Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, specifically a traction cutting device. Background Technology

[0002] Existing cutting machines are typically used for cutting tubular materials such as plastic hoses to a fixed length. Structurally, they mainly consist of two parts: a traction mechanism and a cutting mechanism. The cutting mechanism uses a single blade, which rotates under the action of a drive device and cuts the hose by cooperating with a die.

[0003] However, in practical applications, existing cutting machines for traction and cutting thin-walled hoses easily reveal many defects. Traditional two-roller structures are prone to problems such as hose deformation due to over-clamping or insufficient clamping force leading to inadequate friction and poor traction when adjusting clamping force. Furthermore, the lack of an effective guiding device causes the thin-walled hose to easily deviate or sag during traction, increasing operational difficulty and affecting product consistency. Single-blade vertical rotation cutting methods suffer from blade vibration, making it difficult to control the gap between the blade and the die. This results in rapid blade wear, incomplete cutting, or frequent friction between the blade and the die, thus affecting cutting quality, equipment lifespan, and production efficiency. Additionally, the overall structure occupies a large space and is inconvenient to operate. Utility Model Content

[0004] The purpose of this invention is to provide a traction-type cutting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a traction-type cutting device, comprising: a workbench, with a discharge port on one side and a control box mounted on the top; a support frame, mounted on the top of the workbench and directly above the discharge port, with a feed inlet on the side; mounting frames, two mounting frames respectively mounted on the top of the workbench and located on the side of the feed inlet; a roller cutter assembly, movably mounted on the support frame; a traction mechanism, disposed between the two mounting frames; a drive mechanism, installed inside the workbench and connected to the roller cutter assembly and the traction mechanism respectively; and a guide groove, adjustablely disposed at the ends of the two mounting frames by bolts, with a guide sleeve at each end, the guide sleeve penetrating the feed inlet and extending into the interior of the support frame, and a through hole at the bottom of the guide groove.

[0006] In one feasible embodiment, the hobbing cutter assembly includes: a rotating shaft rotatably mounted on the inner side of a support frame; a hobbing cutter fitted on the rotating shaft and capable of moving axially along the rotating shaft; and a fixed cutter disposed on the inner side of the support frame.

[0007] In one feasible implementation, the support frame is equipped with flip-up cover plates at both ends, and has notches on both sides that match the hob cutter shaft. The hob cutter shaft can be adapted to the notches under the limitation of the positioning block.

[0008] In one feasible embodiment, the traction mechanism includes: a lower conveying roller, which is rotatably disposed between two mounting frames; a limiting groove, wherein a plurality of limiting grooves are symmetrically arranged in pairs on the two mounting frames; a slider, wherein a plurality of sliders are movably disposed in pairs at the limiting grooves, wherein the two sliders in each pair are disposed opposite to each other and are fixedly connected by a connecting plate; an upper conveying roller, wherein a plurality of upper conveying rollers are rotatably disposed on the plurality of sliders; and an adjusting assembly, wherein the adjusting assembly is mounted on the plurality of sliders.

[0009] In one feasible implementation, the adjustment assembly includes: a fixing member, wherein a plurality of fixing members are respectively mounted on the mounting bracket in pairs by screws; a top plate, wherein a plurality of top plates are respectively disposed between two fixing members; and a threaded rod, wherein a plurality of threaded rods are respectively screwed to the middle part of the top plate and the bottom end is movably connected to the connecting plate, and the top end of the threaded rod is also provided with an adjustment handwheel.

[0010] In one feasible implementation, the driving mechanism includes: a first drive motor, which is mounted on the inner side of the workbench and connected to a rotating shaft via a belt pulley; a second drive motor, which is disposed on the inner side of the workbench; a first gear, wherein a plurality of first gears are respectively fixedly mounted on the pins of a plurality of the lower conveyor rollers, and one of the first gears is connected to the drive end of the second drive motor via a belt pulley; a connecting gear, wherein a plurality of connecting gears are respectively rotatably disposed on the wall of the mounting frame and mesh with the plurality of first gears; and a second gear, wherein a plurality of second gears are respectively fixedly mounted on the pins of a plurality of the upper conveyor rollers and mesh with the plurality of first gears.

[0011] Compared with existing technologies, the beneficial effects of this invention are as follows: This device, by adding a set of traction rollers to the traction section, effectively enhances the frictional force on the thin-walled hose, ensuring it receives sufficient power during traction without being squeezed or deformed. Combined with the guide grooves added between each set of traction rollers, it accurately guides the thin-walled hose, preventing sagging or deviation due to thin walls or gravity, ensuring the hose smoothly enters the cutting process, thereby significantly improving traction stability and product qualification rate. In the cutting stage, the original single blade is replaced with a multi-bladed roller cutter, employing horizontal cutting technology. This creates a small-angle inclined shearing state between the roller cutter and the fixed blade, effectively reducing friction and vibration during cutting, extending the service life of the roller cutter and fixed blade. Simultaneously, the multi-bladed structure allows for more cuts at the same rotational speed, significantly improving cutting efficiency and reducing the frequency of blade replacements. The compact design integrating the cutting machine and traction machine shortens the distance from traction to cutting, reducing interference and errors during transmission, making overall operation more stable and reliable, saving equipment space, and further improving operational convenience and production efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 8 This utility model provides a technical solution: a traction-type cutting device, including: a workbench 1, a support frame 4, a mounting frame 5, a roller cutter assembly, a traction mechanism, and a drive mechanism. The workbench 1 has a discharge port 2 on one side and a control box 3 mounted on its top. The support frame 4 is mounted on the top of the workbench 1, directly above the discharge port 2, and has a feed hole on its side. Two mounting frames 5 are respectively mounted on the top of the workbench 1, located on the side of the feed hole. The roller cutter assembly is movably mounted on the support frame 4. The traction mechanism is located between the two mounting frames 5. The drive mechanism is installed inside the workbench 1 and is connected to both the roller cutter assembly and the traction mechanism. A guide groove 16 is adjustablely mounted at the ends of the two mounting frames 5 via bolts, and a guide sleeve 17 is also provided at the end. The guide sleeve 17 passes through the feed hole and extends into the interior of the support frame 4, and a through hole is provided at the bottom of the guide groove 16.

[0023] It should be noted that the entire traction and cutting process is powered by a drive mechanism located inside the workbench 1 and connected to both the roller cutter assembly and the traction mechanism, enabling synchronous driving and coordinated operation of both. During cutting, the drive mechanism is activated, causing the traction mechanism and the roller cutter assembly to begin operation. The thin-walled hose is first pulled into the support frame 4 through the feed hole on the side of the support frame 4 by the traction mechanism. With the continuous cooperation of the traction mechanism, the thin-walled hose is moved continuously and stably towards the roller cutter assembly. The roller cutter assembly cuts the thin-walled hose, forming short granular structures. The cut thin-walled hose, now in granular form, is finally discharged from the discharge port 2 on one side of the workbench 1. The entire process is uniformly controlled and operated by a control box 3 installed at the top of the workbench 1. The control box 3's control of the first drive motor 21 and the second drive motor 22 is well-known to those skilled in the art and will not be described in detail here.

[0024] The hobbing cutter assembly includes: a rotating shaft 6, a hob 7, and a fixed cutter 8. The rotating shaft 6 is rotatably mounted on the inner side of the support frame 4; the hob 7 is mounted on the rotating shaft 6 and can move along the axial direction of the rotating shaft 6; the fixed cutter 8 is located on the inner side of the support frame 4.

[0025] It should be noted that when the rotating shaft 6 rotates under the action of the drive mechanism, the hob 7 mounted on the rotating shaft 6 rotates accordingly and forms a shearing engagement with the fixed blade 8, thereby cutting the material fed into the inner side of the support frame 4. The hob 7 can move axially along the rotating shaft 6, so that the hob 7 can be disengaged from the rotating shaft 6, which facilitates the disassembly, replacement or position adjustment of the hob 7 to adapt to the cutting requirements of materials of different sizes or specifications.

[0026] In some examples, the support frame 4 is further equipped with flip-up cover plates 9 at both ends, and notches 10 matching the cutter shaft of the hob 7 are provided on both sides. The cutter shaft of the hob 7 can be adapted to the notches 10 under the limitation of the positioning block 11.

[0027] It should be noted that, in use, the hob 7 cutter shaft is limited by the positioning block 11 and fits into the notch 10 of the cover plate 9. Under the action of the drive mechanism, the hob 7 achieves stable rotation. When it is necessary to disassemble or replace the hob 7, first flip the cover plate 9 to open it, releasing the positioning block 11 from limiting the hob 7 cutter shaft, allowing the hob 7 cutter shaft to disengage from or align with the notch 10, thereby enabling the disassembly or installation of the hob 7 cutter shaft. The flipping of the cover plate 9 and its engagement with the notch 10 facilitate the quick disassembly, assembly, and adjustment of the hob 7.

[0028] In some examples, the traction mechanism further includes: a lower conveyor roller 12, a limiting groove 13, a slider 14, an upper conveyor roller 15, a guide groove 16, and an adjustment assembly. The lower conveyor rollers 12 are rotatably disposed between two mounting frames 5. Several limiting grooves 13 are symmetrically arranged in pairs on the two mounting frames 5. Several sliders 14 are mounted in pairs on the several limiting grooves 13 and are movable in the vertical direction. The two sliders 14 in each pair are arranged opposite each other and are fixedly connected by a connecting plate. Several upper conveyor rollers 15 are rotatably disposed on the several sliders 14. The adjustment assembly is mounted on the several sliders 14.

[0029] It should be noted that the material enters between the lower conveyor roller 12 and the upper conveyor roller 15 under the guidance of the guide groove 16. The through hole opened in the guide groove 16 allows the lower conveyor roller 12 to pass through, so that the surfaces of the lower conveyor roller 12 and the upper conveyor roller 15 are in contact with the hose, forming friction on the hose, thereby achieving a traction effect. Driven by the drive mechanism, the lower conveyor roller 12 and the upper conveyor roller 15 pull the material towards the support frame 4 through friction. After the material is fed into the support frame 4 through the guide sleeve 17, the drive mechanism drives the rotating shaft 6 to rotate, so that the hob 7 and the fixed blade 8 mounted on the rotating shaft 6 form a shearing engagement to cut the material. The cut material is discharged from the discharge port 2 on one side of the workbench frame 1.

[0030] The adjustment component is installed on the slider 14. The height position of the slider 14 in the limiting groove 13 can be precisely adjusted by the adjustment component, thereby realizing the adjustment of the gap between the upper conveying roller 15, the lower conveying roller 12 and the guide sleeve 17, ensuring that the material moves into the support frame 4 in a controlled and stable manner during the traction process. It is also suitable for cutting hoses of different sizes, thus improving the applicability.

[0031] In some examples, the adjustment components further include: a fixing member 18, a top plate 19, and a threaded rod 20. Several fixing members 18 are set on the mounting bracket 5 in pairs by screws; several top plates 19 are respectively set between two fixing members 18; several threaded rods 20 are respectively screwed to the middle part of the top plate 19, and the bottom end is movably connected to the connecting plate. The top end of the threaded rod 20 is also provided with an adjustment handwheel.

[0032] It should be noted that during operation, several fasteners 18 are installed in pairs on the mounting bracket 5 with screws to support and fix the position of the top plate 19. The threaded rod 20 can rotate within the top plate 19 to achieve height adjustment. During operation, the adjusting handwheel at the top of the threaded rod 20 can be rotated to move the threaded rod 20 up and down, thereby causing the connecting plate to rise and fall accordingly. This allows for precise adjustment of the vertical height of the slider 14 and the upper conveyor roller 15, facilitating the adjustment of the conveyor roller gap according to the size requirements of different materials, ensuring that materials can be smoothly clamped and pulled.

[0033] In some examples, the drive mechanism further includes: a first drive motor 21, a second drive motor 22, a first gear 23, a connecting gear 24, and a second gear 25. The first drive motor 21 is mounted on the inner side of the workbench 1 and connected to the rotating shaft 6 via a belt pulley. The second drive motor 22 is located on the inner side of the workbench 1. Several first gears 23 are respectively fixedly mounted on the pins of several lower conveyor rollers 12, and one of the first gears 23 is connected to the drive end of the second drive motor 22 via a belt pulley. Several connecting gears 24 are rotatably mounted on the wall of the mounting frame 5 and mesh with several first gears 23. Several second gears 25 are respectively fixedly mounted on the pins of several upper conveyor rollers 15 and mesh with several first gears 23.

[0034] It should be noted that during operation, the first drive motor 21 is installed inside the workbench 1 and connected to the rotating shaft 6 via a belt and pulley, providing rotational power to the rotating shaft 6. The second drive motor 22 is also located inside the workbench 1 and provides power to the lower conveyor roller 12 and the upper conveyor roller 15. One of the first gears 23 is connected to the drive end of the second drive motor 22 via a belt and pulley, transmitting power. The connecting gear 24 meshes with several of the first gears 23 to further distribute and transmit power. The second gear 25 meshes with several of the first gears 23, thereby achieving synchronous rotation of the lower conveyor roller 12 and the upper drive roller, ensuring that the material is stably and uniformly clamped and conveyed.
