Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of spray drying equipment, specifically a heat insulation coating spray drying equipment. Background Technology
[0002] Paint, or varnish as we commonly refer to it, is just one type. It refers to a class of liquid or solid materials that, when applied to the surface of an object, form a thin film under certain conditions to provide protection, decoration, or other special functions. Because early paints mostly used vegetable oils as their main raw material, they were also called varnishes. Now, synthetic resins have replaced vegetable oils, hence the term "coating." Furthermore, anti-corrosion and heat-insulating coatings, as the name suggests, are coatings with anti-corrosion and heat-insulating properties.
[0003] Chinese utility model CN218742703U discloses a new material surface spraying and drying device. It is designed as a rotatable drying device. The principle is that the motor drives the rotating shaft to rotate. The slider at one end of the rotating shaft is inside the slide groove, thereby driving the connecting plate to rotate together. This causes one end of the connecting plate to rotate around a circle, driving the clamping plate to rotate, which can rotate and dry the board inside the clamping plate.
[0004] However, the existing device cannot rotate 360 degrees during use, resulting in uneven drying as one side of the sheet remains at the bottom. Therefore, a spray drying device with more uniform drying properties was designed to address the aforementioned problems. Summary of the Invention
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this utility model provides a heat-insulating coating spraying and drying device, which has the advantage of better drying effect and solves the problem that existing devices cannot rotate one full turn.

[0017] Compared with the prior art, the present invention provides a heat insulation coating spraying and drying device, which has the following beneficial effects:
[0018] 1. In this drying device, the rotating component pushes the inner rod to move through the spring return, so that the clamping plate can clamp the two sides of the board.

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0028] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.
[0029] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0030] In related technologies, the principle is that a motor drives a rotating shaft to rotate, and a slider at one end of the shaft moves a connecting plate inside a groove, causing one end of the connecting plate to rotate in a circle, which in turn rotates the clamping plate, allowing the material inside the clamping plate to be dried. However, existing devices cannot rotate 360 degrees during use, resulting in uneven drying because one side of the material is always at the bottom.
[0031] To address some of the problems in related technologies, this application provides a heat-insulating coating spraying and drying device. When heat-insulating coating needs to be sprayed onto a board, firstly, the pull rod 25 is pulled to retract the inner rod 23 into the interior of the crossbar 21, simultaneously moving the clamping plate 24 away and compressing the spring 22. Then, the board is placed inside the clamping plate 24. The pull rod 25 is released, and the spring 22 rebounds, pushing the inner rod 23 out from inside the crossbar 21, pushing the clamping plate 24 closer to clamp the board. Then, the motor 27 is connected to an external power source to drive the gear 28 to rotate, meshing with the gear 26 to rotate the crossbar 21, causing the board inside the clamping plate 24 to rotate accordingly. At this time, the spraying device 12 is started to spray the heat-insulating coating onto the surface of the board. After the spraying is completed, the heating grid 13 is connected to an external power source to bake the board, accelerating the drying process.
[0032] This application is described below with reference to the accompanying drawings and specific embodiments:
[0033] This application provides a heat-insulating coating spraying and drying device, including: a box body 11 with a spraying device 12 on its top; a heating grid 13 disposed inside the box body 11; a rotating assembly 2 disposed on the box body 11, the rotating assembly 2 including: a crossbar 21 with one end penetrating through the outer wall of the box body 11 and rotatably connected to the box body 11; a spring 22 disposed inside the crossbar 21; an inner rod 23 with one end inserted into the crossbar 21 and connected to the spring 22; a clamping plate 24 disposed at one end of the inner rod 23; a pull rod 25 with one end inserted into the crossbar 21 and passing through the spring 22 and connected to the inner rod 23; a gear 26 fixedly sleeved on the outer wall of the crossbar 21; a motor 27 disposed on the outer wall of the box body 11, with its output shaft inserted into the box body 11; and a gear 28 fixedly disposed on the output shaft of the motor 27 and meshing with the gear 26.
[0034] Specifically, the spraying device 12 is actually a type of spraying machine. The principle is as follows: The spraying machine uses spraying technology, controlling the airflow to instantly reverse the air distribution device, causing the piston of the pneumatic motor to perform a stable and continuous reciprocating motion. This process pressurizes the inhaled paint, which is then delivered to the spray gun via a high-pressure hose. The spray gun instantly atomizes the paint and releases it onto the surface of the object being coated, forming a coating layer.
[0035] The principle of the heating grid 13 mainly involves converting electrical energy into heat energy through resistive materials, and then transferring the heat through heat conduction and convection. Specifically, the heating grid typically uses an electric heater, which works by generating heat through resistance wires, thereby heating the air or other media.
[0036] When it is necessary to spray heat insulation coating on the board, first pull the lever 25 to retract the inner rod 23 into the inside of the crossbar 21, while moving the clamping plate 24 away and compressing the spring 22. Then place the board inside the clamping plate 24, release the lever 25, and the spring 22 will rebound to push the inner rod 23 out from the inside of the crossbar 21, pushing the clamping plate 24 closer to clamp the board. Then connect the motor 27 to the external power supply to drive the gear 28 to rotate, and mesh with the gear 26 to drive the crossbar 21 to rotate, so that the board inside the clamping plate 24 rotates accordingly. At this time, start the spraying device 12 to spray the heat insulation coating on the surface of the board. After the spraying is completed, connect the heating grid 13 to the external power supply to bake the board and speed up the drying of the board.
[0037] In some embodiments, the spring 22 is designed as a rectangular rod, with its outer sidewall fitting against the inner sidewall of the crossbar 21.
[0038] When in use, the rectangular bar design allows the inner bar 23 to rotate more effectively when the crossbar 21 rotates.
[0039] In some embodiments, the inner sidewall of the clamping plate 24 is designed with a triangular groove shape.
[0040] The triangular groove design restricts the vertical movement of the material when clamping it, making the clamping more secure.
[0041] In some embodiments, the rotating assembly 2 further includes a tension 29 disposed at one end of the pull rod 25.
[0042] The design of the pull knob 29 makes it easy to grip and control the pull rod 25 to be pulled out from inside the crossbar 21.
[0043] In some embodiments, the rotating assembly 2 further includes a housing 291 disposed outside the gear 1 26 and the gear 2 28, and connected to the inner sidewall of the housing 11.
[0044] When in use, the housing 291 is designed to enclose gear 1 26 and gear 2 28, better protecting gear 1 26 and gear 2 28 from external interference.
[0045] In some embodiments, a clamping assembly 3 is provided on the inner side of the clamping plate 24. The clamping assembly 3 includes: a groove 31 formed on the outer side wall of the clamping plate 24; one end of a threaded rod 32 inserted into the interior of the groove 31 and rotatably connected to the groove 31; and a slider 33 slidably disposed in the interior of the groove 31 and threadedly connected to the threaded rod 32 through it.
[0046] When the plate is clamped, the threaded rod 32 can be rotated to make the threaded rod 32 threadedly connected to the slider 33, and drive the slider to slide closer inside the groove 31 until it contacts the plate, which can better restrict the position of the plate.
[0047] In some embodiments, the clamping assembly 3 further includes a knob 34 disposed at one end of the threaded rod 32.
[0048] When in use, the design of the knob 34 makes it easy to grip and control the rotation of the threaded rod 32. At the same time, the groove on the knob can increase the friction when gripping.
[0049] In some embodiments, the outer sidewall of one end of the slider 33 is in contact with the inner sidewall of the groove 31.
[0050] The design that fits snugly during use can better restrict the stable sliding of slider 33, making it less likely to wobble or rotate during sliding.
