Description

Technical Field

[0001] This utility model relates to the field of cotton processing technology, specifically to a cotton opening device for cotton processing. Background Technology

[0002] The cotton opening equipment used in cotton processing is mainly the cotton opening machine. The cotton opening machine is a type of textile machinery mainly used to perform preliminary processing on the cotton in the cotton bales. Through mechanical tearing, beating and other methods, the compressed cotton is loosened, making it smaller and looser, removing some impurities, and forming a more loose and uniform state, providing a suitable raw material basis for subsequent processes such as carding. With the continuous development and use of cotton opening machines, various kinds of cotton opening equipment have emerged, such as a cotton opening equipment for cotton processing.

[0003] Currently, cotton openers on the market mainly focus on improving mechanical cotton opening. Existing cotton openers generally consist of a cotton opener body, a cotton feeding module, rollers, and a control system. The control system activates the cotton feeding module to allow cotton to enter the cotton opener body, where it is then loosened by the rollers and finally discharged. However, high-humidity cotton is prone to entanglement on the opening rollers, leading to increased fiber damage. Furthermore, the collection box lacks insulation, causing the cotton to easily clump again after opening. Therefore, a cotton opening device is proposed that can uniformly heat the cotton, reducing the breaking strength of the cotton fibers and improving the opening efficiency. It can also keep the opened cotton warm to prevent secondary clumping. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cotton opening device for cotton processing. It has the advantages of being able to uniformly heat cotton, reducing the breaking strength of cotton fibers after heating, improving opening efficiency, and keeping the opened cotton warm to avoid secondary clumping. It solves the problems of high-humidity cotton easily entangles in the opening roller, leading to increased fiber damage rate, and the lack of insulation measures in the collection box, which makes the cotton prone to secondary clumping after opening.

[0005] To achieve the above-mentioned purpose of uniformly heating cotton, reducing the breaking strength of cotton fibers after heating, improving opening efficiency, and keeping the opened cotton warm to avoid secondary clumping, this utility model provides the following technical solution: a cotton opening device for cotton processing, including a vertical cotton opening machine, wherein a conveyor belt is fixedly installed on the right side of the vertical cotton opening machine, and a dehumidification mechanism is provided on the top of the conveyor belt.

[0006] The dehumidification mechanism includes a heating box, a PTC heater, a fixed plate, a capacitive humidity sensor 1, a hot air blower, a capacitive humidity sensor 2, a heat preservation box, and a capacitive humidity sensor 3. The heating box is fixedly installed on the top of the conveyor belt. Two PTC heaters are installed on the inner wall of the heating box. Two fixed plates are fixedly installed inside the heating box. Capacitive humidity sensors 1 are installed on the outside of both fixed plates. A hot air blower is fixedly installed inside the heating box. Capacitive humidity sensors 2 are installed on the inner wall of the vertical cotton opener. A heat preservation box is fixedly installed on the left side of the vertical cotton opener. Capacitive humidity sensors 3 are fixedly installed on the inner wall of the heat preservation box.

[0007] Furthermore, an air inlet filter is provided on the top of the heating box. The air inlet filter is located on the top of the hot air blower. By providing an air inlet filter, it is beneficial for the hot air blower to intake air and can filter out impurities.

[0008] Furthermore, a heat insulation layer is provided on the left side of the heating box, and an opening is provided on the outside of the heat insulation layer. By providing the heat insulation layer, it is beneficial to isolate the temperature inside the heating box and prevent the temperature from being conducted into the vertical cotton opener.

[0009] Furthermore, the inner wall and bottom of the insulated box are provided with an insulation layer. The insulation layer helps to keep the already loose cotton warm and prevents it from clumping again.

[0010] Furthermore, the top of the insulated box is hinged with a cover plate, and the inside of the cover plate is provided with a heat insulation plate. By setting the cover plate, it is easy to seal the insulated box and the cotton can be taken out when needed.

[0011] Furthermore, a power distribution box is provided in front of the conveyor belt, and a PLC controller is installed inside the power distribution box. By setting the PLC controller, the operation of the electronic components in this patent can be controlled.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This cotton opening equipment, equipped with a dehumidification mechanism, activates the conveyor belt via a PLC controller inside the distribution box when cotton opening is required. A capacitive humidity sensor detects the initial humidity of the cotton and connects to the PLC controller. When the moisture content exceeds 12%, a heating mode is activated. PTC heaters on the side walls and four top-mounted hot air blowers evenly heat the cotton. Capacitive humidity sensors 2 and 3 monitor the humidity of the cotton hull during and after opening, providing feedback to the PLC controller to adjust the hot air temperature. This dehumidification mechanism ensures uniform heating of the cotton, reducing fiber breaking strength and improving opening efficiency. It also keeps the opened cotton warm, preventing secondary clumping. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-5 In this embodiment, a cotton opening device for cotton processing includes a vertical cotton opener 1, a conveyor belt 2 fixedly installed on the right side of the vertical cotton opener 1, and a dehumidification mechanism 3 provided on the top of the conveyor belt 2.

[0022] The dehumidification mechanism 3 includes a heating box 301, a PTC heater 302, a fixing plate 303, a capacitive humidity sensor 304, a hot air blower 305, a capacitive humidity sensor 306, a heat preservation box 307, and a capacitive humidity sensor 308. The heating box 301 is fixedly installed on the top of the conveyor belt 2. Two PTC heaters 302 are installed on the inner wall of the heating box 301. Two fixing plates 303 are fixedly installed inside the heating box 301. Capacitive humidity sensors 304 are installed on the outside of both fixing plates 303. A hot air blower 305 is fixedly installed inside the heating box 301. A capacitive humidity sensor 306 is installed on the inner wall of the vertical cotton opener 1. A heat preservation box 307 is fixedly installed on the left side of the vertical cotton opener 1. A capacitive humidity sensor 308 is fixedly installed on the inner wall of the heat preservation box 307.

[0023] In the implementation of the case, an air inlet filter 4 is installed on the top of the heating box 301. The air inlet filter 4 is located on the top of the hot air blower 305. By setting the air inlet filter 4, it is beneficial for the hot air blower 305 to take in air and can filter out impurities. The air outlet of the hot air blower 305 is tilted at 30 degrees and points into the vertical cotton opener 1.

[0024] In the implementation of the case, capacitive humidity sensor 304, capacitive humidity sensor 306, and capacitive humidity sensor 308 can sense the humidity of cotton at different locations, so that the PLC controller can adjust the temperature of PTC heater 302. In this patent, PTC heater 302 and hot air blower 305 are heating components. The temperature of the heating components can be adjusted by the PLC controller, with an adjustment range of 40 to 80 degrees Celsius. When the humidity detection is high, it is heated to 80 degrees Celsius, and when there is slight humidity, it is heated to 40 degrees Celsius. The heating temperature is automatically adjusted according to the moisture content. After heating, the breaking strength of cotton fibers decreases and the impurity removal rate increases. The 60-degree hot air softens the wax layer on the fiber surface and reduces the winding rate of the opening roller.

[0025] In the implementation of this case, the capacitive humidity sensor of this patent is equipped with a filter screen on the outside to prevent cotton fibers from entering, which is beneficial for normal humidity monitoring.

[0026] In the case implementation, the inner wall and bottom of the insulated box 307 are equipped with an insulation layer 6. The insulation layer 6 helps to keep the already loose cotton warm and prevents it from clumping again. The side walls of the insulated box 307 are filled with a polyurethane insulation layer 6 (20 mm thick), and the temperature inside the box can be maintained at 10 degrees Celsius higher than the ambient temperature.

[0027] In the implementation of the case, a power distribution box 8 is set in front of the conveyor belt 2. The power distribution box 8 is equipped with a PLC controller. By setting the PLC controller, the operation of the electronic components in this patent can be controlled. All electronic components in this patent are electrically connected to the PLC controller through wires, so that all electronic components in this patent can be controlled by the PLC controller.

[0028] When implementing this procedure, please follow these steps:

[0029] 1) When cotton opening is required, start conveyor belt 2 first through the PLC controller inside distribution box 8;

[0030] 2) Then, the capacitive humidity sensor 304 detects the initial humidity of the cotton and connects to the PLC controller inside the distribution box 8. When the moisture content is greater than 12%, the heating mode is activated, and the cotton is heated evenly by the PTC heater 302 on the side wall and the four top hot air blowers 305.

[0031] 3) Then, the humidity of the cotton hull during and after opening is monitored in real time by capacitive humidity sensor 2 (306) and capacitive humidity sensor 3 (308).

[0032] 4) Finally, the PLC controller adjusts the hot air temperature based on the feedback.

[0033] In summary, this cotton opening equipment, through the installation of a dehumidification mechanism 3, activates the conveyor belt 2 via the PLC controller inside the distribution box 8 when cotton opening is required. A capacitive humidity sensor 304 detects the initial humidity of the cotton and connects to the PLC controller inside the distribution box 8. When the moisture content exceeds 12%, the heating mode is activated. The PTC heater 302 on the side wall and four top hot air blowers 305 uniformly heat the cotton. Furthermore, capacitive humidity sensors 306 and 308 monitor the humidity of the cotton shell during and after opening in real time, providing feedback to the PLC controller to adjust the hot air temperature. This dehumidification mechanism 3 ensures uniform heating of the cotton, reducing the breaking strength of the cotton fibers and improving the opening efficiency. It also keeps the opened cotton warm, preventing secondary clumping.
