In this rubber product adhesion strength detection device, the temperature sensor transmits the temperature signal to the controller, and the controller controls the heating rod to stop heating, and brings the cold air inside the main body into the base for heating, thereby realizing the circulation of the air inside the main body and the base, and then can adjust the temperature environment inside the main body, thereby increasing the practicability of the device.

[0004] Although the above patent can realize the function of detecting the adhesion strength of rubber products, the current technology has incomplete considerations and has the following drawbacks: cutting the tape, but currently all adopt manual operations, with artificial positioning, scribing, and cutting, resulting in poor cutting quality, long working hours, and high labor intensity.

[0005] To solve one of the above problems, there is an urgent need for a single-edge cutter assembly for cutting conveyor belt sample strips. Content of the Utility Model

[0006] Based on the above deficiencies in the prior art, the technical problem to be solved by the utility model is: how to cooperate with the existing rocker-type cutting machine to cut the conveyor belt into sample strips for the alcohol blowtorch burning experiment and the adhesion strength test, and for this purpose, a single-edge cutter assembly for cutting conveyor belt sample strips is provided.

[0007] The single-edge cutter assembly for cutting sample strips of the conveyor belt of the utility model is characterized in that it includes a bearing plate, a cutting tool perpendicular to the bearing plate is arranged on the lower surface of the bearing plate, the bearing plate is consistent with the length direction of the cutting tool, and the cutting tool is detachably connected to the bearing plate through a fixing clamp, and a cutter assisting device is installed on one side of the bearing plate.

[0008] In cooperation with the existing rocker-type cutting machine, sample strips for alcohol blowtorch combustion experiments and bonding strength tests are cut out from the conveyor belt. The cutting steps are as follows: first, draw the position to be cut on the large conveyor belt, then place the conveyor belt to be cut on the workbench of the rocker-type cutting machine, and then align the cutting tool of this device with the marking line at the position to be cut. The cutter assisting device solves the problem that the cutting tool cannot stand alone. After turning on the rocker-type cutting machine, use the pressing mechanism on the rocker to apply pressure to the upper surface of the bearing plate, and the cutting tool cuts the conveyor belt. Finally, use the cutting tool to cut out sample strips for alcohol blowtorch combustion experiments and bonding strength tests on the large conveyor belt.

[0009] Preferably, the fixing clamp includes a front clamping plate fixedly connected to the bearing plate and a clamping and pushing member. The front clamping plate is arranged along the length direction of the bearing plate. The clamping and pushing member pushes the cutting tool to be close to the front clamping plate and then fits and abuts against each other, so that the clamping and pushing member and the front clamping plate cooperate to clamp the cutting tool.

[0010] The structure is simple and the processing is convenient. It can complete the rapid disassembly and assembly of the cutting tool, which is convenient for replacing the cutting tool.

[0011] Preferably, the front clamping plate is welded to the lower surface of the bearing plate, and there is a reinforcing rib between the bearing plate and the front clamping plate. The clamping and pushing member is arranged in multiple groups along the length direction of the bearing plate, including a rear vertical plate vertically connected to the bearing plate. A through hole A for the tightening bolt to pass through is opened on the rear vertical plate, and a connecting nut coaxial with the through hole A is opened on the rear vertical plate.
