Description

Technical Field

[0001] This invention relates to the field of automated production technology, and in particular to an automatic drying device. Background Technology

[0002] Currently, most preserved fruit processing enterprises use the traditional sun-drying method, where products are directly laid on cement floors, plastic sheets, or drying trays. The spreading, turning, and collecting of the fruit embryos, as well as the cleaning of the site, are all done manually, resulting in low production efficiency, high labor intensity, high ambient temperature, and harsh working conditions for workers.

[0003] Therefore, in order to solve the above problems, technicians have accelerated the research on equipment for processing and drying preserved fruits. However, the automated drying of such equipment is still mainly based on flat laying, which occupies a huge area. For example, the above equipment generally needs to be placed in a drying room, but due to various reasons such as land shortage, the available space in the drying room is limited. However, the above equipment can only be dried by flat laying, which not only fails to make full use of the internal space of the drying room, but also severely limits the amount of preserved fruits that can be dried.

[0004] Therefore, developing a device that can make full use of the interior space of the drying room to increase the drying capacity of preserved fruits has become an urgent technical problem to be solved. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic drying device to solve the problem that existing technologies cannot fully utilize the internal space of drying rooms to increase the drying capacity of preserved fruits.

[0006] To address the aforementioned technical problems, the present invention provides an automatic drying device, comprising a lifting mechanism, a circulating drying conveyor mechanism, and a return conveyor mechanism. The lifting mechanism is used to convey materials to the circulating drying conveyor mechanism for transport. The circulating drying conveyor mechanism includes a frame, a conveyor chain mounted on the frame for circulating transport, and multiple trays mounted on the conveyor chain in a flip-out unloading manner. The circulating drying conveyor mechanism also includes a drying conveying area and an unloading conveying area arranged vertically, with the conveying path of the conveyor chain located within the drying conveying area and the unloading conveying area, and the conveying path of the conveyor chain arranged in an undulating manner within the drying conveying area. The return conveyor mechanism is used to receive materials in the unloading conveying area and return them to the lifting mechanism.

[0007] In one embodiment, the lifting mechanism is provided with a fabric conveyor belt, the conveying direction of which is arranged obliquely from bottom to top.

[0008] In one embodiment, the conveying path of the conveyor chain is arranged in multiple V-shapes within the drying conveyor area.

[0009] In one embodiment, the frame is provided with multiple sets of driven sprockets, which are respectively engaged and driven by multiple high and low transition points of the conveyor chain.

[0010] In one embodiment, each of the multiple sets of driven sprockets includes two driven sprockets, which are respectively engaged and driven by the upward conveying section and the downward conveying section of the conveying chain. The two driven sprockets are horizontally separated by an anti-interference distance, which is used to prevent interference between adjacent pallets during lifting and lowering.

[0011] In one embodiment, the V-angle formed by the conveyor chain conveying path is 55° to 65°.

[0012] In one embodiment, the return conveying mechanism includes a collecting conveyor, a lifting conveyor, and a transfer conveyor; the collecting conveyor is used to collect the material unloaded from the pallet and convey it to the lifting conveyor; the lifting conveyor is arranged obliquely from bottom to top and is used to deliver the material to the transfer conveyor; the transfer conveyor is used to deliver the material to the lifting mechanism for conveying.

[0013] In one embodiment, the transfer conveyor is a structure that can control its own drive motor to rotate in the forward and reverse directions to switch the conveying direction, and one of the conveying directions of the transfer conveyor motor points to the lifting mechanism.

[0014] In one embodiment, multiple automatic drying devices share a single transfer conveyor, the transfer conveyor's path passing through the unloading points of multiple lifting conveyors and the receiving points of multiple lifting mechanisms.

[0015] In one embodiment, the return conveying mechanism is provided with a flipping structure, which is located in the unloading conveying area. The flipping structure is used to control the flipping of the pallet, thereby sending the material to the return conveying mechanism for conveying.

[0016] The beneficial effects of this invention are as follows:

[0017] Because the conveying path of the conveyor chain is arranged in an undulating manner within the drying conveying area, this arrangement can make full use of the three-dimensional space of the drying room, thereby greatly improving the drying efficiency. Moreover, the drying conveying mechanism includes multiple trays installed on the conveyor chain in a flip-out unloading form. The return conveying mechanism is used to receive materials in the unloading conveying area and send them back to the lifting mechanism, which also realizes the automatic flipping of materials and provides a guarantee for the full drying of materials. In other words, it effectively solves the problem that the existing technology cannot make full use of the internal space of the drying room to increase the drying capacity of dried fruits.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] This invention provides an automatic drying device, the implementation of which is as follows: Figures 1 to 5 As shown, it includes a lifting mechanism 10, a circulating drying conveyor mechanism 20, and a return conveyor mechanism 30.

[0031] Regarding the lifting mechanism 10, as Figure 1 As shown, the lifting mechanism 10 is used to transport materials to the circulating drying conveyor mechanism 20 for conveying. Therefore, the main function of the lifting mechanism 10 is to realize the conveying of materials. To achieve this purpose, various commonly used transmission devices can be used, such as conveyor belts.

[0032] In this embodiment, the lifting mechanism 10 is equipped with a fabric conveyor belt 11, and the conveying direction of the fabric conveyor belt 11 is arranged obliquely from bottom to top; for example, in Figure 1 In the direction shown, the fabric conveyor belt 11 is used to transport materials from the lower left to the upper right, so that when the materials are transported to the highest point of the fabric conveyor belt 11, they can fall naturally onto the circulating drying conveyor mechanism 20 for subsequent transport.

[0033] In addition, the fabric conveyor belt 11 can be replaced with fabric of different thicknesses according to different usage requirements, and the conveying speed of the lifting mechanism 10 can be adjusted according to the fabric thickness to ensure uniform distribution of materials.

[0034] It should also be noted that the lifting mechanism 10 may also be equipped with a material trough at its lower part to achieve centralized storage of materials, and may also be equipped with baffles for uniform material distribution.

[0035] Regarding the aforementioned circulating drying conveyor mechanism 20, as Figure 1 As shown, the circulating drying conveyor mechanism 20 includes a frame 21, a conveyor chain 22 mounted on the frame 21 for circulating conveying, and a plurality of trays 23 mounted on the conveyor chain 22 in a flip-out unloading manner.

[0036] The frame 21 mentioned above is mainly used for support. Therefore, when making the frame 21, it should not only be ensured to have sufficient length to maximize the use of the horizontal space of the drying room 40, but also to have sufficient height to ensure that the vertical space of the drying room 40 can be fully utilized.

[0037] The aforementioned conveyor chain 22 is installed on the frame 21. Its arrangement extends not only from the left side of the frame 21 to the right side of the frame 21, but also from the top of the frame 21 to the bottom of the frame 21, thereby ensuring that the coverage of the conveyor chain 22 is very wide, making full use of the horizontal and vertical space inside the drying room 40.

[0038] In order to better dry the materials, the conveying paths of the conveyor chain 22 above and below are different in this embodiment. Specifically, the circulating drying conveyor mechanism 20 also includes a drying conveyor area 241 and an unloading conveyor area 242 arranged vertically. The conveying path of the conveyor chain 22 is set in the drying conveyor area 241 and the unloading conveyor area 242. The conveying path of the conveyor chain 22 is arranged in an undulating manner in the drying conveyor area 241.

[0039] The high and low undulation arrangement mentioned here refers to the fact that some of the conveying paths of the conveyor chain 22 are used for upward conveying and some for downward conveying; for example, it can be a direct alternation of upward and downward conveying; it can be a horizontal conveying distance between upward and downward conveying before changing; it can be that the upward conveying distance and the downward conveying distance and the inclination are the same; or it can be that the upward conveying distance and the downward conveying distance and the inclination are different, etc.

[0040] In this embodiment, the conveying path of the conveying chain 22 is arranged in multiple V shapes within the drying conveying area 241. Of course, the conveying chain 22 can be arranged in multiple different V shapes, but in order to ensure that the drying effect of the material is uniform in all places, the conveying chain 22 in this embodiment is arranged in multiple identical V shapes.

[0041] To further improve the uniformity of material drying, it is also important to choose a suitable V-angle. If the angle is not chosen properly, there may be too much obstruction between the trays 23, resulting in some materials not being able to dry fully.

[0042] Therefore, in this embodiment, the V-angle formed by the conveying path of the conveying chain 22 is preferably set to 60°. After selecting this setting, the mutual obstruction between the pallets 23 can be greatly reduced, thereby ensuring that the materials are fully dried. Of course, the V-angle formed by the conveying path of the conveying chain 22 is not limited to 60°. It is preferable to set the V-angle formed by the conveying path of the conveying chain 22 to 55° to 65°, such as 55°, 58°, 63°, 65°, etc., which are all better choices.

[0043] Furthermore, in order to support and drive the conveyor chain 22, this embodiment has multiple sets of driven sprocket sets 25 on the frame 21. The multiple sets of driven sprocket sets 25 are respectively engaged and driven by multiple high and low transition points of the conveyor chain 22. With this arrangement, each turning point of the conveyor chain 22 can be supported by the driven sprocket sets 25, and it can also ensure that the conveyor chain 22 as a whole can be in a state of sufficient tension.

[0044] After adopting the above configuration, in order to drive the conveyor chain 22, this embodiment of the circulating drying conveyor mechanism 20 also includes a conveyor drive motor 26, and a main drive sprocket 271 and a secondary drive sprocket 272 that are meshed and connected to the conveyor chain 22. The conveyor drive motor 26 drives the main drive sprocket 271 to rotate through the belt 273. The main drive sprocket 271 is located within the space enclosed by the conveyor chain 22, that is, the main drive sprocket 271 opens the conveyor chain 22 from the inside out. The two secondary drive sprockets 272 are respectively placed on both sides of the conveyor chain 22. The secondary drive sprocket 272 on the left side presses the conveyor chain 22 from the outside in, and the secondary drive sprocket 272 on the right side is located within the space enclosed by the conveyor chain 22 and also opens the conveyor chain 22 from the inside out.

[0045] Furthermore, in order to avoid interference between pallets 23 during vertical transport transitions and thus affect transmission, the spacing between adjacent pallets 23 at the vertical transport transition points should be sufficiently large. Therefore, this embodiment is provided with multiple sets of driven sprocket groups 25, each including two driven sprockets 251. The two driven sprockets 251 are respectively engaged and connected to the upward transport section and the downward transport section of the conveyor chain 22. The two driven sprockets 251 are horizontally separated by an anti-interference distance 252, which is used to prevent interference between adjacent pallets 23 during vertical transport transitions.

[0046] The anti-interference distance 252 mentioned here should be determined according to the size of the tray 23. For example, if the tray 23 is large in shape and size, the anti-interference distance 252 can be increased appropriately, and if the tray 23 is small in shape and size, the anti-interference distance 252 can be reduced appropriately.

[0047] The aforementioned tray 23 is mainly used to place materials for drying. When the materials are conveyed to the circulating drying conveyor 20 by the lifting mechanism 10, the materials will be sent to the tray 23. Due to the cyclic rotation of the conveyor chain 22, the materials can move with the tray 23 to the drying conveyor area 241 for drying, and after drying, they will be sent to the unloading conveyor area 242 for unloading.

[0048] In this embodiment, the pallet 23 is flippable. For example, a corresponding pivot can be set on the conveyor chain 22 and a pin can pass through the top of the pallet 23 to achieve the flipping of the pallet 23. Therefore, when the pallet 23 moves to the return conveyor mechanism 30, the material on the pallet 23 can be poured into the return conveyor mechanism 30 by flipping the pallet 23 for subsequent conveying.

[0049] To control the pallet 23 to flip, either passive or active control methods can be used. For example, an obstruction can be set at the unloading position of the pallet 23, and when the pallet 23 moves past the obstruction, the two will abut against each other, thereby pushing the pallet 23 to flip and unload. Alternatively, the return conveying mechanism 30 can be equipped with a flipping structure 31, which is located in the unloading conveying area 242. The flipping structure 31 is used to control the flipping of the pallet 23, thereby sending the material to the return conveying mechanism 30 for conveying. For example, the flipping structure 31 can use a telescopic rod, cylinder, or other structure to push the pallet 23 to flip, which can also achieve the unloading operation.

[0050] Regarding the aforementioned return conveying mechanism 30, as Figure 1 As shown, the return conveying mechanism 30 is used to receive materials in the unloading conveying area 242 and send them back to the lifting mechanism 10. Therefore, the main function of the return conveying mechanism 30 is also to realize the conveying of materials. To achieve this purpose, various commonly used conveying devices, such as conveyor belts, can also be used.

[0051] Specifically, in this embodiment, the return conveying mechanism 30 includes a collection conveyor 32, a lifting conveyor 33, and a transfer conveyor 34. The collection conveyor 32 is used to collect the material unloaded from the pallet 23 and convey it to the lifting conveyor 33. The lifting conveyor 33 is arranged obliquely from bottom to top and is used to send the material to the transfer conveyor 34. The transfer conveyor 34 is used to send the material to the lifting mechanism 10 for conveying.

[0052] The collecting conveyor 32, the lifting conveyor 33, and the transfer conveyor 34 are all used to realize material transportation, so they can also be implemented by various commonly used transmission devices, such as conveyor belts. At this time, the material on the pallet 23 will first be unloaded onto the collecting conveyor 32, and then the collecting conveyor 32 will send the material to the lifting conveyor 33. The lifting conveyor 33 will then transfer the material to the transfer conveyor 34, and finally the transfer conveyor 34 will send the material to the lifting mechanism 10 for transportation, so as to dry it again.

[0053] The purpose of the above operation is to achieve material flipping. When the material is transferred from the pallet 23 to the collecting conveyor 32, the falling and collision of the material will inevitably cause its placement to change. Therefore, when it is transported back to the lifting mechanism 10 for subsequent transport, the material can be dried again in a new placement state. This not only eliminates the need to set up a complex material flipping structure, but also ensures that the material can get a full drying effect.

[0054] from Figure 1As shown in the direction, the lifting conveyor 33 here is used to transport materials from the lower right to the upper left, so the conveying direction of the lifting conveyor 33 is opposite to the conveying direction of the lifting mechanism 10. This setting has two functions: first, it can send the materials back to the lifting mechanism 10 with a small transmission distance; second, it can send the materials to the transfer conveyor 34 by falling, that is, to flip the materials again to ensure that the materials are fully flipped.

[0055] In addition, after the materials have finished drying, they need to be collected. Therefore, in order to improve the efficiency of material collection, such as... Figure 1 and Figure 2 As shown, in this embodiment, the transfer conveyor 34 is configured to control the forward and reverse rotation of its own drive motor to switch the conveying direction, and one of the conveying directions of the transfer conveyor motor points to the lifting mechanism 10.

[0056] For example, in this embodiment, the transfer conveyor 34 is a linear conveyor belt driven by a motor. When the motor rotates forward, the transfer conveyor 34 feeds material to the lifting mechanism 10 so that the material can be repeatedly dried. After the material is dried, the motor only needs to be controlled to rotate, and the transfer conveyor 34 can transport the collected material in the reverse direction. The staff can collect the material at the end of the reverse transport.

[0057] It should also be noted that multiple automatic drying devices may be used simultaneously in the same drying room 40, such as Figures 1 to 4 As shown, multiple automatic drying devices can be set up to share a single transfer conveyor 34. The transfer conveyor 34 is arranged along the unloading points of multiple lifting conveyors 33 and the receiving points of multiple lifting mechanisms 10, thereby improving the coordination of multiple automatic drying devices.

[0058] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
