[0027] For a better understanding, Figures 1 to 12 As shown in one embodiment, the present application discloses a soft periodontal plug automatic production line comprising a stirring device, a conveying device and a packaging system, wherein, The stirring device comprises: A stirring barrel 10 containing and stirring soft periodontal plug materials; as known from the background art, the raw materials of the soft periodontal plug include liquid materials and powder materials, and the two types of raw materials described in the present application also correspond to the liquid and powder materials mentioned in the subsequent description of the specific production process; A first motor and a stirring rod 1, the first motor being arranged at the top of the stirring barrel 10, the first motor driving the stirring rod extending into the stirring barrel 10 to rotate, A plurality of wall scraping stirring blades 4 connected to the stirring rod and rotating with the stirring rod to scrape the inner wall of the stirring barrel 10, A plurality of spiral stirring blades 6 connected to the stirring rod and rotating with the stirring rod in the stirring barrel 10, a plurality of horizontal spinning devices 5, which are connected to the stirring rod to spin while the stirring rod rotates in the stirring barrel 10, an infrared spiral heating tube 2, which is fixed to the inner wall of the top of the stirring barrel 10, two feeding pipes 3, which are symmetrically arranged on the side wall of the stirring barrel 10, and each of the top of the feeding pipe 3 is provided with a top cover 13; an ultrasonic vibration plate 14, which is fixed to the inner wall of the top of the stirring barrel 10 through an extension pipe 15; an automatic discharge valve 9, which is arranged at the bottom of the stirring barrel 10 to controllably discharge, a fan-shaped stirring device 7, which is fixed to the automatic discharge valve 9, a refractive index detector 8, which is fixed to the automatic discharge valve 9, and the fan-shaped stirring device 7 is located above the refractive index detector 8; that is, the fan-shaped stirring device is closer to the top of the stirring barrel than the refractive index detector; in essence, the fan-shaped stirring device implements stirring, and the refractive index detector detects the stirring condition in real time; that is, the present application uses the refractive index detector to detect the refractive index change of the stirring material in real time, and different swelling degrees of hydrogel have different refractive indexes to judge the product state; when the refractive index of the stirring material is within the set range for a continuous period of time, it indicates that the material has been fully mixed; the transmission device comprises: a transmission cylinder, which is arranged below the stirring barrel 10 and connected to the automatic discharge valve 9, a spiral transmission blade 11, which is arranged in the transmission cylinder, and the spiral transmission blade 11 is driven to rotate by a second motor 24, a transmission device discharge port 12, which is arranged at one end of the transmission cylinder away from the automatic discharge valve 9; the packaging system comprises: two vertical support rods, two horizontal support rods, which are respectively connected above the vertical support rods, and one end of the horizontal support rod towards the transmission device discharge port 12 is provided with a horizontal extension rod 19, a bidirectional cutting blade 18, which is fixed on the horizontal extension rod, a conveyor belt 25, which extends horizontally between the two vertical support rods and below the two horizontal support rods, a hydraulic packaging device 22, which is connected between the two vertical support rods through two sets of pipes, and the lower end of the hydraulic packaging device 22 is provided with a first blade 23-1 and a second blade 23-2 extending along the conveying direction of the conveyor belt 25, a plurality of porous plastic plates 20, which are sequentially conveyed from front to back on the conveyor belt; a transition roller 21-2, which is fixed above the conveyor belt 25 and below the horizontal extension rod 19, Replaceable aluminum film roller 21-1, which is fixed to the conveyor belt 25 and is located above the transition roller 21-2 and below the horizontal telescopic rod 19, Electric roller 21-3, which is fixed to the conveyor belt 25 and is located behind the vertical support rod, drives the aluminum film on the replaceable aluminum film roller 21-1 to pass through the transition roller 21-2 and reach below the hydraulic packaging device.

[0028] For the above-mentioned embodiments, it can be understood that the refractive index detector detects the change of the refractive index of the stirring material in real time, and the product state is judged according to the different refractive indexes of the hydrogel with different swelling degrees. When the refractive index of the stirring material is within the set range for a continuous period of time, it indicates that the material has been fully mixed. After mixing, the information can be further fed back to the automatic discharge valve to realize the automatic opening and closing of the valve after the stirring is completed, so that the preparation process is more accurate and energy-saving and environmentally friendly, and the unnecessary waste of time and energy caused by the traditional long stirring time is overcome.

[0029] In addition, it can be found that the above-mentioned embodiments essentially adopt a stirring mode combining ultrasonic vibration plate stirring and mechanical stirring, wherein the ultrasonic stirring is especially suitable for liquid materials (such as musk ketone, clove oil, fatty acid, plasticizer, phenolic resin, etc.) in the raw materials of the periodontal plugger; the mechanical stirring, such as the multi-blade used in the above-mentioned embodiments, fully stirs the material from multiple angles, which is especially suitable for the preparation of soft periodontal plugger with soft gel-like material; it can be understood that a hydrophobic layer can be further applied to the surface of the blade to reduce the material wall sticking during stirring. It needs to be specially pointed out that the ultrasonic vibration plate not only has the above-mentioned function of being especially suitable for stirring liquid materials, but also has a complex function itself, typically: after a certain amount of product is produced each time, the relevant parts or devices of the above-mentioned production line are closed, then water or cleaning liquid and other liquids are injected into the inside, and the ultrasonic vibration plate is used again for overall disinfection and cleaning. Ultrasonic cleaning has high precision and is suitable for cleaning various parts, surfaces and deep-seated small dirt.

[0030] In addition, for the production line for preparing the soft periodontal plug in a gel form, the material is heated by radiation in an infrared manner, without direct contact with the material, avoiding the mixing of metal ions into the final soft periodontal plug due to the wear or chemical corrosion of the heating element such as the traditional heating wire, thereby affecting the biocompatibility of the product. In addition, the temperature uniformity of infrared heating is good, which is conducive to reducing the batch difference and improving the swelling degree and adhesion of the soft periodontal plug. Therefore, the production line of the above embodiment is helpful to the biocompatibility, swelling degree, adhesion and other factors related to product control of the soft periodontal plug. In addition, for different raw materials and their stirred mixtures, they have different infrared absorption characteristics. After preliminary test, higher efficient infrared heating can be realized by matching the material absorption peak band, thereby further saving energy and shortening the production cycle. Further, the infrared heating is combined with the refractive index detector to monitor the mixing state of the gel in real time, and based on the closed loop control principle (such as the PID control in the prior art), the automatic control of "heating-stirring-discharging" can be realized.

[0031] In addition, it should be noted that when the final soft periodontal plug is packaged by the packaging device, it is preferred to be packaged as a one-time small specification package, which not only fits the characteristics of less actual use at a time in the clinic, but also reduces the problems of pollution and consumption of the product during use.

[0051] Two horizontal support rods are connected above the vertical support rods. The front ends of the horizontal support rods are connected to two horizontal telescopic rods 19. The bidirectional cutting blade 18 is fixed on the horizontal telescopic rods. The bidirectional cutting blade 18 is located at the same height as the lower end of the discharge port 12 and extends forward and backward with the horizontal telescopic rod 19. When the materials are output from the discharge port 12, they quickly slide through the lower end of the discharge port, cut the materials into a uniform amount, then quickly slide in the opposite direction through the lower end of the discharge port again, cut the materials again, improve the cutting efficiency, and control the materials to a uniform amount. The multi-hole plastic plate 20 is located on the conveying belt and is conveyed from front to back. The hole diameter of the multi-hole plastic plate 20 corresponds to the discharge hole of the discharge port 12. Each hole is intermittently connected and can be separated by force. The finished products produced by the production line are transported in the form of a multi-hole plastic plate in the subsequent process. In the actual clinical use process, the aluminum-sealed multi-hole plastic plate is disassembled into multiple disposable single-hole plastic plate packaging products, which can be used immediately and discarded directly after use, effectively avoiding the dryness, hardness, need for secondary adjustment, and easy waste of existing large jar packaging products in the actual use process.

[0052] In one embodiment, the roller group 21 includes an upper and lower replaceable aluminum film roller 21-1 and a transition roller 21-2. The replaceable aluminum film roller 21-1 and the transition roller 21-2 are fixed on the conveying belt 25 and located in front of the vertical support rods, and the replaceable aluminum film roller is located above the transition roller. The electric roller 21-3 is fixed on the conveying belt 25 and located behind the vertical support rods. The aluminum film cylinder on the replaceable aluminum film roller 21-1 can be disassembled and replaced. The electric roller 21-3 can rotate by itself, driving the aluminum film on the replaceable aluminum film roller to pass through the transition roller 21-2, reach the lower part of the hydraulic encapsulation device, and adhere to the multi-hole plastic plate by pressing. Through sealed storage, the finished product moisture is not lost, does not contact air, and realizes instant use after disassembly.

[0053] In another embodiment, the specific production process of the present application is as follows: liquid (e.g. thymol, clove oil, fatty acid, plasticizer, phenolic resin, etc.) and powder raw materials (e.g. zinc oxide, rosin powder, tannic acid, kaolin, fatty acid metal salt, calcium hydroxide, zinc phosphate, etc.) are respectively added into the stirring barrel 10 from the feeding port 3, and then pass through the ultrasonic vibration plate 14 and the first motor-driven mechanical stirring in sequence, so as to be mixed uniformly, and heated by the infrared spiral heating tube 2 during the mixing process; the refractive index detector 8 detects the refractive index of the mixed material in real time and feeds back information to the automatic discharge valve 9, so that the automatic discharge valve 9 is opened and closed, and the material that has been stirred (i.e. mixed uniformly) is naturally fed into the conveying device; as mentioned above, the present application can detect the change of the refractive index of the stirred material in real time by using the refractive index detector while the raw materials are uniformly stirred and mixed, and the product state is judged according to the different refractive indexes of the hydrogel with different swelling degrees; when the refractive index of the stirred material is within the set range for a continuous period of time, it indicates that the material has been fully mixed; further, the second motor 24 drives the spiral conveying blade 11 to convey the material to the assembly system; the material is uniformly divided into uniform portions by the bidirectional cutting blade 18 and falls into the multi-hole plastic plate 20, and then is conveyed to the hydraulic packaging device 22 by the conveying belt 25, and is pressed and packaged with the aluminum film, and then is conveyed to the subsequent packaging link by the conveying belt 25; the speed of the material output from the discharge port 12, the speed of the bidirectional cutting blade 18, the speed of the conveying belt 25, the speed of the hydraulic packaging device 22 and the speed of the motor roller 21-3 are matched, and the automatic production process is realized by the controller, and further, the controller includes PLC. It can be understood that all movable parts, such as the ultrasonic vibration plate 14, the automatic discharge valve 9, the fan-shaped stirring device 7, the conveying belt 25, etc., and the parts that need to be controlled, such as the infrared spiral heating tube 2, etc., also need to be electrically connected to the controller in a direct or indirect manner and controlled by the controller.

[0054] In another embodiment, when the powder material and the liquid material are added, the liquid material is first added into the stirring barrel 10 through the feeding pipe, the liquid material dominates in the initial stage of stirring, and the ultrasonic stirring mode dominates at this time, and then the powder material is gradually added in the stirring process of the liquid material, and the powder material is gradually dispersed in the liquid material, and further mechanical stirring is enabled - that is, the ultrasonic vibration plate 14 is started only when the powder material is not added, and the fan-shaped stirring device 7 can be temporarily not started, i.e. temporarily not consume energy, and the fan-shaped stirring device 7 is started when the powder material is added. In this way, the energy consumption of stirring can be reduced as much as possible. The bevel gears 17-1 and 17-2 are located in the stirring barrel, and the materials contacted during the operation process are mainly liquid materials and soft gel mixed with powder materials.

[0055] It should be noted that in the present application, the bevel gear transmission has the characteristics of compact structure, stable transmission ratio and high bearing capacity, high-precision transmission, and the surface of the related gear adopts a hydrophobic coating, which reduces the adhesion of viscous materials on its surface by reducing the surface energy, thereby reducing the risk of residue. In addition, the present application has self-cleaning characteristics, because: during the stirring process, the combined motion of the spiral stirring blade 6 and the wall scraping stirring blade 4 forms a centrifugal field, which pushes the material from the center of the stirring barrel to the periphery, and the bevel gear area is in a relatively low shear environment, and the amount of material adhesion is extremely low. In addition, as mentioned earlier, the production line disclosed in the present application needs to be worked for a period of time or produce a certain amount before ultrasonic cleaning. In addition, the first motor drives the stirring rod 1 to rotate, so that the bevel gear 17-1 (i.e. horizontal bevel gear) fixed on the stirring rod 1 is closely engaged with the rotating tooth surface of the bevel gear 17-2 (i.e. vertical bevel gear), further rotating the bevel gear 17-2, and ultimately realizing the revolution + rotation of the horizontal self-rotating device 5 and accompanying the complex motion of stirring in the present application, which not only improves the stirring efficiency, but also helps to reduce the adhesion of viscous materials. Moreover, the soft periodontal plug agent is a hydrogel, which belongs to a shear-thinning non-Newtonian fluid (viscosity decreases with increasing shear rate), and its characteristics are as follows: (1) low shear environment (gear meshing area): the material maintains a high viscosity, poor flowability, and is difficult to penetrate into the bevel gear meshing surface, thereby avoiding jamming; (2) high shear environment (stirring blade area): the material has reduced viscosity and enhanced flowability, which is beneficial to uniform mixing, and in addition, the soft periodontal plug agent has a low elastic modulus as a hydrogel, and its softness also leads to: even if a small amount of material contacts the gear surface, it will be squeezed to a larger gap area due to elastic deformation, thereby unable to form a sustained pressure on the gear meshing surface. More preferably, the assembly relationship between the bevel gear 17-2 and the horizontal self-rotating device 5 is a detachable module. More preferably, the bevel gear 17-1 on the stirring rod 1 can also be detached. Thus, the present application does not need to worry about the material adhering to the bevel gear and affecting the transmission of the bevel gear.
