Abstract

This utility model discloses a special ceramic isostatic pressing molding filling device, belonging to the field of ceramic production. The device includes a fixed support and a hopper slidably connected to the fixed support. The fixed support is equipped with a lifting component for adjusting the hopper. When the lifting component is in operation, the hopper moves vertically and horizontally along the fixed support. This utility model, through the height adjustment of the hopper by the lifting component, facilitates the loading of materials into the hopper by workers and allows the hopper to fill molds of different sizes, thereby increasing the applicability of the filling device. Furthermore, the driving component rotates the stirring rod, which not only prevents the special ceramic raw material from clogging inside the hopper but also drives the striking component to reciprocate by striking the mold.

Description

Technical Field

[0001] This utility model relates to the field of ceramic production technology, and in particular to a special ceramic isostatic pressing filling device. Background Technology

[0002] In the preparation of special ceramics, carefully formulated inorganic materials need to be incorporated into the ceramic blank and sintered at a high temperature of about 1360 degrees Celsius to give it stable and reliable antistatic properties, thus making it an innovative ceramic material. Isostatic pressing technology involves placing the object to be processed in a sealed container filled with liquid and gradually applying pressure with the help of a pressurization system to make the surface of the object uniformly stressed. While maintaining its appearance and shape, it reduces the intermolecular distance, increases the density, and thus optimizes the physical properties of the material.

[0003] Before isostatic pressing of special ceramics, the special ceramic raw materials need to be filled into the mold in advance. Traditional filling methods often rely on manual feeding, followed by manual hammering of the mold to increase the filling density of the special ceramic raw materials, thereby enhancing the strength and stability of the ceramics after isostatic pressing.

[0004] However, in ceramic production practice, the molds used vary in size. For larger molds, manual filling is quite inconvenient. In addition, relying solely on manual hammering of the mold to increase the filling density is not only inefficient, but also makes it difficult to ensure the uniformity of the processing effect, which will undoubtedly have an adverse impact on the production quality of ceramic products. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art where manual feeding is inefficient when filling molds of different sizes, and the method of simply relying on manual tapping of the mold to increase the filling density is difficult to guarantee the uniformity of the process. Therefore, a special ceramic isostatic pressing filling device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A special ceramic isostatic pressing filling device includes a fixed support and a hopper slidably connected to the fixed support. The fixed support is provided with a lifting member for adjusting the hopper. When the lifting member is working, the hopper moves vertically and horizontally along the fixed support. A stirring rod is installed on the hopper. The hopper is provided with a driving member for controlling the rotation of the stirring rod. The hopper is provided with a striking member. When the stirring rod rotates, the striking member tends to move closer to or further away from the center of the hopper.

[0008] To improve the hopper's lifting capacity and broaden the applicability of the filling device, the lifting component preferably includes: at least two lead screws rotatably mounted on the fixed bracket, each lead screw being threaded with a threaded sleeve fixedly connected to the hopper; each of the two lead screws being fixedly fitted with a toothed synchronous pulley, the two toothed synchronous pulleys being connected by a toothed transmission belt; and a first motor fixedly mounted on the fixed bracket, the output end of the first motor being fixedly connected to one of the lead screws.

[0009] To further protect the toothed synchronizing pulley and the toothed synchronizing belt, a protective shell is fitted over the outer side of the toothed synchronizing pulley, and the protective shell is fixedly connected to the fixed bracket.

[0010] To drive the stirring rod to rotate, preferably, the driving component includes a second motor fixedly mounted on the hopper, the output end of the second motor being fixedly connected to the stirring rod.

[0011] To strike the mold at the bottom of the hopper, causing displacement of the special ceramic raw material inside and thereby increasing the mold filler density, preferably, the striking component includes: an L-shaped rod slidably connected to the hopper, with a striking rod fixedly connected to the end of the L-shaped rod away from the hopper; a T-shaped rod fixedly connected to the L-shaped rod, with the end of the T-shaped rod away from the L-shaped rod slidably connected inside the hopper; a tension spring sleeved on the T-shaped rod, with both ends of the tension spring fixedly connected to the hopper and the L-shaped rod respectively; and a cam fixedly sleeved on the stirring rod, the cam abutting against the L-shaped rod.

[0012] To further improve the applicability of the striking rod, the striking rod is further composed of a sleeve and a striking head, the striking head being threaded into the sleeve, and the sleeve being fixedly installed on the L-shaped rod.

[0013] To further limit the lateral movement of the L-shaped rod, a groove is provided on the hopper, and a slider that is fixedly connected to the L-shaped rod is slidably connected in the groove.

[0014] To vertically limit the hopper, preferably, at least two sliding rods are fixedly connected to the fixed bracket, and sliding sleeves that are fixedly connected to the hopper are slidably connected to the sliding rods.

[0015] To improve the stability of the vertical movement of the hopper, preferably, a limiting groove is provided on the fixed bracket, and the hopper is slidably connected in the limiting groove.

[0016] In order to control the flow of special ceramic raw materials inside the hopper, preferably, an electromagnetic valve is fixedly connected to the discharge end of the hopper.

[0017] Compared with the prior art, this utility model provides a special ceramic isostatic pressing filling device, which has the following beneficial effects:

[0018] 1. This special ceramic isostatic pressing filling device, through the striking rod consisting of a sleeve and a striking head, can adjust the length of the striking rod by rotating the striking head on the sleeve, thereby increasing the striking range of the striking rod;

[0019] 2. This special ceramic isostatic pressing filling device, through the cooperation of sliding rod and sliding sleeve, can vertically limit the hopper, thereby improving the stability of hopper lifting;

[0020] 3. This special ceramic isostatic pressing filling device, through the setting of solenoid valve, can control the flow of special ceramic raw materials inside the hopper, so as to accurately feed the material according to the filling degree of the mold;

[0021] The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model adjusts the height of the hopper by using a lifting component, which on the one hand facilitates the workers to feed materials into the hopper, and on the other hand enables the hopper to fill molds of different sizes, thereby increasing the applicability of the filling device. Furthermore, by using a driving component to drive the stirring rod to rotate, it can not only prevent the special ceramic raw materials inside the hopper from clogging, but also drive the striking component to repeatedly strike the mold. The vibration force generated by the striking causes the special ceramic raw materials inside the mold to gradually shift, thereby increasing the filling density. Attached Figure Description

[0030] Example:

[0031] Reference Figures 1-5 A special ceramic isostatic pressing filling device includes a fixed support 1 with four pulleys fixedly installed at the bottom to improve its flexibility. It also includes a hopper 2 slidably connected to the fixed support 1, with a lifting component on the fixed support 1 for adjusting the hopper 2. When the lifting component is working, the hopper 2 moves vertically and horizontally along the fixed support 1. A stirring rod 4 is installed on the hopper 2, and a drive component on the hopper 2 controls the rotation of the stirring rod 4. The drive component includes a second motor 5 fixedly installed on the hopper 2, with its output end fixedly connected to the stirring rod 4 for driving the stirring rod 4 to rotate and stir the special ceramic raw material inside the hopper 2 to prevent blockage. The hopper 2 is also equipped with a striking component that tends to move closer to or further away from the center of the hopper 2 when the stirring rod 4 rotates.

[0032] Specifically, by adjusting the height of the hopper 2 through the lifting component, it is convenient for workers to feed materials into the hopper 2, and the hopper 2 can fill molds of different sizes, thereby increasing the applicability of the filling device. Furthermore, by using the driving component to drive the stirring rod 4 to rotate, it is possible to avoid the blockage of special ceramic raw materials inside the hopper 2, and to drive the striking component to repeatedly strike the mold. The vibration force generated by the striking causes the special ceramic raw materials inside the mold to gradually shift, thereby increasing the filling density.

[0033] The lifting component includes: at least two lead screws 3, preferably two in total, with the threads on the surfaces of the two lead screws 3 in the same direction, rotatably mounted on a fixed bracket 1, with threaded sleeves 31 threadedly connected to the lead screws 3 and fixedly connected to the hopper 2, and toothed synchronous pulleys 32 fixedly fitted on both lead screws 3, the two toothed synchronous pulleys 32 being connected to each other via a toothed transmission belt; a first motor 33 fixedly mounted on the fixed bracket 1, the output end of the first motor 33 being fixedly connected to one of the lead screws 3, and a protective shell fitted on the outside of the toothed synchronous pulley 32, the protective shell being fixedly connected to the fixed bracket 1, for protecting the toothed synchronous pulley 32 and the toothed synchronous belt.

[0034] Specifically, by setting up the lifting component, when the output end of the first motor 33 drives the lead screw 3 to rotate, the threaded sleeve 31 will drive the hopper 2 to move vertically. By lifting the hopper 2, not only is manual feeding convenient, but it can also fill molds of different sizes, thereby improving its applicability.

[0035] The striking component includes: an L-shaped rod 6, slidably connected to the hopper 2, with a groove on the hopper 2, and a slider fixedly connected to the L-shaped rod 6 slidably connected in the groove for lateral limiting of the L-shaped rod 6; a striking rod 61 fixedly connected to the end of the L-shaped rod 6 away from the hopper 2, the striking rod 61 consisting of a sleeve and a striking head, the striking head being threaded into the sleeve, the sleeve being fixedly installed on the L-shaped rod 6, and the length of the striking rod 61 being adjustable by rotating the striking head on the sleeve, thereby increasing the striking range of the striking rod 61; a T-shaped rod 62 fixedly connected to the L-shaped rod 6, the end of the T-shaped rod 62 slidably connected to the hopper 2, and a tension spring 63 sleeved on the T-shaped rod 62, the two ends of the tension spring 63 being fixedly connected to the hopper 2 and the L-shaped rod 6 respectively; and a cam 64 fixedly sleeved on the stirring rod 4, the cam 64 abutting against the L-shaped rod 6.

[0036] Specifically, through the setting of the striking component, when the second motor 5 drives the stirring rod 4 to stir the special ceramic raw material inside the hopper 2, the stirring rod 4 drives the cam 64 to rotate. When the cam 64 squeezes the L-shaped rod 6, the striking rod 61 moves away from the mold. When the cam 64 releases the squeeze on the L-shaped rod 6, the tension spring 63 resets the L-shaped rod 6, causing the striking rod 61 to strike the mold. As the cam 64 continues to rotate and adjust the L-shaped rod 6, the L-shaped rod 6 drives the striking rod 61 to form a reciprocating trajectory, realizing the reciprocating striking of the mold. The vibration generated by the striking causes the special ceramic raw material inside the mold to gradually shift, thereby increasing the filler density.

[0037] At least two sliding rods are fixedly connected to the fixed bracket 1, preferably two in this case, and sliding sleeves that are fixedly connected to the hopper 2 are slidably connected to the sliding rods.

[0038] Specifically, the sliding rod and sliding sleeve work together to vertically limit the hopper 2, thereby improving the stability of the hopper 2 during lifting.

[0039] A limiting groove is provided on the fixed bracket 1, and the hopper 2 is slidably connected in the limiting groove.

[0040] Specifically, by setting the limiting groove, the hopper 2 can be vertically limited to prevent the position of the hopper 2 from shifting when it moves vertically.

[0041] A solenoid valve is fixedly connected to the discharge end of hopper 2.

[0042] Specifically, by setting up the solenoid valve, the flow of special ceramic raw materials inside the hopper 2 can be controlled, so that the material can be accurately fed according to the filling degree of the mold.

[0043] Working principle: When feeding special ceramic raw materials, the operator starts the first motor 33 using an external control switch. The output end of the first motor 33 drives one of the lead screws 3 to rotate. When the lead screw 3 rotates, it drives the toothed synchronous pulley 32 to rotate. When the toothed synchronous pulley 32 rotates, it drives the toothed synchronous belt to drive the transmission, causing the two lead screws 3 to rotate in the same direction. When the two lead screws 3 rotate, they drive the two threaded sleeves 31 to move, which can adjust the height of the hopper 2. When the hopper 2 moves down to the designated position, the operator pours the special ceramic raw materials into the hopper 2 and starts the first motor 33 again to drive the hopper 2 to move upward.

[0044] After hopper 2 moves upward to the designated position, the operator places the mold at the bottom of hopper 2 and starts the second motor 5 and solenoid valve using an external control switch. Once the solenoid valve opens, the special ceramic raw material inside hopper 2 flows downward and is discharged into the mold, thus filling the mold. The output of the second motor 5 rotates, driving the stirring rod 4 to rotate as well. The stirring rod 4 stirs the special ceramic raw material inside hopper 2, preventing blockage during discharge. Simultaneously, the rotating stirring rod 4 drives the cam 64 to rotate, which in turn squeezes the two L-shaped rods 6. The pressure causes the two L-shaped rods 6 to move in opposite directions. When the two L-shaped rods 6 move in opposite directions, they stretch the two tension springs 63 and drive the two striking rods 61 to move. When the cam 64 releases the pressure on the L-shaped rods 6, the tension springs 63 reset the L-shaped rods 6, allowing the striking rods 61 to strike the mold. As the cam 64 continues to rotate and adjust the L-shaped rods 6, the L-shaped rods 6 drive the striking rods 61 to form a reciprocating trajectory, realizing the reciprocating striking of the mold. The vibration generated by the striking causes the special ceramic raw material inside the mold to gradually shift, thereby increasing the filler density.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
