Description

Technical Field

[0001] This utility model relates to the technical field of nylon material preparation, and more specifically, it relates to a raw material screening device for nylon material preparation. Background Technology

[0002] Nylon (polyamide), as a high-performance engineering plastic, is widely used in automotive parts, electronic insulation components, precision injection molded parts, and other fields. Nylon raw materials are mostly in granular or powder form. If the raw materials contain impurities or have uneven particle size, it will directly affect the stability of subsequent melting, extrusion, injection molding and other processes, ultimately leading to quality defects in the finished nylon product such as bubbles, cracks, and insufficient strength. Among them, the raw material screening device for nylon material preparation is a device specifically used for particle size screening of nylon raw materials. Its core function is to classify the raw materials according to particle size through screening components, remove unqualified particles and impurities, and provide qualified raw materials for subsequent preparation processes.

[0003] An existing raw material screening device for nylon material preparation has been found to have the following issues during use: 1. The screening components of existing devices are mostly semi-fixed and fixed by clips. However, the clips are mostly hidden inside the processing tank, and the operating space is small. Disassembly requires the use of tools to pry them, which can easily cause the clips to deform or the inner wall of the processing tank to be scratched. However, this kind of operation is cumbersome and cannot be removed quickly, resulting in poor practicality.

[0004] 2. Existing equipment mostly relies on gravity screening, that is, the raw materials pass through the screening plate by their own gravity, and there is a lack of effective power mechanism to assist screening, resulting in extremely low screening rate and poor practicality. Utility Model Content

[0005] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a raw material screening device for nylon material preparation, so as to solve the technical problems mentioned in the background art, such as cumbersome material removal after screening and poor screening rate.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a raw material screening device for nylon material preparation, comprising a box body, a processing groove provided at the top of the box body, a discharge pipe assembly provided at the bottom of the processing groove, a reserved hole provided at the front end of the processing groove, an annular plate fitted inside the reserved hole of the processing groove, the outer side of the annular plate being in close contact with the inner side of the processing groove, two slots evenly provided at the rear end of the inner side of the processing groove, positioning blocks being fitted in both sets of rear end slots of the processing groove, and the rear end of the annular plate being connected to the front end of the two sets of positioning blocks, a vibration mechanism provided inside the annular plate, a collection groove slidably provided inside the annular plate through the vibration mechanism, a screening plate provided at the bottom of the inner side of the collection groove, a fixing assembly provided at the front end of the annular plate, and the front end of the annular plate being connected to the front end of the box body through the fixing assembly.

[0007] The present invention is further configured such that the vibration mechanism includes a vibration motor, both ends of the annular plate are provided with reserved holes, the front end of the annular plate is provided with a vibration motor, and two sets of reserved holes in the annular plate are provided with spring-loaded components. Two sets of reserved holes in the annular plate are provided with connecting blocks slidably arranged through the spring-loaded components. The bottom output end of the vibration motor is connected to the top of the corresponding set of connecting blocks, and the opposite ends of the two sets of connecting blocks are connected to one end of the collection trough. The inner side of the annular plate and the outer side of the collection trough are slidably in close contact. The vibration motor, as the active power source, directly drives the connecting blocks and the collection trough to vibrate. Compared with traditional non-powered screening, the vibration intensity and frequency are greatly improved, effectively breaking the accumulation of raw materials, while ensuring that fine or easily agglomerated raw materials are fully dispersed, improving screening accuracy. The spring-loaded components and the vibration motor work together to form continuous reciprocating vibration, avoiding screening dead angles caused by a single vibration direction, so that the raw materials are subjected to force in all directions on the screening plate, further improving screening uniformity.

[0008] The present invention is further configured such that the rebound assembly includes connecting springs, and each of the two sets of annular plates has a sliding rod installed in the reserved holes. The outer sides of the two sets of sliding rods are respectively slidably fitted with a set of connecting blocks. Connecting springs are evenly arranged at the top and bottom of the outer sides of the two sets of sliding rods. The two ends of the four sets of connecting springs are respectively connected to one end of the corresponding annular plate reserved hole and one end of the connecting block. The sliding rods provide precise guidance to the connecting blocks, ensuring that the connecting blocks slide only along the axial direction of the sliding rods. This avoids lateral displacement of the connecting blocks during vibration, which could cause the collection trough to collide with the annular plate, thus ensuring the stability of the vibrating screening process. The elastic deformation and release of the connecting springs provide continuous reverse power to the connecting blocks, enhancing the reciprocating vibration effect. Compared with the single vibration relying solely on the vibration motor, this can extend the vibration duration, improve vibration uniformity, and further accelerate the raw material screening rate.

[0009] This utility model is further configured such that the fixing component includes two sets of mounting plates, with mounting plates provided on both sides of the front end of the annular plate. Both sets of mounting plates have pre-drilled holes, and each set of mounting plates has a locking block fitted into the pre-drilled holes. A connecting plate is provided at one end of each of the locking blocks. Fixing plates are provided at both ends of the top of the housing. Each set of fixing plates has a sliding groove at its top, and a connecting screw is rotatably installed within the sliding groove. A slider is threadedly connected to the outer side of each of the connecting screws. The top of each slider is connected to the bottom of a connecting plate. The locking mechanism between the locking blocks and the pre-drilled holes of the mounting plates enables rapid fixing and disassembly of the annular plate. Compared to traditional bolt fixing, it eliminates the need to disassemble bolts one by one, significantly reducing fixing and disassembly time. The threaded transmission between the connecting screw and the slider allows for precise control of the locking block's movement distance, ensuring that the locking block is fully engaged or disengaged from the pre-drilled hole. This prevents vibration and displacement of the annular plate due to inadequate fixing, or difficulty in disassembly due to locking block jamming, thus improving the reliability of the fixing component.

[0010] The present invention is further configured such that one end of each of the two sets of connecting screws passes through the slide groove of the fixing plate and is provided with a rotating handle; the rotating handle provides a convenient force application point for the rotation of the connecting screws, which can be easily rotated and reduce the operating intensity.

[0011] The present invention is further configured such that a first annular guide plate is provided at the top of the inner side of the processing tank, and a second annular guide plate is provided at the bottom of the inner side of the processing tank; the first annular guide plate effectively avoids spillage and waste when raw materials are poured in, ensuring that all raw materials to be screened enter the collection tank and improve the utilization rate of raw materials; the second annular guide plate guides qualified raw materials to converge towards the discharge pipe assembly, avoiding the residue of raw materials at the bottom of the processing tank.

[0012] The present invention is further provided with handles on both sides of the front end of the annular plate; this provides convenient force points for the installation and disassembly of the annular plate and improves operational safety.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides a raw material screening device for nylon material preparation, which has the following beneficial effects: 1. The integrated structure of the annular plate and the processing tank, combined with the double fixation of the positioning block and the fixing component, ensures that the annular plate remains stable and does not shift during the vibrating screening process. Furthermore, the annular plate can be pulled out directly by releasing the fixation, significantly shortening the cleaning time for unqualified particles and impurities. The vibration mechanism drives the collection tank to vibrate, replacing traditional gravity screening. Vibration breaks up the raw material accumulation layer, preventing screen hole blockage and significantly improving the screening rate. Simultaneously, it ensures that raw materials of the correct particle size quickly pass through the screening plate, reducing screening time. The integrated design of the collection tank and the screening plate allows raw material screening, qualified raw material collection, and unqualified material cleaning to form independent units, ensuring smooth operation and preventing raw material residue in the processing tank, reducing subsequent cleaning difficulty. It is suitable for batch screening needs of nylon raw materials.

[0014] 2. The vibrating motor, as the main power source, directly drives the connecting block and the collection tank to vibrate. Compared with traditional non-powered screening, it greatly improves the vibration intensity and frequency, effectively breaks up the accumulation of raw materials, and ensures that fine or easily agglomerated raw materials are fully dispersed, thus improving screening accuracy. The rebound component and the vibrating motor work together to form continuous reciprocating vibration, avoiding screening dead angles caused by a single vibration direction, so that the raw materials are subjected to force in all directions on the screening plate, further improving screening uniformity.

[0020] Please see Figure 1-5 A raw material screening device for nylon material preparation includes a housing 1, a processing tank 2 at the top of the housing 1, a discharge pipe assembly 3 at the bottom of the processing tank 2, a pre-drilled hole at the front end of the processing tank 2, an annular plate 4 fitted inside the pre-drilled hole, the outer side of the annular plate 4 being in close contact with the inner side of the processing tank 2, two slots evenly arranged on the rear end of the inner side of the processing tank 2, each set of two slots containing a positioning block 5, and the rear end of the annular plate 4 being connected to the front end of the two sets of positioning blocks 5, a vibration mechanism being provided inside the annular plate 4, a collection tank 6 slidingly arranged inside the annular plate 4 via the vibration mechanism, a screening plate 7 at the bottom of the inner side of the collection tank 6, a fixing assembly at the front end of the annular plate 4, and the front end of the annular plate 4 being connected to the front end of the housing 1 via the fixing assembly. In this embodiment, the annular plate 4 is inserted into the pre-drilled hole at the front end of the processing tank 2, so that the outer side of the annular plate 4 is in close contact with the inner side of the processing tank 2. At the same time, the rear end of the annular plate 4 is connected to the front ends of the two sets of positioning blocks 5 in the slot at the rear end of the inner side of the processing tank 2. The position of the annular plate 4 is initially fixed by the positioning blocks 5. The nylon raw material to be screened is poured into the collection tank 6 inside the annular plate 4, ensuring that the raw material falls onto the screening plate 7 at the bottom of the inner side of the collection tank 6. The vibration mechanism inside the annular plate 4 is activated. The vibration mechanism drives the collection tank 6 to slide and vibrate along the inner side of the annular plate 4. The raw material is separated on the screening plate 7 by the vibration. The raw material of the appropriate particle size passes through the screening plate 7 and falls into the bottom of the collection tank 6. Unqualified particles and impurities remain on the surface of the screening plate 7. The front end of the annular plate 4 is connected and fixed to the front end of the box 1 by the fixing component at the front end of the annular plate 4 to prevent the annular plate 4 from shifting during vibration. After screening, the fixing component is released and the annular plate 4 is pulled, so that the annular plate 4 drives the collection tank 6 to detach from the reserved hole of the processing tank 2, and the unqualified particles and impurities on the surface of the screening plate 7 are poured out. Then the discharge pipe assembly 3 at the bottom of the processing tank 2 is opened to discharge the qualified raw material at the bottom of the collection tank 6 through the discharge pipe assembly 3, completing one screening process.

[0021] More specifically, when fixing the annular plate 4, the connecting screws 16 in the grooves of the two sets of fixing plates 15 are rotated. The rotation of the connecting screws 16 drives the slider 17 connected by the outer thread to slide along the groove of the fixing plate 15. The top of the slider 17 drives the connecting plate 14 to move synchronously. The connecting plate 14 drives the locking block 13 at one end to approach the reserved hole of the mounting plate 12 at the front end of the annular plate 4. When the locking block 13 is fully engaged in the reserved hole of the mounting plate 12, the rotation of the connecting screws 16 is stopped. At this time, the locking block 13 is connected to the annular plate 4 through the mounting plate 12. The slider 17 and the connecting plate 14 fix the position of the locking block 13. The front end of the annular plate 4 is firmly connected to the front end of the box 1 through the fixing component to prevent the annular plate 4 from shifting during the vibrating screening process.

[0022] Please see Figure 1 and Figure 4 As one implementation of the vibration mechanism: the vibration mechanism includes a vibration motor 8, and pre-drilled holes at both ends of the annular plate 4. The vibration motor 8 is located at the front end of the annular plate 4. Rebound components are installed in both sets of pre-drilled holes in the annular plate 4, and connecting blocks 9 are slidably installed in both sets of pre-drilled holes through the rebound components. The bottom output end of the vibration motor 8 is connected to the top of the corresponding set of connecting blocks 9. The opposite ends of both sets of connecting blocks 9 are connected to one end of the collection groove 6. The inner side of the annular plate 4 slides tightly against the outer side of the collection groove 6.

[0023] Specifically, the vibration motor 8 at the front end of the annular plate 4 is started. The bottom output end of the vibration motor 8 generates a vibration force, which drives a set of connecting blocks 9 connected to it to vibrate synchronously. This set of connecting blocks 9 transmits vibration and drives another set of connecting blocks 9 to move synchronously with the spring component in the reserved hole of the annular plate 4. The two sets of connecting blocks 9 together drive the collection trough 6 to slide and vibrate along the inner side of the annular plate 4. During the vibration, the spring component expands and contracts with the vibration of the connecting blocks 9, providing a reverse elastic force to the connecting blocks 9. Under the combined action of the force of the vibration motor 8 and the elastic force of the spring component, the connecting blocks 9 drive the collection trough 6 to continuously slide and vibrate, enhancing the screening effect. When the collection trough 6 vibrates, its outer side always slides and adheres tightly to the inner side of the annular plate 4. The annular plate 4 provides a stable sliding guide for the collection trough 6, preventing the collection trough 6 from shifting or tilting during vibration, ensuring that the raw materials are evenly screened on the screening plate 7. After screening is completed, the vibration motor 8 is turned off, and the spring component drives the connecting blocks 9 and the collection trough 6 to reset, waiting for the next screening operation.

[0024] Please refer to Figures 2-4 As a further embodiment of the vibration mechanism: the rebound assembly includes connecting springs 11, and slide rods 10 are provided in the reserved holes of the two sets of annular plates 4. The outer sides of the two sets of slide rods 10 are respectively slidably fitted with a set of connecting blocks 9. Connecting springs 11 are evenly provided at the top and bottom of the outer sides of the two sets of slide rods 10. The two ends of the four sets of connecting springs 11 are respectively connected to one end of the reserved hole of the corresponding annular plate 4 and one end of the connecting block 9.

[0025] Specifically, during startup, the connecting block 9 slides along the slide rod 10 in the pre-drilled hole of the annular plate 4 under the force of the vibrating motor 8. The slide rod 10 provides a stable sliding trajectory for the connecting block 9, preventing it from deviating during sliding. During the sliding process, the connecting block 9 compresses the connecting springs 11 at the top and bottom of the slide rod 10, causing the connecting springs 11 to contract and deform. When the direction of the force of the vibrating motor 8 changes, the contracted connecting springs 11 release their elasticity, pushing the connecting block 9 to slide in the opposite direction, forming reciprocating vibration. The four sets of connecting springs 11 provide elasticity from the top and bottom of the connecting block 9 respectively, ensuring that the connecting block 9 is subjected to balanced force during sliding vibration, preventing the connecting block 9 from tilting or getting stuck due to unilateral force. The collecting trough 6 vibrates synchronously with the connecting block 9. Under the continuous reciprocating vibration, the raw materials on the screening plate 7 quickly complete particle size separation. The qualified raw materials pass through the sieve holes, while the unqualified particles remain on the surface of the screening plate 7. After the vibration stops, the connecting springs 11 return to their initial state, driving the connecting block 9 and the collecting trough 6 to return to the middle position inside the annular plate 4.

[0026] In summary, the overall equipment is in use (or running): Hold the handles 21 on both sides of the front end of the annular plate 4 with both hands, and insert the annular plate 4 into the pre-drilled hole at the front end of the processing tank 2, so that the outer side of the annular plate 4 is in close contact with the inner side of the processing tank 2. The rear end of the annular plate 4 is connected to the two sets of positioning blocks 5 in the slot at the rear end of the inner side of the processing tank 2. Rotate the rotating handle 18 at one end of the connecting screw 16 on the fixing plate 15. The connecting screw 16 drives the slider 17 to slide along the slide groove of the fixing plate 15. The slider 17 drives the locking block 13 through the connecting plate 14 to lock into the pre-drilled hole of the mounting plate 12 at the front end of the annular plate 4, thus fixing the annular plate 4.

[0027] Pour the raw material to be screened into the collection tank 6. The first annular guide plate 19 at the top of the inner side of the processing tank 2 guides the raw material into the collection tank 6 and onto the screening plate 7. Start the vibration motor 8 at the front end of the annular plate 4. The vibration motor 8 drives the connecting block 9 to slide along the slide rod 10 in the reserved hole of the annular plate 4. The connecting spring 11 on the outside of the slide rod 10 extends and retracts with the connecting block 9, so that the two sets of connecting blocks 9 drive the collection tank 6 to vibrate back and forth along the inner side of the annular plate 4. The raw material is separated on the screening plate 7: qualified raw material passes through the screen holes and is guided by the second annular guide plate 20 at the bottom of the inner side of the processing tank 2 to converge towards the discharge pipe assembly 3, while unqualified particles remain on the screening plate 7.

[0028] After screening, rotate the handle 18 in the opposite direction to disengage the locking block 13 from the mounting plate 12. Hold the handle 21 to remove the annular plate 4 from the processing tank 2, pour out the unqualified particles on the screening plate 7, and open the discharge pipe assembly 3 to discharge the qualified raw materials. Finally, reinstall the annular plate 4 back into the processing tank 2 to complete the reset.

[0029] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
