Description

Technical Field

[0001] This utility model belongs to the technical field of extruder powdering devices for cable processing, specifically relating to an extruder powdering device for cable processing. Background Technology

[0002] Extruders and powder liner machines play a crucial role in cable processing. During cable production, extruders are used to extrude materials such as plastics and coat them onto cable cores to form insulation or sheaths. Powder liner machines, on the other hand, are typically used in the early or middle stages of cable processing to process powdered raw materials through processes such as screening, mixing, and grinding. This ensures the raw materials achieve suitable particle size and uniformity, providing stable material for subsequent extrusion processes and guaranteeing the performance and quality of the cable products.

[0003] In traditional talcum powder coating devices, the adsorption effect of talcum powder on the cable surface is poor. The accumulation of unadsorbed talcum powder not only wastes material but also affects the coating quality. A special structure is needed to solve the problem of accumulated unadsorbed talcum powder, exposing the cable to adsorb talcum powder for subsequent sections, thus solving the problems of uneven talcum powder adsorption and waste. Utility Model Content

[0004] The purpose of this invention is to provide a talc powder tracing device for extruders used in cable processing, in order to solve the problem in the traditional talc powder tracing device mentioned above, where the talc powder adsorption effect on the cable surface is poor, and the accumulated unadsorbed talc powder not only wastes materials but also affects the tracing quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a powder-passing device for an extruder used in cable processing, comprising a powder-passing device body;

[0006] A powder-passing box is provided at the lower middle internal position of the main body of the powder-passing device, and a powder-passing cavity is provided at the upper position of the main body of the powder-passing device.

[0007] The main body of the powder-passing device is powered by an external power source.

[0008] A cable box is provided on the outside of the right side of the powder passage chamber, an outlet is provided on the upper right side of the cable box, and an inlet is provided on the upper left side of the powder passage chamber.

[0009] Tensioning conveyor rollers are symmetrically and inclinedly arranged at the left and right ends and the upper and lower sides of the powder passage cavity, respectively.

[0010] A oscillating roller with a plum blossom-shaped cross-section is provided at the lower middle position of the powder passage cavity;

[0011] The swing roller and the tension conveying roller are provided with a sleeve shaft at the front end and inside the powder passage cavity, and a cavity is opened inside the front side of the powder passage cavity where the sleeve shaft is located. Gears are provided inside and outside the cavity of the swing roller and multiple tension conveying rollers, and chains are provided on the outside of the multiple gears.

[0012] Preferably, the tension conveying roller on one side and the intermediate swing roller rotate within the powder passage cavity via a sleeve shaft, and the chain rotates when the tension conveying roller on one side and the intermediate swing roller rotate.

[0013] Preferably, the external cable is conveyed from the inlet to the outlet via a plurality of tensioning conveyor rollers, and the external cable travels along the underside of the oscillating roller.

[0014] Preferably, the inlet-side tension conveyor roller is externally wrapped with a brush, the powder-passing device has a conveying pump inside its main body, and the powder-passing box stores talc powder.

[0015] Preferably, nozzles are respectively provided at the front and rear ends of the inner side of the powder passage chamber, and the delivery pump is used to transport the medium in the powder passage box to the nozzles for spraying.

[0017] Preferably, rollers are provided at the four lower corners of the main body of the powder-passing device, and handles are provided on one side of the front and rear ends of the powder-passing cavity.

[0018] Compared with the prior art, this utility model provides a powder-passing device for an extruder used in cable processing, which has the following beneficial effects:

[0019] 1. The tension conveyor rollers keep the cable under stable tension during the talc powder application process, preventing the cable from shaking or shifting, and ensuring that the talc powder can be evenly adhered to the cable surface, greatly improving the uniformity of the powder application and thus improving the processing quality of the cable.

[0020] 2. The plum blossom-shaped oscillating roller causes the cable to oscillate and shake when it rotates, effectively shaking off the unadsorbed talcum powder, providing better adsorption conditions for subsequent powder spraying, further improving the adsorption effect and uniformity of talcum powder on the cable surface, improving the powder coating quality of the cable, and ensuring product quality.

[0021] 3. The brush on the inlet side tension conveyor roller can effectively remove dust from the cable surface before the cable enters the powder passing chamber, preventing dust from entering the powder passing chamber and mixing with talc powder, ensuring the purity of talc powder, avoiding the negative impact of impurities on the powder passing effect and cable quality, and reducing the defect rate.

[0022] 4. By using gears and chains for transmission, multiple rollers can be linked together without the need for an additional power source. The rollers are driven to rotate by the movement of the cables themselves, which not only saves energy but also simplifies the equipment structure, reduces equipment costs and maintenance difficulty, and improves the overall operating efficiency of the equipment.

[0029] 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.

[0030] This utility model provides, for example Figure 1-5 The extruder powder-passing device shown includes a powder-passing device body 10 for cable processing;

[0031] A powder-passing box 1 is provided at the lower middle internal position of the powder-passing device body 10, and a powder-passing cavity 9 is provided at the upper position of the powder-passing device body 10.

[0032] The main body 10 of the powder passing device is powered by an external power source;

[0033] A cable box 3 is provided on the outside of the right side of the powder passage chamber 9. An outlet 4 is provided on the upper right side of the cable box 3, and an inlet 8 is provided on the upper left side of the powder passage chamber 9.

[0034] Tensioning conveyor rollers 12 are symmetrically and inclinedly arranged on the left and right ends and the upper and lower sides of the powder passage cavity 9;

[0035] A oscillating roller 13 with a plum blossom-shaped cross-section is provided at the lower middle position of the powder passage cavity 9;

[0036] A sleeve 17 is provided at the front end of the swing roller 13 and the tension conveying roller 12 and inside the powder passage cavity 9. A cavity is opened inside the front side of the powder passage cavity 9 where the sleeve 17 is located. Gears 15 are provided inside and outside the cavity of the swing roller 13 and multiple tension conveying rollers 12. A chain 16 is provided on the outside of the multiple gears 15.

[0037] In this embodiment, the user can place the main body 10 of the sifting device in a suitable working position, and the rollers 2 at the four lower corners can be used to easily move the device. Connect the external power supply to ensure the main body 10 of the sifting device is powered normally. Initialize the device using the control buttons 7 on the controller 6, such as setting parameters like the conveying pump's conveying capacity. Store sufficient talc powder in the sifting box 1 for use in sifting.

[0038] The cable to be processed is led out from the upper right outlet 4 inside the cable box 3 through an external conveying device, and passes through the tension conveying roller 12 on the inlet 8. Since the tension conveying roller 12 is wrapped with a brush 14, the brush 14 will scrub the surface of the cable during the cable movement to remove dust from the cable surface and prevent dust from entering the powder passing chamber 9 and contaminating the talc powder.

[0039] After being washed, the cable enters the powder-passing chamber 9, where tensioning conveyor rollers 12, symmetrically inclined at both ends and the top and bottom of the powder-passing chamber 9, begin to function. The cable moves between the multiple tensioning conveyor rollers 12, which tension the cable, ensuring a stable conveying state during the powder-passing process and preventing slackness, shaking, or other issues that could affect the powder-passing quality.

[0040] When the cable moves to the middle position of the powder-passing chamber 9 under the action of the tension conveyor roller 12, it will pass under the oscillating roller 13 with a quincunx cross-section. As the cable moves, it drives one side of the tension conveyor roller 12 to rotate. Since gears 15 are provided inside and outside the cavity of the oscillating roller 13 and multiple tension conveyor rollers 12, and chains 16 are provided on the outside of the multiple gears 15, the rotation of one side of the tension conveyor roller 12 will drive the oscillating roller 13 to rotate through the chain 16. When the quincunx oscillating roller 13 rotates, it will cause the cable passing under it to oscillate. At this time, the conveying pump inside the powder-passing device body 10 conveys the talc powder in the powder-passing box 1 to the nozzles 11 at the front and rear ends of the inner side of the powder-passing chamber 9. The nozzles 11 spray the talc powder onto the surface of the cable. During the process of the cable being oscillated and shaken by the oscillating roller 13, the unadsorbed talc powder accumulated on the cable can be shaken off, so that the talc powder sprayed by the subsequent nozzles 11 can be better adsorbed on the surface of the cable, improving the powder-passing effect.

[0041] like Figure 1-5 As shown, a tension conveyor roller 12 on one side and a swing roller 13 in the middle rotate within the powder-passing chamber 9 via a sleeve shaft 17. When the tension conveyor roller 12 on one side and the swing roller 13 in the middle rotate, they drive the chain 16 to rotate. External cables are conveyed from the inlet 8 to the inlet via multiple tension conveyor rollers 12, and the movement path of the external cables is close to the underside of the swing roller 13. A brush 14 is wrapped around the outside of the tension conveyor roller 12 on the inlet 8 side. A conveying pump is installed inside the powder-passing device body 10. Talc powder is stored in the powder-passing box 1. Spray pipes 11 are respectively installed at the front and rear ends of the inner side of the powder-passing chamber 9. The conveying pump is used to convey the medium in the powder-passing box 1 to the spray pipes 11. A controller 6 is installed at the lower outer position of the front side of the powder-passing chamber 9. Multiple control buttons 7 are installed on the controller 6. Rollers 2 are respectively installed at the four corners of the lower side of the powder-passing device body 10. Handles 5 are respectively installed on one side of the front and rear ends of the powder-passing chamber 9.

[0042] Preferably, tensioning conveyor rollers 12 are symmetrically and inclinedly arranged on the left and right ends and the upper and lower sides of the powder passage cavity 9. After the cable enters from the inlet 8, it passes through multiple tensioning conveyor rollers 12 in sequence, and moves forward in a zigzag manner between the tensioning conveyor rollers 12 until it exits from the other side of the powder passage cavity 9.

[0043] The symmetrically inclined tensioning conveyor rollers 12 exert tension on the cable through their positional relationship, thus maintaining the cable under tension throughout the powder-passing process. This tension ensures smooth movement of the cable within the powder-passing chamber, preventing uneven powder passage due to cable slack and ensuring the cable processing quality remains consistent.

[0044] The imported 8-sided tension conveyor roller 12 is wrapped with a brush 14. When the cable passes through the tension conveyor roller 12, its surface comes into contact with the brush 14.

[0045] As the cable moves, brush 14 generates relative friction with the cable surface, thereby brushing away the dust adhering to the cable surface. This prevents dust from entering the powder-passing chamber 9, avoids dust mixing with talcum powder, ensures the purity of the talcum powder, and ensures that the powder-passing effect is not affected by impurities.

[0046] The cable passes under the oscillating roller 13 with a quincunx-shaped cross-section at the lower middle position of the powder-passing chamber 9, and the oscillating roller 13 rotates as the cable moves.

[0047] Because the oscillating roller 13 is shaped like a plum blossom, it contacts the cable at different positions during rotation, causing the cable to oscillate and shake. This oscillation and shaking can shake off the talc powder accumulated on the cable but not adsorbed, providing better adsorption conditions for the talc powder sprayed from the subsequent nozzle 11, and improving the uniformity and effect of talc powder adsorption on the cable surface.

[0048] A sleeve shaft 17 is installed at the front end of the oscillating roller 13 and the multiple tension conveying rollers 12 and inside the powder passage cavity 9. Gears 15 are installed in the cavity inside the front side of the powder passage cavity 9 where the sleeve shaft 17 is located. The multiple gears 15 are connected externally by a chain 16. When the cable moves, it drives one side of the tension conveying roller 12 to rotate, which in turn drives the other tension conveying rollers 12 and the oscillating roller 13 to rotate via the chain 16.

[0049] Utilizing the transmission principle of gears and chains, multiple rollers are linked together. When one tensioning conveyor roller 12 rotates due to the movement of the cable, the power is transmitted to other gears via the chain, thereby driving the connected swing roller 13 and other tensioning conveyor rollers 12 to rotate synchronously. This transmission method requires no additional power source, using the movement of the cable itself to achieve the rotation of each roller, which saves energy, simplifies the equipment structure, and improves the overall operating efficiency of the equipment.

[0050] Optionally, two nozzles 11 are provided, which are connected to the internal powder-passing box 1 via a delivery pump to deliver talc powder and spray it alternately in the powder-passing chamber 9, so that the cable adheres to the talc powder more evenly.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
