Detailed Implementation

[0023] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] The following is combined Figures 1 to 7 The present invention describes an electromagnetic vibration feeding device for preparing glass batches.

[0025] Example 1, as Figures 1 to 6 As shown, the electromagnetic vibration feeding device for preparing glass batch materials of the present invention includes a frame 1, a screen frame 2, a crushing plate 3, and a guide plate 4. A hopper 11 is fixed on the frame 1. The screen frame 2 is located below the hopper 11 and tilts from the upper left to the lower right. Lifting rings 21 are fixed on both the front and rear sides of the screen frame 2, with the lifting rings 21 located in the left half of the screen frame 2. The lifting rings 21 are connected to the hopper 11 via a first vibration damper 22. Two fixing rings 23 are provided on both the front and rear sides of the screen frame 2, located in the right half of the screen frame 2 and spaced apart along the tilting direction of the screen frame 2. The frame 1 has bolts 12 of equal number and corresponding to the number of fixing rings 23, extending vertically. The fixing rings 23 are fitted onto the corresponding bolts 12. The hopper 11 and the screen frame 2 are vertically connected.

[0026] The bottom of the screen frame 2 constitutes an inclined screen plate 24, the right half of the screen plate 24 is provided with a plurality of first screen holes 241 uniformly distributed, the first screen holes 241 are used for screening large particles and small particles in the glass raw material, the inside of the rack 1 is provided with an electromagnetic vibrator 5, the electromagnetic vibrator 5 is located on the left side of the screen frame 2, the electromagnetic vibrator 5 is fixed with a hanging ring 51 on the front and back sides, the hanging ring 51 is connected with the rack 1 through a second damper 52, the electromagnetic vibrator 5 is connected with the screen frame 2 and is used to drive the screen frame 2 to vibrate. The crushing plate 3 extends along the front and back directions and is close to the bottom of the screen plate 24, an included angle is formed between the plate surface of the crushing plate 3 and the plate surface of the screen plate 24, and the included angle is an acute angle. The crushing plate 3 is fixed with a support shaft 31 at four corners, the support shaft 31 extends along the front and back directions, the four support shafts 31 correspond to the four fixed rings 23 one by one, the support shaft 31 penetrates through the screen frame 2 and is fixedly connected with the corresponding fixed ring 23. The crushing plate 3 and the screen plate 24 form a squeezing gap 32, it can be understood that the squeezing gap 32 gradually narrows from the upper left to the lower right, the squeezing gap 32 is used for passing the granular glass raw material, and the crushing plate 3 is sleeved with a belt mechanism 6 on the outer circumferential side, and the belt mechanism 6 can circularly move.

[0027] The guide plate 4 is located below the screen plate 24, the plate surface of the guide plate 4 is parallel to the plate surface of the screen plate 24, the front and back sides of the guide plate 4 are fixedly connected with the screen frame 2, the left end of the guide plate 4 is fixedly connected with the screen plate 24, and the guide plate 4 can receive the small particle raw material screened by the first screen hole 241. The screen frame 2 is rotatably provided with an impeller 7 adjacent to the bottom end of the guide plate 4 and located below the guide plate 4, and the impeller 7 is connected with the belt mechanism 6 through a transmission assembly 8.

[0028] Initially, the glass raw material is uniformly and continuously fed into the screen frame 2 through the hopper 11, and the electromagnetic vibrator 5 is started at the same time. Under the action of vibration and gravity, the glass raw material flows downward along the screen plate 24, when passing through the first screen hole 241, the large particles and small particles in the glass raw material are separated, the small particle raw material passes through the first screen hole 241 and falls on the guide plate 4, and then flows downward along the guide plate 4. The large particle raw material continues to flow along the screen plate 24 to the squeezing gap 32. When the small particle raw material flows out of the guide plate 4, it can fall on the impeller 7 under the action of gravity, thereby driving the impeller 7 to rotate, and the impeller 7 drives the belt mechanism 6 to circularly move through the transmission assembly 8. At the same time, the large particle raw material flows into the squeezing gap 32, and the screen plate 24 is squeezed with the crushing plate 3 under the action of vibration force, thereby crushing the large particle raw material. The gradually narrowing squeezing gap 32 can realize the gradual extrusion of the large particle raw material, and gradually reduce the particle size of the large particle raw material. At the same time, the circular movement of the belt mechanism 6 can help the glass raw material in the squeezing gap 32 to move, avoid the glass raw material from being stuck in the squeezing gap 32, and ensure the reliable operation of the whole device.

[0029] Therefore, the electromagnetic vibratory feeding device for glass batch preparation of the present invention can integrate the feeding, screening and crushing of glass raw materials into one step, reducing the steps of the assembly line operation and thus saving time and labor. In addition, the cyclical movement of the belt mechanism 6 ensures that large particles of raw materials can flow smoothly while being crushed, avoiding blockage.

[0030] The impeller 7 includes a shaft 71 and blades 72. The shaft 71 extends in the front-to-back direction and is rotatably mounted on the screen frame 2 at both ends. There are multiple blades 72, which are evenly distributed around the circumference of the shaft 71. The blades 72 extend in the front-to-back direction and are arc-shaped. The blades 72 are fixedly connected to the shaft 71.

[0031] The belt mechanism 6 includes bushings 61 and annular belts 62. The number of bushings 61 is equal to the number of support shafts 31 and they correspond one-to-one. The bushings 61 are rotatably fitted onto the corresponding support shafts 31. The bushings 61 pass through the screen frame 2 and are rotatably connected to the screen frame 2. The annular belt 62 is fitted onto four bushings 61 and covers the crushing plate 3. Understandably, the annular belt 62 extends in the front-to-back direction. Two bushings 61 opposite each other along the inclined direction of the crushing plate 3 tension the annular belt 62. Understandably, one of the bushings 61 is connected to the axle 71 through the transmission assembly 8.

[0032] When small particles of raw material flow out of the guide plate 4, they fall onto the concave arc surface of the blade 72, thereby driving the blade 72 to rotate. The blade 72 drives the wheel shaft 71 to rotate. The wheel shaft 71 drives one of the bushings 61 to rotate through the transmission assembly 8. The bushing 61 drives the remaining bushings 61 to rotate synchronously through the annular belt 62. At the same time, the annular belt 62 performs cyclical motion.

[0033] The arc-shaped design of blade 72 allows it to hold small particles of raw material, reducing the loss of small particles and delaying the separation time between small particles and blade 72. This allows the small particles to act on blade 72 for a longer period of time, thus making full use of the gravity of the small particles.

[0034] A separator ring 621 is fitted on the outer surface of the annular belt 62. The separator ring 621 is fixedly connected to the annular belt 62. There are multiple separator rings 621, which are evenly distributed along the front and back direction. Both the separator ring 621 and the annular belt 62 can be made of rubber.

[0035] When large glass raw materials pass through the extrusion gap 32, some of the raw materials may be damp, making them easily flattened by the sieve plate 24 and the crushing plate 3. The flattened raw materials are not separated, and their particle size is not reduced. At this time, this part of the raw materials can be squeezed and contacted by the separating ring 621 under the vibration of the sieve plate 24. The separating ring 621 separates the flattened raw materials, thereby reducing the particle size of the raw materials.

[0036] To further process the glass raw material after extrusion gap 32, the present invention also provides Embodiment 2.

[0037] Example 2, based on Example 1, continues to refer to... Figures 2 to 7 The electromagnetic vibratory feeding device for glass batch preparation also includes an extrusion frame 9 and a drive column 93. The bottom end of the sieve plate 24 is provided with multiple second sieve holes 242, which are evenly distributed. Understandably, the second sieve holes 242 are located below the first sieve holes 241. The second sieve holes 242 are vertically opposite to the impeller 7. The extrusion frame 9 is located near the bottom end of the sieve plate 24 and extends in the front-to-back direction. The extrusion frame 9 is fixedly connected to the sieve frame 2 and is used to receive granular raw materials sliding off the sieve plate 24.

[0038] The bottom of the extrusion frame 9 has multiple recessed grooves evenly distributed along the front-to-back direction. Each recessed groove is a conical groove 91 with its tip pointing downwards, and the specific shape of the conical groove 91 is a square pyramid. The wall of the extrusion frame 9 that forms the conical groove 91 has a material passage hole 92, which connects the bottom end of the conical groove 91 to the outside. A drive column 93 extends along the front-to-back direction and is located inside the extrusion frame 9. Both ends of the drive column 93 are rotatably mounted on the extrusion frame 9. The drive column 93 has a magnetic part 931. Specifically, the cylinder of the drive column 93 is cut with a virtual axial section, and the cylinder is divided into two halves. Either half can serve as the magnetic part 931 of the drive column 93. This magnetic part 931 is made of magnetic material and has magnetic force. A support plate 94 is fixed inside the extrusion frame 9, located between the drive column 93 and the conical groove 91. An extrusion head 95 is provided on the side of the support plate 94 facing the conical groove 91. The number of extrusion heads 95 is equal to the number of material passage holes 92, and they correspond one-to-one. The extrusion heads 95 and the surface of the support plate 94 facing the conical groove 91 are connected by a spring 96. A guide rope 97 is provided inside the spring 96, and both ends of the guide rope 97 are fixedly connected to the extrusion head 95 and the support plate 94, respectively. The shape of the extrusion head 95 can be spherical or square, etc., and this embodiment is not limited to this. Its material can be magnetically attracted iron or steel, etc. Under normal conditions, the extrusion head 95 is fitted into the corresponding material passage hole 92, and the drive column 93 is connected to the impeller 7 through a transmission assembly 8.

[0039] After passing through the extrusion gap 32, most of the large raw material particles are crushed into smaller particles. These glass particles then flow to the bottom of the sieve plate 24, where the smaller particles pass through the second sieve hole 242 and fall onto the impeller 7, thus promoting the rotation of the impeller 7. Some incompletely crushed large particles cannot pass through the second sieve hole 242 and continue to flow downwards, sliding off the sieve plate 24. These larger particles then flow into the extrusion frame 9, are distributed into the various conical grooves 91, and then flow towards the feed hole 92. At this point, the particle size of these large particles is usually slightly larger than the diameter of the feed hole 92, making it difficult for them to pass through.

[0040] Meanwhile, the rotating impeller 7 also drives the drive column 93 to rotate via the transmission assembly 8, and the orientation of the magnetic part 931 in the drive column 93 continuously changes. When the magnetic part 931 of the drive column 93 faces the extrusion head 95, the magnetic part 931 can pull the extrusion head 95 out of the material passage 92. When the magnetic part 931 of the drive column 93 faces away from the extrusion head 95, the attraction of the magnetic part 931 to the extrusion head 95 weakens, and the extrusion head 95 can be inserted into the material passage 92 under the elastic force of the spring 96, and hammer the large particles of raw material in the material passage 92, breaking them down. This achieves secondary processing of the large particles of raw material, and the particle size of the processed large particles of raw material is smaller, which usually meets the requirements. Subsequently, the processed glass raw material falls from the material passage 92 under the action of hammering force and gravity, and enters the next stage.

[0041] The transmission assembly 8 includes pulleys 81, a transmission belt 82, and a second gear 83. There are three pulleys 81, all located on the front side of the screen frame 2. Two of the pulleys 81 are coaxially connected to the axle 71 and the drive column 93, respectively. A support plate 25 is provided on the front side of the screen frame 2, and the support plate 25 is fixedly connected to two fixed rings 23 on the same side. A rotating shaft is rotatably mounted on the support plate 25, with its axis extending in the front-rear direction. Another pulley 81 is fitted onto the rotating shaft, and a first gear 84 is also fitted onto the rotating shaft. Understandably, the first gear 84 is coaxial with the aforementioned pulley 81. The transmission belt 82 is annular and fitted onto the three pulleys 81. The second gear 83 is coaxially connected to one of the bushings 61 and meshes with the first gear 84.

[0042] When the axle 71 drives the pulley 81 to rotate, the transmission belt 82 drives the other two pulleys 81 to rotate, thereby causing the drive column 93 to rotate. Simultaneously, the first gear 84 rotates synchronously with the pulley 81, and then drives the bushing 61 to rotate via the second gear 83, thus realizing the cyclic motion of the annular belt 62. When the screen frame 2 vibrates, the transmission belt 82, utilizing its flexibility, can contract inwards or expand outwards, achieving a close contact with the pulley 81 and ensuring effective transmission. Both the first gear 84 and the second gear 83 are indirectly mounted on the frame 1, preventing the vibration of the screen frame 2 from affecting the bushing 61.
