Technical Field

[0001] This utility model relates to a fixed-length cutting equipment for coiled sealing strip products, belonging to the field of automotive parts technology. It can replace the manual cutting process of coiled sealing strips, resulting in higher production efficiency. At the same time, it solves the problem of unstable cutting length due to human factors and the production safety problem caused by the cutting knife. Background Technology

[0002] In the processing and production of coiled products such as sealing strips, the cutting process is a crucial step to ensure that the product meets specific length requirements. Traditionally, the cutting of coiled products mainly relies on manual operation of the cutting machine. The operator must manually insert the sealing strip through the cutting blade, then manually move the end of the sealing strip to the rear limit stop, confirm the cutting length by visual inspection and experience, and then step on the foot switch to use the cutting machine to complete the cutting of the sealing strip. This process is repeated to complete the production.

[0003] However, this manual cutting method has many drawbacks. On the one hand, the intervention of manual operation limits production efficiency, making it difficult to achieve efficient and continuous large-scale production, and failing to meet the demands of modern industrial automation for high-efficiency output. On the other hand, human factors lead to poor stability of cutting dimensions, making it difficult to accurately control the error range, easily resulting in length deviations and affecting product quality consistency. Furthermore, operators manually adjust the position of the sealing strip during the cutting process, with their hands frequently approaching the cutting blade area, posing a high safety hazard and easily causing accidental injuries, which is detrimental to the construction of a safe production environment. Therefore, there is an urgent need for an automatic sealing strip cutting device that can improve production efficiency, stabilize cutting dimensions, and eliminate the safety hazards of manual cutting. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic sealing strip cutting device to solve the problems of low production efficiency, poor dimensional stability and safety hazards caused by manual cutting of sealing strips in the prior art.

[0005] To achieve the above objectives, the present invention provides a fixed-length cutting device for coiled sealing strips, comprising a base, a lead screw slide on the base, a movable gripper on the lead screw slide, a servo motor at one end of the lead screw slide to drive the movable gripper to move laterally via the lead screw of the lead screw slide, a cutting blade at the other end of the base on the lead screw slide, a fixed gripper on the side of the base near the movable gripper on the side of the cutting blade on the side of the base away from the movable gripper on the side of the base on the cutting blade away from the movable gripper on the side of the base on the side of the base on the side of the base away from the cutting blade on the side of the movable gripper on the side of the base on the side of the base on the side of the base away from the moving gripper on the side of the cutting blade on the side of the base on the side of the base on the side of the base on the side away from the movable gripper on the side of the base on the side of the cutter on the side on the side of the base on the side on the side of the cutter away from the movable gripper on the side of the base on the side on the side of the cutter on the side ...

[0006] Preferably, the lead screw is mounted on the base via a bearing seat, and the nut seat on the lead screw is connected to the movable gripper to ensure smooth movement of the movable gripper, provide a platform for left and right movement of the movable gripper, and realize the lateral positioning of the gripper on the equipment.

[0007] Preferably, the servo motor is connected to the lead screw.

[0008] Preferably, the servo motor transmits power to the lead screw via a coupling, driving the moving gripper to achieve precise positioning.

[0009] Preferably, the movable gripper includes a gripper mechanism, a pneumatic component, and a connecting component. The gripper mechanism is driven to open and close by the pneumatic component to grip the sealing strip. It can move left and right along the lead screw slide to realize the transfer and positioning of the sealing strip. After the cutting is completed, the finished product is removed from the cutting blade position and cooperates with other components to complete the automated process of continuous fixed-length cutting.

[0010] Preferably, the cutting blade includes a cutting tool, a cutting tool holder, and a driving device. The driving device is vertically mounted on the base and can drive the cutting tool holder downward. The cutting tool is fixed at the bottom of the cutting tool holder. When the sealing strip is fed into place, the cutting tool moves downward under the action of the driving device to complete the cutting operation of the sealing strip.

[0011] Preferably, the fixed gripper includes a gripper body, a pneumatic component, and a connecting component. The gripper body is located on the left side of the cutting blade. The pneumatic component drives the gripper body to open and close, which can clamp the sealing strip during cutting, prevent the sealing strip from shaking during the cutting process, and ensure the quality of the cut end face.

[0012] Preferably, the pressing cylinder is located above the feeding slide near the end of the cutting blade.

[0013] Preferably, the pressing cylinder includes a cylinder and a pressure plate. The cylinder is fixed above the base, and the piston rod of the cylinder is arranged downward and connected to the pressure plate, which can press down the sealing strip to prevent the sealing strip from changing position.

[0014] In summary, this utility model has the following beneficial technical effects:

[0015] This invention significantly improves production efficiency, enabling continuous and efficient fixed-length cutting operations.

Furthermore, the coordinated operation of all components of the equipment achieves a fully automated process from fixing, transferring, and cutting the sealing strip to the discharge of the finished product. This not only reduces labor costs but also optimizes the overall production layout, demonstrating promising application prospects and practical value. Attached Figure Description

[0022] 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.

[0023] This utility model relates to a fixed-length cutting device for coiled sealing strips, aiming to improve production efficiency, stabilize cutting dimensions, and eliminate the safety hazards of manual cutting. This utility model can precisely control the cutting length using a servo motor, with an error rate controlled within ±0.5mm. It mainly consists of a feeding slide 1, a pressing cylinder 2, a fixed gripper 3, a cutting blade 4, a lead screw slide 5, a moving gripper 6, a servo motor 7, and other mechanical components.

[0024] The equipment features a frame structure welded from metal profiles, providing high rigidity and stability to ensure its stability during the cutting process. A crossbeam and base are located in the middle of the frame to mount and secure the servo motor 7, lead screw slide 5, and other related components, supporting and ensuring their smooth operation.

[0025] The feeding slide 1 is located at the right end of the base. Because in traditional equipment, after cutting, the end face of the sealing strip is on the right side of the cutting blade 4, and the moving gripper 6 cannot pass through the cutting blade 4 to pick up the sealing strip, the main function of the feeding slide 1 in this utility model is to feed the end face of the sealing strip from the right side of the cutting blade 4 to the left side, so that the moving gripper 6 can pick up the sealing strip and ensure that the material after cutting can smoothly enter the next process.

[0026] The pressing cylinder 2 is located above the left end of the feeding slide 1, and includes a cylinder and a pressure plate. The cylinder is fixed to the base by a bracket, and its piston rod is connected to the pressure plate. During equipment operation, the pressing cylinder 2 presses down to clamp the sealing strip, preventing the sealing strip from shifting position when the feeding slide 1 feeds material to the left, thus ensuring the accuracy of the cutting dimensions.

[0027] The fixed gripper 3 is located on the left side of the cutting blade 4 and consists of a gripper body, pneumatic components, and connecting parts. The gripper body is mounted on the base and located on the left side of the cutting blade 4. The pneumatic components drive the gripper to open and close. During cutting, the fixed gripper 3 clamps the sealing strip to prevent the sealing strip from shaking during the cutting process, ensuring the quality of the cut end face and preventing poor end face quality caused by shaking, which would affect product quality.

[0028] The cutting blade 4 is mounted above the base and is a vertically movable structure. It consists of a blade, a blade holder, and a drive unit. The drive unit can be a pneumatic cylinder or a hydraulic cylinder, which is vertically mounted on the base and can drive the blade holder downwards. The blade is fixed at the bottom of the blade holder. When the sealing strip is fed into position, the blade moves downwards under the action of the drive unit to complete the cutting operation of the sealing strip. It is a key component for achieving fixed-length cutting of the sealing strip.

[0029] The lead screw slide 5 is horizontally mounted on the base and mainly consists of a lead screw and a nut seat. The lead screw is mounted on the base via a bearing seat, and the nut seat on the lead screw is connected to the movable gripper 6, ensuring the smooth movement of the movable gripper 6. The lead screw slide 5 provides a platform for the movable gripper 6 to move left and right, realizing the lateral positioning of the gripper on the equipment and ensuring that the movable gripper 6 can accurately reach the preset position for gripping and transferring operations.

[0030] The movable gripper 6 is mounted on the nut seat of the lead screw slide 5 and consists of a gripper mechanism, pneumatic components, and connecting parts. The gripper mechanism is driven to open and close by pneumatic components to grip the sealing strip. It can move left and right along the lead screw slide 5 to realize the transfer and positioning of the sealing strip. After cutting, the finished product is removed from the cutting blade 4 position and works with other components to complete the automated process of continuous fixed-length cutting.

[0031] The servo motor 7 is installed at the left end of the lead screw slide 5 and connected to the lead screw of the lead screw slide 5. Power is transmitted to the lead screw through a coupling. As one of the power sources of the equipment, the servo motor 7 drives the lead screw slide 5, which in turn drives the moving gripper 6 to achieve precise positioning. This ensures that the moving gripper 6 can move according to the preset program and position requirements, guaranteeing the accuracy and stability of the cutting dimensions, with the error rate controlled within ±0.5mm.

[0032] The synergistic effect and workflow of the various components of this utility model are as follows:

[0033] 1. In the initial state of the equipment, the feeding slide 1 is stopped on the right, the pressing cylinder 2 is in the upper position, the fixed gripper 3 is open, the cutting blade 4 is in the upper position, and the moving gripper 6 is stopped at the leftmost origin position.

[0034] 2. After starting the equipment, the pressing cylinder 2 first presses down to clamp the sealing strip;

[0035] 3. Then the feeding slide 1 moves to the left, sending the end face of the sealing strip out of the left side of the cutting knife 4, so that the sealing strip enters the gripping range of the moving gripper 6.

[0036] 4. After a short delay (preferably 0.5s), the moving jaw 6 closes and holds the sealing strip;

[0037] 5. The pressing cylinder returns to its upper position twice;

[0038] 6. Move the gripper 6 to the left to the preset travel position;

[0039] 7. The sealing strip is fixed by the downward movement of the pressure cylinder 2.

[0040] 8. The cutting blade makes four downward cuts to complete the cutting operation to the set size;

[0041] 9. After cutting, move the gripper 6 to the left for a certain distance (e.g., 200mm) to remove the finished product from the cutting blade 4 position;

[0042] 10. After the finished product exits the cutting blade position 4, the moving gripper 6 opens, and the finished product is discharged from the equipment;

[0043] 11. Move gripper 6 to the right and return to the original position to prepare for the next round of cutting;

[0044] 12. By repeating this process, continuous and efficient fixed-length cutting production can be achieved.

[0045] This utility model of automatic sealing strip cutting equipment effectively improves production efficiency, stabilizes cutting dimensions, and eliminates the safety hazards of manual cutting through the reasonable structure and precise coordination of its components. It is suitable for the automated cutting and processing of coiled sealing strips and has good application prospects and practical value.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
