DETAILED DESCRIPTION

[0023] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. The preferred embodiments in the description are only used as examples. All other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the present invention.

[0024] Example 1:

[0025] like Figure 1-Figure 4 As shown, this embodiment adopts the following technical solution: it includes a cutting assembly 1, a feeding rack 2 and a collection box 3. The feeding rack 2 is fixedly provided on the cutting assembly 1, and the collection box 3 is fixedly provided on the front side of the cutting assembly 1;

[0026] It also contains:

[0027] A motor 4 is fixedly mounted on the left side wall of the collection box 3. Threaded rods 5 are screwed together in two sliding grooves on the inner bottom wall of the collection box 3 via bearings. The output shaft of the motor 4 is connected to the end of one of the threaded rods 5.

[0028] Sliding blocks 6, there are two sliding blocks 6, which are movably arranged in two sliding grooves respectively, and the threaded rod 5 is screwed through the sliding blocks 6 by screwing. A squeezing plate 7 is movably arranged in the collection box 3, and the squeezing plate 7 is fixedly arranged on the two sliding blocks 6. An accordion cover 16 is fixedly arranged in the sliding groove, and one end of the accordion cover 16 is connected to the sliding block 6. The accordion cover 16 can shield and protect the sliding groove to prevent corrugated cardboard waste from falling into the sliding groove and affecting the movement of the sliding block 6;

[0029] There are two vertical rods 8, which are respectively screwed together at the front and rear sides of the left side wall of the collection box 3 through bearings. The lower ends of the vertical rods 8 are screwed together with the threaded rod 5 through a bevel gear pair. Two pulleys 9 are provided on the right side of the collection box 3. The pulleys 9 are fixedly sleeved on the threaded rod 5 and the two pulleys 9 are connected by a sleeved belt.

[0030] The box cover 10 is slidably set at the opening above the collection box 3 through a slide rail pair. Racks 11 are fixedly set in the two strip grooves opened on the lower side wall of the box cover 10, and a gear 12 meshing with the rack 11 is fixedly set at the upper end of the vertical rod 8.

[0031] Example 2:

[0032] like Figure 1-Figure 3 As shown, this embodiment is improved on the basis of the first embodiment, and the feeding frame 2 is provided with a limiting component 13, which includes:

[0033] There are two movable blocks 13-1, which are movably arranged in two movable grooves in the side walls of the feeding rack 2. A spring 13-2 is fixedly arranged at the lower part of the movable block 13-1, and the lower end of the spring 13-2 is fixedly connected to the movable groove;

[0034] There are two rotating rods 13-3, which are hinged on the left side walls of the two movable blocks 13-1 respectively. A rotating sleeve 13-4 is provided on the rotating rod 13-3 through a bearing screw connection. A storage groove 14 is provided on the side wall of the feed rack 2 at the opening of the movable groove. The rotating sleeve 13-4 is movably abutted in the storage groove 14. When the cutting mechanism is idle, the rotating sleeve 13-4 can be rotated to the storage groove 14 for storage. A rubber sleeve 15 is fixedly provided on the rotating sleeve 13-4, and the rubber sleeve 15 can achieve buffering between the rotating sleeve 13-4 and the corrugated cardboard.

[0035] When using the present invention, the corrugated cardboard is placed on the feeding rack 2, and then the rotating sleeve 13-4 is flipped out of the receiving slot 14 through the rotating rod 13-3. Then the spring 13-2 is shortened to drive the movable block 13-1 to move downward. The movable block 13-1 drives the rotating sleeve 13-4 to move downward through the rotating rod 13-3, so that the rotating sleeve 13-4 contacts the corrugated cardboard and applies a certain pressure to the corrugated cardboard to avoid deviation during the movement and cutting process. After that, the corrugated cardboard can be driven to move by the feeding rack 2, so that the cutting assembly 1 can cut the corrugated cardboard, and the waste residue of the corrugated cardboard after cutting will fall off. After the waste paper is squeezed out of the collecting box 3, the waste paper will fall into the collecting box 3, and then the motor 4 can be started, and with the cooperation of the pulley 9 and the belt, the threaded rods 5 on both sides can rotate synchronously. At this time, the sliding block 6 can drive the extrusion plate 7 to move to the left, so that the extrusion plate 7 can push and squeeze the waste paper of corrugated cardboard in the collecting box 3 to the left. When the threaded rod 5 rotates, the vertical rod 8 will be driven to rotate through the bevel gear pair, and the vertical rod 8 will drive the gear 12 to rotate. Through the engagement of the gear 12 with the rack 11, the extrusion plate 7 can move to the left while the box cover 10 can move to the right, thereby preventing the waste paper of corrugated cardboard from moving upward out of the collecting box 3 during the extrusion process in the collecting box 3.

[0036] After adopting the above structure, the beneficial effects of this specific embodiment are as follows:

[0037] 1. Through the cooperation of the motor 4, the threaded rod 5, the sliding block 6, the extrusion plate 7, the vertical rod 8, the pulley 9, the box cover 10, the rack 11 and the gear 12, not only can the collected corrugated cardboard waste be compressed, so that the storage space in the collection box 3 can be fully utilized, but also the corrugated cardboard waste can be prevented from moving upward during the compression process;

[0038] 2. The cooperation of the limiting component 13 can prevent the corrugated cardboard from deflecting during the cutting process.

[0039] For those skilled in the art, they can modify the technical solutions described in the aforementioned embodiments and make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the scope of protection of the present utility model.
