Description

Technical Field

[0001] This invention relates to sorting machines applied in the field of logistics conveying technology, and more specifically to a cargo drying module and a sorting machine assembly having the module. Background Technology

[0002] In logistics transportation, sorting machines are needed to sort and transport goods, such as the multi-layer sorting assembly disclosed in Chinese Patent Publication No. CN213287696U. Sorting machines typically transport goods via conveyor belts formed by rollers or belts. However, in practical use, it has been found that when goods become wet due to weather conditions (e.g., from rain or dampness), or accidentally become wet, the presence of water between the goods and the conveyor belt can cause slippage during sorting. This significantly reduces the accuracy and stability of goods sorting and transportation, resulting in a substantial decrease in overall transportation efficiency.

[0003] Based on this, it is considered to include a cargo drying module in the sorting machine assembly to dry the cargo when its surface becomes wet due to weather conditions or accidents. However, existing cargo drying devices, such as the cargo dryer disclosed in CN105403026A, often fail to adequately adapt to the characteristics of logistics transportation to provide targeted drying that meets the needs of rapid cargo transport. Summary of the Invention

[0004] One of the objectives of this invention is to address the shortcomings of existing technologies by providing a cargo drying module that is adapted to logistics and transportation needs and can perform targeted drying of cargo to better meet the requirements of rapid cargo transportation.

[0005] The second objective of this invention is to provide a sorting machine assembly having the aforementioned cargo drying module, so as to optimize the accuracy and stability of cargo sorting and transportation when cargo is affected by weather or gets wet due to accidents.

[0006] The technical solution of the present invention is as follows: Cargo drying module, including: A conveyor belt assembly for transporting goods has a plurality of rollers arranged at intervals, the plurality of rollers including: adjacent first rollers and second rollers; A hot air blower for outputting hot airflow includes: an air outlet duct that directs the output of hot airflow from the air outlet; The air outlet duct is inserted between the first and second rollers, and the air outlet of the duct is set upwards, so that: When goods are being transported on the conveyor belt assembly, the lower end face of the goods that comes into contact with the conveyor belt can be dried.

[0007] As a further preferred embodiment, the air outlet is arranged with one side higher and the other side lower in the direction from the first roller to the second roller; Furthermore, the air outlet is equipped with a sealing plate to block the air outlet; The sealing plate has several guide holes, which are inclined and extended to guide the hot airflow in the air outlet duct obliquely upward to the area above the second roller.

[0008] As a further preferred embodiment, the second roller is provided with a plurality of flow guiding notches spaced apart on the axis of the second roller; The guide notch is a groove provided on the outer surface of the second roller and surrounding the outer periphery of the second roller.

[0009] As a further preferred embodiment, an air duct is provided on the side of the second roller facing away from the first roller; The air duct has an inlet that is positioned toward the second roller and allows airflow to enter the air duct, and an outlet that allows airflow to exit the air duct. Furthermore, an exhaust fan is installed inside the exhaust duct, which is configured to generate an airflow that flows from the exhaust port to the exhaust port.

[0010] As a further preferred option, the inlet is configured to be higher than the axis of the second roller.

[0011] As a further preferred embodiment, an air duct is provided on the side of the second roller facing away from the first roller; The air duct has an inlet that is positioned toward the second roller and allows airflow to enter the air duct, and an outlet that allows airflow to exit the air duct. Furthermore, the outlet is connected to the air inlet of the hot air blower.

[0012] As a further preferred option, the inlet is configured to be higher than the axis of the second roller.

[0013] As a further preferred option, when there are N rollers, there are N-1 hot air blowers; Furthermore, a hot air blower outlet duct is fitted between any two adjacent rollers.

[0014] As a further preferred option, when there are N rollers, the hot air blower is equipped with N-1 air outlet ducts. Furthermore, an air outlet duct is fitted between any two adjacent rollers.

[0015] The sorting machine assembly includes the goods drying module described in any of the above embodiments, and a sorting machine having a feed conveyor channel for goods input. The cargo drying module is placed in the feeding conveyor channel so that it can dry the cargo conveyed to the sorting machine.

[0016] The main beneficial effects of the above technical solution are as follows: Based on the characteristics of cargo sorting and transportation, a cargo drying module is incorporated into the conveyor belt assembly used for transporting goods. Specifically, a hot air blower is installed between two adjacent rollers, capable of blowing hot air upwards. This allows for targeted drying of the lower surface of the goods that comes into contact with the conveyor belt during transport, improving the dryness of the lower surface and reducing the likelihood of slippage due to water. When this cargo drying module is used in the sorting machine assembly, it ensures rapid cargo transport while minimizing slippage, thereby optimizing the accuracy and stability of cargo sorting and transportation.

[0017] Further or more detailed beneficial effects will be described in conjunction with specific embodiments in the detailed implementation. Attached Figure Description

[0028] The present invention will be specifically illustrated below with reference to embodiments: Example 1: In existing cargo sorting systems, cargo A is typically transported via a conveyor belt structure formed by rollers or belts. The conveyor direction is changed at a certain location to sort cargo A into different areas. However, in practical use, it has been found that when cargo A becomes wet due to weather conditions (e.g., getting wet from rain or dampness), or accidentally becomes wet, the presence of water between cargo A and the conveyor belt causes slippage during sorting. This significantly reduces the accuracy and stability of cargo A sorting and transport, resulting in a substantial decrease in overall transport efficiency.

[0029] Therefore, there is a need for a cargo drying module for use in cargo sorting systems, which aims to dry cargo a in order to prevent it from slipping and thus improve the accuracy and stability of cargo a sorting and transportation.

[0030] Based on the characteristics of the existing logistics transportation structure, when goods 'a' are transported in a cargo sorting system via a transport line composed of several interconnected conveyor belts, their lower end remains in contact with the conveyor belts. Therefore, the humidity or moisture content of the lower end of goods 'a' significantly affects the stability of its contact with the conveyor belts. When the humidity or moisture content of the lower end of goods 'a' is high, goods 'a' is prone to slipping during transport on the conveyor belts, especially when goods 'a' need to be transported from one conveyor belt to another or when the transport direction of goods 'a' is changed. However, the humidity or moisture content of other ends of goods 'a', such as the upper or side ends, generally does not have a significant impact on whether goods 'a' slips.

[0031] Based on the above analysis, when drying goods a to improve the accuracy and stability of sorting and transportation by preventing slippage, the primary focus should be on drying the lower surface of goods a during transport. However, existing goods a drying structures, such as the goods a dryer disclosed in CN105403026A, are often unable to meet these requirements. Furthermore, if the aforementioned structure is used to dry the lower surface of goods a, the goods a must first be kept stationary, which significantly reduces the overall sorting and transportation efficiency.

[0032] Therefore, in order to solve the above two problems at the same time, this embodiment provides a cargo drying module that is adapted to logistics and transportation and can perform targeted drying of cargo a while better meeting the needs of rapid transportation of cargo a.

[0033] For details, see attached. Figure 1As shown, the drying module for goods a in this embodiment first includes a conveyor belt assembly 1 for transporting goods a. It includes two spaced-apart supports 1.1, and a plurality of rollers 1.2 are arranged in the space between the two supports 1.1 to place goods a and drive the goods a forward. The plurality of rollers 1.2 are arranged at intervals, and one end of each roller 1.2 is rotatably connected to one support 1.1, and the other end is rotatably connected to the other support 1.1, so that each roller 1.2 can rotate. Simultaneously, the plurality of rollers 1.2 are connected to each other by a transmission belt 1.3, a transmission chain, or a transmission gear, so that the plurality of rollers 1.2 rotate synchronously. Each roller 1.2 is driven to the output shaft of a rotary motor (not shown in the figure) that provides rotational power, so that when the rotary motor is powered on, it can synchronously drive the plurality of rollers 1.2 to rotate in one direction, thereby driving the goods a placed on that roller 1.2 to move forward and transport the goods a.

[0034] Meanwhile, as attached Figure 2 As shown, this embodiment also includes a hot air blower 2 for outputting hot airflow, which includes a blower housing 2.1 with an internal cavity. The blower housing 2.1 has an air inlet 2.11 for external air to enter the internal cavity of the blower housing 2.1, and an air outlet duct 2.12 with an internal cavity structure. One end of the air outlet duct 2.12 is connected to the internal cavity of the blower housing 2.1, and the other end has an air outlet 2.12a. This allows the air outlet duct 2.12 to guide the air in the internal cavity of the blower housing 2.1 to the air outlet 2.12a and discharge it.

[0035] Furthermore, a fan assembly is installed within the internal cavity of the fan housing 2.1. This fan assembly includes a first rotary motor 2.2 for providing rotational power, which has a first rotary output shaft that outputs rotational power by rotation; it also includes a first impeller 2.3 fixed to the first rotary output shaft. The first rotary motor 2.2 drives the first impeller 2.3 to rotate, allowing air on one side of the first impeller 2.3 (inlet side) to flow to the other side (outlet side), thus forming an airflow. In this embodiment, the inlet side of the first impeller 2.3 faces the inlet port 2.11, and the outlet side faces the outlet duct 2.12, so that the fan assembly is configured to generate an airflow from the inlet port 2.11 to the outlet port 2.12a when rotating. By energizing or de-energizing the first rotary motor 2.2, the fan assembly can either generate the aforementioned airflow or cease operation.

[0036] An electric heating plate 2.4, which is energized for heating, is installed between the air outlet side of the first impeller 2.3 and the air outlet duct 2.12. The electric heating plate 2.4 is provided with an air passage 2.41 through which airflow from the fan housing 2.1 passes and flows to the air outlet duct 2.12. By energizing or de-energizing the electric heating plate 2.4, heating can be enabled or disabled.

[0037] When needed, the first rotating motor 2.2 is powered on, and the heating plate 2.4 is also powered on, so that air can enter the fan housing 2.1 from the air inlet 2.11, flow through the heating plate 2.4 to exchange heat and form a hot airflow, which is discharged outward from the air outlet 2.12a of the air outlet duct 2.12.

[0038] Meanwhile, as attached Figure 2 As shown, in this embodiment, the air outlet duct 2.12 is inserted between the first roller 1.21 and the second roller 1.22, and the air outlet 2.12a of the air outlet duct 2.12 is arranged facing upwards, so that when goods a are transported on the conveyor belt assembly 1, the lower end surface of the goods a in transport that is in contact with the conveyor belt can be dried.

[0039] In this way, during the movement of goods a on the conveyor belt assembly 1, the hot air blower 2 operates, blowing hot air upwards through the air outlet 2.12a of the air outlet duct 2.12. When goods a passes through the area between the first roller 1.21 and the second roller 1.22, the hot air blows hot air onto the bottom of goods a, drying the lower surface of goods a that contacts the conveyor belt, thus increasing the dryness of the lower surface of goods a and reducing the possibility of goods a slipping during transport due to water. When this goods a drying module is used in the sorting machine assembly, it can reduce the possibility of goods a slipping during transport while ensuring the rapid transport of goods a, thereby optimizing the accuracy and stability of goods a sorting and transport.

[0040] As is common knowledge, when several rollers 1.2 are arranged at intervals in a first direction (e.g., horizontal direction), in a second direction perpendicular to the first direction (e.g., vertical direction), the air outlet duct 2.12 is not higher than the highest point of the first roller 1.21 and the highest point of the second roller 1.22, so as to avoid obstructing the normal transport of goods a on rollers 1.2 and to ensure that goods a can be transported smoothly on conveyor belt assembly 1.

[0041] Furthermore, considering that when hot airflow blows directly vertically upwards, it is easy to exert an upward force on cargo a, especially when some cargo a is small in weight and the impact of hot airflow is too large, it may blow cargo a up and cause its position to shift unnecessarily.

[0042] Therefore, in order to better avoid the aforementioned problems and to make the cargo drying module more suitable for drying goods of different weights, as shown in the attached document... Figure 3 As shown, in this embodiment, the end face of the air outlet 2.12 with the air outlet 2.12a is inclined, so that in the direction from the first roller 1.21 to the second roller 1.22, the air outlet 2.12a is on one side (the side closer to the first roller 1.21, for example, the side attached to the first roller 1.21). Figure 3 The left side of the roller is higher, and the other side (the side closer to the second roller 1.22, for example, attached) is higher. Figure 3 (Right side) is set low. Furthermore, the air outlet 2.12a is provided with a sealing plate 2.5 to block the air outlet 2.12a; the sealing plate 2.5 has several guide holes 2.51 for the airflow inside the air outlet duct 2.12 to be discharged outwards; as shown in the attached... Figure 3 As shown, the guide hole 2.51 extends at an angle to guide the hot airflow in the outlet duct 2.12 obliquely upward to the area above the second roller 1.22. At this time, the airflow is as follows... Figure 4 The flow is indicated by the dashed arrow.

[0043] In this way, while the lower end face of the goods a can be dried as described above, the sealing plate 2.5 with guide holes 2.51 is provided by matching the air outlet 2.12a. This not only diverts the airflow blown out of the air outlet 2.12a and reduces the impact of hot airflow on the goods when it is discharged from the air outlet 2.12, but also allows the hot airflow to be blown out of the air outlet 2.12 at an angle, reducing unwanted impact on the goods in the vertical direction.

[0044] As attached Figure 8 As shown, to match each guide hole 2.51, the outer side of the sealing plate 2.5 may also be provided with a protruding portion 2.52 located above the guide hole 2.51; in the direction from the first roller 1.21 to the second roller 1.22, the protruding portion 2.52 extends obliquely upward to guide the airflow blown out of the guide hole 2.51 to the area above the second roller 1.22. At the same time, in the direction from top to bottom, the protruding portion 2.52 covers the guide hole 2.51 to prevent impurities and water droplets on the goods from falling into the guide hole 2.51.

[0045] At the same time, by setting the guide hole 2.51, some of the blown hot air can be blown to the outer surface of the second roller 1.22. In this way, the hot air can also dry the surface of the second roller 1.22, ensuring that the second roller 1.22 can always be kept in a better dry state for better transportation of goods.

[0046] However, compared to the scheme where the hot airflow in the air outlet duct 2.12 is blown directly upwards, when the airflow in the air outlet duct 2.12 is blown obliquely upwards towards the area above the second roller 1.22, the contact area between the hot airflow and the goods is relatively smaller. The goods can only be dried by the hot airflow in the gap area between the air outlet duct 2.12 and the second roller 1.22, which leads to a reduction in the overall drying effect on goods a.

[0047] Therefore, in order to improve the overall drying effect on cargo a, as shown in the attached document... Figure 5 As shown, in this embodiment, the second roller 1.22 is provided with a plurality of guide notches 1.22a spaced apart on the axis of the second roller 1.22. The guide notches 1.22a are grooves provided on the outer surface of the second roller 1.22 and surrounding the outer periphery of the second roller 1.22. By providing the guide notches 1.22a, on the one hand, the contact area between the hot airflow and the transported goods a is increased, and the contact time between the hot airflow and the transported goods a is increased. That is, when the goods a are transported onto the second roller 1.22, the upwardly blowing hot airflow can still flow in the guide notches 1.22a to dry the lower end surface of the goods a, thereby improving the overall drying effect of the goods a. On the other hand, the contact area between the second roller 1.22 and the goods a is reduced, and the contact friction between the goods a and the second roller 1.22 is weakened, so that the goods a can be transported more smoothly.

[0048] Furthermore, as described above, when the guide gap 1.22a is provided and the goods a are transported to the second roller 1.22, the airflow blown out by the air outlet duct 2.12 will sweep obliquely upward to the lower end face of the goods a. After colliding with the lower end face of the goods a, it will disperse in all directions. Some of the hot airflow will flow out from the guide gap 1.22a, while some of the hot airflow will disperse in all directions, resulting in heat waste.

[0049] Therefore, based on the aforementioned setting of the flow guide gap 1.22a, as shown in the appendix... Figure 6 Or attached Figure 7 Furthermore, an air-guiding structure can be provided on the side of the second roller 1.22 facing away from the first roller 1.21 to guide more of the airflow blown out of the air outlet duct 2.12 through the guide gap 1.22a and flow to the side of the second roller 1.22 facing away from the first roller 1.21. This allows more airflow to contact the lower surface of the goods a, improving the drying effect of the goods a while also increasing the utilization rate of the hot airflow blown out by the hot air blower 2. On the other hand, the air-guiding structure also increases the flow velocity of the hot airflow passing through the guide gap 1.22a to a certain extent, thereby better drying the lower surface of the goods a.

[0050] In the first form, as shown in the appendix Figure 6 As shown, the second roller 1.22 faces away from the first roller 1.21 on one side (e.g., attached). Figure 6 On the right side of the first roller 1.22, an air duct 3 with an internal cavity structure is provided. The air duct 3 has an inlet 3.1 facing the second roller 1.22 and supplying airflow into the air duct 3, and an outlet 3.2 supplying airflow out of the air duct 3. An air duct fan 3.3 is provided inside the air duct 3. The air duct fan 3.3 includes a second rotary motor 3.31 for providing rotational power, which has a second rotary output shaft that outputs rotational power by rotation; it also includes a second impeller 3.32 fixed to the second rotary output shaft. The second rotary motor 3.31 drives the second impeller 3.32 to rotate, allowing air on one side of the second impeller 3.32 (inlet side) to flow to the other side (outlet side), thus forming an airflow.

[0051] In this embodiment, the air inlet side of the second impeller 3.32 is positioned towards the air inlet 3.1, and the air outlet side is positioned towards the air outlet 3.2, so that the air inlet fan 3.3 is configured to generate an airflow from the air inlet 3.1 to the air outlet 3.2, thereby enabling airflow to be directed through the air outlet duct 2.12 as described above.

[0052] At this point, it is common sense that in the second direction (e.g., the vertical direction) that is perpendicular to the first direction as described above, the air duct 3 is not higher than the highest point of the first roller 1.21 and the highest point of the second roller 1.22, so as to avoid obstructing the normal transport of goods a on roller 1.2 and to ensure that goods a can be transported smoothly on the conveyor belt assembly 1.

[0053] Furthermore, the inlet 3.1 is preferably configured to be higher than the axis of the second roller 1.22. In this way, the low-pressure airflow generated by the inlet 3.1 under the action of the airflow fan 3.3 will cause more airflow from the outlet duct 2.12 to pass through the guide notch 1.22a and flow into the airflow duct 3 from the area above the second roller 1.22. Moreover, this allows more hot airflow to be located in the area above the second roller 1.22 for better drying of the goods a.

[0054] In the second form, an air duct 3 is provided on the side of the second roller 1.22 facing away from the first roller 1.21; the air duct 3 has an inlet 3.1 facing the second roller 1.22 and supplying airflow into the air duct 3, and an outlet 3.2 supplying airflow out of the air duct 3; and the outlet 3.2 is connected to the air inlet 2.11 of the hot air blower 2 through a pipe.

[0055] Referring to the configuration of the inlet 3.1 in the first form, in the second form, the inlet 3.1 is also preferably configured to be higher than the axis of the second roller 1.22.

[0056] Compared to the first type of exhaust structure, the second type of exhaust structure not only eliminates the need for an additional exhaust fan 3.3, reducing production costs, but also allows for the reuse of some hot airflow, improving energy efficiency and meeting environmental protection requirements.

[0057] In any of the above embodiments, the conveyor belt assembly 1 is configured to transport goods a from the first roller 1.21 to the second roller 1.22.

[0058] For example, when as attached Figure 2 As shown, when the first roller 1.21 is located to the left of the second roller 1.22, several rollers 1.2 rotate clockwise under the drive of a rotating motor, so as to transport goods a from left to right; combined with the hot air blower 2 as shown in the attached figure. Figure 4 The hot airflow blowing obliquely to the upper right as shown will not hinder the transportation of goods a, but will further provide some power for the transportation of goods a, making the transportation of goods a more efficient and smooth.

[0059] Example 2: Based on the solution in Embodiment 1, it is considered that simply setting up a blowing drying area may not be able to effectively dry the goods during transportation.

[0060] Therefore, as attached Figure 9 As shown, in the cargo drying module of this embodiment, when there are N rollers 1.2, there are N-1 hot air blowers 2; and between any two adjacent rollers 1.2, an air outlet duct 2.12 of a hot air blower 2 is adapted to be inserted. This ensures that when cargo a is transported on the conveyor belt assembly 1, multiple drying points are used to dry the lower surface of cargo a, guaranteeing the drying effect of cargo a.

[0061] Example 3: Based on the solution in Embodiment 1, it is considered that simply setting up a blowing drying area may not be able to effectively dry the goods during transportation.

[0062] Therefore, as attached Figure 10 As shown, in the cargo drying module of this embodiment, when there are N rollers 1.2, the hot air blower 2 is equipped with N-1 air outlet pipes 2.12. The hot air generated in the hot air blower 2 can be simultaneously blown out from the N-1 air outlet pipes 2.12; and, an air outlet pipe 2.12 is adapted to be inserted between any two adjacent rollers 1.2. This ensures that when cargo a is transported on the conveyor belt assembly 1, there are multiple drying points to dry the lower end surface of cargo a, thus guaranteeing the drying effect of cargo a.

[0063] Example 4: Based on the above-described embodiments one, two, or three, this embodiment provides a sorting machine assembly, which includes a goods drying module as described in any of embodiments one, two, or three, and a sorting machine having a feeding conveying channel for goods input; the goods drying module is placed in the feeding conveying channel so that the goods drying module can dry the goods conveyed to the sorting machine.

[0064] For example, the sorting machine assembly in this embodiment is configured according to a multi-layer sorting assembly disclosed in Chinese Patent Publication No. CN213287696U, and the cargo drying module described in any of the above embodiments one, two, or three is part of the inlet conveyor or the outlet conveyor in the multi-layer sorting assembly. This allows for drying of the lower end surface of the cargo delivered to the sorting machine while ensuring rapid cargo transportation, reducing the possibility of cargo slippage during sorting and transportation, and thus optimizing the accuracy and stability of cargo sorting and transportation.
