Description

Technical Field

[0001] The invention relates to the field of toothpaste production, in particular to the field of toothpaste additive production, and in particular to a production and mixing device for a thin toothpaste additive. Background Art

[0002] Toothpaste is an essential substance for brushing teeth. In order to improve the effectiveness of toothpaste, toothpaste additives are generally added to toothpaste. For example, flake toothpaste additives are added to Colgate toothpaste.

[0003] Based on the search for toothpaste flake additives, a Chinese invention patent was found, and its authorization announcement number is CN109846749B, which discloses a flake toothpaste additive and a preparation method thereof, wherein starch, deionized water, and hydroxypropyl methylcellulose are stirred to obtain a mixture A, and then polyethylene glycol is added, and the mixture B is stirred, and then talcum powder, colorant, and deionized water are added, and the mixture C is uniformly dispersed by ultrasonic dispersion, and then sodium lauryl sulfate and methylparaben are added. After dissolving in deionized water, the mixture is slowly added to the mixture C, and after uniform stirring, the mixture is dried and sliced ​​to obtain a flake toothpaste additive. In the stirring process, since the raw materials constituting the mixture include water, starch, cellulose, etc., the mixed raw materials are in the form of a viscous fluid. When the raw materials are stirred and mixed by the existing stirring technology of rotating stirring blades, the part in contact with the rotating action can be effectively stirred, but the remaining part is not in contact with the blades and is a viscous fluid, and the stirring action of the rotating blades is difficult to be indirectly transmitted to the remaining part, resulting in a relatively poor stirring effect of the remaining part, and the stirring is not comprehensive and balanced.

[0004] A search based on the above-mentioned stirring problem revealed a Chinese invention patent application with the application publication number CN105582837A, which disclosed an up-and-down moving stirring device, in which a rotating motor drives the screw rod to rotate, thereby moving the fixed plate up and down, ensuring uniform density at various positions in the stirring barrel and improving the stirring quality. However, the essence of this stirring method is to achieve full and comprehensive stirring of the raw materials in the stirring barrel by moving the stirring paddle up and down while rotating the stirring paddle. Therefore, the rotation of the screw rod needs to be changed frequently, which requires constantly changing the direction of the current input to the motor to achieve this. The control is more troublesome and easily reduces the service life of the motor.

[0005] In addition, since the viscous fluid has viscosity, the stirred raw materials are likely to remain on the wall of the mixing tank when they are discharged.

[0006] Based on the above, the present invention proposes a production and mixing device for thin-sheet toothpaste additives. Summary of the invention

[0007] In order to solve the problems mentioned in the above background, the present invention provides a production and mixing device for thin-sheet toothpaste additives.

[0013] As a further improvement and optimization of the present invention, a notch is provided on the inner wall of the stirring tank, and a first rotating ring and a second rotating ring are installed at the notch, and both are coaxial with the stirring tank, and both can rotate around their own axis. The first rotating ring and the second rotating ring cooperate to seal the notch and keep the cross-section of the inner cavity of the stirring tank in a complete circular shape.

[0014] As a further improvement and optimization of the present invention, a circular frame is provided inside the stirring tank, and a second motor for driving the first rotating ring to rotate and a fourth motor for driving the second rotating ring to rotate are provided on the circular frame.

[0015] As a further improvement and optimization of the present invention, the stirring ring is connected to the first rotating ring.

[0016] As a further improvement and optimization of the present invention, both sides of the inner surface of the stirring ring along the axial direction are rounded, and the radius of the rounded corners is equal to the difference between the inner and outer radii of the stirring ring.

[0017] As a further improvement and optimization of the present invention, the stirring blade group includes an inner bracket connected to the second rotating ring, the stirring ring is provided with an avoidance opening for avoiding the inner bracket, the inner bracket is installed with blades, a connecting shaft is installed on the circular frame along the radial direction of the stirring tank, the input end of the connecting shaft is dynamically connected with the third motor arranged on the circular frame, the output end of the connecting shaft extends into the stirring tank and is dynamically connected with the blade shaft of the blade, and the second rotating ring and the inner bracket are both provided with avoidance holes for avoiding the connecting shaft.

During the rotation of the valve shaft, the valve hole can be connected with the inner cavity of the output nozzle or the inner cavity of the output nozzle can be blocked by the valve shaft.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] One of the core of this solution is to fully and comprehensively mix the raw materials to obtain each layer of material:

[0023] The first rotating ring is driven to rotate by the second motor, and the first rotating ring rotates with the stirring ring. At the same time, the second rotating ring is driven to rotate by the fourth motor, and the second rotating ring rotates with the stirring blade group. The third motor drives the blades of the stirring blade group to rotate around the blade axis, that is, the stirring blade group revolves and rotates. The stirring of the raw materials is achieved by the rotation of the stirring ring and the revolution and rotation of the stirring blade group. Specifically:

[0024] a. Since the inner cavity of the stirring tank is a closed annular loop, the revolution of the stirring blade group can drive the stirring blade group to rotate unidirectionally in the closed annular loop. Compared with the technology of moving the stirring blade up and down mentioned in the background technology, on the one hand, it can not only achieve the stirring of the raw materials at various positions, but also make the stirring more complete and comprehensive. Moreover, the fourth motor that drives the stirring blade group to revolve does not need to frequently change the input current direction. The fourth motor can keep normal startup and operation, which is more convenient to operate and will not cause additional loss to the fourth motor. On the other hand, in addition to driving the stirring blade group to move, the revolution action itself also has a stirring effect, which can further increase the stirring effect on the raw materials. The up and down movement mentioned in the background technology is essentially just moving the stirring blades, but does not have a stirring effect. The stirring is simply achieved by the rotation of the stirring blades.

[0025] b. The rotation of the stirring ring can scrape off the raw materials adhering to the wall of the stirring tank cavity, so that it can participate in the stirring action, that is, there is an effect of turning over the raw materials near the wall of the stirring tank cavity, thereby further improving the fullness of the stirring. Furthermore, the rounded corners of the stirring ring can further enhance its own turning over effect;

[0026] In addition, in the subsequent discharging process, the stirring ring keeps rotating to scrape the material and prevent the stirred material from remaining on the wall of the stirring tank cavity. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] 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.

[0043] Reference Figure 1-Figure 13 A production and mixing device for thin toothpaste additives includes a conveyor belt 100 and a plurality of mixing mechanisms 200 located above the conveyor belt 100 and arranged in an array along the conveying direction of the conveyor belt 100. The height of the output end of the mixing mechanism 200 increases successively along the conveying direction of the conveyor belt 100. In addition, a hot air drying structure is also arranged near the conveyor belt 100 to dry the toothpaste additive raw materials on the conveyor belt 100. The hot air drying structure can be achieved by heating the air with the existing electric heating technology and cooperating with the blowing of a fan, which will not be described in detail.

[0044] In this scheme, the thin toothpaste 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;

[0045] During production, firstly, different layers of materials are obtained by mixing raw materials through different mixing mechanisms 200, then, a layer of film is laid on the conveyor belt 100, and the conveyor belt 100 pulls the film to move. During the movement, the first layer of material is laid on the film through the first group of mixing mechanisms 200, and is dried by hot air at the same time, and then the second layer of material is laid on the dried first layer of material through the second group of mixing mechanisms 200, and this process is repeated to obtain a thin sheet of toothpaste additive, and finally, the thin sheet of toothpaste additive can be cut into a desired shape;

[0046] 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;

[0047] It should be noted that hot air drying, material conveying, bonding and other technologies are not the core of this solution, and existing technologies can be used without further elaboration. One of the cores of this solution is to fully stir and mix the raw materials to obtain each layer of material.

[0048] Hybrid 200: Reference Figure 3 The mixing mechanism 200 includes a feed hopper 201, a stirring member 202 is arranged at the bottom of the feed hopper 201, a storage tank 203 is arranged at the bottom of the stirring member 202, a peristaltic pump 204 is arranged at the bottom of the storage tank 203, a connecting pipe 205 is arranged at the output end of the peristaltic pump 204, and an output component 206 is arranged at the end of the connecting pipe 205; when in use, the raw material is poured into the feed hopper 201, and the raw material is guided into the stirring member 202 through the feed hopper 201. The material obtained after stirring is stored in the storage tank 203, and is pulled to the output component 206 by the peristaltic pump 204, and is output outwardly through the output component 206, and finally laid on the film on the conveyor belt 100 or on the upper layer of material.

[0049] Stirring member 202: see Figure 6-Figure 13 The stirring member 202 includes a support body 207 and a stirring tank 214 arranged horizontally with an axis line. The stirring tank 214 is in the shape of a hollow ring and the cross-section of the inner cavity of the stirring tank 214 is circular. Furthermore, the stirring tank 214 is composed of two semicircular rings.

[0050] The outer circumferential surface of the stirring tank 214 is provided with an inlet and outlet hole 2141 along the radial direction.

[0051] The outer sleeve of the stirring tank 214 is provided with a fixed ring 208, and the fixed ring 208 is connected to the bracket body 207. Therefore, the fixed ring 208 cannot rotate, but the stirring tank 214 can rotate. Furthermore, a convex ring extends coaxially from the end face of the stirring tank 214, and the convex ring is dynamically connected to the first motor 209 arranged on the bracket body 207, so that the stirring tank 214 can be driven to rotate by the first motor 209.

[0052] An upper nozzle 2081 is provided at the highest point of the outer circumferential surface of the fixed collar 208, and a lower nozzle 2082 is provided at the lowest point. During the rotation of the stirring tank 214, the inlet and outlet holes 2141 can be connected with the upper nozzle 2081 or the lower nozzle 2082 to realize feeding or discharging. In addition, when the inlet and outlet holes 2141 are blocked by the inner wall of the fixed collar 208, stirring action is taking place in the stirring tank 214. This feeding and discharging method can reduce the existence of stirring dead corners as much as possible during stirring to improve the stirring effect.

[0053] A notch is provided on the inner wall of the stirring tank 214, and a first rotating ring 216 and a second rotating ring 217 are installed at the notch. Both are coaxial with the stirring tank 214 and can rotate, and the two cooperate to block the notch and keep the cross-section of the inner cavity of the stirring tank 214 in a complete circular shape. Furthermore, a circular frame 210 is provided inside the stirring tank 214, and a second motor 211 for driving the first rotating ring 216 to rotate and a fourth motor 213 for driving the second rotating ring 217 to rotate are provided on the circular frame 210.

[0054] A stirring ring 218 and a stirring blade assembly 219 are installed in the stirring tank 214 .

[0055] The stirring ring 218 is in a circular ring shape and the outer circumferential surface of the stirring ring 218 is in contact with the cavity wall of the stirring tank 214 . The stirring ring 218 is connected to the first rotating ring 216 , so the first rotating ring 216 rotates with the stirring ring 218 .

[0056] The stirring blade group 219 includes an inner bracket 2191 connected to the second rotating ring 217, a avoidance opening for avoiding the inner bracket 2191 is provided on the stirring ring 218, and a blade 2192 is installed on the inner bracket 2191. A connecting shaft 215 is installed on the circular frame 210 along the radial direction of the stirring tank 214. The input end of the connecting shaft 215 is connected to the third motor 212 provided on the circular frame 210 to form a power connection, and the output end of the connecting shaft 215 extends into the stirring tank 214 and forms a power connection with the blade shaft of the blade 2192. The second rotating ring 217 and the inner bracket 2191 are both provided with avoidance holes for avoiding the connecting shaft 215; the second rotating ring 217 When rotating, it can rotate with the stirring blade group 219, which is called revolution. At the same time, the third motor 212 and the connecting shaft 215 can drive the blades 2192 of the stirring blade group 219 to rotate around their own axis, which is called rotation. In addition, it should be noted that the connecting shaft 215 and the third motor 212 are powered by bevel gear technology. Therefore, when the stirring blade group 219 revolves, if the active bevel gear does not move, the driven bevel gear will also rotate around its own axis, thereby causing the stirring blade group 219 to rotate at the same time, but the rotation speed is relatively slow. Therefore, the drive of the third motor 212 is required to speed up the rotation speed.

[0057] Furthermore, the stirring rings 218 and the stirring blade groups 219 are arranged in multiple groups in an array along the circumferential direction of the stirring tank 214, and the attached figure of this solution shows two groups.

[0058] Furthermore, the two sides of the inner ring surface of the stirring ring 218 along the axis direction are rounded and the radius of the rounded corners is equal to the difference between the inner and outer radii of the stirring ring 218. Fig.12 As shown, both ends of the stirring ring 218 are respectively formed with an arc surface.

[0059] The working process of the stirring member 202 is specifically as follows:

[0060] The stirring tank 214 is driven to rotate by the first motor 209, so that the inlet and outlet holes 2141 are connected with the upper nozzle 2081, and the raw materials are guided to fall into the stirring tank 214 through the feeding hopper 201, which is feeding. After the feeding is completed, the stirring tank 214 is driven to rotate by the first motor 209, so that the inlet and outlet holes 2141 are blocked by the fixing ring 208;

[0061] The first rotating ring 216 is driven to rotate by the second motor 211, and the first rotating ring 216 rotates with the stirring ring 218. At the same time, the second rotating ring 217 is driven to rotate by the fourth motor 213, and the second rotating ring 217 rotates with the stirring blade group 219. The blades 2192 of the stirring blade group 219 are driven to rotate around the blade axis by the third motor 212, that is, the stirring blade group 219 revolves and rotates. The stirring of the raw materials is achieved by the rotation of the stirring ring 218 and the revolution and rotation of the stirring blade group 219. Specifically:

[0062] a. Since the inner cavity of the stirring tank 214 is a closed annular loop, the revolution of the stirring blade group 219 can drive the stirring blade group 219 to rotate unidirectionally in the closed annular loop. Compared with the technology of moving the stirring blade up and down mentioned in the background technology, on the one hand, it can not only achieve the stirring of the raw materials at various positions, but also make the stirring more complete and comprehensive. Moreover, the fourth motor 213 that drives the stirring blade group 219 to revolve does not need to frequently change the input current direction. The fourth motor 213 can maintain normal starting movement, which is more convenient to operate and will not cause additional loss to the fourth motor 213. On the other hand, in addition to driving the stirring blade group 219 to move, the revolution itself also has a stirring effect, which can further increase the stirring effect on the raw materials. The up and down movement mentioned in the background technology is essentially just moving the stirring blades, but does not have a stirring effect. The stirring is simply achieved by the rotation of the stirring blades.

[0063] b. The rotation of the stirring ring 218 can scrape off the raw materials adhering to the wall of the stirring tank 214, so that the raw materials can participate in the stirring action, that is, there is an effect of turning over the raw materials near the wall of the stirring tank 214, thereby further improving the fullness of the stirring. Furthermore, the rounded corners of the stirring ring 218 can further enhance its own turning over effect;

[0064] In addition, during the subsequent discharging process after stirring, the stirring ring 218 keeps rotating to scrape the material and prevent the stirred material from partially remaining on the cavity wall of the stirring tank 214;

[0065] After stirring, the first motor 209 is used to drive the stirring tank 214 to rotate, so that the inlet and outlet holes 2141 are connected with the lower nozzle 2082, and the raw materials are guided to fall into the storage tank 203 through the lower nozzle 2082. This is the discharge. It should be noted that the upper surface of the storage tank 203 is provided with an air outlet pipe, which is used to provide a discharge path for the internal air when receiving the stirred material.

[0066] Output component 206: Reference Figure 4 and Figure 5The output component 206 includes a storage shell 2061 , and a side nozzle 2062 is provided on the outer surface of the storage shell 2061 . The side nozzle 2062 is connected to the connecting pipe 205 , and the side nozzle 2062 is close to the lower opening end of the storage shell 2061 .

[0067] A piston 2063 is sleeved in the storage shell 2061 and the piston 2063 is driven by a linear module 2064 disposed on the storage shell 2061 to move in the storage shell 2061 .

[0068] An output nozzle 2065 is provided at the lower open end of the storage shell 2061, and the length direction of the output nozzle 2065 is parallel to the width direction of the conveyor belt 100. A mounting hole is provided in the output nozzle 2065, and a valve shaft 2066 is sleeved in the mounting hole. The valve shaft 2066 is poweredly connected with a valve motor 2067 provided on the outer surface of the storage shell 2061, and the valve motor 2067 can drive the valve shaft 2066 to rotate. A valve hole is radially penetrated on the outer cylindrical surface of the valve shaft 2066, and by driving the valve shaft 2066 to rotate, the valve hole can be connected to the inner cavity of the output nozzle 2065 or the inner cavity of the output nozzle 2065 can be blocked by the valve shaft 2066. The former means that the output nozzle 2065 is open, and the latter means that the output nozzle 2065 is blocked.

[0069] Initially, the piston 2063 is in contact with the upper surface of the output nozzle 2065 .

[0070] The working process of the output component 206 is specifically as follows:

[0071] The stirred material in the storage tank 203 is pulled by the peristaltic pump 204 and flows into the storage shell 2061. At the same time, the piston 2063 is pulled upward by the linear module 2064. The two cooperate to realize the injection of the material into the storage shell 2061.

[0072] After the injection is completed, the solenoid valve arranged on the connecting pipe 205 is closed, the output nozzle 2065 is opened, the piston 2063 is pulled downward by the linear module 2064, and the material is output downward through the output nozzle 2065. Since the film or the upper layer of material is pulled and moved by the conveyor belt 100, the material output downward will be spread flat on the film or the upper layer of material.

[0073] 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.
