[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-6 A high-precision silicone rubber tube cutting machine includes a workbench 1 and a control box 2. A conveying device 3 and a cutting mechanism 4 are provided on the workbench 1, and a guide mechanism 5 is provided on the surface of the control box 2. The silicone rubber tube is conveyed to the cutting mechanism 4 through the conveying device 3 under the limit guidance of the guide mechanism 5 for automatic tube cutting.

[0036] like Figure 2 、 5 As shown, the conveying device 3 includes a support plate 31, which is fixedly mounted on the workbench 1. An adjustment plate 32 is provided above the support plate 31, and an adjustment assembly 33 for adjusting its height is provided on the adjustment plate 32. Two crawler conveyors 34 are provided on the front sides of the support plate 31 and the adjustment plate 32, which are opposite each other. The two crawler conveyors 34 are respectively mounted on the support plate 31 and the adjustment plate 32, forming a mechanism for clamping and advancing the silicone rubber tube. This design ensures that the silicone rubber tube is in a stable position during transportation, reduces swinging and offsetting during movement, and improves cutting accuracy. The adjustment plate 32 is located above the support plate 31 and can be adjusted in height through the adjustment assembly 33. In this way, the gap can be adjusted according to the silicone rubber tubes of different sizes, ensuring a smooth and accurate transportation process.

[0037] Specifically, the adjustment assembly 33 includes a connecting block 331 disposed above the adjustment plate 1 32. Support rods 332 are fixedly connected to both sides of the bottom of the connecting block 331. The support rods 332 extend through and below the adjustment plate 1 32, where they are fixedly connected to the support plate 31. The support rods 332 are slidably connected to the adjustment plate 1 32. A threaded rod 333 is interspersed through the connecting block 331 and positioned between the two support rods 332. The threaded rod 333 extends through and below the adjustment plate 1 32, where it is rotationally connected to the support plate 31. The threaded rod 333 is threadedly connected to the adjustment plate 1 32. By rotating the threaded rod 333 and cooperating with the limit guide of the support rod 332, the position of the adjustment plate 1 32 can be precisely controlled, thereby adjusting the spacing between the crawler conveyors 34.

[0038] like Figure 3 、 6 As shown, the cutting mechanism 4 includes a fixed plate 41, which is fixed to the side of the support plate 31. A cutting base block 42 is installed on the top of the fixed plate 41, corresponding to the top of the crawler conveyor 34. A cutting die 43 is mounted on the cutting base block 42, and a cutter assembly 45 is installed above the cutting die 43, corresponding to the cutter 44. A hydraulic cylinder 46 is inserted through the fixed plate 41 and fixedly connected to it. The cylinder rod of the hydraulic cylinder 46 is connected to the cutter assembly 45. When the silicone rubber tube is conveyed into the cutting die 43 by the conveying device 3 and reaches the required length, the hydraulic cylinder 46 drives the cutter assembly 45 to quickly press down, completing the cutting. This power transmission method ensures the strength and speed of the cutting process, achieving a clean and fast cutting effect.

[0039] In addition, the cutting die 43 is provided with a bayonet 431 adapted to the cutting base block 42. The bottom of the bayonet 431 is provided with a tube opening 432 adapted to the diameter of the silicone rubber tube. The cutting die 43 is fixed to the cutting base block 42 via the bayonet 431. This design not only ensures cutting accuracy but also facilitates replacement of the cutting die 43 according to pipes of different diameters, improving the applicability and flexibility of the equipment.

[0040] A bracket 433 is provided above the cutting die 43. The bracket 433 is fixedly mounted on the fixing plate 41. A tightening bolt 434 is threadedly connected to the bracket 433. The bottom end of the tightening bolt 434 abuts against the surface of the cutting die 43. The tightening bolt 434 allows the fixing force between the cutting die 43 and the cutting base 42 to be adjusted, which is crucial for maintaining stability during the cutting process.

[0041] Furthermore, the cutter assembly 45 includes a blade holder 451. The bottom of the blade holder 451 is a notch corresponding to the cutout 44. The blade holder 451 is provided with two mounting slots 452, one on either side of the notch. A cutter 453 is mounted on the blade holder 451. The cutter 453 plugs into the two mounting slots 452 and is positioned over the notch, corresponding to the cutout 44. The bottom outer side of the blade holder 451 is fixedly connected to the hydraulic cylinder 46. The plug-in design of the cutter 453 makes replacement of the cutter 453 simple and quick. When the cutter 453 becomes worn, the operator can quickly replace it without complicated tools or lengthy downtime.

[0042] Furthermore, a guide bucket 47 is installed on the outer side of the fixing plate 41 corresponding to the cutting base block 42. After the cutting is completed, the guide bucket 47 can effectively guide and collect the cut silicone rubber tube.

[0043] like Figure 4 As shown, the guide mechanism 5 includes a first guide component 51 in the control box 2, a fixed wheel 52 is provided on one side of the first guide component 51, a pressure wheel 53 is provided on the fixed wheel 52, the pressure wheel 53 is rotatably connected to a support plate 531, the support plate 531 is rotatably connected to the control box 2 through a rotating shaft, a torsion spring 532 is sleeved on the rotating shaft on the support plate 531, one end of the torsion spring 532 is connected to the support plate 531 by a bolt, and the other end is connected to the control box 2 by a bolt. An adjusting wheel 54 is provided on one side of the fixed wheel 52, and an adjusting plate 2 541 is connected to the adjusting wheel 54. An adjusting slot 542 is opened on the control box 2, and the adjusting plate 2 541 is slidably connected in the adjusting slot 542 by bolts. The control box 2 is equipped with a mounting block 55, on which two limit posts 56 are fixedly mounted. A limit shaft 57 is provided on one side of the mounting block 55. A second guide assembly 58 is mounted on the left side of the support plate 31. A limit rod 59 is provided between the crawler conveyor 34 and the second guide assembly 58. The limit rod 59 is fixed to the support plate 31. The first guide assembly 51 and the second guide assembly 58 each include a fixed guide block 6 and two guide posts 7 with adjustable spacing. The two guide posts 7 are bolted to the fixed guide block 6. The adjustable design of the guide posts 7 allows for the use of silicone rubber tubes of varying diameters.

[0044] The silicone rubber tube is clamped between the two guide posts 7 of the first guide assembly 51, then passes through the fixed wheel 52 and the adjusting wheel 54, wraps around the bottom of the limit shaft 57, passes between the two limit posts 56, between the two guide posts 7 of the second guide assembly 58, and finally is sent to the two crawler conveyors 34 through the limit rod 59, ensuring that the silicone rubber tube can be accurately guided and positioned. Among them, the pressure wheel 53 presses the fixed wheel 52 with the help of the force of the torsion spring 532, thereby applying a moderate downward pressure on the silicone rubber tube, ensuring that the friction between it and the fixed wheel 52 is appropriate to avoid sliding or offset. The second adjustment plate 541 is combined with the adjustment slot 542 in the control box 2, and the height adjustment of the adjusting wheel 54 is achieved through the sliding connection of the bolt, further enhancing the ability of the guide mechanism 5 to adapt to different conditions.
