Description

Technical Field

[0001] This utility model relates to the technical field of louver processing equipment, specifically a louver blade processing device. Background Technology

[0002] Venetian blinds are a type of window shading device consisting of multiple parallel blades (mostly made of metal, wood, PVC, etc.). The blades are connected by a frame and can be flexibly rotated to adjust the angle. They can control the amount of light entering, ventilation, and privacy protection according to needs. Their structural design has practical functions such as sunshade, heat insulation, and wind protection, and they are widely used in homes, offices, and commercial spaces.

[0003] The blades of venetian blinds include flat and curved types. The traditional processing method for curved blades is to first cut the blade material into a specified size and then shape the cut blades. This processing method makes the processing efficiency of curved blades low and requires separate cutting and shaping equipment.

[0004] Therefore, we need to propose a louver blade processing device. Utility Model Content

[0005] The purpose of this utility model is to provide a louver blade processing device that eliminates the equipment switching time for cutting and forming in traditional processing, shortens the processing cycle of a single blade, and eliminates the need for two separate machines, saving space and costs, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A louver blade processing device, including: A base platform is provided with a conveying roller for conveying blade plates. A notch is provided at one end of the base platform, and a processing table is provided on one side of the notch. The processing mechanism is set on the base platform. The processing mechanism includes a first support plate and a first lifting seat. The first lifting seat is located inside the first lifting plate and is driven to lift by a hydraulic cylinder at the top of the first support plate. A blade and a forming strip are installed at the bottom of the first lifting seat. After the blade cuts the blade, the forming strip shapes the blade.

[0007] Preferably, the processing table and the top of the conveying roller are flush. The top of the processing table is provided with a cutting groove and a corresponding blade. The top of the processing table is provided with an inclined surface on one side of the cutting groove, which is inclined towards the notch. A forming groove is provided on the inclined surface. The forming groove and the forming strip are adapted to each other. A container is placed below the notch. After cutting and forming, the blade falls along the inclined surface into the container below the notch for collection.

[0008] Preferably, it also includes several sets of limiting posts, which are disposed on the top of the forming strip, and the top of the limiting posts is provided with a connecting rod.

[0009] Preferably, it also includes a cavity, which is formed inside the first lifting seat. Several cavities are provided inside one side of the first lifting seat. The connecting rod is slidably inserted into the bottom of the first lifting seat, and the upper end of the connecting rod extends into the cavity and is connected to a slider. The slider and the cavity are slidably engaged. A compression spring is provided inside the cavity between the slider and the top of the cavity. Under normal conditions, the lower end of the forming strip is 1-2cm lower than the lower end of the blade. During cutting, the forming strip first contacts the plate, and then the blade cuts. The forming strip presses the cut blade against the inclined surface. The connecting rod continues to retract into the cavity until the limiting post touches the bottom surface of the first lifting seat, so that the forming strip presses the blade into the forming groove to achieve the forming purpose. After the formed blade is reset by the first lifting seat, it slides down the inclined surface.

[0010] Preferably, it further includes a positioning mechanism disposed on the base. The positioning mechanism is located on one side of the processing mechanism. The positioning mechanism includes a second support plate and a second lifting seat. The second lifting seat is located inside the second support plate. An electric push rod for driving the second lifting seat is installed on the top of the second support plate.

[0011] Preferably, the bottom of the second lifting seat is provided with a pressure plate, and several sets of rubber positioning strips are evenly distributed at the bottom of the pressure plate. The positioning strips correspond one-to-one with the rollers of the conveying roller below. When processing the sheet material, the pressure plate descends, causing the positioning strips to abut against the top surface of the sheet material and press the sheet material tightly onto the conveying roller to prevent the sheet material from shifting.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The blade and forming strip of the processing mechanism are integrated on the same lifting seat and driven synchronously by the hydraulic cylinder to realize the continuous operation of "cutting-forming" of the blade plate. This eliminates the equipment switching time for cutting and forming in traditional processing, shortens the processing cycle of a single blade, and eliminates the need to set up two separate machines, saving space and costs. 2. The conveyor roller automatically conveys the sheet material, and the pressure plate of the positioning mechanism presses the sheet material tightly through the rubber positioning strip to prevent displacement during processing; the processed blades automatically slide down the inclined plane to the container below the notch, realizing the automation of "feeding-processing-collection" and reducing manual intervention.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 This utility model provides a technical solution: A louver blade processing device, including: A base 1 is provided with a conveying roller 2 for conveying blade plates. A notch 15 is provided at one end of the base 1, and a processing table 11 is provided on one side of the notch 15. The base 1 provides support for the entire device. The conveyor roller 2 continuously transports the blade sheet to the processing area by rotating. The processing table 11 is flush with the top of the conveyor roller 2 to ensure a smooth transition of the sheet. The notch 15 at one end of the base 1 matches the inclined surface 13 of the processing table 11, allowing the processed blade to slide off automatically. The conveyor roller 2 realizes automated feeding of the sheet, replacing manual feeding and improving the continuity of processing. The processing table 11 provides a flat working surface for cutting and forming, while the notch 15 provides a channel for blade collection, reducing manual handling.

[0017] The power system for conveyor roller 2 includes: 1. Drive motor: A servo motor (rated power 1.5kW, speed 1500rpm) is used as the main drive source and is connected to the input end of the conveyor roller 22 through a synchronous pulley set; the motor is equipped with a planetary reducer (reduction ratio 1:10) and the output torque reaches 15Nm.

[0018] 2. Control system: The motor is driven by a PLC controller (Siemens S7-200SMART) and achieves closed-loop control through encoder feedback, with a linear speed accuracy of ±0.1m / min; it has a built-in multi-speed program that can switch the conveying speed according to the material of the sheet (adjustable from 5-20m / min).

[0019] Please see Figure 1-4 : The processing mechanism is set on the base 1. The processing mechanism includes a first support plate 3 and a first lifting seat 4. The first lifting seat 4 is located inside the first lifting plate and is driven to lift by a hydraulic cylinder 16 at the top of the first support plate 3. A blade 5 and a forming strip 6 are installed at the bottom of the first lifting seat 4. After the blade 5 cuts the blade, the forming strip 6 shapes the blade.

[0020] The hydraulic cylinder 16 drives the first lifting seat 4 to rise and fall along the first support plate 3. When it descends, the blade 5 at the bottom first cooperates with the cutting groove 12 of the processing table 11 to complete the cutting. The forming strip 6 is located on one side of the blade 5. Then the forming strip 6 presses against the forming groove 14 of the inclined surface 13 of the processing table 11 to perform arc-shaped pressing and forming of the cut blade. The cutting and forming processes are integrated into the same mechanism, saving the equipment switching time of traditional step-by-step processing and improving the processing efficiency of a single blade. The blade 5 and the forming strip 6 move synchronously to ensure the matching degree of the cutting size and the forming arc.

[0021] The power system for hydraulic cylinder 16 includes: 1. Hydraulic pump station: The system uses a gear pump (displacement 10mL / r, rated pressure 16MPa) for oil supply and is driven by a three-phase asynchronous motor (power 3kW, speed 1450rpm). The oil tank has a capacity of 40L and a built-in air-cooled cooler (temperature control range 35-55℃) to ensure that the system can work continuously for 8 hours without overheating.

[0022] 2. Control loop: The hydraulic cylinder 16 is controlled by a three-position four-way solenoid directional valve (center position functional type O), and the flow rate is precisely adjusted (flow range 5-20L / min) in conjunction with the speed control valve; the system pressure is set by a pilot-operated relief valve (working pressure 8-12MPa adjustable), and the equipment is automatically unloaded to protect it in case of overload.

[0023] 3. Displacement control: Hydraulic cylinder 16 (63mm diameter, 100mm stroke) is equipped with a magnetostrictive displacement sensor (accuracy ±0.05mm) to provide real-time feedback on piston position.

[0024] Please see Figure 2 : The processing table 11 and the top of the conveyor roller 2 are flush. The top of the processing table 11 is provided with a cutting groove 12 and a corresponding blade 5. The top of the processing table 11 is provided with an inclined surface 13 on one side of the cutting groove 12, which is inclined towards the notch 15. A forming groove 14 is provided on the inclined surface 13. The forming groove 14 and the forming strip 6 are adapted to each other. A container is placed below the notch 15. After cutting and forming, the blade falls along the inclined surface 13 into the container below the notch 15 for collection.

[0025] The cutting groove 12 is precisely aligned with the blade 5 to ensure that the blade 5 does not deviate during cutting; the inclined surface 13 slopes from the cutting groove 12 to the notch 15, and the forming groove 14 is adapted to the shape of the forming strip 6, so that the blade conforms to the groove surface and forms an arc under the pressure of the forming strip 6. The inclined surface 13 and the forming groove 14 work together to complete the blade forming and guide the blade to slide down; the container below the notch 15 is used to collect the formed blade, realizing automatic collection and improving production efficiency.

[0026] For a preferred implementation, please refer to Figure 3-4 : It also includes several sets of limiting posts 7, which are set on the top of the forming strip 6, and the top of the limiting posts 7 is provided with connecting rods 8. It also includes cavities 9, which are opened in the first lifting seat 4. Several sets of cavities 9 are set inside one side of the first lifting seat 4. The connecting rods 8 are slidably inserted into the bottom of the first lifting seat 4, and the upper end of the connecting rods 8 extends into the cavity 9 and is connected to a slider. The slider and the cavity 9 are slidably engaged. A compression spring 10 is set in the cavity 9 between the slider and the top of the cavity 9. Under normal conditions, the lower end of the forming strip 6 is 1-2 cm lower than the lower end of the blade 5. During cutting, the forming strip 6 first contacts the plate, and then the blade 5 cuts. The forming strip 6 presses the cut blade against the inclined surface 13. The connecting rods 8 continue to retract into the cavity 9 until the limiting posts 7 abut against the bottom surface of the first lifting seat 4, so that the forming strip 6 presses the blade into the forming groove 14 to achieve the purpose of forming. After the formed blade is reset in the first lifting seat 4, it slides down the inclined surface 13.

[0027] Normally, the forming strip 6, being lower than the blade 5, contacts the plate first. During the pressing process, the forming strip 6 presses the cut blade against the inclined surface 13. Under pressure, the connecting rod 8 drives the slider to slide within the cavity 9 and compress the spring 10. When the limiting post 7 touches the bottom surface of the first lifting seat 4, the forming strip 6 completely presses the blade into the forming groove 14 to complete the forming. After the first lifting seat 4 resets, the blade slides down along the inclined surface 13. This ensures that the forming strip 6 contacts the plate first, realizing the sequence of cutting and forming, and guaranteeing the forming quality. Through the cooperation of the limiting post 7, connecting rod 8, slider, and compression spring 10, the pressing degree of the forming strip 6 is precisely controlled, enabling the blade to be accurately formed.

[0028] For a preferred implementation, please refer to Figure 1 and 5 : It also includes a positioning mechanism, which is mounted on the base 1 and located on one side of the processing mechanism. The positioning mechanism includes a second support plate 17 and a second lifting seat 19. The second lifting seat 19 is located inside the second support plate 17, and an electric push rod 18 for driving the second lifting seat 19 is installed on the top of the second support plate 17. A pressure plate 20 is provided at the bottom of the second lifting seat 19. Several sets of rubber positioning strips 21 are evenly distributed at the bottom of the pressure plate 20. The positioning strips 21 correspond one-to-one with the rollers of the conveyor roller 2 below. When processing the sheet material, the pressure plate 20 descends, causing the positioning strips 21 to abut against the top surface of the sheet material, pressing and positioning the sheet material on the conveyor roller 2 to prevent the sheet material from shifting.

[0029] The electric push rod 18 drives the second lifting seat 19 to descend. The rubber positioning strip 21 at the bottom of the pressure plate 20 corresponds to the conveying roller 2, pressing the plate tightly onto the conveying roller 2 to prevent the plate from shifting during cutting and forming. The rubber positioning strip 21 ensures firm positioning and avoids damaging the surface of the plate.

[0030] Please refer to Figure 3-4 A mounting groove is provided on one side of the bottom of the first lifting seat 4 for inserting the upper part of the blade 5. Screw holes are provided on the upper part of the blade 5 and the outer wall of the first lifting seat 4 respectively, and the blade 5 is installed by means of fixing screws.

[0031] Insert the upper part of the blade 5 into the mounting slot at the bottom of the first lifting seat 4, align the blade 5 with the screw hole on the first lifting seat 4, and then screw in the fixing screw to fix the blade 5 on the first lifting seat 4; this facilitates the installation and replacement of the blade 5, improves the maintenance efficiency of the equipment, and reduces maintenance costs.

[0032] Please refer to Figure 3-5 The first support plate 3 and the second support plate 17 are both arranged in a U-shape. The two arms of the first support plate 3 and the second support plate 17 are provided with sliding grooves. The first lifting seat 4 and the second lifting seat 19 are both provided with sliders. The sliders at both ends of the first lifting seat 4 are slidably engaged with the sliding grooves of the first support plate 3, and the sliders at both ends of the second lifting seat 19 are slidably engaged with the sliding grooves of the second support plate 17, thereby guiding the lifting of the first lifting seat 4 and the second lifting seat 19.

[0033] During the lifting process, the sliders at both ends of the first lifting seat 4 and the second lifting seat 19 slide in the corresponding grooves, restricting the movement direction of the lifting seats so that they can only move in a straight line along the grooves; this ensures the stability and accuracy of the lifting of the first lifting seat 4 and the second lifting seat 19, avoids deviation during the lifting process, and thus improves the accuracy of cutting, forming and positioning.

[0034] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
