[0002] Nylon thermal break strips are a key component in thermally broken aluminum windows and doors, and their quality and precision directly affect the thermal insulation performance and overall quality of the windows and doors. During the production and processing of nylon thermal break strips, long strips need to be cut into short strips of specific lengths according to actual needs.

In this embodiment, to improve cutting accuracy and automatically push the nylon heat insulation strip onto the cutting surface, two side plates are fixedly installed on the top inner wall of the C-shaped frame 1. A single one-way adjusting screw 8 is rotatably mounted on each side plate. A stop plate 9 is threaded onto the one-way adjusting screw 8, and the bottom of the stop plate 9 contacts the top of the two placement platforms 3. A rodless cylinder 18 is fixedly installed inside the mounting opening 2, and a transverse sliding bar 19 is fixedly installed on its slider. A buffer spring 21 is fixedly installed on the side of the transverse sliding bar 19 near the C-shaped frame 1. A support block 20 is fixedly installed on the end of the buffer spring 21 near the C-shaped frame 1. A push rod 22 is fixedly installed on the top of the support block 20. The surface is slightly higher than the top end face of the shelf 3, and the push rod 22 is located between the two shelves 3. In addition, a first scale 10 is fixedly installed on the top of the C-shaped frame 1. The zero mark of the first scale 10 is the same as the cutting axis of the cutting blade 6, making the adjustment process visual and simplified, and the numerical calculation convenient. A marker 11 is fixedly installed on the top of the abutment plate 9. The top of the marker 11 passes through the top of the C-shaped frame 1 and extends to the bottom of the first scale 10. The marker 11 is movably connected to the top of the C-shaped frame 1. The same limiting bar is fixedly installed on the two side plates. The limiting bar passes through the abutment plate 9 and is slidably connected to the abutment plate 9. A first set screw is threaded on the limiting bar, and its end abuts against the limiting bar. An anti-deviation unit is provided on one outer wall of the C-shaped frame 1 to prevent the nylon thermal insulation strip from shifting. This anti-deviation unit includes a fixed boss 12 fixedly installed on the outer wall of the C-shaped frame 1 away from the abutment plate 9. A double-sided bracket 13 is fixedly installed at the bottom of the fixed boss 12, and a bidirectional adjusting screw 14 is rotatably installed inside it. Two connecting pieces 15 are threaded onto the bidirectional adjusting screw 14. An installation strip 16 is fixedly installed at the bottom of each of the two connecting pieces 15. Both installation strips 16 pass through the installation opening 2 but do not contact the inner wall of the installation opening 2. Multiple limiting cylinders 17 are rotatably installed at the bottom of each of the two installation strips 16. The bottom end face of the limiting cylinder 17 is slightly higher than the top end face of the platform 3. The mechanism is adjusted by rotating... The spacing of the limiting cylinders 17 can be adjusted according to the width of the heat insulation strip by using the bidirectional adjusting screw 14. In addition, in order to improve the adjustment accuracy, a second scale is fixedly installed on the top inner wall of the double-sided bracket 13. The top of the two connecting pieces 15 is fixedly installed with a pointer, and the two pointers are located below the second scale. The zero mark of the second scale is located in the middle. In order to ensure that the movement of the mounting strip 16 is linear, a slide rail is fixedly installed at the bottom of the fixed boss 12. Two sliders are slidably installed on it.

The pusher unit includes a single-axis cylinder 23 fixedly installed on one side of the C-shaped frame 1, and a pusher plate 24 is fixedly installed on its output shaft. The pusher plate 24 is located above the platform 3. Furthermore, a frame is provided on one side of the C-shaped frame 1, and a receiving box is placed inside the frame. A guide plate is fixedly installed on the side of the platform 3 near the receiving box. The bottom of the guide plate extends to the top of the receiving box. By extending the output shaft of the single-axis cylinder 23, the pusher plate 24 can push the cut heat insulation strips onto the guide plate, and finally they fall into the receiving box.

[0018] The working principle of the continuous cutting equipment for nylon thermal insulation strips provided by this utility model is as follows: During the cutting operation, the operator needs to rotate the one-way adjusting screw 8 installed on the two side plates according to the preset cutting length of the nylon heat insulation strip. Since the one-way adjusting screw 8 is threadedly connected to the abutment plate 9, and the abutment plate 9 is restricted from rotating by the through limit bar, the rotation of the one-way adjusting screw 8 will drive the abutment plate 9 to move horizontally along the top surface of the platform 3. During the adjustment process, the distance between the abutment plate 9 and the cutting blade 6 (i.e., the cutting length) is determined by comparing the scale rod 11 with the first scale 10. After the adjustment is completed, the first set screw on the limit bar is tightened to fix the position of the abutment plate 9 and prevent it from shifting during the cutting process. Then, according to the width of the nylon heat insulation strip, rotate the bidirectional adjusting screw 14. The two connecting pieces 15 on the bidirectional adjusting screw 14 will move closer or further away synchronously with the rotation of the screw because the threads are turned in opposite directions. The mounting strip 16 at the bottom of the connecting piece 15 will drive the bottom rotating mounting limit cylinder 17 to move synchronously. By comparing the scale head with the second scale, the distance between the two limit cylinders 17 is matched with the width of the heat insulation strip. After adjustment, tighten the second set screw on the two sliders to fix the position of the mounting strip 16 and complete the anti-deviation positioning. Subsequently, the nylon heat insulation strip is placed on top of the two platforms 3, and the rodless cylinder 18 is activated. Its slider drives the transverse strip 19 to move towards the direction of the C-shaped frame 1. When the push rod 22 contacts the heat insulation strip, it pushes it and finally pushes it to the position of contacting the abutment plate 9. During the movement, the limiting cylinders 17 on both sides limit the heat insulation strip laterally to prevent it from deviating in the width direction and ensure that the heat insulation strip is always conveyed along the preset path. At this time, the part of the heat insulation strip to be cut is located directly below the cutting blade 6. Next, the dual-axis cylinder 4 in the cutting unit is started, and its output shaft pushes the connecting plate 5 to move downward. The two buffer rods at the bottom of the connecting plate 5 drive the compaction plate 7 to contact the top of the heat insulation strip first. As the connecting plate 5 continues to move downward, the compaction spring on the buffer rod is compressed, and the compaction plate 7 applies stable pressure to the heat insulation strip, pressing it tightly onto the platform 3 to prevent displacement during cutting. Subsequently, the cutting blade 6 at the bottom of the connecting plate 5 passes through the clearance on the compaction plate 7 and continues to cut downward into the heat insulation strip, and finally enters the blade groove at the top of the platform 3 to complete one cut. After the cut is completed, the dual-axis cylinder 4 drives the connecting plate 5, the cutting blade 6 and the compaction plate 7 to reset synchronously. The compaction spring rebounds, causing the compaction plate 7 to detach from the heat insulation strip first, which facilitates subsequent material removal. After cutting, the single-axis cylinder 23 in the pusher unit is started. Its output shaft pushes the pusher plate 24 to move closer to the guide plate, pushing the cut heat insulation strip out of the platform 3. The pushed heat insulation strip slides down the guide plate and finally falls into the receiving box, realizing automatic material collection. After the material is pushed, the single-axis cylinder 23 drives the pusher plate 24 to reset, and at the same time, the rodless cylinder 18 is started. Its slider drives the transverse strip 19 to continue moving, forming a pushing force on the remaining heat insulation strip until its end is pushed to contact the abutment plate 9. Then, the above cutting process is repeated to achieve continuous operation. The buffer spring 21 can provide buffer when the heat insulation strip is obstructed, avoiding hard collision damage to the equipment or materials.

[0019] Compared with related technologies, the continuous cutting equipment for nylon thermal insulation strips provided by this utility model has the following advantages: I. This utility model can accurately adjust the cutting length by cooperating with the one-way adjusting screw 8 and the abutment plate 9, and with the cooperation of the scale rod 11 and the first scale 10, thereby improving the cutting accuracy. Furthermore, subsequent cuts do not require repositioning, thus improving convenience. Second, this utility model can automatically push the nylon heat insulation strip to contact the abutment plate 9 through the rodless cylinder 18 and push rod 22, without the need for manual positioning, making the work more continuous, improving work efficiency and significantly improving safety performance. Third, the anti-deviation unit of this utility model can use the limiting cylinder 17 to form an anti-deviation effect on the heat insulation strip, further improving the cutting accuracy. In addition, the compaction plate 7 and the compaction spring press the heat insulation strip tightly, and the cooperation between the knife groove of the platform 3 and the cutting knife 6 prevents material movement and knife deviation, reducing the defective product rate.
