[0002] Nylon sealing strips have excellent sealing performance, wear resistance, and corrosion resistance, and are widely used in doors and windows, automobiles, machinery and equipment and other fields. In the production and processing of nylon sealing strips, their ends usually need to be treated. Common treatment methods include cutting and grinding processes to ensure the flatness and dimensional accuracy of the ends of the nylon sealing strips, so that they can be better installed and matched with other components.

[0003] Currently, the processing of the ends of nylon sealing strips is mostly done manually. The ends are first cut with a cutting tool and then polished with a grinding tool. This manual processing method is not only inefficient, but also makes it difficult to guarantee the quality of processing. Problems such as uneven cutting and inadequate polishing are likely to occur, affecting the subsequent use of the nylon sealing strip.

[0004] Therefore, it is necessary to provide a new nylon sealing strip end treatment device to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please refer to the following: Figures 1-6The nylon sealing strip end processing equipment includes: a processing table 3, on the top of which a support frame 8 is fixedly installed; a top beam 9 is fixedly installed on the top of the support frame 8; a pressing mechanism is provided at the bottom of the top beam 9 to press the sealing strip from top to bottom, ensuring the stability of the cutting process; a cutting mechanism is provided on one side of the top beam 9 for cutting the end of the sealing strip; in addition, a grinding mechanism is provided on one side of the processing table 3 to grind the cut end; two straightening clamps 7 are provided on the top of the processing table 3. The straightening clamps 7 are relatively short, only slightly protruding from the top of the processing table 3. When clamping the sealing strip, their tops must be lower than the top end face of the sealing strip, so as not to interfere with the movement of the pressing plate 12 mentioned below; a concave connecting cover 4 is fixedly installed at the bottom of the processing table 3, and a double-headed screw 5 is rotatably installed inside it, with one end of the double-headed screw 5 extending into the concave connecting cover. The cover 4 is equipped with a handle for easy rotation of the double-ended screw 5. In addition, an external lug is fixedly installed on one side of the concave connecting cover 4, and a set screw is threaded on it. One end of the set screw abuts against the double-ended screw 5, which can fix the double-ended screw 5 and ensure the stability of use. Two connecting pieces 6 are threaded on the double-ended screw 5. The top of the two connecting pieces 6 passes through the processing table 3 and is fixedly connected to the corresponding straightening clamp 7. The connecting pieces 6 are slidably connected to the processing table 3. The two straightening clamps 7 pass through the support frame 8 and do not contact the inner wall of the support frame 8. In order to ensure the stability of the linear movement of the straightening clamps 7, two slide bars are fixedly installed inside the concave connecting cover 4. Two limit pieces are slidably installed on the two slide bars. The tops of the four limit pieces pass through the processing table 3 and are fixedly connected to the corresponding straightening clamp 7. The limit pieces are slidably connected to the processing table 3.

[0018] In this embodiment, the aforementioned pressing mechanism includes a first dual-axis cylinder 10 fixedly installed at the bottom of the top beam 9, and two connecting rods 11 fixedly installed on its output shaft. The bottom ends of the two connecting rods 11 are fixedly installed with the same pressing plate 12. The pressing plate 12 is relatively close to the cutting mechanism, so that the sealing strip can be pressed tightly at a position close to the cutting point, thereby improving the cutting stability.

[0019] In this embodiment, the aforementioned cutting mechanism includes a second dual-axis cylinder 13 fixedly installed on one side of the top beam 9. A fixed frame 14 is fixedly installed on its output shaft. A first rotary motor 15 is fixedly installed inside the fixed frame 14. Its output shaft extends outside the fixed frame 14 and a cutting blade 16 is fixedly installed thereon. The output shaft of the first rotary motor 15 is movably connected to one side of the fixed frame 14. The cutting blade 16 is located above one side of the processing table 3, that is, the distance between the cutting blade 16 and one side end face of the processing table 3 is relatively close. This allows for unobstructed cutting of the sealing strip and ensures that the cut end face protrudes from one side of the processing table 3, thus ensuring that the grinding mechanism can smoothly grind the cut end face.

[0020] In this embodiment, in order to stably install the grinding mechanism, a first support frame 1 and a second support frame 2 are fixedly installed at the bottom of the processing table 3. An external boss 17 is fixedly installed on the side of the first support frame 1 away from the second support frame 2. The aforementioned grinding mechanism includes a rodless cylinder 18 fixedly installed at the bottom of the external boss 17. A moving column 19 is fixedly installed on the slider of the rodless cylinder 18. The top of the moving column 19 extends above the external boss 17 and a carrying frame 20 is fixedly installed thereon. The moving column 19 is slidably connected to the external boss 17. A second rotary motor 21 is fixedly installed on the side of the carrying frame 20 near the processing table 3. A grinding disc 22 is fixedly installed on the output shaft of the second rotary motor 21. Two guide rails are fixedly installed on the top of the external boss 17. The same guide block is slidably installed on the two guide rails. The top of the guide block is fixedly connected to the carrying frame 20. Driven by the rodless cylinder 18, the grinding disc 22 can be brought to contact the end face of the sealing strip to form a grinding process.

[0021] In this embodiment, in order to automatically collect the cut end material, a material drop port 23 is provided on the external boss 17. The material drop port 23 is located below the cutting blade 16. A guide plate is fixedly installed on the side of the first support frame 1 away from the second support frame 2, and a receiving box is placed below the guide plate.

[0022] The working principle of the nylon sealing strip end processing device provided by this utility model is as follows: When processing the end of the nylon sealing strip, first place the nylon sealing strip on the processing table 3 and extend the end to be processed out of the processing table 3 so that it is below the cutting plate 16. Then rotate the double-headed screw 5 inside the concave connecting cover 4 to drive the two connecting plates 6 to move closer to each other on the processing table 3, so that the two straightening clamps 7 move closer to each other. At this time, the limiting plate slides synchronously on the slide bar to ensure that the straightening clamps 7 move stably until the sealing strip is clamped and straightened. Then tighten the set screw to fix the double-headed screw 5. Next, the pressing mechanism starts to work. The first dual-axis cylinder 10 drives the two connecting rods 11 to move downward, which in turn causes the pressing plate 12 to descend and press the sealing strip onto the processing table 3 to prevent displacement during subsequent processing. Then the cutting mechanism is started. The first rotary motor 15 drives the cutting blade 16 to rotate at high speed. Then the second dual-axis cylinder 13 pushes the fixed frame 14 to move down. When the cutting blade 16 contacts the sealing strip, it begins to cut its end. The waste generated by cutting falls through the discharge port 23 on the external boss 17 and enters the receiving box through the guide plate to form a collection. After cutting, the output shaft of the second dual-axis cylinder 13 is retracted to reset the cutting disc 16. Then, the grinding mechanism starts to operate. The rodless cylinder 18 drives the moving column 19 to move, so that the carrying frame 20 moves closer to the sealing strip along the guide rail. At the same time, the second rotary motor 21 drives the grinding disc 22 to rotate. When the grinding disc 22 contacts the cutting surface of the sealing strip, the end side of the cut sealing strip is ground to make it smoother and flatter. After grinding, the rodless cylinder 18 is activated to reset the grinding disc 22.

[0023] Then, the output shaft of the first dual-axis cylinder 10 is retracted to reset the lower pressure plate 12. The set screw is then unscrewed, and the double-ended screw 5 is rotated to loosen the sealing strip, which can then be removed. The remaining sealing strips are then processed in the same manner as described above.

[0024] Compared with related technologies, the nylon sealing strip end treatment equipment provided by this utility model has the following advantages: I. This utility model integrates straightening, fixing, cutting and grinding functions, and can complete multiple processing steps of the sealing strip end on the same equipment, reducing process change time and material handling costs, and improving overall processing efficiency; Second, the straightening clamp 7 driven by the double-headed screw 5 can accurately clamp and straighten the sealing strip. In conjunction with the lower pressure plate 12 driven by the first double-axis cylinder 10, the sealing strip can be firmly fixed, which effectively avoids the dimensional deviation caused by material displacement during the processing, and ensures the cutting and grinding accuracy. Moreover, the design of the double-headed screw 5 also makes the straightening clamp 7 applicable to the processing of nylon sealing strips of different specifications, and has strong versatility. Third, the waste generated during cutting can be directly fed into the receiving box through the discharge port 23 and the guide plate, which realizes the centralized collection of waste, maintains the cleanliness of the working environment, and reduces the cost of manual cleaning.
