Description

Technical Field

[0001] This utility model relates to the field of printing and dyeing equipment technology, specifically to an automatic steaming box. Background Technology

[0002] In the dyeing and printing process, steam treatment is a crucial step affecting the dyeing quality and production efficiency of sample fabrics. The steaming effect of the sample fabric directly determines its color uniformity, stability, and suitability for subsequent processing. Currently, the traditional steaming boxes widely used in the industry mostly adopt an integrated door and manual operation structure. Operators need to manually open the door to take out and put in the sample fabric. This operation method has significant technical defects: On the one hand, when the integrated door is opened, the high-temperature steam inside the box leaks out rapidly, and a large amount of ambient air rushes in, causing a sharp fluctuation in the temperature field inside the box. This results in an unstable temperature environment during the dyeing process of the sample fabric, causing serious color difference problems and affecting the consistency of product quality. On the other hand, traditional steaming boxes rely on independent timers, requiring operators to be on duty throughout the process to control the timing of sample fabric removal. This not only consumes a lot of labor costs and reduces production efficiency, but also makes it easy for the sample fabric to not be taken out in time due to unexpected situations such as operators being busy, resulting in over-steaming. This causes the sample fabric color to become unstable, requiring the entire process to be reprocessed, which not only wastes raw materials such as dyes, but also further increases production time and labor input, making it difficult to meet the actual technical requirements of the dyeing and printing industry for processing precision, efficiency, and cost control. Summary of the Invention

[0003] The purpose of this utility model is to provide an automatic steam chamber. The steam chamber divides the steam chamber into sections through heat insulation plates, avoiding steam leakage and cold air influx when the traditional integrated door is opened. This significantly reduces the temperature fluctuation range inside the steam chamber. Furthermore, the timer and displacement component of the control device are electrically connected to realize the full automation of the "timing-drive-picking and placing" process, reducing labor costs and avoiding excessive steaming due to human negligence, thus reducing dye waste and time spent on repeated processing.

[0004] This utility model is achieved through the following technical solution: An automatic steam oven, comprising: The box body has a steaming chamber inside for steaming the sample cloth; A heat insulation plate is hinged to the top of the steaming chamber and divides the steaming chamber into two independent areas, an inner and an outer one. A displacement component is provided between the side walls of the two areas, and the displacement component drives the tray to reciprocate between the two areas. A control device, comprising a timer electrically connected to the displacement assembly.

[0005] In this solution, a heat insulation plate is hinged to the top of the steaming chamber and divides it into two independent inner and outer areas. This effectively avoids the problem of rapid leakage of high-temperature steam and large influx of ambient air when the traditional integrated door is opened. It significantly reduces the fluctuation of the temperature field inside the steaming chamber and ensures the stability of the temperature environment during the sample dyeing process. At the same time, the timer and displacement component of the control device are electrically connected, realizing the full automation of the "timing-drive-removal" process of the sample. There is no need for operators to be on duty throughout the process to control the timing of sample removal. This reduces labor costs, improves production efficiency, and avoids the phenomenon of excessive steaming of sample due to unexpected situations such as busy operators. It also reduces the waste of raw materials such as dyes and the additional production time and labor input caused by repeated processing.

[0006] As a further embodiment of the automatic steam oven, the displacement component includes rollers and a drive component. Multiple sets of rollers are evenly arrayed along the movement direction of the tray. Each roller is matched and connected to the corresponding drive component and rotates synchronously. By providing a uniform and continuous driving force to the tray, the movement speed of the tray is ensured to be stable and controllable, which not only improves the smoothness and reliability of automated picking and placing, but also reduces the frictional wear between the tray and related components.

[0007] As a further solution for the automatic steam oven, the roller and the bottom wall of the tray are meshed and driven. By forming a precise and stable power transmission relationship, the problems of slippage and displacement deviation that may occur in traditional transmission methods are effectively avoided, ensuring the positional accuracy and motion synchronization of the tray when it reciprocates between the two independent areas inside and outside the steam cavity.

[0008] As a further embodiment of the automatic steam oven, the displacement component also includes a sliding component. The sliding component includes a slide rail located between the side walls of the steam chamber. A slide groove is provided in the middle of the slide rail. Slider blocks matching the slide groove are provided on both sides of the tray. By forming a guide and limiting structure, the lateral displacement of the tray during the reciprocating motion can be effectively limited, ensuring that the tray always moves smoothly along the preset trajectory.

[0009] As a further embodiment of the automatic steam oven, the bottom wall of the slide is provided with an array of rolling grooves, and each rolling groove is connected to a non-powered rolling column. The slider makes rolling contact with the rolling column, which effectively converts the sliding friction between the slider and the slide into rolling friction, thus greatly reducing the frictional resistance during the reciprocating motion of the tray.

[0010] As a further embodiment of the automatic steaming chamber, the tray is provided with a bearing cavity for holding the sample fabric. The bearing cavity has a hollow structure, which improves the uniformity and thoroughness of the steaming reaction, thereby optimizing the dyeing effect of the sample fabric.

[0011] As a further solution for the automatic steam oven, the heat insulation plate is made of high-temperature resistant heat insulation material, which can further enhance the zoned heat insulation effect of the steam cavity and effectively block the heat from the inner high-temperature steam zone from being transferred to the outer area.

[0012] As a further improvement to the automatic steam oven, the insulation board is made of a flexible material, which allows it to fit more closely with the steam chamber and the edge of the tray, further reducing the leakage of high-temperature steam between the two independent areas and enhancing the heat insulation effect.

[0013] As a further embodiment of the automatic steam oven, an insulated door is hinged to the outside of the oven body. The insulated door is correspondingly located to the outer area of ​​the steam chamber. The insulated door and the oven body are opened and closed by a switch assembly, which facilitates the operator to quickly open and close the door before and after taking out or placing the sample fabric.

[0014] As a further embodiment of the automatic steam oven, the switch assembly is an electromagnetic lock structure. Both the drive assembly and the switch assembly are electrically connected to the timer. Automated linkage control is achieved through the electrical connection between the timer and both. When the preset steaming time is reached, the timer can simultaneously trigger the electromagnetic lock to unlock and the drive assembly to start, so that the heat preservation door opens automatically and the tray moves out smoothly.

[0015] Compared with the prior art, this utility model has the following advantages and beneficial effects: 1. This utility model uses a heat insulation plate hinged to the top of the steam chamber and divided into two independent areas. Combined with the heat insulation door on the outside of the chamber, it forms a double-sealed heat insulation structure, which effectively avoids the problem of high-temperature steam leakage and outside room temperature air rushing in when the traditional integrated door is opened, and greatly reduces the temperature field fluctuation amplitude in the steam chamber. 2. In this utility model, the timer of the control device is electrically connected to the displacement component and the switch component of the electromagnetic lock structure, forming a fully automated linkage of "timing-unlocking-driving-picking and placing". This eliminates the need for operators to monitor and control the timing of picking and placing the sample fabric throughout the process, thereby reducing manpower input and avoiding timing deviations caused by manual operation, and significantly improving production efficiency.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model. Example 1

[0019] This embodiment 1 provides an automatic steam oven, such as Figures 1-2 As shown, it includes a housing 2, a heat insulation board 5, and a control device 4; Among them, such as Figure 1 As shown, the housing 2 serves as the main load-bearing structure of the equipment, with a pre-reserved sealed steaming chamber inside to provide a stable high-temperature environment for the steaming of the sample fabric. An insulated door 1 is hinged to the outside of the housing 2, corresponding to the outer area of ​​the steaming chamber. A high-temperature resistant sealing gasket is attached to the inner side of the insulated door 1 to ensure a tight seal after closure. Simultaneously, a switch assembly 6 is fixedly installed at the closure point of the housing 2 and the insulated door 1. This assembly uses an electromagnetic lock structure and is electrically connected to the control device 4 to achieve automated opening and closing control of the insulated door 1. Figure 2 As shown, the heat insulation plate 5 is hinged to the inner top of the steaming chamber, with the hinge shaft positioned along the width of the steaming chamber. This allows the heat insulation plate 5 to rotate flexibly around the hinge shaft, thus dividing the steaming chamber into an inner high-temperature steaming zone and an outer transitional loading / unloading zone. The two zones are independent of each other and are connected only through the movement channel of the tray 9. The control device 4 is embedded in the outer wall of the housing 2, and its surface integrates operation buttons and a display device 3. Internally, it integrates a timer and a drive control module, providing the control core for the automated operation of the equipment.

[0020] Please refer to Figures 3-5A displacement assembly is also provided between the side walls of the steam chamber. The displacement assembly extends along the movement direction of the tray 9. The tray 9 is connected to the displacement assembly and can reciprocate between the high-temperature steam zone and the transition pick-and-place zone along a preset trajectory under the drive of the displacement assembly. Specifically, the displacement assembly includes rollers 7 and drive assembly 84. Multiple sets of rollers 7 are evenly arranged in an array along the movement direction of the tray 9. The two ends of each set of rollers 7 are rotatably connected to the two side walls of the steam chamber through bearing seats. The axis of the rollers 7 is perpendicular to the movement direction of the tray 9. One end of each roller 7 extends into the side wall of the box (2) and is connected to the corresponding drive assembly 84 through a coupling. The drive assembly 84 adopts a micro stepper motor, and all drive assemblies 84 are electrically connected to the drive control module of the control device 4 to ensure that multiple sets of rollers 7 rotate synchronously. In this embodiment, to avoid slippage and displacement deviation during movement, the outer peripheral surface of the roller 7 is machined with a toothed structure, and the bottom wall of the tray 9 is correspondingly provided with a matching toothed groove. The roller 7 and the tray 9 are meshed and driven through the toothed structure and the toothed groove.

[0021] More specifically, in some embodiments, such as Figure 6 and Figure 7 As shown, the displacement assembly also includes a sliding assembly 8, which includes a slide rail 81, a slide groove 82, a rolling column 83, and a rolling groove 85. The slide rail 81 is a long strip structure and is fixed to the two side walls along the length of the steaming chamber. A slide groove 82 is formed in the middle of the slide rail 81 along its length, and the cross-section of the slide groove 82 is U-shaped. The two side walls of the tray 9 are integrally formed with sliders 91. The cross-sectional shape of the sliders 91 is adapted to the slide groove 82, and the sliders 91 are embedded in the slide groove 82 to form a sliding fit, thereby achieving lateral positioning of the tray 9.

[0022] To reduce the motion resistance between the slider 91 and the groove 82, multiple rolling grooves 85 are arranged in an array along the length of the bottom wall of the groove 82. Each rolling groove 85 is rotatably connected to a non-powered rolling column 83 through a rotating shaft. The top of the rolling column 83 protrudes from the groove opening of the rolling groove 85 and makes rolling contact with the bottom wall of the slider 91, thus converting the sliding friction between the slider 91 and the groove 82 into rolling friction. Example 2

[0023] This embodiment 2 is based on the scheme of embodiment 1, the difference being that the heat insulation plate 5 is made of a composite of high-temperature heat-resistant insulation material and flexible substrate, such as a fiberglass cloth reinforced silicone rubber composite plate or a flexible mica sheet composite silicone plate. When the heat insulation plate 5 is in a vertically closed state, the heat insulation plate 5 is in contact with the side wall of the steam chamber and the upper surface of the tray 9, ensuring the sealing of the high-temperature steam zone. When the tray 9 moves outward, the top edge of the tray 9 can lift the heat insulation plate 5 and rotate it around the hinge axis to open the channel. After the tray 9 is fully inserted into the high-temperature steam zone, the heat insulation plate 5 resets and closes under its own gravity, achieving partition isolation again. Among them, the tray 9 is made of lightweight high-temperature resistant plastic integral injection molding, and its bearing cavity 10 has a hollow structure, with the hollow holes evenly distributed on the bottom wall and side wall of the bearing cavity 10, ensuring that high-temperature steam can penetrate the sample cloth in all directions without dead angles, improving the uniformity of steaming.

[0024] Meanwhile, the timer of the control device 4 can be preset with the operation button to control the steaming time. The timer is electrically connected to the drive component 84 and the switch component 6 to form an automated linkage control logic: when the operator puts the sample cloth into the bearing cavity 10 of the tray 9 and closes the heat insulation door 1, the switch component 6 triggers a closing signal. After receiving the signal, the control device 4 starts the drive component 84, which drives the tray 9 to carry the sample cloth into the high-temperature steaming area. At the same time, the heat insulation plate 5 resets and closes, and the equipment begins to perform steaming operations according to the preset time. When the preset steaming time is reached, the timer sends an end signal. The control device 4 first controls the switch component 6 to unlock, and the heat insulation door 1 automatically opens to a certain angle under the elasticity of the hinge. Then the drive component 84 rotates in reverse, and the tray 9 carries the sample cloth to the transition pick-and-place area, completing the automated pick-and-place process.

[0025] Workflow: The operator opens the insulation door 1, places the sample cloth to be steamed flat into the bearing cavity 10 of the tray 9, closes the insulation door 1, and the switch assembly 6 automatically locks and sends a signal to the control device 4.

[0026] The steaming time is preset by the operation button of the control device 4, and the preset parameters are displayed synchronously by the display device 3. After the equipment is started, the control device 4 drives the drive component 84 to operate, the roller 7 rotates synchronously and drives the tray 9 to move to the high temperature steaming zone through meshing transmission. The top edge of the tray 9 lifts the heat insulation plate 5 and flips it. After entering the high temperature steaming zone, the heat insulation plate 5 resets and closes, and the equipment starts steaming operation.

[0027] During the steaming process, the display device 3 displays the remaining steaming time and the temperature inside the cavity in real time. The heat insulation plate 5 and the heat preservation door 1 work together to ensure the temperature stability of the high-temperature steaming zone and prevent heat loss.

[0028] After the preset steaming time is reached, the control device 4 controls the switch assembly 6 to unlock, the heat preservation door 1 opens automatically, and at the same time the drive assembly 84 rotates in reverse, moving the tray 9 out to the transition pick-up and drop area. The operator takes out the sample cloth and completes one steaming operation.

It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
