[0002] Biodegradable masterbatch is a new type of special colorant for polymer materials, also known as pigment preparation. Masterbatch is mainly used in plastics. It is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate made by uniformly loading an excessive amount of pigment into the resin, and can be called pigment concentrate. In the production process of masterbatch, a twin-screw extruder is used. After the finished masterbatch is extruded, it is often difficult to efficiently shear the extruded masterbatch. It often requires external equipment for independent shearing. Shearing and drying are often separated into multiple different processing stages, which makes it difficult to coordinate and integrate production. This needs to be improved.

[0048] In summary, the beneficial effects of the above-described technical solutions conceived by this invention compared with the prior art include:

[0049] 1. The biodegradable masterbatch twin-screw extrusion equipment and extrusion method of the present invention, through the arrangement of linkage shearing components, can drive linkage wheel two to rotate when linkage wheel one rotates. The first beneficial effect is that the drive plate moves downward and the two sets of inclined grooves on the drive plate drive the cutters to move closer together to quickly complete the shearing operation of the finished masterbatch, enabling synchronous and rapid shearing during the extrusion process. The second beneficial effect is that it can drive the connecting gear to rotate, and when the upright rod touches the guide rod, it can drive the displacement plate to move at one end. When the upright rod touches a set of sub-rods of the bidirectional lever, it can... The displacement plate is driven to move at the other end, which can drive the shearing plate to move the finished material in a timely manner to prevent the material from accumulating on one side during shearing. This results in a high degree of uniformity in material distribution. Thirdly, during the material distribution process, the air pump's drying operation can be further promoted. The material distribution is made more uniform during the distribution process, which increases the contact area between the finished material and the air pump's drying process, thus improving the drying efficiency of the finished material. Fourthly, when the ball head is about to switch from the straight groove to the arc groove, it can drive the energy storage switching component through the slope groove to perform a continuous and progressive switching operation.

[0050] 2. The biodegradable masterbatch twin-screw extrusion equipment and extrusion method of the present invention, through the arrangement of energy storage switching components, initially the triangular groove of the switching core plate can be inserted into the air duct and a ventilation gap is reserved. As the switching core plate gradually moves to the right, the ventilation gap between the triangular groove and the air duct can be progressively increased. On the one hand, progressive air drying can be carried out when shearing the finished material. As the tear between the cutter and the finished material gradually increases, the ventilation volume can be progressively increased to quickly carry out air drying at the tear. On the other hand, after the finished material falls into the collection box, it can continue to carry out progressive air drying. Furthermore, through the precise cooperation between the linkage shearing component and the energy storage switching component, the integrated and synchronous operation of shearing, turning and air drying can be simplified, simplifying the operation steps and improving the quality of the finished product.

[0051] 3. The biodegradable masterbatch twin-screw extrusion equipment and extrusion method of the present invention, the combined benefit effect of the linkage shearing component and the energy storage switching component, can accelerate the overall extrusion efficiency of the extrusion component by increasing the speed of the drive motor, and can simultaneously increase the speed of the roller to quickly make the drive plate reciprocate, so as to control the cutting efficiency of the cutter through the inclined groove, and accelerate and simplify the material feeding effect of the linkage shearing component. Secondly, it can quickly improve the drying effect of the finished material through the energy storage switching component, and after the material feeding speed of the linkage shearing component is increased, it can further dry the material with the energy storage switching component and the air pump.

[0074] 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.

[0075] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0076] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0077] In the embodiments, by Figure 1-14Provided is a biodegradable masterbatch twin-screw extruder, comprising: an operating table 1 with a mounting plane and a collection box 11 on the operating table 1; an extrusion component 2 disposed on the mounting plane; a power component 3 disposed on the operating table 1 for driving the extrusion component 2 to perform extrusion operations; and a linkage shearing component 4, comprising a trigger section, a shearing section cooperating with the trigger section, and a toggle section cooperating with the trigger section, wherein when the power component 3 outputs power, it can drive the trigger section to move, and the trigger section can switch between a first movement position and a second movement position. When transitioning from the first moving position to the second moving position, the shearing section can be driven to shear the extruded material flowing out from the extrusion member 2; the actuating plate 5 is arranged on both sides of the actuating section, and each set of actuating plates 5 has multiple sets of internal pins 51; the air pump 7 is located on the linkage shearing member 4, and the air pump 7 has a hose 71, and an air duct 72 is located at one end of the hose 71; and the energy storage switching member 6 is detachably arranged on the linkage shearing member 4. The energy storage switching member 6 can be triggered when the triggering section has a downward movement tendency, and when the energy storage switching member 6 is triggered, the air pump 7 can be adjusted.

[0078] The overall concept of this invention is that, through the arrangement of the linkage shearing component 4, when the linkage wheel 35 rotates, it can drive the linkage wheel 493 to rotate, thereby driving the column wheel 42 to rotate. After the column wheel 42 rotates, it can change the movement trajectory of the ball head 45 through the straight groove and the arc groove. During the transition from the straight groove to the arc groove, it can drive the trigger plate 43 to move downward as a whole. When the trigger plate 43 moves downward, the first beneficial effect is that the drive plate 46 moves downward and the two sets of inclined grooves on the drive plate 46 drive the cutter 48 to move closer to each other to quickly complete the shearing operation of the color masterbatch product. It can realize rapid shearing that is synchronized during the extrusion operation. The second aspect is... The beneficial effects include: driving the connecting gear 492 to rotate; when the upright rod 494 touches the guide rod 495, driving the displacement plate 496 to move at one end; and when the upright rod 494 touches a set of sub-rods of the bidirectional lever 499, driving the displacement plate 496 to move at the other end. This allows the lever 5 to promptly move the sheared finished material, preventing material accumulation on one side during shearing and ensuring high uniformity of material distribution. Thirdly, the material distribution process further promotes the drying operation of the air pump 7, resulting in more uniform material distribution and increasing the contact area between the finished material and the air pump 7 for drying, thus improving the drying efficiency. The drying efficiency of the material; the fourth aspect of the effect is that when the ball head 45 is about to switch from the straight groove to the arc groove, it can drive the energy storage switching component 6 through the slope groove 49 to carry out a continuous progressive switching operation. Through the deployed energy storage switching component 6, in the initial state, the slope groove 49 and the follower plate 62 are in contact. As the slope groove 49 moves, it can push the follower plate 62 to the left. The leftward movement of the follower plate 62 and the stop block 65 can cause the balance plate 66 to tilt to the side. After the balance plate 66 tilts to the side, it can press the switching core plate 691 to move to the right as a whole. Initially, the triangular groove 692 of the switching core plate 691 can pass through the air duct 72 and leave a ventilation gap. As the switching core plate 691 gradually moves to the right... During the process, the ventilation gap between the triangular groove 692 and the air duct 72 can be progressively increased. On the one hand, progressive air drying can be carried out when shearing the finished material. As the tear between the cutter 48 and the finished material gradually increases, the ventilation volume can be progressively increased to quickly dry the tear. On the other hand, after the finished material falls into the collection box 11, it can continue to be progressively dried. Furthermore, through the precise cooperation between the linkage shearing component 4 and the energy storage switching component 6, the integrated synchronous operation of shearing, turning, and air drying can be simplified, simplifying the operation steps and improving the quality of the finished product.

[0079] Next, a more specific structure and construction of the extrusion component 2 will be given for further explanation. The extrusion component 2 includes: a frame 21, which is detachably arranged on the mounting plane; an extrusion frame 22, which is arranged inside the frame 21, and has a hopper 23 on the extrusion frame 22. A right extrusion rod 24 and a left extrusion rod 25 are rotatably arranged inside the extrusion frame 22, and both the left extrusion rod 25 and the right extrusion rod 24 can pass through the frame 21; and an extension shaft 26, which is connected to one end of the right extrusion rod 24.

[0080] Next, the overall working principle and effect of the extrusion component 2 will be further explained. The masterbatch material to be extruded is injected into the extrusion frame 22 through the hopper 23. By turning on the power component 3, the right extrusion rod 24 and the left extrusion rod 25 can be driven to rotate. During the rotation of the right extrusion rod 24 and the left extrusion rod 25, heating is carried out simultaneously to complete the extrusion of the masterbatch raw material, which flows out through the tail end of the extrusion frame 22.

[0081] It should also be noted that the extrusion component 2 is a known component in the prior art, and therefore will not be described in detail in this invention.

[0082] Next, a more specific structure and construction of the power component 3 will be given for further explanation. The power component 3 includes a drive motor 31, which is detachably mounted on the operating table 1; a bevel gear 32, which is detachably mounted on the output end of the drive motor 31; and a rack 33, which is rotatably mounted on the operating table 1. A bevel gear 34 that can mesh with the bevel gear 32 is detachably mounted on the rack 33. A linkage wheel 35 is detachably mounted on the top of the rack 33. The output end of the bevel gear 32 controls the rotation of the extension shaft 26 through a belt and pulley.

[0083] Next, the working principle and effect of the power component 3 will be further explained. By turning on the drive motor 31, the belt can be driven to rotate, which in turn drives the pulley to rotate, thereby controlling the extension shaft 26 to rotate, and thus controlling the right extrusion rod 24 and the left extrusion rod 25 to rotate synchronously. The right extrusion rod 24 and the left extrusion rod 25 also move synchronously through the transmission between the belt and the pulley. At the same time, the bevel gear 1 32 and bevel gear 2 34 can be driven to rotate, thereby driving the rack 33 and the linkage wheel 1 35 to rotate, and thus synchronously driving the linkage shearing component 4 to perform synchronous shearing operations during the extrusion process.

[0084] Next, a more specific structure and construction of the linkage shearing component 4 will be given for further explanation. The linkage shearing component 4 has a trigger section including: a base plate 41, which is detachably mounted on the operating table 1; a column wheel 42, which is rotatably arranged on the base plate 41, and has two sets of straight grooves and two sets of arc grooves overlapping the two sets of straight grooves on the outer circumferential surface of the column wheel 42; a trigger plate 43, which can slide longitudinally along the base plate 41, and has a slope groove 49 on the trigger plate 43; a drive rod 44 is detachably arranged on the trigger plate 43, and has a ball head 45 that can slide along the straight groove or the arc groove on the drive rod 44; the linkage shearing component 4 has a shearing section including: a slide rail, which is detachably arranged on the base plate 41; a drive plate 46, which is detachably arranged on the trigger plate 43, and has two sets of inclined grooves on the drive plate 46; and a blade plate 47, which is slidably arranged on the slide rail. A needle roller is detachably mounted on the blade plate 47, and a cutting blade 48 is detachably mounted on the blade plate 47. In the initial state, the needle roller is in contact with the lowest point of the inclined groove. The linkage shearing member 4 has a toggle section including: a connecting rod 491, which is rotatably mounted on the base plate 41 and connected to the column wheel 42. A second linkage wheel 493 is mounted on the connecting rod 491, and the second linkage wheel 493 is connected to the first linkage wheel 3 via a belt. The system includes a 5-phase connection; a connecting gear 492, which is detachably mounted on a connecting rod 491, and two sets of uprights 494 on the connecting gear 492; two sets of pulleys 498, with an interlocking gap between each set of pulleys 498, a displacement plate 496 within the interlocking gap, a guide rod 495 on the displacement plate 496, and an embedded rod 497 on the displacement plate 496; and a bidirectional lever 499, which is rotatably mounted on a base plate 41.

[0085] Next, the working principle and effect of the linkage shearing component 4 will be further explained. When the linkage wheel 1 35 rotates, it can drive the linkage wheel 2 493 to rotate, which in turn drives the column wheel 42 to rotate. After the column wheel 42 rotates, it can change the movement trajectory of the ball head 45 through the straight groove and the arc groove. During the transition from the straight groove to the arc groove, it can drive the trigger plate 43 to move down as a whole. When the trigger plate 43 moves down, the first beneficial effect is that the drive plate 46 moves down and the two sets of inclined grooves on the drive plate 46 drive the cutter 48 to move closer to each other to quickly complete the shearing operation of the color masterbatch product. It can realize the synchronous follow-up rapid shearing during the extrusion operation. The second beneficial effect is that it can drive the connecting gear 492 to rotate. When the upright 494 touches the guide rod 49 When the 5th phase is in operation, the displacement plate 496 can be driven to move at one end. When the upright 494 touches a set of sub-rods of the bidirectional lever 499, the displacement plate 496 can be driven to move at the other end, so as to drive the lever 5 to move the sheared finished material in a timely manner, so as to prevent the material from accumulating on one side during the shearing of the finished product. The material can be spread evenly. Thirdly, during the material spreading process, the air pump 7 can be further promoted to dry the material. During the material spreading process, the material can be spread evenly, and the contact surface between the finished material and the air pump 7 can be increased, thus improving the drying efficiency of the finished material. Fourthly, when the ball head 45 is about to switch from the straight groove to the arc groove, it can drive the energy storage switching component 6 through the slope groove 49 to perform a continuous progressive switching operation.

[0086] In some embodiments, more specifically, the ball head 45 slides in the straight groove in the initial position, forms a first movement position when the ball head 45 is in the straight groove, and forms a second movement position when the ball head 45 is in the arc groove.

[0087] In some embodiments, more specifically, in the initial position, the guide rod 495 is located on one side of one set of uprights 494, and when the uprights 494 touch the guide rod 495, the displacement plate 496 has a tendency to move to one side.

[0088] In some embodiments, in order to further prevent the displacement plate 496 from jamming during movement and to simultaneously improve the amplitude change of the bidirectional lever 499 during swing, the bidirectional lever 499 has two sets of sub-levers. One set of sub-levers has a socket that allows the embedded lever 497 to pass through. The other set of sub-levers is located on the other side of the upright lever 494. The two sets of sub-levers are at an acute angle.

[0089] Next, a more specific structure and construction of the energy storage switching component 6 will be given for further explanation. The energy storage switching component 6 includes: a switching plate 61, which is detachably arranged on the linkage shearing component 4; a follower plate 62 slidably disposed within the switching plate 61; a slope at the bottom of the follower plate 62; a limiting rod 63 at one end of the follower plate 62, which can pass through the switching plate 61; and a spring 64 on the limiting rod 63; and a stop block 65 located on the follower plate 61. 2. The middle part; balance plate 66, which is rotatably arranged on switching plate 61. In the initial position, one end of balance plate 66 overlaps with stop block 65; limit plate 67, which is arranged on switching plate 61. A limit rod 68 is slidably inserted on limit plate 67. A spring 69 is sleeved on limit rod 68. A switching core plate 691 is on spring 69. A triangular groove 692 is inside the switching core plate 691. In the initial position, the switching core plate 691 overlaps with the other end of balance plate 66.

[0090] Next, the overall operating principle and effect of the energy storage switching component 6 will be further explained. In the initial state, the slope groove 49 and the follower plate 62 are in contact. As the slope groove 49 moves, it can push the follower plate 62 to the left. The leftward movement of the follower plate 62 and the stop block 65 can cause the balance plate 66 to tip over. After the balance plate 66 tip over, it can press the switching core plate 691 to move to the right. Initially, the triangular groove 692 of the switching core plate 691 can pass through the air duct 72 and leave a ventilation gap. As the switching core plate 691 gradually moves to the right, the ventilation gap between the triangular groove 692 and the air duct 72 can be gradually increased. The progressive increase in air volume has several advantages. First, it enables progressive air drying during the shearing of finished materials. As the tear between the cutter 48 and the finished material gradually increases, the air volume is increased progressively to quickly dry the tear. Second, after the finished material falls into the collection box 11, it can continue to be dried progressively. Third, the precise coordination between the linkage shearing component 4 and the energy storage switching component 6 simplifies the integrated shearing, shearing, and air drying process, thus simplifying the operation and improving the quality of the finished product.

[0091] Finally, the combined benefits of the linkage shearing component 4 and the energy storage switching component 6 can accelerate the overall extrusion efficiency of the extrusion component 2 by increasing the speed of the drive motor 31. While increasing the speed of the drive motor 31, it can also simultaneously increase the speed of the roller 42, which can quickly make the drive plate 46 reciprocate to control the shearing efficiency of the cutter 48 through the inclined groove, and accelerate and simplify the material feeding effect of the linkage shearing component 4. Secondly, it can quickly improve the drying effect of the finished material through the energy storage switching component 6. After the material feeding speed of the linkage shearing component 4 is increased, it can further dry the material together with the energy storage switching component 6 and the air pump 7.

[0092] Another technical problem to be solved by this invention is an extrusion method for a biodegradable masterbatch twin-screw extrusion device.

[0093] S1. Feeding and extrusion of color masterbatch: The color masterbatch raw material is injected into the extrusion component 2, and the extrusion of the color masterbatch raw material is completed by turning on the power component 3.

[0094] S2, Shearing operation of masterbatch: When the power component 3 outputs, it can drive the trigger section to move. The trigger section can switch between the first movement position and the second movement position. When the trigger section changes from the first movement position to the second movement position, it can drive the shearing section to shear the extruded material flowing out from the extrusion component 2.

[0095] S3. Material feeding operation during the linkage shearing process: When the trigger section of the linkage shearing component 4 moves, it can drive the feeding section to feed the finished product after shearing, so as to collect the finished product.

[0096] S4. Drying operation during the shearing process: By turning on the air pump 7, the masterbatch extruded material can be dried by blowing air.

[0097] S5. Energy storage switching operation during the drying process: When the trigger segment of the linkage shearing component 4 changes from the first movement position to the second movement position, the drying degree of the air pump 7 can be continuously and gradually switched accordingly.

[0098] In summary, the interconnected shearing component 4, when the first interconnected wheel 35 rotates, can drive the second interconnected wheel 493 to rotate, thereby driving the column wheel 42 to rotate. After the column wheel 42 rotates, it can change the movement trajectory of the ball head 45 through the straight groove and the arc groove. During the transition from the straight groove to the arc groove, it can drive the trigger plate 43 to move downward as a whole. When the trigger plate 43 moves downward, the first beneficial effect is that the drive plate 46 moves downward and the two sets of inclined grooves on the drive plate 46 drive the cutter 48 to move closer to each other to quickly complete the shearing operation of the color masterbatch product. It can realize rapid shearing that is synchronized during the extrusion operation. The second beneficial effect is that it can drive... When the connecting gear 492 rotates, it can drive the displacement plate 496 to move at one end when the upright rod 494 touches the guide rod 495, and drive the displacement plate 496 to move at the other end when the upright rod 494 touches a set of sub-rods of the bidirectional lever 499. This can drive the lever 5 to move the sheared finished material in a timely manner, preventing material from accumulating on one side during shearing. This ensures a high degree of uniformity in material distribution. Thirdly, during the material distribution process, it can further promote the drying operation of the air pump 7. The material distribution is more uniform during the distribution process, increasing the contact area between the finished material and the air pump 7 for drying, thus improving the drying efficiency of the finished material. The fourth aspect of the effect is that when the ball head 45 is about to switch from a straight groove to an arc groove, it can drive the energy storage switching component 6 through the slope groove 49 to perform a continuous progressive switching operation. Through the deployed energy storage switching component 6, in the initial state, the slope groove 49 and the follower plate 62 are in contact. As the slope groove 49 moves, it can push the follower plate 62 to the left. The leftward movement of the follower plate 62 and the stop block 65 can cause the balance plate 66 to tilt to the side. When the balance plate 66 tilts to the side, it can press the switching core plate 691 to move to the right as a whole. Initially, the triangular groove 692 of the switching core plate 691 can pass through the air duct 72 and reserve a ventilation gap. As the switching core plate 691 gradually moves to the right... The ventilation gap between the triangular groove 692 and the air duct 72 can be progressively increased. On the one hand, it can perform progressive air drying when shearing the finished material. As the tear between the cutter 48 and the finished material gradually increases, the ventilation volume can be progressively increased to quickly dry the tear. On the other hand, after the finished material falls into the collection box 11, it can continue to perform progressive air drying. Furthermore, through the precise cooperation between the linkage shearing component 4 and the energy storage switching component 6, the integrated synchronous operation of shearing, turning, and air drying can be simplified, simplifying the operation steps and improving the quality of the finished product.
