DETAILED DESCRIPTION

[0021] The scheme proposed in the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the drawings are in a very simplified form and use non-precise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the implementation methods of the present invention.

[0022] Figure 1 A schematic diagram of a manufacturing device for a medical cable provided by the present invention is shown. Figure 2 The schematic diagram of the cable structure is shown in FIG. Figure 1-Figure 2 As shown, the manufacturing device of the medical cable is used to manufacture the cable, the cable comprising a core 201 and an outer layer 202 wrapped around the outer periphery of the core 201, the outer layer 202 being wrapped around the outer periphery of the core 201 in a braided manner, the outer layer 202 comprising a tight portion 210 and a sparse portion 220 periodically arranged along the extending direction of the core 201; Figure 2 It can be seen that there is a gap between the sparse portion 220 and the core 201. Therefore, when the cable is bent, the problem of the outer layer 202 and the core 201 being easily broken due to multiple bends due to the close fit between them is solved, and the problem of the braided outer layer 202 being easily broken due to mutual stretching and squeezing is avoided. In addition, the gap between the tight portion 210 and the core 201 is very small or non-existent. This has the advantage of providing a certain degree of support between the core 201 and the outer layer 202, preventing the cable from being too loose. Therefore, the periodic arrangement of the tight portion 210 and the sparse portion 220 is conducive to extending the life of the cable.

[0023] In order to form the tight portion 210 and the sparse portion 220 in the outer layer 202, the present invention provides a manufacturing device for a medical cable, such as Figure 1 As shown, it includes: a base 110, an outer layer wire conveying member 102, a lifting device, a roller 106 and a tightening forming member 130.

[0024] The roller 106 is positioned directly above the horizontal base 110, supported by legs. A hole (not shown) is provided in the center of the base 110. The cable core 201 passes vertically through the hole in the center of the base 110, with the roller 106 providing power for cable transport, allowing for upward transmission. The lower roller 104 is positioned directly below the base. The cable core 201 is pulled upward by the roller 106, guided from below by the lower roller 104, allowing for upward transmission.

[0025] The outer layer wire conveyor 102 is rotatably mounted above the base 110 and is used to convey the outer layer wire to the outside of the wire core 201, thereby weaving the outer layer 202 around the outer layer 201. Specifically, the outer layer wire conveyor 102 is annular, with multiple wire conveyor rollers 103 evenly spaced on its upper surface for conveying the plurality of outer layer wires. A circular opening is provided at the center of the annular outer layer wire conveyor 102.

[0026] The lifting device is disposed above the base 110 and surrounds the hole of the base 110 .

[0027] The tensioning member 130 is connected to the lifting device and is also located above the base 110. The tensioning member 130 is partially positioned between the core 201 and the outer layer 202. The lifting device periodically drives the tensioning member 130 up and down, controlling the size of the gap between the core 201 and the braided layer by raising and lowering the tensioning member 130, thereby forming a tight portion 210 and a loose portion 220 in the outer layer 202. Specifically, the lifting device and the tensioning member 130 are located in the circular opening at the center of the outer layer wire conveying member 102 and extend through the circular opening. The circular opening is much larger than the hole in the base 110.

[0028] The manufacturing device further includes a sizing member 120 and a bracket 140. The sizing member 120 and the roller 106 are both connected and fixed to the base 110 via the bracket 140. The sizing member 120 is arranged directly above the tension forming member 130 and directly below the roller 106. The cable vertically passes through the sizing hole 123 of the sizing member 120. The outer layer wire forms an outer layer area S (such as Figure 9 As shown) wrapping the wire core 201 to form the outer layer 202.

[0029] Figure 6 Shows a schematic diagram of the structure of the sizing piece, such as Figure 6As shown, the sizing member 120 includes a cylindrical body, a positioning ring 122 and a lip 121. The positioning ring 122 is arranged above the outer circumference of the cylindrical body. The center of the cylindrical body is provided with a sizing hole 123 which passes through vertically up and down. An annular lip 121 is arranged around the sizing hole 123. The outer layer wire wraps the wire core 201 in the outer layer forming area S below the sizing hole 123 to form the outer layer 202. The manufactured cable is conveyed vertically upward through the sizing hole 123. When the outer layer wire is woven in the outer layer forming area S, since the outer layer wire forms a large angle with respect to the vertical, the lip 121 can well protect the outer layer wire gathered here to avoid being cut. The bracket 140 includes a sizing member 120 fixing plate and a locking screw 141. The sizing member 120 fixing plate is horizontally arranged and is provided with a vertical T-shaped through hole. The inner contour of the T-shaped through hole is adapted to the outer contour of the sizing member 120. The sizing member 120 is arranged in the T-shaped through hole. The locking screw 141 is threadedly screwed from the side of the sizing member 120 fixing plate to the T-shaped through hole to fix the sizing member 120.

[0030] Figure 3 Shown is a schematic diagram of the structure of the tightening forming member, as shown in Figure 3 As shown, the tightening member 130 includes a base 131, a limiting ring 132, and a baffle 134. The limiting ring 132 is disposed above the base 131, and the baffle 134 is disposed above the limiting ring 132. The baffle 134 is configured to at least partially and periodically insert between the wire core 201 and the outer layer 202 to adjust the gap between the wire core 201 and the outer layer 202. The base 131 is generally in the form of an oblate cylinder with an inverted concave cross-section. The limiting ring 132 is annular in shape. The limiting ring 132 and the base 131 are connected and concentric. The wire core 201 first passes through the base 131 and then through the limiting ring 132. The through hole in the middle of the limiting ring 132 is used to constrain the passing wire core 201. Preferably, the diameter of the base 131 is larger than the diameter of the limiting ring 132.

[0031] Preferably, the tightening forming member 130 further includes a fan-shaped slope 133, which is arranged between the limiting ring 132 and the baffle 134, and is inclined toward the wire core 201. The fan-shaped slope 133 is used to prevent the outer layer wire from getting stuck and to prevent the outer layer wire from being cut.

[0032] The baffle 134 is a long strip plate extending vertically, and its width direction is arc-shaped, and the arc is adapted to the outer wall of the wire core 201 to prevent the outer layer wire from being cut; the inner surface of the long strip plate close to the wire core 201 is parallel to the outer wall of the wire core 201; preferably, the arc in the width direction only surrounds less than 1 / 3 of the circumference of the wire core 201 in the circumferential direction; the baffle 134 includes an upper section 1341 and a lower section 1343, and the upper section 1341 is arranged above the lower section 1343, and the top surface of the upper section 1341 is arc-shaped, so that the baffle 134 can move between the wire core 201 and the outer layer 202 without cutting the outer layer wire.

[0033] In some embodiments, the thickness of the upper section 1341 and the lower section 1343 of the baffle 134 are equal. Figure 3 In this embodiment, the baffle 134 is configured to at least partially and periodically be inserted between the core 201 and the outer layer 202 to adjust the gap between the core 201 and the outer layer. Specifically, during the formation of the sparse portion 220, the lifting device drives the sparse forming member 130 to move upward as a whole, and the baffle 134 is inserted between the core 201 and the outer layer 202. The top end of the upper section 1341 of the baffle 134 passes upward through the sizing hole 123 of the sizing member 120 until it exceeds the upper surface of the sizing member 120. During this stage, due to the action of the baffle 134, a larger gap is formed between the core 201 and the outer layer 202, ultimately forming the sparse portion 220.

[0034] Subsequently, the lifting device drives the tension forming member 130 to move downward as a whole. When the top surface of the upper section 1341 of the baffle 134 moves downward to below the outer layer forming area S, the tight portion 210 formation stage begins. In this stage, since the baffle 134 is not between the core 201 and the outer layer 202, there is no gap between the core 201 and the outer layer 202, and finally the tight portion 210 is formed. By repeating the above two stages, a periodic tight portion 210 and loose portion 220 can be formed on the outer layer.

[0035] Figure 7-Figure 9 Shown is another embodiment of a tension forming member, such as Figure 7-Figure 9 As shown, optionally, the outer surface thickness of the upper section 1341 of the baffle of the tensioning member 130 is less than the outer surface thickness of the lower section 1343. The baffle 134 further includes a transition section 1342, which is disposed between the upper section 1341 and the lower section 1343. The transition section 1342 is a slope extending from the lower section 1343 toward the upper section 1341. That is, the outer surface of the baffle 134 near the wire core 201 is stepped.

[0036] In this embodiment, during the formation of the sparse portion 220 (eg Figure 9As shown), the lifting device drives the tensioning forming member 130 to move upward as a whole, and the baffle 134 is inserted between the wire core 201 and the outer layer 202. The top end of the upper section 1341 of the baffle 134 passes upward through the sizing hole 123 of the sizing member 120 until it exceeds the upper surface of the sizing member 120. At this stage, the lower section 1343 of the baffle 134 is always in the outer layer forming area S, so that there is a large gap between the wire core 201 and the outer layer 202, and finally the sparse portion 220 is formed. Subsequently, the lifting device drives the tensioning forming member 130 to move downward as a whole. When the upper section 1341 of the baffle 134 enters the outer layer forming area S, the tight portion 210 is formed (as shown). Figure 8 (As shown in the figure), during this stage, the upper section 1341 of the baffle 134 remains in the outer layer forming area S, and the top surface of the upper section 1341 remains between the wire core 201 and the outer layer 202. Due to the relatively thin thickness of the upper section 1341 of the baffle 134, the gap between the wire core 201 and the outer layer 202 is very small, ultimately forming a tight portion 210. Repeating these two stages, a periodic pattern of tight portions 210 and sparse portions 220 is formed in the outer layer. In this embodiment, a portion of the baffle 134 always remains between the wire core 201 and the outer layer 202. Compared to the previous embodiment, this prevents the baffle 134 from moving up and down and severing the outer layer wire.

[0037] Figure 4-Figure 5 Shows a schematic diagram of the structure of the tightening forming member and the lifting device, as shown in Figure 4-Figure 5 The lifting device includes a fixed ring 111, an elastic member 115 and a rotating member 113; the fixed ring 111 is arranged above the base 110 and is arranged around the hole of the base 110, and the base 131 of the tightening forming member 130 is arranged in the ring of the fixed ring 111; preferably, the diameter of the base 131 is slightly larger than the diameter of the hole of the base 110, and the diameter of the hole of the base 110 is slightly larger than the diameter of the wire core 201, so that the wire core 201 can pass through. The elastic member 115 is arranged between the base 110 and the base 131, and the elastic member 115 is configured to provide an upward force to the base 131. The rotating member 113 is used to drive the base 131 to periodically move downward relative to the fixed ring 111.

[0038] Optionally, the base 131 is concave in shape, and a vertically extending rack 138 is provided on the outer side of the concave side wall. The rotating member 113 includes an incomplete gear 114 and a driving member for driving it to rotate. The incomplete gear 114 cooperates with the rack 138 to drive the base 131 to move downward periodically relative to the fixed ring 111.

[0039] The elastic member 115 is a spring, and an annular vertical plate 135 is provided inside the concave side wall, so that an annular groove 136 with a downward opening is provided on the inner side of the concave side wall. The upper end of the spring is provided in the annular groove 136, and the lower end of the spring is provided on the upper surface of the base 110.

[0040] Preferably, the fixed ring 111 is a C-shaped ring, and the rotating member 113 is disposed at the notch of the C-shaped ring. The lifting device further includes a guide device comprising a strip groove 112 and a mating protrusion 137. The strip groove 112 is disposed on the inner side of the side wall of the C-shaped ring and extends vertically; the protrusion 137 is disposed on the outer side of the concave side wall.

[0041] by Figure 4 As shown in the example, when the rotating member 113 rotates counterclockwise, the toothed portion of the incomplete gear 114 engages with the rack 138, driving the base 131 downward. When the toothless portion of the incomplete gear 114 rotates to the position of the rack 138, the base 131 cannot move further downward due to the lack of the toothed portion. At this point, the upward force of the spring drives the base 131 upward. Due to the presence of the guide device, the base 131 is limited to movement in a fixed position. Depending on the ratio of the toothed and toothless portions of the incomplete gear 114 and the rotation speed of the rotating member 113, the lifting and lowering time can be adjusted, thereby adjusting the formation time of the tight portion 210 and the loose portion 220.
