Description

Technical Field

[0001] The utility model relates to the technical field of wire taking-up equipment, and more specifically to a wire taking-up equipment for producing flame-retardant cables. Background Art

[0002] Flame retardant cable, also known as fire-resistant cable, is a special wire and cable designed to slow the spread of fire in the event of a fire.

[0003] After the cable is manufactured, it is necessary to wind the cable through a wire reel. The wire reel is clamped at both ends by the clamping mechanism on the wire-winding device, and then the wire reel is driven by the driving device to rotate for winding. In the prior art, for the upper reel of the wire reel, it is necessary to place the wire reel on the wire-winding device manually or with a hoisting device, and align it with the clamping mechanism of the wire-winding device. Since the weight of the wire reel is relatively large, it is difficult to carry and align, and the labor intensity is high. Although the labor intensity is reduced by the hoisting device, the alignment operation is still required, and it will shake during the hoisting process, which is not easy to operate. In addition, the clamping mechanism in the prior art clamps the wire reel through a manual turntable operation, and the degree of automation is low. Utility Model Content

[0004] In view of the problems existing in the prior art, the utility model aims to provide a wire-winding device for producing flame-retardant cables with automatic reel clamping.

[0005] In order to solve the above problems, the utility model adopts the following technical solutions. A wire take-up device for flame retardant cable production, comprising a wire reel, a limiting hole is provided at the axis of the wire reel, and further comprising:

[0008] The driven cam shaft is rotatably mounted on the second mounting seat and is spaced apart and arranged opposite to the driving cam shaft;

[0009] The pushing mechanism links the driven cam shaft and drives the driven cam shaft to move in the direction of the active cam shaft so as to be inserted into and pulled out of the limiting hole to achieve the clamping and loosening of the wire drum;

[0010] The upper plate mechanism is located at the bottom between the first mounting seat and the second mounting seat, and includes a base, a bearing seat vertically guided and installed in the base, and a telescopic driver that drives the bearing seat to move up and down; the wire drum is placed on the bearing seat and then drives the wire drum to move up and down to realize the upper plate and the lower plate.

[0012] Preferably, a guide hole whose axial direction is consistent with the active cam is formed on the second mounting seat, and a guide shaft is inserted into the guide hole. One end of the guide shaft is rotatably connected to the driven cam, and the other end is connected to the pushing mechanism.

[0013] Preferably, the pushing mechanism comprises a cylinder mounted on one side of the second mounting seat and having an output axial direction parallel to the axial direction of the driven cam shaft, and the output end of the cylinder is connected to the guide shaft via a connecting piece.

[0014] Preferably, a guide groove is formed inwardly on the top of the base, the bearing seat is guided and installed in the guide groove, and the telescopic driver is installed between the guide groove and the bearing seat.

Similarly, the lower drum is the opposite, so there is no need for manual handling, which reduces labor intensity.

[0019] (2) The driven cam can be driven to move toward the active cam through the pushing mechanism, and the wire drum can be clamped in cooperation with the active cam, without the need for manual clamping, thereby improving work efficiency.

[0020] (3) The utility model automatically completes the entire process from placing the wire reel on the reel to clamping it, and the combination of the two greatly improves the overall work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] A wire-taking device for producing flame-retardant cables, comprising a wire reel 1, wherein the axis of the wire reel 1 is provided with a limit hole 11, and further comprising: a frame 2, comprising a first mounting seat and a second mounting seat 22 arranged at intervals; an active cam 3, mounted on the first mounting seat and fitted with the limit hole 11, and transmitted with a rotary driver 31 to drive the active cam 3 to rotate; a driven cam 4, which is guided and rotatably mounted on the second mounting seat 22 and is arranged opposite to the active cam 3 at intervals; a pushing mechanism 5, which links the driven cam 4 and drives the driven cam 4 to telescopically move in the direction of the active cam 3, thereby inserting and pulling out the limit hole 11, so as to achieve clamping and loosening of the wire reel 1; an upper disk mechanism 6, which is located at the bottom between the first mounting seat and the second mounting seat 22, and comprises a base 61, a bearing seat 62 vertically guided and mounted in the base 61, and a telescopic driver 63 that drives the bearing seat 62 to move up and down; the wire reel 1 is placed on the bearing seat 62, thereby driving the wire reel 1 to move up and down to achieve upper and lower disks.

[0032] It is understandable that the rotary driver 31 can be driven by a motor, or a transmission structure such as a reducer or a gear set can be installed. The active cam 3 and the first mounting seat can be matched by a shaft hole, or by a rotating component such as a bearing. The guide installation of the driven cam 4, that is, the guide direction is toward the active cam 3, and the pushing mechanism 5 drives the driven cam 4 to move toward the active cam 3 to achieve the clamping effect, and the reverse movement is to achieve the loosening work. The telescopic driver 63 is a device with telescopic work, and a telescopic device such as a cylinder 51 and a hydraulic cylinder can be used, and the output end is upward, driving the bearing seat 62 to move up and down. For the shape of the active cam 3 and the driven cam 4, the end away from the wire drum 1 needs to have a limiting structure to prevent it from being fully inserted into the limiting hole 11. The limiting structure can use a device with a diameter greater than the diameter of the limiting hole 11, or a conical structure.

[0033] In this way, the wire drum 1 is placed on the bearing seat 62, and the telescopic driver 63 drives the wire drum 1 to move up to the position where the active cam 3 and the driven cam 4 can be inserted into the limiting hole 11, and then the driving mechanism 5 drives the driven cam 4 to be inserted into the limiting hole 11 of the wire drum 1, and the wire drum 1 is pushed so that the active cam 3 is inserted into the limiting hole 11 at the other end of the wire drum 1, so as to tighten the wire drum 1. The telescopic driver 63 drives the bearing seat 62 to move down and reset, and finally drives the active cam 3 to rotate through the rotary driver 31, thereby driving the wire drum 1 to rotate and reel. The fully automatic operation from the upper coil to the clamping of the wire drum 1 is realized.

[0034] In some embodiments, a limiting disk 7 is installed on the active cam 3, a positioning hole 12 is provided on the wire drum 1, and a positioning rod inserted into the positioning hole 12 is movably installed on the limiting disk 7. It can be understood that, by simply clamping the active cam 3 and the driven cam 4, the active cam 3 and the limiting hole 11 may slip during the rotation process, making it difficult to lock the wire drum 1. The positioning rod can be a positioning piece such as a latch, a bolt, etc. With such a configuration, the positioning rod is inserted into the positioning hole 12, and the wire drum 1 and the active cam 3 can be locked in position, ensuring the stability of the active cam 3 driving the wire drum 1 to rotate.

[0035] In some embodiments, the second mounting seat 22 is provided with a guide hole 41 whose axial direction is consistent with the active cam shaft 3, and a guide shaft 42 is inserted into the guide hole 41. One end of the guide shaft 42 is rotatably connected to the driven cam shaft 4, and the other end is connected to the pushing mechanism 5. It can be understood that the cooperation between the guide shaft 42 and the guide hole 41 is a guide cooperation of the shaft hole, and the driven cam shaft 4 can be rotatably connected to the guide shaft 42 through a bearing. Further, the pushing mechanism 5 includes a cylinder 51 installed on one side of the second mounting seat 22 and the output axis is parallel to the axis of the driven cam shaft 4, and the output end of the cylinder 51 is connected to the guide shaft 42 through a connecting member 52. The connecting member 52 can be a long plate, a long rod, etc., and the cylinder 51 and the guide shaft 42 are linked by the connecting member 52. The extension and retraction of the cylinder 51 drives the extension and retraction of the guide shaft 42, thereby driving the extension and retraction of the driven cam shaft 4.

[0036] In some embodiments, the top of the base 61 is recessed to form a guide groove 611, the bearing seat 62 is guided and installed in the guide groove 611, and the telescopic driver 63 is installed between the guide groove 611 and the bearing seat 62. The guide groove 611 has a vertical guiding effect on the bearing seat 62, so that the telescopic driver 63 is more stable when it moves up and down with the bearing plate. Furthermore, the top surface of the bearing seat 62 is set to an arc surface 621 that is adapted to the wire drum 1, and the central axis of the arc surface 621 is located in the same vertical plane as the central axis of the active convex shaft 3. In this way, when the wire drum 1 is placed on the arc surface 621, the axis of the wire drum 1 and the axis of the active convex shaft 3 are also in the same vertical plane, minus the subsequent alignment operation of the wire drum 1.

[0037] In some embodiments, a slope 8 is installed on one side of the base 61. The slope 8 can facilitate the cable drum 1 to roll from the ground to the bearing seat 62, and from the bearing seat 62 to the ground.

[0038] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
