Description

Technical Field

[0001] The invention belongs to the technical field of shoe drying, in particular to overheating automatic cut-off shoe drying equipment based on airflow circulation. Background Art

[0002] In the process of shoe production, operators need to glue the soles and the slopes together and put them into drying equipment for drying. The purpose is to optimize material properties, trigger chemical reactions, and stabilize product structures through thermodynamics. This is an irreplaceable process control point in the production process.

[0003] Generally, drying equipment is divided into two types, namely heating lamps (usually infrared radiation heating) and hot air (convection heating). Among them, hot air drying is generally used in heating scenarios that require relatively uniform temperature distribution and is suitable for complex structures or those that require penetration.

[0004] In the actual workflow, the operator only needs to put the bonded upper and sole into the drying equipment, wait for more than ten minutes for the glue to completely cure and complete the bonding of the upper and sole. However, in some cases, such as when the temperature is set too high or the fan speed is too low, the hot air cannot be evenly distributed, and the heat accumulates locally, causing the temperature in the drying box to be too high, which will affect the curing of the glue. At this time, if the operator takes out the shoe body, since the glue between the sole and the upper is not completely cured before taking it out, it may cause the bonding surface to debond. At the same time, some upper materials (such as leather) will gradually adapt to the temperature in the hot air environment. If they are suddenly taken out and exposed to normal temperature, the temperature difference may cause the leather fibers to shrink unevenly, resulting in wrinkles, hardening, or even cracking.

[0005] Therefore, in order to solve the above problems, an overheating automatic cut-off shoe drying device based on airflow circulation is proposed. Summary of the invention

[0006] In order to solve the problems raised in the above background technology, the present invention provides an overheating self-cut-off shoe drying equipment based on air flow circulation, which solves the problem that when the upper and sole are dried by reheated air, the temperature in the drying box is too high, resulting in unqualified quality of the cured shoe body.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an overheating self-cut-off shoe drying device based on airflow circulation, comprising a drying box and a metal pipe arranged inside the drying box, wherein a heating box is arranged on the metal pipe, and further comprising: a cooling mechanism arranged on the top of the drying box; a hot air bin and an air duct, which are connected and arranged below and above the cooling mechanism respectively; a temperature sensor, which is fixedly installed on the hot air bin; wherein the top end of the air duct is connected to a cold air blower for inputting cooling airflow into the cooling mechanism; The cooling mechanism comprises a heat-insulating box fixedly connected to the top of the drying box, a fin group 1 capable of storing coolant being fixedly connected to the heat-insulating box, a fin group 2 being movably mounted at the bottom of the heat-insulating box, a fin portion of the fin group 2 being insertable into a fin portion of the fin group 1, a lead screw motor for driving the fin group 1 to move in a vertical direction being fixedly connected to the top of the hot air bin, a liquid infusion pipe for inputting coolant into the fin group 1 and a liquid discharge pipe for discharging coolant from the fin group 1 being fixedly connected to the top of the heat-insulating box; One end of the metal tube is connected to the insulation box, and the other end is connected to the bottom of the drying box, and the other end of the insulation box is connected to the top of the hot air bin. The bottom of the hot air bin is equidistantly provided with air outlets connected to the top cavity of the drying box.

[0008] Preferably, the liquid infusion pipe is provided with a one-way valve 1 for limiting the one-way flow of the coolant into the fin group 1, and the liquid discharge pipe is provided with a one-way valve 2 for limiting the one-way flow of the coolant from the fin group 1 into the liquid discharge pipe; The bottom of the heat insulation box and the top of the fin group are equidistantly arranged; the inside of the drying box is vertically equidistantly arranged with shoe support plates.

[0009] Preferably, the heating box is composed of a heating coil sleeved on the outside of a metal tube and a fan connected to the metal tube.

[0010] Preferably, a one-way valve flap is provided at the bottom end of the air duct for one-way conduction between the air duct and the heat insulation box.

[0011] Preferably, the hot air bin is provided with an adjusting component for increasing the air outlet opening when the fin group 2 moves downward.

[0012] Preferably, the adjustment assembly comprises a connecting piece horizontally movably connected to the inside of the hot air bin, the connecting piece is equidistantly provided with damper plates of the same number as the air outlets, the connecting piece is hingedly provided with spring telescopic rods located outside the hot air bin on both sides, and the top end of the spring telescopic rod is hingedly connected to the bottom of the heat insulation box; The second fin group can drive the damper plate to move downward through the spring telescopic rod and the connecting piece, thereby increasing the opening of the air outlet.

[0013] Preferably, a spoiler component for mixing the airflow of the air duct and the cooling mechanism is provided inside the hot air bin; The regulating component can open the spoiler component during the process of moving to enlarge the air outlet.

[0014] Preferably, the spoiler assembly comprises spoiler plate 1 and spoiler plate 2 which are symmetrically and vertically staggered and hinged on the hot air bin, and a push rod is symmetrically and vertically movably connected inside the hot air bin, and the two top ends of the push rod can squeeze spoiler plate 1 and spoiler plate 2 respectively; The connecting member is symmetrically fixed with a convex shaft, and the bottom of the push rod is provided with an inclined surface that abuts against the top of the convex shaft. When the connecting member moves, the convex shaft can move along the inclined surface and make the push rod move downward, so that spoiler 1 and spoiler 1 rotate towards each other and have overlapping parts in the vertical direction.

[0015] Preferably, an exhaust assembly is provided on the side of the drying box.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The above scheme detects that the temperature inside the hot air bin is too high through the temperature sensor, cuts off the electric heating wire part in the heating box and keeps the fan running, and at the same time runs the screw motor to drive the fin group two downward. At the same time, the internal space of the fin group one increases and is in a negative pressure state, so that the coolant in the infusion tube is unidirectionally input into the fin group one. At this time, the heated gas input into the heat insulation box through the metal tube will contact the coolant inside it through the fin group one and achieve a cooling effect. Finally, the cooled gas will enter the hot air bin and be discharged through the air outlet. When the hot air bin detects that the temperature is normal, the screw motor drives the fin group two to reset and discharge the coolant inside the fin group one through the drain pipe, so as to ensure that when the temperature inside the box is too high, the device can cool the air flow temperature to ensure that the device can continue to dry the shoe body; In the above solution, when the fin group 2 moves downward, the spring telescopic rod pushes the connecting piece and the damper plate to move, thereby increasing the opening of the air outlet and making the exhausted gas more dispersed, so that the hot air is accumulated on the top of the drying box to prevent the hot air from blowing downward and damaging the shoe body; The above-mentioned scheme drives the cam shaft to move when the connecting part moves, so that the top of the cam shaft moves along the inclined surface, thereby the push rod moves downward. At this time, the two ends of the top of the push rod will respectively release the squeezing of spoiler 1 and spoiler 1, and spoiler 1 and spoiler 1 will rotate towards each other due to their own gravity. At this time, the gas input into the insulation box by the air duct will flow through the spoiler assembly and will be mixed with the gas in the cooling mechanism to reduce the overall temperature of the airflow before being discharged through the air outlet, further improving the cooling efficiency of the airflow.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figures 1 to 8 As shown, the present invention provides an overheating self-cut shoe drying device based on airflow circulation, including a drying box 1 and a metal pipe 2 arranged inside the drying box 1, a heating box 21 is arranged on the metal pipe 2, and the heating box 21 is composed of a heating coil sleeved on the outside of the metal pipe 2 and a fan connected to the metal pipe 2, and also includes: a cooling mechanism 3, which is arranged on the top of the drying box 1; a hot air bin 4 and an air duct 8, which are connected and arranged below and above the cooling mechanism 3 respectively; a temperature sensor 6, which is fixedly installed on the hot air bin 4; wherein the top end of the air duct 8 is connected to the cold air fan for inputting cooling airflow into the cooling mechanism 3; The cooling mechanism 3 includes a heat-insulating box 31 fixedly connected to the top of the drying box 1, a fin group 1 32 capable of storing coolant is fixedly connected to the heat-insulating box 31, a fin group 2 33 is movably installed at the bottom of the heat-insulating box 31, the fin part of the fin group 2 33 can be inserted into the fin part of the fin group 1 32, a screw motor 34 for driving the fin group 1 32 to move in the vertical direction is fixedly connected to the top of the hot air chamber 4, and a liquid infusion pipe 35 for inputting coolant into the fin group 1 32 and a liquid discharge pipe 36 for discharging coolant from the fin group 1 32 are fixedly connected to the top of the heat-insulating box 31; One end of the metal tube 2 is connected to the heat insulation box 31, and the other end is connected to the bottom of the drying box 1. The other end of the heat insulation box 31 is connected to the top of the hot air bin 4. The bottom of the hot air bin 4 is equidistantly provided with air vents 41 connected to the top cavity of the drying box 1. The liquid infusion pipe 35 is provided with a one-way valve 351 for limiting the one-way flow of the cooling liquid into the fin group 1 32, and the liquid discharge pipe 36 is provided with a one-way valve 361 for limiting the one-way flow of the cooling liquid from the fin group 1 32 into the liquid discharge pipe 36; The bottom of the heat insulation box 31 and the top of the fin group 1 32 are equidistantly provided with heat insulation boards 311; the interior of the drying box 1 is vertically equidistantly provided with shoe support boards 11; By adopting the above scheme, when the temperature sensor 6 detects that the temperature inside the hot air bin 4 is too high, the heating wire part in the heating box 21 is cut off and the fan is kept running, and at the same time, the screw motor 34 is operated to drive the fin group 2 33 downward. At the same time, the internal space of the fin group 1 32 increases and is in a negative pressure state, so that the coolant in the infusion tube 35 is unidirectionally input into the fin group 1 32. At this time, the heated gas input into the heat insulation box 31 through the metal tube 2 will contact the coolant inside it through the fin group 1 32 and achieve a cooling effect. Finally, the cooled gas will enter the hot air bin 4 and be discharged through the air outlet 41. When the hot air bin 4 detects that the temperature is normal, the screw motor 34 drives the fin group 2 33 to reset and discharge the coolant inside the fin group 1 32 through the drain pipe 36, thereby ensuring that when the temperature in the box is too high, the device can cool the air flow temperature to ensure that the device can continue to dry the shoe body.

[0021] like Figure 2 , Figure 5 , Figure 7 and Figure 8 As shown, the hot air bin 4 is provided with an adjustment component 5 for increasing the opening of the air port 41 when the fin group 2 33 moves downward; The adjustment component 5 includes a connecting piece 51 horizontally movably connected to the inside of the hot air bin 4, and the connecting piece 51 is equidistantly provided with damper plates 52 equal in number to the air outlets 41, and both sides of the connecting piece 51 are hinged with spring telescopic rods 53 located outside the hot air bin 4, and the top of the spring telescopic rod 53 is hinged to the bottom of the heat insulation box 31; The downward movement of the fin group 2 33 can drive the damper plate 52 to move through the spring telescopic rod 53 and the connecting member 51, thereby increasing the opening of the air outlet 41; With the above solution, when the fin group 2 33 moves downward, the spring telescopic rod 53 pushes the connecting member 51 and the damper plate 52 to move, thereby increasing the opening of the air outlet 41 and making the exhausted gas more dispersed, so that the hot air is accumulated on the top of the drying box 1 to prevent the hot air from blowing downward and damaging the shoe body; like Figure 1-Figure 4 and Figure 7As shown, a one-way valve flap 81 for one-way communication between the air duct 8 and the heat insulation box 31 is provided at the bottom of the air duct 8; a spoiler component 7 for mixing the airflow of the air duct 8 and the cooling mechanism 3 is provided inside the hot air chamber 4; the regulating component 5 can open the spoiler component 7 in the process of moving to enlarge the air outlet 41; The spoiler assembly 7 includes a spoiler plate 1 71 and a spoiler plate 2 72 which are symmetrically and vertically staggered and hinged on the hot air bin 4. A push rod 73 is symmetrically and vertically movably connected inside the hot air bin 4. The two top ends of the push rod 73 can squeeze the spoiler plate 1 71 and the spoiler plate 2 72 respectively. The connecting member 51 is symmetrically fixed with a convex shaft 511, and the bottom of the push rod 73 is provided with an inclined surface 731 which is in contact with the upper part of the convex shaft 511. When the convex shaft 511 moves with the connecting member 51, it can move along the inclined surface 731 and make the push rod 73 move downward, so that the spoiler plate 2 72 and the spoiler plate 1 71 rotate towards each other and have an overlapping part in the vertical direction; the side of the drying box 1 is connected with an exhaust assembly 12; By adopting the above scheme, when the connecting member 51 moves, the convex shaft 511 is driven to move, so that the top of the convex shaft 511 moves along the inclined surface 731, so that the push rod 73 moves downward, and at this time, the two ends of the top of the push rod 73 will release the squeezing of the spoiler 1 71 and the spoiler 2 72 respectively, and the spoiler 1 71 and the spoiler 2 72 will rotate towards each other due to their own gravity. At this time, the gas input into the heat insulation box 31 by the air duct 8 will flow through the spoiler assembly 7 and will be mixed with the gas in the cooling mechanism 3 to reduce the overall temperature of the air flow and then discharged through the air outlet 41, and then mixed with the hot air accumulated on the top of the drying box 1 and blown out to achieve continued drying of the shoe body; At the same time, the excess gas entering the drying box 1 will be filtered and discharged through the exhaust component 12; The working principle and use process of the present invention: When the temperature sensor 6 detects that the temperature inside the hot air bin 4 is too high, the electric heating wire part in the heating box 21 is first disconnected, and the fan is kept running. At the same time, the screw motor 34 is operated to drive the fin group 2 33 downward. At this time, the internal space of the fin group 1 32 increases and is in a negative pressure state, so that the coolant in the infusion pipe 35 is unidirectionally input into the fin group 1 32. At this time, the heated gas input into the heat insulation box 31 through the metal pipe 2 will contact the coolant inside it through the fin group 1 32 and achieve a cooling effect. Finally, the cooled gas will enter the hot air bin 4 and be discharged through the air outlet 41. When the hot air bin 4 detects that the temperature is normal, the screw motor 34 drives the fin group 2 33 to reset and discharge the coolant inside the fin group 1 32 through the drain pipe 36; When the second fin group 33 moves downward, the spring telescopic rod 53 will push the connecting piece 51 and the damper plate 52 to move, thereby increasing the opening of the air outlet 41 and making the discharged hot air more dispersed. It is worth noting that the operator can also reverse the inclination of the spring telescopic rod 53 so that when the second fin group 33 moves downward, the spring telescopic rod 53 can drive the connecting piece 51 and the damper plate 52 to move and reduce the opening of the air outlet 41, thereby increasing the flow rate of the airflow through the air outlet 41 and preventing the hot air from accumulating under the hot air bin 4. When the connecting member 51 moves, it will also drive the cam 511 to move, so that the top of the cam 511 moves along the inclined surface 731, so that the push rod 73 moves downward. At this time, the two ends of the top of the push rod 73 will respectively release the squeezing of the spoiler 1 71 and the spoiler 2 72, and the spoiler 1 71 and the spoiler 2 72 will rotate towards each other due to their own gravity. At this time, the gas input by the air duct 8 to the heat insulation box 31 will flow through the spoiler assembly 7 and will be mixed with the gas in the cooling mechanism 3 to reduce the overall temperature of the air flow and then be discharged through the air outlet 41.
