Description

Technical Field

[0001] The utility model relates to the field of plastic-steel profile production equipment, in particular to heat-resistant temperature-regulating heat treatment equipment for plastic-steel profiles. Background Art

[0002] Plastic-steel profiles are PVC profiles used to make doors and windows. Because doors and windows made solely of PVC profiles are not strong enough, steel is usually added to the mold cavity to enhance the firmness of the doors and windows. Therefore, plastic doors and windows made with steel added inside the profile are usually called plastic-steel doors and windows.

[0003] Existing plastic-steel door and window profiles generate a lot of internal stress during production. In the hot summer, the profiles will shrink and deform after absorbing heat, causing weld corners to crack and even cause the entire profile to crack and fall apart.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Summary of the Invention

[0005] In order to improve the technical problem in the prior art that a large amount of internal stress exists in the plastic-steel door and window profiles, which shrinks and deforms after absorbing heat in hot summer weather, leading to weld cracking, the utility model provides a heat-resistant and temperature-controlled heat treatment device for plastic-steel profiles. The heat-resistant and temperature-controlled heat treatment device for plastic-steel profiles comprises: a frame; a heat treatment box mounted on the frame; a partition mounted in the heat treatment box, the partition being configured to divide the heat treatment box into a plurality of heating chambers, each of the heating chambers being respectively mounted with a resistance wire plate, and the resistance wire plates in each heating chamber being individually controlled; a conveying structure mounted on the frame, and comprising a rotatable driving shaft mounted on the frame, a driven shaft arranged opposite to the driving shaft and mounted on the frame, a mesh belt mounted on the driving shaft and the driven shaft, and a driving motor for driving the driving shaft to rotate.

[0006] In the utility model, a heat-resistant temperature-controlled heat treatment equipment for plastic-steel profiles includes a frame, a heat treatment box and a conveying structure. The frame is used to install the heat treatment box and the conveying structure. The heat treatment box is divided into multiple heating chambers by partitions, and each heating chamber is equipped with a separately controlled resistance wire plate. By energizing the resistance wire plate, the resistance wire plate generates heat and transfers heat to the air in the heating chamber, thereby heating the plastic-steel profile. Each resistance wire plate is controlled separately, so that the temperature of each heating chamber is controlled separately, which facilitates the preheating, heating and cooling processes of the plastic-steel profile. The conveying structure is installed on the frame and includes a drive motor, an active shaft, a driven shaft and a mesh belt. The plastic-steel profile is placed on the mesh belt, and the active shaft is driven to rotate by the drive motor, thereby driving the mesh belt to pass through the heat treatment box. Through the above-mentioned setting, the utility model provides a heat-resistant temperature-controlled heat treatment equipment for plastic-steel profiles by setting partitions in the heat treatment box to form multiple heating chambers, the temperature of each heating chamber is controlled separately, and the plastic-steel profiles are driven through the heat treatment box by a mesh belt, thereby facilitating the preheating, heating and cooling processes of the plastic-steel profiles.

[0007] Furthermore, the partition is detachably installed in the heat treatment box.

[0008] Furthermore, the heat treatment box includes side walls installed on the frame and a top wall connected to the side walls; a positioning groove matching the partition is opened on the side wall, and a taking groove matching the partition is opened on the top wall.

[0009] Furthermore, an asbestos sealing plate is arranged at the taking groove and is hingedly connected to the top wall.

[0010] Furthermore, air curtain doors that can form heat-insulating air curtains are arranged at both ends of the heat treatment box.

[0011] Furthermore, an avoidance groove for avoiding the plastic-steel profile to pass through is opened on the partition, and an adjustment plate for adjusting the size of the avoidance groove is slidably arranged on the partition.

[0012] Furthermore, the driving motor is mounted on the frame, and a driving gear is provided on the driving shaft of the driving motor, and a driven gear is provided on the driving shaft; the driving gear and the driven gear are connected via a driving chain.

[0013] Furthermore, leveling feet are provided below the frame.

[0014] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0015] The heat treatment chamber is divided into multiple heating chambers by partitions, each housing an individually controlled resistance wire plate. When the resistance wire plates are energized, they generate heat and transfer it to the air within the chamber, thereby heating the plastic-steel profile. Each resistance wire plate is individually controlled, allowing for independent temperature control of each heating chamber, facilitating preheating, heating, and cooling of the plastic-steel profile. The conveying mechanism is mounted on a frame and comprises a drive motor, a driving shaft, a driven shaft, and a mesh belt. The plastic-steel profile is placed on the mesh belt, which is then driven by the drive motor to rotate the driving shaft, thereby driving the mesh belt through the heat treatment chamber.
