Description

Technical Field

[0001] This utility model relates to the field of fastener production equipment technology, specifically to a drying device for microcapsule pre-coated fasteners. Background Technology

[0002] Chemical adhesives used on fasteners and screws are commonly referred to as fastening adhesives or anaerobic sealants. These adhesives are primarily used to ensure that screws do not come loose during operation. Existing technology involves pre-applying anaerobic sealant encapsulated in small capsules onto the fasteners. When the fasteners are tightened, the threaded engagement breaks the capsules, allowing the sealant to penetrate deep into the threads and prevent loosening.

[0003] The problem with existing technologies is that microcapsule chemical adhesives applied to the threaded surface of fasteners need to be dried and cured. However, the traditional method is to send fasteners covered with chemical adhesives into an oven in batches for drying. Drying is a gradual process. If the amount of hot air in the oven can be adjusted according to the drying process, such as increasing or decreasing the amount of hot air for a certain part of the stroke, the drying efficiency can be significantly improved by changing the amount of hot air for certain areas of thick coating or thin coating on the fasteners.

[0004] Furthermore, to ensure the drying effect, the fasteners need to remain in the oven for a certain period of time. To avoid stagnation and reduced production efficiency, the oven is designed to be relatively long, so that the time it takes for the fasteners to pass through the oven precisely meets the process requirements. However, this often results in the oven taking up a lot of space and causing heat loss, leading to additional costs.

[0005] Therefore, to address the aforementioned issues, it is necessary to improve the design of existing drying equipment. Utility Model Content

[0006] To address the shortcomings of the aforementioned technologies, this invention provides a drying device for microcapsule pre-coated fasteners.

[0007] The technical solution of this utility model: A drying device for microcapsule pre-coated fasteners, including a housing, a conveyor belt, a transmission mechanism and a hot air blower. The housing includes a drying chamber for the conveyor belt to pass through. The drying chamber is provided with an air inlet plate, an adjusting plate and several opening and closing doors on both sides of the conveyor belt. The air inlet plate is provided with several ventilation holes and connecting columns. The adjusting plate is provided with misaligned holes corresponding to each ventilation hole and elongated grooves that slide with the connecting columns. The adjusting plate slides relative to the connecting columns to control the size of the connecting portion between the misaligned holes and the ventilation holes.

[0008] The hot air blower is equipped with an air duct that extends through the casing to the space between the regulating plate and the opening / closing door. The air duct delivers hot air into the drying chamber through the misalignment hole and the ventilation hole. The opening / closing door can open or close the casing.

[0009] A further feature of this invention is that the conveyor belt is equipped with a transmission chain and several fastener clamps. The conveyor belt includes an inlet / outlet end extending outside the machine housing and a rotating end arranged in several overlapping layers inside the drying chamber. The transmission mechanism includes several guide sprockets and a drive motor. The guide sprockets mesh with the transmission chain of the conveyor belt and guide the conveyor belt to change direction. The drive motor is linked with the guide sprocket to drive the conveyor belt to carry the fasteners and rotate in and out of the drying chamber.

[0010] A further feature of this invention is that the air inlet plate has several layers of ventilation holes at its rotating end corresponding to several overlapping layers, and several adjusting plates are provided corresponding to the number of layers. These adjusting plates can independently adjust the position of the misaligned holes.

[0011] A further feature of this invention is that the fastener clamp includes a magnetic base with a groove that matches the contour of the fastener.

[0012] The beneficial effects of this utility model are as follows: First, through the design of the casing structure of the drying equipment, the conveyor belt carrying the fasteners to be dried passes through the drying chamber. An air inlet plate, an adjusting plate, and an opening and closing door are mirrored on both sides of the drying chamber. The air inlet plate separates the casing, and an air inlet chamber is formed between the air inlet plate and the opening and closing door. The hot air produced by the hot air blower is uniformly input into the air inlet chamber through the air duct, and then seeps into the drying chamber through various ventilation holes and misaligned holes. According to the position of the ventilation hole, the air is blown to the preset designated position. The opening and closing of the opening and closing door can be manually operated to control the adjusting plate, that is, to control the size and opening and closing of the overlapping part of the misaligned hole and the ventilation hole, so as to control the amount of hot air entering the drying chamber and the heat sealing blowing position.

[0013] As per the instruction manual Figure 3 The conveyor belt layout shown extends to the inlet and outlet ends outside the machine casing for fastener loading and unloading on the same side. This saves space and equipment compared to a single inlet and outlet, and facilitates the use of an automated loading and unloading device. The rotating ends arranged in several overlapping layers within the drying chamber maximize the use of the vertical space of the machine casing for fastener drying, reducing the equipment footprint. At the same time, the multi-layer adjustment plate design allows fasteners at each layer to receive independently customized hot air volume and position for drying.

[0014] The magnetic base's clamping design allows for quick attachment of fasteners, and they are less likely to fall off as the wheel rotates. It works in conjunction with mechanical grippers to handle loading and unloading operations. Attached Figure Description

It should be understood that the specific embodiments described herein are only some embodiments of this application, and are only used to explain this application, not to limit this application. It should be noted that, for ease of description, only the parts related to this application are shown in the accompanying drawings. Other related parts can be referred to the general design. In the absence of conflict, the embodiments and technical features in the embodiments of this application can be combined with each other to obtain new embodiments.

[0023] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figures 1-5 As shown,

[0024] A drying device for microcapsule pre-coated fasteners includes a housing 1, a conveyor belt 2, a transmission mechanism, and a hot air blower 3. The housing 1 includes a drying chamber 11 through which the conveyor belt 2 passes. The drying chamber 11 is provided with an air inlet plate 4, an adjusting plate 5, and several opening and closing doors 6 on both sides of the conveyor belt 2. The air inlet plate 4 is provided with several ventilation holes 41 and connecting posts 42. The adjusting plate 5 is provided with misaligned holes 51 corresponding to each ventilation hole 41 and elongated grooves 52 that slide with the connecting posts 42. The adjusting plate 5 slides with the connecting posts 42 to control the size of the connecting portion between the misaligned holes 51 and the ventilation holes 41.

[0025] The hot air blower 3 is provided with an air duct 31 that passes through the housing 1 and extends to the space between the regulating plate 5 and the opening and closing door 6. The air duct 31 delivers hot air into the drying chamber 11 through the misalignment hole 51 and the ventilation hole 41. The opening and closing door 6 opens or closes the housing 1.

[0026] The conveyor belt 2 is equipped with a transmission chain 21 and several fastener clamps 22. The conveyor belt 2 includes an inlet / outlet end 23 extending outside the housing 1 and a rotating end 24 arranged in several overlapping layers inside the drying chamber 11. The transmission mechanism includes several guide sprockets 25 and a drive motor. The guide sprockets 25 mesh with the transmission chain 21 of the conveyor belt 2 and guide the conveyor belt 2 to turn. The drive motor is linked with the guide sprocket to drive the conveyor belt 2 to carry the fasteners and rotate in and out of the drying chamber 11.

[0027] The air inlet plate 4 is provided with several layers of ventilation holes 41 at the rotating end 24 corresponding to several overlapping layers, and several adjustment plates 5 are provided corresponding to the number of layers. The positions of the misalignment holes 51 are adjusted independently by the several adjustment plates 5.

[0028] The fastener clamp 22 includes a magnetic base with a groove that matches the profile of the fastener.

[0029] This application, through the structural design of the casing 1 of the drying equipment, allows the conveyor belt 2 carrying the fasteners to be dried to pass through the drying chamber 11. An air inlet plate 4, an adjusting plate 5, and an opening / closing door 6 are mirror-mounted on both sides of the drying chamber 11. The air inlet plate 4 separates the casing 1, forming an air inlet chamber between the air inlet plate 4 and the opening / closing door 6. Hot air produced by the hot air blower 3 is uniformly input into the air inlet chamber through the air duct 31, and then seeps into the drying chamber 11 through various ventilation holes 41 and misaligned holes 51. The air is blown onto preset designated locations according to the position of the ventilation holes 41. The opening and closing of the opening / closing door 6 allows for manual operation to control the adjusting plate 5, i.e., controlling the size and opening / closing of the overlapping portion of the misaligned hole 51 and the ventilation hole 41, thereby controlling the amount of hot air entering the drying chamber 11 and the heat-sealing blowing position.

[0030] As per the instruction manual Figure 3 The conveyor belt 2 shown is arranged so that it extends to the inlet and outlet end 23 outside the housing 1 to load and unload fasteners on the same side. This saves space and equipment compared to the one-in-one-out-of-the-side method, and facilitates the use of an automated loading and unloading device. The rotating end 24, which is arranged in several overlapping layers in the drying chamber 11, maximizes the use of the vertical space of the housing 1 for the fastener drying stroke, reducing the space occupied by the equipment. At the same time, with the design of the multi-layer adjustment plate 5, the fasteners at each layer can be dried with independent and customized hot air volume and position.

[0031] The magnetic base's clamping design allows for quick attachment of fasteners, and they are less likely to fall off as the wheel rotates. It works in conjunction with mechanical grippers to handle loading and unloading operations.

[0032] The technical solution of this application has been described in conjunction with the preferred embodiments shown in the accompanying drawings. Those skilled in the art should understand that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
