Technical Field
[0001] This utility model relates to the technical field of plastic pellet storage equipment, specifically a plastic pellet storage device. Background Technology
[0002] A search revealed existing technology (application number: CN202420163871.4), which describes "a disclosed plastic granule storage device that divides the storage chamber and bottom chamber by setting a partition, and uses a fan and exhaust mechanism to enhance gas flow to reduce the risk of spontaneous combustion of plastic granules." This utility model improves the overall airtightness, which is beneficial to the overall heat preservation, and also improves the uniformity of temperature distribution, thereby improving the overall preheating effect. However, existing plastic granule storage devices still have some shortcomings: First, it is difficult to effectively separate and store the granules during the storage process, which is not conducive to classification management and retrieval; second, the vibration generated during the operation of the device can easily affect the stored plastic granules, which may lead to granule damage or unstable storage; third, dust is generated during the storage and transportation of plastic granules, and existing devices lack an efficient dust filtration mechanism, which not only affects the quality of the granules but may also pollute the working environment; fourth, plastic granules are prone to accumulate in the storage box, resulting in poor material discharge and affecting work efficiency. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a plastic granule storage device.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a plastic granule storage device, comprising a bearing component, a driving component, a storage component, a dust filtering component, and a vibration component.
[0005] The load-bearing components include a housing, a guide plate, and a base. The housing is bolted to the top of the base and is used to support and accommodate other components. The top of the housing has a feed inlet to facilitate the entry of plastic granules into the device. The guide plate is symmetrically and vertically welded to both sides of the inner wall of the housing, and the guide plate is set at an inclined angle to guide the plastic granules to fall smoothly and prevent the granules from accumulating at the feed inlet.
[0006] The drive assembly is installed inside the housing, with guide grooves on both sides. The drive assembly includes a slide rail, a drive motor, a reciprocating screw, and a partition plate. The slide rail is bolted to one side of the housing and supports and guides the movement of other movable parts. Slider blocks are located on both sides of the partition plate, passing through the guide grooves on the housing and connecting to the slide rail. The sliders and slide rail form a sliding connection, allowing for smooth sliding along the slide rail's axial direction. The drive motor is located at one end of the slide rail and is coaxially connected to the reciprocating screw via a coupling. The reciprocating screw rotates against the inner wall of the slide rail through deep groove ball bearings at both ends. The drive motor drives the reciprocating screw to rotate, causing the partition plate to reciprocate within the housing, thus achieving separate storage of materials for easy classification, management, and retrieval.
[0007] The storage assembly, located at the bottom of the drive assembly, includes a storage tank and spring shock absorbers. The storage tank has a longitudinally spaced partition plate inside for further separation and storage of the plastic granules. The top opening of the storage tank precisely aligns with the bottom of the partition plate of the drive assembly, facilitating the introduction of granules into the storage tank. The spring shock absorbers are symmetrically arranged and fixedly connected to the top and inner sides of the storage tank via fixing plates. Each spring shock absorber contains a compression spring and a damper. Both ends of the damper are connected to the fixing plate, and the compression spring is fitted over the damper. The spring shock absorbers effectively reduce the impact of vibrations generated during device operation on the storage tank, ensuring the stability of the stored plastic granules and preventing granule damage. The storage tank also includes a discharge valve located at one end. The valve connects to the storage tank using a quick-release clamp structure and a silicone sealing ring for dustproof sealing, facilitating discharge and preventing dust ingress.
[0008] The dust filtration assembly includes a fan, a screen, a filter box, and a filter screen. The fan is located at one end of the box, with an outlet pipe connected to its output end. The bottom of the outlet pipe extends through and into the inner cavity of the box. The fan's input end is connected to an intake pipe. The screen is located at one end of the fan and is connected to the fan's inlet via a quick-release latch, allowing for preliminary filtration of larger particles. The filter box is located on the right side of the top of the base. The top of the filter box is connected to the intake pipe, and an air intake port is located at the bottom right side of the filter box. The filter box has an internal groove through which the filter screen is slidably connected. One end of the filter screen extends through and into one end of the filter box, and is secured to a handle with bolts. The fan generates airflow, drawing dust or impurities from inside the box. After initial filtration by the screen, the dust or impurities are further filtered by the filter screen, effectively purifying the air, ensuring the quality of plastic particles, and improving the working environment.
[0009] The vibration assembly is located at the bottom of the storage assembly and includes a stepper motor, a reducer, a drive shaft, a support base, a vibration seat, and an eccentric wheel. The stepper motor is located at the top of the base and is rotatably connected to the drive shaft via the reducer. The support base is rotatably mounted on the drive shaft via bearings. Eccentric wheels are symmetrically mounted on the drive shaft, and a vibration seat is mounted upwards on the outer circumference of the eccentric wheels via bearings. The stepper motor drives the drive shaft to rotate through the reducer, causing the eccentric wheels to rotate and generate vibration. This vibration is transmitted to the vibration seat, which in turn causes the storage box to vibrate, preventing plastic particles from accumulating inside the storage box, ensuring smooth material discharge, and improving work efficiency.
[0010] The present invention has the following beneficial effects: 1. The present invention can effectively separate and store plastic particles by means of the reciprocating motion of the partition plate in the drive assembly, which facilitates classification management and retrieval, and improves the orderliness and convenience of storage.
[0011] 2. This utility model utilizes a spring shock absorber in the storage component to significantly reduce the impact of vibrations generated during device operation on the storage box, ensuring stable storage of plastic granules and preventing damage to the granules due to vibration.
[0012] 3. This utility model utilizes a dust filtration component, in which the fan, screen, and filter work together to efficiently filter dust and impurities inside the device, ensuring the quality of plastic granules while improving the working environment and reducing dust pollution.
[0013] 4. This utility model relies on a vibration component, with stepper motor, reducer, eccentric wheel and other components working together to make the storage box vibrate. This vibration can effectively destroy the friction and adhesion between plastic particles, prevent the particles from clumping together due to mutual compression and adsorption during long-term storage, and ensure that the particles always maintain a good loose state and maintain their original physical properties.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0025] The specific implementation method of this utility model's plastic granule storage device is as follows: Figures 1 to 6The components are described in detail, including the load-bearing component 1, the drive component 2, the storage component 3, the dust filter component 4, and the vibration component 5. Example
[0026] The supporting component 1 includes a housing 11, a guide plate 12, and a base 13. The housing 11 is bolted to the top of the base 13 and is used to support and accommodate other components. The top of the housing 11 has a feed inlet 14 to facilitate the entry of plastic particles into the device. The guide plate 12 is symmetrically and vertically welded to both sides of the inner wall of the housing 11, and the guide plate 12 is set at an inclined angle to guide the plastic particles to fall smoothly and prevent the particles from accumulating at the feed inlet 14.
[0027] The drive assembly 2 is installed inside the housing 11. Guide grooves are provided on both sides of the housing 11. The drive assembly 2 includes a slide rail 21, a drive motor 22, a reciprocating screw 23, and a partition plate 24. The slide rail 21 is bolted to one side of the housing 11 and is used to support and guide the movement of other movable parts. The partition plate 24 has sliders on both sides. The sliders pass through the guide grooves on the housing 11 and are connected to the slide rail 21. The sliders and the slide rail 21 form a sliding connection and can slide smoothly along the axial direction of the slide rail 21. The drive motor 22 is located at one end of the slide rail 21 and is coaxially connected to the reciprocating screw 23 through a coupling. The reciprocating screw 23 is rotated with the inner wall of the slide rail 21 through deep groove ball bearings at both ends. The drive motor 22 drives the reciprocating screw 23 to rotate, thereby causing the partition plate 24 to reciprocate within the housing 11, realizing the separate storage of materials and facilitating classification management and retrieval.
[0028] The storage component 3 is located at the bottom of the drive component 2 and includes a storage box 31 and spring shock absorbers 32. The storage box 31 has a longitudinally spaced partition plate inside, which further separates the plastic granules for storage. The top opening of the storage box 31 precisely aligns with the bottom of the partition plate 24 of the drive component, facilitating the partition plate 24 to guide the granules into the storage box 31. The spring shock absorbers 32 adopt a symmetrical layout and are fixedly connected to the top of the storage box 31 and the inner side of the box body 11 via fixing plates. Each spring shock absorber 32 contains a compression spring and a damper. The two ends of the damper are connected to the fixing plate, and the compression spring is sleeved on the outside of the damper. The spring shock absorbers 32 effectively reduce the impact of vibrations generated during device operation on the storage box 31, ensuring the stability of plastic granule storage and preventing granule damage. The storage box 31 also includes a discharge valve 33, which is located at one end of the storage box 31. The connection between the discharge valve 33 and the storage box 31 uses a quick-release clamp structure, and a silicone sealing ring achieves a dustproof seal, facilitating discharge and preventing dust from entering. Example
[0029] Based on Example 1, in order to further reduce the dust content inside the box, a dust filter component was installed at one end of the base.
[0030] The dust filtration assembly 4 includes a fan 41, a screen 42, a filter box 43, and a filter screen 44. The fan 41 is located at one end of the housing 11, and its output end is connected to an air outlet pipe. The bottom of the air outlet pipe extends through and into the inner cavity of the housing 11. The input end of the fan 41 is connected to an air intake pipe. The screen 42 is located at one end of the fan 41 and is connected to the air inlet of the fan 41 via a quick-release latch. It can initially filter larger particles of impurities. The filter box 43 is located on the right side of the top of the base 13. The top of the filter box 43... The filter box 43 is connected to the suction pipe. The bottom right side of the filter box 43 has an air intake. The inside of the filter box 43 has a sliding groove. The filter screen 44 is slidably connected inside the sliding groove. One end of the filter screen 44 passes through and extends to one end of the filter box 43. One end of the filter screen 44 is fixed to the handle by bolts. The fan 41 generates airflow to draw out the dust or impurities inside the box 11. After preliminary filtration by the screen 42, the air is further filtered by the filter screen 44, which effectively purifies the air, ensures the quality of plastic particles, and improves the working environment.
[0031] The vibration assembly 5 is located at the bottom of the storage assembly 3 and includes a stepper motor 51, a reducer 52, a drive shaft 53, a support base 54, a vibration seat 55, and an eccentric wheel 56. The stepper motor 51 is located at the top of the base 13 and is rotatably connected to the drive shaft 53 via the reducer 52. The support base 54 is rotatably mounted on the drive shaft 53 via bearings. The eccentric wheels 56 are symmetrically mounted on the drive shaft 53, and a vibration seat 55 is mounted upwards on the outer circumference of the eccentric wheels 56 via bearings. The stepper motor 51 drives the drive shaft 53 to rotate via the reducer 52, causing the eccentric wheels 56 to rotate and generate vibration. The vibration is transmitted to the vibration seat 55, which in turn drives the storage box 31 to vibrate, preventing plastic particles from accumulating inside the storage box 31, ensuring smooth material discharge, and improving work efficiency.
[0032] In actual use, the box 11 is fixed on the base 13, forming the basic frame of the device. Plastic granules enter the device through the feed port 14 at the top of the box 11. The guide plates 12, which are symmetrically inclined on both sides of the inner wall of the box, can guide the granules to fall smoothly and avoid accumulation at the feed port 14, so that the granules enter the device smoothly.
[0033] When the granules enter the housing 11, the drive assembly 2 starts working, the drive motor 22 starts, and drives the reciprocating screw 23 to rotate through the coupling. Since the reciprocating screw 23 and the inner wall of the slide rail 21 are rotated through the deep groove ball bearing, and the sliders on both sides of the partition plate 24 are slidably connected to the slide rail 21, the partition plate 24 will reciprocate along the axial direction of the slide rail 21 inside the housing 11 when the reciprocating screw 23 rotates. This movement mode can separate and store the plastic granules entering the housing 11, separating granules of different types, batches or specifications, which is convenient for subsequent classification management and retrieval.
[0034] After being separated by the drive component, the plastic granules fall into the storage component 3 below. The longitudinal partition plate inside the storage box 31 further refines the storage area, enabling more detailed classification and storage of the plastic granules. The top opening of the storage box 31 is precisely aligned with the bottom of the partition plate 24 to ensure that the granules can be smoothly introduced. During the operation of the device, the spring shock absorber 32 plays an important role. Its built-in compression spring and damper work together to effectively reduce the impact of the vibration generated by the operation of the device on the storage box 31, ensuring the stability of the plastic granule storage and preventing the granules from being damaged by vibration. When it is necessary to discharge the material, the discharge valve 33 at one end of the storage box 31 uses a quick-release clamp structure and a silicone sealing ring to facilitate the discharge operation and to achieve a dustproof seal when closed, preventing external dust from entering.
[0035] Throughout the storage process, the dust filter assembly 4 continuously safeguards the storage environment. The fan 41 generates airflow, drawing out dust or impurities generated inside the housing 11 due to particle movement. First, the mesh 42 performs preliminary filtration of the air, intercepting larger particles and protecting subsequent filtration components. Then, the air enters the filter box 43, where the internal filter 44 performs deep filtration, separating fine dust and impurities. The purified air is then re-sent to the inner cavity of the housing 11 through the exhaust pipe of the fan 41, forming an air circulation purification system. This effectively reduces the dust content inside the housing, ensures the quality of the plastic particles, and improves the working environment.
[0036] Meanwhile, the vibration assembly 5 continues to operate to prevent material from clumping. After the stepper motor 51 adjusts the speed and torque through the reducer 52, it drives the transmission shaft 53 to rotate. The eccentric wheel 56 mounted on the transmission shaft 53 rotates accordingly. The centrifugal force generated by the rotation of the eccentric wheel 56 drives the vibration seat 55 to vibrate at high frequency and transmits the vibration to the storage box 31, continuously breaking the friction and adhesion between the particles, preventing the plastic particles from clumping due to long-term storage, and ensuring that the particles always maintain a good loose state.
[0037] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific implementation of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
