Description

Technical Field

[0001] This utility model relates to PVC louver processing equipment, and more specifically to a blade cutting and positioning device for PVC louver production and processing. Background Technology

[0002] Existing PVC louver blades require precise cutting during production to accommodate different sizes. Traditional cutting methods, especially in the positioning and clamping stages, often rely on manual operation or simple mechanical clamps.

[0003] Existing technologies of this type have the following problems in practical applications. On the one hand, the centering and positioning accuracy of the blades before cutting depends on the operator's experience, which is prone to errors, affecting the quality of the final product and production efficiency. On the other hand, simple clamping structures cannot guarantee the stability and rigidity of blade clamping during high-speed cutting, and the blades are prone to displacement or wobbling, further reducing cutting accuracy. In addition, PVC materials generate a large amount of fine dust during high-speed cutting, and many cutting devices lack effective dust removal and filtration systems, resulting in dust dispersion, seriously polluting the working environment and posing a potential threat to the health of operators. Especially in terms of automated and precise positioning and stable clamping of blades, the structures in existing technologies are often quite complex and lack sufficient positioning reliability.

[0004] Therefore, this utility model proposes a blade cutting and positioning device for PVC louver production and processing to solve the defects of low blade cutting and positioning accuracy, insufficient clamping stability and safety in the prior art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a blade cutting and positioning device for PVC louver production and processing, which aims to improve the problems of low blade cutting and positioning accuracy, insufficient clamping stability, and environmental pollution caused by the lack of efficient dust removal structure in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a blade cutting and positioning device for PVC louver production and processing, comprising: a workbench, an electric saw, a suction hood, a ventilation pipe, a connecting mechanism, a filtering mechanism, a ventilator, and a clamping and pushing mechanism;

[0007] The electric saw is fixedly mounted on the workbench, the suction hood is positioned above the cutting area of ​​the workbench, and the ventilator is fixedly mounted at the lower end of the workbench. The ventilator is connected to the suction hood via the ventilation pipe, the connecting mechanism, and the filter mechanism, forming a complete dust removal system.

[0008] The clamping and pushing mechanism is mounted on the worktable and is used to clamp and push the blade for positioning.

[0009] The clamping and pushing mechanism includes: an L-shaped bracket, a first slide rod, a housing, an electric telescopic rod, a third slide rod, a sliding plate, and a clamping plate. Two L-shaped brackets are provided and fixed to the upper end of the worktable. The first slide rod is fixed to the opposite side of the L-shaped bracket. The housing is sleeved through the first slide rod and can slide along the first slide rod.

[0010] The electric telescopic rod is fixedly connected to the L-shaped bracket, and the telescopic end of the electric telescopic rod passes through the outer shell and is fixedly connected to the third sliding rod;

[0011] The inner wall of the outer shell has two second sliding grooves on the upper and lower sides, and a second sliding rod is fixed in each groove. The two sets of second sliding rods are arranged in a figure-eight shape, with their openings facing the electric telescopic rod.

[0012] The third slide rod passes through the slide piece, and the two sides of the slide piece are sleeved through the second slide rod. The clamping plate is fixedly connected to the slide piece. The movement of the third slide rod forces the slide pieces to move closer together and clamp through the figure-eight arrangement of the second slide rod. This unique figure-eight guide mechanism achieves automatic centering and stable fastening of the blade clamping.

[0013] Preferably, the clamping and pushing mechanism further includes springs, two of which are fixedly connected at both ends to the outer shell and the L-shaped bracket, respectively, to provide a return pull during the blade pushing process and maintain a constant clamping force;

[0014] Preferably, the filtration mechanism includes: a filter frame, a handle, a double-ended bolt, a clamping plate, and a sponge filter screen, with the handle fixedly disposed at the lower end of the filter frame;

[0015] Preferably, the connecting mechanism includes a connecting pipe, and a slot is provided at the center of the lower end of the connecting pipe. The filtering mechanism is snapped into the slot through the filtering frame, so as to realize the quick and detachable connection of the filtering mechanism and facilitate maintenance.

[0016] Preferably, the filter frame is provided with two first sliding grooves, and the sponge filter is movably disposed in the first sliding grooves for easy replacement or cleaning;

[0017] Preferably, the double-ended bolt is rotatably disposed in a circular hole opened on the filter frame, and the clamping plate is threadedly sleeved on both sides of the double-ended bolt. The two ends of the double-ended bolt have opposite thread directions to ensure that the clamping plate moves synchronously in opposite directions when rotating, which is used to clamp or loosen the sponge filter screen.

[0018] Preferably, the contact surface between the third slide rod and the slide plate, the contact surface between the outer shell and the first slide rod, and the contact surface between the slide plate and the second slide rod are all set as smooth contact surfaces to reduce frictional resistance and ensure smooth movement of the mechanism;

[0019] Preferably, after the electric telescopic rod pushes the sliding plate to move and clamp the blade through the third sliding rod, the sliding plate and the clamping plate together push the outer shell to slide along the first sliding rod, thereby realizing the overall pushing and precise positioning of the blade.

[0020] This utility model has the following beneficial effects:

[0021] 1. This utility model, by setting up a clamping and pushing mechanism, uses an electric telescopic rod to drive the third slide rod, and then uses the second slide rod arranged in a figure-eight shape to force the slide plate and the clamping plate to move closer to each other, thereby realizing the automatic centering and clamping of the blade and precise pushing and positioning. It solves the problems of low blade cutting positioning accuracy and unstable clamping in the prior art, and achieves the technical effect of improving cutting positioning accuracy and work efficiency.

[0022] 2. This utility model, by setting a spring in the clamping and pushing mechanism, the spring is stretched when pushed, and its rebound force can compensate for the gap or looseness during the movement, ensuring that the clamping force of the clamping plate on the blade remains constant, thus achieving the technical effect of ensuring the stability and reliability of cutting positioning.

[0023] 3. This utility model, through the design of a filtration mechanism, wherein the double-headed bolt uses a reverse thread structure to drive the clamping plate to move synchronously in the opposite direction to clamp or loosen the sponge filter screen, and cooperates with the slot to realize the quick disassembly of the filtration mechanism, solves the problems of complex replacement and difficult maintenance of filter consumables in the prior art, and achieves the technical effect of improving the maintainability of the equipment and reducing maintenance time.

Detailed Implementation

[0033] 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.

[0034] Reference Figures 1-7 This utility model provides an embodiment of a blade cutting and positioning device for PVC louver production and processing, including a workbench 1, an electric saw 2, a suction hood 3, a ventilation pipe 4, a connecting mechanism 5, a filtering mechanism 6, a ventilator 7, and a clamping and pushing mechanism 8. The workbench 1 serves as the installation base platform for the entire device. The electric saw 2 is fixedly installed at one end of the workbench 1 for performing blade cutting operations. The clamping and pushing mechanism 8 is installed at the upper end of the workbench 1, relative to the electric saw 2, for clamping the blade and accurately pushing it below the electric saw 2 for positioning and cutting. The ventilator 7 is fixedly installed at the lower end of the workbench 1 for providing the suction power required for dust removal. The suction hood 3 is installed above the cutting area of ​​the workbench 1 for collecting impurities and dust generated during cutting to the greatest extent.

[0035] The suction hood 3 is connected to the fan 7 via the ventilation pipe 4, the connecting mechanism 5, and the filter mechanism 6 in sequence, forming a complete dust removal system. The filter mechanism 6 is detachably installed in the airflow path to filter dust and protect the health of the operators.

[0036] The main structure of the clamping and pushing mechanism 8 includes: an L-shaped bracket 801, a first slide bar 802, a housing 804, an electric telescopic rod 803, a third slide bar 808, a slide plate 809, and a clamping plate 810. Two L-shaped brackets 801 are provided and are fixedly connected to the upper end of the workbench 1 to serve as the base of the clamping mechanism for fixing the motion guide components.

[0037] The first slide rod 802 is fixedly connected to the opposite side of the L-shaped bracket 801 and is used to provide sliding guidance for the entire housing 804 and its internal mechanism. The housing 804 is sleeved through the outer end of the first slide rod 802 and can slide along the length of the first slide rod 802. Its function is to serve as the overall motion carrier when the blade is pushed. The electric telescopic rod 803 is fixedly connected to the L-shaped bracket 801. Its telescopic end passes through the housing 804 and is fixedly connected to the third slide rod 808. The thrust generated by the electric telescopic rod 803 is used to drive the third slide rod 808 to move. The two sides of the third slide rod 808 pass through the sliding pieces 809 and are used to drive the sliding pieces 809 to move synchronously.

[0038] The inner wall of the outer casing 804 has two second sliding grooves 806 on the upper and lower sides, and a second sliding rod 807 is fixedly connected in each groove. The two sets of second sliding rods 807 are arranged in a V-shape, with the opening facing the direction of the electric telescopic rod 803. The two sides of the sliding plate 809 are sleeved through the second sliding rods 807. The clamping plate 810 is fixedly connected to the sliding plate 809. When the third sliding rod 808 moves, the sliding plate 809 slides along the V-shaped second sliding rods 807 and is forced to move closer to each other, thereby realizing the clamping action of the blade.

[0039] In a preferred embodiment, the clamping and pushing mechanism 8 also includes a spring 805. Two springs 805 are provided, and the two ends of the springs 805 are respectively fixedly connected between the outer shell 804 and the L-shaped bracket 801. When the outer shell 804 moves forward to push the blade, the tension of the spring 805 can provide a return force to the clamping plate 810, ensuring that the clamping force of the clamping plate 810 on the blade is not weakened.

[0040] As another preferred embodiment, the filter mechanism 6 for filtering the dust generated during cutting includes: a filter frame 601, a handle 602, a double-ended bolt 605, a clamping plate 606, and a sponge filter screen 607. The handle 602 is fixedly installed at the lower end of the filter frame 601 for the operator to pull.

[0041] The connecting mechanism 5 includes a connecting pipe 501, and a slot 502 is provided at the center of the lower end of the connecting pipe 501. The filter mechanism 6 is snapped into the slot 502 through the filter frame 601, so as to realize the detachable connection between the filter mechanism 6 and the ventilation system.

[0042] As a further preferred embodiment, the filter frame 601 is provided with two first grooves 603, and the sponge filter 607 is movably disposed in the first grooves 603 for easy removal, replacement or cleaning.

[0043] As a further preferred embodiment, the double-ended bolt 605 is rotatably disposed in the circular hole 604 opened on the filter frame 601, and the clamping plate 606 is threadedly sleeved on both sides of the double-ended bolt 605. The two ends of the double-ended bolt 605 have opposite thread directions, ensuring that when the double-ended bolt 605 is rotated, the clamping plates 606 on both sides move synchronously in opposite directions, which is used to clamp or loosen the sponge filter screen 607.

[0044] In a preferred embodiment, the contact surfaces of the third slide bar 808 and the slide plate 809, the contact surfaces of the housing 804 and the first slide bar 802, and the contact surfaces of the slide plate 809 and the second slide bar 807 are all set as smooth contact surfaces to reduce frictional resistance and ensure the smoothness of the mechanism's movement and the accuracy of its positioning.

[0045] As another preferred embodiment, two first slide rods 802 are provided, and the outer shell 804 is sleeved through the outer ends of the two first slide rods 802 to provide stable dual-point guidance and prevent the outer shell 804 from deflecting during the pushing process;

[0046] In another preferred embodiment, after the electric telescopic rod 803 pushes the sliding plate 809 to move and clamp the blade through the third sliding rod 808, the sliding plate 809 and the clamping plate 810 jointly push the outer shell 804 to slide along the first sliding rod 802 under the continuous extension of the electric telescopic rod 803, thereby realizing the overall pushing and positioning of the blade.

[0047] Working principle: After the blade is arranged, it is placed between the two clamping plates 810 of the clamping and pushing mechanism 8. The clamping and pushing mechanism 8 is started to clamp the blade and then stopped. After confirming that the clamping is secure, the mechanism is started again to push the blade to the lower end of the electric saw 2. Then the ventilation fan 7 under the workbench 1 is turned on, and the airflow is drawn into the ventilation pipe 4 through the suction hood 3, and then enters the filter mechanism 6 for filtration through the connecting mechanism 5. The electric saw 2 is started to perform cutting. Impurities generated during the operation are continuously sucked away by the ventilation fan 7 to prevent workers from inhaling them. After the cutting is completed, the clamping and pushing mechanism 8 is started to retract the blade and release it. After long-term use of the equipment, the sponge filter 607 can be replaced through the filter mechanism 6.

[0048] Replacement procedure for sponge filter 607: Pull the fixed handle 602 at the lower end of the filter frame 601 to remove the filter mechanism 6, which is locked in the slot 502 at the center of the lower end of the connecting pipe 501; use an Allen wrench to turn the rotating double-ended bolts 605 in the two round holes 604. Because the double-ended bolts 605 are threaded onto both sides of the clamping plate 606, and the threads at both ends are in opposite directions, the front and rear sponge filters 607 will move synchronously in opposite directions when rotated, achieving clamping and loosening. When the distance between the two sponge filters 607 increases, the sponge filter 607 that is movable in the first sliding groove 603 can be removed for replacement or cleaning; after replacement, turn the double-ended bolts 605 in the opposite direction to clamp the sponge filter 607, and then re-lock the filter mechanism 6 into the slot 502.

[0049] Leaf clamping and pushing process: The electric telescopic rod 803 is activated, its telescopic end passing through the outer shell 804 and fixedly connected to the third slide rod 808, allowing the third slide rod 808 to move. Slide plates 809 pass through both sides of the third slide rod 808, with smooth contact surfaces, enabling the slide plates 809 to move synchronously. Two L-shaped brackets 801 are fixed to the upper end of the worktable 1, with two first slide rods 802 mounted on their opposite sides. The outer shell 804 is sleeved around the outer ends of the first slide rods 802, with smooth contact surfaces. Two second sliding grooves 806 are opened on the upper and lower sides of the inner wall of the outer shell 804, each containing a second slide rod 807. The two sets of second slide rods 807 are arranged in a V-shape, with their openings facing the electric telescopic rod 803. Both sides of the second slide rods 807 pass through slide plates 809, with smooth contact surfaces, allowing the slide plates 809 to move closer together along the third slide rod 808. Two springs 805 are fixed between the outer casing 804 and the L-shaped bracket 801 to which the electric telescopic rod 803 is fixed. When the clamping plate 810 is not in contact with the blade, the position of the outer casing 804 is fixed. After clamping the blade, the electric telescopic rod 803 can be paused. After confirming that the blade is aligned, it can be restarted. At this time, the clamping plate 810 contacts the blade, the slider 809 stops closing, and the electric telescopic rod 803 continues to push, causing the outer casing 804 to move forward, driving the blade to move and stretching the springs 805. If the blade exceeds the specified position, the electric telescopic rod 803 can be pulled back. The tension of the springs 805 can ensure that the clamping force of the clamping plate 810 on the blade does not weaken. After stopping, the electric saw 2 is started for cutting. After cutting is completed, the electric telescopic rod 803 is retracted, the blade is brought back to its original position, and the clamping process ends.
