Description

Technical Field

[0001] This invention relates to the field of sieving technology for gel processing, specifically a sieving device for processing dental restorative gels. Background Technology

[0002] The sieving device for dental restorative gel processing is based on the principle of mechanical size repulsion. Through the synergistic action of a vibration system and auxiliary technology, it can classify and sieve high-viscosity, easily agglomerated dental restorative gel, remove impurities and excessively large particles, ensure the uniformity of gel particle size, and meet the precision requirements of medical-grade restorative materials. The working efficiency of this device directly affects the strength, durability, and biocompatibility of the final restoration, and therefore occupies an important position in the production of dental materials.

[0003] In traditional dental restorative gel processing, during the sieving process, tiny gel particles easily become embedded in the filter plate pores, forming a bridging phenomenon. The fine powder produced after the agglomerates are broken up adheres to the filter plate surface like glue, gradually forming a dense clogging layer that is prone to remaining on the filter plate surface. Due to the high viscosity, easy agglomeration, and strong adhesion of dental restorative gel, the gel cannot diffuse naturally like a low-viscosity liquid and easily forms an accumulation cone.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing sieving devices used for processing dental restorative gels. Summary of the Invention

[0010] Preferably, the fixing rod penetrates the inner wall of the main body, the main body has a cavity that moves to accommodate the fixing rod, and the outer wall of the fixing rod is fixedly connected to the sealing ring.

[0011] Preferably, the scraping assembly includes a fixed column fixed to the bottom end of the fixed plate, and a rotating column is slidably connected inside the fixed column, the rotating column being rotatably connected to the filter plate.

[0012] Preferably, the outer wall of the rotating column is fixedly connected to the scraper, the fixed column has a cavity that cooperates with the movement of the rotating column, and the inner wall of the cavity has a threaded groove that cooperates with the movement of the protruding position of the rotating column.

[0013] Preferably, the vibration assembly includes a rotating shaft fixedly connected to the output end of a motor, a turntable fixed at one end of the rotating shaft, a fixed shaft eccentrically provided at the other end of the turntable, a lifting component fixed at one end of the fixed shaft, a lifting column rotatably connected to one side of the lifting component, the lifting column being slidably connected to the base, and the outer wall of the lifting column being slidably connected to the abutment rod.

[0015] Preferably, the base has a cavity that moves to accommodate the abutment rod, and a spring is provided between the bottom end of the abutment rod and the protruding position of the inner wall of the main body.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention uses a guide plate that adheres to the inner wall of the main body to form a receiving plate when it is not rotating, avoiding direct impact of gel on the center of the filter plate and preventing the formation of a thick-center, thin-edge accumulation cone. After the material is conveyed, the motor drives the guide plate to rotate through transmission components such as a gear ring and a rotating ring. Centrifugal force is used to overcome the adhesion force and surface tension of the gel, uniformly dividing and conveying the material to the entire area of ​​the filter plate, achieving coverage without dead angles. Through the linkage design of static material receiving and dynamic centrifugal material uniformization of the guide plate, the direct impact of gel on the center of the filter plate to form an accumulation cone is avoided. The guide plates with equal angles evenly distribute the gel into multiple parts and simultaneously convey them to the entire area of ​​the filter plate, achieving coverage without dead angles with consistent material layer thickness. The uniform particle size distribution directly improves the strength of the final dental restoration.

[0018] 2. This invention uses a motor-driven rotating shaft to rotate a turntable. The rotational motion is converted into the vertical reciprocating motion of the lifting column through an eccentric fixed shaft. This, in turn, drives the abutment rod to strike the filter plate, forming a periodic impact. The periodic elastic impact module converts the rotational motion into the vertical reciprocating motion of the abutment rod through mechanical transmission. The instantaneous impact force forms a vibration wave on the surface of the filter plate, which can shake off particles embedded in the screen holes, break the bridging structure, and improve the retention rate of the effective permeable area of ​​the screen holes. The knocking and cleaning action is carried out synchronously with the screening process, eliminating the need for manual cleaning by stopping the machine.

[0019] 3. This invention uses a rotating shaft to drive a threaded rod to rotate, which in turn drives a moving frame to reset and move the guide plate axially. The closed-structure guide plate fits seamlessly with the top of the filter plate, forming a closed compression space. Shear force is used to force out residual gel from the dead corners of the gaps. At the same time, the movement of the guide plate drives the fixed plate to move in tandem. The threaded groove of the fixed column drives the rotating column to rotate, which in turn drives the scraper to rotate and scrape the residual material, redistributing it to the filter plate for screening, thereby achieving material recovery and improving the raw material recovery rate.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 9This invention provides a technical solution: a sieving device for processing dental restorative gel, comprising a main body 1, an opening and closing door 2 on one side of the main body 1 for removing filter residue through the opening and closing door 2, a flow guiding component inside the main body 1, and multiple flow guiding plates 4 arranged at equal angles inside the flow guiding component, so that the gel inside the main body 1 can be evenly distributed by the flow guiding component driving the flow guiding plates 4 to rotate, a fixed plate 5 rotatably connected to one side of the flow guiding plate 4, a sealing ring 6 passing through the flow guiding component, a filter plate 9 at the bottom of the fixed plate 5, a scraping component at the top of the filter plate 9, a scraper 8 fixed at the bottom of the scraping component, the scraper 8 rotating by the scraping component to scrape off the gel remaining on the surface of the filter plate 9, a base 10 symmetrically arranged at the bottom of the filter plate 9, a vibration component inside the base 10, a stop rod 12 fixed at the top of the vibration component, the vibration component driving the stop rod 12 to periodically strike the filter plate 9, a threaded rod 13 connected to one side of the vibration component through a meshing gear set, and a movable frame 14 connected to the outer wall of the threaded rod 13 through threads.

[0034] In practice, after the gel is input into the main body 1, it is first temporarily stored by the non-rotating equal-angle guide plate 4 in the guide assembly to avoid impacting the center of the filter plate 9. Then, the guide assembly drives the guide plate 4 to rotate so that the gel is evenly distributed on the surface of the filter plate 9 to achieve sieving. During the sieving process, the vibration assembly in the base 10 drives the abutment rod 12 to periodically knock on the filter plate 9 to prevent clogging. After sieving, the vibration assembly drives the threaded rod 13 to rotate through the gear set, so that the moving frame 14 drives the guide assembly to reset and fit the guide plate 4 against the inner wall of the main body 1 to form a closed space to squeeze the residual gel. At the same time, the fixed plate 5 is linked to the scraping assembly to drive the scraper 8 to rotate and scrape the residue on the surface and gaps of the filter plate 9 and make it participate in the sieving again. Finally, the filter residue can be taken out through the opening and closing door 2, and the sealing ring 6 prevents the gel from leaking out.

[0035] As a further embodiment of the present invention, the fixing plate 5 is slidably connected to the inner wall of the main body 1, the sealing ring 6 is slidably connected to the cavity opened in the inner wall of the main body 1, and the threaded rod 13 is slidably connected to the inner wall of the main body 1.

[0036] In practice, the fixed plate 5 slides along the inner wall of the main body 1, the sealing ring 6 slides in the cavity opened in the inner wall of the main body 1 to prevent gel leakage, the threaded rod 13 slides with the inner wall of the main body 1, and is driven to rotate by the gear set and drive the moving frame 14 to move, thereby linking the flow guiding component and the scraping component to complete the gel uniformity, residue scraping and other actions, ensuring that the movement of each component is accurate and stable, and adapting to the collaborative needs of screening and cleaning.

[0037] As a further embodiment of the present invention, the flow guiding component includes a gear ring 301 disposed in the interlayer of the main body 1. A gear is meshed on one side of the gear ring 301, and a motor is fixed to one end of the gear. A connecting strip 302 is fixed to the inner wall of the gear ring 301. A rotating ring 303 is fixed to one side of the connecting strip 302. Multiple connecting rods 304 are fixed at equal angles on the outer wall of the rotating ring 303. A rotating component 305 is slidably connected to the connecting rod 304. A fixing rod 306 is fixed to one end of the rotating component 305. The gear ring 301 and the rotating ring 303 are limited to the rotating frame 14.

[0038] In specific implementation, the motor drives the gear to rotate, which in turn drives the gear ring 301 meshing in the interlayer of the main body 1 to rotate. The gear ring 301 drives the rotating ring 303 to rotate synchronously through the connecting strip 302 fixed on the inner wall. The connecting rod 304 fixed at equal angles on the outer wall of the rotating ring 303 slides in the rotating part 305 and drives it to rotate. The rotating part 305 drives the guide plate 4 to rotate through the fixed rod 306 to achieve uniform gel distribution. At the same time, the gear ring 301 and the rotating ring 303 are limited to the rotation of the moving frame 14. When the threaded rod 13 drives the moving frame 14 to move, the guide assembly moves synchronously to complete the action of resetting and squeezing the residual gel of the guide plate 4.

[0039] As a further embodiment of the present invention, the rotating member 305 has a cavity that slides with the connecting rod 304, and the fixed rod 306 is fixedly connected to the guide plate 4.

[0040] In practice, when the rotating ring 303 drives the connecting rod 304 to rotate, the connecting rod 304 slides in the adapting cavity opened in the rotating part 305 and drives the rotating part 305 to rotate synchronously. The fixed rod 306 connected to the rotating part 305 is fixedly connected to the guide plate 4, thereby driving the guide plate 4 to rotate, so as to achieve uniform distribution of gel in the main body 1.

[0041] As a further embodiment of the present invention, the fixing rod 306 penetrates the inner wall of the main body 1, the main body 1 has a cavity that moves in conjunction with the fixing rod 306, and the outer wall of the fixing rod 306 is fixedly connected to the sealing ring 6.

[0042] In specific implementation, the fixed rod 306, which is fixedly connected to the guide plate 4, penetrates the inner wall of the main body 1 and moves within the adaptable cavity opened in the main body 1. At the same time, the outer wall of the fixed rod 306 is fixedly connected to the sealing ring 6. When the fixed rod 306 rotates with the rotating part 305 or moves with the guide assembly, it can synchronously drive the sealing ring 6 to slide on the inner wall of the main body 1, so as to achieve leakage prevention and sealing during the gel screening and cleaning process, and ensure the sealing and stability of the device operation.

[0043] As a further embodiment of the present invention, the scraping component includes a fixed post 701 fixed to the bottom end of the fixed plate 5, and a rotating post 703 slidably connected inside the fixed post 701, and the rotating post 703 is limited to the rotational connection of the filter plate 9.

[0044] In practice, the fixed column 701, which is linked with the fixed plate 5, drives the rotating column 703, which is slidably connected to it, to rotate during the movement. The rotating column 703 and the filter plate 9 are in a limited rotational cooperation, thereby driving the scraper 8 to rotate on the surface of the filter plate 9, so as to scrape off and recycle the residual gel on the surface of the filter plate 9.

[0045] As a further embodiment of the present invention, the outer wall of the rotating column 703 is fixedly connected to the scraper 8, the fixed column 701 has a cavity that moves with the rotating column 703, and the inner wall of the cavity has a threaded groove 702 that moves with the protruding position of the rotating column 703.

[0046] In practice, when the fixed plate 5 moves the fixed column 701, the threaded groove 702 on the inner wall of the cavity of the fixed column 701 matches the protruding position of the rotating column 703, converting the linear movement of the fixed column 701 into the rotational movement of the rotating column 703. The outer wall of the rotating column 703 is fixedly connected to the scraper 8, thereby driving the scraper 8 to rotate on the surface of the filter plate 9, so as to scrape off and evenly disperse the residual gel on the filter plate 9.

[0047] As a further embodiment of the present invention, the vibration assembly includes a rotating shaft 111 fixedly connected to the output end of a motor. One end of the rotating shaft 111 is fixed with a turntable 112, and the other end of the turntable 112 is eccentrically provided with a fixed shaft 113. One end of the fixed shaft 113 is fixed with a lifting member 114. A lifting column 115 is rotatably connected to one side of the lifting member 114. The lifting column 115 is limited and slidably connected to the base 10, and the outer wall of the lifting column 115 is slidably connected to the abutment rod 12.

[0048] In practice, the motor drives the rotating shaft 111, which is fixedly connected to its output end, to rotate. The rotating shaft 111 drives the turntable 112 at one end to rotate synchronously. The fixed shaft 113, which is eccentrically set on the turntable 112, then makes a circular motion, which in turn drives the lifting component 114 at one end to move. The lifting column 115, which is rotatably connected to one side of the lifting component 114, is converted into a vertical reciprocating motion because it is limited and slidably connected to the base 10. The lifting column 115 slides along the inner wall of the abutment rod 12, which ultimately drives the abutment rod 12 to periodically strike the filter plate 9.

[0049] As a further embodiment of the present invention, the abutment rod 12 has a cavity that moves in conjunction with the lifting column 115, and a slide rod 116 is fixed to the inner wall of the cavity. The slide rod 116 passes through the lifting column 115, and a torsion spring 117 is provided between the slide rod 116 and the lifting column 115.

[0050] In practice, when the lifting column 115 slides in the matching cavity opened by the abutment rod 12, the slide rod 116 fixed on the inner wall of the cavity passes through the lifting column 115, and the torsion spring 117 set between the two is stretched with the reciprocating motion of the lifting column 115, thereby buffering the impact force of the lifting column 115's movement and ensuring the stability and regularity of the action of the lifting column 115 driving the abutment rod 12 to strike the filter plate 9.

[0051] As a further embodiment of the present invention, the base 10 has a cavity that moves in conjunction with the abutment rod 12, and a spring 118 is provided between the bottom end of the abutment rod 12 and the protruding position of the inner wall of the main body 1.

[0052] In practice, the abutment rod 12 moves back and forth in the adapting cavity opened in the base 10. When the lifting column 115 drives the abutment rod 12 to move downward and strike the filter plate 9, the spring 118 between the bottom end of the abutment rod 12 and the protruding position of the inner wall of the main body 1 is stretched. After the striking action is completed, the spring 118 releases its elastic force and drives the abutment rod 12 to quickly return to its original position, thereby realizing the periodic striking of the filter plate 9.

[0053] Working principle: When using this screening device for processing dental restoration gel, the gel is fed into the main body 1 through the feed port at the top of the main body 1. At this time, the guide plates 4, which are distributed at equal angles, do not rotate, forming a receiving plate that adheres to the inner wall of the main body 1. The gel fed into the main body 1 first stays at the receiving plate, avoiding the gel from directly impacting the center of the filter plate 9 vertically. After feeding is completed, the motor is started, which drives the gear to rotate, thereby driving the gear ring 301 that meshes with it to rotate. The rotation of the gear ring 301 drives the rotating ring 303 to rotate through the connecting strip 302. When the rotating ring 303 rotates, it synchronously... The connecting rod 304, which is fixed at an angle to the outer wall, rotates. When the connecting rod 304 rotates, it slides in the cavity opened in the rotating part 305 and drives the rotating part 305 to rotate synchronously. The rotating part 305 drives the guide plate 4 to rotate around the fixed plate 5 through the fixed rod 306. When the guide plate 4 rotates, the high viscosity gel that is stationary is subjected to centrifugal force, overcomes its own adhesion force and surface tension, and slides outward along the upper surface of the guide plate 4. Each guide plate 4 becomes an independent material guiding channel, ensuring that the gel is evenly divided into multiple parts and synchronously transported to each area of ​​the filter plate 9 to achieve coverage without dead corners.

[0054] After the gel is filtered through filter plate 9, the motor is started, driving the rotating shaft 111 to rotate, which in turn drives the turntable 112 to rotate. When the turntable 112 rotates, it synchronously drives its eccentrically positioned fixed shaft 113 to rotate. Since the lifting column 115 is limited and slidably connected to the inner wall of the base 10, the lifting component 114 is rotatably connected to the lifting column 115, so that the lifting component 114, which is rotatably connected to the fixed shaft 113, drives the lifting column 115 to reciprocate in the vertical direction. When the lifting column 115 moves, it slides in the cavity opened in the abutment rod 12, and the sliding rod 116 fixed at the bottom end of the abutment rod 12 also slides in the lifting column 115. At this time, the lifting column 115 moves. The torsion spring 117 between the lifting column 115 and the slide rod 116 is stretched. The elastic force released by the torsion spring 117 stabilizes the movement of the lifting column 115 within the abutment rod 12. When the top of the lifting column 115 contacts the bottom of the abutment rod 12, the lifting column 115 continues to move, causing the abutment rod 12 to periodically strike the filter plate 9 (the spring 118 between the abutment rod 12 and the inner wall of the main body 1 is stretched, and the elastic force released by the spring 118 causes the abutment rod 12 to reset). The instantaneous impact force generated by the periodic striking will form a small vibration wave on the surface of the filter plate 9, shaking off the particles embedded in the sieve holes, breaking the bridging structure, and restoring the effective permeability area of ​​the sieve holes.

[0055] When the rotating shaft 111 rotates, the meshing gear set drives the threaded rod 13 to rotate. The rotation of the threaded rod 13 drives the moving frame 14 to move through the threads on its outer wall, which in turn drives the gear ring 301 and the rotating ring 303 to move. When the gear ring 301 and the rotating ring 303 move, the guide plate 4 slides inside the main body 1 (at this time, the guide plate 4 is reset and in the receiving state, and it is in contact with the inner wall of the main body 1). The guide plate 4 has a circular closed structure and fits seamlessly with the top edge of the filter plate 9, forming a closed compression space to prevent residual gel from escaping to other areas during cleaning. At this time, the sealing ring 6 slides in the cavity opened in the inner wall of the main body 1 to prevent gel leakage. When the guide plate 4 moves, the fixing plate 5 moves synchronously, which drives the fixing column 701 to rotate synchronously. The column 701 has a threaded groove 702 that moves in conjunction with the protruding position of the rotating column 703. The rotating column 703 is rotatably connected to the filter plate 9, so that the rotating column 703 is rotated by the movement of the fixed column 701, which in turn drives the scraper 8 to rotate on the surface of the filter plate 9 to scrape off the gel remaining on the surface of the filter plate 9. When the guide plate 4 moves slowly along the axial direction of the top of the filter plate 9, it uses the shearing force generated by the extrusion to break the adhesion between the gel and the surface of the equipment. At the same time, it forces the residual gel embedded in the gaps and dead corners to the effective screening area of ​​the filter plate 9. Meanwhile, the scraper 8 scrapes the extruded residual gel to prevent it from adhering again and evenly disperses the scraped gel to the entire area of ​​the filter plate 9 for re-screening. After the machine stops, the residue at the top of the filter plate 9 can be removed by opening and closing the door 2.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
