Abstract

This utility model belongs to the field of metal processing technology, specifically relating to a surface drying and curing device for steel template production. It includes a conveyor belt running through the interior of a dryer, with chain plates positioned between the double chains of the conveyor belt. The chain plates gradually arch upwards from both ends towards the center along their length, forming an arched section. A concave arc-shaped groove is formed in the center of this arched section, and the bottom of the groove is coplanar with the top surface of the chain plate. This utility model uses two contact platforms on the arched section to lift the steel template above the chain plates. The arc-shaped groove expands the channel area of ​​the arched section, facilitating smooth flow and exchange of hot air at the bottom of the steel template, improving drying efficiency. Furthermore, the arc-shaped groove and the distance between the chain plates and the steel template increase the observable area of ​​the bottom surface of the steel template, reducing the occurrence of missed inspections.

Description

Technical Field

[0001] This utility model belongs to the field of metal processing technology, and specifically relates to a surface drying and curing device for steel template production. Background Technology

[0002] The surface drying and curing device for steel formwork production is a special equipment used on the steel formwork production line to heat-treat surface coatings (such as anti-rust paint, release agent, functional coating) or adhesive layers. By controlling the temperature and time, it promotes the physical drying or chemical cross-linking reaction of the coating to form a stable protective layer. The main structure includes a plate chain conveyor system (load-bearing), a sealed insulation chamber (environmental isolation), hot air circulation (segmented curing), and intelligent temperature control (process stability). The four structures work together to achieve efficient and uniform coating treatment.

[0003] In existing technologies, the plate chain conveyor belt of steel formwork drying and curing devices is generally set as a slightly downward-sloping V-shape in the middle, so that the steel plate only contacts the two ends of the plate chain through two narrow segments to reduce the friction range. However, the distance between the gradually sloping bottom of this V-shaped structure and the steel formwork is too small. The shallow and narrow channel cannot form an effective negative pressure suction and is easily blocked by the plate, causing airflow short-circuiting. This results in low drying efficiency and unbalanced temperature distribution. In addition, the primer in the area where the V-shaped plate chain overlaps with the steel formwork cannot be directly observed. The primer can only be seen through the narrow gaps between the chain links, resulting in insufficient observation coverage and easy omissions. Utility Model Content

[0004] The purpose of this invention is to provide a surface drying and curing device for steel formwork production. The device lifts the steel formwork above the chain plate by two contact platforms on the arched part, and expands the channel area of ​​the arched part by the arc-shaped groove. This not only facilitates the smooth flow and exchange of hot air at the bottom of the steel formwork, improving drying efficiency, but also increases the observable area of ​​the bottom surface of the steel formwork by the arc-shaped groove and the distance between the chain plate and the steel formwork, reducing the occurrence of missed inspections.

[0005] The specific technical solution adopted by this utility model is as follows: A surface drying and curing device for steel formwork production includes a conveyor belt that runs through the interior of a dryer. A chain plate is provided between the two chains of the conveyor belt. The chain plate gradually arches from both ends to the middle along the length direction to form an arched part. A concave arc-shaped groove is provided in the middle of the arched part, and the bottom of the arc-shaped groove is coplanar with the top surface of the chain plate.

[0006] The arch height of the curved section is not less than twice the thickness of the chain plate.

[0007] An inclined surface is provided on the outer side of the top of the arched part, and a contact platform is formed at the top of the arched part through the inclined surface.

[0008] The bottom of the arc-shaped groove has a through groove along the vertical direction.

[0009] The chain plate is detachably connected to the chain of the conveyor belt via connecting plates at both ends.

[0010] The lower end face of the connecting plate is lower than the bottom face of the chain plate.

[0011] The technical effects achieved by this utility model are as follows: the steel template is lifted above the chain plate by the two contact platforms on the arched part, and the channel area of ​​the arched part is expanded by the arc-shaped groove. This not only facilitates the smooth flow and exchange of hot air at the bottom of the steel template, improving drying efficiency, but also increases the observable area of ​​the bottom surface of the steel template by the arc-shaped groove and the distance between the chain plate and the steel template, reducing the occurrence of missed inspections.

[0014] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0015] like Figures 1-4As shown, a surface drying and curing device for steel formwork production includes a conveyor belt 101 that runs through the interior of a dryer 1. A chain plate 2 is provided between the two chains of the conveyor belt 101. The chain plate 2 gradually arches from both ends to the middle along its length to form an arched section 201. A concave arc-shaped groove 202 is provided in the middle of the arched section 201, and the bottom of the groove 202 is coplanar with the top surface of the chain plate 2. The arch height of the arched section 201 is not less than twice the thickness of the chain plate 2. An inclined surface 203 is provided on the outer side of the top of the arched section 201, and a contact platform 204 is formed at the top of the arched section 201 through the inclined surface 203. A through groove 205 is provided on the bottom of the arc-shaped groove 202 in the vertical direction. The chain plate 2 is detachably connected to the chain of the conveyor belt 101 through connecting plates 206 at both ends. The lower end surface of the connecting plate 206 is lower than the bottom surface of the chain plate 2.

[0016] According to the above structure, the connecting plate 206 is fixedly connected to the pin of the conveyor belt 101 chain by fastening bolts. When the conveyor belt 101 starts, it will drive the chain plate 2 to move, conveying the steel template on the top of the chain plate 2 into the dryer 1. Due to the upward arch of the arched part 201, the steel template cannot contact the chain plate 2, and a gap is formed between the steel plate and the chain plate 2. Both arched parts 201 form point contact to support the steel plate through the contact platform 204. The middle of the steel plate can be observed through the arc-shaped groove 202. The inclined surfaces 203 not only reduce the contact area between the arched part 201 and the steel plate, but also prevent the tip of the arched part 201 from contacting and colliding with the steel plate when the arched part 201 rotates around the end pulley of the conveyor belt 101. The arc shape of the arc groove 202 greatly expands the airflow channel compared to the slowly inclined line in the traditional design. The through groove 205 further expands the airflow channel, reduces the weight of the chain plate 2, and allows particulate impurities generated during processing to fall directly.

[0017] The working principle of this utility model is as follows: the connecting plate 206 is stably connected to the pin of the conveyor belt 101 chain via fastening bolts; the above connection method is the preferred embodiment. In actual application, the connecting plate 206 can also be connected to other compatible parts of the conveyor belt 101 according to the overall structural requirements of the equipment. The specific connection form should be determined according to the actual working conditions. Furthermore, when the conveyor belt 101 is running, its driving force is transmitted to the chain plate 2, causing the steel template carried on the top of the chain plate 2 to enter the dryer 1 in an orderly manner. Thanks to the arched design of the arched part 201, the steel template and the chain plate 2 remain in a non-contact state, forming a specific gap between them. Under this structure, the two arched parts 201 support the steel template in a point contact manner with the contact platform 204 at their respective tops, which not only ensures the stability of the conveying but also minimizes the contact area. The existence of the arc-shaped groove 202 allows the operator to intuitively observe the middle and side areas of the steel template. Furthermore, the inclined surface 203 effectively reduces the contact range between the arched part 201 and the steel template. On the other hand, when the arched part 201 moves in a circular motion with the end wheel of the conveyor belt 101, it can accurately avoid the risk of the tip colliding with the steel template. Compared with the traditional gently inclined linear structure, the arc groove 202 significantly widens the airflow channel. With the addition of the through groove 205, it not only further expands the airflow space, but also realizes the lightweight design of the chain plate 2. At the same time, it facilitates the direct discharge of particulate impurities generated during the processing.

[0018] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
