Description

Technical Field

[0001] This application relates to the technical field of heating devices, and in particular to a thin-film heating device. Background Technology

[0002] In some equipment, it is necessary to perform stable heat preservation on certain key components to maintain a relatively stable temperature range, which facilitates stable operation of the equipment, provides relevant data, and makes it easier for operators to carry out subsequent operations.

[0003] In related technologies, operators typically install a heating element on the workpiece. The heat source is used to heat the area, thereby maintaining a certain temperature range around the workpiece to facilitate stable operation.

[0004] Regarding the aforementioned technologies, using a heat source can easily lead to excessively high local temperatures, while the temperature in other areas may be lower, resulting in poor overall temperature balance. This is not conducive to the insulation of the workpiece and thus affects the detection of relevant data. Utility Model Content

[0005] In order to better keep the workpiece warm, this application provides a thin-film heating device.

[0006] This application provides a thin-film heating device, which adopts the following technical solution:

[0007] A thin-film heating device includes an armored heater, which comprises a thin-film heating element, a thin-film heating band, an armored heating wire, and a metal-cased wire-wound resistor. The thin-film heating element is attached to a workpiece. The thin-film heating band and the armored heating wire are both inserted through the thin-film heating band and fixedly connected to it. The metal-cased wire-wound resistor and the armored heating wire are fixedly connected.

[0008] By adopting the above technical solution, based on the principle of Joule effect, electrical energy is converted into heat energy, so that the controlled object is maintained within the predetermined temperature range. In conjunction with the temperature control system, a temperature control accuracy of ±2℃ can be achieved.

[0009] Optionally, a fixing device is also included, which includes a fixing cylinder. The inner cavity of the fixing cylinder is provided with a fixing rod and a supporting device. The fixing rod is used to support the workpiece. The supporting device includes a supporting ring. The supporting ring is circumferentially distributed with telescopic rods and abutment plates. One end of the telescopic rod is rotatably connected to the supporting ring. The abutment plate abuts against the thin-film heating element.

[0010] By adopting the above technical solution, the fixed cylinder provides support for the installation of the fixed rod and support device. The fixed rod provides support for the installation of the workpiece and prevents it from shaking. The operator then adjusts the angle of the telescopic rod so that the abutment plate can abut against the thin-film heating belt, thereby performing the corresponding heating operation on the workpiece.

[0011] Optionally, multiple support devices are provided, and the multiple support devices are arranged sequentially in the vertical direction; the support ring can slide along the axial direction of the fixed cylinder.

[0012] By adopting the above technical solution, multiple support devices are provided, thereby increasing the number of abutment plates and enhancing the support effect of the abutment plates on the thin-film heating element, thus better heating the workpiece.

[0013] Optionally, the top of the fixed rod is provided with multiple support rods, which are rotatably connected to the fixed rod and are used to support the workpiece.

[0014] By adopting the above technical solution, the support rod can provide support for the workpiece. The operator only needs to rotate the support rod so that the end of the support rod abuts against the side wall of the workpiece, thereby providing a stable support effect for the workpiece.

[0015] Optionally, the end of the support rod is provided with an abutment piece, and the abutment piece and the support rod are rotatably connected.

[0016] By adopting the above technical solution, the setting of the abutment piece can further increase the contact area between the support rod and the workpiece, and can better provide a more stable support effect for the workpiece, preventing the workpiece from shaking.

[0017] Optionally, an elastic pad is provided on the end face of the abutment piece away from the support rod, and the elastic pad and the abutment piece are fixedly connected.

[0018] By adopting the above technical solution, the elastic pad can fill the gap between the abutment plate and the workpiece, thereby increasing the effective contact area between the abutment plate and the workpiece and providing better positioning for the workpiece.

[0019] Optionally, a rack is fixedly connected to the inner cavity of the fixed cylinder, and each of the support rings is equipped with a gear. The gear and the support ring are rotatably connected, and the gear and the rack mesh.

[0020] By adopting the above technical solution, the operator drives the gear at the support ring to rotate, the gear meshes with the rack, and then drives the gear to slide along the long side of the rack, so that the height of the gear changes, thereby changing the position of the support ring.

[0021] Optionally, the support ring is fixedly connected to a wire clip.

[0022] By adopting the above technical solution, the support ring provides support for the installation of the wire clip. The wire clip is fixed to the support ring, which in turn provides a limit to the installation of related circuits in the armored heater, thereby giving the circuits in the fixed cylinder a certain arrangement direction and improving neatness.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting up armored heaters, precise temperature control and heating of the workpiece can be achieved;

[0025] 2. By setting up a fixing device, the position of the workpiece can be precisely controlled;

[0026] 3. By setting up a support device, the armored heater can be precisely controlled. Attached Figure Description
