Description

Technical Field

[0001] The utility model relates to punching and cutting equipment, in particular to a linkage type tension-free feeding and punching and cutting mechanism. Background Art

[0002] Punching mechanisms are used to punch various types of materials. One type of punching mechanism is used to punch various types of unwound substrates. Its working principle is to continuously pull the material to the punching assembly through the rear traction assembly for punching. The above structure has the following drawbacks: in actual use, since the substrate will inevitably be subjected to a certain pulling and stretching force during the traction process, for some materials with poor tensile strength, when being pulled and stretched to the punching assembly, they will already have undergone a certain degree of deformation and stretching due to excessive tension. This will cause the punching position to change, affecting the punching quality. Utility Model Content

[0003] In view of the shortcomings of the background technology, the technical problem to be solved by the present invention is to provide a linkage type tension-free feeding and punching mechanism for solving the above problems.

[0004] To this end, the present invention is implemented by adopting the following scheme:

[0005] A linkage-type tension-free feeding and punching mechanism is characterized in that it includes a front traction roller group and a rear traction roller group, a positioning detection component is provided near the feed end of the front traction roller group, and a punching component is provided between the front and rear traction roller groups. The positioning detection component will feedback information to a controller, and the controller can control the actions of the front and rear traction roller groups, and the traction speeds of the front traction roller group and the rear traction roller group are kept consistent, so that the material will not be affected by the traction tension when being transported between the front and rear traction roller groups.

[0006] The positioning detection component is a color mark sensor.

[0007] The front traction roller group includes a first lower traction roller, a first upper traction roller is pressed above the first lower traction roller, and the first lower traction roller is connected to the first drive shaft. The rear traction roller group includes a second lower traction roller, a second upper traction roller is pressed above the second lower traction roller, and the second lower traction roller is connected to the second drive shaft. The first and second drive shafts are both connected to the first motor.

[0008] The punching assembly includes a punching platform. A lifting frame is provided above the punching platform. The lifting frame is connected to the lifting drive assembly. A punching seat is installed on the lifting frame. A punching knife is provided on the punching seat.

[0009] The lifting drive assembly includes a second motor, which is connected to a transmission shaft through a synchronous belt transmission group. The transmission shaft is eccentrically connected to a rotating wheel. A transmission sleeve is provided on the outer shell of the rotating wheel. A transmission arm is extended from the transmission sleeve. One end of the transmission arm is hinged to the crossbeam on the lifting frame.

[0010] The above technical solution is a linkage type tension-free feeding and punching mechanism, which arranges the punching component between the front and rear traction roller groups, and keeps the traction speed of the front and rear roller groups consistent. The material located between the front and rear traction roller groups is pulled at the same speed in the front and back to achieve front-to-back linkage transportation, which will prevent the material in this part from being stretched, ensuring that the material will not be deformed when it is sent to the punching component after completing the positioning detection, thereby ensuring the accuracy of the punching position. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The utility model has the following drawings:

[0012] Figure 1 It is a structural diagram of the present utility model. DETAILED DESCRIPTION

[0013] As shown in the figure, the utility model discloses a linkage tension-free feeding and punching mechanism, which includes a front traction roller group and a rear traction roller group. A positioning detection component is provided near the feed end of the front traction roller group. In this embodiment, the positioning detection component is a color code sensor 1. Of course, it can also be other sensing devices such as a high-speed camera. A punching component is provided between the front and rear traction roller groups. The positioning detection component will feedback information to the controller, and the controller can control the action of the front and rear traction roller groups, and the traction speeds of the front and rear traction roller groups are kept consistent, so that the material will not be affected by the traction tension when being transported between the front and rear traction roller groups.

[0014] Specifically, the front traction roller assembly includes a first lower traction roller 2, with a first upper traction roller 3 pressing against the top of the first lower traction roller 2 and connected to a first drive shaft. The rear traction roller assembly includes a second lower traction roller 8, with a second upper traction roller 7 pressing against the top of the second lower traction roller 8 and connected to a second drive shaft. Both the first and second drive shafts are in transmission connection with a first motor. By controlling the first motor to drive the first and second drive shafts to rotate, the first and second lower traction rollers can be driven to rotate, and cooperate with the first and second upper traction rollers to perform traction.

[0015] Specifically, the punching assembly includes a punching platform 9, and a lifting frame 4 is provided above the punching platform 9. The lifting frame 4 is raised and lowered accordingly. The lifting frame 4 is connected to the lifting drive assembly. A punching seat 5 is installed on the lifting frame 4, and a punching knife 6 is provided on the punching seat 5. The lifting drive assembly includes a second motor 10. The second motor 10 is connected to the transmission shaft through a synchronous belt transmission group 11. The transmission shaft is eccentrically connected to the rotating wheel 12. The rotating wheel 12 is provided with a transmission sleeve 13. A transmission arm 14 is extended from the transmission sleeve 13. One end of the transmission arm 14 is hinged to the crossbeam 15 on the lifting frame 4. By controlling the second motor 10 to drive the transmission shaft to rotate, the rotating wheel 12 is driven to rotate. The rotating wheel 12 will drive the transmission sleeve 13 to move, and the lifting frame 4 is driven to rise and fall through the transmission arm 14, thereby driving the punching knife 6 to rise and fall and cooperate with the punching platform 9 to perform punching.

[0016] The working principle of the present invention is as follows: the material is first pulled by the front traction roller group and passes through the color mark sensor 1. The color mark sensor 1 detects the color mark on the material and feeds back the information to the controller. The controller controls the front and rear traction roller groups to move synchronously, driving the material to be pulled a suitable distance, so that the position to be punched of the material moves to the punching component, and the punching component acts to punch the material.

[0017] The structure of the present invention arranges the punching assembly between the front and rear traction roller groups, and the traction speeds of the front and rear roller groups are kept consistent. The materials located between the front and rear traction roller groups are pulled at the same speed in the front and rear to achieve front-to-back linkage transportation, which will prevent the materials in this area from being stretched, ensuring that the materials will not be deformed during the process of being sent to the punching assembly after completing the positioning detection, thereby ensuring the accuracy of the punching position.
