Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, and in particular to a constant temperature chamber for feeding materials in a spraying machine. Background Technology

[0002] In modern industrial manufacturing, spraying is a crucial surface treatment process, and the final coating quality directly affects the product's appearance and protective performance. The coatings used in spraying, such as paints, are extremely sensitive to environmental temperature in terms of their viscosity, leveling properties, and other physical characteristics. Even slight temperature fluctuations can cause significant changes in the physical properties of the coating, thus affecting the stability of the spraying process and the final coating effect, potentially leading to surface defects such as sagging and orange peel.

[0003] To ensure the stability and consistency of coating quality, the coating machine's feeding system is typically placed in a constant-temperature chamber that provides a stable environment. This chamber regulates the internal temperature through a built-in temperature control system and ventilation mechanism, creating ideal environmental conditions for the storage and transport of coatings.

[0004] Existing constant temperature room ventilation systems often employ simple baffles or multi-speed fans to regulate airflow. This method is rather coarse and struggles to achieve linear, precise control of airflow. When fine adjustments to the internal temperature of the constant temperature room are needed, this crude approach either leads to excessive air intake, causing a sudden drop in temperature and frequent heating compensation, resulting in energy waste and temperature oscillations; or it reacts sluggishly, failing to respond promptly to temperature control commands, causing the internal temperature to deviate from the set value for extended periods. The fundamental reason is that these ventilation systems lack a transmission structure capable of translating control signals into smooth, continuous mechanical actions, thereby enabling fine-tuning of the air intake.

[0005] This inadequacy in airflow control directly limits the ability of the constant temperature chamber to maintain a high-precision constant temperature environment, making it difficult to meet the stringent requirements of high-end spraying processes for the stability of the material supply environment.

[0006] Therefore, this utility model proposes a constant temperature chamber for feeding materials in a spraying machine to overcome the shortcomings of the prior art. Utility Model Content

[0007] To overcome the above shortcomings, this utility model provides a constant temperature chamber for spraying machine material supply, which aims to improve the problems of low accuracy in airflow regulation of the ventilation mechanism, difficulty in accurately maintaining stable environmental conditions, and complex and time-consuming disassembly and maintenance of the air filter in the existing constant temperature chamber for spraying machine material supply.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a constant temperature chamber for feeding a spraying machine, comprising: a constant temperature chamber and a ventilation mechanism, wherein the ventilation mechanism is installed on the top of the constant temperature chamber;

[0009] The ventilation mechanism includes a support ring, an electric push rod, a linkage rod, an adjusting ring, a fixed column, a linkage rod, a fixed rod, blades, and a central shaft. The support ring is fixed to the top of the constant temperature chamber. The electric push rod is fixedly connected to the support ring. The adjusting ring is horizontally slidably fitted to the support ring and is connected to the push rod end of the electric push rod through the linkage rod. The fixed column is connected to the adjusting ring. The linkage rod is connected to the fixed column. The fixed rod is fixedly connected to the linkage ring. The blades are fixedly connected to the fixed rod and are evenly distributed circumferentially around the central shaft.

[0010] Preferably, the constant temperature chamber for the spraying machine's material supply also includes a filter screen and a quick-release mechanism, wherein the filter screen is detachably connected to the air inlet of the ventilation mechanism via the quick-release mechanism.

[0011] More preferably, the quick-release mechanism includes a protective sleeve, a button, a sliding column, a spring, a conical block, and a retaining ball. The sliding column is slidably connected to the inside of the protective sleeve, the button is connected to one end of the sliding column, the conical block is fixedly connected to the other end of the sliding column, the spring is sleeved on the sliding column, and the retaining ball is received in the side wall of the protective sleeve and contacts the conical surface of the conical block.

[0012] Preferably, the linkage ring has an elongated through hole, and the fixing post passes through the elongated through hole.

[0013] Preferably, the blade rotates about the axis of the fixed rod to which it is connected.

[0014] Preferably, the linkage rod is hinged between the push rod end of the electric push rod and the adjusting ring.

[0015] Preferably, the two ends of the spring abut against the inner wall of the protective sleeve and the flange on the sliding post, respectively.

[0016] Preferably, the adjusting ring is coaxially disposed inside the support ring.

[0017] This utility model has the following beneficial effects:

[0018] 1.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-5 This utility model provides a constant temperature chamber for feeding a spraying machine, which aims to solve the problems in the prior art where the ventilation mechanism has low precision in regulating airflow, making it difficult to accurately maintain stable environmental conditions, and the air filter has a complicated disassembly and maintenance process.

[0029] Specifically, it includes a constant temperature chamber 1 and a ventilation system 2 installed on the top of the constant temperature chamber 1. The constant temperature chamber 1 is used to provide a closed and clean basic environmental space for the spray coating feeding process, while the ventilation system 2 is used to deliver clean air with a controllable flow rate into the constant temperature chamber 1 to maintain the environmental conditions required for material feeding.

[0030] The ventilation mechanism 2 includes a support ring 201, an electric push rod 202, a linkage rod 203, an adjusting ring 204, a fixed column 205, a linkage ring 206, a fixed rod 207, blades 208, and a central shaft 209.

[0031] The support ring 201 serves as the mounting base for the ventilation mechanism 2, fixed to the top of the constant temperature chamber 1, providing stable support for the entire ventilation mechanism 2. The electric push rod 202 serves as the power source, its body fixedly connected to the support ring 201. The adjusting ring 204 is a horizontally movable annular component, sliding horizontally on the support ring 201. The adjusting ring 204 is connected to the push rod end of the electric push rod 202 via the linkage rod 203, thus receiving the drive of the electric push rod 202. The fixed column 205 is vertically connected to the adjusting ring 204, moving horizontally synchronously with the adjusting ring 204. The linkage ring 206 is a rotatable annular component, linked to the adjusting ring 204 via the fixed column 205. One end of the fixed rod 207 is fixedly connected to the bottom of the linkage ring 206. Blades 208 are fixedly connected to the fixed rod 207, and all blades 208 are evenly distributed circumferentially around the central axis 209. This entire transmission structure precisely converts the linear motion of the electric push rod 202 into the synchronous rotation of all blades 208, thereby achieving smooth and precise control of the ventilation volume.

[0032] It also includes a filter screen 3 and a quick-release mechanism 4. The filter screen 3 is detachably connected to the air inlet of the ventilation mechanism 2 via the quick-release mechanism 4. This structure allows the replacement or cleaning of the filter screen 3 to be completed quickly without complicated tools, improving the maintenance efficiency and continuous working capability of the equipment.

[0033] The quick-release mechanism 4 includes a protective sleeve 401, a button 402, a sliding post 403, a spring 404, a conical block 405, and a retaining ball 406. The protective sleeve 401 is hollow, providing space and guidance for the internal components. The sliding post 403 is a rod-shaped structure, slidably connected inside the protective sleeve 401, and can reciprocate axially within the protective sleeve 401. The button 402 is fixedly connected to one end of the sliding post 403 extending out of the protective sleeve 401 for easy pressing by the operator. The conical block 405 is fixedly connected to the other end of the sliding post 403 located inside the protective sleeve 401, and has a tapered working surface with a gradually decreasing diameter. The spring 404, as a reset element, is sleeved on the sliding post 403. The retaining ball 406 is a locking element, housed in a through hole in the side wall of the protective sleeve 401, and the inner side of the retaining ball 406 contacts the conical surface of the conical block 405. When the conical block 405 moves, the conical surface of the conical block 405 forces the locking ball 406 to extend or retract radially, thereby locking or releasing.

[0034] Spring 404 is a compression spring. The two ends of spring 404 abut against the inner wall of protective sleeve 401 and the flange specially provided on sliding column 403. When button 402 is pressed, sliding column 403 drives flange to move, thereby compressing spring 404. The stored rebound energy can push sliding column 403 and button 402 to automatically reset after button 402 is released.

[0035] The linkage ring 206 has an elongated through hole, through which the fixing post 205 passes. When the adjusting ring 204 drives the fixing post 205 to move horizontally, the post body of the fixing post 205 slides relative to each other in the elongated through hole. At the same time, the post wall of the fixing post 205 pushes the side wall of the elongated through hole. Since the elongated through hole has a certain inclination angle or curvature, this pushing force is converted into a torque that drives the linkage ring 206 to rotate around its own center, thereby efficiently converting the linear motion of the fixing post 205 into the rotational motion of the linkage ring 206.

[0036] The blade 208 rotates around the axis of the fixed rod 207 to which it is connected. The fixed rod 207 itself acts as a pivot. When the linkage ring 206 rotates, the fixed rod 207 rotates accordingly, thereby driving the blade 208 fixedly connected to the fixed rod 207 to rotate synchronously, changing the windward angle of the blade, and thus adjusting the size of the ventilation cross-sectional area.

[0037] The linkage 203 is hinged to the push rod end of the electric push rod 202 and to the adjusting ring 204. This pin connection allows relative rotation between the connection points, ensuring that when the electric push rod 202 extends or retracts, its linear motion can be smoothly transmitted to the adjusting ring 204, allowing the adjusting ring 204 to slide smoothly horizontally and avoiding motion interference or jamming that may be caused by rigid connection.

[0038] The adjusting ring 204 is coaxially arranged inside the support ring 201. This coaxial arrangement of the inner and outer rings ensures that the adjusting ring 204 always maintains its relative center position with the support ring 201 during the sliding process, providing structural protection for the stable and smooth operation of the entire linkage mechanism and avoiding transmission errors or increased wear that may be caused by eccentric movement.

[0039] Working principle: When the equipment is running, the ventilation mechanism 2 draws in outside air from the top of the constant temperature chamber 1. The air first passes through the built-in filter screen 3, which filters out dust and impurities, ensuring that the air entering the constant temperature chamber 1 is clean and avoiding contamination of the spraying material. If the filter screen 3 needs to be cleaned, it can be quickly disassembled and reassembled through the quick-release mechanism 4, which greatly improves maintenance efficiency and ensures long-term stable operation of the equipment.

[0040] When the equipment is running, the electric push rod 202 is activated, which pushes the linkage rod 203 to drive the adjusting ring 204 to move horizontally. The movement of the adjusting ring 204 drives the fixed column 205 to move synchronously. A linkage ring 206 is provided on the outer wall of the fixed column 205. When the fixed column 205 moves, the linkage ring 206 deflects. Since the bottom of the linkage ring 206 is fixedly connected to the fixed rod 207, the blade 208 and the fixed rod 207 rotate synchronously. The fixed rod 207 then drives the blade 208 to rotate around the central axis 209. At this time, the ventilation mechanism 2 adjusts the air flow into the constant temperature chamber 1 by opening and closing the blade 208. At the same time, the support ring 201 ensures the structural stability of the ventilation mechanism 2, providing clean and controllable air to the constant temperature chamber 1 and maintaining the environmental conditions required for material supply.

[0041] A filter screen 3 is installed on the top of the constant temperature chamber 1. When cleaning the filter screen 3 regularly, a quick-release mechanism 4 is required. By pressing the button 402, the spring 404 is compressed, which at the same time drives the sliding column 403 and the conical block 405 to move downward. As the conical block 405 moves downward, its conical surface no longer squeezes the retaining ball 406. The retaining ball 406 retracts into the protective sleeve 401, releasing the clamping state with the external structure. At this time, the quick-release mechanism 4 can be quickly removed from the constant temperature chamber 1. By releasing the button 402, the return of the spring 404 can drive the button 402 to reset.
