Description

Technical Field

[0001] This utility model relates to the technical field of PB oven equipment, specifically to a PB oven that provides even baking. Background Technology

[0002] In the existing use of PB ovens, uneven heating during product conveyor baking can easily affect product quality. Furthermore, poor fit of components such as support guide rollers can lead to unstable product conveying, further interfering with baking uniformity. This is particularly problematic when baking the PR adhesive on copper foil surfaces, where the PR adhesive on both sides of the copper foil edges often exhibits unsatisfactory baking results. This manifests as insufficient curing or over-baking of the adhesive layer in the edge areas, resulting in a significant quality difference compared to the central area. This is because heat is easily lost at the edges of the copper foil, and traditional heating structures struggle to precisely compensate for heat loss in the edge areas. Therefore, we propose a PB oven for more uniform baking. Utility Model Content

[0003] In view of the problems existing in the PB oven that provides uniform baking, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide a PB oven with uniform baking, which solves the problem that in the use of existing PB ovens, uneven heating during product conveyor baking can easily affect product quality, and poor fit of components such as support guide wheels can lead to unstable product conveying, further interfering with baking uniformity. In particular, when baking PR adhesive on the surface of copper foil, the baking effect of PR adhesive on both sides of the copper foil edge is often unsatisfactory, mainly manifested as insufficient curing or over-baking of the adhesive layer in the edge area, with obvious quality differences from the middle area. This is because heat is easily lost at the edge of the copper foil, and traditional heating structures are difficult to accurately supplement the heat in the edge area.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A PB oven for even baking includes an oven body, a hot air guide duct, and a product belt. Multiple support columns are fixedly installed at both ends inside the oven body. Support plates are fixedly installed on the surfaces of the support columns. Shock-absorbing springs are fixedly installed on the tops of the support plates. Fixing blocks are fixedly installed on the tops of the shock-absorbing springs, and these fixing blocks are slidably connected to the support columns. Supporting guide wheels are rotatably arranged between two opposing fixing blocks on one side. An inlet and an outlet are respectively provided on both sides of the oven body. A product belt runs through the inlet and outlet, and the product belt is located on top of the supporting guide wheels. A hot air guide duct is fixedly installed between the two sides inside the oven body.

[0007] Preferably, a heating wire is fixedly installed on one side of the hot air guide duct, a fan is fixedly installed inside the hot air guide duct located on the side of the heating wire, and multiple guide holes are provided through the bottom of the hot air guide duct.

[0008] Preferably, a bidirectional lead screw and a slide rod are respectively provided between the two ends on both sides of the oven body, and the bidirectional lead screw is rotatably connected to the oven body. The surfaces of the bidirectional lead screw and the slide rod are provided with mounting blocks, and the mounting blocks on the surface of the bidirectional lead screw are threadedly connected to the bidirectional lead screw. The bottom of the multiple mounting blocks is fixedly installed with fixing rods, and heating strips are fixedly installed at the bottom of the two fixing rods at one end.

[0009] Preferably, one end of the oven body is hinged with multiple oven doors, and heating plates are provided at the top and bottom of the inner side of the oven body.

[0010] Preferably, multiple high-precision infrared temperature sensors are fixedly installed at one end of the multiple oven doors and the interior of the oven body.

[0011] Preferably, a motor is fixedly installed at one end of the oven body, and the output end of the motor is fixedly connected to one end of a bidirectional lead screw.

[0012] Preferably, a controller is fixedly installed on the surface of one side of the box door, and a control panel is fixedly installed on the surface of the controller. The controller is electrically connected to the control panel, heating wire, fan, heating plate, motor and multiple high-precision infrared temperature sensors.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. In this utility model, the support guide wheel, in conjunction with the support column and the shock-absorbing spring, effectively buffers the vibration during the conveying process, reduces the fluctuation of the product belt conveying, and provides a stable conveying foundation for uniform baking, avoiding local baking differences caused by unstable conveying. At the same time, the symmetrical heating plates at the top and bottom, combined with the hot air circulation of the hot air guide duct, form a multi-dimensional heating system to ensure uniform heating in the middle area of ​​the product belt; the adjustable heating strip can accurately supplement the heating of the copper foil edge, solve the problem of edge heat loss, avoid insufficient curing or over-baking of the PR adhesive at the edge, and make the overall PR adhesive baking effect of the copper foil consistent.

[0015] 2. This utility model uses a high-precision infrared temperature sensor to comprehensively monitor the temperature inside the oven. The controller adjusts the power of each heating component and the status of the fan in real time based on the monitoring data, realizing intelligent and precise temperature control. This significantly reduces product quality problems caused by temperature runaway in traditional ovens. At the same time, the position of the heating strip can be flexibly adjusted by a motor-driven bidirectional lead screw to adapt to copper foil of different widths. The combination of the controller and control panel makes the operation simple and intuitive, and allows for quick setting of baking parameters according to different product needs, improving the versatility of the equipment and production efficiency.
