Description

Technical Field

[0001] This invention relates to the field of casting technology, and specifically to a casting processing feeding mechanism and method. Background Technology

[0002] Cast metal refers to the metallic material used for casting in casting production. It is an alloy composed of a metallic element as the main component and other metallic or non-metallic elements added. It is conventionally called a casting alloy. In the traditional aluminum casting process, solid raw materials and liquid raw materials are generally mixed and then sent into the casting furnace for casting.

[0003] However, the existing solid raw materials are relatively large in size, and the contact area between solid and liquid raw materials is small, which is not conducive to the melting of solid raw materials and results in low casting efficiency. At the same time, in order to improve the purity of castings, impurities on the raw materials are usually cleaned. Usually, tools are used manually to clean the impurities and dust on the outside of the aluminum raw materials to maintain the cleanliness of the aluminum parts. However, manual cleaning is inefficient and may even cause injury to personnel. Moreover, the impurities and dust that are cleaned fall directly to the ground, making it difficult to clean the dust later.

[0004] Therefore, the present invention provides a casting processing feeding mechanism and method to solve the above problems. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the prior art, the present invention provides a casting processing feeding mechanism and method, which effectively solves the problems of large solid raw material size, which is not conducive to the melting of solid raw materials and low efficiency when manually using tools to clean impurities and dust on the outside of aluminum raw materials.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A casting processing feeding mechanism includes a support frame, a processing cylinder fixedly mounted on the support frame, a fixing ring fixedly mounted inside the processing cylinder, multiple screening boxes evenly rotatably mounted on the inner wall of the fixing ring, a filter screen mounted on the upper end of each screening box, a drive motor mounted on the top end of the processing cylinder, a positioning shaft extending into the processing cylinder fixedly mounted on the lower end of the drive motor, multiple stirring rods mounted on the positioning shaft, a drive device located below the fixing ring inside the processing cylinder, a feeding rack inside the support frame, a conveyor belt at the top end of the feeding rack, and a feeding port at the top end of the processing cylinder.

[0008] Preferably, the driving device includes a pull ring, which is slidably mounted on the inner wall of the processing cylinder. An upper fixing block is fixedly mounted on the bottom of each screening box, and lower fixing blocks are evenly fixedly mounted on the pull ring. A linkage rod connects each upper fixing block and its corresponding lower fixing block.

[0009] Preferably, a receiving hopper located below the pull ring is fixedly installed inside the processing cylinder, a crushing cylinder is fixedly installed at the bottom of the receiving hopper, a positioning rod is fixedly installed on the crushing cylinder, a drive shaft is rotatably installed on the positioning rod, a plurality of crushing blades are evenly fixedly installed on the drive shaft, and a mesh is provided at the bottom of the crushing cylinder.

[0010] Preferably, a collection box is fixedly installed on the bottom of each screening box, a discharge port is opened at the lower end of each collection box, a receiving box is rotatably installed at the inner end of each discharge port, and a discharge device is provided on the processing cylinder below each receiving box.

[0011] Preferably, a positioning block and a stabilizing block are fixedly installed at the outer end of the processing cylinder, a linkage shaft is installed between the positioning block and the stabilizing block, a first sprocket set is installed between the linkage shaft and the positioning shaft, and a second sprocket set is installed between the linkage shaft and the drive shaft.

[0012] Preferably, a mounting block is fixedly installed on the outer end of the crushing cylinder, a gear disk is rotatably installed on the mounting block, a discharge hole is opened on the gear disk, a linkage gear meshing with the gear disk is fixedly installed on the linkage shaft, and a feeding hopper is fixedly installed on the bottom end of the processing cylinder.

[0013] Preferably, the discharge device includes a discharge box, and a discharge box located below each receiving box is fixedly installed on the processing cylinder. A diagonal rod is fixedly installed on the inner end of each discharge box, and a baffle is fixedly installed on each diagonal rod. A rotating gear is fixedly installed on the shaft of each receiving box, and a drive rack that meshes with the rotating gear is slidably installed on each receiving box. A pressure spring is provided on each drive rack.

[0014] Preferably, a discharge box is fixedly installed at the outer end of each discharge box, and a collection box located below each discharge box is fixedly installed at the outer end of the processing cylinder.

[0015] Preferably, the processing cylinder has a vertical sliding hole, and a pull block located inside the sliding hole is fixedly installed on the pull ring, and the pull block is provided with a telescopic rod.

[0016] A method for feeding a casting machining mechanism includes the following steps:

[0017] Step 1: Personnel place the aluminum parts onto the top surface of the four filter screens through the feeding port, turn on the power, and the controller starts the drive motor.

[0018] Step 2: The positioning shaft, carrying multiple stirring rods, stirs the aluminum parts on the four filter screens, and impurities and dust fall into the impurity chamber through the holes in the filter screens.

[0019] Step 3: The telescopic rod slides down along the sliding hole with the pull block, and the pull ring moves with the four linkage rods. Each linkage rod swings down with the inner end of the corresponding screening box, and the aluminum parts slide down onto the receiving hopper through the gap below.

[0020] Step 4: The drive rack contacts the corresponding baffle. Due to the obstruction of the baffle, the drive rack slides upward along the cavity of the collecting box and meshes with the rotating gear to rotate. The pressure spring is gradually compressed, and the rotating gear carries the receiving box to swing downward at an inclined angle. The impurities inside each screening box slide down the inclined surface of the impurity cavity into the receiving box.

[0021] Step 5: Impurities inside the receiving box will slide into the discharge box below, and then the impurities will slide into the collection box through the discharge box.

[0022] Step 6: The drive shaft drives multiple crushing blades to rotate rapidly. The crushed aluminum pieces fall through the screen onto the top surface of the gear disc. When the discharge hole coincides with the bottom port of the crushing cylinder, the crushed aluminum pieces fall quickly into the discharge port of the hopper through the discharge hole, and the aluminum pieces finally fall onto the conveyor belt.

[0023] Step 7: The conveyor motor drives two rotating rollers and the conveyor belt to rotate, and the conveyor belt transports the aluminum parts to the melting area for melting and casting.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. The stirring rod agitates the aluminum parts, causing impurities and dust adhering to them to fall off. These impurities are collected in the impurity chamber, accelerating the removal of impurities from the aluminum parts. At the same time, the conveyor belt transports the aluminum parts to the melting area for melting and casting, reducing manual labor and preventing injury to personnel, thus improving work efficiency.

[0026] 2. The drive shaft drives multiple crushing blades to rotate rapidly. The crushing blades can break the aluminum parts into pieces. The broken aluminum pieces fall through the screen. Because the broken aluminum pieces or blocks are small in size, they can accelerate the melting speed of the aluminum parts and make the aluminum parts melt more thoroughly, thus improving the casting efficiency.

[0027] 3. Because the discharge hole intermittently coincides with the bottom port of the crushing cylinder, intermittent quantitative feeding of aluminum sheets can be achieved, which improves the quality and weight of casting and saves physical labor.

[0028] 4. Due to the obstruction of the baffle, the drive rack slides upward along the cavity of the collecting box and meshes with the rotating gear to rotate. The pressure spring is gradually compressed, and the rotating gear carries the receiving box to swing downward at an inclined angle. The impurities inside each screening box slide down the inclined surface of the impurity cavity into the receiving box. The impurities inside the receiving box slide down into the discharge box below, and finally slide into the collection box. This can collect and process the impurities in a concentrated manner, avoiding the flying of impurities. Attached Figure Description

[0041] The following reference Figures 1 to 11 The various embodiments of the present invention will be described in detail. Those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0042] A casting processing feeding mechanism, such as Figures 1-4 , Figure 9 As shown, the system includes three support frames 1, which improves stability. A collar is fixedly mounted on the top of each of the three support frames 1. A processing cylinder 2 is fixedly mounted inside the collar. The top of the processing cylinder 2 is closed, and the bottom is open. A fixing ring 3 is fixedly mounted on the upper part of the inner wall of the processing cylinder 2. Multiple screening boxes 4 are evenly rotatably mounted on the inner wall of the fixing ring 3. There are four screening boxes 4, and each screening box 4 is fan-shaped. The four screening boxes 4 can be combined to form a circular structure. A filter screen 5 is fixedly mounted on the upper end of each screening box 4. The space between the filter screen 5 and the inner bottom of the screening box 4 is an impurity chamber. A drive motor 6 is fixedly mounted on the top of the processing cylinder 2. The positioning shaft 7 at the end passes through the top of the processing cylinder 2 and extends into the interior of the processing cylinder 2. When the four filter screens 5 are on the same plane, the bottom surface of the positioning shaft 7 is not in contact with the filter screens 5. Multiple stirring rods 8 are provided on the positioning shaft 7. The processing cylinder 2 is equipped with a drive device located below the fixed ring 3. The support frame 1 is equipped with a feeding frame 9. Rotating rollers are rotatably installed at the front and rear ends of the feeding frame 9. A conveyor belt 10 is installed between the two rotating rollers. A conveyor motor is fixedly installed on the feeding frame 9. The rotating shaft of the conveyor motor is coaxially and fixedly connected to the rotating roller on the rear side. The conveyor motor and the drive motor 6 are simultaneously connected to the controller. The controller is connected to an external power supply. The top of the processing cylinder 2 is fixedly connected to the feeding port 11.

[0043] In use, personnel place smaller aluminum parts through the feeding port 11 onto the top surface of the four filter screens 5. After a set amount of aluminum parts is placed, the power is turned on, and the controller starts the drive motor 6. The positioning shaft 7, carrying multiple stirring rods 8, stirs the aluminum parts on the four filter screens 5. The aluminum parts collide with each other, and impurities and dust adhering to the aluminum parts are shaken off. The impurities and dust fall through the holes in the filter screens 5 and are collected in the impurity chamber. This improves the cleanliness of the outer surface of the aluminum parts and the purity of the casting. After the impurities on the aluminum parts are cleaned, the drive device moves the four screening boxes 4 downwards, and the four screening boxes 4 move away from each other, thus opening a certain gap. At this time, each Each screening box 4 forms a downward tilt angle, and the aluminum parts will slide down the inclined surface of the filter screen 5 through the gaps onto the conveyor belt 10. The conveyor motor drives the two rotating rollers and the conveyor belt 10 to rotate. The conveyor belt 10 transports the aluminum parts to the melting area for melting and casting. After the aluminum parts on the four filter screens 5 have all fallen onto the conveyor belt 10, the drive device pushes the four screening boxes 4 upward to return them to their original positions for continued use. Since the impurities fall into the impurity chamber, they will not fall to the ground, which improves the cleanliness of the bottom surface and reduces the physical labor of personnel. In addition, the continuous stirring of the stirring rod 8 accelerates the falling of impurities on the aluminum parts without causing injury to personnel, thus improving work efficiency.

[0044] like Figure 3 , Figure 4 , Figure 6 As shown, the driving device includes a pull ring 12, which is slidably mounted on the inner wall of the processing cylinder 2. An upper fixing block 13 is fixedly mounted on the bottom end of each screening box 4. Lower fixing blocks 14 are evenly fixedly mounted on the pull ring 12. A linkage rod 15 is rotatably mounted on each upper fixing block 13, and the other end is rotatably mounted on the corresponding lower fixing block 14.

[0045] In use, the pull ring 12 moves the four linkage rods 15, and each linkage rod 15 causes the inner end of the corresponding screening box 4 to swing downward. The four screening boxes 4 move away from each other, thus opening a certain gap. Each screening box 4 tilts downward at a certain angle, and the aluminum parts will slide down the surface of the filter screen 5 and onto the conveyor belt 10 through the gap. This can quickly open each screening box 4 and improve casting efficiency.

[0046] like Figure 2 , Figure 8 , Figure 10As shown, a receiving hopper 16 located below the pull ring 12 is fixedly installed on the inner wall of the processing cylinder 2. The tip of the receiving hopper 16 is set downwards. A crushing cylinder 17 is fixedly connected through the tip of the receiving hopper 16. The crushing cylinder 17 is set vertically. A positioning rod 18 is fixedly installed on the inner end of the crushing cylinder 17. A drive shaft 19 is rotatably installed on the positioning rod 18. Multiple crushing blades 20 are evenly fixedly installed on the drive shaft 19. A strainer 21 is provided at the bottom end of the crushing cylinder 17. The mesh size of the strainer 21 is larger than that of the filter screen 5.

[0047] During use, the aluminum parts gradually slide down the inclined surface of the filter screen 5 and onto the receiving hopper 16 through the gap below. The aluminum parts then gradually slide down the inclined inner wall of the receiving hopper 16 into the crushing cylinder 17. The drive shaft 19 drives multiple crushing blades 20 to rotate rapidly. The crushing blades 20 can break the aluminum parts into pieces. The broken aluminum pieces fall down through the screen 21. Because the broken aluminum pieces or blocks are small in size, the melting speed of the aluminum parts is accelerated, and the aluminum parts are melted more thoroughly, thus improving the casting efficiency.

[0048] like Figure 4 , Figure 6 , Figure 7 As shown, a collection box 22 is fixedly passed through the tip of the bottom of each screening box 4. A discharge port 23 is opened at the lower end of each collection box 22. A receiving box 24 is rotatably installed on the inner end of each discharge port 23. The receiving box 24 can be completely closed inside the discharge port 23. A discharge device is provided on the processing cylinder 2 located below each receiving box 24.

[0049] During use, the positioning shaft 7 carries multiple stirring rods 8 to stir the aluminum parts on the four filter screens 5. The aluminum parts collide with each other, and the impurities and dust adhering to the aluminum parts will be shaken off. The impurities and dust fall into the impurity chamber through the holes on the filter screen 5. Some of the impurities will fall into the receiving box 24, which can improve the purity of the aluminum parts.

[0050] After the impurities on the aluminum parts are cleaned, the pull ring 12 moves the four linkage rods 15. Each linkage rod 15 causes the inner end of the corresponding screening box 4 to swing downward, and the four screening boxes 4 move away from each other, thus opening a certain gap. Each screening box 4 tilts downward at a certain angle, and the aluminum parts will fall down along the tilt angle. At the same time, the impurities inside each screening box 4 will also slide down along the tilted surface of the impurity chamber into the collection box 22 and the receiving box 24, preventing impurities from falling to the ground and improving the cleanliness of the ground.

[0051] like Figure 1 , Figure 2 , Figure 9As shown, a positioning block 25 is fixedly installed on the upper outer side of the processing cylinder 2, and a stabilizing block 26 is fixedly installed on the lower outer side of the processing cylinder 2. The positioning block 25 and the stabilizing block 26 are arranged vertically correspondingly. A linkage shaft 27 is rotatably installed between the positioning block 25 and the stabilizing block 26. A first sprocket assembly 28 is installed between the linkage shaft 27 and the positioning shaft 27. The first sprocket assembly 28 includes two first sprockets and a first chain. First sprockets are coaxially fixedly installed on the positioning shaft 7 and the linkage shaft 27, respectively. A first chain connects the two first sprockets and passes through the processing cylinder 2. A second sprocket assembly 29 is installed between the linkage shaft 27 and the drive shaft 19. The second sprocket assembly 29 includes two second sprockets and a second chain. Second sprockets are coaxially fixedly installed on the drive shaft 19 and the linkage shaft 27, respectively. A second chain connects the two second sprockets and passes through the crushing cylinder 17 and the processing cylinder 2.

[0052] When the power is turned on, the controller starts the drive motor 6, and the positioning shaft 7 rotates the stirring rod 8, the first sprocket group 28, the linkage shaft 27, the second sprocket group 29 and the drive shaft 19, thereby realizing the linkage between the various components, improving convenience and saving costs.

[0053] like Figure 2 , Figure 4 As shown, a mounting block 30 is fixedly installed on the outer end of the crushing cylinder 17, and a gear disk 31 is rotatably mounted on the mounting block 30. The top surface of the gear disk 31 slides in contact with the bottom surface of the crushing cylinder 17. A discharge hole 32 is opened on the gear disk 31. A linkage gear 33 that meshes with the gear disk 31 is coaxially fixedly installed on the linkage shaft 27. The linkage gear 33 passes through the processing cylinder 2. A feeding hopper 34 is fixedly passed through the bottom end of the processing cylinder 2.

[0054] In use, the linkage shaft 27 drives the linkage gear 33 to rotate, and the linkage gear 33 meshes with the gear disk 31 to rotate. The crushed aluminum pieces fall through the strainer 21 onto the top surface of the gear disk 31 and are located inside the crushing cylinder 17. When the discharge hole 32 coincides with the bottom port of the crushing cylinder 17, the crushed aluminum pieces fall quickly into the discharge port of the feeding hopper 34 through the discharge hole 32. The aluminum pieces finally fall onto the conveyor belt 10. The conveyor motor drives the two rotating rollers and the conveyor belt 10 to rotate. The conveyor belt 10 transports the aluminum pieces to the melting area for melting and casting. Since the discharge hole 32 coincides with the bottom port of the crushing cylinder 17 intermittently, this can achieve intermittent quantitative feeding of aluminum pieces and ensure that the amount of aluminum pieces on the conveyor belt 10 is basically the same, which improves the quality and weight of casting. It also eliminates the need for manual quantitative distribution of aluminum pieces, saving physical labor.

[0055] like Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 10 As shown, the discharge device includes a discharge box 35. Four mounting ports are evenly distributed on the circumferential end of the processing cylinder 2. Each mounting port is located directly below the corresponding receiving box 24, and an inclined discharge box 35 is fixedly installed inside each mounting port. The inner end of the discharge box 35 faces upwards, and the outer end faces downwards. A portion of the discharge box 35 is located inside the processing cylinder 2, and another portion is located at the outer end of the processing cylinder 2. An upwardly oriented inclined rod 36 is fixedly installed on the inner end of each discharge box 35, and a baffle 37 is fixedly installed on the top of each inclined rod 36. A cavity is provided at the bottom tip of the collection box 22. A fixed shaft is rotatably installed on the inner wall of the cavity. The inner end of the receiving box 24 is fixedly installed on the fixed shaft. The rotating gear 38 is coaxially fixedly installed on the fixed shaft. A drive rack 39 that meshes with the rotating gear 38 is slidably installed inside each cavity. A pressure spring 40 is fixedly installed at the bottom end of each drive rack 39. The top end of each pressure spring 40 is fixedly installed on the bottom surface of the collection box 22. When the four screening boxes 4 are closed together and on the same plane, the receiving box 24 is completely hidden inside the discharge port 23.

[0056] like Figure 1 As shown, a discharge box 41 is fixedly connected to the bottom of the outer end of each discharge box 35, and a collection box 42 located below each discharge box 41 is fixedly installed on the outer end of the processing cylinder 2. The bottom end of the discharge box 41 is fixedly connected to the inside of the collection box 42. The collection box 42 has a ring structure, and a material picking door is provided on the bottom end of the collection box 42.

[0057] In use, the pull ring 12 moves the four linkage rods 15, and each linkage rod 15 causes the inner end of the corresponding screening box 4 to swing downward. The four screening boxes 4 gradually open a certain angle away from each other. At the same time, the drive rack 39 contacts the corresponding baffle 37. When the screening box 4 continues to move downward, due to the obstruction of the baffle 37, the drive rack 39 will slide upward along the cavity of the collection box 22 and mesh with the rotating gear 38 to rotate. The pressure spring 40 is gradually compressed, and the rotating gear 38 causes the receiving box 24 to swing downward at an inclined angle. The impurities inside each screening box 4 slide down the inclined surface of the impurity cavity into the receiving box 24. Since the receiving box 24 is inclined, the impurities inside the receiving box 24 will slide down into the discharge box 35 below. Then the impurities slide down into the collection box 42 through the drop box 41. Personnel can put the impurities inside into a suitable area through the material handling door. This can collect and process the impurities in a centralized manner, avoid the impurities from flying, reduce air pollution and the workload of personnel.

[0058] As the four screening boxes 4 gradually close together, the rebound force of the pressure spring 40 pushes the drive rack 39 to reset, and at the same time the receiving box 24 is hidden in the discharge port 23.

[0059] like Figure 2 , Figure 3 As shown, the processing cylinder 2 has a vertical sliding hole 43. A pull block 44 located inside the sliding hole 43 is fixedly installed on the pull ring 12. An electric telescopic rod 45 is provided on the pull block 44. The bottom end of the telescopic rod 45 passes through the corresponding discharge box 35 and is fixedly connected to the processing cylinder 2. The top end of the telescopic rod 45 is fixedly connected to the pull block 44. The lower end of the linkage shaft 27 passes through the corresponding discharge box 35. The telescopic rod 45 is connected to the controller. The telescopic rod 45 can slide up and down along the sliding hole 43 with the pull block 44, thereby opening the four screening boxes 4 through the corresponding components. When the impurities inside the screening box 4 are not cleaned, the telescopic rod 45 can quickly extend and retract, and the screening box 4 swings and vibrates up and down, causing the impurities to fall down.

[0060] A method for feeding a casting machining mechanism includes the following steps:

[0061] Step 1: Personnel place the aluminum parts through the feeding port 11 onto the top surface of the four filter screens 5, turn on the power, and the controller starts the drive motor 6.

[0062] Step 2: The positioning shaft 7, along with multiple stirring rods 8, stirs the aluminum parts on the four filter screens 5. Impurities and dust fall into the impurity chamber through the holes in the filter screens 5.

[0063] Step 3: The telescopic rod 45 slides down along the sliding hole 43 with the pull block 44, and the pull ring 12 moves with the four linkage rods 15. Each linkage rod 15 swings down with the inner end of the corresponding screening box 4, and the aluminum parts slide down onto the receiving hopper 16 through the gap below.

[0064] Step 4: The drive rack 39 contacts the corresponding baffle 37. Due to the obstruction of the baffle 37, the drive rack 39 slides upward along the cavity of the collection box 22 and meshes with the rotating gear 38 to rotate. The pressure spring 40 is gradually compressed, and the rotating gear 38 swings the receiving box 24 downward at an inclined angle. The impurities inside each screening box 4 slide down the inclined surface of the impurity cavity into the receiving box 24.

[0065] Step 5: Impurities inside receiving box 24 will slide into discharge box 35 below, and then the impurities will slide into collection box 42 through discharge box 41.

[0066] Step 6: The drive shaft 19 rotates rapidly with multiple crushing blades 20. The crushed aluminum pieces fall onto the top surface of the gear disk 31 through the strainer 21. When the discharge hole 32 coincides with the bottom port of the crushing cylinder 17, the crushed aluminum pieces fall quickly into the discharge port of the hopper 34 through the discharge hole 32. The aluminum pieces finally fall onto the conveyor belt 10.

[0067] Step 7: The conveyor motor drives the two rotating rollers and the conveyor belt 10 to rotate. The conveyor belt 10 transports the aluminum parts to the melting area for melting and casting.
