Description

Technical Field

[0001] This invention relates to the field of thermal printing technology, specifically to a device and process for preparing modified gold paste for thermal printing sheets. Background Technology

[0002] A thermal printing sheet is a precision electrothermal device. Each thermal sheet has a heating wire with many tiny heating points arranged along it, at a density of eight heating points per millimeter. When these heating points heat up, the corresponding area of ​​the thermal paper pressed against the thermal sheet turns black. As the paper roll is driven by a motor, the heating points also change according to the printing data, ultimately forming text or patterns on the thermal paper.

[0003] Gold paste is the circuit material of thermal printing sheets. After printing and firing, it is exposed and etched to form the circuit layout. The quality of the thermal sheet determines the printing effect. Therefore, the quality of the gold paste and the firing effect also determine the printing effect of the thermal sheet.

[0004] In the preparation of modified gold paste, the raw materials required for the modified gold paste are generally added into a mixing tank in sequence for mixing. The stirring force output by the mixing tank is generally constant. However, the raw materials required for the preparation of gold paste contain viscous substances such as resin. These substances may adhere to the tank wall, resulting in uneven mixing between the raw materials and poor quality of the gold paste. Summary of the Invention

[0005] The purpose of this invention is to provide a preparation device and process for modified gold paste for thermal printing sheets, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A device for preparing modified gold paste for thermal printing sheets, comprising: A support frame, on which a processing tank is fixedly mounted, and a fixing plate is fixedly mounted on the top of the processing tank, and a baffle is fixedly mounted on the fixing plate; A drive assembly is mounted on the fixed plate and connected to the processing tank.

[0008] As a further embodiment of the present invention: the trigger transmission mechanism includes a rotating rod rotatably installed inside the processing tank, a movable rod movably installed inside the rotating rod, a movable limiting tooth fixed at one end of the movable rod away from the rotating rod, an elastic component connected to the rotating rod and the movable rod provided inside the processing tank, the fixed limiting tooth engaging with the movable limiting tooth, and the rotating rod being connected to the enhanced stirring mechanism and fixedly connected to the second stirring blade.

[0009] As a further embodiment of the present invention: the elastic component includes a fixed ring fixedly installed on the rotating rod, a spring sleeved on the rotating rod and the movable rod, a stationary contact fixed on the fixed limiting tooth, a movable contact cooperating with the stationary contact fixed on the movable limiting tooth, and the two ends of the spring abutting against the movable limiting tooth and the fixed ring respectively.

[0010] As a further embodiment of the present invention: the enhanced stirring mechanism includes a support sleeve fixedly installed on the rotating rod and symmetrically arranged, a support rod movably installed inside the support sleeve, a movable ring movably installed on the support rod, a sliding assembly connected to the movable ring and the rotating rod inside the processing tank, the sliding assembly being connected to the guide assembly, the support sleeve being connected to the reciprocating oscillating assembly, and the support rod being fixedly connected to the first stirring blade.

[0011] As a further embodiment of the present invention: the sliding assembly includes a receiving plate fixedly installed on the rotating rod, the receiving plate having symmetrically arranged sliding grooves, a sliding block being slidably installed in the sliding grooves, and symmetrically arranged limiting rods being fixed on the movable ring, one of the limiting rods being fixedly connected to the sliding block, and the other limiting rod being connected to the guide assembly.

[0012] As a further embodiment of the present invention: the guiding assembly includes a movable sleeve movably mounted on the rotating rod, a turntable fixed to one end of the movable sleeve facing the processing tank, a first arc-shaped groove formed on the side of the turntable away from the movable sleeve, an inclined groove communicating with the first arc-shaped groove on one side of the turntable, a second arc-shaped groove communicating with the inclined groove on one side of the turntable, the first arc-shaped groove, the inclined groove, and the second arc-shaped groove being slidably connected to the limiting rod, and the movable sleeve being connected to the coaxial reversing assembly.

[0013] As a further embodiment of the present invention: the reciprocating oscillating assembly includes a guide groove formed in the inner wall of the support sleeve, and the inner wall of the support sleeve is also provided with a straight groove communicating with the guide groove, and a protrusion fixed on the support rod is slidably connected with the guide groove and the straight groove.

[0014] As a further embodiment of the present invention: the coaxial reversing assembly includes an incomplete gear ring fixedly mounted on the transmission rod, a first pinion gear meshing with the incomplete gear ring is rotatably mounted on the baffle, and a second pinion gear meshing with the first pinion gear is also rotatably mounted on the baffle. The coaxial reversing assembly also includes a support slide rail fixedly installed on the top of the processing tank. A sliding ring is slidably installed inside the support slide rail, and a fully geared ring that meshes with the second pinion is fixed on the sliding ring. The fully geared ring is fixedly connected to the movable sleeve.

[0015] A process for preparing a modified gold paste for thermal printing sheets includes the following steps: Step 1: Weigh the raw materials according to the proportions, and add the weighed raw materials into the processing tank in sequence; Step 2: Under the action of the drive component, the second stirring blade is controlled to rotate by the trigger transmission mechanism. The trigger transmission mechanism will also drive the enhanced stirring mechanism to rotate, so that the first stirring blade can be rotated to mix the raw materials in the processing tank. Step 3: In order to prevent the sticky material contained in the raw materials from adhering to the inner wall of the processing tank and causing uneven mixing, under the action of the guiding component, the No. 1 stirring blade is controlled to move towards the inner wall of the processing tank by the enhanced stirring mechanism, and under the action of the reciprocating oscillation component, the No. 1 stirring blade is controlled to oscillate back and forth at a certain angle until the No. 1 stirring blade comes into contact with the inner wall of the processing tank, thereby scraping off the adhering raw materials. Step 4: The drive component can also drive the guide component to move through the coaxial reversing component, so that the first stirring blade can completely scrape off the adhering raw materials. As the raw materials are mixed more thoroughly, the resistance of the first and second stirring blades is reduced, which triggers the transmission mechanism to work and sends a signal to remind the staff that the modified gold paste preparation is complete, thereby avoiding the problem of poor quality of modified gold paste due to over-stirring.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This application can scrape off the sticky substances on the inner wall of the processing tank. When it is necessary to prepare gold paste, the raw materials can be added into the processing tank according to the ratio. Under the action of the drive component, the trigger transmission mechanism is driven to move, so that the second stirring blade rotates. At the same time, the trigger transmission mechanism will also drive the enhanced stirring mechanism to move, so that the first stirring blade rotates, thereby comprehensively stirring the materials in the processing tank. Under the action of the guide component, the enhanced stirring mechanism can also drive the first stirring blade to move towards or away from each other, so that the first stirring blade intermittently touches the inner wall of the processing tank. The material adheres to the inner wall of the processing tank by contacting the material. While the first stirring blade moves, the reciprocating oscillating component causes the first stirring blade to oscillate at a certain angle to enhance the mixing effect of the raw materials. The drive component also drives the coaxial reversing component to move, causing the guide component to move intermittently and irregularly, thus ensuring that the first stirring blade can completely scrape the inner wall of the processing tank. After the material in the processing tank is mixed, the resistance experienced by the first and second stirring blades will decrease. Under the action of the trigger transmission mechanism, this information can be released to prevent the raw materials from being over-mixed, resulting in poor quality. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0030] Please see Figures 1-10 In this embodiment of the invention, a device for preparing modified gold paste for thermal printing sheets includes: a support 1, a processing tank 2, a fixing plate 3, a baffle 4, a drive assembly, a trigger transmission mechanism, a second stirring blade 37, an enhanced stirring mechanism, a first stirring blade 31, a guide assembly, a reciprocating oscillating assembly, and a coaxial reversing assembly. Because the raw materials for preparing the modified gold paste contain highly viscous substances such as resin, these substances may adhere to the inner wall of the processing tank 2 during stirring, leading to poor mixing of the raw materials and a decrease in the quality of the gold paste. Therefore, with the cooperation of the guide assembly and the enhanced stirring mechanism, the first stirring blade 31 can be controlled to move in a direction away from each other and abut against the inner wall of the processing tank 2 to scrape off the viscous substances on the inner wall. When gold paste needs to be prepared, the raw materials can be added into the processing tank 2 according to the specified ratio, and under the action of the drive assembly, the trigger transmission mechanism is driven to rotate, causing the second stirring blade 37 to rotate. Simultaneously, the trigger transmission mechanism... The mechanism also drives the enhanced stirring mechanism to rotate the first stirring blade 31, thereby comprehensively stirring the material in the processing tank 2. Under the action of the guiding component, the enhanced stirring mechanism can also drive the first stirring blade 31 to move towards or away from each other, so that the first stirring blade 31 intermittently abuts against the inner wall of the processing tank 2, thereby scraping off the material adhering to the inner wall of the processing tank 2. While the first stirring blade 31 is moving, under the action of the reciprocating oscillating component, the first stirring blade 31 is oscillating back and forth at a certain angle to enhance the mixing effect of the raw materials. The drive component also drives the coaxial reversing component to move, so that the guiding component makes intermittent and irregular movements, thereby ensuring that the first stirring blade 31 can comprehensively scrape the inner wall of the processing tank 2. When the material in the processing tank 2 is mixed, the resistance of the first stirring blade 31 and the second stirring blade 37 will decrease. Under the action of the trigger transmission mechanism, this information can be released to prevent the raw materials from being over-stirred, resulting in poor quality.

[0031] A support 1 is provided, on which a processing tank 2 is fixedly installed. A fixing plate 3 is fixedly installed on the top of the processing tank 2, and a baffle 4 is fixedly installed on the fixing plate 3. Please see Figures 1-4 , Figure 7 , Figure 9A drive assembly is mounted on the fixed plate 3 and connected to the processing tank 2. The drive assembly includes a motor 5 fixedly mounted on the fixed plate 3. A transmission rod 6 is rotatably mounted on the fixed plate 3, passing through the processing tank 2 and connected to the output shaft of the motor 5. A fixed limiting tooth 18 is fixedly mounted on the transmission rod 6. The transmission rod 6 is connected to the coaxial reverse assembly and the guide assembly. The fixed limiting tooth 18 is connected to the trigger transmission mechanism.

[0032] In detail, when preparing the modified gold paste, various raw materials need to be added to the processing tank 2 according to the formula. The raw materials include resin, organometallic compounds and other substances. The raw materials in the processing tank 2 are stirred. At this time, the motor 5 works and drives the transmission rod 6 to rotate, which in turn drives the fixed limiting tooth 18 to rotate. Under the action of the fixed limiting tooth 18, the trigger transmission mechanism is activated, thereby controlling the rotation of the second stirring blade 37. Under the action of the second stirring blade 37, the raw materials in the processing tank 2 are mixed.

[0033] Please see Figure 3-5 , Figure 7 , Figure 9 The processing tank 2 is equipped with a trigger transmission mechanism connected to the drive assembly. The processing tank 2 also has symmetrically arranged second stirring blades 37 connected to the trigger transmission mechanism. The drive assembly can drive the second stirring blades 37 to move via the trigger transmission mechanism to stir the material in the processing tank 2. The trigger transmission mechanism includes a rotating rod 19 rotatably installed inside the processing tank 2. A movable rod 20 is movably installed inside the rotating rod 19. A movable limiting tooth 21 is fixed at the end of the movable rod 20 away from the rotating rod 19. The processing tank 2 is equipped with a mechanism connected to the rotating rod... The rotating rod 19 is connected to the movable rod 20 via an elastic component. The fixed limiting tooth 18 engages with the movable limiting tooth 21. The rotating rod 19 is connected to the enhanced stirring mechanism and fixedly connected to the second stirring blade 37. The elastic component includes a fixed ring 22 fixedly installed on the rotating rod 19. Springs 23 are sleeved on the rotating rod 19 and the movable rod 20. A stationary contact 24 is fixed on the fixed limiting tooth 18. A movable contact 25 that cooperates with the stationary contact 24 is fixed on the movable limiting tooth 21. The two ends of the spring 23 abut against the movable limiting tooth 21 and the fixed ring 22, respectively.

[0034] It should be noted that the inner wall of the rotating rod 19 has a slot, and the outer wall of the movable rod 20 has a protruding rod that engages with the slot. This allows the movable rod 20 to rotate synchronously with the rotating rod 19. Since the raw materials for preparing the modified gold paste contain multiple highly viscous substances such as resin, the first stirring blade 31 experiences significant resistance during the stirring process. Initially, the spring 23 is compressed, causing the movable rod 20 to be at the end of its stroke away from the rotating rod 19, and the movable limiting tooth 21 to fully engage with the fixed limiting tooth 18. The moving contact 25 and the stationary contact 24 are in contact. When the raw materials need to be mixed, the motor 5 operates, causing the fixed limiting tooth 18 to rotate, which in turn drives the movable limiting tooth 21 to rotate, causing the movable rod 20 to rotate. Under the action of the slot and the protruding rod, the rotating rod 19 rotates synchronously. The rotating rod 19 also drives the second stirring blade 37 to rotate, thereby stirring the raw materials in the processing tank 2.

[0035] Preferably, since the second stirring blade 37 experiences greater resistance in the initial stage of stirring, a certain misalignment difference will occur between the fixed limiting tooth 18 and the movable limiting tooth 21, compressing the spring 23 and causing the moving contact 25 to separate from the stationary contact 24. As the degree of mixing between materials increases, the misalignment difference between the fixed limiting tooth 18 and the movable limiting tooth 21 gradually decreases until the material mixing is complete. At this point, the viscosity of the material will decrease, the resistance experienced by the second stirring blade 37 during stirring will decrease, the spring 23 will elastically release, causing the movable rod 20 to reset and eliminating the misalignment difference between the movable limiting tooth 21 and the fixed limiting tooth 18. The moving contact 25 will then move back to the position of contacting the stationary contact 24. Under the action of the moving contact 25 and the stationary contact 24, a signal can be released to the information receiving unit to remind the staff that the modified gold paste preparation is complete, ensuring that the modified gold paste will not suffer from poor quality due to over-stirring. The information receiving unit is used to receive the information sent by the contacts, which is an application of the prior art and will not be elaborated upon in this application.

[0036] Also includes: Please see Figure 3 , Figure 5 , Figure 6 , Figure 10An enhanced stirring mechanism is provided inside the processing tank 2 and connected to the trigger transmission mechanism. The processing tank 2 also includes a first stirring blade 31 symmetrically arranged and connected to the enhanced stirring mechanism. The trigger transmission mechanism can drive the first stirring blade 31 to move via the enhanced stirring mechanism. The enhanced stirring mechanism includes a support sleeve 26 fixedly mounted on the rotating rod 19 and symmetrically arranged. A support rod 29 is movably mounted inside the support sleeve 26, and a movable ring 32 is movably mounted on the support rod 29. The processing tank 2 is provided with a connection between the movable ring 32 and the rotating rod 19. The sliding assembly is connected to the guide assembly, the support sleeve 26 is connected to the reciprocating oscillating assembly, and the support rod 29 is fixedly connected to the first stirring blade 31. The sliding assembly includes a receiving plate 34 fixedly installed on the rotating rod 19. The receiving plate 34 has symmetrically arranged sliding grooves 35. A sliding block 36 is slidably installed in the sliding grooves 35. The movable ring 32 is fixedly equipped with symmetrically arranged limiting rods 33. One limiting rod 33 is fixedly connected to the sliding block 36, and the other limiting rod 33 is connected to the guide assembly.

[0037] Furthermore, during the preparation of modified gold paste, the resin and other highly viscous raw materials may adhere to the inner wall of the processing tank 2 during the stirring process, resulting in incomplete mixing of the raw materials. Therefore, it is necessary to scrape off these raw materials during the stirring process. In the initial state, under the action of the guiding component, the movable ring 32 is controlled by the limiting rod 33 to be at the end of its stroke towards the support sleeve 26, so that the support rod 29 is at the end of its stroke inside the support sleeve 26. When the transmission rod 6 rotates, it drives the rotating rod 19 to rotate synchronously, thereby driving the second stirring blade 37 to rotate. At the same time, the rotating rod 19 also drives the support sleeve 26 to move, thereby driving the first stirring blade 31 to rotate through the support rod 29. The second stirring blade 37 mainly turbulently stirs the raw materials at the center of the processing tank 2, while the first stirring blade 31 mainly turbulently stirs the raw materials near the outer wall of the processing tank 2, thereby ensuring a better stirring effect on the raw materials.

[0038] Preferably, the support rod 29 also drives the movable ring 32 to move, causing the limiting rod 33 to move. Under the action of the guiding component, the limiting rod 33 is driven to move, causing the sliding block 36 to move along the length direction of the slide groove 35. The limiting rod 33 also drives the movable ring 32 to move, causing the support rod 29 to move away from the support sleeve 26, so that the first stirring blade 31 moves towards the inner wall of the processing tank 2. When the limiting rod 33 moves to the end of its stroke, the first stirring blade 31 just moves to the position of abutting against the inner wall of the processing tank 2. The first stirring blade 31 is always rotating, thereby scraping the inner wall of the processing tank 2. After scraping a certain area, the limit rod 33 is reset under the action of the guide component, thereby controlling the support rod 29 to return to the support sleeve 26 through the movable ring 32. The above steps are repeated to achieve the effect of scraping the inner wall of the processing tank 2, ensuring more complete mixing of raw materials. When the first stirring blade 31 moves, it can also increase the stirring range of the raw materials in the processing tank 2, so as to further enhance the stirring effect of the raw materials.

[0039] Please see Figure 3 , Figures 5-8 A guiding component is disposed inside the processing tank 2 and connected to the enhanced stirring mechanism and the drive component. The guiding component can guide the first stirring blade 31 to move toward or away from each other through the enhanced stirring mechanism. The guiding component includes a movable sleeve 13 movably mounted on the rotating rod 19. A turntable 14 is fixed to one end of the movable sleeve 13 facing the processing tank 2. A first arc-shaped groove 15 is formed on the side of the turntable 14 away from the movable sleeve 13. An inclined groove 16 communicating with the first arc-shaped groove 15 is also formed on one side of the turntable 14. A second arc-shaped groove 17 communicating with the inclined groove 16 is also formed on one side of the turntable 14. The first arc-shaped groove 15, the inclined groove 16, and the second arc-shaped groove 17 are slidably connected to the limiting rod 33. The movable sleeve 13 is connected to the coaxial reversing component.

[0040] Furthermore, the circumferential radius of the first arc groove 15 is smaller than that of the second arc groove 17, and the first arc groove 15 and the second arc groove 17 are connected by the inclined groove 16. Initially, the limiting rod 33 is located in the middle of one of the first arc grooves 15. Under the action of the movable ring 32, the support rod 29 is positioned at the end of its stroke within the support sleeve 26. When the rotating rod 19 rotates, it drives the limiting rod 33 to rotate around the rotating rod 19. The limiting rod 33 will also slide within the first arc groove 15. At this time, the position of the support rod 29 within the support sleeve 26 will not move. When the limiting rod 33 enters the inclined groove 16, it will drive the support rod 29 along the support through the movable ring 32. The support sleeve 26 moves in the direction away from the support sleeve 26, thereby driving the first stirring blade 31 to move towards the inner wall of the processing tank 2. When the limiting rod 33 moves into the second arc groove 17, the first stirring blade 31 just moves to abut against the inner wall of the processing tank 2 and scrapes off the material adhering to the inner wall. When the limiting rod 33 moves into the inclined groove 16 again, the first stirring blade 31 moves towards the support sleeve 26 until the limiting rod 33 moves into the first arc groove 15, and the support rod 29 resets. The above steps are repeated to achieve the operation of scraping off the material adhering to the inner wall of the processing tank 2 while mixing the raw materials in the processing tank 2, so as to ensure that the raw materials are completely mixed.

[0041] Please see Figure 7 , Figure 10 The processing tank 2 is also provided with a reciprocating oscillating assembly connected to the enhanced stirring mechanism. The reciprocating oscillating assembly can move when the enhanced stirring mechanism moves and drive the first stirring blade 31 to perform a reciprocating oscillating motion. The reciprocating oscillating assembly includes a guide groove 27 formed in the inner wall of the support sleeve 26. The inner wall of the support sleeve 26 is also provided with a straight groove 28 that communicates with the guide groove 27. A protrusion 30 is fixed on the support rod 29 and is slidably connected to the guide groove 27 and the straight groove 28.

[0042] To elaborate, in order to enhance the mixing effect of the raw materials, the first stirring blade 31 can be controlled to reciprocate and oscillate while moving along the length of the support sleeve 26. In the initial state, the protrusion 30 is located at the end of the stroke on one side of the guide groove 27, which is arranged in a spiral wave shape. When the support rod 29 moves along the length of the support sleeve 26, it drives the protrusion 30 to slide in the guide groove 27, causing the support rod 29 with the protrusion 30 fixed to it to rotate at a certain angle, thereby controlling the first stirring blade 31 to reciprocate and oscillate at a certain angle until the protrusion 30... When the first stirring blade 31 moves into the straight groove 28, it will also move to the position of contact with the inner wall of the processing tank 2. At this time, the first stirring blade 31 will no longer wobble to prevent interference between the first stirring blade 31 and the processing tank 2. When the protrusion 30 moves to the end of the stroke of the straight groove 28, the first stirring blade 31 moves to the position of contact with the inner wall of the processing tank 2. When the support rod 29 moves toward the support sleeve 26, the protrusion 30 will move along the trajectory of the straight groove 28 and the guide groove 27 again, repeating the above steps to control the stirring range of the first stirring blade 31 to be larger.

[0043] Please see Figures 1-3 , Figure 5 , Figure 8 A coaxial reversing assembly is disposed on the baffle 4 and connected to the drive assembly and the guide assembly. The coaxial reversing assembly can operate when the drive assembly moves and control the movement of the enhanced stirring mechanism through the guide assembly to regulate the movement trajectory of the first stirring blade 31. The coaxial reversing assembly includes an incomplete gear ring 7 fixedly mounted on the transmission rod 6. A first pinion 8 that meshes with the incomplete gear ring 7 is rotatably mounted on the baffle 4. A second pinion 9 that meshes with the first pinion 8 is also rotatably mounted on the baffle 4. The coaxial reversing assembly also includes a support slide rail 10 fixedly mounted on the top of the processing tank 2. A sliding ring 11 is slidably mounted in the support slide rail 10. A fully gear ring 12 that meshes with the second pinion 9 is fixed on the sliding ring 11. The fully gear ring 12 is fixedly connected to the movable sleeve 13.

[0044] It should be noted that if the limiting rod 33 moves along the trajectory of the first arc groove 15, the inclined groove 16, and the second arc groove 17, the position where the first stirring blade 31 contacts the inner wall of the processing tank 2 will always be only a few fixed points. This will result in residual material remaining on the inner wall of the processing tank 2. Therefore, it is necessary to adjust the contact position between the first stirring blade 31 and the inner wall of the processing tank 2. When the transmission rod 6 rotates, it drives the incomplete gear ring 7 to rotate. The incomplete gear ring 7 has a toothed part and a toothless part. When the toothed part meshes with the first pinion 8, the first pinion 8 rotates, thereby driving the second pinion 9, which meshes with it, to rotate, so that the fully toothed part meshing with the second pinion 9... As ring 12 rotates, since the number of teeth in the fully geared ring 12 is greater than that in the partially geared ring 7, the rotational speed of the fully geared ring 12 will be less than that of the transmission rod 6. The fully geared ring 12 will also drive the movable sleeve 13 to rotate, thereby driving the turntable 14 to rotate, so as to change the contact position between the first stirring blade 31 and the inner wall of the processing tank 2. When the toothed part of the partially geared ring 7 separates from the first pinion 8, the toothless part will face the first pinion 8. At this time, the fully geared ring 12 remains stationary, so that the turntable 14 will not rotate. Repeat the above steps to intermittently and irregularly change the angle of the turntable 14, so that the first stirring blade 31 can thoroughly scrape the inner wall of the processing tank 2.

[0045] A process for preparing a modified gold paste for thermal printing sheets includes the following steps: Step 1: Weigh the raw materials according to the proportions and add them into processing tank 2 in sequence; Step 2: Under the action of the drive component, the second stirring blade 37 is controlled to rotate by triggering the transmission mechanism. The triggering transmission mechanism will also drive the enhanced stirring mechanism to rotate, so that the first stirring blade 31 rotates to mix the raw materials in the processing tank 2. Step 3: In order to prevent the sticky material contained in the raw materials from adhering to the inner wall of the processing tank 2 and causing uneven mixing, under the action of the guiding component, the first stirring blade 31 is controlled to move towards the inner wall of the processing tank 2 by the enhanced stirring mechanism, and under the action of the reciprocating oscillating component, the first stirring blade 31 is controlled to oscillate back and forth at a certain angle until the first stirring blade 31 comes into contact with the inner wall of the processing tank 2, thereby scraping off the adhering raw materials; Step 4: The drive component can also drive the guide component to move through the coaxial reversing component, so that the first stirring blade 31 can completely scrape off the adhering raw materials. As the raw materials are mixed more thoroughly, the resistance of the first stirring blade 31 and the second stirring blade 37 is reduced, which triggers the transmission mechanism to work and sends a signal to remind the staff that the modified gold paste preparation is complete, thereby avoiding the problem of poor quality of modified gold paste due to over-stirring.
