Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wire production technology, and in particular relates to a feeding device for PVC wire sheath production. Background Technology
[0002] PVC wire is a type of wire that uses polyvinyl chloride as insulation material. It is made by adding stabilizers, plasticizers such as dioctyl phthalate, diisodecyl phthalate, dioctyl terephthalate, and trioctyl trimellitate, as well as inorganic fillers such as calcium carbonate, additives, and lubricants. The process involves mixing, kneading, and extruding the mixture. PVC is a plastic material with excellent insulation, oil resistance, and chemical corrosion resistance. PVC wire typically consists of three parts: a conductor, an insulation layer, and a protective layer. The conductor is usually copper or aluminum, the insulation layer is made of PVC, and the protective layer protects the wire from damage caused by the external environment. The production of PVC wire requires the transportation of raw materials.
[0003] Currently, most PVC wire sheath production uses screw feeders to transport raw materials. However, screw feeders cannot dry the raw materials, and the raw materials are easily corroded by moisture during transportation, which affects the insulation performance and strength of the PVC wire sheath after production. Utility Model Content
[0004] The purpose of this utility model is to provide a feeding device for PVC wire sheath production, which aims to solve the problem that the existing PVC wire sheath production mainly uses a screw feeder to transport raw materials, but the screw feeder cannot dry the raw materials, and the raw materials are easily corroded by moisture during transportation, which affects the insulation performance and strength of the PVC wire sheath after production.
[0005] This utility model is implemented as follows: a feeding device for PVC wire sheath production, comprising:
[0006] A feeding box, which is equipped with fixed pipelines and feeding components, is used to transport PVC wire raw materials;
[0007] The feeding assembly includes a feeding pipe, which is fixedly installed on the end face of the feeding box and is used to guide the conveying of raw materials;
[0008] A temperature control component, installed on a fixed pipeline, is used for heat conduction through the feeding pipeline. The temperature control component includes:
[0009] A water tank is fixedly installed on a fixed pipeline, and a fixed cover is rotatably fitted to the top of the water tank;
[0010] An electric heating rod is fixedly installed on the water tank to heat the liquid inside the tank.
[0011] The display screen is fixedly installed in the water tank and is used to display the temperature of the liquid in the tank.
[0012] A delivery pump is fixedly installed on a water tank, and the inlet end of the delivery pump is connected to the water tank;
[0013] The heating tube is fixedly installed at the liquid outlet end of the delivery pump. The heating tube consists of three parts: a liquid outlet section, a winding section, and a return section. The winding section is fixedly wound around the outer wall of the feeding pipe, and the return section is fixedly connected to the water tank.
[0014] As a further aspect of this utility model, it also includes:
[0015] Temperature monitoring unit is used to monitor the temperature of the feeding pipeline;
[0016] The liquid level monitoring unit is used to monitor the height of the liquid in the water tank.
[0017] As a further embodiment of this utility model, the feeding assembly further includes:
[0018] A motor is fixedly installed at the free end of the feeding box, and the output end of the motor is connected to a feeding shaft;
[0019] The feeding blades are fixedly installed on the feeding shaft and are used to provide power for conveying raw materials;
[0020] The pitch of the feeding blades gradually decreases from the direction closer to the motor to the direction farther away from the motor, which is used to pressurize and transport the raw materials for wire production.
[0021] As a further embodiment of this utility model, a ventilation component is also included, which is disposed on a fixed duct for ventilating and purifying the air. The ventilation component includes:

[0024] Molecular sieve filter plates are snapped onto the inner wall of the ventilation box to filter small dust particles.
[0025] Activated carbon filter plates are snapped onto the inner wall of the ventilation box near the molecular sieve filter plate to purify air odors.
[0026] As a further embodiment of this utility model, a ventilation fan is installed inside the ventilation box, and ventilation holes are provided on the end face of the ventilation box to accelerate airflow.
[0027] As a further embodiment of this utility model, a feeding hopper is fixedly installed on the top of the feeding box, and the feeding hopper is funnel-shaped.
[0028] This utility model provides a feeding device for PVC wire sheath production. Through the setting of a constant temperature component, heated liquid is circulated. The heat conduction of the liquid heats the conveyed raw materials, while simultaneously causing water vapor to evaporate. This ensures that no moisture accumulates along the material's conveying path, preventing the raw materials from absorbing moisture, sticking, solidifying, and expanding, resulting in good insulation performance and strength of the produced PVC wire sheath. The feeding component also ensures that the raw materials are moved by the squeezing force of the feeding blades during conveying. The material at the end falls off due to pressure, preventing material blockage during conveying. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0034] It is understood that the terms “first” and “second” as used herein may be used to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.
[0035] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0036] like Figures 1 to 3 As shown, a feeding device for PVC wire sheath production according to an embodiment of the present invention includes:
[0037] The feeding box 1 is equipped with a fixed pipeline 11 and a feeding assembly 2 for conveying PVC wire raw materials.
[0038] The feeding assembly 2 includes a feeding pipe 21, which is fixedly installed on the end face of the feeding box 1 and is used to guide the conveying of raw materials;
[0039] Thermostatic component 3, installed on fixed pipeline 11, is used for heat conduction on feeding pipeline 21. Thermostatic component 3 includes:
[0040] Water tank 31 is fixedly installed on fixed pipe 11, and the top of water tank 31 is rotatably fitted with a fixed cover;
[0041] An electric heating rod 32 is fixedly installed on a water tank 31 and is used to heat the liquid inside the water tank 31.
[0042] The display screen 33 is fixedly installed in the water tank 31 and is used to display the temperature of the liquid in the water tank 31;
[0043] The delivery pump 34 is fixedly installed on the water tank 31, and the inlet end of the delivery pump 34 is connected to the water tank 31.
[0044] Heating tube 35 is fixedly installed at the liquid outlet end of delivery pump 34. Heating tube 35 consists of three parts: liquid outlet section, winding section and return section. The winding section is fixedly wound around the outer wall of the feeding pipe 21, and the return section is fixedly connected to the water tank 31.
[0045] Specifically, as a further embodiment of this utility model, it also includes:
[0046] A temperature monitoring unit is used to monitor the temperature of the feeding pipe 21;
[0047] The liquid level monitoring unit is used to monitor the liquid level in the water tank 31.
[0048] In this embodiment of the utility model, in practical application, the raw materials for PVC wire sheath production are conveyed through the feeding box 1 and the feeding component 2. The electric heating rod 32 heats the liquid inside the water tank 31, and the temperature inside the water tank 31 is displayed in real time on the display screen 33. The conveying pump 34 conveys the heated liquid, allowing the liquid to circulate through the heating pipe 35. When the heated liquid flows through the winding section of the pipe, it conducts heat to the feeding pipe 21, keeping the inside of the feeding pipe 21 at a constant temperature. This prevents water vapor from accumulating inside the feeding pipe 21 and prevents the raw materials from being corroded by water vapor, thus maintaining a better drying effect for the raw materials. During the conveying of raw materials, the temperature monitoring unit monitors the temperature inside the feeding pipe 21 in real time. When the temperature is too high, the conveying pump 34 stops conveying the heated liquid, and the electric heating rod 32 also stops heating the liquid. The liquid level monitoring unit can monitor the liquid level in the water tank 31 in real time and issue a warning on the display screen 33 when the liquid is insufficient, reminding the staff to replenish the liquid.
[0049] By setting up the constant temperature component 3, the heated liquid is circulated and heated. The raw materials are heated by the heat conduction of the liquid. At the same time, the water vapor is evaporated by the heat, ensuring that no moisture accumulates on the path of the raw materials. This prevents the raw materials from absorbing moisture, sticking, solidifying and expanding, resulting in good insulation performance and strength of the PVC wire sheath after production.
[0050] like Figures 1 to 3 As shown, in a further embodiment of this utility model, the feeding component 2 further includes:
[0051] Motor 22 is fixedly installed at the free end of the feeding box 1, and the output end of motor 22 is connected to feeding shaft 23;
[0052] The feeding blade 24 is fixedly installed on the feeding shaft 23 and is used to provide power for conveying raw materials;
[0053] The pitch of the feeding blades 24 gradually decreases from the direction closer to the motor 22 to the direction farther away from the motor 22, and is used to pressurize and convey the raw materials for wire production.
[0054] In this embodiment of the utility model, in actual application, the motor 22 drives the feeding shaft 23 to rotate, causing the feeding blades 24 to rotate and feed the raw materials. As the pitch of the feeding blades 24 gradually decreases, the pressure of the raw materials during feeding gradually increases, preventing the raw materials from clogging the feeding pipe 21.
[0055] like Figures 1 to 3 As shown, as a further embodiment of this utility model, a ventilation component 4 is also included, which is disposed on the fixed pipe 11 for ventilating and purifying the air. The ventilation component 4 includes:
[0056] The ventilation box 41 is fixedly installed on the fixed pipe 11 on the side near the water tank 31;
[0057] The electrostatic dust collector 42 is snapped onto the end face of the ventilation box 41 and is used to electrostatically adsorb large dust particles.
[0058] Molecular sieve filter plate 43 is snapped onto the inner wall of ventilation box 41 and is used to filter small dust particles.
[0059] Activated carbon filter plate 44 is snapped onto the inner wall of ventilation box 41 near the molecular sieve filter plate 43, and is used to purify air odors.
[0060] Specifically, as a further embodiment of this utility model, a ventilation fan is installed inside the ventilation box 41, and ventilation holes are opened on the end face of the ventilation box 41 to accelerate the airflow.
[0061] In this embodiment of the utility model, during actual application, when feeding and conveying raw materials, the fan is started to accelerate the surrounding airflow. The air passes through the electrostatic dust removal box 42 to electrostatically adsorb dust particles, preventing the dust particles from floating. The air is then purified by passing through the molecular sieve filter plate 43 and the activated carbon filter plate 44, increasing the safety of workers when feeding and conveying PVC raw materials.
[0062] like Figures 1 to 3 As shown, as a further embodiment of the present utility model, a feeding hopper 12 is fixedly installed on the top of the feeding box 1, and the feeding hopper 12 is funnel-shaped.
[0063] In this embodiment of the utility model, it is convenient to pour in the raw materials, so that the raw materials enter the feeding pipe 21 through the feeding shaft 23 for conveying and feeding.
[0064] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
