Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of oil drilling hose cutting equipment, specifically, to a cutting device for oil drilling hose production. Background Technology

[0002] In the field of oil drilling hose production, the continuity of hose cutting process and the efficiency of finished product handling directly affect the overall efficiency of the production line. However, traditional cutting equipment generally suffers from poor continuity and finished product accumulation, resulting in low production efficiency and high manual handling costs, making it difficult to meet the needs of modern mass production.

[0003] Existing cutting equipment suffers from significant structural defects: Firstly, the cutting mechanism operates intermittently, lacking a dynamic cutting design synchronized with hose conveying. When the hose moves continuously via the conveyor, the single-blade cutting head of traditional equipment requires frequent start-stop adjustments, and cutting positioning relies on mechanical limits, resulting in a mismatch between cutting rhythm and conveying speed. For example, when processing large-diameter hoses, the equipment must stop and wait for the hose to arrive, with a single cutting interval of up to 15 seconds, severely impacting production continuity. Secondly, the finished product collection system is poorly designed, often consisting of open-bottom receiving troughs lacking automatic sorting and sorting mechanisms. Cut hoses fall directly into the trough, deforming due to their own weight, and hoses of different lengths are mixed together, requiring manual sorting, which is time-consuming and labor-intensive. Furthermore, the cutting and collection processes of traditional equipment are independent, lacking a linkage adjustment mechanism. When changing hose specifications, the machine must be stopped to manually adjust the cutting length parameters and the position of the receiving trough baffle, resulting in low changeover efficiency.

[0004] As oil drilling and production operations become more large-scale and standardized, the demand for "continuous production and automated processing" of hose cutting is becoming increasingly urgent. For example, shale gas extraction hoses need to be continuously cut to a fixed length, and the finished products need to be neatly stacked. Traditional cutting equipment, due to its "outdated cutting mechanism and rudimentary collection system," can no longer meet the process requirements of "efficient cutting and convenient processing." There is an urgent need to develop new equipment with dynamic continuous cutting and automatic processing functions to solve the industry problems of "poor continuity and difficulty in sorting stacked products," and promote the intelligent and intensive upgrading of oil drilling hose production. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a cutting device for the production of oil drilling hoses, which solves the problem that the continuity of the hose cutting process and the efficiency of finished product handling directly affect the overall efficiency of the production line in the prior art. However, traditional cutting equipment generally suffers from poor continuity and finished product accumulation, resulting in low production efficiency and high manual handling costs.

[0006] According to one aspect, at least one embodiment of this disclosure provides a cutting device for producing oil drilling hoses, comprising:

[0007] The equipment rack and the drive motor are provided, with the drive motor located on one side of the upper equipment rack.

[0008] A cutting assembly is provided inside the equipment frame;

[0009] A set of outer frames and a straightening guide assembly, wherein the outer frames are fixed to the side end face of the equipment frame, and the straightening guide assembly is disposed between the outer frames;

[0010] The propulsion cutting assembly includes a pair of rotating shafts, each rotatably connected to the side surface of the equipment frame. Each rotating shaft has a transmission gear at one end, and the transmission gears mesh with each other. The drive motor is connected to one of the rotating shafts, and a drive block is provided at one end of the rotating shaft. A propulsion wheel is fitted onto the drive block.

[0011] As a further technical solution, a mounting groove is provided on the side surface of the equipment frame, a connecting frame is inserted into the mounting groove, the connecting frame is fixedly connected to the mounting groove by bolts, a driven shaft is rotatably connected in the connecting frame, and one end of the driven shaft is connected to the propulsion wheel.

[0012] As a further technical solution, a rectangular plate is provided on one side of the equipment frame, a positioning groove is provided in the rectangular plate, and a through hole is provided on the side surface of the rectangular plate. A telescopic cylinder is provided on one side surface of the equipment frame, and a cutter is provided at the output end of the telescopic cylinder. The cutter slides against the inner wall of the positioning groove.

[0013] As a further technical solution, the straightening guide component includes a guide tube, which is fixed between the outer frames. Several movable columns are movably connected inside the outer frames, and the lower end of each movable column is connected to a crossbar.

[0014] As a further technical solution, each of the movable columns is fitted with a spring clip, and several guide wheels are rotatably connected between the crossbeams, with the guide wheels and the guide tube located in the same straight line position.

[0015] As a further technical solution, a discharge assembly is also included. The discharge assembly is disposed inside the equipment frame. The discharge assembly includes a pair of second cylinders. The output end of the second cylinder is connected to a pusher plate. A discharge port is opened on one side surface of the equipment frame.

[0016] As a further technical solution, both the propulsion wheel and the guide wheel have arc-shaped concave structural surfaces.

[0017] As a further technical solution, the connection between the driving block and the driven shaft is a polygonal structure.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] 1. In this disclosure, the propulsion cutting assembly drives the rotating shaft through the drive motor, and the two propulsion wheels rotate synchronously through the transmission gear to stably propel the hose. The connecting frame can be adjusted in position within the mounting slot to adapt to hoses of different specifications. The positioning slot of the rectangular plate provides guidance for the cutter. The telescopic cylinder pushes the cutter to accurately cut the hose, solving the problem of poor continuity in intermittent cutting of traditional equipment, realizing continuous hose propulsion and rapid cutting, improving cutting efficiency and accuracy, and ensuring that the cutting rhythm matches the conveying speed.

[0020] 2. In this disclosure, the inlet tube of the straightening inlet assembly provides a guide channel for the hose. The spring clip on the movable column causes the crossbeam to drive the inlet wheel to elastically fit the hose. When the hose moves forward, the inlet wheel rolls to smooth out the bends and wrinkles, so that the hose enters the cutting equipment in a straight line. This avoids the cutting position deviation caused by the hose not being straight, provides a regular cutting object for the cutting assembly, improves the cutting quality, and reduces equipment jamming caused by the hose bending.

[0021] 3. In this disclosure, the second cylinder of the discharge component drives the pusher plate to push the hose out of the discharge port after the hose is cut, so as to avoid the cut hose from accumulating in the equipment, prevent the hose from being squeezed and deformed due to accumulation, and allow hoses of different specifications to be discharged in an orderly manner, which is convenient for external collection and sorting, reduces the amount of manual sorting work, and is linked with the push cutting component to ensure smooth internal flow of the equipment, improve the overall operating efficiency of the cutting equipment, and realize the automated connection between cutting and discharge.

[0033] like Figures 1-3 As shown, it illustrates a cutting device for producing oil drilling hoses according to an embodiment of this disclosure, comprising:

[0034] The equipment frame 1 and the drive motor 2 are arranged on one side of the upper equipment frame 1;

[0035] A cutting assembly 4 is propelled and disposed inside the equipment frame 1;

[0036] A pair of outer frames 3 and a straightening guide component 5 are provided. The outer frames 3 are fixed to the side end face of the equipment frame 1, and the straightening guide component 5 is arranged between the outer frames 3.

[0037] The propulsion cutting assembly 4 includes a pair of rotating shafts 4-1, each rotatably connected to the side surface of the equipment frame 1. Each rotating shaft 4-1 has a transmission gear 4-2 at one end, and the transmission gears 4-2 mesh with each other. The drive motor 2 is linearly connected to one of the rotating shafts 4-1. A drive block 4-3 is provided at one end of each rotating shaft 4-1, and a propulsion wheel 4-4 is fitted onto the drive block 4-3. A mounting groove 4-5 is provided on the side surface of the equipment frame 1, and a connecting frame 4-6 is inserted into the mounting groove 4-5. -6 is fixedly connected to the mounting groove 4-5 by bolts. A driven shaft 4-7 is rotatably connected inside the connecting frame 4-6. One end of the driven shaft 4-7 is connected to the push wheel 4-4. A rectangular plate 4-8 is provided on one side of the equipment frame 1. A positioning groove 4-9 is opened in the rectangular plate 4-8. A through hole 4-10 is opened on the side surface of the rectangular plate 4-8. A telescopic cylinder 4-11 is provided on one side surface of the equipment frame 1. A cutter 4-12 is provided at the output end of the telescopic cylinder 4-11. The cutter 4-12 slides against the inner wall of the positioning groove 4-9.

[0038] In some examples, a propulsion cutting assembly 4 is designed to achieve precise positioning and rapid cutting of the hose. This assembly uses a pair of rotating shafts 4-1 rotatably connected within the side surface of the equipment frame 1 as its power transmission core. A drive motor 2 is connected to one of the rotating shafts 4-1, and through the meshing of transmission gears 4-2, drives both rotating shafts 4-1 to rotate synchronously. A drive block 4-3 at one end of each rotating shaft 4-1 is fitted with a propulsion wheel 4-4. When the rotating shaft 4-1 rotates, the propulsion wheel 4-4 rotates accordingly, pushing the hose forward. A connecting bracket 4-6 is inserted into a mounting groove 4-5 on the side surface of the equipment frame 1, and its position can be adjusted by bolts. A driven shaft 4-7 within the connecting bracket 4-6 stably transmits power to the propulsion wheel 4-4.

[0039] A rectangular plate 4-8 on one side of the equipment frame 1 has a positioning groove 4-9 and a through hole 4-10. The positioning groove 4-9 provides a guide path for the cutter 4-12. When the hose is pushed to the designated position, the cutter 4-12 at the output end of the telescopic cylinder 4-11 slides along the inner wall of the positioning groove 4-9, passes through the through hole 4-10, and quickly cuts the hose. The synchronous transmission of the transmission gear 4-2 ensures that the hose is pushed forward at a uniform speed. The adjustable design of the connecting frame 4-6 adapts to hoses of different specifications. The cooperation between the positioning groove 4-9 and the cutter 4-12 achieves precise cutting position positioning. The push-cutting assembly 4 can complete the push-forward and cutting of the hose in a short time, ensuring cutting efficiency and cutting accuracy.

[0040] like Figures 1-3 As shown, this embodiment proposes that the straight inlet component 5 includes an inlet tube 5-1, which is fixed between the outer frames 3. Several movable columns 5-2 are movably connected inside the outer frames 3. The lower end of each movable column 5-2 is connected to a cross frame 5-3. Each movable column 5-2 is fitted with a spring clip 5-4. Several inlet wheels 5-5 are rotatably connected between the cross frames 5-3. The inlet wheels 5-5 and the inlet tube 5-1 are located in the same straight line position.

[0041] In some examples, a straightening guide assembly 5 is designed to straighten the hose for subsequent cutting. This assembly uses a guide tube 5-1 fixed between the outer frames 3 as a reference channel. Several movable columns 5-2, movably mounted inside the outer frames 3, are connected at their lower ends to a crossbeam 5-3. Spring clips 5-4 mounted on the movable columns 5-2 provide elastic support, allowing the crossbeam 5-3 to float up and down within a certain range. Guide wheels 5-5, rotatably connected between the crossbeams 5-3, are located in the same straight line as the guide tube 5-1. When the hose passes through the guide tube 5-1, the guide wheels 5-5 contact the hose from both sides. The elasticity of the spring clips 5-4 ensures that the guide wheels 5-5 always remain in contact with the hose surface. During the hose's advance, the guide wheels 5-5 smooth out any bends or wrinkles on the hose surface through rolling friction, ensuring the hose enters the cutting equipment in a straight state. Guided by the inlet tube 5-1, straightened by the rolling of the inlet wheel 5-5, and adjusted by the elasticity of the spring clip 5-4, the straightening inlet assembly 5 effectively straightens the hose, providing a regular cutting target for the propulsion cutting assembly 4 and improving the cutting quality.

[0042] like Figures 1-3 As shown, this embodiment also includes a discharge component 6, which is disposed inside the equipment frame 1. The discharge component 6 includes a pair of second cylinders 6-1, the output end of which is connected to a pusher plate 6-2. A discharge port 6-3 is provided on one side surface of the equipment frame 1.

[0043] In some examples, a discharge assembly 6 is designed to prevent the cut hose from accumulating inside the equipment. This assembly is powered by a pair of second cylinders 6-1 located inside the equipment frame 1. After the cutting assembly 4 completes the hose cutting process, the second cylinders 6-1 are activated, and the pusher plate 6-2 at its output end quickly extends along the guide structure inside the equipment frame 1. The width of the pusher plate 6-2 is adapted to the internal space of the equipment frame 1, covering the area where the hose is located, and pushing the cut hose as a whole towards the discharge port 6-3 on one side of the equipment frame 1. As the piston rod of the second cylinder 6-1 is fully extended, the hose is smoothly pushed out of the discharge port 6-3 and falls into the external collection device. After the hose is pushed out, the second cylinder 6-1 retracts, and the pusher plate 6-2 returns to its original position, waiting for the next push. Through the reciprocating extension and retraction of the second cylinder 6-1 and the coordinated action of the pusher plate 6-2, the discharge component 6 realizes the automatic external push of the cut hose, ensuring that the internal working space of the equipment is always unobstructed, effectively avoiding the accumulation of hoses that would interfere with subsequent cutting processes, and improving the overall operating efficiency of the cutting equipment.

[0044] For example, such as Figure 1 As shown, the surfaces of the propulsion wheel 4-4 and the guide wheel 5-5 are both arc-shaped concave structures.

[0045] In some examples, delivery is achieved by using an arc-shaped concave structure to tighten the hose, preventing the hose from being excessively squeezed and deformed.

[0046] For example, such as Figure 3 As shown, the connection between the driving block 4-3 and the driven shaft 4-7 is a polygonal structure.

[0047] In some examples, a polygonal structure can be used to achieve a transmission effect and prevent slippage during transmission.

[0048] In actual use: the equipment frame 1 is fixed, the drive motor 2 is installed on one side of the equipment frame 1, the rotating shaft 4-1 of the push cutting assembly 4 is rotatably connected to the side surface of the equipment frame 1, the transmission gear 4-2 meshes, the drive motor 2 is connected to one of the rotating shafts 4-1, the drive block 4-3 and the push wheel 4-4 are installed at one end of the rotating shaft 4-1, the connecting bracket 4-6 is inserted into the mounting groove 4-5 and fixed with bolts, the driven shaft 4-7 is connected to the push wheel 4-4, the rectangular plate 4-8 is fixed inside the equipment frame 1, the positioning groove 4-9 and the through hole 4-10 are opened on the rectangular plate 4-8, the telescopic cylinder 4-11 is installed on one side of the equipment frame 1 and the output end is connected to the cutter 4-12, the outer frame 3 is fixed to the side end face of the equipment frame 1, and the straight guide assembly 5 is... The inlet pipe 5-1 is fixed in the outer frame 3. The movable column 5-2 is movably fitted inside the outer frame 3 and its lower end is connected to the cross frame 5-3. The spring clip 5-4 is fitted on the movable column 5-2. The inlet wheel 5-5 is rotatably connected in the cross frame 5-3. The second cylinder 6-1 of the discharge assembly 6 is installed inside the equipment frame 1 and its output end is connected to the push plate 6-2. The discharge port 6-3 is opened on one side of the equipment frame 1. When in use, the hose is straight inlet through the inlet pipe 5-1 and the inlet wheel 5-5. The drive motor 2 drives the push wheel 4-4 to rotate and push the hose through the transmission gear 4-2. After reaching the designated position, the telescopic cylinder 4-11 pushes the cutter 4-12 to cut the hose. The second cylinder 6-1 drives the push plate 6-2 to push the cut hose out from the discharge port 6-3.
