Description

Technical Field

[0001] This application relates to the field of epoxy prepreg resin adhesive technology, and in particular to a quick-freezing packaging system. Background Technology

[0002] Epoxy prepreg resin is a type of one-component epoxy prepreg adhesive formulated from epoxy resin base, latent curing agent, diluent, accelerator, etc. It is popular due to its good adhesion, wide range of applications, relatively low price, low curing shrinkage, good fatigue resistance, and lack of volatile solvents, resulting in less environmental and human harm. One-component epoxy prepreg resin adhesives do not require mixing with a curing agent and can be used directly, simplifying operation. They also have a long working time at room temperature and can be rapidly cured by heating, making them suitable for bonding complex structures. When combined with carbon fiber, one-component adhesives can be used to create carbon fiber prepreg fabric, which is ultimately applied to recreational sports equipment such as carbon fiber fishing rods, carbon fiber badminton rackets, and carbon fiber bicycles.

[0003] In the packaging process of single-component epoxy prepreg resin adhesives, the adhesives are typically first batched into small, individual packages, then manually moved to cold storage for cooling and setting, followed by bagging and sealing, box sealing, stacking and wrapping, and finally storage in a cold storage facility. These operations require manual labor and are time-consuming, resulting in low packaging efficiency for single-component epoxy prepreg resin adhesives. Therefore, there is an urgent need for equipment capable of rapidly packaging single-component epoxy prepreg resin adhesives to improve packaging efficiency. Utility Model Content

[0029] Please see Figure 1 and Figure 2 This application provides a quick-freezing packaging system 100 for quick-freezing single-component epoxy prepreg resin adhesive in some embodiments. The quick-freezing packaging system 100 includes a conveyor 10, a cooling mechanism 20, and a packaging transfer mechanism 30. The conveyor 10 is used to convey the parts to be processed; the cooling mechanism 20 is installed above the conveyor 10 and cools and shapes the parts to be processed, completing the cooling process after the parts pass through the cooling mechanism 20; the packaging transfer mechanism 30 is connected to the cooling mechanism 20 and transfers and packages the cooled parts to be processed.

[0030] The conveyor 10 can be, but is not limited to, belt conveyor or chain conveyor. The conveyor 10 can transport the workpieces to be processed back and forth between multiple workstations. The cooling mechanism 20 can be used to quickly freeze the workpieces arriving within its working range. The packaging and transfer mechanism 30 packages the cooled workpieces and transfers them to a storage point.

[0031] The working principle of the quick-freezing packaging system 100 will be explained below, taking the single-component epoxy prepreg resin adhesive as an example.

[0032] The conveyor 10 sequentially transports the items to be processed through the bagging station, weighing and dispensing station, sealing station, and quick-freezing station. The bagging machine 11 at the bagging station can bag the items to be processed. The weighing and dispensing station is equipped with components such as an automatic electronic scale and a dispensing extruder 12 to weigh and dispense the bagged items, controlling the weight error between different items to within ±1g. The sealing station has an automatic bag-folding and sealing machine 13 to seal the bags and check the seal's tightness. When the sealed items arrive at the quick-freezing station, the cooling mechanism 20 quickly freezes and shapes them.

[0033] Finally, the packaging and transfer unit 30 packs the multiple frozen and shaped parts together and then transfers them to cold storage or other storage locations for storage.

[0034] In summary, the aforementioned quick-freezing packaging system 100 utilizes the collaborative operation of multiple components to quick-freeze and package the items to be processed, thereby improving the processing efficiency of the items to be processed, reducing the degree of manual intervention, and increasing the automation level of the quick-freezing packaging system 100.

[0035] In some embodiments, the conveyor 10 may be configured as a circular conveyor belt and is independent of the running track of the packaging transfer mechanism 30. A cooling mechanism 20 is disposed in a portion of the circular conveyor belt. The conveyor 10 is provided with a tray for supporting items to be processed, which can support the items to be processed as they move along the circular conveyor belt. After the items to be processed are transferred by the packaging transfer mechanism 30 via the cooling mechanism 20, the empty tray can flow back to the bagging machine 11 and other stations to support the next item to be processed and carry it between different stations.

[0036] In some embodiments, the cooling mechanism 20 includes a base 21 and a cooling assembly 22. The base 21 has a receiving cavity 211, the conveyor 10 passes through the receiving cavity 211, the cooling assembly 22 is disposed in the receiving cavity 211 and has a spray nozzle 221, the spray nozzle 221 is disposed toward the conveyor 10 to spray liquid nitrogen onto the conveyor 10.

[0037] The base 21 is used to support components such as the cooling assembly 22. Because liquid nitrogen can produce a temperature of -196°C when it evaporates at low temperatures, it can rapidly lower the temperature of objects in a short time. Furthermore, liquid nitrogen is an inert gas, non-toxic and non-flammable, and does not produce pollutants during use, meeting food safety and environmental protection requirements.

[0038] When the workpiece enters the receiving cavity 211, the liquid nitrogen ejected from the injection port 221 causes the temperature inside the receiving cavity 211 to drop rapidly to -180°C to -196°C. In this way, the workpiece can be cooled and solidified after entering the receiving cavity 211. The required quick-freezing time for the workpiece at the above temperature is generally 1 min to 2 min.

[0039] For example, when the bagging machine 11 bags four packages per minute, the cooling component 22 can quickly freeze and set 5 kg / piece of single-component adhesive at -180°C, with a freezing time of no more than 2 minutes. When the bagging machine 11 bags five packages per minute, the cooling component 22 can quickly freeze and set 5 kg / piece of single-component adhesive at -185°C, with a freezing time of approximately 1.5 minutes.

[0040] It should be noted that since the part to be processed is still in the feeding state after entering the receiving cavity 211, that is, on the way to the next station by the conveyor 10, the set length of the receiving cavity 211 along the conveyor belt direction is the freezing time of the part to be processed.

[0041] This setup allows for quick-freezing of the parts being processed while they are being transported, cooling them without delaying the delivery of the parts and accelerating the required freezing time.

[0042] In some embodiments, the cooling assembly 22 includes a liquid supply component 222, a first cooling component 223, and a second cooling component 224. The liquid supply component 222 is used to store liquid nitrogen. The liquid supply component 222 is connected to the first cooling component 223 and the second cooling component 224. Along the vertical direction X, the first cooling component 223 and the second cooling component 224 are located on both sides of the conveying component 10. Both the first cooling component 223 and the second cooling component 224 have a spray nozzle 221.

[0043] The liquid supply unit 222 is used to store liquid nitrogen and transport it to the first cooling unit 223 and the second cooling unit 224. Because the first cooling unit 223 and the second cooling unit 224 are located on both sides of the conveying unit 10 along the vertical direction X, that is, the first cooling unit 223 and the second cooling unit 224 are located at different parts of the receiving cavity 211, which can simultaneously cool different parts of the receiving cavity 211, thereby accelerating the rate at which the temperature inside the receiving cavity 211 drops to the preset temperature and accelerating the cooling rate of the workpiece to be processed.

[0044] In some embodiments, the first cooling member 223 is located below the conveying member 10, and the receiving cavity 211 is further provided with a collecting member 225. The collecting member 225 is located below the first cooling member 223, and along the vertical direction X, the orthographic projection of the first cooling member 223 and the orthographic projection of the second cooling member 224 both fall within the opening of the collecting member 225.

[0045] For example, both the first cooling element 223 and the second cooling element 224 extend along the conveying direction of the conveyor 10. The opening of the collector 225 faces the conveyor 10, and along the vertical direction X, the orthographic projections of the first cooling element 223 and the second cooling element 224 both fall within the opening range of the collector 225. When liquid nitrogen in aerosol form adheres to the surface of components such as the cooling elements and the conveyor 10 and accumulates to form water droplets, and drips under gravity, it can fall into the collector 225 through the opening for recycling.

[0046] Specifically, in some embodiments, a baffle 226 is also provided in the receiving cavity 211. The baffle 226 and the second cooling member 224 are located on the same side of the conveyor 10. Along the conveying direction of the conveyor 10, the baffle 226 is located on one side of the second cooling member 224. The distance between the baffle 226 and the conveyor 10 is less than the distance between the second cooling member 224 and the conveyor 10. Moreover, along the vertical direction X, the orthographic projection of the baffle 226 falls into the opening of the collecting member 225.

[0047] For example, a baffle 226 is disposed on the inner wall of the receiving cavity 211 and extends in the vertical direction X. The end of the baffle 226 away from the receiving cavity 211 is disposed closer to the conveyor 10 relative to the second cooling member 224. The baffle 226 and the second cooling member 224 are spaced apart, and the orthographic projection of both falls within the opening of the collecting member 225 in the vertical direction X.

[0048] When liquid nitrogen is sprayed from the nozzle 221 of the second cooling element 224, the baffle 226 can block the liquid ammonia mist that is close to it, so that it falls into the collection element 225 as much as possible for recycling, thereby improving the recovery rate.

[0049] More specifically, in some embodiments, the first cooling element 223 and the second cooling element 224 are each provided with a plurality of spray nozzles 221 at intervals along the conveying direction of the conveyor 10.

[0050] In this way, liquid nitrogen can be ejected from different nozzles 221 at the same time, which shortens the time required for the containment cavity 211 to be filled with liquid nitrogen per unit time, shortens the time required for the temperature in the containment cavity 211 to drop sharply, and improves the quick-freezing efficiency.

[0051] Furthermore, in some embodiments, the seat 21 is provided with an exhaust 212, which connects the receiving cavity 211 to the outside.

[0052] For example, the top of the base 21 has a through hole, which is configured as an exhaust vent 212 and connected to an external exhaust pipe to discharge the liquid nitrogen in the containment cavity 211 in the form of aerosol. This reduces the amount of liquid nitrogen remaining in the containment cavity 211 and reduces the risk of oxygen deficiency in the workshop due to excessive nitrogen caused by liquid nitrogen spreading into the workshop where the quick-freezing packaging system 100 is located.

[0053] It should be noted that an exhaust fan can also be installed around the through hole to accelerate the gas flow rate in the receiving cavity 211, thereby speeding up the discharge of residual liquid nitrogen in the receiving cavity 211.

[0054] Furthermore, in some embodiments, the cooling assembly 22 also includes an adjustment element 227 located at the outlet of the liquid supply element 222 and used to adjust the flow rate and pressure.

[0055] The regulating component 227 may include a booster pump and a regulating valve. One end of the booster pump is connected to the regulating valve, and the other end is connected to the liquid supply component 222. Liquid nitrogen flowing out of the liquid supply component 222 is pressurized by the booster pump and then flows to the regulating valve. The regulating valve can adjust the amount of liquid nitrogen flowing to the first cooling component 223 and the second cooling component 224, thereby controlling the amount of liquid nitrogen entering the receiving cavity 211, so as to make reasonable use of liquid nitrogen, minimize liquid nitrogen loss, and save liquid nitrogen consumption.

[0056] In some embodiments, the packaging transfer mechanism 30 includes a first transfer member 31 and a packaging device 32. The first transfer member 31 is used to transfer the cooled items to be processed to the packaging device 32, and the packaging device 32 performs packaging operations.

[0057] For example, the first transfer component 31 may be configured as a robotic arm, and the packaging equipment 32 may include components such as a carton opener 321, a carton sealer 322, a labeling machine 323, and a carton packing machine 324. The carton opener 321, the carton sealer 322, the labeling machine 323, and the carton packing machine 324 are sequentially arranged at preset workstations on the production line.

[0058] Carton erector 321 automatically folds cardboard pieces into complete cartons and seals the bottom; it can fold cartons of different sizes as needed. A robotic arm picks up the quick-frozen and shaped parts and places them into the folded cartons. Carton sealing machine 322 and labeling machine 323 then seal and label the cartons. Carton packing machine 324 then packs the labeled cartons.

[0059] The packaging and transfer mechanism 30 also includes a palletizing robot 325, a pallet packing machine 326, and a stretch wrapping machine 327. The palletizing robot 325 can stack the packed cartons on a pallet. After a certain number of cartons are stacked on the pallet, the pallet packing machine 326 and the stretch wrapping machine 327 sequentially perform packing and stretch wrapping operations on the cartons carried by the pallet to protect the cartons and provide fixation, moisture protection, and dust protection.

[0060] This configuration further enhances the automation level of the quick-freezing packaging system 100 and improves its working efficiency.

[0061] In some embodiments, the packaging transfer mechanism 30 further includes a second transfer member 33, which is used to transfer the packaged items to be processed to a cold storage point.

[0062] An Automated Guided Vehicle (AGV) can be used as the second transfer unit 33 to transport the packaged cartons to a cold storage facility for refrigeration, thus improving transportation flexibility. The AGV can be powered by a lithium battery, allowing it to operate continuously for more than 8 hours.

[0063] Furthermore, the aforementioned quick-freezing packaging system 100 may also include an intelligent monitoring device to monitor each component in real time and issue alarms. Compared to a quick-freezing packaging system 100 without an intelligent monitoring device, this results in a fault warning accuracy rate of 95%, a 30% reduction in the average downtime of all components, and a 20% improvement in the overall production plan's alignment with market demand.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
