Detailed implementation manners

[0028] The following further describes the present invention with reference to the accompanying drawings. This description is only used to explain the detailed implementation manners of the present invention and cannot be understood in any form as a limitation to the present invention. The detailed implementation manners are as follows:

[0029] As Figure 1 shown and referring to Figure 2, A marine cable bundling machine includes an integrally formed bundling machine body 11, a holding part 2, and a fixed guiding part 14. The fixed guiding part 14 includes a guiding groove 13, which is arranged at the side end of the bundling machine body 1. The guiding groove 13 is adapted to the thickness of the steel strapping used for bundling, so that the steel strapping for bundling can just pass through the guiding groove 13 unobstructed. The bundling machine body 11 includes a cylindrical cavity. The twisting shaft 16 is rotatably arranged in the cylindrical cavity of the bundling machine body 11 and includes a first twisting shaft 1601 and a second twisting shaft 1602 with collinear axial centers. A rotating groove 7 is arranged at one end of the second twisting shaft 1602, which has the same groove depth and groove width as the guiding groove 13 and is on the same side of the bundling machine body 11 as the guiding groove 13. The other end of the second twisting shaft 1602 has a threaded hole. One end of the first twisting shaft 1601 has a stud adapted to the threaded hole of the second twisting shaft 1602, and the first twisting shaft 1601 is connected to the second twisting shaft 1602 through the stud and the threaded hole. The connecting wheel 8 is a "windmill type" toothed ratchet structure and is fixed on the second twisting shaft 1602. The sounding wheel 10 has an outer diameter adapted to the cylindrical cavity of the bundling machine body 11 and is placed in the cavity. The sounding wheel 10 has a cylindrical accommodating cavity inside. The outer diameter of the connecting wheel 8 is adapted to the accommodating cavity of the sounding wheel 10 and is placed in the accommodating cavity. The connecting wheel 8 can rotate unidirectionally relative to the sounding wheel 10. The sounding wheel 10 is preferably made of hard metal, and a number of sounding grooves 101 are arranged circumferentially thereon. The holding part 2 has an adjustment cavity radially communicating with the cylindrical cavity of the bundling machine body 11. The clamping part 5 is preferably made of hard metal or ceramic, and its maximum outer diameter is adapted to the adjustment cavity of the holding part 2 and is placed in the adjustment cavity, so that the clamping part 5 can slide in the adjustment cavity. The elastic member 4 and the torque adjustment member 3 are arranged in the adjustment cavity of the holding part 2. One end of the clamping part 5 is elastically connected to the torque adjustment member 3 through the elastic member 4, and the other end is clamped in the sounding groove 101. When the sounding wheel 10 rotates, the clamping part 5 can enter from one sounding groove 101 into an adjacent another sounding groove 101, and at the same time, under the elastic force of the elastic member 4, it can strike the sounding groove 101 to make a sound. The torque adjustment member 3 is threadedly connected to the holding part 2. The distal end of the torque adjustment member 3 connected to the elastic member 4 is fixedly connected to the knob 1. By rotating the knob 1, the distance between the connecting end of the torque adjustment member 3 and the elastic member 4 and the clamping part 5 can be changed, thereby controlling the rotation torque of the sounding wheel 10.

[0030] The shearing shaft 12 is rotatably fixed on the bundling machine body 1. One axial end of the shearing shaft 12 has a shearing groove with a "one" - shaped opening, and the other end is fixedly connected to the shearing rod 15. The groove depth and groove width of the shearing groove are both the same as those of the guiding groove 13. On the rotation path of the shearing shaft 12, the shearing groove can coincide with the guiding groove 13 so that the steel strapping can pass through both at the same time. Through the rotation of the shearing shaft 12, a shearing force can be generated at the contact position between the shearing groove and the guiding groove 13 to cut the steel strapping.

[0031] In some embodiments, a marine cable baler further includes a torque identifier 18 disposed outside the holding portion 2. The preset torque of the marine cable baler can be read through the torque identifier 18, facilitating torque adjustment.

[0032] As Figure 3 shown and referring to Figure 1 , the inner cavity wall of the accommodating cavity of the sound - generating wheel 10 includes a plurality of limiting grooves 101. The dimension of the connection between the limiting groove 101 and the opening of the inner cavity wall of the accommodating cavity is smaller than the dimension of the limiting groove 101. The limiting body includes a limiting rod 63 and a limiting head 62 disposed at its end. The dimension of the limiting groove 101 is adapted to the dimension of the limiting head 62, and the dimension of the connection between the limiting groove 101 and the opening of the inner cavity wall of the accommodating cavity is adapted to the dimension of the limiting rod 63, so that the limiting body can slide in the limiting groove 101 and cannot be separated from the limiting groove 101. A limiting spring 61 is disposed between the limiting groove 101 and the limiting head 62, which can make the limiting rod 63 protrude from the inner cavity wall of the accommodating cavity of the sound - generating wheel 10. The length of the limiting body is smaller than the depth of the limiting groove 101, so that when the limiting body is subjected to an external force, it can completely enter the limiting groove 101. When the connecting wheel 8 rotates clockwise, it presses the limiting body into the limiting groove 101 by relying on the "windmill - type" toothed ratchet structure. When rotating counter - clockwise, due to the limiting effect of the limiting body, the connecting wheel 8 can rotate synchronously with the sound - generating wheel 10.

[0033] As Figure 4 shown and referring to Figure 2 , in some embodiments, the locking ratchet 19 is fixed on the first twisting shaft 1601. The pawl 20 is disposed on the locking rod 17 rotatably connected to the first twisting shaft 1601. By swinging the locking rod 17, the connecting wheel 8 can rotate in the same direction as the locking ratchet 19, which can improve the convenience of the rotation of the twisting shaft 16.

[0034] Working principle of the present invention: Driven by the locking rod 17 to rotate, the first torsion shaft 1601 and the second torsion shaft 1602 are fastened. The rotating groove 7 rotates synchronously with the torsion shaft 16. The steel cable tie inserted into the rotating groove 7 winds and tightens under the action of rotation for cable fixing. At this time, the connecting wheel 8 rotates clockwise with the torsion shaft 16. The connecting limiting member 6 is pressed by the "windmill-type" toothed ratchet structure, and the limiting rod 63 enters the limiting groove 101, and the sound-generating wheel 10 and the connecting wheel 8 rotate relatively. After reaching the rated torque, under the reaction force of the cable tie, the connecting wheel 8 fixed on the second torsion shaft 1602 rotates in the reverse direction. Due to the limiting effect of the connecting limiting member 6, at the same time, the first torsion shaft 1601 and the second torsion shaft 1602 are loosened, so that the sound-generating wheel 10 and the connecting wheel 8 rotate synchronously. Furthermore, the clamping member 5 enters from the original sound-generating groove 9 in the circumferential direction of the sound-generating wheel 10 into the adjacent sound-generating groove 9, and makes a knocking sound with the sound-generating wheel 10 under the elastic force of the elastic member 4 to remind the operator that the rated torque is reached. At this time, using a tool to lock the buckle can fix the cable tie with a constant torque.

[0035] All components of a marine cable tying machine are closely connected to form a complete whole, so as to stop tightening the cable tie and make a clicking sound after reaching the rated torque, effectively preventing the problems of over-looseness or over-tightness of the cable caused by manual operation. All components together constitute the technical solution of the present invention and cannot be separated individually. The superposition of individual components with similar functions cannot solve the corresponding technical problems of the present invention.

[0036] At this point, those skilled in the art should recognize that although the exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and determined to cover all these other variations or modifications.
