Description

Technical Field

[0001] This invention relates to the field of screen printing technology, and in particular to a screen printing production line. Background Technology

[0002] Screen printing is a long-established and widely used printing process. Its basic principle is to use a screen printing plate with a perforated pattern, where ink is transferred through the mesh to the surface of the substrate under the pressure of a squeegee, thus forming the desired image or text. Due to its relatively simple equipment structure, strong adaptability, thick ink layer, and good adhesion, screen printing is widely used in the manufacture of functional products such as electronic components (e.g., solar cells, touch screen electrodes), labels, packaging materials, textiles, and flexible films.

[0003] In continuous screen printing production of long ribbons, effective fixation is usually required to ensure the ribbon's stable position and prevent shifting or slippage during the printing process. Currently, the most common fixation method in the industry is to use a perforated conveyor belt in conjunction with a negative pressure adsorption system: the ribbon is laid flat on the surface of a conveyor belt with micropores or through-holes, and a sealed cavity is set under the conveyor belt and connected to a vacuum source. The negative pressure adsorbs and adheres the ribbon to the conveyor surface, thereby achieving precise positioning and stable transport during printing, drying, and other processes.

[0004] However, when this negative pressure adsorption solution is actually applied to ribbon printing, the diversity of ribbon materials and structures directly affects the adsorption effect: especially high elasticity, porous or mesh structure ribbons, which are breathable or elastic, make it difficult for negative pressure to form an effective seal on their surface, resulting in insufficient adsorption force and inability to fix stably. Meanwhile, the conventional driving method of existing conveyor belts, namely continuous traction by rollers at both ends, also has inherent limitations: the conveyor belt is prone to slippage during long-term operation, which can lead to deviations in the conveying position of the webbing. To address these issues, the inventors have proposed a screen printing production line to solve the aforementioned technical problems. Summary of the Invention

[0005] The objective of this invention is achieved through the following means: a screen printing production line, comprising a base and a conveyor belt, wherein the base is provided with printing units and an intermediate oven, the printing units are distributed at both ends of the base, the intermediate oven is disposed between the printing units, the printing units and the oven are disposed on the base along the same axis, the conveyor belt is disposed on the top surface of the base, and the conveyor belt passes through the processing areas of the printing units and the intermediate oven in sequence, a finished product oven is provided on one side of the base, the working surface of the conveyor belt is coated with self-adhesive, and an adjustable pressure roller is provided at the end of the base away from the finished product oven, wherein the webbing is bonded to the self-adhesive on the conveyor belt by the pressure roller during feeding; The top surface of the machine base near the finished product oven is equipped with a traction component for driving the conveyor belt.

The movable seat is movably mounted on the linear transmission mechanism, and its top surface is in contact with the non-working surface of the conveyor belt. On both sides above the conveyor belt near the movable seat, there are clamping blocks that can move up and down. When the clamping blocks are pressed down, they clamp the two sides of the conveyor belt and drive the conveyor belt to move synchronously when the movable seat moves. A rotatable peeling roller shaft is located on the machine base near the finished product oven. The peeling roller shaft has a square structure.

[0007] In a further embodiment of the above description, a rotating frame is provided between the discharge port of the intermediate oven and the printing unit. The top of the rotating frame extends directly upward toward the machine base. Both ends of the bottom of the rotating frame are provided with rotatable first reversing rollers, and the top of the rotating frame is provided with rotatable second reversing rollers. Both ends of the middle part of the rotating frame are provided with support rods, which are fixedly connected to the rotating frame.

[0008] In a further embodiment of the above description, a feeding assembly is provided at the end of the machine base away from the finished product drying oven. The feeding assembly includes a mounting frame and a guide plate. The guide plate is distributed on the side of the pressure roller away from the machine base, and the mounting frame is distributed at both ends of the guide plate. The mounting frame is connected to the machine base. A loading shaft is provided at the end of the mounting frame away from the guide plate. A movable positioning sleeve is provided on the loading shaft. A fixed shaft is provided in the middle of the mounting frame near the loading shaft. Positioning rings aligned with the guide plate are distributed on the fixed shaft. A flat plate is provided in the middle of the mounting frame, and an adjustable pressure plate is provided above the flat plate.

[0009] In a further embodiment of the above description, a conveying roller is installed near the conveyor belt in the finished product drying oven. The conveying roller is flush with the working surface of the conveyor belt. The peeling roller is mounted on the machine base via a support frame. A drive motor is provided on one side of the support frame near the peeling roller. The output rod of the drive motor passes through the support frame and is connected to the peeling roller.

[0010] In a further embodiment of the above description, the finished product oven is provided with a receiving assembly on the side away from the machine base. The receiving assembly includes a mounting frame and a side frame. The mounting frame is located on the side of the finished product oven away from the machine base, and the side frame is located on the side of the mounting frame away from the finished product oven.

[0011] In a further embodiment of the above description, a rotatable transport shaft is provided on the mounting frame near the guide shaft, and a movable driven shaft is provided above the transport shaft.

A third reversing roller is provided on the top of the mounting frame near the transport shaft, and several guide rollers are arranged in the middle of the mounting frame.

[0012] Compared with the prior art, the beneficial effects of the present invention are: by coating the conveyor belt with self-adhesive and providing a pressure roller at the feeding end of the conveyor belt, the webbing will directly contact the self-adhesive on the conveyor belt under the action of the pressure roller when it is fed. This enables the self-adhesive to reliably adhere to the webbing with high elasticity, porous or mesh structure through surface adhesion force, without relying on air sealing or negative pressure. This avoids the situation where the negative pressure is difficult to form an effective seal on the surface when using vacuum adsorption, resulting in insufficient adsorption force and inability to fix stably. Meanwhile, this application provides a traction component at one end of the machine base near the finished product drying oven. When the clamping block presses down to lock the conveyor belt, the linear transmission mechanism drives the movable seat to move along the machine base axis, thereby driving the entire conveyor belt and the webbing attached to it to move synchronously. This structure realizes active and precise traction of the conveyor belt body, avoiding the conveying error caused by conveyor belt slippage in the traditional continuous roller drive method.

Detailed Implementation

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] For this embodiment, please refer to Figures 1-10The specific implementation of the screen printing production line includes a base 1 and a conveyor belt 16. The base 1 is provided with printing units 2 and intermediate oven 3. The printing units 2 are distributed at both ends of the base 1, and the intermediate oven 3 is arranged between the printing units 2. The printing units 2 and the oven are arranged on the base 1 along the same axis. The conveyor belt 16 is arranged on the top surface of the base 1 and passes through the processing areas of the printing units 2 and the intermediate oven 3 in sequence. A finished product oven 4 is provided on one side of the base 1. The working surface of the conveyor belt 16 is coated with self-adhesive. An adjustable pressure roller 601 is provided at the end of the base 1 away from the finished product oven 4. When the webbing is fed, it is bonded to the self-adhesive on the conveyor belt 16 through the pressure roller 601. A traction assembly 5 for driving the conveyor belt 16 is provided at one end of the top surface of the machine base 1 near the finished product oven 4. The traction assembly 5 includes a movable seat 501 and a linear transmission mechanism 502. The linear transmission mechanism 502 is located at one end of the top surface of the machine base 1 and is located between the top surface of the machine base 1 and the non-working surface of the conveyor belt 16. The movable seat 501 is movably mounted on the linear transmission mechanism 502, and the top surface of the movable seat 501 is in contact with the non-working surface of the conveyor belt 16. Clamping blocks 503 that can move up and down are provided on both sides of the upper part of the conveyor belt 16 near the movable seat 501. When the clamping blocks 503 are pressed down, they clamp the two sides of the conveyor belt 16 and drive the conveyor belt 16 to move synchronously when the movable seat 501 moves. A rotatable peeling roller shaft 8 is provided at one end of the machine base 1 near the finished product oven 4. The peeling roller shaft 8 has a square structure. By coating the conveyor belt 16 with self-adhesive, the self-adhesive can reliably adhere to highly elastic, porous or mesh-structured webbing through surface adhesion without relying on air seals or negative pressure. Specifically, when the webbing enters the conveyor belt 16 through the feeding component 6, the webbing will come into contact with the self-adhesive on the conveyor belt 16 and then adhere to the conveyor belt 16. The conveyor belt 16 then transports the webbing into the working area of ​​the printing unit 2 for printing. After printing, it is transported to the drying oven 4 to accelerate the solidification of the dye on the webbing. Finally, it enters the working area of ​​the flipping frame 9 for cooling and then is transported back to the working area of ​​the printing unit 2 for the next pattern or color printing operation.

[0016] A linkage block 504 is provided above the clamping block 503. The clamping block 503 is fixedly installed at both ends of the bottom surface of the linkage block 504. A mounting seat 505 is provided above the linkage block 504. A pressing cylinder 506 is provided on the top surface of the mounting seat 505. The push rod of the pressing cylinder 506 passes through the mounting seat 505 and connects to the top surface of the linkage block 504. The bottom surface of the mounting seat 505 is connected to the top surface of the movable seat 501. Specifically, during operation, the pressing cylinder 506 is activated, and the push rod drives the linkage block 504 and the clamping block 503 to move downward, so that the clamping block 503 and the movable seat 501 clamp the two sides of the conveyor belt 16. Then, the linear transmission mechanism 502 drives the movable seat 501 to move, so as to realize the traction of the conveyor belt 16 to move in segments. After completing a segment movement, the pressing cylinder 506 drives the linkage block 504 and the clamping block 503 to move upward, and the linear transmission mechanism 502 drives the movable seat 501 to reset, and the reciprocating operation is performed.

[0017] A flip frame 9 is provided between the discharge port of the intermediate oven 3 and the printing unit 2. The top of the flip frame 9 extends directly above the base 1. Both ends of the bottom of the flip frame 9 are provided with rotatable first reversing rollers 10. The top of the flip frame 9 is provided with rotatable second reversing rollers 11. Both ends of the middle part of the flip frame 9 are provided with support rods 12, which are fixedly connected to the flip frame 9. Specifically, after the webbing enters the working area of ​​the flipping frame 9, it changes direction by passing the first reversing roller 10 at one end and moves towards the second reversing roller 11. During this process, the webbing flips 180°. Then, after passing the second reversing roller 11, the webbing moves towards the first reversing roller 10 at the other end. Finally, it changes direction by passing the first reversing roller 10 at the other end and comes into contact with the self-adhesive on the conveyor belt 16 again, entering the working area of ​​the next printing unit 2 for a second printing operation.

[0018] The base 1 is provided with a feeding assembly 6 at the end away from the finished product drying oven 4. The feeding assembly 6 includes a fixed frame 602 and a guide plate 603. The guide plate 603 is distributed on the side of the pressure roller 601 away from the base 1. The fixed frame 602 is distributed at both ends of the guide plate 603. The fixed frame 602 is connected to the base 1. The fixed frame 602 is provided with a loading shaft 604 at the end away from the guide plate 603. The loading shaft 604 is provided with a movable positioning sleeve 605. The fixed frame 602 is provided with a fixed shaft 606 in the middle near the loading shaft 604. The fixed shaft 606 is provided with positioning rings 607 that are aligned with the guide plate 603. The fixed frame 602 is provided with a flat plate 608 in the middle. An adjustable pressure plate 609 is provided above the flat plate 608. Specifically, during feeding, the webbing is wrapped around the loading shaft 604 and positioned by the positioning sleeve 605. Then, the webbing is wrapped around the fixed shaft 606 and positioned by the positioning ring 607. After passing through the plate 608 and the pressure plate 609, it passes through the guide plate 603. Finally, under the action of the pressure roller 601, the webbing is pressed onto the conveyor belt 16 and adheres to the self-adhesive on the conveyor belt 16.

[0019] The finished product drying oven 4 is equipped with a conveyor roller 13 near the conveyor belt 16. The conveyor roller 13 is flush with the working surface of the conveyor belt 16. The peeling roller 8 is mounted on the machine base 1 through the support frame 14. A drive motor 15 is provided on one side of the support frame 14 near the peeling roller 8. The output rod of the drive motor 15 passes through the support frame 14 and is connected to the peeling roller 8. Specifically, by using a square peeling roller 8, when the peeling roller 8 rotates, it will lift the webbing that passes directly above the peeling roller 8 upwards, so that the webbing is separated from the self-adhesive on the conveyor belt 16, so that the webbing can continue to be transported into the finished product drying oven 4.

[0020] The finished product oven 4 is provided with a receiving assembly 7 on the side away from the base 1. The receiving assembly 7 includes a mounting frame 701602 and a side frame 702. The mounting frame 701 is located on the side of the finished product oven 4 away from the base 1, and the side frame 702 is located on the side of the mounting frame 701602 away from the finished product oven 4. The side frame 702 is connected to the mounting frame 701. The top of the side frame 702 is provided with a rotatable winding wheel 703, and the side frame 702 is provided with a guide shaft 704 on the side near the mounting frame 701.

[0021] The mounting frame 701 has a rotatable transport shaft 705 located near the guide shaft 704. Above the transport shaft 705 is a movable driven shaft 706, which is in contact with the transport shaft 705. Both ends of the driven shaft 706 are connected to the mounting frame 701 via a swing frame 707. The mounting frame 701 has swingable lifting cylinders 708 on both sides. The push rods of the lifting cylinders 708 are movably connected to the swing frame 707. The top of the mounting frame 701 is located near the transport shaft 705 and has a third reversing roller 709. Several guide rollers 7010 are arranged in the middle of the mounting frame 701.

[0022] Specifically, after the webbing comes out of the finished product oven 4, it moves toward the guide rollers 7010 distributed in the middle of the mounting frame 701, and after passing around multiple guide rollers 7010 in sequence, it moves to the transport shaft 705 through the third reversing roller 709, and finally is fixedly connected to the take-up wheel 703 through the guide shaft 704. The take-up wheel 703 rotates, and the webbing is pulled and wound around the take-up wheel 703.

[0023] The workflow of this application is as follows: The operator first places the webbing roll onto the loading shaft 604 and positions it using the positioning sleeve 605. At the same time, the operator threads the webbing onto the webbing roll and connects the webbing to the winding wheel 703. During operation, the printing section of the webbing passes around the fixed shaft 606 in sequence and is positioned by the positioning ring 607. After passing through the flat plate 608 and the pressure plate 609, it passes through the guide plate 603 and finally, under the action of the pressure roller 601, the webbing is pressed onto the conveyor belt 16 and adheres to the self-adhesive on the conveyor belt 16. Then, the pressing cylinder 506 is opened, and the push rod drives the linkage block 504 and the clamping block 503 to move down, so that the clamping block 503 and the movable seat 501 clamp the two sides of the conveyor belt 16. Then, the linear transmission mechanism 502 drives the movable seat 501 to move, thereby pulling the conveyor belt 16 to move in segments, and then driving the printing section into the working area of ​​the printing unit 2 to perform the printing process. After the printing is completed, the conveyor belt 16 continues to drive the printing section to enter the intermediate oven 3 for the printing coating curing operation. After the coating has cured, the printing section enters the working area of ​​the flipping frame 9, and after changing direction by the first reversing roller 10 at one end, it moves towards the second reversing roller 11 and rises to the second reversing roller 11. During this process, the webbing flips 180°, and after passing the second reversing roller 11, it moves towards the first reversing roller 10 at the other end. Finally, it changes direction by the first reversing roller 10 at the other end, re-contacts the self-adhesive on the conveyor belt 16, and is transported to the next printing unit 2 for a second printing operation. After the secondary printing operation is completed, the printing section is transported to the finished product drying oven 4 via conveyor belt 16 and dried in the finished product drying oven 4. Finally, after the webbing comes out of the finished product drying oven 4, it moves toward the guide rollers 7010 distributed in the middle of the mounting frame 701 and passes around multiple guide rollers 7010 and the third reversing roller 709 in sequence, presenting a reciprocating path between the upper and lower positions. Finally, it is transported between the transport shaft 705 and the driven shaft 706, and the guide shaft 704 is fixedly connected to the take-up wheel 703. The take-up wheel 703 rotates, pulling the webbing to wrap around the take-up wheel 703.
