Specific embodiments

[0021] To further understand the content of the present invention, the present invention will be described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present invention rather than limiting it.

[0022] The following is combined with the attached Figures 1 - 4 This embodiment will be further described in detail.

[0023] As Figure 1 shown, a feeding device for preparing high-reflection ink in this embodiment includes a stirring kettle 100 and a feeding assembly for feeding materials into the stirring kettle 100. The feeding assembly includes a vibrating screen 110. The vibrating screen 110 feeds materials into the stirring kettle 100 through a feeding pipe. The feeding pipe includes a first vertical pipe 121 connected to the vibrating screen 110 and a second vertical pipe 122 connected to the stirring kettle 100. The first vertical pipe 121 and the second vertical pipe 122 are connected by an inclined pipe 123. An pneumatic vibrator 130 is provided outside the inclined pipe 123 and the second vertical pipe 122 through a mounting member.

[0024] In actual use of this embodiment, the stirring kettle 100 is used for stirring and mixing raw materials for subsequent preparation of high-reflection ink. Among them, the feeding assembly is used to feed raw materials into the stirring kettle 100 above the stirring kettle 100. Among them, the vibrating screen 110 can be used to vibrate and screen the raw materials. In actual use, the vibrating screen 110 adopts an existing high-frequency vibrating impurity removal screen, which is provided with a feeding port 111. The raw materials are fed into the vibrating screen 110 through the feeding port 111, so that the raw materials are dispersed, especially the raw materials in the form of solid powder are better dispersed. After being screened and impurity-removed by the vibrating screen 110, they are fed into the stirring kettle 100 through the feeding pipe, so that the raw materials can be mixed and stirred in the stirring kettle 100.

[0025] Among them, through the settings of the first vertical pipe 121, the second vertical pipe 122 and the inclined pipe 123, the feeding pipe is bent. Thus, it can better slow down the vertical delivery of raw materials into the stirring kettle 100, form splashing, and thus affect the accuracy of the formula.

[0026] Among them, through the setting of the pneumatic vibrator 130, it can form high-intensity vibration on the tube walls of the inclined tube 123 and the second vertical tube 122, thereby preventing the raw materials from accumulating at the bending part of the feeding tube, causing blockage of the feeding tube and affecting the feeding effect. Compared with the vertical delivery of the existing feeding tube, the feeding device in this embodiment can cause the feeding tube to form multi-stage vibration from top to bottom, preferably avoiding the accumulation and blockage of raw materials at the bending part of the feeding tube and affecting the feeding effect.

[0027] During the actual use of this embodiment, a vacuum negative pressure generator 140 is also provided on the inclined tube 123. Among them, the vacuum negative pressure generator 140 is installed on the inclined tube 123 and close to the position of the pneumatic vibrator 130 thereon. By using the setting of the vacuum negative pressure generator 140, it can form negative pressure in the inclined tube 123, thereby promoting the flow of raw materials in the inclined tube 123 and avoiding the accumulation and blockage of raw materials at the inclined tube 123.

[0028] In this embodiment, the feeding assembly further includes a compressed air storage tank 160 for supplying air to the pneumatic vibrator 130 and the vacuum negative pressure generator 140.

[0029] In this embodiment, the compressed air storage tank 160 is connected to the pneumatic vibrator 130 and the vacuum negative pressure generator 140 through an air pipe. The compressed air storage tank 160 is used to supply high-pressure compressed air to the pneumatic vibrator 130 and the vacuum negative pressure generator 140, and then drive the pneumatic vibrator 130 and the vacuum negative pressure generator 140 to work.

[0030] In this embodiment, a vacuum pump 150 for forming negative pressure in the stirring kettle 100 is provided outside the stirring kettle 100.

[0031] Through the structure in this embodiment, the vacuum pump 150 can generate negative pressure in the stirring kettle 100, and use the air pressure difference to put the raw materials in the feeding tube into the stirring kettle 100, preferably avoiding the accumulation and blockage of raw materials in the feeding tube, thereby improving the feeding effect of the feeding device.

[0032] During its actual use, in order to prevent the stirring kettle 100 from inhaling too many raw materials due to excessive negative pressure and affecting the accuracy of the formula, the negative pressure in the stirring kettle 100 is controlled at -0.05 to -0.1 Mpa.

[0033] Combined Figures 2 - 3 As shown, in this embodiment, the mounting member includes a first mounting member 210 and a second mounting member 220 that are spliced and held outside the inclined tube 123 or the second vertical tube 122. An installation portion 211 for installing the pneumatic vibrator 130 is formed on the outer side wall of the first mounting member 210. Corresponding ends of the first mounting member 210 and the second mounting member 220 extend outward to form matching fixing portions 230, and the matching fixing portions 230 are connected by bolts.

[0034] In this embodiment, the inner sides of the first clamping member 210 and the second clamping member 220 are both semi-circular. That is, when they are spliced together, their inner sides can cooperate to clamp outside the inclined pipe 123 or the second vertical pipe 122. Among them, the mounting portion 211 has a mounting plane facing the outside of the first clamping member 210, and the pneumatic vibrator 130 is fixed to this mounting plane by screws. Thus, the installation of the pneumatic vibrator 130 on the inclined pipe 123 and the second vertical pipe 122 can be better realized;

[0035] Among them, through the setting of the fixing portion 230, when the fixing portions 230 are cooperatively connected by bolts, the splicing between the first clamping member 210 and the second clamping member 220 can be realized, that is, the fixing of the mounting member outside the inclined pipe 123 or the second vertical pipe 122. At this time, the pneumatic vibrator 130 is installed on the mounting member, and the inner sides of the first clamping member 210 and the second clamping member 220 are attached to the outer side wall of the inclined pipe 123 or the second vertical pipe 122. When the pneumatic vibrator 130 works, it can cause the mounting member to vibrate, and the mounting member can transmit the vibration to the inclined pipe 123 or the second vertical pipe 122, thereby causing the inclined pipe 123 or the second vertical pipe 122 to vibrate and avoiding the accumulation and blockage of the raw materials inside.

[0036] Combined Figure 4 As shown, in this embodiment, a cavity 401 is provided inside the mounting portion 211. A telescopic positioning pin member is provided inside the cavity 401. Along the circumferential direction of the outer side wall of the inclined pipe 123 or the second vertical pipe 122, positioning holes (not shown in the figure) for the corresponding positioning pin members to extend into are evenly distributed. The pneumatic vibrator 130 is installed on the mounting portion 211 and is used to drive the positioning pin member to extend out of the cavity 401 and insert into the corresponding positioning hole.

[0037] Through the structure in this embodiment, when the pneumatic vibrator 130 is installed on the mounting portion 211 during actual use, it squeezes the positioning pin member to make the positioning pin member extend out of the cavity 401 and insert into the corresponding positioning hole, thereby fixing the mounting member, that is, the mounting member will not rotate along the inclined pipe 123 or the second vertical pipe 122, avoiding the rotation of the mounting member during use due to vibration, causing the air pipe to be wound and affecting the supply of compressed air from the compressed air storage tank 160 to the pneumatic vibrator 130;

[0038] Among them, a plurality of positioning holes are provided along the circumferential direction of the inclined pipe 123 or the second vertical pipe 122, so that the orientation of the mounting portion 211 on the mounting member can be adjusted, that is, the orientation of the pneumatic vibrator 130 on the mounting portion 211 can be adjusted, which is convenient for its cooperation with the compressed air storage tank 160.

[0039] In this embodiment, the opening of the cavity 401 is arranged towards the outside of the first holding member 210. A blocking ring 410 is provided at the opening of the cavity 401. The positioning pin member includes a positioning pin rod 420 slidably arranged in the cavity 401. One end of the positioning pin rod 420 penetrates through the blocking ring 410 and extends outwards, and the other end penetrates through the inner side of the first holding member 210 and extends outwards. A retaining ring 421 is provided on the side wall of the positioning pin rod 420 located in the cavity 401. A spring 430 is arranged in the cavity 401 to push the retaining ring 421 to drive one end of the positioning pin rod 420 to extend out and the other end to retract.

[0040] In this embodiment, the spring 430 is sleeved outside the positioning pin rod 420. One end of the spring 430 abuts against the retaining ring 421, and the other end abuts against the bottom wall of the cavity 401, thereby pushing the retaining ring 421 towards the blocking ring 410. In the initial state, one end of the positioning pin rod 420 penetrates through the blocking ring 410 and extends outside the mounting portion 211, and the other end retracts into the cavity 401, so as to facilitate the holding of the mounting member outside the inclined pipe 123 or the second vertical pipe 122. At the same time, when the pneumatic vibrator 130 is mounted on the mounting portion 211, one end of the positioning pin rod 420 is squeezed to retract into the cavity 401, and then the other end of the positioning pin rod 420 is driven to extend out of the inner side of the first holding member 210, so that it can be inserted into the corresponding positioning hole to position the mounting member for convenient use.

[0041] Working principle: The raw materials are put into the vibrating screen 110 from the feeding port 111. After the vibrating screen 110 vibrates and screens the raw materials, they are put into the stirring kettle 100 through the feeding pipe. During this process, the compressed air storage tank 160 is controlled to supply air to the pneumatic vibrator 130 and the vacuum negative pressure generator 140 to drive the pneumatic vibrator 130 and the vacuum negative pressure generator 140 to work. At the same time, the vacuum pump 150 is started to make the stirring kettle 100 generate negative pressure, so that the feeding pipe can generate vibration and form negative pressure, preferably avoiding the accumulation and blockage of raw materials in the feeding pipe and improving the feeding effect.

[0042] In summary, the above are only the preferred embodiments of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope covered by the patent of the present invention.
