Traditional 2M coaxial cable need carry out wire stripping, crimping and welding operation in proper order at manual preparation process, and work load is big, the process is loaded down with trivial details, the qualification rate is low, the uncontrollable problem of preparation quality unstability, leads to that operating time is long, work efficiency is low in newly-built construction and daily operation maintenance. When the cable joint welds, need manual solder wire to send to flatiron heating point, make the solder wire melt at the heating point and weld, the communication channel that causes because of rosin joint scheduling problem unusual trouble also influences the safety and stability operation of electric wire netting. After the cable joint is automatically manufactured, the cost of manpower and material resources is greatly reduced, and the manufacturing efficiency is improved. When the cable joint is welded, the automatic welding device is provided with the tin conveying mechanism, for example, the tin wire is clamped and conveyed through the two mutually-matched rollers, so that the directional conveying of the tin wire is realized. The in-process that the solder wire was giving, if the device breaks down, the unable forward movement that lasts of tin wire that front end and flatiron contacted, then the tin wire can appear blockking up the problem. If no staff is on site to watch in real time, and the emergency measures cannot be found and taken in time, the tin wire is easily damaged due to blockage, and even equipment failure occurs.

In conclusion, the invention provides an anti-blocking accessory for an automatic tin feeding mechanism, which is arranged on the existing automatic tin feeding mechanism and is used for automatically monitoring whether a tin wire is blocked or not, and sending an alarm signal when the tin wire is detected to be blocked so that a worker can timely respond. The working principle of the invention is as follows: when the tin silk front end blockked up, because interior sheathed tube internal diameter is far away than the external diameter of tin silk, consequently the tin silk is at first piled up at interior endotheca intraductally, the tin silk that piles up gradually contacts with the driving plate in interior sleeve to produce the extrusion effect to the driving plate, the elastomer is compressed, drive conducting strip I on the driving plate and move forward along the inner skleeve axial, until electrode slice I and conducting strip II coincidence contact electrically conduct, series circuit switches on, alarm module sends alarm signal, after the staff received alarm signal, made corresponding treatment. When the blockage is cancelled, the accumulated tin wires in the inner sleeve are moved away, the extrusion effect on the transmission plate is eliminated, the transmission plate and the conducting strips I on the transmission plate are driven to move reversely to reset under the self elastic recovery effect of the elastic body until the power failure caused by the staggering of the electrode plates I and the conducting strips II, the power failure of the series circuit is caused, and the alarm module is in contact with the alarm module to alarm.

Furthermore, the conducting strips I are annular strip structures which are continuously distributed along the circumferential direction of the outer wall of the transmission plate; the conducting strip II is an annular strip structure which is continuously distributed along the circumferential direction of the inner wall of the inner sleeve.

Through all setting up conducting strip I and conducting strip II and circularizing the structure, do benefit to the guarantee when taking place to block up, conducting strip I and conducting strip II can normally contact, also do benefit to the detection precision. Especially when the accumulational tin silk extrusion driving plate in the inner sleeve, because the driving plate atress is uneven, can take place the slope, because conducting strip I and conducting strip II all set up annular structure, even if under the circumstances of driving plate inclined movement, conducting strip I of driving plate slope side outer wall also can be smoothly with conducting strip 2 contact.

Furthermore, the outer wall of the conducting plate I protrudes outwards to form an arc surface, and the radial section of any section of the annular structure of the conducting plate I is of a D-shaped structure; and the conducting strip I is contacted with the point blade II through the arc-shaped surface.

Be the arcwall face with conducting strip I's outer wall evagination, guarantee conducting strip I outer wall and conducting strip II inner wall smooth contact, prevent that the driving plate from receiving to pile up tin silk extrusion force inhomogeneous, cause the driving plate card shell to be difficult to the phenomenon that resets.

Further, in the compression direction of the elastic body, the inner diameter of the conducting strip II is gradually reduced, and the inner diameter of the axial middle part of the conducting strip I is equal to the outer diameter of the conducting strip I; any section of the annular structure of the conducting strip II has a wedge-shaped radial section.

The conducting strip II is arranged to be of a reducing structure, so that the conducting strip II is beneficial to being suitable for conducting strips with different outer diameters on one hand; on the other hand plays the effect of spacing, protection elastomer (especially the elastomer adopts the spring), as long as ensure conducting strip I and conducting strip II contact when piling up tin silk pressurization driving plate can, through conducting strip I and driving plate card can in the middle part of conducting strip II, prevent that the elastomer excessively compresses, or inhomogeneous local compression deformation from damaging.

Furthermore, the elastic body adopts a plurality of columnar compression springs which are distributed in a ring shape by taking the axial lead of the transmission plate as the center.

The elastomer adopts a plurality of independent compression springs, and especially when the tin silk is inhomogeneous to extrude the driving plate, each spring independent work effectively avoids the elastomer to damage the problem.

Furthermore, one end of the inner sleeve extends into the outer sleeve for adaptation, the other end port of the inner sleeve is closed, and a wire outlet for the silk thread to pass through is formed in the closed end face.

Through sealing the other end port with the inner skleeve, make the inside closed chamber who holds and pile up the tin silk that forms of inner skleeve, restricted the orientation of piling up of tin silk, after the resistance reaches a definite value is piled up to tin silk in the inner skleeve, the tin silk can begin again to pile up outside the inner skleeve, nevertheless can ensure to have accumulational tin silk extrusion driving plate in the inner skleeve all the time through the blind end, the guarantee lasts, effectively reports to the police. The closed end of the inner sleeve may be a removable apertured cover plate.

Furthermore, the inner wall of the wire outlet protrudes to form an arc-shaped surface, and the inner wall of the wire outlet is in smooth contact with the tin wire through the arc-shaped surface.

Under the condition of blockage, the tin wire is bent due to the fact that the tin wire is accumulated in the inner sleeve, the line section of the tin wire located in the inner sleeve and the line section of the tin wire located outside the inner sleeve are bent at the wire outlet to form a certain angle, the wire outlet can extrude the tin wire, and if the wire outlet is provided with an edge, the tin wire is prone to being damaged. The invention sets the wire outlet of the closed end surface of the inner sleeve to be in a cambered surface structure, ensures the smooth contact between the inner wall of the wire outlet and the tin wire and prevents the tin wire from being damaged. In addition, when the blockage is removed, the tin wire accumulated in the inner sleeve needs to be pulled out, and the bent tin wire in the inner sleeve is always straightened through a smooth wire outlet with a cambered surface.

Furthermore, the inner sleeve extends into the outer sleeve from an axial port of the outer sleeve, and the outer wall of the inner sleeve is in threaded connection with the inner wall of the inner sleeve; the other end of the outer sleeve is connected with the end part of the conveying pipe in a threaded connection sleeve mode.
