Description

Technical Field

[0001] The invention relates to the technical field of cables, and in particular to a cable sheath forming device for radio frequency cable processing. Background Art

[0002] The stable phase of the cable includes mechanical stable phase and temperature stable phase. Mechanical stable phase refers to the phase change of the coaxial cable during bending and vibration. Temperature stable phase refers to the phase change of the coaxial cable during temperature changes. Whether it is mechanical stable phase or temperature stable phase, the smaller the phase change, the better, which means that the temperature and mechanical changes of a single cable are required to be kept within a certain range.

[0003] The existing amplitude-stabilized and phase-stabilized cables are mainly composed of a central conductor, a wrapped dielectric layer, an inner shielding layer, an outer shielding layer and a sheath layer. The sheath layer is extruded and coated on the outer shielding layer after high-temperature melting of the material. The outer shielding layer is mainly made of braided material with an uneven surface. Dust and impurities in the air can easily remain on the outer shielding layer. When the sheath layer is coated, the dust and impurities will affect the adhesion between the outer shielding layer and the sheath layer, affecting the production quality of the cable. Therefore, how to ensure the adhesion between the outer shielding layer and the sheath layer and improve the quality of the cable is an urgent problem to be solved by technicians in this technical field.

[0052] Compared with the prior art, the present invention has the following beneficial effects:

[0053] (1) The main and auxiliary transmission components are driven to rotate by the rotary drive mechanism, and the rotary power is transmitted to the fan component by the main and auxiliary transmission components to drive the fan component to rotate. The outer shielding layer is purged by the fan component to remove the floating dust on the outer shielding layer, so as to ensure the adhesion between the outer shielding layer and the sheath layer of the cable after coating, and ensure the production quality of the cable;

[0054] (2) One end of the cleaning block away from the coating chamber is exposed outside the blind hole and contacts the surface of the outer shielding layer. The coating chamber is driven to make a circular motion by the rotation of the first cylinder and the second cylinder. The cleaning block is driven to make a circular motion by the rotation of the coating chamber. The surface of the outer shielding layer is further cleaned by the cleaning block. Impurities that are adhered to the surface of the outer shielding layer by water or oil and cannot be cleaned by blowing are cleaned, thereby further ensuring the adhesion between the outer shielding layer and the sheath layer of the cable after coating, and ensuring the production quality of the cable;

[0055] (3) The third gear is driven to rotate by the second gear, the first stirring rod is driven to rotate by the third gear, the stirring blade is driven to rotate by the first stirring rod, and the insulating material is driven to move in the inner cavity of the heating cylinder by the rotation of the stirring blade, so that the insulating material is moved from the barrel to the second material port and enters the inner cavity of the first material port through the second material port. At the same time, during the movement of the insulating material in the inner cavity of the heating cylinder, the insulating material is turned over by the stirring blade, so that the insulating material can be heated evenly, thereby preventing some insulating materials from being heated for too long and being charred, while other parts are heated for too short a time and cannot be melted into a gel-like material;

[0056] (4) The rotation of the inner cylinder drives the connecting ring to rotate, and the rotation of the connecting ring drives the second stirring rod to make a circular motion. The second stirring rod stirs the water entering the space between the inner cylinder and the cooling outer cylinder, so that the water at different positions can contact the thermoelectric cooling plate, and the water can be evenly cooled;

[0057] (5) The inner cylinder drives the spiral blade to rotate, and the spiral blade drives the scraper to make a circular motion. The scraper is used to trim the surface of the sheath layer, and the protruding part of the surface of the sheath layer is scraped flat to ensure that the thickness of the sheath layer is uniform. The waste generated during the trimming of the sheath layer falls to the bottom of the inner cavity of the inner cylinder. The spiral blade is rotated to transport the waste by bolts, and the waste is transported to the discharge port and discharged from the discharge port, so that the waste is recycled and reused, saving costs;

[0058] (6) The external air enters the inner cavity of the air collecting port under the drive of the fan assembly, and enters the inner cavity of the inner tube through the air collecting port, driving the air flow in the inner cavity of the inner tube, and taking away the heat on the jacket layer through the air flow, thereby further improving the efficiency of cooling and solidification of the jacket layer;

[0059] (7) The surface defects of the sheath layer can be detected by using the pressure sensor and the upper and lower springs, thereby effectively ensuring the production quality of the cable. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0075] The present invention provides a cable sheath forming device for radio frequency cable processing, which drives the main and auxiliary transmission components to rotate through a rotary drive mechanism, and transmits the rotary power to the fan component through the main and auxiliary transmission components to drive the fan component to rotate. The fan component is used to blow the outer shielding layer of the cable to remove the floating dust on the outer shielding layer, which can ensure the adhesion between the outer shielding layer and the sheath layer of the cable after coating, and ensure the production quality of the cable. Please refer to Figure 1, including: a bracket assembly 100, a rotation driving mechanism 200, a fan assembly 300, a covering mechanism 400, a cooling mechanism 500 and an outer circle detection mechanism 600;

[0076] Example 1

[0077] See also Figure 1-2 , the support assembly 100 is composed of a base plate 110, a stand 120, a main transmission assembly 130 and a secondary transmission assembly 140;

[0078] The bottom plate 110 is detachably fixed to the workbench by bolts;

[0079] There are two vertical frames 120, one of which is welded to the end of the top surface of the bottom plate 110, and the other vertical frame 120 is welded to the middle of the top surface of the bottom plate 110. Both vertical frames 120 are arranged perpendicular to the bottom plate 110. The vertical frame 120 is a U-shaped vertical frame composed of two vertical plates and a horizontal plate, and the horizontal plate is fixed to the bottom plate 110.

[0080] The main transmission assembly 130 is installed between the two frames 120 through a bearing, and the number of the auxiliary transmission assemblies 140 is three. The three auxiliary transmission assemblies 140 are installed in a triangle shape between the two frames 120 through bearings. The auxiliary transmission assembly 140 and the main transmission assembly 130 are connected by a belt for power transmission. The three auxiliary transmission assemblies 140 and one main transmission assembly 130 form a rectangular transmission structure;

[0081] The rotary drive mechanism 200 is composed of a motor, a reducer and a driving gear. The motor is detachably mounted on the top surface of the base plate 110 by bolts and is arranged between the two stands 120. The reducer is detachably mounted on one end of the motor toward the output shaft by bolts. The output shaft on the motor drives the output shaft on the reducer to rotate. The driving gear is detachably mounted on the output shaft on the reducer by splines or flat keys. The output shaft on the reducer drives the driving gear to rotate. The driving gear is connected to the main transmission assembly 130 by gear meshing. The main transmission assembly 130 is driven to rotate by the driving gear. The main transmission assembly 130 transmits the rotational power to the auxiliary transmission assembly 140 to drive the auxiliary transmission assembly 140 to rotate.

[0082] There are two fan assemblies 300, which can be detachably installed between the main transmission assembly 130 and the auxiliary transmission assembly 140. The fan assembly 300 is installed on the outer side of the stand 120 through the main transmission assembly 130 and the auxiliary transmission assembly 140. The fan assembly 300 is driven to rotate by the rotation of the main transmission assembly 130 and the auxiliary transmission assembly 140. The rotation of the fan assembly 300 generates wind to sweep the surface of the outer shielding layer, remove the floating dust attached to the surface of the outer shielding layer, and prevent the floating dust from adhering to the surface of the outer shielding layer. When the cable is coated with the sheath layer, the adhesion between the outer shielding layer and the sheath layer of the cable after coating can be guaranteed, thereby ensuring the production quality of the cable.

[0083] The two ends of the covering mechanism 400 are respectively connected to the two fan assemblies 300. The covering mechanism 400 is installed in the space between the two stands 120 through the fan assemblies 300. The cable core covered with the outer shielding layer passes through the covering mechanism 400 and passes through the other end of the covering mechanism 400. The outer shielding layer covers the sheath layer in the inner cavity of the covering mechanism 400. The fan assembly 300 arranged at the inlet of the covering mechanism 400 is used to blow away the floating dust on the surface of the outer shielding layer. The fan assembly 300 arranged at the outlet of the covering mechanism 400 is used to pre-cool the outer shielding layer covered with the sheath layer, so that the sheath layer solidifies on the surface of the outer shielding layer.

[0084] The cooling mechanism 500 is detachably mounted on the upper end of the bottom plate 110 and corresponds to the fan assembly 300 at the outlet of the covering mechanism 400. The pre-cooled jacket layer penetrates into the inner cavity of the cooling mechanism 500, and the jacket layer is cooled again by the cooling mechanism 500, so that the jacket layer is completely solidified on the surface of the outer shielding layer and passes through the outlet of the cooling mechanism 500.

[0085] The outer circle detection mechanism 600 can be detachably installed in the inner cavity of the outlet end of the cooling mechanism 500 to detect the outer circle of the sheath layer after thorough solidification, detect whether there are convex or concave points on the circumferential surface of the sheath layer, and detect the thickness of the sheath layer to ensure the production quality of the cable.

One of the three auxiliary transmission wheels 140b corresponds vertically to the main transmission wheel 130c and is connected to the main transmission wheel 130c through a belt. Another auxiliary transmission wheel 140b corresponds horizontally to the main transmission wheel 130c and is connected to the main transmission wheel 130c through a belt. The last auxiliary transmission wheel 140b corresponds obliquely to the main transmission wheel 130c and is connected to the horizontally corresponding auxiliary transmission wheel 140b through a belt. The main transmission wheel 130c drives the auxiliary transmission wheel 140b to rotate through the belt, and the auxiliary transmission shaft 140a is driven to rotate through the auxiliary transmission wheel 140b.

The auxiliary drive wheels 140c are distributed on the outer sides of the two stands 120, and are driven to rotate by the auxiliary transmission shaft 140a.

[0094] The fan assembly 300 is composed of a first outer ring 310 , a first inner ring 320 and fan blades 330 .

[0095] There are two first outer rings 310, which are placed in a rectangular space formed by a main driving wheel 130d and three auxiliary driving wheels 140c.

The wind force generated by the rotation of the fan blades 330 blows the surface of the outer shielding layer to remove the floating dust on the surface of the outer shielding layer, thereby ensuring the adhesion between the outer shielding layer and the sheath layer of the cable after coating, and ensuring the production quality of the cable. The outer shielding layer covered with the sheath layer passes through the center of the first inner ring 320 arranged at the exit of the covering mechanism 400, and the first outer ring 310 driven by the main driving wheel 130d and the auxiliary driving wheel 140c to rotate drives the fan blades 330 and the first inner ring 320 to rotate. The wind force generated by the rotation of the fan blades 330 drives the flow of air around the sheath layer, thereby taking away the heat on the surface of the sheath layer, thereby achieving the purpose of pre-cooling the surface of the sheath layer.

The first outer ring 310 drives the first inner ring 320 to rotate through the fan blades 330, and drives the first cylinder 420a-1 and the second cylinder 420a-2 to rotate in the inner cavity of the outer cylinder 410 through the first inner ring 320.

[0107] The coating chamber 420c is welded in an annular shape on the inner circumferential side walls of the first cylinder 420a-1 and the second cylinder 420a-2, and a blind hole is opened on one side of the coating chamber 420c corresponding to the first cylinder 420a-1;

[0108] The cleaning block 420c-1 is embedded in the inner cavity of the blind hole, and one end of the cleaning block 420c-1 away from the coating chamber 420c is exposed outside the blind hole and contacts the surface of the outer shielding layer. The coating chamber 420c is driven to make a circular motion by the rotation of the first cylinder 420a-1 and the second cylinder 420a-2, and the cleaning block 420c-1 is driven to make a circular motion by the rotation of the coating chamber 420c. The surface of the outer shielding layer is further cleaned by the cleaning block 420c-1, and impurities that adhere to the surface of the outer shielding layer through water or oil and cannot be cleaned by blowing are cleaned, so as to further ensure the adhesion between the outer shielding layer and the sheath layer of the cable after coating, and ensure the production quality of the cable;

[0109] The discharge groove 420c-2 is opened on the side of the coating chamber 420c corresponding to the second cylinder 420a-2, and the discharge groove 420c-2 passes through the circumferential outer wall of the second cylinder 420a-2. The rubber used for the sheath layer enters the inner cavity of the outer cylinder 410 through the first material port 410a. Since the circumferential outer wall of the first cylinder 420a-1 contacts the circumferential side wall of the inner cavity of the first material port 410a, and the baffle plate 410b contacts the circumferential outer wall of the second cylinder 420a-2, the rubber entering the inner cavity of the outer cylinder 410 is blocked by the first cylinder 420a-1 and the baffle plate 410b and gathered between the second cylinder 420a-2 and the outer cylinder 410. In the space, there is a gap between the arc surface on the side of the coating bin 420c away from the second cylinder 420a-2 and the surface of the outer shielding layer. The rubber enters the inner cavity of the discharge groove 420c-2 under the obstruction of the baffle plate 410b and is discharged to the surface of the outer shielding layer through the side of the discharge groove 420c-2 away from the second cylinder 420a-2. The rubber fills the gap between the coating bin 420c and the surface of the outer shielding layer. The arc surface on the coating bin 420c contacts the surface of the outer shielding layer through the rubber. The circular motion of the coating bin 420c can evenly coat the rubber on the surface of the outer shielding layer, thereby ensuring the thickness of the sheath layer, so that the thickness of the sheath layer is consistent.

The two ends of the first stirring rod 450a respectively penetrate the side of the two end covers 440a away from the heating cylinder 440;

[0117] The stirring blade 450a-1 is welded on the outer circumferential wall of the first stirring rod 450a and is arranged in the inner cavity of the heating cylinder 440 and tangent to the inner circumferential wall of the heating cylinder 440;

The second gear 420b is driven to rotate through the first inner ring 320, and the third gear 450b is driven to rotate through the second gear 420b. The first stirring rod 450a is driven to rotate through the third gear 450b, and the stirring blade 450a-1 is driven to rotate through the first stirring rod 450a. The rotation of 50a-1 drives the insulating material to move in the inner cavity of the heating cylinder 440, and moves the insulating material from the barrel 440b to the second material port 440c and enters the inner cavity of the first material port 410a through the second material port 440c. At the same time, when the insulating material moves in the inner cavity of the heating cylinder 440, the stirring blade 450a-1 drives the insulating material to flip, so that the insulating material can be heated evenly, avoiding that some insulating material is heated for too long and becomes charred while other part is heated for too short a time and cannot be melted into a gel-like material.

The other end of the detection rod 630b is arranged adjacent to the second outer ring 610 but does not contact the second outer ring 610. A space for the detection rod 630b to be extended and retracted is reserved between the end of the detection rod 630b adjacent to the second outer ring 610 and the second outer ring 610, and the outer circumferential wall of the detection rod 630b contacts the inner wall of the split ring 630a-1.

[0148] The rolling ball 630b-1 is embedded in the end of the detection rod 630b away from the second outer ring 610, and the rolling ball 630b-1 can rotate freely on the detection rod 630b;

[0149] The lower connecting ring 630b-2 is installed on the outer circumferential wall of the detection rod 630b through a threaded connection.

The lower connecting ring 630b-2 is arranged at the lower end of the split ring 630a-1;

[0150] The upper connecting ring 630b-3 is installed on the outer circumferential wall of the detection rod 630b through a threaded connection. The upper connecting ring 630b-3 is arranged in the inner cavity of the outer sleeve 630a and connected to the outer sleeve 630a through a linear bearing. The upper connecting ring 630b-3 is arranged at the upper end of the split ring 630a-1;

[0151] The upper spring 630c is sleeved on the outer circumferential wall of the detection rod 630b and is arranged in the inner cavity of the outer sleeve 630a. One end of the upper spring 630c is detachably fixedly connected to the bottom of the upper connecting ring 630b-3, and the other end of the upper spring 630c is in contact with the top surface of the split ring 630a-1.

When there is a convex point on the sheath layer, the ball 630b-1 drives the inspection rod 630b to move upward and compress the lower spring 630d, and the value of the pressure sensor increases. When there is a pit on the sheath layer, the ball enters the pit, and the inspection rod 630b moves downward under the drive of the upper spring 630c, pulling the lower spring 630d to stretch, and the value of the pressure sensor decreases. The surface defects of the sheath layer can be detected by the coordinated use of the pressure sensor and the upper and lower springs, thereby effectively ensuring the production quality of the cable.

[0154] Example 6

[0155] The control system includes an analog-to-digital conversion module, a storage module, a processing module and a control module. The analog-to-digital conversion module is electrically connected to the particle detection mechanism 630 and is used to perform analog-to-digital conversion on the collected data. The storage module is electrically connected to the processing module and is used to perform storage of set data. The processing module is electrically connected to the analog-to-digital conversion module and is used to perform comparison between the collected data and the set data and output the comparison result. The control module is electrically connected to the processing module and is used to perform receiving the comparison result and output different control signals according to the comparison result. The control module is embedded with an audible and visual alarm and a display screen. An alarm can be sounded through the audible and visual alarm, and the alarm cause can be displayed through the display screen.

[0156] The control system includes the following specific operating steps: The control system includes the following specific operating steps:

[0157] The pressure data P0 is set by the storage module, and the pressure data collected by the pressure sensor is P1, wherein the pressure data P0 refers to the value measured by the pressure sensor when the ball 630b-1 contacts the sheath layer and drives the detection rod 630b to move upward and compress the lower spring 630d;

[0158] When P1<P0, it means that the thickness of the sheath layer is relatively thin. After power is turned on, it is very easy to break through the sheath layer and cause leakage. At this time, the control module controls the sound and light alarm to alarm, and the display screen is controlled to display the alarm reason of the thin sheath layer. The alarm sound is mainly an extremely urgent sound, and the light flashes at a very high frequency, indicating that the problem is extremely serious, which can effectively avoid the waste caused by continuous production of the production line. After receiving the alarm information, the production line workers promptly adjust the heating temperature of the inner cavity of the heating cylinder 440 to reduce the heating temperature. Because the sheath layer is too thin, it may be that the temperature of the insulating material is too high during the heating process, so that the heated gel material is too thin to effectively form a certain thickness of the sheath layer on the surface of the outer shielding layer. Therefore, by lowering the heating temperature, the gel material can be thicker. When the production is repeated after heating, the measured pressure value is still P1<P0, the production line workers need to contact the maintenance workers in time to inspect and repair the equipment. When the production is repeated after heating, the measured pressure value P1>P0, follow the steps below;

[0159] When P0<P1<1.125×P0, it means the thickness of the sheath layer is just right, and production can continue without any treatment;

[0160] When 1.125×P0<P1<1.140×P0, it means that the thickness of the sheath layer is thicker, but it does not affect the overall quality of the cable. The control module controls the sound and light alarm to sound an alarm, and the alarm sound and alarm light sound an alarm at a frequency of 5-7 minutes. The production line workers can reduce the thickness of the sheath layer by increasing the temperature of the inner cavity of the heating cylinder 440 to make the gelatinous material thinner. When the sound and light alarm no longer sounds within 10-15 minutes after the production line workers increase the temperature of the inner cavity of the heating cylinder 440, the heating cylinder 440 continues to increase the temperature. During production, when the sound and light alarm still sounds within 10-15 minutes after the temperature of the inner cavity of the heating cylinder 440 is increased, the production line worker checks the scraper 520c-1 to see if the scraper 520c-1 is worn. If the scraper 520c-1 is worn, the production line worker manually turns off the sound and light alarm and replaces the scraper 520c-1 after one shift. If the scraper 520c-1 is not worn, the production line worker notifies the maintenance worker to inspect and repair the equipment, thereby ensuring product quality while ensuring the production quantity of the production line, and achieving the goal of good and fast production.

[0161] When 1.140×P0<P1, it means that the thickness of the sheath layer is extremely thick, which will affect the quality of the final product. Because the sheath layer is too thick, the overall weight of the final product will increase, and it will also affect the bending effect of the finished cable. At this time, the control module controls the sound and light alarm to sound an alarm, and the alarm sound and alarm light sound an alarm at a frequency of 3-5 seconds. The production line workers check the scraper 520c-1 to see if there is wear on the scraper 520c-1. When the scraper 520c-1 is worn, the line is immediately stopped to replace the scraper 520c-1. The cables that have been coated with the sheath layer are marked and isolated as defective products for storage. After the scraper 520c-1 is replaced, if the measured pressure data is still 1.140×P0<P1, the production line workers notify the maintenance workers to inspect and repair the equipment.

[0162] Based on the above pressure data, the control module is also embedded with a timing module, and the time data T is set through the storage module, and the unit of T is minutes;

[0163] When 10<T<60, the value of P1<P0 appears every 5-7 minutes, and when P1>0.895×P0, the value of P1<P0 does not appear more than 5 times, the produced cable is a qualified product, and no treatment is done, and production continues;

[0164] When 10<T<60, the value of P1<P0 appears every 3-5 minutes, and when P1>0.895×P0, the value of P1<P0 appears 5-9 times, and the control module controls the sound and light alarm to sound an alarm. After receiving the alarm, the production line workers should immediately stop the line and contact the maintenance workers for inspection and maintenance. At the same time, the produced cables should be marked and isolated and sent to the unqualified processing station for recycling;

[0165] When T<10 and P1<P0, the above step shall be followed regardless of whether the pressure value of P1<P0 appears at the time interval or not;

[0166] When 1<T<60 and P0<P1<1.125×P0, all products are treated as qualified products;

[0167] When 1<T<60, the value of 1.125×P0<P1<1.140×P0 appears every 5-7 minutes. If the value of 1.125×P0<P1<1.140×P0 does not exceed 5 times, it will be treated as a qualified product. When the value of 1.125×P0<P1<1.140×P0 appears every 3-5 minutes, it means that there are convex spots on the surface of the sheath layer, but it does not affect the quality of the final product. At this time, the control module controls the sound and light alarm to alarm, and the production line After receiving the alarm, the worker first checks the scraper 520c-1. If there is a gap in the scraper 520c-1, the scraper 520c-1 will be replaced after one shift. If there is no gap in the scraper 520c-1, the production line worker needs to check the cables that are not covered with the sheath layer to see if there are bumps on the outer shielding layer. If there are bumps on the outer shielding layer, the warehouse will be contacted in time to conduct a full inspection and isolation of the batch of cables that are not covered with the sheath layer. However, the production on the production line will still be carried out to ensure the normal operation of the production line and the production quantity.

[0168] When 1<T<60, the value of 1.140×P0<P1 appears every 5-7 minutes. If the value of 1.140×P0<P1 does not appear more than 5 times, it means that there are convex spots on the surface of the sheath layer and the convex spots are large. When the frequency of occurrence is not high, it does not affect the quality of the final product. At this time, the control module controls the sound and light alarm to sound an alarm. After receiving the alarm, the production line workers first check the scraper 520c-1. If there is a gap in the scraper 520c-1, the scraper 520c-1 is replaced after one shift. If there is no gap on the scraper 520c-1, the production line workers need to check the cables that are not covered with the sheath layer. Check whether there are any convex points on the outer shielding layer. If there are convex points on the outer shielding layer, contact the warehouse in time to conduct a full inspection and isolation of the batch of cables that are not covered with the sheath layer. However, the cables on the production line are still produced to ensure the normal operation of the production line and the production quantity. When the value of 1.140×P0<P1 appears more than 5 times, the sound and light alarm will be used to alarm. When the production line workers receive the alarm information, they will stop the line immediately, mark and isolate the existing cables on the production line that have not been covered with the sheath layer, and contact the warehouse to mark and isolate the cables that are not covered with the sheath layer, and then transport another batch of cables that are not covered with the sheath layer to the production line for production to ensure the normal operation of the production line.
