Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, and in particular to a die-cutting machine for carton production that is easy to clean. Background Technology

[0002] Boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various specifications and models. A carton die-cutting machine is a machine used for die-cutting cardboard in the carton forming process. It is used to die-cut cardboard during carton production.

[0003] Chinese Patent Publication No. CN220720422U discloses a convenient-to-clean die-cutting machine for cardboard box production, including a die-cutting table and a collection box. A vertical plate is fixedly connected to the top wall of the die-cutting table, a horizontal plate is fixedly connected to the side wall of the vertical plate, and an electric telescopic rod is fixedly connected to the top wall of the horizontal plate. A mounting plate is fixedly connected to the movable end of the electric telescopic rod. The cardboard is pressed by a positioning block, a sliding groove, a spring, and a sliding rod. Cardboard debris scattered in different locations is cleaned by a reciprocating screw, a threaded block, a suction pipe, and a blower. The existing technical solution has the following shortcomings: While the device uses the movement of the reciprocating screw to move the suction pipe and thus clean cardboard debris, the cardboard is placed horizontally, and the debris is located in various corners of the cardboard during die-cutting. Since the suction pipe's suction direction is obliquely upward, the debris easily gets stuck on the formed cardboard during movement, resulting in debris residue. Therefore, there is room for improvement. Utility Model Content

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

[0022] Please see Figures 1-4 One embodiment of this utility model is a die-cutting machine for producing cartons that is easy to clean, including a housing 1. Two parallel electric conveyor belts 3 are installed inside the housing 1, and a positioning plate 5 is fixedly connected to the top of the electric conveyor belts 3.

[0023] A lifting mechanism 9 is provided on the side of the top of the positioning plate 5 away from the triangular positioning block 7. The lifting mechanism 9 includes a groove 91 opened on one side of the positioning plate 5, and a flip plate 92 is rotatably connected to the top of the groove 91. An electric telescopic rod 94 is fixed to the bottom of the groove 91, and a ball is provided at the top of the electric telescopic rod 94. The ball abuts against the bottom of the flip plate 92. Multiple protrusions 93 are provided at equal intervals on one side of the bottom of the flip plate 92.

[0024] The pivot of the flip plate 92 is located on the side of the groove 91 near the triangular positioning block 7, and the electric telescopic rod 94 is located on the central axis of the flip plate 92.

[0025] The cross-section of the protrusion 93 is semi-circular, and the protrusion 93 is initially located on the side of the electric telescopic rod 94 away from the triangular positioning block 7.

[0026] Specifically, such as Figure 1 , Figure 4 As shown, when in use, the flip plate 92 is lifted on one side to raise the cardboard, making it easier to extract the cardboard. The protrusion 93 causes the flip plate 92 to vibrate when it is lifted, thereby promoting the loosening of debris.

[0027] Inside the housing 1, a guide plate 4 is fixed, and the guide plate 4 passes through the upper and lower ends of the electric conveyor belt 3. The top of the guide plate 4 abuts against the bottom of the upper conveyor belt of the electric conveyor belt 3. A die-cutting machine knife holder 2 is provided on one side of the housing 1, and the die-cutting machine knife holder 2 is located above the guide plate 4. A collecting mechanism 6 is provided on the bottom side of the guide plate 4 away from the die-cutting machine knife holder 2.

[0028] The collection mechanism 6 includes a collection box 61 installed on one side of the bottom of the guide plate 4, and a drop outlet 62 is connected between the top of the collection box 61 and the guide plate 4. A dust suction fan 64 is installed at the bottom of the collection box 61, and a filter screen 63 is fixed inside the collection box 61 above the dust suction fan 64. A discharge cabinet door 65 is installed on one side of the collection box 61.

[0029] The opening size of the drop hole 62 is matched with the opening size of the through hole 81;

[0030] The filter screen 63 is tilted, and the discharge cabinet door 65 is located on the side where the filter screen 63 is lower.

[0031] Two triangular positioning blocks 7 are arranged opposite each other on one side of the top of the positioning plate 5. An opening and closing component 8 is provided inside the positioning plate 5. The opening and closing component 8 includes a through hole 81 opened inside the positioning plate 5. A flip baffle 82 is rotatably connected inside the through hole 81. The rotating shaft of the flip baffle 82 is located on the side of the through hole 81 close to the die-cutting machine knife holder 2. A slider 83 is installed on the bottom side of the flip baffle 82 away from the rotating shaft.

[0032] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, during use, the drop outlet 62 and the opening and closing component 8 work together to realize the automatic opening and closing of the flip baffle 82, and the vacuum fan 64 can directly absorb the debris on the cardboard, promoting the downward fall of the debris.

[0033] Working principle: When using this utility model, first place the cardboard on the positioning plate 5, so that the two corners of the cardboard are inserted into the interior of the triangular positioning block 7. Then start the electric conveyor belt 3, so that the electric conveyor belt 3 drives the positioning plate 5 to approach the die-cutting machine knife holder 2. During the movement of the positioning plate 5, it is affected by the side of the drop outlet 62, so that the flipping baffle 82 gradually flips to a horizontal state. When the positioning plate 5 moves to the bottom of the die-cutting machine knife holder 2, the knife in the die-cutting machine knife holder 2 is activated to press down, so that the knife cuts the cardboard on the positioning plate 5.

[0034] Secondly, the electric conveyor belt 3 rotates in the reverse direction, causing the positioning plate 5 to reset, and then the position of the flipping baffle 82 and the drop outlet 62 to correspond, causing one side of the flipping baffle 82 to flip downward, so that the bottom of the cardboard on the positioning plate 5 is directly above the dust collector 64. The dust collector 64 is started, generating a downward negative pressure air force, causing the cutting debris on the cardboard to fall downward into the collection box 61 and onto the filter screen 63, accumulating along the filter screen 63 towards the side of the discharge cabinet door 65.

[0035] Finally, the electric telescopic rod 94 is extended, so that the ball bearing at the top of the electric telescopic rod 94 contacts the protrusion 93 at the bottom of the flip plate 92. Since there are multiple protrusions 93, the bottom of the flip plate 92 is uneven, so that when one side of the flip plate 92 is lifted, it vibrates, thereby lifting one side of the cardboard and causing vibration, which further promotes the loosening of debris and cardboard. At the same time, since one side of the cardboard is lifted, it is easier to extract the cardboard.
