Description

Technical Field

[0001] The invention relates to the technical field of feeders, and in particular to an electromagnetic driven feeder. Background Art

[0002] Electromagnetic feeder is a highly efficient and new type of automatic feeding equipment that works on the principle of electromagnetic vibration. It is mainly used to uniformly and continuously transport granular, block or powdered materials from storage bins to various production equipment or processing equipment. The core component of the equipment is the electromagnetic vibrator, which is composed of key components such as coils, iron cores and vibration springs. When current flows through the coil, it will excite a magnetic field, which will act on the iron core, and then through the transmission of the vibration spring, the entire equipment will vibrate, thereby achieving continuous and uniform feeding of materials. Traditional electromagnetic vibration conveying equipment does not allow adjustment of the driver after assembly or requires disassembly of the entire driver when adjusting, which affects both work efficiency and product quality. Traditional electromagnetic vibration conveying equipment requires an elastic component between the trough and the base to increase the driving force, make the trough vibrate, and convey materials. The base is connected to the ground or a fixed position through a shock-absorbing rubber block or spring.

[0003] In traditional electromagnetic vibration conveying equipment, an elastic component is installed between the trough body and the connecting frame. When the material conveying amount per unit time changes, the conveying speed of the conveying equipment will change. This is because when the material amount per unit time changes, the force on the elastic component under the trough body will change. The weight on the trough body changes, causing the elastic component to deform, and then changing the trough body amplitude, thereby changing the conveying speed, making the material conveying speed inconsistent. Summary of the invention

[0004] In response to the above technical problems, the present invention discloses an electromagnetic driven feeder, including an electromagnetic driver and a trough body, the electromagnetic driver including a driver housing, a connecting plate fixedly mounted on the driver housing, a trough body connecting plate fixedly mounted on the outer side of the connecting plate, an elastic component fixedly mounted on the inner side of the connecting plate, counterweight pads connected to both ends of the elastic component, and a coil connecting plate connected to the lower end of the counterweight pad.

[0005] At the lower end of the coil connection plate, a counterweight and a coil are fixedly installed; inside the coil, a first iron core and a second iron core are arranged. The middle part of the elastic component is fixedly equipped with an armature. After the coil is energized, it attracts the armature to contact the second iron core. At the bottom of the driver housing, an iron core adjustment bolt is installed. The iron core adjustment bolt passes through the first iron core and is connected to the armature. Rotating the iron core adjustment bolt can control the distance between the second iron core and the armature. Through the technical solution of the present invention, using the iron core adjustment bolt to adjust the distance between the second iron core and the armature solves the problems that the driver is not allowed to be adjusted after assembly, or the entire driver needs to be disassembled during adjustment, which not only affects work efficiency, but also affects product quality during disassembly and assembly. The structure of this case is simple. The elastic component between the connecting frame and the trough body in the traditional structure is cancelled. Subsequently, the amount of material input into the trough body per unit time has no influence on the conveying speed of the equipment, thereby ensuring the consistency of the equipment conveying speed.

[0006] Further, the elastic component includes a plurality of leaf springs, and each leaf spring is separated by separator sheets at both ends.

[0007] Further, it also includes a base, on which a rubber block is fixedly installed, on which a trough body is fixedly installed, on which a connecting frame is fixedly installed, and the connecting frame is fixedly connected to the trough body connection plate.

[0008] Further, a guide seat is arranged on the driver housing, a chute is arranged at the middle position of the guide seat, a sliding bolt is slidably installed in the chute, and two support locking parts are slidably installed on the coil connection plate, located on both sides of the coil respectively. The support locking parts are located between the elastic component and the coil connection plate, and the sliding bolt cooperates with the support locking parts to fix the elastic component.

[0009] Further, the support locking part includes a plurality of gaskets, the gaskets are arranged alternately with the leaf springs, each gasket is provided with a round hole, the topmost gasket is provided with a threaded hole, the sliding bolt cooperates with the threaded hole, and a support block is fixedly installed on the lower side of the gasket, and the support block is attached to the coil connection plate.

[0010] Further, a long fixing rod is fixedly installed on the base, and the long fixing rod penetrates into the driver housing. The long fixing rod is used to fix the counterweight that does not participate in the counterweight.

[0011] Further, a short fixing rod is fixedly installed on the lower side of the coil connection plate. A first fixing hole is arranged on the short fixing rod, and a long bolt is fitted in the first fixing hole. The counterweight and the short fixing rod are fixed by the long bolt.

[0012] Further, a second fixing hole is arranged on the long fixing rod, and a short bolt is fitted in the second fixing hole. The counterweight and the long fixing rod are fixed by the short bolt.

[0013] Furthermore, a plurality of through holes are provided in the counterweight block. The short fixing rod and the long fixing rod are arranged in different through holes, and a gap is left between the inner wall of the through hole and the short fixing rod and the long fixing rod, so that the short fixing rod and the long fixing rod have a movable vibration space in the through hole.

[0014] Furthermore, the distance from the first fixing hole to the coil connecting plate is shorter than the distance from the second fixing hole to the coil connecting plate. When the counterweight block is fixed on the long fixing rod, there is a gap between the counterweight block fixed on the short fixing rod and the adjacent counterweight block fixed on the long fixing rod.

[0015] The beneficial effects of the present invention compared with the prior art are as follows:

[0016] (1) Through the technical solution of the present invention, the distance between the second iron core and the armature is adjusted by using the iron core adjusting bolt, which solves the problems that the distance cannot be adjusted after the driver is assembled, or the whole driver needs to be disassembled during adjustment, which affects the work efficiency, and the disassembly and assembly also affect the product quality. The structure of this case is simple, the elastic component between the connecting frame and the trough body in the traditional structure is cancelled, and then the amount of material input into the trough body per unit time has no influence on the conveying speed of the equipment, thus ensuring the consistency of the conveying speed of the equipment.

[0017] (2) Through the technical solution of the present invention, the position of the support locking member can be adjusted, so that the support positions at both ends of the elastic component change. When the required vibration amplitude is small, the two support locking members are relatively close to each other, so that the elastic component can quickly return to its original position after being attracted. If the two farthest segments of the elastic component are always fixed, then when the vibration amplitude is small, the rebound effect is difficult to control and not sensitive enough. The movable support locking member overcomes this defect.

[0018] (3) Through the technical solution of the present invention, when controlling the output power, the counterweight is also adjusted accordingly. The adjustable counterweight can better adapt to the material transmission, greatly improving the transmission performance to meet different requirements. And the counterweight is fixed through the first fixing hole and the second fixing hole, which can be achieved only by rotation without disassembly, greatly improving the efficiency and without removing the counterweight block. And through the gap, it can be ensured that the counterweight block not connected to the electromagnetic driver will not affect the work of other counterweight blocks.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0029] As Figure 1 , Figure 2 shown, an electromagnetic-driven feeder includes a base 21, the base 21 is fixed on the ground or other racks, a rubber block 18 is fixedly installed on the base 21, a total of four rubber blocks 18 are provided, a trough 19 is fixedly installed on the rubber block 18, a connecting frame 20 is fixedly installed at one end of the lower side of the trough 19, a bracket 31 is fixedly installed on the first side of the connecting frame 20, the bracket 31 supports the end of the trough 19, and an electromagnetic driver is fixedly installed on the second side of the connecting frame 20.

[0030] AsFigure 3 , Figure 4 As shown in Figure 4 , in this embodiment, the electromagnetic driver includes a driver housing 2. A connecting plate 13 is fixedly installed on the driver housing 2. A groove body connecting plate 1 is fixedly installed on the outer side of the connecting plate 13 and is fixed by a second fixing bolt 14. The groove body connecting plate 1 is fixedly connected to a connecting frame 20 by bolts. The outer side of the present invention refers to the end of the electromagnetic driver close to the groove body 19, and the upper side of the present invention refers to the side of the electromagnetic driver close to the groove body 19. An elastic component 3 is fixedly installed on the inner side of the connecting plate 13. Upper cushion blocks 12 and weight cushion blocks 11 are fixedly installed at both ends of the elastic component 3. The elastic component 3 is fixed to the inner side of the connecting plate 13 through the weight cushion blocks 11 and the upper cushion blocks 12. A coil connecting plate 4 is connected to the lower end of the weight cushion block 11. The connecting plate 13, the upper cushion block 12, the elastic component 3, and the weight cushion block 11 are sequentially penetrated and fixed by long connecting bolts. A plurality of weight blocks 5 are installed at the lower end of the coil connecting plate 4. A coil 6 is installed at the lower end of the middle position of the coil connecting plate 4. The weight blocks 5 are located on both sides of the coil 6.

[0031] In this embodiment, a first iron core 15 and a second iron core 16 are arranged in the coil 6. An armature 17 is fixedly installed in the middle part of the elastic component 3. After the coil 6 is energized, it attracts the armature 17. After the armature 17 is attracted, it abuts against the second iron core 16 and then returns to its original state. Repeating this process forms vibrations. A second iron core adjusting bolt 7 is installed at the bottom of the driver housing 2. The second iron core adjusting bolt 7 passes through the second iron core 16 from the outside of the driver housing 2 and is connected to the second iron core 16. Rotating the second iron core adjusting bolt 7 can control the distance between the second iron core 16 and the armature 17 and also change the distance between the first iron core 15 and the second iron core 16. The coil 6 is led out and energized through a cable 8. A support screw 9 is used to fix the coil 6 on the coil connecting plate 4. A first fixing bolt 10 is fixedly installed on the driver housing 2. The position of the first fixing bolt 10 corresponds to that of the weight block 5 to limit the weight block 5 to prevent the weight block 5 from directly falling off. Through the above technical solution, adjusting the distance between the second iron core 16 and the armature 17 by using the second iron core adjusting bolt 7 solves the problems that the driver is not allowed to be adjusted after assembly or that the entire driver needs to be disassembled during adjustment, which not only affects the work efficiency but also affects the product quality during disassembly and assembly. The structure of this case is simple. The elastic component 3 between the connecting frame 20 and the groove body 19 in the traditional structure is cancelled. Subsequently, the amount of material input into the groove body 19 per unit time has no impact on the conveying speed of the equipment, thus ensuring the consistency of the equipment conveying speed.

[0032] As Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, in this embodiment, the elastic component 3 includes a plurality of leaf springs, and each leaf spring is separated by spacers at both ends; a guide seat 28 is provided on the driver housing 2, a chute is provided at the middle position of the guide seat 28, and a sliding bolt 29 is slidably installed in the chute. Two support locking members 30 are slidably installed on the coil connection plate 4. The support locking member 30 includes a gasket 301 and a support block 302. The sliding bolt 29 cooperates with the support locking member 30 to lock both ends of the elastic component 3; a plurality of gaskets 301 and support blocks 302 are provided. The plurality of gaskets 301 are arranged alternately with the leaf springs to clamp each leaf spring. Each gasket 301 is provided with an ordinary round hole, and the uppermost gasket 301 is a threaded hole. The two sides of the support block 302 are provided with ordinary round holes. The support block 302 is located between the elastic component 3 and the coil connection plate 4, and the support block 302 is in contact with the coil connection plate 4. The sliding bolt 29 passes through the ordinary round holes of the gasket 301 and the support block 302 and cooperates with the threaded hole of the uppermost gasket 301. Rotate the sliding bolt 29 into the threaded hole of the uppermost gasket 301, and then make the uppermost gasket 301 close to the guide seat 28 to squeeze the other gaskets 301 and support blocks 302 for fixation. The sliding bolt 29 is stuck on the guide seat 28, that is, both ends of the elastic component 3 are fixed by the upper cushion block 12 and the counterweight cushion block 11. The support locking member 30 can slide to control the position. The support locking members 30 are strung together by the sliding bolt 29. After the position is adjusted, the sliding bolt 29 fixes the support locking member 30. At this time, the leaf springs in the elastic component 3 can only vibrate in the area between the two support locking members 30. Adjust the position of the support locking member 30 to change the support positions at both ends of the elastic component 3. When a smaller vibration amplitude is required, the distance between the two support locking members 30 is relatively close. In this way, it can be ensured that the elastic component 3 can quickly return to its original position after being attracted. If the two farthest ends of the elastic component 3 are always fixed, then when the vibration amplitude is small, the rebound effect is not easy to control and is not sensitive enough. The movable support locking member 30 overcomes this defect.

[0033] As Figure 7 , Figure 8As shown, in this embodiment, a long fixing rod 27 is fixedly installed on the base 21, and the long fixing rod 27 penetrates into the driver housing 2. The long fixing rod 27 is used to fix the counterweight block 5 that does not participate in the counterweight. A short fixing rod 23 is fixedly installed on the lower side of the coil connecting plate 4. The counterweight block 5 that participates in the counterweight is fixed on the short fixing rod 23. A first fixing hole 24 is provided on the short fixing rod 23, and a long bolt 22 is fitted in the first fixing hole 24. The counterweight block 5 and the short fixing rod 23 are fixed by the long bolt 22. A second fixing hole 26 is provided on the long fixing rod 27, and a short bolt 25 is fitted in the second fixing hole 26. The counterweight block 5 and the long fixing rod 27 are fixed by the short bolt 25.A plurality of through holes are provided in the counterweight block 5. The short fixing rod 23 and the long fixing rod 27 are arranged in the through holes. The inner diameter of the through holes is larger than the inner diameters of the short fixing rod 23 and the long fixing rod 27. A gap is left between the inner wall of the through hole and the short fixing rod 23 and the long fixing rod 27, so that the short fixing rod 23 and the long fixing rod 27 have a movable vibration space in the through hole; the distance from the first fixing hole 24 to the coil connecting plate 4 is shorter than the distance from the second fixing hole 26 to the coil connecting plate 4. When the counterweight block 5 is fixed on the long fixing rod 27, there is a gap between the counterweight block 5 fixed on the short fixing rod 23 and the counterweight block 5 fixed on the long fixing rod 27. The plurality of through holes in the counterweight block 5 are specifically provided with three through holes, and each through hole corresponds to a circular groove. The long fixing rod 27 is inserted into the middle through hole, and the short fixing rod 23 is inserted into the through holes on both sides. When using the counterweight block 5, the long bolt 22 is passed through the circular groove and fitted into the first fixing hole 24. Threaded fit is used here. If the counterweight needs to be reduced, some counterweight blocks 5 need to be removed. Then, it is necessary to remove them one by one from a position far from the trough body 19. The long bolt 22 is loosened. At this time, the counterweight block 5 will automatically separate from the fixed counterweight block 5 and slide down naturally. At this time, it is limited by the first fixing bolt 10 and will not separate too far, just making the second fixing hole 26 correspond to the circular groove on the middle through hole. At this time, the short bolt 25 is used to fix the counterweight block 5 and the long fixing rod 27. There is a distance between the counterweight block 5 fixed on the long fixing rod 27 and the counterweight block 5 fixed on the short fixing rod 23. At the same time, the internal size of the through groove is large, and when the counterweight block 5 connected to the electromagnetic driver vibrates, it will not affect the fixing of other counterweight blocks 5 on the long fixing rod 27. The long fixing rod 27 passes through the electromagnetic driver and is fixedly connected to the base 21. In other embodiments, it can also be connected to other frames or the ground as long as it can ensure stability and does not vibrate with the trough body 19. Holes are also provided at the position where the long fixing rod 27 passes through the driver housing 2. The hole size allows the long fixing rod 27 to have a vibration space. When controlling the output power, the counterweight will be adjusted accordingly. The adjustable counterweight can better adapt to material transmission, greatly improving the transmission performance to meet different requirements. And the counterweight is fixed through the first fixing hole 24 and the second fixing hole 26, which can be achieved only by rotation without disassembly, greatly improving the efficiency and eliminating the need to remove the counterweight block 5. And through the gap, it can be ensured that the counterweight blocks 5 not connected to the electromagnetic driver will not affect the operation of other counterweight blocks 5.

[0034] Working principle: Place the material in the trough body 19. Adjust the distance between the armature 17 and the second iron core 16 according to requirements. Rotate the iron core adjusting bolt 7 for adjustment. When rotating the iron core adjusting bolt 7, the end of the iron core adjusting bolt 7 cooperates with the second iron core 16. The movement of the iron core adjusting bolt 7 drives the movement of the second iron core 16. The iron core adjusting bolt 7 is threadedly engaged with the driver housing 2, which can fix the position, and finally also fixes the position of the second iron core 16. At the same time, loosen the support locking member 30 for adjustment as well. Move the sliding bolt 29 and the support locking member 30. When moving to the appropriate position, rotate the sliding bolt 29. The gasket 301 farthest from the coil connecting plate 4 is provided with a threaded hole, and the other gaskets 301 and the support block 302 are provided with ordinary round holes. The sliding bolt 29 passes through the ordinary round holes and cooperates with the threaded hole. Rotation drives the farthest gasket 301 to approach the coil connecting plate 4, and the support block 302 is in contact with the coil connecting plate 4, thereby performing extrusion. Finally, all the leaf springs are fixed, and at the same time, the sliding bolt 29 also tightly clamps the guide seat 28 for fixation.

[0035] Subsequently, the counterweight is adjusted according to the material weight. The counterweight block 5 is fixed to the short fixed rod 23 according to requirements. The short fixed rod 23 is fixedly connected to the coil connection plate 4 inside the electromagnetic driver. The unnecessary counterweight blocks 5 are fixed on the long fixed rod 27, and the long fixed rod 27 is connected to the outside. Then, power is supplied to perform vibration. Specifically, in this embodiment, a total of seven counterweight blocks 5 are provided. The counterweight block 5 farthest from the coil connection plate 4 is the first one, the fixing hole 1 24 farthest from the coil connection plate 4 is the first one, and the fixing hole 2 26 farthest from the coil connection plate 4 is the first one. If six counterweight blocks 5 are needed for counterweight, then the second to seventh counterweight blocks 5 are all fixed on the short fixed rod 23. The long bolt 22 passes through the circular groove of the counterweight block 5 and is screwed into the fixing hole 1 24 to fix the first counterweight block 5 on the long fixed rod 27. Since the distances from the fixing hole 2 26 and the fixing hole 1 24 to the coil connection plate 4 are different, but the circular grooves on the counterweight blocks 5 are on the same straight line. When the first counterweight block 5 is fixed in the first fixing hole 2 26 using the short bolt 25, there will be a gap between the first counterweight block 5 and the second counterweight block 5. The distance from the fixing hole 2 26 of the same layer to the coil connection plate 4 is greater than the distance from the fixing hole 1 24 to the coil connection plate 4. That is to say, for the same first counterweight block 5, it will fit with the second counterweight block 5 when fixed on the corresponding fixing hole 1 24, and there will be a gap between it and the second counterweight block 5 when fixed on the first fixing hole 2 26. If five counterweight blocks 5 are needed for counterweight, then the first counterweight block 5 and the second counterweight block 5 need to be fixed on the long fixed rod 27. In this way, the first counterweight block 5 and the second counterweight block 5 fit together, and there will be a gap between the second counterweight block 5 and the third counterweight block 5. When performing vibration feeding, the counterweight blocks 5 participating in the counterweight will vibrate, while the counterweight blocks 5 not participating in the counterweight fixed on the long fixed rod 27 do not vibrate. At this time, the gaps between the counterweight blocks 5 can ensure that the vibration is not affected. The gaps are left between the inner walls of the three through holes provided on the counterweight blocks 5 and the short fixed rod 23 and the long fixed rod 27, which can also ensure that the long fixed rod 27 and the non-vibrating counterweight blocks 5 are not affected by the vibration during vibration. All adjustments are made on the outside of the driver housing 2 without the need for disassembly and assembly, which greatly saves the time for adjustment.

[0036] In this invention patent, the distance between the second iron core 16 and the armature 17 is adjusted by the iron core adjusting bolt, so as to control the magnitude of the output power, and then change the driving force for the trough 19 to convey materials. It is simple, convenient and user-friendly. During the material conveying process, the equipment can be adjusted to facilitate finding the optimal conveying effect, greatly shortening the equipment adjustment time, and it is safe and reliable, avoiding repeated disassembly of the equipment and affecting the equipment consistency problem, eliminating the quality hidden danger caused by disassembly and adjustment of the equipment. In this invention, counterweights 5 are provided on both sides of the iron core. By designing the deformation amount of the elastic component 3, the weight ratio of all mechanical parts on one side of the counterweight 5 to the weight of the trough 19 and the materials is designed, so as to determine the designed material transmission performance: speed, amplitude, frequency, etc. Different amplitudes and frequencies can be used to suit the transmission of different materials, so as to achieve multi-purpose use of one machine, standardize the equipment, save costs, and ensure the stability and reliability of the equipment. The trough 19 of this invention is simply and ingeniously designed. The connecting frame 20 adopts a height adjusting rod with adjustable height or other types of adjusting methods, which is convenient for equipment installation and different use environments and requirements. In this invention, the elastic component 3 under the trough 19 is cancelled. Subsequently, the amount of materials input into the trough 19 per unit time has no influence on the conveying speed of the equipment, thus ensuring the consistency of the equipment conveying speed. The structure of this invention is ingeniously and simply designed. The driving force of the driver is directly transmitted to the trough 19. The amplitude of the trough 19 and the driving frequency can be adjusted to the optimal proportional relationship, so that the materials are conveyed at a high speed and smoothly, without skipping phenomenon.

[0037] The above embodiments only represent one or several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
