Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0033] Embodiment one The present application provides a kind of drying equipment for inductance production as shown in Figures 1 to 12 The present application includes box 1 and box door 10, and further includes cross partition 2, which is placed in the top of box 1;The present application is divided into box 1 space by setting cross partition 2.

[0034] Two air uniformization components 3 are placed on both sides of cross partition 2, and are detachably connected with cross partition 2 and box 1;The present application makes the air flow uniformly blow to the inductance to be heated by setting air uniformization component 3, so as to uniformly dry the inductance, thereby improving the quality of product drying.

[0035] Specifically, air uniformization component 3 includes ventilation plate 301, and a plurality of through holes are arranged in array on the surface of ventilation plate 301;The present application realizes uniform flow of air passing through ventilation plate 301 by arranging through holes in array.

[0036] A plurality of linear array arranged electric heating components 4 are placed between air uniformization component 3 and the inner wall of box 1;The present application heats the air by electric heating component 4 to realize drying, and at the same time, by setting electric heating component 4 as a plurality of components, it can be matched with blocking component 5 to realize partition blocking.

[0037] Blocking component 5 is placed between air uniformization component 3 and electric heating component 4, and is connected with air uniformization component 3, which is used to control the electric heating component 4 above the placement height of inductance to be dried according to the placement height of inductance to be dried, so that the blocking component 5 above the placement height of inductance to be dried blocks air uniformization component 3;The present application controls the electric heating component 4 above the placement height of inductance to be dried to work and heats to a first preset temperature after the inductance is placed in box 1, so that the blocking component 5 blocks the corresponding air uniformization component 3 above the placement height of inductance to be dried, so as to adjust the air outlet area of air uniformization component 3, select the air outlet height according to the placement height of inductance, prevent part of hot air from flowing away directly through air circulation component 6 without inductance, maximize the heated air to pass through inductance, thereby improving the drying efficiency.

[0038] Air circulation component 6 is used to make the air flow in box 1 circulate.

[0039] Specifically, air circulation component 6 includes circulation fan 601, which penetrates cross partition 2 and is fixedly connected with cross partition 2;The present application realizes the circulation of air flow in box 1 by setting circulation fan 601, so as to realize rapid drying.

[0040] A wind guide cylinder 602 is arranged on the top of the box body 1 and communicates with the inside of the box body 1, and a valve with adjustable opening degree is arranged in the inside of the wind guide cylinder 602. The valve with adjustable opening degree is arranged, so that the opening and closing of the wind guide cylinder 602 is controlled.

[0041] Two symmetrical electric air inlet doors 603 are further arranged on the inner side wall of the top of the box body 1.

[0042] Specifically, the electric air inlet door 603 is provided with an air filtering assembly, and the air filtering assembly is a prior art and will not be described here.

[0043] Specifically, the plugging assembly 5 includes two symmetrical guide columns 501 which are in sliding connection with the air equalizing assembly 3, the guide columns 501 are arranged on the air equalizing assembly 3, and the guide columns 501 are arranged on the air equalizing assembly 3.

[0044] A plurality of plugging pieces 502 are arranged in a linear array and are connected with the middle circumferential wall of the guide column 501 and connected with the air equalizing assembly 3 through a reset piece, the plugging pieces 502 are arranged to plug the air equalizing assembly 3.

[0045] A bimetallic strip 503 is connected with one end of the guide column 501 close to the inner wall of the box body 1 through a connecting plate and connected with the air equalizing assembly 3, the bimetallic strip 503 is arranged to achieve the following two aspects: first, the bimetallic strip 503 is deformed by heating the electric heating assembly 4 to a first preset temperature, so as to pull the guide column 501 and the plugging piece 502 to move towards the air equalizing assembly 3 and plug the air equalizing assembly 3; second, the bimetallic strip 503 is deformed by heating the electric heating assembly 4 to a second preset temperature, so as to unlock the locking assembly 504 and release the plugging of the plugging piece 502 to the air equalizing assembly 3.

[0046] The locking assembly 504 is arranged on the end of the plugging piece 502 and is used for limiting and locking the plugging piece 502 and the air equalizing assembly 3, the bimetallic strip 503 is deformed by heating the electric heating assembly 4 to a first preset temperature, so as to pull the guide column 501 and the plugging piece 502 to move towards the air equalizing assembly 3 and lock the locking assembly 504; in the locked state, the plugging piece 502 is always in the plugging state; in the unlocked state, the plugging piece 502 no longer plugs the air equalizing assembly 3, that is, the plugging of the plugging piece 502 to the air equalizing assembly 3 is released.

[0047] Further, the locking assembly 504 includes an extension plate 5041 arranged on the side of the plugging piece 502 close to the air equalizing assembly 3, the extension plate 5041 is arranged to support and fix the limiting column 5042.

[0048] The limiting column 5042 is connected with the extension plate 5041 through sliding, and is connected with the extension plate 5041 through a reset member, and the bottom is a slope; the reset member and the limiting column 5042 are arranged, so that the limiting column 5042 and the extension plate 5041 are connected through sliding reset.

[0049] The fixed column 5043 is connected with the air equalizing assembly 3 at one end, and the other end is fixedly provided with a limiting circular table 5046; the limiting circular table 5046 can cooperate with the limiting column 5042 to limit the limiting column 5042.

[0050] Further, the large-diameter end of the limiting circular table 5046 is fixedly connected with the fixed column 5043.

[0051] The limiting ring 5044 is fixedly sleeved on one end of the fixed column 5043 connected with the air equalizing assembly 3.

[0052] The sliding unlocking ring 5045 is slidably sleeved on the fixed column 5043 and located between the limiting ring 5044 and the limiting circular table 5046, and is used for unlocking the limiting column 5042 and the limiting circular table 5046. The sliding unlocking ring 5045 is arranged, and the limiting column 5042 and the limiting circular table 5046 are unlocked through the sliding unlocking ring 5045.

[0053] Further, the sliding unlocking ring 5045 includes two symmetrically arranged circular tables, the large-diameter ends of the two circular tables are oppositely arranged, the small-diameter ends of the two circular tables are oppositely arranged, and the two circular tables are provided with through holes for the fixed column 5043 to pass through.

[0054] The blocking member 502 includes a support portion 5021, and a plurality of blocking portions 5022 are arranged on one side of the support portion 5021 close to the air equalizing assembly 3; the blocking portions 5022 are arranged, so that the through holes on the air equalizing assembly 3 are blocked.

[0055] The circumferential wall of the blocking portion 5022 is provided with an annular groove 5023, when the limiting column 5042 and the limiting circular table 5046 are in the locked state, and the blocking portion 5022 moves to the air equalizing assembly 3, the annular groove 5023 is communicated with the through hole on the air equalizing assembly 3, at this time, the blocking is released. The annular groove 5023 is arranged, when the limiting column 5042 and the limiting circular table 5046 are locked, if the blocking portion 5022 continues to move to the air equalizing assembly 3, the annular groove 5023 is communicated with the through hole on the air equalizing assembly 3, at this time, the air equalizing assembly 3 cannot be completely blocked, so that the bimetallic strip 503 can be quickly cooled during the reset process.

[0056] First, the inductance to be dried is placed in the box 1, then according to the height of the inductance to be placed, the electric heating assembly 4 above the height of the inductance to be placed is controlled to work and heated to a first preset temperature, the electric heating assembly 4 is heated to the first preset temperature, causing the bimetallic strip 503 to deform, the deformation of the bimetallic strip 503 will pull the guide column 501 and the blocking piece 502 to move to one side of the air equalizing assembly 3, the limiting column 5042 is in contact with the side wall of the limiting circular table 5046, when heated to the first preset temperature, after overcoming the elastic force of the restoring member on the limiting column 5042, the limiting column 5042 and the limiting circular table 5046 form a limit, at this time the blocking piece 502 completely blocks the air equalizing assembly 3, achieving locking.

[0057] It should be emphasized that the first preset temperature is greater than the normal drying temperature.

[0058] Then control the electric heating assembly 4 below the height of the inductance to be placed to work, control the air circulation assembly 6 to work, and perform internal circulation, the airflow passes through the space where the inductance to be dried is placed, the air circulation assembly 6, the space between the horizontal partition plate 2 and the top of the box 1, the space between the box 1 and the air equalizing assembly 3, and finally returns to the space where the inductance to be dried is placed, thereby realizing internal circulation drying; since the air equalizing assembly 3 corresponding to the area where the inductance is not placed is blocked, the high-temperature airflow is prevented from entering the circulating fan 601 directly without passing through the inductance, thereby achieving energy saving.

[0059] When the internal humidity is too high, the electric air inlet door 603 in the air circulation assembly 6 is controlled to open, then the valve opening degree is controlled to open a preset opening degree, under the action of negative pressure, external dry airflow will enter, and part of the humid airflow will flow out through the valve, thereby realizing that under the condition of internal circulation, external dry air enters and internal humid air is discharged, thereby achieving dehumidification.

[0060] After the drying is completed, according to the height of the inductance placed, by controlling the working of the circulating fan 601, the opening of the electric air inlet door 603 and the full opening of the valve opening, the internal rapid cooling is realized due to the entry of the external drying low-temperature gas; then the electric air inlet door 603 is controlled to be closed and the circulating fan 601 is stopped working, and then the electric heating assembly 4 above the inductance placed height is controlled to work to heat to a second preset temperature, the second preset temperature is greater than the first preset temperature, the electric heating assembly 4 is heated to the second preset temperature, causing the bimetallic strip 503 to deform, the bimetallic strip 503 deformation will continue to pull the guide column 501 and the blocking piece 502 to move to one side of the air distribution assembly 3, so that the limiting column 5042 slides over the sliding unlocking ring 5045, and the limiting column 5042 is located between the sliding unlocking ring 5045 and the air distribution assembly 3, then the electric air inlet door 603 is controlled to be opened and the circulating fan 601 is controlled to be opened, due to the fact that the limiting column 5042 is located between the sliding unlocking ring 5045 and the air distribution assembly 3 at this time, and the setting of the annular groove 5023, the blocking piece 502 does not completely block the air distribution assembly 3, so that the drying gas flow directly passes through the through hole on the air distribution assembly 3 and is discharged after the circulating fan 601, so that the bimetallic strip 503 can be rapidly cooled and the bimetallic strip 503 can be rapidly reset, the bimetallic strip 503 reset will push the limiting column 5042 and the blocking piece 502 to reset, preparing for the next drying.

[0061] During the drying process, by changing the heating temperature of the electric heating assembly 4 below the inductance placed height to be dried, the blocking piece 502 can partially and partitionedly block the air distribution assembly 3 below the inductance placed height to be dried, so that the gas flow path can be changed, the air supply in one direction for a long time is avoided, the gas flow is improved, so that the inductance to be dried can be heated more uniformly, and the drying efficiency is improved.

[0062] After the drying is completed, by controlling all the electric heating assemblies 4 except the bottommost electric heating assembly 4 to heat to the first preset temperature, the bimetallic strip 503 is deformed, the bimetallic strip 503 deformation will pull the guide column 501 and the blocking piece 502 to move to one side of the air distribution assembly 3, so that the limiting column 5042 and the limiting circular table 5046 form a limit, at this time the blocking piece 502 completely blocks the air distribution assembly 3, so that only the through hole of the lowermost air distribution assembly 3 is opened, by opening the circulating fan 601, the electric air inlet door 603 and the valve opening, the dust at the bottom of the box 1 is taken away under the action of the gas negative pressure, so that the inside of the box 1 is cleaned.

[0063] Embodiment two Based on the above embodiment, in actual use, the air filter assembly is arranged at the electric air inlet door 603. Due to the arrangement of the air filter assembly, the air filter assembly is easily blocked after long-term use, which causes the problems of small air inlet, poor dehumidification effect, and poor cooling effect after drying, and also affects the recovery of the bimetallic strip 503, resulting in long recovery time of the bimetallic strip 503 and the sealing assembly 5 cannot immediately adjust for the next drying. To solve the above technical problems, the following improvements are made on the basis of the first embodiment.

[0064] The air guide cylinder 602 is connected to the top of the box body 1 through the support.

[0065] The air circulation assembly 6 further comprises a conical air guide part 604 arranged at the top of the circulating fan 601 and arranged in a large size at the top and a small size at the bottom. The conical air guide part 604 is arranged to guide part of the air blown by the circulating fan 601 to the adjusting fan 612.

[0066] The first vertical air guide part 605 is arranged at the top of the conical air guide part 604, and the circumferential side wall is circumferentially arrayed with the first air vent hole 606. The first vertical air guide part 605 is arranged to directly guide part of the air blown by the circulating fan 601 to the top of the box body 1.

[0067] The second vertical air guide part 607 is arranged inside the first vertical air guide part 605 and at the top of the circulating fan 601, and is connected to the middle part of the first vertical air guide part 605 through the support plate 608. The support plate 608 is circumferentially arrayed with a plurality of second air vent holes 609, and the second air vent holes 609 are distributed in a staggered manner with the first air vent holes 606. The second vertical air guide part 607 is arranged to guide part of the air blown by the circulating fan 601 to the adjusting fan 612 in cooperation with the conical air guide part 604.

[0068] As shown in Figure 12 The adjusting fan 612 is arranged between the first vertical air guide part 605 and the second vertical air guide part 607, and is rotatably connected to the first vertical air guide part 605 and is driven by the rotating motor through the gear transmission mechanism.

[0069] The air direction adjusting part 610 is rotatably arranged in the space surrounded by the first vertical air guide part 605, the second vertical air guide part 607 and the support plate 608, and is used for plugging the first air vent hole 606 or the second air vent hole 609.

[0070] The adjusting cylinder 611 is sleeved outside the air guide cylinder 602, and can be inserted and connected with the air direction adjusting part 610. Specifically, the adjusting cylinder 611 is provided with an insertion slot at the bottom, and the air direction adjusting part 610 is provided with an insertion part at the top matched with the insertion slot.

[0071] A driving mechanism 7 is arranged to drive the rotation and vertical movement of the adjusting cylinder 611.

[0072] A plurality of air supplement valves 9 are arranged in a circumferential array on the top of the box 1 and communicate with the interior of the box 1.

[0073] Specifically, the driving mechanism 7 comprises an outer gear ring 701 which is sleeved on the top of the air direction adjusting member 610.

[0074] A rotating ring 702 is rotatably sleeved on the outer gear ring 701 and is connected to the top of the box 1 through the height adjusting assembly 8. Specifically, the height adjusting assembly 8 is an electric telescopic member, which can be a pneumatic telescopic rod or a hydraulic telescopic rod. By arranging the height adjusting assembly 8, the telescopic control of the height adjusting assembly 8 drives the rotating ring 702 to move up and down, which drives the outer gear ring 701 and the adjusting cylinder 611 to move up and down, thereby adjusting the height of the adjusting cylinder 611.

[0075] A gear 703 is engaged with the outer gear ring 701 and is driven by a driving motor 704.

[0076] By arranging the driving mechanism 7, the driving motor 704 is controlled to work, which drives the gear 703 to rotate, the gear 703 drives the rotating ring 702 to rotate, the rotating ring 702 drives the outer gear ring 701 to rotate, and the outer gear ring 701 drives the adjusting cylinder 611 to rotate, thereby achieving the rotation adjustment of the adjusting cylinder 611.

[0077] In use, before the air filtering assembly is blocked and before normal drying is performed, the driving mechanism 7 is controlled to drive the adjusting cylinder 611 to move downward and be inserted with the air direction adjusting member 610, then the adjusting cylinder 611 is driven to rotate to the position where the air direction adjusting member 610 blocks the first air vent 606, the rotation of the adjusting cylinder 611 drives the air direction adjusting member 610 to rotate, thereby blocking the first air vent 606. Since the first air vent 606 and the second air vent 609 are arranged in a staggered manner, the second air vent 609 is not blocked at this time. Then, the driving mechanism 7 is controlled to drive the adjusting cylinder 611 to move upward.

[0078] Then, in the normal drying process, the circulating fan 601 and the adjusting fan 612 are controlled to work simultaneously, the air blown by the circulating fan 601 enters the second vertical air guide part 607 and the conical air guide part 604, the air from the second vertical air guide part 607 directly reaches the top of the box 1 and is guided to the surrounding area from the top of the box 1, and the air from the conical air guide part 604 reaches the adjusting fan 612 through the first air vent 606 and the first vertical air guide part 605. Under the action of the adjusting fan 612, the air is blown again, so that the air can be more uniformly guided to the surrounding area, and the products in the box 1 can be more uniformly dried.

[0079] When the internal humidity is excessive, and the air filter assembly is severely blocked, by controlling the driving mechanism 7, the driving adjustment cylinder 611 is driven to move down and plug with the air direction adjusting piece 610, and then the driving adjustment cylinder 611 is driven to rotate to the position where the air direction adjusting piece 610 blocks the second air vent 609, so as to achieve the blocking of the second air vent 609. Since the second air vent 609 and the first air vent 606 are staggered, at this time, the first air vent 606 is not blocked. Then control the electric air inlet door 603 in the air circulation assembly 6 to close, and then control the valve opening to be fully open, control the air supplement valve 9 to open, and at the same time control the circulating fan 601 to start, and at the same time control the adjusting fan 612 to reverse, so that the air passes through the air supplement valve 9, the electric heating assembly 4, the air distribution assembly 3, the space for placing the inductor to be dried, the circulating fan 601 and the second vertical air guide part 607, and finally is discharged through the air guide cylinder 602, so as to take away the internal hot and humid air. The air after entering the air supplement valve 9 is partly taken away by the adjusting fan 612, and the other part directly reaches the electric heating assembly 4. Under the action of the adjusting fan 612, the air passing through the adjusting fan 612 is finally diffused to the surrounding through the first vertical air guide part 605 and the first air vent 606, so as to make more air diffuse to the surrounding, and realize more uniform air distribution in the middle and the surrounding.

[0080] When the air filter assembly is severely blocked, and heat dissipation is needed after drying is completed, according to the height of the inductor to be placed, by controlling the circulating fan 601 to work, the adjusting fan 612 to reverse, the electric air inlet door 603 to close, the air supplement valve 9 to open and the valve opening to be fully open, since the external dry low-temperature gas enters, the internal temperature is rapidly reduced. Then control the circulating fan 601 to stop working, and the adjusting fan 612 to stop working, and then control the electric heating assembly 4 above the height of the inductor to be placed to work, heat to the second preset temperature, and the second preset temperature is greater than the first preset temperature. The electric heating assembly 4 is heated to the second preset temperature, causing the bimetallic strip 503 to deform. The deformation of the bimetallic strip 503 will continue to pull the guide column 501 and the blocking piece 502 to move to one side of the air distribution assembly 3, so as to make the limiting column 5042 slide over the sliding unlocking ring 5045, so that the limiting column 5042 is located between the sliding unlocking ring 5045 and the air distribution assembly 3. Then control the circulating fan 601 to work, the adjusting fan 612 to reverse, the electric air inlet door 603 to close, the air supplement valve 9 to open and the valve opening to be fully open. Since the limiting column 5042 is located between the sliding unlocking ring 5045 and the air distribution assembly 3 at this time, and the annular groove 5023 is arranged, the blocking piece 502 does not completely block the air distribution assembly 3 above the height of the inductor to be placed, so that the dry airflow directly passes through the through hole on the air distribution assembly 3 and is discharged after passing through the circulating fan 601, so as to realize rapid cooling of the bimetallic strip 503 and rapid resetting of the bimetallic strip 503. The resetting of the bimetallic strip 503 will push the limiting column 5042 and the blocking piece 502 to reset, in preparation for the next drying. In summary, when the air filter assembly is severely blocked, heat dissipation, drying and moisture removal can still be performed.

[0081] Finally, it should be noted that the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, as long as within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
