[0002] With the rapid development of my country's waterproofing membrane industry, the performance and reliability requirements for felt roll machines are becoming increasingly higher. Traditional felt roll machines have some shortcomings in the design of the cutting frame. The belt drive mechanism is installed in the cutting box, which makes it impossible to conduct spot inspections of the belt ends and bearings during daily production. This can easily cause sudden production interruptions and downtime, often requiring downtime for inspection. Maintenance is difficult and time-consuming, seriously affecting production efficiency. In addition, the cutting frame of traditional felt roll machines cannot adjust the tension of the belt. After long-term use and high-load working conditions, the belt joints will be stretched and deformed, and the entire belt needs to be replaced, which is not only troublesome to operate but also increases the cost of use.

[0022] The belt transmission mechanism 2 includes a motor 201, a belt 202, a driving shaft 203, a driven shaft 204, a driving pulley 205, and a driven pulley 206. The driving shaft 203 is mounted on the synchronous wheel mounting seat 8 through a bearing. The motor 201 is mounted on the side wall of the synchronous wheel mounting seat 8. The motor 201 is connected to the driving shaft 203 through transmission. The driving pulley 205 is mounted on the driving shaft 203. The driven shaft 204 is mounted on the U-shaped adjustment seat 701 through a bearing. The driven pulley 206 is mounted on the driven shaft 204. The belt 202 is wound around the driving pulley 20 5 and the driven pulley 206, and the end of the belt 202 is connected to the end face of the L-shaped connecting block 10 by a bolt, and the other end face of the L-shaped connecting block 10 is connected to the movable base 5 by a screw; the motor 201 drives the driving shaft 203 to rotate, so that the driving pulley 205 rotates, and the rotation of the driving pulley 205 drives the belt 202 to move, and the belt 202 drives the driven shaft 204 to rotate through the engagement with the driven pulley 206.

Two sets of waist-shaped guide grooves 7011 are provided on the left and right side walls of the U-shaped adjustment seat 701. The guide screw 702 passes through the waist-shaped guide groove 7011 and is threadedly connected to the side wall of the support beam 1, so that the U-shaped adjustment seat 701 can slide along the guide screw 702, thereby achieving the tensioning or relaxation of the belt 202. The U-shaped adjustment seat 701 is slidably installed at the end of the support beam 1 through the guide screw 702. Positioning blocks 705 are installed on the left and right side walls of the support beam 1. A rotatable screw 703 is installed on the positioning block 705. The screw 703 passes through the U-shaped adjustment seat 701 and is threadedly connected to it, and the end of the screw 703 is installed It is equipped with a knob 704; when the belt 202 becomes loose, the operator rotates the knob 704 to rotate the screw 703, pushing the U-shaped adjustment seat 701 to move along the guide screw 702, and then adjusting the tension of the belt 202 to ensure that the belt 202 maintains appropriate tension during the transmission process and avoids sudden interruptions in the production process; when the end of the belt 202 is torn, the operator rotates the knob 704 in the opposite direction to rotate the screw 703 in the opposite direction, pushing the U-shaped adjustment seat 701 to move in the opposite direction, so that the belt 202 is loose and easy to remove, and then, the damaged part of the removed belt 202 is cut off, the intact part is reconnected and tensioned again, realizing secondary utilization, which not only reduces production costs but also reduces material waste.

[0024] The support beam 1 is made of I-shaped aviation aluminum material, and the belt 202 is located in the I-shaped groove of the support beam 1; the design of the I-shaped groove makes the installation and replacement of the belt more convenient, reduces the time and difficulty of maintenance work, and has a compact structure.

[0025] The cutter 6 is provided with concave arc-shaped blades 601 on both side edges; the arc-shaped blades can make it easier for the cutter 6 to cut into the material when it contacts the material, thereby improving the cutting efficiency and effect. Compared with the straight blade, the arc-shaped blade can reduce the friction resistance with the material to a certain extent during the cutting process, making the cutting process smoother, helping to make the cutting edge neater and smoother, and reducing the occurrence of undesirable conditions such as burrs.
