Description

Technical Field

[0001] This utility model belongs to the field of plastic granule processing technology, and in particular relates to a conveying device for plastic granule processing. Background Technology

[0002] In the plastic granule processing industry, conveying refers to the process of transferring plastic raw material granules (or powders, recycled materials, etc.) from storage points and feeding points to the feed inlets of downstream processing equipment (such as injection molding machines, extruders, blow molding machines, etc.). Conveying is not just simple handling, but a controlled, organized, usually continuous and automated material flow process. It is a key link in achieving stable, efficient, and high-quality production of plastic granules.

[0003] There are many types of conveying devices on the market. For example, a plastic granule conveying device with publication number CN220181888U is disclosed on the China Patent website. This conveying device can be used for material conveying in plastic granule processing, but it has some defects and shortcomings that need to be improved: (1) Some existing conveying devices lack diversion function. When conveying plastic granules, they can often only convey materials to a single feeding point through a single conveying channel. This makes the conveying pressure of the conveying channel and the feeding point relatively large. Once the number of plastic granules is large, it is easy to cause material blockage. (2) When conveying plastic granules, some existing conveying devices often cause plastic granules to come into direct contact with the inner wall of the conveying channel and collide. This causes some soft plastic granules (such as low-density polyethylene) to be scratched or broken due to repeated friction and compression, which in turn affects the subsequent processing of plastic granules. Therefore, in view of the above problems, the conveying device for plastic granule processing provided by this utility model is of great significance. Utility Model Content

[0004] This invention provides a conveying device for processing plastic granules. The airflow generated by the pneumatic conveying mechanism can push the plastic granules in each conveying channel to move along the conveying channel, so as to pneumatically convey the plastic granules. Multiple diversion chambers can divert the plastic granules, so as to distribute the plastic granules and introduce them into multiple conveying channels simultaneously. The diverted plastic granules can be simultaneously conveyed to multiple feeding points by the pneumatic conveying mechanism, thereby effectively reducing the conveying pressure of each conveying channel and feeding point, and preventing material blockage when the amount of plastic granules is large. The protective sleeve can protect the plastic granules in each conveying channel from wear, so as to prevent the plastic granules from directly contacting the inner wall of the conveying channel during pneumatic conveying and causing collisions. This prevents the surface of some soft plastic granules (such as low-density polyethylene) from being scratched or broken due to repeated friction and compression. In summary, this invention solves the problems in the background technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses a conveying device for processing plastic granules, comprising a base, a fixed frame fixedly connected to the top of the base, a feed hopper fixedly connected to the upper top surface of the fixed frame, and a diversion chamber fixedly connected to the lower top surface of the fixed frame. The top opening of the diversion chamber is connected to the feed hopper, and several conveying channels are fixedly connected to its bottom. Several partitions are fixedly connected to the inner wall of the diversion chamber, dividing the interior of the diversion chamber into several diversion cavities. An air conveying mechanism is provided on the side wall of the fixed frame. A protective sleeve is installed in each conveying channel. Several support seats are fixedly connected to the top of the base, and several grooves are opened on the top surface of each support seat.

[0007] The air delivery mechanism includes a blower and an air delivery chamber. The blower is mounted on a base and has an air delivery pipe installed on it. The air delivery chamber is mounted on the side wall of the fixed frame near the conveying channel, and several air delivery pipes are fixedly connected to the side wall of the air delivery chamber. The end port of each air delivery pipe is installed on the corresponding conveying channel and communicates with the inner cavity of the conveying channel. The end port of the air delivery pipe passes through the fixed frame and the side wall of the air delivery chamber and communicates with the inner cavity of the air delivery chamber.

[0008] Furthermore, the conveying channel is L-shaped with a circular cross-section, and the top opening of each conveying channel is connected to the inner cavity of the diversion chamber and is distributed linearly at equal intervals along the length of the top surface of the diversion chamber. The number of diversion chambers is the same as that of the conveying channels, and each diversion chamber is located directly above the top opening of each conveying channel.

[0009] Furthermore, a pair of guide blocks are fixedly connected to the bottom of the inner cavity of the diversion chamber. The guide blocks are located below each partition, with their tops being inclined end faces. The guide blocks are symmetrically distributed on the left and right sides of the top openings of each conveying channel.

[0010] Furthermore, the number of air delivery pipes is the same as the number of conveying channels, and the connection between the air delivery pipes and the conveying channels is located on the L-shaped top sidewall of the conveying channel.

[0011] Furthermore, the protective sleeve is cylindrical, with its outer diameter corresponding to the inner diameter of the conveying channel, and the inner wall of the protective sleeve located in the conveying channel is an inclined end face.

[0012] Furthermore, the protective sleeve protrudes outward at one end edge outside the conveying channel and is fixedly connected with several studs. Each stud is threaded with a nut that matches it. At the end of each conveying channel, the pipe opening edge protrudes outward and is provided with several positioning holes. The number of positioning holes is the same as that of the studs, and their diameters correspond to the diameters of the studs. The center of each positioning hole corresponds one-to-one with the center of each stud.

[0013] Furthermore, the support bases are equidistantly linearly distributed along the length of the conveying channel, the slots are arc-shaped slot structures and are equidistantly linearly distributed along the length of the top surface of each support base, and the diameter of the slots is equal to the outer diameter of the conveying channel, and the bottom end of each conveying channel is fitted into the corresponding slot.

[0014] The present invention has the following advantages over the prior art:

[0015] (1) When the conveying device for processing plastic granules in this utility model is in use, the airflow generated by the pneumatic conveying mechanism can push the plastic granules in each conveying channel to move along the conveying channel so as to pneumatically convey the plastic granules. The plastic granules can be diverted through multiple diversion chambers so as to distribute the plastic granules and synchronously introduce them into multiple conveying channels. The plastic granules after diversion can be synchronously conveyed to multiple feeding points through the pneumatic conveying mechanism, thereby effectively reducing the conveying pressure of each conveying channel and feeding point to prevent the blockage phenomenon when the amount of plastic granules is large.

[0016] (2) When the plastic particle processing conveying device of the present invention is used, the protective sleeve can protect the plastic particle material in each conveying channel from wear, so as to prevent the plastic particles from directly contacting the inner wall of the conveying channel during pneumatic conveying and causing collisions, which would cause some soft plastic particles (such as low-density polyethylene) to be scratched or broken due to repeated friction and squeezing.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] Please see Figure 1-7As shown, a conveying device for processing plastic granules according to this utility model includes a base 1, a fixed frame 2 fixedly connected to the top of the base 1, a feed hopper 3 fixedly connected to the upper top surface of the fixed frame 2, and a diversion chamber 4 fixedly connected to the lower top surface of the fixed frame 2. The top opening of the diversion chamber 4 is connected to the feed hopper 3, and several conveying channels 5 are fixedly connected to its bottom. Several partitions 6 are fixedly connected to the inner wall of the diversion chamber 4, and the partitions 6 divide the interior of the diversion chamber 4 into several diversion cavities 7. The plastic granules to be conveyed can be introduced into the diversion chamber 4 through the feed hopper 3. After entering the diversion chamber 4, the plastic granules can enter the respective conveying channels 5 through the respective diversion cavities 7. The side wall of the fixed frame 2 is provided with an air conveying mechanism. Each conveying channel 5 is equipped with a protective sleeve 8. Several support seats 9 are fixedly connected to the top of the base 1, and several grooves 10 are opened on the top surface of each support seat 9.

[0031] The pneumatic conveying mechanism includes a blower 11 and an air delivery chamber 12. The blower 11 is mounted on the base 1, and an air delivery pipe 13 is installed on the blower 11. The air delivery chamber 12 is mounted on the side wall of the fixed frame 2 near the conveying channel 5, and several air delivery pipes 14 are fixedly connected to the side wall of the air delivery chamber 12. The end port of each air delivery pipe 14 is installed on the corresponding conveying channel 5 and communicates with the inner cavity of the conveying channel 5. The end port of the air delivery pipe 13 passes through the fixed frame 2 and the side wall of the air delivery chamber 12 and communicates with the inner cavity of the air delivery chamber 12. By driving the blower 11, air can be blown to generate airflow. The airflow can be introduced into the air delivery chamber 12 through the air delivery pipe 13 and into the corresponding conveying channel 5 through each air delivery pipe 14. At this time, the airflow can be used to push the plastic granules in each conveying channel 5 to move along the conveying channel 5 so as to pneumatically convey the plastic granules. When the plastic granules are discharged from the other end of the conveying channel 5, the conveying work is completed.

[0032] The conveying channel 5 is L-shaped with a circular cross-section. The top opening of each conveying channel 5 is connected to the inner cavity of the diversion chamber 4 and is equidistantly distributed linearly along the length of the top surface of the diversion chamber 4. The number of diversion chambers 7 is the same as that of the conveying channels 5, and each diversion chamber 7 is located directly above the top opening of each conveying channel 5. After the plastic particles enter the diversion chamber 4, they can enter the corresponding diversion chamber 7. At this time, the plastic particles can be diverted through multiple diversion chambers 7 so that the plastic particles can be distributed and synchronously introduced into multiple conveying channels 5. Then, the plastic particles in multiple conveying channels 5 can be synchronously transported to multiple feeding points through the pneumatic conveying mechanism, thereby effectively reducing the conveying pressure of each conveying channel 5 and feeding point to prevent material blockage when the amount of plastic particles is large.

[0033] The bottom of the inner cavity of the diversion chamber 4 is fixedly connected to a pair of guide blocks 15. The guide blocks 15 are located below each partition 6, and their tops are inclined end faces. The guide blocks 15 are symmetrically distributed on the left and right sides of the top opening of each conveying channel 5. When the plastic granules fall onto the guide blocks 15 after diversion, they can slide quickly along the top inclined end face of the guide blocks 15 to the top opening of each conveying channel 5, so as to prevent the plastic granules from accumulating at the bottom of the diversion chamber 4 and causing blockage.

[0034] The number of air delivery pipes 14 is the same as that of the conveying channels 5, and the connection between the air delivery pipes 14 and the conveying channels 5 is located on the L-shaped top side wall of the conveying channel 5. When the airflow generated by the air delivery mechanism is used to pneumatically convey the plastic particles in each conveying channel 5, it can prevent the plastic particles from accidentally entering the air delivery pipes 14 and causing blockage.

[0035] The protective sleeve 8 is cylindrical, with its outer diameter corresponding to the inner diameter of the conveying channel 5. The inner wall of the protective sleeve 8 located in the conveying channel 5 is inclined. The protective sleeve 8 can be made of elastic materials such as rubber. When the protective sleeve 8 is installed in each conveying channel 5, its outer wall can fit against the inner wall of the protective sleeve 8. At this time, the protective sleeve 8 can protect the plastic granules from wear, so as to prevent the plastic granules from directly contacting the inner wall of the conveying channel 5 during pneumatic conveying and causing collisions. This would result in some soft plastic granules (such as low-density polyethylene) being scratched or broken due to repeated friction and compression.

[0036] The protective sleeve 8 protrudes outward at one end edge outside the conveying channel 5 and is fixedly connected with several studs 16. Each stud 16 is threaded with a nut 17 that mates with it. The end of each conveying channel 5 has several positioning holes 18 protruding outward at its end edge. The number of positioning holes 18 is the same as the number of studs 16, and their diameters correspond to the diameters of the studs 16. The center of each positioning hole 18 corresponds one-to-one with the center of each stud 16. When the protective sleeve 8 is inserted into the conveying channel 5, each stud 16 can be aligned and pass through the corresponding positioning hole 18. At this time, the nut 17 is threaded onto each stud 16 and tightened. The protective sleeve 8 is fixed by the mutual cooperation between the studs 16, positioning holes 18, and nuts 17 to prevent it from loosening. When the protective sleeve 8 is damaged due to long-term use, the protective sleeve 8 can be removed from the conveying channel 5 by unscrewing the nuts 17 for quick replacement of the damaged protective sleeve 8.

[0037] Among them, the support bases 9 are distributed linearly at equal intervals along the length of the conveying channel 5, and the grooves 10 are arc-shaped groove structures, which are distributed linearly at equal intervals along the top surface of each support base 9. The diameter of the grooves 10 is equal to the outer diameter of the conveying channel 5. The bottom end of each conveying channel 5 is attached to the corresponding groove 10. The grooves 10 on the top surface of each support base 9 can effectively support each conveying channel 5 to prevent the conveying channel 5 from bending downward and deforming after being subjected to force for a long time, thus affecting the conveying effect of plastic particles.

[0038] The circuits, electronic components, and chip modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0039] All standard parts used in the application documents can be purchased from the market. All components in this application document can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The electrical components mentioned in this document are all electrically connected to the external main controller and power supply, and the main controller is a conventional known device that can play a control role.

[0040] The working principle of this utility model is as follows:

[0041] In use, the plastic granules to be conveyed are fed into the diversion chamber 4 through the feed hopper 3. After entering the diversion chamber 4, the plastic granules can enter the corresponding diversion cavity 7 and then enter the respective conveying channel 5 through each diversion cavity 7. At this time, the plastic granules can be diverted through multiple diversion cavities 7 to distribute and synchronously introduce them into multiple conveying channels 5. Then, the blower 11 is driven to generate airflow. The airflow can be introduced into the air guide chamber 12 through the air guide pipe 13 and then into the corresponding conveying channel 5 through each air delivery pipe 14. At this time, the airflow can push the plastic granules in each conveying channel 5 to move along the conveying channel 5, so as to pneumatically convey the plastic granules. When the plastic granules are discharged from the other end of the conveying channel 5... After that, the conveying work can be completed. The plastic granules that have been diverted can be simultaneously conveyed to multiple feeding points through the pneumatic conveying mechanism, which can effectively reduce the conveying pressure of each conveying channel 5 and feeding point, so as to prevent the blockage phenomenon when the amount of plastic granules is large. Each conveying channel 5 is equipped with a protective sleeve 8. The protective sleeve 8 can protect the plastic granules from wear and prevent them from directly contacting the inner wall of the conveying channel 5 during pneumatic conveying and causing collisions. This can cause some soft plastic granules (such as low-density polyethylene) to be scratched or broken due to repeated friction and compression. When the protective sleeve 8 is damaged due to long-term use, the protective sleeve 8 can be removed from the conveying channel 5 by unscrewing the nut 17, so that the damaged protective sleeve 8 can be quickly replaced.
