Description

Technical Field

[0001] The present invention relates to the technical field of resin formulation, and particularly relates to a device and a process for formulating modified resin. Background Art

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

[0003] Chinese Patent with the authorization announcement number CN218222109U discloses a device for formulating rosin maleic acid modified resin, including a bottom plate. A stirring device, a feeding device, and a cleaning device are installed on the bottom plate. The stirring device includes a motor and a formulation barrel. The bottom plate is connected to the formulation barrel, and the top of the formulation barrel is connected to the motor. A stirring shaft is arranged inside the formulation barrel, and stirring rods are arranged on the stirring shaft. The feeding device includes a support plate and a first fixing plate. The bottom plate is connected to the support plate, the support plate is connected to the first fixing plate, a fixing hole is opened on the first fixing plate, a feeding barrel is arranged on the fixing hole, a connecting pipe is arranged at the bottom end of the feeding barrel. The cleaning device includes a water tank and a water pump. The bottom plate is connected to the water tank, the water tank is connected to the water pump. One end of the water pump is provided with a first water pipe, the other end of the water pump is provided with a second water pipe. The water pump is connected to the water tank through the first water pipe, and the water pump is connected to the formulation barrel through the second water pipe.

[0004] During the formulation process of modified resin, different additives need to be added in sequence at different times. Existing formulation devices all 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, and it takes a long time for the stirring shaft to stir evenly to mix the upper-layer additives into the material, increasing the stirring time and possibly resulting in insufficient stirring of the added additives. Summary of the Invention

[0005] The present invention provides a device and a process for formulating modified resin, aiming to solve the technical problem that during the formulation process of modified resin, different additives need to be added in sequence at different times. Existing formulation devices all 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, and it takes a long time for the stirring shaft to stir evenly to mix the upper-layer additives into the material, increasing the stirring time and possibly resulting in insufficient stirring of the added additives.

[0006] A device for preparing a modified resin of the present invention includes: a preparation barrel and a stirring shaft. A storage box is arranged on the preparation barrel. The bottom of the storage box has an annular groove. A rotating ring is slidably fitted on the annular groove. A material discharging hole is formed on the rotating ring. A top seat is fixedly installed at the bottom of the rotating ring. A material discharging ball is rotatably installed on the top seat. Through holes are formed on both the top seat and the material discharging ball and are communicated with the material discharging hole. A telescopic pipe is also communicated below the material discharging ball. The telescopic pipe is formed by sealing and sliding cooperation of a plurality of telescopic units. The bottom of the telescopic pipe is communicated with a discharging seat. A material discharging cylinder is rotatably installed at the bottom of the discharging seat. Moving grooves are formed on opposite side surfaces of the discharging seat. Driving rods are slidably fitted in the moving grooves. Elastic members are also arranged in the moving grooves. One end of the driving rod away from the moving groove on one side is vertically slidably fitted with the stirring shaft. A driving groove is arranged on the inner wall of the preparation barrel. The driving groove is in a wave shape. The other end of the driving rod away from the moving groove is located in the driving groove. The stirring shaft is also provided with a transmission component. The transmission component is connected with the material discharging cylinder. When the discharging seat moves up and down, the material discharging cylinder can be rotated.

[0007] Beneficial effects: While the stirring shaft rotates to stir the materials, it can drive the discharging seat to rotate around the axis of the preparation barrel. The discharging seat synchronously drives the rotating ring, the top seat, the material discharging ball and the telescopic pipe to rotate synchronously. During the rotation, the driving rod continuously moves along the driving groove, which can force the discharging seat to continuously move up and down, so that the additives can be evenly scattered at different heights of the materials. As the additives are added, the viscosity of the materials increases, and the rotation resistance of the discharging seat becomes larger. After its rotation resistance is greater than the elastic force of the elastic member, the discharging seat, the telescopic pipe and the material discharging ball will rotate together, and the elastic member is compressed, making the through hole communicated between the top seat and the material discharging ball smaller, reducing the speed of additive addition, so that the additives can be stirred more fully in the viscous materials.

[0008] Preferably, the transmission component includes a rack fixedly installed on the stirring shaft, and a gear engaged with the rack is connected to the material discharging cylinder.

[0009] The effect is that: during the process of the discharging seat moving up and down along the stirring shaft, the material discharging cylinder is driven to rotate through the rack and the gear.

[0010] Preferably, an installation groove is formed on the side wall of the discharging seat, and the installation groove is close to the bottom opening of the discharging seat. Material discharging grooves are arranged on the outer side surface of the material discharging cylinder. The material discharging grooves are in an arc structure, and the axis of the material discharging groove is parallel to the axis of the material discharging cylinder. The opening of the installation groove is directly opposite to the material discharging groove on the material discharging cylinder. A scraping plate is slidably installed in the installation groove, and a spring is arranged on the scraping plate.

[0011] The effect is that: since the material discharging cylinder is located in the materials, when it rotates, the material discharging grooves can send out the additives. However, when the material discharging grooves rotate upward and return to the discharging seat again, the materials will be brought into the discharging seat. Therefore, the scraping plate can continuously scrape the material discharging grooves to prevent the materials from entering the discharging seat.

[0012] Preferably, a storage box is fixedly installed on the side wall of the blending barrel. A plurality of partition plates are arranged at intervals inside the storage box. The partition plates divide the inside thereof into a plurality of storage chambers, and a blanking valve is arranged at the bottom of each storage chamber. A blanking pipe is communicated below the storage box.

[0013] Preferably, a pushing plate is fixedly installed on the rotating ring. The pushing plate is arranged in a V shape, and the opening of the pushing plate faces the blanking hole. Both ends of the pushing plate are slidably matched with the front and rear side walls inside the storage box.

[0014] The effect is that: when the pushing plate rotates, the auxiliary agent can be continuously pushed to the blanking hole, facilitating the downward feeding of the auxiliary agent.

[0015] Preferably, the moving groove is of an arc structure, and the elastic member is a spring. One end of the elastic member abuts against the driving rod.

[0016] Preferably, a filter screen is fixedly installed at a position close to the bottom of the telescopic pipe. A fixing column is fixedly installed on the filter screen. A fixing plate is fixedly installed on the outer side wall of the fixing column. A rotating seat is rotatably installed at the upper end of the fixing column. A clamping plate is fixedly installed on the rotating seat. Both the clamping plate and the fixing plate are arranged along the radial direction of the filter screen. A through hole is formed in the rotating seat, and a screw rod is fitted in the through hole. A magnet is fixedly installed at the upper end of the screw rod. A top plate is fixedly installed at a position close to the top of the telescopic pipe, and a square groove is formed on the lower end surface of the top plate.

[0017] The effect is that: during the storage of the auxiliary agent, the situation of moisture absorption and caking may occur. Once the caked material is added to the viscous material, it is very difficult to stir it open. Therefore, by utilizing the telescopic property of the telescopic pipe, the clamping plate continuously squeezes the auxiliary agent to avoid the caking of the auxiliary agent.

[0018] Preferably, a method for blending a modified resin uses the above-mentioned blending device for modified resin, and it includes the following steps:

[0019] Step 1, add the auxiliary agent into the storage box;

[0020] Step 2, inject the stock solution into the blending barrel, and the stirring shaft rotates to start stirring;

[0021] Step 3, during the rotation of the stirring shaft, the discharge seat can be driven to rotate synchronously through the driving rod connected to the stirring shaft. When the discharge seat rotates, it will reciprocate up and down along the stirring shaft. The blanking cylinder rotates continuously, and the auxiliary agent falls into the discharge seat through the telescopic pipe. As the blanking cylinder rotates, the auxiliary agent is continuously brought into the material for mixing;

[0022] Step 4: The viscosity of the material increases, and the rotational resistance of the discharge seat and the telescopic pipe in the material becomes larger. When the rotational resistance 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, it will synchronously drive the telescopic pipe and the blanking ball to rotate together, and the through-hole communicating between the top seat and the blanking ball becomes smaller, so as to reduce the speed of additive addition.

[0023] Step 5: After the resin is formulated, the resin is discharged.

[0024] The effect is as follows: The additive passes through the top seat, the blanking ball and the telescopic pipe and is discharged from the blanking cylinder into the material in the mixing barrel. While the stirring shaft rotates to stir the material, it can drive the discharge seat to rotate around the axis of the mixing barrel. The discharge seat synchronously drives the rotating ring, the top seat, the blanking ball and the telescopic pipe to rotate together. While rotating, the driving rod continuously moves along the driving groove, which can force the discharge seat to continuously rise and fall, so as to evenly scatter the additive to different heights of the material. As the additive is added, 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 pipe and the blanking ball will rotate together, and the elastic member is compressed, making the through-hole communicating between the top seat and the blanking ball smaller, reducing the speed of additive addition, and making the additive stir more fully in the viscous material.

[0025] Adopting the above technical solution, the beneficial effects of the present invention are as follows: The stirring shaft can drive the discharge seat to rotate around the axis of the mixing barrel, and at the same time the discharge seat can continuously rise and fall, so as to evenly scatter the additive to different heights of the material. When the viscosity of the material increases, 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 pipe and the blanking ball will rotate together, and the elastic member is compressed, making the through-hole communicating between the top seat and the blanking ball smaller, reducing the speed of additive addition, making the additive stir more fully in the viscous material, and at the same time, improving the stirring efficiency and shortening the stirring time.

Detailed implementation manners

[0038] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0039] As Figures 1 to 10 shown, a specific embodiment of a modified resin dispensing device and dispensing process of the present invention includes a dispensing barrel 10, a stirring shaft 11, a drive groove 14, a storage tank 20, a storage box 30, a swivel ring 31, a top seat 33, a blanking ball 34, a telescopic pipe 35, a discharge seat 40, a blanking cylinder 41, a moving groove 42, an elastic member 43 and a drive rod 44.

[0040] The stirring shaft 11 is rotatably installed in the dispensing barrel 10, and the drive groove 14 is wavy and is provided around the inner wall of the dispensing barrel 10.

[0041] The storage bin 20 and the material storage box 30 are installed above the dispensing barrel 10. The storage bin 20 can load a variety of additives, and the additives can be added into the material storage box 30. A rotating ring 31 is rotatably installed on the material storage box 30. The rotating ring 31 is in the shape of a boss. A material discharging hole is formed in the rotating ring 31. The width of the protruding part of the rotating ring 31 is slightly larger than the diameter of the material discharging hole, and the upper surface of the protruding part is flush with the inner bottom wall of the material storage box 30.

[0042] A top seat 33 is fixedly installed at the bottom of the rotating ring 31. A discharging ball 34 is rotatably installed on the top seat 33. Through holes are formed in both the top seat 33 and the discharging ball 34, and are communicated with the material discharging hole on the rotating ring 31. A telescopic pipe 35 is also communicated below the discharging ball 34.

[0043] The lower end of the telescopic pipe 35 is installed with a discharging seat 40. A discharging cylinder 41 is rotatably installed at the bottom of the discharging seat 40. After the additives pass through the telescopic pipe 35, they can enter the material in the dispensing barrel 10 from the discharging cylinder 41.

[0044] Moving grooves 42 are formed on both sides of the discharging seat 40. Driving rods 44 are slidably installed in the moving grooves 42. Elastic members 43 are also arranged in the moving grooves 42. One driving rod 44 on one side of the discharging seat 40 is slidably matched with the stirring shaft 11, and the other driving rod 44 extends into the driving groove 14, so that the stirring shaft 11 can drive the discharging seat 40 to rotate, and at the same time, the driving groove 14 can force the discharging seat 40 to continuously lift and lower, so that the additives can be evenly scattered at different heights of the material.

[0045] When the viscosity of the material increases, the rotational resistance of the discharging seat 40 becomes larger. The discharging seat 40, the telescopic pipe 35 and the discharging ball 34 will rotate together, and the elastic member 43 is compressed, so that the through hole communicated between the top seat 33 and the discharging ball 34 becomes smaller, reducing the speed of additive addition.

[0046] During operation, the storage bin 20 can sequentially add the additives into the material storage box 30. The additives pass through the top seat 33, the discharging ball 34 and the telescopic pipe 35 and are discharged from the discharging cylinder 41 into the material in the dispensing barrel 10. While the stirring shaft 11 rotates to stir the material, it can drive the discharging seat 40 to rotate around the axis of the dispensing barrel 10. The discharging seat 40 synchronously drives the rotating ring 31, the top seat 33, the discharging ball 34 and the telescopic pipe 35 to rotate synchronously. During rotation, the driving rod 44 continuously moves along the driving groove 14, which can force the discharging seat 40 to continuously lift and lower, so that the additives can be evenly scattered at different heights of the material. As the additives are added, the viscosity of the material begins to increase, and the rotational resistance of the discharging seat 40 becomes larger. When its rotational resistance is greater than the elastic force of the elastic member 43, the discharging seat 40, the telescopic pipe 35 and the discharging ball 34 will rotate together, and the elastic member 43 is compressed, so that the through hole communicated between the top seat 33 and the discharging ball 34 becomes smaller, reducing the speed of additive addition, so that the additives can be stirred more fully in the viscous material.

[0047] As Figure 1 and Figure 2 , a stirring shaft 11 is rotatably installed inside the dispensing barrel 10. The stirring shaft 11 is driven by a motor. A discharge valve 12 is installed at the bottom of the dispensing barrel 10. A liquid inlet pipe 13 is connected to a position near the upper part of the outer side wall of the dispensing barrel 10. The stock solution can be added into the dispensing barrel 10 through the liquid inlet pipe 13, or after the work is completed, water can be injected into the dispensing barrel 10 through the liquid inlet pipe 13 for cleaning.

[0048] A driving groove 14 is annularly arranged on the inner wall of the dispensing barrel 10. The driving groove 14 is wavy (as Figure 2 ), during the rotation of the discharge seat 40, it can be continuously lifted and lowered, and how to achieve the lifting will be described in detail later.

[0049] The storage tank 20 is fixedly installed on the side wall of the dispensing barrel 10. A plurality of partition plates 21 are arranged at intervals inside the storage tank 20. The partition plates 21 divide the inside of the storage tank 20 into a plurality of storage cavities, which can load different types of additives. A blanking valve 22 is arranged at the bottom of each storage cavity, and specific additives can be added according to needs. A blanking pipe 23 is connected to the lower part of the storage tank 20, and the additives in the storage cavity can be discharged through the blanking pipe 23.

[0050] As Figure 1 and Figure 7 , a storage box 30 is fixedly installed at the upper end of the dispensing barrel 10, and the blanking port of the blanking pipe 23 is directly opposite to the storage box 30, so that the additives in the storage tank 20 can be added into the storage box 30.

[0051] The storage box 30 is coaxially arranged with the dispensing barrel 10, and an annular groove penetrating up and down is opened at the bottom of the storage box 30. A rotating ring 31 is also slidably fitted at the bottom of the storage box 30. The rotating ring 31 is in a boss shape. The protruding part of the rotating ring 31 extends upward into the annular groove on the storage box 30, and the protruding part of the rotating ring 31 is slidably fitted with the annular groove. The upper surface of the protruding part is flush with the inner bottom wall of the storage box 30 (as Figure 3 ). A blanking hole penetrating up and down is opened on the protruding part of the rotating ring 31, and the width of the protruding part of the rotating ring 31 is slightly larger than the diameter of the blanking hole, ensuring that during the rotation of the rotating ring 31, the additives can be discharged from the blanking hole.

[0052] A pushing plate 32 is fixedly installed on the upper surface of the protruding part of the rotating ring 31 and near the blanking hole. The pushing plate 32 is arranged in a V shape, and the opening of the pushing plate 32 faces the blanking hole. The two ends of the pushing plate 32 are slidably fitted with the opposite side walls inside the storage box 30. When the rotating ring 31 and the pushing plate 32 rotate, the additives in the storage box 30 are in a static state relative to the rotating ring 31. Therefore, when the pushing plate 32 rotates, it can continuously gather the additives towards the middle so that the additives can be discharged from the blanking hole.

[0053] As Figure 2 、Figure 3 With Figure 5 , a top seat 33 is fixedly installed at the bottom of the swivel ring 31. The top seat 33 is communicated with the material discharge hole on the swivel ring 31. A material discharge ball 34 is rotatably installed inside the top seat 33. The material discharge ball 34 is of a spherical structure. Circular through holes are provided on both the top seat 33 and the material discharge ball 34, and the through holes of the two are communicated to ensure that the auxiliary agent can fall after passing through the through holes.

[0054] When the material discharge ball 34 rotates, the through holes between the two will be misaligned (as shown in Figure 10 ), and at this time, the area of the connection between the top seat 33 and the material discharge ball 34 will become smaller, which can reduce the amount of the auxiliary agent falling.

[0055] Such as Figure 5 , a telescopic tube 35 is connected below the material discharge ball 34. The telescopic tube 35 is composed of a plurality of telescopic units, and the plurality of telescopic units are hermetically and slidably connected to each other. In this embodiment, the telescopic units are all circular tubular structures.

[0056] Continuing back to Figure 5 With Figure 6 , the lowermost end of the telescopic tube 35 is fixedly installed with a discharge seat 40 communicated therewith. The discharge seat 40 is of a bottom-opening structure, and a discharge tube 41 is rotatably installed at the bottom. The lower half of the discharge tube 41 protrudes from the lower end surface of the discharge seat 40, and discharge grooves are provided on the outer side surface of the discharge tube 41. The discharge grooves are of an arc structure, and the axis of the discharge groove is parallel to the axis of the discharge tube 41. When the discharge tube 41 rotates, the auxiliary agent falling into the discharge seat 40 through the telescopic tube 35 will fall into the discharge groove above the discharge tube 41. As the discharge tube 41 rotates, when the discharge groove drives the auxiliary agent to rotate to the lower part, the auxiliary agent will enter the material for mixing.

[0057] Such as Figure 6 , a gear 45 is connected to the discharge tube 41, and a rack 46 meshing with the gear 45 is fixedly installed on the side surface of the stirring shaft 11. When the discharge seat 40 continuously rises and falls, the discharge tube 41 can be driven to rotate continuously through the gear 45.

[0058] Since the discharge tube 41 is located in the material, when it rotates, the discharge groove can send out the auxiliary agent. However, when the discharge groove rotates upward and returns to the discharge seat 40 again, the material will be brought into the discharge seat 40. To solve this problem, a scraping plate 51 is also installed on the discharge seat 40 to scrape the discharge groove, which will be described in detail below.

[0059] Such as Figure 9, an installation groove 50 is formed on a side wall of the discharge seat 40 that is consistent with the axial direction of the blanking cylinder 41, and the installation groove 50 is close to the bottom opening of the discharge seat 40. The opening of the installation groove 50 faces the blanking groove on the blanking cylinder 41. A scraping plate 51 is slidably installed in the installation groove 50, and a spring is arranged on the scraping plate 51. In the released state of the spring, the scraping plate 51 extends out of the installation groove 50. Therefore, when the blanking cylinder 41 rotates, the scraping plate 51 can continuously abut against the blanking groove in the blanking cylinder 41. As the arc of the blanking groove changes, the scraping plate 51 continuously reciprocates in the installation groove 50, and the scraping plate 51 can continuously scrape the blanking groove that returns to the discharge seat 40 after the additive is discharged, avoiding bringing materials into the discharge seat 40.

[0060] Continue to return to Figure 4 , Figure 5 and Figure 6 , arc-shaped moving grooves 42 are formed on both side surfaces of the discharge seat 40, driving rods 44 are arranged in the moving grooves 42, and elastic members 43 are also installed in the moving grooves 42. In this embodiment, the elastic member 43 is a spring. In the released state of the spring, one end abuts against the driving rod 44. One end of the driving rod 44 on one side away from the moving groove 42 is located in the driving groove 14, and a vertical sliding groove 47 is formed on the side surface of the stirring shaft 11. 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 and the driving groove 14 is wavy, when the discharge seat 40 rotates, it will be forced to continuously rise and fall along 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.

[0061] During the rotation of the discharge seat 40, it will drive the telescopic pipe 35, the top seat 33, the blanking ball 34 and the rotating ring 31 to rotate synchronously. When the discharge seat 40 rises and falls, it will drive the telescopic pipe 35 to extend or contract, so that after the additive is discharged, it is discharged from different heights in the material. With the stirring of the material, the additive can be fully mixed in the material.

[0062] Under normal conditions, when the stirring shaft 11 drives the discharge seat 40 to rotate, the viscosity of the material is not too high yet. However, with the addition of the additive, the viscosity of the material increases. Therefore, when the discharge seat 40 and the telescopic pipe 35 rotate in the material, the resistance will become larger. When the rotation resistance is greater than the elastic force of the elastic member 43, the elastic member 43 will be gradually compressed. The two driving rods 44 are respectively restricted by the driving groove 14 and the sliding groove 47, so the discharge seat 40 will rotate at a certain angle along the moving groove 42.

[0063] When the discharge seat 40 rotates, it will synchronously drive the telescopic pipe 35 and the blanking ball 34 to rotate together, and the through hole communicating between the top seat 33 and the blanking ball 34 becomes smaller (as shown in Figure 10 ), so that the speed of additive addition can be reduced. Because the viscosity of the material increases, when the speed of additive addition is too fast, it is very difficult for the additive to be fully stirred in the viscous material and it is easy to be distributed in lumps, increasing the stirring time. Therefore, according to the viscosity of the material, the speed of additive addition is adjusted in real time. When the material is viscous, the speed of additive addition is reduced, so that the additive can be stirred more quickly and fully in the viscous material, avoiding the situation of uneven stirring of the additive.

[0064] During the storage of the additive, the situation of moisture absorption and caking may occur. Once the caked material is added to the viscous material, it is very difficult to stir it. Therefore, in view of this problem, the present invention also adds a crushing component, specifically as follows:

[0065] As shown in Figure 8 , a filter screen 60 is fixedly installed in the lowermost section of the telescopic pipe 35. A fixing column 61 with a hollow structure is fixedly installed at the center position of the filter screen 60. A fixing plate 62 is fixedly installed on the outer side wall of the fixing column 61. The fixing plate 62 is arranged along the radial direction of the filter screen 60. A rotating seat 63 is rotatably installed at the upper end of the fixing column 61. A clamping plate 64 is fixedly installed on the rotating seat 63. The lower end faces of the fixing plate 62 and the clamping plate 64 are both slidably matched with the filter screen 60.

[0066] A through hole is formed in the rotating seat 63, and a screw rod 65 is fitted in the through hole. A square magnet 66 is fixedly installed at the upper end of the screw rod 65. A top plate 67 is fixedly installed inside the uppermost section of the telescopic pipe 35. The top plate 67 is made of iron, and a square groove is formed on the lower end face of the top plate 67.

[0067] When the telescopic pipe 35 contracts, the screw rod 65 moves upward until it abuts against the top plate 67. At this time, the magnet 66 is located in the square groove on the lower end face of the top plate 67, which can prevent the screw rod 65 from rotating and adsorb on the top plate 67. As the telescopic pipe 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 towards the fixing plate 62 until the screw rod 65 is completely inserted into the rotating seat 63 and the inner side of the fixing column 61, and the clamping plate 64 rotates to the maximum stroke and just abuts against the fixing plate 62 at this time, so as to squeeze the additive on the fixing plate 62 and crush the additive.

[0068] It should be particularly emphasized that filter holes are provided on both the clamping plate 64 and the fixing plate 62. When squeezing the additive, it can make the additive pass through the filter holes, ensuring the squeezing effect.

[0069] When the telescopic tube 35 extends, since the magnet 66 is adsorbed on the top plate 67, the filter screen 60 will first drive the rotating base 63 to move downward, and the screw rod 65 remains stationary. When the rotating base 63 moves downward, the screw rod 65 will force the clamping plate 64 to rotate in the reverse direction until the clamping plate 64 rotates to the other side of the fixing plate 62 and squeezes the material again. As the rotating base 63 descends to the maximum stroke of the screw rod 65, when the telescopic tube 35 continues to extend, the magnet 66 will be separated from the top plate 67.

[0070] This reciprocating cycle causes the clamping plate 64 to continuously rotate back and forth, squeezing the auxiliary agent onto the fixing plate 62 and crushing the nodules that appear in the auxiliary agent.

[0071] A blending device for a modified resin according to an embodiment of the present invention, the blending process of which includes the following steps:

[0072] Step 1, Add a variety of auxiliary agents into the storage tank 20. According to needs, different blanking valves 22 can be opened to add different auxiliary agents into the storage box 30.

[0073] Step 2, Inject the stock solution into the blending barrel 10, and the stirring shaft 11 starts to rotate for stirring.

[0074] In the process of the stirring shaft 11 rotating, the discharge seat 40 can be driven to rotate synchronously through the driving rod 44 connected to the stirring shaft 11. 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 along with the driving groove 14. The sliding 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 rising and falling process of the discharge seat 40, the blanking cylinder 41 can be driven to continuously rotate through the gear 45. The blanking groove of the blanking cylinder 41 can send out the auxiliary agent, and the auxiliary agent that falls into the discharge seat 40 through the telescopic tube 35 will fall into the blanking groove. As the blanking cylinder 41 rotates, when the blanking groove drives the auxiliary agent to rotate to the lower part, the auxiliary agent will enter the material for mixing.

[0075] Step 4, As the viscosity of the material increases, when the discharge seat 40 and the telescopic tube 35 rotate in the material, the resistance will become larger. When the resistance of its 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 at a certain angle along the moving groove 42. When the discharge seat 40 rotates, it will synchronously drive the telescopic tube 35 and the blanking ball 34 to rotate together, and the through hole communicating between the top seat 33 and the blanking ball 34 becomes smaller, so as to be able to reduce the speed of adding the auxiliary agent.

[0076] Step 5, After the resin blending is completed, open the discharge valve 12 to discharge the resin.

[0077] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
