Description

Technical Field

[0001] This utility model relates to the field of sleeve preparation technology, and in particular to a self-winding sleeve shaping machine and extrusion equipment. Background Technology

[0002] Rigid self-winding sleeves are a common type of black or gray wire harness outer casing, often used for bundling wire harnesses, protecting automotive wire harnesses, or guiding wire harnesses. Common materials include PVC, PP, and PE. The structure of rigid self-winding sleeves is very simple; during processing, they are formed into an open, self-winding state, making them easy to insert into automotive wire harnesses. They are widely used for wear-resistant protection of automotive wire harnesses.

[0003] The common preparation method involves continuously forming the above-mentioned material melt through a screw extruder using a die of a specific shape, resulting in a continuous product with a constant cross-sectional shape. The drawback of this method is that different sizes and overlap ratios of self-winding tubes require the design of corresponding dies of specific shapes. These dies are often complex curved surfaces, making processing difficult and costly. Utility Model Content

[0035] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0036] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0037] Please combine them together Figures 1 to 3 The self-winding sleeve shaping machine provided by this utility model will now be described. The self-winding sleeve shaping machine is used in extrusion equipment.

[0038] The self-winding sleeve includes: a frame 1, a slitting assembly 2, a pressure roller assembly 3, and a traction assembly 4. The slitting assembly 2 includes a support rod 21, a cutter bar 22, and a cutting blade 23. The support rod 21 is fixed to the frame 1, the cutter bar 22 is fixed to the support rod 21 and is used for the sleeve to pass through, and the cutting blade 23 is fixed to the support rod 21 and is used to cut the sleeve to form a slit and then self-wind. The pressure roller assembly 3 is fixed to the frame 1 and is used to press the different overlap rates of the self-winding sleeve. The traction assembly 4 is fixed to the frame 1 and is used to traction the sleeve.

[0039] Understandably, the support rod 21 of this self-winding sleeve forming machine is fixed to the frame 1, the cutter bar 22 is fixed to the support rod 21 and used for the sleeve to pass through, the cutting blade 23 is fixed to the support rod 21 and used to cut the sleeve to form a slit and then self-wind, the pressure roller assembly 3 is fixed to the frame 1 and used to press the sleeve with different overlap rates after self-winding, and the traction assembly 4 is fixed to the frame 1 and used to traction the sleeve. The traction assembly 4 pulls the sleeve to move. After the sleeve passes through the cutter bar 22, it is cut by the cutting blade 23, so that the sleeve forms a slit along the axial direction and then self-winds. Under the pressure of the pressure roller assembly 3, the self-winding sleeve can form sleeves with different overlap rates. Compared with the specific shape die in the prior art, it does not need to be changed according to the size and overlap rate of the sleeve, which is convenient for processing and reduces production costs.

[0040] Furthermore, the self-winding sleeve shaping machine is compatible with common pipe extrusion equipment. After automatically splitting the extruded sleeve into an opening, the self-winding sleeve has a significantly improved processing speed compared to the self-winding sleeve produced by a specific shaped die in the existing technology. Taking the production line of the same model and screw size of the extruder to produce the same self-winding shape pipe with the same diameter and wall thickness as an example, the production capacity of the shaping process using a specific shaped die is generally 200 to 300 meters per hour. After the extrusion equipment extrudes the same size sleeve and shapes it, the production capacity using this self-winding sleeve shaping machine can reach 400 to 500 meters per hour, which is a significant increase in production capacity.

[0041] It should be noted that after the extrusion equipment extrudes the sleeve, the sleeve passes through the cutter bar 22, and the cutting blade 23 can cut the sleeve, so that the sleeve forms a slit along the axial direction and then self-rolls. The self-rolled sleeve is then placed on the pressure roller assembly 3 for pressing to adjust the overlap rate of the self-rolled sleeve. The self-rolled sleeve is then pulled by the traction assembly 4, so that the sleeve can be continuously transported to the next process for cutting.

[0042] In this embodiment, the cutting blade 23 is disposed on one side relative to the sleeve conveying direction and located below the cutter bar 22. This allows the cutting blade 23 to cut the sleeve and create a slit as it passes through the cutter bar 22.

[0043] Furthermore, the cutter shank 22 is detachably connected to the support rod 21, allowing the cutter shank 22 to be replaced to match sleeves with larger or smaller diameters. For sleeves with only a small diameter difference, the cutter shank 22 may not need to be replaced. The cutting disc 23 is detachably connected to the support rod 21. The cutting disc 23 is replaceable; after a period of use, it will wear out, requiring replacement to ensure it can smoothly cut kerfs.

[0044] In one embodiment, such as Figure 1As shown, the pressure roller assembly 3 includes a mounting platform 31, an adjusting member 32, a first pressure roller group 33, and a second pressure roller group 34. The first pressure roller group 33 is slidably connected to the mounting platform 31. The adjusting member 32 is threadedly connected to the mounting platform 31 and abuts against the first pressure roller group 33 to adjust the gap between the first pressure roller group 33 and the second pressure roller group 34. Specifically, the adjusting member 32 can be a bolt. The adjusting member 32 is threadedly connected to the mounting platform 31. Rotating the adjusting member 32 allows it to move relative to the mounting platform 31, enabling it to abut against the first pressure roller group 33. Since the first pressure roller group 33 is slidably connected to the mounting platform 31, the adjusting member 32 can move the first pressure roller group 33 closer to or further away from the second pressure roller group 34 to adjust the gap between the first pressure roller group 33 and the second pressure roller group 34, thereby adjusting the overlap rate of the self-winding sleeve.

[0045] Of course, in other embodiments, the first pressure roller group 33 and the second pressure roller group 34 are both slidably connected to the mounting platform 31, and the adjusting member 32 is rotatably connected to the mounting platform 31. The two sections of threads with opposite directions on the adjusting member 32 are respectively threaded to the first pressure roller group 33 and the second pressure roller group 34. Rotating the adjusting member 32 causes the two sections of threads with opposite directions to move the first pressure roller group 33 and the second pressure roller group 34 closer together or further apart, thereby adjusting the gap between the first pressure roller group 33 and the second pressure roller group 34, and thus adjusting the overlap rate of the self-winding sleeve.

[0046] In one embodiment, such as Figure 3 As shown, the traction assembly 4 includes a support frame 41, a first conveying module 42, and a second conveying module 43. Both the first and second conveying modules 42 and 43 are mounted on the support frame 41, and are spaced apart to form a conveying space 100. The first and second conveying modules 42 and 43 drive the sleeve to move within the conveying space 100. Specifically, the self-wound sleeve, within the conveying space 100, is continuously conveyed by the friction of the first and second conveying modules 42 and 43, allowing the sleeve to be continuously slit and transported to the next process for cutting.

[0047] In this embodiment, the traction assembly 4 further includes an adjustment module 44, which is mounted on the support frame 41 and used to adjust the interval between the first conveying module 42 and the second conveying module 43 to form conveying spaces 100 of different sizes. This allows for the conveying of sleeves of different diameters, improving applicability.

[0048] Furthermore, the adjustment module 44 includes a rotating component 441 and a lead screw 442. The rotating component 441 is fixed to the lead screw 442, which is threadedly connected to the support frame 41 and rotatably connected to the first conveying module 42. By rotating the rotating component 441, the rotating component 441 drives the lead screw 442 to rotate, and the lead screw 442 moves relative to the support frame 41. The lead screw 442 causes the first conveying module 42 to move closer to or further away from the second conveying module 43, thereby adjusting the interval between the first conveying module 42 and the second conveying module 43 to form conveying spaces 100 of different sizes.

[0049] Specifically, both the first conveying module 42 and the second conveying module 43 include a conveying frame, a drive motor, a first pulley, a second pulley, and a belt. The first and second pulleys are rotatably connected to the conveying frame and located at opposite ends of the frame. The drive motor is fixed to the conveying frame and is drively connected to one of the first and second pulleys. The belt wraps around both pulleys. In implementation, the drive motor drives the first pulley to rotate, which in turn moves the belt, causing the second pulley to rotate, thus enabling the belt to convey the sleeve.

[0050] In one embodiment, such as Figure 1 and Figure 3 As shown, the self-winding sleeve also includes a guide member 5, which is fixed to the frame 1 and located between the pressure roller assembly 3 and the traction assembly 4. The guide member 5 has a guide hole 51 for the sleeve to pass through and for guidance. By providing the guide member 5, the sleeve can pass through the guide hole 51 and enter the traction assembly 4, thereby guiding the sleeve.

[0051] This utility model also provides an extrusion device, which includes the self-winding sleeve shaping machine of any of the above embodiments.

[0052] It is understood that the extrusion equipment of this utility model uses the aforementioned self-winding sleeve forming machine, in which the support rod 21 of the self-winding sleeve forming machine is fixed to the frame 1, the cutter bar 22 is fixed to the support rod 21 and used for the sleeve to pass through, the cutting blade 23 is fixed to the support rod 21 and used for cutting the sleeve to form a slit and then self-winding, the pressure roller assembly 3 is fixed to the frame 1 and used for pressing the sleeve with different overlap rates after self-winding, and the traction assembly 4 is fixed to the frame 1 and used for traction of the sleeve. The traction assembly 4 pulls the sleeve to move, and after the sleeve passes through the cutter bar 22, it is cut by the cutting blade 23, so that the sleeve forms a slit along the axial direction and then self-winds. Under the pressure of the pressure roller assembly 3, the self-winding sleeve can form sleeves with different overlap rates. Compared with the specific shape die in the prior art, it is not necessary to change according to the size and overlap rate of the sleeve, which is convenient for processing and reduces production costs.

[0053] Furthermore, the self-winding sleeve shaping machine is compatible with common pipe extrusion equipment. After automatically splitting the extruded sleeve into an opening, the self-winding sleeve has a significantly improved processing speed compared to the self-winding sleeve produced by a specific shaped die in the existing technology. Taking the production line of the same model and screw size of the extruder to produce the same self-winding shape pipe with the same diameter and wall thickness as an example, the production capacity of the shaping process using a specific shaped die is generally 200 to 300 meters per hour. After the extrusion equipment extrudes the same size sleeve and shapes it, the production capacity using this self-winding sleeve shaping machine can reach 400 to 500 meters per hour, which is a significant increase in production capacity.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
