Description

Technical Field

[0001] This invention belongs to the field of ironing equipment technology, and specifically relates to a garment ironing device. Background Technology

[0002] During the garment manufacturing process, fabrics often wrinkle, necessitating ironing to shape and reduce wrinkles. When using existing ironing equipment, garments are typically placed on a worktable and ironed using electric heating technology.

[0003] However, because it's difficult to control the movement speed and ironing pressure of garments, this can easily lead to damage, resulting in inconsistent quality even within the same batch. If garments become yellowed or scorched, existing ironing equipment cannot address the issue promptly, rendering the entire garment unusable and causing significant waste.

[0004] Therefore, there is an urgent need to develop a new type of garment ironing device that can immediately stop when garments are damaged by heat, in order to reduce the amount of garment material wasted. Summary of the Invention

[0005] To address the aforementioned technical problems, the present invention aims to provide a garment ironing device with a high degree of intelligence, capable of immediately stopping ironing when garments are scorched, protecting the remaining garment material, reducing material waste, and thus lowering production costs.

[0006] The technical solution adopted to solve the above-mentioned technical problems is as follows:

[0007] This invention discloses a garment ironing device having mutually perpendicular vertical directions, a first direction, and a second direction, comprising:

[0008] A belt conveyor mechanism, the conveying direction of which extends along a first direction;

[0009] A pressure roller assembly is disposed above the belt conveyor mechanism, the pressure roller assembly having a heated roller surface for ironing garments, the heated roller surface extending along a second direction;

[0010] A lifting drive assembly, the output end of which is connected to the pressure roller assembly, to drive the pressure roller assembly to move in the vertical direction;

[0011] A gas sensor is used to detect the concentration of irritating gas at the pressing surface of the heated roller;

[0012] A controller, which is electrically connected to the gas sensor and the lifting drive assembly respectively, is configured to control the lifting drive assembly to move the pressure roller assembly upward when the concentration of the irritant gas is greater than a set value.

[0013] The garment ironing device provided by this invention has at least the following beneficial effects: A belt conveyor mechanism is used to transport garment material along a first direction. When the garment material moves to a position directly below the pressure roller assembly, the pressure roller assembly irons the garment material. During the ironing process, a gas sensor is activated. When the garment material is scorched, irritating gas is generated. At this time, the gas sensor detects the concentration data of the irritating gas and sends it to the controller. The controller sends a control command to the lifting drive assembly based on the comparison result of the irritating gas concentration with a set value. When the concentration of the irritating gas exceeds the set value, the lifting drive assembly, under the control of the controller, drives the pressure roller assembly upward, causing the pressure roller assembly to move away from the garment material, ending the ironing work. This avoids the garment material being severely scorched or damaged, thus protecting the remaining garment material, reducing waste, and helping to reduce the cost of garment production for enterprises.

[0014] As a further improvement to the above technical solution, the pressure roller assembly includes a bracket and an ironing pressure roller, the ironing pressure roller extends along a second direction, the opposite ends of the ironing pressure roller are rotatably disposed on the bracket, and the outer peripheral surface of the ironing pressure roller is the heating roller pressing surface.

[0015] With this configuration, the ironing roller can rotate relative to the support around its own central axis. When the belt conveyor conveys the garment material along the first direction, the ironing roller can apply uniform rolling pressure to the garment material through the rotating heated roller surface. At the same time, it can perform uniform ironing treatment on the garment material through electrothermal effect, reducing wrinkles and lowering the chance of the garment material being damaged by heat.

[0016] As a further improvement to the above technical solution, the ironing roller is provided with a cavity, the cavity extends along the second direction and penetrates one end face of the ironing roller to form an air outlet, the gas sensor is disposed near the air outlet, the outer peripheral wall of the ironing roller is provided with a plurality of air inlets evenly arranged along the second direction, the plurality of air inlets are set as a group, and a plurality of groups of air inlets are provided along the circumference of the ironing roller, and all the air inlets are connected to the cavity.

[0017] With this setup, when the ironing roller presses and irons the garment material, the garment material will come into contact with the heated roller surface. If the garment material is scorched, the irritating gas will flow through the air inlet to the cavity of the ironing roller and out through the air outlet. By setting the air inlet, cavity, and air outlet on the ironing roller, the irritating gas generated during the scorching process can be effectively collected, so that the gas sensor can detect it accurately in real time, improve the detection accuracy of the gas sensor, and facilitate timely stopping of the ironing work.

[0018] As a further improvement to the above technical solution, any two adjacent sets of air inlets are staggered. This arrangement allows for more air inlets on the ironing roller, facilitating the collection of more irritating gases. This enables accurate detection and feedback on whether the garment material has been scorched, preventing the garment material from being further ironed and causing severe burn damage.

[0019] As a further improvement to the above technical solution, both ends of the ironing roller are mounted on the bracket via bearings. This arrangement reduces friction during rotation, allowing the ironing roller to rotate smoothly under the influence of the garment material.

[0020] As a further improvement to the above technical solution, the gas sensor is disposed within the cavity. This arrangement allows the gas sensor to more accurately detect the concentration of pungent odor at the heated roller surface, avoiding the reduction in detection accuracy due to the influence of the external atmosphere.

[0021] As a further improvement to the above technical solution, the garment ironing device also includes a cushioning component. The cushioning component extends vertically, with one end connected to the output end of the lifting drive component and the other end connected to the support frame. This configuration ensures that the cushioning component provides effective cushioning as the pressure roller assembly moves downwards and presses against the garment material, preventing the garment material from being damaged by the pressure roller assembly.

[0022] As a further improvement to the above technical solution, the buffer assembly includes a lifting seat and a spring member. The lifting seat is located above the bracket, and the spring member extends in the vertical direction. One end of the spring member is connected to the bracket, and the other end is connected to the lifting seat. The lifting seat is connected to the output end of the lifting drive assembly.

[0023] A spring is installed between the lifting seat and the pressure roller assembly. During the process of the lifting drive assembly driving the lifting seat and the pressure roller assembly to move downward, the heated roller surface of the pressure roller assembly will roll and press the garment material. At this time, the spring can play a certain buffering role to prevent the garment material from being crushed due to excessive pressure. In addition, it can also promote the smooth linear movement of the garment material relative to the pressure roller assembly under the action of the belt conveyor mechanism, thereby preventing the garment material from being unable to move due to excessive pressure from the pressure roller assembly, which would cause the same position of the garment material to be heated for a long time and cause high temperature scorching.

[0024] As a further improvement to the above technical solution, the buffer assembly further includes a guide shaft extending in the vertical direction. One end of the guide shaft is connected to the bracket, and the other end is slidably connected to the lifting seat. The spring is sleeved on the guide shaft. The guide shaft enables the pressure roller assembly to move linearly relative to the lifting seat in the vertical direction, improving the smoothness of the pressure roller assembly's movement.

[0025] As a further improvement to the above technical solution, the lifting drive component is a telescopic cylinder, the belt conveyor mechanism is provided with a support frame, the telescopic cylinder is mounted on the support frame, and the movable rod of the telescopic cylinder is connected to the pressure roller assembly. The support frame on the belt conveyor mechanism provides support for the telescopic cylinder, and when the telescopic cylinder is working, the movable rod of the telescopic cylinder can drive the pressure roller assembly to rise and fall.

[0037] Reference Figures 1 to 4 Several embodiments of the garment ironing apparatus of the present invention are given below.

[0038] like Figures 1 to 4As shown, Embodiment 1 of the present invention provides a garment ironing device. This garment ironing device has the advantages of simple structure, ingenious design, and high degree of intelligence. The garment ironing device can immediately stop the machine and stop the ironing work when the garment is scorched, thereby protecting the remaining garment material to be ironed and preventing the garment material under ironing from being severely scorched or even burned. This can reduce the amount of waste in the use of garment materials, improve the safety of garment production, and effectively reduce the production costs of garment enterprises.

[0039] This garment ironing device has a first direction, a second direction, and a vertical direction. The first direction is perpendicular to the vertical direction, the second direction is perpendicular to the vertical direction, and the first direction is perpendicular to the second direction. In this embodiment, the first direction is assumed to be the front-back direction, and the second direction is assumed to be the left-right direction.

[0040] The garment ironing device includes a belt conveyor mechanism 100, a pressure roller assembly 400, a lifting drive assembly, a gas sensor 500, and a controller.

[0041] The conveying direction of the belt conveyor mechanism 100 extends along the first direction.

[0042] Specifically, the belt conveyor mechanism 100 includes a conveyor belt 110, a conveyor roller 140, a drive motor 120, and a base frame 130.

[0043] The base frame 130 provides support for the conveyor rollers 140 and the drive motor 120. There are at least two conveyor rollers 140, each extending along a second direction. All conveyor rollers 140 are arranged at certain intervals along a first direction and mounted on the base frame 130 via bearing seats, allowing the conveyor rollers 140 to rotate relative to the base frame 130. A conveyor belt 110 is wound around all the conveyor rollers 140. As the conveyor rollers 140 rotate, the conveyor belt 110 operates, conveying the garment material along the first direction.

[0044] The drive motor 120 is bolted to the base frame 130. The output shaft of the drive motor 120 is connected to one of the conveyor rollers 140 via a coupling, gear transmission structure, or belt transmission structure. Any two adjacent conveyor rollers 140 can be connected by a belt or chain. Therefore, when the drive motor 120 is working, all the conveyor rollers 140 rotate, thereby enabling the conveyor belt 110 to run and transport the garment material from front to back.

[0045] It is understandable that the left and right dimensions of the conveyor belt 110 can be set according to the actual situation, as long as the left and right dimensions of the conveyor belt 110 are greater than the left and right dimensions of the clothing material.

[0046] The pressure roller assembly 400 is disposed above the belt conveyor mechanism 100. In this embodiment, the pressure roller assembly 400 is located at the center of the belt conveyor mechanism 100 in a first direction. The pressure roller assembly 400 has a heated roller surface, which is used for ironing clothing materials, and the length direction of the heated roller surface extends along a second direction. Viewed along the second direction, the heated roller surface is circular.

[0047] The output end of the lifting drive component is fixedly connected to the pressure roller assembly 400. When the lifting drive component is activated, the output end of the lifting drive component will drive the pressure roller assembly 400 to move in the vertical direction, thereby adjusting the height position of the pressure roller assembly 400 relative to the garment material.

[0048] Understandably, the pressure roller assembly 400 moves upward under the driving action of the lifting drive assembly, increasing the vertical distance between the pressure roller assembly 400 and the garment material, thereby stopping the ironing work; the pressure roller assembly 400 moves downward under the driving action of the lifting drive assembly and comes into contact with the garment material in order to perform roller pressing and ironing.

[0049] The gas sensor 500 is used to detect the concentration of irritating gases produced by the clothing material at the heated roller pressing surface.

[0050] It is understandable that when clothing materials are scorched, they will produce irritating gases, such as sulfur dioxide. Therefore, the gas sensor 500 can be a sulfur dioxide gas sensor 500, which can accurately detect the concentration of sulfur dioxide gas.

[0051] The controller is electrically connected to the lifting drive assembly and the gas sensor 500 via wires. The controller is configured to control the lifting drive assembly to move the pressure roller assembly 400 upward when the concentration of the irritant gas exceeds a set value.

[0052] It is understood that the controller can be a PLC controller, a microcontroller, etc., and no specific limitation is made here. The controller can receive concentration data collected by the gas sensor 500, and the controller can send control commands to the lifting drive component. The concentration setpoint of the irritant gas can be set according to the actual situation, and no specific limitation is made here.

[0053] In using the garment ironing apparatus of this embodiment, the belt conveyor 100 can transport the garment material along a first direction, allowing the garment material to pass smoothly through the channel jointly defined by the pressure roller assembly 400 and the belt conveyor 100. When the garment material moves to a position directly below the pressure roller assembly 400, the upper surface of the garment material will come into contact with the heated roller pressing surface, causing the pressure roller assembly 400 to perform ironing treatment on the garment material.

[0054] During the ironing process, the gas sensor 500 is in operation, collecting real-time data on the concentration of irritating gases generated at the heated roller surface. When the garment material becomes scorched, irritating gases are produced. At this time, the gas sensor 500 detects the concentration data of the irritating gases and sends it to the controller. The controller can then send control commands to the lifting drive assembly based on the comparison between the concentration of the irritating gases and the set value.

[0055] If the concentration of the irritating gas does not exceed the set value, the lifting drive assembly remains stationary, without driving the pressure roller assembly 400 to move upwards or downwards. If the concentration of the irritating gas exceeds the set value, the lifting drive assembly will operate under the control of the controller, driving the pressure roller assembly 400 upwards. This causes the pressure roller assembly 400 to move away from the garment material, separating the garment material from the heated roller surface and immediately ending the ironing process. This avoids severely scorching the garment material or damaging the garment material to be ironed, effectively protecting subsequent garment materials to be ironed, reducing material waste, and helping to lower the cost of garment production for enterprises.

[0056] Of course, the controller can also be electrically connected to the belt conveyor mechanism 100. When the clothing material is scorched, the controller can not only control the lifting drive component to drive the pressure roller assembly 400 to move upward, but also control the belt conveyor mechanism 100 to stop running and stop the conveying of clothing material.

[0057] In some embodiments, such as Figures 1 to 4 As shown, the lifting drive component is a telescopic cylinder 200. The belt conveyor mechanism 100 is provided with a support frame 700, and the telescopic cylinder 200 is bolted to the support frame 700. The movable rod of the telescopic cylinder 200 is fixedly connected to the pressure roller assembly 400.

[0058] In this embodiment, the support frame 700 can be bolted to the base frame 130. The support frame 700 is located above the conveyor belt 110 and can be a U-shaped gantry frame. The telescopic cylinder 200 is located on the upper surface of the support frame 700, and the pressure roller assembly 400 is located below the telescopic cylinder 200. It is understood that the support frame 700 on the belt conveyor mechanism 100 provides support for the telescopic cylinder 200. When the telescopic cylinder 200 is working, its movable rod can drive the pressure roller assembly 400 to rise and fall. When the movable rod of the telescopic cylinder 200 retracts, the telescopic cylinder 200 drives the pressure roller assembly 400 to move upward; when the movable rod of the telescopic cylinder 200 extends, the telescopic cylinder 200 drives the pressure roller assembly 400 to move downward.

[0059] Of course, it cannot be ruled out that the lifting drive component may use linear modules, lead screw motors, or other linear drive devices.

[0060] In some embodiments, such as Figures 1 to 4 As shown, the pressure roller assembly 400 includes an ironing pressure roller 410 and a support 420. Viewed along a first direction, the support 420 can be a U-shaped plate. The ironing pressure roller 410 extends along a second direction, with its opposite ends positioned on the support 420. Furthermore, the ironing pressure roller 410 is capable of rotating relative to the support 420 around its central axis. The outer circumferential surface of the ironing pressure roller 410 is a heated pressing surface.

[0061] It is understandable that the ironing roller 410 can rotate relative to the support 420 around its own central axis. Therefore, when the belt conveyor mechanism 100 conveys the garment material along the first direction, the ironing roller 410 can apply uniform rolling pressure to the garment material through the rotating heated roller surface, and at the same time, it can perform uniform ironing treatment on the garment material through the electric heating effect, reduce the wrinkles of the garment material, and reduce the probability of the garment material being damaged by the heat.

[0062] In this embodiment, the ironing roller 410 has two opposite ends designated as rotating ends 413. The diameter of the rotating ends 413 is smaller than the diameter of the heating roller pressing surface. The rotating ends 413 are equipped with bearings, which are mounted on the bracket 420. This arrangement reduces the friction of the ironing roller 410 during rotation, allowing the ironing roller 410 to rotate smoothly under the influence of the clothing material.

[0063] In some embodiments, such as Figures 1 to 4 As shown, the ironing roller 410 has a hollow cavity 414 inside. The cavity 414 extends along the second direction in its length direction, and it penetrates one end face of the ironing roller 410, thereby forming an air vent 412. That is, the end face of one rotating end 413 of the ironing roller 410 is provided with an air vent 412, and the air vent 412 communicates with the cavity 414.

[0064] Furthermore, the ironing roller 410 is provided with air inlets 411. Specifically, multiple air inlets 411 are provided on the outer peripheral wall of the ironing roller 410. These multiple air inlets 411 are evenly arranged along the second direction of the ironing roller 410, forming a group. Multiple groups of air inlets 411 are arranged along the circumference of the ironing roller 410, and all air inlets 411 are connected to the cavity 414. A gas sensor 500 is positioned near the air outlet 412, and the gas sensor 500 can detect the concentration of irritating gas at the air outlet 412 in real time.

[0065] In this embodiment, the cavity 414 is a cylindrical cavity, and the air inlet 411 and the air outlet 412 are both round holes.

[0066] It is understandable that when the ironing roller 410 rolls and irons the garment material, the garment material will come into contact with the heated roller surface. If the garment material is scorched, the irritating gas will flow through the air inlet 411 to the cavity 414 of the ironing roller 410 and out through the air outlet 412. By setting the air inlet 411, cavity 414 and air outlet 412 on the ironing roller 410, the irritating gas generated during the scorching process can be effectively collected so that the gas sensor 500 can detect it accurately in real time, improve the detection accuracy of the gas sensor 500, and facilitate timely stopping of the ironing work.

[0067] In some embodiments, all the air inlets 411 are arranged in an array.

[0068] In other embodiments, such as Figure 3 As shown, any two adjacent sets of air intake holes 411 are staggered. Specifically, taking two sets of air intake holes 411 as an example, one set of air intake holes 411 is defined as the first air intake hole 411, and all the first air intake holes 411 are arranged at certain intervals along the second direction. The other set of air intake holes 411 is defined as the second air intake hole 411, and all the second air intake holes 411 are arranged at certain intervals along the second direction. A second air intake hole 411 is provided between any two first air intake holes 411, and the second air intake hole 411 is located in the middle of the two first air intake holes 411.

[0069] Understandably, by adopting the above-mentioned setting method, the setting distance between the two sets of air inlets 411 can be reduced. Therefore, more air inlets 411 can be set on the ironing roller 410 to collect more irritating gases, thereby accurately detecting and providing feedback on whether the clothing material has been scorched, and avoiding the problem of serious burn damage caused by the clothing material continuing to be ironed.

[0070] In some embodiments, such as Figure 1 and Figure 2 As shown, the gas sensor 500 is disposed outside the cavity 414 of the ironing roller 410. Specifically, the gas sensor 500 can be fixed to the support frame 700 by means of a mounting bracket, or it can be fixed to the rotating end 413 of the ironing roller 410.

[0071] In some embodiments, the gas sensor 500 is disposed within the cavity 414 of the ironing roller 410. Specifically, when the size of the air outlet 412 is sufficient to accommodate the gas sensor 500, the gas sensor 500 can be disposed within the air outlet 412. Alternatively, the gas sensor 500 can be disposed within the cavity 414. In this case, the wires of the gas sensor 500 are routed through the air outlet 412.

[0072] Understandably, when the gas sensor 500 is disposed within the cavity 414, the ironing roller 410 includes a cylindrical tube and end caps. End caps are provided at opposite ends of the tube, and the end caps can be connected to the tube by screws. The rotating end 413 is cylindrical and fixedly connected to the end caps, such as by welding. Therefore, after removing the end caps, the gas sensor 500 can be installed and removed from the cavity 414 of the ironing roller 410.

[0073] By adopting the above-described structural configuration, the gas sensor 500 can more accurately detect the concentration of irritating odors at the heated roller surface, and the detection accuracy of the gas sensor 500 can be prevented from being reduced by the influence of the external atmosphere.

[0074] The outer peripheral surface of the ironing roller 410 is provided with a heating element, and the outer peripheral surface of the rotating end 413 of the ironing roller 410 is provided with a wiring hole. The wiring hole is connected to the air outlet 412, and the wire of the heating element can be routed through the wiring hole and the air outlet 412.

[0075] In some embodiments, such as Figure 1 and Figure 2 As shown, the garment ironing device also includes a cushioning component. The cushioning component extends vertically, with one end fixedly connected to the output end of the lifting drive component and the other end fixedly connected to the bracket 420. Therefore, as the pressure roller assembly 400 moves downwards and presses against the garment material, the cushioning component provides effective cushioning, preventing the garment material from being damaged by the pressure roller assembly 400.

[0076] Specifically, the buffer assembly includes a spring element 600 and a lifting seat 300. The lifting seat 300 is positioned above the bracket 420. The spring element 600 extends vertically, with one end fixedly connected to the bracket 420 and the other end fixedly connected to the lifting seat 300. The lifting seat 300 is fixedly connected to the output end of the lifting drive assembly.

[0077] It is understandable that the number of spring components 600 can be set according to actual conditions, and is not limited to one or two. During the process of the lifting drive assembly driving the lifting seat 300 and the pressure roller assembly 400 to move downward, the heated roller surface of the pressure roller assembly 400 will roll the garment material. At this time, the spring component 600 can play a certain buffering role to prevent the garment material from being crushed due to excessive pressure. Moreover, it can also promote the smooth linear movement of the garment material relative to the pressure roller assembly 400 under the action of the belt conveyor mechanism 100, thereby preventing the garment material from being unable to move due to excessive pressure from the pressure roller assembly 400, which would cause the same position of the garment material to be heated for a long time and cause high temperature scorching.

[0078] Furthermore, the buffer assembly also includes a guide shaft 800. The guide shaft 800 extends vertically along its length. One end of the guide shaft 800 is fixedly connected to the bracket 420, and the other end is slidably connected to the lifting seat 300. Specifically, the lifting seat 300 may be equipped with a guide sleeve, the upper end of the guide shaft 800 passes through the guide sleeve, and a spring 600 is sleeved on the guide shaft 800. This arrangement allows the pressure roller assembly 400 to move linearly relative to the lifting seat 300 in the vertical direction, improving the smoothness of the pressure roller assembly 400's movement.

[0079] In other embodiments, the inner wall of the air outlet 412 of the ironing roller 410 is provided with a swirl vane to quickly expel the gas in the cavity 414. Thus, during the rotation of the ironing roller 410, the generated irritating gas can flow quickly into the cavity 414 through the air inlet 411 and flow quickly out from the air outlet 412, thereby increasing the gas flow rate. This allows the gas sensor 500 to quickly detect if the clothing material is scorched, facilitating rapid control to stop the ironing operation and preventing gas from accumulating in the cavity 414 for a long time.

[0080] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
