Description

Technical Field

[0001] The invention relates to the technical field of dental stick manufacturing, in particular to automatic dental stick manufacturing equipment. Background Art

[0002] In the traditional production process of dental sticks, the gluing process of the end of the dental stick is one of the key steps, and in order to ensure the firmness of the glue, the end grinding process before gluing is crucial. The traditional end grinding process is usually carried out manually or semi-automatically, which has many shortcomings and limitations, seriously affecting production efficiency and product quality.

[0003] First, in the prior art, the grinding process mainly relies on manual operation, and workers need to manually place the dental sticks one by one on the grinder for grinding. This method is not only labor-intensive, but also due to the influence of human factors, the grinding effect is easily inconsistent, resulting in uneven surface roughness of the end of the dental stick, affecting the adhesion effect of the adhesive. If the grinding is not sufficient, the glue cannot be evenly applied to the end of the dental stick, causing glue leakage or insufficient adhesion, affecting the strength and service life of the final product; and excessive grinding may damage the dental stick, resulting in material waste and increased scrap rate.

[0004] Secondly, traditional equipment lacks precise clamping and positioning devices during the grinding process. The dental rod is prone to shifting or shaking during grinding, resulting in an unstable grinding position, which further affects the grinding accuracy. Due to inaccurate positioning of the rod or insufficient clamping force, the workpiece is prone to offset during high-speed grinding, resulting in an irregular grinding surface, which not only affects the aesthetics of the product, but also makes it difficult to evenly cover the glue in the subsequent gluing process, ultimately affecting the performance of the dental rod. In addition, the offset of the rod may cause uneven wear of the grinding head, accelerate equipment loss, and increase maintenance costs.

[0005] Finally, most traditional dental rod grinding equipment has a low degree of automation and cannot achieve multi-station synchronous grinding and automatic rod transfer. Workers need to manually place each dental rod in the equipment for grinding, and manually remove the rod after grinding before proceeding to the next step. This operation method is not only inefficient, but also prone to grinding omissions or rod accumulation, which increases production time and increases the difficulty of operation. At the same time, traditional equipment is prone to generate a large amount of debris and dust during grinding. These waste materials not only pollute the working environment, but also require frequent shutdowns for cleaning, which increases non-working time of production and further reduces production efficiency.

[0006] In view of this, research and improvement are carried out on the existing problems, and an automatic manufacturing equipment for dental rods is provided to solve the current problems. The purpose is to solve the problems and improve the practical value through this technology. Summary of the invention

[0035] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0036] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0037] An automatic dental stick manufacturing device provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0038] Combination Figure 1-Figure 7 As shown, the present invention provides an automatic dental rod manufacturing device, comprising: a rod feeding mechanism 100, a grinding head driving mechanism 200, a grinding head mechanism 300 and a pneumatic discharger 400, wherein the rod feeding mechanism 100 comprises a vibrating material tray 110, a linear feeder 120, a pusher 130 and a material guide assembly 140. The output end of the vibrating material tray 110 is connected to one end of the linear feeder 120, and is used to sort the material rods and transmit them one by one; the pusher 130 and the material guide assembly 140 are used to accurately push the material rods into the interior of the grinding head mechanism 300.

[0039] Specifically, when the bar material feeding mechanism 100 is working, the material inside the vibrating material tray 110 gradually enters the linear feeder 120 under the action of vibration, and the material rods are transmitted through the linear vibration of the linear feeder 120, so that the material rods enter the inner side of the material groove 144 on the surface of the material receiving seat 143 one by one. When one of the material grooves 144 is completed at the end of the linear feeder 120, the control rod 142 pushes the material receiving seat 143 to slide, so that the other material groove 144 is aligned with the end of the linear feeder 120 to receive the material, so that the surface of the material receiving seat 143 can synchronously receive two material rods, which significantly improves the transmission efficiency of the material rods. After receiving, on the surface of the positioning frame 210, the rotating material tray 230 driven by the indexing motor 220 accurately indexes and rotates, so that the two grinding head mechanisms 300 on the surface of the rotating material tray 230 are accurately aligned with the two material grooves 144. Driven by the pusher 130 , the pusher head 131 fixed at the output end thereof pushes the material rods in the material trough 144 into the corresponding grinding head mechanism 300 , thereby completing the material rod supply operation.

[0040] In this process, the grinding head driving mechanism 200 includes a positioning frame 210, a dividing motor 220, and a rotating material disc 230 rotatably mounted on one side of the positioning frame 210. A driving motor 240 is fixedly mounted on the surface of the positioning frame 210, and the dividing motor 220 is fixedly mounted on one side of the positioning frame 210, and its output end is fixedly connected to the surface of the rotating material disc 230, and is used to drive the rotating material disc 230 to rotate. At the same time, a push rod seat 250 is fixedly mounted on the top surface of the positioning frame 210, and a finger clamping cylinder 251 is fixedly connected to the output end of the push rod seat 250, and a clamping rod adapted to the surface of the grinding head mechanism 300 is provided at the output end of the finger clamping cylinder 251.

[0041] When the indexing motor 220 drives the rotating material disc 230 to rotate, the grinding head mechanism 300 and the material trough 144 can be precisely aligned. The push rod seat 250 controls the finger clamping cylinder 251 to retreat and sleeve on the surfaces of the two grinding head mechanisms 300. When the material rod enters the inside of the grinding head mechanism 300, the finger clamping cylinder 251 clamps the clamping disc 330 on the surface of the grinding head mechanism 300. This not only ensures that the position of the rotating material disc 230 and the grinding head mechanism 300 is locked, and prevents the rotating material disc 230 from shifting when the driving motor 240 is working, but also causes the flexible clamping disc 330 to deform, thereby stably clamping the material rod inside.

[0042] Next, driven by the driving motor 240, the grinding cylinder 320 is driven to rotate relative to the rotating bearing seat 310 and the clamping plate 330 through the transmission gear 321, and the grinding surface located on the inner side of the grinding head hole 322 is used to grind the end of the material rod clamped in the clamping plate 330, so that its surface is rough, which is convenient for the subsequent gluing operation. After the end of the material rod is polished, the equipment can automatically repeat the above operation. The push rod seat 250 drives the clamping finger cylinder 251 to release the clamping lock of the grinding head mechanism 300, and the indexing motor 220 drives the rotating material plate 230 to rotate, driving the grinding head mechanism 300 on the surface to switch to the next group of material rods to continue operation.

[0043] When the grinding head mechanism 300 on the surface of the rotating disc 230 rotates to the port of the pneumatic discharger 400, the nozzle on the surface of the pneumatic discharger 400 is aimed at the inner side of the grinding head mechanism 300 to pump high-pressure airflow into the inner section of the grinding cylinder 320, thereby blowing out the material rods and debris generated by grinding inside the grinding cylinder 320 and the clamping disc 330, and making them enter the inside of the receiving hopper 410, completing the automatic unloading operation after the end of the material rod is ground.

[0044] In another embodiment of the present invention, the material guide assembly 140 includes a guide seat 141, a control rod 142, and a material receiving seat 143 slidably mounted on the surface of the guide seat 141. The control rod 142 is fixed to one side of the guide seat 141, and is used to control the translational sliding of the material receiving seat 143. Two material troughs 144 are provided on the surface of the material receiving seat 143, and a pusher head 131 is fixedly mounted at the output end of the pusher 130, and is used to push the pusher head 131 along the arrangement direction of the material trough 144, and the material rod inside the material trough 144 is sent into the grinding head mechanism 300 through the movement of the pusher head 131.

[0045] Specifically, the linear feeder 120 transmits the material bars through linear vibration, so that they enter the material slots 144 on the surface of the receiving seat 143 one by one. When one of the material slots 144 completes receiving the material at the end of the linear feeder 120, the control rod 142 pushes the receiving seat 143 to slide, so that the other material slot 144 is aligned with the end of the linear feeder 120, so that the surface of the receiving seat 143 can receive two material bars at the same time, which greatly improves the processing efficiency.

[0046] In another embodiment, a material sensor is provided on the surface of the material guide assembly 140 for detecting the filling state of the bar material inside the material trough 144. The output end of the material sensor is electrically connected to the control system, and the output end of the control system is electrically connected to the input end of the pusher 130, the grinding head drive mechanism 200 and the pneumatic discharger 400, thereby realizing the coordinated control of the working sequence of the pusher 130, the grinding head drive mechanism 200 and the pneumatic discharger 400.

[0047] In a further embodiment of the present invention, the push rod seat 250 is a push rod cylinder structure, and its driving direction is perpendicular to the surface of the rotating material plate 230, and the clamping finger cylinder 251 is a clamping finger cylinder structure, which is used to control the clamping operation of the clamping head rod on the surface of the clamping plate 330. The clamping plate 330 is a silicone material component, and a sleeve hole for sleeve-connecting the material rod is provided on its inner side, and one end of the sleeve hole is connected to the grinding head hole 322.

[0048] Specifically, the push rod seat 250 controls the finger clamping cylinder 251 to retract, and is sleeved on the surfaces of the two grinding head mechanisms 300. After the material rod enters the interior of the grinding head mechanism 300, the clamping plate 330 on the surface of the grinding head mechanism 300 is clamped, so that the flexible clamping plate 330 is deformed, thereby firmly clamping the internal material rod.

[0049] In another embodiment, the grinding head hole 322 is a conical hole structure, and its inner side is a frosted surface structure, which is mainly used for grinding the end of the material rod. At the same time, an air pump and a compressor are provided on the inner side of the pneumatic discharger 400, which are responsible for outputting high-speed jet airflow. The nozzles on the surface of the pneumatic discharger 400 are arranged in an arc shape, and are arranged in the same manner as the grinding head mechanism 300. Specifically, when the rotating disk 230 drives the grinding head mechanism 300 to rotate to the nozzle of the pneumatic discharger 400, the high-pressure airflow output through the nozzle can effectively blow out the material rod and grinding debris inside the grinding head mechanism 300, thereby realizing automatic unloading of the material rod end.

[0050] In another embodiment, a surface of the hopper 410 is provided with a plurality of evenly distributed sieve holes for screening the material rods and the debris generated by grinding, thereby further optimizing the efficiency of the production process.

[0051] The working principle and use process of the present invention:

[0052] When the rod material feeding mechanism 100 is working, the material inside the vibrating material tray 110 enters the linear feeder 120 under the action of vibration, and the material rods are transmitted through the linear vibration of the linear feeder 120, so that they enter the inner side of the material groove 144 on the surface of the material receiving seat 143 one by one. When one of the material grooves 144 has completed receiving the material at the end of the linear feeder 120, the control rod 142 pushes the material receiving seat 143 to slide, so that the other material groove 144 is aligned with the end of the linear feeder 120 to receive the material, so that the surface of the material receiving seat 143 receives two material rods synchronously, and the indexing motor 220 on the surface of the positioning frame 210 drives the rotating material tray 230 to rotate accurately, so that the two grinding head mechanisms 300 on the surface are accurately aligned with the two material grooves 144, and the pusher head 131 driven by the pusher 130 pushes the material rods inside the material groove 144 into the corresponding grinding head mechanism 300 to complete the feeding;

[0053] When the indexing motor 220 drives the rotating material disc 230 to rotate, and the grinding head mechanism 300 and the material trough 144 are precisely aligned, the push rod seat 250 controls the clamping cylinder 251 to retreat and sleeve on the surfaces of the two grinding head mechanisms 300, and clamps the clamping disc 330 on the surface of the grinding head mechanism 300 after the material rod enters the inside of the grinding head mechanism 300. On the one hand, the position locking of the rotating material disc 230 and the grinding head mechanism 300 is ensured to prevent the rotating material disc 230 from shifting during the operation of the driving motor 240. On the other hand, the clamping disc 330 is clamped to deform it to clamp and fix the internal material rod. Under the condition that the transmission gear 321 drives the grinding cylinder 320 to rotate relative to the rotating bearing seat 310 and the clamping plate 330, the grinding surface inside the grinding head hole 322 is used to grind the end of the material rod clamped inside the clamping plate 330, so that the end of the material rod has a rough surface, which is convenient for subsequent dental rod production and processing procedures such as gluing; after the end is polished, the above operation is automatically repeated, the push rod seat 250 drives the clamping finger cylinder 251 to disengage the clamping lock of the grinding head mechanism 300, and the indexing motor 220 drives the rotating material plate 230 to rotate, driving the surface grinding head mechanism 300 to move and switch to another group of grinding head mechanisms 300 to receive the material;

[0054] The grinding head mechanism 300 on the surface of the rotating material plate 230 rotates to the port of the pneumatic discharger 400, and the nozzle on the surface of the pneumatic discharger 400 faces the inner side of the grinding head mechanism 300. By pumping high-pressure gas to a section of the grinding cylinder 320, the gas pushes the material rods and grinding debris inside the grinding cylinder 320 and the sandwich plate 330 into the hopper 410, and outputs the material rods with polished ends, completing the entire automated material rod end polishing operation.
