Description

Technical Field

[0001] This utility model relates to the field of wood processing equipment technology, and in particular to a wood box anti-corrosion coating device. Background Technology

[0002] Wooden crates are an important type of packaging and transportation container, widely used in logistics, warehousing and export trade. In order to extend the service life of wooden crates and prevent them from rotting and being damaged by moisture, insects and other factors during use and storage, they usually need to be coated with anti-corrosion paint.

[0003] In existing production processes, after the anti-corrosion coating is applied to wooden crates, they need to undergo a necessary drying process to allow the coating to cure and form an effective protective layer. Currently, there are two common drying methods: one is natural air drying, which is simple and easy to implement, but the drying speed is extremely slow, heavily dependent on weather conditions, and occupies a lot of space, making it impossible to meet the needs of large-scale, high-efficiency production; the other is hot air drying or oven baking, which can shorten the drying time, but usually adopts a static drying mode.

[0004] In static drying mode, the wooden crates are fixedly placed in the drying area, and the positions of the heating and blowing devices are also fixed. This results in differences in the heat and airflow intensity received by different parts of the wooden crate surface. Areas closer to the heat source or air vent tend to dry too quickly, which may even cause the coating to blister or the wood to crack. Areas farther away or in airflow dead zones dry slowly, and the coating may remain wet. This uneven drying not only affects the appearance quality of the wooden crate, but more importantly, it weakens the overall protective effect of the anti-corrosion coating and reduces the durability of the wooden crate.

[0005] Therefore, this utility model proposes a wooden box anti-corrosion coating device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of low drying efficiency after coating and uneven drying of the coating on the surface of the wooden box due to static drying in the existing wooden box anti-corrosion coating device, which affects the final anti-corrosion quality, this utility model aims to provide a wooden box anti-corrosion coating device with improved structure that can achieve fast and uniform drying.

[0007] This utility model provides a wooden box anti-corrosion coating device, including a workbench, a mounting base fixed on the workbench, a movable plate slidably disposed above the mounting base, a protective cover, a drying component, and a reciprocating component.

[0008] The protective cover is positioned above the movable plate, and the drying assembly includes a fan installed on the inner wall of the protective cover and a serpentine heating tube sealed inside the mounting base.

[0009] Furthermore, the reciprocating assembly is used to drive the moving plate to reciprocate. The reciprocating assembly includes a motor, a gear fixedly connected to the output end of the motor, a rack meshing with the gear, a fixed bracket fixed to the upper surface of the mounting base, and a connecting slider. The fixed bracket has a sliding groove for the connecting slider to slide. One end of the connecting slider is connected to the rack, and the other end is connected to the moving plate. By converting the rotational motion of the motor into the linear reciprocating motion of the moving plate, combined with the three-dimensional drying effect of the drying assembly, dynamic and uniform drying of the wooden box is achieved.

[0010] Preferably, the drying assembly further includes an air duct, which is arranged around the outer periphery of the fan and extends toward the moving plate. Its function is to gather and guide the airflow generated by the fan, so that it acts more concentratedly on the surface of the wooden box, thereby improving the efficiency of air drying.

[0011] Preferably, the motor is fixedly installed on one side of the outer wall of the protective cover. This external installation layout not only makes the overall structure more compact and facilitates the transmission connection with the gear, but also helps the motor to dissipate heat during operation, ensuring its stable operation for a long time.

[0012] Preferably, the lower edge of the protective cover is supported on the mounting base to form a relatively enclosed drying space. This structural design helps to reduce heat loss during the drying process, improve energy efficiency, and maintain a stable temperature environment in the drying area.

[0013] Preferably, the connecting slider is fixedly connected to the side wall of the moving plate. This robust connection ensures that the linear motion of the rack can be transmitted to the moving plate without loss and with high precision, thus guaranteeing the smoothness and reliability of the reciprocating motion of the moving plate.

[0014] Preferably, the device further includes a conveyor belt, which is disposed on the workbench and its conveying end is connected to the moving plate, for automatically conveying the wooden boxes to be processed onto the moving plate, and is a basic component for realizing an automated production process.

[0015] Preferably, in addition to the conveyor belt, the device also includes a brush, which is positioned above the conveyor belt and can automatically apply the anti-corrosion coating before the wooden crates are sent into the drying area, thus forming a complete automated production line from coating to drying.

[0016] Preferably, the reciprocating components are symmetrically arranged on both sides of the moving plate. By setting a set of drive mechanisms on each side of the moving plate and making them run synchronously, a more stable and balanced driving force can be provided to the moving plate, effectively preventing deflection or malfunctions that may occur when driving on one side, and further improving the operational stability of the equipment.

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

[0018] 1. This utility model solves the problems of uneven heating and low drying efficiency of wooden boxes caused by fixed drying in the prior art by setting a reciprocating movable plate and cooperating with the upper blowing structure and the lower heating structure. It achieves the technical effect of making the wooden box receive heat and airflow evenly during the drying process, thereby improving the coating drying quality and drying speed.

[0019] 2. This utility model solves the problems of manual handling, process separation, and low production efficiency in traditional wooden box anti-corrosion treatment by setting up a conveyor belt and a brush, and integrating the brushing process with the drying process. It achieves the technical effect of realizing fully automated operation from brushing to drying, reducing labor costs and improving overall production efficiency.

[0020] 3. This utility model solves the problems of high energy consumption and serious heat loss in open drying by setting a protective cover above the moving plate and embedding the heating structure in the mounting base. It achieves the technical effect of forming a compact semi-enclosed drying space, effectively gathering heat and airflow, thereby reducing energy consumption and saving production space.

[0028] 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.

[0029] Please refer to Figures 1 to 5 This utility model provides a wooden box anti-corrosion coating device, which aims to solve the problems of slow drying speed and uneven drying of coating after wooden box coating in the prior art.

[0030] like Figure 1 As shown, the anti-corrosion coating device for wooden boxes is built on a workbench 1. It mainly includes a conveying coating area and a reciprocating drying area. The conveying coating area includes a conveyor belt 2 and a coater 3. The reciprocating drying area includes a mounting base 503, a movable plate 601 slidably mounted on the mounting base 503, a protective cover 4 covering the movable plate 601, an integrated drying component 5, and a reciprocating component 6 for driving the movable plate 601. The conveying end of the conveyor belt 2 is connected to the movable plate 601 to automatically convey the wooden boxes coated by the coater 3 to the movable plate 601 for drying.

[0031] Please refer to Figure 3 and Figure 4 The drying assembly 5 consists of an upper blowing structure and a lower heating structure. The upper blowing structure includes a fan 501 installed on the inner wall of the protective cover 4 and an air guide 502 arranged around the outer periphery of the fan 501. The air guide 502 gathers the airflow generated by the fan 501 and guides it to the moving plate 601. The lower heating structure is a serpentine heating tube 504 sealed inside the mounting base 503. The serpentine heating tube 504 is used to heat the moving plate 601 and the wooden box above it from bottom to top.

[0032] Please refer to Figure 4 and Figure 5The reciprocating assembly 6 is a precision transmission mechanism that converts rotary motion into linear reciprocating motion. It includes a motor 602 as a power source, a gear 603 fixedly connected to the output end of the motor 602, a rack 604 meshing with the gear 603, a fixed bracket 605 fixed to the upper surface of the mounting base 503, and a connecting slider 607. The fixed bracket 605 has a sliding groove 606 for guiding and limiting. The connecting slider 607 is correspondingly provided with a sliding part that matches the sliding groove 606 and slides into the sliding groove 606. One end of the connecting slider 607 is fixedly connected to the rack 604, and the other end is fixedly connected to the side wall of the moving plate 601. It can stably and accurately convert the rotary motion of the motor 602 into the linear reciprocating motion of the moving plate 601.

[0033] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0034] To automate the production process, the conveyor belt 2 is set on the workbench 1, with its conveying direction perpendicular to the reciprocating motion direction of the moving plate 601, and its conveying end is connected to the upper surface of the moving plate 601 in height so as to transfer the wooden box smoothly. The paint brush 3 is straddling the conveyor belt 2 and located in front of the moving plate 601, and is used to complete the automatic painting operation before the wooden box enters the drying area.

[0035] To make the overall structure more compact and stable, the motor 602 is fixedly mounted on one side of the outer wall of the protective cover 4 by bolts or brackets. This layout not only saves space but also facilitates the heat dissipation of the motor 602 itself. At the same time, in order to enhance the airtightness of the drying space, the lower edge of the protective cover 4 is supported on the top surface of the mounting base 503, and a sealing strip can also be set between the two.

[0036] To ensure the strength and reliability of the transmission connection, the connecting slider 607 is preferably fixedly connected to the side wall of the moving plate 601 by welding or multiple bolts to ensure that it will not loosen or shift relative to the other side during long-term reciprocating motion.

[0037] As an optimization scheme for the stability of the drive system, the reciprocating component 6 can be symmetrically arranged on both sides of the moving plate 601, that is, a drive mechanism is set on each of the left and right sides of the moving plate 601, and the motors 602 on both sides run synchronously. By driving on both sides, a more stable and balanced driving force is provided to the moving plate 601, effectively avoiding the deflection or jamming that may occur when driving on one side.

[0038] Working principle: When the wooden crate needs to be treated for corrosion prevention, the crate is first carried by the conveyor belt 2, passes under the brush 3 for automatic coating, and is then transferred to the moving plate 601 and enters the drying area covered by the protective cover 4. At this time, the drying component 5 and the reciprocating component 6 start simultaneously. In the drying component 5, the fan 501 blows air from top to bottom, and the serpentine heating tube 504 provides heat from bottom to top, forming a three-dimensional drying environment. At the same time, the motor 602 of the reciprocating component 6 drives the rack 604 to reciprocate within the fixed bracket 605 through the gear 603, and drives the moving plate 601 carrying the wooden crate to reciprocate stably through the connecting slider 607 sliding in the sliding slot 606. Through this dynamic reciprocating motion, it is ensured that the wooden crate can receive airflow and heat evenly at every position in the drying area, thereby solving the problem of uneven heating caused by static drying and improving the drying speed of the coating and the final coating quality.
