Description

Technical Field

[0001] The utility model relates to the technical field of high-strength paperboard production, in particular to high-strength paperboard production equipment. Background Art

[0002] High-strength cardboard is a cardboard material with excellent performance and high quality. Its characteristics include: excellent compressive resistance, able to withstand large vertical pressure without deformation or damage. For example, it can provide reliable protection when packaging heavy objects such as electrical appliances and mechanical equipment. It has good folding resistance and can be folded multiple times without easily breaking. This makes it excellent for making complex-shaped packaging boxes or display racks. Its high stiffness maintains its own shape and structural stability, and it is not easy to bend or sag. For example, it is used in the production of bookshelf partitions, file boxes, etc.

[0003] Some existing high-strength cardboard production equipment, when pressing high-strength cardboard production materials, put the high-strength cardboard production materials into the inside of the pressing groove, and then use the motor to drive the threaded rod and the internal threaded cylinder to move downward to apply pressure to the pressing block to press the high-strength cardboard production materials;

[0004] In traditional high-strength cardboard production equipment, when pressing high-strength cardboard production materials, the high-strength cardboard production materials are only subjected to pressure on one side, which may cause uneven pressure on the high-strength cardboard production materials and poor pressing effect. For this reason, we propose a high-strength cardboard production equipment. Utility Model Content

When the high-strength cardboard production material is pressed, the high-strength cardboard production material will be subjected to pressing forces on the upper and lower sides, so that the high-strength cardboard production material is pressed more evenly and the pressing effect is better, which can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a high-strength cardboard production device, comprising a frame, a bracket provided at the upper end of the frame, a pressing groove provided on the upper surface of the frame, a push plate slidably connected to the interior of the pressing groove, a pressing mechanism and an auxiliary pressing mechanism;

The upper end of the internal threaded cylinder is fixedly connected to the middle part of the lower surface of the push plate. When the high-strength cardboard production material is pressed, the high-strength cardboard production material will be subjected to pressing forces on the upper and lower sides, so that the high-strength cardboard production material is pressed more evenly and the pressing effect is better.

[0009] Furthermore, a control switch group is provided on the outside of the rack, and an input end of the control switch group is electrically connected to an external power supply to provide electrical connection for various electrical appliances.

[0010] Furthermore, the pressing mechanism also includes a bidirectional screw rod, which is rotatably connected to the upper end between the left and right inner sides of the bracket. The left and right ends of the bidirectional screw rod are respectively threadedly connected to the threaded holes on the lower side of the adjacent T-shaped slider to provide a sliding connection.

[0014] Furthermore, a strip-shaped avoidance hole corresponding to gear 1 is opened at the upper end of the bracket to provide a limit.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the high-strength cardboard production equipment has the following advantages:

[0016] Driven by motor one, gear one rotates, and gear one drives the bidirectional screw to rotate through the meshing gear two. The bidirectional screw forms a trapezoidal support structure through the T-shaped slider, U-shaped block, connecting rod and U-shaped seat, pushing the slide plate downward, so that the pressing block has a uniform pressing force. Driven by motor two, the threaded rod rotates and drives the internal threaded cylinder to lift the push plate upward, so that the cardboard has two upper and lower pressing forces during pressing, making the cardboard harder, thereby achieving high-strength cardboard production materials. The materials will be subjected to pressing forces from both sides, so that the high-strength cardboard production materials are more evenly pressed and the pressing effect is better.

The internal threaded barrel 93 will push the push plate 5 upward, so that the pressed cardboard falls off quickly.

[0025] The working principle of the high-strength cardboard production equipment provided by the present invention is as follows: when producing high-strength cardboard, first, raw materials such as pulp and fiber are injected into the interior of the pressing groove 4, and then the control switch group 10 is adjusted to operate the motor 1 71, and the output shaft of the motor 1 71 drives the gear 1 72 to rotate. The rotation of the gear 1 72 will drive the meshing gear 2 73 to rotate, and the rotation of the gear 2 73 will drive the bidirectional screw rod 74 to rotate.

The pressing block 8 moves downward and presses the pulp, fiber and other raw materials inside the pressing groove 4. Then, in order to make the cardboard have high strength, the control switch group 10 is adjusted and the motor 2 91 is operated. The output shaft of the motor 2 91 drives the threaded rod 92 to rotate. The rotation of the threaded rod 92 drives the internal threaded barrel 93 of the thread to move upward, thereby pushing the push plate 5 upward, so that the pulp, fiber and other raw materials have upper and lower holding forces, making the cardboard harder. After pressing, the motor 1 71 operates counterclockwise, the pressing block 8 is lifted, and the motor 2 91 continues to operate. The internal threaded barrel 93 pushes the push plate 5 upward, so that the pressed cardboard falls off quickly.
