Technical Field

[0001] The invention relates to the technical field of resin preparation, and in particular to a preparation device and a preparation process for a modified resin. Background Art

[0002] The most important application of modified resin is the manufacture of plastics. In order to facilitate processing and improve performance, additives are often added, and sometimes they are directly used for processing and forming, so they are often synonymous with plastics. Modified resin is also the basic raw material for the manufacture of synthetic fibers, coatings, adhesives, insulating materials, etc. There are many types of modified resins, among which polyethylene (PE), polyvinyl chloride (PVC), polystyrene (PS), polypropylene (PP) and ABS resin are the five general-purpose resins and the most widely used modified resin materials.

[0004] During the preparation process of modified resin, different additives need to be added in sequence at different times. Existing preparation devices add additives directly to the surface of the material from above. However, when the material gradually becomes viscous, the added additives will accumulate on the upper surface of the material. The stirring shaft needs to be stirred for a long time to evenly stir the upper additives in the material, which increases the stirring time and may cause insufficient stirring of the added additives. Summary of the invention

[0005] The present invention provides a mixing device and a mixing process for a modified resin, aiming to solve the problem in the related art that different additives need to be added in sequence at different times during the mixing process of the modified resin. The existing mixing devices all add additives directly to the surface of a material from above, but when the material gradually becomes viscous, the added additives will accumulate on the upper surface of the material, and a stirring shaft needs to be stirred for a long time to evenly stir the additives in the upper layer in the material, which increases the stirring time and may lead to a technical problem that the added additives are not stirred sufficiently.

[0006] The invention provides a mixing device for modified resin, comprising: a mixing barrel and a stirring shaft, wherein a material storage box is arranged on the mixing barrel, a ring is provided at the bottom of the material storage box, a swivel is slidably fitted on the ring, a material discharge hole is provided on the swivel, a top seat is fixedly installed at the bottom of the swivel, a material discharge ball is rotatably installed on the top seat, through holes are provided on the top seat and the material discharge ball, and are communicated with the material discharge hole, a telescopic tube is also connected below the material discharge ball, the telescopic tube is formed by sealing and sliding fitting of a plurality of telescopic units, a material discharge seat is communicated at the bottom of the telescopic tube, a material discharge barrel is rotatably installed at the bottom of the material discharge seat, movable grooves are provided on the opposite sides of the material discharge seat, a driving rod is slidably fitted in the movable groove, an elastic member is also provided in the movable groove, one end of the driving rod on one side away from the movable groove is vertically slidably fitted with the stirring shaft, a driving groove is provided on the inner wall of the mixing barrel, the driving groove is wavy, one end of the driving rod on the other side away from the movable groove is located in the driving groove, a transmission assembly is also provided on the stirring shaft, the transmission assembly is connected with the material discharge barrel, and the material discharge barrel can be rotated when the material discharge seat is lifted or lowered.

[0007] Beneficial effect: When the stirring shaft rotates to stir the material, it can drive the discharge seat to rotate around the axial direction of the mixing barrel. The discharge seat simultaneously drives the swivel, the top seat, the discharge ball and the telescopic tube to rotate synchronously. While rotating, the driving rod continuously moves along the driving groove, which can force the discharge seat to continuously rise and fall, so that the additives can be evenly scattered to different heights of the material. With the addition of additives, the viscosity of the material increases, and the rotational resistance of the discharge seat becomes larger. When its rotational resistance is greater than the elastic force of the elastic member, the discharge seat, the telescopic tube and the discharge ball will rotate together, and the elastic member is compressed, so that the through hole connecting the top seat and the discharge ball becomes smaller, thereby reducing the speed of adding additives, so that the additives can be stirred more fully in the viscous material.

[0008] Preferably, the transmission assembly includes a rack fixedly mounted on the stirring shaft, and a gear meshing with the rack is connected to the discharge barrel.

[0009] The effect is that when the discharging seat is lifted and lowered along the stirring shaft, the discharging barrel is driven to rotate through the rack and the gear.

[0010] Preferably, a mounting groove is provided on the side wall of the discharge seat, and the mounting groove is close to the bottom opening of the discharge seat. A discharge groove is provided on the outer side of the discharge barrel. The discharge groove is an arc-shaped structure, and the axis of the discharge groove is parallel to the axis of the discharge barrel. The opening of the mounting groove is opposite to the discharge groove on the discharge barrel. A scraper plate is slidably installed in the mounting groove, and a spring is arranged on the scraper plate.

[0011] The effect is that since the discharge barrel is located in the material, the discharge chute can deliver the additive during its rotation, but when the discharge chute rotates upward again and returns to the discharge seat, the material will be brought into the discharge seat. Therefore, the scraper plate can continuously scrape the discharge chute to prevent the material from entering the discharge seat.

[0012] Preferably, a material storage box is fixedly installed on the side wall of the mixing barrel, and a plurality of partitions are arranged at intervals on the inner side of the material storage box, which divides the inner side into a plurality of material storage chambers, and a discharge valve is arranged at the bottom of each material storage chamber, and a discharge pipe is connected to the bottom of the material storage box.

[0013] Preferably, a push plate is fixedly mounted on the rotating ring, the push plate is arranged in a V shape, and the opening of the push plate faces the discharge hole, and the two ends of the push plate are slidably matched with the front and rear side walls inside the storage box.

[0014] The effect is that when the push plate rotates, the additive can be continuously pushed to the discharge hole, so that the additive can fall downward.

[0015] Preferably, the movable groove is an arc-shaped structure, and the elastic member is a spring, and one end of the elastic member abuts against the driving rod.

[0016] Preferably, the telescopic tube is fixedly installed with a filter screen near the bottom position, a fixing column is fixedly installed on the filter screen, a fixing plate is fixedly installed on the outer wall of the fixing column, and a swivel seat is rotatably installed on the upper end of the fixing column, a splint is fixedly installed on the swivel seat, the splint and the fixing plate are both arranged along the radial direction of the filter screen, a through hole is opened on the swivel seat, a spiral rod is fitted in the through hole, a magnet is fixedly installed on the upper end of the spiral rod, a top plate is fixedly installed near the top position of the telescopic tube, and a square groove is opened on the lower end surface of the top plate.

[0017] The effect is that during the storage of the additive, moisture nodules may appear. Once the agglomerated material is added to the viscous material, it is difficult to stir it. Therefore, the telescopic characteristics of the telescopic tube are utilized to allow the splint to continuously squeeze the additive to avoid the agglomeration of the additive.

[0018] Preferably, a method for preparing a modified resin, using the above-mentioned modified resin preparation device, comprises the following steps: Step 1, add the additive into the storage box; Step 2: inject the stock solution into the mixing barrel, and start stirring by rotating the stirring shaft; Step 3: During the rotation of the stirring shaft, the driving rod connected to the stirring shaft can drive the discharging seat to rotate synchronously. During the rotation of the discharging seat, it will reciprocate up and down along the stirring shaft, the discharging barrel will continuously rotate, and the additive will fall into the discharging seat through the telescopic tube. As the discharging barrel rotates, the additive will be continuously brought into the material for mixing; Step 4: As the viscosity of the material increases, the resistance to rotation of the discharge seat and the telescopic tube in the material increases. When the resistance to rotation is greater than the elastic force of the elastic member, the elastic member will be gradually compressed, and the discharge seat will rotate along the moving groove. When the discharge seat rotates, the telescopic tube and the discharge ball will be driven to rotate together, and the through hole connecting the top seat and the discharge ball will become smaller, thereby reducing the speed of adding the additive. Step 5: After the resin is mixed, discharge the resin.

[0019] The effect is that the additive is discharged from the discharge barrel into the material in the mixing barrel after passing through the top seat, the discharge ball and the telescopic tube. When the stirring shaft rotates to stir the material, it can drive the discharge seat to rotate around the axial direction of the mixing barrel. The discharge seat simultaneously drives the swivel, the top seat, the discharge ball and the telescopic tube to rotate synchronously. While rotating, the driving rod continuously moves along the driving groove, which can force the discharge seat to continuously rise and fall, so that the additive can be evenly scattered to different heights of the material. With the addition of the additive, the viscosity of the material begins to increase, and the rotational resistance of the discharge seat becomes larger. When the rotational resistance is greater than the elastic force of the elastic member, the discharge seat, the telescopic tube and the discharge ball will rotate together, and the elastic member will be compressed, so that the through hole connecting the top seat and the discharge ball becomes smaller, thereby reducing the speed of adding the additive, so that the additive can be stirred more fully in the viscous material.

[0020] By adopting the above technical scheme, the beneficial effects of the present invention are as follows: the stirring shaft can drive the discharge seat to rotate around the axial direction of the mixing barrel, and the discharge seat can be continuously raised and lowered, so that the additive can be evenly scattered to different heights of the material. When the viscosity of the material increases, the rotational resistance of the discharge seat becomes larger. When its rotational resistance is greater than the elastic force of the elastic member, the discharge seat, the telescopic tube and the discharge ball will rotate together, and the elastic member will be compressed, so that the through hole connecting the top seat and the discharge ball becomes smaller, reducing the speed of adding the additive, so that the additive can be more fully stirred in the viscous material. At the same time, it can improve the stirring efficiency and shorten the stirring time. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] like Figures 1 to 10 As shown, a specific embodiment of a modified resin mixing device and mixing process of the present invention includes a mixing barrel 10, a stirring shaft 11, a driving groove 14, a material storage box 20, a material storage box 30, a rotating ring 31, a top seat 33, a discharge ball 34, a telescopic tube 35, a discharge seat 40, a discharge barrel 41, a movable groove 42, an elastic member 43 and a driving rod 44.

[0034] The stirring shaft 11 is rotatably installed in the mixing barrel 10 , and the driving groove 14 is wave-shaped and is arranged around the inner wall of the mixing barrel 10 .

[0035] The material storage box 20 and the material storage box 30 are installed above the mixing barrel 10. The material storage box 20 can be loaded with a variety of additives, and the additives can be added into the material storage box 30. A swivel 31 is rotatably installed on the material storage box 30. The swivel 31 is in the shape of a boss, and a feed hole is opened on the swivel 31. The width of the raised portion of the swivel 31 is slightly larger than the diameter of the feed hole, and the upper surface of the raised portion is flush with the bottom wall inside the material storage box 30.

[0036] A top seat 33 is fixedly mounted at the bottom of the rotating ring 31 , and a feeding ball 34 is rotatably mounted on the top seat 33 . Both the top seat 33 and the feeding ball 34 are provided with through holes that are connected to the feeding hole on the rotating ring 31 . A telescopic tube 35 is also connected below the feeding ball 34 .

[0037] A discharge seat 40 is installed at the lower end of the telescopic tube 35 , and a discharge barrel 41 is rotatably installed at the bottom of the discharge seat 40 . The additive can pass through the telescopic tube 35 and enter the material in the mixing barrel 10 from the discharge barrel 41 .

[0038] Movable grooves 42 are provided on both sides of the discharge seat 40, and driving rods 44 are slidably installed in the movable grooves 42. Elastic parts 43 are also provided in the movable grooves 42. The driving rod 44 on one side of the discharge seat 40 slides with the stirring shaft 11, and the driving rod 44 on the other side extends into the driving groove 14, so that the stirring shaft 11 can drive the discharge seat 40 to rotate. At the same time, the driving groove 14 can force the discharge seat 40 to rise and fall continuously, so that the additives can be evenly scattered to different heights of the material.

[0039] When the viscosity of the material increases, the rotation resistance of the discharge seat 40 becomes larger, the discharge seat 40, the telescopic tube 35 and the discharge ball 34 will rotate together, and the elastic member 43 will be compressed, so that the through hole connecting the top seat 33 and the discharge ball 34 becomes smaller, reducing the speed of adding the additive.

[0040] During operation, the storage box 20 can add the additives into the storage box 30 in sequence, and the additives are discharged from the discharge barrel 41 to the materials in the mixing barrel 10 after passing through the top seat 33, the discharge ball 34 and the telescopic tube 35. While the stirring shaft 11 rotates to stir the materials, it can drive the discharge seat 40 to rotate around the axial direction of the mixing barrel 10. The discharge seat 40 synchronously drives the rotating ring 31, the top seat 33, the discharge ball 34 and the telescopic tube 35 to rotate synchronously. While rotating, the driving rod 44 continuously moves along the driving groove 14, which can force the discharge The material seat 40 is continuously raised and lowered, so that the additive can be evenly scattered to different heights of the material. With the addition of the additive, the viscosity of the material begins to increase, and the rotational resistance of the discharge seat 40 becomes larger. When its rotational resistance is greater than the elastic force of the elastic member 43, the discharge seat 40, the telescopic tube 35 and the discharge ball 34 will rotate together, and the elastic member 43 is compressed, so that the through hole connecting the top seat 33 and the discharge ball 34 becomes smaller, reducing the speed of adding the additive, so that the additive can be stirred more fully in the viscous material.

[0041] like Figure 1 and Figure 2 A stirring shaft 11 is rotatably installed inside the mixing barrel 10, and the stirring shaft 11 is driven by a motor. A discharge valve 12 is installed at the bottom of the mixing barrel 10. A liquid inlet pipe 13 is connected to the outer wall of the mixing barrel 10 near the top. The raw liquid can be added to the mixing barrel 10 through the liquid inlet pipe 13, or after the work is completed, water can be injected into the mixing barrel 10 through the liquid inlet pipe 13 for cleaning.

[0042] A driving groove 14 is formed on the inner wall of the mixing barrel 10. The driving groove 14 is wavy (eg Figure 2), when the discharging seat rotates 40 times, it can be continuously raised and lowered, and how to achieve the lifting and lowering will be described in detail later.

[0043] The storage box 20 is fixedly installed on the side wall of the mixing barrel 10, and a plurality of partitions 21 are arranged at intervals on the inner side of the storage box 20. The partitions 21 divide the inner side into a plurality of storage chambers, which can be loaded with different types of additives, and a discharge valve 22 is arranged at the bottom of each storage chamber, and specific additives can be added as needed. A discharge pipe 23 is connected to the bottom of the storage box 20, and the additives in the storage chamber can be discharged through the discharge pipe 23.

[0044] like Figure 1 and Figure 7 A material storage box 30 is fixedly installed on the upper end of the mixing barrel 10 , and the discharge port of the discharge pipe 23 faces the material storage box 30 , so that the auxiliary agent in the storage box 20 can be added into the material storage box 30 .

[0045] The material storage box 30 is coaxially arranged with the mixing barrel 10, and an annular groove extending vertically through the material storage box 30 is provided at the bottom thereof. A rotating ring 31 is also provided at the bottom thereof for sliding engagement. The rotating ring 31 is in the shape of a boss. The raised portion of the rotating ring 31 extends upward into the annular groove on the material storage box 30, and the raised portion of the rotating ring 31 slides in engagement with the annular groove, and the upper surface of the raised portion is flush with the bottom wall of the inner side of the material storage box 30 (e.g., Figure 3 ). A feeding hole is provided on the raised portion of the rotating ring 31, and the width of the raised portion of the rotating ring 31 is slightly larger than the diameter of the feeding hole, so as to ensure that the additive can be discharged from the feeding hole during the rotation of the rotating ring 31.

[0046] A push plate 32 is fixedly installed on the upper surface of the raised portion of the rotating ring 31 and near the discharge hole. The push plate 32 is arranged in a V shape, and the opening of the push plate 32 faces the discharge hole. The two ends of the push plate 32 slide with the opposite side walls on the inner side of the storage box 30. When the rotating ring 31 and the push plate 32 rotate, the auxiliary agent in the storage box 30 is in a static state relative to the rotating ring 31, so the push plate 32 can continuously gather the auxiliary agent to the middle when it rotates, so that the auxiliary agent can be discharged from the discharge hole.

[0047] like Figure 2 , Figure 3 and Figure 5 A top seat 33 is fixedly installed at the bottom of the rotating ring 31, and the top seat 33 is connected with the discharge hole on the rotating ring 31. A discharge ball 34 is rotatably installed inside the top seat 33. The discharge ball 34 is a spherical structure. Circular through holes are opened on the top seat 33 and the discharge ball 34, and the through holes of the two are connected to ensure that the additive can fall after passing through the through holes.

[0048] When the lower material ball 34 rotates, the through hole between the two will be misaligned (such as Fig.10), at this time, the area of ​​the connection between the top seat 33 and the discharge ball 34 will become smaller, which can reduce the amount of the auxiliary agent falling.

[0049] like Figure 5 A telescopic tube 35 is connected below the feeding ball 34. The telescopic tube 35 is composed of a plurality of telescopic units. The plurality of telescopic units are sealed and slidably connected to each other. In this embodiment, the telescopic units are all circular tubular structures.

[0050] Continue back Figure 5 and Figure 6 The lower end of the telescopic tube 35 is fixedly installed with a discharge seat 40 connected thereto. The discharge seat 40 is a bottom opening structure, and a discharge barrel 41 is rotatably installed at the bottom. The lower half of the discharge barrel 41 protrudes from the lower end surface of the discharge seat 40, and a discharge trough is provided on the outer side surface of the discharge barrel 41. The discharge trough is an arc structure, and the axis of the discharge trough is parallel to the axis of the discharge barrel 41. During the rotation of the discharge barrel 41, the auxiliary agent that falls into the discharge seat 40 through the telescopic tube 35 will fall into the discharge trough above the discharge barrel 41. As the discharge barrel 41 rotates, the discharge trough rotates to the bottom with the auxiliary agent, and the auxiliary agent enters the material and is mixed.

[0051] like Figure 6 A gear 45 is connected to the lower barrel 41, and a rack 46 meshing with the gear 45 is fixedly installed on the side of the stirring shaft 11. When the discharge seat 40 is continuously raised and lowered, the lower barrel 41 can be driven to rotate continuously through the gear 45.

[0052] Since the discharge barrel 41 is located in the material, the discharge chute can deliver the additive during its rotation. However, when the discharge chute rotates upward again and returns to the discharge seat 40, the material will be brought into the discharge seat 40. In order to solve this problem, a scraper plate 51 is also installed on the discharge seat 40 to scrape the discharge chute, which will be explained in detail below.

[0053] like Fig. 9 A mounting groove 50 is provided on a side wall of the discharge seat 40 which is consistent with the axial direction of the discharge barrel 41, and the mounting groove 50 is close to the bottom opening of the discharge seat 40. The opening of the mounting groove 50 is opposite to the discharge groove on the discharge barrel 41. A scraper plate 51 is slidably installed in the mounting groove 50. A spring is arranged on the scraper plate 51. When the spring is released, the scraper plate 51 extends to the outside of the mounting groove 50. Therefore, when the discharge barrel 41 rotates, the scraper plate 51 can continuously contact the discharge groove on the discharge barrel 41. As the curvature of the discharge groove changes, the scraper plate 51 continuously slides back and forth in the mounting groove 50. The scraper plate 51 can continuously scrape the discharge groove that returns to the discharge seat 40 after discharging the auxiliary agent, so as to avoid bringing the material into the discharge seat 40.

[0054] Continue back Figure 4 , Figure 5 and Figure 6 , arc-shaped moving grooves 42 are provided on both sides of the discharge seat 40, and driving rods 44 are provided in the moving grooves 42. Elastic parts 43 are also installed in the moving grooves 42. In this embodiment, the elastic part 43 is a spring. When the spring is released, one end abuts against the driving rod 44, and one end of the driving rod 44 on one side away from the moving groove 42 is located in the driving groove 14. A sliding groove 47 is vertically provided on the side of the stirring shaft 11, and one end of the driving rod 44 on the other side away from the moving groove 42 is located in the sliding groove 47. Therefore, when the stirring shaft 11 rotates, the driving rod 44 connected to the stirring shaft 11 can drive the discharge seat 40 to rotate synchronously. Since the driving rod 44 on the other side is located in the driving groove 14, the driving groove 14 is wavy, so when the discharge seat 40 rotates, it will be forced to rise and fall continuously with the driving groove 14, and the sliding groove 47 can ensure that the discharge seat 40 slides up and down along the stirring shaft 11.

[0055] During the rotation of the discharge seat 40, the telescopic tube 35, the top seat 33, the discharge ball 34 and the rotating ring 31 will be driven to rotate synchronously. When the discharge seat 40 is raised or lowered, the telescopic tube 35 will be driven to extend or contract, so that the auxiliary agent is discharged from different heights in the material after being discharged. As the material is stirred, the auxiliary agent can be fully mixed in the material.

[0056] Under normal conditions, when the stirring shaft 11 drives the discharge seat 40 to rotate, the viscosity of the material is not too large. However, with the addition of additives, the viscosity of the material increases. Therefore, when the discharge seat 40 and the telescopic tube 35 rotate in the material, the resistance will become greater. When the resistance to its rotation is greater than the elastic force of the elastic member 43, the elastic member 43 will gradually be compressed, and the driving rods 44 on both sides are respectively restricted by the driving groove 14 and the slide groove 47, so the discharge seat 40 will rotate at a certain angle along the movable groove 42.

[0057] When the discharge seat 40 rotates, it will synchronously drive the telescopic tube 35 and the discharge ball 34 to rotate together, and the through hole connecting the top seat 33 and the discharge ball 34 will become smaller (such as Fig.10 As shown in the figure, the speed of adding the additive can be reduced. Because the viscosity of the material increases, when the speed of adding the additive is too fast, it is difficult for the additive to be fully stirred in the viscous material, and it is easy to be distributed in lumps, which increases the stirring time. Therefore, according to the viscosity of the material, the speed of adding the additive is adjusted in real time. When the material is viscous, the speed of adding the additive is reduced, so that the additive can be stirred faster and more fully in the viscous material, avoiding the situation where the additive is stirred unevenly.

[0058] During the storage of the additive, moisture nodules may appear. Once the agglomerated material is added to the viscous material, it is difficult to stir it. Therefore, in order to solve this problem, the present invention also adds a crushing component, which is as follows: like Figure 8 A filter screen 60 is fixedly installed in the lowest section of the telescopic tube 35, a hollow fixed column 61 is fixedly installed at the center of the filter screen 60, a fixed plate 62 is fixedly installed on the outer wall of the fixed column 61, the fixed plate 62 is arranged along the radial direction of the filter screen 60, and a rotating seat 63 is rotatably installed on the upper end of the fixed column 61, a clamping plate 64 is fixedly installed on the rotating seat 63, and the lower end surfaces of the fixed plate 62 and the clamping plate 64 are both slidably matched with the filter screen 60.

[0059] A through hole is provided on the rotating seat 63, in which a screw rod 65 is fitted, and a square magnet 66 is fixedly installed on the upper end of the screw rod 65. A top plate 67 is fixedly installed inside the uppermost section of the telescopic tube 35. The material of the top plate 67 is iron, and a square groove is provided on the lower end surface of the top plate 67.

[0060] When the telescopic tube 35 contracts, the screw rod 65 moves upward until it conflicts with the top plate 67. At this time, the magnet 66 is located in the square groove on the lower end surface of the top plate 67, which can prevent the screw rod 65 from rotating and is adsorbed on the top plate 67. As the telescopic tube 35 continues to contract, the filter screen 60 will continue to rise, and the screw rod 65 will drive the rotating seat 63 and the clamping plate 64 to rotate. When the clamping plate 64 rotates, it will drive the additive to move toward the fixed plate 62 until the screw rod 65 is completely inserted into the inner side of the rotating seat 63 and the fixed column 61, and the clamping plate 64 rotates to the maximum stroke, at which time it just conflicts with the fixed plate 62, thereby squeezing the additive on the fixed plate 62 to crush the additive.

[0061] It is particularly emphasized that both the clamping plate 64 and the fixing plate 62 are provided with filter holes, so that when the auxiliary agent is squeezed, the auxiliary agent can pass through the filter holes to ensure the squeezing effect.

[0062] When the telescopic tube 35 is extended, since the magnet 66 is adsorbed on the top plate 67, the filter screen 60 will first drive the rotating seat 63 to move downward, and the spiral rod 65 will remain stationary. When the rotating seat 63 moves downward, the spiral rod 65 will force the clamping plate 64 to rotate in the opposite direction until the clamping plate 64 rotates to the other side of the fixed plate 62, squeezing the material again. As the rotating seat 63 descends to the maximum stroke of the spiral rod 65, the telescopic tube 35 continues to extend, causing the magnet 66 to disengage from the top plate 67.

[0063] In this reciprocating cycle, the clamping plate 64 is continuously rotated back and forth, pressing the additive onto the fixed plate 62, and crushing the nodules in the additive.

[0064] According to a modified resin preparation device of an embodiment of the present invention, the preparation process thereof includes the following steps: Step 1: Add multiple additives into the material storage box 20, open different discharge valves 22 as needed, and add different additives into the material storage box 30; Step 2: inject the stock solution into the mixing barrel 10, and rotate the stirring shaft 11 to start stirring; Step three, during the rotation of the stirring shaft 11, the driving rod 44 connected to the stirring shaft 11 can drive the discharge seat 40 to rotate synchronously. Since the driving rod 44 on the other side is located in the driving groove 14, and the driving groove 14 is wavy, when the discharge seat 40 rotates, it will be forced to continuously rise and fall with the driving groove 14. The slide groove 47 on the stirring shaft 11 can ensure that the discharge seat 40 slides up and down along the stirring shaft 11. During the continuous lifting of the discharge seat 40, the gear 45 can drive the discharge barrel 41 to continuously rotate. The discharge barrel 41 discharge trough can deliver the additive. The additive falls into the discharge seat 40 through the telescopic tube 35 and will fall into the discharge trough. As the discharge barrel 41 rotates, the discharge trough rotates to the bottom with the additive, and the additive will enter the material for mixing.

[0065] Step 4: As the viscosity of the material increases, the resistance of the discharge seat 40 and the telescopic tube 35 when they rotate in the material will increase. When the resistance to their rotation is greater than the elastic force of the elastic member 43, the elastic member 43 will be gradually compressed, and the discharge seat 40 will rotate along the moving groove 42 at a certain angle. When the discharge seat 40 rotates, the telescopic tube 35 and the discharge ball 34 will be driven to rotate together synchronously, and the through hole connecting the top seat 33 and the discharge ball 34 will become smaller, thereby reducing the speed of adding the additive. Step 5: After the resin is prepared, open the discharge valve 12 to discharge the resin.

[0066] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
