Description

Technical Field

[0001] This application relates to the field of crucible manufacturing technology, and in particular to a crucible continuous forming machine. Background Technology

[0002] A crucible is a vessel made of refractory materials such as clay, porcelain clay, and quartz. It is a deep, bowl-shaped container. Crucibles are used when items need to be heated to high temperatures. They can withstand higher temperatures than glassware. Clay crucibles, as a representative type of crucible, have advantages such as high temperature resistance, corrosion resistance, and ease of molding. To accelerate crucible production, automated equipment is used in the market for crucible molding.

[0003] Utility model patent CN220994839U discloses a crucible forming machine, comprising: a device base, with a bearing seat fixedly connected to the top of the device base; a movable frame, with movable frames slidably installed on both the left and right sides of the top of the device base, and a bottom mold fixedly connected to the inner side of the movable frame; a fixed frame, with a fixed frame fixedly connected to the top left side of the device base, and a hydraulic rod installed on the top bottom side of the fixed frame, with a forming block fixedly connected to the movable end of the hydraulic rod; a motor installed on the left side of the device base, with a shaft fixedly connected to the output end of the motor; the outer surface of the shaft has a bidirectional threaded structure, and the connection between the shaft and the movable frame is a threaded connection; and a fixed plate fixedly connected to the right side of the fixed frame. This crucible forming machine automatically demolds after pressing and forming.

[0004] Regarding the aforementioned technologies, after each crucible is formed, it remains on the support base and needs to be removed before the next forming can proceed. The crucible removal process is time-consuming and results in low production efficiency. Utility Model Content

[0005] This application provides a crucible continuous forming machine that can automatically transport the formed crucibles. If the crucibles are not removed in time, it will not affect the subsequent forming process, thereby improving production efficiency.

[0006] This application provides a crucible continuous forming machine, which adopts the following technical solution: A crucible continuous forming machine includes a frame, a motor, two bottom molds driven by the motor, a hydraulic cylinder, a forming block driven by the hydraulic cylinder to rise and fall, and a conveyor belt passing directly below the forming block. A support base is fixed to the frame, and the support base contacts the bottom surface of the upper surface of the conveyor belt. Multiple positioning rings made of rubber are fixed on the conveyor belt, and the positioning rings are arranged in an array along the length of the conveyor belt. A bearing seat is placed on each positioning ring.

[0007] By adopting the above technical solution, a support seat is placed at the beginning of the conveyor belt, and the support seat is placed on the positioning ring. The conveyor belt drives the support seat to move. When the support seat moves directly under the forming block, the conveyor belt stops, and the support seat supports the weight above. After the forming step is completed, the crucible is placed on the support seat, and the conveyor belt drives the next support seat to the forming position. The above steps are repeated to achieve continuous production.

[0008] Optionally, the support base is fixed to the frame via two side walls, and the bottom end of the support base is provided with a clearance groove for the lower end face of the conveyor belt to pass through.

[0009] By adopting the above technical solution, the support base can be prevented from affecting the operation of the conveyor belt.

[0010] Optionally, the telescopic end of the hydraulic cylinder is fixed with a bracket, the forming block is located on the bracket, the bracket is fixed with a pressure ring, and the bottom surface of the pressure ring is used to form the top surface of the crucible.

[0011] By adopting the above technical solution, when the crucible is formed in the bottom mold, the pressure ring blocks the top surface of the bottom mold and forms the top surface of the crucible.

[0012] Optionally, the bracket is fixed with a second motor, the inner wall of the pressure ring is threaded, the forming block is located inside the pressure ring and threadedly connected to the pressure ring, and the forming block is driven by the second motor.

[0013] By adopting the above technical solution, when the second motor runs, it drives the molding block to rotate. At the same time, due to the threaded connection with the pressure ring, the molding block moves upward, thereby realizing the sliding separation of the molding block from the inner wall of the crucible.

[0014] Optionally, a spline shaft is fixed to the output end of the second motor, and a spline sleeve is coaxially fixed to the forming block, with the spline shaft and the spline sleeve being slidably connected.

[0015] By adopting the above technical solution, power can be transmitted through the spline shaft and spline sleeve, and the two can slide relative to each other.

[0016] Optionally, a sliding rod is fixed to the side wall of the bottom mold, and the frame is provided with a guide groove for the sliding rod to slide.

[0017] By adopting the above technical solution, the sliding direction of the slide rod is stabilized and the rotation of the slide rod is prevented through the sliding connection between the slide rod and the guide groove.

[0018] Optionally, the output end of the motor is fixed with a bidirectional screw, the two ends of the bidirectional screw have opposite threads, and the two slide rods are respectively threaded to the two ends of the bidirectional screw.

[0019] By adopting the above technical solution, the motor drives the bidirectional screw to rotate, thereby causing the two slide rods to move closer or further apart, thus realizing the opening and closing operation of the two bottom molds.

[0020] Optionally, the top surface of the support base slides against the bottom surface of the bottom mold.

[0021] By adopting the above technical solution, when the two bottom molds are combined, the support seat can support the weight of the bottom molds and also support the downward pressure generated during the crucible forming process, so that the two bottom molds are under stable force and the two bottom molds are prevented from separating.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a conveyor belt, the formed crucibles can be transported automatically. If the crucibles are not removed in time, it will not affect the subsequent forming, thus improving production efficiency. 2. This prevents the crucible from falling and hitting the support, reducing the risk of crucible deformation; 3. The bottom mold is subjected to stable force during crucible forming, which prevents the two bottom molds from separating and improves the pass rate. Attached Figure Description

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] Reference Figure 1 This embodiment discloses a continuous crucible forming machine, including a frame 1 and a conveyor belt 2. The frame 1 is equipped with a motor 3 and two bottom molds 4 driven by the motor 3. The frame 1 is also equipped with a hydraulic cylinder 5 and a forming block 6 driven by the hydraulic cylinder 5 to rise and fall. The conveyor belt 2 passes directly below the forming block 6. The two bottom molds 4 are combined to form a complete container shape for forming the bottom shape of the crucible, and the forming block 6 is used to form the inner wall shape of the crucible.

[0027] Reference Figure 1 and Figure 2 The frame 1 is fixed with a support base 11, which contacts the bottom surface of the upper belt surface of the conveyor belt 2. The length of the support base 11 extends along the length of the conveyor belt 2, providing support for the upper belt surface of the conveyor belt 2 and preventing it from deforming downwards under heavy pressure. The top surface of the support base 11 is coated with a Teflon layer to reduce friction. The support base 11 is fixed to the frame 1 via two side walls, and the bottom end of the support base 11 has a clearance groove 12 for the lower end surface of the conveyor belt 2 to pass through. The support base 11 is fixed with several legs 13, which contact the ground to provide further support for the support base 11.

[0028] Multiple rubber positioning rings 21 are fixed on the conveyor belt 2, arranged in an array along the length of the conveyor belt 2. When the conveyor belt 2 bends and deforms, the positioning rings 21 deform along with it. A support seat 22 is placed on each positioning ring 21, and the support seat 22 has a groove for placing the bottom of the formed crucible. Positioning the support seat 22 using the positioning rings 21 facilitates its positioning, ensuring consistent spacing between adjacent support seats 22 and allowing the support seat 22 to pass directly beneath the forming block 6. The drive motor of the conveyor belt 2 is a servo motor, capable of precise angle control. Each run of the conveyor belt 2 moves the support seat 22 one by one to directly beneath the forming block 6, where it remains for a period of time to allow the crucible to form.

[0029] Reference Figure 1 A sliding rod 41 is fixed to the side wall of the bottom mold 4. The frame 1 is provided with a guide groove 14 for the sliding rod 41 to slide. The motor 3 is fixed to the frame 1. A bidirectional screw 31 is fixed to the output end of the motor 3. The two ends of the bidirectional screw 31 have opposite threads. The two sliding rods 41 are respectively threaded to the two ends of the bidirectional screw 31. The bidirectional screw 31 is rotatably connected to the frame 1. The motor 3 drives the bidirectional screw 31 to rotate, thereby causing the two sliding rods 41 to move closer or further apart, thus realizing the opening and closing operation of the two bottom molds 4. The sliding connection between the sliding rod 41 and the guide groove 14 stabilizes the sliding direction of the sliding rod 41 and prevents the sliding rod 41 from rotating.

[0030] The top surface of the support base 22 slides against the bottom surface of the bottom mold 4. When the two bottom molds 4 are combined, the support base 22 can support the weight of the bottom molds 4 and also support the downward pressure generated during the crucible forming process, thus stabilizing the two bottom molds 4 and preventing them from separating. As the two bottom molds 4 move away from each other, the top surface of the bottom mold 4 gradually disengages from the support base 22, preventing obstruction of the horizontal movement of the support base 22. It should be noted that the edges where the bottom mold 4 contacts the support base 22 are chamfered to facilitate the sliding of the bottom mold 4 onto the support base 22.

[0031] The cylinder body of the hydraulic cylinder 5 is fixed to the frame 1, and a bracket 51 is fixed to the telescopic end of the hydraulic cylinder 5. The forming block 6 is located on the bracket 51. A pressure ring 52 is fixed to the bracket 51, and the bottom surface of the pressure ring 52 is used to form the top surface of the crucible.

[0032] Reference Figure 3 The bracket 51 is fixed with a second motor 61. The inner wall of the pressure ring 52 is threaded. The forming block 6 is located inside the pressure ring 52 and is threadedly connected to the pressure ring 52. The forming block 6 is driven by the second motor 61. Specifically, the output end of the second motor 61 is fixed with a spline shaft 62. The forming block 6 is coaxially fixed with a spline sleeve 63. The spline shaft 62 and the spline sleeve 63 are slidably connected. Power can be transmitted through the spline shaft 62 and the spline sleeve 63, and the two can slide relative to each other.

[0033] The implementation principle of a crucible continuous forming machine according to an embodiment of this application is as follows: A support seat 22 is placed at the starting end of the conveyor belt 2, and the support seat 22 is placed on the positioning ring 21. The conveyor belt 2 drives the support seat 22 to move. When the support seat 22 moves directly below the forming block 6, the conveyor belt 2 stops, and the motor 3 drives the two bottom molds 4 to combine into a complete container. Then, a certain amount of clay is put into the bottom mold 4, the hydraulic cylinder 5 is extended, the forming block 6 and the pressure ring 52 move downward, the forming block 6 extrudes and shapes the clay in the bottom mold 4, and the pressure ring 52 blocks the top surface of the bottom mold 4 and shapes the top surface of the crucible.

[0034] After the crucible is formed, motor 3 reverses to move the two bottom molds 4 away from each other. At this point, the clay in the crucible adheres to the outside of the forming block 6 by static friction and will not fall off. Hydraulic cylinder 5 extends, moving the crucible downwards until its lower end contacts the support seat 22. Then, motor 61 is operated, causing the forming block 6 to rotate. Simultaneously, due to the threaded connection with the pressure ring 52, the forming block 6 moves upwards, thus achieving sliding separation between the forming block 6 and the inner wall of the crucible. At this point, the friction between the forming block 6 and the crucible cannot support the weight of the crucible, and the crucible rests on the support seat 22 due to gravity. Then, hydraulic cylinder 5 is shortened and reset, while motor 61 reverses and resets. Conveyor belt 2 moves the next support seat 22 to the forming position, and the above steps are repeated to achieve continuous production.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
