Description

Technical Field

[0001] The utility model relates to the technical field of wire and cable manufacturing, in particular to a self-cleaning device for a cable diameter gauge. Background Art

[0002] In the manufacturing process of wire and cable, the extruder is a core piece of equipment used to evenly wrap insulation or protective layers around the conductor or inner shield. To ensure the dimensional consistency and stability of the extruded product, the extruder is typically equipped with a non-contact laser caliper, such as the bidirectional caliper for a sheathed cable production line disclosed in CN117739839A. During production, the cable passes through the center hole of the caliper, where a lens collects wire diameter data in real time and feeds this data back to a PLC (programmable logic controller) to precisely control the extrusion thickness.

[0003] However, in actual production, dust, smoke and other impurities in the workshop will gradually adhere to the lens surface of the diameter gauge, affecting the transmission and reception of laser signals, resulting in inaccurate wire diameter measurement.

[0004] At present, the cleaning of the lens mainly relies on manual regular cleaning, which not only increases the workload of maintenance personnel, but also easily interrupts the measurement process, affecting the continuity and accuracy of the measurement. Therefore, it is necessary to provide a self-cleaning device for the cable diameter gauge. Utility Model Content

[0032] (1) Clean air is transported through the air transmission channel. During the air transmission process, the cross-section of the air becomes smaller when passing through the circular tube, thereby increasing the flow rate. When the flow rate is large, negative pressure is obtained at the air outlet of the circular tube, generating suction, thereby making the dust suction channel have dust suction ability. When the end cover is installed on the annular caliper, the dust suction structure can be used to absorb pollutants on the lens of the annular caliper, thereby realizing self-cleaning of the lens and reducing the workload of maintenance personnel. The cleaning process is not easy to interrupt the measurement process, thereby ensuring the continuity and accuracy of the measurement.

[0033] (2) The round tube is clamped and fixed between the two half end covers, and the adjacent ends of the two half end covers are sealed and fixedly connected by gluing, which facilitates the assembly of the round tube.

[0034] (3) A plurality of dust suction channels are arranged in a circular array along the circumference of the through hole. The airflow is balanced by the shape, and the cable is not easily shaken during negative pressure adsorption.

[0035] (4) One end of the exhaust pipe is fixed on the end cover and connected to the air outlet, and the other end extends in a spiral shape around the central axis of the through hole, so that the air discharged from the air transmission channel can be reused through the exhaust pipe, and the cable can be pre-cleaned before entering the annular caliper. During pre-cleaning, the spirally wound gas will not be blown directly onto the cable when it is discharged from the exhaust pipe, but will flow around the cable on the outside of the cable, so that the cable will not be contaminated while being pre-cleaned.

DETAILED DESCRIPTION

[0044] The following will be combined with the specific embodiments of the present invention to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] like Figure 1-6 As shown, a self-cleaning device for a cable diameter gauge of the present invention comprises an end cover 1 and a round tube 2.

[0046] The end cover 1 is a circular plate-shaped structure, and a through hole 101 is provided in the middle of the plate-shaped structure. Figure 1 As shown, one end of the end cover 1 is fixedly connected to one end of the annular caliper 4 by a bolt, or by a structural adhesive. When connected, a sealing gasket is placed between the end cover 1 and the annular caliper 4. After connection, the through hole 101 of the end cover 1 is coaxially arranged with the annular caliper 4, as shown in FIG. Figure 1 As shown, when the cable 5 is transported, the cable 5 passes through the through hole 101 and passes through the inner side of the ring of the ring caliper 4, wherein the transport direction of the cable 5 is Figure 1 In the direction of the arrow shown in , a lens is provided on the inner side of the ring of the annular caliper 4 , and the lens is close to the through hole 101 .

[0047] like Figure 3 As shown, an air delivery channel 102 and a dust collection channel 103 are provided inside the end cover 1 .

[0048] The air delivery channel 102 is used to deliver clean compressed air, such as Figure 3-5 As shown, the air inlet end of the air delivery channel 102 passes through the outer portion of the end cap 1, and the air outlet end passes through the end of the end cap 1 away from the annular caliper 4. A gas line connector is threaded onto the air inlet end of the air delivery channel 102. The gas line connector is a commercially available PC04 series gas line connector, or other types of gas line connectors. The gas line connector threaded onto the air inlet end of the air delivery channel 102 is used to connect to the gas pipeline of the gas source. When the gas source delivers compressed air through the pipeline toward the gas line connector, the compressed air enters the air inlet end of the air delivery channel 102 and exits the air outlet end. In this structure, the provision of the gas line connector facilitates the connection of the air delivery channel 102 to the gas source.

[0049] The dust suction channel 103 is used to suck the pollutants on the surface of the lens, and is also used to suck the suspended pollutants in the space around the lens, reducing the impact of pollutants on cable production efficiency and product quality. Figure 3-5As shown, the suction end of the dust suction channel 103 passes through the hole wall of the through hole 101 and forms a dust suction port 1031, and the exhaust end is connected to the side of the air supply channel 102. During suction, pollutants are sucked into the suction end of the dust suction channel 103, and then enter the air supply channel 102 from the exhaust end of the dust suction channel 103 and are discharged with the airflow in the air supply channel 102.

[0050] To achieve the suction capacity of the dust suction channel 103, as Figure 3-5 As shown, the circular tube 2 is arranged in the air supply channel 102 between the air inlet end of the air supply channel 102 and the exhaust end of the dust suction channel 103, and one end of the circular tube 2 is arranged at the exhaust end of the dust suction channel 103. The circular tube 2 is used to form a negative pressure at the part of the air supply channel 102 close to the dust suction channel 103, thereby enabling the dust suction channel 103 to have suction capability.

[0051] In addition, the dust suction channel 103 is in the shape of a straight hole, wherein Figure 5 As shown, the dust suction channel 103 is parallel to the radial direction of the end cover 1, or, as shown in FIG. Figure 3 As shown, the dust suction channel 103 forms an angle of 30 degrees to 90 degrees with the radial direction of the end cover 1, wherein, Figure 3 In the figure, the angle between the dust suction channel 103 and the radial direction of the end cover 1 is 45 degrees. Through this angle structure, the compressed air in the air supply channel 102 will not directly impact the exhaust end of the dust suction channel 103, so that the airflow in the dust suction channel 103 can be more easily brought into the air supply channel 102, thereby making the dust suction channel 103 have better suction capacity.

[0052] To facilitate the assembly of the round tube 2, Figure 4-5 As shown, the end cover 1 is divided into two halves along the first preset plane, wherein the first preset plane is a virtual plane parallel to the axial direction of the first straight hole portion 1021 and intersecting with the axial direction of the first straight hole portion 1021. The circular tube 2 is clamped and fixed between the two halves of the end cover 1, and the adjacent ends of the two halves of the end cover 1 are sealed and fixedly connected by gluing. In addition, in this structure, Figure 4-5 As shown, air delivery grooves and dust collection grooves are provided on the opposite ends of the two half end covers 1. When the two half end covers 1 are docked and fixed, the air delivery grooves on the two half end covers 1 are assembled into a complete air delivery channel 102, and the dust collection grooves on the two half end covers 1 are assembled into a complete dust collection channel 103.

[0053] like Figure 3-5 As shown, in the above-mentioned gas transmission channel 102 , the gas transmission channel 102 includes a first straight hole portion 1021 , an arc hole portion 1022 and a second straight hole portion 1023 .

[0054] Among them, such as Figure 3 As shown, the first straight hole portion 1021 is parallel to the radial direction of the end cover 1, and the arc hole portion 1022 is concentric with the end cover 1. Figure 5As shown, the second straight hole portion 1023 is parallel to the axial direction of the end cover 1 .

[0055] The first straight hole portion 1021 is used to introduce compressed air, such as Figure 3 As shown, it is arranged in an L shape with the arc hole portion 1022 and is connected, and one end thereof passes through the outer wall of the end cover 1 and forms an air inlet 1024, wherein the air inlet 1024 is used to connect to the output port of the air source, the circular tube 2 is embedded in the arc hole portion 1022, and the exhaust end of the dust suction channel 103 is connected to the side of the arc hole portion 1022.

[0056] The second straight hole portion 1023 is used to discharge the air in the gas transmission channel 102. It is arranged in an L shape with the arc hole portion 1022 and is connected. One end of the second straight hole portion 1023 passes through one end of the end cover 1 and forms an air outlet 1025. Figure 5 As shown, the air in the air delivery channel 102 is eventually discharged from the air outlet 1025 .

[0057] like Figure 5 As shown, in the above-mentioned arc hole portion 1022, the arc hole portion 1022 forms a normal pressure channel 1026 and a negative pressure channel 1027 through the circular tube 2, wherein the normal pressure channel 1026 and the negative pressure channel 1027 are connected through the circular tube 2, and the normal pressure channel 1026 is connected to the first straight hole portion 1021, and the negative pressure channel 1027 is connected to the second straight hole portion 1023. When the compressed air enters from the air inlet 1024, it first passes through the normal pressure channel 1026 and then passes through the circular tube. 2 enters the negative pressure channel 1027. During this process, the cross-section of the compressed air becomes smaller when passing through the circular tube 2, so the flow rate becomes faster. When the circular tube 2 is close to one end of the negative pressure channel 1027 to discharge air, negative pressure occurs at this part, generating suction, which can then absorb pollutants through the dust collection channel 103. After the pollutants are sucked into the negative pressure channel 1027, they are discharged from the air outlet 1025 along with the air flow. In addition, by adjusting the intake pressure of the air inlet 1024, different negative pressure adsorption forces can be obtained.

[0058] In actual application, in order to balance the airflow and prevent the cable 5 from shaking when the negative pressure adsorbs pollutants, Figure 3 As shown, there are several dust suction channels 103 in a circumferential annular array along the through hole 101. Figure 3 There are four dust suction channels 103 shown in the figure, and there may also be two, three or more. An air delivery channel 102 is set at each dust suction channel 103, and a circular tube 2 is set in each air delivery channel 102.

[0059] In addition, at the production site, dust, impurities and other pollutants on the surface of the annular caliper 4 mainly come from the cable itself and the surrounding environment during the process. In order to reduce the dust on the surface of the annular caliper 4 from the source, the above-mentioned cable caliper self-cleaning device also includes an exhaust pipe 3.

[0060] Among them, such as Figure 2 As shown, an exhaust pipe 3 is provided at the air outlet 1025 of each air delivery channel 102. One end of the exhaust pipe 3 is used to introduce the air discharged from the air outlet 1025, and the other end is used to blow out the introduced air. By blowing air, the cable is pre-cleaned before entering the annular caliper 4. Specifically, Figure 2 As shown, several exhaust pipes 3 are arranged in a circumferential annular array along the through hole 101, wherein one end of the exhaust pipe 3 is fixed on the end cover 1 and is connected to the air outlet 1025 at the corresponding position, and the other end extends in a spiral shape around the central axis of the through hole 101, and the extension direction is opposite to the conveying direction of the cable 5. When the air outlet 1025 outputs compressed air, the compressed air enters from one end of the exhaust pipe 3 and is blown out from the other end. During the process, the air discharged from the air transmission channel 102 can be reused for the secondary use, and the cable 5 can be pre-cleaned before entering the annular caliper 4. During pre-cleaning, the spiral-shaped exhaust pipe 3 causes the air inside it to spirally coil when discharged, and the spirally coiled gas will not be blown directly to the cable 5 when discharged from the exhaust pipe 3, but will flow around the cable 5 on the outside of the cable 5, and will not contaminate the cable 5 while pre-cleaning the cable 5.

[0061] In addition, if Figure 2 As shown, when multiple exhaust pipes 3 are arrayed, the multiple exhaust pipes 3 form a cone-shaped structure, so that the exhaust ends of the exhaust pipes 3 can be close to the cables 5, thereby improving the dust removal effect.

[0062] The method of using the self-cleaning device of a cable diameter gauge of the utility model is as follows:

[0063] Fix the end cap 1 on the annular caliper 4, pass the cable 5 through the annular caliper 4 and the through hole 101, connect the air inlet 1024 to the air source, and deliver compressed air to the air supply channel 102 through the air source. During the process, the dust suction port 1031 of the dust suction channel 103 absorbs the pollutants on the lens or the suspended pollutants around the lens to clean the lens. At the same time, the compressed air is finally discharged from the exhaust pipe 3 and blown to pre-clean the cable 5 that is about to enter the annular caliper 4.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
