Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of titanium dioxide production equipment and relates to a self-made titanium dioxide bag receiving device special for chemical fiber masterbatch. Background Art
[0002] Titanium dioxide for chemical fiber masterbatch is a special titanium dioxide used in the production of chemical fiber masterbatch. Its main function is to provide white pigment and matting effect for chemical fiber masterbatch. It has excellent optical properties and pigment properties. It is a white powder with the advantages of small particle size, high whiteness, high decolorizing power and good hue.
[0003] In the production process of titanium dioxide for chemical fiber masterbatch, there are many problems in the powder receiving link after the original crushing section. First of all, the powder receiving method is extremely primitive. It is necessary to manually place a ton bag of materials at the mouth of the powder receiving tube, and manually operate the switch of the silo wall vibrator, motor and powder feeder to control the material transportation. The whole process relies on manual fine-tuning, which is not only time-consuming and labor-intensive, but also difficult to ensure the stability of the weight in the ton bag.
[0004] In addition, due to the low fineness of the material, dust is easily raised during the falling process. Although the personnel are equipped with protective equipment, it is still unable to effectively prevent the dust from being dispersed in the air. This not only poses a threat to the health of the operators, but also causes certain pollution to the environment.
[0005] Therefore, it is necessary to improve the prior art to overcome the defects in the prior art. Utility Model Content

During the unloading process, the actuator of the hook assembly repeatedly moves up and down, so that the powder can flow evenly into the ton bag. When the unloading is completed, the ton bag is removed from the hook assembly, and the ton bag is placed on the pallet and transported away by a forklift.
[0010] As a further improvement of an embodiment of the utility model, it also includes a programmable logic controller, and the discharge valve motor, weighing pressure sensor, driving component on the hook assembly, and the motor are all electrically connected to the programmable logic controller.
[0011] As a further improvement of an embodiment of the utility model, the hook assembly includes a plurality of inverted hook cylinders, a hook is provided on the piston of the hook cylinder, and the hanging ear on the ton bag is provided on the hook.
[0012] As a further improvement of one embodiment of the utility model, the bag mouth clamping mechanism includes a plurality of clamping cylinders circumferentially distributed on the periphery of the sleeve, and a pressure plate is provided on the piston of the clamping cylinder. When the clamping cylinder is in the expanded state, the pressure plate is crimped on the sleeve at the upper edge of the discharge port.
[0013] As a further improvement of an embodiment of the utility model, it further includes a control console, on which an emergency stop button and an alarm indicator light electrically connected to the programmable logic controller are provided.

[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.
[0029] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention. Example
[0030] See also Figure 1-Figure 6 As shown, a self-made titanium dioxide bag receiving device for chemical fiber masterbatch includes a feeder 3 corresponding to the outlet of the silo 1. The feeder 3 is a screw feeder, and its power source is an electric motor 31. The screw feeder is located above and connected to the outlet of the silo 1, so that the powder in the silo 1 falls into the screw feeder 3. Under the drive of the electric motor 31, the material entering the feeder 3 moves forward to the sleeve 6. In order to control the feeding of the silo 1, a discharge valve 5 is provided at the outlet of the silo 1. The opening of the discharge valve 5 is controlled by the discharge valve motor driven by the frequency converter to realize the quantitative delivery of the silo 1.
[0031] Through the above structural design, the outlet of the sleeve 6 is the discharge port of the whole device. Figure 1 It can be seen that the sleeve 6 has a vertical channel, the lower end opening of which is the outlet of the sleeve, and the powder in the silo 1 falls from the outlet.
[0032] A hook assembly for hanging the ton bag 8 is arranged outside the sleeve 6. Specifically, the hook assembly includes a plurality of inverted hook cylinders 4 (in this embodiment, the number of hook cylinders 4 is four, circumferentially distributed at four positions of the sleeve 6), a hook is arranged on the piston of the hook cylinder 4, and the hanging ear on the ton bag 8 is arranged on the above hook. When the ton bag 8 is hung on the hook, the upward and downward telescopic movement of the hook cylinder 4 can drive the ton bag 8 to be pulled, so that the powder can flow into the ton bag 8 evenly.
[0033] The bag mouth and the discharge port of the ton bag 8 are clamped by the bag mouth clamping mechanism, so that the powder falling from the sleeve 6 directly enters the ton bag 8, avoiding the powder from scattering and affecting the on-site environment and personnel health. Specifically, the bag mouth clamping mechanism includes a plurality of clamping cylinders 7 circumferentially distributed on the periphery of the sleeve 6, and a pressure plate is provided on the piston of the clamping cylinder 7. One side of the pressure plate is a crimping surface, which is a contoured design and adapted to the clamping part on the sleeve 6 (there are at least two clamping cylinders 7, which are pressed on the sleeve from different directions). When the clamping cylinder 7 is in the expanded state, the pressure plate is pressed on the sleeve at the upper edge of the discharge port; when the clamping cylinder 7 is in the contracted state, the pressure plate is separated from the sleeve. When in use, the staff sets the bag mouth of the bag 8 on the sleeve 6 in advance, and then starts the clamping cylinder 7 to press the bag mouth of the bag 8 on the sleeve 6, completing the bag mouth clamping and fixing operation of the ton bag 8.
[0034] A tray 9 is provided below the sleeve 6 for placing the ton bag 8, and a weighing pressure sensor 10 linked to the discharge valve motor is provided below the tray 9. The weighing pressure sensor 10 can sense the weight change of the ton bag 8 on the tray 9 in real time. When its weight reaches the set maximum threshold, the discharge valve motor closes the discharge valve 5, and the feeder 3 stops feeding, completing the quantitative discharge operation. The weighing pressure sensor 10 is electrically connected to the junction box 11.
[0035] A silo wall vibrator 2 is provided on the silo 1. When the feeder 3 is running and the weight of the ton bag 8 detected by the weight pressure sensor 10 does not increase within the set time of material unloading, the silo wall vibrator 2 is started to assist unloading. Of course, the vibration can also be turned on at a fixed time to assist unloading according to actual conditions.
[0036] The device of this embodiment adopts a PLC (programmable logic controller) as a controller. The above-mentioned discharge valve motor, weighing pressure sensor 10, driving component (hook cylinder 4) on the hook assembly, motor 31, warehouse wall vibrator 2, and sensor are all electrically connected to the programmable logic controller, wherein the PLC is electrically connected to the millivolt converter through an analog-to-digital converter, and the millivolt converter is electrically connected to the weighing pressure sensor 10.
[0037] Furthermore, in order to guide on-site personnel to operate, it also includes a control console, on which are provided an emergency stop button, an alarm indicator light, a bag clamping start button and a touch screen, which are electrically connected to the programmable logic controller. The touch screen is used as a human-machine interface, and the alarm indicators respectively indicate discharge, full material and fault, so that on-site personnel can quickly understand the use of the device.
[0038] Before starting the device, the weight of each bag is preset and the ton bag is hung on the hooks at the four corners of the device. The tray 9 is placed below, the opening is aligned with the sleeve, and the bag opening clamping start button is pressed. The clamping cylinder 7 clamps the bag opening and the discharge port. After clamping, the system starts the discharge valve motor to start unloading. The discharge valve motor is driven by the frequency converter. The unloading speed is collected by the PLC. The real-time measurement value of the weighing pressure sensor is calculated by the controller and then the control signal is output to adjust the unloading speed. When the weighing pressure sensor detects that the weight reaches the set value, the unloading is stopped. During the unloading process, the hook cylinder 4 repeatedly moves up and down so that the powder can flow evenly into the ton bag 8. After unloading is completed, the hook cylinder 4 falls, and the ton bag is placed on the tray 9 and transported away by a forklift.
[0039] This utility model is a self-made bag receiving device for titanium dioxide powder for chemical fiber masterbatch. The action can be controlled by a touch screen. The weight of powder in the ton bag can be displayed in real time on the display screen. The device can realize actions such as bag mouth holding, ton bag lifting, sealing unloading, and vibration unloading. By using PLC to connect the weighing pressure sensor to realize quantitative control of materials, the manual repeated verification of adding and subtracting materials is reduced, the intensity of manual operation is reduced, and the weight accuracy of bagged materials is improved. At the same time, after the transformation, the personnel are changed from operators to supervisors. The change of roles reduces the contact between personnel and dust and protects the health of employees.
