Abstract
Description
Technical Field
[0001] The present application relates to the technical field of self-spraying paint, and in particular to a glass bead screening device and self-spraying paint production equipment. Background Art
[0002] Spray paint usually consists of an aerosol can, an aerosol valve, contents (paint) and a propellant. It is a kind of paint that is processed by a special method and then filled with high pressure for easy spraying. Since paint is a very thick liquid, if it is not shaken evenly before use, it may cause clogging, incomplete spraying, insufficient covering power, paint particles, etc. Therefore, spray paint manufacturers will add some spherical beads in the can to even out the material when shaking.
[0003] In order to achieve better use effect and cost-effectiveness, most manufacturers choose to use glass as the material of spherical beads when producing self-spray paint. After the production of glass beads, there may be problems such as broken glass beads, uneven sizes, dirt, and impurities on the surface. If the glass beads are put into use directly after production, it will not only directly pollute the liquid, but also seriously may cause the nozzle to be blocked due to glass fragments and impurities, and the product cannot be sprayed directly or cannot be sprayed completely.
[0004] At present, glass beads are usually selected manually, so as to select glass beads that meet the requirements for the production of self-spraying paint. However, the manual selection of glass beads is not only inefficient, but also increases the production cost of self-spraying paint. Summary of the invention
[0005] Based on this, it is necessary to provide a glass bead screening device to address the problem that the manual selection of glass beads is not only inefficient but also increases the production cost of spray paint.

[0012] In one of the embodiments, the blanking piece further includes a discharge port interconnected with the blanking opening, the cross-sectional area of the blanking piece gradually decreases from the discharge port to the blanking opening, and the cross-section is perpendicular to the direction of gravity.
[0013] In one embodiment, the screening element is further provided with a second opening, and the second opening penetrates to a side wall of the second screening space.

[0019] In one embodiment, the spray paint production equipment further includes a cleaning device, and the cleaning device is used to clean the glass beads.
[0020] In the above-mentioned glass bead screening device, the glass beads that have been manufactured but not screened enter the first screening space of the screening element from the opening, and the glass beads with a diameter larger than the first screening hole cannot enter the first screening hole, thereby remaining in the first screening space, while the glass beads with a diameter smaller than the first screening hole will pass through the first screening hole and leave the first screening space from the bottom of the first screening space to enter the second screening space, thereby screening out the oversized glass beads through the first screening space.
[0021] Furthermore, among the glass beads entering the second screening space, the glass beads with a diameter smaller than the second screening hole will leave the screening element through the second screening hole, while the glass beads with a diameter larger than the second screening hole will remain in the second screening space.

That is, the size of the glass beads in the second screening space will meet the diameter requirement for production. The glass beads in the second screening space can be taken out and directly used for filling in the spray paint production line.

If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.
[0036] See also Figure 1 and Figure 2 The glass bead screening device provided in one embodiment of the present application includes a support frame 10 and a screening member 20 disposed on the support frame 10. A first screening space 21 and a second screening space 26 are formed inside the screening member 20. In the direction of gravity, the first screening space 21 is located above the second screening space 26. A first screening hole 22 communicating with the second screening space 26 is provided on the bottom wall of the first screening space 21. An opening 23 communicating with the first screening space 21 is provided on the top of the screening member 20. A second screening hole communicating with the inside of the second screening space 26 is provided on the bottom wall of the second screening space 26. The diameter of the second screening hole is smaller than that of the first screening hole 22.
[0037] In actual use, the glass beads that have been manufactured but not screened enter the first screening space 21 of the screening element 20 from the opening 23, and the glass beads with a diameter larger than the first screening hole 22 cannot enter the first screening hole 22, thereby remaining in the first screening space 21, while the glass beads with a diameter smaller than the first screening hole 22 will pass through the first screening hole 22 and leave the first screening space 21 from the bottom of the first screening space 21 to enter the second screening space 26, thereby screening out the oversized glass beads through the first screening space 21.
[0038] Furthermore, among the glass beads entering the second screening space 26, the glass beads with a diameter smaller than the second screening hole will leave the screening element 20 through the second screening hole, while the glass beads with a diameter larger than the second screening hole will remain in the second screening space 26. Since the glass beads entering the second screening space 26 have been screened by the first screening holes 22 in the first screening space 21, the diameter of the glass beads remaining in the second screening space 26 will be smaller than the diameter of the first screening holes 22 and larger than the diameter of the second screening holes. That is, the size of the glass beads in the second screening space 26 will meet the diameter requirement for production. The glass beads in the second screening space 26 can be taken out and directly used for filling in the spray paint production line. Compared with the manual screening method, the above-mentioned glass bead screening device greatly improves the speed of glass bead screening and reduces the production cost of spray paint.
[0039] Optionally, the diameter of the first screening hole 22 is 14.5 mm, and the diameter of the second screening hole is 13 mm. Glass beads with a diameter greater than 14.5 mm will be screened by the first screening hole 22, and glass beads with a diameter less than 13 mm will be screened by the second screening hole. Finally, the glass beads with a diameter in the range of 13 mm-14.5 mm can be directly sent to the paint production line for filling.
[0040] In actual use, the second screening space 26 is used to screen qualified glass beads, while the first screening space 21 is used to screen unqualified glass beads. The qualified glass beads are collected and used for filling in the spray paint production line, and the unqualified glass beads can also be collected and returned to the glass bead manufacturer, thereby recycling the unqualified glass beads and saving costs.
[0041] In order to facilitate the collection of glass beads in the first screening space 21, in some embodiments of the present application, a first opening 24 is opened on the screening element 20, and the first opening 24 penetrates to the side wall of the first screening space 21. After the glass beads are screened in the first screening space 21, the glass beads remaining in the first screening space 21 can leave the first screening space 21 through the first opening 24, thereby collecting unqualified glass beads in the first screening space 21.
[0042] In order to facilitate the collection of glass beads in the second screening space 26, in some embodiments of the present application, a second opening 25 is opened on the screening element 20, and the second opening 25 penetrates to the side wall of the second screening space 26. After the unqualified glass beads pass through the first screening holes 22 and the second screening holes, the qualified glass beads will remain in the second screening space 26. The glass beads remaining in the second screening space 26 can leave the second screening space 26 through the second opening 25, thereby collecting the qualified glass beads in the first screening space 21.
[0043] In addition to the unqualified glass beads remaining in the first screening space 21, there are also glass beads leaving the second screening space 26 through the second screening holes. In order to collect the glass beads passing through the second screening holes, a collecting tube or other collecting component can be placed directly under the second screening holes. However, since the screening component 20 is installed on the support frame 10, the space under the second screening hole will be occupied by the support frame 10, and the collecting component cannot be placed directly under the second screening hole.
[0044] To this end, in some embodiments of the present application, the glass bead screening device further includes a guide member 40, which is mounted on the support frame 10. The guide member 40 is mounted on the support frame 10, and a guide slope 41 is formed on the guide member 40. The guide slope 41 is inclined relative to the horizontal direction and intersects with the gravity direction. In the gravity direction, the guide slope 41 is located below the second screening hole, and the high point of the guide slope 41 is close to the second screening hole.
[0045] In actual use, a collecting piece (not shown) is placed at the lower part of the guide slope 41. After the glass beads are screened in the second screening space 26, unqualified glass beads will leave the second screening space 26 through the second screening holes and finally fall onto the guide slope 41. Under the action of the guide slope 41, they fall into the collecting piece, thereby collecting the unqualified glass beads through the collecting piece. The unqualified glass beads can be guided by the guide slope 41 to fall onto the collecting piece located outside the support frame 10.
[0046] In some embodiments of the present application, the glass screening device also includes a vibration generator, which is installed on the screening element 20. The vibration generated by the vibration generator will act on the screening element 20, causing the screening element 20 to vibrate. Under the action of the vibration of the screening element 20, the glass beads will roll in the first screening space 21 or the second screening space 26. During the rolling process, the glass beads will pass through the first screening hole 22 or the second screening hole, thereby screening the glass beads.
[0047] In some embodiments, the glass bead screening device also includes a vibration damper 42, which is arranged between the screening element 20 and the support frame 10, so that when the vibration generator causes the screening element 20 to vibrate, the vibration damper 42 can reduce the vibration transmitted from the screening element 20 to the support frame 10, thereby improving the service life of the support frame 10.
[0048] Optionally, the vibration damper 42 is a spring, and both ends of the spring are respectively in contact with the screening element 20 and the supporting element. When the screening element 20 vibrates, the spring is compressed or stretched, thereby absorbing the vibration of the screening element 20 through the spring. In some other embodiments, the vibration damper 42 can also be a rubber element.
[0049] In some embodiments of the present application, the glass bead screening device also includes a discharge piece 30, which has a discharge port 31. The discharge port 31 is located at an end of the screening piece 20 away from the first opening 24, and the discharge port 31 faces the opening 23. The first screening hole 22 is located between the discharge port 31 and the first opening 24. The blanking piece 30 is used to deliver the glass beads into the screening piece 20. Specifically, after the glass beads are poured into the blanking piece 30, the glass beads fall into the open opening 23 through the blanking port 31 of the blanking piece 30, and finally enter the first screening space 21. After that, the screening piece 20 will roll in the first screening space 21 under the action of the vibration generator. Since the first screening hole 22 is located between the blanking port 31 and the first opening 24, the glass beads will first pass through the first screening hole 22 and then enter the first opening 24 during the rolling process in the first screening space 21. When the glass beads pass through the first screening hole 22, the glass beads with a diameter smaller than the first screening hole 22 will fall into the first screening hole 22, and the remaining glass beads with a diameter larger than the first screening hole 22 will pass through the first screening hole 22 and finally fall into the first opening 24.
[0050] In some embodiments, in order to feed the glass beads into the blanking piece 30, the blanking piece 30 also includes a discharge port 32 interconnected with the discharge opening 31, and the cross-sectional area of the blanking piece 30 gradually decreases from the discharge port 32 to the discharge port 31, and the cross-section is perpendicular to the direction of gravity. That is to say, the discharge port 32 of the blanking piece 30 is larger, while the discharge port 31 is smaller. The larger discharge port 32 can facilitate the one-time placement of glass beads at an angle, while the smaller discharge port 31 can control the number of glass beads coming out of the discharge port 31, thereby controlling the number of glass beads falling into the open mouth 23, avoiding a large number of glass beads falling into the first screening space 21, resulting in some qualified glass beads failing to enter the first screening hole 22 and directly entering the first opening 24, causing waste of glass beads.
[0051] The present application also provides a spray paint production equipment, including a glass bead screening device as in any of the above embodiments. The size of the glass beads screened by the above glass bead screening device can meet the diameter requirements for the spray paint production. Compared with the manual screening method, the above glass bead screening device greatly improves the speed of glass bead screening and reduces the production cost of the spray paint.
[0052] In some embodiments of the present application, refer to Figure 2The spray paint production equipment also includes a cleaning device 50, which is used to clean glass beads. The cleaning device 50 is mainly used to remove oil stains and impurities on the surface of the glass beads. Specifically, the cleaning device 50 includes a cleaning bucket 51 and a colander 52. The cleaning bucket 51 is filled with an environmentally friendly organic solvent that is easily volatile. The glass beads are placed in the cleaning bucket 51, and the organic solvent covers the glass beads. The glass beads are stirred back and forth by the colander 52 to make the glass beads flip until the oil stains and impurities on the surface of the glass beads are removed, and then the glass beads in the cleaning bucket 51 are scooped out by the colander 52 into the discharge port 32 of the discharge part 30.
[0053] The above-mentioned glass bead screening device has at least the following advantages:
[0054] The manufactured but unscreened glass beads enter the first screening space 21 of the screening element 20 from the opening 23, and the glass beads with a diameter larger than the first screening hole 22 cannot enter the first screening hole 22, and thus remain in the first screening space 21, while the glass beads with a diameter smaller than the first screening hole 22 will pass through the first screening hole 22 and leave the first screening space 21 from the bottom of the first screening space 21 to enter the second screening space 26, thereby screening out the oversized glass beads through the first screening space 21.
[0055] Furthermore, among the glass beads entering the second screening space 26, the glass beads with a diameter smaller than the second screening hole will leave the screening element 20 through the second screening hole, while the glass beads with a diameter larger than the second screening hole will remain in the second screening space 26. Since the glass beads entering the second screening space 26 have been screened by the first screening holes 22 on the first screening space 21, the diameter of the glass beads remaining in the second screening space 26 will be smaller than the diameter of the first screening holes 22 and larger than the diameter of the second screening holes. That is, the size of the glass beads in the second screening space 26 will meet the diameter requirement for production. The glass beads in the second screening space 26 can be taken out and directly used for filling in the self-spraying paint production line. Compared with the manual screening method, the above-mentioned glass bead screening device greatly improves the speed of glass bead screening and reduces the production cost of self-spraying paint.
[0056] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0057] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
