Abstract
Description
Technical Field
[0001] This utility model relates to the field of PVC cable material processing technology, specifically a PVC cable material powder mixing machine. Background Technology
[0002] Polyvinyl chloride (PVC) cable compounds are widely used in the wire and cable industry due to their excellent electrical insulation properties, mechanical properties, chemical resistance, and relatively low cost. The performance of PVC cable compounds largely depends on the uniformity of the mixing of their components during the production process. High-quality PVC cable compounds require various powder additives, such as stabilizers, plasticizers, lubricants, and fillers, which must be thoroughly mixed with PVC resin powder to ensure that the final product possesses stable and standard-compliant performance.
[0003] Existing PVC cable material powder mixing machines have the following disadvantages:
[0004] (1) Existing powder mixing machines have low mixing efficiency when mixing crushed cable materials.
[0005] (2) Existing powder mixing machines usually use crushing blades when crushing PVC cable materials, which results in poor crushing effect. Utility Model Content
[0006] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a powder mixer for PVC cable materials with strong crushing effect and high mixing efficiency.
[0007] To solve the above problems, the technical solution of this utility model is as follows: a powder mixing machine for PVC cable materials, including a crushing box, a crushing mechanism provided inside the crushing box, a mixing barrel fixedly connected to the lower side of the crushing box, a stirring mechanism provided inside the mixing barrel, a discharge port opened at the bottom of the crushing box, a discharge pipe connected to the bottom of the mixing barrel, a solenoid valve connected to the outside of the discharge pipe, and a heating coil fixedly connected to the bottom of the mixing barrel.
[0008] Furthermore, the crushing mechanism includes a connecting seat, which is fixedly connected to one side of the crushing box. A motor base is fixedly connected to the inner side of the connecting seat, and a double-headed motor is connected to the upper side of the motor base. Rotating rods are fixedly connected to the output ends of the double-headed motor on both sides.
[0009] Furthermore, the ends of the two rotating rods are respectively fixedly connected to a first bevel gear, and a second bevel gear is respectively meshed on one side of the two first bevel gears. A rotating shaft is respectively connected to one side of the two second bevel gears. The two rotating shafts are respectively rotatably connected to the inside of the crushing box, and a crushing roller is respectively fixedly connected to the outside of the two rotating shafts.
[0010] Furthermore, the two first bevel gears and the two second bevel gears are respectively located at the ends of the connecting seat.
[0011] Furthermore, the stirring mechanism includes a stirring motor, which is connected to the bottom of the mixing tank. The output end of the stirring motor is fixedly connected to a stirring shaft, and a plurality of stirring blades are fixedly connected to the outside of the stirring shaft.
[0012] The advantages of this invention compared to existing technologies are as follows:
[0013] (1) This utility model is equipped with a stirring mechanism and a heating coil. The stirring motor of the stirring mechanism drives the stirring shaft to rotate, and multiple stirring blades are set on the stirring shaft. This design enables the stirring blades to form material flow in different directions and layers in the mixing barrel, thereby fully stirring the material and allowing PVC resin powder and various additives to be mixed more evenly, improving the uniformity of mixing and helping to improve the performance stability of PVC cable materials. The heating coil fixedly connected to the bottom of the mixing barrel can heat the material in the mixing barrel. During the mixing process, by controlling the temperature of the heating coil, the mixing temperature of the material can be adjusted according to the formulation and process requirements of different PVC cable materials. Appropriate temperature helps to improve the fluidity of the material, promote better integration between the components, further improve the mixing effect, and also meet the temperature requirements of some special formulations.
[0014] (2) This utility model is equipped with a crushing mechanism, which uses a double-headed motor to drive two rotating rods. The rotating rods drive the two rotating shafts to rotate through the meshing of the first bevel gear and the second bevel gear, thereby driving the crushing rollers to work. This double-roller crushing structure allows the material to be subjected to multiple actions such as squeezing, shearing and grinding between the two relatively rotating crushing rollers, effectively crushing larger particles into smaller particles, providing raw materials with more uniform particle size for subsequent mixing processes, and helping to improve the mixing quality of the final PVC cable material.

[0023] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0024] like Figures 1 to 5 As shown, a PVC cable material powder mixer includes a crushing box 1, a crushing mechanism 2 inside the crushing box 1, a mixing barrel 3 fixedly connected to the lower side of the crushing box 2, a stirring mechanism 4 inside the mixing barrel 3, a discharge port 5 at the bottom of the crushing box 1, a discharge pipe 6 connected to the bottom of the mixing barrel 3, a solenoid valve 7 connected to the outside of the discharge pipe 6, and a heating coil 8 fixedly connected to the bottom of the mixing barrel 3. During the mixing process, by controlling the temperature of the heating coil 8, the mixing temperature of the materials can be adjusted according to the formulation and process requirements of different PVC cable materials. Appropriate temperature helps improve the fluidity of the materials, promotes better integration between components, further improves the mixing effect, and also meets the temperature requirements of some special formulations.
[0025] The crushing mechanism 2 includes a connecting seat 201, which is fixedly connected to one side of the crushing box 1. A motor seat 202 is fixedly connected to the inner side of the connecting seat 201. A double-headed motor 203 is connected to the upper side of the motor seat 202. Rotating rods 204 are fixedly connected to the output ends of the two rotating rods 204. First bevel gears 205 are fixedly connected to the ends of the two rotating rods 204. Second bevel gears 206 are meshed on one side of the two first bevel gears 205. Rotating shafts 207 are connected to one side of the two second bevel gears 206. The two rotating shafts 207 are rotatably connected to the inner side of the crushing box 1. Crushing rollers 208 are fixedly connected to the outer side of the two rotating shafts 207. The two first bevel gears 205 and the two second bevel gears 206 are located at the ends of the connecting seat 201. A dual-head motor 203 drives two rotating rods 204, which in turn drive two rotating shafts 207 to rotate through the meshing of a first bevel gear 205 and a second bevel gear 206. This, in turn, drives the crushing rollers 208 to operate. This dual-roller crushing structure allows the material to be subjected to various actions such as compression, shearing, and grinding between the two relatively rotating crushing rollers 208, effectively crushing larger particles into smaller ones. This provides more uniformly sized raw materials for subsequent mixing processes, which is beneficial for improving the final mixing quality of the PVC cable material.
[0026] The mixing mechanism 4 includes a mixing motor 401, which is connected to the bottom of the mixing tank 3. A mixing shaft 402 is fixedly connected to the output end of the mixing motor 401, and several mixing blades 403 are fixedly connected to the outer side of the mixing shaft 402. The mixing motor 401 drives the mixing shaft 402 to rotate, and multiple mixing blades 403 are mounted on the mixing shaft 402. This design allows the mixing blades to create material flow in different directions and layers within the mixing tank 3, thereby fully mixing the material and enabling the PVC resin powder and various additives to be mixed more evenly, improving the uniformity of the mixture and contributing to the performance stability of the PVC cable material.
[0027] In practical use, the cable material is placed inside the crushing chamber 1, and the stirring motor 401 drives the stirring shaft 402 to rotate. Multiple stirring blades 403 are installed on the stirring shaft 402. This design allows the stirring blades to create material flow in different directions and layers within the mixing tank 3, thereby fully mixing the material and ensuring that the PVC resin powder and various additives are mixed more evenly. This improves the uniformity of the mixture and helps enhance the performance stability of the PVC cable material. The crushed material falls into the mixing tank 3, and the stirring motor 401 drives the stirring shaft 402 to rotate. Multiple stirring blades 403 are installed on the stirring shaft 402. This design allows the stirring blades to create material flow in different directions and layers within the mixing tank 3, thereby fully mixing the material and ensuring that the PVC resin powder and various additives are mixed more evenly. This improves the uniformity of the mixture and helps enhance the performance stability of the PVC cable material. During the mixing process, the mixing temperature can be adjusted according to the formulation and process requirements of different PVC cable materials by controlling the temperature of the heating coil.
