A high-efficiency fixed-length cardboard slitting machine

Abstract

This utility model relates to the field of cardboard slitting technology and discloses a high-efficiency fixed-length cardboard slitting machine, including two worktables, a drive motor, a conveyor belt, a first electric telescopic rod, and a cutting blade assembly. By controlling the second electric telescopic rod to move the mounting base in the opposite direction, the cardboard can be pushed out from under the height limit frame and into the conveyor belt. This solves the problem of low efficiency in existing slitting machines, which require a full round trip to push out a single cardboard sheet, greatly increasing the paper cutting efficiency of the slitting machine. By controlling the rotation of the positioning bolts, the worktable can be supported and moved on the guide rail. When the worktable moves, the slide will move forward or backward relative to the paper support frame, thereby extending and retracting the paper support frame. In use, after the cardboard is stacked between the two height limit frames, the positioning bolts are further controlled to make the height limit frames clamp the cardboard, thereby expanding the capacity of the paper support frame and ensuring that cardboard of different sizes can be stacked between the two height limit frames.

Description

Technical Field

[0001] This utility model relates to the field of cardboard slitting technology, specifically to a high-efficiency fixed-length cardboard slitting machine. Background Technology

[0002] A paper slitting machine is a mechanical device that cuts wide sheets of paper into multiple narrow strips. It is commonly used in papermaking machinery and printing and packaging machinery. Compared with ordinary slitting machines, high-efficiency fixed-length slitting machines place greater emphasis on the stability of dynamic cutting and the ability to handle complex shapes.

[0003] Chinese patent CN220576077U discloses a high-efficiency fixed-length slitting machine for cardboard, including a support platform with a feeding assembly. The support platform also includes a clamping assembly and a cutting assembly. The clamping assembly includes a front clamping member, a rear clamping member, and a power component for driving the front and rear clamping members. The cutting assembly further includes a mounting body located between the front and rear clamping members, with a blade and pressure rollers. The front clamping member is used to clamp and convey the cardboard before slitting, and the rear clamping member is used to clamp and convey the cardboard after slitting. This application, through the clamping and cutting assemblies, reduces the possibility of cardboard loosening or shifting during slitting, improves the stability of the cardboard during slitting, and reduces the possibility of the cardboard being scrapped due to its own shift.

[0004] The aforementioned slitting machine has the effect of improving the stability of cardboard slitting. However, when feeding, the pusher of the existing cardboard slitting machine needs to make a full round trip to push out a piece of cardboard, which increases the energy consumption of the slitting machine and results in low processing efficiency. In addition, the cardboard dimensions vary, which limits the adaptability of the slitting machine. Therefore, it is necessary to provide a high-efficiency fixed-length cardboard slitting machine. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency fixed-length cardboard slitting machine to solve the problems of low processing efficiency and poor adaptability of existing slitting machines.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency fixed-length cardboard slitting machine, comprising two worktables, a drive motor, a conveyor belt, a first electric telescopic rod, and a cutting blade assembly, wherein a paper feeding mechanism is provided between the two worktables; the paper feeding mechanism includes a paper support frame and two height limiting frames, the two height limiting frames being fixedly installed on one side of the two worktables respectively, a second electric telescopic rod being fixedly installed on the lower part of the paper support frame, and a mounting base being fixedly installed on the output end of the second electric telescopic rod and slidably mounted on the lower side of the paper support frame, with push frames slidably installed on both sides of the mounting base, and a buffer spring being fixedly installed between the push frames and the mounting base.

[0007] Preferably, the paper holder is flush with the lower conveyor belt, and the pusher extends through the paper holder.

[0008] Preferably, the pusher is composed of several triangular plates, and the inclined surfaces of the triangular plates face the center of the mounting base.

[0009] Preferably, a positioning mechanism is provided between the workbench and the paper holder. The positioning mechanism includes two slide rails, which are respectively fixedly installed on both sides of the paper holder. Limit seats are fixedly installed on both sides of the slide rails. Positioning bolts are threaded through the slide rails and rotatably installed on the workbench. The paper holder has several sliding grooves, and slide seats are slidably installed in the several sliding grooves and fixedly installed on the workbench.

[0010] Preferably, the lower part of the worktable is embedded and slidably mounted between the slide rail and the limiting seat, and the length of the slide rail is equal to the sum of the distances between the worktable and the slide seat.

[0011] Preferably, both sides of one end of the slide are fixedly installed with a stop block, and the stop block is embedded and slidably installed in the slide groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) This high-efficiency fixed-length slitting machine for cardboard uses a second electric telescopic rod to control the mounting base to move back and forth along the paper support frame. When cardboard is stacked between two height limit frames, whenever the mounting base moves and a pusher pushes the cardboard out of the vertical plane and presses it tightly against the mounting base under the action of a buffer spring, the second electric telescopic rod is controlled to move the mounting base in the opposite direction. This pushes the cardboard out from under the height limit frame and into the conveyor belt, thus solving the low efficiency problem of existing slitting machines that require a full round trip to push out a piece of cardboard, and greatly increasing the paper cutting efficiency of the slitting machine.

[0014] 2) This is used for a high-efficiency fixed-length slitting machine for cardboard. By controlling the rotation of the positioning bolts, the worktable can be supported and moved on the guide rail. When the worktable moves, the slide will move forward or backward relative to the paper support frame, thereby extending and retracting the paper support frame. In use, after the cardboard is stacked between the two height limit frames, the positioning bolts are further controlled to make the height limit frames clamp the cardboard, thereby achieving the effect of expanding the capacity of the paper support frame and ensuring that cardboard of different sizes can be stacked between the two height limit frames.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Combination Figures 1-4 A high-efficiency fixed-length cardboard slitting machine includes two worktables 1, a drive motor 2, a conveyor belt 3, a first electric telescopic rod 4, and a cutter assembly 5. A paper feeding mechanism 6 is provided between the two worktables 1. The paper feeding mechanism 6 includes a paper support frame 601 and two height limiting frames 602. The two height limiting frames 602 are respectively fixedly installed on one side of the two worktables 1. A second electric telescopic rod 603 is fixedly installed on the lower part of the paper support frame 601. A mounting base 604 is fixedly installed on the output end of the second electric telescopic rod 603 and slidably installed on the lower side of the paper support frame 601. Push frames 605 are slidably installed on both sides of the mounting base 604. A buffer spring 606 is fixedly installed between the push frame 605 and the mounting base 604.

[0024] The paper holder 601 is flush with the lower conveyor belt 3, allowing the paperboard to move on the paper holder 601 and enter between the conveyor belts 3. The pusher 605 passes through the paper holder 601. The pusher 605 is composed of several triangular plates, with the inclined surfaces of the triangular plates facing the center of the mounting base 604. This allows the paperboard to press against the inclined surfaces of the triangular plates while the buffer spring 606 counteracts the pressure, ensuring that the paperboard is not restricted. The pusher 605 on the other side pushes the paperboard until it enters the conveyor belt 3, and then enters the cutter group 5 under the action of the conveyor belt 3, so that the paper can be cut.

[0025] Example 2

[0026] See Figure 5 A positioning mechanism 7 is provided between the workbench 1 and the paper holder 601. The positioning mechanism 7 includes two slide rails 701, which are fixedly installed on both sides of the paper holder 601. Limit seats 702 are fixedly installed on both sides of the slide rails 701. Positioning bolts 703 are threaded through the slide rails 701 and rotatably installed on the workbench 1. Several slide grooves 704 are provided on the paper holder 601. Slide seats 705 are slidably installed in the several slide grooves 704 and fixedly installed on the workbench 1.

[0027] The lower part of the workbench 1 is embedded and slidably installed between the slide rail 701 and the limit seat 702. When the control positioning bolt 703 moves the workbench 1 on the slide rail 701, the length of the paper holder 601 will be extended. The length of the slide rail 701 is equal to the sum of the distances between the workbench 1 and the slide block 705. Both sides of one end of the slide block 705 are fixedly installed with blocks, and the blocks are embedded and slidably installed in the slide groove 704, so that the slide block 705 moves relative to the paper holder 601, thereby expanding the capacity of the paper holder 601 and ensuring that cardboard of different sizes can be stacked between the two height limit frames 602.

[0028] In actual operation, the cardboard is stacked between two height limit frames 602. By controlling the second electric telescopic rod 603, the mounting base 604 is moved back and forth. When the mounting base 604 reaches the edge of the cardboard, the pusher 605 near the edge of the cardboard will push the cardboard under the action of the buffer spring 606. Benefiting from the fact that both pushers 605 can push the cardboard, the effect of fast feeding is achieved, thereby improving the efficiency of cardboard cutting.

[0029] By controlling the positioning bolt 703 to support the workbench 1 to move on the slide rail 701, the slide block 605 is further moved within the paper holder 601, and the paper holder 601 is extended or retracted. In use, several cardboards are stacked between the two height limit frames 602, and the positioning bolt 703 is further controlled to make the two height limit frames 602 clamp the edges of the cardboard, so that the angle of the cardboard is flattened, and at the same time, it is ensured that the cardboard smoothly enters the conveyor belt 3 during the cardboard conveying process.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
