Description

Technical Field

[0002] Existing printing and graphic shops basically use manual methods to make paper boxes, covers, etc., and cut pictures by hand. With the improvement of living standards and people's pursuit of exquisite life, the amount of product packaging is not only increasing, but also the specifications and varieties are increasing, and the quality requirements are getting higher and higher. Manual production can no longer adapt to the development of the times. In order to adapt to the needs of the times, reduce the labor intensity of workers, and improve the life experience of consumers, a device with automatic feeding, automatic cutting, and automatic storage is needed, so the graphic cutting machine came into being.

[0003] In order to improve processing efficiency, the graphic cutting machine has an automatic paper feeding device that can transport the cardboard to the cutting platform. In the prior art, the cardboard is stacked and placed in the feeding area, and the top layer of cardboard is adsorbed by a vacuum adsorption device, and the vacuum adsorption device moves to place the cardboard on the cutting platform. However, relying on the adsorption device to absorb the cardboard is prone to the problem of absorbing multiple sheets of paper at the same time. Especially for cardboard with good air permeability, the paper feeding device cannot ensure that only one sheet of paper is delivered each time. The excess cardboard placed on the cutting platform will cause material loss after cutting. Utility Model Content

[0004] The utility model aims to solve the above problems in the prior art and proposes a material suction mechanism that can achieve good paper separation and ensure that paperboards are output piece by piece.

DETAILED DESCRIPTION

[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0024] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0025] like Figure 1 and Figure 2 As shown, the utility model provides a cutting device, comprising:

[0026] A cutting platform 10 is provided with a material storage area 11 for stacking and storing materials to be cut, and a cutting area 12 for cutting the materials to be cut;

[0027] The crossbeam 20 is slidably connected to the cutting platform 10, and a suction mechanism 30 is installed on the crossbeam 20. The suction mechanism 30 sucks the materials to be cut in the storage area 11 and places them one by one in the cutting area 12, wherein the suction mechanism 30 includes a fixed rod 31 connected to the crossbeam 20, and a plurality of first suction cup structures 32 and second suction cup structures 33 are connected along the length direction of the fixed rod 31, and at least one first suction cup structure 32 is arranged between two adjacent second suction cup structures 33, and the second suction cup structure 33 is a Bernoulli suction cup.

[0028] It is worth mentioning that the working principle of the Bernoulli suction cup in this embodiment is: the external compressed air flows at high speed through the small gap between the suction cup and the surface of the object to be transported. As the air flow speed increases, the air pressure flowing through the gap decreases, thereby forming a low-pressure area between the suction cup and the object. Since the pressure of the surrounding air is relatively high, this low-pressure area pushes the object toward the suction cup, so that the object can be adsorbed without direct contact.

[0029] In other words, the compressed air generated at the air outlet of the Bernoulli suction cup passes through the uppermost layer of breathable material and is pressed toward the second-upper layer of breathable material, so that the uppermost layer of breathable material is separated from the second-upper layer of breathable material, and the reaction force generated by the compressed air passing through the uppermost layer of breathable material when hitting the second-upper layer of breathable material causes the uppermost layer of breathable material and the Bernoulli suction cup to form non-contact adsorption, ultimately achieving the separation of the uppermost layer of breathable material from the second-upper layer of breathable material.

[0030] In addition, a plurality of protrusions are provided at the suction cup mouth of the Bernoulli suction cup, wherein a space surrounded by the plurality of protrusions forms a negative pressure. The Bernoulli suction cup is an existing suction cup structure and can be purchased directly. Therefore, the structure of the Bernoulli suction cup will not be described in detail here.

[0031] The utility model provides a cutting device, which realizes the output of air-permeable materials piece by piece through the cooperation between the first suction cup structure 32 and the second suction cup structure 33.

[0032] Further preferably, the suction cup structures located at both ends of the fixing rod 31 are first suction cup structures 32 , and the plurality of second suction cup structures 33 are located between the two first suction cup structures 32 at both ends of the fixing rod 31 .

[0033] Such a layout ensures that the breathable material will not "fall" on both sides along its moving direction, and ensures that after the breathable material moves from the material storage area 11 to the cutting area 12, it can be laid flat on the cutting area 12 to avoid wrinkles in the material.

[0034] Further preferably, the suction positions of the first suction cup structure 32 and the second suction cup structure 33 are located on a side of the material to be cut close to the cutting area 12 .

[0035] By adopting such a suction position, the material to be cut in the material storage area 11 enters the cutting area 12 in a "dragged" manner after being sucked by the first suction cup structure 32 and the second suction cup structure 33, ensuring that the material to be cut always remains flat during the movement, thereby avoiding the occurrence of wrinkles in the material.

[0036] Further preferably, a plurality of first suction cup structures 32 are distributed on the fixing rod 31 at equal distances.

[0037] Preferably, the first suction cup structure 32 includes a suction cup seat 321 connected to the fixing rod 31, and a quick release joint 322 is connected to one end of the suction cup seat 321, and a suction cup 323 is connected to the other end, wherein a negative pressure straw is connected to the quick release joint 322, so that negative pressure is formed at the suction cup mouth of the suction cup 323.

[0038] In this embodiment, the diameter of the end of the suction cup 323 away from the suction cup seat 321 is smaller, thereby reducing the contact area between the first suction cup structure 32 and the material to be cut, thereby reducing the suction force of the first suction cup structure 32 when sucking the material to be cut, and avoiding the simultaneous output of multiple materials to be cut.

[0039] Preferably, a cylinder 34 is provided at each end of the fixed rod 31, and the cylinder body of the cylinder 34 is connected to the cross beam 20, and the piston rod of the cylinder 34 is connected to the fixed rod 31 through a connecting block 35, wherein the fixed rod 31 is driven by the cylinder 34 to move up and down in a direction perpendicular to the cutting area 12.

[0040] Further preferably, the fixed rod 31 is arranged in a "J" shape, and the two cylinders 34 are located at both ends of the fixed rod 31, and the first suction cup structure 32 and the second suction cup structure 33 are located in the middle of the fixed rod 31, wherein there is a height difference between the connecting plane where the output end of the cylinder 34 is connected to the fixed rod 31, and the connecting plane where the first suction cup structure 32 is connected to the fixed rod 31.

[0041] Preferably, an elastic member 36 is further included, one end of the elastic member 36 is connected to the cylinder body of the cylinder 34, and the other end of the elastic member 36 is connected to the connecting block 35, wherein the elastic member 36 is arranged at an angle.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.
