Description

Technical Field

[0001] The utility model relates to the technical field of glue pouring equipment, in particular to a constant temperature curing tunnel furnace. Background Art

[0002] The motor stator needs to be glued during the production and assembly process. After glue filling, the motor stator has the advantages of waterproof, fast heat dissipation, dustproof and shockproof. The motor glue filling was initially done manually, and the process was relatively cumbersome and could not guarantee the consistency of the glued products. Therefore, glue filling automation has become an industry development trend. The glue-filled motor stator needs to be kept at a constant temperature in the oven to make the glue have good fluidity, thereby ensuring the quality and comprehensiveness of the glue filling and meeting the glue filling requirements of the product. How to effectively utilize the heat in the oven, reduce heat energy loss, and at the same time maintain the ambient temperature required for the glue to flow, therefore, a constant temperature curing tunnel furnace is needed. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a constant temperature curing tunnel furnace to solve the problem of reducing heat energy loss in the oven in the prior art.

[0004] To achieve the above-mentioned and other related purposes, the present invention provides the following technical solutions:

[0005] A constant temperature curing tunnel furnace, comprising:

[0006] The base is a hollow base, the side walls of the base are provided with guard plates, the bottom of the base is open, and the bottom of the base is provided with supporting legs, and open side doors are provided at both ends of the base;

[0007] A constant temperature chamber is arranged on the upper side of the base, an insulation board is arranged at the bottom of the constant temperature chamber to separate the bottom of the constant temperature chamber from the base, a conveyor chain is arranged on the insulation board, a material plate is arranged on the conveyor chain, and a constant temperature component is arranged on the top of the constant temperature chamber to keep the temperature inside the constant temperature chamber constant.

[0008] To implement the above technical solution, protective plates are provided on the side walls of the base to improve the thermal insulation effect of the base. The bottom of the base is set to be open, and open side doors are provided at both ends of the base to maintain the ventilation effect inside the base. An insulation board is provided at the bottom of the constant temperature chamber to prevent the temperature inside the constant temperature chamber from being lost from the bottom of the constant temperature chamber. A conveyor chain is provided on the insulation board, and the stator after glue filling is conveyed to the constant temperature chamber for heating treatment by means of a material plate, so that the glue has better fluidity in the stator, thereby achieving sufficient glue filling of the stator, and the constant temperature component keeps the temperature inside the constant temperature chamber constant.

[0009] In one embodiment of the present invention, both ends of the constant temperature chamber are open, and constant temperature doors are arranged at both ends of the constant temperature chamber. A lifting drive member is provided on the upper side of the constant temperature chamber. The constant temperature door is provided at the movable end of the lifting drive member and moves up and down with the movable end of the lifting drive member to open or close the constant temperature chamber.

[0010] To implement the above technical solution, the thermostatic chamber is open at both ends, which can facilitate the conveyor chain to transport the stator after the glue filling process. The setting of the thermostatic chamber door can close the thermostatic chamber, thereby reducing the heat loss in the thermostatic chamber and improving the thermal energy utilization rate in the thermostatic chamber.

[0011] In one embodiment of the present invention, two groups of door stop plates are symmetrically provided on both sides of the constant temperature door, and the two groups of door stop plates are both right-angle plates. The constant temperature door slides with the two groups of door stop plates.

[0012] The above technical solution is implemented by symmetrically arranging two sets of door limit plates on both sides of the constant temperature cabin door, and the constant temperature cabin door and the two sets of door limit plates slide together. In this way, when the lifting drive component drives the constant temperature cabin door to move up and down, it can limit the lifting movement of the constant temperature cabin door, thereby ensuring the stability of the constant temperature cabin door.

[0013] In one embodiment of the present invention, a material belt driving component is provided on the lower side of the heat insulation board, a conveying frame is provided on both sides of the heat insulation board, a tensioning frame is provided between the two ends of the conveying chain and the conveying frame, a tensioning slider is slidably connected to the tensioning frame, a conveying gear supporting the conveying chain is provided on one side of the tensioning slider, and a tensioning drive assembly is provided on one side of the tensioning frame to adjust the position of the tensioning slider along the length direction of the tensioning frame.

[0014] To implement the above technical solution, the position of the conveying gear along the length direction of the tensioning frame can be adjusted through the tensioning slider slidably connected to the tensioning frame, thereby adjusting the tension of the conveyor chain to meet usage requirements.

[0015] In one embodiment of the present invention, the tensioning drive assembly includes a tensioning stud arranged on the tensioning frame along the length direction of the conveying frame, and the tensioning slider is provided at a movable end of the tensioning stud.

[0016] To implement the above technical solution, the tensioning stud is threadedly connected to the tensioning frame, which in turn drives the tensioning slider to adjust its position along the length direction of the conveyor frame, thereby adjusting the tensioning degree of the conveyor chain. A tensioning guide rail is provided on the tensioning frame, and the tensioning slider is slidably assembled on the tensioning guide rail. The tensioning guide rail is used to limit the moving direction and position of the tensioning slider.

[0017] In one embodiment of the present invention, the constant temperature component includes a temperature control cabin, an air inlet is configured at the bottom of the temperature control cabin, and air outlets are configured at both ends of the temperature control cabin. A blower is arranged inside the temperature control cabin and above the air inlet. The air inlet and the blower are provided with heating pipes. The blower discharges the airflow heated by the heating pipe at the air inlet from the air outlets at both ends of the temperature control cabin.

[0018] To implement the above technical solution, a blower is used to discharge the gas at the air inlet from the air outlets at both ends of the temperature control chamber. Under the action of the blower, the air flow velocity at the air outlet is fast enough, and the Coanda effect will not occur. The air flow at the air outlet can directly impact the surface of the glue-filled workpiece below. The heating tube can heat the gas at the air inlet end of the blower, so that the temperature of the gas discharged at the air outlet maintains the required temperature of the oven. The gas at the air inlet end of the blower is also the airflow from the inside of the oven. In this way, the air flow at the air inlet end and the air outlet forms a reflux state, so that the gas can maintain a better constant temperature state. The heating effect of the heating tube is better, so that the entire oven can maintain a better constant temperature state.

[0019] In one embodiment of the present invention, an air outlet compartment is arranged between the rear side of the air outlet and the temperature control compartment. The air outlet compartment is a right-angled trapezoidal air outlet compartment with an opening facing downward, and the oblique side of the air outlet compartment gradually slopes downward away from the temperature control compartment.

[0020] To implement the above technical solution, the hypotenuse of the right-angled trapezoidal air outlet cabin is gradually tilted downward away from the temperature control cabin, so that the airflow output by the blower can be blown directly to the surface of the glue-filled workpiece, ensuring the hot air's thermal drying effect on the glue-filled workpiece.

[0021] In one embodiment of the present invention, an air outlet channel is configured between the air outlet compartment and the temperature control compartment, and the air outlet channel is provided on a right-angled side of the air outlet compartment that is perpendicular to the air outlet direction of the air outlet.

[0022] By implementing the above technical solution, the air outlet channel can guide the gas in the temperature control chamber into the air outlet chamber, and discharge the heated gas from the air outlet chamber.

[0023] In one embodiment of the present invention, the constant temperature components are arranged in multiple groups along the length direction of the base platform in the constant temperature chamber.

[0024] By implementing the above technical solution and setting up multiple groups of constant temperature components, it can be ensured that the constant temperature chamber on the entire base can maintain a good constant temperature state.

[0025] As described above, a constant temperature curing tunnel furnace of the present invention has the following beneficial effects: by arranging a protective plate on the side wall of the base, the thermal insulation effect of the base can be improved; the bottom of the base is set to be open, and open side doors are set at both ends of the base to maintain the ventilation effect inside the base; by arranging a heat insulation board at the bottom of the constant temperature chamber, the temperature inside the constant temperature chamber can be prevented from being lost from the bottom of the constant temperature chamber; a conveyor chain is arranged on the heat insulation board, and the stator after glue filling is conveyed to the constant temperature chamber for heating treatment by using a material plate, so that the glue has better fluidity in the stator, and the stator is fully glued, and the constant temperature component keeps the temperature inside the constant temperature chamber constant.
