Description

Technical Field

[0001] This invention relates to the field of cable insulation treatment technology, specifically to a cable insulation thermal stripping machine and its thermal stripping method. Background Technology

[0002] Cables are a general term for items such as optical cables and electrical cables. Cables have many uses, primarily for control installation, equipment connection, and power transmission, making them a common and indispensable part of daily life. During the production process, cable manufacturers often have unfinished or finished cables that need to be stripped of their insulation. Cable stripping machines can be used to remove the insulation and sheath of cables of various specifications.

[0003] However, existing cable insulation hot stripping technologies still have certain problems. When using existing hot stripping equipment to peel off the cable insulation, the insulation on the cable surface is melted by heating to achieve detachment. In this process, because the position of the cable hot stripping mechanism in the machine is fixed, it is impossible to select different positions on the cable for hot stripping according to needs. This makes it impossible for the hot stripping equipment to perform targeted hot stripping on cables of different specifications. At the same time, if the cable core is damaged after the insulation melts during use, the cable cannot be detected in time, making it difficult to detect internal functional damage to the cable in a timely manner. Summary of the Invention

One end of the top of the positioning column is slidably mounted inside the movable seat, and a first clamping block is fixedly connected to the opposite side of the movable seat and the base.

[0011] Preferably, the positioning and peeling mechanism includes two U-shaped plates, which are respectively installed on the top of the base and the bottom of the movable seat. An air pump is installed on the top of the frame. An air cylinder is fixedly connected inside the U-shaped plates. The air outlet of the air pump is connected to a solenoid valve. The air outlet of the solenoid valve is connected to a three-way pipe. The other two ports of the three-way pipe are connected to the inside of the air cylinder. A piston rod is slidably installed inside the air cylinder. A return spring is sleeved on the outside of the piston rod. One end of the piston rod passes through the air cylinder and is fixedly connected to a movable block. An arc-shaped groove is provided on an adjacent side of the two movable blocks, and an arc-shaped soft sheet is fixedly connected in the arc-shaped groove. An electric heating element is installed on the concave surface of the arc-shaped soft sheet.

[0012] Preferably, the cable shearing mechanism includes two second clamping blocks. The bottom of the movable base is provided with a sliding groove. One of the second clamping blocks is slidably installed in the sliding groove. The top of the base is provided with a groove, and an electric push rod is installed in the groove.

[0014] Preferably, the control output terminal of the microcontroller is connected to the electrical control terminals of the solenoid valve, the electric push rod, and the air pump; one end of the test terminal is connected to the signal input terminal of the microcontroller via a signal line; and the signal output terminal of the microcontroller is connected to the signal input terminal of the touch screen.

[0015] Preferably, a connecting plate is fixedly connected to the top of the movable seat.

[0016] Preferably, a cover is installed on the top of the frame, and the air pump is located inside the cover.

[0017] Preferably, a limiting block is fixedly connected to one end of the positioning post.

[0018] This invention also provides a method for hot stripping cable insulation using a hot stripping machine, comprising the following steps:

[0019] S1. After the cable is delivered to the top of the base, the movable seat is driven down to the top of the base by starting the external drive device, and the cable is fixed between the base and the movable seat. The first clamp and the second clamp are used to clamp and fix the left and right points on the surface of the cable.

[0020] S2. Before clamping and fixing the cable, start the air pump to deliver gas to the solenoid valve. The gas is delivered to the three-way pipe through the solenoid valve and finally enters the air cylinder to control the pressure of the piston rod. The solenoid valve can regulate the air pressure delivered in the three-way pipe to keep the air pressure in the three-way pipe balanced.

[0021] S3. The movable block at one end of the piston rod moves left and right under the control of gas pressure, which changes the position of the arc-shaped soft sheet and the heating sheet, thereby changing the position of the cable hot stripping point. Different positions on the cable can be selected for hot stripping operation according to different needs.

[0022] S4. After the heat stripping process, the cable insulation melts and breaks. The electric push rod is activated to drive the housing to move outward. The housing moves two second clamping blocks through the connecting rod. At the same time, the broken end of the cable insulation is dragged outward, so that the insulation is removed from the melted part, making it easy to recycle the melted insulation.

[0023] S5. In order to avoid damage to the core function of the cable during operation, one end of the cable is always connected to the test terminal through the base, and the communication function of the core is tested by the probe inside the test terminal.

[0024] S6. In S1-S5, the microcontroller installed in the control cabinet can control the solenoid valve, air pump and electric push rod, and control the air intake and exhaust volume of the solenoid valve through preset program, and receive the signal transmitted by the probe in the test terminal and display it on the touch screen.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. When using this invention, the gas is delivered to the solenoid valve by starting the air pump. The gas is then delivered to the three-way pipe through the solenoid valve and finally enters the air cylinder to control the pressure of the piston rod. The solenoid valve can regulate the gas pressure delivered in the three-way pipe to maintain the gas pressure balance. The movable block at one end of the piston rod moves left and right under the control of the gas pressure, changing the position of the arc-shaped soft sheet and the heating plate, thereby changing the position of the cable heat stripping point. According to different needs, different positions can be selected on the cable for heat stripping operation, allowing this invention to perform heat stripping on cables of different specifications. The heat stripping position can be changed at any time according to the needs, improving the heat stripping efficiency.

[0027] 2. The microcontroller installed in the control cabinet can control the solenoid valve, air pump and electric push rod. One end of the cable is always connected to the test terminal through the base. The probe inside the test terminal detects the communication function of the wire core. The microcontroller receives the signal transmitted by the probe inside the test terminal and displays it on the touch screen. This invention can avoid damage to the wire core function when the cable insulation is hot stripped. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1

[0037] Please see Figures 1-6 The present invention provides a cable insulation stripping machine, comprising: a frame 3, a cable pressing mechanism, a positioning and stripping mechanism, a cable stripping mechanism, and a detection and control mechanism.

[0038] The cable crimping mechanism is installed on the top of the frame 3. The cable crimping mechanism includes a base 1. The base 1 is fixedly installed on the top of the frame 3. A movable seat 2 is provided on the top of the base 1. Two positioning columns 17 are symmetrically fixedly connected to the top of the base 1. One end of the top of the positioning column 17 is slidably installed inside the movable seat 2. A first clamping block 10 is fixedly connected to the opposite side of the movable seat 2 and the base 1. After the cable is transported to the top of the base 1, the movable seat 2 is driven to press down to the top of the base 1 by starting the external drive device, and the cable is fixed between the base 1 and the movable seat 2. The first clamping block 10 and the second clamping block 14 are used to clamp and fix the left and right points on the surface of the cable.

[0039] The positioning and hot stripping mechanism is installed inside the cable crimping mechanism. This mechanism includes two U-shaped plates 12, which are respectively installed on the top of the base 1 and the bottom of the movable seat 2. An air pump 6 is installed on the top of the frame 3. An air cylinder 20 is fixedly connected inside the U-shaped plates 12. The air outlet of the air pump 6 is connected to a solenoid valve 8, and the air outlet of the solenoid valve 8 is connected to a three-way pipe 9. The other two ports of the three-way pipe 9 are connected to the inside of the air cylinder 20. A piston rod 22 is slidably installed inside the air cylinder 20. A return spring 19 is sleeved on the outside of the piston rod 22. One end of the piston rod 22 passes through the air cylinder 20 and is fixedly connected to a movable block 2. 1. Both adjacent sides of the two movable blocks 21 are provided with arc-shaped grooves, and arc-shaped flexible sheets 27 are fixedly connected in the arc-shaped grooves. The concave surface of the arc-shaped flexible sheets 27 is equipped with heating elements 26. Before clamping and fixing the cable, the air pump 6 is started to deliver gas to the solenoid valve 8. The gas is delivered to the three-way pipe 9 through the solenoid valve 8 and finally enters the air cylinder 20 to play a pressure control role on the piston rod 22. The solenoid valve 8 can regulate the air pressure delivered in the three-way pipe 9. The movable block 21 at one end of the piston rod 22 moves left and right under the control of the gas pressure, so that the position of the arc-shaped flexible sheets 27 and the heating elements 26 changes, thereby changing the position of the hot stripped part of the cable.

[0040] The cable stripping mechanism is installed inside the cable pressing mechanism. The cable stripping mechanism includes two second clamping blocks 14.

A connecting rod 13 is fixedly connected to the outside of the second clamping block 14 located in the sliding groove 23. One end of the bottom of the connecting rod 13 penetrates the housing 24. After heat stripping, the cable insulation melts. By starting the electric push rod 25, the housing 24 is driven to move outward. The housing 24 drives the two second clamping blocks 14 to move through the connecting rod 13. At the same time, the movement pulls the melted end of the cable insulation outward, so that the insulation is removed from the melted part, which facilitates the recycling of the melted insulation.

[0041] In this embodiment, the detection control mechanism is mounted on the frame 3. The detection control mechanism includes a control cabinet 4, which is mounted on the front surface of the frame 3. A touch screen 5 is embedded in the front surface of the control cabinet 4. A bracket 18 is mounted on one side of the base 1. A test terminal 15 is embedded inside the bracket 18, and a probe 28 is installed inside the test terminal 15. A microcontroller is installed inside the control cabinet 4. The control output terminal of the microcontroller is connected to the electrical control terminals of the solenoid valve 8, the electric push rod 25, and the air pump 6. One end of the test terminal 15 is connected to the signal input terminal of the microcontroller through a signal line. Furthermore, the signal output terminal of the microcontroller is connected to the signal input terminal of the touch screen 5. To prevent damage to the core of the cable during operation, one end of the cable is always connected to the test terminal 15 through the base 1. The probe 28 inside the test terminal 15 tests the communication function of the core. The microcontroller installed in the control cabinet 4 can control the solenoid valve 8, the air pump 6, and the electric push rod 25. It can control the air intake and exhaust volume of the solenoid valve 8 through a preset program and receive the signal transmitted by the probe 28 inside the test terminal 15, which is then displayed on the touch screen 5.

[0042] like Figures 1-6 As shown, a connecting plate 11 is fixedly connected to the top of the movable seat 2. The connecting plate 11 can install the movable seat 2 in an external drive device, and the external drive device can drive the movable seat 2 to move up and down. A cover 7 is installed on the top of the frame 3. The air pump 6 is located inside the cover 7. The cover 7 can protect the air pump 6 and prevent the air pump 6 from being exposed to the outside. A limit block 16 is fixedly connected to one end of the top of the positioning column 17. The limit block 16 can prevent the positioning column 17 from detaching from the movable seat 2.

[0043] Example 2

[0044] This embodiment also provides a method for hot stripping cable insulation using a hot stripping machine, including the following steps:

[0045] S1. After the cable is delivered to the top of the base 1, the movable seat 2 is driven down to the top of the base 1 by starting the external drive device, and the cable is fixed between the base 1 and the movable seat 2. The first clamping block 10 and the second clamping block 14 are used to clamp and fix the left and right points on the surface of the cable.

[0046] S2. Before clamping and fixing the cable, the air pump 6 is started to deliver gas to the solenoid valve 8. The gas is delivered to the three-way pipe 9 through the solenoid valve 8 and finally enters the air cylinder 20 to play a pressure control role on the piston rod 22. The solenoid valve 8 can regulate the air pressure delivered in the three-way pipe 9 to keep the air pressure in the three-way pipe 9 balanced.

[0047] S3. The movable block 21 at one end of the piston rod 22 moves left and right under the control of gas pressure, which changes the position of the arc-shaped soft sheet 27 and the heating sheet 26, thereby changing the position of the cable hot stripping point. Different positions on the cable can be selected for hot stripping operation according to different needs.

[0048] S4. After the heat stripping process, the cable insulation melts and the electric push rod 25 drives the housing 24 to move outward. The housing 24 drives the two second clamping blocks 14 to move through the connecting rod 13. At the same time, the melted end of the cable insulation is dragged outward, so that the insulation is removed from the melted part, making it easy to recycle the melted insulation.

[0049] S5. In order to avoid damage to the core function of the cable during operation, one end of the cable is always connected to the test terminal 15 through the base 1, and the core communication function is tested by the probe 28 inside the test terminal 15.

[0050] S6. In S1-S5, the microcontroller installed in the control cabinet 4 can control the solenoid valve 8, the air pump 6 and the electric push rod 25, and control the air intake and exhaust of the solenoid valve 8 through a preset program, and receive the signal transmitted by the probe 28 in the test terminal 15 and display it on the touch screen 5.

[0051] Based on the above technical solution, the working steps of this solution are summarized as follows: After the cable is delivered to the top of the base 1, the movable seat 2 is driven down to the top of the base 1 by starting the external drive device, and the cable is fixed between the base 1 and the movable seat 2. The first clamping block 10 and the second clamping block 14 are used to clamp and fix the left and right points on the surface of the cable.

[0052] Before clamping and fixing the cable, the air pump 6 is started to deliver gas to the solenoid valve 8. The gas is then delivered through the solenoid valve 8 to the three-way pipe 9 and finally enters the air cylinder 20 to control the pressure of the piston rod 22. The solenoid valve 8 can regulate the air pressure delivered in the three-way pipe 9 to maintain the air pressure balance. The movable block 21 at one end of the piston rod 22 moves left and right under the control of the gas pressure, changing the position of the arc-shaped flexible sheet 27 and the heating element 26, thereby changing the position of the cable heat stripping point. Different positions on the cable can be selected for heat stripping operation according to different needs.

[0053] After heat stripping, the cable insulation melts. The electric push rod 25 drives the housing 24 to move outward. The housing 24 moves the two second clamping blocks 14 through the connecting rod 13. At the same time, the melted end of the cable insulation is dragged outward to remove the insulation from the melted point, making it easy to recycle the melted insulation. In order to avoid damage to the core function of the cable during operation, one end of the cable is always connected to the test terminal 15 through the base 1. The probe 28 inside the test terminal 15 tests the communication function of the core.

[0054] The microcontroller installed in the control cabinet 4 can control the solenoid valve 8, the air pump 6 and the electric push rod 25. It can control the air intake and exhaust of the solenoid valve 8 through a preset program, and receive the signal transmitted by the probe 28 in the test terminal 15 and display it on the touch screen 5.

[0055] All parts not described in this invention are the same as or can be implemented using existing technology. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
