Description

Technical Field

[0001] This utility model relates to the field of shielding material preparation technology, specifically to a device for preparing electromagnetic shielding material for cables. Background Technology

[0002] In the cable manufacturing industry, electromagnetic shielding layers are crucial structures for ensuring signal transmission quality and resisting external interference. Among these, metal foil composite tapes (such as aluminum-plastic composite tapes) are widely used in the preparation of shielding layers for various cables due to their excellent shielding performance and cost advantages. The standard preparation process first involves producing wide-width shielding material master rolls through rolling and lamination processes. Then, based on the core diameter and wrapping overlap requirements of the target cable, the wide master rolls must be slit into narrow-width tape reels using slitting equipment for subsequent wrapping processes.

[0003] However, in existing cable electromagnetic shielding material preparation processes, large rolls of wide material need to be slit. The slitting assembly is typically mounted on one or more slitting shafts, and the positioning and locking of each slitting unit relies on a simple bolt and nut mechanism. When it is necessary to switch slitting specifications, i.e., adjust the slitting spacing to produce shielding tapes of different widths, operators must manually loosen the locking bolts using tools, move the slitting blade to the target mark based on experience, and then manually tighten the bolts again to secure it. This adjustment process is cumbersome and time-consuming, thus reducing adjustment efficiency. To address these problems, the inventors propose a cable electromagnetic shielding material preparation device. Utility Model Content

[0004] To address the problem of the cumbersome and time-consuming process of manually loosening the locking bolts when switching slitting specifications or adjusting the blade spacing, this invention aims to provide a device for preparing electromagnetic shielding materials for cables.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: a device for preparing cable electromagnetic shielding material, comprising a base, a support plate fixedly mounted on the top surface of the base, an auxiliary roller rotatably connected between the support plates, a fixed frame fixedly mounted on the top surface of the base, a fixed frame slidably mounted inside the fixed frame, a sliding rod fixedly mounted inside the fixed frame, a positioning plate fixedly mounted on the outer surface of the sliding rod, and the positioning plate fixedly mounted inside the fixed frame, a first extension rod fixedly mounted on one side of the positioning plate, a movable plate slidably mounted on the outer surface of the sliding rod, and multiple movable plates, each with a second extension rod fixedly mounted on one side, and a guide rod rotatably connected to the outer surfaces of the first and second extension rods. The guide rod has a first cylinder installed on the top surface of the fixed frame. A connecting plate is fixed on the top surface of one of the movable plates. The output end of the first cylinder is fixedly connected to one side of the connecting plate. First, the shielding material produced by rolling and composite processes is placed on the unwinding device. Then, the shielding material passes through the bottom surface of the auxiliary roller, then through the top surface of the rotating roller, and then through the bottom surface of another set of auxiliary rollers and is fixed in the winding device. Then, the first cylinder is turned on, so that the connecting plate drives one of the movable plates to slide on the outer surface of the slide rod (the number of movable plates is four, and the four sets of movable plates and the positioning plate are connected to each other). The guide rod is hinged to the outer surface of the first extension rod and the second extension rod, so that the distance between the five sets of circular knives can be adjusted at the same time. Next, the first motor is turned on, causing the threaded rod to rotate and drive the threaded plate to move, thereby causing the fixed frame to slide within the fixed frame. This allows the position of the five sets of circular knives to be adjusted. Then, the second cylinder is turned on, causing the U-shaped frame to slide the rotating roller upward, while simultaneously causing the slider to slide within the fixed frame. This allows the rotating roller to rise and support the shielding material. Next, the second motor is turned on, causing the rotating shaft to drive the rotating drum and movable block to rotate, while simultaneously driving the circular knives to rotate, thereby cutting the shielding material. At the same time, the winding device is turned on to wind up the material.

[0006] Preferably, an auxiliary plate is fixedly provided on the bottom surface of both the positioning plate and the moving plate. A rotating cylinder is rotatably provided inside the auxiliary plate. A circular knife is fixedly sleeved on the outer surface of the rotating cylinder. A limiting ring is fixedly sleeved on the outer surface of the rotating cylinder. A limiting groove is opened in the auxiliary plate. The limiting ring is rotatably disposed in the limiting groove. A first motor is installed on one side of the fixing frame. A threaded rod is fixedly provided at the output end of the first motor. A mounting frame is fixedly provided on the top surface of the fixing frame. A threaded plate is fixedly provided on the top surface of the mounting frame. The threaded plate is threadedly sleeved on the outer surface of the threaded rod. An ear plate is installed on the bottom surface of the fixing frame. A second motor is installed on one side of the ear plate. A rotating shaft is fixedly provided at the output end of the second motor. The rotating cylinder is slidably sleeved on the outer surface of the rotating shaft. A groove is opened in the rotating shaft. A movable block is fixedly provided inside the rotating cylinder. The movable block is slidably disposed in the groove.

[0007] Preferably, a second cylinder is installed on the top surface of the base, a U-shaped frame is fixedly provided at the output end of the second cylinder, a rotating roller is rotatably provided inside the U-shaped frame, a sliding groove is provided inside the fixed frame, and sliders are fixedly provided on both sides of the U-shaped frame, with the sliders slidingly disposed in the sliding groove.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By opening the first cylinder, the connecting plate drives one of the moving plates to slide on the outer surface of the slide rod, so that the guide rod is hinged to the outer surface of the first extension rod and the second extension rod, thereby enabling the distance between the five sets of circular blades to be adjusted at the same time. The adjustment is more convenient and the adjustment efficiency is improved. 2. By turning on the first motor, the threaded rod is rotated, which drives the threaded plate to move, thereby causing the fixed frame to slide within the fixed frame. This allows the positions of the five sets of circular blades to be adjusted according to the position of the shielding material, so that they match the position where the shielding material is cut.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Example: Figure 1-7 As shown, this utility model provides a device for preparing electromagnetic shielding material for cables, including a base 1, a support plate 11 fixedly mounted on the top surface of the base 1, an auxiliary roller 12 rotatably connected between the support plates 11, a fixing frame 2 fixedly mounted on the top surface of the base 1, a fixing frame 3 slidably mounted inside the fixing frame 2, a sliding rod 31 fixedly mounted inside the fixing frame 3, a positioning plate 32 fixedly mounted on the outer surface of the sliding rod 31, and the positioning plate 32 fixedly mounted inside the fixing frame 3, a first extension rod 36 fixedly mounted on one side of the positioning plate 32, and a movable plate 33 slidably mounted on the outer surface of the sliding rod 31, the movable plate 33 being provided in multiple ways, and a second extension rod 37 fixedly mounted on one side of each of the multiple movable plates 33, the outer surface of the first extension rod 36 being... A guide rod 38 is rotatably connected to the outer surface of the first extension rod 36 and the second extension rod 37. A first cylinder 34 is installed on the top surface of the fixed frame 3. A connecting plate 35 is fixedly provided on the top surface of one of the movable plates 33. The output end of the first cylinder 34 is fixedly connected to one side of the connecting plate 35. By opening the first cylinder 34, the connecting plate 35 drives one of the movable plates 33 to slide on the outer surface of the slide rod 31. (There are four sets of movable plates 33, and the four sets of movable plates 33 are connected to the positioning plate 32.) This allows the guide rod 38 to be hinged to the outer surface of the first extension rod 36 and the second extension rod 37, thereby enabling the simultaneous adjustment of the distance between the five sets of circular blades 45. The adjustment is more convenient and improves the adjustment efficiency.

[0014] An auxiliary plate 43 is fixedly mounted on the bottom surface of both the positioning plate 32 and the moving plate 33. A rotating cylinder 44 is rotatably mounted inside the auxiliary plate 43. A circular knife 45 is fixedly fitted on the outer surface of the rotating cylinder 44. A limiting ring 46 is fixedly fitted on the outer surface of the rotating cylinder 44. A limiting groove 431 is opened inside the auxiliary plate 43. The limiting ring 46 is rotatably mounted in the limiting groove 431. A first motor 21 is installed on one side of the fixing frame 2. A threaded rod 22 is fixedly mounted on the output end of the first motor 21. A fixed top surface of the fixing frame 3 is... There is a mounting bracket 24, and a threaded plate 23 is fixedly provided on the top surface of the mounting bracket 24. The threaded plate 23 is threadedly sleeved on the outer surface of the threaded rod 22. An ear plate 4 is installed on the bottom surface of the fixing frame 3. A second motor 41 is installed on one side of the ear plate 4. A rotating shaft 42 is fixedly provided at the output end of the second motor 41. A rotating cylinder 44 is slidably sleeved on the outer surface of the rotating shaft 42. A groove 421 is provided in the rotating shaft 42. A movable block 47 is fixedly provided in the rotating cylinder 44. The movable block 47 is slidably disposed in the groove 421.

[0015] By adopting the above technical solution, by turning on the first motor 21, the threaded rod 22 is rotated, which drives the threaded plate 23 to move, thereby causing the fixed frame 3 to slide in the fixed frame 2. This allows the position of the five sets of circular blades 45 to be adjusted according to the position of the shielding material, so that they are adapted to the position where the shielding material is cut. By turning on the second motor 41, the rotating shaft 42 drives the rotating drum 44 and the movable block 47 to rotate, and at the same time drives the circular blades 45 to rotate, thereby enabling the shielding material to be cut.

[0016] A second cylinder 51 is installed on the top surface of the base 1. A U-shaped frame 5 is fixedly installed at the output end of the second cylinder 51. A rotating roller 53 is rotatably installed inside the U-shaped frame 5. A sliding groove 201 is opened inside the fixed frame 2. Slider 52 is fixedly installed on both sides of the U-shaped frame 5. The slider 52 is slidably installed in the sliding groove 201.

[0017] By adopting the above technical solution, by opening the second cylinder 51, the U-shaped frame 5 drives the rotating roller 53 to slide upward, and at the same time drives the slider 52 to slide within the fixed frame 2, thereby enabling the rotating roller 53 to rise and support the shielding material.

[0018] Working principle: First, the shielding material produced by rolling and composite processes is placed on the unwinding device. Then, the shielding material passes through the bottom surface of the auxiliary roller 12, then through the top surface of the rotating roller 53, and then through the bottom surface of another set of auxiliary rollers 12. It is then fixed in the winding device. Then, the first cylinder 34 is opened, which causes the connecting plate 35 to drive one of the moving plates 33 to slide on the outer surface of the slide rod 31. (There are four sets of moving plates 33, and the four sets of moving plates 33 are connected to the positioning plate 32.) The guide rod 38 is hinged to the outer surface of the first extension rod 36 and the second extension rod 37, so that the distance between the five sets of circular knives 45 can be adjusted at the same time. Next, the first motor 21 is turned on, causing the threaded rod 22 to rotate and drive the threaded plate 23 to move, thereby causing the fixed frame 3 to slide within the fixed frame 2, thus allowing the position of the five sets of circular knives 45 to be adjusted. Then, the second cylinder 51 is turned on, causing the U-shaped frame 5 to drive the rotating roller 53 to slide upward, while simultaneously driving the slider 52 to slide within the fixed frame 2, thus allowing the rotating roller 53 to rise and support the shielding material. Next, the second motor 41 is turned on, causing the rotating shaft 42 to drive the rotating drum 44 and the movable block 47 to rotate, while simultaneously driving the circular knives 45 to rotate, thus enabling the shielding material to be cut. At the same time, the winding device is turned on to wind up the material.
