Description

Technical Field

[0001] This utility model relates to the field of wire and cable production technology, specifically to an automatic wrapping equipment for wire and cable packaging film. Background Technology

[0002] Wire and cable packaging film is a product specifically designed to protect wires and cables. Its main function is to prevent wires and cables from being affected by external factors such as physical damage, moisture, and dust during storage, transportation, and use. Wire and cable packaging film wrapping equipment is an automated device used for wire and cable packaging. It is mainly used to wrap wires and cables in protective film to achieve effects such as dustproofing, moistureproofing, and protection against mechanical damage.

[0003] Chinese Patent Publication No. (CN218113210U) discloses a cable packaging wrapping device, comprising: a mounting base plate; a cleaning mechanism fixedly mounted on the top of the mounting base plate; a working mechanism fixedly connected to the top of the mounting base plate; an abutting mechanism mounted on both sides of the top of the working mechanism; and a rotating mechanism fixedly mounted on the outer wall of the top of the mounting base plate by screws.

[0004] The cleaning mechanism in the aforementioned comparative document relies on the elasticity of the first telescopic spring to drive the cleaning scraper to adhere to the cable. However, the elastic range of the telescopic spring is fixed: for cables that are too thick, the scraper may deform due to excessive compression; for cables that are too thin, the scraper pressure is insufficient, resulting in incomplete cleaning. In addition, the cleaning scraper is fixedly connected and cannot be easily replaced after wear, which will lead to a decrease in cleaning effect with long-term use.

[0005] In view of this, the present invention solves the above-mentioned technical problems by proposing an automatic wrapping device for wire and cable packaging film. Utility Model Content

[0006] To address the shortcomings of the aforementioned background technology, this utility model provides a technical solution for an automatic wrapping device for wire and cable packaging film. Firstly, by rotating a knob to adjust the extension and retraction of the lead screw, the elastic pressure of the compression spring a can be dynamically adjusted, causing the composite cleaning layer (inner sponge and outer brush) to flexibly conform to the surface of cables of different diameters. This avoids excessive compression and deformation of the cleaning layer caused by excessively thick cables, while ensuring sufficient pressure for excessively thin cables, thus solving the problem of poor cleaning adaptability in existing technologies. It can stably adapt to the cleaning needs of various cable specifications. Secondly, a snap-fit ​​structure (a combination of snap-fit ​​and clearance groove) enables a detachable connection between the composite cleaning layer and the connecting plate. When the outer brush or inner... When the sponge layer wears out, it can be quickly disassembled and replaced simply by rotating the clips, without complicated operations, which significantly reduces maintenance difficulty and time costs, ensuring that the cleaning layer always maintains a good clean condition and avoiding a decrease in cleaning effect due to wear of cleaning components. Finally, a composite cleaning layer design is adopted. The outer nylon brush removes coarse particles, dust and other impurities from the cable surface through contact friction, while the inner polyurethane sponge (with an antistatic coating) further adsorbs fine dust, and the antistatic coating can prevent static electricity from adsorbing impurities. The dual cleaning effect significantly improves the cleanliness of the cable surface, providing a cleaner foundation for subsequent wrapping film, and reducing the impact of impurities on the wrapping sealing and stability.

[0007] This utility model provides the following technical solution: an automatic wrapping device for wire and cable packaging film, including a base plate and a wrapping wheel;

[0008] A cleaning frame is fixedly connected to the top of the base plate. Two lead screws are symmetrically threaded to the inner cavity of the cleaning frame. One end of each lead screw is rotatably connected to a spring seat through a bearing. One end of the spring seat is fixedly connected to a compression spring a. The end of the compression spring a away from the spring seat is fixedly connected to a connecting plate. One end of the connecting plate is detachably connected to a composite cleaning layer through a snap-fit ​​structure.

[0009] The composite cleaning layer includes an inner sponge and an outer brush.

[0010] The inner cavity of the base plate is symmetrically slidably connected with multiple guide rods. One end of each guide rod is fixedly connected to the surface of the connecting plate, and the other end of the lead screw is fixedly connected to the knob.

[0011] As a preferred technical solution of this utility model, the snap-fit ​​structure includes two symmetrically through grooves on the surface of the connecting plate, and a buckle is provided in the inner cavity of each groove. One end of the buckle passes through the inner layer of sponge and is rotatably connected to the inner cavity of the outer layer of brush. The buckle is a T-shaped structure.

[0012] As a preferred embodiment of this utility model, a support plate and a mounting frame are fixedly connected to the two sides of the top of the base plate, and the inner cavities of the support plate and the mounting frame are rotatably connected to guide wheels through bearings.

[0013] As a preferred embodiment of this utility model, guide grooves are provided at both ends of the mounting bracket, a connecting block is slidably connected to the inner cavity of the guide groove, a tensioning wheel is rotatably connected to the inner cavity of the connecting block, and a compression spring b is provided between the connecting block and the guide groove.

[0014] As a preferred embodiment of this utility model, a mounting plate is fixedly connected to the center of the top of the base plate, a rotating disk is rotatably connected to one side of the mounting plate, one end of the winding wheel is fixedly connected to one end of the mounting plate, both the rotating disk and the mounting plate are provided with through holes for cables to pass through, the inner cavity of the mounting plate is connected to a gear through a rotating shaft, and the surface of the rotating disk has a plurality of gear teeth arranged in a ring, the gear meshing with the gear teeth.

[0015] As a preferred embodiment of this utility model, one end of the guide wheel and one end of the gear rotating shaft are both connected to a servo motor via a coupling.

[0016] As a preferred embodiment of this utility model, the surface of the knob is provided with anti-slip texture, which is a spaced concave structure.

[0017] As a preferred embodiment of this utility model, the surface of the inner sponge is provided with an antistatic coating, the inner sponge is a polyurethane inner sponge, and the outer brush is a nylon outer brush.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In existing technologies, cleaning mechanisms rely on a first telescopic spring with a fixed elastic range, which cannot adapt to cables of different diameters. Overly thick cables can easily cause the scraper to deform, while overly thin cables will not provide sufficient pressure for thorough cleaning. However, this invention allows for dynamic adjustment of the elastic pressure of the spring a by rotating a knob to adjust the telescopic amount of the lead screw. This enables the composite cleaning layer (inner sponge and outer brush) to flexibly conform to the surface of cables of different diameters. This avoids excessive compression and deformation of the cleaning layer caused by overly thick cables and ensures that overly thin cables receive sufficient pressure. This solves the problem of poor cleaning adaptability in existing technologies and can stably adapt to the cleaning needs of various cable specifications.

[0020] 2. In the existing technology, the cleaning scraper is fixedly connected, which is difficult to replace after wear. Long-term use will lead to a decline in cleaning effect. This utility model realizes the detachable connection between the composite cleaning layer and the connecting plate through a snap-fit ​​structure (the snap-fit ​​and the relief groove cooperate). When the outer brush or inner sponge is worn, it can be quickly disassembled and replaced by simply rotating the snap-fit. No complicated operation is required, which significantly reduces the maintenance difficulty and time cost, ensures that the cleaning layer always maintains a good cleaning condition, and avoids the decline in cleaning effect caused by the wear of cleaning parts.

[0021] 3. The cleaning ability of a single scraper in the existing technology is limited, and it is difficult to remove both coarse particles and fine dust. This utility model adopts a composite cleaning layer design. The outer nylon brush removes coarse particles, dust and other impurities from the cable surface through contact friction, while the inner polyurethane sponge (with antistatic coating) further adsorbs fine dust. The antistatic coating can prevent static electricity from adsorbing impurities. The dual cleaning effect significantly improves the cleanliness of the cable surface, providing a cleaner foundation for subsequent wrapping film, and reducing the impact of impurities on the wrapping sealing and stability.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] Please see Figure 1-4 As shown, an automatic wrapping device for wire and cable packaging film includes a base plate 1 and a wrapping wheel 101;

[0029] A cleaning frame 2 is fixedly connected to the top of the base plate 1. Two screw rods 201 are symmetrically threaded to the inner cavity of the cleaning frame 2. One end of each screw rod 201 is rotatably connected to a spring seat 202 through a bearing. One end of the spring seat 202 is fixedly connected to a compression spring a203. The end of the compression spring a203 away from the spring seat 202 is fixedly connected to a connecting plate 204. One end of the connecting plate 204 is detachably connected to a composite cleaning layer through a snap-fit ​​structure.

[0030] The composite cleaning layer includes an inner sponge 205 and an outer brush 206;

[0031] Multiple guide rods 207 are symmetrically slidably connected to the inner cavity of the base plate 1. One end of the guide rod 207 is fixedly connected to the surface of the connecting plate 204, and the other end of the lead screw 201 is fixedly connected to the knob 208.

[0032] The snap-fit ​​structure includes two symmetrical relief grooves 3 that are symmetrically opened through the surface of the connecting plate 204. Each relief groove 3 has a buckle 301 inserted into its inner cavity. One end of the buckle 301 passes through the inner layer of sponge 205 and is rotatably connected to the inner cavity of the outer layer of brush 206. The buckle 301 has a T-shaped structure.

[0033] Support plates 4 and mounting brackets 401 are fixedly connected to the top two sides of the base plate 1, and guide wheels 402 are rotatably connected to the inner cavities of the support plates 4 and the mounting brackets 401 through bearings.

[0034] The mounting bracket 401 has guide grooves 5 at both ends. A connecting block 501 is slidably connected to the inner cavity of the guide groove 5. A tensioning wheel 502 is rotatably connected to the inner cavity of the connecting block 501. A compression spring b503 is provided between the connecting block 501 and the guide groove 5.

[0035] A mounting plate 6 is fixedly connected to the center of the top of the base plate 1. A rotating disk 601 is rotatably connected to one side of the mounting plate 6. One end of the winding wheel 101 is fixedly connected to one end of the mounting plate 6. Both the rotating disk 601 and the mounting plate 6 have through holes 602 for cables to pass through. The inner cavity of the mounting plate 6 is connected to a gear 603 through a rotating shaft. The surface of the rotating disk 601 has a ring array of multiple gear teeth 604, and the gear 603 meshes with the gear teeth 604.

[0036] One end of the guide wheel 402 and one end of the rotating shaft of the gear 603 are both connected to a servo motor 7 via a coupling.

[0037] The surface of the knob 208 is provided with anti-slip texture, which is a concave structure with intervals.

[0038] The inner sponge 205 has an antistatic coating on its surface. The inner sponge 205 is a polyurethane inner sponge, and the outer brush 206 is a nylon outer brush.

[0039] The cable is first inserted into the cleaning frame 2. The operator adjusts the extension of the lead screw 201 by rotating the knob 208. The lead screw 201 pushes the spring seat 202 to move, so that the compression spring a203 generates elastic pressure and transmits it to the connecting plate 204, which finally drives the composite cleaning layer (inner sponge 205 and outer brush 206) to fit tightly against the cable surface.

[0040] The outer layer brush 206 (nylon material) removes coarse particles, dust, and other impurities from the cable surface through contact friction;

[0041] The inner layer of sponge 205 (polyurethane material with antistatic coating) further adsorbs fine dust, and the antistatic coating prevents static electricity from adsorbing impurities, ensuring the cable surface is clean.

[0042] The guide rod 207 slides synchronously with the connecting plate 204 to ensure the stability of the adhesion between the cleaning layer and the cable; if the cleaning layer is worn, it can be quickly replaced through the snap-fit ​​structure (the snap 301 passes through the relief groove 3 and is rotated to unlock), making maintenance convenient;

[0043] After cleaning, the cable enters the conveying section. The guide wheel 402 on the mounting frame 401 is driven to rotate by the servo motor 7, and the cable is conveyed forward by the friction between the wheel and the cable.

[0044] The tensioning wheel 502 of the mounting bracket 401 is always in contact with the cable surface through the elastic pressure of the compression spring b503, which compensates for the slight fluctuations in the cable diameter, avoids slippage or deviation during transportation, and ensures stable transportation speed.

[0045] The cable, fed to the middle section, passes through the through hole 602 between the mounting plate 6 and the rotating disk 601, and enters the winding station.

[0046] The servo motor 7 drives the gear 603 to rotate via a coupling. The gear 603 meshes with the teeth 604 on the surface of the rotating disk 601, causing the rotating disk 601 to rotate synchronously.

[0047] The winding wheel 101 moves in a circular motion with the rotating disk 601, and the packaging film on its surface is evenly wrapped around the outer circumference of the cable during the rotation process;

[0048] The conveying speed of the guide wheel 402 and the winding speed of the rotary disk 601 are controlled in coordination by the servo motor 7 (e.g., the conveying speed and winding speed are proportionally matched) to ensure that the wrapping film winding density is consistent and to avoid excessive overlap or missed wrapping.
