Description

Technical Field

[0001] The present invention belongs to the technical field of shoe drying, and specifically relates to a drying device for a shoe-making assembly line and a drying method thereof. Background Art

[0002] Currently, the heating and drying technology used for shoe-making usually involves heating and baking by irradiating with infrared lamp tubes. It belongs to a dry-baking heating method. However, due to the posture of the shoes when entering the baking device, the irradiation angles are usually different, resulting in uneven heating of different positions of the glue on the upper and sole of the shoes. The glue used for bonding the sole usually adopts chemical reaction glue. Such glue requires some solvents on its surface to volatilize after coating and achieve preliminary curing, and then the upper and sole are pressed together for further curing.

[0003] Therefore, it is necessary to develop a more advantageous fresh air drying and curing system. For example, the intelligent shoe dryer disclosed in the application number CN202310953750.X. Others form a U-shaped chain shape through the cooperation of a driven flywheel and a driving flywheel. This shape can form an enclosure, and an assembly space can be formed at the position of the enclosure. By installing a heating component and a blowing component in this assembly space, the heat source radiates outward from the middle part, and then cooperating with the blowing assembly to make the shoes heated evenly.

[0004] Although it overcomes some problems of traditional dry-baking drying, it is limited by its U-shaped movement trajectory, resulting in uneven hot air received by the shoe body when it reaches each position. And it cannot always ensure that all positions of the shoe body are heated evenly during the drying process.

[0005] Therefore, this application proposes a drying device for a shoe-making assembly line and a drying method thereof to overcome the above defects. Summary of the Invention

[0006] To solve the problems raised in the above background art, the present invention provides a drying device for a shoe-making assembly line and a drying method thereof.

[0007] To achieve the above object, the present invention provides the following technical solution: A drying device for a shoe-making assembly line includes a device body, and further includes a hot air blower, which is arranged in the middle of the inner cavity of the device body; an annular flow channel, which is arranged between the inner circumference of the device body and the outer circumference of the hot air blower; a fixture, placed on the annular flow channel for carrying the upper or sole; a hot air fan, which is arranged inside the hot air blower; the hot air blower includes an outer cover and an inner cover, and the outer cover and the inner cover enclose a hollow middle cavity for the hot air flow blown by the hot air fan to pass through; the inside of the device body is divided into upper and lower layers by a middle partition, and annular flow channels are arranged on both the upper and lower layers of the device body. The annular flow channels on the upper and lower layers are respectively slidably installed on the middle partition and the bottom plate of the device body; The annular flow channel includes a toothed ring, and a second drive machine is further arranged in the middle cavity of the hot air blower to drive the toothed ring to rotate; Temperature sensors are arranged in the upper and lower inner cavities of the equipment body.

[0008] Preferably, the annular flow channel further includes a carrier, a connecting column and a bottom support. The carrier and the bottom support are fixedly connected by the connecting column. The toothed ring is fixedly installed on the bottom support. The bottom of the bottom support is slidably installed on the middle partition or the bottom plate of the equipment body. A plurality of groups of arc-shaped through grooves are formed in the carrier.

[0009] Preferably, the fixture includes a base and a positioning block fixedly installed below the base. The positioning block is used for engaging with the arc-shaped through grooves arranged on the carrier. The base is an arc-shaped plate, and when the positioning block engages with the arc-shaped through grooves of the carrier, the center of the base coincides with the center of the carrier.

[0010] Preferably, the fixture further includes a heightening belt arranged at the bottom of the base, an outer clamping plate arranged on the outer peripheral side of the base, and an inner clamping plate detachably installed on the base; The arc-shaped passage formed between the inner clamping plate and the outer clamping plate is used for clamping the front face part of the shoe upper; A plurality of convex ribs are arranged on the inner peripheral side of the outer clamping plate.

[0011] Preferably, the hot air blower further includes an air duct I arranged in the middle cavity. The air duct I communicates the upper and lower inner cavities of the equipment body with the air inlet of the hot air blower; An air duct II is arranged at the bottom of the air duct I for guiding the pipeline between the air duct I and the hot air blower; Preferably, the hot air blower further includes a plurality of air outlets arranged at equal angles outside the outer cover. The air outlets of the air outlets communicate the inner cavity of the equipment body with the middle cavity of the hot air blower. The jet direction of the air outlets of the air outlets is tangent to the peripheral surface of the outer cover; The air outlets are arranged in both the upper and lower cavities of the equipment body.

[0012] Preferably, the hot air blower includes air outlets respectively guiding to the upper and lower cavities of the equipment body. Two throat pipes are arranged in the lower air outlet to reduce the width of the air outlet. A guide pipe communicating with the external environment is arranged in the middle of the air outlet. A valve plate is further arranged in the guide pipe to control the conduction area, and the guide pipe is driven to flip by a motor.

[0013] Preferably, two loading and unloading conveyor belts are arranged in the equipment body, which are respectively used for carrying the fixture in and out of the equipment body and falling on the annular flow channel. A tipping plate is arranged before the bottom end of the loading and unloading conveyor belt for transporting the fixture out. The tipping plate is fixedly installed on the hot air blower; The seesaw is used to lift the fixture.

[0014] Preferably, two conveying channels are arranged on the outer periphery of the equipment body to control the entry and exit of the shoe upper or sole into the inner cavity of the equipment body. Conveying rollers are arranged on the inner side of the conveying channels, and the conveying rollers are driven by a first driving machine installed outside the conveying channels.

[0015] A drying method for a shoe-making assembly line includes the following steps: Clamp the shoe upper on the fixture, and enter the fixture into the upper inner cavity of the equipment body through the conveying channel. As it circulates along the annular flow channel, and the sole is set to enter the lower inner cavity of the equipment body through the conveying channel; The hot air blower blows air into the upper and lower inner cavities of the equipment body. Since the inner cavity is in an annular configuration, the hot air flow circulates therein to heat and cure the shoe upper and sole in all directions; Measure the temperatures in the upper and lower layers through the temperature sensors arranged on the upper and lower layers of the equipment body to respectively adjust the temperatures therein to adapt to the glue on the cured sole and shoe upper.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, the shoe upper and sole are respectively conveyed to the upper and lower layers inside the equipment body through the conveying line. The glue on the shoe upper and sole is cured through the upper and lower conveying channels respectively. The conveying channel uses the rotating annular flow channel as the supporting platform. The annular flow channel is slidably installed on the middle partition and the equipment body. The toothed ring is arranged on the annular flow channel and is driven to rotate by a second driving machine. Through this annular cavity, it is easy to control the temperature and air flow direction therein, and it flows along the annular track over the shoe upper and sole to achieve uniform drying.

[0017] By setting the fixture, the arc-shaped roadway formed on the fixture clamps the shoe upper, and the fixture is concentric with the equipment body. On the one hand, it can adapt to the curvature of the shoe upper itself, so that the shoe upper body does not need to be deformed to have a curved arc. On the other hand, it can guide the direction to be the same as the track of the carrier and the track of the hot air, so that the obstruction to the propagation of the air flow is small, and it is also beneficial for the hot air flow to reach all parts of the shoe upper, and it always maintains the same angle with the air flow during the drying process. To achieve the purpose of uniform heating.

[0018] Two loading and unloading conveyor belts are respectively used to input or output the fixture from the inside. The loading and unloading conveyor belts generally have a certain curvature in the horizontal direction and the center of the circle coincides with the annular flow channel. Thus, the loading and unloading conveyor belt can accurately place the fixture on the annular flow channel, making the movement trend of the fixture in the horizontal direction consistent with the annular flow channel, avoiding large contact friction resulting in attitude problems and facilitating loading and unloading.

Specific embodiments

[0021] 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.

[0022] Such as Figures 1 to 7As shown in the figure, the present invention provides a drying device for a shoe-making assembly line and its drying method, including a device body 100, and further including a hot air blower 200, which is arranged in the middle of the inner cavity of the device body 100; a circular flow channel 300, which is arranged between the inner circumference of the device body 100 and the outer circumference of the hot air blower 200; a fixture 500, which is placed on the circular flow channel 300 for carrying the upper or sole; a hot air fan 600, which is arranged inside the hot air blower 200; the hot air blower 200 includes an outer cover 201 and an inner cover 202, and the outer cover 201 and the inner cover 202 enclose a hollow inner and outer sides and a middle cavity for the hot air flow blown in by the hot air fan 600 to pass through; the inside of the device body 100 is divided into upper and lower layers by a middle partition 102, and circular flow channels 300 are arranged on both the upper and lower layers of the device body 100, and the circular flow channels 300 on the upper and lower layers are respectively slidably installed on the middle partition 102 and the bottom plate of the device body 100; the circular flow channel 300 includes a toothed ring 304, and a second driving machine 700 is also arranged in the middle cavity of the hot air blower 200 for driving the toothed ring 304 to rotate; temperature sensors are arranged in the inner cavities of both the upper and lower layers of the device body 100.

[0023] The device is arranged on a glue bonding assembly line, and the upper and sole are respectively conveyed to the upper and lower layers inside the device body 100 through a conveyor line. The glue on the upper and sole is cured through the upper and lower conveying channels respectively. The conveying channel uses the rotating circular flow channel 300 as a supporting platform. The circular flow channel 300 is slidably installed on the middle partition 102 and the device body 100. The toothed ring 304 is arranged on the circular flow channel 300 and is driven to rotate by the second driving machine 700. Through this circular cavity, it is easy to control the temperature and air flow direction therein, and it flows along the circular track over the upper and sole to achieve uniform drying.

[0024] The hot air fan 600 is arranged in the center of the hot air blower 200, and the hot air blower 200 blows the hot air flow evenly into the drying channel formed between the device body 100 and the hot air blower 200 to form a circular hot air flow.

[0025] As Figure 5 and Figure 6 As shown in the figure, the circular flow channel 300 further includes a carrier 301, a connecting column 302 and a bottom support 303. The carrier 301 and the bottom support 303 are fixedly connected through the connecting column 302. The toothed ring 304 is fixedly installed on the bottom support 303. The bottom of the bottom support 303 is slidably installed on the middle partition 102 or the bottom plate of the device body 100. The carrier 301 is provided with a number of groups of arc-shaped through grooves.

[0026] The carrier 301 and the base 303 are connected by a connecting column 302 to form an annular platform, which is slidably mounted on the middle partition 102. The drive motor two 700 can drive the annular flow channel 300 to slide and rotate. The annular flow channel 300 is provided on both the upper and lower layers of the equipment body 100 and can be used to support the upper and sole respectively.

[0027] As Figure 8 shown, the fixture 500 includes a base 501 and a positioning block 503 fixedly installed below the base 501. The positioning block 503 is used to engage with the arc-shaped through groove provided on the carrier 301. The base 501 is an arc-shaped plate, and when the positioning block 503 is engaged with the arc-shaped through groove of the carrier 301, the center of the base 501 coincides with the center of the carrier 301.

[0028] Both the front and rear sides of the positioning block 503 below the base 501 are provided with arc-shaped transition surfaces. Therefore, when the carrier 301 drives the base 501 to rotate, it can be directly lifted up when encountering an obstacle. During the conveying process of the carrier 301, it can be lifted by a wedge-shaped seat provided by the suspension height at its end, so that it can smoothly reach other platforms or steps.

[0029] As Figure 7 and Figure 8 shown, the fixture 500 further includes a heightening belt 502 provided at the bottom of the base 501, an outer clamping plate 505 provided on the outer peripheral side of the base 501, and an inner clamping plate 504 detachably installed on the base 501; The arc-shaped lane formed between the inner clamping plate 504 and the outer clamping plate 505 is used to clamp the front face part of the upper; Several convex ribs are provided on the inner peripheral side of the outer clamping plate 505.

[0030] The inner clamping plate 504 is in an L-shaped configuration, and there are two waist-shaped holes provided thereon. The waist-shaped holes on the base 501 are assembled by bolt fasteners to adjust the assembly position between the bases 501 and clamp them according to the inclined plane height. The arc-shaped lane between the inner clamping plate 504 and the outer clamping plate 505 can adapt to the curvature of the bottom of the inclined plane. Therefore, the upper can be firmly clamped without forcibly deforming the upper during the clamping process.

[0031] The heightening belt 502 provided below the base 501 is used for heightening, so that the bottom of the base 501 will not be closely attached to the carrier 301, which is convenient for taking out.

[0032] The convex ribs provided on the inner side of the outer clamping plate 505 are used to reduce the contact area with the bottom of the upper, and the formed gap can allow hot air flow to pass through, so that the bottom of the upper is heated evenly. Convex ribs can also be provided on the contact surface of the inner clamping plate 504 with the upper. The reason and principle are the same, so they are not shown in the figure. Those skilled in the art can make flexible adjustments, which can be achieved without creative labor.

[0033] In addition, it should be noted that the sole does not need to be conveyed by the fixture 500. It can be directly placed on the conveying roller 401 and conveyed in.

[0034] As Figures 3 to 5 shown, the hot air blower 200 further includes an air duct 203 disposed in the middle cavity. The air duct 203 connects the upper and lower inner cavities of the equipment body 100 and the air inlet of the hot air blower 600; The bottom of the air duct 203 is provided with an air duct 204 for guiding the pipeline between the air duct 203 and the hot air blower 600.

[0035] This embodiment is a preferred embodiment for realizing the hot air flow circulation in the present application. The air duct 203 connects the upper and lower two-layer annular hot air flow spaces between the equipment body 100 and the hot air blower 200, and then is diverted to the air inlet of the hot air blower 600 through the air duct 204. A heating component is provided at the air inlet of the hot air blower 600. This heating component is located in Figure 5 the air inlet pipe of which is not shown in the figure. When the air flow passes through, it is circularly heated. Therefore, the air flow can be continuously circularly heated according to the different required ambient temperatures until the ambient temperature reaches the standard, and then the heating duration per unit time of the heating component is adjusted for heat preservation, or the heating work is turned off.

[0036] As Figure 3 shown, the hot air blower 200 further includes a plurality of air outlets 205 arranged at equal angles outside the outer cover 201. The air outlet of the air outlet 205 communicates with the inner cavity of the equipment body 100 and the middle cavity of the hot air blower 200. The jet direction of the air outlet of the air outlet 205 is tangent to the circumferential surface of the outer cover 201; The air outlets 205 are provided in both the upper and lower two-layer cavities of the equipment body 100.

[0037] By making the opening of the air outlet 205 point to the tangent direction of the outer cover 201, the hot air flow ejected therefrom can form an annular air flow between the equipment body 100 and the hot air blower 200. The direction of this annular air flow is opposite to the conveying direction of the fixture 500. The back opening of the shoe upper on the fixture 500 is opposite to the hot air flow direction. The hot air flow can directly blow into it, and then the same temperature is generated at the insole of the shoe and the glue application area on the outside of the inclined surface. The glue application area of the shoe upper is sandwiched between the inner clamping plate 504 and the outer clamping plate 505. The air flow passes through the glue application area and is heated in cooperation with the insole area. Therefore, the entire shoe upper can be uniformly heated.

[0038] As Figure 4 and Figure 5As shown in the figure, the hot air blower 600 includes air outlets that respectively guide air into the upper and lower cavities of the equipment body 100. Among them, two throat pipes 601 are arranged in the lower air outlet to reduce the width of the air outlet. A gas guide pipe 602 communicating with the external environment is arranged in the middle of the air outlet. A valve plate is also arranged in the gas guide pipe 602 to control the conduction area, and the gas guide pipe 602 is driven by a motor to flip.

[0039] The throat pipe 601 is the contraction section of the air outlet of the hot air blower 600. It speeds up the flow rate here by reducing the cross-sectional area, forming a strong low-pressure area. Therefore, it can suck up the low-temperature gas in the external environment through the pressure difference and mix it with the hot air therein, reducing the temperature of the hot air.

[0040] A valve plate 603 is arranged in the gas guide pipe 602. The main function of the valve plate 603 is to control the air intake volume of the gas guide pipe 602. When it is necessary to adjust the air intake volume here, it can be directly driven by a motor to deflect and adjust. The deflection angle is determined according to the temperature difference between the actual temperature and the preset temperature in the second-layer cavity.

[0041] When the actual temperature is lower than the preset temperature, the valve plate 603 closes and cuts off the gas guide pipe 602. When the actual temperature is higher than the preset temperature, the valve plate 603 conducts the gas guide pipe 602, and the low-temperature air flow in the external environment enters the throat pipe 601 due to the pressure difference and mixes with the high-temperature air flow, reducing the air flow temperature. Thus, the temperature of the lower-layer environment is reduced.

[0042] Temperature sensors are arranged in both the upper and lower layers of the equipment body 100 to detect the real-time temperature in the corresponding environment. The temperature signal is sent to the controller for real-time scanning and comparison to judge the difference. According to this logic, it is judged whether the valve plate 603 should be opened or the opening amplitude.

[0043] As Figure 3 As shown in the figure, two loading and unloading conveyor belts 101 are arranged in the equipment body 100, which are respectively used to carry the fixture 500 in and out of the interior of the equipment body 100 and place it on the annular flow path 300. A tipping plate 103 is arranged before the bottom end of the loading and unloading conveyor belt 101 for transporting the fixture 500. The tipping plate 103 is fixedly installed on the hot air blower 200; The tipping plate 103 is used to lift the fixture 500.

[0044] The tipping plate 103 is wedge-shaped, and its tip is in the direction of the fixture 500 turning. The heightening belt 502 arranged at the bottom of the fixture 500 straddles the carrier 301, lifting the whole fixture 500 upward. Therefore, the front end of the tipping plate 103 can extend under the base 501 to lift the fixture 500 transported by it upward. The fixture 500 can be transported onto the tipping plate 103 and then reach the loading and unloading conveyor belt 101 and be output from the equipment body 100 along with it.

[0045] The two loading and unloading conveyor belts 101 are respectively used to input or output the fixture 500 from the inside. The loading and unloading conveyor belts 101 generally have a certain curvature in the horizontal direction and coincide with the annular flow channel 300 in terms of the center of the circle. Thus, the loading and unloading conveyor belts 101 can accurately place the fixture 500 on the annular flow channel 300, making the movement trend of the fixture 500 in the horizontal direction consistent with that of the annular flow channel 300, and avoiding incorrect postures caused by large frictional resistance.

[0046] As Figure 1 shown, two conveying channels 400 are provided on the outer periphery of the equipment body 100 to control the entry and exit of the shoe upper or sole into and out of the inner cavity of the equipment body 100. A conveying roller 401 is provided inside the conveying channel 400, and the conveying roller 401 is driven by a first driving machine 402 installed outside the conveying channel 400.

[0047] The conveying rollers 401 are arranged at both ends of the inlet and outlet. Placing the sole and the shoe upper on the conveying rollers 401 can convey them inward onto the carrier 301. The sole and the shoe upper are conveyed in two upper and lower layers respectively. When the shoe upper is conveyed in the upper layer, the loading and unloading conveyor belts 101 are used. When the upper layer is also used to convey the sole, the conveying rollers 401 are also used for conveying.

[0048] The upper and lower layers of conveying rollers 401 on the same side are driven by the same motor. Wind curtains can be set at the inlets and outlets of the conveying channels 400 according to actual needs to reduce the leakage of hot air flow therein.

[0049] The working principle and usage process of the present invention: Clamp the shoe upper on the fixture 500, and enter the fixture 500 into the upper inner cavity of the equipment body 100 through the conveying channel. As the annular flow channel 300 circulates annularly, while the sole is arranged to enter the lower inner cavity of the equipment body 100 through the conveying channel; The hot air blower 600 blows air into the upper and lower inner cavities of the equipment body 100. Since the inner cavity is of an annular configuration, the hot air flow circulates annularly therein to heat and cure the shoe upper and the sole in all directions of 360°; Measure the temperatures in the upper and lower layers through the temperature sensors provided in the upper and lower layers of the equipment body 100, and respectively adjust the temperatures therein to adapt to the glue for curing the sole and the shoe upper.

[0050] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0051] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
