Description

Technical Field

[0001] The invention relates to the field of wire-paying machines, and in particular to an automatic radio frequency cable wire-paying machine. Background Art

[0002] The automatic RF cable pay-off machine is an automated device specially designed for processing RF cables. It can automatically pay-off RF cables according to a certain length, speed and tension during the production process to ensure the accuracy and consistency of the cables in subsequent processing. The equipment achieves efficient and stable pay-off of RF cables through a precise mechanical structure and control system, reducing the error and labor intensity of manual operation. At the same time, the automatic RF cable pay-off machine is also easy to maintain and has strong adaptability, and can meet the pay-off needs of RF cables of different specifications and models.

[0003] A Chinese patent with publication number CN107465063B discloses an automatic wire pay-off machine for a terminal crimping machine, including a base, a wire feeding lower guide wheel, a wire feeding lower guide wheel, a wire feeding machine bracket and a wire pay-off machine. The wire pay-off lower guide wheel drives the wire pay-off lower guide wheel slide to rise along the wire pay-off slide bar. The wire is always in a tensioned state under the gravity of the wire feeding lower guide wheel according to the processing speed of the crimping machine, which significantly improves the wire feeding quality and processing quality.

[0004] When the automatic wire-releasing machine of the above-mentioned patent is releasing the wire, the wire will be stored on the drum in advance. When the wire is pulled to release the wire, the wire will drive the roller to rotate, and the rotation will generate inertia. When the wire stops being taken out, even if the wire is not pulled, the inertia of the roller will drive the wire to be discharged from the outside of the drum by itself, causing part of the wire to be detached from the winding of the drum. The wire is not tightly wound on the outside of the drum, which is easy to cause knots. Summary of the invention

[0005] The object of the present invention is to provide an automatic radio frequency cable pay-off machine. When the first limiting wheel presses and fixes the cable, the second transmission plate can be attached to the roller and fix the roller through the transmission of the transmission assembly. When the cable is pulled and discharged, the first limiting wheel moves longitudinally upward and the second transmission plate is driven by the transmission assembly to move away from the roller, so that the roller can rotate normally and discharge the cable, avoiding the cable from being stranded outside the roller, thereby solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatic radio frequency cable pay-off machine, comprising a drum, a base is laterally arranged at the lower end of the drum, a first limiting wheel is arranged on one side of the drum, and a transmission assembly consisting of a first gear, a second gear, a transmission roller, a third gear and a transmission belt for external transmission of the transmission roller and the second gear is arranged at the front end of the drum, the transmission roller is laterally located at one end of the drum, the third gear is welded to one end of the transmission roller, the first gear is located between the first limiting wheel and the transmission roller, and the second gear is located between the first gear and the transmission roller and is meshed with the outside of the first gear.

[0007] Preferably, connecting blocks are provided at both the front and rear ends of the first limiting wheel, and wrapping frames are provided outside the two connecting blocks, and the connecting blocks are embedded in the wrapping frames and slidably connected with the inside of the wrapping frames.

[0008] Preferably, a sliding rail is provided through one of the wrapping frames close to the first gear, a first transmission plate meshingly connected to the outside of the first gear is provided inside the sliding rail, and one side of the first transmission plate is welded and fixed to the outer wall of the connecting block inside the corresponding wrapping frame.

[0009] Preferably, a second transmission plate meshingly connected to the third gear is provided at the lower end of the third gear, a support plate is provided between the outer lower end of the second transmission plate and the upper end of the base, and the outer upper end of the support plate is slidably connected to the outer lower end of the second transmission plate.

[0010] Preferably, a rubber pad overlapping with the second transmission plate is provided at the center position of one end of the roller facing the second transmission plate.

[0011] Preferably, fixing rods are provided at both front and rear ends between the first limiting wheel and the drum, limiting rollers are provided inside the two fixing rods toward the middle of the drum, and the upper and lower ends of the limiting rollers are rotatably connected to the inside of the fixing rods respectively.

[0012] Preferably, a second spring is provided between a position where the lower end of the second transmission plate is embedded in the interior of the support plate and one end of the interior of the support plate.

[0013] Preferably, a first spring is provided between the position where the connecting block is embedded in the wrapping frame and the upper end of the interior of the wrapping frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. When the cable is pulled externally and the cable wound on the outside of the drum is discharged and transmitted, the pulling of the cable will make the cable between the second limiting wheel and the drum straighten, and the straightened cable will drive the first transmission plate to move longitudinally by the connecting block, and the longitudinal movement of the first transmission plate drives the second transmission plate that is in contact with the drum to move away from the drum after being driven by the first gear, the second gear, the transmission belt and the third gear in the transmission assembly. On the contrary, after stopping pulling the cable, the resilience of the first spring and the resilience of the second spring, together with the transmission of the transmission assembly, can make the second transmission plate repeatedly fit the rubber pad, and the first limiting wheel will repeatedly press the cable and embed it into the reserved groove, the pressing of the first limiting wheel will limit the excess cable, and the second transmission plate fitting the rubber pad can offset the inertia of the drum during rotation, thereby reducing more cables from being discharged from the outside of the drum when the cable is not pulled.

[0016] 2. The present invention provides a pair of fixing rods between the drum and the first limiting wheel at the pressing position. When the cable is pulled and stably transmitted outward through the first limiting wheel and the second limiting wheel, the flow direction of the cable is limited by the pair of fixing rods, so that the cable can stably contact the connecting block and be transmitted toward the second limiting wheel no matter how it is wound around the outside of the drum, thereby preventing the transmitted cable from losing the restriction of the connecting block and preventing the subsequent downward pressure of the connecting block from failing to press the transmitted cable.

DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with specific embodiments.

[0026] Example 1

[0027] like Figure 1 As shown, an automatic radio frequency cable pay-off machine of the present embodiment includes a drum 1, and the cable to be subsequently paid out will be pre-wound on the outside of the drum 1, and a base 2 is transversely arranged at the lower end of the drum 1, and the front and rear ends of the base 2 are rotatably connected to the front and rear ends of the drum 1. After pulling the cable, the drum 1 will rotate at the upper end of the base 2 and release the cable to complete the release;

[0028] In order to improve the stability of the defense line, a first limiting wheel 4 is provided on one side of the drum 1, and a second limiting wheel 5 is provided on one side of the first limiting wheel 4. The cable released from the outside of the drum 1 will contact the lower end of the outside of the first limiting wheel 4 and the upper end of the second limiting wheel 5 respectively, and the other side of the second limiting wheel 5 is pulled to complete the release of the cable;

[0029] Among them, Figure 2 and Figure 3 As shown, the front and rear ends of the first limiting wheel 4 are both provided with connecting blocks 8, and the outsides of the two connecting blocks 8 are both provided with wrapping frames 17, and the connecting blocks 8 are embedded in the wrapping frames 17 and are slidably connected with the inside of the wrapping frames 17. When the cable is pulled and the wire is protected, the cable will be straightened and will drive the first limiting wheel 4 to move longitudinally upward, and when the first limiting wheel 4 moves longitudinally upward, the connecting blocks 8 will slide in the wrapping frames 17;

[0030] In addition, a transmission assembly is provided at the front end of the drum 1, such as Figure 4 , Figure 5 and Figure 6As shown, the transmission assembly consists of a first gear 11, a second gear 12, a transmission roller 13, a third gear 14 and a transmission belt. The transmission roller 13 is laterally located at one end of the drum 1, and the third gear 14 is located at one end of the transmission roller 13. The transmission roller 13 and the third gear 14 are welded and fixed. The rotation of the transmission roller 13 will synchronously drive the third gear 14 to rotate. The first gear 11 is located between the first limiting wheel 4 and the transmission roller 13, and the second gear 12 is located between the first gear 11 and the transmission roller 13. The transmission roller 13 is connected to the outside of the second gear 12 through a transmission belt transmission. The outside of the first gear 11 is meshed with the outside of the second gear 12. After the transmission of the transmission assembly, the rotation of the first gear 11 can drive the third gear 14 to rotate. The synchronous rotation can adapt to the pulling cable and the rotation of the fixed drum 1.

[0031] In order to stop the restriction on the drum 1 when the first limiting wheel 4 moves longitudinally, Figure 5 and Figure 7 As shown, one of the wrapping frames 17 near the first gear 11 is penetrated by a sliding rail 20, and a first transmission plate 10 is arranged inside the sliding rail 20, and one side of the first transmission plate 10 is welded and fixed to the outer wall of the connecting block 8 inside the corresponding wrapping frame 17. When the cable is pulled, the cable will drive the first transmission plate 10 connected at one end to move longitudinally through the connecting block 8, and the first transmission plate 10 is meshed and connected with the outside of the first gear 11 on one side facing the first gear 11;

[0032] Among them, Figure 4 and Figure 5 As shown, a second transmission plate 15 is provided at the lower end of the third gear 14, and the upper end of the outer part of the second transmission plate 15 is meshedly connected with the lower end of the outer part of the third gear 14, a support plate 19 is provided between the lower end of the outer part of the second transmission plate 15 and the upper end of the base 2, and the upper end of the outer part of the support plate 19 is slidably connected with the lower end of the outer part of the second transmission plate 15, and the second transmission plate 15 is restricted by the support plate 19, so that the third gear 14 will drive the second transmission plate 15 to move toward or away from the drum 1 when rotating;

[0033] In addition, a rubber pad 16 is provided at the center of one end of the drum 1 facing the second transmission plate 15, and the rubber pad 16 overlaps with the second transmission plate 15. When the third gear 14 rotates and pushes the second transmission plate 15, the second transmission plate 15 contacts and squeezes the rubber pad 16, and the inertia generated by the rotation of the drum 1 can be offset by squeezing the rubber pad 16.

[0034] In order to limit the transmitted cable and limit and make the cable stably contact the first limiting wheel 4 and the second limiting wheel 5, fixed rods 6 are provided at both ends of the front and rear ends between the first limiting wheel 4 and the drum 1, and limiting rollers 7 are provided inside the two fixing rods 6 toward the middle of the drum 1, and the upper and lower ends of the limiting rollers 7 are respectively connected to the inside of the fixing rods 6 for rotation. Figure 1 and Figure 2 As shown, when the cable wound outside the drum 1 is transmitted and released, the cable will contact a pair of rotatable limiting rollers 7 and pass out from a pair of fixed rods 6, pass out from the pair of fixed rods 6 and be stably pressed by the first limiting wheel 4, so as to prevent the cable from falling off from the pressing position of the first limiting wheel 4 and the connecting block 8 during the transmission process;

[0035] In order to enable the connection block 8 and the second transmission plate 15 to be actively reset, actively reset and fix the cable when the cable is stopped being pulled, a second spring 18 is provided between the position where the lower end of the second transmission plate 15 is embedded in the support plate 19 and one end of the support plate 19;

[0036] In addition, a first spring 9 is provided between the position where the connecting block 8 is embedded in the wrapping frame 17 and the upper end of the wrapping frame 17, and the first limiting wheel 4 and the second transmission plate 15 can be actively reset by the resilience of the first spring 9 and the second spring 18;

[0037] Example 2

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, a groove 3 is provided inside the base 2 toward the position of the first limiting wheel 4. When the first limiting wheel 4 is pushed and reset by the resilience of the first spring 9, the first limiting wheel 4 will be embedded in the groove 3. The recessed groove 3 can improve the stability of the first limiting wheel 4 in embedding and pressing the cable.

[0039] Working principle: When using the device and protecting the cable wound around the outside of the drum 1, pull the cable on the outside of the second limiting wheel 5. After pulling the cable, when the second transmission plate 15 is in contact with the rubber pad 16, the cable between the drum 1 and the second limiting wheel 5 will be straightened. When the cable is straightened, the first limiting wheel 4 will slide vertically upward in the wrapping frame 17. The longitudinal sliding of the first limiting wheel 4 will drive the first transmission plate 10 to move vertically through the connecting block 8. The longitudinal movement of the first transmission plate 10 will drive the second gear 12 to rotate counterclockwise through the first gear 11. The second gear 12 will drive the third gear 14 to rotate counterclockwise through the transmission belt and the transmission roller 13. , the rotation of the third gear 14 will drive the second transmission plate 15 away from the rubber pad 16, so that the drum 1 loses its restriction and can rotate to release the cable. After the cable is in the line of defense, the resilience of the first spring 9 and the second spring 18 will respectively push the first limiting wheel 4 and the second transmission plate 15 to move. The first limiting wheel 4 will drive the excess cable to be embedded and fixed in the groove 3, and the resilience of the second spring 18 will push the second transmission plate 15 to repeatedly fit the rubber pad 16 on one side of the drum 1 to offset the inertia of the drum 1 when it is in the line of defense. The resilience of the second spring 18 and the first spring 9, together with the transmission of the transmission assembly, can make the first limiting wheel 4 and the second transmission plate 15 move synchronously.
