In the embodiment of the present application, a lever structure may be formed by the transmission rod 322 to transmit driving force by the transmission rod 322, and the rotation force of the transmission shaft 321 may be converted into the reciprocation force of the mounting base 210 by the protrusion 321a of the transmission shaft 321 being provided on the transmission shaft 321 and the protrusion 321a of the transmission shaft 321 being engaged with the transmission rod 322. In this way, the transmission mechanism 320 not only realizes the power transmission between the driving mechanism 310 and the material pressing mechanism 200, but also can change the transmission direction of the force, thereby facilitating the structural layout of the whole device.

In a specific application, by providing the rotating portion 322c between the first transmitting portion 322a and the second transmitting portion 332b of the transmission lever 322, the rotating portion 322c is rotatably connected to the frame 100, so that a lever structure is formed by the first transmitting portion 322a, the second transmitting portion 332b and the rotating portion 322c, and the first transmitting portion 322a and the second transmitting portion 332b of the transmission lever 322 can rotate around the rotating portion 322c, thereby achieving transmission of forces at both ends of the transmission lever 322.

When the transmission shaft 321 drives the protrusion 321a to approach the second transmission portion 332b of the transmission rod 322, the protrusion 321a pushes the second transmission portion 332b to rotate around the rotation portion 322c, and based on leverage, the power of the driving mechanism 310 can be transmitted to the first transmission portion 322a, and then the first transmission portion 322a pushes the mounting seat 210 to move towards the pressing plane 101, so that the welding strip pressure head 220 performs the flattening operation on the welding strip 102.

In some embodiments, the transmission mechanism 320 may include a plurality of transmission rods 322, where a first transmission portion 322a of each transmission rod 322 abuts against the mounting base 210, a second transmission portion 332b abuts against the transmission shaft 321, a rotation portion 322c is rotatably connected with the frame 100, and a protrusion 321a is disposed on the transmission shaft 321 corresponding to a position of the second transmission portion 332b of each transmission rod 322.

In the embodiment of the present application, by arranging the plurality of transmission rods 322, the plurality of transmission rods 322 may be arranged at intervals along the second direction Y, and the driving stability of the pressing mechanism 200 may be improved by using the force transmission effect of the plurality of transmission rods 322.

It should be noted that the number of the transmission rods 322 in the transmission mechanism 320 may be one or multiple, and the specific number and the setting positions of the transmission rods 322 may be set according to actual needs, which is not limited herein.

In some embodiments, the distance between the second transmission portion 332b and the rotating portion 322c is greater than the distance between the first transmission portion 322a and the rotating portion 322c, and based on the lever principle, the driving action on the pressing mechanism 200 can be achieved through a smaller driving force, which is helpful for achieving the amplifying action of the driving force, saving the energy consumption of the driving mechanism 310, and reducing the production cost.

The distance between the second transmission portion 332b and the rotation portion 322c refers to the distance between the contact point between the second transmission portion 332b and the transmission shaft 321 and the rotation axis of the frame 100, and the distance between the first transmission portion 322a and the rotation portion 322c refers to the distance between the contact point between the first transmission portion 322a and the mounting base 210 and the rotation axis of the rotation portion 322c and the rotation axis of the frame 100.

When the second transmission portion 332b is in surface contact and line contact with the transmission shaft 321, the contact point is the center point of the contact surface or the contact line, and the determination method of the contact point of the first transmission portion 322a and the mounting seat 210 is the same.

In some embodiments, the angle between the center line of the second transmission portion 332b and the rotation portion 322c and the center line of the first transmission portion 322a and the rotation portion 322c is less than 90 °. Preferably, the included angle is 75 ° to 85 °, and illustratively, the included angle may be set as: any angle of 75 °, 77 °, 80 °, 82 °, 85 °, etc., and a range between any two angles.

In particular, when the transmission shaft 321 rotates to drive the protrusion 321a to approach the second transmission portion 332b of the transmission rod 322, the protrusion 321a pushes the second transmission portion 332b to rotate around the rotation portion 332c, and under the leverage, the first transmission portion 322a presses the bearing shaft 323 and pushes the bearing shaft 323 to drive the mounting base 210 to move. Because the pressure-bearing rotating shaft 323 is rotatably connected to the mounting base 210, when the pressure-bearing rotating shaft 323 receives the thrust of the first transmission portion 322a, the pressure-bearing rotating shaft 323 moves linearly and rotates, so that friction between the pressure-bearing rotating shaft 323 and the first transmission portion 322a is reduced.

Illustratively, the bearing rotating shaft 323 may be provided as a cylindrical shaft, and the arc surface is a cylindrical surface of the cylindrical shaft. Of course, the bearing shaft 323 may be configured in other shapes, and may be configured according to actual needs, which is not limited herein.

Specifically, the first gear 324 is rotatably connected to the output end of the driving mechanism 310, the second gear 325 is connected to the driving shaft 321, and the driving mechanism 310 drives the first gear 324 to rotate, and the first gear 324 drives the second gear 325 to rotate, so as to drive the driving shaft 321 to rotate, so as to change the relative position between the protrusion 321a and the driving rod 322.

Wherein, the number of teeth of the first gear 324 may be smaller than the number of teeth of the second gear 325, and after the first gear 324 is meshed with the second gear 325, the rotation speed output by the driving mechanism 310 may be reduced, and the torque output by the driving mechanism 310 may be further increased, so as to meet the flattening requirement of the butt welding belt 102.
