Description

Technical Field

[0001] The invention belongs to the technical field of presses, and in particular relates to a continuous feeding press for processing ceramic materials. Background Art

[0002] The press is an important molding equipment in industrial production. It is mainly used for the molding of powdered materials. It has the advantages of wide application and high production efficiency. It is used for the pressing and molding of ceramic powder, metal powder and rubber powder.

[0003] After searching, the national patent publication number CN 109878137 A discloses a continuous feeding press, including a frame, a workbench is arranged on the top surface of the frame along the length direction of the frame, the top of the front section of the workbench constitutes an extrusion area, and the top of the rear section constitutes a feeding area; a die hole is arranged on the top surface of the workbench in the extrusion area, an extrusion device is arranged above the extrusion area, and an ejection device is arranged below the extrusion area; a feeding device is also arranged on the workbench; the feeding device includes a feeding frame and a driving assembly, the feeding frame includes an inner frame and an outer frame, the outer frame is connected to the driving assembly, and can reciprocate between the extrusion area and the feeding area under the drive of the driving assembly.

[0004] The existing continuous feeding press for ceramic material processing has the following shortcomings: 1. The feeding device moves periodically to the bottom of the hopper. When the hopper adds materials to the feeding device, it is necessary to control the solenoid valve to open through the control system to realize the discharge, which is more troublesome and prone to malfunction during long-term use, resulting in less material discharge or even no material discharge; 2. During the feeding process, the feeding device only falls into the die hole naturally by the gravity of the material. Since the material is in powder form and is relatively fluffy, it is easy to form gaps in the die hole during the natural falling process, resulting in uneven material filling, thereby affecting the quality of the molded product; 3. When squeezing the material in the die hole, the ejection device needs to bear a large pressure, that is, it generates increased pressure on the rotating shaft. When working for a long time, it is easy to cause the rotating shaft to bend laterally or even break, which not only causes economic losses, but also affects the continuous production and reduces work efficiency.

[0015] In the above-mentioned continuous loading press for processing ceramic materials, a feed hopper is also installed on the workbench, and a collecting trough is provided on one side of the workbench. The feed hopper is L-shaped and the lower end extends into the collecting trough. A buffer plate is rotatably connected to the inner wall of the feed hopper through a hinge. The buffer plate is inclined and has an angle of 60° with the horizontal plane. The lower end of the buffer plate is fixedly connected to the inner wall of the feed hopper through a buffer spring.

[0016] Compared with the existing technology, the advantages of this continuous feeding press for ceramic material processing are:

[0017] 1. The present invention sets a driving mechanism, which can drive the first pulley to rotate through the driving motor, and then drive the second pulley and the belt to rotate. The belt drives the outer cylinder to move through the connecting rod, and then the driving motor periodically rotates forward and reverse to drive the feeding mechanism to reciprocate between the feeding mechanism and the extrusion mechanism, thereby realizing continuous transportation of materials, and the transportation process is faster and more stable.

[0018] 2. The present invention provides a feeding mechanism. When the feeding mechanism moves on the surface of the workbench, it can drive the material in the inner cylinder to move and feed the die hole. During the feeding process, the feeding motor drives the rotating disk to rotate. The protrusions on the rotating disk periodically contact the protrusions on the fixed disk, driving the inner cylinder to rock back and forth in the outer cylinder, and then driving the material in the inner cylinder to rock back and forth, so that the material falls evenly into the die hole, ensuring that the material is evenly filled into the die hole. Moreover, when the inner cylinder rocks back and forth, it drives the gear to move back and forth. Because the gear is meshed with the rack, the gear drives the rotating shaft and three scrapers to rotate, scraping the material in the inner cylinder, so that the material in the die hole is filled more fully and evenly.

[0019] 3. The present invention sets a feeding mechanism. When the feeding mechanism moves to the bottom of the feeding mechanism, the wedge-shaped push block moves to the bottom of the slide bar, pushing the slide bar to move upward, and the slide bar drives the lifting plate to move upward. At this time, the lifting plate is separated from the bottom plate, and the material in the feed barrel can leak downward from the through hole to the inner barrel below. There is no need to set up a solenoid valve controlled by a control system, so that automatic feeding into the inner barrel can be achieved. The operation is stable and easy to operate. When the feeding mechanism moves toward the extrusion mechanism, the slide bar moves downward and resets under the elastic force of the feeding spring, and then drives the lifting plate to contact and fit with the bottom plate again to close the through hole.

[0020] 4. The present invention provides an extrusion mechanism, which can drive the extrusion plate to move downward through the hydraulic cylinder, and extrude the material in the die hole through the pressure head under the extrusion plate. The extrusion plate slides downward under the limiting action of the guide rod, and the operation is stable and safe.

[0021] 5. The present invention sets an ejection mechanism, starts the ejection motor to rotate forward, drives the screw to rotate, and the screw drives the two threaded sleeves to approach each other, and then drives the ejection plate to move upward through the rotating rod, and the material formed in the die hole is ejected upward through the ejector rod and the ejector block. After the material is ejected, the material can be pushed in the direction of the material feed hopper through the push plate. After the ejection is completed, the ejection motor rotates in the opposite direction to drive the ejector rod to move downward and reset. During the working process of the extrusion mechanism, when the pressure borne by the ejection mechanism is transmitted to the screw, the pressure is decomposed by the inclined rotating rod into two components along the horizontal and longitudinal directions of the screw, which greatly reduces the lateral pressure on the screw, prevents the screw from bending or breaking due to pressure, ensures the continuity of production work, and improves work efficiency.

[0022] 6. The present invention sets a buffer plate. After the material enters the feed hopper, it will first fall on the buffer plate. Since the buffer plate is set at an angle, the impact force on the material is effectively reduced, and the speed of the material is greatly reduced after contacting the buffer plate. The buffer spring is forced to contract and further play a buffering role. The contraction of the buffer spring drives the buffer plate to rotate, so that the material with a lower falling speed rolls along the surface of the buffer plate to the collecting trough below, preventing the material from being deformed and damaged due to falling and impact, thereby ensuring product quality.

The outer cylinder 51 is sleeved outside the inner cylinder 52, and the outer cylinder 51 and the inner cylinder 52 are both slidably connected to the upper surface of the workbench 2. The feeding motor 53 is installed on the side wall of the outer cylinder 51, and the output shaft of the feeding motor 53 extends into the outer cylinder 51 and is coaxially fixedly connected to the rotating disk 54. The fixed disk 55 is fixedly installed on the side wall of the inner cylinder 52. The rotating disk 54 and the fixed disk 55 are coaxially arranged. The two protrusions 56 are both semicircular and are respectively fixedly welded to the opposite side walls of the fixed disk 55 and the rotating disk 54. There are four feeding springs 57, and the two ends of the feeding spring 57 are respectively fixedly connected to the inner cylinder 52 and the outer cylinder 51;

[0035] When the feeding mechanism 5 moves on the surface of the workbench 2, it can drive the material in the inner cylinder 52 to move and feed the die hole 3. During the feeding process, the feeding motor 53 drives the rotating disk 54 to rotate, and the protrusions 56 on the rotating disk 54 periodically contact the protrusions 56 on the fixed disk 55, driving the inner cylinder 52 to swing back and forth in the outer cylinder 51, and then driving the material in the inner cylinder 52 to swing back and forth, so that the material falls evenly into the die hole 3, ensuring that the material is evenly filled into the die hole 3, and when the inner cylinder 52 swings back and forth, it drives the gear 582 to move back and forth. Because the gear 582 is meshed with the rack 581, the gear 581 drives the rotating shaft 583 and the three scrapers 584 to rotate, scraping the material in the inner cylinder 52, so that the material in the die hole 3 is filled more fully and evenly.

[0036] Refer to the attached Figure 4 Specifically, the scraper assembly 58 includes a rack 581, a gear 582, a rotating shaft 583 and a scraper 584.

[0037] Refer to the attached Figure 5Specifically, the feeding mechanism 4 includes a feeding cylinder 41, a bottom plate 42, a lifting plate 43, a through hole 44, a fixing rod 45, a sliding rod 46, a feeding spring 47, and a sealing plate 48. The feeding cylinder 41 is fixedly installed on the upper surface of the workbench 2, the bottom plate 42 is fixedly connected to the bottom of the feeding cylinder 41, and the lifting plate 43 is slidably connected in the feeding cylinder 41. The bottom plate 42 and the lifting plate 43 are both arranged with a downward concave shape in the middle, and the bottom plate 42 and the lifting plate 43 are both provided with a through hole 44. The through holes 44 are staggered, two fixed rods 45 are respectively fixedly connected to the side walls on both sides of the feed barrel 41, two sliding rods 46 are respectively fixedly connected to the side walls on both sides of the lifting plate 43, the other end of the sliding rod 46 extends to the outside of the feed barrel 41 and is connected to the fixed rod 45 through a feeding spring 47, a sliding groove is provided on the side wall of the feed barrel 41, the sliding rod 46 is located in the sliding groove and is slidably connected to the side wall of the sliding groove, a sealing plate 48 is fixedly connected to the sliding rod 46, and the sealing plate 48 slides in a sealed manner with the side wall of the feed barrel 41.

[0038] Refer to the attached Figure 8 Furthermore, a wedge-shaped push block 511 is fixedly connected to the side wall of the outer cylinder 51, and the wedge-shaped push block 511 matches the slide bar 46, and the slide bar 46 contacts and slides with the wedge-shaped top surface of the wedge-shaped push block 511;

[0039] During operation, when the feeding mechanism 5 moves to the bottom of the feeding mechanism 4, the wedge-shaped push block 511 moves to the bottom of the slide bar 46, pushing the slide bar 46 to move upward, and the slide bar 46 drives the lifting plate 43 to move upward. At this time, the lifting plate 43 is separated from the bottom plate 42, and the material in the feed cylinder 41 can leak downward from the through hole 44 to the inner cylinder 51 below. There is no need to set up a solenoid valve controlled by a control system, so that automatic feeding into the inner cylinder 51 can be achieved. The operation is stable and easy to operate. When the feeding mechanism 5 moves toward the extrusion mechanism 7, the slide bar moves downward and resets under the elastic force of the feeding spring 47, and then drives the lifting plate 43 to contact and fit with the bottom plate 42 again, and closes the through hole 44.

[0040] Refer to the attached Figure 2 Specifically, the driving mechanism 6 includes a driving motor 61, a first pulley 62, a second pulley 63, a belt 64 and a connecting rod 65.

[0041] During operation, the first pulley 62 is driven to rotate by the driving motor 61, and then the second pulley 63 and the belt 64 are driven to rotate. The belt 64 drives the outer cylinder 51 to move through the connecting rod 65, and then the driving motor 61 is driven to rotate forward and reverse periodically, driving the feeding mechanism 5 to reciprocate between the feeding mechanism 4 and the extrusion mechanism 7, thereby realizing continuous transportation of materials, and the transportation process is faster and more stable.

[0042] Refer to the attached Figure 2 Specifically, a pushing mechanism 9 for pushing the molding material to move is further provided on the side wall of the outer cylinder 51. The pushing mechanism 9 includes a push rod 91 and a push plate 92. The push plate 92 is arranged in an arc shape with a middle portion concave inward, and the push plate 92 is fixedly connected to the side wall of the outer cylinder 51 through the push rod 91.

[0043] During operation, the pushing mechanism 9 can move with the feeding mechanism 5, that is, when the feeding mechanism 5 moves toward the die hole 3, the material after the last extrusion molding can be pushed away by the pushing mechanism 9. The pushing plate 92 is arranged in an arc shape to prevent the material from falling out from both sides of the pushing plate 92 during pushing.

[0044] Refer to the attached Figure 1 Specifically, the extrusion mechanism 7 includes a frame 71, a hydraulic cylinder 72, a mounting plate 73, an extrusion plate 74, and a guide rod 75. The frame 71 is fixedly mounted on the upper surface of the workbench 2, the mounting plate 73 is fixedly welded in the frame 71, the hydraulic cylinder 72 is mounted on the mounting plate 73, the output end of the hydraulic cylinder 72 extends to the bottom of the mounting plate 73 and is fixedly connected to the extrusion plate 74, the lower surface of the extrusion plate 74 is provided with a pressure head matching the die hole 3, the upper and lower ends of the four guide rods 75 are fixedly connected to the mounting plate 73 and the workbench 2 respectively, and the guide rods 75 penetrate the extrusion plate 74 and slide in cooperation with the extrusion plate 74;

[0045] During operation, the hydraulic cylinder 72 can drive the extrusion plate to move downward, and the material in the die hole 3 can be extruded and formed by the pressure head below the extrusion plate 74. The extrusion plate 74 slides downward under the limiting action of the guide rod 75, and the operation is stable and safe.

[0046] Refer to the attached Figure 3Specifically, the ejection mechanism 8 includes a housing 81, an ejection motor 82, a screw 83, a threaded sleeve 84, a rotating rod 85, an ejection plate 86 and an ejector rod 87. The housing 81 is fixedly connected to the lower surface of the frame 1, the ejection motor 82 is installed in the housing 81, and the output shaft of the ejection motor 82 is coaxially fixed with the screw 83 to drive the screw 83 to rotate. The two threaded sleeves 84 are respectively sleeved on both ends of the screw 83 and are threadedly matched with the screw 83. The spiral directions of the threads at both ends of the screw 83 are opposite. There are two groups of rotating rods 85, each group of rotating rods 85 has two, and the two rotating rods 85 are rotatably connected to the upper and lower end side walls of the threaded sleeve 84, and the other ends are rotatably connected to the ejection plate 86 and the inner bottom surface of the housing 81, respectively. The upper end of the ejector rod 87 extends into the die hole 3 and is integrally formed with a ejection block, and the lower end extends into the housing 81 and is fixed to the upper surface of the ejection plate 86.

[0047] During operation, the ejection motor 82 is started to rotate forward, driving the screw rod 83 to rotate. The screw rod 83 drives the two threaded sleeves 84 to approach each other, and then drives the ejection plate 86 to move upward through the rotating rod 85, and the material formed in the die hole 3 is ejected upward through the ejector rod 87 and the ejector block. After the material is ejected, it can be pushed in the direction of the material feed hopper 10 through the push plate 92. After the ejection is completed, the ejection motor 82 rotates in the opposite direction, driving the ejector rod 83 to move downward and reset. During the operation of the extrusion mechanism 7, when the pressure borne by the ejection mechanism 8 is transmitted to the screw rod 83, the pressure is decomposed by the inclined rotating rod 85 into two components along the horizontal and longitudinal directions of the screw rod 83, which greatly reduces the lateral pressure on the screw rod 83, prevents the screw rod 83 from bending or breaking due to pressure, ensures the continuity of production work, and improves work efficiency.

[0048] See attached Figure 1 Furthermore, a feed hopper 10 is also installed on the workbench 2, and a collecting trough 103 is provided on one side of the workbench 2. The feed hopper 10 is L-shaped and the lower end extends into the collecting trough 103. A buffer plate 101 is rotatably connected to the inner wall of the feed hopper 10 through a hinge. The buffer plate 101 is inclined and has an angle of 60° with the horizontal plane. The lower end of the buffer plate 101 is fixedly connected to the inner wall of the feed hopper 10 through a buffer spring 102;

[0049] During operation, after the material is pushed into the feed hopper 10 by the pushing mechanism 9, it will first fall on the buffer plate 101. Since the buffer plate 101 is inclined, the impact force on the material is effectively reduced, and the speed of the material is greatly reduced after contacting the buffer plate 101. The buffer spring 102 is forced to contract and further play a buffering role. The contraction of the buffer spring 102 drives the buffer plate 101 to rotate, so that the material with a lower falling speed rolls along the surface of the buffer plate 101 to the collecting trough 103 below, preventing the material from being deformed and damaged due to falling and impact, thereby ensuring product quality.
