The second connection plate 732 and the fourth connection plate 734 are both vertically arranged, and the first connection plate 731, the third connection plate 733 and the fifth connection plate 735 are all horizontally arranged.

[0055] like Figure 7 and 8 As shown, when the pressing mechanism 5 presses the local hot-melt braided sleeve for laser cutting, the hot-melt braided sleeve located at the material distribution mechanism 7, which is located between the first connecting plate 731 and the second pressing strip 723, can be clamped by moving the piston rod of the second vertical pressing cylinder 721 downward, so that the hot-melt braided sleeve located at the material distribution mechanism 7 is also clamped, making the laser cutting process more stable, or only using the pressing mechanism 5 to press the local hot-melt braided sleeve. After the cutting is completed, the first connecting plate 731 is driven downward by the second vertical pressing cylinder 721 to press the cut hot-melt braided sleeve located at the material distribution mechanism 7.

[0064] S6. The cut hot-melt braided sleeve is driven by the pulling cylinder 71 to move away from the roller conveying mechanism 3, so that the cut hot-melt braided sleeve is completely separated from the remaining uncut hot-melt braided sleeve and falls onto the blanking chute 81. Finally, the processed cut part is collected by the blanking collection box 82.

[0065] The cutting method of the hot-melt braided sleeve of the present invention controls the speed of the driving motor through a control panel, and displays the delivered length of the hot-melt braided sleeve in real time, and then uses a pressing mechanism to press the local section of the hot-melt braided sleeve delivered by the roller conveying mechanism from a circular ring shape to a flat shape, thereby preventing the hot-melt braided sleeve from moving during cutting. In addition, the laser cutting mechanism is used for cutting so that the fracture is fused and not scattered. Finally, the cut hot-melt braided sleeve is pushed upward by a second vertical pressing cylinder, and the cut hot-melt braided sleeve is pressed between the second pressing strip and the first connecting plate. Finally, the pulling cylinder drives the cut hot-melt braided sleeve to move to the side away from the roller conveying mechanism, so that the cut hot-melt braided sleeve is completely separated from the remaining hot-melt braided sleeve, eliminating the adhesion phenomenon after cutting, and ensuring the final product quality.

A hot melt braided sleeve cutting device according to claim 6, characterized in that: The connecting portion (73) includes a first connecting plate (731), a second connecting plate (732), a third connecting plate (733), a fourth connecting plate (734) and a fifth connecting plate (735) which are connected end to end in sequence, the second connecting plate (732) and the fourth connecting plate (734) are both vertically arranged, the first connecting plate (731), the third connecting plate (733) and the fifth connecting plate (735) are all horizontally arranged, the piston rod of the pulling cylinder (71) passes through the pulling cylinder seat (711) and is fixedly connected to the fourth connecting plate (711). 34), a space enclosed by the first connecting plate (731), the second connecting plate (732), the third connecting plate (733) and the fourth connecting plate (734) is provided with a second vertical pressing cylinder (721) which can move up and down, and the second vertical pressing cylinder (721) can drive the second cylinder connecting plate (722) and the second pressing strip (723) to move up and down along the second connecting plate (732), so that the cut hot-melt braided sleeve is pressed between the second pressing strip (723) and the first connecting plate (731).

8. A hot-melt braided sleeve cutting device according to claim 7, characterized in that: An anti-slip groove (7311) is provided above the first connecting plate (731) to prevent the cut hot-melt braided sleeve from sliding.

9. A method for cutting a hot melt braided sleeve, characterized in that: The following steps are involved: A plurality of hot-melt braided sleeves are transmitted to a material pressing mechanism (5) through a first guide adjustment mechanism (2), a roller transmission mechanism (3) and a second guide adjustment mechanism (4); The material pressing mechanism (5) presses a local section of the hot-melt braided sleeve at a cutting point close to the roller conveying mechanism (3) from a circular shape to a flat shape; Start the laser cutting mechanism (6) and adjust the focal length of the laser up and down, and then cut off the hot-melt braided sleeve adjacent to the flat shape; The cut hot-melt braided sleeve is pushed upward by the second vertical pressing cylinder (721), so that the cut hot-melt braided sleeve is pressed between the second pressing strip (723) and the first connecting plate (731); The cut hot-melt braided sleeve is driven by the pulling cylinder (71) to move away from the roller conveying mechanism (3), so that the cut hot-melt braided sleeve is completely separated from the remaining uncut hot-melt braided sleeve and falls onto the blanking slide (81), and finally the processed cut part is collected by the blanking collection box (82).
