Description

Technical Field

[0001] The invention relates to the technical field of material mixing, in particular to a highly dispersible modified gold paste mixing device for thermal printing sheets and a process thereof. Background Art

[0002] Thermal printing sheet is a kind of precision electric heating device. Each thermal sheet has a heating line, and there are many tiny heating points arranged on this heating line, with a density of 8 heating points within 1mm. When the heating point heats up, the corresponding position of the thermal paper pressed on the thermal sheet will turn black. When the paper roll is dragged by the motor, the heating point will also change according to the change of the printing data, and finally form text or pattern on the thermal paper. Gold paste is the circuit component material of thermal printing sheet. After printing and firing, it is exposed and etched to form the circuit layout. The quality of thermal sheet determines the printing effect. Therefore, the quality of gold paste and firing effect also determine the printing effect of thermal sheet.

[0003] 1. Since the modified gold paste is made by mixing a variety of modified powders and stock solutions, many powders will have agglomeration during storage. Some agglomerates can be broken up by stirring, but some agglomerates are difficult to break up due to changes in the properties of the material after deterioration. Generally speaking, impurities in liquids with good fluidity can be removed by more conventional methods such as filtration and adsorption. However, for very thick liquids such as modified gold paste, the conventional means recorded in the prior art cannot effectively remove hard impurities in thick liquids.

[0004] 2. Add the various raw materials required for the modified gold paste into the stirring kettle in sequence for mixing. As the stirring proceeds, the raw materials are added in sequence, and the gold paste stock solution in the mixing equipment becomes thicker and thicker. Initially, the stock solution still has a certain fluidity. As various modified powdered raw materials are added in sequence, the fluidity of the stock solution becomes worse and worse. The traditional stirring method is difficult to achieve a relatively uniform and ideal mixing effect on the viscous stock solution;

[0005] Secondly, a general mixing device will have a stirring structure at the center of the mixing barrel. When the stirring structure rotates, it can divide and stir the material in the barrel. However, when stirring a fluid, the closer the material is to the stirring center, the stronger the stirring effect it is subjected to. The stirring force formed at the center of the fluid will continuously produce a suction force on the material to move toward the center (similar to the vortex in water that can suck in surrounding water and matter), which will produce an adsorption force toward the center. There are differences in density and mass between the original liquid and the uncluttered bulk powder. When subjected to the same adsorption force, there will be a difference in movement speed between the liquid and the bulk powder. Therefore, the adsorption effect toward the center is like solid-liquid separation for the fluid. This results in a certain degree of separation between the uncluttered powder and the original liquid after the final stirring, making it impossible for the bulk powder to be effectively dispersed and it will also gather in the center of the stirring area.

[0006] In view of the above problems, it is urgent to carry out innovative design based on the original high-dispersion modified gold paste mixing equipment for thermal printing sheets. Summary of the invention

[0007] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. Specifically, the purpose of the present invention is to provide a highly dispersed modified gold paste mixing device and a process for thermal printing sheets, so as to solve the problem that the above-mentioned background technology proposes to add the various raw materials required for the modified gold paste into a stirring kettle in sequence for mixing treatment. As the stirring proceeds and the raw materials are added in sequence, the gold paste stock solution in the mixing equipment will become more and more viscous. Initially, the stock solution still has a certain fluidity. As various types of modified powdered raw materials are added in sequence, the fluidity of the stock solution will become worse and worse. The traditional stirring method is difficult to achieve a relatively uniform and ideal mixing and stirring effect on the viscous stock solution.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a highly dispersible modified gold paste mixing device for thermal printing sheets, comprising a stirring outer cylinder, a separation inner cylinder is fixedly installed at the center of the stirring outer cylinder, and a side plate is fixedly installed on the outer wall of the stirring outer cylinder, a driving motor is fixedly installed on the upper end of the side plate, and the output shaft of the driving motor passes through the side plate through a bearing and is fixedly connected to a triangular plate, a fixed gear is fixed to the lower end of the side plate, and a planetary gear is meshed at an equal angle on the outer wall of the fixed gear, a driven shaft is fixed to the lower end of the planetary gear, and the driven shaft passes through the end of the triangular plate through a bearing and is fixedly connected to a turntable, and a stirring rod which can be driven to rotate and contract and can crush and push up block materials by the extrusion force generated by the cone approaching is arranged at an equal angle at the lower end of the turntable.

[0009] Preferably, the space between the stirring outer cylinder and the separation inner cylinder is an annular mixing area, and a discharge pipe is installed at the lower end of the stirring outer cylinder corresponding to the mixing area.

[0010] Preferably, the upper and lower ends of the separation inner cylinder are of through-type design, and the outer wall of the separation inner cylinder is provided with convex arc structures at equal angles, and the width of the annular mixing area between the stirring outer cylinder and the separation inner cylinder is of gradual design.

[0011] Preferably, the center of the fixed gear shares a central axis with the center of the output shaft of the driving motor and the center of the triangular plate.

[0012] Preferably, the stirring rod is arranged in a frustum shape, with the large diameter end of the frustum at the bottom, and a retractable reset component is installed between the stirring rod and the turntable.

[0013] Preferably, the contraction and reset assembly includes a fixed disk and a guide rod, and the fixed disk is fixed at the center of the lower surface of the turntable, the guide rod is fixed at an equal angle to the outer wall of the fixed disk, and the upper end of the stirring rod is sleeved on the outer wall of the guide rod, and the small diameter upper end of the stirring rod is attached to the lower surface of the turntable.

[0014] Preferably, the guide rod is L-shaped, and a return spring is wound around the outer wall of the guide rod, one end of the return spring is welded to the side wall of the stirring rod, and the other end of the return spring is fixed to the side wall of the fixed disk.

[0015] A highly dispersible modified gold paste mixing process for thermal printing sheets comprises the following steps:

[0016] S1: Pour the gold slurry and various modified powders into the annular mixing area between the mixing outer cylinder and the separation inner cylinder in sequence. The driving motor stably drives the triangular plate and the driven shaft to rotate through the output shaft, and the planetary gear also moves clockwise along the outer wall of the fixed gear.

[0017] S2: The four stirring rods in each stirring unit will revolve in the annular mixing area between the stirring outer cylinder and the separation inner cylinder. At the same time, the four stirring rods will rotate along with the turntable to achieve a combined rotation and revolution operation state. The multi-point distribution variable stirring method is adopted to break the whole into parts, which has better pertinence for the mixing of materials and liquids, effectively reducing the liquid tension on the blades during wet stirring and reducing the output load;

[0018] S3: The separation inner cylinder is designed in a special form, and its outer wall is provided with convex arc structures at equal angles. When the four stirring rods revolve in the annular mixing area between the stirring outer cylinder and the separation inner cylinder, since the width of the annular mixing area changes all the time and is the smallest at the inflection point, the four stirring rods are accompanied by another action while rotating and revolving, that is, they move closer to the center and shrink;

[0019] S4: Since the stirring rod is in a cone shape with the large diameter end facing downward, the four groups of stirring rods will be quickly tightened under the tightening of the inner and outer cylinder walls, and the four groups of stirring rods that are quickly retracted will quickly squeeze the agglomerated materials and crush them, thereby achieving the effect of efficiently breaking up the agglomerated materials;

[0020] S5: If the agglomerated powders between the four groups of stirring rods cannot be crushed in this way, the inclined outer walls of the four groups of conical stirring rods with their large ends facing downward will gradually exert an upward squeezing and pushing force on the agglomerated powders that cannot be broken up, so that the agglomerated powders that cannot be crushed are lifted up by the four groups of stirring rods that are gradually approaching each other. Since the four groups of stirring rods rotate and revolve simultaneously, the stirring outer cylinder is higher than the separation inner cylinder. Therefore, the agglomerated powders or other foreign matter that are gradually lifted up will gradually be thrown out into the separation inner cylinder under the action of the rotating centrifugal force, thereby being able to adaptively discharge impurities and blocky powders that are difficult to break up through the separation inner cylinder.

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

[0022] Effect 1: When mixing modified gold slurry according to fluid properties, the stirring rod will revolve along the outer ring of the fixed gear on the one hand, and will rotate along the corresponding turntable on the other hand, achieving a combined rotation and revolution operation state. A multi-point distribution variable stirring method is adopted to break the whole into parts, which has good pertinence for the mixing of materials and liquids, effectively reducing the liquid tension on the blades during wet stirring, and reducing the output load. At the same time, when the four stirring rods rotate and revolve at the same time, for very viscous modified gold slurry, they have a rotating stirring effect in multiple directions, unlike the traditional stirring mechanism, which only rotates in one direction to cause solid-liquid separation, resulting in a certain degree of separation between the undispersed powder and the original liquid after the final stirring, so that the block powder cannot be effectively dispersed and will gather in the central area of ​​the stirring;

[0023] Secondly, the present invention adopts a combination of rotation and revolution and combines a new motion state, that is, during the rotation and revolution of the four stirring rods, under the restriction of the inner wall of the annular mixing area with gradually changing width between the stirring outer cylinder and the separation inner cylinder, the four stirring rods will periodically and adaptively move closer to achieve a "kneading dough" effect, first tearing the dough apart and then squeezing it in the middle, then tearing it apart again and squeezing it in the middle in this cycle, which has a higher stirring and dispersing effect for the modified gold paste with higher viscosity, and can prevent the "solid-liquid separation" problem caused by single-direction rotation;

[0024] Effect 2: When there are agglomerated materials between the four groups of stirring rods, due to the poor fluidity of the agglomerated materials, the four groups of stirring rods will be quickly tightened under the tightening of the inner and outer cylinder walls, and the four groups of stirring rods that are quickly retracted will quickly squeeze the agglomerated materials and crush them, thereby achieving the effect of efficiently breaking up the agglomerated materials;

[0025] Effect three: If the agglomerated powder between the four groups of stirring rods cannot be crushed by the method of effect two, the smooth and frustum-shaped stirring rods begin to play a role. Under the condition that the mixing area between the inner and outer cylinders gradually narrows, the four groups of frustum-shaped stirring rods with their large ends facing downwards will gradually converge inward during the revolution and position the agglomerated materials between the four stirring rods. As the convergence proceeds, the four inclined outer walls will gradually exert an upward squeezing and pushing effect on the agglomerated powder that cannot be broken up, so that the agglomerated powder is gradually pushed up by the four groups of gradually approaching stirring rods. Since the four groups of stirring rods rotate and revolve at the same time, and the stirring outer cylinder is higher than the separation inner cylinder, the agglomerated powder or other foreign matter that is gradually pushed up will gradually be thrown out from the gap between the upper ends of the stirring rods into the separation inner cylinder under the action of rotating centrifugation, so that the agglomerated powder or other hard impurities that are difficult to break up can be adaptively discharged through the separation inner cylinder. The structure is simple and ingenious, the functionality is strong, and it is suitable for mixing and stirring a variety of materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-7 The present invention provides a technical solution: a highly dispersible modified gold paste mixing device for thermal printing sheets, comprising a stirring outer cylinder 1, a separation inner cylinder 2 is fixedly installed at the center of the stirring outer cylinder 1, and a side plate 11 is fixedly installed on the outer wall of the stirring outer cylinder 1, a driving motor 12 is fixedly installed on the upper end of the side plate 11, and the output shaft of the driving motor 12 passes through the side plate 11 through a bearing and is fixedly connected to a triangular plate 14, a fixed gear 13 is fixed to the lower end of the side plate 11, and a planetary gear 3 is meshed with the outer wall of the fixed gear 13 at an equal angle, a driven shaft 31 is fixed to the lower end of the planetary gear 3, and the driven shaft 31 passes through the end of the triangular plate 14 through a bearing and is fixedly connected to a turntable 32, and a stirring rod 4 is arranged at an equal angle on the lower end of the turntable 32, which can be driven to rotate and shrink and can crush and push up block materials by using the extrusion force generated by the cones approaching.

[0036] The space between the stirring outer cylinder 1 and the separation inner cylinder 2 is an annular mixing area, and a discharge pipe is installed at the lower end of the stirring outer cylinder 1 corresponding to the mixing area.

[0037] The upper and lower ends of the separation inner cylinder 2 are of through-type design, and the outer wall of the separation inner cylinder 2 is provided with convex arc structures at equal angles, and the width of the annular mixing area between the stirring outer cylinder 1 and the separation inner cylinder 2 is of gradual design.

[0038] The center of the fixed gear 13 , the center of the output shaft of the driving motor 12 , and the center of the triangular plate 14 share a central axis.

[0039] The stirring rod 4 is arranged in a frustum shape, with the large diameter end of the frustum at the bottom, and a retracting and resetting component is installed between the stirring rod 4 and the rotating disk 32 .

[0040] The contraction and reset assembly includes a fixed disk 41 and a guide rod 42, and the fixed disk 41 is fixed at the center of the lower surface of the turntable 32, the guide rod 42 is fixed at an equal angle to the outer wall of the fixed disk 41, and the upper end of the stirring rod 4 is sleeved on the outer wall of the guide rod 42, and the small diameter upper end of the stirring rod 4 is attached to the lower surface of the turntable 32.

[0041] The guide rod 42 is L-shaped, and a return spring 43 is wound around the outer wall of the guide rod 42 . One end of the return spring 43 is welded to the side wall of the stirring rod 4 , and the other end of the return spring 43 is fixed to the side wall of the fixed plate 41 .

[0042] A highly dispersible modified gold paste mixing process for thermal printing sheets comprises the following steps:

[0043] S1: Pour the gold slurry and various modified powders into the annular mixing area between the stirring outer cylinder 1 and the separation inner cylinder 2 in sequence, and the driving motor 12 stably drives the triangular plate 14 and the driven shaft 31 to rotate through the output shaft, and the planetary gear 3 also moves clockwise along the outer wall of the fixed gear 13;

[0044] S2: The four stirring rods 4 in each stirring unit are overall realized to revolve in the annular mixing area between the stirring outer cylinder 1 and the separation inner cylinder 2. At the same time, the four stirring rods 4 will rotate along with the turntable 32, achieving an operation state combining rotation and revolution. The stirring method of multi-point distribution variation is adopted, which is divided into parts and has good pertinence for the mixing of materials and liquids, effectively reducing the liquid tension on the blades during wet stirring and reducing the output load;

[0045] S3: The separation inner cylinder 2 is designed in a special form, and its outer wall is provided with convex arc structures at equal angles. When the four stirring rods 4 revolve in the annular mixing area between the stirring outer cylinder 1 and the separation inner cylinder 2, since the width of the annular mixing area changes all the time and is the smallest at the inflection point, the four stirring rods 4 are accompanied by another action while rotating and revolving, that is, they are shrunk toward the center;

[0046] S4: Since the stirring rod 4 is in a cone shape with the large diameter end facing downward, the four groups of stirring rods 4 will be quickly tightened under the tightening of the inner and outer cylinder walls, and the four groups of stirring rods 4 that are quickly retracted will quickly squeeze the agglomerated materials and crush them, thereby achieving the effect of efficiently breaking up the agglomerated materials;

[0047] S5: If the agglomerated powders between the four groups of stirring rods 4 cannot be crushed in this way, the inclined outer walls of the four groups of conical stirring rods 4 with their large ends facing downward will gradually exert an upward squeezing and pushing effect on the agglomerated powders that cannot be broken up, so that the agglomerated powders that cannot be crushed are pushed up by the four groups of stirring rods 4 that are gradually approaching each other. Since the four groups of stirring rods 4 rotate and revolve simultaneously, the stirring outer cylinder 1 is higher than the separation inner cylinder 2. Therefore, the agglomerated powders or other foreign matters that are gradually pushed up will gradually be thrown out into the separation inner cylinder 2 under the action of rotating centrifugation, thereby being able to adaptively discharge impurities and blocky powders that are difficult to break up through the separation inner cylinder 2.

[0048] When using the highly dispersible modified gold paste mixing equipment for thermal printing sheets, first Figure 1 and Figure 5As shown, the gold slurry stock solution is placed in the annular mixing area between the stirring outer cylinder 1 and the separation inner cylinder 2, and then a variety of modified powders are poured in in turn according to the required proportions, and then the drive motor 12 is started. The drive motor 12 stably drives the triangular plate 14 to rotate clockwise through the output shaft, and the triangular plate 14 will synchronously drive the three groups of driven shafts 31 to rotate clockwise. When the driven shaft 31 follows the triangular plate 14 to rotate clockwise, the planetary gear 3 at the upper end will also move clockwise along the outer wall of the fixed gear 13. Since the fixed gear 13 is stationary, the planetary gear 3 will adaptively rotate while following the triangular plate 14 to revolve clockwise, so that the planetary gear 3 synchronously drives the driven shaft 31, the turntable 32 and the four groups of stirring rods 4 at the lower end to rotate continuously with the driven shaft 31 as the axis.

[0049] At this time, the motion state of the four groups of stirring rods 4 at the lower end is to revolve around the output shaft in the mixing area between the stirring outer cylinder 1 and the separation inner cylinder 2, and at the same time rotate around the driven shaft 31. A multi-point distribution variable stirring method is adopted to break the whole into parts, which has good pertinence for the mixing of materials and liquids, effectively reduces the liquid tension on the blades during wet stirring, and reduces the output load. At the same time, the stirring position and angle of each stirring rod 4 are constantly changing, reducing the output frequency at the same position, and effectively avoiding the problem of dry-wet separation caused by central suction on the fluid during stirring.

[0050] Next, compare Figure 1 Figure 5 and Figure 6 , the following Figure 6 Taking the lower left turntable 32 and its attached stirring rods 4 as an example, when the turntable 32 carries the four groups of stirring rods 4 below and rotates clockwise along the mixing area between the stirring outer cylinder 1 and the separation inner cylinder 2, the width of the mixing area between the stirring outer cylinder 1 and the separation inner cylinder 2 gradually narrows during this cycle. Therefore, the four groups of stirring rods 4 rotating and revolving clockwise will gradually be resisted by the inner walls on both sides of the mixing area, so that the four groups of stirring rods 4 are as follows. Figure 6As shown, the four groups of stirring rods 4 move inward along their respective guide rods 42 and compress the return spring 43. When the four groups of stirring rods 4 gradually move closer, the gold slurry between the four groups of stirring rods 4 will gradually overflow from the gap between two adjacent stirring rods 4. However, when there is agglomerated material between the four groups of stirring rods 4, due to the poor fluidity of the agglomerated material, the four groups of stirring rods 4 will also be quickly tightened under the tightening of the inner and outer cylinder walls, and the four groups of stirring rods 4 that are quickly retracted will quickly squeeze the agglomerated material and crush it, thereby achieving the effect of efficiently breaking up the agglomerated material. If the agglomerated powder between the four groups of stirring rods 4 cannot be crushed in this way, the inclined outer walls of the four groups of frustum-shaped stirring rods 4 with their large heads facing downward will gradually produce an upward squeezing and pushing effect on the agglomerated powder that cannot be broken up, so that the agglomerated powder is gradually pushed upward by the four groups of stirring rods 4 that are gradually moving closer. Since the four groups of stirring rods 4 rotate and revolve at the same time, and as Figure 1 As shown, the mixing outer cylinder 1 is higher than the separation inner cylinder 2, so that the gradually lifted agglomerated powder and other foreign matters will be gradually thrown out into the separation inner cylinder 2 under the action of rotating centrifugation, so that the impurities and the block powder that is difficult to break up can be adaptively discharged through the separation inner cylinder 2. The structure is simple and ingenious, the functionality is strong, and it is suitable for mixing and stirring a variety of materials.

[0051] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
