Description

Technical Field

[0001] This utility model relates to punching equipment, specifically to a highly stable punching device. Background Technology

[0002] The punching device is mainly used to punch and shape materials. One type of punching device continuously punches the unwound material. During the unwinding and traction process, due to the difference between the traction speed and the punching speed, it is easy for too much or too little material to be traction. At this time, it is necessary to set up a material storage component to pre-store the material, so that when the material is too little, the material is released to replenish it, and when the material is too much, it is pre-stored in the material storage component. The traditional material storage component uses a movable material storage roller group structure. The material passes around the material storage roller, and the release or storage of the material is achieved by controlling the movement of the material storage roller. The drawbacks of this structure are: the overall material storage structure is complex, the installation space required is large, and the material needs to be kept in a tensioned state for the material storage roller to move. It is not very suitable for some hard materials. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a highly stable punching device for solving the above-mentioned problems.

[0004] Therefore, this utility model is implemented using the following solution:

[0005] A high-stability punching device includes an unwinding frame and a traction roller group on one side of the unwinding frame. The device is characterized by: a first feed plate at the discharge end of the traction roller group; an upper guide plate above the first feed plate; material bends upwards after passing through the first feed plate and is conveyed backwards along the upper guide plate; a second feed plate at the discharge end of the upper guide plate; a guide plate group at the discharge end of the second feed plate; and a punching assembly at the discharge end of the guide plate group.

[0006] A sensor is provided at the end of the guide plate, which can feed back information to the controller, which is used to control the movement of the traction roller group.

[0007] A set of inverted rollers is provided at the discharge end of the unwinding frame, and one side of the inverted rollers is connected to the traction rollers.

[0008] The punching assembly includes a front punching cutter plate with a punching cutter groove, a rear punching cutter plate with a punching cutter that mates with the punching cutter groove on one side of the front punching cutter plate, and the rear punching cutter plate is connected to a motion drive assembly.

[0009] The moving drive assembly includes a first motor, which is connected to a rotating wheel. The rotating wheel is eccentrically hinged to one end of a transmission arm, and the other end of the transmission arm is hinged to a rear punch cutter plate. A guide assembly is provided corresponding to the rear punch cutter plate.

[0010] It also includes a transfer arm, which is hinged to the frame. One end of the transfer arm is hinged to the piston rod of the first cylinder, and the other end of the transfer arm is provided with a groove for placing the unwinding roller.

[0011] Anti-tilting pressure rollers are arranged above the discharge end of the second feed plate.

[0012] A locking gear is provided on the unwinding roller, and a locking insert is also included. One end of the locking insert is connected to the piston rod of the second cylinder. A spring is provided between the locking insert and the cylinder body of the second cylinder. The locking insert can be inserted into the locking gear.

[0013] It also includes a support plate hinged to the unwinding frame, the support plate being hinged to the piston rod of the third cylinder, the support plate being able to contact the unwinding roller and provide rotational support for the unwinding roller.

[0014] The beneficial effects of the above technical solution are: 1. The use of the first feed plate and the upper guide plate to enclose the space realizes the suspended storage of materials, eliminating the need to set up a movable winding roller structure, making its structure simpler and easier to assemble, especially suitable for storing hard materials; 2. By setting up locking gears and locking inserts, the automatic and rapid locking of the unwinding roller can be realized. Attached Figure Description

[0021] As shown in the figure, the present invention discloses a high-stability punching device, including an unwinding frame 3, a traction roller group 14 is provided on one side of the unwinding frame 3, a first feed plate 15 is provided at the discharge end of the traction roller group 14, an upper guide plate 17 is provided above the first feed plate 15, the material 16 bends upward after passing through the first feed plate 15 and is conveyed backward along the upper guide plate 17, a second feed plate 20 is provided at the discharge end of the upper guide plate 17, a guide plate group 21 is provided at the discharge end of the second feed plate 20, and a punching component is provided at the discharge end of the guide plate group 21.

[0022] Furthermore, a sensor 18 is provided at the end of the guide plate 17. The sensor 18 can feed back information to the controller, which is used to control the movement of the traction roller group 14. With the above structure, when the sensor 18 senses the unwinding material, it indicates that the material is about to reach the upper limit. At this time, the sensor 18 will feed back information and control the traction roller group 14 to stop or slow down the traction speed.

[0023] Furthermore, a reverse-curve roller group 8 is provided at the discharge end of the unwinding frame 3, and one side of the reverse-curve roller group 8 is connected to the traction roller group 14. With the above structure, the unwound material can be reverse-curved during unwinding, so that the material can be kept in a relatively flat state for backward traction and conveying.

[0024] Furthermore, the punching assembly includes a front punching blade 13 with a punching groove. A rear punching blade 12 is located on one side of the front punching blade 13, and a punching blade that mates with the punching groove is located on the rear punching blade 12. The rear punching blade 12 is connected to a moving drive assembly. Specifically, the moving drive assembly includes a first motor 9, which is connected to a rotating wheel 10. The rotating wheel 10 is eccentrically hinged to one end of a transmission arm 11, and the other end of the transmission arm 11 is hinged to the rear punching blade 12. A guide assembly is located on the rear punching blade 12. With this structure, by controlling the movement of the rear punching blade 12, the punching blade can be driven to compress the material delivered there and mate with the punching groove to achieve punching of the material.

[0025] Furthermore, it also includes a transfer arm 2, which is hinged to the frame. One end of the transfer arm 2 is hinged to the piston rod of the first cylinder 1, and the other end of the transfer arm 2 is provided with a groove 4 for placing the unwinding roller 5. With the above structure, it is convenient to realize the up and down transfer of the unwinding roller 5.

[0026] Furthermore, anti-tilting pressure rollers 19 are arranged above the discharge end of the second feed plate 20. This structure ensures that the material can be smoothly conveyed downwards in a bending motion, making the material transfer more stable.

[0027] Furthermore, a locking gear 22 is provided on the unwinding roller 5, and a locking insert 23 is also included. One end of the locking insert 23 is connected to the piston rod of the second cylinder 25, and the locking insert 23 can be inserted into the locking gear 22. With the above structure, the locking and positioning of the unwinding roller can be achieved through the mutual cooperation between the locking insert 23 and the locking gear 22. A spring 24 is also tightly pressed between the locking insert 23 and the cylinder body of the second cylinder 25. With the above technical solution, when the power is normally on, the second cylinder 25 will drive the locking insert 23 to move upward and separate from the locking gear 22 and squeeze the spring 24. When a sudden power failure occurs, the second cylinder 25 loses its pneumatic force. At this time, the spring 24 will squeeze the locking insert 23 to descend rapidly and insert into the locking gear 22, thereby achieving rapid locking and braking of the unwinding roller 5, preventing the roll from continuously rotating due to inertia when the power is lost, which would cause the paper film to spill all over the ground.

[0028] Furthermore, it also includes a support plate 6 hinged to the unwinding frame 3. The support plate 6 is hinged to the piston rod of the third cylinder 7. The support plate 6 can contact the unwinding roller 5 and provide rotational support for the unwinding roller 5. With the above structure, after the unwinding roller 5 is placed in position on the unwinding frame, the support plate 6 can be controlled to swing and contact the unwinding roller 5, thereby achieving rotational support for the unwinding roller 5 and ensuring the stability of its position during the unwinding process.

[0029] The working principle of this utility model is as follows: The material is first unwound by the unwinding roller 5 and then bent by the reversing roller group 8. It is then pulled to the first feed plate 15, bent upwards and conveyed backwards along the upper guide plate 17. The first feed plate 15 and the upper guide plate 17 enclose a storage space, so that the material can be pre-stored there or replenished if the material is insufficient in subsequent steps. After that, it passes through the second feed plate 20 and is conveyed downwards to the guide plate group 21 until the material is sent to the punching assembly for punching processing to obtain the material of the required shape.
