Description

Technical Field

[0001] This utility model relates to a cutting device, specifically a cutting device for a door strip. Background Technology

[0002] A door strip (also known as an internal cut-out sealing strip or internal water-cutting sealing strip) is produced through extrusion. It consists of spaced-apart aggregate (made of metal) and a rubber strip wrapped around the aggregate. The aggregate increases the plasticity and toughness of the door strip, improving its quality. After extrusion, the door strip needs to be cut for storage and transportation.

[0003] Patent application CN206644025U discloses a cutting device for an automotive sealing strip production line. The device includes a frame with a cutting assembly. A movable plate is slidably connected to the frame along the product conveying direction. The cutting assembly is connected to the movable plate, and a pressure plate is slidably connected to the movable plate in a vertical direction. The frame has a slide rail parallel to the product conveying direction, and the movable plate is embedded in and slidably connected to the slide rail. This invention provides a cutting device for an automotive sealing strip production line that can move along with the product in the product output direction, maintaining the relative stillness of the cutting assembly and the product, thereby improving the product cutting quality.

[0004] The aforementioned cutting device can cut a single-layer door strip, but when cutting a single-layer door strip containing aggregate, it cannot accurately cut on the rubber strip between the aggregate, posing a risk of cutting the aggregate. Therefore, it is necessary to redesign a single-layer door strip cutting device to solve the above problem. Summary of the Invention

[0005] The purpose of this utility model is to provide a simple slitting device for a single-strip material that can effectively ensure accurate cutting position and is not easy to cut aggregate.

[0006] The technical solution of this utility model is:

[0007] A single-layer gate strip cutting device comprises a frame, a conveying mechanism, a clamping and fixing mechanism, a detection probe, and a cutting mechanism. The device is characterized by: a conveying mechanism mounted on the frame; a clamping and fixing mechanism mounted on the frame at the rear end of the conveying mechanism; a detection probe for detecting aggregate positioned between the clamping and fixing mechanism and the conveying mechanism; and a cutting mechanism mounted on the frame above the clamping and fixing mechanism.

[0008] The conveying mechanism consists of a lower conveyor belt, a conveyor belt lifting cylinder, a conveyor belt lifting slide, and an upper conveyor belt. The conveyor belt lifting cylinder is installed above the lower conveyor belt, and the piston rod of the conveyor belt lifting cylinder is connected to the conveyor belt lifting slide. The upper conveyor belt is installed on the conveyor belt lifting slide. The lower conveyor belt and the conveyor belt lifting cylinder are respectively connected to the frame, and the conveyor belt lifting slide is slidably connected to the frame through a slide rail.

[0009] The clamping and fixing mechanism consists of a lower clamping plate, a clamping cylinder, and an upper clamping plate. The clamping cylinder is arranged side by side on the outer side of the lower clamping plate, and the upper clamping plate is connected to the piston rod of the clamping cylinder. The upper clamping plate extends above the lower clamping plate. The lower clamping plate and the clamping cylinder are respectively connected to the frame.

[0010] The upper clamping plate is L-shaped, and a vacuum head is provided between the upper clamping plates. The inner side of the vacuum head is provided with a vacuum groove, and a vacuum tube is connected to the outer side of the vacuum head. One end of the vacuum tube is connected to the vacuum groove, and the other end of the vacuum tube is connected to the vacuum cleaner.

[0011] The cutting mechanism consists of a cutting lifting cylinder, a cutting slide, a cutting motor, and a circular saw. The cutting slide is movably mounted on the frame below the cutting lifting cylinder via a slide rail, and the cutting slide is connected to the piston rod of the cutting lifting cylinder. The cutting motor is fixedly mounted on the cutting slide, and the circular saw is mounted on the output shaft of the cutting motor. The cutting lifting cylinder is connected to the frame.

[0012] The beneficial effects of this utility model are as follows:

[0013] This single-strip cutting device uses a detection probe to detect the aggregate within the single-strip, accurately determining its position (including the start and end points). This, combined with the conveying and clamping mechanisms, precisely positions the single-strip, ensuring the aggregate is positioned below the cutting mechanism. This allows for accurate cutting between the aggregate, minimizing damage and significantly reducing the risk of cutting-related harm. It solves the problem of existing cutting devices failing to accurately cut single-strips containing aggregate, often resulting in aggregate damage. It is particularly suitable for cutting single-strips containing aggregate. Attached Figure Description

Detailed Implementation

[0017] This single-strip cutting device consists of a frame 1, a conveying mechanism, a clamping and fixing mechanism, a detection probe 2, and a cutting mechanism. The conveying mechanism is mounted on the frame 1 to transport the single-strip strip backwards. A clamping and fixing mechanism is mounted on the frame 1 at the rear of the conveying mechanism to clamp and fix the single-strip strip, maintaining its position during cutting and preventing displacement, thus ensuring a clean cut. A detection probe 2 for detecting aggregate is located between the clamping and fixing mechanism and the conveying mechanism. The detection probe 2 detects the aggregate, controlling the conveying of the single-strip strip and consequently controlling its cutting position, preventing damage to the aggregate during cutting and ensuring the quality of the single-strip strip. Preferably, the detection probe 2 is a HAD-12er55b2.5-5NK1 type KLASCHKA sensor. The cutting mechanism is mounted on the frame 1 above the clamping and fixing mechanism to cut the single-strip strip.

[0018] The conveying mechanism consists of a lower conveyor belt 3, a conveyor belt lifting cylinder 4, a conveyor belt lifting slide 5, and an upper conveyor belt 6. The lower conveyor belt lifting cylinder 4 is installed above the lower conveyor belt 3. The piston rod of the conveyor belt lifting cylinder 4 is connected to the conveyor belt lifting slide 5, and the upper conveyor belt 6 is installed on the conveyor belt lifting slide 5. The lower conveyor belt 3 and the conveyor belt lifting cylinder 4 are respectively connected to the frame 1, and the conveyor belt lifting slide 5 is slidably connected to the frame 1 through a slide rail. The function of the conveyor belt lifting cylinder 4 is to drive the conveyor belt lifting slide 5 to rise and fall, thereby driving the upper conveyor belt 6 to rise and fall, so that the upper conveyor belt 6 can move relative to the lower conveyor belt. During the downward movement of the upper conveyor belt 6, the upper conveyor belt 6 and the lower conveyor belt 3 approach each other, thereby clamping a gate strip between the upper conveyor belt 6 and the lower conveyor belt 3 and conveying it forward. During the conveying process, the clamping of the gate strip by the upper conveyor belt 6 and the lower conveyor belt 3 can also straighten the gate strip. During the upward movement of the upper conveyor belt 6, the upper conveyor belt 6 and the lower conveyor belt 3 are kept at a certain distance, thereby guiding the gate strip to pass through the space between the upper conveyor belt 6 and the lower conveyor belt 3, which facilitates the loading of materials.

[0019] The clamping and fixing mechanism consists of a lower clamping plate 7, a clamping cylinder 8, and an upper clamping plate 9. The clamping cylinder 8 is arranged parallel to the outer side of the lower clamping plate 7, and the upper clamping plate 9 is connected to the piston rod of the clamping cylinder 8. The upper clamping plate 9 extends above the lower clamping plate 7. The lower clamping plate 7 and the clamping cylinder 8 are respectively connected to the frame 1. The function of the clamping cylinder 8 is to drive the upper clamping plate 9 to rise and fall, thereby coordinating the rising and falling of the upper clamping plate 9 with the lower clamping plate 7 to clamp and fix a door strip, ensuring that the door strip does not easily shift during the cutting process. This ensures a neat cut on the door strip and improves the quality of the cut door strip.

[0020] The upper clamping plate 9 is L-shaped, and a suction head 10 is arranged between the upper clamping plates 9. The inner side of the suction head 10 is provided with a suction groove 11, and a vacuum tube 12 is connected to the outer side of the suction head 10. One end of the vacuum tube 12 is connected to the suction groove 11, and the other end of the vacuum tube 12 is connected to a vacuum cleaner. The function of the vacuum tube 12 is to work with the suction groove 11 on the suction head 10 to absorb the debris generated during the cutting process, thereby keeping the environment clean.

[0021] The cutting mechanism consists of a cutting lifting cylinder 13, a cutting slide 14, a cutting motor 15, and a circular saw 16. The cutting slide 14 is movably mounted on the frame 1 below the cutting lifting cylinder 13 via a slide rail, and the cutting slide 14 is connected to the piston rod of the cutting lifting cylinder 13. The cutting motor 15 is fixedly mounted on the cutting slide 14, and the circular saw 16 is mounted on the output shaft of the cutting motor 15. The cutting lifting cylinder 13 is connected to the frame 1. The function of the cutting lifting cylinder 13 is to drive the cutting slide 14 to rise and fall, which in turn drives the cutting motor 15 to rise and fall, thereby driving the circular saw 16 to rise and fall. During the rising and falling of the circular saw 16, the rotating circular saw cuts a door strip.

[0022] When the cutting device for the single-strip section is working, the end of the single-strip section is sequentially passed between the upper conveyor belt 6 and the lower conveyor belt 3, inside the detection probe 2, and between the upper clamping plate 9 and the lower clamping plate 7. After the single-strip section is in place, the conveyor belt lifting cylinder 4 of the conveying mechanism is activated. The conveyor belt lifting cylinder 4 drives the upper conveyor belt 6 downward through the conveyor belt lifting slide 5, clamping the single-strip section between the upper conveyor belt 6 and the lower conveyor belt 3. After the upper conveyor belt 6 reaches its lower position, both the upper conveyor belt 6 and the lower conveyor belt 3 are activated. The rotation of the upper conveyor belt 6 and the lower conveyor belt 3 pushes the single-strip section backward. During the movement of the single-strip section, the detection probe 2 detects the aggregate in the single-strip section. By detecting the aggregate, the rotation of the upper conveyor belt 6 and the lower conveyor belt 3 is controlled, thereby controlling the position of the single-strip section. When the position of the aggregate in the single-strip section is below the circular saw 16 of the cutting mechanism, the upper conveyor belt 6 and the lower conveyor belt 3 stop, thereby stopping the backward conveying of the single-strip section. After one door strip stops, the clamping cylinder 8 of the clamping and fixing mechanism is activated, driving the upper clamping plate 9 downwards. The upper clamping plate 9, in conjunction with the lower clamping plate 7, clamps and fixes the door strip. After the door strip is clamped and fixed, the cutting lifting cylinder 13 of the cutting mechanism is activated. The cutting lifting cylinder 13 drives the circular saw 16 downwards via the cutting lifting slide 14 and the cutting motor 15. During the downward movement of the circular saw 16, the cutting motor 15 is activated, causing the circular saw 16 to rotate. During the downward movement of the circular saw 16, the vacuum cleaner connected to the vacuum tube 12 is activated, creating negative pressure in the suction groove 11 of the suction head 10 through the vacuum tube 12. During the downward movement of the circular saw 16, the rotating circular saw 16 gradually cuts the door strip, and the dust generated during cutting is removed by the suction head 10. After cutting is completed, the cutting motor 15 is stopped, the cutting lifting cylinder 13 drives the circular saw 16 upwards to reset, and the clamping cylinder 8 drives the upper clamping plate 9 upwards to reset. After the upper clamping plate 9 moves to its position, the upper conveyor belt 6 and the lower conveyor belt 3 are started to continue conveying a door strip, entering the next work cycle.

[0023] When the cutting device for a single strip is in operation, the frame 1 moves with the single strip via a cylinder or lead screw pair, and the single strip is continuously conveyed forward and then continuously cut; when the frame 1 is fixed in position, the conveying of the single strip is stopped during the cutting process.

[0024] This single-strip cutting device uses a detection probe 2 to detect the aggregate within the single-strip, accurately determining its position. This, combined with the conveying and clamping mechanisms, ensures the single-strip is precisely positioned below the cutting mechanism, allowing for accurate cutting between the aggregate pieces and minimizing damage. This effectively reduces the risk of aggregate breakage during cutting. It solves the problem of existing cutting devices failing to accurately cut single-strips containing aggregate, often resulting in aggregate damage. It is particularly suitable for cutting single-strips containing aggregate.
