Abstract
Description
Technical Field
[0001] This utility model belongs to the field of flame retardant processing, specifically relating to a quantitative mixing device for the preparation of halogen-free flame retardant materials. Background Technology
[0002] Halogen-free flame retardants are a class of flame retardant materials that do not contain halogens, produce low smoke and low toxicity during combustion, and meet environmental protection requirements. They mainly include phosphorus-based, nitrogen-based, metal hydroxide, and silicon-based flame retardant systems, and are widely used in electronics, automobiles, construction, and other fields. Halogen-free flame retardants are generally added to polymer materials such as plastics. Utilizing the material's own properties, they can absorb a large amount of heat during endothermic decomposition and dehydration, thereby achieving a flame-retardant function. Currently, halogen-free flame retardants are generally prepared by mixing them with a complexing agent and then through chemical reactions and purification. Before mixing the halogen-free flame retardant with the complexing agent, it is necessary to control the total amount of halogen-free flame retardant added to ensure that the ratio of halogen-free flame retardant to complexing agent is appropriate.
[0003] Patent document CN213885875U discloses a quantitative mixing device for preparing halogen-free flame retardant materials, including a mixing tank. Supports are fixedly connected to both sides of the mixing tank. First hydraulic push rods are fixedly connected to opposite sides of the two supports. Baffles are fixedly connected to opposite ends of the two first hydraulic push rods. A dispensing cylinder is fixedly connected to opposite sides of the two supports. Second hydraulic push rods are hinged to both sides of the mixing tank. Two weighing plates are hinged to the rear side of the mixing tank. A control valve is fixedly connected to the bottom of the mixing tank. A stirring motor is fixedly connected to the top of the mixing tank. A stirring paddle is fixedly connected to the output shaft of the stirring motor. A gravity sensor is fixedly connected to the top of the weighing plates.
[0004] The aforementioned equipment uses a first hydraulic push rod to adjust and change the position of the baffle, causing the ingredients to fall into the weighing box at the bottom. The weight is then measured using a gravity sensor at the bottom of the weighing box. However, this method has a problem: when the weight on the gravity sensor reaches the target, although the first hydraulic push rod is activated to reset the baffle and prevent further falling ingredients, some ingredients still fall and close the outlet of the mixing cylinder. This portion of the falling ingredients still enters the weighing box, directly causing the total amount of ingredients in the weighing box to exceed a specific value, which directly affects the quality of subsequent mixing ratios.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.
[0026] Depend on Figure 1 and Figure 2 As shown, it is a schematic diagram of the structure of the quantitative mixing device for preparing halogen-free flame retardant materials in this embodiment. The device includes a collection chamber 1, an output channel 2, a base 3 and a shielding cover 4. The shielding cover 4 is installed at the top opening of the collection chamber 1, the output channel 2 is installed at the bottom opening of the collection chamber 1, the base 3 is provided below the collection chamber 1, and the mixing mechanism 5 is installed in the output channel 2.
[0027] The material to be distributed is poured into the collection chamber 1. Under the action of gravity, the material flows to the bottom and enters the output channel 2. By using the dispensing mechanism 5, the total amount of material output in a single operation is controlled, so that a fixed amount of material is directly output through the output channel 2, thereby realizing the quantitative dispensing of materials.
[0028] From the appendix Figure 3 As shown, this is a schematic diagram of the dispensing mechanism 5 in this embodiment. The dispensing mechanism 5 includes a base plate 51, a drive motor 52, a linkage rod 53, a mating seat 54, and a limiting rotating block 55. The mating seat 54 is fixedly installed inside the output channel 2. A collection groove is opened inside the mating seat 54. The limiting rotating block 55 is rotatably installed in the collection groove. The linkage rod 53 is installed on the limiting rotating block 55. The linkage rod 53 passes through the side wall of the mating seat 54. The base plate 51 is installed on the side of the output channel 2. The drive motor 52 is installed on the surface of the base plate 51. The output end of the drive motor 52 is connected to the end of the linkage rod 53.
[0029] Driven by the drive motor 52, the linkage rod 53 is rotated. At this time, the limiting rotating block 55 installed in the mating seat 54 works around the linkage rod 53 as the axis. When the material inside the collection chamber 1 flows into the groove of the limiting rotating block 55, the limiting rotating block 55 drives this part of the material to rotate. The side wall of the limiting rotating block 55 is attached to the inner wall of the collection groove in the mating seat 54 to remove excess material and ensure that the total amount of material output by the limiting rotating block 55 in a single batch is the same as the volume of the self-designed groove in the limiting rotating block 55.
[0030] From the appendix Figure 4 As shown, this is a structural schematic diagram of the anti-blocking mechanism 6 in this embodiment. The anti-blocking mechanism 6 includes a side plate 61, a feeding component 62, a first bevel gear set 63, and a second bevel gear set 64. The side plates 61 are symmetrically installed inside the collection chamber 1, and the feeding component 62 is installed between the side plates 61. A stirring block is installed at one end of the feeding component 62, and a first bevel gear is installed at the other end. A second bevel gear set 64 is installed on the side of the collection chamber 1, and a first bevel gear set 63 is meshed with one end of the second bevel gear set 64. The first bevel gear set 63 is meshed with the first bevel gear. A second bevel gear is installed outside the linkage rod 53, and the second bevel gear meshes with the second bevel gear set 64. Both the first bevel gear set 63 and the second bevel gear set 64 consist of two sets of bevel gears and a linkage shaft, with the two sets of bevel gears symmetrically arranged at both ends of the linkage shaft.
[0031] When the linkage 53 rotates during use, the second bevel gear meshes with the bevel gear in the second bevel gear set 64, causing the second bevel gear set 64 to drive the first bevel gear set 63 to rotate as a whole. In conjunction with the first bevel gear, it provides power for the rotation of the feeding component 62 as a whole. When the feeding component 62 rotates inside the collection bin 1, it conveys the material inside the collection bin 1, preventing the material from accumulating at the opening at the bottom of the collection bin 1 and causing blockage inside the collection bin 1.
[0032] From the appendix Figure 5 As shown, this is a schematic diagram of the output mechanism 7 in this embodiment. It also includes an output mechanism 7, which includes a mounting plate 71, a collection pipe 72, an inlet pipe 73, an outlet pipe 74, and a control valve 75. The output channel 2 is mounted on the side of the mounting plate 71. There are two sets of mounting plates 71. The collection pipe 72 is installed between the two sets of mounting plates 71. The top of the collection pipe 72 is connected to the inlet pipe 73. The outlet pipe 74 is installed at the bottom opening of the collection pipe 72. The control valve 75 is provided at the connection between the collection pipe 72 and the inlet pipe 73 and at the connection between the collection pipe 72 and the outlet pipe 74.
[0033] During use, the end of the inlet pipe 73 is connected to the pump body and the storage chamber of the complexing agent. Through the operation of the pump body, a certain amount of complexing agent is input into the collection pipe 72 through the inlet pipe 73. Then, the control valve 75 on the inlet pipe 73 is closed, while the control valve 75 on the outlet pipe 74 is opened, so that the certain amount of complexing agent is directly output, thereby realizing the quantitative delivery of the complexing agent.
[0034] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
