Description

Technical Field

[0001] The invention relates to the technical field of cables, in particular to a longitudinal watertight cable cabling and glue injection device. Background Art

[0002] Watertight cables are an important part of sonar equipment. According to the sealing method, they are divided into two types: transverse watertight cables and longitudinal watertight cables. Longitudinal watertight cables use water-blocking glue to slow down the flow of water inside the cable when the sheath is damaged, thereby improving the reliability of the equipment.

[0003] Since the gaps in the longitudinal watertight cable cores are relatively large during the cabling process, they need to be filled with water-blocking glue. However, the existing cable cabling process usually relies on manual glue injection, but this method has a slow injection speed, high time consumption, uncontrollable glue output, and poor uniformity and stability. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the problem that the cable cabling process in the prior art relies on manual glue injection, resulting in poor glue injection uniformity and stability.

[0005] In order to solve the above technical problems, the present invention provides a longitudinal watertight cable cabling glue injection device, comprising: The support adjustment device comprises a bottom plate, a column mounted on the bottom plate, and a crossbeam connected to the top of the column in a transversely adjustable manner, a tray is mounted on the crossbeam, and a clearance channel is provided on the tray; A glue storage container, supported on the tray, storing water-blocking glue; A glue discharging assembly, comprising a glue discharging pipe passing through the give way channel and communicating with the bottom end of the glue storage container, and a glue discharging valve installed on the glue discharging pipe and used to control the glue discharging speed of the water-blocking glue in the glue storage container; The heating device is arranged on one side of the support and adjustment device, and includes a hot air pipe connected to the glue storage container. The heating device can introduce hot air into the glue storage container through the hot air pipe to heat the water-blocking glue.

[0006] In one embodiment of the present invention, the heating device includes a shell, a heater disposed in the shell, and a fan installed on one side wall of the shell, and the hot air pipe is installed on the other side wall of the shell opposite to the fan.

[0007] In one embodiment of the present invention, a support frame is further included, and the shell is placed on the support frame.

[0008] In one embodiment of the present invention, an opening for inserting the hot air pipe is provided on the side wall of the glue storage container, and the opening is higher than the liquid level of the glue in the glue storage container.

[0009] In one embodiment of the present invention, the housing is provided with control buttons for controlling the heater and the fan.

[0010] In one embodiment of the present invention, a locking sleeve for the crossbeam to pass through is arranged at the top end of the column, and a locking screw is arranged on the locking sleeve.

[0011] In one embodiment of the present invention, a reinforcing diagonal brace is provided between the base plate and the column.

[0012] In one embodiment of the present invention, the glue storage container is barrel-shaped, a pull ear extends from the side wall of the glue storage container, a cover with a handle is provided on the top, and a vent hole or a vent valve is provided on the cover.

[0013] In one embodiment of the present invention, a liquid level sensor and a temperature sensor are provided on the glue storage container to monitor the liquid level and temperature of the water-blocking glue in real time.

[0014] In one embodiment of the present invention, the glue outlet pipe is connected to the bottom end of the glue storage container by threaded connection or welding.

[0015] The above technical solution of the present invention has the following advantages compared with the prior art: The longitudinal watertight cable cabling glue injection device described in the present invention can accurately inject water-blocking glue into the gap of the cabling wire core through the cooperation of the support adjustment device and the glue output component, thereby avoiding the problems of unstable glue output and poor glue injection uniformity during manual glue injection. Compared with manual glue injection, the glue injection efficiency of this device is high and the speed is fast, which significantly reduces manpower input and shortens the production cycle. In a low temperature environment, the viscosity of the water-blocking glue is relatively large and the fluidity is poor. The hot air is introduced into the glue storage container by the heater and the fan, so that the water-blocking glue is kept in a suitable temperature range and has better fluidity, thereby further improving the efficiency and uniformity of glue injection, and the heating temperature can be flexibly adjusted in different seasons or temperature environments to meet various production needs.

[0016] Through the coordination of the bottom plate, columns, cross beams, reinforced diagonal braces and other components, the entire device has the characteristics of good stability and small footprint. The position and height can be adjusted according to the on-site environment of the cabling machine. The equipment combination is simple to assemble and disassemble and easy to move.

Those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0024] Reference Figure 1 As shown, a longitudinal watertight cable cabling and glue injection device of the present invention comprises: The support and adjustment device 1 comprises a bottom plate 11, a column 12 mounted on the bottom plate 11, and a crossbeam 13 connected to the top of the column 12 in a transversely adjustable manner, a tray 14 is mounted on the crossbeam 13, and a clearance passage is provided on the tray 14; The glue storage container 2 is supported on the tray 14 and stores water-blocking glue; The glue discharging component 3 comprises a glue discharging pipe 31 passing through the give way channel and connected to the bottom end of the glue storage container 2, and a glue discharging valve 32 installed on the glue discharging pipe 31 and used to control the glue discharging speed of the water-blocking glue in the glue storage container 2; the water-blocking glue flows into the glue discharging pipe 31 by gravity, and the glue discharging amount can be accurately controlled by the adjustment function of the glue discharging valve 32, and fine-tuned in real time according to the running speed of the cabling machine and the wire core structure, so as to ensure more uniform filling of the colloid and reduce defects; The heating device 4 is arranged on one side of the supporting and adjusting device 1, and includes a hot air pipe 41 connected to the glue storage container 2. The heating device 4 can introduce hot air into the glue storage container 2 through the hot air pipe 41 to heat the water-blocking glue.

[0025] Through the cooperation of the support adjustment device 1 and the glue discharging component 3, the water-blocking glue can be accurately injected into the gap of the cable core, avoiding the problems of unstable glue output and poor glue injection uniformity during manual glue injection. Compared with manual glue injection, the glue injection efficiency of this device is high and the speed is fast, which significantly reduces manpower input and shortens the production cycle. The glue discharging valve 32 is used to accurately control the glue discharging speed, which can be fine-tuned according to on-site needs, avoiding excessive or insufficient glue injection, while improving the uniformity of the distribution of the water-blocking glue in the cable and improving the quality stability after cabling. By adjusting the glue discharging direction and the pipeline position laterally, it is ensured that the gaps between the multiple cores are fully filled.

[0026] For example, the glue outlet valve 32 may be a spiral regulating valve, a regulating ball valve, a proportional control valve, a needle valve, a gate valve, etc.

[0027] In one embodiment, the heating device 4 includes a shell, a heater 42 disposed in the shell, and a fan 43 installed on one side wall of the shell, and the hot air pipe 41 is installed on the other side wall of the shell opposite to the fan 43.

[0028] Specifically, a temperature sensor is provided in the heater 42, and the temperature in the barrel is accurately controlled by a PLC or a temperature controller. A variable frequency fan 43 is used to control the air volume to meet different viscosity and temperature requirements.

[0029] Since the water-blocking glue has a high viscosity and poor fluidity in a low temperature environment, the heater 42 cooperates with the fan 43 to introduce hot air into the glue storage container 2, so that the water-blocking glue is kept in a suitable temperature range and has better fluidity, thereby further improving the glue injection efficiency and uniformity. The heating temperature can be flexibly adjusted in different seasons or temperature environments to meet various production needs.

[0030] In one embodiment, a support frame 44 is further included, and the shell is placed on the support frame 44 .

[0031] In one embodiment, an opening is provided on the side wall of the glue storage container 2 for inserting the hot air pipe 41, and the opening is higher than the liquid level of the glue in the glue storage container 2. The opening is arranged in the upper middle part of the glue storage container 2 or close to the top of the container to ensure that when a certain amount of glue is contained in the glue storage container 2, the liquid level of the glue is lower than the opening. In this way, even if the glue in the container is stirred by hot air, it will not easily churn or surge to the pipe mouth of the hot air pipe.

[0032] In addition, when the fan 43 of the heating device 4 blows hot air to the glue storage container 2, the interior of the glue storage container 2 is in a slightly positive pressure state, and the airflow enters the glue storage container 2 in one direction from the hot air pipe 41 to avoid reverse suction. Under positive pressure, the glue is prevented from flowing back or refluxing along the hot air pipe 41.

[0033] The hot air pipe 41 is connected to the side wall of the glue storage container 2 in a transverse direction.

[0034] In one embodiment, the housing is provided with a control button 45 for controlling the heater 42 and the fan 43 , or a human-computer interaction screen, etc.

[0035] Through the above arrangement, the heated hot air is sent into the glue storage container 2 through the fan 43, avoiding local overheating or condensation caused by direct heating, and improving safety and heating uniformity. The hot air pipe 41 enters the side wall of the glue storage container 2 in the horizontal direction, and the air guide direction can be flexibly set according to the actual needs in the barrel. A control button 45 is set on the shell, which can monitor and adjust the working status of the fan 43 and the heater 42 at any time, which is convenient for human-computer interaction.

[0036] In one embodiment, a locking sleeve 15 is provided at the top of the column 12 for the crossbeam 13 to pass through, and a locking screw 16 is provided on the locking sleeve 15. The size of the front and rear ends of the crossbeam 13 can be controlled by the tightness of the locking sleeve 15, so that the glue outlet pipe 31 can be adjusted laterally to adjust the glue outlet direction. The locking sleeve 15 with the locking screw 16 is used to fix the position of the crossbeam 13. After adjustment, the crossbeam 13 is fixed reliably to avoid the glue outlet direction being offset due to vibration or external force during the glue injection process.

[0037] In one embodiment, a reinforcing diagonal brace 17 is provided between the base plate 11 and the upright column 12. In addition, a slide rail or casters are installed on the base plate 11 to facilitate rapid movement between different production stations.

[0038] In one embodiment, the glue storage container 2 is barrel-shaped, a pull ear 21 is extended from the side wall of the glue storage container 2, and a cover 23 with a handle 22 is provided on the top to facilitate the operator to carry.

[0039] In addition, a vent hole (or vent valve) is provided on the sealing cover 23. After the hot air pipe 41 delivers the hot air into the glue storage container 2, the hot air will contact with the glue liquid in the glue storage container 2 and perform heat exchange. When the internal air pressure of the glue storage container 2 is slightly higher than that of the outside, the excess hot air can be discharged through the vent hole on the sealing cover 23, thereby realizing the circulation and discharge of hot air and maintaining the pressure balance inside and outside the glue storage container 2.

[0040] In one embodiment, a liquid level sensor and a temperature sensor are also provided on the glue storage container 2 (on the inner wall) to realize real-time monitoring of the liquid level or temperature of the water-blocking glue, and display the value on an external human-computer interaction screen. When the temperature detected by the temperature sensor is lower than the threshold value, the heating device 4 is controlled by the PLC controller to heat the water-blocking glue in the glue storage container 2.

[0041] In one embodiment, a scale or a transparent observation window is provided on the outer surface of the barrel body to facilitate accurate observation of the remaining amount of colloid so as to replenish it in time when the glue is insufficient. Furthermore, the glue storage container 2 can be selected to have a double-layer insulation structure, and cooperate with the heating device 4 to further maintain the temperature of the colloid stable.

[0042] In one embodiment, the rubber outlet pipe 31 is connected to the bottom end of the rubber storage container 2 by threaded connection or welding. Through the coordination of the bottom plate 11, the column 12, the crossbeam 13, the reinforcing diagonal brace 17 and other components, the entire device has the characteristics of good stability and small footprint, and can be adjusted in position and height according to the on-site environment of the cabling machine. The equipment combination is simple to assemble and disassemble, easy to move, and can adapt to cabling machines of different types and specifications, with good scalability.

[0043] Working principle of the present invention: First, place the bottom plate 11 supporting the adjusting device 1 at a suitable position near the cabling machine to ensure its stability; Open the cover 23 of the glue storage container 2, pour the prepared water-blocking glue into the glue storage container 2, and ensure that the liquid level or weight meets the production requirements; Cover the cover 23 and insert the hot air pipe 41 into the inlet of the container side wall as needed; start the fan 43 and the heater 42 to blow hot air into the glue storage container 2 through the hot air pipe 41 to keep the water-blocking glue at a suitable temperature to maintain a suitable viscosity range; Adjust the length and direction (by adjusting the bottom plate 11) of the crossbeam 13, and then fix it with screws. When discharging glue, align the glue discharge pipe 31 with the gap of the cabling core, and fine-tune the glue discharge valve 32 to adapt to the cabling speed. When the cabling machine starts to twist or cable the cores, open the glue discharge valve 32 and gradually adjust the glue discharge speed to allow the water-blocking glue to be stably injected into the gaps of the cores. By observing the gluing condition of the cores or using monitoring instruments, fine-tune the glue discharge valve 32 in time to ensure good glue injection uniformity. After controlling the glue discharge amount, start the cabling machine. During the operation of the cabling machine, regularly check the remaining amount of colloid in the glue storage container 2, and replenish water-blocking glue when necessary.

[0044] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
