Description

Technical Field

[0001] This utility model relates to the field of metal product processing equipment technology, and more specifically, to an intelligent temperature-controlled drying oven for surface treatment of metal products. Background Technology

[0002] After surface treatment (such as electroplating, spraying, phosphating, etc.), metal products need to be dried to remove residual moisture or chemical agents on the surface in order to ensure the adhesion, corrosion resistance and appearance quality of the surface treatment layer.

[0003] Existing drying ovens mostly employ a single- or double-sided open-access structure. When metal products are opened to remove or place them, the high-temperature hot air inside the drying chamber escapes rapidly, causing a sudden temperature drop of 10-30°C. Reheating requires a significant amount of electrical energy, and temperature fluctuations can lead to uneven curing of the coating on the metal product surface, resulting in cracks or bubbles, particularly affecting the surface treatment precision of precision metal parts. Therefore, we propose an intelligent temperature-controlled drying oven for metal product surface treatment. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide an intelligent temperature-controlled drying oven for surface treatment of metal products, so as to solve the technical problem of temperature loss when taking metal products out of the current drying oven and affecting the continuous drying effect.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an intelligent temperature-controlled drying oven for surface treatment of metal products, including a drying oven for drying metal products and a storage box for alternately holding metal products for drying; The drying oven has an internal structure with a drying chamber for moving the storage box. The inner sides of the drying chamber are provided with sliding grooves. The side walls of the drying oven are provided with a driving component for moving the storage box. Both sides of the drying oven are provided with sealing components for sealing the storage box. The storage box includes a box body with a cavity extending through the top, bottom and sides of the box body. Several rotatable support rods are provided between the inner sides of the two sides of the box body, and the gaps between adjacent support rods are used to support metal products.

[0006] This utility model features a storage box for drying metal products by alternating placement of the storage box. After one side is dried, it can be moved out by the operation of the drive component, allowing the storage box for the other metal products to enter the drying chamber. During the alternation process, the cavity of the box can be sealed by the cooperation of the sealing component, effectively preventing the internal heat from escaping, maintaining a uniform temperature inside the drying chamber, reducing energy consumption, and maintaining the stability of the drying quality of the metal products.

[0007] Preferably, one end of the support rod penetrates the side wall of the box, and a driven gear is provided at this end of the support rod, and a first rack that meshes with the driven gear is provided at the bottom of the slide groove on the same side.

[0008] Preferably, the driving component includes a motor disposed on the outside of the drying chamber, the output end of the motor is provided with a driving gear located in a slide groove on one side, and the side of the box body away from the driven gear is provided with a second rack that meshes with the driving gear.

[0009] Preferably, electric heating lamps are provided at both the bottom and top of the drying chamber, and the distance between the electric heating lamps on both sides and the surface of the metal product is the same. A protective net for protecting the electric heating lamps is also provided at the bottom of the drying chamber.

[0010] Preferably, the sealing element includes two sealing plates that close the cavity of the box, with the bottom sealing plate disposed on the outer surface of the drying chamber, and the top surface of the top sealing plate disposed with an electric push rod connected to the outer surface of the drying chamber.

[0011] Preferably, the top surface of the bottom sealing plate is provided with a limiting rod that penetrates the top sealing plate, and the wall of the limiting rod is provided with a support ring for supporting the top sealing plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The storage box of this utility model, which dries metal products by alternating placement, can be moved out by the operation of the drive component after one side is dried, so that the storage box containing the metal products on the other side can enter the drying chamber. During the alternation process, the cavity of the box can be sealed by the cooperation of the sealing component, which can effectively prevent the internal heat from leaking out, maintain the temperature inside the drying chamber evenly, reduce power consumption, and maintain the stability of the drying quality of the metal products.

[0013] 2. This utility model also achieves a double advantage of uniform drying by using a "rotatable support rod + cavity through-hole design" for the storage box, combined with symmetrically arranged electric heating lamps at the top and bottom of the drying chamber: On the one hand, the support rod meshes with the first rack through a driven gear and rotates synchronously with the movement of the storage box, causing the metal products to flip over and avoiding drying dead corners caused by partial obstruction; on the other hand, the cavity through-hole structure and the symmetrical layout of electric heating lamps form an upper and lower convection channel, with the electric heating lamps spaced evenly with the metal products, resulting in more comprehensive heat coverage, significantly shortening the drying cycle, and ensuring that the surface coatings, anti-rust layers, and other treatment layers of the metal products dry evenly, reducing quality problems such as cracking and peeling.

[0016] like Figures 1 to 7 As shown, this utility model relates to an intelligent temperature-controlled drying oven for surface treatment of metal products, including a drying oven 1 for drying metal products and a storage box 2 for alternately holding and drying metal products. The internal structure of the drying oven 1 has a drying chamber 101 for moving the storage box 2. The inner sides of the drying chamber 101 are provided with sliding grooves 102. The side walls of the drying oven 1 are provided with driving components 3 for moving the storage box 2. Both sides of the drying oven 1 are provided with sealing components 4 for sealing the storage box 2. The drying chamber 101 is a rectangular sealed cavity with a heat insulation layer (such as aluminum silicate fiber cotton) on the inner wall to reduce heat loss and ensure temperature uniformity in the cavity (temperature difference ≤ ±5℃). The inner wall of the cavity has sliding grooves 102 on both sides that match the storage box 2 (the original text implies the structure, which will be deduced in conjunction with the subsequent rack and pinion configuration). The width of the sliding grooves 102 is 0.5-1mm larger than the side thickness of the storage box 2 to ensure that the storage box 2 can slide smoothly, while avoiding excessive gaps during sliding that could lead to heat leakage. The length of the drying cavity 101 must be sufficient to allow the storage box 2 to fully enter.

[0017] The storage box 2 includes a box body 201 with a cavity extending through the top, bottom and sides of the box body 201. Several rotatable support rods 202 are arranged between the inner sides of the two sides of the box body 201, and the gaps between adjacent support rods 202 are used to support metal products. Multiple metal products can be placed by the support of the rotatable support rods 202. Among them, tubular metal products can rotate during rotation and friction, thereby achieving the effect of drying by changing the surface and reducing the drying dead corners.

[0018] In an embodiment of this utility model, one end of the support rod 202 penetrates the side wall of the box 201, and a driven gear 203 is provided at this end of the support rod 202. A first rack 103 that meshes with the driven gear 203 is provided at the bottom of the slide groove 102 on the same side. The support rod 202 can rotate during the movement of the box 201 by the cooperation between the driven gear 203 and the first rack 103.

[0019] In an embodiment of this utility model, the driving component 3 includes a motor 301 disposed on the outside of the drying box 1. The output end of the motor 301 is provided with a driving gear 302 located in a sliding groove 102 on one side. The side of the box body 201 away from the driven gear 203 is provided with a second rack 204 that meshes with the driving gear 302. The motor 301 is selected as a stepper motor or a servo motor. The power is set according to the weight of the storage box 2 (including metal products), usually 0.5-2kW. It has forward and reverse rotation functions and the speed is adjustable (5-10mm / s) to ensure that the storage box 2 moves smoothly and avoids collisions with metal products. The reciprocating movement of the storage box 2 is controlled by the cooperation of the driving gear 302 and the second rack 204.

[0020] In the embodiments of this utility model, electric heating lamps 104 are provided at both the bottom and top of the drying chamber 101, and the distance between the electric heating lamps 104 on both sides and the surface of the metal product is the same. A protective net 105 is also provided at the bottom of the drying chamber 101 to protect the electric heating lamps 104. The electric heating lamps 104 are existing technology structures. The temperature is adjusted to a suitable drying condition by the control system of the drying chamber 1. The protective net 105 can prevent foreign objects from damaging the electric heating lamps 104. The equal spacing can maintain stable heating and maintain the drying quality.

[0021] In an embodiment of this utility model, the sealing member 4 includes two sealing plates 401 that close the cavities of the box body 201. The bottom sealing plate 401 is disposed on the outer surface of the drying chamber 1, and the top surface of the top sealing plate 401 is provided with an electric push rod 404 connected to the outer surface of the drying chamber 1. The design of the sealing plate 401 can seal the cavity of the box body 201 when the storage box 2 is moved outward after drying, reducing the loss of heat inside the drying chamber 1. The electric push rod 404 controls the top sealing plate 401 to move upward, which can release the seal and facilitate the handling of metal products.

[0022] In an embodiment of this utility model, a limiting rod 402 penetrating the top sealing plate 401 is provided on the top surface of the bottom sealing plate 401, and a support ring 403 for supporting the top sealing plate 401 is provided on the rod wall of the limiting rod 402; this can increase the stability of the sealing plate 401 support and reduce the occurrence of position deviation.

[0023] Working Principle: This embodiment provides an intelligent temperature-controlled drying oven for surface treatment of metal products. During use, after the motor 301 in the drive unit 3 starts, its output drives the drive gear 302 in the slide groove 102 to rotate. The drive gear 302 meshes with the second rack 204 on the side of the storage box 2, converting rotational power into linear driving force, pushing the storage box 2 to move along the slide groove 102 in the drying chamber 101. Sealing elements 4 are provided on both sides of the drying oven 1. When one storage box 2 is moved into the drying chamber 101 for drying, the other storage box 2 can be used to place or remove metal products from the outside. The motor 301 drives the storage boxes 2 to alternately enter and exit the drying chamber 101, achieving continuous operation and improving drying efficiency. Several rotatable support rods 202 are provided inside the box body 201 of the storage box 2. Metal products are placed in the gaps between adjacent support rods 202. The support rods 202 provide multi-point support for the products, preventing direct contact between the product surface and the box body 201, ensuring smooth ventilation of the product surface. When the storage box 2 moves along the slide 102, the driven gear 203 at the end of the support rod 202 meshes with the first rack 103 at the bottom of the slide 102. The linear movement of the storage box 2 drives the driven gear 203 to rotate, which in turn drives the support rod 202 to rotate. During the rotation of the support rod 202, the metal products placed on it rotate synchronously, ensuring that all parts of the product surface receive drying heat evenly, avoiding problems such as insufficient drying or overheating in certain areas. Electric heating lamps 104 are installed at the top and bottom of the drying chamber 101, and the distance between the electric heating lamps 104 and the surface of the metal products is the same, ensuring that the upper and lower surfaces of the products are heated evenly. The equipment has a built-in intelligent temperature control system that monitors the temperature inside the drying chamber 101 in real time and maintains the set drying temperature by adjusting the power or working time of the electric heating lamps 104. The protective net 105 at the bottom of the drying chamber 101 can prevent metal products or debris from falling onto the surface of the electric heating lamps 104, avoiding damage to the electric heating lamps 104 or causing safety hazards, while not affecting heat penetration. When the surface of the metal products inside the storage box 2 is dried, the storage box 2 can be moved in the initial direction by the operation of the motor 301. During the movement, the surface of the storage box 2 will fit with the sealing part 4 on the other side, thereby sealing the cavity opening of the box body 201 and reducing the heat loss inside the drying chamber 1. When all the dried storage boxes 2 are moved out, the storage boxes 2 on the other side to be dried will re-close the drying chamber 1. Then, the top sealing plate 401 can be moved upward by the operation of the electric push rod 404, thereby releasing the seal of the storage box 2, taking out the dried metal products inside, and placing new metal products to be dried. The subsequent drying operation can be carried out by moving in the opposite direction, thereby keeping the internal temperature of the drying chamber 1 stable during the continuous drying process and reducing power consumption.
