[0002] Adhesive products are common daily necessities in life. Adhesive products such as tapes are used very frequently. Cutting molds are required for cutting during the production of adhesive products.

[0003] Traditional cutting equipment uses a punch press to cut products with a harder texture, but the traditional punch press is not equipped with a traction mechanism, and the product needs to be placed manually for punching, which results in low manual operation efficiency.

[0004] Therefore, how to provide a continuous traction mechanism for a punching machine tool to solve the problems existing in the prior art is of great significance to its application. Utility Model Content

[0005] In view of this, the purpose of the present application is to provide a continuous traction mechanism for a punching machine to solve the problem that a punch press is used in traditional cutting equipment to cut products with a harder texture. However, the traditional punch press is not equipped with a traction mechanism, and the product needs to be placed manually for punching, resulting in low efficiency of manual operation.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A continuous traction mechanism of a punching machine tool comprises a first side plate, wherein the number of the first side plates is two, the two first side plates are fixedly connected by a first connecting rod and a fourth connecting rod, both ends of the first connecting rod are rotatably connected with a rotating plate, a pressure roller is rotatably connected between the two rotating plates, a driving roller is rotatably connected between the two first side plates, both ends of the driving roller are provided with a driving gear, both ends of the pressure roller are provided with a transmission gear, the transmission gear and the driving gear are meshingly connected, one end of the fourth connecting rod is rotatably connected with a rotating rod, a groove ring is installed at the end of the rotating rod, a slot is provided on one side of the rotating plate, and the other end of the rotating rod is fitted with the bottom end of the slot.

[0008] Preferably, a fixing block is fixedly connected to the inner side of the first side plate, a fixing screw is connected to the top of the fixing block, a fixing nut is installed on the top of the fixing screw, and the bottom end of the fixing nut is elastically connected to the top of the rotating plate via a spring.

[0009] Preferably, a motor is installed on the outer side of the first side plate, and the output end of the motor is drivingly connected to the driving roller.

[0010] Preferably, the two first side plates are fixedly connected to the second side plates, and the two second side plates are fixedly connected via a second connecting rod and a third connecting rod.

[0011] Preferably, a sliding rod is fixedly connected between the two second side plates, and the top end of the sliding rod is slidably connected to a limiting block.

[0012] Preferably, a limiting screw rod passes through the interior of the limiting block, and a limiting nut is threadedly connected to the bottom end of the limiting screw rod, and the limiting nut is located below the sliding rod.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model realizes traction of the material strip through the driving roller and the pressure roller. When in use, the material strip is passed between the driving roller and the pressure roller, and then the motor is started. At this time, the motor drives the driving roller to rotate, and the driving roller drives the pressure roller to rotate through the driving gear and the transmission gear, thereby realizing traction of the material strip and achieving continuous and efficient punching.

[0015] 2. The utility model can temporarily loosen the material strip during punching and cutting, and install a pressure rod on the punch head of the punch press. When the pressure rod moves downward, it presses the rotating wheel downward. At this time, the other end of the rotating rod lifts the rotating plate, so that the pressure roller is lifted to a certain height, thereby losing the traction force on the material strip, thereby avoiding deformation of the material strip, thereby providing a better punching effect.

[0016] 3. The two limit blocks in the utility model can adjust the spacing, so as to limit the material strips of different widths.

[0029] A motor 1 is installed on the outer side of the first side plate 2. The output end of the motor 1 is transmission-connected to the driving roller 3. The motor 1 drives the driving roller 3 to rotate, thereby driving the material belt to be pulled.
