[0001] This invention relates to the field of shoe manufacturing technology, specifically to a shoe sole drying device for the production and processing of casual shoes. Background Technology

[0002] In the production of casual shoes, drying the sole is a crucial step before bonding. The glue applied to the sole surface is activated by heating, and the adhesive layer is heated by hot air circulation, infrared rays, etc., to achieve the best bonding state.

The first heating mechanism includes a set of spiral flat tubes and at least one fan. The casters include a connecting body, a rotating assembly, and wheels, which can reduce the impact on people's health; it has a high degree of automation, saving time and labor; it improves drying efficiency; it saves time and labor when moving, and its structure is more stable.

[0004] For example, in the prior art, Chinese patent application number CN201710569203.6 discloses a drying and conveying device for adhesive shoe soles, including a conveyor belt, an oven, a curtain, a controller, an infrared sensor, a telescopic rod, a timer, a fixing block, a heating element, shoes, a foot rack, a shoe placement board, a motor, and a switch button. The upper surface of the conveyor belt is provided with a shoe placement board, on which shoes are placed. An oven is provided on one side of the shoe placement board. A foot rack is provided at the bottom of the oven. A curtain is provided on one side of the oven. A controller is provided inside the oven. An infrared sensor is provided at the bottom of the controller. The bottom of the infrared sensor is connected to one end of the telescopic rod. A timer is installed on the telescopic rod. The other end of the telescopic rod is connected to a fixing block. A heating element is provided on the fixing block. A motor is installed at the bottom of the conveyor belt. A switch button is provided on the motor. This is a drying and conveying device for adhesive shoe soles.

[0005] For example, in the prior art, Chinese patent application number CN201710555657.8 discloses a drying device for shoe soles after gluing. A protective cover is fixedly connected between two insulated boxes. A steam heating pipe passes through the two insulated boxes and the protective cover. Two conveyor wheels are respectively rotatably located on the outside of the two insulated boxes. The conveyor belt on the conveyor side passes through the steam heating pipe inside the two insulated boxes. The exhaust pipe is located above the insulated box, and the exhaust end of the exhaust pipe is sealed to the exhaust box. A water tank is located inside the exhaust box. Two water curtain plates are arranged parallel to each other in the water tank. Two spray pipes are respectively sealed to the inlet and outlet of the water pump. The spray pipe located at the inlet extends into the water tank. Two spray heads are connected to the spray pipe located at the outlet, and the two spray heads are correspondingly located above the two water curtain plates. An exhaust port is provided on the exhaust box, which is located between the two water curtain plates. The exhaust fan is connected to the exhaust port.

[0006] Based on the above information, it can be seen that existing technologies generally use hot air circulation to dry shoe soles. However, in actual use, the surface of shoe soles is generally irregular in shape, and hot air does not easily reach some grooves, affecting the overall drying effect. Summary of the Invention

[0007] The purpose of this invention is to provide a shoe sole drying device for casual shoe production and processing, so as to solve the problem mentioned in the background art that the grooves on the shoe sole surface affect the drying effect.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a shoe sole drying device for casual shoe production and processing, comprising a support base placed horizontally on the ground, a drying chamber fixedly installed above the support base, a conveyor platform with a built-in conveyor belt fixedly installed at the upper end of the support base, and mounting platforms fixedly installed at equal intervals above the conveyor belt, a placement mold containing shoe soles engaging with the mounting platforms, the mounting platforms being made of soft rubber material and capable of bending synchronously with the conveyor belt, a contact plate being installed at the upper end of the placement mold to abut against the lower surface of the shoe sole, and the contact plate being connected to a vibration mechanism inside the placement mold, the vibration mechanism driving the contact plate to vibrate the shoe sole, a through hole being opened at the upper inner side of the placement mold, hot air being sprayed out of the through hole to heat the glue applied to the surface of the shoe sole from the side, a heating nozzle being fixedly installed inside the drying chamber, and the heating nozzle being connected to a conveying pump fixedly installed on the upper surface of the drying chamber through a first connecting pipe, and the first connecting pipe flowing through a heater to heat the air, the heater being equipped with an electric heating wire inside, the electric heating wire heating the air entering the heater when energized.

[0009] Preferably, air collecting hoods are fixedly installed on the outer surfaces of the left and right sides of the drying box, and the air collecting hoods are connected to the delivery pump through the second connecting pipe. The delivery pump flows through the filter box, which is filled with filter cotton and filter membrane. The filter cotton filters large particulate impurities in the air, and the filter membrane filters harmful substances in the air.

[0010] Preferably, the vibration mechanism includes a piston plate horizontally installed inside the placement mold, and the piston plate slides against the inner wall of the placement mold. A return spring is fixedly installed between the upper surface of the piston plate and the inner wall of the placement mold. The piston plate is fixedly connected to the contact plate through a connecting rod. During the up-and-down movement of the piston plate, the contact block moves up and down synchronously through the connecting rod, thereby using the connecting rod to push the shoe sole inside the placement mold to vibrate up and down, so that the dried and activated glue can penetrate into the grooves and gaps of the shoe sole, improving the adhesion effect of the glue.

[0011] Preferably, an electromagnet is fixedly installed on the lower surface of the piston plate, and the electromagnet corresponds to the position of a permanent magnet fixedly installed inside the mounting platform. The piston plate slides up and down through the magnetic interaction between the electromagnet and the permanent magnet. The permanent magnet is made of flexible magnetic material and can deform synchronously with the mounting platform.

[0012] Preferably, a receiving metal sheet is fixedly installed on the front side of the placement mold, and the receiving metal sheet is in contact with the power supply metal sheet. The power supply metal sheet is fixedly installed in the middle position inside the conveyor table, and an alternating current flows through the power supply metal sheet. Both the receiving metal sheet and the power supply metal sheet are made of copper. When they are in contact, the current is connected, and the current flows through the power supply metal sheet into the receiving metal sheet, and finally powers the electromagnet through the wire.

[0013] Preferably, air inlet pipes connected to the interior of the mold are fixedly installed on both sides of the mold, and the air inlet pipes are located below the piston plate. An exhaust pipe is fixedly installed on the upper surface of the piston plate. One-way valves are provided on the outside of both the air inlet pipe and the exhaust pipe. Air can only enter through the air inlet pipe and exit through the exhaust pipe, and cannot flow in the opposite direction. The through holes are connected to the interior of the mold, and the through holes are evenly distributed at equal intervals. Finally, hot air is discharged from the through holes to achieve the purpose of heating the sole from the side and improving the uniformity of the sole heating.

[0014] Preferably, a strip-shaped magnetic block is embedded inside the connecting rod, and a limiting sleeve is fixedly installed inside the upper end of the placement mold. The connecting rod and the limiting sleeve are slidably connected, and the limiting sleeve is made of copper. When the magnet falls inside the copper tube, the magnetic field around it moves relative to the copper tube wall. According to Lenz's law, the direction of the magnetic field generated by the induced current always attempts to counteract the cause of its change. Therefore, the magnetic field generated by the eddy current interacts with the magnetic field of the falling magnet, producing a force that opposes the relative motion of the magnet, thereby slowing down the magnet's movement.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the shoe sole drying equipment for casual shoe production and processing adopts a novel structural design, the specific details of which are as follows: 1. After the mold is transported into the drying chamber by the conveyor belt, the energized metal plate on the front of the mold reaches the position of the power supply metal plate and the current is turned on. At this time, the alternating current provided by the power supply device powers the electromagnet, and the magnetic direction of the electromagnet is changed periodically. In conjunction with the permanent magnet on the inner side of the mounting platform, the magnetic attraction and repulsion drive the piston plate to move up and down. The piston plate discharges hot air from the through hole, so as to achieve the purpose of heating the sole from the side and improve the uniformity of heating the sole. Furthermore, during the up-and-down movement of the piston plate, the connecting rod drives the contact block to move up and down synchronously, thereby using the connecting rod to push the shoe sole placed inside the mold to vibrate up and down, so that the dried and activated glue can penetrate into the grooves and gaps of the shoe sole, improving the adhesion of the glue.

[0016] 2. After the mold is removed from the mounting table, the permanent magnet loses its attraction to the electromagnet (the electromagnet has a steel core, which the permanent magnet attracts). At this time, the piston plate is pulled upward by the return spring. The bar magnet embedded in the connecting rod moves in the copper limiting sleeve. The electromagnetic damping effect (that is, when the magnet moves in the copper tube, the magnetic field around it moves relative to the copper tube wall. According to Lenz's law, the direction of the magnetic field generated by the induced current always tries to cancel the cause of its change. Therefore, the magnetic field generated by the eddy current will interact with the magnetic field of the falling magnet, generating a force that opposes the relative motion of the magnet) slows down the movement speed of the piston plate, thereby slowly expelling the hot air inside the mold through the through hole and prolonging the heat preservation time of the shoe sole.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figures 1-4 In order to achieve the purpose of drying the shoe sole and activating the glue, this embodiment provides the following technical solution, which specifically discloses: a support base 1 placed horizontally on the ground, a drying box 2 fixedly installed on the support base 1, a conveyor platform 3 with a built-in conveyor belt 4 fixedly installed on the upper end of the support base 1, and mounting platforms 6 fixedly installed at equal intervals above the conveyor belt 4, a mold 5 containing the shoe sole and mounting platforms 6 engaging with each other, a heating nozzle 20 fixedly installed inside the drying box 2, and the heating nozzle 20 connected to a conveying pump 21 fixedly installed on the upper surface of the drying box 2 through a first connecting pipe 22, and the first connecting pipe 22 flows through a heater 23 to heat the air, and air collecting hoods 24 fixedly installed on the outer surfaces of the left and right sides of the drying box 2, and the air collecting hoods 24 connected to the conveying pump 21 through a second connecting pipe 25, and the conveying pump 21 flows through a filter box 26.

[0021] When using the device, the operator first places the shoe sole coated with glue into the groove above the placement mold 5. Then, the placement mold 5 containing the shoe sole is placed sequentially into the mounting platform 6 above the conveyor belt 4. The mounting platform 6 clamps and fixes the placement mold 5. Then, the conveyor belt 4 is turned on to transport the placement mold 5 into the drying chamber 2. At this time, the conveyor pump 21 above the drying chamber 2 is turned on to deliver air into the heater 23. The electric heating wire inside the heater 23 heats the air. The heated air is delivered to the heating nozzle 20 through the first connecting pipe 22 and sprayed out to heat the shoe sole, thereby activating the glue applied to the surface of the shoe sole. At the same time, the conveyor pump 21 draws in air through the second connecting pipe 25 in conjunction with the air collection hood 24. The air drawn in is the hot air around the drying chamber 2, thereby achieving the purpose of waste heat utilization and reducing the power consumption of the heater 23.

[0022] Example 2: Please refer to Figures 5-8 To improve the uniformity of heat distribution on the sole, this embodiment provides the following technical solution: A contact plate 7 is installed on the upper end of the placement mold 5, which contacts the lower surface of the sole. The contact plate 7 is connected to a vibration mechanism inside the placement mold 5. The vibration mechanism drives the contact plate 7 to vibrate the sole. A through hole 17 is provided on the inner side of the upper end of the placement mold 5, through which hot air is sprayed to heat the adhesive applied to the sole surface from the side. The vibration mechanism includes a piston plate 8 horizontally installed inside the placement mold 5, which slides against the inner wall of the placement mold 5. A return spring 10 is fixedly installed between the upper surface of the piston plate 8 and the inner wall of the placement mold 5. The piston plate 8 is fixedly connected to the contact plate 7 via a connecting rod 9. An electromagnet 11 is fixedly installed on the lower surface, and the position of the electromagnet 11 corresponds to that of the permanent magnet 12 fixedly installed inside the mounting platform 6. The magnetic action between the electromagnet 11 and the permanent magnet 12 drives the piston plate 8 to slide up and down. A receiving metal sheet 13 is fixedly installed on the front side of the mold 5, and the receiving metal sheet 13 is in contact with the power supply metal sheet 14. The power supply metal sheet 14 is fixedly installed in the middle of the inner side of the conveying platform 3, and an alternating current flows through the power supply metal sheet 14. Air inlet pipes 15 connected to the interior of the mold 5 are fixedly installed on the left and right sides of the mold 5, and the air inlet pipes 15 are located below the piston plate 8. An exhaust pipe 16 is fixedly installed on the upper surface of the piston plate 8. The through holes 17 are connected to the interior of the mold 5, and the through holes 17 are evenly distributed at equal intervals.

[0023] After the mold 5 is moved into the drying chamber 2, the receiving metal plate 13 on the front side of the mold 5 contacts the power supply metal plate 14 on the inner side of the conveyor table 3. The alternating current generated by the power supply device flows into the receiving metal plate 13 through the power supply metal plate 14, and finally supplies power to the electromagnet 11 through the wire connected to the receiving metal plate 13. Since an alternating current is provided, the magnetic field of the electromagnet 11 changes periodically. This, in conjunction with the permanent magnet 12 on the inner side of the mounting platform 6, causes the piston plate 8 to move up and down. (The change in the magnetic field of the electromagnet 11 causes it to periodically change between attraction and repulsion with the permanent magnet 12, thus moving the piston plate 8.) (Up and down movement) When the piston plate 8 moves upward, the negative pressure draws hot air from the drying oven 2 into the space below the piston plate 8 inside the mold 5 through the air inlet pipe 15. When the piston plate 8 moves downward, the hot air below the piston plate 8 is discharged to the space above the piston plate 8 through the exhaust pipe 16 and finally sprayed out from the through hole 17. The hot air sprayed out from the through hole 17 heats the sole from the side, adapting to the irregular shape of the sole. During the up and down movement of the piston plate 8, the connecting rod 9 drives the contact plate 7 to move synchronously. The contact plate 7 pushes the sole to vibrate up and down, vibrating the activated glue into the grooves and gaps of the sole, improving the adhesion of the glue.

[0024] Example 3: Please refer to Figures 9-10 In order to extend the heat preservation effect on the sole of the shoe, this embodiment provides the following technical solution, which specifically discloses that: a strip magnetic block 19 is embedded in the inner side of the connecting rod 9, a limiting sleeve 18 is fixedly installed inside the upper end of the mold 5, and the connecting rod 9 and the limiting sleeve 18 are slidably connected through each other, and the limiting sleeve 18 is made of copper.

[0025] After the shoe soles are dried, mold 5 is placed on the right side of conveyor table 3. The worker removes mold 5 from mounting table 6. Once mold 5 is removed, permanent magnet 12 loses its attraction to electromagnet 11 (electromagnet 11 has a steel core; although it loses its magnetism when de-energized, it is still attracted downwards by the magnetism of permanent magnet 12, thus placing piston plate 8 at the lower end of mold 5). At this time, the return spring 10 pulls piston plate 8 upwards. Simultaneously, the strip magnet 19 embedded in connecting rod 9 moves within limiting sleeve 18, causing... Since the limiting sleeve 18 is made of copper, when the bar magnet 19 moves inside the limiting sleeve 18, the magnetic field around the bar magnet 19 moves relative to the inner wall of the limiting sleeve 18. According to Lenz's law, the direction of the magnetic field generated by the induced current always tries to cancel out the cause that caused its change. Therefore, the magnetic field generated by the eddy current will interact with the magnetic field of the bar magnet 19, generating a force that opposes the relative movement of the bar magnet 19, thereby slowing down the movement speed of the piston plate 8. Under the action of the piston plate 8, the hot air inside the mold 5 is slowly squeezed out from the through hole 17, and the residual hot air is used to extend the heat preservation time of the shoe sole.
