[0025] According to the disclosed content of the present invention, the automatic continuous plate-making production line for screen printing stencils has the advantages of fully automated continuous production, multi-functional integration, high-precision control, high production efficiency, stable product quality, good equipment compatibility, perfect safety protection devices, convenient maintenance, energy conservation and environmental protection, and strong flexibility, etc., effectively solving the technical problems existing in the traditional plate-making process, such as cumbersome processes, dependence on manual operation, single equipment function, difficult to accurately control process parameters, low production efficiency, unstable product quality, poor equipment compatibility, lack of safety protection devices, and inconvenient maintenance, etc. This production line significantly improves production efficiency, reduces production costs, and improves product quality, meeting the requirements of the modern screen printing industry for high precision and high efficiency.

[0026] As Figures 2 - 7As shown in the figure, the buffer oven 10 includes a heat-insulating box body 1015. Inside the heat-insulating box body 1015, there is a main frame 1016. Inside the main frame 1016, there is a movable screen frame which includes multiple compartments; a heating component and a screen frame lateral movement component are arranged at the bottom of the main frame 1016, and the screen frame is installed on the screen frame lateral movement component; at the bottom of the main frame 1016, there is also a screen conveyor component opposite to the inlet and outlet of the heat-insulating box body 1015. The transmission direction of the screen conveyor component is perpendicular to the transmission direction of the screen frame lateral movement component, and the screen conveyor component is installed on a lifting device provided at its bottom.

[0027] In this actual example, an automatic screen conveyor, screen lateral movement, and internal automatic temperature control structure form are adopted, which improves the working efficiency of screen conveyor and taking out after drying. Through the buffer design of multiple compartments, pipeline operation is realized, reducing the downtime waiting time. Multiple compartments can be processed continuously, greatly increasing the number of screens processed per unit time compared with traditional equipment, thus improving the overall production efficiency.

[0028] The screen conveyor component includes a clamping plate type transmission frame. In the middle of the transmission frame, there is a buffer driving wheel 1010 driven by a reduction motor 109. On both sides of the buffer driving wheel 1010 on the transmission frame, there are buffer driven wheels 1011. A buffer chain 1014 is laid outside the buffer driving wheel 1010 and the buffer driven wheels 1011, and a guiding gear 1012 for pressing the buffer chain 1014 is arranged on the transmission frame.

[0029] On the transmission frame, there is also a buffer tensioning wheel 1013. The buffer tensioning wheel 1013 is arranged in the lateral adjustment groove of the transmission frame, and the buffer tensioning wheel 1013 is located outside the buffer chain 1014.

[0030] This component is mainly responsible for the screen conveyor work. The reduction motor 109 provides driving force for the buffer driving wheel 1010. The buffer driven wheels 1011 and the guiding wheels play a role in guiding the buffer chain 1014 to ensure the stable operation of the buffer chain 1014. The buffer tensioning wheel 1013 is used for the tensioning adjustment of this component to ensure the stability of the entire conveyor system. A supporting gear can also be arranged at the bottom to assist in lifting the buffer chain 1014.

[0031] When this component receives the start signal, the dried screen is accurately moved to directly above this component with the help of the screen frame lateral movement component. During this process, the lifting device (a cylinder is adopted in this actual example, but not limited to a cylinder) plays a role and lifts this component upward by jacking. After the jacking is in place, the motor starts to convey the screen through the sprocket buffer chain 1014 (but not limited to the sprocket buffer chain 1014), thus realizing the efficient and stable conveyance of the screen. With the coordinated cooperation of each component in the whole system, the screen conveyance task can be completed quickly and accurately, providing strong support for relevant production processes.

[0032] The lateral movement assembly of the screen frame includes two buffer synchronous wheels 106 relatively installed on the bottom crossbeam of the main frame 1016. A buffer drive belt 107 is provided on the two buffer synchronous wheels 106. The buffer synchronous wheels 106 are driven by a cross-movement motor 105. A screen frame connection plate 108 is clamped and fixed on the buffer drive belt 107. The other end of the screen frame connection plate 108 is fixed to the bottom of the screen frame. Pulley running along the crossbeam at the bottom of the main frame 1016 is provided at the bottom of the screen frame.

[0033] Specifically, corresponding buffer sensors are provided above the buffer synchronous wheels 106. The buffer sensors are arranged on the side of the crossbeam at the bottom of the main frame 1016. Two anti-collision devices are also relatively provided on the top of the crossbeam at the bottom of the main frame 1016. The buffer sensors here are limit buffer sensors, which ensure the maximum distance of the lateral movement of the screen frame. The anti-collision devices can prevent the screen frame from hitting the insulation box 1015 in case the buffer sensors fail, thus affecting the work progress.

[0034] Among them, a strip-shaped installation position is provided on the side of the crossbeam at the bottom of the main frame 1016, and the buffer sensors are arranged on the strip-shaped installation position. The strip-shaped installation position can adjust the position of the buffer sensors according to the actual lateral movement requirements to adapt to different external screen replenishment devices.

[0035] This part specifically undertakes the task of the lateral movement of the screen frame. Its power source is provided by the cross-movement motor 105. The cross-movement motor 105 can operate through shaft transmission (there may be other transmission methods in addition to shaft transmission), drive the buffer synchronous wheels 106 (not limited to the buffer synchronous wheels 106) by means of the rotation of the shaft, and then drive the screen frame connection plate 108 through the buffer drive belt 107, so that the screen frame can perform stable and repeated lateral movement within the installation range of the buffer sensors.

[0036] If the next process does not require a screen, the screen frame will automatically start the detection mechanism. At this time, the grid storing the dried screen will automatically move inside the screen conveying assembly, so as to smoothly convey the screen to the next process. It is worth mentioning that the screen frame has the ability to store multiple groups of screens and can be flexibly adjusted according to specific production requirements to meet different production scenarios and process requirements.

[0037] The heating assembly is arranged in a matrix on the bottom side of the main frame 1016. The heating assembly includes a rectangular frame surrounded by a shield 103. Heating tubes 101 are horizontally arranged inside the shield 103, and multiple fans 102 are provided on the side of the shield 103.

[0038] A flow dividing plate 104 is provided on the top of the rectangular frame surrounded by the shield 103. The flow dividing plate 104 has a number of pores, and the pores are arranged alternately and obliquely.

[0039] During the working process, the fan 102 plays a key role. It can effectively extract the air heated by the heating tube 101 to meet the requirement of the oven for rapid temperature rise. To ensure that the heated air can be evenly introduced into the interior of the oven, a flow distribution plate 104 is installed above the oven. Through this design, the heated air can enter the oven in a more uniform manner under the action of the flow distribution plate 104, thus avoiding the temperature difference inside the oven caused by uneven air flow, improving the uniformity and stability of the oven heating, and helping to improve the quality and efficiency of the entire drying process.

[0040] The screen frame includes an outer frame. The width of the outer frame is half of the width of the main frame 1016. Multiple grid compartments are formed inside the outer frame through partition frames, and the partition frames facing the inlet and outlet of the heat preservation box body 1015 are inclined inward.

[0041] Among them, an automatic door driven by a cylinder is provided on the front side of the heat preservation box body 1015, an exhaust gas discharge port is provided on the top, and an observation window is provided on the side.

[0042] In this embodiment, 10 grid compartments are provided. The screen is pushed into the grid compartments and carried into the heat preservation box body 1015 by the screen conveying assembly. The heat preservation box body 1015 is constructed by welding a stainless steel plate and a steel plate. This unique processing and installation method not only ensures the structural strength of the shell but also provides a solid foundation for laying heat preservation cotton inside. The heat preservation cotton laid inside (but not limited to this processing and installation method) can effectively prevent heat dissipation, thus ensuring that the oven has a good heat preservation effect and providing a stable temperature environment for the drying process.

[0043] Inside the heat preservation box body 1015, an advanced PID control system is installed. This system can monitor the internal temperature in real time and automatically adjust according to the set parameters, so that the internal temperature always remains within the ideal range without frequent manual intervention, improving the automation degree and stability of the drying process.

[0044] In addition, the heat preservation box body 1015 is also provided with an observation window and an exhaust gas discharge port. The observation window is convenient for the operator to observe the drying situation inside the oven at any time, adjust the drying parameters in time or handle abnormal situations. The exhaust gas discharge port is used to discharge the exhaust gas generated during the drying process to ensure the cleanliness and safety of the working environment.

[0045] The automatic door is driven by a cylinder and can be automatically opened and closed. During the drying process, the opening and closing actions of the automatic door can effectively reduce heat loss, improve the thermal efficiency of the oven, and reduce energy consumption. At the same time, the opening and closing process of the automatic door is stable and reliable, and it can avoid damaging the items inside the oven due to improper manual operation.

[0046] Such asFigures 8 - 12 As shown in the figure, it shows an automatic screen plate inspection table provided by an embodiment of the present utility model. It includes a frame, a screen plate lifting assembly disposed inside the frame, and a screen plate conveying assembly disposed at the bottom of the screen plate rack. The frame includes an inspection bottom. Screen plate conveying ports are provided on both sides of the inspection bottom frame 201. A backlight assembly 203 is provided on the back of the inspection bottom frame 201, and an inspection controller 205 is provided on the front side of the inspection bottom frame 201; the screen plate lifting assembly includes a screen plate rack opposite to the screen plate conveying port. The screen plate rack includes two frames disposed opposite to each other. A lifting device is provided at the top of the screen plate rack. The power end of the lifting device is disposed at the top of the inspection bottom frame 201, and the lifting end is connected to the top of the screen plate rack. Blocking assemblies are provided on the front and rear sides of the screen plate rack.

[0047] Through the automated conveying function, the cumbersome steps of manually carrying the screen plate to the bracket are avoided, significantly shortening the inspection time and improving the overall production efficiency.

[0048] Among them, a plurality of limiting mechanisms 204 are provided on the side of the screen plate conveying port of the inspection bottom frame 201. An auxiliary feeding pulley 202 is also provided on the screen plate conveying port, and the height of the auxiliary feeding pulley 202 is the same as the height of the screen plate conveying assembly.

[0049] In order to be able to repair the screen plate during the inspection process, an air gun is also provided on the front side of the inspection bottom frame 201. The air gun is powered by a gas pump disposed at the bottom of the inspection bottom frame 201.

[0050] The backlight assembly 203 consists of multiple (not limited to LED light strips) LED light strips working in cooperation with an acrylic plate, providing illumination by scattering light to meet relevant requirements. The frame is welded by stainless steel pipes (not limited to this processing method), providing a stable structure for the entire system to ensure the installation and operation of each component. The auxiliary feeding pulley 202 is used for connecting the front and rear end devices, and its function is to facilitate the smooth conveying of the screen plate and realize the material transfer between the front and rear end devices. The limiting mechanism 204 is used for limiting the movement of the screen plate rack, specifically divided into upper and lower limits and the height limit of the conveying position, accurately controlling the movement range of the screen plate rack, and ensuring the normal operation and positioning of the screen plate. The inspection controller 205 controls the movement of the device and the switch of the backlight assembly 203, and can precisely regulate the operating state of the entire system to achieve automated operation. The air gun is used for repairing unqualified screen plates. When the screen plate is unqualified, the air gun can quickly and accurately perform the repair operation, improving the production efficiency and product quality.

[0051] The lifting device includes a winding motor 206 installed at the center of the top of the inspection bottom frame 201. The driving end of the winding motor 206 is provided with a winding wire 207. The two ends of the winding wire 207 are respectively connected to the fixed nodes 2011 at both ends of the top of the screen plate rack through support pulleys 208.

[0052] Guide assemblies are provided on both sides of the screen frame, and the guide assemblies include a group of inspection rails 209 whose two ends are respectively fixed on the top and bottom of the inspection base frame 201, and the inspection rails 209 correspond to the two frames of the screen frame respectively. The top and bottom of the frame are provided with guide pulleys 2010 for limiting the inspection rails 209, wherein the guide pulleys 2010 are two opposite pulley assemblies, which clamp the inspection rails 209 to prevent them from falling out, thereby ensuring the stability of the up and down movement of the screen frame.

[0053] In order to ensure that the screen is lifted to the corresponding position, a sensor assembly is provided at the bottom of the screen frame, and the sensor assembly is displaced to the outside of the guide pulley 2010. A plurality of inspection guide rail 209 guard plates are provided on the screen frame, and the inspection guide rail 209 guard plates can prevent the inspection guide rail 209 from falling out due to external influences.

[0054] The blocking assembly includes a guardrail arranged at the rear side of the screen frame, and a tightening rope arranged at the front side of the screen frame. The tightening rope is clamped on a bolt body on the screen frame, and a tightening adjusting piece is provided on the tightening rope.

[0055] This part is mainly responsible for the important task of lifting the screen to meet the needs of large screens. The sensor component part is mainly used to detect the screen frame to ensure the stable conveying state of the screen during the equipment transportation process and avoid dangerous situations caused by the lifting of the screen frame. The twisting motor 206 plays a key role and is specifically used to drive the lifting action of the screen frame assembly. The twisting motor 206 and the twisted wire 207 are connected by a support pulley 208 to realize the lifting operation of the screen frame. At the same time, the guide pulley 2010 clamps, guides and tensions the inspection guide rail 209 to ensure the stability and accuracy of the lifting process. In addition, the existence of the blocking component ensures that the screen will not be separated from the equipment during the whole process, providing a strong guarantee for the safe operation of the screen.

[0056] The screen conveying assembly includes a driving motor installed on the outside of the screen frame, which drives the inspection driving wheel 2012 arranged between the two frames through the transmission shaft. The inspection driving wheel 2012 is connected to the inspection driven wheel 2014 located at the opposite end of the inspection driving wheel 2012 through the inspection transmission belt 2013. The inspection driven wheel 2014 is fixed on the adjusting part, which is a strip hole set on the frame, and can realize the tension adjustment of the inspection transmission belt 2013.

[0057] This part is mainly used for the transmission of the screen printing stencil. Among them, the drive motor motor assembly plays a key driving role, providing the power required for the transmission of the screen printing stencil. Under the mutual cooperation of the inspection driving wheel 2012 and the inspection driven wheel 2014, a collaborative working system is formed to jointly promote the smooth transportation of the screen printing stencil on a specific track or path. The adjusting part of the inspection driven wheel 2014 plays an important auxiliary role.
