Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a sealing strip cutting device. Background Technology

[0002] The cutting device is used to cut the sealing strip. It consists of a machine base, mounting frame, mounting block, electric push rod assembly, U-shaped frame, pressure plate, power wheel, guide roller, and cutting blade. When using the cutting device, the sealing strip is conveyed and positioned smoothly by the coordinated rotation of the power wheel and guide roller on the mounting block driven by a motor. This smoothly conveys the sealing strip placed on the machine base to the cutting position while simultaneously limiting the strip horizontally to prevent deviation. The sealing strip is fixed and pressed in place by the first electric push rod on the U-shaped frame, which drives the pressure plate to fix the strip at multiple points before cutting, preventing deformation or unevenness of the cut due to strip movement during the cutting process. The cutting blade is driven vertically downwards by the second electric push rod on the mounting frame to complete the cutting action. The cut strip is automatically conveyed to the collection area via a conveyor belt.

[0003] The inventors discovered in their daily work that when the cutting device is in use, the cutting blade becomes dull due to prolonged cutting of the sealing strip. This necessitates disassembly, grinding, and reinstallation of the cutting blade. However, during installation, workers need to lift the cutting blade to ensure that the mounting holes on the connecting plate and the moving rod are horizontally and vertically aligned before inserting bolts for fixation. But if workers lift the blade while installing, the mounting holes are prone to misalignment, potentially requiring realignment and impacting installation efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in actual use, due to the prolonged cutting of the sealing strip by the cutting blade, the cutting edge of the blade becomes dull, requiring disassembly, grinding, and reinstallation of the cutting blade. However, when installing the cutting blade, the worker needs to hold the cutting blade up to keep the mounting holes on the connecting plate and the moving rod horizontally and vertically aligned before inserting bolts for fixing. But if the worker holds the blade up while installing, the mounting holes are prone to misalignment, which may lead to the need for realignment and installation, affecting installation efficiency. Therefore, a sealing strip cutting device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sealing strip cutting device, comprising a machine base, a guide roller rotatably connected to the inner wall of the machine base via bearings, an mounting block, a U-shaped frame, and a mounting bracket fixedly connected to the upper end of the machine base, a rotatable power wheel between two mounting blocks, a second electric push rod mounted on the upper end of the mounting bracket, a moving rod slidably connected to the inner wall of the mounting bracket, the moving rod and the second electric push rod being fixed, a connecting plate being provided below the moving rod, a cutting blade being fixedly connected to the lower end of the connecting plate, a pre-fixing assembly being provided between the connecting plate and the moving rod, the pre-fixing assembly comprising a plurality of evenly distributed positioning tubes fixedly connected to the upper end of the connecting plate, the positioning tubes being inserted into the moving rod, and the arc surface of the positioning tubes being provided with protrusions.

[0006] The effect achieved by the above components is as follows: by setting a pre-fixing component, when installing the cutting blade onto the moving rod, the connecting plate is dragged so that the positioning tube is inserted into the moving rod, thereby pre-fixing the connecting plate to the moving rod, and then fixing it with bolts, thereby minimizing the impact on reinstallation efficiency due to misalignment of the mounting holes.

[0007] Preferably, a pin is slidably inserted into the arc surface of the positioning tube, the pin is inserted into the moving rod, and a sliding surface is provided at the left end of the pin.

[0008] The effect achieved by the above components is as follows: when the positioning tube is inserted into the moving rod, the sliding surface of the pin contacts the moving rod, causing the pin to be squeezed and pushed back into the positioning tube, thus compressing the reset mechanism. When the positioning tube is fully inserted into the moving rod, the reset mechanism resets, causing the pin to be inserted into the moving rod, thereby assisting the positioning tube to be fixed inside the moving rod.

[0009] Preferably, a spring is fixedly connected to the right end of the pin, and the other end of the spring is fixed to the positioning tube.

[0010] The effect achieved by the above components is as follows: when the positioning tube is inserted into the moving rod, the sliding surface of the pin contacts the moving rod, causing the pin to be squeezed and pushed back into the positioning tube, thereby compressing the spring.

[0011] Preferably, a pull rope is fixedly connected to the right end of the pin, and the pull rope passes through the positioning tube and the connecting plate.

[0012] The effect achieved by the above components is as follows: pulling the pull rope causes the pin to retract into the positioning tube, and then dragging the connecting plate causes the positioning tube to separate from the moving rod.

[0013] Preferably, the arc surface of the guide roller is provided with an adjustment component, the adjustment component includes limiting rings disposed on both sides of the arc surface of the guide roller, and the arc surface of the guide roller is provided with a plurality of evenly distributed threaded holes.

[0014] The effect achieved by the above components is as follows: the position of the moving limit ring is moved, and then the limit ring is fixed to the threaded hole by the locking mechanism, thereby adjusting the distance between the two limit rings and thus adapting to sealing strips of different widths.

[0015] Preferably, the arc surface of the limiting ring is threaded with a screw, and the screw is adapted to the threaded hole.

[0016] The effect achieved by the above components is to tighten the screws to make them threaded into the threaded hole.

[0017] Preferably, a first electric push rod is installed at the upper end of the U-shaped frame, and a pressure plate is fixedly connected to the output end of the first electric push rod.

[0018] The effect achieved by the above components is as follows: the controller activates the first electric push rod, causing the pressing plate to descend and press against the sealing strip for a limit stop.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] In this invention, by setting a pre-fixing component, when installing the cutting blade onto the moving rod, the connecting plate is dragged so that the positioning tube is inserted into the moving rod, thereby pre-fixing the connecting plate to the moving rod. Then, bolts are used for fixing, thus minimizing the impact on reinstallation efficiency due to misalignment of the mounting holes. This solves the problem that because the cutting blade has been cutting the sealing strip for a long time, the cutting blade edge becomes dull, requiring disassembly and grinding before reinstallation. However, when installing the cutting blade, the worker needs to hold the cutting blade to keep the mounting holes on the connecting plate and the moving rod horizontally and vertically aligned before inserting bolts for fixing. But if the worker holds the blade while installing, the mounting holes are prone to misalignment, which may lead to the need for realignment and affect installation efficiency.

[0028] Reference Figure 1 and Figure 3 As shown, this utility model provides a technical solution: a sealing strip cutting device includes a machine base 1. The inner wall of the machine base 1 is provided with a guide roller 4 rotatably connected by a bearing. The upper end of the machine base 1 is fixedly connected with a mounting block 5, a U-shaped frame 7, and a mounting bracket 9. A rotatable power wheel 6 is provided between the two mounting blocks 5. A second electric push rod 10 is installed on the upper end of the mounting bracket 9. A moving rod 11 is slidably connected to the inner wall of the mounting bracket 9. The moving rod 11 and the second electric push rod 10 are fixed. A connecting plate 12 is provided below the moving rod 11. A cutting blade 13 is fixedly connected to the lower end of the connecting plate 12. A pre-fixing component 2 is provided between the connecting plate 12 and the moving rod 11. A first electric push rod 8 is installed on the upper end of the U-shaped frame 7. A pressing plate 14 is fixedly connected to the output end of the first electric push rod 8. The first electric push rod 8 is activated by a controller, causing the pressing plate 14 to move downward and press down on the sealing strip for limiting.

[0029] Reference Figure 4As shown, in this embodiment: the pre-fixing component 2 includes a plurality of evenly distributed positioning tubes 21 fixedly connected to the upper end of the connecting plate 12. The positioning tubes 21 are inserted into the moving rod 11. The arc surface of the positioning tubes 21 is provided with protrusions. By setting the pre-fixing component 2, when the cutting blade 13 is installed on the moving rod 11, the connecting plate 12 is dragged so that the positioning tubes 21 are inserted into the moving rod 11, thereby pre-fixing the connecting plate 12 to the moving rod 11. Then, bolts are used for fixing, thereby minimizing the impact on reinstallation efficiency due to misalignment of the mounting holes. The arc surface of the positioning tubes 21 is slidably inserted with pins 22. The pins 22 are inserted into the moving rod 11. The left end of the pins 22 has a sliding surface 23. When the positioning tubes 21 are inserted into the moving rod 11, the sliding surface 23 of the pins 22 contacts the moving rod 11, so that the pins 22... The pin 22 is pushed back into the positioning tube 21 by the compression, which compresses the reset mechanism. When the positioning tube 21 is fully inserted into the moving rod 11, the reset mechanism resets, allowing the pin 22 to be inserted into the moving rod 11, thus helping to fix the positioning tube 21 into the moving rod 11. A spring 24 is fixedly connected to the right end of the pin 22, and the other end of the spring 24 is fixed to the positioning tube 21. When the positioning tube 21 is inserted into the moving rod 11, the sliding surface 23 of the pin 22 contacts the moving rod 11, causing the pin 22 to be pushed back into the positioning tube 21 by the compression, which compresses the spring 24. A pull rope 25 is fixedly connected to the right end of the pin 22. The pull rope 25 passes through the positioning tube 21 and the connecting plate 12. Pulling the pull rope 25 causes the pin 22 to retract into the positioning tube 21, and then dragging the connecting plate 12 causes the positioning tube 21 to separate from the moving rod 11.

[0030] Reference Figure 2 As shown in this embodiment: the arc surface of the guide roller 4 is provided with an adjustment component 3. The adjustment component 3 includes a limiting ring 31 disposed on both sides of the arc surface of the guide roller 4. The arc surface of the guide roller 4 is provided with a plurality of evenly distributed threaded holes 32. The position of the limiting ring 31 is moved, and then the limiting ring 31 is fixed to the threaded hole 32 by a locking mechanism, thereby adjusting the distance between the two limiting rings 31, and thus adapting to sealing strips of different widths. The arc surface of the limiting ring 31 is threaded with a screw 33, which is adapted to the threaded hole 32. Tightening the screw 33 makes it threadedly fixed to the threaded hole 32.

[0031] Working principle:

[0032] When using the cutting device (the cutting device can be the sealing strip cutting machine TH-L), the sealing strip is conveyed and positioned as follows: The motor drives the power wheel 6 on the mounting block 5 and the guide roller 4 to rotate in tandem, smoothly conveying the sealing strip placed on the machine base 1 to the cutting position. Simultaneously, the strip is horizontally limited to prevent deviation. For fixing and clamping, the first electric push rod 8 on the U-shaped frame 7 drives the clamping plate 14, fixing the strip at multiple points before cutting to avoid deformation or unevenness of the cut due to strip movement during the cutting process. For precise cutting, the cutting blade 13 is driven vertically downwards by the second electric push rod 10 on the mounting frame 9 (the electric push rod can be the DTZ model) to complete the cutting action. For finished product collection, the cut strip is automatically conveyed to the collection area via a conveyor belt. When installing the cutting blade 13 onto the moving rod 11, the connecting plate 12 is dragged, causing the positioning tube 21 to insert into the moving rod 11, thereby connecting the strip. The connecting plate 12 is pre-fixed to the moving rod 11 and then fixed with bolts to minimize the impact of misalignment of the mounting holes on reinstallation efficiency. When the positioning tube 21 is inserted into the moving rod 11, the sliding surface 23 of the pin 22 contacts the moving rod 11, causing the pin 22 to be squeezed and pushed back into the positioning tube 21, thus compressing the spring 24. When the positioning tube 21 is fully inserted into the moving rod 11, the spring 24 returns to its original position, allowing the pin 22 to be inserted into the moving rod 11, thus assisting in fixing the positioning tube 21 into the moving rod 11. Pulling the pull rope 25 causes the pin 22 to retract into the positioning tube 21. Then, dragging the connecting plate 12 separates the positioning tube 21 from the moving rod 11, moves the position of the limiting ring 31, and then screws 33 to fix it to the threaded hole 32, thus fixing the limiting ring 31 to the threaded hole 32, thereby adjusting the distance between the two limiting rings 31 to accommodate sealing strips of different widths.
