Abstract
Description
Technical Field
[0001] This utility model relates to the field of reinforced nylon particle production technology, specifically a packaging structure for reinforced nylon particles. Background Technology
[0002] Reinforced nylon granules are high-performance engineering plastic granules formed by adding reinforcing materials and additives to nylon resin and then modifying it. Reinforcing materials typically include glass fiber, carbon fiber, and mineral fillers, which mainly enhance one or more properties of nylon, such as strength, rigidity, electrical conductivity, thermal conductivity, heat resistance, flame retardancy, and toughness. After the reinforced nylon is blended and extruded, it undergoes processes such as pelletizing, drying, sieving, and testing before reaching the final packaging process. The packaging process is mainly divided into two parts: the first part is to pack the reinforced nylon granules into woven bags, ton bags, or other packaging, while simultaneously weighing them for accurate measurement; the second part is to seal the packaging using methods such as sewing and heat sealing to ensure airtightness and prevent the reinforced nylon granules from falling out during transportation and causing waste. After packaging, the granules can be stacked and stored in the warehouse or loaded onto trucks for sale to customers.
[0003] In existing reinforced nylon granule packaging structures, the bagging section typically uses components such as unloading valves and baffles to control the opening and closing of the bottom of the storage tank to bag the reinforced nylon granules. When the reinforced nylon granules enter the bag, they are mainly subjected to downward gravity and freely accumulate inside the packaging. When the reinforced nylon granules freely accumulate, their slope will form a stable maximum angle, called the angle of repose, resembling a hill. When the accumulation angle exceeds the angle of repose, the upper layer of granules will slide off because the component of gravity exceeds the static friction force. The upper layer of reinforced nylon granules tends to scatter around the packaging rather than inside. Existing solutions usually use smoothing or vibration to process the reinforced nylon granules inside the packaging to prevent further accumulation of the angle of repose. However, such methods subject the reinforced nylon granules and packaging to external forces, which in turn affect the bottom weighing device. Applying too much force may cause the weighing device to complete the weighing prematurely and end the bagging process, making the operation quite cumbersome. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a reinforced nylon particle packaging structure to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a reinforced nylon granule packaging structure, comprising a base, storage tanks connected to the top two sides of the base, and supports connected to the bottom two sides of the storage tanks via tension springs and guide rods; a compensation pipe connected between the supports and the storage tanks, and a binding rope sleeved on the outside of the compensation pipe; a distribution plate connected to the bottom of the supports, with a material drop hole at the top of the distribution plate and a temporary storage opening at the bottom of the distribution plate; fully enclosed electric cylinders installed on both sides of the bottom of the supports, with baffles connected to the output ends of the fully enclosed electric cylinders; and a vibration motor installed on the top of the supports.
[0006] By adopting the above technical solution, during the bagging process, the reinforced nylon granules in the storage tank will fall into the support under the influence of gravity. The distribution plate will block the reinforced nylon granules, allowing them to be discharged simultaneously from multiple discharge holes. Compared to a single discharge hole, multiple discharge holes disperse the kinetic energy and collision area of the reinforced nylon granules, dissipating energy evenly over a larger area. The resistance to lateral movement of the reinforced nylon granules is relatively reduced, and they are easier to spread outwards when piled up, thus forming a gentler slope and avoiding the formation of a single high point, thereby suppressing the maximum angle of repose. Furthermore, the vibration motor, in conjunction with the tension spring, causes the support and distribution plate to vibrate up and down at high frequency, preventing the reinforced nylon granules from getting stuck in the discharge holes and preventing the phenomenon of reinforced nylon granules not being evenly distributed in the support and being discharged simultaneously from multiple discharge holes. During this process, the guide rod guides the support and prevents the support from falling off. The compensation pipe is a pipe with excellent elasticity, which can compensate for the change in the distance between the storage tank and the support through its own deformation during the up and down vibration of the support, preventing the reinforced nylon granules from falling out of the support and storage tank. Material leakage between tanks causes waste. When the weighing device detects that the weight of the woven bag has reached the standard, the weighing device outputs an analog or digital signal to the external PLC controller. The external PLC controller then processes the signal and outputs an analog signal to the relay to control the fully enclosed electric cylinder. The fully enclosed cylinder pushes the baffle to move, and after the baffle moves, it blocks the bottom of multiple dropping holes and temporary storage ports, preventing the reinforced nylon particles from falling further. Since the diameter of the temporary storage port is larger than the diameter of the dropping hole, the space around the contact area between the baffle and the distribution plate increases when the baffle moves laterally. For example, if it originally fell vertically downwards, it can now fall downwards at an angle or upwards into the temporary storage port. This provides more space for the reinforced nylon particles to adjust their position, reducing the possibility of them being squeezed into narrow gaps. Furthermore, the electric cylinder is fully enclosed, preventing nylon particles, dust, and other impurities from entering and increasing wear. The fully enclosed electric cylinder also has good vibration isolation, preventing the vibration generated by the vibrating motor from affecting the fully enclosed electric cylinder.
[0007] Furthermore, the compensation tube is made of TPU material, and the binding rope is made of stainless steel wire.
[0008] By adopting the above technical solution, the compensation pipe is a pipe with excellent elasticity. It can compensate for the change in the distance between the storage tank and the support through its own deformation during the up-and-down vibration of the support, thus avoiding the loss of reinforced nylon particles between the support and the storage tank and causing waste.
[0009] Furthermore, multiple material discharge holes and temporary storage ports are provided, and the multiple material discharge holes and temporary storage ports are distributed in a ring array.
[0010] By adopting the above technical solution, the reinforcing nylon particles are blocked by the distribution plate, so that the reinforcing nylon particles are discharged simultaneously from multiple discharge holes. Compared with a single discharge hole, multiple discharge holes disperse the kinetic energy and collision area of the reinforcing nylon particles, and the energy dissipation is evenly distributed over a larger area. The resistance to the lateral movement of the reinforcing nylon particles is relatively reduced, and they are easier to spread to the surroundings when piled up, thus forming a gentler slope and avoiding the formation of a single high point, thereby suppressing the maximum angle of repose.
[0011] Furthermore, the diameter of the temporary storage port is larger than the diameter of the discharge hole, and the discharge hole is connected to the temporary storage port.
[0012] By adopting the above technical solution, since the diameter of the temporary storage opening is larger than the diameter of the discharge hole, when the bottom diameter of the discharge hole is enlarged, the space around the contact area between the baffle and the distribution plate increases. When the baffle moves laterally, for example, the reinforced nylon particles can change from falling vertically downwards to falling downwards into the woven bag or from falling upwards into the temporary storage opening, there is more space for the reinforced nylon particles to adjust their position, reducing the possibility of being squeezed into narrow gaps.
[0013] Furthermore, the baffle is slidably connected to the bottom of the distribution plate, and there are four fully enclosed electric cylinders and four baffles, which are arranged in a ring array.
[0014] By adopting the above technical solution, the fully enclosed cylinder pushes the baffle to move. After the baffle moves, it blocks the bottom of multiple material drop holes and temporary storage ports, preventing the reinforced nylon particles from falling further.
[0015] Furthermore, the bracket is slidably connected to the guide rod.
[0016] By adopting the above technical solution, the support and the material distribution plate are made to vibrate up and down at high frequency by a vibration motor and a tension spring. During this process, the guide rod guides the support and prevents the support from falling off.
[0017] Furthermore, the top of the storage tank is connected to a feed inlet.
[0018] By adopting the above technical solution, the reinforced nylon granules after pelleting, drying and screening are fed into the feed inlet in advance by the lifting equipment, and then the reinforced nylon granules fall into the storage tank.
[0019] Furthermore, a weighing device is installed at the top center of the base, and a woven bag is placed on top of the weighing device.
[0020] By adopting the above technical solution, the weight of the woven bags is measured by a weighing device. If the weight meets the standard, the fully enclosed electric cylinder is activated; if the weight does not meet the standard, the bagging process continues.
[0021] Furthermore, there are six tension springs and six guide rods, and the six tension springs and guide rods are arranged in a circular array.
[0022] By adopting the above technical solution, and by increasing the number of tension springs and guide rods, the number of support points for the bracket is increased, thereby improving the support area and support strength, and preventing the bracket from falling off and experiencing vibration difficulties.
[0023] In summary, the present invention has the following main advantages:
[0024] 1. This utility model, through the arrangement of a support, a distribution plate, and discharge holes, allows the reinforced nylon granules in the storage tank to fall into the support under the influence of gravity. The distribution plate then blocks the reinforced nylon granules, allowing them to be discharged simultaneously from multiple discharge holes. Compared to a single discharge hole, multiple discharge holes disperse the kinetic energy and collision area of the reinforced nylon granules, dissipating energy evenly over a larger area. This reduces the resistance to lateral movement of the reinforced nylon granules, making it easier for them to spread outwards when piled up, thus forming a gentler slope and avoiding the formation of a single high point, thereby suppressing the maximum angle of repose. This effectively prevents the reinforced nylon granules from piling up too high, improving the storage efficiency of the woven bags.
[0025] 2. This utility model, through the setting of a temporary storage port, a fully enclosed cylinder, and a baffle, allows the fully enclosed cylinder to push the baffle to move after bagging is completed. After the baffle moves, it blocks multiple discharge holes and the bottom of the temporary storage port, preventing the reinforced nylon particles from continuing to fall. Furthermore, since the diameter of the temporary storage port is larger than the diameter of the discharge holes, the space around the contact area between the baffle and the distribution plate increases as the diameter of the discharge holes expands. When the baffle moves laterally, for example, instead of falling vertically downwards into the woven bag at an angle, the reinforced nylon particles can fall at an angle upwards into the temporary storage port, allowing more space for them to adjust their position and reducing the possibility of being squeezed into narrow gaps. This also facilitates the control of bagging start and stop.
[0026] 3. This utility model, through the arrangement of a compensating pipe, tension spring, guide rod, and vibrating motor, utilizes the vibrating motor in conjunction with the tension spring to cause the support and distributing plate to vibrate up and down at high frequency during the bagging process. This prevents reinforced nylon granules from getting stuck in the discharge holes and avoids the phenomenon of reinforced nylon granules not being evenly distributed in the support and being discharged simultaneously from multiple discharge holes. During this process, the guide rod guides the support and prevents it from falling off. The compensating pipe, being a highly elastic pipe, can compensate for changes in the distance between the storage tank and the support through its own deformation during the up and down vibration of the support, preventing the reinforced nylon granules from leaking between the support and the storage tank and causing waste. This increases the stability of the structure during operation and reduces the occurrence of blockages. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0033] The embodiments of this utility model will be described below based on its overall structure.
[0034] Example 1:
[0035] A reinforced nylon particle packaging structure, such as Figures 1-4As shown, the system includes a base 1, with storage tanks 2 connected to the top two sides of the base 1. Supports 7 are connected to the bottom two sides of the storage tanks 2 via tension springs 14 and guide rods 15. The bottom diameter of the guide rod 15 is smaller than its top diameter, and the bottom of the guide rod 15 is threaded and fitted with a nut. The support 7 is slidably connected to the guide rod 15. A compensation pipe 6, made of TPU material, connects the support 7 to the storage tanks 2. A binding rope 8, made of stainless steel wire, is fitted around the outside of the compensation pipe 6. A vibration motor 16 is installed on the top of the support 7. The vibration motor 16, in conjunction with the tension springs 14, causes the support 7 and the distribution plate 9 to vibrate up and down at high frequency, thereby preventing the reinforced nylon particles from getting stuck in the discharge hole 10 and preventing the reinforced nylon particles from remaining inside the support 7. The material is simultaneously discharged from multiple discharge holes 10. During this process, the guide rod 15 guides the support 7 and prevents it from falling off. The compensation pipe 6 is a highly elastic pipe that can compensate for the change in the distance between the storage tank 2 and the support 7 through its own deformation during the up-and-down vibration of the support 7, thus preventing the reinforced nylon particles from being lost between the support 7 and the storage tank 2 and wasting them. A distribution plate 9 is connected to the bottom of the support 7. The top of the distribution plate 9 has a discharge hole 10, and the bottom of the distribution plate 9 has a temporary storage port 11. There are multiple discharge holes 10 and temporary storage ports 11. The multiple discharge holes 10 and temporary storage ports 11 are arranged in a ring array. The diameter of the temporary storage port 11 is larger than the diameter of the discharge hole 10. During the bagging process, the reinforced nylon granules in the storage tank 2 will fall into the support 7 due to gravity. The distribution plate 9 will block the granules, allowing them to be discharged simultaneously from multiple discharge holes 10. Compared to a single discharge hole 10, multiple discharge holes 10 disperse the kinetic energy and collision area of the reinforced nylon granules, dissipating energy more evenly over a larger area. This reduces the resistance to lateral movement of the nylon granules, making them easier to spread outwards during accumulation, thus forming a gentler slope and preventing the formation of a single high point, thereby suppressing the maximum angle of repose. Fully enclosed electric cylinders 12 are installed on both sides of the bottom of the support 7. The output end of the fully enclosed electric cylinder 12 is connected to a baffle 13, which is slidably connected to the bottom of the distribution plate 9. There are four fully enclosed electric cylinders 12 and four baffles 13. The four fully enclosed electric cylinders 12 and baffles 13 are arranged in a ring array. The fully enclosed cylinders push the baffles 13 to move. After the baffles 13 move, they block the bottom of multiple dropping holes 10 and temporary storage ports 11 to prevent the reinforced nylon particles from falling. Since the diameter of the temporary storage port 11 is larger than the diameter of the dropping holes 10, when the bottom diameter of the dropping holes 10 is enlarged, the space around the contact area between the baffles 13 and the distribution plate 9 increases. When the reinforced nylon particles move laterally on the baffles 13, for example, they can change from falling vertically downwards to falling downwards into the woven bag 5 or from falling upwards into the temporary storage port 11. There is more space for the reinforced nylon particles to adjust their position, reducing the possibility of them being squeezed into narrow gaps.Furthermore, the electric cylinder is fully enclosed, preventing impurities such as nylon particles and dust from entering and increasing wear. The fully enclosed electric cylinder 12 also has good vibration isolation, preventing vibrations generated by the vibrating motor 16 from affecting the fully enclosed electric cylinder 12.
[0036] See Figure 1 In the above embodiment, the top of the storage tank 2 is connected to the inlet 3, and the base 1 is equipped with a weighing device 4 in the middle of the top. A woven bag 5 is placed on the top of the weighing device 4. The reinforced nylon granules, after being granulated, dried and screened, are fed into the inlet 3 in advance by the lifting device, and then the reinforced nylon granules fall into the storage tank 2. The workers place the woven bag 5 or other packaging containers on the top of the weighing device 4, and then the workers limit the woven bag 5 by hand or by purchasing automatic bag clamps, robots and other automatic equipment to prevent the woven bag 5 from collapsing and running in the early stage and affecting the bagging of reinforced nylon granules. When it is almost full, the limit of the woven bag 5 can be stopped to avoid affecting the weighing accuracy. At this time, the weight of the woven bag 5 is measured by the weighing device 4. If the weight reaches the standard, the fully enclosed electric cylinder 12 is opened. If the weight does not reach the standard, the bagging work continues.
[0037] Example 2:
[0038] Based on the above embodiment one, the following settings are now adopted to increase structural stability.
[0039] See Figures 1-4 In the above embodiment, six tension springs 14 and six guide rods 15 are provided. The six tension springs 14 and guide rods 15 are arranged in a circular array. By increasing the number of tension springs 14 and guide rods 15, the number of support points for the bracket 7 is increased, the support area and support strength are improved, and the phenomenon of bracket 7 falling off and vibration difficulties is avoided.
[0040] The implementation principle of this utility model is as follows: First, the reinforced nylon granules after pelleting, drying and screening are fed into the feed inlet 3 by the lifting equipment, and then the reinforced nylon granules fall into the storage tank 2; the workers place the woven bag 5 or other packaging container on the top of the weighing device 4, and then the workers limit the woven bag 5 by hand or by purchasing automatic bag clamps, robots and other automatic equipment to prevent the woven bag 5 from collapsing and running in the early stage and affecting the bagging of the reinforced nylon granules; when it is almost full, the limiting of the woven bag 5 can be stopped to avoid affecting the weighing accuracy. At this time, the weight of the woven bag 5 is measured by the weighing device 4. If the weight reaches the standard, the fully enclosed electric cylinder 12 is opened. If the weight does not reach the standard, the bagging work continues.
[0041] During the bagging process, the reinforced nylon granules in the storage tank 2 will fall into the support 7 due to gravity. The distribution plate 9 will block the granules, allowing them to be discharged simultaneously from multiple discharge holes 10. Compared to a single discharge hole 10, multiple discharge holes 10 disperse the kinetic energy and collision area of the reinforced nylon granules, dissipating energy evenly over a larger area. This reduces the resistance to lateral movement of the nylon granules, making them easier to spread outwards during accumulation, thus forming a gentler slope and avoiding the formation of a single high point. This suppresses the maximum angle of repose. Furthermore, the vibration... The machine 16, in conjunction with the tension spring 14, causes the support 7 and the distribution plate 9 to vibrate up and down at high frequency, thereby preventing the reinforced nylon particles from getting stuck in the discharge hole 10 and preventing the reinforced nylon particles from being discharged simultaneously from multiple discharge holes 10 without being spread evenly in the support 7. During this process, the guide rod 15 guides the support 7 and prevents the support 7 from falling off. The compensation pipe 6 is a pipe with excellent elasticity, which can compensate for the change in the distance between the storage tank 2 and the support 7 through its own deformation during the up and down vibration of the support 7, thus preventing the reinforced nylon particles from being lost between the support 7 and the storage tank 2 and causing waste.
[0042] When the weighing device 4 detects that the weight of the woven bag 5 has reached the standard, the weighing device 4 outputs an analog or digital signal to the external PLC controller. The external PLC controller then processes the signal and outputs an analog signal to the relay to control the fully enclosed electric cylinder 12. The fully enclosed cylinder pushes the baffle 13 to move, and after the baffle 13 moves, it blocks the bottom of the multiple discharge holes 10 and the temporary storage port 11, preventing the reinforced nylon particles from continuing to fall. Furthermore, since the diameter of the temporary storage port 11 is larger than the diameter of the discharge holes 10, when the bottom diameter of the discharge holes 10 expands... After the baffle 13 is enlarged, the space around the contact area between the baffle 13 and the distribution plate 9 is increased. When the reinforced nylon particles move laterally on the baffle 13, for example, instead of falling vertically downwards into the woven bag 5, they can fall downwards at an angle or enter the temporary storage port 11 at an angle. There is more space for the reinforced nylon particles to adjust their position, reducing the possibility of them being squeezed into narrow gaps. In addition, the electric cylinder is fully enclosed, which prevents impurities such as nylon particles and dust from entering and increasing wear. The fully enclosed electric cylinder 12 also has a good vibration isolation effect, which prevents the vibration generated by the vibration motor 16 from affecting the fully enclosed electric cylinder 12.
