Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of prototype models, and in particular to a drying device for easy spraying of prototype models. Background Technology
[0002] In the product development process, prototype models are a crucial step in verifying product feasibility. Once the prototype models are completed, they usually need to be painted to improve their aesthetics, cover surface defects, and enhance durability. Painting can give the prototypes a variety of colors and unique textures and improve their electrostatic properties. However, the painted prototypes need to be dried quickly and evenly to ensure paint quality and production efficiency. Traditional natural drying methods are inefficient and cannot meet the requirements, so drying equipment has emerged.
[0003] However, existing drying equipment is not convenient for confining the painted prototype model on the support platform during use. As a result, the prototype model may fall off the support platform when it is moved, causing damage to the prototype model and resulting in economic losses. Utility Model Content
[0004] The purpose of this utility model is to provide a drying device for easy spraying of prototype models. By setting up an anti-fall part, it solves the problem that existing drying devices are not convenient to restrain the sprayed prototype model on the support platform during use, which causes the prototype model to fall off the support platform when moving, resulting in damage to the prototype model and economic loss.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a drying device for easy painting of hand-made models, including a housing, and further including: a plurality of anti-fall parts, all of which are disposed inside the housing; a movable part, located inside the housing; the anti-fall parts include an opening and closing assembly, which is disposed inside the housing; and three blocking assemblies, all of which are disposed inside the housing; the opening and closing assembly includes a support rod disposed inside the housing, the top of the support rod is fixedly connected to a lifting platform, the inner wall of the lifting platform is fixedly connected to three telescopic rods, all of which penetrate the lifting platform, and the top of the three telescopic rods is fixedly connected to a bracket; wherein, the three telescopic rods are arranged in a circumferential array, and the bracket is a triangular bracket.
[0007] Furthermore, the movable part includes a drying assembly mounted on the top of the chassis, the bottom of the drying assembly extending into the chassis; and a rotating assembly disposed at the bottom of the chassis, the top of the rotating assembly extending into the chassis; wherein the drying assembly is located above the rotating assembly.
[0008] Furthermore, the barrier assembly includes two pivots rotatably connected to the inner wall of the lifting platform. A fence is slidably connected to the inner wall of each pivot. Two connecting ropes are fixedly connected to the outer wall of the fence. The sides of the two connecting ropes that are far apart from each other are fixedly connected to a support. An elastic element is provided at the bottom of the fence. The elastic element is located at the bottom of the lifting platform and includes a limiting rod fixedly connected to the bottom of the lifting platform. The outer wall of the limiting rod is slidably connected to the fence and passes through the fence. A spring is sleeved on the outer wall of the limiting rod. The bottom of the spring is fixedly connected to the fence, and the top of the spring is fixedly connected to the lifting platform. The limiting rod is a rod with a limiting block at the bottom. The automatic opening and closing of the fence is achieved through spring tension, forming a protective structure for the hand model to prevent it from falling, and the operation is simple.
[0009] Furthermore, the drying assembly includes a connecting pipe connected to the top of the chassis. The top of the chassis has a ventilation hole one, and the bottom of the connecting pipe is connected to the ventilation hole one. The inner wall of the ventilation hole one has several ventilation holes two. The ventilation holes two are arranged in a circular array. Hot air is blown out through the circular array of ventilation holes two to achieve all-round drying of the model and avoid drying dead corners.
[0010] Furthermore, the rotating assembly includes a connecting block rotatably connected to the inner wall of the chassis. A motor is fixedly connected to the bottom of the chassis. A second rotating shaft is rotatably connected to the inner wall of the chassis. The top of the second rotating shaft is fixedly connected to the connecting block, and the bottom of the second rotating shaft extends to the outside of the chassis. The output shaft of the motor is fixedly connected to the second rotating shaft via a coupling. The inner walls of several support rods are rotatably connected to the connecting block. A transmission component is provided on the connecting block. The connecting block is a circular block. The transmission component includes an internal gear ring fixedly connected to the inner wall of the chassis. A gear is fixedly connected to the outer wall of the support rod. The support rod passes through the gear, and the gear meshes with the internal gear ring. The internal gear ring is an annular block with teeth on its inner side. Through motor drive and gear transmission, the prototype model rotates on its own axis while revolving around the central axis, which, in conjunction with the drying assembly, improves drying efficiency and uniformity.
[0011] This utility model has the following beneficial effects:
[0012] 1. By setting up anti-fall devices, when the painted prototype model is placed on the support platform, the railings move upward under the action of spring tension. The three railings form a barrier structure to prevent the prototype model from falling off the support platform, providing reliable anti-fall protection. At the same time, the design of the opening and closing components makes the opening and closing operation of the railings simple. It can be achieved by stretching or loosening the brackets, which facilitates the placement and removal of the prototype model. It can place the prototype model on the support platform and restrain it, preventing the prototype model from falling off the support platform due to vibration during movement, avoiding damage to the model and economic losses, thereby reducing production costs, and ensuring the stable drying of the prototype model.
[0013] 2. By incorporating a moving part, when the prototype model needs to be dried, the motor drives the connecting block to rotate, causing the support rod to revolve around the second rotating shaft. Simultaneously, under the meshing action of the internal gear ring and the gear, the support rod rotates on its own axis. This allows the prototype model to revolve around the machine while simultaneously rotating on its own axis. This composite motion, combined with the drying components, allows hot air to enter through the connecting pipe and then be blown out through the circumferentially distributed ventilation holes. This movement of the prototype model ensures even heating of all parts, preventing localized cracking or incomplete drying, thereby reducing the scrap rate of the prototype model and further reducing production costs.
[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] A specific application of this embodiment is as follows: In use, the bracket 214 can be pulled, causing it to stretch the telescopic rod 213, thereby causing the connecting rope 223 to move upward.

When the fence 222 moves downward, it will slide on the outer wall of the limiting rod 224, thereby stretching the spring 225 and generating tension. When the telescopic rod 213 is fully stretched, the painted hand model can be placed on the lifting platform 212, and then the bracket 214 can be released. At this time, under the action of the tension of the spring 225, the fence 222 will move upward, thereby transmitting the force to the connecting rope 223, causing it to move upward. When the model is in motion, the tension of the connecting rope 223 is converted into a downward tension on the bracket 214 under the action of the rotating shaft 221, thereby resetting the bracket 214. When the prototype model needs to be dried, the motor 322 can be started, and its output shaft drives the rotating shaft 323 to rotate, thereby driving the connecting block 321 to rotate. When the connecting block 321 rotates, it will drive the support rod 211 to rotate around the rotating shaft 323. At this time, under the action of the internal gear ring 324, the support rod 211 will rotate through the gear 325, so that the prototype model will revolve within the machine box 101 while rotating on its own axis. Then, hot air can be blown from the connecting pipe 311 into the ventilation hole 312, and then the hot air will dry the prototype model through the ventilation hole 313.
