Description

Technical Field

[0001] This invention relates to the field of heat shrink tubing heating technology, and particularly to a detachable automatic heating device and method for using heat shrink tubing on cylindrical specimens. Background Technology

[0002] Heat shrink tubing is made by extruding ordinary polymer materials (polyvinyl chloride, polyethylene, etc.) into tubes, which are then heated to change their molecular structure and expand and shape. In rock mechanics tests (triaxial, NMR, and flow analysis), manual operation during the heating process can lead to heating failures and waste of heat shrink tubing, which is a serious problem. Furthermore, manual heating can cause uneven heating of the heat shrink tubing, resulting in poor adhesion to the specimen and potentially leading to inaccurate test results and data.

[0003] The existing method of manually rotating the sample through a single outlet of a hot air gun to heat the heat shrink tubing is prone to problems such as loose wrapping of the heat shrink tubing and burns caused by manual heating. Furthermore, it can affect the test results of the specimen in triaxial, nuclear magnetic resonance, and permeation tests, and may also cause the instrument to be affected by rock debris.

[0004] Therefore, a detachable cylindrical device for automatic heating of heat shrink tubing for standard cylindrical specimens is proposed, which improves the success rate and quality of heat shrinking, and obtains more accurate test results and data. Summary of the Invention

[0005] In view of the above-mentioned problems in the existing technology, the technical problem to be solved by the present invention is that the existing method of manually twisting and rotating the sample to heat the heat shrink tubing through a single air outlet of a hot air gun is prone to causing the heat shrink tubing to not wrap tightly.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A detachable cylindrical device for automatic heating of standard cylindrical heat shrink tubing specimens includes a transmitter mounting platform and an upper cylindrical device. The upper cylindrical device has an internal cavity. A receiver mounting platform is located on top of the upper cylindrical device. The upper cylindrical device is positioned above the transmitter mounting platform and is detachably connected to the transmitter mounting platform. The transmitter mounting platform has a transmitter mounting platform surface on its top. A specimen positioning piece is located inside the transmitter mounting platform surface. The specimen positioning piece corresponds to the position of the cavity. An infrared receiver is located on the inner surface of the receiver mounting platform. An infrared emitting ring is located on the outer side of the specimen positioning piece. The infrared receiver and the infrared emitting ring are coaxially arranged.

[0008] The inner wall of the upper cylindrical device is provided with a heating module that can move up and down along the axis of the upper cylindrical device.

[0009] Specifically, it also includes a control module and a moving mechanism that drives the heating module to move. The control module is connected to the heating module, the moving mechanism, the infrared receiver, and the infrared emitting coil, respectively.

[0010] Specifically, the transmitter mounting platform and the upper cylindrical device are detachably connected via mounting clips.

[0011] A method for using a detachable cylindrical device for automatic heating of heat shrink tubing for standard cylindrical specimens, employing the aforementioned detachable cylindrical device for automatic heating of heat shrink tubing for standard cylindrical specimens, includes the following steps:

[0012] S1: Prepare the test specimen, selecting a standard cylindrical specimen of the specified dimensions;

[0013] S2: Place the heat shrink tubing over the specimen and position it on the specimen positioning piece.

[0014] S3: The transmitter mounting platform is installed together with the upper cylindrical device by means of the mounting clips and placed on the loading platform surface.

[0015] S4: Set the temperature of the heating module through the control module, and start the moving mechanism through the control module. The moving mechanism controls the movement of the heating module to start heating the heat shrink tubing from bottom to top.

[0016] S5: After heating, the infrared emitting ring is controlled by the control module to emit infrared rays, and the infrared receiver receives the signal. If the infrared receiver does not receive the signal, it means that the heat shrink tubing is not heated tightly and there is a bulge. Then repeat step S4; otherwise, proceed to S6.

[0017] S6: Remove the upper cylindrical device and the transmitter mounting platform.

[0018] Compared with the prior art, the present invention has at least the following advantages:

[0019] 1. This invention sets up a transmitter mounting platform, installs the test specimen at the center of the platform, and then sets up an upper cylindrical device detachably connected to the platform. A heating module that can move up and down along its axis is set on the inner wall of the upper cylindrical device. In use, the heating module moves up and down to achieve uniform heating of the test specimen and the heat shrink tubing wrapped around the test specimen. This eliminates the need to heat the test specimen by hand, solving the problems of uneven heating and burns caused by manual heating.

[0020] 2. This invention is a detachable device. It can be installed and used when some tests require heat shrink tubing. When heat shrink tubing tests are not required, the device can be detached and does not occupy test space, thus providing convenience for testing.

[0021] 3. This invention uses a ring of heating modules to automatically heat the heat shrink tubing from bottom to top, making the heating more uniform. Furthermore, infrared monitoring of the heat shrink tubing's wrapping properties greatly improves the success rate and quality of heat shrinking, resulting in more accurate test results and data.

Detailed Implementation

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] Example 1: See Figures 1-4A detachable cylindrical device for automatic heating of heat shrink tubing for standard cylindrical specimens, characterized in that it includes a transmitter mounting platform 6 and an upper cylindrical device 13, the upper cylindrical device 13 having an internal cavity, a receiver mounting platform 2 at the top of the upper cylindrical device 13, the upper cylindrical device 13 being located above the transmitter mounting platform 6, and the upper cylindrical device 13 being detachably connected to the transmitter mounting platform 6. The top of the transmitter mounting platform 6 is provided with a transmitter mounting platform surface 10. Inside the transmitter mounting platform surface 10 is a specimen positioning piece 11, which corresponds to the position of the placement cavity. The inner surface of the receiver mounting platform 2 is provided with an infrared receiver 3, and the outer side of the specimen positioning piece 11 is provided with an infrared emitting ring 7. The infrared receiver 3 and the infrared emitting ring 7 are coaxially arranged. The inner wall of the upper cylindrical device 13 is provided with a heating module 8 that can move up and down along the axis of the upper cylindrical device 13.

[0029] In practice, the specimen positioning piece 11 is used to install the specimen 5, the heat shrink tubing 4 is sleeved on the outside of the specimen 5, and the infrared emitting ring 7 is tightly attached to the outer wall of the heat shrink tubing 4. The specimen 5 is located inside the placement cavity of the upper cylindrical device 13.

[0030] In specific implementation, the heating module 8 uses a resistance heating wire, and the heating module 8 is annular on the outside. The heating module 8 is coaxially arranged with the placement cavity inside the upper cylindrical device 13. The control module controls the temperature of the resistance heating wire to facilitate heating of the heat shrink tubing.

[0031] The heating module can move up and down along the axis of the upper cylindrical device 13, thus enabling heating of the heat shrink tubing from bottom to top or top to bottom during use. Since the heating module is installed around the inner wall of the upper cylindrical device 13, it ensures uniform heating of the heat shrink tubing at the same height, guaranteeing a smooth and flat surface throughout. Additionally, an infrared emitting coil emits infrared light. Because the infrared emitting coil is mounted on the transmitter mounting platform at the bottom of the heat shrink tubing and is close to its outer wall, it emits infrared light. If the infrared receiver, coaxial with the infrared emitting coil, does not receive infrared light, it indicates that the surface of the heat shrink tubing is uneven or has bulges. These bulges block the emitted infrared coil, preventing the infrared receiver from receiving the light. The heating module can then be used again to heat the heat shrink tubing until the bulges disappear, ensuring a smooth and flat surface.

[0032] Specifically, it also includes a control module 1 and a moving mechanism that drives the heating module 8 to move [not shown in the figure]. The control module 1 is connected to the heating module 8, the moving mechanism, the infrared receiver 3, and the infrared emitting coil 7, respectively.

[0033] In a specific implementation, a device circuit 12 can be installed inside the transmitter mounting platform 6 to supply power to the entire device.

[0034] The moving mechanism is used to drive the heating module 8 to move up and down. The moving mechanism may include a motor, a lead screw and a slider. The heating module 8 is mounted on the slider. The output end of the motor is fixedly connected to the lead screw. The lead screw is fixedly mounted on the inner wall of the upper cylindrical device 13. The slider is threadedly connected to the lead screw.

[0035] The motor is a stepper motor. The control module 8 controls the start and stop of the motor. When the motor starts, the motor drives the lead screw to rotate. The rotation of the lead screw drives the slider to move on it, which in turn drives the heating module 8 to move along the axis of the upper cylindrical device 13.

[0036] Specifically, the transmitter mounting platform 6 is detachably connected to the upper cylindrical device 13 via mounting clips 9. A loading platform surface 14 is provided below the transmitter mounting platform 6.

[0037] By installing the clip 9, the transmitter mounting platform 6 and the upper cylindrical device 13 can be easily disassembled and installed when some tests require the heat shrink tubing 4. When the heat shrink tubing 4 is not required for the test, the device can be disassembled by installing the clip 9 without occupying test space, which provides convenience for the test.

[0038] Example 2:

[0039] See Figures 1-4 A method for using a detachable cylindrical device for automatic heating of heat shrink tubing for standard cylindrical specimens, employing the detachable cylindrical device for automatic heating of heat shrink tubing for standard cylindrical specimens as defined in Example 1, includes the following steps:

[0040] S1: Prepare specimen 5, select a standard cylindrical specimen of the specified size; for example, it can be a specimen of 50mm×100mm.

[0041] S2: Place the heat shrink tubing 4 onto the specimen 5 and position it on the specimen positioning piece 11.

[0042] S3: The transmitter mounting platform 6 is installed together with the upper cylindrical device 13 by means of the mounting buckle 9 and placed on the loading platform surface 14.

[0043] S4: Set the temperature of the heating module 8 through the control module 1, and start the moving mechanism through the control module 1. Control the heating module 8 to move through the moving mechanism to start heating the heat shrink tube 4 from bottom to top.

[0044] S5: After heating, the infrared emitting coil 7 is controlled by the control module 1 to emit infrared rays, and the infrared receiver 3 receives the signal. If the infrared receiver 3 does not receive the signal, it means that the heat shrink tubing 4 is not heated tightly and has bulges. Then repeat step S4; otherwise, proceed to S6.

[0045] S6: Remove the upper cylindrical device 13 and the transmitter mounting platform 6.

[0046] The working process of this invention is as follows: First, the heat shrink tubing 4 is fitted onto the specimen 5. Then, the specimen 5 is fixed at the specimen positioning piece 11. The transmitter mounting platform 6 and the upper cylindrical device 13 are assembled together using the mounting buckle 9. Subsequently, the device circuit 12 is powered on, and the moving mechanism (not shown in the diagram) drives the heating module 8 to move from bottom to top, heating the heat shrink tubing 4 from bottom to top. After heating is completed, the infrared emitting ring 7 is controlled by the control module 1 to emit infrared rays. If the infrared receiver 3 does not receive a signal, it indicates that the heat shrink tubing 4 is not heated tightly and there is a bulging phenomenon. Then, the heating module 8 is controlled by the control module 1 to continue heating the heat shrink tubing 4. At this time, the infrared emitting ring 7 continues to emit infrared rays. If the infrared receiver 3 receives a signal, it indicates that the heat shrink tubing 4 has been smoothed and tightened without bulging. At this time, the device circuit is cut off, and the upper cylindrical device 13 and the transmitter mounting platform 6 on the loading platform surface 14 are removed. Then, the transmitter mounting base 6 and the upper cylindrical device 13 that are installed together are disassembled.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
