Description

Technical Field

[0001] This utility model relates to the field of heat exchanger processing equipment, and in particular to a rapid grinding device for plate heat exchanger sealing strips. Background Technology

[0002] The sealing strip of a plate heat exchanger is a sealing material used to prevent fluid leakage inside the heat exchanger. It is usually made of materials such as rubber and plastic. Its main function is to ensure that the fluid inside the heat exchanger does not leak, while preventing external impurities from entering the heat exchanger and affecting its normal operation. After rough machining, the sealing strip needs to be ground before it can be used. Grinding the sealing strip can eliminate defects such as scratches and pits on the surface of the sealing strip, avoiding liquid leakage due to uneven surface. The ground surface can tightly fit the contact surface, significantly improving the sealing effect.

[0003] Currently, the main problems in the sealing strip grinding stage are as follows: high reliance on manual labor, low efficiency of manual grinding, poor consistency, and easy to cause uneven sealing surfaces; open grinding generates a large amount of rubber debris, which endangers the health of operators. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a rapid grinding device for plate heat exchanger sealing strips, which is highly automated and replaces manual grinding. During the grinding process, the generated debris can be adsorbed, reducing the impact on the surrounding environment and personnel.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a rapid grinding device for plate heat exchanger sealing strips, including a base, a fixed clamping plate, a movable clamping plate, a slide groove, a slider, a first electric telescopic rod, a column, a second electric telescopic rod, a track seat, an electric slide rail, a third electric telescopic rod, a grinding head, and a debris adsorption mechanism; the base is provided with a fixed clamping plate, and the front side of the fixed clamping plate is provided with a movable clamping plate, the fixed clamping plate and the movable clamping plate being arranged parallel to each other; the top surface of the base is provided with a slide groove corresponding to the lower part of the movable clamping plate, and the bottom of the movable clamping plate is connected to the slider. The slider is assembled in the groove; a first electric telescopic rod is installed on the top surface of the base, and the telescopic end of the first electric telescopic rod is connected to the front side of the movable clamping plate; a column is provided on the rear side of the fixed clamping plate, the bottom end of the column is connected to the base, the top end of the column is connected to the second electric telescopic rod, and the telescopic end of the second electric telescopic rod is connected to the track seat; an electric slide rail is installed at the bottom of the track seat, the slider of the electric slide rail is connected to the third electric telescopic rod, and the bottom end of the third electric telescopic rod is detachably connected to the grinding head; a set of debris adsorption mechanisms is provided on the top of both the fixed clamping plate and the movable clamping plate.

The feed inlet is located on one side of the body, and the air outlet is located on the other side. The fan generates air pressure, which draws the generated rubber debris into the body through the feed inlet, where it is stored in the filter bag. The gas is discharged from the air outlet.

[0007] A controller is installed on the base. The controller is electrically connected to the first electric telescopic rod, the second electric telescopic rod, the third electric telescopic rod, the electric slide rail, and the fan. The controller controls the working conditions of each component in a coordinated manner.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

Then, the position of the grinding head is adjusted by an electric telescopic rod to make it contact the top surface of the sealing strip. Under the action of an electric slide rail, it moves horizontally back and forth to complete the rapid grinding of the sealing strip. The whole process is highly automated and saves manpower.

[0010] A debris adsorption mechanism is installed above the clamping plate to adsorb the rubber debris generated during the grinding process, thereby reducing the impact on the surrounding environment and personnel. Attached Figure Description
