Description

Technical Field

[0001] This utility model relates to the field of cable processing waste recycling technology, specifically a cable processing waste recycling device. Background Technology

[0002] Rubber cables are wires and cables with rubber as the insulation layer and sheath. The insulation layer and sheath are made of natural rubber, styrene-butadiene rubber, ethylene propylene rubber, etc. In addition to meeting the requirements of insulation performance and physical and mechanical properties, they are required to be resistant to aging and wear. Some products require oil resistance and flame retardancy. A large amount of waste is generated in the processing and production of rubber cables. The waste can be recycled and processed into new products.

[0003] The existing utility model patent with publication number CN218256116U discloses a waste recycling device for cable processing, including a fixed chamber with a processing chamber fixedly installed inside. A drive assembly is mounted on the fixed chamber. A stirring rod, with one end penetrating the fixed chamber and extending into the processing chamber, is rotatably connected to the top of the fixed chamber. A filter screen is detachably installed inside the fixed chamber below the stirring rod, and a screw conveyor rod is threaded onto the bottom of the filter screen. This waste recycling device for cable processing, by setting up a filter screen and a brush plate, achieves efficient filtration of the molten waste, thereby improving the quality of the molten waste and thus enhancing the waste recycling effect. It solves the problem that when melting rubber, it is inconvenient to filter the molten rubber, making it difficult to filter out unmelted rubber for remelting, thus reducing the quality of the molten rubber material.

[0004] The aforementioned device is not designed with pre-treatment functions (such as crushing) for waste materials of different sizes and hardness. If large or hard waste materials are put in, it may cause the stirring rod to get stuck and the melting time to be too long, reducing the applicability of the equipment. The heating wire is only installed on the outer wall of the processing chamber, and the heat is conducted to the waste material inside the chamber through the chamber wall, which may easily lead to uneven temperature distribution in the processing chamber: the temperature of the waste material near the chamber wall is too high, which may cause local overheating and carbonization; the temperature of the waste material in the central area is insufficient, and the melting is incomplete. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a waste recycling device for cable processing, which solves the problems of uneven heating and inability to process large pieces of hard waste.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A waste recycling device for cable processing includes a support frame, and a recycling mechanism is provided above the support frame.

[0007] A crushing assembly, located at the top of the support frame, is used to crush waste materials;

[0008] The heating assembly includes a receiving pipe disposed below the crushing assembly. A heating tube is fixedly installed at the bottom end of the receiving pipe. A flow limiting plate is fixedly installed at the rear end of the heating tube. An electric heating arc plate is embedded inside the heating tube. A heat-conducting plate is fixedly installed on the inner wall of the heating tube. A roller is inserted inside the heating tube. A conveying motor is fixedly installed above the heating tube. A drive ring is inserted through the outer side of the shaft of the conveying motor. A transmission ring is fixedly installed at the front end of the roller. A transmission belt is embedded between the drive ring and the outer side of the transmission ring. A limiting frame is fixedly installed at the front end of the heating tube. A fixing rod is fixedly installed at the center of the limiting frame.

[0009] Preferably, the crushing assembly includes a crushing tube fixedly installed at the top of the support frame, a support plate fixedly installed above the crushing tube, a crushing motor fixedly installed above the support plate, a drive shaft fixedly installed at the bottom end of the crushing motor shaft, crushing blades and conformal blades fixedly installed on the outside of the drive shaft, a flow guide shroud fixedly installed at the bottom end of the crushing tube, and a mesh plate fitted at the edge of the flow guide shroud.

[0010] Preferably, the crushing motor is fixedly connected to the crushing tube via a support plate, and the bottom end of the drive shaft passes through the guide shroud and forms a rotatable connection with the guide shroud.

[0011] Preferably, the flow guide is a conical structure, and the bottom end of the flow guide is provided with an annular frame structure connected to the crushing tube. The mesh plate is a quarter-circular structure and is installed in a ring inside the annular frame structure at the bottom end of the flow guide.

[0013] Preferably, the roller cage and the heating tube are rotatably connected, and the inside of the roller cage is provided with an "X"-shaped frame that is rotatably connected to the fixed rod. The bottom of the fixed rod is also fixedly installed with an electric heating arc plate.

[0014] Beneficial effects

[0015] This utility model provides a waste recycling device for cable processing. Compared with the prior art, it has the following advantages:

[0016] (1) The waste recycling device for cable processing, through the setting of the crushing motor, is fixed above the crushing tube by the support plate. After starting, it drives the drive shaft to rotate. The crushing blades on the outside of the drive shaft first crush the large pieces or hard waste materials put into the crushing tube. Since the cross section of the conformal blade matches the conical guide shroud, when the drive shaft rotates, the conformal blade can fit against the inner wall of the guide shroud to further cut the waste materials, ensuring that the waste materials are refined. The annular frame at the bottom of the guide shroud is equipped with a grid plate distributed in a ring. Waste materials that do not reach the opening size of the grid plate will be continuously cut by the conformal blade until the particle size meets the requirements and then fall into the receiving pipe through the grid plate, thereby avoiding large pieces or hard waste materials from directly entering the subsequent process and causing equipment jamming, thus improving the applicability of the equipment to waste materials of different sizes and hardness.

[0017] (2) This waste recycling device for cable processing, through the setting of heating arc plates, has an electric heating arc plate embedded inside the heating tube, and an electric heating arc plate is also installed at the bottom of the fixing rod, forming a double heating structure inside and outside; the heat-conducting plate on the inner wall of the heating tube can evenly conduct the heat of the electric heating arc plate to the material. Driven by the conveying motor, the roller rotates in the heating tube through the cooperation of the transmission belt, drive ring and transmission ring. The auger structure on its outer side drives the waste to move forward slowly. During the process, the waste continuously contacts the heat-conducting plate and the roller, and is heated by both the electric heating arc plate on the inner wall of the heating tube and the electric heating arc plate at the bottom of the fixing rod. This avoids the problem of local overheating or insufficient central temperature caused by heat conduction only by the bin wall, so that the waste is evenly heated and melted during the conveying process.

[0024] 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.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a waste recycling device for cable processing, including a support frame 1, and a recycling mechanism 2 is arranged above the support frame 1.

[0026] The crushing assembly 21, located at the top of the support frame 1, is used for crushing waste materials. The crushing assembly 21 includes a crushing tube 211 fixedly installed at the top of the support frame 1. A support plate 212 is fixedly installed above the crushing tube 211. A crushing motor 213 is fixedly installed above the support plate 212. A drive shaft 214 is fixedly installed at the bottom end of the shaft of the crushing motor 213. Crushing blades 215 and conformal blades 216 are fixedly installed on the outside of the drive shaft 214. A guide shroud 217 is fixedly installed at the bottom end of the crushing tube 211. A grid plate 218 is fitted and installed at the edge of the flow guide 217. The crushing motor 213 is fixedly connected to the crushing tube 211 through the support plate 212. The bottom end of the drive shaft 214 passes through the flow guide 217 and forms a rotatable connection with the flow guide 217. The flow guide 217 has a conical structure. The bottom end of the flow guide 217 is provided with an annular frame structure connected to the crushing tube 211. The grid plate 218 has a quarter-circle structure and is installed in a ring inside the annular frame structure at the bottom end of the flow guide 217.

[0027] Specifically, the position of the crushing motor 213 is restricted by the support plate 212. After the crushing motor 213 is started, it can drive the transmission shaft 214 to rotate. The crushing blade 215 is composed of two types of blades, two double-bladed blades and two four-bladed blades. The distance between the double-bladed blades is greater than that between the four-bladed blades. The cross-section of the conformal blade 216 matches the cone shape of the guide shroud 217. When the transmission shaft 214 rotates, it can drive the crushing blade 215 to perform preliminary crushing of the waste. The conformal blade 216 below can further crush the waste to reduce the particle size of the waste to the point that it can pass through the opening of the grid plate 218. The material that cannot pass through the opening of the grid plate 218 will gradually reduce its particle size under the cutting of the conformal blade 216 until it passes through the grid plate 218.

[0028] The heating assembly 22 includes a receiving pipe 221 disposed below the crushing assembly 21. A heating tube 222 is fixedly installed at the bottom end of the receiving pipe 221. A flow limiting plate 223 is fixedly installed at the rear end of the heating tube 222. An electric heating arc plate 224 is embedded inside the heating tube 222. A heat-conducting plate 225 is fixedly installed on the inner wall of the heating tube 222. A roller 226 is inserted inside the heating tube 222. A conveying motor 227 is fixedly installed above the heating tube 222. A drive ring 228 is inserted through the outer side of the shaft of the conveying motor 227. A transmission ring 229 is fixedly installed at the front end of the roller 226. A transmission belt 2210 is fitted between the outer sides of the drive ring 228 and the transmission ring 229. A limiting bracket 2211 is fixedly installed at the front end of the heat pipe 222. A fixing rod 2212 is fixedly installed at the center of the limiting bracket 2211. The top end of the receiving pipe 221 is a conical structure. The top end of the receiving pipe 221 is connected to the crushing pipe 211, and the bottom end is connected to the rear end of the heating pipe 222. The roller cage 226 is a cylindrical frame structure. The length of the roller cage 226 is less than the length of the heating pipe 222. The auger structure on the outside of the roller cage 226 extends backward to the front side of the flow limiting plate 223. The roller cage 226 and the heating pipe 222 are rotatably connected. An "X" shaped frame is provided inside the roller cage 226, which is rotatably connected to the fixing rod 2212. An electric heating arc plate 224 is also fixedly installed at the bottom of the fixing rod 2212.

[0029] Specifically, the receiving pipe 221 can guide the waste into the heating pipe 222 and store a certain amount of material. The flow limiting plate 223 restricts the rate at which the material enters the heating pipe 222. The conveying motor 227 drives the roller 226 to rotate. The auger structure on the outside of the roller 226 can move the waste forward to the heating area. The waste is heated by the electric arc plate 224 under the heat-conducting plate 225 inside the roller 226 to gradually melt the waste. The rear end of the limiting frame 2211 is fixedly connected to the heating pipe 222 and can limit the rotation angle of the fixing rod 2212. The material will gradually move forward under the drive of the roller 226 and be discharged from the front end of the heating pipe 222 after heating.

[0030] Specifically, the crushing motor 213 is model MHMF042L1U2M, and the conveying motor 227 is model YE5-B3. In addition, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0031] During operation, cable processing waste is first fed into the crushing tube 211. The crushing motor 213 is fixed above the crushing tube 211 via a support plate 212. After starting, it drives the drive shaft 214 to rotate. The crushing blades 215 on the outside of the drive shaft 214 first crush the waste. The conformal blades 216 below, whose cross-section matches the conical guide shroud 217, further cut the waste until the particle size meets the opening requirements of the grid plate 218. The waste then falls through the grid plate 218 into the receiving pipe 221 below. The top of the receiving pipe 221 is connected to the crushing tube 211. Its conical structure guides the waste into the heating tube 222. The flow limiting plate 223 at the rear end of the heating tube 222 restricts the rate at which the waste enters. Simultaneously, the conveyor motor 227 above the heating tube 222 starts, and the drive ring 228 on the outside of its rotating shaft drives the drive ring 229 at the front end of the trolley 226 through the transmission belt 2210, causing the trolley 226 to rotate inside the heating tube 222; the auger structure on the outside of the trolley 226 conveys the waste forward. During the process, the electric heating arc plate 224 embedded inside the heating tube 222 and the electric heating arc plate 224 at the bottom of the fixing rod 2212 release heat, which is conducted through the heat conduction plate 225 to achieve uniform heating, causing the waste to gradually melt; finally, the melted waste is discharged from the front end of the heating tube 222 under the conveying of the trolley 226, completing the recycling process.
