Description

Technical Field

[0001] The invention relates to the technical field of waterproof coatings, in particular to a raw material proportioning device for an exposed water-based waterproof coating. Background Art

[0002] Polymer cement-based waterproof coating is a two-component waterproof coating composed of a liquid material formed by an optimized combination of synthetic high molecular polymer emulsion and various additives and a matching powder material. It is a waterproof material that has both the high elasticity of synthetic high molecular polymer materials and the good durability of inorganic materials. Cement polymer waterproof coating is a flexible waterproof coating, that is, film waterproof. Composite waterproof coating and cement polymer waterproof coating are the same material.

[0003] When the existing stirring equipment is in use, the raw materials are directly poured into the liquid for stirring, which easily causes the raw materials to form lumps and cannot be mixed with other substances in time, causing the proportion of the formed JS polymer cement-based waterproof coating to be unbalanced. Moreover, when the existing stirring equipment is in use, after the waterproof coating is discharged, the residual coating is likely to adhere to the inner wall of the stirring equipment. Manual cleaning is time-consuming and laborious and the effect is not good. Moreover, if it cannot be cleaned in time, it will cause the coating to condense on the inner wall, which is more difficult to clean.

[0004] In order to overcome the above defects, the prior art (publication number: CN114288910A, Chinese patent with application date of 2022-01-13) discloses a JS polymer cement-based waterproof coating stirring device with raw material proportioning function, which relates to the technical field of waterproof coating processing equipment, and solves the problem that the raw materials are easily agglomerated when poured directly into the liquid when the existing stirring equipment is used, including a main body, a mixing trough and a vertical, the top plate is installed on the top of the main body through a connecting rod; the top of the batching trough is provided with a groove, and the batching trough is installed at the bottom of the top plate; the slot is arranged at the bottom of the batching trough, and a card is installed inside the card slot inside the slot; the chute is arranged on the outside of the rotating rod, and the connecting plate outside the chute is installed on the inside of the scraper; the mixing trough is arranged on the top of the main body, and the mixing trough is arranged at the bottom of the batching trough, and the inner plate inside the mixing trough is installed inside the rotating rod through a spring; the vertical trough is a T-shaped structure, and the vertical trough is arranged on the inner side of the main body. The raw materials are mixed and stirred by using the mixing trough, so that the raw materials are evenly added to the stirring device.

[0005] Although the existing design can solve the above problems, the design is too simple when stirring is required, and cannot achieve a good fusion effect of the internal mixed materials, resulting in poor use effect and cannot work well. In addition, the existing design is too wasteful in the discharge work after mixing. Many residual mixtures adhere to the inner wall and cannot be discharged well, which will lead to the subsequent mixing effect being deteriorated and the waste of existing materials. The design is not practical enough and the mixing method is too single, which is insufficient for the mixing effect of the coating. Summary of the invention

[0006] The object of the present invention is to provide a raw material proportioning equipment for an exposed water-based waterproof coating, so as to solve the problem proposed in the above background technology that the design is too simple when stirring is required, and a good fusion effect of the internal mixed materials cannot be achieved, resulting in poor use effect and inability to work well.

[0008] Furthermore, the diameters of the first fixed gear, the second fixed gear and the third fixed gear gradually decrease;

[0009] The first gear bar, the second gear bar and the third gear bar are all fixed to the side surface of the support plate by engaging with the support frame bolts.

[0010] Furthermore, the inner surface of the proportioning mixing barrel is tightly fitted with the outer surface of the inner wall cleaning plate, and a central driving rod is installed at the center position of the first fixed gear, the rotation trajectory of the connecting transmission rod contacts the fixed transmission rod, and a top cleaning plate is installed above the fixed transmission rod, and a cleaning sliding groove is installed on the lower surface.

[0011] Furthermore, a return spring is installed on the outer surface of the semicircular buffer rod, and the front end of the return spring is in contact with the surface of the abutment support plate, sliding limit blocks are installed on the left and right sides of the proportioning mixing barrel, and a limited movable plate is installed on the outer surface of the sliding limit block, a sliding inner groove is opened inside the limited movable plate, and the sliding limit block slides along the internal track of the sliding inner groove.

[0012] Furthermore, a feed port is provided on the top of the proportioning and mixing barrel, and a limit movable plate is fixedly installed above the mounting base, and a hollow transmission rod is fixedly connected to the outside of the proportioning and mixing barrel by rotating the inside of the connecting rod to form a transmission structure.

[0013] Furthermore, the upper surface of the fixed turntable contacts with the interior of the hollow transmission rod to form a sliding structure, and the front end of the semicircular buffer rod is designed to be semicircular, and the front end of the return spring contacts with the outer surface of the resistance support plate to form an elastic structure, and the semicircular buffer rod is slidably installed inside the resistance support plate.

[0014] Furthermore, the fixed circular plate is integrally designed with the connecting transmission rod and the inner wall cleaning plate, the fixed transmission rod is integrally designed with the top cleaning plate, and the cleaning sliding groove is fixedly installed inside the proportioning and mixing barrel, and the upper and lower side surfaces of the top cleaning plate fit into the gap between the proportioning and mixing barrel and the cleaning sliding groove.

[0015] Furthermore, a stirring and mixing plate is installed on the outer surface of the central driving rod, and three groups of stirring and mixing plates are installed equidistantly on the outer surface of the central driving rod, and the fixed circular plate is fixedly connected to the inner surface of the inner wall cleaning plate by connecting the end of the transmission rod to form a transmission structure.

[0016] Furthermore, the inner surface of the mixing barrel contacts the outer surface of the inner wall cleaning plate to form a sliding structure.

[0017] Furthermore, the outer surface of the sliding limit block contacts the inner surface of the sliding inner groove to form a sliding structure, and two groups of the sliding limit block and the sliding inner groove are installed symmetrically about the center point of the proportioning mixing barrel.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: when the raw material proportioning equipment of the exposed water-based waterproof coating needs to stir the coating inside the proportioning and mixing barrel, the driving motor is first started to work, and the driving motor drives the hollow transmission rod to slide continuously through the fixed turntable, and then the hollow transmission rod makes the proportioning and mixing barrel slide horizontally under the constraint of the limit moving plate, and in this process, the coating inside the proportioning and mixing barrel swings back and forth to complete the preliminary mixing;

[0019] Furthermore, when the mixing barrel is swinging backward, it contacts the semicircular buffer rod. As the semicircular buffer rod is squeezed backward, the semicircular buffer rod passes through the inside of the support plate and the return spring is also compressed synchronously, so that the mixing process inside the mixing barrel is buffered, and the paint inside the mixing barrel is stirred under the elastic force of the return spring, so that the fusion effect is better, and the waterproof performance is improved in the later use;

[0020] Furthermore, when the paint is almost discharged, the first gear is rotated to drive the first fixed gear to start moving. The first fixed gear drives the inner wall cleaning plate through the connecting transmission rod, so that the inner wall cleaning plate slides closely against the inside of the proportioning and mixing barrel, so that the paint on the inner wall is discharged more cleanly, without generating waste in the proportioning process, and without causing the remaining paint to pollute and affect the raw materials that need to be fused next time. When the connecting transmission rod moves, the top cleaning plate fixed to it is driven by the fixed transmission rod. After being driven, the top cleaning plate slides along the inside of the cleaning sliding groove close to the top of the proportioning and mixing barrel, so that the cleaning work is more perfect.

[0021] Furthermore, when the proportioning mixing barrel moves back and forth, transmission can be carried out between the gear bars and the gears, thereby synchronously driving the central drive rod to rotate. This design can reduce the number of motors required, reduce equipment costs and operating energy consumption. At the same time, the gears are provided with multiple different sizes. When facing different amounts of paint or different types of materials, gears of different sizes can be selected, thereby changing the stirring speed, and completing more efficient mixing work according to the actual situation of the paint.

[0035] Example 1: Please refer to Figure 1-Figure 6The present invention provides the following technical solution: a raw material proportioning device for an exposed water-based waterproof coating, comprising a mounting base 1, a fixed mounting frame 2 and a stirring and mixing plate 21. A fixed mounting frame 2 is installed on the lower surface of the mounting base 1, and a driving motor 3 is installed above the fixed mounting frame 2, a fixed turntable 4 is installed at the output end of the driving motor 3, and a sliding transmission mechanism for reciprocating the proportioning mixing barrel 7 is installed above the fixed turntable 4, the sliding transmission mechanism includes a hollow transmission rod 5, and the hollow transmission rod 5 is a hollow design, the hollow transmission rod 5 is slidably installed above the fixed turntable 4, and a rotating connecting rod 6 is installed at the end of the hollow transmission rod 5, the front end of the rotating connecting rod 6 is rotatably installed at the end of the hollow transmission rod 5, and a proportioning mixing barrel 7 is installed inside the rotating connecting rod 6, a resistance support plate 13 is installed on the back of the proportioning mixing barrel 7, and a semicircular buffer rod 8 is installed inside the resistance support plate 13, and a first fixed gear 15, a second fixed gear 27 and a third fixed gear 28 are installed and fixed on the top of the central driving rod 20 in sequence, and the first fixed gear 15, the second fixed gear 27 and the third fixed gear 28 are meshed and connected with a first gear bar 16, a second gear bar and a third gear bar 26 in sequence.

[0036] like Figure 2 , Figure 6 , Figure 4 The technical solution shown, in order to solve the problem that the existing design of the coating mixing design is too complicated and inconvenient to use and maintain, discloses: a return spring 9 is installed on the outer surface of the semicircular buffer rod 8, and the front end of the return spring 9 is in contact with the surface of the abutting support plate 13, a sliding limit block 10 is installed on the left and right sides of the proportioning and mixing barrel 7, and a limit moving plate 11 is installed on the outer surface of the sliding limit block 10, a sliding inner groove 12 is opened inside the limit moving plate 11, and the sliding limit block 10 slides along the inner track of the sliding inner groove 12, a feed port 14 is opened on the top of the proportioning and mixing barrel 7, and the limit moving plate 11 is fixedly installed on the mounting bottom Above the seat 1, the hollow transmission rod 5 is fixedly connected to the outside of the proportioning and mixing barrel 7 by rotating the inside of the connecting rod 6 to form a transmission structure, the upper surface of the fixed turntable 4 contacts the inside of the hollow transmission rod 5 to form a sliding structure, and the front end of the semicircular buffer rod 8 is semicircular in design, and the front end of the reset spring 9 contacts the outer surface of the resistance support plate 13 to form an elastic structure, and the semicircular buffer rod 8 is slidably installed inside the resistance support plate 13, the outer surface of the sliding limit block 10 contacts the inner surface of the sliding inner groove 12 to form a sliding structure, and the sliding limit block 10 and the sliding inner groove 12 are symmetrically installed in two groups about the center point of the proportioning and mixing barrel 7.

[0037] When it is necessary to mix the paint inside the proportioning and mixing barrel 7, first start the driving motor 3 fixedly installed on the fixed mounting frame 2 to work. As the driving motor 3 is started, the fixed turntable 4 fixedly installed on the output end of the driving motor 3 is synchronously driven to rotate, and the hollow transmission rod 5 is a hollow design, so the rotation of the fixed turntable 4 drives the hollow transmission rod 5 nested above to continuously slide inside, and the rotating connecting rod 6 is driven by the hollow transmission rod 5, and the rotating connecting rod 6 rotatably installed at the end of the hollow transmission rod 5 is also synchronously driven with the movement, and the rotating connecting rod 6 drives the proportioning and mixing barrel 7 fixedly installed inside to slide, and the sliding of the proportioning and mixing barrel 7 is tracked along the sliding inner groove 12 opened in the limit moving plate 11 through the sliding limit blocks 10 symmetrically installed on the left and right sides. When the mixing barrel 7 slides backward, the back of the mixing barrel 7 contacts the front end of the semicircular buffer rod 8. Since the front end of the semicircular buffer rod 8 is semicircular in design and its diameter corresponds to that of the mixing barrel 7, the semicircular buffer rod 8 will slide backward along the inside of the contact support plate 13 after being contacted, and the return spring 9 nested on the outer surface of the contact support plate 13 will contact the contact support plate 13 during the sliding process, and the top of the return spring 9 is squeezed and contracted by the contact support plate 13, and the elastic potential energy is released after the semicircular buffer rod 8 is separated from the contact with the mixing barrel 7. This is repeated in the continuous transmission work to ensure the uniform mixing of the paint and the operation stability of the mixing barrel 7.

[0038] like Figure 1 , Figure 3 , Figure 5The technical solution shown, in order to solve the problem of waste of paint attached to the inner wall caused by the existing design, discloses: the diameters of the first fixed gear 15, the second fixed gear 27 and the third fixed gear 28 are gradually reduced, the first gear bar 16, the second gear bar and the third gear bar 26 are all fixed to the side of the support plate 13 by bolts of the embedded support frame 29, the outer surface of the inner wall cleaning plate 19 is tightly fitted with the inner surface of the proportioning mixing barrel 7, and a central driving rod 20 is installed at the center position of the first fixed gear 15, the rotation trajectory of the connecting transmission rod 18 contacts the fixed transmission rod 23, and a top cleaning plate 22 is installed above the fixed transmission rod 23, and a cleaning sliding groove 24 is installed on the lower surface, the fixed circular plate 17 is connected to the connecting transmission rod 18 and the inner wall cleaning plate 19 It is an integrated design, the fixed transmission rod 23 and the top cleaning plate 22 are integrated, and the cleaning sliding groove 24 is fixedly installed inside the proportioning and mixing barrel 7, the upper and lower side surfaces of the top cleaning plate 22 are in contact with the gap between the proportioning and mixing barrel 7 and the cleaning sliding groove 24, the outer surface of the central driving rod 20 is installed with a stirring and mixing plate 21, and three groups of stirring and mixing plates 21 are equidistantly installed on the outer surface of the central driving rod 20, and the fixed circular plate 17 is fixedly connected to the inner surface of the inner wall cleaning plate 19 by connecting the end of the transmission rod 18 to form a transmission structure, the first gear bar 16 is fixedly connected to the outside of the central driving rod 20 through the lower surface of the first fixed gear 15 to form a transmission mechanism, and the inner surface of the proportioning and mixing barrel 7 is in contact with the outer surface of the inner wall cleaning plate 19 to form a sliding structure.

[0039] When the mixing work is completed and the paint needs to be discharged, the first gear bar 16 generates meshing motion with the first gear bar 16, and the first fixed gear 15 rotates at the top of the proportioning and mixing barrel 7 as the meshing motion drives it. As the first fixed gear 15 rotates at the top of the proportioning and mixing barrel 7, the central driving rod 20 fixedly installed on the lower surface of the center position of the first fixed gear 15 is driven to rotate synchronously inside the proportioning and mixing barrel 7, and since the stirring and mixing plate 21 is fixedly installed on the outer surface of the central driving rod 20, the stirring and mixing plate 21 is also driven to rotate synchronously. At this time, the internal paint can be further mixed without discharging. After the overall mixing work is completed, the first gear bar 16 continues to rotate. While the first fixed gear 15 is driven to rotate by the first gear bar 16, the fixed circular plate 17 fixedly installed on the lower surface is also driven to rotate at the same time, and the rotation of the fixed circular plate 17 also drives the inner wall cleaning plate 19 to rotate continuously through the connecting transmission rod 18 fixedly installed on the outer surface. Since the inner wall cleaning plate 19 and the connecting transmission rod 18 are fixedly installed at the center position of the fixed circular plate 17 There are two groups, so they always keep synchronous rotation. The rotation trajectory of the inner wall cleaning plate 19 is close to the inner surface of the proportioning and mixing barrel 7, so when the inner wall cleaning plate 19 rotates, the paint inside the proportioning and mixing barrel 7 can be effectively discharged more cleanly so that the paint will not be wasted. The first fixed gear 15, the fixed circular plate 17 and the central driving rod 20 are all fixed to each other and have the same center position, which ensures the stability during rotation and ensures the mixing effect during the rotation process. A feed port 14 is opened above the mounting base 1 to facilitate the operation of feeding the mixed raw materials, and in the process of connecting the transmission rod 18 to rotate, it contacts the fixed transmission rod 23 and drives it. Since the top cleaning plate 22 is fixedly installed on the top of the fixed transmission rod 23, the top cleaning plate 22 is driven synchronously with the fixed transmission rod 23. The rotation of the top cleaning plate 22 is carried out along the inside of the cleaning sliding groove 24, and during the sliding process of the top cleaning plate 22, the upper surface is always close to the top of the inner surface of the proportioning and mixing barrel 7, so that the paint attached to the top of the inner surface of the proportioning and mixing barrel 7 is also cleaned at the same time, and the internal cleaning design is more perfect.

[0040] The interlocking support frame 29 and the abutting support plate 13 are detachably mounted, which means that the first gear bar 16, the second gear bar and the third gear bar 26 are detachably mounted. When the first fixed gear 15, the second fixed gear 27 or the third fixed gear 28 needs to be selected for transmission, the first gear bar 16, the second gear bar or the third gear bar 26 can be installed accordingly.

[0041] The first fixed gear 15, the second fixed gear 27 and the third fixed gear 28 are of different sizes, and their rotation speeds during the meshing process with the gear bar are also different. Therefore, when facing different amounts of paint or different types of materials, gears of different sizes can be selected, and the stirring speed can be changed, so that more efficient mixing work can be completed according to the actual situation of the paint.

[0042] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
