Technical Field
[0001] This invention relates to a metal processing equipment, and more particularly to an integrated equipment for annealing and storing aluminum alloy plates. Background Technology
[0002] In metal manufacturing, aluminum alloy sheets are a common type of metal processing equipment. Documentation is used to collect and process data, preventing clutter. However, in companies with many employees, the number of employee files can become substantial. These files need to be categorized and stored. Typically, these categorized files are placed in one area, which can lead to difficulties in retrieving and archiving them. This can cause confusion during document retrieval. Therefore, it is necessary to develop a device for retrieving and archiving aluminum alloy sheets. Summary of the Invention
[0003] To address the technical deficiencies in the background art, this invention proposes an integrated device for annealing and storing aluminum alloy plates, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:
[0004] An integrated annealing and storage device for aluminum alloy plates includes: an upper box, a lower box, a storage box, a movable housing, an inlet groove, and a storage groove. The upper box is located above the lower box. The storage box is connected to the back of the upper box. The front of the upper box has an outlet. Movable grooves are respectively formed on two sides between the front and back of the upper box. The openings of the two movable grooves of the upper box face downwards and are connected to the upper edge of the lower box. A movable housing is respectively installed in each of the two movable grooves of the upper box. Each movable housing reciprocates along an opposite movable groove, and each movable housing is clamped by the lower box. A cavity is formed between the upper box and the lower box. The storage box is connected to the cavity between the upper box and the lower box. The two movable housings are connected by a guide groove, which moves back and forth along two movable grooves. Several storage slots are vertically arranged inside the lower housing, with their upper ends arranged in a straight line and aligned with the lower opening of the inclined section of the guide groove. The guide groove is composed of a horizontal section and an inclined section. The horizontal section passes through the storage housing, and the end of the inclined section connected to the horizontal section is arranged in a downward-curving arc. The inclined section is inclined towards the front of the upper housing along the curvature of the arc section. Several storage slots face the front of the upper housing and are stacked sequentially. The opening of each storage slot faces upward, and each storage slot opening has a top plate.
[0005] A connecting plate is provided at the upper edge of the outlet on the front of the upper box. A baffle is connected horizontally below the connecting plate by a pin. The baffle swings in a fan shape with the pin as the axis. There is a through-hole at the rear of the upper box. The edge of the through-hole of the upper box is connected to the inside of the storage box.
[0006] The lower housing contains a control unit at the rear; a limiting groove is provided on each of the opposite sides of the lower housing; a control panel is provided on the front of the lower housing, and a conduit connects the control panel to the control unit, and they are electrically connected.
[0007] The guide groove is closely attached to both sides of the lower housing, and each side has a protrusion. The two protrusions of the guide groove are respectively embedded in each corresponding limiting groove. An opening is opened above the horizontal section of the guide groove, and a glass plate is inlaid therein. An upwardly convex arc surface is provided above the bottom of the horizontal section. An opening is provided on the surface of the arc surface of the horizontal section, and a guide roller is embedded in the opening. The guide roller provided in the horizontal section is fixed to a guide motor. A slot is opened above the arc section of the guide groove, and a lever is embedded in the slot. The lever is consistent with the upper curved surface of the arc section of the guide groove. A rotating shaft runs horizontally through the lower end of the lever. One end of the rotating shaft of the lever passes through the guide groove, and the other end of the lever extends to the outside of the guide groove and is connected to a swing motor. The horizontal section and A channel is formed within the inclined section. A vertical plate is provided at the end of the horizontal section away from the inclined section, and the downward-facing end of the inclined section is open. At the lower opening of the inclined section, and on opposite sides of the channel, there are two guide wheels, each connected to a drive motor. At least two positioning contact pieces are provided at the lower opening of the inclined section, and at the edge that is in contact with the upper opening of several storage slots. A conduit is connected to the side of the two positioning contact pieces away from the upper side of the several storage slots. The two positioning contact pieces are connected to the corresponding drive motors via conduits. A pressing member is provided on the side of the inclined section facing the front of the upper housing. The end of the pressing member away from the inclined section abuts against the lower housing. The pressing member is electrically connected to the output motor and the swing motor via conduits.
[0008] Each of the storage slots is provided with a battery valve below it and a magnetic post above it. The magnetic post passes through each of the storage slots. The top plate inside the storage slot is connected to the top of the magnetic post. The top plate moves back and forth along the slot opening of each storage slot through the interaction between the magnetic post and the battery valve. Several of the battery valves are respectively connected to the control unit by conduits.
[0009] The width of the storage box is the same as the width of the inlet groove; a viewing glass is embedded on the top of the storage box; a top block is provided inside the storage box, and one side of the top block is attached to the end of the horizontal section of the inlet groove.
[0010] The beneficial effects of this invention are as follows:
[0011] In the above structure, the aluminum alloy plate placed vertically in the storage slot is automatically selected, pulled out, and its position adjusted and stored by the reciprocating guide groove.
[0012] When aluminum alloy sheets need to be stored, the inlet slot is moved by the movable housings on both sides to the outlet of the upper housing. At this time, the levers on the upper surface of the inlet slot swing downwards, and the upper ends of the levers overlap with the lower surface of the inlet slot, so that the inlet slot is only set as a horizontal section, preventing the opening leading to the inclined section from leaking out and causing the aluminum alloy sheet to fall during placement. After the aluminum alloy sheet is placed through the outlet, the inlet slot moves in one direction by the movable housings on both sides. After the inclined section of the inlet slot reaches the position where the aluminum alloy sheet is placed, the levers of the inlet slot lift upwards, connecting the inclined section with the horizontal section, allowing the aluminum alloy sheet to slide down the inclined section and into the corresponding storage slot for storage.
[0013] When the aluminum alloy plate needs to be removed, the two movable boxes move to the top of the corresponding storage slot. At this time, the top plate of the storage slot is lifted up, and the aluminum alloy plate is guided into the opening below the inclined section. Then, the aluminum alloy plate is guided into the horizontal section by the guiding device in the inclined section. In this case, the horizontal section of the guiding slot can be moved to the storage box, and the document can be inspected through the storage box, reducing the number of steps to remove the plate. Furthermore, the aluminum alloy plate can be exported outward by moving the horizontal section to the outlet and the guiding structure inside the horizontal section. Attached Figure Description

[0019] The embodiments of the present invention will be described below with reference to the accompanying drawings and related examples. The embodiments of the present invention are not limited to the following examples, and the present invention relates to the relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.
[0020] like Figures 1 to 5 As shown, an integrated annealing and storage device for aluminum alloy plates includes: an upper box 1, a lower box 2, a storage box 3, a movable housing 4, an inlet groove 5, and a storage groove 6. The upper box 1 is located above the lower box 2. The storage box 3 is connected to the back of the upper box 1. The front of the upper box 1 has an outlet 11. Movable grooves are respectively opened on the two sides between the front and back of the upper box 1. The openings of the two movable grooves of the upper box 1 face downward and are connected to the upper edge of the lower box 2. A movable housing 4 is respectively installed in the two movable grooves of the upper box 1. Each movable housing 4 moves back and forth along an opposite movable groove, and each movable housing 4 is clamped by the lower box 2. A cavity is formed between the upper box 1 and the lower box 2. The storage box 3 is connected to the cavity between the upper box 1 and the lower box 2. Next, an inlet groove 5 is fixedly connected between the two mobile housings 4. The inlet groove 5 moves back and forth along the two mobile housings 4. Several storage grooves 6 are vertically arranged inside the lower housing 2. The upper part of the several storage grooves 6 are arranged in a straight line and fits against the lower opening of the inclined section 52 of the inlet groove 5. The inlet groove 5 is composed of a horizontal section 51 and an inclined section 52. The horizontal section 51 passes through the storage housing 3. The end of the inclined section 52 connected to the horizontal section 51 is arranged in a downward arc shape. The inclined section 52 is inclined towards the front of the upper housing 1 along the curvature of the arc section. Several storage grooves 6 face the front of the upper housing 1 and are stacked in sequence. The opening of each storage groove 6 faces upward and a top plate 61 is provided in the opening of each storage groove 6.
[0021] In the above structure, the aluminum alloy plate placed vertically in the storage slot 6 is automatically selected, pulled out, and its placement and storage are adjusted by the reciprocating guide slot 5.
[0022] When it is necessary to store the aluminum alloy plate, the inlet groove 5 is moved by the movable housing 4 on both sides and moved to the outlet 11 of the upper housing 1. At this time, the lever 54 starting from the upper surface of the inlet groove 5 swings downward and the upper end of the lever 54 overlaps with the lower surface inside the inlet groove 5, so that the inlet groove 5 is only set as the horizontal section 51, preventing the opening leading to the inclined section 52 from leaking out and causing the aluminum alloy plate to fall during placement. After the aluminum alloy plate is put into the outlet 11, the inlet groove 5 moves in one direction by the movable housing 4 on both sides. After the inclined section 52 of the inlet groove 5 reaches the position where the aluminum alloy plate is placed, the lever 54 of the inlet groove 5 is lifted upward, so that the inclined section 52 connects with the middle of the horizontal section 51, and the aluminum alloy plate slides down the inclined section 52 and arrives at the corresponding storage groove 6 for storage.
[0023] When it is necessary to remove the aluminum alloy plate, the two movable housings 4 move to the top of the corresponding storage slot 6. At this time, the top plate 61 of the storage slot 6 is lifted up, and the aluminum alloy plate is guided into the opening below the inclined section 52. Then, the aluminum alloy plate is guided to the horizontal section 51 through the guiding device in the inclined section 52. In this case, the horizontal section 51 of the guiding slot 5 can be moved to the storage box 3, and the document can be inspected through the storage box 3, reducing the number of steps to remove the plate. Furthermore, the aluminum alloy plate can be guided outward through the guide structure inside the horizontal section 51 by moving the horizontal section 51 to the outlet 11.
[0024] With the above structure, it should be further explained that the upper opening of the arc-shaped section of the inlet groove 5 is higher than the opening of the outlet 11. Therefore, when the aluminum alloy plate is discharged through the transverse section 51, the outlet 11 can be prevented from obstructing the aluminum alloy plate.
[0025] Furthermore, in order to further reduce the contamination of the cavity by external dust and other dirt, a folding cover 41 is horizontally embedded in each of the two moving slots. The folding cover 41 is folded in the front and back direction. The edge of each folding cover 41 is fixed to the corresponding moving housing 4, and the other edge of the folding cover 41 is fixedly connected to the vertical side of the corresponding moving slot.
[0026] In order to ensure that each mobile housing 4 can move along the limited position of the moving slot, a gear protrudes from the bottom of each mobile housing 4, and a toothed groove is opened at the upper edge of the lower housing 2 corresponding to the gear. Each mobile housing 4 moves back and forth in the corresponding toothed groove by rotating the gear, so that each mobile housing 4 can move back and forth in the moving slot.
[0027] A connecting plate is provided at the upper edge of the outlet 11 on the front of the upper box 1. A baffle 12 is connected horizontally below the connecting plate by a pin. The baffle 12 swings in a fan shape with the pin as the axis. There is an insertion port at the rear of the upper box 1. The edge of the insertion port of the upper box 1 is connected to the inside of the storage box 3.
[0028] With the above structure, it should be further explained that the baffle 12 is set to block external dust and dirt. The baffle 12 is connected to the connecting plate by a pin, and the lower part of the baffle 12 can be opened by the inner and outer aluminum alloy plates.
[0029] Inside the lower housing 2, at the rear, is a control unit 20; inside the lower housing 2, on opposite sides, are respectively a limiting groove 22; on the front of the lower housing 2 is a control panel 7, and the control panel 7 and the control unit 20 are connected by a conduit and are electrically connected.
[0030] With the above structure, it should be further explained that the control unit 20 used in this invention is composed of several circuit boards. Each control unit 20 is electrically connected to the electrical control components of this invention via conduits. The connected control panel 7 is used to transmit switch and control commands to the control unit 20, thereby allowing the control unit 20 to control the opening or closing of the electrical components of this invention. Furthermore, the control unit 20 of this invention also extends through conduits to the outside of the lower housing 2, connecting to external control equipment and power supply.
[0031] The control panel 7 of this invention is a touch screen panel.
[0032] The lower housing 2 is connected to an external cooling device. The aluminum alloy plate can be cooled after placement using the external cooling device. Depending on the degree of cooling, the device can be changed to natural cooling or rapid cooling.
[0033] The guide groove 5 is closely attached to both sides inside the lower housing 2, and each side is provided with a protrusion. The two protrusions of the guide groove 5 are respectively embedded in each corresponding limiting groove 22. An opening is opened above the horizontal section 51 of the guide groove 5, and a glass plate is inlaid therein. An upwardly protruding arc surface is provided above the bottom of the horizontal section 51. An opening is provided on the arc surface of the horizontal section 51, and a guide roller is embedded in the opening. The guide roller provided in the horizontal section 51 is fixed to a guide motor 53. A slot is opened above the arc section of the guide groove 5, and a lever 54 is embedded in the slot of the guide groove 5. The lever 54 is consistent with the upper curved surface of the arc section of the guide groove 5. A rotating shaft runs horizontally through the lower end of the lever 54. One end of the rotating shaft of the lever 54 passes through the guide groove 5, and the other end of the lever 54 extends to the outside of the guide groove 5 and is connected to a swing motor 541. The horizontal section 51 and the inclined section 52 An internal channel 50 is provided. A vertical plate is provided at the end of the horizontal section 51 away from the inclined section 52. The downward-facing end of the inclined section 52 is open. At the lower opening of the inclined section 52, and on opposite sides of the channel 50, there are two guide wheels 521, each connected to a drive motor. At least two positioning contact pieces 55 are provided at the lower opening of the inclined section 52 and at the edge that is in contact with the upper opening of several storage slots 6. A conduit is connected to the side of the two positioning contact pieces 55 away from the upper side of several storage slots 6. The two positioning contact pieces 55 are connected to the corresponding drive motors via conduits. A pressing member 522 is provided on the side of the inclined section 52 facing the front of the upper box 1. The end of the pressing member 522 away from the inclined section 52 abuts against the lower box 2. The pressing member 522 is electrically connected to the output motor 53 and the swing motor 541 via conduits.
[0034] With the above structure, it should be further explained that when placing the document in the channel 50 of the horizontal section 51, the pressing member 522 located in the inclined section 52 is squeezed by the inner wall of the lower housing 2. This activates the swing motor 541, causing the lever 54 of the arc-shaped section to swing downwards, closing the channel 50 of the inclined section 52. This prevents the aluminum alloy plate from falling into the other storage slot 6 during the movement of the guide groove 5. After the pressing member 522 is no longer squeezed, the lever 54 also remains in the downward position. The aluminum alloy plate is positioned in a swing state, and the lever 54 is set with a moving arc. Therefore, during the movement of the guide groove 5, the aluminum alloy plate is not easy to fall from the opening of the lever 54. After reaching the storage groove 6 to be placed below the inclined section 52, the lever 54 is reset, and the aluminum alloy plate is pushed outward by the guide motor 53, allowing the aluminum alloy plate to move and slide down the inclined section 52 until it reaches the storage groove 6. At the same time, the two guide wheels 521 below also provide drive to guide the aluminum alloy plate into the storage groove 6.
[0035] When the aluminum alloy plate needs to be retrieved, the guide slot 5 moves to the corresponding storage slot 6. Each storage slot 6 has a sensor block at its opening edge. After the control unit 20 transmits the retrieval command to the storage slot 6, the sensor block is activated. When the two positioning contact pieces 55 of the inclined section 52 contact the sensor block, the solenoid valve 62 below the storage slot 6 pushes the aluminum alloy plate out. Finally, the aluminum alloy plate is guided into the transverse section 51 by two guide wheels 521. Two sensor blocks are provided, positioned at the front and rear edges of the opening of the storage slot 6. If we define them as sensing blocks 01 and 02, then the two positioning contact pieces 55 can be divided into positioning contact piece 551 and positioning contact piece 2. After sensing blocks 01 and 02 send signals to the outside, when positioning contact pieces 551 and positioning contact piece 2 move through the guide groove 5, in order to ensure that the opening below the inclined section 52 can ensure the opening above the corresponding storage groove 6, positioning contact piece 551 will stop when it contacts sensing block 01, while sensing block 01 will not stop when it contacts positioning contact piece 2. The signal sensing is connected to the moving motor 4 and is used to start and stop the moving motor 4.
[0036] When the pressing member 522 is pressed, it activates the outward extension of the outward extension motor 53 and the downward swing state of the paddle 54.
[0037] Each of the storage slots 6 is provided with a battery valve 62 below it, and a magnetic post is provided above the battery valve 62. The magnetic post passes through each of the storage slots 6. The top plate 61 in the storage slot 6 is connected to the top of the magnetic post below it. The top plate 61 moves back and forth along the slot opening of each of the storage slots 6 through the mutual cooperation between the magnetic post and the battery valve 62. Several of the battery valves 62 are respectively connected to the control unit 20 by conduits.
[0038] With the above structure, it should be further explained that after the opening below the inclined section 52 corresponds to the opening of the storage slot 6, the lower battery valve 62 is activated. The magnetic force generated by the battery valve 62 lifts the magnetic column, thereby driving the top plate 61 to lift the aluminum alloy plate. This method allows the aluminum alloy plate to be quickly ejected. Only the head end of the aluminum alloy plate needs to be ejected, and the aluminum alloy plate can be brought into the horizontal section 51 by the two guide wheels 521 below the inclined section 52. In order to ensure that the aluminum alloy plate can be brought into the horizontal section 51 by the inclined section 52, multiple sets of two opposing guide wheels 521 can be provided in the inclined section 52.
[0039] The width of the storage box 3 is the same as the width of the inlet groove 5; a viewing glass 31 is embedded on the top of the storage box 3; a top block 32 is provided inside the storage box 3, and one side of the top block 32 is attached to the end of the transverse section 51 of the inlet groove 5.
[0040] With the above structure, it should be further explained that in order to reduce the frequent taking out and putting in of documents, the present invention allows the horizontal section 51 to move into the storage box 3, and the aluminum alloy plate taken out can be observed through the viewing glass 31 of the storage box, so as to avoid bringing external dirt and dust into the cavity of the present invention after putting in the documents.
[0041] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
