Description

Technical Field

[0001] The utility model relates to the technical field of plate heat exchanger production equipment, in particular to a vehicle-mounted wireless glue injection machine for air plate heat exchangers. Background Art

[0002] The air plate heat exchanger is a high-efficiency heat exchanger made of a series of metal plates with certain shape support points. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. The plate heat exchanger is an ideal equipment for air-to-air heat exchange. It has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, diversified airflow direction, small footprint, wide application, and long service life. Under the same pressure loss, its heat transfer coefficient is higher than that of the heat pipe heat exchanger, and the heat recovery rate can be as high as 90% or more.

[0003] In the existing process, it is necessary to fill the channel gap of the plate heat exchanger with glue for sealing, but the current glue injection machines for plate heat exchangers are usually fixed, and each workstation has a glue injection machine dedicated to gluing one model of product, and they are all powered by a wired connection to the mains. Therefore, it is difficult to move it to a different workstation, and when the glue injection machine at a workstation fails, the workstation can only be stopped, and the remaining idle workstations cannot be moved to replace the glue injection machine used for glue injection of other models of plate heat exchangers. In addition, different models of plate heat exchangers have different lengths and heights, resulting in different glue injection heights. The glue injection height of the dedicated glue injection machine cannot be adjusted, which also makes it inapplicable to other workstations. Utility Model Content

An air compressor 4, a glue dispensing pressure cylinder 5 and a driving mechanism 7 for installing a glue dispensing valve 8 are installed on a lifting platform 3 arranged on a frame 1, and power is supplied by a battery 6 without the constraints of a power cord, so that the glue injection machine of the utility model can be moved to any workstation, and since the driving mechanism 7 for installing the glue dispensing valve 8 is installed on the lifting platform 3, its glue injection height can be adjusted, and it can adapt to the glue injection of various models of plate heat exchangers; the PLC controller 2 can be used to set the glue injection trajectory of the glue dispensing valve 8 (that is, the movement of the driving mechanism 7 and the lifting platform 3), as well as the glue output speed and pressure (controlling the opening size of the pressure glue cylinder and the glue dispensing valve 8).

[0023] See also Figures 1 to 4Preferably, the driving mechanism 7 includes a mounting frame 71 and a driving assembly 72. The mounting frame 71 is mounted on the edge of the upper surface of the lifting platform 3. The driving assembly 72 is mounted on the mounting frame 71.

[0030] The utility model has the following working principle:

[0031] The air compressor 4, PLC controller 2, dispensing valve 8, lifting platform 3 and stepper motor 724 of driving mechanism 7 are powered by lithium batteries; according to production needs, the frame 1 is pushed by the push rod 9 (the wheels of the frame 1 can be locked), so that the glue injection machine of the utility model moves to a suitable glue injection position, and the glue head fixing universal seat 74 is adjusted to adjust the dispensing valve 8 to a suitable glue outlet angle; then the glue outlet speed, glue outlet pressure, and the running track of the dispensing valve 8 (the vertical movement of the lifting platform 3 and the horizontal movement of the driving mechanism 7) are set by the PLC controller 2, and the glue injection can be started after the setting is completed.
