An automatic radio frequency cable laying machine

Abstract

This invention discloses an automatic radio frequency cable delivery machine, belonging to the field of delivery machines. The automatic radio frequency cable delivery machine of this invention includes a roller, with a base horizontally arranged at the lower end of the roller. A first limiting wheel is arranged on one side of the roller, and a transmission assembly consisting of a first gear, a second gear, a transmission roller, a third gear, and a transmission belt that externally drives the transmission roller and the second gear is arranged at the front end of the roller. This invention solves the problem in existing automatic delivery machines where, during cable delivery, the cable drives the roller to rotate. This rotation generates inertia, and even when the cable stops being removed, the inertia of the roller causes the cable to automatically discharge outside the roller, resulting in some cable detaching from the roller's windings and becoming loosely wound, easily leading to knots. In this invention, when the first limiting wheel presses and secures the cable, the transmission assembly allows a second transmission plate to adhere to and secure the roller.

Description

Technical Field

[0001] This invention relates to the field of cable laying machines, specifically an automatic radio frequency cable laying machine. Background Technology

[0002] An automatic RF cable laying machine is a specialized automated device designed to process RF cables. It automatically lays out RF cables at specific lengths, speeds, and tensions during production, ensuring accuracy and consistency in subsequent processing. Through a sophisticated mechanical structure and control system, this equipment achieves efficient and stable laying of RF cables, reducing errors and labor intensity associated with manual operation. Furthermore, the automatic RF cable laying machine is easy to maintain and highly adaptable, meeting the laying needs of RF cables of different specifications and models.

[0003] Chinese patent CN107465063B discloses an automatic wire feeding machine for terminal crimping machines, including a base, an upper guide roller for feeding, an lower guide roller for feeding, a wire feeding machine bracket, and a wire feeding machine. The lower guide roller for feeding drives the lower guide roller slide to rise along the wire feeding slide rod. Depending on the processing speed of the crimping machine, the wire is always kept in a taut state under the gravity of the lower guide roller for feeding, which significantly improves the wire feeding quality and processing quality.

[0004] In the automatic cable feeding machine of the aforementioned patent, the cable is pre-stored on the roller. When the cable is pulled to feed, the cable will drive the roller to rotate. The rotation will generate inertia. When the cable stops being taken out, even if the cable is not being pulled, the inertia of the roller will cause the cable to be discharged from the outside of the roller on its own. This causes part of the cable to detach from the winding of the roller. The cable is not tightly wound on the outside of the roller, which can easily cause knots. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic radio frequency cable delivery machine. When the first limiting wheel presses and fixes the cable, the transmission component enables the second transmission plate to adhere to and fix the roller. When the cable is pulled and discharged, the first limiting wheel moves longitudinally upward and is driven by the transmission component to move the second transmission plate away from the roller, allowing the roller to rotate normally and discharge the cable, thus preventing the cable from being stuck outside the roller and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic radio frequency cable laying machine, comprising a drum, a base being laterally arranged at the lower end of the drum, a first limiting wheel being 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 externally driving the transmission roller and the second gear being arranged at the front end of the drum, the transmission roller being laterally located at one end of the drum, the third gear being welded to one end of the transmission roller, the first gear being located between the first limiting wheel and the transmission roller, and the second gear being located between the first gear and the transmission roller and meshing 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 a wrapping frame is provided on the outside of both connecting blocks. The connecting blocks are embedded inside the wrapping frame and are slidably connected to the inside of the wrapping frame.

[0008] Preferably, one of the wrapping frames near the first gear is provided with a sliding rail, and the interior of the sliding rail is provided with a first transmission plate that meshes with the exterior of the first gear, 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, the lower end of the third gear is provided with a second transmission plate that meshes with the third gear, and a support plate is provided between the lower outer end of the second transmission plate and the upper end of the base, and the upper outer end of the support plate is slidably connected to the lower outer end of the second transmission plate.

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

[0011] Preferably, a fixing rod is provided at both the front and rear ends between the first limiting wheel and the roller, and a limiting roller is provided inside the two fixing rods facing the middle position of the roller, and the upper and lower ends of the limiting roller are respectively rotatably connected to the inside of the fixing rod.

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

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

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. When the cable is pulled externally and discharged from the outside of the drum, the cable pulling will straighten the cable between the second limiting wheel and the drum. The straightened cable will be driven by the connecting block to move the first transmission plate longitudinally. The longitudinal movement of the first transmission plate, after being driven by the first gear, the second gear, the transmission belt and the third gear in the transmission assembly, will drive the second transmission plate that is in contact with the drum away from the drum. Conversely, after the cable pulling stops, the elasticity of the first spring and the elasticity of the second spring, together with the transmission of the transmission assembly, can make the second transmission plate repeatedly contact 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 contact of the second transmission plate with the rubber pad can counteract the inertia of the drum rotation, reducing the amount of cable discharged from the outside of the drum when the cable is not being pulled.

[0016] 2. The present invention provides a pair of fixed rods between the roller and the first limiting wheel at the pressing position. When the cable is pulled and stably transmitted outward through the first and second limiting wheels, the pair of fixed rods restrict the direction of the cable flow, so that the cable can stably contact the connecting block and be transmitted towards the second limiting wheel no matter how it is wrapped around the outside of the roller. This avoids the transmitted cable losing the restriction of the connecting block and prevents the subsequent pressing of the connecting block from failing to press the transmitted cable.

[0025] The present invention will be further described below with reference to specific embodiments.

[0026] Example 1

[0027] like Figure 1 As shown, an automatic radio frequency cable release machine in this embodiment includes a roller 1. The cable to be released is pre-wound around the outside of the roller 1. A base 2 is horizontally arranged at the lower end of the roller 1, and the front and rear ends of the base 2 are rotatably connected to the front and rear ends of the roller 1. After the cable is pulled, the roller 1 will rotate at the upper end of the base 2 and release the cable, thus completing the release.

[0028] To improve the stability of cable feeding, a first limiting wheel 4 is provided on one side of the roller 1, and a second limiting wheel 5 is provided on one side of the first limiting wheel 4. The cable fed out from the outside of the roller 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 pull the other side of the second limiting wheel 5 to complete the cable feeding.

[0029] Among them, such as Figure 2 and Figure 3 As shown, connecting blocks 8 are provided at both the front and rear ends of the first limiting wheel 4. A wrapping frame 17 is provided on the outside of both connecting blocks 8. The connecting blocks 8 are embedded inside the wrapping frame 17 and are slidably connected to the inside of the wrapping frame 17. When the cable is pulled and released, the cable will move the first limiting wheel 4 vertically upward when it is taut. When the first limiting wheel 4 moves vertically upward, the connecting blocks 8 will slide inside the wrapping frame 17.

[0030] In addition, a transmission component is provided at the front end of roller 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 located laterally 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 and the second gear 12 are connected externally by a transmission belt. The external parts of the first gear 11 and the external parts of the second gear 12 are meshed. After transmission by the transmission assembly, the rotation of the first gear 11 can drive the third gear 14 to rotate. The synchronous rotation can be adapted to the pulling of cables and the rotation of the fixed drum 1.

[0031] In order to stop restricting the roller 1 when the first limiting wheel 4 moves longitudinally, such as Figure 5 and Figure 7 As shown, a sliding rail 20 is provided through one of the wrapping frames 17 near the first gear 11. A first transmission plate 10 is provided 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. The side of the first transmission plate 10 facing the first gear 11 is meshed with the outside of the first gear 11.

[0032] Among them, such as 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 side of the second transmission plate 15 is meshed with the lower end of the outer side of the third gear 14. A support plate 19 is provided between the lower end of the outer side of the second transmission plate 15 and the upper end of the base 2, and the upper end of the outer side of the support plate 19 is slidably connected with the lower end of the outer side of the second transmission plate 15. By restricting the second transmission plate 15 by the support plate 19, the third gear 14 will drive the second transmission plate 15 to move toward or away from the roller 1 when it rotates.

[0033] In addition, a rubber pad 16 is provided at the center of the end of the roller 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 will contact and squeeze the rubber pad 16. By squeezing the rubber pad 16, the inertia generated when the roller 1 rotates can be offset.

[0034] To facilitate the restriction of the transmitted cable and ensure stable contact between the cable and the first limiting wheel 4 and the second limiting wheel 5, fixing rods 6 are provided at both ends of the first limiting wheel 4 and the roller 1. A limiting roller 7 is located inside each fixing rod 6, facing the center of the roller 1, and the upper and lower ends of the limiting roller 7 are rotatably connected to the interior of the fixing rod 6. Figure 1 and Figure 2 As shown, when the cable wound around the outside of the roller 1 is being transmitted and released, the cable will contact a pair of rotatable limiting rollers 7 and be transmitted from a pair of fixed rods 6. The cable is transmitted from the pair of fixed rods 6 and is stably pressed by the first limiting wheel 4, which prevents 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 connecting block 8 and the second transmission plate 15 to actively reset and fix the cable when the cable stops 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 inside the support plate 19.

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

[0037] Example 2

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, the base 2 has a recessed groove 3 facing the first limiting wheel 4. When the elasticity of the first spring 9 pushes the first limiting wheel 4 and causes it to reset, 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 to unwind the cable wound around the outside of the roller 1, the cable on one side of the second limiting wheel 5 is pulled. After the cable is pulled, it will taut the cable between the roller 1 and the second limiting wheel 5 when the second transmission plate 15 is in contact with the rubber pad 16. When the cable is taut, the first limiting wheel 4 will slide longitudinally upward within the wrapping frame 17. The longitudinal sliding of the first limiting wheel 4 will drive the first transmission plate 10 to move longitudinally 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 roller 1 is unrestricted and can rotate to release the cable. After the cable is released, the elasticity of the first spring 9 and the second spring 18 will push the first limiting wheel 4 and the second transmission plate 15 to move respectively. The first limiting wheel 4 will drive the excess cable to be embedded and fixed in the groove 3, while the elasticity of the second spring 18 will push the second transmission plate 15 to repeatedly press against the rubber pad 16 on one side of the roller 1 to counteract the inertia of the roller 1 when releasing the cable. The elasticity of the second spring 18 and the first spring 9, combined with the transmission of the transmission component, can make the first limiting wheel 4 and the second transmission plate 15 move synchronously.
