliary rod 215 is welded and fixed at the end of the first guide rail 21, and the auxiliary rod 215 is vertically slidably matched with the auxiliary cylinder 214, and the auxiliary cylinder 214 is fixedly installed on the ground. The auxiliary rod 215 is also sleeved with an auxiliary spring 216, and the upper end of the auxiliary spring 216 abuts against the first guide rail 21, and the lower end of the auxiliary spring 216 abuts against the auxiliary cylinder 214. When the vibration mechanism drives the first guide rail 21, the horizontal rod 212 and the inclined rod 213 to vibrate, the auxiliary rod 215 at the end of the first guide rail 21 slides vertically inside the auxiliary cylinder 214, and the auxiliary spring 216 is compressed and restored in this process, so that the end of the first guide rail 21 can be supported by the auxiliary rod 215, the auxiliary cylinder 214 and the auxiliary spring 216, thereby improving the stability of the entire first guide rail 21.

[0122] Embodiment 5:

[0123] A method for using a tetrahedron abrasive sorting device, based on Embodiment 4, comprises the following steps:

[0124] S1, the top end of the tilting rod 213 is abutted against the side of the lower mold 91 of the air hammer 9, and the vibration motor 104 is started;

[0125] S2. When the air hammer 9 forges the tetrahedron abrasive 1 to be sorted, the worker moves the tetrahedron abrasive 1 between the two inclined rods 213, and the tetrahedron abrasive 1 slides down along the inclined rods 213 to between the two horizontal rods 212. Under the action of vibration, the tetrahedron abrasive 1 continues to enter the two first guide rails 21, and the first edge 15 of the tetrahedron abrasive 1 is clamped between the two first guide rails 21 and slides downward to pass through the first detection element;

[0126] S3, when the first detection element detects that the third corner 13 and / or the fourth corner 14 of the tetrahedral abrasive 1 is missing, the control module controls the output end of the first telescopic rod 62 to retract, so that the lower end of the first swing arm 63 drives the first movable rail 211 to lift, so that the tetrahedral abrasive 1 missing the third corner 13 and / or the fourth corner 14 is removed from the first guide rail 21;

[0127] S4, when the first detection element does not detect the lack of the third corner 13 and the fourth corner 14 of the tetrahedral abrasive 1, the tetrahedral abrasive 1 continues to slide downward until the first corner 11 or the second corner 12 of the tetrahedral abrasive 1 abuts against the flip rod 41, and the tetrahedral abrasive 1 flips under the action of the sliding inertia, and the second edge 16 of the tetrahedral abrasive 1 flips to between the two second guide rails 31, and the tetrahedral abrasive 1 slides down along the second guide rail 31 and passes through the second detection element;

[0128] S5. When the second detection element detects that the tetrahedral abrasive 1 lacks the first corner 11 and / or the second corner 12, the control module controls the output end of the second telescopic rod 82 to retract, so that the lower end of the second swing arm 83 drives the second movable rail 311 to lift, so that the tetrahedral abrasive 1 lacking the first corner 11 and / or the first corner 11 is removed from the second guide rail 31;

[0129] S6 . When the second detection element does not detect that the tetrahedral abrasive 1 lacks the first corner 11 and the second corner 12 , the tetrahedral abrasive 1 slides out from the end of the second guide rail 31 .

[0130] Through the above process, it can be seen that the tetrahedral abrasive sorting device of this embodiment has the following effects:

[0131] First, the sorting device of this embodiment can sort out tetrahedral abrasives 1 with damaged edges and corners without manual sorting, which can save manpower and improve sorting efficiency; and avoid negligence caused by the workers' state, which is conducive to improving sorting accuracy.

[0132] Second, the sorting device of this embodiment can be placed on one side of the air hammer 9 so that the air hammer 9 can forge the tetrahedral abrasive 1 while performing the sorting operation, which is beneficial to further improve the sorting efficiency.

[0133] Third, by mechanically sorting the tetrahedral abrasive 1 with angular defects, it is possible to avoid the inclusion of defective products during the subsequent heat treatment process, which is beneficial to saving energy.

[0134] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
