Description

Technical Field

[0001] This invention belongs to the field of rubber hydraulic hose assembly processing technology, and particularly relates to a cutting device for processing rubber hydraulic hose assemblies. Background Technology

[0002] In modern industrial production, rubber hydraulic hoses are widely used in various hydraulic systems to transport hydraulic fluids. Cutting is a crucial step in the processing of rubber hydraulic hoses, as its quality directly affects the hose's service life and sealing performance. However, existing rubber hydraulic hose cutting devices have the following technical problems:

[0003] 1. Poor applicability: Existing cutting devices usually require a conveying and guiding device before cutting. However, existing conveying and guiding devices are usually only for rubber hydraulic hoses of fixed size. For hoses of different sizes, existing cutting devices often need to frequently adjust the positioning device, which is complicated and inefficient.

[0004] Second, low safety: When cutting rubber hydraulic hoses, a large amount of harmful fumes are generated due to the thermal decomposition of rubber materials; most existing cutting devices are not equipped with effective fume purification systems, or the purification systems are not designed reasonably.

[0005] 3. Low integration: Existing cutting devices usually separate functions such as material conveying, positioning, cutting, and fume treatment into different devices or modules, lacking integrated design, which leads to complicated operation and high maintenance costs;

[0006] To address the shortcomings of existing technologies, this invention provides a cutting device for processing rubber hydraulic hose assemblies, aiming to solve the aforementioned problems. Summary of the Invention

[0012] A cutting mechanism, which is detachably connected to the bottom of the top plate;

[0013] An auxiliary positioning mechanism, which is connected to the cutting mechanism, is used to assist in positioning the rubber hydraulic hose before cutting.

[0014] The system also includes a smoke purification mechanism, which is connected to the auxiliary positioning mechanism and is used to purify the smoke generated after cutting.

[0015] Preferably, the auxiliary positioning mechanism includes a positioning tube, a connecting column is connected to the side of the positioning tube, a threaded groove is provided on the top of the connecting column, a fine-tuning screw is internally threaded in the threaded groove, and a fine-tuning turntable is provided on the top of the fine-tuning screw.

Therefore, the positioning tube not only plays a positioning role but also plays a significant role in smoke discharge. This design allows for a larger suction area when smoke is inhaled, greatly reducing the diffusion of smoke, further improving the safety of the device, and also further improving the integration of the device.

[0048] A conveying and positioning mechanism 1, comprising a pair of conveying components 11; the pair of conveying components 11 are respectively mounted on a top plate 116 and a bottom plate 115 via multiple support frames 114.

[0049] Among them, a pair of conveying components 11 includes a pair of conveyor belts 111 symmetrically distributed vertically, and the pair of conveyor belts 111 drives the rubber hydraulic hose 6 through a transmission component; a second conveyor belt 12 is connected to the outside of the pair of conveyor belts 111, and the second conveyor belt 12 has multiple positioning grooves 121 of different sizes.

[0050] Cutting mechanism 2, which is detachably connected to the bottom of the top plate 116;

[0051] Auxiliary positioning mechanism 3 is connected to the cutting mechanism 2 and is used to assist in positioning the rubber hydraulic hose 6 before cutting.

[0052] And a smoke purification mechanism 4, which is connected to the auxiliary positioning mechanism 3, for purifying the smoke generated after cutting.

[0053] In this embodiment, the present invention designs a conveying and positioning mechanism 1. A pair of conveyor belts 111 drive the rubber hydraulic hose 6 through a transmission component. The conveyor belt 12 connected to the conveyor belt 111 has multiple positioning grooves 121 of different sizes, which can adapt to rubber hydraulic hoses 6 of different sizes. There is no need to frequently adjust the positioning device. At the same time, the conveying and positioning mechanism 1 enables the rubber hydraulic hose 6 to be positioned during the transmission process. No additional positioning mechanism is needed before cutting, which improves the integration of the device.

[0054] Example 2

[0055] Based on Example 1, and referring to Figure 1 , Figure 2 , Figure 6 and Figure 7 This embodiment also includes the following design.

[0056] Specifically, the auxiliary positioning mechanism 3 includes a positioning tube 31, a connecting post 32 connected to the side of the positioning tube 31, a threaded groove 321 on the top of the connecting post 32, a fine-tuning screw 34 internally threaded into the threaded groove 321, and a fine-tuning turntable 35 on the top of the fine-tuning screw 34.

[0057] Specifically, the smoke purification mechanism 4 includes a smoke guide pipe 41 that communicates with the positioning pipe 31. One end of the smoke guide pipe 41 is connected to a smoke purifier 42, which is mounted on the base plate 115.

[0058] In order to accommodate rubber hydraulic hoses 6 of different sizes and flexibly adjust the position of the cutting mechanism 2, in this embodiment, the top plate 116 is provided with multiple sets of positioning holes 117, and the inner side of the top plate 116 is also provided with a sliding groove 116a, and the positioning holes 117 are located above the sliding groove 116a.

[0059] Specifically, the cutting structure includes a Z-shaped mounting bracket 21, a cylinder 22, and a cutting motor 26; wherein,

[0060] The top of the Z-shaped mounting bracket 21 is slidably connected to the groove 116a, and is threaded into the threaded groove 211 on the top of the Z-shaped mounting bracket 21 after passing through the positioning hole 117 with the positioning screw 27; the bottom of the Z-shaped mounting bracket 21 has a threaded hole 213, and the fine-tuning screw 34 is threaded into the threaded hole 213; this design is used to finely adjust the height of the positioning tube 31 according to the size of the rubber hydraulic hose 6, so that the bottom of the rubber hydraulic hose 6 is close to the inner bottom of the positioning tube 31, but not completely fitted, thereby making the offset smaller and the accuracy higher during cutting.

[0061] The cylinder 22 is installed on the top inner side of the zigzag mounting bracket 21, and the output end of the cylinder 22 is connected to the cutting bracket 23. The cutting bracket 23 is provided with a cutting blade 24 via a rotating shaft 25.

[0062] The cutting motor 26 is located on the outside of the cutting frame 23, and the motor shaft of the cutting motor 26 is connected to one end of the rotating shaft 25.

[0063] It should be noted that, in order to make the positioning tube 31 move synchronously with the cutting mechanism 2 and achieve precise positioning, the central axis of the positioning tube 31 and the center of the cutting blade 24 are on the same straight line.

[0064] To prevent the positioning tube 31 from shifting left or right during height fine-tuning, in this embodiment, the auxiliary positioning mechanism 3 further includes a limiting frame 33. The bottom of the limiting frame 33 is fixedly connected to the connecting column 32, and its top is movably connected to the sliding hole 212 opened at the bottom of the Z-shaped mounting bracket 21.

[0065] Specifically and as is well known, the transmission assembly designed in this embodiment includes two sets of conveying gears 112 and a pair of motors 113; wherein,

[0066] The two sets of conveying gears 112 respectively mesh with the inner sides of a pair of conveyor belts 111. Both sets of conveying gears 112 are provided with axles. A pair of motors 113 are mounted on the support frame 114, and the motor shafts of the pair of motors 113 are respectively connected to the upper and lower axles. That is, there are a total of two motors, which act on the pair of symmetrically positioned conveyor belts.

[0067] In order to achieve automated control of the cutting process and improve cutting efficiency and quality, in this embodiment, the cutting device further includes a plurality of sensors 5, each of which is located on the inner side of the top plate 116 and is electrically connected to the cylinder 22 and the cutting motor 26.

[0068] In order to prevent the smoke from drifting back, in this embodiment, the smoke guide pipe 41 is also provided with a one-way valve 43.

[0069] In order to ensure that the smoke generated during cutting can be smoothly drawn into the smoke purifier 42, in this embodiment, the inner diameter of the positioning tube 31 is larger than the inner diameter of the smoke guide tube 41. This design allows for a larger suction area when the smoke is drawn in, which reduces the diffusion of the smoke to a greater extent and further improves the safety of the device.

[0070] Working principle:

[0071] Before cutting, according to the size of the rubber hydraulic hose 6 to be cut, place it into the corresponding placement groove of the conveyor belt 12, adjust the cutting position of the cutting mechanism 2, and fine-tune the positioning tube 31 by the fine-tuning turntable 35.

[0072] During cutting, motor 113, cylinder 22 and cutting motor 26 are started. Motor 113 transports and positions the rubber hydraulic hose 6. When it is transported to the set position, sensor 5 transmits its signal to the control system of the device. The control system controls cylinder 22 and cutting motor 26 to work through electrical signals. At the same time, the smoke generated after cutting is sequentially drawn into smoke purifier 42 through positioning tube 31 and smoke guide tube 41 to achieve safe operation.

[0073] In summary, by integrating functions such as conveying and positioning, cutting, auxiliary positioning, and fume purification, this invention achieves efficient and precise cutting of the rubber hydraulic hose 6, while improving the applicability, safety, and automation of the equipment, effectively solving the problems existing in the prior art.

[0074] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
