[0001] The invention relates to the technical field of material conveying, and in particular to a plastic granule finished product conveyor with a screening function and a use method thereof. Background Art

[0002] In the process of producing plastic pellets, long-term pelletizing operation will cause wear of the cutter and mold, resulting in inconsistent shapes and sizes of the plastic pellets.

[0013] A finished plastic granule conveyor with screening function comprises the following steps:

[0014] Step 1: Before use, place the feed port into the finished plastic granule container, place the packaging barrel under the discharge pipe, and connect the discharge pipe to the waste barrel;

[0020] By allowing the plastic particles that fall into the first collecting cavity to fall from the through hole into the second collecting cavity and then be discharged from the discharge pipe on the left, it is avoided that the conveying hose is bent and squeezed to squeeze the plastic particles, so that the plastic particles that do not meet the specifications are squeezed into the screening net again;

When the present invention is tilted, the plastic particles piled together along the inclined surface are separated in each small cavity. At the same time, with the help of hot air introduced by the drying hose, the plastic particles in each small cavity are quickly blown to the through hole, thereby assisting the rapid screening and discharge of the plastic particles.

[0034] It also includes an extrusion rod 4, a connecting rod 102, an electric slip ring 103, a telescopic rod 104 and a first collecting tube 105; a screening net 1002 is arranged in the middle of the conveying hose 1; a plurality of telescopic rods 104 are fixedly connected to the shaftless spiral auger 2; an extrusion rod 4 is fixedly connected to the telescopic end of the telescopic rod 104; the extrusion rod 4 is provided with a plurality of extrusion parts, and the extrusion parts are expanded toward the discharge bin 3; the extrusion parts are connected by spring rods, and an elastic film is arranged on the outside of the spring rods; each extrusion part is composed of an extrusion cylinder 4 001 and a plurality of extrusion membranes 4002 are combined, a plurality of extrusion sheets are arranged on the extrusion cylinder 4001, the extrusion sheets and the extrusion membranes 4002 are staggered and fixedly connected to each extrusion sheet; a connecting rod 102 is fixedly connected to each extrusion sheet; an electric slip ring 103 is slidably connected to all the connecting rods 102; a first collecting tube 105 is arranged on the outside of the screening net 1002; the first collecting tube 105 and the screening net 1002 jointly form a first collecting cavity 10501.

[0035] It also includes a second collecting pipe 106 and a discharge pipe 107; the second collecting pipe 106 is fixedly connected to the conveying hose 1; the second collecting pipe 106 covers the screening net 1002 area; the second collecting pipe 106 is connected to two discharge pipes 107; the second collecting pipe 106 is located outside the first collecting pipe 105, and the second collecting pipe 106 and the first collecting pipe 105 together form a second collecting cavity 10601; the first collecting pipe 105 is provided with a plurality of through holes 10502.

[0036] It also includes a drying hose 108 ; the drying hose 108 is fixedly connected to the first collecting tube 105 , and a branch pipe on the drying hose 108 passes through the first collecting tube 105 and the second collecting tube 106 .

[0037] Each branch pipe of the drying hose 108 is arranged to be inclined toward the discharge bin 3 .

[0038] A metal spiral wire is arranged inside the drying hose 108 to prevent the drying hose 108 from collapsing or deforming during use, thereby facilitating stable transportation of hot air.

[0039] The screening net 1002 is made of corrosion-resistant material, which is beneficial to increasing the service life of the screening net 1002.

[0040] The inner walls of the first collecting tube 105 and the second collecting tube 106 are coated with polytetrafluoroethylene to prevent plastic particles from adhering to the inner walls of the first collecting tube 105 and the second collecting tube 106 .

[0041] The present invention aims at the existing conveyor that needs to add an additional process of screening plastic particles before conveying plastic particles, or the conveyor that needs to add an additional process of screening plastic particles after conveying plastic particles. The present invention is provided with an extrusion rod 4, a screening net 1002 and a first collecting tube 105; before use, the feed inlet 1001 is placed in the plastic particle finished product holding container, and the packaging barrel is placed under the discharge tube 101. It should be noted that the plastic particle finished product holding container stores all the plastic particle finished products that need to be packaged. The capacity of the plastic particle finished product holding container is much larger than the packaging barrel. When in use, the rotation is controlled The motor rotates clockwise from the discharge bin 3 to the inlet 1001, driving the shaftless spiral auger 2 fixed thereto to rotate. To ensure the screening effect during the conveying process, the shaftless spiral auger 2 rotates at a uniform low speed. The finished plastic granules in the plastic granule container enter the conveying hose 1 from the inlet 1001 and are driven by the shaftless spiral auger 2 to move toward the discharge bin 3. During the movement of the finished plastic granules toward the discharge bin 3, the electric slip ring 103 is driven to move from left to right. During the movement of the electric slip ring 103 to the right, a plurality of connecting rods 1 that are flared to the right are 02 is retracted, thereby driving the extrusion cylinder 4001 to be retracted, so that the extrusion rod 4 is reduced, and the electric slip ring 103 moves from right to left again. During the movement, the connecting rod 102 retracted by the electric slip ring 103 is restored to its original state, thereby driving the extrusion cylinder 4001 to be restored to its original state, so that the extrusion rod 4 squeezes the internal space of the conveying hose 1. Through the repeated sliding action of the electric slip ring 103, the connecting rod 102 makes the extrusion rod 4 repeatedly shrink and restore its original state, and continuously squeezes the finished plastic particles located on the outside of the extrusion rod 4, thereby ensuring that the finished plastic particles are in the process of being conveyed. Screening effect: when the finished plastic particles pass through the screening net 1002, the plastic particles smaller than the specified size in the finished plastic particles leak out from the screening net 1002 and enter the first collecting cavity 10501, thereby realizing screening of plastic particles that do not meet the specifications during the transportation of the finished plastic particles. There is no need to add additional screening steps before and after the plastic particles are transported, which is beneficial to reducing production costs. After the finished plastic particles are transported by the present invention, the plastic particles that do not meet the specifications are screened out, and the plastic particles that meet the specifications are transported to the discharge bin 3 and fall into the packaging barrel from the discharge pipe 101.

[0042] Furthermore, during the conveying of the finished plastic particles, as the finished plastic particles are conveyed from the feed port 1001 to the discharge bin 3, the plastic particles that do not meet the specifications will first leak out from the screening net 1002 area close to the feed port 1001, causing this part of the finished plastic particles to be continuously reduced during the conveying process to the discharge bin 3, resulting in the space of the screening net 1002 close to the discharge bin 3 being difficult to be filled with the finished plastic particles, affecting the conveying efficiency of the shaftless spiral auger 2. Therefore, when the electric slip ring 103 moves from the right side to the left side of the connecting rod 102, the extrusion rod 4 returns to its original shape and expands to the right, filling the space of the screening net 1002 close to the discharge bin 3, which is beneficial to ensuring the conveying efficiency of the shaftless spiral auger 2. In this way, while the extrusion rod 4 assists in screening the plastic particles, the extrusion rod 4 can also help ensure the conveying efficiency of the shaftless spiral auger 2.

[0043] Furthermore, the number of non-compliant plastic particles in each batch of finished plastic particles that enter the conveying hose 1 for screening and conveying is inconsistent. There are cases where the finished plastic particles are screened on the left side of the screening net 1002 during conveying and then continue to be conveyed to the right side of the screening net 1002. In this case, when the extrusion rod 4 returns to its original state, the space on the right side of the screening net 1002 will be compressed by the extrusion rod 4, affecting the conveying efficiency of the shaftless spiral auger 2. In this regard, when the electric slip ring 103 moves from left to right, the electric slip ring 103 causes several right-flashing connecting rods 102 to be retracted, thereby driving the extrusion cylinder 4001 to be retracted, causing the extrusion rod 4 to shrink. Thereby, while the extrusion rod 4 assists in screening the plastic particles and helps to ensure the conveying efficiency of the shaftless spiral auger 2, it effectively avoids affecting the conveying efficiency when there are no non-compliant plastic particles or only a small amount of non-compliant plastic particles.

[0044] Furthermore, since the plastic particles are immersed in water for cooling in the pre-process, they are usually dried before or after pelletizing, and then the dried plastic particles are transported and packaged. However, in the process of drying the plastic particles, there are a large number of plastic particles and they are piled up on each other, which may cause water vapor on the surface of some plastic particles. At this time, before transporting the finished plastic particles, the drying hose 108 is connected to an external conduit to pass hot air. The hot air passes through the drying hose 108 into the first collecting cavity 10501, and then the hot air passes through the screening net 1002 to dry the finished plastic particles, which is beneficial to improve the dryness of the plastic particles.

[0045] Furthermore, the conveying hose 1 is a hose. In the process of conveying finished plastic particles, when the feed port 1001 is low and the discharge bin 3 is high, that is, when the plastic particles need to be conveyed to a high place, the conveying hose 1 is bent and deformed, resulting in the plastic particles previously dropped into the first collecting cavity 10501 being squeezed due to the bending of the conveying hose 1, and the plastic particles that do not meet the specifications are squeezed into the screening net 1002 again. Therefore, a second collecting tube 106 is provided, and a second collecting cavity 10601 is formed between the second collecting tube 106 and the first collecting tube 105, and the plastic particles previously dropped into the first collecting cavity 10501 are squeezed into the screening net 1002 again. 1, and the plastic particles that subsequently enter the first collecting cavity 10501, will slide along the inclined inner wall of the first collecting tube 105 toward the feed port 1001 due to the influence of gravity, and fall from the through hole 10502, and further fall into the second collecting cavity 10601. The plastic particles that previously fell into the first collecting cavity 10501 are avoided through the first collecting tube 105. Since the conveying hose 1 is bent and squeezed to squeeze the plastic particles in the first collecting cavity 10501, the plastic particles that do not meet the specifications are squeezed into the screening net 1002 again, and then discharged from the discharge pipe 107 on the left.

[0046] Furthermore, if in the process of conveying the finished plastic particles, when the feed port 1001 is high and the discharge bin 3 is low, that is, the plastic particles need to be conveyed to a lower place, the plastic particles that do not meet the specifications after the previous screening and subsequent screening enter the first collecting cavity 10501, and are affected by gravity, slide along the inclined inner wall of the first collecting tube 105 toward the discharge bin 3, and fall from the through hole 10502, enter the second collecting cavity 10601, and are then discharged from the discharge pipe 107 on the right.

[0047] If the feed port 1001 of the conveying hose 1 is at the same height as the discharge bin 3, the non-standard plastic particles will easily accumulate in the first collecting cavity 10501 after entering the first collecting cavity 10501, and will be difficult to fall out of the through hole 10502. At this time, the non-standard plastic particles entering the first collecting cavity 10501 are blown by the hot air introduced by the drying hose 108. Since the branch pipe of the drying hose 108 is inclined toward the discharge bin 3, the introduced hot air will blow the non-standard plastic particles toward the discharge bin 3, so that the non-standard plastic particles can quickly fall out of the through hole 10502, enter the second collecting cavity 10601, and be discharged from the discharge pipe 107.

[0048] Embodiment 2: Based on embodiment 1, Figure 3 , Figure 4 and Fig. 9 As shown, a separator ring 201 is also included; a plurality of separator rings 201 are fixedly connected to the first collecting pipe 105 , and the inner annular surface of the separator ring 201 is in contact with the outer surface of the conveying hose 1 and the screening net 1002 .

[0049] It also includes a first interception net 202 and a second interception net 203; the first interception net 202 is rotatably connected to the conveying hose 1; the first interception net 202 is fixedly connected to the shaftless spiral auger 2; the first interception net 202 is provided with a fixing part, and the second interception net 203 is connected to the fixing part of the first interception net 202 via an electric rotating shaft.

[0050] A method for using a finished plastic particle conveyor with a screening function comprises the following steps:

[0051] Step 1: Before use, place the feed port 1001 into the plastic granule finished product container, place a packaging barrel under the discharge pipe 101, and connect the discharge pipe 107 to the waste barrel;

[0052] Step 2: Start the rotating motor to drive the shaftless spiral auger 2 to rotate and transport the finished plastic particles;

[0053] Step 3: During the conveying process, the electric slip ring 103 is controlled to slide repeatedly along the connecting rod 102, so that the extrusion cylinder 4001 and the extrusion film 4002 are repeatedly expanded and contracted, and the plastic particles being conveyed are squeezed to promote the conveying and screening of the plastic particles;

[0054] Step 4: Hot air is input into the drying hose 108, and the hot air passes into the first collecting cavity 10501, passes through the screening net 1002, and dries the plastic particles.

[0055] During the conveying and screening process of plastic particles, if the present invention is tilted, in order to avoid the conveying hose 1 from bending and blocking the plastic particles moving along the inner wall of the first collecting tube 105, the non-conforming plastic particles are discharged through the through hole 10502, the second collecting cavity 10601 and the discharge pipe 107, and when the feed inlet 1001 is higher than the discharge bin 3, the non-conforming plastic particles screened out are easy to accumulate on the right side of the first collecting cavity 10501 and are difficult to enter the second collecting cavity 10601. When the feed inlet 1001 is lower than the discharge bin 3, the non-conforming plastic particles are easily accumulated on the right side of the first collecting cavity 10501 and are difficult to enter the second collecting cavity 10601. The plastic particles that meet the specifications are easy to accumulate on the left side of the first collecting cavity 10501, which affects the conveying efficiency of the plastic particles that do not meet the specifications. Therefore, a separation ring 201 is provided to provide support for the conveying hose 1 to prevent the conveying hose 1 from being bent too much when the present invention is tilted, that is, to prevent the conveying hose 1 from contacting the first collecting tube 105 after bending and deformation, and the first collecting cavity 10501 is divided into a plurality of small cavities by the separation ring 201. When the present invention is tilted, the accumulated plastic particles are blocked to prevent the conveying hose 1 from being bent too much. Figure 4Taking the separating ring 201 shown as an example, when the plastic particles slide and accumulate along the inclined plane toward the right side of the first collecting cavity 10501, the plastic particles enter the second collecting cavity 10601 from the through hole 10502 on the left side of the separating ring 201; when the plastic particles slide and accumulate along the inner wall of the first collecting tube 105 toward the left side of the first collecting cavity 10501, the plastic particles enter the second collecting cavity 10601 from the through hole 10502 on the right side of the separating ring 201; the separating ring 201 separates the plastic particles that are to be accumulated together in each small cavity; at the same time, with the help of the hot air introduced by the drying hose 108, the plastic particles in each small cavity are quickly blown toward the through hole 10502, thereby assisting in the rapid screening and discharge of the plastic particles, thereby ensuring that the plastic particles that do not meet the specifications are automatically discharged through the hot air introduced by the separating ring 201 and the drying hose 108.

[0056] After the plastic pellets are pelletized, during the preliminary cooling process, some of the plastic pellets adhere to each other and are difficult to be screened. Therefore, a first interception net 202 and a second interception net 203 are provided to intercept the plastic pellets that adhere to each other. During the plastic pellet conveying process, the plastic pellets that meet the specifications pass through the first interception net 202 and the second interception net 203, enter the discharge bin 3, and are discharged from the discharge pipe 101. The plastic pellets that adhere to each other are intercepted by the first interception net 202 and the second interception net 203, and stay in the screening net 1002. During the process of contraction and extrusion of the extrusion rod 4, the detached plastic pellets enter the discharge bin 3, and the plastic pellets that are still adhered to each other are intercepted. It should be noted that the first interception net 202 is fixedly connected to the shaftless spiral auger 2 and rotates with the shaftless spiral auger 2. During this screening process, the second interception net 2 03 rotates along with the rotation of the first interception net 202. The first interception net 202 and the second interception net 203 cooperate to completely intercept the plastic particles that are stuck together. After the conveying work is completed, the electric shaft on the fixed part of the first interception net 202 is controlled to rotate clockwise from the feed inlet 1001 to the discharge bin 3, driving the second interception net 203 to rotate until it overlaps with the first interception net 202. Then the second interception net 203 stops rotating, and the interception area of ​​the second interception net 203 is opened. Subsequently, the rotating motor is controlled to rotate to drive the shaftless spiral auger 2 to rotate. The shaftless spiral auger 2 drives the first interception net 202 fixed thereto to rotate, and the second interception net 203 overlapping on the first interception net 202 rotates together, and the stuck plastic particles are conveyed from the opened part of the second interception net 203 to the discharge bin 3 for discharge.
