Description

Technical Field

[0001] This utility model relates to the field of cable production technology, and more specifically, to a pneumatic powder-coating machine that can uniformly apply powder. Background Technology

[0002] Cables are basic materials used to transmit power, signals, or data, consisting of a conductor, insulation layer, shielding layer, and sheath. They are widely used in power, communication, industry, construction, and other fields. In the cable production process, after processes such as metal wire drawing, a plastic sheath is applied to the surface of the metal wire using an extruder. Before the extrusion process, a layer of powder is applied to the surface of the metal wire to prevent the plastic from adhering to the metal wire surface during extrusion.

[0003] In existing powder coating machines, when the powder is applied to metal wires, the mixing device tends to concentrate the powder on one side of the metal wire during unidirectional mixing, resulting in uneven powder application on the metal wire. At the same time, excessive powder is applied to one side of the metal wire, which affects subsequent processing. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a pneumatic powder-coating machine that can uniformly distribute powder concentration in the box by stirring the powder in both directions of the cable, so as to ensure uniform powder coating on both sides of the cable.

[0012] The technical solutions described in this application have at least the following technical effects:

[0013] The powder coating machine has several mixing blades installed in different directions. When the drive mechanism rotates the mixing blades, the mixing blades stir the powder in different directions, so that the powder concentration on both sides of the cable is the same, ensuring that the powder is evenly coated on the cable. The powder throwing mechanism throws off the excess powder on the cable to prevent too much powder from affecting the next processing step. The limiting device pre-limits the cable, so that the cable can adhere to the powder after melting.

[0019] In some embodiments, the drive assembly includes a transmission element disposed on one side of the housing and connected to a rotating rod; it also includes a driver whose output end is connected to the transmission element.

[0020] In some embodiments, the powder-spinning device includes:

[0021] Powder-dispensing box;

[0022] A wheel assembly, disposed within the powder-spinning box, is used for winding and rotating the cable; and

[0036] 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.

[0037] Please see Figure 1 and Figure 2 This utility model provides a pneumatic powder-coating machine capable of uniformly applying powder, comprising a frame 10, a housing 11 disposed above the frame 10 for holding powder, a powder-coating device 20 including several stirring blades 21 and a drive mechanism 22. The stirring blades 21 are arranged in a different direction within the housing 11 to agitate the powder and apply it to the cable from both sides. The drive mechanism 22 is disposed on one side of the housing 11 to drive the stirring blades 21 to rotate. A powder-discarding device 30 is disposed on the cable output end side of the housing 11 to discard excess powder from the cable. A limiting device 40 is disposed at the cable input end of the housing 11 to limit the cable.

[0038] Understandably, the housing 11 is a hollow shell component, which can be, for example, a rectangular shell or a circular shell, but is not limited to this. The stirring blade 21 is a component that contacts and agitates the powder inside the housing 11, such as a spiral stirring blade 21 or a turbine stirring blade 21, but is not limited to this. The drive mechanism 22 is a component that drives the stirring blade 21 to rotate stably, thereby agitating the powder, such as a gear rotation mechanism or a synchronous belt rotation mechanism, but is not limited to this. The powder-spinning device 30 is a component that drives the cable to rotate, causing the cable to rub against an object, and the object removes excess powder from the cable through friction. For example, it can be a wheel set 32, which drives the cable to rotate and wipe away excess powder on the cable. It can also be a brush or a cloth used to wipe away the powder on the surface of the cable, but is not limited to this. The limiting device 40 is a component that supports and limits the cable, such as a limiting roller 43 or a limiting bracket, but is not limited to this.

[0039] As can be seen from the above, the cable of the powder-coating machine passes through the limiting device 40, which limits the cable. Then, the stirring blade 21 in the powder-coating device 20 is set to change direction. When rotating, the stirring blade 21 rotates in different directions, and at the same time, it drives the powder to move towards both ends of the cable, so that the powder is evenly distributed on both sides of the cable. After the cable is limited, it passes through the limiting box 11. Since the powder concentration on both sides is the same inside the box 11, the powder thickness on both sides of the cable after the limit is also the same. Finally, the cable passes through the powder-spinning device 30 to remove excess powder from the cable, so that the powder on the cable is uniform and of moderate thickness.

[0040] As is known, in some embodiments, please refer to Figure 1 The stirring blades 21 are spiral-shaped. Several stirring blades 21 are arranged along the direction of cable conveying.

[0041] Understandably, the shape of the stirring blade 21 within the housing 11 determines the movement and distribution of the powder after the stirring blade 21 stirs the powder. For example, it can be a straight plate stirring blade 21, in which the powder moves in a planar circular motion along the direction of movement of the stirring blade 21, or it can be a spiral stirring blade 21, in which the powder moves in a combination of horizontal and vertical motion along the stirring blade 21, etc., but it is not limited to these.

[0042] With this configuration, the spiral stirring blade 21 is positioned along the cable conveying direction. When the stirring blade 21 stirs the powder, the powder moves along the direction of the stirring blade 21, ensuring that the powder concentration is the same around each section of the cable, making the powder coating on the cable more uniform.

[0043] As is known, in some embodiments, please refer to Figure 3The drive mechanism 22 includes a rotating rod 221, which is disposed inside the housing 11 and connected to several stirring blades 21. The drive assembly 222 is disposed outside the housing 11 and its output end is connected to the rotating rod 221, and is used to drive the rotating rod 221 to rotate, thereby driving the stirring blades 21 to rotate.

[0044] Understandably, the rotating rod 221 is a rod-shaped component that mounts the stirring blade 21 and drives the stirring blade 21 to rotate. For example, it can be a straight rod or a curved rod, but is not limited to these. The drive assembly 222 provides the power component for the rotation of the stirring blade 21. For example, it can be a gear drive component or a timing belt drive component, but is not limited to these.

[0045] As is known, in some embodiments, please refer to Figure 3 The drive assembly 222 includes a transmission component 2221 disposed on one side of the housing 11 and connected to the rotating rod 221, and also includes a driver 2222 whose output end is connected to the transmission component 2221.

[0046] Understandably, the transmission component 2221 is a component that stably transmits the power generated by the driver 2222 to the rotating rod 221. For example, it can be a gear transmission mechanism or a synchronous belt transmission mechanism, but it is not limited to these.

[0047] With this configuration, the transmission component 2221 stably transmits the power generated by the driver 2222 to the rotating rod 221, so that the rotating rod 221 drives the stirring blade 21 to move stably, maintaining the same powder distribution concentration in the box 11.

[0048] As is known, in some embodiments, please refer to Figure 1 The powder-spinning mechanism includes a powder-spinning box 31, a wheel assembly 32 disposed in the powder-spinning box 31 for winding and rotating the cable, and a motor 322 disposed outside the powder-spinning box 31 with its output end connected to the wheel assembly 32 for driving the wheel assembly 32 to rotate. The wheel assembly 32 includes several reels 321 distributed on the same horizontal plane.

[0049] Understandably, the distribution of the rollers 32 within the powder-spinning box 31, and the number and distribution of the guide rollers, determine the cable routing and powder-spinning effect. For example, there could be a single guide roller positioned in the center of the powder-spinning box 31, or two guide rollers arranged vertically within a single plane of the box 11, etc., but these are not limited to these methods. Since the second method provides a better powder-spinning effect, it is recommended to use the second method.

[0050] With this configuration, the setting of wheel group 32 can extend the cable routing path and enhance the powder-spraying effect.

[0051] As is known, in some embodiments, please refer to Figure 4The limiting device 40 includes a frame 41, a slide rail 42 mounted on the frame 41, and includes slide rails 42 arranged laterally and longitudinally, and several limiting rods 43 arranged laterally and longitudinally on the slide rails 42 for limiting the cable. The limiting rods 43 move on the slide rails 42 according to the cable size, and the spacing between the limiting rods is adjusted according to the cable size.

[0052] Understandably, the frame 41 is a component that supports the limiting rod 43. For example, it can be a block-shaped bracket or a base, but it is not limited to these. The limiting rod 43 is set on the horizontal and vertical slide rails 42 to quickly and evenly limit the cable after it is clamped. For example, there can be one limiting rod 43 that supports the cable from the bottom and limits the cable, or there can be multiple limiting rods 43, with one limiting rod 43 supporting the cable at the bottom and two limiting rods 43 clamping and limiting the cable from the left and right ends, etc., but it is not limited to these.

[0053] With this configuration, by setting up the slide rail 42 and the limiting rod 43 that moves left, right, up and down on the slide rail 42, the limiting rod 43 can adapt to clamping cables of different sizes. At the same time, the limiting rod 43 limits the cable from different directions, improving the uniformity of the limiting and the stability of the clamping.

[0054] As can be seen from the above, the cable is introduced from the outside, passes through the limiting device 40 and is clamped by the limiting roller 43. Next, the cable is introduced and passes through the box 11, then introduced into the powder spinning device 30 and wound around the wire wheel 321 in the wheel set 32 ​​on the powder spinning device 30. Then it is led out by the guide wheel 50. Finally, the box 11 and the powder spinning box 31 are covered, the powder passing machine is started, and the stirring blade 21 in the powder feeding device 20 is driven to move and stir the powder to feed the cable.

[0055] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
