Description

Technical Field

[0001] The utility model relates to the technical field of cardboard processing, in particular to a puncher for packaging cardboard. Background Art

[0002] Packaging cardboard is a general term for cardboard used for packaging, including white cardboard, yellow cardboard, kraft paper, corrugated cardboard, etc. It is generally required to have strong durability and good bending properties. Packaging cardboard is generally made of wood, straw, etc., pulped by different methods, and made on a cardboard machine.

[0003] A punching device is disclosed in a patent publication (publication number CN220262151U). When punching holes in a cardboard during production, a hydraulic rod and a movable plate are provided. The hydraulic rod drives the movable plate downward to approach the cardboard, thereby limiting the position of the cardboard during the punching process. However, this method only limits the position of the entire cardboard during use, and cannot effectively and firmly fix the area where the holes are punched. Therefore, the area where the limit is fixed is preferably the area where the holes are being punched, so that the fixing effect will be better.

[0004] Therefore, in view of the above-mentioned problems, a puncher for packaging paperboard is now proposed, which can fix the area being punched during the punching process. Utility Model Content

[0005] The utility model aims to provide a puncher for packaging paperboard, so as to solve the problem that the above-mentioned background technology fixes the whole paperboard but cannot solve the problem that the paperboard in the punching area is unstable.

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

[0007] A puncher for packaging cardboard includes a support base for support and a punching device arranged on the support base for punching packaging cardboard, wherein the punching device includes a fixed base, a moving mechanism is fixedly installed on the top of the fixed base, a puncher is arranged on the moving mechanism, and the puncher can move on the moving mechanism to realize punching at different positions of the cardboard.

[0008] As a further solution of the utility model: wherein, the moving mechanism includes a fixed frame arranged on a fixed seat, a threaded rod is rotatably connected to the interior of the fixed frame, a moving block is meshingly connected to the threaded rod, a retractable support plate is fixedly installed on one side of the moving block, the support plate extends outward from the interior of the fixed frame, and when the puncher is installed on the support plate, a power mechanism connected to the threaded rod is fixedly installed on one side of the fixed frame.

[0009] As a further solution of the utility model: wherein, positioning plates are fixedly installed on both sides of the fixing seat, and a group of guide rollers are rotatably connected between two positioning plates relative to each other.

[0010] As a further solution of the utility model: wherein, the two guide rollers are designed to be one above and one below.

[0011] As a further solution of the utility model: wherein, the puncher includes a top plate threadedly connected to the support plate, the bottom of the top plate is connected to the bottom plate through a telescopic member, guide rods are provided on both sides of the telescopic member, and a clamping block is fixedly installed on the bottom of the bottom plate.

[0012] As a further solution of the utility model: wherein, the guide rod includes a guide cylinder and a movable rod, the movable rod can move up and down inside the guide cylinder, and a return spring is arranged between the movable rod and the guide cylinder, the bottom of the guide cylinder is connected to the bottom plate, and the top of the guide rod is connected to the top plate.

[0013] As a further solution of the utility model: wherein, the number of the clamping blocks is four and they are symmetrically distributed at both ends of the punching machine end.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The puncher for packaging cardboard is provided with an up-and-down moving mechanism on the support plate, and the up-and-down moving mechanism is used to control the punching end of the puncher to approach or move away from the cardboard, so that the punching effect can be achieved. In the process of the puncher moving up and down, the top plate will be driven to move up and down synchronously. At this time, when the punching end contacts the cardboard, the pressing block will also contact the cardboard. When the end punches a hole on the cardboard and moves down, the pressing block will also move down accordingly, and the pressing block moves together with the puncher, so that the pressing effect on the cardboard during the punching process can be achieved.

[0016] In addition, there are four pressing blocks, which are evenly and symmetrically distributed at both ends of the punching machine head. This distribution form can better effectively fix the area where the cardboard is punched. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] See also Figure 1 , which is a schematic diagram of the overall structure of a puncher for packaging cardboard, the device includes a support base 10 for supporting, and a punching device 20 arranged on the support base 10 for punching packaging cardboard, the punching device 20 includes a fixed base 21, a moving mechanism 22 is fixedly installed on the top of the fixed base 21, a puncher 23 is arranged on the moving mechanism 22, and the puncher 23 can move on the moving mechanism 22 to realize punching at different positions of the cardboard.

[0023] Specifically, the mobile mechanism 22 includes a fixed frame 221 arranged on a fixed seat 21, a threaded rod 222 is rotatably connected inside the fixed frame 221, a moving block 223 is meshedly connected on the threaded rod 222, a retractable support plate 224 is fixedly installed on one side of the moving block 223, the support plate 224 extends outward from the inside of the fixed frame 221, and the punch 23 is installed on the support plate 224, a power mechanism connected to the threaded rod 222 is fixedly installed on one side of the fixed frame 221, and the power mechanism can be a motor, and the output shaft of the motor is fixedly connected to the threaded rod 222. In this embodiment, the threaded rod 222 is driven to rotate by the power mechanism, and the threaded rod 222 can drive the moving block 223 to move inside the fixed frame 221 during the rotation process, and when the threaded rod 222 is reversed, the moving block 223 can be driven to move back. Thereby controlling the movement of the support plate 224 fixedly connected to the moving block 223.

[0024] Further, such as Figure 2 and Figure 3 As shown, positioning plates 211 are fixedly installed on both sides of the fixing seat 21, and a group of guide rollers 212 are rotatably connected between the two positioning plates 211, and the two guide rollers 212 are designed to be one up and one down. A driving wheel is rotatably connected to the side of the fixing frame 221 away from the power mechanism, and the driving wheel drives the guide rollers 212 to rotate through the sprocket design. In this embodiment, by setting the guide rollers 212 in the direction of the cardboard entering, the distribution of the cardboard on the guide rollers 212 is as shown in FIG. Figure 3As shown, the guide roller 212 can press the paperboard, so that when the paperboard comes out of the guide roller 212, the guide roller 212 can initially give the paperboard a limiting force under the pressure of the guide roller 212, thereby avoiding the problem of the paperboard slipping when the drill bit of the punch 23 starts to contact the paperboard before punching.

[0025] Furthermore, the puncher 23 includes a top plate 30 threadedly connected to the support plate 224, the bottom of the top plate 30 is connected to the bottom plate 32 through a telescopic member 31, guide rods 33 are arranged on both sides of the telescopic member 31, the guide rods 33 include a guide cylinder 331 and a movable rod 332, the movable rod 332 can move up and down inside the guide cylinder 331, and a return spring 333 is arranged between the movable rod 332 and the guide cylinder 331, the bottom of the guide cylinder 331 is connected to the bottom plate 32, the top of the movable rod 332 is connected to the top plate 30, and a pressing block 34 is fixedly installed at the bottom of the bottom plate 32.
