Description

Technical Field

[0001] The invention belongs to the technical field of tooth model manufacturing, in particular to a waste collection device for tooth model manufacturing. Background Art

[0002] In the dental model manufacturing process, 3D printing (such as light curing / SLA) or CNC cutting technology is often used to process resin, gypsum, metal and other materials. These processes will generate a large amount of waste, including wet uncured resin, cutting debris and dust, which need to be efficiently recovered and processed through waste collection devices to keep the working environment clean and avoid material waste. In the waste recycling process, most of the time, integrated filters and dust collection ducts are used to achieve rapid recycling. However, 90% of the dust generated by dental model processing (such as zirconia cutting and gypsum polishing) has a particle size of <10μm, of which PM2.5 accounts for more than 30%, far exceeding the hazard level of ordinary industrial dust. Therefore, medical-grade protection is required through filters to avoid causing occupational asthma in operators (resin dust sensitization) and corrosion of precision equipment circuit boards (gypsum dust is hygroscopic and conductive).

[0003] For example, utility model publication number CN218573842U discloses an integrated tooth grinding machine, comprising a feeding mechanism, a rotating mechanism, a crushing mechanism, a container A, and a housing. The machine features a feeding mechanism mounted on the upper end of the housing, a rotating mechanism mounted on the lower end, the crushing mechanism and container A mounted on the rotating mechanism, and a hinged door attached to the housing. This machine performs primary crushing and secondary grading and screening, with particle size controlled by the rotation speed and the distance between the blade and the inner wall of container B. This results in a high yield, high throughput, short processing time, low cost, and the avoidance of cross-contamination.

[0004] However, in existing waste recycling devices, when recycling through pipes, wet waste (such as uncured resin) is easy to adhere to the pipes, causing blockage. In the light-curing 3D printing process, the incompletely cured resin has a high viscosity and is easy to adhere to the inner wall of the collection pipe during the negative pressure suction process. As the waste accumulates, the cross-sectional area of the pipe flow gradually decreases, resulting in increased airflow resistance, decreased suction, and even complete blockage. Traditional solutions usually use manual disassembly and cleaning or high-pressure airflow backblowing, but the operation is cumbersome and cannot achieve continuous operation, seriously affecting production efficiency; on the other hand, when cutting or polishing tooth models, the plaster, metal or resin dust particles generated are small and can easily penetrate ordinary filters or quickly accumulate on their surface, causing filter blockage. Some existing devices use multi-layer filters or regularly replace filter elements to alleviate blockage, but the filter maintenance cost is high, and frequent shutdowns for replacement affect the continuous operation of the equipment and endanger the health of operators.

[0005] Therefore, a waste collection device for tooth model manufacturing is proposed to solve the problems raised in the background art. Summary of the Invention

[0013] Preferably, the scraper is triangular in shape on one side close to the inner wall of the dust suction pipe, and a driving block is fixedly provided on the top of the scraper on one side.

[0014] Preferably, an extrusion block is provided at the bottom of the protrusion, a fixed spring is fixedly installed on one side of the extrusion block, the fixed spring is fixedly connected to the inner wall of the dust suction pipe, and the extrusion block and the fixed spring are both located inside the slide.

[0015] Preferably, the side of the extrusion block away from the protrusion abuts against the driving block, and the sides of the protrusion, the driving block and the extrusion block that are in contact are all in the shape of an inclined surface.

[0016] Preferably, a connecting rod is fixedly provided on the top of the side of the filter close to the diversion pipe, a limiting plate is fixedly provided on the top of the connecting rod, a telescopic spring is fixedly installed on the top of the limiting plate, a limiting box is fixedly provided on the inner wall of the dust suction pipe, and the limiting plate and the telescopic spring are located inside the limit box.

[0017] Preferably, an anti-blocking mechanism is provided on the support plate, and the anti-blocking mechanism is used to prevent the shunt pipe from being blocked.

[0018] Preferably, the anti-blocking mechanism includes two knocking blocks located on both sides symmetrically outside the shunt pipe, a rotating shaft hinged on the knocking blocks, a protruding rod fixedly arranged on the knocking blocks, a fixing frame fixedly arranged on the rotating shaft, and a cam fixedly arranged on the fixing frame, the cam abuts against the protruding rod and drives the protruding rod to rotate in an angle, two pulleys are fixedly arranged on one side of the fixing frame, a belt is sleeved on the pulley, and an adjusting motor is fixedly arranged on one side of the pulley.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention facilitates the filtration, separation and collection of impurities by arranging the coordination of structures such as a dust suction pipe, a diversion pipe, a filter screen and a cleaning component, thereby avoiding the problem of pipe blockage. The fixed tooth model is covered with a dust cover made of transparent acrylic material, so that the polishing status can be observed in real time and debris can be prevented from splashing. At the same time, in conjunction with the dust suction mechanism, a suction pump is used to suck the dust in the cover through the dust suction pipe. After being filtered by the filter screen with an inclined surface, larger particles of impurities enter the diversion pipe under the action of gravity and the cleaning component, effectively reducing the risk of pipe blockage and achieving efficient dust removal. It solves the problem that the resin that is not fully solidified in the existing waste collection device has high viscosity during use and is easy to adhere to the inner wall of the collection pipe during the negative pressure suction process. As the waste accumulates, the flow cross-sectional area of the pipe gradually decreases, resulting in increased airflow resistance, decreased suction, and even complete blockage.

[0021] The present invention facilitates the vibration of the filter screen by arranging the cooperation of structures such as the scraper, the extrusion block and the fixed spring, thereby facilitating the subsequent diversion. The scraper is driven to rotate by the motor, and the filter screen is driven to vibrate while cleaning the inner wall of the dust collection tube, thereby achieving efficient impurity removal. When the scraper rotates, the driving block thereon intermittently squeezes the protrusion, causing the filter screen to vibrate up and down under the action of the spring, prompting impurities to slide into the diversion tube along the inclined surface for discharge. This linkage design can not only scrape off the residue on the inner wall of the tube, but also screen the impurities on the filter screen through vibration, thus avoiding blockage and improving dust removal efficiency.

[0022] The present invention facilitates the prevention of blockage of the shunt pipe by arranging the cooperation of structures such as a knocking block, a protruding rod and a cam. Through the motor-driven cam-knocking block linkage, a continuous and stable anti-blocking effect is achieved through precise mechanical cooperation. When the motor drives the cam to rotate, the special contour of the cam will periodically interact with the protruding rod: when it is at the corresponding position of the cam recess, the knocking block naturally falls down with the help of gravity, and produces a powerful knock on the outer wall of the shunt pipe; and when the cam protrusion rotates into place, it will push the protruding rod to drive the knocking block back to its position. This cyclical mechanical movement forms a stable knocking frequency, so that the shunt pipe always maintains a moderate vibration state. On the one hand, mechanical vibration effectively prevents the adhesion and accumulation of sticky impurities. On the other hand, continuous dynamic knocking can timely shake off the deposited impurity particles. The double guarantee ensures that the shunt pipe always remains in a smooth state. This design is not only simple and reliable in structure, but also has a significant anti-blocking effect, which greatly improves the operating stability and maintenance convenience of the entire device, and has outstanding practical value and technological advancement.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] like Figures 1 to 9 As shown, the present invention provides a waste collection device for tooth model manufacturing, comprising a work box 1, a connecting base 11 fixedly mounted on the top of the work box 1, a collection box 12 slidably mounted inside the work box 1, a support plate 13 fixedly mounted inside the work box 1, a grinding head 2 fixedly mounted at the bottom of the connecting base 11, a fixing fixture 3 mounted at the top center of the work box 1, and a dust cover 4 connected to the outside of the fixing fixture 3. The grinding head 2 is used to grind the tooth model, and the fixing fixture 3 is used to quickly fix the tooth model to be processed;

[0035] The dust collection mechanism 5 is located inside the working box 1 and at the bottom of the grinding head 2. The dust collection mechanism 5 is used to recover dust generated by grinding;

[0036] The dust collection mechanism 5 includes a dust collection pipe 51 fixedly arranged at the top center of the work box 1, a suction pump 52 fixedly mounted on the dust collection pipe 51 and fixedly connected to the work box 1, a diverter pipe 53 fixedly arranged on one side of the dust collection pipe 51, a filter 54 arranged inside the dust collection pipe 51, and a cleaning assembly 55 located inside the dust collection pipe 51;

[0037] The dust suction pipe 51 is connected to the diversion pipe 53. A slide 511 and a support plate 512 are fixedly provided on the inner wall of the dust suction pipe 51. The support plate 512 is annular and is used to support the filter 54. The cross-section of the filter 54 is inclined. A rubber ring 541 is fixedly provided on the outer wall of the filter 54. The rubber ring 541 is in contact with the dust suction pipe 51. The side of the rubber ring 541 away from the diversion pipe 53 is hinged to the dust suction pipe 51. The bottom of the filter 54 is in contact with the support plate 512. A protrusion 542 is fixedly provided on the side of the bottom of the filter 54 close to the diversion pipe 53.

[0038] The above scheme is adopted: the tooth model to be processed is quickly fixed by using the fixing fixture 3, and after the fixation is completed, the grinding head 2 on the connecting seat 11 is moved downward to make it close to the tooth model. At this time, the dust cover 4 is manually covered on the fixed tooth model. Since the dust cover 4 is made of transparent acrylic material, the internal grinding status can be monitored in real time during the processing and grinding of the tooth model, and at the same time, the impurities and debris generated by the grinding are prevented from splashing out. In the process of using the dust cover 4 to prevent dust, the dust suction mechanism 5 can be used at the same time to achieve rapid adsorption and filtration of internal dust. Specifically, the dust inside the dust cover 4 is sucked along the dust suction pipe 51 by using the suction pump 52, and the dust is filtered through the filter 54 on the dust suction pipe 51. After filtering, impurities with high viscosity or large particles will remain on the filter 54. Since the filter 54 is designed with an inclined surface, it can cooperate with the cleaning component 55 and the gravity of the impurities themselves to guide them into the inside of the diversion pipe 53 for diversion, avoiding the problem of easier blockage through a single pipe and reducing the probability of blockage.

[0039] like Figures 3 and 4As shown, the cleaning assembly 55 includes two scrapers 551, a driving rod 552 fixedly arranged at the center of the two scrapers 551, a mounting bracket 553 fixedly mounted on the driving rod 552, and a control motor 554 fixedly mounted on the mounting bracket 553. The mounting bracket 553 is fixedly connected to the inner wall of the dust suction pipe 51. The control motor 554 is used to drive the driving rod 552 to rotate. The side of the scraper 551 close to the inner wall of the dust suction pipe 51 is triangular in shape. A driving block 5511 is fixedly arranged on the top of one side of the scraper 551, and an extrusion block 555 is arranged at the bottom of the protrusion 542. A fixing spring 556 is fixedly mounted on one side of the extrusion block 555. The fixing spring 556 is fixed on the other side of the extrusion block 555. 56 is fixedly connected to the inner wall of the dust suction pipe 51, the extrusion block 555 and the fixed spring 556 are both located inside the slide 511, the extrusion block 555 is in contact with the driving block 5511 on the side away from the protrusion 542, and the side of the protrusion 542 and the driving block 5511 in contact with the extrusion block 555 are all inclined, and a connecting rod 557 is fixedly provided on the top of the side of the filter screen 54 close to the diversion pipe 53, and a limiting plate 558 is fixedly provided on the top of the connecting rod 557, and a telescopic spring 559 is fixedly installed on the top of the limiting plate 558. A limiting box 510 is fixedly provided on the inner wall of the dust suction pipe 51, and the limiting plate 558 and the telescopic spring 559 are located inside the limit box 510.

[0040] The above scheme is adopted: the inner wall of the dust suction pipe 51 is quickly cleaned by the cleaning component 55, and the filter screen 54 is driven to vibrate, so that the impurities inside the filter screen 54 are vibrated and screened out, so that they are quickly discharged into the diversion pipe 53. Specifically, the driving rod 552 is driven to rotate by the control motor 554, and the scrapers 551 on both sides are driven to rotate during the rotation, so that the triangular side of the scraper 551 contacts the inner wall of the dust suction pipe 51, and then the impurities on the inner wall of the dust suction pipe 51 are quickly scraped off. At the same time, the driving block 5511 is driven to rotate synchronously. When the driving block 5511 rotates to the side close to the extrusion block 555, the extrusion block 555 is squeezed to make it close to the protrusion 542. Since the protrusion 542 is limited by the connecting rod 557, the limit plate 558 and the limit box 510, When the drive block 551 is rotated to the side away from the extrusion block 555, the extrusion block 555 loses the extrusion force. At this time, the fixed spring 556 drives the extrusion block 555 to return to its original position and move inside the slide 511, thereby making the extrusion block 555 away from the protrusion 542. The protrusion 542 is reset by its own gravity and the action of the telescopic spring 559, causing the filter 54 to move down and abut against the support plate 512. This cycle repeats. During the rotation of the scraper 551, the filter 54 will be driven to vibrate, and the impurities will be transferred along its slope to the diversion pipe 53 for diversion and discharge.

[0041] like Figure 9As shown, an anti-blocking mechanism 6 is provided on the support plate 13, and the anti-blocking mechanism 6 is used to prevent the diverter pipe 53 from being blocked;

[0042] The anti-blocking mechanism 6 includes two knocking blocks 61 located on both sides symmetrically of the outside of the diversion pipe 53, a rotating shaft 62 hinged on the knocking block 61, a protruding rod 63 fixedly set on the knocking block 61, a fixing frame 65 fixedly set on the rotating shaft 62, and a cam 64 fixedly set on the fixing frame 65. The cam 64 abuts against the protruding rod 63 and drives the protruding rod 63 to rotate. Two pulleys 66 are fixedly set on one side of the fixing frame 65. A belt 67 is sleeved on the pulley 66, and an adjusting motor 68 is fixedly set on one side of the pulley 66.

[0043] The above scheme is adopted: by utilizing the anti-blocking mechanism 6 to knock on the diverter pipe 53, thereby causing the diverter pipe 53 to vibrate, thereby preventing impurities with high viscosity from adhering to the inner wall of the diverter pipe 53 and being difficult to clean, thereby causing the diverter pipe 53 to be blocked. Specifically, by utilizing the adjusting motor 68 to drive the pulley 66 to rotate, the power is transmitted to the pulleys 66 on both sides through the belt 67, thereby driving the two cams 64 to rotate. When the concave side of the cam 64 approaches the protruding rod 63, the knocking block 61 is acted upon by its own gravity to approach the diverter pipe 53 and knock on it. When the protruding side of the cam 64 approaches the protruding rod 63, it will drive the protruding rod 63 to rotate, thereby driving the knocking block 61 away from the diverter pipe 53, thereby realizing continuous knocking on the diverter pipe 53 in a cycle to prevent the diverter pipe 53 from being blocked.

[0044] The working principle and usage process of the present invention: When using the device, the tooth model to be processed can be quickly fixed by using the fixing clamp 3. After fixation, the grinding head 2 and the dust cover 4 are used in combination to achieve dust-free grinding of the tooth model. The dust generated by the processing will fall into the interior of the dust cover 4 and be quickly collected by the adsorption of the suction pump 52 and the dust suction pipe 51. During the collection process, the ground impurities are filtered through the filter 54, and the size and viscosity of the impurities are screened. The lighter impurities enter the bottom dust suction pipe 51 for discharge, and the remaining impurities remain in the filter 54. The cleaning component 55 cleans the inner wall of the dust suction pipe 51 while intermittently vibrating the filter 54, and the impurities inside it are introduced into the diversion pipe 53 for diversion and discharge. When the impurities enter the diversion pipe 53, the anti-blocking mechanism 6 is used to knock the diversion pipe 53 to avoid blockage of the diversion pipe 53, thereby realizing the collection of tooth model processing waste.
