Description

Technical Field

[0001] The utility model relates to the field of multimedia, in particular to a cutting device for producing PE rubber hoses. Background Art

[0002] PE pipes include medium-density polyethylene pipes and high-density polyethylene pipes. According to the wall thickness, they are divided into SDR11 and SDR17.6 series. The former is suitable for conveying gaseous artificial gas, natural gas, and liquefied petroleum gas, while the latter is mainly used for conveying natural gas. Compared with steel pipes, the construction process is simpler and has a certain degree of flexibility. More importantly, it does not require anti-corrosion treatment, which will save a lot of processes. The disadvantage is that the mechanical properties are not as good as steel pipes. During construction, special attention should be paid to the safe spacing of thermal heating, and it cannot be exposed to the air and sunlight. It is sensitive to chemicals to prevent damage caused by leakage of sewage pipes.

[0003] PE hose production process often needs to be cut, but some existing PE hose production and processing cutting devices, such as the application number: CN201921823080.5, a PE hose production and processing cutting device, includes a workbench, a support frame, a movable seat, and a fixed block. The support frame is fixedly arranged at the top end face of the workbench, and the movable seat is slidably connected to the outer end face of the track. When the PE hose needs to be fixed and clamped, the PE hose is placed at the top end face of the movable seat, so that the first rubber pad is in contact with the bottom end face of the PE hose, and then the second rubber pad can be rotated through the setting relationship between the rotating rod and the open groove, so that the second rubber pad can be in contact with the top end face of the PE hose, and then the threaded rod is rotated. When the threaded rod moves down, it will drive the connecting block to move, and the PE hose is squeezed with the second rubber pad as the fulcrum. When the PE hose moves downward, it will force the first rubber pad and the support rod to move toward the inner direction of the groove. The first rubber pad can be deformed according to the outer side of the PE hose by utilizing the resilience of its telescopic spring.

[0004] Although this application can fix PE pipes, it has a single structure and is difficult to adapt to PE pipes of various thicknesses and pore sizes. At the same time, it can only fix one end of the PE. During the cutting process, the PE pipe is easily shaken, resulting in deviations in the cutting position. In addition, this application cannot freely adjust the cutting position, which is inconvenient in specific usage scenarios. For this reason, we propose a cutting device for PE hose production to solve the above-mentioned problems. Utility Model Content

[0029] The embodiment of the present application solves the problems in the prior art by providing a cutting device for PE hose production.

[0030] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0031] The specific structure of this embodiment is as follows: Figure 1-5 As shown, a cutting device for PE hose production includes a mounting assembly 1, which includes a base plate 101, two vertical plates 401 are arranged on both sides of the upper surface of the base plate 101, a cutting assembly 4 is arranged in the middle position of the two vertical plates 401, a clamping assembly 2 is arranged in a mirror image at both ends of the upper surface of the base plate 101 away from the two vertical plates 401, and two arc-shaped supporting plates 3 are arranged in a mirror image near the middle position of the upper surface of the base plate 101.

[0032] In some examples, four movable grooves 102 are mirrored on the upper surface of the base plate 101, four fixed rods 103 are mirrored on both sides of the inner wall of the base plate 101, one end of the four fixed rods 103 is fixedly connected to the inner wall of the base plate 101, two gears 104 are arranged inside the base plate 101, one end of each of the two gears is provided with a motor, and racks 105 are arranged at the upper and lower ends of the two gears 104, and the four racks 105 are respectively meshed with the two gears 104.

[0033] In some examples, the clamping assembly 2 includes a vertical rod 201, four vertical rods 201 are arranged on the upper surface of the base plate 101, the bottom ends of the four vertical rods 201 are respectively located in four movable grooves 102, four fixed rods 103 respectively pass through the four vertical rods 201 and are slidably connected to the four vertical rods 201, and the four vertical rods 201 are respectively fixedly connected to four racks 105.

[0034] In some examples, a fixed plate 202 is provided at one end of the four vertical rods 201 away from the fixed rod 103, a first sliding groove 203 is opened in the four fixed plates 202, a first arc-shaped clamping plate 206 is provided in the four first sliding grooves 203, a sliding rod 204 is fixedly connected in the four first sliding grooves 203, a first electric push rod 205 is provided between the four first arc-shaped clamping plates 206 and the four sliding grooves, and a second arc-shaped clamping plate 207 is fixedly connected near the bottom end of the four fixed plates 202.

[0035] The motor drives the gear 104 to rotate, so that the four racks 105 move on the two gears 104 respectively, driving the four vertical rods 201 to move toward the PE hose. When the four vertical rods 201 are close to the PE hose, the four first arc-shaped clamping plates 206 are driven by the four first electric push rods 205 to move toward the surface of the PE hose, which can adapt to PE hoses of various aperture sizes and clamp and fix them.

[0036] In some examples, two arc-shaped support plates 3 are disposed in a mirror image above the bottom plate 101 . The two arc-shaped support plates 3 are located in the middle of the four vertical rods 201 . A second electric push rod 301 is fixedly connected between the two arc-shaped support plates 3 and the bottom plate 101 .

[0037] The PE hose is placed on two arc-shaped support plates 3, and the second electric push rod 301 is used to drive the PE hose to rise and fall, so that the two ends of the PE hose are respectively located between the first arc-shaped clamping plate 206 and the second arc-shaped clamping plate 207 on both sides, which is convenient for placing the PE hose. When cutting, the arc-shaped support plate 3 can prevent the two sides of the PE hose from falling, thereby causing the other two ends to detach from the clamping assembly 2.

[0038] In some examples, the cutting assembly 4 includes a vertical plate 401, and the two vertical plates 401 are arranged in a mirror image. A second slide groove 402 is opened on one side of the two vertical plates 401, and a threaded rod 403 is arranged in the two second slide grooves 402. A motor is arranged at one end of one threaded rod 403, and the threaded rod 403 is fixedly connected to the rotating shaft of the motor. Both ends of the other threaded rod 403 are slidably connected to a second slide groove 402. A horizontal plate 404 is arranged in the middle of the two vertical plates 401, and both ends of the horizontal plate 404 are respectively located in the two second slide grooves 402, and the two threaded rods 403 respectively pass through the two threaded rods 403 and are threadedly connected to the horizontal plate 404.

[0039] The threaded rod 403 is driven to rotate by the motor. Since the cross plate 404 is threadedly connected to the threaded rod 403, the cross plate 404 moves on the threaded rod 403, so that the device can adjust the position of the cutting blade.

[0040] In some examples, a hydraulic rod 405 is fixedly connected to the lower surface of the horizontal plate 404, a protective box 406 is fixedly connected to the lower surface of the hydraulic rod 405, a cutting motor is arranged in the protective box 406, a cutting tool 407 is arranged on one side of the protective box 406, a rotating shaft of the cutting motor passes through the surface of the protective box 406 and is fixedly connected to the cutting tool 407, a door is arranged on the side of the protective box 406 away from the cutting tool 407, a spring 408 is fixedly connected to the lower surface of the protective box 406, and an arc-shaped pressure plate 409 is fixedly connected to the end of the spring 408 away from the protective box 406.

[0041] The protective box 406 is driven downward by the hydraulic rod 405 to make the arc-shaped pressure plate 409 close to the surface of the PE hose. At this time, the cutting motor is turned on and the PE hose is cut by the cutting tool 407. Since a spring 408 is connected between the arc-shaped pressure plate 409 and the protective box 406, it can play a secondary role in fixing the PE hose, thereby preventing inaccurate cutting position due to shaking of the protective box 406.

[0042] In a specific application scenario, the PE hose is first placed on two arc-shaped support plates 3, and the second electric push rod 301 is used to drive the PE hose to rise and fall, so that the two ends of the PE hose are respectively located between the first arc-shaped clamping plates 206 and the second arc-shaped clamping plates 207 on both sides, and the motor drives the gear 104 to rotate, so that the four racks 105 move on the two gears 104 respectively, and drive the four vertical rods 201 to move toward the PE hose. When the four vertical rods 201 are close to the PE hose, the four first arc-shaped clamping plates 206 are driven by the four first electric push rods 205 to move toward the surface of the PE hose, so that the clamping assembly 2 adapts to the size of the PE hose and clamps and fixes it. After being fixed, the threaded rod 403 is driven to rotate by the motor. Since the cross plate 404 is threadedly connected to the threaded rod 403, the cross plate 404 moves on the threaded rod 403, so that the device can adjust the position of the cutting blade. When the cutting position is adjusted, the protective box 406 is driven downward by the hydraulic rod 405 to make the arc-shaped pressure plate 409 close to the surface of the PE hose. At this time, the cutting motor is turned on and the PE hose is cut by the cutting tool 407. Since a spring 408 is connected between the arc-shaped pressure plate 409 and the protective box 406, the PE hose can be fixed for a second time to prevent inaccurate cutting position due to shaking of the protective box 406.

[0043] By adopting the above technical scheme: not only can the clamping component 2 be provided so that the device can adapt to PE hoses of various aperture sizes and clamp and fix them, but also the arc-shaped support plate 3 can be provided so that the device can prevent the two sides of the broken PE hose from falling during the cutting process, thereby causing the other two ends to detach from the clamping component 2. The vertical plate 401 can also be provided so that the device can adjust the position of the cutting blade, and the cutting component 4 can be provided so that the PE hose can be cut while preventing the inaccurate cutting position caused by the shaking of the protective box 406.

[0044] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
