Description

Technical Field

[0001] The present invention relates to the field of food processing, and particularly to a fully automatic fish jerky turning machine and a fish jerky drying method. Background Art

[0002] During the preparation of fish jerky, drying is required. The currently used low-temperature all-year fish jerky machine imitates natural drying conditions, and the drying temperature is controlled between 20°C and 30°C. Compared with the common dryers on the market with a drying temperature of 50°C to 60°C, the fish jerky made by the low-temperature all-year fish jerky machine has a better taste. The structure of the low-temperature all-year fish jerky machine is as Figure 1 shown, including a library body 1. On one side in the width direction of the library body 1, a drying chamber 2 is arranged, and on the other side in the width direction, a heat pump main unit 3 and control devices are arranged. The dimension in the depth direction of the drying chamber 2 is the largest. Multiple groups of material racks 4 are arranged at intervals up and down in the drying chamber 2, and the net trays for supporting the fish slices are installed on the material racks 4 in a pull-out manner. The deficiencies of this prior art are as follows: The drying effect of the lower surface of the fish slices in contact with the net trays is affected, and uneven drying is likely to occur. Therefore, the operator needs to repeatedly turn the fish slices, and when collecting samples, the net trays also need to be pulled out one by one and the dried fish slices are taken out and collected with clips. Both manual turning and manual sample collection will take a lot of time for the operator.

[0003] There are some devices in the prior art that can automatically turn fish jerky. There are two common problems: First, to meet the need for turning, the fish jerky is clamped by upper and lower layers of net trays to prevent the fish jerky from falling during the turning process; Second, to meet the rotation requirement of the net trays, enough distance needs to be left between adjacent layers of net trays, which will greatly reduce the number of net trays that can be set in the drying cavity and greatly reduce the single drying capacity of the dryer. When using double-layer net trays, both the upper and lower surfaces of the fish jerky will contact the corresponding net trays or be extremely close to the net trays. The non-hollow parts on the net trays will affect the dispersion of moisture in the fish jerky, thereby prolonging the drying time required for the fish jerky, increasing energy consumption, and also making the humidity of different parts of the fish jerky different, which will affect the taste of the made fish jerky. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic fish jerky dryer to solve the technical problems of small capacity, poor drying effect, and high energy consumption existing in the automatic fish jerky dryers in the prior art; the purpose of the present invention is also to provide a method for drying fish jerky using the above-mentioned fully automatic fish jerky turning machine.

[0005] To achieve the above purpose, a fully automatic fish jerky turning machine of the present invention adopts the following technical solutions:

[0006] A fully automatic fish-drying machine with turnover function, comprising a library body, a drying chamber is arranged in the library body, and multiple groups of mesh trays are arranged at intervals up and down in the drying chamber. Guide members and rotating disks are symmetrically arranged on both sides of the library body. The guide members have two parts and are respectively arranged above and below the rotating disk.

[0007] The mesh tray includes a fixed mesh tray fixed in the rotating disk and a movable mesh tray installed in the guide member.

[0008] Corresponding guide grooves I and II are opened on the guide member and the rotating disk for guiding the movable mesh tray to move in the up and down direction.

[0009] A driving mechanism for driving the movable mesh tray to approach or move away from the fixed mesh tray is arranged in the library body. The driving mechanism includes a first driving part with a linear displacement output end, and also includes sliders that can be guided and slid in the up and down direction. There are two groups of sliders arranged up and down and corresponding to the position of the guide member. The driving end is used to drive the sliders to move. Multiple groups of telescopic rods are arranged in the sliders. The number of telescopic rods is the same as the number of movable mesh trays on the corresponding guide member to extend and push the movable mesh tray or retract to disengage from the movable mesh tray.

[0010] A mesh tray supporting mechanism for fixing the mesh tray that has moved into place is also arranged in the drying chamber.

[0011] An axial displacement locking mechanism for the movable mesh tray and a second driving part are also arranged in the library body. The axial displacement locking mechanism for the movable mesh tray is used to limit the axial displacement of the mesh tray after it is closed. The second driving part is used to drive the rotating disk to rotate to drive all the closed mesh trays to rotate together.

[0012] Furthermore, the guide member includes an upper guide member and a lower guide member. The upper guide member and the lower guide member are symmetrically arranged on both sides of the rotating disk, and the number of movable mesh trays arranged in the upper guide member and the lower guide member is the same.

[0013] Furthermore, the driving mechanism also includes a first connecting rod, a second connecting rod and a chute. The chute is fixed in the library body. The linear displacement output end of the first driving part, the first connecting rod, the second connecting rod and the middle part of the slider are sequentially hinged. There are two groups of connecting rod mechanisms composed of the first connecting rod, the second connecting rod and the slider. Both groups of connecting rod mechanisms are driven by the same first driving part to drive the two sliders to open and close simultaneously.

[0014] Further, a positioning groove communicating with the first guiding groove is provided on the guiding member; the movable mesh plate includes a mesh frame and a mesh surface, and further includes positioning shafts located on both sides of the mesh frame. The cross-sectional shape of the positioning shaft matches the shape of the first guiding groove. The supporting mechanism includes a positioning plate rotatably installed in the positioning groove, and further includes a positioning plate rotation mechanism for driving the rotation of the positioning plate. Under the action of the positioning plate rotation mechanism, the free end of the positioning plate can be rotated into the first guiding groove to support the corresponding movable mesh plate, or can be rotated out of the first guiding groove to enable the corresponding movable mesh plate to move along the first guiding groove.

[0015] Further, a flower-shaped assembly groove is formed in the middle of the positioning plate. The positioning plate rotation mechanism includes a rotating rod extending vertically, a positioning plate rotation driving motor for driving the rotation of the rotating rod, and a rotating rod translation driving motor for driving the up-and-down translation of the rotating rod. A plurality of assembly protrusions that are rotationally locked with the assembly groove are provided on the rotating rod. A through groove that matches the shape of the assembly groove is formed on the guiding member. There are two groups of the assembly protrusions. The first group of assembly protrusions are arranged at equal intervals to drive the rotation of all the positioning plates simultaneously. The distance between adjacent two groups in the second group of assembly protrusions increases from near to far to drive the separate rotation of a certain positioning plate at a certain moment.

[0016] Further, two groups of movable mesh plate locking mechanisms are provided, which are respectively arranged at the upper and lower ends of the rotating disc, and include locking rods and locking holes arranged on both sides of the second guiding groove. The locking rods are telescopically installed on the rotating disc, and the sizes and positions of the locking rods and the locking holes match.

[0017] Further, a control system is also installed in the library body. The control system includes a controller, a first infrared sensor, a timer, a first pressure sensor, a second infrared sensor, a second pressure sensor, and a third infrared sensor. The timer, the first infrared sensor, the second infrared sensor, the third infrared sensor, the first pressure sensor, and the second pressure sensor are electrically connected to different input ends of the controller. The telescopic rod, the first driving part, the second driving part, the positioning plate rotation driving motor, and the rotating rod translation driving motor are electrically connected to different output ends of the controller to be controlled to move according to the position of a movable mesh plate with a certain number and the opening and closing state of the positioning plate. The first pressure sensor is installed on the mesh frame of the movable mesh plate to detect whether it is closed in place. The first infrared sensor is used to detect the opening and closing state of the positioning plate. The second pressure sensor is installed at the bottom of the locking hole to detect whether the locking rod is locked in place. The second infrared sensor is installed between the locking rod and the rotating disc to detect whether the locking rod is fully retracted. The third infrared sensor is used to detect whether the movable mesh plate is opened in place.

[0018] Furthermore, the positioning plate includes an overhanging end, and the length of the positioning plate on the movable network disk gradually decreases from the inside to the outside. The receiving end / transmitting end of the infrared sensor is installed on the part of the overhanging end extending out from the adjacent overhanging end.

[0019] Furthermore, a locking hole is provided on the rotating disk at a position staggered from the second guide groove, and an electric latch which can be inserted into and detached from the locking hole is installed in the storage body.

[0020] The dried fish drying method of the present invention adopts the following technical solutions:

[0021] Step 1: After the timer countdown is reached, the telescopic rods on the upper and lower sliders are extended and push the corresponding movable network disk to continue to move upward for a distance so that the corresponding movable network disk leaves the positioning plate. Then, the rotating rod translation drive motor is controlled to push the first set of assembly protrusions in the rotating rod inward to insert into all the positioning plates. Then, the positioning plate rotation drive motor is controlled to rotate 90 degrees clockwise to rotate the positioning plate out of the guide slot.

[0022] Step 2: The first drive unit extends, driving the upper and lower movable network disks to close synchronously toward the middle. When the detection pressure of a certain numbered pressure sensor 1 reaches the set value, the corresponding numbered telescopic rod is retracted. After all the movable network disks are closed in place, the controller controls the locking rod to extend. When the detection pressure of the pressure sensor 2 reaches the set value, the controller controls the second drive unit to rotate to achieve flipping. After the flipping is completed, the network disks are renumbered, and the order of the renumbering is reversed from the original numbering order.

[0023] Step 3: The controller controls the locking rod to retract. When the infrared sensor 2 detects that the locking rod is fully retracted, the telescopic rod corresponding to the proximal movable network disk in the upper guide is controlled to extend, and the telescopic rod corresponding to the distal movable network disk in the lower guide is controlled to extend to support the corresponding movable network disk group. Then the controller controls the first driving part to extend and drive the movable network disk to open to both sides; according to the detection result of the infrared sensor 1, the first driving part is paused, and the translation movement drive motor of the control rod is controlled to move upward to the corresponding assembly protrusion in the second group of assembly protrusions and the corresponding positioning plate to rotate and cooperate, and then the positioning plate rotation drive motor is controlled to rotate counterclockwise 90 degrees to make the positioning plate rotate into the guide groove 1, retract the corresponding telescopic rod so that the movable network disk is supported by the positioning plate, and then the first driving part is controlled to move so that the position of the upper telescopic rod is aligned with the upper movable network disk, so that the telescopic rod is extended to push the second group of movable network disks to open, until all the movable network disks are opened to the right.

[0024] Compared with the prior art, the present invention provides a fully automatic fish drying machine with the following advantages:

[0025] After the countdown ends, both the upper movable net tray and the lower movable net tray will move towards the fixed net tray in the middle. After all the net trays are locked by the movable net tray locking mechanism, the second driving part drives the rotating disk and all the net trays therein to rotate together, realizing the synchronous turning of all the dried fish. The whole process does not require manual assistance, and after turning, the distance between the upper surface of the dried fish and the net surface remains normal. The moisture in the dried fish can quickly dissipate through the upper surface, shortening the drying time required for the dried fish, reducing energy consumption, and also ensuring that the humidity of each part in the dried fish is uniform and has a good taste.

[0026] Furthermore, after closing, the net frames of each net tray are in contact with each other. The thickness of the net frame is greater than the thickness of the fish to be dried. The closed net frame will not produce indentations on the fish and can also prevent the fish from slipping out of the net frame during the turning process.

[0027] The parts not involved in this device are the same as those in the prior art or can be implemented using the prior art. The structure of the present invention is scientific and reasonable, safe and convenient to use, and provides great help to people. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] An embodiment of a fully automatic fish jerky turning machine of the present invention:

[0042] A fully automatic fish jerky turning machine, the structure of which is as Figures 2 to 9 shown, includes a storage body 1, a drying chamber 1-1 is provided in the storage body 1, and a storage door 2 is movably installed at the front end of the storage body 1. Guiding members 3 and rotating disks 4 are symmetrically installed on the left and right side walls of the drying chamber 1-1, and a plurality of groups of mesh disks 5 with upper openings are arranged at intervals in the up and down direction in the drying chamber 1-1. A driving mechanism 6 and a control system 7 are also provided in the storage body 1. During the use of the present invention, the control system 7 causes each group of mesh disks 5 to retract towards the middle at regular intervals, and after retraction, the whole is turned over, and after the turning is completed, it can automatically open to perform the next round of drying.

[0043] On the library body 1, two upper and lower groups of guiding members 3 are provided on each side of the drying chamber 1-1, and the two upper and lower groups of guiding members 3 are symmetrical. The rotating disk 4 is located between the upper and lower groups of guiding members 3. A corresponding guiding groove one 31 and guiding groove two 41 are provided between the rotating disk 4 and the guiding member 3. A positioning groove 32 communicating with the guiding groove one 31 is also provided on the guiding member 3, and the positioning grooves 32 on the upper guiding member and the lower guiding member are symmetrical up and down. A group of mesh trays 5 (this mesh tray is a fixed mesh tray 51) are fixed in the mounting hole 42 in the middle of the rotating disk 4. Multiple groups of mesh trays 5 (this mesh tray is a movable mesh tray 52) are installed on the upper and lower guiding members 3. Device chambers are provided on the left and right sides of the drying chamber on the library body 1, and a set of driving mechanisms 6 are installed in each device chamber to push the movable mesh trays 52 to move from both sides. A long and narrow slit 13 communicating with the device chamber 12 and the drying chamber 1-1 is provided on the library body 1.

[0044] The control system 7 includes a controller 71, an infrared sensor one 72, a timer 73, a pressure sensor one 74, a pressure sensor two 75, an infrared sensor two 76, and an infrared sensor three 77. The timer 73 is connected to an input end of the controller 71 to send a turning-over instruction to the controller 71 regularly.

[0045] The driving mechanism 6 is used to drive the movable mesh trays 52 installed in the upper guiding member 3 and the movable mesh trays 52 installed in the lower guiding member 3 to approach or move away from the fixed mesh tray 51 synchronously. The two ends of the rotating disk 4 are fixed with movable mesh tray locking mechanisms 8. The movable mesh tray locking mechanisms 8 are used to prevent the folded movable mesh trays 52 from opening under the action of gravity. The rotating disk 4 is used to drive all the folded mesh trays 5 to rotate together to achieve turning over. After turning over, the movable mesh trays 52 are opened to increase the distance between the upper surface of the fish fillet and the mesh tray, avoiding the too-close distance between the upper surface of the fish fillet and the mesh tray and affecting the hot air flow to carry away the moisture in the fish fillet.

[0046] The mesh tray 5 includes a mesh frame 53 and a mesh surface 54. Positioning shafts 55 matching the sizes of the guiding groove one 31 and the guiding groove two 41 are installed on the left and right sides of the mesh frame 53. The distance between the upper end of the mesh frame 53 and the mesh surface 54 is slightly larger than the thickness of the fish to be dried, and the sizes of the mesh frames 53 of all the mesh trays 5 are the same. Therefore, after multiple groups of mesh trays 5 are folded, the upper mesh frame 53 will press on the lower mesh frame 54, and the upper mesh surface 54 will not contact the fish meat on the lower mesh surface 54, and the finished product quality will not be damaged. The positioning shaft 55 can guide and move in the guiding groove one 31 and the guiding groove two 41.

[0047] There are six groups of pressure sensors one 74, namely 74(1), 74(2), 74(3), 74(4), 74(5), and 74(6), which are respectively installed at the lower ends of the mesh frames 53 of the three upper groups of movable mesh trays 5 and the upper ends of the mesh frames 53 of the three lower groups of movable mesh trays 5. When the mesh trays 5 are folded together, the pressure sensor one 74 will be squeezed.

[0048] The network disk support mechanism 11 includes a positioning plate 11-1 and a positioning plate rotating mechanism for driving the rotation of the positioning plate. The positioning plate 11-1 is rotatably mounted on the lower wall surface of the positioning groove 32, and a flower-shaped assembly groove 11-2 is provided in the middle of the positioning plate 11-1. The positioning plate rotating mechanism includes a rotating rod 11-3 extending vertically, a positioning plate rotation driving motor 11-4 for driving the rotation of the rotating rod 11-3, and a rotating rod translation driving motor 11-5 for driving the up and down translation of the rotating rod 11-3. A plurality of assembly protrusions 11-6 that are rotationally locked with the assembly groove 11-2 are provided on the rotating rod 11-3, and a through groove that matches the shape of the assembly groove 11-2 is provided on the guide member 3. There are two groups of assembly protrusions 11-6. The first group of assembly protrusions 11-6 (see the three positions pointed to by 11-6 on the left side in Figure 5 the figure) are arranged at equal intervals to drive the rotation of all the positioning plates 11-1 simultaneously. The distance between adjacent two groups of assembly protrusions 11-6 in the second group of assembly protrusions 11-6 (see the three positions pointed to by 11-6 on the right side in Figure 5 the figure) increases from near to far to drive the rotation of a certain positioning plate 11-1 alone at a certain moment.

[0049] An infrared sensor 72 is installed on the positioning plate 11-1. The emitting end of the infrared sensor 72 is arranged in the first guide groove 31, and the receiving end is arranged at the overhanging end of the positioning plate 11-1. The position of the emitting end corresponds to the position of the overhanging end when the positioning plate 11-1 is completely rotated into the first guide groove 31. Therefore, when the positioning plate 11-1 is completely rotated away, the photoelectric signal emitted by the emitting end is received by the positioning plate 11-1, and the signal detected by the infrared sensor 72 changes. When it is necessary to close the movable network disk 52, first control the driving mechanism 6 to push the positioning plate 11-1 away from the positioning plate 11-1, then control the rotating rod translation driving motor 11-5 to insert the first group of assembly protrusions 11-6 into all the positioning plates 11-1 at the same time, and control the positioning plate rotation driving motor 11-4 to drive all the positioning plates 11-1 to rotate clockwise by 90 degrees, so that they can be completely separated from the first guide groove. At this time, the movable network disk 52 can slide along the guide groove 31 to close. There are six groups of infrared sensors 72 corresponding to each other, which are 72(1), 72(2), 72(3), 72(4), 72(5), and 72(6).

[0050] The third infrared sensor 77 is installed on both sides of the first guiding groove 31 and its position corresponds to that of the positioning groove 32. When the positioning shaft 55 of the movable web plate 52 moves into place, the signal detected by the third infrared sensor 77 will change. From near to far, the length of the positioning shaft 55 in the movable web plate 52 gradually increases, and the installation position of the third infrared sensor 77 is on the part where the positioning shaft 55 exceeds the adjacent positioning shaft 55, so as to ensure that the third infrared sensor 77 can accurately identify whether the corresponding movable web plate 52 has moved into place. Six groups of the third infrared sensors 77 are correspondingly set, namely 77(1), 77(2), 77(3), 77(4), 77(5), and 77(6).

[0051] The sizes of the positioning plates 11-1 in different movable web plates 52 are different. Specifically, the closer the positioning plate 11-1 is to the fixed web plate 51, the larger its length is, and the receiving end is installed on the part where the positioning plate 11-1 exceeds the adjacent positioning plate 11-1. Therefore, when the movable web plates 5 are pushed upward and opened together, the distal movable web plate 52 will not trigger the first infrared sensor 72 below it during the upward movement, thus achieving the effect that each layer of the first infrared sensor 72 can only identify the movable web plate 52 of its own layer.

[0052] The driving mechanism 6 includes a first connecting rod 61, a second connecting rod 62, an electric push rod 63 (i.e., the first driving part), a slider 64, and a chute 65. The chute 65 extends vertically and is fixed in the library body 1, and the slider 64 is installed therein in a guiding and movable manner. The linear displacement output end of the electric push rod 63 extends horizontally. One end of the first connecting rod 61 is hinged to the linear displacement output end of the electric push rod 63, and the other end is hinged to the second connecting rod 62. The other end of the second connecting rod 62 is hinged to the middle of the slider 64. When the electric push rod 63 reciprocates, it can drive the slider 64 to move up and down in the chute 65 in a guiding manner. Two groups of link mechanisms composed of the first connecting rod 61, the second connecting rod 62, and the slider 64 are provided, and the two groups of link mechanisms are driven by the same electric push rod 63 to realize synchronous opening and closing.

[0053] In this embodiment, three groups of movable web plates 52 are installed in the upper and lower guiding members 3 respectively. Three telescopic rods 66 are arranged on each slider 64 at intervals up and down, and the distance between two adjacent telescopic rods 66 is the same as the distance between the corresponding two layers of web plates 5 in the open state. The upper end surface of the telescopic rod 66 is a plane, and it can pass through the narrow slit 13 and extend below the positioning shaft 55 to drive the positioning shaft 55 to move up and down. The structure for driving the telescopic rod 66 to move linearly in a telescopic manner can be a gear-rack mechanism, a worm and worm gear mechanism, or a ball screw and nut pair, which will not be introduced in detail in this application. The small motor for providing the telescopic power is installed in the slider 64, and the small motor is electrically connected to an output port of the controller 71 to be controlled to rotate forward and backward.

[0054] The movable web locking mechanism 8 includes locking rods 81 and locking holes 82 arranged on both sides of the second guide groove 41. When the locking rods 81 are inserted into the locking holes 82, they can press the positioning shafts 55 of the two most distal movable webs 5 to prevent the lower movable web 52 from opening under the action of gravity.

[0055] The second pressure sensor 75 is installed at the bottom of the locking hole 82. Therefore, after the locking rod 81 extends in place, it will apply force to the second pressure sensor 75, causing a change in its detection signal. The second infrared sensor 76 is installed on the rotating disk 4, and its installation position is close to the installation end of the locking rod 81. The transmitting end and the receiving end of the second infrared sensor 76 are located on different sides of the locking rods 81 on different sides. Therefore, after the locking rod 81 changes from the extended state to the fully retracted state, the detection signal of the second infrared sensor 76 will change. There are two groups of the second pressure sensor 75 and the second infrared sensor 76, namely 75(1), 75(2) and 76(1), 76(2), which are installed in the movable web locking mechanism 8 at different ends of the rotating disk 4.

[0056] In this embodiment, the locking rod 81 is completely embedded in the rotating disk 4 to prevent it from being knocked when rotating with the rotating disk 4. Limited by the size of the rotating disk 4, the locking rod 81 is a multi-section electric push rod. Therefore, it can be completely retracted behind the rotating disk 4 and can enter the locking hole 82 on the front side of the rotating disk 4 when fully extended.

[0057] A rotating motor 9 (i.e., the second driving part) for driving the rotation of the rotating disk 4 is installed in the library body 1. The function of the rotating motor 9 is to drive the rotating disk 4 to rotate after the movable webs 52 are closed towards the middle, so as to realize the simultaneous turning over of all the webs 5.

[0058] During use, the dried fish are placed on each layer of the webs except the topmost web 5 in sequence. After the drying set time, the driving mechanism 6 drives the movable web 5 to move towards the fixed web 51. After all the webs 5 are retracted, the movable web locking mechanism 8 locks all the webs 5 together. Then, the driving mechanism 6 drives the rotating disk 4 to rotate 180 degrees to complete the synchronous turning over of all the dried fish. After that, the driving mechanism 6 drives the movable web 5 to open to the set position, and the dried fish can be turned face up for uniform drying.

[0059] The process of automatic turning over of the webs of the present invention is as follows:

[0060] step1: When the countdown time of the timer 73 reaches, the telescopic rods 66 on the slider 64 all extend and push the corresponding movable web 5 to move upward a certain distance to make it leave the positioning plate 11-1. Then, control the translational motion driving motor 11-5 of the rotating rod to push the first set of assembly protrusions 11-6 in the rotating rod into all the positioning plates 11-1. Then, control the positioning plate rotation driving motor 11-4 to rotate clockwise by 90 degrees to make the positioning plate rotate out of the first guide groove 31.

[0061] Step 2: The electric push rod 63 extends, driving the upper movable web plate 5 and the lower movable web plate 5 to close towards the middle synchronously. When closing towards the middle, the proximal movable web plate 5 first contacts the fixed web plate 51. When the detected pressure of a pressure sensor 1 - 74 with a certain number reaches the set value, it proves that the corresponding numbered movable web plate 52 has been closed in place, and the telescopic rod 66 with the corresponding number is retracted. After all the movable web plates 52 are closed in place, the controller 71 controls the locking rod 81 to extend. When the detected pressure of the pressure sensor 2 - 75 in the lock hole 82 reaches the set value, it proves that the locking rod 81 is fully inserted into the lock hole 82, and at this time, the telescopic rods 66 have also been fully retracted. The controller 71 sends an instruction to the rotation motor 9 to drive the rotation motor 9 to rotate, and all the web plates 5 can be turned over simultaneously. After turning over, the web plates are re - numbered, and the order during re - numbering is reverse to the original numbering order to ensure that the movable web plates 5 after turning over can still correspond to the fixed web plates one by one.

[0062] Step 3: After all are turned over, the controller 71 controls the locking rod 81 to retract. When the infrared sensor 2 - 76 installed on the rotating disk 4 detects that the locking rod 81 is fully retracted, the telescopic rod 66 corresponding to the proximal movable web plate 5 in the upper guide member 3 first extends to support the upper movable web plate 5, and the telescopic rod 66 corresponding to the distal movable web plate 5 in the lower guide member 3 first extends to support the lower movable web plate 5. Then the controller 71 controls the electric push rod 63 to extend to drive the movable web plate 5 to open to both sides.

[0063] Step 3 specifically includes the following steps:

[0064] When the infrared sensor 3 - 77 detects that the nearest movable web plate 5 has moved in place, control the translation motion driving motor 11 - 5 of the rotating rod to move upward until the second - group assembly protrusion 11 - 6 only has a non - rotating fit with the positioning plate 11 - 1 of this number, and control the positioning plate rotation driving motor 11 - 4 to rotate counter - clockwise by 90 degrees so that the positioning plate 11 - 1 of this number is re - inserted into the first guide groove 31 to support the movable web plate 5. During this process, the section of the rotating rod 11 - 3 where it cooperates with other positioning plates 11 - 1 is a smooth shaft section, so it will only drive the positioning plate 11 - 1 of this number to rotate, and other numbered positioning plates 11 - 1 can maintain their original states.

[0065] Then control the electric push rod 63 to continue to extend a certain distance. When the position of the lowermost telescopic rod 66 in the upper slider 64 corresponds to the position of the upper movable web plate 52 in the upper guide member 3, this telescopic rod 66 extends a second time under the upper movable web plate 52. During this process, the lowermost telescopic rod 66 in the lower slider 64 always supports the two groups of lower movable web plates 52 to move downward and open. The process of the corresponding positioning plate 11 - 1 opening to support the movable web plate 52 is the same as the above and will not be elaborated further.

[0066] During the opening process, for the upper movable storage tray 52, the aim is to control the movement of the telescopic rod 66 that is located below the upper slider 64 and has the closest distance to it. By the time all the movable storage trays 5 are fully opened, the telescopic rods 66 have all retracted.

[0067] In other embodiments, after all the movable storage trays 5 are fully opened, the timing of the timer 73 can also be reset.

[0068] Embodiment 2:

[0069] The difference between Embodiment 2 and Embodiment 1 is that: to prevent the rotating disk 4 from rotating uncontrollably, a locking hole extending vertically is formed on the rotating disk 4, and the locking hole is adapted to receive the rotating rod 11-3 for insertion.

[0070] Embodiment 3:

[0071] The difference between Embodiment 3 and Embodiment ② is that: when the rotating rod 11-3 is in the extreme position, it does not contact the rotating disk 4. To prevent the rotating disk 4 from rotating uncontrollably, the locking hole extends horizontally and is offset from the second guiding groove 41, and an electric plug lock that can be inserted into and disengaged from the locking hole 42 is installed in the library body 1.

[0072] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
