[0002] In the production process of bonded permanent magnets, it is generally necessary to stir and mix permanent magnet powder, adhesive and additives. Generally, the permanent magnet powder is added intermittently while the materials are continuously stirred to avoid agglomeration caused by adding the permanent magnet powder at one time, which affects the final stirring effect.

[0003] A quantitative vertical rotary feeder is disclosed in the patent document with the publication number CN115057255A, which includes a feeder housing, an impeller, a frequency conversion motor, a stirring frame and a rotating mechanism. The feeder housing is provided with an impeller for rotation, the bottom of the feeder housing is provided with a frequency conversion motor, the output shaft of the frequency conversion motor is provided with a stirring frame, and the impeller is provided with a quantity control mechanism for controlling the amount of material in the material cavity. The quantitative vertical rotary feeder can perform intermittent quantitative conveying while continuously stirring the material, prevent agglomeration, and facilitate material conveying. However, the invention has the following shortcomings when used: the impeller rotates once to make the material cavity at one place face the discharge pipe. If the material in the cavity does not completely enter the discharge pipe, insufficient material feeding will be caused.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figure 1-Figure 11 As shown, the technical solution adopted by the present invention is as follows: a feeding device for bonding permanent magnet processing, comprising a base 1, a barrel 5, a ramp block 10 and a ramp push rod 30. In the process of bonding permanent magnets, permanent magnet powder, adhesive and additives need to be added to a mixing tank for stirring and mixing. The base 1 is provided with a discharge port that matches the mixing tank, and the base 1 is provided with a mounting block 2. When the base 1 is mounted to the mixing tank through the mounting block 2, the discharge port matches the feeding port of the mixing tank.

[0021] The base 1 is provided with a bottom plate 3 for sliding movement, and the bottom plate 3 slides left and right on the base 1. Figure 1 , Figure 4 As shown, a plurality of fixed sleeves 4 are fixedly connected to the bottom plate 3 from left to right in sequence, and a barrel 5 is elastically arranged in each fixed sleeve 4 for upward and downward movement. The fixed sleeve 4 and the barrel 5 are coaxially arranged. Specifically, a plurality of first slide grooves 7 are provided at the lower end of the barrel 5, and the plurality of first slide grooves 7 are evenly distributed around the axis of the barrel 5. A slide rod 8 is slidably arranged in the first slide groove 7, and the slide rod 8 is fixedly connected to the bottom plate 3. A first spring 9 is sleeved on the slide rod 8, one end of the first spring 9 is fixedly connected to the barrel 5, and the other end of the first spring 9 is fixedly connected to the bottom plate 3.

[0022] A fixed tube 6 is coaxially arranged in the fixed sleeve 4, the lower end of the fixed tube 6 is fixedly connected to the base plate 3, and the lower end of the fixed tube 6 passes through the base plate 3, the upper end of the fixed tube 6 is sealingly and slidingly matched with the lower end of the barrel 5 and is connected with the barrel 5, and the lower end of the inner wall of the barrel 5 is in a cone shape with the tip pointing downward, so that the material in the barrel 5 can flow into the fixed tube 6.

[0023] Each fixing sleeve 4 is provided with a ramp block 10. The middle part of the ramp block 10 is rotatably mounted on the support frame through a rotating rod, and the support frame is fixedly mounted on the bottom plate 3. A torsion spring is sleeved on the rotating rod, one end of the torsion spring is fixedly connected to the ramp block 10, and the other end of the torsion spring is fixedly connected to the support frame.

[0024] A fixing frame 28 is fixedly mounted on one end of the base 1 near the discharge port, a cylinder 29 is fixedly mounted on the fixing frame 28, the telescopic end of the cylinder 29 is vertically downward, and a ramp push rod 30 is fixedly mounted on the telescopic end of the cylinder 29. The ramp push rod 30 cooperates with the ramp block 10.

[0025] like Figure 8 As shown, a protrusion is fixedly provided on one side of the fixed sleeve 4, a sliding cavity is provided in the protrusion, a sliding block 24 is slidably provided in the sliding cavity, the sliding block 24 is fixedly connected to a limiting rod 25, a second spring 26 is sleeved on the limiting rod 25, and the second spring 26 is fixedly connected between the sliding block 24 and the inner wall of the sliding cavity. Under the action of the second spring 26, the limiting rod 25 is located in the sliding cavity. A limiting hole 27 cooperating with the limiting rod 25 is provided on the inclined block 10. The limiting rod 25 is provided with a trigger assembly. When the material in the barrel 5 completely flows out, under the action of the trigger assembly, when the sliding block 24 moves outward, the limiting rod 25 moves outward and extends into the limiting hole 27. The inclined push rod 30 moves downward, pushing the inclined block 10 to move, and the inclined block 10 drives the fixed sleeve 4 to move, so that the bottom plate 3 moves, and then the next barrel 5 moves to the top of the discharge port.

[0026] The trigger assembly includes a magnet 20, an iron slider 22 and a connecting rope 23. A vertical slide groove 21 is provided on the inner wall of the fixed sleeve 4, and the iron slider 22 is arranged in the vertical slide groove 21 for moving up and down, and the connecting rope 23 is connected between the iron slider 22 and the sliding block 24. A first threading channel is provided on the inner wall of the protrusion, and the first threading channel connects the vertical slide groove 21 and the sliding cavity, and the connecting rope 23 is slidably arranged in the first threading channel. Initially, under the action of the second spring 26, the sliding block 24 is located at one end of the sliding cavity, and the iron slider 22 is located at the upper end of the vertical slide groove 21. When the iron slider 22 moves down along the vertical slide groove 21, the iron slider 22 pulls the sliding block 24 through the connecting rope 23, so that the sliding block 24 overcomes the elastic force of the second spring 26 and moves, and the limit rod 25 moves outward.

[0027] The magnet 20 is fixedly connected to the lower end of the barrel 5, and the magnet 20 is arranged in cooperation with the iron slider 22. As the material in the barrel 5 gradually decreases, the barrel 5 gradually moves upward, the magnet 20 gradually moves upward, and the attraction of the magnet 20 to the iron slider 22 gradually increases. When the material in the barrel 5 is completely out, the attraction of the magnet 20 to the iron slider 22 causes the iron slider 22 to move downward. When the material in the barrel 5 has not completely flowed out, the attraction of the magnet 20 to the iron slider 22 cannot cause the iron slider 22 to move downward. The barrel 5 is made of magnetic isolation material to prevent the permanent magnetic powder in the barrel 5 from affecting each other with the magnet 20 and the iron slider 22.

[0028] A knocking mechanism is arranged in the fixed sleeve 4. A rope 11 is connected to one end of the inclined surface block 10, and the rope 11 and the knocking mechanism are arranged in linkage. When there is material retained in the barrel 5, the inclined surface push rod 30 moves downward and acts on the inclined surface block 10, so that the end of the inclined surface block 10 connected to the rope 11 moves upward, and the rope 11 drives the knocking mechanism to move, so that the knocking mechanism knocks the barrel 5, causing the material in the barrel 5 to flow out.

[0029] The knocking mechanism includes a ring 16, a spring telescopic rod 17 and a spherical head 18. An arc-shaped slide groove is coaxially provided in the fixed sleeve 4, and an arc-shaped rod 12 is slidably provided in the arc-shaped slide groove, and the arc-shaped rod 12 is coaxially provided with the fixed sleeve 4. One end of the rope 11 slides downward and extends into the bottom plate 3, then passes through the bottom plate 3 and extends into the fixed sleeve 4, and extends into the arc-shaped slide groove and is fixedly connected with one end of the arc-shaped rod 12. A connecting block 13 is fixedly connected to the end of the arc-shaped rod 12 away from the rope 11, and an elastic rope 14 is fixedly connected to the end of the connecting block 13 away from the arc-shaped rod 12. A wire groove connected to one end of the arc-shaped slide groove is provided in the fixed sleeve 4, and the elastic rope 14 extends into the wire groove and is fixedly connected to the end wall of the wire groove away from the end of the arc-shaped slide groove.

[0030] The annular member 16 is connected to the connecting block 13 through the one-way bearing 15. The connecting block 13 is fixedly connected to the outer ring of the one-way bearing 15, and the annular member 16 is fixedly connected to the inner ring of the one-way bearing 15. A plurality of spring telescopic rods 17 are installed on the annular member 16 along the circumferential direction, and the telescopic ends of the spring telescopic rods 17 face the barrel 5, and a spherical head 18 is connected to the telescopic ends of each spring telescopic rod 17.

[0031] A plurality of strip-shaped protrusions 19 are fixedly arranged on the outer circumference of the barrel 5. The strip-shaped protrusions 19 are arranged vertically and have a certain length. One side of the strip-shaped protrusions 19 is an inclined surface and the other side is a flat surface. When the end of the inclined block 10 connected to the rope 11 moves upward, the rope 11 pulls the arc rod 12 to move in the arc chute, and the arc rod 12 drives the connecting block 13 to move synchronously. The connecting block 13 drives the ring 16 to rotate around the axis of the barrel 5 through the one-way bearing 15, and the spring telescopic rod 17 and the spherical head 18 move synchronously. The spherical head 18 moves along the inclined surface of the strip protrusion 19. Under the pressure of the inclined surface, the spring telescopic rod 17 is gradually compressed. When the spherical head 18 passes over the inclined surface on the strip protrusion 19, since the other side of the strip protrusion 19 is a flat surface, the spring telescopic rod 17 quickly extends, and then the spherical head 18 knocks the barrel 5, causing the barrel 5 to vibrate, and then the material in the barrel 5 flows out. As the ring 16 rotates, under the action of multiple strip protrusions 19, the spherical head 18 continuously knocks the barrel 5.

[0032] A baffle 32 for shielding the discharge port is provided on the base 1. Specifically, a second slide groove 31 is provided on the base 1, and the baffle 32 is slidably arranged in the second slide groove 31. An electric control telescopic rod 33 is fixedly installed on the base 1, and the telescopic end of the electric control telescopic rod 33 is fixedly connected to the baffle 32.

[0033] An electric control slide rail 34 is installed on the base 1, and an electric control slider 35 is provided in conjunction with the electric control slide rail 34. A fixed block 36 is fixedly connected to the bottom of the bottom plate 3, and the fixed block 36 and the electric control slider 35 are provided in coordination. When the materials in the multiple barrels 5 are loaded, the electric control slider 35 pushes the fixed block 36, thereby resetting the bottom plate 3.

[0034] Working principle: The base 1 is fixedly connected to the mixing tank through the mounting block 2.

[0035] Initially, each barrel 5 is filled with a fixed amount of material, the first spring 9 is in a compressed state, and the slide bar 8 is at the top of the first slide groove 7. The sliding block 24 is located at the end of the sliding cavity away from the inclined block 10, the iron slider 22 is located at the upper end of the vertical slide groove 21, and the limit rod 25 is completely located in the sliding cavity. Under the action of the torsion spring, the end of the inclined block 10 connected to the rope 11 tilts downward. Under the action of the elastic rope 14, the connecting block 13 abuts against the end of the arc-shaped slide groove. One of the barrels 5 is opposite to the discharge port, and the baffle 32 blocks the discharge port. The end of the inclined block 10 corresponding to the discharge port that is away from the rope 11 is below the inclined push rod 30. The electric control slider 35 is at the end of the electric control slide rail 34 close to the discharge port, the fixed block 36 is close to the other end of the electric control slide rail 34, and the bottom plate 3 is on the base 1.

[0036] When loading, the electrically controlled telescopic rod 33 is started to move the baffle 32 in the second chute 31, thereby opening the discharge port, and the material in the barrel 5 above the discharge port flows out through the discharge port and enters the mixing tank.

[0037] As the material flows out, the barrel 5 gradually moves upward under the action of the first spring 9, and the magnet 20 gradually moves upward so that the magnet 20 gradually approaches the iron slider 22. The smaller the distance between the magnet 20 and the iron slider 22, the greater the attraction of the magnet 20 to the iron slider 22. As the magnet 20 moves upward, the attraction of the magnet 20 to the iron slider 22 gradually increases. However, when the material in the barrel 5 has not completely flowed out, the attraction of the magnet 20 to the iron slider 22 cannot move the iron slider 22 downward.

[0038] When the material in the barrel 5 has completely flowed out, the magnet 20 has an attractive force on the iron slider 22, causing the iron slider 22 to move downward along the vertical slide groove 21. The iron slider 22 pulls the sliding block 24 to move through the connecting rope 23, causing the limiting rod 25 to move outward and be inserted into the limiting hole 27.

[0039] The cylinder 29 makes the inclined push rod 30 reciprocate intermittently. The inclined push rod 30 moves downward and then moves upward to reset, which is a reciprocating motion. After each reciprocating motion, the inclined push rod 30 will pause for a period of time before the next reciprocating motion. The pause time of the inclined push rod 30 is greater than the normal emptying time of the barrel 5. That is to say, during the pause time of the inclined push rod 30, the material in the barrel 5 will be completely discharged under normal circumstances. By controlling the pause time of the inclined push rod 30, the intermittent feeding time can be controlled.

[0040] like Fig. 9 , Fig.10 , Fig.11 As shown, from right to left, when the material in the first barrel 5 is normally emptied, the inclined push rod 30 moves downward, and the inclined push rod 30 pushes the first inclined block 10, so that the first inclined block 10 moves to the right, and the first inclined block 10 drives the first fixed sleeve 4 to move right, and the bottom plate 3 moves to the right, so that the second barrel 5 moves to the top of the discharge port. The second inclined block 10 gradually approaches the inclined push rod 30, and the inclined push rod 30 pushes the second inclined block 10 away from the corresponding rope 11 to rotate upward by a certain angle. After the inclined push rod 30 moves upward, the second inclined block 10 is reset and is below the inclined push rod 30.

[0041] If the material in the barrel 5 is blocked and cannot be emptied, the attraction of the magnet 20 to the iron slider 22 cannot make the iron slider 22 move downward, and then the limit rod 25 cannot extend into the limit hole 27. When the inclined push rod 30 moves downward, the inclined push rod 30 pushes the inclined block 10 to rotate, so that the end of the inclined block 10 close to the rope 11 moves upward, and the inclined block 10 pulls the arc rod 12 to slide in the arc chute through the rope 11, and the connecting block 13 slides synchronously, and the connecting block 13 drives the ring 16 to rotate around the axis of the barrel 5 through the one-way bearing 15, and the spring telescopic rod 17 and the spherical head 18 both rotate around the axis of the barrel 5. The spherical head 18 slides along the inclined side of the strip protrusion 19, and under the pressure of the strip protrusion 19, the spring telescopic rod 17 is gradually compressed. When the spherical head 18 passes over the inclined surface of the strip protrusion 19 and enters the other side, since the other side of the strip protrusion 19 is a flat surface, the spring telescopic rod 17 quickly extends, so that the spherical head 18 knocks the barrel 5, causing the barrel 5 to vibrate, and then the material in the barrel 5 flows out. As the ring 16 rotates, the spherical head 18 continuously knocks the barrel 5 under the action of the multiple strip protrusions 19.

[0042] As the material in the barrel 5 flows out, the barrel 5 gradually moves upward. Since the strip-shaped protrusion 19 has a certain length, the spherical head 18 always keeps matching with the strip-shaped protrusion 19 .

[0043] When the inclined push rod 30 is reset, the inclined block 10 is reset under the action of the torsion spring, and the end of the inclined block 10 close to the rope 11 gradually tilts downward. After the pulling force of the rope 11 is lost, the arc rod 12 moves toward the direction close to the elastic rope 14 under the action of the elastic rope 14, and the connecting block 13 drives the outer ring of the one-way bearing 15 to rotate relative to the inner ring. Since the spherical head 18 abuts against the flat surface of the strip protrusion 19, the annular member 16 cannot rotate.

[0044] The end of the limit rod 25 close to the inclined plane block 10 is arc-shaped. If the end of the inclined plane block 10 close to the rope 11 gradually moves upward, the material in the barrel 5 is emptied, the barrel 5 moves upward, and the limit rod 25 extends. After the inclined plane push rod 30 is reset upward, under the action of the torsion spring, the end of the inclined plane block 10 close to the rope 11 will push the limit rod 25 during the downward movement, so that the limit rod 25 moves into the sliding cavity, and then the inclined plane block 10 is reset under the action of the torsion spring, and the limit rod 25 and the limit hole 27 are opposite. Under the action of the magnet 20, the iron slider 22 moves downward, and the limit rod 25 extends into the limit hole 27.

[0045] If the material in the barrel 5 is not emptied after the inclined push rod 30 performs a reciprocating motion, the limiting rod 25 cannot extend into the limiting hole 27. When the inclined push rod 30 performs the next reciprocating motion, the inclined push rod 30 pushes the inclined block 10 to rotate, thereby causing the knocking mechanism to knock the barrel 5, causing the material in the barrel 5 to be discharged. When the material in the barrel 5 is completely discharged, the limiting rod 25 extends into the limiting hole 27, and when the inclined push rod 30 moves downward, the bottom plate 3 moves, thereby causing the next barrel 5 to move above the discharge port.

[0046] During the loading process, as the bottom plate 3 moves, the fixed block 36 gradually approaches the electric control slider 35. When the materials in the multiple barrels 5 are loaded, the electric control slide 34 is started, and the electric control slider 35 pushes the fixed block 36 to reset the bottom plate 3, and then reset the electric control slider 35 to the end of the electric control slide 34 close to the discharge port.

[0047] A fixed amount of material is added into the barrel 5 , and the barrel 5 moves downward. Under the action of the second spring 26 , the sliding block 24 moves, the limiting rod 25 escapes from the limiting hole 27 , and the iron slider 22 moves to the upper end of the vertical slide groove 21 .
