Description

Technical Field

[0002] Toothpaste is a common oral care product in life, used to protect dental health. In order to improve the effectiveness of toothpaste, merchants generally add toothpaste additives to toothpaste.

[0003] Based on the search for toothpaste flake additives, a Chinese invention patent with an authorization announcement number of CN109846749B was found, which discloses a flake toothpaste additive and a preparation method thereof. The mixture A is obtained by stirring starch, deionized water and hydroxypropyl methylcellulose, and then polyethylene glycol is added and stirred to obtain a mixture B. Then talcum powder, colorant and deionized water are added and ultrasonically dispersed to obtain a mixture C. Then sodium lauryl sulfate and methylparaben are added and dissolved in deionized water and slowly added to the mixture C. After stirring evenly, the mixture is dried and sliced ​​to obtain a flake toothpaste additive. In the preparation method, quantitative addition and sufficient mixing of raw materials are one of the factors affecting the quality of the final additive.

The inert gas blown out through the connecting channel can give the raw material passing through the notch a constant initial horizontal velocity in the horizontal direction; The above two are combined: 1. On the one hand, the horizontal displacement of the raw materials can be different, so that the raw materials can fall into the mixing tank more evenly. On the other hand, when the raw materials contact the raw materials previously put into the mixing tank, the vertical speed is different. Therefore, the depth of the raw materials into the raw materials previously put into the mixing tank is different, so that the raw materials can be more evenly penetrated into the raw materials previously put into the mixing tank.

DETAILED DESCRIPTION

[0019] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0020] An oral care additive, which can be referred to the existing patent documents mentioned in the background technology, is not the core of this solution and will not be described in detail.

[0021] Reference Figure 1-Figure 8A feeding device for the production of oral care additives includes a frame 100, on which a conveyor belt 101 and a feeding member 200 are arranged, wherein the conveying direction of the conveyor belt 101 is horizontally arranged, the feeding member 200 is located directly above the conveyor belt 101, and a plurality of feeding members 200 are arranged in an array along the conveying direction of the conveyor belt 101, and the height of the output end of the feeding member 200 increases successively along the conveying direction. A drying structure is also provided on the frame 100 for performing hot air blowing and drying treatment on the oral care additives on the conveyor belt 101, and the existing electric heating technology and the fan technology can be used to form hot air for drying, which will not be elaborated.

[0022] It should be noted that in this solution, the oral care additive is produced by stacking layers of materials, and each layer of materials is made by fully mixing and stirring multiple raw materials. For example, the first layer of materials is a mixture of film formers, fillers, and pigments, and the second layer of materials is a mixture of film formers, fillers, and flavors; During production, different feeding members 200 are used to stir the raw materials to obtain different layers of materials. Then, a layer of film is laid on the conveyor belt 101. The conveyor belt 101 pulls the film to move. During the movement, the first layer of material is laid on the film by the first group of feeding members 200 and dried by hot air. Then, the second layer of material is laid on the dried first layer of material by the second group of feeding members 200. This process is repeated to obtain the oral care additive. Finally, the oral care additive can be cut into a desired shape. It should be noted that in order to ensure the adhesion between two adjacent layers of materials, the two adjacent layers of materials can be bonded together by adhesives; It should be noted that hot air drying, material conveying, bonding and other technologies are not the core of this solution. Existing technologies can be used and will not be elaborated on. One of the cores of this solution is to quantitatively weigh the raw materials and mix them thoroughly to obtain each layer of material.

[0023] The feeding component 200 includes a mixing component and an output component. The former is used to quantitatively weigh the raw materials and fully mix the raw materials to obtain each layer of material, and the latter is used to lay the mixed material on the film or the previous layer of material.

[0024] 1. Hybrid Components Reference Figure 2-Figure 8 The mixing assembly includes a mixing tank 205, the upper tank opening of the mixing tank 205 is provided with a tank cover 2051, the tank bottom is arranged in a truncated cone shape with a diameter increasing from bottom to top, and the bottom of the tank bottom is provided with a bottom pipe 2052.

[0025] A stirring shaft 2053 is coaxially arranged in the mixing tank 205, and the lower end of the stirring shaft 2053 extends out of the mixing tank 205 and forms a power connection with the first motor 218 arranged on the frame 100. The stirring shaft 2053 can be driven to rotate by the first motor 218, and the stirring shaft 2053 rotates together with the stirring blades 2054 to achieve stirring of the raw materials in the mixing tank 205. Furthermore, an auxiliary auger 2055 is also arranged on the outside of the stirring shaft 2053. The auxiliary auger 2055 is located in the bottom tube 2052 and the upper end extends into the mixing tank 205. During stirring, the rotation of the auxiliary auger 2055 can pull the raw materials in the bottom tube 2052 to move upward, thereby preventing the raw materials in the bottom tube 2052 from not participating in the stirring and affecting the stirring effect, thereby playing a role of auxiliary stirring. After the stirring is completed, the auxiliary auger 2055 rotates in the opposite direction to pull the mixed materials to be output outward, thereby playing a role of auxiliary output.

[0026] The mixing assembly also includes a quantitative feeding component disposed on the tank cover 2051 .

[0027] A fixing hole is coaxially opened on the tank cover 2051, and the quantitative feeding component includes a fixing sleeve 210 coaxially arranged at the lower opening of the fixing hole, and a bottom cover 2101 is arranged at the lower opening of the fixing sleeve 210, and a notch 2102 and a nozzle 2103 are arranged on the bottom cover 2101. A feeding pipe is arranged at the end of the nozzle 2103, and the end of the feeding pipe extends out of the mixing tank 205 and is connected to the discharge end of the peristaltic pump 206. The feeding end of the peristaltic pump 206 is used for receiving raw materials. The peristaltic pump 206 can be arranged on the frame 100 or the tank cover 2051.

[0028] A movable sleeve in the fixed sleeve 210 is provided with a rotating body 214, the upper end of the rotating body 214 extends out of the fixed sleeve 210 and forms a power connection with the second motor 209. The rotating body 214 can be driven to rotate by the second motor 209. The second motor 209 can be set on the frame 100 or the tank cover 2051.

[0029] An air hole 2141 and a material storage hole 2142 are provided on the end surface of the rotating body 214, wherein the air hole 2141 is coaxial with the rotating body 214, and an air inlet pipe 213 is provided at the upper opening of the air hole 2141, and a connection is achieved between the lower opening of the air hole 2141 and the notch 2102 via a connecting channel, and the connecting channel is provided on the upper surface of the bottom cover 2101, and a connecting air pipe is provided at the end of the air inlet pipe 213 via a rotating joint, and the end of the connecting air pipe is connected to a gas tank 208 storing inert protective gas, and a solenoid valve is provided on the connecting air pipe, and the gas tank 208 is in a positive pressure state, therefore, when the solenoid valve is opened, the inert protective gas can be output through the connecting air pipe, the rotating joint, the air inlet pipe 213, the air hole 2141 and the connecting channel, and the gas during output is blown horizontally toward the lower surface of the rotating body 214 at the notch 2102.

[0030] During the rotation of the rotating body 214, the lower opening of the material storage hole 2142 can be completely connected with the notch 2102, and the material storage hole 2142 can be connected with the nozzle 2103. There are at least two material storage holes 2142 arranged in an array along the circumferential direction of the rotating body 214, and each material storage hole 2142 is provided with a quantitative feeding unit.

[0031] The quantitative feeding unit includes a threaded shaft 212 and a piston 215 sleeved in the material storage hole 2142 , and a piston rod 216 is provided on the upper end surface of the piston 215 .

[0032] The threaded shaft 212 is in the shape of a hollow shaft coaxial with the material storage hole 2142. The lower end of the threaded shaft 212 extends into the material storage hole 2142. The threaded shaft 212 is sleeved on the outside of the piston rod 216. The lower end of the threaded shaft 212 is provided with a built-in step, and the upper end of the piston rod 216 is provided with a nut. Initially, the built-in step supports the nut and the lower surface of the piston 215 is flush with the lower hole opening of the material storage hole 2142.

[0033] A fixing cover is disposed on the upper surface of the rotating body 214 . The fixing cover is provided with an escape hole for escaping the threaded shaft 212 . A spring 217 is disposed between the piston 215 and the fixing cover.

[0034] A sliding connection is formed between the threaded shaft 212 and the fixed cover in the vertical direction. The threaded shaft 212 and the third motor 211 are powered by a power transmission component. The third motor 211 is arranged on the fixed cover. The driven member of the power transmission component is threadedly sleeved on the outside of the threaded shaft 212. A limit bracket is provided on the fixed cover for limiting the driven member to rotate only. Therefore, through the cooperation between the third motor 211 and the power transmission component, the threaded shaft 212 can be driven to move up and down along the axis direction.

[0035] The working process of the hybrid component is as follows: Since the aperture of the material storage hole 2142 is known, the volume occupied by the raw materials in the material storage hole 2142 is calculated according to the amount of raw materials put into the mixing tank 205 as needed, and the height to which the piston 215 needs to move upward is calculated based on the volume, and then the threaded shaft 212 is driven to move upward so that the lower end of the threaded shaft 212 is at a corresponding height. When the piston 215 contacts the threaded shaft 212, the height at which the piston 215 is located is the height to be moved upward; The raw material is pulled by the peristaltic pump 206, passes through the feed pipe and the nozzle 2103, enters the storage hole 2142, and pushes the piston 215 upward, the spring 217 is compressed, and when the piston 215 contacts the threaded shaft 212, the raw material in the storage hole 2142 reaches a preset value, that is, a certain amount of raw material is injected into the storage hole 2142; Then, the second motor 209 drives the rotating body 214 to rotate, so that the material storage hole 2142 containing the raw material rotates to communicate with the notch 2102. At this time, the spring 217 releases its elastic force, and the solenoid valve opens at the same time. The inert gas is output through the connecting air pipe, the rotary joint, the air inlet pipe 213, the air hole 2141 and the connecting channel, and the gas during output is horizontally blown to the lower surface of the rotating body 214 at the notch 2102. Therefore, the following effects can be achieved: The spring 217 releases its elastic force, which can drive the piston 215 downward, thereby pushing the raw material in the storage hole 2142 downward. When the raw material passes through the notch 2102, it has an initial vertical velocity downward. As the elastic force of the spring 217 is released, the compression amount of the spring 217 decreases, the elastic force decreases, and the initial vertical velocity of the raw material gradually decreases. The inert gas blown out through the connecting channel can give the raw material passing through the notch 2102 an initial horizontal velocity in the horizontal direction, and the initial horizontal velocity is constant; 1. On the one hand, the horizontal displacement of the raw material can be different, so that the raw material can fall into the mixing tank 205 more evenly. On the other hand, when the raw material contacts the raw material previously placed in the mixing tank 205, the vertical speed is different. Therefore, the depth of the raw material into the raw material previously placed in the mixing tank 205 is different, so that the raw material can be more evenly penetrated into the raw material previously placed in the mixing tank 205. The combination of the two can achieve a preliminary mixing effect between the raw material placed in the mixing tank 205 this time and the raw material placed in the mixing tank 205 previously, so as to achieve the purpose of improving the mixing effect and mixing efficiency. 2. When the lower surface of the piston 215 is flush with the lower surface of the rotating body 214, the built-in step support nut stops the piston 215 from moving downward. At the same time, the inert gas blown out through the connecting channel can be blown to the lower surface of the piston 215, thereby blowing out the raw materials remaining on the lower surface of the piston 215, so that the raw materials in the material storage hole 2142 are all sent into the mixing tank 205, thereby improving the accuracy of quantitative feeding of raw materials into the mixing tank 205; It should be noted that, as known from the background technology, the raw materials include some powdered raw materials and cellulose raw materials. Therefore, it is easy for a small amount of raw materials to remain on the lower surface of the piston 215. If this part of the raw materials is not put into the mixing tank 205, the precision of quantitative input of the raw materials is poor. In addition, when the raw materials are put into the mixing tank 205, the stirring shaft 2053 is driven to rotate by the first motor 218 to stir the raw materials in the mixing tank 205. In addition, since at least two material storage holes 2142 are provided, one material storage hole 2142 is used for feeding materials and one material storage hole 2142 is used for discharging materials, which can improve the efficiency of quantitative input of raw materials.

[0036] In a preferred embodiment, as the raw materials are added, the air pressure in the mixing tank 205 increases continuously. Therefore, after each mixing of the raw materials, the inert gas in the mixing tank 205 should be discharged. Therefore, an exhaust pipe can be provided on the tank cover 2051, and the end of the exhaust pipe is connected to the air inlet end of the air pump 207, and the air outlet end of the air pump 207 is connected to the gas tank 208. After each mixing of the raw materials, the inert gas is drawn back into the gas tank 208 by the air pump 207.

[0037] 2. Output Components Reference Figure 2 The output component includes a supply tank 202, which is connected to the bottom pipe 2052 via a connecting pipe 201 and a valve 1 is provided on the connecting pipe 201. An output pipe 203 is provided at the bottom of the supply tank 202, an output nozzle 204 is provided at the lower end of the output pipe 203, and a valve 2 is provided on the output pipe 203.

[0038] After the raw materials are mixed, once the valve is opened, an inert gas is injected into the mixing tank 205, and the mixed materials can be pushed into the supply tank 202 for storage.

[0039] An auxiliary pipeline is provided on the connecting pipeline 201, and a valve three is provided on the auxiliary pipeline.

[0040] Valve 1 is closed, valves 2 and 3 are opened, and inert gas is injected into the connecting pipe 201 through the output pipe. The material in the supply tank 202 can be pushed into the output pipe 203 and output downward through the output nozzle 204 and fall onto the conveyor belt 101.

[0041] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
