Description

Technical Field

[0001] This utility model relates to the field of cardboard cutting technology, and in particular to a cardboard cutting device with precise positioning function. Background Technology

[0002] Cardboard is the basic material for making cartons, generally composed of multiple layers of pulp fibers. The main reason for cutting it is to make it conform to specific size and specifications, facilitating subsequent processing and assembly into cartons of different sizes and shapes to meet the actual needs of various product packaging.

[0003] The positioning mechanism of existing cardboard cutting equipment has significant shortcomings. The main problem lies in the lack of a dedicated component for cleaning the cardboard. When the cutting blade descends to perform the cutting operation, hard particles in the impurities, such as sand, act like tiny abrasives, constantly rubbing against the blade as it moves, causing scratches and wear, and reducing the blade's sharpness. With each cut, the blade wear becomes increasingly severe, resulting in a rough cut surface that fails to meet the precision and quality requirements of carton production. Frequent blade replacements also increase production costs and downtime. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a carton and cardboard cutting device with precise positioning function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cardboard cutting device with precise positioning function includes a fixed plate, a cardboard body, a cutting blade, and two positioning plates. The fixed plate has a placement groove with a cutting opening on the bottom wall of the placement groove. A cylinder is suspended above the fixed plate and connected to the cutting blade through a connecting mechanism. Both positioning plates have cavities. T-shaped rods are fixedly and movably installed on the two positioning plates respectively. A piston plate connected to the T-shaped rod is provided in one of the cavities. A sliding plate is mounted on the cutting blade and slidably sleeved on the T-shaped rod. One positioning plate has an air inlet and an air outlet communicating with the cavity, and the other positioning plate has a dust inlet and a dust collection outlet communicating with the cavity. A cover plate is provided inside the dust collection outlet.

[0007] Preferably, the connecting mechanism includes a connecting frame mounted on the telescopic end of the cylinder, and the cutting blade is connected to the connecting frame by fixing bolts.

[0008] Preferably, a first spring is sleeved on the outside of the fixed T-shaped rod, and the two ends of the first spring are respectively connected to the outer wall of the positioning plate and the outer wall of the sliding plate.

[0009] Preferably, a second spring is sleeved on the outside of the movable T-shaped rod, and a limiting block is fixed on the T-shaped rod. The two ends of the second spring are respectively connected to the outer wall of the positioning plate and the outer wall of the limiting block.

[0010] Preferably, both the air inlet and the air outlet are provided with a first protective net, the cover plate is provided with an air leakage port, and the air leakage port is provided with a second protective net.

[0011] Preferably, the cover plate is provided with a U-shaped lifting bracket, and a rubber pad is provided on the outer wall of the cover plate that contacts the material inlet, and the surface of the rubber pad is provided with anti-slip texture.

[0012] The beneficial effects of this utility model are:

[0013] 1. By utilizing a cylinder to drive the cutting blade and positioning plate in tandem, precise cutting and positioning of the cardboard body is achieved. During the cutting process, the positioning plate first contacts the cardboard and maintains a stable downward pressure under the action of a spring, effectively fixing the position of the cardboard and preventing it from shifting during cutting, thereby ensuring cutting accuracy.

[0014] 2. It has the function of automatically cleaning impurities on the cardboard surface during the cutting operation, without the need for additional manual intervention or special cleaning process, which improves production efficiency and can effectively prevent impurities from having an adverse effect on cutting quality and subsequent carton processing, such as avoiding problems such as uneven cut surfaces and poor carton bonding caused by impurities.

[0015] 3. The left-side positioning plate is equipped with a dust inlet, a dust outlet, and corresponding cover plates, facilitating the collection and cleaning of impurities. Simultaneously, the air vents and second protective mesh on the cover plates ensure gas discharge while preventing impurity leakage, further optimizing the collection and treatment of impurities, helping to maintain a clean internal environment and extend the equipment's service life.

Detailed Implementation

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A cardboard cutting device with precise positioning function includes a fixed plate 1, a cardboard body 3, a cutting blade 6, and two positioning plates 9. The fixed plate 1 is provided with a placement groove 2, and the bottom wall of the placement groove 2 is provided with a cutting opening 8. A cylinder 4 is suspended and installed above the fixed plate 1. The cylinder 4 is connected to the cutting blade 6 through a connecting mechanism. Both positioning plates 9 are provided with cavities. T-shaped rods 10 are fixedly and movably installed on the two positioning plates 9 respectively. As shown in the figure, the left T-shaped rod 10 is fixedly installed on the positioning plate 9, and the right T-shaped rod 10 slides through the outer wall of the positioning plate 9 and extends into the cavity inside the positioning plate 9.

[0023] One of the cavities is equipped with a piston plate 18 connected to the T-shaped rod 10. The piston plate 18 is slidably mounted in the cavity.

[0024] The cutting blade 6 is equipped with a sliding plate 12 that is slidably sleeved on the T-shaped rod 10. One of the positioning plates 9 is provided with an air inlet and an air outlet that communicate with the cavity. That is, on the right positioning plate 9, the higher one is the air inlet and the lower one is the air outlet. Both the air inlet and the air outlet are provided with a first protective net 14. The air inlet is provided with a first one-way valve and the air outlet is provided with a second one-way valve, which ensures that gas can only be drawn in through the air inlet and can only be discharged through the air outlet. The first protective net 14 prevents impurities from entering the cavity inside the positioning plate 9.

[0025] Another positioning plate 9 has a dust inlet and a dust removal port communicating with the cavity. The dust removal port is equipped with a cover plate 16. Gas is ejected from the air outlet, which blows impurities on the surface of the cardboard body 3 into the cavity inside the positioning plate 9 through the dust inlet. Opening the cover plate 16 opens the dust removal port, making it convenient to enter the cavity and remove impurities. The bottom wall of the cavity is raised to ensure that impurities accumulate near the dust removal port.

[0026] The connecting mechanism includes a connecting frame 5 mounted on the telescopic end of the cylinder 4, and the cutting blade 6 is connected to the connecting frame 5 via fixing bolts 7. The connecting frame 5 enables the connection between the cutting blade 6 and the cylinder 4, the other end of which is mounted on the wall or ceiling of the processing area.

[0027] A first spring 11 is fitted around the fixed T-shaped rod 10, with its two ends connected to the outer walls of the positioning plate 9 and the sliding plate 12, respectively. A second spring is fitted around the movable T-shaped rod 10, and a limiting block 13 is fixedly mounted on the T-shaped rod 10. The two ends of the second spring are connected to the outer walls of the positioning plate 9 and the limiting block 13, respectively. The elastic potential energy provided by the first spring 11 and the second spring can increase the downward pressure of the positioning plate 9 on the cardboard body 3.

[0028] Both the air inlet and outlet are equipped with a first protective mesh 14, and the cover plate 16 has a vent with a second protective mesh 17 inside. This vent allows impurities entering the cavity to be trapped, while the gas is discharged through the second protective mesh 17.

[0029] The cover plate 16 is equipped with a U-shaped lifting bracket, and a rubber pad is provided on the outer wall of the cover plate 16 that contacts the material inlet 15. The surface of the rubber pad is provided with anti-slip texture. The lifting bracket facilitates the lifting of the cover plate 16, and the rubber pad ensures that the cover plate 16 is stably installed within the material inlet 15 and cannot be moved without the help of the lifting bracket.

[0030] In use, the cylinder 4 is initially in a retracted state, and the slide plate 12 contacts the head of the T-shaped rod 10. Then, the cardboard body 3 is placed in the placement groove 2, with the cut-off point corresponding to the cutting opening 8. The cylinder 4 is then activated to extend it, causing the cutting blade 6 and the positioning plate 9 to descend. The positioning plate 9 contacts the cardboard body 3 first, and then the cylinder 4 continues to extend. At this time, the slide plate 12 slides down on the two T-shaped rods 10. The first spring 11 on the left is compressed and the slide plate 12 continues to descend. After the right slide plate 12 presses down on the limiting block 13, it drives the entire T-shaped rod 10 to descend and compresses the second spring. At this time, the piston plate 18 in the cavity inside the right positioning plate 9 will descend (there is air in this cavity). As the piston plate 18 descends, the gas will be blown out from the air outlet, blowing the impurities on the surface of the cardboard body 3 into the cavity inside the left positioning plate 9 through the dust inlet. Due to the second protective net 17, the gas will be discharged, and the impurities will remain in the cavity. As cylinder 4 continues to extend, cutting blade 6 finally completes the cutting operation of cardboard body 3.

[0031] After the cutting is completed, the cylinder 4 retracts, and the cutting blade 6 rises first. The positioning plate 9 prevents the cut cardboard body 3 from rising with the cutting blade 6, ensuring that it will not be messy after cutting.

[0032] After the cutting blade 6 rises, the positioning plate 9 will rise as well. The first spring 11 and the second spring will both return to their original positions during this process. The piston plate 18 will rise in the cavity and draw in air again through the air inlet to wait for the next use.

[0033] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
