DETAILED DESCRIPTION

[0032] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Example 1

[0034] Figure 1 The invention shows a three-dimensional structure diagram of a cable outer protective film winding processing device, which includes a vertically arranged horizontal plate and a vertical plate, and a first extrusion mechanism 5 installed on the horizontal plate, a film winding mechanism 2, and a second extrusion mechanism 3 installed on the vertical plate. Figure 2 As shown, the film winding mechanism 2 includes a hollow rotating platform 21 and a rotating disk 22. For details, please refer to Figure 2 The hollow rotating platform 21 is installed on the vertical plate through the motor frame 211. The hollow rotating platform 21 is a hollow structure. The driving motor is connected to the side to facilitate the installation of air pipes and wires in the mold. Preferably, the hollow rotating platform 21 adopts the SR side-axis type ZCT62-1 / 18. The rotating disk 22 is installed on the rotating ring of the hollow rotating platform 21 and rotates therewith. The rotating disk 22 is provided with a plurality of film placing tubes 23 along its circumference, and one end of each film placing tube 23 is connected and communicated with a film cavity 24. In the present embodiment, there are four groups of membrane cavities 24 and film placing tubes 23. Specifically, there is no film roll in the film placing tube 23. One end of the film roll extends out along the channel connecting the membrane cavity 24 and the film placing tube 23 and is wound around the cable core. The cable core passes through the center of the hollow rotating platform 21 and passes through the first extrusion mechanism 5 and the second extrusion mechanism 3. When the hollow rotating platform 21 rotates, the film is driven to be wound. It is particularly important to note that a damping structure is provided between the film roll and the membrane cavity 24, and a certain pulling force is required to make the film roll rotate. At the same time, the first extrusion mechanism 5 and the second extrusion mechanism 3 squeeze and tighten the wound film. Figure 3-4 As shown, the first extrusion mechanism 5 includes an annular frame 51 fixed to the horizontal plate, and a plurality of extrusion components 52 uniformly distributed along the inner circumference of the annular frame 51, and the extension lines of the plurality of extrusion components 52 are concentrated at one point, which is located on the center line of the annular frame 51. The annular frame 51 is trumpet-shaped. Specifically, in this embodiment, the annular frame 51 is a trumpet-shaped hollow hexagonal pyramid, wherein the opening end with a larger radius faces the film winding mechanism 2. In this embodiment, four extrusion components 52 are provided. Specifically, the extrusion component 52 includes a sleeve 521, a shaft support 523 and a pressing wheel 5 24, the sleeve 521 is tiltedly arranged on the inner side wall of the annular frame 51, and the angle between the sleeve 521 and the annular frame 51 is 30° to 60°. Preferably, the angle between the sleeve 521 and the annular frame 51 is set to 30°. One end of the shaft support 523 is provided with a slide groove that matches the diameter of the sleeve 521. The sleeve 521 is slidably connected with the slide groove. A spring 522 is arranged between the sleeve 521 and the shaft support 523. A pressure wheel 524 is arranged at the other end of the shaft support 523. The outer ring of the pressure wheel 524 is conical, and the pressure wheel 524 can be removed and replaced. Figure 5As shown, the second extrusion mechanism 3 includes two rollers relatively arranged on the vertical plate. The two rollers are respectively an active roller 31 and a driven roller 36. The active roller 31 is rotatably arranged on the vertical plate, and the active roller 31 is transmission-connected to the servo motor 32. The driven roller 36 is rotatably arranged on the displacement mechanism. The displacement mechanism includes a first slide rail 33 fixedly arranged on the vertical plate, a first slider 34 slidingly matched with the first slide rail 33, a vertical support plate 35 fixedly installed on the first slider 34, and a first cylinder 37 fixedly arranged on the vertical plate. The piston rod of the first cylinder 37 is fixedly connected to the vertical support plate 35, and the driven roller 36 is rotatably connected to the vertical support plate 35. A transverse pressure plate 38 is arranged between the active pressure roller 31 and the passive pressure roller 36, one end of the transverse pressure plate 38 is fixed on the vertical plate, a threading channel is provided on the upper side of the transverse pressure plate 38 along the length direction, and a trapezoidal notch is provided in the middle of the transverse pressure plate 38; the trapezoidal notch is just located between the active pressure roller 31 and the passive pressure roller 36, and the trapezoidal notch is connected to the threading channel. When the servo motor 32 is started, the servo motor 32 drives the active pressure roller 31 to rotate, and then operates the first cylinder 37, and the first cylinder 37 drives the vertical support plate 35 to move downward. After the passive pressure roller 36 contacts the active pressure roller 31, the downward movement of the first cylinder 37 is stopped. At this time, the cable core after winding the film is squeezed between the active pressure roller 31 and the passive pressure roller 36. As the active pressure roller 31 rotates, the cable core is driven forward by friction and is squeezed and tightened again.

[0035] It should be noted that the upper end of the threading channel is open, and a cover plate 39 is arranged above the opening, and one end of the cover plate 39 close to the trapezoidal notch is chamfered. A detachable cover plate 39 is arranged to facilitate the removal of the cable core.

[0036] Example 2

[0037] This embodiment is basically the same as embodiment 1, except that

[0038] like Figure 5 and Figure 7As shown, the shearing mechanism 4 is also included, and the shearing mechanism 4 includes a scissor support plate 41, a cutter 44 slidably connected to the scissor support plate 41, and a second cylinder 43 fixedly connected to the cutter 44. Specifically, the scissor support plate 41 is fixedly installed on the vertical plate, and two cutters 44 are symmetrically arranged and slidably connected to the scissor support plate 41. Specifically, the scissor support plate 41 has a channel allowing the cutter 44 to slide, and the channel is vertically arranged. The second cylinder 43 is connected to the cutter 44 through a guide plate 42, wherein the guide plate 42 is slidably connected to the scissor support plate 41, and the sliding direction is along the horizontal direction. The guide plate 42 is provided with an inclined guide slideway, and the guide slide A pin 45 is provided in the guide channel, the pin 45 is fixedly connected to the cutter 44, and one end of the guide plate 42 is fixedly connected to the piston rod of the second cylinder 43. The working principle is as follows: when the piston rod of the second cylinder 43 extends, the piston rod drives the guide plate 42 to slide in the horizontal direction, and the guide plate 42 drives the pin 45 to slide along the guide slideway on the guide plate 42 when it moves horizontally. At the same time, the sliding pin 45 drives the cutter 44 to slide along the vertical channel on the scissors support plate 41, and the two cutters 44 move toward each other to form a shearing action, thereby achieving the purpose of cutting the cable core. Similarly, when the piston rod of the second cylinder 43 contracts, the two cutters 44 open.

[0039] Example 3

[0040] like Figure 6 As shown, on the basis of Example 2, the utility model further includes a buckling machine 48, which is installed on both sides of the cutter 44. Specifically, slider structures are respectively provided on both sides of the cutter 44, wherein a second slide rail 46 is installed on a horizontal plate, and a second slider 47 is slidably provided on the second slide rail 46, one side of the second slider 47 is fixedly connected to the pin shaft 45, and the other side is fixedly connected to the buckling machine 48.

Specifically, the buckling machine 48 adopts a VK-733 fully automatic micro buckling machine. By setting the buckling machine 48, the two cut wire ends can be bundled to prevent the wrapped protective film from falling off.

[0041] The working principle of this embodiment is roughly the same as that of embodiment 1, and will not be described again here.
