Description

Technical Field

[0001] The invention relates to the technical field of feeders, and in particular to a novel 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 a new 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] The lower end of the coil connecting plate is fixed with a counterweight and a coil; an iron core 1 and an iron core 2 are arranged inside the coil, and an armature is fixedly installed in the middle part of the elastic component. When the coil is energized, the armature is attracted to contact the iron core 2. An iron core adjusting bolt is installed at the bottom of the driver housing, and the iron core adjusting bolt passes through the iron core 1 and is connected to the armature. Rotating the iron core adjusting bolt can control the distance between the iron core 2 and the armature. Through the technical solution of the present invention, the distance between the iron core 2 and the armature is adjusted by using the iron core adjusting bolt, which solves the problem that the driver is not allowed to be adjusted after assembly or the entire driver needs to be disassembled for adjustment, which affects the work efficiency and the disassembly and assembly also affects the product quality. The present case has a simple structure and eliminates the elastic component between the connecting frame and the tank body in the traditional structure. Then, the amount of material input into the tank body per unit time has no effect on the equipment conveying speed, thereby ensuring the consistency of the equipment conveying speed.

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

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

[0008] Furthermore, a guide seat is provided on the driver housing, a slide groove is provided in the middle position of the guide seat, a sliding bolt is slidably installed in the slide groove, and two supporting locking members are slidably installed on the coil connecting plate, which are respectively located on both sides of the coil, and the supporting locking members are located between the elastic component and the coil connecting plate, and the sliding bolt cooperates with the supporting locking member to fix the elastic component.

[0009] Furthermore, the support locking member includes multiple gaskets, which are staggered with leaf springs, each gasket is provided with a round hole, the top gasket is provided with a threaded hole, the sliding bolts cooperate with the threaded holes, a support block is fixed on the lower side of the gasket, and the support block is fitted with the coil connecting plate.

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

[0011] Furthermore, a short fixing rod is fixedly mounted on the lower side of the coil connection plate, a fixing hole 1 is provided on the short fixing rod, a long bolt is fitted in the fixing hole 1, and the counterweight block and the short fixing rod are fixed by the long bolt.

[0012] Furthermore, a second fixing hole is provided on the long fixing rod, and a short bolt is fitted in the second fixing hole to fix the counterweight block and the long fixing rod through the short bolt.

[0013] Furthermore, a plurality of through holes are arranged in the counterweight block, and the short fixed rod and the long fixed rod are arranged in different through holes, and gaps are left between the inner walls of the through holes and the short fixed rod and the long fixed rod, so that the short fixed rod and the long fixed rod have active vibration space in the through holes.

[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 is fixed on the long fixing rod, there is a gap between the counterweight fixed on the short fixing rod and the adjacent counterweight fixed on the long fixing rod.

[0015] The beneficial effects of the present invention compared with the prior art are: (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 adjustment bolt, which solves the problem that the driver is not allowed to be adjusted after assembly or the entire driver needs to be disassembled for adjustment, which affects the work efficiency, and the disassembly and assembly also affects the product quality. The present case has a simple structure and eliminates the elastic component between the connecting frame and the tank body in the traditional structure. Then, the amount of material input into the tank body per unit time has no effect on the equipment conveying speed, thereby ensuring the consistency of the equipment conveying speed.

[0016] (2) Through the technical solution of the present invention, the position of the support locking member can be adjusted, so that the support position at both ends of the elastic component can be changed. When the amplitude of vibration required is small, the two support locking members are relatively close to each other, which can ensure that the elastic component quickly returns to its original position after being attracted. If the two farthest sections of the elastic component are always fixed, then the rebound effect is difficult to control and not sensitive enough when the vibration amplitude is small. The movable support locking member overcomes this defect.

[0017] (3) Through the technical solution of the present invention, when controlling the output power, the counterweight will also be adjusted accordingly. The adjustable counterweight can be more adaptable to material transmission and greatly improve the transmission performance to meet different needs. The counterweight is fixed through fixing hole 1 and fixing hole 2. It can be achieved by rotation only and does not need to be disassembled, which greatly improves the efficiency. There is no need to remove the counterweight block, and the gap can ensure that the counterweight block not connected to the electromagnetic drive will not affect the work of other counterweight blocks.

DETAILED DESCRIPTION

[0027] The following will be combined with the accompanying drawings in 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 belong to the protection scope of the present invention.

[0028] like Figure 1 , Figure 2 As shown, a new type of electromagnetic driven feeder includes a base 21, which is fixed on the ground or other frames. A rubber block 18 is fixed on the base 21. There are four rubber blocks 18 in total. A trough body 19 is fixed on the rubber block 18. A connecting frame 20 is fixed on one end of the lower side of the trough body 19. A bracket 31 is fixed on the first side of the connecting frame 20. The bracket 31 supports the end of the trough body 19. An electromagnetic driver is fixed on the second side of the connecting frame 20.

[0029] like Figure 3 , Figure 4 As shown, in this embodiment, the electromagnetic driver includes a driver housing 2, on which a connecting plate 13 is fixedly mounted, a slot body connecting plate 1 is fixedly mounted on the outer side of the connecting plate 13, and the slot body connecting plate 1 is fixedly mounted by fixing bolts 14, the slot body connecting plate 1 is fixedly connected to the connecting frame 20 by bolts, the outer side of the present invention refers to the end of the electromagnetic driver close to the slot body 19, the upper side of the present invention refers to the side of the electromagnetic driver close to the slot body 19, the inner side of the connecting plate 13 is fixedly mounted with an elastic component 3, the two ends of the elastic component 3 are fixedly mounted with an upper pad 12 and a counterweight pad 11, the elastic component 3 is fixed to the inner side of the connecting plate 13 by the counterweight pad 11 and the upper pad 12, the lower end of the counterweight pad 11 is connected to a coil connecting plate 4, the connecting plate 13, the upper pad 12, the elastic component 3, and the counterweight pad 11 are successively penetrated and fixed by long connecting bolts, a plurality of counterweight blocks 5 are mounted on the lower end of the coil connecting plate 4, a coil 6 is mounted on the lower end of the middle position of the coil connecting plate 4, and the counterweight blocks 5 are located on both sides of the coil 6.

[0030] In this embodiment, an iron core 15 and an iron core 2 16 are provided in the coil 6, and an armature 17 is fixedly installed in the middle part of the elastic component 3. When the coil 6 is energized, the armature 17 is attracted. After the armature 17 is attracted, it abuts against the iron core 2 16 and then returns to its original state, and this is repeated to form vibration. An iron core adjusting bolt 7 is installed at the bottom of the driver housing 2. The iron core adjusting bolt 7 passes through the iron core 2 16 from the outside of the driver housing 2 and is connected to the iron core 2 16. Rotating the iron core adjusting bolt 7 can control the distance between the iron core 2 16 and the armature 17, and also change the distance between the iron core 15 and the iron core 2 16. The coil 6 is energized through the cable 8, and the coil 6 is fixed to the coil connecting plate 4 using the support screw 9. A fixing bolt 10 is fixedly installed on the driver housing 2. The position of the fixing bolt 10 corresponds to the counterweight 5, and the counterweight 5 is limited to prevent the counterweight 5 from falling off directly. Through the above technical solution, the distance between the core 2 16 and the armature 17 is adjusted by using the core adjusting bolt 7, which solves the problem that the driver is not allowed to be adjusted after assembly or the entire driver needs to be disassembled for adjustment, which affects the work efficiency and the disassembly and assembly also affects the product quality. The present case has a simple structure and eliminates the elastic component 3 between the connecting frame 20 and the tank body 19 in the traditional structure. Then, the amount of material input into the tank body 19 per unit time has no effect on the equipment conveying speed, thereby ensuring the consistency of the equipment conveying speed.

[0031] like Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, in this embodiment, the elastic component 3 includes a plurality of leaf springs, each of which is separated by partitions at both ends; a guide seat 28 is provided on the driver housing 2, a slide groove is provided in the middle position of the guide seat 28, a sliding bolt 29 is slidably installed in the slide groove, and two supporting locking members 30 are slidably installed on the coil connecting plate 4, and the supporting locking members 30 include a gasket 301 and a supporting block 302. The sliding bolt 29 cooperates with the support locking piece 30 to lock the two ends of the elastic component 3; a plurality of gaskets 301 and support blocks 302 are provided, and a plurality of gaskets 301 are arranged alternately with the leaf springs to clamp each leaf spring, and each gasket 301 is provided with an ordinary round hole, and the gasket 301 at the upper end is a threaded hole, and ordinary round holes are provided on both sides of the support block 302, and the support block 302 is located between the elastic component 3 and the coil connecting plate 4, and the support block 302 is fitted with the coil connecting plate 4, and 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 upper end gasket 301, and the rotating sliding bolt 29 enters the threaded hole of the upper end gasket 301, and then the upper end gasket 301 is close to the guide seat 28 to squeeze the other gaskets 301 and the support block 302 for fixing, and the sliding bolt 29 is stuck in the guide seat 2 8, that is, the two ends of the elastic component 3 are fixed by the upper pad 12 and the counterweight pad 11, and the support locking piece 30 can slide to control the position. The support locking piece 30 is strung together by the sliding bolt 29. After the position is adjusted, the sliding bolt 29 stipulates the support locking piece 30. At this time, the leaf spring vibration in the elastic component 3 can only vibrate the area between the two support locking pieces 30. The position of the support locking piece 30 is adjusted to change the support position of the two ends of the elastic component 3. When the vibration amplitude is small, the two support locking pieces 30 are close to each other. This can ensure that the elastic component 3 quickly returns to its original position after being attracted. If the two farthest ends of the elastic component 3 are always fixed, then the rebound effect is not easy to control and is not sensitive enough when the vibration amplitude is small. The movable support locking piece 30 overcomes this defect.

[0032] like Figure 7 , Figure 8As shown, in this embodiment, a long fixing rod 27 is fixedly mounted 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 5 that does not participate in the counterweight. A short fixing rod 23 is fixedly mounted on the lower side of the coil connection plate 4, and the counterweight 5 that participates in the counterweight is fixed on the short fixing rod 23. The short fixing rod 23 is provided with a fixing hole 1 24, and a long bolt 22 is matched in the fixing hole 1 24, and the counterweight 5 and the short fixing rod 23 are fixed by the long bolt 22. A fixing hole 26 is provided on the long fixing rod 27, and a short bolt 25 is matched in the fixing hole 26, and the counterweight 5 and the long fixing rod 27 are fixed by the short bolt 25.A plurality of through holes are arranged in the counterweight 5, and the short fixing rod 23 and the long fixing rod 27 are arranged in the through holes. The inner diameter of the through hole is larger than the inner diameter 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 active vibration space in the through hole; the distance from the fixing hole 1 24 to the coil connecting plate 4 is shorter than the distance from the fixing hole 26 to the coil connecting plate 4. When the counterweight 5 is fixed on the long fixing rod 27, there is a gap between the counterweight 5 fixed on the short fixing rod 23 and the counterweight 5 fixed on the long fixing rod 27. The multiple through holes in the counterweight block 5 are specifically provided with three through holes, 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 the counterweight block 5 is used, the long bolt 22 is passed through the circular groove and matched into the fixing hole 24. Threaded matching is used here. If it is necessary to reduce the counterweight, some counterweight blocks 5 need to be removed. In this case, they need to be removed one by one from a position away from the slot body 19, and 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 fixing bolt 10 and does not The second fixing hole 26 will be separated too far, just making the 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 5 and the long fixing rod 27. There is a distance between the counterweight 5 fixed on the long fixing rod 27 and the counterweight 5 fixed on the short fixing rod 23. At the same time, the internal size of the through groove is large. When the counterweight 5 connected to the electromagnetic drive vibrates, it will not affect the other counterweights 5 fixed on the long fixing rod 27. The long fixing rod 27 passes through the electromagnetic drive and is fixedly connected to the base 21. In other embodiments, it can also be connected to other racks or the ground, as long as it can ensure stability without contacting the slot body 1. 9 can be vibrated together, and a hole is also set at the position where the long fixing rod 27 passes through the driver housing 2. The size of the hole allows the long fixing rod 27 to have space for vibration. When controlling the output power, the counterweight will also be adjusted accordingly. The adjustable counterweight can be more suitable for material transmission, greatly improving the transmission performance to meet different needs, and the counterweight is fixed through the fixing hole 1 24 and the fixing hole 2 26, which can be achieved by rotation only, and does not need to be disassembled, which greatly improves the efficiency, and there is no need to remove the counterweight block 5, and the gap can ensure that the counterweight block 5 not connected to the electromagnetic drive will not affect the work of other counterweight blocks 5.

[0033] Working principle: put the material in the trough 19, adjust the distance between the armature 17 and the second core 16 as needed, rotate the core adjusting bolt 7 to adjust, rotate the core adjusting bolt 7, the end of the core adjusting bolt 7 cooperates with the second core 16, the core adjusting bolt 7 moves to drive the second core 16 to move, the core adjusting bolt 7 and the driver housing 2 are threaded to fix the position, and finally the position of the second core 16 is fixed, and at the same time, loosen the support locking piece 30 to adjust, move the sliding bolt 29 and The support locking piece 30, when moved to the appropriate position, rotates the sliding bolt 29, and a threaded hole is set on the gasket 301 farthest from the coil connecting plate 4, and ordinary round holes are set on the other gaskets 301 and the support block 302. The sliding bolt 29 passes through the ordinary round hole and cooperates with the threaded hole, and rotates to drive the farthest gasket 301 close to the coil connecting plate 4, and the support block 302 fits with the coil connecting plate 4, thereby squeezing, and finally fixing all the leaf springs, and at the same time, the sliding bolt 29 also tightly clamps the guide seat 28 to fix it.

[0034] Then, the counterweight is adjusted according to the weight of the material, and the counterweight 5 is fixed to the short fixing rod 23 according to the demand. The short fixing rod 23 is fixedly connected to the coil connecting plate 4 inside the electromagnetic driver. The unnecessary counterweight 5 is fixed to the long fixing rod 27, and the long fixing rod 27 is connected to the outside and powered on for vibration. Specifically, in the present embodiment, a total of seven counterweights 5 are provided, and the counterweight 5 farthest from the coil connecting plate 4 is the first, the fixing hole 24 farthest from the coil connecting plate 4 is the first, and the fixing hole 22 farthest from the coil connecting plate 4 is the second. 6 is the first one. If six counterweights 5 are needed for counterweighting, then the second to seventh counterweights 5 are all fixed on the short fixing rod 23, and the long bolt 22 passes through the circular groove of the counterweight 5 and is screwed into the fixing hole 1 24 to fix the first counterweight 5 on the long fixing rod 27. Since the distances from the fixing hole 26 to the coil connecting plate 4 are different from the fixing hole 1 24, but the circular grooves on the counterweight 5 are on the same straight line, when the short bolt 25 is used to fix the first counterweight 5 in the first fixing hole 26, the first counterweight 5 and the second There will be a gap between the counterweights 5, and the distance from the second fixing hole 26 to the coil connecting plate 4 on the same layer is greater than the distance from the first fixing hole 24 to the coil connecting plate 4, that is to say, if it is the first counterweight 5, it will fit with the second counterweight 5 when fixed on the corresponding fixing hole 1 24, and if it is fixed on the first fixing hole 26, there will be a gap between it and the second counterweight 5. If five counterweights 5 are needed for counterweighting, then the first counterweight 5 and the second counterweight 5 need to be fixed on the long fixing rod 27, so that the first counterweight 5 and the first When two counterweights 5 are fitted, there will be a gap between the second counterweight 5 and the third counterweight 5. When vibrating and feeding, the counterweight 5 participating in the counterweight will vibrate, while the counterweight 5 not participating in the counterweight is fixed on the long fixed rod 27 and does not vibrate. At this time, the gap between the counterweights 5 can meet the requirement that the vibration is not affected, and the gap between the inner wall of the three through holes set on the counterweight 5 and the short fixed rod 23 and the long fixed rod 27 can also meet the requirement that the long fixed rod 27 and the counterweight 5 not participating in the vibration will not be affected by the vibration during vibration. All adjustments are made on the outside of the driver housing 2, and no disassembly is required, which greatly saves the time used for adjustment.

[0035] The invention patent adjusts the distance between the core 2 16 and the armature 17 by the core adjusting bolt 7, thereby controlling the output power to change the driving force of the trough 19 to transport the material. It is simple, convenient, and convenient for users to use. During the material transportation process, the equipment can be adjusted to facilitate finding the optimal transportation effect, greatly shortening the equipment adjustment time, and is safe and reliable, avoiding repeated disassembly of the equipment, affecting the consistency of the equipment, and eliminating the quality risks caused by the disassembly and adjustment of the equipment. The invention is provided with a counterweight 5 on both sides of the core. By designing the deformation of the elastic component 3, the weight ratio of all mechanical parts on one side of the counterweight 5 to the trough 19 and the material is designed, so as to determine the design of the material transmission performance: speed, amplitude, frequency, etc. Different amplitudes and different frequencies can be used to suit the transmission of different materials, so as to achieve one machine for multiple uses, standardize the equipment, save costs, and ensure the stability and reliability of the equipment. The trough 19 of the invention is simple and ingenious in design, and the connecting frame 20 adopts an adjustable height adjustment rod or other types of adjustment methods, which is convenient for equipment installation and different use environments and requirements. The present invention eliminates the elastic component 3 under the trough 19, and then the amount of material input into the trough 19 per unit time has no effect on the equipment conveying speed, thereby ensuring the consistency of the equipment conveying speed. The present invention has an ingenious and simple structural design, the driver driving force is directly transmitted to the trough 19, and the amplitude of the trough 19 and the driving frequency can be adjusted to an optimal proportional relationship, so that the material conveying speed is fast and the material conveying is stable without material jumping.

[0036] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
