All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0023] Reference Figure 1-Figure 4 The utility model provides an auxiliary fixing mechanism of an aluminum hose cap twisting machine, comprising an upper fixing plate 1, the top of the upper fixing plate 1 is rotatably connected with a connecting shaft 14, one end of the connecting shaft 14 passes through the upper fixing plate 1 and is provided with a die head 2, and the die head 2 and the connecting shaft 14 are fixed by a clamping mechanism, two guide rails 12 are welded to the bottom of the upper fixing plate 1, multiple sides of the two guide rails 12 are slidably connected with a lower connecting plate 3, and the guide rails 12 and the lower connecting plate 3 are fixed by bolts, one side of the lower connecting plate 3 is provided with a placement groove 5, and the two ends of the lower connecting plate 3 are fixed to the lower connecting plate 3. Sliding holes 17 are provided on both sides, and sliding rods 7 are slidably connected in the sliding holes 17. A clamping plate 6 is fixed to one end of the sliding rod 7 by bolts. A power mechanism for driving the sliding rod 7 to move is provided on one side of the lower connecting plate 3. The end of the hose is put on the mold head 2, and then the position of the lower connecting plate 3 is adjusted. The lower connecting plate 3 is fixed with bolts, and the sliding rod 7 is driven to move by the power mechanism, so that the two clamping plates 6 clamp the hose and fix the hose. At the same time, the end of the hose can be prevented from tilting, which is convenient for twisting the cap on the end of the hose, thereby improving the processing efficiency of the device.

[0024] Among them, the power mechanism includes a slide 10, which is slidably connected to one side of the lower connecting plate 3. Two guide grooves 9 are opened on the top of the slide 10. The tops of the two slide rods 7 are fixed with fixed columns 8 by bolts, and the fixed columns 8 slide in the guide grooves 9. One side of the lower connecting plate 3 is rotatably connected with a screw rod 16, and one end of the screw rod 16 passes through the slide 10 and is threadedly connected to the slide 10. The screw rod 16 is rotated, and the screw rod 16 drives the slide 10 to slide, so that the guide groove 9 squeezes the fixed column 8 to slide in the guide groove 9, and then pushes the slide rod 7 to move. Manual adjustment can reduce the factory's investment cost and facilitate maintenance.

[0025] Among them, the locking mechanism includes two elastic plates 19, one end of the two elastic plates 19 is welded on both sides of the connecting shaft 14 respectively, a socket 18 is opened on the top of the mold head 2, grooves 20 are opened on both sides of the socket 18, and the elastic plate 19 is stuck in the groove 20. The elastic plate 19 is made of a leaf spring. When it is necessary to twist the cap on hoses with different inner diameters, the mold head 2 is pulled out from the connecting shaft 14 to disengage the connecting shaft 14 from the socket 18, so that different mold heads 2 can be replaced. In the process of pulling out the mold head 2, the groove 20 will squeeze the elastic plate 19 to deform, so that the elastic plate 19 is disengaged from the groove 20, thereby improving the versatility of the device.

[0026] There are multiple installation grooves on the opposite sides of the two clamping plates 6, and auxiliary rollers 4 are rotatably connected in the installation grooves to reduce the friction between the clamping plates 6 and the hose, so that the hose can be easily rotated, thereby improving the protection effect of the hose.

[0027] Among them, two positioning grooves 21 are opened on the top of the mold head 2, and the positioning grooves 21 are connected with the socket 18. Positioning blocks 22 are welded on both sides of the connecting shaft 14, and the positioning blocks 22 are plugged into the positioning grooves 21. During the rotation of the connecting shaft 14, force is avoided between the elastic plate 19 and the groove 20, thereby improving the service life of the device.

[0028] Among them, a scale 11 is provided on one side of the two guide rails 12 to check the position of the adjusted lower connecting plate 3, which is convenient for capping different hoses. Two fixing blocks 13 are welded on one side of the two guide rails 12, and the fixing blocks 13 are fixed to the upper fixing plate 1, thereby strengthening the fixation between the guide rails 12 and the upper fixing plate 1, making the guide rails 12 and the upper fixing plate 1 more firmly fixed. Mounting seats 15 are welded on both sides of the upper fixing plate 1, so that the device can be installed on the capping machine.

[0029] The working principle of the utility model is as follows: first, the mechanism is installed on the cap-twisting machine through the mounting seat 15, and the connecting shaft 14 is connected to the servo motor on the cap-twisting machine. When the cap of the hose needs to be twisted, a suitable mold head 2 is put on the connecting shaft 14, and then the end of the hose is put on the mold head 2, and then the position of the lower connecting plate 3 is adjusted, and the lower connecting plate 3 is fixed with bolts, and the screw rod 16 is rotated. The screw rod 16 drives the slide 10 to slide, so that the guide groove 9 squeezes the fixed column 8 to slide in the guide groove 9, and then pushes the slide bar 7 to move. The movement of the slide bar 7 drives the two clamps 6 to move, so that the two clamps 6 clamp the hose and fix the hose. At the same time, it can prevent the end of the hose from tilting, which is convenient for the cap-twisting operation on the end of the hose, and improves the processing efficiency of the device.
