[0031] Combination Figure 3 and Figure 4 As shown, the transmission assembly includes a motor 2, a first driving wheel 3, a second driving wheel 5, a first driven wheel 4, a second driven wheel 6 and a third driven wheel 7.

[0034] like Fig.10As shown, the cutting assembly includes a conveying part 20, a cutting part 21, a scale sensor and a controller, and the conveying part 20 is adjacent to the first forming roller 11 and the second forming roller 12. The conveying part 20 includes a U-shaped groove 2002, which is fixedly connected to the top of the frame 1, and a plurality of conveying rollers 2001 are connected to the U-shaped groove 2002 along the lateral rotation. The cutting part 21 includes a gantry 2101, a cutter 2103, a support and a plurality of telescopic cylinders 2102, and the support is fixed in the gantry 2101 and is in the same plane as the plurality of conveying rollers 2001 in the U-shaped groove 2002. The upper part of each telescopic cylinder 2102 is fixedly connected to the top of the gantry 2101, and the lower end is fixedly connected to the cutter 2103. The scale sensor is fixed on the gantry 2101, and the controller is respectively connected to the scale sensor and each telescopic cylinder 2102. The controller controls the telescopic cylinder 2102 and the cutter 2103 to cut the material to a fixed length according to the material length data detected by the scale sensor.

[0035] When in use, the raw materials of the honeycomb sealing tapes on the market are all in the form of coils for the convenience of transportation and saving placement space. In addition, during the process of curling, rolling and heat treatment, the raw materials will have various wave-shaped defects in the rolled plates due to the uneven longitudinal extension of the plates along the width direction. The first straightening part, the second straightening part and the third straightening part cooperate to achieve the straightness of the raw materials, reduce the residual stress, and make the residual stress after straightening uniformly distributed. The first straightening part, the second straightening part and the third straightening part are adapted to flatten the raw materials, and the raw materials are placed between the first straightening part, the second straightening part and the third straightening part. The user can adjust the spacing between the third straightening wheel 25 and the first straightening wheel 23 and the second straightening wheel 24 through the nuts on each bracket 19, and adjust the spacing between the fourth straightening wheel 26 and the fifth straightening wheel 27 to flatten the raw materials. In the present invention, the straightening assembly applies positive and negative deflections to the raw materials through each straightening roller, so that the raw materials form different amounts of depression along the plate width direction, resulting in different degrees of tensile deformation. The user can move the third straightening wheel 25 and the fifth straightening wheel 27 up and down to form different amounts of reduction, among which the reduction amount in the middle of the raw material is the largest and the bending moment it is subjected to is the largest. Similarly, the bending moment subjected to the edge is the smallest, and the longitudinal fibers produce gradually increasing tensile deformation from the edge to the middle.

[0036] The first forming roller 11 and the second forming roller 12 are adapted to mesh with each other to perform honeycomb forming processing on the raw material by extrusion. Under the action of the first forming roller 11 and the second forming roller 12, the extrusion force and friction force on the metal sheet are evenly distributed, which can effectively avoid the excessive extrusion or deformation of the raw material locally, so that it forms a uniform honeycomb structure. In addition, the extrusion forming operation is flexible, and the user can adjust the spacing between the first forming roller 11 and the second forming roller 12 according to the thickness of the raw material plate. The user turns the handle 14 to drive the second screw 22 to rotate using the worm gear 13 structure, thereby driving the first spline shaft 9 and the second spline shaft 10 to move toward or away from each other in the up and down direction, and then adjust the spacing between the first forming roller 11 and the second forming roller 12. The user can also replace the first forming roller 11 and the second forming roller 12 of different specifications according to the size requirements of the product. The present invention can produce diversified products with different shapes and specifications on one device. After the raw material is processed and formed, it is transported to the cutting part through the conveying roller 2001 in the conveying part 20. The scale sensor detects the length of the formed raw material in real time and transmits the data to the controller. The user can pre-set the cutting length through the controller. When the controller detects that the length of the formed raw material passing through reaches the preset cutting length according to the scale sensor, the cutting operation is performed according to the fixed length. The controller automatically controls the telescopic cylinder 2102 to extend, driving the cutter 2103 to move downward, and the cutter 2103 cooperates with the support table to achieve cutting. After cutting, each telescopic cylinder 2102 automatically resets.

[0037] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
