Description

Technical Field

[0001] This disclosure relates to the field of screen printing drying equipment technology, specifically to a buffer drying oven. Background Technology

[0002] The information disclosed in this background section is intended only to enhance understanding of the overall background of this disclosure and is not necessarily an admission or implication in any way that such information constitutes related technology that is already known to those skilled in the art.

[0003] In the traditional screen printing industry, the drying process has historically relied primarily on independent ovens. However, existing independent ovens have significant shortcomings. They lack the ability to automatically integrate with upstream and downstream processes, resulting in discontinuities in the production flow and hindering close coordination between different steps, thus greatly impacting production efficiency. Furthermore, the inability to continuously dry multiple screens necessitates frequent oven switching when dealing with a large volume of screen printing tasks, further reducing efficiency. Simultaneously, these ovens cannot precisely control process parameters during drying, failing to guarantee that each screen print is under optimal temperature and humidity conditions. This poses a serious threat to the quality stability of screen prints, easily leading to significant quality variations between batches and failing to meet the demands of high-quality screen printing production.

[0041] The following specific embodiments illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0042] The terms “upper,” “lower,” “left,” “right,” and “middle” used in this specification are merely for clarity of description and are not intended to limit the scope of this disclosure. Any changes or adjustments to their relative relationships, without substantially altering the technical content, shall also be considered within the scope of this disclosure.

[0043] like Figure 1 The diagram illustrates a buffer oven provided in an embodiment of the present invention. It includes an insulated chamber 401, inside which is a main frame 405. Inside the main frame 405 is a movable screen rack, which includes multiple compartments. A heating assembly and a screen rack lateral movement assembly are located at the bottom of the main frame 405, with the screen rack mounted on the lateral movement assembly. The bottom of the main frame 405 also has a screen conveying assembly opposite to the inlet and outlet of the insulated chamber 401. The transmission direction of the screen conveying assembly is perpendicular to the transmission direction of the lateral movement assembly, and the screen conveying assembly is mounted on a lifting device at its bottom.

[0044] In this example, the use of an automated screen conveyor, lateral screen movement, and internal automatic temperature control improves the efficiency of screen 601 conveying and post-drying removal. The multi-grid buffer design enables assembly line operation, reducing downtime. Multiple grids can process continuously, significantly increasing the number of screens 601 processed per unit time compared to traditional equipment, thereby improving overall production efficiency.

[0045] like Figure 2 As shown, the screen conveying assembly includes a clamp-type transmission frame 307. A drive gear 302 driven by a reduction motor 301 is provided in the middle of the transmission frame 307. Driven gears 303 are provided on both sides of the drive gear 302 on the transmission frame 307. A chain 306 is laid outside the drive gear 302 and the driven gears 303. A guide gear 304 for pressing the chain 306 is provided on the transmission frame 307.

[0046] Furthermore, the transmission frame 307 is also provided with a tension gear 305, which is located in the transverse adjustment groove of the transmission frame 307 and is located on the outside of the chain 306.

[0047] This component is mainly responsible for conveying the screen 601. The geared motor 301 provides driving force to the drive gear 302, while the driven gear 303 and guide wheel guide the chain 306 to ensure its smooth operation. The tension gear 305 is used for tension adjustment of this component to ensure the stability of the entire conveying system. A support gear can also be installed at the bottom to assist in lifting the chain 306.

[0048] Upon receiving the start signal, the dried screen 601 is precisely moved to a position directly above the component using the screen frame lateral movement component. During this process, the lifting device (in this example, a cylinder is used, but not limited to a cylinder) functions, lifting the component upwards. Once in position, the motor begins conveying the screen 601 via sprockets and chains 306 (but not limited to sprockets and chains 306), thus achieving efficient and stable conveying of the screen 601. With the coordinated operation of all components, the entire system can quickly and accurately complete the conveying task of the screen 601, providing strong support for related production processes.

[0049] like Figure 3-5 The transverse movement assembly of the screen frame includes two synchronous wheels 202 mounted on the bottom crossbeam of the main frame 405. The two synchronous wheels 202 are equipped with a transmission belt 203. The synchronous wheels 202 are driven by a transverse motor 201. The transmission belt 203 is equipped with a screen frame connecting plate 204 that is clamped and fixed. The other end of the screen frame connecting plate 204 is fixed to the bottom of the screen frame. The bottom of the screen frame is equipped with a pulley 205 that runs along the crossbeam at the bottom of the main frame 405.

[0050] Specifically, each synchronous pulley 202 is equipped with a corresponding sensor 206. The sensor 206 is located on the side of the crossbeam at the bottom of the main frame 405. Two anti-collision devices 207 are also provided on the top of the crossbeam at the bottom of the main frame 405. The sensor 206 here is a limit sensor, which ensures the maximum lateral distance of the screen frame. The anti-collision device 207 can prevent the screen frame from hitting the insulation box 401 and causing accidents in the event of sensor 206 failure, thus affecting the work progress.

[0051] The main frame 405 has a strip mounting position 208 on the side of the crossbeam at the bottom, and the sensor 206 is mounted on the strip mounting position 208. The strip mounting position 208 can adjust the position of the sensor 206 according to the actual lateral movement requirements to accommodate different supplementary equipment of the external mesh plate 601.

[0052] This part is specifically responsible for the lateral movement of the screen printing frame. Its power source is provided by the lateral movement motor 201, which can operate through shaft transmission (other transmission methods may also exist besides shaft transmission). The rotation of the shaft drives the synchronous pulley 202 (not limited to the synchronous pulley 202), which in turn drives the screen printing frame connecting plate 204 through the transmission belt 203. This allows the screen printing frame to perform stable and repeated lateral movement within the installation range of the sensor 206.

[0053] If the next process does not require screen printing plate 601, the screen printing plate rack will automatically activate its detection mechanism. At this time, the compartment containing the dried screen printing plate 601 will automatically move into the screen printing plate conveyor assembly, thus smoothly conveying the screen printing plate 601 to the next process. It is worth mentioning that the screen printing plate rack has the capacity to store multiple sets of screen printing plates 601 and can be flexibly adjusted according to specific production needs to meet different production scenarios and process requirements.

[0054] like Figure 6 As shown, the heating components are arranged in a matrix on the bottom side of the main frame 405. The heating components include a rectangular frame enclosed by a protective cover 103. Heating tubes 101 are arranged horizontally inside the protective cover 103, and multiple fans 102 are provided on the side of the protective cover 103.

[0055] Furthermore, a diversion plate 104 is provided on the top of the rectangular frame formed by the protective cover 103. The diversion plate 104 has a number of holes, which are arranged at alternating inclinations.

[0056] During operation, the fan 102 plays a crucial role, effectively drawing out the air heated by the heating tube 101 to meet the oven's rapid temperature rise requirement. To ensure that the heated air is evenly introduced into the oven, a flow divider 104 is installed above the oven. This design allows the heated air to enter the oven more evenly under the action of the flow divider 104, thus avoiding temperature differences inside the oven caused by uneven airflow, improving the uniformity and stability of heating, and contributing to the overall quality and efficiency of the drying process.

[0057] See you again Figure 3 The screen frame includes an outer frame 501, the width of which is half the width of the main frame 405. The interior of the outer frame 501 is divided into multiple compartments by partitions 502, which are inclined inward toward the inlet and outlet of the insulated box 401.

[0058] The insulated box 401 has an automatic door 404 driven by a cylinder on the front, an exhaust port 402 on the top, and an observation window 403 on the side.

[0059] In this embodiment, 10 grids are provided. The screen 601 is pushed into the grids and carried into the insulated chamber 401 by the screen conveyor assembly. The insulated chamber 401 is constructed by welding stainless steel plates together. This unique processing and installation method not only ensures the structural strength of the shell but also provides a solid foundation for the internal insulation cotton. The internal insulation cotton (but not limited to this processing and installation method) can effectively prevent heat loss, thereby ensuring that the oven has a good insulation effect and providing a stable temperature environment for the drying process.

[0060] An advanced PID control system is installed inside the insulated chamber 401. This system can monitor the internal temperature in real time and automatically adjust it according to the set parameters, so that the internal temperature is always kept within the ideal range without frequent manual intervention, thus improving the automation and stability of the drying process.

[0061] In addition, the insulated chamber 401 is also equipped with an observation window 403 and an exhaust port 402. The observation window 403 allows operators to observe the drying process inside the oven at any time, and adjust drying parameters or handle abnormal situations in a timely manner. The exhaust port 402 is used to discharge the exhaust gas generated during the drying process, ensuring a clean and safe working environment.

[0062] The automatic door 404 is driven by a cylinder, enabling it to open and close automatically. During the drying process, the opening and closing of the automatic door 404 effectively reduces heat loss, improves the thermal efficiency of the oven, and lowers energy consumption. At the same time, the opening and closing process of the automatic door 404 is smooth and reliable, preventing damage to items inside the oven due to improper manual operation.

[0063] Although the present disclosure has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, such modifications or improvements made without departing from the spirit of the present disclosure are all within the scope of protection claimed by the present disclosure.
