Description

Technical Field

[0001] This utility model relates to the field of tube making machine technology, specifically to a tube making machine aluminum-plastic sheet trimming device. Background Technology

[0002] The tube-making machine uses welding to form aluminum-plastic flexible tubes from aluminum-plastic sheets. To ensure the diameter of the aluminum-plastic flexible tube, the aluminum-plastic sheets usually need to be trimmed before welding. For example, Chinese patent CN213617002U, entitled "A Tube-Making Machine Feeding and Trimming Mechanism," includes a mounting vertical plate, an upper support plate connected to the mounting vertical plate, and a side support plate connected to the end of the upper support plate. A screw rod 1 and a screw rod 2 are rotatably connected between the side support plate and the mounting vertical plate, and the screw rod 1 and screw rod 2 are arranged side-by-side. The screw rod 1 and screw rod 2 are respectively threaded... The device is equipped with a first blade holder and a second blade holder, both with blades mounted below them. The first and second blade holders slide via a guide rail assembly. A servo motor is connected to one side of the mounting vertical plate. The output of the servo motor passes through the mounting vertical plate and drives screws one and two via a gear set. The servo motor drives the adjustment of the blade position. However, during the cutting process, because the aluminum-plastic sheet has no support underneath, the aluminum-plastic sheet is subjected to resistance from the blades on both sides. The aluminum-plastic sheet tends to be arc-shaped during the cutting process, resulting in a larger width of the cut aluminum-plastic sheet and thus a larger diameter of the manufactured aluminum-plastic hose.

[0003] The technical problem to be solved by this utility model is to provide an aluminum-plastic sheet trimming device for a tube making machine, which addresses the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A tube-making machine for cutting aluminum-plastic sheet edges includes a base plate with support plates connected to both sides. A mounting shaft passes through the support plates, with both ends of the mounting shaft extending out of the support plates.

One end of the torsion spring is connected to the rotating arm, and the other end is connected to the support plate. An adjusting shaft is connected to the side of the rotating arm closest to the base plate. An adjusting block is mounted on the adjusting shaft. A wheel groove is machined on the bottom of the adjusting block, and a rubber-coated wheel is mounted in the wheel groove. A wheel axle passes through the middle of the rubber-coated wheel, and wheel seats are connected to both ends of the wheel axle. Screws are mounted on both sides of the wheel seats, and springs are sleeved on the upper ends of the screws. A blade seat is mounted on the side of the adjusting block and is rotatably connected to the adjusting block. A blade is mounted on the blade seat, and a tension spring is provided between the blade seat and the adjusting block.

[0006] Furthermore, an operating shaft is connected between the rotating arm and the side away from the base plate.

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0018] like Figures 1-4As shown, a tube-making machine for cutting aluminum-plastic sheet edges includes a base plate 1, with support plates 2 connected to both sides of the base plate 1. Mounting bosses 3 are machined on the bottom of the support plates 2, and the mounting bosses 3 are connected to the base plate 1 by screws. A mounting shaft 4 passes through the support plates 2, with both ends of the mounting shaft 4 extending out of the support plates 2. A washer 5, a rotating arm 6, and a torsion spring 7 are connected to the extended ends of the mounting shaft 4. A nut and a flat washer are installed at the end of the extended ends of the mounting shaft 4 to block the torsion spring 7. Two connecting feet are provided at both ends of the torsion spring 7; one connecting foot connects to the connecting hole on the rotating arm 6, and the other connecting foot connects to the connecting hole on the support plate 2.

[0019] An adjusting shaft 8 is connected between the rotating arms 6 on the side closer to the base plate 1, and an operating shaft 9 is connected between the rotating arms 6 on the side farther from the base plate 1. An adjusting block 10 is provided on the adjusting shaft 8, and a locking screw 11 is connected to the upper end of the adjusting block 10. A locking groove 12 is machined on the surface of the adjusting shaft 8. After the locking screw 11 is tightened, its end is inserted into the locking groove 12 to fix the adjusting block 10.

[0020] The bottom of the adjusting block 10 is machined with a wheel groove, and a rubber-coated wheel 13 is arranged in the wheel groove. A wheel axle 14 passes through the middle of the rubber-coated wheel 13. Wheel seats 15 are connected to both ends of the wheel axle 14. Bearings are arranged in the wheel seats 15. The two ends of the wheel axle are connected to the bearings in the wheel seats 15. Screws 16 are arranged on both sides of the wheel seats 15. Springs 17 are sleeved on the upper ends of the screws 16. The springs 17 cause the rubber-coated wheel to press against the aluminum-plastic sheet on the base plate 1. A blade seat 18 is arranged on the side of the adjusting block 10. The blade seat 18 is rotatably connected to the adjusting block 10 by a pin. A blade 19 is installed on the blade seat 18. A tension spring 20 is arranged between the blade seat 18 and the adjusting block 10. Connecting screws 21 are installed on the adjusting block 10 and the blade seat 18. The two ends of the tension spring 20 are hooked on the connecting screws 21 of the adjusting block 10 and the blade seat 18, respectively.

[0021] When the tube making machine is working, adjust the position of the adjusting block 10 to determine the cutting width, then lock the adjusting block 10 with the locking screw 11, and rotate the rotating arm 6 by the operating shaft 9 so that the aluminum-plastic sheet passes through the surface of the base plate 1. After the operating shaft 9 is released, the rotating arm rotates back to its original position under the action of the torsion spring. At the same time, the rubber-coated wheel 13 presses the aluminum-plastic sheet on the surface of the base plate 1 under the action of the spring 17. Then the tension spring 20 is hung. The tension of the tension spring 20 enables the blade to cut through the aluminum-plastic sheet.

[0022] This utility model is not limited to the embodiments described. Those skilled in the art can still make some modifications or changes without departing from the spirit and scope of this utility model. Therefore, the scope of protection of this utility model shall be determined by the scope defined in the claims.
