Description

Technical Field

[0001] This utility model relates to the field of umbrella surface processing, specifically a drying rack for umbrella surface production. Background Technology

[0002] The canopy is the shielding part of an umbrella, usually made of fabric, plastic, or other flexible materials, and covers the ribs. Its main function is to unfold into a certain arc when opened to block sunlight, rain, or snow. The shape, color, and pattern of the canopy vary, making it the most visually appealing part of the umbrella, and it often serves as a decorative element and a way to express individuality.

[0003] Chinese patent discloses a drying device for textile fabric processing (authorization announcement number CN216592639U). The patented technology includes a shell, an exhaust assembly, a steam pipe, and a heat circulation pipe. The exhaust assembly is installed at the top center of the shell. A three-way connector is installed on the top of the exhaust assembly. A heat circulation pipe is installed on one side of the top of the three-way connector. A steam pipe is installed on the side of the three-way connector away from the heat circulation pipe. A mounting bracket is installed on the bottom outer side of the steam pipe. Electric telescopic rods are installed on both sides of the mounting bracket. An ironing device is installed at the bottom of the electric telescopic rods.

[0004] However, existing technologies have the following problems when used:

[0005] Firstly, the heating source is often fixed, and the umbrella surface is stationary while being dried. This can easily lead to localized heat concentration and insufficient heating at the edges, resulting in uneven curing of the coating. Some areas may meet the waterproofing and other performance standards, while others may be unusable due to poor curing.

[0006] Secondly, relying on mechanical structures to clamp and fix the umbrella surface makes it difficult to control the clamping force, which can easily damage the coating. Furthermore, the clamping components may obstruct certain areas of the umbrella surface, resulting in incomplete drying of those areas and affecting the overall quality. Utility Model Content

[0007] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a drying rack for umbrella surface production, so as to solve the technical problems of uneven heating leading to poor coating curing effect, and mechanical clamping easily damaging the coating and blocking the heating area in the current traditional umbrella surface coating drying process.

[0008] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a drying rack for umbrella surface generation is designed, including a cylinder and bolts. A cylinder groove is installed at the upper end of the cylinder, and an installation plate is detachably installed on the inner wall of the cylinder groove. A heating strip is installed at the lower end of the installation plate. A first rotating rod is rotatably connected to the inner wall of the cylinder groove. A placement plate is installed at the upper end of the first rotating rod. An umbrella surface body is placed on the upper end of the placement plate. A first gear is installed at the lower end of the first rotating rod, and a second rotating rod is rotatably installed at the lower end of the first gear.

[0009] A disc is rotatably connected to the first rotating rod. A first pipe is installed at the lower end of the disc. A hose is connected to the lower end of the first pipe, and a housing is connected to the end of the hose. A rotating blade is rotatably connected inside the housing. A third rotating rod is installed at the upper end of the rotating blade. A second gear is installed at the upper end of the third rotating rod, and the second gear meshes with the first gear. A third pipe is installed at the front end of the housing.

[0010] In this design, the cylindrical groove provides installation space for the components, and the removable mounting plate facilitates maintenance and position adjustment of the heating strips. A motor drives a second rotating rod, and a first gear drives the first rotating rod and placement tray to rotate at low speed, causing the umbrella surface to rotate with the tray, allowing the heating strips to evenly heat all areas of the umbrella surface. Simultaneously, the first gear meshes with the second gear, which in turn drives the rotating blades inside the shell groove via the third rotating rod, generating negative pressure. This negative pressure, transmitted through a hose and a first pipe, creates a vacuum in the annular groove of the tray, adsorbing and fixing the umbrella surface, preventing mechanical clamping from damaging the coating. The uncovered air vents on the placement tray allow outside air to balance the negative pressure, ensuring the umbrella surface remains intact and improving drying quality and yield.

[0011] Preferably, three pillars are installed in a circular array at the lower end of the cylinder, and a support plate is installed at the lower end of each of the three pillars.

[0012] In practical applications, three pillars arranged in a ring at the lower end of the cylinder are installed, with support plates at their lower ends to provide stable support for the equipment. The triangular support structure evenly distributes the equipment's weight, enhances its anti-tipping ability, prevents equipment swaying caused by motor vibration, and ensures the stability of the canopy on the placement plate. The support plate increases the contact area with the ground, reducing the pressure exerted by the equipment on the ground, adapting to various ground environments, and increasing friction to prevent equipment slippage. Simultaneously, the pillars create a gap between the lower end of the cylinder and the ground, facilitating the installation, maintenance, and heat dissipation of components such as the motor and the first support, thus extending the equipment's lifespan.

[0013] Preferably, a mounting bracket is installed on the inner wall of the cylindrical groove, a mounting plate is inserted into the mounting bracket, and the mounting bracket and the mounting plate are connected by bolts.

[0014] In practical applications, the mounting bracket provides stable support for the mounting plate, ensuring the heating strip is fixed in position. The mounting plate can be quickly positioned by inserting it into the bracket, and the bolted connection enhances stability, resisting equipment vibration and preventing it from falling off. The removable nature of the bolted connection allows for easy removal and maintenance of the heating strip without disassembling the main equipment body in case of heating strip failure, reducing maintenance costs. It also facilitates regular removal of the mounting plate for cleaning the heating strip and drum, ensuring heating efficiency and drying quality.

[0015] Preferably, a first bracket is installed at the lower end of the cylinder, a motor is installed at the lower end of the first bracket, and the lower end of the first rotating rod is connected to the motor drive end.

[0016] In practical applications, a first support is installed at the lower end of the cylinder, and the motor is mounted at the lower end of the support. A first rotating rod is connected to the motor drive end to provide stable power. The first support fixes the motor, preventing motor shaking during operation and ensuring stable power transmission. The direct connection between the motor and the first rotating rod reduces intermediate links in power transmission, improves transmission efficiency, and reduces wear on transmission components. Stable motor operation ensures uniform rotation speed of the first rotating rod, causing the placement tray and umbrella surface to rotate at a uniform speed, ensuring consistent heating time for the heating strips on the umbrella surface, and improving drying uniformity.

[0017] Preferably, the upper end of the placement plate has an air guide hole, the upper end of the disc has an annular groove, the upper end of the disc fits against the lower end of the placement plate, the upper end of the disc has a through hole, a bearing is installed in the through hole, and the lower end of the first rotating rod passes through the bearing.

[0018] In practical applications, the air vents in the placement tray allow air to be directed from below the umbrella surface to enhance adsorption. Simultaneously, when the negative pressure is too high, external air is introduced to balance the pressure and prevent damage to the umbrella surface. The disc fits tightly against the lower end of the placement tray to prevent air leakage and ensure stable negative pressure. A bearing inside the disc's through-hole allows the first rotating rod to drive the placement tray to rotate freely, while simultaneously fixing the disc and reducing frictional loss between the rotating rod and the disc. This achieves coordinated operation of rotational drying and negative pressure adsorption, balancing drying uniformity and umbrella surface stability.

[0019] Preferably, the shell has a groove inside, a second pipe is installed at the front end of the shell and the second pipe is connected to the groove, and the third pipe is connected to the groove.

[0020] In practical applications, the casing provides working space for the rotating blades, ensuring a stable negative pressure generated during blade rotation. The second and third pipes form airflow inlets and outlets. When the blades rotate, air enters the casing through the second pipe and exits through the third pipe, achieving airflow circulation. This circulation maintains stable negative pressure, prevents airflow congestion, and removes heat generated during equipment operation, aiding in heat dissipation. The pipes facilitate connection to external filters or guide devices to filter air, improving drying quality, or guide airflow direction to avoid impacting the workshop environment, enhancing the equipment's usability.

[0021] Preferably, a second bracket is installed at the lower end of the cylinder, the rear end of the shell is connected to the second bracket, and the rotating blade is rotatably connected to the shell groove.

[0022] In practical applications, the second bracket transmits the weight of the housing and the rotational force of the impeller to the cylinder, preventing the housing from swaying or shifting, ensuring a tight connection between the housing and the hose and the first pipe to prevent air leakage, and guaranteeing negative pressure efficiency. The fixed housing keeps the impeller at the correct rotation center, avoiding friction with the inner wall of the housing groove, reducing wear and noise. The flexible rotation of the impeller efficiently generates negative pressure, and the second bracket facilitates adjustment of the housing position, ensuring gear engagement, and also allows for easy disassembly of the housing for maintenance of internal components, reducing maintenance difficulty.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] 1. When drying the umbrella surface coating using this utility model, the operator first lays the umbrella surface to be dried flat on the placement tray to avoid uneven heating caused by folding. Then, the mounting plate with heating strips is inserted into the mounting bracket on the inner wall of the cylinder groove, and the two are firmly connected with bolts. This prevents the heating strips from shifting due to vibration during equipment operation and facilitates subsequent maintenance. After starting the motor, its driving force is transmitted to the second rotating rod and the first gear in sequence, causing the first rotating rod and the placement tray to rotate at a low speed. The umbrella surface rotates synchronously with it. At this time, the heating strips continuously release heat. Because the umbrella surface rotates at a uniform speed, the heat can evenly cover all areas of the umbrella surface, effectively avoiding the problems of local overheating and aging or insufficient heating in traditional fixed drying, ensuring uniform curing of the coating and improving processing quality.

[0025] 2. When the motor drives the first gear to rotate, the second gear rotates synchronously. The second gear drives the rotating blade inside the housing to rotate in the housing groove through the third rotating rod, thereby forming a negative pressure in the housing groove. Under the action of negative pressure, the air in the annular groove at the upper end of the disc is drawn into the housing groove through the first pipe and hose, so that the annular groove also generates a stable negative pressure. Since the disc and the lower end of the placement tray are tightly attached, the negative pressure adsorbs the umbrella body onto the placement tray through the air guide hole of the placement tray. The air guide hole not covered by the umbrella will introduce outside air to balance the negative pressure in the annular groove and prevent the umbrella from deforming. The negative pressure limit replaces the traditional mechanical clamping, avoiding coating scratches and damage caused by improper clamping force, and will not affect drying due to the obstruction of clamping parts, thus ensuring the integrity and drying uniformity of the umbrella coating.

[0048] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0049] Example 1: A drying rack for umbrella fabrication, see [link to example]. Figures 1 to 8The device includes a cylinder 110 and bolts 140. A groove 111 is installed on the upper end of the cylinder 110, and a mounting plate 120 is detachably installed on the inner wall of the groove 111. A heating strip 130 is installed on the lower end of the mounting plate 120. A first rotating rod 250 is rotatably connected to the inner wall of the groove 111. A placement plate 230 is installed on the upper end of the first rotating rod 250, and an umbrella surface body 240 is placed on the upper end of the placement plate 230. A first gear 210 is installed on the lower end of the first rotating rod 250, and the lower end of the first gear 210 is rotatably mounted... There is a second rotating rod 260; three pillars 100 are installed in a circular array at the lower end of the cylinder 110, and support plates are installed at the lower ends of the three pillars 100 respectively; a mounting bracket 150 is installed on the inner wall of the cylinder groove 111, a mounting plate 120 is inserted into the mounting bracket 150, and the mounting bracket 150 and the mounting plate 120 are connected by bolts 140; a first bracket 220 is installed at the lower end of the cylinder 110, a motor 200 is installed at the lower end of the first bracket 220, and the lower end of the first rotating rod 250 is connected to the drive end of the motor 200;

[0050] When drying the coating after processing the umbrella surface, the operator must first place the umbrella body 240 to be dried stably on the upper surface of the placement tray 230 to ensure that the umbrella body 240 is kept in a stretched state on the placement tray 230, so as to avoid uneven heating of the coating during the subsequent drying process due to folding or stacking.

[0051] Subsequently, the mounting plate 120 equipped with the heating strip 130 is aligned with the mounting bracket 150 pre-set on the inner wall of the cylinder groove 111 and slowly inserted into the slot of the mounting bracket 150. After the mounting plate 120 is positioned, the mounting plate 120 and the mounting bracket 150 are firmly connected using bolts 140. The bolt connection not only ensures the stability of the mounting plate 120 during equipment operation and prevents the heating strip 130 from shifting due to equipment vibration, but also provides convenience for the subsequent maintenance and replacement of the heating strip 130.

[0052] When the motor 200 of the device is started, the driving force of the motor 200 is sequentially transmitted to the second rotating rod 260 and the first gear 210, which in turn drives the first rotating rod 250 and the placement tray 230 to rotate at a preset speed. The umbrella body 240 on the placement tray 230 will also rotate synchronously. At this time, the heating strip 130 at the lower end of the mounting plate 120 will continuously release heat. Since the umbrella body 240 is in a state of uniform rotation, the heat released by the heating strip 130 can evenly cover every area of ​​the umbrella body 240. Whether it is the center or the edge of the umbrella, it can obtain a sufficient and consistent heating effect, which effectively avoids the problems of excessive local heating of the umbrella surface leading to coating aging, or insufficient local heating leading to incomplete drying of the coating in traditional fixed drying methods. This ensures that the coating of the umbrella body 240 can be uniformly cured, improving the processing quality of the umbrella surface.

[0053] For details, see Figures 1 to 8A disc 340 is rotatably connected to the first rotating rod 250. A first pipe 350 is installed at the lower end of the disc 340. A hose 300 is connected to the lower end of the first pipe 350, and a housing 320 is connected to the end of the hose 300. A rotating blade 380 is rotatably connected inside the housing 320. A third rotating rod 370 is installed at the upper end of the rotating blade 380. A second gear 310 is installed at the upper end of the third rotating rod 370, and the second gear 310 meshes with the first gear 210. A third pipe 391 is installed at the front end of the housing 320. A vent hole 231 is opened at the upper end of the placement plate 230, and a ring is opened at the upper end of the disc 340. The upper end of the disc 340 is fitted with the lower end of the disc 230. The upper end of the disc 340 has a through hole 342, and a bearing 360 is installed in the through hole 342. The lower end of the first rotating rod 250 passes through the bearing 360. The shell 320 has a shell groove 321 inside. The front end of the shell 320 is equipped with a second pipe 390, which is connected to the shell groove 321. A third pipe 391 is also connected to the shell groove 321. The lower end of the cylinder 110 is equipped with a second support 330. The rear end of the shell 320 is connected to the second support 330. The rotating blade 380 is rotatably connected to the shell groove 321.

[0054] During the rotation of the first gear 210 driven by the motor 200, the first gear 210 drives the second gear 310, which is meshed with it, to rotate synchronously. The rotation of the second gear 310 is transmitted to the rotating blade 380 inside the housing 320 through the third rotating rod 370, causing the rotating blade 380 to rotate within the shell groove 321 of the housing 320. The rotation of the rotating blade 380 creates a negative pressure environment within the shell groove 321. Under the suction effect of the negative pressure, the air in the annular groove 341 at the upper end of the disc 340 is sequentially introduced into the shell groove 321 through the first pipe 350 and the hose 300, thus creating a stable negative pressure within the annular groove 341 as well.

[0055] Since the upper end face of the disc 340 is in close contact with the lower end face of the placement plate 230, the negative pressure in the annular groove 341 will be transmitted to the lower part of the umbrella body 240 through the air guide hole 231 on the placement plate 230. Under the action of atmospheric pressure, the umbrella body 240 will be adsorbed on the upper end face of the placement plate 230, thus achieving stable fixation of the umbrella.

[0056] Meanwhile, for the air vents 231 on the placement tray 230 that are not covered by the umbrella body 240, outside air will be naturally introduced into the annular groove 341 through these air vents 231, thereby effectively balancing the negative pressure intensity in the annular groove 341, preventing the umbrella body 240 from being over-adsorbed due to excessive negative pressure, resulting in deformation, wrinkles, and other problems, and ensuring that the umbrella body 240 remains flat during the drying process.

[0057] The method of fixing the umbrella surface by negative pressure replaces the traditional mechanical clamping method. Traditional clamping methods often cause scratches, damage, or even peeling of the coating after the umbrella surface is processed due to improper control of clamping force. At the same time, the clamping parts will also block part of the umbrella surface, affecting the normal drying of the coating in that area. While achieving stable fixing of the umbrella surface, it will not cause any damage to the coating or hinder the drying process. This allows every part of the coating on the umbrella surface 240 to fully contact the heat, further ensuring the uniformity and integrity of the drying process.

[0058] It should be noted that the motor 200 mentioned in the article is existing technology that can be found. The motor 200 is a conventional servo motor. Its working principle revolves around the closed-loop control logic of signal feedback and deviation correction. The core is to continuously compare the command signal with the actual operating state and adjust the motor output in real time to eliminate deviation, thereby achieving precise control.

[0059] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
