Description

Technical Field

[0001] This utility model relates to the technical field of cable protection pipe production equipment, and more specifically, to a gradient composite device for cable protection pipes. Background Technology

[0002] Cable protection pipes are important facilities that protect cables from external damage and are widely used in power, communication, and municipal engineering projects. With the diversification and complexity of engineering environments, the performance requirements for cable protection pipes are becoming increasingly stringent. They not only need to have good corrosion resistance, high temperature resistance, and impact resistance, but also need to achieve gradient performance changes according to different usage scenarios to adapt to the needs of different depths or environmental areas. For example, adding an external glass fiber reinforcement layer to the cable protection pipe can improve its performance.

[0003] When performing gradient composite preparation operations, a corresponding gradient composite device is usually required. There are many types of gradient composite devices on the market. Most gradient composite devices achieve the effect of gradient composite by controlling the distribution ratio of different raw materials in the mixing chamber to achieve gradient changes in material properties.

[0004] However, this type of cable protection pipe production equipment still has some shortcomings in gradient compounding. For example, it generally relies on static unloading, mainly depending on the material's own gravity and downward flow. Since gradient compounding requires ensuring the accuracy of the raw materials, static unloading easily causes raw materials to adhere to the inner wall of the hopper, further resulting in the amount of raw materials in the mixing chamber being less than the actual required amount, thus affecting the manufacturing accuracy. In view of this, we propose a gradient compounding device for cable protection pipes. Utility Model Content

[0005] The purpose of this invention is to provide a gradient composite device for cable protection pipes to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

Multiple weighing feed hoods are installed above the top cover. A vertical pipe is fixedly installed at the bottom of each feed hood, and a valve is fixedly installed on the vertical pipe. The vertical pipe is connected to the interior of the mixing tank. Multiple vibration motors are fixedly installed on the top cover. A discharge pipe is fixedly installed at the bottom of the mixing tank, and a discharge valve is fixedly installed on the discharge pipe. A stirring motor is installed above the top cover, and a stirring shaft is fixedly installed at the end of the output shaft of the stirring motor. Stirring blades are fixedly installed on the stirring shaft, and the stirring blades are located inside the mixing tank.

[0016] Preferably, a control host is provided on one side of the mixing tank, and a fixed bracket is fixedly installed on the bottom of the control host.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model, by setting multiple vibration motors on the top cover, causes the mixing tank and top cover to vibrate after the raw materials enter the mixing tank through the feed hood and vertical pipe. This causes the raw materials adhering to the feed hood, vertical pipe and inner wall of the mixing tank to fall off, avoiding the measurement deviation caused by the residue of raw materials during static unloading, realizing the full utilization of raw materials, and achieving the effect of improving the accuracy of gradient compound preparation. At the same time, the weighing sensor at the bottom of the feed hood can accurately weigh the raw materials, further ensuring the accuracy of the raw material ratio.

[0019] 2. This utility model uses a stirring motor to drive the stirring shaft and stirring blades to rotate inside the mixing tank, which fully mixes different raw materials. The temperature is controlled by an electric heater outside the mixing tank, which ensures that the raw materials are mixed more evenly at a suitable temperature, thus improving the quality of the material composite. The bottom of the mixing tank is funnel-shaped and combined with a discharge pipe and discharge valve to facilitate the smooth discharge of the mixed raw materials, preparing them for subsequent molding. In addition, by controlling the distribution ratio of different raw materials in the mixing tank, it is possible to achieve gradient composite preparation of material properties.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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] Please see Figures 1-4 This utility model provides a technical solution: a gradient composite device for cable protection pipes, including a mixing tank 1. A top cover 13 is detachably installed on the top of the mixing tank 1. Multiple feeding hoods 20 for weighing are arranged above the top cover 13. A vertical pipe 21 is fixedly installed at the bottom of the feeding hood 20. A valve 211 is fixedly installed on the vertical pipe 21. The vertical pipe 21 is connected to the interior of the mixing tank 1. Multiple first screw feeders 2 are arranged above the mixing tank 1. The discharge end of the first screw feeder 2 is inserted into the corresponding feeding hood 20 to facilitate feeding operations.

[0031] In this embodiment, multiple vibration motors 15 are fixedly installed on the top cover 13, a discharge pipe 10 is fixedly installed at the bottom of the mixing tank 1, a discharge valve 11 is fixedly installed on the discharge pipe 10, a stirring motor 14 is arranged above the top cover 13, a stirring shaft 141 is fixedly installed at the end of the output shaft of the stirring motor 14, a stirring blade 142 is fixedly installed on the stirring shaft 141, the stirring blade 142 is located inside the mixing tank 1, multiple support legs 22 are fixedly installed at the bottom of the feed hood 20, a weighing sensor 221 is fixedly installed between the bottom end of the support leg 22 and the top cover 13, the inner wall of the feed hood 20 has a smooth structure, which can reduce the adhesion of raw materials, through multiple A vibration motor 15 is used to drive the top cover 13 and the mixing tank 1 to vibrate when the first screw feeder 2 feeds the raw material into the feed hood 20 and into the mixing tank 1 through the vertical pipe 21. This causes the raw material adhering to the feed hood 20, the vertical pipe 21 and the inner wall of the mixing tank 1 to fall off. Combined with the weighing sensor 221 on the bottom support leg 22 of the feed hood 20 for accurate weighing, and the valve 211 to control the amount of raw material fed, the problem of raw material residue after static unloading is avoided. This ensures that the amount of raw material in the mixing tank 1 is consistent with the actual requirement, and improves the preparation accuracy of gradient composite. In addition, by controlling the distribution ratio of different raw materials in the mixing tank 1, the preparation of gradient composite materials with different properties can be achieved.

[0032] Specifically, a temperature-controlled electric heater 12 is fixedly installed on the outside of the mixing tank 1. The temperature-controlled electric heater 12 can adjust the appropriate temperature to enhance the mixing effect of the raw materials. The stirring motor 14 is installed on the external frame so that the stirring motor 14 can be assembled normally.

[0033] Furthermore, the mixing tank 1 is supported by an external frame, and the bottom of the mixing tank 1 is funnel-shaped, which allows the mixed raw materials to be discharged smoothly, avoiding accumulation and residue, preparing for subsequent processes, and improving the uniformity and quality of material compounding.

[0034] In addition, the top cover 13 is provided with multiple through holes 131, and the vertical tube 21 and the stirring shaft 141 are inserted and fitted with the corresponding through holes 131. The size of the through holes 131 is larger than the size of the vertical tube 21 and the stirring shaft 141, so that the vertical tube 21 and the stirring shaft 141 can be arranged normally. At the same time, the vibration of the top cover 13 will not cause much interference to the vertical tube 21 and the stirring shaft 141.

[0035] like Figure 1 As shown, a second spiral feeder 3 is provided at the bottom of the discharge pipe 10, and a molding die 30 for composite preparation is provided at the discharge end of the second spiral feeder 3. The second spiral feeder 3 stably conveys the mixed raw materials to the molding die 30, avoiding blockage or flow fluctuation during the conveying process.

[0036] like Figure 1As shown, a control host 4 is provided on one side of the mixing tank 1, and a fixed bracket 40 is fixedly installed at the bottom of the control host 4. The control host 4 can integrate and control the coordinated work of various components, reduce manual operation, and the first screw feeder 2 accurately feeds materials. The operation of stirring, heating, vibration and other functions is coordinated, which improves the production efficiency and the stability of the device operation, and meets the continuous production requirements of the gradient composite of cable protection pipes.

[0037] It is worth noting that after the raw material weight value is set in the control host 4, the weighing sensor 221 weighs the weight in real time. When the weight meets the threshold set in the control host 4, the control host 4 controls the first screw feeder 2 to stop working. After the first screw feeder 2 stops working, the control host 4 continues to control the valve 211 to open, and the stirring motor 14 and the temperature-controlled electric heater 12 to work. By setting the working time of the stirring motor 14 and the temperature-controlled electric heater 12 in the control host 4, the stirring operation is completed after the specified stirring and heating time is reached. At this time, the control host 4 continues to control the discharge valve 11 and the second screw feeder 3 to work, so as to realize the conveying operation of the stirred material.

[0038] Finally, it should be noted that the weighing sensor 221, control host 4, temperature-controlled electric heater 12, stirring motor 14, second screw feeder 3, corresponding control system, and external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and adapted controllers and power supplies, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0039] When using the gradient composite device for cable protection pipe of this utility model, the parameters are first set by the control host 4, the first screw feeder 2 feeds the raw material into the feed hood 20, the weighing sensor 221 on the support leg 22 weighs in real time, and after the preset value is reached, the valve 211 on the vertical pipe 21 is opened, the raw material enters the mixing tank 1, and the vibration motor 15 on the top cover 13 is started at the same time to reduce the adhesion of the raw material on the feed hood 20, the vertical pipe 21 and the inner wall of the mixing tank 1;

[0040] After the raw materials are added, valve 211 is closed, stirring motor 14 is started, driving stirring shaft 141 and stirring blades 142 to rotate, and temperature-controlled electric heater 12 outside mixing tank 1 starts heating to ensure that the raw materials are fully mixed at a suitable temperature;

[0041] After mixing, the discharge valve 11 on the discharge pipe 10 is opened, and the funnel-shaped bottom allows the raw material to smoothly enter the second spiral feeder 3, which then transports it to the molding die 30 for compound preparation.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
